Abstract
Prior to the Food and Drug Administration approval of ledipaspavir/sofosbuvir (Harvoni®) in 2014, the treatment of hepatitis C was interferon plus or minus ribavirin. This treatment had low cure rates for hepatitis C virus and was teratogenic and therefore avoided in pregnant patients. Vertical transmission is the most common transmission of hepatitis C in pediatric patients, whereas medical equipment that was not properly cleaned and sterilized, blood products which were not checked (historically), sharing and reusing syringes and needles, and dialysis are the most common forms of hepatitis C transmission in adults. The treatment of pregnant women with direct-acting antivirals is important because the treatment of pediatric patients cannot begin until three years of age and does not always occur prior to the symptom development of hepatitis C. This review article will include glecaprevir/pibrentasvir (Mayvret®), sofosbuvir/velpatasvir (Epclusa®), and sofosbuvir/velpatasvir plus voxilaprevir (Vosevi®). We aim to review the teratogenic risk of direct-acting antivirals as well as currently published clinical trials and ongoing research on direct-acting antiviral hepatitis C treatment in pregnancy in this publication.

Abstract
Pregnant women and the general public are both directly impacted by cirrhosis which is a chronic liver disease. It is also widely known that women who have a history of injectable drug use and cirrhosis are more prone to experience unfavorable consequences that have a negative impact on the health of both the mother and the unborn child. Higher maternal Hepatitis-C Virus (HCV) in pregnancy viral load, length of labor, use of amniocentesis or fetal scalp monitoring and protracted membrane rupture are all the risk of perinatal transmission of HCV in newborns. Globally, a large number of childbearing-age women become affected by HCV every year and vertical transmission of HCV is still a serious public health concern. Pregnancy-related immune alterations have a significant impact on the course of HCV infection throughout the third trimester and provide favorable circumstances for the spread of the virus. The exacerbation of hepatic damage during pregnancy and the postpartum period is mostly responsible for HCV-specific cell-mediated immune responses. An extensive literature search done via electronic search engine including Cochrane library databases, PubMed, Google Scholar, Science Direct and HCV in pregnancy articles were included.

Abstract
Backgroundː Intrahepatic cholestasis of pregnancy (ICP), a hepatic condition that causes severe itching in late pregnancy, is linked to nonalcoholic fatty liver disease (NAFLD) due to disrupted bile acid balance. It poses maternal risks such as preterm labor and gestational diabetes and fetal risks such as preterm birth and respiratory distress. The study examined NAFLD's impact on ICP in pregnant women, highlighting management and research implications. Methodsː This retrospective study examined pregnant women (≥18 years) with ICP, assessing fatty liver with follow-up ultrasounds. Participants were divided into ICP only and ICP with fatty liver (FL) groups, excluding heavy alcohol users and incomplete data. Maternal age, medical history, and comorbidities were evaluated alongside abdominal ultrasounds to identify FL. Resultsː In this study of 43 pregnant women, the mean maternal age was 27 years. Patients with ICP and FL had significantly higher bile acid levels than those with ICP alone. However, no significant differences were found between the two groups regarding the history of gestational diabetes mellitus (GDM), dyslipidemia, polycystic ovarian syndrome (PCOS), parity, and hypothyroidism. Among women with ICP and FL, 51.85% underwent lower segment cesarean section (LSCS), while 43.75% with ICP without FL underwent LSCS. Conclusionsː ICP with FL did not show significant adverse effects on maternal and neonatal outcomes, including mode of delivery, gestational age, maternal complications, neonatal intensive care unit (NICU) admissions, and low birth weight (LBW) with asphyxia. However, additional research is required to fully comprehend the relationship between ICP, NAFLD, and their impact on pregnancy outcomes.

Abstract
BACKGROUND Data that assess maternal and infant outcomes in hepatitis C virus (HCV)-infected mothers are limited.
AIM To investigate the frequency of complications and the associated risk factors.
METHODS We performed a cohort study to compare pregnancy and fetal outcomes of HCV-viremic mothers with those of healthy mothers. Risk factors were analyzed with logistic regression.
RESULTS Among 112 consecutive HCV antibody-positive mothers screened, we enrolled 79 viremic mothers. We randomly selected 115 healthy mothers from the birth registry as the control. Compared to healthy mothers, HCV mothers had a significantly higher frequency of anemia [2.6% (3/115) vs 19.0% (15/79), P < 0.001] during pregnancy, medical conditions that required caesarian section [27.8% (32/115) vs 48.1% (38/79), P = 0.004], and nuchal cords [9.6% (11/115) vs 34.2% (27/79), P < 0.001]. In addition, the mean neonatal weight in the HCV group was significantly lower (3278.3 ± 462.0 vs 3105.1 ± 459.4 gms; P = 0.006), and the mean head circumference was smaller (33.3 ± 0.6 vs 33.1 ± 0.7 cm; P = 0.03). In a multivariate model, HCV-infected mothers were more likely to suffer anemia [adjusted odds ratio (OR): 18.1, 95% confidence interval (CI): 4.3-76.6], require caesarian sections (adjusted OR: 2.6, 95%CI: 1.4-4.9), and have nuchal cords (adjusted OR: 5.6, 95%CI: 2.4-13.0). Their neonates were also more likely to have smaller head circumferences (adjusted OR: 2.1, 95%CI: 1.1-4.3) and lower birth weights than the average (≤ 3250 gms) with an adjusted OR of 2.2 (95%CI: 1.2-4.0). The vertical transmission rate was 1% in HCV-infected mothers.
CONCLUSION Maternal HCV infections may associate with pregnancy and obstetric complications. We demonstrated a previously unreported association between maternal HCV viremia and a smaller neonatal head circumference, suggesting fetal growth restriction.

