Abstract:
OBJECTIVE:To explore the serological characteristics of patients with autoimmune hemolytic anemia（AIHA） and analyze its clinical efficacy and safety of incompatible red blood cell transfusion.
METHODS:Sixty AIHA patients admitted in our hospital from January 2014 to January 2018 were selected. The blood type serological characteristics of 60 patients were analyzed retrospectively. According to the type of autoantibody and the composition of different red blood cells, the efficacy and safety of erythrocyte infusions were evaluated respectively.
RESULTS:The screen results of irregular antibody in 60 AIHA patients were positive, and the direct anti-human globulin test also was positive, including 8 cases of cold autoantibodies (13.33%), 49 cases of IgG warm autoantibodies (81.67%), and 3 cases of warm cold double autoantibodies (5%). The irregular anti-body identification test confirmed the existence of homoantiboby in 17 cases (28.33%). Out of 60 cases 34 received incompatible red blood cell (RBC) infusion for 108 time including ABO homotype non washing RBC (81 tirnes) and O type washing RBC (27 times). The infusion results showed that the total [JP2]effective rate was 57.41(62/108), total partial effective rate was 14.81% (16/108) and total ineffective rate was 27.78% (30/108).The infusion of ABO homotype non-washing RBC for 81 time showed that the effective rate was 58.02%[JP] (47/81) , partial effective rate was 12.35 (10/81) and ineffective rate was 29.67% (24/81); the infusion of O type washing RBC for 27 times showed that the effective rate was 55.56% (15/27), partial effective rate was 22.22% (6/27) and ineffective rate was 22.22% (6/27), there was no significant difference in effective rate between 2 kinds of infusion (P>0.05). The comparison of different antibody type infusion showed that in the infusion of IgM cold autoantiboay for 12 times, the effective rate was 41.67% (5/12), partial effective rate was 33.33% (4/12) and ineffective rate was 25% (3/12); in the infusion of IgG warm antoantibody for 93 times. The effective rate was 58.06% (54/93),partial effective rate was 12.90% (12/93) and ineffective rale was 29.04% (27/93), there was also no significant difference in effective rate between 2 kinds of infusion(P>0.05). However, in infusion of cold/warm double autoantibody for 3 times, the effective rate was 100% (3/3), moreover, the hemotytic reaction of infusion was not observed during the treatment .
CONCLUSION:The infusion of ABO homotype non-washing RBC and O type washing RBC both possess the high safely and efficacy for treatment of patients with AIHA, but the use of ABO homotype non-washing RBC can effectively avoid the excessive use of O type washing RBC.
