Analysis of combined prevention measures on HIV/AIDS incidence in Brazil (1980-2020) / Análise de medidas de prevenção combinadas sobre a incidência de HIV/AIDS no Brasil (1980­2020)

Introduction: The Human Immunodeficiency Virus (HIV) attacks the immune system, with acquired immunodeficiency syndrome (AIDS) being the most advanced clinical manifestation. Prevention strategies have evolved over time in response to scientific advancements. From an institutional perspective, the Unified Health System (SUS) provides tools for Combined Prevention to the entire Brazilian population, universally and free of charge. However, despite therapeutic advances, HIV/AIDS remains a significant public health problem. Objective: To analyze the impact of Combined Prevention measures on the incidence of HIV/AIDS in Brazil from 1980 to 2020. Methods: Quantitative, observational, longitudinal, and retrospective study. Descriptive and multivariate analyses were conducted, specifically employing linear regression techniques. The variables of interest included case incidence and the distribution of: tests for sexually transmitted infections (STIs), condoms, post-exposure prophylaxis for HIV (PEP), and pre-exposure prophylaxis for HIV (PrEP). Publicly available data were sourced from governmental repositories. Results: The country has accumulated 1,037,878 infection cases, with an average of 25,947 new cases per year. Regarding prophylaxis inputs, five out of six variables demonstrated a negative correlation with the incidence rate, with only the distribution of male condoms showing a positive correlation. The analysis of the effect of PrEP was not statistically significant. Conclusion:Brazil has reduced the incidence of the disease as Combined Prevention measures have advanced. More time is needed to assess the impact of PrEP on the incidence of new cases.

Introdução: O vírus da imunodeficiência humana (HIV) ataca o sistema imunológico. A síndrome da imunodeficiência adquirida (AIDS) é a manifestação clínica mais avançada. As estratégias de prevenção evoluíram ao longo do tempo conforme os avanços científicos. Do ponto de vista institucional, o Sistema Único de Saúde (SUS) disponibiliza ferramentas de prevenção combinada a toda a população brasileira de forma gratuita e universal. Contudo, apesar de todos os avanços terapêuticos, o HIV/AIDS continua sendo um grave problema de saúde pública. Objetivo: Analisar as medidas de prevenção combinada sobre a incidência de HIV/AIDS no Brasil no período entre 1980 e 2020. Métodos: Quantitativo, observacional, longitudinal e retrospectivo. Estatisticamente, foram realizadas análises descritiva e multivariada, mais especificamente a técnica de correção linear. As variáveis de interesse foram a incidência de caso e as distribuições de: testes para infecções sexualmente transmissíveis (IST), preservativos, profilaxia pós-exposição sexual ao HIV (PEP) e a profilaxia pré-exposição ao HIV (PrEP). Os dados utilizados são de caráter público e obtidos em repositórios governamentais. Resultados: O país acumula 1.037.878 casos de infecção, com média de 25.947 novos casos por ano. Quanto aos insumos de profilaxia, cinco das seis variáveis demonstraram correlação negativa com a taxa de incidência. Apenas a distribuição de preservativos masculinos teve correlação positiva. A análise do efeito da PrEP não foi estatisticamente significativa. Conclusão: O Brasil tem reduzido a incidência da doença à medida que avançam as medidas de prevenção combinada. É necessário mais tempo para analisar o impacto da PrEP na incidência de novos casos

Progress in research of strategies of expanding HIV testing in men who have sex with men / 中华流行病学杂志

In recent years, HIV infection prevalence in MSM has been in increase in China. HIV testing is the only way to identify HIV-infection, effectively curb the spread of HIV and reduce AIDS-related death risks. At present, the situation of HIV testing in MSM is not satisfactory, and expanding HIV testing is the one of the key measures for AIDS prevention and control in this population. This paper summarizes the role and strategies of expanding HIV testing in MSM in order to provide a reference for the improvement of HIV testing in this population.

Progress in research on HIV self-testing and associated factors among men who have sex with men in China / 中华流行病学杂志

HIV testing is the first step in HIV prevention and control, the rate of HIV infection is high and the rate of HIV testing is low among men who have sex with men (MSM) in China. HIV self-testing provides MSM with a new choice and plays a vital role in expanding the coverage of HIV testing in this population. This paper reviews HIV self-testing and associated factors among MSM in China and provides a reference for promoting HIV self-testing in this population.

