ABSTRACT Introduction: Effective and long-term combined antiretroviral therapy (cART) has decreased morbidity and mortality in HIV-infected individuals. Despite treatment advances, HIV-infected children continue to develop noninfectious conditions, including liver fibrosis. Methods: Cross-sectional study designed to identify liver fibrosis in HIV-infected adolescents and young adults, in an outpatients clinic of Pediatric Infectious Diseases Division at Escola Paulista de Medicina/Universidade Federal de São Paulo (UNIFESP), diagnosed by noninvasive methods (liver elastography–FibroScan®, APRI and FIB4). Variables examined included demographics, clinical, laboratories, HIV treatment. All participants underwent FibroScan® to measure liver parenchyma elasticity. Values equal to above 7.0 kPa were interpreted as the presence of significant liver fibrosis. Two different biomarkers of liver fibrosis were employed: the AST-to-Platelet Ratio Index (APRI) and the Fibrosis-4 score (FIB-4). APRI values above 1.5 have been considered as levels of clinically significant liver fibrosis and FIB-4 values above 3.25 suggested the presence of advanced fibrosis. Results: Between August 2014 and March 2017, the study enrolled 97 patients, age 10–27 years old, fourteen of 97 subjects (14.4%) presented liver stiffness (≥7 kPa) detected by the liver elastography. No patient had APRI> 1.5. No patient had FIB4 value > 3.25. The only isolated laboratory parameter that could be significantly associated with high liver stiffness was thrombocytopenia (p= 0.022, Fisher's exact test). Conclusion: Liver stiffness was identified in 14.4% (14/97) of this cohort by liver elastography. Liver disease in HIV-infected adolescents and young adults manifests itself silently, so should be routinely investigated.

RESUMO Objetivo: Identificar a percepção da importância das vacinas e os riscos da recusa vacinal entre alunos de Medicina e médicos. Métodos: Estudo transversal realizado por meio da aplicação de questionários sobre vacinas, recusa vacinal e suas repercussões acerca da saúde pública e individual. A amostra, de 92 sujeitos, foi selecionada numa escola privada de Medicina: grupo 1 (53 estudantes do primeiro ao quarto ano) e grupo 2 (39 médicos). Os dados colhidos foram tabulados no programa Microsoft Excel e analisados estatisticamente com o teste exato de Fisher. Resultados: Os dois grupos consideram o Programa Nacional de Imunizações confiável e reconhecem a importância das vacinas, mas 64,2% dos estudantes e 38,5% dos médicos desconhecem o número de doenças infecciosas evitáveis pelas vacinas no calendário básico. A maioria dos entrevistados possuía carteira de vacinas, mas nem todos receberam vacina influenza 2015. Conheciam pessoas que recusavam vacinas e/ou recusavam vacinar seus filhos (respectivamente, 54,7 e 43,3% dos estudantes e 59,0 e 41,0% dos médicos). Dos médicos, 48,7% já atenderam pacientes que se recusaram a receber vacinas. Consideram causas de recusa vacinal: medo de eventos adversos, razões filosóficas, religiosas e desconhecimento sobre gravidade e frequência das doenças. Aspectos éticos da recusa vacinal e possibilidades legais de exigir vacinas para crianças não são consenso. Conclusões: Alunos de Medicina e médicos não se vacinam adequadamente, apresentam dúvidas sobre calendário vacinal, segurança das vacinas e recusa vacinal. Melhorar sua capacitação é importante estratégia para manter as coberturas vacinais e abordar a recusa vacinal de forma ética.

