BACKGROUND According to the last 2023 Monkeypox (Mpox) Outbreak Global Map from the Centres for Disease Control and Prevention (CDC), more than 100 countries with no Mpox infection report cases. Brazil stands out in this group and is the second country with the highest number of cases in the last outbreak. OBJECTIVE To contribute to knowledge of the virus infection effects in a cellular model, which is important for diagnosis infections not yet included in a provider´s differential diagnosis and for developing viral inhibition strategies. METHODS We describe a virus isolation protocol for a human clinical sample from a patient from Brazil, the viral growth in a cell model through plaque forming units (PFU) assay, reverse transcriptase polymerase chain reaction (RT-PCR) and transmission electron microscopy (TEM). FINDINGS We follow the viral isolation in Vero cell culture from a Mpox positive clinically diagnosed sample and show the infection effects on cellular structures using a TEM. MAIN CONCLUSIONS Understanding the impact of viral growth on cellular structures and its replication kinetics may offer better strategies for the development of new drugs with antiviral properties.

Resumo: Os autores avaliaram as proporções de subnotificação de óbitos e fatores associados em pessoas vivendo com HIV (PVHIV) no Rio de Janeiro, Brasil, entre 2014 e 2019. Variáveis demográficas, menção de tuberculose (TB) e contagem de células CD4 mais próxima ao óbito foram utilizadas para comparar indivíduos que tiveram códigos para HIV/aids mencionados na declaração de óbito (HMDO) àqueles que não apresentaram tal menção. Entre 10.698 certidões de óbito, 2.863 (26.8%) não citaram HIV/aids. Entre estes, 412 (14,4%) apresentaram causas externas como a causa subjacente. Depois de excluir as causas externas, 24% das certidões não mencionaram HIV/aids. Idade acima de 40 anos (OR = 1,75; IC95%: 1,52-2,01), raça/etnicidade não branca (OR = 1,16; IC95%: 1,02-1,31), sexo masculino (OR = 1,25; IC95%: 1,11-1,42), contagem de CD4 mais alta próximo ao óbito (OR = 1,14; IC95%: 1,12-1,16), não ter TB (OR = 4,86; IC95%: 3,76-6,29) e morte extra-hospitalar (OR = 2,61; IC95%: 2,31-2,95) mostraram associação com aumento de probabilidade de não apresentar HMDO. A proporção de certidões de óbito que não citavam HIV/aids aumentou de 18,7% para 35,1% entre 2014 e 2019. A alta proporção de óbitos subnotificados no Rio de Janeiro indica a possível subestimação dos coeficientes de mortalidade por HIV/aids no estado. A mudança nos padrões de mortalidade em PVHIV desafia tanto os médicos, no sentido de considerar o espectro clínico mais amplo na infecção pelo HIV, quanto os especialistas em vigilância, no sentido de aprimorar o monitoramento da mortalidade.

Abstract: We assessed the proportions and causes of the underreporting of deaths among people living with HIV (PLHIV) in Rio de Janeiro, Brazil, from 2014 to 2019. Demographic variables, mention of tuberculosis (TB), and CD4 cell counts closest to death were used to compare those who had HIV/AIDS mentioned on their death certificate (HMDC) to those who did not. Out of 10,698 deaths, 2,863 (26.8%) had no HMDC, from which 412 (14.4%) had external underlying cause. After excluding deaths from external causes, we found that 24% still had no HMDC. Age ≥ 40 years (OR = 1.75; 95%CI: 1.52-2.01), non-white race/ethnicity (OR = 1.16; 95%CI: 1.02-1.31), the male gender (OR = 1.25; 95%CI: 1.11-1.42), higher CD4 cell counts closest to death (OR = 1.14; 95%CI: 1.12-1.16), absence of TB (OR = 4.86; 95%CI: 3.76-6.29) and not dying within a hospital (OR = 2.61; 95%CI: 2.31-2.95) were associated with increased probabilities of not having HMDC. The proportion of deaths with no HMDC increased from 18.7% to 35.1% between 2014 and 2019. The high proportion of underreported deaths in Rio de Janeiro indicates that HIV/AIDS mortality coefficients in the state may be underestimated. With the changing patterns of mortality of PLHIV, physicians are advised to consider the broader clinical spectrum of HIV infection, and surveillance officers should improve death monitoring.

