Brief Summary

Aims:Prospectively observe the effects of Vitamin D drops supplementation on the chronic course of ulcerative colitis patients, analyze whether the effect of Vitamin D drops on UC patients is affected by factors such as disease site, disease activity, treatment, etc.Exploring the relationship between Fok I gene polymorphism and the efficacy of vitamin D supplementation. Provide a certain theoretical basis for "precision treatment" for UC patients in the future. Design:It is a prospective cohort study. Investigators include a total of 100 participants with UC according to the inclusion and exclusion criteria, and divide them into two groups to assess their initial disease activity and detect related indicators. At the same time,investigators detect the Fok I gene polymorphism in all participants.One group is given Vitamin D drops 400IU per day orally, and the control group do not intervene. Participants' disease activity is assessed at baseline and related indicators are determined. The disease activity is re-evaluated in the 3rd, 6th, 9th, and 12th months, and the serum indexes are re-evaluated.Investigators use statistical methods to analyze whether Vitamin D drops supplementation treatment can increase the serum 25 (OH) D level of UC participants, improve the condition of UC participants,relationship with Fok I gene polymorphism,and analyze the effects of Vitamin D drops on participants with UC is affected by factors such as disease site, disease activity, and treatment.

Outcome Measures

Primary Outcomes (2)

  • Genotype frequency of vitamin D receptor single nucleotide polymorphisms in participants

    Genotype frequency of vitamin D receptor single nucleotide polymorphisms in participants can reflect whether it is related to the severity of the disease and how much relevance.

    1 year

  • 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

    1year

Secondary Outcomes (3)

  • Blood calcium and phosphorus

    1year

  • erythrocyte sedimentation rate

    1year

  • Concentration of C-reactive protein in participants

    1year

Study Arms (2)

Vitamin D drops

EXPERIMENTAL

This group of patients are going to supplemented with Vitamin D drops 400IU / d orally.

Drug: Vitamin D drops

Control

NO INTERVENTION

The other group do not interfere.

Interventions

Vitamin D-deficient UC patients are divided into two groups, one group is given orally with Vitamin D drops 400IU / d, while the other group do not interfere.

Vitamin D drops
