Abstract
Background Vertical mother-to-child transmission (MTCT) of the hepatitis B virus (HBV) remains an important issue. Timely administration of hepatitis B immunoglobulin (HBIG) and of the HBV vaccine is effective in preventing MTCT in infants born to HBV-infected mothers. However, HBIG is often not easily available in low-income countries or regions. Methods We compared in a retrospective cohort study the HBV vaccine efficacy alone and in combination with HBIG in preventing vertical MTCT in infants born to HBeAg-negative carrier mothers in Jiangsu province, China. Based on the administration of the HBV vaccine and HBIG shortly after birth, children were divided into two groups: Group 1, administration of the HBV vaccine alone, and Group 2, concurrent use of HBIG and of the HBV vaccine. Results A total of 620 infants born to HBeAg-negative carrier mothers were enrolled into this study. Group 1 included 195 children who had received the HBV vaccine alone after birth, and Group 2, 425 children who had received both HBIG and the HBV vaccine. Children were followed up to the age of 68 and 42 months, respectively. MTCT of HBV occurred in 0% (0/195) in Group 1 (HBV vaccine alone) and 0% (0/425) in Group 2 (HBV vaccine and HBIG) (p = 1.00). Conclusion In this retrospective cohort study, we found that HBV vaccination alone shortly after birth was effective in preventing MTCT of HBV in infants born to HBeAg-negative carrier mothers.

Comparative efficacy and safety of pharmacologic interventions to prevent mother-to-child transmission of hepatitis B virus: a systematic review and network meta-analysis. Am J Obstet Gynecol 2022; 227:163-172. [PMID: 35263648 DOI: 10.1016/j.ajog.2022.02.042] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2021] [Revised: 02/12/2022] [Accepted: 02/23/2022] [Indexed: 11/01/2022]
Abstract
OBJECTIVE This study investigated the efficacy and safety of pharmacologic interventions to prevent vertical transmission of the hepatitis B virus. DATA SOURCES Medline, Cochrane, and Scopus databases were searched up to October 28, 2020. STUDY ELIGIBILITY CRITERIA All randomized controlled trials reporting vertical hepatitis B virus transmission with pharmacologic intervention were included. METHODS Risk of bias was assessed using the Cochrane Risk-of-Bias tool, version 2. Treatment efficacy was estimated using stratified network meta-analysis on the basis of maternal hepatitis B envelope antigen status. RESULTS Nineteen studies were included for mothers positive for hepatitis B surface and envelope antigens. Pooling indicated that a combination of hepatitis B vaccination and hepatitis B immunoglobulin in infants significantly reduced transmission risk compared with vaccination alone, with a risk ratio of 0.52 (95% confidence interval; 0.30-0.91). Only the addition of maternal tenofovir disoproxil fumarate, but not telbivudine, lamivudine, or maternal hepatitis B immunoglobulin further reduced transmission risk compared with a combination of hepatitis B vaccination and hepatitis B immunoglobulin in infants, with a pooled risk ratio of 0.10 (0.03-0.35). Twelve studies conducted in mothers with hepatitis B surface antigen positivity and mixed, unknown, or negative hepatitis B envelope antigen status provided limited evidence to suggest that maternal hepatitis B immunoglobulin combined with hepatitis B vaccination and immunoglobulin in infants was the likely best treatment, but this failed to reach statistical significance compared with a combination of hepatitis B vaccination and immunoglobulin in infants. Similarly, infant hepatitis B immunoglobulin, added to vaccination, likely provides additional benefit but failed to reach statistical significance. CONCLUSION A combination of hepatitis B vaccination and immunoglobulin in infants is the cornerstone for prevention of vertical transmission for mothers positive for both hepatitis B surface and envelope antigens. The addition of maternal tenofovir to this infant combination regimen was considered the likely most effective treatment. For infants of mothers with hepatitis B surface antigen positivity and mixed, unknown, or negative hepatitis B envelop antigen status, no additional agents provided further benefit beyond hepatitis B vaccination alone.

Abstract
Occult hepatitis B virus (HBV) infection (OBI) has been observed among infants born to hepatitis B surface antigen (HBsAg)-positive mothers despite successful immunoprophylaxis. This study enrolled 549 infants [349 infants received a 10μg/dose of hepatitis B vaccine (HepB), and 200 infants received 20μg/dose HepB] born to HBsAg-positive mothers with HBV DNA load >6log10IU/mL. The anti-HBs levels in the 10μg group were significantly lower than that in the 20μg group both at 7 [652.48 (564.05-754.82) vs. 1541.72 (1268.69-1873.51) mIU/mL, P<0.001] and 12 months old [257.44 (220.29-300.88) vs. 1073.41 (839.27-1372.78) mIU/mL, P<0.001]. The OBI incidence in the 10μg group was significantly higher than that in the 20μg group at both 7 [21.55% (25/116) vs. 7.56% (9/119), P=0.002] and 12 months old [17.07% (14/82) vs. 6.90% (6/87), P=0.041]. OBI incidence in infants with anti-HBs levels <100mIU/mL was higher than that of those with anti-HBs ≥100mIU/mL [35.71% (5/14) vs. 13.12% (29/221), P=0.036]. This study showed that increasing the immunisation dose from 10μg to 20μg significantly improved anti-HBs levels and decreased OBI incidence in infants with a high maternal viral load. We recommend 20μg HepB to treat this high-risk population.

Abstract
INTRODUCTION Hepatitis B is a major preventable cause of morbidity and mortality from chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma. We aimed to evaluate the performance and outcomes of the Korean Perinatal Hepatitis B Prevention Programme (PHBPP) and to investigate the impact of the current post-exposure immunoprophylaxis protocol. METHODS A retrospective cohort study was performed based on electronic data registry of infants born to hepatitis B virus (HBV)-infected mothers between July 2002 and 2013. RESULTS During the study period, 159,983 Korean infants were registered with the PHBPP, with an overall programme coverage of 92.8%. Despite receiving timely post-exposure immunoprophylaxis, 8.6% of infants born to mothers aged <25 years and hepatitis B e antigen (HBeAg)-positive, and 0.7% of infants born to mothers aged ≥25 years and HBeAg-negative were infected. An estimated 14,123 infants were directly protected from perinatal HBV transmission by the PHBPP during the 11.5-year period, at a cost of 1157 US dollars per case averted. The incidence of paediatric hepatocellular carcinoma declined dramatically during the period. CONCLUSIONS A substantial number of infants have been prevented from hepatitis B since the PHBPP was launched in the Republic of Korea. Continued efforts to promote the programme, an integrated approach to maximising its coverage, a risk-stratified strategy, and innovations in logistics could further reduce perinatal HBV transmission.

