Cochrane review: Corticosteroids for acute bacterial meningitis

摘要

Background nIn experimental studies, the clinical outcome of acute bacterial meningitis has been related to the severity of the inflammatory process in the subarachnoidal space. Treatment with corticosteroids can reduce this inflammatory response and thereby may improve outcome. We conducted a meta-analysis of randomised controlled trials (RCTs) of adjuvant corticosteroids in the treatment of acute bacterial meningitis. nnObjectives nWe conducted a systematic review examining the efficacy and safety of adjuvant corticosteroid therapy in acute bacterial meningitis. nnSearch strategy nIn this updated review, we searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 2, 2006); MEDLINE (1966 to July 2006); EMBASE (1974 to June 2006); Current Contents (2001 to June 2006); and reference lists of all articles. We also contacted manufacturers and researchers in the field. nnSelection criteria nEligible published and non-published RCTs on corticosteroids as adjuvant therapy in acute bacterial meningitis. Patients of any age and in any clinical condition, treated with antibacterial agents and randomised to corticosteroid therapy (or placebo) of any type, could be included. At least case fatality rate or hearing loss had to be recorded for inclusion.
