The relationship between Crohn's disease and gallstones is established. However, the prevalence and risk factors for gallstones in patients with ulcerative colitis (UC) are not yet well understood. The aim of this study was to evaluate the prevalence and risk factors of gallstones in patients with UC.
This study was a retrospective single center study. A total of 87 patients with UC and 261 healthy controls were enrolled. Age, sex, and body mass index were matched. To investigate risk factors, the extent of UC, duration of disease, number of hospital admissions, and number of steroid treatments in patients with UC were evaluated.
The prevalence of gallstones in patients with UC was 13.8%, whereas that in healthy controls was only 3.1% (
This is the first study of gallstone prevalence in Korean UC patients. In this study, patients with UC had a higher prevalence of gallstones compared to that in well-matched healthy controls. Age seemed to be a possible risk factor, and more studies are needed. Further prospective, large-scale studies will be required to confirm the risk factors for gallstones in UC patients.

Vaccinations in patients with inflammatory bowel disease (IBD) are recommended to prevent infectious diseases. However, there are few reports of vaccination in IBD patients in Korea. The frequency of complementary and alternative medicine (CAM) use is high despite its uncertain effectiveness. This study aimed to identify the rates of vaccination and use of CAM in patients with IBD.
A total of 219 patients attended an education session for IBD patients held at Severance Hospital on March 23, 2013. We conducted a survey on vaccination and CAM use in IBD patients; 120 patients completed the questionnaire.
The influenza vaccination rate was 44.2% and pneumococcal vaccination rate was 4.2%. Thirty-one (66%) patients were aware of the importance of vaccination. The vaccination rate was higher in patients who were aware of the importance of vaccination compared with that in patients who were unaware of the importance of vaccination (70.1% vs. 41.7%,
Awareness of the importance of vaccination and actual vaccination rates were low in IBD patients. Despite insufficient evidence on the effectiveness of CAMs in IBD patients, many patients used CAMs. We believe that repeated education and promotion of vaccination are important. Further large-scale studies to investigate the efficacy and safety of CAMs are warranted in patients with IBD.
