Reduced Vaccination Rates Contribute to Rising Pertussis Numbers
New data from the Centers for Disease Control and Prevention (CDC) show significant spikes in pertussis cases compared with last year, especially in several urban areas including New York, Illinois, Florida, and Colorado.
Notably, the current pertussis case count in Illinois as of September 21, 2024, was five times higher than the total cases in 2023 (1058 vs 50). New York City alone had reported 624 cases as of September 21, compared with 38 cases in 2023.
Additional data from the CDC on vaccination coverage and exemptions of school-aged children showed an increase from 3.0% last year to 3.3% in 2024 of children who were exempted from recommended vaccination requirements. Although nearly 93% of kindergarteners in the United States received recommended vaccines (including Tdap), similar to last year, this number shows a steady decline from 94% in the 2021-2021 school year and 93% in the 2021-2022 school year, according to previous CDC reports.
What’s Happening in the Clinic
Clinical experience and the most recent CDC data point to under vaccination as a driver of the increased pertussis cases this year, David J. Cennimo, MD, associate professor of medicine and pediatrics in the division of infectious disease at Rutgers New Jersey Medical School, Newark, New Jersey, said in an interview.
Although the pertussis vaccination rates in infancy are still very good, clinicians are seeing a drop-off in school-aged children and adults, and the lingering anti-vaccine efforts from the COVID-19 pandemic period are undoubtedly playing a part, said Dr. Cennimo. “Unfortunately, pertussis is contagious, and the vaccine effectiveness wears off. Having decreased numbers of people protected results in more rapid spread,” he said.
Dr. Cennimo agreed that the number of cases in the United States is underreported, and even higher than the data suggest. “I’m sure of it; the initial clinical presentation may be mistaken for a viral upper respiratory tract infection (common cold),” he told this news organization.
Many older children and adults with pertussis do not manifest the classic “whooping cough” seen in infants and young children, so making a clinical diagnosis can be difficult, he said. “One classical component of the illness is a prolonged cough. I have wondered if some people now reporting a lingering cough had pertussis that was missed,” Dr. Cennimo noted.
“Clinicians should stress the value of boosters in a vaccine-preventable illness where we know immunity wanes overtime,” Dr. Cennimo said. “We have a great remedy in the Tdap vaccine, which we should all be getting very 10 years,” he said.
He also emphasized that clinicians remind pregnant women of the current recommendations to receive the Tdap vaccine for every pregnancy. “Vaccination during pregnancy is the best way to protect both the pregnant person and the newborn.
Even for the vaccine hesitant, this vaccine has a long track record of safety so should not be a significant concern,” he said.
The ultimate take-home message is not a new one, and applies to all illnesses, Dr. Cennimo told this news organization. Simply put, “Stay home if you are sick. Social distancing is not just for COVID-19,” he said.
Dr. Cennimo had no financial conflicts to disclose.

Public Health, Not Politics, Should Drive Mask Policies, Says Ethicist
This transcript has been edited for clarity.
I recently saw a ban that has me very worried, concerned, and strongly in opposition.
Basically, the standard kind of medical mask would be captured, although I think their aim in doing this was to try to discourage people at political protests from being able to wear masks and hide their identity. They’re basically trying to discourage that. This is particularly triggered by, I think, protests about the invasion of Israel, the war that resulted in Gaza, and the demonstrations that have gone on around the country, with many people masked.
There may be issues about what is acceptable to wear when you go to a demonstration. I don’t claim to know about the civil rights of that.
In a time at which COVID-19 is flourishing, really on the rebound, expanding fast, and still causing 600 deaths a week; the flu season is going to be upon us soon enough; and there are also concerns about the possibility of avian flu jumping into the human population, it is absolutely the wrong time to single out those who are trying to mask for health reasons.
Basically, there are two strong reasons. One, there are people out there who wear a medical mask or mask for a medical reason because they have an underlying disease. They may have had a transplant or they may feel they’re immunocompromised for some reason. They worry that, if they don’t wear a mask, they’re going to get an infection from something like COVID-19 or flu, which could really be super-dangerous for them.
The other reason people mask is to protect their family members. They may have someone who’s immunocompromised in the family, or they’re doing it kindly and altruistically to protect the rest of us and to stop viruses from circulating.
These bans are not taking into account public health. They’re being brought forward in the midst of political heat about demonstrations and political issues. I think they should be opposed. I do not think they should be enacted.
I think the medical rights of people with disabilities and immunologic disorders, and those who want to mask to prevent getting sick at a time at which infectious diseases are still circulating and killing people, ought to take priority. Public health, in this case, should drive our policies about masks.

