28608433 | Performances of Clinical Disease Activity Index (CDAI) and Simplified Disease Activity In | 2018 Nov | BACKGROUND/PURPOSE: To compare the performance of Disease Assessment Score of 28 joints - C-reactive protein (DAS-28-CRP), Clinical Disease Activity Index (CDAI) and Simplified Disease Activity Index (SDAI) composite measures to assess status of patients with rheumatoid arthritis (RA) on methotrexate, versus DAS-28 CRP as the gold standard. METHODS: One hundred and thirty-five patients with RA as per the 2010 American College of Rheumatology/European League Against Rheumatism criteria were included in the prospective study. The disease activity was assessed at baseline and at every 6 weeks for 24 weeks, by DAS-28-CRP, CDAI and SDAI. Patients were divided into groups of remission, low, moderate and high activity on the basis of predefined cut-offs for DAS-28-CRP, CDAI and SDAI. A Spearman correlation between composite measures and inter-group comparison of the measures was performed. RESULTS: There was an excellent positive correlation between DAS-28-CRP and CDAI (linear weighted κ baseline - 0.545), DAS-28 CRP and SDAI (linear weighted κ - 0.689) at baseline. There was moderate agreement between DAS-28-CRP and CDAI (linear weighted κ final visit - 0.458) at final visit. There was moderate correlation between SDAI and DAS-28-CRP at final visit (linear weighted κ - 0.470). However, correlation between CDAI versus SDAI remained excellent at baseline and final visit. Patients in remission as per DAS-28-CRP had significantly more residual disease activity compared to SDAI and CDAI remission criteria. CONCLUSION: The study shows an excellent strong positive correlation between DAS-28-CRP, CDAI and SDAI at initial evaluation but not at final visit. SDAI- and CDAI-based remission criteria seem to be better than DAS-28-CRP-based remission criteria. | |
30079994 | The effect of caveolin-1 knockdown on interleukin-1β-induced chemokine (C-C motif) ligand | 2018 Nov | BACKGROUND: Rheumatoid arthritis (RA) is a chronic autoimmune disease leading to destructive changes in peripheral joints and their irreversible deformity. The influx of chemoattractant-mediated inflammatory cells to the joints is one of the main features of RA. OBJECTIVES: The aim of this study was to investigate the effect of a knockdown of caveolin-1 (CAV1), a known regulator of multiple cell signaling pathways, on chemokine (C-C motif) ligand 2/monocyte chemoattractant protein-1 (CCL2/MCP-1) expression in synovial fluid-derived fibroblast-like synoviocytes (sfd-FLSs) obtained from patients with RA. MATERIAL AND METHODS: Primary cell cultures of sfd-FLSs were established from RA synovial fluids. Cells were transiently transfected with small interfering RNA (siRNA) specific for CAV1, and then incubated with interleukin (IL)-1β to induce CCL2 expression. The expression levels of CAV1 and CCL2 were assessed at transcript level, using quantitative polymerase chain reaction (qPCR) and at protein level by enzyme-linked immunosorbent assay (ELISA) and western blotting analysis. RESULTS: A transient CAV1 knockdown in sfd-FLSs resulted in a decrease in the IL-1β-induced CCL2 mRNA expression level vs non-transfected cells and cells transfected with non-targeting siRNA. The concentration of secreted CCL2 was not affected significantly. CONCLUSIONS: Our study demonstrates that CCL2 expression in sfd-FLSs is CAV1-dependent, but only at transcript level. As the function of CAV1 has not been unequivocally determined, more studies are needed to confirm the role of CAV1 in inflammatory processes related to RA. | |
29366644 | What does power Doppler signal indicate in rheumatoid synovitis? A point of view from syno | 2018 Apr | To clarify the nature of power Doppler (PD) signals in rheumatoid synovium and to establish the connection between PD signals and active inflammation using synovial histopathology. Ten adult patients (median age 57.0 years, 9 women and one man) with rheumatoid arthritis (RA) were enrolled and received ultrasound (US) examinations. US-guided synovial biopsies using core needle were performed in 7 knees, 2 wrists and one elbow. Each patient had one joint biopsied. In total, 11 synovial specimens were obtained for hematoxylin and eosin staining and histopathologic examinations. The US examinations revealed prominent