Abstract
BACKGROUND The increasing rate of Hepatitis C virus (HCV) infection has been attributed to the substance use epidemic. There is limited data on the current rates of the paralleling HCV epidemic. OBJECTIVES To estimate the prevalence of maternal HCV infection in West Virginia (WV) and identify contributing factors. METHODS Population-based retrospective cohort study of all pregnant individual(s) who gave birth in WV between 01/01/2020 to 01/30/2024 (N = 69,925). Multiple log-binomial regression models were used to estimate the adjusted risk ratio (ARR) and the 95% confidence intervals (CI). RESULTS The rate of maternal HCV infection was 38 per 1,000 deliveries. The mean age of pregnant individual(s) with HCV was 29.99 (SD 4.95). The risk of HCV was significantly higher in White vs. minority racial groups [ARR 1.93 (1.50, 2.49)], those with less than [ARR 1.57 (1.37, 1.79)] or at least high school [ARR 1.31 (1.17, 1.47)] vs. more than high school education, those on Medicaid [ARR 2.32 (1.99, 2.71)] vs. private health insurance, those residing in small-metro [ARR 1.32 (1.17, 1.48)] and medium-metro [ARR 1.41 (1.24, 1.61)], vs. rural areas, and those who smoked [ARR 3.51 (3.10, 3.97)]. HCV risk was highest for those using opioids [ARR 4.43 (3.95, 4.96)]; followed by stimulant use [ARR = 1.79 (1.57, 2.04)]. CONCLUSIONS Our findings highlight that maternal age, race, education, and type of health insurance are associated with maternal HCV infection. The magnitude of association was highest for pregnant individual(s) who smoked and used opioids and stimulants during pregnancy in WV.

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
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.

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
The elimination of hepatitis C is a national priority (https://www.hhs.gov/sites/default/files/Viral-Hepatitis-National-Strategic-Plan-2021-2025.pdf). During 2010-2021, hepatitis C virus (HCV) acute and chronic infections (hereinafter referred to as HCV infections) increased in the United States, consequences of which include cirrhosis, liver cancer, and death. Rates of acute infections more than tripled among reproductive-aged persons during this time (from 0.8 to 2.5 per 100,000 population among persons aged 20-29 years and from 0.6 to 3.5 among persons aged 30-39 years). Because acute HCV infection can lead to chronic infection, this has resulted in increasing rates of HCV infections during pregnancy. Approximately 6%-7% of perinatally exposed (i.e., exposed during pregnancy or delivery) infants and children will acquire HCV infection. Curative direct-acting antiviral therapy is approved by the Food and Drug Administration for persons aged ≥3 years. However, many perinatally infected children are not tested or linked to care. In 2020, because of continued increases in HCV infections in the United States, CDC released universal screening recommendations for adults, which included recommendations for screening for pregnant persons during each pregnancy (Schillie S, Wester C, Osborne M, Wesolowski L, Ryerson AB. CDC recommendations for hepatitis C screening among adults-United States, 2020. MMWR Recomm Rep 2020;69[No. RR-2]:1-17). This report introduces four new CDC recommendations: 1) HCV testing of all perinatally exposed infants with a nucleic acid test (NAT) for detection of HCV RNA at age 2-6 months; 2) consultation with a health care provider with expertise in pediatric hepatitis C management for all infants and children with detectable HCV RNA; 3) perinatally exposed infants and children with an undetectable HCV RNA result at or after age 2 months do not require further follow-up unless clinically warranted; and 4) a NAT for HCV RNA is recommended for perinatally exposed infants and children aged 7-17 months who previously have not been tested, and a hepatitis C virus antibody (anti-HCV) test followed by a reflex NAT for HCV RNA (when anti-HCV is reactive) is recommended for perinatally exposed children aged ≥18 months who previously have not been tested. Proper identification of perinatally infected children, referral to care, and curative treatment are critical to achieving the goal of hepatitis C elimination.

Abstract
BACKGROUND Hepatitis Virus C (HCV) infection rates have trended upwards among pregnant people in the USA since 2009. Existing evidence about HCV infections and maternal outcomes is limited; therefore, we used birth certificate data to investigate the association between HCV infection and maternal health outcomes. METHODS We used the 2017 US birth certificate dataset (a cross-section of 1.4 million birth records) to assess the association between prevalent HCV infection and gestational diabetes, gestational hypertension, and eclampsia. Potential confounding variables included prenatal care, age, education, smoking, presence of sexually transmitted infections (STIs), body mass index (BMI), and weight gain during pregnancy. We restricted our analysis to only women with a first singleton pregnancy. Odds ratios were estimated by logistic regression models and separate models were tested for white and Black women. RESULTS Only 0.31% of the women in our sample were infected with HCV (n = 4412). In an unadjusted model, we observed a modest significant protective association between HCV infection and gestational diabetes (Odds ratio [OR]: 0.83; 95% CI: 0.76-0.96); but this was attenuated with adjustment for confounding variables (Adjusted odds ratio [AOR]: 0.88; 95% CI: 0.76, 1.02). There was no association between HCV and gestational hypertension (AOR: 1.03; 95% CI: 0.91, 1.16) or eclampsia (AOR: 1.15; 95% CI: 0.69, 1.93). Results from the race stratified models were similar to the non-stratified summary models. CONCLUSION We observed no statistically significant associations between maternal HCV infection with maternal health outcomes. Although, our analysis did indicate that HCV may lower the risk of gestational diabetes, this may be attributable to confounding. Studies utilizing more accurately measured HCV infection including those collecting type and timing of testing, and timing of infection are warranted to ensure HCV does not adversely impact maternal and/or fetal health. Particularly in the absence of recommended therapy for HCV during pregnancy.

