Immune thrombocytopenia (ITP) is a complex autoimmune disease characterized by low  platelet counts. The pathogenesis of ITP remains unclear although both antibody-mediated and/or  T cell-mediated platelet destruction are key processes. In addition, impairment of T cells, cytokine  imbalances, and the contribution of the bone marrow niche have now been recognized to be  important. Treatment strategies are aimed at the restoration of platelet counts compatible with  adequate hemostasis rather than achieving physiological platelet counts...

PURPOSE: In this study, we examined the length of stay, hospitalization cost, and risk of in-hospital mortality among US adult inpatients with immune thrombocytopenic purpura (ITP). METHODS: We analyzed nationally representative data obtained from Nationwide/National Inpatient Sample database of discharges from 2006 to 2012. RESULTS: In the US, there were an estimated 296,870 (95% confidence interval [CI]: 284,831-308,909) patient discharges recorded for ITP from 2006 to 2012, during which ITP-related hospitalizations had increased steadily by nearly 30%...

Splenic macrophages play a key role in immune thrombocytopenia (ITP) pathogenesis by clearing opsonized platelets. Fcγ receptors (FcγR) participate to this phenomenon but their expression on splenic macrophages and their modulation by treatments have scarcely been studied in human ITP. We aimed to compare the phenotype and function of splenic macrophages, between six controls and 24 ITP patients, and between ITP patients according to the treatments they received prior to splenectomy. CD86, HLA-DR and FcγR expression were measured by flow cytometry on splenic macrophages...

During the last decade, the development of large clinical and population-based cohorts led to new findings in the epidemiology and the pharmacoepidemiology of immune thrombocytopenia (ITP). The incidence is estimated to 3-4 for 10(5) inhabitants/year, with a slight female predominance and peaks in children and patients after 60 years. The incidence rate is 9 for 10(5) inhabitants/year in males after 75 years. Variations across ethnic groups are discussed. In France, there is a North-South gradient and a peak of incidence during winter suggesting the role of viruses in ITP pathophysiology...

Immune thrombocytopenia (ITP) in adulthood is characterized by chronic relapsing course. Despite the efficacious first line treatment (corticosteroid, intravenous immunoglobulin), majority of patients will enter the chronic phase warranting another treatment approach. Until recently, splenectomy performed in ITP chronic phase represented the standard of care with long-term remissions in more than 70% of patients, but however has never been tested in clinical trials. However, with the advances of our understanding of ITP pathophysiology and the shifting focus on megakaryocyte impairment, novel drugs were introduced in treatment paradigm, mainly trombopoietin receptor agonists (TPO-RAs); romiplostim and eltrombopag...

The autoimmune cytopenias are a related group of disorders in which differentiated hematopoietic cells are destroyed by the immune system. Single lineage disease is characterized by the production of autoantibodies against red cells (autoimmune hemolytic anemia [AIHA]), platelets (autoimmune thrombocytopenia [ITP]) and neutrophils (autoimmune neutropenia [AIN]) whereas multilineage disease may include various combinations of these conditions. Central to the genesis of this disease is the breakdown of central and/or peripheral tolerance, and the subsequent production of autoantibodies by both tissue and circulating self-reactive B lymphocytes with support from T helper lymphocytes...

The recent large decrease in splenectomy use for chronic immune thrombocytopenia (ITP) is partly due to still-unsolved questions about long-term safety. We performed the first single-center exposed/unexposed cohort study evaluating the long-term incidence of splenectomy complications in patients with primary ITP. Overall, 83 patients who underwent splenectomy more than 10 years ago (exposed) were matched with 83 nonsplenectomized patients (unexposed) on the date of ITP diagnosis ±5 years, age and gender. After a median follow-up of 192 months (range 0...

Immune thrombocytopenia (ITP) is an autoimmune condition that can cause life-threatening bleeding. ITP may develop idiopathically, after an infection or administration of a medication, or as a comorbid condition. Treatment depends on whether life-threatening, active bleeding is occurring. Although corticosteroids remain a standard of care, new medications offer patients an alternative to splenectomy when other pharmacologic treatments fail.

