There is evidence suggesting that IgA nephropathy (IgAN) is an immunological disease. The role of FILA class II DR beta 1 (DRB1) has previously not been well studied. The aim of our study was to investigate the association of HLA-DRB1 variants with IgAN in a Swedish Caucasian cohort. Our study consisted of 213 patients with biopsy proven IgAN, all of self-reported Caucasian ancestry. As a control cohort, 1569 healthy subjects from the same population in Sweden were included. HLA-DRB1 low-resolution genotyping was performed and odds ratios were calculated to assess the risk. less thanbrgreater than less thanbrgreater thanIn an allelic model the HLA-DRB1*03 and *10, demonstrated association for IgAN after correction for multiple comparison, with subsequent OR = 0.54 (95% CI 0.37-0.78) and 3.44 (95% Cl 1.67-7.07). When the influence of risk allelic groups was adjusted for protective allelic groups and vice versa, only a protective effect of HLA-DRB1*03 remained significant. less thanbrgreater than less thanbrgreater thanIn conclusion, the variants of HLA-DRB1 were associated with IgAN of which the HLA-DRB1*03 revealed a strong protective effect for IgAN. Our data replicates finding from other Caucasian populations and suggest that involvement of adaptive immunity may be of importance in the development of the disease.
