Systemic juvenile idiopathic arthritis in the republic of Bashkortostan

Methods We observed 56 patients, who fell ill in the age of 16, and were diagnosed systemic JIA. The diagnosis was defined by the ILAR criteria (Edmonton, 2001) as arthritis and a documented quotidian fever of at least two week duration, plus one or more of the following: typical rash, generalized lymphadenopathy, enlargement of liver or spleen, serositis. According to the course of disease the patients were divided into three subgroups: 1. Monocyclic disease course, patients had only one attack. 2. Polycyclic disease course was characterized by recurrent episodes of remission without medication. 3. Chronic persistent course, patients had extended poly-arthritis with or without systemic features.
