Abstract
SUMMARYViral infections during pregnancy are associated with significant adverse perinatal and fetal outcomes. Pregnancy is a unique immunologic and physiologic state, which can influence control of virus replication, severity of disease, and vertical transmission. The placenta is the organ of the maternal-fetal interface and provides defense against microbial infection while supporting the semi-allogeneic fetus via tolerogenic immune responses. Some viruses, such as cytomegalovirus, Zika virus, and rubella virus, can breach these defenses, directly infecting the fetus and having long-lasting consequences. Even without direct placental infection, other viruses, including respiratory viruses like influenza viruses and severe acute respiratory syndrome coronavirus 2, still cause placental damage and inflammation. Concentrations of progesterone and estrogens rise during pregnancy and contribute to immunological adaptations, placentation, and placental development and play a pivotal role in creating a tolerogenic environment at the maternal-fetal interface. Animal models, including mice, nonhuman primates, rabbits, and guinea pigs, are instrumental for mechanistic insights into the pathogenesis of viral infections during pregnancy and identification of targetable treatments to improve health outcomes of pregnant individuals and offspring.

[PMID: 38668276 PMCID: PMC11054203 DOI: 10.3390/pathogens13040321] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 04/01/2024] [Accepted: 04/12/2024] [Indexed: 04/29/2024] Open
Abstract
BACKGROUND The rates of hepatitis C virus (HCV) infection have increased in the pregnant population. We aim to describe the age-stratified clinical outcomes and trends for inpatient pregnant women with HCV in the U.S. METHODS We utilized hospitalization data from the 2010-2020 National Inpatient Sample. Pregnancy and HCV were identified according to their ICD-9/ICD-10 codes. Demographic and clinical data including cirrhosis, mortality, preterm birth, and stillbirth were extracted. The age groups were defined as ≤18, 19-25, 26-34, and ≥35 years. RESULTS We identified 195,852 inpatient pregnant women with HCV, among whom 0.7% were ≤18, 26.7% were 19-25, 57.9% were 26-34, and 14.8% were ≥35 years of age. The hospitalization rates of pregnant women with HCV increased overall between 2010 and 2020, with the highest velocity in the 26-34 age group. The 26-34 age group had the highest HCV burden, with an age-standardized hospitalization rate of 660 per 100,000 in 2020. The rates of mortality and cirrhosis were significantly higher in the HCV cohort and increased further with age (p < 0.05). Among the HCV pregnant cohort, 151,017 (77.1%) delivered during hospitalization. Preterm births and stillbirths were significantly higher in the HCV pregnant cohort compared to the controls across multiple age groups (p < 0.05). Minority race/ethnicity was associated with increased mortality, cirrhosis, preterm birth, and stillbirth (p < 0.001). HIV co-infection, hepatitis B co-infection, and diabetes increased the odds of cirrhosis (p < 0.001). CONCLUSIONS Hospitalizations of pregnant women with HCV are escalating, and these women are at increased risk of mortality, cirrhosis, preterm birth, and stillbirth with modifying factors, exacerbating risks further.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) is a pandemic disease caused by severe acute respiratory syndrome CoV type 2 (SARS-CoV-2). COVID-19 is higher in men than women and sex hormones have immune-modulator effects during different viral infections, including SARS-CoV-2 infection. One of the essential sex hormones is progesterone (P4). AIMS This review aimed to reveal the association between P4 and Covid-19. RESULTS AND DISCUSSION The possible role of P4 in COVID-19 could be beneficial through the modulation of inflammatory signaling pathways, induction of the release of anti-inflammatory cytokines, and inhibition release of pro-inflammatory cytokines. P4 stimulates skew of naïve T cells from inflammatory Th1 toward anti-inflammatory Th2 with activation release of anti-inflammatory cytokines, and activation of regulatory T cells (Treg) with decreased interferon-gamma production that increased during SARS-CoV-2 infection. In addition, P4 is regarded as a potent antagonist of mineralocorticoid receptor (MR), it could reduce MRs that were activated by stimulated aldosterone from high AngII during SARS-CoV-2. P4 active metabolite allopregnanolone is regarded as a neurosteroid that acts as a positive modulator of γ-aminobutyric acid (GABAA ) so it may reduce neuropsychiatric manifestations and dysautonomia in COVID-19 patients. CONCLUSION Taken together, the anti-inflammatory and immunomodulatory properties of P4 may improve central and peripheral complications in COVID-19.

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

Abstract
With the advent of safe and well-tolerated direct-acting antiviral (DAA) medications for hepatitis C virus (HCV), disease eradication is on the horizon. However, as the rate of HCV infection among women of childbearing potential continues to rise due to the ongoing opioid epidemic in the United States, perinatal transmission of HCV presents an increasingly difficult barrier. Without the ability to treat HCV during pregnancy, complete eradication is unlikely. In this review, we discuss the current epidemiology of HCV in the United States, the current management strategy for HCV in pregnancy, as well as the potential for future use of DAAs in pregnancy.

