In this study, a new analytical procedure based on isotachophoresis (ITP) coupled to a multi collector inductively coupled plasma mass spectrometer named Stop-Flow-ITP-MC-ICPMS is developed for exhaustive and high-precision multi-elemental isotopic characterization. We demonstrate that Stop-Flow-ITP makes it possible to stop the analytes migration several times for a duration compatible with the detector configuration changes without losing the separation performance. With this procedure, isotope ratio measurements of four lanthanides of interest for nuclear applications (Nd, Sm, Eu and Gd) were obtained with a reproducibility better than 0...

BACKGROUND: Corticosteroid sparing is required in 15% to 40% of adults with persistent or chronic primary immune thrombocytopenic purpura (ITP). Herein, the efficacy of immunomodulatory drugs (dapsone, interferon alpha, danazol, and hydroxychloroquine as second-third-line therapies in ITP is investigated. METHODS: MEDLINE was searched for studies that included patients with persistent or chronic primary ITP and published before the end of December 2014. Two investigators independently extracted data regarding study design, patient characteristics, dosage schedule, time to response, and occurrence of adverse events...

Immune thrombocytopenic purpura (ITP) is a common hematological disease treated primarily by corticosteroids. The aim of the present study was to compare response rate between patients, underwent splenectomy vs. rituximab as second-line therapy. Adult patients diagnosed with ITP who did not respond to corticosteroids or relapsed during the period 1990-2014 were included in a quasi-experimental study. Categorical variables were compared using Fisher exact test. Response to treatment was compared using logistic regression...

Fingolimod is an oral sphingosine-1-phosphate receptor modulator which causes lymphocyte sequestration in lymph nodes and is approved for relapsing multiple sclerosis. The Therapeutic Goods Administration of Australia is aware of only one case where fingolimod preceded immune thrombocytopenic purpura (ITP) by 5 weeks. Here we report three such cases.None were on any medications known to cause ITP and routine investigations were unremarkable. All cases were treated with immunosuppression. Case 1 successfully weaned prednisolone after fingolimod cessation whereas case 2 weaned slowly while continuing fingolimod therapy...

BACKGROUND: Opportunistic invasive fungal infections (OIFIs) occur in dogs administered immunosuppressive medications. However, the epidemiology of OIFIs among dogs undergoing immunosuppressive treatment is poorly understood. The aims of this study were to (1) estimate the incidence of OIFIs among dogs diagnosed with certain immune-mediated diseases and treated with immunosuppressive drugs, and (2) determine if administration of particular drug(s) was a risk factor for OIFIs. HYPOTHESIS: Dogs receiving cyclosporine treatment (alone or as part of a multidrug protocol) are at higher risk of developing OIFIs...

Primary immune thrombocytopenia (ITP) is a disease of autoimmunity in which there are Th1/Th2 imbalance and disordered cytokine profiles. CXC chemokine ligand 16 (CXCL16) was proved to implicate in some autoimmune diseases. Our research aimed to determine plasma soluble CXCL16 (sCXCL16) levels and its effects in ITP. We used ELISA to measure plasma sCXCL16, IFN-γ and IL-4 and flow cytometry to determine expression of CXCR6 on lymphocyte subsets. We used real-time PCR to detect the CXCL16 and CXCR6 mRNA expression...

AIMS: Real-world evidence on the safety profile and costs associated with immune thrombocytopenic purpura (ITP) treatment in adults is lacking. This study quantifies and compares adverse event (AE) crude rates and costs associated with ITP treatments as found in claims data. MATERIALS AND METHODS: A retrospective claims-based analysis was conducted using IMS Pharmetrics Plus database. Included patients were ≥18 years old, with a diagnosis of ITP (2007-2012); an ITP-related claim for anti-D, intravenous immunoglobulin (IVIG), rituximab, romiplostim, or eltrombopag; and 1-year continuous enrollment (3-years for rituximab) during follow-up...

Hepatitis A is common in children and usually is a self-limiting disease. Although extrahepatic and hematological immune manifestations following acute hepatitis A virus (HAV) infection have rarely been reported, they are frequently observed in other viral hepatitis. In this paper, we report the case of a 3-year-old girl who developed immune thrombocytopenic purpura (ITP) and hemolytic anemia after HAV infection. She was presented with malaise, pallor, ecchymosis, petechiae and purpura on the trunk and extremities...

The use of on-chip isotachophoresis assays for diagnostic applications is often limited by the small volumes of standard microfluidic channels. Overcoming this limitation is particularly important for detection of 'discrete' biological targets (such as bacteria) at low concentrations, where the volume of processed liquid in a standard microchannel might not contain any targets. We present a novel microfluidic chip that enables ITP focusing of target analytes from initial sample volumes of 50 μL into a concentrated zone with a volume of 500 pL, corresponding to a 100,000-fold increase in mean concentration, and a 300,000-fold increase in peak concentration...

