Treatment dropout after pregnancy: a study of women living with HIV in Rio de Janeiro.

Despite the investment in prevention of mother-to-child transmission of HIV, there is still little data about the proportion of women that are retained in treatment after pregnancy in Brazil. Research worldwide shows that a significant proportion of women drop out of treatment after pregnancy. The aim of this study was to identify factors associated with treatment dropout of women that received prenatal care at a federal hospital in Rio de Janeiro between 2016 and 2017 and abandoned treatment after pregnancy. This was a retrospective cohort study using data on prescription refills and hospital medical records. Cross-sectional analysis of data from 454 women showed that 18% were not on cART after pregnancy. Illicit drug use during pregnancy, being less than 35 years old, and being aware of HIV diagnosis before conceiving but not taking cART were factors associated with treatment interruption postpartum. The high prevalence of interruption of HIV treatment after pregnancy suggests that there is a need for better post-natal care to increase adherence in this population.

Retrospective analysis of risk factors and gaps in prevention strategies for mother-to-child HIV transmission in Rio de Janeiro, Brazil.

BACKGROUND: Despite great progress made in methods to prevent mother-to-child transmission of HIV (MTCT), delivery and uptake of these measures remains a challenge in many countries. Although the Brazilian Ministry of Health aimed to eliminate MTCT by 2015, infection still occured in 15-24% of infants born to HIV-infected mothers. We sought to identify remaining factors that constrain MTCT elimination. METHODS: We conducted a retrospective, matched case-control study by reviewing hospital charts of infants born to HIV-infected mothers between 1997 and 2014 at three MTCT reference hospitals in the Rio de Janeiro metropolitan area. Cases were defined as HIV-exposed children with two positive HIV tests before 18 months of age; controls were defined as HIV-exposed children with two negative HIV tests before 18 months of age. We performed bivariate and MTCT cascade analyses to identify risk factors for MTCT and gaps in prevention services. RESULTS: We included 435 infants and their mothers (145 cases, 290 controls). Bivariate analyses of MTCT preventative care (PMTCT) indicated that cases were less likely to complete all individual measures in the antenatal, delivery, and postnatal period (p < 0.05). Assessing completion of the PMTCT cascade, the sequential steps of PMTCT interventions, we found inadequate retention in care among both cases and controls, and cases were significantly less likely than controls to continue receiving care throughout the cascade (p < 0.05). Motives for incompletion of PMTCT measures included infrastructural issues, such as HIV test results not being returned, but were most often due to lack of care-seeking. Over the course of the study period, PMTCT completion improved, although it remained below the 95% target for antenatal care, HIV testing, and antenatal ART set by the WHO. Adding concern, evaluation of co-infections indicated that case infants were also more likely to have congenital syphilis (OR: 4.29; 95% CI: 1.66 to 11.11). CONCLUSIONS: While PMTCT coverage has improved over the years, completion of services remains insufficient. Along with interventions to promote care-seeking behaviour, increased infrastructural support for PMTCT services is needed to meet the HIV MTCT elimination goal in Brazil as well as address rising national rates of congenital syphilis.

The "moral career" of perinatally HIV-infected children: revisiting Goffman's concept.

HIV-infected children usually live in vulnerable situations, experiencing discrimination and stigma commonly felt by other people living with HIV/AIDS. The present study aims to analyse primary socialisation of HIV-infected children and adolescents recruited from a public health service in Rio de Janeiro (Brazil) as a social process that shapes a new generation of stigmatised and vulnerable persons. Research was informed by an interactionist perspective, focusing on key aspects of HIV-infected children and adolescents life histories under the conceptual frame of Erving Goffman's theories regarding "moral careers". Goffman defines the making of a moral career as the process through which a person learns that she/he possesses a particular attribute, which may lead her/him to be discredited by members of the surrounding society. We have identified aspects of life histories of HIV-vertically infected children and adolescents for each aspect of "moral career" as described by Goffman, relating them to as family structure, the experience of living HIV within the family, and the position and family role of a given subject. The patterns of "moral career" proposed by Goffman in 1963 were useful in identifying components of HIV-related stigma among children and adolescents. These include gender and social disadvantages, difficulty in coping with a child with a potentially severe disease, orphanhood, abandonment, adoption and disclosure of one's HIV serostatus. Primary socialisation of HIV-infected children and adolescents is a key piece of the complex HIV/AIDS-labelling process that could be targeted by interventions aiming to decrease stigma and marginalisation. Health care workers and stakeholders should be committed to ensuring education and guaranteeing the legal rights of this specific population, including the continuous provision of quality health care, full access to school and support to full disclosure of HIV diagnosis.