Abstract
PURPOSE OF REVIEW In the context of the opioid epidemic, hepatitis C virus (HCV) infection prevalence is increasing among women of reproductive age. Pregnant people with HIV/HCV coinfection may be at increased risk of adverse pregnancy and neonatal outcomes, although research in this key population is lacking. RECENT FINDINGS Treatment with directly acting antivirals (DAAs) has transformed the clinical care for most patients with HCV. However, pregnant people were excluded from trials of these medications. A recent phase I study has shown promise with excellent safety profile for ledipasvir-sofosbuvir; demonstrating no episodes of perinatal transmission, 100% sustained virologic response, and no safety concerns. Pregnancy represents a time of maximal interaction with the healthcare system and therefore an ideal window of opportunity to cure HCV. Current observational data regarding pregnant people who are co-infected with HCV and HIV suggest poor outcomes such as increased risk of preterm birth; however, there are no prospective and well-controlled studies to fully understand the impact of HIV/HCV coinfection on pregnancy. Phase 1 studies suggest that DAAs are well-tolerated and effective during pregnancy. Only through large, prospective clinical trials will we be able to understand the interaction of HCV and HIV during pregnancy and to evaluate safety and efficacy of DAAs in this key population.

Abstract
Viral hepatitis is caused by a heterogenous group of viral agents representing a wide range of phylogenetic groups. Many viruses can involve the liver and cause liver injury but only a subset are delineated as 'hepatitis viruses' based upon their primary site of replication and tropism for hepatocytes which make up the bulk of the liver cell population. Since their discovery, beginning with the agent that caused serum hepatitis in the 1960s, the alphabetic designations have been utilized. To date, we have five hepatitis viruses, A through E, though it is postulated that others may exist. This chapter will focus on those viruses. Note that hepatitis D is included as a subset of hepatitis B, as it cannot exist without concurrent hepatitis B infection. Pregnancy has the potential to affect all aspects of these viral agents due to the unique immunologic and physiologic changes that occur during and after the gestational period. In this review, we will discuss the most common viral hepatitis and their effects during pregnancy.

Abstract
Viral hepatitis in pregnancy may be caused by many types of viruses that cause systemic infection or target hepatocytes in their pathogenesis. Because viral hepatitis during pregnancy may represent acute or chronic infection or the reactivation of a prior infection, a high clinical suspicion, medical history review, and awareness of risk factors for the acquisition of infection are important management principles. The route of infection varies widely and ranges from fecal-oral transmission for the hepatitis A and E viruses to vertical transmission for hepatitis B, blood-borne transmission for hepatitis C, and sexual transmission for the herpes simplex virus. For this reason, the exposure details about travel, food preferences, drug use, and sexual contacts are important to elicit. Although routine prenatal screening is recommended for chronic viral hepatitis caused by hepatitis B and C, most other causes of viral hepatitis in pregnancy are detected in the setting of compatible signs and symptoms (fatigue, abdominal discomfort, jaundice, scleral icterus) or incidentally noted transaminitis on routine labs. Serologic testing is helpful for diagnosis with molecular testing as indicated to guide the management of hepatitis B and C. Preventive vaccines for hepatitis A and B with established safety of use in pregnancy are recommended for women who are at risk of acquisition. Postexposure prophylaxis for hepatitis A is a single dose of immunoglobulin and vaccination can be used if immunoglobulin G is not available. Antiviral therapy with tenofovir disoproxil fumarate is recommended as prophylaxis in pregnant women with active hepatitis B and an elevated viral load (>200,000 IU/mL) during the third trimester to prevent vertical transmission. The neonate exposed to hepatitis B at birth should receive immunoglobulin G and a monovalent birth dose vaccine within 12 hours, followed by completion of the 3-dosage vaccine series. The prevalence of hepatitis C in women of reproductive age has increased in the United States, and the role of antiviral therapy during pregnancy is of great interest. Cesarean delivery is not currently recommended for the sole purpose of reducing vertical transmission risk in pregnant women with viral hepatitis. Breastfeeding is recommended in women with hepatitis A, B, and C. New and promising prevention and treatment options for hepatitis B and C are under investigation. Investigators and regulatory authorities should ensure that these clinical trials for promising antivirals and vaccines are designed to include pregnant and lactating women.

Abstract
BACKGROUND Chronic hepatitis C virus (HCV) infections are increasing among reproductive age individuals. Direct acting antivirals (DAAs) can cure HCV, but the use of DAAs is not currently recommended during pregnancy and breastfeeding. Individuals with HCV commonly have inadequate prenatal and postnatal care. OBJECTIVES The purpose of our study was to demonstrate the success of a quality improvement program to increase evaluation during pregnancy and ensuring access to DAA treatment medication during the postpartum period for individuals with chronic HCV to achieve cure 12 weeks after completing therapy. The primary outcome was documented HCV cure rate compared among individuals who received immediate treatment with DAA after delivery or after weaning or a traditional approach of referral to an infectious diseases specialist or hepatologist. The secondary outcome was the proportion of infants exposed to HCV evaluated. METHODS An interdisciplinary team developed a program to increase evaluation and HCV treatment for postpartum individuals. Individuals who received prenatal care from March 2017 to May 2021 were eligible. Individuals with chronic HCV had a laboratory evaluation before delivery, and appropriate DAAs were selected for postpartum treatment. The health system specialty pharmacy dispensed DAA prescriptions immediately after delivery to those who were not breastfeeding. Individuals who did breastfeed had the option to begin treatment after weaning. Cure was defined as a sustained viral response or undetectable HCV RNA collected 12 weeks after completing DAA treatment. RESULTS We demonstrate the success of an interdisciplinary team to ensure access to therapy for the treatment of postpartum chronic HCV. Only 3 infants (25%) with mothers referred were evaluated at our institution compared with 44% of infants (n = 10) whose mothers were treated after delivery. CONCLUSION An interdisciplinary team for HCV treatment improves access to treatment therapy with DAAs leading to the cure of chronic HCV after delivery.

