Biologic therapy for psoriasis may protect against severe COVID-19, according to two large observational studies from Italy and France presented at the virtual annual congress of the European Academy of Dermatology and Venereology.

“Biologics seem to be very protective against severe, poor-prognosis COVID-19, but they do not prevent infection with the virus,” reported Giovanni Damiani, MD, a dermatologist at the University of Milan.

This apparent protective effect of biologic agents against severe and even fatal COVID-19 is all the more impressive because the psoriasis patients included in the Italian study – as is true of those elsewhere throughout the world – had relatively high rates of obesity, smoking, and chronic obstructive pulmonary disease, known risk factors for severe COVID-19, he added.



He presented a case-control study including 1,193 adult psoriasis patients on biologics or apremilast (Otezla) at Milan’s San Donato Hospital during the period from Feb. 21 to April 9, 2020. The control group comprised more than 10 million individuals, the entire adult population of the Lombardy region, of which Milan is the capital. This was the hardest-hit area in all of Italy during the first wave of COVID-19.

Twenty-two of the 1,193 psoriasis patients experienced confirmed COVID-19 during the study period. Seventeen were quarantined at home because their disease was mild. Five were hospitalized. But no psoriasis patients were placed in intensive care, and none died.

Psoriasis patients on biologics were significantly more likely than the general Lombardian population to test positive for COVID-19, with an unadjusted odds ratio of 3.43. They were at 9.05-fold increased risk of home quarantine for mild disease, and at 3.59-fold greater risk than controls for hospitalization for COVID-19. However, they were not at significantly increased risk of ICU admission. And while they actually had a 59% relative risk reduction for death, this didn’t achieve statistical significance.

Forty-five percent of the psoriasis patients were on an interleukin-17 (IL-17) inhibitor, 22% were on a tumor necrosis factor–alpha inhibitor, and 20% were taking an IL-12/23 inhibitor. Of note, none of 77 patients on apremilast developed COVID-19, even though it is widely considered a less potent psoriasis therapy than the injectable monoclonal antibody biologics.

The French experience

Anne-Claire Fougerousse, MD, and her French coinvestigators conducted a study designed to address a different question: Is it safe to start psoriasis patients on biologics or older conventional systemic agents such as methotrexate during the pandemic?

She presented a French national cross-sectional study of 1,418 adult psoriasis patients on a biologic or standard systemic therapy during a snapshot in time near the peak of the first wave of the pandemic in France: the period from April 27 to May 7, 2020. The group included 1,188 psoriasis patients on maintenance therapy and 230 who had initiated systemic treatment within the past 4 months. More than one-third of the patients had at least one risk factor for severe COVID-19.

Although testing wasn’t available to confirm all cases, 54 patients developed probable COVID-19 during the study period. Only five required hospitalization. None died. The two hospitalized psoriasis patients admitted to an ICU had obesity as a risk factor for severe COVID-19, as did another of the five hospitalized patients, reported Dr. Fougerousse, a dermatologist at the Bégin Military Teaching Hospital in Saint-Mandé, France. Hospitalization for COVID-19 was required in 0.43% of the French treatment initiators, not significantly different from the 0.34% rate in patients on maintenance systemic therapy. A study limitation was the lack of a control group.

Nonetheless, the data did answer the investigators’ main question: “This is the first data showing no increased incidence of severe COVID-19 in psoriasis patients receiving systemic therapy in the treatment initiation period compared to those on maintenance therapy. This may now allow physicians to initiate conventional systemic or biologic therapy in patients with severe psoriasis on a case-by-case basis in the context of the persistent COVID-19 pandemic,” Dr. Fougerousse concluded.


 

 

 

Proposed mechanism of benefit

The Italian study findings that biologics boost the risk of infection with the SARS-CoV-2 virus in psoriasis patients while potentially protecting them against ICU admission and death are backed by a biologically plausible albeit as yet unproven mechanism of action, Dr. Damiani asserted.

He elaborated: A vast body of high-quality clinical trials data demonstrates that these targeted immunosuppressive agents are associated with modestly increased risk of viral infections, including both skin and respiratory tract infections. So there is no reason to suppose these agents would offer protection against the first phase of COVID-19, involving SARS-CoV-2 infection, nor protect against the second (pulmonary phase), whose hallmarks are dyspnea with or without hypoxia. But progression to the third phase, involving hyperinflammation and hypercoagulation – dubbed the cytokine storm – could be a different matter.