HIV-related stigma among young people living with HIV transitioning to an adult clinic in a public hospital in Rio de Janeiro, Brazil. / Estigma relacionado ao HIV entre jovens em transição para a clínica de adultos num hospital público no Rio de Janeiro, Brasil.

This study analyzes how experiences of HIV-related stigma are expressed among HIV-positive young people transitioning to an adult clinic, the health service, the family, the affective-sexual interactions, and their relationship with inequalities and social hierarchies. This research included 31 young people (median age 21) transitioning to an adult clinic (G1) and 12 young people (median age 30) who had already made this transition (G2), both monitored at a health service in Rio de Janeiro. Seventy percent of the 43 young people were women and 65% were infected by mother-to-child transmission. Young people answered questionnaires and participated in focus groups on AIDS stigma and transition to adulthood. Most reported discrimination associated with HIV stigma in daily life and health care. G1 young people showed more significant concern about the consequences of HIV disclosure and difficulties with treatment. The G2 accounts suggest that establishing marital relationships, including HIV-negative partners and children, linked to treatment access allowed resignifying the fear of stigmatization. The findings aim to guide the training and action of professionals involved in the prevention and care of young people living with HIV.

Neste estudo investigamos como vivências de estigma do HIV se expressam entre jovens soropositivos, em transição para a clínica de adultos, no serviço de saúde, na família e nas interações afetivos-sexuais e sua relação com as desigualdades e hierarquias sociais. O estudo envolveu 31 jovens (idade mediana 21) em transição para a clínica de adultos (G1) e 12 jovens (idade mediana 30) que já fizeram essa transição (G2), ambos atendidos num serviço de saúde do Rio de Janeiro. Dentre os 43 jovens, 70% eram mulheres e 65% foi infectado por transmissão vertical. Os jovens responderam a questionários e participaram de grupos focais sobre estigma da aids e passagem para a vida adulta. A maioria relatou situações de discriminação associadas ao estigma do HIV na vida cotidiana e no cuidado em saúde. Os jovens do G1 revelaram maior preocupação com as consequências da revelação do HIV e dificuldades com o tratamento. Os relatos do G2 sugerem que a constituição de relações conjugais, incluindo parceiro/a e filhos soronegativos e o acesso ao tratamento, possibilitaram resignificar o receio da estigmatização. Os achados visam orientar a formação e ação de profissionais envolvidos na prevenção e cuidado de jovens vivendo com HIV.

Diagnosis of pulmonary tuberculosis in children and adolescents: comparison of two versions of the Brazilian Ministry of Health scoring system.

The aim of this study was to evaluate the concordance between two versions of the scoring system (2011 and 2019), recommended by the Brazilian Ministry of Health, for the diagnosis of pulmonary tuberculosis (PTB) in children and adolescents. A retrospective descriptive study was performed to assess the medical records of children and adolescents with PTB, in TB units from Brazilian cities located in Rio de Janeiro, Minas Gerais, and Parana States, from January 1 st , 2004, to December 1 st , 2018. Patients aged 0 to 18 years old with a diagnosis of PTB were included. The comparison between the two scoring systems showed a moderate concordance according to the κ coefficient value = 0.625. Fourteen patients showed a reduction in the TB score, going from 30 points in the 2011, to 25 points or less in the 2019 one. Seventy one percent of these 14 patients had radiological changes suggestive of PTB and 86% had tuberculin skin tests greater than 10 mm. The study concluded that a moderate agreement was observed between the 2011 and 2019 scoring systems, with an increase in the number of patients scoring 25 points or less in 2019, which can eventually hinder the diagnosis of PTB.

