We examined the long-term effect of pravastatin, a new potent inhibitor of endogenous cholesterol biosynthesis, on glucose and lipid metabolism in hyperlipidemic NIDDM. Ten patients (5 on sulfonylurea, 5 on diet) were studied over 12 months. Five were WHO type IIa and 5 were type IIb. Blood was taken before and then 1, 6 and 12 months after initiating 10 or 20 mg daily of pravastatin. The cholesterol concentration in whole plasma and very low density lipoprotein (VLDL), plasma triglyceride and apolipoprotein (apo) B were all significantly decreased within the first month. These changes lasted for 1 year. High density lipoprotein (HDL)-cholesterol increased in the first month but returned to base line thereafter. Low density lipoprotein (LDL)-cholesterol tended to decrease in the first month, and was suppressed significantly from the 6th month (11%) to the 12th month (16%). The effect of pravastatin on LDL-cholesterol in NIDDM was slower and weaker than that published for non-diabetic hypercholesterolemia. Therefore, the mechanism by which pravastatin suppresses plasma cholesterol levels in these two conditions may differ. After 1 year, no adverse effects were noted on hematopoietic, hepatic or renal function. Blood glucose level, hemoglobin A1c and the insulin response to oral glucose were unchanged. In addition, serum creatine phosphokinase showed no abnormal increase. Careful ophthalmological examinations before and after pravastatin treatment revealed no development of new lenticular opacities. Thus, pravastatin appears to be a safe and effective drug for the long-term treatment of NIDDM with hypercholesterolemia.

We evaluated the prevalence of peripheral neuropathy by clinical and electrophysiological criteria and the prevalence of autonomic parasympathetic nerve dysfunction by heart-rate variation during deep breathing (expiration-to-inspiration ratio [E:1]) in 132 newly diagnosed non-insulin-dependent diabetic (NIDDM) subjects aged 45-64 yr and 142 randomly selected nondiabetic control subjects. The relationship of nerve dysfunction to the degree of hyperglycemia and insulin-secretion capacity were also investigated. Single and scattered symptoms and signs of peripheral neuropathy were found in both diabetic and control subjects. Symptomatic polyneuropathy was found in 1.5% of diabetic subjects but none of the control subjects. Polyneuropathy defined by clinical signs was found in 2.3% of the diabetic subjects and 1.4% of the control subjects. No subjects with both symptoms and signs were seen. Nerve conduction velocities (NCVs) were significantly slower in diabetic than control subjects. Polyneuropathy according to electrophysiological criteria was found in 15.2% of diabetic subjects but was not found in any control subjects. Electromyographic abnormalities were more common in diabetic than control women, but not significant differences were found in men. The resting heart rate was higher in diabetic than control women, but no significant difference was found in men. The mean E:I was significantly lower in diabetic men and women than control men and women. An abnormally low E:I was found in 9.2% of the diabetic men, 3.3% of the control men, 3.3% of the diabetic women, and none of the control women. NCV parameters, but not E:I, were inversely correlated with fasting blood glucose and glycosylated hemoglobin levels. A positive correlation between NCV and fasting and postglucose serum insulin levels was found in both groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Although oral glucose tolerance test (OGTT) has been the key examination in early diagnosis of diabetes mellitus, but it still has some problems. It may be affected by some physiological or pathological changes and also requires frequent blood sampling. We investigated the usefulness of measuring the level of glycated hemoglobin (GHb) or HbA1 and HbA1c in screening or early diagnosis of diabetes mellitus. OGTT was performed and fasting levels of HbA1 and HbA1c were measured in 168 subjects. According to the diagnostic criteria of WHO for 75g OGTT, 31 subjects were classified as normal, 35 as having impaired glucose tolerance test (IGT) and 102 as diabetics. The method used for determination of HbA1 and HbA1c was high pressure liquid chromatography (HPLC). The total discovery rate for GHb in diabetic patients was 87%. In patients with fasting level of plasma glucose (FPG) greater than or equal to 8 mmol/L the discovery rate was 100%, while in those with level of FPG less than or equal to 7.94 mmol/L the rate was 80%. Thus, GHb is very useful in screening and early diagnosis of NIDDM (type II), especially diabetes mellitus of the elderly.

