Issues in the diagnosis and evaluation of pulmonary aspergillosis in patients with chronic obstructive pulmonary disease

Abstract

Patients with chronic obstructive pulmonary disease (COPD) may present with various forms of pulmonary aspergillosis, including invasive pulmonary aspergillosis (IPA), chronic cavitary pulmonary aspergillosis, and allergic bronchopulmonary aspergillosis. Accurate diagnosis and disease evaluation are essential for tailoring individualized treatment strategies. Key aspects include: (1) Comprehensive assessment of IPA risk factors, with enhanced monitoring for critically ill patients; (2) Understanding the clinical manifestations and radiological features of different forms of pulmonary aspergillosis and emphasizing the importance of bronchoscopic examination; (3) Obtaining microbiological evidence whenever possible; (4) Differentiating colonization from infection to avoid overdiagnosis; (5) Vigilance for co-existing sensitization to Aspergillus. During treatment and long-term disease management, the use of inhaled or systemic corticosteroids and antifungal agents should be dynamically adjusted according to the patient's condition.
