29680881 | Baricitinib in Patients with Rheumatoid Arthritis and an Inadequate Response to Convention | 2018 Jun | INTRODUCTION: This article evaluates the efficacy and safety of baricitinib 4 mg versus placebo in United States including Puerto Rico (US) and rest of the world (ROW) subpopulations using data pooled from RA-BEAM and RA-BUILD, which enrolled patients with moderate-to-severe adult-onset rheumatoid arthritis (RA). METHODS: In RA-BEAM, patients with an inadequate response (IR) to methotrexate, at least one X-ray erosion, and high sensitivity C-reactive protein (hsCRP) ≥ 6 mg/L were randomized to placebo or orally administered baricitinib 4 mg daily or subcutaneously administered adalimumab 40 mg every other week. In RA-BUILD, patients with an IR to at least one conventional synthetic disease-modifying antirheumatic drug (csDMARD) and with hsCRP ≥ 3.6 mg/L were randomized to placebo or baricitinib 2 or 4 mg daily. Patients in both trials were biologic naive. In this post hoc analysis, data from both studies were pooled (714 baricitinib 4 mg-treated, 716 placebo-treated patients). RESULTS: Overall, 188 US and 1242 ROW patients were included. Subgroups differed in baseline characteristics including race, weight, age, time since RA diagnosis, current corticosteroid use, and previous csDMARD use. At weeks 12 and 24, baricitinib-treated patients had larger responses compared to placebo-treated patients for multiple efficacy outcomes: American College of Rheumatology 20/50/70 response, low disease activity, remission, Disease Activity Score 28-C-reactive protein, and Health Assessment Questionnaire-Disability Index. Overall, similar efficacy was observed in US and ROW subgroups with no notable safety differences between subgroups at weeks 12 or 24. CONCLUSION: Baricitinib 4 mg was efficacious compared to placebo in US and ROW subpopulations. Safety was similar between subgroups. FUNDING: Eli Lilly & Company and Incyte Corporation.

29657870 | Is the serum oxytocin level altered by treatment in rheumatoid arthritis patients complica | 2018 Mar | OBJECTIVE: The objective of this study was to investigate the factors associated with depression, including serum oxytocin (OXT) levels, disease activity, activities of daily living (ADL), and quality of life (QOL), and their effects on rheumatoid arthritis (RA). METHODS: This study included 42 RA patients who received treatment with a biological agent. We measured the following variables before and after 6 months of treatment: baseline characteristics, including age, sex, disease duration, smoking, and body mass index (BMI); prednisolone and methotrexate dose; serum level of matrix metalloproteinase-3 (MMP-3); erythrocyte sedimentation rate (ESR); and C-reactive protein (CRP) level. The disease activity of RA was assessed using the Simplified Disease Activity Index (SDAI); depression was assessed using the Hamilton Depression Rating Scale (HAM-D); ADL was assessed using the Health Assessment Questionnaire; and QOL was assessed using the Short Form (SF)-36. Serum OXT levels were determined using enzyme-linked immunosorbent assay. RESULTS: The HAM-D score significantly correlated with the SDAI, and the mental component summary (MCS) score of SF-36. However, the serum OXT levels did not correlate with the HAM-D score. Regression analysis using the HAM-D score as the objective variable identified female sex, smoking, BMI, and all the three component scores of SF-36, but not serum OXT levels, as significant factors. Comparisons between before and after treatment showed that the HAM-D score improved from 5 to 1.5; however, the serum OXT levels did not change. CONCLUSION: The variables of female sex, smoking, BMI, and QOL correlated with depression complicated with RA. However, serum OXT levels did not correlate directly. | |
