[Translated article] Real-world persistence with dolutegravir/lamivudine versus bictegravir/emtricitabine/tenofovir-alafenamide among persons with HIV.

OBJETIVES: The main objective was to compare the persistence between dolutegravir/lamivudine (DTG/3TC) and bictegravir/emtricitabine/tenofovir-alafenamide (BIC/FTC/TAF) and to analyze reasons for discontinuation. METHODS: We conducted a retrospective, non-interventional, descriptive, and longitudinal study. All human immunodeficiency virus (HIV) patients over 18 years treated with DTG/3TC or BIC/FTC/TAF in our center were included. Persistence after first year was compared using the χ2 test. Kaplan-Meier survival analysis was performed. RESULTS: Three hundred fifty-eight patients were included. 99.5% versus 90.99% of patients were persistent after the first year for DTG/3TC and BIC/FTC/TAF respectively (p=.001). Persistence with DGT/3TC was 1237 days (IC95% 1216-1258) and persistence with BIC/FTC/TAF was 986 days [(IC95% 950-1021); p<.001]. The difference was remained after adjusting for covariates with the cox regression model [HR=8.2 (IC95% 1.03-64.9), p=.047]. The main reasons for discontinuation for BIC/FTC/TAF were toxicity/tolerability. CONCLUSION: In our study, patients have a high persistence. Patients on DTG/3TC treatment are more persistent compared to BIC/FTC/TAF, although BIC/FTC/TAF have worse baseline characteristics. The main reason for discontinuation of BIC/FTC/TAF is tolerability/toxicity.

Analysis of antiretroviral therapy interruption in people living with HIV during the 2010-2021 Period. / [Artículo traducido] Análisis de la interrupción de la terapia antirretroviral en personas que viven con VIH/sida durante el periodo 2010­2021.

OBJECTIVE: In the context of the advancement of antiretroviral therapy and, as the characteristics of people living with HIV progress toward an aging population, understanding the causes of treatment interruption becomes crucial. The aim of the study was to determine the change in reasons for antiretroviral treatment discontinuation for 12 years. Secondarily, compare annual antiretroviral regimen discontinuation rate and factors associated. METHODS: We conducted an analysis using data from people living with HIV who were receiving antiretroviral therapy and discontinued it for any reason. The study included people with HIV infection who visited an outpatient hospital pharmacy clinic from January 2010 to December 2021. Two periods were differentiated for the analysis: 2010-2015 and 2016-2021. The reasons for antiretroviral treatment discontinuation followed classification described by Swiss cohort. In the context of this study, it is pertinent to note that the term 'interruption' will be consistently used in this article to refer to the act of switching or stopping antiretroviral treatment. To examine factors associated with antiretroviral therapy discontinuation, we utilized Kaplan-Meier methods and Cox proportional models. RESULTS: We included 789 people living with HIV, predominantly male (81,5%). The main reason for discontinuation was clinical decision (50.2%) followed by adverse effects (37.9%). Focusing on clinical decision, we observed a trend change that went from antiretroviral treatment simplification regimen (56.1%) in the first part of the period analyzed to the therapeutic optimization (53.6%) in the second half. Furthermore, factors that were statistically significantly associated with antiretroviral treatment discontinuation were people with HIV ≥50 years (HR 1.60; 95%CI 1.25-2.04), post-discontinuation single-tablet regimen (HR 1.49; 95%CI 1.06-2.11) and antiretroviral drug classes. CONCLUSIONS: Over the 12 years there has been a change in the main cause of antiretroviral treatment discontinuation, currently therapeutic optimization being the main reason. Integrase inhibitors-based regimens and singletablet regimen strategies were less likely to be discontinued than others antiretroviral drug classes, allowing for better clinical management due to the efficacy profile, especially in people living with HIV ≥50 years with comorbidities.

Situación epidemiológica de VIH a nivel global y nacional: Puesta al día / Epidemiological situation of HIV at global and national level: update

INTRODUCCIÓN: En las cuatro décadas de la epidemia por VIH, se han observado avances notables que han contribuido a una disminución progresiva en la incidencia de nuevas infecciones y en la mortalidad a nivel mundial. Sin embargo, no ha ocurrido lo mismo en Latinoamérica y en Chile. OBJETIVO: Esta revisión tiene como objetivo conocer la epidemiología actual a nivel global, latinoamericano y chileno. METODOLOGÍA: Se analizaron los informes epidemiológicos oficiales de infección por VIH emitidos por organismos nacionales e internacionales, más los estudios epidemiológicos nacionales. RESULTADOS: Se estima que 39 millones de personas viven con VIH en el mundo; no obstante, la mortalidad y la incidencia de nuevos casos han disminuido de forma notoria durante las últimas dos décadas, asociado a una expansión en al acceso a terapia antirretroviral en forma global. A diferencia del resto del mundo, América Latina presenta una tendencia de alza en las nuevas infecciones y Chile registra un aumento de 35% en nuevos casos durante los últimos 10 años, coincidiendo con un aumento en los flujos de migrantes que ha afectado a la región. Algunas estrategias preventivas como la profilaxis pre exposición se han implementa-do a un ritmo lento, tanto a nivel mundial, como latinoamericano. CONCLUSIONES: La epidemiología del VIH presenta características propias regionales y nacionales. En particular en Chile, diversos factores incluyendo déficit en políticas públicas de prevención y los recientes flujos migratorios han modelado nuestra actual epidemia. El desafío presente debe contemplar los esfuerzos multisectoriales para lograr los objetivos de ONUSIDA en esta década.

BACKGROUND: Over the course of the last four decades of global HIV epidemic, significant improvements have contributed to gradually reduce the frequency of new infections and global mortality rates. However, in Latin America particularly in Chile, new infections continue increasing. AIM: This review aims to comprehend the_epidemiology today on a worldwide, Latin American, and Chilean scale. METHODS: National epidemiology studies and official HIV reports from international and national organizations were reviewed. RESULTS: It is estimated that 39 million people live with HIV worldwide; however, mortality and the incidence of new cases have decreased markedly over the last two decades, associated with an expansion in access to antiretroviral therapy globally. In contrast to the rest of the world, Latin America shows an upward trend in new infections, with Chile registering a 35% increase in new cases over the last 10 years, coinciding with an increase in migratory flows that has occurred throughout the region. Some preventive strategies, such as pre-exposure prophylaxis, have been implemented at a slow pace, both globally and in Latin America. CONCLUSIONS: The epidemiology of HIV has regional and national characteristics. Specifically in Chile, several factors, including deficits in public prevention policies and recent migratory flows, have shaped our current epidemic. The present challenge must contemplate multisectoral efforts to achieve the UNAIDS objectives during this decade.

