RESUMO
INTRODUCTION: Human Immunodeficiency Virus (HIV) infection is still a major global problem, whose drug treatment consists of prophylactic prevention and antiretroviral combination therapy for better pharmacological efficacy and control of the circulating virus. However, there are still pharmacological problems that need to be overcome, such as low aqueous solubility of drugs, toxicity, and low patient adherence. Drug delivery technologies can be used to overcome these barriers. OBJECTIVE: This review summarized the latest drug delivery systems for HIV treatment. Initially, an overview of the current therapy was presented, along with the problems it presents. Then, the latest drug delivery systems used to overcome the challenges imposed in conventional HIV therapy were discussed. CONCLUSION: This review examines innovative approaches for HIV treatment, where various drug delivery systems have shown significant advantages, such as high drug encapsulation, improved solubility, and enhanced bioavailability both in vitro and in vivo. Strategies like cyclodextrins, solid dispersions, microneedles, and nanoparticles are explored to address challenges in drug solubility, bioavailability, and administration routes. Despite progress, obstacles like limited clinical trials and industrial scalability hinder the widespread adoption of these formulations, emphasizing the need for further research and collaboration to optimize and ensure accessibility of innovative HIV therapies, mainly in regions where access to HIV treatment is scarce and remains a challenge.
RESUMO
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)

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.
RESUMO
Introducción: La lipodistrofia asociada al virus de la inmunodeficiencia humana es un importante factor de riesgo cardiovascular, que se presenta entre el 10 y el 80 % de los casos, atenta contra la calidad de vida y disminuye la adherencia terapéutica. Resulta de gran interés su prevención y tratamiento. Objetivo: Describir los factores de riesgo que contribuyen a su desarrollo, sus aspectos fisiopatológicos y el tratamiento. Métodos: Se realizó una búsqueda bibliográfica en inglés y español. Se consultaron las bases de datos Pubmed, SciELO, Lilacs, Cochrane Library y Web of Science. La estrategia de búsqueda que se empleó fue: VIH OR sida AND lipodistrofia AND tejido adiposo AND terapia antirretroviral. Información, análisis y síntesis: La lipodistrofia se caracteriza por lipoatrofia de las extremidades, cara y glúteos, lipohipertrofia del área visceral, cervical y dorsocervical, o una combinación de estos. Las proteínas del virus de inmunodeficiencia humana realizan modificaciones en la regulación de genes que provocan inhibición de la diferenciación de los adipocitos y aumento de la apoptosis, a lo que contribuye el estado basal inflamatorio sistémico producido por el mismo virus. Los antirretrovirales desempeñan un papel importante en la génesis de dicha lipodistrofia. Conclusiones: El sexo femenino, la malnutrición y la edad avanzada son algunos de los factores de riesgo más relevantes asociados a la lipodistrofia del virus de inmunodeficiencia humana en la cual influyen los efectos propios del virus y la terapia antirretroviral. No existe un tratamiento farmacológico eficaz, solo se contemplan medidas higiénico-dietéticas y la cirugía estética(AU)´
Introduction: Human immunodeficiency virus associated-lipodystrophy is an important cardiovascular risk factor that develops in 10% to 80% of the cases, impairs quality of life, and reduces adherence to treatment. Its prevention and treatment is of great interest. Objective: To describe the risk factors that contribute to the development, pathophysiological aspects and treatment of human immunodeficiency virus associated-lipodystrophy. Methods: A bibliographic search in English and Spanish was conducted. Pubmed, SciELO, Lilacs, Cochrane Library and Web of Science databases were consulted. The search strategy used was: HIV OR AIDS AND lipodystrophy AND adipose tissue AND antiretroviral treatment. Information, Analysis and Synthesis: Lipodystrophy is characterized by lipoatrophy of the upper and lower limbs, face and buttocks; lipohypertrophy of the visceral, cervical and dorsocervical areas, or a combination of them. Human immunodeficiency virus proteins make modifications in the gene regulation that inhibits the adipocyte differentiation and increases apoptosis, favored by the systemic inflammatory basal state caused by the virus itself. Antiretrovirals play an important role in the genesis of lipodystrophy. Conclusions: Female sex, malnutrition, and older ages are some of the main risk factors of the human immunodeficiency virus associated-lipodystrophy, which is influenced by the effects of the virus itself and the antiretroviral therapy. An effective drug treatment is not available, only hygienic-dietary measures and aesthetic surgery are considered(AU)

