    Abstract:
    Hyperphosphatemia is a common finding in patients with chronic kidney disease (CKD) undergoing hemodialysis or receiving conservative treatment. Recent papers have reported a link between hyperphosphatemia, soft tissue calcifications, and cardiovascular events responsible for high morbidity and mortality in these patients. Our group identified in salivary phosphate secretion a method to study the phosphate balance in CKD. Moreover, we found that CKD patients on hemodialysis usually drink beverages with a high phosphate content that may increase their serum phosphorus levels. Hyperphosphatemia is currently treated with diet, phosphate-binding drugs, and drugs acting on bone metabolism. Despite such treatment, only half of the patients with end-stage renal disease fall within the K/DOQI guidelines range for serum phosphorus levels. This paper reports positive results obtained with the use of the polymer chitosan as a phosphatebinding chewing gum in CKD patients undergoing periodic hemodialysis.
