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
BACKGROUND Hepatitis C virus (HCV) infection is a global public health problem and also generates a significant case load in children and adolescents. With the introduction of directly acting antivirals (DAA), the treatment and care of HCV-infected patients have progressed significantly. The available treatment options in children are limited, and this review aims to provide an overview of treatment of HCV infection in children and adolescents with the current available DAA regimens. DATA SOURCES This comprehensive review was undertaken after searching the PubMed/Medline and Embase databases for the available up-to-date literature on pediatric HCV infection and treatment using hepatitis C virus infection/HCV, directly acting antivirals/DAA, natural history, treatment, pediatrics, children, and adolescents as keywords. RESULTS Combination therapies with highly effective DAA regimes, such as sofosbuvir/ledipasvir, sofosbuvir/velpatasvir, glecaprevir/pibrentasvir, sofosbuvir/daclatasvir, sofosbuvir/ribavirin and others, are available for use in children. Most of the DAA regimens have either received or are pending to receive regulatory approval by different medical/drug agencies for use in children and adolescents. Pan-genotypic regimens are also available in children and adolescents, and these regimens can be used while skipping genotype testing. CONCLUSION The literature on different DAA regimens for use in children shows that these regimens have higher cure rates with minimal side effects and shorter duration of therapy.

Abstract
BACKGROUND Chronic hepatitis C virus (HCV) infection represents a crucial health problem in children that greatly influences their quality of life. Many efforts have been directed toward investing in effective drugs with a high safety profile and oral administration for better compliance. OBJECTIVES This study aims to assess the safety of a fixed-dose combination of ledipasvir/sofosbuvir plus drug efficacy and sustained virologic response (SVR) at 12 weeks after treatment discontinuation. METHOD One tablet (90 mg ledipasvir, 400 mg sofosbuvir) was administered to treatment-naïve children aged 12-18 years weighing at least 35 kg with chronic HCV infection for 6 months, genotype 4. Patients were divided into 2 groups, (1) without comorbidities (24 patients) and (2) with comorbidities (26 patients). RESULTS At the end of the therapy, all patients (100%) had SVR and a significant reduction of liver enzymes with mild tolerable side effects. CONCLUSION Ledipasvir/sofosbuvir fixed-dose combination is a safe and highly effective therapeutic option in Egyptian children aged ≥ 12 years, with chronic HCV infection, genotype 4, either without or with comorbidities.

Abstract
AIM The aim of this study was to describe the epidemiological and clinical characteristics in children with either chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infection in Denmark. METHODS In this observational study, children and adolescents with either chronic HBV or HCV infection followed at the largest paediatric departments in Denmark between 2001 and 2013 were included. Data collection included as well epidemiological data as clinical data like virus genotype, viral load, serological markers, liver biochemistry, liver elastography and histology if available. RESULTS The study included 131 children. None of the patients had decreased liver function or end-stage liver disease during follow-up. Ten of the 18 children who underwent liver biopsy had signs of fibrosis. Thirteen (11%) children with HBV and one (7%) child with HCV received treatment. Different indications and different treatment regimens were used. CONCLUSION This study confirms that chronic HBV and HCV infections are often mild diseases during childhood. Nevertheless, children are at higher risk of serious liver disease early in life because of the early time of infection and probably also because of the high viral loads.

Abstract
In 1989, a collaboration between the Centers for Disease Control (CDC) and a California biotechnology company identified the hepatitis C virus (HCV, formerly known as non-A, non-B hepatitis virus) as the causative agent in the epidemic of silent posttransfusion hepatitis resulting in cirrhosis. We now know that, the HCV genome is a 9.6 kb positive, single-stranded RNA. A single open reading frame encodes a 3011 amino acid residue polyprotein that undergoes proteolysis to yield 10 individual gene products, consisting of 3 structural proteins (core and envelope glycoproteins E1 and E2) and 7 nonstructural (NS) proteins (p7, NS2, NS3, NS4A, NS4B, NS5A, and NS5B), which participate in posttranslational proteolytic processing and replication of HCV genetic material. Less than 25 years later, a new class of medications, known as direct-acting antivirals (DAAs) which target these proteins, were introduced to treat HCV infection. These highly effective antiviral agents are now approved for use in children as young as 3 years of age and have demonstrated sustained virologic responses exceeding 90% in most genotypes. Although tremendous scientific progress has been made, the incidence of acute HCV infections has increased by 4-fold since 2005, compounded in the last decade by a surge in opioid and intravenous drug use. Unfortunately, awareness of this deadly hepatotropic virus among members of the lay public remains limited. Patient education, advocacy, and counseling must, therefore, complement the availability of curative treatments against HCV infection if this virus is to be eradicated.

Abstract
BACKGROUND Maternal HIV coinfection is a key factor for mother-to-child transmission (MTCT) of HCV. However, data about HCV MTCT in HIV/HCV-coinfected pregnant women on combined antiretroviral treatment (ART) are scarce. This study assessed the HCV MTCT rate in the Madrid Cohort of HIV-infected women. METHODS Retrospective study within the Madrid Cohort of HIV-infected pregnant women (2000-2012). Epidemiological, clinical and treatment related variables were analysed for the mother and infant pairs. HCV MTCT rate was determined. RESULTS Three hundred thirty-nine HIV/HCV-coinfected women and their exposed infants were recorded. A total of 227 (67%) paired mother-children had available data of HCV follow-up and were included for the analysis. Sixteen children (rate 7.0%, 95%CI 3.7-10.4%) were HCV infected by 18 months of age, none of them coinfected with HIV. HIV/HCV-coinfected pregnant women were mostly of Spanish origin with a background of previous injection drug use. HCV-genotype 1 was predominant. The characteristics of mothers that transmitted HCV were similar to those that did not transmit HCV with respect to sociodemographic and clinical features. A high rate (50%) of preterm deliveries was observed. Infants infected with HCV were similar at birth in weight, length and head circumference than those uninfected. CONCLUSION MTCT rates of HCV among HIV/HCV-coinfected women on ART within the Madrid cohort were lower than previously described. However, rates are still significant and strategies to eliminate any HCV transmission from mother to child are needed.

