Abstract
Background Mother-to-child transmission (MTCT) is the most common propagation mode of hepatitis B virus (HBV) transmission. Exploring the mechanisms of HBV MTCT is the key to protect infant from infection. In this study, we aim to clarify the important role of autophagy complicated in HBV MTCT. Methods A total of 169 placental samples were collected in this study, includes 144 HBV positive pregnant women and 25 normal pregnant women. In vitro, JEG-3 cells were treated with serum contained different HBV viral loads. Electron microscope was used to observed the number of autophagosome. RT-qPCR and western blotting were used to measure the expression level of autophagy relative genes and proteins respectively. Immunofluorescence was used to analyzed the expression of LC-3 of the frozen section of placental tissue. Results According to the number of autophagosomes and the expression level of autophagic genes mRNA and protein, autophagy was increased in HBV maternal placenta. Among the control, low viral load, medium viral load and high viral load groups, autophagy was significantly up-regulated with the increase of HBV viral loads. Also, autophagy was increased in the HBeAg positive pregnant women compared with their HBeAg negative counterparts. Also, autophagy in infant-infected group was up-regulated compared with infant-uninfected group. In vitro, choriocarcinoma JEG-3 cells were treated with the different HBV viral loads or different time incubation, the mRNA and protein of autophagy related genes was maximum expression in the medium viral load or treatment in a short period, but decreased in the high viral load treatment or with long-term HBV exposure. Conclusion Our study determines the high levels of viremia could be the cause of both increase autophagy activities and MTCT. Autophagy was significantly up-regulated in pregnant women with high viral load or HBeAg positive, which plays an important part in the HBV MTCT.

Efficacy and safety of antiviral prophylaxis during pregnancy to prevent mother-to-child transmission of hepatitis B virus: a systematic review and meta-analysis. THE LANCET. INFECTIOUS DISEASES 2020; 21:70-84. [PMID: 32805200 DOI: 10.1016/s1473-3099(20)30586-7] [Citation(s) in RCA: 58] [Impact Index Per Article: 14.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/11/2020] [Revised: 06/10/2020] [Accepted: 07/10/2020] [Indexed: 12/20/2022]
Abstract
BACKGROUND To eliminate mother-to-child transmission (MTCT) of hepatitis B virus (HBV), peripartum antiviral prophylaxis might be required for pregnant women infected with HBV who have a high risk of MTCT despite infant immunoprophylaxis. We aimed to determine the efficacy and safety of peripartum antiviral prophylaxis to inform the 2020 WHO guidelines. METHODS In this systematic review and meta-analysis, we searched PubMed, Embase, Scopus, CENTRAL, CNKI, and Wanfang for randomised controlled trials and non-randomised studies of peripartum antiviral prophylaxis versus placebo or no prophylaxis, with no language restriction, published from database inception until March 28, 2019. We used search terms covering HBV, antiviral therapy, and pregnancy. We included studies that enrolled pregnant women with chronic infection with HBV who received antiviral prophylaxis anytime during pregnancy; that included any of the following antivirals: adefovir, emtricitabine, entecavir, lamivudine, telbivudine, tenofovir alafenamide fumarate, and tenofovir disoproxil fumarate; and that reported the following outcomes: MTCT, indicated by infant HBsAg positivity or HBV DNA positivity, or both, at age 6-12 months, and any infant or maternal adverse events. Two reviewers independently extracted data. Our primary endpoint was MTCT based on infant HBsAg positivity. We assessed pooled odds ratios (ORs) of the efficacy of peripartum antiviral prophylaxis to reduce the risk of MTCT. We assessed safety of prophylaxis by pooling risk differences. The protocol for the systematic review was pre-registered in PROSPERO, CRD42019134614. FINDINGS Of 7463 articles identified, 595 articles were eligible for full-text review and 129 studies (in 157 articles) were included. The following antivirals were assessed in the meta-analysis: tenofovir disoproxil fumarate 300 mg (19 studies, with 1092 mothers and 1072 infants), lamivudine 100-150 mg (40 studies, with 2080 mothers and 2007 infants), and telbivudine 600 mg (83 studies, with 6036 mothers and 5971 infants). The pooled ORs for randomised controlled trials were similar, at 0·10 (95% CI 0·03-0·35) for tenofovir disoproxil fumarate, 0·16 (0·10-0·26) for lamivudine, and 0·14 (0·09-0·21) for telbivudine. The pooled ORs in non-randomised studies were 0·17 (0·10-0·29) for tenofovir disoproxil fumarate, 0·17 (0·12-0·24) for lamivudine, and 0·09 (0·06-0·12) for telbivudine. We found no increased risk of any infant or maternal safety outcomes after peripartum antiviral prophylaxis. INTERPRETATION Peripartum antiviral prophylaxis is highly effective at reducing the risk of HBV MTCT. Our findings support the 2020 WHO recommendation of administering antivirals during pregnancy, specifically tenofovir disoproxil fumarate, for the prevention of HBV MTCT.

