Excretion patterns of kidney related urinary proteins such as lysosomal beta-N-acetylglucosaminidase (beta NAG), brush-border Ala-(Leu-Gly)-aminopeptidase (AAP), gamma-glutamyl transpeptidase (GGT), and alkaline phosphatase (AP) as well as of IgG, albumin, and alpha-1-microglobulin, were assessed in patients with chronic glomerulonephritis (n = 53), pyelonephritis (n = 27), systemic lupus erythematodes (n = 5), and patients with essential arterial hypertension (n = 18). Excretion of tubular marker enzymes and serumproteins (related to urine creatinine concentration = protein creatinine index) in spontaneously voided second morning urine was significantly higher as compared to the controls (n = 2). Alpha-1-microglobulin was markedly elevated in both pyelonephritis and glomerulonephritis indicating disturbance in tubulointerstitial handling of microglobulins also in cases with primary glomerulopathy. Rise of albumin, IgG, and alpha-1-microglobulin as well as of tubular kidney markers AAP, AP, GGT, and beta NAG in cases with arterial hypertension without preexisting nephropathy support the hypothesis of a defect in charge and size permselectivity in these patients which is probably due to an increase in glomerular capillary perfusion pressure and hyperfiltration.

The activity of selected lysosomal hydrolases ( (beta-galactosidase, beta-N-acetylglucosaminidase, beta-xylosidase, alpha-mannosidase, alpha-fucosidase) was determined in the blood serum of patients with systemic lupus erythematosus (SLE). An increased activity of all the enzymes studied was found as compared to control subjects. Presumable mechanisms of the observed changes are discussed. It is suggested that the studied enzymes may be responsible for the desintegration of the connective tissue ground substance in SLE.
