Abstract:

Objective To investigate the roles of inflammatory indicators and cytokines in the occurrence and development of corona virus disease 2019(COVID-19). Methods From January to February 2020,328 patients with COVID-19 in Shanghai Public Health Clinical Center were classified into 2 groups according to disease severity,including light/common group and severe/critical group. By retrospective analysis,the laboratory determination data of inflammatory indicators and cytokines,such as C-reactive protein(CRP),erythrocyte sedimentation rate(ESR),high-sensitivity C-reactive protein(hs-CRP),heparin-binding protein(HBP),lactate dehydrogenase(LDH),procalcitonin(PCT),white blood cell(WBC) count,lymphocyte(LPC) count,interleukin(IL)-1β,IL-2,IL-4,IL-5,IL-6,IL-8,IL-10,IL-12P70,IL-17,tumor necrosis factor alpha(TNF-α),interferon alpha(IFN-α) and interferon gamma(INF-γ),were collected. Results Compared with light/common group,severe/critical group had a higher age [68.5(11.5) years old,P<0.01],longer hospitalization time [21(10) d,P<0.01] and lower discharge rate(32.14%,P<0.01). Compared with light/common group,in severe/critical group,the levels of CRP[55(84.5) mg/L,P<0.01],hs-CRP[43.58(76.46) mg/L,P<0.01],HBP[61.37(111.01) ng/mL,P<0.01],LDH[354.5(150.5) U/L,P<0.01],PCT[0.09(0.21) mg/L,P<0.01],IL-5[0.49(1.6) pg/mL,P=0.01],IL-6[10.78(56.24) pg/mL,P<0.01],IL-8[12.97(19.4) pg/mL,P<0.01] and IL-10[0.82(1.94) pg/mL,P=0.03] were increased,and LPC count [0.77(0.5)×109/L,P<0.01],IL-4[0(0) pg/mL,P<0.01] and IL-17[0(0) pg/mL,P=0.01] were decreased. ConclusionsInflammatory indicators and cytokines between light/common group and severe/critical group among COVID-19 patients have obvious difference. The levels of CRP,HBP,hs-CRP and PCT indicate the development of COVID-19 to severe situation. The determinations of LPC,IL-4,IL-6,IL-8 and IL-10 levels play roles in predicting the clinical progression,especially the occurrence of inflammatory storm.