Psychosocial characteristics pattern correlated with HIV-related risky sexual behavior among HIV-negative men who have sex with men: a latent profile analysis

BACKGROUND@#Men who have sex with men (MSM) have become a high risk population of HIV infection due to their risky sexual behaviors. The latent pattern of psychosocial characteristics plays an important effect in HIV-related risky behaviors among HIV-negative MSM.@*METHOD@#Participants were recruited from Wuhan, Nanchang, and Changsha city from September 2017 to January 2018. Social support was assessed by the multidimensional scale of social support, Connor-Davidson Resilience scale-10 items for reliance, the assessment of Stigma towards Homosexuality for sexual minority stigma, the Likert subscale of nondisclosure for identity concealment, the ACE questionnaire-Kaiser-CDC for adverse childhood experience, the Centers for Epidemiological Studies Depression Scale for depression. Latent profile analysis (LPA) and multivariate regression were used to analyze the data.@*RESULTS@#Three psychosocial characteristic patterns were revealed by the LPA. "Social support and resilience group" (SR group), "Identity concealment group" (IC group) and "Adverse childhood experience" (ACE group) were identified, respectively. In comparison with "SR group", "IC group" have a higher likelihood of one-night male partners (AOR = 2.74, 95%CI = [1.54, 4.90]), both fixed and one-night male partners (AOR = 2.01, 95%CI = [1.34, 3.01]) and HIV-unsure male partner (AOR = 2.12, 95%CI = [1.44, 3.13]). Similarly, "ACE group" were more likely having inconsistent condom use (AOR = 2.58, 95%CI = [1.41, 4.73]), and having sex with HIV-positive male partner (AOR = 4.90, 95%CI = [1.95, 12.30]) with comparison of "SR group". In addition, we further revealed that "ACE group" had a higher ratio (90.0%) of inconsistent condom use among MSM whose male partners were HIV-positive.@*CONCLUSIONS@#Six important psychosocial factors were divided into three latent pattern classes. Compared with "SR group", "IC group" and "ACE group" were more likely to engage in HIV-related risky sexual behaviors. Further research may pay more attention to "IC group" and "ACE group" for targeted intervention.

Progress on diagnosis and treatment of latent tuberculosis infection / 浙江大学学报·医学版

One fourth of the global population has been infected with Mycobacterium tuberculosis, and about 5%-10% of the infected individuals with latent tuberculosis infection (LTBI) will convert to active tuberculosis (ATB). Correct diagnosis and treatment of LTBI are important in ending the tuberculosis epidemic. Current methods for diagnosing LTBI, such as tuberculin skin test (TST) and interferon-γ release assay (IGRA), have limitations. Some novel biomarkers, such as transcriptome derived host genes in peripheral blood cells, will help to distinguish LTBI from ATB. More emphasis should be placed on surveillance in high-risk groups, including patients with HIV infection, those using biological agents, organ transplant recipients and those in close contact with ATB patients. For those with LTBI, treatment should be based on the risk of progression to ATB and the potential benefit. Prophylactic LTBI regimens include isoniazid monotherapy for 6 or 9 months, rifampicin monotherapy for 4 months, weekly rifapentine plus isoniazid for 3 months (3HP regimen) and daily rifampicin plus isoniazid for 3 months (3HR regimen). The success of the one month rifapentine plus isoniazid daily regimen (1HP regimen) suggests the feasibility of an ultra-short treatment strategy although its efficacy needs further assessment. Prophylactic treatment of LTBI in close contact with MDR-TB patients is another challenge, and the regimens include new anti-tuberculosis drugs such as bedaquiline, delamanid, fluoroquinolone and their combinations, which should be carefully evaluated. This article summarizes the current status of diagnosis and treatment of LTBI and its future development direction.

Impacto de la cuarentena por COVID-19 en el perfil metabólico de personas con infección por VIH en Argentina / Impact of COVID-19 related lockdown on the metabolic profile of people with HIV infection in Argentina