29618976 | The Efficacy and Safety of Mainstream Medications for Patients With cDMARD-Naïve Rheumato | 2018 | Background: The mainstream medications for rheumatoid arthritis (RA) include conventional disease-modifying antirheumatic drugs (cDMARDs), which mostly are methotrexate (MTX), and biologic agents such as adalimumab (ADA), certolizumab (CZP), etanercept (ETN), golimumab (GOL), infliximab (IFX), and tocilizumab (TCZ). This network meta-analysis was aimed at evaluating the efficacy and safety of the medications above and interventions combining cDMARDs and biologic agents for patients with RA. Methods: PubMed, EMBASE, Cochrane Library, and ClinicalTrials.gov were searched systematically for eligible randomized controlled trials (RCTs). Outcomes concerning efficacy and safety were evaluated utilizing odds ratios (ORs) and 95% credible intervals (CrI). The outcomes of efficacy would be evaluated through remission and American College of Rheumatology (ACR) scores. The surface under the cumulative ranking curve (SUCRA) was calculated to rank each treatment on each index. Results: A total of 20 RCTs with 9,047 patients were included, and the efficacy and safety of the concerning interventions for RA were evaluated. Compared with cDMARDs alone, TCZ+MTX, ETN+MTX, IFX+MTX, TCZ, and ADA+MTX showed significant statistical advantage on ACR20, ACR50, and ACR70. Apart from that, as for remission, TCZ+MTX, IFX+MTX, TCZ, and CZP+MTX performed better compared to cDMARDs alone. The SUCRA ranking also indicated that TCZ+MTX was the intervention with best ranking in the entire four efficacy indexes followed by ETX+MTX and IFX+MTX. However, there was no obvious difference among these medications compared with cDMARDs when it comes to safety, which need more specific studies on that. Conclusion: TCZ+MTX was potentially the most recommended combination of medications for RA due to its good performance in all outcomes of efficacy. ETX+MTX and IFX+MTX, which also performed well, could be introduced as alternative treatments. However, considering the adverse events, the treatments concerning should be introduced with caution. | |
29417430 | Effect of Discontinuation or Initiation of Methotrexate or Glucocorticoids on Tofacitinib | 2018 Jun | INTRODUCTION: Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). We evaluated the effect of concomitant methotrexate (MTX) or glucocorticoid (GC) use on tofacitinib clinical efficacy. METHODS: Data were pooled from two open-label, long-term extension studies of tofacitinib 5 or 10 mg twice daily in patients with RA. Response according to Clinical Disease Activity Index (CDAI) was assessed separately in patients who discontinued (no MTX/GC use within 30 days prior to year-3 visit; assessment at month 3/year 3) or initiated (on/before year 3; assessment at initiation and year 3) MTX/GC. RESULTS: By year 3, among patients receiving background MTX at baseline, 186/1608 (11.6%) discontinued MTX, and 319/1434 (22.2%) patients receiving GC at baseline discontinued GC. Overall, 70.4/69.1% of patients who discontinued/continued MTX and 72.7/65.9% who discontinued/continued GC achieved CDAI remission or low disease activity (LDA) at year 3. Month 3 remission/LDA rates were maintained at year 3 in the majority of patients, irrespective of MTX/GC discontinuation/continuation. By year 3, 6.2% of patients receiving tofacitinib without MTX at baseline had initiated concomitant MTX, and 25.1% receiving tofacitinib without GC initiated GC; 69.0% and 45.4% initiating MTX or GC, respectively, had a CDAI-defined incomplete response prior to initiation. RA signs/symptoms improved following MTX initiation; only modest improvement was observed with GC initiation. CONCLUSIONS: Patients achieving remission/LDA with tofacitinib may discontinue MTX or GC and maintain treatment response. Patients with an incomplete response may benefit from adding concomitant MTX.

