Preprints with The Lancet is part of SSRN´s First Look, a place where journals and other research experts identify content of interest prior to publication. These preprint papers are not peer-reviewed and are posted here as part of a 12-month trial. Authors have either opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet, or submitted directly via SSRN. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. These papers should not be used for clinical decision making or reporting of research to a lay audience without indicating that this is preliminary research that has not been peer-reviewed.

Abstract

Background: The 2019 novel coronavirus-infected disease (COVID-19) breakout in Wuhan of China has caused growing concerns about the consequences. Here we report the worst consequence, death cases with COVID-19, aiming to find out the main causes and risk factors.

Methods: Retrospective, single-center case series of two groups, 65 deceased patients (i.e., those not to survive, leading to death cases) and 96 surviving patients, all were confirmed with COVID-19 at Wuhan Red Cross Hospital in Wuhan from January 21st to February 14th, 2020. Epidemiological, demographic, clinical, laboratory, radiological, and treatment data were collected and analyzed.

Findings: Among 65 deceased patients, 52 (80%) of them were over 60 years old and males accounted for the majority (42 [65%]). Their most common coexisting health issues were cardiovascular (36 [60%]) and endocrine system (22 [43%]) diseases. Common symptoms at onset of their illnesses were short of breathe (65 [100%]), fever (59 [91%]), fatigue 56 [86%]), anorexia (54 [86%]) and cough (42 [65%]). By contrast, 31% of the 96 surviving patients had leukopenia, comparing toonly 8% of the deceased. The deceased patients’ average percentage of lymphocytes was higher than the surviving group’s at the time of symptoms onset (P<0.0001). The average levels of urea nitrogen, creatinine, CK and LDH were all higher in the deceased patients than the survivors ( P<0.0001 ). Infection-related biomarkers including CRP also showed a significant difference between the deceased group and the surviving group (P<0.0001). CT images showed a tendency that more deceased patients had bronchitis, bilateral pneumonia with multiple motting and ground-glass opacitylesions in the lung than those to survive ( P <0.0001 ). Comorbidities among the 65 patients not to survive included acute respiratory injury (31 [48%]), ARDS (27 [42%]), acute heart injury (3 [5%]), acute renal injury (2 [3%]) and septic shock (1 [2%]), comparing to one (1%) survivor with ARDS ( P<0.0001 ).

Interpretation: The main causes of death were acute respiratory injury and ARDS. Risk factors were ages and underlying diseases. The full spectrum of disease severity (range from asymptomatic, to symptomatic extents, requiring hospitalization or fatal), treatment and prevention require further investigations.
