The glycemic profile in patients with non-alcoholic steatohepatitis and type 2 diabetes depending on diabetic kidney disease
Abstract
Background. State of carbohydrate metabolism and severity of insulin resistance in the comorbid course of non-alcoholic steatohepatitis (NASH) and diabetic kidney disease (DKD) in patients with type 2 diabetes mellitus (DM2) is due to the cascade of possible transformation of NASH into liver cirrhosis. The purpose is to study the interaction of changes in glucose and insulin homeostasis, the degree of insulin resistance and insulin sensitivity, the degree of hemoglobin glycosylation on the clinical course of NASH associated with DM depending on the presence of DKD and its stage. Materials and methods. One hundred and eight patients with NASH and comorbid DM2 were examined. The average age of patients was 58.2 ± 6.1 years. There were 63 women (58.3 %) and 45 men (41.7 %). Depending on the presence of DKD, 4 groups of patients were formed, who were randomized by age, sex, activity of cytolytic syndrome. The comparison group consisted of 30 healthy individuals of the appropriate age and sex. The degree of hepatic steatosis and its nature were determined using SteatoTest, ASH and NASH-Test kits (BioPredictive, France). The stage of liver fibrosis was determined using FibroTest (BioPredictive, France), a set of markers for quantitative biochemical evaluation of fibrosis. Results. In patients with NASH, DM2 and DKD stage I–II, we found a significant decrease in serum albumin by 9.0 % (p < 0.05); glomerular filtration rate (GFR) and urine albumin, on the contrary, increased significantly, by 1.5 times (p < 0.05) compared to those in the control group, which indicates the phenomenon of hyperfiltration and is specific to the initial stage of DKD. When NASH is combined with DM2 and DKD stage III, a significant decrease in serum albumin by 1.2 times (p < 0.05) is reported; GFR and albuminuria were significantly increased, by 1.4 and 11.7 times (p < 0.05), respectively, compared to the control group. In patients with NASH, DM2 and DKD stage IV, we found a significant decrease in serum albumin by 1.4 times (p < 0.05), it was significantly increased by 30.2 times (p < 0.05) compared to the indicator in the control group, and the GFR, on the contrary, was significantly reduced by 1.7 times (p < 0.05), which indicates the progression of DKD. Conclusions. Disorders of glucose homeostasis due to insulin resistance are one of the probable risk factors for the progression of non-alcoholic steatohepatitis and type 2 diabetes mellitus in the presence of stage I–IV diabetic kidney disease.
