SLE more prevalent in psoriatic arthritis patients: Study
Israel: Patients with psoriatic arthritis are at 2.3 times more risk of getting systemic lupus erythematosus (SLE) as compared to the general population, suggests a recent study published in the Journal of Rheumatology.
Danielle Korkus, Technion-Israel Institute of Technology, Haifa, Israel, and colleagues assessed the prevalence of SLE in a psoriatic arthritis (PsA) cohort and compared it to the general population using the database of a large healthcare provider.
For the purpose, the researchers analyzed the database of a PsA cohort (2002–2017), matched for age and sex, with randomly selected controls for demographics, clinical and laboratory manifestations, and dispensed medications. t test and chi-square test were used as appropriate for statistical analysis. In the PsA group, incidence density sampling was performed matching PsA patients without SLE as controls to each case of PsA with SLE by age and follow-up time. Factors affecting SLE development were assessed using univariable and multivariable conditional logistic regression analyses.
