Antifibrotic therapy in idiopathic pulmonary fibrosis candidates for lung transplantation undergoing pulmonary rehabilitation.

OBJECTIVE: To investigate the impact of pulmonary rehabilitation (PR) on functional outcomes and health-related quality of life (HRQoL) in idiopathic pulmonary fibrosis (IPF) patients placed on a lung transplant waitlist and receiving antifibrotic therapy (AFT). METHODS: This was a retrospective observational study of consecutive IPF patients receiving AFT with either pirfenidone or nintedanib (the AFT group) and undergoing PR between January of 2018 and March of 2020. The AFT group and the control group (i.e., IPF patients not receiving AFT) participated in a 12-week PR program consisting of 36 sessions. After having completed the program, the study participants were evaluated for the six-minute walk distance (6MWD) and HRQoL. Pre- and post-PR 6MWD and HRQoL were compared within groups and between groups. RESULTS: There was no significant difference between the AFT and control groups regarding baseline characteristics, including age, airflow limitation, comorbidities, and oxygen requirement. The AFT group had a significant increase in the 6MWD after 12 weeks of PR (effect size, 0.77; p < 0.05), this increase being significant in the between-group comparison as well (effect size, 0.55; p < 0.05). The AFT group showed a significant improvement in the physical component of HRQoL at 12 weeks (effect size, 0.30; p < 0.05). CONCLUSIONS: Among IPF patients undergoing PR, those receiving AFT appear to have greater improvements in the 6MWD and the physical component of HRQoL than do those not receiving AFT.

Ambulatory oxygen therapy in lung transplantation candidates with idiopathic pulmonary fibrosis referred for pulmonary rehabilitation.

OBJECTIVE: To determine independent factors related to the use of oxygen and the oxygen flow rate in idiopathic pulmonary fibrosis (IPF) patients placed on a lung transplant waitlist and undergoing pulmonary rehabilitation (PR). METHODS: This was a retrospective quasi-experimental study presenting functional capacity and health-related quality of life (HRQoL) data from lung transplant candidates with IPF referred for PR and receiving ambulatory oxygen therapy. The patients were divided into three groups on the basis of the oxygen flow rate: 0 L/min (the control group), 1-3 L/min, and 4-5 L/min. Data on functional capacity were collected by means of the six-minute walk test, and data on HRQoL were collected by means of the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36), being collected before and after 36 sessions of PR including aerobic and strength exercises. RESULTS: The six-minute walk distance improved in all three groups (0 L/min: Δ 61 m, p < 0.001; 1-3 L/min: Δ 58 m, p = 0.014; and 4-5 L/min: Δ 35 m, p = 0.031). Regarding HRQoL, SF-36 physical functioning domain scores improved in all three groups, and the groups of patients receiving ambulatory oxygen therapy had improvements in other SF-36 domains, including role-physical (1-3 L/min: p = 0.016; 4-5 L/min: p = 0.040), general health (4-5 L/min: p = 0.013), social functioning (1-3 L/min: p = 0.044), and mental health (1-3 L/min: p = 0.046). CONCLUSIONS: The use of ambulatory oxygen therapy during PR in lung transplant candidates with IPF and significant hypoxemia on exertion appears to improve functional capacity and HRQoL.

RESUMO Objetivo: Investigar o impacto da reabilitação pulmonar (RP) em desfechos funcionais e na qualidade de vida relacionada à saúde (QVRS) em pacientes com fibrose pulmonar idiopática (FPI) em lista de espera para transplante de pulmão e em tratamento com antifibróticos (AF). Métodos: Estudo observacional retrospectivo com pacientes consecutivos com FPI em tratamento com pirfenidona ou nintedanibe (grupo AF) submetidos a RP entre janeiro de 2018 e março de 2020. O grupo AF e o grupo controle (pacientes com FPI que não estavam em tratamento com AF) participaram de um programa de RP com 36 sessões ao longo de 12 semanas. Após o término do programa, os participantes foram avaliados quanto à distância percorrida no teste de caminhada de seis minutos (DTC6) e à QVRS. A DTC6 e a QVRS pré e pós-RP foram comparadas intra e intergrupos. Resultados: Não houve diferença significativa entre os grupos AF e controle quanto às características basais, incluindo idade, limitação do fluxo aéreo, comorbidades e necessidade de oxigênio. O grupo AF apresentou um aumento significativo da DTC6 após 12 semanas de RP (tamanho do efeito: 0,77; p < 0,05); esse aumento também foi significativo na comparação intergrupos (tamanho do efeito: 0,55; p < 0,05). O grupo AF apresentou melhora significativa no componente físico da QVRS após 12 semanas (tamanho do efeito: 0,30; p < 0,05). Conclusões: Em pacientes com FPI submetidos a RP, a melhora na DTC6 e no componente físico da QVRS parece ser maior naqueles que estejam recebendo tratamento com AF do que naqueles que não o estejam.

