RESUMO

Background: HIV incidence estimation is critical for monitoring the HIV epidemic dynamics and the effectiveness of public health prevention interventions. We aimed to identify sexual and gender minorities (SGM) with recent HIV infections, factors associated with recent HIV infection, and to estimate annualised HIV incidence rates. Methods: Cross-sectional multicentre study in HIV testing services in Brazil and Peru (15 cities). Inclusion criteria: 18+ years, SGM assigned male at birth, not using pre-/post-exposure prophylaxis. We identified recent HIV infection using the Maxim HIV-1 LAg-Avidity EIA assay as part of a recent infection testing algorithm (RITA). Annualized HIV incidence was calculated using the UNAIDS/WHO incidence estimator tool. Multivariable logistic regression models were used to estimate factors associated with recent HIV infection. Trial registration: NCT05674682. Findings: From 31-Jan-2021 to 29-May-2022, 6899 individuals participated [Brazil: 4586 (66.5%); Peru: 2313 (33.5%)]; 5946 (86.2%) cisgender men, 751 (10.9%) transgender women and 202 (2.9%) non-binary/gender diverse. Median age was 27 (IQR: 23-34) years. HIV prevalence was 11.4% (N = 784/6899); 137 (2.0%) SGM were identified with recent HIV infection. The overall annualized HIV incidence rate was 3.88% (95% CI: 2.86-4.87); Brazil: 2.62% (95% CI: 1.78-3.43); Peru: 6.69% (95% CI: 4.62-8.69). Participants aged 18-24 years had higher odds of recent HIV infection compared to those aged 30+ years in both countries. Interpretation: Our results highlight the significant burden of HIV epidemic among SGM in large urban centres of Brazil and Peru. Public health policies and interventions to increase access to effective HIV prevention methods such as PrEP are urgently needed in Latin America. Funding: Unitaid, WHO (Switzerland), Ministry of Health from Brazil and Peru.

RESUMO

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.


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.

RESUMO

Purpose: Worldwide, the burden of adverse health conditions is substantial among travestis and transgender women (trans women). Transcendendo, the first trans-specific cohort in a low- or middle-income country, is an open cohort established in August 2015 to longitudinally evaluate the health aspects of trans women aged ≥18 years in Rio de Janeiro, Brazil. Methods: Study visits occur on an annual basis. Data on sociodemographics, behavioral, gender transition, affirmation procedures, hormone use, discrimination, violence, clinical and mental health, HIV prevention, and care (for those HIV-infected) are collected. Physical examination, anthropometric measurements, and laboratory tests are performed. Results: As of July 2017, 322 trans women were enrolled in the cohort with a median age of 31.5 years (interquartile range 25.7-39.5), of whom 174 (54%) were HIV-infected. The Transcendendo baseline information reinforces the scenario of marginalization and deprivation surrounding trans women. Most participants had low income (62.0% were living with below US$ 10.00/day), showed a very high engagement in sex work (78.6%), and reported increased occurrence of sexual (46.3%) and physical (54.0%) violence. Pre-exposure peophylaxis (PReP) was used by 18.8% of the HIV-uninfected trans women, only through research participation. Positive screening for depression (57.8%) and problematic use of tobacco (56.6%), cannabis (28.9%), cocaine (23.8%), and alcohol (21.5%) were high. Almost all participants (94.8%) reported hormone use at some point, mostly without medical supervision (78.7%). Conclusion: Our results describe a context of exclusion experienced by trans women, exposing vulnerabilities of this population in a middle-income country, with poor access to trans-specific care, HIV prevention and care, and mental health care. Addressing transgender experiences and needs can help the development of strategies to diminish stigma, improve health care environment, guide future research on trans morbidities, substance use, and trans-specific interventions to support health-related recommendations. Ultimately, it contributes to close the gaps concerning transgender health and reinforces that trans care cannot be disentangled from the social environment that surrounds trans women.

RESUMO

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.

RESUMO

Brazil has a concentrated HIV epidemic and men who have sex with men (MSM) are disproportionately affected. Yet, no data is available on the HIV care cascade for this population. This study aimed to assess the HIV care cascade among MSM newly diagnosed through innovative testing strategies in Rio de Janeiro. Data from 793 MSM and travestites/transgender women (transwomen) tested for HIV at a non-governmental LGBT organization and a mobile testing unit located at a gay friendly venue were analyzed. A 12-month-after-HIV-diagnosis-censored cohort was established using CD4, viral load and combination antiretroviral therapy (cART) longitudinal data from those diagnosed with HIV. A cross-sectional HIV care cascade was built using this data. The relative risks of achieving each cascade-stage were estimated using generalized linear models according to age, self-declared skin-color, education, history of sexually transmitted diseases (STD), drug use and prior HIV testing. From Jan-2013 to Jan-2014, 793 MSM and transwomen were tested, 131 (16.5%) were HIV-infected. As of January 2015, 95 (72.5%) were linked to HIV care, 90 (68.7%) were retained in HIV care, 80 (61.1%) were on cART, and 50 (38.2%) were virally suppressed one year after HIV diagnosis. Being non-white (Relative risk [lower bound; upper bound of 95% confidence interval] = 1.709 [1.145; 2.549]) and having a prior HIV-test (1.954 [1.278; 2.986]) were associated with an HIV-positive diagnosis. A higher linkage (2.603 [1.091; 6.211]) and retention in care (4.510 [1.880; 10.822]) were observed among those who were older than 30 years of age. Using community-based testing strategies, we were able to access a high-risk MSM population and a small sample of transwomen. Despite universal care coverage and the test-and-treat policy adopted in Brazil, the MSM cascade of care indicates that strategies to increase linkage to care and prompt cART initiation targeted to these populations are critically needed. Interventions targeting non-white and young MSM should be prioritized.

