Extended Continuous β-Lactam Infusion With Oral Acetaminophen in Childhood Bacterial Meningitis: A Randomized, Double-blind Clinical Trial

Background In our previous study in Luanda, Angola, initial continuous β-lactam infusion for 24 hours combined with oral acetaminophen for 48 hours showed promising results as a new treatment for childhood bacterial meningitis. We investigated whether extending this treatment regimen to 4 days would improve the outcomes further. Methods We conducted a randomized, double-blind, parallel-group study at the same hospital in Luanda. Children aged 2 months to 15 years presenting to hospital with symptoms and signs of bacterial meningitis were randomized to receive, for the first 4 days, a continuous infusion of cefotaxime (250 mg/kg/day) with simultaneous oral acetaminophen (first dose 30 mg/kg, then 20 mg/kg every 6 hours), or cefotaxime conventionally as boluses (62.5 mg/kg, 4 times per day) with placebo orally. All children received also glycerol orally. The primary outcome was mortality by day 7. Results In all, 375 patients were included in the study between 22 January 2012 and 21 January 2017. As 2 children succumbed before treatment initiation, 187 vs 186 participants remained in the intervention and control groups, respectively. On day 7, 61 of 187 (32.6%) children in the intervention group vs 64 of 186 (34.4%) in the control group had died (risk ratio, 0.95 [95% confidence interval {CI}, .71–1.26]; absolute risk difference, 1.8% [95% CI, −7.8 to 11.4]). At discharge from hospital, the corresponding numbers were 71 of 187 (38.0%) and 75 of 186 (40.3%), respectively. Conclusions Prolonged continuous β-lactam infusion combined with oral acetaminophen did not improve the gloomy outcomes of childhood bacterial meningitis in Angola.
