title: Nonsteroidal anti-inflammatory agents in the therapy for experimental pneumococcal meningitis.
abstract: An increased inflammatory mass in the subarachnoid space during bacterial meningitis may correlate with a poor outcome of disease. Using a rabbit model of pneumococcal meningitis, we sought to reduce this inflammatory process. The ability of the pneumococcal cell wall to cause death and to generate leukocytosis and abnormal chemistry in cerebrospinal fluid was prevented when animals were treated with inhibitors of cyclooxygenase pathway of arachidonate metabolism. Bacterial lysis by ampicillin led to release of cell wall that caused a significant, transient increase in meningeal inflammation. This inflammatory burst was also prevented by administering cyclooxygenase inhibitors concurrently with the antibiotic.
