PsA: Women experience greater disease burden than men
Key clinical point: Among patients with psoriatic arthritis (PsA) women experienced significantly higher disease burden than men despite similar disease activity and comparable treatments.
Major finding: Despite similar disease duration (P = .42), disease presentation, and biologic use (P = .38), women vs men had worse mean quality-of-life (0.80 vs 0.82; P = .02) and disability and physical functioning (0.56 vs 0.41; P < .01) scores, greater degree of work activity impairment (27.9% vs 24.6%; P < .01), and higher pain and fatigue scores (P < .01).
Study details: This study analyzed the data of 2270 patients with PsA (1223 men and 1047 women) from the Adelphi PsA Disease Specific Programme.
Disclosures: This study was funded by Janssen Research & Development, LLC. Three authors declared being employees of Janssen and owning stocks in Janssen/Johnson and Johnson. Some authors declared receiving research grants and consulting fees from several sources, including Janssen.

How useful is CRP as a marker for assessing disease activity in PsA?
Key clinical point: Levels of C-reactive protein (CRP), a classic inflammatory marker, do not adequately reflect the level of disease activity (DA) in patients with psoriatic arthritis (PsA).
Major finding: CRP status was only associated with the erythrocyte sedimentation rate (odds ratio 1.04; P = .005) and not with any DA-related parameter. Among patients with normal CRP levels, a substantial proportion (45.9%) of patients were in non-minimal DA state, with 21.2% having moderate DA and 5.9% having high DA.
Study details: Findings are from a cross-sectional study including 128 patients with PsA, of which 66.4% had normal CRP levels (≤0.5 mg/dL) and the remaining had high CRP levels (>0.5 mg/dL).
Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.

Rapid and sustained improvement in PsA with ustekinumab
Key clinical point: Patients with active psoriatic arthritis (PsA) who received ustekinumab for 160 weeks showed rapid and sustained improvements in the signs and symptoms of PsA.
Major finding: A decrease in both tender joint count (TJC; 8.0 to 5.8) and swollen joint count (SJC; 4.5 to 3.1) was observed from baseline to week 4, with further decrease until week 28. Improvements were sustained up to week 160 (TJC 1.0; SJC 0.4). Minimal disease activity was achieved by 31.9% of patients at week 28 and 33.6% of patients at week 52.
Study details: Findings are from the prospective, non-interventional SUSTAIN study including 129 patients with active PsA and a previous inadequate response to disease-modifying antirheumatic drugs who were followed up to week 160.
Disclosures: The SUSTAIN study was funded by Janssen-Cilag GmbH. Three authors declared being employees of Janssen-Cilag GmbH and holding stocks in Johnson and Johnson, the parent company of Janssen. The other authors declared no conflicts of interest.

Isolated axial PsA and eventual development of peripheral disease
Key clinical point: Patients with isolated axial psoriatic arthritis (PsA) had a better functional status than those with both axial and peripheral disease. Human leucocyte antigen (HLA)-B*27 positivity was associated with isolated axial PsA and predicted the development of peripheral disease over time.
Major finding: Compared with patients with concomitant axial and peripheral disease, HLA-B*27 positivity (odds ratio [OR] 25.00; P < .003) and lower Health Assessment Questionnaire scores (OR 0.004; P < .01) were associated with isolated axial disease. HLA-B*27 positivity predicted the development of peripheral PsA in patients with isolated axial PsA (hazard ratio 7.544; P < .006).
Study details: Findings are from a longitudinal study including 1688 patients with ankylosing spondylitis and psoriasis and 1576 patients with PsA, of which 32 had isolated axial disease and 463 had axial with peripheral disease.
Disclosures: The University of Toronto Psoriatic Arthritis Program is supported by a grant from the Krembil Foundation. The authors declared no conflicts of interest.

Secukinumab delays disease flare in juvenile PsA
Key clinical point: Secukinumab significantly delayed disease flare compared with placebo and showed a consistent safety profile in patients with juvenile psoriatic arthritis (JPsA).
Major finding: Secukinumab vs placebo was associated with a significant delay in disease flare (hazard ratio 0.15; P < .001) and a higher proportion of patients achieving juvenile idiopathic arthritis American College of Rheumatology 30 response at week 104 (86.7% vs 62.5%). No new safety concerns were observed.
