Vitamin d influence on the clinical course of benign paroxysmal positional vertigo: A retrospective cohort study

Abstract

Aim and objective: This retrospective cohort study was designed to investigate the possible relationship between vitamin D and the clinical course of benign paroxysmal positional vertigo (BPPV). Materials and methods: The medical records of patients admitted to a tertiary health center between January 2017 and December 2018 were retrospectively reviewed. Ninety idiopathic BPPV and one hundred healthy subjects without vertigo were included in the study. Results: The serum vitamin D concentration and BPPV occurrence were not correlated (p = 0.601). BPPV recurrence was significantly affected by age (p = 0.028) and serum vitamin D concentrations (p = 0.02). Conclusion: This study indicated that there is no causal relationship between low vitamin D levels and BPPV. Another result of the study is that low vitamin D concentrations and older age increase BPPV recurrences. This increase in recurrence due to vitamin D deficiency does not eliminate oral vitamin D treatment. Clinical significance: The relationship between vitamin D and BPPV is still controversial and the effect of vitamin D administration on the BPPV treatment process is unknown. © Jaypee Brothers Medical Publishers.
