Bone density and bone metabolism in plasmapheresis donors
Objective To investigate the level of serum bone metabolism and biochemical markers and bone densi-ty of plasmapheresis donors,and to provide scientific basis for ensuring the health and safety of plasmapheresis donors in China.Methods A total of 437 plasmapheresis donors from Linwu plasmapheresis station in Hunan Province from July 1 to September 30,2022 were recruited to determine the levels of total serum calcium,albumin,serum 25-hy-droxyvitamin D(25OHD),serum type Ⅰ procollagen N-terminal propeptide(P1NP),and collagen type 1 crosslinked carboxy l-terminal peptide(β-CTX).Dual-energy X-ray method was used to measure the bone density of the anteroposte-rior lumbar spine(L1-L4)and bilateral femoral neck bone density of plasmapheresis donors.Plasmapheresis donors were grouped according to the type of plasma donation(first-time and repeat plasmapheresis donors)and the total num-ber of plasma donations to assess the differences in bone density and serum bone metabolism biochemical markers be-tween groups.The dose-response relationship between the total number of plasmapheresis donations and biochemical in-dexes was analyzed by limiting cubic spline,and the influencing factors of different indexes were explored by multiple linear regression.Results A total of 437 plasmapheresis donors were included in this study,including 187 first-time plasmapheresis donors and 250 repeat plasmapheresis donors.There were no significant differences in bone density and prevalence of osteoporosis between first-time donors and repeat donors(P＞0.05).There was also no significant differ-ence in bone density levels between groups of total number of plasmapheresis donations.The levels of albumin and 25OHD decreased with the increase of the total number of plasma donations,while the serum P1NP level was positively correlated with the total number of plasma donations.The results of the restriction cubic spline showed that the total num-ber of plasmapheresis donations had a nonlinear dose-response relationship with 25OH and P1NP(P＜0.05).The results of multiple linear regression showed that the frequency of plasmapheresis donation was the influencing factor of 25OHD,and the total number of plasmapheresis donation was the influencing factor of P1NP.Conclusion Plasmapher-esis donation does not affect the bone health of donors and increase the risk of osteoporosis due to the use of long-term anticoagulants,but it will increase the osteogenic activity of plasmapheresis donors.It is recommended that middle-aged and elderly plasmapheresis donors supplement vitamin D appropriately.
