Immediate postpartum cessation of tenofovir did not increase risk of virological or clinical relapse in highly viremic pregnant mothers with chronic hepatitis B infection. JHEP Rep 2024; 6:101050. [PMID: 38699531 PMCID: PMC11063518 DOI: 10.1016/j.jhepr.2024.101050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2023] [Revised: 02/16/2024] [Accepted: 02/21/2024] [Indexed: 05/05/2024] Open
Abstract
Background & Aims Peripartum prophylaxis (PP) with tenofovir disoproxil fumarate (TDF) is the standard of care to prevent mother-to-child transmission of chronic hepatitis B (CHB) infection in mothers who are highly viremic. We investigated the maternal and infant outcomes in a large Chinese cohort of TDF-treated CHB pregnant participants. Methods In this prospective study, treatment-naive mothers with CHB and highly viremic (HBV DNA ≥200,000 IU/ml) but without cirrhosis were treated with TDF at 24-28 weeks of pregnancy. In accordance with Chinese CHB guidelines, TDF was stopped at delivery or ≥4 weeks postpartum. Serum HBV DNA and alanine aminotransferase were monitored every 6-8 weeks to determine virological relapse (VR). Infants received standard neonatal immunization, and HBV serology was checked at 7-12 months of age. Results Among 330 participants recruited (median age 30, 82.7% HBeAg+, median HBV DNA 7.82 log IU/ml), TDF was stopped at delivery in 66.4% and at ≥4 weeks in 33.6%. VR was observed in 98.3%, among which 11.6% were retreated with TDF. Timing of TDF cessation did not alter the risk of VR (99.0 vs. 96.9%), clinical relapse (19.5 vs. 14.3%), or retreatment (12.6 vs. 10.1%) (all p > 0.05). A similar proportion of patients developed alanine aminotransferase flare five times (1.1 vs. 2.1%; p = 0.464) and 10 times (0.5 vs. 0%; p = 0.669) above the upper limit of normal (ULN) in the early withdrawal and late withdrawal groups, respectively. No infants developed HBsAg-positivity. Conclusions PP-TDF and neonatal immunization were highly effective in preventing mother-to-child transmission of HBV in mothers who are highly viremic. Timing of cessation of PP-TDF did not affect the risk of VR or retreatment. Impact and Implications In pregnant mothers with chronic hepatitis B infection who are started on peripartum tenofovir to prevent mother-to-child-transmission (MTCT), the optimal timing for antiviral withdrawal during the postpartum period remains unknown. This prospective study demonstrates that stopping tenofovir immediately at delivery, compared with longer treatment duration of tenofovir, did not lead to an increased risk of virological relapse, retreatment, or transmission of the virus to the baby. Shortening the duration of peripartum antiviral prophylaxis from 12 weeks to immediately after delivery can be considered. The immediate withdrawal of peripartum tenofovir, combined with standard neonatal immunization schemes, is 100% effective in preventing MTCT among pregnant mothers with CHB who are highly viremic, with a high rate of vaccine response in infants.

Abstract
In 2016, the World Health Organization released a plan to eliminate viral hepatitis as a public health threat by 2030. For Canada to achieve the recommended decreases in HBV- and HCV-related new diagnoses and deaths, an increase in services is urgently required. Identifying those at risk of, or who have acquired HBV and HCV, remains a challenge, especially with the emergence of new priority populations such as pregnant persons and children. Importantly, prenatal, and pediatric care are times when individuals are often already engaged with the healthcare system, leading to the potential for opportunistic or co-localized care and interventions. At present, Canada may not be maximizing all available virologic tools that could lead to increases in prevention, identification, improved management, or even cure. Here, we describe the continuum of care that includes preconception, prenatal, postpartum, and pediatric stages; and identify current global and Canadian recommendations, findings, and opportunities for improvement.

Abstract
Hepatitis B virus (HBV) is a global health problem. Vertical transmission of HBV from HBV surface antigen (HBsAg)-positive mothers to their infants is the most common cause of HBV infection worldwide. The use of passive-active immunoprophylaxis is >90% effective in reducing the risk of vertical transmission, but immunoprophylaxis failure can occur in infants born to mothers with high viraemia. Thus, it is recommended that pregnant women with HBV-DNA level >200 000 IU/ml receive nucleos(t)ide analogue (NA) treatment [i.e. tenofovir disoproxil fumarate (TDF), lamivudine or telbivudine] during third trimester to prevent infant immunoprophylaxis failure. TDF is recommended as the first-line therapy based on available data on efficacy, safety and resistance profile. However, maternal immunological reconstitution following parturition can increase immune-mediated flares to viral antigens that is potentially exacerbated following TDF withdrawal. In this article, we review available data on the efficacy and safety of TDF administration to prevent HBV mother-to-child transmission. We also discuss changes in maternal viral markers [i.e. HBV-DNA, HBV e antigen and HBsAg] and alanine aminotransferase during follow-up post-partum in mothers received NA to prevent HBV vertical transmission.

Immunoglobulin-free strategy to prevent HBV mother-to-child transmission in Cambodia (TA-PROHM): a single-arm, multicentre, phase 4 trial. THE LANCET. INFECTIOUS DISEASES 2022; 22:1181-1190. [PMID: 35643089 DOI: 10.1016/s1473-3099(22)00206-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Revised: 02/12/2022] [Accepted: 03/10/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Prevention of mother-to-child transmission (MTCT) of hepatitis B virus (HBV) is based on administration of vaccine and immunoglobulins (HBIg) to newborns at birth and maternal antiviral prophylaxis for those with an HBV-DNA viral load of at 5·3 log10 IU/mL or more. Many low-income and middle-income countries face difficulty in accessing HBIg and HBV-DNA quantification. The aim of this study was to evaluate the effectiveness of an HBIg-free strategy to prevent MTCT of HBV. METHODS TA-PROHM was a single-arm, multicentre, phase 4 trial done in five maternity units in Cambodia. Pregnant women who were positive for hepatitis B surface antigen (HBsAg), aged 18 years or older were included. Women who were HCV or HIV positive, had creatinine clearance of less than 30 mL/min, severe gravid disease, and planned to give birth outside the study sites were excluded. From Oct 4, 2017, to Jan 9, 2019, HBsAg positive pregnant women who tested positive for hepatitis B e antigen (HBeAg) with a rapid diagnostic test were eligible to receive tenofovir disoproxil fumarate. From Jan 9, 2019, women who were HBeAg negative with an alanine aminotransferase concentration of ≥40 IU/L were also eligible to receive tenofovir disoproxil fumarate. Women in the tenofovir disoproxil fumarate eligible group received 300 mg of tenofovir disoproxil fumarate orally once a day from the 24th week of gestation until 6 weeks postpartum. The primary outcome was the overall proportion of infants who were HBsAg positive at 6 months of life, confirmed by positive HBV DNA quantification. For the primary outcome, the proportion (95% CI) of infants with HBsAg at 6 months was stratified according to infant's HBIg status, duration of maternal tenofovir disoproxil fumarate treatment (>4 weeks and ≤4 weeks), and study period (before and after the change in therapeutic algorithm) and was measured in a modified intention-to-treat analysis, which excluded infants lost to follow-up or who were withdrawn before 6 months. The study is registered with ClinicalTrials.gov, NCT02937779. FINDINGS From Oct 4, 2017, to Nov 27, 2020, 21 251 pregnant women were screened for HBsAg, of whom 1194 (6%) were enrolled in the study: 338 (28%) were eligible to receive tenofovir disoproxil fumarate. For the tenofovir disoproxil fumarate eligible group, four (1% [95% CI 0·34-3·20]) of 317 infants had HBV infection at 6 months; in the subgroup of 271 children who did not receive HBIg, four (1% [0·40-3·74]) had HBV infection at 6 months. In absence of HBIg, MTCT HBV transmission occurred in none (0% [0-1·61]) of 227 women who received tenofovir disoproxil fumarate for more than 4 weeks before giving birth and three (8% [1·75-22·47]) of 36 women who received tenofovir disoproxil fumarate for less than 4 weeks. In the tenofovir disoproxil fumarate ineligible group, seven (1% [0·40-2·02]) of 712 infants had HBV infection at 6 months; in the subgroup of 567 children who did not receive HBIg, six (1% [0·39-2·30]) had HBV infection at 6 months. INTERPRETATION An immunoglobulin-free strategy using an HBeAg rapid diagnosis test and alanine aminotransferase-based algorithm to assess eligibility for tenofovir, is effective at preventing MTCT of HBV when tenofovir was initiated at least 4 weeks before birth.