ILD Subtypes in Rheumatoid Arthritis Carry Different Risk Factor Profiles
TOPLINE:
Older age, male sex, and seropositivity are linked to a higher risk for rheumatoid arthritis–interstitial lung disease (RA-ILD) with a usual interstitial pneumonia (UIP) pattern, while only seropositivity is associated with RA-ILD with a nonspecific interstitial pneumonia pattern (NSIP).
METHODOLOGY:
- Researchers conducted a case-control study using data from two cohorts in the Mass General Brigham Healthcare system to examine the risk factors associated with different subtypes of RA-ILD.
- They identified 208 patients with RA-ILD (mean age at RA diagnosis, 50.7 years; 67.3% women) and 547 control participants with RA but no ILD (mean age at RA diagnosis, 49.1 years; 78.1% women), who had high-resolution computed tomography (HRCT) imaging data available.
- RA-ILD subtypes such as RA-UIP, RA-NSIP, organizing pneumonia, and others were determined with HRCT scans.
- The associations between demographics, lifestyle, and serologic factors and RA-ILD subtypes were evaluated using multivariable logistic regression analysis.
TAKEAWAY:
- The RA-UIP subtype, the one with worst prognosis, was associated with older age during the time of RA diagnosis (odds ratio [OR], 1.03 per year; 95% CI, 1.01-1.05), male sex (OR, 2.15; 95% CI, 1.33-3.48), and seropositivity (OR, 2.08; 95% CI, 1.24-3.48).
- On the other hand, the RA-NSIP subtype was significantly associated only with seropositivity (OR, 3.21; 95% CI, 1.36-7.56).
- Nonfibrotic ILDs were significantly associated with positive smoking status (OR, 2.81; 95% CI, 1.52-5.21) and seropositivity (OR, 2.09; 95% CI, 1.19-3.67).
- The combination of male sex, seropositivity, and positive smoking status was associated with a nearly sevenfold increased risk for RA-UIP (OR, 6.89; 95% CI, 2.41-19.69), compared with having no RA-ILD risk factors.
IN PRACTICE:
“These findings suggest that RA-ILD subtypes may have distinct risk factor profiles and emphasize the importance of further efforts to understand RA-ILD disease heterogeneity to inform screening and prognostication strategies,” the authors wrote.
SOURCE:
The study was led by Gregory C. McDermott, MD, MPH, Brigham and Women’s Hospital, Boston, and was published online on September 11, 2024, in Arthritis Care & Research.
LIMITATIONS:
This study relied on HRCT imaging, which may have introduced selection bias within the control groups. RA disease activity measures were not available for the Mass General Brigham Biobank RA cohort, which limited the analysis of the influence of disease activity on the risk for RA-ILD. Both cohorts predominantly involved White patients, which may have limited the generalizability of the findings to more diverse populations.
DISCLOSURES:
Some authors were supported by the Rheumatology Research Foundation Scientist Development Award, a VERITY Pilot & Feasibility Research Award, the Société Française de Rhumatologie, the National Institute of Arthritis and Musculoskeletal and Skin Diseases, and other sources. The authors declared receiving grant support, consulting fees, and honoraria from various organizations and pharmaceutical companies.

Minimal Risks With SBRT in Stage I NSCLC
TOPLINE:
METHODOLOGY:
- SBRT is generally considered a safe treatment option in patients with stage I NSCLC who have medically inoperable tumors or who refuse surgery. Although rare, clinically relevant acute toxicities or early mortality can occur.
- In the current real-world analysis, researchers explored toxicity and 90-day mortality outcomes in patients who received SBRT to develop a better understanding of how often they happen and whether certain patients are at higher risk.
- Researchers analyzed data from the Dutch Lung Cancer Audit for Radiotherapy database, which included 7279 patients with stage I NSCLC who received SBRT between January 2017 and December 2021.
- Participants had a mean age of 72.5 years; 21.6% were older than 80 years. Over half were men (50.7%), most (73.3%) had WHO scores of 0-1, and about two thirds (64.6%) had cT1a-b tumors, mostly in the upper lobes (65.2%).
- Prediction models for acute toxicity and 90-day mortality were developed and internally validated using logistic regression analysis. Acute toxicity was defined as grade 2 or higher radiation pneumonitis or grade 3 or higher non-hematologic toxicity within 90 days after SBRT. The 90-day mortality was defined as mortality from any cause within 90 days after SBRT.
TAKEAWAY:
- Acute toxicity was observed in 3.8% patients, with more common types including dyspnea (1.8%), radiation pneumonitis (1.2%), fatigue (0.3%), and dysphagia (0.2%).
- Predictors for acute toxicity included WHO performance status of 2 or higher (adjusted odds ratio [aOR], 1.89; P = .003), middle or lower lobe tumor location (aOR, 1.38), cT1c-cT2a stage (aOR, 1.66), as well as lower forced expiratory volume in 1 second and higher mean lung dose.
- Overall, 90-day mortality was observed in 1.7% patients, with predictors including male sex, WHO performance status of 2 or higher (aOR, 6.11; P < .001), and acute toxicity (aOR, 8.89; P < .001).
- Advanced age was not associated with a higher risk for acute toxicity or 90-day mortality.
IN PRACTICE:
“This real-world study confirms that clinically relevant acute toxicity after lung SBRT for stage I NSCLC is rare,” and the 90-day mortality rate is low, the authors wrote. “Although these findings could inform clinical practice and enable individualized risk estimations, these parameters (and the others in the presented nomograms) should not serve as contraindication for SBRT as the benefits in terms of local control and survival outweigh the risks in most patients.”
SOURCE:
This study, led by Peter S.N. van Rossum, MD, PhD, Amsterdam UMC in Amsterdam, the Netherlands, was published online in Journal of Thoracic Oncology.
LIMITATIONS:
Patients with ultracentral tumor locations were excluded, which may have limited the generalizability of the findings. The Dutch Lung Cancer Audit for Radiotherapy database does not register whether a patient has interstitial lung disease or whether the treated tumor is at a central location, which carry increased risks for toxicity. The findings may not be applicable to patients receiving combined immunotherapy and SBRT, as this combination was not included in the current analysis. External validation of the prediction models is needed for application outside the Netherlands.
DISCLOSURES:
The authors declared no conflicts of interest.

