abstract

  • BACKGROUND: Polymerase chain reaction (PCR) assays of cerebrospinal fluid (CSF) for cytomegalovirus (CMV) DNA have facilitated the diagnosis of CMV-associated central nervous system disease in AIDS patients. We attempt to correlate clinical and radiographic features that are associated with CMV PCR- positivity in CSF from AIDS patients with neurologic disease. METHODS AND RESULTS: A retrospective case controlled comparison was made of CMV PCR-positive and PCR-negative patients. RESULTS: CMV PCR-positive patients were significantly more likely to have nystagmus, prior CMV retinitis, and CSF protein levels.90 mg/dL. Of patients with 0, 1, and $2 of these features, 5.6%, 55.2%, and 88.9%, respectively, were PCR-positive. Ependymal enhancement was present by magnetic resonance imaging in 9 of 12 PCR-positive, and in 8 of 30 PCR-negative patients. CONCLUSION: These clinical and radiographic features may serve as useful adjuncts toward the establishment of the diagnosis of CMV-associated neurologic disease in AIDS patients.
