RESUMEN

Introduction: This study aimed to investigate whether inspiratory muscle strength was associated with bacterial colonization and other clinical outcomes and whether bacterial colonization was associated with clinical outcomes in patients with non-cystic fibrosis bronchiectasis (NCFB). Materials and Methods: Eighty-six patients were enrolled in a cross-sectional study. Patients were divided into two groups according to the presence of inspiratory muscle weakness and bacterial colonization. Parameters were compared between groups. Result: Bronchiectasis etiologies were post-infectious, Kartagener's syndrome, and primary ciliary dyskinesia. The median value of MIP was -68, and MEP was 89 cm H2O in all patients. Although the ratio of bacterial colonization was similar to patients without inspiratory muscle weakness, the inspiratory muscle weakness group had a higher number of females, lower FEV1, FVC, ISWT, CRQ, higher MRC, E-FACED, SGRQ, number of hospitalization (p<0.05). When colonized and non-colonized patients were compared, MIP, and MEP were similar in spite of adjusted BMI, age, and sex. FEV1, FVC, ISWT, and ESWT were lower, and E-FACED scores (p<0.05) were higher in colonized patients. Conclusions: Although inspiratory muscle strength was not associated with bacterial colonization in NCFB patients, it is an important factor that could be linked to disease severity, pulmonary functions, quality of life, and exercise capacity. Bacterial colonization was also associated with severe disease, deteriorated pulmonary functions, and exercise capacity.

RESUMEN

Introduction: Post-illness pulmonary rehabilitation indications of Coronavirus disease-2019 (COVID-19) may include fatigue, respiratory restriction, exercise limitation, muscle weakness, deterioration in body composition, quality of life, and psychological status. Since tele-pulmonary rehabilitation (tele-PR) is the prominent approach in the current situation and questions such as who, how, and when are still unclear, in this study we aimed to investigate the efficacy of tele-PR as a hybrid model with face-to-face in post-COVID-19 patients. Materials and Methods: Thirty one patients who had completed viral infection treatment with the diagnosis of COVID-19 but still had persistent symptoms were enrolled in an eight-week synchronized video-conference mediated telePR program in a hybrid format, with the initial and final assessments and the first two sessions conducted in person. Before and after the tele-PR, pulmonary functions, exercise capacity, respiratory and peripheral muscle strength, body composition, quality of life, and psychological states were evaluated. Result: After the tele-PR program; a statistically significant improvement was observed in dyspnea sensation evaluated with modified Medical Research Council (mMRC) and BORG levels, body mass index (BMI), incremental shuttle walk test (ISWT), endurance shuttle walk test (ESWT), handgrip test, deltoid, and quadriceps 1-repetition maximum (1RM) results, maximal inspiratory and expiratory pressure (MIP, MEP), peripheral muscle strengths, fatigue severity scale and Nottingham extended activities of daily living scale (NEADLS). Conclusions: In this study, it has been shown that the hybrid model of tele-PR enables a comprehensive evaluation as well as the effective and safe applicability of a multidisciplinary and remotely directed program even in high workloads for post-COVID-19 patients.

RESUMEN

Pleuroparenchymal fibroelastosis (PPFE) is an uncommon disease of which diagnosis should be established multidisciplinary fashion and has no effective medical therapy. Pulmonary rehabilitation (PR) can be applied, but lung transplantation is the only therapeutic option. There have been few reported cases or studies showing the efficacy of PR in patients with PPFE in the literature. We present our multidisciplinary PR programme including confirmation of the diagnosis and a structured follow-up programme in two PPFE patients. In both cases, after multidisciplinary PR the diagnoses were confirmed and body composition, quality of life, exercise capacity and psychological status improved and some improvements preserved for 6-12 months. They underwent lung transplantation about 2 years after PR. Patients with PPFE should be directed and encouraged to participate in comprehensive multidisciplinary PR programmes. Long-term structured follow-up programmes could preserve the improvements, increase adherence and save time while waiting on the transplant list.