Avances en el tratamiento de los niños y adolescentes con infección por HIV / Advances in the treatment of children and adolescents with HIV infection

El uso de antirretrovirales (ARV) en el embarazo, el parto y el recién nacido y la aplicación de tratamientos combinados en los niños se han asociado con una disminución del sida en pediatría y el aumento de la sobrevida. La introducción de los inhibidores de integrasa en una dosis diaria ha eliminado barreras para la adherencia, pero los medicamentos orales diarios continúan planteando problemas de privacidad y estigma. Las nuevas tecnologías de administración de los medicamentos y las nuevas drogas junto con la combinación de ARV y los anticuerpos ampliamente neutralizantes (bNAb), ofrecen un potencial de opciones futuras para el tratamiento pediátrico del HIV. Los bNAb son anticuerpos que pueden reconocer diferentes tipos de HIV, bloquear su entrada en las células sanas y ayudar a destruir las células ya infectadas, pueden administrarse por vía parenteral y constituyen un enfoque novedoso y seguro con potencial para el tratamiento y la prevención del HIV, incluida la transmisión vertical. En los lactantes que contraen HIV, los bNAb podrían ofrecer ventajas terapéuticas al reducir el reservorio del virus, mejorar la inmunidad adquirida y, en el futuro, proporcionar un camino hacia la cura funcional. Dentro de los ARV inyectables de acción prolongada, cabotegravir/ rilpivirina se ha incorporado en las guías internacionales de adultos y adolescentes tanto para el tratamiento como para la prevención. A medida que el tratamiento del HIV en adultos va evolucionando, es fundamental asegurar que los neonatos, lactantes, niños y adolescentes tengan acceso a las mejores opciones de tratamiento y prevención a lo largo de su vida (AU)

The use of antiretrovirals (ARVs) during pregnancy, delivery, and in the newborn and the use of combination therapy in children have been associated with a decrease in pediatric AIDS and increased survival. The introduction of once-daily integrase inhibitors has removed barriers to adherence, but daily oral medications continue to pose privacy and stigma issues. New drug delivery technologies and new drugs along with the combination of ARVs and broadly neutralizing antibodies (bNAbs) offer potential future options for pediatric HIV treatment. bNAbs are antibodies that can recognize different types of HIV, block their entry into healthy cells and help destroy already infected cells, can be delivered parenterally, and represent a novel and safe approach with potential for the treatment and prevention of HIV, including mother-to-child transmission. In infants who contract HIV, bNBAs could offer therapeutic advantages by reducing the viral reservoir, enhancing acquired immunity and, in the future, providing a pathway to a functional cure. Within the long-acting injectable ARVs, cabotegravir/rilpivirine has been incorporated into international guidelines for adults and adolescents for both treatment and prevention. As adult HIV treatment evolves, it is critical to ensure that newborns, infants, children and adolescents have access to the best treatment and prevention options throughout their lives (AU)

Aplicación de un modelo farmacocinético poblacional para el seguimiento de pacientes en tratamiento con dolutegravir: estudio piloto

Introducción: a pesar de los avances en tratamiento antirretroviral, existe la posibilidad de que personas que viven con el virus de la inmunodeficiencia humana (VIH) experimenten falla terapéutica vinculada a múltiples factores que impactan en la respuesta al fármaco. Objetivos: evaluar la utilidad de aplicar un modelo farmacocinético en pacientes con diagnóstico de VIH en tratamiento con dolutegravir para el análisis de las concentraciones plasmáticas experimentales. Adicionalmente, se pretende identificar potenciales interacciones farmacológicas, evaluar adherencia y fallo terapéutico. Material y método: se realizó un estudio piloto transversal y observacional en pacientes VIH tratados con dolutegravir que incluyó la dosificación de la concentración plasmática, evaluación de adherencia mediante el cuestionario simplificado de adherencia a la medicación (SMAQ) y retiro de medicación. Se utilizó un modelo poblacional referenciado en la bibliografía para la predicción de concentraciones de dolutegravir en cada paciente y se compararon con las concentraciones experimentales. Resultados: fueron incluidos en el estudio 21 pacientes. Al cotejar las concentraciones plasmáticas experimentales con la simulación farmacocinética se encontraron diferencias para 12 pacientes, las cuales se explican por posibles interacciones farmacológicas, mala adherencia u otros factores que afectan la farmacocinética. Se detectó 38% de no adherencia de acuerdo con SMAQ y 23% de acuerdo con el retiro de medicación. Conclusiones: se expone el rol potencial de los modelos farmacocinéticos para la interpretación de concentraciones plasmáticas y se genera la necesidad de avanzar en este tipo de estudios para el establecimiento de rango terapéutico y aplicabilidad clínica.

Introduction: Despite advances in antiretroviral treatment, there is a possibility that people living with HIV may experience treatment failure linked to multiple factors that impact drug response. Objective: To evaluate the usefulness of applying a pharmacokinetic model in patients diagnosed with HIV undergoing treatment with dolutegravir for the analysis of experimental plasma concentrations. Additionally, the aim is to identify potential drug interactions, assess adherence, and therapeutic failure. Method: A cross-sectional, observational pilot study was conducted in HIV patients treated with dolutegravir, which included plasma concentration dosing, assessment of adherence using the Simplified Medication Adherence Questionnaire (SMAQ), and medication withdrawal. A population-based model referenced in the literature was used to predict dolutegravir concentrations in each patient and these were compared with experimental concentrations. Results: Twenty-one patients were included in the study. When comparing experimental plasma concentrations with pharmacokinetic simulation, differences were found for 12 patients, which can be explained by possible drug interactions, poor adherence, or other factors affecting pharmacokinetics. Non-adherence was detected in 38% according to the SMAQ and 23% according to medication withdrawal. Conclusions: The potential role of pharmacokinetic models in the interpretation of plasma concentrations is highlighted, emphasizing the need to advance in this type of studies to establish therapeutic ranges and clinical applicability.

[Epidemiology, treatment and prognosis of HIV infection in 2024: A practical review]. / Epidemiología, tratamiento y pronóstico de la infección VIH en 2024: revisión práctica.

