Abstract
Antibodies against cytomegalovirus-specific early antigens (CMV-EA) were followed in sera, obtained from fifteen immunosuppressed renal-allograft recipients. Eight patients (sixty-two sera) showed seroconversion 47--137 days post-transplantation. Five patients (forty sera) with CMV antibodies at the moment of renal implantation all showed CMV-EA antibody rises. Two patients remained seronegative until 4 years after transplantation. Thus, in immunosuppressed patients, antibodies against CMV-EA remained a high titres during many years (4--8 years) after transplantation as distinct from the apparently transient nature in acutely infected previously healthy adults with CMV mononucleosis or post-perfusion syndrome. These results support the view that CMV-EA antibodies reflect an active viral proliferation in the host.
