    Abstract Abatacept is the only T cell co-stimulation modulator approved thus far for the treatment of moderate-to-severe rheumatoid arthritis (RA) and is licensed for use in patients with an inadequate response to methotrexate (MTX) and/or anti-tumor necrosis factor (anti-TNF) therapy. The upstream mechanism of action of abatacept leads to downstream effects in a variety of cell types associated with the production of autoantibodies and pro-inflammatory cytokines implicated in RA. Accumulating data also suggest effects on other cells involved in the pathogenesis of RA, including regulatory T cells and osteoclasts. Clinical trials have demonstrated that abatacept is an effective and well-tolerated treatment in RA. More recently, evidence from the

    Abstract The efficacy, safety and tolerability of i.v. abatacept are well established in patients with active RA. A s.c. abatacept formulation is now available in some countries. Here, we review clinical data for s.c. abatacept. Six trials are presented (Phase II dose-finding study, ACQUIRE, ALLOW, ACCOMPANY, ATTUNE and AMPLE) and issues important to both patients and clinicians are addressed. The primary focus assesses whether the i.v. and s.c. abatacept formulations have similar efficacy, including whether the recommended fixed dose of s.c. abatacept is comparable to the weight-tiered i.v. dosing and whether efficacy is sustained with long-term treatment. Safety and immunogenicity are also discussed, including the short- and long-term safety of s.c. abatacept, and whether immunogenicity is increased following a switch from i.v. to s.c. abatacept, after withdrawal or reintroduction of s.c. abatacept or in the absence of MTX. Year 1 data from the AMPLE study, comparing s.c. abatacept with the TNF antagonist adalimumab, are discussed. Although fewer patient-years of exposure are available for s.c. compared with i.v. abatacept, observations suggest that s.c. abatacept has a similar long-term efficacy to the i.v. formulation, improving the signs, symptoms, disease activity and physical function in patients with RA. With continued treatment, these improvements are maintained over time with high retention rates, similar to i.v. abatacept. s.c. abatacept is associated with low immunogenicity and short- and long-term safety that is consistent with i.v. abatacept. In addition, s.c. abatacept demonstrates comparable efficacy, kinetics of response, safety and radiographic inhibition to adalimumab.

    Abstract Background/aims: Ischemic colitis (IC) is most common in the elderly and patients with multiple comorbidities. It carries significant mortality. As yet no evidence-based therapeutic management exists. Aim of the study was to test therapeutic efficacy of a combination of prednisolone and antibiotics.
    Methods: Prospective cohort study with retrospective analysis performed in a single teaching hospital in Germany. Consecutive patients with strict diagnostic criteria of severe IC, including colonoscopy, histology, and laboratory tests, were recruited. Main outcome measures were in-hospital mortality and number of operations counted within the hospital stay. Severity scores were calculated and biomarkers determined during the course of the hospital stay.
    Results: A total of 342 patients with an International Classification of Diseases of IC were identified. About 151 patients met the diagnostic criteria and a total of 44 patients fulfilled all inclusion and exclusion criteria of severe IC and constituted the group of patients eligible for analysis. Five out of 44 patients (11.4%) died (in-hospital mortality). Surgery was performed in 3 patients (6.8%), 2 patients survived. The hospital stay lasted 14.0 ± 8.5 day and was significantly correlated with comorbidity (rs = 0.314, p = 0.038). No serious adverse events were observed.
    Conclusion: This is the first prospective study on therapeutic efficacy and safety in severe IC. The combination of intravenous antibiotics and intravenous prednisolone turned out to be safe and revealed promising efficacy.

    Abstract Significant advances in our understanding of RA and its management have been made in the past decade, resulting in earlier intervention with biologic DMARDs, particularly in patients with evidence of aggressive, erosive disease. Here, one such biologic therapy, the T-cell co-stimulation modulator abatacept, is discussed, exploring clinical evidence published to date on its use in patients with very early arthritis/early RA who are MTX naïve, and in patients with established RA and an inadequate response to MTX or TNF antagonists. Data from relevant clinical trials are overviewed, discussing the clinical efficacy of abatacept in early disease, the clinical outcomes over long-term treatment in different patient populations and the effects of abatacept on structural damage. Findings from integrated safety analyses of abatacept clinical trial data, representing 10,366 patient-years of exposure are described, and clinically important safety events, including serious infections, malignancies and autoimmune events, are highlighted. It is concluded that abatacept represents an effective treatment option with an established safety profile across different patient populations, including patients with both early and erosive RA and those with established disease. Furthermore, efficacy data from studies in patients with early disease suggest that the risk-benefit profile of abatacept may be more favourable when introduced earlier in the treatment paradigm.

