Compared to healthy controls, statistically significant lower platelet count and hemoglobin concentration along with higher Mean platelet volume (MPV), Th17 cells percentage, and serum levels of IL-23 and IL-17A were detected in ITP patients (Table 1). Regarding Th17, IL-23 and IL-17A, we found no statistically significant difference in their levels in chronic ITP patients when compared with those with acute ITP (Table 2). Here, IL17A is linked to autoimmune thrombocytopenic purpura.
