Abstract
Pregnant women with chronic hepatitis B (CHB) are a priority population for hepatitis B care. Identification of HBV status prior to pregnancy would facilitate timely maternal interventions and perinatal care. In our study, we aimed to study the epidemiology of CHB among women of childbearing age (WoCBA, 18-49 years) in Alberta, Canada. We retrospectively analysed Alberta Analytics databases to study CHB epidemiology, natural history and care linkage among WoCBA in Alberta, between April 2012 and March 2021. A Poisson regression was conducted to estimate incidence of newly identified CHB cases and prevalence trends, whereas predictors of care linkage were determined using logistic regression. Age/sex-adjusted incidence of newly identified CHB among WoCBA between 2015 and 2020 was 36.2/100,000 person/years, highest among individuals aged 30-39 years. Incidence of newly identified CHB decreased from 52.6 to 18.2/100,000 between 2015 and 2020, but prevalence increased from 131.7 to 248.6/100,000 in the same period. Newly identified CHB incident cases (n = 2124) had lower survival rates than age/sex-matched Canadians, with a standardized mortality ratio of 5.7 (95% CI 2.6-11.0). Increasing age (years) at diagnosis (HR, 1.2; 95% CI 1.1-1.3) was independently associated with mortality. Comorbid hepatocellular carcinoma, anti-HBV treatment and year of diagnosis were not significantly associated with mortality. Of the 1927 women with 2436 hepatitis B surface antigen-positive pregnancies from 2012 to 2020, only 27.6% had recommended HBV assessment during pregnancy. Of those women meeting criteria for antiviral therapy to prevent mother-to-child transmission (MTCT), only 66.4% received treatment. Suboptimal management during pregnancy and overall lower survival rates highlight the need to address care linkage barriers in women of childbearing age living with CHB.

A pilot integrated model nurse clinic increases the uptake of antiviral treatment for the prevention of mother-to-child transmission of HBV. Liver Int 2024. [PMID: 38967425 DOI: 10.1111/liv.16028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Revised: 04/18/2024] [Accepted: 06/25/2024] [Indexed: 07/06/2024]
Abstract
BACKGROUND AND AIMS Mother-to-child-transmission (MTCT) of hepatitis B virus (HBV) may still occur despite birth-dose HBV vaccinations when pregnant women are positive for hepatitis B surface antigen (HBsAg) with high viral loads (HBV DNA ≥ 200 000 IU/mL). A pilot integrated model nurse clinic (IMNC) was started in 2020 to implement the pre-emptive antiviral therapy with tenofovir disoproxil fumarate (TDF). We aimed to evaluate the performance of IMNC on uptake of TDF. METHODS This was a territory-wide retrospective cohort of all consecutive HBsAg-positive women of child-bearing age with pregnancy records in public hospitals 2019-2022. Demographic characteristics, liver biochemistries and virologic parameters, and TDF use were collected. Concurrently, data from a prospective audit in Union Hospital, the private hospital with the highest number of deliveries in Hong Kong, from June 2022 to May 2023 were compared. RESULTS The prevalence rate of HBV DNA ≥ 200 000 IU/mL in pregnant women with available HBV DNA records was 29.2% (66/226) in 2019, 27.3% (99/363) in 2020, 15.9% (125/784) in 2021 and 17.2% (117/679) in 2022 (p < .001), out of 2052 pregnant women who had their HBV DNA checked within 1 year prior to delivery. An increasing uptake rate of TDF by highly viraemic pregnant women (i.e. ≥ 200 000 IU/mL) was noted after the commencement of IMNC in public hospitals, with 67% (45/67) in 2019, 83% (88/106) in 2020, 91% (117/128) in 2021 and 89% (149/167) in 2022. Moreover, all highly viraemic pregnant women from Union Hospital received TDF. Continuous use of TDF was associated with a reduced risk of postpartum biochemical flare. CONCLUSIONS IMNC increases the uptake of antiviral treatment in pregnant women at risk of MTCT of HBV. IMNC contributes to hepatitis elimination through a structured care plan to prevent MTCT of HBV.

Abstract
AIMS The World Health Organization (WHO) estimates that 3.5% of the population live with hepatitis B virus (HBV); migrants to Europe are disproportionately affected. UK birth dose HBV vaccination is limited to infants born to those living with HBV (LWHBV). High-risk infants (high maternal infectivity, low birthweight) also receive HBV immunoglobulin (HBIG). The Family Hepatitis Clinic follows infants and those LWHBV working towards WHO goals of combating viral hepatitis by 2030. METHODS A trust-wide electronic note review of outcomes for infants born to those LWHBV (2016-2020). RESULTS Two hundred and eighty-three infants, 134 (47%) females, born to those LWHBV were referred. Two hundred and thirty-one (82%) attended follow-up with a vertical transmission rate of 0%. Twenty (7%) individuals LWHBV received tenofovir disoproxil fumerate in pregnancy; median viral load (VL) at initiation 125 416 376 DNA IU/mL, one having birth VL. Twenty-eight (10%) infants were stratified as high risk and all received HBIG and birth dose vaccination with 9 (32%) subsequently lost to follow-up, compared to 48 (19%) low-risk infants. 267/283 (94%) had birth dose vaccination documented and 206/283 (73%) received at least four vaccine doses. 215/283 (76%) infants had serology by 24 months; 17 (6%) with suboptimal vaccine responses: hepatitis B surface antibody <100 IU/mL. Serology before 18 months resulted in higher rates of maternal hepatitis B core antibody detection (15% vs. 3%). CONCLUSION Prevention of vertical transmission of HBV was universal in those attending, although high-risk infants were more likely lost to follow up. HBV post-vaccine serological protection was comparable with national data from 2021 (77% >4 doses, 77% HBsAb >100).

Estimating the key outcomes and hepatocellular carcinoma risk in patients in immune-tolerant phase of chronic hepatitis B virus infection: A systematic review and meta-analysis. Rev Med Virol 2024; 34:e2570. [PMID: 38964866 DOI: 10.1002/rmv.2570] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2024] [Revised: 06/10/2024] [Accepted: 06/26/2024] [Indexed: 07/06/2024]
Abstract
The question of whether patients in the immune-tolerant (IT) phase of chronic hepatitis B virus (HBV) infection should undergo antiviral therapy and determine the optimal regimen remains unclear. A comprehensive search of PubMed, Embase, MEDLINE, Cochrane Library, and Wanfang Data from inception to 5 December 2023, was conducted. Studies reporting on key outcomes such as HBV DNA undetectability, HBeAg loss or seroconversion, HBsAg loss or seroconversion, and hepatocellular carcinoma (HCC) incidence in patients in the IT phase of chronic HBV infection were included. In total, 23 studies were incorporated. Approximately 4% of patients in the IT phase achieved spontaneous HBeAg loss over 48 weeks of follow-up. Antiviral therapy demonstrated a favourable impact on HBV DNA negative conversion (Children: risk ratios [RR] = 6.83, 95% CI: 2.90-16.05; Adults: RR = 25.84, 95% CI: 6.47-103.31) and HBsAg loss rates (Children: RR = 9.49, 95% CI: 1.74-51.76; Adults: RR = 7.35, 95% CI: 1.41-38.27) for patients in the IT phase. Subgroup analysis revealed that in adult patients in the IT phase, interferon plus nucleos(t)ide analogues (NA)-treated patients exhibited a higher pooled rate of HBsAg loss or seroconversion than those treated with NA monotherapy (9% vs. 0%). Additionally, the pooled annual HCC incidence for patients in the IT phase was 3.03 cases per 1000 person-years (95% CI: 0.99-5.88). Adult patients in the IT phase had a significantly lower HCC incidence risk than HBeAg-positive indeterminate phase patients (RR = 0.46, 95% CI: 0.32-0.66), with no significant differences observed between IT and immune-active phases. Presently, there is insufficient evidence solely based on reducing the risk of HCC incidence, to recommend treating patients in the IT phase of chronic HBV infection. However, both adult and paediatric patients in the IT phase responded well to antiviral therapy, showing favourable rates of HBsAg loss or seroconversion.

Abstract
Viral hepatitis during pregnancy is common globally. In this review, we focus on the antenatal screen for hepatitis A, B, C and E, the prevention of mother-to-child transmission (MTCT) of hepatitis B and C, and the management of hepatitis A, B, C and E during pregnancy. Neonatal timely administration of hepatitis B immunoglobulin and hepatitis B vaccine is the cornerstone for preventing MTCT of hepatitis B virus (HBV), and perinatal antiviral prophylaxis with tenofovir disoproxil fumarate in mothers with positive HBeAg or HBV DNA >2 × 105 IU/ml also plays important roles in further reducing MTCT. Avoidance of risk practices in managing labor and delivery process of women with HCV infection may be useful to reduce MTCT of HCV. Early recognition of severe hepatic injury or liver failure associated with hepatitis viruses by regular liver function tests is critical to prevent maternal mortality associated with hepatitis.

Abstract
Chronic hepatitis B (CHB) was, and still is, a prevalent liver disease in the world, especially high in the Asia-Pacific areas. With the advent of preventive vaccines and effective viral suppression drugs and active implementations, CHB has gradually become under control. The world-wide prevalence reduces from 4.2% in 1980 to 3.2% in 2020 study. CHB patients receiving long-term antiviral therapies significantly improve the clinical outcomes, saving from end-stage liver diseases. Despite of these impressive progresses, to meet the WHO sustained development goals (SDG) for CHB control, a 90% reduction of incidence and a 65% reduction of mortality in year 2030, there is still a long way to go. In this review, four ongoing approaches have been proposed: (i) A continuous monitoring of long-term vaccine efficacy in vaccinated populations; (ii) consolidating the hepatitis B virus vaccination program against vaccine hesitancy and limited resources; (iii) rolling-out current oral antivirals to more CHB patients not only for diseases treatment but also for infection preventions; and (iv) development of curative therapies, both friendly-to-dispense and affordable. A coherent and persevere efforts by the society may succeed and achieve the SDG for CHB in the future.

