Acute kidney injury in HIV-infected children: comparison of patients according to the use of highly active antiretroviral therapy

Abstract

AbstractObjectiveTo assess clinical and laboratory data, and acute kidney injury (AKI) in HIV-infected children using and not using highly active antiretroviral therapy (HAART) prior to admission.MethodsA retrospective study was conducted with HIV-infected pediatric patients (<16 years). Children who were using and not using HAART prior to admission were compared.ResultsSixty-three patients were included. Mean age was 5.3±4.27 years; 55.6% were females. AKI was observed in 33 (52.3%) children. Patients on HAART presented lower levels of potassium (3.9±0.8 vs. 4.5±0.7mEq/L, p=0.019) and bicarbonate (19.1±4.9 vs. 23.5±2.2mEq/L, p=0.013) and had a higher estimated glomerular filtration rate (102.2±36.7 vs. 77.0±32.8mL/min/1.73m2, p=0.011) than those not on HAART. In the multivariate analysis, the use of HAART prior to the admission was a protective factor for AKI (p=0.036; OR=0.30; 95% CI=0.097–0.926).ConclusionAKI is a common complication of pediatric HIV infection. Use of HAART prior to the admission preserved glomerular filtration and was a protective factor for AKI, but increased medication side effects, such as hypokalemia and renal metabolic acidosis
