Coronavirus disease 2019 (COVID-19) pandemic has been prevailing for more than a year, associated with an increased number of opportunistic invasive fungal infections in patients who have been critically ill or immunocompromised. In this retrospective study, details of various clinical specimens received from suspected patients of fungal infections were studied. Fungal cultures were positive in 64% (51 out of 79) of COVID-19-positive patients and 43% (163 out of 381) of COVID-19-negative patients during the second wave of COVID-19 in 2021.

Objective: This study was conducted to further understand the clinical characteristics of COVID-19 associated pulmonary aspergillosis (CAPA).
Methods: In this study, we conducted a multicenter retrospective survey, which included patients with COVID-19 from five hospitals in Zhejiang, China. A total of 197 patients with COVID-19 were included in the study.

An accurate diagnosis of invasive aspergillosis (IA) in patients with underlying hematological malignancies relies heavily on galactomannan detection. In this study, we compared the VirCLIA chemiluminescence immunoassay (CLIA) with the frequently used Platelia enzyme-linked immunosorbent assay (ELISA) on serum from hematology patients with suspected IA. Patients were categorized according to EORTC/MSGERC 2020 definitions into proven/probable IA and possible/no IA.

Background And Objective: Multiplex polymerase chain reaction (PCR)-based targeted next-generation sequencing (tNGS) is a promising tool for distinguishing lower respiratory tract infections (LRTIs) in clinical practice, and its detectable pathogen spectrum can cover more than 95% of clinical cases. but there is limited information on systematic evaluation of the clinical use of multiplex PCR-based tNGS (mp-tNGS) in IPA cases. We aim to assess mp-tNGS in bronchoalveolar lavage fluid (BALF) for Aspergillus detection in suspected IPA patients, and to provide a reliable basis for initiating antifungal therapy without microbiological or histopathological evidence.

Invasive pulmonary infections are a significant cause of morbidity and mortality in patients with hematological malignancies and hematopoietic stem cell transplantation (HCT) recipients. A delay in identifying a causative agent may result in late initiation of appropriate treatment and adverse clinical outcomes. We examine the diagnostic utility of PCR-based assays in evaluating invasive pulmonary infections from bronchoalveolar lavage (BAL).
