Resumen
Introducción

Nos proponemos recoger la experiencia de uso de raltegravir en el contexto del tratamiento antirretroviral de gran actividad (TARGA) en pacientes de alto riesgo vascular.

Método

Estudio retrospectivo de casos y controles. Los casos fueron aquellos pacientes que al comenzar con raltegravir presentaban un riesgo de enfermedad cardiovascular ≥ 20% según el algoritmo de la Sociedad Europea de Sida. Debían haber permanecido con dicho tratamiento durante al menos seis meses. Se parearon controles 1:1 con riesgo vascular también ≥ 20%.

Resultados

Se seleccionaron diez casos y diez controles. Tras seis meses de uso de raltegravir, se observó un descenso de los valores de colesterol unido a lipoproteínas de alta densidad (colesterol HDL) (-2,5mg/dL en los controles frente a 2,5mg/dL en los casos, p=0,015), triglicéridos (10mg/dL frente a -101mg/dL, p=0,009), y en la ratio colesterol total/colesterol HDL (0,17 frente a -0,73, p=0,002). El riesgo de enfermedad cardiovascular a diez años disminuyó un 4,85% en los casos frente a un 0,05% en los controles (p=0,07).

Conclusiones

Raltegravir muestra un buen perfil para ser usado en pacientes de alto riesgo vascular, con descenso de la ratio colesterol total/colesterol HDL y del riesgo vascular.

Abstract
Objectives

To record the experience with use of raltegravir (RTG) for devising highly active antiretroviral therapy (HAART) regimens based on RTG in high vascular risk patients.

Methods

A retrospective study was conducted on high vascular risk patients taking RTG. Case was a patient who, at the time raltegravir was started, had ≥ 20% 10-year risk of cardiovascular disease, estimated by the algorithm of the European AIDS Clinical Society. Patients should have been on stable HAART including RTG for at least six months. A matched control with ≥ 20% risk of cardiovascular disease, was selected for each case.

Results

Ten controls and ten cases were selected. After six months using RTG, a significant decreased was seen in levels of HDL cholesterol (median -2,5mg/dL in controls versus 2,5mg/dL in cases, p=0.015), triglycerides (10mg/dL versus -101mg/dL, p=0.009), and TC/HDL-C ratio (0.17 versus -0.73, p=0.002). Ten-year risk of cardiovascular disease was -4.85% in cases versus -0.05% in controls (p=0.07).

Conclusions

RTG shows a good profile to be used in people with high vascular risk, with a decrease in TC/HDL-C ratio and vascular risk.
