Work HM, Hackett JC, Lampe JN. HCV Antiviral Drugs Have the Potential to Adversely Perturb the Fetal-Maternal Communication Axis through Inhibition of CYP3A7 DHEA-S Oxidation. Drug Metab Dispos 2024; 52:516-525. [PMID: 38267095 PMCID: PMC11114604 DOI: 10.1124/dmd.123.001434] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2023] [Revised: 12/21/2023] [Accepted: 01/19/2024] [Indexed: 01/26/2024] Open
Abstract
The hepatitis C virus (HCV) poses a great risk to pregnant people and their developing fetus, yet no HCV antiviral treatment guidelines have been established. While there has been a substantial increase in the development of HCV antivirals, the effect they have on the developing fetus remains poorly defined. Many of these drugs are metabolized through the cytochrome P450 CYP3A pathway, which is mediated by cytochrome P450 3A7 (CYP3A7) in the fetus and developing infant. In this study, we sought to investigate the effect HCV antivirals have on CYP3A7 metabolism, as this CYP enzyme plays a vital role in proper fetal and neonatal development. Of the 13 HCV antivirals we investigated, 8 (∼62%) inhibited CYP3A7 metabolic activity by 50% or more at a concentration of 20 µM. Furthermore, paritaprevir, asunaprevir, simeprevir, danoprevir, and glecaprevir all had observed half-maximal inhibitory concentrations between the range of 10 and 20 µM, which is physiologically relevant in comparison with the Km of dehydroepiandrosterone-sulfate (DHEA-S) oxidation (reported to be between 5 and 20 µM). We also discovered that paritaprevir is a time-dependent inhibitor of CYP3A7, which shifts the IC50 ∼twofold from 11 µM to 5 µM. Upon further characterization, paritaprevir inactivates DHEA-S metabolism by CYP3A7, with KI and Kinact values of 4.66 µM and 0.00954 minute-1, respectively. Depending on treatment plan and off-label drug use, HCV treatment could adversely affect the fetal-maternal communication axis by blocking fetal CYP3A7 metabolism of important endogenous hormones. SIGNIFICANCE STATEMENT: The prevalence of HCV in pregnant people is estimated at between 1% and 8% of the global population, yet little to no information exists about the risk antiviral treatment poses to the developing fetus. There is a potential risk of drugs adversely affecting mother-fetal communication by inhibiting fetal hepatic CYP3A7, an integral enzyme for estriol production. We discovered that five HCV antivirals inhibited DHEA-S metabolism by CYP3A7, and paritaprevir inactivated the enzyme. Our studies demonstrate the potential threat these drugs pose to proper fetal development.

An insight into the hepatoprotective role of Velpatasvir and Sofosbuvir per se and in combination against carbon tetrachloride-induced hepatic fibrosis in rats. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2023; 30:95660-95672.

Abstract
Hepatitis C is a global health issue. Hepatitis C Virus (HCV) induces fibrosis by redox reactions, which involve the deposition of collagen in extracellular matrix (ECM). This study aimed to examine the antifibrotic effect of direct-acting antivirals; Sofosbuvir and Velpatasvir, per se and in combination against carbon tetrachloride (CCl4)-induced fibrosis in rats. Carbon tetrachloride (intraperitoneal; 0.5 ml/kg) twice weekly for six weeks was used to induce hepatic fibrosis in rats. After two weeks of CCl4, oral administration of Sofosbuvir (20 mg/kg/d) and Velpatasvir (10 mg/kg/d) was administered to rats for the last four weeks. Liver function tests (LFTs), renal function tests (RFTs), oxidative stress markers, and the levels of TNF-a, NF-κB, and IL-6 were measured through ELISA and western blotting at the end of the study. CCl4 significantly ameliorated the values of RFTs, LFTs and lipid profiles in the diseased group, which were normalized by the SOF and VEL both alone and in combination. These drugs produced potent antioxidant effects by significantly increasing antioxidant enzymes. From the histopathology of hepatic tissues of rats treated with drugs, the antifibrotic effect was further manifested, which showed suppression of hepatic stellate cells (HSCs) in treated rats, as compared to the disease control group. The antifibrotic effect was further demonstrated by significantly decreasing the levels of TNF-a, NF-κB and IL-6 in serum and hepatic tissues of treated rats as compared to the disease control group. Sofosbuvir and Velpatasvir alone and in combination showed marked inhibition of fibrosis in the CCl4-induced non-HCV rat model, which was mediated by decreased levels of TNF-a/NF-κB and the IL-6 signaling pathway. Thus, it can be concluded that Sofosbuvir and Velpatasvir might have an antifibrotic effect that appears to be independent of their antiviral activity.

