Lymphocyte responses to EBV-associated antigens in infectious mononucleosis, and Hodgkin's and non-Hodgkin's lymphoma patients, with the leukocyte adherence inhibition assay.
The leukocyte adherence inhibition (LAI) assay was utilized as a test for cellular immunity to Epstein-Barr virus (EBV) antigens in 22 patients with infectious mononucleosis (IM), 47 patients with lymphoma, 101 carcinoma patients, and 84 subjects without cancer. Response to EB virion ("v") antigen was generally present at the time of diagnosis in the IM patients but the response to EB soluble ("S") antigen was delayed. An increased CMI response to "v" antigen was found in patients with IM, Hodgkin's disease and non-Hodgkin's lymphoma as compared to controls with and without cancer. Patients with Hodgkin's disease had depressed responses to the EBV-associated "S" antigen. The finding of increased LAI responses to "v" antigen in Hodgkin's disease patients with high EBV antibody titers conflicts with previous reports attributing high antibody responses against EBV to a generalized depressed cell-mediated immunity.