Abstract
Vaccination against hepatitis B is the most effective strategy to control HBV infection. The first licensed hepatitis B vaccine was developed by the purification of hepatitis B surface antigen (HBsAg) from plasma of asymptomatic HBsAg carriers. Then, the recombinant DNA technology enabled the development of recombinant hepatitis B vaccine. A series of three doses vaccine can elicit long-term protection more than 30 y. Concurrent use of hepatitis B immunoglobulin and hepatitis B vaccine has substantially reduced the mother-to-child transmission of HBV, nearly zero infection in children of carrier mother with negative hepatitis B e antigen (HBeAg) and 5-10% infection in children of HBeAg-positive mothers. By the end of 2018, 189 countries adopted universal hepatitis B vaccination program, which has dramatically reduced the global prevalence of HBsAg in children <5 y of age, from 4.7% in the prevaccine era to 1.3% in 2015. However, the implementation of universal hepatitis B vaccination in some regions is suboptimal and timely birth dose vaccine is not routinely administered in more than half of newborn infants. Optimal worldwide universal hepatitis B vaccination requires more efforts to overcome the social and economic challenges.

Abstract
BACKGROUND Hepatitis B (HBV) transmission may result from in utero transmission. We aimed to determine the correlation between maternal serum and umbilical cord blood HBV DNA levels in infants delivered by chronic HBV-infected mothers and to describe the effect of cord blood viremia on vertical transmission. METHODS A prospective cohort of 92 chronic HBV-infected mother-and-child pairs recruited over three years was analyzed. Maternal and cord blood were tested for HBV DNA by real-time PCR. Standard immunoprophylaxis with both active and passive immunization was administered to all infants. Serological testing was performed on all infants at 9 months of age. RESULTS Moderate positive correlation of the maternal HBV DNA with cord blood HBV DNA was demonstrated (r2 = 0.521, p = <0.001). HBeAg +ve mothers were younger with higher HBV and cord viremia. At 9 months of age, one infant was infected. Infants delivered by HBeAg positive mothers and mothers with high HBV DNA of more than 6 LOG IU/mL (1 x 106 IU/mL) have increased relative risk of cord blood viremia. CONCLUSIONS Maternal HBV DNA and presence of HBeAg were positively correlated to cord blood HBV DNA in infants delivered by chronic HBV-infected mothers. Our data suggest that reducing maternal viremia during the antenatal period may help to reduce cord blood viremia.

Abstract
OBJECTIVES To study the frequency of vertically acquired occult hepatitis B virus (HBV) infection (OBI). METHODS We investigated 44 children born to hepatitis B surface antigen (HBsAg) positive mothers. They received HBV vaccine directly after birth and at 2, 6 and 52 weeks of age; eight with HBeAg-positive mothers also received hepatitis B immunoglobulin (HBIG). HBV DNA was analyzed in blood collected at 6 weeks and 12 months of age, and HBV antibodies at 12 and 18 months of age. RESULTS HBV DNA, but not HBsAg or anti-HBc, was detected at 12 months of age in three children. The viral sequences were almost identical with HBV DNA from their mothers who all were HBeAg-positive and had received tenofovir during pregnancy. Follow-up at 5-7 years age showed that one of the three children had become seropositive for HBsAg and anti-HBc. This child and one of the other two had detectable HBV DNA at the follow-up, with whole genome sequences identical to those in HBV from their mothers. CONCLUSIONS Mothers-to-child transmission of HBV can, despite adequate prophylaxis, lead to OBI which may later develop into overt HBV infection. Whether such infections are of clinical importance needs to be further investigated.

Abstract
We describe the epidemiology of hepatitis B virus (HBV) infection among women of reproductive age residing in areas of China that are highly endemic for chronic HBV, and provide evidence useful for decision-makers to guide strategies for preventing mother-to-child transmission of HBV, and assess the impact of perinatal transmission PMTCT by projecting HBsAg prevalence trends without interventions. We conducted a cross-sectional HBV serological survey of women, 15-49 years of age, residing in Fujian, Guangdong, Guangxi and Hainan provinces. Demographic and other subject-level data were collected in face-to-face interviews, after which we obtain blood specimens. Specimens were tested for HBV sero-markers by ELISA (Beijing Wantai Biological Pharmacy), and HBV DNA was tested with PCR (Hunan Sansure Biotech). Weighted HBsAg and HBV (either HBsAg+ or anti-HBc+ indicating either present or past infection) prevalences were 11.82% and 57.16%, respectively. Among the HBsAg-positive women, 27% were also HBeAg positive. The proportion of individuals with HBV DNA loads >105 IU/mL declined with increasing age. Among HBsAg-negative women, 0.9% had occult HBV infection. The prevalence of chronic HBV infection among reproductive women in these highly endemic provinces is high, posing a threat to maternal health and risk of mother-to-child transmission. Prevention of mother-to-child transmission remains critically important.

Abstract
Hepatitis B virus (HBV) infection causes long-term, life-threatening liver diseases worldwide. HBV is transmitted through either the horizontal or mother-to-infant route, which is the major route of transmission in endemic areas. Administration of hepatitis B immunoglobulin and hepatitis B vaccine to newborns of infected mothers prevents mother-to-infant transmission. Implementation of a universal hepatitis B vaccination program has proven successful in eliminating the infection and related complications. Nevertheless, efforts are still needed to improve global coverage of the hepatitis B vaccine. Infants born to highly viremic mothers are still at risk of infection despite current immunoprophylaxis. An increasing number of reports have shown promising efficacy and safety profiles with the use of nucleoside/nucleotide analogues in highly viremic pregnant women to prevent mother-to-infant transmission.