The epidemiology and disease burden of children hospitalized for viral infections within the family Flaviviridae in China: A national cross-sectional study. PLoS Negl Trop Dis 2022; 16:e0010562. [PMID: 35788743 PMCID: PMC9286261 DOI: 10.1371/journal.pntd.0010562] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2022] [Revised: 07/15/2022] [Accepted: 06/03/2022] [Indexed: 11/24/2022] Open
Abstract
Background Viruses of the family Flaviviridae, including Japanese encephalitis virus (JEV), dengue virus (DENV), yellow fever virus (YFV) and hepatitis C virus (HCV), are widely distributed worldwide. JEV, DENV and YFV belong to the genus Flavivirus, whereas HCV belongs to the genus Hepacivirus. Children’s symptoms are usually severe. As a result, rates of hospitalization due to infection with these viruses are high. The epidemiology and disease burden of hospitalized children have rarely been described in detail to date. The objective of this study was to report the general epidemiological characteristics, clinical phenotype, length of stay (LOS), burden of disease, and potential risk factors for hospitalized children infected with JEV, DENV, YFV, or HCV in Chinese pediatric hospitals. Methodology A cross-sectional study of epidemiology and disease burden of children hospitalized for Flaviviridae virus infections between December 2015 and December 2020 in China was performed. Face sheets of discharge medical records (FSMRs) were collected from 27 tertiary children’s hospitals in the Futang Research Center of Pediatric Development and aggregated into FUTang Update medical REcords (FUTURE). Information on sociodemographic variables, clinical phenotype, and LOS as well as economic burden was included in FSMRs and compared using appropriate statistical tests. Findings The study described 490 children aged 0–15 years hospitalized for infections with Flaviviridae viruses. Japanese encephalitis (JE) cases are the highest, accounting for 92.65% of the total hospitalization cases caused by Flaviviridae virus infection. The incidence of JE peaked from July to October with a profile of a high proportion of severe cases (68.06%) and low mortality (0.44%). Rural children had a significantly higher incidence than urban children (91.63%). Most hospitalized dengue cases were reported in 2019 when dengue outbreaks occurred in many provinces of China, although only 14 dengue cases were collected during the study period. Yellow fever (YF) is still an imported disease in China. The hospitalizations for children with hepatitis C (HC) were not high, and mild chronic HC was the main clinical phenotype of patients. Among the four viral infections, JE had the highest disease burden (LOS and expenditure) for hospitalized children. Conclusion First, the present study reveals that JE remains the most serious disease due to Flaviviridae virus infection and threatens children’s health in China. Many pediatric patients have severe illnesses, but their mortality rate is lower, suggesting that existing treatment is effective. Both JEV vaccination and infection control of rural children should represent a focus of study. Second, although the dual risks of indigenous epidemics and imports of DENV still exist, the prevalence of DENV in children is generally manageable. Third, YFV currently shows no evidence of an epidemic in China. Finally, the proportion of children with chronic hepatitis C (CHC) is relatively large among hospitalized children diagnosed with HCV. Thus, early and effective intervention should be offered to children infected with HCV to ease the burden of CHC on public health. We performed a general epidemiological and disease burden assessment of 490 hospitalized children infected with any virus from the family Flaviviridae [Japanese encephalitis virus (JEV), dengue virus (DENV), yellow fever virus (YFV) and hepatitis C virus (HCV)] from December 2015 to December 2020 with confirmed clinical presentation and laboratory results. Our study found that hospitalization for Japanese encephalitis (JE) predominated in children who lived in rural areas, and the infection was rate was considerably higher in summer and autumn (July–October) compared with other months. In addition, children hospitalized with JE have the largest share of disease burden. However, the overall low rate of hospitalization and mortality of children shows that China’s JE prevention and control policies remain effective. However, the prevention, control and surveillance of JEV in rural areas should not be neglected. Dengue and yellow fever have not yet caused serious public health concerns among children in China, but the spatial and temporal distributions of viral infection must be assessed to be alert to the indigenous spread of imported cases. CHC is a refractory phenotype of HCV infection in children; thus, early screening and intervention are encouraged given the insidious appearance of symptoms in the early stages after HCV infection. These findings can help to understand the epidemic status of viruses classified in the family Flaviviridae in children and the disease burden of hospitalized children, which is conducive to precise prevention and control, optimization of the allocation of resources, and the formulation of more reasonable and effective policies.

Abstract
BACKGROUND The first guidelines for care of pregnant women carrying the hepatitis C virus (HCV) and their infants were published in 2005 in Japan. Since then, evidence has gradually accumulated worldwide regarding the natural course and treatment of this condition and, especially in recent years, treatment for chronic hepatitis C in adult patients has made great progress. However, the clinical practice policy for children has not been standardized, and new clinical practice guidelines for children with mother-to-child (MTC) transmitted HCV infection have become necessary. METHODS In the development of the current guideline, we requested cooperation from The Japanese Society for Pediatric Infectious Diseases, The Japan Society of Hepatology, and the Japan Society of Obstetrics and Gynecology. The committee members were recommended and approved by each society to participate in developing the guidelines. The guideline was also created in accordance with the Minds Guide for Practice Guideline Development. The statements were prepared by consensus-building using the Delphi method, based on the comprehensively searched academic papers and guidelines. These articles were retrieved through searching the PubMed, Cochrane Library, and the Igaku Chuo Zasshi databases. RESULTS Eight clinical questions (CQs) with clinical statements were developed regarding etiology (CQs 1-3), diagnosis (CQs 4 and 5), and treatment (two CQs 6 and 7). In each statement, the consensus rate, evidence level, and recommendation level were determined. CONCLUSION The guidelines will be helpful in the management of children with hepatitis C MTC transmission.

Abstract
Many maternal immune cells populate the decidua, which is the mucosal lining of the uterus transformed during pregnancy. Here, abundant natural killer (NK) cells and macrophages help the uterine vasculature adapt to fetal demands for gas and nutrients, thereby supporting fetal growth. Fetal trophoblast cells budding off the forming placenta and invading deep into maternal tissues come into contact with these and other immune cells. Besides their homeostatic functions, decidual NK cells can respond to pathogens during infection, but in doing so, they may become conflicted between destroying the invader and sustaining fetoplacental growth. We review how maternal NK cells balance their double duty both in the local microenvironment of the uterus and systemically, during toxoplasmosis, influenza, cytomegalovirus, malaria and other infections that threat pregnancy. We also discuss recent developments in the understanding of NK-cell responses to SARS-Cov-2 infection and the possible dangers of COVID-19 during pregnancy.

