Secretory Imbalance between Pro-inflammatory and Anti-inflammatory Cytokines in the Patients with Immune Thrombocytopenia / 中国实验血液学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the imbalance of pro-inflammatory and anti-inflammatory cytokines in the patients of immune thrombocytopenia (ITP).</p><p><b>METHODS</b>Thirty-five patients with ITP were enrolled in ITP group, while 28 healthy persons were included in control group. The expressions of IL-8, IL-17A, IL-22, TNF-α, IFN-γ, IL-4, CD40, CD40L, TGF-β and IL-10 were detected by flow cytometry with aimPlex multiple immunoassay Flow.</p><p><b>RESULTS</b>The expressions of pro-inflammatory factors IL-8, IL-17A, IL-22, IFN-γ and TNF-α in ITP group all were significantly higher than that in the control group (P<0.05), however the expressions of anti-inflammatory factors IL-4, CD40L, TGF-β and IL-10 in ITP group all were significantly lower than that in the control group (P<0.05). The expression of CD40 was not significantly different between ITP group and control group (P>0.05). Expressions of TNF-α significantly related with platelet counts in both ITP group and control group (ITP group, r=0.64, P<0.05; control group, r=-0.41, P<0.05). However the expression of CD40, TGF-β, CD40L, IL-8, IL-17A, IL-22, IL-10, IL-1β, IFN-γ and IL-4 significantly did not relate with platelet counts in both ITP and control group.</p><p><b>CONCLUSIONS</b>The secretory imbalance between pro-inflammatory and anti-inflammatory cytokines exists in the patients of ITP. The decrease of Plt regulated may be regulated by the abnormal expression of TNF-α.</p>
