Abstract

Purpose of Review

Chronic Hepatitis B Virus (HBV) Infection is a major global health burden. Currently, a curative therapy does not exist; thus, there is an urgent need for new therapeutical options. Viral elimination in the natural course of infection results from a robust and multispecific T and B cell response that, however, is dysfunctional in chronically infected patients. Therefore, immunomodulatory therapies that strengthen the immune responses are an obvious approach trying to control HBV infection. In this review, we summarize the rationale and current options of immunological cure of chronic HBV infection.

Recent Findings

Recently, among others, drugs that stimulate the innate immune system or overcome CD8+ T cell exhaustion by checkpoint blockade, and transfer of HBV-specific engineered CD8+ T cells emerged as promising approaches.

Summary

HBV-specific immunity is responsible for viral control, but also for immunopathogenesis. Thus, the development of immunomodulatory therapies is a difficult process on a thin line between viral control and excessive immunopathology. Some promising agents are under investigation. Nevertheless, further research is indispensable in order to optimally orchestrate immunostimulation.

Medication Non-adherence among Liver Transplant Recipients

Live Webinar | 27-06-2024 | 18:00 (CEST)

Keynote webinar | Spotlight on medication adherence

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
