The Efficacy and Safety of Sofosbuvir and Daclatasvir Treatment in Children and Adolescents With Thalassemia and Hepatitis C Virus Infection. J Clin Exp Hepatol 2024; 14:101310. [PMID: 38264577 PMCID: PMC10801307 DOI: 10.1016/j.jceh.2023.101310] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Accepted: 11/27/2023] [Indexed: 01/25/2024] Open
Abstract
Background/Aim Thalassemia patients are susceptible to hepatitis C virus (HCV) infection due to blood transfusions. Currently, data on treating HCV in thalassemic children with direct-acting antivirals is lacking. This study was performed to determine the efficacy and safety of sofosbuvir-daclatasvir combination therapy in thalassemic children and adolescents. Methods A nonrandomized, open-label, interventional study was carried out in a tertiary care hospital. Consecutive noncirrhotic treatment-naïve thalassemic patients with HCV infection with viremia, within the age group of 6-18 years, were treated with the combination of sofosbuvir-daclatasvir: 200 mg + 30 mg for age 6-11 years (Group A) and 400 mg + 60 mg for age 12-18 years (Group B). The primary endpoint was sustained virological response at 12 weeks (SVR12). Results A total of 70 patients (Group A 45, 64% male; Group B 25, 40% male) were recruited. The mean age was 8.5 years and 13.9 years in the two groups. Mean HCV Ribonucleic acid (RNA) levels in Groups A and B were 446906.1 IU/ml and 256187.8 IU/ml, respectively. SVR12 was achieved in 43 of 45 (95.5%) patients on an intention-to-treat basis and 43 of 44 (97.7%) patients on a perprotocol basis in Group A, and all patients in Group B (100%). In both groups, there was a significant improvement in biochemical parameters. Among the two patients who did not achieve SVR12 in Group A, one required termination of therapy due to urticaria. Conclusion Sofosbuvir-daclatasvir based treatment in noncirrhotic, treatment-naive thalassemic children and adolescents infected with HCV is effective and safe.

ESPGHAN recommendations on treatment of chronic hepatitis C virus infection in adolescents and children including those living in resource-limited settings. J Pediatr Gastroenterol Nutr 2024; 78:957-972. [PMID: 38369891 DOI: 10.1002/jpn3.12160] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Revised: 08/29/2023] [Accepted: 10/25/2023] [Indexed: 02/20/2024]
Abstract
Hepatitis C virus (HCV) infection is a major cause of chronic liver disease worldwide, with more than three million viraemic adolescents and children. Treatment of adults with HCV infection and HCV-related liver disease has advanced considerably thanks to development and improvements in therapy. Direct-acting antiviral regimens are safe and effective. Three regimens with pangenotypic activity (glecaprevir/pibrentasvir, sofosbuvir/velpatasvir and sofosbuvir/velpatasvir/voxilaprevir) and three regimens with genotype-specific activity (sofosbuvir/ribavirin, sofosbuvir/ledipasvir and elbasvir/grazoprevir) have been approved with age-specific limitation for treatment of children with chronic hepatitis C by the European Medicines Agency and the United States Food and Drug Administration. The World Health Organization has set the ambitious target to eliminate hepatitis C as a major public health threat by 2030 and based its actions against HCV on the large use of direct acting antivirals. These updated European Society for Pediatric Gastroenterology, Hepatology and Nutrition recommendations on treatment of hepatitis C describe the optimal therapeutic management of adolescents and children with HCV infection including specific indications for those living in resource-limited settings.

Liver Int 2024; 44:663-681. [PMID: 38293756 DOI: 10.1111/liv.15827] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Revised: 10/13/2023] [Accepted: 12/18/2023] [Indexed: 02/01/2024]
Abstract
BACKGROUND AND AIMS We evaluated the effectiveness and safety of pan-genotypic regimens, glecaprevir/pibrentasvir (GLE/PIB), sofosbuvir/velpatasvir (SOF/VEL), and sofosbuvir/daclatasvir (SOF/DCV) and other direct-acting antivirals (DAA) regimens for the treatment of hepatitis C virus (HCV)-infected adolescents (12-18 years), older children (6-11 years), and young children (3-5 years). The purpose of this systematic review and meta-analysis was to inform the World Health Organization (WHO) guidelines. METHODS We included clinical trials and observational studies published up to August 11, 2021, that evaluated DAA regimens in HCV-infected adolescents, older children, and young children. We searched MEDLINE, EMBASE, and CENTRAL databases and key conference abstracts. Sustained virological response 12 weeks after the end of treatment (SVR12), adverse events (AEs), and treatment discontinuation were the outcomes evaluated. Risk of bias was assessed using a modified version of the ROBINS-I tool. Data were pooled using random-effects models, and certainty of the evidence was assessed using the GRADE approach. RESULTS A total of 49 studies including 1882 adolescents, 436 older children, and 166 young children were considered. The SVR12 was 100% (95% Confidence Interval: 96-100), 96% (90-100), and 96% (83-100) for GLE/PIB in adolescents, older, and young children, respectively; 95% (90-99), 93% (86-98), and 83% (70-93), for SOF/VEL, respectively; and 100% (97-100) and 100% (94-100) for SOF/DCV in adolescent and older children, respectively. There was a clear trend towards a higher rate of any reported AE from adolescents (50%), older children (53%), to young children (72%). Serious AEs and treatment discontinuations were uncommon in adolescents and older children (<1%) but slightly higher in young children (3%). CONCLUSIONS All three pan-genotypic DAA regimens were highly effective and well-tolerated and are now recommended by the WHO for use in adults, adolescents, and children down to 3 years, which will simplify procurement and supply chain management. The evidence was based largely on single-arm non-randomized controlled studies. Moreover, there were also missing data regarding key variables such as route of HCV acquisition, presence or absence of cirrhosis, or HIV co-infection that precluded evaluation of the impact of these factors on outcomes.

