Atherosclerotic manifestations are more common and precocious in diabetics than in the general population. Due to the increased cardiovascular risk, a primary or secondary (to diabetes mellitus) lipoprotein disorder in diabetics has to be carefully considered. 27 diabetics (15 NIDDM and 12 IDDM) with dyslipidemia (14 type IV, 8 type IIa and 5 type IIb) were divided in 3 groups and treated with 3 different hypolipemic drugs (Group A: pantethine 600 mg/day; Group B: acipimox 500 mg/day; Group C: bezafibrate 600 mg/day) to test their efficacy and acceptancy. Body weight, Hb A1-c, serum lipoproteins have been measured before and during the 6 months treatment. A significant variation of lipidemic pattern was observed in Group C: a decrease of cholesterol (-20%), triglycerides (-40%), LDL (-24.4%) and apo B (-26.8%) with an increase of HDL (+23.6%). Pantethine and acipimox were more effective on triglycerides (-37.7% and -23.3% respectively). Cardiovascular risk (CT tot/CT HDL) was significantly reduced with acipimox and normalized with bezafibrate.

Conflicting data have been reported about the impaired sensitivity to the inhibitory effect of prostacyclin (PGI2) in platelets from patients with diabetes. In the present paper we investigated binding of and sensitivity to PGI2 of platelets from insulin dependent (IDDM) (n = 9), non insulin dependent (NIDDM) (n = 8) diabetics and two groups of ten healthy subjects of equivalent age in relation to platelet lipidic content. Platelet sensitivity to PGI2 (PGI2 IC50) was found not significantly changed in diabetics as compared to controls; similarly, no significant differences of the number of high affinity receptors for PGI2 in platelets from patients with IDDM and NIDDM were observed. Platelet sensitivity to PGI2 and PGI2 receptors were found to be significantly related to platelet cholesterol content (r = 0.89, p less than 0.001 and r = -0.80, p less than 0.001 respectively). In conclusion platelet PGI2 receptor changes are not detectable in diabetics in good metabolic control, but could take place when platelet lipid composition is altered.

The serum ketone response to glucagon was measured in 10 patients with IDDM and 37 with NIDDM. In both groups, serum 3-hydroxybutyrate increased significantly after intravenous injection of 1 mg glucagon. The difference between the serum level of 3-hydroxybutyrate at 30 min and basal level [delta 3-OHBA(30')] was 133 +/- 25 mumol/l in the patients with IDDM, 13 +/- 8 mumol/l in those with NIDDM treated by diet alone or with oral hypoglycemic agents and 23 +/- 13 mumol/l in those with NIDDM treated with insulin. The delta 3-OHBA(30') was significantly greater in IDDM patients than in both groups of NIDDM patients (P less than 0.001). The delta 3-OHBA(30') was greater than 87 mumol/l in eighty percent of IDDM patients, but smaller than 87 mumol/l in both groups of NIDDM patients. The delta 3-OHBA(30') was correlated with the difference between the plasma level of C-peptide at 6 min and basal level [delta CPR(6')] (r = -0.540, P less than 0.001). The delta 3-OHBA(30') was not correlated with fasting plasma levels of glucose, fructosamine or hemoglobin A1c. These observations show that measurement of the serum ketone response to glucagon is a useful marker of insulin dependency. In order to determine insulin dependency, the simultaneous measurement of concentrations of ketones and C-peptide is indicated during the glucagon stimulation test.

The plasma glucose and insulin responses were determined in 10 NIDDM female patients following the ingestion of tropical fruit containing 25 g of carbohydrate. The five tropical fruits were pineapple, mango, banana, durian and rambutan. Blood was drawn at 0, 30, 60, 120 and 180 min, respectively. The results showed that the glucose-response curves to mango and banana were significantly less than those to rambutan, durian and pineapple (P less than 0.05). Only the glucose area after mango ingestion was significantly less than the glucose areas of the other fruits (P less than 0.05). The insulin response curve and insulin area after durian ingestion was statistically greater than after ingestion of the others. We concluded that after mango ingestion, the glucose area was lower than it had been after rambutan, durian and pineapple ingestion and the insulin area was lower than that after durian ingestion of equivalent carbohydrate content in type 2 (NIDDM) diabetes.

In order to provide further insights into the conflicting reports of associations between diabetes and uric acid metabolism, we studied 175 adult diabetic patients (56 IDDM, 119 NIDDM) and 114 matched control subjects. Plasma uric acid (PUA) concentrations were not significantly different between diabetic and control subjects, despite increased urinary urate in diabetic patients. There were no significant associations, in diabetic patients, between PUA and (i) type of diabetes, (ii) glycaemic control, (iii) retinopathy and (iv) proteinuria. Plasma urate did not correlate with the KG constant for glucose disposal rate during IVGTT, thus indicating that PUA may not be related to insulin action. In a separate study, PUA rose sharply, peaking at 30 min, and fell subsequently in both newly diagnosed NIDDM patients (n = 20) and subjects with impaired glucose tolerance (n = 15) in response to standard OGTT, in contrast to normal controls (n = 35) in whom PUA rose gradually to a peak at 120 min. Mean rise in PUA from baseline to peak was significant (P less than 0.05) in the diabetic group only. These differences in PUA response during an OGTT between subjects with abnormal glucose metabolism and normal controls may be a feature in the metabolic evolution of diabetes and need further investigation.