Abstract
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.

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
Hepatitis C virus (HCV) infection is a major cause of chronic liver disease and associated morbidity and mortality worldwide. Short-course, oral, curative, direct-acting antiviral regimens have transformed treatment for HCV infection. Since the 2016 launch of the first global strategy towards elimination of viral hepatitis as a public health threat by 2030, the predominant focus of the global response has been on the treatment of adults, who bear the greatest burden of morbidity and mortality of HCV-related chronic liver disease. Compared with adults, there has been little attention paid to addressing the response to HCV in children and adolescents, in part because of the scarcity of data to inform specific paediatric management practices and policy. In this Series paper, we summarise knowledge on the epidemiology, natural history, and treatment of chronic HCV infection in adolescents and children, and we highlight key differences from infection acquired in adulthood. The estimated global prevalence and burden of HCV infection in children aged 1-19 years is 0·15%, corresponding to 3·5 million people (95% CI 3·1-3·9 million). HCV infection is usually asymptomatic during childhood, and cirrhosis and hepatocellular carcinoma are rare. Sofosbuvir with ledipasvir and sofosbuvir with ribavirin have received regulatory approval and guidelines recommend their use in adolescents aged 12 years and older with HCV infection. In April, 2019, glecaprevir with pibrentasvir also received regulatory approval for adolescents aged 12-17 years. Key actions to address the current policy gaps and achieve treatment scale-up that is comparable to that in adults include: establishment of a campaign on access to testing and treatment that is targeted at children and adolescents; fast-track evaluation of pan-genotypic regimens; and accelerated approval of paediatric formulations. Research gaps that need to be addressed include: age-specific prevalence studies of HCV viraemia in priority countries; further validation of non-invasive tests for staging of liver disease in children; and establishment of paediatric treatment registries and international consortia to promote collaborative research agendas.

Abstract
BACKGROUND Symptomatic bradycardia has been reported in adults treated for chronic hepatitis C using sofosbuvir based regimens. AIM We studied the cardiac safety of sofosbuvir/ledipasvir in Egyptian children, treated for chronic hepatitis C. METHODS The study included 40 hepatitis C virus infected children and adolescents 12-17 years old, using the combination of sofosbuvir (400 mg)/ledipasvir (90 mg) in a single oral tablet (Harvoni) taken daily for 12 weeks. All subjects underwent a baseline standard 12-lead surface Electrocardiography that was repeated at 4 and 12 weeks of therapy. Electrocardiography parameters (Heart Rate, RR interval, PR interval, QRS, QT interval, corrected QT interval, QT dispersion, JT interval, corrected JT interval, JT dispersion, Tpeak-Tend interval) were compared at the 3 different time points during antiviral therapy. RESULTS No symptoms related to the cardiovascular system were reported during treatment. There were no cases of symptomatic bradycardia/syncope. Heart rate was noted to be significantly lower and RR and QT intervals were significantly longer in the baseline electrocardiography. Heart rate was significantly lower and RR interval was significantly longer in patients with higher viral load. CONCLUSION No adverse cardiovascular events were observed in this group of HCV infected children and adolescents treated with sofosbuvir/ledipasvir. None of the patients developed bradyarrhythmias during treatment.

Abstract
Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections represent a major global public health and economic burden, with an estimated 257 million and 71 million people, respectively, having chronic infection worldwide. The natural history of HBV and HCV in children depends on age at time of infection, mode of acquisition, ethnicity, and genotype. Most children infected perinatally or vertically remain asymptomatic but are at uniquely higher risk of developing chronic viral hepatitis, progressing to liver cirrhosis and hepatocellular carcinoma (HCC), hence classifying HBV and HCV as oncoviruses. This article discusses the epidemiology, virology, immunobiology, prevention, clinical manifestations, evaluation, and the advances in treatment of hepatitis B and C in children.

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
PURPOSE OF REVIEW This review highlights key studies and recently published data, policies, and recommendations related to hepatitis C virus (HCV) epidemiology, transmission, and treatment. RECENT FINDINGS HCV is a leading cause of liver-related deaths, cirrhosis, and hepatocellular carcinoma. Since 2011 and accelerating since 2013, new, safe, tolerable, and curative therapies have considerably altered clinical and public health frameworks related to the prevention, control and clinical management of HCV. Nevertheless, there are several populations in the United States that are important to consider because of disparities in HCV prevalence and transmission risk. Adults born during 1945-1965 have an estimated anti-HCV antibody prevalence of ~3%, which is six times higher than among other adults, are often unaware of their infections, and are at increased risk of having HCV-associated morbidity and mortality from decades of chronic infection. Since the early 2000s, increasing incidence of acute HCV infections among young, white, non-urban people who inject drugs have been reported. Despite promising therapeutic advances, significant challenges remain for reducing HCV-associated morbidity and mortality. SUMMARY The high burden of HCV and significant health consequences associated with chronic infection make HCV a critical public health priority. Advances in HCV treatment have created new opportunities for reducing HCV-associated morbidity and mortality. These treatments are safe, well-tolerated, and highly effective; however, benefits cannot be realized without a significant increase in the number of persons tested for HCV so that all chronically infected individuals can be aware of their diagnosis and linked to appropriate clinical care.

