1STST and Muscle Weakness in CF Patients

June 25, 2020 updated by: Hardy, Cliniques universitaires Saint-Luc- Université Catholique de Louvain

The 1-minute-sit-to-stand Test is Practical to Assess and Follow the Muscle Weakness in Cystic Fibrosis.

The investigators know that peripheral muscle weakness and exercise intolerance are prevalent (56%) in cystic fibrosis (Trooster et al, 2009). Physical inactivity is likely to be an important underlying factor. Those conditions are associated with a poor prognosis (Nixon et al, 1992). The effect of intravenous antibiotherapy on peripheral muscle and physical activity remains unclear.

The aim of the study is to evaluate the impact of intravenous antibiotherapy on peripheral muscular strength in patients with cystic fibrosis (adults and children) who receive intravenous antibiotherapy for an acute exacerbation or electively (decline in lung function without exacerbation).

Detailed Description

Background Peripheral muscle weakness and exercise intolerance are prevalent (56%) in cystic fibrosis (Trooster et al, 2009). Physical inactivity is likely to be an important underlying factor. Those conditions are associated with a poor prognosis (Nixon et al, 1992). The effect of intravenous antibiotherapy on peripheral muscle and physical activity remains unclear. Wieboldt et al showed that quadriceps strength at the hospital admission for an exacerbation was lower than before and one month after hospitalisation while Burtin et al showed that individual changes in quadriceps force were correlated with daily time spent activities of at least moderate intensity (Wieboldt et al, 2012; Burtin et al, 2013). The effect of intravenous antibiotherapy itself is poorly known in cystic fibrosis. Moreover, they did not study the impact on muscular strength of hospitalisation versus home treatment. In contrast, in COPD, it is well known that exacerbations are associated with a decline of muscle mass and strength and that repeated exacerbations lead to a more rapid decrease in fat free mass (Spruit et al, 2003; Jones et al, 2015; Joppa et al, 2016).

Hypothesis We think that exacerbations aggravate factors underlying muscle weakness as physical inactivity, systemic inflammation and anabolic status. Moreover, hospitalisation itself might be a reason of inactivity as patients spent all the day inside their room compared to patients who follow their treatment at home and continue their usual life.

Aim The aim of our study is to evaluate the impact of an intravenous antibiotherapy on peripheral muscular strength in patients with cystic fibrosis.

Methods We would compare patients (adults and children) who receive intravenous antibiotherapy for an acute exacerbation, with patients who receive elective intravenous antibiotherapy (decline in lung function without exacerbation). We will also compare hospitalised patients who receive specific exercise training, with patients who follow their antibiotherapy at home without specific exercise training. We will have a stable patients group as control. To evaluate muscular strength we plan to measure quadriceps force at the beginning of the cure and at the end with a functional test, the 1-minute Sit-to-Stand test and a strength (isometric) test, with the Microfet2dynamometer. Those test are not invasive, easy to realise and have already been used in other studies (Ozalevli, 2005). We will quantify the physical activity level of the patients with an accelerometer that they will carry during 72 hours, during the first week of the treatment.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

ACTIVE_COMPARATOR: Acute IV AB for exacerbation at hospital

The study will compare muscular strength of hospitalised patients who receive specific exercise training, with patients who follow their antibiotherapy at home without specific exercise training.

Interventions: microfet dynamometer, 1 minute sit to stand test, accelerometer.
Device: Microfet Dynamometer

To evaluate muscular strength, the investigators will measure quadriceps force at the beginning of the cure and at the end with a functional test, the 1-minute Sit-to-Stand test, and a maximal isometric force test, with the Microfet2dynamometer. Those tests are not invasive and easy to realise.

The investigators will estimate the physical activity of the patients with an accelerometer that they will each carry 72 hours, during the cure.

Patients who undergo their cure at the hospital will follow a specific training program with the physiotherapist.
