Abstract
STUDY QUESTION What is the impact of male hepatitis B virus (HBV) infection on sperm quality, embryonic development, and assisted reproductive outcomes? SUMMARY ANSWER Male HBV infection did not affect assisted reproductive outcomes, but HBV is capable of impairing human sperm and embryo formation in the early stages following fertilization. WHAT IS KNOWN ALREADY HBV is found in germ cells and early embryos of patients with HBV. HBV may impair human sperm function via increasing reactive oxygen species. STUDY DESIGN, SIZE, DURATION We conducted a retrospective cohort study of 1581 infertile couples, including 496 male patients clinically confirmed to have hepatitis B infection, and a laboratory study of effects of HBV proteins on early embryos, using human embryonic stem cells (hESCs), human sperm, and golden hamster oocytes. PARTICIPANTS/MATERIALS, SETTING, METHODS In total, 1581 infertile couples (24-40 years of age) who were admitted to a reproductive medicine center to undergo ART for the first time from January 2019 to November 2021 were selected as the study subjects. The case group was composed of 469 couples with hepatitis B surface antigen (HBsAg)-seropositive men and seronegative women (368 for IVF and 101 for ICSI treatment). The negative control group was composed of 1112 couples where both men and women were seronegative for hepatitis B antigen. We divided these couples into three comparison groups (IVF/ICSI, IVF, and ICSI). IVF of human sperm and hamster oocytes was used to evaluate the influence of the HBV HBs protein on formation of 2-cell embryos. Mitochondrial membrane potential (MMP) of hESCs was assayed via a fluorescence intensity system. Immunofluorescence staining of the phosphorylated histone H2A.X was applied to identify DNA damage to hESCs caused by the HBV X (HBx) protein. MAIN RESULTS AND THE ROLE OF CHANCE Sperm concentration, total sperm number, and sperm with normal morphology were decreased in the couples with HBV-infected males in couples who were undergoing IVF/ICSI (male HBV(+) vs control: 469 vs 1112 individuals; sperm number, P < 0.01; normal sperm morphology, P < 0.01), IVF (368 vs 792; sperm number, P < 0.01; normal sperm morphology, P ≤ 0.05), and ICSI (101 vs 306; sperm number, P < 0.01; normal sperm morphology, P < 0.001). There was no significant difference in the number of embryo cleavages, blastocyst formation, biochemical pregnancy rate, clinical pregnancy rate, and live-birth rate between case and control groups. The 2PN fertilization rate in IVF/ICSI (P < 0.01) and ICSI (P < 0.05) couples, and the number of 2PN-fertilized oocytes in IVF (P < 0.001) couples were lower in couples with male HBV infection compared to control couples. HBV HBs protein reduced the MMP of human sperm and decreased 2-cell embryo formation in IVF of human sperm and zona-free-hamster oocyte. A reduction in fluorescence intensity and immunofluorescence staining of phosphorylated histone H2A.X indicated that HBx caused MMP impairment and DNA damage in human early embryonic cells, respectively. LARGE SCALE DATA N/A. LIMITATIONS, REASONS FOR CAUTION HBV can be examined in samples of sperm or discarded IVF early embryos from HBsAg-seropositive men and seronegative women. The hESC model in vitro may not fully mimic the natural embryos in vivo. WIDER IMPLICATIONS OF THE FINDINGS This study furthers our understanding of the influence of male HBV infection on embryonic development. Our results suggest that a semen-washing process may be necessary for male patients with HBV undergoing ART to minimize the potential negative effects of HBV infection on the early embryo.

Maternal Preconception Hepatitis B Virus Infection and Risk of Congenital Heart Diseases in Offspring Among Chinese Women Aged 20 to 49 Years. JAMA Pediatr 2023; 177:498-505. [PMID: 36912830 PMCID: PMC10012042 DOI: 10.1001/jamapediatrics.2023.0053] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Accepted: 01/12/2023] [Indexed: 03/14/2023]
Abstract
Importance Maternal hepatitis B virus (HBV) infection during early pregnancy has been related to congenital heart diseases (CHDs) in offspring. However, no study to date has evaluated the association of maternal preconception HBV infection with CHDs in offspring. Objective To explore the association of maternal preconception HBV infection with CHDs in offspring. Design, Setting, and Participants This retrospective cohort study used nearest-neighbor (1:4) propensity score matching of 2013 to 2019 data from the National Free Preconception Checkup Project (NFPCP), a national free health service for childbearing-aged women who plan to conceive throughout mainland China. Women aged 20 to 49 years who got pregnant within 1 year after preconception examination were included, and those with multiple births were excluded. Data were analyzed from September to December 2022. Exposures Maternal preconception HBV infection statuses, including uninfected, previous, and new infection. Main Outcomes and Measures The main outcome was CHDs, which were prospectively collected from the birth defect registration card of the NFPCP. Logistic regression with robust error variances was used to estimate the association between maternal preconception HBV infection status and CHD risk in offspring, after adjusting for confounding variables. Results After matching with a 1:4 ratio, there were 3 690 427 participants included in the final analysis, where 738 945 women were infected with HBV, including 393 332 women with previous infection and 345 613 women with new infection. Approximately 0.03% (800 of 2 951 482) of women uninfected with HBV preconception and women newly infected with HBV carried an infant with CHDs, whereas 0.04% (141 of 393 332) of women with HBV infection prior to pregnancy carried an infant with CHDs. After multivariable adjustment, women with HBV infection prior to pregnancy had a higher risk of CHDs in offspring compared with women who were uninfected (adjusted relative risk ratio [aRR], 1.23; 95% CI, 1.02-1.49). Moreover, compared with couples who were uninfected with HBV prior to pregnancy (680 of 2 610 968 [0.026%]), previously infected women with uninfected men (93 of 252 919 [0.037%]) or previously infected men with uninfected women (43 of 95 735 [0.045%]) had a higher incidence of CHDs in offspring and were significantly associated with a higher risk of CHDs in offspring (previously infected women with uninfected men: aRR, 1.36; 95% CI, 1.09-1.69; previously infected men with uninfected women: aRR, 1.51; 95% CI, 1.09-2.09) with multivariable adjustment, while no significant association was observed between maternal new HBV infection and CHDs in offspring. Conclusions and Relevance In this matched retrospective cohort study, maternal preconception previous HBV infection was significantly associated with CHDs in offspring. Moreover, among women with HBV-uninfected husbands, significantly increased risk of CHDs was also observed in previously infected women prior to pregnancy. Consequently, HBV screening and getting HBV vaccination-induced immunity for couples prior to pregnancy are indispensable, and those with previous HBV infection prior to pregnancy should also be taken seriously to decrease the CHDs risk in offspring.

