Abstract
Summary
Since early 2020, the coronavirus disease 2019 (COVID-19) pandemic has been raging on relentlessly withover540 million confirmed cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)infection and over 6,34million reported deaths as of 6July 2022.
Despite the majority of patients recovering well, a significant proportion – including mild cases – stillexperience symptoms of fatigue and exertional dyspnea with persistent absenteeism from work up to 6and even 12 months after infection.
post-viral syndromes arewell documented following other viral infections,including previous coronavirus outbreaks such as severeacute respiratory syndrome (SARS) and Middle Eastrespiratory syndrome (MERS).
This condition, defined as post-COVID-19 syndrome, is increasingly affecting a high number of people as the pandemic evolves.
The aim of the study:assessment and follow of up persistent respiratory symptoms in patients recovered from COVID-19 aiming to identify and address the clinical needs of COVID-19 survivors.
This study was performed on 71 adults patients more than 18 years old diagnosed with COVID-19 at Beni-Suef University hospital.
assessment was done including history taking, physicalexamination, measurement of peripheral oxygen saturation,spirometry and HRCT chest.
Patients were assessed at 3 months, 6 months, and 12 months after recovery.
At 3 months follow up patients were assessed for persistent symptoms, underwent spirometry. Patients under went HRCT chest if they had abnormalities at base line scan.
At 6 and 12 months, patients underwent HRCT and spirometry if they had still symptoms or detectable abnormalities at the last assessment.
the most common persistent symptom in 3rd month of follow-up was dyspnea followed by fatigue then cough. In the 6th month, dyspnea and fatigue persisted in 33.8% and 22.5 % of cases respectively while at the 12th-month dyspnea and fatigue persisted in 22.5% of cases and 11.3% of cases respectively.
At 3 months follow up out of 59 patients, 19 patients had GGO and 13 patients had fibrotic changes.at 6 months follow up out of 32 patients,2 patients had GGO and 16 patients had fibrotic changes. At 12months follow up ,16 patients still had fibrotic changes.
among patients with abnormal spirometry test at 3 months of diagnosis of COVID, there was no significant improvement in spirometry test between 3 months, 6 months, and 12 months.