Abstract
In the United States, chronic infection with the hepatitis C virus (HCV) affects an estimated 0.1-2% of the pediatric population, who are consequently at risk for major complications, including cirrhosis, hepatocellular carcinoma, and death. The current standard of treatment for chronic hepatitis C (CHC) in children is pegylated-interferon-alpha (PEG-IFN) in combination with ribavirin. PEG-IFN/ribavirin therapy is approved for children ages 3 and older; however, it is often held from use until adulthood because of its extensive list of potential side effects and high likelihood of causing adverse symptoms. While CHC is usually indolent in children and adolescents, immediately treating and curbing the spread of HCV before adulthood is important, as there can be transmission to other individuals via sexual activity and infected females can later vertically transmit the infection during pregnancy, the latter representing the most common means of transmission for children in the United States. The recent development of direct-acting antivirals has shown promising results in clinical trials for use in children and has dramatically increased the rates of sustained virological response in adults while improving side effect profiles as compared to interferon-based treatments. Given the usually indolent course of CHC in children, significant side effects of the currently-approved PEG-IFN/ribavirin therapy, and likely availability of all-oral interferon-free regimens for children within a few years, deferring treatment in clinically-stable children with CHC in anticipation of upcoming superior treatment modalities may be justified.

Abstract
Hepatitis C virus (HCV) infection is a major medical challenge affecting around 200 million people worldwide. The main site of HCV replication is the hepatocytes of the liver. HCV is a positive enveloped RNA virus from the flaviviridae family. Six major HCV genotypes are implicated in the human infection. In developed countries the children are infected mainly through vertical transmission during deliveries, while in developing countries it is still due to horizontal transmission from adults. Minimal nonspecific and brief symptoms are initially found in approximately 15% of children. Acute and chronic HCV infection is diagnosed through the recognition of HCV RNA. The main objective for treatment of chronic HCV is to convert detected HCV viremia to below the detection limit. Children with chronic HCV infection are usually asymptomatic and rarely develop severe liver damage. Therefore, the benefits from current therapies, pegylated-Interferon plus ribavirin, must be weighed against their adverse effects. This combined treatment offers a 50-90% chance of clearing HCV infection according to several studies and on different HCV genotype. Recent direct acting antiviral (DAA) drugs which are well established for adults have not yet been approved for children and young adults below 18 years. The most important field for the prevention of HCV infection in children would be the prevention of perinatal and parenteral transmission. There are areas of focus for new lines of research in pediatric HCV-related disease that can be addressed in the near future.

Abstract
BACKGROUND Vertical transmission of hepatitis C virus (HCV) is the most common route of pediatric HCV infection. Approximately 5% of children born to HCV-infected mothers develop chronic infection. Recommendations employ risk-based HCV testing of pregnant women, and screening children at a young age. This study assesses testing rates of children born to mothers tested HCV-positive in a major US city with a high burden of HCV infection. METHODS HCV surveillance data reported to the Philadelphia Department of Public Health are housed in the Hepatitis Registry. Additional tests, including negative results, were retrospectively collected. HCV data were matched with 2011-2013 birth certificates of children aged ≥20 months to identify mothers tested HCV-positive and screened children. The observed perinatal HCV seropositivity rate was compared to the expected rate (5%). RESULTS A total of 8119 females aged 12-54 years tested HCV-positive and in the Hepatitis Registry. Of these, 500 (5%) had delivered ≥1 child, accounting for 537 (1%) of the 55 623 children born in Philadelphia during the study period. Eighty-four (16%) of these children had HCV testing; 4 (1% of the total) were confirmed cases. Twenty-three additional children are expected to have chronic HCV infection, but were not identified by 20 months of age. CONCLUSIONS These findings illustrate that a significant number of women giving birth in Philadelphia test positive for HCV and that most of their at-risk children remain untested. To successfully identify all HCV-infected children and integrate them into HCV-specific care, practices for HCV screening of pregnant women and their children should be improved.

Abstract
AIM An estimated 1.1% of Australian adults are infected with hepatitis C virus (HCV). Many develop chronic liver disease, and some develop liver failure or hepatocellular carcinoma. HCV infection in Australian children is poorly defined. We aimed to determine the reported incidence, clinical and epidemiological features of newly diagnosed HCV infection in Australian children presenting to paediatricians. METHODS We undertook prospective active national surveillance, using the Australian Paediatric Surveillance Unit, of incident HCV cases in children aged <15 years between 1(st) January 2003, and 31(st) December 2007. RESULTS There were 45 confirmed cases of newly diagnosed HCV infection over five years (<1 per 100,000 children aged <15 years per year). Median age at diagnosis was 2.9 years. Positive maternal HCV serostatus was the most frequent reported risk factor for HCV infection in children (40/45). Three children (all aged > 14), were exposed through their own IV drug use. No children were co-infected with HIV and only one child was co-infected with HBV. All children were asymptomatic at diagnosis, although many had minor elevations in liver transaminases. Many clinicians reported difficulties with follow-up. CONCLUSIONS Childhood HCV infection is uncommon in Australia, although our data likely underestimate the incidence. Only a small number of children aged <18 months was identified, despite known perinatal exposure. Opportunistic investigation of children at risk for HCV, improved education regarding vertical transmission for health care providers, and increased coordination of childhood HCV services are required to improve recognition and management of children with HCV.

