Associação entre escolaridade e taxa de mortalidade por dengue no Brasil / Association between schooling and mortality rate from dengue in Brazil / Asociación entre educación y tasa de mortalidad por dengue en Brasil

A dengue pode estar associada a variáveis de nível individual, como escolaridade, aumentando o risco de adoecimento. O objetivo deste trabalho é analisar as disparidades da mortalidade por dengue entre os menos e mais escolarizados no Brasil entre os anos de 2010 e 2018. Este é um estudo do tipo ecológico retrospectivo das diferenças na taxa de mortalidade por dengue entre menos e mais escolarizados no Brasil, através das taxas de mortalidade por dengue geral, por idade, sexo e Unidade Federativa (UF). Um procedimento de bootstrap e imputação múltipla para a variável escolaridade foram implementados de modo a considerar a estrutura multinível em cada UF dos dados ao longo dos anos. Para cada banco agregado gerado, foi ajustado um modelo de Poisson multinível. A melhoria na escolaridade da população brasileira não refletiu na diminuição da mortalidade por dengue. Houve um aumento na taxa de mortalidade por dengue no Brasil e um crescimento da diferença de taxas de mortalidade entre menos e mais escolarizados. Independentemente do processo de imputação, os resultados mostraram maiores taxas de mortalidade por dengue entre os menos escolarizados. A baixa escolaridade afetou de forma mais pronunciada os mais jovens.

Dengue may be associated with individual level variables, such as schooling, increasing the risk of illness. The objective of this study is to analyze the disparities in dengue mortality among the least and the most educated in Brazil, from 2010 to 2018. This is a retrospective ecological study of the differences in the mortality rate due to dengue between the less and the more educated people in Brazil, according to the mortality rates due to general dengue, by age, sex, and Federative Unit (UF). A bootstrap and multiple imputation procedure for the variable schooling was implemented to consider the multilevel structure of the data from each UF over the years. For each aggregate bank generated, a multilevel Poisson model was adjusted. The improvement in the education level of the Brazilian population did not reflect on the decrease in mortality from dengue. There was an increase in the mortality rate from dengue in Brazil and an increase in the difference in mortality rates between less and more educated. Regardless of the imputation process, the results showed higher mortality rates from dengue among the less educated. Low schooling affected younger people more pronouncedly.

El dengue puede estar asociado a variables de nivel individual como la educación, aumentando el riesgo de enfermarse. El objetivo de este trabajo es analizar las disparidades de la mortalidad por dengue entre las personas con menor y mayor nivel educativo en Brasil entre los años 2010 y 2018. Estudio del tipo ecológico retrospectivo de las diferencias en la tasa de mortalidad por dengue entre las personas con menor y mayor nivel educativo en Brasil, a través de las tasas de mortalidad por dengue general, por edad, género y Unidad Federativa (UF). Se implementó un procedimiento de bootstrap y de imputación múltiple para la variable de educación para considerar la estructura multinivel en cada UF de los datos a lo largo de los años. Para cada banco agregado generado, se ajustó un modelo de Poisson multinivel. La mejora en la educación de la población brasileña no se reflejó en la disminución de la mortalidad por dengue. Hubo un aumento en la tasa de mortalidad por dengue en Brasil y un crecimiento de la diferencia en las tasas de mortalidad entre las personas con menor y mayor nivel educativo. Independientemente del proceso de imputación, los resultados mostraron mayores tasas de mortalidad por dengue entre los menos educados. El bajo nivel de educación afectó de forma más pronunciada a los más jóvenes.

