A large UM study found that mycophenolate mofetil (MMF) reduces the risk of losing a transplanted kidney due to chronic failure better than azathioprine (AZA). MMF protects against kidney loss even when acute rejection prevention effects are eliminated, with nearly 86% of MMF-treated kidneys surviving four years.
A new, less invasive approach to removing a kidney from living donors has more than doubled the chance of patients receiving a transplant from a friend or loved one. The technique, combined with an educational program, has increased living donor transplants by half, with 40% of recent transplants coming from living donors.
Researchers at Yale have discovered new insights into the development of polycystic kidney disease (PKD), a life-threatening genetic disorder affecting millions. The study reveals crucial information about the PKD2 gene's role in normal development and its impact when mutated.
A Harvard study finds that racial differences in kidney transplant access cannot be explained by patient preferences, with black patients being less likely to be referred for evaluation or receive a transplant. The disparity remains even after controlling for coexisting illnesses and socioeconomic factors.
A new study of 27,050 kidney transplants found that patients with locally matched kidneys require less long-term care and incur lower costs. The average cost to Medicare was $60,436 for identical HLA markers, increasing by 34% as mismatches rose from one to six.
Researchers at Wake Forest University School of Medicine have cloned the gene responsible for primary hyperoxaluria type II, a rare inherited form of kidney stone disease. The discovery may lead to better understanding and treatment of the disease, which can cause severe kidney failure and early death if left untreated.
A recent study suggests that the immune system protein CD2AP may play a critical role in kidney function. Researchers found that mice lacking CD2AP developed defective glomeruli and died of renal failure, highlighting the protein's importance in maintaining kidney health. The discovery also sheds light on other diseases, such as congen...
Researchers identify nephrin's role in the kidney's filtration barrier, finding a 'zipper-like' structure that allows blood to pass but not plasma proteins. Increasing nephrin production or restoring its function is thought to improve kidney function and restore proteinuria.
A study of over 50,000 transplant recipients found that kidney transplants from living donors are more cost-effective than dialysis treatments. The total cost of care within five years is roughly $47,000 less for living donor transplants compared to dialysis.
A recent study by University of Maryland researchers found that kidney transplants are more cost-effective than dialysis, even for the sickest patients. The break-even point for kidney transplants was 2.7 years compared to dialysis, saving $27,000 per year for each patient.
A new procedure called High PRA Rescue cleanses blood of harmful rejection antibodies, enabling six patients to receive successful kidney transplants from living donors. The innovative technique, combined with three new anti-rejection medications, has shown promising results in a two-week period.
A new study of 27,050 kidney transplants reveals that the need for care within three years increases significantly as the number of mismatched surface markers increases. The cost of care rises by up to 34% with more mismatches, making well-matched organs a more cost-effective option.
Researchers found that improving kidney function in majority of patients can be achieved by reducing cyclosporine dosage and adding mycophenolate mofetil, potentially slowing kidney deterioration. The study showed an improvement in kidney function in 37 patients over two years.
Researchers discovered Wnt-4's role in regulating kidney development through inducing tubulogenesis in isolated mesenchyme. Additionally, Wnt-4 suppresses male cell fates in female embryos, affecting sex organ differentiation. It also mediates tissue interactions involved in neuronal growth and axonal guidance.
Researchers found that maternal HLA typing can provide clues about which sibling is the optimal organ donor. This discovery could improve kidney transplant selection by identifying suitable donors beyond HLA-identical siblings.
Researchers found that maternal tissue types can improve survival rates of slightly mismatched kidney transplants. The study suggests adding maternal HLA typing to the routine family workup could expand the pool of optimal donors.
A study by University of Florida researchers found that cystic fibrosis patients who lack the beneficial intestinal bacterium Oxalobacter formigenes are at a greatly increased risk of developing kidney stones. The absence of this organism can lead to high levels of oxalate, which can crystallize and form painful stones in the kidneys.
Researchers at UT Southwestern Medical Center have developed a new test to accurately measure kidney function, enabling patients to spend less time in the clinic. The new procedure involves injecting a small amount of radioactive isotope solution and estimating how quickly it disappears from the blood and appears in the urine.
Researchers at the University of Chicago have discovered a new protein, calgranulin, that can prevent the formation of kidney stones in minute amounts. Calgranulin is present in the kidney and human urine and can stop the growth of calcium oxalate crystals, the major component of kidney stones.
Researchers at Washington University School of Medicine have successfully grown new kidneys in rats by placing developing rat kidneys inside adult rat abdominal cavities. The resulting organs function and thrive, suggesting a possible alternative to traditional kidney transplantation.
A synthetic detergent, nonylphenolethoxylate (NPE), commonly used in household cleansers, has been discovered to block a drug pump in cancer cells, reducing the need for chemotherapy drugs. The researchers found NPE present in human urine and suggest it could be a useful adjunct to standard treatments.
Researchers found that an immunosuppressive drug commonly used to prevent kidney transplant rejection also improved patients with severe symptoms of kidney disease. The treatment reduced protein leaks and alleviated fluid retention, correcting high cholesterol levels without the negative side effects of steroids.
Researchers have discovered a novel physiological role for UG in mice, suggesting its essentiality in preventing kidney fibrosis and neonatal BPD. UG deficiency leads to inflammation and fibrosis of lung tissue, resulting in respiratory inhibition.
Researchers discovered a genetic mutation in people with Alport syndrome prevents normal transformation process in collagen proteins, leading to gradual loss of membrane integrity. The mutation affects production of alpha-5 collagen, resulting in breakdown of critical glomerular basement membrane.
A new laparoscopic technique for kidney removal has been shown to reduce pain, hospital stays, and recovery time compared to traditional methods. The study found that kidneys removed with this technique function as well as those taken out with a large incision.
A study of kidney patients found that those taken off steroids had significantly better one- and three-year survival rates compared to those still on the medication. One-year patient survival was 99% in the group no longer taking steroids, while one- and three-year graft survival rates were also higher.
A new laparoscopic technique has made kidney donation easier, with reduced recovery time and complications. The procedure involves a small incision and minimizes blood loss, allowing donors to recover in one-third less time compared to traditional surgery.
A multi-center trial involving 73 patients found that tacrolimus rescue therapy effectively reverses refractory kidney rejection, maintains long-term kidney function, and reduces repeat rejection. The study's results suggest a significant advance in reducing organ loss from persistent kidney rejection.
