Objective: To explore the value of circulating galactomannan (GM) screening for early diagnosis and treatment monitoring of invasive aspergillosis (IA).
Methods: Serum samples from 141 IA patients for the detection of GM by Platelia Aspergillus (Bia-Rad) were collected before and after systematic anti-fungal therapy.
Results: (1) An increase in the clinical diagnosis rate of IA was obtained on the result of GM detection. The GM positivity appeared (10+/-4.1) (8-15) d before positive sputum culture, while (12.6+/-5.7) (6-22) d before the CT positive image. (2) Among the 62 patients with consecutive serum samples, 50 were success in treatment and 12 died. A progressive decrease of GM level was found in the former group, while the rising antigen titres were found in the latter.
Conclusion: Compared with other diagnostic test, GM test has an obvious advantage of higher positivity and earlier result. The anti-fungal effectiveness can be estimated by dynamic detection of serum GM.

To evaluate the diagnostic value of metagenomic next-generation sequencing (mNGS) and galactomannan (GM) testing in invasive pulmonary aspergillosis (IPA) and to compare mNGS with other diagnostic approaches (serum/bronchoalveolar lavage fluid (BALF)-GM and conventional microbiological tests (CMTs) including sputum smears and culture, BALF fungal culture, and bronchial brushing). In all, 237 patients were enrolled in this retrospective study, including 120 patients with IPA and 117 with non-IPA pulmonary infections treated at Henan Provincial People's Hospital between June 2021 and February 2024. The diagnostic performance of mNGS was compared to conventional diagnostic methods including serum GM, BALF-GM, sputum smear microscopy, sputum culture, bronchial brushings, and BALF culture.

The importance of fungal pathogens in cystic fibrosis (CF) patients and their diagnosis remains a challenge, so our aim was to analyze the influence of the detection of fungi in sputum by using conventional culture and molecular techniques, polymerase chain reaction (PCR), lateral flow devices (LFDs), and galactomannan (GM) on exacerbations in patients with cystic fibrosis. A prospective study was conducted in patients via follow-up in the CF Unit of the Central University Hospital of Asturias from January 2021 to April 2022. Adult patients with at least one documented exacerbation were included.

Article Synopsis
- * Multi-drug resistant infections are common due to prolonged ICU stays and various medical interventions, emphasizing the importance of strict infection control practices.
- * Diagnosis relies on blood cultures, supported by specific markers for identifying types of infections, with therapy tailored based on culture results from respiratory infections.