Factors to be checked concerning local and systemic condition were studied statistically in order to clarify the methodology for clinical management of diabetic retinopathy. NIDDM (n = 1517) and IDDM (n = 30) persons participating in baseline and follow-up examinations were included. The vitreous fluorophotometric values were selected for local check factors. Glycosylated hemoglobin was selected for systemic check factors. To determine the retinopathy status at both the baseline and follow-up examinations, all fundus photographs were graded in a masked fashion, using the author's classification scheme (1983) which specified six levels of retinopathy for each excepted from the interrupted proliferative retinopathy. Level 0: no retinopathy, Level 1: microaneurysms only (AI), Level 2: microaneurysms and retinal hemorrhages (AII), Level 3: preproliferative retinopathy (soft exudates, increased capillary occlusion and intraretinal microvascular abnormalities) (BI), Level 4: neovascularization elsewhere (BII), Level 5: neovascularization of the disc (BIII), Level 6: vitreous hemorrhages or proliferative tissue (BIV, V). A positive correlation between the progression of retinopathy and glycosylated hemoglobin or vitreous fluorophotometric values were observed. The coefficient of correlation was 0.67 between posterior vitreous fluorophotometric values and levels (scores) of retinopathy. The coefficient of correlation was 0.41 between glycosylated hemoglobin and levels of retinopathy. These data suggest that these two factors can predict the progression of diabetic retinopathy.

The effects of individual teaching imparted during routine diabetologic counselling on the knowledge concerning diabetes and metabolic control, were assessed in 42 outpatients (28 IDDM; 14 NIDDM), attending the diabetic clinic (study group, SG). We evaluated the outcome of a multiple-choice questionnaire and fasting blood glucose (FBG), 24-h urine glucose (UG), mean regulation index (MRI) and glycated hemoglobin (HbA1), before and 60 days after providing information about diet (D), physical exercise (E) and hypoglycemic drugs (HD) or insulin therapy (IT). Results were compared with those obtained in a group of 57 age- and sex-matched patients (36 IDDM; 21 NIDDM) who did not receive individual teaching (control group, CG). Knowledge concerning diabetes at the second evaluation was significantly higher (p less than 0.001) in SG than in CG for D and IT, although an improvement was observed in all items. SG patients showed a significant improvement of knowledge (p less than 0.05) for D, a not significant improvement for HD and IT and no change for E. No change was observed for HbA1, MRI and UG, while a significant decrease (p less than 0.05) was observed for FBG in SG. At the second evaluation, FBG of SG patients was significantly lower (p less than 0.05) than that of CG patients. Our results go to show that individual teaching can improve the level of knowledge of patients without affecting metabolic control. Individual teaching during routine diabetologic counselling represents in our opinion an effective and economic educational model.

Neonatal polycythemia is a perinatal complication in infants of diabetic mothers. The cord CBC (complete blood counts), serum iron, transferrin and ferritin concentrations were studied in newborn infants of 9 GDM (gestational diabetes), 21 NIDDM (noninsulin-dependent diabetes mellitus), and 8 IDDM (insulin-dependent diabetes mellitus) mothers. The RBC (red blood cell) count, Hb (hemoglobin) and Hct (hematocrit) of these infants were higher than control infants. There was no difference between the serum iron concentration of the infants of each group diabetic mothers and the infants in the control group, but the transferrin concentration was significantly higher and the ferritin was significantly lower in the infants of diabetic mothers than in those of control mothers. There was a significant negative correlation between transferrin and ferritin (r = -0.491 p less than 0.001). Erythropoiesis is considered to be enhanced in the fetuses of diabetic mothers, and the iron needed for erythropoiesis is reportedly transported from the mother to the fetus according to the demands of the fetus, but the iron storage was shown to be reduced in the fetuses of diabetic mothers.

