Methods 367 pregnant women in Qinba mountainous area were monitored with ELISA and PCR and presented with questionnaire. We detected the following: CMV DNA in urine of 63 neonates born within two weeks whose mother infected CMV during pregnancy and CMV DNA in breast milk post delivery within two weeks of 61 women infected and 84 women non infected. Results Infection rate of CMV in mental retardation prevalent area was 19.62% , the incidence of transmission in uterus was 33.33%, the incidence of excretion by breast milk was 39.34%, CMV infection during pregnancy relates to age, education, economic states, pregnant frequency and pathological delivery. It has no relation with gestational age. Conclusion The study points out that attention should also be paid to detecting CMV infection during pregnancy in mental retardation prevalence. Less education, worse financial condition, more frequent or pathological delivery should be regarded as high risk factors of CMV infection during pregnancy.展开更多

Among them, 100 cases were positive for IgM (group 1). 69 for both IgM and serous DNA (group 2) and 69 for both IgM and mRNA (group 3). The infectious status, maternal-fetal transmission and pregnancy outcome were monitored. It was demonstrated that the accordance rate of group 3 and group 2 with group 1 was 56. 25 % and 43. 75 % , respectively. The maternal-fetal transmission rate in the group 1, 2 and 3 was 19. 00 % , 40. 58 % and 46. 15 %, respectively, with a significant difference found between group 2, 3 and group 1 (P<0. 01). Incidence of spontaneous abortion, fetal death, fetal abnormality and neonatal death in group 1, 2 and 3 was 10. 00 %, 15. 94 % and 30. 77 %, respectively, and that of group 3, 2 was 4 and 2 times as much as that of group 1, respectively (OR = 4. 00, P<0. 001; OR=2. 343, P<005, respectively). It was concluded that HCMV-IgM(+) can only be considered as an screening indicator for pregnant women with HCMV infection, while IgM(+) combined with serous DNA( + ) or mRNA( + ) indicates active infection and has a high incidence of maternal-fetal transmission and abnormal pregnancy outcome.展开更多

The aim of this study was to explore the presence of psychiatric symptoms, in relation with infection of TORCH agents, specifically the Toxoplasma gondii (T. gondii) and Cytomegalovirus (CMV). The study was conducted on 58 pregnant women recruited from the Clinical Virology Unit, A.O.U. Policlinico-Vittorio Emanuele, P.O. “Gaspare Rodolico”, from September 2012 to March 2014. Psychiatric symptoms were evaluated through the Symptom Checklist-90 Revised (SCL-90 R) in pregnant women with CMV or T. gondii infection. Moreover, pregnant women were invited to participate in a program of “Counseling about behavioral change”, an effective psychotherapeutic training for the development of new motivational strategies to the infection acceptance, the greater self-confidence and greater adherence to treatment. The age of the subjects was positively correlated with Depression (r = 0.119, p ? 0.178, p ? 0.231, r = ? 0.320, p ? 0.208, p ? 0.105, p ? 0.236, p < 0.05). Finally, we can notice an improvement of the variables Anxiety and Somatization in the whole sample after the attendance at the counseling psychotherapic program. Our study suggests the presence of anxiety and somatization in pregnant women with infection, expression of a phase of emotional fragility with the concern of transmitting a serious disease in the unborn child. The program “Counseling about behavioral change” allowed us to create an atmosphere of trust and to understand the usefulness of “empathic listening”. Giving correct and accurate information about the disease reassures the patient and prevents the realization of negative thoughts and further concern and discomfort.展开更多

METHODS: The HCMV late mRNA in peripheral blood of 42 HCMV IgM positive pregnant women and their fetal attachments (such as chorionic villi, amniotic fluid, umbilical blood and placenta) were detected by reverse transcription polymerase chain reaction (RT-PCR). RESULTS: Late mRNA was detected in 23 of 42 HCMV IgM positive cases, a rate of 54.3%. Fetal appendages in 13 cases of late mRNA positive mothers were also tested, of which 7 were positive, with a vertical transmission rate of 53.8%. In 12 late mRNA negative mothers, only 1 case of fetal appendages tested was positive, with a vertical transmission rate of 8.3%. There was significant difference between the transmission rates of these two groups. CONCLUSIONS: Positive results of HCMV IgM cannot accurately reflect the activity of HCMV at the time of testing. However, the activity of HCMV is closely related to the mother-fetus vertical transmission rate. As an indicator of active HCMV infection, late mRNA can not only reflect the mother-fetus transmission rate during active HCMV infection, but also provide some information about HCMV activity in fetal tissue.展开更多
