OBJECTIVES: The improved passive immune thrombocytopenia (ITP) mouse model has been extensively utilized for the study of ITP. However, how closely this model matches the human inflammation state and immune background is unclear. Our study aimed to explore the profile of Th cytokines and Th17/Treg cells in the model. METHODS: We induced the ITP mouse model by dose-escalation injection of MWReg30. The serum levels of cytokines (IFN-γ, IL-2, IL-4, IL-10, IL-17A, and TGF-β1) were measured by enzyme-linked immunosorbent assay and the frequency of Th17 and Treg cells was measured by flow cytometry...

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...

Eltrombopag is well established in treatment of severe immune thrombocytopenia (ITP) and is increasingly commonplace in second-line management. A role is also suggested for both bridging therapy for surgery, as well as treating thrombocytopenia due to non-immune aetiologies. We present the largest single-centre experience with eltrombopag, with our cohort of 62 patients. Patients with severe ITP (n = 34) had 91·2% response, which was sustained over a median of 18·5 months. In 41·4% of ITP cases (n = 14), complete response (CR- platelet count >100 × 10(9) /l) was achieved and in 2 cases, therapy was stopped and CR maintained...

REVIEW
Nichola Cooper
The management of patients with immune thrombocytopenia (ITP) is rapidly evolving. Over the last 15 years, a number of novel treatments have improved practice, with many steroid-sparing agents and a reduction in the progression to splenectomy. Although this has improved clinical care, many therapeutic challenges remain. There is no diagnostic test, no biomarkers to direct treatment and few comparative studies to help management decisions. Development of up to date guidelines is difficult with little high-grade evidence...

BACKGROUND: Alemtuzumab is a monoclonal antibody approved for relapsing-remitting multiple sclerosis (RRMS). Although Immune thrombocytopenia (ITP) has been reported as a secondary autoimmune phenomenon following alemtuzumab infusion, immediate thrombocytopenia during the infusion has not been reported. OBJECTIVE: We report transient, reversible, self-limiting acute-onset thrombocytopenia during the first course with alemtuzumab. RESULTS AND CONCLUSION: In total, 3 of 22 paitents developed mild self-limited bruising associated with a drop in platelet count from their baseline during the intial 5-day course of alemtuzumab...

Immune thrombocytopenia (ITP) is an auto-immune condition that results in isolated thrombocytopenia associated with possibly lethal haemorrhage. In its secondary form, ITP can be triggered by many infectious and non-infectious conditions. Secondary ITP associated with tuberculosis (TB) has rarely been described in the literature. We report on a 22-year-old patient presenting with hypermenorrhoea and petechiae due to ITP secondary to tuberculous lymphadenitis. Normalisation of thrombocytopenia was only achieved after initiation of anti-tuberculosis treatment following failure of thrombocyte substitution and immune-modulatory treatment...

BACKGROUND: γ-Glutamyl hydrolase (GGH) regulates intracellular folates and antifolates such as methotrexate (MTX) for proper nucleotide biosynthesis and antifolate-induced cytotoxicity, respectively. In addition to genetic polymorphism and karyotypic abnormalities, methylation of CpG island 1 (CpG1) in the promoter region is found to modulate GGH activity by reducing GGH mRNA expression in acute lymphoblastic leukemia (ALL) cells. We aim to investigate methylation status of two CpG islands (CpG1 and CpG2) in the GGH promoter region in pediatric patients with ALL and acute myelogenous leukemia (AML)...

REVIEW
Francesco Rodeghiero, Giuseppe Carli
Since its discovery, the thrombopoietin (TPO) pathway has been an important pharmaceutical target for the treatment of thrombocytopenia. The first generation of TPO mimetics included peptide agents sharing homology with endogenous TPO, but these introduced a risk of antibody formation to endogenous TPO and were not successful. However, second-generation TPO mimetics or TPO receptor agonists (RAs) are currently being used to treat thrombocytopenia associated with a number of conditions, such as immune thrombocytopenia (ITP), severe aplastic anaemia (SAA), and hepatitis C virus-associated chronic liver disease...

BACKGROUND: Dependent on the absence or presence of associated diseases, autoimmune thrombocytopenia (ITP) can be classified as primary or secondary form. The manifestation of the associated diseases is not temporally defined and may occur during observation. Thus the question which disease is the primary one remains unanswered. METHODS: All 386 patients included in this study were treated by a single primary physician between 1996 and 2015 at the Charité Berlin and met current ITP criteria...

It has been suggested that platelet function in chronic immune thrombocytopenic purpura (ITP) may be abnormal. Thrombopoietin mimetics used for treatment can affect it, but the data remain limited. We investigated platelet function of 20 children diagnosed with severe ITP (aged 1-16 years, 12 females and eight males). Platelet functional activity in whole blood was characterized by flow cytometry before and after stimulation with SFLLRN plus collagen-related peptide. Levels of CD42b, PAC1, and CD62P, but not CD61 or annexin V, were significantly increased (P < 0...

BACKGROUND: Vitamin D receptor (VDR) gene polymorphisms have been studied in immune-mediated disorders, but not yet in immune thrombocytopenic purpura (ITP). We investigated whether VDR variants were associated with ITP in children. METHODS: The study included 44 children with a diagnosis of ITP and 100 healthy controls. Five VDR polymorphisms (Cdx-2, FokI, BsmI, ApaI and TaqI) were genotyped and used to evaluate the association of VDR variants with ITP. RESULTS: The distribution of the three Cdx-2 genotyping groups (GG, GA, and AA) was significantly different between ITP patients and controls (p=0...

Described herein, a case of Langerhans cell histiocytosis (LCH) in an adult with Idiopathic Thrombocytopenic Purpura (ITP) diagnosed at age ten. She presented with cranial diabetes insipidus, later developed hypogonadotrophic hypogonadism and multiple cervical lympadenopathy from which histopathology of excisional biopsy confirmed LCH. Magnetic resonance imaging showed thickened pituitary stalk. Association of ITP and LCH is unknown but the question of LCH presenting as isolated thrombocytopenia in childhood only to be discovered in adulthood when there was pituitary and bone involvement remains...

Immune thrombocytopenia (ITP) is an autoimmune disorder characterized by autoantibody production against platelets, increased platelet destruction, and, in some cases, impaired thrombopoiesis. The majority of affected patients have significant bleeding risks due to low platelet counts and require treatment. The etiology of ITP is an immunological labyrinth. Currently available treatment options are usually not only nonspecific, but are also associated with some risks. Areas covered: Several useful drugs for the treatment of ITP are currently available...

PROBLEM: Fetal and neonatal alloimmune thrombocytopenia is an alloimmune disorder resulting from platelet opsonization by maternal antibodies that destroy fetal platelets. As there is no antenatal screening or immunization to prevent sensitization, selection of high-risk population or the prevention of antenatal sensitization is significantly limited.