Abstract
In the United States, it is estimated that 1% to 4% of pregnant women are infected with hepatitis C virus, which carries approximately a 5% risk of transmission from mother to infant. Hepatitis C virus can be transmitted to the infant in utero or during the peripartum period, and infection during pregnancy is associated with an increased risk of adverse fetal outcomes, including fetal growth restriction and low birthweight. The purpose of this document is to discuss the current evidence, provide updated recommendations regarding screening, review treatment, and address management of hepatitis C virus during pregnancy. The following are the Society for Maternal-Fetal Medicine's recommendations: (1) We suggest that third trimester assessment of fetal growth may be performed, but antenatal testing is not indicated in the setting of hepatitis C virus diagnosis alone (GRADE 2C); (2) we suggest screening for viral hepatitis in patients with a diagnosis of intrahepatic cholestasis of pregnancy at an early gestational age or with high levels of bile acids (GRADE 2C); (3) we recommend that obstetrical providers screen all pregnant patients for hepatitis C virus by testing for anti-hepatitis C virus antibodies in every pregnancy (GRADE 1B); (4) we suggest that obstetrical care providers screen hepatitis C virus-positive pregnant patients for other sexually transmitted infections (if not done previously), including human immunodeficiency virus, syphilis, gonorrhea, chlamydia, and hepatitis B virus (GRADE 2C); (5) we recommend vaccination against hepatitis A and B viruses (if not immune) for patients with hepatitis C virus (GRADE 1B); (6) we recommend that direct-acting antiviral regimens only be initiated in the setting of a clinical trial during pregnancy and that people who become pregnant while taking a direct-acting antiviral should be counseled in a shared decision-making framework about the risks and benefits of continuation (GRADE 1C); (7) we suggest that if prenatal diagnostic testing is requested, patients are counseled that data regarding the risk of vertical transmission are reassuring but limited (GRADE 2C); (8) we recommend against cesarean delivery solely for the indication of hepatitis C virus (GRADE 1B); (9) we suggest that obstetrical care providers avoid internal fetal monitors and early artificial rupture of membranes when managing labor in patients with hepatitis C virus unless necessary in the course of management (ie, when unable to trace the fetal heart rate with external monitors and the alternative is proceeding with cesarean delivery) (GRADE 2B); (10) we recommend that hepatitis C virus status not alter standard breastfeeding counseling and recommendations unless nipples are cracked or bleeding (GRADE 1A).

Abstract
Infectious hepatitis in pregnancy is clinically significant in both the acute and chronic phases. Here, we review the perinatal implications of chronic hepatitis B and C and acute hepatitis A and E. Familiarity with screening, transmission, diagnosis, and management of infectious hepatitis is of ongoing importance during obstetric care, as these diseases are endemic in much of the world. Pregnancy and interpregnancy care provide opportunities to prevent infection and transmission of hepatitis.

Abstract
Treatment of viral infections is geared toward ameliorating maternal symptoms and minimizing perinatal transmission. Multidisciplinary teams often are required to manage sequelae due to viral diseases in patients with preterm premature rupture of membranes (PPROM). although data are scarce regarding the antepartum management of common viruses in PPROM, essential principles may be extrapolated from national guidelines and studies in gravid patients. The well-established risks of prematurity are weighed against the often unclear risks of vertical transmission.

Abstract
Viral infections during pregnancy lead to a spectrum of maternal and fetal outcomes, ranging from asymptomatic disease to more critical conditions presenting with severe maternal morbidity, stillbirth, preterm birth, intrauterine growth restriction, and fetal congenital anomalies, either apparent at birth or later in life. In this article, we review the pathogenesis of several viral infections that are particularly relevant in the context of pregnancy and intrauterine inflammation. Understanding the diverse mechanisms employed by viral pathogens as well as the repertoire of immune responses induced in the mother may help to establish novel therapeutic options to attenuate changes in the maternal-fetal interface and prevent adverse pregnancy outcomes.

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
BACKGROUND Vertical transmission is the major cause of pediatric hepatitis C virus (HCV) infection. The objective of this study was to better understand HCV pathogenesis in pregnant women and provide insights into risk factors and mechanisms involved in vertical transmission. METHODS Evolutionary dynamics of HCV variant spectra and HCV-specific neutralizing antibody responses were examined using high-throughput sequencing and pseudoparticle-based assays in pregnant women monoinfected with HCV (n = 17) or coinfected with HCV and human immunodeficiency virus (HIV)-1 (n = 15). RESULTS Overall, statistically significant associations were found between HCV quasispecies diversity, selective pressure exerted on the HCV E2 envelope protein, and neutralizing activity of maternal immunoglobulins. Women with low quasispecies diversity displayed significantly higher mean aspartate aminotransferase and alanine aminotransferase levels throughout pregnancy, but this difference was restricted to monoinfected participants. Low quasispecies diversity and inefficient neutralizing activity were also significantly associated with vertical transmission, but only in the monoinfected group. CONCLUSIONS These results indicate that maternal neutralizing antibody responses play a role in the prevention of vertical HCV transmission, but not in presence of HIV-1 coinfection, and suggest that the mechanism of vertical transmission may be different between monoinfected and coinfected women. These findings could inform management strategies for the prevention of vertical HCV transmission.