Abstract
BACKGROUND AND AIM To prospectively evaluate the efficacy of vaccine alone compared with vaccine plus HBIG for preventing HBV transmission in neonates of HBsAg (+)/HBeAg (-) mothers. METHODS Combined immunization is currently recommended for neonates of HBsAg (+) mothers in China. As a result, a randomized design is infeasible due to ethical reasons. In practice, Guangxi Zhuang Autonomous Region and Jiangsu Province implement vaccine alone and vaccine plus HBIG strategies for neonates born to HBsAg (+)/HBeAg (-) mothers, respectively. We alternatively enrolled neonates of HBsAg (+)/HBeAg (-) mothers from these two regions. Three doses of a recombinant yeast-derived hepatitis B vaccine were given at 0, 1 and 6months with or without HBIG at birth. RESULTS At 7months, sera were collected from 132 neonates in Guangxi Zhuang Autonomous Region and 752 neonates in Jiangsu Province. Baseline characteristics of both mothers and neonates were comparable in the two regions. No differences were revealed regarding the occurrence of perinatal HBV transmission with or without HBIG at birth [0.1% (1/752) vs. 0.0% (0/132), p=1.000]. The anti-HBs response rates were 97.7% (129/132) and 98.5% (740/751) for the neonates with vaccine alone and with HBIG (p=0.758), respectively. Vaccine alone induced a significantly higher anti-HBs GMC as compared to vaccine plus HBIG at 7months of age (1555.3mIU/mL vs. 654.9mIU/mL, p<0.0001). At 12months of age, protective levels of anti-HBs remained in 97.4% (596/612) and 98.3% (118/120) of the neonates receiving and not receiving HBIG, respectively (p=0.771). The neonates receiving combined prophylaxis had a markedly lower anti-HBs GMC (210.7mIU/mL vs. 297.0mIU/mL, p=0.011). Horizontal HBV transmission occurred in none of the successfully immunized neonates for both compared groups at 12months of age. CONCLUSIONS Vaccine alone may be enough for preventing HBV transmission in neonates of HBsAg (+)/HBeAg (-) mothers.

Abstract
BACKGROUND/AIM The aim of this study was to investigate the factors that influence hepatitis B virus (HBV) expression and replication in the ovum. MATERIALS AND METHODS Immunohistochemistry and in situ hybridization techniques were used to assay the distributions of HBcAg, HBV DNA, and HBV mRNA in ovarian tissues and the ovum in 50 patients with chronic HBV infection. HBeAg and HBV DNA in the serum were also detected. Comparisons of categorical data were performed using McNemar test. RESULTS The positive rates of HBcAg, HBV DNA, and HBV mRNA in ovum and ovarian tissues of high replication group were significantly higher than low replication group (χ2 = 15.04, P< 0.05; χ2 = 12.96, P<0.05; χ2 = 19.36, P< 0.05; respectively). High positive rates of HBcAg, HBV DNA, and HBV mRNA in ovum and ovarian tissues were found in women with HBeAg-positive than HBeAg-negative (χ2 = 113.14,P< 0.05; χ2 = 11.13, P< 0.05; χ2 = 17.39, P< 0.05; respectively). CONCLUSION HBV can infect and replicate in the ovary and ovum. Maternal HBeAg status and HBV DNA levels are important influencing factors.

Abstract
INTRODUCTION In 2006, Singapore adopted the universal hepatitis B immunoglobulin (HBIg) policy. Since then, all infants of hepatitis B surface antigen (HBsAg)-positive mothers receive HBIg, irrespective of maternal hepatitis B e antigen (HBeAg) status. However, the benefits of HBIg for infants of HBeAg-negative mothers are unclear. We compared the vertical transmission rates among children of HBeAg-negative mothers who were given HBIg versus a retrospective cohort who were not given HBIg, to determine its protective effect. METHODS This observational study involved pregnant HBsAg-positive women seen at National University Hospital, Singapore, between June 2009 and December 2013. If the infants of these mothers completed the recommended vaccination schedule, they were recruited into the study, along with their older siblings. Serological testing for the children was performed three months after completion of the last dose of vaccine, and hepatitis B virus (HBV) surface gene sequencing was carried out if HBV DNA was detected. RESULTS A total of 111 infants and 47 siblings were recruited. 2 (1.5%) children were found to have vertical transmission despite receiving HBIg, while no incidences of vertical transmission were found among the historical controls who did not receive HBIg (p = 1.00). CONCLUSION The overall effectiveness of the hepatitis B vaccination programme for children of HBsAg-positive mothers was high, regardless of HBIg administration. The addition of HBIg did not appear to confer additional benefits, in terms of vertical transmission rate, among infants born to HBeAg-negative mothers.

Abstract
Evaluate safety and immunization coverage of a new kind of recombinant Hepatitis B vaccine (HepB) in Ningbo city, China. Two groups were carried out in 2 of 11 randomly selected countries in Ningbo in 2009. All of the infants born from July 1 to December 31, 2009 were enrolled as subjects and received 3 doses of HepB at 0, 1, 6 month. Control group (N = 3452) received current HepB derived from Saccharomyces Cerevisiae Yeast (HepB made by recombinant DNA techniques in Saccharomyces Cerevisiae Yeast, HepB-SCY; 5 μg/0.5 ml per dose) and experimental group (N = 5104) received the new kind of HepB derived from Hansenula polymorpha Yeast (HepB made by recombinant DNA techniques in Hansenula polymorpha Yeast, HepB-HPY; 10 μg/0.5 ml per dose). 3-dose and timely birth dose (TBD) coverage were available and compared between 2 groups. Standard structured questionnaires were applied to record information from parents and hospitals for selecting determinants of coverage. The data were analyzed using stepwise multiple logistic regression models. After each dose, HepB-related adverse events (AEs) and recta-temperature were recorded for 7 days. 3-dose coverage in control group (89.98%) was higher than that in experimental group (χ2 = 575.1173, P < 0.0001). TBD coverage in control and experimental group were 98.41% and 98.53%, respectively. No statistically significant difference in TBD coverage was found between 2 groups (χ2 = 0.0623, P = 0.8029). A total of 9 local AEs were reported, 4 for control group and 5 for experimental group. The percentages of subjects reporting AEs were similar across the 2 vaccination groups. No serious or immediate reactions were found in this study. From logistic models, receiving 10 μg vaccine (odds ratio [OR]:0.38; 95% confidence interval [95%CI]: 0.34-0.44) and mother migrating from other cities (OR: 0.45; 95%CI: 0.42-0.47) were the determinants for non-acceptance of 3 doses of HepB; infants born from low grade hospitals and native mothers contributed to administrate the TBD.

