[Impure blood: specialists, institutions, and cultural authority in the context of AIDS in Brazil]. / Sangue impuro: especialistas, instituições e autoridade cultural no contexto da Aids no Brasil.

In this article, we examine the concept of cultural authority in the context of the professionalization/corporatization of medicine at the end of the 20th century, and its political and moral contours since the HIV/AIDS epidemic in São Paulo. Based on journalistic articles collected from the newspaper O Estado de São Paulo (1986-1989), we seek to highlight the place of medical expertise, examining the discourses produced about the disease in Brazil, in bases that show the emergence of social actors, disputes for credibility and the clinical authority under challenge. We analyze public narratives about AIDS, situating the place of authority. We argue that such discourses, in the context of sexual panic, did not occur outside a dynamic of therapeutic/clinical authority and the profession's own norms, which also immediately made visible the role of physicians, specialists and other health professionals, in dialogue with the moral grammar of the socially current illness. The conclusions illustrate the link between Brazilian medicine at the end of the century and the local-global history of AIDS, concentrating historical and political movements that disputed the scientific and moral meanings of the disease, fractured by the clash between authorities in the scientific, sanitary and clinical fields.

Neste artigo examinamos o conceito de autoridade cultural no contexto da profissionalização/corporativização da medicina no final do século XX e seus contornos políticos e morais desde a epidemia de HIV/Aids em São Paulo. A partir de matérias jornalísticas recolhidas do jornal O Estado de São Paulo (1986-1989), buscamos dar relevo ao lugar do especialismo médico, examinando os discursos produzidos sobre a doença, no Brasil, em bases que evidenciam a emergência de atores sociais, disputas por credibilidade e a autoridade clínica sob contestação. Analisamos as narrativas públicas sobre a Aids, situando o lugar da autoridade. Argumentamos que tais discursos, no contexto do pânico sexual, não ocorriam fora de uma dinâmica de autoridade terapêutica/clínica e das normatizações próprias da profissão, que também tornavam imediatamente visível o papel dos médicos, especialistas e demais profissionais de saúde, em diálogo com a gramática moral da doença socialmente corrente. As conclusões ilustram a vinculação da medicina brasileira de fins do século com a história local-global da Aids, concentrando movimentos históricos e políticos que disputavam os sentidos científicos e morais da doença, fraturados pelo embate entre autoridades no campo científico, sanitário e clínico.

Rates of adverse events of antiretroviral therapy in women living with HIV/AIDS: a systematic review and meta-analysis.

OBJECTIVE: There is limited information regarding the incidence of treatment-related adverse events (AE) following antiretroviral therapy (ART) in women. So, this review aimed to describe the incidence of AE of ART in women living with HIV/AIDS. DESIGN: Systematic review and meta-analysis. DATA SOURCES: Medline, Embase, Cochrane Library, Epistemonikos, Lilacs and Who Index, from inception to 9 April 2023. ELIGIBILITY CRITERIA: We included randomised controlled trials with at least 12 weeks of follow-up and evaluated AE of ART in women at any age living with HIV/AIDS, without restrictions on status, year or language of publication. We excluded post hoc or secondary analyses and open-label extensions without comparator, and trials involving pregnant or breastfeeding women or with a focus on coinfection with tuberculosis, hepatitis B or C. The primary outcomes were the incidence rate of participants with any clinical and/or laboratory AE related or not to ART and treatment discontinuation. DATA EXTRACTION AND SYNTHESIS: Two independent reviewers extracted data and assessed the risk of bias using Cochrane's risk of bias tool 2. We used Bayesian random-effects meta-analysis to summarise event rates. Results were presented as event rates per 1000 person-years (95% credibility intervals, 95% CrI). The pooled incidence rate per 1000 person-years adjusted for duration and loss to follow-up was estimated. We assessed the certainty of the evidence using Grading of Recommendations, Assessment, Development and Evaluation. RESULTS: A total of 24 339 studies were identified for screening, of which 10 studies (2871 women) met the eligibility criteria, with 11 different antiretrovirals (ARVs) regimens. Seven studies included exclusively women, while in the remaining three, the proportion of women ranged from 11% to 46%. Nine studies received industry funding. The pooled analysis showed a mean incidence rate of ART-related clinical and laboratory AE of 341.60 events per 1000 person-years (95% CrI 133.60-862.70), treatment discontinuation of 20.78 events per 1000 person-years (95% CrI 5.58-57.31) and ART-related discontinuation of 4.31 per 1000 person-years (95% CrI 0.13-54.72). Summary estimates were subject to significant uncertainty due to the limited number of studies and sparse data. The certainty of the evidence was graded as very low for all outcomes assessed. CONCLUSION: Existing randomised trials do not provide sufficient evidence on the incidence rates of safety outcomes from antiretroviral treatment in women living with HIV/AIDS. Large comparative studies in well-characterised populations are needed to provide a more comprehensive landscape of the safety profile of these ARV therapies in women with HIV/AIDS.

