title: [Diagnostic value of LDH-isoenzyme determination in the urine].
abstract: In patients with chronic pyelonephritis (n = 17), nephrotic syndrome (n = 7) and hyperthyroidism in comparison to a reference group of healthy persons (n = 17) total activity and isoenzymes of the lactate dehydrogenase in the urine were determined. Only in patients with pyelonephritis is not regularly increased activity of the total lactate dehydrogenase a clear increased excretion of the isoenzymes IV and V is established. The isoenzyme pattern shows a dependence on the content of leucocytes in the urine and normalizes in renal infections only in a therapeutic effect.