Abstract
Hepatitis B virus (HBV) infection is usually vertically transmitted from the mother to child during birth in Asian countries. Despite immunization, immunoprophylaxis failure is well-documented. The aim of the study was to study immunoprophylaxis failure rate in the cohort of infants delivered by chronic HBV-infected mothers and to determine risk factors for failure. This was an observational study involving chronic hepatitis B infected mothers seen at a tertiary care center in Singapore between June 2009 and December 2013. Infants born to these mothers were recruited after they had completed the recommended vaccination schedule. Serological testing for the children was performed 3 months after completion of the last dose of vaccine. HBV surface gene sequencing was carried out if HBV DNA was detectable in the children. Among the 161 mothers enrolled, most were HBeAg negative. HBeAg positive mothers were younger and had a significantly higher viral load (6.5 log) as compared to HBeAg negative mothers (1.35 log) (P < 0.001). Four children (2.6%) were found to have immunoprophylaxis failure. Two occurred in children delivered by mothers with extremely high viral load of more than 5 × 10(7) IU/ml. HBV surface gene mutations were detected in most children (3 out of 4) with immunoprophylaxis failure. The overall effectiveness of the hepatitis B vaccination program was high. High maternal viral load and presence of surface gene mutants may be potential contributors.

Abstract
Hepatitis B virus (HBV) causes life-threatening liver disease. It is transmitted through a horizontal route or a mother-to-infant route, and the latter is the major route in endemic areas. Prevention of HBV infection by immunization is the best way to eliminate HBV-related diseases. The HBV vaccine is the first human vaccine using a viral antigen from infected persons, which is safe and effective. Either passive immunization by hepatitis B immunoglobulin (HBIG) or active immunization by HBV vaccine is effective, and a combination of both yields the best efficacy in preventing HBV infection. The impact of universal HBV immunization is huge, with 90%-95% effectiveness in preventing chronic HBV infection. It is the first cancer preventive vaccine with a protective efficacy against hepatocellular carcinoma (HCC) of ∼ 70%. Nevertheless, further effort is still needed to avoid vaccine failure and to increase the global coverage rate.

Abstract
Post-exposure prophylaxis with hepatitis B vaccine (HepB) alone is highly effective in preventing perinatal hepatitis B virus (HBV) transmission and the World Health Organization recommends administering HepB to all infants within 24 h after delivery. Maternal screening for HBsAg and administration of hepatitis B immune globulin (HBIG) in addition to HepB for infants born to HBsAg-positive pregnant women can increase the effectiveness of post-exposure prophylaxis for perinatal HBV transmission. In Shangdong Province, China which has a high prevalence of chronic HBV infection, HepB birth dose and HBIG were integrated into the routine childhood immunization program in 2002 and July 2011 respectively. We assessed progress toward implementation of these measures. Hospital-based reporting demonstrated an increase in maternal screening from 70.7% to 96.9% from 2004-2012; HepB birth dose coverage (within 24 h) remained high (96.3-97.1%) during this period. For infants with known HBsAg-positive mothers, the coverage of HBIG increased from 85.0% (before July 2011) to 92.1% (after July 2011). However, HBIG coverage in western areas of Shandong Province remained at 81.1% among infants with known HBsAg-positive mothers. Preterm/low-birth-weight and illness after birth were the most commonly reported reasons for delay in the first dose of HepB to >24 h of birth. Additional education on the safety and immune protection from HepB and HBIG might help to correct delays in administering the HepB birth dose and low HBIG coverage in the western areas of the Shandong Province.

Abstract
OBJECTIVES The cost-effectiveness of augmenting immunization against hepatitis B infection with hepatitis B immunoglobulin (HBIG) remains controversial, particularly for the subpopulation of babies of HBsAg+/HBeAg- mothers that are considered as low-infective. We aimed to evaluate the effectiveness of vaccine alone compared with vaccine plus HBIG for the immunization of babies of HBsAg+/HBeAg- mothers. METHODS We searched PubMed, Scopus and Cochrane Central Register of Controlled Trials databases to identify studies comparing the effectiveness of combined immunization (vaccine plus HBIG) with vaccine alone in neonates of HBsAg+/HBeAg- mothers. A systematic review and meta-analysis of eligible studies was performed. RESULTS A total of nine eligible studies were identified (four randomized controlled trials). No difference was found regarding the primary outcome of our meta-analysis, namely occurrence of hepatitis B infection, between neonates who received vaccine only, compared with those who received both vaccine and HBIG (four studies, 3426 patients, OR=0.82, 95% CI=0.41-1.64). This finding was consistent with regards to seroprotection rate (four studies, 1323 patients, OR=1.24, 95% CI=0.97-1.58). Safety data were not reported in the included studies. CONCLUSIONS The available limited published evidence suggests that vaccine alone seems to be equally effective to the combination of HBIG and hepatitis B vaccine for neonates of HBsAg+/HBeAg- mothers in preventing infection. Further studies are needed in order to clarify the potential benefit of combined immunization to this specific subgroup of patients.

Effects of hepatitis B immunization on prevention of mother-to-infant transmission of hepatitis B virus and on the immune response of infants towards hepatitis B vaccine. Vaccine 2014; 32:6091-7. [PMID: 25240752 DOI: 10.1016/j.vaccine.2014.08.078] [Citation(s) in RCA: 44] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2014] [Revised: 08/11/2014] [Accepted: 08/30/2014] [Indexed: 12/11/2022]
Abstract
BACKGROUND Combined immunization with hepatitis B immunoglobulin (HBIG) plus hepatitis B vaccine (HB vaccine) can effectively prevent perinatal transmission of hepatitis B virus (HBV). With the universal administration of HB vaccine, anti-HBs conferred by HB vaccine can be found increasingly in pregnant women, and maternal anti-HBs can be passed through the placenta. This study was designed to evaluate the effect of hepatitis B immunization on preventing mother-to-infant transmission of HBV and on the immune response of infants towards HB vaccine. METHOD From 2008 to 2013, a prospective study was conducted in 15 centers in China. HBsAg-positive pregnant women and their infants aged 8-12 months who completed immunoprophylaxis were enrolled in the study and tested for HBV markers (HBsAg, anti-HBs, HBeAg, anti-HBe and anti-HBc). Antepartum administration of HBIG to HBsAg-positive women was based on individual preference. HBsAg-negative pregnant women and their infants of 7-24 months old who received HB vaccines series were enrolled and tests of their HBV markers were performed. RESULTS 1202 HBsAg-positive mothers and their infants aged 8-12 months were studied and 40 infants were found to be HBsAg positive with the immunoprophylaxis failure rate of 3.3%. Infants with immunoprophylaxis failure were all born to HBeAg-positive mothers of HBV-DNA ≥6 log₁₀copies/ml. Among infants of HBeAg-positive mothers, immunoprophylaxis failure rate in vaccine plus HBIG group, 7.9% (29/367), was significantly lower than the vaccine-only group, 16.9% (11/65), p=0.021; there was no significant difference in the immunoprophylaxis failure rate whether or not antepartum HBIG was given to the pregnant woman, 10.3% (10/97) vs 9.0% (30/335), p=0.685. Anti-HBs positive rate was 56.3% (3883/6899) among HBsAg-negative pregnant women and anti-HBs positive rate was 94.2% in cord blood of anti-HBs-positive mothers. After completing the HB vaccine series, anti-HBs positive rate among infants with maternal anti-HBs titers of <10 IU/L, 10-500 IU/L and ≥500 IU/L was 90.3% (168/186), 90.5% (219/242) and 80.2% (89/111) respectively, p=0.011. Median titers of anti-HBs (IU/L) among infants in the three groups was 344.2, 231.9 and 161.1 respectively, p=0.020. CONCLUSIONS HBIG plus HB vaccine can effectively prevent mother-to-infant transmission of HBV, but no HBV breakthrough infection was observed in infants born to HBeAg-negative mothers who received HB vaccine with or without HBIG after birth. Antepartum injection of HBIG has no effect on preventing HBV mother-to-infant transmission. High maternal titer of anti-HBs can transplacentally impair immune response of infants towards HB vaccine.

