Examining the Impact of High-protein Oral Supplement on Protein Status of Adults on Peritoneal Dialysis

Study Overview
=================
Brief Summary
-----------------
This is a 6-month prospective interventional clinical trial designed to evaluate the impact of whey protein isolate oral supplement on protein status. Differences in protein status will be evaluated with review of the medical chart from standard of care monthly blood collection for serum albumin, total protein, and normalized protein catabolic rate (nPCR) as detected by serum urea nitrogen. Mid-arm circumference and weight will be measured to ensure no significant changes. Quality of life will be measured to detect if the addition of protein aided in overall quality of life. There will be a 3-month recruitment period prior to the start of the trial to ensure the potential participants are familiarized with the clinical trial. After the recruitment period has finished, eligible participants will sign the consent form in order to participate in the study. At this point, participants will be provided the supplements for the month and instructed with the amount of water and how to mix with the provided measuring and drinking cup.

Design Details

Primary Purpose: Supportive Care
Intervention Model: Single Group Assignment
Interventional Model Description: 6-month prospective interventional clinical trial
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Whey protein consumption<br>Participants will receive 20g total protein of whey protein isolate in 115 mls of water to consume daily for up to 6 months | Dietary Supplement: Whey protein supplement<br>* A monthly supply of 35 g of whey protein isolate will be provided to participants in individual sachet packets with instructions of preparation. Every month, participants will come to the center to provide the standard monthly blood sample. At this time, the PI will have participants complete the quality-of-life instrument, ask if there have been any changes in their dietary habits, and collect weights for up to 6-months. Additionally, participants will indicate if they had consumed the protein daily and/or bring back their empty/full satchel packets. As this is a feasibility trial, it is necessary to determine the compliancy of consuming protein daily and the amount. Furthermore, understanding how protein markers may be affected by consumption of the protein daily vs less frequently throughout the week is important to establish improved recommendations for consumption of protein supplements.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Serum albumin | Collection of serum albumin to identify a change from pre-post to analyze the effect protein isolate had on inflammation marker and protein status. | up to 6 months of the study | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Total protein | Collection of whole blood total protein to identify a change from pre-post to analyze the effect protein isolates had on protein stores. | up to 6 months of the study | 
| normalized protein catabolic rate (nPCR) | Collection of nPCR through serum to identify a change from pre-post to analyze the effect protein isolates had on nPCR. | up to 6 months of the study | 
| mid-arm muscle circumference | measuring mid-arm circumference from baseline to the end of the study to determine that protein isolates did not affect muscle mass. | up to 6 months of the study |
