28284716 Th17 and IL-17 Cause Acceleration of Inflammation and Fat Loss by Inducing α(2)-Glycoprot 2017 May Rheumatoid arthritis (RA) is a chronic autoimmune disorder that affects the joints. High-fat diet (HFD) is a risk factor for RA and is related to inflammation but responds minimally to medication. Given the association between HFD and inflammation, it is important to understand the function of inflammation-related T cells in RA with HFD. Collagen-induced arthritis (CIA), a model of RA, was induced in HFD mice by injection of collagen II, and metabolic markers and T cells were analyzed. The metabolic index and IgG assay results were higher in HFD-CIA mice than in nonfat diet-CIA mice. Numbers of inflammation-related T cells and macrophages, such as Th1 and Th17 cells and M1 macrophages, were higher in spleens of HFD-CIA mice. HFD-CIA mice had a high level of α(2)-glycoprotein 1 (Azgp1), a soluble protein that stimulates lipolysis. To examine the association between Azgp1 and Th17 cells, the reciprocal effects of Azgp1 and IL-17 on Th17 differentiation and lipid metabolism were measured. Interestingly, Azgp1 increased the Th17 population of splenocytes. Taken together, our data suggest that the acceleration of fat loss caused by Azgp1 in RA with metabolic syndrome is related to the increase of IL-17. Mice injected with the Azgp1-overexpression vector exhibited more severe CIA compared with the mock vector-injected mice.
28082032 Recommendations for the use of parenteral methotrexate in rheumatic diseases. 2018 May OBJECTIVE: To develop recommendations for the use of parenteral methotrexate (MTX) in rheumatic diseases, mainly rheumatoid arthritis, based on best evidence and experience. METHODS: A group of 21 experts on parenteral MTX use was selected. The coordinator formulated 13 questions about parenteral MTX (indications, efficacy, safety and cost-effectiveness). A systematic review was conducted to answer the questions. Using this information, inclusion and exclusion criteria were established, as were the search strategies (involving Medline, EMBASE and the Cochrane Library). Three different reviewers selected the articles. Evidence tables were created. Abstracts from the European League Against Rheumatism (EULAR) and American College of Rheumatology (ACR) were evaluated. Based on this evidence, the coordinator proposed preliminary recommendations that the experts discussed and voted in a nominal group meeting. The level of evidence and grade of recommendation were established using the Oxford Center for Evidence-Based Medicine and the level of agreement with the Delphi technique (2 rounds). Agreement was established if at least 80% of the experts voted yes (yes/no). RESULTS: Most of the evidence involved rheumatoid arthritis. A total of 13 preliminary recommendations on the use of parenteral MTX were proposed; 11 of them were accepted. Two of the 13 were not voted and are commented on in the main text. CONCLUSIONS: The manuscript aims to solve frequent questions and help in decision-making strategies when treating patients with parenteral MTX.
28245350 Cardiovascular Safety of Tocilizumab Versus Tumor Necrosis Factor Inhibitors in Patients W 2017 Jun OBJECTIVE: While tocilizumab (TCZ) is known to increase low-density lipoprotein (LDL) cholesterol levels, it is unclear whether TCZ increases cardiovascular risk in patients with rheumatoid arthritis (RA). This study was undertaken to compare the cardiovascular risk associated with receiving TCZ versus tumor necrosis factor inhibitors (TNFi). METHODS: To examine comparative cardiovascular safety, we conducted a cohort study of RA patients who newly started TCZ or TNFi using claims data from Medicare, IMS PharMetrics, and MarketScan. All patients were required to have previously used a different TNFi, abatacept, or tofacitinib. The primary outcome measure was a composite cardiovascular end point of hospitalization for myocardial infarction or stroke. TCZ initiators were propensity score matched to TNFi initiators with a variable ratio of 1:3 within each database, controlling for >65 baseline characteristics. A fixed-effects model combined database-specific hazard ratios (HRs). RESULTS: We included 9,218 TCZ initiators propensity score matched to 18,810 TNFi initiators across all 3 databases. The mean age was 72 years in Medicare, 51 in PharMetrics, and 53 in MarketScan. Cardiovascular disease was present at baseline in 14.3% of TCZ initiators and 13.5% of TNFi initiators. During the study period (mean ± SD 0.9 ± 0.7 years; maximum 4.5 years), 125 composite cardiovascular events occurred, resulting in an incidence rate of 0.52 per 100 person-years for TCZ initiators and 0.59 per 100 person-years for TNFi initiators. The risk of cardiovascular events associated with TCZ use versus TNFi use was similar across all 3 databases, with a combined HR of 0.84 (95% confidence interval 0.56-1.26). CONCLUSION: This multi-database population-based cohort study showed no evidence of an increased cardiovascular risk among RA patients who switched from a different biologic drug or tofacitinib to TCZ versus to a TNFi.
