Concerning the extended lymphocyte phenotyping, the findings from this study are in line with data deriving from a study by Montin et al., in which patients affected by ITP and/or autoimmune hemolytic anemia showed reduced levels of CD4+ naïve cells, RTEs, and switched memory B cells compared to patients without hematologic autoimmunity [26]. This evidence concerns the gene CD4 and autoimmune thrombocytopenic purpura.