“This real-world study confirms that clinically relevant acute toxicity after lung SBRT for stage I NSCLC is rare,” and the 90-day mortality rate is low, the authors wrote. “Although these findings could inform clinical practice and enable individualized risk estimations, these parameters (and the others in the presented nomograms) should not serve as contraindication for SBRT as the benefits in terms of local control and survival outweigh the risks in most patients.”

LIMITATIONS:
Patients with ultracentral tumor locations were excluded, which may have limited the generalizability of the findings. The Dutch Lung Cancer Audit for Radiotherapy database does not register whether a patient has interstitial lung disease or whether the treated tumor is at a central location, which carry increased risks for toxicity. The findings may not be applicable to patients receiving combined immunotherapy and SBRT, as this combination was not included in the current analysis.

TOPLINE:
METHODOLOGY:
- SBRT is generally considered a safe treatment option in patients with stage I NSCLC who have medically inoperable tumors or who refuse surgery. Although rare, clinically relevant acute toxicities or early mortality can occur.
- In the current real-world analysis, researchers explored toxicity and 90-day mortality outcomes in patients who received SBRT to develop a better understanding of how often they happen and whether certain patients are at higher risk.
- Researchers analyzed data from the Dutch Lung Cancer Audit for Radiotherapy database, which included 7279 patients with stage I NSCLC who received SBRT between January 2017 and December 2021.
- Participants had a mean age of 72.5 years; 21.6% were older than 80 years. Over half were men (50.7%), most (73.3%) had WHO scores of 0-1, and about two thirds (64.6%) had cT1a-b tumors, mostly in the upper lobes (65.2%).
- Prediction models for acute toxicity and 90-day mortality were developed and internally validated using logistic regression analysis. Acute toxicity was defined as grade 2 or higher radiation pneumonitis or grade 3 or higher non-hematologic toxicity within 90 days after SBRT. The 90-day mortality was defined as mortality from any cause within 90 days after SBRT.
TAKEAWAY:
- Acute toxicity was observed in 3.8% patients, with more common types including dyspnea (1.8%), radiation pneumonitis (1.2%), fatigue (0.3%), and dysphagia (0.2%).
- Predictors for acute toxicity included WHO performance status of 2 or higher (adjusted odds ratio [aOR], 1.89; P = .003), middle or lower lobe tumor location (aOR, 1.38), cT1c-cT2a stage (aOR, 1.66), as well as lower forced expiratory volume in 1 second and higher mean lung dose.
- Overall, 90-day mortality was observed in 1.7% patients, with predictors including male sex, WHO performance status of 2 or higher (aOR, 6.11; P < .001), and acute toxicity (aOR, 8.89; P < .001).
- Advanced age was not associated with a higher risk for acute toxicity or 90-day mortality.

FDA Okays Osimertinib After CRT in Locally Advanced, Unresectable NSCLC
Specifically, the third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) was approved for patients whose disease has not progressed during or after concurrent or sequential platinum-based chemoradiation therapy and whose tumors have EGFR exon 19 deletions or exon 21 L858R mutations. Such EGFR mutations can be detected by an FDA-approved test.
The FDA approved osimertinib in combination with platinum-based chemotherapy as first-line treatment for patients with locally advanced or metastatic NSCLC with the same mutations in February. The EGFR-TKI also carries other indications, including as first-line monotherapy for locally advanced or metastatic EGFR-mutated NSCLC.
Trial Findings Supporting Latest Approval
AstraZeneca announced in June that osimertinib had been granted Priority Review and Breakthrough Therapy Designation for its newest indication.
The September 25 approval was based on findings from the randomized, placebo-controlled LAURA trial of 216 patients, which demonstrated improved median progression-free survival with osimertinib vs placebo (39.1 vs 5.6 months; hazard ratio, 0.16). Overall survival results were immature at the most recent analysis, but “no trend towards a detriment was observed,” with 36% of prespecified deaths for the final analysis reported, according to an FDA press release.
Adverse Events
Study participants were randomized 2:1 to receive the osimertinib recommended dose of 80 mg given orally once daily or placebo until disease progression or unacceptable toxicity. The most common adverse reactions, occurring in at least 20% of patients, were lymphopenia, leukopenia, interstitial lung disease/pneumonitis, thrombocytopenia, neutropenia, rash, diarrhea, nail toxicity, musculoskeletal pain, cough, and COVID-19 infection.