Antiviral Therapy for Prevention of Perinatal Hepatitis B Virus Transmission Reduces the Incidence of Postpartum Hepatitis Flare. BIOMED RESEARCH INTERNATIONAL 2022; 2022:7046955. [PMID: 35860799 PMCID: PMC9293540 DOI: 10.1155/2022/7046955] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 06/11/2022] [Accepted: 06/20/2022] [Indexed: 11/23/2022]
Abstract
Background: Currently, there are few studies on the effect of prophylactic anti-hepatitis B virus (HBV) therapy (AVT) for mother-to-child transmission during pregnancy on postpartum hepatitis flare (PHF) and the risk factors for postpartum hepatitis flare in women with chronic hepatitis B infection. Aim: To analyze the effect of AVT on the postpartum hepatitis flare and risk factors related to postpartum hepatitis flare. Methods: This study retrospectively enrolled hepatitis B surface antigen (HBsAg)-positive and hepatitis B e antigen (HBeAg)-positive women with HBV DNA ≥ 106 IU/mL. Six hundred fourteen pregnant women were included: 444 in the anti-HBV therapy group (T-G) and 170 in the control group (C-G). To analyze the risk factors, women with alanine aminotransferase (ALT) flare (ALT > 40 U/L) were assigned to the PHF group (PHF-G, n = 355), and all the others were assigned to a non-PHF group (NPHF-G, n = 259). Results: At 6 weeks postpartum, ALT and AST levels were higher, and ALB levels were lower in the C-G than those in T-G (P < 0.05). Also, ALT (at baseline, pregnancy 32nd and 36th, intrapartum), AST (at pregnancy 32nd and 36th week, and intrapartum), HBcAb (at baseline, intrapartum), and HBV DNA (at intrapartum) of PHF-G were significantly higher than those of NPHF-G (P < 0.05). Multivariate analysis showed that ALT (OR = 1.067, P < 0.001) and HBcAb (OR = 1.213, P ≤ 0.001) in pregnant women were risk factors for PHF. The prophylactic anti-HBV for the prevention of perinatal HBV transmission (OR = 0.357, P < 0.001) was the protective factor for PHF. Conclusion: Pregnant women with prophylactic anti-HBV during the third trimester of pregnancy had a lower incidence of postpartum hepatitis flare, especially a lower risk of serious hepatitis flare. ALT and HBcAb in pregnant women were risk factors for PHF. Women infected with HBV should be closely monitored ALT during pregnancy and postpartum.

Abstract
Sexual dimorphism in infectious diseases refers to the different infection susceptibilities and outcomes between males and females, and has been described for many pathogens, including hepatitis B virus (HBV). HBV is a substantial global health problem, with close to 300 million people chronically infected, and accounting for a million deaths each year, with an urgent need for enhanced interventions to support progress towards elimination goals. Sexual dimorphism has a strong influence in HBV infection, with males more likely to be exposed, to develop chronic infection, and to suffer from complications including cirrhosis and hepatocellular carcinoma (HCC) compared to females. Different outcomes are driven by differential immune responses, sexual dimorphism of the liver, and androgen response elements in the HBV genome. The impact of sex may also vary with age, with changes at puberty and influences of menarche, pregnancy and menopause in females. In addition, gender has complex influences on education, beliefs, behaviour and access to / engagement with healthcare services, which may contribute to differences in diagnosis and treatment. Interplay between these complex factors, alongside other attributes of host, virus and the environment, accounts for different outcomes of infection. However, gaps remain in our understanding of sexual dimorphism in HBV, and little effort has previously been made to harness this knowledge for translational gains. In this review, we assimilate human and animal data to consider the mechanism, outcomes and impact of sexual dimorphism, and consider how these insights can be used to inform advances in surveillance, treatment and prevention for HBV infection.

Abstract
Hepatitis B virus (HBV) infection still remains a major public health issue in the Asia-Pacific region. Most of the burden of HBV-related disease results from infections acquired in infancy through perinatal or early childhood exposure to HBV in Asia-Pacific. Hepatitis B during pregnancy presents unique management issues for both the mother and fetus. These APASL guidelines provide a comprehensive review and recommendations based on available evidence in the literature, for the management of females with HBV infection through every stage of pregnancy and postpartum. These also address the concerns, management challenges, and required follow-up of children born to hepatitis B-positive mothers.

HBV is a substantial global health problem, with close to 300 million people infected, and accounting for a million deaths each year, with an urgent need for enhanced interventions to support progress towards elimination goals. Sexual dimorphism has a strong influence in HBV infection, with males more likely to be exposed, to develop chronic infection, and to suffer from complications including cirrhosis and hepatocellular carcinoma (HCC) compared to females. Different outcomes are driven by differential immune responses, sexual dimorphism of the liver, and androgen response elements in the HBV genome. The impact of sex may also vary with age, with changes at puberty and influences of menarche, pregnancy and menopause in females. In addition, gender has complex influences on education, beliefs, behaviour and access to / engagement with healthcare services, which may contribute to differences in diagnosis and treatment. Interplay between these complex factors, alongside other attributes of host, virus and the environment, accounts for different outcomes of infection. However, gaps remain in our understanding of sexual dimorphism in HBV, and little effort has previously been made to harness this knowledge for translational gains. In this review, we assimilate human and animal data to consider the mechanism, outcomes and impact of sexual dimorphism, considering how these insights can be used to inform advances in surveillance, treatment and prevention for HBV infection.