Abstract
BACKGROUND Optimal therapy for children with chronic hepatitis C is unclear. Two treatment regimens are currently licensed in children. OBJECTIVES To assess the clinical effectiveness and cost-effectiveness of peginterferon alfa-2a (Pegasys®, Roche) and peginterferon alfa-2b [ViraferonPeg®, Merck Sharp & Dohme (MSD)] in combination with ribavirin (RBV), within their licensed indications, for the treatment of chronic hepatitis C virus (HCV) in children and young people aged 3-17 years. DATA SOURCES Twelve electronic bibliographic databases, including The Cochrane Library, MEDLINE and EMBASE, were searched from inception to November 2012. Bibliographies of retrieved papers, key hepatitis C websites and symposia and manufacturers' submissions to the National Institute for Health and Care Excellence were also searched, and clinical experts were contacted. REVIEW METHODS Systematic reviews of clinical effectiveness and cost-effectiveness were conducted, including studies of health-related quality of life (HRQoL), following standard guidelines to ensure methodological rigour. Clinical effectiveness studies were included if they were in children and young people aged 3-17 years with chronic compensated HCV of any severity, including those with human immunodeficiency virus co-infection and those who were treatment naive or had been previously treated. Eligible interventions were peginterferon alfa-2a or peginterferon alfa-2b, each in combination with RBV, compared against best supportive care (BSC) or against each other, and study designs were randomised controlled trials (RCTs) or non-RCTs, or uncontrolled cohort studies. Outcomes included sustained virological response (SVR) and adverse events. Previously published Markov state-transition economic models of chronic HCV in adults were adapted to estimate the cost-effectiveness of peginterferon alfa-2a and -2b (in combination with RBV), compared with BSC and with one another in children. The model extrapolated the impact of SVR on life expectancy, quality-adjusted life expectancy and lifetime costs. Uncertainty was explored through probabilistic and deterministic sensitivity analyses. RESULTS Seven studies [two peginterferon alfa-2a and RBV (Copegus®, Roche), and five peginterferon alfa-2b and RBV (Rebetol®, MSD)] were included in the review of clinical effectiveness. Six were single-arm cohort studies and one was a RCT for which only those data for a single arm met the inclusion criteria. Overall, the studies were relatively small and of generally poor quality. SVR rates ranged from 53% to 66% (peginterferon alfa-2a) and 29% to 75% (peginterferon alfa-2b) (49% to 65% if excluding two studies with very small sample sizes). Rates of non-response and relapse were variable and adverse events were generally mild. No studies of cost-effectiveness or HRQoL in children and young people met the inclusion criteria. HRQoL, utilities and costs of treatment were therefore taken from studies of adults with chronic HCV. From this model, peginterferon alfa (-2a or -2b) in combination with RBV was more effective and had lower lifetime costs than BSC. Peginterferon alfa-2a had slightly lower lifetime costs and higher quality-adjusted life-years than peginterferon alfa-2b; therefore, peginterferon alfa-2b was dominated by peginterferon alfa-2a. Results were robust to changes in the sensitivity analyses. LIMITATIONS There were few good quality studies and parameter data had to be taken from adult studies, which is a limitation of the work. CONCLUSIONS Treatment of children and young people with peginterferon (alfa-2a or -2b) and RBV may be an effective therapy. Results from the independent Markov model suggest that peginterferon (alfa-2a or -2b) in combination with RBV is cost-effective compared with BSC. However, the available evidence is of poor quality. Future research into the impact of these treatments on growth and quality of life in children and young people is recommended. STUDY REGISTRATION This study is registered as PROSPERO CRD42012002743.

Abstract
BACKGROUND To decide when and how to treat children with chronic hepatitis C is an ongoing debate. AIM To compare the outcomes of therapy for children with chronic hepatitis C. METHODS An electronic database assessed clinical trials with sustained virological response rates specified by genotype. The data were extracted according to the therapeutic regimen; interferonα±ribavirin and pegylated interferonα±ribavirin. RESULTS The search sourced 23 peer-reviewed articles which enrolled 934 cases, aged 2-19 years. Sustained virological response rates were significantly higher with the addition of ribavirin to either interferonα or pegylated nterferonα vs. their monotherapies for genotypes 1,2&3 with crude and weighted estimates. The weighted estimate indicated higher sustained virological response rates for those treated with pegylated interferonα+ribavirin vs. interferonα+ribavirin for genotype 1 (50% vs. 40%) and genotypes 2&3 (90% vs. 84%), (odds ratio 1.5, 95% confidence interval 1.2-1.8, and 1.8, 1.2-2.9 respectively). Cases with genotype 4 treated with pegylated interferonα+ribavirin had a lower sustained virological response (41%) vs. genotype 1 (1.4, 1.2-1.8), and vs. genotypes 2&3 (13.5, 10.3-17.9). Some adverse events were significantly higher among cases treated with pegylated interferonα+ribavirin vs. interferonα+ribavirin. CONCLUSIONS Despite the superiority of pegylated interferonα+ribavirin to interferonα+ribavirin for the treatment of chronic hepatitis C among children, the significant higher adverse events along with the modest outcome for genotypes 1&4 render that regimen a suboptimal therapy. These data indicated the need for the future comparison with clinical trials of direct anti-viral drugs for children with chronic hepatitis C.

Abstract
HCV may lead to the development of ESLD in late childhood and, consequently, contributes to the need for liver transplantation. The aim of this study was to examine post-transplant outcomes in HCV-positive pediatric patients with ESLD from any cause and to determine the impact of the PELD scoring system, introduced in February 2002, on post-transplant patient and graft survival. A retrospective analysis of the UNOS database from 1994 to 2010 was performed to assess graft and patient survival in pediatric HCV-seropositive liver transplant recipients. Graft survival and patient survival comparing subjects in the pre-PELD era and post-PELD era were analyzed using Kaplan-Meier statistics. Factors associated with survival were identified using Cox regression analysis. Of 120 pediatric HCV transplant recipients, 80 were transplanted in the pre-PELD era and 40 were transplanted post-PELD. Median serum total bilirubin, INR, and creatinine were 4.8 mg/dL, 1.6, and 0.7 mg/dL in the pre-PELD era vs. 5.5 mg/dL, 1.7, and 0.6 mg/mL, respectively, in the post-PELD era (p NS). One-yr graft survival in the pre-PELD vs. post-PELD era was 65.0% and 89.7%, respectively (p < 0.01); corresponding three-yr graft survival was 57.3% vs. 76.2% (p = 0.04). One-yr patient survival in the pre-PELD vs. post-PELD era was 79.0% and 97.5%, respectively (p < 0.01); corresponding three-yr survival was 79.0% vs. 89.4% (p = 0.17). Twenty-eight patients (23.3%) were retransplanted: 24 (30%) in the pre-PELD era (median time to retransplant 272 days) and four (10%) in the post-PELD era (median time to retransplant 586 days). Early follow-up demonstrates a trend toward improved pediatric HCV liver transplant graft and patient survival in the post-PELD era. Superior outcomes may be attributed to pretransplant factors, improved surgical technique and better treatment options for HCV infection.

