28744511 | Sublaminar wire migration into the medulla oblongata: a case report. | 2017 Jun | Atlantoaxial procedures have been developed in an effort to ensure solid C1-C2 fusion. However, techniques that involve sublaminar wiring have the potential for neural structure injury. We present the management of a patient who previously underwent Gallie fusion 10 years ago and is presenting with a dislodged titanium wire that has migrated into the medulla oblongata. A 52-year-old female patient known with rheumatoid arthritis presented with truncal ataxia and food regurgitation 10 years after undergoing a C1-C2 Gallie fusion. A computerized tomography (CT) scan revealed that a wire from her Gallie fusion procedure migrated into the medulla oblongata. The patient underwent foramen magnum decompression with C1 bilateral laminectomy, instrumentation, and removal of a migrated wire. Six months later, a CT scan showed that all occipital screws were pulled out. In the revision surgery, new occipital screws were placed with a resultant significant improvement in patient's gait postoperatively. Wire migration as a differential diagnosis should be considered in patients presenting with neurological dysfunction who underwent surgical treatment with sublaminar wire fusion techniques. | |
28209465 | Identification of highly potent and selective PI3Kδ inhibitors. | 2017 Jul 1 | Selective PI3Kδ inhibitors have recently been hypothesized to be appropriate immunosuppressive agents for the treatment of immunological disorders such as rheumatoid arthritis. However, few reports have highlighted molecules that are highly selective for PI3Kδ over the other PI3K isoforms. In this letter, isoform and kinome selective PI3Kδ inhibitors are presented. The Structural Activity Relationship leading to such molecules is outlined. | |
28286042 | The therapeutic effects of Periploca forrestii Schltr. Stem extracts on collagen-induced a | 2017 Apr 18 | ETHNOPHARMACOLOGICAL RELEVANCE: Periploca forrestii Schltr. is a classical traditional Chinese medicine (TCM) called Heilonggu (HLG) in China. According to the theory of TCM, it possesses the efficacy of eliminating wind and removing dampness. In clinical practice, it is commonly used for the treatment of rheumatoid arthritis. The present work aimed to evaluate the anti-rheumatism activity of HLG ethanol extract and reveal the underlying molecular mechanism by employing an animal model of collagen-induced rheumatoid arthritis (CIA) in rats. MATERIALS AND METHODS: The CIA was induced in male Sprague-Dawley rats by intradermal injection of bovine collagen-II in complete Freund's adjuvant (CFA) at the base of tail. The rats received oral administration of HLG (200 and 400mg/kg) from day 1, with the treatment lasting for 28 days. A variety of indicators were measured for evaluation of anti-rheumatism effect, including paw swelling, arthritis scores, and histopathological changes. Furthermore, the serum levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and prostaglandin E2 (PGE2), as well as cyclooxygenase-2 (COX-2), nuclear factor NF-κB p65 and Src kinase in joint synovial tissues were detected to explore the possible mechanisms. RESULTS: The administration of HLG significantly restored type II collagen-induced arthritis in rats as evidenced by decrease in paw swelling and inflammatory factors in serum. Meanwhile, this treatment also notably reduced NF-κB p65 and COX-2 expression. Surprisingly, the activity of Src kinase was also inhibited demonstrated by downregulation of phosphorylated Src. CONCLUSION: Our results revealed that HLG possessed observable therapeutic action on collagen-induced arthritis by inhibiting the activation of Src and nuclear translocation of NF-κB in rats. HLG may serve as a potential candidate for the management of patients with RA. | |
