Not applicable Interventional University of Veterinary and Animal Sciences, Lahore - Pakistan · NCT07269223

This trial will try giving fortnightly oral vitamin D3 alongside usual care to adults aged 20–40 with moderate ulcerative colitis in Pakistan to see if it lowers blood and stool markers of inflammation and improves symptoms.

What this trial studies

This is a randomized, placebo-controlled trial enrolling 60 adults (age 20–40) with moderate ulcerative colitis and severe vitamin D deficiency to receive either standard treatment plus oral vitamin D3 (50,000 IU every two weeks) or standard treatment with placebo for 12 weeks. Primary outcomes are changes in blood inflammatory markers (CRP, ESR, IL‑6), fecal calprotectin, and disease activity by the partial Mayo score. Secondary outcomes include serum vitamin D status, dietary intake, and quality of life measures. The trial is being conducted at the University of Veterinary & Animal Sciences in Lahore and focuses on the immune‑modulating, anti‑inflammatory effects of vitamin D3 as an adjunct to usual therapy.

Who should consider this trial

Good fit: Ideal candidates are adults 20–40 years old with moderate ulcerative colitis, severe vitamin D deficiency (<10 ng/mL), on stable medication for at least one month, able to consent, and able to attend visits at the Lahore site.

Not a fit: Patients with mild or severe UC, Crohn's disease or other autoimmune disorders, recent vitamin D supplementation, known kidney or liver disease, pregnant or breastfeeding women, or those outside the 20–40 age range are unlikely to benefit from this specific protocol.

Why it matters

Potential benefit: If successful, adding vitamin D3 to usual treatment could reduce intestinal inflammation and improve symptoms and quality of life for adults with moderate ulcerative colitis who are vitamin D deficient.

How similar studies have performed: Prior observational studies and some interventional trials suggest vitamin D can affect inflammation in IBD, but randomized evidence is mixed and trials specifically in severely deficient moderate UC patients are limited.
