Brief summary
Bronchiectasis is a chronic bronchial disease in which the usual capacity to remove secretions does not function correctly, causing mucus retention that leads to chronic infection. As with all infections, the use of antibiotics and puss removal are essential treatment elements. Physiotherapeutic techniques are used to assist in the removal of secretions, although these are time-consuming practices that need to be much better studied and which patients often do not continue practicing diligently. A physiotherapeutic technique called (Slow prolonged expiration in lateral decubitus) ELTGOL has been shown to be somewhat effective but as the mucus is viscous in this disorder, it can be difficult to get it to move. It is thought that saline solution inhalations may reduce mucus viscosity and could help to ease expectoration, facilitating the removal of the mucus by the physiotherapeutic technique. This project aims to test this hypothesis, which if true could represent an advance in the treatment of this severely debilitating disease.
Detailed description
Bronchiectasis is a prevalent chronic infectious disease with impaired mucociliary clearance. The persistence of high bacterial loads in the bronchi is associated with airway and systemic inflammation. Management is based on treatment of bronchial infection and on removal of secretions by airway clearance techniques (ACTs) although no therapy has been approved due to low quality of evidence. Inhalation of hypertonic saline (HS) could be useful in facilitate mucus removal especially if it is administer prior an effective ACT.Our hypothesis is that the long-term combination of HS and the ELTGOL technique will facilitate secretion removal in bronchiectasis and this will be associated with changes in mucus composition and better control of the disease. Study design: A 12-month parallel-group, multicentre, double-blind randomised-controlled trial. Patients will be randomly assigned to receiving HS, isotonic saline (IS) or no inhalation before practicing ELTGOL technique. The main objective is to evaluate the effect of the combination of once-daily inhaled HS and twice daily ELTGOL technique in mucus clearance in bronchiectasis. Secondary aims: to determine its effect on mucus properties, the impact of cough,exacerbations, quality of life, microbiology and pulmonary function; to evaluate adverse effects and adherence. Study population: adult patients with non-cystic fibrosis bronchiectasis in stable state with chronic mucopurulent or purulent sputum.
Interventions
Patients from intervention group will inhale hypertonic saline solution 5 minutes before performing the morning ELTGOL technique
Patients from placebo group will inhale isotonic saline solution 5 minutes before performing the morning ELTGOL technique
Patients from control group will perform the ELTGOL technique twice-daily
