Abstract [en]

OBJECTIVE: The long-term natural history of collagenous colitis (CC) and lymphocytic colitis (LC) is not well known. The few reports available that address these issues have a limited follow-up. The aims of this study were to evaluate the natural history of microscopic colitis (MC), to describe the treatment medications prescribed and to assess the use of non-steroidal anti-inflammatory drugs (NSAIDs) in MC. MATERIAL AND METHODS: This study is based on an earlier epidemiological study conducted in Iceland where 125 patients with MC (71 with CC and 54 with LC) were diagnosed in the period 1995-99. All patients still alive and available were questioned about symptoms, treatment and NSAID use in the 3 months preceding the interview. RESULTS: In a mean follow-up time of 6.4 years from diagnosis, 15% of the patients had diarrhoeal symptoms more than once a week, 30% less than once a week and 55% had no diarrhoea. Abdominal pain was reported in 18% of the patients. There was no statistically significant difference in symptoms of CC and LC patients. Forty-eight patients (50%) were receiving medication for MC, 16% used aminosalicylates and 14% corticosteroids. Patients using medication for MC had significantly more diarrhoeal symptoms compared with those who did not (p = 0.002). Patients using NSAIDs regularly or as required, statistically did not have more symptoms related to MC than non-NSAID users. CONCLUSIONS: Only a minority of patients with MC had diarrhoea more than once a week in a long-term follow-up and the symptom pattern was similar between CC and LC patients. The use of NSAIDs was not associated with more diarrhoeal symptoms.
