Analysis of clinical characteristics, nucleic acid detection and prognosis of 72 cases of common type Corona Virus Disease 2019(COVID-19) pneumonia in Hubei Province,China

Abstract Background: To describe the clinical characteristics and the time of nucleic acid turning negative in patients with common type Corona Virus Disease 2019(COVID-19) pneumonia and analyze the treatment time and prognostic factors.Methods: It’s a retrospective analysis of 72 cases of common type COVID-19 pneumonia diagnosed by nucleic acid test and Computed tomography (CT).Results: The average time of nucleic acid test turning negative is 17.37±9.29 days, and the average treatment time was 23.74±8.06 days. There was no influence of Blood leukocyte count, Neutrophil count, lymphocyte count, C-reactive protein (CRP), glutamic-pyruvic transaminase (ALT), glutamic oxalacetic transaminase (AST), creatinine, D-dimer on the prognosis of the patients, whether univariate or multivariate logistic regression analysis. By χ2 test of the drugs and prognosis, we found that oseltamivir may have an impact on the prognosis of patients (P<0.05), while other drugs have no significant impact on the prognosis of patients. Through the correlation analysis, we found that age, the admission temperature, leukocyte count, neutrophil count, CRP were positively correlated with the treatment time of the patients (both P<0.05). Leukocyte count and neutrophil count were positively correlated with the time of nucleic acid test turning negative (both P<0.05).Conclusions: Age, the admission temperature, leukocyte count, neutrophil count, CRP were positively correlated with the treatment time of the patients. Leukocyte count and neutrophil count were positively correlated with the time of nucleic acid test turning negative. Oseltamivir may have an impact on the prognosis of patients, but the detailed role needs further study.
