title: [Sequences of human herpes virus type 8 and Epstein-Barr virus in AIDS-related primary central nervous system non-Hodgkin's lymphoma].
abstract: Presence of human herpes virus type 8 (HHV8), detected by nested PCR, and expression of Epstein-Barr virus (EBV), as assessed by immunochemistry and in situ hybridization, were evaluated in 20 primary non-Hodgkin immunoblastic lymphomas (NHL) of the central nervous system (CNS) from patients who died from AIDS, and in 10 samples of cerebral tissues from patients who died from AIDS, without cerebral lymphoma or Kaposi's sarcoma, as controls. Six lymphomas (30%) contained HHV8 sequences, and 19 (95%) expressed EBV; detection of HHV8 was more frequent in patients with Kaposi's sarcoma, than in other subjects (4/6 versus 2/14). Three (30%) controls contained HHV8 sequences, whereas none expressed EBV. AIDS-related CNS NHL is therefore clearly associated with EBV expression, while the presence of HHV8 appears occasional, probably associated with a low tissue viral load. The high frequency of HHV8 in AIDS-related primary CNS NHL patients with Kaposi's sarcoma suggests that this virus could play a role in the pathogenesis of some cerebral lymphomas.
