Psoriasis

Receiving treatment with a biologic medication, compared with no biologic treatment, appeared to be associated with a lower risk for developing psoriatic arthritis (PsA) in patients with psoriasis.

That’s according to the results of a nested case-control study involving electronic medical record data from an Israeli health maintenance organization in Arthritis & Rheumatology. Compared with no biologic treatment, the risk for developing PsA among PsO patients was reduced by 39%.

This study shows “a statistically and clinically significant lower risk for developing PsA among patients receiving biologic medications for psoriasis treatment,” wrote Yael Shalev Rosenthal, MPH, of the Sackler Faculty of Medicine, Tel Aviv University and colleagues. “The results suggest considering treatment with biologic medications in patients [who] present with significant risk factors for PsA at an earlier stage of treatment.”

“It would be nice to believe this story, but I don’t think we can based on the evidence we’ve got so far,” commented Philip Helliwell, PhD, DM, in an interview.

Dr. Helliwell, who is professor of clinical rheumatology at the University of Leeds (England) and an Honorary Consultant Rheumatologist for the Leeds Teaching Hospitals and Bradford Teaching Hospitals NHS Trust, noted that there were several issues with the current evidence.

Aside from their often retrospective or nonrandomized nature, prior analyses, including the current one, were based on EMR data.

“There’s actually no face-to-face patient contact going on here. It’s all done on coding, and coding can be unreliable,” Dr. Helliwell said.

While the study’s findings are “in line with other studies that have looked at this, and suggest that if you get a biologic, you’re less likely to get PsA with your psoriasis, there could be lots of reasons why.”

The big problem here is confounding by indication. “You don’t get on a biologic unless you’ve got bad psoriasis,” Dr. Helliwell explained. The Israeli criteria for starting a biologic are much higher than in the United Kingdom, he added, requiring more than 50% of patients’ body surface area to be affected, or a Psoriasis Area and Severity Index score of more than 50. Moreover, people with bad psoriasis are more likely to get PsA. This, however, makes the results more impressive.

Confounding by indication is an issue with this study, agreed consultant rheumatologist Adewale Adebajo, PhD, in a separate interview. He acknowledged, however, that the study’s authors did try to account for this by limiting the timescale of their analysis to the first 10 years of biologic therapy. They also used the usual methods of propensity score matching and multivariate Cox regression analysis to hopefully iron out any differences between the two groups of patients.

Study details and results

Ms. Rosenthal and coauthors analyzed EMR data on patients with psoriasis but not PsA that were logged in the Maccabi Healthcare Services (MHS) database. The MHS is the second-largest health maintenance organization in Israel, insuring over 2 million members, the researchers said.

In all, 663 patients with psoriasis but not PsA before or at initiation of biologic treatment were included in their analysis and matched to a control group of 663 patients with psoriasis who had not received biologic treatment. Propensity score matching was used to iron out some differences in baseline characteristics that had been seen between the groups, such as older age at diagnosis, higher body mass index, and a longer time between diagnosis and treatment seen in patients treated without biologics.

After adjusting for multiple risk factors and confounders, “the control group still had a significantly higher risk for PsA, compared to the biological treatment group,” the researchers wrote. Indeed, the adjusted hazard ratio was 1.39, with a 95% confidence interval between 1.03 and 1.87.

An ‘intriguing study’

“This is a retrospective study, and it has all the faults of a retrospective study,” said Dr. Adebajo, associate medical director for research and development at Barnsley (England) NHS Foundation Trust. But “these were patients who hopefully hadn’t yet developed psoriatic arthritis, although it is difficult to exclude subclinical psoriatic arthritis.”

The ideal would of course be to look at patients prospectively, but a randomized clinical trial would be unlikely to ever be conducted, Dr. Helliwell noted. “It would be unfair to randomize people who have got bad psoriasis and need a biologic to placebo just to prove the point really,” he said. “Getting control groups in this arena is very difficult.”

That doesn’t mean that prospective evaluation is not possible. Dr. Adebajo noted that there were already cohorts of newly diagnosed patients who were being prospectively followed up and those could perhaps be used to look at the question again in the future.

“You’re then looking at the natural history, the natural outcome, and you don’t need to worry about confounding because you’re just collecting all of the information as you go along.”

The idea that biologics might slow or even prevent the onset of PsA is “an interesting and enchanting hypothesis,” Dr. Adebajo said. “The study doesn’t prove the hypothesis, but it’s an intriguing study because it doesn’t disprove the hypothesis either.

