Association of Vitamin D Level With Disease Severity and Quality of Life in Newly Diagnosed Patients of Ulcerative Colitis: A Cross-Sectional Analysis

Abstract

IntroductionUlcerative colitis is an immunologically mediated disorder affecting the gastrointestinal tract. Vitamin D3 has been shown to modulate many immunological diseases, but its role in ulcerative colitis is not well documented. This study was done to find out if levels of vitamin D are associated with the severity of disease and quality of life in ulcerative colitis patients. MethodsThis cross-sectional study consists of two parts. The first part consists of having a comparative assessment of baseline parameters of newly diagnosed ulcerative colitis patients and healthy controls. The 2nd part consists of an evaluation of the association of levels of vitamin D3 with disease severity and quality of life in ulcerative colitis. Independent predictors of disease severity and quality of life were assessed using multiple linear regression. ResultsVitamin D levels were significantly lower in healthy controls compared to newly diagnosed ulcerative colitis patients. Median ulcerative colitis disease activity index score was significantly higher in the vitamin D deficient group compared with those who had normal vitamin D levels (p-0.001). Quality of life was also poor in the vitamin D deficient group compared to those with normal vitamin D levels (p-0.000). Vitamin D levels were found to be independent predictors of ulcerative colitis disease activity scores and health-related quality of life scores. ConclusionVitamin D may have some immunomodulating properties, which might be associated with decreased ulcerative colitis disease activity index and better quality of life.

The Effect of Empowering Education Combined With Mindfulness Meditation Training on Negative Emotion and Quality of Life in Patients With Inflammatory Bowel Disease

“…Inflammatory bowel disease (IBD) is a group of chronic, relapsing, and non-specific inflammatory diseases involving the gut ( Guan, 2019 ; Dash et al, 2021 ). Inflammatory bowel disease is clinically divided into ulcerative colitis (UC) and Crohn’s disease (CD) ( Lamb et al, 2019 ).…”

The correlation between serum 25-hydroxyvitamin D level and ulcerative colitis: a systematic review and meta-analysis

“…Meanwhile, patients with UC with a long illness had significantly lower serum vitamin D levels than those with a short illness. Other studies have shown that patients with UC who are vitamin D deficient have worse quality of life than those who are vitamin D adequate [27].…”
