RESUMO
BACKGROUND AND AIMS: There have been very few studies on inflammatory bowel disease (IBD) in Sri Lanka. This study was undertaken to determine the clinical presentation and whether a western style diet or infection with geo-helminths were associated with the condition. METHODS: Three questionnaires were given to the patients: one relating to diet, one relating to clinical presentation and one relating to quality of life. The disease was confirmed endoscopically and histologically. Faeces were examined for parasites. RESULTS: Forty four patients were enrolled (43-ulcerative colitis; 1-Crohn's Disease). All but one had ulcerative colitis. Most had no family history of disease. The peak age of onset was 21-40 y and 63% gave a history of more than 6 months symptoms prior to diagnosis. Clinical presentation was similar to cases in western countries although milder with less severe life-events. None of them had undergone surgery. All patients ate a rice-based diet and none ate bread made of refined flour. Only 2 patient was infected with a geo-helminth. CONCLUSIONS: Eating bread made of refined flour is not related to development of IBD in these patients. The prevalence of geo-helminths in the study population corresponded to the general population average. Delay in diagnosis occurs because of an initial assumption that the cause of symptoms is infective. A National Register of non-infectious gastrointestinal disease would aid the epidemiology and allocation of funding to this inflammatory condition.
