- OBJECTIVE: To compare the relapse-preventing effect and the frequency of adverse events of olsalazine and sulphasalazine in sulphasalazine-tolerant patients with ulcerative colitis. METHODS: Patients in remission, with at least two episodes of active disease during the last 5 yr, were randomized to 2 g of sulphasalazine or 1 g of olsalazine daily and were followed for 6-18 months. Relapse rates in the two groups were compared using frequency and life-table analysis. Sixty-nine patients with proctitis, 140 with left-sided colitis, and 113 with subtotal or total colitis were evaluated. RESULTS: In the intention-to-treat analysis, the failure rate (relapses plus withdrawals) was 54.7% in the olsalazine and 47.2% in the sulphasalazine group. In the per-protocol analysis excluding withdrawals, 44.7% relapsed in the olsalazine and 39.3% in the sulphasalazine group. Remission curves did not differ significantly, although at all time intervals the frequency of remission was slightly higher in the sulphasalazine group (p = 0.19 in the intention-to-treat analysis and p = 0.42 in the per-protocol analysis estimated by the log-rank test). Twelve patients (of whom five had diarrhea) in the olsalazine group versus eight patients in the sulphasalazine group discontinued the study because of side effects. CONCLUSION: The relapse-preventing effect of olsalazine and sulphasalazine in sulphasalazine-tolerant patients did not differ. Furthermore, the tolerability of olsalazine, particularly concerning diarrhea, appears to be better than previously reported.

Mechanisms of diarrhoea in myotonic dystrophy
- 1998

In: European Journal of Gastroenterology and Hepathology. - : Ovid Technologies (Wolters Kluwer Health). - 0954-691X .- 1473-5687. ; 10:7, s. 607-10

- BACKGROUND: Gastrointestinal (GI) symptoms are common in myotonic dystrophy (MD). Diarrhoea is one of the more disabling of these GI complaints. The mechanisms behind diarrhoea in MD have not previously been investigated systematically. OBJECTIVE: To elucidate the mechanisms behind diarrhoea in MD. METHODS: Twenty patients with MD and suffering from diarrhoea were investigated in order to detect malabsorption (blood tests and faecal fat excretion) and bile acid malabsorption ([75Se]selenahomocholic acid-taurine (SeHCAT) retention) and to study intestinal morphology (duodenal and rectal biopsies). RESULTS: Two patients had deficiency of folic acid and four showed reduced levels of pancreatic isoamylase, but none of them had steatorrhoea. Two out of eight patients had abnormal bile acid breath tests with normal SeHCAT, indicating small bowel bacterial overgrowth and 12 displayed reduced SeHCAT retention. Duodenal biopsies were normal in eight patients and five out of nine rectal biopsies displayed slight inflammation. CONCLUSIONS: A possible mechanism of diarrhoea in MD could be identified in most of the patients. Bile acid malabsorption seems to be a frequent cause and can be treated successfully

Familial occurrence of microscopic colitis: a report on five families
- 2001
-
In: Scandinavian Journal of Gastroenterology. - : Informa UK Limited. - 1502-7708 .- 0036-5521. ; 36:9, s. 959-962

Journal article (peer-reviewed)abstract
- BACKGROUND: The etiology and pathogenesis of microscopic colitis is unknown. Whether genetic predisposition is of importance, as in many other gastrointestinal diseases, is unknown. Familial occurrence of collagenous colitis has earlier been reported only in two families. METHODS: Familial occurrence of microscopic colitis was searched for in a Swedish national microscopic colitis register. RESULTS: Familial occurrence of microscopic colitis was identified in five families. In all families a sister-sister relationship was found. Two sisters with collagenous colitis had been living apart in different Nordic countries for many years before developing the disease. In one pair, the smoking sister had collagenous colitis and the never smoking sister had lymphocytic colitis. CONCLUSIONS: Considering the relative rarity of microscopic colitis, these findings indicate that a genetic predisposition may be of importance.