Abstract
Hepatitis B virus (HBV) infection is a major public health problem in the world. Approximately 296 million people are chronically infected. In endemic areas, vertical transmission is a common route of transmission. There are several strategies for the prevention of HBV vertical transmission, such as antiviral treatment during the third trimester of pregnancy and immunoprophylaxis to newborns that includes the administration of hepatitis B immune globulin (HBIG) and an HBV vaccine. Despite this, immunoprophylaxis failure can occur in up to 30% of infants born to HBeAg-positive mothers and/or with high viral load. Therefore, management and prevention of HBV vertical transmission is of paramount significance. In this article, we provided a review of the epidemiology, mechanisms of pathogenesis and risk factors of vertical transmission, as well as the strategies implemented to prevent the infection.

Impact of in vitro fertilization-embryo transfer on mother-to-infant transmission in women with chronic HBV infection. Liver Int 2022; 42:2167-2174. [PMID: 35758891 DOI: 10.1111/liv.15349] [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: 07/23/2021] [Revised: 04/15/2022] [Accepted: 06/24/2022] [Indexed: 02/13/2023]
Abstract
BACKGROUND AND AIMS In vitro fertilization-embryo transfer (IVF-ET) may increase the risk of mother-to-child transmission (MTCT) of hepatitis B virus (HBV). The purpose of this study was to investigate the impact and safety of IVF-ET on MTCT in women with chronic HBV infection (CHB). METHODS The data of 298 women who got pregnant by IVF-ET and their 375 children were collected retrospectively. Mothers were divided into the CHB group (n = 224) and the control group (HBsAg negative, n = 74). After birth, newborns were routinely vaccinated with the hepatitis B vaccine, and infants in the CHB group were injected with hepatitis B immunoglobulin within 2 h after birth. Demographic information, clinical data and laboratory test results were collected. The primary outcome measures were the MTCT rate of HBV, and the secondary outcome measures were the safety of the mother and infant. RESULTS There was no case of HBV MTCT in all 282 newborns born in the CHB group and 93 neonates born in the control group. Of the two groups, the birth weight (3056.74 ± 601.65 vs. 2926.24 ± 704.86, P = .083), length (49.22 ± 1.97 vs. 48.74 ± 3.09, P = .167), 5-min Apgar score (9.97 ± 0.21 vs. 9.90 ± 0.51, P = .212), days of pregnancy (265.70 ± 12.73 vs. 262.02 ± 17.50, P = .064) and neonatal malformation rate (0.71% vs. 0, P = 1.000) were similar. Two cases of neonatal malformation occurred in the CHB group. The incidences of pregnancy and childbirth complications were similar between the two groups. CONCLUSION IVF-ET does not increase the risk of MTCT in women with chronic HBV infection, and it is safe for mothers and infants.

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.

