OBJECTIVE: To determine whether activation of Epstein-Barr virus ( EBV ) replication in tumour cells of AIDS-related non-Hodgkin's lymphoma ( ARNHL ) is correlated with CD4+ cell counts and influences antibody response to EBV [ anti-Z Epstein-Barr replicative activator ( ZEBRA ), anti-early antigen ( EA ), anti-viral capsid antigen ( VCA )].
 protein: anti-early antigen; protein: CD4+; cell type: tumour cells; protein: anti-Z Epstein-Barr replicative activator; protein: ZEBRA; protein: anti-viral capsid antigen; protein: VCA; protein: EA
