| Summary: | Invasive pulmonary aspergillosis (IPA) is now been recognized as a possible secondary infection affecting COVID-19 recovery and increasing mortality. It can be explained due to factors such as direct epithelial injury, hypercoagulable and hyperinflammatory states, and the use of immunosuppressive treatment. We managed five such cases in a post-COVID intensive care unit facility at a tertiary care institute in North India. All patients had high oxygen demand, positive serum galactomannan (GM) index, and significant chest X-ray changes. All patients showed an initial improvement after receiving intravenous antifungal treatment with voriconazole. Systemic markers were suboptimal for the diagnosis of COVID-19-associated pulmonary aspergillosis (CAPA) with a sensitivity of less than 50%. GM assay has been validated in BAL and serum in numerous studies. Serum GM is a sensitive marker for IPA in patients with neutropenia; however, in nonneutropenic critically ill patients, serum GM exhibited a sensitivity of 25%, although a negative serum result cannot exclude the diagnosis of CAPA. The diagnosis of CAPA is challenging, and in patients with severe COVID-19 pneumonia may be associated with a worse prognosis. GM levels can be used for the diagnostic purpose of probable CAPA cases and administration of prophylactic treatment with voriconazole is still under debate. |