Abstract
The prevalence of chronic maternal disease is rising in the last decades in the developed world. Recent evidence indicated that the incidence of chronic maternal disease ranges from 10 to 30% of pregnancies worldwide. Several epidemiological studies in mothers with chronic diseases have mainly focused on the risk for adverse obstetric outcomes. Evidence from these studies supports a correlation between maternal chronic conditions and adverse perinatal outcomes, including increased risk for preeclampsia, cesarean section, preterm birth, and admission in the Neonatal Intensive Care Unit (NICU). However, there is a knowledge gap pertaining to the management of these women during lactation. This review aimed at summarizing the available research literature regarding breastfeeding in mothers with chronic diseases. Adjusted and evidence-based support may be required to promote breastfeeding in women with chronic diseases; however, our comprehension of breastfeeding in this subpopulation is still unclear. The literature related to breastfeeding extends in various scientific areas and multidisciplinary effort is necessary to compile an overview of current evidence and knowledge regarding breastfeeding issues in mothers with chronic diseases.

Abstract
Diabetes mellitus (DM) and hepatitis C virus (HCV) infection are prevalent diseases globally and emerging evidence demonstrates the bidirectional association between the two diseases. Direct-acting antivirals (DAAs) for HCV have a high treatment success rate and can significantly reduce the risks of short and long-term complications of HCV infection. However, despite the evidence of the association between diabetes and HCV and the benefits of anti-HCV treatment, previously published guidelines did not focus on the universal HCV screening for patients with diabetes and their subsequent management once confirmed as having HCV viremia. Nonetheless, screening for HCV among patients with diabetes will contribute to the eradication of HCV infection. Thus, the three major Taiwan medical associations of diabetes and liver diseases endorsed a total of 14 experts in the fields of gastroenterology, hepatology, diabetology, and epidemiology to convene and formulate a consensus statement on HCV screening and management among patients with diabetes. Based on recent studies and guidelines as well as from real-world clinical experiences, the Taiwan experts reached a consensus that provides a straightforward approach to HCV screening, treatment, and monitoring of patients with diabetes.

Abstract
Treating hepatitis C virus (HCV) in pregnancy would address HCV during prenatal care and potentially reduce the risk of vertical transmission. Response-guided therapy could provide a means to individualize and the reduce duration of HCV treatment during pregnancy. Data from a 27-year-old woman indicated that, pretreatment, HCV was stable and that it dropped in a biphasic manner during sofosbuvir/velpatasvir therapy, reaching target not detected at time of delivery-16 days post-initiation of therapy. Mathematical modeling of measured HCV at days 0, 7, and 14 predicted that cure could have been achieved after 7 weeks of sofosbuvir/velpatasvir, reducing the duration of therapy by 5 weeks.

Abstract
Long-acting agents hold significant promise for treating and preventing common illnesses, including infections. Pharmacokinetic and safety data during pregnancy and lactation are often unavailable for new drugs; these data are vital to facilitate optimal drug use by pregnant and lactating women and women who may conceive. In this commentary, we summarize the circumstances in which pregnant and lactating women are likely to use and benefit from long-acting agents. We focus on long-acting formulations of small molecules (rather than biologics such as monoclonal antibodies) and on several infections of global importance (human immunodeficiency virus, tuberculosis, malaria, and hepatitis C). We discuss pregnancy pharmacokinetic/pharmacodynamic and potential safety and efficacy considerations pertaining to the use of long-acting agents in pregnancy and lactation. Finally, we summarize existing preclinical and pregnancy pharmacokinetic data that are available (or expected in the near future) for several agents that are under development or approved, and how key research gaps may be addressed.

