The renal acidosis may appear by a decrease of the number of nephrons able to function (decrease of the filtrate of the glomerulum) as well as by a selective alteration of the tubular acidification mechanism. In 66 patients with chronic renal insufficiency of different degrees of severity (32 patients with diabetic glomerulosclerosis, 18 patients with chronic glomerulonephritis and 16 patients with chronic pyelonephritis) studies of the parameters of the acid-base-state and the renal insufficiency were carried out. 53 of these patients had a pathologically changed acid-base-state which was most expressed in patients with chronic pyelonephritis. A characteristic relation between the renal function (creatinine clearance) and the change of the pH-values was observed. The regression curve of the pH-values was descending so that in clearance values below 25 ml/min in nearly all patients a pronounced acidosis was present. This could be proved in the patients with pyelonephritis already when higher clearance values were present. The forms of the development of the metabolic acidosis in chronic renal insufficiency are discussed.

A total of 150 patients with renal pathology (chronic glomerulonephritis, pyelonephritis, urolithiasis, etc.) accompanied by the development of psychoneurological disturbances were examined. In the initial stage of the renal insufficiency the authors observed neurasthenic, radicular, polyneuritic, renovisceral syndromes, in a more remote stage--encephalopathies and disturbances of the brain circulation. The important part in the above-mentioned disturbances is played by azotemia, metabolic acidosis, disturbances of fluid-electrolyte and albumine balance, as well as arterial hypertension.

There seems to be little doubt that FGS is a nonspecific lesion that represents one way in which the renal glomerulus responds to a variety of injuries. This is illustrated by the large number of diverse conditions with which the lesion is associated including various forms of glomerulonephritis, pyelonephritis, hereditary nephritis, and heroin usage. Nevertheless, there remains a relatively large isiopathic group which, though possibly heterogeneous, displays a number of characteristic clinical and pathologic features including the following: 1. Steroid-resistant nephrotic syndrome; 2. Hematuria and hypertension; 3. Normal serum complement; 4. Progressive renal insufficiency; 5. Typical pathologic lesion most common in or restricted to juxtamedullary cortex; 6. Absence of clearly defined evidence of immune complex deposition by immunofluorescent or electron microscopic studies; 7. Recurrence of the lesion following renal transplantation. The pathogenesis of these changes is unclear, the evidence for an immune complex mechanism meager, and the suggestion that the disease is mediated by a humoral mechanism remains to be explored. The potential recurrence of this lesion in the transplanted kidney affords a unique opportunity to study the disease early in its course by a variety of techniques that may help to clarify this still poorly understood entity.

Amongst the various methods suggested for the topographical diagnosis of urinary tract infection, the study of various fractions of lactico-dehydrogenase in the urine would appear to be particularly valuable. Study of 44 subjects with a significant urinary infection, compared with an identical group of subjects free of urinary infection, showed that in those with pyelonephritis fraction 5 was significantly (p less than 0.001) higher than in those with a lower urinary tract infection. However this was valid only in the absence of renal insufficiency. Combined study of immunological techniques (urinary antibodies revealed by immunofluorescence and serum antibodies) shows that these techniques are complementary and make it possible to exactly localise the site of a urinary tract infection. In relation to immunology, enzymology has the advantage of being suitable for use during periods at which bacteriological examination of the urine is negative, and hence is useful in following the influence of treatment.

25 (30%) out of 85 adult patients with endstage renal disease were found to have vesicoureteral reflux. In group I with 15 patients renal insufficiency was caused by kidney disease alone. In a second group 8 patients had the diagnosis chronic pyelonephritis with well documented history of urinary tract infection. In a third group 2 patients have megaloureter-megalocystis syndrome. There was no case of uncomplicated, sterile reflux in the second and third groups, which seems to be a rare cause of renal insufficiency.

The frequency of chronic pyelonephritis is often overestimated. Chronic pyelonephritis is probably always a secondary disease in cases with obstructive changes in the ureters or other primary renal damage. The influence of chronic infection on the progression of renal insufficiency is still not well understood today. Underlying disease and infection should always be taken into consideration in the treatment of chronic pyelonephritis.

Manifest infections with fungi of the urinary tract are rare in comparison with bacterial diseases and therefore they are often overseen. When this is concerned a funguria must always be clarified in chronic pyelonephritis. In patients with manifest infections with fungi without pronounced renal insufficiency 5-fluorocytosin is therapeutically very well suited on account of the renal elimination.

Twenty-six patients, 20 to 77 years of age, were treated with netilmicin, mean dose 2 mg/kg every 8 h intramuscularly or in a 20-min intravenous infusion. The mean serum half-lives in patients with creatinine clearances of >/=90 ml/min and 60 to 90 ml/min were 3.2 and 3.4 h, respectively. In patients with serum creatinines of </=1.4 mg/100 ml and creatinine clearances of >/=60 ml/min, mean serum levels were 9.0 and 1.2 mug/ml, respectively, 5 to 15 min and 7.5 h post-intravenous infusion, and 7.1 and 1.7 mug/ml, respectively, 1 and 8 h post-intramuscular injection. Twenty-five patients had acute pyelonephritis; 7 of the 25 had bacteremia. The infecting bacteria were Escherichia coli (15), Proteus mirabilis (5), Pseudomonas aeruginosa (2), Klebsiella pneumoniae (1), Enterobacter hafniae (1), and both Proteus rettgeri and Proteus morganii (1). All were inhibited by 6.3 mug of netilmicin per ml, except for the P. rettgeri, which required 25 mug/ml for inhibition. Of 23 patients who could be evaluated, 19 were bacteriologically and clinically cured at follow-up. Of the remaining four, one relapsed, two became reinfected, and one was lost to follow-up. Five patients developed nephrotoxicity; two of the five had previous renal insufficiency. Three patients, one with abnormal renal function, developed ototoxicity detected only with audiograms. These studies suggest that netilmicin is effective in serious gram-negative bacillary infections, but is nephrotoxic and ototoxic in humans.

In 4 out of 9711 (= 1:2400) patients, lactice acidosis due to biguanides was diagnosed. Serum lactate concentration averaged 18.2 mmol/l and the pH value 6.87. All patients showed signs of renal insufficiency and three had congestive heart disease. In addition to treatment with biguanides, other factors might have contributed to the lactice acidosis in these patients: prolonged fasting, severe dehydration due to persistent vomiting, acute bronchopneumonia, and acute pyelonephritis. On addmission, two patients were in shock and all patients were semi-conscious or comatose. All patients were treated with bicarbonate and glucose/insulin. One patient was hemodialysed. Two of our four patients died. Oour four patients are compared with 179 patients in the literature with respect to mortality and prognosis of lactic acidosis due to biguanides.

In patients with stone pyelonephritis the behaviour of the renal function under the influence of chemotherapy was examined at the stage of the compensated retention. 24 cures carried out on clinical conditions on 10 patients with an average age of 52 years (14--71) were evaluated. By means of chemotherapy in connection with the treatment of anaemia and the compensation of acidosis the renal function could favourably be influenced and the terminal stage of the renal insufficiency could be shifted. The author adopts a definite attitude to the long-term prophylaxis.