“It gives us food for thought and a basis for further studies,” as well as some “encouragement to perhaps use biologics earlier because there may be additional benefits of doing so.”

That’s still to be proven of course, as it has been reported that patients with psoriasis can develop PsA while taking biologics.

“Clinically, that’s what we see in the combined clinic. We get people referred with psoriasis [who are] already on a biologic who developed musculoskeletal problems,” Dr. Helliwell said.

“It would be nice to believe” that biologics prevent or slow PsA in patients with psoriasis, Dr. Helliwell added, but I’m not sure these data are conclusive. From this study we know nothing about the phenotype of psoriasis, which is important in the development of PsA. In addition, we know that of the 30% of people with psoriasis who develop PsA, about half of these are undiagnosed at the time of such studies. In that case, what the biologic is doing is just treating preexisting PsA. If you count those numbers up, some of the differences between the two groups seen in this study are accounted for. From registry data there is no way of checking this.”

No external funding was used for the study. One author acknowledged acting as an investigator, adviser, or consultant to several pharmaceutical companies including AbbVie, Boehringer Ingelheim, Bristol-Myers Squibb, Coherus, Dexcel Pharma, Eli Lilly, Janssen, Novartis, and Pfizer. All other authors had nothing to disclose.

Key clinical point: Although rates of principal psoriasis hospitalizations have decreased among patients with psoriasis in the last 2 decades in the United States, hospitalization for non-psoriatic reasons has increased, which may be attributed to increased comorbidity burden driving admissions because of comorbidities.

Major finding: Between 1998 and 2018, the incidence of hospitalizations with either principal or secondary diagnosis of psoriasis increased from 17.9 to 52.0 per 100,000 persons, the proportion of patients with psoriasis hospitalized with psoriasis as principal diagnosis reduced from 4.1% to 1.0%, and those with Charlson Comorbidity Index score of 3 or higher increased from 13.9% to 30.9% (all adjusted P-trend < .0001).

Study details: This was a 21-year longitudinal trend analysis of the National Inpatient Sample database between 1998 and 2018 including adults with a principal or secondary diagnosis of psoriasis.

Disclosures: The study did not receive any funding. The authors declared no conflict of interests.

Key clinical point: A significant relation was observed between low hemoglobin levels and increased risk for psoriasis in patients with chronic kidney disease (CKD), indicating that proactive treatment for inflammation might help manage both anemia and psoriasis in patients with CKD.

Major finding: During a mean follow-up period of 6.16±1.02 years, 2.39% of patients with CKD developed psoriasis with cumulative incidence higher in patients with vs without anemia (P less than .0001). The risk for psoriasis was significantly higher in patients with vs without anemia (adjusted hazard ratio, 1.109; P < .0001).

Study details: Findings are from a retrospective cohort study of 576,461 patients with CKD.

Key clinical point: Long-term proactive management (PM) of psoriasis with calcipotriene 0.005%/betamethasone dipropionate 0.064% (Cal/BD) vs reactive management (RM) benefitted all patients irrespective of baseline characteristics, with greater benefits observed in patients with more severe disease.

Major finding: Effect of treatment on time to first relapse was consistent across all baseline parameters, with treatment group (PM vs RM; hazard ratio [HR], 0.56; P less than .001), baseline Physician Global Assessment (severe vs mild; HR, 2.32; P = .003), and modified Psoriasis Area Severity Index (severe vs mild; HR, 1.77; P = .002) having a significant impact.

Study details: This was a post hoc analysis of phase 3 PSO LONG trial which included a 52-week maintenance phase where patients with psoriasis were randomly assigned to Cal/BD twice weekly (PM) or vehicle foam (RM).

Key clinical point: Dimethyl fumarate may be considered a first-line systemic treatment option to manage psoriasis in the elderly. However, long-term safety, particularly lymphocytopenia, should be closely monitored.

Major finding: The Psoriasis Area and Severity Index score ranged from 3.7 to -24.0 (mean, 9.8±4.1) at week 0, which changed to 4.3±3.2 at week 16 and 2.7±3.2 at week 24 after dimethyl fumarate administration. Overall, 72.8% of adverse events were reported, with the most common being gastrointestinal complaints (29.6%), flushes (12.3%), and lymphocytopenia (12.35%).

Study details: Findings are from a retrospective study including 81 elderly patients with moderate-to-severe psoriasis, aged 65 years and older, treated with dimethyl fumarate for up to 24 weeks.

