Key clinical point: Uveitis related to psoriatic arthritis (PsA) had a prevalence of approximately 5%, presented as an acute and recurrent disease with anterior and unilateral involvement, and was associated with impaired quality of life and increased functional disability.

Major finding: Uveitis onset was acute in all cases, with 50% being recurrent and 80% being anterior and unilateral. Patients with vs without uveitis had a higher PsA impact of Disease Score (P  =  .001) and Bath Ankylosing Spondylitis Functional Index (P  =  .01) and a higher prevalence of HLA-B27 (P < .0001), sacroiliitis on magnetic resonance imaging (P  =  .027), and ocular surface pathology (P  =  .021).

Study details: This retrospective longitudinal study included 406 patients with PsA, of which 4.9% of patients experienced ≥1 episode of uveitis.

Disclosures: This study did not receive any specific funding. Several authors declared receiving grants, research support, consulting fees, or honoraria for participation in company-sponsored speaker's bureaus from various sources.

Key clinical point: Targeted musculoskeletal ultrasound performed by trained dermatologists improved the accuracy of early psoriatic arthritis (PsA) diagnosis and may eventually decrease referral to rheumatologists.

Major finding: Use of musculoskeletal ultrasound changed the sensitivity and specificity of early PsA screening strategy from 88.2% (95% CI 58.1%-94.6%) and 54.4% (95% CI 44.8%-64.1%) to 70.6% (95% CI 38.4%-81.9%) and 90.4% (95% CI 83.9%-95.6%), respectively. Overall, 45 of the 46 patients were cleared of preliminary diagnosis-based PsA suspicion after musculoskeletal ultrasound.

Study details: This was a prospective study including 140 patients with psoriasis who presented to dermatologists with arthralgia, of which 19 patients were diagnosed with PsA by a rheumatologist.

Disclosures: This study was supported by Novartis Pharma. The authors declared no conflicts of interest.

People of color with epilepsy, including Black, Hispanic, and Native Hawaiian and other Pacific Islander patients, are significantly less likely to be prescribed the latest antiseizure medications (ASMs), compared with their White counterparts, new research shows.

Even after controlling for epilepsy severity, comorbid conditions, and other factors that might affect medication choice, researchers found that newer medication use was 29% less likely in Black patients, 23% less likely in Native Hawaiian and other Pacific Islander patients, and 7% less likely in Hispanic patients, compared with White individuals.

“I hope that clinicians will see from our findings that minoritized patients with epilepsy face a myriad of barriers in receiving the highest quality of care, including ASM use,” said lead investigator Wyatt P. Bensken, PhD, adjunct assistant professor of Population and Quantitative Health Sciences at Case Western Reserve University, Cleveland. “Considering your patients’ barriers, and how that influences their care – including ASM selection – will be critical to helping reduce these population-level inequities.”

A prompt for practice change

For the study, researchers used Medicaid claims for more than 78,000 people who had filled at least two prescriptions for an ASM between 2010 and 2014.

Most patients were White (53.4%); 22.6% were Black; 11.9% were Hispanic; 1.6% were Asian; 1.5% were Native Hawaiian or other Pacific Islander; 0.6% American Indian or Alaskan Native; and 8.3% were classified as “other.”

One-quarter of participants were taking an older ASM, such as carbamazepine, phenytoin, and valproate. About 65% were taking second-generation ASMs, including gabapentin, levetiracetam, and zonisamide. A little less than 10% were taking lacosamide, perampenel, or another third-generation ASM.

Compared with White patients, newer medication prescriptions were significantly less likely in Black individuals (adjusted odds ratio, 0.71; 95% confidence interval, 0.68-0.75), Native Hawaiian or other Pacific Islanders (aOR, 0.77; 95% CI, 0.67-0.88), and Hispanic patients (aOR, 0.93; 95% CI, 0.88-0.99).

Third-generation ASMs were used by 10.7% of White patients versus 6% of Black individuals and 5.1% of American Indian or Alaskan Native patients.

Researchers also found that taking a second-generation ASM was associated with better treatment adherence (aOR, 1.17; 95% CI, 1.11-1.23) and that patients on newer ASMs were more than three times as likely to be under the care of a neurologist (aOR, 3.26; 95% CI, 3.13-3.41).

