UI Researchers' Study Compares Kidney Dialysis Methods

A team of researchers at University of Iowa Hospitals and Clinics is conducting a study that may help determine if a particular approach to dialysis treatments might be more beneficial for some patients with kidney disease.

The team is studying a dialysis method called nocturnal home hemodialysis or, more simply, overnight hemodialysis. Patients often receive dialysis treatments in centers based in hospitals or their communities. Some may receive dialysis in their own homes during their waking hours.

Nocturnal home hemodialysis occurs in the patients' homes while they sleep. Kidney specialists say it appears that overnight hemodialysis may offer some advantages.

"There are indications that people who learn how to perform nocturnal home hemodialysis may need fewer medications, experience fewer adverse symptoms, enjoy a better quality of life and could even live longer," explained John Stokes, M.D., the principal investigator of the study at UI Hospitals and Clinics. "We are conducting this research trial to see if those observations are valid."

Researchers at a dozen dialysis centers in North America plan to enroll about 250 participants in the study, including 20 at UI Hospitals and Clinics. Over the course of a year, participants will be randomly assigned to receive either conventional dialysis treatments in their homes three times a week while awake, or overnight dialysis sessions while they sleep six times a week.

For more information about the nocturnal home hemodialysis study, contact the UI Home Dialysis Unit at 319-356-4003, or call 319-356-8252 and ask to speak with Stokes or Douglas Somers, M.D.
