The effects of B-cell depletion with rituximab on regulatory T cells (Tregs) have not been determined. We investigated Tregs in patients receiving rituximab for chronic idiopathic thrombocytopenic purpura (ITP). The peripheral blood Tregs, identified as CD4+FOXP3+ T cells, were measured by flow cytometry prior to and after the immunotherapy. In addition, Tregs were analyzed for their usage of t...

Background: Previous studies about the relationship between bone marrow megakaryocyte count and the chronicity of ITP has yielded paradoxical results. The aim of the present study was to investigate any relationship between the megakaryocyte count in the bone marrow and the chronicity of ITP. Materials and Methods: This study was performed to compare the primary bone marrow aspiration megakar...

Spontaneous intracranial haemorrhage (ICH) is a rare complication of chronic immune thrombocytopenic purpura (ITP) in children. We report four patients with cITP who developed ICH. The latency between onset of ITP and ICH varied from 1-8 years. All our patients were profoundly thrombocytopenic (platelet count of <10 x 109/l) at the time of their intracranial bleed. The presenting features and m...

Idiopathic thrombocytopenic purpura (ITP) is an acute self-limited bleeding disorder that can progress to chronic form in 10-15% of the cases. Helicobacter pylori (H. pylori) infection is a possible cause of chronic ITP. We studied 30 children with resistant chronic ITP for H. pylori infection based on the detection of H. pylori fecal antigen. This retrospective study was based on data obtained...

Adult idiopathic thrombocytopenic purpura (ITP) is an autoimmune disorder caused by antiplatelet autoantibodies that cause platelet destruction by the reticuloendothelial system. The disease has been well-documented in the West. We studied 78 ITP patients diagnosed and followed up in a tertiary hospital, over a 10-year period, to give a profile of our local patients and their response to treatm...

Although extraintestinal manifestations of inflammatory bowel diseases are not uncommon, few reports have described concurrent idiopathic thrombocytopenic purpura (ITP). Spontaneous pneumomediastinum is also a rare complication of ulcerative colitis (UC). This report describes the case of a 14-year-old boy who experienced recurrent ulcerative colitis 3 months after temporary improvement followi...

abstract objective immune thrombocytopenic purpura (itp) manifests as an easy bruising or extravasation of blood from capillaries into skin and mucous membranes. the characteristics of acute itp in infants have rarely been described. in order to better understand acute itp in infants, the characteristics of the disease at this age group was investigated. material and methods the present descrip...
