RESUMO

BACKGROUND: The incidence of comorbidities is higher in HIV-positive patients than in the general population due to factors, such as HIV-related chronic inflammation. There is no consensus on whether a low CD4 lymphocyte count after virological suppression at long-term follow-up increases the risk of comorbidities. This study evaluates the association between CD4 lymphocyte count and the incidence of comorbidities during the first 5 years of virological suppression after highly active antiretroviral treatment. METHODS: We conducted a cohort study of HIV-positive adults who achieved virological suppression in an HIV program between 2002 and 2016 in Colombia. A generalized equation estimation model was used to estimate the association between CD4 lymphocyte count and the incidence of comorbidities. RESULTS: A follow-up period of at least 1 year was completed in 921 HIV-positive patients with virological suppression. We found 71 comorbidities during a maximum of 5 years of follow-up; 41 (59%) were AIDS-defining comorbidities and 19 (46%) of them occurred during the first semester. Thirty cases of non-AIDS- defining comorbidities were diagnosed.We did not find any association between CD4 lymphocyte count and the incidence of comorbidities (OR 0.92, CI 95% 0.45 -1.91 for CD4 201-499 cells/µL vs CD4 ≤200 cells/µL, and OR 0.55, 95% CI 0.21-1.44 for CD4 ≥500 cells/µL vs CD4 ≤200 cells/µL). CONCLUSION: No association was found between CD4 lymphocyte count and the incidence of AIDS-defining or non-AIDS-defining comorbidities in patients with virological suppression. Further studies are needed to assess the risk of comorbidities in this population to design interventions aimed at improving their prognosis.

RESUMO

BACKGROUND: In the first reported cases of human immunodeficiency virus (HIV) infection, people living with HIV (PLHIV) suffered weight loss, which was an independent predictor of mortality. Highly active antiretroviral therapy (HAART) has changed this scenario for ideal weight, overweight, and even obesity. However, some PLHIV, even on HAART, continue to lose weight. Thus, the guiding question of the study was: do PLHIV hospitalized using HAART with weight loss have higher mortality than hospitalized PLHIV using HAART without weight loss? METHOD: A systematic review and meta-analysis of prospective cohort studies published in English, Spanish, or Portuguese, searched in the MedLine, Embase, and LILACS databases from March 2020, until October 2023, reported by MOOSE. We analyzed the methodological quality and risk of bias using the Joanna Briggs Institute Critical Appraisal Tool for Cohort Studies; used the risk ratio (RR) to calculate the probability of hospitalized PLWH who lost weight dying, applied the random effect model and created the funnel plot. We used the inverse variance test estimated by the Mantel-Haenszel method, considering a 95% confidence interval (CI), heterogeneity (I2), total effect size (Z), and significance value of p < 0.05. We performed a sensitivity analysis with meta-regression and meta-analyses on subgroups to diagnose influence and outliers. The quality of evidence and strength of recommendation were analyzed using the Grading of Recommendations Assessment, Development, and Evaluation system (GRADE). RESULTS: We included 10 of the 711 studies identified, totaling 1,637 PLHIV. The studies were from South Africa (1), Canada (1), China (1), Brazil (1), Cameroon (1), Ethiopia (1), Thailand (1), Colombia (1), and Tanzania (2), from 1996 to 2017. The average age of the participants was 33.1 years old, and the male was predominant. The leading causes of hospital admission were related to co-infections, and the average hospitalization time was 20.5 days. The prevalence of death in hospitalized PLHIV using HAART who lost weight was 57.5%, with a 1.5 higher risk of dying (RR: 1.50, 95% CI: 1.03, 2.19, p = 0.04) than hospitalized PLHIV who did not lose weight. CONCLUSION: We concluded, with a very low confidence level, that that weight loss significantly increased the risk of death in hospitalized PLWH using HAART.

RESUMO

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.

