OBJECTIVES: The characteristics of T cells targeted by abatacept (ABT) in cases of rheumatoid arthritis (RA) are still unknown. The goal of the study was to determine the pathogenicity of T cells and the predictors of therapeutic effects of ABT. METHODS: We analysed the peripheral T cell phenotype of 34 RA patients via flow cytometry. The correlation of the phenotypes of CD4+ T cells with clinical disease activity and change in CD4+ T cell subsets at baseline and 24 weeks after ABT treatment were evaluated...

BACKGROUND: Regulatory T cells (Tregs) play a role in the suppression of inflammation in autoimmune diseases, and lymphocyte activation gene 3 (LAG3) was reported as a marker of interleukin (IL)-10-producing Tregs. We aimed to clarify the function of human IL-10-producing CD4(+)CD25(-)LAG3(+) T cells (LAG3(+) Tregs) and their association with rheumatoid arthritis (RA). METHODS: LAG3(+) Tregs of human peripheral blood mononuclear cells (PBMCs) were cultured with B cells and follicular helper T cells to examine antibody suppression effects...

This case report describes the re-administration of abatacept to successfully reduce the articularsymptoms of a patient with rheumatoid arthritisduring the intensive phase of anti-tuberculous therapy. A 75-year-old man developed active pulmonary tuberculosis during the administration of abatacept for rheumatoid arthritis. The patient experienced a paradoxical reaction and exacerbation of rheumatoid arthritis that caused us to discontinue the abatacept. Later re-administration of abatacept along with anti-tuberculosis treatment led to well-controlled rheumatoid arthritis without exacerbation of the tuberculosis...

BACKGROUND: Biologic disease-modifying anti-rheumatic drugs (biologics) are highly effective in treating rheumatoid arthritis (RA), however there are few head-to-head biologic comparison studies. We performed a systematic review, a standard meta-analysis and a network meta-analysis (NMA) to update the 2009 Cochrane Overview. This review is focused on the adults with RA who are naive to methotrexate (MTX) that is, receiving their first disease-modifying agent. OBJECTIVES: To compare the benefits and harms of biologics (abatacept, adalimumab, anakinra, certolizumab pegol, etanercept, golimumab, infliximab, rituximab, tocilizumab) and small molecule tofacitinib versus comparator (methotrexate (MTX)/other DMARDs) in people with RA who are naive to methotrexate...

Abatacept is a fusion protein (CTLA4-Ig) and therapeutic molecule labeled for the treatment of rheumatoid arthritis (RA). Abatacept acts both by disrupting the CD28-mediated activation of T cells and by interacting with CD80/CD86 molecules present on antigen presenting cells such as monocytes and memory B cells. Accordingly and to evaluate clinical and biological parameters associated with response to abatacept, a retrospective monocentric study was conducted in 43 patients with RA, and the clinical response was evaluated at 6 months according to EULAR response criteria...

BACKGROUND: Plasma concentrations of lipoprotein (a) (Lp(a)), a lipoprotein with atherogenic and thrombogenic properties, have a strong genetic basis, although high concentrations of Lp(a) have also been reported in the context of inflammation, as in rheumatoid arthritis (RA). Few studies evaluate the impact of biologic therapies (BT) on Lp(a) in RA, taking into account that with these new therapies a better control of inflammation is achieved. OBJECTIVE: The aim of the study was to evaluate the plasma concentrations of Lp(a) in Spanish RA patients on BT attending rheumatology outpatient clinics...

BACKGROUND: Spending on biologic drugs is a significant driver of drug expenditures for payers in private health plans. Biologic disease-modifying antirheumatic drugs (DMARDs) are some of the most effective and costly treatments in a physician's arsenal. Understanding the total annual expenditure, the average cost per prescription, and the impact of cost-sharing is important for drug benefit managers. OBJECTIVE: To assess drug utilization, expenditures, out-of-pocket (OOP) cost, and price trends of biologic DMARDs in patients with rheumatoid arthritis (RA) in a large managed care organization...

