Background: Use of tumor necrosis factor inhibitors (TNFi) in patients with a history of cancer remains a clinical dilemma. Objective: To investigate whether TNFi treatment in rheumatoid arthritis (RA) is associated with increased risk for cancer recurrence. Design: Population-based cohort study based on linkage of nationwide registers. Setting: Sweden. Participants: Patients with RA who started TNFi treatment between 2001 and 2015, after being diagnosed with cancer, and matched patients with RA and a history of the same cancer who had never received biologics...

Sjögren's syndrome (pSS) is a complex and heterogeneous disorder characterized by different clinical subsets. Recently, great efforts have been made searching for reliable biomarkers able to ameliorate the diagnostic algorithm and the prognostic stratification of pSS patients and ultimately allowing the scientific community to address some of the unmet needs for the disease. In this review, we have summarized the state of the art of 'traditional' widely acknowledged clinical, serological and histologic biomarkers for pSS with the aim of highlighting their relevance and limitations in clinical practice...

RATIONALE: Primary cutaneous amyloidosis (PCA) is a localized skin disorder characterized by the abnormal deposition of amyloid in the extracellular matrix of the dermis. The association between PCA and other diseases, although rare, has been documented for various autoimmune diseases. PCA associated with autoimmune hepatitis-primary biliary cirrhosis (AIH-PBC) overlap syndrome and Sjögren syndrome (SS) has not been previously reported in the literature. PATIENT CONCERNS: A 50-year-old woman presented with progressive abnormal liver enzyme levels and was referred to our department...

Primary Sjögren syndrome (pSS) is a prototypical autoimmune disease. The involvement of B cells in the pathogenesis of pSS has long been suspected on the basis of clinical observations that include the presence of serum autoantibodies, hypergammaglobulinaemia, increased levels of free light chains and increased risk of B cell lymphoma. Moreover, the composition of the B cell subset is altered in pSS. In this Review, we discuss the mechanisms that support the increased activation of B cells in pSS, including genetic and epigenetic factors and environmental triggers that promote B cell activation via the innate immune system...

OBJECTIVE: EMBODY 1 (ClinicalTrials.gov identifier: NCT01262365) and EMBODY 2 (ClinicalTrials.gov identifier: NCT01261793) investigated the efficacy and safety of epratuzumab, a CD22-targeted humanized monoclonal IgG antibody, in patients with systemic lupus erythematosus (SLE). The studies showed no significant difference from placebo in primary or secondary clinical outcome measures but did demonstrate B cell-specific immunologic activity. The aim of this post hoc analysis was to determine whether epratuzumab had a different clinical efficacy profile in SLE patients with versus those without an associated diagnosis of Sjögren's syndrome (SS)...

BACKGROUND: Limited studies have explored the relationship between air pollution and rheumatoid arthritis (RA), with the results being somewhat inconsistent. METHODS: This was a retrospective cohort study that included 322,301 subjects aged 30-50 years, selected from the National Health Insurance Research Database in Taiwan, were followed from 2001 to 2010. We used a time-dependent extended Cox model and incorporated time-dependent variables to estimate the associations between the annual mean concentrations of air pollutants with RA, including carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), particles with an aerodynamic diameter less than 10 μm (PM10), and sulfur dioxide (SO2), and reported the hazard ratio (HR) and 95% confidence interval (CI)...

Increased effectiveness of pharmacological treatments in early RA has led many to believe that difficult-to-treat, established RA is a condition of the past. However, there are still plenty of RA patients who continue to have signs and symptoms suggestive of inflammatory disease activity, despite consecutive treatment with multiple conventional synthetic and biological DMARDs. We argue that difficult-to-treat RA constitutes an area of unmet clinical need and propose a definition of this concept. An overview of what is known about the multiple contributory factors varying for each individual patient, and an approach towards improved patient-tailored management are presented...

Patients with rheumatoid arthritis (RA) have increased oxidative stress, decreased antioxidant levels, and impaired antioxidant capacity. Cold treatments are used to relieve joint inflammation and pain. Therefore, we measured the effect of cold treatments on the antioxidative capacity of RA patients with active disease. Sixty patients were randomized to (1) whole body cryotherapy at -110 °C, (2) whole body cryotherapy at -60 °C, or (3) local cryotherapy. Each treatment was given three times daily for 7 consecutive days in addition to the conventional rehabilitation...

OBJECTIVE: To develop recommendations for prevention and treatment of glucocorticoid-induced osteoporosis (GIOP). METHODS: We conducted a systematic review to synthesize the evidence for the benefits and harms of GIOP prevention and treatment options. The Grading of Recommendations Assessment, Development and Evaluation methodology was used to rate the quality of evidence. We used a group consensus process to determine the final recommendations and grade their strength...