Abstract
INTRODUCTION Direct-Acting Antiviral Agents (DAAs) provide safer, efficacious, tolerable, and curative therapy for women with hepatitis C. Their preferred safety and efficacy profile make them potential therapies for the elimination of perinatal transmission of hepatitis C virus (HCV). However, DAAs are not currently recommended for use during pregnancy due to limited pharmacokinetic and safety data. AREAS COVERED This review covers the different DAA drug combinations, the available data on their pharmacodynamic and pharmacokinetic properties, how the physiology in pregnancy can potentially affect DAA drug disposition, known drug-drug interactions with DAAs, and available and planned epidemiological and pharmacokinetic studies on DAA use during pregnancy. Although no large randomized clinical trials or prospective cohort studies involving DAAs have been completed in pregnancy, the currently available studies demonstrate no significant changes in pharmacokinetics, and no major safety concerns in women with hepatitis C. EXPERT OPINION Initial pharmacokinetic and safety data suggest that DAAs have high efficacy and a low risk of adverse events during pregnancy. As more pharmacokinetic and epidemiologic data become available, DAAs could become a preferred option for treating HCV during pregnancy and elimination of perinatal transmission of hepatitis C virus.

Abstract
OBJECTIVE This is a quality improvement project to determine the best process to identify and address gaps in care for perinatal patients in receiving appropriate hepatitis C virus (HCV) testing and treatment across the largest health system in Maine. STUDY DESIGN We reviewed electronic medical record data between October 1, 2015, and February 1, 2020, to investigate rates of HCV testing and treatment among 916 perinatal patients with opioid use disorder across 8 hospitals using a "cascade of care" framework, a model used previously to identify gaps in care and treatment of chronic diseases. MAIN OUTCOME MEASURE We examined HCV testing and treatment rates along the cascade of care and patient characteristics associated with HCV antibody testing and treatment, separately, using log binomial regression models. Models were adjusted for age, residential distance to medical center, psychiatric diagnosis, and opioid agonist therapy at delivery. RESULTS Of pregnant patients eligible for screening, 64% (582/916) received HCV antibody testing. Of 136 patients with active HCV infection, 32% (n = 43) received a referral for treatment, 21% (n = 28) were treated, and 13% (n = 18) achieved sustained virologic response. In the adjusted regression models, only opioid agonist therapy was associated with HCV antibody testing (adjusted risk ratio, 1.31; 95% confidence interval, 1.18-1.46), and no factors were significantly associated with receipt of treatment among HCV viremic patients. CONCLUSION Low referral and treatment rates signify the need for quality improvement interventions to improve coordination of care between multiple disciplines and practice settings to increase access to HCV treatment.

Abstract
Data on sofosbuvir-based therapy for pregnant women and infant with severe chronic hepatitis C (CHC) are lacking. Two late pregnant women and one female infant with severe CHC were enrolled for treatment. Pregnant women 1 and 2 and infant 3 were 30, 33, and 1.2 years old, respectively; the gestational ages of pregnant women 1 and 2 were 31 and 26 weeks, respectively. Notably, pregnant women 1 and 2 and infant 3 had hepatitis C virus (HCV) RNA levels of 139000, 198000, and 8450000 IU/ml; alanine aminotransferase levels of 420, 781, and 220 U/L; and received sofosbuvir/ledipasvir, sofosbuvir/velpatasvir, and sofosbuvir/ledipasvir for 12 weeks, respectively. All three patients were safely cured with favorable tolerance, and two newborns were both breastfeeding and were consistently negative for the anti-HCV antibody during the one-year follow-up after birth. Additionally, two newborns and infant 3 had normal growth parameters during the follow-up year one. In conclusion, this case series study found that sofosbuvir-based therapy for pregnant women and infant with severe CHC is safe and effective. The data may fill the gap and provide evidence of the use of sofosbuvir-based therapy as a reference when similar severe CHC situations are encountered during clinical practice.

