Abstract:
【Objective】 To investigate the effect of multiple apheresis platelet donation on platelet indexes and aggregation function in platelet donors, and to analyze the relationship between platelet indexes and their relationship with platelet aggregation rate. 【Methods】 A total of 83 platelet donors were randomly selected from Foshan Central Blood Station from September 2021 to October 2022, and were divided into control group (n= 9, first-time platelet donors or donors with the time interval from the last platelet donation >1 year) and study group (n= 74, repeat platelet donors or donors with the time interval from the last platelet donation ≤ 1 year) according to the times of blood donation. The study group was divided into 4 subgroups: 2-5 times group, 6-10 times group, 11-15 times group and 16 times group. The platelet count(Plt), platelet distribution width (PDW), mean platelet volume (MPV), large platelet ratio (P-LCR), and maximum platelet aggregation rate (MAR) before donation in each group were detected and analyzed. 【Results】 There were no significant differences in Plt, MPV, PDW, P-LCR and MAR between the subgroups and the control group (P>0.05), and there were no significant differences in Plt, MPV, PDW, P-LCR and MAR between each subgroup (P>0.05) .There was a positive correlation between Plt and MAR in blood donors (P<0.05), and the correlation coefficient was 0.445. MPV, PDW and P-LCR were negatively correlated with MAR (P<0.05), and the correlation coefficients were -0.282, -0.233 and -0.217, respectively. Plt was negatively correlated with MPV, PDW and P-LCR (P < 0. 05), and the correlation coefficients were -0.399, -0.307 and -0.339, respectively. MPV, PDW and P-LCR are positively correlated with each other. The correlation coefficient between MPV and PDW was 0.792, that between MPV and P-LCR was 0.863, and tthat between PDW and P-LCR was 0.817. 【Conclusion】 There was no significant effect of multiple platelet donations on Plt, PDW, MPV, P-LCR and MAR in blood donors. Plt has the most significant impact on MAR among platelet indexes of platelet donors.
