Abstract
Recent major epidemiologic trends in bacterial meningitis include a dramatic decline in the incidence of Haemophilus influenzae meningitis since the introduction of the protein-conjugated H. influenzae vaccines, and a worldwide increase in infections with antibiotic-resistant strains of bacterial pathogens. Cases of meningitis caused by resistant strains require an alternative therapeutic strategy. Animal studies have identified inflammatory mediators, eg, chemokines, excitatory amino acids, and endothelins, which are involved in the pathophysiology of bacterial meningitis. There is increasing evidence that reactive oxygen species (ROS), reactive nitrogen species, peroxynitrite, and matrix metalloproteinases contribute to brain damage during bacterial meningitis. The cytotoxic effects of ROS and peroxynitrite include the initiation of lipid peroxidation and the induction of DNA single-strand breakage. Damaged DNA activates poly(ADP-ribose) polymerase (PARP). Recent experimental data suggest that lipid peroxidation and PARP activation play a role in the development of meningitis-associated intracranial complications and brain injury. Agents that interfere with the production of ROS and peroxynitrite, and interfere with lipid peroxidation and PARP activation, may represent novel, therapeutic strategies by which meningitisassociated brain damage can be limited, therefore improving the outcome of this serious disease.
