Bone morphological parameters of renal osteodystrophy such as abundance of osteoid surface, osteoid seam width index, calcification fronts, osteoclast activity and trabecular bone volume were studied in 71 patients on maintenance hemodialysis and compared with bone densitometry, laboratory and clinical data. Increased osteoclast activity (hyperparathyroidism) was by far the most common bone morphological finding. Patients with chronic pyelonephritis or polycystic kidney disease had more than double the amount of osteoid than patients with chronic glomerulonephritis. The trabecular bone volume seemed to be increased in most patients in contrast to the cortical bone volume which was decreased, judged from bone densitometry and previously from X-ray. Despite that patients with polycystic kidney disease were older, their trabecular volume was larger than in patients with glomerulonephritis. The bone mineral content evaluated by bone densitometry was low in most patients, and more associated with bone morphological signs of osteomalacia than with secondary hyperparathyroidism. Serum phosphate (S-PO4) and serum parathyroid hormone (S-PTH) seemed to discriminate better between osteomalacia and secondary hyperparathyroidism than serum alkaline phosphatase (S-Alk. phosph.), which was elevated in both groups. Patients who had been bilaterally nephrectomized were no more abnormal than other patients, and they had lower S-Alk. phosph. The abundance of osteoclasts was found to be a predictor of future development of clinical secondary hyperparathyroidism.

Concentration and acidification capability was tested in 41 patients with chronic pyelonephritis (PN), 14 patients with chronic glomerulonephritis (GN), 16 patients with diabetic nephropathy (DNP) and 12 healthy controls. Significant differences appeared between PN and GN, PN and DNP comparing a quotient between percent of normal osmolarity and percent of normal creatinine clearance. Similar results were obtained using a quotient creatinine clearance/ammonia excretion, which enabled the differentiation of PN from the other groups. The tubular functions of concentration and ammonia excretion in relation to creatinine are clinically useful in the differentiation of pyelonephritis from glomerular kidney diseases.

For the judgment of the success of the immunosuppressive therapy of chronic glomerulonephritis 400 patients (242 males and 158 females) at an average age of 31.2 years were examined after an average duration of treatment of 31.9 months. Apart from the renal function (serum creatinine), the histological and immunohistological form of the glomerulonephritis for the valuation further clinico-paraclinical data were taken into consideration: proteinuria, nephrotic syndrome, arterial hypertension and the combination of nephrotic syndrome and arterial hypertension. At the beginning of the treatment 293 of 400 patients (73.2%) had a normal renal function, 107 of 400 patients (26.8%) were initially renal-insufficient. 16 of 400 patients (4.0%) had additionally a pyelonephritis and 12 of 400 patients (3.0%) had a lupus nephritis. 27 of 400 patients (6.9%) developed a terminal renal insufficiency after an average duration of observation of 40.5 months. Complications caused by therapy were registered in 104 of 400 patients (26.0%). Recommendations for the present therapy of chronic glomerulonephritis are formulated.

We studied 182 patients with chronic renal failure by urinalysis and urine cultures. Of the patients 27 per cent had significant bacteriuria (more than 10(5) per ml.), 38 per cent had significant pyuria (more than 10 white blood cells per high power field), 19 per cent had urinary tract infection and 7 per cent had symptomatic urinary tract infection. All 12 patients with symptomatic urinary tract infection had significant bacteriuria and 11 had significant pyuria, while 1 had 5 to 10 white blood cells per high power field. Incidences of urinary tract infection differed depending on the primary renal disease (12, 13, 41 and 67 per cent for chronic glomerulonephritis, diabetic nephropathy, polycystic kidney and chronic pyelonephritis, respectively). Among the patients with chronic glomerulonephritis no significant differences were seen in frequencies of bacteriuria and urinary tract infection between male and female patients or between those who did and did not undergo hemodialysis. Also, no significant correlation was seen between bacteriuria and daily urine output but pyuria was significantly more frequent in oliguric patients or those on hemodialysis.

