Summary An antibody capture assay using an enzyme-linked human cytomegalovirus (HCMV) antigen for the detection of specific immunoglobulin E (IgE) was established. IgG, M, and E responses to HCMV were studied in 497 sera obtained from 44 renal transplant recipients and 51 acquired immunodeficiency syndrome (AIDS) patients. The results were compared with those obtained from 58 HCMV-seropositive healthy individuals. HCMV-specific IgE was detected in 11 (91.7%) renal transplant recipients with primary HCMV infection. In contrast, antibodies of the IgG and IgM classes were detected in only 6 (50.0%) of these patients. Specific IgE was detected in 10 (90.9%) out of 11 renal allograft recipients suffering from secondary HCMV infection. Significant IgG titer rises and IgM were detected in 2 (18.2%) and 6 (54.6%) of these patients, respectively. IgG titer rises and IgM and IgE antibodies were seen in 5 (12.2%), 1 (2.4%) and 18 (43.9%) AIDS patients respectively. All healthy immunocompetent HCMV-seropositive individuals were tested IgE negative. The results obtained in our study indicate that IgE against HCMV is a more reliable serologic marker for primary and secondary HCMV infection than IgM in immunocompromised individuals, especially in organ transplant recipients, since it is not affected by the prophylactic application of HCMV hyperimmune globulin preparations.
