良性特发性眼睑痉挛的发病危险因素分析

目的 探讨良性特发性眼睑痉挛(benign essential blepharospasm,BEB)发病的危险因素以及各因素的作用强度.方法 病例组为2009年4月至2010年3月在中国医学科学院北京协和医院神经内科门诊就诊的BEB患者100例,可合并相邻部位的肌张力障碍.对照组来自同期神经科门诊就诊的偏侧面肌痉挛(hemifacial spasm,HFS)患者100例以及健康对照40名,男女比例与病例组匹配,无锥体外系及其他神经系统疾病.对所有研究对象进行问卷调查,包括一般情况、社会行为因素、环境因素、精神因素、遗传因素、既往病史.数据录入SPSS 11.0软件进行Logistic回归分析.结果 多因素回归分析显示,眼病(OR=5.818,95% CI 2.510～13.486)、焦虑(OR=3.433,95% CI 1.548～7.610)、抑郁(OR=2.894,95% CI 1.091～7.681)与BEB呈显著正相关,饮用咖啡(OR=0.251,95% CI 0.080～0.784)与BEB呈显著负相关(均P＜0.05).结论 眼疾、焦虑、抑郁可能是BEB发病的独立危险因素;一过性意识障碍的头面部外伤史与BEB有一定的相关性;咖啡饮用史可能是BEB的保护因素.局部损伤及精神因素作为BEB发病的危险因素可能比遗传因素更重要.

Abstract：

Objective To explore the risk factors of benign essential blepharospasm( BEB) and each factor' s intensity.Methods Totally 100 patients with BEB including Meige and cranial-cervical without other neurological abnormalities were recuited from the outpatient clinic of Department of Neurology, Peking Union Medical College Hospital from April 2009 to March 2010 as case group.At the same time, 100 outpatients diagnosed with idiopathic hemifacial spasm ( HFS) and 40 healthy controls without extrapyramidal diseases or other neurological diseases were recuited from the same outpatient clinic.All the cases and controls were investigated by questionnaires about general conditions, social behavioral factors, environmental factors, phychiatrical factors, genetic factors, previous diseases.The data was analysed by Logistic regression model with the statistical software SPSS 11.0.Results Multivariate analysis indicated that eye disease (OR = 5.818, 95% CI 2.510-13.486), anxiety (OR=3.433, 95% CI 1.548-7.610) and depression (OR =2.894, 95% CI 1.091-7.681) were positively related with BEB, whereas coffee drinking (OR = 0.251, 95% CI 0.080-0.784) had a negative relationship with BEB ( all P ＜ 0.05 ).Conclusions The risk factors of BEB are eye diseases, anxiety and depression.Coffee drinking is protective for BEB.The results suggest that local injury and phychiatrical factors may be more important than genetic factor in the aetiology of BEB.
