Scientists Identify Gene Responsible For Statin-induced Muscle Pain

Statins, the popular class of drugs used to lower cholesterol, are among the most commonly prescribed medications in developed countries. But for some patients, accompanying side effects of muscle weakness and pain become chronic problems and, in rare cases, can escalate to debilitating and even life-threatening damage.Now a study led by investigators at Beth Israel Deaconess Medical Center (BIDMC), helps explain the source of these problems.

NICE Publishes Guidance On EZETROL (Ezetimibe) For The Treatment Of Adults With Primary Hypercholesterolemia, UK

The National Institute for Health and Clinical Excellence (NICE) has published Guidance recommending that adding EZETROL(R) (ezetimibe) to initial statin therapy is a treatment option for patients whose cholesterol is not appropriately controlled on the initial statin, after appropriate dose titration (according to national targets), when consideration is being given to changing from initial statin therapy to an alternative statin.

Chlamydia pneumoniae involved in heart disease

… he has identified how two different kinds of Chlamydia can cause both coronary artery disease and miscarriages. Solving one mystery gave him clues that he needed to figure out the other. By focusing on the immune system mechanisms in Chlamydia infections, Azenabor has identified an important link in seemingly unrelated health problems. The result could be new treatments and prevention strategies for both heart disease and infertility. Chlamydia pneumoniae is a microbe that normally causes pneumonia and bronchitis, but it has long been associated with atherosclerosis, a cardiovascular disease also called “hardening of the arteries.”
Huh? Chlamydia? Yes, when the macrophages’ cell walls are infected with the C. pneumoniae their usually tight cholesterol, which they regularly store, traffics that cholesterol into the cell membrane’s and cause them to become rigid and unable to move…
The bacteria also “hijacks” the cells signaling in a way that helps promote the existence of the Chlamydia pneumoniae. The bacterium also disturbs the macrophage’s production of toxins in a process that transforms them into “signaling molecules,” which support functions that keep the bacterium alive. Because of this the bacteria can very quickly reproduce and accumulate in the blood vessels causing stiffening and heart disease, ie. atherosclerosis.

Study Focuses On The Side Effects Of Statins

Statins are a popular class of drugs used to successfully combat high cholesterol. However, the rare, but serious, and poorly understood side effect of skeletal muscle breakdown (a process known as atrophy) prevents more prevalent use of these drugs. New insight into the mechanism of statin-induced skeletal muscle atrophy has been provided by reserachers at Beth Israel Deaconess Medical Center, Boston.

Cholesterol Drug Linked To Sleep Problems

US researchers reported to a meeting of the American Heart Association’s Scientific Sessions 2007 this week that simvastain, a drug designed to lower cholesterol, could be the cause of disrupted sleep in some patients.Previous research, using small studies, has found that some patients taking cholesterol lowering statins slept badly and even had nightmares.

Lipitor Provides Greater Benefit Compared To Simvastatin In Patients With A History Of Heart Attacks Who Have Had Subsequent Cardiovascular Events

Pfizer announced that Lipitor(R) (atorvastatin calcium) Tablets (80 mg) was more effective than simvastatin (20 mg-40 mg) in reducing the risk of multiple cardiovascular events in patients with a history of heart attacks in the Incremental Decreases through Aggressive Lipid Lowering (IDEAL) clinical trial. Cardiovascular events included heart attack, stroke, and cardiac revascularization procedures such as bypass surgery and angioplasty.

Relationship Between Statins And Cognitive Decline More Complex Than Thought

Previous explorations of a link between statins, a cholesterol lowering medication, and cognitive decline have produced inconsistent results. New research reveals that the relationship between statin use and cognitive decline appears even more complex than had been thought. In a three year epidemiological study, researchers from the Indiana University School of Medicine and the Regenstrief Institute, Inc.
