Psoriasis

VANCOUVER – Tumor necrosis factor inhibitor–induced psoriasiform dermatitis can occur in pediatric patients after any length of treatment, with documented cases emerging after the very first dose and as late as 63 months into anti-TNF therapy, Dr. Amy S. Paller said at the World Congress of Dermatology.

Histopathologically, this medication-induced condition is psoriasis. But it tends to follow a distinctive pattern, favoring the scalp, dorsal hands and feet, nails, and periorificial skin. Palmoplantar pustulosis is not uncommon. The lesions are often secondarily infected with Staphylococcus aureus, according to Dr. Paller, professor and chair of the department of dermatology and professor of pediatrics at Northwestern University in Chicago.

The phenomenon was first described in adults. But in the past several years, as the use of tumor necrosis factor (TNF) antagonists has gained increasing traction for treatment of pediatric inflammatory bowel disease and rheumatologic diseases, the dermatologic disorder has become better characterized in youths. In a retrospective study at McMaster Children’s Hospital in Hamilton, Ont., 17 of 172 (10%) infliximab-treated patients with Crohn’s disease developed new-onset psoriasis and another (0.6%) experienced worsening of preexisting psoriasis after anywhere from 1 to 25 infusions. Most patients responded well to topical steroids; however, three discontinued the biologic because of this complication (J Pediatr Gastroenterol Nutr. 2013 May;56[5]:512-8).

It’s now clear that the emergence of TNF inhibitor–induced psoriasis does not adversely affect the response of a patient’s inflammatory bowel disease or juvenile arthritis to the biologic. Also, the risk of recurrent psoriatic eruption is not reduced by concurrent methotrexate.

Researchers find TNF inhibitor–induced psoriasis to be an intriguing puzzle because of its paradoxical nature. After all, the TNF inhibitors are a highly effective treatment for moderate to severe plaque psoriasis. The leading theory as to the underlying basis for TNF inhibitor–induced psoriasis is that it may have a genetic basis, Dr. Paller noted.

The McMaster group found that their pediatric Crohn’s disease patients who developed psoriasis in conjunction with infliximab (Remicade) therapy were more likely than disease-matched controls to be homozygous for one of several specific polymorphisms in the interleukin-23R gene. And investigators at the University of Helsinki have reported that children with inflammatory bowel disease who developed psoriasiform dermatitis while on infliximab only rarely possessed the HLA-Cw*0602 genotype, which is commonly associated with psoriasis (Inflamm Bowel Dis. 2014 Aug;20[8]:1309-15).

The possibility of streptococcal or staphylococcal infection serving as a trigger for TNF inhibitor–induced psoriasis is also being explored, according to Dr. Paller.

Interviewing patients who live with psoriasis can reveal important information not included in psoriasis severity measures, according to Dr. David Pariser of Eastern Virginia Medical School, Norfolk, and his associates.

More than 90% of 101 patients with moderate to severe plaque psoriasis, with and without psoriatic arthritis, reported emotional and social impacts to their lives. Social impacts included avoiding/changing activities, relationships, or trying new things. Emotional impacts included a sense of anger, frustration, embarrassment, and self-consciousness; a lowered sense of self-esteem was common. Patients reported impacts in family, professional, social, and educational areas.

Patients with psoriasis and psoriatic arthritis tended to report both symptoms and well-being complications more often, with 77% reporting physical impacts and 34% reporting educational impacts, compared with 38% and 17%, respectively, for those with psoriasis only.

The study data “provide practitioners with deep insight into how patients with moderate to severe psoriasis are suffering, regardless of whether the concerns are elucidated during patient visits. The burdens in patients’ lives support the use of effective treatment; indeed, patients expressed how they value physicians who are knowledgeable about psoriasis and who will try various therapies,” the investigators concluded.

Attitudes toward psoriasis and herpes are significantly more stigmatizing than are perceptions of other dermatologic conditions, reported Dr. Jessica M. Donigan and her associates from Massachusetts General Hospital in Boston.