Abstract
Chronic liver disease poses various challenges for women of reproductive age. Cirrhosis, particularly if decompensated, and liver transplantation may impact gestation and perinatal outcomes. Tailored management of underlying liver disease is critical to optimize maternal and fetal wellbeing. Early education, timely intervention, close monitoring, and a multidisciplinary approach are key elements required to minimize complications and increase chances of a safe and successful pregnancy. In this review, we focus on the pregnancy-related implications of chronic liver disease and liver transplantation on women of reproductive age and highlight disease-specific management considerations.

Abstract
BACKGROUND To evaluate the protective efficacy of a hepatitis B (HB) vaccination program in Taiwan among high-risk children. MATERIAL AND METHODS Children born to HBeAg-positive mothers from 2001 to 2010 were invited back. Blood samples for hepatitis B virus (HBV) seromarkers were taken and the children underwent hepatobiliary ultrasonography. Perinatal factors including delivery mode and vaccination history were collected from their medical records. According to the results of HBV serological markers, the children were initially classified into five groups: HBV naïve, HB vaccine responder, HBsAg carrier, recovered from HBV infection, and anti-HBc-positive alone. Children in the HBV naïve and anti-HBc-positive alone groups who presented with an anamnestic response after a booster HB vaccine were re-assigned to the vaccine responder and recovered from infection groups, respectively. RESULTS All of the 196 enrolled children received postnatal hepatitis B immunoglobulin (HBIG) and HB vaccinations, of whom one was HBV naïve (0.5%), 109 were vaccine responders (55.6%), 21 were carriers (10.7%), and 65 recovered from infection (33.2%). Among the 21 carriers, 14 (66.7%) presented in the immunotolerant phase. Cesarean section was the only significant perinatal factor between the carriers (5.3%) and those who recovered from infection (37.7%) (p=0.007). CONCLUSIONS In this study, there was a 43.9% HBV infection rate and 10.7% HBsAg carrier rate in high-risk Taiwanese children even after receiving HBIG and HB vaccinations. Cesarean section may protect newborns from becoming HBsAg carriers, while HBV genotype and time of HBIG injection did not contribute to the HBV carrier rate.

Mother To Infant Transmission Of Hepatitis B Virus In The Face Of Neonatal Immunisation Is Not Necessarily Primary Vaccine Failure. Clin Infect Dis 2021; 74:1151-1157.

Abstract
BACKGROUND Surveillance programmes undertaken in infants born to hepatitis B virus (HBV) infected mothers provide an opportunity to analyse virological markers from the neonate and early infancy. These data inform on mechanisms of HBV transmission and how available interventions can be better utilised for control of HBV infections arising at the mother/child interface. METHODS Retrospective analysis of HBV serological markers was undertaken in Dried Blood Spots collected from infants born to HBV-infected mothers. In addition, molecular analysis was performed in newborn blood spot cards, collected after birth, from infants identified as HBV-infected despite receiving prophylaxis. RESULTS Perinatal exposure could not account for all transmissions with at least one quarter (22%) of infants already infected in utero. All harboured a wild type HBsAg, with identical sequences noted in the neonatal and early infancy samples. In contrast, in infants infected perinatally (43%), selection of viruses harbouring amino acid changes in the HBsAg were common (80% of sequences) and divergent from the linked maternal sample. CONCLUSION Currently considered to represent vaccine failure, it is likely that a proportion of HBV infections result from in utero acquisition. These infections are unlikely to be susceptible to post-natal prophylaxis and current recommendations for maternal antiviral treatment may be too late to prevent transmission. Consideration should be given to the earlier use of antivirals during gestation to reduce the risk of intrauterine transmission together with completion of the immunisation schedule also to reduce the perinatal risk of HBV transmission.

Abstract
Chronic hepatitis B (CHB) is a significant public health problem worldwide. The aim of the present review is to summarize the actual trends in the management of CHB in pregnant women. The prevalence of hepatitis B virus (HBV) infection in pregnant women is usually comparable to that in the general population in the corresponding geographic area. All women have to be screened for hepatitis B surface antigen (HBsAg) during pregnancy. Additional examinations of pregnant women with CHB may include maternal hepatitis B e antigen, HBV viral load, alanine aminotransferase level, and HBsAg level. The management of pregnancy depends on the phase of the HBV infection, which has to be determined before pregnancy. In women of childbearing age with CHB, antiviral therapy can pursue two main goals: Treatment of active CHB, and vertical transmission prevention. During pregnancy, tenofovir is the drug of choice in both cases. A combination of hepatitis B immunoglobulin and vaccine against hepatitis B should be administered within the first 12 h to all infants born to mothers with CHB. In such cases, there are no contraindications to breastfeeding.

Abstract
AIM This study aimed to explore the benefits of different antiviral regimens in pregnant women with hepatitis B virus (HBV) infection in an attempt to provide scientific reference for clinically relevant interventions. METHODS The study cohort comprised 64 pregnant women with HBV infection who presented to our hospital from May 2018 to July 2020. The women were grouped according to the treatment administered: a control group consisting of 32 pregnant women who received routine intervention and an observation group consisting of 32 pregnant women who received routine intervention plus tenofovir disoproxil fumarate (TDF) tablets. The two groups were compared in terms of liver function; HBV load (HBV DNA); neonatal characteristics (hepatitis B surface antigen and HBV DNA positivity); levels of interleukin (IL)-2, IL-4, and IL-6; neonatal growth and development; Apgar scores; incidence of adverse events; and incidence of maternal adverse effects during treatment. RESULTS The observation group had lower levels of alanine aminotransferase, glutamic acid aminotransferase, IL-4, IL-6, and HBV DNA and higher levels of IL-2 than the control group after 1 month of treatment (p < 0.05). There was no significant difference in the incidence of adverse events between the two groups (p > 0.05). CONCLUSION The administration of TDF tablets significantly reduced the HBV DNA levels and did not increase the physiological burden or adverse effects in pregnant women with HBV infection.

Abstract
BACKGROUND: The greatest risk of chronic hepatitis B (CHB) is from mother-to-child transmission. Approximately 20% of individuals in sub-Saharan Africa are hepatitis B virus (HBV) surface antigen–positive (HBsAg+), but the prevalence of occult hepatitis B (OHB) is unknown. Aim: This study investigated CHB and OHB prevalence and viral variants in a cohort of pregnant women in Gondor, Ethiopia. METHODS: Patients were prospectively recruited from the University of Gondar Hospital ( N = 200; median age 27 [inter-quartile range] 8.3y) from March through June 2016. Data were collected using an investigator-administered questionnaire. Plasma was tested for HBsAg and HBV core antibody (anti-HBc), and HBV genotype and presence of HBV variants (ie, vaccine escape mutants [VEMs]) were determined by polymerase chain reaction, Sanger sequencing, and phylogenetic analysis. RESULTS: Of women tested, 1% (2/200) were HBsAg+; 26.8% (47/182) of HBsAg-negative patients were anti-HBc+, of whom 37/47 (78.7%) had detectable HBV DNA. The overall rate of OHB was 20.3%. Both HBsAg+ cases were HBV genotype D, and 36/37 (97.3%) of OHB individuals were genotype D. None carried VEM, but both HBsAg+ cases and 32/37 (86.5%) of the OHB cases showed lamivudine-resistant mutations. CONCLUSIONS: Twenty-seven percent of pregnant women in this cohort showed evidence of CHB or prior HBV exposure (ie, HBsAg+ or anti-HBc+) and clinically relevant HBV variants. Data from this single-centre study suggests high HBV prevalence, reinforcing the World Health Organization’s recommendation for universal prenatal HBV screening and infant vaccination.