Introducción: Se estima que en 2019 vivían 38 millones de personas con el virus de la inmunodeficiencia humana (VIH), para quienes es fundamental el tratamiento antirretroviral (TAR); sin embargo, no siempre funciona. El fracaso terapéutico del TAR sucede cuando existe una progresión de la enfermedad en parámetros clínicos, virológicos o inmunológicos con un peor pronóstico. Objetivo: Identificar los factores asociados al fracaso terapéutico del TAR en personas viviendo con VIH. Métodos: Se siguieron los lineamientos para revisiones sistemáticas de PRISMA-SCR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews), modificados por Tricco y otros. Los artículos sobre el fracaso terapéutico en población adulta en primera línea de TAR se hallaron en PubMed y la Biblioteca Virtual de Salud. Información, análisis y síntesis: La definición de fracaso terapéutico utilizada en ocho artículos corresponde con los criterios de la OMS; el resto emplea el criterio virológico con distintos puntos de corte. Se describen factores asociados con el fracaso terapéutico con significación estadística, agrupados en factores sociodemográficos (sexo, edad, edad inicio del TAR, compartir estatus de VIH, empleo de drogas inyectables y nivel educativo) y factores clínicos (niveles de linfocitos T CD4+ al inicio del TAR, nivel de adherencia, cambio de régimen, estadio de la OMS al inicio del TAR y coinfección por tuberculosis). Conclusiones: Dos factores fundamentales en el fracaso terapéutico son los sociodemográficos y los clínicos que dependen de la accesibilidad al tratamiento, el sistema de salud y las características intrínsecas de los individuos, incluyendo las conductas en relación con su enfermedad(AU)
Introduction: It is estimated that by 2019 there are 38 million people living with the human immunodeficiency virus (HIV), for whom antiretroviral treatment is essential. Treatment failure occurs when there is a progression of the disease in clinical, virological, or immunological parameters that lead to a change in treatment and a worse prognosis of the disease. The objective of this panoramic review is to answer the following question: What are the factors associated with the therapeutic failure of antiretroviral treatment in people living with HIV? Methods: A panoramic review was carried out following the guidelines for systematic reviews suggested by PRISMA-SCR (Preferred Reporting Items for Systematic Reviews and Meta-Analyzes extension for Scoping Reviews) and modified by Tricco et al. The articles on therapeutic failure in the adult population on the first line of ART were rescued from PubMed and the Virtual Health Library (VHL). The search was limited to a period from 2010 to 2020 and articles whose population was children or pregnant women and articles not available in English or Spanish were excluded. Information, Analysis and Synthesis: The definition of therapeutic failure used corresponds to the WHO criteria in eight articles, while the rest use the virological criterion in variable reference points. Regarding the factors associated with treatment failure, those with statistical significance grouped into sociodemographic factors (sex, age, age of ART onset, shared HIV status, injection drug use, and educational level) and clinical factors (T CD4+ levels are described at the start of ART, level of adherence, change of regimen, WHO stage at the start of ART, and tuberculosis coinfection). Conclusions: Two fundamental factors in therapeutic failure are sociodemographic and clinical, which in turn depend on accessibility to treatment, the health system and intrinsic characteristics of the individuals and the behaviors they adopt in relation to their disease(AU)

The purpose of this study was to identify factors associated with HIV-associated neurocognitive disorder (HAND) and symptoms of anxiety and depression in HIV+ Brazilian elderly on antiretroviral treatments. The study included 112 HIV+ elderly who completed a questionnaire, tests for cognitive screening, attention, problem solving, processing speed, visual perception, memory, and anxiety and depression scales. The results showed presence of HAND (89.3%), pathological anxiety (48.2%) and depression (58%) in the sample. Higher income was a protective factor for HAND (OR = 0.33). Waking up well-rested (OR = 0.63) and better diet quality (OR = 0.62) reduced the chance of pathological anxiety. Higher education (OR = 0.74) and waking up well-rested (OR = 0.61) reduced the chance of depression. Being female (OR = 7.73) increased the chance of depression. It can be concluded that it is important to evaluate cognitive and emotional aspects of HIV+ elders and to consider social and educational status, diet, and sleep in interventions, paying special attention to elderly women.