Front Med (Lausanne) 2021; 8:744350. [PMID: 34796185 PMCID: PMC8592897 DOI: 10.3389/fmed.2021.744350] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Accepted: 10/11/2021] [Indexed: 01/21/2023] Open
Abstract
Background: Hepatitis B virus (HBV) infection is one of the health problems and has adverse effects on public health. However, the consequences of male HBV carriers for assisted reproductive techniques (ART) remain unclear. Objective: To examine whether men with HBV would impact sperm quality and the intrauterine insemination (IUI)/ in vitro fertilization (IVF)/ intracytoplasmic sperm injection (ICSI) outcomes. Methods: We retrospectively analyzed data from 681 infertile couples for IUI/IVF/ICSI fresh cycle outcomes. Case group was 176 infertile couples with male HBV infection undergoing embryo transfer in our center (99 for IVF and 77 for ICSI) and 51 infertile couples for IUI. Negative control was 454 non-infected infertility couples, matched for female age, BMI and infertility duration (102 for IUI and 198 for IVF and 154 for ICSI). Results: Sperm viability among infertile men with HBV infection was significantly lower than control group (74.1 ± 13.7 vs. 77.0 ± 12.8, P < 0.01). Sperm motility was significantly decreased in HBV positive men in comparison to the control group (32.5 ± 14.6 vs. 35.5 ± 12.9, P < 0.05). In IVF/ICSI cycles, two groups had similar results in two pronuclear (2PN) fertilization rate, implantation rate, clinical pregnant rate and abortion rate (P > 0.05). There was also no difference in the clinical pregnant rate and abortion rate in IUI cycles (P > 0.05). Conclusion: Men with HBV infection will affect their sperm quality, but not affect the outcomes of ART.

Abstract
The management of viral hepatitis in the setting of pregnancy requires special consideration. There are five liver-specific viruses (hepatitis A, B, C, D, E), each with unique epidemiology, tendency to chronicity, risk of liver complications and response to antiviral therapies. In the setting of pregnancy, the liver health of the mother, the influence of pregnancy on the clinical course of the viral infection and the effect of the virus or liver disease on the developing infant must be considered. Although all hepatitis viruses can harm the mother and the child, the greatest risk to maternal health and subsequently the fetus is seen with acute hepatitis A virus or hepatitis E virus infection during pregnancy. By contrast, the primary risks for hepatitis B virus (HBV), hepatitis C virus (HCV) and hepatitis D virus are related to the severity of the underlying liver disease in the mother and the risk of mother-to-child transmission (MTCT) for HBV and HCV. The prevention of MTCT is key to reducing the global burden of chronic viral hepatitis, and prevention strategies must take into consideration local health-care and socioeconomic challenges. This Review presents the epidemiology of acute and chronic viral hepatitis infection in pregnancy, the effect of pregnancy on the course of viral infection and, conversely, the influence of the viral infection on maternal and infant outcomes, including MTCT.

Abstract
OBJECTIVE To assess the impact of hepatitis B virus (HBV) infection in women on in vitro fertilization (IVF) outcomes. METHODS An observational monocentric case-control cohort study conducted between 2012 and 2019 compared the outcomes of the first cycle of IVF between 64 woman infected with HBV and 128 seronegative controls. Frozen embryos transfers made within 18 months of the puncture were included. The exclusion criteria were severe infections, viral co-infection in women, any viral infection in their spouse, or lack of fresh embryo transfer. The matching was performed according to age, primary infertility or secondary, conventional or intracytoplasmic injection IVF technique and date of attempt. The main analysis focused on cumulative live births rates (LBR). RESULTS The clinical and ovarian stimulation characteristics were comparable except for a longer period of infertility in the HBV group. The LBR in the HBV group, when compared to controls, was not different after transfer of fresh (14.06 vs. 25.00% P=0.08) or frozen embryos (4.17 vs. 18.92% P=0.08), but significantly decreased in cumulative analysis (15.63 vs. 35.94% P=0.003). HBV infection was negatively associated with LBR in multivariate analysis OR=0.38 (95% CI 0.14-0.92) P<0.05. The implantation rate was lower in the HBV group versus controls, in fresh (14.89 vs. 27.72% P=0.02) and frozen (3.03 vs. 21.65% P=0.01) embryo transfers. CONCLUSION This study suggests a negative impact of HBV infection in women on the cumulative LBR after IVF.

Abstract
Few studies were conducted to assess safety and efficacy of continuous antiviral therapy administrated from preconception. In the present study, 136 eligible women with chronic HBV infection were recruited, and assigned to active chronic hepatitis B (CHB) (Group A, B or C) or chronic HBV carrier (Group D). Antiviral therapy was administrated in preconception (Group A), in early (Group B) or late pregnancy (Group C and Group D). Immunoprophylaxis was administrated to all infants. Mothers’ HBV status and ALT were assessed at delivery and 7 months postpartum. Offspring’s HBV status was examined at 7 months old. Group A women showed low HBV DNA level and normal ALT throughout pregnancy. All women at delivery had an HBV DNA level of less than 106 IU/ml, but the proportion of patients with lower HBV DNA level in Group A was higher than any of other three groups (P < 0.05). No differences in obstetrical complications were found among the four groups. None of infants who completed follow-up showed positive HBsAg at age of 7 months. Congenital malformation and infant growth indicators were similar among study cohorts. Continuous antiviral therapy from preconception to entire pregnancy is effective and safe for active CHB mothers and their infants.

