Clinical analysis of the effect of thymalfasin on common type patients with COVID-19

ABSTRACT

Objective We observed the effect of thymalfasin on common type patients with COVID-19. Methods A total of 26 cases of common type COVID-19 patients with had reduced cellular immune function (CD4+T counts<410 cells/L) in the Public and Health Clinical Center of Chengdu and discharged from January 29, 2020 to March 20, 2020 were included as research objects, and they were divided into control group and observation group, depending on whether or not the thymalfasin method is used. The patients in control group used recombinant human interferon a-2beta, abidor or lopinavir/ritonavir, and traditional Chinese medicine, the observation group extra added thymalfasin. Then the treatment effect were compared between the two groups. Results There were no significant difference in age, gender, condition and the baseline CD4+T and CD8+T counts between the two groups, the cases were all followed up at our hospital after discharge. There was no significant difference in time of SARS-CoV-2 nucleic acid turning negative, hospital stay, nucleic acid re-positive rate, C-reactive protein and serum amyloid protein (SAA) at discharge between the two groups (P > 0.05). The CD4+T count and CD8+T count at discharge in two groups were both higher than those on admission (P < 0.05), there were no statistical significances in the degree of elevation between the two groups(P > 0.05). Conclusion The study does not show that common type COVID-19 patients who had reduced cellular immune function can obtain definite clinical benefits by using the thymalfasin according to the instructions.
