Prevalence and risk factors for gallstone and renal stone formation in patients with intestinal Behçet’s disease

Abstract

Background/Aims The association between inflammatory bowel disease (IBD) and gallstone and renal stone formation has been established. However, few studies have investigated this association in patients with intestinal Behçet’s disease (BD). We aimed to examine the prevalence of gallstones and renal stones in patients with intestinal BD and identify potential risk factors. Methods We analyzed gallstone and renal stone occurrences in 553 patients diagnosed with intestinal BD who had undergone cross-sectional imaging examinations between March 2005 and April 2021 at the IBD Center, Severance Hospital, Seoul, South Korea. Logistic regression models were used to identify risk factors for gallstone and renal stone formation. Results Of 553 patients over a mean 12.1-year duration, 141 (25.4%) patients had gallstones and 35 (6.3%) had renal stones. In multivariate logistic regression analysis, disease duration > 19 years (OR 2.91, 95% CI 1.56–5.44, p 19 years (OR 5.61, 95% CI 1.98–15.90, p = 0.001) and frequent hospitalization (> 3 times) (OR 3.29, 95% CI 1.52–7.13, p = 0.002). No significant correlation was observed between gallstone and renal stone occurrence. Conclusions These findings contribute to greater understanding concerning gallstone and renal stone prevalence and associated risk factors in patients with intestinal BD.
