Protection level of anti­hepatitis B vaccine and immunoglobulin in a pediatric Cameroonian population

Despite the availability for nearly twenty years of an effective vaccine, hepatitis B remains one of the most frequent viral diseases throughout the world. Mother to child transmission is one of the primary routes of transmission in children. To assess the vaccine response in children born to HBV infected mothers. HBsAg positive consenting mothers registered in the antenatal care (ANC) service database of Centre Hospitalier Dominicain St Martin de Porres, Yaounde were enrolled with their children. Socio demographic char acteristics were collected using a tested questionnaire. The 5 markers of hepatitis B were tested and the quantification of anti HBsAg antibodies was done by indirect ELISA method. The data collected was analyzed using Microsoft excel and Epi info softwares. Out of 5,996 women registered, 143 were identified as HBsAg positive (2.38% prevalence) and none was HBeAg positive. Of these 143 HBsAg positive women, 50 were enrolled in the study. Of the 50 positive mothers, 78 children were included with a mean age ± standard deviation of 2.33±2.86 years. No child was infected with HBV, but all have been exposed to the virus (HBeAb positive). Overall 64 (82.05%) received at birth both anti HBs immunoglobulin (HBIG) and a dose of vaccine, while 14 (17.95%) received only the birth dose of vaccine. 72 (92.31%) children received all three recommended doses of vaccine. Vaccine responders were 62.82% (above 10 IU/ml), while 37.18% of children were non responders; representing a higher risk group if not boosted. The coverage of the anti HBV vaccine in children in this study was 92.31%. The protection level of 62.82% is below the 95% recommended rate by WHO. The factors sustaining this suboptimal protection should be investigated

Adherence to ART drugs among HIV-positive pregnant women at selected hospitals of East Ethiopia

Background: Substance abuse among Human Immune Deficiency Virus-positive patients causes depression, carelessness, and anxiety, which in common results in a decrease in adherence to antiretroviral treatment. The purpose of the study is to assess the prevalence of substance abuse and its association with adherence to ART drugs. Methods: The current study was conducted at three hospitals (Hiwot Fana Comprehensive University Hospital, Dillchora Hospital, and Jugal Hospital) located in East Ethiopia. Bivariate and multivariate logistic regression analysis was used to identify the association of independent variables with the dependent variables. Results: In this study, 119 HIV-positive pregnant patients were included. While 74.8% of the patients were adherent to their medication, the remaining 25.2% were nonadherent. The major reasons for nonadherence to ART medications prescribed were getting better (73.3%) and finishing medication (16.7%). Moreover, 96 (80.7%) respondents abused alcohol while 36 (30.3%) and 75 (35.6%) abused opioids and cigarette smoking, respectively. Mothers who abused alcohol were 38.1 times more likely to be nonadherent to ART medications for PMTCT [AOR = 38.1% CI: 21.47­56.54] compared to their counterparts. Additionally, mothers who abuse opioids were 19 times more likely to be nonadherent to ART treatment medication [AOR = 19, 95% CI: 2.46­ 19.46] than their counterparts. Furthermore, mothers who smoked cigarettes were 43.1 more likely to be nonadherent [AOR = 43.19, 95% CI: 8.42­187.84] than nonsmokers. Unemployment was also found to be associated with nonadherence to ART medication to PMTCT of HIV [AOR = 5.4, 95% CI: 2.8­5.7]. Smoking of marijuana/cannabis/hashish was not significantly associated with nonadherence to ART [AOR = 0.22, 95% CI: 0.084­0.355]. Conclusion: Abuse of alcohol, cigarette smoking, abuse of opioids, and joblessness were found to be significantly associated with nonadherence to ART medications prescribed to PMCT of HIV. Wheareas, smoking of marijuana/cannabis/hashish was not significantly associated with nonadherence to ART medications.