Abstract
Children represent only a small proportion of those infected with the hepatitis C virus (HCV) compared to adults. Nevertheless, a substantial number of children have chronic HCV infection and are at risk of complications including cirrhosis, portal hypertension, hepatic decompensation with hepatic encephalopathy, and hepatocellular carcinoma in adulthood. The overall prevalence of the HCV in children was estimated to be 0.87% worldwide. The HCV spreads through the blood. Children born to women with chronic hepatitis C should be evaluated and tested for HCV due to the known risk of infection. The course of treatment for hepatitis C depends on the type of HCV. Currently, there are two pan-genotype HCV treatments (Glecaprevir/pibrentasvir and Sofosbuvir/velpatasvir) for children. We aim to review the updated clinical guidelines on the management of HCV infection in children, including screening, diagnosis, and long-term monitoring, as well as currently published clinical trials and ongoing research on direct acting antiviral hepatitis C treatment in children.

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

Abstract
Viral infections are particularly common among children. They often have a mild course, are self-limiting and do not need any specific treatment. However, in some cases, the disease can be severe and lead to permanent disabilities. A variety of antiviral drugs are available for the treatments of certain infectious agents: for instance, acyclovir is used to treat herpes simplex virus encephalitis. Recommendations for flu treatment may change according to the current epidemiological surveillance data, on the basis of which antiviral sensibility can be forecast: recommended drugs for the 2020-21 flu season are oseltamivir, zanamivir, peramivir and baloxavir. Some drugs are used to treat congenital infections, such as valganciclovir and ganciclovir in congenital cytomegalovirus infection. Antiretroviral prophylaxis in newborns from HIV-1 infected mothers must be initiated as soon as possible, with one or more drugs according to therapeutic regimens based on the baby's risk category. According to the most recent guidelines, antiretroviral therapy must be started at diagnosis. Several antiretroviral drugs are available today and approved for use in children, so several combinations can be made. However, out of the 29 antiretroviral drugs approved for adults, only 38% (11/29) are approved for children under the age of two and about 60% (18/29) for children under the age of twelve. Treatment with direct antiviral agents against hepatitis C virus is approved for children over the age of three; it consists in different therapeutic regimens chosen on the basis of the viral genotype (ledipasvir/sofosbuvir for genotypes 1, 4, 5 and 6, sofosbuvir/ribavirin for genotypes 2 and 3, sofosbuvir/velpatasvir and glecaprevir/pibrentasvir for all genotypes) and it has dramatically changed the course of the illness. Many molecules have been studied in order to treat SARS-CoV-2 infection, but only remdesivir seems to play a role in shortening recovery time, although inclusion criteria are very specific and data on the use in children is limited.

Abstract
Direct-acting antiviral (DAA) treatment for 8 weeks has a sustained virological response rate in adults with chronic hepatitis C. We have conducted a systematic review and meta-analysis to compare the efficacy and safety of the 8-week vs. 12/24-week DAA treatment in adolescents and children with CHC. The PubMed, Web of Science, and Cochrane databases were searched for the relevant articles from January 1, 2017 to August 28, 2020 and further screened for literature reviews on April 1, 2021. Pool proportions with 95% CIs for SVR12 were summarized with fixed/random effects models using Freeman–Tukey double arcsine transformation. Subgroup analysis was used to explore the source of heterogeneity. Thirty-six relevant publications were identified. For adolescents aged 12–17 years old, the pooled SVR12 and AE rate were 99.4% (95% CI: 98.7–99.9) and 34.7% (95% CI: 31.9–37.6). No one discontinued treatment due to drug intolerance. In addition, the SVR12 adolescents treated for 12 and 8/24 weeks were 99.3% (95% CI: 98.4–99.9) and 100%, respectively. The pooled SVR12 rate, AEs, and SAEs for children younger than 12 years were 98.9% (95% CI: 97.3–99.8), 51.6% (95% CI: 47.0–56.2), and 1.1% (95% CI: 0.4–2.5), respectively. The most common AE was fatigue (28.4%). The SVR12 was 98.8% (95% CI: 97.1–99.8) and 100% for the pediatric patients treated for 12 weeks and 8/24 weeks, respectively. Taken together, DAAs are generally effective against CHC and well-tolerated by the adolescents and children. A treatment duration of 8 weeks is equally effective and safe as 12/24 weeks in this demographic group.

Abstract
The prevalence and burden of hepatitis C virus (HCV) in children are poorly understood mainly as a result of the fact that studies in this population have largely been done in high-risk groups and in highly endemic regions. Epidemiological studies estimate the viraemic prevalence in the paediatric population aged 0-18 years at 0.13%, corresponding to 3.26 million children with HCV in 2018. While vertical transmission occurs in up to 5% of neonates born to infected mothers, with preference for those with high viral load and co-infection with the human immunodeficiency virus, injection drug use is the prevalent modality of HCV infection among adolescents. Notwithstanding the fact that HCV usually has an indolent course in children and adolescents, hepatitis C may progress to significant liver disease in a fraction of patients. The finding of severe disease or cirrhosis in a minority of paediatric patients with HCV underscores the importance of early diagnosis and treatment in order to prevent long-term morbidity. Universal screening of HCV in pregnant women is key to identify infants exposed to such a risk and link them to care. Recently, direct-acting antiviral drugs proved to be as safe and effective in young HCV patients as in adults, and these agents are now approved for treatment of paediatric patients as young as 3 years. This review provides a contemporary overview of the HCV disease burden in children, with a particular focus on its treatment in the era of direct-acting antiviral agents.

