To investigate the presence of intraglomerular immunoprotein deposition in chronic pyelonephritis (CPN), 29 renal specimens from patients with various urological diseases were examined by immunofluorescence. The relationship between immunohistological findings and types of glomerular changes which were classified according to Heptinstall's criteria was studied. Only type 2 glomeruli, which were considered to be ischemic changes, demonstrated granular and globular depositions of IgM and C3 in the collapsed and solidified shrunken tufts. IgM was positive in 117 of 258 (45.3%), and C3 in 122 of 264 (46.2%) type 2 glomeruli. The distribution patterns of IgM and C3 were much the same. IgG and IgA were rarely observed and neither fibrinogen nor albumin was observed in the tufts of type 2 glomeruli. Normal glomeruli and other types of glomerular changes in CPN showed few or no intraglomerular immunoprotein deposition.

One hundred and forty-seven patients with essential hypertension (EH) and 126 patients with secondary arterial hypertension (AH) on the basis of chronic pyelonephritis were studied by means of radiocardiography with 131I-albumin and M-mode echocardiography. The importance of the haemodynamic type of circulation for the development of left ventricular hypertrophy (LVH) was established. Correlative analysis revealed that the influence of arterial pressure (AP) on LVH is increased by stabilization of AH, especially in patients with the normo- and hypokinetic types of circulation; interestingly, the relation between LVH and systolic pressure was closer than that between LVH and diastolic pressure, especially in patients with secondary AH. Moreover, it was shown that the development of LVH is due to a preferential increase in posterior wall thickness in essential hypertensives and in ventricular septal thickness in secondary hypertensives, although all patients with LVH had dilatation of the left ventricular cavity.

A 3-year-old boy with mixed glomerular/tubular proteinuria, mental retardation, and hyperkinesis is described. The proteinuria was discovered at the age of 3 years on urinary mass screening. Most of the urinary protein consisted of albumin, accompanied by increases in low molecular weight proteins, including beta 2-microglobulin and alpha 1-microglobulin. Mixed glomerular/tubular proteinuria is known to be caused by the following conditions: chronic renal failure, chronic pyelonephritis, cadmium poisoning, tubulointerstitial nephritis of various etiologies, and after strenuous, short-term, exhaustive exercise. The present patient did not display any of these disorders or conditions.

Urinary glycyl-prolyl dipeptidyl aminopeptidase (GP-DAP) activity was measured in 18 healthy adults and 252 patients with urological diseases. The GP-DAP activity was significantly higher in patients with prostatic cancer, bladder cancer or renal cancer and also in patients with acute prostatitis or pyelonephritis than in healthy adults. GP-DAP activity was also studied during anticancerous chemotherapy and proved to be a sensitive parameter for renal damage as are urinary N-acetyl-beta-D-glucosaminidase, alanine aminopeptidase, beta 2-microglobulin, alpha 1-microglobulin, and albumin. The analysis of tissue activities suggested that GP-DAP was located not only in the renal parenchyma but also in the prostate and seminal vesicles.

Fifty women with pyelonephritic renal scarring were prospectively followed for five years and the changes in renal function were related to blood pressure control, plasma renin activity, urinary albumin excretion and the incidence of urinary tract infections (UTI). Five patients (10%) developed end stage renal disease. All these patients had bilateral disease, proteinuria and anti-hypertensive treatment at presentation. The mean +/- SD glomerular filtration rate (GFR) of all patients with renal scarring was 74 +/- 27 ml/min x 1.73 m2 at presentation which was significantly lower than the GFR in 55 patients with a recent episode of acute pyelonephritis (p less than 0.001) and 10 healthy controls (p less than 0.001). GFR and age corrected GFR decreased significantly during follow-up (p less than 0.001) and p less than 0.02 respectively). The decrease in GFR was significantly higher in patients with bilateral scarring, in patients on blood pressure treatment and in patients with an episode of symptomatic UTI during follow-up. Eight patients (16%) had antihypertensive treatment at presentation and another 11 patients (26%), of whom 10 had bilateral scarring, developed hypertension (greater than 140/90 mmHg) during follow-up. Seventy-five per cent of all patients had symptomatic UTI and 40% had an episode of acute pyelonephritis during follow-up. In conclusion, patients with pyelonephritic scarring have a high incidence of UTI and are at high risk of developing renal failure and hypertension. It is essential that recurrent episodes of symptomatic UTI are treated promptly and that blood pressure is monitored carefully in these patients.

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.

