THE INCIDENCE AND CONSEQUENCES OF CYTOMEGALOVIRUS TRANSMISSION VIA BLOOD-TRANSFUSION TO LOW-BIRTH-WEIGHT, PREMATURE-INFANTS IN NORTH-EAST SCOTLAND

In a 2-year study involving 133 premature low birth weight (<1,500 g) infants, the impact of CMV infection via blood transfusion was assessed. 8.4% (7 out of 83) of transfused infants and 10% (7 out of 70) of those exposed to seropositive blood acquired CMV In those less than 1,250 g the infection rate rose to 13.2% (7 out of 46). Seropositive infants were at a higher risk of acquiring CMV infection than seronegative ones. CMV infection did not give rise to specific immediate morbidity, and no deaths were attributed to CMV. The only source of nosocomial CMV infection was the transfused seropositive blood. Based on these findings, it was possible to formulate a CMV transfusion policy to premature infants in our region.