29276516 | Myostatin Promotes Interleukin-1β Expression in Rheumatoid Arthritis Synovial Fibroblasts | 2017 | Rheumatoid arthritis (RA) is characterized by the infiltration of a number of pro-inflammatory cytokines into synovial fluid and patients with RA often develop joint destruction and deficits in muscle mass. The growth factor myostatin is a key regulator linking muscle mass and bone structure. We sought to determine whether myostatin regulates rheumatoid synovial fibroblast activity and inflammation in RA. We found that levels of myostatin and interleukin (IL)-1β (a key pro-inflammatory cytokine in RA) in synovial fluid from RA patients were overexpressed and positively correlated. In in vitro investigations, we found that myostatin dose-dependently regulated IL-1β expression through the ERK, JNK, and AP-1 signal-transduction pathways. Computational analysis confirmed that miR-21-5p directly targets the expression of the 3' untranslated region (3' UTR) of IL-1β. Treatment of cells with myostatin inhibited miR-21-5p expression and miR-21-5p mimic prevented myostatin-induced enhancement of IL-1β expression, showing an inverse correlation between miR-21-5p and IL-1β expression during myostatin treatment. We also found significantly increased paw swelling in an animal model of collagen-induced arthritis (CIA), compared with controls; immunohistochemistry staining revealed substantially higher levels of myostatin and IL-1β expression in CIA tissue. Our evidence indicates that myostatin regulates IL-1β production. Thus, targeting myostatin may represent a potential therapeutic target for RA. | |
30210560 | DEC2 Blocks the Effect of the ARNTL2/NPAS2 Dimer on the Expression of PER3 and DBP. | 2017 Aug 11 | The expression of clock genes ARNTL2, NPAS2 and DEC2 are disturbed in rheumatoid arthritis, an autoimmune disease with circadian variation of symptoms. We have shown that TNF is a potent inducer of these genes. We investigated the regulation of ARNTL2 and NPAS2 by TNF and elucidated their effect on other clock gene expressions. Additionally, we studied the effect of DEC1 and DEC2 on ARNTL, ARNTL2 and NPAS2. Cultured primary human fibroblasts were stimulated with TNF and the effects on ARNTL2 and NPAS2 were studied with RT-qPCR and immunofluorescence staining. The role of NF-κB was analyzed using IKK-2 inhibitor IMD-0354. TNF promoted ARNTL2 localization into the nuclei. Similar to DEC2, the effects of TNF on ARNTL2 and NPAS2 expressions were mediated via NF-κB. Cloned ARNTL, ARNTL2, NPAS2, DEC1 and DEC2 were transfected into HEK293. The ARNTL2/NPAS2 dimer was a weaker inducer of PER3 and DBP than ARNTL/NPAS2. ARNTL2 and NPAS2 are regulated by TNF via the same mechanism as DEC2. Compared to their paralogs they have unique effects on other circadian components. Our data suggest that these genes are responsible, at least in fibroblasts, for the accurate adaptation of circadian timekeeping in individual cells during inflammation. | |
28326189 | Sarilumab improves patient-reported outcomes in rheumatoid arthritis patients with inadequ | 2017 | OBJECTIVE: To evaluate effects of the anti-interleukin-6 receptor monoclonal antibody sarilumab administered with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) on patient-reported outcomes (PROs) in the TARGET trial in patients with rheumatoid arthritis (RA) with inadequate response or intolerance to tumour necrosis factor inhibitors (TNF-IR). METHODS: 546 patients (81.9% female, mean age 52.9 years) were randomised to placebo, sarilumab 150 or 200 mg subcutaneously every 2 weeks + csDMARDs. PROs included patient global assessment (PtGA); pain and morning stiffness visual analogue scales; Health Assessment Questionnaire Disability Index (HAQ-DI); Short Form-36 Health Survey (SF-36); FACIT-Fatigue (FACIT-F); Work Productivity Survey-Rheumatoid Arthritis (WPS-RA) and Rheumatoid Arthritis Impact of Disease (RAID). Changes from baseline at weeks 12 and 24 were analysed using a mixed model for repeated measures; post hoc analyses included percentages of patients reporting improvements ≥ minimum clinically important differences (MCID) and scores ≥ normative values. RESULTS: Sarilumab + csDMARDs doses resulted in improvements from baseline at week 12 vs placebo + csDMARDs in PtGA, pain, HAQ-DI, SF-36 and FACIT-F that were maintained at week 24. Sarilumab improved morning stiffness and reduced the impact of RA on work, family, social/leisure activities participation (WPS-RA) and on patients' lives (RAID). Percentages of patients reporting improvements ≥MCID and ≥ normative scores were greater with sarilumab than placebo. CONCLUSIONS: In patients with TNF-IR RA, 150 and 200 mg sarilumab + csDMARDs resulted in clinically meaningful patient-reported benefits on pain, fatigue, function, participation and health status at 12 and 24 weeks that exceeded placebo + csDMARDs, and were consistent with the clinical profile previously reported. TRIAL REGISTRATION NUMBER: NCT01709578; Results. | |
