Перенести в английский вариант BACKGROUND. Hyperphosphatemia in CKD is spread widely, represents as independent factor of mortality at all stages of CKD, after transplantation, reduces the effectiveness of nephroprotection, leads to vascular calcification, stimulates hyperparathyroidism. Achieving the phosphatemia target is a difficult task and is based on a combination of a hypophosphate diet, effective dialysis, the antihyperparathyroidic measures and the phosphate-binders (PBs). THE AIM. The aim is to evaluate the effectiveness of sevelamertherapy in real clinical practice as part of a hypophosphatemic strategy with clarification of the conditions and measures under which it is optimal. PATIENTS AND METHODS. In an eight-month study in a region where there are no restrictions on access to calcium-free PBs, 127 patients were included in the study after the "washing period ": the of sevelamer doses were titrated until phosphatemia reaches below 1.58 mmol/l in parallel with individual measures of four-component hypophosphatemic strategy. RESULTS. From the starting dose of 3-6 tablets/day, 38 patients experienced either dose increase (+ 1016 ± 760 mg) or in 28 patients– decrease (- 1427 ± 1059 mg). By the third month of therapy, the proportion of patients with phosphatemia < 1.58 mmol/l reached 70 %, < 1.78 mmol/l – 90 %. The decrease magnitude depended on the initial phosphatemia, the level of PTH (maximum in the range of 150-600 pg/ml), occurs more slowly in men. During therapy, there was a decrease in the need for antihyperparathyroid therapy in the absence of dynamics in the parathyroid hormone level. In multiple regression analysis models, the independent factors associated with phosphatemia during treatment were sevelamer dose, dialysis dose, baseline phosphate and parathyroid hormone levels; the magnitude of phosphatemia reduction was independently associated with sevelamer dose, dialysis dose, baseline parathyroid hormone level, and assessment of treatment compliance. CONCLUSION. Sevelamer in a moderate well–tolerated doses as part of an individualized hyperphosphatemia correction strategy is able to achieve target phosphatemia (< 1.58 mmol/L) in 70 % of cases, and relatively safe level (< 1.78 mmol/L) – in 90 %.
