title: [Serologic diagnosis of cytomegalic inclusion disease using the Elisa technic in kidney transplant patients].
abstract: During the first six months after transplantation cytomegalovirus-(CMV-)specific serum IgM and IgG antibody titres were determined regularly with the Elisa technique in 25 renal transplant recipients and compared with results of the complement binding reaction (CBR). Active CMV infection was diagnosed in six patients: two primary infections and four reactivations. Titres of 1 : greater than 40 were considered positive. IgG titre increases of up to 1 : 20 000 and of 1 : 4000 for IgM were observed. IgM titres of 1 : greater than 200 are suspicious of active CMV infection, four-fold titre increases establish the diagnosis. Such IgM titres were accompanied by clinical symptoms of active CMV infection. The Elisa technique is a reliable method from the first week of disease for early demonstration of CMV infection. The prognostically relevant differentiation between primary CMV infection and reactivation of latent disease is possible using the IgG/IgM antibody titre relations. IgM titres indicate cure or persistence of infection. CBR with CMV antigen is of no use for diagnosis.
