Antibiotic Resistance among Pathogens Causing Disease in Jamaican Children with HIV/AIDS



Objective: There are limited data regarding the antimicrobial resistance patterns of pathogens in children with HIV/AIDS from developing countries. We aimed to determine the prevalence and antibiotic susceptibility patterns of bacterial pathogens causing urinary tract infections (UTIs) and sepsis in a cohort of 219 HIV-infected Jamaican children.

Methods: This cross-sectional study examined clinical and microbiological data for children enrolled in the Kingston Paediatric/Perinatal HIV/AIDS programme from September 1, 2002 to May 31, 2007. Cases were defined as physician-diagnosed, laboratory confirmed UTIs and sepsis based on Centers for Disease Control and Prevention (CDC) criteria. Only isolates from urine, blood and sterile sites were considered.

Results: Forty-four patients (20.1%) accounted for 74 episodes of UTIs and sepsis. Mean number of infections was 1.7 ± 1.3 per patient. There were 31 males (70.5%) and mean age at time of infection was 5.6 ± 4.7 years. Bacterial infections comprised cystitis (n = 52, 70.3%), bacterial pneumonia (n = 15, 20.3%), meningitis (n = 4, 5.4%), septicaemia (n = 2, 2.7%) and bone infection (n = 1, 1.4%). Among 52 UTIs, 39 were caused by a single organism. The most common UTI isolates included Escherichia coli (n = 21, 53.8%) and Enterobacter spp (n = 5, 12.8%). Among 22 cases of sepsis, isolates included Streptococcus pneumoniae (n = 8, 36.4%) and coagulase negative Staphylococcus (n = 6, 27.3%). All E coli isolates at two of three clinical sites were resistant to cotrimoxazole. There were 79.7% (n = 51) of infectious episodes with a cotrimoxazole-resistant organism occurring among those on cotrimoxazole prophylaxis.

Conclusions: Escherichia coli was the most frequent bacterial isolate. Cotrimoxazole is a poor choice for empiric treatment of sepsis and UTIs in this clinical setting.
