Comparison of HLA antibody incidence in old, middle and young age patients / 中华微生物学和免疫学杂志

ABSTRACT

Objective To investigate the HLA antibody incidence and type renal recipients with different age, and to study the echaracteristics in different age patients, for clinical reference to forecast renal rejection in different age patients. Methods With serum dated from January 2006 to June 2008, patients were classified into three groups young group, with age below 35 years; middle age group, with age from 36 to 50 years; and old group, with age above 50 years. Penel reactive antibody (PRA) were detected using ELISA. Results Pretransplant HLA antibody incidences in the young, middle age, old group were 18.18%, 23.00% and 6.19%, respectively. In young group, HLA antibody incidences were 5.59% and 8.51% in male and female respectively. In middle age group, they were 21.30% and 25.38% in male and female respectively. In old group, they were 11.36% and 25.00% respectively. HLA Ⅰ and HLA Ⅰ + Ⅱ antibodies were mainly found in all the three groups in pretansplant. Conclusion HLA Ⅰ and HLA Ⅰ + Ⅱ antibodies were mainly found in pretransplant. Antibody incidence was higher in patients who had more than once renal transplant than that in transfusion and pregnancy female. Antibody incidence is higher in female than that in male.
