RESUMO

INTRODUCTION: The impact of specific policies on HIV care has been scarcely investigated. In this study we aimed to analyze the impact of the Treatment For All policy (TFA-2013) and the adoption of integrase strand transfer inhibitors (INSTIs-2017) as first-line therapy on clinical indicators of people living with HIV (PLHIV) in Brazil. METHODS: We assessed the public database of Brazil's Ministry of Health and extracted data from 2009 to 2019. We investigated the impact of TFA and INSTIs with a time-series analysis of four health indicators in PLHIV: antiretroviral treatment (ART) initiation with a CD4+ count >500/mm3 ; ART initiation <1 month after the first CD4+ measurement; viral load suppression (VLS); and treatment adherence. We explored trends over time by gender, age, macroregion of residency and municipal-level social vulnerability index. RESULTS: We included 753 316 PLHIV in 2019. Most were males (64.81%) in the 30-49 years age category (50.86%). We observed an overall improvement in all HIV clinical indicators, with notable impact of TFA on timely ART initiation and VLS, and mild impact of INSTIs on treatment adherence. Such improvements were heterogeneous, with remarkable gaps in gender, age and socioeconomic groups that have persisted over time. Indicators point to inferior outcomes among children, older adults, women and people living in socially vulnerable locations. CONCLUSIONS: Recent Brazilian public policies have had positive impacts on key HIV clinical indicators. However, our results highlight the need for specific policies to improve HIV care for children, older adults, women and socially vulnerable groups.

RESUMO

BACKGROUND: The clinical outcomes of antiretroviral drugs may be modified through drug interactions; thus, it is important to update the drug interactions in people living with HIV (PLHIV). AIM: To update clinically relevant drug interactions in PLHIV on antiretroviral therapy with novel drug interactions published from 2017 to 2022. METHODS: A systematic review in Medline/PubMed database from July 2017 to December 2022 using the Mesh terms antiretroviral agents and drug interactions or herb-drug interactions or food-drug interactions. Publications with drug interactions in humans, in English or Spanish, and with full-text access were retrieved. The clinical relevance of drug interactions was grouped into five levels according to the gravity and probability of occurrence. RESULTS: A total of 366 articles were identified, with 219 (including 87 citation lists) were included, which allowed for the identification of 471 drug interaction pairs; among them, 291 were systematically reported for the first time. In total 42 (14.4%) and 137 (47.1%) were level one and two, respectively, and 233 (80.1%) pairs were explained with the pharmacokinetic mechanism. Among these 291 pairs, protease inhibitors (PIs) and ritonavir/cobicistat-boosted PIs, as well as integrase strand transfer inhibitors (InSTIs), with 70 (24.1%) and 65 (22.3%) drug interaction pairs of levels one and two, respectively, were more frequent. CONCLUSIONS: In PLHIV on antiretroviral therapy, we identify 291 drug interaction pairs systematically reported for the first time, with 179 (61.5%) being assessed as clinically relevant (levels one and two). The pharmacokinetic mechanism was the most frequently identified. PIs, ritonavir/cobicistat-boosted PIs, and InSTIs were the antiretroviral groups with the highest number of clinically relevant drug interaction pairs (levels one and two).

RESUMO

Dentre os fatores associados à adesão à Terapia Antirretroviral (TARV) em pessoas vivendo com HIV, destaca-se a religiosidade/espiritualidade (R/E). O objetivo deste estudo foi apresentar as evidências disponíveis sobre a relação entre a dimensão da R/E e a adesão aos antirretrovirais. Realizou-se uma revisão integrativa de literatura com buscas nas bases/bibliotecas CINAHL, LILACS, PePSIC, PsycINFO, PubMed, SciELO, Scopus e Web of Science. Foram selecionados artigos empíricos publicados entre janeiro de 2008 e junho de 2019, sendo recuperados 49 estudos após a aplicação dos critérios de inclusão/exclusão. Encontraram-se associações positivas, negativas e neutras entre R/E e adesão à TARV, evidenciando que a R/E é uma dimensão psicossocial que pode ser preditora da adesão aos antirretrovirais. O sentido dessa influência, no entanto, ainda não é um consenso na literatura científica. Recomenda-se que essas influências sejam compreendidas a partir de elementos contextuais dessa população e não apenas de marcadores pessoais (AU).