Abstract
Chronic Hepatitis B Virus (HBV) infection poses a significant global health burden. Although, effective treatment and vaccinations against HBV are available, challenges still exist, particularly in the development of curative therapies. The dynamic nature and unique features of HBV such as viral variants, integration of HBV DNA into host chromosomes, and extrahepatic reservoirs are considerations towards understanding the virus biology and developing improved anti-HBV treatments. In this review, we highlight the importance of these viral characteristics in the context of treatment and oncogenesis. Viral genotype and genetic variants can serve as important predictive factors for therapeutic response and outcomes in addition to oncogenic risk. HBV integration, particularly in coding genes, is implicated in the development of hepatocellular carcinoma. Furthermore, we will discuss emerging research that has identified various HBV nucleic acids and infection markers within extrahepatic sites (lymphoid cells). Intriguingly, the presence of hepatocellular carcinoma (HCC)-associated HBV variants and viral integration within the lymphoid cells may contribute towards the development of extrahepatic malignancies. Improved understanding of these HBV characteristics will enhance the development of a cure for chronic HBV infection.

Abstract
BACKGROUND Tenofovir disoproxil fumarate (TDF) is recommended for the prevention of perinatal transmission of the hepatitis B virus (HBV). This study aimed to systematically assess the efficacy and safety of TDF in pregnant women with chronic HBV and their infants. MATERIAL AND METHODS Database searches were performed to identify studies blocking the mother-to-child transmission of the hepatitis B virus with tenofovir. The search included pregnant women with chronic HBV infection administered with TDF compared to the no treatment controls, and data from individual studies were pooled using RevMan v5.3 for meta-analysis. RESULTS Seven studies with a total of 911 patients met the inclusion criteria: 433 patients in the TDF group and 478 patients in the non-TDF group. The HBV mother-to-child transmission rate in the tenofovir group was effectively reduced compared to the control group (RR: 0.18, 95% CI: 0.08-0.40). HBV-DNA positivity was also significantly low in infants from TDF group (RR: 0.17, 95% CI: 0.10-0.30) and the TDF treatment resulted in significantly higher anti-HBs production (RR: 1.11, 95% CI: 1.04-1.18). Similarly, maternal HBV-DNA was suppression was significantly high in the TDF group (RR: 34.16, 95% CI: 16.40-71.13). Women treated with TDF and their infants did not result in serious adverse events that are statistically different as compared to the women who did not receive any treatment. CONCLUSION Treatment of HBV infected pregnant women with TDF can effectively and safely prevent the perinatal transmission of chronic hepatitis B.

Abstract
BACKGROUND Several antiviral agents licenced for blocking mother-to-child transmission (MTCT) of HBV, but their relative efficacy beginning from different trimesters has scarce been evaluated. We aimed to conduct a network meta-analysis to statistically differ the efficacy and safety of each antiviral agents initiating on different timings in preventing mother-to-infant transmission of HBV. METHODS Studies were included from PubMed, EMBASE, Web of Science, and Cochrane databases through July 1, 2019. Eligible studies recruited randomized controlled trials and nonrandomized studies reporting about infant or/and maternal efficacy and safety outcomes and were screened by two investigators independently. Extracted data were analyzed by pair-wised and network meta-analysis, respectively. RESULTS 3 Randomized and 32 nonrandomized studies enrolling 6738 pregnant female were included. Using network analysis, any antiviral agent interrupted HBV vertical transmission much more effectively than placebo. No agent showed significant efficacy different from others, but a strong trend toward significance was found in telbivudine and tenofovir, of which had the highest probability of being ranked the first- or second-best treatment for reducing MTCT of HBV. The treatment applied in the first and second trimester had a similar efficacy in preventing MTCT. Compared with the initiation during the third trimester, lower rate of MTCT was revealed when antiviral therapy was administrated before third trimester, (RR = 0.045, 95% CI 0.0053 to 0.20); a similar effect at delivery on suppressing maternal HBV DNA level and converting serum HBeAg were achieved if the timing of antiviral treatment started prior, but an obvious improvement of normalizing ALT flare was calculated out; no statistically differences among maternal and fetal safety outcomes were found if mothers received antiviral agents before pregnant 28 weeks. CONCLUSION This network meta-analysis recommended the earlier use of telbivudine or tenofovir, tends to be better to prevent MTCT of HBV in pregnancy with no increased adverse maternal or fetal outcomes.

Abstract
For pregnant women with high viral load, antiviral therapy has been administered
in addition to active and passive immune prophylaxis as a crucial adjunctive
therapy to interrupt mother-to-child hepatitis B virus (HBV) transmission
(MTCT). However, the time of antiviral therapy onset remains controversial. A
systematic review and meta-analysis was conducted to compare the efficacy of
antiviral therapy during the second or the third trimester for prevention of HBV
vertical transmission. We searched nine databases for observational studies and
randomized controlled trials that enrolled pregnant women with positive HBsAg
treated with antivirals. The outcomes of interest were maternal HBV-DNA levels
prior to delivery and the rates of HBV MTCT. We included nine studies that
enrolled 1,502 pregnant women. The average HBV-DNA level before treatment was
approximately 8 log10 copies/mL. Compared to the onset of antiviral
intervention in the third trimester, the beginning of treatment in the second
trimester distinctly reduced maternal predelivery HBV-DNA levels. However, no
significant difference in HBV MTCT was found between the second and third
trimester groups. Furthermore, the subgroup analysis showed that there were no
significant differences between groups beginning treatment at different times
(second or third trimester) with regard to HBV MTCT or other evaluated
endpoints. For pregnant women with HBV-DNA levels less than or equal to 8
log10 copies/mL, the beginning of antiviral treatment can be
delayed until the third trimester.

Abstract
The hepatitis B virus (HBV) is an important human pathogen. Unvaccinated infants infected through mother-to-child transmission (MTCT) are at >95% risk of developing serum hepatitis B surface antigen-positive chronic hepatitis B (CHB). Despite complete passive-active HBV immunoprophylaxis, approximately 10% of infants born to mothers who are highly viremic develop CHB, and thus maternal treatment with nucleos(t)ide analogs (tenofovir disoproxil fumarate, lamivudine, or telbivudine) is recommended in the third trimester of pregnancy to reduce MTCT risk. Viral rebound usually occurs after stopping treatment and, in the context of maternal immunologic reconstitution postpartum, can also precipitate host immune-mediated hepatic (biochemical) flares. In this article, we review the epidemiology of HBV MTCT, discuss management and potential mechanisms of HBV vertical transmission, and highlight recent studies on virologic and immunologic aspects of hepatitis B in pregnancy and postpartum.