Pertussis Rates Up Compared With Recent Years
, according to data from the Centers for Disease Control and Prevention (CDC). Reports from several states illustrate this trend, thought to be due to reduced immunity across the country.
The Alaska Department of Health issued a statement on its website about the significant increase in pertussis cases in the state during the summer, with 90 cases in July and 61 in August, compared with 24 in June and a total of 26 cases in 2023.
Similarly, the Florida Department of Health reported a pertussis increase in July 2024 that was higher than the June 2024 case count and also above the previous 5-year average.
Experts in these and other states suggest that several factors are driving the nationwide increase, including the fact that fewer people are consistently wearing masks. The mass masking during the COVID-19 pandemic caused a significant drop in pertussis, but the latest data suggest a return to prepandemic levels, and waning immunity likely plays a role as well.
Pertussis, also known as whooping cough, typically begins with symptoms similar to those of the common cold, including runny nose, sneezing, mild fever, and cough, according to the CDC. However, babies with whooping cough may experience trouble breathing rather than a cough. The coughing fits often associated with pertussis may not start until 2 weeks after the onset of other symptoms, according to the CDC.
Those who have been vaccinated against pertussis can still become infected, but the risk is lower, and the illness, if it occurs, is likely to be milder. Complications such as apnea, pneumonia, and convulsions can occur in babies younger than 1 year, especially if they have not been vaccinated, according to the CDC.
Beyond Easing Pandemic Precautions
Many respiratory-based infections dipped during the COVID-19 pandemic, almost certainly from the multifactorial interventions of masking, distancing, and the general lack of comingling, said David J. Cennimo, MD, associate professor of medicine & pediatrics in the Division of Infectious Diseases at Rutgers New Jersey Medical School, Newark, New Jersey, in an interview.
The number of cases of many of these diseases returned to previous levels after COVID-19 restrictions were lifted, he said.
“However, we know pertussis immunity wanes over time. Children get DTaP at 2, 4, 6, and 15 months, and a Tdap booster at 11-12 years old gets them to adulthood,” Dr. Cennimo said. Adults should be getting a Tdap every 10 years, he added.
The latest available CDC data indicate that Tdap vaccine coverage in adults is approximately 40%, which means that there may be a large number of susceptible people who can become infected and propagate to others, said Dr. Cennimo.
Not Just the Young Ones
A recent pertussis outbreak among college students in Virginia highlighted the fact that the infection can affect all ages, and that the effectiveness of childhood vaccines may decrease over time. The majority of the recently diagnosed cases occurred in individuals who had been previously vaccinated, according to a press release from the Virginia Department of Health.
Clinical Clues
The initial stage of pertussis infection looks like a common cold with symptoms of upper respiratory infection, Dr. Cennimo told this news organization. “Unless there is reason to suspect pertussis exposure, it would almost certainly be missed,” he noted.
The characteristic barking/seal-like cough is mostly seen in children, said Dr. Cennimo. Adults and children can experience coughing fits that can lead to shortness of breath and/or vomiting, which would raise suspicion for pertussis, but is not universally present, he said. The convalescent stage of pertussis can be prolonged and is characterized by chronic coughing. “In the past, pertussis had been called the 100-day cough,” and at that point, treatment is ineffective, Dr. Cennimo said.
In clinical practice, “I advise everyone to get the Tdap vaccine every 10 years,” and remember that the “Td” is the every 10-year tetanus shot as well, Dr. Cennimo told this news organization. Reassure patients that the Tdap can be given with other vaccines, he said, and remind patients that, as with any of the respiratory illnesses, they should stay home if sick, cover a cough, consider wearing a mask in public, and wash hands frequently, he said.
Dr. Cennimo had no financial conflicts to disclose.

