Bleeding is the most important clinical outcome in patients with immune thrombocytopenia (ITP), and the goal of therapy in such cases is to treat or prevent bleeding. The frequency of and risk factors for bleeding events in ITP have only recently been identified in several large-scale studies. However, there is little published information about severe life-threatening bleeding in ITP. To clarify the clinical features of life-threatening bleeding in patients with primary ITP, we systematically reviewed the medical records of all ITP patients that were admitted to our hospital between January 1, 1992, and December 31, 2015...

We present the case where immune thrombocytopenia (ITP) and essential thrombocythemia (ET) sequentially appeared in the space of twenty-one years of follow-up. Impaired platelet production is present in both diseases, but clinical presentation and treatment are different. On the basis of this case history a possible role of autoimmunity as a predisposing factor to myeloproliferation has been discussed.

BACKGROUND: An accessory spleen (AS) is a lobule of splenic tissue found in ectopic locations. Identification of AS is particularly important in patients with immune thrombocytopenia (ITP) requiring splenectomy as unrecognized AS can later cause refractory symptoms. The AS can also be a source of significant intraabdominal hemorrhage. The aim of this meta-analysis was to systematically analyze the data on the prevalence, number, location, and morphometry of AS. MATERIALS AND METHODS: An extensive search of the major electronic databases was conducted to identify all studies that reported relevant data on the AS...

Helicobacter pylori is a gram-negative, flagellate, microaerophilic bacterium identified for the first time about 30 years ago, as a pathogenic factor of gastritis and peptic ulcer. Soon after, it was linked to several gastrointestinal and extra-gastrointestinal diseases (hematological, cardiovascular, neurological, pulmonary and ocular diseases, obesity, diabetes mellitus, growth retardation and extragastric MALT lymphoma). Association and possible cause-effect correlation with H. pylori infection were suggested in diseases of dermatological interest such as chronic urticaria, rosacea, Henoch-Schoenleins purpura, idiopathic thrombocytopenic purpura, cutaneous and oral lichen planus, atopic dermatitis, recurrent aphthous stomatitis, systemic sclerosis, psoriasis, Sjögrens syndrome, Behçet's disease, pruritus, alopecia areata, primary cutaneous marginal zone B-cell lymphomas, vitiligo, chronic prurigo, multiformis, prurigo nodularis, leukocytoclastic vasculitis, prurigo pigmentosa, eczema nummulare, primary cutaneous MALT-type lymphoma, sublamina densa-type linear IgA bullous dermatosis, Sweet's syndrome, cutaneous T-cell pseudolymphoma and pemphigus vulgaris...

OBJECTIVES: Immune thrombocytopenia of childhood (platelet count <100,000/μL) is the most common cause of thrombocytopenia in children. Patients typically present with bruising and bleeding in the setting of thrombocytopenia. Although it is usually short-lived, some cases persist and are unresponsive to treatment. This can lead to exposure to a variety of treatment regimens including immunosuppressants and splenectomy. The goal of this report is to present a case of chronic ITP of childhood that responded to tonsillectomy addressing the tonsils as a source of chronic infection and inflammation triggering ITP...

The U.S. Food and Drug Administration (FDA) approved eltrombopag for pediatric patients with chronic immune (idiopathic) thrombocytopenia (ITP) ages ≥6 on June 11, 2015, and ages ≥1 on August 24, 2015. Approval was based on the FDA review of two randomized trials that included 159 pediatric patients with chronic ITP who had an insufficient response to corticosteroids, immunoglobulins, or splenectomy. This manuscript describes the basis for approval of these applications. The FDA concluded that eltrombopag has shown efficacy and a favorable benefit to risk profile for pediatric patients with chronic ITP...

Primary immune thrombocytopenia (ITP) is an autoimmune disorder characterized by early platelet destruction due to antiplatelet autoantibodies. Recently, significant progress has been made regarding the pathophysiology of ITP. Nonetheless, the diagnosis of ITP in daily clinical practice is still based on differential diagnosis because of the lack of laboratory tests that can diagnose autoimmunity in ITP. In this chapter, the recent topics regarding the diagnosis and management of ITP have been reviewed.

INTRODUCTION: Pediatric immune thrombocytopenia (ITP) may be associated with significant burden on children and their parents/caregivers. Thrombopoietin (TPO) receptor agonists (RAs) have been used to treat adult patients with chronic ITP (cITP) for nearly a decade and following pediatric studies Eltrombopag has been recently approved for pediatric cITP in the United States and Europe. TPO-RA s may help reduce the risk of bleeding and the need for conventional ITP therapies. REVIEW: In this review, the clinical data demonstrating the efficacy and safety of TPO-RAs in pediatric ITP are evaluated, key recommendations regarding safe administration of eltrombopag are provided, and potential future directions in management of pediatric ITP are discussed...

WHAT IS KNOWN AND OBJECTIVES: Rituximab is a chimeric monoclonal anti-CD20 antibody approved for the treatment of some lymphoid malignancies as well as for autoimmune diseases including rheumatoid arthritis (RA), idiopathic thrombocytopenic purpura (ITP) and vasculitis. Generally, rituximab is well tolerated; nevertheless, some patients develop adverse effects including infusion reactions. Albeit rare, these reactions may in some cases be life-threatening conditions. Rituximab cardiovascular side effects include more common effects such as hypertension, oedema and rare cases of arrhythmias and myocardial infarction...

REVIEW

Immune thrombocytopenia (ITP) is a rare autoimmune disease due to an abnormal T cell response, notably supported by splenic T follicular helper cells, that stimulates the proliferation and differentiation of autoreactive B cells. The antiplatelet autoantibodies they produce facilitate platelet phagocytosis by macrophages, essentially in the spleen. Macrophages contribute to the perpetuation of the auto-immune response as the main antigen-presenting cell during ITP. CD8(+) T cells also participate to thrombocytopenia by increasing platelet apoptosis...

AIM: Childhood immune thrombocytopenia (ITP) has been associated with low bleeding rates and a high frequency of spontaneous remission. Although current guidelines suggest that most patients are just observed, children still receive platelet-enhancing therapies for fear of bleeding complications. We hypothesised that a standardised protocol with a step-down approach would reduce hospitalisation and treatment use. METHOD: A retrospective chart review was performed on patients diagnosed with acute ITP between January 2010 and December 2014, before (n = 54) and after (n = 37) the standardised protocol, which was introduced in January 2013...

Stereotactic radiosurgery (SRS) is the accurate, conformal delivery of high-dose radiation to well-defined targets while minimizing normal structure doses via steep dose gradients. While inverse treatment planning (ITP) with computerized optimization algorithms are routine, many aspects of the planning process remain user-dependent. We performed an international, multi-institutional benchmark trial to study planning variability and to analyze preferable ITP practice for spinal robotic radiosurgery. 10 SRS treatment plans were generated for a complex-shaped spinal metastasis with 21 Gy in 3 fractions and tight constraints for spinal cord (V14Gy<2 cc, V18Gy<0...
