Epstein-Barr virus DNA load in cerebrospinal fluid and plasma of patients with AIDS-related lymphoma.
Detection of Epstein-Barr virus (EBV) DNA in the cerebrospinal fluid (CSF) is associated with acquired immunodeficiency syndrome (AIDS)-related brain lymphoma. Real-time polymerase chain reaction (PCR) was performed to quantify EBV DNA in CSF and plasma from 42 patients with AIDS-related non-Hodgkin's lymphoma (NHL). Twenty patients had primary central nervous system lymphoma (PCNSL) and 22 systemic NHL, including 12 with central nervous system involvement (CNS-NHL). As controls, 16 HIV-infected patients with other CNS disorders were examined. EBV DNA was detected in the CSF from 16/20 (80%) patients with PCNSL, 7/22 (32%) with systemic NHL, 8/12 (67%) with CNS-NHL, and 2/16 (13%) of the controls. The viral EBV DNA levels were significantly higher in the CSF from patients with PCNSL or CNS-NHL compared to patients with systemic NHL or controls. EBV DNA was detected in plasma from 5/16 (31%) patients with PCNSL, 9/16 (56%) with systemic NHL, 4/9 (44%) with CNS-NHL, and 4/15 (27%) controls. No difference in plasma viral load was found between patient groups. From the patients with CNS-NHL, plasma samples drawn prior to CNS involvement contained significantly higher EBV DNA levels than those from systemic NHL patients without subsequent CNS involvement. EBV DNA levels in the CSF, but not in plasma, from patients treated with antiherpes drugs were significantly lower than in untreated patients. High CSF EBV DNA levels were found in HIV-associated brain lymphomas and the viral load can be clinically useful. High plasma EBV DNA levels might predict CNS involvement in systemic NHL.
