Summary
Current hepatitis B virus (HBV) treatments cannot eliminate the virus. New strategies focus on silencing or eliminating cccDNA to cure HBV infection, with clinical data expected within five years.
Area of Science:
- Hepatology
- Virology
- Immunology
Background:
- Hepatitis B virus (HBV) infection is a global health concern, often leading to hepatocellular carcinoma.
- Current antiviral therapies, including interferons and small molecules, control but do not eliminate HBV.
- Significant challenges remain in eradicating HBV from infected cells, particularly the persistent cccDNA form.
Purpose of the Study:
- To review current treatments for hepatitis B virus (HBV) infection.
- To examine novel therapeutic strategies aimed at silencing or eliminating HBV cccDNA for a potential cure.
- To highlight emerging preclinical and clinical approaches for HBV eradication.
Main Methods:
- Review of existing literature on HBV antiviral agents and therapies.
- Analysis of recent advancements in HBV therapeutic strategies, including gene-editing and immunological approaches.
- Examination of ongoing preclinical and clinical trials for novel HBV treatments.
Main Results:
- Existing treatments effectively control HBV but do not achieve viral elimination.
- Emerging strategies like capsid effectors, CRISPR/Cas9, TALENs, siRNA, and immunological approaches show promise for cccDNA targeting.
- Combination therapies are likely necessary for successful HBV elimination and prevention of viral rebound.
Conclusions:
- Eliminating HBV cccDNA is the key to achieving a functional cure for chronic hepatitis B.
- A combination of novel therapeutic modalities will likely be required for effective HBV eradication.
- Clinical data within the next five years will be crucial for assessing the safety and feasibility of these new approaches globally.

Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Group therapy is a sociocultural approach to psychological treatment, where individuals with shared psychological challenges come together under the guidance of a mental health professional. This therapeutic modality offers unique opportunities for individuals to connect, share, and grow within the context of a supportive group. By fostering mutual understanding and collaboration, group therapy can address a range of psychological concerns effectively, often complementing or surpassing the...

Behavior therapy incorporates diverse techniques rooted in classical conditioning principles to address maladaptive behaviors and anxiety disorders. These methods aim to reduce avoidance behaviors, foster adaptive coping mechanisms, and alter associations between stimuli and responses, making them effective in a wide range of therapeutic contexts.

The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

Cognitive therapy, pioneered by Aaron T. Beck in the 1960s, is a structured approach to addressing psychological distress by focusing on the influence of thoughts on emotions and behaviors. All cognitive therapies involve the basic assumption that human beings have control over their feelings, and that how individuals feel about something depends on how they think about it. Unlike psychoanalytic methods that delve into unconscious processes or humanistic approaches emphasizing...

Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early...
