ABSTRACT
OBJECTIVE: Data about Turkish coronavirus disease 2019 patients are limited. We evaluated hospitalized coronavirus disease 2019 patients who were followed up in the first 3 months of the pandemic. MATERIAL AND METHODS: This retrospective, single-center, observational study included 415 confirmed hospitalized coronavirus disease 2019 patients. The patients were divided into groups, namely, mild, moderate, and critically ill patients. Symptoms at the time of admission, clinical, laboratory, and imaging findings were examined. RESULTS: In our study, 6.74% of coronavirus disease 2019 patients had severe disease, 59.5% were male, and the mortality rate was 11.3%. Diabetes mellitus and chronic obstructive pulmonary disease were more frequently seen in critically ill patient groups and hypertension in moderate patient groups. Anemia and aspartate aminotransferase levels were higher in non-survivors among mild coronavirus disease 2019 patients. In the moderate patients' group, aspartate aminotransferase, lactate dehydrogenase, international normalized ratio, ferritin, and D-dimer levels were higher and lymphocyte, hemoglobin levels were lower; in the critically ill patients' group, platelets were lower and uric acid levels were higher in non-survivor patients. CONCLUSION: In mild patients, anemia, lymphopenia, and increased aspartate aminotransferase levels; in moderate patients, leukopenia, anemia, and increased aspartate aminotransferase, lactate dehydrogenase, international normalized ratio, ferritin, and D-dimer levels; in the critically ill patient group, lower platelet and increased uric acid levels should be followed closely as they are mortality predictors.