In recent years, the epidemiology and prognosis of HIV infection have undergone significant changes thanks to the recommendation of antiretroviral therapy (ART) for all infected persons, the development of more effective and better tolerated drugs, and preventive measures such as pre-exposure prophylaxis (PrEP). The evolution of ART, now with simple oral and injectable options, has also contributed to improvements in comprehensive HIV treatment and care. With early diagnosis and early initiation of ART, the life expectancy of people with HIV has reached the same as the general population. However, many people with HIV remain undiagnosed or are diagnosed late, and some population groups experience greater vulnerability, affecting individual and collective health. In this review we review the current epidemiology, treatment and prognosis of HIV infection.

Factores asociados a la mala adherencia al tratamiento antirretroviral en pacientes VIH positivo

Introducción: La infección por el virus de inmunodeficiencia humana representa un problema de salud pública en el mundo. La adherencia a la terapia antirretroviral es necesaria para alcanzar un estado de supresión viral máxima y disminuir la tasa de infecciones oportunistas. Sin embargo, diversos son los factores que pueden influir en la adherencia terapéutica. Objetivo: Identificar los factores de riesgo asociados a la mala adherencia a la terapia antirretroviral en pacientes con el virus de inmunodeficiencia humana. Métodos: Se empleó un estudio con diseño observacional, analítico, de tipo casos y controles. El tamaño muestral fue de 276, a partir del cual 138 fueron casos y 138 controles. Los datos recolectados fueron analizados utilizando métodos de estadística descriptiva y estadística inferencial. Resultados: El análisis multivariado determinó una asociación estadísticamente significativa entre la variable adherencia al tratamiento antirretroviral y las variables depresión (odds ratio OR ajustado= 2,15), esquema de terapia antirretroviral alternativo (OR ajustado= 2,40), efectos secundarios (OR ajustado= 4,24) y cambio en la adherencia durante el estado de emergencia (OR ajustado= 5,67), independientemente de las otras variables intervinientes. Conclusiones: La depresión, el uso del esquema de terapia antirretroviral alternativo, la presencia de efectos secundarios a terapia antirretroviral y el cambio en la adherencia durante el estado de emergencia aumentan el riesgo de mala adherencia a la terapia antirretroviral.

Introduction: Human immunodeficiency virus infection represents a public health public problem in the world. Adherence to antiretroviral therapy is necessary to achieve a state of maximum viral suppression and decrease the rate of opportunistic infections. However, there are several factors that can influence therapeutic adherence. Objective: To identify the risk factors associated with poor adherence to antiretroviral therapy in patients with the human immunodeficiency virus. Methods: A study with an observational, analytical, case-control type design was used. The sample size was 276, from which 138 were cases and 138 controls. The collected data was analyzed using methods of descriptive statistics and inferential statistics. Results: The multivariate analysis determined a statistically significant association between the variable adherence to antiretroviral treatment and the variables depression (adjusted Odds Ratio OR = 2.15), alternative antiretroviral therapy scheme (adjusted OR= 2.40), side effects (adjusted OR= 4.24), and change in adherence during the state of emergency (adjusted OR= 5.67) independently of the other intervening variables. Conclusions: Depression, the use of alternative antiretroviral therapy regimens, the presence of side effects to antiretroviral therapy, and the change in adherence during the state of emergency increase the risk of poor adherence to antiretroviral therapy.

Síndrome inflamatorio de reconstitución inmunológica (SIRS) en la salud reproductiva / Immune reconstitution inflammatory syndrome (IRIS) in reproductive health

Resumen El embarazo es un proceso que genera grandes cambios inmunitarios en los cuales participan los linfocitos T con respuestas proinflamatorias (Th1/Th17) y antiinflamatorias (Th2/Treg), con la finalidad de mantener el óptimo estado y desarrollo fetal. En la infección por VIH estos ambientes inmunológicos son afectados directamente con el descenso de las células TCD4. El uso de antirretrovirales (ART) ha permitido que las mujeres que viven con VIH puedan disminuir de manera importante la posibilidad de infectar a sus productos con el virus. El embarazo, enfermedades autoinmunes y el uso de ART son factores conocidos para el desarrollo del síndrome inflamatorio de reconstitución inmunológica debido a la recuperación abrupta de la respuesta inmunitaria. En esta revisión describimos parte de estos cambios en el embarazo y puerperio sin patología añadida, además proponemos un posible comportamiento en los perfiles Th1/Th2 en mujeres que viven con VIH que reciben ART y cursan el primer año posparto.

Abstract Pregnancy is a process which generate great immunologic changes with participation of T lymphocytes with inflammatory (Th1/Th17) and anti-inflammatory response (Th2/Treg), with the purpose of maintain the optimum condition and fetal development. In HIV infection this immunological ambient are affected directly due the decrease of T CD4 cells. The use of antiretrovirals (ART) has allowed that women living with HIV can decrease the possibility to infect their newborns with the virus. The pregnancy, autoimmune diseases, and the use of ART are known factors for the progress of immune reconstitution inflammatory syndrome due to the abrupt recovery of immune response. In this review we describe some of these changes during the pregnancy and puerperium without any disease added, furthermore we propose a possible behavior of Th1/Th2 profile in women who live with HIV and receive ART during the first year of postpartum.

Aspectos farmacológicos y adherencia al tratamiento antirretroviral en pacientes VIH

Introducción: La adherencia al tratamiento farmacológico favorece la supresión viral y reduce la resistencia a la terapia antirretroviral de gran actividad a largo plazo. Objetivo: Determinar la relación entre los aspectos farmacológicos y la adherencia al tratamiento antirretroviral de una IPS colombiana. Metodología: Estudio analítico transversal en pacientes con diagnóstico de VIH en tratamiento antirretroviral entre los años 2012 a 2020. Se utilizó un modelo de regresión logística binaria múltiple con fines explicativos. Resultados: Se analizaron 9835 pacientes donde la proporción de adherencia fue de 90 % y en el modelo ajustado se evaluó su relación con los antecedentes de no adherencia (ORa:0,52 IC95 °/o:0,40-0,66), grupo farmacológico (2 ITIAN + 1 IP u otro) (ORa:1,22 IC95 %:0,99-1,76), dos tomas al día (ORa:1,02 IC95 %:0,74-1,40), unidades al día (≥ 3) (ORa:0,69 IC95 %:0,47-1,02), reacciones adversas a medicamentos (ORa:0,56 IC95 °%:0,40-0,78), polimedicación (ORa:1,36 IC95 %:1,00-1,85), tiempo TAR (1 a 2 años) (ORa:1,63 IC95 %:1,27-2,09),tiempo TAR (6 a 12 meses) (ORa:1,66 IC95 %:1,27-2,18), tiempo TAR (<6 meses) (ORa:1,36 IC95 %:1,03-1,78), tasa de reclamación de los medicamentos (ORa:0,42 IC95 %:0,32-0,55) y antecedentes PRUM (ORa:0,11 IC95 %:0,09-0,14). Discusión: La proporción de adherencia obtenida es superior a lo descrito para otros países (entre 60-77 %); sin embargo se encuentra que los hallazgos correspondientes al efecto de las variables farmacológicas analizadas son acordes a lo descrito en estudios previos en el tema Conclusión: Los antecedentes de no adherencia, reacciones adversas, tasa de reclamación de los medicamentos y antecedentes de problemas relacionados con el uso de medicamentos son aspectos que reducen la probabilidad de adherencia; mientras que el mayor tiempo de uso del tratamiento aumenta la misma.

