Infección tardía por Streptococcus agalactiae asociada a la leche humana: reporte de 3 casos clínicos / Streptococcus agalactiae late onset infection associated with human milk: three cases report

La infección por estreptococo ß-hemolítico del grupo B o Streptococcus agalactiae puede causar morbilidad grave y mortalidad en los recién nacidos, especialmente en prematuros. Las estrategias de prevención actuales han sido eficaces en reducir la frecuencia de sepsis neonatal temprana ocasionada por transmisión vertical. La incidencia de sepsis tardía por dicho microrganismo no se ha modificado y la vía de infección es menos clara. En niños amamantados, la transmisión a través de la leche materna es posible. Se presentan tres casos de infección tardía por estreptococo ß-hemolítico del grupo B en recién nacidos prematuros alimentados con leche materna cuyas madres tenían mastitis. En todos los casos, tanto en el cultivo de la leche materna como en los hemocultivos de los neonatos se desarrolló el mismo microrganismo.

Group B ß-hemolytic Streptococcus or Streptococcus agalactiae is a major cause of morbidity and mortality in neonates, especially in premature infants. Current prevention strategies have been effective in reducing the frequency of early onset neonatal sepsis caused by vertical transmission. The incidence of late onset sepsis due to this microorganism has not changed and the route of infection is less clear. In breastfed infants, transmission through breast milk is possible. We report three cases of late group B ß-hemolytic streptococcal infection in breastfed preterm infants whose mothers had mastitis. In all cases, both the breast milk culture and the blood cultures of the neonates developed the same microorganism.

Informe sobre transmisión vertical de la hepatitis B en el Hospital Materno Infantil Sardá de la Ciudad de Buenos Aires durante el período 2018-2020 / Report on vertical transmission of hepatitis B at Hospital Materno Infantil Sardá in the City of Buenos Aires for the period 2018-2020

La hepatitis B es una infección vírica que afecta al hígado, puede dar lugar tanto a un cuadro agudo como a una enfermedad crónica, y se transmite por la vía sexual, vertical y parenteral. En este informe, se describe la situación mundial y nacional de esta patología, y su transmisión vertical, así como la caracterización de niños expuestos al virus durante el embarazo, nacidos en el Hospital Materno Infantil Ramón Sardá entre 2018 y 2021.

Retorno social de la inversión tras eliminar la transmisión vertical de chagas, VIH/sida, HB y sífilis: caso de un municipio de la Provincia de Buenos Aires / Social Return on the investment of the elimination of the vertical transmission of Chagas, HIV / AIDS, HB and Syphilis: Case of a Municipality of the Province of Buenos Aires

Resumen Introducción: se busca cuantificar los retornos de la inversión asociados a una intervención en el sistema público de salud de un municipio de la Provincia de Buenos Aires, Argentina, consistente en el fortalecimiento de la estrategia denominada Eliminación de la Transmisión Maternoinfantil de la Infección por VIH, Sífilis, enfermedad de Chagas Congénita e Infección Perinatal por Hepatitis B (ETMI-PLUS). Metodología: el estudio (cuantitativo) se basa en la metodología de Retorno Social de la Inversión (RSI). Se establecieron definiciones ad-hoc para la medición de los retornos sobre la base de los datos disponibles provenientes de diversas fuentes: información primaria de la Secretaría de Salud del MAB; tasas de transmisión congénita de cada enfermedad notificados al Sistema Nacional de Vigilancia de Salud; presupuestos detallados de los recursos asignados al proyecto por parte de la Fundación Mundo Sano y costos de tratamientos e insumos de nomencladores oficiales. Resultados: por cada peso invertido para reforzar la ETMI-PLUS en el MAB, se obtuvo un retorno de casi 4 pesos, gracias a las mejoras en la eliminación vertical de las cuatro enfermedades y al descenso de las complicaciones cardiacas en las mujeres embarazadas diagnosticadas con chagas y tratadas oportunamente. Conclusiones: estos resultados sugieren la existencia de una relación retorno-inversión favorable, analizada bajo una perspectiva conservadora, ya que, se incluyen exclusivamente los ahorros para el sistema de salud y se excluyen otras dimensiones de los retornos vinculadas con las mejoras en los resultados alcanzados.

