Abstract: BACKGROUND:Benign paroxysmal positional vertigo (BPPV) has a reported recurrence ranging from 26.8 to 50%. Osteoporosis and Vitamin D deficiency seems to have an impact on recurrence of BPPV. OBJECTIVE:to evaluate the impact of osteoporosis and Vitamin D deficiency on recurrence of BPPV. METHODS:73 consecutive patients were divided in two groups according to the presence (group 1) or absence (group 0) of a recurrent episode. BMD, femoral and lumbar T-scores and Vitamin D levels were recorded. Statistical analysis was performed to investigate correlations. RESULTS:patients in group 1 had statistically significant lower values of both femoral (–1,62±1,06 vs. –0,53±1,51; p = 0,001), lumbar T-score (–2,10±1,19 vs –0, 53±1.51, p = 0.001) and Vitamin D (19.53±15.33). The values of femoral T-score and Vitamin D could be combined in a model able to properly classify 65.8% of the cases (p = 0.002) as isolated or recurrent BPPV, with high accuracy (AUC 0.710 [0.590 –0.830]). CONCLUSION:present data show a probable correlation between osteoporosis and Vitamin D with recurrent BPPV.