28955495 | Sustainability of TNF-blocker tapering in rheumatoid arthritis over 3 years: long-term fol | 2017 | INTRODUCTION: We have limited data on the sustainability of tumour necrosis factor (TNF)-blocker tapering in rheumatoid arthritis (RA) in remission over the long term in real-life settings. This study aimed to assess the probability of sustained dose reduction of TNF-blockers in an observational 3-year extended follow-up of the Spacing of TNF-blocker injections in Rheumatoid ArthritiS Study (STRASS), a randomised controlled trial comparing progressive TNF-blocker injections (spacing arm (S-arm) to maintenance arm (M-arm)) in patients with RA in stable remission. METHODS: In 2015, clinical data for the completer population were retrospectively collected at 1, 2 and 3 years after the end of the trial. The endpoints were the proportion of patients free of a biological disease-modifying antirheumatic drug (bDMARD) treatment, a sustainably spaced injection of TNF-blockers and a full-dose regimen as well as the mean dose of bDMARD intake and treatment switch rate. RESULTS: Overall, 96 patients (76.8% of the completers) had data available up to 3 years; 11.5% discontinued TNF-blockers (5.8% vs 18.2% in the M-arm and S-arm, p=0.06), 30.2% had a tapered regimen (28.8% vs 31.8%, p=0.76) and 37.5% retained a full dose (44.2% vs 29.5%, p=0.14). The mean TNF-blocker dose quotient was 66% of the full dose (74% vs 58% in the M-arm and S-arm, p=0.06); 20.8% switched to another bDMARD (21.2% vs 20.5%, p=0.94). CONCLUSION: Sustained TNF-blocker de-escalation or withdrawal is achievable in 41% of patients over 3 years with limited dose reduction. Optimal strategies remain to be determined to maintain remission after TNF-blocker tapering or discontinuation. | |
27846750 | Survey on attitudes regarding EULAR recommendations for the role of nurses involved in med | 2017 Sep | OBJECTIVE: We seek to evaluate the opinions of nurses and doctors in Japan regarding EULAR recommendations for nurses' roles in the management of chronic inflammatory arthritis. METHODS: This is a cross-sectional survey within Japan. We randomly selected nurses and doctors engaged in consultation of patients with rheumatoid arthritis (RA) and assessed their agreement and opinions on the feasibility of implementing EULAR recommendations, including potential barriers. RESULTS: 431 nurses and 128 doctors completed the questionnaire. For both nurses and doctors, levels of feasibility showed statistically significant lower results compared with those of agreement for all items. When compared between nurses and doctors, agreement showed no statistically significant differences, while nurses' answers were statistically significant lower for feasibility. Insufficient time, staff and knowledge, lack of established procedures and facilities, and lack of an education system for nurses were cited as barriers to the feasibility of implementing EULAR recommendations. CONCLUSIONS: This is the first survey within Japan evaluating opinions regarding EULAR recommendations for nurses' roles. We found that while agreement was high, feasibility was generally believed to be low. We recommend further research and collaboration between medical professionals in order to implement these recommendations in Japan. | |
28562338 | An herbal formula attenuates collagen-induced arthritis via inhibition of JAK2-STAT3 signa | 2017 Jul 4 | Wenjinghuoluo prescription, a traditional Chinese medicine compound treatment of rheumatoid arthritis characterized by wind-cold-dampness arthralgia, contains five herbs, namely, C. cassia Presl., Cinnamomum cassia Presl., Paeonia lactiflora Pall., Saposhnikovia divaricate (Turcz.) Schischk., and Clematis chinensis Osbeck. We have reported that WJHL could inhibit the production of inflammatory mediators in immune cells. This study explored the effect and mechanism of WJHL on collagen-induced arthritis mice. WJHL could significantly improve clinical arthritic conditions; inhibit bone erosion and osteophyte formation in joints; decrease expression of proinflammatory cytokines (TNF-α, IL-1β, IL-6, and IL-17); reduce protein expression levels of JAK2, p-JAK2, STAT3, p-STAT3 and gene expression levels of JAK2, STAT3, IL-17A, RORγt mRNA; elevate osteoprotegerin and Foxp3 mRNA levels and lower Th17 cell proportions in splenocytes. Results suggest that WJHL, specifically regulating the JAK2/STAT3 pathway and Th17 cells, may be a promising herbal medicine candidate for the treatment of RA. | |
