Seventy one patients with nutritional-metabolic obesity (II--IV degree) were examined, with or without hyperlipoproteinemia, treated in hospitals or sanatoria for 25 days. The effect of the hypoenergy diet regimen (5,94 kJ = 1460 cal) was studied, that was combined with an average daily import of 11 g esterified, apple pectin (in fruit pastes and drinks) upon the level of 6 serum lipid indices. A decrease (less than 0,05) of total cholesterol, triglycerides and some other lipid indices was established both in the patients with hyperlipoproteinemia type II (IIa and IIb) and type IV, in those without hyperlipoproteinemia syndrome as well. Due to the hypolipidemic effect established the newly produced articles with high esterified apple pectin are recommended in the complex treatment of the patients with obesity (with or without secondary hyperlipoproteinemeia.

Serum cholesterol is preferably transported by low density lipoproteins (LDL) and high density lipoproteins (HDL). Accordingly, it is generally referred to as LDL-cholesterol and HDL-cholesterol, respectively. In recent years, the vasoprotective role of HDL and the negative correlation between HDL-cholesterol and cardiovascular diseases have been discussed by a large number of authors. This paper discusses the metabolic, pathophysiological, and clinical importance of HDL and HDL-cholesterol from a gerontological point of view. Incorporation of cholesterol into HDL enables cholesterol to be eliminated from the vessels and catabolized in the liver through various mechanism (LCAT substrate, cholesterol esterification and transport, and competitive LDL inhibition). Results of epidemiological, clinical, angiographic, and experimental studies showed that there is a reduction in the concentration of HDL-cholesterol in the case of coronary and peripheral arteriosclerotic diseases. Determination of HDL-cholesterol (in connection with a calculation of LDL-cholesterol) allows the risk of arteriosclerosis to be diagnosed and prognosed, respectively. "Normal" values of HDL-cholesterol are between 35 and 55 mg/dl (0.9-1.4 mmol/l for males and between 45 and 65 mg/dl (1.2-1.7 mmol/l) for females. In women, there is noted a decrease with increasing age. Obesity, diabetes mellitus, hyperlipoproteinemia, high-fat and high-carbohydrate nutrition, and ovulation inhibitors tend to decrease the level of HDL-cholesterol. Physical conditioning, change in diet, reduction of weight, and certain drugs having an effect upon the lipid metabolism tend to raise the HDL-cholesterol level. Knowledge of problems associated with what is here referred to as HDL-cholesterol is of great clinical importance to gerontologists as regards the prevention and therapy of arterio-sclerotic and, more specifically, coronary diseases.

The authors studied the X-ray grams of soft tissues of the lower limbs of 120 patients with diabetes mellitus--54 males and 66 females and 42 control subjects (18 males and 24 females). The average age of the latter was 56.3 and of the patient--52. According to their characteristic the calcifications were localized in intima (spotted) and in media (linear). Besides localization, the extend (whole artery or partial) and degree (light, pronounced) of calcifications were determined. Mediocalcinosis in the arteries of lower limbs of diabetics was established to be almost four times more frequent than that among the controls, the arteries of the thighs, legs and foot being equally affected. In 1/3 of the cases the whole vascular system of the lower limbs was involved, being more frequent in males, as compared with females, with a statistical significance, and correlated significantly with age and duration of the disease. Mediocalcinosis was more frequent with statistical significance, in patients, treated with sulfonylurea preparations. Attempt was made to explain that fact, besides by the older age of those patients with some humoral and hormonal characteristics of diabetes of the elderly, sensitive to SU preparations namely: the presence of hyperlipoproteinemia, hypersomatotropism and relative hyperinsulinism, favouring the proliferation of the cells of media and deposition of calcium salts in it. No statistically significant correlation was found between the incidence of mediocalcinosis on the one hand and the type of diabetes, severity of the disease, occupation, past infections, the presence of hypertension, obesity, retinopathy and disorders of lipid metabolism--on the other.

Since first reporting the association of hyperlipoproteinemia with inner ear disease in a study of 300 patients in 1973, I have continued to focus attention on the presence of lipid abnormalities in patients with inner ear dysfunction. With over 1,400 patients now identified with both abnormal lipids and inner ear symptoms, it has become increasingly apparent that most patients seen by otolaryngologists because of Meniere's disease come from that same large population group who are prone to obesity, maturity-onset diabetes, coronary artery disease, and atherosclerosis. These patients share the common problem of being unable to handle refined carbohydrates well. Based on the reports and studies of many authorities, a hyperinsulinism exists in these conditions. These patients are helped by replacing refined carbohydrates with complex carbohydrates having increased fiber. When these conditions can be identified in patients with Meniere's disease, dietary management has been found to be the most effective therapy.

Hyperlipoproteinemia occurs commonly in diabetics and may contribute to early atherosclerosis in these patients. The effect of dietary carbohydrate restriction on lipid abnormalities has been examined in 42 newly diagnosed maturity-onset diabetics, in whom plasma lipoproteins were measured before treatment was started and at regular intervals during ten months of dietary therapy. Twenty-four patients (57%) had abnormal lipids when diabetes was first diagnosed. Nine were classed as Type II and 15 as Type IV hyperlipoproteinemia. Plasma lipids reverted to normal in half these patients after dietary treatment for one month. Only 8 diabetics (19%) showed persistent lipid abnormality after ten months' treatment: all had been unable to diet satisfactorily as judged by persisting obesity and hyperglycemia. The common lipoprotein abnormalities of maturity-onset diabetes can usually be returned to normal by the simplest possible carbohydrate-restricted diet, if patients adhere to this. Specialized and complex diets or lipid-lowering drugs are unncessary in the majority of patients.

