OBJECTIVE： To investigate the effects of sevelamer carbonate combined with routine treatment on serum inflammatory factors， heme oxygenase-1 （HO-1） and intact parathyroid hormone （iPTH） levels of chronic renal failure （CRF） patients with hyperphosphatemia. METHODS： Totally 60 chronic renal failure patients with hyperphosphatemia in department of renal internal medicine， Tangshan Workers’ Hospital during Jan. 2014 to Jan. 2015 were divided into control group and observation group according to random number table， with 30 cases in each group. Control group received routine treatment as reducing blood glucose， lowering blood lipid， lowering blood pressure， reducing phosphorus， protecting kidney. Observation group was additionally given sevelamer carbonate （dose was 0.8 g， 3 times a day， during meal） on the basis of control group， for 4 weeks. The levels of IL-6， CRP， HO-1， iPTH， Ca and P were compared between 2 groups. The occurrence of ADR was compared between 2 groups. RESULTS： Two cases were withdrewn from the study in each group， finally 28 cases were included in the study in each group. Before treatment， there was no statistical significance in each index between 2 groups （P＞0.05）. Compared with before treatment， the serum levels of IL-6， CRP， iPTH and P in 2 groups were decreased significantly after treatment （P＜0.05）， while serum level of Ca was increased significantly （P＜0.05）； the improvement of above indexes in observation group were more dovious than control group （P＜0.05）. There was no statistical significance in the incidence of ADR between 2 groups（P＞0.05）. CONCLUSIONS： Sevelamer carbonate combined with routine treatment can effectively reduce the serum levels of IL-6， CRP， HO-1 and iPTH and regulate Ca and P metabolism of CRF patients with hyperphosphatemia with good safety.
