Insights
This study found that vitamin D levels are higher in Behcet's disease patients than in healthy controls. Increased vitamin D may be linked to a lower risk of active Behcet's disease.
Area of Science:
- Rheumatology
- Immunology
- Endocrinology
Background:
- Behcet's disease (BD) is a chronic, multisystem inflammatory disorder of unclear origin.
- Vitamin D's role in inflammatory and autoimmune conditions is increasingly recognized.
- This study investigates the association between vitamin D status and Behcet's disease activity.
Approach:
- A systematic review and meta-analysis was conducted following PRISMA guidelines.
- Included observational studies assessed 25(OH)D concentrations in Behcet's disease patients.
- Data from 12 studies involving 1265 participants were analyzed.
Key Points:
- Patients with active Behcet's disease exhibited significantly lower serum vitamin D levels compared to those with inactive disease.
- Overall, Behcet's disease patients showed significantly higher serum vitamin D levels than healthy controls.
- A total of 341 publications were initially screened, with 12 studies ultimately included in the meta-analysis.
Conclusions:
- The findings support the hypothesis that higher serum vitamin D levels are associated with a reduced risk of active Behcet's disease.
- Further research into vitamin D supplementation for Behcet's disease management is warranted.
Objective:
Behcet's disease (BD) is a chronic multisystem inflammatory disease classified as Variable Vessel Vasculitis with unclear etiology. We designed this systematic review and meta-analysis to evaluate vitamin D status in Behcet's disease patients with this background.
Methods:
We performed this systematic review and meta-analysis according to PRISMA guidelines. We included all observational studies in humans published in English, evaluating the association of 25(OH)D concentrations in Behcet's patients. Two reviewers (HRK and AE) independently searched the databases and screened articles based on their titles and abstracts. A third reviewer resolved all disagreements. We performed analysis using Cochrane Program Review Manager Version 5.3. The protocol for this review was registered on PROSPERO (CRD42020197426).
Results:
A total of 341 publications were initially identified according to the search strategy. Finally, 12 publications were included in the meta-analysis. We performed this meta-analysis on 1265 participants from different studies with a sample size ranging from 63 to 224 individuals. In studies comparing active and inactive subgroups of patients with Behcet's disease, we found a significantly lower serum level of vitamin D in patients with Active BD (-0.4; 95% CI: -0.61, -0.25; p<0.001). We found that the serum level of vitamin D in Behcet's disease is significantly higher than in health controls (0.5; 95% CI: 0.15, 0.50; p=0.001).
Conclusion:
We demonstrated that the existing evidence is consistent with the hypothesis that an increased serum level of vitamin D would be associated with a substantially lower risk of active Behcet's disease.
