Psoriasis

One out of eight patients with psoriasis had a positive screen for possibly undiagnosed psoriatic arthritis, according to an analysis of data from a prospective registry.

The finding highlights the need for better psoriatic arthritis screening among patients with psoriasis, said Philip J. Mease, MD, of the University of Washington, Seattle, and associates. The simple, five-question Psoriasis Epidemiology Screening Tool (PEST) used in this study could be deployed in general or dermatology practices to identify psoriasis patients who might need a rheumatology referral, they wrote. The report is in the Journal of the European Academy of Dermatology and Venereology.

Up to 30% of patients with psoriasis have comorbid psoriatic arthritis, but many such cases go undiagnosed, and even a 6-month diagnostic delay can worsen peripheral joint erosion and physical disability.

This study included 1,516 patients with psoriasis seen at 114 private and academic practices in 34 states that participate in the independent, prospective Corrona Psoriasis Registry. A total of 904 patients without dermatologist-reported psoriatic arthritis responded to the validated PEST, which assesses risk of psoriatic arthritis by asking whether the test taker has been told by a doctor that he or she has arthritis and whether they have experienced swollen joints, heel pain, pronounced and unexplained swelling of a finger or toe, and pitting of the fingernails or toenails. Each “yes” response is worth 1 point, and total scores of 3 or higher indicate risk of psoriatic arthritis. A total of 112 (12.4%) had a score of 3 or higher.


The average age of patients who met this threshold was 53 years, 4 years older than those who did not (P = .02). Patients with PEST scores of 3 or more also had a significantly longer duration of psoriasis and were significantly more likely to have nail disease and a family history of psoriasis. Demographically, they were more likely to be white, female, and unemployed. They had significantly higher rates of several comorbidities, including depression and anxiety, cardiovascular disease, obesity, and serious infections. Finally, they reported having significantly more pain and fatigue and significantly worse health-related quality of life.

The study did not account for possible confounding. “Further research is needed to characterize patients by individual PEST score and to assess outcomes over time,” the researchers wrote. “The use of screening tools can be beneficial in the detection of psoriatic arthritis, and comprehensive efforts to validate them in multiple clinical settings must continue, along with collection of critical feedback from patients and clinicians.”

Corrona and Novartis designed and helped conduct the study. Novartis, the chief funder, participated in data analysis and manuscript review. Dr. Mease disclosed research funding from Novartis and several other pharmaceutical companies. He also disclosed consulting and speakers bureau fees from Novartis, Corrona, and several other companies.

The Food and Drug Administration has approved Eticovo (etanercept-ykro), a biosimilar of Enbrel (etanercept), for the treatment of several different rheumatologic and dermatologic conditions.

FDA approval was based in part on the results of a phase 3 trial in which 596 patients with moderate to severe rheumatoid arthritis uncontrolled by methotrexate received either Eticovo or Enbrel. The American College of Rheumatology 20% response rate after 24 weeks was 78.1% for Eticovo and 80.3% for Enbrel; the two drugs were statistically equivalent. Both groups had statistically equivalent rates of treatment-emergent adverse events (55.2% vs. 58.2%).

According to the label, Eticovo is a tumor necrosis factor blocker approved for the treatment of rheumatoid arthritis, polyarticular juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, and plaque psoriasis in patients aged 4 years or older. The most common adverse events associated with the drug include infections and injection site reactions.

Eticovo is the second etanercept biosimilar approved by the FDA. The first FDA-approved etanercept biosimilar, etanercept-szzs (Erelzi), is currently facing a legal challenge from Amgen, the manufacturer of Enbrel.

The Food and Drug Administration has approved a topical combination of corticosteroid halobetasol propionate (0.01%) and the topical retinoid, tazarotene (0.045%), in a lotion formulation, for the treatment of plaque psoriasis in adults, the manufacturer announced on April 25.

A press release from the manufacturer, Ortho Dermatologics, summarized the results of two phase 3 studies that compared treatment with the combination product, in 418 adults with moderate to severe plaque psoriasis. At week 8, the proportion of patients who had achieved treatment success – defined as at least a two-grade improvement in Investigator Global Assessment score and a score of “clear” or “almost clear” – was 36% and 45% in the treatment groups, compared with 7% and 13% of those on vehicle, respectively (P less than .001 for both).

