Antibody responses against lytic and latent Kaposi sarcoma (KS)-associated herpesvirus antigens were investigated in patients with KS, multicentric Castleman disease (MCD), and primary effusion lymphoma. Antibodies against the lytic antigen K8.1 were 5-fold higher in patients with MCD than those with KS, whereas antibodies to the sum of latent antigens v-cyclin and LANA were 27-fold higher in patients with KS, compared with patients with MCD (P< .001). The sum of anti-v-cyclin and anti-LANA antibody titers discriminated patients with KS from those with MCD and KS with 93% sensitivity and 83% specificity. These results suggest that antibody responses to lytic and latent KS-assodated herpesvirus antigens differ in these diseases.
