Post COVID Interstitial Lung Abnormalities —Incidence and Management

AbstractPurpose of ReviewThis review aims to summarize the available literature to identify the incidence and risk factors for persistent interstitial lung abnormalities (ILAs) following hospitalization for COVID-19. The current and prospective treatment options are reviewed in an effort to help pulmonary practitioners care for this burgeoning patient population.Recent FindingsStatistical modeling suggests that 11.7% of all patients hospitalized with COVID-19 have irreversible fibrotic features on long-term follow-up imaging.SummaryThe available evidence suggests that up to 30% of patients have ILAs following COVID-19 hospitalization. The radiographic abnormalities improve or resolve in a majority of these patients. However, estimates suggest that up to one-third of these patients have irreversible fibrotic features. Clinical trials of the impact of anti-fibrotic agents are ongoing. As there continue to be thousands of COVID-19 hospitalizations in the USA each week, the management of post-COVID ILAs will become a common problem for the pulmonary practitioner.
