The term diabetic nephropathy includes the Kimmelstiel-Wilson intercapillary glumerulosclerosis (1936), arterio-arteriolosclerotic changes and pyelonephritis. In principle, diabetic nephropathy becomes more frequent with increasing duration of diabetes mellituus. Pyelonephritis is 4 to 5 times more frequent in diabetics than in the general population. Elderly overweight women are particularly at risk. - Only the nodular intercapillary glomerulosclerosis and not the diffuse or exudative form is specific for diabetes mellitus. It is found in 20-40% of all diabetics who have had the disease for 10-15 years. Whether the microangiopathy is typical of diabetes mellitus remains to be seen. Due to the intense cardiovascular changes, possible disorders of brain and liver function and infection, the prognosis of renal insufficiency is considerably worse in diabetics than in non-diabetics.

The following groups of patients are discussed. 1st group: 51 patients with diabetes mellitus and chronic pyelonephritis, 2nd group: 15 patients with diabetes, hyperuricaemia, adiposity and pyelonephritis. It was established that in the first group pyelonephritis was therapeutically well to be influenced by antiobiotics and chemotherapeutics after stopping of diabetes. In the second group the success was less satisfactory and it was also to be achieved retardedly on account of the massive renal lesion, by the combination of diabetes and uricopathy. The clinical syndrome of diabetes mellitus, hyperuricaemia and adiposity is discussed.

Diabetes mellitus is a prevalent disorder, well controlled in many persons with prolongation of life. Several radiologic manifestations are sufficiently specific to suggest a diagnosis in the unidentified patient, but even more important is an awareness of the sometimes life-threatening complications of diabetes which can be diagnosed from uroradiologic studies. We review the following urinary tract manifestations and complications of diabetes: pyelonephritis, perinephric abscess, renal papillary necrosis, emphysematous pyelonephritis, emphysematous cystitis, fungus infections, calcification of the vas deferens, seminal vesicle, and intrarenal branches of the renal artery, neuropathic bladder, and renal failure.

In the suggested classification of affections of the kidneys in diabetes mellitus the main attention is paid to the vascular genesis of the appearing disturbances. The terms used formerly ("diabetic glomerulosclerosis", "diabetic nephropathy") failed to reflect the primary affections of the vessels. The following new terms are suggested: "diabetic microangionephropathy" (affection of the small vessels), "macroangiography" (affection of the large vessels), "diabetic angionephropathy" (complex affection of the renal vessels). "Pyelonephritis" (acute and chronic) was also introduced into the classification due to its exceedingly frequent occurrence in diabetes. The term "diabetic nephropathy" is suggested for complex affection including diabetic angionephropathy and pyelonephritis. Diabetic microangionephropathy should be divided into four clinico-laboratory stages; their characteristics are presented. Particular attention was paid to the accessibility of their diagnosis in medical institutions.

Insulin antagonism characterizes infection, but the mechanism is unknown. Previous studies have been performed during the acute catabolic stage of infection, and the resultant metabolic changes reflect this decreased food intake and weight loss. To delineate metabolic alterations due to infection itself, rats with pyelonephritis induced by tail-vein injection of 1 ml. of Streptococcus faecalis (10(9) bacteria per milliliter) were studied two weeks later during a period of near-normal weight gain and food intake. Fasting growth hormone concentrations (nanograms per milliliter) in the pyelonephritic rats were nearly five times normal (45.8 vs. 9.9). Intra-arterial glucose and insulin tolerance tests were impaired. Early glucose-induced insulin release was depressed. Fat pads from infected rats manifested higher basal lipolysis per cell. Glycerol-mediated gluconeogenesis by liver slices was decreased. This pathway was unaffected by insulin in infected rats but readily inhibited in control rats. The following metabolic parameters were similar in control and infected animals: (in vivo) fasting concentrations of plasma glucose, free fatty acids, triglycerides, total corticoids, creatinine, insulin, glucagon, molar ratios of insulin and glucagon, glucose and insulin responses to tolbutamide, and glucagon and free fatty acid suppression after glucose; (in vitro) glucose metabolism by muscle and fat, epinephrine- and theophylline-stimulated lipolysis and re-esterification by epididymal fat pads, fasting hepatic glycogen content, glucose production by liver slices with and without alanine. No plasma insulin antagonist was found in the infected rats. Metabolic alterations in infected rats can be demonstrated independently of the associated catabolism. Increased growth hormone secretion cannot explain all of these changes.