ABSTRACT Objective: To identify the perception of medical students and physicians on the importance of vaccination and the risks of vaccine refusal. Methods: Cross-sectional study with application of questionnaires about vaccines, vaccine refusal and its repercussions on public and individual health. A sample of 92 subjects was selected from a private medical school: group 1 (53 students from first to fourth grades) and group 2 (39 physicians). Data collected were tabulated in the Microsoft Excel Program and analyzed by Fisher’s exact test. Results: Both groups considered the National Immunization Program reliable and recognized the importance of vaccines, but 64.2% of students and 38.5% of physicians are unaware of the vaccine-preventable infectious diseases in the basic immunization schedule. Most of the interviewees had a personal vaccine registry, but not all had received the 2015 influenza vaccine. Both groups had known people who refused vaccines for themselves or for their children (respectively, 54.7 and 43.3% of students and 59.0 and 41.0% of physicians). The total of 48.7% of physicians had already assisted vaccine refusers. Appointed causes of vaccine refusal were: fear of adverse events, philosophical and religious reasons and lack of knowledge about severity and frequency of diseases. Ethical aspects of vaccine refusal and legal possibilities of vaccine requirements for children are not consensus. Conclusions: Medical students and doctors are not adequately vaccinated and have queries about the vaccination schedule, vaccine safety and vaccine refusal. Improving these professionals’ knowledge is an important strategy to maintain vaccine coverage and address vaccine refusal ethically.

Resumo Objetivo: Oposição às vacinas não é evento novo e surgiu logo após a introdução da vacina contra varíola no fim do século XVIII. O objetivo desta revisão é esclarecer os profissionais de saúde sobre hesitação e recusa vacinal, suas causas e consequências e fazer sugestões para enfrentar esse desafio. Fonte dos dados: Foi feita busca abrangente e não sistemática nas bases de dados PubMed, Lilacs e Scielo desde 1980 até o presente, com os termos "recusa vacinal", "hesitação vacinal" e "confiança nas vacinas". Foram selecionadas de forma crítica as publicações avaliadas como mais relevantes pela autora. Síntese dos dados: As crenças e os argumentos dos movimentos antivacinas mantiveram-se inalterados nos dois últimos séculos, mas as novas mídias sociais facilitaram a disseminação das informações contra as vacinas. Os estudos sobre o assunto se intensificaram depois de 2010, mas não foram identificados estudos publicados que permitam quantificar esse comportamento no Brasil. A nomenclatura sobre o tema (hesitação vacinal) foi uniformizada pela Organização Mundial de Saúde em 2012. Pesquisas têm sido feitas sobre as possíveis causas da hesitação e recusa vacinal, e também sobre o comportamento das famílias e dos profissionais da saúde. Propostas de intervenções para diminuir as dúvidas da população, esclarecer mitos e melhorar a confiança nas vacinas têm sido feitas. Guias para o profissional de saúde enfrentar o problema estão surgindo. Conclusões: O profissional de saúde é elemento fundamental para transmitir informações, combater as dúvidas e fortalecer a confiança nas vacinas. Eles devem se preparar para enfrentar esse novo desafio.

Abstract Objective: Opposition to vaccines is not a new event, and appeared soon after the introduction of the smallpox vaccine in the late 18th century. The purpose of this review is to educate healthcare professionals about vaccine hesitancy and refusal, its causes and consequences, and make suggestions to address this challenge. Source of data: A comprehensive and non-systematic search was carried out in the PubMed, LILACS, and ScieLo databases from 1980 to the present day, using the terms "vaccine refusal," "vaccine hesitancy," and "vaccine confidence." The publications considered as the most relevant by the author were critically selected. Synthesis of data: The beliefs and arguments of the anti-vaccine movements have remained unchanged in the past two centuries, but new social media has facilitated the dissemination of information against vaccines. Studies on the subject have intensified after 2010, but the author did not retrieve any published studies to quantify this behavior in Brazil. The nomenclature on the subject (vaccine hesitancy) was standardized by the World Health Organization in 2012. Discussions have been carried out on the possible causes of vaccine hesitancy and refusal, as well as on the behavior of families and health professionals. Proposals for interventions to decrease public doubts, clarify myths, and improve confidence in vaccines have been made. Guides for the health care professional to face the problem are emerging. Conclusions: The healthcare professional is a key element to transmit information, resolve doubts and increase confidence in vaccines. They must be prepared to face this new challenge.