Abstract
Studies of vertebrate genomes have indicated that all species contain in their chromosomes stretches of DNA with sequence similarity to viral genomes. How such 'endogenous' viral elements (EVEs) ended up in host genomes is usually explained in general terms such as 'they entered the germ line at some point during evolution'. This seems a correct statement, but is also rather imprecise. The vast number of endogenous viral sequences suggest that common routes to the 'germ line' may exist, as relying on chance alone may not easily explain the abundance of EVEs in modern mammalian genomes. An increasing number of virus types have been detected in human semen and a growing number of studies have reported on viral infections that cause male infertility or subfertility and on viral infections that threaten in vitro fertilisation practices. Thus, it is timely to survey the pathway(s) that viruses can use to gain access to the human germ line. Embryo transfer and semen quality studies in livestock form another source of relevant information because virus infection during reproduction is clearly unwanted, as is the case for the human situation. In this review, studies on viruses in the male and female reproductive tract and in the early embryo will be discussed to propose a plausible viral route to the mammalian germ line.

Abstract
The aim of this study was to evaluate the effect of virus infection on estradiol (E2) production in human ovarian granulosa cells. Polyriboinosinic polyribocytidylic acid [Poly (I: C)], a synthetic analog of viral double stranded RNA that can be recognized by Toll like receptor 3 (TLR3), was used to imitate virus infection. Granulosa cells (GCs) obtained from patients undergoing in vitro fertilization and embryo transfer (IVF-ET) were cultured in vitro and treated with Poly (I: C), FSH, or both. Concentration of E2 was assayed by electrochemiluminescence. The mRNA and protein expression of TLR3 and aromatase were determined by real-time quantitative PCR (qPCR) and Western blot, respectively. The results showed that expression of TLR3 mRNA was significantly increased after Poly (I: C) stimulation. Poly (I: C) decreased E2 synthesis in FSH-treated GCs. Poly (I: C) inhibited the expression of aromatase in FSH-treated GCs. This study demonstrated that Poly (I: C) inhibits the synthesis of estradiol by granulosa cells under the stimulation of FSH, which might contribute to disturbance of follicular development and ovulation.

Abstract
Hepatitis B virus (HBV) infection is the commonest cause of chronic hepatitis, with an estimated global prevalence of 3.5%, and which leads to significant morbidity and mortality. Mother-to-child transmission (MTCT) during pregnancy is the leading form of transmission in endemic populations, and its interruption is thus crucial as the initial step in the elimination of HBV infection, notwithstanding the availability of potent antiviral medications. The risk of MTCT is dramatically reduced by timely neonatal HBV vaccination and the administration of hepatitis B immunoglobulin after birth in high-risk infants. Maternal HBV DNA quantification during pregnancy allows the assessment of the risk of newborn immunoprophylaxis failure (IF). Maternal antiviral treatment in highly viremic women can reduce the risk of IF. However, the optimal HBV DNA cutoff level for the initiation of antiviral treatment remains to be determined.

Abstract
Chronic Hepatitis B virus (HBV) infection is endemic worldwide, and the prevalence is especially high in the Asia-Pacific regions. Despite its high prevalence, the literature regarding the impact of HBV infection on subfertility and fertility treatment remains limited and conflicting. Latest studies do not suggest any detrimental effect of HBV infection on the outcome of IVF/ICSI treatment in women having chronic HBV infection. There is evidence that HBV exists in ovarian tissue including oocyte and follicular fluid, and therefore has the potential risk of transmission to the embryo, which can explain the finding of vertical transmission despite immunoprophylaxis. Most recently, we have observed the evidence of HBV viral replication in female HBV carriers undergoing IVF/ICSI treatment. This raises the question of whether antiviral medication should be administered during ovarian stimulation in IVF/ICSI treatment cycles for women with chronic HBV infection to help reduce the chance of vertical transmission.

Abstract
Hepatitis B virus (HBV) can be found in ovarian tissues. This study compared HBV DNA levels in follicular fluid collected during oocyte retrieval with paired serum samples in HBV carriers after ovarian stimulation during IVF treatment for infertility. Sixty-four HBV carrier women referred to the Assisted Reproductive Units of two Hong Kong hospitals were recruited. At oocyte retrieval, the follicular fluid aspirated from the first follicle was collected for study. In 22 women, the first follicular fluid sample from both ovaries was similarly collected and studied. These women were also tested for liver function test and HBeAg. In 28 (43.8%) women, HBV DNA was detected in follicular fluid and the level correlated with serum levels (Spearman's correlation P < .001). There was concordant detection of HBV DNA in both ovaries, and the levels were significantly correlated (Spearman's correlation P = .029). In 40% of women with FF HBV DNA, the follicular fluid:serum ratio was >1.0, suggesting stimulation of HBV replication. These women also had significantly different liver function test results. Increased HBV replication exists in 40% of women with HBV DNA detected in follicular undergoing ovarian stimulation during IVF treatment.

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.

