ABSTRACT
Objective To observe the influence of calcitriol combined with prolonged hemodialysis on parathyroid hormone (PTH),phosphorus and calcium in maintenance hemodialysis patients with refractory secondary hyperparathyroidism.Methods Twenty-two maintenance hemodialysis patients received prolonged hemodialysis (3 times per week and 6 hours each session) and therapy with calcitriol (3 times per week and 1 μ g each time) for 3 months.The levels of serum PTH,calcium and phosphorus of these patients were recorded before and after treatment.Results Compared with that before treatment,the level of serum PTH and phosphorus was decreased significantly[(484.21 ± 230.18) nmol/L vs.(750.53 ± 327.41) nmol/L,(1.49 ±0.27) mmol/L vs.(2.37 ±0.76) mmol/L],but calcium was increased after treatment [(2.35 ±0.32) mmol/L vs.(1.81 ±0.53) mmol/L],and there was significant difference (P ＜0.05).Conclusions The treatment of calcitriol combined with prolonged hemodialysis not only effectively clear phosphorus and PTH but also increase calcium in maintenance hemodialysis patients.The therapeutic schedule is good to maintenance hemodialysis patients with refractory secondary hyperparathyroidism.