Abstract Introduction: we seek to quantify the returns on investment associated with an intervention in the public health system of a Municipality of the Province of Buenos Aires, Argentina. This intervention consists of strengthening the strategy for the Elimination of Mother-to-Child Transmission of HIV Infection, Syphilis, Congenital Chagas Disease and Perinatal Hepatitis B Infection, a strategy called ETMI-PLUS. Methodology: the study (quantitative) is based on the Social Return on Investment (RSI) methodology. Ad-hoc definitions are established for the measurement of returns based on the information available from various sources: primary information from the Ministry of Health of the MAB; rates of congenital transmission of each disease reported to the National Health Surveillance System; detailed budgets of the resources assigned to the project by Fundación Mundo Sano and costs of treatments and supplies from official nomenclators. Results: for each argentinean peso invested in strengthening the ETMI-PLUS in the MAB, a return of almost 4 pesos would have been obtained thanks to the improvements in the vertical elimination of the 4 diseases and the reduction of cardiac complications in pregnant women.Conclusions: these results suggest the existence of a return / investment relationship favorable to the intervention, analyzed under a conservative analysis since savings for the health system are exclusively included and other dimensions of returns associated with improvements in results are excluded.

Effect of intrapartum antibiotic prophylaxis of group B streptococcus infection on the incidence and bacteriological profile of early-onset neonatal sepsis / 中国当代儿科杂志

OBJECTIVES@#To study the effect of intrapartum antibiotic prophylaxis (IAP) of group B streptococcus (GBS) infection on the incidence and bacteriological profile of early-onset neonatal sepsis (EONS).@*METHODS@#A retrospective analysis was performed on the medical data of 494 pregnant women with positive GBS screening results and 526 neonates born by these women. According to whether the pregnant woman received IAP, the neonates were divided into two groups: IAP (n=304) and control (n=222). The two groups were compared in terms of clinical indices, incidence rate of EONS, and distribution of pathogenic bacteria in blood culture.@*RESULTS@#Compared with the control group, the IAP group had a significantly lower proportion of children with abnormal clinical manifestations (P<0.001) and a significantly lower incidence rate of EONS (P=0.022). In the IAP group, Escherichia coli (2.3%) was the most common type of pathogenic bacteria in blood culture of the neonates with EONS, while GBS (3.2%) was the most common type of pathogenic bacteria in the control group. The IAP group had a significantly higher detection rate of ampicillin-resistant Escherichia coli than the control group (P=0.029).@*CONCLUSIONS@#Although IAP can significantly reduce the incidence rate of EONS in neonates born to pregnant women with positive GBS screening results, the infection rate of ampicillin-resistant Escherichia coli may increase after IAP treatment. Therefore, it is needed to enhance the monitoring of blood culture results of neonates with EONS and timely adjust treatment plan according to drug susceptibility test results.

Prevención de la transmisión maternoinfantil del virus de la hepatitis B. directrices sobre la profilaxis con antivirales en el embarazo / Prevention of mother-to-child transmission of hepatitis B virus. guidelines on antiviral prophylaxis in pregnancy

Según estimaciones de la Organización Mundial de la Salud (OMS), en el 2015 257 millones de personas en el mundo tenían la infección crónica por el virus de la hepatitis B (VHB) y 900 000 fallecieron a causa de ella, en la mayor parte de los casos de cirrosis o carcinoma hepatocelular. La mayoría de las defunciones asociadas con el VHB en personas adultas obedecen a infecciones contraídas al nacer o en los cinco primeros años de vida. En mayo del 2016, la Asamblea Mundial de la Salud aprobó la Estrategia mundial del sector de la salud contra las hepatitis víricas 2016-2021, en la que se hace un llamado a eliminar las hepatitis virales como amenaza de salud pública ­definida como una reducción de 90% de la incidencia de infecciones y una reducción de 65% de la mortalidad­ para el 2030. La eliminación de la infección por el VHB como amenaza de salud pública conlleva la necesidad de reducir la prevalencia del antígeno de superficie del virus de la hepatitis B (HBsAg) a menos de 0,1% en los niños de 5 años de edad. Esta meta se puede lograr mediante la vacunación de todos los recién nacidos contra la hepatitis B y otras intervenciones orientadas a prevenir la transmisión maternoinfantil del VHB