Study details: Findings are from a treatment-withdrawal, phase 3 study including 86 biologic-naive patients with active enthesitis-related arthritis (n = 52) or JPsA (n = 34) who were randomly assigned to receive secukinumab or placebo for up to 104 weeks.

Game-changing results in fluid resuscitation for acute pancreatitis
Early, aggressive fluid resuscitation in acute pancreatitis led to a higher incidence of fluid overload without improving clinical outcomes in the landmark WATERFALL trial.
Early aggressive hydration is widely recommended for the management of acute pancreatitis, but evidence for this practice is limited.
“The WATERFALL trial demonstrates that aggressive fluid resuscitation in acute pancreatitis is not safe, it is not associated with improved outcomes, and it should be abandoned,” Enrique de-Madaria, MD, PhD, with Hospital General Universitario Dr. Balmis, Alicante, Spain, told this news organization.
The trial settles a “new and clear reference for fluid resuscitation in this frequent disease: lactated Ringer’s solution 1.5 mL/kg per hour (preceded by a 10 mL/kg bolus over 2 hours only in case of hypovolemia),” added Dr. de-Madaria, president of the Spanish Association of Gastroenterology.
“This moderate fluid resuscitation strategy is associated with a much lower frequency of fluid overload and a trend toward improved outcomes. For such reasons, it should be considered as a new standard of care in the early management of acute pancreatitis,” Dr. de-Madaria said.
The WATERFALL trial results were published in the New England Journal of Medicine.
The results are “stunning and, given the carefully crafted trial methods, irrefutable,” Timothy Gardner, MD, with the section of gastroenterology and hepatology, Dartmouth–Hitchcock Medical Center, Lebanon, N.H., wrote in a linked editorial.
Trial details
The trial was conducted at 18 centers across India, Italy, Mexico, and Spain. Patients who presented with acute pancreatitis were randomly allocated to aggressive or moderate resuscitation with lactated Ringer’s solution.
Aggressive fluid resuscitation consisted of a bolus of 20 mL/kg of body weight, followed by 3 mL/kg per hour. Moderate fluid resuscitation consisted of a bolus of 10 mL/kg in patients with hypovolemia or no bolus in patients with normovolemia, followed by 1.5 mL/kg per hour in all patients in this group.
Patients were assessed at 12, 24, 48, and 72 hours, and fluid resuscitation was adjusted according to clinical status.
A total of 249 patients were included in the interim analysis – 122 in the aggressive-resuscitation group and 127 in the moderate-resuscitation group.
The data and safety monitoring board terminated the trial at the first interim safety analysis as a result of the development of fluid overload in 20.5% of the patients in the aggressive-resuscitation group versus 6.3% of those in the moderate-resuscitation group (adjusted relative risk, 2.85; 95% confidence interval, 1.36-5.94; P = .004).
“An increased risk of fluid overload was detected in the overall population of patients and also in subgroups of patients without systemic inflammatory response syndrome at baseline, patients with SIRS at baseline (thus, with a higher risk of development of severe pancreatitis), and patients with hypovolemia,” the investigators reported.
This clear signal of harm was coupled with no significant difference in the incidence of moderately severe or severe pancreatitis (22.1% in the aggressive-resuscitation group and 17.3% in the moderate-resuscitation group; aRR, 1.30; 95% CI, 0.78-2.18; P = .32).
Patients in the aggressive-resuscitation group spent a median of 6 days in the hospital, compared with 5 days for patients in the moderate-resuscitation group.
“These findings do not support current management guidelines, which recommend early aggressive resuscitation for the treatment of acute pancreatitis,” the study team wrote.
‘Landmark’ trial
This is a “landmark” trial and “so clinically relevant because of its choice of real world-appropriate aggressive-resuscitation and moderate-resuscitation treatment groups, its use of pancreatitis severity as the main clinical outcome, and its reliance on the carefully defined variable of fluid overload as the main safety outcome,” Dr. Gardner wrote in his editorial.
“Unlike in most other randomized, controlled trials of fluid resuscitation in acute pancreatitis, patients with varying baseline pancreatitis severity were included, and changes in the rate of resuscitation were determined on the basis of a dynamic assessment of hemodynamic testing, imaging, and clinical factors,” he added.
Dr. Gardner said the WATERFALL trial results lead to several conclusions.