We present a case of nephrotic syndrome complicating acute pyelonephritis in a 45-year-old man. His first attack of acute bacterial pyelonephritis had two unusual features: transient nephrotic syndrome and chronic recurrent episodes of papillary necrosis. The former, which lasted for two weeks, was characterized by edema, excretion of 7.7 g of urinary protein per 24 hours and hypoproteinemia (1.8 g per 100 ml). A percutaneous renal biopsy two weeks after the height of the nephrotic state showed normal glomeruli by light and electron microscopy and immunohistologic studies. Interstitial changes were noted. Over two years the patient has passed approximately 50 fragments, characterized as necrotic tissue containing tubular structures. He has no evidence of diabetes mellitus, urinary-tract obstruction or ureteral reflux, analgesic abuse or atypical vasculitis. He is afebrile but has recurrent bacteriuria despite antibiotics. This case demonstrates that acute pyelonephritis must be added to the list of diseases causing the nephrotic state.

The parathyroid glands of 14 deceased diabetics were investigated as well as nine control non-diabetics. Various in character and degree histological alterations were observed during the morphological investigations of those glands: mild or better manifested hyperplastic alterations (six cases), microadenoma (one case), focal vasculary determined atrophia (two cases, total atrophia of involutive type (two cases), close to the control alterations (three cases). Hyperplastic alterations are established most frequently in the presence of diabetic nephropathia and azotemia. They could be explained with the development of a secondary hyperparathyroidism, associated with chronic renal insufficiency. In single cases, an effect of the disturbance of the calcium-phosphorus metabolism in diabetes is admitted. Changes in the parathyroid glands, from the type of generalized diabetic microangiopathy, is suspected in one of the deceased patients. Two microadenomas were found in another case, predominantly with dark basic cells. No dependence was established between the morphological alterations and the severity, diabetes form, nor with the presence of pyelonephritis. Certain dependence was established between the age of the deceased and the stage of the azotemia.

In a number of 3,554 clinically manifest diabetics who were admitted for the treatment of metabolism or other diseases from 1967 to 1974 12.1 per cent of hepatopathies were found. In men the incidence was 15.2 per cent, in women 10.7 per cent. Among these the fatty degeneration of the liver (28.8 per cent) and the cirrhosis (17.4 per cent) were most frequent. Referred to the entirety the result was an incidence of cirrhosis of 2.1 per cent. The confirmation of the diagnosis is performed by biopsy and endoscopy in 92 per cent. In 60 per cent of the examined persons the diagnosis was unknown before admission. There was no correlation to the duration of the diabetes. In the number of patients there appeared above all persons older than 50 to 60 years. The following concomitant diseases occurred: hypertension (33 per cent), coronary diseases (32 per cent), pyelonephritis (17 per cent) and adiposity (13 per cent).

A clinical and roentgenographic analysis of 13 patients with pathologically proved xanthogranulomatous pyelonephritis (X-P) has demonstrated that many previously accepted truisms associated with this disease may not be valid. As a result of this study it is suggested that X-P: 1. Does have a prominant female distribution. 2. May arise relatively acutely. 3. Can be associated with a well-functioning kidney. 4. May destroy the kidney and collecting system. 5. Does not demonstrate neovascularity. 6. Can be distinguished angiographically from hypernephroma. 7. May be associated with diabetes. Other important facts were again observed: 1. X-P is still often associated with staghorn calculi and urinary tract obstruction. 2. Proteus mirabilis is the main offending organism.

Given the high morbi-mortality of foot infections among the diabetics and the poor knowledge of their predictive, clinical and evolutive factors, we have retrospectively studied a group of patients with these characteristics, comparing them with infections among diabetics affecting other locations. We studied 66 infections among diabetics: 34 patients with diabetic's foot and 32 with infections at other locations: 20 pyelonephritis and 12 pneumonias. Medical records were obtained in all cases and all patients underwent a complete physical exploration in order to assess their risk factors. We observed as a significant predictive factor of diabetic's foot, diabetes type I, with an evolution longer than 10 years, neuropathy, vasculopathy or retinopathy. From the clinical point of view and compared with the other infections, these patients showed longer hospitalization, greater initial clinical severity, glucemias higher than 200 mgr/l., anemia and high GSR. Ethiologically, the infection of diabetic's foot was polymicrobian in 42.3% of all cases, being S. aureus the microorganism more frequently isolated. On the contrary, in infections at other locations, monomicrobian flora was more frequent, being E. coli the most frequent in pyelonephritis and S. pneumoniae in pneumonias. The evolution was satisfactory in all cases, with a close medical and surgical combined treatment and the appropriate use of antibiotic combinations, mainly clindamicine + tobramicine in the diabetic's foot and cefuroxime in the other locations.