30546249 | Sympathetic skin response in patients with systemic sclerosis and rheumatoid arthritis. | 2018 | BACKGROUND: Sympathetic skin response (SSR) is a technique to assess the sympathetic cholinergic pathways. Sympathetic dysfunction may participate in the development of pain, which is the major complaint in patients with systemic sclerosis (SSc) and rheumatoid arthritis (RA). OBJECTIVES: In this study, we aimed to assess the autonomic dysfunction in patients with (SSc) and (RA) using SSR as a simple neurophysiologic test. METHODS: Palmar SSR to median nerve electrical stimulation was recorded in 21 patients with SSc, 39 patients with RA, and in 60 healthy age and sex-matched control subjects. RESULTS: Palmar SSR to median nerve stimulation (of SSc patients and RA patients) shows significantly delayed latency and reduced amplitude in comparison to the control group. SSR of SSc patients has significantly delayed latency and reduced amplitude when compared to RA patients. Moreover, six SSc patients have delayed SSR in spite of the absence of manifestations of polyneuropathy. CONCLUSIONS: Patients with SSc and RA have features of autonomic dysfunction with more affection of SSc patients. | |
30305912 | Increased alloreactive and autoreactive antihuman leucocyte antigen antibodies associated | 2018 | OBJECTIVES: Rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) disproportionately affect women during and following childbearing years. Antihuman leucocyte antigen (HLA) alloantibody responses are common in healthy parous women, and as these diseases are both linked with HLA and immune dysregulation, we sought to evaluate anti-HLA antibodies in RA and SLE. METHODS: Anti-HLA antibodies were measured among parous SLE cases (n=224), parous RA cases (n=202) and healthy parous controls (n=239) and compared with each other as well as with nulliparous female and male controls. Antibody specificities were identified and compared against subject HLA types to determine autoreactivity versus alloreactivity. The association of anti-HLA antibodies with clinical outcomes was evaluated. RESULTS: Levels and frequencies of anti-HLA antibodies were significantly higher among parous females with SLE (52%) or RA (46%) compared with controls (26%), and anti-HLA antibodies were also found among nulliparous females and males with SLE and RA. Autoreactive anti-HLA antibodies were observed among SLE and RA antibody-positive subjects, but not healthy controls, with the highest frequency of autoreactive anti-HLA antibodies found in the SLE subjects. Higher levels of anti-HLA antibodies were associated with nephritis among the nulliparous SLE cases (p<0.01). The presence of anti-class I HLA antibodies was associated with younger age at diagnosis among both the RA and SLE nulliparous cases. CONCLUSIONS: Both autoreactive and alloreactive anti-HLA antibodies were found at high levels in RA and SLE subjects. These occurred even in the absence of alloexposure, particularly among SLE subjects and may be linked with disease severity. | |
29984038 | Role of IL-32 Gamma on Bone Metabolism in Autoimmune Arthritis. | 2018 Jun | IL-32 acts as a pro-inflammatory cytokine by inducing the synthesis of inflammatory molecules as well as promoting the morphological changes involved in the transformation of monocytes into osteoclasts (OCs). Evaluation of the functions of IL-32 has mainly focused on its inflammatory properties, such as involvement in the pathogenesis of various autoimmune diseases. Recently, IL-32 was shown to be involved in bone metabolism, in which it promotes the differentiation and activation of OCs and plays a key role in bone resorption in inflammatory conditions. IL-32γ also regulates bone formation in conditions such as ankylosing spondylitis and osteoporosis. In this review, we summarize the results of recent studies on the role of IL-32γ in bone metabolism in inflammatory arthritis. | |
