This retrospective prospective interventional study will examine vitamin D availability and its relationship with clinical disease, patient gender and age, and season. The mechanisms of impairment of phosphorus-calcium metabolism and bone tissue metabolism will be analyzed on the basis of biochemical parameters and instrumental research methods in children with dystrophic epidermolysis bullosa in order to develop personalized approaches for correcting vitamin D status and bone metabolism disorders in children with epidermolysis bullosa, followed by an assessment of their clinical efficacy.
This retrospective prospective study is aimed at studying the level of vitamin D supply and identifying markers of bone tissue remodeling in order to develop approaches to the prevention of osteopenia and osteoporosis in children with congenital epidermolysis bullosa.