[PMID: 31807036 PMCID: PMC6844215 DOI: 10.2147/idr.s228982] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2019] [Accepted: 10/25/2019] [Indexed: 12/17/2022] Open
Abstract
Purpose To investigate whether tenofovir disoproxil fumarate (TDF) treatment that started from the second trimester had an advantage over TDF treatment that started from the third trimester. Patients and methods Twenty 35-year-old pregnant women with hepatitis B virus (HBV) DNA >2×106 IU/mL were prospectively enrolled in this study. All participants were divided into two subgroups: the second trimester group who started TDF treatment at 24-27 weeks and the third trimester group who started TDF treatment at 28-30 weeks. The primary outcome was the change in serum HBV DNA level from baseline to delivery. Each parameter was tested every 4 weeks from TDF initiation to 3 months postpartum. Results There were 80 pregnant women in the second trimester group and 49 pregnant women in the third trimester group. The decline in HBV DNA from baseline to delivery was more obvious in the second trimester group (4.8±1.2 log10 IU/mL) than that in the third trimester group (4.3±1.1 log10 IU/mL, p=0.041). The downward shift of haemoglobin (HB) from baseline to delivery was greater in the second trimester group (10.6±10.7 g/L) than in the third trimester group (6.3±12.3 g/L, p=0.041). The decline in HBV DNA from baseline to delivery was linearly related to the start of TDF treatment from the second trimester (β=0.50 and 95% CI: 0.26-0.75, p<0.001). There were no significant differences between the two groups regarding HBV serologic markers and safety indicators. Conclusion Starting TDF treatment from the second trimester achieved better viral suppression than starting TDF treatment from the third trimester in highly viraemic pregnant women without increasing additional adverse reactions. HB level needed frequent monitoring during treatment to avoid anaemia. Registry number Clinical Trial No. NCT02719808.

Comparing the Efficacy and Safety of Treating Chronic Hepatitis B Infection during Pregnancy with Lamivudine, Telbivudine, and Tenofovir: A Meta-analysis. J Clin Transl Hepatol 2019; 7:197-212. [PMID: 31608211 PMCID: PMC6783676 DOI: 10.14218/jcth.2019.00021] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2019] [Revised: 08/13/2019] [Accepted: 08/19/2019] [Indexed: 12/14/2022] Open
Abstract
Background and Aims: The perinatal transmission of hepatitis B virus (HBV) remains an important global health problem. Here, a systematic review and meta-analysis were conducted to evaluate the evidence regarding the efficacy and maternal/fetal safety of treating pregnant women with lamivudine, telbivudine (LdT), and tenofovir (TDF). Methods: A PubMed and Scopus search resulted in 1,076 records, which were reduced to 36, containing 7,717 pregnant women with chronic HBV infection and 7467 infants meeting the inclusion criteria. The latest search was in August 2019. Results: Treatment with LdT, but not lamivudine and TDF, could significantly reduce the hepatitis B virus surface antigen-positive rate (odds ratio (OR) = 0.37) in infants; it also led to higher rates of hepatitis B e antigen loss (OR = 12.14), hepatitis B e antigen seroconversion (OR = 8.93), and alanine aminotransferase normalization in mothers (OR = 1.49). Each of these treatments was able to significantly reduce HBV DNA positivity at birth (total OR = 0.19) and mother-to-child-transmission of HBV (total OR = 0.15), and to cause higher rates of HBV DNA suppression in mothers (total OR = 25.53). However, nucleos(t)ide analogues might also be involved in creatine kinase elevation (total OR = 7.48). In contrast, no significant association was found between nucleos(t)ide analogue therapy and preterm/premature births, congenital malformation, low birth weight, and abortion or fetal/infant death. The results suggested LdT's high capability of preventing mother-to-child-transmission. However, TDF failed to show significant associations to a reduced risk of mother-to-child-transmission, probably due to the low number of patients included. Conclusions: Although using either lamivudine, LdT, or TDF could lead to more favorable maternal/fetal outcomes, LdT seemed to show more potential in resolving certain infant- and maternal-related outcomes. More studies on the safety profile of such treatments are required.

Abstract
Liver diseases during pregnancy pose a unique clinical challenge because they can affect the lives of both the mother and unborn child. Although severe liver disease is rare, pregnancy-related liver disease affects approximately 3% of pregnancies and can be fatal. Timely recognition and diagnosis are essential in order to institute appropriate management strategies. This article provides an overview of liver diseases during pregnancy and is divided into 2 sections: (1) liver diseases specific to pregnancy, and (2) preexisting or coincident liver diseases during pregnancy.

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
INTRODUCTION HIV incidence among men who have sex with men (MSM) is high in China. Pre-exposure prophylaxis (PrEP) is a promising mean to prevent HIV transmission but it is not widely available in China. We conducted a large Internet-based online survey to assess the willingness of Chinese MSM to take PrEP and associated factors to their uptake preferences. METHODS Between 19 January and 6 February, 2017, 4581 MSM aged over 15 years were recruited via a social networking app to take an online PrEP survey. HIV status at the time of the survey being conducted was not one of recruitment criteria. Participants were asked if they had heard of PrEP, if they had concerns about PrEP, and if they would be ready to uptake PrEP should it be provided. When asked if participants were willing to take PrEP, they were asked to select from the following responses: "definitely not," "probably not," "not sure," "probably yes," and "definitely yes." In the final analysis, we grouped these five-level Likert scale responses into three-level responses as "definitely yes," "probably yes," and "no (definitely not/probably not/not sure)." Descriptive analysis and multinomial logistic regressions were conducted to assess the associations of PrEP adoption readiness and uptake concerns with HIV risk behaviours and demographic characteristics. RESULTS MSM from 33 geographical regions of China participated in the survey. The majority were younger than 25 (65.2%) and had attended college (68.6%). HIV prevalence was high (6.8%) and 43.3% reported a history of unprotected anal sex. Only 22.4% of participants had heard of PrEP. When asked if they would uptake PrEP, 26.0% said "definitely yes," 49.6% were "probably yes," and 24.4% said "no." PrEP adoption readiness was associated with having previously heard of PrEP and expressing concerns about accessibility and cost. Worries about side effects, low perceived HIV risk, preference for condoms, and never having received HIV testing were negatively associated with PrEP uptake willingness. CONCLUSION Young and well-educated Chinese MSM reported a low willingness to uptake PrEP despite being high-risk for HIV. Effective education, especially through online mediums, will be critical to optimize this group's PrEP uptake.

