Objective: to study features of vitamin D status of children with chronic hepatitis C depending upon age, gender, seasonality, place of residence and activity of hepatitis.

Materials and methods. In total 28 children with chronic hepatitis C were examined during the period of 2015–2018. A complex of laboratory tests in accordance with the protocol was conducted. To verify the vitamin D status, the 25(OH)D3 serum concentration was determined. The peculiarities of vitamin D status in children depending upon gender, age, seasonality, place of residence were studied, as well as the activity of hepatitis.

Results. In the majority of children that made up 60.7% (n=17) a vitamin D level decrease was detected, in 28.6% (n=8) of which insufficiency was diagnosed and deficiency – in 32.1% (n=9). The optimum vitamin D level was found in 39.3% (n=11) of children. The average vitamin D level in children with chronic hepatitis C constituted 23.05 [15.44–38.05] ng/mL and showed its insufficiency. It was found that the optimum vitamin D level was significantly more frequently observed in children with inactive hepatitis as compared to the group of children with ALT-3N (χ2=3.97, р=0.04). A significant negative correlation was found between the activity of hepatitis and vitamin D concentration in the blood serum of children with chronic hepatitis С (R<0.4; p=0.03). No influence of gender, age, place of residence and seasonality on the vitamin D status in the examined children with chronic hepatitis С (p>0.05) revealed.

Conclusions. In the majority (60.7%) of children with chronic hepatitis C, a reduced 25(OH)D in serum was revealed. It is shown that vitamin D status in children with this disease had an inverse correlation with the biochemical activity of hepatitis (according to transaminases level). There was no statistically significant difference between the vitamin D status of children with chronic hepatitis C, depending upon gender, age, seasonality and place of residence.

Key words: children, chronic hepatitis C, vitamin D, hepatitis activity.