Tenofovir alafenamide or tenofovir disoproxil fumarate in pregnancy to prevent HBV transmission: Maternal ALT trajectory and infant outcomes. Liver Int 2024; 44:1422-1434.

Abstract
BACKGROUND The use of antiviral agents, specifically tenofovir disoproxil fumarate (TDF), in pregnant women to prevent mother-to-child HBV transmission is a key step towards hepatitis elimination. However, data on using tenofovir alafenamide (TAF) is insufficient. The frequent occurrence of postpartum ALT flares may impact the clinical implementation. METHODS The maternal and infant outcomes were compared in multi-centre trials of high viral load HBsAg/HBeAg+ pregnant women receiving TAF or TDF from the third trimester until 2 weeks postpartum with intensive follow-ups. To explore the dynamic pre- and postpartum changes in ALT levels, we used a group-based trajectory model for analysing data of 332 women from three prospective studies. RESULTS After treatment, the maternal HBV DNA levels significantly decreased from baseline to delivery: 7.87 ± 0.59 to 3.99 ± 1.07 Log10 IU/mL TAF (n = 78) and 8.30 ± 0.36 to 4.47 ± 0.86 Log10 IU/mL (TDF, n = 53), with viral load reductions of 3.87 versus 3.83 Log10 IU/mL. The HBsAg-positive rates among 12-month-old infants were 1.28% (1/78) versus 1.82% (1/55) respectively (p = 1.00). Of the TAF or TDF-treated mothers, 25.64% versus 16.98% experienced ALT > 2X ULN, and 11.54% versus 1.89% received extended antiviral treatment. Our model revealed four distinct ALT patterns: stable ALT (87.2%), moderate (8.0%) or marked (2.4%) postpartum flares, or prepartum elevations (2.4%). CONCLUSIONS TAF effectively reduces mother-to-child HBV transmission, but prophylaxis failure still occurred in few cases. Postpartum ALT flares are common in women receiving TAF or TDF during pregnancy. Approximately 12.8% of mothers may require extended postpartum antiviral treatment. CLINICAL TRIAL NUMBER NCT03695029 (ClinicalTrials.gov).

Abstract
OBJECTIVE Infection with the hepatitis delta virus (HDV), a unique RNA virus that requires hepatitis B virus (HBV) antigens for its assembly, replication, and transmission, causes severe viral hepatitis. Compared to HBV monoinfection, HDV infection increases the risk of severe liver disease, necessity for liver transplant, and mortality. Global HDV prevalence estimates vary from 5% to 15% among persons with HBV, but screening guidelines for HDV are inconsistent; some recommend risk-based screening, while others recommend universal screening for all people with HBV. Among primary care providers (PCPs) in the US, there is a lack of awareness and/or insufficient adherence to current recommendations for the screening of HDV infection and management of chronic HDV. METHODS Publications were obtained by conducting literature searches between July and August 2022 using the PubMed database and by manual searches of the retrieved literature for additional references. Information was synthesized to highlight HDV screening and management strategies for PCPs. Best practices for PCPs based on current guidelines and comanagement strategies for patients with HBV and HDV infection were summarized. RESULTS We recommend universal screening for HDV in patients positive for hepatitis B surface antigen. Confirmed HDV infection should prompt evaluation by a liver specialist, if available, with whom the PCP can comanage the patient. PCPs should counsel patients on the expected course of the disease, lifestyle factors that may influence liver health, need for consistent disease monitoring and follow-up, and risk of disease transmission. Screening is suggested for sexual partners, household contacts, and family members, with HBV immunization recommended for those found to be susceptible. There are currently no US Food and Drug Administration-approved therapies for HDV infection; thus, management is limited to treatments for chronic HBV infection plus long-term monitoring of liver health. CONCLUSIONS PCPs can be a valuable point of care for patients to access HDV/HBV screening, HBV immunization, and education, and can comanage patients with HBV and/or HDV infection.

Efficacy of antiviral therapy for the prevention of mother-to-child transmission of hepatitis B virus and the risk of postpartum hepatitis flare after discontinuation of antiviral therapy. Hepatol Res 2024. [PMID: 38651670 DOI: 10.1111/hepr.14048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Revised: 03/22/2024] [Accepted: 04/04/2024] [Indexed: 04/25/2024]
Abstract
The use of nucleos(t)ide analogs (NAs) is recommended for mothers with a high viral load of hepatitis B virus (HBV) during the second or third trimester of pregnancy. However, postpartum hepatitis flares can occur in some cases. We examined the efficacy of NA administration for the prevention of mother-to-child transmission of hepatitis B virus, and evaluated the risk of postpartum hepatitis flares in mothers after NA discontinuation. Nine pregnant women with a high viral load (HBV DNA ≥5.3 log IU/mL) received tenofovir disoproxil fumarate (TDF) at approximately 28 weeks of gestation, and TDF was discontinued at 4-10 weeks after delivery. We evaluated the virological and biochemical parameters in mothers after TDF discontinuation. Hepatitis flares in mothers were defined as alanine transaminase level ≥60 U/L. None of the infants developed any congenital anomaly or acquired HBV infection during infancy. Hepatitis flares occurred within 6 months after TDF discontinuation in five of seven cases, whereas two cases were lost to follow-up. Furthermore, three cases required the resumption of NA use. NA administration was highly effective against mother-to-child-transmission of HBV in pregnant women with high HBV DNA levels. However, hepatitis flares were commonly observed after NA discontinuation in the postpartum period. Patients should be followed up carefully after NA discontinuation, and NA resumption should be considered based on a comprehensive assessment of virological and biochemical parameters.

Abstract
Hepatitis B virus (HBV) infection was highly endemic in China, where the prevalence of HBsAg was 9.7% in 1992. Comprehensive strategies, including universal infant hepatitis B vaccination with emphasis on timely birth-dose and 3-dose coverage, dramatically reduced the mother-to-infant transmission and early childhood acquisition of HBV, resulting in estimated HBsAg prevalence rates of 5.6% and 0.1% in the general population and among children aged <5 years in 2022, respectively. Clinical guidelines on the prevention and treatment of chronic hepatitis B have been periodically updated based on emerging evidence from clinical research. The continuously improved reimbursement policy and the massively reduced price of antiviral drugs through government negotiation and central procurement have increased treatment accessibility and affordability. However, due to the low rates of diagnosis and treatment, China still faces a large challenge in achieving the 2030 goal of lowering HBV-related mortality by 65%. A public health approach involving concerted efforts from the government, medical community, industry, and society as a whole would be necessary to increase the uptake of HBV tests and treatment to achieve the global goal of eliminating viral hepatitis as a public health threat by 2030.

Abstract
Hepatocellular carcinoma (HCC) is a major contributor to cancer-related deaths worldwide. Hepatitis B virus (HBV) infection is a major etiologic factor leading to HCC. While there have been significant advancements in controlling HBV replication, achieving a complete cure for HBV-related HCC (HBV-HCC) remains an intricate challenge. HBV persistence is attributed to a myriad of mechanisms, encompassing both innate and adaptive immune responses. Regulatory T cells (Tregs) are pivotal in upholding immune tolerance and modulating excessive immune activation. During HBV infection, Tregs mediate specific T cell suppression, thereby contributing to both persistent infection and the mitigation of liver inflammatory responses. Studies have demonstrated an augmented expression of circulating and intrahepatic Tregs in HBV-HCC, which correlates with impaired CD8+ T cell function. Consequently, Tregs play a dual role in the context of HBV infection and the progression of HBV-HCC. In this comprehensive review, we discuss pertinent studies concerning Tregs in HBV infection, HBV-related cirrhosis and HCC. Furthermore, we summarize Treg responses to antiviral therapy and provide Treg-targeted therapies specific to HBV and HCC.

Abstract
High HBV DNA levels predispose to mother to child transmission (MTCT) of HBV. Early nucleotide analogue (NA) therapy can reduce HBV DNA and minimize MTCT. We analysed immune-metabolic profile in pregnant mothers who received NA from 2nd trimester compared with untreated mothers. In 2nd trimester, there was no difference in immune profiles between Gr.1 and Gr.2 but high viral load women had downregulated pyruvate, NAD+ metabolism but in 3rd trimester, Gr.1 had significant reduction in HBV-DNA, upregulated pyruvate and NAD with increased IFN-2αA, CD8Tcells, NK cells and decreased Tregs, IL15, IL18, IL29, TGFβ3 compared to Gr.2. In Gr.1, three eAg-ve women showed undetectable DNA and HBsAg. At delivery, Gr.1 showed no MTCT, with undetectable HBV DNA, HBsAg, high CD8 and NK cells in two women. We conclude, that starting NA from second trimester, reduces HBV load and MTCT, modulates NAD, induces immunity and suggest use of NA in early gestation in future trials.