Resumen: Evaluamos los porcentajes y factores asociados con el subregistro de muertes entre personas afectadas por VIH (PLHIV) en Río de Janeiro, Brasil, desde 2014 a 2019. Se utilizaron variables demográficas, mención de tuberculosis (TB) y recuentos de células CD4 más cercanos al fallecimiento, para comparar a quienes tenían VIH/SIDA reflejado en el certificado de defunción (HMDC), con quienes no lo tenían. De las 10.698 muertes, 2.863 (26,8%) no tuvieron HMDC. De entre ellos, 412 (14,4%) tenían causas externas como causa subyacente. Tras excluir las causas externas, un 24% no tuvieron HMDC. Edad ≥ 40 años (OR = 1,75; IC95%: 1,52-2,01), raza no blanca raza/etnicidad (OR = 1,16; IC95%: 1,02-1,31), género masculino (OR = 1,25; IC95%: 1,11-1,42), recuentos de células CD4 más altos más cercanos a la muerte (OR = 1,14; IC95%: 1,12-1,16), que no tenían TB (OR = 4,86; IC95%: 3,76-6,29), y que no murieron en un hospital (OR = 2,61; IC95%: 2,31-2,95), estuvieron asociados con probabilidades crecientes de no tener HMDC. La proporción de muertes que no tenían HMDC aumentó de un 18,7% a un 35,1% entre 2014 y 2019. La alta proporción de muertes subregistradas en Río de Janeiro indican que los coeficientes de mortalidad VIH/SIDA en el estado quizás estaban subestimados. Los patrones cambiantes de mortalidad suponen un desafío para las PLHIV, así como para los médicos, a la hora de considerar infección por VIH dentro de un espectro clínico más amplio, al igual que para los agentes de supervisión, con el fin de mejorar el monitoreo de muertes.

Background: In Brazil, mathematical models for deriving estimates and projections of COVID-19 cases have been developed without data on asymptomatic SARS-CoV-2 infection. We estimated the seroprevalence of antibodies to SARS-CoV-2 among blood donors in the State of Rio de Janeiro. Methods: Data were collected on 2,857 blood donors from April 14 to 27, 2020. We report the crude prevalence of antibodies to SARS-CoV-2, the weighted prevalence by the total state population, and adjusted prevalence estimates for test sensitivity and specificity. To establish the correlates of SARS-CoV-2 prevalence, we used logistic regression models. The analysis included period and site of blood collection, sociodemographic characteristics, and place of residence. Results: The proportion of SARS-Cov-2 positive tests without any adjustment was 4.0% (95% CI 3.3-4.7%), and the weighted prevalence was 3.8% (95% CI 3.1-4.5%). Further adjustment by test sensitivity and specificity produced lower estimates, 3.6% (95% CI 2.7-4.4%) and 3.3% (95% CI 2.6-4.1%), respectively. The variable most significantly associated with the crude prevalence was the period of blood collection: the later the period, the higher the prevalence. Regarding socio-demographic characteristics, the younger the blood donors, the higher the prevalence, and the lower the educational level, the higher the odds of a positive SARS-Cov-2 antibody. Similar results were found for the weighted prevalence. Discussion: Although our findings resulted from a convenience sample, they match some basic premises: the increasing trend over time, since the epidemic curve in the state is still on the rise; the higher prevalence among the youngest who are more likely to circulate; and the higher prevalence among the less educated as they have more difficulties in following the social distancing recommendations. Despite the study limitations, it is possible to infer that protective levels of natural herd immunity to SARS-CoV-2 are far from being reached in Rio de Janeiro.

