Effects of Pulmonary Rehabilitation in Hematopoietic Stem Cell Transplantation Recipients

Study Overview
=================
Brief Summary
-----------------
Stem cell transplantation is a process in which stem cells are harvested from either a patient's or donor's bone morrow or peripheral blood for intravenous infusion. Hematopoietic stem cell transplantation is a treatment with a high curative potential that may benefit a great number of patients with hematological, oncological, immunologic and hereditary diseases. In contrast, there are significant risks of chronic and acute complications due to conditioning regimens and immunosuppression, toxicity infections, graft versus host disease (GVHD) and inactivity including being bedridden. Patients undergoing hematopoietic stem cell transplantation are exposed to risk factors due to chemotherapy, whole body radiation, high dose corticosteroids, treatment-related inactivity, transplantation and GVHD-related muscle damage. Direct toxicity of the cardiovascular and musculoskeletal system (left ventricular dysfunction, pulmonary fibrosis) in relation to hematopoietic stem cell transplantation and secondary indirect physiological consequences of treatment such as exercise intolerance, sarcopenia are seen. In literature, there are few studies showing that aerobic exercise and resistance training applied during and after the transplantation process has positive effects on muscle strength and endurance, fatigue, functional performance, quality of life and physical activity. It has been shown in the literature that inspiratory muscle training in allogeneic hematopoietic stem cell transplant recipients increases functional exercise capacity, inspiratory and expiratory muscle strength, and reduces effort dyspnea perception, but the effects of inspiratory muscle training during transplantation have not been investigated. There are no studies showing long-term follow-up of comprehensive cardiopulmonary rehabilitation program during hematopoietic stem cell transplantation and which of these outcome measures are survival effect. Therefore, the investigators aimed to investigate the effect of cardiopulmonary rehabilitation on hematopoietic stem cell transplantation in terms of exercise capacity, respiratory and peripheral muscle strength, respiratory muscle endurance, respiratory function, physical activity level, fatigue, depression and quality of life effects and the effect of these outcome measures on survival.

Detailed Description
-----------------
According to sample size calculation 20 patients scheduled for hematopoietic stem cell transplantation will be included. Patients scheduled for hematopoietic stem cell transplantation will be evaluated four times; pre-transplantation, post-transplantation, 100th day after transplantation and 1st year after transplantation. Recipients will be randomized into study and control groups. Cardiopulmonary rehabilitation programme includes inspiratory muscle training, upper extremity aerobic exercise, progressive resistance training will be performed study groups. Upper extremity aerobic exercise and progressive resistance training will be performed control groups. Exercise capacity, physical activity, pulmonary functions, respiratory and peripheral muscle strength, respiratory muscle endurance, dyspnea and fatigue perception, depression and quality of life will be evaluated. Primary outcome measurements are exercise capacity and which outcome measures influence survival. Secondary outcomes are respiratory and peripheral muscle strength, respiratory muscle endurance, pulmonary functions, physical activity, dyspnea and fatigue perception, depression and quality of life.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Exercise training group<br>Inspiratory muscle, upper extremity aerobic exercise and progressive resistance trainings | Other: Exercise training group<br>* All exercise program will be applied during supervised session by a physiotherapist. Range of maximal heart rate will be screened by heart rate monitor during supervised session each day at patient's room. Inspiratory muscle training (threshold loading device (Threshold®- Inspiratory Muscle Trainer) at 20-30% of maximal inspiratory pressure (MIP)), upper extremity aerobic exercise training (arm ergometer, at 60-80% of maximum heart rate, dyspnea perception at 3-4 level as well as fatigue perception at 5-6 level according to Modified Borg Scale) and progressive resistance training (shoulder flexors, shoulder abduction and knee extensors at 4-6 level according to modified Borg scale) will be performed in the treatment group during acute hematopoietic stem cell transplantation process.<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Maximal exercise capacity | Maximal exercise capacity will be evaluated symptom limited cardiopulmonary exercise testing. Oxygen consumption will be measured by cardiopulmonary exercise test. The cardiopulmonary exercise test will be performed on the treadmill at a progressively increasing speed and grade. | Second day | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Respiratory muscle strength | Maximal inspiratory and expiratory muscle strength will be evaluated using mouth pressure device . | First day | 
| Respiratory muscle endurance | It will be evaluated incremental threshold loading test, in which participants started an initial load of 30% of maximal inspiratory pressure with a 10% increment every 2 minutes. | First day | 
| Peripheral muscle strength | Shoulder abduction and knee extensor muscle strength using portable hand held dynamometer, hand grip strength using grip dynamometer will be evaluated. | First day | 
| Pulmonary functions contains dynamic lung volumes | Pulmonary function tests will be performed using a spirometry according to the American Thoracic Society and European Respratory Society criteria. Forced expiratory volume in the first second (FEV1, (liter)) and (FEV1 (%)) , forced vital capacity (FVC (L)) and (FVC (%)), forced expiratory volume in the first second/forced vital capacity (FEV1/FVC (%)) , peak expiratory flow (PEF(L)), and (PEF (%)), and forced expiratory flow from 25 to 75 % (FEF25-75 %(L)), and (FEF25-75 % (%)) will be expressed as the liter and percentages of the predicted values. | First day | 
| Physical activity | Physical activity will be evaluated multi sensor activity monitor for 4 consecutive days. | First day | 
| Fatigue | Fatigue Severity Scale (Turkish version) - Fatigue Severity Scale (FSS) is a self-reported questionnaire. FSS evaluates patient's fatigue severity. This questionnaire includes 9 items and score range for each item from 1 to 7 point (7-point Likert scale). Fatigue Severity Scale score is calculates by deriving an arithmetic mean. Cut-scores of over 4 are indicative of significant fatigue (higher scores show more severe fatigue). | First day | 
| Depression | Beck Depression Inventory (Turkish version) - Beck Depression Inventory (BDI) is a self-reported questionnaire. BDI evaluates patients' depression level. This questionnaire includes 21 items. Each item scores from 0 to 3 point (higher scores shows patient ). The BAI scores are classified as depression over 17 points. | Second day | 
| Survival | Kaplan-meier survival analysis will be calculated at 100th day and first year. | 100th day and first year | 
| Functional exercise capacity | Functional exercise capacity will be evaluated with 6-minute walking test according to the ATS and ERS criteria. | First day | 
| Disease Specific Quality of Life | Quality of life was measured using Turkish version of European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 version 3.0 (EORTCQLQ) which is widely used as health related quality of life questionnaire in cancer patients. The cancer-specific questionnaire has 30 questions and incorporates five functional scales, three symptom scales, a global health status and several single items. All item scores are transformed to 0-100. Higher values indicate higher functional/healthy level in functional scales, a higher quality of life level in global health status and increased symptoms in symptom scales. | First day |