Abstract
Viral hepatitis is one of the emerging public health problems, which urgently needs special attention. The disease has a varied presentation at the time of diagnosis, and it can progress from an accidental finding to life-threatening conditions like liver cirrhosis. It belongs to the rare group of diseases that can cause chronic inflammation inside the body, and it can have a delayed presentation. It contributes substantially to the global burden on healthcare. In terms of mortality, the burden due to viral hepatitis is similar to that of HIV and tuberculosis. It is among the major global public health challenges along with other communicable diseases, such as HIV, malaria, and tuberculosis; the major difference is that there are very limited preventive models in place for viral hepatitis, especially in developing countries like India. With limited resources for diagnosis and treatment, varied levels of presentation, and a rapidly increasing burden, it can become the next silent pandemic. In the current review, the authors aimed to compile the available global strategies for combating hepatitis, protocols available for disease surveillance, and the salient points from the national program for hepatitis control in India [National Viral Hepatitis Control Program (NVHCP)], and propose some recommendations. Ensuring a health facility equipped with a rapid diagnostic kit for screening, proper lab for the confirmation, robust Health Management Information System (HMIS) portal for the data management, and organizing regular workshops for physicians and lab technicians are some of the recommendations that we put forward.

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
Hepatitis C virus infection (HCV) is a global health problem affecting >71 million people worldwide with chronic hepatitis C, 40% reproductive age group, and 8% pregnant women. Intravenous drug abuse, multi-transfusions are major risk factors in adults, while vertical transmission in pediatric population. It commonly presents as a chronic liver disease, has higher risk of liver cirrhosis and even progression to hepatocellular carcinoma. Therefore, proper screening of high-risk populations including pregnancy is recommended. All diagnosed chronic hepatitis C cases should be treated with directly acting anti-virals (DAAs) including pre-conception which has a cure rate of >95%. This would reduce the disease burden, vertical transmission, and disability associated. However, no DAAs regimens recommendation till date due to lack of evidence on adverse fetal outcomes and are concerned about the pharmacokinetic effect regarding physiological changes during pregnancy. Therefore, in this review, we have tried to explore the possible use of DAAs regimens and their safety issues during pregnancy, and possible consideration of few pan-genotypic regimens in the late 2nd and early 3rd trimester. This would not only prevent vertical transmission and decrease disease burden but also help to meet the WHO 2030 target of HCV elimination as a major public health problem.

Abstract
Hepatitis C virus (HCV) is a global health concern associated with significant morbidity and mortality. Before the approval of second-generation direct-acting antiviral agents (DAAs), interferon therapy and liver transplantation constituted the mainstay of treatment. The introduction of well-tolerated oral DAAs in late 2013 has revolutionized HCV management with over 95% cure rates. The predominance of HCV-related liver transplantations has declined following the widespread approval of DAAs. Despite the unparallel efficacy observed among these novel therapies, pharmaceutical costs continue to limit equitable access to healthcare and likely contribute to the differential HCV infection rates observed globally. To reduce the burden of disease worldwide, essential agenda items for all countries must include the prioritization of integrated care models and access to DAAs therapies. Through transparent negotiations with the pharmaceutical industry, the consideration for compassionate release of medications to promote equitable division of care is paramount. Here we provide a literature review of HCV, changes in epidemiologic trends, access issues for current therapies, and global inequities in disease burden.

Abstract
BACKGROUND There are no national data on hepatitis C virus awareness and burden among pregnant women to justify its routine screening. OBJECTIVES To investigate awareness, seroprevalence and risk factors for hepatitis C virus infection among pregnant women in Nigeria. METHODS A total of 159 pregnant women from antenatal clinics across six geopolitical zones in Nigeria consented to anti-hepatitis C virus testing which was confirmed using polymerase chain reaction technique. Confirmed hepatitis C virus positive women were further tested for hepatitis B and HIV. Participants were evaluated for risk factors for hepatitis C virus. Odds ratios, adjusted odds ratios, and their 95% confidence intervals (CIs) were determined, and p-values of <0.05 were considered significant. RESULTS Of 159 participants, 77 (48.4%; 95% confidence interval = 38.2%-60.5%) were aware of hepatitis C virus infection and awareness of hepatitis C virus was associated with young age (odds ratio = 2.21; 95% confidence interval = 1.16-4.21), high educational level (odds ratio = 3.29; 95% confidence interval = 1.63-6.64), and participants' occupation (odds ratio = 0.51; 95% confidence interval = 0.26-0.99). In multivariable logistic regression, adjusted for confounders, the association between awareness of hepatitis C virus and participants' young age (adjusted odds ratio = 1.60; 95% confidence interval = 1.09-2.35; p = 0.018) and high educational level (adjusted odds ratio = 1.48; 95% confidence interval = 1.17-1.86; p = 0.001) remained significant. Hepatitis C virus seroprevalence was found to be 1.3% (95% confidence interval = 0.2%-4.5%). All (100.0%, 95% confidence interval = 12.1%-100.0%) the hepatitis C virus-positive participants and 99 (63.1%, 95% confidence interval = 51.3%-76.8%) hepatitis C virus-negative participants had identifiable hepatitis C virus risk factors. Dual seropositivity of anti-hepatitis C virus/anti-HIV and anti-hepatitis C virus/hepatitis B surface antigen each accounted for 0.6%. The most identified risk factors were multiple sexual partners (15.7%), shared needles (13.8%), and blood transfusion (11.3%). There was no significant association between the risk factors and hepatitis C virus positive status. CONCLUSION Awareness of hepatitis C virus infection among pregnant women in Nigeria is low and those aware are positively influenced by young age and high educational level. The prevalence of hepatitis C virus infection is high and provides preliminary evidence to justify antenatal routine screening.