INTRODUCCIÓN: Para mitigar la propagación del SARS-CoV-2 se requirió de un confinamiento generalizado. Las autoridades argentinas impusieron aislamiento social preventivo durante 234 días (20 de marzo al 9 de noviembre de 2020), modificando el estilo de vida de la población. OBJETIVOS: Examinar la influencia de las medidas de bloqueo en el perfil metabólico de pacientes infectados por VIH en Argentina. PACIENTES Y MÉTODOS: Estudio de cohorte retrospectivo de 10.239 pacientes en seguimiento en una clínica de atención privada de personas con infección por VIH. Se incluyeron pacientes adultos con terapia antirretroviral (TARV) en curso que tuvieran una determinación de glucemia, colesterol total, colesterol HDL y trigliceridemia antes de la cuarentena (Pre-C: segundo semestre 2019) y una segunda determinación durante la misma (Intra-C: mayo 2020). Se excluyeron los pacientes con cambios en la TARV con impacto metabólico, los que iniciaron o suspendieron hipolipemiantes o hipoglucemiantes y mujeres embarazadas. Las variables categóricas se compararon mediante la prueba de la χ2 o la prueba exacta de Fisher y las continuas mediante la prueba t o la prueba de Mann-Whitney según correspondiera. Se consideró significativo un valor de p a dos colas < 0,05. RESULTADOS: Se incluyeron 540 individuos. La mediana de edad fue de 47 años y 74,6% fueron de sexo masculino. La mediana de índice de masa corporal fue 26,1 y 94,6% tenían bajo riesgo cardiovascular. Hubo un aumento significativo en el porcentaje de pacientes con hiperglucemia (Pre-C 5,2% vs Intra-C 8,5%, p 0,04), hipertrigliceridemia (Pre-C 33,9% vs Intra-C 40,7%, p 0,02) e hipercolesterolemia LDL (Pre-C 12,6% vs Intra-C 17,2%, p 0,04). CONCLUSIÓN: Nuestros resultados sugieren que la cuarentena, al menos en sus fases iniciales, puede tener un impacto negativo en el perfil metabólico de esta población.

BACKGROUND: The spread of SARS-CoV-2 required widespread lockdown to mitigate the pandemic. Argentine authorities imposed preventive social isolation for 234 days (March 20th to November 9th 2020). This measure led to major changes in the population's lifestyle. AIM: To examine the influence of COVID-19 lockdown measures on the metabolic profile of HIV-infected patients in Argentina. METHODS: Retrospective cohort study of 10,239 HIV-infected patients under follow up in a private clinic for HIV care. Adult patients with ongoing antiretroviral therapy (ART) and a baseline determination of blood glucose, total cholesterol, HDL-cholesterol and triglycerides done before lockdown (BL: second semester of 2019) and a second determination during lockdown (DL: May 2020) were included. Patients with recent changes in ART that may have metabolic impact, those starting lipid/glucose lowering agents and pregnant women were excluded. Categorical variables were compared using the χ2 test or Fisher's exact test, and continuous variables using the t-test or the Mann-Whitney test. A two-tailed value of p < 0.05 was considered significant. RESULTS: 540 individuals were included, median of age was 47 years and 74.6% were male. Median body mass index was 26.1 and 94.6% had low cardiovascular risk. There was a significant increase in the percentage of patients that met criteria for hyperglycemia (BL 4.8% and DL 8.5%, p < 0.001). We also observed significant (p < 0.001) increase in median (IQR) BL vs DL values in LDL-cholesterol [109 (90-128) vs 118 (97-139) mg/dL]; and triglycerides [120 (87-172) vs. 132 mg/dL (96-184)]. The proportion of patients with hyper-LDL cholesterolemia according to individual cardiovascular risk increased from 12.6 to 17.2% (p = 0.04). CONCLUSION: Our results suggest that quarantine, at least in its initial phases, may have a negative impact on the metabolic profile of this population.

La infección por vih en tiempos de pandemia: muchos retrocesos, innumerables desafíos / HIV infection in times of pandemic: many setbacks, countless challenges

Resumen Desde la llegada de la pandemia por COVID-19, se ha descrito un sinnúmero de consecuencias respecto a la infección por VIH en Chile, tanto en su diagnóstico como en su prevención, principalmente manifestadas en el descenso de la realización de exámenes serológicos, la interrupción de la atención, el retraso en el inicio de la terapia antirretroviral y la falta de acceso a métodos preventivos. A ello, se le suma el deterioro en algunas condiciones relacionadas con aspectos sociales y sobre salud mental. Todo esto implica, entre otras consecuencias, un probable empeoramiento en la situación epidemiológica de la infección por VIH en Chile. En el presente artículo, se revisarán algunos de los impactos señalados y se plantean algunos desafíos, para el enfrentamiento de esta problemática.

