Association between different treatment timings and adverse neonatal outcomes in pregnant women with syphilis during pregnancy / 中华预防医学杂志

Objective: To analyze the association between different treatment timings and adverse neonatal outcomes (premature birth, death, congenital syphilis) in syphilis-infected pregnant women. Methods: The National Management Information System for Prevention of HIV, Syphilis and HBV Mother-to-Child Transmission was used to collect information on the detection and treatment of syphilis-infected pregnant women and their newborns in Guangdong Province from October 2011 to December 2021. According to the gestational weeks of syphilis-infected pregnant women receiving penicillin treatment for the first time, they were divided into four groups: treatment in the first trimester, treatment in the second trimester, treatment in the third trimester, and no treatment during pregnancy. Multivariate logistic regression was used to analyze the association between different treatment timings and adverse neonatal outcomes in syphilis-infected pregnant women. Results: A total of 22 483 syphilis-infected pregnant women were included. The number of pregnant women who started treatment in the first trimester, second trimester, and third trimester and did not receive treatment during pregnancy were 4 549 (20.23%), 8 719 (38.78%), 2 235 (9.94%) and 6 980 (31.05%), respectively. Compared with pregnant women who started treatment in the first trimester, pregnant women who did not receive anti-syphilis treatment during pregnancy had increased risks of neonatal preterm birth (OR=1.42, 95%CI: 1.24-1.62), death (OR=4.27, 95%CI: 1.64-14.69) and congenital syphilis (OR=12.26, 95%CI: 6.35-27.45). At the same time, the risk of congenital syphilis in the newborns of pregnant women who started anti-syphilis treatment in the second trimester (OR=2.68, 95%CI: 1.34-6.16) and third trimester (OR=6.27, 95%CI: 2.99-14.80) also increased. Conclusion: Early initiation of anti-syphilis treatment during pregnancy in patients with syphilis can improve neonatal outcomes.

The use of convalescent plasma therapy in the management of a pregnant woman with COVID-19: a case report

ABSTRACT The coronavirus disease 19 (COVID-19) is responsible for the current worldwide pandemic. Treatment and prophylaxis are still under investigation. Convalescent plasma therapy could be an alternative. We report a case of a 41-year-old patient, at 28 weeks of gestation, was hospitalized with COVID-19. On the 10th day after onset of symptoms, the clinical picture worsened, and she required high-flow oxygen therapy (30L/minute), with 92% oxygen saturation, and chest X-ray showing mild bilateral opacities at lung bases. Blood tests showed D-dimer 1,004ng/mL, C-reactive protein 81mg/L, pro-calcitonin 0.05ng/mL and interleukine-6 42.9pg/mL. The therapy chosen was Tazocin® 12g/day, vancomycin 2g/day, and methylprednisolone 40mg/day. In addition, convalescent plasma therapy was administered (275mL) uneventfully, including SARS-CoV-2 antibodies and neutralizing antibodies >1:160. The patient had a fast recovery. The early administration of convalescent plasma, with high titers of neutralizing antibodies, may be an alternative option for severe COVID-19 during pregnancy, until further studies demonstrate an efficient and safe treatment or prophylaxis.

Transmisión vertical de hepatitis B: importancia de incorporar el cribado en el control prenatal en Chile / Vertical transmission of hepatitis B: the importance of incorporating screening during pregnancy in Chile

Resumen La transmisión vertical de hepatitis B es responsable de 50% de las infecciones en el mundo e implica 90% de riesgo de evolucionar a hepatitis crónica y sus complicaciones. La inmunoprofilaxis postparto (inmunoglobulina más vacuna) es la medida de prevención más efectiva. Sin embargo, puede existir fracaso a pesar de dicha intervención, debido a factores como alta carga viral o la presencia de HBeAg en la madre, los que sólo pueden evitarse si se hace el diagnóstico y tratamiento durante la gestación. En Chile, en el año 2019 se incorporó la vacunación en los recién nacidos, pero no existe aún cribado durante el embarazo, a diferencia de los países desarrollados. En los últimos años se ha experimentado un aumento acelerado de inmigración proveniente principalmente de América latina y el Caribe, con prevalencias altas en algunos de ellos. Chile debiese avanzar prontamente hacia el cribado de hepatitis B en embarazo.

Abstract Half of cases of hepatitis B around the world are produced from vertical transmission; and 90% of them can evolve to chronic hepatitis and their long term complications. Postpartum immunoprophylaxis (immunoglobulin and vaccine) is the most effective preventive measure. However, despite this prophylaxis, vertical transmission is possible if the mother presents a high viral load or e-antigen. This risk can be reduced only if screening during pregnancy and treatment if needed, are incorporated. In 2019, vaccination for hepatitis B in newborn was incorporated in Chile, but not yet prenatal screening, unlike developed countries. Chile has experienced a growth in immigration from Latin America and Caribbean, some countries with high endemicity included. Prenatal screening in Chile should be promptly incorporated.

