文摘目的探讨绝经女性良性阵发性位置性眩晕(benign paroxysmal positional vertigo,BPPV)患者血清25-羟维生素D_(3)[25-hydroxyvitamin D_(3),25(OH)D_(3)]、血钙水平与骨代谢指标的变化及临床意义。方法选取2020年8月至2021年8月杭州市第九人民医院103例绝经BPPV患者纳入BPPV组,根据1年复发情况,再将其分为复发组(n=18)与无复发组(n=85);另选取同期50名健康体检的绝经女性纳入对照组。收集其临床资料及血清25(OH)D_(3)、血钙、骨代谢指标[Ⅰ型前胶原氨基端前肽(procollagen typeⅠN-terminal propeptide,PINP)、骨钙素N端中分子片段(N-terminal midfragment of osteocalcin,N-MID)、Ⅰ型胶原羟基端肽β降解产物(β-isomerised C-terminal telopeptide of collagen typeⅠ,β-CTX)和骨性碱性磷酸酶(bone alkaline phosphatase,BALP)],构建Logistic回归模型分析绝经女性发生BPPV的危险因素,并采用受试者操作特征曲线分析相关指标对BPPV复发的预测价值。结果BPPV组患者的血清25(OH)D_(3)水平显著低于对照组(P<0.05),长期饮食不规律占比、PINP、N-MID、BALP水平均显著高于对照组(P<0.05);多因素Logistic回归分析结果显示,低25(OH)D_(3)、高PINP、高N-MID、高BALP均是绝经女性发生BPPV的危险因素(P<0.05);复发组患者的25(OH)D_(3)水平显著低于无复发组(P<0.05),PINP、N-MID、BALP水平均显著高于无复发组(P<0.05);25(OH)D_(3)、PINP、N-MID、BALP及四项联合预测BPPV复发的曲线下面积(area under the curve,AUC)分别为0.833、0.654、0.697、0.782、0.910,四项联合预测的AUC最大,敏感度和特异性分别为98.97%、70.62%。结论绝经女性BPPV患者血钙水平无明显改变,血清25(OH)D_(3)水平降低,PINP、N-MID与BALP水平升高均是发生BPPV的危险因素,且可用于BPPV复发的预测。