Abstract
OBJECTIVE hepatitis C virus (HCV) is an increasingly important public health problem worldwide. Health care workers providing care to women of childbearing age are uniquely placed in their practices to identify a significant proportion of at-risk patients and to provide appropriate screening and counselling. The primary objective of this guideline is to provide accurate, current information to those offering reproductive care to women living with HCV. This document is also intended to raise awareness of HCV in both the medical and general populations. OPTIONS the areas of clinical practice considered in formulating this guideline are disease prevention, targeted screening of individuals at risk of contracting HCV, management of identified patients in the context of reproductive care, and the appropriate referral of patients to those with particular expertise. OUTCOMES implementation of these guidelines should facilitate identification of infected individuals. It should also result in improved physical and mental well-being for patients and their families and reduction in transmission rates. EVIDENCE the literature between 1966 and 2000, including non- English language publications, was extensively searched utilizing Medline. A multidisciplinary group consisting of experts within the fields of obstetrics and gynaecology, infectious diseases, hepatology, and public health convened in Montreal in February 2000. The working group also included a patient and a representative from the Hepatitis C Society of Canada. The level of evidence for the recommendations has been determined using the criteria described by the Canadian Task Force on Periodic Health Examination. BENEFITS, HARMS AND COSTS the public health benefits of increased identification of at-risk individuals, diagnosis, treatment, implementation of risk reduction behaviours, and reduced transmission rates, both on an individual and at the community level, are significant. However, it must be remembered that the diagnosis of a chronic disease may have far reaching effects for the individual patient and her family. RECOMMENDATIONS VALIDATION: references were collected through Medline searches and comparison made to existing current guidelines for assessment of consistency. External reviewers expert in their field were also consulted.

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

Abstract
Hepatitis C virus (HCV) infection is increasing among pregnant women, resulting in an increased prevalence of perinatal exposure and pediatric infection. While antiviral medications have been effective at preventing perinatal transmission of viral infections, such as HIV, there are currently no interventions to prevent the perinatal transmission of HCV. In this review, the epidemiology of HCV, current HCV screening recommendations during pregnancy and existing knowledge gaps for the use of directly acting antivirals (DAAs) medications in pregnancy will be discussed. To address the rapidly changing epidemiology of HCV, consideration should be given to universal screening for HCV during pregnancy and future studies should explore when directly acting antivirals should be used for maternal treatment during pregnancy to prevent perinatal transmission.

Abstract
BACKGROUND Pregnancy is a unique physiological condition with the cellular immune functions compromised at some extents to allow the mature of growing fetus. Whether pregnancy may influence the replication of hepatitis B virus (HBV) is less studied. The present study aimed to investigate the influence of pregnancy on the replication of HBV and expression of viral antigens by comparing the levels of HBV DNA and viral antigens in pregnant and non-pregnant women. METHODS A total of 727 HBsAg-positive serum samples, collected from 214 pregnant women and 513 non-pregnant women of childbearing age, were included. Based on the pregnancy status, subjects were divided into four groups: nulliparous (n = 158), pregnant (n = 214), 7-12 months postpartum (n = 170), and 2-5 years postpartum (n = 185). The levels of hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) were quantitatively measured with microparticle enzyme immunoassay. HBV DNA levels were detected by fluorescent real-time PCR. RESULTS The median ages of four groups were 25.0, 25.3, 26.2 and 29.3 years, respectively (p < 0.01). HBeAg-positive proportions were 34.2, 33.6, 35.3 and 29.2%, respectively (p = 0.624). HBV DNA levels in HBeAg-positive women were higher than those in HBeAg-negative women (7.88 vs 2.62 log IU/ml, p < 0.001). HBV DNA levels in the four groups with positive HBeAg were 7.8, 7.7, 8.0 and 8.0 log IU/ml, respectively (p = 0.057), while HBsAg titers were 4.4, 4.5, 4.6 and 4.8 log IU/ml (p = 0.086) and HBeAg titers were 3.1, 3.0, 3.1 and 3.0 log S/CO (p = 0.198). In the four groups with negative HBeAg, HBV DNA levels were 2.3, 2.6, 2.5 and 2.8 log IU/ml, respectively (p = 0.085), while HBsAg titers were 3.1, 3.3, 3.3 and 3.0 log IU/ml (p = 0.06). CONCLUSIONS Serum levels of HBV DNA and viral antigens showed no significant changes in nulliparous, pregnant, and postpartum women, regardless of the HBeAg status. The results indicate that pregnancy has little influence on the replication of HBV and the expression of viral antigens.