The release also refers to a phase 2 study of 212 patients, which found that the combination treatment was more effective in treating plaque psoriasis than was either component separately (J Drugs Dermatol. 2017 Mar 1;16[1]:197-204). By week 8, 52.5% of patients treated with the combination lotion had shown treatment success – compared with 33.3% of those treated with halobetasol, 18.6% of those treated with tazarotene, and 9.7% of those treated with vehicle (P = .033).

Common treatment-related adverse events included treatment site reactions, such as irritation, pain, itching, and folliculitis. Treatment may cause birth defects if used during pregnancy, so a negative pregnancy test should be obtained before treatment begins and effective birth control should be used during treatment.

It will be marketed under the trade name Duobrii and is priced at $825 for a 100-gram tube, according to the press release.

Risankizumab, an interleukin-23 inhibitor, has been approved by the Food and Drug Administration for treating moderate to severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy, the manufacturer announced on April 23.

Risankizumab selectively inhibits interleukin-23 (IL-23), a key inflammatory protein, by binding to its p19 subunit. The drug is administered at a dose of 150 mg, in two subcutaneous injections, every 12 weeks, after starting doses at weeks 0 and 4. It will be available in early May, according to an AbbVie press release announcing the approval.

The approval was based in part on data from two phase 3, 2-year studies, In UltIMMA-1 and UltIMMA-2, at 16 weeks, 75% of risankizumab patients in both studies achieved a Psoriasis Area and Severity Index (PASI 90), compared with 5% and 2% of those on placebo, respectively. These results were published in 2018 (Lancet. 2018 Aug 25;392[10148]:650-61).

At 1 year, 82% and 81% of those treated with risankizumab in the two studies achieved a PASI 90, and 56% and 60% achieved a PASI 100, respectively, according to the company.

Approval was also based on additional phase 3 studies, IMMhance and IMMvent.

Upper respiratory infections were among the most common adverse events associated with risankizumab in trials, reported in 13%, according to the company. Other adverse events associated with treatment included headache (3.5 %), fatigue (2.5 %), injection site reactions (1.5%) and tinea infections (1.1%). The AbbVie release states that candidates for treatment should be evaluated for tuberculosis before starting therapy, and patients should be instructed to report signs and symptoms of infection.

Risankizumab, which will be marketed as Skyrizi, was recently approved in Canada for the same indication, and in Japan, for plaque psoriasis, generalized pustular psoriasis, erythrodermic psoriasis and psoriatic arthritis in adults. It currently is under review in Europe.

AbbVie and Boehringer Ingelheim are collaborating on the development of risankizumab, according to an AbbVie press release. Studies of risankizumab for treatment of psoriatic arthritis and Crohn’s disease are underway.

High plasma levels of tumor necrosis factor (TNF)–alpha and adiponectin can be used to differentiate patients with psoriasis and psoriatic arthritis, according to Wen-Qing Li, PhD, of Brown University, Providence, R.I., and his associates.

In a research letter published in the British Journal of Dermatology, the investigators detailed an analysis of 180 patients with psoriasis only and 143 patients with psoriatic arthritis (PsA) from the Psoriatic Arthritis and Psoriasis Follow-up Study. Patients in both groups had a mean age of 51 years. Plasma levels of interleukin-6, C-reactive protein, TNF-alpha, leptin, total adiponectin, and high-molecular-weight (HMW) adiponectin were assessed as potential biomarkers by ultrasensitive enzyme-linked immunosorbent assay or immunoturbidimetric assay.

Median TNF-alpha plasma levels were higher in patients with PsA, compared with those with psoriasis (3.27 vs. 1.32 pg/mL^–1), while total and HMW adiponectin levels were lower in patients with PsA, compared with those with psoriasis (4.66 vs. 5.36 mcg/mL^–1; 2.58 vs. 3.01 mcg/mL^–1). After logistic regression, TNF-alpha (adjusted odds ratio, 2.25; 95% confidence interval, 1.41-3.61) and total adiponectin (aOR, 0.61; 95% CI, 0.39-0.96) remained significantly associated as biomarkers. HMW adiponectin maintained marginal significance (aOR, 0.64; 95% CI, 0.41-1.01).