The aim of this study was to outline the natural course of vertical HCV infection in a cohort of untreated children, including rate of spontaneous viral clearance, frequency and features of HCV-related autoimmune disorders. Children with vertical HCV infection were prospectively followed from the first month of life with regular clinical and laboratory assessments. Statistical analysis was performed using Prism 5.0. Forty-five children (median age 12 years, interquartile range 6.9-15.5) were studied. Genotype 1 was predominant (53.3 %). Spontaneous viral clearance was achieved by 12 patients (26.7 %) and associated with genotype 3. Alanine-amino-transferase levels were increased in most children in the first 2 years of life with higher values in those who later cleared the infection. All children were asymptomatic for liver disease. Transient elastography (32 patients) showed mild or moderate fibrosis in nine and two cases, respectively. Non-organ-specific autoantibodies were detected in 24 children (53.3 %) independently of viremia; of these, one developed type-1 diabetes. Cryoglobulinemia was associated with genotype 1 infection and found in 15 subjects (33.3 %): two had low C4 levels and persistent proteinuria. CONCLUSIONS Vertically acquired HCV infection may result in spontaneous clearance in up to 27 % of children. Resolution of infection is higher with genotype 3, usually occurs in preschool age and persists over time. Chronic infection is generally asymptomatic, although hepatomegaly and mild fibrosis may develop. Autoantibodies and cryoglobulins are frequent, whereas the associated clinical manifestations are rare.

Abstract
The estimated prevalence of hepatitis C virus (HCV) infection in India is between 0.5 and 1.5% with hotspots showing much higher prevalence in some areas of northeast India, in some tribal populations and in certain parts of Punjab. Genotype 3 is the most prevalent type of infection. Recent years have seen development of a large number of new molecules that are revolutionizing the treatment of hepatitis C. Some of the new directly acting agents (DAAs) like sofosbuvir have been called game-changers because they offer the prospect of interferon-free regimens for the treatment of HCV infection. These new drugs have not yet been approved in India and their cost and availability is uncertain at present. Till these drugs become available at an affordable cost, the treatment that was standard of care for the whole world before these newer drugs were approved should continue to be recommended. For India, cheaper options, which are as effective as the standard-of-care (SOC) in carefully selected patients, are also explored to bring treatment within reach of poorer patients. It may be prudent to withhold treatment at present for selected patients with genotype 1 or 4 infection and low levels of fibrosis (F1 or F2), and for patients who are non-responders to initial therapy, interferon intolerant, those with decompensated liver disease, and patients in special populations such as stable patients after liver and kidney transplantation, HIV co-infected patients and those with cirrhosis of liver.

Abstract
AIM To review the efficacy and tolerability of pegylated interferon-α and ribavirin for treatment of chronic hepatitis C (CHC) in children in the UK. METHODS Retrospective review of children treated for CHC in 3 UK paediatric specialist liver centres between 2005 and 2010. Data on viral response to treatment, demographic and clinical details were collected. Treatment outcome was assessed by the absence of detectable viral RNA in blood 24 weeks after treatment-sustained viral response (SVR). RESULTS 75 children were included; 34 genotype 1; 39 genotypes 2 and 3; 2 genotype 4. Overall SVR was achieved in 54/71 (76%); 65% genotype 1; 89% genotypes 2 and 3; 100% genotype 4. Early response at 12 weeks was achieved in 53 and sustained in 47 (89%). Data on rapid response after 4 weeks of treatment were available in 25; 17/25 (68%) responded and 16 of these (94%) achieved SVR. IL28 T/T genotype was associated with higher SVR. There were no significant changes in weight and height z scores from baseline compared with 24 weeks post-treatment follow-up. No child discontinued treatment due to side effects, although 43 required dose modification. Treatment affected quality of life (QoL) in the initial 12 weeks of treatment, which improved by the end of treatment. CONCLUSIONS Children respond well to therapy for CHC. Treatment was tolerated with minimal impact on QoL and no significant effect on growth. Knowledge of viral and IL28 genotypes and early viral response is useful to plan treatment in children and provide appropriate counselling.

Abstract
Hepatitis C virus (HCV) is a major health burden infecting 170-210 million people worldwide. Additional 3-4 millions are newly-infected annually. Prevalence of pediatric infection varies from 0.05%-0.36% in the United States and Europe; up to 1.8%-5.8% in some developing countries. The highest prevalence occurs in Egypt, sub-Saharan Africa, Amazon basin and Mongolia. HCV has been present in some populations for several centuries, notably genotypes 1 and 2 in West Africa. Parenteral anti-schistosomal therapy practiced in the 1960s until the early 1980s had spread HCV infection throughout Egypt. Parenteral acquisition of HCV remains a major route for infection among Egyptian children. Insufficient screening of transfusions, unsterilized injection equipment and re-used needles and syringes continue to be major routes of HCV transmission in developing countries, whereas vertical transmission and adolescent high-risk behaviors (e.g., injection drug abuse) are the major routes in developed countries. The risk of vertical transmission from an infected mother to her unborn/newborn infant is approximately 5%. Early stages of HCV infection in children do not lead to marked impairment in the quality of life nor to cognitive, behavioral or emotional dysfunction; however, caregiver stress and family system strain may occur. HCV slowly progresses to serious complications as cirrhosis (1%-2%) and hepatocellular carcinoma (HCC) especially in the presence of risk factors as hemolytic anemias, obesity, treated malignancy, and concomitant human immune deficiency and/or hepatitis B virus co-infection. HCV vaccine remains elusive to date. Understanding the immune mechanisms in patients who successfully cleared the infection is essential for vaccine development. The pediatric standard of care treatment consists of pegylated interferon-α 2a or b plus ribavirin for 24-48 wk. The new oral direct acting antivirals, approved for adults, need further evaluation in children. Sustained virologic response varies depending on the viral load, genotype, duration of infection, degree of aminotransferase elevation, adiposity and single nucleotide polymorphisms of interleukin (IL)-28B locus. The goals of treatment in individual patients are virus eradication, prevention of cirrhosis and HCC, and removing stigmatization; meanwhile the overall goal is decreasing the global burden of HCV. IL-28B polymorphisms have been also associated with spontaneous clearance of vertically acquired HCV infection. The worldwide economic burden of HCV for children, families and countries is estimated to be hundreds of millions of US dollars per year. The United States, alone, is estimated to spend 199-336 million dollars in screening, monitoring and treatment during one decade. The emotional burden of having an HCV infected child in a family is more difficult to estimate.