Excesso de mortes durante a pandemia de COVID-19: subnotificação e desigualdades regionais no Brasil / Excess deaths during the COVID-19 pandemic: underreporting and regional inequalities in Brazil / Exceso de muertes durante la pandemia de COVID-19: subnotificación y desigualdades regionales en Brasil

O Brasil é um dos países mais afetados pela pandemia de COVID-19 e o real número de mortes pela doença torna o cenário ainda mais desafiador. O objetivo deste estudo foi estimar o excesso de mortes e suas diferenças em adultos com 20 anos e mais em Manaus (Amazonas), Fortaleza (Ceará), Rio de Janeiro e São Paulo, de acordo com o local de ocorrência do óbito, características demográficas e trajetória ao longo do tempo. Os dados foram obtidos no Sistema de Informações sobre Mortalidade e na Central de Informações do Registro Civil Nacional. As estimativas de óbitos esperados foram obtidas por meio de modelos aditivos generalizados quasi-Poisson com ajuste de sobredispersão. Entre 23 de fevereiro e 13 de junho de 2020, foram registradas 74.410 mortes naturais nas quatro cidades, com excesso de mortes de 46% (IC95%: 44-47). O maior excesso de mortes ocorreu em Manaus, 112% (IC95%: 103-121), seguido por Fortaleza, 72% (IC95%: 67-78), Rio de Janeiro, 42% (IC95%: 40-45) e São Paulo, 34% (IC95%: 32-36). O excesso de mortes foi maior nos homens e não significativo nas Semanas Epidemiológicas (SE) 9-12, exceto em São Paulo, 10% (IC95%: 6-14). Em geral, o pico de mortes excedentes ocorreu nas SE 17-20. O excesso de mortes não explicado diretamente pela COVID-19 e de mortes em domicílios/via pública foi alto, especialmente em Manaus. A elevada porcentagem de mortes excedentes, de mortes não explicadas diretamente pela COVID-19 e de mortes fora do hospital sugerem alta subnotificação de mortes por COVID-19 e reforça a extensa dispersão do SARS-CoV-2, como também a necessidade da revisão de todas as causas de mortes associadas a sintomas respiratórios pelos serviços de vigilância epidemiológica.

Brazil is one of the most heavily impacted countries by the COVID-19 pandemic, and the real number of deaths from the disease makes the scenario even more challenging. This study aimed to estimate the excess deaths and their differences in adults 20 years and older in Manaus (Amazonas State), Fortaleza (Ceará State), Rio de Janeiro, and São Paulo, according to place of death, demographic characteristics, and trajectory over time. The data were obtained from the Mortality Information System and the Central Information Office of the National Civil Registry. The estimates of expected deaths were obtained from quasi-Poisson generalized additive models, adjusting for overdispersion. From February 23 to June 13, 2020, 74,410 natural deaths were recorded in the four cities, with 46% excess deaths (95%CI: 44-47). The largest amount of excess deaths was in Manaus, with 112% (95%CI: 103-121), followed by Fortaleza with 72% (95%CI: 67-78), Rio de Janeiro with 42% (95%CI: 40-45), and São Paulo with 34% (95%CI: 32-36). Excess deaths were greater in males and non-significant in Epidemiologic Weeks (EW) 9-12, except in São Paulo, 10% (95%CI: 6-14). The peak in excess deaths generally occurred in EW 17-20. The number of excess deaths not explained directly by COVID-19 and deaths at home or on public byways is high, especially in Manaus. The high percentages of excess deaths, deaths not explained directly by COVID-19, and deaths outside the hospital suggest high underreporting of deaths from COVID-19 and reinforce the extensive spread of SARS-CoV-2, as well as the need for epidemiological surveillance services to review all causes of deaths associated with respiratory symptoms.

El exceso de muertes fue mayor en hombres y no significativo en las Semanas Epidemiológicas (SE) 9-12, excepto en São Paulo, 10% (IC95%: 6-14). En general, el pico de muertes excedentarias se produjo en las SE 17-20. El exceso de muertes no explicado directamente por la COVID-19 y de las muertes en domicilios/vía pública fue alto, especialmente en Manaus. El elevado porcentaje de muertes excedentarias, de muertes no explicadas directamente por la COVID-19, y de muertes fuera del hospital, sugieren una alta subnotificación de muertes por COVID-19 y refuerza la extensa dispersión del SARS-CoV-2, así como también la necesidad de una revisión de todas las causas de muertes asociadas a síntomas respiratorios, por parte de los servicios de vigilancia epidemiológica.

