Diabetic donors are still reluctantly accepted as potential organ donors because of supposed poor graft function caused by diabetic lesions. The results of transplantation of six kidneys from three donors with insulin dependent diabetes mellitus are reported. All three donors had a normal creatinine clearance and absence of proteinuria. Renal biopsies were taken. Five grafts are still functioning, six months to two years after transplantation with a mean creatinine clearance of 69ml/min (range 51-95). Three of five biopsies taken six months after transplantation showed marked decrease of the diabetic lesions. On the basis of these findings it seems justified to accept kidneys from diabetic donors for transplantation.

The urinary excretion of beta2-microglobulin, albumin, kappa light chains, transferrin, and IgG as well as their concentration ratios were assessed in 27 nondiabetic patients with proteinuria and in 72 IDDM patients, 41 with proliferative retinopathy (PR) and 31 without retinopathy, matched for age, duration of diabetes, and treatment. The mean excretions of albumin, transferrin, and IgG were similar in patients with nondiabetic proteinuria and in IDDM patients with PR and were significantly higher than in IDDM patients without retinopathy. Despite similar albumin excretion, the amount of excreted kappa light chains was significantly higher in IDDM patients than in patients with nondiabetic proteinuria, resulting in an elevated kappa chain/albumin ratio. Furthermore, diabetic subjects without microalbuminuria showed increased kappa chain/albumin ratio, indicating that increased urinary excretion of kappa chains may be an early sign of diabetic nephropathy. Determination of kappa light chain excretion may have clinical implications in the differentiation between proteinuria of diabetic and nondiabetic origin. The ratio kappa chain/albumin was independent of the excretion of beta2-microglobulin in patients with PR, suggesting that the reduced ability to reabsorb immunoglobulin light chains may occur earlier than that of beta2-microglobulin in the development of tubular dysfunction in insulin-dependent diabetes mellitus.

To evaluate the role of renal haemodynamic factors in the pathophysiology of diabetic nephropathy, we determined by radionuclear techniques glomerular filtration rate (GFR) and renal plasma flow (RPF) in 18 patients affected by insulin dependent diabetes mellitus (IDDM) in good metabolic control, with normal blood pressure and plasma creatinine. GFR and RPF measured in the same patients after ten months correlated with proteinuria and duration of diabetes. Our finding of a significant correlation between the decline of RPF and duration of diabetes may support the haemodynamic hypothesis of progression of diabetic nephropathy.

Eighteen individuals with IDDM (type I) and diabetic nephropathy in whom the initial glomerular filtration rate (GFR) was reduced but not below 60 ml/min per 1.73 m2 were observed for an average of 3 yr. The rate of further decline of GFR was found to range between -2 and 21 ml/min/yr. The duration of diabetes until the GFR was first found to be reduced varied between 14 and 33 yr and was not correlated to the ensuing rate of decline in GFR (r = -0.13). In 10 individuals who developed uremia 40 yr or more after onset of IDDM, the development of persistent proteinuria was followed by hypertension and increased serum creatinine 2 yr later and by terminal uremia after an average of 8 yr. This is also the normal time span for individuals who develop terminal uremia after shorter duration of diabetes. We conclude that the course of clinical diabetic nephropathy is not more favorable in individuals with late onset of this complication and that there is no point at which a person with diabetes can be considered to be spared from developing diabetic nephropathy.

Two kidneys were removed from a cadaveric donor with 17-year history of type 1 diabetes. At the time of death the donor had proteinuria but normal serum creatinine, and on histological examination the kidneys showed features of established diabetic nephropathy including diffuse glomerulosclerosis and thickening of mesangial matrix and capillary basement membranes. After transplantation into non-diabetic recipients (cold ischaemia times 46 h and 52 h) the kidneys functioned well with standard immunosuppression. Renal biopsy specimens taken 7 months after transplantation showed almost complete resolution of the nephropathy and both patients remain free from proteinuria after a further 7 months. As well as indicating that longstanding type 1 diabetes need not always contraindicate kidney donation, these observations are relevant to the pathogenesis and management of diabetic nephropathy.

Forty-seven patients with insulin-dependent diabetes (IDDM) and diabetic nephropathy and 47 controls with IDDM without diabetic nephropathy were interviewed about their previous and current smoking habits. The patients in the two groups were matched according to sex, age, age at onset, and duration of diabetes. All patients in the nephropathy group had proteinuria and decreased glomerular filtration. None in the control group had ever had proteinuria as tested by dip stick. The total amount of smoking until date of interview was estimated for each individual and presented as an index. The patients with nephropathy had a significantly higher smoking index than the controls. In the nephropathy group there were also more numerous current smokers, more heavy smokers and fewer individuals who had never smoked than in the control group. The link between diabetic renal microangiopathy and smoking may be through mechanisms such as increased platelet aggregation, accentuated tissue hypoxia and hemodynamic or metabolic effects of repeated noradrenaline release.