COVID-19, embarazo, vacunas y lactancia materna / COVID-19, pregnancy, vaccines and breastfeeding

Las mujeres embarazadas o en período de lactancia han sido excluidas de los ensayos clínicos sobre vacunas contra SARS-CoV-2, evitando así la obtención de datos sólidos que permitan determinar la seguridad e inmunogenicidad de las vacunas en esta población, a la vez que se han asociado peores resultados maternos ­ fetales. La evidencia acerca de la seguridad e inmunogenicidad en esta población es limitada, en base a estudios observacionales, con pocos casos y en mujeres vacunadas con plataformas ARNm, en las cuales no se ha descrito por ahora una mayor asociación a eventos adversos relacionados a vacunas, como tampoco, variaciones significativas en la respuesta inmunológica en comparación a la población no embarazada. También existen datos que documentan la adquisición de anticuerpos transplacentarios, considerándose de bajo riesgo la posibilidad de transmisión vertical. Se hacen necesarios ensayos clínicos que permitan precisar recomendaciones basadas en evidencia para esta población, en un contexto de utilización de emergencia de vacunas contra SARS-CoV-2. (AU)

Pregnant or breastfeeding women have been excluded from clinical trials on vaccines against SARSCoV-2, thus avoiding obtaining solid data to determine the safety and immunogenicity of vaccines in this population, as well as being associated worse maternal-fetal outcomes. The evidence about safety and immunogenicity in this population is limited, based on observational studies, with few cases and in women vaccinated with mRNA platforms, in which a greater association to adverse events related to vaccines has not been described or significant variations in the immune response compared to the non-pregnant population. There are also data that document the acquisition of transplacental antibodies, considering the possibility of vertical transmission as low risk. Clinical trials are necessary to evidence-based recommendations for this population, in a context of emergency use of vaccines against SARSCoV-2. (AU)

Consenso Argentino de toxoplasmosis congénita 2020 / Argentine Consensus of congenital toxoplasmosis

Resumen La transmisión vertical de la infección por Toxoplasma gondii ocurre cuando la madre se infecta por primera vez en el transcurso del embarazo. El diagnóstico de la infección materna y la del re cién nacido se logra con el conjunto de pruebas serológicas, hallazgos clínicos y ecográficos. El reconocimiento temprano de la infección materna permite un tratamiento que reduce la tasa de transmisión y el riesgo de daño en el producto de la concepción. El objetivo de este consenso de expertos fue revisar la literatura científica para actualizar las recomendaciones de práctica clínica respecto de la prevención, el diagnóstico y el tratamiento de la toxoplasmosis congénita en nuestro país.

Abstract Mother-to-child transmission in Toxoplasma gondii infection occurs only when the infection is acquired for the first time during pregnancy. Diag nosis of maternal infection and the newborn is achieved by a combination of serological tests, clinical features and ultrasound images. An early diagnosis of maternal infection allows treatment that offers a reduction both in transmission rate and risk of congenital damage. The aim of this expert consensus was to review the scientific literature which would enable an update of the clinical practice guideline of prevention, diagnosis and treatment of congenital toxoplasmosis in our country.

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.

Perfil dos casos de sífilis congênita no rio grande do norte: estudo de série temporal / Profile of Congenital Syphilis cases in Rio Grande do Norte State: a Temporal Series Study / El perfil de los casos de sífilis congénita en Rio Grande do Norte: Estudiode Serie Temporal

Objetivo:Analisar a incidência, a mortalidade e o perfil dos casos de sífilis congênita no Rio Grande do Norte entre 2014 e 2018. Metodologia:Trata-se de um estudo epidemiológico, quantitativo, ecológico, realizado com dados de sífilis congênita registrados no Sinan. Resultados:A taxa de incidência e mortalidade por sífilis congênita duplicaram no Estado no período analisado. A maioria das crianças foi diagnosticada com menos de 7 dias após o nascimento, sendo mais predominante em filhos de mães com idade entre 20 e 29 anos, com baixa escolaridade e pardas, que foram diagnosticadas com sífilis recente e que tiveram acesso ao pré-natal. A maioria teve o diagnóstico da sífilis materna durante o pré-natal, mas não realizou tratamento adequado e o parceiro não recebeu tratamento. Conclusões:Os achados apontam para necessidade de estratégias para qualificação da atenção pré-natal com intuito de evitar a transmissão vertical, especialmente nesses grupos mais susceptíveis e vulneráveis (AU).

