To study the pathogenic importance of the rheumatoid factor (RF) in rheumatoid arthritis (RA) and to identify genes differentially expressed in patients and healthy individuals, total RNA was isolated from peripheral blood mononuclear cells (PBMC) from eight RF-positive and six RF-negative RA...... patients, and seven healthy controls. Gene expression of about 10,000 genes were examined using oligonucleotide-based DNA chip microarrays. The analyses showed no significant differences in PBMC expression patterns from RF-positive and RF-negative patients. However, comparisons of gene expression patterns...

Full Text Available BACKGROUND: To investigate the associations between HLA-DRB1 shared epitope (SE alleles and rheumatoid arthritis in subsets of rheumatoid arthritis defined by autoantibodies in three Asian populations from Malaysia. METHODS: 1,079 rheumatoid arthritis patients and 1,470 healthy controls were included in the study. Levels of antibodies to citrullinated proteins (ACPA and rheumatoid factors were assessed and the PCR-SSO method was used for HLA-DRB1 genotyping. RESULTS: The proportion of ACPA positivity among Malay, Chinese and Indian rheumatoid arthritis patients were 62.9%, 65.2% and 68.6%, respectively. An increased frequency of SE alleles was observed in ACPA-positive rheumatoid arthritis among the three Asian ethnic groups. HLA-DRB1*10 was highly associated with rheumatoid arthritis susceptibility in these Asian populations. HLA-DRB1*0405 was significantly associated with susceptibility to rheumatoid arthritis in Malays and Chinese, but not in Indians. HLA-DRB1*01 did not show any independent effect as a risk factor for rheumatoid arthritis in this study and HLA-DRB1*1202 was protective in Malays and Chinese. There was no association between SE alleles and ACPA- negative rheumatoid arthritis in any of the three Asian ethnic groups. CONCLUSION: The HLA-DRB1 SE alleles increase the risk of ACPA-positive rheumatoid arthritis in all three Asian populations from Malaysia.

Rheumatoid arthritis patients are at higher risk of developing comorbidities. The main objective of this study was to evaluate the prevalence of major comorbidities in Chinese rheumatoid arthritis patients. We also aimed to identify factors associated with these comorbidities. Baseline demographic, clinical characteristics and comorbidity data from RA patients enrolled in the Chinese Registry of rhEumatoiD arthrITis (CREDIT) from Nov 2016 to August 2017 were presented and compared with those from five other registries across the world. Possible factors related to three major comorbidities (cardiovascular disease, fragility fracture and malignancy) were identified using multivariate logistic regression analyses. A total of 13,210 RA patients were included (80.6% female, mean age 52.9 years and median RA duration 4.0 years). Baseline prevalence rates of major comorbidities were calculated: CVD, 2.2% (95% CI 2.0-2.5%); fragility fracture, 1.7% (95% CI 1.5-1.9%); malignancy, 0.6% (95% CI 0.5-0.7%); overall major comorbidities, 4.2% (95% CI 3.9-4.6%). Advanced age was associated with all comorbidities. Male gender and disease duration were positively related to CVD. Female sex and longer disease duration were potential risk factors for fragility fractures. Ever use of methotrexate (MTX) was negatively related to baseline comorbidities. Patients with rheumatoid arthritis in China have similar prevalence of comorbidities with other Asian countries. Advanced age and long disease duration are possible risk factors for comorbidities. On the contrary, MTX may protect RA patients from several major comorbidities, supporting its central role in the management of rheumatoid arthritis.

Full text: Polymyalgia rheumatica (PMR) and rheumatoid arthritis (RA) are clinical diagnoses that may be difficult to differentiate in the elderly RA can present with a polymyatgic onset, and the manifestations of PMR include peripheral synovitis. HLA DR4 alleles are over-represented in both diseases The APF is a serum antibody against profilaggrins which is detected by binding to cytoplasmic granules in buccal mucosal cells It is found in a high percentage (78%) Of both seropositive and seronegative rheumatoid arthritis patients. We studied the APF in 17 patients with PMR (by Hunder criteria). 13 age and sex matched patients with RA (by ACR criteria) and 10 healthy controls, to see whether the presence of APF could help distinguish PMR from RA. APF was assayed using a standard buccal mucosal cell-based immunofluorescence technique Rheumatoid factor was measured by latex agglutination and by ELISA. 11/13 (85%) Of the RA patients were APF positive, of which 6/11 (55%) were strongly positive. 13/17 (76%) Of the PMR patients were positive but none of these were strongly positive Of the controls 2/10 (20%) were positive. APF had a sensitivity of 87% and specificity of 67% for PMR and a sensitivity of 85% and specificity of 80% for RA. The combination of an APF and an RA latex test resulted in a sensitivity of 82% and specificity of 0% for RA patients. We conclude that the presence of APF does not distinguish RA from PMR. This study provides additional evidence that RA and PMR are related diseases