Adequacy of prenatal care, diagnosis and treatment of syphilis in pregnancy: a study with open data from Brazilian state capitals / Adequação de atendimento pré-natal, diagnóstico e tratamento da sífilis gestacional: um estudo com dados abertos de capitais brasileiras / Adecuación de la atención prenatal, diagnóstico y tratamiento de la sífilis en el embarazo: un estudio con datos abiertos en siete capitales brasileñas

Abstract: To assess the adequacy of prenatal care offered in the Brazilian capital cities and the diagnosis of gestational syphilis through public data from health information systems. The modified Kotelchuck index for adequacy of prenatal care was built using Brazilian Information System on Live Births (SINASC) data. Data on gestational syphilis, congenital syphilis, estimated population coverage by the Family Health Strategy (FHS), the Municipal Human Development Index (MHDI) and data from National Program for Access and Quality Improvement in Primary Care (PMAQ-AB) were accessed in public sites. The profile of pregnant women associated with inadequate care was assessed by logistic regression. In total, 685,286 births were analyzed. Only 2.3% of women did not attend prenatal appointments. The mean adequacy was 79.7%. No correlation was found between adequacy of prenatal care and FHS coverage (p = 0.172), but a positive correlation was found with the MHDI (p < 0.001). Inadequacy of prenatal care was associated with age below 20 years old, schooling less than 4 years, non-white skin color and not having a partner. Among the congenital syphilis cases, 17.2% of mothers did not attend prenatal care. Gestational syphilis more often affected vulnerable women, including a higher proportion of adolescents, women with low schooling, and women of non-white color. The PMAQ-AB showed a median availability of 27.3% for syphilis rapid tests, 67.7% for benzathine penicillin, and 86.7% for benzathine penicillin administration by health teams. The use of public data showed a low adequacy of prenatal care in Brazilian capitals, denoting insufficient quality for the diagnosis and treatment of gestational syphilis, despite the availability of supplies. Continuous monitoring can be carried out using public data, indicating to local strategies to eliminate congenital syphilis.

Resumo: O estudo buscou avaliar a adequação do atendimento pré-natal oferecido nas capitais brasileiras e o diagnóstico da sífilis gestacional através de dados públicos dos sistemas de informação de saúde. Foi construído o indicador de Kotelchuck modificado para adequação do atendimento pré-natal, usando dados do Sistema de Informações sobre Nascidos Vivos (SINASC). Foram acessados em sites públicos os dados sobre sífilis gestacional, sífilis congênita, estimativa da cobertura populacional pela Estratégia Saúde da Família (ESF), Índice de Desenvolvimento Humano (IDH) municipal e dados do Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica (PMAQ-AB). O perfil das gestantes associado ao atendimento inadequado foi avaliado com base na regressão logística. Foram analisados um total de 685.286 nascimentos. Apenas 2,3% das mulheres não receberam atendimento pré-natal. A taxa média de adequação foi de 79,7%. Não foi encontrada correlação entre a adequação do pré-natal e a cobertura pela ESF (p = 0,172), mas houve correlação com o IDH municipal (p < 0,001). A inadequação da assistência pré-natal mostrou associação com a idade < 20 anos, escolaridade < 4 anos, raça/cor não-branca e situação conjugal sem companheiro. Entre os casos de sífilis congênita, 17,2% das mães não haviam recebido atendimento pré-natal, e a sífilis gestacional afetava mais as gestantes vulneráveis, incluindo uma proporção maior de adolescentes, mulheres com baixa escolaridade e mulheres não brancas. O PMAQ-AB mostrou uma disponibilidade mediana de 27,3% de testes rápidos para sífilis, 67,7% para penicilina benzatina e 86,7% para administração de penicilina benzatina pela equipe de saúde. O uso de dados públicos revelou baixa adequação do atendimento pré-natal nas capitais brasileiras, denotando qualidade insuficiente para o diagnóstico e tratamento da sífilis gestacional, apesar da disponibilidade de insumos. O monitoramento contínuo pode ser realizado com o uso de dados públicos, indicando estratégias locais para eliminar a sífilis congênita.

Resumen: El objetivo de este trabajo ha sido evaluar la adecuación de la atención prenatal que se ofreció en capitales brasileñas, y el diagnóstico de sífilis gestacional, mediante datos públicos de los sistemas de información de salud. El indicador modificado de Kotelchuck para la adecuación de la atención prenatal se construyó usando datos del Sistema de Información sobre Nacidos Vivos (SINASC). La información sobre sífilis gestacional, sífilis congénita, así como la cobertura de población estimada por la Estrategia Salud de Familia (ESF), Índice de Desarrollo Humano (IDH) municipal y datos del Programa Nacional para el Acceso Mejorado y Calidad de la Atención Básica (PMAQ-AB) se recabaron de sitios web públicos. El perfil de las mujeres embarazadas asociado con el cuidado inadecuado fue evaluado mediante regresión logística. En total, se analizaron 685.286 nacimientos. Solamente un 2,3% de las mujeres no atendieron a citas prenatales. La adecuación media fue de un 79,7%. No se encontró correlación entre la adecuación del cuidado prenatal y la cobertura de la ESF (p = 0,172), pero se encontró una correlación positiva con el MHDI (p < 0,001). La inadecuación del cuidado prenatal estuvo asociada con una edad < 20 años, escolaridad < 4 años, raza no blanca y no tener pareja. Entre los casos de sífilis congénita, un 17,2% de las madres no asistieron a la atención prenatal. La sífilis gestacional afectó más a menudo a las mujeres vulnerables, incluyendo una más alta proporción de adolescentes, mujeres con baja escolaridad, y mujeres de color no blanco. La PMAQ-AB mostró un promedio de disponibilidad de un 27,3%, en el caso de test rápidos de sífilis, un 67,7% para la penicilina benzatínica, y un 86,7% para la administración penicilina benzatínica por equipos de salud. El uso de los datos públicos mostró una baja adecuación del cuidado prenatal en capitales brasileñas, denotando una insuficiente calidad para el diagnóstico y tratamiento de la sífilis gestacional, a pesar de la disponibilidad de suministros. La supervisión continua se puede llevar a cabo usando datos públicos, apuntando a estrategias locales para eliminar la sífilis congénita.