Randomized controlled trial of feeding a concentrated formula to infants born to women infected by human immunodeficiency virus.

OBJECTIVE: We tested the hypothesis that concentrated formula (CF) begun within the first 2 weeks of life increases growth in infants born to human immunodeficiency virus (HIV)-infected mothers. MATERIALS AND METHODS: HIV-exposed infants from the United States, the Bahamas, and Brazil were randomized in a double-blind, controlled trial to receive either a CF (87 kcal/100 mL [26 kcal/oz]) or a standard formula (SF; 67 kcal/100 mL [20 kcal/oz]) for 8 weeks. This article presents results for infants who were not determined to be HIV infected based on testing at 4 weeks. Primary outcomes were safety, tolerability, and growth in weight and length. RESULTS: Two thousand ninety-seven infants were enrolled, of whom 1998 were uninfected and had study formula dispensed. At weeks 4 and 8, uninfected infants receiving CF showed higher energy intake than those who were receiving SF (P < 0.001). By week 8, uninfected infants assigned to CF weighed more than infants receiving SF. There were no consistent differences in measures of tolerability, and rates of discontinuation or perceived formula intolerance were similar between treatment groups. CONCLUSIONS: A CF is well tolerated and results in increased weight gain compared with SF. Until the HIV status of an infant is reliably determined, early introduction of a CF in HIV-exposed children may have beneficial effects on growth. The role of early nutritional intervention remains to be determined for individuals living in countries with endemic malnutrition for whom formula feeding is a viable option.

Congenital toxoplasmosis infection in an infant born to an HIV-1-infected mother.

We report the occurrence of congenital toxoplasmosis in an infant born to an HIV infected mother who had high anti-toxoplasma IgG and negative IgM at nine weeks of gestation. We briefly review available literature and discuss the possible mechanisms of transmission of congenital toxoplasmosis among HIV infected pregnant women.

Adolescents with HIV and transition to adult care in the Caribbean, Central America and South America, Eastern Europe and Asia and Pacific regions.

INTRODUCTION: The HIV epidemics in the Caribbean, Central America and South America (CCASA), Eastern Europe (EE) and Asia and Pacific (AP) regions are diverse epidemics affecting different key populations in predominantly middle-income countries. This narrative review describes the populations of HIV-positive youth approaching adolescence and adulthood in CCASA, EE and AP, what is known of their outcomes in paediatric and adult care to date, ongoing research efforts and future research priorities. METHODS: We searched PubMed and abstracts from recent conferences and workshops using keywords including HIV, transition and adolescents, to identify published data on transition outcomes in CCASA, EE and AP. We also searched within our regional clinical/research networks for work conducted in this area and presented at local or national meetings. To give insight into future research priorities, we describe published data on characteristics and health status of young people as they approach age of transition, as a key determinant of health in early adulthood, and information available on current transition processes. RESULTS AND DISCUSSION: The perinatally HIV-infected populations in these three regions face a range of challenges including parental death and loss of family support; HIV-related stigma and socio-economic disparities; exposure to maternal injecting drug use; and late disclosure of HIV status. Behaviourally HIV-infected youth often belong to marginalized sub-groups, with particular challenges accessing services and care. Differences between and within countries in characteristics of HIV-positive youth and models of care need to be considered in comparisons of outcomes in young adulthood. The very little data published to date on transition outcomes across these three regions highlight some emerging issues around adherence, virological failure and loss to follow-up, alongside examples of programmes which have successfully supported adolescents to remain engaged with services and virologically suppressed. CONCLUSIONS: Limited data available indicate uneven outcomes in paediatric services and some shared challenges for adolescent transition including retention in care and adherence. The impact of issues specific to low prevalence, concentrated epidemic settings are poorly understood to date. Outcome data are urgently needed to guide management strategies and advocate for service provision in these regions.

