Influence of Diabetic Control on the Degree of Liver Fibrosis Assessed by Non-invasive Scores in Patients Followed in Diabetology

Metabolic steatopathy (nonalcoholic fatty liver disease or NAFLD) has seen its prevalence soar in recent years that it is now the leading cause of chronic liver disease in developed countries, surpassing viral and alcoholic etiologies and affecting approximately 25% of the world's population. This growth is explained by a change in eating habits, lifestyle, and the increase in the prevalence of obesity in the general population. This hepatopathy evolves in successive stages in a slow and insidious manner: from simple fatty overload in the liver (NALF, steatosis), to steatosis plus hepatic inflammation (NASH - "nonalcoholic steatohepatitis"), up to the stage of cirrhosis with all its own complications Isolated steatosis has a rather benign course, whereas the transition to NASH is associated with a high risk of general mortality and liver-related causes. NASH is the stage at which fibrogenesis accelerates with the risk of progression to cirrhosis and/or primary liver cancer. The degree of hepatic fibrosis has a major influence on the prognosis of patients with NAFLD. Specifically, the presence of fibrosis greater than or equal to 2 (F≥2) is associated with increased risk of liver events and liver-related mortality. The risk of cardiovascular events increases as early as fibrosis grade 1 (F≥1). In addition, the presence of advanced fibrosis or cirrhosis (F≥3) greatly increases the risk of developing hepatocellular carcinoma, and patients require biannual monitoring by liver ultrasound. Systematic screening of diabetic patients with advanced fibrosis is necessary to establish specific surveillance. Non-invasive scores have been developed to assess the degree of liver fibrosis in patients with NAFLD. Among these scores, FIB4 ("Score Fibrosis-4") has the advantage of being easy to use in routine practice with good diagnostic performance for liver fibrosis in patients with NAFLD. A FIB4 value ≤ 1.3 has a negative predictive value of 90% for the diagnosis of severe fibrosi