RESUMO
Nowadays, the HIV pandemic is far from controlled. HIV+/AIDS patients show a serious risk of developing resistance to HIV antiretroviral drugs and to be orally colonized by albicans and non-albicans Candida strains resistant to antifungals. As a consequence, new drugs that possess anti-candidal and anti-HIV effects would represent an alternative in the comprehensive treatment of HIV+/AIDS patients. The present study evaluates the possible anti-HIV and anti-Candida effects of a methanolic extract from Heteropterys brachiata (Hb MeOH), an American tropical plant. The anti-HIV effect of Hb MeOH was tested using a non-radioactive colorimetric method (Lenti RT® Activity Assay; Cavidi Tech) that uses reverse transcriptase of HIV-1 enzyme as enzymatic target. The anti-candidal effect of HbMeOH extract was evaluated by following a standardized test protocol of microdilution for yeast using the Candida albicans strain ATCC® 90028. The Hb MeOH at 1 mg/mL concentration shows 38.5% RT-HIV inhibition, while Hb MeOH at 10 mg/mL concentration produced 98% C. albicans growth inhibition. Our findings show that the Hb MeOH possesses a strong anti-candidal activity and moderate anti-HIV effect and suggests that the plant extract could be considered as a potential candidate for HIV/AIDS treatment.

The success of antiretroviral treatment (ART) is threatened by the emergence of drug resistance mutations (DRM). Since Brazil presents the largest number of people living with HIV (PLWH) in South America we aimed at understanding the dynamics of DRM in this country. We analyzed a total of 20,226 HIV-1 sequences collected from PLWH undergoing ART between 2008-2017. Results show a mild decline of DRM over the years but an increase of the K65R reverse transcriptase mutation from 2.23% to 12.11%. This increase gradually occurred following alterations in the ART regimens replacing zidovudine (AZT) with tenofovir (TDF). PLWH harboring the K65R had significantly higher viral loads than those without this mutation (p < 0.001). Among the two most prevalent HIV-1 subtypes (B and C) there was a significant (p < 0.001) association of K65R with subtype C (11.26%) when compared with subtype B (9.27%). Nonetheless, evidence for K65R transmission in Brazil was found both for C and B subtypes. Additionally, artificial neural network-based immunoinformatic predictions suggest that K65R could enhance viral recognition by HLA-B27 that has relatively low prevalence in the Brazilian population. Overall, the results suggest that tenofovir-based regimens need to be carefully monitored particularly in settings with subtype C and specific HLA profiles.

We present a case of a 48-year-old white HIV-1 positive man who presented an acute myocardial infarction. The patient was on ART for the last ten years with emtricitabine/tenofovir and ritonavir-boosted fosamprenavir. Eplerenone 25 mg/day was also initiated due to a left ventricular dysfunction. A week after discharge a routine laboratory examination revealed severe hyperkalaemia. Due to suspicion of a potential drug-drug interaction, both eplerenone and ARVs were interrupted. Despite daily treatment for hyperkalaemia, serum potassium levels normalized after two weeks. Eplerenone is metabolized by the hepatic P450 cytochrome isoenzyme CYP3A4; therefore, concomitant administration with CYP3A4 inhibitors, like ritonavir, may increase plasma levels of eplerenone and, therefore, the risk of side effects, mainly hyperkalaemia. Based on this case, it is important to alert the medical community of this possible life-threatening drug-drug interaction between eplerenone and ritonavir-boosted protease inhibitor.