Efficacy and safety of telbivudine and tenofovir disoproxil fumarate in preventing hepatitis B vertical transmission: A real-life practice. J Viral Hepat 2019; 26:1170-1177. [PMID: 31177596 DOI: 10.1111/jvh.13156] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/11/2019] [Revised: 04/17/2019] [Accepted: 05/08/2019] [Indexed: 12/12/2022]
Abstract
Mother-to-child transmission (MTCT) is a major obstacle in the elimination of hepatitis B virus (HBV) infection. Telbivudine (LdT) and tenofovir disoproxil fumarate (TDF) are the two most common antiviral medicines for preventing MTCT. However, the efficacy and safety of LdT and TDF in preventing HBV vertical transmission during the second to third trimester have not been compared rigorously. Therefore, we carried out a prospective multicentre cohort study of chronic hepatitis B in mothers with HBV DNA > 106 IU/mL, receiving LdT or TDF during the second to third trimester. Among the 893 mothers enrolled, 857 (LdT/TDF/untreated group (NTx) = 396/325/136) completed consecutive follow-up with 854 infants (LdT/TDF/NTx = 395/323/136). LdT and TDF treatment resulted in a similar decrease of HBV DNA in mothers at delivery. Multivariate analysis indicated that only HBsAg titre at the baseline correlated with viral DNA decrease (P = 0.015). With intention-to-treat analysis, MTCT rates in the LdT, TDF and NTx group were 4.41%, 2.42% and 22.08%, respectively. An increasing vertical transmission rate was found to be closely associated with higher HBsAg titre, 5.32% and 17.65% infection rate was estimated in infants born to mothers with HBsAg > 4 and >5 log10 IU/mL, respectively. No serious side effects were reported in either mothers or infants. LdT and TDF treatments were well tolerated and showed comparable efficacy in reducing MTCT. Higher risk of MTCT was shown in pregnant women with HBsAg > 4 log10 IU/mL.

Abstract
Background To evaluate the efficacy and safety of telbivudine in chronic hepatitis B women during the second and third trimesters of pregnancy. Methods The week 12–34 of pregnant women were screened in this prospective non-intervention study, with HBV DNA > 106 IU/mL and alanine aminotransferase > 50 IU/L. The patients were received telbivudine treatment as a treatment group or without antiviral treatment as a control group. All infants were received recombinant hepatitis B vaccine 10 μg within 12 h of birth, at week 4 and week 24, immunoglobulin G within 12 h of birth and were detected HBV markers at the range from 7 to 12 months after delivery. Results A total of 241 patients were finally enrolled, 139 patients in telbivudine group and 102 patients in control group. HBsAg negative rate of infants was 99.3% (135/136) in telbivudine group and was 91.9% (91/99) in control group after 7 months (P = 0.005), respectively. The incidence of undetectable HBV DNA levels (47.5%) was significantly lower in telbivudine-treated mothers than that in the controls (0%), and 75.5% patients alanine aminotransferase returned to normal in telbivudine group, and 51% in control group at delivery (P < 0.001), respectively. Conclusions Telbivudine can safely reduce mother-to-child transmission in chronic hepatitis B women after 12 weeks of gestation.

Abstract
BACKGROUND/AIMS Mother-to-child transmission (MTCT) is a common transmission mode of hepatitis B virus (HBV). It has been shown that the infection may occur in some infants despite the use of immunoprophylaxis, and many studies have demonstrated the efficacy of antivirals such as lamivudine to reduce such events. MATERIALS AND METHODS A meta-analysis was conducted concerning the efficacy and safety of lamivudine during pregnancy, in the prevention of vertical transmission of HBV infection. Studies were identified by searching various databases up to January 2016 for variations of the following phrase: "lamivudine AND (pregnancy or pregnant) AND (HBV or hepatitis)." Subjects who had received lamivudine were included in the case group, and those who had not were included in the control group. RESULTS Our search identified a total number of 881 citations, of which 25 studies (with a total number of 2,667 pregnant women) were included in the meta-analysis. The analysis showed a significant difference between the seropositive HBsAg infants from the case and control groups (RR= 16.97, 95% confidence interval 8.36-34.45), which is the most critical factor in determining the MTCT of HBV. No significant difference was reported between the prevalence of side effects in the case and control groups. CONCLUSION This meta-analysis strongly suggests the use of lamivudine in the prevention of HBV vertical transmission in carrier pregnant women with the HBV DNA levels greater than 106 copies/mL. And for women with the HBV viral loads lower than 106 copies/mL, we suggest clinicians to examine the use of lamivudine on a case-to-case basis, noting that lamivudine seems to be a safe drug for the mother and the fetus.

