| Cohort | In our study, all of the patients were admitted to a respiratory intensive care unit (RICU) because of respiratory failure from February 2009 to December 2009. These patients were older than 18 years and had been diagnosed with severe COPD, stage III or IV according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD). Patients were excluded for: (i) concurrent solid organ tumor; (ii) concurrent hematological system diseases; (iii) organ transplantation; (iv) long-term use of glucocorticoids for reasons other than COPD; and (v) receiving radiation therapy or immunosuppressive drugs. Of 50 critically ill COPD patients admitted, BALF and serum samples were collected in 34 patients. |

| Disease Introduction Mechanism | Invasive pulmonary aspergillosis (IPA) is an important cause of mortality in imunocompromised populations, such as hematological and solid-organ transplant patients. In recent years, chronic obstructive pulmonary disease (COPD) patients, especially those who are critically ill and are admitted to an ICU, are being increasingly recognized as belonging to a population at particular risk of IPA. Timely diagnosis of IPA in this population is challenging due to a lack of specific signs and symptoms, which contributes to a high mortality of 67% to 100%. |
