Longitudinal Study of Sexual Dysfunction in Men and Women with Inflammatory Bowel Disease Initiating Biologic or Small Molecule Therapy.

BACKGROUND

Patients with inflammatory bowel disease (IBD) experience increased rates of sexual dysfunction (SD). This study investigated SD longitudinally in patients initiating a biologic or small molecule therapy.

METHODS

Patients with Crohn's disease (CD) or ulcerative colitis (UC) starting biologic or small molecule therapy were surveyed at induction, 2 months, and 6 months. Measures included the IBD-Female and Male Sexual Dysfunction Scales (FSDS, MSDS), PROMIS Sexual Function and Satisfaction Brief Profile, Harvey Bradshaw Index (HBI), Simple Clinical Colitis Activity Index (SCCAI), partial Mayo score, Short IBD Questionnaire (SIBDQ), PHQ-9, and IBD Disability Index (IBDDI). Endoscopic and biomarker data were collected. Correlations, longitudinal changes, and predictors of SD were analyzed.

RESULTS

A total of 170 patients (89 males, 81 females) completed baseline surveys, 132 at 2 months, and 115 at 6 months. Median age was 31.5 years; 59% had CD. At baseline, median HBI was 5.5, SCCAI 6, and pMayo 4. SD scores correlated with clinical disease activity (p < 0.05) but not consistently with endoscopic or biomarker measures. SD was associated with impaired quality of life, depression, and disability (p < 0.05). Among responders to therapy, SD, SIBDQ, and IBDDI significantly improved (p < 0.05). Multivariate analysis showed that more severe clinical disease activity predicted worse SD, while time after therapy initiation and improved quality of life were independently associated with better SD.

CONCLUSIONS

Advanced therapy can improve SD in IBD. Improvements appear to be mediated by reductions in clinical disease activity and psychosocial factors.