Prevalência e fatores associados ao aborto induzido no ingresso em uma coorte de mulheres vivendo com HIV/aids, Rio de Janeiro, Brasil, 1996-2016 / Prevalencia y factores asociados al aborto inducido en el ingreso en una cohorte de mujeres que viven con VIH/SIDA, Río de Janeiro, Brasil, 1996-2016 / Prevalence of induced abortion and associated factors in a cohort of women living with HIV/AIDS, Rio de Janeiro, Brazil, 1996-2016

O objetivo deste estudo é verificar a prevalência e os fatores associados ao aborto induzido no ingresso em uma coorte de mulheres vivendo com HIV/aids, no Município do Rio de Janeiro, Brasil, no período 1996-2016. O critério de elegibilidade para o ingresso na coorte era ser do sexo feminino ao nascimento, ter mais de 18 anos de idade e ter infecção comprovada pelo HIV. Na visita inicial, dados sobre aspectos sexuais, reprodutivos, comportamentais e da infecção pelo HIV foram obtidos durante entrevista face a face com o médico assistente. Foi calculada a prevalência de aborto induzido na vida e verificados os fatores associados ao aborto induzido por meio de regressão logística múltipla, para o total de mulheres e entre aquelas com gestação prévia. Do total de mulheres, 30,4% referiram algum aborto induzido na vida, sendo este valor de 33,5% em mulheres com gestação prévia. A frequência de aborto induzido relatado apresentou queda significativa no período analisado (41,7% de 1996-2000 vs. 22,5% de 2011-2016, p < 0,001). Os fatores associados ao aborto induzido, tanto para o total de mulheres quanto para aquelas com gestação prévia, foram o aumento da idade, escolaridade mais elevada, número de parceiros sexuais na vida ≥ 5, gestação na adolescência, uso de qualquer droga ilícita na vida e período de ingresso na coorte após 2005. Mudanças no perfil socioeconômico, sexual, reprodutivo e da infecção pelo HIV são explicações possíveis para a redução da prática do aborto no período. Estudos que utilizem métodos de aferição direta do aborto devem ser conduzidos em outras populações, para confirmar a tendência de queda do aborto induzido no país e seus determinantes.

El objetivo de este estudio es verificar la prevalencia y los factores asociados al aborto inducido en el ingreso en una cohorte de mujeres, que viven con VIH/sida, en el municipio de Rio de Janeiro, durante el período 1996-2016. El criterio de elegibilidad para el ingreso en la cohorte era ser del sexo femenino al nacer, tener más de 18 años de edad y sufrir una infección comprobada por VIH. En la visita inicial, datos sobre aspectos sexuales, reproductivos, comportamentales y de infección por el VIH se obtuvieron durante la entrevista cara a cara con el médico asistente. Se calculó la prevalencia del aborto inducido en la vida y se verificaron los factores asociados al aborto inducido mediante regresión logística múltiple, para el total de mujeres y entre aquellas con gestación previa. Del total de mujeres, un 30,4% refería algún aborto inducido en la vida, siendo ese valor de un 33,5% en mujeres con gestación previa. La frecuencia de aborto inducido relatado presentó una caída significativa durante el período analizado (un 41,7% en el período 1996-2000 vs. 22,5% en el período 2011-2016, p < 0,001). Los factores asociados al aborto inducido, tanto para el total de mujeres, como para aquellas con gestación previa, fueron el aumento de la edad de la mujer, escolaridad más elevada, número de parejas sexuales en la vida ≥ 5, gestación en la adolescencia, consumo de cualquier droga ilícita en la vida y período de ingreso en la cohorte tras 2005. Cambios en el perfil socioeconómico, sexual, reproductivo y de infección por VIH son explicaciones posibles para la reducción de la realización de abortos durante el período. Se deben llevar a cabo estudios que utilicen métodos de medición directa del aborto en otras poblaciones para confirmar la tendencia de caída del aborto inducido en el país y sus determinantes.