First, the need to focus on a steady rate of initial resuscitation – no more than 1.5 mL/kg of body weight per hour. Clinicians should administer a bolus of 10 mL/kg only if there are signs of initial hypovolemia.
Second, that careful clinical and hemodynamic monitoring are essential during the first 72 hours after admission to make sure that patients remain euvolemic and to avoid fluid overload.
Third, that diuresis in patients with fluid overload in the first 72 hours is most likely beneficial and certainly not detrimental to important clinical outcomes.
Dr. Gardner said the trial also highlights the need to focus research efforts on evaluating other pharmacologic therapies instead of crystalloid fluids.
“Performing randomized controlled trials in acute pancreatitis is notoriously difficult, and the limited human and financial resources that are available for appropriately powered trials in this field post WATERFALL are much better spent on comparative-effectiveness and placebo-controlled trials evaluating new therapeutic agents,” Dr. Gardner said.
“Now that we have gone over the WATERFALL, it is time to look downstream at new targets to treat this challenging disease,” he concluded.
Support for the trial was provided by Instituto de Salud Carlos III, the Spanish Association of Gastroenterology, and ISABIAL (Instituto de Investigación Sanitaria y Biomédica de Alicante).

First, the need to focus on a steady rate of initial resuscitation – no more than 1.5 mL/kg of body weight per hour. Clinicians should administer a bolus of 10 mL/kg only if there are signs of initial hypovolemia.
Second, that careful clinical and hemodynamic monitoring are essential during the first 72 hours after admission to make sure that patients remain euvolemic and to avoid fluid overload.
Third, that diuresis in patients with fluid overload in the first 72 hours is most likely beneficial and certainly not detrimental to important clinical outcomes.
Dr. Gardner said the trial also highlights the need to focus research efforts on evaluating other pharmacologic therapies instead of crystalloid fluids.
“Performing randomized controlled trials in acute pancreatitis is notoriously difficult, and the limited human and financial resources that are available for appropriately powered trials in this field post WATERFALL are much better spent on comparative-effectiveness and placebo-controlled trials evaluating new therapeutic agents,” Dr. Gardner said.
“Now that we have gone over the WATERFALL, it is time to look downstream at new targets to treat this challenging disease,” he concluded.
Support for the trial was provided by Instituto de Salud Carlos III, the Spanish Association of Gastroenterology, and ISABIAL (Instituto de Investigación Sanitaria y Biomédica de Alicante).

Early, aggressive fluid resuscitation in acute pancreatitis led to a higher incidence of fluid overload without improving clinical outcomes in the landmark WATERFALL trial.
Early aggressive hydration is widely recommended for the management of acute pancreatitis, but evidence for this practice is limited.
“The WATERFALL trial demonstrates that aggressive fluid resuscitation in acute pancreatitis is not safe, it is not associated with improved outcomes, and it should be abandoned,” Enrique de-Madaria, MD, PhD, with Hospital General Universitario Dr. Balmis, Alicante, Spain, told this news organization.
The trial settles a “new and clear reference for fluid resuscitation in this frequent disease: lactated Ringer’s solution 1.5 mL/kg per hour (preceded by a 10 mL/kg bolus over 2 hours only in case of hypovolemia),” added Dr. de-Madaria, president of the Spanish Association of Gastroenterology.
“This moderate fluid resuscitation strategy is associated with a much lower frequency of fluid overload and a trend toward improved outcomes. For such reasons, it should be considered as a new standard of care in the early management of acute pancreatitis,” Dr. de-Madaria said.
The WATERFALL trial results were published in the New England Journal of Medicine.
The results are “stunning and, given the carefully crafted trial methods, irrefutable,” Timothy Gardner, MD, with the section of gastroenterology and hepatology, Dartmouth–Hitchcock Medical Center, Lebanon, N.H., wrote in a linked editorial.
Trial details
The trial was conducted at 18 centers across India, Italy, Mexico, and Spain. Patients who presented with acute pancreatitis were randomly allocated to aggressive or moderate resuscitation with lactated Ringer’s solution.
Aggressive fluid resuscitation consisted of a bolus of 20 mL/kg of body weight, followed by 3 mL/kg per hour. Moderate fluid resuscitation consisted of a bolus of 10 mL/kg in patients with hypovolemia or no bolus in patients with normovolemia, followed by 1.5 mL/kg per hour in all patients in this group.
