Despite significantly raising HDL, torcetrapib failed to slow the progression of coronary plaques

Investigators reported today at the American College of Cardiology's 56th Annual Scientific Session that torcetrapib, a drug that substantially raises high-density lipoprotein cholesterol or HDL (the "good" cholesterol), did not slow the progression of plaque buildup in the coronary arteries as measured using an ultrasound probe (IVUS).

1. Combination HDL/LDL therapy has no effect on plaque build-up
   03-26-2007 · EurekAlert!
   Two RADIANCE studies presented today at the American College of Cardiology's 56th Annual Scientific Session assessed the effects of adding torcetrapib to atorvastatin among patients to improve their cholesterol levels. Although the ILLUMINATE study and other trials involving torcetrapib were recently stopped because of safety concerns, the effect of the drug on carotid intima-media thickness (CIMT) may provide useful information on whether it slows the progression of atherosclerosis.

2. Drug that mimics 'good' cholesterol has mixed effect on coronary atherosclerosis
   03-26-2007 · EurekAlert!
   The results of a study presented today at the American College of Cardiology’s 56th Annual Scientific Session showed that CSL-111, a drug that mimics HDL, did not significantly reduce plaque in coronary arteries in patients with a recent episode of ACS. However, patients taking the drug showed improvement in two indexes that assess changes in the blood vessels.

4. Interferon does not slow or stop hepatitis C from worsening, study finds
   11-08-2007 · EurekAlert!
   Interferon does not slow or halt the progression of chronic hepatitis C and advanced liver disease in patients who haven't responded to previous attempts to eradicate the disease, a national study has found. Patients who were treated with interferon did experience a significant decrease in viral levels and liver inflammation, but the trial unequivocally demonstrated that treatment with interferon does not prevent the worsening of liver disease in patients who've failed prior treatments.

   03-22-2007 · EurekAlert!
   Scientists at the University of Texas Medical Branch at Galveston and Neurobiotex, Inc. have found high levels of zinc in amyloid plaque deposits in the eye that are an indication of age-related macular degeneration (AMD). The discovery marks an additional similarity between AMD plaques and those seen in Alzheimer's disease and could facilitate the development of effective treatments for AMD.

   Eating fewer refined carbohydrates may slow the progression of age-related macular degeneration and ease the growing public health burden due to vision loss, report Tufts researchers. People who consumed the most refined carbohydrates were 17 percent more likely to develop blinding AMD than those who consumed the least.

10. Key to longer life (in flies) lies in just 14 brain cells
    09-20-2007 · EurekAlert!
    Fruit flies live significantly longer when the activity of the protein p53 is reduced in just 14 insulin-producing cells in their brains, new Brown University research shows. The results put scientists one step closer to understanding caloric restriction, a biochemical process proven to slow aging. Results appear in the Proceedings of the National Academy of Sciences.
