Abstract
BACKGROUND Children and adolescents are at high risk for acute viral hepatitis (AVH), but epidemiological research focusing on them has been overshadowed by adult chronic B and C. We provide global, regional, and national estimates of the AVH burden and their trends on people under 20 years from 1990 to 2019. METHODS AVH data from Global Burden of Disease Study (GBD) 2019 was used. Incidence and disability-adjusted life years (DALYs) were calculated, analyzing trends with estimated annual percentage change (EAPC) and Joinpoint regression. RESULTS In 2019, 156.39 (95% uncertainty interval 145.20-167.16) million new cases of AVH were reported among children and adolescents globally, resulting in 1.98 (1.50-2.55) million DALYs. Incidence rates for young children (< 5 years), older children (5-9 years), and adolescents (10-19 years) were 12,799 (11,068-14,513), 5,108 (4829-5411), and 3020 (2724-3339) per 100,000 population, respectively. The global AVH incidence displayed a linear decline with an EAPC of - 0.66 (- 0.68 to - 0.65). High-incidence regions included sub-Saharan Africa, Oceania, South Asia, and Central Asia, with India, Pakistan, and Nigeria facing the greatest burden. Leading causes were hepatitis A, followed by hepatitis E, B, and C. All hepatitis types showed declining trends, especially hepatitis B. Furthermore, we confirmed the association between the AVH incidence and the socioeconomics, vaccine, and advanced liver diseases. CONCLUSION Effective vaccines and treatments for hepatitis B and C offer eradication opportunities. Broadening diagnostic and therapeutic coverage is vital to address disparities in service provision for children and adolescents.

Abstract
INTRODUCTION With the introduction of highly effective and safe therapies with next-generation direct-acting antivirals (DAAs), that act without interferon, hepatitis C virus (HCV) infection remains the only treatable chronic infectious disease. AREAS COVERED The review aims to provide an overview of the therapy revolution with a description of specific DAAs, their mechanisms of action, a summary of the safety and efficacy of specific regimens, and a discussion of populations requiring special therapeutic approaches. EXPERT OPINION DAAs are highly effective, safe, and easy to use. However, challenges such as access to health services and loss of patients from the cascade of care, especially in groups disproportionately affected by HCV infection, such as substance abusers, make it difficult to achieve the WHO's goal of HCV elimination. The proposed strategy to combat these difficulties involves a one-step approach to diagnosing and treating the infection, the availability of long-lasting forms of medication, and the development of an effective vaccine. The aforementioned opportunities are all the more important as the world is facing an opioid epidemic that is translating into an increase in HCV prevalence. This phenomenon is of greatest concern in women of childbearing age and in those already pregnant due to treatment limitations.

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.

