RESUMEN
Resumen

Introducción:

A nivel mundial, la tasa global de resistencia primaria y secundaria a los anti-retrovirales (ARV) es de 15 y 40%, respectivamente. Se desconoce su prevalencia en Uruguay.

Objetivo:

Conocer la prevalencia de resistencia a los ARV en niños y adolescentes uruguayos bajo 15 años de edad infectados con VIH que se controlan en el Centro Hospitalario Pereira Rossell entre 2008 y 2016. Objetivos específicos Cuantificar mutaciones de resistencia primarias y secundarias e identificar variables asociadas a resistencias; describir si el resultado del test de resistencia contribuyó a lograr una carga viral (CV) indetectable.

Metodología:

Descriptivo observacional, seguimiento longitudinal. Se incluyeron menores de 15 años con test de resistencia entre 1 de enero de 2008 y 15 de diciembre de 2016. Variables maternas y del niño.

Resultados:

Se incluyeron 56 niños. Tenían test de resistencia previo al inicio TARV 36 niños (64%) y por fallo terapéutico 20 (36%). La resistencia total fue 28,6% (16 niños) cuatro (11,1%) con mutaciones primarias y 12 (60%) secundarias. El test modificó el plan ARV en 15 (26,7%) de los 56 niños. El cambio logró CV indetectable a los seis meses en ocho casos. El cambio de TARV no se asoció con sida o muerte.

Discusión:

Los estudios de prevalencia son útiles para la toma de decisiones sobre la selección inicial de ARV. La prevalencia de mutaciones primarias fue similar a la publicada, mientras que la secundaria fue mayor.
ABSTRACT

Background:

Primary and secondary antiretroviral (ARV) resistance rates of 15 and 40% respectively have been reported in worldwide. Its prevalence in Uruguay is unknown.

Aim:

To know the prevalence of ARV resistance in Uruguayan children under 15 years old infected with HIV that are controlled in the Centro Hospitalario Pereira Rossell between 2008 and 2016. Specific

objectives:

Quantify primary and secondary mutations, to identify variables associated with resistance; to describe if the result of the resistance test contributed to achieve undetectable viral load (VL). Methodos Observational descriptive, longitudinal follow-up. Only children under 15 years with resistance test done between January first 2008 and December 31th 2016 were included in the study. Maternal and child variables.

Results:

Fifty six children were included. 36 children (64%) had resistance tests prior to the initiation of ART and the other 20 children (36%) due to therapeutic failure. Total resistance 28.6% (16 children); 4 (11.1%) children with primary mutations and 12 (60%) secondary mutations. The test result changed the ARV plan in 15 (26.7%) of the 56 children. The change achieved undetectable CV in 8 children at month 6. The ART change was not associated with AIDS or death.

Discussion:

Prevalence studies are useful in making decisions about initial ARV treatment. The prevalence of primary mutations was similar to that published, while secondary prevalence was higher.