29201995 | Protective effect of antirheumatic drugs on dementia in rheumatoid arthritis patients. | 2017 Nov | INTRODUCTION: Rheumatoid arthritis is a systemic inflammatory disease, and classical disease-modifying antirheumatic drugs (cDMARDs) have proven efficacy. It is unknown what impact cDMARDs might have on dementia as an outcome. METHODS: Incident diagnoses of rheumatoid arthritis in persons over 18Â years from 1995 to 2011 were identified from the UK Clinical Practice Research Datalink. There were 3876 cDMARD users and were propensity score matched to 1938 nonusers, on a wide range of confounders. Impact on dementia was assessed using survival models. RESULTS: cDMARD users were at reduced risk of dementia (hazard ratio: 0.60; 95% confidence interval: 0.42-0.85). The effect was strongest in methotrexate users (hazard ratio: 0.52; 95% confidence interval; 0.34-0.82). DISCUSSION: The strong effect of cDMARD use on halving of dementia risk requires replication in a trial and may provide an important therapeutic pharmacological treatment. | |
28725502 | Universal 2 Wrist Arthroplasty in Rheumatoid Arthritis. | 2017 Aug | Purpose  The aim of this study was to evaluate the mid- to long-term outcomes and complications in patients affected by rheumatic diseases treated with the Universal 2 (U2) total wrist arthroplasty (TWA). Methods  We reviewed, in a retrospective, noncontrolled cohort study, 22 patients affected by rheumatoid arthritis (RA), who underwent U2 total wrist replacement between March 2003 and January 2014 for the treatment of 23 rheumatoid wrists with the aim of obtaining the remission of pain and a range of motion (ROM) useful for daily activities, according to the patients' demands, as an alternative to total wrist arthrodesis. The cohort of patients included 20 females and 2 males, with a mean age of 54.9 years. Residual pain, preoperative ROM, postoperative ROM increases, grip strength, radiographic changes, long-term complications, and reasons for revision or failures were evaluated. Results  In this study, 22 patients were evaluated at a mean follow-up of 82.3 months (range: 2-12 years). All patients had good or complete pain relief, the mean visual analogue scale pain score was 0.82. The mean grip strength improved and postoperatively was 11 kg (Jamar). The mean total ROM of flexion-extension was 72.3 degrees; radial-ulnar deviation 24.9 degrees. The mean QuickDASH score of 49 and patient rate wrist/hand evaluation of 41.7 a revision surgical procedure in six cases (26%): in two cases, a carpal component revision procedure and in four cases, total implant failures requiring either conversion to a Swanson spacer or wrist joint fusion. Conclusion  TWA provides pain relief, preserves motion, and improves function in severe degenerative RA. Our results at a mid- to long-term follow-up with the U2 prosthesis were encouraging and represent, when indicated, a valid alternative to fusion which is less appealing for RA patients. Level of Evidence  Level of evidence is therapeutic IV. | |
28690235 | [Diagnosis and treatment for one case of elderly diabetes complicated with Still's disease | 2017 Jun 28 | Adult onset Still's disease (AOSD) is a clinical syndrome with multiple organ failure. The patients normally show intermittent high fever for a long time, a transient rash, arthritis or joint pain as the main performance, accompanied by an increase in granulocytes and enlargement in liver, spleen and lymph node. A 71-years-old female patient with type 2 diabetes admitted hospital because of high fever, skin rash, joint pain and increased granulocyte. After review of the iron protein, she was diagnosed as AOSD. We found that clinicians need to improve the understanding for this disease in order to make the early diagnosis, especially in elderly patients with diabetes mellitus. In such patients, ferritin may not be high at early time. However, when the symptoms and signs are consistent with clinical manifestations, and anti-infection treatment effect is poor, we should pay attention to the disease, and repeated review of ferritin is necessary to assist the early diagnosis. | |