Follow-up of toxoplasmosis during pregnancy: ten-year experience in a University hospital in southern Brazil / Acompanhamento da toxoplasmose durante a gravidez: uma década de experiência em um hospital universitário no Sul do Brasil

Abstract Objective To describe a population of pregnant women diagnosed with toxoplasmosis and their respective newborns, describing the hospital protocol for treatment and follow-up. Methods Retrospective cohort of pregnant women with acute toxoplasmosis infection and risk of transplacental transmission who were sent to the Fetal Medicine Group of Hospital de Clínicas de Porto Alegre (HCPA) between - January 1, 2006 and December 31, 2016. All patients with confirmed disease were included. The diagnostic protocol and treatment were applied; a polymerase chain reaction (PCR) analysis of the amniotic fluid was used to diagnose toxoplasmosis and determine the treatment. The newborns were followed up at the pediatric outpatient clinic specializing in congenital infection. The patients who were not followed up or were not born in the HCPA were excluded. Results A total of 65 patients were confirmed to have gestational toxoplasmosis; 40 performed amniocentesis, and 6 (15%) were identified as having positive PCR in the amniotic fluid. In five of those cases, this result associated with the gestational age defined the triple therapy during pregnancy, and in one case, it defined the monotherapy (advanced gestational age). A total of 4 of these newborns were treated from birth with triple therapy for 10months, 1 was not treated (due to maternal refusal), and 1 progressed to death within the first 54 hours of life due to complications of congenital toxoplasmosis. Of the 34 remaining cases with a negative PCR, 33 were treated with monotherapy and 1 was treated with triple therapy (ultrasound findings); of these children, 9 (26.5%) presented negative immunoglobulin G (IgG), 24 (70.6%) presented positive IgG (but none presented positive immunoglobulin M [IgM]), and 1 (2,9%) presented alterations compatible with congenital disease and started treatment with the triple therapy soon after birth. Out of the total sample of 60 patients, among the 25 who did not perform amniotic fluid PCR, 5 were treated with triple therapy (ultrasound findings/prior treatment) and 20 patients were submitted to monotherapy; only two newborns underwent treatment for congenital toxoplasmosis. Among the 65 cases of gestational toxoplasmosis, 6 (9,2%) children had a diagnosis of congenital toxoplasmosis, and 2 patients with triple therapy felt severe adverse effects of the medications. Conclusions The present study suggests that research on PCR screening of the amniotic fluid may be useful to identify patients with a higher potential for fetal complications, who may benefit from the poly-antimicrobial treatment. Patients with negative PCR results must continue to prevent fetal infection with monotherapy, without risk of fetal or maternal impairment.