“Further large-scale investigation in a prospective setting of patients with PsO [psoriasis] would be warranted, if a clinically useful screening test is to be developed for risk prediction of PsA based on circulating biomarkers,” the investigators concluded.

Two study authors reported consulting with or advising numerous pharmaceutical companies.

Treatment failure and the adverse effects of traditional psoriasis medications increasingly are driving patients to complementary and alternative medicines (CAMs), despite limited documentation supporting their efficacy, reported Emily C. Murphy and her associates, in the department of dermatology, George Washington University, Washington.

They performed a survey-based statistical analysis to identify specific types of commonly used CAMs, and to explore reasons patients increasingly turn to alternative therapies. The survey was distributed in the National Psoriasis Foundation’s (NPF) October 2018 newsletter to its 100,927 members. Their results were published in a letter to the editor of the Journal of the American Academy of Dermatology.

Of the 6,101 NPF members who opened the newsletter, 324 clicked on the survey link. Of the 219 who completed the survey, almost 70% were women. The majority were white (84.1%), compared with Hispanic (6.2%), Asian (3.1%), and black (2.6%) participants. Most of the survey respondents had a dermatologist diagnosis of psoriasis, as well as access to health insurance to cover any prescribed medicines needed.

Of the 41% of respondents who reported using alternative therapies, usage was especially high among those who considered their psoriasis as severe (50% vs. 33.6% of those with nonsevere disease). Among the respondents, women were more likely than were men to use CAMs (45.6% vs. 26.5%, P = .002).

Only 4% cited access to care as a reason for choosing alternative therapies; the majority said they used CAMs because “traditional medications did not help or had side effects.”

While men were more likely than were women to use vitamins (24% vs. 18.9%, respectively), Dead Sea bath salts (17% vs. 7.8%), and cupping (3% vs. 0.8%), women were more likely to use herbals/botanicals (17% vs. 14%) and yoga (9.6% vs. 2%).

Patients with moderate psoriasis were significantly more likely than were those with mild or severe cases of the disease to recommend CAMs, regardless of insurance status (52.4% vs. 35% among those with mild disease and 40.4% for those with severe disease).

For some of the commonly used treatments, such as vitamins D and B₁₂, there is insufficient evidence documenting their efficacy, although Dead Sea treatments have been shown to have therapeutic effects. And while there is efficacy evidence for indigo naturalis and meditation, these were not mentioned or were not commonly reported by respondents, the authors pointed out.

Although just 43% of patients said they would recommend a CAM to other people with psoriasis, its use remains widespread. For this reason, “educational initiatives that enable physicians to discuss evidence-based CAMs may improve patient satisfaction and outcomes,” observed Ms. Murphy, a research fellow, and her associates.

Previous studies have cited rates of CAM usage among patients with psoriasis as high as 62%, but researchers have failed to examine the reasons motivating usage. Not surprisingly, patients often use but misunderstand the benefits of alternative therapies.

“The onus is on us as physicians to not only ask our patients if they are using nonallopathic therapies for their psoriasis, but also to create an accepting environment that enables further discussion regarding said treatments to ensure patient safety and ultimately good outcomes,” senior author Adam Friedman, MD, professor and interim chair of dermatology at George Washington University, said in an interview.

The authors had no financial sources or conflicts of interest to disclose; there was no funding source.

Treatment failure and the adverse effects of traditional psoriasis medications increasingly are driving patients to complementary and alternative medicines (CAMs), despite limited documentation supporting their efficacy, reported Emily C. Murphy and her associates, in the department of dermatology, George Washington University, Washington.

They performed a survey-based statistical analysis to identify specific types of commonly used CAMs, and to explore reasons patients increasingly turn to alternative therapies. The survey was distributed in the National Psoriasis Foundation’s (NPF) October 2018 newsletter to its 100,927 members. Their results were published in a letter to the editor of the Journal of the American Academy of Dermatology.

Of the 6,101 NPF members who opened the newsletter, 324 clicked on the survey link. Of the 219 who completed the survey, almost 70% were women. The majority were white (84.1%), compared with Hispanic (6.2%), Asian (3.1%), and black (2.6%) participants. Most of the survey respondents had a dermatologist diagnosis of psoriasis, as well as access to health insurance to cover any prescribed medicines needed.

