Production of recombinant human beta2-microglobulin for scintigraphic diagnosis of amyloidosis in uremia and hemodialysis.
Amyloid of beta2-microglobulin (beta2m) origin can be diagnosed using 131I-radiolabelled-beta2m scintigraphy in patients with uremia and hemodialysis treatment. As the tracer beta2m is isolated from another patient, it carries the common risks, including viral infections such as Hepatitis B, C and HIV, which are associated with human plasma products. In order to exclude these risks we have prod...
متن کاملSubcutaneous beta2-microglobulin amyloid shoulder nodulesin a long-term hemodialysis patient.
beta2-Microglobulin accumulation with resultant tumor formation is a known albeit rare complication of long-term hemodialysis. Although these tumors may occur in various locations, subcutaneous shoulder nodules are very infrequent. We report a patient with end-stage kidney failure who had been on hemodialysis for 16 years and noted left shoulder nodules after initiation of hemodialysis; these n...
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...