Religiosity and spirituality (R/S) have stood out among factors associated with adherence to antiretroviral therapy (ART) in people living with HIV. This study aimed to identify evidence on the relationship between R/S and adherence to ART. An integrative literature review was conducted within the CINAHL, LILACS, PePSIC, PsycINFO, PubMed, SciELO, Scopus, and Web of Science databases. Empirical articles published between January 2008 and June 2019 were selected, and 49 studies were retrieved after applying the inclusion/exclusion criteria. Positive, negative, and neutral associations were found between R/S and adherence to ART, showing that R/S is a psychosocial dimension that can be a predictor of adherence to antiretrovirals. The meaning of this influence, however, is not yet a consensus in the scientific literature. It is recommended that these influences be understood from the contextual elements of this population and not just from personal markers (AU).

El objetivo de este estudio fue presentar las evidencias disponibles sobre la relación entre la dimensión de la R/E y la adherencia a los antirretrovirales. Se realizó una revisión integradora de la literatura con búsquedas en las bases de datos/bibliotecas CINAHL, LILACS, PePSIC, PsycINFO, PubMed, SciELO, Scopus y Web of Science. Se seleccionaron artículos empíricos publicados entre enero de 2008 y junio de 2019, y se recuperaron 49 estudios tras aplicar los criterios de inclusión/exclusión. Fueron encontradas asociaciones positivas, negativas y neutras entre la R/E y la adherencia al TARV, lo que demuestra que la R/E es una dimensión psicosocial que puede ser un predictor de la adherencia a los medicamentos antirretrovirales. Sin embargo, el significado de esta influencia aún no está consensuado en la literatura científica. Se recomienda que estas influencias se entiendan a partir de los elementos contextuales de esta población y no solo de los marcadores personales (AU).

RESUMO

Resumen La afectación del virus de la inmunodeficiencia humana (VIH) ha cambiado tras el inicio del tratamiento antirretroviral de gran actividad, ya que este ha generado una mayor supervivencia y un menor número de comorbilidades en los pacientes. Es común que en las personas con VIH el fracaso renal agudo esté asociado a sepsis, toxicidad por fármacos o afección directa por el propio virus. La nefropatía en pacientes con VIH es variada y puede estar asociada al uso de medicamentos o directamente al efecto del virus. La prevalencia de esta patología en este tipo de pacientes es <10% y se caracteriza por un colapso glomerular. Las células del parénquima renal expresan los receptores de quimiocinas CCR5 y CXCR4, que son esenciales para la entrada de cepas de VIH-1 en las células. El presente caso es particularmente interesante ya que la insuficiencia renal aguda en el marco de un síndrome nefrótico fue la primera manifestación en un paciente con VIH/sida.

Abstract : Human immunodeficiency virus infection has changed after the start of highly active antiretroviral treatment, generating greater survival and fewer patient comorbidities. In these patients, the finding of acute renal failure is common, which may be associated with sepsis, drug toxicity, or direct involvement by the virus itself. Nephropathy in patients with HIV infection is varied, where it can be associated with the use of medications or directly due to the effect of the virus (HIVAN). The prevalence is less than 10 % and is characterized by glomerular collapse. Renal parenchyma cells express the chemokine receptors CCR5 and CXCR4 that are essential for the entry of HIV-1 strains into cells. The present case is interesting, since acute renal failure in the framework of a nephrotic syndrome was the first manifestation of a patient with HIV / AIDS.

RESUMO

The HIV/AIDS epidemic is an ongoing threat to public health. Its elimination requires greater efforts to broaden antiretroviral treatment coverage, availability and personalization. HIV drug resistance is currently a global problem due to its continuing increase in recent years, undermining efficacy of antiretroviral therapy. Pretreatment HIV drug-resistance surveillance is part of WHO's strategy for addressing antiretroviral drug resistance. This paper describes and analyzes pretreatment HIV drug-resistance surveillance in Cuba. It presents a chronology of HIV resistance studies in untreated patients, along with their results and programmatic actions related to first- and second-line treatment regimens. Cuba's incorporation into the Global HIV Drug Resistance Surveillance Laboratories Network and the advantages of having a WHO-designated laboratory in which to conduct periodic studies of HIV drug-resistance surveillance are described. HIV drug-resistance surveillance in Cuba is a necessary tool in HIV/AIDS monitoring and control, as it obtains population-scale data used to inform programmatic decisions related to optimizing first- and second-line treatments for children and adults, as well as helping meet goals of eliminating HIV transmission.