Clin Ther 2024; 46:e12-e22. [PMID: 37925363 DOI: 10.1016/j.clinthera.2023.10.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 10/08/2023] [Accepted: 10/09/2023] [Indexed: 11/06/2023]
Abstract
PURPOSE Children with hematological malignancies and chronic hepatitis C virus (HCV) infection are at a higher risk for rapid progression of liver disease and malignancy relapse due to multiple hepatitis flares and chemotherapy interruption. They are therefore potential candidates for microelimination of HCV infection. This study aimed to assess the effect of acute lymphoblastic leukemia (ALL) on the pharmacokinetic (PK) profile of direct-acting antivirals, namely ledipasvir/sofosbuvir (LDV/SOF) and the SOF major metabolite GS-331007. METHODS This was a 24-week, prospective, controlled, open-label, 2-arm PK study of patients receiving 45/200 mg once-daily LDV/SOF orally for 12 weeks. Eligible patients were HCV-RNA-positive, treatment-naive children aged 6 to <12 years and/or weighing 17 to <35 kg with genotype 4 chronic HCV infection without cirrhosis. The primary efficacy and safety end points were the achievement of sustained virologic response for all patients with absence of any adverse events leading to permanent discontinuation of the study drug. Steady-state noncompartmental analysis was performed to determine the PK parameters of SOF, GS-331007, and LDV as the primary PK outcome. Dose suitability was based on the 90% CI of exposure geometric mean ratio percentage within 50% to 200% compared with adults. FINDINGS Ten HCV-infected children with ALL (chemotherapy treatment group) and 12 eligible children with no malignancy (control group) were enrolled and completed the study period. All 22 patients achieved the sustained virologic response with no adverse events leading to interruption or permanent discontinuation of the study drug. Compared with the control group, the ALL group patients had similar SOF, GS-331007, and LDV exposure. Compared with adults, the AUCτ of GS-331007 was lower and the AUCτ and Cmax,ss of SOF and the Cmax,ss of LDV were modestly higher in the ALL group (acceptance limit, 50%-200%). However, the observed efficacy and favorable safety profile made these changes not clinically significant. IMPLICATIONS Weight-based dosing of LDV/SOF (45/200 mg) is highly effective and safe among genotype 4 HCV-infected children weighing 17 to <35 kg and diagnosed with ALL undergoing maintenance chemotherapy. The similarity in the drug exposure, efficacy, and safety clinical end points between patients with and without hematological malignancy support their therapeutic equivalence. Further studies with a larger sample size may be required to confirm the safety of LDV/SOF in patients with ALL and to recommend appropriate dosing in children with hematological malignancies, if needed.

Abstract
BACKGROUND AND AIMS The aim of this non-commercial, open-label, real-life, non-randomized clinical trial was to analyse the efficacy and safety of a pangenotypic regimen sofosbuvir/velpatasvir (SOF/VEL) in patients aged 6-18 years with chronic hepatitis C virus (HCV) infection. METHODS Fifty patients qualified for the 12-week treatment were divided into two weight groups: 15 children weighting between 17 and <30 kg received a fixed dose of 200/50 mg of SOF/VEL (tablet) once daily, and 35 patients weighting ≥30 kg were treated with 400/100 mg SOF/VEL. The primary endpoint of the study was efficacy defined as sustained viral response (undetectable HCV RNA using an real-time polymerase chain reaction method) at 12 weeks posttreatment (SVR12). RESULTS Median age of the participants was 10 (IQR 8-12) years, 47 were infected vertically, and 3 patients were previously ineffectively treated with pegylated interferon and ribavirin. Thirty-seven participants were infected with HCV genotype 1, 10 with HCV genotype 3 and the remaining 3 with genotype 4. There was no case of cirrhosis. SVR12 was 100%. Thirty-three reported adverse events (AEs) were considered related to the administration of SOF/VEL, all of them were mild or moderate. Children presenting with AEs were older compared to these without AEs: 12 (9.5-13) versus 9 (IQR 8-11) years (p = 0.008). CONCLUSIONS Results of the PANDAA-PED study indicated a 100% effectiveness of a 12-week therapy with SOF/VEL in children aged 6-18 years with chronic HCV infection and its good safety profile, in particular in younger patients.

