Abstract:
Objective To detect the serum level of interleukin (IL)-1 1, lymphocyte subsets and NK cells in patients with idiopathic thrombocytopenic purpura (ITP), and explore the related factors in the pathogenesis of ITP. Methods The serum level of IL-11, lymphocyte subsets and NK cells were detected by double antibody sandwich enzyme linked immunosorbent assay (ELISA) and flow cytometry in 50 ITP patients (ITP group) and 30 controls (control group). Results The platelet in ITP group [ (30.21 ± 19.40) ×109/L] was lower than that in control group [ (207.21 ± 31.55 ) × 109/L] obviously (P < 0.05 ); the serum level of IL-11 in ITP group [(255.72 ± 163.43) ng/L] was significantly higher than that in control group [ (40.60 ± 5.57 ) ng/L ] (P < 0.05 ). The correlation analysis indicated that the blood serum levels of IL- 11 had negative relationship with the platelet (r = -0.557 ,P < 0.05). The percentage of CD3+ and CD4+ T lymphocyte percentage, CD4+/CD8+ in ITP group were lower and the percentage of CD8+ T lymphocyte was higher than those in control group obviously (P < 0.05 ). The percentage of CD3- CD(16+56) +NK cell in ITP group was lower than that in control group (P < 0.05). Conclusion IL-11, lymphocyte subgroup and NK cell change correlate with ITP morbidity closely, and the IL-11 level and the platelet possibly have the negative feedback control action.