Abstract
Nucleo(t)side analogues (NAs) have been administered as adjunctive therapy to interrupt the mother-to-child transmission (MTCT) of hepatitis B virus (HBV). The efficacy and safety of this method remain controversial. A meta-analysis was conducted to evaluate the efficacy and safety of NAs treatment during pregnancy. The differences among different agents and initiation trimesters were analysed. A total of 9228 mother-infant pairs in 59 studies (32 RCTs and 27 non-RCTs) were included in this meta-analysis. NAs significantly reduced the risk of MTCT, as indicated by seropositivity of hepatitis B surface antigen (HBsAg) (risk ratio (RR) = 0.51, 95% confidence interval (CI) 0.45-0.57) and HBV DNA in newborns (RR = 0.22, 95% CI 0.18-0.26). No differences in the efficacy of interrupting HBV MTCT were evident among lamivudine, telbivudine and tenofovir disoproxil fumarate. NA was more effective when administered from the second than from the third trimester as indicated by HBV DNA (RR: the second vs the third 0.08 vs 0.22, P = 0.010), but this effect was not evident as indicated by HBsAg (RR: the second vs the third 0.46 vs 0.53, P = 0.596). Antiviral treatment initiated from the second trimester did not confer a higher risk of safety problems in the newborns compared with treatment from the third trimester, as indicated by weight (P = 0.064), length (P = 0.491) and malformation rate (P = 0.635) of newborns. CONCLUSIONS: Lamivudine, telbivudine and tenofovir disoproxil fumarate are equally effective in blocking HBV MTCT. Antiviral treatment can be applied from the second trimester, without obvious safety concerns.

Abstract
Perinatal transmission of hepatitis B virus (HBV) infection is major contributor to the growing burden of chronic hepatitis B worldwide. Administration of HBV immunoglobulin and HBV vaccination as soon after pregnancy as possible are the mainstay of prevention of perinatal transmission of HBV infection. In women with high viral loads, antiviral prophylaxis also appears to be useful. Lamivudine, telbivudine and tenofovir have been shown to be both safe and effective in this setting but tenofovir is the first-line option due to its low potential for resistance and more favorable safety profile.

Abstract
INTRODUCTION Hepatitis B infection in pregnancy mandates careful monitoring and specialized management according to the phase of hepatitis B infection. Perinatal transmission may be prevented by antiviral therapy in mothers with high viral load and timely immunoprophylaxis of the infant. AREAS COVERED This review focuses on the current first-line therapies for treating hepatitis B in pregnancy, timing of therapy, and prevention of perinatal transmission. Strategies to manage disease at the various phases and potential emerging therapies in phase III of development are also covered. Medline/PubMed and Cochrane databases were searched systematically from 1990 to April 2018 with the relevant articles selected for the review. EXPERT OPINION Universal antenatal screening for hepatitis B and strict immunoprophylaxis for infants form the cornerstones to prevent hepatitis B virus (HBV) perinatal transmission. Tenofovir is the preferred drug for treatment in pregnancy in view of its good efficacy and high barrier to resistance. Most of the data on antivirals are from cohort studies which are prone to bias and more randomized controlled trials (RCTs) are needed to establish the benefits and safety of these drugs in pregnancy. Various novel drugs are in the pipeline which may pave the way for a cure in the near future.

Abstract
PURPOSE This review article focuses on preventing vertical transmission of hepatitis B virus (HBV) among pregnant women living in sub-Saharan Africa (SSA), where disease is endemic and the estimated maternal HBV seroprevalence is >8%. Available interventions that have been studied in low- and middle-income countries are compared in terms of efficacy and effectiveness in clinical practice. Global disease-elimination targets, barriers to HBV-prevention efforts, and critical research gaps are discussed. METHODS A PubMed literature search in February 2018 identified relevant studies of interventions to reduce or prevent the transmission of HBV during pregnancy or in the peripartum period. Studies that focused on interventions that are currently available or could be made available in SSA were included. Trials conducted in SSA and other low-income countries were prioritized, although studies of interventions in middle- and high-income countries were included. FINDINGS Among 127 studies and reports included in the review, 60 included data from SSA. The most cost-effective intervention to reduce HBV infection rates in SSA is timely birth-dose vaccination followed by completion of the 3-dose infant-vaccination series. The identification and treatment of pregnant women with elevated HBV viral load to further reduce the risk for vertical transmission in SSA show promise, but efficacy and tolerability trials in Africa are lacking. IMPLICATIONS Scale-up of currently available tools is required to reach HBV disease-elimination goals in SSA. Many countries in SSA are in the process of rolling out national birth-dose vaccination campaigns; this roll out provides an opportunity to evaluate and improve processes in order to expand coverage. Early antenatal care, promotion of facility deliveries, and increased awareness of HBV prevention are also key components of prevention success. Future studies in SSA should identity an HBV-prevention package that is effective, well tolerated, and feasible and can be administered in the antenatal clinic and tailored to vertical-transmission risk.