“Of particular interest was that our patients on IL-17 inhibitors displayed a really great outcome. Interleukin-17 has procoagulant and prothrombotic effects, organizes bronchoalveolar remodeling, has a profibrotic effect, induces mitochondrial dysfunction, and encourages dendritic cell migration in peribronchial lymph nodes. Therefore, by antagonizing this interleukin, we may have a better prognosis, although further studies are needed to be certain,” Dr. Damiani commented.
 

Publication of his preliminary findings drew the attention of a group of highly respected thought leaders in psoriasis, including James G. Krueger, MD, head of the laboratory for investigative dermatology and codirector of the center for clinical and investigative science at Rockefeller University, New York.

The Italian report prompted them to analyze data from the phase 4, double-blind, randomized ObePso-S study investigating the effects of the IL-17 inhibitor secukinumab (Cosentyx) on systemic inflammatory markers and gene expression in psoriasis patients. The investigators demonstrated that IL-17–mediated inflammation in psoriasis patients was associated with increased expression of the angiotensin-converting enzyme 2 (ACE2) receptor in lesional skin, and that treatment with secukinumab dropped ACE2 expression to levels seen in nonlesional skin. Given that ACE2 is the chief portal of entry for SARS-CoV-2 and that IL-17 exerts systemic proinflammatory effects, it’s plausible that inhibition of IL-17–mediated inflammation via dampening of ACE2 expression in noncutaneous epithelia “could prove to be advantageous in patients with psoriasis who are at risk for SARS-CoV-2 infection,” according to Dr. Krueger and his coinvestigators in the Journal of Allergy and Clinical Immunology.

Dr. Damiani and Dr. Fougerousse reported having no financial conflicts regarding their studies. The secukinumab/ACE2 receptor study was funded by Novartis.

Mirikizumab beats placebo, secukinumab for psoriasis

The investigational monoclonal antibody mirikizumab performed more robustly against placebo overall – and the interleukin-17 inhibitor secukinumab at key endpoints – for treatment of moderate to severe psoriasis, according to new long-term OASIS-2 trial data.

Dr. Kim A. Papp of Probity Medical Research
Dr. Kim A. Papp

Both doses of mirikizumab in the international, double-blind trial achieved improvements in Psoriasis Area and Severity Index (PASI) scores in larger numbers of participants at week 52 than secukinumab (Cosentyx), with low adverse event rates.

If approved, mirikizumab, which binds the p19 subunit of IL-23, would join three other IL-23 drugs already marketed in the United States for moderate to severe psoriasis, said OASIS-2 lead investigator Kim A. Papp, MD, PhD, founder and president of Probity Medical Research in Waterloo, Ont.

But Dr. Papp feels larger studies “will be necessary to put these data into perspective,” he said during a presentation at the virtual annual European Academy of Dermatology and Venereology Congress.

“Probably the most important takeaway here is that we may have another option to choose from,” Dr. Papp said in an interview. “People tend to think we have an adequate stable of treatment options, and I would argue we do not.”

“There are variations over time that occur in terms of an individual’s biological response, and the consequence is that nothing we have works for everyone, and nothing we have works forever,” he added. Psoriasis biologics “are increasingly competent, compared to medications we had even 5 or 10 years ago ... but they still don’t satisfy all our needs, so we do need to keep replenishing our stock.”

The multicenter trial included 1,465 patients who were randomly split into four groups. Subcutaneously, one group received 250 mg of mirikizumab every 4 weeks, and then 250 mg of the drug every 8 weeks starting at week 16. Another group received 250 mg of mirikizumab every 4 weeks and then 125 mg every 8 weeks starting at week 16.

The third group received 300 mg of secukinumab weekly for 4 weeks and then every 4 weeks starting at week 4. The last group received placebo every 4 weeks, and then 250 mg of mirikizumab every 4 weeks from week 16 to 32 and every 8 weeks thereafter.

Primary endpoints measured the percentage of patients achieving a static Physician’s Global Assessment (sPGA) of 0 or 1, with an improvement of at least 2 points from baseline; and the proportion of patients with PASI 90 at week 16, compared with placebo.

Major secondary endpoints were PASI 75 and PASI 100, compared with placebo at week 16; an sPGA of 0 or 1 and PASI 90 noninferiority, compared with secukinumab at week 16; and sPGA of 0 or 1, PASI 90, and PASI 100 superiority, compared with secukinumab at week 52.