Abstract
The prevalence of hepatitis C in pregnancy is as high as 3.6% in large cohorts. The prevalence of hepatitis C acquired by vertical transmission is 0.2% to 0.4% in the United States and Europe. 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
In the United States, 1-2.5% of pregnant women are infected with hepatitis C virus, which carries an approximately 5% risk of transmission from mother to infant. Hepatitis C virus can be transmitted to the infant in utero or during the peripartum period, and infection during pregnancy is associated with increased risk of adverse fetal outcomes, including fetal growth restriction and low birthweight. The purpose of this document is to discuss the current evidence regarding hepatitis C virus in pregnancy and to provide recommendations on screening, treatment, and management of this disease during pregnancy. The following are Society for Maternal-Fetal Medicine recommendations: (1) We recommend that obstetric care providers screen women who are at increased risk for hepatitis C infection by testing for anti-hepatitis C virus antibodies at their first prenatal visit. If initial results are negative, hepatitis C screening should be repeated later in pregnancy in women with persistent or new risk factors for hepatitis C infection (eg, new or ongoing use of injected or intranasal illicit drugs) (GRADE 1B). (2) We recommend that obstetric care providers screen hepatitis C virus-positive pregnant women for other sexually transmitted diseases, including HIV, syphilis, gonorrhea, chlamydia, and hepatitis B virus (GRADE 1B). (3) We suggest that patients with hepatitis C virus, including pregnant women, be counseled to abstain from alcohol (Best Practice). (4) We recommend that direct-acting antiviral regimens only be used in the setting of a clinical trial or that antiviral treatment be deferred to the postpartum period as direct-acting antiviral regimens are not currently approved for use in pregnancy (GRADE 1C). (5) We suggest that if invasive prenatal diagnostic testing is requested, women be counseled that data on the risk of vertical transmission are reassuring but limited; amniocentesis is recommended over chorionic villus sampling given the lack of data on the latter (GRADE 2C). (6) We recommend against cesarean delivery solely for the indication of hepatitis C virus (GRADE 1B). (7) We recommend that obstetric care providers avoid internal fetal monitoring, prolonged rupture of membranes, and episiotomy in managing labor in hepatitis C virus-positive women (GRADE 1B). (8) We recommend that providers not discourage breast-feeding based on a positive hepatitis C virus infection status (GRADE 1A).

Abstract
Mother-to-child transmission of hepatitis C virus infection occurs in a significant minority of cases and the diagnosis, treatment and cure of hepatitis C virus infection with direct acting antivirals prior to pregnancy can eliminate this risk in almost all cases. Women with hepatitis C virus infection have increased risks of adverse events in pregnancy and poor perinatal outcomes for their children, although the contribution of hepatitis C virus per se is difficult to determine. Altering the mode of delivery does not reduce mother to child transmission of hepatitis C virus infection, although avoidance of fetal scalp electrodes and other potential high risk procedures is recommended during pregnancy and delivery. Breast feeding has not been demonstrated to be a risk for mother-to-child transmission and avoidance of breast feeding is not recommended, although breast feeding with cracked or bleeding nipples is generally avoided. Safety of the currently available hepatitis C virus antivirals in pregnancy and breastfeeding has not yet been established.

Abstract
The interferon (IFN)-λ family of type III cytokines includes the closely related interleukin (IL)-28A (IFN-λ2), IL-28B (IFN-λ3), and IL-29 (IFN-λ1). They signal through the Janus kinases (JAK)-signal transducers and activators of transcription pathway and promote an antiviral state by the induction of expression of several interferon-stimulated genes (ISGs). Contrary to type I IFNs, the effect of IFN-λ cytokines is largely limited to epithelial cells due to the restricted pattern of expression of their specific receptor. Several genome-wide association studies have established a strong correlation between polymorphism in the region of IL-28B gene (encoding for IFN-λ3) and both spontaneous and therapeutic IFN-mediated clearance of hepatitis C virus (HCV) infection, but the mechanism(s) underlying this enhanced viral clearance are not fully understood. IFN-λ3 directly inhibits HCV replication, and in vitro studies suggest that polymorphism in the IFN-λ3 and its recently identified overlapping IFN-λ4 govern the pattern of ISGs induced upon HCV infection of hepatocytes. IFN-λ can also be produced by dendritic cells, and apart from its antiviral action on hepatocytes, it can regulate the inflammatory response of monocytes/macrophages, thus acting at the interface between innate and adaptive immunity. Here, we review the current state of knowledge about the role of IFN-λ cytokines in mediating and regulating the immune response during acute and chronic HCV infections.

Abstract
Chronic hepatitis C virus (HCV) infection is characterized by exhaustion of virus-specific T-cells and stable viremia. Pregnancy is an exception. Viremia gradually climbs during gestation but sometimes declines sharply in the months following delivery. Here, we demonstrated that postpartum HCV control was associated with enhanced virus-specific T-cell immunity. Women with viral load declines of at least 1 log10 between the third trimester and 3-mo postpartum exhibited HCV-specific T-cell responses of greater breadth (P = 0.0052) and magnitude (P = 0.026) at 3-mo postpartum than women who failed to control viremia. Moreover, viral dynamics were consistent in women after consecutive pregnancies, suggesting genetic underpinnings. We therefore searched for genetic associations with human leukocyte antigen (HLA) alleles and IFN-λ3 gene (IFNL3) polymorphisms that influence HCV infection outcome. Postpartum viral control was associated with the IFNL3 rs12979860 genotype CC (P = 0.045 at 6 mo) that predicts a positive response to IFN-based therapy. Suppression of virus replication after pregnancy was also strongly influenced by the HLA class II DPB1 locus. HLA-DPB1 alleles are classified by high and low patterns of expression. Carriage of at least one high-expression HLA-DPB1 allele predicted resurgent virus-specific T-cell immunity and viral control at 3-mo postpartum (P = 0.0002). When considered together in multivariable analysis, IFNL3 and HLA-DPB1 independently affected viral control at 3- and 6-mo postpartum. Together, these findings support a model where spontaneous control of HCV such as sometimes follows pregnancy is governed by genetic polymorphisms that affect type III IFN signaling and virus-specific cellular immune responses.