RESUMO

OBJECTIVE: To evaluate the association between Highly Active Antiretroviral Therapy (HAART) discontinuation time and therapeutic failure (TF) in Venezuelan immigrants with HIV that restart HAART. METHODS: We carried out a retrospective cohort study in a large hospital in Peru. We included Venezuelan immigrants who restarted HAART and were followed over at least 6 months. The primary outcome was TF. Secondary outcomes were immunologic (IF), virologic (VF) and clinical (CF) failures. The exposure variable was HAART discontinuation, categorised as no discontinuation, less than 6 months, and 6 months or more. We applied generalised linear models Poisson family with robust standard errors to calculate crude (cRR) and adjusted (aRR) relative risks by statistical and epidemiological criteria. RESULTS: We included 294 patients, 97.2% were males, and the median age was 32 years. Out of all the patients, 32.7% discontinued HAART for less than 6 months, 15.0% discontinued for more than 6 months and the remaining 52.3% did not discontinue. The cumulative incidence of TF was 27.9%, 24.5% in VF, 6.0% in IF and 6.0% in CF. Compared with non-discontinued HAART patients, the discontinuation for less than 6 months (aRR = 1.98 [95% CI: 1.27-3.09]) and from 6 months to more (aRR = 3.17 [95% CI: 2.02-4.95]) increased the risk of TF. Likewise, treatment discontinuation of up to 6 months (aRR = 2.32 [95% CI: 1.40-3.84]) and from 6 months to more (aRR = 3.93 [95% CI: 2.39-6.45]) increased the risk of VF. CONCLUSIONS: HAART discontinuation increases the probability of TF and VF in Venezuelan immigrants.

RESUMO

Despite solid scientific evidence, the concepts of treatment as prevention (TASP) and Undetectable = Untransmittable (U = U) remain unfamiliar and underutilized for some healthcare providers. We conducted a self-completion survey to evaluate the knowledge of TASP/U = U in different medical specialties. Wilcoxon Rank-Sum, Chi-square and Fisher's exact tests were used for group comparisons and a logistic regression model was used to assess factors independently associated with U = U-non-supportive attitudes. 197 physicians were included; 74% agreed/strongly agreed that people living with HIV (PLHIV) under regular treatment with undetectable viral do not transmit HIV sexually. However, only 66% agree/strongly agree that PLHIV should be informed about that. The knowledge about these concepts was poorer among gynecologists, urologists and internal medicine specialists when compared to infectious diseases specialists after adjustment for age, race/skin color, gender, and sexual orientation. Our study found that knowledge of crucial concepts of HIV prevention may be lacking for some medical specialties. This highlights the need of improvement in medical education.

RESUMO

Aim: To adapt and validate an existing instrument to assess the barriers to antiretroviral treatment adherence among individuals with hiv in Córdoba, Argentina. Materials and methods: The final sample population included 180 Argentinian people. The mean age of the participants was 40.61 (sd = 12.032) years and 82.8% were men. Various internal structure and reliability and validity studies with other variables were conducted on the study population (n = 180). Results: The results of confirmatory factor analysis were consistent with the factorial structure of the original study. However, to achieve this, items that had low factorial loads and were redundant had to be eliminated. Coefficient ω values of .833 on the Information sub-scale, .759 on the Motivation subscale, and .888 on the Behavioral Skills subscale were obtained. Significant correlations were determined between the results of adherence and barriers to treatment. Conclusion: The results suggest that the instrument can be used to assess the barriers to antiretroviral treatment adherence in Córdoba, Argentina. Although further research is warranted, these results are promising.