RESUMO

INTRODUCTION: Disease and deaths from HIV/AIDS have decreased since antiretroviral treatment was introduced in 1996. Since 2005, as treatment availability has increased worldwide, deaths from HIV/AIDS have declined 48%. As of November 2019, 26,952 cases have been reported in Cuba, of which 5159 (19.1%) are deceased. The country has experienced a reduction in mortality rates since 2002, when antiretroviral treatment became available. Although there are clearly benefits to treatment, it is important to understand antiretroviral safety profiles as their toxicity may lower treatment adherence. OBJECTIVE: Describe adverse reactions attributable to antiretrovirals used in Cuban patients living with HIV/AIDS. METHODS: I studied notifications of adverse reactions to antiretrovirals used in Cuban patients with HIV/AIDS from January 2003 to December 2017. The sample consisted of 352 notifications in the National Pharmacovigilance Database regarding adverse reactions attributed to antiretrovirals. The variables considered were sex, notification year, antiretroviral drug, and number, type, frequency and severity of adverse reactions, whether or not they were preventable, and the reasons for categorizing them as they were. RESULTS: Antiretrovirals reported an average adverse reaction rate of 2.1 per million population per year, representing 24.2% of adverse reactions produced by the antiviral drug group in that period. Adult males represented 75% (264/352) of patients who had adverse reactions to antiretrovirals. Most adverse reactions were in response to nevirapine (29.0%; 102/352) and zidovudine (26.7%; 94/352). The most frequent reactions were hypersensitivity (24.4%; 86/352), digestive disorders (15.9%; 56/352) and anemia (15.6%; 55/352). Reactions were common (62.5%; 220/352) and moderate in severity (70.4%; 248/352). Preventable reactions made up 52.6% (185/352) of adverse reactions. Of preventable reactions, 68.1% (126/185) were associated with drug interactions and 16.2% (30/185) with improper dosage or prescription errors. CONCLUSIONS: Adverse reactions to antiretrovirals in Cuban patients are common and moderate in severity. The drug with the most notifications was nevirapine, and the most common adverse reaction was hypersensitivity. More than half of adverse reactions are considered preventable, and their main causes are prescription errors.

RESUMO

INTRODUCTION: Combined antiretroviral therapy has led to significant decreases in morbidity and mortality in acquired immunodeficiency syndrome patients. Survival among these patients admitted to intensive care units has also improved in the last years. However, the prognostic predictors of human immunodeficiency vírus patients in intensive care units have not been adequately studied. The main objective of this study was to evaluate if non-adherence to antiretroviral therapy is a predictor of hospital mortality. METHODS: A unicentric, retrospective, cohort study composed of patients admitted to a 59-bed mixed intensive care unit including all patients with human immunodeficiency vírus infection. Patients were excluded if exclusive palliative care was established before completing 48 h of intensive care unit admission. Clinical and treatment data were obtained, including demographic records, underlying diseases, Simplified Acute Physiology III score at the time of intensive care unit admission, CD4 lymphocyte count, antiretroviral therapy adherence, admission diagnosis, human immunodeficiency vírus-related diseases, sepsis and use of mechanical ventilation and hemodialysis. The outcome analyzed was hospital mortality. RESULTS: Overall, 167 patients were included in the study, and intensive care unit mortality was 34.7%. Multivariate analysis indicated that antiretroviral therapy adherence and the Simplified Acute Physiology 3 score were independently related to hospital mortality. antiretroviral therapy adherence was a protective factor (OR 0.2; 95% CI 0.05-0.71; P = 0.01), and Simplified Acute Physiology 3 (OR 1.04; 95% CI 1.01-1.08; P < 0.01) was associated with increased hospital mortality. CONCLUSION: Non-adherence to antiretroviral therapy is associated with hospital mortality in this population. Highly active antiretroviral therapy non-adherence may be associated with other comorbidities that may be associated with a worst prognosis in this scenario.

