Changes of glucose and lipid metabolism in NIDDM hypertensive patients during treatment with a new dihydropyridine derivative, nilvadipine, were examined by a randomized, crossover study comparing the results with those elicited by captopril in 18 patients for 12 weeks each. Nilvadipine (8 mg per day) and captopril retard (75 mg per day) caused a sufficient decrease in blood pressure without changing the pulse rate. Nilvadipine and captopril did not significantly change fasting plasma glucose, hemoglobin A1c, serum cholesterol, triglycerides, high-density lipoprotein cholesterol or apoprotein A-I, A-II and B levels in either of the 12-week treatments. In 75-g oral glucose tolerance tests carried out three times in each patient (before treatment and after 12 weeks of treatment with each drug), changes in plasma glucose and serum insulin levels were not significantly different among the three tests. These results demonstrate that nilvadipine as well as captopril are antihypertensive drugs without adverse effects on glucose and lipid metabolism in hypertensive patients with NIDDM.

Short-term studies have suggested that analogs of prostaglandin E may have favorable effects on the carbohydrate and lipid metabolism in patients with type II diabetes mellitus. The present study was undertaken to investigate the long-term effects of a prostaglandin E1 analog on the regulation of glycemic control and plasma lipids. Twenty patients with type II diabetes received enisoprost, 300 mcg/day, for three months. Fasting serum glucose, glycosylated hemoglobin, insulin and C-peptide levels as well as triglyceride, total cholesterol, high density lipoprotein cholesterol and its subfractions, apolipoproteins B and AI and post-heparin lipoprotein lipase and hepatic triglyceride lipase activities were determined. During the first month, enisoprost treatment caused significant decreases in plasma glucose (baseline = 8.72 +/- 0.39 mmol/L, 4 week = 7.78 +/- 0.5 mmol/L, change = -0.94 +/- 0.28 mmol/L, p less than 0.01) and total cholesterol (baseline = 5.30 +/- 0.23 mmol/L, 4 week = 5.01 +/- 0.26 mmol/L, change = -0.28 +/- 0.06 mmol/L, p less than 0.05). The decrease in cholesterol level was due to a reduction in high density lipoprotein, specifically in high density lipoprotein2 fraction (baseline = 1.29 +/- 0.1 mmol/L, 4 week = 1.12 +/- 0.08 mmol/L, change = -0.018 +/- 0.04 mmol/L, p less than 0.05 for the former and baseline = 0.40 +/- 0.06 mmol/L, 4 week = 0.27 +/- 0.03 mmol/L, change = -0.12 +/- 0.03 mmol/L, p less than 0.05 for the latter): All of these values returned to the pretreatment levels despite continuation of enisoprost.(ABSTRACT TRUNCATED AT 250 WORDS)

The superoxide anion (O2-) production in polymorphonuclear leukocytes stimulated by phorbol myristate acetate in IDDM and non-insulin dependent diabetes mellitus (NIDDM) was determined by the method of Johnston et al, compared with that of each age matched controls. And the correlation between O2- production and hemoglobin (Hb) A1 and A1c value was investigated. The O2- production in IDDM was 24.4 +/- 7.4 (mean +/- SD, n mol per 4 X 10(5) cells) at 10 min. and 51.4 +/- 8.7 at 30 min., in NIDDM each 31.6 +/- 9.3, 60.2 +/- 14.4, and in controls each 40.5 +/- 4.2, 72.4 +/- 3.1. O2- production in IDDM was significantly lower than that in NIDDM (p less than 0.001 at 10 min. and p less than 0.01 30 min.) and controls (p less than 0.001 at 10 and 30 min.). O2- production at 10 and 30 min. possessed a negative correlation with Hba1 and A1c value (HbA1: p less than 0.01 at 10 min. p less than 0.05 at 30 min., HbA1c: p less than 0.01 at 10 and 30 min.). These findings suggest that impaired O2- production might be one of the factors accounting for depressed bactericidal activity of polymorphonuclear leukocytes in IDDM, and that a protracted hyperglycemia might shed some effect on O2- production.

