摘要
Objective:To investigate the clinical symptoms of coronavirus disease 2019(COVID-19)patients with and without B.1.1.7 mutation.Methods:This retrospective observational study included COVID-19 patients who were divided into two groups,the mutation and the non-mutation group.Demographics characteristics,clinical characteristics,laboratory parameters,and mortality rates were recorded and compared between the two groups.Results:A total of 196 patients were included in the study.The relationship between the mutant virus status and sex,age,comorbidity,survival status,and disease severity was not significant(P>0.05).No significant differences were found in duration of hospitalization between the mutation and the non-mutation group(P>0.05).However,there was a statistically significant difference between patients with and without mutant viruses in hemoglobin,mean platelet volume,procalcitonin,low density lipoprotein,iron-binding capacity,potassium,calcium,C-reactive protein,folate,creatine kinase myocardial band,D-dimer,and international normalized ratio(P<0.05).Conclusions:No significant difference is found in mortality rate,disease severity or duration of hospitalization between the patients with and without variant B.1.1.7.Careful monitoring of COVID-19 patients is required for all variants.