O estudo examinou fatores sociodemográficos, clínicos e psicossociais que afetam a continuidade do tratamento e a adesão à medicação antirretroviral em mulheres nos primeiros três meses após o parto. Participaram 56 mulheres vivendo com HIV, com idades entre 18 e 43 anos, na sua grande maioria brancas e casadas. Foram utilizadas entrevistas sobre dados sociodemográficos e clínicos, exames laboratoriais e escalas psicológicas. Análises estatísticas revelaram que mais de um terço das participantes (37,5%) descontinuaram o próprio tratamento após o parto. A qualidade de vida e o apoio instrumental podem favorecer a continuidade do tratamento de HIV após o parto, e as condições de trabalho e a situação clínica dessas mulheres pode afetar a adesão após o parto. Tais resultados podem contribuir para o desenvolvimento de intervenções que favoreçam a continuidade do tratamento e adesão das mulheres no pós-parto. (AU)
This study examined sociodemographic, clinical, and psychosocial factors affecting retention in HIV care and antiretroviral adherence in women during the first three months after delivery. Participants were 56 women living with HIV, aged between 18 and 43 years, mostly white and married. We used interviews about socio-demographic and clinical data, laboratory tests, and psychological scales. Statistical analyses revealed that more than one-third of women (37.5%) discontinued their treatment after delivery. Quality of life and instrumental support may contribute to retention in HIV care after childbirth, and the working conditions and clinical status of these women may affect adherence after childbirth. These findings may contribute to the development of interventions that promote retention in HIV care and adherence during the postpartum period. (AU)
Este estudio examinó los aspectos sociodemográficos, clínicos y psicosociales que afectan la continuidad del tratamiento del VIH y adherencia a los antirretrovirales en las mujeres en los tres meses después del parto. Participaron 56 madres infectadas por VIH, con edades comprendidas entre 18 y 43 años. La mayoría eran blancas y estaban casadas. Se utilizaron entrevistas sobre datos sociodemográficos y clínicos, exámenes de laboratorio y escalas psicológicas. Los análisis estadísticos revelaron que más de un tercio de las mujeres (37,5%) interrumpieron su tratamiento después del parto. La calidad de vida y el apoyo instrumental pueden favorecer la continuidad del tratamiento del VIH después del parto, y que las condiciones laborales y la situación clínica de estas mujeres pueden afectar la adherencia después del parto. Estos resultados pueden contribuir al desarrollo de intervenciones para favorecer la continuidad del tratamiento y la adherencia de las mujeres en el posparto. (AU)

OBJECTIVE: To evaluate the uptake of perinatal HIV preventive interventions by the risk of perinatal HIV transmission in mother-infant pairs in a high-HIV prevalence area in the US. STUDY DESIGN: This was a retrospective cohort study of mother-infant pairs with perinatal HIV exposure during 2013-2017 managed at a subspecialty pediatric HIV program in Washington, DC. We collected demographic data, maternal HIV history, delivery mode, maternal and infant antiretroviral drug (ARV) use, and infant HIV test results. We compared the uptake of recommended preventive interventions in low-risk (ie, mothers on antiretroviral therapy [ART] with viral suppression) and high-risk (mothers without ART or viral suppression) mother-infant pairs using the Pearson chi-square, Fisher exact, and Wilcoxon rank-sum tests and logistic regression. RESULTS: We analyzed 551 HIV-exposed infants (HEIs) and 542 mothers living with HIV. The majority of mothers received ARVs (95.5%), had HIV RNA ≤1000 copies/mL before delivery (81.9%), and received intrapartum zidovudine (ZDV; 65.5%). The majority of all HEIs were low risk (82.6%) and received postpartum ARVs (98.9%). Among the low-risk infants, 53.2% were delivered via cesarean delivery (CD), and 62.9% and 96.5% were administered intrapartum and postpartum ZDV, respectively. Among high-risk infants, 84.4% were delivered via CD, 78.1% received intrapartum ZDV, and 62.5% received combination ART. Nine high-risk infants acquired HIV perinatally. CONCLUSION: In an area of high HIV prevalence in the US, a large proportion of low-risk HEIs received intrapartum ZDV and were delivered via CD. We also observed missed opportunities for the prevention of perinatal HIV transmission.

La infección por VIH sigue impactando de manera significativa a embarazadas, niños y adolescentes. En las embarazadas, es necesario hacer la prueba de VIH en la primera consulta prenatal o al primer contacto con el sistema de salud, y luego repetir en el tercer trimestre, preferiblemente antes de las 36 semanas de gestación, en caso de que el resultado sea negativo inicialmente; mientras que el diagnóstico en pediatría se basa en la realización de pruebas virológicas (PCR DNA o RNA) en niños menores de 18 meses y de pruebas serológicas en mayores de 18 meses, con seguimientos periódicos a fin de evaluar la evolución clínica, adherencia y posible toxicidad medicamentosa. En ambas poblaciones, es necesario considerar, previo al inicio del TARV la realización del test de resistencia a fin de orientar la terapéutica, con posteriores controles de carga viral plasmática (CVP) y contaje de linfocitos T CD4. La utilización del TARV implica resaltar un objetivo epidemiológico, pues su uso se asocia con riesgo menor de transmisión maternoinfantil. En este consenso se busca disponer de recomendaciones en relación con el diagnóstico y TARV de embarazadas, niños y adolescentes con infección por VIH, las cuales puedan servir de orientación al clínico especialista en el área, dada la complejidad y avances constantes en la investigación de las distintas familias de antirretrovirales, así como su eficacia, toxicidad, interacciones medicamentosas, aparición de resistencias, tropismo y al adecuado manejo en diversas situaciones especiales.
