Nine consecutive patients who underwent syringe-assisted liposuction with a mean aspirate volume of 3633 mL (range: 1800-5500) had their lipids, lipoproteins, and sex hormones measured pre- and postoperatively. Seven of the patients also underwent an oral glucose tolerance test with measurements of insulin and C-peptide. The major finding was a significant increase in HDL cholesterol and apolipoprotein A1, while there was no significant change in sex hormones or glucose levels 9-12 months after the liposuction procedure. The results indicate that large-volume liposuction might decrease the risk of cardiovascular disease in these patients.
1. Circulating catecholamines and dopamine-beta-hydroxylase (DbetaH) have been studied in a child with bilateral phaeochromocytoma. 2. Venous catheterization showed a great increase in catecholamine efflux from the left adrenal vein while DbetaH activity in the latter was only slightly elevated. 3. Circulating catecholamines fluctated greatly while DbetaH activity decreased gradually during the removal of the tumours. 4. Post-operatively, circulating catecholamines declined to normal values while DbetaH activity returned to pre-operative levels. 5. It is concluded that these tumours released circulating catecholamines independent of an exocytotic secretion of DbetaH and that the circulating DbetaH reflected the activity of the sympathetic nervous system.
The present study was performed to determine the influence of pharmaceutical intervention on parameters of blood coagulation and fibrinolysis in hypercholesterolemic patients. Eighteen otherwise-healthy individuals with heterozygous familial hypercholesterolemia were treated with a 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor (simvastatin, 40 mg daily) for 12-14 weeks followed by additional treatment with omega-3 fatty acids (equivalent to 4 g eicosapentaenoic acid/docosahexaenoic acid daily) for 6 more weeks. With simvastatin treatment, the mean decreases in total cholesterol, low density lipoprotein (LDL) cholesterol, and apolipoprotein B (apo B) were 39%, 46%, and 36%, respectively. Only minor changes in high density lipoprotein (HDL) cholesterol and apo A-1 were recorded. omega-3 fatty acids had minor additional effects. The most prominent effects on the blood coagulation system were the changes in extrinsic pathway inhibitor (EPI), which is the inhibitor of the factor VIIa-tissue thromboplastin complex. EPI activity decreased from a median of 153% to 111% (p less than 0.001) with simvastatin treatment and to 112% (p less than 0.001) on the combined regimen. EPI activity was significantly correlated with LDL cholesterol (r = 0.78), total cholesterol (r = 0.77), apo B (r = 0.65), and apo A-1 (r = 0.45). Multiple stepwise regression analysis showed that LDL cholesterol was the most important predictor of EPI activity, which suggests that a majority of EPI activity in plasma is associated with LDL. Moreover, the alteration in EPI activity was correlated closely with the corresponding alteration in LDL, which suggests a direct relation between a coagulation-inhibitor activity and a pharmaceutical lipid-related response.(ABSTRACT TRUNCATED AT 250 WORDS)
This study examined the action of cerivastatin, a new statin, in subjects with primary hypercholesterolaemia. The effects of two oral doses of cerivastatin (400 micrograms/day or 300 micrograms/day) were compared with placebo in 349 patients using a multicentre, randomized, double-blind, placebo-controlled study design. Cerivastatin treatment lasted 8 weeks and produced significant reductions in low density lipoprotein-cholesterol (LDL-C) levels from baseline compared with placebo. The reduction in LDL-C was significantly greater with 400 micrograms than with 300 micrograms cerivastatin. When responder rates were examined, the higher (400 micrograms/day) cerivastatin dose was found to be more effective in producing larger (> 40%) reductions in LDL-C levels. Cerivastatin treatment was well tolerated. Only two withdrawals due to adverse events during active treatment occurred, neither of which was considered to be due to the study medication. In addition, no clinically relevant increases in the levels of creatine phosphokinase and hepatic transaminases (alanine transaminase and aspartate transaminase) compared with placebo were seen in this study. In conclusion, cerivastatin treatment produced a significant lowering of LDL-C levels, with the higher dose providing the greatest benefit.