Epidemias de significação e políticas de saúde global: Do fim da AIDS ao fim da ampliação da resposta global da AIDS.

RESUMONas últimas quatro décadas e meia, a história da pandemia de HIV passou por várias fases que podem ser pensadas como ondas distintas em termos da resposta social e política que a pandemia gerou. Ao longo dessa história, houve batalhas importantes sobre os significados e interpretações que a resposta à pandemia produziu. Mas, especialmente na última década, parece haver uma crescente desconexão entre as alegações de sucesso feitas por muitas agências globais de saúde e formuladores de políticas e a realidade empírica que essas alegações encobrem. Este comentário argumenta que a 'ampliação' ('scale-up') da resposta à pandemia essencialmente chegou ao fim e enfatiza a importância de um debate político mais honesto sobre o estado atual da resposta global ao HIV. Argumenta que, a fim de melhor definir os rumos que tal resposta deve tomar no futuro, exige que pensemos criticamente sobre as formas como essa resposta se desenvolveu historicamente, que reconheçamos os avanços significativos alcançados nas últimas décadas, mas também que reconheçamos a encruzilhada a que chegou em meados da década de 2020.

The impact of primary health care on AIDS incidence and mortality: A cohort study of 3.4 million Brazilians.

BACKGROUND: Primary Health Care (PHC) is essential for effective, efficient, and more equitable health systems for all people, including those living with HIV/AIDS. This study evaluated the impact of the exposure to one of the largest community-based PHC programs in the world, the Brazilian Family Health Strategy (FHS), on AIDS incidence and mortality. METHODS AND FINDINGS: A retrospective cohort study carried out in Brazil from January 1, 2007 to December 31, 2015. We conducted an impact evaluation using a cohort of 3,435,068 ≥13 years low-income individuals who were members of the 100 Million Brazilians Cohort, linked to AIDS diagnoses and deaths registries. We evaluated the impact of FHS on AIDS incidence and mortality and compared outcomes between residents of municipalities with low or no FHS coverage (unexposed) with those in municipalities with 100% FHS coverage (exposed). We used multivariable Poisson regressions adjusted for all relevant municipal and individual-level demographic, socioeconomic, and contextual variables, and weighted with inverse probability of treatment weighting (IPTW). We also estimated the FHS impact by sex and age and performed a wide range of sensitivity and triangulation analyses; 100% FHS coverage was associated with lower AIDS incidence (rate ratio [RR]: 0.76, 95% CI: 0.68 to 0.84) and mortality (RR: 0.68, 95%CI: 0.56 to 0.82). FHS impact was similar between men and women, but was larger in people aged ≥35 years old both for incidence (RR: 0.62, 95% CI: 0.53 to 0.72) and mortality (RR: 0.56, 95% CI: 0.43 to 0.72). The absence of important confounding variables (e.g., sexual behavior) is a key limitation of this study. CONCLUSIONS: AIDS should be an avoidable outcome for most people living with HIV today and our study shows that FHS coverage could significantly reduce AIDS incidence and mortality among low-income populations in Brazil. Universal access to comprehensive healthcare through community-based PHC programs should be promoted to achieve the Sustainable Development Goals of ending AIDS by 2030.