Kidney disease is a primary cause of morbidity and mortality in diabetic patients. Factors that predetermine development of nephropathy remain unknown. Poor glycemic control, insulin requirement, duration of diabetes and family history of hypertension appear to be associated with an increased risk. Arterial hypertension, which is twice as common in diabetic patients as in the normal population, accelerates the progression of diabetic nephropathy. The pathophysiologic mechanisms responsible for hypertension appear to be different in IDDM and NIDDM. In IDDM, hypertension occurs usually as a consequence of diabetic renal disease. Conversely, the pathogenesis in NIDDM appears to be multifactorial. In either condition, aggressive blood pressure control is the single most important intervention proven to retard the progression of nephropathy. A stepped-care approach similar to that for essential hypertension with slight modifications is indicated in the treatment of the hypertensive diabetic patient with nephropathy. Nonpharmacological therapy, including dietary protein restriction, should be used as first step. Selection of the ideal antihypertensive must be based not only on efficacy but also on its side effect profile. Angiotensin converting enzyme inhibitors and calcium antagonists have a low incidence of side effects and do not induce metabolic disturbances. Therefore, they are the agents of choice for patients who do not respond to nonpharmacological therapy alone. Thiazide diuretics and beta-blockers should be used as first line therapy only for specific indications. Antihypertensive therapy combined with good glycemic control and dietary protein restriction constitute the standard of care for diabetic patients with hypertension and renal disease.

This study was undertaken to examine whether patients with non-insulin-dependent diabetes (NIDDM) are hypercalciuric and whether there is a pathophysiologic relationship between urinary calcium excretion (UCE) and the degree of diabetic nephropathy. Although UCE did not parallel the increase of urinary albumin excretion rate (AER) and the presence of hematuria was not corrected with the degree of UCE, we confirmed that 36% of diabetic patients have hypercalciuria and that the prevalence of hypercalciuria is more frequent in diabetic patients with normo- or microalbuminuria than in the controls. In 6 months, the AER of two hypercalciuric patients increased. However, the blood pressure and HbA1c of these two patients increased during the same 6 months. Therefore, it remains unclear whether hypercalciuria induced an increase in the AER of these patients.

To clarify the characteristics of diabetic nephropathy (DN) in Japanese patients with non-insulin-dependent diabetes (NIDDM), we analyzed the clinical course of 130 such patients who began dialysis treatment due to DN between 1978 and 1988 at the Diabetes Center of Tokyo Women's Medical College. Analysis of the clinical course prior to attending the Diabetes Center revealed that 64 (49.2%) of the patients neglected or discontinued their initial treatment for diabetes until the development of diabetic complications because of the lack of symptoms. The average duration of untreated diabetes in these patients was 10.7 +/- 4.6 years. The biggest problem for NIDDM patients was the absence of symptoms until the development of diabetic complications.

Insulin resistance appears as the pathophysiological basis of metabolic syndrome and NIDDM. In type 2 diabetics additionally we observe a delayed and prolonged postprandial insulin response. These both processes represent a pathophysiological and pathogenetic unity of disturbances. The prevention and therapy of insulin resistance, metabolic syndrome and type 2-diabetes with diet involves 3 main issues: reduction of energy uptake and of body weight in obese; Composition of meals concerning the principles of fat reduced lactovegetabile nutrition; guaranteeing of longer postabsorptive phases (between meals), to avoid a permanent postprandial hyperinsulinemia and development of insulin resistance. Anti-insulin resistance diet is therefore a carbohydrate enriched, fat-reduced (lactovegetabile) nutrition with not too frequent meals (longer meal-free phases) and mainly reduced energy intake in overweight.

In order to study the possible relationship between sleep apnea syndrome (SAS) and diabetes mellitus, we first examined the prevalence of SAS among 12,787 general patients (6554 males and 6233 females) who visited Katsumata Hospital at Nagoya, Japan. Among them, thirty-five males and five females were diagnosed as having SAS. The male patients were statistically analysed by the corrected Mantel-Haenszel chi-square test taking the body type into account, and it was found that the prevalence of SAS was significantly high both in a diabetic population and in a hypertensive one. Among 40 SAS patients of both sexes, 34 were given a glucose tolerance test (GTT) with oral administration of 75 g glucose. Thirteen showed a diabetic pattern, 12 a borderline pattern and only 9 had a normal pattern. All 13 diabetic patients had non-insulin-dependent type diabetes (NIDDM). The present results showed that SAS has a close relationship not only to hypertension but also to NIDDM.
