RESUMO
OBJECTIVES: To assess and compare sexual dysfunction (SDF) in female patients with systemic sclerosis (SSc) or systemic lupus erythematosus (SLE), to correlate sexual function with disease characteristics and depression, and to evaluate a short questionnaire (Qualisex) as a screening test. METHODS: Female patients with systemic sclerosis or systemic lupus erythematosus in two German tertiary university hospitals were evaluated in a prospective study. A self-designed questionnaire, the Female Sexual Function Index (FSFI), the Qualisex, and the Beck's depression inventory were used. RESULTS: 171 female patients were included into the study (83 with SSc, and 88 with SLE). 62.6% (52 of 83) of SSc patients and 67.0% (59 of 88) of SLE patients were sexually active. Only 9.6% of SSc patients and 14.8% of SLE patients had ever discussed sexual problems with their physician. Significantly more SSc patients would wish to discuss sexuality with their physician more intensively (37.3% vs. 28.4% in SLE patients, p=0.011). Among the 51 sexually active and evaluable SSc patients a mean FSFI of 25.53 (±5.06) was found, with a FSFI value defining sexual dysfunction (SDF) (<26.55) in 49% of patients, which did not differ significantly compared to SLE patients (n=59, mean FSFI 26.92 (±5.17), SDF in 45.8%). The Qualisex correlated significantly with the FSFI, and both Qualisex and FSFI correlated with depressiveness. CONCLUSIONS: Sexual dysfunction (SDF) is a frequent problem in female patients with SSc and SLE. Addressing sexual issues during medical consultation is an unmet need. The Qualisex constitutes a short questionnaire, which is suitable for addressing concerns on sexuality.
