Abstract
Abstract Background Progressive fibrotic lung disease is one of the possible consequences of COVID-19 pulmonary pneumonia, and it is one of the most worrying long-term complications. Pulmonary fibrosis is associated with non-reversible lung dysfunction. The long-term lung changes of previous COVID-19 infection still not completely understood and should be included in further studies. The aim of this study is the early detection and prediction of patients whom may develop such serious complication, thus giving a chance for early introduction of anti-fibrotic drugs. Results From April 2020 to December 2020, 80 patients in Cairo, Egypt, who have clinical manifestations and confirmed COVID-19 by PCR, were evaluated by follow-up MDCT. CT image analysis was processed including comparative study using follow-up data (different radiological signs and residual fibrotic changes). Although there was no specific cause for post-COVID-19 lung fibrosis, there were some predicting factors such as old age, cigarette smoking, high CT severity score, and long-term mechanical ventilation. Conclusion Early detection of potential cases of post-COVID-19 pulmonary fibrosis may give a chance to prevent or at least modify such disabling complication.