Abstract
INTRODUCTION The World Health Organization (WHO) recommends tenofovir disoproxil fumarate (TDF) for pregnant women with hepatitis B virus (HBV) presenting with HBV DNA levels of 106 copies/mL or more to hinder mother-to-child transmission (MTCT). Moreover, it is suggested that neonates of HBV-infected mothers receive an HBV vaccine birth dose within 24 hours of birth to mitigate transmission risk. METHODOLOGY The study included 661 HBV-infected pregnant women and 316 infants from 3 hospitals in Southern Vietnam between October 2019 and November 2020. Infants were classified on the basis of their mothers' TDF prophylaxis into I-TDF (+) group (107 infants) whose mothers received TDF; I-TDF (-) group (56 infants) whose mothers missed TDF; and I-NTDF group (153 infants) whose mothers did not necessitate TDF. Almost all infants received an HBV vaccine birth dose with HBIG administered on the basis of parents' financial standing. RESULTS MTCT was found in 2.2% of the cases. The respective MTCT rates for I-TDF (+), I-TDF (-), and I-NTDF groups were 2.8%, 5.4%, and 0.7%. Immune response rates to the HBV vaccination in the total cohort, I-TDF (+), I-TDF (-), and I-NTDF groups, were 88.6%, 87.9%, 85.7%, and 90.2%, respectively. Vaccinated infants exhibited a statistically lower risk of HBV infection postbirth (aRR = 0.1; 95% confidence interval, 0.0-0.6; P = .01). CONCLUSION TDF can equate the MTCT risk in pregnant women with HBV DNA levels of 106 copies/mL or more to those with lower levels. Early administration of the HBV vaccine postbirth also effectively curtails MTCT. Thus, expanding TDF prophylaxis and vaccine coverage is pivotal to impede MTCT.

Am J Obstet Gynecol 2024; 230:249.e1-249.e8. [PMID: 37499992 DOI: 10.1016/j.ajog.2023.07.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Revised: 07/20/2023] [Accepted: 07/20/2023] [Indexed: 07/29/2023]
Abstract
BACKGROUND Amniocentesis is the most widely used invasive prenatal diagnostic sampling technique. However, whether this increases the risk of mother-to-child transmission of infectious diseases remains controversial. OBJECTIVE This study aimed to determine whether amniocentesis increases the risk of hepatitis B virus infection in infants who received standard prophylaxis, and to assess the related risk factors for mother-to-child transmission in women who underwent amniocentesis during pregnancy. STUDY DESIGN This retrospective analysis used the clinical data of pregnant women with hepatitis B virus infection at West China Second University Hospital, Sichuan University in 2019. After meeting the inclusion criteria, the participants were divided into 2 groups on the basis of whether they had undergone amniocentesis during pregnancy. The infant hepatitis B virus serologic status was followed 1 to 6 months after completion of immunization. The infant testing positive for hepatitis B surface antigen and negative for Hepatitis B surface antibody indicated mother-to-child transmission of hepatitis B virus. RESULTS In total, 1764 pregnant women with hepatitis B virus infection were enrolled. Of these, 846 underwent amniocentesis during pregnancy and 918 did not. All offspring received a standardized immunoprophylaxis schedule. The overall mother-to-child transmission rate for hepatitis B virus was 0.6% (5/846) in the amniocentesis group and 0.4% (4/918) in the control group (P=.745). Subgroup analysis showed that the mother-to-child transmission rate in hepatitis B e antigen-positive women was 1.8% (2/111) in the amniocentesis group and 1.0% (2/209) in the control group (P=.612). In women with high viral load, the mother-to-child transmission rate was 1.3% (1/78) vs 0.9% (1/107) (amniocentesis group vs control group; P=1.000). In the amniocentesis group, 31 amniotic fluid specimens had an abnormal appearance (bloody or brown). Univariate analysis showed that the mother-to-child transmission rates of these mothers were statistically higher than those of mothers with pale yellow or transparent amniotic fluid (2/31 vs 3/815; relative risk, 17.527 [3.037-101.151]; P=.012). CONCLUSION Amniocentesis did not increase the risk of mother-to-child transmission of hepatitis B virus in infants who received a standardized immunoprophylaxis schedule, including those with mothers who were hepatitis B e antigen-positive or had a high viral load. However, the abnormal appearance (bloody or brown) of the amniotic fluid obtained during amniocentesis may indicate increased risk of mother-to-child transmission for hepatitis B virus.

Abstract
OBJECTIVE To compare the efficacy and safety of telbivudine (LdT), tenofovir alafenamide fumarate (TAF), and tenofovir disoproxil fumarate (TDF) for preventing hepatitis B transmission in immune-tolerant pregnant women with HBV infection. METHODS We conducted a retrospective cohort study involving women who had hepatitis B virus deoxyribonucleic acid (HBV DNA) ≥ 2 × 105 IU/mL and initiated LdT, TDF, or TAF to prevent mother-to-child transmission (MTCT). The primary endpoint was the safety of mothers and infants. The secondary endpoints were maternal HBV DNA reduction at delivery and MTCT rate. RESULTS A total of 96 patients were enrolled in the study (LdT group, n = 36; TDF group, n = 35; TAF group, n = 25). All infants received hepatitis B virus immunoprophylaxis. The MTCT rate was 0%([0 of 25] vs. [0 of 35] vs. [0 of 36], p > .05). No severe liver function damage occurred in any of the mothers. Babies delivered in all groups had prenatal ultrasound screening abnormalities, but abnormality rates were not statistically significant between groups. CONCLUSION The application of TDF, TAF, or LdT to immune-tolerant HBV-infected pregnant women in middle-late pregnancy can successfully interrupt MTCT of the HBV virus. However, for all three groups of pregnant women who delivered babies with abnormal prenatal ultrasound screening, an expanded sample size may be needed for further observation.

Abstract
Reducing hepatitis B virus (HBV) mother-to-child transmission (MTCT) is a fundamental step toward the HBV elimination goal. The multicentred, multilevel SHIELD program aimed to use an intense intervention package to reduce HBV MTCT in China. This study was conducted in diverse health settings across China, encompassing 30,109 pregnant women from 178 hospitals, part of the interim analysis of stage II of the SHIELD program, and 8,642 pregnant women from 160 community-level health facilities in stage III of the SHIELD program. The study found that the overall MTCT rate was 0.23% (39 of 16,908; 95% confidence interval (CI): 0.16-0.32%) in stage II and 0.23% (12 of 5,290; 95% CI: 0.12-0.40%) in stage III. The MTCT rate was lower among participants who were compliant with the interventions (stage II: 0.16% (95% CI: 0.10-0.26%); stage III: 0.03% (95% CI: 0.00-0.19%)) than among those who were noncompliant (3.16% (95% CI: 1.94-4.85%); 1.91% (95% CI: 0.83-3.73%); P < 0.001). Our findings demonstrate that the comprehensive interventions among HBV-infected pregnant women were feasible and effective in dramatically reducing MTCT.

Abstract
BACKGROUND Hepatitis B mother-to-child transmission interruption (PMTCT) poses a formidable challenge in underdeveloped regions of China. This study aims to evaluate the effectiveness of PMTCT and the health management team (HMT) model in Ningxia, China, as well as the risk factors for adverse outcomes. METHODS The PMTCT + HMT model was established, and 360 pregnant women diagnosed with HBV infection in 2020-2022 were selected and divided into the control and the study groups based on different intervention modes. HBV serum markers and HBV DNA levels were assessed, the indicators of compliance behaviors and adverse outcomes were compared, and the factors influencing adverse outcomes were analyzed. RESULTS The majority of subjects were residents of the local city, married, with secondary school or higher education, and employees of public sectors. The proportion of ethnic minorities was 40.8% and 34.2% in the control group and study group. HBeAg positivity was 23.3% and 26.3%, and the proportion with HBV DNA levels ≥ 2 × 105 IU/mL was 9.2% and 7.1%. Compared with the control group (PMTCT alone), the PMTCT + HMT model led to improved maternal knowledge (17.5% vs. 57.1%), voluntary counseling (34.2% vs. 63.3%), and testing (37.5% vs. 70.4%). The incidence of adverse pregnancy outcomes ((including miscarriage, preterm birth) decreased significantly (17.5% vs. 6.2%), as did adverse neonatal outcomes (low birth weight and congenital HBV) (26.9% vs. 10.5%). Adverse outcomes were associated with low educational attainment, non-locals, unmarried status, and ethnic minority identity. Additionally, HBeAg positivity and HBV DNA levels ≥ 2 × 105 IU/mL were risk factors for adverse outcomes. CONCLUSIONS The PMTCT + HMT model demonstrates significant effectiveness in preventing mother-to-child transmission of hepatitis B in Ningxia. The unique demographic structure of Ningxia region is closely linked to poor outcomes, emphasizing the importance of monitoring HBeAg status and HBV DNA viral load level.

Mak LY, Koffas A, Dolman GE, Saleh H, Kemos P, Riddell A, Gill U, Kennedy PTF. Role of HBsAg levels in guiding hepatitis B virus prophylaxis in pregnancy: Insights from a multi-ethnic cohort. J Viral Hepat 2024; 31:3-11. [PMID: 37881873 DOI: 10.1111/jvh.13893] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 09/18/2023] [Accepted: 10/06/2023] [Indexed: 10/27/2023]
Abstract
Pregnant mothers with chronic hepatitis B infection (CHB) need peri-partum antiviral prophylaxis (PAP) to reduce the risk of mother-to-child-transmission. Currently, PAP is recommended in those with high viral load (VL) that is, HBV DNA >200,000 IU/mL. Quantitative hepatitis B surface antigen (qHBsAg) >10,000 IU/mL, a cut-off derived primarily from hepatitis B e-antigen (HBeAg) positive antenatal cohorts in Chinese populations, is advocated as a surrogate marker of VL for guiding PAP. We investigated the utility of qHBsAg to predict high-VL in a multi-ethnic urban cohort with CHB. A consecutive cohort of women with CHB was identified from Barts Health NHS Trust databases in the United Kingdom. We included women with paired HBV DNA and qHBsAg during pregnancy. Women already on antiviral at conception were excluded. A total of 769 pregnancies in 678 CHB pregnant mothers (median age 31 years-old, 8.6% HBeAg+) were included. At median gestational age of 15.3 weeks, HBV DNA was 336 (IQR 44-2998) IU/mL, with 65 (8.5%) being high-VL. Serum qHBsAg was most useful in Black/Black-British/Caribbean/African (AUROC 0.946) with 100% sensitivity and 80.6% specificity to predict high-VL; but it performed less well for other ethnicities: Asian (AUROC 0.877), White (AUROC 0.797) and mixed ethnicities (AUROC 0.742). In conclusion, for settings where healthcare resources are not limited, HBV DNA remains the optimal marker to identify highly viraemic pregnancies for guiding PAP. For resource-limited settings where the prevailing cost is treatment, serum qHBsAg can be used in Black/Black British/Caribbean/African sub-cohorts, but not for other ethnicities.

