Development and Regression of Cirrhosis

Area of Science:

• Hepatology and Gastroenterology
• Cellular Biology
• Immunology

Background:

• Liver cirrhosis results from chronic injury, disrupting normal liver architecture.
• Key mechanisms include neo-angiogenesis, necro-inflammation, extracellular matrix changes, and innate immunity.
• While fibrosis progression is influenced by individual factors, regression is also possible.

Purpose of the Study:

• To highlight that cirrhosis is a dynamic, not static, condition.
• To emphasize the limitations of current classifications in assessing disease evolution.
• To underscore the potential for fibrosis regression with effective treatments for chronic liver diseases (CLDs).

Main Methods:

• Review of current understanding of cirrhosis pathogenesis.
• Analysis of factors influencing fibrosis progression and regression.
• Evaluation of existing methods for assessing fibrosis and cirrhosis.

Main Results:

• Cirrhosis is a dynamic process with potential for regression, particularly with etiology-driven therapies.
• Current scoring systems inadequately capture the evolving nature of advanced CLDs.
• Cessation of the causative agent does not always prevent disease progression or complications.

Conclusions:

• Cirrhosis is a dynamic process, and current assessments are insufficient.
• Effective CLD treatment offers potential for fibrosis regression.
• Development and validation of new markers are crucial for evaluating fibrosis regression.