RESUMO

OBJECTIVES: HIV-infected women are at increased risk of human papillomavirus (HPV) infection. Time trends in annual prevalences of cervical high-risk human papillomavirus (HR-HPV) genotypes among a non-vaccinated, HIV-infected female cohort in urban Brazil were assessed for the period 2006-2012. METHODS: Cervical specimens were collected for HPV genotyping yearly between January 2006 and December 2012 in a cross-sectional analysis of participants aged ≥18 years enrolled in the Women's HIV Cohort at Fiocruz in Rio de Janeiro, Brazil. Age-adjusted generalized estimating equation models with an exchangeable matrix were used to estimate odds ratios (OR) and 95% confidence intervals (CI) for annual HPV positivity (reference year: 2006). RESULTS: Among the 590 participants, the median age across all study years ranged from 35.5 to 40.0 years. The prevalence of any HR-HPV was ≥53% every year; prevalences of HR-HPV 16, 58, 59, and 68 were ≥24% in at least 1 year. The odds of HPV 16 and 68 decreased in 2012. HPV 58 prevalence followed a U-shape, beginning and ending at >20%. HPV 59 prevalence followed a linear trend, with increased odds in 2012 (OR 16.0, 95% CI 3.8-67.3; Bonferroni-adjusted p-value <0.01). CONCLUSIONS: The prevalences of HR-HPV 58, 59, and 68 were high in this cohort. Given current HR-HPV vaccine coverage and availability, further investigations are needed to optimize vaccine recommendations for this population.

RESUMO

BACKGROUND: In Brazil, the rate of cervical cancer remains high despite the availability of screening programs. With ongoing vaccine development and implementation, information on the prevalence of specific HPV types is needed, particularly among high-risk populations, such as HIV-infected women. METHODS: We performed a study of HIV-infected women in Rio de Janeiro, Brazil, who underwent cervical HPV genotype testing between 2005-2013. We examined the prevalence of high-risk HPV types and the patterns of high-risk HPV type clustering. Using logarithmic binomial regression, we estimated the risk of abnormal cytology by HPV genotype result. RESULTS: Of the 562 women included, 498 (89 %) had at least one HPV type detected. 364 women (65 %) had at least one high-risk HPV type detected and 181 (32 %) had more than one high-risk type detected. HPV 58 was the most frequent HPV type detected overall (prevalence 19.8 % [95 % confidence interval 16.4-23.1]), followed by HPV 53 (prevalence 15.5 % [12.5-18.5]) and HPV 16 (prevalence 13 % [10.2-15.8]). Women infected with more than one high-risk HPV type were younger, had lower CD4+ lymphocyte counts, and were more likely to be infected with HPV 16 or 18. In adjusted analyses, presence of more than one high-risk HPV type was associated with a two-fold increased risk of abnormal cytology after adjusting for presence of individual high-risk type, age, and CD4+ lymphocyte count (adjusted prevalence ratios 1.88-2.07, all p <0.001). No single high-risk HPV type was statistically associated with abnormal cytology after adjusting for the presence of more than one high-risk HPV type. CONCLUSIONS: In the largest study of cervical HPV genotypes among HIV-infected women in Latin America, infection by high-risk HPV types other than 16 or 18 and infection by more than one high-risk HPV types were common. Infection by more than one high-risk type was more strongly associated with abnormal cervical cytology than any individual high-risk HPV type, highlighting the need for multi-valent HPV vaccines.

RESUMO

Identifying factors, including human papillomavirus (HPV) genotypes, associated with abnormal anal cytology in HIV-infected women have implications for anal squamous cell cancer (SCC) prevention in HIV-infected women. Anal and cervical samples were collected for cytology, and tested for high-(HR-HPV) and low-risk HPV (LR-HPV) genotypes in a cross-sectional analysis of the IPEC Women's HIV Cohort (Rio de Janeiro, Brazil). Multivariate log-binomial regression models estimated prevalence ratios for factors associated with abnormal anal cytology [≥ atypical squamous cells of undetermined significance, (ASC-US)]. Characteristics of the 863 participants included: median age 42 years, 57% non-white, 79% current CD4+ T-cell count >350 cells/mm(3), 53% HIV-1 viral load <50 copies/mL, median ART duration 5.8 years. Fifty-one percent of anal specimens contained ≥ 1 HR-HPV genotype; 31% had abnormal anal cytology [14% ASC-US, 11% low-grade squamous intra-epithelial lesion, (LSIL); 2% atypical squamous cells-cannot exclude high-grade SIL (ASC-H); 4% high-grade SIL/cancer (HSIL+)]. In multivariate analysis, cervical LSIL+, nadir CD4+ T-cell count ≤ 50 cells/mm(3), HIV-1 viral load ≥ 50 copies/mL, and anal HPV 6, 11, 16, 18, 33, 45, 52, 56, and 58 were associated with ≥ anal ASC-US (p<0.05). Abnormal anal cytology and HR-HPV prevalences were high. HIV-infected women with cervical LSIL+, low nadir CD4+ counts, or detectable HIV-1 viral loads should be a particular focus for enhanced anal SCC screening efforts.
