[Clinical and prognostic value of metabolic disorders in non-alcoholic fatty liver disease]

AIM

A comprehensive assessment of metabolic parameters in patients with non-alcoholic fatty liver disease and based on them the development of prognostic criteria for the development of liver fibrosis.

MATERIALS AND METHODS

288 patients with non-alcoholic fatty liver disease at the stage of steatosis were examined. The patients underwent ultrasound examination of the hepatobiliary system using the SONIX OP apparatus (Canada), the FibroMax test, and liver elastography using the AIXPLORER apparatus (France). The parameters of anthropometry, lipid spectrum, protein and pigment metabolism, cytolysis, cholestasis, bilirubin, insulin in the blood serum were evaluated. The methods of statistical forecasting are used.

RESULTS

The clinical picture in patients with non-alcoholic fatty liver disease at the stage of steatosis was nonspecific and was due to the presence of concomitant diseases of the digestive system and the cardiovascular system. A kettle index of up to 30 was observed in 26.5% of patients, from 30 to 34.9 in 37.5%, from 35 to 39.9 in 29.7% of patients, more than 40 in 6.3% of patients. The results obtained during the biochemical analysis of blood serum indicate the presence of atherogenic dyslipidemia, an increase in the level of total protein, bilirubin, transaminases, gamma-glutamyl transpeptidase and a decrease in alkaline phosphatase in relation to the control group. Against the background of elevated glucose levels, an increase in basal insulin levels was observed (p=0.001). HOMA-IR insulin resistance was increased in patients (p=0.01). When analyzing the results of the study, the main prognostic criteria (body mass index and atherogenicity coefficient) in the diagnosis of non-alcoholic fatty liver disease in the stage of steatosis with high specificity (97.8%) and sensitivity (96.2%) were determined. In determining the risk of progression of non-alcoholic fatty liver disease into liver fibrosis, the model of prognostic criteria included insulin and triglycerides with a specificity of 93.8% and a sensitivity of 85.7%.

CONCLUSION

Among many variable factors, we have identified the main prognostic criteria that are highly likely to diagnose non-alcoholic fatty liver disease at an early stage and determine the risk of progression to liver fibrosis.

Evaluation of the effectiveness of differentiated therapy of non-alcoholic fatty liver disease

Aim.Study of the effectiveness of differentiated therapy of non-alcoholic fatty liver disease taking into account the clinical and pathogenetic features of its course. Materials and methods.168 patients with non-alcoholic fatty liver disease were examined, 108 of them were women and 60 men aged from 30 to 70 years. For treatment, depending on the characteristics of the course of the disease, 3 groups of patients were formed. The first group included patients (n=47) with liver steatosis with a high content of lipids in the blood and an increased atherogenic coefficient; they received therapy with ursodeoxycholic acid with atorvastatin. The second group consisted of patients (n=65) with liver steatosis with an increased level of glycemia, insulin and insulin resistance, they were prescribed therapy with ursodeoxycholic acid and metformin. Patients of the third group (n=56) with steatohepatitis with concomitant bacterial overgrowth received еssentiale forte H therapy with rioflora immuno. Clinical data, blood biochemical parameters, insulin and HOMA-IR levels, intestinal microbiota status, as well as regression of liver steatosis and steatohepatitis were evaluated in the dynamics of treatment. Results.In the dynamics of treatment, there was a decrease in the clinical manifestations of the disease in all observed groups of patients, an improvement in lipid metabolism and indicators of the functional state of the liver, a decrease in excessive bacterial growth. On the basis of ultrasound, elastography and fibrotest, the reverse development of liver steatosis was found in 20% and steatohepatitis in 66.6% of patients. Conclusion.The data obtained indicate the feasibility of differentiated treatment of patients with non-alcoholic fatty liver disease depending on thecharacteristics of its course and stage.
