Immune Regulation in Chronic Aspergillus Infection After COVID-19 Infection

Inclusion Criteria: * Confirmed cases include patients diagnosed with pulmonary aspergillosis, acute or subacute Aspergillus infections, and aspergillosis in other anatomical sites (such as sinuses, middle ear, liver). Additionally, this study will enroll patients with chronic obstructive pulmonary disease (COPD), asthma, or those undergoing treatment for pulmonary tuberculosis who continue to exhibit worsening pulmonary radiological findings without a clear etiology, necessitating hospitalization or outpatient care for unexplained community-acquired pneumonia. Patients with bronchiectasis, emphysema, pulmonary fibrosis, or other chronic pulmonary conditions who are under continuous follow-up and treatment at our institution will also be included if clinically diagnosed with aspergillosis. The control group will consist of patients who, based on clinical evidence, have no history of prior exposure to Aspergillus or aspergillosis infection after contracting COVID-19. Exclusion Criteria: * Individuals aged below 20, pregnant women, patients with advanced-stage (stage II and above) lung cancer, individuals diagnosed with malignancies, patients with mental health disorders requiring consent from a legal guardian for participation, and those in critical end-stage conditions.
