By Ann Gerhardt, MD Subscribe to DrG'sMediSense at drgsmedisense ; Bottom line at the top: Red yeast rice works at least as well as purified statin drugs to improve serum lipid levels. Don't imagine that it accomplishes this by harmless magic: It contains lovastatin brand name Mevacor ; and other chemically active substances that require medical monitoring. Think of it as drug. What it is: Rice fermented by the mold Monascus purpureus is known as red yeast rice. The fermentation product contains monacolins, which lower cholesterol. Monacolin K, one of the active components of red yeast rice, is produced by all Monascus species and some other molds. Other names for the same chemical structure are mevinolin and lovastatin brand name Mevacor ; , the first FDA-approved statin drug. In the 1990's Merck, Sharp & Dohme researchers identified the chemical structure of monacolin K, calling it lovastatin, and revolutionized pharmacologic cholesterol control. Compactin, a similar compound isolated from Penicillium molds, induces excessive toxicity in humans, but its chemically modified forms Zocor and Pravachol ; have been safe, effective and lucrative products for the pharmaceutical industry. The biggest money-maker of all, Lipitor, has an entirely synthetic structure based on the monocolins. The Chinese have used red yeast rice since the Tang dynasty as an ingredient in rice wine, as a coloring the red color of Peking duck ; and flavoring agent and as an herb to treat indigestion, diarrhea and circulatory disorders. Why it works: After conversion in the liver to the active form, all of the various monocolins and statin drugs inhibit the enzyme HMG CoA reductase, the first step of cholesterol synthesis in the human liver. Blocking this enzyme turns off the body's cholesterol production and induces the liver to pull more cholesterol out of the blood stream, thus lowering cholesterol levels in two ways. More potent than Mevacor: Red yeast rice lowers LDL-cholesterol the bad one ; more than an equivalent dose of lovastatin. In studies of patients taking standard doses of red yeast rice, LDL-cholesterol dropped by.

The Task Force would like to extend thanks to the pharmacists of the province for the great support and interest they have shown in the pilot project. Pharmacists in a number of health districts have communicated with their colleagues and submitted an application to participate. Others have voiced personal interest in the project and a need for the Task Force to help them to coordinate within their district, and still others have asked for additional information before they can commit to participating. We would like to take this opportunity to provide information on the pilot project itself and to share with you the progress to date and thioridazine. The Phytohealth project brings together scientists, nutritionists, clinicians, as well as large and small companies involved in the field of phytoestrogens. It is funded by the EU under the 5th Framework Programme. Phytohealth was formed to build consensus, share research and advise on future research on the topic of phytoestrogens and human health. The project was started in late 2003 and will continue for 3 years, during which time it will organise 3 plenary meetings and 3 platform meetings. At the 2nd plenary meeting to be held in Heraklion in October 2004, 3 European consensus papers will be officially presented on: Health effects of phytoestrogens; Safe and efficacious doses; and Assays for the evaluation of potency. These 3 consensus papers will be finalised by all who attend the meeting. Phytohealth needs active contributions from consumers, scientists and industry to really make an impact in establishing the health efficacy, safety, and optimal formulation of products from these plantderived molecules.

Intraocular inflammatory diseases are a common cause of severe visual impairment and blindness. In an acute mouse model of autoimmune retinal disease, we demonstrate that treatment with the 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor, lovastatin, suppresses clinical ocular pathology, retinal vascular leakage, and leukocytic infiltration into the retina. Efficacy was reversed by coadministration of mevalonolactone, the downstream product of 3-hydroxy-3-methylglutaryl coenzyme A reductase, but not by squalene, which is distal to isoprenoid pyrophosphate metabolites within the cholesterol biosynthetic pathway. Oovastatin treatment 20 mg kg day i.p. ; over 7 days, which resulted in plasma lovastatin hydroxyacid concentrations of 0.098 0.03 M, did not induce splenocyte Th2 cytokine production but did cause a small reduction in Ag-induced T cell proliferation and a decrease in the production of IFN- and IL-10. Thus, it is possible to dissociate the therapeutic effect of statins in experimental autoimmune uveitic mice from their activity on the Th1 Th2 balance. Statins inhibit isoprenoid pyrophosphate synthesis, precursors required for the prenylation and posttranslational activation of Rho GTPase, a key molecule in the endothelial ICAM1-mediated pathway that facilitates lymphocyte migration. Consistent with inhibition of leukocyte infiltration in vivo, lovastatin treatment of retinal endothelial cell monolayers in vitro leads to inhibition of lymphocyte transmigration, which may, in part, account for drug efficacy. Unlike lovastatin, atorvastatin treatment showed little efficacy in retinal inflammatory disease despite showing significant clinical benefit in experimental autoimmune encephalomyelitis. These data highlight the potential differential activity of statins in different inflammatory conditions and their possible therapeutic use for the treatment of human posterior uveitis. The Journal of Immunology, 2005, 174: 23272335. ntraocular inflammatory diseases are a major cause of severe visual impairment accounting for 10% of blind registrations in the working population 1 ; . These uveitic syndromes may occur as organ-specific auto ; immune diseases, such as pars planitis, sympathetic ophthalmia, and idiopathic posterior uveitis, or as part of a systemic immune-mediated disease such as Behcet's disease and sarcoidosis. 3-Hydroxy-3-methylglutaryl coenzyme A HMG-CoA ; 4 reductase inhibitors, generically termed statins, are widely prescribed for their cholesterol-lowering properties, but they also possess immunomodulatory activity. Indeed, substantive evidence has recently been presented demonstrating their efficacy in the treatment of autoimmune disease, notably in a model of multiple sclerosis and mexitil.
Patients may not qualify for lvrs if they have severe medical conditions that limit their lifespan; psychological problems; recent tobacco, drug, or alcohol dependence; chest wall deformity; corticosteroid dependence; or scarring around the membrane of the lung, for example, use of lovastatin.
