Bronchiectasis With Acute Exacerbation
Conditions
Keywords
Bronchiectasis, Bronchoscopy, Levofloxacin, Gentamicins, Steroids
Brief summary
Randomized single-center trial evaluating whether bronchoscopic instillation of levofloxacin or gentamicin improves outcomes compared to a sham bronchoscopic procedure in adult ICU patients with non-cystic fibrosis bronchiectasis requiring invasive mechanical ventilation. The primary outcome is a ranked composite of in-hospital mortality and time to ventilator liberation. Safety and procedural adverse events are closely monitored.
Detailed description
Bronchiectasis is a chronic suppurative and inflammatory lung disease of diverse etiology characterized by pathological and irreversible dilatation of the bronchial tree. The impairment of the mucociliary clearance, which results from chronic airway inflammation, may cause long-term colonization or recurrent infection of bacteria, especially Pseudomonas aeruginosa (PA), while bacterial colonization and recurrent infection can aggravate airway inflammation. Sputum retention caused by the impairment of mucociliary clearance can result in mucous plugs, which in turn contribute to airflow obstruction and dyspnea. Clinically, the major manifestations of bronchiectasis include chronic cough with purulent sputum, dyspnea, and fatigue, which can significantly diminish patients' quality of life. The frequency of exacerbations and decline in lung function may lead to a poor prognosis and a decrease in quality of life. The purpose of bronchiectasis management is to reduce exacerbations, prevent complications, and improve the quality of life. Long-term instillation of antibiotics and steroids can reduce the concentration of bacteria in the airways, decrease sputum production, attenuate lung function decline, and reduce acute pulmonary exacerbations without nephrotoxicity or ototoxicity. Dexamethasone is one of the most common glucocorticoids that can inhibit the expression levels of inflammatory factors in the airway and reduce the secretion of airway mucus. Topical administration could also reduce the systemic side effects.
Interventions
Bronchoscopic local instillation of gentamicin and Budesonide
Bronchoscopic local instillation of Levofloxacin and Budesonide
Bronchoscopic mechanical secretion suction and lavage
Bronchoscopy for airway visualization only, no lavage or drug instillation (sham procedure).

Masking description
Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor) All participants, clinical care providers (including bedside staff), investigators, and outcomes assessors will be blinded to group allocation. The use of a sham bronchoscopic procedure in the control arm ensures that all patients undergo a procedure of similar appearance and duration, minimizing the risk of performance and detection bias. Unblinding will only occur in the event of medically necessary interventions during the sham procedure, which will be documented as protocol deviations while maintaining the intention-to-treat analysis.
Intervention model description
Arm 1: Levofloxacin Bronchoscopic instillation of levofloxacin 500 mg in isotonic saline during standardized bronchoscopy. Arm 2: Gentamicin Bronchoscopic instillation of gentamicin 80 mg in isotonic saline during standardized bronchoscopy. Arm 3: Sham Bronchoscopy for airway visualization only, no lavage or drug instillation (sham procedure).
