The use of adjunctive therapy to alter the pathophysiology of bacterial meningitis.
The inflammation in the subarachnoid space (SAS) that develops in the course of bacterial meningitis may have a role in eradicating the infection, but also, ultimately, is the cause of the neurological sequelae associated with this infection. The presence of an inflammatory exudate in the SAS leads to alterations in the blood-brain barrier, altered cerebrospinal fluid dynamics, cerebral edema and increased intracranial pressure, and loss of cerebral auto-regulation. Our increasing understanding of the pathophysiology of meningeal inflammation has led to therapeutic interventions to limit the degree of meningeal inflammation and neurologic sequelae. The inflammatory cascade that leads to alterations in central nervous system physiology will be reviewed as well as the experimental evidence and clinical trials demonstrating the efficacy of adjunctive therapy in reducing meningeal inflammation and decreasing the incidence and severity of neurological sequelae in bacterial meningitis.
