Making use of immunoelectrophoretic method for semiquantitative determination, the fibrin/fibrinogen degradation products (FDP) were determined in urine and blood serum of 63 patients with diabetes mellitus with various vascular-degenerative and inflammatory complications in the kidneys as well as of 23 clinically healthy subjects. FDP presence in urine was found mainly in patients with diabetic nephropathy (in 32.6%). FDP in blood serum was found with significantly increased values in diabetic nephropathies (mean 14.9 mg/ml) and particularly in their advanced forms (mean 16.4 mg/ml), whereas in diabetics with chronic pyelonephritis, their content was increased in single cases (mean 1.9 mg/ml). A moderately manifested correlation of FDP in urine and serum with blood urea, serum creatinine and creatinine clearance was established as well as partly with protein quantity in urine and diastolic arterial pressure. The determination of FDP in urine and blood serum could serve as an additional sign in the differentiation of diabetic nephropathy and chronic pyelonephritis in diabetic patients.

Factors associated with an excessive rate of dialysis induced symptomatic hypotension (SH) were analysed in a population of 1110 patients treated by chronic haemodialysis in 32 French dialysis centres. Significant risk factors for SH were female sex, diabetic nephropathy as the primary renal disease, two weekly dialysis schedule instead of three, use of Coil type dialysers instead of parallel-flow or hollow-fibre dialysers, low dialysate osmolarity, low dialysate K, high body weight subtraction during sessions, low predialysis plasma proteins, high predialysis blood urea, and low nerve conduction velocity. On a statistical basis, the results show the predominance of volume depletion over dialysate composition or neuropathy.

Hematuria is not described as a common finding in diabetic nephropathy, and may suggest nondiabetic renal disease. We reviewed the records of 59 children and adolescents with insulin-dependent diabetes mellitus referred to the Children's Kidney Center from 1983 to 1992. Fifty-two patients had clinical and/or biopsy evidence of diabetic nephropathy; 18/52 (35%) had microscopic hematuria at the time of referral. Patients with hematuria on presentation were referred for: hypertension (61%), proteinuria (61%), and decreased glomerular filtration rate (GFR) (11%). For patients without hematuria on presentation, reasons for referral included hypertension (79%), proteinuria (56%), and decreased GFR (3%). When comparing patients with and without hematuria, those with hematuria had a significantly longer duration of diabetes (12.8 +/- 3.1 versus 10.8 +/- 3.7 years, p < 0.05). The groups did not differ significantly with regard to age (18.3 +/- 1.8 versus 17.1 +/- 2.9 years), height (162.2 +/- 10.4 versus 159.3 +/- 11.3 cm), weight (63.9 +/- 10.9 versus 59.4 +/- 14.8 kg), systolic blood pressure (137.2 +/- 11.9 versus 133.2 +/- 13.2 mm Hg), diastolic blood pressure (85.6 +/- 7.6 versus 83.9 +/- 13.4 mm Hg), serum creatinine (1.0 +/- 0.18 versus 1.0 +/- 0.43 mg/dL), blood urea nitrogen (15 +/- 5 versus 13 +/- 4 mg/dL), glomerular filtration rate (117 +/- 34 versus 117 +/- 46 mL/min/1.73 m2), 24-h urine protein (2311 +/- 3862 versus 570 +/- 476 mg/day), or microalbuminuria (75 +/- 41 versus 34 +/- 35 micrograms/min). We detected a significant association between retinopathy and microscopic hematuria (sensitivity 47%, specificity 82%, p < 0.05), but no association between labstix proteinuria or sex and hematuria.(ABSTRACT TRUNCATED AT 250 WORDS)

