Abstract:
【Objective】 To explore platelet antibody production and its influencing factors in common platelet transfusion diseases. 【Methods】 From January 2018 to June 2020, patients who applied for platelet transfusion in the First Affiliated Hospital of Chongqing Medical University were enrolled. The solid phase agglutination method was used to detect the platelet antibodies of the patients. The platelet antibody positive rate of common platelet transfusion diseases and the types of diseases with higher platelet antibody-positive rates were analyzed. 【Results】 The overall positive rate of platelet antibodies in transfusion candidates was 15.0%. The 21~40 years old age patients(21.5%), females(18%) had a significantly higher platelet antibody positive rate than other ages and males(12.1%) (P<0.05). Besides, patients with a history of blood transfusion and pregnancy also had a higher platelet antibody positive rate. Tumors, blood and hematopoietic organ diseases, and digestive system diseases have higher platelet antibody-positive rates, which were 24.0%, 18.3%, and 16.6%, respectively. The platelet antibody positive rate varies significantly in common platelet transfusion diseases. As to transfused patients stratified by diseases, the platelet antibody positive rate of myeloid leukemia(48.7%)was higher than that of other diseases(P<0.05). In comparison, the platelet antibody positive rate of non-transfusion patients with liver failure and miscellaneous diseases(46.7%)was higher than that of others (P<0.05). 【Conclusion】 The positive rate of platelet antibody is somewhat higher in female, 21~40 years old patients. History of blood transfusion is a key risk factor for the production of platelet antibodies.