Midwives' perceptions of and attitudes towards prevention of mother-to-child-transmission of HIV

Background: Prevention of mother-to-child transmission (PMTCT) of HIV services has become an integral part of antenatal services. Prevention of mother-to-child transmission was introduced in all the regions of Ghana, but mother-to-child transmission (MTCT) continued to increase. Objectives: To explore and describe midwives' perceptions and attitudes towards PMTCT of HIV services. Method: Quantitative research approach and descriptive cross-sectional design were used. The population includes all midwives between the ages of 21 and 60 years who work in antenatal care (ANC) clinics in 11 district hospitals in the Central Region of Ghana where the study was conducted. Forty-eight midwives were interviewed using a census sample process. Data were analysed using the Statistical Package for the Social Sciences version 21. Correlation analysis was performed to find the relationships between the attitudes and the perceptions of the midwives on PMTCT of HIV services. Results: Seventy percent of midwives had positive perceptions of PMTCT of HIV services and 85% had positive attitudes towards the provision of PMTCT of HIV services. Midwives were screening all pregnant women who visited the ANCs and referring those who tested positive to other institutions where they can be monitored. Some of the concerns considered were views on retesting HIV-infected pregnant women throughout their pregnancy. There was a positive correlation between attitudes and perceptions of midwives on PMTCT of HIV services. Conclusion: Midwives had positive perceptions and positive attitudes towards the PMTCT of HIV services that they were providing to antenatal attendees. Also, as the attitudes of the midwives towards PMTCT of HIV services improved, their perceptions of PMTCT services also improved. Contribution: Decentralisation of PMTCT of HIV services to community-based health facilities is appropriate to enable sub-district health facilities to test for HIV and provide counselling services to pregnant women.

Effect analysis of combined immunological blockade mother-to-child transmission of hepatitis B virus in Hainan Province from 2015 to 2020 / 中国热带医学

@#Abstract: Objective　To analyze the influencing factors of mother-to-child transmission of hepatitis B virus after combined immunological blockade, and to evaluate the effect of mother-to-child blockade, and to provide a basis for health policies and health interventions for preventing mother-to-child blockade of hepatitis B virus. Methods A total of 11 363 pairs of HBsAg positive pregnant women and their infants aged 7-12 months in Hainan Province from 2015 to 2020 were included in the study. The general situation, the situation of health care and delivery in this pregnancy and perinatal period, the detection of hepatitis B markers, the situation of antiviral therapy, the general situation of mother and infant during delivery and the implementation of blockade measures for mother-to-child transmission of hepatitis B were collected and analyzed. Results Among the 11 363 pairs of HBsAg positive pregnant women and their infants delivered in hospitals in Hainan province from 2015 to 2020, the positive rate of HBsAg in children at 7-12 months after birth was 1.47 %, and the difference in HBsAg positive rate of infants born in different years was not statistically significant (P>0.05). There were no significant differences in the positive rate of HBsAg among children born to pregnant women with different nationalities, educational levels, occupations, delivery modes, delivery places, obstetric operations and perineal laceration, abnormal perinatal period, children with different genders and premature delivery and perinatal (all P<0.05). There was significant difference in HBsAg positive rate among infants born to pregnant women of different ages, the positive rate of HBsAg of infants born to young pregnant women was higher than that of older pregnant women (P<0.05). The rate of antiviral therapy was low in HBeAg positive pregnant women, and the positive rate of HBsAg in their infants was 2.54%, which was higher than 0.83% in HBeAg negative pregnant women (P<0.05). Conclusions Combined immunological blockade with hepatitis B vaccine and hepatitis B immunoglobulin can effectively prevent the mother-to-child transmission of HBV. HBsAg-positive women can give birth at the right age, and HBeAg-positive pregnant women can be treated with antiviral therapy to block mother-to-child transmission, providing the important basis for the formulation of hepatitis B prevention and control strategies and measures.

