Abstract:
Objective:To analyze the clinical and laboratory features of patients with Coronavirus Disease 2019(COVID-19), for providing reference for the diagnosis and treatment of the disease.Methods:The clinical data of 72 patients confirmed as COVID-19 in Qishan hospital during January 23, 2020 to February 13, 2020 were collected. The data included the general information, clinical manifestations, laboratory tests and CT findings of the lungs. According to the severity of the disease, the patients were divided into the non-severe group and the severe group, and the laboratory tests characteristics of the two groups were compared. SPSS 22.0 statistical software was used for data analysis.Results:In the 72 patients, 40 were males and 32 females, the average age was (46.0±14.8) years. The main clinical manifestations were fever (84.7%) and cough (77.8%). Among them, 45 cases (62.5%) had expectoration with a small amount of white sticky sputum. The main laboratory results showed that lymphocyte count decreased in 26 cases (36.1%), the absolute number of T lymphocytes decreased in 18 cases (25.0%), CD4 + T cell count decreased in 8 cases (11.1%), CD8 + T cell count decreased in 14 cases (19.4%), ESR increased in 42 cases (58.3%), and CRP increased in 31 cases (43.1%). Peripheral blood lymphocyte (L), albumin, CD4 + T cell, CD8 + T cell, T-lymphocyte in severe group (n=61) were lower than those in non-severe group (n=11), while C-reactive protein (CRP), serum amyloid A (SAA), erythrocyte sedimentation rate (ESR), fibrin (FIB), aspartate aminotransferase (AST), creatine kinase (CK), lactate dehydrogenase (LDH) in severe group were higher than those in non-severe group ( P<0.05). In 72 patients, the negative time of the twice nucleic acid detection from nasopharyngeal swabs and sputum specimens were (21.48±7.9) days and (27.79±7.4) days, there were significant differences between the two groups of specimens for two consecutive negative times ( t=-4.532, P=0.000). The main pulmonary imaging manifestations of COVID-19 patients: two lungs in 58 cases, patchy opacities in 51 cases and ground glass shadows in 61 cases. Conclusions:Most of the COVID-19 patients in Yantai and Weihai were common type. The abnormal T lymphocyte, subcohorte and other laboratory indicators may indicate that the patients are more serious.