Abstract
Hepatitis B virus (HBV) infection is an important public health problem in Canada. In keeping with evolving evidence and understanding of HBV pathogenesis, the Canadian Association for the Study of Liver Disease periodically publishes HBV management guidelines. The goals of the 2018 guidelines are to (1) highlight the public health impact of HBV infection in Canada and the need to improve diagnosis and linkage to care, (2) recommend current best-practice guidelines for treatment of HBV, (3) summarize the key HBV laboratory diagnostic tests, and (4) review evidence on HBV management in special patient populations and include more detail on management of HBV in pediatric populations. An overview of novel HBV tests and therapies for HBV in development is provided to highlight the recent advances in HBV clinical research. The aim and scope of these guidelines are to serve as an up-to-date, comprehensive resource for Canadian health care providers in the management of HBV infection.

Abstract
BACKGROUND AND GOALS A series of changes in the immune system occur during pregnancy and puerperium. Currently, we aim to characterize both the natural changes in liver inflammation and its association with hepatitis B viremia during this special period. PATIENTS AND METHODS Chronic hepatitis B (CHB) gravidas were recruited and followed up to 52 weeks postpartum. Virological and biochemical parameters were assessed throughout the period. RESULTS A total of 1097 CHB mothers had finished the entire follow-up including 451 accepting telbivudine, 178 accepting tenofovir, and 468 without antiviral therapy. Among the mothers, 11.94% went through hepatic flare in the first trimester and the rate decreased to 2.1% at the time of delivery. Nevertheless, a much higher frequency (19.78%) was observed in the early postpartum. Interestingly, alanine aminotransferase level decreased along with the development of pregnancy and then suddenly increased in the first month of puerperium. In addition, a downward trend was observed on the titer of HBsAg and HBeAg after delivery. Of note, an obvious higher frequency of alanine aminotransferase flare was revealed in mothers with high viremia (>6 log10 IU/mL). With multivariate analysis, only hepatitis B virus titer at baseline was strongly associated with hepatic flare during early postpartum (95% confidence interval, 1.012-3.049, P=0.045). The predictive rates of hepatic flare at baseline viral load of 6, 7, and 8 log10 IU/mL were 16.67%, 28.30%, and 30.60%, respectively. CONCLUSIONS CHB gravidas with high viremia should be monitored closely during entire pregnancy, and extended antiviral therapy is recommend to those mothers with baseline viremia >7 log10 IU/mL.

Abstract
Mother-to-child transmission is the major cause of chronic hepatitis B virus (HBV) infection. This double-blind trial tested the effect of tenofovir disoproxil fumarate (TDF) in preventing vertical transmission. Pregnant women who were HBsAg/HBeAg-positive with a HBV DNA titer ≥ 2×106 IU/mL were randomly assigned to the control (n = 60) and TDF-treated (n = 60) groups. TDF treatment (oral dose 300 mg/day) was initiated at 24 weeks of gestation and continued to 4 weeks after delivery. The subjects were followed up to 28 weeks postpartum. The effects of TDF on vertical transmission, outcomes of the mothers and infants and virological changes were monitored. TDF dynamically reduced the serum HBV DNA level of the mothers, particularly during the first 4 weeks of treatment. The lower viral loads were maintained in the pregnancies until delivery. Approximately 90% and 33.9% of the TDF-treated mothers had viral loads ≤2000 IU/mL after delivery and at 28 weeks postpartum, respectively. No cervical transmission or adverse effects were observed in the TDF-treated individuals, whereas 13.5% of the infants were infected with HBV in the control group. We conclude that TDF treatment initiated at 24 weeks of gestation in high-viremia, HBsAg/HBeAg-positive mothers efficiently prevents mother-to-child HBV transmission without adverse events in mothers and infants.

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.

Li W, Jia L, Zhao X, Wu X, Tang H. Efficacy and safety of tenofovir in preventing mother-to-infant transmission of hepatitis B virus: a meta-analysis based on 6 studies from China and 3 studies from other countries. BMC Gastroenterol 2018; 18:121. [PMID: 30071845 PMCID: PMC6090972 DOI: 10.1186/s12876-018-0847-2] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2018] [Accepted: 07/16/2018] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND The vertical transmission of HBV from mothers to their infants at birth or in early infancy has a significant role in the endemicity of HBV infection. Tenofovir is one of the most potent anti-HBV agents with a high genetic barrier to resistance. The study is to evaluate the efficacy of tenofovir in preventing perinatal HBV transmission, as well as monitoring safety for mothers and infants. METHODS PubMed, Embase, Web of Science, and CNKI (National Knowledge Infrastructure, China) database were systematically reviewed for studies that compared the efficacy and safety of tenofovir with other treatments. Pooled estimates were expressed with weight mean difference (WMD) with 95% confidence intervals (95% CIs) and risk ratio (RR) with 95% CIs. RESULTS Nine studies involving 1046 pregnant patients met the inclusion criteria and were included in this meta-analysis. Compared with other treatments, tenofovir significantly reduced maternal HBV DNA levels (WMD = 2.33 log10 IU/mL, 95% CI: 1.01, 3.64; P < 0.001), infant HBsAg positivity rate (RR = 0.25, 95% CI: 0.16, 0.38; P < 0.001), infant HBeAg positivity rate (RR = 0.26, 95% CI: 0.14, 0.48; P < 0.001), infant HBV DNA positivity rate (RR = 0.15, 95% CI: 0.07, 0.31; P < 0.001), and immunoprophylaxis failure rate (RR = 0.31, 95% CI: 0.13, 0.73; P = 0.008). Moreover, maternal and infant safety profiles, including ALT, CK, and Cr were comparable between tenofovir and other treatment groups. CONCLUSION Based on the current evidence, our study suggested that tenofovir significantly reduced the rate of vertical transmission of HBV, as well as the HBV DNA levels in HBV-infected mothers. Moreover, tenofovir was safe and tolerable for both mothers and their infants.

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 (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
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.

Antiretroviral therapy for pregnant women living with HIV or hepatitis B: a systematic review and meta-analysis. BMJ Open 2017; 7:e019022.

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
This study was a meta-analysis of the literature on the efficacy and safety of tenofovir disoproxil fumarate (TDF) in preventing vertical transmission of hepatitis B in pregnancies with high viral load. Four observational studies and one randomized controlled trial involving 585 pregnant women and 595 newborns were included in the meta-analysis. TDF was more effective than the placebo in reducing vertical transmission in HBeAg-positive chronic hepatitis B (CHB) pregnancies with high serum HBV-DNA levels (OR = 0.21, 95% CI = 0.07–0.61) at 4–12 months, infant HBV DNA seropositivity at delivery (OR = 0.16, 95% CI = 0.07–0.37), and a severe flair in maternal alanine aminotransferase (ALT) levels (OR = 0.43, 95% CI = 0.19–0.95) during pregnancy. In addition, TDF showed more improvement in HBV DNA suppression at delivery (OR = 254.46, 95% CI = 28.39–2280.79). No significant differences were found in HBeAg seroconversion or ALT normalization; or in rates of cesarean section, emergent cesarean section, postpartum hemorrhage, prematurity, congenital malformations, or infant death. However, TDF induced more drug-related adverse events (OR = 2.33, 95% CI = 1.39–3.89) and elevated creatine kinase (CK) (OR = 9.56, 95% CI = 1.17–78.09) than in controls. The available evidence suggests that TDF is effective and safe in preventing vertical transmission of hepatitis B in pregnancies exhibiting a high viral load.

