Popis: | Decreased antiretroviral therapy persistence is associated with increased rates of virologic failure, development of antiretroviral resistance, and increased morbidity and mortality. Different therapeutic strategies, such as single-tablet regimens (STR) and less-drug regimens (LDR), have been developed in order to simplify antiretroviral therapy (ART) and increase persistence.The primary objective was to compare antiretroviral persistence among patients receiving STRs and patients receiving LDRs. A secondary objective was to identify factors associated with non-persistence.This was a retrospective study that included treatment- experienced HIV-infected patients who received ART based on STR or LDR. Baseline patient characteristics collected included demographic information, HIV risk transmission, substance abuse during the therapy, presence of psychiatric disorder and hepatitis B or C virus infection. Kaplan-Meier analysis and Log rank was utilized to compare persistence to STR and LDR. To identify independent predictors of non-persistence we developed a multivariate Cox regression analysis.A total of 244 patients were included, 176 with STR and 68 with LDR. 60 (34.1%) patients discontinued in the STR group and 13 (19.1%) in the LDR group. The Cox regression model showed that the only variable associated with higher risk of non-persistence was the substance abuse (HR = 2.59; p = 0.005). Adverse events were the main reason for ART discontinuation in the STR group and virologic failure in the LDR group.Persistence to STR and LDR seems to be similar in pretreated HIV-infected patients. Drug abuse was the only factor identified with a higher risk of non-persistence.Objetivos: Analizar y comparar la persistencia entre las estrategias basadas en Single-Tablet Regimen (STR) y Less Drug Regimen (LDR) en pacientes VIH+. El objetivo secundario del estudio fue determinar factores predictores de persistencia. Material y métodos: Estudio observacional retrospectivo que incluyo los siguientes criterios: pacientes VIH+ con tratamiento antirretroviral (TAR) con un regimen basado en STR o LDR. Se recogieron variables demograficas, factores de riesgo de adquisicion, consumo de drogas, presencia de algun trastorno psiquiatrico y coinfeccion por el virus de la hepatitis B o C. Para comparar la persistencia entre ambas estrategias se realizo un analisis de supervivencia de Kaplan-Meir y se aplico el metodo de log-rank. Se realizo un analisis de regresion de Cox para identificar los factores predictores de persistencia. Resultados: Se incluyeron 244 pacientes, 176 con STR y 68 con LDR. El 34,1% (n = 60) de los pacientes que recibieron un regimen STR abandonaron y en el LDR el 19,1% (n = 13). Los efectos adversos fueron la principal causa de abandono del tratamiento en los pacientes que recibieron STR y el fallo virologico en el regimen LDR. La persistencia de las estrategias STR y LDR fue similar, no encontrandose diferencias estadisticamente significativas entre ambas. El consumo de drogas fue el unico factor predictivo asociado con una menor persistencia (HR = 2,59; p = 0,005). Conclusiones: La persistencia entre los regimenes STR y LDR fue similar, no detectandose diferencias significativas entre ambos. El consumo de drogas fue el unico factor independiente asociado con una menor persistencia del tratamiento antirretroviral. |