ZusammenfassungZur Behandlung der chronischen Hepatitis C wurden in den letzten Jahren direkt wirkende antivirale Medikamente (DAA) zugelassen und sind bei Erwachsenen etabliert. Sie machten die interferonbasierten Therapien obsolet. Auch für Kinder und Jugendliche stehen seit Kurzem einige DAA zur Verfügung, die überwiegend ab dem Alter von 3 Jahren eingesetzt werden können.Die chronische Hepatitis C wird bei Kindern überwiegend vertikal übertragen und ist selten. Sie ist zwar zunächst eine wenig aktive und progrediente Erkrankung, kann aber im Erwachsenenalter in eine Leberzirrhose mit der Folge eines hepatozellulären Karzinoms übergehen. Die Diagnose ist mit der Bestimmung des Anti-HCV (IgM/IgG) und der HCV-RNA im Serum mit Genotypisierung leicht zu stellen. Die DAA werden oral appliziert und ausgesprochen gut toleriert. Drei Wirkstoffkombinationen stehen aktuell zur Verfügung, und 2021 wird eine weitere zugelassen. Die Heilungschancen sind mit über 95 % ausgesprochen gut und anhaltend.Im eigenen Krankengut wurden 25 Jungen und Mädchen überwiegend mit Genotyp 1 im Alter von 4 bis 17 Jahren mit DAA behandelt. Unabhängig von der Höhe der HCV-RNA im Serum waren alle bereits nach 4 Wochen HCV-RNA negativ und erzielten einen dauerhaften Erfolg.Die wesentliche Aufgabe ist nun, alle Kinder und Jugendlichen mit einer chronischen Hepatitis C zu identifizieren. Bei der äußerst guten Heilungschance kann davon ausgegangen werden, dass das Eradikationsziel in dieser Altersgruppe in absehbarer Zeit erreicht werden kann.

Abstract
Chronic infections by hepatitis B virus (HBV) and hepatitis C virus (HCV) major causes of advanced liver disease and mortality worldwide. Although regarded as benign infections in children, their persistence through adulthood is undoubtedly of concern. Recent advances in HCV treatment have restored the visibility of these conditions and raised expectations for HBV treatment, which is currently far from being curative. Herein we describe direct-acting antivirals available for pediatric HCV (sofosbuvir/ledipasvir, sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) and their real-world use. A critical review of the HBV pediatric classification is provided. Anti-HBV investigational compounds are reviewed in light of the pathophysiology in the pediatric population, including capsid assembly modulators, antigen secretion inhibitors, silencing RNAs, and immune modifiers. Recommendations for screening and management of immunosuppressed children or those with other risk factors or comorbidities are also summarized.

Abstract
Chronic hepatitis C virus (HCV) infection presents a significant global public health burden. In 2015, over 400000 deaths worldwide were attributed to HCV infection. This led the World Health Organization (WHO) in 2016 to set the ambitious goal of eliminating HCV by 2030. Adult-centered guidelines have been established in order to provide direction for healthcare professionals, allowing integration of the newest screening policies and therapeutic strategies into their practices. However, for children and adolescents, HCV is a significant, unrecognized public health problem. HCV infection rates in the United States in women of childbearing age and those who are pregnant have increased in parallel with the rising opioid epidemic. An estimated 29000 women with HCV infection gave birth each year from 2011 to 2014 in the United States, with approximately 1700 of their infants being infected with HCV. Newer HCV-specific therapeutics, namely direct acting antivirals (DAA), has brought a new and highly successful approach to treatment of hepatitis C. Recent studies have confirmed similar levels of effectiveness and safety of DAA therapies in the pediatric population. Thus, an enhanced cascade of care, which should include the population under 18 years of age, can help achieve the WHO goal by focusing on elimination in the youngest populations. This review will present an overview of the natural history, clinical features, and management of HCV in children and adolescents.

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

Abstract
BACKGROUND The aim of this prospective study was to analyze liver fibrosis in teenagers with chronic hepatitis C (CHC) using noninvasive methods. METHODS Thirty-five patients with CHC, 12-17 years of age (mean 14.2 ± 1.8 years; 22/35, 63% male) were included. Most of them (29/35, 83%) were infected vertically, 21/35 (60%) were treatment-naive, 30/35 (86%) were infected with genotype 1 and 5/35 (14%) were infected with genotype 4 HCV. In all patients, evaluation of liver fibrosis was performed using transient elastography (TE) and measurement of the following serum biomarkers: aspartate transaminase-to-platelet ratio index (APRI) and Fibrosis-4 index (FIB-4). Using liver stiffness measurement (LSM) results as a reference, the diagnostic performance of APRI and FIB-4 was assessed by calculating area under the receiver operating characteristics curve. RESULTS Transient elastography results revealed no or mild fibrosis (F0/1 in METAVIR scale) in 31/35 (89%) patients. In 4/35 (11%) patients, significant fibrosis was observed (F ≥ 2), including 3/35 (9%) with cirrhosis (F4). The median APRI was 0.32, and the median FIB-4 was 0.32. LSM was associated with both APRI and FIB-4 [r = 0.61, 95% confidence interval (CI) 0.35-0.79, P = 0.0001; and r = 0.60, 95% CI 0.32-0.78, P = 0.0002, respectively]. For the diagnosis of significant fibrosis, the area under the receiver operating characteristics (95% CI) for both APRI and FIB-4 was 0.855 (0.695-0.951). APRI, with a cutoff >0.374, predicted significant fibrosis, with 100% sensitivity and 67.7% specificity, whereas FIB-4, with a cutoff >0.402, predicted significant fibrosis, with 75.0% sensitivity and 90.3% specificity. CONCLUSIONS Significant fibrosis, including cirrhosis, may occur in teenagers with CHC. Serum biomarkers (APRI, FIB-4) correlate positively with LSM.

