The authors present a case report of a patient discovered to have a rotatory subluxation of the C1–2 joint and a large retroodontoid pannus with an enhancing lesion in the odontoid process eventually proving to be caused by gout. This patient represented a diagnostic conundrum as she had known prior diagnoses of not only gout but also sarcoidosis and possible rheumatoid arthritis, and was in the demographic range where concern for an oncological process cannot fully be ruled out. Because she presented with signs and symptoms of atlantoaxial instability, she required posterior stabilization to reduce the rotatory subluxation and to stabilize the C1–2 instability. However, despite the presence of a large retroodontoid pannus, she had no evidence of spinal cord compression on physical examination or imaging and did not require an anterior procedure to decompress the pannus. To confirm the diagnosis but avoid additional procedures and morbidity, the authors proceeded with the fusion as well as a posterior biopsy to the retroodontoid pannus and confirmed a diagnosis of gout.

Abstract Objectives To examine whether serum antibodies against selected periodontal pathogens are associated with early symptoms of rheumatoid arthritis (RA) development in healthy individuals at risk of developing the disease. Methods Within an ongoing study cohort of first-degree relatives of patients with RA (RA-FDRs), we selected four groups corresponding to specific preclinical phases of RA development (n = 201). (1) RA-FDR controls without signs and symptoms of arthritis nor RA-related autoimmunity (n = 51); (2) RA-FDRs with RA-related autoimmunity (n = 51); (3) RA-FDRs with inflammatory arthralgias without clinical arthritis (n = 51); (4) RA-FDRs who have presented at least one swollen joint (“unclassified arthritis”) (n = 48). Groups were matched for smoking, age, sex and shared epitope status. The primary outcome was IgG serum levels against five selected periodontal pathogens and one commensal oral species assessed using validated-in-house ELISA assays. Associations between IgG measurements and preclinical phases of RA development were examined using Kruskal-Wallis or Mann-Whitney tests (α = 0.05). Results None of the IgGs directed against individual periodontal pathogens significantly differed between the four groups of RA-FDRs. Further analyses of cumulated IgG levels into bacterial clusters representative of periodontal infections, revealed significantly higher IgG titers against periodontopathogens in anti-citrullinated protein antibodies (ACPA)-positive RA-FDRs (p = 0.015). Current smoking displayed a marked trend towards reduced IgG titers against periodontopathogens. Conclusion Our results do not suggest an association between serum IgG titers against individual periodontal pathogens and specific preclinical phases of RA development. However, associations between cumulative IgG titers against periodontopathogens and the presence of ACPAs suggest a synergistic contribution of periodontopathogens to ACPA development.

Eight of 70 children with juvenile rheumatoid arthritis have developed iridocyclitis. This complication occurred more frequently in patients with monoarticular and pauciarticular disease (29%) than in patients with polyarticular disease (2%). Seven of eight patients with iridocyclitis have monoarticular or pauciarticular disease; none has had prominent systemic manifestations or evidence of ankylosing spondylitis. Iridocyclitis preceded joint manifestations in two of the patients and followed arthritis by 1 to 10 years in six of the patients. Activity of iridocyclitis and arthritis seemed unrelated; four patients developed iridocyclitis while arthritis was inactive. In seven children iridocyclitis began insidiously without acute symptoms. Eye involvement has remained unilateral in six patients. Six children have had significant decrease in visual acuity, and six continue to have active ocular inflammation despite therapy. Iridocyclitis is potentially a major cause of disability in juvenile rheumatoid arthritis. Early signs and symptoms may be minimal. Patients at risk are those with limited forms of joint disease. Early detection and therapy are crucial for prevention of permanent ocular damage. Careful eye examination should be a routine part of physical examination of children with rheumatoid arthritis, and periodic slit lamp examinations should be performed even when arthritis is in remission.

Rheumatoid arthritis is a leading musculoskeletal cause of disability in Western society. Therapeutic options have expanded rapidly with the advent of biological agents as treatment options. One of these, tocilizumab, targets the interleukin-6 receptor and has been approved since the late 2000s in many jurisdictions. This approval was based on 6–12 month trials. It is now appropriate to look at longer-term studies and what new insights they have provided into this agent. Data are based largely on observational studies with their well-known limitations as well as some further randomized trials and provide a number of important observations regarding both efficacy and safety. In conclusion, the longer-term data suggest tocilizumab efficacy increases over time for both signs and symptoms and radiographic change. It is also corticosteroid sparing. The safety data are consistent with the shorter-term trials and are largely reassuring but some questions still remain over cardiovascular safety and cancer risk.

Rheumatoid arthritis (RA) is among the most common forms of chronic inflammatory arthritis. It affects approximately 1% of adults and is two to three times more prevalent in women than in men. There are no specific laboratory tests for RA; diagnosis depends on a constellation of signs and symptoms that can be supported by serology and radiographs. The disease evolves over many years as a consequence of repeated environmental stress causing inflammation and immune activation followed by a breakdown of tolerance in individuals with a specific genetic background. This review describes the definition of RA; its etiology, including genetics, infections, the role of smoking and citrullination of proteins, and epigenetic mechanisms; and its pathogenesis, including synovial histopathology, bone and cartilage damage, adaptive and innate immunity, and the role of cytokines and intracellular signaling. Tables include the 1987 American Rheumatism Association criteria for the classification of RA and the 2010 American College of Rheumatology/European League Against Rheumatism classification for RA. Figures show citrullinated proteins in airway cells, a section of a proliferative synovium from a patient with a classic RA, and scalloped regions of erosion at the junction between a proliferative inflamed rheumatoid synovium and the bone. This review contains 3 highly rendered figures, 2 tables, and 71 references.

