    Abstract

    in English, Chinese
    Objective: To explore the clinical characteristics and risk factors of patients with Coronavirus Disease 2019 (COVID-19) when developing multiple organ dysfunction syndrome (MODS). Methods: Data from 458 inpatients of confirmed COVID-19 in Wuhan, Shanghai and Tongling from December 29, 2019 to March 24, 2020 were retrospectively collected. COVID-19 was confirmed by real-time RT-PCR of throat swab samples. Data of demographics, clinical presentation, laboratory tests, imaging findings, treatment and prognosis were obtained from medical record and compared between COVID-19 patients with and without MODS. Risk factors for the development of MODS were analyzed by univariate and multivariate logistic regression analysis. Results: Of the 458 COVID-19 patients (266 from Wuhan, 208 from Shanghai, and 24 from Tongling), 103 developed transient or persistent MODS in the course. More male patients were found in those with MODS (72.8% vs 54.6%, P=0.001). And MODS patients were of older age (72.8% vs 54.6%, P=0.001), more chronic comorbidities (68.0% vs 43.4%, P<0.001), and longer onset-to-admission interval (9.0 vs 7.0 d, P<0.001). In addition, patients with MODS had more expectoration (45.6% vs 29.9%, P=0.003) and shortness of breath (52.4% vs 19.4%, P<0.001), dysfunction of various systems, decreased cellular immunity and elevated IL-6 (9.6 vs 7.6 g/L, P=0.015) in laboratory tests, isolation of other pathogens (18.4% vs 5.6%, P<0.001), and infiltration of all five lobes (75.3% vs 57.6%, P=0.003). During hospitalization, patients with MODS needed a higher proportion of comprehensive treatment and reached a mortality rate of 66.0%. Independents risk factors for development of MODS in COVID-19 patients were: onset-to-admission interval>7 days (OR=2.17, 95%CI: 1.11-4.22, P=0.023), shortness of breath (OR=3.19, 95%CI: 1.60-6.37, P=0.001), lymphocyte count<1×109/L (OR=2.67, 95%CI: 1.31-5.46, P=0.007), blood urea nitrogen>7mol/L (OR=6.27, 95%CI: 2.80-14.08, P<0.001), procalcitonin>0.1 ng/mL (OR=2.48, 95%CI: 1.20-5.13, P=0.014), and C-reactive protein>10 mg/L (OR=3.92, 95%CI: 1.41-10.89, P=0.009). Conclusions: COVID-19 patients with MODS were of higher severity and mortality. Early identification of high-risk groups with MODS according to risk factors may be helpful for early treatment.