Resumo Resultados nulos, negativos ou inesperados são ocorrências possíveis para pesquisadores em todo o mundo. Não publicar tais resultados representa desperdício de recursos (de tempo, dinheiro e esforços). O objetivo deste estudo foi avaliar, mediante aplicação de questionário, o que estudantes de medicina e médicos pensam sobre a publicação de resultados inesperados ou negativos em pesquisa e discutir os aspectos éticos da questão. As questões foram respondidas por 40 alunos e 30 médicos de uma faculdade privada de medicina. Conclui-se que ainda é pouco discutida e aceita a publicação de resultados negativos ou inesperados, persistindo a crença que publicar tais resultados pode prejudicar a reputação dos pesquisadores. Quase todos os participantes acreditam ser importante a publicação desse tipo de resultados, mas apenas cerca de 60% os publicariam. Torna-se, então, importante e necessário ampliar a discussão sobre o assunto nas escolas médicas para se criar nova mentalidade acadêmica.

Abstract Null, negative or unexpected results are possible occurrences for researchers around the world. Not publishing such results is a waste of resources (time, money, and effort). The objective of this study was to evaluate, through a questionnaire, what medical students and physicians thought about the publication of unexpected or negative results in research and to discuss the ethical aspects of the matter. The questions were answered by 40 students and 30 physicians from a private medical school. It is concluded that the publication of negative or unexpected results is still insufficiently discussed and accepted, perpetuating the belief that publishing such results may harm the researchers’ reputation. Almost all participants believe it is important to publish these kind of results, but only about 60% of them would publish such results. It is therefore important and necessary to broaden the discussion on this subject in medical schools to create a new academic mindset.

ABSTRACT Background: The increase in life expectancy for patients living with human immunodeficiency virus (HIV) infection has resulted in health complications related to a chronic disease. Objectives: To evaluate the prevalence of bone mineral density (BMD) alterations and vitamin D concentrations in HIV-infected children and adolescents and to verify the variations in those parameters during a 12-month interval. Methods: A prospective cohort study with a dual period of evaluation was conducted in 57 patients perinatally HIV-infected and one patient with sexual abuse in early infancy. Demographic, anthropometric, pubertal stage, viral load, T CD4+ cell count and antiretroviral therapy were evaluated. Biochemical tests and total body (TB) and lumbar spine (L1-L4) bone density evaluations by dual X-ray absorptiometry (DXA) were performed. Calcium or vitamin D supplements were prescribed if reduction in BMD or deficiency for vitamin D was detected. Results: 58 patients (ages 5.4-18.3 years; 60.3% girls) were included (T0); 55 patients were reevaluated after 12 (±3) months (T1). Low bone mass for chronological age was found in 6/58 (10.4%) and 6/55(10.9%) patients at T0 and at T1, respectively. There was no statistical relationship between z-scores for BMD (BMD z-score) and the variables sex, fracture history, family history of osteoporosis, physical activity and pubertal stage. There was a relation between BMD z-score alterations for TB and HIV viral load at T1 (p = 0.016). There was no association between duration or classes of antiretroviral therapy and bone density. The mean value of vitamin D in T0 was 23.43 ng/mL ± 2.015 and in T1 22.1 ng/mL ± 0.707 and considered insufficient levels for this population. Conclusion: Patients infected with HIV are at risk for BMD alterations and lower vitamin D serum concentrations; both of these variables should be evaluated at routine examinations in order to improve both prevention and therapeutic planning.