Abstract
Hepatitis C virus prevalence has steeply risen among pregnant women in association with the opioid epidemic and the major national infectious diseases and liver society guidelines recommend universal hepatitis C virus testing in pregnancy. All infants born to mothers with hepatitis C virus infection should be evaluated. Many children spontaneously clear hepatitis C virus or remain minimally symptomatic, but some develop significant liver disease if untreated. With hepatitis C virus cure available starting at age 3, we must improve programs to identify and cure hepatitis C virus-infected women and infants with the goal of eliminating mother-to-child transmission.

Abstract
Parenteral transmission is the major route of hepatitis C virus transmission in adults; however, vertical transmission is most common in children. There are several factors that have been shown to be associated with vertical transmission of hepatitis C virus, including hepatitis C virus RNA, human immunodeficiency virus coinfection, and peripheral blood mononuclear cell infection. As there is no effective vaccine to prevent hepatitis C virus infection, and there are no human data describing the safety of the new direct acting antiviral agents in pregnancy, the only preventive strategy for vertical transmission is to treat the hepatitis C virus infection before becoming pregnant. Direct acting antiviral agents are interferon-free, and many are also ribavirin-free. Based on animal studies, sofosbuvir plus ledipasvir may be the best safety profile during pregnancy for now; however, it is too early to recommend treating hepatitis C virus-infected pregnant women with these direct acting antiviral agents currently.

Abstract
Introduction hepatitis C is an infection which can be passed from mother to child. The purpose of this study was to investigate the prevalence of colonization by anti-HCV antibodies in pregnant women living in Cotonou and to identify factors associated with it. Methods we conducted a cross-sectional study of 253 pregnant women admitted for prenatal care in four major maternity hospitals in Cotonou (Benin) from 01/06/2018 to 01/09/2018. Anti-HCV antibodies were detected using rapid diagnostic tests. A venous blood sample was collected from pregnant women tested positive for anti-HCV before confirmatory serological tests and screening tests for gestational diabetes. Results the prevalence of anti-HCV antibodies was 1.2% (3/253 pregnant women). Factors associated with HCV carriage couldn't be identified given the low number of positive cases. However, pregnant women who were carriers of hepatitis C antibodies had higher mean age (32 ± 3) compared to the remainder of the population (29.58 ± 5.5). Potential risk factors for HCV infection were scarifications, piercing, tattooing, sharing of manicure equipment, a history of surgery and blood transfusions. The prevalence of gestational diabetes in our study population was 7.9% (20/253). No association was found between gestational diabetes and hepatitis C. Conclusion the prevalence of anti-HCV antibodies in pregnant women living in Cotonou was low. A national-level study is needed to identify factors associated with this infection.

Abstract
OBJECTIVES Despite the high burden of hepatitis C virus (HCV) infection in Egypt, screening of pregnant women is not yet universal, making national and global elimination unlikely. This study assessed the proportion of pregnant women who were screened for HCV infection at delivery, the prevalence and risk factors for HCV infection, the associated adverse neonatal outcomes, and the real-life linkage to care of infected women and follow-up of their infants' HCV status and timing of testing. METHODS Data were collected from medical records of a retrospective cohort of all pregnant women who were admitted to a university hospital in Cairo for delivery between January and June 2018 (n = 6734). HCV antibody- and RNA-positive women and their infants were prospectively followed-up by phone interviews till September 2019. RESULTS 2177 (32.3%) pregnant women were screened for HCV infection. 19 (0.9%) tested HCV antibody- and RNA-positive. Being ≥ 30 years old (ORa 3.6, 95% CI: 1.4-9.2; P = 0.009), history of abortion (ORa 3.5, 95% CI: 1.2-10.3; P = 0.022) and blood transfusion (ORa 29.1, 95% CI: 9.6-88.4; P < 0.001) were independent risk factors for infection. Adverse neonatal outcomes did not vary significantly among HCV antibody-positive and antibody-negative women. Only 13 (68.4%) HCV antibody- and RNA-positive women started treatment with direct-acting antivirals (DAAs) post-breastfeeding (two completed the treatment course and were cured). Four (21.1%) did not start treatment, and two (10.5%) were lost to follow-up. All infants of the 13 HCV antibody- and RNA-positive women who started DAA therapy tested HCV RNA-negative within their first year of life. CONCLUSION Extending screening services to all pregnant women and better linkage to care are essential for the national elimination of HCV infection.

Abstract
Viral hepatitis can cause significant maternal and neonatal morbidity and mortality. Hepatitis A and E mainly present as acute hepatitis during pregnancy, while hepatitis C and D are usually found as chronic infection in pregnant women. Hepatitis A remains self-limiting during pregnancy while hepatitis E has a higher prevalence and manifests with a rigorous course in pregnant women. Screening of hepatitis C during pregnancy and its subsequent management during pregnancy are still a debatable topic. New treatments of hepatitis C and E require further evaluation for use in pregnancy. This review summarizes the prevalence, clinical manifestations, maternal, foetal and neonatal effects, and the management of hepatitis A, C, D and E viral infection during pregnancy.

Abstract
Background Severe intrahepatic cholestasis of pregnancy (ICP), defined as a serum bile acid (SBA) level > 100 μmol/l, remains poorly understood in its mechanism and implications. Case A patient with a missed diagnosis of mild ICP went on to develop clinical jaundice and liver function abnormalities in the setting of newly diagnosed hepatitis C and severe ICP on repeat SBA testing. Conclusion This case highlights and adds to the growing body of evidence supporting the need for universal screening for hepatitis C in ICP patients and the potential role for repeat SBA testing, which would be a notable change from the traditional care of these individuals. Patient who presented with clinical jaundice and was diagnosed with ICP and previously undiagnosed Hepatitis C. Evaluation of hepatic synthetic function is important in patients with severe intrahepatic cholestasis of pregnancy. The case presented supports for the role of repeat serum bile acid testing in patients with Intrahepatic Cholestasis of Pregnancy.

Abstract
Infection with hepatitis C virus (HCV) is a major health problem worldwide. A large proportion of perinatal HCV infections are silent and may present later in adulthood with long-term complications. HCV has no effective immune prophylaxis and hence appropriate follow-up of all infants born to HCV-infected mothers is necessary. Universal antenatal screening for HCV is largely debatable. Intrauterine and partum transmission of HCV are both possible and higher rates are associated with a high maternal serum viral load (> 106 copies per milliliter), concomitant HIV infection, prolonged or difficult delivery, and invasive fetal monitoring during delivery. Infection during pregnancy and infancy needs to be investigated more in order to design management strategies for perinatal transmission of HCV most effectively. The recently approved new-generation, oral, direct-acting antiviral drugs may open a new era in HCV therapy for pregnant women and infected infants if proved to be safe during conception and infancy.