28296747 | Adult-onset Still's disease with atypical cutaneous manifestations. | 2017 Mar | The diagnosis of adult-onset Still's disease (AOSD) can be very difficult. There are no specific tests available, and diagnosis is usually based on a symptom complex and the well-described typical evanescent rash seen in the majority of patients. However, in recent years, other atypical cutaneous manifestations of AOSD have been reported. These atypical skin eruptions often present in addition to the typical evanescent rash but may also be the only skin manifestation, resulting in delayed diagnosis because of under-recognition.In this study, we present 3 new cases of AOSD with atypical cutaneous manifestations diagnosed during a 30-year period in our department and review 78 additional cases previously reported (PubMed 1990-2016). These 81 patients form the basis of the present analysis.The overall prevalence of atypical cutaneous manifestations in our AOSD population was 14%. These manifestations may appear at any time over the course of the disease, and usually occur in patients who have persistent and severe disease, with a considerable frequency of clinical complications (23%), including serositis, myopericarditis, lung involvement, abdominal pain, neurologic involvement, and reactive hemophagocytic syndrome.The most representative and frequent lesion among the nonclassical skin rashes is the development of persistent pruritic papules and/or plaques. Interestingly, these lesions show a distinctive histological pattern. Other, less frequently observed lesions include urticaria and urticaria-like eruptions, generalized or widespread non-pruritic persistent erythema, vesiculopustular eruptions, a widespread peau d'orange appearance of the skin, and edema of the eyelids mimicking dermatomyositis without any accompanying skin lesion.The great majority of these patients required medium or high doses of glucocorticoids (including intravenous methylprednisolone pulse therapy in some cases) and, in nearly 40%, a more potent or maintenance immunotherapy with immunosuppressant drugs and/or biologic agents (mainly anakinra or tocilizumab) to control or manage symptoms because of a polycyclic or chronic course. The development of atypical cutaneous manifestations seems to be associated with a potentially worse prognosis, with a mortality rate reaching 8% primarily because of infectious complications related to immunosuppressive therapy.In conclusion, the appearance of atypical cutaneous manifestations is not uncommon in AOSD. Recognition of this clinical variant is crucial for the early diagnosis of AOSD, as it might imply persistent disease activity and the need for more aggressive treatment. | |
28042319 | Scavenger Receptor-Mediated Targeted Treatment of Collagen-Induced Arthritis by Dextran Su | 2017 | Rheumatoid arthritis (RA) is a chronic autoimmune disorder implicated in multiple joint affection and even disability. The activated macrophages perform a predominant role in onset and persistence of RA. Scavenger receptor (SR), one of several receptors overexpressed on the activated macrophages, is a specific biomarker for targeted therapy of numerous chronic inflammation diseases like RA. In this work, dextran sulfate-graft-methotrexate conjugate (DS-g-MTX) is synthesized and characterized, which exhibits excellent targetability to SR on the activated RAW 264.7 cells. Additionally, the enhanced accumulation and potent inflammatory inhibition are observed in the affected joint after intravenous injection of DS-g-MTX, compared to the treatment with dextran-graft-methotrexate (Dex-g-MTX), as is confirmed by the detection of histopathology and pro-inflammatory cytokines. Our work highlights DS-g-MTX as a potential therapeutic option for RA aiming the SR-expressed activated macrophages. | |
29951575 | Computational Systems Biology Approach for the Study of Rheumatoid Arthritis: From a Molec | 2018 | In this work we present a systematic effort to summarize current biological pathway knowledge concerning Rheumatoid Arthritis (RA). We are constructing a detailed molecular map based on exhaustive literature scanning, strict curation criteria, re-evaluation of previously published attempts and most importantly experts' advice. The RA map will be web-published in the coming months in the form of an interactive map, using the MINERVA platform, allowing for easy access, navigation and search of all molecular pathways implicated in RA, serving thus, as an on line knowledgebase for the disease. Moreover the map could be used as a template for Omics data visualization offering a first insight about the pathways affected in different experimental datasets. The second goal of the project is a dynamical study focused on synovial fibroblasts' behavior under different initial conditions specific to RA, as recent studies have shown that synovial fibroblasts play a crucial role in driving the persistent, destructive characteristics of the disease. Leaning on the RA knowledgebase and using the web platform Cell Collective, we are currently building a Boolean large scale dynamical model for the study of RA fibroblasts' activation. | |