RESUMO Diminuir as iniquidades na assistência à saúde continua sendo um grande desafio para países tanto pobres quanto ricos. No Brasil, o Programa Mais Médicos (PMM) foi instituído pelo governo federal em 2013 com a proposta de formar recursos humanos na área médica para o Sistema Único de Saúde (SUS), diminuir a carência de médicos, reduzir as desigualdades regionais na área da saúde e aprimorar a formação médica, ampliando a inserção do médico em formação nas áreas onde ele possa conhecer melhor a realidade da saúde da população. Considerando que os estudantes da área da saúde estão diretamente envolvidos com as propostas e os desfechos desse programa, o objetivo deste estudo foi avaliar o conhecimento e posicionamento não só dos estudantes, mas também de seus professores sobre o PMM. Um questionário foi aplicado a 106 alunos e 53 professores de uma faculdade privada na área da saúde (Medicina e Odontologia). A taxa de acerto das 25 questões sobre os objetivos e propostas de ação do PMM variou de 38,4% a 50,6%. A maioria dos docentes e alunos de Medicina referiu conhecer o PMM e reconhecia como proposta do programa diminuir a carência de médicos e melhorar a atuação nas políticas públicas de saúde. A proposta de aprimoramento da formação médica, oferta de cursos de Medicina e de vagas para residência médica, entretanto, era desconhecida por mais de 60% dos entrevistados. A contratação de médicos estrangeiros foi erroneamente considerada não só como um dos objetivos do programa, mas também como a ação proposta para atingir seus objetivos. Em conclusão, alunos e professores de instituições da área da saúde, embora sendo atores importantes na estratégia de atingir os objetivos propostos, conhecem pouco o PMM, particularmente nas ações relacionadas ao currículo das escolas e à residência médica. Estimular debates sobre o programa em escolas médicas pode modificar essa situação e favorecer o seu desfecho.

ABSTRACT Tackling unequal access to healthcare is a major challenge in both developed and developing countries. In Brazil, the Programa Mais Médicos (More Doctors Program – PMM) was created by the federal government in 2013 in order to reduce the shortage of doctors, address regional inequalities in healthcare access and improve medical education, expanding doctors’ training in fields where they can better understand the reality of the population’s health. Considering that students in the healthcare field are directly involved with the proposals and outcomes of this program, the objective of this study was to evaluate student knowledge and positioning and also that of their teachers on the PMM. A questionnaire was therefore administered to 106 students and 53 professors at a private medical and dentistry school. The hit rate for the 25 questions on the PMM’s objectives and proposals ranged from 38.4% to 50.6%.The majority recognized the PMM’s aim to reduce the shortage of doctors and improve public policies related to healthcare. The PMM’s aim to improve medical training, increasing the availability of medical courses and medical residencies, proved, however, to be unknown to over 60% of respondents. The hiring of foreign doctors was mistakenly considered not only to be the objective of the program, but also part of the initiatives designed to achieve the program objectives. The conclusion reached is that although university health sciences students and professors serve as important actors in the strategy for achieving the PMM’s goals, they have limited knowledge on the program, particularly in terms of the initiatives related to medical curricula and medical residencies. Discussion on the program could be introduced to medical courses in order to address this situation and improve the program’s outcomes.

Abstract The main objective of this work is to describe the formation of the Transition Adolescent Clinic (TAC) and understand the process of transitioning adolescents with HIV/AIDS from pediatric to adult care, from the vantage point of individuals subjected to this process. A qualitative method and an intentional sample selected by criteria were adopted for this investigation, which was conducted in São Paulo, Brazil. An in-depth semi-structured interview was conducted with sixteen HIV-infected adolescents who had been part of a transitioning protocol. Adolescents expressed the need for more time to become adapted in the transition process. Having grown up under the care of a team of health care providers made many participants have reluctance toward transitioning. Concerns in moving away from their pediatricians and feelings of disruption, abandonment, or rejection were mentioned. Participants also expressed confidence in the pediatric team. At the same time they showed interest in the new team and expected to have close relationships with them. They also ask to have previous contacts with the adult health care team before the transition. Their talks suggest that they require slightly more time, not the time measured in days or months, but the time measured by constitutive experiences capable of building an expectation of future. This study examines the way in which the adolescents feel, and help to transform the health care transition model used at a public university. Listening to the adolescents’ voices is crucial to a better understanding of their needs. They are those who can help the professionals reaching alternatives for a smooth and successful health care transition.