31453514 | Falls, fear of falling, and associated factors in ambulatory patients with rheumatoid arth | 2018 Sep | OBJECTIVES: This study aims to compare fall history and fear of falling (FOF) in patients with rheumatoid arthritis (RA) and healthy controls and to evaluate associated factors for fall risk and FOF in patients with RA. MATERIALS AND METHODS: Between March 2016 and July 2016, a total of 120 patients with RA and 60 age- and sex-matched healthy volunteers were included in the study. The presence of FOF (Yes/No), fall history, and the number of falls within the past 12 month were questioned. All participants were assessed with the Falls Efficacy Scale-International (FES-I), 10 Meter Walk Test (10MWT), One-Leg Stand Test (OLST), Berg Balance Scale (BBS), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI). Pain Severity and Patient Global Assessment (PGA) by Visual Analog Scale (VAS), disability by the Health Assessment Questionnaire (HAQ), and disease activity by Disease Activity Score in 28 joints (DAS28) were evaluated in patients with RA. RESULTS: There was no statistically difference between the RA patients and healthy controls in terms of presence of fall history, while the presence of FOF and FES-I scores were significantly higher in the RA patients (p<0.05). In the patient group, the FES-I score was positively correlated with pain VAS, PGA, DAS-28, HAQ, BAI, BDI, and 10MWT and negatively BBS and OLST (p<0.05). The number of falls, HAQ, BBS, and BDI scores were found to be significant independent risk factors affecting variations in the FES-I scores (p<0.001). CONCLUSION: Fear of falling seems to be an important problem in patients with RA, and patients without fall history may also have FOF. The most important factors associated with FOF were impaired balance, increased disability and depression, and number of falls in RA patients. Strategies for preventing falls, maintaining balance, improving emotional status and against FOF are of utmost importance in patients with RA. | |
30293218 | Real-world Comparative Effectiveness of Tocilizumab Monotherapy vs. Tumor Necrosis Factor | 2018 Dec | INTRODUCTION: Controlled clinical studies have shown that the efficacy of tocilizumab (TCZ) monotherapy is superior to that of tumor necrosis factor inhibitor (TNFi) monotherapy and comparable to that of TCZ plus methotrexate (MTX) for the treatment of rheumatoid arthritis (RA). This study compared the real-world effectiveness of TCZ monotherapy vs. TNFis plus MTX in US patients with RA. METHODS: TCZ-naïve patients from the Corrona RA registry with prior exposure to ≥ 1 TNFi who initiated TCZ monotherapy or TNFi + MTX were included. Outcomes included mean change in Clinical Disease Activity Index (CDAI), achievement of low disease activity (LDA; CDAI ≤ 10), achievement of modified American College of Rheumatology (mACR) 20/50 responses, and mean change in modified Health Assessment Questionnaire (mHAQ) at 6 months. Patients initiating TNFi + MTX were grouped by MTX dose (≤ 10 mg; > 10 to ≤ 15 mg; > 15 to ≤ 20 mg; > 20 mg); outcomes in each group were compared with TCZ monotherapy using trimmed populations (excluding patients outside the propensity score distribution overlap). RESULTS: Patients in all groups experienced improvement in CDAI at 6 months (mean change, - 6.9 to - 9.7), with no significant differences between the TCZ monotherapy and TNFi + MTX groups. Achievement of LDA and mACR responses at 6 months were comparable between the TCZ monotherapy and TNFi + MTX groups; overall, 26.8-38.0% of patients achieved LDA, 24.3-37.6% achieved mACR20 response and 13.2-20.8% achieved mACR50 response. The mean change in mHAQ at 6 months was - 0.1 in all groups. CONCLUSIONS: In this real-world population of US patients with RA who had prior TNFi exposure, there was no evidence of a difference in the effectiveness of TCZ monotherapy compared with that of TNFi + MTX, regardless of MTX dose, at 6 months for improving RA disease activity.