In a survey of 56 adults without any skin conditions aside from typical teenage acne, investigators used an image-based questionnaire to assess attitudes toward psoriasis, compared with other skin conditions such as atopic dermatitis, acne, vitiligo, rosacea, herpes labialis, warts, and tinea versicolor. At least 48% of respondents reported feeling upset by images of psoriasis, although significantly more were upset by images of herpes. Additionally, about 61% believed psoriasis had an infectious cause, with 41% of participants thinking psoriasis lesions looked contagious because of scale, color, and size, the authors reported.

A total of 39% of respondents thought herpes was the most-bothersome skin disease, compared with 30% for psoriasis, although this difference was not significant (P = .42). As many as 86% said they would feel pity if they saw a person with psoriasis, which was significantly greater for any of the other dermatologic conditions except acne, the investigators said.

The findings suggest that “misconceptions of infection and contagion, and feelings of pity cause psoriasis to be as bothersome as herpes labialis,” Dr. Donigan and her colleagues said.

Additionally, despite participants perceiving the two conditions as similarly bothersome, psoriasis may “have a greater overall impact on quality of life because of its continuity and chronicity,” they said. “Because of its potential lifelong impact, it is important to familiarize the public with psoriasis to aid in destigmatization.”

Patients with psoriasis are at increased risk of arrhythmia, with the risk even greater for younger patients and those with psoriatic arthritis, according to a population-based cohort study conducted in Taiwan.

Dr. Hsien-Yi Chiu of National Taiwan University and Wei-Lun Chang of National Yang-Ming University, both in Taipei, and their colleagues, looked at records from 40,637 patients diagnosed with psoriasis and 162,548 age- and sex-matched controls without psoriasis, over a mean follow-up of about 6 years, for the incidence of arrhythmias over a mean of 6 years.

In an article published in the September issue of the Journal of the American Academy of Dermatology, the investigators reported that those patients with psoriasis were at a significantly higher risk of developing arrhythmia, independent of traditional cardiovascular risk factors (adjusted hazard ratio, 1.34; 95% confidence interval, 1.29-1.39). Increased risk for patients with mild disease (aHR,1.35; 95% CI, 1.30-1.41) was comparable to that of patients with severe disease (aHR, 1.25; 95% CI 1.12-1.39) and more pronounced in the subgroup of patients with psoriatic arthritis (aHR, 1.46; 95% CI, 1.22-1.74). Younger patients, between aged 20 and 39 years, were at a higher risk (aHR, 1.39; 95% CI, 1.26-1.54) than older patients in the cohort (J Am Acad Dermatol. 2015 Sep;73:429-38).

Although previous studies have shown severe psoriasis to be associated with a nearly 60% increase in cardiovascular morbidity and mortality beyond traditional risk factors, less is known about arrhythmias specifically. “Inflammation may contribute to the alteration of cardiomyocyte electrophysiology, such as dysregulation of ion channel function, leading to increased risk of arrhythmia,” the investigators wrote.

The authors noted that limitations of their study were the potential surveillance bias for psoriasis patients due to increased hospital visits, and the fact that alcohol and tobacco use was not captured in the patient data. Treatment with systemic therapies may lower cardiovascular risk in psoriasis patients, they added, which may have explained why the arrhythmia risk among patients with severe disease was similar to those with mild disease.

The findings indicate “that psoriasis can be added to future risk-stratification scores for arrhythmia,” the investigators wrote, adding that patients with psoriasis, “especially young patients and those with PsA [psoriatic arthritis] , should be more closely screened for various types of arrhythmia,” with the hope of earlier intervention leading to reduction of cardiovascular morbidity and mortality.

PARK CITY, UTAH – Dr. John J. Zone first began to study gluten sensitivity in 1977, an interest that left some of his clinician colleagues wondering why.

“Everybody told me I was crazy – that this was extremely rare. So I always say I was gluten when gluten wasn’t cool,” Dr. Zone, professor and chairman of dermatology at the University of Utah, Salt Lake City, told attendees at the annual meeting of the Pacific Dermatologic Association.