Objective:To analyze the incidence, mortality, and profile of cases of congenital syphilis at the Rio Grande do Norte between 2014 and 2018. Methodology:This is an epidemiological, quantitative, ecological study conducted with data on congenital syphilis registered at Sinan. Results:The incidence and mortality from congenital syphilis doubled in Rio Grande do Norte State during the analyzed period. Most children were diagnosed less than seven days after birth, being more prevalent in children of mothers aged 20 to 29 years, with low education and mixed-race, diagnosed with recent syphilis, and who had access to prenatal care. Most were diagnosed with maternal syphilis during prenatal care but did not receive adequate treatment, and the partner did not receive treatment. Conclusions:The findings show the need for strategies for quality prenatal care to avoid vertical transmission, especially in these most susceptible and vulnerable groups (AU).

Prevention measures for vertical HIV transmission: monitoring infected pregnant women and exposed children / Medidas de prevenção para transmissão vertical do HIV: acompanhamento de gestantes infectadas e crianças expostas

Abstract Objectives: to present an analysis of the follow-up of exposed children and pregnant women living with HIV who are assisted in a reference public healthcare service of a Brazilian capital. Methods: this is a cross-sectional study with sociodemographic and clinical data obtainedfrom physical and electronic medical records of women living with HIV and exposed children, treated between 2000 and 2018, in a secondary healthcare service. For associations, the chi-square test at 5% significance was used. Results: the data about 183 pregnancies and 214 children from the capital or other municipalities in the state were analyzed. The women have low schooling, are brown or black, single, multiparous, diagnosed with HIV during prenatal care, with the start of follow-up from the third trimester of pregnancy and the use of prophylaxis during childbirth. As for children, the associations were significant for notification on SINAN, admission to the health service, use of prophylaxis indicating better monitoring for those who live in the state capital. Conclusions: the prevention measures recommended by the Ministry of Health, in general, were followed, but children and pregnant women who live in other cities were worse off than those ones in the capital. Unnotified cases were identified on SINAN. These issues may contribute to new cases of vertical transmission of HIV.

Resumo Objetivos: apresentar uma análise do acompanhamento de crianças expostas e gestantes vivendo com HIV atendidas em um serviço público de referência de uma capital brasileira. Métodos: trata-se de estudo transversal, com dados sociodemográficos e clínicos obtidos em prontuários físicos e eletrônicos mulheres vivendo com HIV e crianças expostas, atendidas entre 2000 a 2018 em um serviço de atenção secundária à saúde. Para as associações foi utilizado o teste qui-quadrado, com significância de 5%. Resultados: foram analisados dados de 183 gestações de 150 mulheres e 214 crianças expostas a infecção pelo HIV As mulheres possuíam baixa escolaridade, eram pardas ou pretas, solteiras, multíparas, com diagnóstico de HIV durante o pré-natal, com início do acompanhamento a partir do terceiro trimestre de gestação e uso de profilaxia durante o parto. Quanto às crianças, as associações foram significativas para notificação no SINAN, admissão no serviço de saúde, uso de profilaxia indicando melhor acompanhamento para aquelas que moravam na capital do estado. Conclusões: as medidas de prevenção recomendadas pelo Ministério da Saúde, em geral, foram seguidas, porém apresentaram pior cenário as crianças e gestantes que residiam em outros munícipios quando comparadas as da capital. Foram identificados casos não notificados no SINAN. Essas questões podem contribuir para novos casos de transmissão vertical do HIV.

