Objective. To study the level of FGF23 before and after thesecondary hyperparathyroidism surgical treatment and in the comparison groups in patients receiving hemodialysis divided by the level of parathyroid hormone and in healthy people.
Methods. The level of FGF23; pg/ml in the blood was simultaneouslystudied before and after surgical treatment for secondary hyperparathyroidism in patients undergoing renal replacement therapy. In the comparison groups, the level of FGF23 in the blood was studied in patients receiving dialysis for the terminal stage of chronic kidney disease (CKD). The groups were divided according to the level of intact parathyroid hormone (PTH) in the blood: with hypoparathyroidism (PTH less than 130 pg/ml), with an acceptable level of PTH (130-600 pg/ml), and hyperparathyroidism (PTH more than 600 pg/ml). The level of FGF23 in healthy individuals was also studied. A total of 77 people were examined (33 females and 44 males). To assess the mineral-bone disorders, the standard laboratory examination was performed: a biochemical blood test with electrolytes (albumen, total calcium with albumin correction, phosphorus), PTH in blood.
Results. Data have been obtained that the level of FGF23 in the group of healthy individuals is statistically lower than in the other groups (pU = 0.001). Between groups of people with terminal stage of CKD, the difference in FGF23 is not statistically significant (pU > 0.05).
Conclusions. All patients receiving dialysis, regardless of the severity of secondary hyperparathyroidism before and after surgical treatment, have an increased level of FGF23 in comparison with healthy people. Statistically significant differences in level of FGF23 depending on the presence or absence of secondary hyperparathyroidism and the result of surgical treatment of SHPT were not detected. According to the data obtained, further research is needed to identify the role of FGF23 in the pathogenesis of secondary hyperparathyroidism.
