30233261 Low mortality rate in Italian rheumatoid arthritis patients from a tertiary center: putati 2018 BACKGROUND AND OBJECTIVE: Anti-carbamylated protein antibodies (anti-CarP Ab) represent a novel kind of autoantibodies specificity detectable in the sera of patients with rheumatoid arthritis (RA). They have been recently reported to be associated with increased mortality in Spanish patients with RA. The aim of our study was to compare the incidence mortality rates (IMRs) detected in RA patients from a tertiary Italian center with those reported in other European tertiary centers and to evaluate the putative role of anti-CarP Ab in modulating the low IMR detected in our patients. METHODS: Clinical charts of patients consecutively admitted to our center, from January 1, 2008, to December 31, 2014, were retrospectively reviewed. The mortality rate (expressed as the number of deaths in the cohort divided by the number of years of IMR follow-up) and causes of death were assessed at December 31, 2015. Sera of 61 patients, representative of the whole cohort, collected at the time of admission to our center were investigated for the presence and the level of anti-CarP Ab. Demographic and clinical features, mortality rates and prevalence of anti-CarP Ab in our series were compared with those reported in other European cohorts. RESULTS: We observed 608 patients for a median of 3.51 years. All-cause and cause-specific IMRs in our cohort were significantly lower than the Better Anti-rheumatic Farmaco-therapy and the Spanish cohort, while only all-cause and cardiovascular IMRs were significantly lower in our series with respect to the Leiden Early Arthritis Clinic cohort. Anti-CarP Ab prevalence was significantly lower in our series than in any other European cohorts. CONCLUSION: We confirm that the mortality rate is lower in our Italian RA cohort with respect to other European cohorts. Whether the low prevalence of anti-CarP Ab might be responsible for this result awaits to be furtherly investigated.
30281626 Systemic treatment with resveratrol reduces the progression of experimental periodontitis 2018 Rheumatoid arthritis and periodontitis are chronic inflammatory diseases which has been closely associated due to the nature of immune-inflammatory imbalance response. Resveratrol is a naturall product with biological proprieties that may promote immunomodulatory effects on host response. This study investigated resveratrol continuous administration effect on experimental periodontitis and arthritis progression in rats. Thirty-five rats were assigned to the following groups: 1-experimental arthritis + experimental periodontitis + placebo (RA+EP +PL) (n = 12); 2 -RA+EP+ ibuprofen (RA+PE+IB) (n = 11); 3-RA+EP+ resveratrol (RA+PE+RSV) (n = 11). After euthanasia, the specimens were processed for morphometric analysis of bone loss, and the gingival tissue surrounding the first molar was collected for quantification of inflammatory markers using a Luminex/MAGpix assay and anti-citrullinated protein antibody (ACCPA) levels were measured by ELISA assay. Serum level of rheumatoid factor (RF) was measured by ELISA assay. Paw edema was analyzed using a plethysmometer. Higher bone loss was observed in PL group, when compared to IB and RSV groups. RSV group presented higher IL-4 concentration than PL and IB groups. Resveratrol reduced RF serum levels and both IB and RSV decreased ACCPA gingival levels. Besides, paw swelling level was significantly lower in IB and RSV groups in the 21th day and only in RSV group in the 28th day. Histological analyzes showed smooth articular surface and higher width of the subchondral cortical in RSV group. Resveratrol showed modulatory effect and seems to reduce the inflammatory signs of arthritis and articular damage throughout the time.
