Investigation of viral pathogens contributing to habitual abortion / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the association of Coxsackie B virus (CBV) with habitual abortion.</p><p><b>METHODS</b>CBV IgM antibody, viral RNA and virions were detected in 86 women with habitual abortion and 40 with induced abortion by means of enzyme-linked immunosorbent assay (ELISA), RT-PCR and virus isolation, respectively.</p><p><b>RESULTS</b>The positivity rate of CBV IgM were 87.2% and 35% in the two groups, respectively, and the detection rate of the viral RNA was 53.5% and 17.5% in blood lymphocytes, and 59.3% and 17.5% in the placentas. The virions were found in the placentas in 41.9% and 6.9% of the women, respectively. The positivity rates of CBV IgM, viral DNA and virions showed significant difference between the two groups (P<0. 01).</p><p><b>CONCLUSION</b>CBV might be one of the causes responsible for habitual abortion.</p>
