Predicting the course of uveitis against the background of juvenile idiophatic arthritis when using topical therapy regimens. The results of mathematical modeling

BACKGROUND: Juvenile idiopathic arthritis is the most common rheumatic disease in children, and uveitis is its most destructive extra-articular manifestation. Despite the existence of Federal clinical guidelines for the management of these patients, their treatment is largely based on the experience of doctors and varies greatly even within the same country. AIM: The aim of the study is to find factors for predicting the course of uveitis and optimizing therapy. MATERIALS AND METHODS: The case histories of 150 children aged 1.5 to 17 years with active uveitis in the structure of juvenile arthritis were analyzed using multifactorial modeling (construction of classification trees). RESULTS: The fact of a significant influence of the time elapsed from the onset of rheumatic disease and uveitis until the start of therapy by genetically engineered medications (tumor necrosis factor alpha inhibitors) in treatment programs has been established. CONCLUSIONS: Thus, the inclusion of this factor into the group of controlling ones makes it possible to achieve inactive uveitis status after 1, 3, and 6 months in a higher percentage of cases. However, the obtained data still require additional clinical confirmation.
