About this study
Official title: Observation of the Effect of Vitamin D Supplementation on Chronic Course of Patients With Ulcerative Colitis Based on Vitamin D Receptor Fok I Gene Polymorphism,a Prospective Cohort Study
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.
Read the detailed description
- The research can be started only after approval by the Medical Ethics Committee of the Second Affiliated Hospital of Wenzhou Medical University.
- According to the "Consensus on Diagnosis and Treatment of Inflammatory Bowel Disease" formulated by the Beijing Conference in 2018 as a standard, patients with clear diagnosis of UC are collected.Other diagnostic criteria include Vitamin D deficiency (<= 20ng / ml). Exclusion criteria included pregnancy, breastfeeding, liver and kidney dysfunction, concurrent autoimmune diseases, and use of antiepileptic drugs or drugs metabolized by liver cytochrome P450 enzymes.
- Assess disease activity of UC participants based on the "Moya score".
- General information about participants with UC is collected.
- Detection of Fok I gene polymorphism using Snapshot technology.
- The level of serum 25 (OH) D of participants is detected.
- Serum C-reactive protein, erythrocyte sedimentation rate, albumin, calcium and phosphorus levels are measured.
- Develop a treatment plan for all participants.
- Participants are divided into two groups, one group is given oral Vitamin D drops 400IU/ d, and the other group do not intervene.
- The disease activity is re-evaluated in the 3rd, 6th, 9th, and 12th months, and the above serum indexes are re-evaluated.
- Follow-up for 12 months. By comparing the above indicators, observe that in the Han population:
- Can Vitamin D drops supplementation increase serum 25 (OH) D levels in patients with UC?
- Can Vitamin D drops supplementation improve the condition of patients with UC?
- Whether Fok I gene polymorphism affect the efficacy of Vitamin D drops supplementation therapy?
- Whether the effects of Vitamin D drops on UC patients is affected by factors such as disease site, disease activity, treatment, etc ..
- Through statistical analysis, comprehensive analysis of the effectiveness and safety of Vitamin D drops supplementation in Han patients with UC, and its relationship with Fok I gene polymorphism, providing a theoretical basis for further "precise treatment" intervention in inflammatory bowel disease.
- Being tested
- Vitamin D drops
- Medical subject headings
- Colitis, Ulcerative, Vitamin D Deficiency
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Vitamin D dropsDrug
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.
| Study group | Role | What they receive |
|---|---|---|
| Vitamin D drops | Experimental | This group of patients are going to supplemented with Vitamin D drops 400IU / d orally. Receives: Drug: Vitamin D drops |
| Control | No intervention | The other group do not interfere. |
What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 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
Measured: 1year
Secondary outcomes (3)
Blood calcium and phosphorus
Monitoring serum calcium and phosphorus levels to prevent toxic side effects.
Measured: 1year
erythrocyte sedimentation rate
ESR can be used to reflect the degree of inflammation in the body.
Measured: 1year
Concentration of C-reactive protein in participants
Concentration of C-reactive protein can be used to reflect the degree of inflammation in the human body.
Measured: 1year

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Vitamin D drops in people with Ulcerative Colitis and Vitamin D Deficiency, run by Second Affiliated Hospital of Wenzhou Medical University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 16 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Jiang yi, PhD (0086-13676715542, wzjiangyi@yeah.net), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Genotype frequency of vitamin D receptor single nucleotide polymorphisms in participants (time frame: 1 year). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Mar 2020.
