INTRODUCTION: Over the last decade an increase in Clostridium difficile associated diarrhoea (CDAD) has been observed among Caucasians (1%). The frequency of CDAD is very high in Caucasian IBD patients; 8.7% in one study of IBD patients in remission. This has led to guidelines recommending routine screening for CDAD in IBD. Clinical impressions are that CDAD is rare among Sri Lankans. AIMS: This study was conducted to determine the frequency of CDAD in a cohort of Sri Lankan IBD patients and healthy controls. METHODS: Cases [n=154] were histologically confirmed IBD patients, in clinical remission. The controls [n=100) were non-IBD patients who presented to medical clinics without diarrhoea and with no exposure to antibiotics for up to 8 weeks prior to recruitment. Immunoassays for Clostridium difficile toxins A and B were performed on stool samples obtained from both groups. RESULTS: The frequency of CDAD was 0.7% (n=l) and 0% (n=0) in IBD patients and controls respectively. CONCLUSIONS: Compared to Caucasians, CDAD was very rare in this cohort of Sri Lankans, including those with IBD. Routine screening for CDAD does not seem necessary in our setting.