More than 91% of participants completed all 52 weeks in the trial. Mirikizumab met primary endpoints compared with placebo and major secondary endpoints vs secukinumab at week 16 (P < .001). PASI 90 and sPGA (0,1) response rates far exceeded placebo for both 250 mg mirikizumab (74.4% and 79.7%, respectively) and secukinumab (72.8% and 76.3%, respectively).



At week 52, major secondary endpoints for both mirikizumab doses were superior to secukinumab (all P < .001). PASI 90 was achieved by 81.4% of 125 mg and 82.4% of 250 mg mirikizumab patients versus 69.4% of secukinumab patients; sPGA (0,1) by 83.1% of 125 mg and 83.3% of 250 mg mirikizumab patients versus 68.5% of secukinumab patients; and PASI 100 by 53.9% of 125 mg and 58.8% of 250 mg mirikizumab patients versus 42.9% of secukinumab patients.

Treatment-associated adverse effects were similar across all treatment groups and study periods. The most common were nasopharyngitis, upper respiratory tract infectionheadacheback pain, and arthralgia. But serious adverse effects were minimal, Dr. Papp said. One death occurred in a mirikizumab patient from acute MI, which was deemed unrelated to the study drug.

Myrto Georgia Trakatelli, MD, PhD, from Aristotle University of Thessaloniki (Greece), said the results indicate that dermatologists “should not be afraid to use” mirikizumab long term if it is approved by the Food and Drug Administration.

“Sometimes patients use many treatments for a long time and all of a sudden, they stop working,” Dr. Trakatelli said in an interview. “A new biologic is always welcome because we do see patients not responding to other treatment.”

But Dr. Trakatelli said “a point that troubled me in the study” was that mirikizumab was compared with an IL-17 inhibitor “instead of a molecule targeting IL-23, such as guselkumab [Tremfya], for example.”

“I would have liked to see a head-to-head comparison with a molecule that blocks the same target,” said Dr. Trakatelli, chair of the EADV education committee.

Dr. Papp countered that “there are various reasons for running comparator studies.” Secukinumab, he said, “was the market leader and was widely used, so it makes sense that one is going to compare against a product as the market lead.”

“Not to say there won’t be future studies” in which mirikizumab is compared “head to head with IL-23s,” Dr. Papp added.

But larger patient numbers and longer treatment times are still needed with mirikizumab “to characterize the level of response, duration of response, and any adverse event profiles,” Dr. Papp stressed.

“One study does not a drug make,” he said. “It’s just exciting that we still have things to offer. This is an important example, and of course opportunity, for patients.”

The trial was funded by Lilly. Dr. Papp disclosed financial relationships with AbbVie, Amgen, Astellas, Valeant, Baxalta, Baxter, Boehringer Ingelheim, Bristol-Myers Squibb, Celgene, Coherus, Dermira, Forward Pharma, Galderma, Genentech, GlaxoSmithKline, Janssen, Kyowa Kirin, LEO Pharma, Lilly, Medimmune, Merck, Novartis, Pfizer, Regeneron, Roche, Sanofi Genzyme, Stiefel, Sun Pharma, Takeda, and UCB.

The investigational monoclonal antibody mirikizumab performed more robustly against placebo overall – and the interleukin-17 inhibitor secukinumab at key endpoints – for treatment of moderate to severe psoriasis, according to new long-term OASIS-2 trial data.

Both doses of mirikizumab in the international, double-blind trial achieved improvements in Psoriasis Area and Severity Index (PASI) scores in larger numbers of participants at week 52 than secukinumab (Cosentyx), with low adverse event rates.

If approved, mirikizumab, which binds the p19 subunit of IL-23, would join three other IL-23 drugs already marketed in the United States for moderate to severe psoriasis, said OASIS-2 lead investigator Kim A. Papp, MD, PhD, founder and president of Probity Medical Research in Waterloo, Ont.

But Dr. Papp feels larger studies “will be necessary to put these data into perspective,” he said during a presentation at the virtual annual European Academy of Dermatology and Venereology Congress.

“Probably the most important takeaway here is that we may have another option to choose from,” Dr. Papp said in an interview. “People tend to think we have an adequate stable of treatment options, and I would argue we do not.”

“There are variations over time that occur in terms of an individual’s biological response, and the consequence is that nothing we have works for everyone, and nothing we have works forever,” he added. Psoriasis biologics “are increasingly competent, compared to medications we had even 5 or 10 years ago ... but they still don’t satisfy all our needs, so we do need to keep replenishing our stock.”

