Objective:To investigate the expression level of serum 25-（OH） D and its correlation in patients with vestibular neuritis（VN）. Methods:30 acute VN patients and 50 age-and sex-matched healthy controls who attended the Otolaryngology, Head and Neck Surgery Department of the First Hospital of Shanxi Medical University from October 2020 to October 2021 were selected. The demographic and clinical data of all subjects were recorded, the levels of serum 25-（OH） D and inflammatory markers were measured and compared, and the changes of serum 25-（OH） D levels in convalescent patients with VN were followed up. Results:The serum level of 25-（OH） D in the acute phase VN group was significantly lower than that in healthy controls[（10.14±2.92） ng/mL vs （20.61±4.70） ng/mL, P<0.01], and the deficiency rate of 100.0%（30/30） was significantly higher than 54.0%（27/50）. Moreover, the serum level of 25-（OH） D in the recovery period（3 months later） was significantly higher[（10.14±2.92） ng/mL vs （15.94±4.88） ng/mL, P<0.01], and the deficiency rate was significantly decreased by 76.7%（23/30）. However, the serum 25-（OH） D level was significantly lower in both the VN group than that in both the acute period and the recovery group, and the deficiency rate was significantly higher than that in the control group. Multivariate binary Logistic regression model analysis showed that low-level serum 25-（OH） D was associated with the onset of VN, with an OR value of 0.193（95%CI=0.043-0.861, P=0.031）. In addition, the results of this study showed that peripheral blood leukocyte（WBC） and neutrophil / lymphocyte ratio（NLR） levels in the acute VN group were significantly higher than in healthy controls[（7.65±3.02） ×10⁸/L vs （5.50±2.50） ×10⁸/L, P<0.01; （2.46±2.95） ×100% vs（1.67±0.92） ×100%, P<0.01 ], and there was no significant difference in Platelet / lymphocyte ratio（PLR） and and average platelet volume（MPV） levels in the two groups（P>0.05）. There were no significant differences in age distribution, sex ratio, body mass index, persistent health problems, or lifestyle groups（P>0.05）. Conclusion:This study is the first to detect serum 25-（OH） D level and inflammation index level, and dynamically assess the serum 25-（OH） D level in different stages, found that low serum 25-（OH） D is associated with the onset of VN, physiological concentration of serum 25-（OH） D is a protective factor of VN, vitamin D supplementation therapy may be a new target of VN treatment.
目的：探讨前庭神经炎（VN）患者血清25-羟维生素D[25-（OH）D]的表达水平及其相关性。 方法：选取2020年10月-2021年10月在山西医科大学第一医院耳鼻咽喉头颈外科就诊的符合纳入、排除标准的30例急性期VN患者和50例年龄、性别匹配的健康对照者。记录所有受试者的人口统计学数据和临床数据，测量和比较血清25-（OH）D水平和炎症指标水平，并追踪VN患者恢复期（3个月后）血清25-（OH）D水平的变化情况。 结果：急性期VN组的血清25-（OH）D水平明显低于健康对照组[（10.14±2.92） ng/mL和（20.61±4.70） ng/mL，P<0.01]，缺乏率100.0%（30/30）明显高于对照组54.0%（27/50）。且VN患者恢复期（3个月后）血清25-（OH）D水平较急性期明显升高[（10.14±2.92） ng/mL和（15.94±4.88） ng/mL，P<0.01]，缺乏率76.7%（23/30）明显降低。但无论是急性期还是恢复期，VN组的血清25-（OH）D水平均明显低于对照组，缺乏率均明显高于对照组。多因素二元logistic回归模型分析显示低水平血清25-（OH）D与VN的发病相关，OR值为0.193（95%CI=0.043～0.861，P=0.031）。此外，本研究结果显示急性期VN组的外周血白细胞（WBC）和中性粒细胞/淋巴细胞比率（NLR）水平均明显高于对照组[（7.65±3.02）×10⁸/L和（5.50±2.50）×10⁸/L，P<0.01；（2.46±2.95）×100%和（1.67±0.92）×100%，P<0.01）]，两组的血小板/淋巴细胞比率（PLR）和血小板平均体积（MPV）水平差异无统计学意义（P>0.05）。两组的年龄分布、性别比、体重指数、持续健康问题或生活方式方面差异均无统计学意义（P>0.05）。 结论：本研究首次对急性期VN患者进行血清25-（OH）D水平和炎症指标水平的同步检测，并动态评估VN患者不同阶段的血清25-（OH）D水平，发现低水平血清25-（OH）D与VN的发病相关，生理浓度下的血清25-（OH）D是VN的保护性因素，维生素D补充治疗可能成为VN治疗的新靶点。.
