Lupus Clinic

Lupus is a chronic and heterogeneous autoimmune disorder that can affect any organ in the body. Uncontrolled lupus can cause severe complications including kidney damage from lupus nephritis and psychosis, seizures, stroke and cognitive problems from central nervous system involvement. Our nephrologists work closely with the rheumatologists in the Lupus Clinic to ensure that patients with lupus receive the critical kidney care they need.

Conditions We Treat

Nephrotic Syndrome in Children

Nephrotic syndrome is characterized by symptoms that result from changes that occur to the small, functional filters in the kidneys.

Brothers Sitting Outside Smiling


Glomerulonephritis is a kidney disease that involves inflammation of tiny filter units in the kidneys called glomeruli. Due to inflammation, these filters can leak blood and protein into the urine. Symptoms may include dark brown-colored urine (from blood and protein) and diminished urine output.

Name: Kaylor B.
Condition(s): Nephrotic Syndrome
Age Today: 13 Years

About a month before Kaylor's 5th birthday, he developed an upper respiratory infection. During a visit to the doctor, I noticed when they took his weight it had spiked up 10 pounds, but I couldn't remember the last time I weighed him.

Read Kaden's Story

Name: Kaden S.
Condition(s): Dilated Cardiomyopathy, Neurogenic Bladder
Age Today: 12 Years

Though Kaden was fully potty trained at 3 years of age, we gradually started noticing urinary incontinence and his fluid intake was getting excessive. We asked his primary care physician for blood work and within 2 hours we were notified that Kaden's creatinine was 3 times what it should be. They advised us to go to Nationwide Children's Hospital and that is how Kaden's journey of Stage 4 kidney disease began.

The Pediatric Nephrolgy Research Consortium (formerly the Midwest Pediatric Nephrology Consortium - MWPNC)

The Pediatric Nephrology Research Consortium (PNRC) started in 2004 as the Midwest Pediatric Nephrology Consortium  with a mission to develop and execute multi-center clinical and translational studies related to pediatric kidney diseases. As the Consortium has expanded to include participants from 90 pediatric nephrology centers across North America, it has truly outgrown its ‘mid-western’ roots.  With over 200 members, it continues to be an active continent-wide platform for collaborative research by investigators dedicated to developing the evidence for the best standards of care for children with kidney disorders. The PNRC has published now published over 50 peer-reviewed manuscripts and conducted 12 nationally funded research projects. Through these efforts, the PNRC is re-making the way that pediatric nephrologists improve patient care through collaborative clinical research. John D. Mahan, MD, and William E. Smoyer, MD, are two of its founders and Dr. Mahan serves currently as Chairman of the Board of Directors of the PNRC.
