Statins linked to lower risk of infectionApril 06, 2007Markedly lower frequency of sepsis in dialysis patients observed Researchers at Johns Hopkins may have discovered an unintended benefit in the drugs millions of Americans take to lower their cholesterol: The medications, all statins, seem to lower the risk of a potentially lethal blood infection known as sepsis in patients on kidney dialysis. The study is published in the current issue of the Journal of the American Medical Association (JAMA). Sepsis is the leading cause of death in non-coronary intensive care units in the United States, according to the U.S. Centers for Disease Control. It also poses serious risk for kidney patients undergoing regular dialysis treatments. The Hopkins researchers cautioned that kidney dialysis patients should not necessarily ask their doctors to put them on statins until more studies are done to verify their findings. Building on earlier, limited studies that suggested risk reduction in animals and some people, Professor of Medicine, Director of the Welch Center and senior author Neil R. Powe, M.D., and his Johns Hopkins team followed 1041 dialysis patients for 10 years, dividing the subjects into those taking statins and those not. "Those taking statins had a 41 in a 1,000 chance of being hospitalized for sepsis, while the other group not taking statins had a 110 out of 1,000 risk. Although the overall absolute risk is relatively small, the statin group's risk is dramatically lower," says Rajesh Gupta M.D., the study's lead author, who was a senior medical resident at Hopkins when the study was conducted. Gupta says it remains unclear why or how statins work this way, "but the consistency of the findings with laboratory studies adds a lot of credence to the idea that statins are doing something substantial to reduce risk." "Statins are known to have an effect on the body's immune system, but what that is exactly, and how many statin users it affects, is still not widely understood." Statins may regulate the immune response to infection or fight microbes directly, Powe suspects. The study's authors also suppose that statins may work like penicillin, since the first statin was originally derived from a fungus which, it is theorized, secretes a statin as a way to starve other competing microorganisms that require cholesterol to survive. The study included patients from 81 dialysis clinics across 19 states. Only those enrollees who were admitted to the hospital with sepsis were counted, in order to rule out any subjects who became septic during an unrelated hospital stay. Only 14 percent of those initially enrolled in the study were on statins. Out of the 1,041 patients, there were a total of 303 hospitalizations for sepsis. Johns Hopkins Medical Institutions |

Researchers mobilizing global resources to test new treatments for severe H1N1 infection An important, ground-breaking initiative is unfolding in the global critical care community in response to the H1N1 pandemic. Widely used cholesterol-lowering drug may prevent progression Simvastatin, a commonly used, cholesterol-lowering drug, may prevent Parkinson's disease from progressing further. Neurological researchers at Rush University Medical Center conducted a study examining the use of the FDA-approved medication in mice with Parkinson's disease and found that the drug successfully reverses the biochemical, cellular and anatomical changes caused by the disease. Statins show dramatic drug and cell dependent effects in the brain Besides their tremendous value in treating high cholesterol and lowering the risk of heart disease, statins have also been reported to potentially lower the risks of other diseases, such as dementia. Cholesterol-lowering medicines may be effective against cancer Statins lower cholesterol by blocking certain enzymes involved in our metabolism. Adding ezetimibe to atorvastatin improves lipid control Adding ezetimibe to atorvastatin significantly boosted the attainment of lipid targets as specified by both Canadian and European guidelines in elderly patients aged 65 and older and the combination produced superior results than simply increasing the dose of atorvastatin alone. Use of statins favors the wealthy, creating new social disparities in cholesterol Since the introduction of statins to treat high cholesterol, the decline in lipid levels experienced by the wealthy has been double that experienced by the poor. Women with Atrial Fibrillation Are at Significantly Higher Risk of Stroke and Death Compared to Men and Receive Less Attention Even though the incidence of atrial fibrillation is higher in men than women, a review of past studies and medical literature completed by cardiac experts at Rush University Medical Center shows that women are more likely than men to experience symptomatic attacks, a higher frequency of recurrences, and significantly higher heart rates during atrial fibrillation, which increases the risk of stroke. Pre-hospital organization: The first links in the chain of survival for heart attack patients Mortality rate following a heart attack has fallen by more than 50% in Europe over the past 25 years. However, because only minor advances in the medical treatment of AMI are expected over the next decade, it is through organisational changes in the pre-hospital phase that mortality rate will continue this decline to below 5%. Fatostatin' is a turnoff for fat genes A small molecule earlier found to have both anti-fat and anti-cancer abilities works as a literal turnoff for fat-making genes, according to a new report in the August 28th issue of the journal Chemistry and Biology, a Cell Press journal.