The multicenter trial included 1,465 patients who were randomly split into four groups. Subcutaneously, one group received 250 mg of mirikizumab every 4 weeks, and then 250 mg of the drug every 8 weeks starting at week 16. Another group received 250 mg of mirikizumab every 4 weeks and then 125 mg every 8 weeks starting at week 16.

The third group received 300 mg of secukinumab weekly for 4 weeks and then every 4 weeks starting at week 4. The last group received placebo every 4 weeks, and then 250 mg of mirikizumab every 4 weeks from week 16 to 32 and every 8 weeks thereafter.

Primary endpoints measured the percentage of patients achieving a static Physician’s Global Assessment (sPGA) of 0 or 1, with an improvement of at least 2 points from baseline; and the proportion of patients with PASI 90 at week 16, compared with placebo.

Major secondary endpoints were PASI 75 and PASI 100, compared with placebo at week 16; an sPGA of 0 or 1 and PASI 90 noninferiority, compared with secukinumab at week 16; and sPGA of 0 or 1, PASI 90, and PASI 100 superiority, compared with secukinumab at week 52.

More than 91% of participants completed all 52 weeks in the trial. Mirikizumab met primary endpoints compared with placebo and major secondary endpoints vs secukinumab at week 16 (P < .001). PASI 90 and sPGA (0,1) response rates far exceeded placebo for both 250 mg mirikizumab (74.4% and 79.7%, respectively) and secukinumab (72.8% and 76.3%, respectively).



At week 52, major secondary endpoints for both mirikizumab doses were superior to secukinumab (all P < .001). PASI 90 was achieved by 81.4% of 125 mg and 82.4% of 250 mg mirikizumab patients versus 69.4% of secukinumab patients; sPGA (0,1) by 83.1% of 125 mg and 83.3% of 250 mg mirikizumab patients versus 68.5% of secukinumab patients; and PASI 100 by 53.9% of 125 mg and 58.8% of 250 mg mirikizumab patients versus 42.9% of secukinumab patients.

Treatment-associated adverse effects were similar across all treatment groups and study periods. The most common were nasopharyngitis, upper respiratory tract infectionheadacheback pain, and arthralgia. But serious adverse effects were minimal, Dr. Papp said. One death occurred in a mirikizumab patient from acute MI, which was deemed unrelated to the study drug.

Myrto Georgia Trakatelli, MD, PhD, from Aristotle University of Thessaloniki (Greece), said the results indicate that dermatologists “should not be afraid to use” mirikizumab long term if it is approved by the Food and Drug Administration.

“Sometimes patients use many treatments for a long time and all of a sudden, they stop working,” Dr. Trakatelli said in an interview. “A new biologic is always welcome because we do see patients not responding to other treatment.”

But Dr. Trakatelli said “a point that troubled me in the study” was that mirikizumab was compared with an IL-17 inhibitor “instead of a molecule targeting IL-23, such as guselkumab [Tremfya], for example.”

“I would have liked to see a head-to-head comparison with a molecule that blocks the same target,” said Dr. Trakatelli, chair of the EADV education committee.

Dr. Papp countered that “there are various reasons for running comparator studies.” Secukinumab, he said, “was the market leader and was widely used, so it makes sense that one is going to compare against a product as the market lead.”

“Not to say there won’t be future studies” in which mirikizumab is compared “head to head with IL-23s,” Dr. Papp added.

But larger patient numbers and longer treatment times are still needed with mirikizumab “to characterize the level of response, duration of response, and any adverse event profiles,” Dr. Papp stressed.

“One study does not a drug make,” he said. “It’s just exciting that we still have things to offer. This is an important example, and of course opportunity, for patients.”

The trial was funded by Lilly. Dr. Papp disclosed financial relationships with AbbVie, Amgen, Astellas, Valeant, Baxalta, Baxter, Boehringer Ingelheim, Bristol-Myers Squibb, Celgene, Coherus, Dermira, Forward Pharma, Galderma, Genentech, GlaxoSmithKline, Janssen, Kyowa Kirin, LEO Pharma, Lilly, Medimmune, Merck, Novartis, Pfizer, Regeneron, Roche, Sanofi Genzyme, Stiefel, Sun Pharma, Takeda, and UCB.

