Diagnosis of invasive pulmonary aspergillosis (IPA) is challenging. The objective of the study was to assess the value of microbiological tests to the diagnosis of IPA in the absence of non-specific radiological data. A retrospective study of 23 patients with suspicion of IPA and positivity of some microbiological diagnostic tests was performed. These tests included conventional microbiological culture, detection of Aspergillus galactomannan (GM) antigen and in some patients (1 → 3)-β-D-glucan (BDG) and Aspergillus fumigatus DNA using the LightCycler SeptiFast test. In 10 patients with hematological malignancy, 6 cases were considered 'probable' and 4 'non-classifiable.' In 8 patients with chronic lung disease, 7 cases were classified as 'probable' and 1 as 'proven,' and in 5 patients with prolonged ICU stay (>7 days), there were 2 'proven' cases, 2 'non-classifiable' and 1 putative case. Microbiological culture was positive in 17 cases and 18 Aspergillus spp. were isolated (one mixed culture). A. fumigatus was the most frequent (44.4%) followed by A. tubingensis. The Aspergillus galactomannan (GM) antigen assay was positive in 21 cases (91.3%). The GM antigen and the (1 → 3)-β-D-glucan (BDG) assays were both performed in 12 cases (52.2%), being positive in 9. The SeptiFast test was performed in 7 patients, being positive in 4. In patients with non-classifiable pulmonary aspergillosis and one or more positive microbiological tests, radiological criteria may not be considered a limiting factor for the diagnosis of IPA.

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).

Invasive infections with Aspergillus fumigatus in ICU patients are linked to high morbidity and mortality. Diagnosing invasive pulmonary aspergillosis (IPA) in non-immunosuppressed patients is difficult, as Aspergillus antigen (galactomannan [GM]) may have other causes. This retrospective study analyzed 160 ICU surgical patients with positive GM in broncho-alveolar lavage fluid (BALF), classifying them based on AspICU criteria for suspected IPA (pIPA) or aspiration.

The epidemiology of allergic bronchopulmonary aspergillosis (ABPA) in the United States is not well-described. To estimate national ABPA prevalence among patients with asthma or cystic fibrosis, characterize ABPA testing practices, and describe ABPA clinical features, treatment, and 6-month outcomes. We used the 2016-2022 Merative™ MarketScan® Commercial/Medicare and Multi-State Medicaid Databases to identify cohorts of patients with 1) asthma, 2) cystic fibrosis (CF), and 3) ABPA.

Hyperimmunoglobulin E syndrome (HIGES) is a rare immunodeficiency characterized by high levels of immunoglobulin E (IgE) in the setting of various clinical features such as cutaneous candidiasis, asthma, recurrent rashes, and fungal infections. This case describes a 70-year-old male with cachexia and dyspnea found to have a cavitary lesion and aspergilloma, with remarkably high IgE and positive 1,3-β-D-glucan and Aspergillus testing. Herein, we describe the aforementioned case, review the available literature, and hypothesize the connection between invasive fungal infections and HIGES.

Background: Chronic pulmonary abscess usually results from bacterial or mycobacterium infection, but rarely from aspergillosis. Chronic pulmonary aspergillosis is usually found in a person with structural lung disease or immunocompromise. Here, we report a case of chronic lung abscess of aspergillosis without immunocompromise, structural lung diseases or even clinical symptoms.