A Rare Case of a Splenic Abscess as the Origin of Illness in Exudative Pleural Effusion
Splenic abscesses are a rare occurrence that represent a marginal proportion of intra-abdominal infections. One study found splenic abscesses in only 0.14% to 0.70% of autopsies and none of the 540 abdominal abscesses they examined originated in the spleen.1 Patients with splenic abscesses tend to present with nonspecific symptoms such as fevers, chills, and abdominal pain.2 Imaging modalities such as abdominal ultrasound and computed tomography (CT) are vital to the workup and diagnosis identification.2 Splenic abscesses are generally associated with another underlying process, as seen in patients who are affected by endocarditis, trauma, metastatic infection, splenic infarction, or neoplasia.2
Pleural effusions, or the buildup of fluid within the pleural space, is a common condition typically secondary to another disease.3 Clinical identification of the primary condition may be challenging.3 In the absence of a clear etiology, such as obvious signs of congestive heart failure, further differentiation relies upon pleural fluid analysis, beginning with the distinction between exudate (inflammatory) and transudate (noninflammatory). 3,4 This distinction can be made using Light’s criteria, which relies on protein and lactate dehydrogenase (LDH) ratios between the pleural fluid and serum (Table 1).5 Though rare, half of splenic abscesses are associated with pleural effusion.6 As an inflammatory condition, splenic abscesses have been classically described as a cause of exudative pleural effusions.5,6
A myelodysplastic syndrome is a group of diseases that arise from malignant hematopoietic stem cells, leading to the proliferation of the malignant cells and faulty production of other bone marrow products.7 These disorders can range from single to multilineage dysplasia. Cells are often left in an immature blast form, unable to function appropriately, and vulnerable to destruction. Patients with myeloproliferative disorders frequently suffer from leukopenia and infections attributable to known quantitative and qualitative defects of neutrophils.8
CASE PRESENTATION
A male aged 80 years presented to the Central Texas Veterans Affairs Hospital (CTVAH) with shortness of breath, weight loss, and fever. On admission, his medical history was notable for atrial fibrillation, myelodysplastic syndrome, hypertension, hyperlipidemia, stable ascending aortic aneurysm, and Vitamin B12 deficiency. A chest CT showed a large left pleural effusion (Figure 1). Additionally, the radiology report noted a nonspecific 4- to 5-cm lobulated subdiaphragmatic mass within the anterior dome of the spleen with surrounding soft tissue swelling and splenomegaly (Figure 2).
Initial thoracentesis was performed with 1500 mL of straw-colored fluid negative for bacteria, fungi, malignancy, and acid-fast organisms (Tables 2 and 3). The pleural effusion persisted, requiring a second thoracentesis 2 days later that was positive for Escherichia coli (E coli). Given the exudative nature and positive culture, a chest tube was placed, and the pleural effusion was therefore felt to be an empyema, arousing suspicion that the splenic mass seen on CT was an abscess. The site was accessed by interventional radiology, purulent fluid aspirated, and a drain was placed. Cultures grew E coli sensitive to ceftriaxone. Despite receiving intravenous ceftriaxone 2 g daily, the pleural effusion became further complicated due to chest tube obstruction and persistent drainage.
The patient was discharged to Baylor Scott & White Medical Center in Temple, Texas where he underwent decortication with cardiothoracic surgery with several pleural adhesions noted. Following surgery the patient was readmitted to CTVAH and continued ceftriaxone therapy following the infectious disease specialist's recommendation. He was discharged with plans to return to CTVAH for continued care. The patient was readmitted and transitioned to oral levofloxacin 500 mg daily and received physical and occupational therapy. He showed dramatic improvement on this regimen, with a 3-week follow-up CT that indicated only a small left pleural effusion and a 28 mm × 11 mm × 10 mm lesion in the anterior superior spleen. The patient had not returned for further evaluation by thoracic surgery; however, he has continued to see CTVAH primary care without reported recurrence of symptoms.
DISCUSSION
Splenic abscesses are a rare condition typically characterized by hematogenous spread of bacteria from another source, most commonly the endocardium.2 Other differential diagnoses include bacteremia or spread from an intra-abdominal site.2 Staphylococcus aureus and E coli are the most common bacteria seen in splenic abscesses. 2 Treatment includes antibiotics, percutaneous drainage, and, as a last resort, splenectomy.2
Our patient was found to have grown E coli, but no source indicative of spread was identified. He had negative blood cultures, negative findings for intra-abdominal pathologies on CT scans, and a negative echocardiogram for endocarditis. A bronchoscopy showed no evidence of a source from the lungs, and specimens taken from the pleural adhesions were negative for malignancy and bacteria.
This patient had risk factors for the illness, namely his history of being immunocompromised secondary to myelodysplastic syndrome.7 Accordingly, the patient showed persistent leukopenia with neutropenia and lymphocytopenia, which would not be expected for most patients with such an extensive infection. 8 While being immunocompromised undoubtedly contributed to the severity of the patient’s presentation and slow recovery, it does not explain the etiology or origin of his infection. This patient differs from current literature in that his splenic abscess was truly idiopathic rather than resulting from an alternative source.
Complications of splenic abscesses include pleural effusions, as seen with this patient, as well as pneumonia, pneumothorax, hemorrhage, subphrenic abscess, and intraabdominal perforation, among others.2 We determined conclusively that the patient’s pleural effusion was secondary to the splenic abscess, and excluded other bacterial foci strongly suggests that the spleen was the origin of the illness.
CONCLUSIONS
This case suggests splenic abscesses should be considered when evaluating pleural effusion. It further demonstrates that the spleen may be the central source of infection in the absence of iatrogenic inoculation or bacteremia. We hope our findings may lead to earlier identification in similar scenarios and improved patient outcomes in a multidisciplinary approach.