The aim of this study was to verify the prevalence of induced abortion and associated factors at the time of inclusion in a cohort of women living with HIV/AIDS in the city of Rio de Janeiro, Brazil, from 1996 to 2016. Eligibility criteria for inclusion in the cohort were female sex at birth, age 18 years and older, and confirmed HIV infection. At the baseline visit, data on sexual, reproductive, and behavioral aspects and HIV infection were obtained through a face-to-face interview with the attending physician. Lifetime prevalence of induced abortion was calculated, and factors associated with induced abortion were verified by multiple logistic regression for all the women and for those with previous pregnancy. In the entire cohort of women, 30.4% reported a history of induced abortion, compared to 33.5% in women with previous pregnancy. Frequency of reported induced abortion showed a significant reduction during the period (41.7% in 1996-2000 versus 22.5% in 2011-2016, p < 0.001). Factors associated with induced abortion, both for the entire cohort and for the women with previous pregnancy, were age, schooling, ≥ 5 lifetime sexual partners, teenage pregnancy, lifetime use of any illicit drug, and inclusion in the cohort after the year 2005. Changes in the socioeconomic, sexual, reproductive, and HIV infection profile are possible explanations for the reduction in abortions during the period. Studies that use direct methods to measure abortion should be conducted in other populations to confirm the downward trend in induced abortion and its determinants in Brazil.

Hybrid capture as a tool for cervical lesions screening in HIV-infected women: insights from a Brazilian cohort

ABSTRACT Introduction: Cervical cancer remains an important burden for HIV-infected women in the era of combination antiretroviral therapy. Recommendations for cervical screening in these women diverge and may include high-risk HPV (HRHPV) testing. We aimed to evaluate the clinical usefulness of a single HRHPV testing for cervical screening of HIV-infected women. Methods: 723 HIV-infected women from a Brazilian prospective cohort were included between 1996 and 2012. Inclusion criteria were: normal cervical cytology at baseline and having a HRHPV-test at baseline. We calculated incidence rates of any squamous intraepithelial lesion (SIL) and high grade SIL+ (HSIL+) and negative predictive values (NPV) within 12 and 36 months. Hazard Ratios were obtained using Cox proportional hazards regression models. Results: Incidence rate for both outcomes was low (9.9 cases per 100 PY [95% CI 8.8-11.0] for any SIL and 1.3 cases per 100 PY [95% IC 0.9-1.8] for HSIL+). Women with a HRHPV positive status at baseline had 1.7-fold (95% CI 1.3-2.2) and 3.2-fold (95% CI 1.5-7.1) increased risk of presenting any SIL and HSIL+, respectively, during follow-up. Negative-HRHPV test presented high NPV for both periods and outcomes (any SIL: 92.4% [95% CI 89.7-94.6] for 12 months and 80.9% [95% CI 77.2-84.3] for 36 months; and HSIL+: 99.8% [95% CI 98.9-100.0] for 12 months and 99.0 [95% CI 97.6-99.7] for 36 months). Conclusions: Incidence of any and high grade cytological abnormality was significantly higher among HIV-infected women with positive-HRHPV test. A single negative-HRHPV test helped reassure follow-up free of cytological abnormalities through three years of follow-up in HIV-infected women with negative cytology.

The Fraction of Cancer Attributable to Ways of Life, Infections, Occupation, and Environmental Agents in Brazil in 2020.

Many human cancers develop as a result of exposure to risk factors related to the environment and ways of life. The aim of this study was to estimate attributable fractions of 25 types of cancers resulting from exposure to modifiable risk factors in Brazil. The prevalence of exposure to selected risk factors among adults was obtained from population-based surveys conducted from 2000 to 2008. Risk estimates were based on data drawn from meta-analyses or large, high quality studies. Population-attributable fractions (PAF) for a combination of risk factors, as well as the number of preventable deaths and cancer cases, were calculated for 2020. The known preventable risk factors studied will account for 34% of cancer cases among men and 35% among women in 2020, and for 46% and 39% deaths, respectively. The highest attributable fractions were estimated for tobacco smoking, infections, low consumption of fruits and vegetables, excess weight, reproductive factors, and physical inactivity. This is the first study to systematically estimate the fraction of cancer attributable to potentially modifiable risk factors in Brazil. Strategies for primary prevention of tobacco smoking and control of infection and the promotion of a healthy diet and physical activity should be the main priorities in policies for cancer prevention in the country.

