Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • 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.

    30 weeks

  • disease activity

    modified Mayo score,mild: 3 to 5, moderate: 6 to 10, severe: 11 to 12

    30 weeks

Secondary Outcomes (1)

  • drug survival

    54 week

Study Arms (2)

supplementary group

take vitamin D supplementation (400 IU/day) during VDZ treatment
