Idiopathic immunoglobulin A (IgA) nephropathy is characterised by an extreme variability in clinical course, leading to end-stage renal failure in 15-20% of adults. This subgroup of patients with IgA nephropathy is usually included in the waiting lists of organ exchange organisations. The frequency of HLA-A,B,DR antigens of this subset of IgA nephropathy patients was calculated and compared to controls. The antigens HLA-B35 and DR5 were significantly increased in the patients with relative risk values of 1.385 and 1.487, respectively. The antigens HLA-B7, B8, DR2, and DR3 were found in a significantly lower frequency in the patients as compared to the controls. The relative risk (RR) values ranged between 0.695 and 0.727. Consequently, the haplotypes HLA-A1, B8, DR3, HLA-A3, B7, DR2, HLA-A2, B7, DR2 together with HLA-A1, B15, DR4, HLA-A9, B12, DR7, and HLA-A10, B18, DR2 were found to be protective with RR values ranging from 0.309 to 0.587. The only susceptible haplotype observed was HLA-A2-B5, DR5 (RR=2.990).

UI MeSH Term Description Entries
D007676 Kidney Failure, Chronic The end-stage of CHRONIC RENAL INSUFFICIENCY. It is characterized by the severe irreversible kidney damage (as measured by the level of PROTEINURIA) and the reduction in GLOMERULAR FILTRATION RATE to less than 15 ml per min (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002). These patients generally require HEMODIALYSIS or KIDNEY TRANSPLANTATION.

D011110 Polymorphism, Genetic The regular and simultaneous occurrence in a single interbreeding population of two or more discontinuous genotypes. The concept includes differences in genotypes ranging in size from a single nucleotide site (POLYMORPHISM, SINGLE NUCLEOTIDE) to large nucleotide sequences visible at a chromosomal level.

D005922 Glomerulonephritis, IGA A chronic form of glomerulonephritis characterized by deposits of predominantly IMMUNOGLOBULIN A in the mesangial area (GLOMERULAR MESANGIUM). Deposits of COMPLEMENT C3 and IMMUNOGLOBULIN G are also often found. Clinical features may progress from asymptomatic HEMATURIA to END-STAGE KIDNEY DISEASE.

D006650 Histocompatibility Testing Identification of the major histocompatibility antigens of transplant DONORS and potential recipients, usually by serological tests. Donor and recipient pairs should be of identical ABO blood group, and in addition should be matched as closely as possible for HISTOCOMPATIBILITY ANTIGENS in order to minimize the likelihood of allograft rejection.

D006680 HLA Antigens Antigens determined by leukocyte loci found on chromosome 6, the major histocompatibility loci in humans. They are polypeptides or glycoproteins found on most nucleated cells and platelets, determine tissue types for transplantation, and are associated with certain diseases.
