Hepatitis C Virus-Pediatric and Adult Perspectives in the Current Decade

Abstract

Hepatitis C virus (HCV) infects both pediatric and adult populations and is an important cause of chronic liver disease worldwide. There are differences in the screening and management of HCV between pediatric and adult patients, which have been highlighted in this review. Direct-acting antiviral agents (DAA) have made the cure of HCV possible, and fortunately, these medications are approved down to three years of age. However, treatment in the pediatric population has its own set of challenges. The World Health Organization (WHO) has made a pledge to eliminate HCV as a public health threat by 2030. Despite this, HCV continues to remain a global health burden, leading to cirrhosis as well as hepatocellular carcinoma, and is a reason for liver transplantation in the adult population. Although rare, these complications can also affect the pediatric population. A variety of new technologies t have become available in the current era and can advance our understanding of HCV are discussed. Artificial intelligence, machine learning, liver organoids, and liver-on-chip are some examples of techniques that have the potential to contribute to our understanding of the disease and treatment process in HCV. Despite efforts over several decades, a successful vaccine against HCV has yet to be developed. This would be an important tool to help in worldwide efforts to eliminate the virus.