Children and Adolescents with Perinatal HIV-1 Infection: Factors Associated with Adherence to Treatment in the Brazilian Context.

Challenges to the adherence to combination antiretroviral therapy among the pediatric population should be understood in the context of the trajectories of families, their interaction with healthcare services, and their access to material and symbolic goods. The present study analyzed individual, institutional and social factors that might be associated with the caregivers' role in the treatment adherence of children and adolescents living with HIV (CALHIV). Based on semi-structured interviews and questionnaires applied to 69 caregivers seen at pediatric AIDS services of five Brazilian macro-regions, we observed that adherent caregivers had better acceptance of diagnosis and treatment, were less likely to face discrimination and social isolation secondary to AIDS-related stigma and tended to believe in the efficacy of treatment, and to be more optimistic about life perspectives of CALHIV. Interventions aiming to improve adherence and to promote the health of CALHIV should take in consideration the interplay of such different factors.

Relationship between viral load and behavioral measures of adherence to antiretroviral therapy in children living with human immunodeficiency virus in Latin America.

Few studies have examined antiretroviral therapy adherence in Latin American children. Standardized behavioral measures were applied to a large cohort of human immunodeficiency virus-infected children in Brazil, Mexico, and Peru to assess adherence to prescribed antiretroviral therapy doses during the three days prior to study visits, assess timing of last missed dose, and evaluate the ability of the adherence measures to predict viral suppression. Time trends in adherence were modeled using a generalized estimating equations approach to account for possible correlations in outcomes measured repeatedly in the same participants. Associations of adherence with human immunodeficiency virus viral load were examined using linear regression. Mean enrollment age of the 380 participants was 5 years; 57.6% had undetectable' viral load (<400 copies/mL). At enrollment, 90.8% of participants were perfectly (100%) adherent, compared to 87.6% at the 6-month and 92.0% at the 12-month visit; the proportion with perfect adherence did not differ over time (p=0.1). Perfect adherence was associated with a higher probability of undetectable viral load at the 12-month visit (odds ratio=4.1, 95% confidence interval: 1.8-9.1; p<0.001), but not at enrollment or the 6-month visit (p>0.3). Last time missed any antiretroviral therapy dose was reported as "never" for 52.0% at enrollment, increasing to 60.7% and 65.9% at the 6- and 12-month visits, respectively (p<0.001 for test of trend). The proportion with undetectable viral load was higher among those who never missed a dose at enrollment and the 12-month visit (p≤0.005), but not at the 6-month visit (p=0.2). While antiretroviral therapy adherence measures utilized in this study showed some association with viral load for these Latin American children, they may not be adequate for reliably identifying non-adherence and consequently children at risk for viral resistance. Other strategies are needed to improve the evaluation of adherence in this population.

Normal Growth of Healthy Infants Born from HIV+ Mothers Fed a Reduced Protein Infant Formula Containing the Prebiotics Galacto-Oligosaccharides and Fructo-Oligosaccharides: A Randomized Controlled Trial.