Resumo Objetivo: Explorar os significados atribuídos pelos jovens a "viver a adolescência com o HIV" em um grupo de pacientes que adquiriu a infecção ao nascimento e os elementos implicados na adesão ao tratamento antirretroviral. Métodos: Pesquisa de natureza qualitativa, com 20 sujeitos (13 a 20 anos), acompanhados em serviços especializados no tratamento da Aids pediátrica em São Paulo, Brasil. Foram feitas entrevistas semidirigidas cujo roteiro foi composto por questões sobre suas histórias pessoais, dificuldades e experiências que enfrentam diante da infecção pelo HIV/Aids. Resultados: Ser "normal" e "diferente" foram questões centrais no discurso dos participantes. Entretanto, a condição de uma vida normal é garantida mediante a responsabilidade com a saúde, a ressalva de que seja mantido o segredo do diagnóstico e as preocupações com a transmissão do vírus e divulgação do HIV ao parceiro sexual. As respostas sobre o tratamento apontam que a adesão é um processo dinâmico e envolve momentos de maior ou menor interesse em relação aos cuidados com a saúde. Os adolescentes têm planos e projetos e, apesar de o HIV ser considerado um agente estressor, prevaleceram perspectivas positivas diante do futuro. Conclusões: Viver a adolescência com o HIV envolve dimensões delicadas, que necessitam ser reconhecidas e legitimadas pelos profissionais que acompanham a trajetória desses jovens. Trata-se de possibilitar um espaço no qual o adolescente possa refletir e encontrar apoio para as questões relacionadas à construção de sua sexualidade e cuidados com seu próprio corpo.

Abstract Objective: Explore the meanings attributed by young individuals about "living as an adolescent with HIV" in a group of patients that acquired the infection at birth and the elements involved with the adherence to antiretroviral treatment. Methods: Qualitative study, involving 20 subjects (aged 13-20 years), followed at services specialized in the treatment of pediatric AIDS in São Paulo, Brazil. Semi-structured interviews were carried out of which script consisted of questions about their personal histories, experiences and difficulties they must face while living with HIV/AIDS. Results: Being "normal" and "different" were central issues voiced by the participants. However, a normal life situation is guaranteed by being responsible with one's health, the condition that the diagnosis be kept secret and concerns about HIV transmission and dissemination to a sexual partner. The answers about treatment show that adherence is a dynamic process and involves moments of greater or lesser interest in relation to care for one's health. The adolescents have plans and projects and although HIV is considered a stressor, positive perspectives for the future prevailed. Conclusions: To live as an adolescent with HIV involves subtle dimensions that need to be recognized and legitimized by professionals who follow the trajectory of these young individuals. It is necessary to allow a space in which the adolescents can reflect and find support regarding issues related to the construction of their sexuality and care of one's own body.

ABSTRACT OBJECTIVE: To evaluate bone mass accrual and determine the influence of clinical, anthropometric, dietary and biochemical parameters on bone mass. METHODS: A cohort study including 35 prepubertal HIV-infected children, between 7 and 12 years, attended at a referral center. At time 1 (T1) and time 2 (T2), patients were assessed according to clinical, anthropometric, dietary, biochemical parameters and bone mineral density (BMD). At T2, patients were divided into prepubertal and pubertal. RESULTS: Despite the increase in bone mass absolute values, there was no improvement in lumbar spine BMD (LSBMD) Z-score (p = 0.512) and worsening in total body BMD (TBMD) Z-score (p = 0.040). Pubertal patients (n = 19) showed higher bone mineral content (BMC) (p = 0.001), TBMD (p = 0.006) and LSBMD (p = 0.002) compared to prepubertal patients. After multivariate linear regression analysis, the predictors of bone mass in T1 were age, BMI and HAZ-scores for BMC; BMI Z-score, adequate serum magnesium concentration and dietary calcium intake for TBMD; adequate serum concentration of magnesium, BMI and HAZ-scores for LSBMD. In T2, age, total body fat and lean body mass (kg) for BMC; BMI Z-score and puberty for TBMD; dietary fat intake, BMI Z-score for BMD and puberty for LSBMD. CONCLUSION: HIV-infected children have compromised bone mass and the presence of puberty seems to provide suitability of these parameters. Adequate intake of calcium and fat appears to be protective for proper bone mass accumulation factor, as well as monitoring nutritional status and serum magnesium concentration.