Abstract
BACKGROUND Women of childbearing age who have developed chronic hepatitis B (CHB) infection, especially HBeAg-positive highly viraemic pregnant women, are largely responsible for the familial transmission of the infection. Therefore, choosing the most effective and safest antiviral medications to manage pregnant CHB patients is of crucial importance. MATERIALS AND METHODS The PubMed and Scopus databases were searched through September 2017, for all the journal articles possessing original results regarding treatment of CHB pregnant women with any nucleos(t)ide analogue (NA) therapies, including lamivudine (LAM), adefovir (ADV), entecavir (ETV), telbivudine (LdT), and tenofovir (TDF). RESULTS After the primary search, 882 studies were recognized, and updating the searching results, 41 journal articles with original data were investigated, involving 3874 newborn infants from mothers with CHB, and their mothers completed follow-up until the delivery. The most important basic data and results regarding the efficacy of drugs, the rate of vertical transmission, safety issues associated with pairs of mothers and infants, median levels of HBV DNA, breastfeeding data, and rate of rate of vaccination success were collected. Moreover, possible key conclusion, recommendations, and learned lessons were discussed. Among the evaluated NAs, all LAM was efficient and safe. LdT was found to be very effective but had some safety concerns. In contrast, TDF had the advantages of both effectiveness and safety. CONCLUSION According to data in the literature, initiation of TDF at the trimester of pregnancy in combination with immunoprophylaxis to prevent mother-to-child transmission (MTCT) of CHB infection is strongly recommended as well as successful immunization of CHB pregnant women by anti-HBV vaccines.

Abstract
Hepatitis B virus infection is currently the most important cause of chronic viral hepatitis worldwide and is one of the most frequent causes of end-stage liver disease. With the international implementation of the hepatitis B vaccine and combined prophylaxis for infants born to HBsAg(+) mothers, the prevalence of hepatitis B has decreased remarkably. However, intra-uterine transmission has become a critical bottleneck for eliminating hepatitis B infection. The efficacy of nucleos(t)ide analogs on inhibiting hepatitis B replication has been widely confirmed, and the quality of life and the survival of individuals with chronic hepatitis B (CHB) have improved to a great degree. However, with the availability of long-term antiviral treatment and the ever increasing ageing population, renal disorders should be considered when choosing antiviral medicines. The antiviral efficacy and safety of telbivudine (LdT) have been shown in patients with CHB infection, and LdT is approved as a class B drug for pregnancy. Furthermore, the renal protective function of LdT has been demonstrated recently. In this review, we will focus on the efficacy and safety of LdT in gravidas with CHB infection, as well as the renal protective function of LdT in CHB patients. LdT might provide physicians with a solid option for effectively treating patients with CHB, especially gravidas or those either with or at risk of renal impairment.

Abstract
Hepatitis B virus (HBV) infection is a global health problem. Mother-to-child transmission (MTCT, also known as vertical transmission) is the main cause of chronic HBV infection. Although combined active and passive immunization has greatly reduced the vertical transmission of HBV, about 8%-10% of newborns still acquire HBV infection, especially those from hepatitis B e antigen (HBeAg) positive mothers. Previous studies have shown that high levels of HBV DNA and positive HBeAg in serum of pregnant woman may be related to the vertical transmission of HBV. Thus, the prevention of MTCT of HBV has always been a practical question that clinicians must face and urgently needs to solve. However, there is still much controversy over the following aspects: indications of antiviral therapy, drug choice, timing of initiating and ending of antiviral agents, postpartum breast-feeding and so on. This review focuses on the consensus and controversy regarding the prevention of the vertical transmission of HBV.

Abstract
Objective To evaluate the implementation of the 2013 Royal Australian and New Zealand College of Obstetricians and Gynaecologists 'Management of Hepatitis B in Pregnancy' guideline. Methods Retrospective cohort study of the clinical management and obstetric outcomes among hepatitis B virus-positive women in a single tertiary maternity hospital. Women with viral load >200,000 IU/ml were referred to a specialised clinic for consideration of tenofovir disoproxil fumarate therapy to reduce mother to child transmission. Results A total of 11,496 women gave birth during the study period, of which 101 (0.9%) women were hepatitis B virus positive. Viral load was measured in 99 (98%) of 101 hepatitis B virus-positive women; 30 (30%) had a viral load >200,000 IU/ml. Twenty-six women accepted tenofovir disoproxil fumarate; of these, 23 had a successful virological response (viral load <200,000 IU/ml before delivery). Conclusions Adherence to updated management guidelines and patient acceptance of tenofovir disoproxil fumarate in our Australian population were high when provided in the context of a dedicated perinatal service.

