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.
One combination treatment for a filter disease moved forward, but most of today was early work
-
Most of the rest of today was early laboratory work in mice and cells, plus one single patient case, so none of it changes what anyone should do now.
Today leaned early. The strongest item was a B grade report on combining sparsentan with an SGLT2 inhibitor in IgA nephropathy, a disease where the immune system damages the kidney filters, and both drugs reduce protein in the urine. Everything else was C grade or lower: studies that can show links but not causes, laboratory work in mice and cells, and one football player's case. Several items circled the same theme, that heart and blood vessel health is tightly tied to kidney health, which is worth raising with your care team even though no single study today settles it.
Cardiorenal Protection in Type 2 Diabetes: A Systematic Review Comparing Glucagon-Like Peptide-1 Receptor Agonists and Sodium-Glucose Cotransporter-2 Inhibitors.
This systematic review looked at many large trials and found both GLP-1 receptor agonists and SGLT2 inhibitors slow kidney decline and lower heart risks in type 2 diabetes, even beyond lowering blood sugar. The benefit was clear across hundreds of patients and hard outcomes like kidney failure or death.
Supporting data for: Metabolic Bariatric Surgery as a Bridge to Kidney Transplantation in Patients with Obesity and Advanced Kidney Disease: A Systematic Review and Meta-Analysis
This is the data file behind a review that pooled results from many earlier studies. It looked at weight loss surgery for people with obesity and advanced kidney disease who want a kidney transplant. That question matters because many transplant centers will not list someone above a certain weight. This record holds the raw numbers only, so how much the surgery helped is not stated here.
Sparsentan - SGLT2 inhibitor combination therapy in trials of IgA nephropathy.
Sparsentan is a drug that blocks two separate signals that raise pressure inside the kidney filters. This report tests it alongside SGLT2 inhibitors, diabetes drugs that also protect kidneys, in people with IgA nephropathy, a disease where the immune system damages the filters. Both drugs cut protein in the urine, the main sign of damage in this disease, and the report asks whether the pair is safe and works together. It draws on SPARTACUS, a phase 2 open-label study, plus an extension of the larger PROTECT trial; the number of people and the follow-up time are not stated in the abstract available here.
Determinants of biochemical factors and microalbuminuria among type 2 diabetes mellitus patients.
This study compared 90 healthy people against people who had type 2 diabetes, some for less than five years and some for more than five. It measured fasting blood sugar, HbA1c (a three month blood sugar average), and cholesterol, then checked how those lined up with small amounts of protein in the urine, an early sign of kidney damage. Because nobody was treated or assigned to a group, this design can only show links between numbers. It cannot show that one thing causes the other.
Protein mediators of chronic kidney disease in Type 2 diabetes: A mendelian randomization study.
Kidney disease shows up in 20 to 50 percent of people with type 2 diabetes, and it is the top cause of kidney failure worldwide. Scientists used gene data from very large groups to find blood proteins that sit between diabetes and kidney damage, and flagged 71 of them. The method leans on genes people are born with, which is stronger than a plain survey, but it still shows a link rather than proof of cause. No one was given a treatment in this study.
Sports Nephrology: Managing Hypertension, Acute Kidney Injury, and Cardiovascular Risk in a Collegiate Football Player.
A 19 year old college football player had high blood pressure that would not come down with treatment, plus a recent kidney injury from losing too much body fluid. Testing found he carried one risk copy of the APOL1 gene, which is tied to higher kidney disease risk. His doctors cut back on water pills and tailored his care around training and diet. This is a single patient's story, so it cannot show what will work for anyone else.
Spontaneous All-Sequence Baroreflex Sensitivity Across Predialysis Chronic Kidney Disease Categories: A Cross-Sectional Study.
Your body has a reflex that adjusts your heart rate when your blood pressure changes. This study measured how well that reflex works in people with kidney disease who are not yet on dialysis, comparing the different stages of the disease. Everyone was tested at one point in time, so the results can show a link between worse kidney function and a weaker reflex, not proof that one causes the other. A weak reflex matters because heart problems are the biggest danger for people with kidney disease.
Development of a multivariable clinical prediction model for acute kidney injury after valve replacement surgery: incremental value of the triglyceride-glucose body mass index.
This study found that a simple score combining triglycerides, blood sugar, and body mass index (TyG-BMI) helped predict who would get sudden kidney injury after heart valve surgery, but because it is observational, it shows only an association—not proof the score causes or prevents injury.
Circulating Soluble Thrombomodulin Is Elevated in Early-Stage CKD and Is Associated with Renal Dysfunction: A Transcriptomic and Retrospective Cohort Study
A study of people with early kidney disease found higher levels of a protein in the blood linked to worse kidney filtering rate (eGFR), but this only shows a connection — it does not prove the protein causes harm. The study included 1,240 adults and used existing medical records.
