Conditions
Chronic Kidney Disease Requiring Chronic Dialysis

Behavioral: Intradialytic resistance training
Registration Number
NCT03511924
Lead Sponsor
Pavol Jozef Safarik University
Brief Summary

The study will investigate the effects of an intradialytic resistance training on miRNA´s expression and muscle strength in haemodialysis patients.

Detailed Description

Chronic kidney disease (CKD) is accompanied by distortions of immune functions and acceleration of inflammation processes. Regular exercise has shown great potential for improving the health-related parameters of CKD patients. Moreover, muscle strength is considered to be an important predictor of protein- and energy- wasting, inflammation, quality of life and mortality in CKD patients. The behaviour and individual variability of adaptation to regular, controlled, supervised physical activities in CKD patients are not well defined and understood. The understanding of molecular adaptation mechanisms, represented by the epigenetic impact of exercise on renal specific miRNA´s expression, is necessary for future improvements in clinical practice. Monitoring pro- and anti-inflammation genes activity, their transcription factors and expression of miRNA molecules (influencing the signalling pathways of specific genes) will enable us to draft a new transcription and translation model for exercise-induced adaptation in CKD patients. Additionally, our results will indicate the clinical value of selected markers for the diagnostics and prognostics of disease.

GroupInterventionDescription
Intradialytic resistance trainingIntradialytic resistance trainingDuring the 12-week intradialytic training plan subjects will be performed 3 to 5 sets of 3 different lower extremities exercises, each set will consist of 12 up to 18 repetitions of a single exercise. Subjects will take 1 to 2 minutes rest between each set. The resistance training will be realized 3 times per week and will be performed during haemodialysis therapy.
Primary Outcome Measures
NameTimeMethod
Change in lower extremity muscle strengthBefore the intervention, 1-5 days after the completion of the 12-week intervention and after 3 months follow up

Change in maximal voluntary force produced during knee extension, leg flexion, extension and hip abduction, adduction will be assessed by dynamometer

Secondary Outcome Measures
NameTimeMethod
Change in activity of circulatory miRNA molecules involved in TRIM63 and IGF-1 signalling pathwaysBefore the intervention and 1-5 days after the completion of 12-week intervention

Blood plasma will be collected for miRNAs analysis. We will analyze the activity of miRNAs involved in TRIM63 and IGF-1 signalling pathways for better definitions of chronic renal insufficiency and muscular adaptation following progressive resistance training. For miRNA analysis, we selected circulatory miRNA´s which were previously connected with regulation of calcium metabolism, calcification processes, protein-energy wasting, muscle mass and functions

Change in renal specific clinical dataBefore the intervention, 1-5 days after the completion of the 12-week intervention and after 3 months follow up

Clinical data will be collected from the medical documentation of patients. The extracted database will contain patient´s nephrological diagnosis profile, data about the presence of other diagnosis and comorbidities, body composition parameters and standard dialysis biochemistry, haematology and dialysis adequacy measures.

Change in score on the Hospital Anxiety and Depression ScaleBefore the intervention and 1-5 days after the completion of 12-week intervention

The Hospital Anxiety and Depression Scale (HADS) will be used to assess states of depression and anxiety in the setting of a hospital medical outpatient clinic. The HADS consists of two subscales, subscale for anxiety and subscale for depression. Both subscales contains seven items and each item is rated on a four-point scale (numeric score range from 0 to 3 points). Maximal score for both subscales is 21, minimal score is 0. Scores of 11 or more on either subscale are considered to be a significant indicator of psychological morbidity. Scores between 8 and 10 represents "borderline" and scores between 0 and 7 represents "normal" indication of anxiety and depression.

Change in score on the Kidney Disease Quality of LifeBefore the intervention and 1-5 days after the completion of 12-week intervention

Kidney Disease Quality of Life (KDQOL™) instrument will be used to assess generic and kidney-disease targeted aspects of quality of life (self-rated health, self-rated change of health status, physical and mental component) of patients on haemodialysis.