Aldose reductase (EC 1.1.1.21) is implicated in the pathophysiology of diabetic complications. In this paper we determined the activities of aldose reductase and ATPases of the erythrocytes in 17 patients with Type 2 (non-insulin-dependent) diabetes mellitus (NIDDM). In the aldose reductase assay we used fluorometric method to avoid the disturbance of hemoglobin. With dihydronicotinamide adenine dinucleotide (NADH), we verified it was aldose reductase but not aldehyde reductase II that was activated in the erythrocytes of the patients with NIDDM. The aldose reductase activity of the erythrocytes in the patients was significantly higher (P less than 0.01) than that in the controls. The activity of Na+/K(+)-ATPase of the patients was significantly lower (P less than 0.01) than that of the controls. The activities of Ca(2+)-ATPase and Mg(2+)-ATPase on the erythrocyte membranes of the patients were similar to those of the controls. At the same time we measured the seven nucleotide concentrations in the erythrocytes of the patients. In this experiment we used ultrafiltration method, instead of acid precipitation to make it possible to determine dihydronicotinamide adenine dinucleotide phosphate (NADPH) and NADH. The concentrations of ATP, ADP and AMP were similar to those of the controls. The concentrations of NADPH, NAD+ and NADH in the erythrocytes of the patients were significantly lower (P less than 0.01, 0.05 and 0.05 respectively) than those of controls. The concentration of nicotinamide adenine dinucleotide phosphate (NADP+) in the patients was significantly higher (P less than 0.01) than that of controls.

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.

Acarbose (Bay g 5421, Glucobay; CAS 56180-94-0) inhibits alpha-glucosidases of the small intestine and thus delays glucose release from complex carbohydrates. It is therefore efficient as a first-line drug in the treatment of noninsulin-dependent diabetics (NIDDM) insufficiently treated with diet alone. Information is scarce whether under acarbose treatment the lipid metabolism can also be improved. Therefore the changes of triglycerides, cholesterol and HDL-cholesterol were analyzed in a randomized double-blind placebo-controlled trial. In brief, 94 NIDDM aged 43 to 70, after a pretreatment period of at least 3 months, were treated with 100 mg acarbose t.i.d. or placebo for 24 weeks. The patients were recruited after a 4-week screening phase with reinforcement of diet. The most impressive results of acarbose treatment were lowering of blood glucose and insulin, especially in the postprandial state, and of HbA1 (glycosylated hemoglobin). Results on lipids: The initial serum cholesterol levels showed a broad spectrum. Low concentrations remained unchanged under acarbose, while high concentrations (the upper tercile) decreased from 273 to 251 mg/dl. This effect was statistically significant compared to placebo. HDL-cholesterol levels increased continuously under acarbose and placebo as well thus indicating some study effect. Similarly, fasting triglycerides leveled down under acarbose and placebo. However, drastic differences appeared in postprandial triglycerides which were checked 1 and 5 h after a test meal given at entry and at finish of the study. The lowering by acarbose compared to placebo was highly significant for the 1 h postprandial concentrations. It is concluded that acarbose treatment can reduce elevated cholesterol concentrations and postprandial triglyceride concentrations.(ABSTRACT TRUNCATED AT 250 WORDS)

The efficacy and safety of gliclazide (Diamicron) were studied in 29 NIDDM patients (19 men and 10 women aged 25-68 years) who failed to improve with diet or with diet plus a sulfonylurea. All patients were overweight and had fasting blood glucose levels consistently above 150 mg/dl (8.24 mmol/l). After withdrawal of oral hypoglycemics where applicable, they received 40 mg Diamicron three times daily with meals. The dose was increased by 40-80 mg/day until optimum control was obtained or up to a maximum of 320 mg/day. Treatment lasted for 12 months. At the end of this period the mean fasting blood glucose level had fallen by 35% from 238 to 154 mg/dl and the mean 2-h postprandial blood glucose level had fallen by 28% from 237.7 to 195 mg/dl. The mean glycosylated hemoglobin level also fell by 30% from 10.10 to 7.02%, i.e. within the normal range. In addition, there was a 19% fall in triglyceride and a 10% fall in cholesterol levels, with no change in body weight. No changes were observed for serum insulin, C-peptide and glucagon levels, thyroid function tests, blood counts, liver and kidney function tests, uric acid, electrolytes, blood pressure or heart rate. No clinical or ECG abnormalities were observed in patients with or without cardiovascular disease. There were two presumptive hypoglycemic reactions, but these did not require treatment. Adverse effects were reported by 22 patients, including dizziness and light-headedness, diarrhea, nausea, palpitations and pruritus, but none required modification of Diamicron therapy. The results therefore show that Diamicron is safe, effective and well tolerated in suitably selected NIDDM patients.

