Organizing pneumonia: A late phase complication of COVID-19 responding dramatically to corticosteroids.
Organizing pneumonia emerges as a late phase complication of COVID-19. Corticosteroids are standard therapy for organizing pneumonia, but the question of whether an approach with high dose corticosteroids would be beneficial for patients with organizing pneumonia secondary to COVID-19 remains to be answered. Herein we report a series of three patients, one male and two females, mean age 58.3 years old, admitted for COVID-19 with severe pulmonary disease requiring ventilatory support. ⋯ The patients were treated with a high dose of corticosteroids (prednisone 1 mg/kg PO), showing marked clinical improvement, and decreasing oxygen flow ratio demand. They were discharged after a mean period of 6.3 days of hospitalization. Our report suggests that patients with COVID-19 with organizing pneumonia might benefit from high dose corticosteroids as an adjuvant therapy.

COVID-19 has raised worldwide concern as spiraling into a pandemic. Reports about comprehensive investigation of COVID-19 viremia are extremely scanty. Herein, we present four COVID-19 patients with positive SARS-CoV-2 nucleic acid test in blood, accounting for 12.12% of 33 detected cases. ⋯ It indicates that massive replication and releasing into blood of SARS-CoV-2 and secondary inflammation storm may lead to injury of multiple organs and poor prognosis. So, positive COVID-19 nucleic acid test in blood may be a good forecasting marker of rapid deterioration of COVID-19 pneumonia. In addition, clearance of viremia may indicate tendency for recovery.

During SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2) pandemic, the etiologic agent of COVID-19, several studies described the involvement of other tissues besides the respiratory tract, such as the gastrointestinal tract. Angiotensin-converting enzyme-2, the functional virus host cell receptor expressed by organs and tissues, seems to have an important role in the pathophysiology and presentation of this disease. ⋯ Diagnosing acute pancreatitis secondary to SARS-CoV-2 infection is challenging due to the need to rule out other etiologies as well the notable heterogeneous presentations. Herein we report the case of a patient with COVID-19 who developed severe acute pancreatitis.

There is scarce information on the human immune response to the SARS-CoV-2 infection, and on the exacerbated inflammatory reaction observed in severe COVID-19 cases. ⋯ Due to their central role in immune response against SARS-CoV-2 infection, IFN type I and III could be considered for treatment of COVID-19.