RESUMO

BACKGROUND: There is scarce information on AIDS-related cytomegalovirus (CMV) retinitis in middle-income countries. The objectives of this study were to identify the prevalence of active CMV retinitis in severely immunosuppressed people living with HIV (PLWHIV) and to describe its main features. METHODS: This retrospective cohort study was carried out at a tertiary center in São Paulo, Brazil. We included hospitalized adults PLWHIV with CD4 count ≤100 cells/µL, ≥ one quantitation of CMV DNA in plasma, and indirect ophthalmoscopy evaluation. RESULTS: Thirty-eight (21.6%) of 176 participants had at least an ophthalmoscopy diagnosis and only 3 (1.7%) individuals presented active CMV retinitis. All these participants were male, and retinitis was asymptomatic in 2 cases. Two participants had extraocular end-organ CMV disease and detectable CMV DNA in plasma. CONCLUSIONS: These results show a low prevalence of active CMV retinitis in the evaluated population. However, 2 of 3 participants had asymptomatic active CMV retinitis and a fifth of participants had at least one ophthalmoscopy diagnosis, suggesting the need for routine ophthalmologic evaluation in hospitalized severely immunosuppressed PLWHIV. The profile of participants with active CMV retinitis was similar to that described in the pre-ART era and quantitation of CMV DNA in plasma was variable.

RESUMO

BACKGROUND: AIDS-related cytomegalovirus (CMV) encephalitis has declined in the combined antiretroviral therapy (ART) era in high-income countries. However, there is scarce information on CMV encephalitis in low- and middle-income countries. The objectives of this study were to identify the prevalence of AIDS-related CMV encephalitis and describe its main features. METHODS: This was a retrospective cohort study carried out at a referral center in São Paulo, Brazil. We included adult people living with HIV/AIDS (PLWHA), hospitalized in 2019, with a CD4 cell count ≤100/mm3 and quantitation CMV DNA results in plasma. Cases with compatible neurological manifestations and detection of CMV DNA by polymerase chain reaction (PCR) in cerebrospinal fluid samples were defined as CMV encephalitis. RESULTS: Among 761 PLWHA hospitalized, 248 (32.5%) cases were included in this study. Prevalence of CMV encephalitis was 2.4% (6/248) among all included cases and 7.7% (6/78) among individuals with neurological opportunistic diseases. The six patients with CMV encephalitis were males and had CD4 cell count <50/mm3. Five (83%) cases had CMV encephalitis as AIDS-defining disease and showed CMV DNA detection by PCR >50,000 UI/mL plasma. All six cases received anti-CMV therapy (ganciclovir, n = 4; ganciclovir plus foscarnet, n = 2) and five were discharged to home. CMV encephalitis was not uncommon among hospitalized PLWHA with neurological opportunistic diseases. CONCLUSIONS: The epidemiological and immunological profile of individuals with CMV encephalitis was similar to that described in the pre-ART era, but in contrast, most cases were treated and discharged from the hospital.

RESUMO

BACKGROUND: HIV infection continues to be a global public health challenge, affecting approximately 1.7 million reproductive-aged women. Protease inhibitor-based highly active antiretroviral therapy (PI-HAART) has significantly reduced the risk of vertical transmission of HIV from mother to child. Nevertheless, concerns linger regarding the long-term effects, particularly on body composition, notably subcutaneous fat tissue (SFT). Although HIV-associated lipodystrophy syndrome (LS) has been well documented in adults and older children, its impact on fetuses exposed to PI-HAART remains underexplored. This study aims to evaluate SFT in the fetuses of HIV-pregnant women exposed to PI-HAART, assessing the potential clinical implications. METHODS: We conducted a comparative study between HIV-pregnant women receiving PI-HAART and an HIV-negative control group. Fetometry measurements were obtained via 3D ultrasound. SFT in the fetal arm and thigh segments was assessed. Data were analyzed using lineal multivariate regression and receiver-operating characteristics (ROC)-curve analysis. RESULTS: Fetuses exposed to PI-HAART exhibited a significant reduction in subcutaneous fat, particularly in the proximal third-middle union of the femur (coefficient: -2.588, p = 0.042). This reduction was correlated with lower newborn serum glucose levels (65.7 vs. 56.1, p = 0.007; coefficient: -1.277, p = 0.045). CONCLUSIONS: Our study sheds light on the connection between PI-HAART, fetal subcutaneous fat, and neonatal health. These findings might reveal the long-lasting effects of PI-HAART on newborns and children's well-being. Our results emphasize the need for a more balanced approach to managing pregnant women with HIV in developing countries and open new venues for research on the impact of intrauterine PI-HAART exposure on energy metabolism and fetal programming.