27966893 Enhancing PET Signal at Target Tissue in Vivo: Dendritic and Multimeric Tris(hydroxypyridi 2017 Feb 15 Tris(hydroxypyridinone) chelators conjugated to peptides can rapidly complex the positron-emitting isotope gallium-68 ((68)Ga) under mild conditions, and the resulting radiotracers can delineate peptide receptor expression at sites of diseased tissue in vivo. We have synthesized a dendritic bifunctional chelator containing nine 1,6-dimethyl-3-hydroxypyridin-4-one groups (SCN-HP(9)) that can coordinate up to three Ga(3+) ions. This derivative has been conjugated to a trimeric peptide (RGD(3)) containing three peptide groups that target the α(v)β(3) integrin receptor. The resulting dendritic compound, HP(9)-RGD(3), can be radiolabeled in 97% radiochemical yield at a 3-fold higher specific activity than its homologues HP(3)-RGD and HP(3)-RGD(3) that contain only a single metal binding site. PET scanning and biodistribution studies show that [(68)Ga(HP(9)-RGD(3))] demonstrates higher receptor-mediated tumor uptake in animals bearing U87MG tumors that overexpress α(v)β(3) integrin than [(68)Ga(HP(3)-RGD)] and [(68)Ga(HP(3)-RGD(3))]. However, concomitant nontarget organ retention of [(68)Ga(HP(9)-RGD(3))] results in low tumor to nontarget organ contrast in PET images. On the other hand, the trimeric peptide homologue containing a single tris(hydroxypyridinone) chelator, [(68)Ga(HP(3)-RGD(3))], clears nontarget organs and exhibits receptor-mediated uptake in mice bearing tumors and in mice with induced rheumatoid arthritis. PET imaging with [(68)Ga(HP(3)-RGD(3))] enables clear delineation of α(v)β(3) integrin receptor expression in vivo.
28455438 Infusion reactions during infliximab treatment are not associated with IgE anti-infliximab 2017 Jul OBJECTIVES: Controversy exists on the role of IgE antidrug antibodies (IgE-ADA) in infusion reactions (IR) on infliximab treatment, partly due to the lack of a positive control used for assay validation. We sought to (1) develop a robust assay to measure IgE-ADA, including a positive control, (2) determine the association between IgE-ADA and IR and (3) determine the incidence of IgE-ADA in infliximab treated patients. METHODS: A recombinant human IgE anti-infliximab monoclonal antibody was developed as standard and positive control. With this antibody, we set up a novel robust assay to measure IgE-ADA. IgE-ADA was determined in three retrospective cohorts (n=159) containing IR+ (n=37) and IR- (n=39), and longitudinal sera of 83 spondyloarthritis. RESULTS: IgE-ADA was found in 0/39 IR-, whereas 4/37 (11%) IR+ showed low levels (0.1-0.3 IU/mL, below the 0.35 IU/mL threshold associated with elevated risk of allergic symptoms). All patients who were IgE-ADA positive also had (very) high IgG-ADA levels. The incidence of IgE-ADA in patients with infliximab-treated spondyloarthritis was estimated at less than approximately 1%. CONCLUSIONS: IgE-ADA is rarely detected in infliximab-treated patients. Moreover, the absence of IgE-ADA in the majority of IR+ patients suggests that IgE-ADA is not associated with infusion reactions.