The effect of a 4-month exercise program on measures of cardiovascular disease (CHD) risk was observed in women (mean age = 59.2 +/- 3.9 years) of postmenopausal years with NIDDM, who demonstrated fair to normal control of blood glucose control. The women were randomly assigned to either an exercise (n = 5) or control (n = 5) group. Initially, both groups had a similar body mass index, resting heart rate and blood pressures, blood glucose and hemoglobin A1. After 4 months, the exercise group demonstrated a 32% increase (P less than 0.03) in both absolute and relative maximum oxygen uptake (VO2) while the control group remained unchanged. Significant differences were found between the exercisers and non-exercisers for absolute (F(1,8) 4.94, P = 0.057) and relative (F(1,8) 7.67, P = 0.024) maximum VO2 from pretest to posttest. Body weight (kg) and body fat (%) remained unchanged for both groups. Although total cholesterol was found to be reduced by 13% for the exercise group (P less than 0.03) and 11% for the controls (P less than 0.01), a 15% decrease (P less than 0.03) in high-density lipoprotein (HDL) was observed for the control group, only. Hence, a marked difference (P less than 0.03) in the risk ratio was observed between the exercise and control groups. These data suggest that physical exercise may play an important role in the maintenance of HDL mass and in the reduction of CHD risk factors in women of postmenopausal years with NIDDM.

We report the clinical records of 45 children with abnormalities regarding glycemic regulation characterized by a non-insulin deficient hyperglycemia (NIDH), known under the different names of chemical diabetes, sub-clinical diabetes and more recently MODY. These 45 children belong to 31 families with 532 relatives comprising 137 cases of NIDH which could have been studied. The symptoms of this biochemical abnormality, the pathophysiology of which is not yet clearly understood, are the following: lack of clinical manifestations, except for a variable and intermittent glycosuria; constant abnormal glucose tolerance tests, above 97 percentiles of the reference value with some variations over time; normal immunoreactive insulin levels; percentage of glycosylated hemoglobin at the upper range of normal; dominant autosomal genetic transmission and no association with HLA markers like in insulin-dependent diabetes; lack of degenerative complications of the micro-angiopathic type, at least on these cases even after more than 30 years of follow-up; finally, no tendency towards insulin-dependent diabetes. The NIDH should not be confused with the slow and progressive beginning of insulin-dependent diabetes for which prolonged delay is needed to affirm the diagnosis. The frequency of the biochemical phenomena is about 1.8% of the cases of authentic diabetes mellitus occurring before the age of 15.

The effects of insulin on the lipid values of nonobese non-insulin-dependent diabetic (NIDDM) Arab women requiring insulin was investigated to find whether these patients have the same coronary artery risk factor related to lipid levels. In this study, 55 NIDDM women on insulin therapy (mean age 28 +/- 8.1 yr and duration of disease 5 +/- 1.2 yr) and 70 control subjects (matched for sex, age, and body mass index) were studied for their plasma levels of lipids, lipoproteins, and apolipoproteins. Concentrations of total cholesterol, very-low-density lipoprotein cholesterol, low-density lipoprotein (LDL) cholesterol, triglyceride (TG), LDL TG, high-density lipoprotein triglyceride (HDL TG), phospholipid, glucose, glycosylated hemoglobin (HbAtc), apolipoprotein B (apoB), LDL-apoB, and apoB/apoAl were significantly elevated in diabetic women compared with control subjects. There was no significant change in the levels of apoAll in plasma and lipoprotein fractions. Concentrations of HDL cholesterol (chol), HDL2-chol, HDL3-chol, plasma apoAl, HDL2-apoAl, HDL3-apoAl, and HDL-apoAl were significantly lower in diabetic women than in control subjects. There was no significant correlation between glucose or HbAtc and most of the lipids, lipoprotein lipids, and apolipoproteins measured. Despite normal body weight and insulin therapy, abnormalities in lipids, lipoprotein lipids, and apoB persisted in NIDDM patients compared with control subjects. Our data may favor an enhanced affinity toward atherosclerosis in these patients.

This study was initiated in order to evaluate the clinical efficacy of glipizide treatment in 18 patients with non-insulin dependent diabetes mellitus in poor glycemic control with insulin. Insulin dose was kept constant, and various facets of carbohydrate and lipid metabolism were evaluated before and from 4-6 months after the addition of glipizide. The results indicated that fasting and post-prandial glucose concentration were significantly (P less than 0.001) reduced following glipizide treatment, associated with a commensurate fall in glycosylated hemoglobin concentration. The average fall in fasting plasma glucose concentration in the total patient group approximated 60 mg/dl, and the mean decrement in 8 of the 18 patients who had a fall of more than 70 mg/dl in fasting glucose was 93 mg/dl. These results demonstrate that the addition of glipizide to the treatment program of patients with non-insulin dependent diabetes mellitus poorly controlled on insulin can lead to substantial clinical benefit.
