Diagnosis and Management of Microscopic Colitis in Pediatric Patients

Area of Science:

• Gastroenterology
• Pediatric Pathology
• Inflammatory Bowel Disease

Background:

• Microscopic colitis (MC) presents as chronic watery diarrhea, distinct histologic findings, and normal endoscopic appearance.
• MC is a common cause of diarrhea in adults but infrequently reported in pediatric populations.
• Non-specific symptoms and rarity in children necessitate increased awareness for timely diagnosis.

Purpose of the Study:

• To review epidemiology, risk factors, clinical features, and diagnosis of pediatric MC.
• To discuss current theories on pathogenesis and their impact on management.
• To outline suggested management strategies for pediatric MC, focusing on symptom control and minimizing treatment adverse effects.

Main Methods:

• Literature review of microscopic colitis in the pediatric population.
• Synthesis of data on epidemiology, clinical presentation, diagnostic methods, pathogenesis theories, and treatment approaches.
• Focus on evidence relevant to pediatric patients and clinicians.

Main Results:

• MC diagnosis in children requires colonoscopy with biopsy due to normal endoscopic findings.
• Etiology is not fully understood, but pathogenesis theories guide treatment.
• Management aims for symptomatic improvement, minimizing adverse effects, and sustained remission, potentially requiring maintenance therapy.

Conclusions:

• Increased awareness among pediatric clinicians and pathologists is crucial for diagnosing rare pediatric MC.
• Timely diagnosis through colonoscopy and biopsy is essential.
• Effective management involves symptomatic control, minimizing treatment risks, and addressing potential recurrence with maintenance therapy.
