Background: COVID‐19‐associated pulmonary aspergillosis (CAPA) has been widely reported but homogenous large cohort studies are needed to gain real‐world insights about the disease. Methods: We collected clinical and laboratory data of 1161 patients hospitalised at our Institute from March 2020 to August 2021, defined their CAPA pathology, and analysed the data of CAPA/non‐CAPA and deceased/survived CAPA patients using univariable and multivariable models. Results: The overall prevalence and mortality of CAPA in our homogenous cohort of 1161 patients were 6.4% and 47.3%, respectively. The mortality of CAPA was higher than that of non‐CAPA patients (hazard ratio: 1.8 [95% confidence interval: 1.1–2.8]). Diabetes (odds ratio [OR] 1.92 [1.15–3.21]); persistent fever (2.54 [1.17–5.53]); hemoptysis (7.91 [4.45–14.06]); and lung lesions of cavitation (8.78 [2.27–34.03]), consolidation (9.06 [2.03–40.39]), and nodules (8.26 [2.39–28.58]) were associated with development of CAPA by multivariable analysis. Acute respiratory distress syndrome (ARDS) (2.68 [1.09–6.55]), a high computed tomography score index (OR 1.18 [1.08–1.29]; p <.001), and pulse glucocorticoid treatment (HR 4.0 [1.3–9.2]) were associated with mortality of the disease. Whereas neutrophilic leukocytosis (development: 1.09 [1.03–1.15] and mortality: 1.17 [1.08–1.28]) and lymphopenia (development: 0.68 [0.51–0.91] and mortality: 0.40 [0.20–0.83]) were associated with the development as well as mortality of CAPA. Conclusion: We observed a low but likely underestimated prevalence of CAPA in our study. CAPA is a disease with high mortality and diabetes is a significant factor for its development while ARDS and pulse glucocorticoid treatment are significant factors for its mortality. Cellular immune dysregulation may have a central role in CAPA from its development to mortality. [ABSTRACT FROM AUTHOR]

Abstract Invasive pulmonary aspergillosis (IPA) has always been a challenging diagnosis and risk factors an important guide to investigate specific population, especially in Intensive Care Unit. Traditionally recognized risk factors for IPA have been haematological diseases or condition associated with severe immunosuppression, lately completed by chronic conditions (such as obstructive pulmonary disease, liver cirrhosis, chronic kidney disease and diabetes), influenza infection and Intensive Care Unit (ICU) admission. Recently, a new association with SARS-CoV2 infection, named COVID-19-associated pulmonary aspergillosis (CAPA), has been reported worldwide, even if its basic epidemiological characteristics have not been completely established yet. In this narrative review, we aimed to explore the potential risk factors for the development of CAPA and to evaluate whether previous host factors or therapeutic approaches used in the treatment of COVID-19 critically ill patients (such as mechanical ventilation, intensive care management, corticosteroids, broad-spectrum antibiotics, immunomodulatory agents) may impact this new diagnostic category. Reviewing all English-language articles published from December 2019 to December 2020, we identified 21 papers describing risk factors, concerning host comorbidities, ICU management, and COVID-19 therapies. Although limited by the quality of the available literature, data seem to confirm the role of previous host risk factors, especially respiratory diseases. However, the attention is shifting from patients’ related risk factors to factors characterizing the hospital and intensive care course, deeply influenced by specific features of COVID treatment itself. Prolonged invasive or non-invasive respiratory support, as well as the impact of corticosteroids and/or immunobiological therapies seem to play a pivotal role. ICU setting related factors, such as environmental factors, isolation conditions, ventilation systems, building renovation works, and temporal spread with respect to pandemic waves, need to be considered. Large, prospective studies based on new risk factors specific for CAPA are warranted to guide surveillance and decision of when and how to treat this particular population.

Coronavirus disease-2019 (COVID-19) causes severe pneumonia and acute respiratory distress syndrome. According to the current consensus, immunosuppressants, such as dexamethasone and anti-interleukin-6 receptor monoclonal antibodies, are therapeutic medications in the early stages of infection. However, in critically ill patients, viral, fungal, and bacterial coinfection results in higher mortality. We conducted a single-center, retrospective analysis of 29 mechanically ventilated patients with artificial airways. Patients were adults with confirmed COVID-19 infection and severe pneumonia. Acute respiratory distress syndrome was diagnosed according to the Kigali modification of the Berlin definition. Six patients had invasive pulmonary aspergillosis coinfection based on elevated serum galactomannan levels and/or bronchoalveolar lavage fluid. We present two cases with brief histories and available clinical data. We also conducted a literature review to determine whether immunosuppressants, such as tocilizumab, increase infection risk or invasive aspergillosis in patients with COVID-19. There is no conclusive evidence to suggest that tocilizumab increases coinfection risk. However, further studies are needed to determine the optimal dose, between-dose interval, and timing of tocilizumab administration in patients with COVID-19. [ABSTRACT FROM AUTHOR]

We report four cases of invasive pulmonary aspergillus co‐infection in patients with coronavirus disease 2019 (COVID‐19) infection and acute respiratory distress syndrome requiring intensive care unit (ICU) admission. Aspergillus fumigatus and Aspergillus terreus were isolated, with early infection onset following ICU admission. Clinicians should be aware of invasive pulmonary aspergillosis in ICU patients with COVID‐19 infection, particularly those receiving dexamethasone. We propose screening of these high‐risk patients with twice‐weekly fungal culture from tracheal aspirate and, if feasible, Aspergillus polymerase chain reaction. Diagnosis is challenging and antifungal treatment should be considered in critically ill patients who have new or worsening pulmonary changes on chest imaging and mycological evidence of infection.

The recent global outbreak of coronavirus disease-19, also known as COVID-19, has infected more than 142 million people worldwide, causing more than 3 million deaths. It has been shown that up to 40% of hospitalized COVID-19 patients may develop ARDS. Although not proven, anti-inflammatory and anti-cytokine treatments are recommended to suppress the cytokine storm that develops in the early stages of the disease. In this case report, a case of pulmonary aspergillus developed as a complication of treatment for ARDS caused by covid 19 in a 50-year-old male patient will be presented in the light of current literature.
