“…Adults over the age of 63 had approximately three times the probability of developing abnormalities on CT scans at 12 months (35) . Furthermore, fibrotic changes appear to be more common in patients requiring intensive care unit (ICU) recovery, staying in the hospital for longer periods of time, and/or having a higher inflammatory load 36 , 37 . Six-month follow-up CTs revealed the presence of fibrosis in the same zones affected by the initial infection phase abnormalities (37) .…”

It could be linked to a reduction in cell-mediated immunity and the augmented humoral immune response in the affected zone (38) .…”

“…A few studies have examined the relationship between pulmonary abnormalities on CT and pulmonary function tests (PFTs) in patients with rPCC. [6][7][8][9][10][11] A meta-analysis with a large patient cohort reported that CT abnormalities and impaired PFTs are common in hospitalized COVID-19 patients 1 year after recovery, suggesting that rPCC may result from residual CT abnormalities. 10 Bellan et al 11 showed that the visual extent of pulmonary abnormalities on chest CT is related to rPCC.…”

Objective The aims of this study were to assess the chest computed tomography (CT) findings in post–COVID-19 respiratory condition (rPCC) patients and compare the findings with asymptomatic participants (APs). It also aimed to evaluate the relationship between CT findings and pulmonary function tests (PFTs) in rPCC patients. Finally, it aimed to compare the quantitative chest CT findings and PFT results of patients with rPCC and APs. Methods We retrospectively enrolled consecutive patients with rPCC who underwent unenhanced chest CT and PFTs between June 2020 and September 2022. In addition, a control group (APs) was prospectively formed and underwent nonenhanced chest CT and PFTs. The presence and extent of abnormalities in unenhanced chest CT images were evaluated qualitatively and semiquantitatively in a blinded manner. We used fully automatic software for automatic lung and airway segmentation and quantitative analyses. Results Sixty-three patients with rPCC and 23 APs were investigated. Reticulation/interstitial thickening and extent of parenchymal abnormalities on CT were significantly greater in the rPCC group than in the control group (P = 0.001 and P = 0.004, respectively). Computed tomography extent score was significantly related to length of hospital stay, age, and intensive care unit stay (all Ps ≤ 0.006). The rPCC group also had a lower 85th percentile attenuation lung volume (P = 0.037). The extent of parenchymal abnormalities was significantly correlated with carbon monoxide diffusing capacity (r = −0.406, P = 0.001), forced vital capacity (FVC) (r = −0.342, P = 0.002), and forced expiratory volume in 1 second/FVC (r = 0.427, P < 0.001) values. Pulmonary function tests revealed significantly lower carbon monoxide diffusing capacity (P < 0.001), FVC (P = 0.036), and total lung capacity (P < 0.001) values in the rPCC group. Conclusions The rPCC is characterized by impaired PFTs, a greater extent of lung abnormalities on CT, and decreased 85th percentile attenuation lung volume. Advanced age, intensive care unit admission history, and extended hospital stay are risk factors for chest CT abnormalities.