Birth weight of infants born to pregnant women living with human immunodeficiency virus and its associated factors / 中华传染病杂志

Objective:To investigate the birth weight (BW) of infants born to pregnant women living with human immunodeficiency virus (HIV) and its associated factors, and to provide more evidence for the prevention of mother-to-child transmission (PMTCT) in China.Methods:This study was a retrospective cohort study. Between January 2004 and December 2021, pregnant women living with HIV and their infants in Hubei Province were recruited and followed up, and clinical data were collected through hospital medical records and HIV/acquired immunodeficiency syndrome comprehensive response information management system. The multivariable linear regression was performed on the collected data to investigate associated influencing factors of BW.Results:In total, 531 pregnant women living with HIV (581 pregnancies) and 581 infants were enrolled. Of the 581 infants, 36 were HIV-positive, with a PMTCT rate of 6.2%. The mean BW of the infants was (3 075.0±470.2) gram. Protease inhibitor (PI) based-anti-retroviral therapy (ART) ( β=-0.1, 95% confidence interval ( CI)-188.2 to -37.1, P=0.004), ART in the first trimester( β=-0.1, 95% CI -201.9 to -65.5, P<0.001), infant HIV infection ( β=-0.1, 95% CI -310.4 to -68.2, P=0.002), hepatitis C virus infection ( β=0.1, 95% CI 71.2 to 410.4, P=0.005) and gestational age ( β=0.6, 95% CI 155.9 to 191.5, P<0.001) were associated with decreased BW. Conclusions:While improving the effectiveness of PMTCT for HIV, more attention should be paid to pregnant women who received ART in the first trimester and PI-based ART for preventing lower BW and improving maternal and infantile health.

Missed opportunities in preventing mother-to-child transmission of syphilis in the indigenous population in central Brazil / Oportunidades perdidas na prevenção da transmissão vertical da sífilis na população indígena do Brasil central

Abstract Objectives: to estimate the detection rate of syphilis in pregnant women, the occurrence of congenital syphilis, and the rate of mother-to-child transmission of syphilis, in addition to analyzing missed opportunities in the prevention of mother-to-child transmission in the indigenous population. Methods: descriptive study of cases of pregnant indigenous women with syphilis resulting or not in a case of congenital syphilis. The data were obtained from the Sistema de Informação de Agravos de Notificação (Information System of Notifable Diseases), the records of the Infecções Sexualmente Transmissíveis do Distrito Sanitário Especial Indígena (Sexually Transmitted Infections in the Special Indigenous Health District), and the medical records of pregnant indigenous women in 2015. The database and the calculation of syphilis rates in pregnant women, congenital syphilis, and mother-to-child transmission were carried out. Data on prenatal, diagnosis and treatment of syphilis during pregnancy were collected from the medical records. Results: the detection rate of syphilis in pregnant women reached 35.2/1,000 live births (LB), the occurrence of congenital syphilis encompassed 15.7/1.000 LB, and the rate of mother-to-child transmission was 44.8%. Six (24%) pregnant women started prenatal care in the first trimester and seven (28%) attended seven or more consultations. The diagnosis of syphilis was late and only nine (36%) women were properly treated. Conclusions: failures in the diagnosis and the adequate treatment of pregnant women with syphilis compromised the prevention of mother-to-child transmission of the disease.

Evidenciou-se que seis (24%) gestantes iniciaram o pré-natal no primeiro trimestre e sete (28%) realizaram sete ou mais consultas. O diagnóstico de sífilis foi tardio e apenas nove (36%) realizaram adequadamente o tratamento. Conclusões: falhas no diagnóstico e no tratamento adequado de gestantes com sífilis comprometeram a prevenção da transmissão vertical da doença.

Factors influencing utilization of modern family planning services by persons living with Human Immunodeficiency Virus at Luwero Hospital, Uganda

Introduction: The use of modern family planning methods is key for achieving the prevention of unintended pregnancies among women living with HIV, in the prevention of Mother-to-child transmission (PMTCT) package. The purpose of this study was to examine the factors influencing the utilization of modern family planning services by persons living with HIV at Luwero Hospital, Uganda. Methods: The study was conducted among 210 persons living with HIV attending the ART clinic and was based on cross-sectional descriptive and analytical design. Sampling was by simple random techniques. Data was collected using researcher-administered questionnaires. Results: The uptake of Modern FP services is low (36.7%) among persons living with HIV. It was attributed to client-related factors such as being married [AOR: 2.2, 95% CI [1.123-4.140], p = 0.038]) and other factors. These are; religious views discouraging use of modern FP (p= 0.034), negative side effects (AOR: 1.8, 95% CI [0.043-1.968], p = 0.044) and services being unfriendly for persons living with HIV (p=0.000]). Conclusions: Despite the presence of modern family planning services, uptake among persons living with HIV is low. Poor utilization is a recipe for unintended pregnancy and thus jeopardizes efforts in the elimination of mother-to-child transmission of HIV