The challenges of Chile to achieve control the HIV/AIDS pandemic the year 2030: A review.

Chile is contending with the highest rates of new human immunodeficiency virus (HIV) cases in both Latin America and globally, despite substantial ongoing investments in treatment. This comprehensive study, derived from PUBMED and Google searches, ANID data, and various organizational reports, highlights key areas for improvement. Over the past decade, Chile's annual infection rate has risen, signaling an urgent need for detailed analysis and effective solutions. The study includes 44 references, comprising 32 scientific articles and 12 reports from entities like the WHO and the Pan American Health Organization. Data was meticulously collected through diverse means, such as scientific congresses, meetings with authorities, and direct data requests. Fourteen critical points are identified for addressing the HIV epidemic in Chile, spanning from legislative reforms to enhanced prevention campaigns. Key recommendations include universal diagnosis, decentralized healthcare, the availability of self-tests, and a focus on mental health and the impact of migration. Despite Chile's strong economic indicators, factors such as inadequate sexual education, outdated legislation, and centralized diagnostic processes contribute to the persistent increase in new cases. The study underscores the pressing need for enhanced investment in prevention policies. Chile faces significant challenges in meeting the 90/90/90 targets, yet there is optimism in aiming for the 95/95/95 strategy by 2030. Achieving success requires a global commitment, an emphasis on prevention, and collaborative efforts among authorities, healthcare providers, and patients. Overcoming these identified barriers is essential for Chile to reach its ambitious goal and ultimately end the HIV epidemic.

Evaluating social protection mitigation effects on HIV/AIDS and Tuberculosis through a mathematical modelling study.

The global economic downturn due to the COVID-19 pandemic, war in Ukraine, and worldwide inflation surge may have a profound impact on poverty-related infectious diseases, especially in low-and middle-income countries (LMICs). In this work, we developed mathematical models for HIV/AIDS and Tuberculosis (TB) in Brazil, one of the largest and most unequal LMICs, incorporating poverty rates and temporal dynamics to evaluate and forecast the impact of the increase in poverty due to the economic crisis, and estimate the mitigation effects of alternative poverty-reduction policies on the incidence and mortality from AIDS and TB up to 2030. Three main intervention scenarios were simulated-an economic crisis followed by the implementation of social protection policies with none, moderate, or strong coverage-evaluating the incidence and mortality from AIDS and TB. Without social protection policies to mitigate the impact of the economic crisis, the burden of HIV/AIDS and TB would be significantly larger over the next decade, being responsible in 2030 for an incidence 13% (95% CI 4-31%) and mortality 21% (95% CI 12-34%) higher for HIV/AIDS, and an incidence 16% (95% CI 10-25%) and mortality 22% (95% CI 15-31%) higher for TB, if compared with a scenario of moderate social protection. These differences would be significantly larger if compared with a scenario of strong social protection, resulting in more than 230,000 cases and 34,000 deaths from AIDS and TB averted over the next decade in Brazil. Using a comprehensive approach, that integrated economic forecasting with mathematical and epidemiological models, we were able to show the importance of implementing robust social protection policies to avert a significant increase in incidence and mortality from AIDS and TB during the current global economic downturn.

HIV and AIDS in the state of Paraná, Brazil, 2007-2022: trends and spatiotemporal distribution.

