• Compared with standard dialysis, frequent dialysis can cause complications related to repeated access to the blood.
• The findings provide valuable information for dialysis patients and their physicians.
Acute kidney injury strikes large numbers of hospitalized patients, including those with no prior kidney-related illness, and is one of the most costly and deadly conditions affecting critically ill patients. Findings published today in Critical Care from a Mayo Clinic-led, multicenter study identify two biomarkers of acute kidney injury that can be easily measured in urine and detect affected patients roughly 12 to 36 hours earlier than current tests.
A new study from the Johns Hopkins Bloomberg School of Public Health and the Chronic Kidney Disease Prognosis Consortium (CKD-PC) found that in general chronic kidney disease is similarly associated with a higher risk of death and end stage renal disease for both women and men. The findings were released online in advance of publication in BMJ.
• Among people without diabetes or kidney disease, 10-year mortality was 7.7%.
• Among individuals with diabetes but without kidney disease, mortality was 11.5%.
• Among those with both diabetes and kidney disease, mortality was 31.1%.
• Residence in areas with higher average household income was linked with improved survival in kidney failure patients.

• Retention of certain compounds that are normally excreted by the kidneys may cause insulin resistance, or prediabetes, in kidney disease patients.
• When mice with kidney disease were treated with a prebiotic that reduces blood levels of these compounds, insulin resistance and lipid abnormalities were prevented.
• Six months of steroid treatment in children with nephrotic syndrome did not reduce relapse rates or side effects compared with three months of treatment.
• Because many children with nephrotic syndrome face frequent relapses, future research should focus on preventing relapses through new treatment strategies.
Nephrotic syndrome has an estimated incidence of two to seven cases per 100,000 children and a prevalence of nearly 16 cases per 100,000.
• Blocking the receptor for endothelin lowers novel cardiovascular risk factors in patients with chronic kidney disease independent of blood pressure.
• The findings suggest that blocking the receptor may provide heart-related benefits to these patients.
60 million people globally have chronic kidney disease.
• In a study of African Americans with kidney disease, levels of mineral metabolites rose over time; those with faster rates of kidney function decline had the greatest increases in metabolites.
• Higher baseline levels of metabolites were linked with an increased risk for kidney failure or death independent of kidney function.
Disordered mineral metabolism is more severe in African Americans with chronic kidney disease, which might partially explain why their disease progresses more rapidly to kidney failure.
Severe acute kidney injuries are becoming more common in the United States, rising 10 percent per year and doubling over the last decade, according to a retrospective study at the University of California, San Francisco (UCSF).
Kidney disease is on the rise across the global, and it’s becoming common among veterans considering their older age and rates of diabetes, high blood pressure and cardiovascular disease. Is the Department of Veterans Affairs prepared to handle their potential need for dialysis and kidney transplants and can anything be done to prevent a rise in kidney failure?
The University of Michigan will create a National Kidney Disease Registry for the Department of Veterans Affairs to monitor kidney disease among America’s veterans.

Tissue engineering of kidneys could help alleviate the shortage of kidneys for transplantation.
• A drug that activates the liver x receptor blocks expression of an inflammatory molecule involved in diabetic nephropathy, the leading cause of kidney failure.
• The drug improves kidney health and function in diabetic mice.
• Such a drug might help protect the health of diabetic patients’ kidneys.
About 20%-30% of patients with diabetes develop evidence of diabetic nephropathy.
• In the largest study of its kind, a variant within the multidrug resistance 1 (MDR-1) gene in kidney transplant donors was linked to a 69% increased risk for long-term failure of transplanted organs.
• This variant affects the expression of the protein that the MDR-1 gene encodes, which pumps drugs out of cells. (Immunosuppressant drugs are critical for preventing organ rejection but are also toxic to the kidneys.)
The high rate of non-diabetic kidney disease in African-Americans is strongly associated with variations in a particular gene. Yet, not everyone who inherits these variations develops the disease.
• Home hemodialysis could allow patients to enjoy increased freedom, quality of life, greater ability to travel, and tangible health improvements.

• Kidney disease patients and their physicians should question and discuss certain medical tests and procedures, taking into consideration patients’ preferences, needs, and health goals.
• Doing so can improve care and reduce costs. An estimated 30% of care in America goes to unnecessary tests and procedures.
• Blood tests of particular autoantibodies can accurately diagnose the autoimmune kidney disease called idiopathic membranous nephropathy.
• Patients with high levels of these autoantibodies tend to have more severe disease, while those with low levels often experience remission.
Each year, an estimated 50,000 people globally are diagnosed with idiopathic membranous nephropathy.
