Background The prevalence of erectile dysfunction (ED) in ankylosing spondylitis (AS) patients was reported rarely and with small sample. Aim The study sought to explore the prevalence of ED in men with AS and to determine whether AS is a risk factor for ED. Methods A systematic search was conducted in the China National Knowledge Infrastructure, Wanfang, VIP Database, CBM, PubMed, Web of Science, and Cochrane Library. The search was restricted to the articles published up to October 2022. Assessment tools adapted for prevalence studies were used to evaluate the quality of cross-sectional studies, and the quality of case-control studies was assessed by Newcastle–Ottawa scale. The relative risk (RR) and the standard mean difference (SMD) were used to evaluate the association between AS and ED. The subgroup analyses were conducted to identify the resources of heterogeneity. The sensitivity analysis was performed to assess the stability of the pooled estimates. Data were analyzed and graphed using STATA 16.0. Outcomes The pooled prevalence of ED in AS patients was calculated and the RR and the SMD were used to evaluate the association between AS and ED. Results A total of 393 AS patients, enrolled in the 8 included studies, were assessed for the prevalence of ED. The pooled ED prevalence estimate was 44% (95% confidence interval [CI], 25% to 63%, P < .001) with the statistical heterogeneity (I2 = 95.1%, P < .001). After pooling the data for RR, the results showed that men with AS were at a significantly higher risk for ED when compared with the general population without AS (RR, 2.04; 95% CI, 1.28 to 3.25, P = .003; heterogeneity: I2 = 72.6%, P = .003). The pooled results of 5 studies, which provided the International Index of Erectile Function (IIEF) score, demonstrated that patients with AS had significantly lower values in the IIEF erectile function domain as compared with the healthy control subjects (SMD, −0.60; 95% CI, −0.80 to −0.41; P < .001; heterogeneity: I2 = 34.4%, P = .192). Additionally, the other domain of the IIEF also showed lower values when compared with the general population without AS (P < .05). Clinical Implications The present meta-analysis provides evidence of the management of ED in men with AS. Strengths and Limitations This is the first meta-analysis to provide the prevalence of ED in AS patients and to demonstrate that AS is a risk factor for ED. However, the results after pooling the included studies showed significant heterogeneity. Conclusion Our meta-analysis demonstrated the high prevalence of ED in men with AS and that AS is a potential risk factor for ED.

Introduction/Objective. Patients with AS often experience chronic musculoskeletal pain, fatigue and stiffness, which may contribute to psychological distress and sexual dysfunction. This study aims to assess prevalence of ED in patients with AS and identify potential associations between clinical parameters related to AS with the presence of ED. Methods. Forty consecutive male patients with the AS (mean age 42.8 ? 8.9 years) and 60 healthy men (mean age 38.9 ? 10.9 years) were included. All subjects filled-in the International Index of Erectile Function (IIEF) questionnaire, as well as the Beck anxiety inventory (BAI) and the Beck depression inventory (BDI). In patients with AS disease activity was evaluated using the Ankylosing Spondylitis Disease Activity Score (ASDAS) and the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), functionality using the Bath Ankylosing Spondylitis Functional Index (BASFI), and quality of life using the Ankylosing Spondylitis Quality of Life (ASQoL) questionnaire. Results. ED was significantly more frequent in patients with AS compared to controls (52.5%: 25%, p = 0.049). AS patients with ED had more severe symptoms of depression, than AS patients without ED (p = 0.034). Ac-cording to ASQoL scores, patients with AS and ED had a worse quality of life, compared to patients with AS without ED (p = 0.022). The increase in one unit of ASQoL increased the odds of having ED for 17.5% (p = 0.035). Conclusion. ASQoL score, as a measure of quality of life, was the only independently associated parameter with the presence of ED. It is necessary to raise awareness of ED in patients with AS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
