Membranous glomerulonephritis (MGN) is the most common cause of idiopathic glomerulonephritis in American adults. African-Americans develop end-stage renal disease (ESRD) due to chronic glomerulonephritis four times more often than whites. To determine whether HLA phenotype associations existed in the subset of MGN patients with ESRD we analyzed HLA frequencies, by race, in patients with MGN entered in the Southeastern Organ Procurement Foundation registry between 1982 and 1992. HLA frequencies from 250 renal transplant patients with MGN (190 whites and 60 African-Americans) were compared with 4,506 race-matched cadaveric kidney donor controls (4,039 whites and 467 African-Americans). Race-specific odds ratios (ORs) were calculated and fitted into a log-linear model to determine associations between MGN and HLA frequencies. The reported values were considered significant (P < 0.05) after Bonferroni correction for multiple comparisons. HLA-DR3 and HLA-DR5 frequencies were increased in cases of both races compared with race-matched controls (race-combined ORs, 2.22 and 1.61, respectively; all P < 0.02). Interracial analyses revealed that HLA-DR7 frequency was decreased solely in whites with MGN (OR, 0.53; P < 0.04). The results of this study indicate that HLA-DR3 and HLA-DR5 are positively associated with ESRD due to MGN in patients of both races and that HLA-DR7 is negatively associated with MGN in whites. These analyses confirm the published reports of HLA-DR3 association with MGN in Chinese, French, British, Chilean, and American white populations. The novel association of HLA-DR5 may reflect the fact that the MGN cases in this study all had ESRD.(ABSTRACT TRUNCATED AT 250 WORDS)