RESUMO

INTRODUCTION: Antiretroviral treatment for HIV generates dyslipidemia, which is associated with cardiovascular risk and atherosclerosis. OBJECTIVE: To compare antiretroviral agents effects on lipids in patients with HIV-AIDS. METHODS: Retrospective cohort. The lipid profiles of patients receiving efavirenz (EFV) vs. atazanavir (ATV) with a zidovudine + lamivudine backbone for 36 months were compared. RESULTS: 212 patients were included in the study. From baseline to month 36, HDL increase in the group of patients treated with ATV was higher in comparison with that of patients on EFV (8.33 vs. 4.26; p < 0.01); a difference in triglycerides was observed between groups, with a decrease of 19.06 mg/dL in patients on ATV and an increase of 40.62 mg/dL in those who received EFV (p < 0.001). Mean difference in total and LDL-cholesterol change between both treatments was not significant (p = 0.32 and p = 0.951, respectively). CONCLUSIONS: ATV-containing regimens were associated with more favorable changes in triglyceride and HDL levels than EFV regimens. This benefit could be associated with a reduction in long-term cardiovascular risk; this relationship requires further study.

INTRODUCCIÓN: El tratamiento antirretroviral para VIH genera dislipidemia asociada a riesgo cardiovascular y aterosclerosis. OBJETIVO: Comparar los efectos lipídicos de los antirretrovirales en pacientes con VIH-sida. MÉTODOS: Cohorte retrospectiva. Se comparó el perfil lipídico de los pacientes que recibieron efavirenz (EFV) versus atazanavir (ATV) con una backbone de zidovudina + lamivudina durante 36 meses. RESULTADOS: Se incluyeron 212 pacientes. Desde el inicio hasta los 36 meses, el aumento del HDL del grupo de pacientes en tratamiento con ATV fue mayor en comparación con el que presentaron los pacientes con EFV (8.33 versus 4.26, respectivamente; p < 0.01); se observó una diferencia de triglicéridos entre los grupos, con disminución de 19.06 mg/dL en los pacientes con ATV y aumento de 40.62 mg/dL en los que recibieron EFV (p < 0.001). La diferencia de medias en el cambio de colesterol total y LDL entre ambos tratamientos no fue significativa (p = 0.32 y p = 0.951, respectivamente). CONCLUSIONES: Los regímenes con ATV se asociaron a cambios más favorables en los niveles de triglicéridos y HDL que los regímenes con EFV, relación que podría asociarse a reducción del riesgo cardiovascular a largo plazo, la cuál requiere estudios adicionales.

RESUMO

Os antirretrovirais (ARV) modificaram a evolução natural da síndrome da imunodeficiência adquirida de um quadro inicialmente com perspectiva fatal para doença de convivência crônica, com sobrevida que pode ser próxima daquela esperada para a pessoa hígida. A administração dos ARV, entretanto, requer vigilância médica, não só do especialista, mas de todos os envolvidos na Atenção Básica, na Unidade de Pronto Atendimento e na Terapia Intensiva, para que seus efeitos adversos sejam reconhecidos e abordados convenientemente, o que significará melhores condições de vida para os portadores do vírus da imunodeficiência humana (VIH). Este relato mostra os riscos de associação de ARV, e alerta para situações limites em que alterações metabólicas graves, como acidemia e hipopotassemia, podem colocar em risco a vida do paciente sob terapia ARV

Antirretrovirals (ARV) are medications that have modified the natural evolution of acquired immunodeficiency syndrome from a disease initially with fatal perspective to a chronic coexisting desease, with survival that may be close to that expected for the healthy person. Its administration, however, requires medical supervision, not only of the specialist, but of all those involved in basic care, in the emergency care unit and in the intensive care unit, so that its adverse effects are recognizeed and approached conveniently, which will mean better living conditions for human immunodeficiency vírus (HIV) carriers. This report shows the risk of ARV association, and alerts to limiting situations in whick serious metabolic changes, such as acidemia and hypokalemia, may endanger the lives of patients on ARV therapy.

