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.
No new treatment results today — mostly early studies and reviews
-
A review of blood tests used when heart and kidney failure occur together was published, but it does not include new trial data.
Today’s research update shows no new treatment results for kidney disease. Most items are early-stage studies, reviews without fresh data, or observational links that cannot prove cause-and-effect. One pilot study explored contact-free heart rate monitoring during dialysis, and another looked at GLP-1 drugs and kidney cancer risk after surgery — both need more research. Several educational resources and guidelines were also released, emphasizing the importance of understanding links between heart health, blood pressure, and kidney function.
The effectiveness of nature-based interventions on mental health: A systematic review.
A large review of many studies found that spending time in nature — like walking in a park or gardening — lowered anxiety and depression symptoms, even in people with long-term health problems — but most studies were small and did not focus on kidney disease specifically.
Pharmacokinetics, Elimination and Dialyzability of HRS-9231 in Patients with Varying Degrees of Renal Impairment.
A new dye used in imaging tests was studied in 40 people with kidney disease, including those on dialysis — the study found how quickly the body removes it, which helps doctors choose safer doses.
Lifestyle Intervention and Its Effects on Inflammatory Cytokines and Oxidative Stress Markers in Diabetic Chronic Kidney Disease Patients: A Randomized Controlled Trial
A randomized trial tested a lifestyle program in people who have both diabetes and kidney disease. It measured inflammation markers and oxidative stress markers, which are blood signs of irritation and cell damage. The record we received does not say how many people took part or how long it ran, so the strength of the result cannot be judged. It also measured lab markers, not kidney function over time, so it does not show slower kidney decline.
Efficacy and safety of finerenone in adults with IgA nephropathy: a 12-month real-world study.
Among 142 adults with IgA nephropathy, the drug finerenone lowered protein in the urine by about 35% and slowed kidney filtering rate decline over 12 months — but this small real-world study lacked a comparison group, so the exact benefit is uncertain.
Broccoli Sprout Extract for Glycemic Management in Patients with Chronic Kidney Disease and Type 2 Diabetes: A Randomized Double-Blind Placebo-Controlled Trial.
In a small trial of 120 people with type 2 diabetes and stage 3b–4 kidney disease, those who took broccoli sprout extract for 12 weeks had blood sugar levels drop about 0.8% on average, compared to almost no change in the placebo group.
Clinical and genetic spectrum of distal renal tubular acidosis in children: findings from Indian tubular disorders registry
Doctors in India pulled together registry records of children with distal renal tubular acidosis, a condition where the kidneys cannot clear acid from the blood properly. The report describes what these children looked like clinically and which gene changes were behind it. It looks back at records already collected, so it describes patterns and does not prove cause. It helps with diagnosis in children, and it is not a new treatment.
GLP-1 receptor agonists are associated with lower kidney cancer risk after metabolic bariatric surgery.
People who took GLP-1 drugs after weight-loss surgery had lower kidney cancer risk than those on other diabetes medicines, but this study only shows a link — it cannot prove the drug caused the lower risk. The data came from past records, not a planned experiment.
Feasibility of heart rate monitoring in hemodialysis patients using visible imaging: a pilot study
Researchers tested whether an ordinary video camera can read heart rate in people during dialysis, with nothing touching the skin. This was a pilot, a small first test of whether the idea works at all, and the report does not give the number of patients. Contact-free monitoring could in theory catch heart rate trouble during a session. This study only shows the method is workable, not that it helps anyone.
Factors Associated with Poor Knowledge of Chronic Kidney Disease in the General Population of Abomey-Calavi (Benin): A Cross-Sectional Study
A survey in Abomey-Calavi, Benin asked members of the public what they knew about chronic kidney disease. Knowledge was poor overall, and the study looked at which groups knew the least. The record here does not give how many people were surveyed. A survey like this shows links between background and awareness, not proof of cause, and it measures what people know rather than how they are treated.
Adaptive immune cells and kidney function in older adults: sex-specific associations in the health and retirement study (HRS)
Researchers looked at immune cells in the blood and kidney filtering rate (eGFR) in older adults taking part in a large US study on aging. Certain immune cell patterns tracked with worse kidney function, and the pattern was not the same in men and women. This is an observational study, so it shows a link, not proof of cause. The record we received did not include the number of people.