RESUMO: Introdução: A aparente estabilidade da mortalidade por aids no país na última década encobre uma gama de cenários, com dois terços dos estados apresentando taxa padronizada de mortalidade por aids (TPMA) significativamente acima da média nacional e/ou em tendência ascendente. No Rio de Janeiro, a TPMA vem mantendo-se alta e estável ao longo dos anos; atualmente o estado ocupa a segunda posição no ranking nacional desse indicador. Objetivo: Examinar tendências temporais em causas de óbito na busca de padrões diferenciais que contribuam para o entendimento da mortalidade por aids no estado. Metodologia: Foram analisadas causas de óbito em qualquer campo das declarações de óbito constantes do Sistema de Informação sobre Mortalidade (SIM) entre 1999 e 2015 para indivíduos ≥ 15 anos. Doenças cardiovasculares, malignidades não relacionadas à aids, causas externas, diabetes melito e tuberculose foram estabelecidas pela menção ou não de seus códigos conforme a Classificação Estatística Internacional de Doenças e Problemas Relacionados com a Saúde (CID-10) nas declarações de óbito. Modelos lineares generalizados com efeitos mistos foram usados para descrever odds ratios relativas a 1999 e variações anuais médias ajustadas. Resultados: Verificaram-se o aumento proporcional em causas externas e doenças geniturinárias e, sobretudo, o persistente papel desempenhado pela tuberculose, impactando diferencialmente a mortalidade por aids no estado, em um cenário de alta mortalidade por doenças infecciosas. Conclusão: Os achados reforçam a manutenção da tuberculose na mortalidade de pessoas vivendo com HIV/aids (PVHA) no Rio de Janeiro e chamam a atenção para a necessidade de avaliar determinantes individuais atuando na redução da sobrevida desses pacientes, de forma a aprimorar o programa de controle do HIV/aids no estado.

ABSTRACT: Introduction: The trend toward stabilization regarding the AIDS epidemic in Brazil over the past decade hides a very complex scenario, where two-thirds of the Brazilian federative units exhibit AIDS standardized mortality rates (ASMR) significantly above the national average and/or in upward tendency. ASMR in Rio de Janeiro State remains virtually unchanged over the years; the state currently occupies the second position in the national ranking of this indicator. Objective: To assess temporal trends in causes of death searching for differential profiles that could be useful for understanding mortality among patients with HIV in the state. Methodology: Causes of death were analyzed in any field of the death certificates from the Mortality Information System between 1999 and 2015 for individuals ≥ 15 years of age. Cardiovascular diseases, non-AIDS-related cancers, external causes, diabetes mellitus, and tuberculosis were established by the mention or not of their codes according to the 10th edition of International Statistical Classification of Diseases and Related Health Problems (ICD-10) in death certificates. Generalized linear mixed-effects models were used to describe odds ratios in relation to 1999 and adjusted mean annual variations. Results: The results point to the emerging role of external causes and genitourinary diseases and the persistent role played by tuberculosis, differentially affecting AIDS mortality in the state, in a scenario of high mortality due to infectious diseases. Conclusion: These data suggest that tuberculosis remains a major cause of death among people living with HIV/AIDS (PLWHA) in Rio de Janeiro, highlighting the need for studies that identify individual-level factors impacting their survival, thus improving local HIV/AIDS control measures.

BACKGROUND:The natural history of HIV infection has changed dramatically after the introduction of highly active antiretroviral therapy. Currently, opportunistic illnesses still represent a major cause of death and hospitalization in this population. In this study, we review the trends in opportunistic illnesses incidence rates and compare the results observed in high-income settings with that for low/middle-income settings, with special attention given to studies from Brazil.METHODS:We systematically searched Pubmed, Web of Science, Lilacs and Google scholar for publications on HIV associated opportunistic illness. Studies reporting rates based on person-time for all opportunistic illnesses and/or the three opportunistic infections of interest, namely,Pneumocystis cariniipneumonia, cerebral toxoplasmosis, and Mycobacterium aviumcomplex were included.RESULTS:Significant reductions in the incidence rates were demonstrated for opportunistic illnesses overall and also for the specific opportunistic infections included in the present study, both in high and low/middle-income settings. Out of the 37 studies included in the present review, almost 70% were from high-income settings. All the studies conducted in low/middle-income settings were single center studies and four were from Brazil. We found no study from Brazil reporting annual incidence rates of opportunistic illnesses.CONCLUSIONS:Opportunistic illnesses remain an important public health problem. To better guide health policies in low/middle-income settings, multicenter cohort studies should be encouraged. Studies from Brazil are urgently needed to assess the current burden of opportunistic illnesses in our population and to support the planning of HIV/AIDS health care services organization.