30160792 Ferulic acid inhibits interleukin 17-dependent expression of nodal pathogenic mediators in 2018 Aug 30 Interleukin 17 (IL-17), a proinflammatory cytokine produced by T helper (Th) 17 cells, potentially controls fibroblast-like synoviocytes (FLS)-mediated disease activity of rheumatoid arthritis (RA) via IL-17/ IL-17 receptor type A (IL-17RA)/signal transducer and activator of transcription 3 (STAT-3) signaling cascade. This has suggested that targeting IL-17 signaling could serve as an important strategy to treat FLS-mediated RA progression. Ferulic acid (FA), a key polyphenol, attenuates the development of gouty arthritis and cancer through its anti-inflammatory effects, but its therapeutic efficiency on IL-17 signaling in FLS-mediated RA pathogenesis remains unknown. In the current study, FA markedly inhibited the IL-17-mediated expression of its specific transmembrane receptor IL-17RA in FLS isolated from adjuvant-induced arthritis (AA) rats. Importantly, FA dramatically suppressed the IL-17-mediated expression of toll-like receptor 3 (TLR-3), cysteine-rich angiogenic inducer 61 (Cyr61), IL-23, granulocyte-macrophage colony stimulating factor (GM-CSF) in AA-FLS via the inhibition of IL-17/IL-17RA/STAT-3 signaling cascade. In addition, FA significantly decreased the formation of osteoclast cells and bone resorption potential in a coculture system consisting of IL-17 treated AA-FLS and rat bone marrow derived monocytes/macrophages. Furthermore, FA remarkably inhibited the IL-17-mediated expression of receptor activator of nuclear factor κ-Β ligand (RANKL) and increased the expression of osteoprotegerin (OPG) in AA-FLS via the regulation of IL-17/IL-17RA/STAT-3 signaling cascade. The therapeutic efficiency of FA on IL-17 signaling was further confirmed by knockdown of IL-17RA using small interfering RNA or blocking of STAT-3 activation with S3I-201. The molecular docking analysis revealed that FA manifests significant ligand efficiency toward IL-17RA, STAT-3, IL-23, and RANKL proteins. This study provides new evidence that FA can be used as a potential therapeutic agent for inhibiting IL-17-mediated disease severity and bone erosion in RA.
29761420 Long-Term Radiographic and Patient-Reported Outcomes in Patients with Rheumatoid Arthritis 2018 Dec INTRODUCTION: Here we examine the relationship between achieving different levels of disease activity with tofacitinib (an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis), long-term structural progression, and patient-reported physical function. METHODS: This was a post hoc analysis of two 24-month, phase III randomized controlled trials in methotrexate (MTX)-naïve (ORAL Start [NCT01039688]) or MTX-inadequate responder (IR) patients (ORAL Scan [NCT00847613]) receiving tofacitinib 5 or 10 mg twice daily as either monotherapy or with background MTX. The modified total Sharp score (mTSS) and Health Assessment Questionnaire-Disability Index (HAQ-DI) were analyzed at month 24 according to disease activity at month 6 defined by the Clinical Disease Activity Index (CDAI) or the Disease Activity Score in 28 joints, C-reactive protein (DAS28CRP). RESULTS: Mean changes from baseline in mTSS at month 24 were less in patients with CDAI remission at month 6 than in those with CDAI moderate/high disease activity (MDA/HDA) at month 6. A DAS28CRP of < 1.9 most closely approximated CDAI remission (≤ 2.8). Tofacitinib appeared to inhibit joint damage in the presence of persistent inflammation compared with MTX. More patients receiving tofacitinib or MTX with CDAI remission or low disease activity (LDA) at month 6 reported normative HAQ-DI scores (< 0.5) at month 24 than did those with CDAI MDA/HDA. CONCLUSION: Regardless of treatment, in both MTX-naïve and MTX-IR patients, remission or LDA at month 6 was associated with successful long-term outcomes: inhibition of structural progression and normative HAQ-DI scores. Long-term outcomes were similar when patients achieved CDAI remission or a DAS28CRP of < 1.9, confirming that this is an appropriate cut-off for remission with DAS28CRP. Tofacitinib potentially inhibits joint damage even with persistent inflammation. FUNDING: Pfizer Inc. TRIAL REGISTRATION: Clinicaltrials.gov identifiers: NCT01039688 and NCT00847613.
