Abstract:
Objective:To explore the correlation between the expression levels of serum estradiol and otolin-1 and the recurrence of postmenopausal benign paroxysmal positional vertigo (BPPV).Methods:A total of 116 postmenopausal female patients who were diagnosed with primary BPPV in the Vertigo Treatment Center of Beijing Geriatric Hospital from January 2018 to December 2019 were selected as the research objects. They were divided into recurrence group (27 cases) and the non-recurrence group (89 cases) according to the recurrence during follow-up. The basic data, laboratory indexes and complications of the two groups were compared. The serum estradiol level was detected by electrochemiluminescence and the serum otolin-1 level was detected by enzyme-linked immunosorbent assay. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of serum estradiol and otolin-1 in the recurrence of postmenopausal BPPV patients; Multivariate logistic regression was used to analyze the risk factors of recurrence in postmenopausal BPPV patients.Results:The proportion of severe cough in the recurrence group was higher than that in the non-recurrence group ( P<0.05); the level of estradiol in the recurrence group was significantly lower than that in the non-recurrence group ( P<0.05), and the level of otolin-1 was significantly higher ( P<0.05); ROC results showed that the areas under the curve (AUCs) of serum estradiol and otolin-1 for predicting the recurrence of postmenopausal BPPV patients were 0.852 (95% CI: 0.774-0.911) and 0.722 (95% CI: 0.631-0.801) respectively, and the cut-off values were 18.09 pg/ml and 361.79 pg/ml respectively; Multivariate logistic regression analysis showed that severe cough, estradiol ≤18.09 pg/ml, and otolin-1 >361.79 pg/ml were independent risk factors for recurrence in postmenopausal BPPV patients ( P<0.05). Conclusions:The serum estradiol level of patients with postmenopausal BPPV recurrence decreases, and the level of otolin-1 increases. The abnormal level is an independent risk factor affecting the recurrence of patients with postmenopausal BPPV.
