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.
Nothing new changes your care today, but a scan score is a worth-watching signal
-
Three new trials opened but have no results yet, covering virtual care for high risk patients, a diabetes drug for people close to dialysis, and breathing muscle training during dialysis.
Today brought no new treatment results for kidney disease. The strongest item was a pooled review linking hardened arteries in the belly to worse outcomes, which points to a scan score doctors could use to flag higher risk. Almost everything else looked at links rather than causes, including studies of hospital costs, physical strength, and mouth health. Several papers were preprints, meaning other scientists have not reviewed them yet, so treat their findings as early.
Abdominal aortic calcification index and prognosis in patients with chronic kidney disease: a meta-analysis
This review pooled many earlier studies that scored calcium buildup in the main artery of the belly on scans in people with kidney disease. It asked whether a higher score goes with worse outcomes later, such as heart problems and death. The pooled studies watched people over time rather than testing a treatment, so the pattern is a strong link, not proof that the calcium itself does the harm. A scan score like this could help flag who needs closer watching.
Effects of Brussels Chicory and Concurrent Exercise Training on HDL Function and Subclass Profiles in Overweight College Students: A Pilot Randomized Controlled Trial.
This was a small pilot study in overweight college students who were split at random into three groups. One group took a supplement made from Brussels chicory, a leafy vegetable rich in plant compounds called phenolic acids. The other two added either supervised exercise or exercise with mindfulness training on top of the supplement. The report we have does not give the number of people or how long it ran, and it measured lab markers of good cholesterol function rather than any health outcome.
Latent histopathological activation of the renin–angiotensin–aldosterone system in children with low birth weight
Researchers examined kidney tissue from children who were born small, at a low birth weight. They found quiet signs that the hormone system controlling blood pressure and salt, called the renin-angiotensin-aldosterone system, was switched on. That system is the target of common blood pressure drugs. This shows a link, not proof that low birth weight causes the change, and it is a preprint that other scientists have not checked yet.
Clinical characteristics and prognosis of IgA nephropathy and comorbid diabetic kidney disease
This study looked at people who have two kidney diseases at once: IgA nephropathy and diabetic kidney disease. IgA nephropathy is when the immune system damages the kidney's tiny filters. The researchers compared symptoms, lab results and later outcomes against people who had only one of the two conditions. It looks back at existing records, so it can show a link between having both diseases and how people did, not proof that one caused the other.
Plasma neurofilament light chain in type 2 diabetes: Associations with diabetic peripheral neuropathy, age, and renal function in a pilot cross-sectional study
This small study measured a blood marker of nerve damage, called neurofilament light chain, in people with type 2 diabetes. It checked whether the marker tracks with nerve damage in the hands and feet, with older age, and with the kidney filtering rate (eGFR). Everything was measured at one point in time, so it can show a link, not proof of cause. The authors call it a pilot, meaning a first look that needs a bigger study to confirm.
Vasculitis Syndromes with Renal Involvement: A Review from a Case Series.
This review explains vasculitis, which is inflammation of blood vessels, when it attacks the kidneys, using real patient cases. Two forms, microscopic polyangiitis and granulomatosis with polyangiitis, often move fast and can reach kidney failure within months. Other forms start with fever and high inflammation blood tests while kidney function still looks normal, and only a kidney biopsy finds them. Because it draws on a series of cases, it teaches patterns to watch for, not proof of which treatment works best.
A comparative real-world analysis of finerenone and steroidal mineralocorticoid receptor antagonists in patients with chronic kidney disease
This study compares finerenone, a newer kidney and heart drug, with older drugs in the same family such as spironolactone. It uses real-world records of people with chronic kidney disease who were already taking these drugs, so it can show a link, not proof of cause. The full abstract was not available in this sweep, so how much better either drug did is not known yet.
Comprehensive Haematological Alterations in Chronic Kidney Disease: Pathophysiological Mechanisms and Clinical Implications in Patients Attending Private Hospitals in Baghdad
Doctors in Baghdad looked at blood test changes in people with chronic kidney disease at private hospitals. Kidney disease often lowers red blood cells, which causes tiredness and shortness of breath. This is a look-back study, so it shows a link between kidney disease and these blood changes, not proof of cause. It was posted to a public repository and has not passed peer review.
SGLT2 Inhibitors in Nephrolithiasis: Emerging Evidence and What Urologists Need to Know
This review pulls together what is known about SGLT2 inhibitors and kidney stones. SGLT2 inhibitors are diabetes drugs that also slow kidney decline. The evidence so far comes from watching patients rather than testing the drugs against stones directly, so it shows a link, not proof that these drugs prevent stones.
