title: A serological study of cytomegalovirus infection in pregnant and non-pregnant women at Gauhati Medical College and Hospital.
abstract: Primary cytomegalovirus infection is the most common infection during pregnancy that may have long-term neurodevelopmental sequelae in children born to these mothers. It is also associated with many obstetric complications. So the aim of this study was to determine the seroprevalence of cytomegalovirus infection in local antenatal population with bad obstetric history and to see the effects, if any, of age, socio-economic status, presenting features and different gestational periods. Seventy-five pregnant women with bad obstetric history were screened for the presence of cytomegalovirus specific IgM and IgG antibodies by doing enzyme-linked immunosorbent assay, out of which 17(22.66%) had evidence of recurrent cytomegalovirus infection as demonstrated by the presence of cytomegalovirus specific IgM antibodies. All were found to be positive for cytomegalovirus specific IgG antibodies. This indicates that the presence of cytomegalovirus specific IgM antibodies in this population is an evidence of reactivation of a latent infection or re-infection with a different strain of cytomegalovirus. Increased IgM seropositivity was found to be associated with advancing age, poor, socio-economic status, third trimester of pregnancy and bad obstetric history like premature delivery, stillbirth, recurrent spontaneous abortions, intra-uterine growth retardation. Out of 25 randomly selected non-pregnant women of childbearing age, all showed presence of cytomegalovirus specific IgG antibodies and none was found to be positive for primary or recurrent cytomegalovirus infection.
