Abstract

Background: Infection with viral agents causes upregulation of cytokines such as Tumor Necrosis Factor-alpha (TNF-α), which is considered an important mediator of inflammation. TNF-α has been associated with a poor prognosis in patients with the severe acute respiratory syndrome (SARS). Patients and methods: This study included 66 mild COVID-19 patients with confirmed COVID-19 infection and 22 healthy people as a control group, these study subjects were randomly selected irrespective of the age group and both genders were included, 1 ml blood sample was collected for performing serum TNF-α levels test, Reagents of EIAab is located at East Lake Hi-Tech Development Zone, Wuhan China.  Human tumor necrosis factor ELISA kit TNF-α serum levels immunoassay test catalog number E0133h. Results: This study reveals that serum TNF-α levels for mild COVID-19 patients and healthy control people were non-significant with a p-value of 0.1191 between the two groups. Conclusion: the serum TNF-α level is not a significant biomarker for diagnosis or prognosis of mild COVID-19 patients (Outpatients and patients under home observation), while other studies reported patients with COVID-19 demonstrated significantly elevated levels of TNF- 𝛼 upon admission to hospitals.

Abstract

COVID-19 pandemic disease has firstly occurred in Wuhan, Hubei, China. Then the infection spread globally. Many researchers now suggest the strong similarities of COVID-19 with the previous pathogenic human beta coronaviruses SARS-CoV and MERS-CoV. But there is limited knowledge about the immune response to COVID-19. So on the basis of the immune response of these viruses, we will try to predict how the immune system can deal with this infection. In this review, we focus on human coronavirus types and discuss current knowledge of immune response against SARS-CoV and MERS-CoV immune response, which may be helpful in offering the perspectives on immune responses against COVID-19.
