CT-based Assessment at 6-Month Follow-up of COVID-19 Pneumonia patients in China.

Publication date: Feb 29, 2024

This study aimed to assess pulmonary changes at 6-month follow-up CT and predictors of pulmonary residual abnormalities and fibrotic-like changes in COVID-19 pneumonia patients in China following relaxation of COVID restrictions in 2022. A total of 271 hospitalized patients with COVID-19 pneumonia admitted between November 29, 2022 and February 10, 2023 were prospectively evaluated at 6 months. CT characteristics and Chest CT scores of pulmonary abnormalities were compared between the initial and the 6-month CT. The association of demographic and clinical factors with CT residual abnormalities or fibrotic-like changes were assessed using logistic regression. Follow-up CT scans were obtained at a median of 177 days (IQR, 170-185 days) after hospital admission. Pulmonary residual abnormalities and fibrotic-like changes were found in 98 (36. 2%) and 39 (14. 4%) participants. In multivariable analysis of pulmonary residual abnormalities and fibrotic-like changes, the top three predictive factors were invasive ventilation (OR 13. 6; 95% CI 1. 9, 45; P  60 years (OR 9. 1; 95% CI 2. 3, 39; P = . 01), paxlovid (OR 0. 11; 95% CI 0. 04, 0. 48; P = . 01) and invasive ventilation (OR 10. 3; 95% CI 2. 9, 33; P = . 002), paxlovid (OR 0. 1; 95% CI 0. 03, 0. 48; P = . 01), smoker (OR 9. 9; 95% CI 2. 4, 31; P = . 01), respectively. The 6-month follow-up CT of recent COVID-19 pneumonia cases in China showed a considerable proportion of the patients with pulmonary residual abnormalities and fibrotic-like changes. Antivirals against SARS-CoV-2 like paxlovid may be beneficial for long-term regression of COVID-19 pneumonia.