Abstract
OBJECTIVES In children with hematological malignancies, chronic hepatitis C virus (HCV) infection has been associated with more rapid liver disease progression and higher risk of malignancy relapse due to chemotherapy interruption. We evaluated the safety and efficacy of ledipasvir-sofosbuvir for 12weeks in these patients. METHODS In a phase 2, open-label study, at one site in Egypt, patients ages 12-<18years with chronic HCV genotype 1 or 4 infection undergoing maintenance chemotherapy for hematological malignancies received ledipasvir-sofosbuvir (90 mg/400 mg) once daily for 12weeks. The efficacy endpoint was sustained virologic response 12 weeks after treatment (SVR12). Safety was assessed by the incidence of adverse events and clinical and laboratory data, including HCV flares defined as alanine aminotransferase >3-fold increase from Day 1 and HCV RNA elevation >1 × log10 from Day 1. RESULTS Of the 19 adolescents enrolled and treated, median age was 14 years (range 12-17), 84% (16/19) were male, and all had HCV genotype 4 and were HCV treatment naive. All patients completed treatment and achieved SVR12 (19/19, 100%, 95% confidence interval, 82-100). Common adverse events were pyrexia (5/19, 26%), diarrhea (4/19, 21%), and headache (4/19, 21%). Three patients experienced serious adverse events of pneumonia (two patients), and osteoarthritis and diarrhea (one patient); none were considered related to study drug. No patient experienced HCV flares. CONCLUSIONS Ledipasvir-sofosbuvir was well-tolerated and efficacious in adolescents with chronic HCV genotype 4 and leukemia undergoing maintenance chemotherapy. These data support the use of this interferon and ribavirin-free regimen in adolescents with hematological malignancies.

Abstract
Microelimination targets specific subpopulations and/or geographic settings for hepatitis C virus (HCV) elimination. This review reports on global HCV microelimination literature published from 2013 to 2020. Data were extracted from publications to report a score based on the four key components defining microelimination. Sustained virologic response (SVR) and treatment initiation proportions were calculated for each manuscript and grouped means of these estimates were compared depending on microelimination score and care setting. A total of 83% of the studies were from high-income settings and mainly included people who use drugs or those incarcerated. Among manuscripts, 18 had "low" microelimination scores, 11 had "high" scores, and the differences in mean proportion who initiated treatment and achieved SVR between low and high score groups were statistically significant. Microelimination can be a useful complementary strategy for driving engagement in HCV treatment and cure. Our analysis suggests that adhering to more of the core microelimination components can improve outcomes. This study is registered with Prospero, registration identification: CRD42020175211.

Abstract
BACKGROUND Sofosbuvir (SOF)/daclatasvir (DCV) is the direct-acting antiviral regimen of choice in many low- and middle-income countries for curative treatment of chronic hepatitis C virus (HCV) infection in adults, but data on the use of DCV in children are lacking. We performed a population pharmacokinetic (PK) analysis to predict DCV exposure in children treated with available adult formulations. METHODS DCV concentration data from HCV-infected adolescents receiving SOF/DCV [400/60 mg, once daily (OD)] who participated in a PK study in Egypt were used for model development. PK parameters were estimated using a population approach. Monte Carlo simulations were run for virtual children weighing 10 to <35 kg receiving 60 or 30 mg OD, and DCV exposures were compared with adults ranges. RESULTS Seventeen HCV-infected adolescents (13 males) provided 151 DCV concentrations. Median (range) age was 14 (11-18) years and weight 50 (32-63) kg. In these adolescents receiving 60 mg DCV, median (interquartile range) DCV area under the concentration time curve 0 to 24 hours, maximum concentrations, and minimum concentrations were 11,130 (8140-14,690) ng·h/mL, 1030 (790-1220) ng/mL and 130 (110-220) ng/mL, respectively, compared with 10,343 (7661-14,095) ng·h/mL, 1132 (876-1518) ng/mL and 110 (55.7-192) ng/mL predicted in children 10 to <35 kg receiving 30 mg. The proportion of children with DCV exposures above the adult range rapidly increased for children <30 kg using 60 mg OD, similarly for children 10-14 kg using 30 mg. CONCLUSIONS DCV 30 mg OD was predicted to achieve effective and safe exposures in children 14 to <35 kg, perhaps down to 10 kg. These results should be validated clinically. Low-cost available adult DCV formulations together with approved pediatric doses of SOF would expand global access to HCV treatment for children.