synovial hypertrophy in all biopsied joints. Six synovial specimens were PD-positive (from 3 knees, 2 wrists and 1 elbow) while 5 synovial specimens were PD-negative (from 5 knees). In comparison with the PD-negative synovial specimens, the PD-positive synovial specimens had significantly more lymphocyte infiltration, vessel proliferation and lining hyperplasia on histologic examination. There was no significant difference in fibrin exudate and stromal fibrosis between the PD-positive and the PD-negative synovial specimens. PD signals in rheumatoid synovium indicate active inflammation and vascularization supported by synovial histopathology. Our study establishes the connection between synovial PD signals and active synovitis in RA. | |
29731458 | [Diagnosis and treatment of rheumatoid arthritis:toward the best practice. New therapeutic | 2018 | For rheumatoid arthritis, biological DMARDs, such as TNF inhibitors, and JAK inhibitors have been widely used as a targeted therapy. These drugs show higher effect compared to conventional therapy. New molecular targeted drugs are also developing. Clinical trials of anti-GM-CSF and -chemokine monoclonal antibodies, and inhibitors of intracellular signals are underway. We anticipate new drugs with higher efficacy and safety. | |
29185111 | Factors influencing spinal sagittal balance, bone mineral density, and Oswestry Disability | 2018 Feb | PURPOSE: To identify the factors influencing spinal sagittal alignment, bone mineral density (BMD), and Oswestry Disability Index (ODI) outcome measures in patients with rheumatoid arthritis (RA). METHODS: We enrolled 272 RA patients to identify the factors influencing sagittal vertical axis (SVA). Out of this, 220 had evaluation of bone mineral density (BMD) and vertebral deformity (VD) on the sagittal plane; 183 completed the ODI questionnaire. We collected data regarding RA-associated clinical parameters and standing lateral X-ray images via an ODI questionnaire from April to December 2012 at a single center. Patients with a history of spinal surgery or any missing clinical data were excluded. Clinical parameters included age, sex, body mass index, RA disease duration, disease activity score 28 erythrocyte sedimentation rate (DAS28-ESR), serum anti-cyclic citrullinated peptide antibody, serum rheumatoid factor, serum matrix metalloproteinase-3, BMD and treatment type at survey, such as methotrexate (MTX), biological disease-modifying anti-rheumatic drugs, and glucocorticoids. We measured radiological parameters including pelvic incidence (PI), lumbar lordosis (LL), and SVA. We statistically identified the factors influencing SVA, BMD, VD, and ODI using multivariate regression analysis. RESULTS: Multivariate regression analysis showed that larger SVA correlated with older age, higher DAS28-ESR, MTX nonuse, and glucocorticoid use. Lower BMD was associated with female, older age, higher DAS28-ESR, and MTX nonuse. VD was associated with older age, longer disease duration, lower BMD, and glucocorticoid use. Worse ODI correlated with older age, larger PI-LL mismatch or larger SVA, higher DAS28-ESR, and glucocorticoid use. CONCLUSIONS: In managing low back pain and spinal sagittal alignment in RA patients, RA-related clinical factors and the treatment type should be taken into consideration. | |
30701892 | DICER and DROSHA gene expression in peripheral mononuclear blood cells from rheumatoid art | 2018 May 11 | AIM: The aim of this research was studying the level of DROSHA and DICER genes expression in peripheral mononuclear blood cells (PBMC) in rheumatoid arthritis (RA) patients under methotrexate therapy. MATERIALS AND METHODS: 82 people (from 45 to 70 years) enrolled in this study were divided into 3 groups (the first one - healthy donors (n=33 median age 49.93±1.87); the second group - rheumatoid arthritis patients without any therapy (n=15; median age 57.28±15.18) and the third group (n=34; median age 60.88±9.02) - rheumatoid arthritis patients who treated at least 4 weeks with methotrexate therapy (10-20 mg/week). The DICER and DROSHA genes expression level was determined by real-time PCR. RESULTS: The number of DICER gene transcripts in PBMC in rheumatoid arthritis patients without therapy as in RA patients treated with methotrexate was reduced in comparison with the healthy donors (p<0.001 and p>0.05 respectively). The level of DROSHA gene expression in PBMC was not significantly different in all groups enrolled in this study (p>0.05). CONCLUSION: Our findings suggest that that the DICER gene expression level in perifheral mononuclear blood cells decreased with the development of rheumatoid arthritis. Methotrexate doesn't influence on the mRNA level of this gene. | |