Abstract Since the arrival of the COVID-19 pandemic, countless consequences have been described regarding HIV infection in Chile, both in its diagnosis and prevention, mainly manifested in the decrease in serological tests, the interruption of care, the delay in starting antiretroviral therapy, and the lack of access to preventive methods. Added to this is the deterioration in some conditions related to social aspects and mental health. All this implies, among other consequences, a probable worsening in the epidemiological situation of HIV infection in Chile. Some of the designated impacts are reviewed in this article, and some challenges are raised to confront this problem.

Infección por SARS-CoV-2 en personas viviendo con VIH: tópicos del panorama mundial y en Chile / SARS-CoV-2 infection in people living with HIV: topics on the global panorama and in Chile

Resumen La enfermedad COVID-19 es una patología de origen infeccioso causada por el virus SARS-CoV-2 y fue declarada pandemia por la OMS el 11 de marzo 2020. A la fecha se registran más de 500 millones de personas infectadas y más de 6 millones de fallecidos en todo el mundo. Las personas que pertenecen a grupos de riesgo más vulnerables, particularmente aquellos que se encuentran en los extremos de la vida, con comorbilidades crónicas o inmunocomprometidas, son especialmente susceptibles a presentar un eventual mayor riesgo de infección, de gravedad y de mortalidad por esta enfermedad. Las personas que viven con VIH, especialmente aquellos en precarias condiciones inmunológicas o aquellas que aún no inician terapia antiretroviral, pueden ser un grupo especialmente susceptible de presentar complicaciones relacionadas a esta y otras enfermedades de origen infeccioso. Con esta revisión se pretende determinar la magnitud del impacto del virus SARS-CoV-2 en personas viviendo con VIH en Chile.

Abstract The COVID-19 disease is caused by the SARS-CoV-2 virus and was declared a pandemic by the WHO on March 11, 2020. To date, more than 500 million people have been infected and it has caused over 6 million deaths worldwide. People that belong to the most vulnerable risk groups, such as those at the extremes of life, patients with chronic comorbidities and those with severe immunosuppression, are especially susceptible to developing a severe form of COVID-19 infection and death. Subjects living with HIV, especially those in precarious immunological conditions or those in whom antiretroviral therapy is yet to be started, may be at risk of developing complications related to COVID-19, as observed with other infectious diseases. This review aims to determine the magnitude of the impact of the SARS-CoV-2 virus on people living with HIV in Chile.

Comportamiento sexual de pacientes con infección por VIH según grupos de edad / Sexual behavior among patients with HIV according to age groups

Nuestro objetivo fue determinar la prevalencia y conductas de riesgo por grupos de edad entre pacientes con infección por VIH. Se realizó un estudio observacional analítico transversal de pacientes que acuden al servicio de Enfermedades Infecciosas a recibir tratamiento antirretroviral. Resultados: De 117 personas que ingresaron al estudio, se observó que el grupo etario de los jóvenes varones con infección por VIH señalaron una orientación homosexual (HSH) en 64,5% y una mayor tasa de haber sufrido abuso sexual (29%) respecto al resto. En adultos el uso de métodos anticonceptivos es 71,4% y superior al resto de grupos de edad, la concurrencia a lugares de riesgo (visita a trabajadoras sexuales de la calle) se encuentra mayoritariamente en el rango de 45 a 90 años. El rol homosexual activo de los hombres con VIH representa 66,7%. Los hallazgos enfatizan la necesidad de realizar más estudios que profundicen el tema del abuso sexual en adolescentes y adultos jóvenes, debido a la alta prevalencia encontrada en este estudio(AU)

Our objective was to determine the prevalence and risk behaviors by age groups in patients with HIV infection. A cross-sectional analytical observational study of patients attending the Infectious Diseases service to receive antiretroviral treatment was carried out.Results: Out of 117 people who entered the study, it was observed that the age group of young men with HIV infection indicated a homosexual orientation (MSM) 64.5%; and a higher rate of having suffered sexual abuse (29%) in comparison to the others. In adults, the use of contraceptive methods is 71.4%, and higher than the rest of the age groups, attendance at places of risk (visits to street sex workers) is mostly in the range of 45 to 90 years. The active homosexual role of men with HIV represents 66.7%. The findings emphasize the need for more studies that delve into the issue of sexual abuse in adolescents and young adults, due to the high prevalence found in this study(AU)