Abstract
Background Infection with the hepatitis B virus (HBV) poses a serious threat to global public health. More than 300 million instances of chronic hepatitis are brought on by it, which is the primary cause of liver disease. This study was conducted to determine the risk factors of HBV in children at Jinnah Postgraduate Medical Centre, Karachi, Sindh, Pakistan. Materials and methods This cross-sectional study was conducted at the Department of Gastroenterology, Jinnah Postgraduate Medical Centre, Karachi, Sindh, Pakistan from January 2019 to April 2022. A total of 134 children aged below 16 years with HBV were recruited in this study. Demographic information was recorded. Screening for HBV was done in all patients. Investigations including liver biochemistry, hepatitis B surface antigen (HBsAg), and HBV DNA polymerase chain reaction (PCR) were conducted in the hospital along with a complete blood count and ultrasound whole abdomen. All information was collected on a predesigned proforma and evaluated using statistical package for the social sciences (SPSS), version 25.0, software. Results The mean age of patients was 11.02 ± 2.19 years. There were 57.46% males. The frequent risk factor was vertical transmission in 47% of children followed by blood transfusion in 23.9% of children, horizontal transmission in 13.4% of children, and prior history of surgical or dental intervention in 17.2% of children. Conclusion In this study, vertical transmission was the most common route of transmission of HBV. Additionally, 11% of family members were HBV positive. None had concomitant hepatitis C virus (HCV) and HDV infection. All pregnant females should be screened. Children on chronic blood transfusion therapy should be screened annually. Additionally, birth-dose HBV vaccination should be implemented as a key step in HBV prevention among Pakistani children. How to cite this article Butt N, Kamani L, Khemani H.

Impact of timing on protection of combined immunoprophylaxis in preventing mother-to-child transmission of hepatitis B virus: a retrospective study. J Matern Fetal Neonatal Med 2023; 36:2257837. [PMID: 37699774 DOI: 10.1080/14767058.2023.2257837] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Revised: 08/16/2023] [Accepted: 09/06/2023] [Indexed: 09/14/2023]
Abstract
Objective: To evaluate the impact of timing combined immunoprophylaxis on mother-to-child transmission (MTCT) of the hepatitis B virus (HBV) in pregnant women living with hepatitis B. Methods: A retrospective cohort study was included HBsAg-positive pregnant women who delivered full-term at Tianjin Third Central Hospital from January 2019 to December 2021. The objective of this study is to determine whether early administration of hepatitis B immune globulin (HBIG) and the first dose of hepatitis B vaccination after birth can further improve protection. Result: A total of 694 pregnant women living with hepatitis B were included; 93 infants from these mothers were lost to follow-up [including moving (n = 21), emigrating (n = 26), changing contact information (n = 27), and other reasons (n = 19)], leaving 601 infants for analysis. The incidence in babies born to mothers with hepatitis B was 1.50% (9/601). Based on the different timing of combined immunoprophylaxis administration after birth, 601 infants were divided into two groups (within 2 h and within 2-12 h). The incidence in babies born to mothers with hepatitis B were 0.32% (1/308) and 2.73% (8/293) for infants who received combined immunoprophylaxis within 2 h and between 2 and 12 h of birth, respectively (p = 0.037). The infection incidence of infants born to HBeAg-positive mothers and HBeAg-positive mothers who did not receive antiviral treatment during pregnancy was lower in the 2-h group compared to the 2-12 h group (0.72% vs. 5.84%, p = 0.04 and 1.20% vs. 9.46%, p = 0.047). Conclusion: Using combined immunoprophylaxis as soon as possible (within two hours of birth) may protect against MTCT of HBV more.

Abstract
PURPOSE OF REVIEW Coinfection with HIV and hepatitis B virus (HBV) is common owing to shared routes of transmission, and persons with HIV-HBV coinfection experience an accelerated progression of liver disease. Despite the widespread availability of HBV vaccination, rates of seroprotection in people living with HIV (PLWH) have historically been low. In this article, we review strategies in HBV prevention among PLWH, focusing specifically on updates in HBV vaccination and chemoprophylaxis. RECENT FINDINGS Vaccination remains the hallmark of HBV prevention, and recent studies suggest that a double dose of HBV vaccine and Heplisav-B can improve rates of seroprotection among PLWH. The use of tenofovir-containing antiretroviral therapy (ART) has similarly been shown to provide some HBV protection in PLWH; however, this protection can be lost when switching to newer tenofovir-sparing regimens, including long-acting injectables. All HBV-susceptible persons with HIV should be vaccinated against HBV, regardless of ART regimen and CD4 count.

Abstract
BACKGROUND Studies have shown acute flares of chronic hepatitis B (CHB) might be related to immunologic changes that occur during pregnancy. However, the indicators for predicting acute flares of CHB among pregnant women still need further study. We aimed to distinguish the relevance between serum levels of HBcrAg and acute flares of CHB in pregnant women in the immune-tolerant phase of chronic HBV infection after short-course antiviral therapy. METHODS A total of 172 chronic HBV-infected pregnant women who were judged to be in the immune-tolerant phase were recruited in our research. All patients received short-course antiviral therapy with TDF. The biochemical, serological, and virological parameters were measured using standard laboratory procedures. The serum levels of HBcrAg were tested by ELISA. RESULTS Fifty-two (30.2%) out of 172 patients had acute flares of CHB. At postpartum week 12 (TDF cessation), serum HBcrAg (OR, 4.52; 95% CI, 2.58-7.92) and HBsAg (OR, 2.52; 95% CI, 1.13-5.65) were associated with acute flares of CHB. The serum HBcrAg levels were beneficial for confirmation of patients with acute flares of CHB, with an area under the ROC curve of 0.84 (95% CI, 0.78-0.91). CONCLUSIONS For pregnant women with chronic HBV infection in the immune-tolerant phase, serum HBcrAg and HBsAg levels at postpartum week 12 were associated with acute flares of CHB after short-course antiviral therapy with TDF. The serum HBcrAg level can correctly identify acute flares of CHB and may be a predictor of the need for continuing antiviral therapy after 12 weeks postpartum.

BMC Gastroenterol 2023; 23:387. [PMID: 37951866 PMCID: PMC10640741 DOI: 10.1186/s12876-023-02966-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Accepted: 09/20/2023] [Indexed: 11/14/2023] Open
Abstract
BACKGROUND The majority of HBeAg-positive mothers with chronic hepatitis B have high levels of viremia and inactive disease with normal alanine aminotransferase (ALT) during pregnancy. In addition, postpartum disease activation and ALT flare have been reported in the range of 15 - 35%. However, the current International Association Guidelines have not provided clear recommendations and a risk-stratified monitoring schedule. Furthermore, data are lacking on the definition of normal ALT in the postpartum period in mothers with chronic hepatitis B. The clinical features and ALT flare patterns in HBeAg-positive mothers versus HBeAg-negative mothers are not fully explored. Thus, we design a cohort study to investigate the aforementioned area and generate data to assist healthcare providers in better managing mothers with hepatitis B. We aim to assess the frequency of postpartum ALT flares and predictors for such events. METHOD This study is a single-center and prospective cohort study (n = 360) that consists of two groups of patients including HBsAg-positive mothers (n = 120) and healthy mothers without HBV infection (n = 240). In HBeAg-positive mothers, antiviral therapy during late pregnancy is permitted to prevent Mother-to-child transmission (MTCT) but discontinued at delivery if there is no further indication for the treatment. Mothers are enrolled at the gestational weeks of 12-24. After delivery, both mothers and their infants will be followed up until postpartum week 24. Clinical and laboratory data are collected every 4 weeks during the study except there are no follow-up visits at the postpartum weeks 16 and 20. The primary objective is the proportion of patients with postpartum ALT flares. The secondary objectives are independent risk factors during pregnancy for predicting postpartum ALT flares and the normal range of postpartum ALT levels in healthy mothers. DISCUSSION The current study focuses on the incidence of postpartum ALT flares in mothers with chronic hepatitis B including subgroup analysis based on HBeAg status. The data will have several clinical implications, such as providing evidence for an appropriate monitoring schedule in CHB mothers after delivery. Further analyses on predictors of such events may assist clinicians in identifying mothers who might develop severe postpartum ALT flares. The data generated from healthy mothers have the potential to identify the patterns of ALT changes during pregnancy and postpartum, so we can gain a better understanding of the normal range of ALT in this subpopulation.

Abstract
Maternal-to-child transmission of hepatitis B virus (HBV) and hepatitis delta virus (HDV) can lead to the risk of progressive liver disease in infants, but fortunately effective interventions exist to decrease transmission. Counseling on the risk of maternal-to-child transmission, care pathways to decrease transmission, and the implications of HBV and HDV on pregnancy outcomes are the key components of caring for pregnant people living with HBV and HDV.