Hand eczema: Pan-JAK inhibitor delgocitinib shows dose-dependent response in phase 2b trial

Delgocitinib cream shows a dose-dependent response in easing chronic hand eczema, a common and difficult-to-treat disorder for which few other topical options are available, a new international phase 2b research suggests.

An investigational pan–Janus kinase inhibitor that blocks all four members of the JAK family, twice-daily delgocitinib doses of 8 mg/g and 20 mg/g demonstrated the highest efficacy in adults with mild to severe chronic hand eczema. By week 16, nearly 40% of patients receiving either dose were clear or almost clear of symptoms.

“By mode of action, we think delgocitinib is more selective in the way of acting,” said lead investigator Margitta Worm, MD, PhD, of the department of dermatology, venereology, and allergology at Charité University Hospital in Berlin, during a presentation of the results at the virtual annual congress of the European Academy of Dermatology and Venereology.

“We do know that JAKs play an important role in chronic inflammation and interfering with the JAK pathway can have anti-inflammatory effects,” Dr. Worm said in an interview. “Whenever it’s possible to use a molecule topically or locally, it’s advantageous for patients because it’s only acting where you apply it and there are no systemic side effects.”

Defined as lasting more than 3 months or relapsing twice or more within a year, chronic hand eczema is a particularly problematic form of atopic dermatitis because “we need our hands every day for almost every activity, so having eczema on your hands has a huge impact on quality of life,” Dr. Worm said.

Many people whose hands are integral to their occupations also have trouble working because of the disorder, she explained. But current topical treatments are limited to emollients, corticosteroids, and calcineurin inhibitors.

“Topical corticosteroids are efficacious, but can cause skin atrophy,” she said. “Their long-term side-effect profile limits their use.”

The number of patients in each treatment group was too small to focus on different subtypes of chronic hand eczema, “but this is something that will probably be looked at in the future,” Dr. Worm said. “At the moment it’s nice to see a dose-dependent clinical efficacy and good tolerability, and now we have to wait for phase 3 data in the future.”

Dr. Worm and colleagues aimed to establish the dose-response relationship of twice-daily applications of delgocitinib cream in doses of 1, 3, 8, and 20 mg/g and a delgocitinib cream vehicle for 16 weeks. The 258 participants (61% women; average age, 46 years) were randomly assigned in equal groups to each dose of delgocitinib cream or the vehicle cream twice daily at centers in Denmark, Germany, and the United States.



The primary endpoint for the double-blind, 26-center trial was the proportion of patients who achieved an Investigator’s Global Assessment score of 0 (“clear”) or 1 (“almost clear”), with a 2-point or higher improvement from baseline over the study period. A key secondary endpoint was a change in the Hand Eczema Severity Index (HECSI) from baseline to week 16.

At week 16, a statistically significant dose response was established for both primary and secondary endpoints (P < .025). More patients in the delgocitinib 8-mg/g and 20-mg/g groups met the primary endpoint (36.5% and 37.7%, respectively) than patients in the 1-mg/g and 3-mg/g groups (21.2% and 7.8%, respectively) and vehicle group (8%, P = .0004).

This primary skin clearance effect at week 16 was demonstrated from week 4 in the 8-mg/g group and week 6 in the 20-mg/g group. But all active doses achieved a statistically significant greater jump in HECSI from baseline to week 16 than the vehicle cream (P < .05).

“The strength of the trial is that there were different concentrations of the substance used,” Dr. Worm said. “When you look to the results, you can demonstrate a dose-dependent clinical efficacy. This is of great value to really compare the efficacy of single doses.”

Most adverse events reported were not considered treatment related and were mild or moderate. The most frequently reported side effects were nasopharyngitis, eczema, and headache.

Commenting on the results, Asli Bilgic, MD, from Akdeniz University in Antalya, Turkey, who was not involved with the study, said that phase 3 studies of delgocitinib should probe further into the effects of the 8-mg/g dosage in this patient group since it appears to show similar efficacy and safety to 20 mg/g.

It’s important for research to focus on hand eczema “because it’s a very common disease, and treatment options are really sparse,” Dr. Bilgic said in an interview.

“Especially in the COVID era, many health care professionals, along with cleaning, catering, and mechanical jobs” are essential workers affected by the condition, she said. “It affects people’s self-esteem and their ability to do their job.”

The study was funded by LEO Pharma. Dr. Worm received lecture honoraria from LEO Pharma. Dr. Bilgic disclosed no relevant financial relationships.

