ABSTRACT
【Objective】 To investigate the relationship between anti-platelet antibodies, therapeutic effect of intravenous immunoglobulin (IVIG) and Treg/Th17 cells imbalance in children with immune thrombocytopenia (ITP). 【Methods】 The changes and correlation of platelet count and Treg/Th17 ratio before and after IVIG treatment in 60 newly diagnosed ITP children with anti-platelet antibodies and 60 children with primary ITP without anti-platelet antibodies were analyzed. 【Results】 1) Compared with the control group, the efficacy of IVIG treatment was better in children with ITP in the case group(CR+ R cases: 50 vs 32) (P<0.01). 2) After IVIG treatment, platelet count(×109/L)(case: 4.5±2.9 vs 327.4±69.5, control: 4.1±3.2 vs 304.7±75.9), Treg cell level(%)(case: 2.15±1.08 vs 5.09±1.37, control: 2.41±0.92 vs 4.98±1.10), Treg/Th17 ratio(case: 1.10±0.19 vs 7.75±1.11, control: 1.27±0.21 vs 4.69±0.81)significantly increased while Th17 cell level(%) significantly decreased in the 2 groups of children(case: 2.07±1.31 vs 1.37±0.92, control: 2.13±1.18 vs 1.48±1.01); compared with the control group, there was no significant change in Treg, Th17 and Treg/Th17 ratio before and after treatment in the case group (P>0.05), but platelet count increased more significantly (P<0.05). 3) There were 3 positive cases in the control group and 12 negative cases in the case group after IVIG treatment, and IVIG treatment probably had no effect on the positive rate of anti-platelet antibodies in children with ITP (P>0.05). 4) The change in platelet count after IVIG treatment was significantly positively correlated with Treg levels (r=0.49 in the case group and r=0.441 in the control group) and negatively correlated with Th17 cell levels (r=-0.390 in the case group and r=-0.364 in the control group). 【Conclusion】 Anti-platelet antibodies can be used as a predictor of the efficacy of IVIG therapy in children with ITP, but they are not associated with changes in the Treg/Th17 ratio.
