Abstract

Introduction: The rapid worldwide spread, in addition to the morbidity and mortality associated with the novel coronavirus disease 2019 (COVID-19), have raised concern throughout the world. Identifying the characteristics of patients who died of COVID-19 is essential to implement preventive measures. Objective: We aimed at investigating these characteristics among the Iranian population in Tabriz. Methods: In this case series, we analyzed clinical characteristics, laboratory parameters, and imaging findings of 111 patients with a reverse transcriptase-polymerase chain reaction (RT-PCR)-confirmed COVID-19 diagnosis who died during hospitalization. The studied patients had been admitted to the hospital between February 2020 and May 2020. Results: The median age of patients was 73 years (IQR, 62-82 years) and approximately 70% of them were male. The median oxygen saturation on admission was 88% (IQR, 80-92%) and dyspnea, cough, and fever were the most common presenting symptoms. Among comorbidities, diabetes, hypertension, and cardiovascular diseases were more frequently observed among patients who had a fatal outcome. While ground-glass opacity was the most commonly reported finding on chest computed tomography, 5% of the patients had no abnormal finding on imaging. Chloroquine was the most frequently used medication for treatment. Conclusion: Our results showed that the majority of COVID-19 deaths occurred in male elderly with decreased levels of oxygen saturation and elevated levels of lactate dehydrogenase and erythrocyte sedimentation rate on admission. © 2021 Tehran University of Medical Sciences.
