Dyslipidemia of chronic renal failure is of multifactorial origin. Decreased activity of lipoprotein lipase and hepatic triglyceride lipase, peripheral insulin resistance, hyperparathyroidism and L-carnitine deficiency are the contributing factors. This results in a disturbed catabolism of chylomicron, accumulation of very-low-density (VLDL) and intermediate-density (IDL) lipoproteins as well as incompletely cleared remnant particles, whereas low-density lipoprotein (LDL) levels are diminished. There is current debate as to whether cardiovascular disease is accelerated and whether hyperlipidemia should specifically be treated. In addition, there have been few means of influencing these metabolic alterations. Drug incompatibility and consequently side effects render treatment difficult. The drugs that have been most tested for lipid lowering in chronic renal failure are the fibric acids. By their mode of action, they are the logical choice. Dose reduction overcomes major side effects such as myopathy and rhabdomyolysis. The second generation of fibric acid derivatives (gemfibrozil and beclobrate) show several advantages over formerly used derivatives. Treatment with lovastatin and simvastatin appears to be safe and is recommended in a minority of patients with predominantly elevations of LDL. HMG-CoA reductase inhibitors also lower remnant particles effectively in hemodialysis (HD) patients. L-Carnitine and low-molecular-weight heparin have been shown to influence VLDL rich in triglycerides in a subset of patients on HD. In posttransplant hyperlipidemia, diet remains the first course of action in all patients. When this approach fails, the new lipid-lowering agents, especially fibric acids, appear to be safe in short-term studies in azathioprine- and ciclosporin-treated patients. Lovastatin has been shown to be safe in stable renal transplant patients. Its toxicity seems to depend mainly on high ciclosporin whole blood through or plasma levels.

Obesity and its associated morbidities and mortalities are the effects of imbalance between energy intake and expenditure. The healthcare burden for the treatment of obesity is significantly high, due to increased risk of secondary chronic diseases such as hypertension and associated co-morbidities such as diabetes and cardiovascular disease. Lack of physical activity, high fat diets and sedentary life styles are major factors contributing to obesity. However, genetic predisposition and ethnicity are increasingly found to cause obesity. Till date, approved therapeutics have addressed excess energy intake by acting on central neural circuits that regulate feeding or on peripheral mechanisms to reduce nutrient absorption from the gut. These approaches have met with moderate success; and recently with safety concerns, leaving an unmet medical need for effective and safe pharmacotherapy for obesity thereby posing a significant challenge to pharmaceutical industry. Potential antiobesity drugs, which are being investigated by different companies, can be classified in 4 broad categories: 1) Agents that primarily decrease appetite through central action; 2) Agents that primarily increase metabolic rate or affect metabolism through peripheral action; 3) Agents that act on gastrointestinal tract; and 4) Agents that not only affect obesity but also overall Metabolic Syndrome. The current review will deal mainly with different molecules, which are under development for the above-mentioned targets and also their potential benefits and disadvantages.

Childhood and adolescence are crucial times for the development of a healthy skeletal and cardiovascular system. Disordered mineral and bone metabolism accompany chronic kidney disease (CKD) and present significant obstacles to optimal bone strength, final adult height, and cardiovascular health. Decreased activity of renal 1 alpha hydroxylase results in decreased intestinal calcium absorption, increased serum parathyroid hormone levels, and high-turnover renal osteodystrophy, with subsequent growth failure. Simultaneously, phosphorus retention exacerbates secondary hyperparathyroidism, and elevated levels contribute to cardiovascular disease. Treatment of hyperphosphatemia and secondary hyperparathyroidism improves growth and high-turnover bone disease. However, target ranges for serum calcium, phosphorus, and parathyroid hormone (PTH) levels vary according to stage of CKD. Since over-treatment may result in adynamic bone disease, growth failure, hypercalcemia, and progression of cardiovascular calcifications, therapy must be carefully adjusted to maintain optimal serum biochemical parameters according to stage of CKD. Newer therapeutic agents, including calcium-free phosphate binding agents and new vitamin D analogues, effectively suppress serum PTH levels while limiting intestinal calcium absorption and may provide future therapeutic alternatives for children with CKD.

Lack of physical activity in the general population is a public health problem and is recognized as an independent risk factor for the development of coronary disease. The relative risk of inactivity is similar to that of hypertension, hypercholesterolemia and smoking. Consequently, a sedentary lifestyle is associated with a concurrent increase in cardiovascular disease. Engaging regularly in mild-to-moderate physical exercise results in a range of physiological adaptations that are beneficial for health. Various studies have demonstrated that there is an inverse relationship between regular exercise and the risk of coronary heart disease, cardiac events and death. Exercise improves the lipid profile and glycemic control, reduces or prevents hypertension, obesity and stress, and promotes fitness and longevity. However, most evidence for the benefits of exercise comes from observational studies and, although maximum oxygen uptake and the duration of exercise on an exercise stress test are powerful predictors of mortality, there is no agreement on the quantity or intensity of the physical activity needed for primary or secondary prevention. On the other hand, although there is a temporarily increased risk of acute myocardial infarction during exhaustive exercise, the balance of risks and benefits is strongly in favor of the benefits because there is a minimum threshold for the weekly energy expenditure required to reduce cardiovascular risk.
