Objective: To evaluate pregnancy outcome and rate of vertical transmission in primary maternal periconceptional cytomegalovirus (CMV) infection. Methods: All women serologically diagnosed with primary periconceptional CMV infection between 1999 and 2008 were included. Periconceptional infection was defined as primary maternal CMV infection occurring within 4 weeks prior to the last reported menstrual period and up to 3 weeks following the expected date of the missed menstrual period. Intrauterine infection was verified by PCR and shell vial culture of amniotic fluid at 22-24 weeks or neonatal urine culture within 48 h of birth. Results: Of the 59 patients studied, 43 (73%) underwent diagnostic amniocentesis. Eleven of the 43 patients (25.5%) were positive for CMV contamination. Ten of the 11 patients (90%) elected to terminate pregnancy. Twelve women (20.3%) declined amniocentesis: of these 2 elected to undergo a first-trimester termination of pregnancy and 10 gave birth to a live-born infant. Six of the ten neonates were negative for CMV and two tested positive for urinary CMV; all eight were healthy on long-term follow-up, and two were lost to follow-up. The remaining four women had a spontaneous first-trimester abortion. Conclusion: The risk of transmission of periconceptional CMV infection is lower than previously reported. These data should be borne in mind when counseling affected couples.
