Аннотация
INTRODUCTION: Hyperphosphatemia in advanced CKD often accompanies high PTH and FGF23 levels, impaired bone mineralization, ectopic calcifications, and increased cardiovascular risks. Novel treatments are now available to lower serum phosphorus effectively. However, safety, tolerability, and patient adherence must be evaluated to determine the best therapeutic option for hyperphosphatemia.
AREAS COVERED: This review examines available treatment strategies for hyperphosphatemia in CKD patients and new emerging treatments, emphasizing the latest inhibitors of active phosphate absorption.
EXPERT OPINION: Despite the numerous compounds available, managing hyperphosphatemia in CKD remains challenging. While many phosphate binders exist, they often have limitations and side effects. Aluminum carries significant toxicity risks. Calcium-based binders are effective but can cause hypercalcemia and vascular calcification. Lanthanum is absorbed in the gut, but its long-term tissue deposition appears clinically irrelevant. Sevelamer reduces vascular calcification but has inconclusive data and gastrointestinal side effects. Iron-based binders are effective but may cause gastrointestinal discomfort and lack long-term outcome data. New inhibitors of intestinal phosphate absorption show promise with low pill burden but need more clinical validation. Although these newer compounds might eventually improve phosphate management in CKD patients, enhancing adherence and reducing pill burden, future studies are required to elucidate the best treatment for hyperphosphatemia.