RESUMO

A adesão à terapia antirretroviral (TARV) é fundamental para obter o controle da infecção por HIV, evitando complicações clínicas e o desenvolvimento de cepas de HIV resistentes. Vários municípios brasileiros estão comprometidos com a meta 90-90-90, que prevê que 90% dos casos de HIV/aids sejam diagnosticados, que 90% destes estejam em tratamento e, destes, 90% alcancem a supressão viral. Entretanto, existem apenas três estudos brasileiros que avaliam a adesão à TARV a partir de dados secundários de dispensação. Este estudo objetivou estimar a prevalência de adesão ao tratamento no Município de Florianópolis, Santa Catarina, Brasil, examinando sua associação com aspectos demográficos, de utilização de saúde e características clínicas. Realizou-se um estudo transversal com o uso de dados secundários do prontuário eletrônico e dados nacionais, dos Sistema de Controle Logístico de Medicamentos (SICLOM) e Sistema de Controle de Exames Laboratoriais (SISCEL), de pessoas vivendo com HIV/aids no município de abril de 2020 a março de 2021. A prevalência de adesão à TARV foi de cerca de 85%. Pessoas brancas, do sexo masculino, que tinham acompanhamento tanto na atenção primária à saúde (APS) quanto na atenção secundária tinham maior adesão ao tratamento. A idade e o número de consultas apresentaram associação direta com adesão à TARV. O processo de descentralização do cuidado ao usuário vivendo com HIV/aids é o caminho para uma assistência mais integral, porém desafios técnicos e éticos ainda precisam ser enfrentados. A qualificação profissional, o correto referenciamento com articulação em rede e a atenção às questões de sigilo e confidencialidade precisam ser reforçadas de forma a ampliar a adesão ao tratamento.

Adherence to antiretroviral therapy (ART) is essential to control HIV infections and avoid clinical complications and the development of resistant HIV strains. Several Brazilian municipalities have committed themselves to the 90-90-90 target, which aims at diagnosing 90% of HIV/AIDS cases, treating 90% of them, and virally suppressing 90% of them. However, only three Brazilian studies have assessed adherence to ART from secondary dispensing data. This study aimed to estimate the prevalence of adherence to treatment in the Municipality of Florianópolis, Santa Catarina State, Brazil, examining its association with demographic, health access, and clinical characteristics. A cross-sectional study was conducted using secondary national data from electronic medical records and Medication Logistic Control System (SICLOM) and Laboratory Test Control System (SISCEL) regarding people living with HIV/AIDS in the municipality from April 2020 to March 2021. We found an about 85% prevalence of adherence to ART. White men with follow-ups both in primary and secondary care showed greater adherence to treatment. Age and number of consultations directly related to adherence. Decentralizing care for users living with HIV/AIDS is the way to more comprehensive care but technical and ethical challenges still require solutions. Professional training, correct network referrals, and attention to confidentiality issues must be reinforced to expand treatment adherence.