OBJETIVO: Avaliar possíveis fatores associados à perda de anticorpos para o vírus da hepatite A (VHA) sete anos após a imunização primária e resposta à revacinação em crianças nascidas de mães soropositivas para HIV nos pacientes soronegativos para Hepatite A. MÉTODOS: Quantificação de anticorpos para o VHA por meio da eletroquimioluminescência foi feita em 39 adolescentes acompanhados no Ambulatório de Aids Pediátrica da Universidade Federal de São Paulo (Unifesp): 29 infectados pelo HIV e 10 expostos e não infectados (ENI) pelo HIV, com mediana de idade, respectivamente, de 12,8 e 13,4 anos. Todos receberam duas doses da vacina VHA (Havrix(r)) em 2002. RESULTADOS: A mediana da idade na época da imunização primária (IP) era de 5,4 anos para o grupo HIV e 6,5 anos para o grupo ENI. As crianças dos dois grupos apresentaram anticorpos para o VHA > 20 mUI/mL após a IP. Sete anos após, o grupo ENI apresentava mediana de anticorpos = 253,5 mUI/mL e o grupo HIV = 113,0 mUI/mL (Mann-Whitney; p=0,085). Todo grupo ENI e 23/29 (79,3%) do grupo HIV mantiveram anticorpos contra o VHA sete anos após IP. Os níveis de anticorpos para hepatite A na primovacinação foram o único fator independentemente associado à manutenção desses anticorpos decorridos sete anos. O grupo que perdeu soropositividade para VHA foi revacinado e 83,3% (5/6) responderam com anticorpos >20 mUI/mL. CONCLUSÕES: Os níveis de anticorpos obtidos na primovacinação no grupo HIV foram o principal fator associado à perda de anticorpos após imunização VHA

OBJECTIVE: To assess possible factors associated with the loss of antibodies to hepatitis A 7 years after the primary immunization in children of HIV-infected mothers and the response to revaccination in patients seronegative for hepatitis A. METHODS: Quantification of HAV antibodies by electrochemiluminescence was performed in 39 adolescents followed up at the Pediatric Aids Clinic of Federal University of São Paulo (Unifesp): 29 HIV-infected (HIV group) (median age: 12.8 years) and 10 HIV-exposed but non-infected (ENI group) (median age: 13.4 years). All of them received two doses of HAV vaccine (Havrix(r)) in 2002. RESULTS: The median age at primary immunization (PI) was 5.4 years for HIV group and 6.5 years for ENI group. All children, from both groups, had antibodies to HAV >20 mIU/mL after PI. Seven years later, the ENI group showed a median concentration of antibodies = 253.5 mIU/mL, while the HIV group = 113.0 mIU/mL (Mann-Whitney test, p=0.085). All ENI group and 23/29 (79.3%) from HIV group mantained HAV antibodies 7 years after PI. The levels of hepatitis A antibodies in the primary vaccination were the only factor independently associated with maintaining these antibodies for 7 years. The group that lost HAV seropositivity was revaccinated and 83.3% (5/6) responded with antibodies >20 mUI/mL. CONCLUSIONS: The antibodies levels acquired in the primary vaccination in the HIV group were the main factor associated with antibodies loss after HAV immunization.

OBJETIVO: Alertar o pediatra sobre a ocorrência de hipertensão portal não cirrótica (HPNC) na faixa etária pediátrica, no sentido de evitar as consequências catastróficas dessa doença, como o sangramento de varizes de esôfago. DESCRIÇÃO DO CASO: Paciente de 13 anos, infectado pelo HIV por via vertical, recebia esquema antirretroviral com didanosina (ddI) havia 12 anos. Apesar do controle adequado da replicação viral, com carga viral do HIV indetectável havia 12 anos, passou a apresentar diminuição gradativa dos linfócitos TCD4+, trombocitopenia prolongada e fosfatase alcalina elevada. O exame físico detectou esplenomegalia, que desencadeou o processo de investigação e culminou no diagnóstico de fibrose hepática acentuada pela elastografia, por provável toxicidade hepática devido ao uso prolongado de ddI. COMENTÁRIOS: Este é o primeiro caso de HPNC em adolescente infectado pelo HIV descrito no Brasil. Embora seja entidade mórbida rara em pacientes soropositivos para o HIV na faixa etária pediátrica, deve ser investigada nos pacientes em uso prolongado de ddI ou que apresentem indicadores clínicos e/ou laboratoriais de hipertensão portal, como esplenomegalia, trombocitopenia e aumento de fosfatase alcalina.