OBJECTIVE: The aim of the current study was to evaluate the safety of a new reduced protein (2.1 g/100 kcal) infant formula containing 4 g/L of 90% galacto-oligosaccharides (GOS) and 10% fructo-oligosaccharides (FOS). METHODS: Healthy term infants from Brazil were enrolled. Those born to human immunodeficiency virus (HIV)-positive mothers were randomized to a test (n = 65) or control (n = 63) formula group. Infants born to HIV-negative mothers were either exclusively breast-fed (n = 79) or received a mixed diet (breast milk and test formula, n = 65). Between 2 weeks and 4 months of age, infants were exclusively fed according to their assigned group. Anthropometric measurements were taken at baseline, 1, 2, 3, 4, 6, 8, 10, and 12 months. Digestive tolerance was evaluated during the first 4 months. The primary outcome was mean daily weight gain between 2 weeks and 4 months in the test formula and breast-fed groups. RESULTS: Data from all infants (N = 272) were used in the intention-to-treat (ITT) analysis and data from 230 infants were used in the per-protocol (PP) analysis. The difference in mean daily weight gain between 2 weeks and 4 months in the test formula and breast-fed groups was 1.257 g/day (one-sided 95% confidence interval [CI]: -0.705 to inf, P < 0.001) in the PP analysis, showing that the lower bound of the 95% CI was above the -3.0 g/day non-inferiority margin. Results were similar in the ITT analysis. Symptoms of digestive tolerance and frequency of adverse events were similar in the two groups. CONCLUSIONS: The formula containing 2.1 g/100 kcal protein and GOS and FOS was safe and tolerated well.

Prevalence and predictors of elevated aspartate aminotransferase-to-platelet ratio index in Latin American perinatally HIV-infected children.

BACKGROUND: Chronic liver disease has emerged as an important problem in adults with longstanding HIV infection, but data are lacking for children. We characterized elevated aspartate aminotransferase-to-platelet ratio index (APRI), a marker of possible liver fibrosis, in perinatally HIV-infected children. METHODS: The National Institute of Child Health and Human Development International Site Development Initiative enrolled HIV-infected children (ages 0.1-20.1 years) from 5 Latin American countries in an observational cohort from 2002 to 2009. Twice yearly visits included medical history, physical examination and laboratory evaluations. The prevalence (95% confidence interval) of APRI > 1.5 was calculated, and associations with demographic, HIV-related and liver-related variables were investigated in bivariate analyses. RESULTS: APRI was available for 1012 of 1032 children. APRI was >1.5 in 32 (3.2%, 95% confidence interval: 2.2%-4.4%) including 2 of 4 participants with hepatitis B virus infection. Factors significantly associated with APRI > 1.5 (P < 0.01 compared with APRI ≤ 1.5) included country, younger age, past or current hepatitis B virus, higher alanine aminotransferase, lower total cholesterol, higher log10 current viral load, lower current CD4 count, lower nadir CD4 count, use of hepatotoxic nonantiretroviral (ARV) medications and no prior ARV use. Rates of APRI > 1.5 varied significantly by current ARV regimen (P = 0.0002), from 8.0% for no ARV to 3.2% for non-protease inhibitor regimens to 1.5% for protease inhibitor-based regimens. CONCLUSIONS: Elevated APRI occurred in approximately 3% of perinatally HIV-infected children. Protease inhibitor-based ARVs appeared protective whereas inadequate HIV control appeared to increase risk of elevated APRI. Additional investigations are needed to better assess potential subclinical, chronic liver disease in HIV-infected children.

Vitamin A, vitamin E, iron and zinc status in a cohort of HIV-infected mothers and their uninfected infants.

UNLABELLED: Introduction: We hypothesized that nutritional deficiency would be common in a cohort of postpartum, human immunodeficiency virus (HIV)-infected women and their infants. METHODS: Weight and height, as well as blood concentrations of retinol, α-tocopherol, ferritin, hemoglobin, and zinc, were measured in mothers after delivery and in their infants at birth and at 6-12 weeks and six months of age. Retinol and α-tocopherol levels were quantified by high performance liquid chromatography, and zinc levels were measured by atomic absorption spectrophotometry. The maternal body mass index during pregnancy was adjusted for gestational age (adjBMI). RESULTS: Among the 97 women 19.6% were underweight. Laboratory abnormalities were most frequently observed for the hemoglobin (46.4%), zinc (41.1%), retinol (12.5%) and ferritin (6.5%) levels. Five percent of the women had mean corpuscular hemoglobin concentrations < 31g/dL. The most common deficiency in the infants was α-tocopherol (81%) at birth; however, only 18.5% of infants had deficient levels at six months of age. Large percentages of infants had zinc (36.8%) and retinol (29.5%) deficiencies at birth; however, these percentages decreased to 17.5% and 18.5%, respectively, by six months of age. No associations between infant micronutrient deficiencies and either the maternal adjBMI category or maternal micronutrient deficiencies were found. CONCLUSIONS: Micronutrient deficiencies were common in HIV-infected women and their infants. Micronutrient deficiencies were less prevalent in the infants at six months of age. Neither underweight women nor their infants at birth were at increased risk for micronutrient deficiencies.

