8 patients with chronic pyelonephritis were given gentamycin intramuscularly injected in individual dosage during 8-10 days. Here the behaviour of the excretion of protein, alanine aminopeptidase alkaline phosphatase, alpha-glucosidase, gamma-glutamyl transpeptidase and lysozyme with the urine was tested. With the exception of the lysozymuria, which increased only in patients with chronic renal insufficiency, regularly a hyperenzymuria developed. Most distinctly the excretion of the alanine aminopeptidase increased. After initial decrease the excretion of total protein transiently increased after completion of the gentamycin therapy. All the deviations were reversible. From the increased excretion of enzymes may not be concluded to a nephrotoxicity of gentamycin.

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.

Reactive oxygen species have been found to be responsible for the tissue injury caused in experimental pyelonephritis in mice. The extent of lipid peroxidation (as assayed by malondialdehyde formation) was found to be increased significantly (p less than .001) in the infected group as compared to the normal mice. Superoxide dismutase and catalase (oxygen free radical scavengers) showed a significant decrease (p less than .001) in the extent of lipid peroxidation even in the presence of infection. Dimethyl sulfoxide, a hydroxyl ion scavenger, was however found to be effective only at 4 and 7 days postinfection (p less than .001). Allopurinol, an inhibitor of xanthine oxidase, did not significantly (p greater than .05) inhibit the formation of lipid peroxides, even upto 7 days postinfection. There was a significant decrease (p less than .05) in the activities of renal brush border membrane enzymes used as markers of renal tissue damage (i.e. alkaline phosphatase, leucine amino-peptidase and gamma-glutamyl transpeptidase) in the infected group as compared to the normal group. In the presence of superoxide dismutase, dimethylsulfoxide and catalase except allopurinol, the activities of all the enzymes but maltase were found to be increased significantly (p less than .05) as compared to the infected group. There was a significant increase (p less than .01) in the bacterial count in the presence of superoxide dismutase and DMSO in infected mice as compared to the infected control mice. However, no significant difference was observed in the catalase and allopurinol treated groups.

The combined enzymological investigation including determination of the total activity of asparagine transaminase and alanine transaminase, two serum enzymes, alkaline phosphatase, gamma-glutamyl transpeptidase, acetyl cholinesterase, and butyryl cholinesterase was applied to two groups of pregnant women with pyelonephritis treated with ampicillin (12 patients) and roscillin (14 patients). The investigation was performed at the following stages: before the treatment, on the 7th and on the 12th day of the treatment. No statistically significant differences in the average values of the activity of the above enzymes at these stages were observed in patients of the both groups which indicated the absence of the hepatotoxic effect of the preparations on the patients of a group as a whole. An increase in the levels of transaminases recorded in some patients after discontinuation of the treatment course was evident of a possible cytotoxic effect of the drugs without the signs of cholestasis. The effect was connected with the initial functional renal insufficiency.

The gamma-glutamyl transpeptidase (EC 2.3.2.2) activity of the urine was determined in 369 cases, with L-gamma-glutamyl-p-nitranilide as substrate. Thermally stable, low molecular mass inhibitors were removed by dialysis. The enzyme activity was found to have a mean of 10.57 U/l for the normal neonate population, and a mean of 16.92 U/l for children. A significant increase in activity was observed in pyelonephritis, Alport's syndrome, Wilms' tumour and glomerulopathies. The highest activities were found in kidney diseases associated with renal insufficiency. This non-invasive test can be used for the evaluation of tubular disorders in childhood.

Urinary excretion of the low molecular weight protein beta 2-microglobulin and tubular enzymes--alanine aminopeptidase (AAP), gamma-glutamyl transpeptidase (gamma-GT) and alkaline phosphatase (AP)--are very sensitive parameters for proximal tubular lesions. In patients with preeclampsia the renal excretion of beta 2-microglobulin allows to differentiate between a primary preeclampsia and a preeclampsia superimposed upon chronic pyelonephritis. In the first group the increase is 3- to 4-fold and in the second group up to 300-fold. In patients with kidney transplantation the urinary excretion of beta 2-microglobulin, AAP, gamma-GT and AP are several times higher than in normals. In case of a rejection episode a further increase of these proteins occur in more than 80% several days before clinical symptoms are present. The application of analgetics (paracetamol, acetylsalicylic acid) in healthy individuals in therapeutical dosages on 3 consecutive days does not show any tubular alteration by the measurement of urinary beta 2-microglobulin. Aminoglycosides (tobramycin, UK 18,892) lead to a cumulative increase of the renal excretion of beta 2-microglobulin and AAP while cephalosporins induce an increase of total proteins in the final urine under the same conditions.
