Abstract. The aim of the present study was to investigate the association of human leukocyte antigen (HLA) gene polymorphism and clinical phenotypes of patients with mesangial proliferative glomerulonephritis (MsPGN). The genotyping of HLA-A, HLA-B and HLA-DRB1 alleles was detected in 1,536 consecutive MsPGN patients during the previous five years and 2,027 age-and gender-matched healthy individuals by using the polymerase chain reaction-sequence-specific primers method. The clinical and pathological data of the patients were collected and the genotype frequencies (GF) and odds ratio (OR) were analyzed. The allele frequencies of HLA-A*23, A*25, B*15, B*40, B*53 and DRB1*18 were significantly higher in MsPGN patients than in the controls (P<0.05). These alleles were considered as the suspected susceptibility genes (SSG) for MsPGN. Of note, results of the follow-up survey study demonstrated poorer prognosis of patients with SSG than those without SSG.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
