The Meta-analysis of Gut and Vitamin D

All items in categories Intervention AND Gut


Overview Gut and vitamin D has the following summary

  • Gut problems result in reduced absorption of Vitamin D, Magnesium, etc.
  • Celiac disease has a strong genetic component.
    • Most, but not all, people with celiac disease have a gene variant.
    • An adequate level vitamin D seems to decrease the probability of getting celiac disease.
    • Celiac disease causes poor absorption of nutrients such as vitamin D.
    • Bringing the blood level of vitamin D back to normal in patients with celiac disease decreases symptoms.
    • The prevalence of celiac disease, not just its diagnosis, has increased 4X in the past 30 years, similar to the increase in Vitamin D deficiency.
  • Review in Nov 2013 found that Vitamin D helped
    Many intervention clinical trials with vitamin D for Gut problems (101 trials listed as of Sept 2019)

BACKGROUND:
Vitamin D deficiency is highly prevalent among patients with IBD, however, data on its association with clinical outcomes are conflicting.

AIM:
To perform a systematic review and meta-analysis to explore the association of low vitamin D status with clinical outcomes in patients with IBD.

METHODS:
We searched PubMed, Embase, Scopus and Web of Science from inception to February 2018 for observational studies evaluating the association of low 25(OH)D status on IBD disease activity, mucosal inflammation, clinical relapse and quality of life. Odds ratios (ORs) were pooled and analysed using a random effects model.

RESULTS:
Twenty-seven studies were eligible for inclusion comprising 8316 IBD patients (3115 ulcerative colitis, 5201 Crohn's disease). Among IBD patients, low 25(OH)D status was associated with increased odds of

  • disease activity (OR 1.53, 95% CI 1.32-1.77, I2 = 0%),
  • mucosal inflammation (OR 1.25, 95% CI 1.06-1.47, I2 = 0%),
  • low quality of life (QOL) scores (OR 1.30, 95% CI 1.06-1.60, I2 = 0%) and
  • future clinical relapse (OR 1.23, 95% CI 1.03-1.47, I2 = 0%).

In subgroup analysis, low vitamin D status was associated with

  • Crohn's disease activity (OR 1.66, 95% CI 1.36-2.03, I2 = 0%),
  • mucosal inflammation (OR 1.39, 95% CI 1.03-1.85, I2 = 0%),
  • clinical relapse (OR 1.35, 95% CI 1.14-1.59, I2 = 0%), and
  • low QOL scores (OR 1.25, 95% CI 1.04-1.50, I2 = 0%) and
  • ulcerative colitis disease activity (OR 1.47, 95% CI 1.03-2.09, I2 = 0%) and
  • clinical relapse (OR 1.20, 95% 1.01-1.43, I2 = 0%).


CONCLUSIONS: Low 25(OH)D status is a biomarker for disease activity and predictor of poor clinical outcomes in IBD patients.
