Résumé
As routine viral load testing among HIV-infected individuals on antiretroviral therapy (ART) expands, virologic failure (VF) among children in developing countries remains poorly understood. We assessed the rate of VF, the proportion failing who were subsequently switched to second-line ART and factors associated with VF among children ≤18 y. An observation cohort study among 1312 children at two public clinics in Lilongwe, Malawi who initiated a first-line ART regimen between January 2014 and December 2017 and remained on treatment for ≥6 mo was conducted. Kaplan-Meier methods estimated the probabilities of VF. Univariable and multivariable Poisson regression models were used to explore predictors of VF. Overall, 16% (208/1312) of children experienced VF with an incidence rate of 10.1 events per 100 person-years. Of the 208, 184 (88%) were switched to second-line ART: 68 (43%) switched the same day VF was confirmed and 106 (66%) switched within 90 d of confirmed VF. Use of a Nevirapine (NVP)-based regimen and initiating ART in 2016-2017 compared with 2014-2015 were independent predictors of VF. VF is common among children receiving ART. The findings suggest that VF can be reduced by phasing out NVP-based regimen and by ensuring optimal adherence to ART.

BACKGROUND
As routine viral load testing among HIV-infected individuals on antiretroviral therapy (ART) expands, virologic failure (VF) among children in developing countries remains poorly understood. We assessed the rate of VF, the proportion failing who were subsequently switched to second-line ART and factors associated with VF among children ≤18 y.
METHODS
An observation cohort study among 1312 children at two public clinics in Lilongwe, Malawi who initiated a first-line ART regimen between January 2014 and December 2017 and remained on treatment for ≥6 mo was conducted. Kaplan-Meier methods estimated the probabilities of VF. Univariable and multivariable Poisson regression models were used to explore predictors of VF.
RESULT
Overall, 16% (208/1312) of children experienced VF with an incidence rate of 10.1 events per 100 person-years. Of the 208, 184 (88%) were switched to second-line ART: 68 (43%) switched the same day VF was confirmed and 106 (66%) switched within 90 d of confirmed VF. Use of a Nevirapine (NVP)-based regimen and initiating ART in 2016-2017 compared with 2014-2015 were independent predictors of VF.
CONCLUSION
VF is common among children receiving ART. The findings suggest that VF can be reduced by phasing out NVP-based regimen and by ensuring optimal adherence to ART.