These days, it’s hard to shop in a food market without noticing all the gluten-free foods available, from pizza dough to beer. Many restaurants also serve gluten-free dishes. But is it hype, or is gluten sensitivity that common? Five percent of people in the United States “will say they are gluten sensitive,” he said. “In fact, 1% of Caucasians actually have celiac disease and 1% of Caucasians have gluten sensitivity that can be documented by challenge but don’t have celiac disease, while 3% have nothing.”

Gluten is a group of proteins contained in wheat, barley, and rye that is insoluble in water. Dr. Zone described celiac disease as a “spectrum of disease” characterized by inflammation of the small intestinal mucosa that occurs with the ingestion of gluten. The condition improves when gluten is removed from the diet. From a genetic standpoint, having a predisposition to express human leukocyte antigen-DQ2 or HLA-DQ8 is required for a diagnosis of celiac disease (CD). An estimated 20%-25% of whites “have that HLA background, but it is rare in Asians,” he said. “The receptors coded by HLA genes are essential for the processing of the gliadin antigen in CD.”

The hallmark for CD is a blood test for immunoglobulin A (IgA) anti-tissue transglutaminase antibodies, which are detectable in patients with untreated disease. “You should be able to get that test for $50 or $60 in any laboratory in the country,” Dr. Zone said. “It’s about 98% reliable. You also want to do a total serum IgA to rule out IgA-deficiency.”

CD clusters with other autoimmune disorders such as Addison’s disease, autoimmune thyroiditis, atrophic gastritis, systemic lupus erythematosus, rheumatoid arthritis, myasthenia gravis, and vitiligo. It’s also common in Down syndrome. “Many patients with histological inflammation have atypical intestinal symptoms or none at all,” he said. “Clinical studies have shown that only 15%-20% of CD patients identified by serology and confirmed by biopsy have classical symptoms of diarrhea and malabsorption.” The presenting symptom in patients with celiac disease may be limited to only aphthous stomatitis, eczema, alopecia areata, psoriasis, or diabetes, along with fatigue or anemia.

Researchers who analyzed the prevalence of CD in the United States estimated the risk to be 1:133 among individuals deemed not to be at risk, 1:56 in symptomatic patients, 1:39 in second-degree relatives, and 1:22 in first-degree relatives (Arch Intern Med. 2003;163[3]:286-92.). “We tested 2,100 people in Utah and found the prevalence among first-degree relatives was 1:12,” Dr. Zone said. “The point is that CD is common, not rare. It’s as common as psoriasis. It profoundly affects the immune system, which is the modulator of inflammatory skin disease.”

Dr. Zone reported having no financial disclosures.

It’s also common in Down syndrome. “Many patients with histological inflammation have atypical intestinal symptoms or none at all,” he said. “Clinical studies have shown that only 15%-20% of CD patients identified by serology and confirmed by biopsy have classical symptoms of diarrhea and malabsorption.” The presenting symptom in patients with celiac disease may be limited to only aphthous stomatitis, eczema, alopecia areata, psoriasis, or diabetes, along with fatigue or anemia.

Researchers who analyzed the prevalence of CD in the United States estimated the risk to be 1:133 among individuals deemed not to be at risk, 1:56 in symptomatic patients, 1:39 in second-degree relatives, and 1:22 in first-degree relatives (Arch Intern Med. 2003;163[3]:286-92.). “We tested 2,100 people in Utah and found the prevalence among first-degree relatives was 1:12,” Dr. Zone said. “The point is that CD is common, not rare. It’s as common as psoriasis. It profoundly affects the immune system, which is the modulator of inflammatory skin disease.”

Dr. Zone reported having no financial disclosures.

PARK CITY, UTAH – Since most people with psoriatic arthritis (PsA) develop psoriasis before joint symptoms, it’s helpful to have a simple screening test for the condition.