A Telerehabilitation Program for Maintaining Functional Capacity in Patients With Chronic Lung Diseases During a Period of COVID-19 Social Isolation: Quasi-Experimental Retrospective Study.

BACKGROUND: Pulmonary diseases represent a great cause of disability and mortality in the world, and given the progression of these pathologies, pulmonary rehabilitation programs have proven to be effective for people with chronic respiratory diseases. During the COVID-19 pandemic, telerehabilitation has become an alternative for patients with such diseases. OBJECTIVE: The aim of this study was to compare the outcomes (ie, functional capacity and quality of life) of telerehabilitation to those of usual care among patients who previously participated in face-to-face pulmonary rehabilitation programs. METHODS: We conducted a quasi-experimental retrospective study from April 2020 to August 2021. A total of 32 patients with chronic lung diseases were included and divided into the control and intervention groups. The intervention group performed telerehabilitation synchronously twice per week and was supervised by a physical therapist during breathing, strengthening, and aerobic exercises. Changes in the degree of dyspnea and leg discomfort were assessed based on changes in Borg scale scores. The control group did not perform any activities during the period of social isolation. Functional capacity was assessed with the 6-minute walk test, and quality of life was assessed with the Medical Outcomes Study 36-item Short Form Health Survey. RESULTS: The telerehabilitation group's mean 6-minute walk distance decreased by 39 m, while that of the control group decreased by 120 m. There was a difference of 81 m between the groups' mean 6-minute walk distances (P=.02). In relation to the quality of life, telerehabilitation was shown to improve the following two domains: social functioning and mental health. CONCLUSIONS: Telerehabilitation programs for patients with chronic lung diseases can ease the deleterious effects of disease progression, be used to maintain functional capacity, and improve aspects of quality of life.

Validity and reliability of the Glittre-ADL test in individuals with idiopathic pulmonary fibrosis.

BACKGROUND: Patients with idiopathic pulmonary fibrosis (IPF) often present with dyspnea, fatigue, and desaturation. These symptoms can be highly limiting, as they lead to a decrease in performing activities of daily living (ADL). Therefore, it is essential to evaluate the degree of functional limitation of these individuals. OBJECTIVE: The present study aimed to evaluate the validity and reliability of the Glittre-ADL test (TGlittre) and its association with self-reported limitation in ADL and health-related quality of life (HRQoL) in patients with IPF. METHODS: Twenty-seven individuals with IPF (60.5 ± 10.6 years), with forced vital capacity 2.26 ± 1.03 L (51.09 ± 20.62% of predicted) were assessed for the time spent in TGlittre, 6-minute walking distance (6MWD), limitation in ADL and HRQoL. RESULTS: TGlittre was reliable (intraclass correlation coefficient3,1 = 0.96; P < .001); however, a learning effect of 10.6% was observed between the first and second execution of TGlittre. The time spent in TGlittre correlated with 6MWD, limitation in ADL, and disease-specific HRQoL (P < .05). CONCLUSION: TGlittre is valid and reliable for assessing functional capacity in patients with IPF. Still, it presents a learning effect and should be performed twice when assessing functional capacity in clinical practice.

Pulmonary rehabilitation improves survival in patients with idiopathic pulmonary fibrosis undergoing lung transplantation.

This study was conducted to evaluate whether a pulmonary rehabilitation program (PRP) is independently associated with survival in patients with idiopathic pulmonary fibrosis (IPF) undergoing lung transplant (LTx). This quasi-experimental study included 89 patients who underwent LTx due to IPF. Thirty-two completed all 36 sessions in a PRP while on the waiting list for LTx (PRP group), and 53 completed fewer than 36 sessions (controls). Survival after LTx was the main outcome; invasive mechanical ventilation (IMV), length of stay (LOS) in intensive care unit (ICU) and in hospital were secondary outcomes. Kaplan-Meier curves and Cox regression models were used in survival analyses. Cox regression models showed that the PRP group had a reduced 54.0% (hazard ratio = 0.464, 95% confidence interval 0.222-0.970, p = 0.041) risk of death. A lower number of patients in the PRP group required IMV for more than 24 hours after LTx (9.0% vs. 41.6% p = 0.001). This group also spent a mean of 5 days less in the ICU (p = 0.004) and 5 days less in hospital (p = 0.046). In conclusion, PRP PRP completion halved the risk of cumulative mortality in patients with IPF undergoing unilateral LTx.