Introduction: Adherence to drug treatment promotes viral suppression and reduces long-term resistance to highly active antiretroviral therapy (HAART). Objective: To determine the relationship between the pharmacological aspects and adherence to antiretroviral treatment in a Colombian IPS. Methodology: Cross-sectional analytical study in patients with HIV on antiretroviral treatment between 2012 and 2020. A multiple binary logistic regression model was used for explanatory purposes. Results: A total of 9,835 patients were analyzed where the proportion of adherence was 90 % and in the adjusted model its relationship with history of non-adherence was assessed (ORa: 0,52 95 % CI: 0,40-0,66), pharmacological group (2 NRTI + 1 PI or other) (ORa: 1,22 95 % CI: 0,99-1,76), two doses per day (ORa: 1,02 95 % CI: 0,74-1,40), units per day (≥ 3 ) (ORa: 0,69 95 % CI: 0,47-1,02), adverse drug reactions (ORa: 0,56 95 % CI: 0,40-0,78), polypharmacy (ORa: 1,36 95 % CI : 1,00-1,85), ART time (1 to 2 years) (ORa: 1,63 95 % CI: 1,27-2,09), ART time (6 to 12 months) (ORa: 1,66 95 % CI: 1,27-2,18), ART time (<6 months) (ORa: 1,36 95 % CI: 1,03-1,78), inconsistency in the claim (ORa: 0,42 95 % CI: 0,32-0,55) and PRUM history (ORa: 0,11 95 % CI: 0,09-0,14). Discussion: The proportion of adherence obtained is higher than that described for other countries (between 60-77 %); however, the findings corresponding to the effect of the pharmacological variables analysed are in line with those described in previous studies on the subject. Conclusion: The history of non-adherence, adverse reactions, inconsistencies in the claim fill history and problems related to the use of medications are aspects that reduce the probability of adherence. While the longer time of use of the treatment increases adherence.

Evolución temporal de la terapia antirretroviral (2017-2021): análisis de la modificación del tratamiento y su impacto económico / Temporal evolution of antiretroviral therapy (2017-2021): analysis of treatment change and its economic impact

Objetivos. Analizar las modificaciones de la terapia antirre troviral (TAR) y su impacto económico en la práctica clínica diaria. Material y métodos. Estudio observacional, retrospectivo de los pacientes que iniciaron TAR entre 01/2017-12/2021 (se guimiento hasta 12/2022). Variables recogidas: TAR, duración, motivo del cambio y costes del tratamiento. Resultados. 280 pacientes iniciaron TAR. La mediana de durabilidad de la 1ª línea fue: 19,9 meses en 2017 (IC95% 13,9-25,9), 12,2 meses en 2018 (IC95% 4,7-19,7), 27,4 meses en 2019 (IC95% 6,8-48,1) y no se alcanzó la mediana para los años 2020 y 2021 (p p<0,001). De un total de 541 líneas prescri tas, la triple terapia con inhibidores de la proteasa se modificó en el 63,8% (81/127), seguido de los inhibidores de la integrasa 52,1% (159/305), mientras que, la terapia dual (DTG/3TC) solo en el 8,3% (7/84). De un total de 261 modificaciones, la simpli ficación/optimización 47,5% (124/261) fue el principal motivo, seguido de efectos adversos 21,8% (57/261), siendo el 2017 el único año donde ambos motivos se encontraban al mismo nivel. El impacto económico de los cambios supusieron una re ducción del coste medio de 34,0€ [-391,4 a +431,4] al mes/ paciente. El año 2019 es el único año donde estos cambios se asociaron con un incremento del coste adicional medio (23,4€ [-358,3 a +431,4]). Conclusiones. Dejando atrás el fracaso virológico, la sim plificación a regímenes de un solo comprimido y de mayor tolerancia han marcado la nueva la era TAR. Con un impacto económico que, a pesar del punto de inflexión del 2019, refleja una reducción progresiva de costes mantenida en el tiempo (AU)

Objectives. To analyze the modifications of antiretrovi ral therapy (ART) and their economic impact on daily clinical practice. Material and methods. Observational, retrospective study of patients who started ART between 01/2017-12/2021 (follow-up until 12/2022). Variables collected: prescribed ART, duration, the reason for the change, and treatment costs. Results. A total of 280 patients initiated ART therapy. The median durability of 1st line was: 19.9 months in 2017 (95%CI 13.9-25.9), 12.2 months in 2018 (95%CI 4.7-19.7), 27.4 months in 2019 (95%CI 6.8-48.1) and the median was not reached for the years 2020 and 2021 (p<0.001). Triple therapy with protease inhibitors was changed in 63.8% (81/127) of cases, followed by integrase inhibitors 52.1% (159/305), while dual therapy (DTG/3TC) only in 8.3% (7/84). The main cause of dis continuation was simplification/optimization 47.5% (124/261), followed by adverse effects 21.8% (57/261), with 2017 being the only year where simplification/optimization was at the same level as adverse effects. The economic impact of ART changes resulted in an average cost reduction of 34.0€ [-391.4 to +431.4] per month per patient. The year 2019 stands out as the only year where these changes were associated with an increase in mean additional cost (23.4€ [-358.3 to +431.4]). Conclusions. Optimization/simplification accounts for almost half of the reasons for TAR change, with an econom ic impact that, despite the inflection point of 2019, each year manages to exceed the previous one, achieving a progressive cost reduction maintained over time (AU)

Asociación entre el miedo al COVID-19 y la adherencia al tratamiento antirretroviral en personas con VIH-SIDA

