Background: Novel coronavirus pneumonia is a novel kind of highly contagious disease without any specific drugs. Considering the successful experience of antiviral therapy combined with glucocorticoids (GCs) in severe acute respiratory syndrome, this study was designed to evaluate the clinical efficacy of GCs in treating patients with coronavirus disease 2019 (COVID-19).Methods: A cohort of 42 patients with COVID-19 admitted to The First Hospital of Jiaxing from January 4, 2020, to February 16, 2020, were included and grouped into a test group (n=20) and control group (n=22) based on their therapeutic regimens. There were no significant differences in baseline characteristics between patients in the two groups. Conventional treatment (antiviral therapy) was given to patients in both groups, while an additional hormone drug (GCs) was used in patients in the test group. Indices including body temperature, blood routine indices [white blood cell (WBC), lymphocyte, monocyte, and C-reactive protein (CRP)], blood biochemical indices [alanine aminotransferase (ALT) and aspartate aminotransferase (AST)], and complications were recorded during the treatment. Time to achieve negative virus nucleic acid (nCoV-RNA) testing, and hospital stays were also observed and compared between the two groups.Results: All included patients completed the trial. After treatment, superior therapeutic efficacy was achieved in patients in the test group, with body temperature dropping more significantly with a much shorter recovery time compared to the control group (P=0.0412). Simultaneously, the percentage of patients with abnormal blood routine indices (WBC), monocyte, and (CRP) in the test group was reduced more sharply, while no noticeable difference was observed in the number of patients who developed abnormal blood biochemical indices during treatment between the two groups. Additionally, a shorter duration of hospital stays was found in the test group relative to the control group (14.84±8.76 vs. 18.25±7.42 days, P>0.05). Patients who received GCs had a shorter recovery time for body temperature and inflammation.Conclusions: Hormonotherapy with GCs can accelerate the recovery time for body temperature as well as inflammation in patients with COVID-19. It deserves promotion and application in the clinical treatment of coronavirus disease as a form of adjuvant medicine. The ongoing focus of research is on long-term adverse events in GCs.