Abstract
BACKGROUND More than 360 million people have chronic hepatitis B or C (HBV/HCV) infection worldwide, many of which are women at childbearing age. While the risk of perinatal HBV/HCV has been well established, the long-term implications on offspring health, have been less studied. We aimed to evaluate the association between maternal HBV/HCV carrier status and long-term gastrointestinal (GI) morbidities in offspring. AIMS & METHODS A population-based cohort analysis compared the risk for long-term childhood GI morbidities in children born to HBV/HCV carrier mothers vs the risk in those who were born to noncarriers. Childhood GI morbidities were predefined based on ICD-9 codes, as recorded in hospital medical files. Children with congenital malformations and multiple gestations were excluded from the analysis. A Kaplan-Meier survival curve was constructed to compare the cumulative GI morbidities over time, and a Cox proportional hazards model was used to control for confounders. RESULTS During the study period (1991-2014), 242 342 newborns met the inclusion criteria: 771 (0.3%) were born to HBV/HCV mothers and 241 571 (99.7%) were not. The median follow-up was 10.51 years (0-18 years). Offspring to HBV/HCV mothers had a higher incidence of GI diseases (9.3% vs 5.4%, OR = 1.82; 95% CI 1.43-2.32; Kaplan-Meier log-rank = 0.001). The increased risk remained significant in the Cox proportional hazards models, which adjusted for gestational age, mode of delivery and pregnancy complications (adjusted HR = 2.26, 95% CI: 1.79-2.85; P < .001). CONCLUSION Maternal HBV or HCV carrier status is an independent risk factor for long-term the GI morbidity of offspring.

Abstract
OBJECTIVES The opioid epidemic has resulted in rising rates of hepatitis C virus (HCV) infection in women of childbearing age. With this changing epidemiology in mind, the Infectious Diseases Society of America/American Association for the Study of Liver Diseases guidelines were updated in 2018 to recommend screening all pregnant women for HCV infection, irrespective of risk factors. Because HCV infection can affect maternal-fetal health and result in vertical transmission, presentation for pregnancy-related medical care represents an opportunity to diagnose and manage HCV infection, as well as prepare for treatment postpartum. METHODS We performed a retrospective chart review spanning 2007-2016 to examine the epidemiology of HCV infection and opioid use disorder in a southern academic obstetrical clinic and to explore the impact of new screening guidelines if implemented. Composite data from the electronic health record and individual chart review were used to determine rates of HCV infection and opioid use disorder in obstetrics, explore patient demographics, and examine perinatal outcomes. RESULTS Rates of both opioid use disorder and chronic HCV infection increased significantly during the 10-year period of analysis. Patients diagnosed as having chronic HCV infection were primarily white (95%) and there was no observed impact of HCV on perinatal outcomes. HCV testing in pregnancy, even when patients had documented opioid use disorder, was infrequent (0.7% of all pregnancies). Documented follow-up for HCV postpartum for both mothers and infants was incomplete, with only one-third of identified HCV-exposed infants referred and only 9% receiving HCV testing at our institution. CONCLUSIONS HCV prevalence increased between 2007 and 2016, but screening and treatment of HCV in this southern obstetrical cohort was infrequent. The implementation of universal screening in pregnancy will likely identify additional cases, and an improved cascade of care will be necessary to address the HCV epidemic.

Abstract
BACKGROUND Hepatitis B and C are diseases with high morbimortality and constitute a global public health problem. In Brazil, the prevalence is not homogeneous, oscillating among different regions, but it is estimated that currently about 1% of the population present chronic disease related to the B virus and that there are 1.5 million infected with the C virus. Despite the development of hepatitis B vaccine, improvement in diagnostic methods and therapeutic advances in the field of viral hepatitis, there is still a large number of people who continues to be infected by these viruses, especially in populations at risk and also due to several factors, including vaccination and migration policies. Vertical and perinatal transmissions are of great importance in the epidemiology of viral hepatitis and the blood tests performed during prenatal care constitute a great opportunity for screening and identifying these viruses. OBJECTIVE To evaluate the seroprevalence of markers for B and C viruses in women who underwent prenatal care at the Hospital Universitário Antônio Pedro (Antonio Pedro University Hospital) from 2006 to 2013 and to compare the results found with regional data and those described in the specific literature. METHODS A descriptive, cross-sectional, quantitative study with retrospective data collected from 635 records of pregnant women attended at the Prenatal Service of the Hospital Universitário Antônio Pedro, Niterói, state of Rio de Janeiro, from March 2006 until December 2013. The database was built in the Microsoft Office Access program and was later exported to Microsoft Office Excel. For the processing and analysis of the data, it was used the SPSS (Statistical Package for Social Science, IBM) version 22.0, for Windows. RESULTS Twelve cases with positive HBsAg (1.9%), 189 cases with positive anti-HBs (35.9%) and seven positive anti-HCV patients (1.3%) were observed. There was no significant association between age and positivity for HBsAg, anti-HBs and anti-HCV (P =0.205, 0.872 and 0.676, respectively). There was a direct relationship between the anti-HBs positivity and the last four years of the study (P<0.0001). CONCLUSION A high prevalence of HBsAg was observed, higher than the expected for the evaluated region; there was a prevalence of anti-HCV, consistent with the current Brazilian reality; and a likely low rate of hepatitis B immunization, with a relatively high rate of susceptibility to this infection and no case of co-infection between B and C viruses and HIV. It is emphasized not only the need to trace hepatitis B and C, without exceptions, during prenatal care, since even though the current advances in therapy may not cure, at least they may allow a better quality of life for patients with chronic disease and the mandatory completion of immunoprophylaxis in all newborns. Special attention should be given to those patients susceptible to HBV, with prompt diagnosis and referral for specific vaccination.

