Abstract:
Objective:To investigate the relationship between the recurrence of benign paroxysmal positional vertigo(BPPV) and the levels of bone mineral density(BMD) and estrogen in postmenopausal women.
Methods:A total of 38 postmenopausal women with recurrent BPPV were recruited as study group, in the First Affiliated Hospital of Soochow University from December 2013 to June 2017. Meanwhile, 49 normal menopausal women were included as control. All patients were natural menopausal for over one year.The patients were diagnosed as BPPV based on results of Dix-Hallpike test and Roll-test, with at least two episodes of recurrent onset. In the subjects, BMD was measured by dual X-ray absorptiometry of lumbar vertebrae. Estrogen levels were obtained by testing serum estradiol (E2) levels in early morning fasting venous blood. In the present study, we compared the level of E2 and the value of BMD in two groups by SPSS 21.0. In the study group, patients with decreased BMD were divided into two groups: treatment and untreated group. The recurrence rate of BPPV was compared between the two groups within 12 months.
Results:①The averagel levels of E2 and BMD in the study group were (16.21±11.00)ng/L and -1.68±0.98) respectively, which were significantly lower than those in the control group (t value was 7.03 and 8.05 respectively, both P<0.05). The averagel levels of E2 and BMD incontrol group were(28.52±6.34)ng/L and -0.18±0.77 respectively. ②The number of patients with decreased BMD in the study group (30 cases) was more than that in control group (6 cases), and the difference was statistically significant (P<0.05). ③ The recurrence rate of BPPV in treatment group [17.6%(3/17)] was significantly lower than that of untreated group [61.5%(8/13)], and the difference was statistically significant (P<0.05).
Conclusion:Recurrent BPPV in postmenopausal women usually accompany with low levels of estrogen and BMD. Active treatment is helpful for their recurrence of BPPV.
