About this study
Official title: Retrospective Analysis of the Effect of Vitamin D Supplementation on the Clinical Efficacy of Vedelizumab in Ulcerative Colitis Patients
It is uncertain whether vitD3 supplementation is beneficial for the remission of ulcerative colitis (UC). The effects of vitD3 supplements on the efficacy of vidrecizumab in Chinese UC patients were retrospectively analyzed. Methods: Patients with moderate to severe UC were recorded. These patients were initially treated with VDZ. VitD3 supplementation was defined as 400IU/d vitD3 supplementation during the first infusion of VDZ and continued throughout the follow-up period. Disease activity was assessed using the modified Mayo score.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| supplementary group | take vitamin D supplementation (400 IU/day) during VDZ treatment | |
| non-supplementary group | Not described |
What is being measured
The primary outcome is the main question the study is designed to answer.
Serum 25 (OH) D level
Because serum 25 (OH) D levels are relatively stable, they are considered the most reliable indicator of vitamin D status.
Measured: 30 weeks
disease activity
modified Mayo score，mild: 3 to 5, moderate: 6 to 10, severe: 11 to 12
Measured: 30 weeks
Secondary outcomes (1)
drug survival
Proportion of UC patients who continued to receive VDZ
Measured: 54 week
