ABSTRACT
OBJECTIVE@#To explore the feasibility of RhCcEe blood group antigen mixed visual field identification in patients with regular blood transfusion, to follow up and evaluate the efficacy of matched transfusion and its clinical significance.@*METHODS@#RhCcEe genotyping for 142 patients with regular transfusion in our hospital was carried out by PCR-SSP method. According to the results of genotyping, 48 patients voluntarily selected the continuous transfusion of RhCcEe matched red blood cells, 46 patients received random blood transfusion (RhCcEe mismatched transfusion), 42 patients received partial RhCcEe matched transfusion (unable to provide fully matched RhCcEe donors each time), and 6 patients' blood transfusion data were lost. After 3-6 months of the RhCcEe matched transfusion, all patients were tested by RhCcEe microcolumn gel card and compared with the results before RhCcEe matched transfusion. The positive rates of alloantibodies, DAT and the percentage of red blood cell invalid transfusion were followed up and evaluated for the above-mentsioned 3 types of regular transfusion patients in the past 5 years.@*RESULTS@#Out of the 48 patients who underwent conti-nuous RhCcEe matched transfusion, only 1 case showed stratification, the remaining 47 cases had clear gel card results without stratification, suggesting that PCR-SSP genotyping was feasible. In addition, another 42 patients who could not receive RhCcEe matched transfusion each time and 46 patients with random blood transfusion were found to have a mixed vision phenomenon again. but the results was still difficult to confirm the results. For the transfusion results in the past 5 years, follow-up analysis showed that there were 1 case alloantibody (anti-Jka) (1/48) , 1 case of DAT positive (1/48) and 2 cases of invalid transfusion (2/48) in the RhCcEe matched transfusion group; 7 cases of alloantibodies (3 anti-E, 1 anti-E+anti-c, 1 anti-C, 1 anti-M, 1 anti-Fya) (7/46), 6 case of DAT positive (6/46) and 9 case of invalid transfusion (9/46) in the random transfusion group; 6 cases of alloantibodies (1 anti-E, 1 anti-E+autoantibody, 1 anti-C, 1 anti-c, 1 anti-M and 1 other antibody) (6/42) and 7 case of DAT positive (7/42) and 8 case of invalid transfusion (8/42) in the partial RhCcEe matched transfusion group. The statistical analysis showed that the positive rate of alloantibodies and the invalid infusion rate of RBC in each group were significant differences between RhCcEe matched transfusion group and the random transfusion group as well as betwen Rhce fe matched transfusion group and the partial matched transfusion group(P<0.05), but there was no statistical difference between the random transfusion group and the partial matched transfusion group(P>0.05).@*CONCLUSION@#PCR-SSP genotyping technique can be used to detect RhCcEe mixed vision in patients with regular blood transfusion. Continuous RhCcEe matched transfusion can effectively prevent the occurrence of alloimmunization, and improve the clinical transfusion efficacy and safety of the patients with regular blood transfusion, which has very important clinical significance.