Patients were assessed at 12, 24, 48, and 72 hours, and fluid resuscitation was adjusted according to clinical status.
A total of 249 patients were included in the interim analysis – 122 in the aggressive-resuscitation group and 127 in the moderate-resuscitation group.
The data and safety monitoring board terminated the trial at the first interim safety analysis as a result of the development of fluid overload in 20.5% of the patients in the aggressive-resuscitation group versus 6.3% of those in the moderate-resuscitation group (adjusted relative risk, 2.85; 95% confidence interval, 1.36-5.94; P = .004).
“An increased risk of fluid overload was detected in the overall population of patients and also in subgroups of patients without systemic inflammatory response syndrome at baseline, patients with SIRS at baseline (thus, with a higher risk of development of severe pancreatitis), and patients with hypovolemia,” the investigators reported.
This clear signal of harm was coupled with no significant difference in the incidence of moderately severe or severe pancreatitis (22.1% in the aggressive-resuscitation group and 17.3% in the moderate-resuscitation group; aRR, 1.30; 95% CI, 0.78-2.18; P = .32).
Patients in the aggressive-resuscitation group spent a median of 6 days in the hospital, compared with 5 days for patients in the moderate-resuscitation group.
“These findings do not support current management guidelines, which recommend early aggressive resuscitation for the treatment of acute pancreatitis,” the study team wrote.
‘Landmark’ trial
This is a “landmark” trial and “so clinically relevant because of its choice of real world-appropriate aggressive-resuscitation and moderate-resuscitation treatment groups, its use of pancreatitis severity as the main clinical outcome, and its reliance on the carefully defined variable of fluid overload as the main safety outcome,” Dr. Gardner wrote in his editorial.
“Unlike in most other randomized, controlled trials of fluid resuscitation in acute pancreatitis, patients with varying baseline pancreatitis severity were included, and changes in the rate of resuscitation were determined on the basis of a dynamic assessment of hemodynamic testing, imaging, and clinical factors,” he added.
Dr. Gardner said the WATERFALL trial results lead to several conclusions.

Artemisia capillaris extract
Melasma is a difficult disorder to treat. With the removal of hydroquinone from the cosmetic market and the prevalence of dyschromia, new skin lightening ingredients are being sought and many new discoveries are coming from Asia.
There are more than 500 species of the genus Artemisia (of the Astraceae or Compositae family) dispersed throughout the temperate areas of Asia, Europe, and North America.1 Various parts of the shrub Artemisia capillaris, found abundantly in China, Japan, and Korea, have been used in traditional medicine in Asia for hundreds of years. A. capillaris (Yin-Chen in Chinese) has been deployed in traditional Chinese medicine as a diuretic, to protect the liver, and to treat skin inflammation.2,3 Antioxidant, anti-inflammatory, antisteatotic, antitumor, and antiviral properties have been associated with this plant,3 and hydrating effects have been recently attributed to it. In Korean medicine, A. capillaris (InJin in Korean) has been used for its hepatoprotective, analgesic, and antipyretic activities.4,5 In this column, the focus will be on recent evidence that suggests possible applications in skin care.
Chemical constituents
In 2008, Kim et al. studied the anticarcinogenic activity of A. capillaris, among other medicinal herbs, using the 7,12-dimethylbenz[a]anthracene (DMBA)-induced mouse skin carcinogenesis model. The researchers found that A. capillaris exhibited the most effective anticarcinogenic activity compared to the other herbs tested, with such properties ascribed to its constituent camphor, 1-borneol, coumarin, and achillin. Notably, the chloroform fraction of A. capillaris significantly lowered the number of tumors/mouse and tumor incidence compared with the other tested herbs.6
The wide range of biological functions associated with A. capillaris, including anti-inflammatory, antioxidant, antidiabetic, antisteatotic, and antitumor activities have, in various studies, been attributed to the bioactive constituents scoparone, scopoletin, capillarisin, capillin, and chlorogenic acids.3
Tyrosinase-related protein 1 (TYRP-1) and its role in skin pigmentation
Tyrosinase related protein 1 (TYRP-1) is structurally similar to tyrosinase, but its role is still being elucidated. Mutations in TYR-1 results in oculocutaneous albinism. TYRP-1 is involved in eumelanin synthesis, but not in pheomelanin synthesis. Mutations in TYRP-1 affect the quality of melanin synthesized rather than the quantity.4 TYRP-1 is being looked at as a target for treatment of hyperpigmentation disorders such as melasma.
