Resumen

El manejo del trastorno por consumo de alcohol (TCA) resistente al tratamiento presenta desafíos. La terapia de exposición a señales con realidad virtual (TES-RV) es un enfoque complementario al tratamiento estándar (TE). Este ensayo clínico aleatorizado (ECA) evaluó la eficacia de TES-RV con TE, comparado con TE solo, para reducir craving y ansiedad por el alcohol en pacientes con TCA resistente. También buscó determinar niveles de craving y ansiedad durante las sesiones de TES-RV y explorar efectos a largo plazo en la abstinencia. Participaron 85 pacientes con TCA del Hospital Clínic de Barcelona. Fueron asignados aleatoriamente a un grupo experimental (GE), con TES-RV más TE, o a un grupo control (GC), solo con TE. El GE completó seis sesiones de TES-RV junto con TE; el GC continuó solo con TE. Se evaluaron craving y ansiedad por el alcohol antes y después del tratamiento en ambos grupos, y durante las sesiones de TES-RV en el GE. Las recaídas se monitorizaron a los 3, 6 y 12 meses post-tratamiento. Los resultados no mostraron efectos significativos del tipo de tratamiento (GE vs. GC) sobre craving ni ansiedad. No obstante, un factor temporal significativo indicó reducciones en craving y ansiedad del pretest al postest, independientemente del tratamiento. Durante las sesiones de TES-RV, los participantes del GE reportaron niveles mínimos de craving y ansiedad al finalizar. No se hallaron diferencias estadísticamente significativas en las tasas de recaída entre el GE y el GC en ningún seguimiento. El estudio discute implicaciones clínicas, limitaciones y futuras líneas de investigación.