Abstract
UNLABELLED Hepatitis B virus (HBV) infection is of high prevalence in China. Mother-to-infant transmission is the major route for HBV transmission and subsequent chronicity. This study aimed to investigate current HBsAg-positive rate among pregnant women and immunoprophylaxis outcome in China. Multicenter prospective study was conducted in 10 centers. From 2008 to 2012, 67,720 pregnant women were screened and 1,150 HBsAg-carrier mothers and their infants aged 8-12 months were studied in four out of all centers, among whom HBV markers (HBsAg, HBsAb, HBeAg, HBeAb, and HBcAb) and HBV DNA (in three centers) were measured. The results showed that HBsAg-positive rate of pregnant women was 6.7 % (4,533/67,720) and infants' immunoprophylaxis failure rate was 3.4 % (39/1,150). Immunoprophylaxis failure infants were all born to mothers of HBeAg-positive and HBV DNA ≥6 log10 copies/ml. Among infants of HBeAg-positive mothers, multivariable analyses showed the following: mother's age <28 years vs ≥28 years, RR = 0.157, 95 % confidence interval (CI) [0.067, 0.369], p = 0.000; Neonates receiving vaccine vs vaccine plus hepatitis B immune globulin (HBIG), RR = 0.371, 95 % CI [0.167, 0.825], p = 0.015. Pregnant women receiving HBIG in the third trimester, vaginal delivery and breastfeeding had no significant effects on HBV mother-to-infant transmission. CONCLUSIONS Pregnant women are still of high HBsAg prevalence in China. HBV mother-to-infant transmission still occurs after passive-active immunization. Pregnant women of high HBV replication levels are the major risk population of HBV mother-to-infant transmission. Passive-active immunization is necessary for neonates of HBeAg-positive mothers. Mother's age <28 years and neonate receiving vaccine only were the risk factors for HBV mother-to-infant transmission. Breastfeeding did not put children at risk of mother-to-infant transmission.

Abstract
BACKGROUND Despite effective immunoprophylaxis, vertical transmission of hepatitis B virus (HBV) from infected mothers still occurs. This study aimed to provide an estimate of the prevalence of immunoprophylaxis failure and evaluate associated risk factors. METHODS A hospital-based prospective study was conducted from June 1, 2008, to June 30, 2012. In this prospective study, 294 HBsAg-positive mothers were followed up from their first prenatal care visits until their infants completed the proposed vaccination schedule. Further, studies providing prevalence rates of immunoprophylaxis failure in the Chinese population were identified from electronic databases and were collected for a meta-analysis. RESULTS In the prospective study, 16 (5.44%) infants developed HBV infection despite passive-active immunoprophylaxis. Twelve of these infants were born to HBeAg-positive mothers with cord blood that was positive for HBV DNA. After adjusting for maternal and infant factors, HBV DNA detectable in cord blood (odds ratio: 22.32, 95% confidence interval: 4.00-124.47) was associated with a significantly greater risk of immunoprophylaxis failure. The prospective study and 23 previous studies were included in the meta-analysis, constituting a total of 7561 Chinese participants. The overall estimated rates of immunoprophylaxis failure for infants with HBsAg-positive and HBeAg-positive mothers were 4.87% and 9.66% respectively. CONCLUSIONS Immunoprophylaxis failure is an extensive problem, and further studies should design and assess novel strategies for the prevention of immunoprophylaxis failure, especially for cases involving HBeAg-positive mothers and infants with cord blood that is positive for HBV DNA.

Hepatitis B vaccine response among infants born to hepatitis B surface antigen-positive women. Vaccine 2014; 32:2127-33. [PMID: 24560676 DOI: 10.1016/j.vaccine.2014.01.099] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2013] [Revised: 01/14/2014] [Accepted: 01/30/2014] [Indexed: 12/16/2022]
Abstract
PURPOSE Annually, an estimated 25,000 infants are born to hepatitis B surface antigen (HBsAg)-positive women in the United States. Hepatitis B (HepB) vaccine and hepatitis B immune globulin (HBIG) are recommended at birth, followed by completion of vaccine series and post-vaccination serologic testing (PVST). In a large cohort of infants born to HBsAg-positive women, factors influencing vaccine response were evaluated. METHODS Data were from HBsAg-negative infants born to HBsAg-positive women in the Enhanced Perinatal Hepatitis B Prevention Program (EPHBPP) from 2008 to 2013. Vaccine non-responders were defined as infants with antibody to hepatitis B surface antigen (anti-HBs) <10mIU/mL at PVST after receiving ≥3 vaccine doses. Multivariable analyses modeled statistically significant predictor variables associated with non-response. RESULTS A total of 17,951 maternal-infant pairs were enrolled; 8654 HBsAg-negative infants born to HBsAg-positive mothers received ≥3 doses of vaccine with anti-HBs results. 8199 (94.7%) infants responded to a primary HepB series; 199 (94.8%) to a second series. Factors associated with anti-HBs <10mIU/mL included gestational age <37 weeks, vaccine birth dose >12h after birth, timing of final vaccine dose <6 months after birth, receipt of 3 vs. 4 vaccine doses, and PVST interval >6 months from final vaccine dose in bivariate analysis. PVST interval >6 months from final vaccine dose (OR=2.7, CI=2.0, 3.6) was significantly associated with anti-HBs <10mIU/mL; the proportion increased from 2% at 1-2 months to 21.6% at 15-16 months after the final dose. Receipt of a 4th dose improved the response rate (OR=0.5, CI=0.3, 0.8). CONCLUSIONS Ninety-five percent of a large cohort of uninfected infants born to HBsAg-positive mothers in the United States responded to primary HepB vaccine series. The proportion of infants with anti-HBs <10mIU/mL increased with longer interval between the final vaccine dose and PVST. Optimal timing of PVST is within 1-2 months of final vaccine dose to avoid unnecessary revaccination.

