[CONDITION OF HEPATOBILIARY SYSTEM IN JUVENILE RHEUMATOID ARTHRITIS].

The Article is dedicated to the results of the clinical-biochemical, biophysical and pathomorphological study of liver in the patients with juvenile rheumatoid arthritis. Liver injury in 64.8 % of patients with JRA was found, showing signs of mesenchymal inflammation, hypoalbuminemia, hyperbilirubinemia, hyperenzymemia. The importance of elastography in the early diagnosis of liver fibrosis in patients with JRA was determined. Results of morphological studies of patients who died of liver JRA treated with methotrexate showed that in contrast to patients not receiving methotrexate noted the development of more severe disorganized, dystrophic and immunopathological processes with transition to the sclerotic and fibromatous changes.
