Biterapia como alternativa de tratamiento en los pacientes VIH pretratados: experiencia en un hospital de tercer nivel / Dual therapy as an alternative treatment in HIV pretreatred patients: experience in a tertiary hospital

INTRODUCCIÓN: La biterapia se plantea como una alternativa efectiva para prevenir la aparición de efectos secundarios y comorbilidades asociadas al tratamiento prolongado con antirretrovirales (ARV) y una forma de simplificación del tratamiento antirretroviral (TAR) para mejorar la adherencia en determinados pacientes, además de una posible opción de tratamiento en pacientes en los que hayan fracasado TAR previos. MÉTODOS: El objetivo del estudio es describir la efectividad, grado de adherencia y costes de los regímenes de biterapia utilizados en los pacientes VIH pretratados en un hospital de tercer nivel. RESULTADOS: Se estudiaron 38 pacientes (8 se excluyeron). Los principales motivos de cambio a biterapia fueron evitar los efectos adversos del TAR anterior (40%), la simplificación (36,67 %) y el rescate virológico (20%). Los esquemas de bi¬terapia más utilizados fueron: IP/r + INI (26,67%), IP/r + ITIAN (23,33%), IP/r + ITINN (23,33%), IP/r + CCR5 (16,66%) e INI + ITINN (10%). Los ARV más utilizados fueron: DRV/r + RAL en el 23,33 % de los pacientes; DRV/r + 3TC en el 20% y DRV/r + ETR en el 16,67 %. La adherencia antes del cambio a biterapia fue del 86,79% y tras el cambio a biterapia fue del 96,27%. El ahorro económico que supuso el cambio a biterapia de estos pacientes fue de 3.635,16 €. CONCLUSIÓN: La biterapia con IP/r se plantea como una alternativa eficiente comparada con la terapia convencional en pacientes pretratados

INTRODUCTION: Dual therapy regimen might be an effective alternative to prevent the occurrence of side effects and comorbidities associated with prolonged treatment with antiretroviral (ARV) and a way of simplification of antiretroviral therapy (ART) to improve adherence in certain patients. It also represents a potential treatment option for patients who have failed previous TAR. METHODS: The aim of the study is to describe the effectiveness, adherence and costs of dual therapy regimen used in pretreated HIV patients in tertiary hospital. RESULTS: Thirty-eight patients were studied (eight were excluded). Reasons for simplification to dual therapy were previous treatment toxicity (40%), simplification (36.67%) and virological rescue (20%). The dual therapy regimens most used were: IP/r + INSTIs (26.67%), IP/r + NRTIs (23.33%), IP/r + NNRTIs (23.33%), IP/r+ CCR5 (16.66%) e INSTIs + NNRTIs (10%). ARV more used were darunavir/ritonavir (DRV/r) + raltegravir (23.33 %); DRV/r + lamivudine (20%) y DRV/r + etravirine (16.67 %). Adherence was 86.79% before switching to dual therapy and 96.27% after switching. The cost savings of switching to dual therapy of these patients was € 3,635.16. DISCUSSION: Dual therapy with IP/r might be an effective alternative to selected treatment experienced patients compared with conventional therapy
