A 73-year-old man was admitted to the hospital with progressive abdominal and hip pain of several weeks’ duration that was accompanied by unilateral swelling of the left leg. He had a medical history of hypertension, hyperlipidemia, and prediabetes. Computed tomography (CT) showed extensive intra-abdominal, retroperitoneal, and pelvic lymphadenopathy in addition to poorly defined hepatic lesions.

A CT-guided core biopsy of a left inguinal lymph node showed Burkitt lymphoma. Fluorescence in situ hybridization was positive for oncogene c-MYC rearrangement on chromosome 8q24 and negative for B-cell lymphoma 2 (BCL2) and B-cell lymphoma 6 (BCL6) gene rearrangements. Flow cytometry demonstrated an aberrant population of κ light chain-restricted CD5⁻CD10⁺ B lymphocytes.

The patient’s overall disease burden was consistent with stage IV Burkitt lymphoma. R-miniCHOP chemotherapy—rituximab plus a reduced dose of cyclophosphamide, doxorubicin, vincristine sulfate, and prednisone—was initiated. Approximately 2 weeks after chemotherapy was initiated, the patient developed a firm erythematous eruption on the left hip (Figure 1A). His regimen was then switched to R-EPOCH—rituximab, etoposide phosphate, prednisone, vincristine sulfate, cyclophosphamide, and doxorubicin—at the time of discharge, and he was referred to dermatology due to an initial concern of an adverse reaction to R-EPOCH chemotherapy. The patient denied any pain, pruritus, or irritation. Physical examination showed multifocal, subcutaneous, indurated, erythematous and violaceous nodules without epidermal changes. Some nodules on the lateral aspect of the hip coalesced to form firm plaques.

A punch biopsy specimen showed markedly atypical lymphocytes with enlarged nuclei and scant cytoplasm present throughout the dermis (Figures 2A and 2B). Numerous apoptotic cells and cellular debris were seen. Immunohistochemical staining demonstrated that the lymphocytic infiltrate comprised CD79a⁺ B cells that were positive for Bcl-6 and CD10 and negative for Bcl-2 (Figures 2C and 2D). There also was diminished focal expression of CD20. Ki-67 protein staining was intensely positive and demonstrated a very high proliferative index.

Taken together, these findings were consistent with a diagnosis of cutaneous metastasis of Burkitt lymphoma. The patient’s cutaneous lesions improved after continued aggressive chemotherapy. At follow-up 2 weeks after biopsy, he was receiving his second round of R-EPOCH chemotherapy with appreciable regression of skin lesions (Figure 1B). However, he then developed right-side double vision, ptosis, and right-side facial paresthesia. Although magnetic resonance imaging of the brain and lumbar puncture did not show evidence of central nervous system involvement, the chemotherapy regimen was switched to dose-adjusted CVAD-R—hypercyclophosphamide, vincristine, doxorubicin hydrochloride, and dexamethasone plus rituximab—for empiric treatment of central nervous system disease. Although treatment was complicated by sepsis with extended-spectrum β-lactamase-producing Enterobacter cloacae, Burkitt lymphoma was found to be in remission after 3 cycles of CVAD-R and 5 months of chemotherapy.

Burkitt lymphoma is a B-cell non-Hodgkin malignancy caused by translocation of chromosome 8 and chromosome 14, leading to overexpression of c-MYC and subsequent hyperproliferation of B lymphocytes.^1,2 The disease is divided into 3 major categories: sporadic, endemic, and immunodeficiency related.³ The endemic variant is the most prevalent subtype in Africa and is associated with Plasmodium falciparum malaria; the sporadic variant is the most common subtype in the rest of the world.⁴

Burkitt lymphoma is highly aggressive and is characterized by unusually high rates of mitosis and apoptosis that result in abundant cellular debris and a distinctive starry-sky pattern on histopathology.^5,6 Extranodal metastasis is common,⁷ but cutaneous involvement is exceedingly rare, with only a few cases having been reported.^8-14 Cutaneous metastasis of Burkitt lymphoma often is associated with a high overall disease burden and poor prognosis.^8,11

Immunodeficiency-related Burkitt lymphoma is particularly aggressive. Notably, 3 of 7 (42.9%) reported cases of cutaneous Burkitt lymphoma occurred in HIV-positive patients.^11,13 In one case, cutaneous involvement was the first sign of relapsed disease that had been in remission.¹²

Although c-MYC rearrangement is required to make a diagnosis of Burkitt lymphoma, the disease also is present in a minority of cases of diffuse large B-cell lymphoma (DLBCL)(6%).¹⁵ Although DLBCL typically can be differentiated from Burkitt lymphoma by the large nuclear size and characteristic vesicular nuclei of B cells, few cases of DLBCL with c-MYC rearrangement histologically mimic Burkitt lymphoma. However, key features such as immunohistochemical staining for Bcl-2 and CD10 can be used to distinguish these 2 entities.¹⁶ Bcl-2 negativity and CD10 positivity, as seen in our patient, is considered more characteristic of Burkitt lymphoma. This staining pattern in combination with a high Ki-67 fraction (>95%) and the presence of monomorphic medium-sized cells is more consistent with a diagnosis of Burkitt lymphoma than of DLBCL.¹⁷

Earlier case reports have documented that cutaneous lesions of Burkitt lymphoma can occur in a variety of ways. Hematogenous spread is the likely route of metastasis for lesions distant to the primary site or those that have widespread distribution.¹⁸ Alternatively, other reports have suggested that cutaneous metastases can occur from local invasion and subcutaneous extension of malignant cells after a surgical procedure.^10,19 For example, cutaneous Burkitt lymphoma has been reported in the setting of celioscopy, occurring directly at the surgical site.¹⁹ In our patient, we believe that the route of metastatic spread likely was through subcutaneous invasion secondary to CT-guided core biopsy, which was supported by the observation that the onset of cutaneous manifestations was temporally related to the procedure and that the lesions occurred on the skin directly overlying the biopsy site.

In conclusion, we describe an exceedingly rare presentation of cutaneous Burkitt lymphoma in which a surgical procedure likely served as an inciting event that triggered seeding of malignant cells to the skin. Cutaneous spread of Burkitt lymphoma is infrequently reported; all such reports that provide long-term follow-up data have described it in association with high disease burden and often a lethal outcome.^8,11,12 Our patient had complete resolution of cutaneous lesions with chemotherapy. It is unclear if the presence of cutaneous lesions can serve as a prognostic indicator and requires further investigation. However, our case provides preliminary evidence to suggest that cutaneous metastases do not always represent aggressive disease and that cutaneous lesions may respond well to chemotherapy.

Stefan Bornstein, MD, PhD, professor, made it clear during a press conference at the 67th Congress of the German Society of Endocrinology (DGE) that there is more than one interaction between them. Nowadays, one can almost speak of an “endocrine virology and even of the virome as an additional, hormonally metabolically active gland,” said Dr. Bornstein, who will receive the Berthold Medal from the DGE in 2024.

Many questions remain unanswered: “We need a better understanding of the interaction of hormone systems with infectious agents — from basics to therapeutic applications,” emphasized the director of the Medical Clinic and Polyclinic III and the Center for Internal Medicine at the Carl Gustav Carus University Hospital, Dresden, Germany.

If infectious diseases could trigger diabetes and other metabolic diseases, this means that “through vaccination programs, we may be able to prevent the occurrence of common metabolic diseases such as diabetes,” said Dr. Bornstein. He highlighted that many people who experienced severe COVID-19 during the pandemic, or died from it, exhibited diabetes or a pre-metabolic syndrome.

“SARS-CoV-2 has utilized an endocrine signaling pathway to invade our cells and cause damage in the organ systems and inflammation,” said Dr. Bornstein. Conversely, it is now known that infections with coronaviruses or other infectious agents like influenza can significantly worsen metabolic status, diabetes, and other endocrine diseases.
 

SARS-CoV-2 Infects the Beta Cells

Data from the COVID-19 pandemic showed that the likelihood of developing type 1 diabetes significantly increases with a SARS-CoV-2 infection. Researchers led by Dr. Bornstein demonstrated in 2021 that SARS-CoV-2 can infect the insulin-producing cells of the organ. They examined pancreatic tissue from 20 patients who died from COVID-19 using immunofluorescence, immunohistochemistry, RNA in situ hybridization, and electron microscopy.