Predictors of early menopause in HIV-infected women: a prospective cohort study.

OBJECTIVE: This study sought to investigate the age at natural menopause and its predictors in a cohort of human immunodeficiency virus (HIV)-infected women in Rio de Janeiro, Brazil. STUDY DESIGN: HIV-infected women ≥30 years of age were included. Menopause was defined as having ≥1 year since the last menstrual period. Early age at natural menopause was defined as the onset of menopause at ≤45 years of age. Multivariate Cox proportional hazards analysis was applied. RESULTS: A total of 667 women were included, and the median age at baseline was 34.9 years (interquartile range, 30.9-40.5 years). In all, 507 (76%) women were premenopausal, and 160 (24%) reached menopause during the observational period; of these, 36 of 160 (27%) had early menopause. The median age at natural menopause was 48 years (interquartile range, 45-50 years). Menarche at <11 years of age (hazard ratio [HR], 2.03; 95% confidence interval [CI], 1.23-3.37), cigarette smoking during the observational period (HR, 1.59; 95% CI, 1.08-2.33), chronic hepatitis C virus (HCV) infection (HR, 2.53; 95% CI, 1.27-5.07), and CD4 count <50 cells/mm(3) (HR, 3.07; 95% CI, 1.07-8.80) were significantly associated with an earlier age at natural menopause. The magnitudes of the effects of menarche at <11 years of age (HR, 2.7; 95% CI, 1.23-5.94), cigarette smoking during the observational period (HR, 3.00; 95% CI, 1.39-6.45), chronic HCV infection (HR, 6.26; 95% CI, 2.12-18.52), and CD4 count <50 cells/mm(3) (HR, 6.64; 95% CI, 1.91-23.20) were much higher and significantly associated with early natural menopause. CONCLUSION: Early natural menopause was frequent among the HIV-infected women. In addition to menarche and cigarette smoking, which are menopausal factors among women in general, HIV-related immunodeficiency and chronic HCV were additional predictors for an earlier age at natural menopause. Adequate management of HIV in women is critical, as early onset of menopause has been associated with increased morbidity and mortality.

Cascade of access to interventions to prevent HIV mother to child transmission in the metropolitan area of Rio de Janeiro, Brazil

OBJECTIVES: To describe the access to the interventions for the prevention of Human Immunodeficiency Virus (HIV) mother to child transmission and mother to child transmission rates in the outskirts of Rio de Janeiro, from 1999 to 2009. METHODS: This is a retrospective cohort study. Prevention of HIV mother to child transmission interventions were accessed and mother to child transmission rates were calculated. RESULTS: The study population is young (median: 26 years; interquartile range: 22.0-31.0), with low monthly family income (40.4% up to one Brazilian minimum wage) and schooling (62.1% less than 8 years). Only 47.1% (n = 469) knew the HIV status of their partner; of these women, 39.9% had an HIV-seronegative partner. Among the 1259 newborns evaluated, access to the antenatal, intrapartum and postpartum prevention of HIV mother to child transmission components occurred in 59.2%, 74.2%, and 97.5% respectively; 91.0% of the newborns were not breastfed. Overall 52.7% of the newborns have benefited from all the recommended interventions. In subsequent pregnancies (n = 289), 67.8% of the newborns received the full package of interventions. The overall rate of HIV vertical transmission was 4.7% and the highest annual rate occurred in 2005 (7.4%), with no definite trend in the period. CONCLUSIONS: Access to the full package of interventions for the prevention of HIV vertical transmission was low, with no significant trend of improvement over the years. The vertical transmission rates observed were higher than those found in reference services in the municipality of Rio de Janeiro and in the richest regions of the country. .