BACKGROUND: Common variable immunodeficiency (CVID) is the most common symptomatic primary immune deficiency of adulthood. Besides recurrent infections, autoimmune disorders-mainly cytopenias-affect 30% of patients with CVID. OBJECTIVES: To describe the efficacy and safety of facilitated subcutaneous immunoglobulin (fSCIg), which is a combination of 10% [human] SCIg with recombinant human hyaluronidase for the treatment of CVID-linked cytopenias. METHODS: We describe four women (mean age 54 years) with CVID associated with idiopathic thrombocytopenic purpura (ITP) (n=3) and autoimmune hemolytic anemia (AIHA) (n=1)...

Primary immune thrombocytopenia (ITP) is the most common cause of thrombocytopenia in children and adolescents and can be considered as a paradigmatic model of autoimmune disease. This second part of our review describes the clinical presentation of ITP, the diagnostic approach and overviews the current therapeutic strategies. Interestingly, it suggests an algorithm useful for differential diagnosis, a crucial process to exclude secondary forms of immune thrombocytopenia (IT) and non-immune thrombocytopenia (non-IT), which require a different therapeutic management...

Capillary isotachophoresis (ITP) is an electrophoretic technique offering high sensitivity due to permanent stacking of the migrating analytes. Its combination with electrospray-ionization mass-spectrometric (ESI-MS) detection is limited by the narrow spectrum of ESI-compatible components but can be compensated by experienced system architecture. This work describes a methodology for sensitive analysis of hydroxyderivatives of s-triazine herbicides, based on implementation of the concepts of moving-boundary isotachophoresis and of H(+) as essential terminating component into cationic ITP with ESI-MS detection...

Thrombocytopenia is often caused by myelosuppression during chemotherapy. However, when platelet transfusions are required, pathological conditions such as idiopathic thrombocytopenic purpura(ITP)and thrombotic thrombocytopenic purpura( TTP)also occur. We report a case of Merkel cell carcinoma complicated with severe thrombocytopenia treated with carboplatin/etoposide regimen after surgery. The patient's platelet count did not increase in spite of platelet transfusions. However, the platelet count increased after steroid treatment was chosen under the diagnosis of ITP...

BACKGROUND: In chronic immune thrombocytopenic purpura (ITP), rituximab removes the harmful autoantibodies through antibody-dependent cellular cytotoxicity. The response to rituximab in ITP is variable; the effectiveness of rituximab is influenced by the process of activation of effector fragment C gamma receptors (FcγRs). Genetic factors may affect the response to rituximab. OBJECTIVES: The influence of FcγRIIa (H131R) and FcγRIIIa (V158F) gene polymorphisms on the response to rituximab in ITP...

BACKGROUND: Trypanosoma cruzi, the etiological agent of Chagas disease, uses proline as its main carbon source, essential for parasite growth and stage differentiation in epimastigotes and amastigotes. Since proline is involved in many essential biological processes in T. cruzi, its transport and metabolism are interesting drug targets. METHODS: Four synthetic proline analogues (ITP-1B/1C/1D/1G) were evaluated as inhibitors of proline transport mediated through the T...

BACKGROUND: Most immune thrombocytopenia (ITP) is sporadic but a positive family history of ITP in some patients suggests that hereditary forms exist. Due to the rarity of familial ITP families available for study and the heterogeneity of sporadic ITP, family linkage analysis or genome wide association studies are limited. OBJECTIVES: Based on one ITP pedigree, we try to identify the predisposing gene in familial or sporadic ITP and reveal the way in which it causes thrombocytopenia...

Intrathoracic pressure (ITP) swings challenge many physiological systems. The responses of cerebral hemodynamics to different ITP swings are still less well-known due to the complexity of cerebral circulation and methodological limitation. Using frequency-domain near-infrared spectroscopy and echocardiography, we measured changes in cerebral, muscular and cardiac hemodynamics in five graded respiratory maneuvers (RM), breath holding, moderate and strong Valsalva maneuvers (mVM/sVM) with 20 and 40 cmH2O increments in ITP, moderate and strong Mueller maneuvers (mMM/sMM) with 20 and 40 cmH2O decrements in ITP controlled by esophageal manometry...

The hemodynamic effects of ventilation can be grouped into three concepts: 1) spontaneous ventilation is exercise; 2) changes in lung volume alter autonomic tone, pulmonary vascular resistance, and can compress the heart in the cardiac fossa; 3) spontaneous inspiratory efforts decrease intrathoracic pressure (ITP) increasing venous return and impeding left ventricular (LV) ejection; whereas positive pressure ventilation decreases venous return and unloads LV ejection. Spontaneous inspiratory efforts may induce acute LV failure and cardiogenic pulmonary edema...
