Adiposopathy, metabolic syndrome, quantum physics, general relativity, chaos and the Theory of Everything.

Excessive fat (adiposity) and dysfunctional fat (adiposopathy) constitute the most common worldwide epidemics of our time -- and perhaps of all time. Ongoing efforts to explain how the micro (adipocyte) and macro (body organ) biologic systems interact through function and dysfunction in promoting Type 2 diabetes mellitus, hypertension and dyslipidemia are not unlike the mechanistic and philosophical thinking processes involved in reconciling the micro (quantum physics) and macro (general relativity) theories in physics. Currently, the term metabolic syndrome refers to a constellation of consequences often associated with excess body fat and is an attempt to unify the associations known to exist between the four fundamental metabolic diseases of obesity, hyperglycemia (including Type 2 diabetes mellitus), hypertension and dyslipidemia.

Adiposopathy: sick fat causes high blood sugar, high blood pressure and dyslipidemia.

Adiposopathy is defined as pathological adipose tissue function that may be promoted and exacerbated by fat accumulation (adiposity) and sedentary lifestyle in genetically susceptible patients. Adiposopathy is a root cause of some of the most common metabolic diseases observed in clinical practice, including Type 2 diabetes mellitus, hypertension and dyslipidemia. The most common term for the metabolic consequences of adiposopathy is currently 'the metabolic syndrome'.

Pharmacotherapy for dyslipidaemia--current therapies and future agents.

Current lipid-altering agents that lower low density lipoprotein cholesterol (LDL-C) primarily through increased hepatic LDL receptor activity include statins, bile acid sequestrants/resins and cholesterol absorption inhibitors such as ezetimibe, plant stanols/sterols, polyphenols, as well as nutraceuticals such as oat bran, psyllium and soy proteins; those currently in development include newer statins, phytostanol analogues, squalene synthase inhibitors, bile acid transport inhibitors and SREBP cleavage-activating protein (SCAP) activating ligands. Other current agents that affect lipid metabolism include nicotinic acid (niacin), acipimox, high-dose fish oils, antioxidants and policosanol, whilst those in development include microsomal triglyceride transfer protein (MTP) inhibitors, acylcoenzyme A: cholesterol acyltransferase (ACAT) inhibitors, gemcabene, lifibrol, pantothenic acid analogues, nicotinic acid-receptor agonists, anti-inflammatory agents (such as Lp-PLA(2) antagonists and AGI1067) and functional oils. Current agents that affect nuclear receptors include PPAR-alpha and -gamma agonists, while in development are newer PPAR-alpha, -gamma and -delta agonists, as well as dual PPAR-alpha/gamma and 'pan' PPAR-alpha/gamma/delta agonists.

Effects of simvastatin on C-reactive protein in mixed hyperlipidemic and hypertriglyceridemic patients.

This study examined the effects of simvastatin on C-reactive protein (CRP) and other inflammatory markers in study subjects with significant elevations in triglyceride (TG) blood levels. CRP, vascular cellular adhesion molecule (VCAM), serum amyloid A (SAA), and interleukin 6 (IL-6) were measured in archived plasma samples from 2 multicenter, randomized, double-blind, placebo-controlled studies designed to examine the lipid-altering efficacy of simvastatin in study subjects with elevated TGs. In the first study, 130 study subjects with mixed hyperlipidemia (low-density lipoprotein [LDL] cholesterol > or =130 mg/dl; TGs 300 to 700 mg/dl) received placebo or simvastatin 40 or 80 mg once daily for three 6-week periods in a complete-block crossover design.

Anti-obesity drug development.

Obesity accelerates morbidity and mortality and has been described by the World Health Organization (WHO) as an epidemic in many industrialised nations [101,102]. Diet, exercise and lifestyle recommendations have proven to be mostly ineffective in adequately preventing or treating the progression of this public health disease. Existing drug treatment is limited by the scarce number of safe and well-tolerated drugs with proven long-term efficacy in maintaining weight loss.