Screening for decreased glomerular filtration rate and associated risk factors in a cohort of HIV-infected patients in a middle-income country.

With the introduction of combined active antiretroviral therapy and the improved survival of HIV-infected patients, degenerative diseases and drug toxicity have emerged as long-term concerns. We studied the prevalence of decreased glomerular filtration rate (GFR) and associated risk factors in a cohort of HIV-infected patients from a middle-income country. Our cross-sectional study included all adult patients who attended an urban outpatient clinic in 2008. GFR was estimated using the CKD-EPI equation. The prevalence ratio (PR) of decreased GFR (defined as <60 mL/min/1.73 m(2)) was estimated using generalizing linear models assuming a Poisson distribution. We analyzed data from 1,970 patients, of which 82.9% had been exposed to ART. A total of 249 patients (12.6%) had a GFR between 60 and 89 mL/min/1.73 m(2), 3.1% had a GFR between 30 and 59, 0.3% had a GFR between 15 and 29, and 0.4% had a GFR <15. Decreased GFR was found in only 74 patients (3.8%). In the multivariate regression model, the factors that were independently associated with a GFR below 60 mL/min/1.73 m(2) were as follows: age ≥ 50 years (PR = 3.4; 95% CI: 1.7-6.8), diabetes (PR = 2.0; 95% CI: 1.2-3.4), hypertension (PR = 2.0; 95% CI: 1.3-3.2), current CD4+ cell count <350 cells/mm3 (PR = 2.1; 95% CI: 1.3-3.3), past exposure to tenofovir (PR = 4.7; 95% CI: 2.3-9.4) and past exposure to indinavir (PR =1.7; 95% CI: 1.0-2.8). As in high-income countries, CKD was the predominant form of kidney involvement among HIV-infected individuals in our setting. The risk factors associated with decreased glomerular filtration were broad and included virus-related factors as well as degenerative and nephrotoxic factors. Despite the potential for nephrotoxicity associated with some antiretroviral drugs, in the short-term, advanced chronic renal disease remains very rare.

Unprotected sex among men who have sex with men living with HIV in Brazil: a cross-sectional study in Rio de Janeiro.

BACKGROUND: Many countries are facing concentrated HIV epidemics among vulnerable populations, including men who have sex with men (MSM). Unprotected anal intercourse (UAI) is the main HIV transmission route among them and its understanding in the different cultures and how it relates to HIV transmission, re-infection and development of HIV antiretroviral resistance has important public health implications. Data on UAI among Brazilian MSM are scarce. This study aims to evaluate the prevalence and associated factors of UAI among HIV-infected MSM who had sex with seronegative or male partners with an unknown serostatus. METHOD: A cross-sectional study nested in a cohort was conducted in Rio de Janeiro, Brazil. The one hundred and fifty five MSM included in the study answered an ACASI interview and provided biological samples. Generalized linear models were used to identify variables associated with UAI. RESULTS: Overall, UAI with an HIV-negative or unknown serostatus male partner was reported by 40.6% (63/155) of MSM. Lifetime sexual abuse or domestic violence was reported by 35.9%, being more frequent among MSM who reported UAI compared to those who did not (P = 0.001). Use of stimulants before sex was reported by 20% of the MSM, being slightly higher among those who reported UAI (27.0% vs. 15.2%; P = 0.072). Commercial sex was frequent among all MSM (48.4%). After multivariate modeling, the report of sexual abuse or domestic violence (OR = 2.70; 95% CI: 1.08-7.01), commercial sex (OR = 2.28; 95% CI: 1.04- 5.10), the number of male sexual partners (p = 0.039) and exclusively receptive anal intercourse (OR = 0.21; 95% CI: 0.06-0.75) remained associated with UAI. CD4 levels, HIV viral load and antiretroviral therapy were not associated with UAI. CONCLUSION: The UAI prevalence found with negative or unknown HIV status partners points out that other interventions are needed as additional prevention tools to vulnerable MSM. The main factors associated with UAI were a lifetime history of violence, commercial sex and the number of male sexual partners. This clustering of different behavioral, health and social problems in this population reinforce the need of a comprehensive approach on treating and preventing HIV among MSM.