Abstract
In India, the estimated prevalence of antenatal HCV infection is 0.3%-2.8%, and the rate of mother-to-child transmission has been estimated at 5%-15%. HCV treatment during pregnancy could reduce maternal complications from HCV infection, prevent transmission to the infant, and reduce HCV infection overall in women of childbearing age. However, there are limited studies of HCV treatment with direct-acting antiviral medications during pregnancy, and therefore, direct-acting antivirals are not commonly used for treatment during pregnancy. We describe our institutional experience in this prospective observational study over 3 years at the Sher-I-Kashmir Institute of Medical Sciences, Srinagar, India. Patients with chronic hepatitis C in pregnancy were enrolled and treated with ledipasvir and sofosbuvir after the first trimester. Primary end points were sustained virologic response at 12 weeks, adverse drug reactions, and congenital malformation of the infant. The secondary end point was the transmission of HCV infection to the infant. We enrolled 26 patients in our study. The mean age was 28 years (range of 21-36 y). All patients were noncirrhotic and treatment-naive. The mean HCV RNA before treatment was 9.2 ×10^5 IU/ml. Among the enrolled patients, 19 (73%) were genotype 3, 5 (19%) were genotype 1, and 2 (8%) were genotype 4. All patients achieved sustained virologic response at 12 weeks. Some patients reported nausea (27%), headache (27%), and fatigue (16%). All patients had institutional delivery, and no infant was found to have congenital malformations. No child had detectable HCV RNA at 6 months of age. To our knowledge, we here report results from the largest cohort of pregnant women treated for HCV infection globally. Ledipasvir and sofosbuvir were well tolerated and highly effective for both HCV cure in the mother and elimination of mother-to-child transmission. No congenital abnormalities were detected in our cohort. Elimination of mother-to-child transmission is urgently needed, and this study has shown that treatment of HCV during pregnancy may be a pragmatic approach for the greater benefit of both mother and the newborn.

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
An independent association between chronic hepatitis B virus (HBV) and the development of gestational diabetes (GDM) has been reported in the literature. Ethnic background and regional influences have been demonstrated to play a role in the reporting of incidence rates of GDM among women with chronic HBV. The mechanisms behind this association are poorly understood, but evidence suggests an inflammatory basis. Viral factors such as chronic HBV replication, quantifiable by HBV viral load, have been proposed to contribute to the increasing risk of insulin resistance in pregnancy. More research is needed to better characterise the association and determine if any interventions early in pregnancy for women infected with chronic HBV would mitigate the development of GDM.

Abstract
OBJECTIVE To assess clinical characteristics, trends, and outcomes associated with the diagnosis of hepatitis C virus (HCV) infection during pregnancy. METHODS This cross-sectional study analyzed delivery hospitalizations using the National Inpatient Sample. Temporal trends in both diagnosis of HCV infection and clinical characteristics associated with HCV infection were analyzed using joinpoint regression to estimate the average annual percent change (AAPC) with 95% CIs. Survey-adjusted logistic regression models were fit to assess the association among HCV infection and preterm delivery, cesarean delivery, and severe maternal morbidity (SMM), adjusting for clinical, medical, and hospital factors with adjusted odds ratios (aORs) as the measure of association. RESULTS An estimated 76.7 million delivery hospitalizations were included, in which 182,904 (0.24%) delivering individuals had a diagnosis of HCV infection. The prevalence of HCV infection diagnosed in pregnancy increased nearly 10-fold over the study period, from 0.05% in 2000 to 0.49% in 2019, representing an AAPC of 12.5% (95% CI 10.4-14.8%). The prevalence of clinical characteristics associated with HCV infection also increased over the study period, including opioid use disorder (from 10 cases/10,000 birth hospitalizations to 71 cases/10,000 birth hospitalizations), nonopioid substance use disorder (from 71 cases/10,000 birth hospitalizations to 217 cases/10,000 birth hospitalizations), mental health conditions (from 219 cases/10,000 birth hospitalizations to 1,117 cases/10,000), and tobacco use (from 61 cases/10,000 birth hospitalizations to 842 cases/10,000). The rate of deliveries among patients with two or more clinical characteristics associated with HCV infection increased from 26 cases per 10,000 birth hospitalizations to 377 cases per 10,000 delivery hospitalizations (AAPC 13.4%, 95% CI 12.1-14.8%). In adjusted analyses, HCV infection was associated with increased risk for SMM (aOR 1.78, 95% CI 1.61-1.96), preterm birth (aOR 1.88, 95% CI 1.8-1.95), and cesarean delivery (aOR 1.27, 95% CI 1.23-1.31). CONCLUSION Diagnosis of HCV infection is increasingly common in the obstetric population, which may reflect an increase in screening or a true increase in prevalence. The increase in HCV infection diagnoses occurred in the setting of many baseline clinical characteristics that are associated with HCV infection becoming more common.

