Mean age was 13.0 years (11.0; 15.5). All patients have active phase of the disease. Bone mineral density (BMD) of lumbar spine (DEXA) have been assessed in all children. Level of serum osteocalcin (OC) as a marker of osteosynthesis, C-terminal telopeptides (CTT) as a marker of osteoresorbtion, parathyroid hormone (PTH), serum calcium, phosphorus, alkaline phosphatase and 25(OH) vitamin D was measured to evaluate bone metabolism. Molecular-genetic tests: analysis of TaqI (rs731236) polymorphism of vitamin D receptor gene (VDR) was perfomed by polymerase chain reaction with following restriction analysis. Association between molecular markers of VDR gene and bone metabolism and mineralization disturbances have been found. TT genotype of VDR gene was associated with tendency to decrease of linear growth velocity, low linear growth, decrease in osteosynthesis and increase of osteoresorbtion in this group of children. TT-genotype of TaqI-polymorphism of VDR gene can be assessed as a risk factor of bone metabolism disturbances in children with both Crohn’s disease and ulcerative colitis. C allele seems to have protective role in this group.</p></abstract><trans-abstract xml:lang="ru"><p>В данном исследовании проводилась оценка минерализации скелета и костного метаболизма у детей с воспалительными заболеваниями кишечника (ВЗК) в зависимости от TaqI-полиморфизма гена рецептора витамина D (VDR). В исследование были включены 83 ребенка (38 девочек и 45 мальчиков), страдающих ВЗК (болезнь Крона - 60, язвенный колит - 23). Возраст детей, включенных в исследование, составил 13,0 (11,0; 15,5) года. Исследование минерализации скелета осуществлялось методом двухэнергетической рентгеновской абсорбциометрии L1-L4. Состояние костного обмена оценивалось по уровню основных метаболических маркеров: остеокальцина как маркера остеосинтеза, продуктов деградации коллагена I типа - С-концевых телопептидов как маркера остеорезорбции, паратгормона, общего и ионизированного кальция, фосфора, общей щелочной фосфатазы, 25ОНD3. Молекулярно-генетические исследования: анализ TaqI (rs731236) полиморфизма гена VDR осуществлялся методом полимеразной цепной реакции с последующим рестрикционным анализом. Выявлена ассоциация молекулярных маркеров гена VDR с нарушением костной минерализации и метаболизма. У детей с ВЗК ТТ-генотип гена VDR ассоциирован с тенденцией к задержке скорости линейного роста, низким линейным ростом, нарушением костного метаболизма в виде угнетения процессов остеосинтеза и активации костной резорбции. ТТ-генотип TaqI полиморфизма гена VDR в этой группе пациентов может рассматриваться как фактор риска развития нарушений костного метаболизма, а аллель С - как протективный.</p></trans-abstract><kwd-group xml:lang="en"><kwd>inflammatory bowel disease (IBD)</kwd><kwd>bone mineral density</kwd><kwd>Crohn’s disease</kwd><kwd>ulcerative colitis</kwd><kwd>gene of vitamin D receptor (VDR)</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>воспалительные заболевания кишечника (ВЗК)</kwd><kwd>минеральная плотность костной ткани</kwd><kwd>болезнь Крона</kwd><kwd>язвенный колит</kwd><kwd>ген рецептора витамина D (VDR)</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
