Accessible and affordable dialysis for children in developing countries


Children living outside industrialized nations have limited access to health care, and many children with severe kidney dysfunction do not have access to dialysis. Some developing countries have access to manual peritoneal dialysis, which requires the placement of a catheter into the abdominal cavity every one to two hours, 10 hours per day. But supplies are expensive, and many countries lack the infrastructure needed to get large quantities of dialysis fluid to children’s homes.

At the recent 2015 Boston Children’s Hospital Global Pediatric Innovation Summit + Awards, pediatric nephrologist Sara Jandeska, MD, of Rush Children’s Hospital in Chicago, pitched a portable, affordable solution: providing just the dialysis salts.

Decoding kidney disease, one gene at a time

Part 2 of a two-part series on kidney disease. Part 1 is here.

Friedhelm Hildebrandt, MD, receives around one blood sample in the mail per day from a patient with chronic kidney disease. Over 10 years, he’s collected more than 5,000 samples from patients all over the world—in hopes of finding the genetic mutations that cause them and, ultimately, new treatments.

Consider the mutation in an 8-month-old boy from Turkey, who had fluid collection under his skin and elevated protein in his urine—signs that his kidneys were failing. Doctors identified his disease as a form of nephrotic syndrome, one of the three main types of chronic kidney disease. The disease was proving to be hard to treat: Ten weeks of steroids had produced no result, and an immunosuppressant hadn’t been effective enough to justify its harsh side effects.

Only within the last year, genetic research has revealed that more than 30 percent of childhood chronic kidney diseases—like this child’s—stem from single mutations in single genes.

Test licensed for devastating kidney disease

A glomerulus (Gray's Anatomy)

Focal segmental glomerulosclerosis (FSGS) is the second leading cause of kidney failure in children. It ruthlessly attacks the kidney’s filtering system: The glomeruli, tiny clusters of capillaries within each nephron that filter toxins from the blood, scar, harden and stop working. Patients are forced onto chronic dialysis and, all too often, need a kidney transplant.

“To make matters worse, many patients have recurrence of the disease soon after transplant,” says William Harmon, MD, chief of Children’s Division of Nephrology. “First it ruins your native kidney, then it can return instantly in the transplant and ruin that also.” Amazingly, this can sometimes happen within hours of transplantation.
