ABSTRACT

Objective: The aim of this study is to show the consistence between the recommended guidelines regarding the triad of symptoms-cough, dyspnea, and fever-and the diagnosis of COVID-19. Methods: A prospective observational study conducted at a tertiary emergency department between April 2, 2020 and May 15, 2020 in Turkey. Detailed patient history, main presenting complaints and imaging findings were recorded. For COVID-19 confirmation, nasopharyngeal RT-PCR was used. The relationship between complaints and COVID-19 test results were analyzed. Results: Of the 1226, suspected COVID-19 patients, 127 were positive, 471 were negative, and 628 were discharged without any tests. The most common presenting complaints of the COVID-19 positive patients were throat pain (25.2%), dyspnea (15%), cough (22%), malaise and fatigue (11.8%), and fever (8.7%). There was no statistically significant difference between the positive and negative test groups as they had fever (chi(2), p = 0.30), cough (chi(2), p = 0.67) and dyspnea (chi(2), p = 0.14). Conclusion: Considering that it is difficult to diagnose COVID-19 in emergency settings, testing decision and diagnosis should not depend only on classical symptoms;otherwise, patients with atypical and rare symptoms may be missed. Instead, patient history, clinical status, and radiological findings should be considered together.

ABSTRACT

Objective: The aim of the study is to compare the differences between COVID-19 pneumonia and other viral pneumonia (OVP) in terms of demographic, clinical and radiological features. Methods: This retrospective cohort study was conducted in Gazi University Hospital between 11 March and 24 May 2020. Patients, admitted to the hospital with suspected COVID-19 infection aged >18 years and those who had pneumonia on chest computed tomography (CT) scan were evaluated. SARS-CoV-2 RT-PCR and multiplex PCR, for other respiratory viruses, were performed. Patients with a positive SARS-CoV-2 PCR were included in "COVID-19 pneumonia" group and those who had a positive result for any other respiratory viruses and two consecutive negative results for SARS-CoV-2 were included in the "OVP" group. Two groups were compared in terms of clinical, laboratory and chest CT findings. Results: Of the 63 patients included in the study, 45 had COVID-19 pneumonia and 18 had OVP. Cough, nasal congestion, sputum production and leukocytosis were more common in the OVP group while leukopenia was more common in the COVID-19 pneumonia (p<0.05). The distribution pattern of parenchymal lesions on chest CT was more likely to be predominantly peripheral and posterior in COVID-19 pneumonia compared to OVP. Bilateral involvement was also more frequent in COVID-19 group compared to OVP (p<0.05). Conclusion: Distinguishing COVID-19 pneumonia from OVP with clinical and laboratory findings is difficult. Chest CT findings such as peripheral and posterior distribution of the parenchymal lesions and bilateral involvement may help to differentiate COVID-19 pneumonia from OVP.