HIV infection continues to significantly impact pregnant women, children and adolescents. In pregnant women, it is necessary to do the HIV test at the first prenatal visit or at the first contact with the health system, and then repeat in the third trimester, preferably before 36 weeks of gestation, in case the result is negative. initially; while the diagnosis in pediatrics is based on the performance of virological tests (DNA or RNA PCR) in children younger than 18 months and serological tests in those older than 18 months, with periodic follow-ups in order to evaluate the clinical evolution, adherence and possible drug toxicity. In both populations, it is necessary to consider, prior to the start of ART, the performance of the resistance test in order to guide therapy, with subsequent controls of plasma viral load (CVP) and CD4 T lymphocyte count. The use of ART implies highlighting an epidemiological objective, since its use is associated with a lower risk of mother-to-child transmission. This consensus seeks to have recommendations in relation to the diagnosis and ART of pregnant women, children and adolescents with HIV infection, which can serve as guidance to the clinical specialist in the area, given the complexity and constant advances in the investigation of the different families of antiretrovirals, as well as their efficacy, toxicity, drug interactions, emergence of resistance, tropism and proper management in various special situations.
RESUMO
La infección por el VIH, es un problema de salud pública mundial. Los conocimientos en relación con el virus, su historia natural, diagnóstico y enfermedades asociadas está en constante evolución, tanto como el tratamiento antirretroviral (TARV). En Venezuela, según datos reportados por ONUsida, para el año 2019, existían 110 000 personas que vivían con VIH entre adultos y niños, con una prevalencia del 0,6 % y una tasa de 0,33 por 1 000 habitantes, en las personas con edades comprendidas entre 15 y 49 años. Desafortunadamente estos datos demuestran que Venezuela no pudo alcanzar las metas de 90-90-90 promovidas por ONUSida para el año 2020, poniendo en evidencia, unas 5 200 nuevas infecciones en 2019, de las cuales 4 700 correspondían a mayores de 15 años, por lo que afianzar el conocimiento de la epidemia, de sus mecanismos de transmisión y prevención es vital. La utilización del TARV implica resaltar su objetivo epidemiológico, pues su uso se asocia con menor riesgo de transmisión y reducción de nuevas infecciones, por lo que se recomienda su inicio lo más temprano posible, independientemente del contaje de linfocitos T CD4 y CVP en todos los pacientes con infección por VIH. Resulta necesario disponer de recomendaciones actualizadas en relación con el TARV, que sirvan de orientación al clínico especialista en el área, dada la complejidad y constantes avances en la investigación de las distintas familias de antirretrovirales, así como su eficacia, toxicidad, interacciones medicamentosas, aparición de resistencias, tropismo y al adecuado manejo en diversas situaciones especiales. Este consenso busca brindar una orientación general en algunos aspectos de importancia del VIH y el sida así como de su diagnóstico y tratamiento.
HIV infection is a global public health problem. Knowledge in relation to the virus, its natural history, diagnosis and associated diseases is constantly evolving, as is antiretroviral therapy (ART). In Venezuela, according to data reported by UNAIDS, for the year 2019, there were 110 000 people living with HIV among adults and children, with a prevalence of 0.6 % and a rate of 0.33 per 1 000 inhabitants, in people with ages between 15 and 49 years. Unfortunately, these data show that Venezuela could not reach the goals of 90-90-90 promoted by UNAIDS for the year 2020, highlighting some 5 200 new infections in 2019, of which 4 700 corresponded to those over 15 years of age, so consolidating knowledge of the epidemic, its transmission and prevention mechanisms is vital. The use of ART implies highlighting its epidemiological objective, since its use is associated with a lower risk of transmission and reduction of new infections, so it is recommended to start it as early as possible, regardless of the CD4 and CVP T lymphocyte count in all HIVinfected patients. It is necessary to have up-to-date recommendations in relation to ART, which serve as guidance to the specialist clinician in the area, given the complexity and constant advances in research of the different families of antiretrovirals, as well as their efficacy, toxicity, drug interactions, appearance of resistance, tropism and proper handling in various special situations. This consensus seeks to provide general guidance on some important aspects of HIV and AIDS, as well as their diagnosis and treatment.