[PMID: 35643203 DOI: 10.1016/j.jhep.2022.05.016] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2021] [Revised: 05/05/2022] [Accepted: 05/16/2022] [Indexed: 12/04/2022]
Abstract
BACKGROUND & AIMS With the World Health Organization plan for hepatitis C elimination by the year 2030, and recent guideline recommendations to screen all women during pregnancy for HCV, data on HCV in pregnancy are needed to determine the association of HCV viremia with adverse pregnancy outcomes and mother-to-child transmission (MTCT). METHODS This retrospective cohort study was performed in Ontario, Canada, using population-based administrative healthcare data. Individuals were stratified based on whether they had active HCV viremia during pregnancy or resolved viremia at time of pregnancy. Peak HCV viral load was determined. Logistic regression was used to determine the association of viremia with adverse pregnancy outcomes; maternal HCV RNA levels were evaluated as a predictor of MTCT. RESULTS We identified a total of 2,170 pregnancies in 1,636 women who were HCV RNA positive prior to pregnancy; 1,780 (82%) pregnancies occurred in women who were HCV RNA positive during pregnancy. Patients who were HCV RNA positive during pregnancy were more likely to have preterm delivery (18% vs. 12%, p = 0.002), intrahepatic cholestasis of pregnancy (4% vs. <2%, p = 0.003), and post-partum hemorrhage (9% vs. 5%, p = 0.013), and less likely to have gestational diabetes (6% vs. 10%, p = 0.008) than those with resolved infection. Only 511 (29%) infants had screening consistent with guidelines after birth; there was an estimated 3.5% risk of MTCT. HCV RNA ≥6.0 log10 IU/ml was significantly associated with MTCT (exact odds ratio 3.4, p = 0.04). CONCLUSION Active HCV viremia among individuals with a history of HCV infection significantly increases adverse pregnancy outcomes. Few infants are screened for MTCT. Higher HCV RNA is associated with increased risk of MTCT. LAY SUMMARY The prevalence of hepatitis C has increased in women of child-bearing age and has important implications for women who become pregnant and their infants. We evaluated the effect that hepatitis C has on pregnancy outcomes as well as the rate of hepatitis C transmission to infants in a large database with linked mother-infant records. We found that active hepatitis C during pregnancy increased the risk of pregnancy complications. We also identified very low rates of testing of infants born to mothers with hepatitis C, but found higher rates of hepatitis C transmission to infants in mothers with higher virus levels.

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
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.

Abstract
Objective To determine the frequency of hepatitis A, B, C, and E viruses (HAV, HBV, HCV, HEV) in pregnant women with acute hepatitis presenting to the medical units of HMC, Peshawar. Methods This is a descriptive cross-sectional study in which 442 pregnant women, either multi or primigravida, with yellow discolouration of the sclerae of the eyes and elevated alanine aminotransferase (ALT) > 100 U/L on laboratory tests were chosen by convenience (non-probability) sampling to assess the frequency of HAV, HBV, HCV, HEV. Results The majority, i.e., 58.8%, were in the age range of >30 years and presented in the third trimester. Of the subjects, 81.90% had parity in the range of 1-5, 89.4% were multigravida, 71.3% were illiterate, and 73.1% were in the low-income category. Anti-HEV was detected in 47.3% of pregnant women, Anti-HCV in 30.3%, Hepatitis B surface antigen (HBsAg) in 11.5%, Hepatitis A-IgM in 5%, and 5.90% of the cases were virus-free. Conclusions HBV, HCV, and HEV exposure, in particular, may have a substantially larger impact on pregnancy and neonatal outcomes than HAV. As a result, at the first prenatal appointment, standard viral hepatitis screening in pregnant women may need to be reviewed.

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
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
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
Pregnancy is a unique immunological condition in which an "immune-diplomatic" dialogue between trophoblasts and maternal immune cells is established to protect the fetus from rejection, to create a privileged environment in the uterus and to simultaneously be alert to any infectious challenge. The maternal-placental-fetal interface (MPFI) performs an essential role in this immunological defense. In this review, we will address the MPFI as an active immuno-mechanical barrier that protects against viral infections. We will describe the main viral infections affecting the placenta and trophoblasts and present their structure, mechanisms of immunocompetence and defensive responses to viral infections in pregnancy. In particular, we will analyze infection routes in the placenta and trophoblasts and the maternal-fetal outcomes in both. Finally, we will focus on the cellular targets of the antiviral microRNAs from the C19MC cluster, and their effects at both the intra- and extracellular level.

Abstract
Hepatitis C virus (HCV) elimination has evolved into a coordinated global effort. Canada, with more than 250,000 chronically infected individuals, is among the countries leading this effort. The 9th Canadian Symposium on HCV, held in February 2020, thus established and addressed its theme, 'advances in HCV research and treatment towards elimination', by gathering together basic scientists, clinicians, epidemiologists, social scientists, and community members interested in HCV research in Canada. Plenary sessions showcased topical research from prominent international and national researchers, complemented by select abstract presentations. This event was hosted by the Canadian Network on Hepatitis C (CanHepC), with support from the Public Health Agency of Canada and the Canadian Institutes of Health Research and in partnership with the Canadian Liver Meeting. CanHepC has an established record in HCV research by its members and in its advocacy activities to address the care, treatment, diagnosis, and immediate and long-term needs of those affected by HCV infection. Many challenges remain in tackling chronic HCV infection, such as the need for a vaccine; difficult-to-treat populations and unknown aspects of patient subgroups, including pregnant women and children; vulnerable people; and issues distinct to Indigenous peoples. There is also increasing concern about long-term clinical outcomes after successful treatment, with the rise in comorbidities such as diabetes, cardiovascular disease, and fatty liver disease and the remaining risk for hepatocellular carcinoma in cirrhotic individuals. The symposium addressed these topics in highlighting research advances that will collectively play an important role in eliminating HCV and minimizing subsequent health challenges.