Effects on melanin synthesis
A. capillaris reduces the expression of TYRP-1, making it attractive for use in skin lightening products. Although there are not a lot of data, this is a developing area of interest and the following will discuss what is known so far.
Kim et al. investigated the antimelanogenic activity of 10 essential oils, including A. capillaris, utilizing the B16F10 cell line model. A. capillaris was among four extracts found to hinder melanogenesis, and the only one that improved cell proliferation, displayed anti-H2O2 activity, and reduced tyrosinase-related protein (TRP)-1 expression. The researchers determined that A. capillaris extract suppressed melanin production through the downregulation of the TRP 1 translational level. They concluded that while investigations using in vivo models are necessary to buttress and validate these results, A. capillaris extract appears to be suitable as a natural therapeutic antimelanogenic agent as well as a skin-whitening ingredient in cosmeceutical products.7
Tabassum et al. screened A. capillaris for antipigmentary functions using murine cultured cells (B16-F10 malignant melanocytes). They found that the A. capillaris constituent 4,5-O-dicaffeoylquinic acid significantly and dose-dependently diminished melanin production and tyrosinase activity in the melanocytes. The expression of tyrosinase-related protein-1 was also decreased. Further, the researchers observed antipigmentary activity in a zebrafish model, with no toxicity demonstrated by either A. capillaris or its component 4,5-O-dicaffeoylquinic acid. They concluded that this compound could be included as an active ingredient in products intended to address pigmentation disorders.8
Anti-inflammatory activity
Inflammation is well known to trigger the production of melanin. This is why anti-inflammatory ingredients are often included in skin lighting products. A. capillaris displays anti-inflammatory activity and has shown some antioxidant activity.
In 2018, Lee et al. confirmed the therapeutic potential of A. capillaris extract to treat psoriasis in HaCaT cells and imiquimod-induced psoriasis-like mouse models. In the murine models, those treated with the ethanol extract of A. capillaris had a significantly lower Psoriasis Area and Severity Index score than that of the mice not given the topical application of the botanical. Epidermal thickness was noted to be significantly lower compared with the mice not treated with A. capillaris.9 Further studies in mice by the same team later that year supported the use of a cream formulation containing A. capillaris that they developed to treat psoriasis, warranting new investigations in human skin.10
Yeo et al. reported, earlier in 2018, on other anti-inflammatory activity of the herb, finding that the aqueous extract from A. capillaris blocked acute gastric mucosal injury by hindering reactive oxygen species and nuclear factor kappa B. They added that A. capillaris maintains oxidant/antioxidant homeostasis and displays potential as a nutraceutical agent for treating gastric ulcers and gastritis.5
In 2011, Kwon et al. studied the 5-lipoxygenase inhibitory action of a 70% ethanol extract of aerial parts of A. capillaris. They identified esculetin and quercetin as strong inhibitors of 5-lipoxygenase. The botanical agent, and esculetin in particular, robustly suppressed arachidonic acid-induced ear edema in mice as well as delayed-type hypersensitivity reactions. Further, A. capillaris potently blocked 5-lipoxygenase-catalyzed leukotriene synthesis by ionophore-induced rat basophilic leukemia-1 cells. The researchers concluded that their findings may partially account for the use of A. capillaris as a traditional medical treatment for cutaneous inflammatory conditions.2
Atopic dermatitis and A. capillaris
In 2014, Ha et al. used in vitro and in vivo systems to assess the anti-inflammatory effects of A. capillaris as well as its activity against atopic dermatitis. The in vitro studies revealed that A. capillaris hampered NO and cellular histamine synthesis. In Nc/Nga mice sensitized by Dermatophagoides farinae, dermatitis scores as well as hemorrhage, hypertrophy, and hyperkeratosis of the epidermis in the dorsal skin and ear all declined after the topical application of A. capillaris. Plasma levels of histamine and IgE also significantly decreased after treatment with A. capillaris. The investigators concluded that further study of A. capillaris is warranted as a potential therapeutic option for atopic dermatitis.11
Summary
Many botanical ingredients from Asia are making their way into skin care products in the USA. A. capillaris extract is an example and may have utility in treating hyperpigmentation-associated skin issues such as melasma. Its inhibitory effects on both inflammation and melanin production in addition to possible antioxidant activity make it an interesting compound worthy of more scrutiny.