Resumo Objetivo Descrever uma população de pacientes diagnosticadas com toxoplasmose na gestação e seus respectivos recém-nascidos, relatando o protocolo do hospital durante o tratamento e seguimento. Métodos Coorte retrospectiva de gestantes com infecção aguda por toxoplasmose e risco de transmissão transplacentária, encaminhadas para acompanhamento pelo Grupo deMedicina Fetal doHospital de Clínicas de Porto Alegre (HCPA) entre 1o de janeiro de 2006 e 31 de dezembro de 2016. Todas as pacientes comdoença confirmada foram incluídas. O protocolo de diagnóstico e tratamento foi aplicado; uma análise da reação em cadeia da polimerase (RCP) no líquido amniótico foi utilizada para diagnosticar a toxoplasmose e determinar o tratamento. Os recém-nascidos foram acompanhados no ambulatório de pediatria especializadoeminfecções congênitas. Pacientes que não foramseguidas ou cujo parto não foi feito no hospital foram excluídas. Resultados A toxoplasmose gestacional foi confirmada em 65 pacientes; 40 realizaram amniocentese, e 6 (15%) foram identificadas com RCP positiva no líquido amniótico. Este resultado associado à idade gestacional definiu a terapia tríplice durante a gestação em 5 casos, e a monoterapia em 1 caso (por idade gestacional avançada). Quatro destas crianças foram tratadas desde o nascimento com terapia tríplice por 12 meses, 1 não foi tratada (por recusa materna), e 1 evoluiu com óbito dentro das primeiras 54 horas de vida devido a complicações da toxoplasmose congênita. Dos 34 casos remanescentes com RCP negativa, 33 foram tratados com monoterapia, e 1 foi tratado com terapia tríplice (por achados ultrassonográficos); destes recém-nascidos, 9 (26,5%) tiveram imunoglobulina G (IgG) negativa, 24 (70,6%) tiveram IgG positiva, mas nenhum apresentou imunoglobulina M (IgM) positiva, e 1 (2,9%) apresentou alterações compatíveis comdoença congênita e iniciou a terapia tríplice logo após o nascimento. Entre as 25 pacientes que não fizeram RCP no líquido amniótico, 5 foram tratadas com terapia tríplice (por achados ultrassonográficos/ tratamento prévio) e 20 receberam monoterapia; somente 2 recém-nascidos receberam tratamento para toxoplasmose congênita. Entre os 65 casos de toxoplasmose gestacional, 6 (9,2%) recém-nascidos tiveram o diagnóstico de toxoplasmose congênita. Um total de 2 pacientes submetidas à terapia tríplice apresentaram efeitos adversos severos das medicações utilizadas. Conclusão Este estudo sugere que a triagem da RCP para toxoplasmose do líquido amniótico pode ser útil no rastreamento de pacientes com maior potencial para complicações fetais, que podem se beneficiar do tratamento poli antimicrobiano. Pacientes com RCP negativa devem continuar a prevenir a infecção fetal com monoterapia, sem risco de comprometimento fetal ou materno.

Calidad del seguimiento a la exposición perinatal al HIV y observancia de las estrategias reconocidas para disminuir su transmisión en un centro de referencia de Medellín / Follow up of HIV perinatal exposure and accomplishment of strategies to reduce the risk of viral transmission, experience in a reference hospital in Medellín

Resumen Introducción. La prevención de la transmisión materno-infantil del virus de la inmunodeficiencia humana (Human Immunodeficiency Virus, HIV) es una estrategia fundamental para evitar la infección en niños. A nivel local, se desconoce la situación de las mujeres gestantes infectadas por HIV y el grado de observancia de las estrategias reconocidas mundialmente para disminuir la transmisión perinatal. Objetivo. Describir las características sociodemográficas y clínicas de las mujeres gestantes con HIV y de sus hijos en un centro de referencia de Medellín. Materiales y métodos. Se hizo un estudio descriptivo retrospectivo entre 2012 y 2015 mediante la revisión de las historias clínicas de las mujeres gestantes con HIV y de sus neonatos habidos en partos atendidos en el Hospital San Vicente Fundación. Se describieron las variables de atención prenatal, parto, recién nacido y seguimiento de los neonatos. Resultados. Se analizaron 106 madres y sus hijos expuestos al HIV. El 39,6 % de las mujeres gestantes conocía el diagnóstico antes del embarazo y al 58,5 % se le diagnosticó durante este. El 95,3 % de las mujeres gestantes asistió a control prenatal, 46,5 % de ellas a partir del primer trimestre. Si bien el 95 % recibió antirretrovirales, el 23,9 % comenzó a tomarlos tardíamente en el tercer trimestre. Solo el 63 % de las mujeres registró carga viral para el HIV después de la semana 34 de gestación. El 90,6 % de los partos fueron por cesárea, y el virus del papiloma humano y la sífilis fueron las principales infecciones concomitantes. Se hizo seguimiento de 103 niños (no fue posible localizar a tres de ellos para el seguimiento), a ninguno se le confirmó la presencia del HIV y, en el 88 %, se descartó. Conclusiones. En este estudio, no se registraron casos de transmisión perinatal. Sin embargo, siguen presentándose fallas y retrasos en la atención prenatal y en la oportunidad del seguimiento materno para confirmar oportunamente el HIV y para detectar tempranamente infecciones maternas concomitantes que eviten la morbilidad y las secuelas en los neonatos.

Abstract Introduction: Prevention of mother-to-child transmission of the human immunodeficiency virus (HIV) is essential to limit the spread of the disease. Colombian data about HIV infection in pregnancy are scarce, as well as on the results of the strategies used worldwide to reduce perinatal transmission. Objective: To describe the characteristics and outcomes of pregnant women infected with HIV and their children in a reference center in Medellín. Materials and methods: We conducted a retrospective observational study for the 2012- 2015 period by studying the clinical records of newborns exposed to HIV and their mothers. We evaluated the characteristics of prenatal care, deliveries, and infant postnatal care, as well as the follow-up data to confirm or exclude HIV transmission. Results: We included 106 infants and their mothers. We found that 39,6% of mothers knew about the HIV diagnosis before pregnancy and 58,5% were diagnosed during pregnancy; 95.3% of them attended prenatal controls, but only 46.5% as of the first trimester; 95% of them received antiretrovirals, but 23.9% started therapy just during the third trimester. Only 63% of women had a viral load for HIV after 34 weeks of gestation. None of the 103 children with follow up had confirmed presence for HIV and in 88% of them, it was discarded. Conclusions: No cases of perinatal HIV transmission were found in the study. However, difficulties and delays persist in prenatal care, in timely maternal follow-up to confirm or discard HIV, and for early detection of maternal co-infections and their effects on newborns.