No lab monitoring needed in adolescents on dupilumab

No clinically meaningful changes in laboratory values occurred in adolescents during 52 weeks on dupilumab for atopic dermatitis in a large, open-label safety study, Michael J. Cork, MBBS, PhD, reported at the virtual annual congress of the European Academy of Dermatology and Venereology.

These reassuring results from the ongoing LIBERTY AD PED-OLE study confirm that, as previously established in adults, no blood monitoring is required in adolescents on the monoclonal antibody, which inhibits signaling of interleukins-4 and -13, said Dr. Cork, professor of dermatology and head of Sheffield Dermatology Research at the University of Sheffield (England).

“The practical importance of this finding is that there are no other systemic drugs available that don’t require blood samples. Cyclosporine, methotrexate, and the others used for atopic dermatitis require a lot of blood monitoring, and they’re off-license anyway for use in children and adolescents,” he said in an interview.

Many pediatric patients are afraid of needles and have an intense dislike of blood draws. And in a pandemic, no one wants to come into the office for blood draws if they don’t need to.

“Blood draws are very different from the injection for dupilumab. Taking a blood sample is much more painful for children. The needle in the autoinjector is really, really tiny; you can hardly feel it, and with the autoinjector you can’t even see it,” noted Dr. Cork, who is both a pediatric and adult dermatologist.

This report from the ongoing LIBERTY AD PED-OLE study included 105 patients aged 12-17 years who completed 52 weeks on dupilumab (Dupixent) with assessments of hematologic and serum chemistry parameters at baseline and weeks 16 and 52.

“The results were anticipated, but we want to know the drug is safe in every age group. The immune system is different in different age groups, so we have to be really careful,” Dr. Cork said.



The clinical side-effect profile was the same as in adults, consisting mainly of mild conjunctivitis and injection-site reactions. It’s a much less problematic side effect picture than with the older drugs.

“We’re finding the conjunctivitis to be slightly less severe than in adults, maybe because we’ve learned from the first trials in adults and from clinical experience to use prophylactic therapy. There would be no child going on dupilumab now – and no adult – that I wouldn’t put on prophylactic eye drops with replacement tears. I start them 2 weeks before I start dupilumab,” the dermatologist explained.

He and others with extensive experience using the biologic agent also work closely with an ophthalmologist.

“If we see an eye problem before going on dupilumab we get an assessment and then ophthalmologic monitoring during treatment,” Dr. Cork said.

As a dermatologist specializing in atopic dermatitis, he confessed to feeling deprived over the years as he watched the multitude of targeted biologic agents being developed for psoriasis. When he became involved in the first pediatric clinical trials of dupilumab, he had a realization: “It’s a miraculous treatment.”

“The first child I put on dupilumab spent 70 days in the hospital for IV antibiotics in the prior year. Seventy days! He almost died from MRSA septicemia. His serum IgE was 155,000 kU/L. And his IgE just went down and down and down as the dupilumab took effect. It was just incredible,” he recalled.

Dr. Cork reported receiving research funding from and serving as a consultant to Sanofi and Regeneron, which fund the LIBERTY AD PED-OLE study, as well as numerous other pharmaceutical companies.

As a dermatologist specializing in atopic dermatitis, he confessed to feeling deprived over the years as he watched the multitude of targeted biologic agents being developed for psoriasis. When he became involved in the first pediatric clinical trials of dupilumab, he had a realization: “It’s a miraculous treatment.”

“The first child I put on dupilumab spent 70 days in the hospital for IV antibiotics in the prior year. Seventy days! He almost died from MRSA septicemia. His serum IgE was 155,000 kU/L. And his IgE just went down and down and down as the dupilumab took effect. It was just incredible,” he recalled.

Dr. Cork reported receiving research funding from and serving as a consultant to Sanofi and Regeneron, which fund the LIBERTY AD PED-OLE study, as well as numerous other pharmaceutical companies.

Skin symptoms common in COVID-19 ‘long-haulers’

A small subset of SARS-CoV-2 patients with “COVID toes” can be categorized as COVID-19 long-haulers, with skin symptoms sometimes enduring for more than 150 days, a new analysis revealed.

Evaluating data from an international registry of COVID-19 patients with dermatologic symptoms, researchers found that retiform purpura rashes are linked to severe COVID-19, with 100% of these patients requiring hospitalization and 82% experiencing acute respiratory distress syndrome (ARDS).