Abstract
BACKGROUND Infection with the hepatitis C virus (HCV) during pregnancy has emerged as an increasingly recognized and prevalent condition among women of reproductive age in the United States. While screening recommendations exist for pregnant women at high risk of HCV infection, pregnant women with HCV are often under-screened, not diagnosed, or do not receive adequate follow-up, thereby increasing the risk of suboptimal maternal and infant outcomes (including in future pregnancies). CASE A pregnant woman living with HIV presented with intrahepatic cholestasis of pregnancy. She had tested negative for HCV earlier in pregnancy as part of routine screening recommended for women living with HIV. She was found to have sexually acquired a new HCV infection from her partner during pregnancy. She successfully completed treatment postpartum. CONCLUSION With the rise in HCV infection among pregnant patients, physicians should be diligent in assessing pregnant women and their partners for HCV risk factors, testing for HCV when risk is identified, and arranging follow-up testing and treatment for HCV-positive mothers and their infants.

Abstract
Chronic hepatitis C virus (HCV) infection is a leading cause of death, especially in immunocompromised patients. The lack of clear prevalence data in the Middle East makes it difficult to estimate the true morbidity and mortality burden of HCV. In Kuwait, estimating the burden of disease is complicated by the constant flow of expatriates, many of whom are from HCV-endemic areas. The development of new and revolutionary treatments for HCV necessitates the standardization of clinical practice across all healthcare institutions. While international guidelines from the American Association for the Study of Liver Diseases (AASLD) and European Association for the Study of the Liver (EASL) do address this evolving treatment landscape, the cost-driven treatment prioritization of patients by these guidelines and unique HCV genotype presentation in the Kuwaiti population prompted the development of a more tailored approach. The predominant HCV genotypes prevalent in Kuwait are genotypes 4 and 1. The Kuwait Hepatology Club (KHC), comprising hepatologists across all major institutions in Kuwait, conducted several consensus meetings to develop the scoring criteria, evaluate all current evidence, and propose screening, diagnosis, and treatment suggestions for the management of HCV in this population. While these treatment suggestions were largely consistent with the 2016 AASLD and 2015 EASL guidelines, they also addressed gaps in the unmet needs of the Kuwaiti population with HCV.

Abstract
INTRODUCTION Hepatitis C virus (HCV) infection is an important contributor to the worldwide burden of liver-related morbidity and mortality. Mother-to-child transmission of HCV ranges from 6 to 11% in different populations globally, but accurate estimates on the burden of pediatric HCV infection are limited because screening approaches are not consistent. Areas covered: The advent of new direct-acting antiviral agents that achieve very high rates of sustained virologic response (representing virologic cure) with short (i.e. 8-12 weeks) regimens has revolutionized the field of HCV treatment and led to the development of global elimination goals for HCV transmission and mortality. However, information on their safety during pregnancy and efficacy in preventing mother-to-child transmission is lacking. Currently, there are no approved treatment regimens with these antiviral agents for children younger than 12 years of age. Expert commentary: If these agents are shown to be safe during pregnancy and effective in preventing transmission to the infant, screening of pregnant women and antenatal treatment of those infected, could pave the way for eliminating pediatric HCV infection- particularly as these drugs become less costly and more accessible. Treatment of infected children when indicated, along with universal safe health care practices, can further pediatric HCV elimination.

Although screening is not recommended in the absence of certain risk factors, the importance of understanding hepatitis C in pregnancy lies in its association with adverse maternal and neonatal outcomes. There is potential for those infants infected by vertical transmission to develop chronic hepatitis C, cirrhosis or hepatocellular carcinoma. The risk of vertical transmission is increased when mothers are co-infected with Human Immunodeficiency Virus (HIV) or possess a high viral load. There is no clear data supporting that mode of delivery increases or reduces risk. Breastfeeding is not associated with increased risk of transmission. Premature rupture of membranes, invasive procedures (such as amniocentesis), intrapartum events, or fetal scalp monitoring may increase risk of transmission. In pregnant patients, hepatitis C is diagnosed with a positive ELISA-3 and detectable Hepatitis C Virus (HCV) RNA viral load. Infants born to HCV-infected mothers should be tested for either HCV RNA on at least two separate occasions. Although prevention is not possible, there may be a role for newer direct acting anti-viral medications in the future.

Abstract
Importance An estimated 1% to 2.5% of pregnant women in the United States are infected with hepatitis C virus (HCV), which carries approximately a 6% risk of mother-to-infant transmission. Objectives The aims of this article are to review the current evidence on HCV in pregnancy and to provide updated recommendations for management. Evidence Acquisition Original research articles, review articles, and guidelines on HCV in general and specifically in pregnancy were reviewed, as were drug safety profiles from the Food and Drug Administration. Results Pregnancy appears to have a beneficial effect on the course of maternal chronic HCV infection. However, it is associated with an increased risk of adverse fetal outcomes, including fetal growth restriction and low birth weight, and can be transmitted to the infant in utero or during the peripartum period. No perinatal intervention has been shown to reduce the risk of vertical transmission, but some may increase this risk. To date, no treatment regimens for HCV have been approved for use in pregnancy, but the new ribavirin-free, direct-acting antiviral regimens are being used with high efficacy outside pregnancy. Conclusions and Relevance Hepatitis C virus infection in pregnancy generally does not adversely affect maternal well-being but is associated with adverse effects on the fetus because of pregnancy complications and vertical transmission. There are currently no approved treatment regimens for HCV in pregnancy; this should be an active area of research in obstetrics.

Abstract
OBJECTIVE To assess prospectively the maternal and fetal outcome among pregnant women with chronic Hepatitis-C virus (HCV) infection compared to normal control group. METHODS A prospective observational study conducted on 342 pregnant women with HCV who were divided into two groups according to polymerase chain reaction (PCR) result, group 1 (n = 184, HCV-PCR negative) and group 2 (n = 154, HCV-PCR positive) with a third group of normal pregnant women (n = 170). Obstetric outcome was recorded. RESULTS Patients with positive HCV-PCR have more elevated liver enzymes (p < 0.05) and lower prothrombin INR (p < 0.001) than those with negative HCV-PCR testing. Fewer patients with HCV received previous medical treatment (16/342, 4.6%). More women in the HCV groups delivered by vacuum or cesarean section (p < 0.05), experienced higher rates of antepartum hemorrhage, postpartum hemorrhage, anemia, development of GDM, premature rupture of membranes, repeated hospital admissions, blood transfusions, admission to ICU and maternal mortality (p < 0.001) compared to the control group. Fetuses of women with HCV infections were more prone to IUFD with higher rates of low birth weight, prematurity, low Apgar scores at 5 min, admission to NICU, need for ventilation, and acquisition of HCV (p < 0.001) as well as neonatal mortality (p < 0.05) compared to the control group. CONCLUSION Patients with HCV infection even those without viremia suffered poor maternal and fetal outcome. Multidisciplinary management of the affected patients should be implemented to improve their obstetric outcome.

