Over the past 5 yr, we have conducted two clinical and two pharmacokinetic investigations of cefotaxime (CTX) and desacetylcefotaxime (dCTX) in neonates, infants, and children. A total of 50 children with culture-proven bacterial meningitis were randomized to receive either 200 mg/kg/day of CTX (n = 23, mean age 24.4 mo) or standard doses of ampicillin (AMP) and chloramphenicol succinate (CAPS; n = 27, mean age 16.6 mo). Results were similar between the CTX and Amp/CAPS groups for clinical/microbiological cures (100% versus 96%, respectively) and for survival without sequelae (78% vs. 77%, respectively). All bacterial isolates were sensitive to CTX, and the comparison of the MIC/MBC values for CTX to the CSF bactericidal titers suggested antimicrobial activity for dCTX. In a second clinical trial, 20 infants (1 wk-3 mo) were treated with 200 mg/kg/day of CTX for Gram-negative enteric bacillary meningitis. Cultures of CSF obtained 24 hr after the initiation of treatment were sterile in all subjects. Survival and complication rates of 95% and 21%, respectively, were observed. This compared favorably to previously published experiences with alternate treatment regimens for Gram-negative meningitis in the newborn. In both meningitis studies, the safety profile for CTX was excellent.(ABSTRACT TRUNCATED AT 250 WORDS)

The objective of this study was to determine if the current dosage regimen for chloramphenicol CAP administered to children with severe malaria SM for presumptive treatment of concomitant bacterial meningitis achieves steady state plasma CAP concentrations within the reported therapeutic range of 10-25 mg/l. Fifteen children (11 male, 4 female) with a median age of 45 months (range: 10-108 months) and having SM, were administered multiple intravenous doses (25 mg/kg, 6 hourly for 72 h) of chloramphenicol sodium succinate CAPS for presumptive treatment of concomitant bacterial meningitis. Blood samples were collected over 72 h, and plasma CAPS, CAP and CSF CAP concentrations determined by high performance liquid chromatography. Average steady state CAP concentrations were approximately 17 mg/l, while mean fraction unbound (0.49) and CSF/plasma concentration ratio (0.65) were comparable to previously reported values in Caucasian children. Clearance was variable (mean = 4.3 l/h), and trough plasma concentrations during the first dosing interval were approximately 6 mg/l. Simulations indicated that an initial of loading dose of 40 mg/kg CAPS, followed by a maintenance dose of 25 mg/kg every 6 h would result in trough CAP concentrations of approximately 10 mg/l and peak concentrations <25 mg/l throughout the treatment period. The current dosage regimen for CAP needs to include a loading dose of 40 mg/kg CAPS to rapidly achieve plasma CAP concentrations within the reported therapeutic range.