The findings draw attention to racial inequities surrounding access to medication and specialists and subspecialists, Dr. Bensken said. Identifying specific barriers and developing solutions is the long-range goal, he added.

“In the interim, increasing the attention to these inequities will, we hope, prompt changes across practices,” Dr. Bensken said.
 

A ‘wake-up call’

Commenting on the findings, Joseph Sirven, MD, professor of neurology at the Mayo Clinic Florida, Jacksonville, said the results were “striking” because newer ASMs are generally the go-to for most physicians who treat epilepsy. 

“Use of first-generation ASMs is typically reserved [for] if one runs out of options,” Dr. Sirven said.

This study and others like it should serve as a “wake-up call” for clinicians, Dr. Sirven added.

“This study is important because it shows that whether we realize it or not, race and ethnicities are playing a role in ASM, and this is related to financial access to newer-generation drugs,” he said. “Similar findings are seen in impoverished countries where first-generation ASM drugs are routinely used because of drug pricing.”
 

More to explore

Also commenting on the study, Scott Mintzer, MD, a professor and director of the Epilepsy Monitoring Unit at Thomas Jefferson University, Philadelphia, said using first-generation ASMs as a proxy for quality of care is “a very innovative concept.”

“From that perspective, the finding that racial minority patients are more likely to be on a first-generation drug is not surprising. But after that it gets far more complicated to interpret,” he added.  

Neither adherence nor care by a neurologist was different in a consistent direction within the various minority populations, Dr. Mintzer noted. In addition, Black patients were as likely to see a neurologist as White patients but still more likely to be on a first-generation drug.

There are also a few caveats to the findings that should be considered, Dr. Mintzer added. First, the sample included only Medicaid recipients, nearly 35% of whom had a comorbid psychosis. Those and other characteristics of the study pool suggest participants aren’t representative of the United States population as a whole. Second, significant shifts in ASM use have occurred since the study data cutoff in 2014, none of which are reflected in these findings.

“So, I don’t think we can really say how to address this yet,” Dr. Mintzer said. “There’s a lot to explore about whether this is still occurring, how generalizable these findings are, and what they might be due to, as there are a host of potential explanations, which the authors themselves acknowledge.”

The study was funded by the U.S. Centers for Disease Control and Prevention and the National Institute on Minority Health and Health Disparities. Dr. Bensken has received support for this work from NIMHD and serves on the Editorial Board of the journal Neurology. Dr. Sirven and Mintzer report no relevant financial relationships.

Key clinical point: Ustekinumab and tumor necrosis factor inhibitors (TNFi) demonstrated similar efficacy and persistence and were well tolerated as first-line to third-line biologic treatment for psoriatic arthritis (PsA).

Major finding: Over 3 years, treatment with ustekinumab vs TNFi resulted in comparable odds of attaining clinical Disease Activity Index for PsA low disease activity (adjusted odds ratio [aOR] 0.89; 95% CI 0.63-1.26) and remission (aOR 0.72; 95% CI 0.50-1.05), similar risk for stopping/switching treatment (adjusted hazard ratio 0.87; 95% CI 0.68-1.11), and no clinically relevant difference in serious adverse event rates (6.3% vs 7.2%).

Study details: The data come from an analysis of 895 patients with PsA from PsABio, a prospective observational study, who were prescribed first-line to third-line ustekinumab or a TNFi.

Disclosures: This study was sponsored by Janssen. Two authors declared being current or former employees of or owning stocks in Johnson & Johnson or Janssen. Several authors reported receiving personal fees, consulting fees, grants, payments, or honoraria from Janssen and various other sources.

Key clinical point: Fluorescence-optical imaging (FOI) successfully detected the early signs of musculoskeletal inflammation in hands and predicted transition from psoriasis to psoriatic arthritis (PsA) at initial stages in patients with psoriasis at risk for PsA.

Major finding: PsA diagnosis was confirmed by clinical evaluations (CE) in 50% of patients with psoriasis at risk for PsA and an additional 30% of patients who were positive on FOI. Compared with previously published annual incidence rates, the incidence rate of PsA was higher among patients positive on FOI but negative on CE (11.8%).

Study details: This was an investigator-initiated prospective two-part observational cohort study including 389 patients with plaque psoriasis who were at risk for PsA.

Disclosures: This study was sponsored by Fraunhofer ITMP and supported by a research grant from Pfizer Germany. Five authors declared being supported by Fraunhofer ITMP.

