Exercise Training Program

BACKGROUND: Interstitial lung disease is characterized by exertion dyspnea, exercise limitation and reduced quality of life. The role of exercise training in this diverse patient group is unclear. The growth differentiation factor 15 (GDF15) is a stress-sensitive circulating factor that regulates systemic energy balance and could be a possible biomarker in interstitial lung disease. OBJECTIVE: To evaluate the effect of supervised exercise (endurance and resistance) training (SET) on exercise capacity, pulmonary function parameters and GDF15 levels in patients with interstitial lung disease (PwILD). METHODS: In this non-randomized case-control trial, the experimental group comprised of 10 PwILD (7 women and 3 men) while the control group consisted of of 18 apparently healthy participants s 11 women and 7 men). All subjects completed an 8-week supervised exercise training program, at a rate of twice a week. Dyspnea was evaluated using the Shortness of Breath Respiratory Questionnaire. Exercise capacity was measured using the 6-min walk test while the heart rate (HR) was monitored before and after the exercise training. GDF15 levels were measured by Enzyme-Linked Immunosorbent Assay (ELISA). RESULTS: PwILD had significantly shorter 6-min walk distance than the control subjects at both the 1st and the 15th visit. However, both groups improved significantly in this test. The change (pre to post-exercise) in HR value was smaller in PwILD compared to the controls. Moreover, PwILD had higher Shortness of Breath Respiratory Questionnaire score than controls. While the mean pre-post GDF15 change values in both groups remained statistically unchanged the GDF15 values of the PwILD patients were significantly higher compared to the controls with respect to pre-post exercise training respectively. CONCLUSION: Supervised exercise training did not affect GDF15 levels in both patient and control groups but its values in PwILD were significantly higher compared to those of controls (p⩽0.05). The exercise capacity and dyspnea in these patients improved after exercise training program.

The Impact

Objectives: To assess the impact of supervised exercise training (SET) on pulmonary function Parameters, exercise capacity and Irisin biomarker in Interstitial Lung Disease (ILD) patients. Methods: Ten (10) patients with ILD and 18 healthy controls of age between 30-40+ years were selected for 8-weekSET program. Before and after SET all subjects performedexercise capacity six minutes’ walk test (6MWT), heart rate (HR) changes were recorded, shortness of Breath Respiratory Questionnaire (SOBQ) was obtained and Irisin levels were measuredby Enzyme-Linked Immunosorbent Assay (ELISA).This interventional study was carried out atDepartment of Physiology, Faculty of Medicine, King Khalid University Hospital, King Saud University, Riyadh, Saudi Arabia, from October 2018 to February 2019. Results: Mean six minutes’ walk distance (6MWD) was 395±68.4 m at 1st visit increased significantly (p=0.001) to 458.8±87.1 mat 15 visit. However, 6MWD values found significantly higher in controls (517.4±84.1 m; 561.7±81.6 m; p=0.013) thanILD patients. Overall change (difference between post and pre exercise) in HRvalue was recorded lower in ILD patients (30-35 bpm) as compared to controls (40-45 bpm). Moreover, ILD patients had overall higher SOBQ score than controls. Pre SET Irisin levelsofILD patients (4.24 ± 1.73 pg/ml) and controls (3.43±1.04pg/ml) werefound unchangedafter SET (4.48±2.02pg/ml, 3.39 ±1.41pg/ml,p=0.677, p=0.093) respectively. However, patients Irisin values were foundhigher as compared to controls before and after SET. Conclusion: Exercise capacity and Dyspneain patients with ILD were improved after 8-week of SET program. No major changes in Irisin levels among patients with ILD and controls were observed. Additional research requires to be carried out on large number of subjects to deterMinutese the advantages of exercise in ILD. doi: https://doi.org/10.12669/pjms.36.5.1795 How to cite this:Alyami RM, Alhwaikan AM, Alharbi AR, AL-Nafisah G.

Background:Interstitial lung disease (ILD) is characterised by exertional dyspnoea, exercise limitation and reduced quality of life. The role of exercise training in this diverse patient group is unclear. The aims of this study were to establish the safety of exercise training in ILD; its effects on exercise capacity, dyspnoea and quality of life; and whether patients with idiopathic pulmonary fibrosis (IPF) had similar responses to those with other types of ILD.Methods:57 subjects with ILD (34 IPF) were randomised to receive 8 weeks of supervised exercise training or weekly telephone support. The 6 min walk distance (6MWD), incremental exercise test, modified Medical Research Council (MRC) dyspnoea score and Chronic Respiratory Disease Questionnaire (CRDQ) were performed at baseline, following intervention and at 6 months.Results:80% of subjects completed the exercise programme and no adverse events were recorded. The 6MWD increased following training (mean difference to control 35 m, 95% CI 6 to 64 m). A significant reduction in MRC score was observed (0.7 points, 95% CI 0.1 to 1.3) along with improvements in dyspnoea (p = 0.04) and fatigue (p<0.01) on the CRDQ. There was no change in peak oxygen uptake; however, exercise training reduced heart rate at maximum isoworkload (p = 0.01). There were no significant differences in response between those with and without IPF. After 6 months there were no differences between the training and control group for any outcome variable.Conclusions:Exercise training improves exercise capacity and symptoms in patients with ILD, but these benefits are not sustained 6 months following intervention.Trial registration number:NCT00168285

Background. Although digital clubbing is a common presentation in patients with interstitial lung disease (ILD), little has been reported regarding its role in assessing patients with ILD. This study evaluated patients with ILD for the presence of clubbing and investigated its association with clinical data. Methods. We evaluated patients with ILD who visited the teaching hospital at which the study was conducted, between October 2014 and January 2015. Clubbing, evaluated using a Vernier caliper for individual patients, was defined as a phalangeal depth ratio > 1. We examined the association of clubbing with clinical data. Results. Of 102 patients with ILD, we identified 17 (16.7%) with clubbing. The partial pressure of oxygen in arterial blood was lower (65.2 ± 5.9 mmHg versus 80.2 ± 3.1 mmHg; p=0.03), serum Krebs von den Lugen-6 (KL-6) levels were higher (1495.0 ± 277.4 U/mL versus 839.1 ± 70.2 U/mL; p=0.001), and the percent predicted diffusing capacity of carbon monoxide was lower (50.0 ± 6.0 versus 73.5 ± 3.1; p=0.002) in these patients with clubbing. Conclusions. Patients with clubbing had lower oxygen levels, higher serum KL-6 levels, and lower pulmonary function than those without clubbing.
