Sulfasalazine-induced colitis complicating idiopathic ulcerative colitis
Canadian Medical Association Journal
|July 1, 1984
Summary
This case study highlights a pediatric ulcerative colitis patient unresponsive to sulfasalazine. Treatment with parenteral nutrition and prednisone proved effective, with sulfasalazine reintroduction triggering symptom recurrence.
Area of Science:
- Pediatric Gastroenterology
- Inflammatory Bowel Disease Research
Background:
- Idiopathic ulcerative colitis (UC) diagnosis in a previously healthy 9-year-old boy.
- Initial symptoms persisted despite standard sulfasalazine therapy.
Observation:
- Treatment with parenteral nutrition and prednisone (40 mg daily) led to symptom resolution.
- Metronidazole was administered for persistent Dientamoeba fragilis infection.
- Symptoms resolved within 3 weeks, with gradual prednisone tapering.
Findings:
- Sulfasalazine challenge on two separate occasions precipitated immediate recurrence of bloody diarrhea and UC histological features.
- Discontinuation of sulfasalazine led to symptom resolution, confirming a causal link.
Implications:
- Suggests potential sulfasalazine intolerance or adverse reaction in some pediatric UC cases.
- Highlights the efficacy of parenteral nutrition and corticosteroids in refractory pediatric UC.
- Underscores the importance of considering medication-induced exacerbations in UC management.
