摘要
Objective:To evaluate changes in calcium metabolism in patients with idiopathic benign paroxysmal positional vertigo (BPPV) on initial presentation and at the follow-up visit.Subjects and Methods:The study comprised a total of 31 patients aged greater than 18 years who presented at the otorhinolaryngology outpatient clinic of our hospital, newly diagnosed as idiopathic BPPV based on the history compatible with BPPV and positive provocative maneuver (either Dix-Hallpike or Roll test). The first blood sample was obtained on the day of initial presentation when the patient was found to have active unilateral BPPV. After 6 months, a blood sample was again drawn in accordance with the procedure. Blood samples were analyzed for data on 25-hydroxyvitamin D (25(OH)-D), total calcium, parathormone and ionized calcium on initial presentation, and at the follow-up visit.Results:The patients comprised 20 (64.5%) women and 11 (35.5%) men with a mean age of 49.78 years (range, 23-75 years). During an attack a higher prevalence of decreased serum Vitamin D is less than 20ng/ml, was determined (93.5% versus 38.7%). There were statistical differences between the Vitamin D values, parathormone, and corrected by pH ionized calcium in both periods (p<0.05).Conclusion:A statistically significant association was determined between Vitamin D and calcium metabolism in patients with idiopathic BPPV. It can be considered that Vitamin D deficiency and decreased ionized Ca level may be a risk for BPPV, not only in patients with osteoporosis but also in all patients. Very low levels of 25(OH)-D seem to be associated with recurrence of BPPV. The recurrences might possibly be prevented with supplementary Vitamin D especially in those with recurrent idiopathic BPPV but further studies would be necessary to determine this.