28384040 CTLA-4 +49 G/A Polymorphism Confers Autoimmune Disease Risk: An Updated Meta-Analysis. 2017 Apr BACKGROUND: Cytotoxic T lymphocyte antigen-4 (CTLA-4) plays a pivotal role in immune homeostasis. Dysregulated expression of CTLA-4 leads to many autoimmune diseases, including rheumatoid arthritis, systemic lupus erythematosus, and type 1 diabetes (T1D). There has been a controversial association between the CTLA-4 +49 G/A SNP (rs231775) and autoimmune diseases. Therefore, this meta-analysis was performed to assess the link between rs231775 and autoimmune disease risk. MATERIALS AND METHODS: We retrieved the available studies from PUBMED and EMBASE through February, 2016 and then performed meta-analyses that included all populations, as well as by ethnicity. RESULTS: After evaluating data from 4732 patients and 6270 healthy controls that included both Caucasian and Asian ethnicities, we found that rs231775 is strongly associated with autoimmune disease incidence in a homozygote comparison (GG vs. AA, 95% confidence interval [95% CI] 1.382-2.401), in a heterozygote comparison (AG vs. AA, 95% CI 1.151-1.611), in an allelic model (T allele vs. G allele, 95% CI 1.109-1.441), in a dominant model (GG/AG vs. AA, 95% CI 1.220-1.787), and in a recessive model (GG vs. AA/AG, 95% CI 1.128-1.661). The OR (odds ratio) from all models suggested a very significant association between rs231775 and autoimmune diseases. CONCLUSION: Our present study indicates that CTLA-4 +49 G/A (rs231775) is associated with the susceptibility of autoimmune disease. Hence, rs231775 might be utilized as a diagnostic biomarker in both Asian and Caucasian populations.
28027038 Effectiveness of Occupational Therapy Interventions for Adults With Musculoskeletal Condit 2017 Jan/Feb Occupational therapy practitioners are key health care providers for people with musculoskeletal disorders of the distal upper extremity. It is imperative that practitioners understand the most effective and efficient means for remediating impairments and supporting clients in progressing to independence in purposeful occupations. This systematic review provides an update to a previous review by summarizing articles published between 2006 and July 2014 related to the focused question, What is the evidence for the effect of occupational therapy interventions on functional outcomes for adults with musculoskeletal disorders of the forearm, wrist, and hand? A total of 59 articles were reviewed. Evidence for interventions was synthesized by condition within bone, joint, and general hand disorders; peripheral nerve disorders; and tendon disorders. The strongest evidence supports postsurgical early active motion protocols and splinting for various conditions. Very few studies have examined occupation-based interventions. Implications for occupational therapy practice and research are provided.
28654766 Methotrexate-Related Lymphoproliferative Disorder in Patients With Osteonecrosis of the Ja 2018 Jan Patients with immunodeficiency or immunosuppression are at risk of developing a lymphoproliferative disorder (LPD). Methotrexate (MTX) is an iatrogenic cause of LPD, which in up to 50% cases occurs in extranodal sites. The occurrence of MTX-related LPD with osteonecrosis of the jaw (ONJ) has rarely been reported. Moreover, there are no clear diagnostic criteria and treatment strategies for management of these lesions. In the present cases, discontinuing MTX and debridement of the necrotic bone were effective. This report describes 3 cases of MTX-related LPD in patients with longstanding rheumatoid arthritis (RA) who presented with ONJ. The first patient was a 74-year-old man with RA who had received treatment with MTX for 7 years before presenting with ONJ and submental lymphadenopathy. The second patient was a 79-year-old woman who had been treated for 21 years with MTX and who presented with ONJ. The third patient was a 67-year-old man who had been treated with MTX for more than 15 years. In all 3 cases, biopsy, histology, and immunohistochemistry using a panel of lymphoid markers (Epstein-Barr virus [EBV], CD79a, CD20, PAX-5, CD3, and CD30) resulted in the diagnosis of EBV-driven T-cell, B-cell, and Hodgkin-like LPD. All 3 patients recovered after cessation of MTX and surgical debridement. Biopsy examination, diagnostic immunohistochemistry using lymphoid immune markers, and imaging studies using computed tomography, magnetic resonance imaging, and positron-emission tomographic computed tomography were useful for the correct diagnosis of this condition.
