Diabetic patients with chronic renal failure are known to be at risk for exacerbation of renal failure if they undergo intravenous pyelography (IVP). The present report demonstrates that diabetic patients with normal serum creatinine levels can sustain irreversible renal failure following an IVP. The experiences with this case suggest that, if the creatinine clearance is decreased in an insulin-dependent patient irrespective of the serum creatinine value, one must be aware of the possible hazard of acute renal failure and irreversible renal damage following the IVP. This would appear to be especially true if the diabetic patient has proteinuria in combination with the decreased creatinine clearance.

Herein we discuss oliguria and azotemia in neonatal patients associated with perinatal complications, including difficult labor and delivery, and respiratory asphyxia. Renal failure in these patients is accompanied by proteinuria, microscopic hematuria and red blood cell casts, and it generally resolves in 7 to 10 days. Umbilical aortography can be helpful in determining the presence of normal kidneys in these patients.

The clinical course of IgA Mesangial Deposits Glomerulonephritis (MDGN) has been investigated in 178 patients for 1 to 32 years (mean 6 years) from the onset of symptoms. Impairment of renal function occurred in 28 patients, 13 of whom required RDT or died in uraemia. Hypertension was observed in 67 patients. The actuarial survival rate at ten years was 91%. A significant correlation was observed between the occurrence of renal failure and the following features: absence of episodes of gross haematuria, early appearance of hypertension, marked proteinuria and sclerosing glomerular lesions. These data suggest that IgA MDGN has generally a very prolonged course, but in a few cases may evolve, sometimes early, to chronic renal failure.

Subtotal nephrectomy in the rat is followed by glomerular hypertrophy, glomerulosclerosis, and, ultimately, renal failure. To gain more insight into this sequence, we have made a morphometric study of the glomerular changes following subtotal nephrectomy in the rat during the period of functional compensation before glomerulosclerosis appears. We found a twofold increase in glomerular volume as compared with controls 2 weeks after operation (to approximately 2 X 10(6) cu mu) followed by a linear increase to approximately 5 X 10(6) cu mu at 21 weeks. The rate of increase in glomerular volume in controls did not significantly exceed that of body weight. The volume increase after subtotal nephrectomy is a true hypertrophy, since other morphometric parameters expressed per unit glomerular volume (surface and length densities) were approximately 80% of control values at 2 weeks and constant thereafter. Glomerular hypertrophy up to 21 weeks is accompanied by a stable BUN and a gradually increasing proteinuria. We conclude that glomerular hypertrophy in this system is a pathologic rather than a compensatory process and suggest that it may represent a counter-productive response to hemodynamic changes serving to increase the glomerular filtration rate.

Amylase to creatinine clearance ratios were measured in 66 patients with a variety of moderate and severe renal diseases including 10 patients with renal transplants, and in 13 healthy controls. Only in patients with severe renal insufficiency (serum creatinine level above 660 micronmoles/1) were the amylase to creatinine ratios significantly raised. The ratios correlated neither with the type of renal disease, i.e. glomerular or tubulointerstitial, nor with the degree of proteinuria. Patients with renal transplants did not differ from other patients. Clearance ratios of pancreatic and salivary isoamylase to creatinine changed in parallel to that of total amylase. The results suggest that in severe renal failure the loss of nephrons results in decreased fractional reabsorption of amylase in the tubules.

One case of lecithin cholesterol acyltransferase (LCAT) deficiency is discovered by renal biopsy. Through the study of a French family, native to Brittany, one sister is found to be carrier of the trait. This finding suggests that the gene defect hitherto reported from Scandinavia is not restricted to this region. The patient shows typical signs of the disease, corneal opacities, anemia with a hemolytic component and lack of plasma LCAT activity. She has proteinuria, HTA, hematuria, no renal insufficiency. Signs previously unreported were noted: sensorineural hearing loss and platelet environment disorder. Histological abnormalities of two types are found: foam cells and subendothelial deposits, of which the tinctorial characteristics indicate a lipid composition. The lack of glomerular fluorescent staining observed is not in favor of an immune complex nephropathy. The study of this case suggests the determining role of lipid abnormalities in the genesis of anemia and of the vascular depositions in the induction of renal failure encountered in several cases of LCAT deficiency.

The clinical course of diabetic nephropathy was evaluated in 150 patients and the effect of hemodialysis in 68 of them. Proteinuria was the first sign of renal disease. Once renal dysfunction becomes evident, there is a rapid deterioration leading to dialysis within 3.0 +/- 0.2 years. Hypertension and circulatory congestion are common complications. The hypertension is probably volume dependent. Retinopathy was not invariably present at the onset of renal insufficiency but appeared with progression of renal failure. The course during hemodialysis was complicated by continued progression of diabetic vascular disease manifested by vascular access difficulties, worsening of retinopathy and blindness, and cardio- and cerebrovascular deaths. Mortality was higher than in nondiabetic dialysis patients.

Severe renal failure associated with proteinuria occurred in a 21-year patient, who had massive rheumatic aortic regurgitation. There was no sign of congestive heart failure or extra-cellular dehydration. Subacute bacterial endocarditis was ruled out by appropriate laboratory investigations. Prosthetic aortic valve replacement resulted in normalization of the renal function and marked reduction of proteinuria. Renal histology showed severe sclerotic endarteritis involving predominantly the large arteries, and membrano-proliferative-like glomerulopathy without immune deposits. The role of the massive aortic regurgitation in the production of renal failure and histologic alterations is suggested.

Acute renal failure following angiography with contrast agents is known to occur, but the circumstances and frequency of its occurrence are not well described. A retrospective review of consecutive angiographic procedures performed over a six month interval revealed a 12 per cent incidence of renal failure following angiography. The degree of failure was severe in approximately 30 per cent of these cases and was associated with a significant mortality even though renal function usually recovered. The occurrence of renal failure was associated with the presence of renal insufficiency, impaired liver function, diabetes mellitus, hypoalbuminemia and proteinuria at the time of angiography to a statistically significant level. Furthermore, combinations of these factors, particularly preexisting combined renal insufficiency and impaired liver function, were associated with an increased incidence of acute renal failure. It is concluded that angiography poses a significant hazard to patients with underlying medical problems, particularly those involving the excretory routes of the contrast agent.

We describe 11 patients whose renal biopsies showed minimal changes with focal segmental glomerulosclerosis. These patients, in contrast to the majority of patients with similar renal histology, went into renal failure within 2 1/2 years of clinical onset. All were young, severely nephrotic, most hypertensive, with microscopic hematuria, non-selective proteinuria and extreme hypercholesterolemia. Treatment with corticosteroids and cytotoxic drugs was without effect in any patient. Despite rapid decline in renal function, profuse proteinuria and a nephrotic syndrome persisted into terminal uremia and continued even after dialysis had begun. Seven patients were given nine allografts; four grafts failed because of immediate vascular complications, and a persistant nephrotic syndrome was evident in two of the five surviving grafts. This did not, however, lead to graft failure. Two patients died on dialysis because of myocardial problems. These patients with rapid decline in renal function constitute a distinct clinical subgroup amongst those with focal and segmental glomerulosclerosis; it is possible that they have a different primarily vascular pathogenesis in contrast to other patients with similar renal biopsy appearances.