RESUMEN

INTRODUCTION: Pulmonary rehabilitation (PR) is an effective approach for patients with chronic pulmonary disease, and it is also recommended for patients with bronchiectasis. The aims of the current study were to evaluate the efficacy of a multidisciplinary PR program and identify factors associated with improvement in patients with bronchiectasis. Material and ethods: We obtained data from patients with bronchiectasis who completed our PR program which consisted of education and training regarding bronchial hygiene. Pulmonary function test results, body composition, exercise capacity, quality of life, and psychological status were assessed before and after the PR program. RESULTS: We enrolled 130 patients in this retrospective study. Most patients had a history of pneumonia. The Medical Research Council (MRC) dyspnea scale, incremental shuttle walking test (ISWT), endurance shuttle walking test (ESWT), St. George's Respiratory Questionnaire (SGRQ), Chronic Respiratory Questionnaire (CRQ), and Hospital Anxiety and Depression (HAD) scores statistically improved after the PR program (all p < 0.001). Improvements were similar regardless of sex, etiology, smoking sta-tus, or number of hospitalizations. Age was negatively correlated with ΔSGRQ (p = 0.024, r = -0.203). Baseline forced expiratory volume in 1s (FEV1) was positively correlated with ΔCRQ (p = 0.015, r = 0.213) and negatively correlated with Δanxiety (p = 0.014, r = -0.215). Baseline MRC was negatively correlated with ΔMRC (p < 0.001, r = -0.563) and ΔSGRQ (p < 0.001, r = -0.308). Baseline ISWT was negatively correlated with ΔISWT (p = 0.043, r = -0.176) and Δanxiety (p = 0.007, r = -0.237). Baseline SGRQ was negatively correlated with ΔMRC (p = 0.003, r = -0.267) and ΔSGRQ (p < 0.001, r = -0.648). CONCLUSIONS: Our PR program is efficacious for patients with bronchiectasis regardless of sex, etiologic cause of bronchiectasis, concomitant chronic obstructive pulmonary disease, smoking status, and/or number of hospitalizations. Improvement varied among patients which highlights the need for more studies to determine which patients will benefit most from the program.

RESUMEN

Background: Pulmonary rehabilitation (PR) is an effective treatment in patients with chronic obstructive pulmonary disease (COPD) but still underutilized. The aim of this study was to compare unsupervised home PR with supervised outpatient PR in terms of various clinical variables in COPD patients.Methods: We conducted retrospective study consisting of 247 patients with COPD who were categorized into three group. 127 patients underwent unsupervised home PR, of whom 60 (47%) completed program (finishers), 67(53%) were lost to follow-up (non-finishers), 120 completed supervised outpatient PR. We compared baseline, post-treatment changes in demographic, clinical variables.Results: Sex, age were statistically similar between groups. Finishers of home PR had higher exercise capacity (p = 0.003), quality of life (p = 0.045), FEV1 (p = 0.001), lower pack-year smoking (p < 0.001) than outpatient PR.After home PR, exercise capacity (p < 0.05), quality of life (p < 0.001), dyspnea(p < 0.05), anxiety (p < 0.001), depression (p < 0.001) were improved except endurance shutte test. Improvements in exercise capacity (p < 0.05), quality of life (p < 0.001), dyspnea (p = 0.023), anxiety (p < 0.001), depression (p = 0.001) scores were different between completed PR programs, in favor of supervised outpatient PR. Non-finishers of home PR had more pack-year smoking than finishers of home PR (p = 0.039); other baseline parameters were similar.Conclusion: Unsupervised home PR was effective in terms of improving exercise capacity, quality of life, dyspnea, psychological status, but less than supervised outpatient programs.

RESUMEN

INTRODUCTION: Pulmonary rehabilitation (PR) is well-proven approach on improving dyspnea, exercise intolerance which are two components of BODE index. But, PR is known to have minimal effect on pulmonary function which is another component of BODE index. There are few studies evaluating PR efficacy by using i-BODE index. Our aim was to evaluate efficacy of PR in patients with chronic obstructive pulmonary disease (COPD) with i-BODE index and to investigate changes in i-BODE index according to GOLD 2011 combined assessment. MATERIALS AND METHODS: A total of 228 stable COPD patients who completed a comprehensive 8 week duration PR program were enrolled into this retrospective study. RESULT: The patients were with mean age of 63.3 ± 8.6 years and mean FEV1% was 38.6 ± 16.2%. According to combined assessment of COPD, 23 patients were group A, 30 patients were B, 31 patients were C and 144 patients were D. Baseline i-BODE scores correlated with body compositions, pulmonary function, dyspnea, exercise capacity, psychological status, quality of life, and age. i-BODE index score decreased from 4.7 ± 2.2 to 3.5 ± 1.8 after PR (p<0.001), improved by 26%. Significant improvements were found in dyspnea, quality of life and i-BODE index in more symptomatic patients (group B and D). CONCLUSIONS: This study highlights that changes in i-BODE scores after PR significantly correlated with improvements in dyspnea, exercise capacity and quality of life. i-BODE score could be a better predictor of efficacy of PR than some individual variables such as BMI or FEV1. Significant improvements in dyspnea sensation, quality of life and i-BODE index could be seen symptomatic patients in after PR.