La adherencia a la terapia antirretroviral (TARV) es fundamental para controlar la infección por VIH, evitando complicaciones clínicas y el desarrollo de cepas de VIH resistentes. Varios municipios brasileños están comprometidos con la meta 90-90-90, que estima el diagnóstico del 90% de los casos de VIH/SIDA, que el 90% de estos reciban tratamiento y, de estos, el 90% logran llegar a la supresión viral. Sin embargo, solo hay tres estudios brasileños que evalúan la adherencia al TARV con base en datos secundarios sobre la dispensación. Este estudio tuvo por objetivo estimar la prevalencia de adherencia al tratamiento en la ciudad de Florianópolis, Santa Catarina, Brasil y su asociación con aspectos demográficos, uso de la salud y características clínicas. Se realizó un estudio transversal con los datos secundarios de la historia clínica electrónica y los datos nacionales del Sistema de Control Logístico de Medicamentos (SICLOM) y Sistema de Control de Pruebas de Laboratorio (SISCEL) de las personas que viven con VIH/SIDA en ese municipio en el período de abril de 2020 a marzo de 2021. La prevalencia de adherencia al TARV fue casi del 85%. Las personas de raza blanca, del sexo masculino, que recibían seguimiento en la atención primaria o en la atención secundaria tuvieron mayor adherencia al tratamiento. La edad y el número de consultas se asociaron directamente con la adherencia al TARV. El proceso de descentralización de la atención a los usuarios que viven con VIH/SIDA y sida es la forma de brindar una atención más integral, pero aún se deben enfrentar desafíos técnicos y éticos. Es necesario mejorar la calificación profesional, la correcta derivación con articulación en red y tener cuidado al secreto y la confidencialidad para que se intensifique aún más la adherencia al tratamiento.

RESUMO

ABSTRACT Introduction: Hematologic abnormalities are common in HIV and involve all blood cell lineages. A study on cytopenias, as correlated with disease progression, can be valuable in resource-limited settings. This study aimed to determine the hematologic profile of HIV patients and its association with CD4 count and antiretroviral (ARV) treatment. Methods: This is a retrospective cohort study involving adult Filipino HIV patients with complete blood count (CBC) and CD4 count determinations prior to the initiation of ARV treatment and after ≥6 months of ARV treatment. Logistic regression was performed to determine the association between cytopenias and a CD4 count <200 cells/μL. Results: The study included 302 patients. Anemia was the most common cytopenia. Anemia and leukopenia were associated with an increased likelihood of having a CD4 count <200 cells/μL in ARV-naïve patients. In ARV-treated patients, leukopenia was associated with an increased probability of having a CD4 count <200 cells/μL. An increase in hemoglobin, white blood cell (WBC) and platelet counts was observed after ≥6 months of ARV treatment. Conclusion: Anemia and leukopenia can be used as markers of immune status in HIV-infected individuals and improvement in the CBC parameters can be used to assess response to ARV treatment. Routine monitoring of hematologic parameters is recommended.

RESUMO

INTRODUCTION: HIV is still a central public health issue in Latin America, disproportionally affecting key populations. Knowledge and access to biomedical prevention strategies, including treatment as prevention (TASP) or undetectable = untransmissible (U=U), pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP), are the first steps to increasing uptake. We used data from the Latin American MSM Internet Survey (LAMIS) to describe knowledge and access to biomedical HIV prevention strategies among gay, bisexual, transgender and other men who have sex with men (MSM) living in 18 Latin American countries. METHODS: We compared LAMIS data across countries and according to age categories using frequencies and percentages. We also used multivariable models to explore whether age, gender identity, sexual identity, steady partnership, HIV status and education were independently associated with outcomes. RESULTS: In all, 55 924 participants were included. Most were cisgender (99%) and identified as gay/homosexual (77%) or bisexual (17%). Schooling levels were very high, with 89% reporting highest attained education as tertiary level, university or post-graduation. In total, 16% had been previously diagnosed with HIV; of those, rates of undetectable viral load varied from 60% in Venezuela to 83% in Brazil. Overall, 54%, 54% and 52% of participants already knew about PEP, PrEP and U=U, respectively. Participants from Brazil and those aged between 26 and 55 years, living with diagnosed HIV and having a gay/homosexual identity had greater levels of awareness about biomedical prevention strategies. CONCLUSIONS: Our study highlights gaps in HIV prevention campaigns directed to MSM in Latin America resulting in low uptake of biomedical prevention methods.