Abstract
BACKGROUND: There is evidence that barriers exist for the initiation of direct-acting antiviral (DAA) treatment for hepatitis C virus (HCV) for those with substance use disorders (SUDs). However, real world clinical evidence of DAA treatment initiation following receipt of a prescription and continuation among those with SUDs and HCV is lacking. OBJECTIVES: To (1) compare HCV treatment initiation (prescription fill) rates and early discontinuation rates between HCV-infected patients with and without SUDs in the DAA era, and (2) identify patient-level factors associated with HCV treatment initiation and early discontinuation in patients with SUDs. METHODS: A retrospective cohort analysis of the MarketScan databases (January 2012-December 2018) was conducted for newly diagnosed treatment naïve HCV-infected patients (age ≥ 18) with and without SUDs. We used multivariable Cox regression to estimate adjusted hazard ratios (aHRs) with 95% confidence intervals of treatment initiation and early discontinuation in those with SUDs versus those without. RESULTS: We identified a total of 29,228 newly diagnosed HCV-infected patients (6,385 with SUDs and 22,843 without SUDs). Overall, DAA treatment initiation for patients with SUDs was significantly lower than that for those without SUDs (24% vs 34%; P < 0.01). After adjusting for demographics and clinical characteristics, patients with SUDs were less likely to initiate DAA treatments than those without SUDs (aHR, 0.87 [0.82-0.92]). There was no difference in discontinuation of DAA treatment between those with and without SUDs (4% vs 3%: aHR, 1.13 [0.81-1.60]). Among patients with SUDs (n = 6,385), lower rates of initiating DAA treatment was associated with younger age, and comorbidities including alcoholic liver disease (ALD; aHR, 0.44 [0.33-0.57), chronic kidney disease (CKD) (aHR, 0.52 [0.36-0.75]), and hepatitis B virus (HBV; aHR, 0.64 [0.44-0.92]). DAA treatment discontinuation was associated with younger age, ribavirin (RBV) therapy (aHR, 3.78 [2.21-6.47]), and cirrhosis diagnosis (aHR, 2.42 [1.21-4.84]) but not SUD treatment (aHR, 0.68 [0.34-1.34]). CONCLUSIONS: HCV-infected patients with SUDs had significantly lower treatment initiation rates, especially in young females and those with ALD, CKD, and HBV. No difference was found in DAA discontinuation. However, younger patients with RBV treatment and/or cirrhosis were more likely to stop treatment. Interventions directed towards these groups are needed to enhance DAA initiation and treatment maintenance among HCV-infected patients with SUDs. DISCLOSURES: Research reported in this publication was supported in part by the National Institute on Drug Abuse of the National Institutes of Health under award number K01DA045618 (to Park). The other authors have nothing to disclose that may present a potential conflict of interest.