Abstract
Chronic hepatitis B virus (HBV) infection due to mother-to-child transmission during the perinatal period remains an important global health problem. Despite standard passive-active immunoprophylaxis with hepatitis B immunoglobulin and hepatitis B vaccine in neonates, up to 8.5% of newborns still acquire HBV infection. Thus, management of chronic HBV during pregnancy and strategies to prevent mother-to-child transmission are important steps in eradicating or reducing the global burden of chronic HBV infection. To date, the management of HBV infection in pregnancy still needs careful attention because of some controversial aspects, including the influence of pregnancy on the course of HBV replication, safety of antiviral prophylaxis with nucleus(t)ide analogs, postpartum flares of hepatitis after delivery, and the safety of breastfeeding. In this review, we highlight these important issues of preventive strategies in the perinatal period.

Abstract
OBJECTIVE To assess the impact of various antiretroviral/antiviral regimens in pregnant women living with HIV or hepatitis B virus (HBV). DESIGN We performed random effects meta-analysis for HIV-related outcomes and network meta-analysis for HBV outcomes, and used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework to assess quality separately for each outcome. DATA SOURCES Embase and Medline to February 2017. ELIGIBILITY CRITERIA For maternal outcomes, we considered randomised controlled trials (RCTs) comparing tenofovir-based regimens with those with alternative nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs). For child outcomes, we included RCTs and comparative observational studies of tenofovir-based regimens versus alternative NRTIs regimens or, for HBV, placebo. RESULTS Ten studies (seven RCTs) met the inclusion criteria for maternal and child outcomes, and an additional 33 studies (12 RCTs) met the inclusion criteria for HBV-specific outcomes. The most common comparison was tenofovir and emtricitabine versus zidovudine and lamivudine. There was no apparent difference between tenofovir-based regimens and alternatives in maternal outcomes, including serious laboratory adverse events (low certainty) and serious clinical adverse events (moderate certainty). There was no difference between NRTIs in vertical transmission of HIV: 1 more per 1000, 8 fewer to 10 more, low certainty; or vertical transmission of HBV: 7 fewer per 1000, 10 fewer to 38 more, moderate certainty. We found moderate certainty evidence that tenofovir/emtricitabine increases the risk of stillbirths and early neonatal mortality (51 more per 1000, 11 more to 150 more) and the risk of early premature delivery at <34 weeks (42 more per 1000, 2 more to 127 more). CONCLUSIONS Tenofovir/emtricitabine is likely to increase stillbirth/early neonatal death and early premature delivery compared with zidovudine/lamivudine, but certainty is low when they are not coprescribed with lopinavir/ritonavir. Other outcomes are likely similar between antiretrovirals. TRIAL REGISTRATION NUMBER PROSPERO CRD42017054392.

Abstract
Vertical transmission (VT) is the primary route of transmission of viral hepatitis in children. The rate of VT ranges from 1-28% with hepatitis B virus (HBV) and 3-15% with hepatitis C virus (HCV). VT for both viruses can occur during the intrauterine or peripartum period. VT of HBV primarily occurs by intrauterine transmission (IUT). Hepatitis B surface antigen is unable to cross the placenta and, therefore, relies on processes like transplacental leakage, placental infection, cellular transmission by peripheral blood mononuclear cells, and germline transmission. HCV can also infect the fetus by IUT. Both viruses also have the potential for transmission during delivery, when there is increase chance of maternal-fetal blood exposure. HBV and HCV share some common risk factors for VT, including maternal viral load, human immunodeficiency virus co-infection and neonatal sex. Prevention of VT differs greatly between HBV and HCV. There are several alternatives for prevention of HBV VT, including antiviral medications during the third trimester of pregnancy and HBV vaccine, as well as hepatitis B immunoglobulin administration to infants post-partum. In contrast, there are no preventative interventions available for HCV. Despite these differences, the key to prevention with both viruses is screening women prior to and during pregnancy.