RESUMO

HIV infection causes a constant activation of the immune system and contributes to an enhanced systemic pro-inflammatory cytokine milieu, which has been associated with premature aging and frailty. We performed a systematic review and meta-analysis to analyze whether the HIV-1 RNA load, CD4+ T-lymphocyte counts and exposure to HAART in HIV-positive subjects are associated with frailty phenotype. Searches were performed in PubMed, SCOPUS, Lilacs, Web of Science, Google Scholar, and OpenThesis databases. We used the odds ratio as a measure of the association. We used either a fixed or random-effects model to pool the results of individual studies depending on the presence of heterogeneity. Eleven studies were included in the review. Data from 8035 HIV-positive subjects were analyzed; 2413 of the subjects had viral load detectable, 981 had a CD4T-cell count <350 cells/µL, and 1342 had HAART exposure information. We found an association between frailty and CD4T-cell count <350 cells/µL (OR 2.68, CI 95% 1.68-4.26, I2 = 46%), HIV-1 RNA load detectable (OR 1.71, CI 95% 1.38-2.12, I2 = 0%), and protease inhibitor-containing HAART regimen (OR 2.21, CI 95% 1.26-3.89, I2 = 0%). Further studies are necessary to evaluate the effects of other factors on the development of clinical features related to frailty.

Logistic regression was performed to determine the association between cytopenias and a CD4 count <200 cells/µL. RESULTS: The study included 302 patients. Anemia was the most common cytopenia. Anemia and leukopenia were associated with an increased likelihood of having a CD4 count <200 cells/µL in ARV-naïve patients. In ARV-treated patients, leukopenia was associated with an increased probability of having a CD4 count <200 cells/µL. An increase in hemoglobin, white blood cell (WBC) and platelet counts was observed after ≥6 months of ARV treatment. CONCLUSION: Anemia and leukopenia can be used as markers of immune status in HIV-infected individuals and improvement in the CBC parameters can be used to assess response to ARV treatment. Routine monitoring of hematologic parameters is recommended.

RESUMO

ABSTRACT Objective: To verify the association between adherence to antiretroviral treatment by adults with HIV/AIDS and sociodemographic factors, social and clinical support. Methods: Cross-sectional study, with a quantitative approach. Participation of 230 patients. Questionnaires of sociodemographic characterization, social and clinical support, and assessment of adherence to antiretroviral treatment were used. Descriptive and inferential statistics were performed. Results: Adherence was classified as good/adequate. An association with sex, income, employment, and level of education was noted. In social support: having access to health services; communication with health professionals; health education; having support to allow venting/talking about issues; information on HIV/AIDS; and company for leisure. In the clinical profile: non-interruption of the drug treatment due to absence from the service or due to changes in the medical prescription. Conclusion: Adherence was classified as good/adequate and especially associated with social support factors, which should be enhanced in clinical practice.

RESUMO

RESUMEN Introducción: El aumento de la expectativa de vida en personas que viven con VIH ha obligado a buscar alternativas de terapia antiretroviral simplificadas y con menor potencial de toxicidad que favorezcan la adherencia, y con ello alcanzar metas de indetectabilidad de la carga viral. Varias alternativas se han propuesto en los últimos años y es necesario saber la efectividad de estas a mediano y largo plazo. Objetivo: Determinar la efectividad y seguridad de la terapia de cambio, en pacientes mayores a 12 años que viven con el virus de la inmunodeficiencia humana. Métodos: Se realizó la búsqueda de la literatura en bases de datos electrónicas y literatura gris. La medida de desenlaces para mantenimiento de carga viral (menos de 50 copias por mililitro), niveles de linfocitos T CD4+ y eventos adversos de la terapia de cambio frente a continuación de la terapia estándar se estimó de forma combinada. Resultados: Se incluyeron seis ensayos clínicos aleatorizados que compararon terapia de cambio (Rilpivirina/Emtricitabina/Tenofovir alafenamida, Dolutegravir/Rilpivirina, Abacavir/Dolutegravir/Lamivudina), frente a la continuación de la terapia estándar. El mantenimiento de la carga viral no fue diferente entre los grupos (OR: 0,77; IC95% 0,59; 1,02), tampoco el recuento de linfocitos T CD4+ (DME: 6;76; IC95% -5,05;18,57), al igual que los eventos adversos serios (OR: 1,03; IC95% 0,74; 1,42). Conclusiones: No se encontró diferencia en la efectividad y seguridad de la terapia de cambio frente a continuar la terapia estándar. Los resultados apoyan en uso de estas estrategias terapéuticas para favorecer la adherencia a la terapia antirretroviral.

