Potentially inappropriate medications according to Marc, STOPP and PRISCUS criteria in a cohort of elderly HIV+ patients. The COMMPI project.

OBJECTIVE: The objective is to determine the prevalence of potentially inappropriate drugs according to the Marc, STOPP, and PRISCUS lists in elderly HIV patients. METHODS: It was an observational, retrospective, and multicenter study. People living with HIV 65 years or older who underwent chronic concomitant treatment were included. Descriptive and multivariate analyzes were performed to study the association between polypharmacy and potentially inappropriate medication compliance. RESULTS: A total of 55 patients were included, 81.8% men and a median age of 69 years (IQR: 67-73). The median number of comorbidities was 3 (IQR: 2-5) and the most frequent pattern of multimorbidity was cardiometabolic (62.9%). The predominant antiretroviral treatment was triple therapy (65.5%). Polypharmacy was present in 70.9% of the patients and 25.5% had major polypharmacy. The most frequent polypharmacy pattern was cardiovascular (69.2%). The percentage of potentially inappropriate medications according to the Marc, STOPP and PRISCUS lists was 65.5%, 30.9% and 14.5%, respectively (p<0.001). Adjusted for age and sex, polypharmacy was not independently associated with potentially inappropriate medication compliance in any of the lists. CONCLUSIONS: Polypharmacy and potentially inappropriate medications have a high prevalence. There is great variability in the percentage according to the list applied. Age, sex, and presence of polypharmacy are not predisposing factors to the presence of potentially inappropriate medications.

Persistence to single-tablet regimen versus less-drug regimen in treatment experienced HIV-infected patients on antiretroviral therapy.

BACKGROUND: 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. OBJECTIVES: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

[New drugs in the treatment of chronic hepatitis C]. / Nuevos fármacos en el abordaje terapéutico de la hepatitis C.

OBJECTIVES: To analyze the efficacy and safety of the new direct antiviral agents (DAA) that will become the new therapeutic arsenal for the treatment of hepatitis C. METHODS: We carried out a research in the electronic database with the following criteria: phase II and III clinical trials (CT) published until February 2014. The Mesh term used was "chronic hepatitis C" and "therapy".Studies with boceprevir or telaprevir were excluded. For the analysis of efficacy, we evaluated the rate of Sustained Viral Response(SVR), and for the safety, side effects and safety-related discontinuations were analyzed. RESULTS: We included 24 CT that include associations with ribavirine(RBV) with or without peginterferon (PegINF) and associations of several DAA. The results associated of daclatasvir with PegINF and RBV have not been very successful. On the contrary, sofosbuvir presents activity in all viral genotypes . Sofosbuvir may be administered in free PegINF regimens. Around 90% of naïve patients achieve sustained virological response (RVS) and 80% in previously treated. In relation to second wave of NS3/4A protease inhibitors, simeprevir has achieved RVS in 90% of naïve patients and close to 80% in previously treated.The main combination of DAA were sofosbuvir and daclatasvir and sofosbuvir and ledipasvir. Both have achieved SVR in 100% of patients who previously had virological failure after receiving a protease inhibitor regimen with boceprevir or telaprevir. CONCLUSIONS: The new generation of AAD for the treatment of hepatitis C will lead to higher response rates in all subtypes of patients with lower complexity regimens and better tolerated.

Los resultados de daclatasvircon PegINF y RBV no han sido muy satisfactorios. Por el contrario,sofosbuvir es activo en todos los genotipos virales y permiteser administrado en regímenes libres de PegINF. Alrededordel 90% de los pacientes naïve alcanzan respuesta viralsostenida (RVS) , y no llegan al 80% en pretratados. En cuantoa la segunda generación de IP NS3/4A, destacar a simeprevir,con respuestas próximas al 90% en pacientes naïve y cercanasal 80% en pretratados. Entre las combinaciones de AAD evaluadas,sofosbuvir y daclatasvir y sofosbuvir y ledipasvir alcanzanel 100% de respuesta en no respondedores a triple terapiacon boceprevir y telaprevir.Conclusiones: Las nuevas generaciones de AAD frente al VHCvan a suponer un aumento de las tasas de curación en todoslos subtipos de pacientes, a través de regímenes más sencillosy mejor tolerados.
