Article information

En el estudio ARTEMIS se ha comparado la eficacia de darunavir (DRV)/ritonavir (r) a dosis de 800/100 mg 1 vez al día (qd), frente a lopinavir (LPV)/r qd o 2 veces al día (bid), junto con tenofovir 300 mg y emtricitabina 200 mg, ambos qd, en pacientes naïve. Los resultados a las 48 semanas muestran que DRV/r es no inferior a LPV/r; el aumento de CD4 observado con ambos regímenes es similar. DRV/r fue superior a LPV/r en los pacientes que presentaban cargas virales altas (> 100.000 copias/ml). El uso de DRV/r se asoció a una menor proporción de efectos adversos grados 2-4, en especial de carácter gastrointestinal, como diarrea, y también con una menor frecuencia de efectos adversos lipídicos, como aumento de triglicéridos y colesterol total. DRV/r qd puede ser una opción en el tratamiento antirretroviral de primera línea, con la ventaja añadida de una dosis reducida de ritonavir y de la gran eficacia en pacientes con cargas virales elevadas.

The ARTEMIS study compared the efficacy of darunavir/ritonavir at once-daily doses of 800/100 mg versus once- or twice-daily doses of lopinavir/ritonavir, together with 300 mg of tenofovir and 200 mg of emtricitabine, both in once-daily doses, in treatment-naive patients. The results at 48 weeks show that darunavir/ritonavir is not inferior to lopinavir/ritonavir; the increase in CD4 count observed with both regimens was similar. Darunavir/ritonavir was superior to lopinavir/ritonavir in patients with high viral loads (>100,000 copies/mL). The use of darunavir/ritonavir was associated with a lower proportion of grades 2-4 adverse effects, especially gastrointestinal effects such as diarrhea and with a lower frequency of lipidic adverse effects, such as increased triglyceride and total cholesterol levels. Once-daily darunavir/ritonavir may be an option in firstline antiretroviral therapy, with the added advantage of a reduced dose of ritonavir and high efficacy in patients with elevated viral loads.