Consideraciones en población transgénero respecto a la infección por VIH, terapia antiretroviral, profilaxis preexposición (PreP) e interacción con tratamiento de reafirmación de género / Considerations in the transgender population regarding HIV infection, antiretroviral therapy, pre-exposure prophylaxis (PreP) and interaction with gender reaffirmation treatment

Resumen La infección por VIH es una epidemia global (prevalencia de 0,8%). En Latinoamérica, Chile, Brasil y Uruguay son los países con mayores índices. Entre las más afectadas están la población transgénero (OR 48,8 respecto a la población general). Múltiples factores bio-psico-sociales explican estas cifras. Bajo uso del preservativo, la idea de reafirmación de género, el temor a ser reemplazadas(os) por personas cisgéneros, presencia de comercio sexual, entre otros, influyen en las mayores tasas de infección. Se han implementado medidas de prevención del VIH, pero pocas dirigidas en específico a personas transgénero. La profilaxis preexposición (PreP) parece ser una nueva alternativa de prevención en este grupo, y la integración de las unidades de apoyo en la reafirmación de género con las unidades que entregan PreP, podrían aumentar su adherencia y cobertura. En las personas transgénero con infección por VIH existe baja adherencia a terapia antirretroviral (TARV), en parte por priorización del tratamiento hormonal y miedo a que la TARV altere su proceso de hormonización. Los pocos datos existentes muestran que la hormonización no se afecta con la mayoría de la TARV, pero algunos tratamientos hormonales podrían disminuir las concentraciones plasmáticas y tisulares de ciertos antirretrovirales. Faltan estudios que evalúen la interacción entre antirretrovirales y tratamiento hormonal de reafirmación de género.

Abstract HIV infection is a global epidemic, with a prevalence of 0.8%. In Latin America, Chile, Brazil and Uruguay are the countries with the highest rates. The transgender population is the most affected (OR of 48.8 compared to the general population). Multiple bio-psycho-social factors explain these issues. The low use of condoms for pressure from the partner, the idea of reaffirmation of gender, the fear to be replaced by a cisgender person, the presence of commercial sex, among others, influence the highest rates of infection. HIV prevention measures have been implemented, but few specifically targeted at transgender people. Pre-exposure prophylaxis (PreP) seems to be a new prevention alternative in this group, and the integration of support units in gender reaffirmation with units that deliver PreP could increase their adherence and coverage. In HIV (+) transgender people there is low adherence to antiretroviral therapy (ART), in part due to the prioritization of hormonal treatment and the fear that ART will alter their hormonalization process. The few data that exist show that hormonalization is not affected by ART, but that some hormonal treatments could lower the levels of certain antiretrovirals. More studies must be done to evaluate the interaction between antiretrovirals and gender affirming hormone therapy.

Epidemiological data on HIV-infected patients and the importance of education regarding the infection rate. An analytical cross-sectional study

Abstract BACKGROUND: Sexually transmitted diseases (STIs) are an important public health problem in all countries. Knowledge of their relationship with the various socioeconomic levels is necessary for an understanding of their epidemiology and behavior in society. OBJECTIVE: To investigate the epidemiology of human immunodeficiency virus (HIV)-positive patients and to correlate education with history of sexually transmitted diseases, especially for syphilis. DESIGN AND SETTING: Analytical cross-sectional study carried out in the city of Juiz de Fora, Minas Gerais, Brazil. METHODS: The medical records of HIV/acquired immunodeficiency syndrome (AIDS) patients who started antiretroviral therapy (ART) between January 2010 and July 2018 were assessed. These patients were attended at the specialized assistance service for HIV/AIDS) of the Department of Sexually Transmitted Diseases (STD/AIDS) of the city of Juiz de Fora. In total, 335 patients were selected. RESULTS: In our sample, 73.13% were male; 57.36% were aged between 25 and 45 years and 24.23% were over 45 years of age. Regarding sexual orientation, 61.78% were homosexual. Regarding education, 52.88% had "unskilled education", while 47.12% had "qualified education". Analysis on the relationship between schooling and syphilis, a positive relationship between qualified schooling and syphilis was observed: odds ratio = 3.588; 95% confidence interval: 1.090-11.808. CONCLUSION: Homosexual male patients are most affected by HIV. Furthermore, this disease is not limited only to individuals with low education. Syphilis should be suspected in all individuals.

