M-MDSC may be related to the disorder of immune tolerance in the patients with ITP, and may become a new index to monitor the curative efficacy of ITP patients. M-MDSC may be related to the disorder of immune tolerance in the patients with ITP, and may become a new index to monitor the curative efficacy of ITP patients. To investigate the factors affecting the chronicity of childhood primary immune thrombo-cytopenia (ITP) and compare the efficiency of different first-line treatment regimens. Children with ITP hospitalized in our hospital from September 2013 to October 2018 were retrospectively analyzed. Three hundred and one children (150 males and 151 females) were included in this study, with a median age of 8 (0.17-17) years old, and 110 (36.5%), 92 (30.6%), and 99 (32.9%) cases were grouped into newly diagnosed, persistent, and chronic ITP, respectively. The median of follow-up was 41.92 (1.07-74.03) months. At the end of the follow-up (October 2019), among the 202 newly diagnosed/persistent ITP children, 79 cases (59 newly diagnosed and 20 persistent ITP) achieved remission within 1 year after initial diagnosis, with a remission rate of 39.3%; 122 cases (50 newly diagnosed and 72 persistent ITP) developed chronic disease, with a chronicity rate of 60.7%; one case underwent splenectomy. In 99 cases with chronic ITP that of steroid alone. Insidious onset of symptoms in pediatric ITP increases the risk of chronicity, while the positive titer of anti-platelet membrane glycoprotein may reduce the risk. In the first-line treatment for the newly diagnosed/persistent children. The efficacy of IVIG alone or combined with steroid is better than that of steroid alone. To investigate the damaging of human umbilical vein endothelial cells (HUVEC) induced by antiplatelet integrin β3 antibodies in vitro. T
