About

The purpose of the current investigation is to provide proof of concept for a future approach to improve UF prediction accuracy. While building on the ideas of the past, the concept is augmented by leveraging additional diagnostic technologies and digital data analytics methodologies.

Full description

The primary objective of this study is:

- UFV determined per defined dwells with variable dwell duration, dialysis fluid glucose composition and inflow volumes

The secondary objectives of this study are:

• Mean daily UFV
• Defined laboratory parameter like urea, creatinine, glucose, sodium determined in blood and dialysate during the extended PET (in dialysate additionally determination: phosphate, albumin removal)
• Treatment parameter: performed treatment duration and volume
• Fluid status measured by Body Composition Monitor (BCM)
• Manual IPP determination during the extended PET: At the first half of the dwell (during the first hour) for every 20 min and during the second half after 2h, 3h and 4h dwell time
• Residual renal function (RRF): renal urea and creatinine clearance, 24h urine output, Glomerular filtration rate (GFR)
• Extended PET
• 24 h batch collection (including e.g. total peritoneal clearance)
• Analysis of daily dietetic fluid intake, weight and further parameters documented by the patient in a patient diary

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

• Participation in an interventional clinical study during the preceding 30 days
• Previous participation in the same study
• APD patients having dwell exchanges throughout the day ("day dwell")
