Cytomegalovirus (CMV) Infection in Pregnancy
Cytomegalovirus Infection and Pregnancy Outcomes

The purpose of this study is to determine if (recurrent) cytomegalovirus (CMV) infection of the mother results in pregnancy complications such as preterm delivery, severe preeclampsia, poor fetal growth, or stillbirth.

CMV infection in adults with a normal immune system is rarely a serious event. Once a person has been infected with CMV, they may have recurrences (relapses) of the infection. If a mother is infected with the virus or relapses during pregnancy, her fetus may be at risk for infection. Unlike infection in adults, fetal infection may result in serious complications (congenital infection). The effects of fetal infection with CMV are well understood and many efforts have been made to potentially reduce the risk of congenital infection. However, the effect of CMV infection on the pregnancy itself (when the fetus is not affected by CMV) is less understood.

In this study, we plan to determine if CMV recurrence in the mother results in pregnancy complications. The pregnancy complications listed above have been associated with poor placental function. We also plan to determine if (recurrent) CMV infection in the mother is associated with CMV infection of the placenta.