RESUMEN

PURPOSE: Pulmonary rehabilitation (PR) is advocated in the pre- and post-lung transplantation (LTx) periods. However, there is limited literature on the benefit of PR post-LTx. The aim of this study was to investigate the efficacy of an outpatient, multidisciplinary, comprehensive PR program in bilateral LTx recipients in the early period after LTx. METHOD: Twenty-three LTx recipients were referred to the PR center. Change in incremental and endurance shuttle walk tests, hand and quadriceps strength, respiratory muscle strength (maximum inspiratory/expiratory pressure), dyspnea (Medical Research Council score), quality of life (St George's Respiratory Questionnaire, Chronic Respiratory Questionnaire), and psychological status (Hospital Anxiety Depression Scale) were compared pre- and post-PR. RESULTS: Seventeen of 23 (74%) recipients completed PR, comprising 15 male and 2 female patients whose median age was 51 yr. The initiation of the program was 75 ± 15 d after LTx. The incremental shuttle walk test distance was predicted as 23% before PR and it increased to 36% after PR (P < .001); the endurance shuttle walk test distance also increased (P < .01). Significant improvement was seen in upper and lower extremity strength, and St George's Respiratory Questionnaire and Chronic Respiratory Questionnaire scores and Hospital Anxiety Depression Scale scores reflected less anxiety and depressive symptoms. Furthermore, body mass and fat-free mass indices, maximum inspiratory pressure, and maximum expiratory pressure improved significantly. There was no significant change in forced expiratory volume in the first second of expiration, forced vital capacity, or Medical Research Council scores. CONCLUSION: This study demonstrated that patients who attended PR within 3 mo of bilateral LTx showed improvements in exercise capacity, respiratory muscle strength, quality of life, body composition, and psychological status.

RESUMEN

INTRODUCTION: In chronic obstructive pulmonary disease (COPD), skeletal muscle weakness is characterized by reduced muscle strength, reduced muscle endurance and the presence of muscle fatigue especially in lower limbs. There has been little research into the upper limb skeletal muscles. OBJECTIVES: In this study, we aimed to investigate the relation of upper limb muscle strength with pulmonary function, exercise capacity, quality of life (QoL) and dyspnea sensation. METHODS: Eigthy-eight patients (89.8% male; age: 64.2 ± 8.7 years) with COPD (FEV1 = 34.2% ± 15.2%) were evaluated. Tests included hand grip strength and actual 1-repetition maximum (1RM) test for upper limb strength. Dyspnea sensation was assessed with medical research council (MRC) scale. St. George Respiratory Questionary (SGRQ) was used to evaluate patients health related QoL. Exercise capacity was evaluated with incremental shuttle walk test and endurance shuttle walk test. RESULTS: Upper limb muscle strength correlated with exercise capacity but no correlations were found with pulmonary functions.There were negative correlations with all the domains of SGRQ both actual 1RM and handgrip strength. MRC scores revealed a negative correlation with upper limb muscle strength. CONCLUSION: In our study, we showed that upper limb muscle strength correlated with exercise capacity, QoL, dyspnea sensation. Identifying patients who have greater reductions in strength will allow early interventions with a multidisciplinary manner.

RESUMEN

INTRODUCTION: COPD is among the most common causes for secondary pulmonary hypertension (PH). Pulmonary rehabilitation (PR) is recommended in the standard treatment of COPD. In this study, efficiency of multidisciplinary PR in COPD patients with PH was examined. PATIENTS AND METHODS: 88 patients stable COPD patients who applied to our center between 2008-2013 were enrolled. Un-likely PH patients were grouped as Group 1 while possible and likely PH cases were accepted as Group 2. There were no other cause for PH. All the patients received patient-specific, multidisciplinary 8-week PR. Dyspnea perception was assessed via MRC dyspnea scale, health-related quality of life with S. George life quality questionnaire, exercise capacity via incremental shuttle walking test and endurance shuttle walking test and body composition via bioelectrical impedance test before and after PR program. RESULTS: In all the patients there were significant improvements in body composition (BMI p= 0.013), quality of life (SGRQ semp., activity, total p< 0.001), dyspnea perception (MRC p< 0.001) and exercise capacity (ISWTT, ESWT, VO2 peak p< 0.001) after PR program. Improvements in Group 2 were observed to be significantly greater. CONCLUSION: PR is an effective and safe option in COPD patients with PH. These patients should be directed to PH programs for supervised exercise training and chronic disease management and patient-specific PR programs should be established.