Abstract
Although pregnancy is rare in women with cirrhosis, it is increasingly prevalent in an era of modern assisted conception techniques and improved awareness, monitoring and management of underlying liver disease. After overcoming the difficulties of subfertility and becoming pregnant, women undergo a 'high-risk' pregnancy which can be complicated by variceal haemorrhage (≤50%) and hepatic decompensation (≤25%). Management of these complications are similar to non-pregnant individuals. However, there are a few caveats to consider. These pregnancies are associated with adverse maternal and foetal outcomes, such as mortality (0%-8%) and prematurity (19%-67%) in the newborn, and mortality (0%-14%), pregnancy-induced hypertension (5%-22%) and post-partum haemorrhage (5%-45%) in the mother. Pre-pregnancy counselling, use of predictive scores and appropriate variceal screening during pregnancy can stratify patients and improve outcomes. This review focusses on the complications that can occur during pregnancy in women with cirrhosis.

Abstract
Viral infections are common complications of pregnancy. Although some infections have maternal sequelae, many viral infections can be perinatally transmitted to cause congenital or chronic infection in fetuses or infants. Treatments of such infections are geared toward reducing maternal symptoms and complications and toward preventing maternal-to-child transmission of viruses. The authors review updates in the treatment of herpes simplex virus, cytomegalovirus, hepatitis B and C viruses, human immunodeficiency virus, and COVID-19 during pregnancy.

Non-communicable Diseases in Pregnant and Postpartum Women Living with HIV: Implications for Health Throughout the Life Course. Curr HIV/AIDS Rep 2021; 18:73-86. [PMID: 33400169 DOI: 10.1007/s11904-020-00539-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/07/2020] [Indexed: 12/30/2022]
Abstract
PURPOSE OF REVIEW The development of non-communicable diseases (NCDs) in pregnant women living with HIV can be a harbinger of future NCD-related morbidity and mortality. This review focuses on the NCDs that complicate pregnancy and the postpartum period, including hypertensive complications, hyperglycemic disorders, excessive gestational weight gain, and bone mineral density losses. For each disease process, we explore the role of HIV as a possible driver of excess risk, the immediate consequences of these complications on pregnancy outcomes and maternal and infant health, and possible implications for long-term women's health. RECENT FINDINGS Countries with the highest burden of HIV also shoulder a high burden of NCDs that complicate pregnancy, including hypertensive disorders, hyperglycemic disorders, weight gain, and osteopenia. This double burden of disease is a significant public health threat for reproductive-age women, with the potential for serious short- and long-term consequences for both women and their infants. Additionally, as the global first-line antiretroviral therapy regimens increasingly include integrase inhibitors, unhealthy weight gain associated with this drug class poses additional risk for NCD-related pregnancy complications and their persistence postpartum. Further research is needed to better define prevalence of NCD complications in pregnancy, elucidate HIV-specific and traditional factors associated with poor outcomes, and to develop interventions to reduce risk and avoid downstream complications in those at highest risk.

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.

Eur J Obstet Gynecol Reprod Biol 2020; 254:195-199. [PMID: 33017709 DOI: 10.1016/j.ejogrb.2020.09.023] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Revised: 09/10/2020] [Accepted: 09/14/2020] [Indexed: 12/25/2022]
Abstract
OBJECTIVES The study evaluates the trend over time and the results of serological screening for hepatitis C infection in pregnancy and obstetric and neonatal outcomes. STUDY DESIGN It is a retrospective observational study of all pregnant women delivered in maternity units in Trento province, North East Italy, between 2009-2018. Serological screening data for hepatitis C virus were collected through the birth attendance certificate that is the mandatory tool in Italy for the birth report and the monitoring of the pregnancy, childbirth and health of the newborn. We also used the informations collected in the Hospital information system in order to get, for confirmed positive cases, the data of the entire serological profile. On this basis, we calculated the coverage of serological screening, the seroprevalence of the infection and the obstetric and neonatal outcomes. RESULTS A total of 45,493 pregnant women were analysed, 75.5% Italians and 24.5% foreigners. The mean coverage for serological HCV screening in pregnancy was 99.4%. 177 women tested positive for HCV antibodies (107 Italian and 70 foreign women). Mean overall seroprevalence in pregnant women was 3.9‰ (95% CI: 3.8-4.0); amongst Italians it was 3.2‰ (95% CI: 3.0-3.4) and amongst foreigners it was 6.1‰ (95% CI: 5.9-6.2). The highest seroprevalence was recorded in mothers coming from Asian countries. HCV positive mothers present an excess risk for intrahepatic cholestasis and gestational diabetes compared to HCV negative mothers. The neonatal outcomes considered bring to light a statistically significant increase in preterm births, low birth weight, elective Caesarean births, hospitalisation at birth and bottle- or mixed-feeding vs breast-only feeding. There are differences in obstetric and neonatal outcomes in relation to the HCV positive subgroup of the mother defined in particular by exposure to smoke and/or opioids. CONCLUSIONS The availability and integration of current information sources allows you to verify compliance with national recommendations on the serological screening of hepatitis C virus infection, to determine infection seroprevalence, the characteristics of the cases and the obstetric and neonatal outcomes. Only part of the maternal and neonatal outcomes studied can be attributed to the presence of HCV.