Abstract
INTRODUCTION In settings where HIV is prevalent in heterosexual populations, pregnancy and postpartum breastfeeding periods can be associated with substantial HIV acquisition risk. Pre-exposure prophylaxis (PrEP) with daily oral tenofovir disoproxil fumarate (TDF)/emtricitabine is an attractive HIV prevention option for women who are lactating but data are limited on its safety during the lactation period. Areas covered: We provide a concise synthesis and summary of current evidence on the safety of TDF-based PrEP during breastfeeding. We conducted a review, searching Pubmed database and major PrEP conferences for primary studies with TDF-based PrEP exposure during postpartum breastfeeding. Expert opinion: TDF-based oral PrEP is an effective female-controlled HIV prevention option. There is evidence supporting the safety of TDF use for infant outcomes during breastfeeding in antiretroviral treatment regimens for HIV and hepatitis B virus, and more limited, but consistently safe, data from use of TDF as PrEP. The potential for risk is arguably outweighed for at-risk individuals by HIV prevention benefits, including indirect protection to the infant as a result of preventing HIV in the breastfeeding mother. As PrEP delivery is scaled up in heterosexual populations in high HIV prevalence settings and for at-risk persons in other settings, implementation science studies can provide a framework to increase the accrual of safety, acceptability, and use data related to PrEP during lactation.

Abstract
BACKGROUND Despite universal vaccination, chronic hepatitis B virus (HBV) infection remains a public health concern in North America owing to immigration. We aimed to characterize the number of people with a positive result of testing for HBV surface antigen (HBsAg) in Calgary, a large urban Canadian health care region, and to assess whether recommended laboratory tests and specialist consultation were done for those identified as HBsAg-positive. METHODS Based on laboratory and Alberta Health Services administrative data, we identified all adults (age > 18 yr) with a positive HBsAg test result from Jan. 1 to Dec. 31, 2014 within the Calgary Zone. Demographic and relevant laboratory data were extracted within 6 months of a positive HBsAg test result, and referral to hepatology (2011-2014) was identified from data on referral to a centralized clinic. Parametric and nonparametric statistical methods were used for analyses. RESULTS We identified 1214 HBsAg-positive people (584 women [48.1%]; median age 44 [interquartile range (IQR) 36-55] yr). A total of 1192 people (98.2%) had alanine aminotransferase testing (median level 23 [IQR 16-34] U/L; 117 [9.8%] with elevated levels), 682 (56.2%) had testing for HBV DNA (median level 2.8 [IQR 2.1-3.8] logIU/mL), 630 (51.9%) had HBV e antigen testing (negative result in 548 [87.0%]), and 145 (11.9%) had HBV e antibody testing (positive result in 111 [76.6%]). Overall, 144 people (11.9%) received anti-HBV treatment, and 390 (32.1%) were referred to a hepatologist. INTERPRETATION Many HBsAg-positive people in Calgary did not receive the recommended laboratory assessments. The results highlight the necessity of continual public health efforts to screen for chronic HBV infection in Canada and to ensure adequate follow-up in order to reach the World Health Organization's goal of viral hepatitis elimination by 2030.

[PMID: 28436552 DOI: 10.1111/apt.14068] [Citation(s) in RCA: 54] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2016] [Revised: 11/27/2016] [Accepted: 03/09/2017] [Indexed: 12/12/2022]
Abstract
BACKGROUND Preventing mother to child transmission of chronic hepatitis B infection in the setting of a high maternal viral load is challenging. The idea has emerged from antepartum tenofovir treatment with combination immunoprophylaxis. AIMS To demonstrate the efficacy and safety of tenofovir to prevent mother to child transmission of hepatitis B virus. METHODS PubMed, EMBASE, and Cochrane databases were searched through August 16, 2016. Comparative trials of second or third trimester tenofovir administration vs. controls for patients with chronic hepatitis B infection and non-comparative case series assessing mother to child transmission rates and evaluating maternal and foetal safety outcomes were included. RESULTS Ten studies (one randomised controlled trial, four non-randomised controlled trials and five case series) that enrolled 733 women were included. The pooled results from comparative trials (599 pregnancies) showed that tenofovir significantly reduced the risk of infant hepatitis B surface antigen seropositivity by 77% (odds ratio=0.23, 95% confidence intervals=0.10-0.52, P=.0004) without heterogeneity (I2 =0%). In the case series analysis (134 pregnancies), only two cases (1.5%) of mother to child transmission with extremely high maternal viral load and non-compliance to treatment were identified. Maternal and foetal safety parameters including congenital malformation and foetal death were re-assuring. CONCLUSIONS For pregnant women with high hepatitis B virus DNA levels, tenofovir administration in the second or third trimester can prevent mother to child transmission when combined with hepatitis B immunoglobulin and the hepatitis B vaccine. Tenofovir is safe and tolerable for both the mother and foetus.

Peripartum cytokine flares in a multiethnic cohort of chronic hepatitis B carriers does not correlate with hepatitis B virus suppression or increased risk of liver disease.

Abstract
PROBLEM In chronic hepatitis B (CHB) carriers, alanine transaminase (ALT) flares are common in the peripartum period. There are limited data on immunological changes of pregnancy in CHB. We hypothesize that in pregnant CHB carriers, the Th1/Th2 cytokine ratio is altered resulting in changes in biochemical/virological and liver fibrosis markers. STUDY METHODS Serum from 38 pregnant/post-partum CHB carriers (median age 32 years, 53% Asian, 8 HBeAg+ ) was tested for HBV DNA, quantitative HBV surface antigen, ALT and liver fibrosis by transient elastography (TE). Serum cytokines were analyzed using a Luminex assay. RESULTS Untreated CHB cases had mild ALT flares post-partum, but showed normal TE, and no change in viral markers despite increased Th1 cytokines compared to healthy controls (P<.05). CONCLUSION CHB carriers show increased Th1 cytokines in the peripartum period albeit with no effect on viral load or liver disease suggesting an aborted antiviral immune response.

Abstract
BACKGROUND The risk of vertical transmission of hepatitis B virus (HBV) increases as maternal HBV DNA increase, despite serovaccination to newborns. METHODS From 1 July 2012 to 1 January 2016, all pregnant women in Lariboisiere Hospital, Paris, France, with HBV DNA of 5 log10 IU/ml and above were administered tenofovir from week 28 of pregnancy until delivery. HBV DNA was measured at months 1, 2 of tenofovir and at delivery. The newborns were serovaccinated, tested for hepatitis B surface antigen, hepatitis B core antibody (HBcAb)±HBV DNA, and hepatitis B surface antibody (HBsAb) when aged 9 months, and then 24 months. This study was registered in http://www.ClinicalTrials.gov (NCT02039362). RESULTS Thirty-one women gave birth to 37 newborns. Maternal HBV DNA at baseline was 8.23 log10 IU/ml and above in 12 pregnancies. The mean (median) HBV DNA were 4.4±1.2 (4.8), 3.3±1.7 (3.8), and 2.1±1.9 (2.0) log10 IU/ml at months 1, 2 of tenofovir and at delivery, respectively. Twenty-seven newborns were followed up: none of the 19 children aged 9 months or older was positive for hepatitis B surface antigen when aged 9 months; 14 children tested positive for HBcAb (probably transferred maternal antibodies, not found when aged 24 months) and for HBsAb without HBV DNA. Four of the 19 children showed HBsAb without HBcAb, the last being doubtful for HBcAb and HBsAb without HBV DNA. Eight newborns aged less than 9 months were not tested. CONCLUSION Tenofovir from week 28 of pregnancy to highly viremic HBV women plus serovaccination to newborns could prevent chronic and past infection.