Background:Biologics for the treatment of rheumatoid arthritis (RA) have different modes of action to target auto-inflammatory processes causing the signs and symptoms of the disease. Different biologics may thus have different effects on inflammatory markers. For instance, previous studies have shown that the interleukin-6-inhibitor tocilizumab (TOC) decreases the level of acute phase reactants (APRs) [1]. Such direct effects on inflammatory markers may lead to an overestimation of clinical response if disease activity is measured via scores including inflammatory markers, such as the Disease Activity Score 28 (DAS 28). The detected changes in disease activity may not adequately reflect the clinical improvement of signs and symptoms.Objectives:In our study, we compared biologics with each other using two different disease activity scores: the DAS 28 including APRs and the clinical disease activity index (CDAI) excluding APRs. The aim of this study was to assess whether the use of the two different scores affects comparative effectiveness studies on biologics for the treatment of RA.Methods:We compared results on the comparative effectiveness of biologics using the corresponding thresholds for low disease activity (LDA) for the DAS 28 (< 3.2) and the CDAI (≤ 10). We performed two separate network meta-analyses (NMAs) after a thorough step-by-step evaluation of the similarity, homogeneity and consistency assumptions of the patient populations and the study data.Our study formed part of a systematic review (including NMAs) that was largely based on clinical study reports and re-analyses of LDA using individual patient data provided by sponsors for studies conducted up to 2017. Thus, the analyses include hitherto unknown data on LDA analysed by means of the CDAI, especially data from older studies. An extensive comparison of DAS 28 and CDAI in different patient populations was possible.Results:For all analysed patient populations, comparisons of TOC versus other biologics yielded remarkable results: advantages for TOC were found in NMAs using the DAS 28, which were not confirmed in NMAs using the CDAI. For methotrexate (MTX)-naïve patients, using the DAS 28, TOC showed a greater benefit than abatacept (ABA), certolizumab pegol (CZP), and etanercept (ETA), which was not confirmed by the CDAI. In contrast, TOC showed less benefit than adalimumab (ADA) and ETA. For patients after MTX failure and using the DAS 28, TOC showed a greater benefit than ABA, ADA, anakinra (ANA), ETA, golimumab (GOL), and infliximab (INF). With the exception of ANA, these advantages were not confirmed by the CDAI. Similar differences between DAS 28 and CDAI were shown in patients treated with biologics in monotherapy or after failure of biologics.Conclusion:In comparative effectiveness studies of biologics, the assessment of LDA using the DAS 28 instead of the CDAI leads to a consistent overestimation of the benefit of TOC in all patient populations, regardless of pre-treatment or combined therapy with MTX. The inclusion of APRs in disease activity scores may thus introduce bias. A score excluding inflammatory markers should therefore be used to ensure valid results.References:[1]Smolen JS, Aletaha D.

ObjectivesSustained disease-modifying antirheumatic drug (DMARD)-free status, the sustained absence of synovitis after cessation of DMARD therapy, is infrequent in autoantibody-positive rheumatoid arthritis (RA), but approximates cure (ie, disappearance of signs and symptoms). It was recently suggested that immunological remission, defined as disappearance of anti-citrullinated protein antibodies (ACPA) and rheumatoid factor (RF), underlies this outcome. Therefore, this long-term observational study determined if autoantibodies disappear in RA patients who achieved sustained DMARD-free remission.MethodsWe studied 95 ACPA-positive and/or RF-positive RA patients who achieved DMARD-free remission after median 4.8 years and kept this status for the remaining follow-up (median 4.2 years). Additionally, 21 autoantibody-positive RA patients with a late flare, defined as recurrence of clinical synovitis after a DMARD-free status of ≥1 year, and 45 autoantibody-positive RA patients who were unable to stop DMARD therapy (during median 10 years) were studied. Anti-cyclic citrullinated peptide 2 (anti-CCP2) IgG, IgM and RF IgM levels were measured in 587 samples obtained at diagnosis, before and after achieving DMARD-free remission.Results13% of anti-CCP2 IgG-positive RA patients had seroreverted when achieving remission. In RA patients with a flare and persistent disease this was 8% and 6%, respectively (p=0.63). For anti-CCP2 IgM and RF IgM, similar results were observed. Evaluating the estimated slope of serially measured levels revealed that RF levels decreased more in patients with than without remission (p<0.001); the course of anti-CCP2 levels was not different (p=0.66).ConclusionsSustained DMARD-free status in autoantibody-positive RA was not paralleled by an increased frequency of reversion to autoantibody negativity. This form of immunological remission may therefore not be a treatment target in patients with classified RA.