Hepatitis C Seroprevalence Among Consecutive Labor and Delivery Admissions in Two New York City Hospitals. Open Forum Infect Dis 2020; 7:ofaa514. [PMID: 33241070 PMCID: PMC7676505 DOI: 10.1093/ofid/ofaa514] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2020] [Accepted: 10/19/2020] [Indexed: 12/13/2022] Open
Abstract
Background Rates of hepatitis C virus (HCV) among women of childbearing age have increased as a result of the opioid epidemic, especially in the nonurban white population. Recently updated US Preventative Services Task Force and Centers for Disease Control and Prevention guidance have recommended universal HCV screening during pregnancy, but obstetrics societies have not yet endorsed this recommendation. We evaluated the seroprevalence of HCV among pregnant women in an inner-city population, compared rates with other sexually transmitted infections (STIs) screened for during pregnancy, and evaluated factors associated with HCV positivity. Methods We performed a prospective seroprevalence study of consecutive labor and delivery admissions (both antepartum complications and delivery admissions) by testing serum samples for HCV antibody over 9 months at 2 major hospital settings in New York City. Results Fifty-six of 7373 (0.75%; 95% confidence interval [CI], 0.57–0.98) patients screened positive for HCV, with 28 of 4013 (0.70%; 95% CI, 0.46%–1.01%) and 28 of 3413 (0.82%; 95% CI, 0.55%–1.18%) at each hospital. Forty-one percent of HCV-positive patients had any reported HCV risk factors. Hepatitis C virus-positive patients were less likely to have private insurance and more likely to have a history of cannabis, cocaine, and injection drug use (P < .001). The HCV rates were higher among antepartum admissions compared with delivery admissions and higher than that of hepatitis B virus (0.65%; 95% CI, 0.48–0.86), human immunodeficiency virus (0.27%; 95% CI, 0.16–0.42), and syphilis (0.16%; 95% CI, 0.08–0.28). Conclusions We found a higher than expected HCV seroprevalence among pregnant women and higher than most other STIs routinely screened for in pregnancy. Most patients had no risk factors. These findings support universal screening for hepatitis C during pregnancy.

Abstract
OBJECTIVE Many modifiable maternal behaviors and experiences before and during pregnancy are associated with adverse health outcomes. The relationship between a number of maternal and gestational disorders and perinatal outcomes (preterm birth, low birth weight and neonatal intensive care unit (NICU)) admission in the Central New York population is determined using the Statewide Perinatal Data System, in a retrospective population-based cohort study. METHODS Singleton births excluding newborns with congenital anomalies among 165,739 women between 2004 and 2012 are included in this study. Multivariable logistic regression analysis is used to estimate odds ratios (OR) and 95% confidence intervals (CI) adjusted for maternal age, race, education, employment, parity, body mass index, smoking, drug use, depression, abortions, gender of child, prenatal care, and hospital level. RESULTS Previous preterm birth and vaginal bleeding are independent high-risk factors for all three perinatal outcomes, pre-pregnancy diabetes (OR 4.95, 95% CI 4.34, 5.64) for preterm birth and (OR 7.45, 95% CI 6.58, 8.44) for NICU admission; and gestational hypertension (OR 4.35, 95% CI 4.03, 4.70) for low birth weight. Among infections, bacterial vaginosis is retained in the multivariable model as a risk factor for preterm and low birth weight while hepatitis C is a risk factor for NICU admission. CONCLUSIONS Our findings suggest the continued importance of addressing the need to provide preconception and inter conception care for women since many modifiable risk factors are correlated and need to be addressed well before the woman becomes pregnant.

Abstract
OBJECTIVE To quantify the reported prevalence and trend of maternal hepatitis C virus (HCV) infection in the United States (2009-2017) and identify maternal characteristics and obstetric outcomes associated with HCV infection during pregnancy. METHODS We conducted a population-based retrospective cohort study of all live births in the United States for the period 2009 through 2017 using National Center for Health Statistics birth records. We estimated reported prevalence and trends over this time period for the United States. We also evaluated demographic factors and pregnancy outcomes associated with maternal HCV infection for a contemporary U.S. cohort (2014-2017). RESULTS During the 9-year study period, there were 94,824 reported cases of maternal HCV infection among 31,207,898 (0.30%) live births in the United States. The rate of maternal HCV infection increased from 1.8 cases per 1,000 live births to 4.7 cases per 1,000 live births (relative risk [RR] 2.7, 95% CI 2.6-2.8) in the United States. After adjusting for various confounders in the contemporary U.S. cohort (2014-2017), demographic characteristics associated with HCV infection included non-Hispanic white race (adjusted RR 2.8, 95% CI 2.7-2.8), Medicaid insurance (adjusted RR 3.3, CI 3.2-3.3), and cigarette smoking (adjusted RR 11.1, CI 10.9-11.3). Co-infection during pregnancy with hepatitis B (adjusted RR 19.2, CI 18.1-20.3), gonorrhea, chlamydia, or syphilis were also associated with maternal HCV infection. Obstetric and neonatal outcomes associated with maternal HCV infection included cesarean delivery, preterm birth, maternal intensive care unit admission, blood transfusion, having small-for-gestational-age neonates (less than the 10th percentile) birth weight, neonatal intensive care unit admission, need for assisted neonatal ventilation, and neonatal death. CONCLUSION The reported prevalence of maternal HCV infection has increased 161% from 2009 to 2017.