Ghrelin is a powerful, endogenous orexigenic peptide. In addition, ghrelin has anti-inflammatory effects, and it has been reported that ghrelin down-regulates pro-inflammatory cytokines, including interleukin (IL)-1beta and tumor necrosis factor (TNF)-alpha. Obestatin appears to decrease food intake and appetite, and its potential role in inflammation is not yet clear. The aims of this study were to assess total and acylated (active) ghrelin and obestatin serum levels and their relations with inflammatory status in rheumatoid arthritis (RA) patients. Fasting blood samples were obtained from 37 patients with RA, 29 patients with Behçet's disease (BD) and 28 healthy controls (HC). Total ghrelin and obestatin levels were measured by radioimmunoassay and acylated ghrelin was quantified by enzyme-linked immunosorbent assay. Patients with RA had lower total ghrelin, but higher obestatin levels than patients with BD (pghrelin. Total ghrelin level was not correlated with any study parameters in the all groups. Obestatin level correlated with erythrocyte sedimentation rate and DAS-28 in the RA group, the level of IL-6 in the BD group, and with the level of TNF-alpha in the HC group (r=0.400, pghrelin and clinical or laboratory markers of disease activity in RA. Surprisingly, obestatin correlated with some inflammatory markers. So, obestatin seems to be more valuable than ghrelin in the pathogenesis of RA.

To find out the factors that are associated with sustained remission measured by DAS28 and boolean ACR EULAR 2011 criteria at the time of diagnosis of rheumatoid arthritis. Medical records of patients with rheumatoid arthritis in sustained remission according to DAS28 were reviewed. They were compared with patients who did not achieved values of DAS28<2.6 in any visit during the first 3 years after diagnosis. We also evaluated if patients achieved the boolean ACR/EULAR criteria. Variables analyzed: sex, age, smoking, comorbidities, rheumatoid factor, anti-CCP, ESR, CRP, erosions, HAQ, DAS28, extra-articular manifestations, time to initiation of treatment, involvement of large joints, number of tender joints, number of swollen joints, pharmacological treatment. Forty five patients that achieved sustained remission were compared with 44 controls. The variables present at diagnosis that significantly were associated with remission by DAS28 were: lower values of DAS28, HAQ, ESR, NTJ, NSJ, negative CRP, absence of erosions, male sex and absence of involvement of large joints. Only 24.71% achieved the boolean criteria. The variables associated with sustained remission by these criteria were: lower values of DAS28, HAQ, ESR, number of tender joints and number of swollen joints, negative CRP and absence of erosions. The factors associated with sustained remission were the lower baseline disease activity, the low degree of functional disability and lower joint involvement. We consider it important to recognize these factors to optimize treatment. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

A 56-year-old woman, treated with tocilizumab (TCZ) for 8 months for severe rheumatoid arthritis (RA), was admitted to the hospital due to the swelling and tenderness of parotid glands. The patient was diagnosed with seropositive erosive RA in 1988, and treated with different disease modifying antirheumatic drugs (DMARDs) that were used together with a low dosage of glucocorticoides, followed by biologic therapy with infliximab and adalimumab which also proved to be inefficient. The patient had an excellent initial response on TCZ therapy. After 8 months, she was presented with an extreme enlargement of parotid glands. Bacterial, viral, and granulomatous diseases were excluded. A spectrum of autoantibodies including anti-Ro and anti-La showed normal values, expect for slightly elevated anti-cyclic citrullinated peptide (anti-CCP) and extreme elevation of the rheumatoid factor (RF) to 10,100 IU/ml. The biopsy of salivary glands was done and histological specimen showed limphoplasmocytic syaloadenitis. Tocilizumab therapy was stopped and the dosage of glucocorticoids and methotrexate (MTX) was raised. After 6 weeks, the patient was in better condition with slightly lower levels of RF (9,010 IU/ml). We hypothesise that in this patient, TCZ stimulated RF hyper production which can induce a paradoxical secondary syaloadenitis in RA.

