Abstract
OBJECTIVES: This study was undertaken to ascertain the acquisition of cytomegalovirus infection following exchange transfusion and factors affecting such transmission in newborn infants at a tertiary care hospital in India. METHODS: Neonates undergoing double volume exchange transfusion (for any indication) with whole blood in the Neonatal Intensive Care Unit were enrolled over a 8 month period. Serum samples from the infant were collected for CMV serology before exchange transfusion, and at 6 and 12 weeks following the exchange. CMV serology was also conducted on samples obtained from the respective maternal and donor blood. RESULTS: Of 47 neonates who received exchange transfusion during the study period; only 26 (55.3%) neonates were finally followed up till 12 weeks of age. Only 3 (11.5%) children demonstrated CMV seroconversion during follow-up; all were low birth weight and small for gestational age. None of them demonstrated any clinical, hematological, biochemical, or radiological signs suggestive of perinatal CMV infection either at birth or during the course of follow-up. CONCLUSION: Exchange transfusion in neonates can result in perinatal transmission of CMV infection in low birth weight neonates. Such transmission does not result in any immediate manifestations. Data are not sufficient to warrant routine CMV screening of donor blood for exchange transfusion in our setting.
