Abstract:
【Objective】 To investigate the effect of two different oral calcium supplementation methods(method 1: bone health basic supplements in the interval plus routine calcium supplement; method 2: only routine calcium supplement on the day of donation)on platelet donors, to improve some biochemical indexes of the body caused by citrate anticoagulant. 【Methods】 A total of 252 long-term regular platelet donors in our station from January 2019 to December 2020 were selected and randomly divided into two groups: experimental group (n=126) were given 10% calcium gluconate oral solution 20 mL before platelet collection, orally. Oral caltrate D3 (containing 600 mg calcium carbonate and 125 international units of vitamin D3) was administered in the interval (20±2 days), 1 tablet per day. Oral alfacalcidol soft capsule (containing alfacalcidol 0.25 μg), 1 tablet per day; control group (n=126) were given routine administration of 10% calcium gluconate oral solution 20 mL before platelet collection. Serum PTH and serum concentrations of calcium, magnesium, phosphorus and 25 hydroxyvitamin D of the two groups were detected at 0 min after injection and 0 min after the end of the last circulation, respectively. Meanwhile, the occurrence of blood donation reactions was observed in the two groups. 【Results】 In the experimental group and control group, serum PTH concentration both increased significantly after donation, while serum calcium, inorganic phosphorus, magnesium and 25 hydroxyvitamin D decreased significantly(P<0.01). After donation, 4 donors in the experimental group and 8 in the control group showed citrate reaction, with the incidence of adverse reactions at 3.17%(4/126)and 6.34%(8/126), respectively. Before blood collection, serum calcium concentration in the experimental group was higher than that in the control group, while PTH concentration was lower than that in the control group (P<0.01), but no significant differences were noticed in serum magnesium, inorganic phosphorus and 25 hydroxyl vitamin D concentrations (P>0.05), and so was in the control group after blood collection. 【Conclusion】 Method 1 can further slow down the increase of serum PTH and the decrease of serum calcium, and can effectively reduce the citrate response of blood donors compared with method 2, which is of great significance to prevent osteoporosis in long-term regular blood donors.