29317823 | European perspective on the management of rheumatoid arthritis: clinical utility of tofaci | 2018 | Xeljanz(®) (tofacitinib) is an oral small-molecule inhibitor that reversibly inhibits Janus-activated kinase (JAK)-dependent cytokine signaling, thus reducing inflammation. As a result of these mechanisms, effects on the immune system such as a moderate decrease in the total lymphocyte count, a dose-dependent decrease in natural killer (NK) cell count, and an increase in B-cell count have been observed. Therefore, tofacitinib provides an innovative approach to modulating the immune and inflammatory responses in patients with rheumatoid arthritis (RA), which is especially important in individuals who do not respond to tumor necrosis factor inhibitors or show a loss of response over time. The aim of this article was to review studies on the pharmacology, mode of action, pharmacokinetics, efficacy, and safety of tofacitinib in patients with RA. Tofacitinib has been shown to reduce symptoms of RA and improve the quality of life in the analyzed groups of patients. Moreover, it showed high efficacy and an acceptable safety profile in Phase III randomized clinical trials on RA and was the first JAK inhibitor approved by the US Food and Drug Administration (FDA) and European Medicines Agency (EMA) in the RA therapy, thus providing a useful alternative treatment strategy. Randomized controlled studies revealed a significant benefit over placebo in efficacy outcomes (American College of Rheumatology [ACR] 20 and ACR50 response rates); accordingly, clinically meaningful improvements in patient-related outcomes compared with placebo have been reported. The safety profile seems acceptable, although some severe adverse effects have been observed, including serious infections, opportunistic infections (including tuberculosis and herpes zoster), malignancies, and cardiovascular events, which require strict monitoring irrespective of the duration of tofacitinib administration. As an oral drug, tofacitinib offers an alternative to subcutaneous or intravenous biologic drugs and should be recognized as a more convenient way of drug administration. | |
29626254 | CUL4B promotes the pathology of adjuvant-induced arthritis in rats through the canonical W | 2018 Jun | This work aims to discuss the possibility that disordered CUL4B was involved in the pathogenesis of adjuvant-induced arthritis (AIA) in rats. Synovium and FLS from AIA rats both showed increased CUL4B and β-catenin, and up-regulated CUL4B enhanced the canonical Wnt signaling by targeting the GSK3β. Increased CUL4B promoted the FLS abnormal proliferation, activated the secretion of IL-1β and IL-8, and promoted the production of AIA pathology gene MMP3 and fibronectin. Furthermore, miR-101-3p was significantly down-regulated in AIA rats compared with controls, and transfection of AIA FLS with miR-101-3p mimics significantly down-regulated the CUL4B expression, whereas transfection with miR-101-3p inhibitors resulted in an opposite observation. The dual-luciferase reporter assay confirmed that the CUL4B was a direct target of miR-101-3p, and further analysis suggested that lowly expressed miR-101-3p contributed to disordered CUL4B activating the canonical Wnt signaling pathway and further promoting the development of AIA rats. Thus clarification of the CUL4B roles in the pathogenesis of AIA rats and corresponding mechanisms will contribute to the disease diagnosis and treatment for rheumatoid arthritis (RA) patients. KEY MESSAGES: CUL4B expression is up-regulated in synovium and FLS from AIA rats. Increased CUL4B promotes the canonical Wnt signaling. Increased CUL4B promotes the pathogenesis of AIA rats. Decreased miR-101-3p contributes to disordered CUL4B. | |
29723540 | TNFα-dependent anhedonia and upregulation of hippocampal serotonin transporter activity i | 2018 Jul 15 | The serotonin transporter (SERT) facilitates high affinity reuptake of 5-HT from the extracellular fluid and dysregulation of transporter function has been implicated in a range of mood disorders including depression. Recent studies have linked immune system activation to depression as well as to altered serotonin transporter activity. Advancing previous studies, which have mainly focussed on acute effects of immune system activation, in this study we used collagen-induced arthritis (CIA) in mice as a model of chronic inflammatory disease, to investigate the effect of prolonged