29152095 | TIPE2 expression is increased in peripheral blood mononuclear cells from patients with rhe | 2017 Oct 20 | We investigated the changes in mRNA and protein expression of tumor necrosis factor-α-induced protein 8-like 2 (TIPE2) and PEST-containing nuclear protein (PCNP) in peripheral blood lymphocytes from 54 patients with rheumatoid arthritis (RA) and the spleens of model mice with collagen-induced arthritis (CIA) to generate new ideas for clinical diagnosis and treatment. Expression levels of both TIPE2 and PCNP were higher in RA patients and CIA mice than in their respective controls. They were also higher in the 32 patients with active RA than in the 22 with inactive RA (P < 0.001 for both). After comprehensively treating patients with active RA with anti-inflammatory and antirheumatic drugs for 6 months, they were stable, and there was no difference in TIPE2 levels between the treated patients and those with inactive RA (P = 0.85). In addition, TIPE2 mRNA levels in peripheral blood correlated positively with PCNP (R(2) = 0.744, P = 0.001). The DAS28 score correlated positively with peripheral blood TIPE2 levels in the RA patients (R(2) = 0.945, P = 0.001). These findings suggest TIPE2 expression increases with the severity of RA. | |
28955492 | ProNGF-p75NTR axis plays a proinflammatory role in inflamed joints: a novel pathogenic mec | 2017 | OBJECTIVE: To identify the role of mature nerve growth factor (mNGF), its immature form proNGF and their receptors in arthritis inflammation. METHODS: Real-time PCR, western blot and ELISA were performed to evaluate NGF, proNGF, their receptor and cytokine expression in synovial tissue and cells of patients with juvenile idiopathic arthritis (JIA) and rheumatoid arthritis (RA), and controls. RESULTS: proNGF and not mNGF is the prevalent form measured in synovial fluids of patients with JIA and RA with synovial fibroblasts as a major source of proNGF in the inflamed synoviae. p75NTR, the specific receptor for proNGF, is the NGF receptor most expressed in mononuclear cells of patients with JIA, while TrkA is the prevalent receptor in healthy donors. In ex vivo experiments the effects of proNGF differ from those of mNGF, suggesting that the balance of p75NTR and TrkA expression represents a critical factor in regulating mNGF/proNGF functions, determining which intracellular pathways and biological activities are triggered. Contrary to NGF, proNGF administration increased inflammatory cytokines but not interleukin (IL)-10 expression, inducing a stronger activation of p38 and JNK pathways. proNGF effects depend on its binding to p75NTR, as inhibition of p75NTR with neutralising antibodies or LM11A-31 abolished proNGF-induced production of IL-6 in patients' mononuclear cells, while inhibition of TrkA did not. There is a correlation in patients with arthritis between high p75NTR levels and severity of clinical symptoms. CONCLUSIONS: Our data suggest that an active proNGF-p75NTR axis promotes proinflammatory mechanisms contributing to chronic tissue inflammation, and that the use of p75NTR inhibitors may represent a new therapeutic approach in chronic arthritis. | |
28155923 | Diagnosis, prognosis and classification of early arthritis: results of a systematic review | 2017 | OBJECTIVE: To update the evidence pertaining to the diagnosis, prognosis and classification of patients with early arthritis (EA), and to inform the 2016 European League Against Rheumatism (EULAR) recommendations for the management of patients with EA. METHODS: MEDLINE, EMBASE and Cochrane databases were searched up to October 2015. The first part of the systematic literature review (SLR) involved a search for studies investigating the recognition and referral of EA. The second part involved a search for studies to identify the place of laboratory and imaging tests in establishing a diagnosis and a prognosis in patients with EA. RESULTS: Regarding the issue of referral of patients with EA (1643 hits), 4 studies were included. These studies were in support of early referral for patients with EA. Regarding the