Fibrate derivatives are commonly used to treat hyperlipidaemia; however, the mechanism of the antilipidaemic action of these drugs is still unknown. The effect of clofibrate (fibrate derivative) administration for 14 days on lipogenesis and on malic enzyme (EC 1.1.1.40) and fatty acid synthase (EC 2.3.1.85) gene expression in brown and white adipose tissues and in the liver was examined in rats. The rate of brown adipose tissue lipogenesis in the clofibrate-treated animals was significantly lower than that of the control rats. The rate of liver and white adipose tissue lipogenesis was not affected significantly by clofibrate. In brown adipose tissue, the drug treatment resulted in a depression of fatty acid synthase and malic enzyme mRNA levels. The fatty acid synthase mRNA level did not change significantly in the liver, whereas the malic enzyme mRNA level increased approximately 6-fold in this organ after clofibrate treatment. The malic enzyme mRNA level in white adipose tissue increased about 2-fold, while the fatty acid synthase mRNA level was unchanged after clofibrate feeding. The results presented in this paper provide further evidence that the hypolipidaemia caused by treatment of rats with clofibrate cannot be related to the inhibition of fatty acid synthesis in the liver and white adipose tissue. These data also indicate that clofibrate exhibits tissue specificity.

Atherosclerosis of the carotid bifurcation is an observable sign of systemic disease driven by key risk factors and resulting in an epidemic of stroke, myocardial infarction, and vascular death worldwide. Aggressive integrative preventive interventions of controlling hypertension, hyperlipidemia, diabetes mellitus, smoking, systemic inflammation/infarction, depression, and hyperhomocyst(e)imia are needed in the medical management of these high-risk patients. Surgical indications for asymptomatic surgery may be recalled through the acronym CAROTID, which emphasizes knowledge of risk benefit to a particular patient, adequate disclosure, and physician--patient equipoise.

The hyperlipidemia posttransplant has been largely attributed to immunosuppressant agents. In the present work we evaluated the effect of oral administration of cyclosporine (5 mg/kg/day) and/or methyl-prednisone (1 mg/kg/day) on lipid composition and polyunsaturated fatty acid biosynthesis in normal adult male rats. The results obtained showed that both agents produced a delay on the growth together with a significant loss of body weight. In liver microsomal fraction from rats treated with methyl-prednisone, a depression in delta 6 and delta 5 desaturation activities, was observed. This effect was corroborated in the fatty acid pattern through the enhancement of linoleic and dihomo-gamma-linolenic acids, and a depression of arachidonic acid. Similar results were noticed in those rats treated with both drugs when compared to the controls. No changes were observed either in the amount of liver microsomal total lipids or in the fatty acid composition of kidney and testis microsomes, as well as in erythrocyte membranes, among the different groups studied. Cyclosporine alone produced a significant depression in plasma triglycerides and showed no modifications in the other lipid parameters studied compared to the controls. Fluorescence anisotropy measured in the different membranes was not modified by the several treatments used. In view of the aforementioned data, it can be stated that methyl-prednisone would be the responsible for many of the lipid disorders that can be observed in posttransplant patients when they are subjected to the combined immunotherapy with cyclosporine.

The rapidly rising prevalence of obesity, worldwide, has prompted re-evaluations of the definitions and diagnostic criteria, and of the extent of the burden it contributes to health care services. Although categorized arbitrarily for epidemiological purposes according to BMI > 25 kg/m2 ('overweight') and BMI > 30 kg/m2 ('obese'), the disease itself (ICD code E.66) is the process of excess fat accumulation. It leads to multiple organ-specific pathological consequences, particularly if there is a tendency to intra-abdominal fat accumulation. The simplest field method to identify obesity and risk of medical problems is the waist circumference, and this method has found a special role in health promotion. Risks begin with waist > 80 cm (women) or > 94 cm (men). As a broad generalization, obesity produces few symptoms below the age of 40 years, but then several symptoms often develop; tiredness, breathlessness, back pain, arthritis, sweatiness, poor sleeping, depression and menstrual disorders all being common. The symptoms are often attributed to diseases in other body systems. Metabolic diseases like diabetes, hyperlipidaemia and, hypertension develop later, but the mean BMI at diagnosis of diabetes is 28 kg/m2. Ultimately, obesity increases the likelihood of myocardial infarction, stroke and several major cancers, but its biggest impact on health, especially in the elderly, is probably the multiplicity of effects on other body systems. The greatest challenge for public health is to develop effective preventive measures, recognizing that BMI > 25 kg/m2 before the age of 20 years is a very strong predictor of obesity and ill health in adulthood.

Results of treatment of 104 patients aged from 47 to 82 years with stage IV talocrural ischemia (by A.V. Pokrovsky) due to diabetic macroangiopathy were analyzed. Significant depression of immune status was revealed: number of T- and B-lymphocytes decreased by 40-50%, phagocytosis--by 65-75%, number of immunoglobulins--by 25-30%. The majority of the patients had endotoxicosis, hypercoagulation and hyperlipidemia; the correction of it by hemosorption and plasmapheresis was performed depending on the disease stage. 90 patients underwent surgery. Reconstruction in aorto-ileo-femoral zone was performed in 57 patients (in 34--with good results), in femoro-popliteo-femoral zone--in 33 patients (in 19--with good results). The "Gore-Tex" grafts were the plastic material for reconstruction, but autovein in situ was also used in femoro-popliteal zone.

