Association of benign paroxysmal positional vertigo with vitamin D deficiency: a systematic review and meta-analysis.

What It Covers

This meta-analysis looks at Vitamin D, K2, Magnesium and Zinc.

Benign paroxysmal positional vertigo (BPPV) is an idiopathic recurrent inner ear illness that is caused most often by an imbalance in the metabolism of calcium carbonate crystals (otoconia) inside the semicircular canals, in which the otoconia begin to circulate freely after being dislodged from the basic structure.

The underlying etiology of this imbalance has not yet been well established; however, a few recent articles have revealed that vitamin D level abnormality in these patients might play a role.

Therefore, the researchers conducted the current systematic review analysis to explore potential associations of vitamin D level with the occurrence as well as the recurrence of BPPV disease.

How the Review Was Done

A comprehensive literature search was conducted using different databases to retrieve all of the articles that have evaluated possible associations, irrespective of the study design.

Then, the researchers reported different vitamin D3 levels from BPPV groups and control groups to estimate the standardized mean difference (SMD) between the BPPV and control groups.

The researchers also calculated the effect size of each study under the random effects statistical model.

What Was Measured

The subject headings attached to it are Benign Paroxysmal Positional Vertigo, Recurrence and Vitamin D Deficiency.

Author keywords: Benign positional paroxysmal vertigo, Meta-analysis and Systematic review.
