Objective

To identify predictors of pulmonary fibrosis development by combining follow-up thin-section CT findings and clinical features in patients discharged after treatment for COVID-19.

Materials and Methods

This retrospective study involved 32 confirmed COVID-19 patients who were divided into two groups according to the evidence of fibrosis on their latest follow-up CT imaging. Clinical data and CT imaging features of all the patients in different stages were collected and analyzed for comparison.

Results

The latest follow-up CT imaging showed fibrosis in 14 patients (male, 12; female, 2) and no fibrosis in 18 patients (male, 10; female, 8). Compared with the non-fibrosis group, the fibrosis group was older (median age: 54.0 years vs. 37.0 years, p= 0.008), and the median levels of C-reactive protein (53.4 mg/L vs. 10.0 mg/L, p= 0.002) and interleukin-6 (79.7 pg/L vs. 11.2 pg/L, p= 0.04) were also higher.