Of the 41% of respondents who reported using alternative therapies, usage was especially high among those who considered their psoriasis as severe (50% vs. 33.6% of those with nonsevere disease). Among the respondents, women were more likely than were men to use CAMs (45.6% vs. 26.5%, P = .002).

Only 4% cited access to care as a reason for choosing alternative therapies; the majority said they used CAMs because “traditional medications did not help or had side effects.”

While men were more likely than were women to use vitamins (24% vs. 18.9%, respectively), Dead Sea bath salts (17% vs. 7.8%), and cupping (3% vs. 0.8%), women were more likely to use herbals/botanicals (17% vs. 14%) and yoga (9.6% vs. 2%).

Patients with moderate psoriasis were significantly more likely than were those with mild or severe cases of the disease to recommend CAMs, regardless of insurance status (52.4% vs. 35% among those with mild disease and 40.4% for those with severe disease).

Patients with psoriasis or psoriatic arthritis who started ustekinumab (Stelara) versus a tumor necrosis factor inhibitor had no differences in the overall risks of incident atrial fibrillation (AFib) or major adverse cardiovascular events (MACE), according to authors of a retrospective cohort study of two commercial insurance databases.

Subgroup analyses in the study also revealed “no statistically significant heterogeneity” in risk of AFib or MACE by age, sex, or presence of diabetes, Moa P. Lee, PharmD, of Brigham and Women’s Hospital and Harvard Medical School, Boston, and her coauthors reported in JAMA Dermatology.

These findings provide additional evidence on cardiovascular risks with ustekinumab versus other treatments.

The findings are consistent with previous observations of a small but nonsignificant increase in cardiovascular disease among patients with psoriatic disease and provide new insight into the risk of AFib with psoriatic treatments with the two therapies, Dr. Lee and her colleagues wrote.

The retrospective study of two U.S. commercial health care claims databases included 60,028 adult patients with psoriasis or psoriatic arthritis who initiated therapy with ustekinumab (n = 9,071) or a tumor necrosis factor (TNF) inhibitor (n = 50,957), including adalimumab, certolizumab pegol, golimumab, etanercept, or infliximab. The investigators excluded any patient with an AFib diagnosis at baseline and those receiving any antiarrhythmic or anticoagulant treatment.

The incidence of AFib was 5.0 and 4.1 per 1,000 person-years in the ustekinumab and TNF inhibitor groups, respectively, with an adjusted hazard ratio of 1.08 (95% CI, 0.76-1.54). The incidence of MACE (a composite endpoint of MI, stroke, and coronary revascularization) was 6.2 and 6.1 per 1,000 person-years in the ustekinumab and TNF inhibitor groups, with an adjusted hazard ratio of 1.10 (95% CI, 0.80-1.52).

In subgroup analyses, the adjusted HR for AFib with ustekinumab versus TNF inhibitor was 1.46 (95% CI, 0.98-2.18) for patients aged 60 years and older and 1.47 (95% CI, 0.93-2.31) in patients with diabetes, the investigators wrote.

The adjusted HR for AFib with ustekinumab versus TNF inhibitors was 1.21 in men (95% CI, 0.87-1.69) and 0.82 in women (95% CI, 0.49-1.39), while for MACE, the HRs were 1.31 in men (95% CI, 0.97-1.76) and 0.91 in women (95% CI, 0.56-1.47).

“Although the risk of these cardiovascular outcomes appeared to be similar across the subpopulations included in our study, further investigations on potentially modifying treatment effects stratified by important risk factors may be warranted,” Dr. Lee and her coauthors wrote.

The study was supported by the division of pharmacoepidemiology and pharmacoeconomics at Brigham and Women’s Hospital. Several authors reported financial relationships with pharmaceutical companies marketing biologics for psoriasis and psoriatic arthritis.

There is no apparent association between proinflammatory foods and increased risk of incident psoriasis, psoriatic arthritis, or atopic dermatitis, reported Alanna C. Bridgman of Queen’s University, Kingston, Ont., and her associates.

In a large, retrospective cohort study among women from the Nurses’ Health Study II (NHS-II), including 85,185 psoriasis participants and 63,443 atopic dermatitis participants, Ms. Bridgman and her associates sought to determine whether proinflammatory diet increased the risk of incident psoriasis, psoriatic arthritis, or atopic dermatitis. Clinicians administered food frequency questionnaires every 4 years beginning in 1991 among female nurses aged 25-42 years.