OBJECTIVE: The aim of this study was to analyze the spatiotemporal evolution of the incidence rates of human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) in the state of Paraná, Brazil. METHODS: An ecological study with an analytical component of time series analysis was conducted in the state of Paraná from 2007 to 2022. The data source was the Notifiable Diseases Information System. To study the trend, the Prais-Winsten generalized linear regression model was used by decomposing the time series, and for spatial analysis, the Moran's index was applied. RESULTS: The total sample consisted of 50,676 HIV/AIDS records. The incidence rate showed an increasing trend, with an average growth of 2.14% [95% confidence interval - 95%CI 1.16-3.13] per month. From 2007 to 2014 and from 2015 to 2022, the average number of cases in the state was 105.64 and 159.20 per 100,000 inhabitants, respectively, with significant variation among municipalities. Spatial clusters of high risk persisted in the metropolitan region, the capital, and coastal areas, and a new cluster was observed in the northern region of the state. CONCLUSION: The incidence rates of HIV/AIDS showed an upward trend over time. The number of cases varied considerably in some municipalities, especially in the coastal region. Spatial analysis revealed geospatial patterns of high risk in the main metropolitan areas of Paraná: Curitiba (including the coastal area), Londrina, and Maringá, which share characteristics such as a high degree of urbanization and ongoing economic development.

Epidemiological profile of individuals with HIV/Aids in a municipality in Maranhão State, Brazil, from 2017 to 2020 / Perfil epidemiológico de individuos con VIH/SIDA en municipio en Maranhão, Brasil, de 2017 a 2020 / Perfil epidemiológico de indivíduos com HIV/Aids em município no Maranhão, Brasil, de 2017 a 2020

Background and Objective: To understand the main forms of transmission of HIV in order to foster the containment of the transmission chain, early diagnosis and the epidemiological profile of patients. In this sense, it will enable the analysis of the epidemiological profile and the transmissibility variables of patients with HIV/Aids from the municipality of Imperatriz-MA.. Method: This is an observational cross-sectional study. Data collection was performed from the analysis of patients' records registered in the Center for Testing and Counseling (CTA) from 2017 to 2020. For data collection, a questionnaire with transmission variables and epidemiological characteristics of patients was used. Results: From January 2017 to December 2020, 211 medical records were filed. Of these, 71.6% were male, 55.5% of the participants were between 21 and 40 years, and 66.4% from Imperatriz-MA. The most prevalent type of exposure was sexual intercourse without a condom. Among the participants, 83.9% (n=177) were positive only for HIV. About 140 people with HIV had an undetectable viral load (VL) (< 50 copies/ml) after 6 months of using antiretroviral therapy, making it low transmissibility. Conclusion: The study was able to characterize the epidemiological profile of patients from the Specialized Assistance Service (SAE) in Imperatriz between 2017 and 2020. Despite the increase in the number of cases among women, the most affected public remains young men, from 21 to 40 years of age, with 8 to 11 years of education, single and brown. Sexual intercourse without a condom is the main type of exposure.(AU)

Modelling HIV/AIDS epidemiological complexity: A scoping review of Agent-Based Models and their application.

OBJECTIVE: To end the AIDS epidemic by 2030, despite the increasing poverty and inequalities, policies should be designed to deal with population heterogeneity and environmental changes. Bottom-up designs, such as the Agent-Based Model (ABM), can model these features, dealing with such complexity. HIV/AIDS has a complex dynamic of structural factors, risk behaviors, biomedical characteristics and interventions. All embedded in unequal, stigmatized and heterogeneous social structure. To understand how ABMs can model this complexity, we performed a scoping review of HIV applications, highlighting their potentialities. METHODS: We searched on PubMed, Web of Science, and Scopus repositories following the PRISMA extension for scoping reviews. Our inclusion criteria were HIV/AIDS studies with an ABM application. We identified the main articles using a local co-citation analysis and categorized the overall literature aims, (sub)populations, regions, and if the papers declared the use of ODD protocol and limitations. RESULTS: We found 154 articles. We identified eleven main papers, and discussed them using the overall category results. Most studies model Transmission Dynamics (37/154), about Men who have sex with Men (MSM) (41/154), or individuals living in the US or South Africa (84/154). Recent studies applied ABM to model PrEP interventions (17/154) and Racial Disparities (12/154). Only six papers declared the use of ODD Protocol (6/154), and 34/154 didn't mention the study limitations. CONCLUSIONS: While ABM is among the most sophisticated techniques available to model HIV/AIDS complexity. Their applications are still restricted to some realities. However, researchers are challenged to think about social structure due model characteristics, the inclusion of these features is still restricted to case-specific. Data and computational power availability can enhance this feature providing insightful results.

