Factores asociados a la no adherencia del tratamiento antirretroviral en pacientes con VIH en un hospital de Paraguay / Factors associated with non-adherence to antiretroviral treatment in a hospital of Paraguay

INTRODUCCIÓN: La terapia antirretroviral de gran actividad (TARGA) es la base del tratamiento de pacientes con infección por el virus de la inmunodeficiencia humana (VIH) y, hoy en día, la principal preocupación en relación con el control del VIH constituye la adherencia efectiva al tratamiento, para un tratamiento efectivo y una apropiada evaluación de los regímenes terapéuticos para poder realizar medidas correctivas y estratégicas. OBJETIVO: Identificar los factores asociados a la falta de adherencia al tratamiento antirretroviral en pacientes infectados con VIH que acuden al Hospital Nacional de Itauguá, septiembre 2016. MÉTODOS: Estudio observacional, analítico, corte transversal, muestreo no probabilístico de casos consecutivos. Se incluyeron 42 pacientes infectados con VIH con tratamiento antirretroviral en el Hospital Nacional de Itauguá. Se utilizó encuesta demográfica y cuestionario SMAQ para evaluar la adherencia al tratamiento, para el análisis se realizó la prueba Odds Ratio (OR) y se consideró una p<0,05 como significativa. RESULTADOS: Un total de 36 pacientes (86%) no son adherentes a su tratamiento. Se encontró una asociación significativa con presencia de efectos adversos (OR: 8,29, IC95%: 1,25-54,71, p=0,044) y el olvido de la toma de la medicación durante el fin de semana (OR: 28,82, IC95%: 1,45-556,1, p=0,003). CONCLUSIÓN: La tasa de falta de adherencia al tratamiento antirretroviral de los pacientes fue alta, y los factores asociados fueron la presencia de efectos adversos y el olvido de la toma de la medicación los fines de semana.

BACKGROUND: highly active antiretroviral therapy (HAART) is the basis of treatment for patients with human immunodeficiency virus (HIV) infection and, today, the main concern regarding HIV control is effective adherence to treatment, for effective treatment and appropriate evaluation of therapeutic regimens in order to carry out corrective and strategic measures. AIM: identify the associated factors to the lack of adherence to antiretroviral treatment in HIV patients that attend to the National Hospital of Itauguá on September 2016 METHODS: observational and analytical study, transverse cut, non-probabilistic sampling of consecutive cases. The study included 42 HIV patients under antiretroviral treatment of the Itaugua National Hospital. It used a demographic questionnaire and the SMAQ test to evaluate the treatment adherence. For data analysis, it was used Odd Ratio and p<0,05 was considered as significant. RESULTS: 36 patients (86%) showed non-adherence to their treatment. It was found a significant association with adverse effects presence (OR: 8.29, IC95%: 1.25-54.71, p=0.044) and forgetting to take their medicine on weekends (OR: 28.82, IC95%: 1.45-556.1, p=0.003). CONCLUSION: the rate of non-adherence to antiretroviral treatment in patients was high, and the associated factors were the presence of adverse effects and forgetting to take the medication on weekends.

Protective effect of aspirin treatment on mouse behavior in the acute phase of experimental infection with Trypanosoma cruzi.

Chagas disease is a potentially fatal disease caused by the parasite Trypanosoma cruzi, which can in some cases affect the central nervous system. The objective was to evaluate the effect of aspirin (ASA) in the behavior of mice infected with T. cruzi during the acute phase. This was an experimental study with random assignation. Twenty four BALB/c mice were divided into four groups of six animals each as follows: only ASA (OA), ASA before infection (BI), ASA after infection (AI) and only infection (OI). The strain used for infection was M/HOM/Bra/53/Y. An ASA dose of 100 mg/kg per day was administered 72 h before infection to BI group and the same dose 48 h after infection to AI group. Mice behavior in the open field test, mortality, and brain histopathology was evaluated. Data were analyzed using ANOVA, chi square test, and Kaplan-Meier with long-rank for survival analysis. In the open field test, the OA group has similar results with the BI group, in the variables of immobility and escape. Also, the OA group displayed significantly higher rates of micturition (p < 0.001) and defecation (p < 0.001) compared to infected groups. Mortality was higher in BI group (p = 0.02). The presence of T. cruzi amastigotes were higher in brain tissues of the AI and OI groups (p = 0.008). In conclusion, the administration of ASA before infection seemed to prevent behavioral changes induced by the acute infection, but it led to accelerated mortality. The study highlighted the potential importance of the pathways inhibited by ASA in the early hours of acute infection with T. cruzi.
