 AB    OBJECTIVE: Epstein-Barr virus (EBV) is often associated with HIV
       infection and seems to play a pathogenic role on AIDS-related primary
       lymphomas of the central nervous system (CNS); in fact EBV virus has
       been detected in both brain tissue by in situ hybriditation and
       cerebrospinal fluid (CSF) by polymerase chain reaction (PCR) in HIV
       patients affected by primary CNS limphoma. It has been shown that there
       are two EBV strains, type A and B, but until now neither type seems to
       have a specific disease association. METHODS: We performed PCR to detect
       type A and B EBV-DNA using different sets of specific primers on CSFs of
       five AIDS patients with primary CNS lymphoma. We tested previously these
       CSFs for EBV-DNA by a nested PCR using other primers. RESULTS: All 5
       patients affected by primary CNS lymphoma were positive for EBV-DNA;
       four out of 5 showed positivity for type A EBV-DNA and 1 for type B.
       DISCUSSION AND CONCLUSIONS: We noted a high prevalence of type A EBV-DNA
       in primary CNS limphomas; that could be due to geographical distribution
       but we think that there is a possibility that type A EBV could be more
       strictly associated with primary CNS limphomas than type B. Further
       studies will be required to establish if there is a difference of
       prevalence between type A and B EBV in other lymphoproliferative
       diseases in HIV patients.