They found viral SARS-CoV-2 infiltration of the beta cells in all patients. In 11 patients with COVID-19, the expression of ACE2, TMPRSS, and other receptors and factors like DPP4, HMBG1, and NRP1 that can facilitate virus entry was examined. They found that even in the absence of manifest newly onset diabetes, necroptotic cell death, immune cell infiltration, and SARS-CoV-2 infection of the pancreas beta cells can contribute to varying degrees of metabolic disturbance in patients with COVID-19.

In a report published in October 2020, Tim Hollstein, MD, from the Institute for Diabetology and Clinical Metabolic Research at UKSH in Kiel, Germany, and colleagues described the case of a 19-year-old man who developed symptoms of insulin-dependent diabetes after a SARS-CoV-2 infection, without the presence of autoantibodies typical for type 1 diabetes.

The man presented to the emergency department with diabetic ketoacidosis, a C-peptide level of 0.62 µg/L, a blood glucose concentration of 30.6 mmol/L (552 mg/dL), and an A1c level of 16.8%. The patient’s history revealed a probable SARS-CoV-2 infection 5-7 weeks before admission, based on a positive antibody test against SARS-CoV-2.
 

Some Viruses Produce Insulin-Like Proteins

Recent studies have shown that some viruses can produce insulin-like proteins or hormones that interfere with the metabolism of the affected organism, reported Dr. Bornstein. In addition to metabolic regulation, these “viral hormones” also seem to influence cell turnover and cell death.

Dr. Bornstein pointed out that antiviral medications can delay the onset of type 1 diabetes by preserving the function of insulin-producing beta cells. It has also been shown that conventional medications used to treat hormonal disorders can reduce the susceptibility of the organism to infections — such as antidiabetic preparations like DPP-4 inhibitors or metformin.

In a review published in 2023, Nikolaos Perakakis, MD, professor, research group leader at the Paul Langerhans Institute Dresden, Dresden, Germany, Dr. Bornstein, and colleagues discussed scientific evidence for a close mutual dependence between various virus infections and metabolic diseases. They discussed how viruses can lead to the development or progression of metabolic diseases and vice versa and how metabolic diseases can increase the severity of a virus infection.
 

Viruses Favor Metabolic Diseases...

Viruses can favor metabolic diseases by, for example, influencing the regulation of cell survival and specific signaling pathways relevant for cell death, proliferation, or dedifferentiation in important endocrine and metabolic organs. Viruses are also capable of controlling cellular glucose metabolism by modulating glucose transporters, altering glucose uptake, regulating signaling pathways, and stimulating glycolysis in infected cells.

Due to the destruction of beta cells, enteroviruses, but also the mumps virus, parainfluenza virus, or human herpes virus 6, are associated with the development of diabetes. The timing of infection often precedes or coincides with the peak of development of islet autoantibodies. The fact that only a small proportion of patients actually develop type 1 diabetes suggests that genetic background, and likely the timing of infection, play an important role.
 

...And Metabolic Diseases Influence the Course of Infection

Infection with hepatitis C virus (HCV), on the other hand, is associated with an increased risk for type 2 diabetes, with the risk being higher for older individuals with a family history of diabetes. The negative effects of HCV on glucose balance are mainly attributed to increased insulin resistance in the liver. HCV reduces hepatic glucose uptake by downregulating the expression of glucose transporters and additionally impairs insulin signal transduction by inhibiting the PI3K/Akt signaling pathway.

People with obesity, diabetes, or insulin resistance show significant changes in the innate and adaptive functions of the immune system. Regarding the innate immune system, impaired chemotaxis and phagocytosis of neutrophils have been observed in patients with type 2 diabetes.

In the case of obesity, the number of natural killer T cells in adipose tissue decreases, whereas B cells accumulate in adipose tissue and secrete more proinflammatory cytokines. Longitudinal multiomics analyses of various biopsies from individuals with insulin resistance showed a delayed immune response to respiratory virus infections compared with individuals with normal insulin sensitivity.

In a review published in 2023, Nikolaos Perakakis, MD, professor, research group leader at the Paul Langerhans Institute Dresden, Dresden, Germany, Dr. Bornstein, and colleagues discussed scientific evidence for a close mutual dependence between various virus infections and metabolic diseases. They discussed how viruses can lead to the development or progression of metabolic diseases and vice versa and how metabolic diseases can increase the severity of a virus infection.
 

Viruses Favor Metabolic Diseases...

Viruses can favor metabolic diseases by, for example, influencing the regulation of cell survival and specific signaling pathways relevant for cell death, proliferation, or dedifferentiation in important endocrine and metabolic organs. Viruses are also capable of controlling cellular glucose metabolism by modulating glucose transporters, altering glucose uptake, regulating signaling pathways, and stimulating glycolysis in infected cells.

Due to the destruction of beta cells, enteroviruses, but also the mumps virus, parainfluenza virus, or human herpes virus 6, are associated with the development of diabetes. The timing of infection often precedes or coincides with the peak of development of islet autoantibodies. The fact that only a small proportion of patients actually develop type 1 diabetes suggests that genetic background, and likely the timing of infection, play an important role.
 

...And Metabolic Diseases Influence the Course of Infection

Infection with hepatitis C virus (HCV), on the other hand, is associated with an increased risk for type 2 diabetes, with the risk being higher for older individuals with a family history of diabetes. The negative effects of HCV on glucose balance are mainly attributed to increased insulin resistance in the liver. HCV reduces hepatic glucose uptake by downregulating the expression of glucose transporters and additionally impairs insulin signal transduction by inhibiting the PI3K/Akt signaling pathway.

People with obesity, diabetes, or insulin resistance show significant changes in the innate and adaptive functions of the immune system. Regarding the innate immune system, impaired chemotaxis and phagocytosis of neutrophils have been observed in patients with type 2 diabetes.

In the case of obesity, the number of natural killer T cells in adipose tissue decreases, whereas B cells accumulate in adipose tissue and secrete more proinflammatory cytokines. Longitudinal multiomics analyses of various biopsies from individuals with insulin resistance showed a delayed immune response to respiratory virus infections compared with individuals with normal insulin sensitivity.

TOPLINE:

New research shows increased screen time in children aged 12-36 months is associated with reduced verbal interactions between toddlers and their parents, which in turn could affect language development. 

METHODOLOGY:

• The study included data from 220 families in Australia.
• Researchers used advanced speech recognition technology to capture children’s screen time and language environment at home during a 16-hour window every 6 months.
• They adjusted for variables such as the sex of the child, the education level of the mother, and psychological distress in the primary caregiver.

TAKEAWAY: 

• Increases in screen time were associated with decreases in words spoken near children by adults, vocalizations by children, and back-and-forth interactions between adults and children. This correlation was especially notable at age 36 months.
• At age 36 months, each additional minute of screen time was linked to children hearing 6.6 fewer adult words, making 4.9 fewer vocalizations, and participating in 1.1 fewer conversational interactions.
• Based on the average daily screen time at that age seen in the study — 172 minutes (2.87 hours) — “children could be missing out on 1139 adult words, 843 vocalizations, and 194 conversational turns per day,” the researchers estimated.

IN PRACTICE:

“Identifying different ways that screen time could facilitate parent-child interactions, such as through interactive co-viewing, may be important strategies to support families given the current ubiquitous nature of screen time in families’ lives,” the authors of the study wrote.

What children watch and listen to may be an important consideration, according to a developmental scientist who was not involved with the study.

“It could be that less communicative contact with the caregiver is not as detrimental if the screen time is of high quality and developmentally appropriate, educational content,” Marina Bazhydai, PhD, with Lancaster University in Lancaster, United Kingdom, said in her comments on the research. 

SOURCE:

Mary E. Brushe, PhD, with Telethon Kids Institute and the University of Western Australia in Adelaide, was the corresponding author of the study. The research was published online in JAMA Pediatrics.