OBJECTIVE: To alert the pediatrician who is following up HIV-infected patients about the possibility of non-cirrhotic portal hypertension (NCPH) in this period of life, in order to avoid the catastrophic consequences of this disease as bleeding esophageal varices. CASE DESCRIPTION: A 13 years old HIV-infected patient by vertical route was receiving didanosine (ddI) for 12 years. Although the HIV viral load had been undetectable for 12 years, this patient showed gradual decrease of CD4+ T cells, prolonged thrombocytopenia and high alkaline phosphatase. Physical examination detected splenomegaly, which triggered the investigation that led to the diagnosis of severe liver fibrosis by transient elastography, probably due to hepatic toxicity by prolonged use of ddI. COMMENTS: This is the first case of NCPH in HIV-infected adolescent described in Brazil. Although, the NCPH is a rare disease entity in seropositive patients in the pediatric age group, it should be investigated in patients on long-term ddI or presenting clinical and laboratories indicators of portal hypertension, as splenomegaly, thrombocytopenia and increased alkaline phosphatase.

OBJETIVO: O objetivo deste estudo foi identificar possíveis entraves ao controle da transmissão vertical da sífilis e HIV através da análise do processo de encaminhamento das gestantes desde os serviços de atendimento pré-natal até o Centro Obstétrico de um hospital universitário, no município de São Paulo (referência), e seu retorno, com seus bebês expostos, após alta hospitalar, para acompanhamento (contrarreferência). MÉTODO: Estudo de corte transversal, retrospectivo, acrescido de entrevistas com profissionais de saúde. Gestantes com sífilis e/ou infecção pelo HIV foram identificadas na admissão para o parto de agosto de 2006 a agosto de 2007. A rotina e o fluxo dos encaminhamentos de mães e recém-nascidos foram analisados. RESULTADOS: Foram identificadas 56 gestantes infectadas: 43 com infecção pelo HIV, 11 com sífilis e duas coinfectadas (sífilis/HIV); 22 profissionais de saúde foram entrevistados. Acompanhamento pré-natal foi feito por 91,1% das mulheres: 7/11 (63,6%) com sífilis; 44/45 (97,8%) infectadas pelo HIV ou coinfectadas. A referência para o parto foi adequada para 57,1% das gestantes com sífilis e 97,7% daquelas infectadas pelo HIV. A contrarreferência foi adequada para todas as gestantes, apesar da não aderência a essa recomendação. Entrevistas com os profissionais de saúde revelaram que as rotinas e o fluxo de encaminhamento das gestantes, puérperas e recém-nascidos estão mais bem estabelecidos para HIV do que para sífilis. A vigilância epidemiológica e notificação também foram mais eficazes para o HIV. CONCLUSÃO: As dificuldades no sistema de referência e contrarreferência dessas mulheres e seus bebês são evidentes entraves ao controle da transmissão vertical desses agravos.

OBJECTIVE: The objective of this study was to identify possible barriers to control vertical transmission of syphilis and HIV through the analysis of the orientation process of pregnant women from prenatal care to the obstetric center at an university hospital in Sao Paulo (Reference) and their return (with their exposed babies) for follow-up after hospital discharge (counter-reference). METHODS: It is a retrospective cross-sectional study including interviews with healthcare personnel. Pregnant women with syphilis and/or HIV-infection admitted for labor or miscarriage were identified from August 2006 to August 2007. Routine care for mothers and babies were analyzed. RESULTS: 56 pregnant women were identified: 43 were HIV-infected, 11 had syphilis and two were coinfected (syphilis/HIV); 22 health care professionals were interviewed. Prenatal care was identified in 91.1% of these women: 7/11 (63.6%) with syphilis; 44/45 (97.8%) HIV-infected or coinfected. The reference for delivery was satisfactory for 57.7% of the syphilis-infected women and 97.7% of the HIV-infected ones. The counter-reference was satisfactory for all babies and mothers at hospital discharge, besides the non-adherence to this recommendation. Interviews with health care professionals showed there are better routines for assisting and following-up pregnant women, puerperal women and HIV-infected or exposed babies than for those infected with syphilis. The epidemiological report and surveillance system are also better for HIV-infected patients. CONCLUSION: The difficulties in the reference and counter-reference system of these women and their babies are evident barriers to control the vertical transmission of these infectious diseases.