Patients with suspected chronic stable angina can be evaluated in three stages. In stage one, the clinician uses information from the history, physical examination, laboratory tests for diabetes and hyperlipidemia, and resting electrocardiography to estimate the patient's probability of coronary artery disease (CAD). In stage two, additional testing for patients with a low probability of CAD focuses on diagnosing noncoronary causes of chest pain. Patients with a high probability of CAD have stress tests to assess their risk from CAD, and patients with an intermediate probability of CAD have stress tests to estimate the probability of CAD and assess their risk from CAD. Most patients with new-onset angina can start stress testing with exercise electrocardiography. The initial stress test should be a stress imaging procedure for patients with rest ST-segment depression greater than 1 mm, complete left bundle-branch block, ventricular paced rhythm, preexcitation syndrome, or previous revascularization with percutaneous coronary angioplasty or coronary artery bypass grafting. Patients who cannot exercise can have an imaging procedure with stress induced by pharmacologic agents. In stage three, patients with a predicted average annual cardiac mortality rate between 1% and 3% should have a stress imaging study or coronary angiography with left ventriculography. Those with a known left ventricular dysfunction should have cardiac catheterization. Patients with CAD who have an estimated annual mortality rate greater than 3% should have cardiac catheterization to determine whether their anatomy is suitable for revascularization. Patients with an estimated annual mortality rate less than 1% can begin to receive medical therapy.

In order to examine the relationship between depressive symptoms and the lipid metabolism in the elderly with hypertension, we recruited 311 outpatients aged 65 or older with hypertension and defined depression as patients with 6 or more symptoms on Geriatric Depression Scale short form. We further classified depressed patients into three groups: mild depressed with 6-7 symptoms, moderate depressed with 8-10 symptoms and severe depressed with 11 or more symptoms. Serum total cholesterol, serum HDL cholesterol and serum LDL cholesterol levels were significantly higher in female depressed patients than those in nondepressed patients (TC, 194.6 +/- 30.1 vs 208.0 +/- 32.8 p < 0.01; HDL, 67.3 +/- 19.3 vs 72.3 +/- 16.2 p < 0.01; LDL, 107.6 +/- 26.5 vs 116.0 +/- 29.1 p < 0.05). In male patients, serum lipids were not significantly associated with depressive symptoms but depressed patients were significantly older than nondepressed patients (75.3 +/- 6.2 vs 78.0 +/- 5.9 p < 0.05). Concerning the analysis of the severity of depression, serum total cholesterol and serum LDL cholesterol levels were significantly higher in mildly depressed patients than nondepressed patients in females and the same tendency was seen in male patients. No linear associations were shown between the severity of depression and serum lipids. We concluded that hyperlipidemia may be associated with depressive symptoms in elder patients with hypertension and that it might be related the severity of depression. We need to further investigate the relationship between depression and lipid metabolism in larger population samples.

35 patients with diabetes mellitus type 2 complicated with hyperlipidemia, coronary heart disease, were treated for 8 months with poseidonol which incorporates essential polyunsaturated fatty acids and fat-soluble vitamins. Poseidonol reduced atherogenic index from 4.2 to 3.15. The study of blood coagulation and fibrinolysis points to signs of hypocoagulation and normalization of fibrinolytic activity against previous hypercoagulation and fibrinolysis depression.

Hypothyroidism affects 4% to 10% of women, increasing with age. Symptoms, which are often nonspecific and subtle, can include: lethargy, mild weight gain, edema, cold intolerance, constipation, mental impairment, dry skin, depression, irregular menses, hoarseness, myalgias, hyperlipidemia, and bradycardia. TSH determination is usually warranted when some of these are present. Confirmation of diagnosis is based on laboratory tests, not symptoms. With Hashimoto's thyroiditis, the most common cause, the thyroid is usually firm and irregular to palpation. Screening is recommended by the American Thyroid Association, American Association of Clinical Endocrinologists and ACOG. Studies indicate that even slight hypothyroidism is associated with increased miscarriage, late fetal demise and lower IQ of offspring. Many believe all women intending conception or pregnancy should be screened. Most patients with even slightly elevated TSH should be treated, though controversy remains. Hypothyroidism is usually permanent, and treatment is life-long; postpartum thyroiditis may be transient. Levothyroxine is the standard treatment. Because of variable bioavailability of some levothyroxine preparations, designation of a specific high-quality brand is appropriate; TSH should be monitored to titrate the dose. The third-generation super-sensitive TSH is the most accurate test for both hypo- and hyperthyroidism. Because estrogen increases levels of thyroid binding globulin, women who are on HRT or OCs, or are pregnant, usually have total T4 levels above the reference range.

We have studied the effects of chronic treatment with cromakalim (75 ug kg(-1) per day) and glibenclamide (20 mg kg(-1) per day) in alloxan-induced diabetic rats. Injection of alloxan (60 mg kg(-1)/i.v., single dose) produced a significant increase in the blood pressure, bradycardia, hyperglycemia, hypoinsulinemia, hyperlipidemia, hypothyroidism and depression in left ventricular developed pressure (LVDP). While glibenclamide significantly prevented alloxan-induced hyperglycemia and hypoinsulinaemia, it failed to alter hypertension, bradycardia, hypertriglyceridaemia and hypercholesterolemia. Treatment with cromakalim-prevented hypertension and bradycardia, but not the hyperglycemia or hypoinsulinaemia. Co-administration of cromakalim with glibenclamide antagonized the effect of glibenclamide on these parameters. Cromakalim treatment also prevented alloxan-induced hypercholesterolemia and hypertriglyceridaemia. It also produced a significant increase in serum T(3) and T(4) levels. Glibenclamide did not significantly alter alloxan-induced hypothyroidism. In conclusion our data suggest that cromakalim and glibenclamide produce some metabolic effects that are either not related to K(ATP) channel modulation or may involve different sub-types of potassium channels. Further glibenclamide when combined with cromakalim may not be beneficial in a condition when diabetes mellitus and hypertension co-exits.
