Objective To explore the clinical features of critical cases of coronavirus disease 2019 (COVID-19). Methods The clinical data of nine patients who were diagnosed with critical COVID-19 in Hainan General Hospital from January 21, 2020 to February 6, 2020 were retrospectively analyzed. RT-PCR testing for 2019 novel coronavirus (2019-nCoV) was performed with multi-sites synchronize specimens including pharyngeal swab, blood, excrement, and urine. The serum levels of leucocyte, C-reactive protein, procalcitonin and lactic acid between the improved group (five cases) and the deteriorated group (four cases) were compared. The t test was used for comparison of normally distributed continuous data between groups. Results There were eight males (88.9%) and 1 female enrolled. The patients aged 28-77 years old, with an age of (52.9±18.0) years. By March 4, 2020, all five cases in improved group were cured and discharged, three cases in deteriorated group died and 1case remained in critical condition. All multi-sites specimens of patients in improved group turned negative in 2-4 weeks of illness onset, while those of cases in deteriorated group showed sustained viral nucleic acid positive (up to 48th day of illness onset). The white blood cell counts ((13.52±8.24)×10 9 /L vs (10.49±4.46) ×10 9 /L), C-reactive protein ((139.71±87.46) mg/L vs (78.60±55.40) mg/L) and procalcitonin ((2.32±4.03) ng/mL vs (0.28±0.58) ng/mL) , lactic acid ((3.70±4.14) mmol/L vs (2.33±0.53) mmol/L) in deteriorated group were all significantly higher than those in improved group ( t =2.908, 5.009, 4.391 and 2.942, respectively, all P <0.01). A rapid rise of serum IL-6 level up to 8 500 pg/mL was observed in one patient three days prior to death. Conclusion Among the patients with critical COVID-19, serum levels of inflammatory cytokines of the death cases are higher than those of improved and discharged cases.
