Serum beta2-microglobulin level is a significant predictor of mortality in maintenance haemodialysis patients.
BACKGROUND Beta(2)-microglobulin (beta(2)-M) is recognized as a surrogate marker of middle-molecule uraemic toxins and is a key component in the genesis of dialysis-associated amyloidosis. Few studies have evaluated the association of beta(2)-M levels with clinical outcome in dialyzed patients. METHODS The prognostic implication of serum beta(2)-M levels for the survival of haemodialysis pati...
متن کاملSerum beta2-microglobulin values among healthy Brazilians using a DPC IMMULITE assay.
PURPOSE The present study was designed to determine the normal range of serum beta 2-microglobulin (Sb2M) levels among healthy volunteers in Brazil. Levels of Sb2M are elevated in human immunodeficiency virus (HIV)-infected patients and have been shown to be the best predictor of HIV infection status and of some malignant disorders, especially multiple myeloma. In order to achieve its optimal u...
متن کاملPlasma and urinary levels of beta2 microglobulin in rheumatoid arthritis.
Plasma and urinary levels of beta2 microglobulin have been investigated in 21 patients suffering from rheumatoid arthritis (RA). Despite a normal renal glomerular function in all patients 50% of them had supranormal plasma beta2 microglobulin levels and 30% had a higher than normal urinary output of beta2 microglobulin generally related to the high plasma level. Plasma beta2 microglobulin level...
متن کاملAtypical haemochromatosis: phenotypic spectrum and beta2-microglobulin candidate gene analysis.
Beta2-microglobulin was investigated in atypical haemochromatosis patients not homozygous for the C282Y mutation of HFE (OMIM *235200), because the HFE protein binds beta2-microglobulin, and in mice beta2-microglobulin gene knockout causes hepatic iron overload. Six unrelated patients with atypical haemochromatosis were studied. Five patients had normal HFE coding sequence and the sixth was het...
متن کاملA single disulfide bond differentiates aggregation pathways of beta2-microglobulin.
Deposition of wild-type beta2-microglobulin (beta2m) into amyloid fibrils is a complication in patients undergoing long-term hemodialysis. The native beta-sandwich fold of beta2m has a highly conserved disulfide bond linking Cys25 and Cys80. Oxidized beta2m forms needle-like amyloid fibrils at pH 2.5 in vitro, whereas reduced beta2m, at acid pH, in which the intra-chain disulfide bond is disrup...
