Drug resistance profiling, antimicrobial susceptibility and demographic characteristics of children with acute bacterial meningitis in a Southeastern tertiary health facility

Background Over the years, varying patterns of bacterial susceptibility and multidrug resistance (MDR) rates have been reported in different settings. Detailed evaluation of the drug profile of the bacterial pathogens implicated in children with invasive bacterial infection helps to reduce the heightened risk of adverse events that could follow poorly managed or complicated cases in resource limited environment like ours. This study therefore, aimed to highlight the antibiotic susceptibility and MDR rate, and establish the relationship if any, between demographic characteristics and positive CSF- bacterial isolates of post neonatal children with suspected acute bacterial meningitis (ABM). The findings would guide practitioners on the empirical antimicrobials to consider in the event of clinical suspicion of ABM pending the availability of CSF isolates' antibiogram.

Methods A prospective review of 100 children with clinical suspicion of ABM from January 2016- December 2020. Descriptive statistics, chi square and regression analysis were used to establish MDR rates, Isolates' susceptibility pattern and the relationship between demographic variables and positive isolates respectively. P<0.05 was accepted as significant.

Results Fluroquinolones, cephalosporins, imipenem and aminoglycosides were susceptible anti-microgram in children with ABM. Sixty-four (85.5%) of the isolates showed MDR pattern, and young children (infants and toddlers) were significantly associated with positive CSF bacterial isolates.

Conclusions ABM should be treated with combination of CNS penetrating empirical antibiotics due to rising rate of MDR pathogens. Young children with febrile illnesses should be thoroughly evaluated for possibility of CNS infection.
