Decline is not inevitable.

A daily, evidence-graded view of everything moving in kidney research : the drugs that slow decline, the science of regeneration, and the mind-body work.

A new check helps confirm if you are taking your kidney-protecting medicine.

Key takeaways

The main news today is a practical tool for monitoring SGLT2 medication use. This helps ensure patients get the full benefit of their treatment. Other items are preliminary and do not change current care.

Hepatitis E virus immunoglobulin G seropositivity and kidney dysfunction among United States adults

This preprint checked if past exposure to Hepatitis E virus is linked to kidney problems in US adults. It used data from national health surveys. It is an observational study, so it shows a link, not proof of cause. The study is not yet peer-reviewed, so the findings are preliminary.

Association between blood urea nitrogen-to-albumin ratio and kidney stones: A cross-sectional study based on NHANES

This preprint looked at a blood test ratio called BAR and its link to kidney stones. It used data from the NHANES survey. It is an observational study, so it shows a link, not proof of cause. The study is not yet peer-reviewed, so the findings are preliminary.

CONTRAST-INDUCED NEPHROPATHY IN PATIENTS WITH STABLE CORONARY ARTERY DISEASE AND PROGNOSIS OF CHRONIC KIDNEY DISEASE

This study looked at 462 people with heart disease who had a dye test. It checked if the dye caused kidney damage. It also tracked what happened to them over one year. This is an observational study, so it shows a link but not proof of cause. It helps us understand the risks of these tests.

Efficacy and safety of telitacicept combined with standard of care in patients with proliferative lupus nephritis: a real-world retrospective study.

This study looked at 112 people with lupus kidney disease. It compared a drug called telitacicept with standard care. It is a retrospective study, so it shows a link, not proof of cause. The drug may help control the disease.

Association between central thyroid hormone dysregulation and chronic kidney disease in type 2 diabetes: a cross-sectional study.

This study looked at 2,759 people with type 2 diabetes. It found a link between thyroid hormone issues and kidney disease. This shows a connection, but it does not prove that one causes the other.

African-specific variants at the GATM locus and genetic bias in creatinine-based GFR estimation

This study explains why kidney function tests can be less accurate for people of African ancestry. A specific gene change causes the body to make more creatinine, a waste product. This raises the creatinine level in the blood without actually changing how well the kidneys filter. The result is that standard tests may underestimate kidney function in these patients. This finding helps doctors interpret test results more fairly.

Perinatal Risk and Outcomes Among Individuals Insured by Medicare

This study compared pregnant women on Medicare with those on other insurance. It looked at health risks and baby outcomes. This is an observational study, so it shows a link but not proof of cause. It helps us understand the challenges for pregnant people with chronic conditions.

Increased mechanical load remodels the glomerular matrix and accelerates Alport kidney disease: processed data and analysis code

This study used mice to see how extra stress on the kidney changes its structure. It found that this stress can speed up a specific type of kidney disease in the animals. The data is from lab tests, not from people yet.

Cadherin-11 and the mechanobiology of the fibrogenic niche

Researchers found that blocking a protein called cadherin-11 can limit scarring in the kidneys. This was tested in animal models of kidney injury, not in people yet. The protein helps cells generate force, which drives the scarring process. Stopping this process preserved kidney function in the animals. This suggests a new target for future drugs to prevent kidney damage.
