Combined Administration of Nebulized Amikacin in Patients With Acute Exacerbation of Non-Cystic Fibrosis Bronchiectasis
- Conditions
- Non-Cystic Fibrosis Bronchiectasis
- Interventions
- Drug: Normal saline
- Registration Number
- NCT02081963
- Lead Sponsor
- Qilu Hospital of Shandong University
- Brief Summary
This is a multi-centered, randomized, controlled study to assess the efficacy, indications and adverse reactions of combined administration of nebulized amikacin in patients with acute exacerbation of non-cystic fibrosis bronchiectasis and to evaluate whether inhaled antibiotics are more likely to cause bacterial resistance.
- Detailed Description
Objective: To assess the efficacy, indications and adverse reactions of combined administration of nebulized amikacin in patients with acute exacerbation of non-cystic fibrosis bronchiectasis and to evaluate whether inhaled antibiotics are more likely to cause bacterial resistance.
Methods: Patients with acute exacerbation of non-cystic fibrosis bronchiectasis will be randomly assigned to the observer group (participants receive nebulized amikacin BID for 14 days in combination with standard treatment) or the control group (participants receive nebulized 0.9% saline BID for 14 days in combination with standard treatment). The primary endpoint was bacterial clearance rate of sputum.
Expected results: Compared with the control group, bacterial clearance rate of sputum of the observer Group will increase significantly.

Group Intervention Description Nebulized normal saline Normal saline Participants received nebulized normal saline BID for 14 days in combination with standard treatment. Nebulized amikacin Amikacin Participants receive nebulized amikacin BID for 14 days in combination with standard treatment.
- Primary Outcome Measures
Name Time Method Bacterial Clearance Rate of Sputum after 14 days The bacterial eradication rate of the sputum was calculated by the number of P. aeruginosa-eradicated cases according to sputum culture testing result. Sputum samples were collected in the morning after toothbrushing and gargling, before the patients used any medicine. Eligible sputum samples were defined as having ≥25 white blood cells/highpower field and ≤10 epithelial cells/high-power field; the samples were sent for testing within 60 min. Sputum samples were collected again after 14 days. If the second sputum culture test showed a negative result after the first one had been positive, it was defined as eradicated.
- Secondary Outcome Measures
Name Time Method Forced Expiratory Volume in One Second (FEV1) After 14 Days of Treatment after 14 days Total Sputum Weight (Collected Over 24 h) After 14 Days of Treatment after 14 days Sputum Property Score After 14 Days of Treatment after 14 days The sputum properties were graded from 1 to 4, with 1 being assigned to transparent mucous sputum, 2 to yellow purulent sputum, 3 to green purulent sputum, and 4 to black green purulent sputum. Higher scores mean a worse outcome.
