Abstract
Background: Since December 2019, an outbreak of coronavirus disease 2019 (COVID-19) began in Wuhan and rapidly spread globally. The speed and scope of the spread of COVID-19 makes it urgent to define clinical characteristics, serological and radiological changes of the affected patients.
Methods: Seven patients with laboratory-confirmed COVID-19 who were admitted to the Third Affiliated Hospital of Sun Yat-Sen University Yuedong Hospital from January 2020 to March 2020 were retrospectively enrolled and their clinical features, serological and radiological longitudinal changes were analyzed.
Results: Among the 7 patients, all (100%) had a clear epidemiological history. The most common symptoms were respiratory symptoms 6 (85.7%), and only 2 (28.6%) of the patients had fever at their first visit. The cohort included 4 (57.1%) common types and 3 (42.9%) severe types. Two (28.6%) common type patients developed to severe type in a short time. All of the 7 patients (100%) had abnormal liver function, normal renal function, and normal procalcitonin. The detection time of specific antibody in 7 patients was 5 - 13 days after symptoms. Before the specific antibody could be detected, the absolute value of lymphocytes decreased in 2 (28.6%) common type cases transferred to severe type cases accompanied with obvious progress in pulmonary imaging. The phenomenon of decreased albumin and elevated globulin occurred in 6 patients (85.7%). The predominant pattern of lung lesions observed was bilateral (71.4%) and mainly near the pleura at the first diagnosis. Bilateral pulmonary involvement occurred in 6 cases (85.7%) during the course of disease. In 4 cases (57.1%) with obvious pulmonary lesions, the absolute value of lymphocytes decreased, albumin decreased, and globulin increased during the course of the disease.
Conclusions: Serum specific antibodies can be detected within 2 weeks of onset. Close observation of the dynamic changes of absolute value of blood lymphocytes, serum albumin, and globulin which were related to pulmonary imaging changes in patients will contribute to assessment of COVID-19.