Income determines the impact of cash transfers on HIV/AIDS: cohort study of 22.7 million Brazilians.

Living with extremely low-income is an important risk factor for HIV/AIDS and can be mitigated by conditional cash transfers. Using a cohort of 22.7 million low-income individuals during 9 years, we evaluated the effects of the world's largest conditional cash transfer, the Programa Bolsa Família, on HIV/AIDS-related outcomes. Exposure to Programa Bolsa Família was associated with reduced AIDS incidence by 41% (RR:0.59; 95%CI:0.57-0.61), mortality by 39% (RR:0.61; 95%CI:0.57-0.64), and case fatality rates by 25% (RR:0.75; 95%CI:0.66-0.85) in the cohort, and Programa Bolsa Família effects were considerably stronger among individuals of extremely low-income [reduction of 55% for incidence (RR:0.45, 95% CI:0.42-0.47), 54% mortality (RR:0.46, 95% CI:0.42-0.49), and 37% case-fatality (RR:0.63, 95% CI:0.51 -0.76)], decreasing gradually until having no effect in individuals with higher incomes. Similar effects were observed on HIV notification. Programa Bolsa Família impact was also stronger among women and adolescents. Several sensitivity and triangulation analyses demonstrated the robustness of the results. Conditional cash transfers can significantly reduce AIDS morbidity and mortality in extremely vulnerable populations and should be considered an essential intervention to achieve AIDS-related sustainable development goals by 2030.

Boletim epidemiológico: situação epidemiológica do HIV/Aids no Estado de Goiás, 2018 a 2023 / Epidemiological bulletin: epidemiological situation of HIV/AIDS in the State of Goiás, 2018 to 2023

A síndrome da imunodeficiência adquirida (SIDA) denomina o conjunto de sintomas e infecções resultantes dos danos causados ao sistema imunológico pelo vírus da imunodeficiência humana (HIV). Nesse boletim é demonstrado a epidemiologia da infecção por HIV/Aids na população residente em Goiás conforme ano de notificação e diagnóstico laboratorial com uma análise descritiva dos dados obtidos do Sistema de Informação de Agravos de Notificação - SINAN, Sistema de Informação de Mortalidade - SIM, e Sistema de Informação de Nascidos Vivos - SINASC, no período de janeiro de 2018 a novembro de 2023,diagnosticados e notificados por município de residência pelos serviços de saúde do Estado de Goiás

Acquired immunodeficiency syndrome (AIDS) refers to the set of symptoms and infections resulting from damage caused to the immune system by the human immunodeficiency virus (HIV). This bulletin demonstrates the epidemiology of HIV/AIDS infection in the population residing in Goiás according to year of notification and laboratory diagnosis with a descriptive analysis of data obtained from the Notifiable Diseases Information System - SINAN, Mortality Information System - SIM, and Live Birth Information System - SINASC, from January 2018 to November 2023, diagnosed and notified by municipality of residence by the health services of the State of Goiás

Reduced HIV/AIDS diagnosis rates and increased AIDS mortality due to late diagnosis in Brazil during the COVID-19 pandemic.

