Invasive aspergillosis a complication severe respiratory viral infections (influenza and COVID-19)

Abstract

Invasive aspergillosis is a life-threatening complication in patients with severe influenza and COVID-19 in intensive care units. Risk factors for the invasive aspergillosis development are transitory immunosuppression associated with severe influenza and COVID-19, as well as the use of glucocorticosteroids and immunosuppressive therapy. In the presence of risk factors, suspected clinical and radiological signs of invasive aspergillosis, bronchoscopy and examination of material from the lower respiratory tract are necessary: test for galactomannan, microscopy with white calcofluor staining and inoculation on Sabouraud agar medium. Voriconazole or are recommended as first-line treatment for invasive aspergillosis in patients with severe influenza and COVID-19. Amphotericin B Liposomal, Amphotericin B Lipid Complex, and Caspofungin are the alternative options for the invasive aspergillosis treatment. Combination therapy is possible. It is necessary to control the underlying disease with eliminate or reduce the severity of risk factors.
