ABSTRACT
Objective To detect and analyze the distribution characteristics of platelet antibodies in inpatients and explore the causes of platelet antibodies, so as to provide data support for improving the quality of blood transfusion. Methods A total of 38 840 patients were selected. The platelet-related antibodies were detected by Capture-P solid-phase detection system, and the positive rate of antibodies was analyzed statistically. Results Of the 38840 inpatients, 3989 were positive for platelet antibodies, with a positive rate of 10.27%. The positive rates of male and female patients were 8.7% and 11.5%, respectively. The positive rate of platelet antibodies in patients under 18 years old was 6.98% which was significantly lower than that in patients ≥66 years old and 18~65 years old. The positive rates of patients with pregnancy history and blood transfusion history increased significantly, which were 14.4% and 14.7%, respectively. The positive rate of patients with blood system diseases and liver cirrhosis with gastrointestinal bleeding diseases was over 20%. The positive rates of patients in the Hematology Department, Intensive Care Department and Obstetrics Department ranked the top three, with the positive rates of 15.17%, 14.97%, and 13.67%, respectively. The positive rates of platelet antibodies in patients with blood types B and AB were lower than those in patients with blood types A and O. Conclusion In clinical platelet transfusion, the influence of the patients’ age, gender, hospitalized diseases, hospitalized department and other factors on platelet antibodies should be considered to reduce the occurrence of platelet transfusion refractoriness.