Abstract
BACKGROUND & AIMS Antiviral drugs are safe and effective in the third trimester to prevent intrauterine transmission of hepatitis B virus, and are recommended for hepatitis B virus (HBV) infected gravid mothers (between weeks 28 and 32) with high viral load, followed by postnatal hepatitis B immunization in the newborn. We estimated the comparative efficacy of antiviral drugs for prevention of vertical transmission of HBV, through a network meta-analysis of clinical trials. METHODS We conducted a comprehensive search of MEDLINE, EMBASE and published proceedings from major liver meetings from January 1980 to November 2014. We conducted pair-wise meta-analyses and Bayesian framework using Markov chain Monte Carlo methods, combining direct and indirect evidence for any given pair of treatments. RESULTS Seventeen clinical trials involving 2764 newborns of hepatitis B surface antigen seropositive mothers were eligible for analysis. There were no clinical trials involving tenofovir or entecavir. On pair-wise meta-analyses, telbivudine (hazard ratio, HR 0.12, 95% confidence interval (CI) 0.04-0.37; I(2) = 0%), and Lamivudine (HR 0.40, 95% CI 0.24-0.65; I(2) = 0%), were more effective than placebo in reducing vertical transmission of HBV in high viremic hepatitis B e antigen (HBeAg)-positive chronic Hepatitis B Chinese patients. Sensitivity analyses limited to studies with HBeAg seropositive mothers revealed similar results. CONCLUSIONS Based on a Bayesian network meta-analysis of clinical trials, combining direct and indirect treatment comparisons, telbivudine appears to be more effective than Lamivudine for preventing vertical transmission of HBV infection. Trials assessing the efficacy of tenofovir or entecavir compared to placebo or other antiviral drugs are lacking.

Abstract
AIM To achieve an evidence-based conclusion regarding the safety and efficacy of telbivudine during pregnancy. METHODS A pooled analysis of data from a literature search reported 1739 pregnancy outcomes (1673 live births) from 1725 non-overlapping pregnant women treated with telbivudine. The prevalence of live birth defects (3.6/1000) was similar to that of the non-antiviral controls (3.0/1000) and not increased as compared with overall prevalence (14.5 to 60/1000). No target organ toxicity was identified. The prevalence of spontaneous abortion in pregnant women treated with telbivudine (4.2/1000) was not increased compared with the overall prevalence (16/1000). The mother-to-child transmission rate was significantly reduced in pregnant women treated with telbivudine (0.70%) compared to those treated with the non-antiviral controls (11.9%; P < 0.0001) or compared to the historical rates of hepatitis B virus (HBV)-infected population without antiviral treatment (10%-15%). RESULTS Cumulatively 489 pregnancy cases have been reported in the telbivudine pharmacovigilance database (with a cut-off date 31 August 2014), of those, 308 had known pregnancy outcomes with 249 cases of live births (239 cases of live birth without congenital anomaly and 10 cases of live birth with congenital anomaly). In the latest antiretroviral pregnancy registry report (1 January 1989 through 31 January 2015) of 27 patients exposed to telbivudine during pregnancy (18, 6 and 3 during first, second and third trimester, respectively) 19 live births were reported and there were no cases of birth defects reported. CONCLUSION Telbivudine treatment during pregnancy presents a favorable safety profile without increased rates of live birth defects, spontaneous abortion or elective termination, or fetal/neonatal toxicity. Exposure to telbivudine in the first, second and third trimester of pregnancy has been shown to significantly reduce the risk of HBV transmission from mother to child on the basis of standard immune prophylaxis procedure.

Abstract
Background. Hepatitis B virus (HBV) infections are perinatally transmitted from chronically infected mothers. Supplemental antiviral therapy during late pregnancy with lamivudine (LAM), telbivudine (LdT), or tenofovir (TDF) can substantially reduce perinatal HBV transmission compared to postnatal immunoprophylaxis (IP) alone. However, the cost-effectiveness of these measures is not clear. Aim. This study evaluated the cost-effectiveness from a societal perspective of supplemental antiviral agents for preventing perinatal HBV transmission in mothers with high viral load (>6 log10 copies/mL). Methods. A systematic review and network meta-analysis were performed for the risk of perinatal HBV transmission with antiviral therapies. A decision analysis was conducted to evaluate the clinical and economic outcomes in China of four competing strategies: postnatal IP alone (strategy IP), or in combination with perinatal LAM (strategy LAM + IP), LdT (strategy LdT + IP), or TDF (strategy TDF + IP). Antiviral treatments were administered from week 28 of gestation to 4 weeks after birth. Outcomes included treatment-related costs, number of infections, and quality-adjusted life years (QALYs). One- and two-way sensitivity analyses were performed to identify influential clinical and cost-related variables. Probabilistic sensitivity analyses were used to estimate the probabilities of being cost-effective for each strategy. Results. LdT + IP and TDF + IP averted the most infections and HBV-related deaths, and gained the most QALYs. IP and TDF + IP were dominated as they resulted in less or equal QALYs with higher associated costs. LdT + IP had an incremental $2,891 per QALY gained (95% CI [$932–$20,372]) compared to LAM + IP (GDP per capita for China in 2013 was $6,800). One-way sensitivity analyses showed that the cost-effectiveness of LdT + IP was only sensitive to the relative risk of HBV transmission comparing LdT + IP with LAM + IP. Probabilistic sensitivity analyses demonstrated that LdT + IP was cost-effective in most cases across willingness-to-pay range of $6,800 ∼ $20,400 per QALY gained. Conclusions. For pregnant HBV-infected women with high levels of viremia, supplemental use of LdT during late pregnancy combined with postnatal IP for infants is cost-effective in China.