Abstract
BACKGROUND Seroprevalence of hepatitis C in Khyber Pakhtunkhwa province of Pakistan was determined by screening blood samples of expectant mothers seeking antenatal care in gynecological units of district hospitals. The rationale behind this cohort study was that the availability of free-of-cost antenatal care in district hospitals brings expectant mothers from a broader geographical range in each district and thus provides a large sample-size of healthy pregnant women of known medical history for Hepatitis C Virus (HCV) surveillance. The study was carried out along a south west to north east transact of five districts, Kohat-Peshawar-Nowshera-Charsadda-Mardan, with the central district Peshawar and outer districts Kohat and Mardan bordering northern mountainous ranges of the Khyber Pakhtunkhwa province. This distribution of districts along the transact allowed the study to gauge the impact of proximity to remote highland communities on the HCV burden of visiting pregnant women tested for HCV infection. METHODS The cohort study randomly selected 150 pregnant women visiting each hospital for serological screening for Anti-HCV carried out by ELISA assay. The feasibility of ICT and RT-PCR assays for HCV prevalence was also examined in the present study. RESULTS With a total of 750 blood specimen screened, the results of ELISA tests revealed a staggering 5.9% frequency of Anti-HCV in the five districts with the frequency of ELISA positive cases ranging from 3.3% in Nowshera, 4.7% in Charsadda, 6.0% in Peshawar, 6.7% in Kohat, and 8.7% in Mardan. The relatively higher frequencies of Anti-HCV cases among hospital visiting pregnant women in Peshawar, Kohat and Mardan were consistent with the proximity of these hospitals to the highland communities in the bordering mountain ranges. Compared to 44 Anti-HCV positive serologic specimens detected by ELISA, only 26 and 10 blood specimens were tested positive by ICT and PCR methods, respectively. Our study validates ELISA as a reliable diagnostic technique for both acute and chronic HCV infection. CONCLUSION The HCV infection rate of 5.9% in Khyber Pakhtunkhwa province clearly exceeds the HCV prevalence rates reported for other regions in Pakistan, making this province a hotspot of HCV infection in the country.

Abstract
Extrahepatic manifestations of hepatitis C virus (HCV) infection are a rare but serious condition. This article summarizes the current literature on the association between HCV and endocrine and pulmonary manifestations, as well as idiopathic thrombocytopenic purpura (ITP). HCV may directly infect extrahepatic tissues and interact with the immune system predisposing for obstructive and interstitial lung disease, ITP, autoimmune thyroiditis, infertility, growth hormone and adrenal deficiencies, osteoporosis, and potentially lung and thyroid cancers. However, in many cases, the current evidence is divergent and cannot sufficiently confirm a true association, which emphasizes the need for future targeted projects in this field.

Abstract
PURPOSE OF REVIEW Chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections and HIV-HBV and HCV coinfection are major causes of chronic liver disease worldwide. Testing and diagnosis is the gateway for access to both treatment and prevention services, but there remains a large burden of undiagnosed infection globally. We review the global epidemiology, key challenges in the current hepatitis testing response, new tools to support the hepatitis global response (2016-2020 Global Hepatitis Health Sector strategy, and 2017 WHO guidelines on hepatitis testing) and future directions and innovations in hepatitis diagnostics. RECENT FINDINGS Key challenges in the current hepatitis testing response include lack of quality-assured serological and low-cost virological in-vitro diagnostics, limited facilities for testing, inadequate data to guide country-specific hepatitis testing approaches, stigmatization of those with or at risk of viral hepatitis and lack of guidelines on hepatitis testing for resource-limited settings. The new Global Hepatitis Health Sector strategy sets out goals for elimination of viral hepatitis as a public health threat by 2030 and gives outcome targets for reductions in new infections and mortality, as well as service delivery targets that include testing, diagnosis and treatment. The 2017 WHO hepatitis testing guidelines for adults, adolescents and children in low-income and middle-income countries outline the public health approach to strengthen and expand current testing practices for viral hepatitis and addresses who to test (testing approaches), which serological and virological assays to use (testing strategies) as well as interventions to promote linkage to prevention and care. SUMMARY Future directions and innovations in hepatitis testing include strategies to improve access such as through use of existing facility and community-based testing opportunities for hepatitis testing, near-patient or point-of-care assays for virological markers (nucleic acid testing and HCV core antigen), dried blood spot specimens used with different serological and nucleic acid test assays, multiplex and multi-disease platforms to enable testing for multiple analytes/pathogens and potential self-testing for viral hepatitis.

Abstract
BACKGROUND/OBJECTIVES Hepatitis C virus (HCV) infection is a major cause of cirrhosis worldwide. Several studies have linked HCV infection to a higher risk of developing intrahepatic cholestasis of pregnancy (ICP), but some data demonstrates contradictory results. To further investigate the association and estimated risk of ICP in patients with HCV infection, we conducted this meta-analysis to summarize all available evidence. METHODS This study consists of two meta-analyses. A literature search was performed using MEDLINE and EMBASE from inception to January 2016. The first study included observational studies that reported relative risks, odds ratios, or hazard ratios of the associations between HCV infection and risk of ICP. The second analysis included studies comparing the risk of later HCV infection in ICP patients with those without ICP. Pooled odds ratios (OR) and 95% confidence intervals (CI) were calculated using a random-effect, generic inverse variance method. RESULTS Three studies were included in the first analysis. The pooled OR of ICP in HCV-infected pregnant women compared to non-HCV pregnant women was 20.40 (95% CI, 9.39-44.33, I2=55%). Two studies were included in the second analysis. The pooled OR of later HCV infection among ICP patients compared to non-ICP patients was 4.08 (95% CI, 3.13-5.31, I2=0%). CONCLUSIONS Our meta-analysis demonstrates not only a higher risk of ICP among HCV-infected pregnant women but also an increased risk of later HCV infection among ICP patients. These findings suggest potential benefits of screening for hepatitis C in women with signs of ICP.

