Analysis of 239 ordinary and severe cases of COVID-19: Clinical features and treatment

Abstract

This study retrospectively analyzed the clinical characteristics of patients with new coronavirus infection (COVID-19) and summarizes the treatment experience. A total of 239 COVID-19 patients admitted to the Hajar Hospital, Aja University of Medical Science, Tehran, Iran from March 22, 2020 to May 18, 2020 were selected, including 176 cases in the ordinary group and 63 cases in the severe/critical group. We collected and compared the clinical data of the two groups of patients, including general conditions, clinical symptoms, signs, laboratory tests, lung CT imaging and prognosis, and analyzed the treatment plans of the two groups. The mean age of 239 COVID-19 patients was 48.1±17.6 years, including 132 males. Patients in the severe and critically ill groups were older than the normal group, with more males and more underlying diseases. The difference was statistically significant (p < 0.05). The lymphocyte (LYM) counts and albumin (ALB) counts of the severe and critically ill groups were more significantly lower than those of the normal group; while the percentage of neutrophils (NEU), C-reactive protein (CRP), D-dimer, and lactate The increase of lactate dehydrogenase (LDH) and urea nitrogen (BUN) was more significant, and the difference was statistically significant (p < 0.05). Patients in the severe and critically ill groups received more antiviral drugs, glucocorticoids, and nasal catheters than those in the normal group, and the difference was statistically significant (p < 0.05). Also, we observed that the most radiological finding was bilateral ground-glass opacity in both groups, however, the rate of typical abnormalities in both chest CT scan and chest x-ray was significantly higher in sever/critical group except air-bronchogram. Taken together, we showed that combination of oseltamivir and glucocorticosteroid such as dexamethasone was very effective in severe patients.