Major finding: The proportion of patients with itch and itch-related sleep loss reduced from 89.3% at baseline to 43.5% at week 4, and 93.4% of patients reported a 30% or more reduction in itch severity. The mean change in Dermatology Life Quality Index score at week 4 was −5.9±4.7, with 76.3% of patients achieving a score of 5 or lesser indicating no/small effect on QoL.

Study details: Findings are from CELSUS, a noninterventional prospective study including 400 patients with plaque psoriasis treated with Cal/BD aerosol foam.

Disclosures: This study was supported by LEO Pharma. Dr. Rigopoulos, Dr. Lazaridou, Dr. Georgiou, Dr. Chasapi, and Dr. Ioannides reported receiving personal fees from various sources including LEO Pharma, outside the submitted work.

Key clinical point: Prevalence of subclinical atherosclerosis is higher among patients with psoriasis and nonalcoholic fatty liver disease (NAFLD). Additionally, those with elevated hepatic inflammation had a higher burden of coronary atherosclerosis.

Major finding: Among patients with psoriasis, the prevalence of subclinical atherosclerosis was higher among those with vs without NAFLD (61% vs 23%; P = .006). Uptake of 2-[fluorine-18]fluoro-2-deoxy-D-glucose was significantly associated with noncalcified (β, 0.28; P < .001), fibrofatty (β, 0.49; P less than 001), and lipid-rich necrotic core (β, 0.28; P = .003) coronary burden.

Study details: Findings are from a 2-cohort cross-sectional study including 314 patients with psoriasis. The European cohort consisted of 76 patients with psoriasis and 76 control patients and the United States cohort consisted of 162 patients with psoriasis.

Key clinical point: Compared with the general population, patients with moderate-to-severe plaque psoriasis were at an increased risk for lympho-hematological malignancies (LHM) and lymphoma, particularly cutaneous T-cell lymphoma (CTCL).

Major finding: Patients with moderate-to-severe plaque psoriasis vs general population had significantly higher risk for LHM (hazard ratio [HR], 1.55; 95% confidence interval [CI], 1.24-2.94) and lymphoma (HR, 1.27; 95% CI, 1.08-1.50). The risk for CTCL was markedly augmented in patients with psoriasis (HR, 6.22; 95% CI, 3.39-11.42).

Study details: Findings are from a meta-analysis of 25 observational studies including 2,501,652 study subjects. Most of the studies included patients with moderate-to-severe psoriasis.

Key clinical point: Use of analgesics was higher in patients with psoriasis, particularly those with concomitant psoriatic arthritis (PsA), which could be because of increased joint pain.

Major finding: Moderate-to-severe joint pain was reported by 69% vs 45% of patients with vs without PsA (P less than .0001). Patients with psoriasis vs reference individuals used more nonsteroidal anti‐inflammatory drugs (NSAIDS; 21.0% vs 17.3%) and opioids (14.2% vs 9.0%) within 1 year. Use of NSAIDS (30.8%) and opioids (22.7%) was even higher in patients with psoriasis and PsA. Of all symptoms, only joint pain seemed to be associated with the use of analgesics (P less than .05).

Study details: Findings are from a cross-sectional study of 4,016 adults with psoriasis including 847 with concomitant PsA and 3,490 reference individuals.

Key clinical point: Patients with moderate-to-severe psoriasis who were new users of infliximab and adalimumab vs etanercept had a higher risk for serious infections. The risk was lower with ustekinumab and comparable with secukinumab, ixekizumab, brodalumab, guselkumab, or apremilast vs etanercept.

Major finding: Compared with etanercept, the risk for serious infections was higher for patients who initiated adalimumab (estimated weighted hazard ratio [wHR], 1.22; 95% confidence interval [CI], 1.07-1.38) or infliximab (wHR, 1.79; 95% CI, 1.49-2.16), whereas the risk was lower with ustekinumab (wHR, 0.79; 95% CI, 0.67-0.94). The risk for serious infections was not higher for new users of secukinumab, ixekizumab, brodalumab, guselkumab, or apremilast vs etanercept.

Study details: Findings are from the analysis of a real-world cohort of 44,239 adults with psoriasis who were new users of biologic/biosimilar or targeted synthetic antipsoriatic agents and had no history of serious infection.

Disclosures: The authors did not report any source of funding. No conflict of interests was reported.
