Clinical Trial 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.


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.

Outcome

Type Measure Description Time frame Safety issue
Primary Bacterial Clearance Rate of Sputum 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. after 14 days
Secondary Total Sputum Weight (Collected Over 24 h) After 14 Days of Treatment after 14 days
Secondary Sputum Property Score After 14 Days of Treatment 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. after 14 days
Secondary Forced Expiratory Volume in One Second (FEV1) (Percent of Predicted for Age) After 14 Days of Treatment after 14 days
Secondary Forced Expiratory Volume in One Second (FEV1) After 14 Days of Treatment after 14 days
