METHODS: A retrospective study was conducted on 115 pregnancies with CMV primary infection. A total of 111 AF and 106 FB samples were investigated for various virological and non-virological markers. Detailed ultrasound examinations were performed at time of PD. RESULTS: Overall sensitivity of CMV PCR in FB (75.6%; 95%CI 60-87) and AF (72.7%; 95%CI 57-85) was comparable. In women with amniocentesis textgreater8 weeks between seroconversion and PD, we did not observe significant differences between amniocentesis performed textgreater/=17 + 0 (sensitivity 90.9%; 95%CI 71-99) and textgreater/=20 + 0 gestational weeks (sensitivity 90.0%; 95%CI 68-99).

However, platelet counts textless120 x 10e9/L and beta-2 microglobulin values textgreater14 mg/L were more frequently found in fetuses with severe ultrasound abnormalities compared with fetuses with no or mild abnormalities (p textless 0.001). CONCLUSION: Optimal timing of amniocentesis in women with primary infection in early gestation should be reevaluated in a prospective study. Analysis of FB markers may be beneficial in the individual management of pregnant women with confirmed congenital CMV infection.