Abstract
BACKGROUND The effect of direct-acting anti-virals (DAAs) in children and adolescents with chronic hepatitis C virus (HCV) infection is difficult to determine, since few, aged between 3 and 18 years, have been enrolled in clinical trials, and some data come from observational studies. AIM To summarise the evidence on efficacy and safety of DAAs in children and adolescents with chronic HCV infection. METHODS We performed a systematic review and meta-analysis of prospective studies on the efficacy and safety of DAAs in subjects <18 years of age. We considered the sustained virological response at post-treatment week 12 as efficacy outcome and adverse events as safety outcome. We considered intervention effect for each study arm by calculating the proportion of sustained virologic response at post-treatment week 12 in subjects receiving all doses of treatment and proportion of adverse events in subjects receiving at least one dose of treatment. Pooled proportions were calculated using the Freeman-Tukey double arcsine transformation. Random effects model was used for all analyses. RESULTS Among 39 included studies (1796 subjects), the pooled proportion among those receiving all doses of treatment and reaching sustained virologic response at post-treatment week 12 was 100% (95% confidence interval: 100-100). Considering subjects receiving at least one dose of treatment, lowest estimates were reported among children with cirrhosis (83%). Headache and fatigue were the most common adverse events. Serious adverse events were uncommon. CONCLUSIONS Children and adolescents with chronic HCV infection can be safely treated with DAAs with similar efficacy as reported in adults.

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
In recent years, significant progress in the antiviral treatment of chronic hepatitis C (CHC) has been made due to the development of interferon-free therapies. Three different highly effective, oral direct-acting antiviral (DAA) regimens have been approved for use in adolescents with CHC between the ages of 12-years-old and 17-years-old in Europe. According to the current recommendations, all treatment-naïve and treatment-experienced children with CHC virus infection should be considered for DAA therapy to prevent the possible progression of hepatitis C virus-related liver disease and its complications. However, the novel coronavirus disease 2019 outbreak, which was classified as a pandemic in March 2020, is currently spreading throughout the world, resulting in a disruption of the healthcare system. This disruption is having a negative impact on the care of patients with chronic diseases, including children with CHC. Thus, several efforts have to be made by pediatric hepatologists to prioritize patient care in children with CHC. These efforts include promoting telemedicine in the outpatient setting, using local laboratory testing for follow-up visits, and engaging in the home delivery of DAAs for patients under antiviral therapy whenever possible.

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
Over 3 million paediatric patients globally and ~50 000 in the United States are estimated to be infected with HCV. Eradicating HCV in children helps prevent liver fibrosis, cirrhosis and hepatocellular carcinoma; reduces extra-hepatic manifestations of HCV; improves quality of life; and increases survival. The 2019 American Association for the Study of Liver Diseases-Infectious Diseases Society of America (AASLD-IDSA) guidelines now recommend direct-acting antiviral (DAA) treatment with an approved regimen for all children and adolescents with HCV infection aged ≥3 years. We conducted a descriptive review of the new DAA treatments for HCV infection in the paediatric population. Ledipasvir/sofosbuvir (LDV/SOF) and sofosbuvir with ribavirin (SOF/RBV) are now approved for those ≥3 years old under specific clinical scenarios; sofosbuvir/velpatasvir (SOF/VEL) is the only pangenotypic agent approved for those ≥6 years or ≥17 kg, and glecaprevir/pibrentasvir (GLE/PIB) is approved for adolescents ≥12 years old or ≥45 kg. These DAA regimens are well-tolerated and have comparable sustained virologic response rates at 12 weeks post-treatment compared to those reported in adults (close to 100%). The introduction of DAAs has significantly changed the landscape of HCV treatment in adults and children with HCV infection and has increased confidence that the 2030 World Health Organization elimination goal may be attainable. Further studies are warranted to determine the optimal treatment for children with HCV infection, including timing, regimen and duration. Additionally, with the recent paediatric approvals, long-term safety data are needed.