He was discharged with plans to return to CTVAH for continued care. The patient was readmitted and transitioned to oral levofloxacin 500 mg daily and received physical and occupational therapy. He showed dramatic improvement on this regimen, with a 3-week follow-up CT that indicated only a small left pleural effusion and a 28 mm × 11 mm × 10 mm lesion in the anterior superior spleen. The patient had not returned for further evaluation by thoracic surgery; however, he has continued to see CTVAH primary care without reported recurrence of symptoms.
DISCUSSION
Splenic abscesses are a rare condition typically characterized by hematogenous spread of bacteria from another source, most commonly the endocardium.2 Other differential diagnoses include bacteremia or spread from an intra-abdominal site.2 Staphylococcus aureus and E coli are the most common bacteria seen in splenic abscesses. 2 Treatment includes antibiotics, percutaneous drainage, and, as a last resort, splenectomy.2
Our patient was found to have grown E coli, but no source indicative of spread was identified. He had negative blood cultures, negative findings for intra-abdominal pathologies on CT scans, and a negative echocardiogram for endocarditis. A bronchoscopy showed no evidence of a source from the lungs, and specimens taken from the pleural adhesions were negative for malignancy and bacteria.
This patient had risk factors for the illness, namely his history of being immunocompromised secondary to myelodysplastic syndrome.7 Accordingly, the patient showed persistent leukopenia with neutropenia and lymphocytopenia, which would not be expected for most patients with such an extensive infection. 8 While being immunocompromised undoubtedly contributed to the severity of the patient’s presentation and slow recovery, it does not explain the etiology or origin of his infection. This patient differs from current literature in that his splenic abscess was truly idiopathic rather than resulting from an alternative source.
Complications of splenic abscesses include pleural effusions, as seen with this patient, as well as pneumonia, pneumothorax, hemorrhage, subphrenic abscess, and intraabdominal perforation, among others.2 We determined conclusively that the patient’s pleural effusion was secondary to the splenic abscess, and excluded other bacterial foci strongly suggests that the spleen was the origin of the illness.
CONCLUSIONS
This case suggests splenic abscesses should be considered when evaluating pleural effusion. It further demonstrates that the spleen may be the central source of infection in the absence of iatrogenic inoculation or bacteremia. We hope our findings may lead to earlier identification in similar scenarios and improved patient outcomes in a multidisciplinary approach.
Splenic abscesses are a rare occurrence that represent a marginal proportion of intra-abdominal infections. One study found splenic abscesses in only 0.14% to 0.70% of autopsies and none of the 540 abdominal abscesses they examined originated in the spleen.1 Patients with splenic abscesses tend to present with nonspecific symptoms such as fevers, chills, and abdominal pain.2 Imaging modalities such as abdominal ultrasound and computed tomography (CT) are vital to the workup and diagnosis identification.2 Splenic abscesses are generally associated with another underlying process, as seen in patients who are affected by endocarditis, trauma, metastatic infection, splenic infarction, or neoplasia.2
Pleural effusions, or the buildup of fluid within the pleural space, is a common condition typically secondary to another disease.3 Clinical identification of the primary condition may be challenging.3 In the absence of a clear etiology, such as obvious signs of congestive heart failure, further differentiation relies upon pleural fluid analysis, beginning with the distinction between exudate (inflammatory) and transudate (noninflammatory). 3,4 This distinction can be made using Light’s criteria, which relies on protein and lactate dehydrogenase (LDH) ratios between the pleural fluid and serum (Table 1).5 Though rare, half of splenic abscesses are associated with pleural effusion.6 As an inflammatory condition, splenic abscesses have been classically described as a cause of exudative pleural effusions.5,6
A myelodysplastic syndrome is a group of diseases that arise from malignant hematopoietic stem cells, leading to the proliferation of the malignant cells and faulty production of other bone marrow products.7 These disorders can range from single to multilineage dysplasia. Cells are often left in an immature blast form, unable to function appropriately, and vulnerable to destruction. Patients with myeloproliferative disorders frequently suffer from leukopenia and infections attributable to known quantitative and qualitative defects of neutrophils.8
CASE PRESENTATION
A male aged 80 years presented to the Central Texas Veterans Affairs Hospital (CTVAH) with shortness of breath, weight loss, and fever. On admission, his medical history was notable for atrial fibrillation, myelodysplastic syndrome, hypertension, hyperlipidemia, stable ascending aortic aneurysm, and Vitamin B12 deficiency. A chest CT showed a large left pleural effusion (Figure 1). Additionally, the radiology report noted a nonspecific 4- to 5-cm lobulated subdiaphragmatic mass within the anterior dome of the spleen with surrounding soft tissue swelling and splenomegaly (Figure 2).
Initial thoracentesis was performed with 1500 mL of straw-colored fluid negative for bacteria, fungi, malignancy, and acid-fast organisms (Tables 2 and 3). The pleural effusion persisted, requiring a second thoracentesis 2 days later that was positive for Escherichia coli (E coli). Given the exudative nature and positive culture, a chest tube was placed, and the pleural effusion was therefore felt to be an empyema, arousing suspicion that the splenic mass seen on CT was an abscess. The site was accessed by interventional radiology, purulent fluid aspirated, and a drain was placed. Cultures grew E coli sensitive to ceftriaxone. Despite receiving intravenous ceftriaxone 2 g daily, the pleural effusion became further complicated due to chest tube obstruction and persistent drainage.
The patient was discharged to Baylor Scott & White Medical Center in Temple, Texas where he underwent decortication with cardiothoracic surgery with several pleural adhesions noted. Following surgery the patient was readmitted to CTVAH and continued ceftriaxone therapy following the infectious disease specialist's recommendation. He was discharged with plans to return to CTVAH for continued care. The patient was readmitted and transitioned to oral levofloxacin 500 mg daily and received physical and occupational therapy.