RESUMO
Resumen Objetivo: El presente estudio tuvo como objetivo evaluar los niveles de adherencia al tratamiento antirretroviral, así como determinar los factores psicológicos predictores de la no adherencia a dicho tratamiento en pacientes con VIH-SIDA. Método: Diseño descriptivo, transversal y correlacional. La muestra estuvo conformada por 25 personas diagnosticadas con VIH-SIDA que asistieron a los servicios integrales de una asociación civil en la ciudad de Guadalajara, México, y que se encontraban bajo tratamiento antirretroviral. Se utilizó el Cuestionario de adherencia al tratamiento para el VIH-SIDA [CAT-VIH] y el Cuestionario de Factores Relacionados con la Adherencia al Tratamiento para el VIH/SIDA (CFR-AT VIH). Se realizaron análisis descriptivos y no paramétricos para la comparación de las variables de estudio, así como sus respectivas correlaciones. Resultados: Solo 60% de los evaluados presentan una adecuada adherencia al tratamiento con antirretrovirales; además se encontraron diferencias significativas entre adherentes y no adherentes en las variables de autoeficacia (Z=-3.196; p=.001); estrés (Z=-2.033; p=.042); y depresión (Z=-2.409; p=.016). Se obtuvieron correlaciones positivas de la adherencia con autoeficacia (r=.750; p=.000) y apoyo social (r=.462; p=.020) y correlaciones negativas con estrés (r=-.543; p=.005) y depresión (r=-.544; p=.005). Conclusiones: A mayores estados de estrés y depresión, menor serán los niveles de adherencia al tratamiento con antirretrovirales; por lo cual estas variables deben ser tomadas en cuenta para el diseño de estrategias de mejora de la adherencia en personas con VIH-SIDA.
Abstract Objective: Objective: The main aim of this study was to evaluate the levels of adherence to antiretrovirals treatment as well as to determine the psychological factors that predict the non-adherence to antiretrovirals in HIV patients who attend a civil association in Guadalajara, México. Method: It was a descriptive, transversal and correlational design. The sample consisted of 25 patients diagnosed with HIV who attended integral services of a Civil Association. The Adherence to Treatment for HIV/AIDS Questionnaire [CAT-HIV] and the Questionnaire of Factors Related to Adherence to Treatment for HIV/AIDS (CFR-AT HIV) were used. Descriptive and nonparametric analyzes were carried out to compare the study variables, as well as their respective correlations, all through the statistical program SPSS v.20. Results: Only 60% of those evaluated showed adequate adherence to antiretrovirals; in addition, significance differences between adherents and non-adherents in the self-efficacy variable (Z = -3.196, p = .001); stress (Z = -2.033, p = .042); and depression (Z = -2.409, p = .016). Positive correlations of adherence were obtained with self-efficacy (r = .750, p = .000) and social support (r = .462, p = .020) and negative correlations with stress (r = - .543; p = .005) and depression (r = -. 544; p = .005). Conclusions: The higher levels of stress and depression, the lower the levels of adherence to antiretroviral treatment; therefore, these variables must be considered in the design of strategies to improve adherence in people with HIV.
