Abstract
OBJECTIVE To evaluate and compare performance in the modified shuttle walk test (MSWT) with cardiorespiratory parameters and respiratory muscle strength in children with cystic fibrosis (CF) and healthy controls. METHODS A cross-sectional study with children divided into the CF group (CFG) and healthy control group (HCG). Two MSWTs were performed and the data from the test with the longest distance walked and its cardiorespiratory parameters (blood pressure, respiratory rate, heart rate (HR), oxygen saturation, and dyspnea sensation) were considered, the last three every 4 levels. Respiratory muscle strength was evaluated using a manometer. The Wilcoxon test was used to compare the parameters before and after the MSWT, and the Mann-Whitney and independent t-tests were applied to compare the data between the groups. The distance walked and its association with the variation in cardiorespiratory parameters and respiratory muscle strength were analyzed by Spearman's correlation. RESULTS Sixty-two children (31 in each group) participated, with an average age of 10.2 (2.1) years. Children with CF had poorer performance in the average distance walked (CFG 716.7 (274.3)) when compared to the HCG (948.0 (202.8)). Both groups exhibited an increase in all the cardiorespiratory parameters at the end of the test, but the CFG displayed less variation in some parameters. Children with CF presented a positive correlation between distance walked and respiratory muscle strength, HR variation, and systolic blood pressure. CONCLUSIONS There was no difference in respiratory muscle strength between the groups. In the CFG, the greater the respiratory muscle strength, the better the performance in the MSWT. The CFG exhibited less variation in cardiorespiratory parameters than the HCG.

Effects of Elexacaftor/Tezacaftor/Ivacaftor on Cardiorespiratory Polygraphy Parameters and Respiratory Muscle Strength in Cystic Fibrosis Patients with Severe Lung Disease. Genes (Basel) 2023; 14:449. [PMID: 36833376 PMCID: PMC9956139 DOI: 10.3390/genes14020449] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 01/17/2023] [Accepted: 02/06/2023] [Indexed: 02/12/2023] Open
Abstract
BACKGROUND Cystic fibrosis transmembrane conductance regulator (CFTR) modulators represent targeted therapies directly acting on the CFTR channel. The triple therapy Elexacaftor/Tezacaftor/Ivacaftor (ELX/TEZ/IVA) has been demonstrated to improve lung function and quality of life in cystic fibrosis (CF) patients. However, the effects of ELX/TEZ/IVA on sleep-disordered breathing (SDB) and respiratory muscle strength are poorly studied. The aim of this study was to assess the effects of ELX/TEZ/IVA in patients with CF and severe lung disease on cardiorespiratory polygraphy parameters, maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP) measures. METHODS patients with CF aged ≥ 12 who started treatment in a compassionate use program were retrospectively studied through the evaluation of nocturnal cardiorespiratory polygraphy parameters, MIP and MEP; and six-minute walk test (6MWT) at baseline and at months 3, 6, and 12 of treatment. RESULTS Nine patients (mean age 30.3 ± 6.5 years) with severe CF (mean baseline ppFEV1 34.6 ± 5.1%) were evaluated. A significant improvement in nocturnal oxygenation measured by mean SpO2 (92.4 vs. 96.4%, p < 0.05), time spent with SpO2 ≤ 90% (-12.6, -14.6, -15.2 min from baseline at months 3, 6, and 12, respectively, p < 0.05), and respiratory rate (RR) was shown, at month 12 and across the time points compared with baseline, as well as in respiratory muscle strength, although only the change in MEP was significant. CONCLUSIONS We provide further evidence on the efficacy of the CFTR modulators ELX/TEZ/IVA, adding information about their effect on the respiratory muscles' performance and cardiorespiratory polygraphy parameters in CF patients with severe lung disease.

Measurement properties of the one-minute sit-to-stand test in children and adolescents with cystic fibrosis: A multicenter randomized cross-over trial. PLoS One 2021; 16:e0246781.

Abstract
Background Functional exercise capacity assessment is recommended in children with cystic fibrosis (CF). The six-minute walk test (6MWT) is a valid evaluation of exercise capacity but can be technically complex. Inversely, the sit-to-stand test (STST) is a simple method to evaluate exercise capacity, and is validated in healthy children and adults with CF. This study aimed to evaluate STST measurement properties in children and adolescents with CF. Methods In this multicenter study, children with CF (6 to 18 years) performed two iterations of both the STST and the 6MWT in a randomized order. Criterion validity was determined by assessing correlations between STST repetitions and 6MWT distance (6MWD). Intra-rater reliability, test-retest repeatability, mean bias and limits of agreement were also assessed. Relationships with other outcomes (i.e. respiratory and quadriceps muscle strength) and cardio-respiratory responses were analysed for both tests. Results Thirty-six children with CF were included (mean age 12.0 ±3.5 years and FEV1 95.8 ±25.0%). On average, 39.6 ±10.5 repetitions were performed during the STST and mean 6MWD was 596.0 ±102.6 meters. STST number of repetitions was significantly correlated with 6MWD (r = 0.48; p<0.01). Both tests had very good intra-rater reliability (ICCSTST = 0.91 (95%CI 0.76–0.96) and ICC6MWT = 0.94 (95%CI 0.85–0.97)), and a significant test-retest learning effect. The number of STST repetitions was not correlated with quadriceps or respiratory muscle strength test, and the STST induced fewer cardio-respiratory responses than the 6MWT. Conclusions The STST is an easy-to-use functional test with moderate criterion validity when compared to the 6MWT in children with CF, probably because both tests measure different components of functional exercise capacity. The STST is useful when the 6MWT is unfeasible, however further investigations are required to explore the clinical implications of STST results in children with CF. Clinical trial registration NCT03069625.

