In diabetic patients infected during the first and second waves, we observed that concentration of most of the evaluated cytokines/chemokines were similar to those of controls, with the exception of IP-10, IL-8 and IL-10 and of IL-8 and IL-28 that were increased in diabetic COVID-19 patients from the first and second wave, respectively, when compared to controls (Figure 4A). This evidence concerns the gene IL10 and COVID-19.