Objetivo: Identificar el nivel de adherencia a la TARGA en personas con VIH/sida de un área de salud y algunas variables relacionadas. Material y Métodos: Estudio descriptivo realizado en 153 pacientes de 18 y más años, con diagnóstico de VIH/sida, del Policlínico "Marcos Manduley", municipio Centro Habana, de enero a diciembre de 2018. La fuente de datos fueron las historias clínicas individuales y se aplicó el cuestionario SMAQ para complementar la información. Se utilizó la prueba de Chi cuadrado ((2) con significación estadística, ɒ = 0,05, se identificaron variables cuyos coeficientes fueron significativamente diferentes de 0 (p < 0,05) y el grado de correlación entre variables utilizando el coeficiente tau-b de Kendall. Resultados: El 70,5 por ciento tuvo buena adherencia a la TARGA. Se encontró asociación estadística y moderada relación directa entre la adherencia terapéutica y la menor edad de los pacientes, débil relación directa con el mayor tiempo bajo tratamiento y ligera relación directa con la presencia de reacciones adversa. Conclusiones: El estudio permitió identificar que el nivel de adherencia terapéutica a la TARGA fue adecuado, usando el cuestionario SMAQ y se relaciona con algunas variables, resultados que concuerdan con otros estudios consultados(AU)

ABSTRACT Introduction: The prevalence of therapeutic adherence to highly active antiretroviral treatment (HAART) is a complex process influenced by multiple factors related to the patient, the disease, the drug, the environment and the doctor. Objective: To identify the level of adherence to HAART and some related variables in people with HIV / AIDS in a health area. Material and Methods: A descriptive study was carried out in 153 patients aged 18 and over with HIV / AIDS diagnosis that received medical assistance at "Marcios Manduley" Polyclinic in Centro Habana municipality from January to December 2018. Data were obtained from individual medical records; the simplified medication adherence questionnaire (SMAQ) was applied to complement the information. The Chi-square test ((2) was used with statistical significance, p = 0.05; variables whose coefficients were significantly different from 0 (p <0.05) were identified and the degree of correlation between variables was obtained using Kendall's correlation coefficient. Results: The results show that 70.5 percent of people had good adherence to HAART. There was statistical association and moderate direct relationship between therapeutic adherence and younger age patients, weak direct relationship with the longest duration of treatment and a slight direct relationship with the presence of adverse reactions. Conclusions: The study allowed us to identify that the level of therapeutic adherence to HAART was adequate using the SMAQ questionnaire. It is related to some variables, showing results that are consistent with other studies consulted(AU)

RESUMO

ABSTRACT Background: Antiretroviral therapy (ART) has decreased AIDS incidence and mortality, rendering comorbidities, such as hepatitis B more relevant for people living with human immunodeficiency virus (HIV). Since antiretroviral drugs may also inhibit hepatitis B virus (HBV) replication, analyzing the impact of ART on management of hepatitis B in this population is important. Objective: To assess HBV viremia among HIV/HBV coinfected individuals on ART and its associated factors. Method: For this cross-sectional study, HIV/HBV-coinfected individuals, aged over 18 years, who were on ART for over six months and receiving care at an outpatient clinic in São Paulo were recruited. Sociodemographic characteristics, information about viral exposure, clinical and laboratory data, including evaluation of liver fibrosis were obtained. Plasma HBV DNA was measured by polymerase chain reaction. Viral genome sequencing was conducted for genotyping and identification of drug resistance-conferring mutations if viral load exceeded 900 IU/mL. Results: Out of 2,946 patients who attended the clinic in 2015, 83 were eligible and 56 evaluated. Plasma HBV DNA was detected in 16 (28.6%) (95% CI: 18.0-41.3%), all on lamivudine and tenofovir treatment. HBV DNA detection was associated with lower education (p = 0.015), higher international normalized ratios (p = 0.045), history of an AIDS-defining illness [OR: 3.43 (95% CI: 1.10-11.50)], and HBeAg detection [OR: 6.60 (95% CI: 1.84-23.6)]. In contrast, a last CD4+ count above 500 cells/mm3 in the year prior to inclusion [OR: 0.18 (95% CI: 0.04-0.71)] and detection of anti-HBe [OR: 0.21 (95% CI: 0.04-0.99)] were negatively associated. Patients with HBV DNA above 900 IU/mL were infected with subgenotypes A1 (n = 3) and D2 (n = 1), and exhibited viral mutations associated with total resistance to lamivudine and partial resistance to entecavir. Conclusions: Despite being on ART, a significant proportion of HIV/HBV-coinfected individuals present HBV viremia. Characterization of factors that are associated with this finding may help professionals provide better management to these patients.

