IntroductionSexual dysfunction (SD) is prevalent in multiple sclerosis (MS) patients and affects quality of life. Furthermore, lower urinary tract dysfunction (LUTD) is common in MS patients.AimsThis study aims to evaluate the relationship between SD, neurological disability, depression, anxiety, and urodynamic alterations in patients with MS and LUTD.MethodsFrom January 2011 to September 2013, 135 consecutive patients with MS in remission phase and LUTD underwent first urodynamic examination, according to the International Continence Society criteria. Depression and anxiety were evaluated with the Hamilton Depression Scale (HAM-D) and the Hamilton Anxiety Scale (HAM-A), neurological impairment was assessed using the Expanded Disability Status Scale (EDSS), and SD was investigated with the Female Sexual Function Index (FSFI) or the International Index of Erectile Function (IIEF-15).Main Outcome MeasuresMultivariate logistic regression analyses were carried out to identify variables for predicting female sexual dysfunction (FSD) (FSFI < 26.55), male SD (IIEF-15 < 60), or moderate-severe erectile dysfunction (IIEF-EF ≤ 16), after adjusting for confounding factors.ResultsTotal IIEF-15 and all subdomains (all P < 0.01), total FSFI, FSFI-arousal, FSFI-lubrication, and FSFI-orgasm (all P < 0.05) were lower in subjects with EDSS ≥ 4.5. We found inverse relationship between IIEF-15 and relative subdomains with EDSS (all P < 0.01) and between FSFI and relative subdomains with EDSS (all P < 0.01), HAM-D (all P < 0.01), and HAM-A (all P < 0.01). Continuous EDSS (odds ratio [OR] = 1.54; P = 0.03) and categorical EDSS (≥4.5) (OR = 6.0; P = 0.03), HAM-D (OR = 4.74; P = 0.03), and HAM-A (OR = 4.10; P = 0.02) were significantly associated with FSD (FSFI < 26.55). Detrusor overactivity (DO) was an independent predictor of moderate-severe ED (IIEF-EF ≤ 16) (OR = 2.03; P < 0.01), and of FSD (OR = 9.73; P = 0.04).ConclusionsNeurological disability, depression and DO are significantly predictive of SD in MS patients, irrespective of gender. An EDSS ≥ 4.5 may significantly predict the presence of SD.© 2014 International Society for Sexual Medicine.
