This study reports on collagenous colitis, a chronic watery diarrhea condition. Effective treatments include dietary fiber, sulphasalazine, prednisone, or budesonide, leading to symptom resolution.
Area of Science:
- Gastroenterology
- Histopathology
Background:
- Collagenous colitis is a chronic disorder characterized by watery diarrhea.
- Its etiology and pathogenesis remain largely unknown.
- Macroscopically normal mucosa is observed, with characteristic histological findings.
Observation:
- Two female patients (54 and 67 years) presented with prolonged watery diarrhea.
- Physical, blood, fecal, and endoscopic examinations were unremarkable.
- Intestinal biopsies revealed a thickened subepithelial collagenous layer and increased intraepithelial lymphocytes.
Findings:
- Histological examination confirmed collagenous colitis in both patients.
- Treatment with a high-fiber diet, sulphasalazine, and either prednisone or budesonide resolved symptoms.
- Budesonide has recently shown promising clinical and histological effects.
Implications:
- Collagenous colitis requires specific diagnostic approaches beyond standard examinations.
- A multi-faceted treatment strategy, including newer agents like budesonide, can effectively manage symptoms.
- Further research into the pathogenesis of collagenous colitis is warranted.

Chronic Bowel Disorders: Introduction
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
Inflammatory 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...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