issue of diagnosis and prognosis of patients with EA (11 435 hits), 88 studies were included, evaluating mainly the value of rheumatoid factor (RF) and anticitrullinated-peptide antibodies (ACPAs). Sensitivity of these antibodies for a RA diagnosis in patients with EA was moderate (40-80%). Specificity was higher, notably for ACPAs (frequently >80%). ACPAs also showed better prognostic performance than RF (negative predictive values around 80%). We confirmed that structural damage on baseline X-rays is predictive of further radiographic progression in patients with EA. Regarding other imaging modalities, data are sparse. CONCLUSIONS: This SLR highlights the importance of early referral for patients with EA and confirms that RF and mainly ACPAs as well as a search for structural X-rays changes may help in the diagnosis and prognosis of patients with EA. | |
29551934 | Correlation of nuclear factor-κB, regulatory T cell and transforming growth factor β wit | 2017 Dec | Objective: Investigated the correlation of nuclear factor-κB, regulatory cells and transforming growth factor-β with rheumatoid arthritis. Methods: Included 65 cases of RA patients admitted in our hospital from June 2015 to December 2016 into case group, and included 50 healthy people into control group during the same period. Collected the peripheral detection of nuclear factor-κB, regulatory cells and transforming growth factor beta levels, and compared them between two groups. Results: The percentage of CD4(+), CD25(+) T cells in the case group was significantly lower than that in the control group (P < .05); There was no significant difference in the percentage of CD4(+), CD25(+) CD127(low/-), T cells between groups (P > .05); The levels of TGF - beta and NF - kappa B in the case group were higher than those in the control group, and the difference between the two groups was statistically significant (P < .05); The levels of ESR, CRP and RF in the case group were higher than those in the control group (P < .05). There was a negative correlation between the expression of nuclear factor-κB, transforming growth factor-β and RF level in RA patients by pearson correlation analysis, r = -0.652, P < .05. Conclusion: The expression levels of CD4(+), CD25(+) T cells in patients with RA are significantly decrease, which has a negative correlation with RA activity index RF, and showed that the pathogenesis of RA is related to the regulation of immune system. | |
29081616 | Biological Response Modifiers in Rheumatoid Arthritis: Systematic Review and Meta-analysis | 2017 Jul | OBJECTIVE: To analyze available evidence on the safety of different biological response modifiers which are used for a treatment of rheumatoid arthritis (RA). MATERIALS AND METHODS: We searched systematically for randomized controlled clinical trials on treatment of RA with different biological response modifiers, followed by a systematic review with meta-analysis. Trials were searched from MEDLINE and Cochrane Library databases. The following safety parameters reported in the selected trials were analyzed: number of patients suffering any adverse event (AE), withdrawal due to AEs, serious AE (SAEs), infections, serious infections, infusion reactions, injection site reactions, malignancies, and overall mortality. Undesired effects were estimated using combined relative risks (RR) and number needed to harm (NNH). Heterogeneity was evaluated by Cochrane's Q and I(2) statistics. RESULTS: According to inclusion criteria, a total of 43 trials (20,504 patients) were included in this study. A total number of AEs were found more with abatacept (RR: 1.05, NNH: 21.93). Withdrawal due to AEs was found with all biologicals, highest with anakinra (RR: 3.48, NNH: 15.70). Patients receiving newer tumor necrosis factor-alpha inhibitors, golimumab, were more likely to develop SAEs (RR: 2.44, NNH: 12.72) and infection (RR: 1.25, NNH: 10.09), and in certolizumab, serious infections (RR: 2.95, NNH: 37.31) were found more. Infusion reaction develops more with rituximab (RR: 1.52, NNH: 8.47). Etanercept showed the highest risk to develop infusion site reaction (RR: 5.33, NNH: 4.65). Biologicals showed no difference to their control counterparts in malignancy and mortality risk. CONCLUSION: This meta-analysis helps to clarify some frequently encountered and unanswered safety questions of different biological response modifiers, a new class of drugs, in the clinical care of RA patients. |
