Brief Summary

Chronic kidney disease (CKD) patients receiving hemodialysis treatment (CKD stage 5) suffer from a variety of co-morbid diseases, many of which may be mechanistically linked. Protein malnutrition, muscle catabolism and wasting are especially common, and these lead to reduced muscle strength, declines in physical function, and low levels of physical activity. Physical inactivity exacerbates these functional declines, and also promotes cardiovascular disease (CVD) and bone disorders. This cycle of disease and disability greatly reduces quality of life (QOL) and increases mortality rates in dialysis patients. Many factors contribute to the development of these co-morbidities. Chronic inflammation is believed to be a cause and a consequence of the protein malnutrition, CVD and bone disorders in dialysis patients. In addition, abnormalities in mineral metabolism resulting from the deficit in kidney function promote the loss of mineral from bone and the deposition of mineral in the vasculature, a process termed vascular calcification (VC). VC is associated with a variety of CVD-related disorders, including arterial stiffness, increases in arterial wall intima-media thickness (IMT), left ventricular hypertrophy (LVH), and declines in cardiac function. As a result of these abnormalities, cardiovascular events are 10 to 30 times greater in dialysis patients than in age- and sex-matched subjects in the general population.

Outcome Measures

Primary Outcomes (1)

  • Examine the effects of intradialytic oral protein supplementation and exercise training on physical function.

    Physical function, as assessed by a shuttle walk test, will improve in PRO+EX and PRO, compared to CON, and the magnitude of improvements will be greatest in PRO+EX. In secondary analyses, we also will examine the effects of our interventions on other variables related to physical function, including lean body mass, muscle strength, and activities of daily living (ADL) assessments.

    12 months

Secondary Outcomes (2)

  • Examine the effects of intradialytic oral protein supplementation and exercise training on CVD risk.

    12 months

  • Examine the effects of intradialytic oral protein supplementation and exercise training on bone health as determined by bone mineral density (BMD).

    12 months

Study Arms (3)

Control

SHAM COMPARATOR

This group of patients will receive a non-nutritive beverage, and no exercise.

Dietary Supplement: Control

ACTIVE COMPARATOR

This group of patients will ingest 30 grams of a liquid whey protein supplement during the first hour of their dialysis session

Dietary Supplement: Protein

Protein + Exercise

ACTIVE COMPARATOR

This group will ingest 30 grams of a liquid whey protein supplement as well as exercise for 30-45 minutes during their dialysis treatment

Behavioral: Protein + Exercise

Interventions

ControlDIETARY_SUPPLEMENT

A placebo non-nutritive beverage will be administered before dialysis sessions 3 times per week.

Control
ProteinDIETARY_SUPPLEMENT

A whey protein beverage will be administered before dialysis sessions 3 times per week.

Eligibility Criteria

Age30 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Must receive hemodialysis treatment at least 3 days per week.
  • Must be ≥ 30 years of age.
  • Must be willing to be randomized to the control or intervention groups.
  • Must be physically able to exercise (e.g., no orthopedic problems that would preclude them from cycling during dialysis).