28542869 Tanshinone IIA ameliorates chronic arthritis in mice by modulating neutrophil activities. 2017 Oct Rheumatoid arthritis (RA) is a chronic immune inflammatory disease mediated by the influx of immune cells into the synovial joint space. As Tanshinone IIA (TIIA) has potent anti-oxidant and anti-inflammatory activities, we used the adjuvant-induced arthritis (AA) murine model of RA to investigate the impact of TIIA on RA and immune cell activation. The anti-arthritic activity of TIIA was investigated in an adjuvant-induced arthritis model of RA in mice. Myeloperoxidase and neutrophil elastase expression levels were assessed in ankle joints by immunohistochemistry analysis. Immune cell infiltration was evaluated in air pouch experiments. Proinflammatory cytokines expression levels were determined by quantitative real-time polymerase chain reaction (PCR) and enzyme-linked immunosorbent assays. Neutrophil extracellular traps (NETs) were assessed by immunostaining and confocal microscopy. Treatment with TIIA alleviated cartilage erosion and neutrophil infiltration in the ankle joints of AA mice and reduced proinflammatory cytokine expression levels in sera. TIIA suppressed interleukin-6 and tumour necrosis factor-α expression and release in neutrophils and promoted neutrophil apoptosis. TIIA also inhibited the NET formation of neutrophils. Our findings demonstrated that TIIA can ameliorate RA effectively by targeting neutrophils, indicating that TIIA may act as a potential therapeutic for RA.
28760953 CD318 is a ligand for CD6. 2017 Aug 15 It has been proposed that CD6, an important regulator of T cells, functions by interacting with its currently identified ligand, CD166, but studies performed during the treatment of autoimmune conditions suggest that the CD6-CD166 interaction might not account for important functions of CD6 in autoimmune diseases. The antigen recognized by mAb 3A11 has been proposed as a new CD6 ligand distinct from CD166, yet the identity of it is hitherto unknown. We have identified this CD6 ligand as CD318, a cell surface protein previously found to be present on various epithelial cells and many tumor cells. We found that, like CD6 knockout (KO) mice, CD318 KO mice are also protected in experimental autoimmune encephalomyelitis. In humans, we found that CD318 is highly expressed in synovial tissues and participates in CD6-dependent adhesion of T cells to synovial fibroblasts. In addition, soluble CD318 is chemoattractive to T cells and levels of soluble CD318 are selectively and significantly elevated in the synovial fluid from patients with rheumatoid arthritis and juvenile inflammatory arthritis. These results establish CD318 as a ligand of CD6 and a potential target for the diagnosis and treatment of autoimmune diseases such as multiple sclerosis and inflammatory arthritis.
28699378 Reasons for cesarean and medically indicated deliveries in pregnancies in women with syste 2018 Mar Objective To determine reasons for cesarean and medically indicated deliveries in a registry of pregnant women with SLE compared to RA. Methods Pregnant women with SLE or RA were prospectively followed, and pregnancy outcomes were collected, including whether labor was spontaneous or medically indicated and delivery was vaginal or cesarean. Preterm birth was defined as a birth <37 weeks gestation. Differences in reasons for cesarean delivery and indication of delivery between term and preterm births were determined by Fisher's exact test. Results Compared to RA pregnancies, SLE pregnancies had modestly higher rates of preterm birth (24% SLE vs 14% RA), pre-eclampsia (15% SLE vs 7% RA), and cesarean delivery (48% SLE vs 30% RA). The majority of preterm births among women with SLE were indicated (70%), most commonly for pre-eclampsia or the health of the infant or mother. The majority of preterm births among women with RA, however, were spontaneous, primarily due to premature rupture of membranes. Conclusion Pre-eclampsia and maternal SLE activity appear to be the key drivers for the high rate of preterm birth and medically indicated delivery in SLE. This contrasts with RA, where preterm labor is most often due to spontaneous onset of labor.