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
OBJECTIVE This position paper written by the Hepatitis Expert Team of the Federation of International Societies of Pediatric Gastroenterology, Hepatology, and Nutrition aimed to systematically evaluate clinical practice guidelines (CPGs), medical consensus, and position papers on the use of direct-acting antivirals (DAA) to treat chronic hepatitis C virus (HCV) infection in adolescents and children in order to compare recommendations and provide the basis for developing a unified position statement. METHODS MEDLINE, Cochrane-Library, National Guideline Clearinghouse and select websites of relevant societies/organizations were used to identify CPGs, medical consensus and position papers between 2011-2019. RESULTS A total of 5 documents were analysed: 3 CPGs, 1 medical consensus, and 1 position paper. All publications were consistent in recommending DAA treatment for adolescents (12-17 years old) with chronic HCV infection. Similarly, all of these publications consistently recommended deferring therapy for children between 3 and 11 years of age until DAA became available as standard of care. Finally, none of the included publications recommended treating children younger than 3 years old. By contrast, there was significant discrepancy across the retrieved documents regarding specific DAA regimens and treatment strategies. CONCLUSIONS There is strong consensus on treating all adolescents with chronic HCV infection with DAA and on delaying therapy in younger children until these agents are approved for them. Interferon-based therapies should be avoided. Specific recommendations regarding which DAA regimen to use and treatment duration varied significantly. Key stakeholders need to convene to standardize therapeutic strategies at a global level if we are to eradicate HCV in children.

Abstract
Although direct-acting antivirals (DAAs) have significantly increased the sustained virological response (SVR) rates in chronic hepatitis C virus (HCV)-infected adult patients, the efficacy and safety for children remain unclear. We herein report three HCV-infected children who received DAA treatment. The patients were girls 10-13 years old who had been infected with genotype 1b HCV by vertical transmission based on a phylogenetic tree analysis. Two patients were treated with 12 weeks of ombitasvir/paritaprevir/ritonavir, and the other patient was treated with 8 weeks of glecaprevir/pibrentasvir. All children received DAA doses that were similar to the dosages for adult patients. None developed adverse events, and all children achieved an SVR.

Abstract
IMPORTANCE A 2013 review for the US Preventive Services Task Force (USPSTF) of hepatitis C virus (HCV) screening found interferon-based antiviral therapy associated with increased likelihood of sustained virologic response (SVR) and an association between achieving an SVR and improved clinical outcomes. New direct-acting antiviral (DAA) regimens are available. OBJECTIVE To update the 2013 review on HCV screening to inform the USPSTF. DATA SOURCES Ovid MEDLINE, the Cochrane Central Register of Controlled Trials, and the Cochrane Database of Systematic Reviews through February 2019, with surveillance through September 2019. STUDY SELECTION Randomized clinical trials (RCTs) and nonrandomized treatment studies of HCV screening and DAA therapy; cohort studies on screening, antiviral therapy, and the association between an SVR after antiviral therapy and clinical outcomes. DATA EXTRACTION AND SYNTHESIS One investigator abstracted data; a second checked accuracy. Two investigators independently rated study quality. MAIN OUTCOMES AND MEASURES Mortality, morbidity, quality of life, screening and treatment harms, and screening diagnostic yield. RESULTS Eight RCTs of DAA therapy vs placebo or an outdated antiviral regimen, 48 other treatment studies, and 33 cohort studies, with a total of 179 230 participants, were included. No study evaluated effects of HCV screening vs no screening. One new study since the 2013 review (n = 5917) found similar diagnostic yield of risk-based screening (sensitivity, 82%; number needed to screen to identify 1 HCV case, 15) and birth cohort screening (sensitivity, 76%; number needed to screen, 29), assuming perfect implementation. Ten open-label studies (n = 3292) reported small improvements in some quality-of-life and functional outcomes (eg, less than 3 points on the 0 to 100 36-Item Short Form Health Survey physical and mental component summary scales) after DAA treatment compared with before treatment. Two cohort studies (n = 24 686) found inconsistent associations of antiviral therapy vs no therapy with risk of hepatocellular carcinoma. Forty-nine treatment studies (n = 10 181) found DAA regimens associated with pooled SVR rates greater than 95% across genotypes, and low short-term rates of serious adverse events (1.9%) and withdrawal due to adverse events (0.4%). An SVR after antiviral therapy was associated with decreased adjusted risk of all-cause mortality (13 studies, n = 36 986; pooled hazard ratio [HR], 0.40 [95% CI, 0.28-0.56) and hepatocellular carcinoma (20 studies, n = 84 491; pooled HR, 0.29 [95% CI, 0.23 to 0.38]) vs no SVR. CONCLUSIONS AND RELEVANCE Direct evidence on the effects of HCV screening on clinical outcomes remains unavailable, but DAA regimens were associated with SVR rates greater than 5% and few short-term harms relative to older antiviral therapies. An SVR after antiviral therapy was associated with improved clinical outcomes compared with no SVR.

Abstract
The pangenotypic regimen of glecaprevir and pibrentasvir (G/P) is approved to treat adults with chronic hepatitis C virus (HCV) infection and has yielded high cure rates in adults in clinical trials. Approved treatment options for pediatrics may include ribavirin. A pangenotypic regimen for pediatric patients remains an unmet need. DORA is an ongoing phase 2/3, nonrandomized, open-label study evaluating the pharmacokinetics (PK), safety, and efficacy of G/P in pediatric patients with chronic HCV. This analysis includes Part 1 of the study, conducted in adolescent patients 12-17 years of age given the adult regimen of G/P (300 mg/120 mg) once daily for 8-16 weeks according to the indication durations used in adults. Patients were either treatment naïve or experienced with interferon-based regimens. The primary PK endpoint was steady-state exposures for glecaprevir and pibrentasvir; the primary efficacy endpoint was sustained virologic response 12 weeks after treatment (SVR12). The secondary efficacy endpoints were on-treatment virologic failure, relapse, and reinfection. Safety and tolerability were monitored. Part 1 enrolled 48 adolescent patients infected with genotypes 1, 2, 3, or 4, of whom 47 were administered G/P. All 47 patients (100%) achieved SVR12. No on-treatment virologic failures or relapses occurred. PK exposures of glecaprevir and pibrentasvir were comparable to exposures in adults. No adverse events (AEs) led to treatment discontinuation, and no serious AEs occurred. Conclusion: Adolescent patients with chronic HCV infection treated with G/P achieved a comparable exposure to adults, 100% SVR12 rate, and safety profile consistent with that in adults. This pangenotypic regimen demonstrated 100% efficacy within the adolescent population in as little as 8 weeks of treatment.