29574622 Similar Improvements in Patient-Reported Outcomes Among Rheumatoid Arthritis Patients Trea 2018 Jun INTRODUCTION: In patients with rheumatoid arthritis (RA), combination treatment with methotrexate (MTX) and adalimumab is more effective than MTX monotherapy. From the patients' perspective, the impact of reduced MTX doses upon initiating adalimumab is not known. The objective was to evaluate the effects of low and high MTX doses in combination with adalimumab initiation on patient-reported outcomes (PROs), in MTX-inadequate responders (MTX-IR) with moderate-to-severe RA. METHODS: MUSICA was a randomized, double-blind, controlled trial evaluating the efficacy of 7.5 or 20 mg/week MTX, in combination with adalimumab for 24 weeks in MTX-IR RA patients receiving prior MTX ≥ 15 mg/week for ≥ 12 weeks. PROs were recorded at each visit, including physical function, health-related quality-of-life, work productivity, quality-of-sleep, satisfaction with treatment medication, sexual impairment due to RA, patient global assessment of disease activity (PGA), and patient pain. Last observation carried forward was used to account for missing values. RESULTS: At baseline, patients in both MTX dosage groups had similar demographics, disease characteristics, and PRO scores. Overall, initiation of adalimumab led to significant improvements from baseline in the PROs assessed for both MTX dosage groups. Improvements in presenteeism from baseline were strongly correlated with corresponding improvements in SF-36 (vitality), pain, and physical function. Physical and mental well-being had a good correlation with improvement in sleep. Overall, improvements in disease activity from baseline were correlated with improvements in several PROs. CONCLUSIONS: The addition of adalimumab to MTX in MTX-IR patients with moderate-to-severe RA led to improvements in physical function, quality-of-life, work productivity, quality of sleep, satisfaction with treatment medication, and sexual impairment due to RA, regardless of the concomitant MTX dosage.

30034392 Attenuation of Rheumatoid Inflammation by Sodium Butyrate Through Reciprocal Targeting of 2018 Rheumatoid arthritis (RA) is a systemic autoimmune disease caused by both genetic and environmental factors. Recently, investigators have focused on the gut microbiota, which is thought to be an environmental factor that affects the development of RA. Metabolites secreted by the gut microbiota maintain homeostasis in the gut through various mechanisms [e.g., butyrate, which is one of the major metabolites of gut microbiota, exerts an anti-inflammatory effect by activating G-protein-coupled receptors and inhibiting histone deacetylases (HDACs)]. Here, we focused on the inhibition of the HDACs by butyrate in RA. To this end, we evaluated the therapeutic effects of butyrate in an animal model of autoimmune arthritis. The arthritis score and incidence were lower in the butyrate-treated group compared to the control group. Also, butyrate inhibited HDAC2 in osteoclasts and HDAC8 in T cells, leading to the acetylation of glucocorticoid receptors and estrogen-related receptors α, respectively. Additionally, control of the T(H)17/T(reg) cell balance and inhibition of osteoclastogenesis were confirmed by the changes in target gene expression. Interleukin-10 (IL-10) produced by butyrate-induced expanded T(reg) cells was critical, as treatment with butyrate did not affect inflammatory arthritis in IL-10-knockout mice. This immune-cell regulation of butyrate was also detected in humans. These findings suggest that butyrate is a candidate agent for the treatment of RA.
29911088 Rheumatic hand's clinical, functional and imagiological correlations following metacarpoph 2018 Mar OBJECTIVE: Evaluation of rheumatoid hand-associated metacarpophalangeal joint silicone arthroplasty most often relies on functional scores alone. This study aimed to understand the correlation between perceived and observed function, strength, and alignment. METHODS: Cross-sectional study including all 11 women (15 hands) submitted to second to fifth metacarpophalangeal joint arthroplasty due to rheumatoid arthritis involvement for a time period of seven years. Measurements relied on the Michigan Hand Outcomes Questionnaire, Lafayette Purdue Pegboard, pinch and grip strength, and analysis of a lateral "OK-sign" X-ray view. Correlation analysis used Spearman's coefficient, assuming statistical significance for p-values < 0.05. RESULTS: Objective function was strongly correlated with all other variables (p < 0.05), while perceived function failed to correlate with articular alignment in both measurements (p = 0.240 and p = 0.354). Strength and alignment were also strongly correlated (p < 0.05). CONCLUSIONS: Most measurements strongly correlate with each other, with emphasis on objective dexterity measurement.
30210691 LOX inhibitor HOEC interfered arachidonic acid metabolic flux in collagen-induced arthriti 2018 Arachidonic acid (AA) metabolic network generates a variety of products that mediate or modulate inflammatory reactions. (+)-2-(1-hydroxyl-4-oxocyclohexyl) ethyl caffeate (HOEC), isolated from Incarvillea mairei var. granditlora (Wehrhahn) Grierson, was found as an inhibitor of 5-LOX and 15-LOX in vitro. When evaluated in collagen-induced arthritis (CIA) rats, however, lowdose of HOEC (1 mg/kg) showed better efficacy than that of high dose (10 mg/kg). To study how HOEC interfered the AA metabolic pathway, in this study, we dynamically observed the changes of plasma AA metabolites (LTB4, LTC4, 15-HETE, PGE2, TXB2 and PGD2) in the CIA rats treated with different doses of HOEC by using enzyme-linked immunosorbent assay (ELISA). The results showed that eicosanoids were elevated synchronously at three time points in different treated rats. The incidence of arthritis had a higher correlation with LOX pathway while the COX pathway might be more important in the severity of arthritis. HOEC in all doses could inhibit LOX pathway in the beginning of arthritis while highdose of HOEC could induce the increase of COX metabolites in the later stage of disease. These dynamic changes of eicosanoids, depending on the regulation of metabolic flux, can be interfered by HOEC and thus affect the output of efficacy.