Abstract
AIM To investigate the immune status of Chinese chronic hepatitis B (CHB) pregnant women and their clinical characteristics. METHODS About 1544 CHB pregnant women without antiviral therapy from 2013 to 2018 were selected from the hospital records. The definition of immune status is based on American Association for the Study of Liver Diseases (AASLD) 2018 Hepatitis B Guidance, and those who did not meet any criteria of the immune status were referred to in the gray zones (GZ). RESULTS There were 284 patients in the immune-tolerance phase, 72 patients in the HBeAg-positive immune active phase, 553 patients in the inactive phase, 61 patients in the HBeAg-negative immune active phase. Of note, 574 (37.18%) patients did not fit into any of the above phases were defined as the GZ. Patients with elevated ALT had a higher rate of intrahepatic cholestasis of pregnancy (ICP). Mother to child HBV transmission was rare (only two cases) and occurred in mothers in the immune-tolerant phase. CONCLUSIONS Our data showed that more than one-third of CHB pregnant women were classified into the GZ. In standard stages, advanced age is associated with HBeAg-negative and a higher cesarean rate in the inactive phase. The incidence of ICP was higher in immune active phases, including GB and GD. The probability of mother-to-child transmission in gray zones is low.

Abstract
Liver disease is not uncommon during pregnancy and is associated with increased maternal and fetal/neonatal morbidity and mortality. Physiological changes during pregnancy, including a hyperestrogenic state, increase in circulating plasma volume and/or reduction in splanchnic vascular resistance, and hemostatic imbalance, may mimic or worsen liver disease. For the clinician, it is important to distinguish among the first presentation or exacerbation of chronic liver disease, acute liver disease non-specific to pregnancy, and pregnancy-specific liver disease. This last group classically includes conditions such as hyperemesis gravidarum, intrahepatic cholestasis of pregnancy, liver disorders associated with the pre-eclampsia spectrum, and an acute fatty liver of pregnancy. All of these disorders often share pathophysiological mechanisms, symptoms, and laboratory findings (such as elevated liver enzymes), but a prompt and correct diagnosis is fundamental to guide obstetric conduct, reduce morbidity and mortality, and inform upon the risk of recurrence or development of other chronic diseases later on in life. Finally, the cause of elevated liver enzymes during pregnancy is unclear in up to 30-40% of the cases, and yet, little is known on the causes and mechanisms underlying these alterations, or whether these findings are associated with worse maternal/fetal outcomes. In this narrative review, we aimed to summarize pragmatically the diagnostic work-up and the management of subjects with elevated liver enzymes during pregnancy.

Abstract
Hepatitis B is a major global health problem with high morbidity and mortality. Approximately 296 million people are living with chronic HBV, and 1.5 million new infections are detected each year, even though a highly effective vaccine has been available for decades and viral replication and transmission can be contained with the use of drugs. Nucleoside therapy, while not curative in most cases, can control viral replication, improve prognosis, and prevent mother-to-child transmission safely. Current treatment guidelines do not include a significant number of chronically infected patients or pregnant women and are often complex to implement. Since these populations continue to have a detectable HVB viral load, they could perpetuate transmission. Expanding and facilitating treatment indications, including treatment as a public health intervention, could help control the spread of the HBV pandemic, thus bringing us closer to the goal of the United Nations General Assembly for the year 2030.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death worldwide. The incidence of HCC is affected by genetic and non-genetic factors. Genetically, mutations in the genes, tumor protein P53 (TP53), catenin beta 1 (CTNNB1), AT-rich interaction domain 1A (ARIC1A), cyclin dependent kinase inhibitor 2A (CDKN2A), mannose 6-phosphate (M6P), smooth muscle action against decapentaplegic (SMAD2), retinoblastoma gene (RB1), cyclin D, antigen presenting cells (APC), AXIN1, and E-cadherin, have been shown to contribute to the occurrence of HCC. Non-genetic factors, including alcohol consumption, exposure to aflatoxin, age, gender, presence of hepatitis B (HBV), hepatitis C (HCV), and non-alcoholic fatty liver disease (NAFLD), increase the risk of HCC. RECENT FINDINGS The severity of the disease and its occurrence vary based on geographical location. Furthermore, men and minorities have been shown to be disproportionately affected by HCC, compared with women and non-minorities. Ethnicity has been reported to significantly affect tumorigenesis and clinical outcomes in patients diagnosed with HCC. Generally, differences in gene expression and/or the presence of comorbid medical diseases affect or influence the progression of HCC. Non-Caucasian HCC patients are significantly more likely to have poorer survival outcomes, compared to their Caucasian counterparts. Finally, there are a number of factors that contribute to the success rate of treatments for HCC. CONCLUSION Assessment and treatment of HCC must be consistent using evidence-based guidelines and standardized outcomes, as well as international clinical practice guidelines for global consensus. Standardizing the assessment approach and method will enable comparison and improvement of liver cancer research through collaboration between researchers, healthcare providers, and advocacy groups. In this review, we will focus on discussing epidemiological factors that result in deviations and changes in treatment approaches for HCC.

Abstract
Liver diseases in pregnancy comprise both gestational liver disorders and acute and chronic hepatic disorders occurring coincidentally in pregnancy. Whether related to pregnancy or pre-existing, liver diseases in pregnancy are associated with a significant risk of maternal and fetal morbidity and mortality. Thus, the European Association for the Study of Liver Disease invited a panel of experts to develop clinical practice guidelines aimed at providing recommendations, based on the best available evidence, for the management of liver disease in pregnancy for hepatologists, gastroenterologists, obstetric physicians, general physicians, obstetricians, specialists in training and other healthcare professionals who provide care for this patient population.

Abstract
Hepatitis B (HBV) is a major cause of global morbidity and mortality, and the leading cause of liver cancer worldwide. Significant advances have recently been made toward the development of a finite HBV treatment that achieves permanent loss of HBsAg and HBV DNA (so-called "HBV cure"), which could provide the means to eliminate HBV as a public health threat. However, the HBV cure is just one step toward achieving WHO HBV elimination targets by 2030, and much work must be done now to prepare for the successful implementation of the HBV cure. In this review, we describe the required steps to rapidly scale-up future HBV cure equitably. We present key actions required for successful HBV cure implementation, integrated within the World Health Organization (WHO) Global Health Sector Strategy (GHSS) 2022-2030 framework. Finally, we highlight what can be done now to progress toward the 2030 HBV elimination targets using available tools to ensure that we are preparing, but not waiting, for the cure.

Abstract
OBJECTIVE To describe the anti-hepatitis B virus (HBV) efficacy, HBeAg serologic changes, HBV perinatal transmission, and safety in pregnant women who are living with human immunodeficiency virus (HIV) and HBV co-infection who were randomized to various antiretroviral therapy (ART) regimens. METHODS The PROMISE (Promoting Maternal and Infant Survival Everywhere) trial was a multicenter randomized trial for ART-naive pregnant women with HIV infection. Women with HIV and HBV co-infection at 14 or more weeks of gestation were randomized to one of three ART arms: one without HBV treatment (group 1) and two HBV treatment arms with single (group 2) or dual anti-HBV activity (group 3). The primary HBV outcome was HBV viral load antepartum change from baseline (enrollment) to 8 weeks; safety assessments included alanine aminotransferase (ALT) level, aspartate aminotransferase (AST) level, and anemia (hemoglobin less than 10 g/dL). Primary comparison was for the HBV-active treatment arms. Pairwise comparisons applied t test and the Fisher exact tests. RESULTS Of 3,543 women, 3.9% were HBsAg-positive; 42 were randomized to group 1, 48 to group 2, and 48 to group 3. Median gestational age at enrollment was 27 weeks. Among HBV-viremic women, mean antepartum HBV viral load change at week 8 was -0.26 log 10 international units/mL in group 1, -1.86 in group 2, and -1.89 in group 3. In those who were HBeAg-positive, HBeAg loss occurred in 44.4% at delivery. Two perinatal HBV transmissions occurred in group 2. During the antepartum period, one woman (2.4%) in group 1 had grade 3 or 4 ALT or AST elevations, two women (4.2%) in group 2, and three women (6.3%) in group 3. CONCLUSION Over a short period of time, HBV DNA suppression was not different with one or two HBV-active agents. HbeAg loss occurred in a substantial proportion of participants. Perinatal transmission of HBV infection was low. Hepatitis B virus-active ART was well-tolerated in pregnancy, with few grade 3 or 4 ALT or AST elevations.