Abstract
Currently, the only approved hepatitis C virus (HCV) treatment for children aged <12 years is pegylated interferon plus ribavirin. In an open-label study, we evaluated the safety and efficacy of sofosbuvir plus ribavirin for 12 weeks in children aged 3 to <12 years chronically infected with genotype 2 or for 24 weeks in patients with genotype 3. Patients aged 3 to <6 years weighing <17 kg received sofosbuvir 150 mg, and patients aged 3 to <6 years weighing ≥17 kg and all patients aged 6 to <12 years received sofosbuvir 200 mg once daily. Intensive pharmacokinetic sampling conducted in each age group confirmed the appropriateness of sofosbuvir doses. For all patients, ribavirin dosing was determined by baseline weight (up to 1,400 mg/day, two divided doses). The primary efficacy endpoint was sustained virologic response 12 weeks after therapy (SVR12). Fifty-four patients were enrolled (41 aged 6 to <12 years and 13 aged 3 to <6 years). Most were treatment naïve (98%) and infected perinatally (94%). All but one patient achieved SVR12 (53/54, 98%; 95% confidence interval, 90%-100%). The patient who did not achieve SVR12 was a 4-year-old who discontinued treatment after 3 days because of "abnormal drug taste." The most commonly reported adverse events in patients aged 6 to <12 years were vomiting (32%) and headache (29%), and those in patients aged 3 to <6 years were vomiting (46%) and diarrhea (39%). One 3-year-old patient had a serious adverse event of accidental ribavirin overdose requiring hospitalization for monitoring; this patient completed treatment and achieved SVR12. Conclusion: Sofosbuvir plus ribavirin was well tolerated and highly effective in children aged 3 to <12 years with chronic HCV genotype 2 or 3 infection.

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
Chronic hepatitis C certainly is a global health burden in children as well as in adults. Spontaneous viral clearance can occur in early childhood but is uncommon thereafter. Although the majority of cases are asymptomatic during childhood and young adulthood, without an effective treatment, children who acquire HCV via vertical transmission can develop chronic liver disease and other complications including end-stage liver disease and hepatocellular carcinoma in adulthood. Efforts from worldwide health organizations, the pharmaceutical industry, and clinical and research institutions have resulted in very effective interferon-free therapy with direct-acting antiviral agents (DAAs) for HCV-infected children. In this manuscript, we will briefly review the epidemiology of HCV in children, historic treatment, current published data on DAAs in children and conclude with suggestions for management of the child with HCV in the era of DAAs.

Abstract
BACKGROUND Childhood cancer survivors are potentially at a higher risk of infection with hepatitis C virus (HCV). The effects of all-oral direct-acting antiviral therapy (DAA) on both the HCV infection as well as the state of cancer remission have not been well investigated in this population.
AIM To test the effects of dual sofosbuvir/daclatasvir (SOF/DCV) therapy in the treatment of chronic HCV in survivors of hematologic malignancy in pediatric age group.
METHODS We conducted a prospective, uncontrolled, open-label multicenter study. A total of 20 eligible, chronic HCV, genotype-4, infected children who had been in continuous complete remission from hematologic cancer (leukemia/lymphoma) for at least one year were included in the study. All patients were treated with combined SOF/DCV for 12 wk. Patients were monitored throughout the study till 12 wk after end of treatment for safety and efficacy outcomes including the sustained virologic response 12 (SVR12) rate, hematological indices, liver and kidney functions.
RESULTS The intent-to-treat SVR12 rate was 20 of 20 (100%; 95%CI: 84%-100%). All patients showed normalized liver enzymes from week-4. All hematological indices, liver and kidney functions were kept normal throughout the study. No fatalities or treatment-emergent serious or severe adverse events were reported throughout the study.
CONCLUSION SOF/DCV combined therapy could be used safely and effectively in the treatment of chronic HCV genotype-4 infection in leukemia/lymphoma treated children. No relapses were detected during treatment and throughout the follow up period for either the original malignant disease or the HCV infection.

