Background/aim: Pneumonia is the most serious clinical presentation of COVID-19. This study aimed to determine the demographic, clinical, and laboratory findings that can properly predict COVID-19 pneumonia. Materials and methods:This study was conducted in the Gazi University hospital. All hospitalized patients with confirmed and suspected SARS-CoV-2 infection between 16 March 2020 and 30 April 2020 were analyzed retrospectively. COVID-19 patients were separated into two groups, pneumonia and nonpneumonia, and then compared to determine predicting factors for COVID-19 pneumonia. Variables that had a P-value of less than 0.20 and were not correlated with each other were included in the logistic regression model. Results:Of the 247 patients included in the study 58% were female, and the median age was 40. COVID-19 was confirmed in 70.9% of these patients. Among the confirmed COVID-19 cases, 21.4% had pneumonia. In the multivariate analysis male sex (P = 0.028), hypertension (P = 0.022), and shortness of breath on hospital admission (P = 0.025) were significant factors predicting COVID-19 pneumonia. Conclusion:Shortness of breath, male sex, and hypertension were significant for predicting COVID-19 pneumonia on admission. Patients with these factors should be evaluated more carefully for diagnostic procedures, such as thorax CT.

AIM: Hyponatremia is the most common electrolyte disturbance among infections, especially with pneumonia. Here, we aimed to analyze the presence of hyponatremia among COVID-19 patients along with its relation to mortality. MATERIALS and METHODS: Patients were divided into two groups COVID-19 negative and positive and also another group with pneumonia and without pneumonia for covid-19 PCR positive patients. The association between hyponatremia and in-hospital mortality from any cause was evaluated with univariate and multivariate cox regression model. RESULTS: A total of 636 patients, a mean age of 50± 18 years, 48 % of the female with a median duration of hospitalization of 5.5 (IQR, 2,11) days were included. Of those 553 (%87) were detected COVID-19 PCR positive and 298 (47%) of those with pneumonia. The median serum sodium concentration was lower in COVID-19 PCR positive patients [134 (IQR, 130,137) mEq/L] compared to negatives [139 (IQR, 136, 140) mEq/L] (p
