RESUMEN

Acute respiratory distress syndrome remains the main cause of death among people with COVID-19. Although many immunomodulatory and antiviral drug therapies have been tested, the only effective therapy against severe COVID-19 pneumonia among the general population is a regimen of high-dose corticosteroids for cases of severe associated inflammation. In solid-organ transplant recipients with long-term immunosuppression, data on disease presentation and evolution are scarce, and the benefit of high-dose corticosteroids remains uncertain for cases of severe COVID-19 pneumonia. Here, we report 2 cases of COVID-19-related acute respiratory distress syndrome that occurred in lung transplant recipients in March and April 2020, respectively. Both cases of acute respiratory distress syndrome occurred in patients with long-term azithromycin treatment prescribed to prevent chronic allograft dysfunction. Acute respiratory distress syndrome was associated with severe inflammation and was cured after early administration of high-dose corticosteroids in both cases, with progressive and complete resolution of lung lesions evidenced on thoracic computed tomography scan. Our findings support the benefit of early high-dose corticosteroids in COVID-19-related acute respiratory distress syndrome with hyperinflammation in patients with long-term immunosuppression such as lung transplant recipients.

RESUMEN

(1) Background: The diagnosis of invasive aspergillosis (IA) in an intensive care unit (ICU)remains a challenge and the COVID-19 epidemic makes it even harder. Here, we evaluatedAspergillus PCR input to help classifying IA in SARS-CoV-2-infected patients. (2) Methods: 45COVID-19 patients were prospectively monitored twice weekly for Aspergillus markers and anti-Aspergillus serology. We evaluated the concordance between (Ι) Aspergillus PCR and culture inrespiratory samples, and (ΙΙ) blood PCR and serum galactomannan. Patients were classified asputative/proven/colonized using AspICU algorithm and two other methods. (3) Results: Theconcordance of techniques applied on respiratory and blood samples was moderate (kappa = 0.58and kappa = 0.63, respectively), with a higher sensitivity of PCR. According to AspICU, 9/45 patientswere classified as putative IA. When incorporating PCR results, 15 were putative IA because theymet all criteria, probably with a lack of specificity in the context of COVID-19. Using a modifiedAspICU algorithm, eight patients were classified as colonized and seven as putative IA. (4)Conclusion: An appreciation of the fungal burden using PCR and Aspergillus serology was addedto propose a modified AspICU algorithm. This proof of concept seemed relevant, as it was inagreement with the outcome of patients, but will need validation in larger cohorts.
