Summary

This is a multi-center, randomized, double-blind, parallel-group trial. After a 2-week run-in period, eligible patients will be, based on the randomization codes kept in sealed envelopes, randomly assigned to receive usual care (mucolytics and/or chest physiotherapy) plus oxygen inahaltion (1 hr daily for 12 consecutive months) or hydrogen inhalation (1 hr daily for 12 consecutive months) provided by the sponsor. At 3 months after the end-of-treatment, a follow-up visit will be scheduled for all patients.

Detailed description

This is a multi-center, randomized, double-blind, parallel-group trial. After 2-week run-in period, eligible patients will be, based on the randomization codes kept in sealed envelopes, randomly assigned to two groups.On the basis of usual care \[ambroxool (30mg thrice daily), or N-acetylcysteine (0.2g thrice daily)/ serrapeptase (10mg thrice daily), or carbocisteine (500mg thrice daily) and/or chest physiotherapy (10 min, twice daily)\], patients were randomized to receive either hydrogen (66.7%, 3L/min, 1 hr twice daily) inhalation or oxygen inhalation (3L/min, 1 hr twice daily) via nasal canula for 12 months. A follow-up visit at month 3 following end-of-treatment was also scheduled. The primary endpoint was the annual frequency of bronchiectasis exacerbations. Hospital visits were scheduled at baseline and months 1, 3, 6, 9, 12 and 15, respectively. At 3 months after the end-of-treatment, a follow-up visit will be scheduled for all patients.

Conditions

• Bronchiectasis
• Acute Exacerbation of Bronchiectasis
• Oxidative Stress

Interventions

Type	Name	Description
DEVICE	medical ultrasonic hydrogen/oxygen nebulizer (MUNHO)	The medical ultrasonic nebulizers with hydrogen/oxygen generating function (MUNHO) will be provided exclusively by the sponsor, Asclepius Meditec Inc (Shanghai, China). The MUNHO consists of a electrolytic tank which, by using direct current converted from alternating current (220 V), generates the hydrogen and oxygen gas from pure water (2:1 in volume). The MUNHO is also capable of nebulizing the water via ultrasounds with the hydrogen-oxygen mixed gas which is finally delivered to the patient's airways via the facial mask through a plastic tube. Typically, the volume of hydrogen-oxygen mixed gas is 3 liters per minute (3 L/min).
DEVICE	Medical molecular mesh oxygen generator	medical molecular mesh oxygen generator, type: OLO-1, oxygen flow: 3L/min; Shanghai Ouliang Medical Instrument Inc., Shanghai, China; Registration No.: Shanghai Medical Instrument approval No. 20152540046. This device has an identical appearance as compared with the MUHNO so that the patients could not readily discriminate with the MUHNO, and is also capable of displaying the actual cumulative duration of oxygen inhalation.