The COVID-19 pandemic has severely affected global health, leading to the suspension of numerous routine healthcare services and posing challenges in efforts to control other diseases, such as HIV/AIDS. This study aimed to assess the impact of the COVID-19 pandemic on HIV/AIDS diagnoses and mortality rates in Brazil during 2020 and 2021. The percentage change was calculated to determine whether there was an increase or decrease in HIV/AIDS diagnoses and mortality, considering the average numbers from the last 5 years. Additionally, a Joinpoint regression model and an interrupted time series analysis were applied to assess time trends before and after the onset of the pandemic. Lastly, choropleth maps were prepared. We observed a reduction of 22.4% (2020) and 9.8% (2021) in the diagnosis of HIV/AIDS in Brazil. Conversely, there was a significant increase in the percentage change of late diagnosis of AIDS deaths in 2020 (6.9%) and 2021 (13.9%), with some states showing an increase of over 87%. Decreasing time trends in the diagnosis of HIV/AIDS were identified before the pandemic in Brazil, especially in the Southeast and South regions, and then time trends stabilized after including the pandemic years. Along with the dissemination of COVID-19, there was a reduction in the diagnosis of HIV/AIDS and an increase in late diagnosis AIDS deaths, signaling a serious impact of the pandemic on HIV/AIDS control strategies in Brazil. Therefore, we highlight the need for continuous efforts to control both diseases, that is, maintaining regular health services even in crisis situations.

Ethics in infectious diseases: latent challenges. Part I.

Infectious diseases socially imply individual and community medical problems. Therefore, they require actions aimed at social processes that affect the well-being of the individuals without losing sight of social groups. Faced with this panorama, we ask ourselves: is there a direct relationship between ethics and infectious diseases? To elucidate an answer, let us remember the peak period of the COVID-19 pandemic when guidelines based on ethical principles were issued to facilitate medical decisions on allocating scarce resources in periods of maximum demand. In those moments, since there was no inclusive component of society, the decisions made produced massive criticism. The reactions demonstrated the need to analyze in detail the criteria that had been considered correct. Consequently, we affirm that bioethical principles are transcendental in medical decisions and must be examined, not only for the individual but also with a view to public health. Moreover, the acquired immunodeficiency syndrome (AIDS) epidemic has lived with us for decades, and it continues to show its tragic face in the form of new cases, chronic illnesses, and deaths. Joint United Nations Programme on HIV/AIDS brings us closer to a complex reality where the fight against disease and global health are interrelated with other problems, such as the need to reduce inequality, for which human rights, gender equality, social protection, and the development of research projects, where the ethics committees in research in community processes are constituents.

Las enfermedades infecciosas implican problemas médicos individuales y comunitarios, por lo que requieren acciones dirigidas a procesos sociales que incidan en el bienestar de los individuos, sin perder de vista a los grupos sociales. Nos preguntamos: ¿existe relación directa entre la ética y las enfermedades infecciosas? Para dilucidar una respuesta, recordemos el periodo más álgido de la pandemia por COVID-19, cuando se emitieron guías fundamentadas en principios éticos para facilitar las decisiones médicas en la asignación de recursos escasos en periodos de máxima demanda. Al no haber un componente inclusivo con la sociedad, las decisiones que se tomaron produjeron críticas masivas, que demostraron la necesidad de analizar a detalle los criterios que se habían considerado correctos. En consecuencia, afirmamos que los principios bioéticos son trascendentales en las decisiones médicas y deben ser examinados, no solo frente al individuo, sino de cara a la salud pública (bien común e individualidad). Por otra parte, la epidemia del SIDA (síndrome de inmunodeficiencia adquirida) convive con nosotros desde hace décadas. ONUSIDA (Programa Conjunto de las Naciones Unidas sobre el VIH/SIDA) nos acerca una realidad compleja, como es que la lucha contra la enfermedad y por la salud global se interrelaciona con otros problemas como la necesidad de reducer la desigualdad, por los derechos humanos, la igualdad de género, la protección social y el desarrollo de proyectos de investigación, donde los comités de Ética en investigación en procesos comunitarios son constituyentes.