LIMITATIONS:

The study’s reliance on speech recognition technology did not capture all nuances of screen exposure.

DISCLOSURES:

This study was supported by grants from the Australian National Health and Medical Research Council.

Primary care clinicians have largely welcomed the arrival of Opill, the first over-the-counter (OTC) birth control pill from Perrigo, which will reach US pharmacy shelves this month. Although the medicine has a long-track record of safe use, physicians and nurse practitioners may want to ready themselves to answer questions from patients about shifting to the option.

The switch to OTC status for the norgestrel-only contraceptive has the support of many physician groups, including the American Medical Association, the American Academy of Family Physicians, and the American College of Obstetricians and Gynecologists (ACOG).

The end of the prescription-requirement removes a barrier to access for many women, especially those who lack insurance. But it also will take away a chief reason many women in their childbearing years make appointments with doctors, as they will no longer need prescriptions for birth control pills.

Anne-Marie Amies Oelschlager, MD, professor of obstetrics and gynecology at University of Washington School of Medicine, in Seattle, Washington, said she is also worried that the availability of an OTC pill will lead to missed opportunities to help patients avoid sexually transmitted diseases. For example, patients can get counseling about the need for testing for sexually transmitted diseases at the start of new relationships during a visit made to obtain a prescription for the pill.

“My hope is that they still follow our recommendations, which is to get tested with every partner,” said Dr. Oelschlager, who cares for many patients in their teens. “Adolescents are at a particularly high risk of infection compared to older ones.”

When clinicians do see patients, they may want to raise the issue of the OTC option and proper use. Patients will need to closely read materials provided for Opill, a step they might skip due to the ready access, according to Diana Zuckerman, PhD, president of the nonprofit National Center for Health Research, which scrutinizes the safety of medical products.

“When something is sold over the counter, it’s perceived by individuals as being safe,” Dr. Zuckerman told this news organization. “There’s less concern and a little less interest in reading the instructions and reading the warnings.”
 

Considerations for Safety

The US Food and Drug Administration (FDA) in July approved the sales of a daily 0.075 mg norgestrel tablet without prescription. Perrigo told this news organization that it spent the intervening months ensuring retailers and consumers will receive education on the drug.

One of the biggest challenges for people using Opill may be sticking with the dosing schedule, according to Dr. Oelschlager.

“There are going to be people that have a harder time remembering to take a pill every day,” at the same time, said Dr. Oelschlager, who is chair of ACOG’s Clinical Consensus Gynecology Committee. “We need to watch and see what happens as it becomes more widely available, and people start using it.”

Unexpected vaginal bleeding is the most common adverse event linked to this form of birth control, with over one fifth of participants from one study of the OTC drug reporting this side effect, according to an FDA memo.

“It is more likely to be a tolerability issue rather than a safety issue,” the FDA wrote.

Many prescription of birth control options contain estrogen, which is associated with venous thromboembolism (VTE). But Opill contains only norgestrel, a form of progestin, which is not associated with thrombosis. Patients may be more likely to overestimate their potential risks for VTE than to underestimate them, according to Kwuan Paruchabutr, DNP, president of National Association of Nurse Practitioners in Women’s Health and an assistant professor at Georgetown University in Washington, DC.

“This is a progesterone-only pill: The risk is relatively low” of VTE, Dr. Paruchabutr said.

Clinicians should also take special care with patients who are prescribed drugs for seizures, tuberculosis, HIV/AIDS, and pulmonary hypertension or who are taking supplements containing St John’s wort.

Patients in their childbearing years who take isotretinoin are already expected to use some form of birth control.

“All patients on isotretinoin must be registered in the iPLEDGE program, which mandates monthly contraception counseling and monthly pregnancy tests for persons of childbearing potential,” Terrence A. Cronin, Jr, MD, president of the American Academy of Dermatology, told news organization through email.

Dr. Oelschlager noted that many patients who take isotretinoin may benefit from taking a birth control pill containing estrogen, for which they will need a prescription. At least three pills have an FDA-approved indication for treating moderate acne, including Ortho Tri-Cyclen, Estrostep, and Yaz.

The FDA has posted consumer-friendly information about the OTC pill that clinicians can refer their patients to. For clinicians who want more information, ACOG released a practice advisory about the switch in status for this progestin-only pill.
 

The Cost

While federal laws mandate employer-based and Medicaid plans cover prescription birth control pills for free, the OTC version will carry a cost, according to A. Mark Fendrick, MD, director of the University of Michigan Center for Value-Based Insurance Design in Ann Arbor, Michigan. 

Seven states, including New Mexico and New York, already have laws in effect that require health plans to cover certain OTC contraceptives without a prescription, according to a tally kept by the nonprofit research organization KFF.

Dr. Fendrick said it would be helpful for health plans to offer coverage for the OTC pill without copays even if they are not required to do so.

Priced at about $20 a month, Opill “is likely out of reach for many of the individuals who would most benefit from an OTC option,” Dr. Fendrick told this news organization in an email.

The new pill may be utilized most by those who do not have health insurance or have low incomes and cannot afford to see a doctor for a prescription, according to Sally Rafie, PharmD, a pharmacist specialist at University of California San Diego Health and founder of the Birth Control Pharmacist.

The manufacturer’s suggested retail prices will be $19.99 for a 1-month supply and $49.99 for a 3-month supply. Dublin-based Perrigo said it plans to offer a cost-assistance program for the drug in the coming weeks for people who have low incomes and lack insurance.

The Diagnosis: Acquired Cutaneous Lymphangiectasia

Histopathology showed a cluster of widely ectatic, thin-walled lymphatic spaces immediately subjacent to the epidermis and flanked by an epidermal collarette (Figure, A). The vessels did not extend any further than the papillary dermis and were not accompanied by any notable inflammation (Figure, B). A single layer of bland endothelial cells lined each lymphatic space (Figure, C). A diagnosis of acquired cutaneous lymphangiectasia secondary to surgical and radiation treatment of breast cancer was made. Clinical monitoring was recommended, but no treatment was required unless symptoms arose. At 2-year follow-up, she continued to do well.

Acquired cutaneous lymphangiectasia is characterized by benign dilations of surface lymphatic vessels, likely resulting from disruption of the lymphatic system.¹ This finding most commonly occurs on the external genitalia following combined surgical and radiation treatment of malignancy, though in a minority of cases it is seen with surgical or radiation treatment alone.² Acquired cutaneous lymphangiectasia secondary to radical mastectomy for breast cancer was first reported in 1956 in a patient with persistent ipsilateral lymphadenopathy.³ The presentation in a patient with Cowden syndrome is rare. Cowden syndrome (also called PTEN hamartoma tumor syndrome) is a rare autosomal-dominant disorder caused by mutations in the tumor suppressor phosphatase and tensin homolog gene, PTEN. It is characterized by multiple hamartomas and substantially increased risk for breast, endometrial, and thyroid malignancy.⁴ In addition to breast cancer, our patient had a history of papillary thyroid carcinoma, cerebellar dysplastic gangliocytoma, and multiple cutaneous fibromas and angiolipomas.

A diagnosis of syringomas—benign tumors that arise from the intraepidermal aspect of eccrine sweat ducts— could be considered in the differential diagnosis. Cases of eruptive syringoma on the breast have been reported, but the biopsy would show a circumscribed proliferation of tadpole-shaped tubules comprised of secretory cells in a sclerotic stroma.5 Hidrocystomas are benign sweat gland cysts that present on the face, especially around the eyes, but rarely have been reported on the trunk, particularly the axillae.6 Although they clinically manifest as translucent papules, histopathology shows fluid-filled cysts lined by a layer of secretory columnar epithelium.7 Metastatic breast carcinoma was considered, given the patient’s history of breast cancer. Cutaneous metastases often are found on the chest wall but also can occur at distant sites. Histopathology can reveal various patterns, including islands of tumor cells with glandular formation or single files of cells infiltrating through dermal collagen.

