Comparisons of Inhaled LAMA or LAMA+LABA or ICS+LABA for COPD With Bronchiectasis

The Comparisons of the Efficacy and Safety of Inhaled LAMA or LAMA+LABA or ICS+LABA for Patients in COPD C Group With Bronchiectasis

The purpose of this study is to determine which treatment is more effective and safer for the patients in COPD C group with bronchiectasis.The research results will help guide physicians to select appropriate individualized treatment and hopefully provide some evidence-based medicine proofs for revising guide.

The diagnosis and treatment of COPD and bronchiectasis together seems to be more complicated than the diagnosis and treatment of either condition alone. According to the GOLD，there are three treatments for patients with COPD in group C: ICS combined with LABA or LAMA alone or LABA combined with LAMA. However, it has not yet been demonstrated about which method is more effective for the patients with COPD in group C and bronchiectasis.

This study is designed as a prospective, randomized, case-control trial. Patients are divided into three groups, one group inhaled with ICS and LABA (Symbicort), the second group inhaled with LAMA (Tiotropium Bromide) and the third group inhaled with LAMA(Tiotropium Bromide) and (Symbicort).The course of treatment is 12 months.

The investigators will also assess other relevant outcomes, including the quality of life (QOL) score, pulmonary function test and the incidence of adverse event.

Inclusion Criteria:

• Patients are suitable for inclusion in the study when they are 18 years or older diagnosed with COPD C group and bronchiectasis.

Exclusion Criteria:

• active tuberculosis
• severe respiratory disease (such as Lung cancer, ARDS, pulmonary encephalopathy, respiratory failure)
• uncontrollable diabetes
• hypersensitivity to any components of ICS/LABA or LAMA.
