Exacerbation and Training in Patients With Chronic Obstructive Pulmonary Disease

Not Applicable

Completed

• Conditions: COPD
• Interventions: Other: Usual care; Other: Resistance training

• Registration Number: NCT00877084
• Lead Sponsor: KU Leuven

Brief Summary

When patients with chronic obstructive lung disease (COPD) are admitted to the hospital with a severe exacerbation they lose muscle strength. This muscle weakness predisposes these patients to further hospital admissions. Resistance training is a potent countermeasure to prevent and treat muscle weakness. In the setting of an acute exacerbation this intervention however has not been validated.

The present study aims at investigating the safety and efficacy of resistance training (3x8 quadriceps extensions per day) to prevent muscle weakness. End points are quadriceps muscle strength and hospital readmission and functional status at discharge. Using the minimally invasive needle muscle biopsy technique described by Bergström the effects of resistance training on the skeletal muscle will be analyzed in detail.

After giving informed consent, patients will be randomized on admission into usual care or usual care plus resistance training. Patients will be followed-up using the clinical pathway for COPD (10 days). After one month patients will attend the outpatient clinic for a follow-up visit. Besides the measurement prescribed in the clinical path for COPD (including arterial blood gas measures, lung function, functional investigation of the patients), patients will undergo muscle strength measures and venous blood will be drawn for the analysis of systemic inflammatory and growth factors. Half of the patients will receive a resistance training program. At the end of the hospital admission, a needle biopsy of the vastus lateralis muscle will be obtained.

Arm && Interventions

Group	Intervention	Description
2	Usual care	Usual care according to clinical pathway for COPD exacerbations + NO training
1	Resistance training	Resistance training: series of 3x8 repetitions will be performed for the quadriceps muscle at 70% of the 1 Repetition Maximum determined as the weight the patient can lift once over the full range of motion. The weight can be applied using free weights or using a classical multi-gym device or a quadriceps chair.

Primary Outcome Measures

Time to readmission or death	6 Months
Functional exercise capacity and muscle force at 1 month	1 Month
Markers of systemic inflammation and oxidative stress in serum and muscle of patients at day 9 of the exacerbation.	Day 9
