In the plasma of healthy subjects, 4 fractions of immunoreactive glucagon are found. The first has a molecular weight of about 160000, the second of 9000, the third 3500 and the fourth about 2000. The third probably corresponds to the intact hormone glucagon. In cirrhosis of the liver and diabetes mellitus, a statistically significant rise in the third fraction has been found. In patients with tumors of the pancreatic A-cells, in addition to the third fraction the second in particular was also increased: it may be a precursor of the glucagon molecule. In chronic renal insufficiency, fractions 2 and 3 were as markedly increased as in glucagonoma, which suggests a role for the kidney in the decomposition of glucagon. The pathophysiologic significance of the four immunoreactive fractions of glucagon cannot yet be assessed with certainty.

Thirty-two patients with advanced chronic renal insufficiency due to juvenile onset diabetes mellitus were submitted to dialytic treatment, 16 with intermittent haemodialysis and 16 with peritoneal dialysis. Both groups were similar with respect to onset of diabetes, course of renal insufficiency, as well as start and duration of dialysis treatment (382 and 389 patient months respectively). Patients on haemodialysis showed a more rapid progress of retinopathy and neuropathy, whereas the control of hypertension proved to be more difficult with peritoneal dialysis. A reduced peritoneal dialysance of urea, demonstrated in patients with diabetic nephropathy, could be improved by dipyridamole administration, whereas this drug showed no effect on the dialysances of urea and inulin in patients with chronic renal insufficiency of non-diabetic origin. There were no differences between the survival rates of the two groups which were substantially lower than in non-diabetic dialysis patients.

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.

During a 4-year period, acute renal failure was observed in 27 patients (mean age 65 years) treated by various angiotensin-converting-enzyme (ACE) inhibitors for hypertension, heart failure, or a combination of both. None had significant renal artery stenosis on angiography. Overt volume depletion was present in 21 and hypotension in 12 cases. All patients received diuretic therapy and/or a low-salt diet. Other facilitating factors included cardiac failure, pre-existing chronic renal insufficiency, combined therapy with non-steroidal anti-inflammatory drugs, and diabetes mellitus. Twenty-two patients had two or more of these factors at presentation. A renal biopsy performed in 10 cases showed severe arteriosclerosis of small renal arteries in eight and acute tubular necrosis in five instances. Therapy comprised volume expansion, and withdrawal of diuretics and, except in two patients, of ACE inhibitors. Twenty-one patients recovered normal renal function, two died, and permanent renal damage remained in four. These results suggest that sodium depletion has a critical role in inducing acute renal failure, whose outcome is not always benign. A combination of diuretics and ACE inhibitors should be prescribed with caution, especially in older patients with small as well as with large renal vessel disease.

A high incidence of renal lesions is observed in patients with insulin-dependent diabetes. In the early stages of the disease glomerular capillary hemodynamics is altered with, in particular, glomerular hyperfiltration related to several factors: enhanced glomerular capillary flow rate, capillary hypertension and increased filtration area. These hemodynamic changes could affect development of the glomerular microangiopathy: the final outcome of this is the glomerulosclerosis associated with a progressively worsening and ineluctable chronic renal insufficiency. Hypertension, frequent in the early stages, is practically constant when the neuropathy stage has been reached; it is well established that hypertension accelerates the development of glomerular lesions and the progression of the renal impairment. Experimental and clinical studies have clearly demonstrated that antihypertensive treatment slows down the degradation of renal function. All antihypertensive drugs appear to be effective, but converting enzyme inhibitors, by their effects on renal hemodynamics, could play a particular role in the prophylactic treatment of diabetic nephropathy. Determination of urinary excretion of albumin (microalbuminuria), the global evidence of the onset of a nephropathy is useful for the follow up of the renal disease, allows follow up of the renal lesion and evaluation of the efficacy of treatment.

