Abstract

Objective: To estimate the prevalence of psychiatric disorders in patients with systemic lupus erythematosus (SLE) and explore their association with anti-ribosomal P (anti-P) antibodies. Methods: Seventy-one consecutive female SLE patients without neurological manifestations were evaluated for psychiatric disorders using the Structured Clinical Interview for DSM-IV (SCID). Anti-P antibodies were measured by enzyme-linked immunosorbent assay (ELISA)/immunoblot analysis. Results: The mean age of subjects was 34.8 years (SD: 10.1 years), and the mean duration of SLE was 9.8 years (SD: 6.5 years). The 30-day prevalences of psychiatric disorders were: mood disorders 26.8%, anxiety disorders 46.5%, adjustment disorders 8.4%, alcohol abuse 1.4%, and somatoform disorder 1.4%. The lifetime prevalences of psychiatric disorders were: mood disorders 69%, anxiety disorders 52.1%, alcohol abuse 1.4%, and somatoform disorder 1.4%. Subjects with and without psychiatric manifestations did not differ regarding SLE clinical and laboratorial parameters including presence or absence of anti-P antibodies (23.1% vs. 20%, respectively, p = 1.0), disease activity, as measured by the Systemic Lupus Erythematosus Disease activity Index (4.08 ± 5.7 vs. 4.95 ± 6.3 respectively, p = 0.60) and cumulated damage, as measured by the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (0.7 ± 2.3 vs. 0.3 ± 0.7 respectively, p = 0.33). Conclusions: Mood and anxiety disorders are the most frequently observed psychiatric disorders in female SLE patients without concomitant neurological manifestations. These mild/moderate forms of psychiatric disorders are not associated with anti-P antibodies in SLE patients. Our findings reinforce the importance of systematic psychiatric evaluation for these patients in order to provide adequate and comprehensive care.
