Abstract

Background:

The World Health Organization recommends benzylpenicillin and gentamicin as antimicrobial treatment for infants with sepsis in low-income settings, and ceftriaxone or cefotaxime as an alternative. In a meta-analysis from 13 low-income settings, Staphylococcus aureus, Klebsiella spp. and Escherichia coli accounted for 55% of infants with sepsis. In a review of bacterial meningitis, resistance to third generation cephalosporins was >50% of all isolates, and 44% of Gram-negative isolates were gentamicin resistant. However, ceftriaxone may cause neonatal jaundice, and gentamicin may cause deafness. Therefore, we compared parenteral benzylpenicillin plus gentamicin with ceftriaxone as first-line treatment, assessing outcome and adverse events.

Methods:

This was an open randomized trial carried out in the Queen Elizabeth Central Hospital, Blantyre, Malawi, from 2010 to 2013. Infants <60 days of age with possible severe sepsis received either benzylpenicillin and gentamicin or ceftriaxone. Adverse events and outcomes were recorded until 6 months post discharge.

Results:

Three-hundred forty-eight infants were included in analyses. Outcome in the benzylpenicillin and gentamicin and ceftriaxone groups was similar; deaths were 13.7% and 16.5% and sequelae were 14.5% and 11.2%, respectively. More infants in the penicillin/gentamicin group required phototherapy: 15% versus 5%, P = 0.03. Thirteen (6%) survivors had bilateral hearing loss. There was no difference between the treatment groups. By 6 months post discharge, 11 more infants had died, and 17 more children were found to have sequelae.

Conclusions:

Ceftriaxone and gentamicin are safe for infants in our setting. Infants should receive long-term follow-up as many poor outcomes occurred after hospital discharge.
