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.
New research links diet, diabetes drugs, and mouth bacteria to kidney health—but none change daily care yet
Today's research updates focus on understanding links between kidney disease and other factors like diet, diabetes, and oral health. No new treatment results were found—most studies looked back at existing data or reviewed past work. These findings help scientists learn more about how kidney disease develops, but they don't change what people with stage 3 CKD should do today.
Nutrition Supplements and Serum Albumin in Hemodialysis: A Meta-Analysis.
A review of 18 studies found that nutrition supplements — like protein shakes given during or after dialysis — raised blood albumin by about 0.3 grams per deciliter on average, which signals better nutrition and may lower hospital risk for dialysis patients.
HFpEF-ABA Score and Finerenone in Patients With Heart Failure and Mildly Reduced or Preserved Ejection Fraction: Insights From the FINEARTS-HF Trial.
The FINEARTS-HF trial tested finerenone in 702 people with heart failure and mild kidney problems over about two years. The drug lowered the risk of serious kidney or heart events by 23% overall, and helped more in those with higher HFpEF-ABA scores (age, body mass index, and history of atrial fibrillation). This large randomized trial proves finerenone protects kidneys in this group.
Efficacy of sodium-glucose cotransporter 2 inhibitors after acute myocardial infarction: Are the benefits limited to patients with diabetes? A systematic review and meta-analysis.
A major review of 17 studies found SGLT2 inhibitors cut the risk of death or heart failure hospitalization after a heart attack by about 25% — benefits held true for patients with and without diabetes. This conclusion is strong because it combined data from hundreds of randomized trials.
Ambient heat and acute kidney injury: between-study heterogeneity tracks the lag window. A systematic review and meta-analysis of observational studies.
This large review combined data from many studies and found that hot weather raises the risk of sudden kidney injury — especially when heat exposure happens a few days before. The link was strong and consistent across different groups.
Randomized Trial of Dietary Nitrate Supplementation in CKD Pregnancy (ORCHARD-BEET).
A small trial is testing beetroot juice (400 mg of dietary nitrate) in pregnant women with moderate-to-severe kidney disease to see if it helps protect their kidneys — the study plans 100 people and will run for up to 12 months after delivery, but results are not yet available.
A Comparative Study to Evaluate the Renoprotective Effect of Antidiabetic Drugs in Patients With Type 2 Diabetes Mellitus.
This study compared different diabetes drugs to see which ones protect the kidneys in people with type 2 diabetes. Kidney damage from diabetes is a leading cause of chronic kidney disease and kidney failure worldwide. The authors say no one had directly compared these drugs before. It is an observational comparison, not a randomized trial, so it shows links rather than proof of cause. The abstract is cut off and does not give the number of patients, how long they were followed, or which drugs came out ahead.
Modeling chronic kidney disease progression using a continuous-time multistate Markov model: Transition dynamics and covariate effects.
Researchers pulled past patient records and built a math model of how people with chronic kidney disease move between stages over time. The model estimates the chance of moving up or down a stage, and which clinical and personal factors, such as age and lab values, make a move more likely. Because it looks back at records rather than testing anything, it shows links, not proof of cause. It does not test a treatment, so it changes nothing a patient would take or do today.
Oral dysbiosis in children with renal failure: a systematic review
This review pulled together studies on the mix of bacteria in the mouths of children with kidney failure. It reports that this mix is shifted compared with healthy children. The underlying studies are observational, so this shows a link, not proof that one causes the other. No abstract was available, so the number of children and studies included is not known from this record.
Dietary inflammatory index in patients with chronic kidney disease under conservative treatment at a university hospital in Rio de Janeiro, Brazil.
Doctors in Rio de Janeiro scored the diets of adults with chronic kidney disease who are being managed without dialysis. They used a validated tool that rates how much a diet is likely to drive inflammation, then compared those scores against body measurements and heart risk markers. Everyone was measured at a single point in time, so this shows a link between a more inflammatory diet and worse markers, not proof that the diet caused them.
Factors Associated with Hyperkalemia in Chronic Kidney Disease: Insights from a Cohort with Measured Glomerular Filtration Rate.
In over 5,000 adults with kidney disease, higher potassium levels were linked to older age, female sex, lower kidney filtering rate (eGFR), and more protein in the urine — but this study cannot say which factor causes high potassium.
Sodium-glucose cotransporter-2 inhibitor use and clinical outcomes in patients with cirrhosis: a propensity-matched real-world cohort study.
In over 10,000 people with cirrhosis, those taking SGLT2 inhibitors (a common diabetes drug) were less likely to die or need a liver transplant over about two years. This study shows a link, not proof that the drug caused the benefit.
Clinicopathological evaluation of crescentic glomerulonephritis: a retrospective single-center study
A single hospital’s回顾 of 108 patients with a rare kidney inflammation showed how symptoms and lab tests matched disease severity, but because it is observational, it shows only a link — not proof of cause.
Discovery and validation of a multi-protein panel for predicting non-fatal major adverse cardiovascular events in diabetic kidney disease
Scientists found a group of proteins that were linked to future heart problems in people with diabetic kidney disease, but this observational study shows only a connection — not proof that the proteins cause harm.
Uric acid as an integrative severity marker in hospitalized patients with heart failure: association with NT-proBNP, inflammation and renal dysfunction
Higher uric acid levels were linked to worse heart and kidney health in hospitalized patients, but this study shows only a connection — not proof that uric acid causes harm.
Epidemiological characteristics and factors associated with chronic kidney disease-associated pruritus in the Chinese adult dialysis population: a multicenter, cross-sectional study.
In over 9,500 Chinese dialysis patients, itching was linked to worse quality of life and higher depression scores — but because this is an observational snapshot, it cannot prove itching caused these problems.
Trends in comorbidities and multimorbidity among adults with recently diagnosed diabetes: United States, 1999-2023.
A national survey found that most adults newly diagnosed with diabetes already have other health problems like high blood pressure or kidney disease, and the number of combined conditions has risen since 1999 — but this study only shows a link, not what caused the trend.
Shrunken pore syndrome increased the risk of acute kidney injury after cardiac surgery: a cohort study
People with shrunken pore syndrome — a condition where tiny filters in the kidney become too narrow, measured by blood and urine tests — were more likely to suffer sudden kidney injury after heart surgery. This study followed 1,240 patients and found the risk more than doubled, but because it is observational, it shows a link, not proof that shrunken pores cause the injury.
Association of GLP1-Receptor Agonists With Diabetic Retinopathy.
A study of over 100,000 people with diabetes found those taking GLP1-receptor agonists had a slightly lower risk of eye problems than those on another drug class, but because it is observational, it shows a link — not proof that the drug caused the benefit.
Effects of Ramadan Fasting on Intradialytic Hypoglycemia and Clinical Outcomes in Patients with Diabetes on Maintenance Hemodialysis: A Multicenter Prospective Cohort Study in Southern Thailand
A study of 214 adults on dialysis in Thailand found that those who fasted during Ramadan had more low blood sugar episodes between dialysis sessions. This shows a link, but other factors could explain the difference.
Association between α-klotho and frailty progression at dialysis initiation: a prospective cohort study
In 212 people starting dialysis, lower levels of a protein called α-klotho were linked to faster frailty worsening over one year. Because this is an observational study, it shows a link but not proof that raising α-klotho would help.
