Type 2 Diabetes (T2D)
Conditions
Brief summary
The prevalence of fatty liver disease (NAFLD: Non-Alcoholic Fatty Liver Disease or to a more severe degree NASH: Non-Alcoholic SteatoHepatitis) reached 40-70% in subjects with type 2 diabetes (T2D). NAFLD can be easily detected by performing a hepatic ultrasonography. The presence of a NAFLD is positively correlated with the severity of insulin resistance and dysglycemia in this population. The presence of NAFLD worsens the prognosis of T2D with an increased cardiovascular risk. This hepatic impairment would also increase the risk of microvascular complications, especially nephropathy. Conversely, T2D increases the risk of transition from NAFLD to NASH and then to hepatic fibrosis and its related complications (cirrhosis, hepatocellular carcinoma). The risk of progression of liver steatosis to fibrosis is also more important as diabetes and insulin resistance are more severe. In addition to diabetes and insulin resistance, other risk factors are associated with more severe liver damage such as changes in microbiota. Indeed, it has already been described a smaller amount of bacteroides in the microbiota of subjects with T2D and the most severe hepatic impairment. The treatment of NAFLD/NASH is poorly codified without approved drugs in this indication, while many phase 3 trials with candidate drugs are undergoing. Life-style measures (physical activity and low carbohydrate/calorie diet) can limit the progression from NAFLD to more severe liver fibrosis. Some bariatric surgery studies have also shown good results in this situation. Pharmacological interventions are also reported with proven efficacy of pioglitazone, vitamin E and orlistat. The OPT2MISE study has recently shown the superiority of insulin pump (or continuous sub-cutaneous insulin infusion: CSII) compared to multiple daily insulin injections (MDI) to improve glycemic control in a population of patients with T2D in failure of well-titrated MDI. In addition, treatment with CSII showed a 45% decrease in insulin resistance (assessed by HOMA-IR) in a population of newly diagnosed T2D. In light of these data, investigators hypothesize that the introduction of insulin pump treatment in a population of subjects with T2D and NAFLD, by improving insulin sensitivity, could reduce fatty liver content compared to standard MDI treatment.
Interventions