Advances in the prevention of mother-to-child transmission of hepatitis B virus / 中华围产医学杂志

Mother-to-child transmission (MTCT) of hepatitis B virus (HBV) represents the most common mode by which children acquire HBV infection. For pregnant women with high viral load and positive hepatitis B e antigen (HBeAg), antiviral therapy during late pregnancy combined with timely and standardized inoculation of neonatal hepatitis B immunoglobulin and hepatitis B vaccine can minimize the possibility of MTCT of HBV. This review focuses on using and withdrawing antiviral drugs during pregnancy, managing postpartum hepatitis, and breastfeeding issues to further optimize the combined immunization and antiviral treatment strategies and seek the optimal solution to preventing MTCT of HBV.

Effects of different feeding patterns on mother-to-child transmission of HBV infections in pregnant women with high viral loads after antiviral medication during pregnancy: A prospective cohort study / 中华围产医学杂志

Objective:To study the influence of different feeding patterns on mother-to-child transmission (MTCT) of hepatitis B virus (HBV) in pregnant women with high viral loads who received antiviral medication during pregnancy to the day of delivery.Methods:This prospective cohort study was conducted in Beijing You'an Hospital. From January 1, 2019, to March 31, 2020, and 574 pregnant women with positive hepatitis B surface antigen (HBsAg) and HBV DNA>2×10 5 IU/ml were enrolled. All participants received tenofovir, telbivudine, lamivudine, or propofol tenofovir from 24-28 weeks of gestation and discontinued on the day of delivery, and their neonates were postnatally given routine passive-active immunoprophylaxis. Based on the feeding patterns, the subjects were divided into three groups: breastfeeding ( n=257), bottle-feeding ( n=241) and mixed feeding groups ( n=76). The follow-up data were obtained from liver functions and HBV DNA level of the mothers at 6-8 weeks postpartum and HBV serological markers of infants at 7-12 months. One-way ANOVA, Student-Newman-Keuls, Chi-square test or Fisher exact test, and repeated measures ANOVA were used to analyze the data. Results:The average maternal HBV DNA levels before antiviral treatment did not differ significantly between the three groups [(7.90±0.67), (7.82±0.70), (7.83±0.70) log 10 IU/ml, F=0.912, P>0.05]. HBV DNA level before delivery in the mixed feeding group was slightly lower than that in the breastfeeding and bottle-feeding group [(3.87 ±1.08) vs (4.21±1.17) and (4.30±1.28) log 10 IU/ml, q= 3.052 and 3.831, both P<0.05], while the comparison between the latter two groups showed no significant differences ( P>0.05). After delivery, HBV DNA level in the bottle-feeding group was slightly lower than that in the breastfeeding group [(7.42±0.93) vs (7.69±0.90) log 10 IU/ml, q=4.583, P<0.05]. Among 580 infants (including six pairs of twins), only one bottle-fed infant (0.4%, 1/243) was infected with HBV through MTCT, and none in the breastfeeding or mixed feeding group ( P=0.553). Conclusions:For pregnant women with high viral loads of HBV who have received antiviral medication during pregnancy, although HBV DNA level will rebound after discontinuation upon delivery, breastfeeding is recommended considering it does not increase the risk of MTCT.

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(

Management algorithm for prevention of mother-to-child transmission of hepatitis B virus (2021) / 中华肝脏病杂志

The World Health Organization (WHO) has set the goal of eliminating viral hepatitis as a threat to public health by 2030. Blocking mother-to-child transmission (MTCT) of hepatitis B virus (HBV) is the key step for eliminating viral hepatitis, at the same time, it is the hotspot in the field of hepatitis B prevention and control as well. The China Foundation of Hepatitis Prevention and Control (CFHPC) organized a team of specialists to develop an algorithm for preventing MTCT of HBV, based on the most recent hepatitis B guidelines and the latest evidence. The algorithm covers 10 continuous steps from pregnant management to follow-up postpartum. Among the 10 steps, screening, antiviral therapy during pregnancy, and infant's immunization are the core components in the algorithm.