The effects of high doses of hemodialysis on the nutritional status, morbidity and mortality of 85 metabolically stable chronic hemodialysis patients were studied. Urea kinetic studies showed Kt/Vurea 1.8 +/- 0.4, mean time-average concentration of urea (TAC) 48.4 +/- 11 mg/dL and protein catabolic rate (PCR) 1.3 +/- 0.3 g/kg/d. All patients were followed up over a 12-month period with blood biochemistry and anthropometry measurements. The total number of hospitalizations and mortality were also recorded. Study results showed positive correlations between PCR and Kt/V, and PCR and TAC. Age was negatively correlated with serum albumin. A PCR < 1.0 g/kg/d (n = 14) was highly associated with more hospital admissions than those with a PCR > or = 1.0 g/kg/d (n = 71). There was no significant difference in biochemical nutritional indices and urea kinetic study between diabetic patients and non-diabetic patients, while aged patients (> or = 65 years) had significant lower serum albumin and hematocrit. A significant number of patients had anthropometric measurements below the 10th percentile, when compared with the standard for the Taiwan area. No difference was found in the effect of diabetes mellitus and time on hemodialysis on the anthropometric variables. The mortality rate was 4.7% (4/85), and all deaths involved patients over 65 years of age with either diabetic nephropathy or diffuse vascular disease. Despite high doses of dialysis, there was a high prevalence of subclinical malnutrition evidenced by anthropometric measurements. However, high doses of dialysis improved protein intake, nutritional status, as well as morbidity and mortality. Younger patients (< 65 years) had excellent results in this short-term study.

The reactive vascular-injuring amino acid homocysteine was previously shown to be increased in plasma in diabetic patients with clinical signs of nephropathy. In this study, plasma homocysteine was measured in type 1 diabetic patients with normoalbuminuria (n = 22), microalbuminuria (n = 40) and proteinuria (n = 14) in order to investigate whether plasma homocysteine levels are increased already at the stage of incipient nephropathy, i.e. microalbuminuria. Furthermore, patients were characterized according to the degree of retinopathy. Plasma homocysteine in the whole population (n = 76) was related to B-Folate (r = 0.38, p < 0.01), S-Creatinine (r = 0.55, p < 0.001), S-Urea (r = 0.37, p < 0.01), U-Albumin (r = 0.46, p < 0.001), urinary N-acetyl-beta- glucosaminidase (r = 0.40, p < 0.001), systolic blood pressure (r = 0.36, p < 0.01) and diabetes duration (r = 0.44, p < 0.001). There were no differences in plasma homocysteine levels between patients with normoalbuminuria (8.0 +/- 1.7 mumol l-1; mean +/- SD) and those with microalbuminuria (9.1 +/- 3.4 mumol l-1). However, patients with clinical signs of nephropathy had higher plasma homocysteine levels (12.9 +/- 5.7 mumol l-1, p < 0.01) compared to the other two groups. There was no association between plasma homocysteine levels and different degrees of retinopathy. Thus, the present study does not show any relation between plasma homocysteine levels and early stages of diabetic nephropathy or retinopathy indicating that elevated concentrations of plasma homocysteine does not explain the increased risk for atherosclerosis observed in patients with microalbuminuria.

Results of the Diabetes Control and Complications Trial indicate that intensive insulin treatment of patients with type I diabetes would greatly reduce the incidence of diabetic nephropathy. Another multicenter trial indicates that modest protein restriction is of no value in children with chronic renal failure. The relationship between urea nitrogen excretion and total nitrogen excretion in children differs from that in adults. A repeated crossover study found that ketoacids slow progression of renal failure, in comparison with amino acid supplements to the same diet. Long-term protein restriction does not lead to protein deficiency at the onset of dialysis. When combined with essential amino acid supplements, a low-protein diet may gradually correct hypoalbuminemia in nephrotic subjects.

In adult female rats diabetic nephropathy was induced by i.v. administration of streptozotocin (6 mg/100 g b.w.). The animals survive for 3 weeks when very low daily doses of insulin (0.3 IU/animal) are administered. High blood urea concentrations and distinct proteinuria indicate the impairment of kidney function in streptozotocin diabetic rats. Streptozotocin induces mild polyuria and increased renal excretion of potassium; there is also an increase in renal excretion of administered p-aminohippurate. Three weeks after administration of streptozotocin the formation of lipid peroxides is increased in the kidney. At this time glutathione content (GSH, GSSG) is unchanged in liver and kidney of streptozotocin diabetic rats. Impairment of kidney function in streptozotocin diabetic rats can be prevented by daily supplementation with sufficient doses of insulin (about 3 IU/animal).

