IntroductionLimited data are available on sex differences in the disease characteristics, burden and treatment outcomes of early psoriatic arthritis (PsA). The "Spondyloarthritis Italian Registry: Evidence from a National Pathway" (SIRENA) study is a prospective, observational, Italian study conducted in 23 Rheumatology sites on patients with recent diagnosis of spondyloarthritis and na & iuml;ve to any disease-modifying antirheumatic drugs (DMARDs).MethodsThe study included 203 patients with early PsA, observed per clinical practice, who were studied regarding the influence of sex on the disease presentation and the likelihood of achieving minimal disease activity (MDA). Clinical and patient-reported outcome (PRO) measures were collected at both study entry and each follow-up visit until 24 months.

Increasing age, male sex, new PsA diagnosis, mono-/oligoarticular involvement, low (<= 14) Disease Activity index for PSoriatic Arthritis (DAPSA) and low Health Assessment Questionnaire Disability Index (HAQ-DI) values showed potential associations with MDA achievement at 6 months in univariate analysis, but this was not significant in the multivariate model.ConclusionIn patients with PsA na & iuml;ve to DMARDs, sex considerably influences the clinical characteristics and outcomes.Trial Registration NumberNCT03131661.