Abstract
AIM We aimed to investigate the efficacy and safety of telbivudine (LdT) on the intervention of mother-to-child transmission (MTCT) in different trimesters of pregnant women with high viral loads. METHODS In this prospective cohort study, 160 cases of mothers with high viral loads were included. Eighty-two subjects received 600 mg/day LdT therapy. Fifty of them started LdT therapy before the third trimester of gestation, including 17 cases before pregnancy, nine and 24 cases in the first and second trimesters of pregnancy, respectively. The other 32 cases started LdT in the third trimester of gestation. Control pregnant women (78 cases) did not take LdT therapy. MTCT rate was determined by hepatitis B surface antigen (HBsAg) and hepatitis B virus (HBV) DNA data of infants at the 51st week post-partum. Adverse events were also evaluated throughout the study. RESULTS One hundred and sixty infants were born from 160 pregnant women. Both LdT-treated groups displayed a marked decline in HBV DNA levels from the beginning to delivery. Positive rate of serum HBsAg in infants born from the above two groups of mothers were 0% and 3.1%, respectively, which was significantly lower than that in the untreated controls (24.4%). The incidence of detectable HBV DNA levels was significantly lower in infants born to LdT-treated mothers than in the controls (16.7%) at the 51st week post-partum. No infant had birth defects. No severe adverse event or complication were observed in LdT-treated mothers or infants followed until the 51st week post-partum. CONCLUSION The earlier application of LdT during pregnancy, the better preventive effects it offered on MTCT.

Abstract
Worldwide, some 240 million people have chronic hepatitis B virus (HBV), with the highest rates of infection in Africa and Asia. Our understanding of the natural history of HBV infection and the potential for therapy of the resultant disease is continuously improving. New data have become available since the previous APASL guidelines for management of HBV infection were published in 2012. The objective of this manuscript is to update the recommendations for the optimal management of chronic HBV infection. The 2015 guidelines were developed by a panel of Asian experts chosen by the APASL. The clinical practice guidelines are based on evidence from existing publications or, if evidence was unavailable, on the experts' personal experience and opinion after deliberations. Manuscripts and abstracts of important meetings published through January 2015 have been evaluated. This guideline covers the full spectrum of care of patients infected with hepatitis B, including new terminology, natural history, screening, vaccination, counseling, diagnosis, assessment of the stage of liver disease, the indications, timing, choice and duration of single or combination of antiviral drugs, screening for HCC, management in special situations like childhood, pregnancy, coinfections, renal impairment and pre- and post-liver transplant, and policy guidelines. However, areas of uncertainty still exist, and clinicians, patients, and public health authorities must therefore continue to make choices on the basis of the evolving evidence. The final clinical practice guidelines and recommendations are presented here, along with the relevant background information.

Antiviral therapy in chronic hepatitis B viral infection during pregnancy: A systematic review and meta-analysis. Hepatology 2016; 63:319-33. [PMID: 26565396 DOI: 10.1002/hep.28302] [Citation(s) in RCA: 224] [Impact Index Per Article: 28.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2015] [Accepted: 10/15/2015] [Indexed: 12/11/2022]
Abstract
UNLABELLED Perinatal or mother-to-child transmission (MTCT) of hepatitis B virus (HBV) remains the major risk factor for chronic HBV infection worldwide. In addition to hepatitis B immune globulin and vaccination, oral antiviral therapies in highly viremic mothers can further decrease MTCT of HBV. We conducted a systematic review and meta-analysis to synthesize the evidence on the efficacy and maternal and fetal safety of antiviral therapy during pregnancy. A protocol was developed by the American Association for the Study of Liver Diseases guideline writing committee. We searched multiple databases for controlled studies that enrolled pregnant women with chronic HBV infection treated with antiviral therapy. Outcomes of interest were reduction of MTCT and adverse outcomes to mothers and newborns. Study selection and data extraction were done by pairs of independent reviewers. We included 26 studies that enrolled 3622 pregnant women. Antiviral therapy reduced MTCT, as defined by infant hepatitis B surface antigen seropositivity (risk ratio = 0.3, 95% confidence interval 0.2-0.4) or infant HBV DNA seropositivity (risk ratio = 0.3, 95% confidence interval 0.2-0.5) at 6-12 months. No significant differences were found in the congenital malformation rate, prematurity rate, and Apgar scores. Compared to control, lamivudine or telbivudine improved maternal HBV DNA suppression at delivery and during 4-8 weeks' postpartum follow-up. Tenofovir showed improvement in HBV DNA suppression at delivery. No significant differences were found in postpartum hemorrhage, cesarean section, and elevated creatinine kinase rates. CONCLUSIONS Antiviral therapy improves HBV suppression and reduces MTCT in women with chronic HBV infection with high viral load compared to the use of hepatitis B immunoglobulin and vaccination alone; the use of telbivudine, lamivudine, and tenofovir appears to be safe in pregnancy with no increased adverse maternal or fetal outcome.