The use of mobile educational tools to improve antimicrobial prescription for the treatment of acute pyelonephritis in pregnancy: A retrospective cross-sectional study / O uso de ferramentas educacionais móveis para o aperfeiçoamento da prescrição médica do tratamento de pielonefrite aguda na gestação: estudo transversal retrospectivo

Abstract Objective To analyze the prescription of antimicrobial agents for pregnant women admitted into the obstetrics service who presented with acute pyelonephritis. Methods Three cross-sectional studies were performed comparing the prescription of antimicrobials for pyelonephritis in pregnant women in the time periods evaluated (2010-2011: 99 patients evaluated; 2013: 116 patients evaluated; 2015: 107 patients evaluated), at the Hospital Fêmina, Porto Alegre, in the state of Rio Grande do Sul, Brazil. The analysis was performed before and after the promotion of an institutional protocol for the treatment of pyelonephritis during pregnancy, and on a third occasion after the introduction of a smartphone-based mobile educational tool. Results The evaluation of the prescribing physicians and the adequacy of the prescriptions between the different periods studied revealed a significant increase in appropriate conduct for the choice of antimicrobial (2010: 83.8%; 2013: 95.7%; and 2015: 100%), route of administration (2010: 97%; 2013: 100%; and 2015: 100%), and interval (2010: 91.9%; 2013: 95.7%; and 2015: 100%), following the introduction of the protocol, and again after the implementation of the softwareapplicationwithorientationsontheantimicrobial treatment. Conclusion The use of specific mobile applications should be encouraged to attain a better quality and accuracy in prescriptions and to include strategies that not only reduce the risk of negative outcomes, but also improve the quality of care and treatment for maintaining the health both of the mother and of the baby.

Syphilis in pregnancy: the reality in a public hospital / Sífilis na gestação: a realidade em um hospital público

Abstract Objective: The present study assessed epidemiological and obstetrical data from pregnant women with syphilis at the Hospital de Clínicas of the Universidade Federal do Triângulo Mineiro (UFTM, in the Portuguese acronym), describing this disease during pregnancy and its vertical transmission for future healthcare actions. Methods: Records from pregnant women who had been admitted to the Obstetrics Department of the Hospital de Clínicas of the UFTM and were diagnosed with syphilis between 2007 and 2016 were reviewed. A standardized form was used to collect epidemiological, obstetric data and outcomes of congenital infection. The present research has been authorized by the Ethics Committee of the institution. Results: There were 268 women diagnosed with syphilis, with an average age of 23.6 years old. The majority of the patients were from Uberaba. Inadequate prenatal care was observed in 37.9% of the pregnant women. Only 34.2% of the patients completed the treatment according to the guidelines issued by the Ministry of Health of Brazil, and 19.8% of the partners of the patients underwent adequate syphilis treatment; 37 (13.8%) couples (patients and partners) underwent correct treatment. Regarding the obstetric outcomes, 4 (1.5%) patients had a miscarriage and 8 (3.4%) had fetal losses (from the fetal loss group, 7 had no adequate treatment); 61 (25.9%) patients had premature births - this prematurity has been significantly correlated to inadequate or incomplete treatment in 49 (27.9%) patients, compared with 12 (13.0%) patients with premature births and adequate treatment (p = 0.006). The average live newborn weight was 2,840 g; 25.3% had a birth weight < 2,500 g; 74.2% had congenital syphilis, a data with heavy correlation to inadequate or incomplete prenatal care, prematurity, and low birth weight. Conclusion: Public awareness policies on adequate prenatal care, intensification of serological screening, and early treatment of syphilis are needed, considering the rise of cases diagnosed during gestation and its potentially preventable deleterious consequences related to congenital transmission.

Resumo Objetivo: O presente estudo avaliou dados epidemiológicos e obstétricos de gestantes com sífilis no Hospital de Clínicas da Universidade Federal do Triângulo Mineiro (UFTM), objetivando o conhecimento desta infecção no ciclo gravídico e a transmissão vertical para futuras ações em saúde pública. Métodos: Foram revisados registros de gestantes admitidas no Departamento de Ginecologia e Obstetrícia do Hospital de Clínicas da UFTM, diagnosticadas com sífilis entre 2007 e 2016. Para a coleta de dados, utilizou-se um formulário padronizado enfocando aspectos epidemiológicos, obstétricos e infecção congênita. A presente pesquisa foi autorizada pelo Comitê de Ética da instituição. Resultados: Obteve-se 268 gestantes diagnosticadas com sífilis, com idade media de 23,6 anos, sendo a maioria de Uberaba. A assistência pré-natal foi inadequada em 37,9% dos casos. O tratamento para sífilis, de acordo com as diretrizes do Ministério da Saúde do Brasil, foi realizado por 34,2% das gestantes e por 19,8% dos parceiros. Quanto aos desfechos obstétricos, observou-se que 4 (1,5%) pacientes evoluíram com abortamento e 8 (3,4%) com óbito fetal, das quais 7 não realizaram tratamento. Observou-se parto prematuro em 61 (25,9%) gestantes, e a prematuridade foi significativamente associada ao tratamento ausente/incompleto, com 49 (27,9%) casos, comparada a 12 (13,0%) casos nos quais o tratamento foi adequado (p = 0,006). Quanto aos recém-nascidos, o peso médio foi de 2.840 g, e 25,3% apresentaram peso < 2.500 g. Diagnosticou-se infecção congênita em 74,2%, dos casos, associada significativamente ao pré-natal inadequado, ao tratamento ausente/ incompleto, à prematuridade e ao baixo peso ao nascer. Conclusão: Políticas públicas de conscientização sobre pré-natal adequado, intensificação de rastreamento sorológico e tratamento precoce da sífilis são necessárias, haja vista a ascensão dos casos diagnosticados na gestação e suas consequências deletérias potencialmente evitáveis relacionadas à transmissão congênita.