Abstract
BACKGROUND A systematic review and meta-analysis were conducted to examine the efficacy and safety of pegylated interferon (peg-IFN) alfa-2a and peg-IFN alfa-2b plus ribavirin (RBV) in children and adolescents with chronic hepatitis C virus (HCV). METHODS Medline, Embase, and Cochrane Central Register of Controlled Trials were searched. Clinical trials examining peg-IFN alfa-2a or peg-IFN alfa-2b plus RBV among persons ages 3-18 years with HCV were included. Data were abstracted for complete early virologic response (EVR), sustained virologic response (SVR), relapse, treatment discontinuations, hematologic and dermatologic adverse events, and growth inhibition. RESULTS Eight trials met the inclusion criteria. Results indicate that 70% of subjects (95% confidence interval [CI], 58%-81%) achieved EVR, and 58% (95% CI, 53%-64%) achieved SVR. EVR and SVR were higher for those with HCV genotypes 2/3 than 1/4. Discontinuation due to adverse events and discontinuation due to viral breakthrough were each 4%, discontinuation due to a lack of response was 15%, and relapse was 7%. Anemia, neutropenia, leukopenia, and thrombcytopenia were 11%, 32%, 52%, and 5%, respectively. Alopecia, injection site erythema, and pruritus were 13%, 27%, and 10%, respectively. Small growth inhibitions were observed during treatment. CONCLUSION The results of this meta-analysis indicate that peg-IFN/RBV combination treatment is effective and safe in treating children and adolescents with HCV.

Abstract
HBV and HCV are the predominant causes of chronic viral hepatitis in children and adults. The main purposes of the present review are to provide the reader with a comprehensive overview of the currently available therapies for chronic hepatitis B and C in children and to critically review the current guidelines and indications for treatment provided by the major international societies and by the consensus of expert panels. Overall, a conservative approach is generally warranted in children with chronic hepatitis B. For HCV, the high effectiveness of pegylated interferon and ribavirin in children with genotype 2 or 3 chronic infection supports the decision to treat. For genotype 1 infection the encouraging results of the use of direct antiviral agents in adults suggest a more conservative approach.

Abstract
Hepatitis C virus (HCV) is an RNA virus that affects >180 million individuals worldwide with a high propensity for chronic infection. Children with HCV infection differ from adults in several ways including some modes of transmission, rates of clearance, progression of fibrosis, and the duration of potential chronic infection when acquired at birth. Since the discovery of HCV in 1989, there have been significant advances in the understanding of the virology and natural history of chronic HCV infection in children. In addition, there are now several treatment options for children with chronic hepatitis C infection and many new therapies on the horizon. As a consequence, the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition brought together experts in pediatric hepatology to review the available data in children and provide clinicians with approaches to the diagnosis, management, and prevention of HCV infection in children and adolescents. The guideline details the epidemiology and natural history of HCV infection in children, the diagnostic workup, monitoring and treatment of disease, and provides an update on future treatment options and areas of research.

Abstract
Long-term studies in adults indicate that sustained virologic response (SVR) after combination treatment for chronic hepatitis C (CHC) predicts long-term clearance. Although peginterferon plus ribavirin is now standard care for children with CHC, long-term follow-up studies are not yet available. This study evaluated durability of virologic response over 5 years in children previously treated with interferon alfa-2b plus ribavirin (IFN/R). Ninety-seven of 147 children with CHC, who were treated with IFN/R and completed the 6-month follow-up in two previous clinical trials, participated in this long-term follow-up study. All were assessed annually for up to 5 years; patients with SVR were assessed for durability of virologic response. Children with SVR (n = 56) and those with detectable hepatitis C virus (HCV) RNA 24-week post-treatment (n = 41) were followed for a median of 284 weeks. Overall, 70% (68/97) of patients completed the 5-year follow-up. One patient with genotype 1a CHC had SVR and relapsed at year 1 of follow-up with the same genotype. Kaplan-Meier estimate for sustained response at 5 years was 98% (95% CI: 95%, 100%). Six patients with low-positive HCV RNA levels (n = 4) or missing HCV RNA at the 24-week follow-up visit (n = 2) in the initial treatment studies had virologic response during this long-term follow-up study. Linear growth rate was impaired during treatment with rapid increases in the immediate 6 months post-treatment. Mean height percentile at the end of the 5-year follow-up was slightly less than the mean pretreatment height percentile. Five patients experienced serious adverse events; none related to study drug exposure. SVR after IFN/R predicts long-term clearance of HCV in paediatric patients; growth normalized in the majority of children during the long-term follow-up. Similar long-term results could be expected after peginterferon alfa-2b plus ribavirin treatment.

Abstract
BACKGROUND The outcome of patients with hepatitis C virus (HCV) infection acquired during childhood in the absence of antiviral therapy is not clear. AIMS The purpose of this study was to review the outcome of untreated HCV acquired in childhood. Only population-based studies were included, as referred cases would be predicted to have more severe disease. METHODS A systematic review of the literature was completed up to October 2010 to identify studies where a population was screened for HCV infection that was presumably acquired during childhood. Demographical and clinical data were collected on infected patients who had not been treated with an antiviral. Primary outcome was development of a severe adverse outcome (cirrhosis, hepatoma, need for a liver transplant or liver-related death). RESULTS There were 25 studies reporting a total of 733 infected patients. Liver biopsy results were provided for 180 patients (25%), revealing cirrhosis in eight (1.0% of the total and 4.0% of those who had a biopsy). None of the other patients developed a severe adverse outcome. As a result of the small number of patients with a severe adverse outcome, risk factors for HCV progression could not be identified. CONCLUSION Although HCV can lead to liver transplantation and death during childhood, the vast majority of patients with disease acquired during childhood have slowly progressive disease. There is no clear indication for antiviral therapy in the majority of children with HCV infection.