Effectiveness of 8-week sofosbuvir/ledipasvir in the adolescent chronic hepatitis C-infected patients. Eur J Gastroenterol Hepatol 2019; 31:1004-1009. [PMID: 30676473 DOI: 10.1097/meg.0000000000001360] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/18/2022]
Abstract
BACKGROUND The sustained virological response (SVR) rate for the 12-week sofosbuvir (SOF)/ledipasvir (LVD) treatment of adolescent genotype-4 patients is high. The aim of this study is to evaluate 8 versus 12-week treatment efficacy and safety in adolescent genotype-4 patients. PATIENTS AND METHODS In total, 157 chronic hepatitis C-infected adolescent patients (mean age 14±2 years, 62% males) were included in this study. All patients received a morning dose of SOF (400 mg)/LVD (90 mg) as a single tablet for 8 and 12 weeks. Laboratory and biochemical monitoring were performed at weeks 4 and 8, end of treatment (8/12) and 12 weeks after the end of treatment (SVR12). RESULTS In total, SVR12 was 98% [95% confidence interval (CI): 96-100] for all treated patients. For patients treated for 12 weeks, SVR12 was 97.6% (95% CI: 96-101) (82/84 patients), and 98.6% (95% CI: 93-101) (72/73) patients for those treated for 8 weeks. For both regimens, no serious adverse effects, treatment discontinuation or cases of death were detected. The main adverse effects for the 8-week patient group were fatigue (2.8%), headache (1.4%), nausea (1.4%) and epigastric tenderness (1.4%). For the 12-week-treated group, adverse events were epigastric tenderness (1.2%), nausea (1.2%), diarrhoea (2.4%) and rash (2.4%). Three patients were lost to follow-up: two were in the 12-week treatment group and one was in the 8-week group. All of them reached end of treatment but were lost before SVR12. No relapsers were observed in either group. CONCLUSION Eight weeks of treatment of SOF/LVD combination is equally effective and safe as 12 weeks in adolescent genotype-4 patients.

Abstract
The burden of paediatric Hepatitis C virus (HCV) infection across Europe is unknown, as are current policies regarding monitoring and treatment. This collaborative study aimed to collect aggregate data to characterise the population of ≤18-year-olds with HCV infection in specialist follow up in a 12-month period (2016) across the PENTAHep European consortium, and investigate current policies around monitoring and treatment. A cross-sectional, web-based survey was distributed in April 2017 to 50 paediatricians in 19 European countries, covering patients' profile, and monitoring and treatment practices. Responses were received from 38/50 clinicians collectively caring for 663 children with chronic HCV infection of whom three-quarters were aged ≥6 years and 90% vertically infected. HCV genotype 1 was the most common (n 380; 57.3%), followed by genotype 3, 4 and 2. Seventeen children (3%) with chronic HCV infection were diagnosed with cirrhosis, and six were reported to have received liver transplantation for HCV-related liver disease. The majority (n 425; 64.1%) of the European children with HCV infection remained treatment-naive in 2016. Age affected clinicians' attitudes towards treatment; 94% reported being willing to use direct-acting antivirals, if available, in adolescents (aged ≥11 years), 78% in children aged 6-10 and 42% in those 3-5 years of age (Pearson correlation coefficient -0.98; P 0.0001). This survey provides the largest characterisation of the population of children in clinical follow-up for chronic HCV infection in Europe, alongside important contextual information on their management and treatment. Discussion is needed around strategies and criteria for use of direct-acting antivirals in these children.

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
Chronic hepatitis C virus (HCV) infection carries increased risks for morbidity and mortality in patients undergoing allogeneic haematopoietic stem cell transplantation (HSCT) but has become curable through the advent of directly acting antiviral compounds. Current guidelines of the American Society for Blood and Marrow Transplantation (ASBMT) recommend that HCV-infected HSCT candidates preferably start and complete therapy prior to transplant. However, this is often not feasible due to time constraints or treatment-limiting comorbidities, conditions and treatments. For these reasons, data on the safety of antiviral treatment, its efficacy to achieve durable eradication of the virus until full immune recovery, and late effects of former HCV infection in patients receiving HSCT are unknown. Here, we report the course of two paediatric patients with chronic HCV infection who received a full course of directly acting antivirals prior to allogeneic HSCT and achieved and maintained viral eradication throughout transplantation until complete immune recovery.

Cost Effectiveness of Early Treatment with Direct-Acting Antiviral Therapy in Adolescent Patients with Hepatitis C Virus Infection. J Pediatr 2019; 207:90-96.

Abstract
OBJECTIVE To evaluate the cost effectiveness of early treatment with direct-acting antiviral therapy in adolescent patients with chronic hepatitis C virus (HCV) infection compared with treatment deferral. STUDY DESIGN We constructed a Markov model to assess the cost effectiveness of treating a hypothetical cohort of 30 000 adolescent patients with chronic HCV at age 12 years compared with deferring treatment until adulthood from a societal perspective. Model inputs for transition probabilities, HCV treatment and medical care costs, and quality-adjusted life-year (QALY) utilities were derived from the literature and wholesale acquisition estimates. Deterministic sensitivity analyses varied parameters for non-HCV medical care and treatment cost, reinfection rates, treatment uptake, disease progression, liver transplant survival, and treatment with recently approved pangenotypic direct-acting antiviral agents. Discounted costs and total QALYs per person were quantified after 30 years. Cost effectiveness was evaluated as the incremental change in total medical costs per QALY gained. RESULTS The incremental cost effectiveness of early treatment initiation compared with deferred treatment was approximately $27 000 per QALY gained after 30 years and considered cost effective. In a scenario analysis, hypothetical treatment initiation with currently available pangenotypic agents would be even more cost effective, ranging from $10 000 to $21 000 per QALY gained. Cost-effectiveness estimates were sensitive to variations in decompensated cirrhosis progression in adolescence, adult reinfection, and treatment uptake in adults. CONCLUSIONS Early treatment in adolescent patients with chronic HCV infection with currently available direct-acting antivirals seems to be cost effective compared with deferred treatment. Future efforts to control the HCV epidemic should include increasing the number of children treated.

