title: Human herpesvirus-6 (HHV-6, HBLV) in sarcoidosis and lymphoproliferative disorders.
abstract: Serologic studies were done to estimate the antibody prevalence against human herpesvirus 6 (HHV-6) in patients with malignant lymphomas, Sjögren's syndrome and sarcoidosis. Serologic studies showed IgG antibody titers against HHV-6 in up to 41% of patients with sarcoidosis, 50-70% with malignant lymphomas and in 36% with Sjögren's syndrome. In situ hybridization on lymph node biopsies was positive for HHV-6 genome in 1 out of 5 sarcoidosis lymph nodes.