To assess whether moderate dietary protein restriction can delay the progression of overt diabetic nephropathy, 22 subjects with insulin-dependent diabetes mellitus were randomly assigned to an unrestricted protein diet (> 1.6 g.kg body wt-1.d-1) or a moderately protein-restricted diet (0.8 g.kg body wt-1.d-1) and followed prospectively for six mo. Direct isotope methods were used to assess renal function. Protein intake was assessed by measurement of urinary urea nitrogen. The two groups were well-matched for age, sex, duration of diabetes, glycemic control, blood pressure, and degree of renal insufficiency. Patients consuming the unrestricted protein diet (n = 11) showed a progressive decline in glomerular filtration rate of 1.3 mL.min-1.mo-1 with no change in proteinuria. Patients consuming the moderately protein-restricted diet showed a marked decrease in the degree of proteinuria (2.15-1.13 g/d, P = 0.036) and a stabilization of glomerular filtration rate. This occurred independently of changes in blood pressure or glycemic control. Moderate dietary protein restriction can ameliorate progression of overt diabetic nephropathy.

According to a national survey of dialysis patients in Japan conducted by the Japanese Society for Dialysis Therapy, there were 1,033 patients on dialysis in the Shiga area which has a population of about 1.2 million. Of these 1,033 dialysis patients 140 were the result of diabetic nephropathy. From four hospitals affiliated to Shiga University of Medical Science the medical records of 90 diabetic subjects on dialysis therapy were reviewed and various clinical parameters were analysed and compared with those of patients with chronic glomerulonephritis. Since only one patient had Type 1 (insulin-dependent) diabetes, the remaining 89 with Type 2 (non-insulin-dependent) diabetes were used for this study. The significantly different variables between patients with Type 2 diabetes and chronic glomerulonephritis were age (60.4 vs 54.6 years, p < 0.05), BMI (22.4 vs 20.6 kg/m2, p < 0.001), cardiothoracic ratio (56.4 vs 53.3%, p < 0.001), mean blood pressure (110 vs 117 mmHg, p < 0.05), serum creatinine (9.0 vs 11.5 mg/dl, p < 0.001), serum urea-N (98.2 vs 115.5 mg/dl, p < 0.001), serum total protein (6.0 vs 6.5 g/dl, p < 0.001) and serum albumin (3.5 vs. 3.9 g/dl, p < 0.001). Serum levels of cholesterol and triglyceride were not significantly different between two groups, though the prevalence of electrocardiogram abnormalities, oedema, neuropathy, myocardial infarction and cerebrovascular diseases was significantly higher in the Type 2 diabetic group. These results suggested that Type 2 diabetic patients with end-stage renal disease were older, more malnourished, fluid overloaded and multi-morbid as a result of vasculopathy and neuropathy.(ABSTRACT TRUNCATED AT 250 WORDS)

Senile Nagoya, Shibata, Yasuda (NSY) mice developed amyloidosis and died from renal failure as a result of amyloidosis. NSY mice were first reported as experimental congenital diabetic mice by Shibata et al. in 1980. This study questioned whether NSY mice died from diabetic nephropathy. The authors of the present study investigated the life span and cause of death in these mice. The life span of NSY mice was found to be 618.7 +/- 72.5 days. NSY mice that lived for more than 400 days showed rising blood urea nitrogen and large amounts of amyloid deposits in the glomerulus of the kidneys. NSY mice died of renal amyloidosis. Immunological methods revealed that AApoAII was evident in the amyloid deposits of NSY mice. Apart from the kidneys, amyloid deposition was also found in the tongue, esophagus, stomach, small intestine, large intestine, rectum, lung, heart and adrenal glands. Amyloid deposits were found to a slight degree in the liver and the spleen. The most dominant amyloid deposition in NSY mice was seen in the glomerulus of the kidneys. From the point of view of amyloid depositional distribution, NSY mice were unique compared with other spontaneous amyloid mice.