Avaliação das oportunidades perdidas no controle da transmissão vertical do HIV em Rio Branco, Acre, Brasil / Evaluation of missed opportunities in the control of vertical HIV transmission in Rio Branco, Acre State, Brazil / Evaluación de las oportunidades perdidas en el control de la transmisión vertical del VIH en Río Branco, Acre, Brasil

Resumo: A transmissão vertical do HIV ainda representa um importante problema de saúde pública no mundo. O objetivo deste estudo foi verificar a transmissão vertical do HIV em Rio Branco, Acre, Brasil, e avaliar a possibilidade de eliminação. Foi realizado estudo transversal dos casos de HIV em gestante e longitudinal sobre a incidência da transmissão vertical do HIV na base populacional de gestantes residentes no Município de Rio Branco, no período de 2007-2015. As coortes de gestantes foram formadas por mulheres que tiveram filhos nascidos vivos, mortos ou abortos. Os dados foram obtidos do Sistema de Informação de Agravos de Notificação (SINAN), Sistema de Informações sobre Nascidos Vivos (SINASC), Sistema de Informação sobre Mortalidade (SIM) e Sistema de Informações Hospitalares (SIH). Foi realizado o relacionamento entre as bases de dados utilizando o software OpenRecLink. Foram calculadas as prevalências de HIV em gestante, a taxa de transmissão vertical e os principais fatores associados. A prevalência de HIV em gestante apresentou tendência de aumento, e a prevalência média foi de 0,18%, as variáveis estatisticamente associadas à ocorrência de HIV em gestantes foram idade materna ≥ 20 anos (p = 0,007), menor escolaridade (p = 0,054) e não ter companheiro (p = 0,001). A transmissão vertical foi de 6,9%. O uso de terapia antirretroviral (TARV) no pré-natal, mesmo entre as gestantes que já sabiam ser portadoras do vírus, foi menor que 90%. A realização de cesáreas eletivas ficou abaixo de 60%, e o uso de TARV no parto e pelo recém nascido nas primeiras 24 horas apresentou variações, dependendo do período em que o diagnóstico materno foi realizado. Embora as estratégias de eliminação da transmissão vertical do HIV estejam bem estabelecidas, os resultados deste estudo ainda apontam falhas importantes na cascata de cuidados das gestantes infectadas em Rio Branco.

Abstract: Vertical HIV transmission is still an important global public health problem. This study aimed to verify vertical HIV transmission in Rio Branco, Acre, Brazil, and to assess the possibility of its elimination. A cross-sectional study was conducted of HIV in pregnant women and a longitudinal study on the incidence of vertical HIV transmission in pregnant women living in the municipality (county) of Rio Branco in 2007-2015. The cohorts of pregnant women consisted of women who had liveborn children, stillbirths, or abortions. The data were obtained from the Brazilian Information System for Notificable Diseases (SINAN), Brazilian Information System on Live Births (SINASC), Brazilian Mortality Information System (SIM), and Brazilian Hospital Information Systems (SIH). Databases. Probabilistic database linkage was performed with the OpenRecLink software. The authors calculated the HIV prevalence rate in pregnant women, the vertical transmission rate, and the principal associated factors. HIV prevalence in pregnant women showed an upward trend, and the mean prevalence was 0.18%. Variables statistically associated with the occurrence of HIV in pregnant women were maternal age ≥ 20 years (p = 0.007), lower schooling (p = 0.054), and unmarried conjugal status/without partner (p = 0.001). Vertical HIV transmission was 6.9%. Use of antiretroviral therapy (ART) during prenatal care, even among pregnant women that already knew they were HIV-positive, was less than 90%. The elective cesarean rate was less than 60%, and the use of ART during delivery and by the newborn in the first 24 hours showed variations, depending on the period in which the maternal diagnosis was made. Although the strategies for the elimination of vertical HIV transmission are well established, this study's results point to important flaws in the cascade of care for HIV-infected pregnant women in Rio Branco.

Vertical transmission of maternal COVID-19 antibodies after CoronaVac vaccine: A case report

Abstract The use of coronavirus disease 2019 RNA vaccines in pregnant women led to reports on the first cases of newborns with antibodies to sudden acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a phenomenon that was unknown when using immunizations with inactivated viruses. Thus, this study aimed to report a case of passive anti-SARS-CoV-2 immunity in a newborn through immunoprophylaxis of a pregnant woman who received the CoronaVac® vaccine in the third trimester of pregnancy. Twenty-four hours after delivery, samples were collected from the newborn and screened by enzyme immunoassays, which revealed antibodies to SARS-CoV-2.

