Official title: A Randomized Trial to Investigate Strategies to Reduce Mortality Among HIV-infected and HIV-exposed Children Admitted With Severe Acute Malnutrition in Mulago Hospital, Kampala, Uganda

Status Recruiting

Clinical Trial Summary

This study to investigate whether empiric use of an antibiotic with greater antimicrobial sensitivity (ceftriaxone) than standard-of-care (ampicillin plus gentamicin) will reduce mortality among HIV-infected/HEU children admitted to Mwanamugimu Nutrition Unit, Mulago Hospital, Kampala, Uganda.

Clinical Trial Description

Background

HIV-infected and HIV-exposed-uninfected children (HEU) are at increased risk of developing malnutrition. Severely malnourished children have high mortality rates, but mortality is higher in those that are HIV-infected. Preliminary audits at the Mwanamugimu Nutrition Unit, Mulago Hospital, in 2014 showed that 43% of the severely malnourished children that died were HIV-infected/HEU, despite only 30% of admissions being HIV-infected/HEU, with deaths due to infections in 90% of cases.

Objectives

This study aims to investigate whether empiric use of an antibiotic with greater antimicrobial sensitivity (ceftriaxone) than standard-of-care (ampicillin plus gentamicin) will reduce mortality among HIV-infected/HEU children admitted to Mwanamugimu Nutrition Unit. Secondary objectives include: comparing length of hospitalization, weight-for-height, weight-for-age and height-for-age z-scores between ceftriaxone versus standard of care (ampicillin and gentamicin) treatment arms; ascertaining the pattern/antimicrobial sensitivity of pathogens among participants; determining the prevalence and factors associated with HIV-infection among severely malnourished children; and evaluating the pharmacokinetics (PK) of lopinavir/ritonavir (LPV/r) among severely malnourished HIV-infected children.

Methods

This will be an open label randomized controlled trial involving 300 children; 76 HIV-infected (current mortality - 33%) and 224 HEU (current mortality - 26%). The participants will be randomized to receive 1week of ceftriaxone (n= 150) or standard-of-care (ampicillin/gentamicin) (n=150), in addition to other routine care; the ratio of HIV-infected to HEU (1:3) in this sample is reflective of the current proportions of the HIV-infected and HEU children admitted at Mwanamugimu Nutrition Unit. The trial's primary outcome will be in hospital mortality. 300 randomised children provides >80% power to detect reductions in mortality from the expected 28% to 14%, allowing for 10% noncompliance/lost-to-follow-up in each group. Secondary outcomes will be: length of hospitalization; weight-for-height, weight-for-age and height-for-age z-scores; and pattern/antimicrobial sensitivity of pathogens. In addition, 280 severely malnourished children of unknown serostatus will be tested for HIV at admission to determine the prevalence and factors associated with HIV-infection. 280 children provide 80% power to determine the prevalence of HIV-infection. Furthermore, all the HIV-infected children on LPV/r will each provide sparse pharmacokinetic (PK) samples to evaluate the PK of LPV/r among malnourished children. In this PK sub-study, geometric means of steady-state LPV PK parameters [Area Under the Curve (AUC) 0-12h, maximum concentration (Cmax) and concentration at 12 hours after dose (C12h)] will be determined. The PK parameters (AUC 0-12h, Cmax, C12) will then be put in pharmacokinetic-pharmacodynamic (PK-PD) models to determine optimal doses for the study population. ;