29271811 | Surgically Induced Scleral Necrosis in a Patient With Rheumatoid Arthritis After AGV Impla | 2018 Mar | INTRODUCTION: Surgically induced scleral necrosis (SINS) is a rare entity that has till date not been reported in a patient of glaucoma undergoing Ahmed glaucoma valve (AGV) implantation. METHODS: We present a case of primary open-angle glaucoma who underwent AGV implantation followed by development of scleral necrosis, involving both the scleral patch graft and host sclera. After failure of surgical and medical management, AGV had to be explanted. The patient was diagnosed with rheumatoid arthritis and had to be treated with steroids and azathioprine for the same. RESULTS: SINS is a potentially disastrous complication of ocular surgery that can occur in patients with systemic diseases like rheumatoid arthritis and requires aggressive management to salvage the eye. CONCLUSION: SINS can occur with AGV implantation. Treatment may require aggressive medical and surgical intervention. It is imperative to evaluate patients for systemic illness before planning an AGV implant. | |
29333090 | Gene and Protein Expression Profiles in a Mouse Model of Collagen-Induced Arthritis. | 2018 | The risk of rheumatoid arthritis (RA), an autoimmune disease, in the elderly population increases along with that of atherosclerosis, cardiovascular disease, type 2 diabetes, and Alzheimer's disease. Identifying specific biomarkers for RA can clarify the underlying molecular mechanisms and can aid diagnosis and patient care. To this end, the present study investigated the genes and proteins that are differentially expressed in RA using a mouse collagen-induced arthritis (CIA) model. We performed gene microarray and proteome array analyses using blood samples from the mice and found that 50 genes and 24 proteins were upregulated and 48 genes were downregulated by more than 2-fold in the CIA model relative to the control. The gene microarray and proteome array results were validated by evaluating the expression levels of select genes and proteins by real-time PCR and western blotting, respectively. We found that the level of integrin α2, which has not been previously reported as a biomarker of RA, was significantly increased in CIA mice as compared to controls. These findings provide a set of novel biomarkers that can be useful for diagnosing and evaluating the progression of RA. | |
30001787 | Update on Cardiovascular Disease Risk in Patients with Rheumatic Diseases. | 2018 Aug | Cardiovascular disease (CVD) risk is 1.5-fold higher in rheumatoid arthritis (RA), partly due to subclinical atherosclerosis that develops before the diagnosis of RA. Dyslipidemia in RA is better quantified by lipoproteins and apolipoproteins than by cholesterol levels. Current risk factors likely underestimate CVD risk by underestimating prior risk factor levels. Some of the 2-fold higher risk of heart failure and total mortality in RA may be due to myocardial disease caused by inflammation. Per recent recommendations, to reduce CVD risk in RA, control disease activity, reduce inflammation, and aggressively treat CVD risk factors. | |
29491299 | Adult T-cell Leukemia/Lymphoma as a Methotrexate-associated Lymphoproliferative Disorder i | 2018 Jul 15 | The patient was a 74-year-old Japanese woman with rheumatoid arthritis (RA) who developed generalized lymphadenopathy with elevated levels of lactase dehydrogenase (LD), and soluble IL-2 receptor (sIL-2R). She was found to be positive for anti-human T-cell leukemia virus type 1 (HTLV-1) antibodies. Her symptoms and laboratory abnormalities spontaneously regressed after the cessation of methotrexate (MTX), suggesting that she had an MTX-associated lymphoproliferative disorder; however, her lymphadenopathy appeared again approximately 14 months later with LD and sIL-2R elevation. A histopathological analysis and Southern blotting of a lymph node biopsy specimen for HTLV-1 provirus supported the diagnosis of adult T-cell leukemia/lymphoma (ATL) (lymphoma type). These data confirmed that an HTLV-1 positive RA patient may develop ATL. | |