28736929 Impact of Cost-Sharing Increases on Continuity of Specialty Drug Use: A Quasi-Experimental 2018 Aug OBJECTIVE: To examine the impact of cost-sharing increases on continuity of specialty drug use in Medicare beneficiaries with multiple sclerosis (MS) or rheumatoid arthritis (RA). DATA SOURCES/STUDY SETTING: Five percent Medicare claims data (2007-2010). STUDY DESIGN: Quasi-experimental study examining changes in specialty drug use among a group of Medicare Part D beneficiaries without low-income subsidies (non-LIS) as they transitioned from a 5 percent cost-sharing preperiod to a ≥25 percent cost-sharing postperiod, as compared to changes among a disease-matched contemporaneous control group of patients eligible for full low-income subsidies (LIS), who faced minor cost sharing (≤$6.30 copayment) in both the pre- and postperiods. DATA COLLECTION/EXTRACTION METHODS: Key variables were extracted from Medicare data. PRINCIPAL FINDINGS: Relative to the LIS group, the non-LIS group had a greater increase in incidence of 30-day continuous gaps in any Part D treatment from the lower cost-sharing period to the higher cost-sharing period (MS, absolute increase = 10.1 percent, OR = 1.61, 95% CI 1.19-2.17; RA, absolute increase = 21.9 percent, OR = 2.75, 95% CI 2.15-3.51). The increase in Part D treatment gaps was not offset by increased Part B specialty drug use. CONCLUSIONS: Cost-sharing increases due to specialty tier-level cost sharing were associated with interruptions in MS and RA specialty drug treatments.
29288042 STAT3 mutation and its clinical and histopathologic correlation in T-cell large granular l 2018 Mar Although T-cell large granular lymphocytic leukemia (T-LGLL) is a clinically indolent disorder, patients with moderate to severe cytopenia require therapeutic intervention. The recent discovery of STAT3 mutations has shed light on the genetic basis of T-LGLL pathogenesis. However, the association of STAT3 mutational status with patients' clinical, histopathologic, and other laboratory features has not been thoroughly evaluated in T-LGLL. In this study, STAT3 mutations were identified in 18 of 36 patients with T-LGLL (50%), including Y640F (12/18, 66.7%), N647I (3/18, 16.7%), E638Q (1/18, 5.6%), I659L (1/18, 5.6%), and K657R (1/18, 5.6%). Interestingly, pure red cell aplasia was seen exclusively in T-LGLL patients without STAT3 mutations (6/15 in the wild-type STAT3 group versus 0/13 in the mutant STAT3 group; P = .02); these patients also were the only responders to T-LGLL therapy (mainly cyclophosphamide) in wild-type STAT3 group. Patients harboring STAT3 mutations were more prone to rheumatoid arthritis (4/13 versus 0/15 in the wild-type STAT3 group; P = .04), frequently requiring therapy for neutropenia/neutropenia-associated infections, and demonstrated good therapeutic responses to methotrexate. No significant differences were seen in complete blood count, flow cytometric immunophenotypic features, T-cell receptor γ V-J rearrangement repertoire, and bone marrow biopsy morphology among the STAT3-mutation and wild-type groups other than significantly larger tumor burden in patients with STAT3 mutations. The distinct disease association and therapeutic responses observed in patients with mutant and wild-type STAT3 warrant further investigation to elucidate the underlying mechanisms. They also highlight the importance of identifying STAT3 mutational status in patients with T-LGLL, which may aid in clinical therapeutic choice.