Crianças e adolescentes vivendo com HIV em acompanhamento em serviços brasileiros: análise dos fatores de vulnerabilidade na adesão ao tratamento antirretroviral / Children and adolescents living with HIV of services in Brazil: analysis of vulnerability factors in adherence to antiretroviral treatment

Este estudo analisa fatores associados à adesão ao tratamento antirretroviral entre crianças e adolescentes que adquiriram HIV a partir da infecção materna e em acompanhamento em serviços de referência localizados nas cinco macrorregiões do Brasil. Por meio de estratégias quantitativas e qualitativas foram investigados: o momento da descoberta do diagnóstico, o histórico do acesso aos serviços de saúde e da adesão ao tratamento e o contexto social e familiar de 260 crianças e adolescentes vivendo com HIV (CAVHIV) e de seus cuidadores. A adesão foi aferida com o auxílio de um indicador biológico (supressão viral evidenciada pela carga viral sanguínea) e um indicador comportamental (questionário de adesão). Foram realizadas entrevistas semi-estruturadas com os cuidadores e, em um dos serviços, foram registradas em um diário de campo histórias de crianças em acompanhamento e conteúdos de reuniões de equipe multiprofissional para a discussão dos casos com maior dificuldade de adesão. Os resultados foram apresentados em três artigos. O primeiro, focado na análise dos dados quantitativos, revelou que os cuidadores sem abuso de álcool/outras drogas (...) O segundo artigo analisa as implicações do momento da revelação do diagnostico para CAVHIV a partir da aplicação da teoria de Erving Goffman sobre estigma ao conteúdo do diário de campo; tal reflexão resultou na identificação de padrões de socialização de crianças vivendo com HIV e possíveis estratégias para diminuição de seu impacto em futuras gerações. No terceiro artigo foi feita a triangulação dos dados quantitativos e qualitativos, a partir do referencial de vulnerabilidade, visando a caracterização dos fatores de natureza individual, institucional e social que determinam o papel dos cuidadores na adesão de CAVHA à terapia antirretroviral combinada (TARVc)...

This study analyzes factors associated with adherence to antiretroviral treatment among perinatally HIV-infected children and adolescents (PHIV), under follow-up in pediatric sites located in the five geographical regions of Brazil. Through quantitative and qualitative strategies were investigated: the time of HIV diagnosis, the history of access to health services and treatment adherence and the social and family context of 260 children and adolescents living with HIV and its caregivers. Adherence was measured with the aid of a biological indicator (viral suppression verified by blood viral load) and a behavioral indicator (adherence scale). Caregivers were submitted to semi-structured interviews and in one of the services, stories of children and multidisciplinary team meetings to discuss cases with greater difficulty of adherence were recorded in a field diary. The results were presented in three articles. The first, focused on the quantitative analysis revealed that caregivers without alcohol / other drugs abuse (...) The second article analyzes, within the framework of Erving Goffman´s theory about stigma, the implications of the time of diagnosis disclosure to PHIV to the content of the field diary; this approach resulted in the identification of patterns of socialization of children living with HIV and possible strategies to decrease its impact on future generations. In the third article we searched for the triangulation of quantitative and qualitative results within the framework of vulnerability, aiming to characterize the individual, institutional and social nature factors that determine the role of caregivers in adherence of PHIV to combined antiretroviral therapy (cART)...