Possible Association between Genetic Diversity of Hepatitis B Virus and Its Effect on the Detection Rate of Hepatitis B Virus DNA in the Placenta and Fetus. Viruses 2023; 15:1729. [PMID: 37632070 PMCID: PMC10458115 DOI: 10.3390/v15081729] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 08/10/2023] [Accepted: 08/10/2023] [Indexed: 08/27/2023] Open
Abstract
Background: The prevalence of HBV infection and HBV genotypes varies from country to country, and the role of HBV genotypes in the presence of HBV in the placenta and fetus has never been explored. This study was conducted to (1) identify HBV genotypes, and their frequencies, that infected Northern Thai pregnant women; (2) evaluate the association between HBV genotypes and the detection rate of HBV DNA in the placenta and fetus; (3) evaluate the association between specific mutations of the HBV genome and HBV DNA detection in placental tissue; and (4) identify the mutation of the HBV genome that might occur between maternal blood, placenta, and cord blood. Methods: Stored samples of the maternal blood, placental tissue, and cord blood that were collected from 145 HBsAg-positive pregnant Thai women were analyzed to identify HBV DNA. Results: Approximately 25% of infected mothers had fetal HBV DNA detection, including cases with concomitant HBV DNA detection in the placenta (77.3%). A total of 11.7% of cases with placental detection had no HBV DNA detection in the maternal blood, indicating that the placenta could be a site of HBV accumulation. Of the 31 HBV-positive blood samples detected by nested PCR, the detected strains were subgenotype C1 (77.4%), subgenotype B9 (9.7%), and subgenotype C2, B2, B4, and recombinant B4/C2 (3.2% for each). Genotype B had a trend in increased risk of placental HBV DNA detection compared to genotype C, with a relative risk of 1.40 (95% CI: 1.07-1.84). No specific point mutation had a significant effect on HBV DNA detection in placental tissue. Mutation of C454T tended to enhance HBV DNA detection in placental tissue, whereas T400A tended to have a lower detection rate. No mutation was detected in different sample types collected from the same cases. Conclusions: HBV DNA detection in the fetus was identified in approximately 25% of HBV-positive mothers, associated with the presence of HBV in the placenta in most cases. The placenta could possibly be a site of HBV accumulation. Subgenotype C1 was the most common subgenotype, followed by subgenotype B9. HBV genotype B possibly had a higher trend in intrauterine detection than HBV genotype C. Mutation is unlikely to occur during intrauterine exposure.

Abstract
Chronic hepatitis B virus (HBV) infection leads to the development of cirrhosis and hepatocellular carcinoma. Lifelong treatment with nucleotides/nucleoside antiviral agents is effective at suppressing HBV replication, however, adherence to daily therapy can be challenging. This review discusses recent advances in the development of long-acting formulations for HBV treatment and prevention, which could potentially improve adherence. Promising new compounds that target distinct steps of the virus life cycle are summarized. In addition to treatments that suppress viral replication, curative strategies are focused on the elimination of covalently closed circular DNA and the inactivation of the integrated viral DNA from infected hepatocytes. We highlight promising long-acting antivirals and genome editing strategies for the elimination or deactivation of persistent viral DNA products in development.

Abstract
Prevention of mother-to-child transmission of hepatitis B virus (HBV) infection is a cornerstone of efforts to support progress towards elimination of viral hepatitis. Current guidelines recommend maternal screening, antiviral therapy during the third trimester of high-risk pregnancies, universal and timely HBV birth dose vaccination, and post-exposure prophylaxis with hepatitis B immunoglobulin for selected neonates. However, serological and molecular diagnostic testing, treatment and HBV vaccination are not consistently deployed, particularly in many high endemicity settings, and models predict that global targets for reduction in paediatric incidence will not be met by 2030. In this article, we briefly summarise the evidence for current practice and use this as a basis to discuss areas in which prevention of mother-to-child transmission can potentially be enhanced. By reducing health inequities, enhancing pragmatic use of resources, filling data gaps, developing advocacy and education, and seeking consistent investment from multilateral agencies, significant advances can be made to further reduce vertical transmission events, with wide health, societal and economic benefits.

Abstract
The aim of the work is to assess the prevalence of hepatitis B virus drug resistance mutations and immune escape mutations in pregnant women in the Republic of Guinea. MATERIALS AND METHODS Blood plasma samples obtained from 480 pregnant women from different regions of the Republic of Guinea with laboratory-confirmed viral hepatitis B were studied. Nucleotide sequences for genotype identification and mutation detection were obtained using nested-PCR followed by Sanger sequencing, based on overlapping pairs of primers spanning the complete genome of the virus. RESULTS AND DISCUSSION In the examined group, the viral genotype E was the most prevalent (92.92%) compared with subgenotypes A1 (1.67%), A3 (1.46%), D1 (0.63%), D2 (1.04%) and D3 (2.29%). Among the examined HBV-infected pregnant women, 188 (39.17%) had undetectable HBsAg. Drug resistance mutations were detected in 33 individuals, which amounted to 6.88%. The following mutations were found: S78T (27.27%), L80I (24.24%), S202I (15.15%), M204I/V (42.42%). The presence of polymorphic variants not described as drug resistant has also been shown in positions associated with the development of drug resistance to tenofovir, lamivudine, telbivudine and entecavir (L80F, S202I, M204R). When analyzing the MHR and the region of a determinant, mutations were detected in 318 (66.25%) of pregnant women. In 172 of them, which amounted to 54.09%, multiple mutations were found. The amino acid substitutions in 13 positions associated with HBsAg-negative hepatitis B and/or potentially affecting HBsAg antigenicity were identified. CONCLUSION The high prevalence of immune escape and drug resistance mutations potentially associated with false-negative result of HBsAg screening, prophylaxis failure, and virological failure of therapy that has been identified among treatment naive pregnant women imposes a serious problem.

Abstract
BACKGROUND In 2020, WHO recommended the addition of peripartum antiviral prophylaxis (PAP) to hepatitis B birth dose vaccination (HepB-BD) and hepatitis B infant vaccination (HepB3) to reduce mother-to-child transmission of hepatitis B virus (HBV) infection in pregnant women who have a marker of high infectivity (ie, HBV DNA ≥200 000 international units per mL or HBeAg-positive). We aimed to evaluate the impact and cost-effectiveness of this recommendation and of a theoretical simplified strategy whereby PAP is given to all pregnant women who are HBsAg-positive without risk stratification. METHODS This modelling study used a dynamic simulation model of the HBV epidemic in 110 countries in all WHO regions, structured by age, sex, and country. We assessed three strategies of scaling up PAP for pregnant women: PAP for those with high viral load (PAP-VL); PAP for those who are HBeAg-positive (PAP-HBeAg); and PAP for all pregnant women who are HBsAg-positive (PAP-universal), in comparison with neonatal vaccination alone (HepB-BD). We investigated how different diagnostic and antiviral drug costs affected the cost-effectiveness of the strategies evaluated. Using a health-care provider perspective, we calculated incremental cost-effectiveness ratios in cost (US$) per disability-adjusted life-year (DALY) averted in each country's population and compared these with country-specific cost-effectiveness thresholds. We also calculated new neonatal infections averted for each of the strategies. FINDINGS Adding PAP-VL to HepB-BD could avert around 1·1 million (95% uncertainty interval 1·0 million-1·2 million) new neonatal infections by 2030 and around 3·2 million (95% uncertainty interval 3·0 million-3·4 million) new neonatal infections and approximately 8·8 million (7·8 million-9·7 million) DALYs by 2100 across all the countries modelled. This strategy would probably be cost-effective up to 2100 in 28 (26%) of 106 countries analysed (which included some of the countries that have the greatest HBV burden) if costs are as currently expected to be, and in 74 (70%) countries if diagnostic and monitoring costs were lowered (by about 60-75%). The relative cost-effectiveness of PAP-VL and PAP-HBeAg was finely balanced and depended on the respective diagnostic and monitoring costs. The PAP-universal strategy could be more cost-effective than either of these strategies in most countries, but the use of antiviral treatment could be five times as high than with PAP-VL. INTERPRETATION PAP can provide substantial health benefits, and, although the current approach might already be cost-effective in some high-burden settings, decreased diagnostic costs would probably be needed for PAP to be cost-effective in most countries. Therefore, careful consideration needs to be given about how such a strategy is implemented, and securing reduced costs for diagnostics should be a priority. The theoretical strategy of offering PAP to all women who are HBsAg-positive (eg, if diagnostic tests to identify mothers at risk of transmission are not available) could be a cost-effective alternative, depending on prevailing costs of diagnostics and antiviral therapy.

