Detailed Description
Chronic kidney disease patients with end-stage renal disease require regular hemodialysis (HD) therapy 3-4 days per week to filter their blood of toxins/waste and to remove excess fluid. HD therapy is essential for survival in patients with kidney failure, but the dialysis process is inefficient and does not remove all of the fluid and waste products that accumulate in patients since their last treatment. The inefficiency of dialysis, coupled with excessive dietary sodium and fluid intakes, results in a high prevalence of chronic volume overload (VO) and VO dependent hypertension (HTN). Both VO & HTN can have adverse effects on the heart and arteries, eventually lead to enlargement of the heart and cardiac dysfunction (1-3).
Dialysis care providers (doctors, dietitians, technicians) provide regular counseling for patients to reduce their dietary sodium and fluid intake, despite widespread non-adherence and the high prevalence of both VO and hypertension. Research interventions to increase dietary education and support behavior change have also demonstrated low efficacy in the dialysis patient population. Many barriers and factors contribute to excessive dietary sodium intakes and poor dietary adherence, thus is appears that current dietary education strategies may not be robust enough to change patient behaviors. However, a recent study in heart failure patients demonstrated that home-delivered meals represent a unique opportunity alter outpatient dietary practices. Patients with multiple comorbidities and numerous dietary behaviors, such as those on renal replacement therapy, may need additional support to establish and maintain dietary changes.
The purpose of this study is to compare dietary counseling with renal home meal delivery on clinical outcomes relating to both VO & HTN. This trial is a comparative-effectiveness mixed-models design. In this study, patients will be randomized to one of two study arms: 1) CON (7 months total) where patients receive usual care (eating their normal diet) for the first 5 months of the study. This will be followed by a 2-month period where they will receive home-delivered meals and additional dietary counseling to reduce sodium intake; OR 2) INT (5 months total), where patients will receive home-delivered meals plus additional dietary counseling for the first 2 months of the study, followed by 3 months of continued counseling. During the home-meal delivery periods, participants will be provided a low-sodium/renal diet that includes receiving 2 meals per day during their 1st month, and 1 meal per day during the 2nd month (month 6 and 7 for CON; and month 1 and 2 for INT). The meals will be delivered to the participant's homes each week by momsmeals.com.
We are also plan to collect sensory taste data to characterize patients on dialysis preferences for salt. It is possible that a low sodium diet may change these preferences, so that patients desire more low-sodium tasting food. This information would allow us to analyze how dialysis patients salt intake is associate with taste preference with salt and how this relates to clinical outcomes. The study outcomes include: clinical outcomes (hospitalizations, treatment efficiency), cardiovascular measures (blood pressure, cardiac output, and vascular resistance) and fluid/hydration status (total body water, extracellular fluid) using bioelectrical impedance.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: Control
Participants will follow their usual or normal diet for 5 months (CON) followed by an Controlled Dietary Sodium Restriction (INT) diet for 2 months.
During the sodium restricted diet, participants will be provided with 2 meals and snacks daily, for 30 days (Month 5 - days 1-30) and 1 meal and snacks daily, for 30 days (Month 6 - days 31-60).
These meals should meet the National Kidney Foundation's Kidney Disease Outcomes Quality Initiative (KDQOI) guidelines for energy and protein (30-35 kcal/kg & 1.2 g/kg) as well as low phosphorus, potassium, and sodium.
The meals are formulated to less than 600-800 mg sodium each (<2,000g/day) and will be ordered and delivered through momsmeals.com

Measure Description |
Time Frame |
---|---|---|
Assessing Interdialytic weight gain (IDWG) using bioelectric impedance spectroscopy device (BIS)
Time Frame: Five months
|
The research team will assess patients hydration status by using a non-invasive Cardiac System (NICaS) bioelectric impedance spectroscopy device (BIS) that will focus on noninvasive assessment and monitoring of cardiovascular, respiratory, and fluid parameters.
The system provides real-time data on various parameters of a patient's cardiac and vascular functions.
NICaS is a method of Impedance Cardiography (ICG) which utilizes dual impedance electrodes (about 3''x3''), placed on two limbs, preferably one on the wrist and the other on the contralateral ankle (any combination may work).
NICaS measurements include the cardiac output and its derivatives, as well as an assessment of the left ventricular cardiac contractility.
This device will be used to measure fluid retention between treatments.

Blood Pressure - markers of cardiovascular risk
Time Frame: Five months
|
The research team will use an IntelliSense® Blood Pressure Monitor to measure blood pressure accurately prior to dialysis treatment in quiet conditions with participants sitting rested for approximately 10 minutes.
This measurement will take less than 2 minutes total to complete.
The systolic blood pressure (mmHg) and diastolic blood pressure (mmHg) will be collected for this outcome.

Dietary Recalls using ASA24
Time Frame: Five months
|
The research team will meet with each study participant to go over weekly nutrition education.
Topics will include various activities such as reading a nutrition label, identifying 'high sodium' and 'low sodium' food content at grocery stores, introduction to 'low sodium' recipes, and cooking with alternative salt-free spices.
In addition, the research team will use the Automated Self-Administered 24-hour (ASA24) Dietary Assessment Tool to assess diet recalls.
The ASA24 is a web-based tool that enables multiple, automatically coded self-administered 24-hour recalls and/or multi- day food records also known as food diaries.
The National Cancer Institute (NCI) provides ASA24 to the research community at no cost.
Diet recalls will serve to document the change in sodium intake through the duration of the study.
The sodium content (mg) of the food participants eat will be used for this outcome.
