Description
Summary:Objective: The aim of this study was to determine the long-term clinical, laboratory and radiologic findings, long-term follow-up findings after acute infection and complications in patients who recovered from COVID-19 infection, especially in patients with insufficient data on long-term effects.Material and Method: Patients who were admitted to the pulmonology outpatient clinic of our hospital and recovered from COVID-19 infection were included in the study. Demographic data, peripheral oxygen saturation, mMRC score, 6-minute walk test data, ongoing symptoms, laboratory data, radiologic findings and complications during follow-up were recorded. Patients admitted up to the first 4 weeks from the time of diagnosis were grouped as visit 1, patients admitted between 4 and 12 weeks were grouped as visit 2, and patients admitted after 12 weeks were grouped as visit 3.Results: A total of 520 patients were evaluated, including 190 patients at the first visit interval, 203 patients at the second visit interval and 127 patients at the third visit interval, including duplicate patients. 54% of the participants were female, 46% were male and the mean age was 54 years. Patients had at least one ongoing symptom in 96.3%, 90.6% and 89.8% of the visits, respectively. The most common symptoms were exertional dyspnea, fatigue and cough. The most common pathologic radiographic findings were ground glass opacities in the early period and linear/reticular opacities in the late period. The rates of complications during follow-up were 4.7%, 23.2%, 24.4% according to the visit intervals, respectively and the most common complication was pulmonary fibrosis.Conclusion: COVID-19 patients; while struggling with the problems associated with the acute disease in the early period, they also have to struggle with persistent symptoms and newly developing complications in the long term. In this context, we think that our study will form a basis for the data of our country and contribute to the literature.