Abstract
Data on mother-to-child transmitted human immunodeficiency virus/hepatitis C virus (HIV/HCV) coinfection are scarce. A prospective observational study with a cohort of 70 HCV-infected children (13 of whom were HIV/HCV-coinfected; mean follow-up: 7.3 years) is presented. In our series, surrogate markers of disease progression (HCV viremia, maximum alanine aminotransferase values, and spontaneous HCV infection clearance) suggest that the evolution of liver disease in HIV/HCV-coinfected pediatric patients is more aggressive than it is in HCV-only infected children.

Abstract
BACKGROUND AND AIM Treatment of chronic hepatitis C in children is controversial and its role in the clinical practice is unknown. We retrospectively investigated the impact of treatment in a large cohort of children with chronic hepatitis C over the past 20 years. METHODS 376 hepatitis C virus RNA positive children were recruited consecutively in five Italian centres since 1990 and followed for 1-17 years. RESULTS 86 (23%) subjects were treated: 73 with recombinant interferon alone and 13 with pegylated-interferon and ribavirin. Sustained clearance of hepatitis C virus RNA was observed in 25% of the former, in 92% of the latter and in 9% of untreated cases (p < 0.001). Loss of viraemia was recorded in all children with genotype 2-3 and in 6 of 7 with hepatitis C virus genotype 1 treated with combination therapy. At last evaluation 45% of patients were young adults and 15% had cleared viraemia. Overall, 152 (40%) were putative candidates to therapy. CONCLUSIONS Few Italian children with chronic hepatitis C have been treated in the past 20 years. The poor propensity to spontaneous clearance of viraemia and the efficacy of combination therapy should encourage to consider treatment in attempt to shorten the duration of viral replication.

Abstract
Hepatitis C virus (HCV) is the most common cause of chronic liver disease of infectious etiology in children. Most of the children infected with HCV are asymptomatic, and only a few of them develop signs and symptoms of end-stage liver disease early in life. It is not possible to predict either in which patients HCV infection will have a bad outcome or the critical time in early adulthood when disease progression will accelerate. The experiences with therapy in children with chronic hepatitis C are based on earlier and continuing data from adult trials. The currently recommended treatment for chronic HCV infection in adults is the combination of peginterferon-á and ribavirin. The choice of this regimen is based on the results of randomized clinical trials that demonstrated the superiority of this combination treatment over standard interferon-á and ribavirin. Recently, results of pivotal, multicenter, interventional open-label studies on combined treatment with peginterferon-á and ribavirin in children have been published, and the US Food and Drug Administration and the European Medicines Agency have approved the combination therapy in those older than 3 years. The aim of this review is to evaluate critically the available data regarding the safety and efficacy of combination treatment with peginterferon-á and ribavirin in children.

Abstract
BACKGROUND & AIMS This multi-center study aimed to prospectively evaluate the safety and efficacy of a genotype-based Pegylated Interferon alfa-2a/Ribavirin therapy in treatment-naïve hepatitis C virus (HCV), positive HCV serology, and quantifiable HCV RNA, infected children. METHODS Eighteen children with genotypes 2 and 3 patients (group A) were assigned to medication for 24weeks, and 47 children with genotypes 1, 4, 5 and 6 patients (group B) for 48weeks. RESULTS Early response at week 12 was observed in 83% of group A patients and in 57% of group B patients (p<0.05). End of treatment response was achieved in 94% of patients in group A and in 57% in group B (p<0.001). Sustained virologic response was maintained in 89% of patients in group A and in 57% of patients in group B (p<0.01). Ten patients stopped prematurely the treatment, 2 for serious adverse event (acute hepatitis and thyrotoxicosis), and 8 because of no virologic response at week 24. Peginterferon alfa-2a and Ribavirin dose was adjusted in 15 patients (23%), 11 for neutropenia (17%), and 3 patients (5%), for anemia, respectively. Treatment-related adverse events included fever and flu-like symptoms (54%), irritability-depression-change of mood (34%), vomiting (23%), abdominal pain (38%), loss of appetite (21.5%) and dermatitis (29%). No influence on height growth was observed. CONCLUSIONS Pegylated inteferon alfa-2a and Ribavirin treatment allowed to achieve SVR in 57% of pediatric patients with genotypes 1, 4, 5 and 6, and in 94% of genotypes 2 and 3. These results show an improved SVR as compared to reference series in adults with similar regimen.

Abstract
Hepatitis C affects 4-10% of children born to infected mothers, and 80% of them develop chronic infection. Most patients with chronic hepatitis C virus infection are asymptomatic, with persistent or intermittent biochemical abnormalities. Severe liver disease may develop 10 years after onset of infection, with a less than 2% overall risk during the pediatric age. Available therapies have no contraindication in children if otherwise healthy. The US FDA and EMEA have recently approved combined pegylated-IFN-alpha 2b plus ribavirin treatment for children, who should be over 3 years of age in order to avoid severe side effects. Experiences in pilot trials and international studies indicate a response rate of 50% in genotype 1 patients, and more than 90% in genotype 2 or 3 patients, indicating resolution of chronic disease.