Angiosarcoma also must be considered in the setting of any vasoformative proliferation arising on previously irradiated skin. Angiosarcomas can sometimes be well differentiated with paradoxically bland cytomorphology but characteristically have anastomosing vessels and infiltrative architecture, which were not identified in our patient. Other diagnostic features of angiosarcoma include endothelial nuclear atypia, multilayering, and mitoses. Radiation-associated angiosarcomas amplify MYC, a transcription factor that affects multiple aspects of the cell cycle and is an oncogene implicated in several different types of malignancy.⁸ MYC immunohistochemistry testing should be performed whenever a vasoformative proliferation on irradiated skin is partially sampled or shows any features concerning for angiosarcoma. Lastly, the term postradiation atypical vascular lesion has been introduced to describe discrete papular proliferations that show close histopathologic overlap with lymphangioma/lymphatic malformations. In contrast, atypical vascular lesions show wedge-shaped intradermal growth that can cause diagnostic confusion with well-differentiated angiosarcoma. Unlike angiosarcomas, they do not express MYC. Postradiation atypical vascular lesions sometimes have an associated inflammatory infiltrate.⁹ Considerable histomorphologic overlap among lymphangiomas, atypical vascular lesions, and well-differentiated angiosarcomas exists; thus, lesions should be removed in their perceived totality whenever possible to help permit diagnostic distinction. In our patient, the abrupt discontinuation of vessels at the interface of the papillary and reticular dermis was reassuring of benignancy.

Our patient’s diagnosis of acquired cutaneous lymphangiectasia was a benign adverse effect of prior breast cancer treatments. This case demonstrates a rare dermatologic sequela that may arise in patients who receive surgical or radiation treatment of breast cancer. Given the heightened risk for angiosarcoma after radiation therapy as well as the increased risk for malignancy in patients with Cowden syndrome, biopsy can be an important diagnostic step in the management of these patients.

Angiosarcomas can sometimes be well differentiated with paradoxically bland cytomorphology but characteristically have anastomosing vessels and infiltrative architecture, which were not identified in our patient. Other diagnostic features of angiosarcoma include endothelial nuclear atypia, multilayering, and mitoses. Radiation-associated angiosarcomas amplify MYC, a transcription factor that affects multiple aspects of the cell cycle and is an oncogene implicated in several different types of malignancy.⁸ MYC immunohistochemistry testing should be performed whenever a vasoformative proliferation on irradiated skin is partially sampled or shows any features concerning for angiosarcoma. Lastly, the term postradiation atypical vascular lesion has been introduced to describe discrete papular proliferations that show close histopathologic overlap with lymphangioma/lymphatic malformations. In contrast, atypical vascular lesions show wedge-shaped intradermal growth that can cause diagnostic confusion with well-differentiated angiosarcoma. Unlike angiosarcomas, they do not express MYC. Postradiation atypical vascular lesions sometimes have an associated inflammatory infiltrate.⁹ Considerable histomorphologic overlap among lymphangiomas, atypical vascular lesions, and well-differentiated angiosarcomas exists; thus, lesions should be removed in their perceived totality whenever possible to help permit diagnostic distinction. In our patient, the abrupt discontinuation of vessels at the interface of the papillary and reticular dermis was reassuring of benignancy.

Our patient’s diagnosis of acquired cutaneous lymphangiectasia was a benign adverse effect of prior breast cancer treatments. This case demonstrates a rare dermatologic sequela that may arise in patients who receive surgical or radiation treatment of breast cancer. Given the heightened risk for angiosarcoma after radiation therapy as well as the increased risk for malignancy in patients with Cowden syndrome, biopsy can be an important diagnostic step in the management of these patients.

The Diagnosis: Acquired Cutaneous Lymphangiectasia

Histopathology showed a cluster of widely ectatic, thin-walled lymphatic spaces immediately subjacent to the epidermis and flanked by an epidermal collarette (Figure, A). The vessels did not extend any further than the papillary dermis and were not accompanied by any notable inflammation (Figure, B). A single layer of bland endothelial cells lined each lymphatic space (Figure, C). A diagnosis of acquired cutaneous lymphangiectasia secondary to surgical and radiation treatment of breast cancer was made. Clinical monitoring was recommended, but no treatment was required unless symptoms arose. At 2-year follow-up, she continued to do well.

Acquired cutaneous lymphangiectasia is characterized by benign dilations of surface lymphatic vessels, likely resulting from disruption of the lymphatic system.¹ This finding most commonly occurs on the external genitalia following combined surgical and radiation treatment of malignancy, though in a minority of cases it is seen with surgical or radiation treatment alone.² Acquired cutaneous lymphangiectasia secondary to radical mastectomy for breast cancer was first reported in 1956 in a patient with persistent ipsilateral lymphadenopathy.³ The presentation in a patient with Cowden syndrome is rare. Cowden syndrome (also called PTEN hamartoma tumor syndrome) is a rare autosomal-dominant disorder caused by mutations in the tumor suppressor phosphatase and tensin homolog gene, PTEN. It is characterized by multiple hamartomas and substantially increased risk for breast, endometrial, and thyroid malignancy.⁴ In addition to breast cancer, our patient had a history of papillary thyroid carcinoma, cerebellar dysplastic gangliocytoma, and multiple cutaneous fibromas and angiolipomas.

A diagnosis of syringomas—benign tumors that arise from the intraepidermal aspect of eccrine sweat ducts— could be considered in the differential diagnosis. Cases of eruptive syringoma on the breast have been reported, but the biopsy would show a circumscribed proliferation of tadpole-shaped tubules comprised of secretory cells in a sclerotic stroma.5 Hidrocystomas are benign sweat gland cysts that present on the face, especially around the eyes, but rarely have been reported on the trunk, particularly the axillae.6 Although they clinically manifest as translucent papules, histopathology shows fluid-filled cysts lined by a layer of secretory columnar epithelium.7 Metastatic breast carcinoma was considered, given the patient’s history of breast cancer. Cutaneous metastases often are found on the chest wall but also can occur at distant sites. Histopathology can reveal various patterns, including islands of tumor cells with glandular formation or single files of cells infiltrating through dermal collagen.

Angiosarcoma also must be considered in the setting of any vasoformative proliferation arising on previously irradiated skin. Angiosarcomas can sometimes be well differentiated with paradoxically bland cytomorphology but characteristically have anastomosing vessels and infiltrative architecture, which were not identified in our patient. Other diagnostic features of angiosarcoma include endothelial nuclear atypia, multilayering, and mitoses. Radiation-associated angiosarcomas amplify MYC, a transcription factor that affects multiple aspects of the cell cycle and is an oncogene implicated in several different types of malignancy.⁸ MYC immunohistochemistry testing should be performed whenever a vasoformative proliferation on irradiated skin is partially sampled or shows any features concerning for angiosarcoma.

Adding an immune checkpoint inhibitor to platinum-based chemotherapy resulted in a more than 1-year gain in median overall survival for women with primary advanced or recurrent endometrial cancer.

The benefit of the combination of the programmed death protein 1 (PD-1) inhibitor dostarlimab (Jemperli) and chemotherapy was even more pronounced among patients with DNA mismatch repair deficient/microsatellite instability high (dMMR/MSI-H) tumors.

These results, from the second interim analysis of the phase 3 ENGOT-EN6-NSGO/GOG-3031/RUBY trial, were cheered by audience members when they were reported at the Society of Gynecologic Oncology (SGO)’s Annual Meeting on Women’s Cancer, held in San Diego, California.

“Overall survival benefit to the addition of PD-1 inhibitor to chemotherapy upfront for patients with advanced and recurrent MSI-high endometrial cancer: SOLD!” said invited discussant Gini Fleming, medical director of gynecologic oncology at the University of Chicago.

“I think this is a huge win for our patients. It’s something that none of us have seen before over many years of working with endometrial cancer and should be incorporated into everybody’s practice as of yesterday,” she said.

Continued Improvement

Results from the first interim analysis of the trial showed that dostarlimab and chemotherapy significantly improved progression-free survival (PFS) in the dMMR/MSI-H population, and there was an early trend toward improved overall survival, compared with chemotherapy plus placebo.

As Matthew A. Powell, MD from Washington University School of Medicine in Saint Louis, Missouri reported at SGO 2024, that early trend has become an undeniable survival advantage.