RESUMO

Resumen Introducción: La farmacocinética de los anti-retrovirales (ARVs) puede ser modificada por otros medicamentos de uso concomitante. Es oportuno actualizar las interacciones entre nuevos ARVs y fármacos de uso crónico para mantener un éxito terapéutico. Objetivo: Actualizar información sobre interacciones medicamentosas en pacientes con infección por VIH/SIDA en terapia antiretroviral. Método: Revisión estructurada en MEDLINE/ PubMed utilizando los términos Mesh: Anti-retroviral agents and drug interactions or herb-drug interactions or food-drug interactions, entre enero de 2015 y junio de 2017. Fueron seleccionadas publicaciones sobre interacciones medicamentosas en humanos, en inglés o español y con acceso a texto completo. Además, se incluyeron referencias de artículos considerados relevantes. La inclusión de los artículos fue evaluada por tres investigadores independientes y, en caso de requerirlo, por consenso entre ellos. La relevancia clínica se estableció, acorde con la gravedad y probabilidad de ocurrencia de la interacción. Resultados: Se identificaron 466 artículos, se accedió a texto completo a 444. De éstos, 164 aportaron interacciones, lo que permitió identificar un total de 534 parejas de interacciones medicamentosas. Las interacciones que presentaron un mayor riesgo de generar problemas de seguridad y efectividad fueron 308 (57,7%) de nivel 2 y 35 (6,6%) de nivel 1. Conclusiones: Se identifican 534 parejas nuevas de interacciones medicamentosas, de ellas 308 (64,2%) de mayor relevancia clínica.

It is timely to update the interactions between new ARVs and drugs of chronic use to maintain therapeutic success. Aim: To update information about drug interactions in patients with HIV/AIDS on antiretroviral therapy. Methods: Comprehensive literature review in MEDLINE/PubMed database from January of 2015 to June of 2017, using the Mesh terms: Anti-retroviral agents and drug interactions or herb-drug interactions or food-drug interactions. Publications with drug interactions in humans, in English or Spanish, and with full text were retrieved. Additionally, citation lists from identified articles were reviewed. The study inclusion was assessed by three independent researchers and by consensus among them when was necessary. Clinical relevance of drug interaction was grouped into levels according to seriously and probability of occurrence. Results: 466 articles were identified; full text was accessed in 444. Of these, 164 provided interactions, which allowed the identification of a total of 534 pairs of drug interactions. The interactions that presented a higher risk of generating safety and effectiveness problems were 308 (57.7%) of level 2 and 35 (6.6%) of level 1. Conclusions: We identify 534 new pairs of drug interactions, of which 308 (64.2%) are the most clinically relevant.

RESUMO

A exposição ocupacional a material biológico com risco de transmissão do vírus da imunodeficiência humana (HIV) constitui uma emergência médica. A profilaxia pós-exposição (PEP) deve ser iniciada precocemente e mantida por 28 dias. Desde julho de 2015, o Ministério da Saúde passou a recomendar o uso combinado de três drogas antirretrovirais para a PEP, menos tóxicas e melhor toleradas do que as usadas anteriormente. Apesar disso, quase metade dos expostos em uso da PEP apresenta efeitos adversos. Geralmente, eles são leves e autolimitados. Os mais comuns são alterações gastrointestinais, astenia, cefaleia e tontura. Entretanto, eventos mais graves já foram observados e a taxa de interrupção da profilaxia permanece elevada. Em 2017, o Ministério da Saúde modificou o esquema de primeira linha da PEP, substituindo o terceiro antirretroviral. Esse artigo relata um caso de toxicidade associada ao uso da PEP após exposição ocupacional a material biológico contaminado pelo HIV, traz a revisão dos potenciais efeitos adversos das drogas antirretrovirais que compõem o esquema profilático preconizado pelo Ministério da Saúde e discute a conduta do médico do trabalho diante dessas complicações.