Consenso de la infección por VIH en embarazadas, niños, adolescentes

La infección por VIH sigue impactando de manera significativa a embarazadas, niños y adolescentes. En las embarazadas, es necesario hacer la prueba de VIH en la primera consulta prenatal o al primer contacto con el sistema de salud, y luego repetir en el tercer trimestre, preferiblemente antes de las 36 semanas de gestación, en caso de que el resultado sea negativo inicialmente; mientras que el diagnóstico en pediatría se basa en la realización de pruebas virológicas (PCR DNA o RNA) en niños menores de 18 meses y de pruebas serológicas en mayores de 18 meses, con seguimientos periódicos a fin de evaluar la evolución clínica, adherencia y posible toxicidad medicamentosa. En ambas poblaciones, es necesario considerar, previo al inicio del TARV la realización del test de resistencia a fin de orientar la terapéutica, con posteriores controles de carga viral plasmática (CVP) y contaje de linfocitos T CD4. La utilización del TARV implica resaltar un objetivo epidemiológico, pues su uso se asocia con riesgo menor de transmisión maternoinfantil. En este consenso se busca disponer de recomendaciones en relación con el diagnóstico y TARV de embarazadas, niños y adolescentes con infección por VIH, las cuales puedan servir de orientación al clínico especialista en el área, dada la complejidad y avances constantes en la investigación de las distintas familias de antirretrovirales, así como su eficacia, toxicidad, interacciones medicamentosas, aparición de resistencias, tropismo y al adecuado manejo en diversas situaciones especiales.

HIV infection continues to significantly impact pregnant women, children and adolescents. In pregnant women, it is necessary to do the HIV test at the first prenatal visit or at the first contact with the health system, and then repeat in the third trimester, preferably before 36 weeks of gestation, in case the result is negative. initially; while the diagnosis in pediatrics is based on the performance of virological tests (DNA or RNA PCR) in children younger than 18 months and serological tests in those older than 18 months, with periodic follow-ups in order to evaluate the clinical evolution, adherence and possible drug toxicity. In both populations, it is necessary to consider, prior to the start of ART, the performance of the resistance test in order to guide therapy, with subsequent controls of plasma viral load (CVP) and CD4 T lymphocyte count. The use of ART implies highlighting an epidemiological objective, since its use is associated with a lower risk of mother-to-child transmission. This consensus seeks to have recommendations in relation to the diagnosis and ART of pregnant women, children and adolescents with HIV infection, which can serve as guidance to the clinical specialist in the area, given the complexity and constant advances in the investigation of the different families of antiretrovirals, as well as their efficacy, toxicity, drug interactions, emergence of resistance, tropism and proper management in various special situations.

Background: To study the effect of human immunodeficiency virus (HIV) infection on pregnancy outcomes and new born as mother to child transmission of HIV is a major route on new infections in children and compare it with HIV uninfected pregnancies.Methods: Prospective comparative study conducted on 40 HIV seropositive and 40 HIV seronegative pregnant women attending ANC and delivering in the department of obstetrics and gynecology, S. M. S. Medical College, Jaipur, Rajasthan, India.Results: CD4 count had no effect on birth weight of baby or term of delivery. HIV seropositive pregnancies were more prone to IUD, still birth and preterm birth (p=0.029). Mother to child transmission was 2.7%.Conclusions: HIV infection increases the risk of adverse foetal outcome in terms of intrauterine demise, still birth and preterm labour.