Food groups included in the evaluation were those most predictive of three plasma markers of inflammation: interleukin-6 (IL-6), C-reactive protein (CRP), and tumor necrosis factor–alpha R2 (TNF-R2). Proinflammatory foods included processed meat, red meat, organ meat, white fish, vegetables other than leafy green and dark yellow, refined grains, low- and high-energy drinks, and tomatoes. Anti-inflammatory foods included beer, wine, tea, coffee, dark yellow and green leafy vegetables, snacks such as popcorn and crackers, fruit juice, and pizza.

No association was found between proinflammatory diet and increased likelihood for incident psoriasis, psoriatic arthritis, or atopic dermatitis. Although proinflammatory dietary patterns were associated with psoriatic arthritis in the age-adjusted model, the hazard ratio was attenuated and found to be no longer statistically significant after adjustment for important confounders such as body mass index. In addition, no significant relationship between atopic dermatitis and proinflammatory diet was observed, they reported. The study was published in the Journal of the American Academy of Dermatology.

Ms. Bridgman and her associates measured dietary patterns using the Empirical Dietary Inflammatory Pattern (EDIP); dietary patterns measuring high on the EDIP scale were associated with higher levels of TNF-alpha, TNF-alpha R1, TNF-alpha R2, CRP, IL-6, and adiponectin. Psoriasis and psoriatic arthritis are Th1- and Th17-mediated diseases that exhibit higher serum levels of IL-6, CRP, and TNF-alpha, unlike atopic dermatitis, which is primarily a Th2-mediated condition featuring reduced involvement of the Th1/Th17 inflammatory cytokines.

Because a goal of the EDIP score was to “account for the overall effect of dietary patterns,” the researchers included in their analysis only those food groups that “explain the maximal variation in the three noted inflammatory biomarkers.”

All patients included in the study were questioned at baseline regarding their height and race/ethnicity. Weight, smoking status, and physical activity, and diagnoses of hypercholesterolemia, type 2 diabetes, cardiovascular disease, and asthma were monitored biennially.

Overall, patients with higher EDIP scores were found to have higher BMI, lower physical activity, and alcohol use, as well as increased rates of hypercholesterolemia and hypertension.

“Though we found no convincing evidence for an association with EDIP score for any of the investigated diseases, the results followed an internal pattern consistent with our hypotheses that higher EDIP scores would have more of an association with psoriatic disease than with atopic dermatitis,” the researchers wrote.

Citing recent evidence gathered in studies, such as the French NutriNet-Santé study, which demonstrated proinflammatory effects similar to those measured with the EDIP in cases where there was low adherence to the Mediterranean diet, the authors attributed their contradictory findings to “important methodological differences.” Unlike the NutriNet-Santé study, which classified psoriasis by severity, Ms. Bridgman and her colleagues examined the overall risk of incident psoriasis. “It is possible that a dietary index associated with more Th-2 inflammation would yield different results,” they noted.

The large sample size, prospectively collected dietary, and psoriatic disease data, as well as the ability to adjust for important confounding factors, were included among the strengths of the study.

That the participants were limited to U.S. women could be considered a limitation because the results may not be generalizable to other populations. The results also may not be relevant to child-onset disease because the patient population included only cases of adult-onset atopic dermatitis. Questionnaire-based diagnoses increase the likelihood of misclassification, so “dilution of the case pool with false-positive cases would bias our results towards the null,” they added.

Ultimately, the authors noted that proinflammatory diet may be associated with other health risks, but these do not warrant counseling patients concerning their possible impact in cases of psoriatic disease or atopic dermatitis.

The study was funded by Brown University department of dermatology and from Regeneron, Sanofi, the National Institutes of Health, and the National Cancer Institute. Two coauthors, one of whom has a patent pending for the nix-tix tick remover, disclosed ties with various companies.

WASHINGTON – Psoriasis induced by tumor necrosis factor (TNF) therapy is among the treatment-associated effects that involve the skin in patients with inflammatory bowel disease (IBD), Sophia Delano, MD, said during a session on the cutaneous effects of IBD at the annual meeting of the American Academy of Dermatology.

This is a paradoxical reaction, which can happen “weeks to years after starting a TNF blocker,” with about 70% of cases occurring during the first year of therapy, said Dr. Delano, an attending physician in the dermatology program at Boston Children’s Hospital.