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
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
Purpose
– The purpose of this paper is to provide a comprehensive overview of the current knowledge regarding chronic hepatitis C (CHC) infection, antiviral therapy, depression, and gender.
Design/methodology/approach
– CHC and its treatment options were reviewed examining their relationship with depression and gender.
Findings
– CHC is a high prevalent chronic infection worldwide, being similar in men and women. However, the infection shows many gender differences in terms of innate response, genetic variability (i.e. IL-28B), route of transmission (i.e. intravenous drug use), disease progression (i.e. fibrosis), lifetime period (i.e. pregnancy), and risk factors (i.e. HIV). Both the hepatitis C infection and antiviral treatment (especially when using the pro-inflammatory cytokine interferon α), are highly associated with depression, where female gender constitutes a risk factor. It seems that the new direct-acting antiviral combinations produce fewer neuropsychiatric side effects. In fact, the presence of depression at baseline is no longer a limitation for the initiation of antiviral treatment. Antidepressant drugs have been recommended as current depression and prophylactic treatment in risk subgroups. However, caution should be exercised due to the risk of drug-drug interactions with some antiviral drugs. Women should be counselled prenatal, during and after pregnancy, taking into account the clinical situation, and the available evidence of the risks and benefits of antiviral and antidepressant treatments. Multidisciplinary approach shows cost-efficacy results.
Originality/value
– The paper clarifies the complex management of CHC therapy and the importance of individualizing treatment. The results also underline the need for an integrated multidisciplinary approach.

Abstract
BACKGROUND Unique immunological changes occur during pregnancy; the impact of which, on virological and biochemical markers of hepatitis B infection is not well established. Rapid changes in the immunological profile post partum and consequent rebound of the inflammatory response may result in hepatic flares. METHODS Women with chronic hepatitis B were recruited during pregnancy into this observational study. Demographic and clinical data were collected together with virological and biochemical parameters at two time points during pregnancy (early and late) and two time points post partum (between 6 weeks and 12 weeks and at 12 months). Outcomes analysed included changes in HBV DNA, hepatitis B e antigen (HBeAg) status and flares of hepatitis. RESULTS One hundred and twenty-six women were recruited. Twenty-seven women out of 108 with postpartum bloods (25%) met our definition of a postpartum flare (ALT range 38-1654). Using univariate analysis HBeAg status, younger age, gravida and parity were associated with a flare. On multivariate analysis HBeAg positivity at baseline fell just outside of statistical significance in predicting a postpartum flare (p=0.051). CONCLUSIONS 25% of women with chronic hepatitis B will demonstrate increased liver inflammation in the postpartum period. This is usually asymptomatic and resolves spontaneously. This is more likely if the woman is HBeAg-positive at baseline (2.56 times the risk), although flares also commonly occur in HBeAg-negative women.

Abstract
Whether pregnancy may influence the replication of hepatitis B virus (HBV) remains unknown. The authors aimed to clarify this issue by observing the kinetics of HBV deoxyribonucleic acid (DNA) and viral antigens in women during and after pregnancy. Total, 371 pregnant women with positive hepatitis B surface antigen (HBsAg) were enrolled. Serial sera collected during and after pregnancy were quantitatively measured for HBV DNA, HBsAg, and hepatitis B e antigen (HBeAg). Total, 34 HBeAg-positive women underwent alanine aminotransferase (ALT) elevation during or after pregnancy; levels of HBV DNA and HBsAg in them showed no obvious change between second trimester or delivery and 7 to 12 months postpartum (P > 0.05). The 337 others had normal alanine aminotransferase levels during pregnancy and postpartum. In 147 HBeAg-positive women with follow-up 7 to 12 months postpartum, the average levels of HBV DNA (>7.0 log10 IU/mL), HBsAg (>4.0 log10 IU/mL), and HBeAg (>3.0 log10 S/CO) were longitudinally constant during pregnancy and postpartum, respectively. In 173 women with follow-up 4.8 years postpartum, neither HBV DNA levels nor antigen titers showed significant difference between second trimester and 4.8 years postpartum, regardless of the HBeAg status. In addition, levels of HBV DNA and viral antigens in second trimester, around delivery, 6 to 8 weeks and 7 to 12 months postpartum showed no marked fluctuations, respectively. Serum levels of HBV DNA and viral antigens in HBsAg-positive women are highly constant during pregnancy and postpartum, regardless of the HBeAg status and alanine aminotransferase levels. This demonstrates that pregnancy has little influence on the HBV replication and antigen expression.