FDA Expands Indication for Amivantamab in Lung Cancer
Amivantamab with carboplatin and pemetrexed is now indicated for adults with locally advanced or metastatic NSCLC with EGFR exon 19 deletions or exon 21 L858R substitution mutations whose disease has progressed on or after treatment with an EGFR tyrosine kinase inhibitor (TKI).
The FDA has already approved first-line use of amivantamab in combination with carboplatin and pemetrexed in patients with locally advanced or metastatic NSCLC with EGFR exon 20 insertion mutations, as reported by Medscape Medical News.
The second-line approval for amivantamab plus chemotherapy “may address the most common mechanisms of treatment resistance to third-generation EGFR TKIs, such as osimertinib, in the first line,” Martin Dietrich, MD, PhD, oncologist, Cancer Care Centers of Brevard in Florida, said in a company news release.
“This multitargeted combination extended progression-free survival (PFS) and improved overall response compared to chemotherapy alone, offering an important and effective new second-line option for patients,” Dr. Dietrich added.
The second-line indication is supported by the phase 3 MARIPOSA-2 study, which included 657 patients with locally advanced or metastatic NSCLC with EGFR exon 19 deletions or exon 21 L858R substitution mutations and disease progression on or after receiving osimertinib.
The study demonstrated a 52% reduced risk of disease progression or death when amivantamab was added to carboplatin and pemetrexed (hazard ratio, 0.48).
Median PFS was 6.3 months with amivantamab vs 4.2 months with chemotherapy alone. The confirmed objective response rate was 53% in the amivantamab plus chemotherapy group vs 29% in the chemotherapy only group.
The most common adverse reactions, occurring in at least 20% of patients, were rash, infusion-related reactions, fatigue, nail toxicity, nausea, constipation, edema, stomatitis, decreased appetite, musculoskeletal pain, vomiting, and COVID-19 infection.
The company noted that amivantamab in combination with chemotherapy is the only category 1 treatment option in National Comprehensive Cancer Network clinical practice guidelines for patients with EGFR-mutated NSCLC who have progressed on osimertinib and who are symptomatic with multiple lesions.

Cancer Risk: Are Pesticides the New Smoking?
Pesticides have transformed modern agriculture by boosting production yields and helping alleviate food insecurity amid rapid global population growth. However, from a public health perspective, exposure to pesticides has been linked to numerous harmful effects, including neurologic disorders like Parkinson’s disease, weakened immune function, and an increased risk for cancer.
thus offering a limited perspective.
A comprehensive assessment of how pesticide use affects cancer risk across a broader population has yet to be conducted.
A recent population-level study aimed to address this gap by evaluating cancer risks in the US population using a model that accounts for pesticide use and adjusts for various factors. The goal was to identify regional disparities in exposure and contribute to the development of public health policies that protect populations from potential harm.
Calculating Cancer Risk
Researchers developed a model using several data sources to estimate the additional cancer risk from agricultural pesticide use. Key data included:
- Pesticide use data from the US Geological Survey in 2019, which covered 69 agricultural pesticides across 3143 counties
- Cancer incidence rates per 100,000 people, which were collected between 2015 and 2019 by the National Institutes of Health and the Centers for Disease Control and Prevention; these data covered various cancers, including bladder, colorectal, leukemia, lung, non-Hodgkin lymphoma, and pancreatic cancers
- Covariates, including smoking prevalence, the Social Vulnerability Index, agricultural land use, and total US population in 2019
Pesticide use profile patterns were developed using latent class analysis, a statistical method used to identify homogeneous subgroups within a heterogeneous population. A generalized linear model then estimated how these pesticide use patterns and the covariates affected cancer incidence.
The model highlighted regions with the highest and lowest “additional” cancer risks linked to pesticide exposure, calculating the estimated increase in cancer cases per year that resulted from variations in agricultural pesticide use.
Midwest Most Affected
While this model doesn’t establish causality or assess individual risk, it reveals regional trends in the association between pesticide use patterns and cancer incidence from a population-based perspective.
The Midwest, known for its high corn production, emerged as the region most affected by pesticide use. Compared with regions with the lowest risk, the Midwest faced an additional 154,541 cancer cases annually across all types. For colorectal and pancreatic cancers, the yearly increases were 20,927 and 3835 cases, respectively. Similar trends were observed for leukemia and non-Hodgkin lymphoma.
Pesticides vs Smoking
The researchers also estimated the additional cancer risk related to smoking, using the same model. They found that pesticides contributed to a higher risk for cancer than smoking in several cases.
The most significant difference was observed with non-Hodgkin lymphoma, where pesticides were linked to 154.1% more cases than smoking. For all cancers combined, as well as bladder cancer and leukemia, the increases were moderate: 18.7%, 19.3%, and 21.0%, respectively.
This result highlights the importance of considering pesticide exposure alongside smoking when studying cancer risks.
Expanding Scope of Research
Some limitations of this study should be noted. Certain counties lacked complete data, and there was heterogeneity in the size and population of the counties studied. The research also did not account for seasonal and migrant workers, who are likely to be heavily exposed. In addition, the data used in the study were not independently validated, and they could not be used to assess individual risk.
The effect of pesticides on human health is a vast and critical field of research, often focusing on a limited range of pesticides or specific cancers. This study stands out by taking a broader, more holistic approach, aiming to highlight regional inequalities and identify less-studied pesticides that could be future research priorities.
Given the significant public health impact, the authors encouraged the authorities to share these findings with the most vulnerable communities to raise awareness.