inflammation on brain SERT function and behaviour. We found that 5-6 weeks after immunisation, CIA mice display anhedonia, a core depression-like behaviour. Behavioural symptoms are temporally correlated with a region-specific upregulation of SERT activity in the hippocampus, which occurs at a post-translational level and is independent of SERT trafficking. Kinetic analysis of 5-HT uptake revealed that the elevation of transporter activity is due to an increase in 5-HT transport capacity (V(max)) with no change in apparent K(m) values, suggesting that different regulatory mechanisms govern SERT modulation under chronic versus acute inflammatory conditions. Protein expression of tumour necrosis factor receptor 1 (TNFR1) was specifically upregulated in the hippocampus of CIA mice, indicating altered TNFα signalling. Anti-TNFα treatment using etanercept not only diminished joint inflammation, but also prevented the development of anhedonia and the upregulation of SERT activity in the hippocampus, suggesting a key role for TNFα signalling in brain function regulation in this disease model. Our study provides novel insight into molecular mechanisms underlying mood symptoms in chronic inflammatory diseases, with particular relevance to rheumatoid arthritis. | |
31070537 | Mangosteen ethanol extract alleviated the severity of collagen-induced arthritis in rats a | 2018 Dec | CONTEXT: Garcinia mangostana Linn. (Guttiferae) pericarp is used as a traditional medicine in South Asia to treat inflammatory diseases. OBJECTIVE: This study investigates therapeutic effects of G. mangostana pericarp ethanol extract (MAN) on collagen-induced arthritis (CIA) and interactions with methotrexate in vivo. MATERIALS AND METHODS: Male Sprague-Dawley rats with CIA were treated with MAN (0.5 g/kg/day), methotrexate (0.5 mg/kg, bw) or combination of both for 36 days, respectively (n = 8/group). Another eight healthy and CIA rats served as normal and model control, respectively. Therapeutic effects were evaluated based on paw edema and arthritis score during the experiment and serological markers at the end of the study period. Histological and radiological examinations were used to assess joint destructions. The immune status was investigated by immunohistochemistry and flow cytometry. RESULTS: All treatments decreased the arthritis score and paw inflammation in CIA rats. Combination regimen significantly reduced anti-cyclic citrullinated peptide antibody in CIA rats to 85.83% (p < 0.05) and notably alleviated synovial hyperplasia and cartilage degradation in joints. Different from methotrexate, MAN significantly augmented CD25(+) cells distribution (from 2.72 to 3.35%) and IL-10 secretion (from 202.4 to 241.2 pg/mL) in CIA rat blood. Meanwhile, MAN induced a greater IL-17 decrease and a FOXP3 increase in immune organs than MTX. Reduced TLR4 and IL-17 expression and elevated FOXP3 expression in joints also occurred under MAN treatment. CONCLUSIONS: MAN protected joints from destruction in CIA rats and exerted synergistic effects with methotrexate by improving immune microenvironment. The combination regimen could bring additional benefits to rheumatoid arthritis patients. | |
30632931 | Efficacy of infliximab as a switched biologic in rheumatoid arthritis patients in daily cl | 2018 Dec | To assess the efficacy and safety of switching to infliximab (IFX) from other biological disease-modifying anti-rheumatic drugs (bDMARDs) among Japanese patients with rheumatoid arthritis (RA) in daily practice. We examined 24 consecutive RA patients who had not achieved low disease activity (LDA) as the disease activity score-28 for rheumatoid arthritis with erythrocyte sedimentation rate (DAS28-ESR) despite previous bDMARD therapy in this cohort study. We attempted to determine predictive variables that are associated with achieving DAS28-ESR LDA at 22 weeks post-IFX introduction, by performing univariate analysis. The median DAS28-ESR at baseline was 5.41. Sixteen patients (66.7%) had been treated with a tumor necrosis factor inhibitor (TNF-i), and the other eight patients (33.3%) received a non-TNF-i (abatacept or tocilizumab). Nine patients (37.5%) achieved LDA or remission at 22 weeks. Univariate analyses showed that the variable to predict LDA achievement at 22 weeks was tender joints (>8 counts) at baseline (adjusted odds ratio, 0.10; 95% confidence interval, 0.01-0.63; p = .02). Nine adverse events were observed during the study period, and infection requiring hospitalization was observed in one patient. Switching to IFX is effective to achieve LDA or remission for RA patients refractory to bDMARDs. | |