Antivirals for prevention of hepatitis B virus mother-to-child transmission in human immunodeficiency virus positive pregnant women co-infected with hepatitis B virus. Cochrane Database Syst Rev 2023; 6:CD013653. [PMID: 37306558 PMCID: PMC10259198 DOI: 10.1002/14651858.cd013653.pub2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 06/13/2023]
Abstract
BACKGROUND Hepatitis B virus (HBV)-human Immunodeficiency virus (HIV) co-infection promotes an aggressive disease course of HBV infection. In the only available non-Cochrane systematic review on antiviral therapy during pregnancy for prevention of mother-to-child transmission of HBV, none of the women studied had HBV-HIV co-infection but were either HBV- or HIV-seropositive. Treatment of HBV alone may develop HIV-strains that are resistant to non-nucleoside reverse transcriptase inhibitors. Accordingly, co-treatment of the HIV infection is recommended. OBJECTIVES To evaluate the benefits and harms of tenofovir-based antiviral combination regimens versus placebo, tenofovir alone, or non-tenofovir-based antiviral regimen either alone or in combination with HBV for the prevention of mother-to-child transmission of HBV in HIV-positive pregnant women co-infected with HBV. SEARCH METHODS We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, Cochrane Central Register of Controlled Trials, MEDLINE Ovid, Embase Ovid, LILACS (Bireme), Science Citation Index Expanded (Web of Science), and Conference Proceedings Citation Index-Science (Web of Science) on 30 January 2023. We manually searched the reference lists of included trials, searched on-line trial registries, and contacted experts in the field and pharmaceutical companies for any further potential trials. SELECTION CRITERIA We aimed to include randomised clinical trials comparing tenofovir-based antiviral combination regimens (anti-HIV regimen with lopinavir-ritonavir therapy, or any other antiviral therapy, and two drugs with activity against HBV, specifically, tenofovir alafenamide (TAF) or tenofovir disoproxil fumarate (TDF), plus lamivudine or emtricitabine) with placebo alone, or tenofovir alone, or non-tenofovir-based antiviral regimen (zidovudine, lamivudine, telbivudine, emtricitabine, entecavir, lopinavir-ritonavir, or any other antiviral therapy) either alone or in combination with at least two other antivirals. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. Primary outcomes included all-cause infant mortality, proportion of infants with serious adverse events, proportion of infants with HBV mother-to-child transmission, all-cause maternal mortality, and proportion of mothers with serious adverse events. Secondary outcomes included proportion of infants with adverse events not considered serious, proportion of mothers with detectable HBV DNA (deoxyribonucleic acid) (before delivery), maternal hepatitis B e antigen (HBeAg) to HBe-antibody seroconversion (before delivery) and maternal adverse events not considered serious. We used RevMan Web to carry out analyses and presented results, where feasible, using a random-effects model and risk ratios (RR) with 95% confidence intervals (CIs). We performed sensitivity analysis. We assessed risk of bias using predefined domains, assessed the certainty of the evidence using GRADE, controlled risk of random errors with Trial Sequential Analysis, and presented outcome results in a summary of findings table. MAIN RESULTS Five completed trials were included, of which four trials contributed data to one or more of the outcomes. They included a total of 533 participants randomised to tenofovir-based antiviral combination regimens (196 participants) versus control (337 participants). The control groups received non-tenofovir-based antiviral regimens either as zidovudine alone (three trials) or as a combination of zidovudine, lamivudine and lopinavir-ritonavir (five trials). None of the trials used placebo or tenofovir alone. All trials were at unclear risk of bias. Four trials used intention-to-treat analyses. In the remaining trial, two participants in the intervention group and two in the control group were lost to follow-up. However, the outcomes of these four participants were not described. Tenofovir-based antiviral combination regimen versus control We are very uncertain about the effect of a tenofovir-based antiviral combination regimen versus control on all-cause infant mortality (RR 2.24, 95% CI 0.72 to 6.96; participants = 132; trials = 1; very low-certainty evidence); proportion of infants with serious adverse events (RR 1.76, 95% CI 1.27 to 2.43; participants = 132; trials = 1; very low-certainty evidence), and proportion of mothers with serious adverse events (RR 0.90, 95% CI 0.62 to 1.32; participants = 262; trials = 2; very low-certainty evidence). No trial reported data on the proportion of infants with HBV mother-to-child transmission and all-cause maternal mortality. We are also very uncertain about the effect of tenofovir-based antiviral combination regimens versus control on the proportion of infants with adverse events not considered serious (RR 0.94, 95% CI 0.06 to 13.68; participants = 31; trials = 1; very low-certainty evidence), and proportion of mothers with detectable HBV DNA (before delivery) (RR 0.66, 95% CI 0.42 to 1.02; participants = 169; trials = 2; very low-certainty evidence). No trial reported data on maternal hepatitis B e antigen (HBeAg) to HBe-antibody seroconversion (before delivery) and maternal adverse events not considered serious. All trials received support from industry. AUTHORS' CONCLUSIONS We do not know what the effects of tenofovir-based antiviral combination regimens are on all-cause infant mortality, proportion of infants with serious adverse events and proportion of mothers with serious adverse events, proportion of infants with adverse events not considered serious, and proportion of mothers with detectable HBV DNA before delivery because the certainty of evidence was very low. Only one or two trials, with insufficient power, contributed data for analyses. We lack randomised clinical trials at low risk of systematic and random errors, and fully reporting all-cause infant mortality, serious adverse events and reporting on clinical and laboratory outcomes, such as infants with HBV mother-to-child transmission, all-cause maternal mortality, maternal hepatitis B e antigen (HBeAg) to HBe-antibody seroconversion before delivery and maternal adverse events not considered serious.

Abstract
BACKGROUND Antiviral intervention in hepatitis B virus (HBV)-infected pregnant women can effectively reduce mother-to-child transmission. However, the immunological characteristics of pregnant women with chronic HBV infection and the effects of antiviral intervention during pregnancy on maternal immune response remain unknown. We aimed to investigate these effects by comparing mothers who received antiviral intervention during pregnancy with those who did not. METHODS Pregnant women positive for hepatitis B surface antigen and hepatitis B e-antigen (HBsAg+ HBeAg+) were enrolled at delivery, including 34 received prophylactic antiviral intervention during pregnancy (AVI mothers) and 15 did not (NAVI mothers). T lymphocyte phenotypes and functions were analysed using flow cytometry. RESULTS At delivery, maternal regulatory T cell (Treg) frequency in AVI mothers was significantly higher than that in NAVI mothers (P < 0.002), and CD4+ T cells in AVI mothers displayed a decreased ability to secrete IFN-γ (P = 0.005) and IL-21 (P = 0.043), but an increased ability to secrete IL-10 and IL-4 (P = 0.040 and P = 0.036), which represented a higher Treg frequency, enhanced Th2 response and suppressed Th1 response. Treg frequency among AVI mothers was correlated negatively with serum HBsAg and HBeAg levels. After delivery, the ability of CD4+ T cells or CD8+ T cells to secrete IFN-γ or IL-10 was similar and no significant difference in Treg frequency was found between the two groups. CONCLUSIONS Prophylactic antiviral intervention during pregnancy has an effect on T cell immunity in pregnant women, which was characterised by increased maternal Treg frequency, enhanced Th2 response and suppressed Th1 response at delivery.

Abstract
Chronic hepatitis B virus (HBV) infection affects about 296 million people worldwide and is the leading aetiology of cirrhosis and liver cancer globally. Major medical complications also include acute flares and extrahepatic manifestations. In addition, people living with HBV infection also experience stigma. HBV-related cirrhosis resulted in an estimated 331,000 deaths in 2019, and it is estimated that the number of deaths from HBV-related liver cancer in 2019 was 192,000, an increase from 156,000 in 2010. Meanwhile, HBV remains severely underdiagnosed and effective measures that can prevent infection and disease progression are underutilized. Birth dose coverage for HBV vaccines remains low, particularly in low-income countries or regions where HBV burden is high. Patients with HBV infection are inadequately evaluated and linked to care and are undertreated worldwide, even in high-income countries or regions. Despite the goal of the World Health Organization to eliminate viral hepatitis as a public health problem by 2030, the annual global deaths from HBV are projected to increase by 39% from 2015 to 2030 if the status quo remains. In this Review, we discuss the current status and future projections of the global burden of HBV infection. We also discuss gaps in the current care cascade and propose future directions.

Abstract
GOALS The study is to evaluate the efficacy and long-term safety of telbivudine (LdT) usage for hepatitis B surface antigen (HBsAg) positive pregnant women with high viral load. BACKGROUND The efficacy and safety of LdT during pregnancy were not assessed from a long-term perspective. STUDY HBsAg-positive pregnant women were enrolled and grouped according to antiviral initiation time. Group A (n=100) and group B (n=100) were treated with LdT initiated in the second or third trimester. Group C (n=90) received no antiviral treatment. The efficacy and safety of LdT treatment were compared and infants were followed-up at 1, 5, and 10 years. Denver developmental screening test was conducted at 5 years. RESULTS Viral loads before delivery in LdT-treated groups were lower than that in group C and group A was lower than that in group B ( P <0.001). No infants in LdT-treated groups were infected whereas 8.8% (8/90) infants in group C had positive HBsAg (χ 2 =23.20, P <0.001). All LdT-treated mothers were well tolerated and no LdT-related adverse events in infants were reported. Part of the physical growth index of infants was higher than Chinese standard values (SV) and showed significant differences. In groups A and B, the developmental screening test qualified rate of 100% (48/48) and 97.96% (48/49) showed no significant difference compared with 92% in normal Chinese children (χ 2 =5.72, P =0.06). CONCLUSIONS Treatment initiated during the second trimester could strengthen the success of mother-to-child transmission blockage. LdT treatment during pregnancy is safe for both mothers and infants in the long term.

Abstract
OBJECTIVE Tenofovir disoproxil fumarate (TDF) is recommended for the prevention of mother-to-infant transmission of the hepatitis B virus (HBV). This study investigated the safety of infants whose mothers continued to receive TDF while breastfeeding. PATIENTS AND METHOD Thirty women taking TDF daily from the second or third trimester of pregnancy to three months postpartum were enrolled. Tenofovir (TFV) concentrations in breast milk were determined and compared with those in umbilical cord (UC) blood and amniotic fluid. Infant growth parameters were assessed at birth, and at 3, 6, and 12 months. TFV uptake experiments were conducted in vitro to elucidate the mechanisms of TFV exposure via breast milk. RESULTS TFV concentrations in breast milk ranged from 1.4 to 11.7 ng/mL within 24 h after dosing in the third month postpartum. The median trough concentration of TFV in breast milk was 3.7 (interquartile range, 2.6-6.2) ng/mL, which is lower than that in UC blood (median = 53.5 ng/mL) and amniotic fluid (median = 531.0 ng/mL). The low permeability of TFV in MCF-10A cells may explain the minimal exposure to TFV in breast milk. Body weights, body lengths, and head circumferences of the breastfed infants were comparable to the national standards for physical development. CONCLUSION Infant exposure to TFV from breast milk is much lower than the exposure from placental transfer and swallowing from amniotic fluid. The physical growth parameters of all infants in this study were normal. The findings indicate that breastfeeding is safe for infants of HBV-infected mothers who continue to receive TDF through three months postpartum.

Abstract
Viral infections pose unique threats to pregnant persons and their infants. As the frequency of epidemics caused by novel pathogens increases, understanding pregnancy-specific considerations for antiviral treatments is critical for obstetric and nonobstetric providers alike. The use of pharmacologic therapeutics in pregnancy, which include antivirals, pathogen-specific antibodies, and vaccines, is limited due to the lack of purposeful, methodologic, pharmacometrics analyses in this special population. Our current understanding regarding dosing, safety, and efficacy stems from our knowledge of potential maternal or neonatal risks, observational data, and rarely clinical trials. In this review, we provide an overview on the use of antivirals during pregnancy.