Schillie SF, Murphy TV. Seroprotection after recombinant hepatitis B vaccination among newborn infants: a review. Vaccine 2012; 31:2506-16. [PMID: 23257713 DOI: 10.1016/j.vaccine.2012.12.012] [Citation(s) in RCA: 66] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2012] [Revised: 07/09/2012] [Accepted: 12/03/2012] [Indexed: 12/18/2022]
Abstract
INTRODUCTION Hepatitis B vaccination starting at birth provides a safety net for infants exposed to hepatitis B virus (HBV) during delivery or in early life. Hepatitis B vaccine is recommended in the United States for infants prior to birthing facility discharge, and within the first 12h of life for infants born to hepatitis B surface antigen (HBsAg)-positive mothers. We performed a literature review and summarized the response to recombinant hepatitis B vaccine among infants. METHODS Studies published between 1987 and 2011 assessing seroprotection from recombinant hepatitis B vaccine starting within the first 30 days of life were eligible. Seroprotection was defined using an antibody to hepatitis B surface antigen (anti-HBs) threshold of 10mIU/mL at series completion. Infant seroprotection was compared in trial arms varying by maternal hepatitis B antigen status (e antigen [HBeAg], HBsAg), hepatitis B immune globulin (HBIG) administration, birth weight, vaccine dosage, schedule, and age at first dose. RESULTS Forty-three studies were included. The median seroprotection proportion overall was 98% (range 52%, 100%). The final median seroprotection proportions did not vary appreciably by maternal HBsAg status, HBIG administration, or schedule. Higher compared to lower dosage resulted in earlier increases in anti-HBs but not in final seroprotection proportions. Infants with birth weights <2000g compared to ≥2000g had lower median seroprotection proportions (93% and 98%, respectively). Median seroprotection proportions were also lower when infants with birth weights <2000g were vaccinated at 0-3 days of age compared to 1 month of age or older (68% versus 95%, respectively). CONCLUSION High levels of protection from recombinant hepatitis B vaccine are achieved in term infants vaccinated at birth, effectively preventing transmission of HBV and resultant morbidity and mortality. Implications, if any, for long-term protection are unknown for differences in responses among infants vaccinated at birth compared to ages older than 1 month.

Abstract
The management of chronic hepatitis B virus (HBV) infection requires understanding the natural history of the disease as well as the risks, benefits, and limitations of the therapeutic options. This article covers the principles governing when to start antiviral therapy, discusses recent advances using hepatitis B surface antigen quantification to better define various phases of infection, describes the use of HBV core, precore, and viral genotyping as well as host IL28B genotyping to predict response to interferon therapy, and reports on the management of HBV in 3 special populations (pregnancy, postliver transplantation, and in the setting of chemotherapy or immunosuppression).

Effects of maternal screening and universal immunization to prevent mother-to-infant transmission of HBV. Gastroenterology 2012; 142:773-781.e2. [PMID: 22198276 DOI: 10.1053/j.gastro.2011.12.035] [Citation(s) in RCA: 179] [Impact Index Per Article: 14.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2011] [Revised: 12/06/2011] [Accepted: 12/09/2011] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Mother-to-infant transmission is the major cause of hepatitis B virus (HBV) infection among immunized children. There has been much debate about screening pregnant women and administering hepatitis B immunoglobulin (HBIG) to newborns. We analyzed the rate of HBV infection among children born to hepatitis B surface antigen (HBsAg)-positive mothers and whether HBIG administration reduces transmission. METHODS We analyzed data from 2356 children born to HBsAg-positive mothers, identified through prenatal maternal screens. In addition to HBV vaccines, HBIG was given to all 583 children with hepatitis B e antigen (HBeAg)-positive mothers and to 723 of 1773 children with HBeAg-negative mothers. Serology tests for HBV were performed from 2007 to 2009, when children were 0.5-10 years old. RESULTS A significantly greater percentage of children with HBeAg-positive mothers tested positive for antibodies against the hepatitis B core protein (16.76%) and HBsAg (9.26%) than children with HBeAg-negative mothers (1.58% and 0.29%, respectively; P < .0001 and <.001). Among the HBV-infected children, the rate of chronicity also was higher among children with HBeAg-positive mothers than children with HBeAg-negative mothers (54% vs 17%; P = .002). Similar rates of antibodies against the hepatitis B core protein (0.99% and 1.88%; P = .19) and HBsAg (0.14% and 0.29%; P = .65) were noted in children born to HBeAg-negative mothers who were or were not given HBIG. Infantile fulminant hepatitis developed in 1 of 1050 children who did not receive HBIG (.095%). CONCLUSIONS Children born to HBeAg-positive mothers are at greatest risk for chronic HBV infection (9.26%), despite immunization. Administration of HBIG to infants born to HBeAg-negative mothers did not appear to reduce the rate of chronic HBV infection, but might prevent infantile fulminant hepatitis. Screening pregnant women for HBsAg and HBeAg might control mother-to-infant transmission of HBV.

Abstract
In infants born to hepatitis B surface antigen (HBsAg)-positive mothers, failure after passive-active immunization still occurs. The role of maternal hepatitis B DNA level and other risk factors in this setting remains unclear. This study retrospectively evaluated virologic and other risk factors associated with immunoprophylaxis failure in infants born to HBsAg-positive mothers. Between January 2007 and March 2010, we reviewed the clinical and virologic tests in 869 mother-infant pairs. All infants received the identical passive-active immunization schedule after birth. The failure infants (HBsAg positive at 7-12 months of age) were compared to infants who were HBsAg negative when tested during this time period. Among 869 infants, 27 (3.1%) infants were immunoprophylaxis failures and the other 842 (96.9%) infants remained HBsAg negative. When mothers' pre-delivery HBV DNA levels were stratified to <6, 6-6.99, 7-7.99 and ≥ 8 log(10) copies/mL, the corresponding rates of immunoprophylaxis failure were 0%, 3.2% (3/95), 6.7% (19/282) and 7.6% (5/66), respectively (P < 0.001 for the trend). All failure infants were born to hepatitis B e antigen (HBeAg)-positive mothers. Multivariate logistic regression analysis identified maternal HBV DNA levels [odds ratio (OR) = 1.88, 95% confidence interval (CI): 1.07-3.30] and detectable HBV DNA in the cord blood (OR = 39.67, 95% CI: 14.22-110.64) as independent risk factors for immunoprophylaxis failure. All failure infants were born to HBeAg-positive mothers with HBV DNA levels ≥ 6 log(10) copies/mL. The presence of HBV DNA in cord blood predicted failure to passive-active immunization.

