Out of 27 patients with advanced diabetic nephropathy accepted for renal transplantation. 11 had cardiac symptoms and 10 others had advanced neuropathy. The former group had a poor outcome with 100% mortality within one year, seven patients dying before transplantation. Neuropathy also indicated a poor prognosis. Early transplantation, before the stage of terminal uraemia, was at no advantage in this material.

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.

Twelve diabetics with terminal renal failure were maintained on chronic peritoneal dialysis (PD) for 2-28 months (average 10 months). 7/12 survived more than 1 year. Blood glucose levels were well controlled by the use of supplemental, intradialysis, intraperitoneal insulin. The incidence of dialysis-related complications, including peritonitis was not significantly higher than in controls. Neurophysiological studies revealed a high incidence of neuropathy initially with progression in most patients. Radiological studies revealed initial vascular calcifications in 7 out of 12 patients with progression in 4. Retinopathy did not progress significantly. PD is a suitable alternative to hemodialysis in the management of end-stage diabetic nephropathy.

Postural changes in plasma renin activity were studied in three groups of age and duration-matched male diabetics (potent, impotent and with postural hypotension) and in non-diabetic control subjects. Those diabetic subjects with postural hypotension due to automatic neuropathy had no increase in plasma renin activity to the erect posture whereas both the potent and impotent groups had similar plasma renin activity responses to the control subjects. There was a significant inverse correlation between the rise in plasma renin activity on standing and the postural drop in blood pressure (r = 0.476, P less than 0.01) but no correlation with other tests of autonomic reflex function such as the Valsalva manoeuvre and blood pressure response to sustained handgrip. The results suggested that the lesion responsible for the postural hypotension is in the efferent sympathetic pathway. However, neuropathy per se did not wholly explain the decreased postural plasma renin activity response. Diabetic nephropathy, with involvement of cells of juxtaglomerular apparatus, may also be implicated.

To examine the impact of metabolic control on renal responses to human atrial natriuretic peptide (hANP) in type 1 diabetes mellitus, 13 patients with HbA1 less than 8.5%, nine patients with HbA1 greater than 8.5% and ten healthy volunteers were studied. According to a randomized, single-blind trial design, 0.5 and 2.0 micrograms/kg hANP-(95-126) (Urodilatin) (Bissendorf Peptide, Hannover) or placebo were given as iv bolus injections at 90-minute intervals. Patients with HbA1 greater than 8.5% differed from those with HbA1 less than 8.5% in longer diabetes duration, more prevalent retinopathy and neuropathy and increased somatomedin C levels and urinary albumin excretion (p less than 0.05). In response to hANP, patients with HbA1 greater than 8.5% had decreased responses of urinary volume and sodium excretion in comparison to patients with HbA1 less than 8.5% (p less than 0.05) in whom renal responses to hANP did not differ from controls. Despite similar hANP levels, hANP-stimulated urinary cGMP excretion in patients was higher than in controls (p less than 0.01). Impaired renal responses to hANP in diabetes patients with insufficient glycemic control apparently contribute to the mechanisms of diabetic sodium retention. Near-normoglycemia may prevent this phenomenon which is intimately involved into the pathogenesis of diabetic nephropathy.

The association between diurnal blood pressure variation and diabetic nephropathy was assessed in four groups of Type 1 (insulin-dependent) diabetic patients who underwent 24-h ambulatory blood pressure monitoring using an oscillometric technique. Patients with nephropathy, who had never been treated for hypertension (group D3, n = 13), were individually matched for age, sex and diabetes duration to a group of microalbuminuric patients (D2, n = 26), to normoalbuminuric patients (D1, n = 26) and to healthy control subjects (C, n = 26). Group D3 was also compared to patients with advanced nephropathy receiving treatment for hypertension, mainly a combination of angiotensin converting enzyme inhibitors, metoprolol and diuretics (D4, n = 11). In group D3 24-h diastolic blood pressure (85 +/- 8 mm Hg) was comparable to the results obtained in D4 (85 +/- 8 mm Hg) but significantly higher than in D2 (78 +/- 7 mm Hg), D1 (73 +/- 7 mm Hg) and C (73 +/- 7 mm Hg, p < 0.05, Tukey's test). The night/day ratio of diastolic blood pressure was higher in D3 (86 +/- 5%) and D2 (85 +/- 7%) than in C (80 +/- 7%, p < 0.02). This ratio was also elevated in group D4 (94 +/- 8%) compared to D3 (p < 0.05) corresponding to a marked smoothing of the diurnal blood pressure curve. The 24-h heart rate (beats per min) was significantly elevated in D3 (84 +/- 8) and D2 (80 +/- 10) compared with C (73 +/- 11, p < 0.05 Tukey's test), suggesting the presence of parasympathetic neuropathy.(ABSTRACT TRUNCATED AT 250 WORDS)

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.

The number of elderly patients with insulin-dependent diabetes mellitus (IDDM) is increasing because of the prolongation of life due to the improvement of diabetic control. For better management of elderly patients with IDDM, we investigated the clinical and genetic characteristic of older patients with IDDM in comparison with younger patients. The subjects studied consisted of 19 patients with IDDM treated at the Department of Geriatric Medicine, Osaka University Hospital. Among the 19 subjects, 7 patients (37%) were more than 50 years old, including 3 patients (16%) more than 65 years old. The clinical and genetic characteristics of these 7 patients (older patients group) were compared with those of 12 patients (younger patient group) whose age was less than 50 years old. The age at onset of IDDM was significantly higher in older patient group (46 +/- 13 years old; mean +/- SD) than in younger patient group (34 +/- 6 years old). There was no significant difference in the duration of IDDM between older and younger patients (13 +/- 6 and 12 +/- 8 years, respectively). There were no significant differences in daily insulin dose, glycemic control (fasting plasma glucose and HbA1c levels) and glycemic stability as measured by the standard deviation of 10 measured fasting plasma glucose levels between the two groups. The frequency of diabetic retinopathy and neuropathy in the older patients was slightly, but not significantly, higher than that in younger patients. The frequency of diabetic nephropathy was similar in both groups.(ABSTRACT TRUNCATED AT 250 WORDS)

In theory, transplantation of the islets of Langerhans is the method of choice for the treatment of insulin-dependent diabetes. In actual fact, medical teams who have been working on this subject for about two decades have met with the problem of islet isolation, and for the time being this treatment cannot be considered effective. Pancreas transplantation gives satisfactory results in diabetics with renal impairment when it is coupled with kidney transplantation. However, it cannot yet be applied to all diabetics as its results are mediocre when performed alone, and it requires chronic immunosuppression. Pancreas transplantation not only increases the quality of life but also has the advantage of acting on degenerative complications: it may improve diabetic nephropathy, retinopathy and neuropathy. The results obtained are getting better year after year, and they are now close to those observed with other organ transplantations.

The patient was a 63-year-old male who was with having diabetes mellitus since 1967. Hemodialysis was carried out from June 1983 for diabetic nephropathy. Neuropathy and retinopathy were already present at that time. He complained pain in penile glans from the middle of June 1990. Three month later, partial penectomy was performed because of the development of black-mummy-shaped necrosis on the whole glans. Histopathological examination widely revealed luminal obstruction and formation of thrombus due mainly to vascular lesions as a result of diabetes mellitus. As far as we know, case reports of diabetes mellitus complicated with penile necrosis are extremely rare, and this present case seems to be the 2nd one in Japan and the 5th one in the world, including those reported previously in the West.