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
OBJECTIVES (1) To describe obstetrical and neonatal outcomes among a cohort of hepatitis C virus (HCV) infected women, comparing HCV RNA positive to HCV RNA negative women; (2) to characterize virologic and hepatic parameters associated with HCV infection during pregnancy; and (3) to describe the rate of HCV vertical transmission. METHODS We prospectively enrolled 145 HCV-positive pregnant women across British Columbia between 2000 and 2003. Participating women were monitored during pregnancy and their infants were followed to assess them for HCV infection. Maternal HCV RNA was assessed close to delivery. RESULTS Seventy percent of women reported injection drug use as their primary risk factor for HCV acquisition. Observed rates of intrauterine fetal death, preterm delivery, small for gestational age, and low birth weight infants were 3.4%, 17.9%, 11.3%, and 12.5%, respectively, without a significant association with maternal HCV RNA status. The rate of cholestasis was 5.6% in the HCV RNA-positive group (6/108) and 2.8% in the HCV RNA-negative group (1/37) (P = 0.496). Serum alanine aminotransferase levels decreased significantly through pregnancy, and were significantly higher in HCV RNA-positive women than in HCV RNA-negative women after controlling for cholestasis, co-infections, and alcohol consumption. Among the HCV RNA-positive women, the median FIB-4 score was 0.67 (IQR 0.56 to 0.76) in the first trimester, 0.74 (IQR 0.52 to 1.18) in the second trimester, and 0.89 (IQR 0.52 to 1.09) in the third trimester (P = 0.02). The median HCV viral load at delivery was 424 561 IU/mL. The vertical transmission rate was 4.7% in HCV RNA-positive women, with no cases in HCV RNA-negative women. CONCLUSION Because of the high rates of poor obstetrical outcomes found in this prospective cohort, population-level screening for HCV in pregnancy should be considered.

Abstract
Liver disease can be observed in pregnant women whether or not related to pregnancy. Liver disorders can be revealed by pruritus, vomiting, jaundice or abnormal liver blood tests during pregnancy. These liver manifestations can lead to the diagnosis of liver disease specifically associated to pregnancy as intrahepatic pregnancy, intrahepatic cholestasis of pregnancy, Hyperemesis gravidarum, acute fatty liver of pregnancy and preeclampsia-induced liver injury. Pregnancy may also be a risk factor for other liver diseases coincident with pregnancy as viral hepatitis, thrombosis, drug toxicity or gallstone. Finally, pre-existing liver disease must be taken into account given the risk of fœto-maternal transmission risk as well as the risk of decompensation of underlying cirrhosis secondary to the hemodynamic changes caused by pregnancy. The aim of this revue is to perform an update on the various situations that can be observed, the principles of management of these liver diseases, in order to reduce the risk of complications and to ensure the best maternal and fetal prognosis.

Abstract
Our objective was to provide a comprehensive review of the current knowledge regarding pregnancy and hepatitis B virus (HBV) or hepatitis C virus (HCV) infection as well as recent efforts to reduce the rate of mother-to-child transmission (MTCT). Maternal infection with either HBV or HCV has been linked to adverse pregnancy and birth outcomes, including MTCT. MTCT for HBV has been reduced to approximately 5% overall in countries including the US that have instituted postpartum neonatal HBV vaccination and immunoprophylaxis with hepatitis B immune globulin. However, the rate of transmission of HBV to newborns is nearly 30% when maternal HBV levels are greater than 200 000 IU ml(-1) (>6 log10 copies ml(-1)). For these patients, new guidelines from the European Association for the Study of the Liver (EASL) and the Asian Pacific Association for the Study of the Liver (APASL) indicate that, in addition to neonatal vaccination and immunoprophylaxis, treating with antiviral agents such as tenofovir disoproxil fumarate or telbivudine during pregnancy beginning at 32 weeks of gestation is safe and effective in preventing MTCT. In contrast to HBV, no therapeutic agents are yet available or recommended to further decrease the risk of MTCT of HCV, which remains 3 to 10%. HCV MTCT can be minimized by avoiding fetal scalp electrodes and birth trauma whenever possible. Young women with HCV should be referred for treatment post delivery, and neonates should be closely followed to rule out infection. New, better-tolerated treatment regimens for HCV are now available, which should improve outcomes for all infected individuals.

Abstract
Hepatitis C virus (HCV) is a well known cause of chronic liver disease in adults, but the burden of HCV in pregnant women and children is underappreciated. The leading route of HCV acquisition in children is vertical transmission. This review will discuss previous studies on the impact of HCV on pregnancy, risk factors for perinatal transmission, HCV transmission rates from mother to infant, what influence the virus has on the exposed or infected infant, and those areas where additional studies are required to advance our understanding of HCV pathogenesis during pregnancy. The rapid expansion of HCV treatment regimens free of interferon and ribavirin will expand future therapeutic opportunities for pregnant women and infected infants.

