Chronic Hepatitis C Infection in Children: Current Treatment and New Therapies

Using Preventive Health Alerts in the Electronic Health Record Improves Hepatitis C Virus Testing Among Infants Perinatally Exposed to Hepatitis C

BACKGROUND

Perinatal exposure to hepatitis C virus (HCV) is a major public health issue, and poor testing rates leave many children with infection unidentified. We sought to use the electronic health record (EHR) to promote guideline-directed HCV testing among infants born to mothers with HCV infection in an urban, safety-net hospital system.

METHODS

Our study population was identified using our EHR database, Epic. Children were included in the study if they had perinatal HCV exposure, were 18 months to 18 years of age and had at least 1 encounter in a primary or urgent care clinic during the study period. Our study included retrospective (October 2011 to February 2015) and prospective (February 2015 to May 2018) arms. Our EHR-based intervention was initiated in the prospective arm and recommended a one-time HCV antibody test at or after the age of 18 months using a health maintenance reminder. The health maintenance reminder activated a point-of-care alert and a linked HCV testing order set in all prespecified encounters during the intervention period.

RESULTS

Median time to appropriate HCV testing decreased from 96.2 months preintervention to 9.1 months postintervention (P < 0.0001), and rate of completed antibody testing increased from 14% to 61% (P < 0.0001).

CONCLUSIONS

Among children with perinatal HCV exposure, using a point-of-care alert within the EHR significantly increased the HCV antibody testing rate in accordance with American Academy of Pediatrics (AAP) recommendations. More effective EHR-based interventions combined with increased provider awareness of appropriate HCV testing in perinatally exposed infants is imperative.

A Path to Ending Hepatitis C in Ethiopia: A Phased Public Health Approach to Achieve Micro-Elimination

Ethiopia's hepatitis C virus (HCV) prevalence is predicted to rise by 2030. To halt this increasing trend, a suitable approach to the elimination of HCV is needed. This review explores the current status, challenges, and opportunities and outlines a strategy for the micro-elimination approach in Ethiopia. I searched PubMed and EMBASE using combined Medical Subject Heading databases for the literature on HCV micro-elimination. A phased public health approach to HCV micro-elimination, including preparation/capacity building (phase I), implementation (phase II), and rollout and scale-up (phase III), targeting people living with HIV, prisoners, chronic hepatitis and cancer patients, blood donors, and pregnant women is a pragmatic strategy to Ethiopia. This can be implemented at general and tertiary care referral hospitals with a future scale-up to district hospitals through task-shifting by training general practitioners, nurses, laboratory technologists, and pharmacists. Availability of the highly effective direct-acting antivirals (DAAs) can be ensured by expanding the existing program that provides highly subsidized DAAs through an agreement with Gilead Sciences, Inc. and eventually aiming at domestic generic manufacturing. The significant enablers to HCV micro-elimination in Ethiopia include the control of healthcare-associated HCV infection, blood safety, access to affordable testing and pan-genotypic DAAs, task-shifting, multisectoral partnership, and regulatory support. General population-based HCV screening and treatment are not cost-effective for Ethiopia because of high cost, program complexity, and disease epidemiology.

[Ledipasvir/sofosbuvir combination for chronic hepatitis C infection in children and adolescents]

INTRODUCTION

Hepatitis C virus infection is world health problem. The aim of this study was to assess the safety and efficacy of ledipasvir/sofosbuvir combination in chronic Hepatitis C Virus (HCV) genotype 1 and 4 infection in paediatric patients.

METHODS

Eligible patients to be treated with ledipasvir/sofosbuvir were patients from 6 to 18 years old with a chronic HCV genotype 1 or 4 infection. The duration and doses of antiviral drugs were changed depending on patient age, fibrosis stage, and PEGylated interferon+ribavirin experience status. The primary efficacy endpoint was the percentage of patients with a sustained virological response 12 weeks post-treatment.

RESULTS

A total of nine patients (7 males) with a median age of 14.8 years (8.48-17.91) were treated with ledipasvir/sofosbuvir combination. Five patients received previous treatment with PEGylated interferon+ribavirin during a median of 8.5 months (3-12 months). Eight patients had some degree of fibrosis (1 patient presented with F1, three patients F2, 2 patients F3, and 2 patients F4). The median pre-treatment viral load was 6.2 Log [5.9-6.8] with the HCV RNA becoming negative six weeks after starting the treatment in 100% of the patients. All patients maintained a sustained viral response at 12 weeks. Three patients (33.3%) had some type of adverse effect (2 headache and one oral thrush). The median post-treatment follow-up was 24 weeks (12-104).

CONCLUSIONS

Treatment with ledipasvir/sofosbuvir in paediatric patients with chronic HCV infection genotype 1 and 4 is safe and effective with SVR12 and similar to those reported in adults.
