ARTICLE HIGHLIGHTS
Research background

Coronavirus disease 2019 (COVID-19) has spread rapidly to multiple countries, and the illness severity, the atypical clinical presentation, and lack of specific anti-viral treatment have posed a challenge for the diagnosis and treatment of COVID-19.

Research motivation

Understanding the epidemiological and clinical characteristics of COVID-19 cases in different geographical areas are essential to improve the prognosis of COVID-19 patients.

Research objectives

This study aimed to investigate the epidemiological and clinical characteristics and main therapeutic strategy for confirmed COVID-19 patients hospitalized in Liaoning Province, China.

Research methods

A total of 65 adult patients with confirmed COVID-19 were enrolled in this retrospective study from January 20 to February 29, 2020 in Liaoning Province, China. Based on the severity of COVID-19, the patients were divided into nonsevere and severe groups.

Research results

Compared with nonsevere patients (75.4%), severe patients (24.6%) had significantly lower lymphocyte counts, elevated levels of lactate dehydrogenase and C-reactive protein, and a longer median duration of viral shedding. The overall median viral shedding time was 19.5 d, and the longest was 53 d. Severe patients were more frequently treated with lopinavir/ritonavir, antibiotics, glucocorticoid therapy, immunoglobulin, thymosin, and oxygen support.

Research conclusions

Our findings may facilitate the identification of severe cases and inform clinical treatment and quarantine decisions regarding COVID-19 patients.

Research perspectives

The identification of severe cases with COVID-19 may help prevent poor outcomes, while the estimated duration of viral shedding may help inform quarantine decisions and prevent acute respiratory syndrome coronavirus 2 spread.
