HIV Children Very Vulnerable to Infection

Link: HighWire Press -- Medline Abstract.

Seventy-seven percent of S. aureus were MRSA. Carriage of resistant organisms was not associated with hospitalization. On multivariate logistic regression, risk factors for colonization with Enterobacteriaceae were age below one year (Odds ratio 4.4; 95% Confidence Interval 1.9-10.9; p = 0.0008) and CDC stage C disease (Odds ratio 3.6; 95% Confidence Interval 1.5-8.6; p = 0.005) Nineteen (9.4%) subjects had 23 episodes of bacteremia. Enterobacteriaceae were most commonly isolated (13 of 25 isolates), of which 6 (46%) produced ESBL and were resistant to gentamicin. CONCLUSIONS: HIV-infected children are colonized with potential pathogens, most of which are resistant to commonly used antibiotics. TMP-SMX resistance is extremely common. Antibiotic resistance is widespread in colonizing organisms and those causing invasive disease. Antibiotic recommendations should take cognizance of resistance patterns. Antibiotics appropriate for ESBL-producing Enterobacteriaceae and MRSA should be used for severely ill HIV-infected children in our region. Further study of antibiotic resistance patterns in HIV-infected children from other areas is needed.