Pulmonary Rehabilitation in Patients With Advanced Idiopathic Pulmonary Fibrosis Referred for Lung Transplantation.

PURPOSE: Currently, pulmonary rehabilitation (PR) has a weak recommendation for idiopathic pulmonary fibrosis (IPF) and is often recommended for mild to moderate disease. We aimed to investigate the completion rate of PR in patients with advanced IPF, to analyze whether the severity of disease influences PR response and whether there is any difference between subjects who are able or not able to successfully complete the program. METHODS: Patients with IPF referred to lung transplantation (n = 48) were enrolled in an outpatient PR program including 3 times/wk supervised exercise training during 12 wk. A short-form 36-item health-related quality-of-life (HRQL) questionnaire and 6-min walk test distance (6MWD) were evaluated before and after PR. RESULTS: We found that 64.5% of patients successfully completed PR (31/48). Baseline forced vital capacity (FVC) and lung diffusion capacity for carbon monoxide (DLCO) were 49% ± 13% and 46% ± 17% of predicted, respectively. There was no difference comparing those who did and did not complete PR. In the former group, 6MWD (58 ± 63 m) and several domains of the HRQL questionnaire improved significantly. No significant association was found between markers of disease severity (FVC, DLCO, and dyspnea) and improvement in clinical outcomes. CONCLUSIONS: Two-thirds of our sample with advanced IPF referred to lung transplant successfully attended PR and improved exercise capacity and HRQL, without association with markers of disease severity. No difference was found at baseline compared with subjects who were not able to complete the program.

Impact of pulmonary rehabilitation on quality of life and functional capacity in patients on waiting lists for lung transplantation.

OBJECTIVE: To investigate the impact of a pulmonary rehabilitation program on the functional capacity and on the quality of life of patients on waiting lists for lung transplantation. METHODS: Patients on lung transplant waiting lists were referred to a pulmonary rehabilitation program consisting of 36 sessions. Before and after the program, participating patients were evaluated with the six-minute walk test and the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36). The pulmonary rehabilitation program involved muscle strengthening exercises, aerobic training, clinical evaluation, psychiatric evaluation, nutritional counseling, social assistance, and educational lectures. RESULTS: Of the 112 patients initially referred to the program, 58 completed it. The mean age of the participants was 46 ± 14 years, and females accounted for 52%. Of those 58 patients, 37 (47%) had pulmonary fibrosis, 13 (22%) had pulmonary emphysema, and 18 (31%) had other types of advanced lung disease. The six-minute walk distance was significantly greater after the program than before (439 ± 114 m vs. 367 ± 136 m, p = 0.001), the mean increase being 72 m. There were significant point increases in the scores on the following SF-36 domains: physical functioning, up 22 (p = 0.001), role-physical, up 10 (p = 0.045); vitality, up 10 (p < 0.001); social functioning, up 15 (p = 0.001); and mental health, up 8 (p = 0.001). CONCLUSIONS: Pulmonary rehabilitation had a positive impact on exercise capacity and quality of life in patients on lung transplant waiting lists.

Applicability of the London Chest Activity of Daily Living scale in patients on the waiting list for lung transplantation.

OBJECTIVE: To evaluate the applicability of the London Chest Activity of Daily Living (LCADL) scale in patients on the waiting list for lung transplantation. METHODS: This was a cross-sectional study, conducted between May and September of 2010, involving 26 male and female patients on the waiting list for lung transplantation and treated at the Pulmonary Rehabilitation Program in the Complexo Hospitalar Santa Casa de Misericórdia de Porto Alegre, located in the city of Porto Alegre, Brazil. We evaluated the patients using the six-minute walk test (6MWT) and pulmonary function tests. We also obtained the LCADL scores, as well as the modified Borg scale scores for sensation of dyspnea and leg fatigue. Cronbach's alpha coefficient was used to determine the internal consistency of the LCADL scale. Linear regression analysis was used in order to identify associations between the total LCADL score (expressed as a percentage) and the variables studied. RESULTS: According to the LCADL scale results, 69% of the patients reported that the performance of their activities of daily living was significantly impaired by their dyspnea. The internal consistency of the LCADL scale was 0.89. After adjusting for age and FEV1, we found that the total LCADL scale score showed statistically significant negative associations with the six-minute walk distance (ß = -0.087; p < 0.001) and the six-minute walk work (ß = -0.285; p < 0.001). CONCLUSIONS: Our findings suggest that the LCADL scale is a useful tool for assessing patients on the waiting list for lung transplantation.