At a median follow-up of 37.2 months, the median overall survival was 44.6 months for patients randomized to the combination, compared with 28.2 months for those assigned to chemotherapy plus placebo.

The respective 3-year overall survival (OS) rates were 54.9% and 42.9%, translating into a hazard ratio (HR) for death with dostarlimab/chemotherapy of 0.69 (P = .002).

Among the subset of patients with dMMR/MSI-H tumors the survival benefit conferred by the combination was even greater, with median OS not reached in the dostarlimab group vs 31.4 months in the chemotherapy-alone arm, with respective 3-year OS rates of 78% and 46%. This difference translated into a HR for death with the combination of 0.32 (P = .0002) for patients with deficient mismatch-repair cancers.

“Dostarlimab plus carboplatin-paclitaxel chemotherapy demonstrated statistically significant and clinically meaningful overall survival improvements in the overall population, a substantial unprecedented overall survival benefit in patients with defective mismatch-repair tumors, and a clinically meaningful; 7-month improvement in the OS difference in patients with proficient mismatch-repair tumors,” Dr. Powell said.

RUBY Details

The trial was conducted in 494 patients with primary advanced stage III or IV or first recurrent endometrial cancer who received first-line treatment with standard chemotherapy with carboplatin (area under the concentration–time curve, 5 mg/mL per minute) and paclitaxel (175 mg/m² of body surface area), every 3 weeks (six cycles). They were also randomized to receive either dostarlimab (1000 mg) or dostarlimab placebo every 6 weeks for up to 3 years.

Within the cohort, 118 patients (23.9%) had dMMR/MSI-H tumors.

At the time of the first interim analysis the estimated progression-free survival at 24 months in the dMMR–MSI-H subgroup was 61.4% in the dostarlimab group vs 15.7 in the placebo group (HR for progression or death, 0.28; P < .001). For the entire cohort, progression-free survival at 24 months was 36.1% vs 18.1% (HR, 0.64; P < .001).

A prespecified exploratory analysis of progression-free survival in proficient MMR, microsatellite stable (MSS) patients was also done, and a clinically relevant benefit was observed.

Overall survival at that time also favored dostarlimab, although it was only mature for 33% of the population. But at 24 months, OS rates were 71.3% vs 56.0% among placebo recipients; this difference approached but did not reach statistical significance.

The overall response rate in the dMMR–MSI-H population vs the placebo group was 77.6% vs 69%, respectively, and 68.1% and 63.4% in the pMMR/MSS population.

The most common adverse events observed were nausea, alopecia, and fatigue. Grade 3 and higher adverse events at the most recent follow-up were more frequent in the dostarlimab group than in the placebo group (72.2% vs 60.2%).

“Importantly, safety was maintained” at the second interim analysis, Dr. Powell said.

“No new safety signals were noted, no new deaths related to therapy were noted with the subsequent 1-year additional analysis time,” he said.

What’s Next?

Dr. Fleming reviewed potential strategies for further improving care of patients with advanced or recurrent endometrial cancer during her discussion.

“What are the next directions for patients with MSI-high disease? Well, obviously could we use immune checkpoint inhibitors without chemotherapy and not compromise results? There are two ongoing trials or trials that we’re awaiting results of that have compared single-agent immune checkpoint inhibitor to just chemotherapy in mismatch repair-deficient advanced disease, and hopefully we can extrapolate from these trials to determine if this might be a more patient-friendly and equally effective strategy, but we don’t yet know,” she said.

Dr. Fleming also noted that ongoing or planned clinical trials will address questions about potential options for patients with MSI-H tumors whose disease progresses on frontline chemotherapy and immunotherapy. Other trials are assessing whether combining radiotherapy with checkpoint inhibitors will be effective in treating patients with earlier-stage tumors, or whether the addition of a PARP inhibitor might offer additional benefit for these patients.

“Immune checkpoint inhibitor should be given first line to patients with advanced/recurrent microsatellite [instability] endometrial cancer, and they should be considered as front line in patients with microsatellite stable disease. At this point, unfortunately, we have no reasonable predictive factors to know which of those patients with microsatellite stable disease will truly benefit. Multiple other agents are being tested in this setting, and will hopefully prove useful in subgroups,” she said.

The study is funded by GlaxoSmithKline. Dr. Powell reports grants/research support from GSK and honoraria/consultation fees from AstraZeneca, Clovis Oncology, Eisai, GSK, Immunogen, and Merck. Dr. Fleming reports serving as an institutional principal investigator for trials sponsored by multiple companies, not including GSK.

SAN DIEGO — In published trials, both an interleukin (IL)–17 inhibitor and an IL-23 inhibitor achieved impressive rates of clear or almost clear responses in patients with moderate to severe plaque psoriasis, but late-breaker data presented at the annual meeting of the American Academy of Dermatology show that these types of responses are sustained for as long as patients have remained on therapy.

Of the two, the longer follow up is with the IL-17 inhibitor bimekizumab (Bimzelx). In a 4-year open-label extension study, the Psoriasis Area and Severity Index (PASI) 90 rate was approximately 85% in treated patients, according to Mark Lebwohl, MD, professor and chairman emeritus of the Department of Dermatology, Icahn School of Medicine at Mount Sinai in New York City

A PASI 90 score signifies that 90% of skin surface area is cleared. The proportion of patients who achieved a PASI 100 score, signifying total clearance, approached 70% at 4 years in the group with the greatest response. PASI 90 and PASI 100 rates at this point were only modestly lower than those reported at the end of the double-blind phase 3 trial when evaluated 3 years earlier. 

Follow-up with a novel oral anti-IL-23 inhibitor JNJ-2113 (JNJ-77242113) was only 52 weeks, far shorter. But again, the response for the most effective dose at the end of this period was essentially unchanged from that at 16 weeks. Among those on the highest and most effective test dose of once-daily 100 mg, the PASI 90 at 1 year was 64.3%, a rate that was essentially unchanged from week 16.

No Apparent Loss of Benefit Over Time

“We can really look at those dose-response curves and see that there is, overall, a maintenance of response,” reported Laura K. Ferris, MD, PhD, professor and director of clinical trials, Department of Dermatology, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania. In her presentation of the data, she showed similar sustained control for the most effective doses of JNJ-2113 for multiple clinical outcomes, including an investigator’s global assessment (IGA) score of 0 or 1, also signifying clear or near clear skin.

Bimekizumab, a monoclonal antibody that inhibits both IL-17A and IL-17F, is already approved for the treatment of plaque psoriasis. The 52-week BE SURE trial, which provided the 478 patients who entered into the BE BRIGHT open label extension study, was published in The New England Journal of Medicine in July 2021. 

In the 4-year data reported by Dr. Lebwohl, three groups were compared: Those initially randomized to an every-4-week dosing schedule of bimekizumab over the course of the 52-week BE SURE trial; those randomized to an every-4-week bimekizumab schedule who were then subsequently switched to an every-8-week schedule; and those initiated on the TNF-inhibitor adalimumab (Humira) and were then switched at week 24 to every-4-week bimekizumab.

The PASI 90 responses at 52 weeks in these three groups, respectively, were 91.2%, 89.3%, and 95.2%. At 4 years, this almost clear response was observed in 82.4%, 83.2%, and 87.6%, respectively. At 52 weeks, the PASI 100 responses in these three groups, respectively, were 75.3%, 74.2%, and 72.9%. At 4 years, 61.9%, 58.5%, and 69.5% still had complete skin clearance.

Bimekizumab was well tolerated during the randomized trial, reported Dr. Lebwohl. The rates of nasopharyngitis and oral candidiasis, which were observed in approximately 12% and 8%, respectively, of treated patients during the randomized phase remained at about the same level in the long-term follow up. There were no new safety signals, he said.
 

JNJ-2113 Is First Potential Oral IL-23 Inhibitor

JNJ-2113 is a first-in-class oral peptide that binds to the IL-23 receptor, blocking the IL-23 signaling pathway. If approved, it would be the first oral therapy targeting IL-23. The 16-week outcomes of the dose-finding FRONTIER 1 phase 2b trial were published in The New England Journal of Medicine earlier this year. The primary endpoint was PASI 75, achieved by 79% of those on the 100 mg twice daily dose at week 16, vs 9% on placebo, and at 52 weeks, was 76%. 

