A summary of the article is shown below:
High-dose dexamethasone (HD-DXM) is debated as a second-line therapy for chronic Immune thrombocytopenia (ITP) in children. The aim of this study is to evaluate the efficacy and safety of HD-DXM as an emergency therapy in uncontrolled bleeding in children with chronic ITP and to assess its immunological effect on dendritic cells (DCs) percentage and their co-stimulatory markers CD86 and CD83. Totally, 20 children previously diagnosed as chronic ITP were enrolled in this study and all admitted to hospital with uncontrolled bleeding. Patients received HD-DXM as a single daily dose for 4 days. Blood samples were withdrawn from patients just prior to HD-DXM therapy and on day 5 to evaluate the platelet count and for flowcytometric analysis of DCs. Daily assessment of bleeding severity was performed. The platelet counts significantly increased in patients after 5 days of initiation of therapy compared with platelet count before therapy (p-value = 0. 0002). Control of bleeding observed in (90%), complete response (CR) documented in (50%), response (R) documented in (40%), and no response (NR) documented in (10%) of patients. The time to respond was raging from 1 to 3 days and minor complication recorded in two patients. Both plasmacytoid DCs and myeloid DCs percentage and their expression of co-stimulatory markers, CD86 and CD83 decreased significantly after HD-DXM therapy. Conclusion: short course of HD-DXM as a rescue therapy seems to be an effective alternative emergency treatment for uncontrolled bleeding in chronic ITP children especially in nations with limited resources.
