rheumatoid arthritis and ITP

Adrian Newland, Eun-Ju Lee, Vickie McDonald, James B Bussel
Immune thrombocytopenia (ITP) is an acquired autoimmune disorder characterized by phagocytosis and destruction of autoantibody-coated platelets via spleen tyrosine kinase (Syk)-mediated signal transduction in macrophages. Effectiveness of existing therapies varies, and even leading treatments (e.g., IVIg, splenectomy, rituximab, thrombopoietic agents) do not provide optimal management for a substantial number of patients with chronic ITP. Fostamatinib disodium is an orally-bioavailable investigational agent being developed for treatment of primary persistent/chronic adult ITP...

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...

Self-reactive antibodies represent a significant force in autoimmune disease induction. In antibody-dependent autoimmune syndromes such as immune thrombocytopenia (ITP), systemic lupus erythematosus (SLE), myasthenia gravis and rheumatoid arthritis (RA), autoantibodies exert their inflammatory effect through FcγRs, a well-established class of cell surface receptors that interact with the Fc domain of IgG. Down-regulating FcγR functionality presents an attractive strategy to treat antibody-dependent autoimmune diseases...

Autophagy involves the sequestration and lysosomal degradation of various cytoplasmic structures, including damaged organelles and invading microorganisms. Autophagy is not only an essential cell-intrinsic mechanism for protecting against internal and external stress conditions but is also key in the cellular response against microbes, in antigen processing for major histocompatibility complex (MHC) presentation, and in lymphocyte development, survival, and proliferation. In recent years, perturbations in autophagy have been implicated in a number of diseases, including autoimmune diseases, such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and multiple sclerosis (MS)...

BACKGROUND: Increased risk of B-cell non-Hodgkin lymphoma (NHL) in patients with autoimmune diseases is a known fact. An association may exist between marginal zone lymphoma (MZL) and certain autoimmune conditions and vice-versa. METHODS: Herein, we present the analysis of a series of consecutive patients (n = 24) diagnosed with MZL at our institution between 2008-2014. Our series, analyzed both retrospectively and prospectively, consisted of a blend of nodal, extranodal and splenic MZL...

The phagocyte NADPH oxidase NOX2 produces reactive oxygen species (ROS) and is a well-known player in host defence. However, there is also increasing evidence for a regulatory role of NOX2 in adaptive immunity. Deficiency in phagocyte NADPH oxidase causes chronic granulomatous disease (CGD) in humans, a condition that can also be studied in CGD mice. Clinical observations in CGD patients suggest a higher susceptibility to autoimmune diseases, in particular lupus, idiopathic thrombocytopenic purpura and rheumatoid arthritis...

BACKGROUND: Near universal administration of vaccines mandates intense pharmacovigilance for vaccine safety and a stringently low tolerance for adverse events. Reports of autoimmune diseases (AID) following vaccination have been challenging to evaluate given the high rates of vaccination, background incidence of autoimmunity, and low incidence and variable times for onset of AID after vaccinations. In order to identify biologically plausible pathways to adverse autoimmune events of vaccine-related AID, we used a systems biology approach to create a matrix of innate and adaptive immune mechanisms active in specific diseases, responses to vaccine antigens, adjuvants, preservatives and stabilizers, for the most common vaccine-associated AID found in the Vaccine Adverse Event Reporting System...

BACKGROUND: The cumulative risk of non-Hodgkin lymphoma (NHL) in Sweden by age 80 years has increased to 1.1 in women and 1.6% in men in 2011. Increased risk of NHL associated with personal histories of some autoimmune diseases (ADs) is known. It is unclear whether there are other NHL-related ADs and whether this association holds across different sex, age and year of diagnosis, or NHL histological subtypes. PATIENTS AND METHODS: Over an average of 9.4-year (maximum 47 years) follow-up of 878 161 patients diagnosed in 1964-2010 with 33 different ADs, 3096 subsequent NHL were diagnosed (data: Swedish Cancer Registry)...

Since its approved by HAS in 1998, the use of rituximab increases every year. Marketed in France under the name MabThera, rituximab is used primarily in the treatment of B-cell malignancies including follicular lymphoma, diffuse large B-cell lymphoma and chronic lymphocytic leukemia and corresponding to the three main indications for treatment. However, given its action on B cells, rituximab also proves to be effective in rheumatoid arthritis. By extension as anti-B-cell, rituximab is actually used in other autoimmune diseases: in autoimmune cytopenias as idiopathic thrombocytopenic purpura and hemolytic anemia, in vasculitis, or multiple sclerosis, it is also used in organ transplantation as kidney in prophylaxy to rejection and treatment of EBV-mediated complications...

