Anti-inflammatory Effects of Macrolide Treatment in Influenza Lower Respiratory Tract Infections
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
Objectives: (1) We aim to investigate the anti-inflammatory effects of macrolide treatment in patients with influenza LRTI and the impact on viral clearance. (2) To investigate the impact of macrolide treatment on influenza symptom and disease resolution.
Design: A randomized, open-label, multicenter study.
Settings: Acute medical facilities in 3 general public hospitals in Hong Kong.
Subjects, Sampling and Intervention: Adult (>/=18 years) patients hospitalized for virologically confirmed influenza LRTI who fulfill the inclusion/exclusion criteria will be randomized to receive (1) azithromycin 500 mg p.o. for 5 days (in addition to antiviral, as part of usual care), or (2) no azithromycin (ie, antiviral alone, part of usual care) after informed consent. Serial blood samples will be collected for cytokine/inflammatory response assays. Serial nasopharyngeal swabs will be collected to assess for viral clearance. Symptoms, clinical progress, radiography and adverse events will be monitored.