28535619 Prevalence and incidence of osteoporotic fractures in patients on long-term glucocorticoid 2017 May 22 Osteoporosis and fractures are common and invalidating consequences of chronic glucorticoid (GC) treatment. Reliable information regarding the epidemiology of GC induced osteoporosis (GIOP) comes exclusively from the placebo group of randomized clinical trials while observational studies are generally lacking data on the real prevalence of vertebral fractures, GC dosage and primary diagnosis. The objective of this study was to evaluate the prevalence and incidence of osteoporotic fractures and to identify their major determinants (primary disease, GC dosage, bone mineral density, risk factors, specific treatment for GIOP) in a large cohort of consecutive patients aged >21 years, on chronic treatment with GC (≥5 mg prednisone - PN - equivalent) and attending rheumatology centers located all over Italy. Glucocorticoid Induced OsTeoporosis TOol (GIOTTO) is a national multicenter cross-sectional and longitudinal observational study. 553 patients suffering from Rheumatoid Arthritis (RA), Polymyalgia Rheumatica (PMR) and Connective Tissue Diseases (CTDs) and in chronic treatment with GCs were enrolled. Osteoporotic BMD values (T score <-2.5) were observed in 28%, 38% and 35% of patients with CTDs, PMR or RA at the lumbar spine, and in 18%, 29% and 26% at the femoral neck, respectively. Before GC treatment, prevalent clinical fractures were reported by 12%, 37% and 17% of patients with CTDs, PMR, or RA, respectively. New clinical fragility fractures during GC treatment were reported by 12%, 10% and 23% of CTDs, PMR and RA patients, respectively. Vertebral fractures were the prevailing type of fragility fracture. More than 30% of patients had recurrence of fracture. An average of 80% of patients were in supplementation with calcium and/or vitamin D during treatment with GCs. Respectively, 64%, 80%, and 72% of the CTDs, PMR and RA patients were on pharmacological treatment for GIOP, almost exclusively with bisphosphonates. The GIOTTO study might provide relevant contributions to clinical practice, in particular by highlighting and quantifying in real life the prevalence of GIOP and relative fractures, the frequency of the main risk factors, and the currently sub-optimal prevention. Moreover, these results emphasize the importance of the underlying rheumatic disease on the risk of GIOP associated fractures.
28619978 Rheumatoid arthritis causing diffuse alveolar haemorrhage: a novel therapeutic approach. 2017 Jun 14 Pulmonary vascular involvement due to rheumatoid arthritis, presenting as diffuse alveolar haemorrhage (DAH), is a rare phenomenon, especially if there are no signs of systemic vasculitides. Furthermore, how to proceed with the management of these patients is challenging, as in the case of our patient, who had recurrent DAH. We present a case of a patient with known rheumatoid arthritis who had recurrence of DAH that spanned over several years, often presenting with life-threatening respiratory failure. While her DAH presentation improved with high-dose glucocorticoids, to resolve her recurrence, we opted to initiate treatment with rituximab, with a short course of azathioprine. After the second round of rituximab, the patient continues to do well without any further DAH-related complications. We also summarise prior cases of such patients to highlight variable treatment options.
29054755 Association of polymorphic variants in IL1B gene with secretion of IL-1β protein and infl 2018 Jan 30 The proinflammatory cytokine interleukin-1beta (IL-1β) is a key mediator of inflammation which affects cell proliferation and differentiation. IL-1β is considered to contribute to the pathophysiology of rheumatoid arthritis (RA). Polymorphisms in cytokine genes are highly influenced by ethnicity. Hence, in this study polymorphism of the IL1B-511(C/T) within promoter region was analyzed by using polymerase chain reaction-restriction fragment length Polymorphism (PCR-RFLP) in 187 RA patients and 214 controls. The prevalence of different genotypes and allelic frequency distribution was compared in RA patients and controls. Levels of inflammatory markers and serum levels of IL-1β were estimated by ELISA The serum inflammatory markers levels were significantly higher in RA patients as compared to controls (RF=127.3±21.3U/mL, Anti-CCP=17.8±8.3U/mL, CRP=17.86±7.1mg/L and IL-1β=21.25±4.19pg/mL in RA patients p<0.01). The frequency of heterozygous mutant (C/T) and homozygous mutant (T/T) variants were significantly higher in RA patients as compared to controls and the odds ratios by logistic regression were (OR=2.2, p<0.001) and (OR=3.21, p<0.01) respectively. The association persisted on combining the heterozygous mutant and homozygous mutant (CT+TT) together as compared to controls (OR=2.39; p<0.001). Positive and significant (p<0.05) correlation of circulating IL-1β levels with RF (r=0.232), anti-CCP (r=0.207) and CRP (r=0.166) among RA patients were found. The levels of anti-CCP were significantly higher in homozygous mutant variants (TT) as well as the heterozygous mutant variants (C/T) in comparison to the wild variants (CC) (p<0.01). The results of this study reveal that mutant allele (T) of IL1B-511 promoter SNP tends to be associated with elevated anti-CCP and IL-1β levels as observed in RA patients and hence disease susceptibility.
