Abstract
Cases of severe influenza with Aspergillus infection are commonly reported in patients with severe influenza. However, the epidemiology, risk factors, and outcomes of invasive pulmonary aspergillosis (IPA) in patients with avian influenza A (H7N9) infection remain unclear. We performed a retrospective multicenter cohort study. Data were collected from patients with avian influenza A (H7N9) infection admitted to 17 hospitals across China from February 2013 through February 2018. We found that IPA was diagnosed in 18 (5.4%) of 335 patients; 61.1% of patients with IPA (11 of 18) were identified before or within 2 days after an H7N9 virus-negative result. The median hospital stays in patients with or without IPA were 23.5 and 18 days, respectively (P < .01), and the median intensive care unit stays, respectively, were 22 and 12 days (P < .01). Smoking in the past year and antibiotic use for >7 days before admission were independently associated with IPA (adjusted odds ratio [95% confidence interval], 6.2 [1.7-26] for smoking and 4.89 [1.0-89] for antibiotic use). These findings provided important insights into the epidemiology and outcomes of IPA in patients with H7N9 infection in China.