30938267 LRG is a novel inflammatory marker clinically useful for the evaluation of disease activit 2018 Jun By proteomic screening of sera obtained from patients with rheumatoid arthritis (RA), we previously identified leucine rich α2 glycoprotein (LRG) as a possible marker for inflammation. Unlike C-reactive protein (CRP), a biomarker widely used to evaluate inflammation, LRG is induced not only by IL-6 but also by other proinflammatory cytokines. In addition, LRG is upregulated not only in liver but also in local inflammatory sites. Therefore, serum LRG is a novel inflammatory marker applicable to evaluate inflammation in many diseases including ulcerative colitis in which serum CRP often fails to reflect disease activity and RA to which IL-6-blocking biologic agents such as tocilizumab are given as a first line therapy. Interestingly, evidence indicates that LRG is functionally involved in pathogenesis of inflammation, by promoting cellular proliferation, differentiation and angiogenesis via modulating TGF-β signaling.
30693040 The effects of conventional drugs in the treatment of rheumatoid arthritis on the serum li 2018 BACKGROUND: Rheumatoid arthritis (RA) is a common chronic autoimmune disorder that leads to damage of human joints. There are various treatment approaches in which different drugs are prescribed which have several alterations in serum lipids. This research aimed to study the effect of RA treatments on the serum lipids. MATERIALS AND METHODS: Two hundred randomly selected patients with RA were randomly assigned to three different groups. The first group of patients was treated with a combination of prednisolone (PRD) and hydroxychloroquine (HCQ). The second group was treated with three drugs including PRD, HCQ, and methotrexate (MTX). The third group was treated with four medications including PRD, HCQ, MTX, and sulfasalazine. Within each group, the lipid factors such as triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL), and high-density lipoprotein (HDL), erythrocyte sedimentation rate, and visual analog scale were measured at the beginning of the experiment and 6 months after exposing the treatments. For each group, we also calculated the Disease Activity Score-28 (DAS-28). The analysis of variance revealed that the overall DAS-28 was significantly different among the three groups. RESULTS: In the first group, the level of TG and TC significantly decreased (P = 0.015 and P ≤ 0.001, respectively). In the second group, the level of TG and LDL significantly decreased (P = 0.009). In the third group, the LDL level increased considerably (P < 0.001). The HDL level significantly increased in all three groups (P = 0.012, P = 0.014, and P = 0.028, respectively). CONCLUSION: The treatment PRD + HCQ + MTX was more effective in reducing the LDL level and increasing the HDL level. To reduce the risk of cardiovascular diseases in patients with RA, it is important to prescribe the combination of drugs which leads and normalizes the lipid profile levels.
29853721 Lack of significant association between selected STAT3 polymorphisms and rheumatoid arthri 2018 OBJECTIVES: Rheumatoid arthritis (RA) is the most common systemic inflammatory disease and is of unknown etiology. The altered balance between immunosuppressive and inflammatory T cell subpopulations exerts a huge impact on RA pathogenesis. The STAT3 protein regulates genes involved in the immune responses. It regulates maturation of T and B cells. Its abnormal activity is significantly associated with autoimmune diseases and cancer development. We aimed to evaluate the contribution of three potentially functional single nucleotide polymorphisms (SNPs) within the STAT3 gene to susceptibility and severity of RA in the Polish population. MATERIAL AND METHODS: A total of 595 patients with RA and 330 healthy individuals were included in the study. DNA from patients and healthy subjects was obtained from peripheral blood using standard DNA isolating methods. The STAT3 rs1053005, rs1026916 and rs2293152 polymorphisms were genotyped using the TaqMan SNP genotyping assay. The accuracy of SNP genotyping was confirmed using direct DNA sequence analysis. RESULTS: The distribution of STAT3 polymorphisms did not differ significantly between cases and controls. Our results revealed a tendency only, where rs1026916 AA genotype occurred more frequently in RA patients compared to healthy controls, in codominant (p = 0.09), dominant (p = 0.06) and recessive (p = 0.09) models. STAT3 rs2293152 polymorphism was associated with higher DAS28 (p = 0.014 codominant model; p = 0.003 dominant model), increased number of swollen joints (p = 0.02), higher VAS (p = 0.01) and higher HAQ score (p = 0.05). CONCLUSIONS: We did not observe a significant association between the three studied STAT3 genetic variants and increased susceptibility to or severity of RA. Only the STAT3 rs2293152 polymorphism was associated with parameters that indicate a more severe course of the disease. However, its distribution did not differ between RA and control groups. According to our observations these 3 studied STAT3 SNPs may not be used as risk factors for developing RA.