RESUMEN

AIM: The purpose of this study was to investigate whether adding neuromuscular electrical stimulation (NMES) to a comprehensive pulmonary rehabilitation (cPR) program would have additive effects on clinical-functional outcomes. METHODS: Twenty-seven chronic obstructive pulmonary disease patients participating in a 10-week cPR program were randomly allocated to NMES + cPR (n = 13) or Sham + cPR (n = 14) groups. Quadriceps strength, exercise capacity, symptoms, mood, activities of daily living and quality of life were evaluated pre- and post-interventions. RESULTS: There were no significant differences in any of the physiological and subjective improvements induced by NMES + cPR versus Sham + cPR (p > 0.05). In fact, the NMES + cPR group showed lower increases in incremental shuttle walk test (ISWT) distance (38.4 vs 69.2 m, respectively) and %ISWT distance (5.1 vs 9%, respectively) compared with the Sham + cPR group (p < 0.05). CONCLUSION: The increase in exercise capacity is less important when NMES is used as an adjunct to the cPR.

RESUMEN

AIM: We evaluated the relationship between chronic obstructive pulmonary disease (COPD) assessment test (CAT) and improvements after pulmonary rehabilitation (PR) and PR efficiency in COPD patients. METHODS & RESULTS: Forty COPD patients completed PR. After PR, mean change in CAT score was found to be 13 (p < 0.001), Medical Research Council (MRC), St George's Respiratory Questionnaire (SRGQ) and London Chest Activity Daily Living (LCADL) scores decreased, while Endurance Shuttle Walking Test (ESWT) time and Incremental Shuttle Walking Test (ISWT) distance increased significantly. Baseline CAT scores correlated with MRC, SRGQtotal, %FVC, ISWT, ESWT, LCADL. Change in CAT was significantly correlated with changes in MRC, SGRQtotal, LCADL-leisure scores, and ESWT. CONCLUSION: CAT score shows moderate degree correlation with some measures of outcome of PR and response to PR efficacy.

RESUMEN

INTRODUCTION: In severely disabled patients who are not capable of following formal pulmonary rehabilitation (PR) and/or tolerating higher training intensities, neuromuscular electrical stimulation (NMES) has been successfully utilized as a localized training method. MATERIALS AND METHODS: In this non-randomized controlled observational study 50 patients with severe chronic obstructive pulmonary disease (COPD), who were allocated into two groups. Endurance training group (ET) (n= 27) and NMES group (n= 23). To compare the effects of NMES and ET on health-related quality of life (HRQOL), exercise capacity, muscle strength, dyspnea, psychological status, and body composition in patients with severe COPD. Before and after PR program, the study parameters were assessed using the Medical Research Council (MRC) scale, incremental and endurance shuttle walking tests (ISWT, ESWT), manual muscle testing (MMT), the St. George's Respiratory Questionnaire (SGRQ), bioelectrical impedance analysis, and the Hospital Anxiety and Depression Scale (HADS). RESULTS: After the PR program, walking distance and endurance time significantly increased in both groups (p< 0.001 for each), whereas the MRC scores of both groups significantly decreased (p< 0.001 for each). In the ET group, significant decreases were noted in all domains of SGRQ and HADS. In the NMES group, significant improvements were observed in the HADS scores and in all SGRQ domain except symptom domain. No significant differences were observed between the NMES and ET groups regarding the changes from baseline to after PR program in walking distance (p= 0.140), endurance time (p= 0.376), the MRC (p= 0.540), HRQOL (p> 0.05) and HADS (p> 0.05) scores, body-mass index (BMI) (p= 0.49), fat-free mass (FFM) (p= 0.50) and fat-free mass index (FFMI) (p= 0.94). CONCLUSION: NMES can be used as an effective treatment strategy in PR programs for peripheral muscle training in patients with severe COPD.

