Background The 2019 novel coronavirus (SARS-CoV-2) has caused an outbreak in the world. The critically ill patients had a high mortality. However, the possible risk factors of critical patients with coronavirus disease 2019 (COVID-19) are not fully known. We aim to investigate the risk factors in critical patients with COVID-19 and to address their role in predicting disease progression.
Methods In this single-centered, retrospective, observational study, we enrolled 91 critically ill adult patients with COVID-19 in Renmin Hospital of Wuhan University between Jan 20, 2020 and Feb 28, 2020. Data were collected using a standard method including clinical records and laboratory findings.
Results 39 patients (42.9%) were dead and 52 patients (57.1%) were cured and discharged before Mar 22, 2020. CD4 T cell count, CD8 T cell count and glomerular filtration rate were significantly lower in non-survivors than in survivors. However, the non-survivors presented a higher proportion of D-dimer, Cardiac troponin and immunoglobulin G than in survivors. Intravenous immunoglobulin was more common in survivors than in non-survivors. On multivariate analysis, D-dimer (༞1 µg/mL, OR = 9.53, 95% CI, 2.53–35.88), CD4 + T count (༜200/µl, OR = 9.68, 95%CI, 2.76-40.00 ) and cardiac troponin (༞0.04 ng/mL, OR = 5.73, 95% CI, 1.86–17.66) were independent risk factors for mortality.
Conclusion The decrease of CD4 T cell is associated with higher risk mortality in critical inpatients with COVID-19. Intravenous immunoglobulin was more common in survivors than in non-survivors.
