A pilot study was conducted that included 52 children (35 girls and 17 boys) aged 5 to 17 years (11.88 ± 0.48 years), among them 29 children with systemic connective tissue disorders (SCTD) and 23 children with juvenile idiopathic arthritis (JIA). All patients underwent complex clinical-laboratory and instrumental examination in order to confirm the diagnosis and assess the patients’ health. Vitamin D status was assessed by 25(ОН)D serum levels using the method of chemiluminescence immunoassay. Results. Sufficient levels of 25(ОН)D (>30 ng/l) were found only in 5 (9.5%) children, vitamin D insufficiency (25(ОН)D 21–30 ng/l) was observed in 6 (11.5%) children, deficiency (25(ОН) <20 ng/l) in 41 (79.0%) children, among them in 7 (13.4%) it was severe (25(OH)D <10 ng/l), in spite of a long-term intake of low-doses of cholecalciferol (100–400 U/day) by 40 (76.9%) patients. Average levels of 25(ОН)D in patients with SCTD were significantly higher than in patients with JIA (20.86 ± 2.15 ng/l vs. 14.98 ± 0.91 ng/l, p = 0.0151), deficiency was more rarely found in these patients (69.0% vs. 91.3%), which was to a certain degree conditioned by more intensive vitamin D therapy. Conclusion. Insufficiency/deficiency of vitamin D is noted in an overwhelming majority of children with RD. Standard therapy with low doses of cholecalciferon offered to patients with RD is not sufficient for obtaining optimal 25(ОН)D levels and needs correction.
