Abstract:Objective: To observe the efficacy of active vitamin D combined with cinacalcet in the treatment of secondary hyperparathyroidism (SHPT) in dialysis patients with chronic renal failure and its effects on levels of serum transforming growth factor-β1 (TGF-β1) and serum transferrin receptor (sTfR). Methods: 90 patients with chronic renal failure who underwent MHD causing moderate-to-severe SHPT were randomly divided into control group and observation group, with 45 cases in each group. Control group was treated with calcitriol, and observation group was given calcitriol combined with cinacalcet. The clinical efficacy and changes of parathyroid size, blood calcium, blood phosphorus, intact parathyroid hormone (iPTH), renal function indexes, TGF-β1 and sTfR before and after treatment were compared between the two groups, and adverse reactions were observed in the two groups. Results: The total effective rate was 93.33% in observation group and 75.56% in control group (P<0.05). After treatment, the decreases of length, width and thickness of parathyroid glands in observation group were more significant than those in control group (P<0.05), and the increase of blood calcium was more significant than that in control group (P<0.05), and the decreases of blood phosphorus and iPTH were more significant than those in control group (P<0.05). There were no significant changes in renal function indexes [serum creatinine, urea nitrogen, urea clearance index] before and after treatment between the two groups (P>0.05). After treatment, the serum levels of TGF-β1 and sTfR were significantly decreased in the two groups (P<0.05), and the decreases in observation group were more significant than those in control group (P<0.05). There was no significant difference in the incidence rate of adverse reactions between the two groups (P>0.05). Conclusion: Calcitriol combined with cinacalcet has significant efficacy in the treatment of SHPT in MHD patients with chronic renal failure, and it can effectively improve the high iPTH status and calcium and phosphorus imbalance, reduce the expressions of TGF-β1 and sTfR, and will not adversely affect residual renal function, with good safety.
