Abstract:
ObjectiveTo investigate the change of the platelet function in children with primary immune thrombocy-topenia (ITP) before and after treatment.MethodsThe platelet indices, immature platelet fraction (IPF%), immature platelet counts (IPC), granule membrane glycoproteins of platelet (CD62p, PAC-1, CD42b) were tested by automatic blood cell analyzer and lfow cytometry (FCM) in 18 children with ITP before treatment and after complete response and in 17 children undergoing elective surgery (control gourp).ResultsCompared with control group, MPV, PDW, P-LCR and IPF% were signiifcantly higher and PLT, PCT, IPC were signiifcantly lower in children with ITP. The expressions of three platelet membrane glycoproteins (PAC-1, CD62p, CD42b) were signiifcantly lower in children with ITP. After treatment, children with ITP achieved completely response. Compared with before treatment, MPV, PDW, P-LCR and IPF% were signiifcantly lower, and PLT, PCT, IPC, and the expressions of three platelet membrane glycoproteins (PAC-1, CD62p and CD42b) were significantly higher. ConclusionsThe platelet function is depressed and in status of low activity in children with ITP. The relative platelet indices provide new references for the diagnosis and the judgment of therapeutic effect in ITP patients.