28264816 EULAR recommendations for the management of rheumatoid arthritis with synthetic and biolog 2017 Jun 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). Monotherapy, combination therapy, treatment strategies (treat-to-target) and the targets of sustained clinical remission (as defined by the American College of Rheumatology-(ACR)-EULAR Boolean or index criteria) or low disease activity are discussed. Cost aspects were taken into consideration. As first strategy, the Task Force recommends MTX (rapid escalation to 25 mg/week) plus short-term GC, aiming at >50% improvement within 3 and target attainment within 6 months. If this fails stratification is recommended. Without unfavourable prognostic markers, switching to-or adding-another csDMARDs (plus short-term GC) is suggested. In the presence of unfavourable prognostic markers (autoantibodies, high disease activity, early erosions, failure of 2 csDMARDs), any bDMARD (current practice) or Jak-inhibitor should be added to the csDMARD. If this fails, any other bDMARD or tsDMARD is recommended. If a patient is in sustained remission, bDMARDs can be tapered. For each recommendation, levels of evidence and Task Force agreement are provided, both mostly very high. These recommendations intend informing rheumatologists, patients, national rheumatology societies, hospital officials, social security agencies and regulators about EULAR's most recent consensus on the management of RA, aimed at attaining best outcomes with current therapies.
29020251 Differential blood pressure effects of ibuprofen, naproxen, and celecoxib in patients with 2017 Nov 21 AIMS: Non-steroidal anti-inflammatory drugs (NSAIDs), both non-selective and selective cyclooxygenase-2 (COX-2) inhibitors, are among the most widely prescribed drugs worldwide, but associate with increased blood pressure (BP) and adverse cardiovascular (CV) events. PRECISION-ABPM, a substudy of PRECISION was conducted at 60 sites, to determine BP effects of the selective COX-2 inhibitor celecoxib vs. the non-selective NSAIDs naproxen and ibuprofen. METHODS AND RESULTS: In this double-blind, randomized, multicentre non-inferiority CV-safety trial, 444 patients (mean age 62 ± 10 years, 54% female) with osteoarthritis (92%) or rheumatoid arthritis (8%) and evidence of or at increased risk for coronary artery disease received celecoxib (100-200 mg bid), ibuprofen (600-800 mg tid), or naproxen (375-500 mg bid) with matching placebos in a 1: 1: 1 allocation, to assess the effect on 24-h ambulatory BP after 4 months. The change in mean 24-h systolic BP (SBP) in celecoxib, ibuprofen and naproxen-treated patients was -0.3 mmHg [95% confidence interval (CI), -2.25, 1.74], 3.7 (95% CI, 1.72, 5.58) and 1.6 mmHg (95% CI, -0.40, 3.57), respectively. These changes resulted in a difference of - 3.9 mmHg (P = 0.0009) between celecoxib and ibuprofen, of - 1.8 mmHg (P = 0.12) between celecoxib and naproxen, and of - 2.1 mmHg (P = 0.08) between naproxen and ibuprofen. The percentage of patients with normal baseline BP who developed hypertension (mean 24-h SBP ≥ 130 and/or diastolic BP ≥ 80 mmHg) was 23.2% for ibuprofen, 19.0% for naproxen, and 10.3% for celecoxib (odds ratio 0.39, P = 0.004 and odds ratio 0.49, P = 0.03 vs. ibuprofen and naproxen, respectively). CONCLUSIONS: In PRECISION-ABPM, allocation to the non-selective NSAID ibuprofen, compared with the COX-2 selective inhibitor celecoxib was associated with a significant increase of SBP, and a higher incidence of new-onset hypertension. CLINICALTRIALS: gov number NCT00346216.