A radionuclide method with quickly disintegrating 99MTC labelled human albumin and DTPA in a volume of 0.3-0.5 ml and activity of 37 mVk with two consecutive examinations of central and renal hemodynamics was used in 91 pregnant women with preeclampsia and pyelonephritis. Marked hypovolemia was found in all groups of investigated women with preeclampsia with the exception of the group of women with pyelonephritis. There was also difference in arterial pressure in women with preeclampsia I degree and pyelonephritis, which was statistically significant with advancement of gravity and duration of the disease. The investigation of the functional state of kidneys and blood flow showed a tendency to slowing both in the arterial and venous circulation in women with pre-eclampsia of pregnancy. In the pregnant women of this group and the women with pyelonephritis there was asymmetry in the curves of the blood flow as well as in the temporary indices of renal filtration, which were increases two-folds in comparison with the normal values. They were mostly manifested on the side of the involvement in women with pyelonephritis. Irradiation loading was 0.212 mZv of both examinations and was ten times less than that of x-ray pelvimetry.

A case of an 11-year-old boy is presented who had developed a severe nephrotic syndrome with massive edema, ascites, hydrothorax (protein loss with the urine up to 19 gr/24 h) 7 months after a successful kidney transplantation from a 16 years dead donor and a successfully treated crisis of transplant rejection by a good tissue compatibility. The needle renal biopsy revealed membranous glomerulonephritis I-II histological stage with data of rejection crisis by a basic disease of vesicoureteral refluxes and chronic pyelonephritis. Treatment with heparin, dipyridamole, human albumin, diuretics, sandimun and prednisolone led to a substantial improvement--mastered nephrotic syndrome, lowered to 1 g/24 h proteinuria and normal renal function.

Ninety-six children, aged 4 to 14, with congenital obstructive uropathies were subjected to 131I-hippuran renography, followed by mathematical processing of renographic curves, the measurement of blood mean molecular levels, and blood and urinary immunochemical tests before, and 1 month as well as 1 year after surgery. Intraoperative renal biopsy was taken from 20 patients with unilateral hydronephrosis. Latent chronic renal failure (CRF) was identified where a deficiency of total renal clearance of 131I-hippuran (20 to 56%) was combined with a rise in blood mean molecules from 0.3 to 0.41 conventional units at 254 nm. Latent CRF was detected in 40 of 64 children with unilateral uropathy and in all 32 patients with bilateral uropathy. In patients with unilateral hydronephrosis, the presence of CRF was unrelated to the morphological pattern of pyelonephritis in the affected kidney. Children with latent CRF showed high levels of urinary IgG and albumin and blood mean molecules. One year after the operation, renal function improved in patients whose contralateral kidney had no secretory deficiency. One year after surgery, renal reabsorption mechanisms tended to recover in CRF-free patients only. The clinical pattern of latent CRF and its elimination following surgery were unrelated to roentgenologic markedness of hydronephrosis and VUR, but were dependent on the recovery of compensatory mechanisms in the contralateral kidney. By the end of the first postoperative year, latent CRF was diagnosed in 31% of children with unilateral hydronephrosis (as compared to the preoperative 68%), 43% (vs. the preoperative 60%) of children with unilateral VUR, and in 44% (vs. the preoperative 50%) of patients with unilateral neuromuscular ureteral dysplasia.(ABSTRACT TRUNCATED AT 250 WORDS)

Patients with pyelonephritic renal scarring are at risk of developing renal failure and hypertension. We studied glomerular filtration rate (GFR), renal plasma flow (RPF), filtration fraction (FF), systolic (SBP) and diastolic (DBP) blood pressure, fractional sodium, potassium and phosphate excretion, peripheral renin activity (PRA), plasma aldosterone (p-Aldo), urinary albumin excretion (U-Alb) and urinary beta 2-microglobulin excretion (beta 2-M) in hydropenia and during transition to 3% volume expansion with isotonic saline infusion in 22 female patients with renal scarring due to pyelonephritis and 9 healthy controls. The patients had significantly lower GFR, higher SBP and higher PRA in hydropenia, but there was no significant difference in RPF, FF, DBP or p-Aldo. After volume expansion, SBP, DBP, PRA and p-Aldo were significantly higher in patients than in controls. Transition to 3% volume expansion was associated with a similar increase in SBP in both patients and controls, whereas DBP increased significantly more in the patients (p less than 0.01). Volume expansion resulted in a significant suppression of PRA and p-Aldo in both patients and controls. The patients with renal scarring had the same capacity to excrete sodium and water during transition to volume expansion as the healthy controls. The renin-aldosterone system seems abnormally activated and is probably more important than hypervolemia in the development of hypertension in this group of patients.
