Aim: To assess the impact of Aspergillus PCR on managing invasive aspergillosis (IA) in routine patient management.
Methods: A retrospective study included 235 patients who had Aspergillus PCR tests performed on respiratory samples (bronchoalveolar lavage, non-bronchoscopic lavage, and sputum) from November 2020 to April 2022.
Results: Of 293 tests, 11.9% were PCR positive. Positive PCR results did not alter IA diagnostic categories. The decision on antifungal treatment was based on PCR results in nine of the 54 treated patients. Ten patients with positive PCR were not treated due to clinical improvement while awaiting results.
Conclusion: The utility of Aspergillus PCR was constrained by the use of non-validated samples and delays in reporting, reducing its impact on management decisions during a time when bronchoscopy was limited due to COVID-19. To enhance its clinical effectiveness and cost-efficiency, implementing a diagnostic algorithm for appropriate use is essential.

Kojic acid is a secondary metabolite with strong chelating and antioxidant properties produced by and . Although antioxidants and chelators are important virulence factors for plant pathogens, the ecological role of kojic acid remains unclear. We previously observed a greater gene expression of antioxidants, especially kojic acid, by non-aflatoxigenic when co-cultured with aflatoxigenic Aflatoxin production was also reduced.

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.

Coronavirus disease 2019 (COVID-19)-associated pulmonary aspergillosis (CAPA) is a life-threatening complication in patients with severe COVID-19. Previously, acute respiratory distress syndrome in patients with COVID-19 has been associated with lung fungal dysbiosis, evidenced by reduced microbial diversity and colonization. Increased fungal burden in the lungs of critically ill COVID-19 patients is linked to prolonged mechanical ventilation and increased mortality.
