Efficacy of Antibiotic Regimens for Sepsis or Possible Serious Bacterial Infection in Young Infants Aged 0 to 59 Days: A Systematic Review and Meta-analysis

Abstract

CONTEXT Sepsis is a leading cause of young infant mortality. OBJECTIVE To evaluate the efficacy of different antibiotic regimens to treat young infant sepsis or possible serious bacterial infection (PSBI) on clinical outcomes. DATA SOURCES MEDLINE, Embase, CINAHL, World Health Organization Global Index Medicus, Cochrane Central Registry of Trials. STUDY SELECTION We included randomized controlled trials (RCTs) of young infants 0 to 59 days with sepsis or PBSI (population) comparing the efficacy of antibiotic regimens (intervention) with alternate regimens or management (control) on clinical outcomes. DATA EXTRACTION We extracted data and assessed risk of bias in duplicate. We performed random-effects meta-analysis, and used Grading of Recommendations, Assessment, Development, and Evaluation to assess certainty of evidence. RESULTS Of 2390 publications, we included 41 RCTs (n = 18 054). Thirty-five trials were hospital-based and 6 were nonhospital-based. Meta-analysis of 4 trials demonstrated similar rates of treatment success with intramuscular/intravenous third generation cephalosporins versus intramuscular/intravenous penicillin or ampicillin + gentamicin (RR 1.03, 95% CI 0.93–1.13]; n = 1083; moderate certainty of evidence). Meta-analysis of 3 trials demonstrated similar rates of treatment failure with oral amoxicillin + intramuscular gentamicin versus intramuscular penicillin + gentamicin for nonhospital treatment of clinical severe illness (RR 0.86, 95% CI 0.72–1.02]; n = 5054; low certainty of evidence). Other studies were heterogeneous. LIMITATIONS RCTs evaluated heterogeneous regimens, limiting our ability to pool data. CONCLUSIONS We found limited evidence to support any single antibiotic regimen as superior to alternate regimens to treat young infant sepsis or PSBI.