30622736 | Performance of the Expanded Cardiovascular Risk Prediction Score for Rheumatoid Arthritis | 2018 | BACKGROUND: Cardiovascular (CV) risk stratification for patients with rheumatoid arthritis (RA) should facilitate evidence-based management. Prior work has derived an internally validated a CV risk score, the Expanded Cardiovascular Risk Prediction Score for Rheumatoid Arthritis (ERS-RA), using US data. The aim of this study was to perform an external validation among unselected patients with RA from Europe. METHODS: Three large, partially overlapping, cohorts of patients with RA from the Swedish Rheumatology Quality register were identified for external validation, two with information on smoking and two with close to 10 years of median follow-up. The 10 -year rate of first CV events was assessed using the Kaplan-Meier method. The performance of ERS-RA was assessed using C-index and comparisons of observed versus predicted risks. RESULTS: The C-index for ERS-RA varied across the three RA cohorts, from 0.75 to 0.78. Predicted risks corresponded well to observed risks among individuals with ≤10 % observed 10- year CV risk, but underestimated risk in individuals with a higher observed risk. In the absence of data on smoking, ERS-RA underestimated the CV risk by 3.3%, whereas in the cohorts including data on smoking, the calibration was within 1% (0.06% and 0.7%). In the clinically relevant risk intervals (<5%, 5.0%-<7.5%, 7.5%-<10%), ERS-RA performed well. CONCLUSIONS: In an unselected Swedish population with RA, ERS-RA performed well, although the 10-year CV risk was underestimated in high-risk groups and in the absence of data on smoking. ERS-RA could be considered as a risk stratification tool for targeted preventive interventions in clinical rheumatology practice. | |
29657830 | Conversion to seronegative status after abatacept treatment in patients with early and poo | 2018 | OBJECTIVE: To evaluate the effects of the T-cell costimulation blocker abatacept on anti-citrullinated protein antibodies (ACPA) and rheumatoid factor (RF) in early rheumatoid arthritis (RA), and associations between changes in serological status and clinical response. METHODS: Post hoc analysis of the phase III AGREE study in methotrexate (MTX)-naïve patients with early RA and poor prognostic factors. Patients were randomised to abatacept (~10 mg/kg intravenously according to weight range) or placebo, plus MTX over 12 months followed by open-label abatacept plus MTX for 12 months. Autoantibody titres were determined by ELISA at baseline and months 6 and 12 (double-blind phase). Conversion to seronegative status and its association with clinical response were assessed at months 6 and 12. RESULTS: Abatacept plus MTX was associated with a greater decrease in ACPA (but not RF) titres and higher rates of both ACPA and RF conversion to seronegative status versus MTX alone. More patients converting to ACPA seronegative status receiving abatacept plus MTX achieved remission according to Disease Activity Score in 28 joints (C-reactive protein) or Clinical Disease Activity Index than patients who remained ACPA seropositive. Patients who converted to ACPA seronegative status treated with abatacept plus MTX had a greater probability of achieving sustained remission and less radiographic progression than MTX alone or patients who remained ACPA seropositive (either treatment). CONCLUSIONS: Treatment with abatacept plus MTX was more likely to induce conversion to ACPA/RF seronegative status in patients with early, erosive RA. Conversion to ACPA seronegative status was associated with better clinical and radiographic outcomes. TRIAL REGISTRATION NUMBER: NCT00122382. | |