Abstract
OBJECTIVE This revised guideline provides updated information for the care of women with chronic viral infections who require intrauterine fetal diagnostic testing. TARGET POPULATION Women with chronic viral infections who are pregnant or planning a pregnancy. OPTIONS Non-invasive screening tests for diagnosis: maternal serum placental analytes with or without nuchal translucency, sonography, maternal serum cell-free placental DNA; and intrauterine fetal diagnostic testing: amniocentesis, chorionic villus sampling, cordocentesis. OUTCOMES The recommendations in this guideline have the potential to decrease or eliminate morbidity and mortality in women with chronic viral infections and their infants, which is associated with significant health and economic outcomes. EVIDENCE Published literature was retrieved through searches of PubMed, guidelines of national societies (Society of Obstetricians and Gynaecologists of Canada, American College of Obstetricians and Gynecologists, Society for Maternal-Fetal Medicine, other international societies), and the Cochrane Library using appropriate controlled vocabulary (amniocentesis, chorionic villus sampling, cordocentesis, procedure pregnancy loss risk, viral vertical transmission, fetal and neonatal infection) and keywords (maternal infection or exposure, hepatitis B, hepatitis C, human immunodeficiency virus). Results were restricted to systematic reviews, randomized controlled trials or controlled clinical trials (if available), and observational case-control studies or case series from 2012 to 2019 published in English or French. Studies from 1966 to 2002 were previously reviewed in the SOGC guideline No. 123: Amniocentesis and Women with Hepatitis B, Hepatitis C, or Human Immunodeficiency Virus, and those from 2002 to 2012 were previously reviewed in the SOGC guideline No. 309: Prenatal Invasive Procedures in Women With Hepatitis B, Hepatitis C, and/or Human Immunodeficiency Virus Infections. Updated literature searches were completed regularly through August 2019 and were incorporated into this guideline. VALIDATION METHODS The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. See online Appendix A (Tables A1 for definitions and A2 for interpretations of strong and weak recommendations). INTENDED AUDIENCE The intended users are maternity care providers and women with chronic viral infections. This guideline provides information to educate and counsel these women, and to offer them reproductive options. RECOMMENDATIONS (GRADE RATINGS IN PARENTHESES).

Abstract
The prevalence of Hepatitis C virus infection (HCV), a leading cause of chronic liver disease worldwide, is rising in the United States (US) and other high-income countries, especially among youth and young adults. This surge in cases is closely associated with the opioid crisis and intravenous drug use (IVDU). However, its prevalence and impact on the adolescent population have not been thoroughly studied and therefore is poorly understood. The pediatric population tends to have milder liver disease and progression when compared to adults; however, there is a risk of developing liver cirrhosis, in addition to facing decreased quality of life and stigmatization from the disease. The recent approval of direct-acting antiviral (DAA) regimens for all HCV genotypes and age greater than 3 years has revolutionized its management. Therapy has shifted from the prolonged interferon-based regimens, to shorter duration, once daily oral pills that are highly effective, curative and with fewer side effects. Therapy is now indicated for all adolescents with hepatitis C virus infection, regardless of stage of liver disease, recent IVDU, or coinfection with HIV, therefore eliminating a lifetime risk of chronic liver disease, cirrhosis and hepatocarcinoma. Nonetheless, adolescents are rarely tested or treated for hepatitis C infection, and very few adolescents complete therapy. Implementation of point of care (POC) testing of high-risk youth at drug treatment centers or other juvenile facilities may be a good strategy to increase testing, diagnosis and therapy. This review article aims to educate pediatricians and other primary care providers to help decrease the existing knowledge gap on the subject.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection is still one of the leading causes of chronic liver disease, with chronically infected making up approximately 1% of the global population. Of those infected, 70% (55-85%) will develop chronic HCV infection. Chronic HCV infection causes substantial morbidity and mortality, with complications including cirrhosis, end-stage liver disease, hepatocellular carcinoma, and eventually death. OBJECTIVE Therapeutic options for chronic HCV infection have evolved dramatically since 2014, with a translation from pegylated interferon and ribavirin (associated with suboptimal cure and high treatment-related toxicity) to oral direct-acting antiviral treatment. There are four classes of direct-acting antivirals which differ by their mechanism of action and therapeutic target. They are all pointed to proteins that form the cytoplasmic viral replication complex. Multiple studies have demonstrated that direct-acting antiviral therapy is extremely well tolerated, highly efficacious, with few side effects. METHODS We performed an indexed MEDLINE search with keywords regarding specific direct-acting antiviral regimes and their pharmacokinetics, drug-drug interactions, and metabolism in specific settings of pregnancy, lactation, liver cirrhosis, liver transplantation and HCC risk, kidney failure and kidney transplantation. RESULTS We present a comprehensive overview of specific direct-acting antiviral metabolism and drug-drug interaction issues in different settings. CONCLUSION Despite its complex pharmacokinetics and the possibility of drug-drug interactions, direct-acting antivirals are highly efficacious in providing viral clearance, which is an obvious advantage compared to possible interactions or side effects. They should be administered cautiously in patients with other comorbidities, and with tight control of immunosuppressive therapy.

