Objective. To analyze the calcium-phosphorus metabolism in patients with diabetes mellitus (DM) type 1 depending on the functional state of the kidneys. Materials and Methods. The study involved 235 patients with type 1 diabetic (males). One hundred and thirty-four patients entered the group without diabetic nephropathy (DN) and 101 patients entered the group with DN. To study the phosphorous-calcium metabolism in patients with type 1 diabetes there were studied the following parameters in blood plasma: the level of intact parathyroid hormone (PTH), total calcium (Ca), ionized calcium (Ca2+), serum phosphorus (P), as well as calculated CaxP product. Results.  In patients with type 1 diabetes in the progression of DN the increase of P was observed from stage 4 CKD and reduction of Ca ? from CKD stage 5. The increase of the level of PTH was observed from the stage of CKD 3, although isolated cases of secondary hyperparathyroidism were registered in patients with stage CKD 2. At the same time in a large group of the patients with type 1 diabetes there was observed level of PTH below the target values of the stages CKD 3, 4, 5. The deterioration of glycemic control in patients with type 1 diabetes is associated with decreased level of PTH. In patients with type 1 diabetes without DN and with DN there was observed inverse relationship between the level of glycated hemoglobin (HbA. 1c). Conclusion. In patients with type 1 diabetes the progression of DN leads to various disorders of phosphorus-calcium metabolism: reduction of Ca, higher level of P, alter the function of the parathyroid glands (secondary hyperparathyroidism and reduction of PTH below the target value). Deterioration of glycemic control in patients with type 1 diabetes is associated with a reduction of PTH.

Objective. To identify factors associated with the development of secondary hyperparathyroidism in patients with type 1 diabetes mellitus with diabetic nephropathy.Materials and methods. One hundred and one patients (males) with type 1 diabetes mellitus with diabetic nephropathy who were treated in endocrinology department of the Regional clinical hospital were examined. For the study of calcium and phosphorus metabolism in patients with type 1 diabetes mellitus, we investigated the following parameters in the blood plasma: level of intact parathyroid hormone, total calcium, ionized calcium, serum phosphorus.Results. The study showed that in patients with type 1 diabetes mellitus with diabetic nephropathy factors associated with the development of secondary hyperparathyroidism are: the age above 30 years old, the duration of diabetes for more than 15 years, reduction of glomerular filtration rate of less than70 ml/min/1,73 m2 and the development of anemia. Factor associated with the reduction of secondaryhyperparathyroidism is the level of glycated hemoglobin of more than 8%.Conclusion. Thus, patients with type 1 diabetes mellitus with diabetic nephropathy represent a group of increased risk for development of violations of calcium and phosphorus metabolism. Analysis of the factors associated with the occurrence of secondary hyperparathyroidism in diabetic nephropathy allowed to identify a group of high risk of development of this pathology.