Review of the missed opportunities for the prevention of vertical transmission of HIV in Brazil

OBJECTIVE: The present literature review aims to highlight gaps in the treatment of preventative mother-to-child HIV transmission and the risk factors in Brazil. METHODS: Among the 425 articles identified in SciELO and PubMed searches, 59 articles published between 1994 and 2016 were selected for reading and data extraction, and 33 articles were included in the present review. RESULTS: The rates of vertical HIV transmission described in the studies varied widely, from 1.8% to 27.8%, with a significant reduction over the years. However, recent rates were also found to be variable in different regions of Brazil, and despite the significant reduction in mother-to-child transmission, many gaps remain in prevention services. A failure to attend prenatal care is the main factor associated with the increased risk of vertical transmission of HIV, hindering early maternal diagnosis and the completion of preventative measures during the prenatal period and, often, the peripartum and postnatal periods. A small number of studies discussed the sociodemographic factors, including a low level of education for pregnant women and the inadequacies of health services, such as difficulties scheduling appointments and undertrained staff, associated with vertical transmission. As such, the current challenge is to better define the sociodemographic and infrastructural factors that increase the risk of mother-to-child transmission of HIV to provide the necessary investments to promote an earlier inclusion of these populations in prevention services. CONCLUSIONS: This review may serve as a guide for future programs to focus efforts on the prevention of vertical HIV transmission.

Sepse em gestantes atendidas em um hospital público de Curitiba - PR / Sepsis in pregnant women attended at a public hospital in Curitiba - PR

OBJETIVO: Avaliar a frequência de sepse em gestantes e puérperas atendidas em um hospital, identificar os principais focos originários de sepse na gestação e puerpério, e verificar os principais agentes etiológicos envolvidos em sua etiopatogenia. MÉTODOS: Estudo do tipo transversal descritivo realizado no Hospital do Trabalhador, em Curitiba (PR), de agosto de 2014 a agosto de 2016. Revisão e análise de 71 prontuários de pacientes diagnosticadas com sepse, sepse grave ou choque séptico. Os aspectos estudados foram idades gestacional, agente etiológico, foco infeccioso, principal trimestre gestacional acometido e prevalência de cada tipo de sepse. RESULTADOS: A frequência de sepse durante a gestação e o puerpério no período estudado foi de nove casos para cada mil gestantes. A ocorrência de sepse foi relacionada principalmente ao segundo semestre gestacional (39,4%). Os casos de sepse somaram 73,2% do total, enquanto os demais evoluíram com quadros de sepse grave e choque séptico . Escherichia coli representou 33,8%, sendo o urinário o foco infeccioso mais prevalente (70,4%). Ceftriaxona foi o antibiótico mais utilizado, tanto isoladamente quanto em associação (84,4%). Entre os desfechos para o feto, 85,9% não tiveram complicações. CONCLUSÕES: Os novos conceitos de sepse publicados pela Society of Critical Care Medicine (SCCM) e pela European Society of Critical Care Medicine (ESICM) contrariam os interesses dos países conhecidos como de baixos e médios recursos. Foi encontrado aumento da incidência de sepse gestacional, ocorrendo prevalência do foco urinário; consequentemente, o agente principal foi E. coli. Ademais, ocorreram importantes consequências perinatais como mortalidade e prematuridade. (AU)

