After heart transplantation a number of factors such as pre- and postoperative hypoxia of the myocardium, myocardial failure of the early postoperative period, acute rejection episodes, cytomegalovirus infection, and finally the progressive atherosclerosis of the coronary arteries lead to the development of transplanted heart failure. Severe alterations of the myocardial function at this end stage of the process correspond to incurable cardiomyopathy. The target of plasmapheresis in this case is to decrease the extent of the disturbances in the lipoprotein contents and blood rheology for the improvement of the coronary perfusion of the transplanted heart. Nine patients with 3-7 year survival periods after heart transplantations underwent plasmapheresis twice a year using the Haemonetics PCS-plus machine. 2,100-2,700 ml of plasma was removed. Biochemical data, rheology and coagulation, and the concentration of Sandimmune (Sandoz Pharma Ltd., Basel, Switzerland) were controlled, and radionuclide scintigraphy of the myocardium, coronarographia, and transesophageal ultrasound investigations were completed for these patients. The result was the significant improvement of the coronary perfusion of the myocardium. The level of immunosuppression after the plasmapheresis procedures did not change and therefore did not demand any correction. Thus, we think that plasmapheresis can be an effective method of treatment of posttransplantation cardiomyopathy; the improvement of coronary perfusion decreases the extent of chronic ischemia. Further studies are necessary to answer the question as to whether it is possible to prolong the time before retransplantation with the help of plasmapheresis.

Plasma lipid levels are important risk factors for the development of atherosclerosis and coronary heart disease. Previous findings have shown that probiotic bacteria exert positive effects on hypercholesterolemia by lowering serum cholesterol and improving lipid profile that, in turn, leads to a reduced risk of coronary heart disease and atherosclerosis. Most of these studies were carried out with tumoral cell lines that have a metabolism quite different from that of normal cells and may thus respond differently to various stimuli. Here, we demonstrate the beneficial effects of some probiotics on cholesterol levels and pathways in normal small intestinal foetal epithelial tissue cells. The results show that Lactobacillus plantarum strain PCS 26 efficiently removes cholesterol from media, exhibits bile salt hydrolase activity, and up-regulates several genes involved in cholesterol metabolism. This study suggests that Lactobacillus plantarum PCS 26 might act as a liver X receptor agonist and help to improve lipid profiles in hypercholesterolemic patients or even dislipidemias in complex diseases such as the metabolic syndrome.

Dyslipidaemia is a critical risk factor for the development of cardiovascular complications such as ischemic heart disease and stroke. Although statins are effective anti-dyslipidemic drugs, their usage is fraught with issues such as failure of adequate lipid control in 30% of cases and intolerance in select patients. The limited potential of other alternatives such as fibrates, bile acid sequestrants and niacin has spurred the search for novel drug molecules with better efficacy and safety. CETP inhibitors such as evacetrapib and anacetrapib have shown promise in raising HDL besides LDL lowering property. Microsomal triglyceride transfer protein (MTP) inhibitors such as lomitapide and Apo CIII inhibitors such as mipomersen have recently been approved in Familial Hypercholesterolemia but experience in the non-familial setting is pretty much limited. One of the novel anti-dyslipidemic drugs which is greatly anticipated to make a mark in LDL-C control is the PCSK9 inhibitors. Some of the anti-dyslipidemic drugs which work by PCSK9 inhibition include evolocumab, alirocumab and ALN-PCS. Other approaches that are being given due consideration include farnesoid X receptor modulation and Lp-PLA2 inhibition. While it may not be an easy proposition to dismantle statins from their current position as a cholesterol reducing agent and as a drug to reduce coronary and cerebro-vascular atherosclerosis, our improved understanding of the disease and appropriate harnessing of resources using sound and robust technology could make rapid in-roads in our pursuit of the ideal anti-dyslipidemic drug.