OBJECTIVES: In the second Computer-Assisted Management in Early Rheumatoid Arthritis trial, patients had started with methotrexate and 10 mg prednisone (MTX+pred) or placebo (MTX+plac). After the trial, prednisone was tapered and stopped, if possible. The objective was to compare, during the post-trial follow-up between the two former strategy groups, initiation of the first biological disease-modifying antirheumatic drug (bDMARD), radiographic outcome and onset of glucocorticoid (GC)-related comorbidities...

OBJECTIVES: To study the prevalence of remission and its effect on damage and quality of life (QOL) in Chinese patients with systemic lupus erythematosus (SLE). METHODS: Patients who fulfilled ≥4 American College of Rheumatology criteria for SLE were identified. Their remission status at last clinic visits was determined by the European consensus criteria (complete/clinical remission ± immunosuppressive drugs). The increase in SLE damage index (SDI) in the preceding 5 years was compared between patients who were and were not in remission for ≥5 years...

Systemic lupus erythematosus is associated with accelerated atherosclerosis and increased risk of cardiovascular complications. The aim of this study was to review the effectiveness of interventions for primary and secondary prevention of cardiovascular events and mortality and to review the effectiveness of interventions for cardiovascular risk factor reduction in systemic lupus erythematosus patients. A systematic review was conducted. Electronic databases Medline and Embase (1961-2015) were searched. Nineteen articles met the inclusion criteria and were selected...

The association of primary Sjögren's syndrome (pSS) with Major Histocompatibility Complex (MHC) alleles is quintessential of MHC-disease associations. Indeed, although disease associations with classical HLA class I and II alleles/haplotypes are amply documented, further dissection is often prevented by the strong linkage disequilibrium across the entire MHC complex. Here we study the association of pSS, not with HLA genes, but with the non-conventional MHC encoded class I gene, MICA (MHC class I chain-related gene A)...

OBJECTIVES: To compare the performance of the new 2016 American College of Rheumatology (ACR)-European League Against Rheumatism (EULAR) classification criteria for primary Sjögren's syndrome (SS) with 1999 revised Japanese Ministry of Health criteria for diagnosis of SS (JPN), 2002 American-European Consensus Group classification criteria for SS (AECG) and 2012 ACR classification criteria for SS (ACR) in Japanese patients. METHODS: The study subjects were 499 patients with primary SS (pSS) or suspected pSS who were followed up in June 2012 at 10 hospitals in Japan...

OBJECTIVES: Jaccoud's arthropathy (JA) is a deforming, non-erosive arthritis, occurring in 2-35% of systemic lupus erythematosus (SLE) patients. We aimed to evaluate JA patients in a wide monocentric SLE cohort in terms of clinical, serological and ultrasonographic features. METHODS: Consecutive SLE patients (ACR criteria 1997) were evaluated. The JA index was applied for patients with reducible deformities. Patients with a JA index ≥5 underwent physical examination, blood testing and ultrasound (US) assessment...

OBJECTIVE: To estimate the future risk and time trends of venous thromboembolism (VTE) in individuals with newly diagnosed primary Sjögren syndrome (pSS) in the general population. METHODS: Using a population database that includes all residents of British Columbia, Canada, we created a study cohort of all patients with incident SS and up to 10 controls from the general population matched for age, sex, and entry time. We compared incidence rates (IR) of pulmonary embolism (PE), deep vein thrombosis (DVT), and VTE between the 2 groups according to SS disease duration...

TNF blockers are highly efficacious at dampening inflammation and reducing symptoms in rheumatic diseases such as rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis, and also in nonrheumatic syndromes such as inflammatory bowel disease. As TNF belongs to a superfamily of 19 structurally related proteins that have both proinflammatory and anti-inflammatory activity, reagents that disrupt the interaction between proinflammatory TNF family cytokines and their receptors, or agonize the anti-inflammatory receptors, are being considered for the treatment of rheumatic diseases...

OBJECTIVE: Persistent pruritic eruptions (PPE) are common among our patients with adult-onset Still disease (AOSD). We aimed to characterize the clinicopathologic features of the AOSD-associated evanescent and persistent rashes. METHODS: We reviewed the clinicopathologic features of the skin lesions from all AOSD cases diagnosed in our hospital during 1988 to 2009. The diagnoses were based on Yamaguchi criteria for AOSD. RESULTS: Altogether, there were 36 patients (6 men and 30 women) with age of onset ranging from 17 to 67 years (average 35...

Typical skin rash, which appears and disappears along with respective rise and fall of fever, is well-known, and included as one of the major criteria of adult-onset Still's disease (AOSD) (Yamaguchi's criteria). In addition, various skin lesions are occasionally observed in association with AOSD. Persistent pruritic eruptions present with some clinical features, such as urticarial erythema, flagellate erythema, erythematous, slightly scaly or crusted papules, and/or plaques on the trunk and extremities. These lesions show unique histological features such as dyskeratosis with a peculiar, distinctive distribution in the upper epidermis and cornified layers with focal hyperkeratosis...
