Iron Can Have Negative Side Effects On People With Kidney DiseaseJuly 30, 2004More than 20 million Americans- one in nine adults- have chronic kidney disease, and most don't even know it.[1] Physicians are constantly searching for the most effective therapies to help people with end-stage renal disease (ESRD), which occurs when kidney disease has progressed and about 90% of kidney function has been lost. While iron therapy is a common treatment for such patients, new evidence suggests that iron is potentially toxic and its long-term consequences are unknown. Given that intravenous iron can damage normal kidneys, its potential toxicity might be even greater in kidneys affected by disease. The journal Kidney International, published by Blackwell on behalf of the International Society of Nephrology, just released findings from an experimental study revealing that intravenous iron therapy administered to patients with kidney disease may have negative side effects. More clinical studies need to be performed to corroborate the findings. Dr. Richard Allen Zager, a prominent researcher who has served as a NIH funded investigator on kidney disease for the past 25 years, noted "This study will likely stimulate aggressive clinical investigation of the issues raised by the findings of this experimental paper." The study provides support for the concept that parenteral iron formulations are potentially toxic. Rather than helping patients, iron therapy may exacerbate progressive renal damage. Yet iron therapy remains essential in the treatment of patients with chronic kidney disease. This study points out that the level of toxicity depends on the nature of the iron formula given to patients. The four types of formulations-iron dextran (INFeD from Watson Pharmaceuticals), iron sucrose (Venofer from American Regent), iron gloconate (Ferrlecit from Watson Pharmaceutics) and Feoligosaccharide (FeOS, currently in clinical trials from Pharmacosmos) - are statistically different in their toxicity in this study. In highlighting the differences in toxicity among currently used iron replacement therapies, this study could ultimately impact drug selection by physicians. | |||||||||||||||||||||

University of Maryland researchers identify common gene variant linked to high blood pressure Researchers at the University of Maryland School of Medicine have identified a common gene variant that appears to influence people's risk of developing high blood pressure, according to the results of a study being published online Dec. 29, 2008 in the Proceedings of the National Academy of Sciences (PNAS). Simple Model Predicts Those at Risk for Chronic Kidney Disease Traditionally, doctors have had no clear way to predict which of their patients might be headed down the road to chronic kidney disease (CKD). Better patient outcomes with drug eluting stents Patients receiving drug eluting stents (DES) - stents coated with medication to prevent narrowing of the artery - as part of an angioplasty had better outcomes one year later than patients with bare metal stents, according to a new study to be published in CMAJ http://www.cmaj.ca/press/080050.pdf. Can you hear me now? How the inner ear's sensors are made A UCLA study shows for the first time how microscopic crystals form sound and gravity sensors inside the inner ear. Located at the ends of cilia - tiny cellular hairs in the ear that move and transmit signals - these crystals play an important role in detecting sound, maintaining balance and regulating movement. Preventing anemia is important to kidney disease patients' quality of life Maintaining sufficient red blood cell levels is important to the physical and mental health of patients with chronic kidney disease (CKD), according to a study appearing in the January 2009 issue of the Clinical Journal of the American Society Nephrology (CJASN). The findings indicate that preventing anemia in kidney disease patients should be an integral part of their care. African-American Canadians who receive kidney transplants fare better than those in US African American kidney disease patients in both Canada and the United States are less likely than Caucasian Americans to have access to kidney transplants, but only African-Americans in the United States have worse health outcomes than Caucasians after a transplant is performed. Scientists identify cell changes leading to impaired 'artificial kidney' function Molecular targets identified by a Spanish research team may hold the key to freedom for some sufferers of kidney disease. A new study published in Disease Models & Mechanisms (DMM), dmm.biologists.org, reveals the cellular signals which cause one treatment for kidney failure to lose its usefulness over time. A reversal of thinking: How women with lupus can increase chance for healthy pregnancies In the not so distant past, women with systemic lupus erythematosus (SLE), an autoimmune disease, were advised not to have children, and if they became pregnant, to have therapeutic abortions to prevent severe flares of their lupus. Larger labs report kidney function routinely Labs that conduct the highest number of routine blood tests are more likely than others to report estimated glomerular filtration rate (eGFR), an important measure of kidney function that can identify early kidney disease.
