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.

In 12 cases with uremia, the electrical activity and form and amplitude of Bcg (displacement) were investigated before and after hemodialysis. The uremia was secondary to chronic glomerulonephritis (9 cases), familial nephritis (1 case), polycystic kidney disease (1 case) and chronic pyelonephritis (1 case). During the study digitalis was not given to the patients. The ECG and Bcg abnormalities were irreversible in most cases. In 9 cases the VCG showed hypertrophy of the left ventricle. Considering these facts it is assumed that myocardial hypertrophy might play an important part in the development of irreversible pathological repolarization and hemodynamic troubles in chronic uremia.

The presence of circulating soluble complexes antigen-antibody was investigated by means of our simple test (1) in small serum samples of patients before and after kidney transplantation. We found a higher incidence of positive test results in patients with an original diagnosis of chronic glomeruleonephritis following transplantation in 37.1%, than before transplantation (in 28.5%). In both instances, however circulating immune complexes were less frequent than in a previously studied group of patients with chronic glomerulonephritis (66.6%), or particularly in glomerulonephritis cases with the characteristics of disease activity (100%) positivity. In patients suffering from pyelonephritis, a diseases not due to immune complexes, 18% of sera were positive. After transplantation the number of positive sera rose to 35.5% in 13 patients. The reasons for this finding are being analysed.

From July 1967 to September 1974, 26 kidney transplantations were carried out in 16 children aged 6 to 17 years, in Gotherburg. The average age at the primary transplantation was 12 years and average body weight 29.7 kg. Five patients had familial juvenile nephronophthisis, 5 chronic glomerulonephritis, 5 chronic pyelonephritis, and one bilateral Wilms's tumour. Four patients were predialytic. Fourteen grafts came from living related donors. The surgical technique was standard as was the immunosuppression with azathioprine and cortisone; exceptionally antilymphocyte globulin was used. Thirteen patients were alive in September 1974, observed 2-65 months, 8 with a normal serum creatinine, 3 with moderately elevated serum creatinine, and 2 on hemodialysis. The 6- and 12-month survivals of patients are 100% and 93% respectively. Normal growth and full rehabilitation in recipients of functioning grafts make renal transplantation justified as a therapeutic procedure in terminally uremic children.

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.

The investigation covers the necropsic material of the Pathological Anatomy Chair, Medical Academy-Sofia, with a total of 3519 necropsies for a period of 5 years (1968--1970). In that material, 285 cases with uremia were established, due to chronic renal diseases, which might be referred to 13 nozological entities. The highest number of cases are with chronic pyelonephritis (64,96 per cent). The chronic glomerulonephritis, though it ranks second, is considerably rarely met (9,47 per cent). Endemic nephropathy, according to the incidence, follows--4,21 per cent, nephropathy in diabetes mellitus--3,86 per cent, subacute glomerulonephritis--3,16 per cent, amyloidosis--2,81 per cent, hypertonic disease--2,81 per cent, malignant tumors of the kidneys--2,81 per cent cystic kidneys--2,10 per cent, lupus erythematosus--1,05 per cent, sclerodermia--0,70 per cent, myeloma disease--0,70 per cent and polyarteriitis nodosa--0,35 per cent. As to the chronic renal disease, most frequently met in the material discussed, the chronic pyelonephritis, the authors discuss the factors that played certain role in its development as well.

Proportions and total numbers of peripheral blood T and B lymphocytes as well as their activity measured in the leukocyte migration inhibition test were estimated in 47 patients with acute or chronic glomerulonephritis and in 30 individuals serving as a control group. The obtained results indicated that glomerulonephritis was associated with altered proportions of peripheral blood lymphocytes. In acute glomerulonephritis high B lymphocyte levels were found while chronic proliferative glomerulonephritis was characterized by high proportions and high absolute levels of T lymphocytes. Few months observation of T: B lymphocyte proportions during the disease indicated that exacerbation of the disease was associated with lowered proportions of T lymphocytes. Moreover, it was shown that cell mediated hypersensitivity to GBM antigens was detectable in 80% patients with glomerulonephritis and was absent from patients with pyelonephritis. The latter results indicate participation of cell-mediated hypersensitivity in pathomechanisms of glomerulonephritis in most of the patients.

Thirty six patients with chronic glomerulonephritis, 35 -- with chronic pyelonephritis, 5 -- with diffuse glomerulonephritis with systemic lupus erythematosus and 60 healthy subjects were examined with the method by sedimentation with 3.5 per cent solution of polyethyleneglycol for the determination of circulating immune complexes. The average value for the healthy subjects is X = 0.123 +/- 0.047 mg/ml. The average value plus two standard deviations = 0.217 mg/ml is accepted as normal in healthy subjects. An elevated level of circulating immune complexes is found in 60 per cent of the patients with lupus nephritis and 25 per cent of the patients with chronic glomerulonephritis. The average values for the last two groups are X = 0.475 +/- 0.554 mg/ml and X = 0.184 +/- 0.185 mg/ml respectively. Whereas in the patients with lupus nephritis the values for the single patients are considerably over the adopted norm, in patients with chronic glomerulonephritis, in the majority of the cases, they are about its upper limit.

Follow up studies in 19 diabetic patients with manifestation in the youth. Proteinurie within few years; later on nephropathy: 7 cases with glomerulosclerosis, 8 with arteriolosclerosis, 3 with pyelonephritis and 1 with chronic glomerulonephritis. In all cases retinopathy, very often coronarsclerosis, seldom peripheral and cerebral sclerosis. 14 patients died, mostly in young age in consequence of nephropathy. Proteinurie is a malignant symptom of diabetic angiopathy; in contrast to the retinopathy.

The latent and hypertonic forms of the course of compensated nephritides more frequently make difficulties concerning the differential diagnosis between a chronic glomerulonephritis and a chronic pyelonephritis. According to the results achieved the determination of the renal processes furthering homoeostasis gives the possibility to demarcate the two diseases. A certain reduction of the creatinine clearance (to less than 90 ml/min) and of the maximum water diuresis (to less than 10.0 per 100 ml glomerular filtrate) is suitable for the latent form of the chronic glomerulonephritis. On the other hand, a reduction of the ammonia secretion (to less than 35 per 100 ml glomerular (filtrate) and of the total H+-ion secretion (to less than 50 per 100 ml glomerular filtrate) in the determination after Alkinton is characteristic for the chronic pyelonephritis. In the hypertensive form of the course of the chronic glomerulonephritis in contrast to the same form in chronic pyelonephritis a reduction of the maximum water diuresis to less than 7.5, of the clearance of the "osmotically free" water to less than 6.0, of the titrable acidity to less than 25 is the result. Here the ammonia quotient transgresses 45%. In chronic pyelonephritis the titrable acidity in considerably increased and the ammonia genesis relatively decreased (to less than 45%).
