Tuberculous Meningitis — New Approaches Needed

This editorial evaluates a rigorously conducted randomized trial examining adjunctive dexamethasone for HIV-associated tuberculous meningitis. Despite prior evidence supporting glucocorticoid use, the current study found no significant mortality reduction among HIV-positive patients. The authors explore the complexity of host-pathogen interactions, immune dysregulation, and heterogeneity in inflammatory responses, suggesting that broad immunosuppressive strategies like dexamethasone may be inadequate for this population. They advocate for precision immunotherapy, enhanced supportive care, and novel anti-TB regimens tailored to the disease's unique pathophysiology. Despite its negative findings, the trial underscores the urgent need for innovative treatment approaches in tuberculous meningitis.