Meanwhile, pernio/chilblains rashes, dubbed “COVID toes,” are associated with milder disease and a 16% hospitalization rate. For all COVID-19–related skin symptoms, the average duration is 12 days.

“The skin is another organ system that we didn’t know could have long COVID” effects, said principal investigator Esther Freeman, MD, PhD, of the department of dermatology, Massachusetts General Hospital, Boston.

“The skin is really a window into how the body is working overall, so the fact that we could visually see persistent inflammation in long-hauler patients is particularly fascinating and gives us a chance to explore what’s going on,” Dr. Freeman said in an interview. “It certainly makes sense to me, knowing what we know about other organ systems, that there might be some long-lasting inflammation” in the skin as well.

The study is a result of the collaboration between the American Academy of Dermatology and the International League of Dermatological Societies, the international registry launched this past April. While the study included provider-supplied data from 990 cases spanning 39 countries, the registry now encompasses more than 1,000 patients from 41 countries, Dr. Freeman noted.

Dr. Freeman presented the data at the annual congress of the European Academy of Dermatology and Venereology.

Many studies have reported dermatologic effects of COVID-19 infection, but information was lacking about duration. The registry represents the largest dataset to date detailing these persistent skin symptoms and offers insight about how COVID-19 can affect many different organ systems even after patients recover from acute infection, Dr. Freeman said.

Eight different types of skin rashes were noted in the study group, of which 303 were lab-confirmed or suspected COVID-19 patients with skin symptoms. Of those, 224 total cases and 90 lab-confirmed cases included information on how long skin symptoms lasted. Lab tests for SARS-CoV-2 included polymerase chain reaction and serum antibody assays.

Dr. Freeman and associates defined “long-haulers” as patients with dermatologic symptoms of COVID-19 lasting 60 days or longer. These “outliers” are likely more prevalent than the registry suggests, she said, since not all providers initially reporting skin symptoms in patients updated that information over time.

“It’s important to understand that the registry is probably significantly underreporting the duration of symptoms and number of long-hauler patients,” she explained. “A registry is often a glimpse into a moment in time to these patients. To combat that, we followed up by email twice with providers to ask if patients’ symptoms were still ongoing or completed.”

Results showed a wide spectrum in average duration of symptoms among lab-confirmed COVID-19 patients, depending on specific rash. Urticaria lasted for a median of 4 days; morbilliform eruptions, 7 days; pernio/chilblains, 10 days; and papulosquamous eruptions, 20 days, with one long-hauler case lasting 70 days.

Five patients with pernio/chilblains were long-haulers, with toe symptoms enduring 60 days or longer. Only one went beyond 133 days with severe pernio and fatigue.

“The fact that we’re not necessarily seeing these long-hauler symptoms across every type of skin rash makes sense,” Dr. Freeman said. “Hives, for example, usually comes on acutely and leaves pretty rapidly. There are no reports of long-hauler hives.”

“That we’re really seeing these long-hauler symptoms in certain skin rashes really suggests that there’s a certain pathophysiology going in within that group of patients,” she added.

Dr. Freeman said not enough data have yet been generated to correlate long-standing COVID-19 skin symptoms with lasting cardiac, neurologic, or other symptoms of prolonged inflammation stemming from the virus.

Meanwhile, an EADV survey of 490 dermatologists revealed that just over one-third have seen patients presenting with skin signs of COVID-19. Moreover, 4% of dermatologists themselves tested positive for the virus.

Dr. Freeman encouraged all frontline clinicians assessing COVID-19 patients with skin symptoms to enter patients into the registry. But despite its strengths, the registry “can’t tell us what percentage of everyone who gets COVID will develop a skin finding or what percentage will be a long-hauler,” she said.

“A registry doesn’t have a denominator, so it’s like a giant case series,” she added.

“It will be very helpful going forward, as many places around the world experience second or third waves of COVID-19, to follow patients prospectively, acknowledge that patients will have symptoms lasting different amounts of time, and be aware these symptoms can occur on the skin,” she said.

Christopher Griffiths, MD, of the University of Manchester (England), praised the international registry as a valuable tool that will help clinicians better manage patients with COVID-19–related skin effects and predict prognosis.

“This has really brought the international dermatology community together, working on a focused goal relevant to all of us around the world,” Dr. Griffiths said in an interview. “It shows the power of communication and collaboration and what can be achieved in a short period of time.”

Dr. Freeman and Dr. Griffiths disclosed no relevant financial relationships.