Those receiving infliximab are more likely to develop TNF inhibitor–induced psoriasis, compared with those on adalimumab or etanercept. TNF inhibitor–induced psoriasis may not track with gastrointestinal activity, and some patients whose gastrointestinal disease is responding to treatment can begin to develop psoriasis, she noted.

The clinical presentation of TNF inhibitor–induced psoriasis can also vary. In one study of 216 cases, 26.9% of patients had a mixed morphology, with the most common presentations including plaque psoriasis (44.8%) and palmoplantar pustular psoriasis (36.3%). Other presentations were psoriasiform dermatitis (19.9%), scalp involvement with alopecia (7.5%), and generalized pustular psoriasis (10.9%). Locations affected were the soles of the feet (45.8%), extremities (45.4%), palms (44.9%), scalp (36.1%), and trunk (32.4%), Dr. Delano said.


TNF inhibitor–induced psoriasis is likely a class effect, she said, noting that, in the same review, symptoms resolved in 47.7% of patients who discontinued TNF inhibitors, in 36.7% of patients who switched to another TNF inhibitor, and in 32.9% of patients who continued their original therapy (J Am Acad Dermatol. 2017 Feb;76[2]:334-41). In the study, Crohn’s disease and RA were the most common diseases, in 40.7% and 37.0% of the patients, respectively.

There have been case reports of TNF antagonist–induced lupus-like syndrome (TAILS), which is more common in patients with RA and ulcerative colitis. TAILS occurs more often in women than in men; can present similarly to systemic lupus erythematosus, subacute cutaneous lupus erythematosus, and chronic cutaneous lupus; and resolves by stopping TNF inhibitor treatment, Dr. Delano said.

Skin cancer risk, infections, and injection site reactions

Both adult and pediatric patients treated with TNF inhibitors for IBD may be at increased risk for lymphoma, visceral tumors, melanoma, and nonmelanoma skin cancers. Dr. Delano referred to a study published in 2014, which identified 972 reports of melanoma in the Food and Drug Administration’s Adverse Event Reporting System database associated with TNF inhibitor use; of these, 69 cases involved patients using more than one TNF inhibitor. Infliximab, golimumab, etanercept, and adalimumab were associated with a safety signal for melanoma, but not certolizumab (Br J Dermatol. 2014 May;170[5]:1170-2).

Dr. Delano observed that thiopurines such as azathioprine are also associated with an increased cancer risk, as noted in one retrospective study that found that the risk of nonmelanoma skin cancer was 2.1 times higher in a mostly white male cohort with ulcerative colitis during treatment with thiopurines, compared with patients not treated with thiopurines (Am J Gastroenterol. 2014 Nov;109[11]:1781-93). A greater duration of treatment (more than 6 months) and higher doses were associated with higher risks.

Adalimumab, golimumab, and certolizumab can also cause injection site reactions, typically within 1- 2 days of injection, said Dr. Delano. In these cases, symptoms of erythema, warmth, burning, or pruritus are worse at the beginning of treatment and can be relieved by rotating the injection site as well as providing cool compresses, topical steroids, antihistamines, and supportive care.

“If you have a patient with a worsening reaction, consider it may represent the type 1 IgE-related hypersensitivity requiring desensitization to continue that systemic,” she noted.

Cutaneous bacterial, fungal, and viral infections such as molluscum contagiosum, verruca vulgaris, herpes simplex, and varicella zoster can occur as a result of TNF inhibition as well, and can be difficult to clear because of immunosuppression, she added.

Dr. Delano reported no relevant conflicts of interest.

WASHINGTON – Psoriasis induced by tumor necrosis factor (TNF) therapy is among the treatment-associated effects that involve the skin in patients with inflammatory bowel disease (IBD), Sophia Delano, MD, said during a session on the cutaneous effects of IBD at the annual meeting of the American Academy of Dermatology.

This is a paradoxical reaction, which can happen “weeks to years after starting a TNF blocker,” with about 70% of cases occurring during the first year of therapy, said Dr. Delano, an attending physician in the dermatology program at Boston Children’s Hospital.

Those receiving infliximab are more likely to develop TNF inhibitor–induced psoriasis, compared with those on adalimumab or etanercept.