Abstract
Background & aim Worldwide, measures are being implemented to eradicate hepatitis B (HBV) and C (HCV) viruses, which can be transmitted from the mother during childbirth. This study aims to determine the prevalence of HBV and HCV in pregnant women in Spain, focusing on country of origin, epidemiological factors and risk of vertical transmission (VT). Methodology Multicentre open-cohort study performed during 2015. HBV prevalence was determined in 21870 pregnant women and HCV prevalence in 7659 pregnant women. Epidemiological and risk factors for VT were analysed in positive women and differences between HBV and HCV cases were studied. Results HBV prevalence was 0.42% (91/21870) and HCV prevalence was 0.26% (20/7659). Of the women with HBV, 65.7% (44/67) were migrants. The HBV transmission route to the mother was unknown in 40.3% of cases (27/67) and VT in 31.3% (21/67). Among risk factors for VT, 67.7% (42/62) of the women had viraemia and 14.5% (9/62) tested HBeAg-positive. All of the neonates born to HBV-positive mothers received immunoprophylaxis, and none contracted infection by VT. In 80% (16/20) of the women with HCV, the transmission route was parenteral, and nine were intravenous drug users. Viraemia was present in 40% (8/20) of the women and 10% (2/20) were HIV-coinfected. No children were infected. Women with HCV were less likely than women with HBV to breastfeed their child (65% vs. 86%). Conclusions The prevalences obtained in our study of pregnant women are lower than those previously documented for the general population. Among the women with HBV, the majority were migrants and had a maternal family history of infection, while among those with HCV, the most common factor was intravenous drug use. Despite the risk factors observed for VT, none of the children were infected. Proper immunoprophylaxis is essential to prevent VT in children born to HBV-positive women.

Abstract
OBJECTIVES To analyze risk factors for the presence of sexually transmitted and blood-borne infections (STBBIs) in pregnancy and to determine whether pregnant women with STBBIs are more likely to experience adverse pregnancy outcomes. METHODS This retrospective cohort study involved analyzing the electronic records of 3460 pregnant women followed at Sainte-Justine Hospital in Montréal, Québec, between March 2017 and January 2019. An outcome is defined as a pregnancy where the woman has at least one positive laboratory result for chlamydia, gonorrhea, syphilis, hepatitis B, or hepatitis C (i.e., has one or multiple STBBIs). We performed a logistic regression analysis to determine adjusted odds ratios (aORs) for the risk factors of STBBIs in pregnant women. RESULTS We identified 84 positive STBBI cases, an overall prevalence of 2.4% (95% CI 1.9-2.9). A logistic regression analysis showed the following factors to be significantly associated with the presence of STBBIs in pregnancy: age <20 years (OR 4.75; 95% CI 1.89-11.96), age 20-29 years (OR 2.38; 95% CI 1.37-4.14), Afro-Caribbean origin (OR 4.12; 95% CI 1.83-9.27), other non-Caucasian origin (OR 2.38; 95% CI 1.20-4.70), and history of STBBIs (OR 2.33; 95% CI 1.02-5.36). STBBIs were not significantly associated with social and material deprivation indices nor were they associated with low birth weight or preterm birth. CONCLUSION This study shows age <20 years, age 20-29 years, Afro-Caribbean or other non-Caucasian origin and history of STBBIs to be risk factors for the presence of STBBIs in pregnancy. These results will allow us to propose interventions to reduce STBBIs in women with common risk factors as part of a comprehensive approach to perinatal care.

Abstract
Liver disease in pregnancy may present as a disorder that is unique to pregnancy or as an acute or chronic liver disease occurring coincidentally in pregnancy. Hepatic diseases that are unique to pregnancy include hyperemesis gravidarum; preeclampsia/eclampsia; the syndrome of hemolysis, elevated liver enzymes, and low platelets; intrahepatic cholestasis of pregnancy; and acute fatty liver of pregnancy. Acute and chronic forms of primary hepatic disorders that are seen in pregnancy include viral hepatitis, autoimmune hepatitis, nonalcoholic fatty liver disease, and cirrhosis. Because of the need to consider both maternal and fetal health, there are special considerations for the implementation of diagnostic strategies and pharmacologic therapies for liver disease that occurs in pregnancy. An understanding of the pathogenesis and expression of liver diseases in pregnancy has been evolving, and various diagnostic and prognostic tools have been studied in order to determine noninvasive approaches to identifying and staging of such diseases. Investigations have also been underway to evaluate the safety and utility of existing and new therapeutic agents that previously were thought to not be compatible with pregnancy. This review will explore updates in the epidemiology, diagnosis, and management of various liver diseases seen in pregnancy.

Abstract
BACKGROUND/AIMS The vertical transmission of hepatitis B virus, hepatitis C virus (HCV), and human immunodeficiency virus (HIV) infections are essential public health problems. In this study, we aimed to investigate the seroprevalence of the aforementioned infections among pregnant women. MATERIALS AND METHODS This study was done retrospectively on pregnant women who presented for antenatal follow-up and delivery between 2013 and 2016. Data were collected from the hospital's electronic health records and patient files. Blood samples were analyzed at the microbiology laboratory of the hospital. HBsAg, anti-HBs, anti-HCV, and anti-HIV titers were tested using the chemiluminescence enzyme immunoassay method (Architect, Abbott Laboratories, USA). RESULTS HBsAg and anti-HBs levels were tested in 35,295 pregnant women aged 18-45 years. The HBsAg and anti-HBs levels were positive in 425 (1.2%) and 9583 (27.7%) patients, respectively. From 2013 to 2016, the HBV carrier rates have continuously decreased from 1.4% to 0.8%, whereas the anti-HBs positivity has increased from 25.4% to 30.2%. Anti-HCV was detected in 6 of the 9709 (0.06%) patients. All the 7113 pregnant women screened for HIV showed negative results. CONCLUSION Hepatitis B carrier rates among pregnant women gradually decreased with a simultaneous increase in the immunity rates. HCV seroprevalence was low and HIV positivity was not encountered in the study population.