Abstract
Purpose To evaluate the influence of hepatitis B virus (HBV) infection in men of serodiscordant couples on the reproductive outcomes. Materials and Methods A total of 134 infertile couples were included in this retrospective single-center cohort study. Sixty-six couples had hepatitis B surface antigen (HBsAg)-seropositive men and seronegative partners, while 68 couples were controls with both seronegative men and women. Overall, 134 fresh in-vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) treatments were performed. As the main outcome measures, on the day of the fresh IVF/ICSI cycle, we assessed seminal parameters Before and after sperm preparation techniques. Two-pronuclear (2PN) fertilization, 1-2-3PN fertilization, cleavage, miscarriage, pregnancy and live birth rates were collected. Results No significant differences were found between groups in terms of oocytes retrieved, oocytes injected and embryos obtained (p=0.64, p=0.97, and p=0.40, respectively). The 2PN fertilization rate (FR) was comparable among groups (p=0.51). The 1-2-3PN FR was significantly lower in the HBsAg group than in the control group (66.6% vs. 69.7%, respectively). The clinical pregnancy per cycle, implantation, miscarriage and live birth rate were comparable between the HBsAg group and the control group. The median sperm concentration/ml and total sperm count, measured at baseline and after sperm preparation, was comparable between groups (p>0.05). There was a trend toward significant lower progressive motility (35.0% vs. 55.0%; p<0.05) in the HBsAg group at baseline and after sperm preparation (p<0.05). Conclusions HBV infected men have the same chance to became father, compared to seronegative patients.

Abstract
OBJECTIVE To determine whether assisted conception increases the risk for mother-to-child transmission of hepatitis B virus (HBV) infection compared with natural conception. DESIGN Prospective cohort study. SETTING Research laboratory. PATIENT(S) A total of 305 children, 176 born with assisted conception and 129 born with natural conception, were born to a total of 251 hepatitis B surface antigen- (HBsAg-) positive women. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) The seropositive rates of HBsAg in children at birth and HBV infection rates at 9-15 months of age. RESULT(S) Overall, 7.5% (23/305) of children were HBsAg-positive at birth. The rate of HBsAg-positive children at birth did not significantly differ between children in the assisted conception group compared with those in the natural conception group (6.3% [11/176] vs. 9.3% [12/129]). Multivariate logistic regression analysis showed that conception method is not related to the rate of HBsAg-positive children at birth. All children who were positive for HBsAg at birth and were followed up for 9-15 months became negative for HBsAg after hepatitis B immunization. CONCLUSION(S) Assisted conception does not increase the risk for mother-to-child transmission of HBV compared with natural conception.

Presence of Hepatitis B virus DNA in follicular fluid in female Hepatitis B carriers and outcome of IVF/ICSI treatment: A prospective observational study. Eur J Obstet Gynecol Reprod Biol 2019; 239:11-15. [PMID: 31158788 DOI: 10.1016/j.ejogrb.2019.05.029] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2019] [Revised: 05/20/2019] [Accepted: 05/23/2019] [Indexed: 12/25/2022]
Abstract
OBJECTIVE To determine the relationship between the presence of detectable HBV DNA in the follicular fluid in HBV carriers with IVF/ICSI treatment outcome. STUDY DESIGN A prospective observational study conducted in the Assisted Reproductive Unit, a tertiary referral centre affiliated with the Department of Obstetrics and Gynecology, The Chinese University of Hong Kong; and the Union Reproductive Medicine Centre at Union Hospital, Hong Kong. The primary outcome measure was pregnancy rate. Secondary outcome measures were the prevalence of detectable HBV DNA in the follicular fluid, implantation rate, clinical pregnancy rate, ongoing pregnancy rate and live birth rate. RESULTS HBV DNA was detected in the follicular fluid of 28 (43.8%) of the 64 women, and the mean level in this group in log10 copies/mL (±SD) was 4.36 ± 1.85. Women with detectable follicular fluid HBV DNA were younger, lighter, had longer duration of infertility, higher incidence of detectable serum HBV DNA (OR 4.592, 95% C I 2.333-9.038), and significantly wider range in the number of total fertilized, viable embryos, and blastocyst rate, but no difference in cycle characteristics, stimulation and pregnancy outcomes, although the almost doubled ongoing pregnancy/live birth rate per cycle initiated (60.7% versus 38.9%) failed to reach statistical significance due to the small numbers. CONCLUSION Our results suggested HBV infection did not appear to be detrimental to the outcome of IVF/ICSI treatment.

Abstract
PURPOSE This study aimed to determine the effect of paternal hepatitis B virus (HBV) infection on reproductive outcomes of couples undergoing frozen-thawed embryo transfer (FET). METHODS This retrospective cohort study included FET cycles performed between January 2014 and March 2017 in couples with a hepatitis B surface antigen (HBsAg)-positive male partner and an HBsAg-negative female partner, which was categorized as HBsAg group. The FET cycles underwent by couples with both HBsAg-negative partners were randomly selected as controls. The primary outcome was clinical pregnancy. RESULTS A total of 117 FET cycles, comprising 39 in the HBsAg group and 78 in the control group, were included. Couples with HBsAg-positive male partners had significantly lower clinical pregnancy rate (17.9 vs 41.0%, P = 0.013), lower implantation rate (11.1 vs 24.5%, P = 0.014), and lower live birth rate (12.8 vs 30.8%, P = 0.034) compared with the control group. Moreover, the multivariate logistic regression analysis showed that paternal HBV infection was negatively associated with clinical pregnancy (odds ratio = 0.297, 95% confidence interval 0.108-0.817, P = 0.019). The miscarriage rate was not significantly different between the two groups (28.6 vs 25.0%, P = 1.000). CONCLUSIONS Paternal HBV infection resulted in a lower frequency of clinical pregnancy after FET, a difference that was probably attributed to a detrimental effect of HBV on the ability of embryos to survive freezing and thawing.