Abstract
Since the evidence regarding the association between maternal hepatitis C virus (HCV) infection and impaired intrauterine fetal growth had not been conclusive, the aim of the present study was to evaluate the risk of maternal HCV infection in association with intrauterine fetal growth restriction (IUGR) and/or low birth weight infants (LBW). We performed an extensive literature search of PubMed, MEDLINE, and EMBASE through December 1, 2015. The odds ratios (ORs) of HCV infection and IUGR/LBW were calculated and reported with 95% confidence intervals (95% CIs). Statistical analysis was performed using RevMen 5.3 and Stata 10.0. Seven studies involving 4,185,414 participants and 5094 HCV infection cases were included. Significant associations between HCV infection and IUGR (OR = 1.53, 95% CI: 1.40-1.68, fixed effect model) as well as LBW were observed (OR = 1.97, 95% CI: 1.43-2.71, random effect model). The results still indicated consistencies after adjusting for multiple risk factors which could affect fetal growth, including maternal age, parity, maternal smoking, alcohol abuse, drugs abuse, coinfected with HBV/HIV and preeclampsia. Our findings suggested that maternal HCV infection was significantly associated with an increased risk of impaired intrauterine fetal growth. In clinical practice, a closer monitoring of intrauterine fetal growth by a series of ultrasound might be necessary for HCV-infected pregnant population.

Abstract
BACKGROUND Viral hepatitis during pregnancy is associated with a high risk of maternal complications. The virus has a high risk of vertical transmission and it has been reported as the leading cause of maternal death. OBJECTIVES To study the prevalence of hepatitis B (HBV) and hepatitis C (HCV) viral infections among pregnant women in the Peshawar district of Pakistan. MATERIALS AND METHODS The cross-sectional study took place between July 2013 and April 2014. A total of 10,288 samples were collected from pregnant women living in different areas of the Peshawar district. The samples were centrifuged at a high speed in order to obtain a clear supernatant serum. All samples were screened for HBV and HCV using the immunochromatographic technique. RESULTS The overall prevalence of HBV was found to be 1.16%, although it varied throughout the study period. The highest prevalence of HBV (1.69%) was observed during January 2014. The overall prevalence of HCV infection among the pregnant women was observed to be 1.42%. The highest prevalence of HCV infection (2.22%) was found during March 2014. CONCLUSIONS The overall prevalence of HBV and HCV was 1.16% and 1.42%, respectively. The incidence of HCV infection among the pregnant women was higher than that of HBV infection.

Abstract
Hepatitis C virus (HCV) infection has been recognised as a worldwide health problem. HCV is the most common cause of cirrhosis, hepatocellular carcinoma and liver transplantation. The HCV prevalence reported in pregnant women is similar to that found among the general population and does not appear to have an adverse effect on the course of pregnancy. The vertical transmission of HCV (HCV-VT) is a major route of HCV infection in children in the developed countries (>90%). The overall rate of mother-to-child transmission and chronification is about 3%-8%; however, this rate is higher for mothers who are co-infected with the human immunodeficiency virus (15-20%). In this review, we analyse the course of HCV infection during gestation, the risk factors associated with HCV-VT, the diagnostic methods/clinical monitoring recommended and the new possibilities of treatment in the era of direct-acting antiviral agents, which are essential to guide future public health efforts appropriately.

Abstract
Clarifying these effects could show potential benefits of RSV vaccination of pregnant women. Given the illness and deaths caused by respiratory syncytial virus (RSV) infection during the first year of life, preventing infant RSV infections through maternal vaccination is intriguing. However, little is known about the extent and maternal effects of RSV infection during pregnancy. We describe 3 cases of maternal RSV infection diagnosed at a US center during winter 2014. Case-patient 1 (26 years old, week 33 of gestation) received a diagnosis of RSV infection and required mechanical ventilation. Case-patient 2 (27 years old, week 34 of gestation) received a diagnosis of infection with influenza A(H1N1) virus and RSV and required mechanical ventilation. Case-patient 3 (21 years old, week 32 of gestation) received a diagnosis of group A streptococcus pharyngitis and RSV infection and was monitored as an outpatient. Clarifying the effects of maternal RSV infection could yield valuable insights into potential maternal and fetal benefits of an effective RSV vaccination program.

Abstract
Viral hepatitis is a serious global public health problem. It is also a common cause of jaundice and gestational complications in pregnant women. Moreover, infected mothers can transmit the virus to their fetus or neonate, which may increase disease burden and decrease quality of life. To date, commercial vaccines have been developed for hepatitis A, B, and E and are available to the general population. The Advisory Committee on Immunization Practices currently accepts emergency vaccination against hepatitis A and B during pregnancy due to benefits that overweight the potential risks. While there are limited data from trials with limited numbers of samples that suggest the efficacy or safety of hepatitis B and E vaccines in pregnant women, additional data are necessary to provide evidence of vaccination during pregnancy.

The relationship between liver disease and pregnancy is of great clinical impact. Severe liver disease in pregnancy is rare; however, pregnancy-related liver disease is the most frequent cause of liver dysfunction during pregnancy and represents a severe threat to foetal and maternal survival. A rapid differential diagnosis between liver disease related or unrelated to pregnancy is required in women who present with liver dysfunction during pregnancy. This report summarizes the recommendation of an expert panel established by the Italian Association for the Study of the Liver (AISF) on the management of liver disease during pregnancy. The article provides an overview of liver disease occurring in pregnancy, an update on the key mechanisms involved in its pathogenesis, and an assessment of the available treatment options. The report contains in three sections: (1) specific liver diseases of pregnancy; (2) liver disease occurring during pregnancy; and (3) pregnancy in patients with pre-existing chronic liver disease. Each topic is discussed considering the most relevant data available in literature; the final statements are formulated according to both scientific evidence and clinical expertise of the involved physicians, and the AISF expert panel recommendations are reported.

