Studies of patients with alimentary-metabolic obesity, which were treated with pyridoxine and were maintained on a reduced diet, revealed a normalizing effect of the vitamin on some patterns of lipid metabolism. In patients, treated with pyridoxine, body weight, content of total lipids, cholesterol, phospholipids, glycerids and beta-lipoproteins in blood serum were decreased more distinctly as compared with patients, which were only maintained on a reduced diet. In hyperlipidaemia the positive effect of pyridoxine was more pronounced than in the cases with normal content of lipids in blood.

At present the two different mechanisms underlying the hypertriglyceridemia of diabetes are reasonably well defined. The rationale of therapy has grown from this knowledge. One form of hyperlipidemia is due to the hyperinsulinemia which results from the patient's resistance to insulin. The approach to treatment aims to overcome the insulin resistance. In most patients this is done by treating their obesity. The other form of hypertriglyceridemia results from insulin deficiency and is treated by bringing the patient's diabetes under control. There is strongly suggestive evidence that hypertriglyceridemia may be associated with a high risk of atherosclerosis. The reason for treating hypertriglyceridemia in general, and in the diabetic in particular, is to reduce this risk. However, it must be conceded that, at the moment, there is no information about the effect of lower triglyceride levels on the incidence of atherosclerosis. Hence much epidemiologic research is needed before our rationale for treatment can move from the realm of hope to the realm of definite proof. In the mean time an attack on this and the other risk factors is the best way we have to attempt to prevent the major complication of diabetes, atherosclerosis.

Type V hyperlipemia is not very common. The series of 54 cases descrubed here is the largest reported to date. Our observations were recorded when lipidograms showed the presence of chylomicrons and a large pre-beta-lipoprotein spot in the serum of fasting subjects. Type V hyperlipemia was often combined with other metabolic syndromes such as diabetes, hyperuricemia or gout, or obesity. Chronic alcoholism was also noted in half our subjects, in whom hyperlipemia quickly regressed after alcohol consumption ceased. Ischemic arterial complications, chiefly coronary, were found in one third of our cases, and the vascular risks accompanying this type of hyperlipemia rose considerably in patients with high blood pressure. Various type of treatment were administered, but all subjects were put on a special diet, comprising either the elimination of alcoholic drinks only, or, in addition to this, reduced carbohydrate or calorie intake. As a rule, these measures resulted in a distinct regression of lipid anomalies. Clofibrate or derivatives proved effective in cases where hyperlipemia failed to respond to dietary measures.

We carefully selected 30 men with primary gout, rendered asymptomatic by therapy, to examine the frequency and type of hyperlipidemia and hyperlipoproteinemia, with the objective of determining whether serum uric acid, alcohol intake, liver function, kidney function, and (or) drugs were participating in the secondary lipid disorder. Sixty-one age- and sex-matched men were used as controls. About 73% of the gout patients had hypertriglyceridemia, 1.6-fold the frequency found in the control group. Types IV and IIb lipoprotein electrophoretic patterns were most prevalent in the gout group. Neither alcohol intake nor hyperuricemia, per se, seems to be the cause of the lipid and lipoprotein disorder and cannot be related to liver or kidney dysfunctions. Obesity was the major underlying factor associated with the lipidemia. The study suggests that diet and, possibly, defective clearance of triglycerides may be etiologic factors associated with the abnormal serum triacylglycerol (triglyceride) and lipoprotein concentrations in these individuals.

Seven hundred and fifty asymptomatic European subjects aged 16 to 69 years from an urban general practice were screened for various coronary risk factors. Required information was completed for 98.9 percent of the total sample. The incidence of individual risk factors in males and females respectively were: smoking, 52.8 percent and 45.6 percent; obesity, 26.9 percent and 30.9 percent; definite hypertension, 5.6 percent and 4.0 percent; borderline hypertension, 5.3 percent and 5.1 percent; hyperlipidaemia, 12.8 percent and 8.0 percent; impaired glucose tolerance, 1.1 percent and 1.3 percent. Respective figures for males and females with regard to numbers of risk factors present were: one or more risks present, 68.5 percent and 66.9 percent; two or more, 26.5 percent and 23.5 percent; three or more, 8.0 percent and 4.5 percent; four risk factors present, 1.6 percent and 0.3 percent.

