导致不良妊娠的多病原体因素检测分析及临床意义

目的 探讨B19V等10种病原体感染与人类不良妊娠之间关系。方法 采集静脉血液、流产组织和胎盘组织为标本，应用PCR方法检测组织标本各种病原体，应用ELISA检测血液标本相应的IgM的抗体。结果 病原体在不良妊娠组中的分布呈B19V（23．6％）＞CMV（16．0％）＞TOX（15．1％）＞RV（1064％）＞UU（9．4％）＞COX（7．5％）＞HSV（6．6％）＞ADV、EDV（3．8％）＞CT（2．8％）排序。三组间，B19V、CMV、RV、HSV、TOX结果的差异具有显著性（P＝0．000－P＝0．031），其余病原体之间的差异无显著性（P＝0．121－P＝0．724）。结论 病原体感染是导致不良妊娠的重要原因之一，其中B19V、CMV、TOX、RV、HSV可能是主要病原体，其余病原体对导致不良妊娠也有一定的影响。

An Analysis on Detection of Multipathogens Infection in the Women with Unhealthy Pregnancy

Objective　To analysis the relationship between the multipathogens infection and unhealthy pregnancy.Methods　All patients was selectively divided into three groups:group A including 106 patients with unhealthy pregnancy,group B:55 gravidas with normal induced abortion,group C:55 normal parturient with term labor.The ten kinds of pathogens from abortion tissues and placentas were tested by PCR method respectively.Anti-pathogen IgM antibodies were detected by ELISA in the blood specimens.Results　The distribution status of the pathogens were as followed:Human parvovirus B19(B19V 23.6%)＞Cytomegalovirus(CMV,16.0%)＞Toxoplasma (TOX，15.1%)＞Rubella virus(RV，10.4%)＞Ureaplasma urealyticum(9.4%)＞Coxsackie(7.5%)＞Herpes simplex virus(HSV,6.6%)＞Adenovirus,Eprstan Barr virus(3.8%)＞Chlamydia trachomatic(CT 2.8%) in the group A.The positive rates of the pathogens infection in both group C and group B were lower.The positive rates of B19V,CMV,RV,HSV,TOX were significant difference(χ2 test,P＝0.000～P＝0.031) among the three groups,hovever others were not(χ2 test,P＝0.121～P＝0.724).Conclusions　The pathogen infection is an important factor to occur the unhealthy pregnancy,the major pathogens of unhealthy pregnancy are B19V，CMV，TOX，RV，HSV.These pathogens infection should be detected timely in gestational period.