Abstract
OBJECTIVE To evaluate the compliance with the protocol for preventing perinatal hepatitis B infection in Italy, including HBsAg screening of pregnant women and immunization of newborns to infected mothers. METHODS Women consecutively delivering, over 6 months in 2008-2009, in public and private hospitals of 13 Italian regions were recruited. Data on socio-demographic characteristics, HBsAg prenatal screening and newborns immunization were collected. RESULTS 17,260 pregnant women were enrolled. Of them 16,858 (97.7%) attended prenatal screening. Delivering in a public hospital and in hospitals located in South Italy were both independent predictors of non-adherence to HBsAg screening. Foreign pregnant women were also less likely to be screened. Overall, HBsAg prevalence was 0.86%; it was 0.4% for Italian women and 2.5% for foreign women. Differences in prevalence by country of origin and education were statistically significant. Of 138 newborns from HBsAg positive mothers 131 received passive/active immunization; 7 newborns received just vaccine. CONCLUSION In this study compliance with the protocol for preventing perinatal hepatitis B was very good. Further efforts are needed to improve adherence to prenatal screening in public hospitals, in hospital located in southern Italy and among foreign women. HBV spread in Italy is progressively declining, also involving immigrant population.

Abstract
This article will focus on the impact caused by chronic viral hepatitis B and C globally and will discuss public health measures that have to be implemented in order to prevent and control these diseases. Chronic viral hepatitis is a major global public health problem, an important cause of morbidity and mortality from sequelae which include chronic hepatitis, cirrhosis and primary liver cancer. Being a 'silent' disease, the contribution of chronic hepatitis to global morbidity and mortality is generally underestimated. Hepatitis B and C prevention and control should seek to reduce both the incidence of new infections and the risk of chronic liver disease. A comprehensive public health prevention programme should include the prevention and detection of HBV and HCV infections, the diagnosis and control of viral hepatitis related chronic liver disease, conducting surveillance and monitoring the effectiveness of prevention activities, and setting up a research agenda.

Abstract
BACKGROUND/AIMS In this revaccination study, we explored the determinants of response to booster hepatitis B (HB) vaccination in anti-HBs-seronegative adolescents who had received primary HB vaccination 15-18 years before. RESULTS After controlling for prebooster anti-HBs levels, cigarette smoking, betel-quid chewing, alcohol drinking, and indigenous ethnicity were significantly associated with elevated risks of non-response to booster HB vaccination. The adjusted odds ratios (aORs) were 3.21 (CI: 1.33-7.84), 8.78 (CI: 2.03-37.94), 2.64 (CI: 1.15-6.02), and 2.46 (CI: 1.28-4.72), respectively. Among adolescents with undetectable prebooster anti-HBs titers, only indigenous ethnicity significantly associated with elevated risk, with an adjusted OR of 2.57 (CI: 1.20-5.54), of non-response to booster HB vaccination. On the contrary, the influences of cigarette smoking, betel-quid chewing, and alcohol drinking were restricted to adolescents with prebooster anti-HBs titers of 0.1-9.9mIU/mL. The corresponding multivariate-adjusted ORs were 5.70, 17.41, and 3.72, respectively. Adolescents who smoked cigarettes and chewed betel-quid were at highest risk of non-response (aOR, 25.3; CI: 2.97-215.7). CONCLUSIONS A booster dose of HB vaccine may be insufficient to induce immunological response in healthy adolescents who had undetectable prebooster anti-HBs titers or who were of Malay-Polynesian ethnicity. Responses to booster vaccination are probably modified by recent cigarette smoking and/or betel-quid chewing.

Abstract
OBJECTIVE Seroprevalence of HBsAg in 26,746 women at reproductive age in Greece and evaluation of HBeAg/anti-HBe serological status as well as serum HBV-DNA levels in a subgroup of HBsAg(+) women at labor. STUDY DESIGN Serological markers were detected using enzyme immunoassays. Serum HBV-DNA was calculated using a sensitive quantitative PCR assay, with a lower limit of quantification of 200 copies/ml. RESULTS Overall, 1.53% of women were HBsAg(+) and the majority of them (64.96%) were Albanian. Among Albanian women the mean prevalence of HBsAg was 4.9%, 5.57% among Asian women, and 1.29% among women from Eastern European countries. The prevalence of HBsAg among African (0.29%) and Greek women (0.57%) was very low and significantly lower in comparison with the mean value of the studied population. Only 2.67% of HBsAg(+) women were HBeAg(+). Of a subgroup of women in labor with available serum samples 28.6% had undetectable levels of viremia (<200 copies/ml) and 15.9% had extremely low levels of viral replication (<400 copies/ml). Only 12.7% of pregnant women evaluated at labor exhibited extremely high serum HBV-DNA levels (>10,000,000 copies/ml) whereas 42.8% of them exhibited HBV-DNA levels between 1500 and 40,000 copies/ml. CONCLUSIONS The overall prevalence of HBsAg is relatively low among women at reproductive age in Greece but is higher among specific ethnic populations (Asian, Albanian). The HBeAg(-)/antiHBe(+) serological status is a finding observed in the vast majority of HBsAg(+) women of our study population, and a significant percentage of them (approximately 44.5%) exhibit extremely low or even undetectable levels of viral replication at labor, suggesting possibly that only a proportion of HBsAg(+) women in Greece exhibit an extremely high risk of vertical transmission of the infection.

