RESUMO
Objective:To explore the efficacy of gamma globulin at different doses combined with dexamethasone in the treatment of children with severe idiopathic thrombocytopenic purpura. Methods: Totally 96 cases of patients with idiopathic thrombocytopenic purpura were divided into group A ( standard high dose of gamma globulin+dexamethasone) , group B ( middle dose of gamma globulin+dexamethasone) and the control group ( dexamethasone) . The clinical effects and platelet parameters of the three groups were com-pared. Results:The levels of PLT, PCT and PDW in group A and group B after the treatment were higher than those in the control group(P0. 05). The clinical effective rate of group A and group B was higher than that in the control group(P0.05). There was no significant difference in the incidence of adverse reactions among the three groups (P>0. 05). Conclusion:Gamma globulin at middle dose shows significant effect as at high dose in the patients with ITP, which can reduce the dosage and is worthy of clinical promotion.
