The Effect of Nighttime Dialysis on the Inflammation of Kidney Failure

This study will determine whether a new form of home hemodialysis carried out at night during sleep reduces blood levels of hormone-like substances called cytokines that may cause fatigue and increase blood fats and sugar. Participants will stay twice in the Rockefeller Hospital and receive a standard diet and blood testing. Training for nocturnal hemodialysis will be provided at the nearby Manhattan Dialysis Center of The Rogosin Institute, affiliated with The Rockefeller University.

Patients treated with conventional hemodialysis for at least 3 months and interested in learning home nocturnal hemodialysis will be screened in the Rockefeller Outpatient Research Center. If eligible, during the first 8 day hospital stay, participants will receive a standard diet and dialysis treatment nearby at the Rogosin Institute Dialysis Center. During the last 2 days, their blood will be frequently sampled for cytokines, fats and sugar. Dialysate will also be sampled. They will have the same diet and tests repeated during a second admission after either 4 months of conventional dialysis or 1 month training for nocturnal dialysis followed by 3 months of home nocturnal dialysis (randomized 1:1). After the second admission, patients treated with conventional dialysis will be discharged from the study and trained in nocturnal hemodialysis. Off-site computer monitoring will be utilized when patients dialyze themselves at home or during the admission in The Rockefeller University Hospital.