Congenital toxoplasmosis infection in an infant born to an HIV-1-infected mother

We report the occurrence of congenital toxoplasmosis in an infant born to an HIV infected mother who had high anti-toxoplasma IgG and negative IgM at nine weeks of gestation. We briefly review available literature and discuss the possible mechanisms of transmission of congenital toxoplasmosis among HIV infected pregnant women.

Trends in a Cohort of HIV-infected pregnant women in Rio de Janeiro, 1996-2004

OBJECTIVE: To describe trends in sociodemographic, immunological and virological profiles and interventions to decrease the risk of mother-to-child HIV transmission. METHODS: Retrospective cohort study conducted at a tertiary institution in Rio de Janeiro, Brazil from January 1996 to December 2004. Analysis was performed by stratification in three time periods: 1996-1998 (P1), 1999-2001 (P2) and 2002-2004 (P3). RESULTS: In 9 years, 622 pregnancies occurred. Complications included: maternal mortality 0.3 percent, stillbirths 2.5 percent, miscarriages 0.6 percent, neonatal mortality 1.1 percent, prematurity 9.9 percent, low birth weight (LBW) 16.5 percent, congenital malformations 2.2 percent. The number of HIV-infected pregnant patients grew threefold over time reflecting increased prevalence of disease and patient identification. HIV diagnosis before pregnancy increased from 30 percent in P1 to 45 percent in P3. The proportion of pregnant women receiving highly active antiretroviral therapy increased from none (P1) to 88 percent (P3) with a significant trend towards women delivering at undetectable viral loads in later years despite a higher frequency of advanced disease. Scheduled cesarean deliveries increased from 35 percent in P1 to 48 percent in P3. Perinatal transmission rates were 2.4 percent with a decline from 3.5 percent in P1 to 1.6 percent in P3. Neonatal outcomes tended to remain constant or improve with time. A slight rise in LBW and congenital malformations were observed. CONCLUSIONS: During the observational period, HIV+ pregnant women presented with more advanced disease and lower socio-economic status. However, improved management of HIV-infected patients (associated with increased identification and increased availability of treatment) resulted into very low transmission rates similar to those of developed countries with overall improvement of patient outcomes.

MÉTODOS: Estudo de coorte retrospectivo em uma instituição de saúde terciária no Rio de Janeiro de janeiro de 1996 a dezembro de 2004. A análise utilizou a estratificação em três períodos de tempo: 1996-1998 (P1), 1999-2001 (P2) e 2002-2004 (P3). RESULTADOS: Em 9 anos, 622 gestações foram acompanhadas. As complicações foram: mortalidade materna 0,3 por cento, natimortos 2,5 por cento, abortos 0,6 por cento, mortalidade neonatal 1,1 por cento, prematuridade 9,9 por cento, baixo peso ao nascer (BPN) 16,5 por cento, malformações congênitas 2,2 por cento. O número de gestantes HIV positivo triplicou ao longo do tempo, refletindo o aumento da prevalência da doença e a melhor identificação das pacientes. O diagnóstico da infecção pelo HIV antes da gestação aumentou de 30 por cento em P1 para 45 por cento em P3. A proporção de gestantes recebendo o tratamento combinado potente aumentou de zero em P1 para 88 por cento em P3 com uma tendência significativa a ter uma carga viral abaixo do limite de detecção no parto nos últimos anos apesar de uma maior proporção de pacientes com doença mais avançada. O índice de cesarianas eletivas aumentou de 35 por cento em P1 para 48 por cento em P3. A taxa de transmissão perinatal global foi de 2,4 por cento caindo de 3,5 por cento em P1 para 1,6 por cento em P3. Os desfechos neonatais tenderam a permanecer constantes ou a melhorar ao longo do tempo. Um discreto aumento dos índices de BPN e de malformações congênitas foi observado. CONCLUSÕES: Ao longo do período de estudo aumentou a proporção de gestantes HIV positivo com doença mais avançada e com padrão socioeconômico mais baixo. Por outro lado, a melhora da abordagem terapêutica dos pacientes infectados pelo HIV, associada a uma maior detecção de casos e maior acesso...
