Pathophysiological Characterization of the Neuromuscular Function of a Population With Multiple Comorbidities Suffering From Chronic Renal Failure in Pre-dialysis. (PIONNIER)

March 23, 2020 updated by: Centre Hospitalier le Mans

The evolution of chronic kidney disease (CKD) causes a systemic upheaval on the body and a deep fatigue is very often described by patients (50-70% of the patients) even before the start of dialysis (pre-dialysis). This fatigue has many origins, and one of them probably stems from a deterioration of neuromuscular abilities. Very few studies have examined the physiological aspects of neuromuscular fatigue in pre-dialysis patients, and shedding light on potential deficits at this level would allow safe and efficient implementation of adapted physical activity programs.

Our study aims to characterize the pathophysiology of neuromuscular capabilities in chronic advanced renal failure in pre-dialysis patients.

Observational

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Chronic Kidney Disease (CKD) group:

Patients with chronic kidney disease and a glomerular filtration rate less than 60 ml/min of creatinine.

Control group:

The control group will consist of a group of people from the same age group as the CKD group but without chronic kidney disease. The exclusion criteria apply to this group. They will be selected from the spouses and other volunteers.

Description

Inclusion Criteria:

  • Adult patients (Age> 18 years) who have signed the informed consent form
  • Social security coverage
  • For patients in the Chronic Kidney Disease group: Glomerular filtration rate less than 60 ml/min of creatinine for more than three months

Exclusion Criteria:

  • Dermatological conditions of the upper limbs which would contra-indicate Electromyographic electrodes being positioned
  • Gestating women
  • Patients with known neuromuscular conditions
  • Patients with dementia
  • Patients with acute heart failure
  • Patients with a history of surgery of the evaluated limb
  • Patients included in an interventional study involving administration of treatments other than routine care
  • For the patients in the Chronic Kidney Disease group: patients currently undergoing dialysis or in a pre-dialysis program (e.g. with a dialysis fistula already in place).

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Chronic Kidney Disease (CKD) Patients
Patients with chronic kidney disease and a glomerular filtration rate less than 60 ml/min of creatinine. Patients will perform a hand grip fatigability test with their dominant hand, followed by a Timed Up and Go Test (TUG-Test), a Five-repetition sit-to-stand-test (5STS-Test) and a10 meters gait speed test.
Diagnostic test: Discrimination of neuromuscular alterations protocol
Patients will perform a hand grip fatigability test with their dominant hand, followed by a Timed Up and Go Test (TUG-Test), a Five-repetition sit-to-stand-test (5STS-Test) and a10 meters gait speed test.
Control cohort
The control cohort will consist of a group of people from the same age group as the CKD group but without chronic kidney disease. The exclusion criteria apply to this group. They will be selected from the spouses and other volunteers. This group will also perform a hand grip fatigability test with their dominant hand, followed by a Timed Up and Go Test (TUG-Test), a Five-repetition sit-to-stand-test (5STS-Test) and a10 meters gait speed test.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Neuromuscular evaluation of force.
Time Frame: 1 day
Maximum force normalized by body mass, measured by a hand grip test with the dominant hand.
1 day

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Psychometric evaluation of fatigue
Time Frame: 1 day
The Multidimensional Fatigue Inventory (MFI) is a 20 question self-report instrument designed to measure fatigue. It covers the following dimensions: General Fatigue, Physical Fatigue, Mental Fatigue, Reduced Motivation and Reduced Activity. Each question is graded from 1 ("Yes, that is true") to 5 ("No, that is not true"). Higher scores indicate a higher level of fatigue.
1 day
Quality of life impact of fatigue
Time Frame: 1 day

The functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) evaluates the impact on quality of life of chronic illness.

This is a questionnaire with 13 questions graded according to a Likert scale ranging from 1 to 5 (1 = quite, 5 = not at all).
1 day
Assessment of gait and balance
Time Frame: 1 day
The Timed Up and Go test (TUG) is a simple test used to assess a person's mobility and requires both static and dynamic balance. It measures the time that a person takes to rise from a chair, walk three meters, turn around, walk back to the chair, and sit down.
1 day
Assesment of lower limb functional strength
Time Frame: 1 day
The five-repetition sit-to-stand test (5STS) is a test of lower limb function that measures the fastest time taken to stand five times from a chair with arms folded.
1 day
Assesment of walking speed
Time Frame: 1 day
10 meters gait speed test: measure of the time required to walk 10 meters at the fastest speed possible.
1 day
Electromyographic evaluation: temporal recruitment of the motor units.
Time Frame: 1 day
The evolution of temporal recruitment through the evaluation of the discharge frequency of the motor units.
1 day
Electromyographic evaluation: Root Mean Square measurement
Time Frame: 1 day
The average Root Mean Square (RMS) evolution according to the progress of the fatigability protocol, and its link with the developed force.
1 day
