[DETERMINING THE DEGREE OF LIVER DYSFUNCTION IN CHILDREN WITH POSITIONS OF THE INTERNATIONAL CLASSIFICATION OF FUNCTIONING, DISABILITY AND HEALTH (ICF)].

Methods: Based on a retrospective analysis of biochemical blood parameters which characterize the role of liver function in the metabolism of proteins, fats and carbohydrates (considered indicators of ALT, AST, De Ritis coefficient, bilirubin, albumin, fibrinogen, prothrombin, transferrin, ceruloplasmin, cholesterol, urea, ammonia, glucose, lactate) in 95 children without liver pathology, 15 children who died of liver failure, 295 patients with various liver diseases who were treated in the SCCH, a scale system was developed as a support tool to assess liver dysfunction.

Results: Each biochemical indicator was assessed on a five-point scale. The level of a biochemical indicator, which corresponded to the absence of disorders, was estimated as 4 points, corresponding to "insignificant disorders"--as 3 points, "moderate disorders"--as 2 points, "severe disorders"--as 1 point, "absolute disorders"--as 0 points. The total score is the estimate of the degree of liver dysfunction. According to the recommendations of the International Classification of Functioning, Limitations of vital activities and Health, the decrease of the number of points on 0-4% (54-56 points) corresponds to the absence of the liver dysfunction, on 5-24% (43-53 points)--insignificant disorders of liver function, on 25-49% (29-42 points)--moderate hepatic impairment, on 50-95% (3-28 points)--severe disturbances of liver function, on 96-100% (0-2 points)--absolute dysfunction of the liver.

Conclusions: A scoring system of assessing liver dysfunction can be applied at any stage of the examination and treatment of children of any age, as used in biochemical parameters do not depend on the age of the patient. It is an objective criterion for assessing the degree of liver dysfunction and can be used to assess the severity of the pathological process in the dynamics determining the prognosis of the disease and can be the criterion of the indications for liver transplantation, and also used during the of medico-social expert examination.
