Особенности течения ЮИА могут быть генетически детерминированы.</p><p>Цель исследования – дать оценку активности ЮИА у детей с ApaI и BsmI полиморфными генотипами гена рецептора витамина D (VDR).</p><sec><title>Материал и методы</title><p>Материал и методы. В исследование включен 71 ребенок, страдающий ЮИА. На момент включения в исследование все пациенты находились в активном состоянии болезни. Оценка активности ЮИА осуществлялось при помощи наиболее часто используемых клинических и лабораторных показателей, в том числе суставного индекса Ричи (CИР), индексов JADAS10, JADAS27, JADAS71, CDAI, DAS и DAS28.

The investigation enrolled 71 patients with JIA. When included in the investigation, all the patients were in an active state of disease.