    Abstract Both the American College of Rheumatology (ACR) and European League Against Rheumatism (EULAR) guidelines recommend the use of methotrexate (MTX) for the treatment of rheumatoid arthritis (RA) when there is no contraindication. While MTX is the foundation of RA therapy (Singh et al. in Arthritis Care Res 64:625-639,2012), absorption saturation compromises its oral bioavailability (BA). Differences in the relative BA of oral versus subcutaneous (SC) MTX demonstrate the need for guidance on successful dose-conversion strategies. This study was designed to compare MTX PK profiles as a result of MTX administration via three different treatment administrations: oral, SC MTX administered via an auto-injector (MTXAI) into the abdomen (MTXAI

    Abstract A significant percentage of patients presenting with undifferentiated arthritis (UA) will progress to rheumatoid arthritis (RA), while others will undergo spontaneous remission. Evidence supports the use of therapeutic intervention in patients with UA to delay or halt disease progression and its long-term consequences. However, there is first a need to screen patients with UA to identify those with a high probability of progressing to RA who would benefit from antirheumatic therapy. The 2010 American College of Rheumatology/European League Against Rheumatism RA classification criteria were designed for this purpose. These criteria can aid clinicians in deciding when it is appropriate to initiate therapy in patients at risk of progressing to RA. These criteria can also have important implications in reducing the inappropriate and unnecessary use of antirheumatic agents in patients less likely to develop RA, thus reducing healthcare costs and minimizing the risk of sequelae associated with these agents. Use of disease-modifying antirheumatic drugs and biologic agents in patients with UA has been associated with delays in disease progression. However, further clinical studies are needed to fully evaluate the long-term clinical and economic outcomes of these agents in patients with UA.

    Abstract: Objectives: To explore antinuclear autoantibody (ANA) and anti-double-stranded DNA (anti-dsDNA) autoantibody development during abatacept and tumour necrosis factor inhibitor (TNFi) treatment, and effects of switching from TNFi to abatacept in ANA/anti- ... ...

    Abstract Objectives: To explore antinuclear autoantibody (ANA) and anti-double-stranded DNA (anti-dsDNA) autoantibody development during abatacept and tumour necrosis factor inhibitor (TNFi) treatment, and effects of switching from TNFi to abatacept in ANA/anti-dsDNA autoantibody-positive patients.
    Methods: This was a post hoc analysis of biologic-naïve patients with active RA in ATTEST and AMPLE. In AMPLE, patients received subcutaneous abatacept or adalimumab (2 years). In ATTEST, patients received intravenous abatacept or infliximab (1 year), or placebo (6 months) then abatacept (6 months); at 1 year, all patients could receive abatacept (open-label long-term extension). Serum ANA/anti-dsDNA autoantibody levels were measured at baseline, Month 6 (ATTEST only), Years 1 and 2.
    Results: At baseline, 25.7 and 0.9% (AMPLE), and 21.6 and 8.4% of patients (ATTEST) were ANA/anti-dsDNA autoantibody positive, respectively. More baseline ANA/anti-dsDNA autoantibody-negative patients became positive during TNFi than abatacept treatment. In ATTEST (TNFi group), 48.5% (48/99; ANA) and 48.3% (57/118; anti-dsDNA) of patients seroconverted to positive status by Year 1, falling to 22.4% (22/98 ANA) and 13.3% (15/113; anti-dsDNA) by Year 2 after switching to abatacept. Of ANA/anti-dsDNA autoantibody-positive patients at Year 1, 41.9% and 68.9%, were negative at Year 2.
    Conclusions: ANA/anti-dsDNA seroconversion was more frequent with TNFi than abatacept therapy; TNFi-associated seroconversion decreased after switching from TNFi to abatacept.