Introducción. Una de las consecuencias psicológicas más frecuentes del COVID-19 es el miedo. Éste podría ocasionar una adherencia terapéutica no óptima y permitir la progresión de la enfermedad en personas con VIH. Objetivo. Evaluar la asociación entre el miedo a contraer COVID-19 y la adherencia al tratamiento antirretroviral en personas con VIH entre la tercera y cuarta ola epidémica de COVID-19 en el Perú. Métodos. Estudio transversal analítico en adultos con VIH del centro especializado Vía Libre enrolados por muestreo no probabilístico. Se empleó la escala Fear of COVID-19 Scale para medir el miedo a contraer COVID-19, y el cuestionario SMAQ para evaluar la adherencia terapéutica. Los resultados se presentaron de forma descriptiva, usando chi cuadrado para el análisis bivariado y modelos lineales generalizados familia Poisson para estimar razones de prevalencia crudas y ajustadas (RPa). Resultados. Entre febrero - julio del 2022, se enrolaron 149 personas con una mediana de edad de 35 años, el 91,3% fueron varones, y el 75,2% con carga viral indetectable. No se halló asociación entre el miedo a contraer COVID-19 y la adherencia terapéutica (RPa: 0,99; IC95%: 0,97 a 1,02). Adicionalmente, encontramos que las personas que presentaban alguna comorbilidad fueron 89% más adherentes que los que no las presentaban (RPa: 1,89; IC95%: 1,52 a 2,35). Conclusión. El miedo a contraer COVID-19 no se asoció a la adherencia al TARGA durante la tercera ola de pandemia en el Perú. Sin embargo, el presentar alguna comorbilidad se asoció a una adherencia terapéutica óptima. Se debe poner énfasis en los posibles factores que afecten la adherencia en personas con VIH durante la pandemia por COVID-19.

Introduction. One of the most frequent psychological consequences of COVID-19 is fear, which could lead to non-optimal therapeutic adherence and, therefore, to the disease progression. Objectives. To evaluate the possible association between the fear of contracting COVID-19 and adherence to antiretroviral therapy in persons with HIV during the period between the third and fourth epidemic wave of COVID-19 in Peru. Methods. Analytical cross-sectional study in adults with HIV from the specialized center "Vía Libre" enrolled by non-probabilistic sampling. The validated "Fear of COVID-19 Scale" was used to measure the fear of getting sick from COVID-19, and the "SMAQ" questionnaire to assess therapeutic adherence. Results were presented descriptively, using chi-square for bivariate analysis and generalized linear models, Poisson family to calculate crude and adjusted prevalence ratios (aPR). Results. Between February and July of 2022, 149 adults with a median age of 35 years were enrolled, 91.3% being male, and 75,2% had undetectable viral load levels. No association was found between fear of contracting COVID-19 and HAART adherence (aPR: 0,99; 95% CI 0,97 to 1,02). Persons with a comorbidity were 89% more adherent than persons withoutcomorbidities (RPa: 1,89; 95% CI 1,52 to 2,35). Conclusion. The fear of contracting COVID-19 was not associated with adherence to HAART during the third wave of COVID-19 pandemic in Peru. However, presenting a comorbidity was associated with optimal HAART adherence. Emphasis should be placed on potential factors affecting medication adherence in people with HIV during the COVID-19 pandemic.

Survival of patients living with HIV and cancer in Cali, Colombia

Background: People living with HIV have an increased risk of cancer compared to the general population. However, with the increase in life expectancy and advances in antiretroviral therapy, the survival of patients with cancer and HIV has changed. Objective: To determine the survival of patients living with HIV and cancer in Cali, Colombia Methods: A retrospective cohort study was conducted at the Fundación Valle del Lili, Cali, Colombia. Data from the HIV database was crossed with data from the hospital and population-based cancer registries between 2011-2019. Patients <18 years, limited available clinical information on the diagnosis and treatment of HIV and cancer, and non-oncological tumor diagnosis were excluded. Results: A total of 173 patients were included. The frequencies of AIDS-defining neoplasms were: Non-Hodgkin lymphoma (42.8%), Kaposi sarcoma (27.8%), and cervical cancer (4.6%). Overall survival was 76.4% (95% CI 68.9-82.3) at five years. Poorer survival was found in patients with AIDS-defining infections (56.9% vs. 77.8%, p=0.027) and non-AIDS-defining infections (57.8% vs. 84.2%, p=0.013), while there was better survival in patients who received antiretroviral therapy (65.9% vs. 17.9%, p=0.021) and oncological treatment (66.7% vs. 35.4%, p<0.001). The presence of non-AIDS-defining infections increases the risk of dying (HR = 2.39, 95% CI 1.05-5.46, p=0.038), while oncological treatment decreases it (HR = 0.33, 95% CI 0.14-0.80, p=0.014). Conclusions: In people living with HIV, Non-Hodgkin lymphoma and Kaposi sarcoma are the most common neoplasms. Factors such as AIDS-associated and non-AIDS-associated infections have been identified as determinants of survival. Cancer treatment seems to improve survival.

Antecedentes: Las personas que viven con VIH tienen un riesgo mayor de cáncer en comparación con la población general. Sin embargo, con el aumento de la esperanza de vida y los avances en la terapia antirretroviral, la supervivencia de los pacientes con cáncer y VIH ha cambiado. Objetivo: Determinar la supervivencia de los pacientes que viven con VIH y cáncer en Cali, Colombia. Métodos: Se realizó un estudio de cohorte retrospectivo en la Fundación Valle del Lili, Cali, Colombia. Los datos de la base de datos de VIH se cruzaron con los datos de los registros de cáncer de base hospitalaria y poblacional entre 2011-2019. Se excluyeron los pacientes <18 años, con información clínica limitada disponible sobre el diagnóstico y tratamiento del VIH y el cáncer y los casos con diagnóstico de tumor no oncológico. Resultados: Se incluyeron un total de 173 pacientes. Las frecuencias de neoplasias definitorias de SIDA fueron: linfoma no Hodgkin (42.8%), sarcoma de Kaposi (27.8%) y cáncer cervical (4.6%). La supervivencia global fue del 76.4% (IC 95% 68.9-82.3) a los cinco años. Se encontró una peor supervivencia en pacientes con infecciones definitorias de SIDA (56.9% vs. 77.8%, p=0.027) e infecciones no definitorias de SIDA (57.8% vs. 84.2%, p=0.013), mientras que hubo una mejor supervivencia en pacientes que recibieron terapia antirretroviral (65.9% vs. 17.9%, p=0.021) y tratamiento oncológico (66.7% vs. 35.4%, p<0.001). La presencia de infecciones no definitorias de SIDA aumentó el riesgo de morir (HR = 2.39, IC 95% 1.05-5.46, p=0.038), mientras que el tratamiento oncológico lo disminuyó (HR = 0.33, IC 95% 0.14-0.80, p=0.014). Conclusiones: En las personas que viven con VIH, el linfoma no Hodgkin y el sarcoma de Kaposi son las neoplasias más comunes. Se han identificado factores como las infecciones asociadas al SIDA y las infecciones no asociadas al SIDA como determinantes de la supervivencia. El tratamiento del cáncer parece mejorar la supervivencia.