Occupational exposure to biological materials involving risk of human immunodeficiency virus (HIV) transmission is a medical emergency. Post-exposure prophylaxis (PEP) should be started early and administered for 28 days. Since July 2015, the Brazilian Ministry of Health recommends the combined use of three antiretroviral drugs for PEP, which are less toxic and better tolerated than the ones previously used. Nevertheless, almost half of the exposed individuals under PEP exhibit adverse effects, which are usually mild and self-limited. The most frequent adverse events are gastrointestinal disorders, asthenia, headache and dizziness. However, more severe events have been reported, and the rate of non-completion of prophylaxis remains high. In 2017, the Brazilian Ministry of Health modified the first-line PEP regimen involving replacement of the third antiretroviral drug. The present article reports a case of toxicity associated with PEP following an occupational accident involving exposure to HIV infected biological material. In addition, we review the potential adverse effects of antiretroviral drugs included in the prophylactic regimens recommended by the Brazilian Ministry of Health and discuss measures occupational physicians should adopt vis-à-vis these complications

RESUMO

BACKGROUND: Low molecular weight 1-Aryl-1H-1,2,3-triazoles are endowed with various types of biological activities, such as against cancer, HIV and bacteria. Despite the existence of six different classes of antiretroviral drugs in clinical use, HIV/AIDS continue to be an on growing public health problem. OBJECTIVE: In the present study, we synthesized and evaluated thirty 1-Aryl-1H-1,2,3-triazoles against HIV replication. METHOD: The compounds were prepared by Huisgen 1,3-dipolar cycloaddition protocol catalyzed by Cu(I) between aryl azides and propargylic alcohol followed by further esterification and etherification from a nucleophilic substitution with acid chlorides or alkyl bromides in good yields. The compounds were submitted to the inhibition of HIV replication and evaluation of their cytotoxicity. Initially, the compounds were screened at 10 µM and the most active were further evaluated in order to obtain some pharmacological parameters. RESULTS: Thirty molecules were evaluated, six were selected - because they inhibited more than 80% HIV replication. We further showed that two of these compounds are 8-times more potent, and less cytotoxic, than nevirapine, an antiretroviral drug in clinical use. CONCLUSION: We identified very simple triazoles with promissing antiretroviral activities that led to the development of new drugs against AIDS.

RESUMO

Resumen Los cambios en la densidad mineral ósea (DMO) son comunes en adultos infectados con virus de la inmunodeficiencia humana (VIH). Existen pocos estudios que evalúen el compromiso óseo en niños. Objetivo: Evaluar la DMO en niños infectados verticalmente por VIH. Métodos: Se estudiaron 53 niños infectados (8-18) de cinco hospitales. Se registró severidad de enfermedad, evaluación nutricional, vitamina D (25-OHD) y estado inmunológico. La DMO se midió mediante densitometría. Se utilizó análisis descriptivo, comparación de medias y regresión lineal simple y múltiple. Resultados: El 88,7% estaban en estadio B y C, 57% eran eutróficos y 18,9% tenían talla baja. El 33,3% presentaba niveles de 25-OHD < 20 ng/ml. El 11%, 6% y 4% de los niños tenían DMO < 2DE en cadera, columna y cuerpo entero, respectivamente. La DMO se correlacionó con IMC, talla, severidad de enfermedad y años de tratamiento. Sólo inhibidores de las proteasas (IP) mantuvieron su significancia al ajustar por otras variables. Conclusión: Los niños infectados con VIH tuvieron DMO más baja por edad comparados con datos de NHANES III. La severidad de la enfermedad, talla, zIMC, los años de tratamiento con anti-retrovirales, principalmente IP, están relacionados con la reducción de la masa ósea.

Changes in bone mineral density (BMD) are common in adults infected with human immunodeficiency virus (HIV). There are few studies evaluating bone involvement in children infected. Objective: To evaluate BMD in vertically HIV-infected children. Methods: We studied 53 infected children (8-18 years) from five hospitals. Disease status, nutritional assessment, vitamin D (25-OHD) levels and immunological status were recorded. BMD was measured by densitometry. Descriptive analysis, comparison of means and simple and multiple linear regression were used. Results: 88.7% children were in stage B and C, 57% were eutrophic and 18.9% had short stature. 33.3% had 25-OHD levels < 20 ng / ml. 11%, 6% and 4% of the children had BMD <-2DE in hip, spine and whole body respectively. BMD was correlated with BMI, height, disease stage and years of treatment. Only protease inhibitors (PIs) maintained their significance when adjusted for other variables. Conclusion: children infected with HIV had lower BMD by age compared to NHANES III data. The severity of the disease, height, zBMI, years of treatment with antiretrovirals, mainly IP, are related to the reduction of bone mass.

