title: Renal handling of beta-2-microglobulin in renal disorders: with special reference to hepatorenal syndrome.
abstract: A study of serum beta 2-microglobulin and urinary beta 2-microglobulin in patients with liver and/or kidney disease was done to determine if such information is of diagnostic help. Serum concentrations and beta 2M/Cr clearance ratios are higher in patients with primary tubular disorders than in those with glomerular diseases, a finding unaltered by hepatic disease. These data suggest either an increased production or decreased tubular degradation of beta 2M, independent of the glomerular filtration rate (GFR), in primary tubular disorders. The marked increase in urinary beta 2-microglobulin that followed insertion of the peritoneal-jugular shunt is evidence that this procedure resulted in improvement of the GFR, in previously underperfused nephrons.