Breast cancer in a cohort of human immunodeficiency virus (HIV)-infected women from Rio de Janeiro, Brazil: a cases series report and an incidence rate estimate.

Highly active antiretroviral therapy (HAART) has changed the morbidity pattern affecting HIV-infected individuals to include non-AIDS-defining cancers. We describe the breast cancer cases occurring in a cohort of 860 HIV-infected women followed in Rio de Janeiro, Brazil, and estimate the incidence rate of breast cancer for this population. Nine cases were identified; median age at diagnosis was 46 years. Median survival after breast cancer diagnosis was 12 months. Breast cancer diagnosis was made within 2 to 15 years of HIV-infection diagnosis. At breast cancer diagnosis, CD4 counts ranged from 135 to 782 cells/mm3; six women were receiving HAART. Histological analysis indicated infiltrating ductal carcinoma in all cases. The incidence rate of breast cancer was 133 cases per 100,000 persons-year. Patients from our case series were late diagnosed with breast cancer and thus suffered from worse prognosis. Strategies targeting earlier diagnosis and prompt initiation of treatment are needed.

Factors associated with increased prevalence of human papillomavirus infection in a cohort of HIV-infected Brazilian women.

OBJECTIVES: Human papillomavirus (HPV) infection is a major risk factor for cervical disease. Using baseline data from the HIV-infected cohort of Evandro Chagas Clinical Research Institute at Fiocruz, Rio de Janeiro, Brazil, factors associated with an increased prevalence of HPV were assessed. METHODS: Samples from 634 HIV-infected women were tested for the presence of HPV infection using hybrid capture II and polymerase chain reaction. Prevalence ratios (PR) were estimated using Poisson regression analysis with robust variance. RESULTS: The overall prevalence of HPV infection was 48%, of which 94% were infected with a high-risk HPV. In multivariate analysis, factors independently associated with infection with high-risk HPV type were: younger age (<30 years of age; PR 1.5, 95% confidence interval (CI) 1.1-2.1), current or prior drug use (PR 1.3, 95% CI 1.0-1.6), self-reported history of HPV infection (PR 1.2, 95% CI 0.96-1.6), condom use in the last sexual intercourse (PR 1.3, 95% CI 1.1-1.7), and nadir CD4+ T-cell count <100cells/mm(3) (PR 1.6, 95% CI 1.2-2.1). CONCLUSIONS: The estimated prevalence of high-risk HPV-infection among HIV-infected women from Rio de Janeiro, Brazil, was high. Close monitoring of HPV-related effects is warranted in all HIV-infected women, in particular those of younger age and advanced immunosuppression.

Assessing sexually transmitted infections in a cohort of women living with HIV/AIDS, in Rio de Janeiro, Brazil.

A cohort of 458 HIV-positive women under antiretroviral therapy has been followed at a reference hospital in Rio de Janeiro, Brazil. Most of them belong to impoverished social strata. Patients were screened for sexually transmitted infections (STIs) and gynaecologic conditions. Some STIs were found to be uncommon (e.g. chlamydial and gonococcal infections), while some conditions (bacterial vaginosis) and STIs, e.g. hepatitis B and human papilloma virus (HPV) infection, were found to be quite prevalent. The latter is of special concern, due to the high prevalence of HIV/HPV co-infection ( approximately 51%) and its association with severe immunodeficiency, in a context of unacceptable high levels of uterine cancer and uneven gynaecological care. HIV-positive women are in need of comprehensive health services, including high-quality, regular, gynaecologic care in order to diagnose and treat lower genital tract infections and prevent the evolution of HPV-related lesions. Reproductive counselling should be a part of this approach.