The rate of progression of early renal failure was evaluated in three groups of adult patients with renal disease of diverse etiology on dietary protein and phosphorus restriction (about 0.6 g/kg of protein, 700 mg of phosphorus) and in a control group of 22 patients with the same renal disease, retrospectively studied, on a free diet. Group 1 had 33 patients with chronic glomerulonephritis (CG), initial serum creatinine (Scr) of 1.4 to 4.3 mg/dl (mean, 2.20), followed for 5 to 94 months (mean, 44). Group 2 had 17 patients with polycystic kidney disease (PKD), Scr 1.3 to 4.7 mg/dl (mean, 2.40), followed for 8 to 81 months (mean, 42). Group 3 had 28 patients with primary chronic pyelonephritis (CP), Scr of 1.5 to 4.5 mg/dl (mean, 2.57), followed for 9 to 92 months (mean, 41). The control group had 22 patients (11 with CG, five with PKD, and six with CP), with Scr 1.7 to 4.1 mg/dl, followed for 6 to 72 months (mean, 24). In the regression analysis between reciprocal creatinine and time, the slopes were -0.0017, -0.0025, and -0.00016 dl/mg/month in the three patient groups on a protein-restricted diet, respectively. The difference between both groups 1 and 2 and group 3 was statistically significant (P less than 0.05). The slopes in patients on a free diet were significantly greater than those found in patients on a protein-restricted diet. The actuarial survival probability at 72 months, assuming as "renal death" a Scr of 10 mg/dl, was 45% in patients with CG, 44% in those with PKD, and 67% in those with CP on a protein-restricted diet.(ABSTRACT TRUNCATED AT 250 WORDS)

R-R variations in the ECG were studied as a sign of autonomic dysfunction in 44 non-diabetic patients with terminal uraemia treated with intermittent haemodialysis. A severe impairment of this parasympathetic vagal reflex was found though there were only mild signs of diffuse polyneuropathy. No acute effect was associated with haemodialysis. There was no correlation between either the R-R variations and the polyneuropathy-index or the total dialysis time. Patients with chronic glomerulonephritis, pyelonephritis and polycystic kidney disease were equally affected.

Morphology of nephrosclerosis at the early stage of its development is characterized by its nosological specificity which is determined by qualitative alterations and by the degree of renal structural components involvement into the sclerotic process. Complex morphometric assessment allows one to reveal and make it objective the morphological differences between nosological variants of nephrosclerosis. All the structural renal components equally undergo sclerosis at the late stages of nephrosclerosis and this leads to the leveling off the nosological specificity in the majority of cases. Arterial hypertension in chronic glomerulonephritis and chronic pyelonephritis favours the progressing of the nephrosclerosis and leveling off its nosological differences.

This report describes the renal pathology in three siblings with hereditary nephritis. All three cases showed combined features of chronic glomerulonephritis, pyelonephritis, and interstitial nephritis. Foam cells were seen in only one case. These findings support the contention of Krickstein, Gloor, and Balogh (1966) that the renal changes in hereditary nephritis are those of a mixed nephritis.

Glucose titration studies were performed on 17 patients with either chronic pyelonephritis or chronic glomerulonephritis. Glomerular filtration rates for the group ranged from 4.3 to 58.1 ml per minute. In none of the patients in whom the glomerular filtration rate was over 15 ml per minute was there appreciable splay, and the mean titration curve for these patients resembled that obtained by Smith and associates in normal man (1). In half of this group of eight patients, GFR ranged from 16.6 to 22.7 ml per minute; in the other half values ranged from 42.3 to 58.1 ml per minute. Yet, the mean titration curves were identical for the two groups. In addition, no difference was observed in the titration curves for patients with pyelonephritis and those with glomerulonephritis. In patients with GFR values below 15 ml per minute, increased splay was observed, and below a GFR of 10 ml per minute, the splay was very marked. Both the absence of exaggerated splay in patients with reduction of glomerular filtration rate by as much as 85%, and the emergence of exaggerated splay in patients with more marked reduction of GFR, require explanation. Theoretical considerations are presented in the text.

Autopsies of all uraemic patients in Leningrad for three years, and materials of the City Nephrological Service have demonstrated that the structures of nephrological diseases in their early and terminal stages were different. Chronic glomerulonephritis has been noted in patients with normal renal function just as often as chronic pyelonephritis but the former prevails considerably among the causes of uraemia. The proportion of polycystic kidney disease, amyloidosis, and diabetic nephropathy increases in patients with chronic renal failure. Due to these changes and the difference in the death age of patients with various diseases the majority of patients suitable for treatment with long-term dialysis suffer from chronic glomerulonephritis and only 14.89-20.5% from chronic pyelonephritis.
