Updates on Chronic HBV: Current Challenges and Future Goals

AbstractPurpose of ReviewChronic HBV (CHB) remains a global public health problem with over 257 million people chronically infected worldwide. Without appropriate management, 20% of individuals infected with CHB will die from complications of cirrhosis, liver failure, or hepatocellular carcinoma (HCC). Despite an effective vaccination to prevent infection, HBV has yet to be successfully eradicated globally. Current treatments can only control and suppress the virus but cannot cure. Updates in the management of chronic HBV will be reviewed, including latest treatments and treatment strategies as well as potential curative therapeutic agents in clinical trial.Recent FindingsA new nucleotide analogue drug, tenofovir alafenamide fumarate (TAF), has been added to the HBV therapeutic armamentarium. A more potent drug showing non-inferiority, TAF has shown to improve renal and bone laboratory safety parameters compared to TDF. In addition, new treatment recommendations have been made for both general and special populations including pregnancy and HBV reactivation. There is growing data supporting the importance of antiviral therapy in patients with advanced liver disease and liver decompensation which has resulted in improved outcomes. In addition, at least 30 potential therapeutics are in clinical trials in the pursuit of curative treatments for chronic HBV with the goal of “functional cure.”SummaryCHB remains a global public health problem with complications including cirrhos...