Intervenciones psicológicas para mejorar la adherencia al tratamiento antirretroviral: Revisión sistemática y metaanálisis / Psychological interventions to improve adherence to antiretroviral treatment: Systematic review and meta-analysis

Resumen El VIH es una enfermedad crónica que afecta a los receptores CD4 del sistema inmunológico. El Tratamiento Antirretroviral (TARV) es vital para disminuir la carga viral, pero su éxito depende del grado de adherencia al mismo. El objetivo de este estudio fue revisar los factores asociados a la eficacia de las intervenciones psicológicas para incrementar la adherencia al TARV y agregar los hallazgos en estimaciones cuantitativas de su impacto en la adherencia. La revisión de la literatura fue realizada desde agosto de 2017 hasta abril de 2020 en PubMed, EBSCO y Springer Link, utilizando los siguientes criterios de elección de los estudios: (1) que estuvieran publicados en revistas indexadas con revisión por pares, (2) que fueran experimentales o cuasiexperimentales, (3) que emplearan técnicas para el incremento de la adherencia, (4) que estuvieran publicados en español o inglés, (5) que reportaran los estadísticos necesarios para el cálculo del tamaño de efecto. De los 15 estudios seleccionados (. total = 1669), se obtuvieron 38 tamaños del efecto. El cálculo de los tamaños de efecto individuales y global se realizó usando el programa Comprehensive Meta-Analysis (Biostat, 2011, v. 2.2.064). Todos los tamaños de efecto fueron calculados usando la diferencia estandarizada de medias y un modelo de efectos aleatorios. El tamaño de efecto global fue moderado (. = 0.56, . = 38, IC95 % = 0.39 - 0.72, . < .001), mostrando que las intervenciones fueron significativamente superiores al grupo de comparación. Debido a la alta heterogeneidad de los estudios (I. = 82.25), se analizaron 12 variables moderadoras, de las cuales 11 fueron significativas (. < .005). Los resultados del análisis de variables moderadoras indican un mayor efecto en el incremento de la adherencia al TARV en intervenciones con marcos teóricos basados en el apoyo social por pares y con metodologías adaptables a la vivencia cotidiana de la persona.

Abstract HIV is a chronic disease that affects the CD4 receptors of the immune system, so it is necessary for people with the virus to be under Antiretroviral Treatment (ART) to reduce the viral load in the body. The success of ART is related to adherence to treatment, understood as: the intake of antiretroviral drugs, follow-up of medical controls and implementation of healthy lifestyles. There are personal, social and health systems problems that prevent people from adhering to ART in an adequate way. This situation has become a public health problem because inappropriate taking of drugs often leads to drug resistance. In this way, it is necessary to implement effective psychological interventions aimed at increasing adherence to ART, to contribute to a better use of antiretrovirals and to the improvement of the quality of life of people with HIV. Accordingly, the objective was to review the factors associated with the efficacy of psychological interventions, to increase adherence to ART and to aggregate the findings in quantitative estimates of its impact on adherence. For this purpose, meta-analysis was used as a research technique that allows a quantitative analysis of results by calculating specific statistics. The literature search and review were carried out from August 2017 to May 2019 in the PubMed, Academic Search Complete (EBSCO Host) and Springer Link databases, for the identification of experimental studies that met the eligibility criteria (studies published in peer-reviewed indexed journals, experimental or quasi-experimental research, using techniques to increase adherence, published in Spanish and English and reporting the necessary statistics for effect size calculation). Of the 15 studies (total n = 1669) selected, 38 effect sizes were obtained. The calculation of the individual and global effect size was performed using the Comprehensive Meta-Analysis software (Biostat, 2011, v. 2.2.064). All the effect sizes were calculated using the standardized mean difference and a random effects model. To find out if individual effect sizes were homogeneous and therefore represent a similar measure of treatment efficacy, the Cochran Q homogeneity test was applied; based on this, the I. was calculated. Also, it was performed a publication bias calculation, the objective of which was to estimate the number of non-significant effect sizes that are required for a reduction of the global effect size to a smaller and non-significant one. The overall effect size was moderate (. = 0.56, . = 38, 95 % CI = 0.39 - 0.72, . < .001) and presented high heterogeneity (I. = 82.25). Twelve moderator variables were analyzed (year of publication, percentage of men, average age, measurement time, number of sessions / interactions, duration of sessions, total duration of intervention, economic remuneration for intervention, place where the intervention was carried out, type of intervention, intervention modality and adherence measurement), of which 11 were significant (all but intervention modality: individual vs. group therapy). The results suggest that the success of an intervention proposal to improve adherence to ART will be related to its ability to consider the components of the environment and the social situation in which the person with HIV develops, as well as their intrinsic characteristics in interaction with their context. Likewise, it is necessary to consider that the presence of adherence barriers should be treated specifically in young people and adults, as well as in men and women. Finally, it is more important to establish interventions aimed not only to increase adherence, but maintaining it, which is why it is considered necessary to propose studies aimed at maintaining adherence, as well as offering practical tools for people to make better decisions about their health.

