Abstract

Background Spondyloarthropathies (SpAs) are a group of auto-inflammatory diseases, with overlapping symptoms, that include ankylosing spondylitis (AS), psoriatic arthritis (PsA), undifferentiated spondyloarthritis (Und SpA), enteropathic arthritis, and reactive arthritis (1). Historically, SpAs have been viewed as diseases that predominantly affected men (2).

Objectives To analyze the influence of gender on disease patterns and therapeutic approach in a large cohort of Colombian patients with SpAs.

Methods A cross-sectional study was conducted in 621 patients with SpAs, in whom clinical and therapeutic characteristics were analyzed based on gender. Statistical association was examined by means of Chi-square tests, Mann-Whitney test, and logistic regression analyses.

Results The male-to-female ratio was 1,1:1 in this cohort. Younger age at diagnosis was found in males. AS was the most frequent disease (54,7%), followed by PsA (35,7%), and undifferentiated SpA (9,5%). The male gender was positively associated to the presence of AS (OR 2,29 95%IC 1,31–4,04), radiographic sacroilitis (OR 3,46 95%IC 1,82–6,56), HLAB27 positivity (OR 1,95 95%IC 1,31–2,91), low back pain (OR 1,85 95%IC 1,34–2,54) and axial involvement (OR 1,98 95%IC 1,42–2,77). According to the therapeutic profile, female gender was positively associated to the use of conventional DMARD therapy (i.e., methotrexate (p=0,03), leflunomide (p=0,0057), chloroquine (p=0,013)), while male patients were more associated to the use of biologic therapy.

General characteristics of patients with SpAs by gender

Conclusions In this Colombian large sample with SpA, male patients have a younger onset of disease, higher proportion of axial involvement, HLAB27 positivity, evidence of radiographic sacroilitis and higher use of anti-TNF therapy.
