Zusammenfassung
Die nichtalkoholische Fettlebererkrankung (NAFLD) und insbesondere die nichtalkoholische Steatohepatitis (NASH) stellen nicht nur Risikofaktoren für Leberfibrose, Leberzirrhose und das hepatozelluläre Karzinom dar, sondern sind auch stark mit der Insulinresistenz und dem Typ-2-Diabetes assoziiert. Dies liegt wahrscheinlich daran, dass in der Pathogenese dieser Erkrankungen gemeinsame Mechanismen von Bedeutung sind. Darüber hinaus sagen NAFLD und NASH die Erkrankungswahrscheinlichkeit für Typ-2-Diabetes, aber auch für die Atherosklerose voraus, was eine kausale Rolle der Fettleber in der Pathogenese dieser Erkrankungen impliziert. Diese Hypothese wird durch neue Ergebnisse unterstützt, die durch Genotypisierung und Phänotypisierung bei Risikopersonen gewonnen wurden. Die genaue Erforschung der beteiligten Mechanismen wird in der Zukunft wichtige neue Erkenntnisse bringen, die für die Prävention und Therapie dieser Erkrankungen bedeutsam sein werden.
Abstract
Nonalcoholic fatty liver (NAFL) and particularly nonalcoholic steatohepatitis (NASH) are not only risc factors for liver fibrosis, liver zirrhosis and hepatocellular carcinoma, but are also strongly associated with insulin resistance and type 2 diabetes. This is probably due to the fact that the same mechanisms are operative in the pathogenesis of these diseases. In addition fatty liver predicts incident type 2 diabetes, but also atherosclerosis, indicating a causal role of fatty liver in the pathogenesis of these diseases. This hypothesis is supported by novel findings deriving from translational research involving precise genotyping and phenotyping strategies in humans. The precise investigation of mechanisms involved will deliver new knowledge which may be important for the prevention and therapy of these diseases.