Abstract Objective To analyze the factors associated with death in people with HIV/AIDS. Method This is an epidemiological and analytical study, carried out from the HIV/AIDS notifications of the state of Mato Grosso do Sul, from 2009 to 2018. Data were analyzed using descriptive statistics, Kaplan-Meier survival analysis and Cox regression. Results A total of 8,712 notifications were analyzed, with a survival rate of 86% over the 10 years. Factors associated with death were: males (=1.22; p=0.006), brown skin color (=1.30; p=0.012), eight years or less of study (=1.57; p=0.000), and possible sexual transmission through intercourse with women (=2.72; p=0.000) or with both men and women (=2.24; p=0.002) and use of injectable drugs (=2.57; p=0.016). Conclusion Social, cultural and behavioral characteristics may contribute to reduce the survival of people with HIV/AIDS. These factors indicate specificities to be considered in care planning and monitoring of cases, especially with regard to the need for an active search, continuous monitoring, in addition to interventions that involve changes in behavior.

Panorama of risky sexual behaviors in the Brazilian adult population - PNS 2019 / Panorama dos comportamentos sexuais de risco na população adulta brasileira - PNS 2019

ABSTRACT OBJECTIVE To describe the risky sexual behaviors of Brazilian adults according to socioeconomic, demographic, and regional characteristics. METHODS Data from the 2019 National Health Survey, referring to the population aged 18 years or older, were analyzed. Risky sexual behaviors were considered: early sexual initiation, before the age of 15 years, and nonuse of condoms in the last sexual intercourse. Prevalence and respective confidence intervals were calculated for the subgroups of interest. RESULTS Early sexual initiation among adult individuals was 24% among men and 11% among women, being higher among young people with lower levels of education and household income. The nonuse of condoms was higher among married/cohabiting partners, no schooling or with some elementary school, and among older people. The prevalence of nonuse of condoms among married/cohabiting partners was the same in both sexes (75%). However, among non-cohabiting partners, gender disparity was relevant, as 39.1% of women did not use condoms in the last sexual intercourse, while among men this result was 26.9%. CONCLUSIONS Higher prevalence of early sexual initiation for younger generations is noteworthy, especially among women. Concerning the nonuse of condoms, there are important gender disparities in the group of non-cohabiting partners, in addition to the high prevalence among older people, which should be considered in the formulation of public policies. The results of the present study are extremely relevant for understanding the adult population currently more vulnerable to sexually transmitted infections, after over five years without official statistics on this matter at the national level.

RESUMO OBJETIVO Descrever os comportamentos sexuais de risco dos adultos brasileiros segundo características socioeconômicas, demográficas e regionais. MÉTODOS Foram analisados dados da Pesquisa Nacional de Saúde 2019, referente à população de 18 anos de idade ou mais. Considerou-se como comportamentos sexuais de risco: a iniciação sexual precoce, antes dos 15 anos, e o não uso de preservativo na última relação sexual. Foram calculadas as prevalências e respectivos intervalos de confiança para os subgrupos de interesse. RESULTADOS A iniciação sexual precoce entre indivíduos adultos foi de 24% entre os homens e 11% entre as mulheres, sendo mais alta entre jovens com menores níveis de instrução e rendimento domiciliar. O não uso de preservativo se mostrou maior entre os casados/coabitantes, sem instrução ou com nível fundamental incompleto, e entre os mais velhos. A prevalência do não uso de preservativo entre casados/coabitantes foi igual em ambos os sexos (75%). No entanto, entre os não coabitantes, a disparidade entre os sexos se mostrou relevante uma vez que 39,1% das mulheres não usaram preservativo na última relação sexual, enquanto entre os homens esse resultado foi de 26,9%. CONCLUSÃO Nota-se, especialmente entre as mulheres, maiores prevalências de iniciação sexual precoce para as gerações mais novas. No que se refere ao não uso de preservativo, há disparidades de sexo importantes no grupo dos não coabitantes, além da alta prevalência entre os mais velhos, que devem ser consideradas na elaboração das políticas públicas. Os resultados do presente estudo são extremamente relevantes para compreensão da população adulta atualmente mais vulnerável às infecções sexualmente transmissíveis, após mais de cinco anos sem estatísticas oficiais a respeito em âmbito nacional.