29987858 | Methotrexate-associated lymphoproliferative disorders with angioimmunoblastic T-cell lymph | 2018 Jul 10 | Although gamma heavy chain disease (γ-HCD) lesions occasionally morphologically resemble angioimmunoblastic T-cell lymphoma (AITL), no association has been described in detail due to the rarity of the disease. In this report, we present a rare manifestation of methotrexate (MTX)-associated lymphoproliferative disorders (LPDs) with AITL-like features accompanied by γ-HCD in a 75-year-old man with rheumatoid arthritis (RA). A biopsy specimen was evaluated using immunohistochemistry, clonal analyses of immunoglobulin V(H) and T-cell receptor γ gene rearrangements by polymerase chain reaction, and Sanger sequencing for confirmation of the structure of deleted γ-HCD clones. The histological features characterized by proliferation of CD4- and PD-1-positive medium-sized T cells and arborizing high endothelial venules together with numbers of small lymphocytes, eosinophils, plasma cells, and histiocytes in the background mimicked those of AITL, but did not completely fulfill the diagnostic criteria. Clonal analysis demonstrated that the specimen contained multiple LPDs of both B-cell and T-cell lineages. Sequence analysis confirmed the co-existence of a clone responsible for production of the abnormal heavy chain. This report provides new insights into the pathology of γ-HCD. Multiple host-derived factors (e.g., RA and/or use of MTX) may be responsible for the occurrence of LPDs of multiple lineages within a single lymph node. | |
30501854 | Cavitary pulmonary nodules in rheumatoid arthritis; case reports and review of the literat | 2018 Mar | Rheumatoid nodules are the most common pulmonary manifestations of rheumatoid arthritis (RA) and are usually asymptomatic. In rare cases, they progress cavitary formation and cause severe clinical symptoms because of disease activity, infectious diseases, and other etiologies. The determination of clinical and histopathological features may be helpful for differential diagnosis in patients with RA with cavitary pulmonary nodules. Herein, we report two female patients with RA with cavitary pulmonary nodules and aim to obtain more detail data by means of reviewing previously reported cases. | |
28268160 | Primary Sjögren's syndrome and bronchiolitis. An unusual association. | 2018 Jul | Sjögren's syndrome (SS) is a systemic autoimmune disease that mainly affects the exocrine glands. It has been reported that the association between SS and respiratory involvement occurs in 11% and 45% of cases, and can be the initial manifestation of the disease. The diagnosis is based on the integration of clinical, immunological and histopathological criteria. This paper examines a 58-year-old man with SS, severe dyspnea and recurrent exacerbations associated with bronchiolitis-bronchiectasis. The absence of anti-Ro and anti-La antibodies associated with severe bronchiolitis is a clinical presentation that is poorly characterized in this group of patients; moreover, how to treat them remains unclear. | |
29763424 | Prevalence of primary Sjögren's syndrome in patients undergoing evaluation for pulmonary | 2018 | BACKGROUND: The prevalence of pulmonary arterial hypertension (PAH) in primary Sjögren's syndrome (SS) had been reported to be rare. However, recent studies using echocardiography as a screening method showed conflicting results, and the true prevalence is still unclear. Since diagnosing primary SS is difficult because of its heterogeneous nature, a number of patients with primary-SS-associated PAH may be misdiagnosed with idiopathic PAH, losing their chance to undergo immunosuppressive therapy. Therefore, we sought to elucidate the prevalence of primary SS among patients who initially present with PAH. METHODS: From our prospective institutional PAH database, 40 consecutive patients without any obvious cause of PAH at the time of PAH diagnosis were identified. We retrospectively evaluated the prevalence of primary SS diagnosed during or after the initial assessment of PAH. RESULTS: During the initial assessment, one patient was diagnosed with primary-SS-associated PAH. Among the 25 patients who were initially diagnosed with idiopathic PAH, five were diagnosed with primary SS during their course of the disease. Of the five patients, three had key signs suggesting primary SS and were probably underdiagnosed at the time of initial evaluation. The remaining two patients, who were finally diagnosed with primary SS, did not have any specific signs suggesting primary SS at the time of initial evaluation but showed positive conversion of their autoantibodies during the course of PAH. CONCLUSION: The prevalence of primary-SS-associated PAH may be relatively high among patients who undergo initial evaluation for PAH. Furthermore, primary-SS-associated PAH may be underdiagnosed with routine evaluation for the primary cause of PAH. Clinicians should pay specific attention and carefully evaluate the possibility of primary SS in patients with PAH. |