“The proportion of patients achieving the FRONTIER 1 primary endpoint was maintained from week 16 to the end of week 52 in the extension study,” Dr. Ferris said, but further pointed out that rates of near or complete clearance achieved at week 16 were also essentially unchanged at week 52. This was true of PASI scores and IGA. 

Clearance of psoriatic lesions on the scalp was particularly impressive. By scalp-specific IGA, rates of clear or near clear (0/1) were not just maintained but improved over the course of follow-up, reaching 75.1% at 52 weeks in the highest dose group, she said.

JNJ-2113 was well tolerated in FRONTIER 1 and remained so during long-term follow-up, in the FRONTIER 2 extension study, according to Dr. Ferris. The most common complaints with JNJ-2113, such as nasopharyngitis (18.1% vs 25.7% in placebo), did not appear to differ significantly from placebo and the treatment remained well tolerated over the course of the extended follow-up.

There are limited direct comparisons of different biologics active in the treatment of plaque psoriasis for efficacy and safety, but these data appear to show a depth and durability of benefit for psoriasis that is exceptional, Dr. Lebwohl told this news organization. “The PASI 100 scores achieved by bimekizumab exceed anything we have seen to date,” he said. “And the durability of those exceedingly high scores is remarkable.”

Dr. Lebwohl reports financial relationships with approximately 40 pharmaceutical companies, including UCB Pharma, which developed bimekizumab. Dr. Ferris reports financial relationships with more than 20 pharmaceutical companies, including Janssen, which is developing JNJ-2113.

In her presentation of the data, she showed similar sustained control for the most effective doses of JNJ-2113 for multiple clinical outcomes, including an investigator’s global assessment (IGA) score of 0 or 1, also signifying clear or near clear skin.

Bimekizumab, a monoclonal antibody that inhibits both IL-17A and IL-17F, is already approved for the treatment of plaque psoriasis. The 52-week BE SURE trial, which provided the 478 patients who entered into the BE BRIGHT open label extension study, was published in The New England Journal of Medicine in July 2021. 

In the 4-year data reported by Dr. Lebwohl, three groups were compared: Those initially randomized to an every-4-week dosing schedule of bimekizumab over the course of the 52-week BE SURE trial; those randomized to an every-4-week bimekizumab schedule who were then subsequently switched to an every-8-week schedule; and those initiated on the TNF-inhibitor adalimumab (Humira) and were then switched at week 24 to every-4-week bimekizumab.

The PASI 90 responses at 52 weeks in these three groups, respectively, were 91.2%, 89.3%, and 95.2%. At 4 years, this almost clear response was observed in 82.4%, 83.2%, and 87.6%, respectively. At 52 weeks, the PASI 100 responses in these three groups, respectively, were 75.3%, 74.2%, and 72.9%. At 4 years, 61.9%, 58.5%, and 69.5% still had complete skin clearance.

Bimekizumab was well tolerated during the randomized trial, reported Dr. Lebwohl. The rates of nasopharyngitis and oral candidiasis, which were observed in approximately 12% and 8%, respectively, of treated patients during the randomized phase remained at about the same level in the long-term follow up. There were no new safety signals, he said.
 

JNJ-2113 Is First Potential Oral IL-23 Inhibitor

JNJ-2113 is a first-in-class oral peptide that binds to the IL-23 receptor, blocking the IL-23 signaling pathway. If approved, it would be the first oral therapy targeting IL-23. The 16-week outcomes of the dose-finding FRONTIER 1 phase 2b trial were published in The New England Journal of Medicine earlier this year. The primary endpoint was PASI 75, achieved by 79% of those on the 100 mg twice daily dose at week 16, vs 9% on placebo, and at 52 weeks, was 76%. 

“The proportion of patients achieving the FRONTIER 1 primary endpoint was maintained from week 16 to the end of week 52 in the extension study,” Dr. Ferris said, but further pointed out that rates of near or complete clearance achieved at week 16 were also essentially unchanged at week 52. This was true of PASI scores and IGA. 

Clearance of psoriatic lesions on the scalp was particularly impressive. By scalp-specific IGA, rates of clear or near clear (0/1) were not just maintained but improved over the course of follow-up, reaching 75.1% at 52 weeks in the highest dose group, she said.

JNJ-2113 was well tolerated in FRONTIER 1 and remained so during long-term follow-up, in the FRONTIER 2 extension study, according to Dr. Ferris. The most common complaints with JNJ-2113, such as nasopharyngitis (18.1% vs 25.7% in placebo), did not appear to differ significantly from placebo and the treatment remained well tolerated over the course of the extended follow-up.

There are limited direct comparisons of different biologics active in the treatment of plaque psoriasis for efficacy and safety, but these data appear to show a depth and durability of benefit for psoriasis that is exceptional, Dr. Lebwohl told this news organization. “The PASI 100 scores achieved by bimekizumab exceed anything we have seen to date,” he said. “And the durability of those exceedingly high scores is remarkable.”

Dr. Lebwohl reports financial relationships with approximately 40 pharmaceutical companies, including UCB Pharma, which developed bimekizumab. Dr. Ferris reports financial relationships with more than 20 pharmaceutical companies, including Janssen, which is developing JNJ-2113.

SAN DIEGO — In published trials, both an interleukin (IL)–17 inhibitor and an IL-23 inhibitor achieved impressive rates of clear or almost clear responses in patients with moderate to severe plaque psoriasis, but late-breaker data presented at the annual meeting of the American Academy of Dermatology show that these types of responses are sustained for as long as patients have remained on therapy.

Of the two, the longer follow up is with the IL-17 inhibitor bimekizumab (Bimzelx). In a 4-year open-label extension study, the Psoriasis Area and Severity Index (PASI) 90 rate was approximately 85% in treated patients, according to Mark Lebwohl, MD, professor and chairman emeritus of the Department of Dermatology, Icahn School of Medicine at Mount Sinai in New York City

A PASI 90 score signifies that 90% of skin surface area is cleared. The proportion of patients who achieved a PASI 100 score, signifying total clearance, approached 70% at 4 years in the group with the greatest response. PASI 90 and PASI 100 rates at this point were only modestly lower than those reported at the end of the double-blind phase 3 trial when evaluated 3 years earlier. 

Follow-up with a novel oral anti-IL-23 inhibitor JNJ-2113 (JNJ-77242113) was only 52 weeks, far shorter. But again, the response for the most effective dose at the end of this period was essentially unchanged from that at 16 weeks. Among those on the highest and most effective test dose of once-daily 100 mg, the PASI 90 at 1 year was 64.3%, a rate that was essentially unchanged from week 16.

No Apparent Loss of Benefit Over Time

“We can really look at those dose-response curves and see that there is, overall, a maintenance of response,” reported Laura K. Ferris, MD, PhD, professor and director of clinical trials, Department of Dermatology, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania. In her presentation of the data, she showed similar sustained control for the most effective doses of JNJ-2113 for multiple clinical outcomes, including an investigator’s global assessment (IGA) score of 0 or 1, also signifying clear or near clear skin.

There are over 3700 types of mosquitoes worldwide and over 200 types in the continental United States, of which only 12 are associated with transmitting diseases to humans. The majority are just a nuisance. Since they cannot readily be distinguished, strategies to prevent any bites are recommended.

West Nile Virus

In the US, West Nile virus (WNV) is the leading cause of neuroinvasive arboviral disease. Just hearing the name took me back to New York in 1999 when sightings of dead birds around the city and boroughs were reported daily. The virus was isolated that same year. The enzootic circle occurs between mosquitoes and birds, which are the primary vertebrate host via the bite of Culex mosquitoes. After a bite from an infected mosquito, humans are usually a dead-end host since the level and duration of viremia needed to infect another mosquito is insufficient.

Human-to-human transmission is documented through blood transfusion and solid organ transplantation. Vertical transmission is rarely described. Initially isolated in New York, WNV quickly spread across North America and has been isolated in every continent except Antarctica. Most cases occur in the summer and autumn.

