ABSTRACT
Objective:
To describe the clinical manifestations and outcomes of COVID-19, and explore the risk factors of deterioration and death of the disease.Methods:
In this retrospective study, we collected data from 121 COVID-19 cases confirmed by RT-PCR and next-generation sequencing in Renmin Hospital of Wuhan University from January 30, 2019, to March 23, 2020, and conducted statistical analysis.Results:
A total of 121 patients were included in our study, the median age was 65 years (IQR, 55.0-71.5 years), and 54.5% cases were men. Among those cases, 52 (43.0%) cases progressed to severe, and 14 (11.6%) died. Overall, the most common manifestations were fever (78.5%) and respiratory symptoms (77.7%), while neurological symptoms were found in only 9.9% of the patients. 70.2% of all the cases had comorbidities, including hypertension (40.5%) and diabetes (20.7%). On admission, cases usually show elevated levels of neutrophils (27.3%), D-dimer (72.6%), Interleukin-6 (35.2%), Interleukin-10 (64.4%), high-sensitivity C-reactive protein (82.6%), and lactate dehydrogenase (62.0%), and decreased levels of lymphocytes (66.9%), CD3 cells (67.2%), and CD4 cells (63.0%). The proportional hazard Cox models showed that the risk factors for severity progression and death included comorbidities (HR 4.53, 95% CI 1.78-11.55 and HR 7.81, 95% CI 1.02-59.86), leukocytosis (HR 1.13; 95% CI 1.05-1.22 and HR 1.25, 95% CI 1.10-1.42), neutrophilia (HR 1.15, 95% CI 1.07-1.13 and HR 1.28, 95% CI 1.13-1.46, and elevated LDH (HR 1.14, 95% CI 1.12-1.15 and HR 1.11, 95% CI 1.10-1.12). Elevated D-dimer (HR 1.02, 95% CI 1.01-1.03), IL-6 (HR 1.01, 95% CI 1.00-1.02) and IL-10 levels (HR 1.04, 95% CI 1.01-1.07) were also risk factors for the progression of disease severity. Meanwhile, lymphopenia and wake immune responses [e.g., lower CD3, CD4, or CD19 counts (all HR < 1)] were associated with disease deterioration and death.Conclusions:
Severe cases and death of COVID-19 are associated with older age, comorbidities, organ dysfunction, lymphopenia, high cytokines, and weak immune responses.
