Role of leptin in progression of alcoholic and non-alcoholic steatohepatitis

Non-alcoholic steatohepatitis

[Non-alcoholic fatty liver disease and non-alcoholic steatohepatitis].

Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) are the hepatic manifestations of the metabolic syndrome. Since the prevalence of obesity and consequently of the metabolic syndrome is steadily increasing, the different types of NAFLD are nowadays the most common cause of liver injury in North America. The development of NASH and fatty liver cirrhosis occurs af...

Non-alcoholic steatohepatitis in children.

Non-alcoholic steatohepatitis (NASH) is an important liver disease in children; it can cause cirrhosis in children. The disease mechanism involves hepatic insulin resistance with hyperinsulinemia and changes in certain adipocytokines and inflammatory mediators. The differential diagnosis of childhood NASH includes metabolic disorders, drug hepatotoxicity, and alcoholic hepatitis in adolescent p...

Common pathogenic mechanism in development progression of liver injury caused by non-alcoholic or alcoholic steatohepatitis.

This review showed the common pathogenic mechanism in the development of non-alcoholic or alcoholic steatohepatitis. In particular, we describe the role of innate immune system and oxidative stress caused by gut-derived endotoxin. Gut-derived endotoxin plays an important role in alcoholic liver injury. It was reported that acute ethanol administration reduced activation of Kupffer cells. It is ...

Dual role of protein tyrosine phosphatase 1B in the progression and reversion of non-alcoholic steatohepatitis

OBJECTIVES Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in Western countries. Protein tyrosine phosphatase 1B (PTP1B), a negative modulator of insulin and cytokine signaling, is a therapeutic target for type 2 diabetes and obesity. We investigated the impact of PTP1B deficiency during NAFLD, particularly in non-alcoholic steatohepatitis (NASH). METHODS NA...
