[Efficacy of initial antiretroviral therapy based on lopinavir/ritonavir plus 2 nucleoside/nucleotide analogs in patients with human immunodeficiency virus type 1 infection]. / Eficacia del tratamiento antirretroviral de inicio basado en lopinavir/ritonavir más 2 análogos de nucleósidos/nucleótidos en pacientes infectados por el virus de la inmunodeficiencia humana-1.

ABSTRACT

Triple combination regimens consisting of lopinavir/ritonavir (LPV/r) plus 2 nucleoside/nucleotide analogs continue to be a valid option in initial antiretroviral therapy. Other protease inhibitors boosted with ritonavir (and in future with cobicistat) have been introduced, as well as other non-nucleoside analogs (rilpivirin) and 3 integrase inhibitors. None of the new regimens have shown superiority over LPV/r or comparisons are lacking. Therefore, regimens including LPV/r continue to be recommended as initial first-line or alternative strategies in most treatment guidelines. Dual combinations with LPV/r (plus raltegravir or lamivudine) are described in another article and can provide a similar response rate to triple combinations, better tolerance, and an improved cost-efficacy ratio, both for initial therapy and in simplification strategies. In contrast, LPV/r or darunavir/r monotherapy does not seem an acceptable option in treatment-naïve patients and is becoming increasingly less acceptable in simplification strategies.