We describe a 25-year-old male with juvenile onset diabetes mellitus who developed severe pseudomembranous enterocolitis with intractable diarrhea for which he was maintained on total parenteral nutrition. Subsequently, he developed clinical signs and typical radiological manifestations of hypertrophic osteoarthropathy (HOA) associated with hemolytic anemia, proteinuria and immunoglobulin deficiency. Immune complexes were not detected in either sera and synovial fluid.

We determined whether the serum lipoprotein levels in insulin-dependent diabetic patients (IDDM) with nephropathy and in patients on haemodialysis or continuous ambulatory peritoneal dialysis were affected by beta-blocker therapy. A case control study was performed in 18 IDDM patients with diabetic nephropathy, in 18 patients receiving chronic haemodialysis (HD) and 16 patients undergoing continuous ambulatory peritoneal dialysis (CAPD). In IDDM patients with diabetic nephropathy very low density lipoprotein-cholesterol (VLDL-CHOL) (0.680 +/- 0.17 vs 0.197 +/- 0.04 mmol/l, p = 0.004), total triglycerides (1.71 +/- 0.23 vs 0.808 +/- 0.14 mmol/l, p = 0.004) and very low density lipoprotein triglyceride (VLD-TG) were higher in the beta-blocker therapy group. In haemodialysis patients, beta-blocker therapy caused no significant changes in the serum lipoprotein profiles compared to the control group. In patients receiving continuous ambulatory peritoneal dialysis VLDL-CHOL was significantly higher (1.47 +/- 0.24 vs 1.08 +/- 0.21 mmol/l, p = 0.042) and cholesterol-high density lipoprotein (HDL-CHOL) was lower in the beta-blocker therapy group. The elevated VLDL-CHOL level (0.96 +/- 0.12 vs 1.24 +/- 0.14 mmol/l, p = 0.021) was correlated with the duration of CAPD in patients receiving beta-blocker therapy. Antihypertensive therapy with beta-blockers in IDDM patients with persistent proteinuria and in patients on continuous ambulatory peritoneal dialysis appears to adversely effect serum lipoproteins which may add to their cardiovascular risk.

The excess risk of cardiovascular disease in Type 1 diabetes mellitus compared to non diabetic subjects is only partially explained by standard risk factors. Several studies suggest that Lp(a) concentrations are increased in Type 1 diabetes mellitus, but data are still controversial. Moreover, a high cardiovascular risk has been reported in diabetic patients with persistent proteinuria. Therefore, the aim of this study was to compare the Lp(a) particle levels in insulin-dependent diabetic patients with or without increased urinary albumin excretion. Cross-sectional study of Lp(a) plasma levels in a population of 140 insulin-dependent diabetic patients: 83 without increased proteinuria, 14 with borderline elevation of urinary albumin excretion, 27 with micro- and 16 with macro-proteinuria. Simultaneous determination of plasma lipids, fasting blood glucose and HbA1c was performed. The mean plasma Lp(a) concentrations and the distribution of the levels were comparable in all of the diabetic patient groups. No relationship existed between Lp(a) and HbA1c, fasting blood glucose or any lipid plasma levels. No influence of albumin excretion rate on Lp(a) levels was observed. These data provide no evidence of a specific contribution of Lp(a) particles to the increased morbidity and mortality from cardiovascular disease observed among patients with nephropathy.

An endogenous sodium pump inhibitor, or digitalis-like factor (DLF), has been postulated to mediate essential hypertension. It may also play a role in preeclampsia. However, studies of this factor in hypertensive pregnancy have not provided consistent findings. Part of this may be due to the absence of subclassification of pregnant women with pregnancy-induced hypertension (PIH) when assessing these parameters. In this study we explored serum DLF and digoxin-like immunoreactive factor (DLIF) in insulin-dependent diabetic (IDDM) women with normotensive pregnancies or PIH, comparing them to each other and to nondiabetic pregnant women. Our results demonstrated that nondiabetic women with preeclampsia (PE, PIH with proteinuria) had significantly increased serum DLF and DLIF compared to normotensive pregnant women (NL BP). Women with transient hypertension of pregnancy (THP, PIH without proteinuria) had intermediate values (DLF. NL BP: 3.3 +/- 0.6, THP: 4.8 +/- 1.1, PE: 7.6 +/- 1.3% inhibition [Na,K]-ATPase, P < .05 ANOVA; DLIF. NL BP: 0.22 +/- 0.02, THP: 0.28 +/- 0.03, PE: 0.35 +/- 0.02 ng digoxin equivalents/mL, P < .05 ANOVA). Pregnant normotensive IDDM women had significantly higher serum DLF and DLIF activity than their nondiabetic counterparts (DLF. non-IDDM NL BP: 3.3 +/- 0.6 v IDDM NL BP: 8.8 +/- 1.2% inhibition [Na,K]-ATPase, P = .0008; DLIF. non-IDDM NL BP: 0.22 +/- 0.02 v IDDM NL BP: 0.31 +/- 0.02 ng digoxin equivalents/mL, P = .005).(ABSTRACT TRUNCATED AT 250 WORDS)