The worldwide elderly population is expected to grow by an additional 694 million people by 2025. By that time, there will be approximately two billion elderly people in the world, most of whom (80%) will be living in developing countries. Based on recent estimates, this population will number over 40 million in 2030 in Brazil and a consequent increase in governmental spending for this population can be expected. Since highly active antiretroviral therapy became available in the mid-1990s, the life expectancy of people living with HIV has increased significantly. Approximately 12 million life years were added to the world between 1996 and 2008 as a consequence of wider access to highly active antiretroviral therapy. In Brazil, the incidence of AIDS among the population aged >50 years doubled between 1996 and 2006. The development of antiretroviral therapy has allowed individuals diagnosed at a younger age to live longer, which partially explains the aging tendency associated with the HIV/AIDS epidemic. It is estimated that by 2015, subjects aged >50 years will represent 50% of the people living with HIV undergoing clinical treatment. This scenario presents some challenges, including the fact that the diagnosis of HIV tends to be delayed in older patients compared to younger patients because the symptoms of HIV can be confused with those of other common diseases among the elderly and also because healthcare professionals do not consider this population to be at high risk for HIV infection. In regard to the individuals diagnosed with HIV, a further challenge is presented by the morbidity normally associated with aging. Finally, the elderly also exhibit higher susceptibility to the toxic effects and pharmacological interactions of medications. The present article reviews the literature regarding the profile of HIV infection among individuals aged >50 years focusing on practical features related to the clinical approach and long-term follow-up of this population.

As lesões intraepiteliais escamosas de alto grau (HSIL) são precursoras do câncer do colo do útero, com maior risco de ocorrência e desenvolvimento em mulheres HIV+. Neste trabalho, estimamos e comparamos o desempenho do exame citológico e da captura híbrida II no rastreamento das lesões precursoras em mulheres HIV+. A população de estudo compreendeu mulheres acompanhadas na coorte prospectiva aberta do Instituto de Pesquisa Clínica Evandro Chagas da Fundação Oswaldo Cruz (IPEC/Fiocruz). A colposcopia e histologia foram consideradas conjuntamente na definição do teste de referência. O exame citológico apresentou sensibilidade de 31,8% e especificidade de 95,5%, enquanto a captura híbrida II apresentou maior sensibilidade (100%) e menor especificidade (52%). As razões de verossimilhança para o teste positivo e negativo foram estimadas em 7,1 e 0,7 para o exame citológico e em 2,1 e 0,0 para a captura híbrida II, respectivamente.

HIV-infected women are at increased risk of developing high-grade squamous intraepithelial lesions (HSIL), the precursor lesions for cervical cancer. This study estimated and compared the performance of cytology and hybrid capture II in screening for precursor lesions of cervical cancer among HIV-infected women. The study population consisted of women from the open prospective cohort at the Evandro Chagas Clinical Research Institute, Oswaldo Cruz Foundation (IPEC/Fiocruz). Colposcopy and histology were considered jointly in defining the gold standard. Cytology showed 31.8% sensitivity and 95.5% specificity, while hybrid capture II showed higher sensitivity (100%) and lower specificity (52%). The positive likelihood ratio was 7.1 for cytology and 2.1 for hybrid capture II, while the negative likelihood ratio was 0.7 for cytology and 0.0 for hybrid capture II.