RESUMO

Purpose: To verify the effectiveness of a pharmaceutical care model developed by the Specialized Municipal Assistance Service in Sorocaba, Brazil, on adherence to ART among patients infected with HIV. Methods: A cohort study compared adherence to ART in two groups of patients: intervention group (patients assisted with pharmaceutical care, n=130) and non-intervention group (patients attended by the habitual dispensing process, n=229). Antiretroviral adherence was measured by the number of pharmacy refill records in a six-month period. The relationship between the use of other drugs for the treatment of opportunistic infections and the adherence rate in the intervention group and the correlation between adherence and viral load and CD4 lymphocytes were also assessed. Results: Higher adherence rates were observed in the intervention group (p<0.05). The use of others drugs did not influence adherence to ART (p=0.30). There was a positive correlation between adherence and the percentage of patients in the intervention group with undetectable viral loads (p=0.0004) and higher levels of CD4 lymphocytes (p=0.0024). Conclusion: The pharmaceutical care model developed by the SAME improved patient adherence to ART as well as clinical outcomes.

RESUMO

Viruses exhibit rapid mutational capacity to trick and infect host cells, sometimes assisted through virus-coded peptides that counteract host cellular immune defense. Although a large number of compounds have been identified as inhibiting various viral infections and disease progression, it is urgent to achieve the discovery of more effective agents. Furthermore, proportionally to the great variety of diseases caused by viruses, very few viral vaccines are available, and not all are efficient. Thus, new antiviral substances obtained from natural products have been prospected, including those derived from venomous animals. Venoms are complex mixtures of hundreds of molecules, mostly peptides, that present a large array of biological activities and evolved to putatively target the biochemical machinery of different pathogens or host cellular structures. In addition, non-venomous compounds, such as some body fluids of invertebrate organisms, exhibit antiviral activity. This review provides a panorama of peptides described from animal venoms that present antiviral activity, thereby reinforcing them as important tools for the development of new therapeutic drugs.

RESUMO

To determine the frequency of Enamel Development Defects (DDE) and associated factors in children and adolescents infected with HIV. A case-control study was conducted in HIV-infected patients (n = 52), aged 3 to 15, and a control group formed by preschool and schoolchildren (n = 104) matched according to gender, age and household income. Data on medical history, neonatal and maternal conditions were obtained. For diagnosis of enamel defects was used modified DDE Index. DDE frequency was 61.5% in the case group and 58.7% in the control group (p = 0.569). Infection of the genitourinary tract and maternal hemorrhage were factors associated with DDE in the case and control groups, respectively. An association was observed between the use of antiretroviral regimens with protease inhibitors or efavirenz and DDE in the permanent dentition. Children and adolescents HIV-infected showed a DDE frequency similar to healthy patients, but factors associated with this condition were different between the groups.

RESUMO

BACKGROUND: Highly active antiretroviral therapy has extended the expected lifespan of patients with HIV/AIDS. However, the therapeutic benefits of some drugs used simultaneously with highly active antiretroviral therapy may be adversely affected by drug interactions. OBJECTIVE: The goal was to design and develop a free software to facilitate analysis, assessment, and clinical decision making according to the clinical relevance of drug interactions in patients with HIV/AIDS. METHODS: A comprehensive Medline/PubMed database search of drug interactions was performed. Articles that recognized any drug interactions in HIV disease were selected. The publications accessed were limited to human studies in English or Spanish, with full texts retrieved. Drug interactions were analyzed, assessed, and grouped into four levels of clinical relevance according to gravity and probability. Software to systematize the information regarding drug interactions and their clinical relevance was designed and developed. RESULTS: Overall, 952 different references were retrieved and 446 selected; in addition, 67 articles were selected from the citation lists of identified articles. A total of 2119 pairs of drug interactions were identified; of this group, 2006 (94.7%) were drug-drug interactions, 1982 (93.5%) had an identified pharmacokinetic mechanism, and 1409 (66.5%) were mediated by enzyme inhibition. In terms of clinical relevance, 1285 (60.6%) drug interactions were clinically significant in patients with HIV (levels 1 and 2). With this information, a software program that facilitates identification and assessment of the clinical relevance of antiretroviral drug interactions (SIMARV®) was developed. CONCLUSIONS: A free software package with information on 2119 pairs of antiretroviral drug interactions was designed and developed that could facilitate analysis, assessment, and clinical decision making according to the clinical relevance of drug interactions in patients with HIV/AIDS.