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
CONTEXT Nonalcoholic Fatty Liver Disease (NAFLD) is common in postmenopausal women. It is associated with metabolic syndrome. However, the influence of hormone replacement therapy in NAFLD development in these women needs to be investigated. This study aimed to describe the clinical characteristics of NAFLD in postmenopausal women, and the relationship between hormone replacement therapy and this disease. METHODS From April 2009 to April 2011, 292 postmenopausal women from National Health System from Northeast of Brazil were selected, and 251 were included in this study. Menopause was defined as the absence of menstruation for 12 consecutive months in otherwise healthy women. Criteria to NAFLD included: presence of steatosis on abdominal ultrasound; history of alcohol consumption less than 20 g/day and exclusion of other liver diseases. All women underwent a clinical evaluation. Standard univariate and multivariate analyses were performed to evaluate the results. RESULTS The mean age was 56.5 ± 6.7 years. Hormone replacement therapy was referred by 21.1% (53) women and 78.9% (198) was not. Prevalence of NAFLD was 37.1% (93/251) in postmenopausal women, 26,4% (14/53) in the group with hormone replacement therapy and 39,9% (79/198) without hormone replacement therapy. Gamma-glutamyl transpeptidase (P = 0.001), alanine transaminase (P<0.01), ferritin (P<0.001) and insulin resistance (homeostatic model assessment of insulin resistance ≥3) (P<0.001) were higher in the group of women with NAFLD diagnosis who did not referred the use of hormone replacement therapy. Metabolic syndrome was also more frequent in women with NAFLD, who did not refer hormone replacement therapy. CONCLUSION In conclusion this data suggests elevated prevalence of NAFLD in postmenopausal women; negative association of hormone replacement therapy and NAFLD.

Abstract
The spectrum of liver disease in pregnancy includes liver disease unrelated to pregnancy, liver diseases that occur with increased frequency or severity in pregnancy, and liver disease specific to pregnancy. Diseases of the liver unique to pregnancy reliably occur at specific points in the gestational spectrum. Thus, gestational age, a comprehensive history, and a clinically driven diagnostic evaluation is critical in approaching a pregnant patient with abnormal liver chemistries or function. Early recognition of these conditions is important and although management may be expectant, some patients require targeted therapy or necessitate prompt delivery, which can be life-saving to both mother and child.

Abstract
Globally, about 1% of pregnant women are persistently infected with the hepatitis C virus (HCV). Mother-to-child transmission of HCV occurs in 3-5% of pregnancies and accounts for most new childhood infections. HCV-specific CD8(+) cytotoxic T lymphocytes (CTLs) are vital in the clearance of acute HCV infections, but in the 60-80% of infections that persist, these cells become functionally exhausted or select for mutant viruses that escape T cell recognition. Increased HCV replication during pregnancy suggests that maternofetal immune tolerance mechanisms may further impair HCV-specific CTLs, limiting their selective pressure on persistent viruses. To assess this possibility, we characterized circulating viral quasispecies during and after consecutive pregnancies in two women. This revealed a loss of some escape mutations in HLA class I epitopes during pregnancy that was associated with emergence of more fit viruses. CTL selective pressure was reimposed after childbirth, at which point escape mutations in these epitopes again predominated in the quasispecies and viral load dropped sharply. Importantly, the viruses transmitted perinatally were those with enhanced fitness due to reversion of escape mutations. Our findings indicate that the immunoregulatory changes of pregnancy reduce CTL selective pressure on HCV class I epitopes, thereby facilitating vertical transmission of viruses with optimized replicative fitness.

Abstract
This study analyses the evolution of liver disease in women with chronic hepatitis C during the third trimester of pregnancy and the post-partum period, as a natural model of immune modulation and reconstitution. Of the 122 mothers recruited to this study, 89 were HCV-RNA+ve/HIV-ve and 33 were HCV-RNA-ve/HIV-ve/HCVantibody+ve and all were tested during the third trimester of pregnancy, at delivery and post-delivery. The HCV-RNA+ve mothers were categorized as either Type-A (66%), with an increase in ALT levels in the post-partum period (>40 U/L; P<0.001) or as Type-B (34%), with no variation in ALT values. The Type-A mothers also presented a significant decrease in serum HCV-RNA levels in the post-delivery period (P<0.001) and this event was concomitant with an increase in Th1 cytokine levels (INFγ, P = 0.04; IL12, P = 0.01 and IL2, P = 0.01). On the other hand, the Type-B mothers and the HCV-RNA-ve women presented no variations in either of these parameters. However, they did present higher Th1 cytokine levels in the partum period (INFγ and IL2, P<0.05) than both the Type-A and the HCV-RNA-ve women. Cytokine levels at the moment of delivery do not constitute a risk factor associated with HCV vertical transmission. It is concluded that differences in the ALT and HCV-RNA values observed in HCV-RNA+ve women in the postpartum period might be due to different ratios of Th1 cytokine production. In the Type-B women, the high partum levels of Th1 cytokines and the absence of post-partum variation in ALT and HCV-RNA levels may be related to permanent Th1 cytokine stimulation.

Abstract
Despite recent advances in the pathogenesis, treatment, and public health response to hepatitis C virus (HCV), HCV as it specifically relates to pregnancy has been a neglected condition. HCV-monoinfected pregnant women have a 2-8% risk of viral transmission to their infant, but the mechanism and timing of mother to child transmission (MTCT) are not fully understood, nor is the natural history of the illness in pregnant women and their offspring. Recognition of HCV-infected pregnant women is relevant because of the long-term health implications for the mother, potential adverse effects of infection on pregnancy outcomes, and the possibility of transmission to their infants. Certain risk factors for MTCT of HCV appear similar to those for human immunodeficiency virus (HIV); however, unlike HIV, effective methods for prevention of HCV vertical transmission have not been developed. It is possible that a better understanding of HCV MTCT and pathogenesis in pregnancy will guide development of useful prevention strategies, particularly as we enter an era where interferon-free drug cocktails may emerge as viable treatment options for HCV.