Descripción de situación epidemiológica del virus inmunodeficiencia humana en Chile durante los años 2016 a 2021 / Description of the epidemiological situation of human immunodeficiency virus in Chile during the years 2016 to 2021

Introducción: El virus de inmunodeficiencia humana (VIH) causa una infección que destruye los linfocitos del huésped. Su fase avanzada conlleva al Síndrome de Inmunodeficiencia Adquirida (SIDA) que trae consigo una alta morbimortalidad a nivel mundial, convirtiéndose en una pandemia de gran preocupación para las organizaciones mundiales de salud. Materiales y Métodos: Estudio de carácter observacional, descriptivo, ecológico y longitudinal retrospectivo. Se analizaron los datos del Departamento de Estadísticas de Información de Salud, número de casos confirmados, defunciones ocurridas en la población chilena, por región, entre los años 2016 y 2021 con causa básica de muerte Enfermedad por VIH [SIDA] y la cantidad total de exámenes realizados. Resultados: Se observa un aumento tanto en el número de exámenes realizados como de los casos diagnosticados hasta el año 2019. Respecto a la mortalidad se describe una tendencia decreciente desde el año 2016, con un alza puntual en 2019 tanto a nivel nacional como regional, por rango etario y sexo. A nivel regional se identifican mayores cifras en las macrozonas norte y centro. Discusión: En todas las regiones se evidenció una disminución durante los años 2020 y 2021, posiblemente asociada a un camuflaje en su categorización. La población chilena presenta una mayor tasa de mortalidad en el rango de 40 a 44 años, a diferencia del contexto mundial donde se observa un rango de 55 a 59 años. En causas específicas de mortalidad, se destaca el segundo lugar asociado a tumores malignos siendo importante destacar la necesidad de evidencia enfocada en el diagnóstico temprano de estas patologías.

Introduction: Human immunodeficiency virus (HIV) causes an infection that destroys host lymphocytes. Its advanced stage leads to Acquired Immunodeficiency Syndrome (AIDS) that brings with it a high morbimortality worldwide, becoming a pandemic of great concern for world health organizations. Materials and Methods: Observational, descriptive, ecological and retrospective longitudinal study. Data from the Department of Health Information Statistics, number of confirmed cases, deaths occurred in the Chilean population, by region, between the years 2016 and 2021 with basic cause of death HIV disease [AIDS] and the total number of tests performed were analyzed. Results: An increase is observed both in the number of examinations performed and cases diagnosed until 2019. Regarding mortality, a decreasing trend is described since 2016, with a punctual increase in 2019 both at national and regional level, by age range and sex. At the regional level, higher figures are identified in the northern and central macro-zones. Discussion: A decrease was evident in all regions during 2020 and 2021, possibly associated with a camouflage in their categorization. The Chilean population presents a higher mortality rate in the range of 40 to 44 years, unlike the world context where a range of 55 to 59 years is observed. In specific causes of mortality, the second place associated with malignant tumors stands out, being important to highlight the need for evidence focused on the early diagnosis of these pathologies.

Recent HIV infections: evaluation of a simple identification score for newly diagnosed patients

ABSTRACT OBJECTIVE Recognize incident infection to better characterize the groups that fuel HIV epidemic. We propose a simple score to identify recent infections among newly diagnosed patients as a HIV surveillance tool. METHODS Newly diagnosed patients were defined as recent infections when a negative serological test in the previous year was available. Laboratory tests, such as the avidity index (Bio-Rad, according to the CEPHIA protocol), chemiluminescent intensity (CMIA, architect, Abbott), and the nucleotide ambiguity index of partial pol sequences were used as proxies of recency. A simple score based on clinical symptoms of acute retroviral syndrome during the previous year, CD4+ T cell count, and viral load at admission was tested to assess the predictive power, using receiver operating characteristic (ROC) curves, to identify recent cases of infection. RESULTS We evaluated 204 recently diagnosed patients who were admitted to the Ambulatório de Referência em Moléstias Infecciosas de Santo André (Santo André Reference Infectious Diseases Outpatient Clinic), in the metropolitan region of São Paulo, Brazil, recruited between 2011 and 2018. An HIV-negative test in the year prior to enrollment was documented in 37% of participants. The proportion of cases classified as recent infections (less than one year), according to the laboratory proxies were: 37% (67/181) for an avidity index < 40%, 22% (30/137) for a CMIA < 200, and 68% (124/181) for an ambiguity index < 0.5%. Using different combinations of recency definitions, our score showed an area under the ROC curve from 0.66 to 0.87 to predict recency. CONCLUSIONS Using data from patients' interviews and routine laboratory tests at admission, a simple score may provide information on HIV recency and thus, a proxy for HIV incidence to guide public policies. This simple for the Brazilian public health system and other low- and middle-income countries.