Juvenile idiopathic arthritis is the most common chronic rheumatic disease of unknown aetiology in childhood and predominantly presents with peripheral arthritis. The disease is divided into several subgroups, according to demographic characteristics, clinical features, treatment modalities and disease prognosis. Systemic juvenile idiopathic arthritis, which is one of the most frequent disease subtypes, is characterized by recurrent fever and rash. Oligoarticular juvenile idiopathic arthritis, common among young female patients, is usually accompanied by anti-nuclear antibodie positivity and anterior uveitis...

BACKGROUND: New targeted therapies and improved treatment strategies have dramatically improved the outcomes of patients with rheumatoid arthritis (RA). However, it is unknown whether different early aggressive interventions can induce stable remission or a low-active disease state that can be maintained with conventional synthetic disease-modifying antirheumatic drug (csDMARD) therapy, and whether they differ in efficacy and safety. The Nordic Rheumatic Diseases Strategy Trials And Registries (NORD-STAR) study will assess and compare (1) the proportion of patients who achieve remission in a head-to-head comparison between csDMARD plus glucocorticoid therapy and three different biological DMARD (bDMARD) therapies with different modes of action and (2) two de-escalation strategies in patients who respond to first-line therapy...

Objective.: The aim of this study was to assess the therapeutic effects of biological DMARDs (bDMARDs) on the diversity of immune cell phenotypes in peripheral blood of patients with RA. Methods.: Peripheral immune cell phenotypes were determined in 108 RA patients who were non-responsive to conventional DMARDs and 33 healthy control subjects by eight-colour flow cytometry. We also examined the correlation between the phenotypes and clinical findings and assessed the effects of 24-week treatment with bDMARDs...

Chronic Inflammatory Demyelinating Polyradiculoneuropathies are a group of autoimmune neuropathies with a chronic course. Lewis-Sumner syndrome is a variant of this disease, characterized by an asymmetrical distal and mostly motor involvement, predominating at upper limb. We report the case of a patient who developed almost currently rheumatoid arthritis and Lewis-Sumner syndrome, which raised the problem of therapeutic intensification for his rheumatism when methotrexate proved to be ineffective. Finally, rituximab had been introduced by common consent with neurologists, and the patient noticed an improvement fifteen days after the first infusion...

Recent insights in rheumatoid arthritis (RA) necessitated updating the European League Against Rheumatism (EULAR) RA management recommendations. A large international Task Force based decisions on evidence from 3 systematic literature reviews, developing 4 overarching principles and 12 recommendations (vs 3 and 14, respectively, in 2013). The recommendations address conventional synthetic (cs) disease-modifying antirheumatic drugs (DMARDs) (methotrexate (MTX), leflunomide, sulfasalazine); glucocorticoids (GC); biological (b) DMARDs (tumour necrosis factor (TNF)-inhibitors (adalimumab, certolizumab pegol, etanercept, golimumab, infliximab), abatacept, rituximab, tocilizumab, clazakizumab, sarilumab and sirukumab and biosimilar (bs) DMARDs) and targeted synthetic (ts) DMARDs (Janus kinase (Jak) inhibitors tofacitinib, baricitinib)...

WHAT IS KNOWN AND OBJECTIVE: Kaposi's sarcoma (KS) is a malignant neoplasm caused by HHV-8, a pathogen that leads to endothelial cell transformation when host defences are weakened. CASE DESCRIPTION: Here we report the first case of KS during treatment with abatacept, a biologic agent targeting T-cell costimulation. The patient was a 64-year-old female with rheumatoid arthritis who developed multiple firm, purple-reddish nodules on the dorsal aspect of the right hand...

Heart failure (HF) is a leading cause of mortality. Inflammation is implicated in HF, yet clinical trials targeting pro-inflammatory cytokines in HF were unsuccessful, possibly due to redundant functions of individual cytokines. Searching for better cardiac inflammation targets, here we link T cells with HF development in a mouse model of pathological cardiac hypertrophy and in human HF patients. T cell costimulation blockade, through FDA-approved rheumatoid arthritis drug abatacept, leads to highly significant delay in progression and decreased severity of cardiac dysfunction in the mouse HF model...