Abstract
OBJECTIVES Pregnant/lactating women in some sub-Saharan Africa settings are at substantial risk of HIV acquisition and could benefit from preexposure prophylaxis (PrEP) with tenofovir disoproxil fumarate (TDF), but safety data in pregnancy/lactation are limited. DESIGN Systematic data review through August 2016. METHODS We reviewed research reports/conference abstracts with maternal/child adverse outcome data in HIV-infected and HIV-uninfected pregnant/lactating women receiving TDF alone or in combination with other drugs compared with non-TDF regimens. RESULTS In total, 26 articles in HIV-infected and seven in HIV-uninfected women were identified. No statistically significant differences were observed between TDF and comparison non-TDF regimens in pregnancy incidence, stillbirth/pregnancy loss, preterm delivery less than 37 weeks, low birth weight <2500/<1500 g, small for gestational age, birth defects, or infant (>14 days) or maternal mortality. One study reported significantly higher very preterm delivery (<34 weeks) and neonatal mortality with TDF versus non-TDF antiretroviral therapy (ART), but no significant difference between TDF ART and zidovudine/single-dose nevirapine. Most studies report normal infant linear growth; one study showed slightly lower, and one higher 1-year length-for-age z-score in TDF ART-exposed infants. No significant differences were reported in abnormal laboratory values or bone markers between TDF and non-TDF-exposed infants in four studies. Lower maternal bone mineral density was observed at 74 weeks postpartum in breastfeeding women on TDF ART compared with no ART in one study. CONCLUSION Given available safety data, there does not appear to be a safety-related rationale for prohibiting PrEP during pregnancy/lactation or for discontinuing PrEP in HIV-uninfected women receiving PrEP who become pregnant and are at continuing risk of HIV acquisition.

Abstract
BACKGROUND & AIMS Vertical transmission of hepatitis B virus (HBV) can occur despite immunoprophylaxis in mothers with high HBV DNA levels (>5-7 log10 IU/ml). Quantitative hepatitis B surface antigen (qHBsAg) testing could be used as a surrogate marker to identify high viral load carriers, but there is limited data in pregnancy. We conducted a prospective observational study to determine the cost-effectiveness and utility of qHBsAg as a valid surrogate marker of HBV DNA. METHODS Pregnant patients with chronic hepatitis B were recruited from a tertiary referral centre. HBV DNA levels and qHBsAg were assessed in the second to third trimester. Statistical analysis was performed by Spearman's rank correlation and student's t-test. The cost-effectiveness of qHBsAg as compared to HBV DNA testing was calculated. RESULTS Ninety nine women with 103 pregnancies, median age 32 years, 65% Asian, 23% African and 12% other [Hispanic, Caucasian] were enrolled. Overall, 23% (23/99) were HBV e Ag (HBeAg)-positive. A significant correlation between qHBsAg and HBV DNA levels was noted in HBeAg-positive patients (r = 0.79, P < 0.05) but not in HBeAg-negative patients (r = 0.17, P = 0.06). In receiver operating characteristic analysis, the optimal qHBsAg cut-off values for predicting maternal viraemia associated with immunoprophylaxis failure (i.e., HBV DNA ≥7 log10 IU/ml) was 4.3 log10 IU/ml (accuracy 98.7%, sensitivity 94.7%, specificity 94.4%) (95% CI, 97-100%, P < 0.05). Use of HBV DNA as compared to qHBsAg costs approximately $20 000 more per infection prevented. CONCLUSION In resource poor regions, qHBsAg could be used as a more cost-effective marker for high maternal viraemia, and indicate when anti-HBV nucleos/tide analogue therapy should be used to prevent HBV immunoprophylaxis failure.

Serum Alanine Aminotransferase and Hepatitis B DNA Flares in Pregnant and Postpartum Women with Chronic Hepatitis B. Am J Gastroenterol 2016; 111:1410-1415. [PMID: 27456990 DOI: 10.1038/ajg.2016.296] [Citation(s) in RCA: 51] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/01/2016] [Accepted: 06/09/2016] [Indexed: 12/11/2022]
Abstract
OBJECTIVES Alterations in the immune system during pregnancy have been associated with reactivation of hepatitis B virus (HBV) in chronic hepatitis B (CHB) women. However, the effects of pregnancy on CHB remain not well understood. The goal of this study was to examine flares in HBV DNA and serum alanine aminotransferase (ALT) during pregnancy and postpartum in CHB women untreated prior to pregnancy. METHODS This was a multicenter retrospective study of 113 pregnancies in 101 CHB women who presented during pregnancy at two community gastroenterology clinics and two tertiary medical centers in the United States during 1997-2015. Outcomes analyzed included onset, severity, and resolution of flares in HBV and ALT that occurred prior to starting antiviral therapy, if antiviral therapy was subsequently initiated. Women who initiated antiviral therapy during pregnancy were not included in the analysis of postpartum flares. RESULTS HBV DNA flares were observed in 9% (8/90) of women during pregnancy and 4% (2/48) of women during postpartum. Flares in ALT (99-2522 U/l) were observed in 6% (7/112) of women during pregnancy and 10% (5/51) of women within the first 3 months of delivery. Age, HBeAg positivity, baseline HBV DNA, baseline ALT, gravida, and parity were not found to be significant predictors of flare. CONCLUSIONS Flares in HBV DNA and ALT can occur during late pregnancy and early postpartum in CHB women, and can be severe. Women with CHB should therefore be closely monitored during pregnancy and early postpartum.

Abstract
BACKGROUND There is limited information on antiviral therapy for hepatitis B virus (HBV) infection among pregnant women coinfected with human immunodeficiency virus (HIV) and HBV. METHODS A phase 2 randomized, controlled trial of a regimen containing tenofovir (TDF)/lamivudine (3TC) and a regimen containing 3TC in HIV/HBV-coinfected pregnant women in China. The HBV virological response was compared in study arms. RESULTS The median decline in the HBV DNA level was 2.60 log10 copies/mL in the TDF/3TC arm and 2.24 log10 copies/mL in the 3TC arm (P = .41). All women achieved HBV DNA levels of <6 log10 copies/mL at delivery. CONCLUSIONS Initiation of either regimen led to achievement of HBV DNA levels below the threshold associated with perinatal HBV transmission. CLINICAL TRIALS REGISTRATION NCT01125696.