28036154 | Identifying barriers to the care of the rheumatoid hand in China: comparing attitudes of r | 2018 Nov | AIM: In China, hand surgeons treat fewer rheumatoid arthritis (RA) patients compared to other countries. We investigated whether physician and surgeon knowledge, attitudes and practices regarding RA hand deformities reflect current evidence and may contribute to the low utilization of surgery. METHOD: We surveyed hand surgeons and rheumatologists at three tertiary hospitals in Beijing, China. Questionnaires were developed from literature and expert review to assess their knowledge, attitudes and practice patterns related to rheumatoid hand surgery. RESULTS: Thirty-five hand surgeons and 59 rheumatologists completed the survey. Roughly one-third felt that the rheumatologists and hand surgeons agree on how to manage RA hand deformities. One-fifth of rheumatologists and 29% of hand surgeons believed that drug therapy can correct hand deformities, which contradicts current evidence. Likewise, 30% and 14%, respectively, recommended surgery for early-stage hand sequelae that do not meet current indications for surgery. Over 80% of surgeons and rheumatologists had no exposure to the other specialty during training and felt their training on the treatment of rheumatoid hand deformities was inadequate. CONCLUSION: Although we found similar interspeciality disagreement in China as is seen in the United States, there appears to be less interaction through training and consultations. Our results also indicate potential deficits in training and unawareness of evidence and indications for rheumatoid hand surgery. These findings help to explain why surgery for rheumatoid hand deformities is rare in China; doctors have fewer opportunities to collaborate across specialties and may not be able to select appropriate candidates for surgery. | |
28743593 | Should radiographic progression still be used as outcome in RA? | 2018 Jan | Radiographs of hands and feet are traditionally the images that are used to assess structural damage progression in drug trials in patients with rheumatoid arthritis, aiming at proving the disease modifying capacity of a drug. Although treatment has largely improved over the past decade and consequently radiographic progression is limited in control arms in clinical trials, recent trials are still able to show inhibition of structural progression by new drugs. The requirements for the successful use of radiographic progression as an outcome in rheumatoid arthritis trials will be discussed in this paper. | |
29437229 | IL-27: a double agent in the IL-6 family. | 2018 Jul | The cytokine interleukin (IL)-6 is a major therapeutic target for the treatment of various inflammatory and autoimmune diseases. While IL-6 receives considerable attention in studies of innate and adaptive immunity, the IL-6-related family member IL-27 is recognized increasingly for its effects on cellular proliferation, differentiation and leucocyte effector functions. Both cytokines activate responses in myeloid and stromal tissue cells, where they direct the transition from innate to adaptive immunity. However, they are identified frequently as lymphokines that control responses in T cells and B cells. In this regard, IL-27 often opposes the action of IL-6. Here, we will review the role of IL-6 and IL-27 in inflammation, with a particular focus on inflammatory arthritis, and discuss their importance in the diagnosis, stratification and treatment of autoimmune disease. | |
29443754 | Multiple extra-articular synovial cysts accompanied by rheumatoid arthritis in the bilater | 2018 Feb | RATIONALE: Synovial cysts are well known in rheumatoid arthritis (RA), and most common in the popliteal fossa. They may produce lots of local symptoms and complaints, which may present initially as an unrelated clinical condition. Few studies have reported multiple extra-articular synovial cysts (MESCs) in the RA patients. Early diagnosis is crucial for patient treatment. PATIENT CONCERNS: A 50-year-old man without any special clinical histories found a soya bean size bump at the left elbow medially, then multiple lumps were found at bilateral elbows and gradually increasing. No pain, no activity, no redness, and