Abstract
Introduction: Sofosbuvir/velpatasvir is a combination of direct-acting antivirals with pangenotypic activity for treatment of chronic hepatitis C virus infection. It was approved in 2020 for use in children aged 6-17 years and in June 2021 by the United States Food and Drug Administration for the age group 3-5 years.Areas covered: A literature search of PUBMED and EMBASE was conducted on April 30th and updated on June 10th. Other citations were identified in references of available literature and from ClinicalTrials.gov. The aim of the present research was to outline and discuss the pharmacokinetics, clinical efficacy, tolerability and safety of sofosbuvir/velpatasvir, exploring its actual and potential use in children and adolescents with chronic hepatitis C virus infection.Expert opinion: Five combinations of direct-acting antivirals, of whom three with pangenotypic activity, are now approved for children. No major differences in efficacy and safety profile have been described. Limited access to treatment still is a major issue, especially in low and middle-income countries.

Real-Life Experience with Ledipasvir/Sofosbuvir for the Treatment of Chronic Hepatitis C Virus Infection with Genotypes 1 and 4 in Children Aged 12 to 17 Years-Results of the POLAC Project. J Clin Med 2021; 10:jcm10184176. [PMID: 34575286 PMCID: PMC8465669 DOI: 10.3390/jcm10184176] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2021] [Revised: 09/13/2021] [Accepted: 09/14/2021] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Available real-world data on the efficacy and safety of ledipasvir/sofosbuvir (LDV/SOF) in pediatric patients are limited. In this prospective, open-label, single-center study, we aimed to present our real-life experience with a fixed dose of LDV/SOF (90/400 mg) for the treatment of chronic hepatitis C (CHC) genotypes 1 and 4 in children aged 12 to 17 years. METHODS We analyzed intention-to-treat (ITT) and per-protocol (PP) rates of sustained virological response (SVR), defined as undetectable HCV viral load at posttreatment week 12, in 37 participants treated with LDV/SOF according to the HCV genotype, baseline liver fibrosis, duration of treatment, and experience of the previous ineffective antiviral treatment. There were 32 patients infected with genotype 1 and 5 with genotype 4. Fourteen (38%) participants were treatment-experienced, two were coinfected with HIV, and three were cirrhotic. Two patients qualified for 24 weeks of therapy, and the remaining 35 received 12 weeks of LDV/SOF treatment. RESULTS The overall ITT SVR12 rate was 36/37 (97%). One patient was lost to follow-up after week 4 of therapy when his HCV RNA was undetectable. All 36 patients who completed the full protocol achieved SVR (36/36, 100%). PP analyses of SVR12 rates according to the HCV genotype, baseline liver fibrosis, duration of the treatment, and previous ineffective treatment were all 100%. A significant decrease in aminotransferase serum levels was observed in the subsequent weeks of the treatment and at SVR assessment compared to baseline. No serious adverse events were reported. CONCLUSIONS The results of this study confirm previous observations of a suitable efficacy and safety profile of LDV/SOF for the treatment of CHC genotypes 1 and 4 in adolescents.

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

Progress and Barriers Towards Elimination of Chronic Hepatitis C in Children. KLINISCHE PADIATRIE 2020; 233:211-215.

Abstract
Chronic hepatitis C (CHC) is a global health burden. Mother-to-child transmission (MTCT) accounts for most HCV infections in pediatric patients. Spontaneous viral clearance may occur in early childhood but is uncommon thereafter. Infection is usually asymptomatic during childhood, although without an effective treatment, vertically infected children may develop serious liver complications including cirrhosis and hepatocellular carcinoma in adulthood. Despite the lack of vaccine against hepatitis C and effective post-exposure methods of prevention of MTCT, treatment with direct-acting antiviral agents (DAAs) raised the prospect of eliminating HCV on a population level. Highly effective, well-tolerated, oral, and interferon-free regimens of short duration have revolutionized treatment of CHC. However, access to these therapies might be limited because of its high cost. In this review, we provide the current state of knowledge on the epidemiology, testing, monitoring and treating of HCV in children. We outline the remaining gaps in therapy and barriers to disease eradication.