ABSTRACT Introduction: Increase in the life expectancy of people living with HIV has led to the search for simplified antiretroviral therapy alternatives of lower toxicity potential which foster adherence and thus contribute to achieve viral load undetectability goals. Several options have been proposed in recent years, and it is necessary to be aware of their mid- and long-term effectiveness. Objective: Determine the effectiveness and safety of switch therapy in patients aged over 12 years who live with the human immunodeficiency virus. Methods: A bibliographic search was conducted in electronic databases and the gray literature. Combined estimation was made of the measure of outcomes for viral load maintenance (less than 50 copies per milliliter), CD4+ T lymphocyte levels and adverse events of switch therapy versus continuing standard therapy. Results: Six randomized clinical trials were included which compared switch therapy (rilpivirine / emtricitabine / tenofovir alafenamide, dolutegravir / rilpivirine, abacavir / dolutegravir / lamivudine) with continuing standard therapy. Viral load maintenance was not different between the groups (OR: 0.77; CI 95% 0.59, 1.02), nor was there any difference in the CD4+ T lymphocyte count (DME: 6.76; CI 95% -5.05;18.57) or the serious adverse events (OR: 1.03; CI 95% 0.74; 1.42). Conclusions: Differences were not found in the effectiveness and safety of switch therapy versus continuing standard therapy. Results support the use of these therapeutic strategies to foster adherence to antiretroviral therapy.

RESUMO

ABSTRACT: Aims: To identify the frequency in changes of bone metabolism, including below the average value for age, osteopenia, and osteoporosis, in people living with HIV/AIDS (PLWHA) and to compare the frequency of factors associated with bone mineral density (BMD) and body composition between sex. Methods: This observational study assessed 106 PLWHA (65 male) recruited from the University Hospital of Ribeirão Preto Medical School from 2013 to 2014. BMD was measured using Dual Energy X-ray Absorptiometry (DXA). Standard deviation values for Z- and T-score proposed by the International Society for Clinical Densitometry were adopted to classify participants below the average value for age, osteopenia, and osteoporosis. Qui-square and Fischer's exact tests were employed to compare males and females based on their factors associated with BMD reduction. Results: Fifty-two (49%) PLWHA presented at least one diagnosis for below the average value for age, osteopenia, and osteoporosis, being 37 (57%) and 15 (37%) male and female, respec-tively. Frequency of alcohol consumption was higher in males (n=20; 30.8%) than females (n=05; 12.2%) (p=0.028).Conclusions: A high rate of PLWHA showed changes in bone metabolism, with a higher frequency in males. The fre-quency of alcohol consumption was higher in males, and it may partially explain the possible causes of the increased rates of bone metabolism changes observed in this group. This information may help develop strategies for reducing the frequency of diagnosis for below the average value for age, osteopenia, osteoporosis improving quality of life in PLWHA. (AU)