Helicobacter pylori (H. pylori) is the main cause of chronic gastritis and a major risk factor for gastric cancer. This pathogen has also been considered a potential trigger of gastric autoimmunity, and in particular of autoimmune gastritis. However, a considerable number of reports have attempted to link H. pylori infection with the development of extra-gastrointestinal autoimmune disorders, affecting organs not immediately relevant to the stomach. This review discusses the current evidence in support or against the role of H...

Previous research has suggested autoimmune diseases are risk factors for developing venous thromboembolism (VTE). We assessed whether having diagnoses of selected autoimmune diseases associated with antiphospholipid antibodies--autoimmune hemolytic anemia (AIHA), immune thrombocytopenic purpura (ITP), rheumatoid arthritis (RA), and systemic lupus erythematosus (SLE)--were associated with having a VTE diagnosis among US adult hospitalizations. A cross-sectional study was conducted using the 2010 Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality...

T cell immunoglobulin and mucin domain-3 (TIM-3), originally identified as a T helper (Th) 1-specific type I membrane protein, plays a vital role in Th1 immunity and tolerance induction through interaction with its ligand, galectin-9. The binding of TIM-3 by galectin-9 serves to downregulate Th1 responses. Moreover, the regulatory function of TIM-3 has been extended to other cells, such as Th17 cells, CD4(+) CD25(+) regulatory T cells (Tregs), CD8(+) T cells and certain innate immune cells. Previous studies have acknowledged that the TIM-3 pathway is involved in the pathogenesis of several human autoimmune diseases, such as systemic lupus erythematous, rheumatoid arthritis and aplastic anaemia...

Abstract Immune thrombocytopenic purpura (ITP) associated with rheumatoid arthritis (RA) is relatively rare. We describe five cases of RA with ITP. In all five patients, platelet counts were low, platelet-associated IgG levels were elevated, and bone marrow aspiration showed megakaryocytosis. Glucocorticoid therapy was effective in three cases, but the other two cases required immunosuppressants or intravenous γ-globulin in addition to glucocorticoid. We review the reported cases of RA with ITP and discuss the pathophysiology and differential diagnosis of thrombocytopenia in RA...

Rituximab is recognized as a useful drug for the treatment of B-cell non-Hodgkin's lymphoma and its use has been extended to such diseases as idiopathic thrombocytopenic purpura, thrombotic thrombocytopenic purpura, chronic rheumatoid arthritis and ANCA-associated vasculitides. One serious complication associated with its use is the reactivation of hepatitis B virus and the search for methods to prevent this occurrence has resulted in the rapid accumulation of knowledge. In this review, we discuss case analyses from our department and other groups and outline the current knowledge on the topic and the remaining issues...

OBJECTIVES: The aim of this study was to investigate whether the quadrivalent human papillomavirus (HPV) vaccine Gardasil is associated with a change in the risk of autoimmune disorders (ADs) in young female subjects. DESIGN: Systematic case-control study of incident ADs associated with quadrivalent HPV vaccination in young women across France. PARTICIPANTS AND SETTING: A total of 113 specialised centres recruited (from December 2007 to April 2011) females aged 14-26 years with incident cases of six types of ADs: idiopathic thrombocytopenic purpura (ITP), central demyelination/multiple sclerosis (MS), Guillain-Barré syndrome, connective tissue disorders (systemic lupus erythematosus, rheumatoid arthritis/juvenile arthritis), type 1 diabetes mellitus and autoimmune thyroiditis...

Non-receptor type of protein-tyrosine kinase Syk (spleen tyrosine kinase) was isolated in University of Fukui in 1991. Syk is most highly expressed by haemopoietic cells and known to play crucial roles in the signal transduction through various immunoreceptors of the adaptive immune response. However, recent reports demonstrate that Syk also mediates other biological functions, such as innate immune response, osteoclast maturation, platelet activation and cellular adhesion. Moreover, ectopic expression of Syk by epigenetic changes is reported to cause retinoblastoma...

Non-receptor type of protein-tyrosine kinase Syk (spleen tyrosine kinase) was isolated in the University of Fukui in 1991. Syk is known to be essential for the various physiological functions, especially in hematopoietic lineage cells. Moreover, ectopic expression of Syk by epigenetic changes is reported to cause retinoblastoma. Recently, novel Syk inhibitors were developed and its usefulness has been evaluated in the treatment of allergic rhinitis, rheumatoid arthritis, and idiopathic thrombocytopenic purpura...

Rituximab (RTX) is used off-label to treat immune thrombocytopenia (ITP) but the regimen now commonly used in rheumatoid arthritis has not been evaluated in ITP. The aim of this large French multicenter retrospective study was to compare the efficacy and safety of two RTX regimens in adult's ITP. The efficacy of two (RTX) regimens: standard therapy of 375 mg/m(2) weekly for 4 weeks vs. a rheumatoid arthritis (RA) regimen of 1,000 mg on days 1 and 15, to treat ITP was compared. We included adults patients with previously primary ITP treated with RTX instead of treated primary ITP...