Abstract
Hepatitis B virus (HBV) can invade the male germline, and sperm-introduced HBV genes could be transcribed in embryo. This study was to explore whether viral gene transcription is regulated by host genes. Embryos were produced by in vitro fertilization of hamster oocytes with human sperm containing the HBV genome. Total RNA extracted from test and control embryos were subjected to SMART-PCR, SSH, microarray hybridization, sequencing and BLAST analysis. Twenty-nine sequences showing significant identity to five human gene families were identified, with CSH2, EIF4G2, PCBD2, PSG4 and TTN selected to represent target genes. Using qRT-PCR, when CSH2 and PCBD2 (or EIF4G2, PSG4 and TTN) were silenced by RNAi, transcriptional levels of HBV s and x genes decreased (or increased). This is the first report that host genes participate in regulation of sperm-introduced HBV gene transcription in embryo, which is critical to prevent negative impact of HBV infection on early embryonic development.

Abstract
Viral infections of the ovary may perturb ovarian functions. However, the mechanisms underlying innate immune responses in the ovary are poorly understood. The present study demonstrates that cytosolic viral DNA sensor signaling initiates the innate immune response in mouse ovarian granulosa cells and affects endocrine function. The cytosolic DNA sensors p204 and cGAS and their common signaling adaptor stimulator of interferon (IFN) genes (STING) were constitutively expressed in granulosa cells. Transfection with VACV70, a synthetic vaccinia virus (VACV) DNA analog, induced the expression of type I interferons (IFNA/B) and major inflammatory cytokines (TNFA and IL6) through IRF3 and NF-κB activation respectively. Moreover, several IFN-inducible antiviral proteins, including 2',5'-oligoadenylate synthetase, IFN-stimulating gene 15 and Mx GTPase 1, were also induced by VACV70 transfection. The innate immune responses in granulosa cells were significantly reduced by the transfection of specific small-interfering RNAs targeting p204, cGas or Sting Notably, the VACV70-triggered innate immune responses affected steroidogenesis in vivo and in vitro The data presented in this study describe the mechanism underlying ovarian immune responses to viral infection.

Abstract
AIM This study was undertaken to investigate relationship between hepatitis B virus (HBV) CpG methylation and HBV gene transcription in sperm and sperm-derived embryos. METHODS HBV-infected patient sperm and HBV plasmid-transfected donor sperm were subjected to interspecific in vitro fertilization, methylation-specific PCR, bisulfite sequencing PCR, reverse transcription PCR and real-time quantitative PCR. RESULTS Positive methylation bands for CpG islands II and III in the HBV genome were observed in patient sperm but not in controls, and methylation percentages of CpG sites varied among different patient sperm samples. After fertilization, CpG sites were highly demethylated in embryos. Transcriptional levels of HBV X and S genes increased with decrease in CpG site methylation percentages. CONCLUSION HBV CpG sites can be methylated in patient sperm before maturation. Methylation of CpG islands II and III participates in transcriptional regulation of HBV X and S genes, respectively, in sperm and sperm-derived embryos.

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

Abstract
PURPOSE This study examined the relationship between the mechanism of hepatitis B virus (HBV) father-infant transmission via reproductive cells and pregnancy outcome. METHODS Abandoned in vitro fertilization (IVF) embryos of fathers with chronic HBV infection were taken as study objects. HBV mRNA in embryos was detected, and successfully transplanted embryos were followed up to determine the relationship between HBV-infected embryos and pregnancy outcome. RESULTS HBV mRNA signals were detected in one embryo in the group with HBV-positive fathers; the positive rate was 1/18 (5.5%). IVF embryos of HBV-positive fathers with HBV mRNA signals were successfully implanted, but early abortion occurred. CONCLUSIONS HBV mRNA was found in abandoned IVF embryos of HBV-infected fathers, which confirmed that HBV could not only enter early cleavage embryos via sperm but also replicate in embryos, resulting in HBV father-infant transmission. HBV may interfere with embryonic development and thus affect pregnancy outcome.

Abstract
OBJECTIVE To investigate the vertical transmission of hepatitis B virus (HBV) via embryos to children and whether HBV in embryos has an effect on the development of the fetus and pregnancy outcomes of in vitro fertilization and embryo transfer (IVF-ET). DESIGN Long-term follow-up study. SETTING Research laboratory. PATIENT(S) Thirty-one couples with a hepatitis B surface antigen (HBsAg)-negative woman and HBsAg-positive man, and 41 couples with a HBsAg-positive woman and HBsAg-negative man, whose unfertilized oocytes and nonviable embryos were tested for HBV DNA, RNA, or HBsAg. INTERVENTION(S) HBV DNA, RNA, or HBsAg analyses in unfertilized oocytes and nonviable embryos. MAIN OUTCOME MEASURE(S) HBV serologic markers analyses. RESULT(S) We obtained follow-up data for 71 couples. A total of 24 babies were born, and no newborns exhibited defects at birth. Twelve babies were born to couples with HBV-positive oocytes and/or embryos. The pregnancy outcomes were not associated with the presence of HBV in oocytes and embryos. Three patterns of HBV serologic markers were screened. Twenty babies were anti-HBs-positive. Three babies were negative for HBsAg, antibody to hepatitis B surface antigen (anti-HBs), antibody to hepatitis B core antigen (anti-HBc), HBeAg, and antibody to hepatitis B e antigen (anti-HBe). One baby was seropositive for anti-HBs, anti-HBc, and anti-HBe at 6 months of age but seroconverted from anti-HBe-positive to anti-HBe-negative at 9 months of age. CONCLUSION(S) The presence of HBsAg in oocytes and embryos may not result in the vertical transmission of HBV in the offspring of HBV carriers.

