title: Nonalcoholic fatty liver disease as a contributor to hypercoagulation and thrombophilia in the metabolic syndrome.
abstract: Nonalcoholic fatty liver disease (NAFLD), comprising its whole spectrum of conditions ranging from simple steatosis to steatohepatitis (nonalcoholic steatohepatitis; NASH) and cirrhosis, is the most frequent liver disease in developed countries and is now regarded as the liver manifestation of the metabolic syndrome. Several studies indicate that NAFLD, especially in its necro-inflammatory form (NASH), is associated with a systemic proinflammatory/prothrombotic state, independently of shared metabolic risk factors. This suggests that NAFLD/NASH is not simply a marker of the proinflammatory/prothrombotic state in the metabolic syndrome but is actively involved in its pathogenesis, possibly through the systemic release of proinflammatory and procoagulant factors from the steatotic liver (C-reactive protein, plasminogen activator inhibitor-1, interleukin-6, fibrinogen, and other proinflammatory cytokines). The clinical impact of NAFLD on the proinflammatory/prothrombotic risk profile deserves particular attention in view of the implications for screening and surveillance strategies in the growing number of patients with NAFLD.