Abstract
The worldwide prevalence of hepatitis C virus (HCV) infection in children is 0.05%-0.4% in developed countries and 2%-5% in resource-limited settings, where inadequately tested blood products or un-sterile medical injections still remain important routes of infection. After the screening of blood donors, mother-to-child transmission (MTCT) of HCV has become the leading cause of pediatric infection, at a rate of 5%. Maternal HIV co-infection is a significant risk factor for MTCT and anti-HIV therapy during pregnancy seemingly can reduce the transmission rate of both viruses. Conversely, a high maternal viral load is an important, but not preventable risk factor, because at present no anti-HCV treatment can be administered to pregnant women to block viral replication. Caution is needed in adopting obstetric procedures, such as amniocentesis or internal fetal monitoring, that can favor fetal exposure to HCV contaminated maternal blood, though evidence is lacking on the real risk of single obstetric practices. Mode of delivery and type of feeding do not represent significant risk factors for MTCT. Therefore, there is no reason to offer elective caesarean section or discourage breast-feeding to HCV infected parturients. Information on the natural history of vertical HCV infection is limited. The primary infection is asymptomatic in infants. At least one quarter of infected children shows a spontaneous viral clearance (SVC) that usually occurs within 6 years of life. IL-28B polymorphims and genotype 3 infection have been associated with greater chances of SVC. In general, HCV progression is mild or moderate in children with chronic infection who grow regularly, though cases with marked liver fibrosis or hepatic failure have been described. Non-organ specific autoantibodies and cryoglobulins are frequently found in children with chronic infection, but autoimmune diseases or HCV associated extrahepatic manifestations are rare.

Abstract
Pregnancy is a para-physiologic condition, which usually evolves without any complications in the majority of women, even if in some circumstances moderate or severe clinical problems can also occur. Among complications occurring during the second and the third trimester very important are those considered as concurrent to pregnancy such as hyperemesis gravidarum, intrahepatic cholestasis of pregnancy, HELLP syndrome and acute fatty liver of pregnancy. The liver diseases concurrent to pregnancy typically occur at specific times during the gestation and they may lead to significant maternal and foetal morbidity and mortality. Commonly, delivery of the foetus, even preterm, usually terminates the progression of these disorders. All chronic liver diseases, such as chronic viral hepatitis, autoimmune hepatitis, Wilson's disease, and cirrhosis of different aetiologies may cause liver damage, independently from pregnancy. In this review we will also comment the clinical implications of pregnancies occurring in women who received a orthotopic liver transplantation (OLT) Therefore, the management of immunosuppressive therapy before and after the delivery in women who received liver transplant is becoming a relevant clinical issue. Finally, we will focus on acute and chronic viral hepatitis occurring during pregnancy, on management of advanced liver disease and we will review the literature on the challenging issue regarding pregnancy and OLT.

Abstract
Hepatitis C virus (HCV) is the most common blood-borne pathogen in the United States and is a leading cause of cirrhosis, need for liver transplantation, and liver-related mortality in women. Women should be offered testing if they fall in a high-risk group for exposure. Compared to men, women have higher rates of spontaneous HCV clearance after exposure and slower progression to cirrhosis but are more susceptible to liver damage from comorbid alcohol use. Premenopausal women with HCV should be counseled about the risks of antiviral treatment during pregnancy and the potential for vertical transmission of HCV to their offspring.

Abstract
Hepatitis C virus (HCV) affects about 3% of the world’s population and peaks in subjects aged over 40 years. Its prevalence in pregnant women is low (1%-2%) in most western countries but drastically increases in women in developing countries or with high risk behaviors for blood-transmitted infections. Here we review clinical, prognostic and therapeutic aspects of HCV infection in pregnant women and their offspring infected through vertical transmission. Pregnancy-related immune weakness does not seem to affect the course of acute hepatitis C but can affect the progression of chronic hepatitis C. In fact, postpartum immune restoration can exacerbate hepatic inflammation, thereby worsening the liver disease, particularly in patients with liver cirrhosis. HCV infection increases the risk of gestational diabetes in patients with excessive weight gain, premature rupture of membrane and caesarean delivery. Only 3%-5% of infants born to HCV-positive mothers have been infected by intrauterine or perinatal transmission. Maternal viral load, human immunodeficiency virus coinfection, prolonged rupture of membranes, fetal exposure to maternal infected blood consequent to vaginal or perineal lacerations and invasive monitoring of fetus increase the risk of viral transmission. Cesarean delivery and breastfeeding increases the transmission risk in HCV/human immunodeficiency virus coinfected women. The consensus is not to offer antiviral therapy to HCV-infected pregnant women because it is based on ribavirin (pregnancy category X) because of its embryocidal and teratogenic effects in animal species. In vertically infected children, chronic C hepatitis is often associated with minimal or mild liver disease and progression to liver cirrhosis and hepatocarcinoma is lower than in adults. Infected children may be treated after the second year of life, given the adverse effects of current antiviral agents.

Abstract
About 240 million people worldwide are chronically infected with hepatitis B virus (HBV). Vertical transmission is the most important mechanism of infection persistence in endemic areas. About 150 million people worldwide are chronically infected with hepatitis C virus (HCV). Mother-to-child transmission of HCV, which occurs in 3-10% of cases, is the leading route of infection in childhood. This review focuses on strategies to reduce the vertical transmission of HBV and HCV. The at-birth prophylaxis of newborns of HBV-infected mothers with specific immunoglobulin and vaccine plus administration of antivirals (tenofovir or telbivudine) in the third trimester of pregnancy (in case of high maternal viral load) greatly reduces the risk of transmission. In contrast, currently there is no drug able to reduce the vertical transmission of HCV infection. We discuss the possibility of reducing mother-to-child HCV transmission using newly available antivirals or antivirals in the pipeline for the treatment of hepatitis C.

Abstract
Pregnant women are particularly susceptible to a number of infectious diseases, such as influenza, hepatitis E, malaria, and tuberculosis. The management of many other infections-including urinary tract infections, human immunodeficiency virus, and sexually transmitted diseases-is also made more complex by pregnancy; even if some infections do not pose a great risk to the expectant mother, they can impact fetal and neonatal development, thus posing a treatment challenge to physicians. By focusing on the most important diseases that physicians may encounter in pregnant patients, this review outlines the challenges associated with managing important infectious diseases in the pregnant population and references the most recent evidence and international treatment guidelines.