29401671 Understanding Chinese Medicine Patterns of Rheumatoid Arthritis and Related Biomarkers. 2018 Feb 3 Background: A considerable number of Rheumatoid Arthritis (RA) patients only experience side effects from treatment, with little to no actual pain relief. The combination of disease diagnosis in biomedicine and multi-disciplinary integrative approaches such as Chinese Medicine (CM), can help to identify different functional diagnosis of RA in the context of biomarker discovery. We aimed to analyse CM patterns in RA and their biomarker profiles. Methods: Four electronic databases (web of science, CINAHL, Scopus and PubMed) were searched. The reference list of all identified reports and articles were searched for additional studies. All study designs were included and no date limits were set. Studies were considered if they were published in English and explored the possible biomarkers profiles in RA patients, classified according to the American College of Rheumatology and categorized in CM as either cold, heat/hot or deficiency patterns. Methodological quality of included studies was assessed using checklists adapted from the ©Critical Appraisal Skills Programme by two independent reviewers. A narrative synthesis was conducted, using thematic analysis. Results: A total of 10 articles were included. The studies examined 77 healthy volunteers and 1150 RA patients categorized as cold, heat/hot or deficiency pattern and related biomarkers were identified individually or concomitantly. Conclusions: CM pattern differentiation based on clinical signs and symptoms showed a diverse range of biomolecules, proteins and genes from RA patients correlated well with cold, heat/hot or deficiency phenotype-based CM patterns and could be used as diagnostic biomarkers for early detection, disease monitoring and therapeutic targets.
29209946 Usability and Patient Preference Phase 3 Study of the Sarilumab Pen in Patients with Activ 2018 Jun INTRODUCTION: Sarilumab is a human monoclonal antibody that blocks the interleukin-6 receptor alpha (IL-6Rα). The phase 3 SARIL-RA-EASY study (EASY) assessed the robustness of an autoinjector (pen) for administering sarilumab when used by adults with active moderate-to-severe rheumatoid arthritis (RA) who are candidates for anti-IL-6R therapy in an unsupervised real-world setting. METHODS: EASY was a 12-week, multicenter, randomized, open-label, parallel-group usability study of the sarilumab pen and prefilled syringe. Patients were randomized 1:1:1:1 to sarilumab 150 or 200 mg every 2 weeks (q2w) administered via pen or syringe, plus background disease-modifying antirheumatic drugs. Patients reported their ability to remove the pen cap and initiate and complete injections; negative responses were defined as product technical complaints (PTCs). The primary endpoint was the number of validated product technical failures (PTFs; PTC with a validated technical cause). This study was not powered to demonstrate bioequivalence or differences in efficacy among groups. RESULTS: A total of 217 patients were randomized. There were 600 successful injections with the sarilumab pen in 108 patients and no pen-associated PTFs. One PTC was observed (the pen was mistakenly activated before injection). At week 12, 88% of patients indicated the pen was "easy" to use, and 98% reported they were "satisfied" with the pen. Proportions of patients achieving an American College of Rheumatology 20/50/70 response and a 28-joint disease activity score by C-reactive protein < 2.6 were similar at each dose between the pen and syringe groups, as were the pharmacokinetics. There were no clinically meaningful differences in adverse events (AEs), serious AEs, and AEs leading to discontinuation in the pen and syringe groups. The most common treatment-emergent AEs were infections and neutropenia. CONCLUSION: This study demonstrated the ease of use and robustness of the sarilumab pen when used by patients with RA in an unsupervised setting. Pharmacokinetics, safety, and efficacy were generally similar for the pen and syringe groups (NCT02057250). FUNDING: Sanofi Genzyme and Regeneron Pharmaceuticals, Inc.