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

Drug related adverse pregnancy outcomes at a tertiary care hospital from the foothills of Himalayas: A Prospective observational study. J Family Med Prim Care 2021; 10:4176-4181. [PMID: 35136785 PMCID: PMC8797097 DOI: 10.4103/jfmpc.jfmpc_211_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2021] [Revised: 06/22/2021] [Accepted: 07/15/2021] [Indexed: 11/09/2022] Open
Abstract
Context and Aim: Safety of drug usage during pregnancy is of utmost importance. Unrestricted usage of drugs may lead to undesirable and unpredictable pregnancy outcomes. This study was designed to detect drug-related adverse pregnancy outcomes, perform prescription audit and develop a pregnancy drug registry. Methods and Materials: A prospective observational study was conducted at a tertiary care hospital in northern India. Pregnant females attending antenatal clinic, irrespective of their duration of pregnancy were included in the study over a period of 1 year. The participants were followed up monthly during their pregnancy till the pregnancy outcome. Adverse pregnancy outcomes were evaluated and causality assessment was done using the WHO-UMC scale. Statistical Analysis: Descriptive and inferential statistical tools were used for appropriate variables. Regression model was used to establish relationship between factors proposed to be responsible for adverse pregnancy outcomes. Presence of adverse pregnancy outcome was used as an independent variable. Microsoft Excel and Strata (version 12) were used for statistical analysis. Results: A total 326 pregnant women were screened out of which 305 were included in the final analysis. Mean age of participants was 27.82 (±4.51) years. Pre-existing comorbidities were present in 4.26% of participants. Average number of drugs per participant was 6.32 (±1.94). Most drugs prescribed to participants were from FDA category B (49.23%) and category A (33.60%). Mean ADR reported per patient was 1.16 (±1.18) with involvement of musculoskeletal (56.42%) and gastrointestinal (7.16%) being most frequent. Adverse pregnancy outcomes were reported in 25 participants among which IUGR (24%) followed by IUD (20%) and ectopic pregnancy (16%) were most frequently observed. Multivariate logistic regression showed number of comorbidities (P = 0.037) and number of drugs consumed during pregnancy (P = 0.02) to be statistically significantly associated with occurrence of adverse pregnancy outcome. Conclusions: Pregnancy registries have been instrumental in detection of signals for further research in drug-related adverse outcomes. Inappropriate usage of drugs has been shown to be associated with adverse pregnancy outcomes. Our study warrants need for further well-designed studies on adverse pregnancy outcomes in larger patient populations.

Abstract
Background Currently no effective antiviral therapy has been found to treat COVID-19. The aim of this trial was to assess if the addition of sofosbuvir and daclatasvir improved clinical outcomes in patients with moderate or severe COVID-19. Methods This was an open-label, multicentre, randomized controlled clinical trial in adults with moderate or severe COVID-19 admitted to four university hospitals in Iran. Patients were randomized into a treatment arm receiving sofosbuvir and daclatasvir plus standard care, or a control arm receiving standard care alone. The primary endpoint was clinical recovery within 14 days of treatment. The study is registered with IRCT.ir under registration number IRCT20200128046294N2. Results Between 26 March and 26 April 2020, 66 patients were recruited and allocated to either the treatment arm (n = 33) or the control arm (n = 33). Clinical recovery within 14 days was achieved by 29/33 (88%) in the treatment arm and 22/33 (67%) in the control arm (P = 0.076). The treatment arm had a significantly shorter median duration of hospitalization [6 days (IQR 4–8)] than the control group [8 days (IQR 5–13)]; P = 0.029. Cumulative incidence of hospital discharge was significantly higher in the treatment arm versus the control (Gray’s P = 0.041). Three patients died in the treatment arm and five in the control arm. No serious adverse events were reported. Conclusions The addition of sofosbuvir and daclatasvir to standard care significantly reduced the duration of hospital stay compared with standard care alone. Although fewer deaths were observed in the treatment arm, this was not statistically significant. Conducting larger scale trials seems prudent.