The reference for delivery was satisfactory for 57.7% of the syphilis-infected women and 97.7% of the HIV-infected ones. The counter-reference was satisfactory for all babies and mothers at hospital discharge, besides the non-adherence to this recommendation. Interviews with health care professionals showed there are better routines for assisting and following-up pregnant women, puerperal women and HIV-infected or exposed babies than for those infected with syphilis. The epidemiological report and surveillance system are also better for HIV-infected patients. CONCLUSION: The difficulties in the reference and counter-reference system of these women and their babies are evident barriers to control the vertical transmission of these infectious diseases.

Objective:This study aims to assess the nutritional status of selenium, copper and zinc; and also the erythrocyte superoxide dismutase activity of HIV-infected children compared to a control group.Methods:A cross-sectional study was carried out with prepubertal HIV-infected children (n = 51) and their healthy siblings (n = 32). All biochemical measurements including plasma selenium, serum copper levels, serum and erythrocyte zinc levels and erythrocyte super-oxide dismutase activity were evaluated according to dietary, clinical and biochemical parameters.Results:Compared to the control group, the HIV-infected children had lower z-score values for height-for-age (p = 0.0006), higher prevalence of stunting (11.8%) (p = 0.047), lower selenium levels (p = 0.0006) and higher copper levels (p = 0.019). No difference was found concerning superoxide dismutase activity (p > 0.05). The HIV-infected group presented a higher proportion (45.1%) of children with zinc intakes below the estimated average requirement (p = 0.014); however, no association with zinc biochemical parameters was found.Conclusion:HIV-infected children have an inadequate selenium and copper nutritional status, which could influence the progression to AIDS. An adequate micronutrient status could improve the clinical conditions in these patients and minimize free radical production and cellular oxidative stress.

Trata-se de um relato de experiência sobre a condução e manejo do processo de revelação diagnóstica em crianças vivendo com o HIV/Aids, em dois centros de referência localizados no município de São Paulo, Brasil. O modelo utilizado para compartilhar as informações sobre a doença e tratamento à população pediátrica foi iniciado no ano de 2003 e envolve 5 etapas: captação dos pacientes desconhecedores de sua condição sorológica; encaminhamento para avaliação psicológica; entrevistas com os familiares para o planejamento do processo de revelação; abertura diagnóstica e acompanhamento pós-revelação. A experiência tem demonstrado que após o conhecimento da doença as crianças participam e colaboram com o tratamento, os pais sentem-se aliviados e os profissionais ficam à vontade, durante as consultas, para conversarem abertamente com os pequenos pacientes sobre os exames, acompanhamento clínico e tratamento. A descrição detalhada do trabalho desenvolvido poderá auxiliar outros serviços no desenvolvimento de ações para que a prática da revelação diagnóstica possa ser integrada de forma mais efetiva no contexto do cuidado das crianças que vivem com o HIV/Aids.

This is an experience report on the conduct and management of the process of revealing the diagnosis of children living with HIV/AIDS in two leading centers located in São Paulo, Brazil. The model used to share information about the disease and treatment in the pediatric population was initiated in 2003 and involves 5 steps: gathering patients unaware of their HIV status; referrals for psychological assessment; interviews with family members to plan the disclosure process; open diagnostic and monitoring after the disclosure. Experience has shown that after knowledge of the disease, the children participate and cooperate with treatment, parents feel relieved and professionals are comfortable during consults, to talk openly with young patients about the exams, clinical monitoring and treatment. A detailed description of the work may assist other services in developing actions so that the practice of diagnostic disclosure can be more effectively integrated in the context of the care of children living with HIV/AIDS.
