A new study has discovered how the enzyme heme oxygenase-1 (HO-1) regulates immune cells in response to kidney injury. The research found that HO-1 directs a specific subset of myeloid cells to and from the kidney, which helps protect against poor recovery after acute kidney injury.
Patients with chronic kidney disease who consume high acid diets are 3-times more likely to develop kidney failure than those on low acid diets. A diet rich in fruits and vegetables can help protect kidneys.
A simple test using furosemide and urine output can predict which patients with acute kidney injury (AKI) are at risk of developing serious kidney problems. The Furosemide Stress Test (FST) improved predictions of outcomes in patients with early AKI, paving the way for robust clinical diagnostic tools.
A recent study found that women with kidney transplants in childhood and adulthood have comparable live birth rates, premature birth rates, and small-for-gestational-age babies. The findings suggest that early onset of kidney failure and longer periods of immunosuppression do not negatively impact pregnancy outcomes.
A new review highlights techniques to provide optimal dosing recommendations for patients with kidney disease. Mathematical modeling tools can help analyze clinical program level data to inform dosing decisions.

Targeting this nerve reduced salt-induced kidney scarring, providing new strategies for protecting patients' kidney health.
A study found that people with recurrent kidney stones have more calcification in their arteries, increasing their risk for heart disease. Additionally, kidney stone formers tend to have less dense bones, elevating their risk for osteoporosis.
Researchers discovered that babies born with smaller kidneys are more likely to develop chronic kidney disease and high blood pressure as adults. The study found enhanced nerve activity and an inability to respond to nitric oxide promote kidney injury.
High-dose atorvastatin therapy has been linked to reduced blood levels of creatinine and lower incidence of acute kidney injury in heart surgery patients. This finding comes from an analysis of 14 randomized controlled clinical trials involving 1689 patients.
A UK hospital performed the world's first successful organ donation from a newborn, involving kidney and liver cell transplants. The donor was just over 3 kg at birth and had poor brain oxygenation, leading to her death; however, her parents agreed to donate her organs for other patients in need.
A Pitt study links biomarkers to long-term kidney damage and death in critically ill, highlighting the importance of early intervention. Researchers found that tissue inhibitor metalloproteinase-2 (TIMP-2) and IGF-binding protein-7 (IGFBP7) can identify patients at increased risk for adverse outcomes.
A study by Penn Medicine found that many patients with type 2 diabetes are being discouraged from taking metformin due to an overly conservative FDA label. The authors recommend amending the label to reflect more modern guidelines, which could extend the drug's use to nearly 1 million additional patients.
Researchers at University of Cincinnati discover a new drug therapy that effectively lowers antibodies in kidney patients, paving the way for more successful kidney transplants. The study suggests this approach could benefit up to 10-20% of heart and pancreas transplant candidates who are currently ineligible due to high antibody levels.
A systematic review of the literature suggests that metformin is safe for patients with mild to moderate kidney disease, contrary to FDA guidelines. The risk of lactic acidosis is extremely low and comparable to those who do not take metformin.

Additionally, new treatments for End-Stage Renal Disease (ESRD) have shown promising results, such as ferric citrate's abi...
A study found that perceived racial discrimination may contribute to disparities in kidney disease by increasing stress-related pathways. Among African Americans and whites, those who experienced 'a lot' of discrimination had higher systolic blood pressure but a lower prevalence of diabetes.
A recent study published in JAMA found that taking aspirin or clonidine before and after surgery did not lower the risk of acute kidney injury. The study involved over 6,900 patients and showed that major bleeding with aspirin increased AKI risk, while low blood pressure with clonidine had a similar effect.
Researchers found that peritoneal dialysis and high-frequency home hemodialysis can significantly reduce mortality risks. Patients receiving these treatments had 10-26% lower mortality rates than those with standard in-center hemodialysis.

A new multi-center study has confirmed that specific gene variants in African American kidney donors are associated with a higher risk of organ failure after transplantation. The findings suggest that rapidly genotyping deceased donors for these variants could help inform organ allocation and consent processes.
A new study published in PLOS Medicine has developed a 17-gene set to analyze peripheral blood samples and determine which patients are at risk of acute rejection after kidney transplantation. The test, called kSORT, was found to be highly accurate and clinically applicable, with an area under the curve of 0.93.

The study analyzed data from 537 patients and found that those who were classified as frail had a mortality rate twice that of non-frail patients.
A Mediterranean-style diet is associated with a 17% decreased likelihood of developing chronic kidney disease, while dietary patterns resembling the diet reduce risk by 50%. More than 20 million US adults have chronic kidney disease.
A recent study found that home blood pressure monitors can be inaccurate, with systolic readings off by as much as 5mm Hg and diastolic readings off by as much as 10mm Hg in up to 30% of patients. The American Society of Nephrology recommends that all patients with home monitors get them validated with their healthcare providers.
A study of 51,785 individuals with kidney stones found a significant link between the condition and an increased risk of bone fractures. The excess risk was greatest in males during adolescence and women during middle age.

A new blood test has been identified as a potential predictor for focal segmental glomerulosclerosis (FSGS), a devastating form of kidney disease. The test, called FAST, uses high-density protein tests to detect antibodies against specific antigens that are significantly increased in patients at risk for FSGS.