Abstract
BACKGROUND The slow progression of hepatitis C virus (HCV) infection could ultimately negatively impact pediatric patients during their lifespan. This study describes the symptomatic and pathophysiologic presentation of HCV infection in a cohort of pediatric outpatients. METHODS HCV-positive patients were identified by diagnosis codes from outpatient visits. Demographic and pathophysiologic indicators (comorbidities, reported symptoms, alanine transaminase, aspartate transaminase, gamma glutamyl transpeptidase, HCV viral load, genotype, and liver biopsy results) were collected and analyzed. RESULTS We reviewed 62 patients with HCV infection who were from 3 months and 19 years of age (M +/- SD, 12.5 +/- 5.8 years). Sixty percent presented with clinical symptoms of fatigue, joint-abdominal pain, bruising/bleeding, or other non-specific symptoms. On liver biopsy (n = 35) 80% had evidence of inflammation, 57% had fibrosis, and 9% had steatosis. All patients with steatosis or cirrhosis reported symptoms. Males were significantly more likely than women to be symptomatic (58.3% vs. 41.7%, P = 0.04). Patients with symptoms were significantly older (M = 13.5 +/- 5.2 vs. 8.9 +/- 5.5 years, P = 0.003). There was a significant inverse relationship between viral load and symptoms (chi = 4.75, P = 0.03). Patients with low viral load (<2 million copies) were 5 times more likely to have symptoms than those with high viral loads (P = 0.03). Significance was also noted between HCV genotype and ALT levels (chi = 3.72, P = 0.05). There were no significant relationships between symptom status and race, comorbidities, alanine transaminase, aspartate transaminase, gamma glutamyl transpeptidase, HCV genotype, or liver histology. CONCLUSION Pediatric patients with HCV can have significant symptoms and physiologic liver changes related to HCV.

Long-term course of chronic hepatitis C in children: from viral clearance to end-stage liver disease. Gastroenterology 2008; 134:1900-7.

Abstract
BACKGROUND & AIMS The natural course of chronic hepatitis C (CHC) in children is not well understood. The aim of this study was to assess the long-term course of CHC in a large sample of otherwise healthy children. METHODS From 1990 to 2005, 504 consecutive antihepatitis C virus (HCV)-positive children were enrolled at 12 centers of a national observatory and were followed up retrospectively/prospectively. RESULTS Putative exposure was perinatal in 283 (56.2%) cases, parenteral in 158 (31.3%), and unknown in 63 (12.5%). At baseline, 477 (94.6%) cases were HCV RNA seropositive, 118 (24.7%) of which were treated with standard interferon alpha. Ten years after putative exposure, the outcome in 359 HCV RNA-positive, untreated patients was (1) undetectable viremia in 27 (7.5%) (by Cox regression analysis, spontaneous viral clearance was independently predicted by genotype 3 [hazard ratio 6.44; 95% confidence interval: 2.7-15.5]) and (2) persistent viremia in 332 (92%) cases. Six of these 332 cases (1.8%) progressed to decompensated cirrhosis (mean age, 9.6 years). This latter group included 5 Italian children perinatally infected with genotype 1a (4 of the mothers were drug users). Thirty-three (27.9%) treated patients achieved a sustained virologic response. CONCLUSIONS Over the course of a decade, few children with chronic HCV infection cleared viremia spontaneously, and those who did were more likely to have genotype 3. Persistent viral replication led to end-stage liver disease in a small subgroup characterized by perinatal exposure, maternal drug use, and infection with HCV genotype 1a. Children with such features should be considered for early treatment.

Abstract
BACKGROUND Interferon (IFN)-alpha2b plus ribavirin is approved for treatment of hepatitis C in children; however, little is known about efficacy and tolerability of pegylated IFN (PEG-IFN)-alpha2b in this population. The objective of this study was to test the efficacy and safety of PEG-IFN-alpha2b plus ribavirin in children with chronic hepatitis C. METHODS Thirty children 3-16 years of age who had detectable hepatitis C virus (HCV) RNA for >or=3 years after exposure and elevated alanine aminotransferase values received PEG-IFN-alpha2b 1.0 microg/kg/wk plus ribavirin 15 mg/kg/d for 24 weeks (genotype 2/3) or 48 weeks (genotype 1/4). The primary endpoint was sustained virologic response (SVR), defined as undetectable HCV RNA (<50 IU/mL) at week 24 of follow-up. RESULTS SVR was achieved in 50% of patients (3/3 genotype 3; 12/27 genotype 1/4). At week 12, 52% of patients were HCV RNA negative and 72% had a >2 log10 decrease in viral load, compared with baseline; 87% and 71% of these patients, respectively, attained an SVR. Therapy was discontinued in 3 patients as a result of adverse events. No patient required ribavirin dose reduction; PEG-IFN-alpha2b dose was reduced in 23% of patients to manage neutropenia. CONCLUSIONS Combination therapy with PEG-IFN-alpha2b and ribavirin treatment was effective in children with chronic hepatitis C. Virologic status at week 12 identified future responders and nonresponders. PEG-IFN-alpha2b and ribavirin were reasonably well tolerated, with no unexpected or permanent adverse effects. Further studies are needed to identify the optimum treatment regimen for this patient population.

Abstract
PURPOSE OF REVIEW Hepatitis C virus infection has recently been recognized as a viral infection with the potential to cause significant complications, including cirrhosis and hepatocellular carcinoma in adults. Changes in our understanding of its natural history in children and recent advances in therapy for acute and chronic hepatitis C are reviewed. RECENT FINDINGS Recent work has demonstrated that, although uncommon, vertical transmission is the most frequent mode of hepatitis C acquisition in children and is enhanced in the setting of maternal co-infection with HIV. Chronic hepatitis C during childhood leads in some cases to development of advanced hepatic fibrosis, with complications including liver failure and liver cancer, which has changed our general approach to this infection. Perhaps the most significant recent advance in this area is our improved understanding of the safety and efficacy of interferon-based antiviral therapies for children with hepatitis C. SUMMARY Hepatitis C virus infection has reached epidemic proportions worldwide; despite its being less prevalent in children than in adults, it poses a significant clinical problem in this age group. Emerging antiviral therapies are currently in clinical trials for adult patients with hepatitis C with encouraging preliminary results, which should be extended to children.
