A Silent Threat in Post-Tuberculosis Patients: Chronic Pulmonary Aspergillosis Survey in Multiple Regions of Indonesia (I-CHROME Study)

Résumé fourni par la source

Background: A significant complication among post-tuberculosis patients is chronic pulmonary aspergillosis (CPA), with prevalence and outcomes varying by region. This study aimed to explore the epidemiology, clinical characteristics, and microbiological profiles of 219 post-tuberculosis patients with persistent respiratory symptoms and lung cavities in Indonesia. Methods: The patients were divided into CPA (n = 144) and non-CPA (n = 75) groups. This cross-sectional study diagnosed CPA in post-tuberculosis patients using ERS/ESCMID criteria, integrating clinical, radiological, and fungal assessments. Serological tests for Aspergillus-specific IgG were conducted using immunochromatographic (ICT) and ELISA on serum samples. Sputum specimens were used in parallel for fungal culture, and radiological evaluations (e.g., chest X-rays or CT scans) were performed to identify typical CPA features such as cavitation and fibrosis. Results: Persistent cough was significantly more common in CPA patients (83.3%, p = 0.015), highlighting its role as a clinical indicator for CPA. Radiological infiltrates were found in 165 patients (75.3%); critical diagnostic markers of CPA were cavitation and pericavitary fibrosis. Aspergillus-specific IgG testing demonstrated high diagnostic utility, with positivity rates of 69.4% for ICT and 63.2% for ELISA among CPA patients. Among those with infiltrates, a positive Aspergillus culture was not more common (p > 0.05), whereas Aspergillus IgG was more often raised (p = 0.037), as was a positive ICT (p = 0.021). Regional analysis revealed a higher CPA burden in Region 1 (75%) compared to Region 2 (56%, p = 0.003), with Aspergillus fumigatus and Aspergillus niger predominating in Region 1. Conclusions: These findings highlight the importance of comprehensive approaches and region-specific CPA management strategies in Indonesia.