Abstract
Direct-acting antivirals have become available for treating chronic HCV (hepatitis C virus) infection in adults and, recently, in children at least 12 years old. Our aim was to investigate the safety and efficacy of combined sofosbuvir (SOF)/daclatasvir (DCV) for HCV Genotype 4 in children aged 8 to 18 years or weighing 17 kg or more. A total of 40 chronic HCV-infected, treatment-naïve children with well compensated livers were recruited from two sites. Patients received combined therapy of SOF (400 mg/d for patients weighing greater than 45 kg; 200 mg/d for patients weighing 17 to 45 kg) and DCV (60 mg/d for patients weighing greater than 45 kg; 30 mg/d for patients weighing 17 to 45 kg) for 12 weeks. They were followed up regularly by clinical examination and laboratory tests during treatment (weekly in the first month then monthly to the end of treatment), every 3 months for 6 months post-treatment, and at 48 weeks post-treatment. In our cohort, which included 45% of children below the age of 12 years (72.5% genotype 4 and 27.5% mixed genotype 4 and 1), end of treatment response (ETR) was 97.5%. Sustained virologic response for weeks 12 and 24 post-treatment (SVR12 and SVR24) were 97.5% and 95%, respectively, on an intention to treat basis, and 100% and 100% for those who completed the study protocol. Observed side effects were mild and none required drug cessation. Combined SOF/DCV was found to be effective and safe for treating HCV Genotype 4-infected children, 8 years of age and above.

Abstract
OBJECTIVES To assess the efficacy and safety of sofosbuvir based generic Direct Acting Antivirals (DAAs) in treatment of Hepatitis C virus (HCV) in adolescents with thalassemia major (TM). METHODS In this prospective single-arm study, 18 TM adolescents with Chronic Hepatitis C received sofosbuvir based generic DAAs. Patients with genotype 1 and genotype 3 received ledipasvir and daclatasvir respectively. Two cirrhotic patients with genotype 3 also received ribavirin. RESULTS The mean age of patients was 15.1 y, of which 12 had genotype 1, 5 had genotype 3 and 1 had an undetermined genotype. Six patients had cirrhosis and 1 was treatment experienced. Sixteen of 18 patients (89%; 95% confidence interval 74 to 100%) achieved sustained virological response at 3 mo post completion of treatment with DAAs. There was a significant reduction in alanine aminotransferase levels (p < 0.001), HCV RNA load (p < 0.001) and ferritin levels (p < 0.026) at 3 mo post completion of treatment. There were no major adverse events associated with the use of DAAs. CONCLUSIONS Generic DAAs are effective and safe in TM adolescents with HCV.

Abstract
BACKGROUND Licensure of ledipasvir/sofosbuvir for chronic hepatitis C virus (HCV) infection in adolescents was based on clinical trials on patients mainly with genotype 1. We aimed to evaluate the effectiveness and short-term safety of this newly approved antiviral in adolescents with HCV genotype 4. METHODS This was a study of 51 HCV-infected adolescents, who received the adult dose of ledipasvir/sofosbuvir, once daily for 12 weeks, and were followed-up for 12 weeks post-treatment. Laboratory tests, quantitation of HCV RNA, HCV genotyping, IL-28rs gene polymorphism and transient elastography were performed at baseline. Follow-up visits were done for blood testing and adverse events recording. RESULTS The mean age was 14.7 ± 1.5 years (11-17.5), with a male to female ratio of 1.7:1. All patients were genotype 4a, and 76.5% had the CC IL-28 gene polymorphism. About 50% gave a history of HCV-infected mother, and 31% were treatment-experienced. Liver stiffness was F0 in 72.5%, F0-F1 in 13.7% and F1-F2 in 13.7%. Adverse events were mainly abdominal pain in 72.5%, headache in 64.7% and diarrhea in 53% of patients; these were mild. A reversible increase in creatinine level with a concomitant decline in estimated glomerular filtration rate was observed in the first month of treatment. By the end of week 12, a significant decline in liver enzymes was observed. All patients achieved an early, end of treatment, and a sustained virologic response. CONCLUSIONS Adolescent patients with genotype 4 chronic HCV infection achieved a good response rate with good ontreatment tolerability for ledipasvir/sofosbuvir therapy.

Abstract
Lung transplantation can offer life-prolonging therapy to children with otherwise terminal end-stage lung disease. However, infectious complications, like those experienced by their adult counterparts, are a significant cause of morbidity and mortality. These include bacteria, viruses, and fungi that infect the patient pretransplant and those that may be acquired from the donor or by the recipient in the months to years posttransplant. An understanding of the approach to the management of each potential infecting organism is required to ensure optimal outcomes. In particular, emphasis on aggressive preoperative management of infections in pediatric patients with cystic fibrosis is important. These include multidrug-resistant Gram-negative bacteria, fungi, and Mycobacterium abscessus, the posttransplant outcome of which depends on optimal pretransplant management, including vaccination and other preventive, antibiotic-sparing strategies. Similarly, increasing the transplant donor pool to meet rising transplant demands is an issue of critical importance. Expanded-criteria donors-those at increased risk of blood-borne viruses in particular-are increasingly being considered and transplants undertaken to meet the rising demand. There is growing evidence in the adult pool that these transplants are safe and associated with comparable outcomes. Pediatric transplanters are therefore likely to be presented with increased-risk donors for their patients. Finally, numerous novel antibiotic-sparing therapeutic approaches are on the horizon to help combat infections that currently compromise transplant outcomes.