Novel combination treatment improves function in early Parkinson’s disease
Results from a phase 3 trial found that P2B001 was superior to its components in improving motor symptoms and daily function and was comparable with marketed doses of pramipexole.
P2B001 also produced less daytime sleepiness and fewer dopaminergic effects, said the investigators, who presented findings at the International Congress of Parkinson’s Disease and Movement Disorders.
The treatment studied, P2B001, is a proprietary, fixed-dose combination of extended-release (ER) formulations of pramipexole and rasagiline. Neither dose is currently available on the market.
Investigators wanted to test the hypothesis that two anti-Parkinsonian drugs that act through different mechanisms could work synergistically, providing benefits comparable with pramipexole but with fewer side effects, said lead study author Warren Olanow, MD, professor emeritus in the neurology and neuroscience departments at the Icahn School of Medicine at Mount Sinai, New York.
Pramipexole is problematic in that it causes dopaminergic and sleep-related side effects.
Laboratory studies have shown that low doses of pramipexole and rasagiline act synergistically, said Dr. Olanow. “A previous double-blind controlled study demonstrated that P2B001 was significantly superior to placebo with respect to efficacy (P < .001) and had a good safety and tolerability profile.”
P2B001 outperforms other formulations
The multicenter phase 3 study (NCT03329508) enrolled 544 patients aged 35-80 with early Parkinson’s disease to assess efficacy and safety of a daily dose of P2B001, compared with its components. Patients were randomized 2:2:2:1 to 12 weeks of treatment with P2B001; pramipexole ER 0.6 mg; rasagiline ER 0.75 mg, or to a calibration arm of marketed pramipexole-ER titrated to optimal dose (mean dose, 3.2 mg).
The primary endpoint compared baseline with week 12 changes in Unified Parkinson’s Disease Rating Scale total scores for P2B001 versus its individual components. The secondary endpoint compared baseline changes in Epworth Sleepiness Scale (ESS) for P2B001 versus pramipexole-ER.
P2B001 showed superior efficacy to each of its individual components and comparable efficacy with marketed doses of pramipexole-ER. It also yielded fewer adverse events related to dopaminergic side effects and less daytime sleepiness as measured by ESS. “Further, the drug is administered once a day and does not require titration,” said Dr. Olanow.
Levodopa-related benefits
Another advantage of starting early-stage patients on P2B001 is that it would give patients more time to be on an effective therapy with fewer side effects before going on levodopa, the current gold standard for Parkinson’s disease treatment.
Although the American Academy of Neurology recommends levodopa as initial therapy for Parkinson’s disease, the drug has been associated with a risk of developing motor complications.
“This opinion, however, was formulated prior to the availability of the results of the P2B001 study and should be reassessed in the light of the present study,” said Dr. Olanow. Longer-term studies should assess when and if patients will require levodopa therapy, as well as the long-term effects of P2B001 on the development of motor complications in patients with early Parkinson’s disease patients.
Investigators are preparing a regulatory market approval filing for P2B001 with the Food and Drug Administration.
Dr. Olanow is CEO of Clintrex Research Corporation, which has provided services to Pharma2B, sponsor of the phase 3 study. Pharma Two B is a private, late clinical-stage pharmaceutical company in Rehovot, Israel, that owns worldwide granted patents for P2B001 pharmaceutical composition and method of treatment.

Pandemic has helped clinicians to gain better insight on pernio, expert says
PORTLAND, ORE. – while others are not, according to Lindy P. Fox, MD, professor of dermatology and director of the hospital consultation service at the University of California, San Francisco.
“We’re learning a lot about pernio because of COVID,” Dr. Fox, a member of the American Academy of Dermatology’s Ad Hoc Task Force on COVID-19, said at the annual meeting of the Pacific Dermatologic Association. “Patients with pernio tend to either have bright red or purple individual lesions or an erythromelalgia-like presentation, often waking up in the middle of the night saying ‘my feet hurt. I can’t put sheets over my feet.’ In my experience, the patients with an erythromelalgia-like presentation tend to be a lot harder to treat.”