swelling. Magnetic resonance imaging (MRI) showed multiple cystic lesions in the bursa and surrounding soft tissue of bilateral elbow joints. In addition, the elbow joint bursa was swollen and the synovial membrane was significantly thickened. DIAGNOSES: The man was diagnosed as RA with multiple extra-articular synovial cysts formation. INTERVENTIONS: The patient was performed tylectomy of the right elbow. Other lumps were punctured and injected with compound betamethasone injection. OUTCOMES: The bumps were reduced in size and the swelling relieved, and the patient was sent to the department of rheumatology and immunology for further treatment. LESSONS: In this case, it is difficult for the diagnosis of RA because of no relative histories and simultaneously multiple cystic lesions in multiple joints. Imaging examinations can show the characteristics of such kind of disease and be very helpful for the diagnosis and differentiate diagnosis. | |
28952654 | Tailored Therapist-guided Internet-based Cognitive-behavioural Treatment for Psoriasis and | 2018 Feb 7 | Chronic somatic conditions, such as psoriasis, arthritis psoriatica and rheumatoid arthritis, have a large impact on patients' lives. Tailored therapist-guided internet-based cognitive-behavioural therapy (ICBT) has been shown to be effective in improving physical and psychological well-being in these patients. Two cases are presented here, in order to provide an in-depth illustration of the course and content of this novel treatment and to investigate the therapeutic alliance in an online treatment. After face-to-face intakes, both patients received therapist-guided ICBT tailored to their specific problems and treatment goals. The treatment resulted in improved physical and psychological well-being and these clinically significant improvements were maintained at 6-month follow-up. In addition, the therapeutic relationship was evaluated positively by both patients and increased further during treatment, indicating an adequate therapeutic working alliance in this online treatment. These case reports show that tailored ICBT may contribute to improved care for patients with chronic somatic conditions. | |
30225702 | Analysis of the Association of TNF -238G>A Gene Polymorphism with the Risk of Rheumatoid A | 2018 Sep | We studied association of the TNF gene -238G>A polymorphism (rs361525) with the risk of rheumatoid arthritis development in the Russian population living in the Republic of Karelia. The influence of rs361525 on the development of rheumatoid arthritis was revealed: genetic predisposition to this disease is associated with the presence of GG genotype. The effect of the genotype on the polymorphic locus of -238G>A on TNF mRNA content was revealed. Increased content of transcripts of this gene is associated with the presence of A allele. | |
30347947 | Seroprevalence of Anti-Citrullinated Protein Antibodies (ACPA) in Patients with Rheumatic | 2018 Apr | OBJECTIVE: To evaluate the prevalence of anti- citrullinated protein antibodies (ACPA) in patients with a variety of rheumatic diseases other than rheumatoid arthritis (RA). METHODS: 144 cases of rheumatic diseases other than rheumatoid arthritis (RA) over a period of 1 year were recruited after consenting and followed up for 2 years. Their serum samples were tested for ACPA. RESULTS: ACPA seropositivity of 9.03% was observed in rheumatic diseases other than RA. CONCLUSION: Whether ACPA seropositivity in non-RA rheumatic diseases indicates a false positive result or an overlap RA syndrome is a mystery yet unsolved. Long term follow ups of these patients will be required to understand the course of rheumatic diseases in relation to ACPA.. | |
