About this study

Official title: Influence of Vitamin D3 Supplementation on Infliximab Efficacy in Chinese Patients With Crohn's Disease: A Retrospective Cohort Study

Background: It remains uncertain whether vitD3 supplementation is beneficial for remission of Crohn's disease (CD). The influence of vitD3 supplementation on Infliximab (IFX) efficacy was retrospectively analyzed in Chinese CD patients. Methods: Patients with moderate-to-severe CD, who were bio-naïve and prescribed with IFX treatment for at least 54 weeks were recorded. VitD3 supplementation was defined as patients additionally took oral vitD3 (125 IU/d) within 3 days after the first infusion and persisted in the whole follow-up period. Disease activity was assessed using Harvey-Bradshaw Index (HBI). Serum cytokine profiles were quantitatively analyzed in a subset of all patients at baseline and 54-week after intervention.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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: 54 weeks

  2. disease activity

    CDAI evaluation

    Measured: 54 weeks

Secondary outcomes (2)
  1. the metabolism of calcium and phosphorus

    serum levels calcium and phosphorus

    Measured: 54 weeks

  2. the expression profiles of Th-cell-related cytokines

    Serum levels of IL-2, IL-4, IL-6, IL-10, TNF-α and IFN-γ

    Measured: 54 weeks

What does the primary outcome measure?

Serum 25 (OH) D level (time frame: 54 weeks). 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?

On the ClinicalTrials.gov record for NCT04606017, which also lists 1 linked publication.

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.