Abstract
Hepatitis B virus (HBV) infection, the most common form of chronic hepatitis worldwide, is a major public health problem affecting an estimated 360 million people globally. Mother-to-child transmission (MTCT) is responsible for more than one third of chronic HBV infections worldwide. An estimated 15%-40% of persons chronically infected develop HBV-related complications, such as cirrhosis and hepatic carcinoma, and 25% die from these complications. MTCT can occur during pregnancy or during delivery. Screening pregnant women for HBV infection, providing infant postexposure prophylaxis, and maternal treatment with antiviral medications are strategies for reducing MTCT transmission rates and the global burden of new chronic HBV infections. Administration of hepatitis B immune globulin (HBIG) and hepatitis B (HepB) vaccine within 24 hours of birth, followed by completion of the vaccine series, is 85%-95% efficacious for prevention of MTCT. Despite timely post-exposure prophylaxis, MTCT occurs in 5%-15% of infants. Hepatitis B surface antigen (HBsAg) positive, hepatitis e antigen (HBeAg) positive mothers with HBV DNA level ≥10(6) copies/mL (>200 000 IU/mL) are at greatest risk of transmitting HBV to their infants. Consensus recommendations and evidence-based guidelines for management of chronic HBV infection and screening of pregnant women have been developed. The safety and efficacy of antiviral drug use during pregnancy are areas of ongoing research. Substantial advances have been achieved globally in reducing MTCT, but MTCT remains an ongoing health problem. Attaining a better understanding of the mechanisms of MTCT, implementing existing policies on maternal screening and infant follow-up, and addressing research gaps are critical for further reductions in MTCT transmission.

Abstract
Viral infection may perturb ovarian functions. However, innate antiviral response in the ovary has not been intensively investigated. In this study, we examined the innate antiviral system in the mouse ovary and the impacts of antiviral response on steroidogenesis. Major virus sensors, including Toll-like receptor 3 (TLR3), retinoic acid-inducible gene I, and melanoma differentiation-associated gene 5, are predominantly expressed in ovarian stromal and granulosa cells. Polyinosinic-polycytidylic acid (poly [I:C]) is a common agonist of TLR3, retinoic acid-inducible gene I, and melanoma differentiation-associated gene 5. Intraperitoneal injection of poly (I:C) activated nuclear factor kappa B and interferon (IFN) regulatory factor 3 in the ovarian cells and induced the expression of proinflammatory cytokines, including tumor necrosis factor alpha, interleukin 6, and type 1 IFNs (IFNA/B). Moreover, poly (I:C) upregulated the expression of several antiviral proteins, including 2'-5'-oligoadenylate synthetase, IFN-stimulated gene 15, and Mx GTPase 1. The innate antiviral response in the ovary was significantly reduced in Tlr3-deficient mice. Notably, we demonstrated that poly (I:C) injection inhibits steroidogenesis enzyme expression and decreases plasma estradiol and testosterone levels. The results show that the mouse ovary is equipped with innate antiviral state, and the antiviral response perturbs ovarian endocrine function.

Abstract
OBJECTIVE HBV vertical transmission is the main reason for chronic HBV infection, but there is no clear conclusion about the effect of HBV infection on pregnancy outcome. This study aimed to investigate the effect of HBV-infected embryos on pregnancy outcome. STUDY DESIGN 75 couples who received ART treatment were followed up. Among them were 25 couples (group A) with at least the husband or wife infected with HBV, and 50 couples (group B) with negative serum HBV markers of both husband and wife. The clinical pregnancy rate, early abortion rate, neonatal malformation rate, neonatal HBV infection rate, and HBV infection rate of the six-month-old infant were compared between these two groups, and Fisher's exact test was applied. HBV mRNA in abandoned embryos of the patients was detected by single-cell RT-PCR. RESULTS Both the early abortion rate and the abortion rate with the mother infected HBV in group A were significantly higher than in group B (P=0.043, P=0.030 respectively). The clinical pregnancy rates of groups A and B were 36% and 44% respectively (P=0.248>0.05). The neonatal malformation rate, neonatal HBV infection rate, and HBV infection rate of six-month-old infants in group A and group B were all 0. Specific HBV mRNA fragments were detected in 6 cases of 62 cleavage embryos in group A, giving a positive rate of 9.7%. The positive rates with mother infected and father infected with HBV were 13.2% (5/38) and 5.6% (1/18) respectively. CONCLUSIONS HBV infection can increase the early abortion rate of pregnancy, and the reason may be related to HBV-infected embryos.

