ABSTRACT
Objectives: The role of uric acid in pathogenesis of benign paroxysmal positional vertigo (BPPV) is not fully understood. It is aimed to assess the serum uric acid levels in BPPV patients compared to healthy controls. Study design: Systematic review and meta-analysis. Methods: Web of science, PubMed, Scopus, Google Scholar, Embase, Medline, and Cochrane library were systematically searched. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) and Problem/Population, Intervention, Comparison, and Outcome (PICO) guidelines were used. Results: In total, 20 studies including 3967 participants met the inclusion criteria. Ten studies (50%) reported higher uric acid (UA) levels in BPPV patients, 4 studies (20%) indicated lower UA levels in BPPV patients, while 6 studies (30%) found no significant difference in UA levels between BPPV patients and healthy controls. The overall mean serum levels of UA (SMD: 0.265, [-0.163 to 0.693]) were higher in BPPV patients than control group. However, this difference was not statistically significant (P-value: .225). Conclusion: There is no significant difference in serum level of UA between BPPV patients and healthy controls. It means that serum level of UA (whether low or high) is not likely the underlying factor of development of BPPV.