Análisis de 23 pacientes con infección por VIH y Covid-19. Estudio descriptivo / Analysis of 23 patients with HIV infection and Covid-19. Descriptive study

Las características clínicas, el diagnóstico, el pronóstico, el tratamiento y la profilaxis de la infección por el coronavirus SARS-CoV-2 en los pacientes infectados por el VIH, son muy similares a los de la población general cuando estos se encuentran con supresión de la replicación viral con el tratamiento antirretroviral y tienen una cifra de linfocitos T CD4 + > de 200 células/uL. El tiempo medio de incubación es de 5 días (entre 2 y 14 días). En sujetos VIH positivos, cuánto mayor es la carga viral plasmática para VIH y el recuento de CD4 + es < 200 cél/uL, el tiempo que transcurre entre la infección por el coronavirus y la aparición de las manifestaciones clínicas es menor. En la población general, el 70-80% de individuos tienen una infección por SARS-CoV-2 leve/moderada, un 20-25% grave y un 5% muy grave que requiere internación en UTI. En los pacientes infectados por el VIH se desconoce esta proporción, aunque estudios preliminares consideran que las proporciones serían del 66%, 22% y 12%, respectivamente25. Se presenta una serie de 23 pacientes con coinfección SARS-CoV-2/VIH y se analizan las características epidemiológicas, clínicas y la evolución en relación con ambas infecciones

The clinical characteristics, diagnosis methods, medical prognosis, treatment alternatives and prophylaxis of coronavirus SARS-CoV-2 infection in HIV infected individuals are very similar in patients under HAART with undetectable viral load and CD4+ > than 200 cell/uL. The mean incubation time is of 5 days (range 2 to 14 days). In HIV-seropositive patients, with high viral load and CD4 < 200 cell/ uL, the time between infection for coronavirus and the onset of symptoms is minor. In the general population, 70% to 80% of individuals infected by SARS-CoV-2 develops a mild to moderate disease; 20% to 25% severe forms and 5% develops very severe clinical compromise that requieres intensive therapy unit income. In HIV-positive patients these percentages would be 66%, 22% y 12%, respectively25. Here we present a series of 23 HIV-seropositive patients coinfected by coronavirus SARS-CoV-2; we analyzed the epidemiology, clinical manifestations and the evolution related with both infections

Factors interfering with the production of Histoplasma capsulatum antigens / Fatores que interferem na produção de antígenos de Histoplasma capsulatum

Histoplasma capsulatum causes systemic mycosis that depends on host susceptibility, fungal virulence, and factors associated with the infectious process. We evaluated the possible interference of the phenotype of 12 samples of H. capsulatum isolated from HIV-positive and negative patients in obtaining antigens, aiming at the serological diagnosis through the gender-specific recognition of the H and M fractions. The antigens were evaluated by double immunodiffusion against H. capsulatum anti-antigen polyclonal antibody and serum samples from patients with histoplasmosis.The phenotypic evaluation revealed differences in the identification of the fungal agent and in the expression of H and M antigens, considered serological markers of the disease, associated with pigmentation and the production of conidia. It was found that antigenic preparations obtained from H. capsulatum isolated from HIV-positive patients may have satisfactory antigenic capacity. The patient's immune status does not seem to interfere with the expression of antigenic proteins secreted by H. capsulatum. However, we suggest that prolonged use of antiretrovirals drugs or steroids can cause important phenotypic alterations. We showed that some fungal samples from patients with a long history of immunosuppressive drugs produced atypical cellular elements and low reactivity against the H and M fractions. (AU)

Histoplasma capsulatum causa micose sistêmica endêmica que depende da suscetibilidade do hospedeiro, da virulência fúngica e de fatores associados ao processo infeccioso. Avaliamos a possível interferência do fenótipo de 12 amostras de H. capsulatumisolados de pacientes HIV positivos e negativos na obtenção de antígenos, visando o diagnóstico sorológico por meio do reconhecimento gênero-específico das frações H e M. Os antígenos foram avaliados por imunodifusão dupla, frente a anticorpo policlonal anti-antígeno de H. capsulatum e frente a amostras de soro de pacientes com histoplasmose. A avaliação fenotípica revelou diferenças, não só na identificação do agente fúngico, mas também na expressão dos antígenos H e M, considerados marcadores sorológicos da doença, associados à pigmentação e produção de conídios. Verificou-se que preparações antigênicas obtidas de H. capsulatum isoladas de pacientes HIV positivos podem ter capacidade antigênica satisfatória. O estado imunológico do paciente parece não interferir na expressão de proteínas antigênicas secretadas por H. capsulatum. No entanto, sugerimos que o uso prolongado de antirretrovirais e/ou esteróides pode causar alterações fenotípicas importantes. Verificou-se que algumas amostras fúngicas isoladas de pacientes com longo histórico de uso de imunossupressores produziram elementos celulares atípicos e baixa reatividade sorológica contra as frações H e M de H. capsulatum.

Infección por VIH: carga viral plasmática intratratamiento en la era del "Indetectable = Intransmisible" / HIV infection: Plasma viral load intratratization in the era of the "undetectable = non transmissible"

Se acepta que los individuos infectados por el virus de la inmunodeficiencia humana (HIV) son incapaces de transmitir la infección por vía sexual mientras sus niveles de carga viral plasmática se mantengan indetectables. Con el propósito de estudiar qué porcentaje de infectados por el HIV cumple esa condición estudiamos una población de pacientes asistidos regularmente en un hospital general de agudos de la ciudad de Buenos Aires. Se incluyeron 298 individuos, 162 de ellos de sexo masculino (54.36%) con una edad (promedio ± desvío estándar) de 47.83 ± 11.69 años y un recuento de células CD4+ de 693.93 ± 363.87 x 106 células / mL de sangre periférica. La carga viral plasmática fue indetectable en 230 de los individuos estudiados (77.81%). Los 68 restantes (22.82%) mostraron en promedio 9856.67 ± 70922.11 copias / mL, siendo estos niveles mayores en hombres que en mujeres (17379.39 ± 95521.51 copias / mL vs 895.78 ± 5952.99 copias / mL, respectivamente; p=0.015, Student t test), lo que explicaría los recuentos de linfocitos CD4+ significativamente menores hallados en hombres.187 de 231 individuos que recibían su primer tratamiento antiretroviral (TARV) mostraron cargas virales indetectables (80,95%) versus 42 de 67 pacientes que habían recibido dos o más esquemas de tratamiento antirretroviral (61,69%; p= 0.002, prueba de 2 ). Estos resultados muestran que un porcentaje importante de infectados por el HIV continúan presentando cargas virales plasmáticas detectables a pesar del TARV, siendo capaces de transmitir la infección por vía sexual a sus parejas

