Objective. To analyze cardiovascular disorders, lipid metabolism disorders, compliance level and quality of life of liver transplant recipients and to develop individualized approach to prediction of complications development with the use of artificial neural networks. Materials and methods. In the retrospective part of the study a database of primary documents of 135 patients (81 male, 54 female) who underwent orthotopic liver transplantation (OLT) in State Budgetary Healthcare Institution “Research institute - Prof. S.V. Ochapovskii Regional Clinical Hospital №1” in Krasnodar was developed. The present article analyses recipients cardiovascular status before and 4 years after liver transplantation as well as lipid and carbohydrate metabolism disorders at 6, 12, 24, 36, and 48 months with the use of Statistica 10.0 (Tibco, USA) software. In the prospective part questionnaire survey of the patients about compliance and quality of life was conducted. The designed recipients database was used for development of neural networks models in the program unit in Microsoft Visual C# 2015 software development environment for prognosis of complications development in liver transplant recipients according to combined endpoint - transplant hepatitis, thrombosis, tumors and episodes of transplant rejection. Results. Total cholesterol level was 3.6±1.6 mmol/L before transplantation, after 6 months, 12 months, 2, 3, and 4 years it increased by 16.7, 19.4, 27.8, 38.9 и 38.9%, respectively. Triglycerides level dynamics compared with baseline level before transplantation increased by 29.3, 41.7, 36.7, 52.2, 43.0% after 6 months, 1 year, 2 years, 3 years, and 4 years, respectively. Low density lipoprotein level before operation was 2.3±1.4 mmol/L and in 2 years increased by 8.7%, in 3 and 4 years by 21.7 и 26.1%, respectively. Before transplantation arterial hypertension was diagnosed in 21.5% of patients, the number increased to 29.6% during the observation period. Diabetes mellitus was diagnosed in 14.4% of patients before transplantation and in 22.7% of patients 4 years after it. Four years after liver transplantation the amount of patients with ischemic heart disease and chronic heart failure increased by 27.4 and 20.7%. Both in female and male liver transplant recipients low compliance to treatment was observed according to Morisky-Green questionnaire test. Most differences between recipients and healthy people were observed in “physical functioning” score - by 31.3%, “role functioning defined by physical functioning” - by 60.8%, “general state of health” - by 33.4%, “role functioning defined by emotional state” - by 52.9%. Characteristics of cardiovascular status of liver recipients, compliance and quality of life were included in artificial neural networks in program “Complication prognosis in liver recipients” with total predictive capability of the network accounted for 98.49%. Conclusion. In liver recipients frequency of cardiovascular disorders, diabetes mellitus and lipid metabolism disorders increased in comparison with pre-transplantation period. Study of compliance, quality of life and formed database of clinical, laboratory, and instrumental data on patients before transplantation and in 5 periods of time after it along with the use of neural networks allowed creating a program “Complication prognosis in liver recipients”, certificate of registration of computer program №2019614005.
