RESUMO
BACKGROUND: Psychiatric disorders have been extensively documented in patients with systemic lupus erythematosus (SLE). However, the prevalence of psychiatric disorders in patients with skin-restricted lupus (SRL) remains unknown, although SRL is more common than SLE. OBJECTIVES: To assess current and lifetime prevalence of Axis I psychiatric disorders among outpatients with SRL and to examine the factors associated with psychiatric disorders among such patients. METHODS: A multicentre case-control study involving outpatients with SRL and controls matched for sex, age and education level. The Mini International Neuropsychiatric Interview was used for psychiatric evaluation. RESULTS: We evaluated 75 patients and 150 controls. Of these, 49% of patients vs. 13% of controls fulfilled the criteria for at least one current psychiatric disorder (P < 0·001). The following disorders were significantly more frequent among patients than controls: current and lifetime major depressive disorder (9% vs. 0%, P < 0·001 and 44% vs. 26%, P = 0·01), generalized anxiety disorder (23% vs. 3%, P < 0·001 and 35% vs. 19%, P = 0·03), panic disorder (7% vs. 0%, P = 0·004 and 21% vs. 3%, P < 0·001), current suicide risk (24% vs. 7%, P = 0·003), alcohol dependence (7% vs. 0%, P = 0·004) and lifetime agoraphobia (20% vs. 9%, P = 0·01). Lupus duration and lupus past treatment by thalidomide were significantly higher among patients with current psychiatric disorders. CONCLUSIONS: This study demonstrates a high prevalence of several psychiatric disorders (anxiety, depression, suicide risk, alcohol dependence) in patients with SRL.
