Landmark Five-Year African Study Indicates That HIV Therapy May Be Given Safely In Re-Limited Settings Without Routine Laboratory Monitoring
Gilead Sciences, Inc. (Nasdaq:GILD) highlighted results from a study known as DART (Development of Anti-Retroviral Treatment in Africa), which evaluated the need for routine laboratory monitoring in adults taking antiretroviral therapy in Africa. The DART trial was an open-label, randomized study comparing clinical and laboratory monitoring to clinical monitoring alone for efficacy and toxicity. In this study, 74 percent of patients were on a treatment regimen containing Viread® (tenofovir disoproxil fumarate). At baseline, more than 50 percent of patients had reduced renal function. The results indicated that Viread was well tolerated and that the incidence of renal adverse events was low. DART researchers concluded that renal function test results were similar in both arms of the trial for up to five years, suggesting that routine monitoring of Viread may not be necessary in re-limited settings when using the product as part of a first-line HIV treatment regimen. The results of the study were presented today at the 5th International AIDS Society Conference on HIV Pathogenesis, Treatment and Prevention (IAS 2009) in Cape Town, South Africa.

Early Detection Of Osteoarthritis In Dogs Could Open Doors For A Cure

Osteoarthritis is commonly diagnosed in the late and irreversible stages, when treatment can only be expected to decrease pain and slow progression of disease. Because osteoarthritis is a widespread problem in dogs, horses and humans, doctors and veterinarians need a precise way to diagnose the disease early and accurately. Now, University of Missouri researchers are investigating potential biomarkers in dogs for early diagnosis of osteoarthritis, which could help identify patients at increased risk of developing osteoarthritis. "By developing methods for earlier diagnosis of osteoarthritis, prevention or even curative treatment strategies to manage the disease become more realistic," said James Cook, professor of veterinary medicine and surgery, and the William & Kathryn Allen Distinguished Professor in Orthopedic Surgery. "Biomarkers could detect the disease before pain and swelling occurs, and owners could take preventative measures, such as modifying activities or diet, helping their pets lose weight and strengthen their joints, to reduce the likelihood of their dogs developing osteoarthritis." In the study, researchers examined potential biomarkers in synovial fluid. Synovial fluid, which is fluid that lubricates the joints, is known to have sensitive and rapid responses to joint injury. Taking samples from dogs, researchers found that synovial fluid quantity and quality were altered in injured stifle joints (the joint in the hind limbs of dogs that is the equivalent joint to the human knee). "At the MU Comparative Orthopaedic Laboratory, we are particularly interested in identification and validation of biomarkers that can detect early stages of osteoarthritis to provide accurate diagnostic and prognostic information prior to the onset of clinical disease for people and for pets," Cook said. "Our team, led by Drs. Kuroki, Stoker and Garner, is making tremendous progress in developing simple tests on blood, urine and synovial fluid that show great promise for helping us diagnose impending osteoarthritis before it is too late to help the patient in the most effective manner." Osteoarthritis causes degradation of articular cartilage, leading to pain, inflammation and loss of motion in the joint. Veterinarians predict that 20 percent of middle-aged dogs and 90 percent of older dogs have osteoarthritis in one or more joints and the percentages are even higher for the human population. The study, "Examination of Synovial Fluid Hyaluronan Quantity and Quality in Stifle Joints of Dogs with Osteoarthritis," was published in the American Journal of Veterinary Research. It was coauthored by Cook; Rachel Venable, doctoral student; Aaron Stoker, research assistant professor; Cristi Cook, clinical assistant professor; and Mary Cockrell, research specialist.
