Background: Bruton Tyrosine Kinase inhibitor (BTKi) emerged as key treatment for B-cell lymphomas. Despite its efficacy in the treatment of malignancies, numerous cases of invasive fungal infections (IFI) have been reported in patients receiving ibrutinib, a first generation BTKi. Cases of invasive aspergillosis have also been reported with acalabrutinib and zanubrutinib.

Article Synopsis
  • Ibrutinib, a first-generation BTK inhibitor, increases the risk of invasive fungal infections, while the second-generation BTK inhibitor, acalabrutinib, has unknown effects on neutrophil antifungal activity despite only a few reported cases of aspergillosis during its use.
  • Three new cases of invasive aspergillosis were identified in patients with chronic lymphocytic leukemia shortly after starting acalabrutinib therapy, raising concern about its impact on immune response.
  • After one month of acalabrutinib treatment, neutrophils exhibited a reduced ability to fight against Aspergillus fumigatus, highlighting the need for close monitoring of patients on this medication for potential fungal infections.

Autoantibodies (auto-Abs) neutralizing type I interferons (IFNs) are found in the blood of at least 15% of unvaccinated patients with life-threatening COVID-19 pneumonia. We report here the presence of auto-Abs neutralizing type I IFNs in the bronchoalveolar lavage (BAL) of 54 of the 415 unvaccinated patients (13%) with life-threatening COVID-19 pneumonia tested. The 54 individuals with neutralizing auto-Abs in the BAL included 45 (11%) with auto-Abs against IFN-α2, 37 (9%) with auto-Abs against IFN-ω, 54 (13%) with auto-Abs against IFN-α2 and/or ω, and five (1%) with auto-Abs against IFN-β, including three (0.

Identifying fungal clones propagated during outbreaks in hospital settings is a problem that increasingly confronts biologists. Current tools based on DNA sequencing or microsatellite analysis require specific manipulations that are difficult to implement in the context of routine diagnosis. Using deep learning to classify the mass spectra obtained during the routine identification of fungi by MALDI-TOF mass spectrometry could be of interest to differentiate isolates belonging to epidemic clones from others.

is an emerging pathogen which recently spread from India to Europe and that is more prone than other species of the complex to show resistance to terbinafine, resulting in the necessity of rapid identification. Here, we improved the online MSI-2 MALDI-TOF identification tool in order to identify . By multiplying the culture conditions (2 culture media and 6 stages of growth) prior to protein extractions for both test isolates and reference strains, we added 142 references corresponding to 12 strains inside the complex in the online MSI-2 database, of which 3 are strains.
