Assessing the underreporting of deaths among people living with HIV in Rio de Janeiro, Brazil, from 2014 to 2019.

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.

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.

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.

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.

DBCollHIV: a database system for collaborative HIV analysis in Brazil.

We developed a database system for collaborative HIV analysis (DBCollHIV) in Brazil. The main purpose of our DBCollHIV project was to develop an HIV-integrated database system with analytical bioinformatics tools that would support the needs of Brazilian research groups for data storage and sequence analysis. Whenever authorized by the principal investigator, this system also allows the integration of data from different studies and/or the release of the data to the general public. The development of a database that combines sequences associated with clinical/epidemiological data is difficult without the active support of interdisciplinary investigators. A functional database that securely stores data and helps the investigator to manipulate their sequences before publication would be an attractive tool for investigators depositing their data and collaborating with other groups. DBCollHIV allows investigators to manipulate their own datasets, as well as integrating molecular and clinical HIV data, in an innovative fashion.

Access to antiretroviral treatment in Latin American countries and the Caribbean.

OBJECTIVES: To assess the access to antiretroviral therapy in the Latin America and Caribbean region and the main issues involved. METHODS: A review of National AIDS Programmes reports, published studies on HIV access to antiretroviral drugs, and personal communications from National AIDS Programmes in the region. RESULTS: Most countries have, or are in the process of developing, laws and regulations to ensure better access to antiretroviral drugs for people in need. However, there are still many countries that either have not implemented policies or do not have policies. There has been an important decrease in the cost of drugs, but prices are still too high for all countries to afford them. The benefits in decreased mortality and hospitalizations in the countries with high coverage are significant. The number of people receiving antiretroviral therapy has been estimated to be close to 170,000 individuals; however, this figure only represents a fraction of the people in need in the region. Some different strategies will have to be implemented in order to increase coverage. CONCLUSION: Renewed efforts are needed from both governments and international community organizations to strengthen the health services and increase access to antiretroviral drugs.

Dramatic improvement in survival among adult Brazilian AIDS patients.

BACKGROUND: Since the last study of survival time among Brazilian AIDS patients, care has improved steadily, culminating in a controversial policy of universal free access to triple antiretroviral treatment since 1996. This large, national study examined how these changes have impacted survival. METHODS: Using national data for cases diagnosed in 1995 and 1996, we randomly selected 3930 adult AIDS cases from 18 cities in seven states representing all regions of Brazil. Trained abstracters reviewed medical records, determining dates of diagnosis and death or last contact, exposure category, treatment, and demographics. After review, 2821 cases met the inclusion criteria and were available for Kaplan-Meier and proportional hazards analysis. Data from the earlier study were re-analyzed for comparison. RESULTS: Median survival was 5 months for cases diagnosed in the 1980s, 18 months for those diagnosed in 1995, and 58 months for those diagnosed in 1996. Predictors of longer survival in univariate analysis included antiretroviral treatment, year of diagnosis, higher education, sexual exposure category, female sex, and Pneumocystis carinii pneumonia prophylaxis. In multivariate analysis, the predictive value of most of these was attenuated or disappeared, leaving antiretroviral treatment as the main predictor of survival. CONCLUSIONS: Survival time has increased substantially for adult Brazilian AIDS patients. The timing of these gains and analysis of the predictors of survival both indicate antiretroviral treatment as the cause. These findings demonstrate that universal access to antiretroviral treatment in a developing country can produce benefits on the same scale as in richer countries.

Prevalence of mutations related to HIV-1 antiretroviral resistance in Brazilian patients failing HAART.

BACKGROUND: Current guidelines for antiretroviral (ARV) therapy recommend at least triple-drug combination, the so-called highly active antiretroviral therapy (HAART). Not all patients respond to HAART and the development of drug resistance remains one of the most serious obstacles to sustained suppression of HIV. OBJECTIVE: In an attempt to correlate the HIV therapeutic failure with reverse transcriptase (RT) and protease resistance mutations, we describe the ARV resistance profile in patients failing HAART in Brazil. We studied 267 Brazilian HIV-1 infected patients failing HAART looking for mutations in RT and protease genes. The mutation profile of the viruses infecting these individuals were deduced and correlated to laboratorial parameters. STUDY DESIGN: Two different HIV-1 genomic regions were targeted for PCR amplification, the protease (pro) and pol RT (palm finger region) genes. The mutations related to drug resistance in RT gene was analyzed using a line probe assay (LIPA(R)) and pro amino acids positions 82 and 90 were screened through RFLP using HincII restriction digestion. RESULTS: There was strong correlation between the mutation in the pro and RT genes and therapeutic failure. The main mutation found in RT gene was the M184V (48%) followed by T69D/N (47%), T215Y/F (46%), M41L (39%), and L74V (7%). In the pro gene the main mutation found was L90M (26%) followed by dual substitution in L90M and V82A (6%). All mutations profiles matched very well with the patients drug regimen. CONCLUSIONS: This study has shown that 84.7% of HIV infected subjects failing HAART for more than 3 months presented viral genomic mutations associated with drug resistance.

Comportamento de risco dos conscritos do Exército Brasileiro, 1998: uma apreciaçäo da infecçäo pelo HIV segundo diferenciais sócio-econômicos / Socioeconomic differences in HIV risk behavior among Brazilian Military conscripts

Uma pesquisa de comportamento de risco ao HIV foi conduzida entre conscritos (17-20 anos) do Exército em 1998. A amostra (30.318) foi selecionada em três estratos: 1) municípios das regiöes Norte e Centro-Oeste (N/CO); 2) municípios da regiäo Sul (S); 3) municípios dos estados do Rio de Janeiro e Säo Paulo (RJ/SP), estimando-se a prevalência de infecçäo pelo HIV em cada estrato. O objetivo foi o de apreciar os resultados por nível sècio-econômico (NSE). A análise estatística utilizou um índice de comportamento sexual de risco para HIV e modelos de regressäo logística. O estrato N/CO apresentou os piores indicadores - os relativos ao NSE, ao comportamento sexual de risco ou aos problemas relacionados às infecçöes sexualmente transmissíveis (IST) - assim como a maior proporçäo de infectados por HIV. Os melhores indicadores foram encontrados no estrato RJ/SP. O Sul mostrou resultados intermediários. O grau de escolaridade teve papel relevante. Os conscritos com primeiro grau incompleto apresentaram o pior índice de comportamento sexual de risco, o qual se mostrou importante preditor dos problemas relacionados às IST, incluindo a infecçäo por HIV.

SIDA no Brasil, 1982-1988 / AIDS in BRAZIL, 1982-1988

The first five AIDS cases recorded in Brazil occured in 1982 (one in the state of Rio de Janeiro and four in the state of Sao Paulo). The incidence has risen steeply since then, with 914 cases reported in the country in the first seven months of 1988. As in Europe and the United States of América, a large proportion of the cases continue to accur in the great metropolises, although incidences are rising steadily in smaller cities. The hardest hit age group is still that between 25 and 40 years, which is not surprising since almost 80 percent of the cases notified were transmitted by sexual contact. The last three years have been witnessed a considerable increase in pediatric cases caused by perinatal (intrauterine or intrapartum) transmission or by the transfusion of contaminated blood and blood products. Through the Government is making serious efforts to monitor the quality of blood destined for transfusion by screening donors through the ELISA method, the prevalence of infection by the human immunodeficiency virus was high before a technique for its detection became available, and many hemophiliacs and other transfusion recipients will continue to fall prey to the disease. Several activities are under way to reduce the risk of infection for intravenous drug users