One of Dr. Philip Mease’s favorite PsA screening tools is the Psoriasis Epidemiology Screening Test (PEST), which was first described at the 2009 annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) and consists of five simple questions. They are: Have you ever had a swollen joint (or joints)? Has a doctor ever told you that you have arthritis? Do your fingernails or toes have holes or pits? Have you had pain in your heel? Have you had a finger or toe that was completely swollen and painful for no apparent reason? (Clin Exp Rheumatol. 2009;27:469-74).

“Just these five simple questions, or trying to remember a few of them, can help you in your review of systems,” Dr. Mease, director of arthritis research at Swedish Medical Center, Seattle, said at the annual meeting of the Pacific Dermatologic Association. “I think patients appreciate it when you look beyond the skin in your questioning. These can pick up [PsA] with a high sensitivity and specificity” of 0.92 and 0.78, respectively.

He went on to discuss current PsA treatment approaches. According to an evidence review that he and his associates in GRAPPA published in 2009, biologics (anti–tumor necrosis factor inhibitors) as a group were found to be effective in all five domains of the disease: peripheral arthritis, skin and nail disease, axial disease, dactylitis, and enthesitis, while the oral disease-modifying antirheumatic drugs (DMARDs) were effective for peripheral arthritis and skin and nail disease.

Other treatments that were found effective are: psoralen and UVA/UVB for skin and nail disease, physiotherapy for axial disease, intra-articular steroids for peripheral arthritis, and NSAIDs for peripheral arthritis and axial disease (J Rheum. 2009;33:1417-21). “Patients with mild disease can be tried on NSAIDs, especially in a patient with monoarticular disease, but for the most part we need to move on to using systemic medication,” he said. Updated recommendations from GRAPPA include new data regarding ustekinumab, apremilast, and secukinumab, as well as data on comorbidities (J Rheumatol. 2015;42[6]:1052-5).

According to Dr. Mease, controlled trials of DMARDs in PsA patients have yielded treatment effects that range from marginal in the joints to marginal or none at all in the skin. Data from the Methotrexate in Psoriatic Arthritis trial conducted in the United Kingdom and published in 2012 showed no evidence that methotrexate improves inflammatory synovitis in active PsA (Rheumatol. 2012;51:1368-77).

“There were issues with this trial, including the fact that it took 5 years to enroll patients, and many dropped out, so I don’t think it’s a very reliable study,” said Dr. Mease, who is also a professor of medicine in the division of rheumatology at the University of Washington, Seattle. “Currently, Amgen is in the process of starting a trial in which the goal is to enroll 840 subjects with early PsA who are being randomized to methotrexate alone, Enbrel alone, or Enbrel plus methotrexate. This, I think, is going to give us a better answer about the effectiveness of methotrexate. It will also teach us about whether there’s a value in combining an anti-TNF inhibitor with methotrexate. We still don’t know the answer to that question.”

The most recent data on methotrexate come from an open-label trial known as TICOPA, which used a tight control treatment paradigm through 48 weeks of treatment. A subanalysis of 188 patients treated with methotrexate through 12 weeks was presented at the 2015 meeting of the European League Against Rheumatism. It revealed that 41% of patients achieved an ACR 20, 22% achieved minimal disease activity, 62% experienced an improvement in dactylitis, and 25% experienced an improvement in enthesitis.

“So we have a few data suggesting that methotrexate may be modestly effective in treating PsA,” Dr. Mease said. “We often will start with methotrexate unless the patient has really aggressive disease activity. If they get some effect from the drug but not enough, we’ll often add a biologic agent but often keep some methotrexate in the background, even at 10 mg per week, in order to reduce immunogenicity from a biologic.”

Dr. Mease disclosed that he has received research grants, consultation fees, and/or speaker honoraria from AbbVie, Amgen, Bristol-Myers Squibb, Celgene, Crescendo Bioscience, Genentech, GlaxoSmithKline, Janssen, Eli Lilly, Merck, Novartis, Pfizer, and UCB.
