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 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.

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

Objective. Soluble CD206 (sCD206) is considered a macrophage activation marker, and a previous study proved it as a potential biomarker to predict the severity of anti-melanoma differentiation-associated gene 5- (anti-MDA-5-) positive dermatomyositis- (DM-) associated interstitial lung disease (ILD). To investigate the role of sCD206 in various subtypes of DM, we evaluated the serum level of sCD206 in patients with different myositis-specific autoantibodies besides anti-MDA-5 and clarified its clinical significance. Methods. Commercial enzyme-linked immunosorbent assay kits were used to detect serum concentrations of sCD206 in 150 patients with DM and 52 healthy controls (HCs). Correlations between sCD206 levels and clinical features, laboratory examinations, and pulmonary function test parameters were analysed. Results. The median concentrations of serum sCD206 in DM patients were significantly higher than those in HCs ( p < 0.0001 ). Furthermore, median sCD206 levels were elevated in patients with ILD ( p = 0.001 ), especially in those with rapidly progressive ILD (RP-ILD) ( p < 0.0001 ). In addition, sCD206 levels were negatively correlated with the pulmonary function test results, including the percent predicted forced vital capacity ( r = − 0.234 , p = 0.023 ), percent predicted forced expiratory volume in one second ( r = − 0.225 , p = 0.030 ), and percent predicted carbon monoxide diffusion capacity ( r = − 0.261 , p = 0.014 ). Age- and gender-adjusted multivariable analysis showed that sCD206 was an independent prognostic factor for RP-ILD in patients with DM. A longitudinal study showed that sCD206 levels were positively correlated with the physician global assessment visual analog scale scores ( β = 54.201 , p = 0.001 ). Conclusion. Serum sCD206 levels were significantly increased in patients with DM and significantly associated with RP-ILD, suggesting that sCD206 is an important biological predictor of RP-ILD in patients with DM.

Exercise intolerance and impaired quality of life (QoL) are characteristic of lung transplant candidates and recipients. This review investigated the effects of exercise training on exercise capacity, QoL and clinical outcomes in pre- and post-operative lung transplant patients.A systematic literature search of PubMed, Nursing and Allied Health, Cochrane (CENTRAL), Scopus and CINAHL databases was conducted from inception until February, 2020. The inclusion criteria were assessment of the impact of exercise training before or after lung transplantation on exercise capacity, QoL or clinical outcomes.21 studies met the inclusion criteria, comprising 1488 lung transplant candidates and 1108 recipients. Studies consisted of five RCTs, two quasi-experimental and 14 single-arm cohort or pilot studies. Exercise training improved or at least maintained exercise capacity and QoL before and after lung transplantation. The impact on clinical outcomes was less clear but suggested a survival benefit. The quality of evidence ranged from fair to excellent.Exercise training appears to be beneficial for patients before and after lung transplantation; however, the evidence for direct causation is limited by the lack of controlled trials. Well-designed RCTs are needed, as well as further research into the effect of exercise training on important post-transplant clinical outcomes, such as time to discharge, rejection, infection, survival and re-hospitalisation.