Introduction: HIV/AIDs is a public health problem with worldwide epidemiological changes. Objective: To analyze the trend in AIDS incidence coefficients and possible points of change in adults aged 20 to 59 in Brazil, by region, from 2010 to 2017. Method: Ecological study of time and local series, with data referring to the years 2010 to 2017, collected in the Information Technology Department of the Unified Health System, on the diseases referred to, and population data on the website of the Brazilian Institute of Geography and Statistics. The cases were divided by regions of Brazil, in addition to sex and age group. To analyze changes in annual incidences by sex and age group, a Joinpoint regression model was used. Results: AIDS showed an increasing trend among male individuals aged 20 to 29 years in the Central-West, Northeast and North regions and remained, for the most part, stationary in the other age groups in both sexes. Conclusion: There is a need to strengthen the Primary Health Care team and its role in preventing AIDS, as well as expanding specialized services in other regions, in addition to the Southeast and South. Prevention actions aimed at the male public must be stimulated, and also discussed in a school environment, on an ongoing basis, with young people

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

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

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

A Bayesian approach for mixed effects state-space models under skewness and heavy tails.

Human immunodeficiency virus (HIV) dynamics have been the focus of epidemiological and biostatistical research during the past decades to understand the progression of acquired immunodeficiency syndrome (AIDS) in the population. Although there are several approaches for modeling HIV dynamics, one of the most popular is based on Gaussian mixed-effects models because of its simplicity from the implementation and interpretation viewpoints. However, in some situations, Gaussian mixed-effects models cannot (a) capture serial correlation existing in longitudinal data, (b) deal with missing observations properly, and (c) accommodate skewness and heavy tails frequently presented in patients' profiles. For those cases, mixed-effects state-space models (MESSM) become a powerful tool for modeling correlated observations, including HIV dynamics, because of their flexibility in modeling the unobserved states and the observations in a simple way. Consequently, our proposal considers an MESSM where the observations' error distribution is a skew-t. This new approach is more flexible and can accommodate data sets exhibiting skewness and heavy tails. Under the Bayesian paradigm, an efficient Markov chain Monte Carlo algorithm is implemented. To evaluate the properties of the proposed models, we carried out some exciting simulation studies, including missing data in the generated data sets. Finally, we illustrate our approach with an application in the AIDS Clinical Trial Group Study 315 (ACTG-315) clinical trial data set.

Factors Associated with Late Diagnosis of Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) in a University Hospital in Brazil: Challenges to Achieving the 2030 Target.

INTRODUCTION: This study aimed to identify factors associated with late diagnosis and clinically monitor newly diagnosed HIV/AIDS patients. METHOD: Retrospective study, based on secondary data from a specialized unit at the Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto of the University of Sao Paulo. Data collection included sociodemographic, behavioral, clinical, and laboratory data of newly diagnosed HIV patients between 2015 and 2019. Data analysis was undertaken using inferential statistical tests. RESULTS: A total of 314 individuals were newly diagnosed with HIV/AIDS, 86.6% (272) had a late diagnosis and 53.8% (169) were diagnosed very late. Using the adjusted odds ratio, we observed that bisexual and MSM patients were less likely to have a late diagnosis compared to straight patients. Individuals who entered through the emergency department and Outpatient Clinic had a lower chance of having a very late diagnosis compared to those diagnosed in the ward/inpatient unit. Having a higher education and university education were protective factors against having a very late diagnosis of HIV infection compared to elementary school education only. In addition, male patients were more likely to have a very late diagnosis compared to female patients. CONCLUSIONS: This study evidenced a high prevalence of late and very late diagnoses. Therefore, attention should be directed towards factors related to late and very late presentation.

Prevalencia y caracterización de las neoplasias malignas en personas viviendo con VIH en Colombia / Prevalence and characterization of cancer in people living with HIV in Colombia