Abstract
UNLABELLED The efficacy and safety of maternal tenofovir disoproxil fumarate (TDF) in reducing mother-to-infant hepatitis B virus (HBV) transmissions is not clearly understood. We conducted a prospective, multicenter trial and enrolled 118 hepatitis B surface antigen (HBsAg)- and hepatitis B e antigen-positive pregnant women with HBV DNA ≥7.5 log10 IU/mL. The mothers received no medication (control group, n = 56, HBV DNA 8.22 ± 0.39 log10 IU/mL) or TDF 300 mg daily (TDF group, n = 62, HBV DNA 8.18 ± 0.47 log10 IU/mL) from 30-32 weeks of gestation until 1 month postpartum. Primary outcome was infant HBsAg at 6 months old. At delivery, the TDF group had lower maternal HBV DNA levels (4.29 ± 0.93 versus 8.10 ± 0.56 log10 IU/mL, P < 0.0001). Of the 121/123 newborns, the TDF group had lower rates of HBV DNA positivity at birth (6.15% versus 31.48%, P = 0.0003) and HBsAg positivity at 6 months old (1.54% versus 10.71%, P = 0.0481). Multivariate analysis revealed that the TDF group had lower risk (odds ratio = 0.10, P = 0.0434) and amniocentesis was associated with higher risk (odds ratio 6.82, P = 0.0220) of infant HBsAg positivity. The TDF group had less incidence of maternal alanine aminotransferase (ALT) levels above two times the upper limit of normal for ≥3 months (3.23% versus 14.29%, P = 0.0455), a lesser extent of postpartum elevations of ALT (P = 0.007), and a lower rate of ALT over five times the upper limit of normal (1.64% versus 14.29%, P = 0.0135) at 2 months postpartum. Maternal creatinine and creatinine kinase levels, rates of congenital anomaly, premature birth, and growth parameters in infants were comparable in both groups. At 12 months, one TDF-group child newly developed HBsAg positivity, presumably due to postnatal infection and inefficient humoral responses to vaccines. CONCLUSIONS Treatment with TDF for highly viremic mothers decreased infant HBV DNA at birth and infant HBsAg positivity at 6 months and ameliorated maternal ALT elevations.

Abstract
For two decades, hepatitis B vaccine has been integrated into national routine childhood vaccination programs in almost all countries. The prevalence of HBsAg has decreased in children worldwide. However, there are children who miss the benefit of hepatitis B vaccine in some regions and countries. Long-term follow-up studies have revealed the clinical outcomes of chronic hepatitis B virus infection in children. A small percentage of chronically infected children develop liver cirrhosis and hepatocellular carcinoma. However, it is controversial who should be treated and when antiviral treatment should be initiated in children. Compared with adult studies, the data are insufficient to evaluate the pathogenesis of hepatitis B infection and the efficacy of antiviral treatment in childhood. New antiviral drugs have been approved for children and adults. Also, oral antiviral drugs are administered to pregnant women to reduce the hepatitis B virus mother-to-child transmission rate.

Abstract
AIM: To dynamicly monitor serum hepatitis B surface antigen (HBsAg) levels in chronic hepatitis B patients receiving entecavir (ETV) to explore whether serum HBsAg level can predict the therapeutic effect of antiviral treatment.
METHODS: Ninety chronic hepatitis B patients were selected strictly and given ETV for one year. HBsAg and hepatitis B virus (HBV) DNA levels were determined at 0, 3, 6, 9, and 12 mo. The t-test, Pearson correlation, and receiver operating characteristic (ROC) curve were used for analysis.
RESULTS: A total of 52 (57.78%) patients showed a response to ETV treatment, and 38 (42.22%) did not. Age was significantly greater in the response group than in the non-response group, while HBsAg and HBV DNA levels were significantly lower in the response group (P < 0.05). HBsAg and HBV DNA levels were decreased in both groups, and the decreases were more significant in the response group (P < 0.05). HBsAg levels were significantly correlated with HBV DNA levels (r = 0.5353, P < 0.0001). The area under the ROC curve was lowest at 3 mo after treatment, followed by at baseline, at 6 mo, at 9 mo, and at 12 mo after treatment.
CONCLUSION: Serum HBsAg levels in patients with chronic hepatitis B can be used as a predictor of response to antiviral treatment.