Many unique challenges are associated with hepatitis C infection in mothers and children. The preconception, antenatal, and postnatal phases each offer opportunities to reduce transmission of the virus from mother to infant or to identify the need for treatment. Management of children and youth with hepatitis C is now entering the era of direct-acting antivirals. Improvements are needed in the identification of infected mothers and children and their linkage to appropriate expert care.

Review article: direct-acting antivirals for the treatment of HCV during pregnancy and lactation - implications for maternal dosing, foetal exposure, and safety for mother and child. Aliment Pharmacol Ther 2019; 50:738-750. [PMID: 31448450 PMCID: PMC6773363 DOI: 10.1111/apt.15476] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2019] [Revised: 07/25/2019] [Accepted: 08/02/2019] [Indexed: 12/11/2022]
Abstract
BACKGROUND With the global efforts to eradicate hepatitis C virus (HCV), treatment during pregnancy is becoming a priority for research as this, and maternal cure should reduce vertical transmission. However, as information on the efficacy and safety of direct-acting antivirals (DAAs) in pregnancy is generally lacking, treatment of HCV infection during pregnancy is not currently recommended. AIM To provide an overview of current knowledge regarding maternal exposure, placental handling and safety of DAAs during pregnancy and lactation METHODS: A literature search was performed focusing on the effect of pregnancy on maternal exposure to DAAs, the placental handling of DAAs, the safety of DAAs for mother and child during pregnancy and the safety of DAAs during lactation. RESULTS Exposure to all DAAs studied is likely to be altered during pregnancy, mostly related to pregnancy-induced effects on drug absorption and metabolism. Although animal studies show that most DAAs are reported to cross the placenta and transfer into breast milk, most DAA combinations show a favourable safety profile. Because of the rapid viral decline after treatment initiation, and to avoid the critical period of organogenesis, treatment may be started at the end of the second trimester or early third trimester. CONCLUSIONS Treatment of HCV infection during pregnancy is realistic, as DAAs are highly effective and treatment duration is relatively short. There is an urgent need to study DAAs during pregnancy and lactation to contribute to the goal of HCV elimination.

Abstract
Viral infections are common complications of pregnancy. Although some infections have maternal sequelae, many viral infections can be perinatally transmitted to cause congenital or chronic infection in fetuses or infants. Treatments of such infections are geared toward reducing maternal symptoms and complications and toward preventing maternal-to-child transmission of viruses. This article reviews the treatment of herpes simplex virus, cytomegalovirus, hepatitis B and C viruses, and human immunodeficiency virus during pregnancy.

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
Purpose of review The purpose of this review is to discuss the reasons for HCV testing during pregnancy and to review what is known about antiviral treatment during pregnancy. Recent findings Hepatitis C virus affects over 3 million persons in the United States and is one of the leading infectious causes of death. While HCV is most commonly transmitted via parenteral exposures, thus affecting people who inject drugs, it is also transmitted from mother-to-child. Due to an expanding opioid crisis, an increasing number of women of childbearing age are now infected, resulting in transmission to infants. Risk-based screening has never been proven effective and thus universal screening of pregnant women for HCV infection has been recommended. Summary Obstetricians may play a key role in the U.S. by implementing universal testing for HCV in pregnant women, thereby enhancing the health of mothers and identifying children at risk.

Abstract
BACKGROUND Chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infection is frequent in HIV-infected persons but their impact on pregnant HIV-infected women is understudied. We explored whether these coinfections are associated with adverse pregnancy outcomes and lower response to antiretroviral therapy (ART). METHODS Pregnancies in HIV-1-infected women included in the ANRS French Perinatal Cohort between 2005 and 2013 were analyzed if HBV and HCV infection statuses were available. RESULTS Among 4236 women, the prevalence of HBV (HBs Ag+) and HCV (RNA+) were 6.2% (95% confidence interval: 5.4 to 6.8) and 1.7% (1.3 to 2.1), respectively. HCV coinfection was strongly associated with a history of drug use; HBV coinfection was 6 times more frequent in women born in Sub-Saharan Africa than in European France. Baseline HIV viral load, CD4 count, and HIV care during pregnancy were similar in coinfected and monoinfected HIV mothers, except that 90% of HBV/HIV women were receiving tenofovir and/or lamivudine or emtricitabine. HCV coinfection was significantly associated with cholestasis [adjusted odds ratio: 4.1 (1.5-10.8), P = 0.005], preterm delivery [3.0 (1.6-5.7), P < 0.001], lower CD4 [2.6 (1.0-6.4), P < 0.001], and detectable viral load [2.3 (1.0-5.5), P = 0.06] at the end of pregnancy. HBV coinfection was not associated with any of these outcomes. CONCLUSIONS In HIV-infected women, chronic HBV infection, mostly treated using targeted ART, had no major impact on the course of pregnancy. By contrast, chronic HCV infection was associated with a higher risk of obstetrical complications and a poorer immune-virological response to ART. It is yet unknown whether cure of HCV infection before conception can limit these adverse outcomes.