OBJECTIVE: To evaluate the frequency of sepsis in pregnant and puerperal patients attended in a hospital, and to identify the main focus of sepsis during gestation and puerperium, and check the main etiological agents involved in its pathogenesis. METHODS: This is a cross-sectional and descriptive study carried out at Hospital do Trabalhador (city of Curitiba, state of Paraná), from August 2014 to August 2016. It is a review and analysis of the charts of 71 patient diagnosed with sepsis, severe sepsis, or septic shock. Aspects studied: gestational age, etiologic agent, infectious focus, main affected gestational trimester, and prevalence of each type of sepsis. RESULTS: The frequency of sepsis during pregnancy and puerperium was 9 cases for 1000 pregnant women. The occurrence of sepsis was mainly related to the second gestational semester (39.4%). Severe sepsis and septic shock comprised 73.2% of the cases. Escherichia coli accounted for 33.8%, and the most prevalent infectious focus was urinary (70.4%). Ceftriaxone was the most commonly used antibiotic, both alone and in combination (84.4%). Among the outcomes for the fetus, 85.9% had no complications. CONCLUSIONS: The new concepts of sepsis, published by the Society of Critical Care Medicine (SCCM), and by the European Society of Critical Care Medicine (ESICM) contradict the interests of the countries with low and medium resources. An increase in the incidence of gestational sepsis occurred, with a prevalence of urinary focus; consequently the main agent was Escherichia coli. In addition, there were important perinatal consequences such as mortality and prematurity. (AU)

Staphylococcus sciuri, una causa infrecuente de sepsis materna / Staphylococcus sciuri, a rare cause of maternal sepsis

RESUMEN El Staphylococcus sciuri es un estafilococo coagulasa negativo presente en animales de granja que en raras ocasiones se puede encontrar como microorganismo colonizador en humanos. Su importancia radica en que se ha asociado con infecciones graves como la endocarditis, peritonitis e infección del tracto urinario; constituyendo el 0,79% del número total de estafilococos coagulasa negativos aislados en muestras clínicas. Presentamos el caso de una primigesta de 22 años, con un embarazo de 17,5 semanas. La exploración física inicial evidenció taquicardia y temperatura de 39.3 ° C. Los estudios de laboratorio informaron leucocitos de 25,000, neutrófilos de 83%, plaquetas en 350,000, uroanálisis con marcada piuria, con más de 500 células/uL, nitritos negativos; tinción de Gram de orina con cocos Gram positivos. Después de tres días de tratamiento con Ceftriaxona un gramo cada doce horas intravenosamente, se obtienen informes positivos para S.sciuri multiresistente. Finalmente, se inició manejo con Clindamicina 600 mg cada seis horas intravenosamente, más Gentamicina a dosis de 1 mg/kg cada ocho horas intravenosamente. S.sciuri es una bacteria que se ha encontrado en el ambiente hospitalario y ocasionalmente es aislada en humanos, produciendo infecciones graves. Países como Colombia continúan tratando las infecciones sin tener en cuenta su propio entorno, en el cual los patógenos silvestres son causa frecuente de infecciones, debido al estrecho rango de coexistencia entre animales y humanos en las regiones rurales. Conclusión. Este caso pone de manifiesto la necesidad de considerar como agenta causal aquellos patógenos presentes en animales de granja que pueden causar infecciones en humanos, sobretodo en pacientes que proceden de las áreas lejanas a los centros urbanos.

SUMMARY Staphylococcus sciuri is a negative coagulase staphylococcus present in farm animals that can rarely be found as a colonizing microorganism in humans. Its importance is that it has been associated with serious infections such as endocarditis, peritonitis and urinary tract infection; constituting 0.79% of the total number of coagulase-negative staphylococci isolated in clinical samples. We present the case of a woman in her first pregnancy of 22 years, with a pregnancy of 17.5 weeks. The initial physical examination showed tachycardia and temperature of 39.3 ° C. Laboratory studies reported leukocytes of 25,000, neutrophils of 83%, platelets in 350,000, urinalysis with marked pyuria, with more than 500 cells / uL, negative nitrites; Gram stain of urine with Gram positive cocci. After three days of treatment with Ceftriaxone one gram every twelve hours intravenously, positive reports for multiresistant S. sciuri are obtained. Finally, management was started with Clindamycin 600 mg every six hours intravenously and Gentamicin at a dose of 1 mg / kg every eight hours intravenously. S.sciuri is a bacterium that has been found in the hospital environment and is occasionally isolated in humans, causing serious infections. Countries such as Colombia continue to treat infections without taking into account their own environment, in which wild pathogens are a frequent cause of infections, due to the narrow range of coexistence between animals and humans in rural regions. Conclusion. This case highlights the need to consider as a causal agent those pathogens present in animals that can cause infections in humans, especially in patients who come from areas far away from urban centers.

HIV-1 genetic diversity and resistance to antiretroviral drugs among pregnant women in Ribeirão Preto (SP), Brazil. Cross-sectional study

ABSTRACT BACKGROUND: Increasing genetic diversity of HIV-1 and emergence of drug-resistant mutations may reduce the efficacy of antiretroviral therapy and prophylaxis that are used to prevent mother-to-child transmission. The aim of this study was to assess the genetic diversity and prevalence of drug-resistant mutations among HIV-infected pregnant women. DESIGN AND SETTING: Cross-sectional study at an outpatient clinic for infectious diseases within gynecology and obstetrics. METHODS: This study evaluated the dynamics of HIV-1 subtypes and the prevalence of transmitted and acquired drug-resistant mutations among 38 HIV-infected pregnant women (20 previously exposed to antiretroviral therapy and 18 naive), in Ribeirão Preto (SP), Brazil, between 2010 and 2011. Genotyping was performed by means of molecular sequencing of the protease and reverse transcriptase regions of the HIV-1 pol gene. RESULTS: Subtype B was identified in 84.2% of the samples, recombinant forms between B and F in 7.9%, subtype F1 in 5.3% and the recombinant form K/F in 2.6%. No mutation associated with transmitted drug resistance was detected in the samples from the naive pregnant women, whereas mutations associated with acquired drug resistance were found in 35.0% of the pregnant women previously exposed to antiretroviral therapy. CONCLUSION: The results showed that subtype B predominated, while there was low prevalence of sequences with transmitted drug resistance.