Resumen Este artículo aborda las hepatitis virales, tema que hace parte del Protocolo Clínico y Directrices Terapéuticas para la Atención Integral a Personas con Infecciones de Transmisión Sexual y más precisamente de los Protocolos Clínicos y Guías Terapéuticas para Hepatitis B, Hepatitis C y Coinfecciones, publicados por el Ministerio de Salud. Además del amplio espectro de deterioro de la salud, los virus de las hepatitis A, B y C presentan diferentes formas de transmisión, como parenteral, sexual, vertical u oral. Entre las estrategias sugeridas para el control de las hepatitis virales, están las medidas conductuales, el diagnóstico ampliado, la vacunación precoz contra los virus de las hepatitis A y B y el acceso facilitado a los recursos terapéuticos disponibles. Considerando la transmisión vertical de los virus de la hepatitis B y C, la identificación de embarazadas portadoras crónicas de estos virus es importante estrategia de salud perinatal, indicando quiénes pueden beneficiarse de las intervenciones profilácticas.

Effects of Human Immunodeficiency Virus-positive Mothers Receiving Antiretroviral Therapy to Prevent Mother-to-child Transmission on the Growth and Development of 18-month-old Children in Lingshan County of Guangxi / 中国医学科学院学报

Objective To evaluate the effects of antiretroviral therapy(ART)for the prevention of mother-to-child transmission(PMTCT)of acquired immune deficiency syndrome(AIDS)on the growth and development of 18-month-old children born by human immunodeficiency virus(HIV)-positive pregnant women in Lingshan County,Guangxi Zhuang Autonomous Region,and provide scientific evidence for improving the ART medication plan for PMTCT.Methods Lingshan County,ranking the first in the HIV-epidemic counties of Guangxi,was selected as the research site.According to the design of retrospective case-control study,we assigned all the subjects into the case group and the control group:(1)The case group included the HIV-positive pregnant women who had received ART for PMTCT and their HIV-negative infants in Lingshan County from 2010 to 2017.The historical cards and PMTCT data of them were collected from the national PMTCT database.(2)The control group included the healthy pregnant women and their healthy babies born in the Lingshan Maternity and Infant Hospital in 2017,and the children's growth and development data were collected.The stunted growth in children was defined as at least one of the three main indicators of body height,body weight,and head circumference below the normal range.Results The number of HIV-positive mothers and their infants in the case group was 391 and 368,respectively,and 87.21%(341/391)and 95.38%(351/368)of mothers and infants respectively received ART medication.The HIV positive rate,mortality rate,and mother-to-child transmission rate of 18-month-old children were 1.36%(5/368),4.35%(16/368),and 2.01%(5/249),respectively.The incidence of stunted growth of 18-month-old children in the case group and the control group was 42.12%(155/368)and 23.06%(101/438),respectively,with significant difference(

Vertical transmission of hepatitis B virus: propositions and future directions / 中华医学杂志(英文版)

Chronic hepatitis B virus (HBV) infection due to vertical transmission remains a critical concern with regards to eliminating HBV infection. Implementation of hepatitis B vaccine, the foundation to prevent perinatal and horizontal transmission, has reduced the prevalence of HBV by >80%. In countries where the hepatitis B immune globulin (HBIG) is available, such as China and the United States, the administration of HBIG and hepatitis B vaccine to the infants of mothers who are positive for hepatitis B surface antigen has become a standard practice and is effective in preventing vertical transmission. Accumulating evidence on the efficacy and safety of antiviral prophylaxis during pregnancy indicates the probability of attaining the goal of the World Health Organization to eliminate hepatitis by 2030. In this review, we discuss the transmission routes, diagnostic criteria, and preventive strategies for vertical transmission. A preventive program that includes screening before pregnancy, antiviral prophylaxis during pregnancy, and postpartum immunoprophylaxis provides "perfect strategies" to eliminate vertical transmission. However, there is still a notable gap between "perfect strategies" and real-world application, including insufficient coverage of timely birth dose vaccine and the efficacy and necessity of HBIG, especially in mothers who are negative for hepatitis B envelope antigen. In particular, there is a clear need for a comprehensive long-term safety profile of antiviral prophylaxis. Therefore, feasible and cost-effective preventive strategies need to be determined across regions. Access also needs to be scaled up to meet the demands for prophylaxis and prevalence targets.