30197505 A discrete choice experiment on preferences of patients with rheumatoid arthritis regardin 2018 OBJECTIVE: To comprehensively describe the identification, refinement, and selection of attributes and levels for a discrete choice experiment (DCE) on preferences of patients with rheumatoid arthritis (RA) regarding disease-modifying antirheumatic drugs (DMARDs). METHODS: A mixed-methods approach, consisting of three consecutive steps: a literature review, expert recommendations, and focus groups. Attributes and levels were identified by a scoping review and compiled into a list that was evaluated on its relevance by an expert panel. The list that resulted thereafter was used to inform three focus groups, including 23 patients with RA. New attributes and levels could be identified during the focus groups. Also, a ranking exercise was performed. The patients individually ranked the attributes (ie, the ones on the list and newly identified attributes) by relevance. The patients' individual rankings were summed to derive a ranking at group level and make an a priori selection of the most relevant attributes. The group discussions were transcribed for qualitative analysis. RESULTS: Nineteen attributes, each specified by two to seven levels, were identified by the scoping review. The expert recommendations resulted in the removal of one attribute. Furthermore, two new attributes and levels were identified and two attributes were split into two. One new attribute was identified during the focus groups. The results of the ranking exercise and qualitative analysis led to the refinement and selection of the following attributes: route of administration, frequency of administration, chance of efficacy, onset of action, risk of serious infections, risk of liver injury, and risk of cancer. Each attribute was specified by three levels. CONCLUSION: This study contributes to the limited literature on the development of attributes and levels. Future research should pay more attention to a comprehensive description of this process. It ensures transparency and thereby allows researchers to judge a DCE's quality and generalizability.
30174838 Clinicopathological features of lung cancer in patients with rheumatoid arthritis. 2018 Jul BACKGROUND: Rheumatoid arthritis (RA) is a connective tissue disorder (CTD) associated with an increased risk of malignancy including lung cancer (LC). METHODS: Clinicopathologic characteristics of LC patients with RA and without systemic CTD were compared to identify the potential differences. A further intra-group comparison was conducted in LC patients with RA according to smoking status to explore the effect of smoking on the clinicopathologic characteristics of LC patients with RA. RESULTS: A total of 44 LC patients with RA and 176 LC patients without systemic CTD were included in this study. There were no statistically significant differences in the distribution of age, gender, smoking status, histology type, and tumor location between the two groups. However, a significantly larger proportion of patients with stage IV LC was noted in LC with RA group (59.1% vs. 39.2%, P=0.017). Besides, more LC patients with RA had an Eastern Cooperative Oncology Group (ECOG) performance score (PS) ≥2 (8.0% vs. 20.5%, P=0.015). On multivariate analysis, tumor stage (OR: 1.41, 95% CI: 1.23-13.70, P=0.021) and presence of RA (OR: 1.35, 95% CI: 1.34-11.16, P=0.012) demonstrated independent associations with poorer ECOG PS. RA-interstitial lung disease (RA-ILD) was observed in 18 LC patients (40.9%) with RA. Among them, usual interstitial pneumonia (UIP) was observed only in past or current smokers, whereas non-specific interstitial pneumonia (NSIP) was observed only in non-smokers. CONCLUSIONS: There were no statistically significant differences in the distribution of age, gender, smoking status, histology type, and tumor location between LC patients with RA and those without systemic CTD. Compared with LC patients without CTD, LC patients with RA were more likely to be diagnosed at an advanced stage and have a poorer ECOG PS score, and were less likely to receive surgery, radiotherapy, chemotherapy and targeted therapy.