Oral desensitization to penicillin for the treatment of pregnant women with syphilis: A successful program / Dessensibilização oral à penicilina para o tratamento da sífilis na gestação: um exemplo de experiência bem-sucedida

Abstract Gestational syphilis is a prevalent disease in Brazil and other low and medium income countries. Desensitization to penicillin is recommended for pregnant women with syphilis who are allergic to β-lactams. This is a descriptive study utilizing outpatient medical records from 2011 to 2015 from a mother and child hospital that is part of the national healthcare system in the South of Brazil, which performs an average of 3,600 birth assistances per year. All cases of pregnant women with syphilis and presumptive diagnosis of β-lactam allergy during the study period were included. The patients referred for desensitization originated from the hospital prenatal care service, as well as from municipal/state antenatal care services. Oral desensitization was performed in the obstetric emergency room, and adult and pediatric intensive care units were available at all times. Ten patients underwent desensitization during the period of study. Personal history of urticaria was the most common reaction that demanded desensitization. All patients tolerated the procedure well, and showed no adverse reactions.We report a successful program of oral desensitization. None of the patients presented adverse reactions or complications, a fact that corroborates the feasibility and safety of the desensitization protocol. Oral administration of penicillin comes at a low cost, and optimizes the use of time and resources.

Resumo A sífilis gestacional é uma doença prevalente no Brasil e em outros países de baixa e média renda. A dessensibilização à penicilina é recomendada para mulheres grávidas com sífilis que são alérgicas a β-lactâmicos. Este é um estudo descritivo que utiliza registros médicos de 2011 a 2015 de um hospital público materno-fetal do Sul do Brasil com média de 3.600 partos anuais. Foram incluídos todos os casos de gestantes com sífilis e diagnóstico presuntivo de alergia a β-lactâmicos durante o período de estudo. As pacientes encaminhadas para dessensibilização originaram-se do serviço pré-natal hospitalar internamente, bem como dos serviços municipais e estaduais de atendimento pré-natal. A dessensibilização oral foi realizada na sala de emergência obstétrica, e a unidade de terapia intensiva estava disponível em todos os momentos para o atendimento de possíveis intercorrências. Dez pacientes foram submetidas à dessensibilização durante o período estudado. História pessoal de urticária foi a reação mais comum que exigiu dessensibilização à penicilina. Todas as pacientes toleraram bem o procedimento, e não mostraram reações adversas. Relatamos no presente manuscrito um programa bem-sucedido de dessensibilização oral à penicilina. Nenhuma das pacientes apresentou reações adversas ou complicações, corroborando a viabilidade e segurança do protocolo de dessensibilização. A administração oral de penicilina tem baixo custo, e otimiza o uso de tempo e recursos para o tratamento adequado de sífilis gestacional no cenário apresentado.

Prevalence and antimicrobial susceptibility profile of Streptococcus agalactiae in pregnant women seen at the University Hospital of Londrina, Paraná, Brazil / Prevalência e sensibilidade aos antimicrobianos de Streptococcus agalactiae em gestantes atendidas no Hospital Universitário de Londrina, Paraná, Brazil

A retrospective study of pregnant women seen at the University Hospital of Londrina, Paraná, Brazil was performed to determine the prevalence of Group B Streptococcus (GBS) vaginal-rectal colonization, and the GBS susceptibility for antimicrobials used in intrapartum antibiotic prophylaxis. A vaginal-rectal swab was collected from 2,901 women between 35 and 37 weeks of gestation. Of these, 527 (18.2%) had a positive culture for GBS, and 0.4%, 10.2% and 10% of the isolates were resistant to penicillin, erythromycin and clindamycin, respectively. These results highlight the importance of continuous surveillance of GBS colonization in pregnant women for preventing GBS infections in neonates.

Um estudo retrospectivo foi realizado com gestantes atendidas no Hospital Universitário de Londrina, Paraná, Brasil para determinar a prevalência de colonização vaginal-retal por estreptococos do Grupo B (EGB) e o perfil de sensibilidade de EGB aos antimicrobianos utilizados para a antibioticoterapia profilática intraparto. Swabs vaginais-retais foram coletados de 2.901 mulheres entre a 35ª e 37ª semana de gestação. Destes, 527 (18,2%) apresentaram cultura positiva para EGB, e 0,4%, 10,2% e 10% dos isolados foram resistentes à penicilina, eritromicina e clindamicina, respectivamente. Estes resultados destacam a importância de vigilância contínua da colonização por EGB em gestantes para a prevenção de infecções em neonatos por EGB.