The authors estimated the influence of dehydroepiandrosterone (DHEA) administration, a potential antiatherogenic agent, on serum lipids, sex hormones and insulin levels in male rabbits fed on an atherogenic diet. They concluded that (1) DHEA administration has an unfavorable impact on the serum lipid profile; (2) an atherogenic diet causes insulin resistance; (3) the glucose and insulin levels are not related to DHEA in normally fed rabbits and in rabbits with hyperlipoproteinemia; (4) an atherogenic diet causes a slight increase of estradiol concentration; (5) DHEA treatment has no significant effect on testosterone and estradiol concentrations in both normally fed rabbits and those on an atherogenic diet; (6) DHEA administration has an anti-obesity effect.

Serum pseudocholinesterase (PChE) was discovered in 1932. Since this protein mimics many of the catalytic properties of acetylcholinesterase, it has traditionally been referred to as PChE, even though its true biological function is unknown. Serum PChE is synthesized in the liver and secreted into the circulation as a sialated glycoprotein. Although no convincing evidence of biological function exists, a significant number of obese and diabetic patients have elevated levels of PChE. The same phenomenon is found in experimental animal models of obesity, diabetes and hyperlipoproteinemia. Streptozotocin-induced diabetic mice showed increased serum PChE activity concomitant with increased serum triacylglycerol and PChE activity declined with treatment. Iso-OMPA, a nontoxic inhibitor of serum PChE, reduced serum and liver triacylglycerols and serum VLDL in streptozotocin-induced rodent diabetes. These findings suggest that PChE may have a role in VLDL metabolism.

The purpose of this report is to propose standards for the successful treatment of obesity. This process is somewhat arbitrary because obesity is a multifactorial disease and because standards need revision as diagnostic and treatment techniques improve. Weight loss, the classic standard of success, does not account for individual variability. Reduction in other measures of body size, such as body mass index, percentage of excess weight, and body fat, may be preferable. Improvement in known complications of obesity (diabetes mellitus, hypertension, hyperlipoproteinemia, sleep apnea, and psychosocial problems) are equally valid measures of success. Because obesity is a chronic disease, maintenance of weight loss is included as a standard of success. Response to obesity treatment varies, and thus criteria to define minimal, intermediate, and full success for each variable are necessary.

Insulin resistance is found in association with obesity, non-insulin-dependent diabetes mellitus, and essential hypertension, which are all risk factors for atherosclerotic cardiovascular disease. Furthermore, hyperinsulinemia has been reported in familial combined hyperlipoproteinemia and endogenous hypertriglyceridemia. Finally, relatively high serum triglyceride and low high-density lipoprotein (HDL) cholesterol concentrations invariably accompany hyperinsulinemia. Whether insulin sensitivity is affected by the isolated presence of high levels of serum low-density lipoprotein (LDL) cholesterol has not been clearly established. We studied 13 subjects with heterozygous familial hypercholesterolemia (FHC) and 15 normocholesterolemic subjects selected to be free of any other known cause of insulin resistance. Thus FHC patients and controls had normal body weight and fat distribution, glucose tolerance, blood pressure, and serum triglyceride and HDL cholesterol concentrations, but were completely separated on plasma LDL cholesterol concentrations (6.05 +/- 0.38 v 3.27 +/- 0.15 mmol/L, P < .0001). Fasting plasma levels of glucose, insulin, free fatty acids (FFA), and potassium and fasting rates of net carbohydrate and lipid oxidation were superimposable in the two study groups. During a 2-hour euglycemic (approximately 5 mmol/L) hyperinsulinemic (approximately 340 pmol/L) clamp, whole-body glucose disposal rates averaged 30.4 +/- 2.3 and 31.1 +/- 3.0 mumol.kg-1 x min-1 in FHC and control subjects, respectively (P = 0.88). The ability of exogenous hyperinsulinemia to stimulate carbohydrate oxidation and energy expenditure and suppress lipid oxidation and plasma FFA and potassium levels was equivalent in FHC and control subjects.(ABSTRACT TRUNCATED AT 250 WORDS)

The clinical and biochemical characteristics of type III hyperlipoproteinemia are described in 64 patients (35 males and 29 females). Homozygosity for apolipoprotein E2, the presence of an abnormally cholesterol-rich very low density lipoprotein fraction (beta-VLDL) and an elevated ratio of very low density lipoprotein cholesterol to plasma triglycerides (> 0.3; normal ratio about 0.2) were the basis for the diagnosis. Mean serum cholesterol and triglyceride concentrations at the first visit in the clinic were 426 +/- 221 and 719 +/- 996 mg/dl, respectively. The mean age at diagnosis of the disorder was 49 years in males and 53 years in females. There was a high prevalence of obesity (72%), xanthomas (42%), and atherosclerosis (39%), especially peripheral vascular disease (31%). Early and correct diagnosis of this familial lipoprotein disorder seems necessary because of the prompt and beneficial response to therapeutic interventions.