In the present study a randomized cross-over design was used to determine the clinical usefulness of adding 16 g of beet fiber to the ordinary diet of non-insulin dependent diabetic (NIDDM) out-patients. In addition, fiber effects on the gastrointestinal hormone responses to a standardized test meal were evaluated. The study included five patients treated with diet alone and eight patients treated with diet and sulphonylurea (SU). Beet fiber supplementation resulted in a 10% reduction (P less than 0.01) of serum cholesterol in SU-treated patients. No differences were found for fasting blood glucose, glycated hemoglobin, serum triglycerides or body weight. In the diet-treated patients, fasting plasma somatostatin was elevated during the fiber period. However, postprandial responses of insulin, C-peptide, glucagon, gastric inhibitory peptide and somatostatin were not influenced by an increased fiber intake in any group. All patients experienced mild gastrointestinal discomfort during the fiber period. In view of the limited metabolic benefit of beet fiber treatment we conclude that there is little use for this type of dietary fiber in the routine treatment of patients with NIDDM.

Plasma lipids, lipoproteins and apolipoproteins (apo) were analysed in 30 young Arab IDDM and 50 young insulin-requiring NIDDM women. The mean age of IDDM and NIDDM groups was 20.2 and 34.5 years, and mean duration of diabetes was 5.7 and 4.6 years, respectively. Two groups of 40 and 60 healthy women (matched for age and BMI) provided corresponding control groups. In comparison with control subjects, diabetics showed marked increases in the following parameters: total cholesterol (TC), low density lipoprotein (LDL) cholesterol, total triglycerides (TG), very low density lipoprotein (VLDL) triglycerides, phospholipids, apoB, LDL apoB, glucose and glycosylated hemoglobin (HbA1c) as well as the ratios of total cholesterol/high density lipoprotein (HDL) cholesterol, LDL-cholesterol/HDL-cholesterol, LDL cholesterol/high density lipoprotein (HDL) cholesterol, LDL-cholesterol/HDL-cholesterol, LDL cholesterol/high density lipoprotein 2 (HDL2) cholesterol and apoB/apoAI. Plasma LCAT activity, concentrations of HDL3 apoAI and apoAII in plasma and lipoprotein fractions were normal in both the diabetic groups. Levels of C-peptide, HDL, HDL2 and HDL3 cholesterol, plasma apoAI, HDL apoAI and HDL2 apoAI were markedly decreased in the diabetic groups as compared to their corresponding controls. There was no significant correlation between fasting glucose or HbA1c and any of the above parameters. Despite insulin therapy in both the diabetic groups studied, abnormalities in lipids, apoB and apoAI still persisted. Our data suggest a possible higher risk of atherosclerosis in these patients.

Thirty-six patients were admitted to an open study designed to evaluate the long-term efficacy of gliclazide in the treatment of type II diabetes mellitus. Results from 27 of these patients were analyzed at 36 months, 21 at 48 months, and 16 at 60 months of follow-up. An overall reduction in fasting and postprandial blood sugar was observed (p less than 0.001). Total glycated hemoglobin (HbA1) fell significantly (p less than 0.001), to revert to values within the reference range in over 80% of cases. Body weight remained stable over a period of observation ranging from 36 to 60 months. The incidence of subsequent failure of oral treatment was 2% per annum. These results show that long-term treatment of type II diabetes with gliclazide leads to satisfactory results, with practically no side effects.