Abstract
Accurate testing of muscle function is essential in individuals with cystic fibrosis (CF). A literature search was conducted in MEDLINE, CENTRAL, CINAHL, PEDro, ScienceDirect and Web of Science according to PRISMA and COSMIN guidelines from inception to September 2019 to investigate the clinimetric properties of muscle tests in individuals with CF. The search identified 37 studies (1310 individuals) and 34 different muscle tests. Maximal inspiratory pressure, inspiratory work capacity and quadriceps strength measured by computerised dynamometry were identified as reliable tests of muscle function. The one-minute sit-to-stand test was found to have high reliability but its validity to measure quadriceps strength is unknown. The clinimetric properties of other routinely used tests have not been reported in people with CF. Very different measurement procedures were identified. Inspiratory muscle and quadriceps testing can be considered as reliable but high-quality studies evaluating tests of other muscles function (e.g. muscle endurance) are lacking.

Abstract
PURPOSE To provide test-retest reliability for the 6-min walk test and the physiological variables obtained during the test, and to establish the minimal detectable change for the distance walked in children and adolescents with cystic fibrosis. METHODS 40 patients performed two 6-min walk tests on the same day (separated by 30-min of rest). The perceived breathlessness and fatigue in the legs were assessed with the modified Borg scale. The peripheral muscle strength was assessed using a hand dynamometer device, the medicine ball throw test and the horizontal jump test. RESULTS The test-retest reliability of the distance walked, dyspnea and fatigue in the legs were good for children (minimal detectable change90-95: 59.39-70.55 m) and for adolescents (minimal detectable change90-95: 47.81-56.8 m) with cystic fibrosis. Exercise tolerance is more related to 6-min walk work (distance walked x body weight) than to the distance walked alone and showed a positive association with peripheral muscle strength and forced vital capacity. CONCLUSIONS The 6-min walk test is a reproducible and reliable tool to measure exercise tolerance for children and adolescents with cystic fibrosis. The minimal detectable changes reported for the distances achieved by these patients will be useful to identify the effectiveness of therapies aimed at alleviating or improving impaired physical capacity.IMPLICATIONS FOR REHABILITATIONThe 6-min walk test could be used to measure exercise tolerance for children and adolescents with cystic fibrosis, as it is a reliable test over time.An increase in the distance covered in the 6-min walk test that exceeds the minimum detectable change is recommended to determine improved exercise tolerance for children and adolescents with cystic fibrosis.The use of the 6-min walk work (distance walked x body weight) is recommended because it correlates better with exercise tolerance than the distance alone in children and adolescents with cystic fibrosis.

Abstract
OBJECTIVES Maintenance of optimal nutritional status is a crucial issue for cystic fibrosis (CF) patients. Here, we evaluate the effects of an 8-week exercise training (ET) program on body composition in CF patients. METHODS This prospective pilot observational study was conducted in adult CF subjects in stable condition following their annual check-up. The ET program consisted of three sessions per week and included aerobic training (≥30min), muscle strengthening, circuit training, and relaxation. Exercise tolerance (6-minute walk test, 6MWT), pulmonary function, quadriceps isometric strength, and body composition (bioelectrical impedance analysis of fat-free mass [FFM], fat mass, and body cell mass) were analyzed before and immediately after the ET program. A control group of CF patients who preferred not to participate in the ET program received the same evaluations. RESULTS A total of 43 CF patients were enrolled and offered the ET program; 28 accepted (aged 28±5 years, forced expiratory volume in 1s [FEV1] 48.8±19% predicted) and 15 declined the ET program but agreed to be part of the control group (matched for age and CF severity: 30.8±9 years, FEV1 51.8±16.5%). Pulmonary function was unchanged at the end of the ET program, but significant improvements were observed in 6MWT distance (from 520±96m to 562±105m, P<0.001) and muscle strength (331±141N to 379±168N, P<0.001). Although mean body mass index did not change, the ET group showed significantly increased FFM (43.85±8kg to 44.5±9.2kg, P=0.03) and a trend towards increased body cell mass (21.4±6 to 22.1±6.6kg, P=0.06). All other parameters were unchanged by ET. There were no significant correlations between the increase in FFM and the improvements in either 6MWT distance or muscle strength. The CF control group exhibited no significant changes in any parameters between evaluations. CONCLUSIONS ET significantly improved FFM, but not body mass index, in CF patients. The results illustrate the superiority of bioimpedancemetry for assessing changes in body composition and reveal the importance of ET for improving not only exercise tolerance but also nutritional status in these patients.
