Novel Treatment Ameliorates Proteinuria and Dyslipidemia in a Model of Noninflammatory Glomerular Disease
 Novel Treatment Ameliorates Proteinuria and Dyslipidemia in a Model of Noninflammatory Glomerular Disease 150 150 Lauren Dembeck
By: Lauren Dembeck

Idiopathic nephrotic syndrome — characterized by proteinuria, hypoalbuminemia, dyslipidemia, and edema — is one of the most common pediatric glomerular diseases. Glucocorticoids are first-line treatment, followed by calcineurin inhibitors for steroid-resistant disease; however, currently available calcineurin inhibitors can have numerous side effects, including dyslipidemia, and require frequent monitoring of drug levels in the blood. Since…

What Drives Nephrotic Syndrome Hypercoagulopathy?
 What Drives Nephrotic Syndrome Hypercoagulopathy? 150 150 Mary Bates, PhD
By: Mary Bates, PhD

Antithrombin deficiency does not play a major mechanistic role in the increased clotting risk of nephrotic syndrome, according to a new study. Patients with nephrotic syndrome are at risk for life-threatening venous thromboembolism complications. This risk is thought to be driven by an acquired hypercoagulopathy, or excessive blood clotting. Although the mechanisms underlying this hypercoagulopathy…

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

By: Lauren Dembeck

A little-studied peptide found in the urinary tract is a potential biomarker for urinary tract infection risk and could be developed into a novel therapeutic against drug-resistant bacteria.  Researchers at Nationwide Children’s Hospital have demonstrated that an understudied protein expressed in the human kidney and bladder kills the bacteria that cause urinary tract infections (UTI).…

An electronic self-administered bleeding assessment tool is a time-saving measure to comprehensively evaluate a pediatric patient’s bleeding symptoms. Bleeding assessment tools (BATs), originally developed as research tools, are used clinically to comprehensively evaluate a patient’s bleeding symptoms. Along with clinical judgement, “BATs are used to discriminate between patients who do and do not have a…

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

By: Mary Bates, PhD

In a preclinical mouse model, researchers identify the immune cell balancing act that determines whether renal scarring will occur following kidney infection More than half of urinary tract infections in children spread from the bladder to the kidneys, causing acute kidney infections that can lead to renal scarring. Renal scarring can have serious repercussions in…

 What Are the Clinical Implications of Crescentic Glomerulonephritis? 1024 732 Abbie Miller
By: Abbie Miller

The Pediatric Nephrology Research Consortium’s most recent study investigates the risk factors for disease progression in children with glomerulonephritis and crescents on kidney biopsy. In patients with glomerulonephritis (GN), the histopathology of the kidney may include crescents, which result from extra-capillary proliferation of cells within the glomerulus. A recent study from the Pediatric Nephrology Research…

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
By: 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…

 Determining Ureteropelvic Junction Obstruction Surgical Success Using Biomarkers 1024 575 Katie Brind'Amour, PhD, MS, CHES
By: Katie Brind'Amour, PhD, MS, CHES

Biomarkers initially found to differ among patients with ureteropelvic junction obstruction and healthy controls may also objectively gauge post-surgical resolution of obstruction. A follow-up study of a trial that initially identified four biomarkers that differ between healthy controls and pediatric patients about to undergo surgery for ureteropelvic junction obstruction (UPJO) has confirmed that two of…

 Transforming Medical Science Through Research Affinity Groups 150 150 Katie Brind'Amour, PhD, MS, CHES
By: Katie Brind'Amour, PhD, MS, CHES

Purposeful synergy drives the most meaningful medical science. Nephrology physician-scientists require tissue samples, urologists desire tests to know which patients truly require surgery, and basic scientists must find ways to meaningfully assess new animal models to yield clinically valuable data. If each of these professionals had a defined network of colleagues from the other disciplines…

A positive fluid balance is associated with acute kidney injury and worse outcomes in a new study of premature infants. According to new research, there is an association between fluid balance and outcomes in preterm newborns, with a negative fluid balance during the first week of life emerging as a potential therapeutic target. Premature infants…

Uroplakin Plaque Key to Protecting Kidney During Urinary Tract Obstruction
 Uroplakin Plaque Key to Protecting Kidney During Urinary Tract Obstruction 150 150 Kevin Mayhood
By: Kevin Mayhood

Plaque appears to help remodel urothelium, allowing kidney to hold excess urine without damage, Urinary tract obstruction (UTO) is the leading cause of chronic kidney disease and end-stage renal disease in children. But the extent of damage caused by obstruction differs from child to child. Researchers at Nationwide Children’s Hospital studying why suggest that uroplakin…

If asthma development in people parallels mice, the cells’ mechanisms may provide a target for disease prevention. A subtype of neutrophil, labeled CD49d+ PMN, which is necessary to drive asthma and allergies in a mouse model, also accumulates in the nasal fluid of people with symptoms of an upper respiratory viral infection, researchers have discovered. Neutrophils are…

Insulin regulates an antimicrobial peptide that is suppressed in patients with diabetes. A recent study led by clinicians and researchers at Nationwide Children’s Hospital reports a potential explanation for why urinary tract infections (UTIs) are so common in patients with diabetes – insulin regulates an antimicrobial peptide (AMP) that is suppressed in those patients. Patients…

Fibrosis is an unmet medical challenge with no satisfactory test and insufficient therapy. Now, one naturally occurring cellular component could simultaneously diagnose and heal patients. It’s much more than a million-dollar idea. The person who invents a simple blood or urine test that can accurately measure the severity of scarring in internal organs will have…
