HLA-DRB1 genotyping in children with nephrotic syndrome of non-IgA mesangial proliferative giomerulonephritis / 中华微生物学和免疫学杂志

ABSTRACT

Objective To investigate the association of HLA-DRB1 alleles in Han population of Shanxi childrcn with nephrotic syndrome of non-IgA mesangial proliferative glomerulonephritis (MsPGN). Methods HLA-DRB1 was performed by polymerase chain reaction-sequence specific primers technique, and twenty patients with nephrotic syndrome of non-IgA MsPGN were detected. Results Analysis of the fre- quencies of specific at the HLA-DRB1 loci revealed significantly higher frequencies of HLA-DRB1 * 11 al- leles among the nephrotic syndrome patients of non-IgA MsPGN comparing with controls (22. 50% vs 8.33%, x2= 9. 544, P = 0.002, CI = 1. 674-9.995, RR = 4.09). Nine patients with HLA-DRB1 * 11 all accompanied hematuria, hypertension or short renal insufficiency. Conclusion The results suggested that HLA-DRB1 * 11 alleles contribute to genetic susceptibility to nephritic syndrome of non-IgA MsPGN. The pa- tients with HLA-DRB1 *11 easy accompanied hematuria, hypertension or short renal insufficiency.
