Early detection of primary cytomegalovirus infection after heart and kidney transplantation and the influence of hyperimmune globulin prophylaxis.

A randomized study of prophylaxis with hyperimmune globulin (HIg) was performed in 28 cytomegalovirus (CMV)-seronegative heart and kidney recipients with CMV-seropositive donors who were extensively monitored for active CMV infection and CMV disease. Detection of CMV antigen in peripheral blood granulocytes (antigenemia) was the first sign of primary CMV infection, generally occurring several weeks before IgM or IgG anti-CMV antibodies were detected and before positive cultures appeared. A correlation was found between rejection treatment with OKT3 or ATG, severity of CMV disease, and graft loss. Rejection treatment had no influence on incidence of CMV transmission. Primary CMV infection occurred most often in older patients with older donors. No beneficial effects were seen with HIg prophylaxis, which was administered from week 1 until week 7 after transplantation. Incidence of primary CMV infection was equal in both groups (50%) and no influence on the severity of primary CMV infection was seen. The only effect that was seen was on the time from transplantation to detection of active CMV infection, which was prolonged by HIg prophylaxis.