28594861 Level of inflammatory cytokines in rheumatoid arthritis patients: Correlation with 25-hydr 2017 BACKGROUND: Rheumatoid arthritis (RA) is an autoimmune inflammatory disorder. Reactive oxygen species (ROS) and pro-inflammatory cytokines have been believed to be involved in the etiopathogenesis of the disease. The aim of the study was to determine the correlation of inflammatory cytokines with 25-hydroxy vitamin D and ROS. METHODS: 100 RA patients and 50 healthy age and sex matched individuals were included in the study. Patients were further divided on the basis of presence or absence of rheumatoid factor and disease severity. Serum 25-hydroxy vitamin D levels were monitored by chemiluminescent immunoassay. 10% hematocrit was used to detect the level of ROS by spectro fluorometer. The levels of inflammatory cytokines (TNF-α, IL-1β, IL-6, IL-10 and IL-17) were determined in plasma by ELISA. RESULTS: The level of 25-hydroxy vitamin D was found to be decreased in RA patients in comparison to the control group. However the level of ROS and inflammatory cytokines were found to be elevated in RA patients in comparison with the healthy controls, with the increase being more pronounced in seropositive and RA patients having high disease severity. Inflammatory cytokines showed negative correlation with 25-hydroxy vitamin D and positive correlation with ROS. CONCLUSION: This study for the first time shows the association of inflammatory cytokines with 25-hydroxy vitamin D and ROS in RA patients. The results suggest that 25-hydroxy vitamin D being an immune modulator is decreased in the serum of RA patients. Further ROS and cytokines play an important role in the pathogenesis of RA and are responsible for increasing the severity of disease.
28602866 Evaluation of cardiovascular risk associated with SKI306X use in patients with osteoarthri 2017 Jul 31 ETHNOPHARMACOLOGICAL RELEVANCE: SKI306X (Joins(®)) is an anti-inflammatory analgesic herbal medicine extract that was clinically approved for treatment of osteoarthritis in the previous trials and shown to be effective on follow-up studies. However, its potential cardiovascular risk has yet to be investigated. AIM OF THE STUDY: This retrospective cohort study investigated the cardiovascular safety of SKI306X, celecoxib and naproxen. MATERIALS AND METHODS: We used the National Health Insurance Service-National Sample Cohort (NHIS-NSC) to investigate patients over 20 years old with osteoarthritis and rheumatoid arthritis who received a single prescription of SKI306X, celecoxib or naproxen at least once from January 1, 2011 through December 31, 2012. Patients who received SKI306X, celecoxib or naproxen from January 1, 2009 to December 31, 2010 were excluded. Data pertaining to the included patients were investigated to determine the risk of major cardiovascular events associated with the aforementioned prescription using the Cox proportional hazards model after being adjusted for sex, age and comorbidity. RESULTS: A total of 27,253 patients were selected, among which 10,983 were prescribed SKI306X, 12,311 celecoxib and 3959 naproxen. The incidence of major cardiovascular events was highest for celecoxib (15.4%), followed by SKI306X (8.6%) and naproxen (8.0%). Celecoxib had a higher cardiovascular risk than naproxen, while SKI306X did not have a higher risk of cardiovascular events than naproxen. Upon sensitivity analysis, SKI306X was associated with 1.36 times (95%CI: 1.08-1.72) more cardiovascular events than naproxen during 15-60 days of prescription, but not at less than 14 days or more than 61 days. CONCLUSIONS: Evaluation of the cardiovascular safety of the anti-inflammatory analgesic herbal medicine SKI306X revealed that it did not differ from that of naproxen, which is known to have low cardiovascular risk.