Clinical Factors Associated with Short-Term Decline in Estimated Glomerular Filtration Rate in People Living with HIV Receiving Antiretroviral Therapy: A Prospective Cohort Study
This study followed people with HIV on standard treatment and found that higher blood pressure, older age, and lower starting kidney filtering rate (eGFR) were linked to a faster drop in kidney function over about one year. Because it only observed people and did not change their care, it shows a link but does not prove cause and effect.
Prevalence and factors associated with malnutrition among patients with pre-dialysis chronic kidney disease stages 3-5.
This cross-sectional study found that nearly half of people with pre-dialysis kidney disease stages 3 to 5 had malnutrition, and lower income, worse kidney filtering rate (eGFR), and more inflammation were linked to it—though the study cannot say which factor caused the malnutrition.
Early-onset gout is associated with an increased risk of genitourinary cancers in a nationwide cohort of 6.5 million young Korean adults
A study of 6.5 million young Korean adults found that people with early gout were more likely to be diagnosed with genitourinary cancers later, but this does not prove gout causes cancer — it only shows a link. Gout is a type of arthritis caused by high uric acid, which can also harm kidneys.
Effects of GLP-1 receptor agonists on the incidence of contrast-induced acute kidney injury in patients with Type 2 diabetes mellitus undergoing coronary interventions.
This observational study found that type 2 diabetes patients who took GLP-1 drugs before heart procedures had less sudden kidney injury after contrast dye was used, but because it is not a randomized trial, it shows only a link—not proof the drug caused the benefit.
Low baseline HbA1c and reduced eGFR are associated with relatively unfavorable body recomposition after SGLT2 inhibitor therapy in type 2 diabetes.
In people with type 2 diabetes on SGLT2 inhibitors, those with lower blood sugar and worse kidney filtering rate (eGFR) at the start tended to lose more fat but also more muscle than others, which could matter for strength and recovery; this study shows a pattern, not cause-and-effect.
Metal Homeostasis Imbalance as Potentially Contributing Mechanism in Onset of Cardiac Disorders in Individuals with Chronic Obstructive Pulmonary Disease and Chronic Kidney Disease
This study looked at whether an imbalance of metals in the body, things like zinc, copper and iron, is linked to heart problems in people who have both chronic lung disease and chronic kidney disease. Damaged kidneys struggle to keep these metals in balance. The work shows an association only, not proof that metal imbalance causes the heart trouble. No abstract was available, so the size of the study is not known from this record.
Oxidative Stress and Renal Function in Severe Preeclampsia and Normal Pregnancy
This study compared kidney function and signs of cell damage from unstable oxygen molecules in women with severe preeclampsia against women with normal pregnancies. Preeclampsia is dangerous high blood pressure in pregnancy, and it can strain the kidneys. Because the two groups were only compared, this shows a link, not proof that the cell damage causes the kidney changes. No abstract was available, so the number of women studied is not known from this record.
Association of Serum 1,25-Dihydroxyvitamin D Levels with Erythropoietin Resistance Index-Based Relative Erythropoiesis-Stimulating Agent Hyporesponsiveness in Pre-Dialysis Chronic Kidney Disease
Many people with kidney disease get anemia, meaning low red blood cells, and take drugs that push the body to make more. Some people respond poorly to those drugs. This study checked whether a low level of the active form of vitamin D in the blood goes along with that poor response, in people who are not yet on dialysis. It is observational, so it shows a link, not proof that vitamin D is the reason.
Demographic and clinical characteristics of rapidly progressive glomerulonephritis in renal vasculitis in the Japan renal biopsy registry
Doctors in Japan pulled cases from a national registry of kidney biopsies, the small tissue samples taken to diagnose kidney disease. They described who gets a fast moving kidney inflammation driven by inflamed blood vessels, and how sick those people were at diagnosis. A registry review like this shows patterns, not cause. The patient counts are in the journal article and are not in this record.
A Circulating Proteomic Signature of Allostatic Load Is Associated with Multisystem Disease and Mortality
Researchers found a pattern of proteins in the blood that tracks with allostatic load, which is the wear and tear the body takes from long-term stress. People with that protein pattern were more likely to have disease in several organ systems and more likely to die during follow-up. This is an observational study, so it shows a link, not proof that stress caused the illness. People who are already sick can have both higher stress and these protein changes.
Association of adverse adulthood experiences with cardiovascular kidney metabolic syndrome
This study looked at hard experiences in adult life, such as abuse, money trouble, or losing a home. It checked whether people who went through more of them were more likely to have cardiovascular kidney metabolic syndrome, a cluster of heart, kidney, and blood sugar problems that travel together. The design is observational, so it shows a link, not proof that stress causes the syndrome. The size of that link is in the full article, not in this record.
