BackgroundTuberculous meningitis (TBM) is a devastating infection in tuberculosis endemic areas with limited access to intensive care. Functional outcomes of severe adult TBM patients admitted to the ICU in nonendemic areas are not known.MethodsWe conducted a retrospective multicenter cohort study (2004-2016) of consecutive TBM patients admitted to 12 ICUs in the Paris area, France. Clinical, biological, and brain magnetic resonance imaging (MRI) findings at admission associated with a poor functional outcome (i.e., a score of 3-6 on the modified Rankin scale (mRS) at 90 days) were identified by logistic regression. Factors associated with 1-year mortality were investigated by Cox proportional hazards modeling.ResultsWe studied 90 patients, of whom 61 (68%) had a score on the Glasgow Coma Scale ≤ 10 at presentation and 63 (70%) required invasive mechanical ventilation. Brain MRI revealed infarction and hydrocephalus in 38/75 (51%) and 25/75 (33%) cases, respectively. A poor functional outcome was observed in 55 (61%) patients and was independently associated with older age (adjusted odds ratio (aOR) 1.03, 95% CI 1.0-1.07), cerebrospinal fluid protein level ≥ 2 g/L (aOR 5.31, 95% CI 1.67-16.85), and hydrocephalus on brain MRI (aOR 17.2, 95% CI 2.57-115.14). By contrast, adjunctive steroids were protective (aOR 0.13, 95% CI 0.03-0.56). The multivariable adjusted hazard ratio of adjunctive steroids for 1-year mortality (47%, 95% CI 37%-59%) was 0.23 (95% CI 0.11-0.44). Among survivors at 1 year, functional independence (mRS of 0-2) was observed in 27/37 (73%, 95% CI 59%-87%) cases.ConclusionsA poor functional outcome in adult TBM patients admitted to the ICU in a nonendemic area is observed in 60% of cases and is independently associated with elevated cerebrospinal fluid protein level and hydrocephalus. Our data also suggest a protective effect of adjunctive steroids, with reduced disability and mortality, irrespective of immune status and severity of disease at presentation. One-year follow-up revealed functional independence in most survivors.