Most infected individuals are asymptomatic. Those who do develop symptoms have fever, headache, myalgia, arthralgia, nausea, vomiting, and a transient rash. Less than 1% develop meningitis/encephalitis symptoms similar to other causes of aseptic meningitis. Those with encephalitis in addition to fever and headache may have altered mental status and focal neurologic deficits including flaccid paralysis or movement disorders.

Detection of anti-WNV IgM antibodies (AB) in serum or CSF is the most common way to make the diagnosis. IgM AB usually is present within 3-8 days after onset of symptoms and persists up to 90 days. Data from ArboNET, the national arboviral surveillance system managed by Centers for Disease Control and Prevention and state health departments, reveal that from 1999 to 2022 there were 56,575 cases of WNV including 28,684 cases of neuroinvasive disease. In 2023 there were 2,406 and 1,599 cases, respectively. Those historic totals for WNV are 10 times greater than the totals for all the other etiologies of neuroinvasive arboviral diseases in the US combined (Jamestown Canyon, LaCrosse, St. Louis, and Eastern Equine encephalitis n = 1813).

Remember to include WNV in your differential of a febrile patient with neurologic symptoms, mosquito bites, blood transfusions, and organ transplantation. Treatment is supportive care.

The US began screening all blood donations for WNV in 2003. Organ donor screening is not universal.

Dengue

Dengue, another arbovirus, is transmitted by bites of infected Aedes aegypti and Aedes albopictus mosquitoes, which prefer to feed during the daytime. There are four dengue virus serotypes: DENV-1 DENV-2, DENV-3 and DENV-4. In endemic areas, all four serotypes are usually co-circulating and people can be infected by each one.

Long-term immunity is type specific. Heterologous protection lasts only a few months. Dengue is endemic throughout the tropics and subtropics of Asia, Africa, and the Americas. Approximately 53% of the world’s population live in an area where dengue transmission can occur. In the US, most cases are reported from Puerto Rico. Dengue is endemic in the following US territories: Puerto Rico, US Virgin Islands, American Samoa, and free associated states. Most cases reported on the mainland are travel related. However, locally acquired dengue has been reported. From 2010 to 2023 Hawaii reported 250 cases, Florida 438, and Texas 40 locally acquired cases. During that same period, Puerto Rico reported more than 32,000 cases. It is the leading cause of febrile illness for travelers returning from the Caribbean, Latin America, and South Asia. Peru is currently experiencing an outbreak with more than 25,000 cases reported since January 2024. Most cases of dengue occur in adolescents and young adults. Severe disease occurs most often in infants, those with underlying chronic disease, pregnant women, and persons infected with dengue for the second time.

Symptoms range from a mild febrile illness to severe disease associated with hemorrhage and shock. Onset is usually 7-10 days after infection and symptoms include high fever, severe headache, retro-orbital pain, arthralgia and myalgias, nausea, and vomiting; some may develop a generalized rash.

The World Health Organization (WHO) classifies dengue as 1) dengue with or without warning signs for progression of disease and 2) severe dengue. Warning signs for disease progression include abdominal pain or tenderness, persistent vomiting, fluid accumulation (e.g., ascites, pericardial or pleural effusion), mucosal bleeding, restlessness, postural hypotension, liver enlargement greater than 2 cm. Severe dengue is defined as any sign of severe plasma leakage leading to shock, severe bleeding or organ failure, or fluid accumulation with respiratory distress. Management is supportive care.

Prevention: In the US, Dengvaxia, a live attenuated tetravalent vaccine, is approved for use in children aged 9–16 years with laboratory-confirmed previous dengue virus infection and living in areas where dengue is endemic. It is administered at 0, 6, and 12 months. It is not available for purchase on the mainland. Continued control of the vector and personal protection is necessary to prevent recurrent infections.
 

CHIKV

Chikungunya (CHIKV), which means “that which bends up” in the Mkonde language of Tanzania, refers to the appearance of the person with severe usually symmetric arthralgias characteristic for this infection that otherwise is often clinically confused with dengue and Zika. It too is transmitted by A. aegypti and A. albopictus and is prevalent in tropical Africa, Asia, Central and South America, and the Caribbean. Like dengue it is predominantly an urban disease. The WHO reported the first case in the Western Hemisphere in Saint Martin in December 2013. By August 2014, 31 additional territories and Caribbean or South American countries reported 576,535 suspected cases. Florida first reported locally acquired CHIKV in June 2014. By December an additional 11 cases had been identified. Texas reported one case in 2015. Diagnosis is with IgM ab or PCR. Treatment is supportive with most recovering from acute illness within 2 weeks. Data in adults indicate 40-52% may develop chronic or recurrent joint pain.

Prevention: IXCHIQ, a live attenuated vaccine, was licensed in November 2023 and recommended by the CDC in February 2024 for use in persons at least 18 years of age with travel to destinations where there is a CHIKV outbreak. It may be considered for persons traveling to a country or territory without an outbreak but with evidence of CHIKV transmission among humans within the last 5 years and those staying in endemic areas for a cumulative period of at least 6 months over a 2-year period. Specific recommendations for lab workers and persons older than 65 years were also made. This is good news for your older patients who may be participating in mission trips, volunteering, studying abroad, or just vacationing in an endemic area. Adolescent vaccine trials are ongoing and pediatric trials will soon be initiated. In addition, vector control and use of personal protective measures cannot be emphasized enough.

There are several other mosquito borne diseases, however our discussion here is limited to three. Why these three? WNV as a reminder that it is the most common neuroinvasive agent in the US. Dengue and CHIKV because they are not endemic in the US so they might not routinely be considered in febrile patients; both diseases have been reported and acquired on the mainland and your patients may travel to an endemic area and return home with an unwanted souvenir. You will be ready for them.

Prevention: In the US, Dengvaxia, a live attenuated tetravalent vaccine, is approved for use in children aged 9–16 years with laboratory-confirmed previous dengue virus infection and living in areas where dengue is endemic. It is administered at 0, 6, and 12 months. It is not available for purchase on the mainland. Continued control of the vector and personal protection is necessary to prevent recurrent infections.
 

CHIKV

Chikungunya (CHIKV), which means “that which bends up” in the Mkonde language of Tanzania, refers to the appearance of the person with severe usually symmetric arthralgias characteristic for this infection that otherwise is often clinically confused with dengue and Zika. It too is transmitted by A. aegypti and A. albopictus and is prevalent in tropical Africa, Asia, Central and South America, and the Caribbean. Like dengue it is predominantly an urban disease. The WHO reported the first case in the Western Hemisphere in Saint Martin in December 2013. By August 2014, 31 additional territories and Caribbean or South American countries reported 576,535 suspected cases. Florida first reported locally acquired CHIKV in June 2014. By December an additional 11 cases had been identified. Texas reported one case in 2015. Diagnosis is with IgM ab or PCR. Treatment is supportive with most recovering from acute illness within 2 weeks. Data in adults indicate 40-52% may develop chronic or recurrent joint pain.

Prevention: IXCHIQ, a live attenuated vaccine, was licensed in November 2023 and recommended by the CDC in February 2024 for use in persons at least 18 years of age with travel to destinations where there is a CHIKV outbreak. It may be considered for persons traveling to a country or territory without an outbreak but with evidence of CHIKV transmission among humans within the last 5 years and those staying in endemic areas for a cumulative period of at least 6 months over a 2-year period. Specific recommendations for lab workers and persons older than 65 years were also made. This is good news for your older patients who may be participating in mission trips, volunteering, studying abroad, or just vacationing in an endemic area. Adolescent vaccine trials are ongoing and pediatric trials will soon be initiated. In addition, vector control and use of personal protective measures cannot be emphasized enough.

There are several other mosquito borne diseases, however our discussion here is limited to three. Why these three? WNV as a reminder that it is the most common neuroinvasive agent in the US. Dengue and CHIKV because they are not endemic in the US so they might not routinely be considered in febrile patients; both diseases have been reported and acquired on the mainland and your patients may travel to an endemic area and return home with an unwanted souvenir. You will be ready for them.

