Abstract:
We encountered a patient with severe coronavirus disease 2019 (COVID-19)-related pneumonia, who died of progressive respiratory acidosis after 2 months of treatment with mechanical ventilation. The autopsy revealed diffuse alveolar damage (DAD) without any active signs of fungal or bacterial infections, suggesting prolonged and over-activated immune responses against COVID-19 infection. When COVID-19 patients develop acute respiratory distress syndrome, it is essential to remember that the infection can progress to DAD a few months after the disease onset.

COPD: Pathogenesis and Clinical Features
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