30081592 | The Micro-RNA Expression Profiles of Autoimmune Arthritis Reveal Novel Biomarkers of the D | 2018 Aug 5 | Rheumatoid arthritis (RA) is a chronic autoimmune disease of the joints affecting about 0.3â»1% of the population in different countries. About 50â»60 percent of RA patients respond to presently used drugs. Moreover, the current biomarkers for RA have inherent limitations. Consequently, there is a need for additional, new biomarkers for monitoring disease activity and responsiveness to therapy of RA patients. We examined the micro-RNA (miRNA) profile of immune (lymphoid) cells of arthritic Lewis rats and arthritic rats treated with celastrol, a natural triterpenoid. Experimental and bioinformatics analyses revealed 8 miRNAs (miR-22, miR-27a, miR-96, miR-142, miR-223, miR-296, miR-298, and miR-451) and their target genes in functional pathways important for RA pathogenesis. Interestingly, 6 of them (miR-22, miR-27a, miR-96, miR-142, miR-223, and miR-296) were further modulated by celastrol treatment. Interestingly, serum levels of miR-142, miR-155, and miR-223 were higher in arthritic versus control rats, whereas miR-212 showed increased expression in celastrol-treated rats compared with arthritic rats or control rats. This is the first study on comprehensive miRNA expression profiling in the adjuvant-induced arthritis (AA) model and it also has revealed new miRNA targets for celastrol in arthritis. We suggest that subsets of the above miRNAs may serve as novel biomarkers of disease activity and therapeutic response in arthritis. | |
29679167 | Hot joints: myth or reality? A thermographic joint assessment of inflammatory arthritis pa | 2018 Sep | Rheumatoid arthritis is a common inflammatory disease that causes destruction of joints. Accurate recognition of active disease has significant implications in determining appropriate treatment; however, there is significant inter-rater variability in clinical joint assessment. This study aimed to assess the utility of thermographic imaging in the evaluation of inflammatory arthritis activity as an adjunct to clinical assessment. This was a cross-sectional study of 79 subjects recruited from the University of Alberta Outpatient Rheumatology clinic comparing the hand joints of 49 patients with rheumatoid arthritis (RA) diagnosed by American College of Rheumatology (ACR) criteria to 30 healthy volunteers. Convenience sampling of consecutive RA patients was undertaken. The effect of clinical assessment (HAQ and DAS-28) on joint temperature was evaluated using a linear mixed effect model. A thermography camera, FLIR T300 model, 30 Hz, was used to obtain both thermographic and digital images on subjects. Pearson's correlation coefficient was used to assess the correlation of clinical assessments and average joint temperature averaged over all joints. Thermographic analysis did not associate with clinical measures of disease activity. In RA patients, there was no statistically significant relationship between joint temperature and clinical assessment of disease activity including Health Assessment Questionnaire (coefficient estimate - 0.54, p = 0.056), swollen joints (coefficient estimate - 0.09, p = 0.238), or serologic markers of inflammation such as CRP (coefficient estimate - 0.006, p = 0.602) and ESR (coefficient estimate - 0.01, p = 0.503). Evaluation of disease activity requires a multifaceted approach that includes clinical assessment and appropriate imaging. There may be a role for thermography in assessment of larger joints; however, it does not appear to be an effective modality for the small joints of the hand. | |
29866188 | Scleromalacia perforans: a case report. | 2018 Jun 5 | BACKGROUND: Scleromalacia perforans is a rare ocular manifestation of rheumatoid arthritis which can potentially lead to blindness and is a late consequence in the course of the disease. It is an unusual finding for it to be present in a patient with joint pain without any rheumatologic progression of disease. CASE PRESENTATION: We describe a rare case of scleromalacia perforans and orbital inflammatory disease in a 40-year-old Pakistani woman with apparently no associated rheumatologic deformity. It is rare in the sense that we usually see scleromalacia perforans with fixed deformities of rheumatoid arthritis in the hands or progressed systemic complications but not as a starting landmark of disease. She presented to us with pronounced eye manifestation which on further inquiry and investigation was found to be associated with rheumatoid arthritis. There was perforation of left globe on presentation and the right one was preserved. She visited various physicians and ophthalmologists and was treated with topical and systemic antibiotics but ended up losing sight in her left eye. CONCLUSION: We conclude that ocular manifestations, however rare they are, should be foreseen, investigated, and treated in patients with suspected arthritis as the complication is grave and sight threatening. |