RESUMO
INTRODUCTION: The relative efficacy of different antiretroviral (ART) regimens has been extensively evaluated in the context of clinical trials, using HIV viral load (VL) measurements at pre-specified timepoints after ART onset. However, data from real-life studies using combined longitudinal measurements of cumulative viraemia are scarce. This study aimed to address the independent effect of different ART regimens on HIV cumulative viraemia over the first 12 months after treatment initiation, using programmatic data from the Ministry of Health of Brazil. METHODS: Retrospective cohort study analysing cumulative viraemia under the most frequently used ART regimens in Brazil (tenofovir, lamivudine and dolutegravir (regimen 1); tenofovir, lamivudine and efavirenz (regimen 2); tenofovir, lamivudine and ritonavir-boosted atazanavir (regimen 3)). RESULTS AND DISCUSSION: We included 112,243 patients >12 years old who received their first ART prescription between January 2014 and August 2017. Univariate analysis indicated that cumulative viraemia was significantly lower in patients receiving regimen 1 as compared with those receiving regimens 2 or 3 (p<0.0001 for both pairwise comparisons). In a multivariable analysis adjusted for age, sex, baseline T CD4+ counts and baseline HIV VL, ART regimen persisted with statistically significant effect on 12-month cumulative viraemia. The model predicted a 45-unit increase in log10 copy-days/mL cumulative viraemia for regimen 2 as compared with regimen 1, and a 70-unit increase in log10 copy-days/mL cumulative viraemia for regimen 3 as compared with regimen 1 (95%CI 41 to 49 and 61 to 79 respectively; p<0.001 for both comparisons). In models restricted to youths (13 to 24 years old) and female patients, ART regimen had similar effects. ART regimen with dolutegravir in association with a tenofovir-lamivudine backbone was superior to regimens containing efavirenz or boosted atazanavir in reducing HIV VL, as shown by cumulative viraemia over the first 12 months after treatment initiation. The superiority persisted even after adjusting the analysis for potential confounders. CONCLUSIONS: Our findings could bring direct benefits to patients as suggested by lower viral replication during treatment, lower risk of HIV transmission, and a potential reduction in resistance mutations in the initial 12 months under ART.

Brazil is a low-and-middle income country (LMIC) that, despite having a large population and continental dimensions, has been able to successfully fight HIV/AIDS through a number of governmental and societal measures. These included an early response to the epidemic, the development of a universal and free public health system, incisive discussions with pharmaceutical companies to reduce antiretroviral (ARV) drug prices, investments towards the development of generic drugs and compulsory licensing of ARVs. Through such measures, Brazil is among the leading LMIC towards achieving the 90-90-90 UNAIDS goals in the years to come. In this review, we analyze Brazil's progress throughout the HIV/AIDS epidemic to achieve state-of-the-art ARV treatment and to reduce AIDS mortality in the country. The top-quality HIV/AIDS research in Brazil towards HIV prophylactic and functional cure, the next step towards the economic sustainability of the battle against HIV, is also discussed.

Despite successful HIV suppression by antiretroviral treatment (ART), immune activation may persist in HIV patients, contributing to an impaired immunological reconstitution and disease progression. Information regarding Hepatitis C virus (HCV) coinfection as a factor that accounts for immune activation in HIV subjects remains unclear. Furthermore, most studies have been carried out considering HIV/HCV patients as a whole, without taking into account the presence or absence of liver damage. Therefore, it is unknown if HCV and/or its liver-related disease could act as two independent factors contributing to the immune activation. In this study, we investigated the presence of immune activation in a cohort of 50 HIV/HCV patients by measuring cytokine levels, CD4+ T-cell counts and CD4/CD8 ratios. Six patient groups were defined according to HIV viral load, HCV status, and liver disease to assess the impact of each of these factors on immune activation and reconstitution in HIV/HCV patients. Only subjects with controlled HIV infection and cleared HCV displayed immunological parameters within normal ranges. The mere presence of HCV contributes to immune activation leading to an inappropriate immunological reconstitution. This state exacerbates in the presence of HCV-associated liver disease. Our results suggest that ART is not enough to suppress immune activation in the context of HIV/HCV coinfection, since both HCV and its liver-related disease would contribute to the immune activation. Given that immune activation worsens immunological reconstitution and clinical status, these results support the priority of HCV treatment in HIV/HCV patients and suggest the monitoring of their liver status.

BACKGROUND: We compared AIDS-related mortality rates in people living with HIV (PLHIV) starting antiretroviral therapy (ART) in Brazil during 2006-2015 and examined associated risk factors . METHODS: Data on ART use in PLHIV and AIDS mortality in Brazil was analysed with piecewise constant exponential models. Mortality rates and hazard ratios were estimated for 0-6, 6-12, 13-24, 25-36 and > 36 months of ART use and adjusted for region, age, sex, baseline CD4 cell count and calendar year of ART initiation. An additional analysis restricted to those with data on risk group was also performed. RESULTS: 269,076 individuals were included in the analysis, 165,643 (62%) males and 103,433 (38%) females, with 1,783,305 person-years of follow-up time. 21,749 AIDS deaths were reported and 8898 deaths occurred in the first year of ART. The risk of death in the first six months decreased with early ART initiation; those starting treatment early with CD4 > 500 cells per µL had a hazard ratio of 0.06 (95% CI 0.05-0.07) compared with CD4 < 200 cells per µL. Older age, male sex, intravenous drug use and starting treatment in earlier calendar years were associated with higher mortality rates. People living in the North, Northeast and South of Brazil experienced significantly higher AIDS mortality rates than those in the Southeast (HR 1.44, [95% CI 1.35-1.54], 1.10 [1.05-1.16] and 1.22 [1.17-1.28] respectively). CONCLUSIONS: Early treatment is likely to have contributed to the improved survival in PLHIV on ART, with the greatest benefits observed in women, younger age-groups and those living in the North.

