Novel Compound Shows Promise for Treating Nephrotic Syndrome
Novel Compound Shows Promise for Treating Nephrotic Syndrome 1024 575 Mary Bates, PhD

PPARγ selective modulator appear to be more efficacious in reducing proteinuria and comorbidities, and has fewer side effects than a traditional PPARγ agonist in a preclinical model of nephrotic syndrome. Nephrotic syndrome, characterized by high proteinuria, is one of the most common forms of glomerular disease. It is typically associated with edema, hypercholesterolemia, hypoalbuminemia, systemic…

Identifying Which Children with Nephrotic Syndrome Will Respond to Steroids 1024 683 Mary Bates, PhD

New research identifies potential biomarkers in the plasma of children with steroid resistant nephrotic syndrome. Nephrotic syndrome is among the most common forms of kidney disease in children. Although glucocorticoids (i.e., steroids) are the primary treatment, approximately 10 to 20% of children with nephrotic syndrome present with or develop steroid resistance. This is only discovered…

Identifying Early Urinary Biomarkers of Kidney Damage in Type 1 Diabetes
Identifying Early Urinary Biomarkers of Kidney Damage in Type 1 Diabetes 1024 575 Mary Bates, PhD

Markers of renal tubule injury and oxidative stress indicate diabetic nephropathy before microalbuminuria. Diabetic nephropathy is a common complication of type 1 diabetes. Traditionally, measurement of microalbuminuria is used to screen children with diabetes for diabetic nephropathy. However, evidence suggests that damage to the kidneys may begin soon after diagnosis, much earlier than microalbuminuria can…

Does Twinkle Artifact on Ultrasound Indicate a Kidney Stone in Pediatric Patients? 150 150 Mary Bates, PhD

The presence of twinkle artifact on ultrasound is a useful, though imperfect, tool for diagnosing kidney stones in children. For pediatric patients, ultrasound is the recommended imaging modality used to diagnose kidney stones.

Keeping in Touch: Renin-Producing Cells Require Cell Adhesion Molecule to Survive 1024 575 Lauren Dembeck

Uncovering the molecular mechanisms underlying the renin-angiotensin-aldosterone system may provide insights into the long-term effects of hypertension and antihypertensive medications.  As the main source of renin in the human body, juxtaglomerular (JG) cells are crucial for blood pressure and fluid-electrolyte homeostasis. However, these cells cannot be cultured in vitro, making it challenging to study the…

Incidence and Impact of Acute Kidney Injury in Patients With Hypoplastic Left Heart Syndrome 150 150 Abbie Roth

While incidence of severe kidney injury after surgery for hypoplastic left heart syndrome is low, it may be linked to increased 30-day mortality. Acute kidney injury – the abrupt decline of renal function – following pediatric heart surgery leads to worse outcomes, including increased mortality. The overall incidence of acute kidney injury (AKI) after pediatric…

Novel Roles of the Urothelium in the Development of Congenital Anomalies of the Kidney and Urinary Tract
Novel Roles of the Urothelium in the Development of Congenital Anomalies of the Kidney and Urinary Tract 150 150 Lauren Dembeck

In addition to genetic defects, interactions of the developing urothelium with its underlying mesenchyme and superficial plaque may contribute to congenital anomalies of the kidney and urinary tract. Congenital anomalies of the kidney and urinary tract (CAKUTs) are the leading cause of chronic and end-stage kidney disease in children. Collaborative translational research at Nationwide Children’s…

Can a Kidney Failure Risk Equation Validated in Adults Predict Kidney Failure in Children?
Can a Kidney Failure Risk Equation Validated in Adults Predict Kidney Failure in Children? 1024 575 Lauren Dembeck

Novel disease-specific biomarkers are needed to improve prediction models in pediatric disease. Obstructive uropathy is a frequent cause of kidney injury in children, and it is estimated to cause approximately one-sixth of pediatric kidney failure cases in North America. However, risk equations to predict kidney disease progression have not yet been developed for children. To…