Abstract
BACKGROUND Twins with discordant growth have increased risks of perinatal mortality and morbidity. Previous studies have identified a number of risk factors for inter-twin birth weight discordance, yet no study has examined the effect of maternal hepatitis C infection. METHODS We used the twin birth records extracted from the 2011 to 2015 United States birth records created by the Centers for Disease Control and Prevention. The outcome variable of this study was inter-twin birth weight discordance, defined as [(birth weight of larger twin-birth weight of smaller twin) / birth weight of larger twin]. The independent association of hepatitis C infection with birth weight discordance was examined using the gamma regression or log binomial regression, adjusted by potential confounders. RESULTS Of the 270,256 twin pairs included in the final analysis, 850 (0.31%) had positive hepatitis C. Compared to mothers without hepatitis C, mothers with hepatitis C positive tended to have higher risk of birth weight discordance, but with no statistical significance. After adjustment for potential confounding factors, hepatitis C positive became a significant risk factor for birth weight discordance >25% (relative risk 1.14, 95% confidence interval 1.02-1.29). Sensitivity analyses (by treating birth weight discordance as a continuous outcome or dichotomizing into by different cutoffs) yielded similar results, with relative risks ranging from 1.07 to 1.12 (all P<0.05). CONCLUSION Maternal hepatitis C positive is associated with inter-twin birth weight discordance, an important adverse infant outcome in twin pregnancies, although the effect size is small.

Abstract
INTRODUCTION Many women living with hepatitis C (HCV) are of childbearing age. While the risk of vertical HCV transmission has been well established, the impact of HCV on pregnancy outcomes are equivocal, with some studies reporting risks of preterm birth, low gestational weight, gestational diabetes and hypertension, while other studies report no such risks. With the shift of the HCV treatment landscape to more effective, tolerable and shorter medications, understanding pregnancy outcomes of women living with HCV are an important consideration in order to provide a baseline from which to consider the usefulness and safety of HCV treatment for this population. The objective of this systematic review will be to investigate pregnancy outcomes associated with maternal HCV infection. METHODS AND ANALYSIS This systematic review will incorporate articles relevant to pregnancy outcomes among women living with HCV (eg, gestational diabetes and caesarean delivery). Articles will be retrieved from academic databases including MEDLINE, EMBASE, CINAHL, clinicaltrial.gov and the Cochrane Library and hand searching of conference proceedings and reference lists. A database search will not be restricted by date, and conference abstract will be restricted to the past 2 years. The Newcastle-Ottawa Quality Assessment Scale will be used to assess the quality of the retrieved studies. Data will be extracted and scored independently by two authors. A narrative account will synthesise the findings to answer the objectives of this review. ETHICS AND DISSEMINATION This systematic review will synthesise the literature on the pregnancy outcomes of women living with HCV. Results from this review will be disseminated to clinical audiences, community groups and policy-makers, and may support clinicians and decision-makers in developing guidelines to promote best outcomes for this population.

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 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
Several infections have unique consequences or considerations in pregnancy. Some common infections such as urinary tract infections, influenza, sexually transmitted diseases, and vaginitis affect pregnant women differently than the general population, can cause pregnancy complications, and require treatments that are safe in pregnancy. Infections such as hepatitis B and C and human immunodeficiency virus can be transmitted vertically and therefore management focuses on decreasing perinatal transmission. Certain infections can be transmitted in utero and cause congenital infections. Classically, these were grouped together as the TORCH infections, although now several others, including varicella virus, parvovirus, and Zika virus, have also been recognized.

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
OBJECTIVE To describe the most current evidence for the use of direct-acting antivirals (DAAs) to treat hepatitis C along the pregnancy-pediatric continuum in the United States. DATA SOURCES The MEDLINE/PubMed databases were searched (January 1995 to February 2018) for articles in English using the terms: hepatitis C, vertical transmission, pregnancy, pediatrics, ribavirin, interferon, direct acting antivirals, daclatasvir, dasabuvir, elbasvir, glecaprevir, grazoprevir, ledipasvir, ombitasvir, paritaprevir, pibrentasvir, simeprevir, sofosbuvir, and velpatasvir. STUDY SELECTION AND DATA EXTRACTION All relevant studies, meta-analyses, systematic reviews, guidelines, and review articles were evaluated for inclusion. References from pertinent articles were assessed for additional content that was not found during the initial search. DATA SYNTHESIS The primary route of transmission for hepatitis C virus (HCV) in pediatric patients is vertical transmission (VT), with the rate estimated to be 5.8%. Screening for HCV during pregnancy is not routinely part of clinical care, and the data for the use of DAAs in pregnancy is limited. A significant number of infected infants will clear the HCV infection spontaneously, and ledipasvir/sofosbuvir and sofosbuvir have recently been Food and Drug Administration approved for use in pediatric patients older than 12 years. CONCLUSIONS Data to determine the best treatment point along the pregnancy-pediatric continuum are limited; however, given the lack of human data for use of DAAs during pregnancy, low rate of VT, high rate of spontaneous pediatric clearance, and recent approval of DAAs for pediatric patients, treatment of chronically infected children seems to be the optimal strategy currently.

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.
