 The objective of the research is a comparative study of hormones-regulators of bone metabolism and biochemical markers of mineral metabolism (calcium, phosphorus, magnesium) in female patients with differentiated and undifferentiated forms of connective tissue dysplasia (CTD). We evaluated the bone metabolism and the processes of bone tissue remodeling as well. Assessment of blood levels of thyroid-stimulating hormone, triiodothyronine, parathyroid hormone, prolactin, adrenocorticotropic hormone, cortisol, growth hormone and electrolytes (calcium, phosphorus, magnesium), bone resorption (osteocalcin and alkaline phosphatase) and bone formation (deoxypyridinoline, urine calcium) markers was performed in 120 patients (105 with undifferentiated form of CTD and 15 with Marfan syndrome). In patients with Marfan syndrome, the decrease of magnesium content and increase of phosphorus level under normal calcium concentration in blood serum was found. Under hereditary dysplasia of connective tissue, the hormonal profile is characterized by fluctuations in ACTH and parathyroid hormone, mainly in female patients with Marfan syndrome.

Key  words: biochemical markers, bone metabolism, connective tissue dysplasia
