目的 :探讨孕早期绒毛巨细胞病毒 (CMV)感染与输卵管妊娠的关系。方法 :采用套式聚合酶链反应技术检测 68例输卵管妊娠者和 43例人工流产者的妊娠组织物中的CMVDNA ,比较两组CMV感染率的差异。结果 :输卵管妊娠组中CMVDNA阳性率为 38 2 4 % ,明显高于人工流产组 (P <0 0 5)。结论 :孕早期绒毛CMV感染与输卵管妊娠密切相关 ,可能是引起输卵管妊娠的重要致病因子 ,应作为输卵管妊娠的致病病原体检测项目之一
Objective: To investigate the relationship between CMV infection and tubal pregnancy in early pregnancy. Methods: CMVDNA was detected by nested polymerase chain reaction in 68 pregnant women with tubal pregnancy and 43 cases of induced abortion. The difference of CMV infection rates was compared between the two groups. Results: The positive rate of CMVDNA in tubal pregnancy group was 38.2%, significantly higher than that of induced abortion group (P <0.05). Conclusion: CMV infection during early pregnancy is closely related to tubal pregnancy and may be an important causative agent of tubal pregnancy, and should be used as one of the causative pathogens of tubal pregnancy
