Does serum 25 hydroxy vitamin D level predict disease activity in ulcerative colitis patients?

Area of Science:

• Gastroenterology
• Endocrinology
• Immunology

Background:

• Ulcerative colitis (UC) is a chronic inflammatory bowel disease with complex etiology.
• The role of serum 25-hydroxy vitamin D (25(OH)D) in UC disease activity remains controversial.
• Understanding factors influencing UC severity is crucial for effective patient management.

Purpose of the Study:

• To investigate the correlation between serum 25(OH)D levels and disease activity in ulcerative colitis (UC) patients.
• To clarify the controversial findings regarding vitamin D status and UC severity.
• To provide insights into potential therapeutic targets for managing UC.

Main Methods:

• A cohort of UC outpatients was enrolled and diagnosed by gastroenterologists.
• Exclusion criteria addressed factors affecting vitamin D levels (e.g., intake, absorption, metabolism).
• Disease activity was classified using the Truelove and Witts criteria.

Main Results:

• Fifty UC patients (mean age 36.98 years) were analyzed.
• Serum 25(OH)D levels were significantly higher in patients with mild UC activity compared to moderate activity.
• Lower 25(OH)D concentrations were associated with a higher likelihood of moderate UC disease activity (β=0.37, p=0.04).

Conclusions:

• A lower serum 25(OH)D level may be linked to increased disease activity in mild-to-moderate ulcerative colitis.
• Vitamin D status could be a relevant biomarker for UC severity.
• Further research is warranted to explore the therapeutic potential of vitamin D supplementation in UC.