The aim of this study was to discover which of three major abnormalities of the genetically obese Zucker rat (fa/fa), namely hyperphagia, excess adiposity, and hyperlipidemia, is the first to appear prior to manifest obesity, i.e., before weaning. Suckling fa/fa rats, bred from heterozygous parents, were detected by sizing fat cells obtained from an inguinal fat pad biopsy. Cell hypertrophy was observed in fa/fa rats, compared to Fa/-littermates of the same sex, as soon as 5-7 days after birth. Prediction of fa/fa genotype at this age by this method was assessed using a series of 80 pups and proved to be totally successful. The identity of the "predicted" obese pups was confirmed morphologically at 6 weeks of age. Food (milk) intake was estimated from water turnover rates determined on 86 pups aged 2-8 days using tritiated water. The results show that 7-day-old fa/fa rats had heavier inguinal fat pads with larger adipocytes and higher lipoprotein lipase activity than their lean controls. There was no genotype effect on water intake adjusted to body weight during the first week of life. Moreover weight of stomach contents and triglyceridemia were similar in all animals at 7 days. These results show that excess adiposity develops in the fa/fa rat during the first week of life, before hypertriglyceridemia and hyperphagia, and raises the question of whether this adiposity results from a defect in energy expenditure or an abnormality of fat cell storage capacity, or both.

Non-nutritive sweeteners have been utilized in the diet of diabetic patients as agents to replace glucose and sucrose. Since saccharin might be removed from the market place, the nutritive sweeteners, fructose, xylitol, and sorbitol, are being considered as possible atlernatives. This review considers the effects of these nutritive sweeteners on the main dietary concerns in the diabetic diet, i.e., control of blood glucose levels, obesity, and hyperlipidemia. The potential side effects of these agents are also reviewed.

Obesity in the Zucker rat is accompanied by hyperlipemia, hyperinsulinism, insulin resistance, pancreatic hyperplasia, and islet hypertrophy. This study correlates the morphologic heterogeneity of isolated pancreatic islets with secretion of insulin and glucagon in the perifusion system. Islet size was arbitrarily defined as large (greater than 0.45 mm) or small (smaller than 0.12 mm). Protein content and volume (V = 4/3pir3) were calculated for groups and individual islets, respectively. Islets from obese rats secreted more insulin in response to glucose and aminophylline than islets from lean rats (peak 7.8 +/- 2.4 vs. 1.5 +/- 0.37 microU/islet/min, P less than 0.005). Insulin release was related directly to islet size and protein content. Small islets from lean and obese animals produced less insulin per islet than large islets (P less than 0.005). In terms of islet volume, however, large islets were inefficient insulin releasers as compared to small islets (P less than 0.005). Stimulation with Br-cAMP released glucagon from islets of lean but not from large islets of obese animals (peak 11 +/- 3.3 vs. 4.1 +/- 0.3 pg/microgram protein per minute, P less than 0.05). Arginine produced the same effect on glucagon release (P less than 0.05) as stimulation with Br-cAMP. The observed increased insulin release rates and the blunted glucagon response are related to islet size in the pancreas of the Zucker rat.

We have evaluated the incidence, long term evolution and pathogenesis of posttransplant hyperlipidaemia (HL) in 88 transplanted patients without nephrotic syndrome followed for 2 to 13 years by the same staff. Incidence of HL decreased strikingly over the years from 51% at 2 years to 25% at 10 years. This fall was due solely to the return to normal of the lipid profile in 13 patients between 2 and 8 years after transplantation. This progressive decrease should be taken into account when the frequency of posttransplantation dyslipaemia is assessed. The incidence of hyperlipidaemia increases with age. Above 40 years, hyperlipidaemia is more frequent in females than in males. Obesity and reduced renal function are both associated with a higher incidence of dyslipaemia. No relationship was found between lipid disorders and either steroid dosage or fasting blood glucose levels. Dyslipaemia appears thus to be due to the interplay of several factors. Normalisation of the lipid profile occurred in 13 patients without significant decrease in bodyweight, serum creatinine or prednisone dosage. At 8 years atheromatous lesions were not more frequent in dyslipaemic than in normolipaemic subjects.