Abstract
Viral infections of the ovary can cause pathological conditions. However, innate antiviral responses in the ovary are poorly understood. In this study, we demonstrate that Toll-like receptor 3 (TLR3), retinoic acid-inducible gene I (RIG-I) and melanoma differentiation-associated gene 5 (MDA5) are constitutively expressed in the mouse ovary and predominantly located in granulosa cells. Polyinosinic-polycytidylic acid [poly(I:C)], a common agonist of TLR3, MDA5 and RIG-I, induced innate antiviral responses in ovarian granulosa cells. Poly(I:C) up-regulated pro-inflammatory cytokines, including TNF-α and IL-6, and type I interferons (IFN-α/β). Moreover, poly(I:C) induced the expression of antiviral proteins, including 2'-5'-oligoadenylate synthetase, Mx GTPase 1 and IFN-stimulating gene 15, in granulosa cells. In contrast, P450 aromatase expression was inhibited by poly(I:C). The poly(I:C)-induced antiviral responses in TLR3 knockout (TLR3(-/-)) ovarian granulosa cells were reduced, and completely abolished by blocking of MDA5/RIG-I signaling. Further, the poly(I:C)-induced cytokine expression in TLR3(-/-) cells was reduced by knockdown of MDA5 or RIG-I. Data suggest that TLR3, MDA5 and RIG-I cooperate in mediating innate antiviral responses in granulosa cells, which may contribute to the defense of the ovary against viral infections.

Towards complete eradication of hepatitis B infection from perinatal transmission: review of the mechanisms of in utero infection and the use of antiviral treatment during pregnancy. Eur J Obstet Gynecol Reprod Biol 2013; 169:17-23. [PMID: 23465469 DOI: 10.1016/j.ejogrb.2013.02.001] [Citation(s) in RCA: 38] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2012] [Revised: 12/27/2012] [Accepted: 02/03/2013] [Indexed: 02/07/2023]
Abstract
Hepatitis B infection remains the most common form of chronic hepatitis. Mother to child transmission occurs despite immunoprophylaxis with vaccination and immunoglobulin. In utero infection is suggested to account for most of the cases with immunoprophylaxis failure. Infants who suffer from hepatitis B infection at birth have a higher risk of becoming chronic carriers and may develop liver cirrhosis or hepatocellular carcinoma in the future. Infected germ cells, transplacental infection, invasive prenatal diagnostic tests and various perinatal factors are possible factors leading to in utero infection and subsequent immunoprophylaxis failure. Hepatitis B e antigen positive status and high viral load increase the risk of immunoprophylaxis failure. Recent evidence shows promising results regarding the use of antiviral treatment in late gestation to suppress viral load, so as to decrease the risk of vertical transmission. This review discusses the possible mechanisms of in utero infection and the use of antiviral treatment during pregnancy.

Viral screening of spent culture media and liquid nitrogen samples of oocytes and embryos from hepatitis B, hepatitis C, and human immunodeficiency virus chronically infected women undergoing in vitro fertilization cycles. Fertil Steril 2011; 97:74-8. [PMID: 22035968 DOI: 10.1016/j.fertnstert.2011.10.006] [Citation(s) in RCA: 64] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2011] [Revised: 10/07/2011] [Accepted: 10/07/2011] [Indexed: 12/19/2022]
Abstract
OBJECTIVE To assess the presence of viral RNA or DNA sequences in spent culture media used after ovum pickup (OPU) or embryo culture and in liquid nitrogen (LN) used for oocyte or embryo vitrification in patients seropositive for human immunodeficiency virus (HIV), hepatitis C virus (HCV), and hepatitis B virus (HBV) undergoing IVF cycles. DESIGN Descriptive study. SETTING Private university-affiliated IVF center. PATIENT(S) Twenty-four women who underwent controlled ovarian stimulation for oocyte vitrification or IVF/ET. A total of 6, 11, and 6 patients were seropositive for HIV, HCV, and HBV, respectively, whereas 1 patient showed a coinfection with HCV and HBV. Seven patients presented positive blood viral load (HIV, n = 1; HBV, n = 1; HCV, n = 5). Sixty-three samples were analyzed: follicular fluid, n = 3; spent culture media, n = 33 (20 after OPU and 13 after embryo culture); and LN, n = 27 (14 and 10 after oocyte and embryo vitrification; and 3 LN storage tank samples). INTERVENTION(S) Ovum pickup, oocyte and/or embryo culture, and/or vitrification by the Cryotop open device. Reverse transcription-polymerase chain reaction analysis was performed for viral screening. MAIN OUTCOME MEASURE(S) Detection of viral sequences of HIV, HCV, and HVB. RESULT(S) All the samples analyzed tested negative for the detection of viral RNA or DNA sequences. CONCLUSION(S) We have not detected viral sequences after culture and vitrification of oocytes/embryos from HIV-, HBV-, and HCV-seropositive patients. These findings represent good evidence of the lack of risk of cross-contamination among seropositive patients, even using an open device for vitrification.