Abstract
BACKGROUND Hepatitis B vaccine and hepatitis B immunoglobulin are considered for newborn infants of HBsAg-positive mothers to prevent hepatitis B infection. OBJECTIVES To assess the beneficial and harmful effects of hepatitis B vaccines and hepatitis B immunoglobulin in newborn infants of HBsAg-positive mothers. SEARCH STRATEGY Trials were identified through The Cochrane Neonatal Group Controlled Trials Register, The Cochrane Hepato-Biliary Group Controlled Trials Register, The Cochrane Central Register of Controlled Trials in The Cochrane Library, MEDLINE, and EMBASE (until February 2004), authors of trials, and pharmaceutical companies. SELECTION CRITERIA Randomised clinical trials comparing: plasma-derived vaccine (PDV) or recombinant vaccine (RV) versus no intervention, placebo, or other active vaccines; hepatitis B immunoglobulin versus no intervention, placebo, or other control immunoglobulin; as well as PDV or RV plus hepatitis B immunoglobulin versus no intervention, placebo, or other control vaccines or immunoglobulin. DATA COLLECTION AND ANALYSIS Outcomes are assessed at maximal follow-up. The primary outcome measure was hepatitis B occurrence, based on a blood specimen positive for HBsAg, HBeAg, or antibody to hepatitis B core antigen (anti-HBc). Binary outcomes are reported as relative risks (RR) with 95% confidence interval (CI). Subgroup analyses were performed with regard to methodological quality of the trial, mother's HBe-Ag status, and time of immunisation after birth. MAIN RESULTS We identified 29 randomised clinical trials, five of which were considered high quality. Only three trials reported inclusion of hepatitis B e-antigen negative mothers. Compared with placebo/no intervention, vaccine reduced hepatitis B occurrence (RR 0.28, 95% confidence interval (CI) 0.20 to 0.40, 4 trials). No significant differences of hepatitis B occurrence were found comparing recombinant vaccine (RV) versus plasma-derived vaccine (PDV) (RR 1.00, 95% CI 0.71 to 1.42, 4 trials) and high-dose versus low-dose vaccine (PDV: RR 0.97, 95% CI 0.55 to 1.68, 3 trials; RV: RR 0.78, 95% CI 0.31 to 1.94, 1 trial). Compared with placebo/no intervention, hepatitis B immunoglobulin or the combination of vaccine plus hepatitis B immunoglobulin reduced hepatitis B occurrence (hepatitis B immunoglobulin: RR 0.50, 95% CI 0.41 to 0.60, 1 trial; PDV plus hepatitis B immunoglobulin: RR 0.08, 95% CI 0.03 to 0.17, 3 trials). Compared with vaccine, vaccine plus hepatitis B immunoglobulin reduced hepatitis B occurrence (RR 0.54, 95% CI 0.41 to 0.73, 10 trials). Hepatitis B vaccine and hepatitis B immunoglobulin seem safe, but few trials reported on adverse events. AUTHORS' CONCLUSIONS Vaccine, hepatitis B immunoglobulin, and vaccine plus hepatitis B immunoglobulin prevent hepatitis B occurrence in newborn infants of HBsAg positive mothers.

Abstract
OBJECTIVE To evaluate the effects of hepatitis B vaccine and immunoglobulin in newborn infants of mothers positive for hepatitis B surface antigen. DESIGN Systematic review and meta-analysis of randomised clinical trials. DATA SOURCES Electronic databases and hand searches. REVIEW METHODS Randomised clinical trials were assessed for methodological quality. Meta-analysis was undertaken on three outcomes: the relative risks of hepatitis B occurrence, antibody levels to hepatitis B surface antigen, and adverse events. RESULTS 29 randomised clinical trials were identified, five of which were considered high quality. Only three trials reported inclusion of mothers negative for hepatitis B e antigen. Compared with placebo or no intervention, vaccination reduced the occurrence of hepatitis B (relative risk 0.28, 95% confidence interval 0.20 to 0.40; four trials). No significant difference in hepatitis B occurrence was found between recombinant vaccine and plasma derived vaccine (1.00, 0.71 to 1.42; four trials) and between high dose versus low dose vaccine (plasma derived vaccine 0.97, 0.55 to 1.68, three trials; recombinant vaccine 0.78, 0.31 to 1.94, one trial). Compared with placebo or no intervention, hepatitis B immunoglobulin or the combination of plasma derived vaccine and hepatitis B immunoglobulin reduced hepatitis B occurrence (immunoglobulin 0.50, 0.41 to 0.60, one trial; vaccine and immunoglobulin 0.08, 0.03 to 0.17, three trials). Compared with vaccine alone, vaccine plus hepatitis B immunoglobulin reduced hepatitis B occurrence (0.54, 0.41 to 0.73; 10 trials). Hepatitis B vaccine and hepatitis B immunoglobulin seem safe, but few trials reported adverse events. CONCLUSION Hepatitis B vaccine, hepatitis B immunoglobulin, and vaccine plus immunoglobulin prevent hepatitis B occurrence in newborn infants of mothers positive for hepatitis B surface antigen.

HBeAg negative serological status and low viral replication levels characterize chronic hepatitis B virus-infected women at reproductive age in Greece: A one-year prospective single center study.

Abstract
AIM: To evaluate the seroprevalence of hepatitis B surface antigen (HBsAg) in 13 581 women at reproductive age and the hepatitis B e antigen (HBeAg)/anti-HBe status as well as serum hepatitis B virus (HBV)-DNA levels in a subgroup of HBsAg(+) pregnant women at labor in Greece.
METHODS: Serological markers were detected using enzyme immunoassays. Serum HBV-DNA was determined by a sensitive quantitative PCR assay. Statistical analysis of data was based on parametric methodology.
RESULTS: Overall, 1.156% of women were HBsAg(+) and the majority of them (71.3%) were Albanian. The prevalence of HBsAg was 5.1% in Albanian women, 4.2% in Asian women and 1.14% in women from Eastern European countries. The prevalence of HBsAg in African (0.36%) and Greek women (0.29%) was very low. Only 4.45% of HBsAg(+) women were also HBeAg(+) whereas the vast majority of them were HBeAg(-)/anti-HBe(+). Undetectable levels of viremia (<200 copies/mL) were observed in 32.26% of pregnant women at labor and 29.03% exhibited extremely low levels of viral replication (<400 copies/mL). Only two pregnant women exhibited extremely high serum HBV-DNA levels (>10 000 000 copies/mL), whereas 32.26% exhibited HBV-DNA levels between 1 500 and 40 000 copies/mL.
CONCLUSION: The overall prevalence of HBsAg is relatively low among women at reproductive age in Greece but is higher enough among specific populations. The HBeAg(-)/anti-HBe(+) serological status and the extremely low or even undetectable viral replicative status in the majority of HBsAg(+) women of our study population, suggest that only a small proportion of HBsAg(+) women in Greece exhibit a high risk for vertical transmission of the infection.