Hepatitis B Virus in West African Children: Systematic Review and Meta-Analysis of HIV and Other Factors Associated with Hepatitis B Infection. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:4142. [PMID: 36901164 PMCID: PMC10002029 DOI: 10.3390/ijerph20054142] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Revised: 02/17/2023] [Accepted: 02/20/2023] [Indexed: 06/18/2023]
Abstract
While Hepatitis B virus (HBV) and the human immunodeficiency virus (HIV) are endemic in West Africa, the prevalence of HBV/HIV coinfection and their associated risk factors in children remains unclear. In this review, we sought to assess HBsAg seroprevalence among 0- to 16-year-olds with and without HIV in West African countries and the risk factors associated with HBV infection in this population. Research articles between 2000 and 2021 that reported the prevalence of HBV and associated risk factors in children in West Africa were retrieved from the literature using the Africa Journals Online (AJOL), PubMed, Google Scholar, and Web of Science databases as search tools. StatsDirect, a statistical software, was used to perform a meta-analysis of the retained studies. HBV prevalence and heterogeneity were then assessed with a 95% confidence interval (CI). Publication bias was evaluated using funnel plot asymmetry and Egger's test. Twenty-seven articles conducted across seven West African countries were included in this review. HBV prevalence among persons aged 0 to 16 years was 5%, based on the random analysis, given the great heterogeneity of the studies. By country, the highest prevalence was observed in Benin (10%), followed by Nigeria (7%), and Ivory Coast (5%), with Togo (1%) having the lowest. HBV prevalence in an HIV-infected population of children was (9%). Vaccinated children had lower HBV prevalence (2%) than unvaccinated children (6%). HBV prevalence with a defined risk factor such as HIV co-infection, maternal HBsAg positivity, undergoing surgery, scarification, or being unvaccinated ranged from 3-9%. The study highlights the need to reinforce vaccination of newborns, screening for HBV, and HBV prophylaxis among pregnant women in Africa, particularly in West Africa, to achieve the WHO goal of HBV elimination, particularly in children.

Characterization of Hepatitis B Virus in Tenofovir-Treated and Untreated Chronically Infected Mothers and Their Immunoprophylaxis Failure Infants. Clin Infect Dis 2023; 76:e783-e790. [PMID: 35789261 DOI: 10.1093/cid/ciac539] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Revised: 06/22/2022] [Accepted: 06/29/2022] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND Maternal tenofovir disoproxil fumarate (TDF) therapy during late pregnancy can reduce mother-to-infant transmission of hepatitis B virus (HBV). We investigated HBV mutations associated with maternal TDF therapy and their role in infant immunonophylaxis failure (IPF). METHODS Serum samples from untreated (n = 89) and TDF-treated (n = 68), highly viremic, chronically infected mothers and their infants were analyzed for HBV DNA by nested polymerase chain reaction (PCR) and direct sequencing. RESULTS At delivery, compared with untreated mothers, TDF-treated mothers had a lower HBV DNA titer and a higher frequency of basal core promoter (BCP) gene mutations, but they had similar frequencies in pre-S/S and pre-core/core mutations. The 14 mothers harboring surface "a" determinant mutants did not transmit the mutants to their immunized infants. Such mutants were found in 3 of 13 IPF infants; the 13 mothers had wild-type hepatitis B surface antigen (HBsAg). In univariable analysis, maternal HBV DNA titer (odds ratio [OR]: 1.54; 95% confidence intervals [CI]: 1.02-2.33; P = .039), genotype C (OR: 4.18; 95% CI: 1.28-13.62; P = .018) and pre-S1 wild-type sequence (OR: 6.33; 95% CI: 1.85-21.68; P = .003) at delivery were associated with infant IPF. Multivariable analyses showed that maternal genotype C (OR: 3.71; 95% CI: 1.11-12.36; P = .033) and pre-S1 wild-type (OR: 6.34; 95% CI: 1.79-22.44; P = .004) were associated with infant IPF independently of maternal viremia. CONCLUSIONS Along with high maternal HBV DNA titer at delivery, maternal genotype C and pre-S1 wild-type sequence were potential risk factors for infant IPF, although BCP mutations were not. The offspring of pregnant women harboring "a" determinant mutants as major strains seemed to be protected by immunoprophylaxis. CLINICAL TRIALS REGISTRATION NCT01312012.

Hepatol Int 2023; 17:42-51. [PMID: 36109430 DOI: 10.1007/s12072-022-10412-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2022] [Accepted: 08/13/2022] [Indexed: 02/07/2023]
Abstract
OBJECTIVE To investigate the effect of antiviral therapy and drug withdrawal on the incidence of hepatitis B after delivery in pregnant women with chronic hepatitis B virus (CHB) infection who received tenofovir disoproxil fumarate (TDF) treatment. METHODS Eligible CHB pregnant women were enrolled, and received TDF at 32 weeks gestation. The drug was stopped immediately or at 6 weeks after delivery. The HBV biomarkers and clinical biochemical parameters were monitored during gestation and 24 weeks after delivery. RESULTS There were 264 women completed the observation, including 96 untreated subjects in control group. Among 168 treated subjects, 131 cases stopped drug immediately after delivery and 37 cases delayed the drug withdrawal at 6 weeks after delivery. The incidence of postpartum hepatitis in control, immediate drug withdrawal, and delayed drug withdrawal were 28.1% (27/96), 23.7% (31/131), and 24.3% (9/37), showing no significant difference (χ2 = 0.607, p = 0.738). No factor was found to be associated with the occurrence of postpartum hepatitis. It's noteworthy that 96.3% of postpartum hepatitis in control group and 92.3% of postpartum hepatitis in immediate drug withdrawal group occurred within 12 weeks after delivery. While in delayed drug withdrawal group, the rate of postpartum hepatitis occurred within 12 weeks after delivery was 77.7%. CONCLUSION Withdrawing antiviral drug immediately or at 6 weeks after delivery did not affect the incidence of postpartum hepatitis in CHB women, but delaying drug withdrawal might delay the onset of postpartum hepatitis.

The Use of Tenofovir Disoproxil Fumarate and Tenofovir Alafenamide for Preventing Vertical Transmission of Hepatitis B. J Clin Gastroenterol 2023; 57:127-138. [PMID: 36598804 DOI: 10.1097/mcg.0000000000001785] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/05/2023]
Abstract
BACKGROUND Mother-to-child transmission (MTCT) of hepatitis B virus may occur in highly viremic mothers despite the infants receiving appropriate immunoprophylaxis. We aimed to review tenofovir disoproxil fumarate (TDF) and tenofovir alafenamide (TAF) data for preventing MTCT. METHODS AND DATA SELECTION We performed a systematic review between January 1, 2015 and December 31, 2021 on PUBMED, EMBASE, Cochrane, CNKI, and Wanfang databases. Data was extracted from randomized controlled trials or cohort studies in English or Chinese. The outcomes of interest included the efficacy and safety of TDF versus TAF or TDF/TAF versus placebo for preventing MTCT (PROSPERO registration: CRD42021256656). RESULTS Data from forty-three studies (13 randomized controlled trials, 30 nonrandomized studies) were included in the review. All infants in the studies received appropriate immunoprophylaxis. Among 3656 highly viremic mothers treated with TDF, hepatitis B virus DNA suppression to the levels <200,000 IU/mL at delivery was achieved in 34% to 100% of mothers. MTCT rates were 0 to 5% and 2 to 83% in mothers treated with TDF and in those who received no treatment, respectively. Congenital malformation rates were 0 to 2.1% in the TDF groups, which did not differ from the nontreated groups. Similar findings were reported in 4 studies that enrolled 326 mothers for maternal TAF therapy, resulting in 0% of MTCT and 0% infant malformation. All studies observed that TDF or TAF maternal therapy reduced MTCT rates significantly without safety concerns when compared with untreated groups, except for 1 RCT that failed the therapeutic endpoint. CONCLUSIONS TDF is well established for preventing MTCT in highly viremic mothers, whereas TAF may become an option as data emerges.

Abstract
OBJECTIVE To add to the limited data that exist on the selection of drugs to prevent mother-to-child transmission (MTCT) of hepatitis B virus (HBV). METHODS This is a prospective cohort study that enrolled mothers with HBV-DNA ≥2 × 105 IU/ml. All enrolled mothers received either tenofovir disoproxil fumarate (TDF) or telbivudine (LdT) to prevent HBV transmission. RESULTS A total of 270 mothers received TDF treatment and 275 mothers received LdT treatment. The predelivery decline in HBV-DNA in the TDF group was higher than the LdT group (3.92 ± 0.93 log IU/ml vs. 3.76 ± 0.94 log IU/ml, P = 0.043). In the primary analysis, the MTCT rate of the TDF group was comparable to that of the LdT group, both in the intention-to-treat analysis (1.5% [4/275] vs. 1.8% [5/273], P > 0.99) and the per-protocol analysis (0% in both groups, P > 0.99). The alanine aminotransferase elevation rates in the TDF group were lower than in the LdT group (17.3% vs. 27.4%, P = 0.005). Less anorexia and more arthralgia were observed in the LdT group than the TDF group. CONCLUSIONS TDF and LdT are both effective in preventing MTCT of HBV, but they may cause different adverse events. TDF is more effective in reducing HBV viral load and had fewer alanine aminotransferase abnormalities than LdT.