Frequency of gout in French Polynesia has induced us to define a type of "hyperuricemia Polynesian" from a population of patients admitted in a general Medicine Ward. Each admitted patient gets immediately a blood check-up. A figure higher than 70 mg/l in male and 60 mg/l in female is considered as pathological. In such a case, uricemia and uraturia are tested every 24 h for three days and we consider the mean value of these three tests. On the other side, some admitted patients non-hyperuricemic, are examined according to the same protocol. So, we have two groups: 31 hyperuricemics and 20 non-hyperuricemics, secondarily grouped according to age, sex, ethnic. We did not consider some secondary causes of hyperuricemia (chronic renal insufficiency diuretic treatment, psoriasis etc.). 1. Within the hyperuricemic population, mean uricemia is 85.35 mg/l versus 52.65 mg/l in the second sample. In the hyperuricemic group (21 males and 10 females) 48% are gouty and 13% of them are females. Articular manifestations are acute arthritis, affecting mainly inferior limbs, ankles, knees). We did not notice any significant divergence between uricemia and uraturia of gouty and non gouty people. Within the group of gouty people, percentage of individual hyper excretion is 53% (uraturia greater than 600 mg/24 h) with no significant divergence with the non-gouty group: Nephrolithiasis is rare (3%). There is no significant divergence between urinary pH of gouty and non-gouty people. Associated metabolic troubles are: diabetes (26%) high triglyceridemia (43%) three syndromes associated together (hyperuricemia + diabetes + hypertriglyceridemia) in 19.5%, total cholesterol is normal (2.07 g/l) but a low cholesterol (0.30 g/l).(ABSTRACT TRUNCATED AT 250 WORDS)

Indices of thrombocytic hemostasis were determined in 40 patients with diabetic glomerulosclerosis. It was found that patients suffering of diabetic glomerulosclerosis with chronic renal insufficiency showed signs of hypercoagulemia while changes of the thrombocytic hemostasis become of diverse values. There was a high correlation of hemostasis changes and clinical manifestations of diabetes mellitus and diabetic glomerulosclerosis. Three tests are recommended for treatment choice: hemolysate-aggregation test, determination of soluble complexes of monomer fibrin and fibrin-splitting product.

Diabetic nephropathy is the most frequent cause of chronic renal insufficiency in adults. Its early stage, characterized by increased albuminuria, develops in susceptible subjects already manifestation of diabetes. This stage can be treated by inhibitors of the angiotensin-converting enzyme which reduce the pathologically elevated intraglomerular pressure even in normotonic subjects. Enalapril was administered for a period of 12 weeks to eight children and adolescents with a normal blood pressure and albuminuria of 30-300 mg/24 hours during repeated assessments. During treatment there was not only a significant decline of albuminuria (from 104.6 +/- 42.7 mg/24 hours to 47.2 +/- 15.4, p = 0.003) but also a drop of the pathological glomerular hyperfiltration (from 3.38 +/- 1.87 ml/s to 1.48 +/- 0.54 ml/s within six weeks - p = 0.02 and to 2.05 +/- 0.80 ml/s resp. within 12 weeks, n.s.). The favourable effect persisted also for some time after discontinuation of treatment. Treatment was relatively well tolerated by the patients. The problem remains whether it is possible to retard or prevent in this way the development of further stages of diabetic nephropathy, include chronic renal failure.

Forty-eight patients with acute renal failure (ARF) who were referred to the Department of Renal Medicine, Singapore General Hospital for acute dialysis between August 1985 and August 1989 were studied retrospectively to identify risk factors associated with ARF that serve as prognostic indicators. There was no difference in the mean age of survivors and non-survivors (49.5 +/- 17.5 years vs 53.5 +/- 18 years, p greater than 0.05). The overall mortality rate was 52%. ARF as a result of surgical complication had a higher mortality rate in comparison to ARF from medical complications (66% vs 50%, p greater than 0.05). Septicaemia was the most common cause of ARF requiring dialysis. Hepatobiliary sepsis was the most frequent cause of septicaemia. Pre-dialysis serum urea and creatinine levels, and the number of dialysis treatments did not affect the outcome. Poor prognostic indicators included oliguria or anuria, fluid overload and coma. Patients tended to have a worse outcome if they had more than three risk factors taken from the following list:-decreased renal perfusion, assisted ventilation, coma, gastrointestinal dysfunction, recent surgery, sepsis, congestive heart failure, hepatobiliary dysfunction, malignancy, diabetes mellitus, chronic renal insufficiency and poor nutritional status. Early referral of patients with septicaemia due in particular to hepatobiliary infection may improve the prognosis.

End-stage renal disease is a major cause of morbidity and mortality in the U.S. population and a significant contributor to national health-care expenditures. In recent years, a growing body of literature has accumulated from studies in animals and humans to suggest that dietary protein restriction can significantly retard the progression of chronic renal insufficiency. This article reviews the relevant literature and outlines the questions that remain for future investigation.
