Brief Title
Effect of AIRVO Heated Humidification in Bronchiectasis
Official Title
Multicenter, Pragmatic, Randomized, Controlled Trial to Assess the Efficacy and Safety of Nocturnal Humidification Therapy in Patients With Bronchiectasis: the AIRVO-BX Study
Brief Summary
The aim of the study is to investigate whether long-term heated humidification therapy
(AIRVO) administrated for 1 year over-night on top of standard therapy can reduce the number
of exacerbations in adults with non-cystic fibrosis bronchiectasis.
Detailed Description
Bronchiectasis is a chronic condition characterized by an abnormal widened airways, mucus
retention, cough, daily sputum, and frequent respiratory infections. The management of
bronchiectasis includes prevention of exacerbations and lung infections along with airway
clearance techniques.
Mucus composition and hydration are crucial to allow mucus transport along airways during
respiratory physiotherapy.
Previous studies showed that long term humidification therapy increased airway clearance
(Hasani et al. 2008) and reduced the number of exacerbations in patients with both
bronchiectasis and Chronic Obstructive Pulmonary Disease (COPD) (Rea et al. 2010). myAIRVO2
system can deliver high-flow warm and humidified gases through a nasal cannula.
The aim of the present study to assess the effect of long-term use over-night of myAIRVO2
warm humidification in adults with bronchiectasis who experience at least 3
exacerbations/year still with optimized clinical and respiratory therapies.
In addition to their usual therapy, the treatment group will receive a myAIRVO2 humidifier at
home deliver every day for one year over-night.
The gas flow setting will be set between 20 and 30 l/min based on patient preference,
temperature will be 37°C and, for patients already in long-term oxygen therapy, FiO2 will be
regulated according to patient's prescription.
The control group will continue to receive standard therapy for bronchiectasis according to
international guidelines.
Patients will be screened during outpatient visits and, if they meet study criteria, they
will be enrolled in the study. Once enrolled in the study, patients will be followed up every
3 months with 4 consecutive outpatient visits. The following endpoints will be assessed:
exacerbations frequency, quality of life, pulmonary function and, for patients enrolled in
the treatment group, myAIRVO2 use, and comfort.
Statistical analysis will be performed by Prof. Giovanni Sotgiu (University of Sassari -
Italy).
