Prevalence and outcomes of cerebral vasculitis in patients with comatose ventilated meningitis in the dexamethasone era

NRNicolas Roesch ECEmmanuel Canet

Key Points

This research investigates the prevalence and outcomes of cerebral vasculitis in comatose patients with bacterial meningitis receiving dexamethasone.
Examined cases of comatose patients with bacterial meningitis from a clinical setting.
Analyzed data on prevalence of cerebral vasculitis and associated clinical outcomes including mechanical ventilation and ICU stays.
Assessed the correlation between corticosteroid therapy usage and mortality in these patients.
Cerebral vasculitis was found in 22% of comatose patients with bacterial meningitis.
Patients with vasculitis experienced longer mechanical ventilation times and extended ICU stays.
Increased mortality was observed in patients affected by vasculitis compared to those without.

Abstract

Cerebral vasculitis affected 22% of comatose patients with bacterial meningitis, predominantly Streptococcus pneumoniae, despite high dexamethasone usage (85%). Vasculitis was associated with prolonged mechanical ventilation, extended ICU stays, and increased mortality. Further research is required to refine therapeutic strategies and clarify the impact of corticosteroid therapy.
