Aim:
The aim of this study was to evaluate the long-term outcome of patients with collagenous colitis 10 years after the diagnosis.
Patients And Methods:
In 1989/1990, 65 patients were diagnosed to have collagenous colitis. Initially and after an interval of ten years these patients were asked to complete a questionnaire including onset and duration of diarrhea, stool frequency and consistency, other gastrointestinal symptoms including weight loss, drug history, treatment response and concomitant diseases.
Results:
Questionnaires from 47 patients (72.3 %) (female 40; mean age 68 years, range 41 - 95 years) were available for analysis. After a follow-up of ten years, 11 patients (23.4 %) had persistent diarrhea with no change of frequency and consistency compared to baseline. Four patients (8.5 %) showed a reduction of diarrhea frequency of at least 50 %. Diarrhea was resolved in 23 patients (48.9 %) during the follow-up period. Of those, 20 patients received anti-inflammatory treatment. After a complete resolution of diarrhea during the long-term follow-up, 9 patients (19.2 %) showed recurrence of diarrheal symptoms. None of the patients developed any malignancies of the GI-tract.
Conclusion:
The long-term outcome of CC is benign with a resolution of diarrhea in up to 50 % of patients receiving anti-inflammatory treatment. About 30 % of patients may experience persistent diarrhea even 10 years after diagnosis. Our data confirm that CC is a chronic disorder with a variable course of symptoms during a long-term follow-up.

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