Epidemiological characteristics and interruption of 228 HBV positive pregnant women / 公共卫生与预防医学

Objective To investigate the epidemiological characteristics and interruption of 228 hepatitis B virus (HBV) positive pregnant women, and to provide more references for clinical education and treatment. Methods A total of 228 chronic HBV pregnant women underwent maternal-neonatal transmission blocking treatment in Third Affiliated Hospital of Sun Yat-sen University from January 2015 to April 2019 were enrolled. Self-designed follow-up questionnaires were used to collect pregnant women's data. Then the relationship of epidemiological characteristics and HBV-DNA load levels with the genotype, hepatitis B e antigen (HBeAg), and alanine aminotransferase (ALT) was analyzed, moreover, the prevention of mother-to-child transmission was also analyzed. Results A total of 228 HBV-positive pregnant women were mainly over 30 years old, with a family history of liver disease, low education level (

Comments on 2019 Chinese practice guideline for the prevention and treatment of hepatitis B virus mother-to-child transmission / 中华肝脏病杂志

Recently, the Society of Infectious Diseases of Chinese Medical Association and Chinese GRADE Center jointly released the "2019 Chinese practice guideline for the prevention and treatment of hepatitis B virus mother-to-child transmission" . We concerned several issues in the Guideline, including the improper citation of some references, no recommendations for some key strategies for the prevention of hepatitis B virus mother-to-child transmission, insufficient or even lack of evidence for some recommendations and others. Based on the principle of academic contention, we present in this article our comments on the Guideline to discuss these issues with the Guideline’s authors and readers.

Maternal breast feeding safety of hepatitis B virus carrying parturient women with hepatitis B surface antigen and hepatitis B e antigen double positive / 中华传染病杂志

Objective@#To explore hepatitis B virus (HBV) infection rate of breast feeding to newborn babies of HBV carrying parturient women with hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) double positive.@*Methods@#A prospective cohort study was conducted to include HBsAg and HBeAg double-positive HBV carrying parturient women and their babies born from February 2016 to May 2018 at the Women′s Hospital, Zhejiang University School of Medicine, and 323 parturient women and 323 babies were enrolled. The babies were divided into breast feeding group and artificial feeding group. Chemiluminescence immunoassay and polymerase chain reaction-fluorescent probe method were used to detect the positive rates of serum HBV markers and HBV DNA levels in the newborns <24 h and seven-month-old age, respectively. The statistical method was performed using χ2 test.@*Results@#A total of 297 parturient women were finally included for the analysis, including 149 in the breast feeding group and 148 in the artificial feeding group. There were no significant differences in the positive rates of HBsAg, hepatitis B surface antibody (anti-HBs), HBeAg and HBV DNA>100 IU/mL between the two groups at birth <24 h and seven months of age (all P>0.05). The positive rate of anti-HBs in newborns in the breast feeding group at birth <24 h was 58.39%(87/149), which was lower than 95.97%(143/149) at seven months of age. The HBeAg-positive group was 65.10%(97/149) at birth <24 h in the breast feeding group, which was higher than 13.42%(20/149) at seven months of age. The differences were both statistically significant (χ2=59.75 and 40.49, respectively, both P<0.01). The positive rates of HBsAg and HBV DNA>100 IU/mL in newborns in the breast feeding group were 2.01%(3/149) and 2.68%(4/149) at birth <24 h, respectively, and those at seven months were 2.68%(4/149) and 2.68%(4/149), respectively. There were no significant differences between the two time points (both P>0.05). In the artificial feeding group, the positive rate of anti-HBs in newborns was 47.97%(71/148) at birth <24 h, which was lower than 95.94% (142/148) at seven months of age. The positive rate of HBeAg in the artificial feeding group was 55.41%(82/148) in newborns at birth <24 h, which was higher than 19.59%(29/148) at seven months of age. The differences were statistically significant (χ2=85.37 and 39.84, respectively, both P<0.01). The positive rates of HBsAg and HBV DNA>100 IU/mL in newborns in the artificial feeding group at birth <24 h were 4.73%(7/148) and 1.35%(2/148), respectively, and those at seven months were 1.35%(2/148) and 1.35%(2/148), respectively. There were no significant differences between the two time points (both P>0.05).@*Conclusions@#Breast feeding is not a decisive factor for the risk of vertical transmission in HBsAg and HBeAg double-positive HBV carriers. It is recommended that such women could breastfeed under formal precautions.