Key clinical point: Patient-reported flares occurred more frequently than physician-reported flares and demonstrated moderate agreement with worsening of disease activity in psoriatic arthritis (DAPSA), with patients with psoriatic arthritis (PsA) who reported flares having a significantly more active disease.

Major finding: Overall, 27.0% and 17.6% of patients had patient-reported and physician-reported flares, respectively, with patient-reported flare demonstrating 69.8% crude agreement with DAPSA (prevalence adjusted bias adjusted kappa  =  0.40) and patients reporting vs not reporting disease flare indicating a significantly more active disease for all outcomes (P < .001) except skin lesions (P  =  .01).

Study details: This was a longitudinal observational study including 222 patients with PsA.

Disclosures: This study was supported by unrestricted investigator-initiated research grant from Pfizer. Three authors declared receiving funds, research grants, or support from the US National Institutes of Health and other sources.

Key clinical point: Ultrasound-detected residual inflammation in peripheral articular structures may be present even in patients with psoriatic arthritis (PsA) who have achieved stable minimal disease activity (MDA), with residual inflammation being more prevalent in patients with shorter duration of MDA.

Major finding: Despite stable MDA, 54.2% of patients had ≥1 positive Power Doppler (PD) signal in examined tissues, with 19.4% and 23.6% of patients showing ≥1 joint and enthesis with a positive PD signal, respectively. A higher proportion of patients with ≤12 vs >12 months of sustained MDA had ≥1 ultrasound detected PD lesion (55% vs 41%; P  =  .024).

Study details: This cross-sectional study included 72 patients with PsA who were on biologic or conventional synthetic disease-modifying antirheumatic drugs for ≥12 months and in continuous MDA for ≥6 months.

Disclosures: This study did not declare the source of funding. The authors declared no conflicts of interest.

Key clinical point: The overall incidence of hematologic malignancies was not higher among patients with psoriatic arthritis (PsA) receiving treatment with tumor necrosis factor inhibitors (TNFi) compared with those who were biological disease-modifying antirheumatic drug (bDMARD) naive or individuals from the general population.

Major finding: Overall, the incidence rate of hematologic malignancies was similar among patients treated with TNFi vs those who were bDMARD naive (incidence rate ratio [IRR] 0.96; 95% CI 0.68-1.35) or individuals in the general population (IRR 1.35; 95% CI 0.98-1.86).

Study details: Findings are from a cohort study including patients with PsA who either initiated first TNFi (n = 10,621) or were bDMARD-naive (n = 18,387) and matched comparators from the general population.

Key clinical point: The failure to achieve minimal disease activity (MDA) in the first year after the diagnosis of psoriatic arthritis (PsA) was associated with worse health-related quality of life and health status, functional impairment, fatigue, pain, and higher anxiety and depression.

Major finding: Compared with patients who achieved sustained MDA in the first year after diagnosis, those who did not achieve MDA had higher scores for pain (estimated mean difference [β] 35.38), fatigue (β 17.88), and functional ability (β 0.81; all P < .001) and higher anxiety and depression (both P < .001) during follow-up, which persisted despite treatment intensification.

Study details: This prospective cohort study included 240 patients with newly diagnosed PsA with oligoarthritis or polyarthritis  who were disease-modifying antirheumatic drug naive.

Disclosures: This study was sponsored by UCB Pharma. S Welby and AR Prickett declared being stockholders of UCB.

Key clinical point: The addition of methotrexate or maintenance of ongoing methotrexate did not significantly enhance the efficacy of ustekinumab in patients with active psoriatic arthritis (PsA), suggesting ustekinumab as an effective therapy for PsA independent of methotrexate.

Major finding: Ustekinumab monotherapy demonstrated non-inferiority over ustekinumab+methotrexate with a comparable Disease Activity Score in 28 joints (DAS28) at week 24 (mean 2.9 vs 3.1; Mann-Whitney estimator 0.5426) and at week 52 (mean 2.8 vs 3.1; Mann-Whitney estimator 0.5461). Overall, serious adverse events occurred in 9% of patients in both treatment groups, but no deaths were reported.

Study details: Findings are from MUST, a phase 3b trial including 173 ustekinumab-naive patients with active PsA who were randomly assigned to receive ustekinumab+methotrexate or ustekinumab+placebo.
