The role of aspirin in childhood tuberculous meningitis.

Arterial stroke is the main cause of poor outcome in childhood tuberculous meningitis. Aspirin has an antithrombotic action at low dose and anti-ischemic and anti-inflammatory properties, which are dose-related. The aim of the study was to explore the possible benefits of aspirin in children with tuberculous meningitis. A total of 146 consecutive children with a diagnosis of probable tuberculous meningitis were studied. Patients were randomized into 3 groups: (1) placebo group, (2) low-dose aspirin group, and (3) high-dose aspirin group. Twenty-nine additional patients who received aspirin before admission were excluded from the randomized study, but continued on low-dose aspirin. Aspirin, irrespective of dose, did not show any significant benefit regarding morbidity (hemiparesis and developmental outcome) and mortality. Aspirin was well tolerated, but 1 death was probably related to aspirin. The fact that the outcome of the high-dose aspirin group compared favorably with the other treatment groups despite younger age and more severe neurological involvement at baseline needs further investigation.
