Role of Coagulation, Inflammation and Vessels in Chronic Liver Disease

Chronic liver diseases represent a major public health problem and are responsible for more than 150,000 deaths in Europe each year. These diseases are accompanied by symptoms that profoundly alter the quality of life and mainly affect people of working age, leading to a major economic impact.

Coagulation disorders, inflammation and vascular alterations are associated with chronic liver diseases but their role in the onset and/or progression of liver diseases is still not fully understood.

A better understanding of chronic liver diseases and in particular of the factors that play a role in the onset and progression of these diseases would improve patient management and therefore have a positive impact on individuals, but also on the healthcare system and the economy.

A better understanding of chronic liver diseases and in particular of the factors that play a role in the onset and progression of these diseases would improve patient management and therefore have a positive impact on individuals, but also on the healthcare system and the economy.

The main objective is to identify the role of coagulation in the development and progression of chronic liver diseases and their complications.