It is widely accepted that HIV-infected subjects are incapable to transmit sexually the infection while their plasmatic viral load remains undetectable. In order to assess the percentage of HIV infected patients showing undetectable viral loads during their antiviral treatment we studied a population of patients regularly assisted at a general hospital. A total of 298 patients (162 men; 54.36%) were admitted to the study. The mean age was (mean ± standard deviation) 47.83 ± 11.69 years, and the mean CD4+ cell count was 693.93 ± 363.87 x 106 cells / mL. These variables did not showed statistically significative differences between men and women. Plasmatic viral load was undetectable in 230 patients (77.81%). The remaining 68 patients (22.82%) showed a mean of 9856.67 ± 70922 copies / mL. These values were higher in men than in women (17379.39 ± 95521.51 copies / mL vs 895.78 ± 5952.99 copies / mL, respectively; p=0.015, Student t test). In line with these findings, CD4+ cell count was significantly lower in men (575.10 ± 345.14 cells / L vs. 707.04 ± 373.46 cells / L, respectively; p=0.0019, Student t test). 187 out of 231 patients receiving their first antiretroviral treatment showed undetectable viral loads (80,95%), while only 42 out of 67 patients having previously received other antiretroviral schemes had undetectable levels of plasmatic viral load (61,69%; p= 0.002, 2 ). These findings show that an important number of patients may keep detectable levels of plasmatic viral load during antiretroviral treatment, being therefore capable to sexually transmit the infection to their couples.

Prevalencia de glucosa alterada en ayuno y dislipidemia entre pacientes mexicanos con VIH naïve a tratamiento antirretroviral.

BACKGROUND: Metabolic complications have become more relevant in the care of patients with HIV. However, little is known about the incidence and risk factors for these disorders among HIV-infected antiretroviral treatment naïve (ARTn) patients. OBJECTIVE: To recognize the prevalence of Impaired Fasting Glucose (IFG) and dyslipidemia among HIV-infected ARTn Mexican individuals and identify associated risk factors. METHOD: A retrospective study was conducted in HIV-1-infected ART-N patients, referred for attention to a general hospital in Mexico City, between 2009 and 2019. We collected information for anthropometric, clinical, biochemical and HIV status variables. RESULTS: We included 221 patients, 97% were males, mean age 30 years (interquartile range [IQR]: 25-38); median CD4 count was 250 cells/mm3 (IQR: 120.25-391) and median log10 HIV viral load was 4.69 HIV-1 RNA copies/ml (IQR: 3.64-5.25). Prevalence of IFG was 22.6% and was associated with overweight-obesity (odds ratio [OR]: 2.75; 95% confidence interval [95% CI]: 1.36-5.55; p-value < 0.05). Hypoalphalipoproteinemia was the most frequent dyslipidemia: 69.46%. An association between count CD4 < 250 and lower HDL cholesterol levels was found (OR: 3.23; 95CI%: 1.61-6.5; p-value < 0.05). CONCLUSIONS: IFG and dyslipidemia are highly prevalent among HIV-infected ART-naïve Mexican patients, therefore, screening for glucose and lipids abnormalities always should be considered among ARTn patients.

ANTECEDENTES: Las alteraciones metabólicas se han vuelto más relevantes en el cuidado de los pacientes con infección por el virus de la inmunodeficiencia humana (VIH). Existe poca información sobre estas alteraciones en pacientes naïve a tratamiento antirretroviral (nTAR). OBJETIVO: Identificar la prevalencia de glucosa alterada en ayuno y dislipidemia entre individuos mexicanos con VIH nTAR e identificar los factores asociados. MÉTODO: Estudio retrospectivo en pacientes con VIH nTAR valorados en un hospital general de la Ciudad de México de 2009 a 2019. Se recabaron datos antropométricos, clínicos, bioquímicos y relacionados con el estado del VIH. RESULTADOS: Se incluyeron 221 pacientes, el 97% hombres, con mediana de edad 30 años (rango intercuartil [RIC]: 25-38), cuenta de linfocitos CD4 250 células/mm3 (RIC: 120.25-391) y carga viral log10 4.69 copias/ml (RIC: 3.64-5.25) de VIH-1 ARN. La prevalencia de glucosa alterada en ayuno fue del 22.6% y presentó asociación con sobrepeso-obesidad (razón de momios [RM]: 2.75; intervalo de confianza del 95% [IC95%]: 1.36-5.55; p < 0.05). La dislipidemia más frecuente fue la hipoalfalipoproteinemia (69.46%), asociada con CD4 < 250 (RM: 3.23; IC95%: 1.61-6.5; p < 0.05). CONCLUSIONES: Las alteraciones en el metabolismo de los lípidos y de la glucosa son frecuentes entre individuos mexicanos con VIH nTAR; por lo tanto, es importante una adecuada evaluación antes de iniciar el tratamiento.

Adherence to antiretroviral therapy and factors associated with non-adherence: a cohort study at two referral services in Brazil.

This cohort study evaluated non-adherence to antiretrovirals at referral services in Pernambuco, Brazil, 2016/2017, through self-report. A generalized mixed-effects model for binary outcomewas used. We assessed 542 participants with an adherence rate of 85.50%. A greater chance of non-adherence was associated with:a low/moderate level of nicotine dependence (OR = 2.79, p = 0.00, IC = 1.44-5.41); ≥7 tablets/day (OR = 6.14, p = 0.00, IC = 3.42-11.02); LPV/r (OR = 1.49, p = 0.6, IC = 0.98-2.26), ddI (OR = 3.34, p = 0.03, IC = 1.12-9.97), ABC (OR = 4.02, p = 0.05, IC = 1.01-16.03), RAL (OR = 2.49, p = 0.01, IC = 1.32-4.70) and DTG (OR = 4.65, p = 0.01, IC = 1.42-15.16); 6-10 year seropositive diagnosis (OR = 2.17, p = 0.01, IC = 1.20-3.92) and symptoms of depression (OR = 1.55, p = 0.03, IC = 1.03-2.33). Protective factors for non-adherence weres: ≥50 years (OR = 0.67, p = 0.06, IC = 0.45-1.01), secondary/higher education (OR = 0.48, p = 0.00, IC = 0.34-0.70), embarrassment at health service (OR = 0.49, p = 0.04, IC = 0.24-0.97), good understanding of antiretrovirals (OR = 0.62, p = 0.03, IC = 0.40-0.96), adverse event (OR = 0.74, p = 0,06, IC = 0.54-1.01), use of TDF (OR = 0.62, p = 0.01, IC = 0.43-0.90), NVP (OR = 0.41, p = 0.05, IC = 0.71-1.00) and EFZ (OR = 0.48, p = 0.01, IC = 0.29-0.80) and good knowledge of HIV/AIDS/ART. (OR = 0.67, p = 0.07, IC = 0.43-1.04). Variables with stronger association were those linked to ART. Systematic use of self-report adherence is recommended for priority groups.
