Background And Aims:
It is unclear if improving glycemic control in persons with type 2 diabetes (T2D) also has liver-related effects. We aimed to evaluate if a personalized treatment program associates with improvement of liver-related parameters in persons with advanced T2D in a real-life setting.
Methods:
Persons with advanced T2D underwent a 4-day personalized treatment program, with the aim of improving glycemic control by dietary advice, instructions on how to achieve optimal glucose control and individualized dosage of medications. Transient elastography was used to estimate liver steatosis and fibrosis. Persons with liver diseases other than non-alcoholic fatty liver disease (NAFLD) were excluded. After 3 months, study participants were offered re-examination.
Results:
Ninety-one persons were included. Of these, 75 persons (82%) had controlled attenuation parameter (CAP) measurements of acceptable quality at baseline. Of these, 57 (76%) had NAFLD (defined as >268 dB/m). Twenty-two persons (24%) had elevated liver stiffness (>7.9 kPa), and eight (9%) had liver stiffness above 13.9 kPa, indicating advanced fibrosis. Over a median follow-up of 101 days, mean CAP in persons with NAFLD was reduced by 18.33 dB/m (P = 0.035). In persons with elevated liver stiffness, mean stiffness was reduced by 2.6 kPa (P = 0.047). In linear regression, one-unit improvement in fasting glucose (mg/dl) was associated with a decrease in hepatic steatosis with 0.48 dB/m (adjusted R2 = 0.35, P < 0.01).
Conclusion:
The prevalence of NAFLD with advanced fibrosis is high in persons with advanced T2D. Improving glycemic control through a personalized treatment program is associated with a reduction in liver steatosis and stiffness in this cohort.
Insights
Improving glycemic control in type 2 diabetes (T2D) patients through personalized programs can reduce liver steatosis and stiffness. This study shows a link between better glucose management and improved liver health in advanced T2D.
Area of Science:
- Hepatology
- Endocrinology
- Metabolic Diseases
Background:
- The impact of glycemic control on liver health in type 2 diabetes (T2D) is not fully understood.
- Non-alcoholic fatty liver disease (NAFLD) and advanced fibrosis are prevalent in individuals with advanced T2D.
Purpose of the Study:
- To investigate the association between a personalized treatment program aimed at improving glycemic control and liver-related parameters in patients with advanced T2D.
- To evaluate the real-life effectiveness of such interventions on liver steatosis and fibrosis.
Main Methods:
- A 4-day personalized treatment program focusing on diet, glucose control education, and medication adjustment was implemented for advanced T2D patients.
- Transient elastography, including controlled attenuation parameter (CAP) for steatosis and liver stiffness measurement (LSM) for fibrosis, was used.
- Exclusion criteria included liver diseases other than NAFLD; follow-up assessments were conducted after 3 months.
Main Results:
- Out of 91 participants, 75 had quality CAP measurements, with 57 (76%) diagnosed with NAFLD.
- Twenty-two participants (24%) exhibited elevated liver stiffness, and 8 (9%) had advanced fibrosis.
- A median follow-up of 101 days showed a significant reduction in mean CAP (18.33 dB/m, P=0.035) and liver stiffness (2.6 kPa, P=0.047) in relevant subgroups.
- Improved fasting glucose levels correlated with reduced hepatic steatosis (adjusted R2=0.35, P<0.01).
Conclusions:
- A high prevalence of NAFLD with advanced fibrosis exists in advanced T2D patients.
- Personalized glycemic control interventions are associated with significant improvements in liver steatosis and stiffness in this population.
- Targeting glycemic control may be a viable strategy for managing liver-related complications in T2D.