Abstract
Hepatitis C is a global public health threat. The introduction of direct-acting antivirals (DAAs) brings the prospect of curing the 71 million people living with the disease, dramatically changing the landscape of hepatitis C. The World Health Organization developed a roadmap for the elimination and cure of hepatitis C by 2030 with a clear goal with measurable targets. However, there is a lack of a well-defined strategy to tackle the hepatitis C virus (HCV) problem in children and adolescents vis-à-vis the adult population. Hepatitis C in children and adolescents can be addressed as part of a national policy for elimination in the whole population, namely macroelimination, or could be fragmented into a microelimination approach targeting the high-risk population groups. Children born to HCV-infected mothers, adolescents who are injecting drugs, migrants, and those suffering from inherited blood diseases are important target populations. After the U.S. Food and Drug Administration approval for the use of DAAs in children aged 3 years and above, evidence from clinical trials and real-world experience was accumulated using brand and generic medicines, with sustained virological response rates exceeding 95%. The evidence created should guide policies on the management of hepatitis C in children and adolescents. There are many challenges in managing HCV in this left-behind marginalized population. The lack of awareness and epidemiological data, consent age, prohibitive prices of medicines, and absence of policies on access to diagnostics, treatment, and linkage to care are among the many barriers to service delivery that should be addressed to achieve the elimination goal by 2030.

Abstract
Hepatitis C virus (HCV) infection is a silent killer that leads to rapid progression of liver cirrhosis and hepatocellular carcinoma (HCC). High prevalence of HCV infection has been reported in Taiwan, especially in high-risk populations including people who inject drugs (PWID) and patients requiring dialysis. Besides, certain populations merit special considerations due to suboptimal outcome, potential drug-drug interaction, or possible side effect. Therefore, in the second part of this 2-part consensus, the Taiwan Association for the Study of the Liver (TASL) proposes the treatment recommendations for the special population in order to serve as guidance to optimizing the outcome in the direct-acting antiviral (DAA) era. Special populations include patients with acute or recent HCV infection, previous DAA failure, chronic kidney disease, decompensated cirrhosis, HCC, liver and other solid organ transplantations, receiving an HCV viremic organ, hepatitis B virus (HBV) and HCV dual infection, HCV and human immunodeficiency virus (HIV) coinfection, active tuberculosis infection, PWID, bleeding disorders and hemoglobinopathies, children and adolescents, and pregnancy. Moreover, future perspectives regarding the management of hepatitis C are also discussed and summarized in this consensus statement.

Abstract
INTRODUCTION Mother-to-child transmission (MTCT) of HIV is thought to account for over 90% of new pediatric infections, and is associated with poor maternal and fetal outcomes. As such ensuring further reduction in MTCT is a priority in HIV treatment and prevention programs. AREAS COVERED This review aims to provide a comprehensive update on the pharmacokinetics of recently approved antiretroviral drugs and novel drug formulations and delivery systems. Alongside recent recommendations for dose adjustments, and an overview of the implications of co-infections on the pharmacokinetics of antiretrovirals relevant to pregnant HIV positive patients. Additionally, potential opportunities to progress pharmacokinetic research of new treatments in this population are highlighted. EXPERT OPINION In order to improve our understanding of how to provide safe and effective treatment to HIV positive pregnant women, further work is required to enable their inclusion in early stages of clinical trials. Incentives must be created for this research, in the form of additional investment by key stakeholders and regulatory agencies. Furthermore, as the incidence of MTCT is reduced globally there is a need to conduct long-term pharmacovigilance studies in uninfected children exposed to HIV and antiretrovirals in utero, in order to determine the safest and most effective antiretroviral therapies.

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