30123797 Chemerin and PEDF Are Metaflammation-Related Biomarkers of Disease Activity and Obesity in 2018 Objective: Obesity is a risk factor for Rheumatoid Arthritis (RA) being associated to low grade inflammation. This study aimed to determine whether PEDF and Chemerin are biomarkers of inflammation related to fat accumulation in RA and to investigate whether weight loss associates with clinical disease improvement through the modification of fat-related biomarkers in overweight/obese RA with low-moderate disease. Participants and Methods: Two-hundred and thirty RA patients were enrolled, of whom 176 at disease onset treated according to a treat-to-target strategy (T2T) and 54 overweight/obese RA in stable therapy and low-moderate disease activity. Gene expression of adipokines, interleukin-6 and their receptors were examined in adipose tissue from obese RA. Obese RA with low-moderate disease activity underwent low-calories diet aiming to Body Mass Index (BMI) reduction >5%, maintaining RA therapy unchanged. Chemerin, PEDF and Interleukin-6 plasma values were assessed by ELISA and disease activity was evaluated. Results: At RA onset, PEDF and Chemerin plasma values correlated with BMI (p < 0.001) but only Chemerin plasma values correlated with disease activity (p < 0.001). After adopting a T2T strategy, Chemerin arose as an independent factor associated with remission in early RA [OR(95%CIs):0.49(0.25-0.97)]. Moreover, after low-calories diet, RA with low-moderate disease activity reaching BMI reduction ≥5% (62.6%) at 6 months had significant decrease of PEDF (p < 0.05) and Chemerin (p < 0.05) plasma values, in parallel with the improvement in disease activity. Conclusions: PEDF and Chemerin arose as biomarkers of obesity and metaflammation respectively, providing a link between chronic inflammation and excess of body weight in RA. Therefore, BMI reduction of at least 5% in obese RA allowed better disease control without modifying RA treatment.
29915769 Rhupus syndrome and Chiari's network. 2018 Jan A 69-year-old female patient was admitted to our clinic with photosensitivity, symmetric erosive polyarthritis, and cutaneous vasculitis of lower extremities. Rhupus syndrome was diagnosed, and Chiari's network in the right atrium and interatrial septum patent foramen ovale was achieved on transthoracic and transesophageal echocardiography. If it is thought that increased prevalence of antiphospholipid antibodies in patients with rhupus, this congenital remnant is important for the thrombosis risk, cardiac event, and stroke. The association of both diseases may lead to more serious events and cause worse prognosis. Here, our aim is to present a 69-year-old female patient with rhupus syndrome presenting with cutaneous vasculitis and Chiari's network in the right atrium.

31435337 Clinical patterns of seronegative spondyloarthropathies in a tertiary centre in Pakistan. 2018 Jun OBJECTIVES: The patterns of spondyloarthropathies (SpA) differ across regions globally, and an understanding of these patterns is important for the correct diagnosis of this condition. The aim of this study was to evaluate the presenting symptoms and clinical patterns of SpA in a community of low socioeconomic status in Pakistan. METHODS: This clinical observational study was conducted in a tertiary care teaching hospital from July 2016 to June 2017. Five thousand patients were initially recruited in the rheumatology clinic. A total of 114 patients were finally selected and enrolled in this study, as defined by the inclusion criteria. All demographic variables were recorded and baseline clinical investigations were performed. The European Spondyloarthropathy Study Group (ESSG) diagnostic criteria were used to diagnose the condition and classify the study participants. RESULTS: Of the 114 patients, 64% (73 patients) were men and 36% (41 patients) were women. The mean age of the patients ranged 25-65 years. The men were affected twice as much as women with a ratio of 2:1.4. Men in the age group of 30-60 years constituted a large proportion of the study population. The most frequently diagnosed subtypes were ankylosing spondylitis, reactive arthritis, and psoriatic arthritis. The most common presenting symptoms were sacroiliitis, inflammatory spinal pain, and synovitis. CONCLUSION: Males had a higher prevalence of SpA. Ankylosing spondylitis, psoriatic arthritis, and reactive arthritis were the most commonly diagnosed subtypes.
29968102 [In-label treatment of inflammatory joint diseases]. 2018 Sep The correct use of therapeutic agents in accordance with their approved label is a requirement for a safe therapy and is often linked to the possibility of reimbursement; however, the use of drugs outside the label approval (off-label treatment) is a commonly used practice in rheumatology. This occurs because sufficient clinical trials are often lacking, particularly for rare diseases. This overview gives an insight into the correct use of disease-modifying antirheumatic drugs (DMARDs). It should be noted that there are divergent treatment guidelines that are based on guidelines or recommendations from public authorities, such as the Federal Joint Committee (GBA). A further example is that modifying the dose when the treatment goal is reached is only intended for some of the drugs in the course of the disease. Clinical trials which address such questions could help to modify or add to the label, as for example has now been successfully achieved for the treatment with certolizumab in pregnancy.
