目的系统评价视网膜静脉阻塞(RVO)的危险因素以对其进行有效的预防和治疗。
方法检索Cochrane图书馆、PubMed数据库、Embase数据库。文献检索起止时间均从建库至2018年12月,收集有关RVO危险因素的研究报道。采用NOS评价方法评价文献质量,提取有效数据后,采用Stata 12.0软件进行Meta分析。
结果共纳入31篇文献,其中病例组4 370例,对照组6 534例。Meta分析结果显示,高血压[优势比(OR)=3.08,95%置信区间(CI):2.22~4.28]、糖尿病(OR=1.61,95% CI:1.11~2.32)、高脂血症(OR=1.73,95% CI:1.27~2.36)、高水平脂蛋白A(OR=2.72,95% CI:1.06~6.97)、高同型半胱氨酸血症(OR=1.86,95% CI:1.47~2.35)、凝血因子V Leiden基因突变(OR=1.89,95% CI:1.17~3.06)是RVO发病的风险因素,而亚甲基四氢叶酸还原酶基因(MTHFR)C677T突变(OR=1.41,95% CI:0.93~2.14)、凝血酶原基因G20210A突变(OR=1.20,95% CI:0.81~1.79)非RVO发病的风险因素。亚组分析显示,高血压及糖尿病因素异质性在年龄≥60岁的人群中,分别从88.9%、75.7%降至59.8%、63.2%,高同型半胱氨酸血症因素异质性在年龄<60岁人群中从85.6%降至64.3%。敏感性分析结果显示,改变分析模型后分析结果无明显改变。所纳入研究的文献间均无发表偏倚。
结论高血压、高脂血症、糖尿病、高水平脂蛋白a、高同型半胱氨酸血症、凝血因子V Leiden基因突变是RVO发生的危险因素。
ObjectiveTo evaluate the risk factors for retinal vein occlusion(RVO) through a meta-analysis.
MethodsThe literatures on risk factors of RVO were searched in the Cochrane library, PubMed, and Embase databases.The literature search time ranged from the establishment of database to December 2018.The literatures were evaluated and filtrated by using Newcastle-Ottawa Scale, Stata software (version 12.0) was used for data processing.
ResultsA total of 31 case-control studies with 4 370 cases and 6 534 controls were included.The meta-analysis showed that hypertension (odds ratio[OR]=3.08, 95% confidence interval [CI]: 2.22-4.28), diabetes (OR=1.61, 95% CI: 1.11-2.32), hyperlipidemia (OR=1.73, 95% CI: 1.27-2.36), hyperlipoprotein (a)-emia (OR=2.72, 95% CI: 1.06-6.97), hyperhomocysteinemia (OR=1.86, 95% CI: 1.47-2.35), mutation of coagulation factor V Leiden gene (OR=1.89, 95% CI: 1.17-3.06) were risk factors for RVO.However, mutation of gene MTHFR C677T (OR=1.41, 95% CI: 0.93-2.14)、mutation of prothrombin gene G20210A (OR=1.20, 95% CI: 0.81-1.79) were not found to be risk factors for RVO.Subgroup analysis showed that the heterogeneity of hypertension and diabetes among people aged over 60 decreased from 88.9% and 75.7% to 59.8% and 63.2%, respectively.The heterogeneity of hyperhomocysteinemia in people aged below 60 decreased from 85.6% to 64.3%.The sensitivity analysis results showed that there were no significant differences after changing the analysis model.There was no publication bias among the literatures.
ConclusionsHypertension, diabetes, hyperlipidemia, hyperhomocysteinemia, hyperlipoprotein (a)-emia, mutation of coagulation factor V Leiden gene are risk factors for retinal vein occlusion.
