Sero-Prevalence of Cytomegalo Virus Antibodies in Pregnant Women Attending Two Selected Hospitals in Sokoto State, North-Western Nigeria

Abstract

Infection with cytomegalo virus (CMV), especially in pregnancy may cause pregnancy complications such as congenital infection, non-hereditary deafness, intrauterine growth restriction and other high defects. This study was to evaluate the prevalence of CMV in pregnant women attending Antenatal Clinics at Maryam Abacha Women and Children Hospital (MAWCH) and Sokoto Specialist Hospital (SSH). The study enrolled 90 pregnant women (age range: 16-45 years old) and data on demographic and life styles obtained using structured questionnaire. Serum samples were assayed using CMV Ig-G EIA kit. Out of the 90 pregnant women examined, 88(97.8%) had IgG protective antibodies to CMV while 2(2.2%) did not have protective antibodies. The prevalence rate of 2.20% was obtained in pregnant women that did not have the protective CMV IgG antibodies and were in the age range of 16-30 years old. They were also found to be in their second trimester, which could have increased the risk of intrauterine transmission. The risk factors for CMV were observed to have been significantly (P > 0.05) correlated with the socioeconomic status, the levels of CMV Ig-G antibodies, stage of pregnancy as well as the symptoms of pregnancy complications observed in the study population while they were insignificant (P < 0.05) in the case of number of previous pregnancies. The outcome of effects on the fetus was usually fatal and irreversible. Therefore, all pregnant women should scrupulously consistently adhere to routine infection control precautions.
