Previously, genetics was considered the leading reason blacks are four times more likely to progress to end stage renal disease than whites and have much higher rates of cardiovascular disease and mortality in early chronic kidney disease (CKD). http://phys.org/news203879523.html Medicine & Health Thu, 16 Sep 2010 18:12:14 EST news203879523 On average, a lower blood pressure goal was no better than the standard blood pressure goal at slowing progression of kidney disease among African-Americans who had chronic kidney disease resulting from high blood pressure, according to results of the African-American Study of Kidney Disease and Hypertension (AASK), the largest and longest study of chronic kidney disease (CKD) in African-Americans. However, the blood pressure goal did benefit people who also had protein in the urine, which is a sign of kidney damage. The study, funded by the National Institutes of Health, appears in the Sept. 2 issue of the New England Journal of Medicine. http://phys.org/news202581275.html Medicine & Health Wed, 01 Sep 2010 18:10:05 EST news202581275 A study published Online First in The Lancet has identified a genetic mutation in the immune system which leads to chronic kidney disease in those affected. Furthermore, all the families affected so far are of Cypriot origin and the researchers believe this mutation represents a significant proportion of the kidney disease burden in Cyprus and in Cypriot families worldwide -- and that the mutation dates back to a single common ancestor at least 16 generations ago. http://phys.org/news201958192.html Medicine & Health Wed, 25 Aug 2010 18:30:01 EST news201958192 Millions of Americans in the early stages of chronic kidney disease (CKD) are at an increased risk of having atrial fibrillation (AF) - a major risk factor for stroke - according to new research by investigators at Wake Forest University Baptist Medical Center. http://phys.org/news199550776.html Medicine & Health Wed, 28 Jul 2010 16:00:01 EST news199550776 Discontinuing the anemia drug epoetin may be more effective than reducing the dose for normalizing potentially dangerous high hemoglobin levels in hemodialysis patients, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN). The results provide useful information about the balance required between administering epoetin and achieving target hemoglobin levels. http://phys.org/news199008217.html Medicine & Health Thu, 22 Jul 2010 17:00:09 EST news199008217 Regardless of demographics, African American patients with hypertensive nephrosclerosis have a higher rate of developing end stage renal disease (ESRD) than dying prematurely, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). Earlier studies showed patients of all races with Chronic Kidney Disease (CKD) were at greater risk of dying prematurely from cardiovascular disease (CVD) than reaching ESRD. http://phys.org/news199008438.html Medicine & Health Thu, 22 Jul 2010 17:00:02 EST news199008438 (PhysOrg.com) -- The results of a world-first controlled trial of dialysis start-time in patients with Stage V chronic kidney disease is set to have major impact on the cost and infrastructure of chronic kidney disease (CKD) treatment and dialysis services. http://phys.org/news198926165.html Medicine & Health Wed, 21 Jul 2010 10:30:03 EST news198926165 Individuals with a high resting heart rate and a low beat-to-beat heart rate variability have an increased risk of developing kidney disease, according to a study appearing in an upcoming issue of the Journal of the American Society Nephrology (JASN).

This analysis of 21 studies from 14 countries found that a common blood test to estimate kidney function and a urine test measuring protein (albumin) to estimate kidney damage were strongly related to mortality risk. The results are published in the May 17, 2010 issue of the Lancet. http://phys.org/news193320056.html Medicine & Health Mon, 17 May 2010 18:30:03 EST news193320056 A meta-analysis of more than a million people in populations across Europe, the USA, Australia, and Asia has shown that both glomerular filtration rate (GFR) (the rate at which blood is filtered by the kidneys) and levels of protein in urine (albuminuria) independently predict the risk of death in the general population. The findings appear in an Online First Article, written by Dr Josef Coresh, Johns Hopkins Bloomberg School of Public Health, Baltimore, MD, USA; Dr. Paul E de Jong, University Medical Center Groningen, Groningen, Netherlands; and Dr. Andrew Levey, Tufts Medical Center, Boston, and other colleagues from the Chronic Kidney Disease Prognosis Consortium. http://phys.org/news193320104.html Medicine & Health Mon, 17 May 2010 18:30:01 EST news193320104 Despite the very high rate of problems with sexual function among people with chronic kidney disease (CKD), little is known about the best treatment approaches in this group of patients, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN). http://phys.org/news192990422.html Medicine & Health Thu, 13 May 2010 17:27:49 EST news192990422 Healthy people with high blood pressure who excrete a slight excess of protein in the urine raise their risk of developing kidney and heart complications. According to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN), more attention should focus on the potential health effects of urinary protein excretion in individuals with high blood pressure (hypertension). http://phys.org/news191781180.html Medicine & Health Thu, 29 Apr 2010 18:10:01 EST news191781180 Black children with chronic kidney disease have more severe anemia than white children even when they receive the same treatment, according to a multicenter study led by Johns Hopkins Children's Center to be published in the May issue of the American Journal of Kidney Disease. http://phys.org/news191570496.html Medicine & Health Tue, 27 Apr 2010 07:20:01 EST news191570496 Here's another reason to kick the soda habit. New research published online in the FASEB Journal shows that high levels of phosphates may add more "pop" to sodas and processed foods than once thought. That's because researchers found that the high levels of phosphates accelerate signs of aging. High phosphate levels may also increase the prevalence and severity of age-related complications, such as chronic kidney disease and cardiovascular calcification, and can also induce severe muscle and skin atrophy. http://phys.org/news191515327.html Medicine & Health Mon, 26 Apr 2010 15:50:08 EST news191515327 The routine use of a screening urine dipstick to diagnose chronic kidney disease in healthy children is not a cost-effective test, confirm Penn State College of Medicine researchers, who validated an American Academy of Pediatrics (AAP) recommendation. http://phys.org/news190556537.html Medicine & Health Thu, 15 Apr 2010 13:22:31 EST news190556537 A team of researchers from the United States and Europe has identified more than a dozen genes that may play a role in the etiology of common forms of kidney disease. The team, known as the CKDGen Consortium, examined common variations in DNA sequences in more than 65,000 individuals of European descent. Common variations in several genes were found to be more frequent among people with poor kidney function or chronic kidney disease than in those with normal kidney function. The researchers further confirmed their findings in more than 20,000 additional individuals. The findings are published in the April 11 edition of Nature Genetics. http://phys.org/news190308071.html Medicine & Health Mon, 12 Apr 2010 16:21:30 EST news190308071 Kidney damage associated with chronic reflux is the fourth leading cause of chronic kidney disease and is the most common cause of severe hypertension in children. Doctors and researchers at Nationwide Children's Hospital have developed a new mouse model of vesicoureteral reflux (VUR), a common childhood condition that can lead to chronic kidney disease in children. http://phys.org/news189947503.html Medicine & Health Thu, 08 Apr 2010 12:50:08 EST news189947503 Millions of Americans may have chronic kidney disease (CKD) and not know it, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN). http://phys.org/news188763428.html Medicine & Health Thu, 25 Mar 2010 19:50:02 EST news188763428 With a concern that the automatic reporting of estimated glomerular filtration rate (GFR; the flow rate of filtered fluid through the kidney, which is used to define the stage and severity of chronic kidney disease) may result in unnecessary referrals by physicians, new research indicates that automated laboratory reporting was associated with a significant increase in first-time visits to a kidney specialist, particularly among those at increased risk of late detection of kidney disease (such as older or female patients), according to a study in the March 24/31 issue of JAMA. http://phys.org/news188581424.html Medicine & Health Tue, 23 Mar 2010 17:20:01 EST news188581424