Introducción: La infección por VIH/SIDA constituye uno de los principales problemas de salud en el mundo con elevadas tasas de morbilidad y mortalidad demostradas. En diferentes estudios epidemiológicos ha quedado confirmado que 36,3 millones de personas vivían con el VIH hasta el año 2015 en todo el mundo. Hasta este momento 78 millones han sido infectados desde 1981, año en que comenzó la epidemia, y el 25 por ciento de los pacientes desconocen que están infectados, lo cual propicia el contagio. Objetivo: Realizar una revisión bibliográfica relacionada con la infección por el VIH/SIDA, sus complicaciones en las enfermedades reumáticas y metabólicas y su respuesta al tratamiento antirretroviral de alta eficiencia. Método: Se realizó una búsqueda bibliográfica en bases de datos nacionales e internacionales y en diferentes fuentes de información para recuperar los artículos relacionados con el tema sobre el VIH-SIDA, las complicaciones reumáticas y metabólicas y su respuesta al tratamiento antirretroviral de alta eficiencia, tema escogido para este trabajo. Resultados: Se recuperaron 78 artículos y nueve textos que trataban temas relacionados con la infección por VIH-SIDA; de ellos fueron útiles para nuestros objetivos 55 documentos que forman parte de nuestras referencias bibliográficas, los cuales agrupamos de acuerdo con los diferentes temas planteados para este estudio y se llegó a conclusiones útiles para nuestra comunidad científica. Conclusiones: Las enfermedades reumáticas y autoinmunes han sido diagnosticadas con mucha frecuencia en los pacientes infectados con el VIH-SIDA en Cuba y en el mundo antes del tratamiento antirretroviral de alta eficiencia, mediante el cual ha aumentado la expectativa de supervivencia de estos enfermos y disminuido la aparición de síntomas clínicos y afecciones, así como infecciones oportunistas, después de su inclusión en el enfoque terapéutico(AU)
Introduction: HIV/AIDS infection is one of the main health problems worldwide, with high morbidity and mortality. Different epidemiological studies have confirmed that 36.3 million people worldwide were living with HIV until 2015. So far, 78 million have been infected since 1981, the year in which the epidemic began, and 25 percent of patients do not know they are infected, which spreads infection. Objective: To carry out a literature review about HIV/AIDS infection, its complications in rheumatic metabolic manifestations, and its response to highly efficient antiretroviral treatment. Method: A literature search was carried out in the databases PudMed/MEDLINE, Cumed and Lilac, as well as in the regional information sources SciELO and ScienceDirect, using the key phrases manifestaciones reumáticas y VIH-SIDA [rheumatic manifestations and HIV-AIDS], complicaciones metabólicas y VIH-SIDA [metabolic complications and HIV-AIDS], tratamiento antirretroviral de alta eficiencia y VIH-SIDA [high-efficiency antiretroviral treatment and HIV-AIDS], in order to recover the articles about HIV-AIDS and rheumatic and metabolic complications and their response to highly efficient antiretroviral treatment. Results: 78 articles and nine texts dealing about the aforementioned topics were recovered; of them, 55 documents that are part of our bibliographical references were useful for our purposes, which were grouped according to the different topics proposed for this study. We reached useful conclusions for our scientific community. Conclusions: Rheumatic and autoimmune diseases have been diagnosed very frequently in patients infected with HIV/AIDS in Cuba and worldwide during the era prior to highly efficient antiretroviral treatment. Its incorporation into the therapeutic approach has increased the survival expectations of these patients, in addition to the substantial decrease in the appearance of clinical symptoms and conditions, especially the inflammatory arthritic conditions, seronegative spondyloarthropathies, psoriasis and opportunistic infections(AU)