Silence Therapeutics shared positive topline 36-week data from its ongoing phase 2 study of zerlasiran, a long-acting agent directed at lowering Lp(a) levels. 

In a statement, the company said the study shows a highly significant reduction from baseline in Lp(a) levels with zerlasiran compared with placebo at 36 weeks, the primary endpoint.

Zerlasiran (formerly known as SLN360), is a short interfering RNA (siRNA) agent, or “ gene silencing” therapy. It binds to and temporarily blocks the action of the LPA gene which encodes for apolipoprotein(a), a dominant and a rate-limiting component in the hepatic synthesis of the Lp(a) particle.

A previous phase 1 study showed that single subcutaneous doses of the drug, ranging from 30 mg to 600 mg, produced a dose-dependent reduction in Lp(a) plasma levels at 45-60 days.

The current double-blind placebo-controlled phase 2 trial — known as ALPACAR-360 — enrolled 178 patients at high risk for atherosclerotic cardiovascular events who had elevated levels of Lp(a), ie, ≥ 125 nmol/L (median baseline Lp(a) was approximately 215 nmol/L). They were randomized to zerlasiran or placebo. 

Zerlasiran was administered at 300 mg subcutaneously every 16 or 24 weeks or at 450 mg every 24 weeks. 

Results reported by the company show a median percentage reduction in Lp(a) of ≥ 90% for both doses at week 36, with no new safety concerns identified during this treatment period.

The 60-week study is ongoing, and secondary endpoints, including change in Lp(a) from baseline to 48 weeks (end of treatment period) and 60 weeks (end of study) and potential effects on other lipids/lipoproteins, will be evaluated.

Silence says it plans to report topline 48-week data from the ALPACAR-360 study in the second quarter of this year.

Elevated levels of Lp(a) represent a genetic risk factor for cardiovascular disease, which is believed to affect approximately 20% of the population. Although there are currently no approved Lp(a)-lowering therapies, several drug candidates are in late-stage clinical testing.

A cell-free DNA (cfDNA) blood test, aimed at detecting abnormal DNA signals in people with an average risk of colorectal cancer (CRC), correctly detected CRC in most people confirmed to have the disease, according to a new study.

The cfDNA blood test had 83% sensitivity for CRC, 90% specificity for advanced neoplasia, and 13% sensitivity for advanced precancerous lesions. Other noninvasive screening methods have sensitivity from 67% to 94% for CRC and 22% to 43% for advanced precancerous lesions.

“The results of the study are a promising step toward developing more convenient tools to detect colorectal cancer early while it is more easily treated,” said senior author William M. Grady, MD, AGAF, medical director of the Gastrointestinal Cancer Prevention Program at the Fred Hutchinson Cancer Center in Seattle.

“The test, which has an accuracy rate for colon cancer detection similar to stool tests used for early detection of cancer, could offer an alternative for patients who may otherwise decline current screening options,” he said.

The study was published online on March 14 in The New England Journal of Medicine.
 

Analyzing the Blood Test’s Accuracy 

Dr. Grady and colleagues conducted a multisite clinical trial called ECLIPSE, which compared the sensitivity and specificity of a cfDNA blood test (Shield, Guardant Health) against that obtained with colonoscopy, the gold standard for CRC screening. Guardant led and funded the study.

Guardant’s Shield test is designed to detect CRC through genomic alterations, aberrant methylation status, and fragmentomic patterns, which show up as an “abnormal signal detected” result. Similar blood tests are being developed as “liquid biopsy” tests for other emerging cancer screenings as well.

The study included 7861 people with average CRC risk who underwent routine screening with colonoscopy at 265 sites in the United States, including primary care and endoscopy centers in academic and community-based institutions. Eligible people were aged 45-84 years (average age, 60 years), and 53.7% were women. The race and ethnicity characteristics of the participants closely mirrored the demographic distribution in the 2020 US Census.

Overall, 54 of 65 (83.1%) participants with colonoscopy-detected CRC had a positive cfDNA blood test. However, 11 participants (16.9%) with CRC had a negative test.

The cfDNA blood test identified 42 of 48 stage I, II, or III CRCs, indicating a sensitivity of 87.5%, including 65% for stage I cancers, 100% for stage II cancers, and 100% for stage III cancers. The test also identified all 10 of the stage IV CRC cases. There were no substantial differences in sensitivity for CRC based on primary tumor location, tumor histologic grade, or demographic characteristics.

Among participants without advanced colorectal neoplasia on colonoscopy, 89.6% had a negative cfDNA blood test, and 10.4% had a positive test. 

Among those with a negative colonoscopy — with no CRC, advanced precancerous lesions, or nonadvanced precancerous lesions — specificity was 89.9%.

Among 1116 participants with advanced precancerous lesions identified as the most advanced lesion on colonoscopy, the cfDNA blood test was positive for 147, indicating a sensitivity for advanced precancerous lesions of 13.2%.

Although the blood test has sensitivity similar to stool-based tests for CRC, the accuracy is lower than it is with colonoscopy, which remains the current gold standard for CRC screening, Dr. Grady said.

“Colorectal cancer is common and very preventable with screening, but only about 50% to 60% of people who are eligible for screening actually take those tests,” he said. “Getting people to be screened for cancer works best when we offer them screening options and then let them choose what works best for them.”
 

Future Research

Colorectal cancer is the second leading cause of cancer-related death among US adults and is now the third most diagnosed cancer for people younger than 50 years, Dr. Grady said. Although overall CRC death rates have declined in recent years, the rates among those younger than 55 years have increased since the mid-2000s.

“When colorectal cancer is found earlier and the cancer has not yet spread throughout the body, patient outcomes are much better, as reflected in 5-year survival being much better. It makes sense that an effective blood-based test could have a potential role, in particular for those not getting screened yet,” said Joshua Melson, MD, AGAF, clinical professor of medicine and director of the High-Risk Clinic for Gastrointestinal Cancers at the University of Arizona Cancer Center in Tucson.

Dr. Melson, who wasn’t involved with this study, noted that blood-based testing shows promise for cancer detection but needs additional support for real-world implementation. For instance, the Shield blood test has difficulty detecting precancerous lesions, and it remains unclear what the optimal intervals for repeat testing would be after a negative test, he said. In addition, screening programs will need to ensure they have capacity to effectively deal with a positive test result.

“For a screening program to actually work, when a noninvasive test (whether blood-based or stool-based) is read as positive, those patients need to have a follow-up colonoscopy,” he said. 

Proper communication with patients will be important as well, said Gloria Coronado, PhD, associate director of Population Sciences at the University of Arizona Cancer Center, Tucson. Dr. Coronado, who wasn’t involved with this study, has developed CRC screening messages for specific patient populations and studied patient reactions to CRC blood tests. 

In a study by Dr. Coronado and colleagues, among more than 2000 patients who passively declined fecal testing and had an upcoming clinic visit, CRC screening proportions were 17.5 percentage points higher in the group offered the blood test vs those offered usual care. In qualitative interviews, one patient said of the blood-based testing option, “I was screaming hallelujah!”

“Patients believed that a blood test would be more accurate than a stool-based test. However, for the detection of advanced adenomas, the reverse is true,” she said. “It will be important to balance the high acceptance and enthusiasm for the blood test with the lower performance of the blood test compared to other tests already on the market.”

In a statement accompanying the study’s publication, the American Gastroenterological Association welcomed these results as an exciting development, but cautioned that a blood-based test was not interchangeable with colonoscopy.

“The Centers for Medicare and Medicaid Services (CMS) has determined it will cover a blood test for colorectal cancer screening every three years if the test achieves 74% sensitivity for CRC, 90% specificity, and FDA approval,” the statement reads. “However, a blood test that meets only the CMS criteria will be inferior to current recommended tests and should not be recommended to replace current tests. Such a test could be recommended for patients who decline all other recommended tests, since any screening is better than no screening at all.”

Dr. Grady is a paid member of Guardant’s scientific advisory board and advised on the design and procedure of the clinical trial and data analysis. Dr. Melson previously served as consultant for Guardant. Dr. Coronado reported no relevant disclosures.
