Abstract:
Objective:To investigate the effect of suspended leukocyte poor red blood cell transfusion on hemeoxygenase-1 (HO-1) expression and T lymphocyte subsets in peripheral blood of patients with myelodysplastic syndrome.Methods:50 cases of MDS patients treated in Shandong Blood Center from January 2016 to December 2019 were selected as the research object. According to the different infusion of blood components, they were randomly divided into the observation group and the control group, with 25 cases in each group.The patients in the observation group were treated with s suspended leukocyte poor red blood cell transfusion, and the patients in the control group were treated with washing red blood cell infusion.The level of HO-1, interleukin-6 (IL-6) and TNF-α and the T cell subset such as CD 3+, CD 4+, CD 8+ and CD 4+/CD 8+ in the serum before and after transfusion were tested by enzyme linked immunosorbent assay and flow cytometry, respectively. Results:There was no statistically significantdifference in the level of HO-1, IL-6 and TNF-α in the serum of the two groups before transfusion ( P>0.05); After transfusion, TNF-α in the serum of the observation group significantly decreased, compared with that in control group: (152.10 ± 21.89) ng/L vs. (201.14 ± 28.90) ng/L, (1.34 ± 0.45) ng/L vs. (2.89 ± 1.01) ng/L. However, the HO-1 significantly increased: (78.91 ± 15.74) μg/L vs. (58.99 ± 13.33) μg/L, andthe difference was statistically significant ( P<0.05). There was nostatistically significantdifference in the immunologic functions of the two groups before transfusion ( P>0.05); After transfusion, CD 4+/CD 8+of the observation group both significantly increased, compared with that inthe control group: (49.11 ± 19.13)% vs. (47.13 ± 12.84)%, (25.23 ± 10.80)% vs. (21.09 ± 12.28)%, (24.74 ± 10.84)% vs. (21.88 ± 11.18)%, 1.02 ± 0.25 vs. 0.96 ± 0.20, and the difference was statistically significant ( P<0.05). Conclusions:The expression level of HO-1 in peripheral blood and immune function of patients with myelodysplastic syndrome can be improved by suspended leukocyte poor red blood cell transfusion.