INTRODUCCIÓN: En el síndrome de inmunodeficiencia adquirida las neoplasias han jugado un papel preponderante, y con el advenimiento del tratamiento antirretroviral (TAR), la infección por VIH se ha transformado en una enfermedad crónica, siendo los tumores malignos una causa importante de morbilidad y mortalidad. OBJETIVO: Describir las características demográficas, clínicas y de laboratorio de las personas que viven con VIH (PVVIH) y han sido diagnosticadas con cáncer en Colombia y comparar los grupos de neoplasias definitorias y no definitorias de Sida. MÉTODOS: Revisión multicéntrica retrospectiva, en la que se recolectó y analizó datos relacionados con la infección por VIH y de diagnóstico de cáncer y tipo. Incluyó PVVIH diagnosticadas con neoplasias malignas atendidas en 23 centros de atención de pacientes con VIH en 11 ciudades de Colombia desde 1986 hasta 2018. RESULTADOS: En 23.189 pacientes, se identificaron 650 casos de malignidad (prevalencia de 2,8 % [IC de 95%: 2,6-2,9]). La neoplasia definitoria de Sida (NDS) sigue siendo el tipo de cáncer prevalente (71,1%), las neoplasias malignas más frecuentes fueron sarcoma de Kaposi (n: 330; 50,8%), linfoma no Hodgkin (n: 110; 16,9%), cáncer de piel (n: 48; 7,4%) y linfoma de Hodgkin (n: 25; 3,8%). Los pacientes con NDS tenían más probabilidades de ser HSH y estar en un estadio CDC 3, un recuento de linfocitos T CD4 < 200/μL y una carga viral del VIH ≥ 50 copias/mL al momento del diagnóstico de malignidad. Las personas con neoplasias no definitorias de Sida (NNDS) eran significativamente mayores y tenían más probabilidades de ser fumadores. CONCLUSIONES: Estos hallazgos son relevantes considerando la creciente carga de cáncer en las PVVIH que envejecen y las causas cambiantes de morbilidad y mortalidad. La presentación tardía a la atención del VIH y el retraso en el inicio del TAR son probablemente factores que contribuyen al cambio más lento hacia NNDS en comparación con las regiones de altos ingresos donde hay un acceso más rápido y temprano al TAR. El conocimiento de las tendencias epidemiológicas actuales y el perfil del cáncer en las PVVIH es fundamental para mejorar los esfuerzos de prevención y tratamiento del cáncer en el contexto de la atención integral del VIH.

BACKGROUND: In the acquired immunodeficiency syndrome, neoplasms have played a preponderant role, and with the advent of antiretroviral treatment (ART), HIV has become a chronic disease, with malignant tumors being an important cause of morbidity and mortality. AIM: To describe the demographic, clinical, and laboratory characteristics of people living with HIV (PLHIV) who have been diagnosed with cancer in Colombia and to compare the groups of AIDS-defining (ADC) and non-AIDS-defining neoplasms (NADC). METHODS: Retrospective, multicenter study that included people living with HIV/AIDS (PLHIV) diagnosed with malignancies treated at 23 HIV care centers located in 11 Colombian cities from 1986 to 2018. Data related to HIV infection and cancer diagnosis were collected and analyzed. RESULTS: Among 23,189 patients, 650 malignancy cases were identified (prevalence of 2.8% [95% CI 2.6-2.9]). AIDS-defining neoplasm remains the most prevalent type of cancer (71.1%), The most frequent individual malignancies were Kaposi sarcoma (n: 330; 50.8%), non-Hodgkin lymphoma (n: 110; 16.9%), skin cancer (n: 48; 7.4%), and Hodgkin lymphoma (n: 25; 3.8%). Compared people with NADC, with ADC were more likely to be MSM and have a CDC HIV stage 3, CD4 T cell count < 200/μL, and HIV viral load ≥ 50 copies/mL at the time of malignancy diagnosis. PLHIV and with NADC were significantly older and were more likely to be smokers. CONCLUSIONS: These findings are relevant considering the increasing burden of cancer in the aging PLHIV and the changing causes of morbidity and mortality. Late presentation to HIV care and delayed ART initiation are likely factors contributing to the slower shift toward NADCs compared with high-income regions where access to ART is better. Knowledge of the current epidemiological trends and profile of cancer in PLWHA is critical to improve cancer prevention and treatment efforts in the context of comprehensive HIV care.