Cardio-Renal Interaction Between NT-proBNP and Renal Function Across Chronic Kidney Disease Stages in Patients with Heart Failure
This study looked at NT-proBNP, a blood marker of heart strain, in people with heart failure at different stages of kidney disease. Weak kidneys raise this marker on their own, which makes the heart test harder to read. It is an observational study, so it shows a link between kidney function and the marker, not proof of cause.
Random Urinary Calcium/Creatinine Ratio as a Predictor of Dehydration in Hypercalcemic and Normocalcemic Patients
This study tested whether one urine sample, comparing calcium against creatinine, can flag dehydration. Creatinine is a waste product used to judge how concentrated the urine is. It is an observational study, so it shows a link, not proof of cause. Spotting dehydration early matters because it can injure the kidneys.
Birth characteristics and growth outcome in children with nephropathic cystinosis compared with other chronic kidney disease entities prior to kidney replacement therapy
Researchers compared birth size and later growth in children with nephropathic cystinosis, a rare inherited disease that damages the kidneys, against children with other kinds of chronic kidney disease. All the children were still before dialysis or a transplant. The comparison points to differences in how these children grow, which matters because poor growth is a warning sign in childhood kidney disease. This is an observational study, so it shows a link and not proof of cause.
Reciprocal mediation of immuno-inflammation and insulin resistance in the risk of chronic kidney disease among patients with coronary artery disease: insights from neutrophil-to-lymphocyte ratio and triglyceride-glucose index
In people with clogged heart arteries, researchers checked two cheap blood markers: one for inflammation, based on the ratio of two white blood cell types, and one for insulin resistance, based on blood fat and blood sugar. Higher levels on both tracked with a higher chance of having chronic kidney disease, and each one seemed to carry part of the other's effect. That fits the idea that inflammation and blood sugar problems feed each other and wear on the kidneys. This is an observational study, so it shows a link, not proof that either marker causes kidney damage.
Alterations in physical performance and body composition in non-dialysis chronic kidney disease detected by a comprehensive multidimensional analysis
Researchers measured strength, movement, and body makeup in people with kidney disease who are not on dialysis. They looked at several measures together instead of one at a time, and found differences across them. This shows a link between kidney disease and weaker physical function, not proof of cause. It is a preprint, so other scientists have not reviewed it yet.
Oral beta-D-glucan challenge to assess gut permeability in subjects receiving haemodialysis
People on dialysis drank a sugar from yeast cell walls, beta-D-glucan, to test whether their gut lining leaks. If the sugar shows up in the blood, the gut wall is letting things through that it normally blocks. A leaky gut is one suspected source of the body-wide inflammation common in kidney failure. This was a small test of a measuring method, not a treatment trial, and the record here gives no participant count or results.
Development and preliminary psychometric evaluation of an oral health questionnaire for chronic kidney disease (CKD-OHQ)
Researchers built a questionnaire that asks people with kidney disease about their teeth, gums, and mouth problems. They gave it to a first group of patients to see if the questions were clear and if the scores held together. This is an early test of a measuring tool, not evidence that mouth care protects kidneys. Mouth problems are common in kidney disease, so a standard way to ask about them is useful.
The Circadian System and Chronic Kidney Disease Risk: Epidemiological Evidence.
About 10% of people worldwide have chronic kidney disease. This review gathers past studies on whether a disturbed body clock raises that risk, looking at night shift work, artificial light at night, the sleep hormone melatonin, and general sleep health. It summarizes studies that watched people rather than testing anything, so it shows links, not proof of cause. No one here tested whether fixing sleep protects kidneys.
Clinical, Social, and Healthcare Factors Associated with Nutritional Status in Amyotrophic Lateral Sclerosis: A Multidimensional Approach.
Researchers checked the nutrition of 97 adults with ALS, a disease that slowly weakens the muscles, at one point in time. They looked for which clinical, social, and care-system factors went along with being underfed or at risk of it. Because everyone was measured only once, this shows links, not proof that any factor causes poor nutrition. Nothing in it concerns the kidneys.
Epidemiology And Multimorbidity Burden Of Arthritis Among Elderly Patients: A Hospital-Based Cross-Sectional Study In South India
This hospital record posted to an open repository counts how common arthritis is among older patients in South India and what other illnesses they carry alongside it. Patients were looked at once, so it can show which conditions travel together, not which one causes another. No abstract or numbers came with the record, so the size and findings cannot be checked. It is a repository deposit, not a peer-reviewed journal article, and it is not about kidney disease.
Long COVID-19 in Spain: A Phenomenological Exploration of Health, Support, and Systemic Challenges.
This study interviewed 36 people in Spain who live with long COVID, across 17 provinces over 10 months. It is a listening study: it reports what people said about their health, the support they got, and where the health system failed them. It describes experience, so it shows patterns in what people report, not cause and effect. It does not deal with kidney disease.