Establishing terminology to describe pernio-like lesions was a challenge in the early stages of the COVID-19 pandemic, Dr. Fox added, with clinicians using terms like erythema multiforme-like, coxsackie-like, or even necrotic to describe the lesions. “I don’t think pernio is truly necrotic; I think it’s really inflammatory and purpuric,” she said.
Early in the pandemic, studies suggesting a link with these cases and COVID-19 infection include a case series of 318 patients with pernio-like skin lesions who had confirmed or suspected COVID-19. Most of these patients were generally young and healthy and most had relatively mild COVID-19; 7% were laboratory-confirmed COVID-19 positive, and 6% were close contacts of patients with confirmed COVID-19. Pernio-like lesions were the only symptoms in 55% of the patients.
In another study, researchers in France evaluated the clinical, laboratory, and pathologic characteristics of 40 patients who developed chilblain-like lesions (mostly involving the toes) during the COVID-19 pandemic and were seen as outpatients in April 2020 . All were polymerase chain reaction (PCR) negative, 30% were SARS-CoV-2 serology positive, and 60% had elevated D-dimers. Histology obtained from 19 of the patients revealed lymphocytic inflammation and vascular damage, and 8 had IgA positivity.
In a retrospective analysis of seven pediatric chilblains cases during the pandemic, researchers examined the skin biopsies to evaluate histopathological features and explored the presence of SARS-CoV-2 in the tissue. All patients were PCR negative. The authors observed cytoplasmic granular positivity for SARS-CoV-2 spike protein in endothelial cells, a feature that they said showed coronavirus-like particles, consistent with SARS-CoV-2.
Not all studies in the medical literature have demonstrated an association between pernio-like/chilblains-like lesions and COVID-19, though. An analysis of 23 patients, with skin eruptions considered associated with SARS-CoV-2 infections (including 21 cases of chilblains) during the first wave of the pandemic found that the antibody and T-cell response in patients with pandemic chilblains was the same as in negative controls.
“What’s remarkably interesting about this study is that they did autopsies of samples from patients who had died prepandemic, so there was no such thing as COVID-19,” said Dr. Fox, who was not involved with the study. “They stained for viral particles in those patients, and they were positive in a subset of patients. This makes me wonder about what the significance of that staining positivity is.”
Yet another group of investigators looked at what was happening with pernio during the waves of COVID in a study of chilblains cases in children in Spain, and found a stronger association between lockdown and cold temperature, which argues against a direct association between pernio and COVID infection.
In Dr. Fox’s experience, COVID toes can recur, especially upon exposure to cold. “What taught me this in real life is a patient who I saw remotely by video,” she recalled. “It was early on in the pandemic. I could not prove he had COVID no matter how hard I tried, but I do think he had COVID toes at that time.” When he later was confirmed to have COVID, “he got pernio in the same exact location as his original suspected COVID toes.”
According to an analysis of long COVID in the skin, based on cases reported to the American Academy of Dermatology–International League of Dermatological Societies registry from April 8 to Oct. 8, 2020, pernio-like lesions lasted a median of 12 days in patients with lab-confirmed COVID-19 and a median of 15 days in those with suspected COVID-19. But almost 7% of the 103 pernio cases were long-haulers, defined as those with dermatologic signs of COVID that lasted beyond 60 days.
“There are some patients who are resistant to treatment,” Dr. Fox said. “In addition, recurrent lesions make me think that maybe all pernio is triggered by some viral cause. This causes an immunologic phenomenon that’s responding to a viral trigger you’re trying to deal with. That may be the better way to think about COVID toes.”
Different variants of COVID also appear to be changing the characteristics of dermatologic manifestations associated with infection. Results from a large retrospective analysis of nearly 350,000 users of a COVID study App in the United Kingdom found that skin lesions were more predictive of a positive test in the Delta wave, compared with the Omicron wave, while pernio-like lesions were predictive of infection in the Delta wave but not in the Omicron wave.
“And, whether you were vaccinated or unvaccinated really did not influence whether or not you were going to have a skin rash as a presenting sign of COVID, except for the burning rash, which was less in vaccinated patients,” said Dr. Fox, who was not involved with the study.
Dr. Fox reported having no relevant disclosures.