RESUMEN

BACKGROUND AND OBJECTIVE: Chronic obstructive pulmonary disease (COPD) is considered a worldwide major public health problem. Weight loss, muscle and fat mass depletion are common nutritional problems in COPD patients and are determinant factors in pulmonary function, health status, disability and mortality. We aimed to assess the relationships between nutritional status and perception of dyspnoea, pulmonary function tests (PFT), exercise capacity and health-related quality of life (HRQoL) using the subjective global assessment (SGA) in COPD patients who were referred for pulmonary rehabilitation programme. METHODS: A total of 163 patients with stable COPD who are candidates for outpatient pulmonary rehabilitation programme were included in this study. Nutritional status for all patients was assessed by SGA. Association of SGA scores (A, B and C) and anthropometric measurements, PFT, dyspnoea scales (Medical Research Council and resting BORG scale), HRQoL (St. George Respiratory Questionnaire and Chronic Respiratory Diseases Questionnaire) and exercise testing (shuttle walking test) were studied for statistical significance. RESULTS: Based on SGA, 9.2% of patients were severely malnourished (SGA-C). There were significant decreases in forced expiratory volume in the first second (FEV1 ) (P = 0.009), Medical Research Council scales (P < 0.001) and exercise capacity (incremental shuttle walking test (P = 0.001) and endurance shuttle walking test (P = 0.009)) in SGA-C. Deterioration in anthropometric measurements and HRQoL measures were observed in malnourished patients. CONCLUSIONS: Identifying the nutritional status and determining any requirement for nutritional supplement is an important component of comprehensive pulmonary rehabilitation programme. SGA is an easy and practical method to assess nutritional status in pulmonary rehabilitation candidate patients with stable COPD.

RESUMEN

INTRODUCTION: Interstitial lung diseases are characterised by dyspnea on exertion, low quality of life, cough and exercise intolerance. The aim of this study was to evaluate the effects of comprehensive pulmonary rehabilitation in patients with interstitial lung disease. MATERIALS AND METHODS: Data from patients who were referred to pulmonary rehabilitation with the diagnosis of interstitial lung diseases were included to this study. Ten patients with interstitial lung disease participated to our outpatient, 8 weeks, comprehensive pulmonary rehabilitation programme. Dyspnea was assessed with the Medical Research Council (MRC) scale; health related quality of life was assessed with the St.George's Respiratory Questionnaire (SGRQ). Exercise capacity was measured using the incremental shuttle walk test (ISWT) and endurance shuttle walk test (ESWT); anxiety and depression were assessed with the hospital anxiety depression scale (HADS). All parameters were recorded before and after pulmonary rehabilitation programme. RESULTS: Dyspnea sensation, anxiety and depression scores decreased after pulmonary rehabilitation (p: 0.023, p: 0.026, p: 0.039 respectively). Also impact domains of SGRQ significantly reduced (Z= 1.988; p= 0.047).The difference between median values of ISWT results before and after pulmonary rehabilitation was 60 meters. Although it was not statistically significant (Z= 1.863; p= 0.063), the level of increment was higher than the minimaly important clinical differance for ISWT. CONCLUSION: Our results showed that comprehensive pulmonary rehabilitation programmes were benefical for patients with interstitial lung diseases and it should be regarded as a standard care in this population from the early stages.

RESUMEN

BACKGROUND: The aim was to evaluate the outcomes of a comprehensive pulmonary rehabilitation (PR) in chronic obstructive pulmonary disease (COPD) and to establish whether in early disease stage PR is as effective as in late stages of disease. METHODS: A total of 55 stable COPD patients, 28 with early and 27 with late disease stages, were assessed. Patients underwent a comprehensive out-patient PR program for 8 weeks. To eluciate the effects of PR and compare the level of improvement; lung function, dyspnea sensation [Medical Research Council (MRC)], body composition [body mass index (BMI), fat free mass (FFM), fat free mass index (FFMI)], exercise capacity [incremental shuttle walking test, endurance shuttle walking test], health related quality of life (HRQoL) with St. George Respiratory Disease Questionnaire, psycohological status (Hospital anxiety-depression (HAD) scale) were evaluated before and after PR. RESULTS: At the end of PR in the early disease stage group, the improvement in forced vital capacity (FVC) reached a statistically significant level (P < 0.05). In both disease stages, there were no significant differences in BMI, FFM, and FFMI. The decrease in exertional dyspnea for the two groups evaluated with the modified BORG scale were not found statistically significant, though the dyspnea scores evaluated with MRC showed significant improvements (P < 0.001). HRQoL and exercise capacity were significantly improved for the two groups (P < 0.001). Psychological status evaluated with the HAD scale improved after PR (P < 0.001) both in early and late stages. Gainings in the study parameters did not differ in the early and the late disease stages. CONCLUSIONS: These results showed that patients with COPD had benefited from a comprehensive PR program in an out-patient setting regardless of disease severity. Even patients with earlier stage of disease should be referred and encouraged to participate in a PR program.