Immune thrombocytopenia purpura (ITP) may need splenectomy after failure of medical treatment. The aim of this study was to explore the outcome of splenectomy in chronic ITP and to point out factors which can predict better response to splenectomy. This retrospective chart review was conducted at the Aga Khan University Hospital, Karachi, and comprised adult patients who underwent splenectomy for ITP from October 2005 to December 2015. Of the 51 patients, 37(72.5%) were females and 14(27.5%) were males. The overall median age was 32 years (interquartile range: 18-65 years)...

The objective of our study is to present two cases showing the effects of traditional Korean herbal medicines based on traditional Korean medicine (TKM) for the treatment of immune thrombocytopenic purpura (ITP). One patient showed no response to treatment with steroids and an immunosuppressive agent. Moreover, liver toxicity and side effects of steroids were evident. However, after he ceased conventional treatment and started to take an herbal medicine, his liver function normalized and the steroid side effects resolved...

Immune thrombocytopenic purpura (ITP) causes thrombocytopenia through the autoimmune destruction of platelets. Corticosteroids remain the first line of therapy, and traditionally splenectomy has been the second. While the availability of thrombopoietin receptor agonists (TPO-RAs) has expanded treatment options, there is little data for the ideal management of these agents in preparation for splenectomy. Thrombocytosis has been reported after splenectomy in patients treated with TPO-RA preoperatively, with one prior case requiring plateletpheresis for symptomatic thrombocytosis...

Splenectomy is the definitive second-line therapy for refractory immune thrombocytopenic purpura (ITP), and has a reported response rate of 50-80%. Medical attention should be reconsidered when there is no evidence of accessory spleen in refractory ITP patients after splenectomy. The purpose of this study was to determine whether platelet count evolution differs between patients with a successful or unsuccessful result after splenectomy for ITP. Archived records of 104 consecutive patients that underwent splenectomy for ITP were reviewed...

The study aimed to investigate the long-term outcomes of laparoscopic splenectomy (LS) in Chinese patients with chronic idiopathic thrombocytopenic purpura (ITP). This was a retrospective analysis of 114 patients with ITP who underwent LS from 2001 to 2013. Patients were classified according to response at last contact: complete response (CR), partial response (PR), and no response (NR). Patients with CR had the highest platelet levels and patients with NR had the lowest. A correlation was observed between postoperative peak platelet count and platelet count on 2-month postoperative (r=0...

INTRODUCTION: Corticosteroids are still the standard first-line treatment for immune thrombocytopenic purpura (ITP). As second-line therapy, splenectomy and Rituximab are both recommended. The aim of our study was to compare the efficacy of Rituximab to splenectomy in persistent or chronic ITP patients. METHODS: Between January 1999 and March 2015, we retrospectively selected all consecutive patients who underwent an ITP second-line treatment: Rituximab or splenectomy...

Thrombopoietin receptor (TPO-R) agonists have been shown to be effective in refractory chronic immune thrombocytopenia (ITP); however, their efficacy in patients under critical care is not known. We report the case of a female patient with a newly diagnosed ITP who experienced severe bleeding from an external wound. The patient was administered the standard treatments for ITP, which are high-dose intravenous immunoglobulin (IVIg) and corticosteroids. However, following failure of these treatments, we administered romiplostim on day 6 after the onset of ITP...

Evidence-based medicine is growing in immune thrombocytopenia (ITP), but solid clinical data are still lacking in many areas. A majority of children has self-limited ITP, but chronic symptomatic ITP exists also in pediatrics. Management includes a watch-and-wait strategy for children with newly diagnosed ITP and no or mild bleeding, and immunoglobulins and corticosteroids, if more bleeding and mucous membrane involvement is present. Treatment endpoints differ in clinical research and in clinical practice. The requirement of platelet enhancing drugs needs to be better defined in guidelines...

We present a 7-year-old boy with recurrent thrombocytopenia after primary laparoscopic splenectomy for immune thrombocytopenia (ITP). Imaging modalities (ultrasound, computed tomography scan, and scintigraphy) revealed two accessory spleens while the subsequent second laparoscopy revealed 11, which were successfully removed. The relevant medical literature is reviewed, and the value of laparoscopy for chronic ITP is highlighted.
