Objective: To investigate whether cytomegalovirus (CMV) infection might be associated with vertical transmission of it. To assess the possible role of CMV infection in early pregnancy failure (missed miscarriages). Methods: Subjects include normal pregnancies and missed miscarriages at early gestation undergoing dilatation and curettage (D&C). All the subjects were given the measurements of serum anti-CMV antibodies by a chemiluminescent microparticle immunoassay and CMV-DNA detection in blood, urine and cervical secretion by real time PCR. There were 63 subjects with positive CMV-DNA in cervical secretion. According to positive to negative CMV DNA (in cervical secretion) ratio of 2:1, 38 subjects with negative CMV-DNA in cervical secretion were selected randomly. The 101 subjects received CMV DNA test in placental villi/ deciduas during D&C. Results: Anti-CMV IgG seroprevalence were found in 100.0% (63 cases) with 1.6% of IgM positive case (1 case) in the 63 women with positive CMV-DNA in cervical secretion. In the 38 women with negative CMV-DNA in cervical secretion, anti- CMV IgG seroprevalence were found in 92.1% (35 cases) without IgM positive case. CMV-DNA in blood was negative in all 101 subjects. Positive CMV-DNA in placental villi/ deciduas was present in 5 cases (7.9%; 2 normal pregnancies and 3 missed miscarriages) of women with positive CMV-DNA in cervical secretion. No case of negative CMV-DNA in cervical secretion was found with positive CMV-DNA in placental villi/ deciduas. The rate of missed miscarriages was 52.4% (33/63) and 42.1% (16/38) in women with positive and negative HCMV DNA in cervical secretion respectively, and the difference was not statistically significant (P>0.05). Conclusions: CMV replication in cervical secretion may reflect a uterine CMV infection, involve in CMV vertical transmission, but not increase the risk of missed miscarriage in women with early pregnancy.