Benralizumab Now FDA Approved to Treat EGPA Vasculitis
The Food and Drug Administration (FDA) has approved benralizumab (Fasenra) for the treatment of adults with eosinophilic granulomatosis with polyangiitis (EGPA), formerly known as Churg-Strauss syndrome.
The drug is the second approved biologic for the treatment of EGPA. The first, mepolizumab (Nucala), was approved in 2017.
“This disease has a devastating impact on patients and the quality of their life, and they need more treatment options. The approval of another treatment in EGPA is welcome news to the approximately 15,000 patients living in the US with this difficult-to-treat rare disease,” said Joyce Kullman, executive director of the Vasculitis Foundation, in a press release on September 18.
Benralizumab, developed by AstraZeneca, is a monoclonal antibody against the interleukin-5 alpha receptor expressed on eosinophils. The drug was first approved in 2017 as an add-on treatment for patients 12 years and older with severe eosinophilic asthma, and is now approved for use in children aged 6 years and older.
The new indication was based on positive results from a noninferiority trial comparing benralizumab and mepolizumab. For the trial, published in the New England Journal of Medicine earlier in 2024, 140 adults with relapsing or refractory EGPA were randomized to a 30-mg subcutaneous injection of benralizumab or three separate 100-mg mepolizumab injections every 4 weeks for 1 year. At weeks 36 and 48, 59% of patients in the benralizumab group and 56% of patients in the mepolizumab group achieved remission (95% CI, –13 to 18; P = .73 for superiority). From week 42 to 52, 41% of patients who received benralizumab completely stopped taking oral glucocorticoids, compared with 26% of those who received mepolizumab.
“Patients often rely on long-term oral corticosteroids, which can cause serious and lasting side effects. Benralizumab is a much-needed treatment option, with data showing that not only is remission an achievable goal for EGPA patients, but benralizumab can also help patients taper off steroid therapy,” Michael Wechsler, MD, director of The Asthma Institute at National Jewish Health in Denver, Colorado, and the international coordinating investigator for the clinical trial, said in the press release.
Benralizumab is administered via subcutaneous injection. In adults with EGPA, the recommended dosage is 30 mg every 4 weeks for the first three doses, then once every 8 weeks.
The most common adverse reactions include headache and pharyngitis, according to the prescribing information.
Benralizumab is also in development for the treatment of chronic obstructive pulmonary disease, chronic rhinosinusitis with nasal polyps, and hypereosinophilic syndrome.

Benralizumab, developed by AstraZeneca, is a monoclonal antibody against the interleukin-5 alpha receptor expressed on eosinophils. The drug was first approved in 2017 as an add-on treatment for patients 12 years and older with severe eosinophilic asthma, and is now approved for use in children aged 6 years and older.
The new indication was based on positive results from a noninferiority trial comparing benralizumab and mepolizumab. For the trial, published in the New England Journal of Medicine earlier in 2024, 140 adults with relapsing or refractory EGPA were randomized to a 30-mg subcutaneous injection of benralizumab or three separate 100-mg mepolizumab injections every 4 weeks for 1 year. At weeks 36 and 48, 59% of patients in the benralizumab group and 56% of patients in the mepolizumab group achieved remission (95% CI, –13 to 18; P = .73 for superiority). From week 42 to 52, 41% of patients who received benralizumab completely stopped taking oral glucocorticoids, compared with 26% of those who received mepolizumab.
“Patients often rely on long-term oral corticosteroids, which can cause serious and lasting side effects. Benralizumab is a much-needed treatment option, with data showing that not only is remission an achievable goal for EGPA patients, but benralizumab can also help patients taper off steroid therapy,” Michael Wechsler, MD, director of The Asthma Institute at National Jewish Health in Denver, Colorado, and the international coordinating investigator for the clinical trial, said in the press release.
Benralizumab is administered via subcutaneous injection. In adults with EGPA, the recommended dosage is 30 mg every 4 weeks for the first three doses, then once every 8 weeks.
The most common adverse reactions include headache and pharyngitis, according to the prescribing information.
Benralizumab is also in development for the treatment of chronic obstructive pulmonary disease, chronic rhinosinusitis with nasal polyps, and hypereosinophilic syndrome.

The Food and Drug Administration (FDA) has approved benralizumab (Fasenra) for the treatment of adults with eosinophilic granulomatosis with polyangiitis (EGPA), formerly known as Churg-Strauss syndrome.
The drug is the second approved biologic for the treatment of EGPA. The first, mepolizumab (Nucala), was approved in 2017.
