• People who developed kidney or urinary tract stones were more likely to later experience bone fractures.
• The median time between diagnosis and bone fracture was 10 years
• Among patients with an autoimmune disease called ANCA-associated vasculitis, autoantibody increases were linked with an 11-fold increased risk of relapse in patients whose kidneys were affected.

Scientists speculate that the highest risk factor for a kidney disease common to five Balkan nations is a plant commonly used in various Chinese herbal medicines.
• Dialysis drives progressive white matter brain injury due to blood pressure instability; however, patients who dialyzed at 0.5◦C below body temperature were completely protected against such white matter changes.
• Among new dialysis patients, the most frequently cited concerns were that patients felt they were doing fine on dialysis and felt uncomfortable asking someone to donate a kidney.
• Older age was linked with having high health-related or psychosocial concerns, as was being a woman, being less educated, and having more comorbid illnesses.
• Patients having such concerns had less than half the chance of getting listed for a transplant than those without them.
Keryx Biopharmaceuticals, Inc. (Nasdaq:KERX) (the "Company") today announced that the U.S. Food and Drug Administration (FDA) approved Ferric Citrate (formerly known as Zerenex) for the control of serum phosphorus levels in patients with chronic kidney disease (CKD) on dialysis.

• Among patients with chronic kidney disease, the risks of developing kidney failure or dying prematurely increased markedly in a step-wise fashion after each successive hospitalization for heart failure.
• Calcium build-up in the coronary artery walls was more useful for correctly predicting kidney disease patients’ risk of heart disease than other measures of atherosclerosis such as thickness of the carotid artery walls and narrowing of the arteries in the legs.
Calcium buildup in the coronary arteries of chronic kidney disease patients may be a strong indicator of heart disease risk, according to a new study released in the Journal of the American Society of Nephrology (JASN). Researchers at the Johns Hopkins Bloomberg School of Public Health assert that coronary calcium outperforms two other commonly used measures of subclinical atherosclerosis in predicting the risk of heart disease among individuals with kidney disease.
The American Society of Nephrology (ASN) congratulates The New York Times for calling attention to transplant tourism and organ trafficking. Yet ASN is disappointed with the article’s characterization of dialysis and failure to address opportunities to improve this lifesaving therapy. ASN urges Congress to pass legislation to help transplant recipients and living donors.
• In 2 predominantly black dialysis clinics, women were less likely to want to undergo living donor kidney transplantation compared with men, despite being more likely than men to receive unsolicited offers for kidney transplants from family and friends.

The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
• Ferric citrate effectively reduced blood phosphorus levels while increasing iron stores and decreasing the need for intravenous iron and anemia medications in dialysis patients.
• The medication may help reduce complications and costs associated with kidney disease care.
• Among children with sporadic nephrotic syndrome, genetic mutations in the kidney’s filtration barrier were frequently linked with a lack of response to immunosuppressive treatments.
• The genetic test was even more predictive than a kidney biopsy for identifying children who would not benefit from immunosuppressive therapies.
Keryx Biopharmaceuticals, Inc. announced the publication of results from the long-term, randomized, active control Phase 3 study of Zerenex (ferric citrate), the Company's investigational oral ferric iron-based phosphate binder, for the treatment of hyperphosphatemia in patients with end-stage renal disease (ESRD) on dialysis. The PERFECTED study (PhosphatE binding and iRon delivery with FErric CiTrate in EsrD) was published online today in the Journal of the American Society of Nephrology (JASN).
• Between 1999 and 2010, lower income regions in the US consistently had lower rates of living donation compared with higher income populations.
• The difference in living donation rates between lower and higher income regions was much larger in recent years than it was in the past.
• The increased cost of an expensive drug that can prevent clots in dialysis catheters may be offset by lower costs for managing complications.
• Additional studies are needed to determine the medication’s long-term cost and effectiveness.
Researchers at the George Washington University were published in the New England Journal of Medicine, calling for greater follow-up care for those with acute kidney injury, as these patients often present later in life with chronic kidney disease, and vice versa.

The results of a 20-year study confirm that people with Type 1 diabetes who have developed kidney complications can slow the progress of their complications by improving control of their blood glucose over the long term. This finding may lead to changes in clinical practice for this population.
Developing therapies for kidney disease can be made faster by adopting a new, more sensitive definition of kidney disease progression, according to a study published by JAMA.
A new study led by researchers at the Johns Hopkins Bloomberg School of Public Health suggests that new therapies for kidney disease could be developed more quickly by revising the definition of kidney disease progression used during clinical trials. If adopted, the new definition could shorten the length of some clinical trials and also potentially encourage more clinical trials in kidney disease.

• Individuals with poor kidney function also had an increased risk of urothelial cancer
• Kidney function was not linked with risk for other cancers, including prostate, breast, lung, and colorectal cancers.

• Among patients with chronic kidney disease who were followed for an average of 1.3 years, those who walked for exercise were 33% less likely to die and 21% less likely to need dialysis or a kidney transplant.
• The more patients walked, the less likely they were to die or to need dialysis or a transplant.
• Simulation models predict that a newly approved kidney allocation policy will lead to an average 7.0% increase in median patient life-years per transplant and an average 2.8% increase in median allograft years of life.
• The policy may also improve access to transplantation for highly sensitized candidates but reduce access for older patients.
• Among kidney failure patients on dialysis who were treated in the hospital, one additional doctor visit in the month following hospital discharge was estimated to reduce the probability of 30-day hospital readmission by 3.5%.
• Seeing kidney failure patients one additional time in the month following discharge could save $240 million in health care costs each year.