RESUMO: Objetivos: Identificar a frequência de alterações no metabolismo ósseo, incluindo valores abaixo do estimado para idade, osteopenia e osteoporose, em pessoas vivendo com HIV/Aids (PVHA) e comparar a frequência de fatores associados à redução da densidade mineral óssea (DMO) e composição corporal entre sexos. Métodos: Estudo observacional que ava-liou 106 PVHA (65 do sexo masculino) recrutadas do Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo entre os anos 2013 e 2014. A DMO foi medida utilizando a Absorciometria Radiológica de Dupla Energia (DXA). Valores de desvio padrão Z- e T- scores propostos pela Sociedade Internacional para Densitometria Clí-nica foram adotados para classificar os participantes em abaixo do valor estimado para idade, osteopenia e osteoporose. Os testes do qui-quadrado e exato de Fischer foram empregados na comparação entre os sexos baseado em seus respec-tivos fatores associados à redução da densidade mineral óssea. Resultados: Cinquenta e dois (49%) PVHA apresentaram ao menos um diagnóstico para abaixo do valor estimado para idade, osteopenia e osteoporose, sendo 37 (57%) do sexo masculino e 15 (37%) feminino. A frequência de consumo de álcool foi maior no sexo masculino (n=20; 30,8%) compara-do ao feminino (n=5; 12,2%) (p=0,028). Conclusões: Uma alta taxa de PVHA apresentaram alterações no metabolismo ósseo, com maior frequência no sexo masculino. A frequência no consumo de álcool foi maior no sexo masculino, podendo explicar parcialmente as possíveis causas para taxa aumentada de alterações no metabolismo ósseo observada nesse grupo. Essa informação pode contribuir no desenvolvimento de estratégias para redução da frequência do diagnóstico para valores abaixo do estimado para idade, osteopenia e osteoporose, melhorando a qualidade de vida em PVHA

RESUMO

AIM OF THE STUDY: To examine mortality trends in children under 15 years of age due to HIV/AIDS in Mexico and describe their differences by insurance coverage. METHODS: Time series analysis of deaths from 1990-2019 through a Bayesian poisson regression model with linear splines and knots in 1994, 1997, and 2003. RESULTS: Overall, we observed a reduction in the mortality rate due to HIV from 2003 onwards, except in the group of 10-14 years. In the population covered with Social Security, mortality rates decreased in all age groups. However, in the group without Social Security or with Popular Security (subsidized system), mortality rates significantly decreased only for children below 5 years. of age. CONCLUSIONS: Health insurance through the contributory system is associated with faster and larger reductions in HIV related infant mortality. Universal access to health insurance was not sufficient to close the gap in HIV-mortality among children under 15 years of age in Mexico.

RESUMO

BACKGROUND: Clinical improvements following highly active antiretroviral therapy (HAART) may increase high-risk behaviors resulting in sexually transmitted infections (STI). Optimism related to the success of HAART in slowing disease progression, reducing viral load, and improving health status might be important factors for increasing sexual risk behaviors such as less use of condoms. OBJECTIVE: To determine the prevalence of Chlamydia trachomatis, Neisseria gonorrhoeae, syphilis, hepatitis B and C, high-risk HPV, and cervical cytological abnormalities among women living with HIV (WLHIV) who attended a Reference Center for STI/AIDS in Brazil. METHODS: A cross-sectional study was conducted among 151 WLHIV attending an STI Clinic in Vitória city, Brazil. A structured questionnaire, including demographic, behavioral, and clinical information, was used for data collection. Serological tests for HIV, syphilis, hepatitis C and B, CD4 counts, and viral load determination were performed. Cervical samples were collected for cytology and real-time PCR for HPV,Chlamydia, and Neisseria gonorrhoeae. RESULTS: In this study, 59% of women had at least one diagnosed STI at the time of the first clinic visit; 31% had clinical forms of anogenital HPV, 10% syphilis, 8%Neisseria gonorrhoeae, 5.0% trichomoniasis, 3% Chlamydia trachomatis, 1% hepatitis B, and 1% hepatitis C; 6.7% of the women presented with cervical cytological abnormalities. Furthermore, 46.3% of women had HR-HPV, and 17.6% had HPV 16/18. Only 5% of the women had a CD4 count <200 cells/mm3, 61.6% had undetectable HIV viral load, and 81.3% were currently on HAART. CONCLUSION: A high prevalence of STI and HR-HPV infections were observed among HIV-infected women in this investigation. Prevention programs need to focus on counseling WLHIV and their regular partners with focused interventions such as couples counseling and education programs.
