Early and late onset ulcerative colitis: distinct clinical features

Area of Science:

• Gastroenterology
• Internal Medicine
• Clinical Research

Background:

• Ulcerative colitis (UC) is a chronic inflammatory bowel disease.
• Disease onset can occur at various ages, influencing clinical presentation and treatment response.

Purpose of the Study:

• To compare the clinical characteristics and treatment outcomes of early-onset versus late-onset ulcerative colitis.
• To identify distinct features of ulcerative colitis based on age of symptom onset.

Main Methods:

• Retrospective review of 93 patients diagnosed with ulcerative colitis.
• Categorization of patients into early-onset (21-30 years) and late-onset (≥51 years) groups.
• Analysis of disease location, symptoms, treatment response, and demographic factors.

Main Results:

• Late-onset UC (50.5% early-onset, 27.9% late-onset) showed a predilection for proctocolitis and liver involvement, with more bowel movements daily.
• Late-onset disease had a more protracted initial episode and shorter remission periods, often requiring systemic corticosteroids.
• Extensive colitis was more common in females; early-onset female UC patients exhibited increased severity markers and higher need for systemic therapy.

Conclusions:

• Late-onset ulcerative colitis is clinically distinct, characterized by distal colonic involvement and relative refractoriness to therapy.
• Early-onset ulcerative colitis in females may present with more severe systemic manifestations.
• Age at onset is a critical factor in understanding ulcerative colitis heterogeneity and guiding therapeutic strategies.
