Prospective study of colitis in infancy and early childhood
Insights
Diagnosing pediatric inflammatory bowel disease (IBD) in children under three is challenging. Colonoscopy and biopsy aid diagnosis in 60% of cases, revealing diverse colitis types requiring tailored treatments.
Area of Science:
- Pediatric Gastroenterology
- Inflammatory Bowel Disease (IBD) Research
- Gastrointestinal Pathology
Background:
- Inflammatory bowel disease (IBD) is uncommon in infants and very young children.
- Early diagnosis and management are crucial for long-term outcomes in pediatric IBD.
Purpose of the Study:
- To investigate the diagnostic yield of colonoscopy and biopsy in children aged 3 years or less with chronic inflammatory bowel disease.
- To characterize the types of colitis and assess treatment outcomes in this young patient cohort.
Main Methods:
- Retrospective analysis of 10 children (aged ≤3 years) diagnosed with chronic inflammatory bowel disease between 1973 and 1983.
- Diagnostic procedures included colonoscopy and mucosal biopsies.
- Treatment strategies varied based on diagnosis, with follow-up assessments at 6 months and 2 years post-treatment.
Main Results:
- Colonoscopy and biopsy established a firm diagnosis in 60% of cases.
- Diagnoses included ulcerative colitis (2), Crohn's disease (2), cow's milk-induced colitis (2), and indeterminate colitis (4).
- Treatment success varied: ulcerative colitis and Crohn's disease patients improved with medication; allergic colitis resolved with dietary changes; indeterminate colitis showed mixed responses, with one requiring colectomy.
Conclusions:
- Colitis in infancy and early childhood represents a heterogeneous group of conditions.
- Colonoscopy with mucosal biopsy is valuable for diagnosing colitis in very young children.
- Further biopsies may be needed to categorize indeterminate colitis effectively.
Abstract:
Ten of a total of 106 children with chronic inflammatory bowel disease seen between 1973 and 1983 were aged 3 years or less (9%). These are the subject of this study. Colonoscopy and biopsy revealed ulcerative colitis in two, Crohn's disease in two, cow's milk-induced colitis in two, and colitis of indeterminate type in four. The children were followed up and reassessed 2 years post-treatment. The four children with ulcerative colitis and Crohn's disease were asymptomatic 6 months after treatment with sulfasalazine and/or prednisolone. The two breast-fed infants with allergic colitis who were treated with cow's milk-free diet in baby and mother showed clinical, endoscopic, and histological resolution. One of the remaining four children with indeterminate colitis is well and off all treatment, and two are well with minimal symptoms and taking sulfasalazine. One child continued to have frequent relapses and subsequently had subtotal colectomy performed with clinical improvement. Histopathology showed features suggestive of intestinal Behcet's disease. The present study shows that colonoscopy and mucosal biopsy allow a firm diagnosis to be established in 60% of cases of this selected group of very young children. In our experience colitis in infancy and early childhood appears to be a heterogeneous group of conditions. An initial assessment of indeterminate colitis should be followed with multiple mucosal biopsies to attempt further categorization.