Plasma Levels of Growth Differentiation Factor 15 and Adverse Kidney Outcomes
Researchers measured a blood protein called GDF-15, a signal the body makes when cells are under stress, and then tracked how people's kidneys did over time. Higher levels went along with worse kidney outcomes. This is an observational study, so it shows a link, not proof that the protein causes the damage. The record we received did not include the number of people or the follow-up time.
Exploring the Relationship of Serum Albumin With Different Stages of Chronic Kidney Disease: A Cross Sectional Study in a Tertiary Care Hospital
This hospital study looked at whether blood levels of albumin, the main protein in blood, drop as chronic kidney disease gets worse. It measured everyone at a single point in time at one tertiary care hospital. That design shows a link between lower albumin and later kidney stages, not proof that one causes the other. Low albumin often reflects poor nutrition and inflammation, so it is a marker to watch, not a target to treat on its own.
Combined Assessment of Estimated Glomerular Filtration Rate and Albuminuria Among Apparently Healthy Young Adults: A Cross-Sectional Study
This study measured two kidney tests at once in healthy young adults: the kidney filtering rate (eGFR) and protein leaking into the urine (albuminuria). It is a snapshot of one group at one point in time, so it can show how often early kidney trouble turns up in young people, but it cannot show what causes it or what happens next. The paper does not report how many people were screened or what they found, so treat the size of the signal as unknown.
Association of low calf circumference and underweight with sarcopenia in older adults with chronic kidney disease: a cross-sectional study
In older adults with chronic kidney disease, thinner calves and low body weight went along with sarcopenia, which is serious loss of muscle and strength. This was a snapshot study, measuring everyone at one point in time, so it shows a link and not proof of cause. Calf size is easy to measure with a tape, so it may be a simple way to spot people who need a muscle check. The record we received did not include the number of people.
Effectiveness of Acupuncture Combined with Nursing in Children with Nondialysis Chronic Kidney Disease: A Retrospective Study
This study looked back at records of children with chronic kidney disease who were not on dialysis and compared those who got acupuncture plus nursing care with those who got nursing care alone. Because it looks backward at care that already happened, the groups were not randomly assigned. Children whose families chose acupuncture may differ in many ways from those who did not, and any of those differences could explain the result. This shows a link at best, and for a mind-body treatment in children that is a long way from evidence it works.
Merging artificial intelligence and retinal vascular geometric parameters: A novel tool for diagnosis and prognosis prediction of diabetic nephropathy.
Scientists built a tool using eye scans and health data to predict diabetic kidney disease, but this study only shows a link — it did not prove the tool can reliably diagnose or prevent kidney decline in real-world use.
Effect of Contrast-Enhanced CT Brain on Renal Function in Potential Intraarterial Therapy Patients in the Emergency Department.
In 112 emergency room stroke patients who got a CT scan with contrast dye, kidney filtering rate dropped slightly on average — but this observational study cannot prove the dye caused the drop, only that it often happened together.
Association of routine laboratory parameters with chronic kidney disease-mineral and bone disorder in patients on maintenance hemodialysis: A retrospective study.
In 156 adults on dialysis, routine blood tests like calcium and phosphate levels were linked to bone and mineral problems — but this retrospective study shows only an association, not that those lab values caused the issues.
Association of Microalbuminuria, Protein-Creatinine Ratio, and Derived Renal Risk Indices in Patients With Type 2 Diabetes Mellitus in a South Indian Population: A Cross-Sectional Study.
In 204 South Indian adults with type 2 diabetes, higher protein in the urine and certain lab ratios were linked to worse kidney health — but this study cannot prove those things cause kidney damage, only that they tend to occur together.
Diagnostic Performance of Reticulocyte Hemoglobin Content (CHr) for Iron Deficiency in Chronic Kidney Disease: A Reanalysis of a Published South African Dataset.
A reanalysis of 399 South African patients found that measuring iron in new red blood cells (called CHr) worked better than the usual ferritin test to spot true iron deficiency in people with chronic kidney disease, but because it is an observational study, it shows only a connection — not proof that CHr causes better outcomes.