Full Text Available Rheumatoid arthritis is the most common inflammatory joint disease with 1 percent prevalence in community which presents with symmetrical polyarthritis of hands with inflammatory behavior. Several studies in recent years were conducted for evaluation of inflammatory cytokines such as IL1-α (Interlukin 1α and TNF- α (Tumor necrosis factor in rheumatologic disorders including rheumatoid arthritis to find new treatment methods base to pathogenesis. In this study different serum levels of IL1-α and TNF- α in 160 rheumatoid arthritis patients with active and inactive disease and also disease with or without bone erosion are assessed. 4% of our patients had rheumatoid nodule and 70% of all patients had positive RF, IL1-α, and TNF- α levels. Active with bone erosion patients had IL1-α and TNF- α serum levels higher than active without bone erosion patients; it was not significant in T-test but it was significant in Mann-Whitney Test. The results was the same as expected; IL1-α, and TNF- α serum levels were higher in active with bone erosion in comparison with inactive without bone erosion patients.

The future role of anti-tumour necrosis factor (TNF) products in the treatment of rheumatoid arthritis.

Tumour necrosis factor-alpha (TNF alpha) is a pleiotropic cytokine which is overproduced in rheumatoid joints primarily by macrophages. This cytokine has a potential pathogenic role in the establishment of rheumatoid synovitis, in the formation of pannus tissue and in the process of joint destruction, as it increases synoviocyte proliferation and triggers a cascade of secondary mediators involved in the recruitment of inflammatory cells, in neo-angiogenesis and in the process of joint destruction. These findings made TNF alpha a potential target for anticytokine therapy. Experimental studies have shown that TNF alpha blockade by monoclonal antibodies or by soluble TNF receptor reduced the extent and severity of arthritis both in collagen-induced arthritis in mice and in transgenic mice overexpressing TNF alpha, which develop a rheumatoid-like destructive arthritis. Clinical studies based on the use of anti-TNF alpha antibodies or soluble receptors have suggested a potential beneficial effect of TNF alpha-blocking therapy in inducing amelioration of inflammatory parameters in patients with long-standing active disease. In these patients anti-TNF alpha therapy induces a rapid improvement in multiple clinical assessment of disease activity, including morning stiffness, pain score, Ritchie articular index and swollen joint count. The clinical benefits are associated with an improvement in some serological parameters, such as C-reactive protein and serum amyloid-A, erythrocyte sedimentation rate, blood cytokine levels, haemoglobin, white cells and platelet counts, rheumatoid factor titre and histological features of the synovium. However, it remains to be determined whether anti-TNF alpha therapy may be useful in the long term management of rheumatoid patients and in the achievement of better outcomes of disease. Because TNF alpha production also serves a specific function in host defence against infections and tumours, the adverse effects of long term anti-TNF alpha

Full Text Available In order to study the humoral immune response against Epstein-Barr virus (EBV in patients with rheumatoid arthritis (RA and to compare it with the two major autoantibody types in RA, plasma samples from 77 RA patients, 28 patients with systemic lupus erythematosus (SLE, and 28 healthy controls (HCs were investigated by enzyme-linked immunosorbent assays (ELISA. Increased percentages of positives and concentrations of IgG/IgA/IgM antibodies against the latent EBV nuclear antigen-1 (EBNA-1 were observed in RA patients compared to SLE patients and HCs. Increased concentrations and percentages of positives of IgG/IgA/IgM against the early lytic EBV antigen diffuse (EAD were also found in RA patients compared to HCs but were highest in SLE patients. Furthermore, associations between the elevated EBNA-1 IgA and EBNA-1 IgM levels and the presence of IgM and IgA rheumatoid factors (RFs and anti-citrullinated protein antibodies (ACPAs, IgG and between elevated IgA concentrations against EAD and the presence of RFs and ACPAs in RA patients were found. Thus, RA patients had elevated antibodies of all isotypes characteristic of latent EBV infection (whereas SLE patients had elevated antibodies characteristic of lytic EBV infection. Notably, for IgM and IgA (but not IgG, these were associated with the presence of characteristic RA autoantibodies.

Rheumatoid arthritis (RA) and chronic periodontitis are the most common chronic inflammatory diseases with significant pathological and clinical similarities. Numerous studies have indicated a relationship between rheumatoid arthritis and periodontal disease. The aim of this study was to compare the TNF-α levels in saliva among patients with Rheumatoid arthritis (RA) and chronic periodontitis as well as healthy subjects. One hundred and seventy-one patients were enrolled in this cross-sectional study. Fifty-seven patients diagnosed of RA, 57 patients with chronic periodontitis and 57 healthy subjects. These patients have been examined with regard to TNF-α level from salivary samples. Their teeth were examined with regard to Plaque Index , Gingival Index, probing depth and clinical attachment level.All patients were non-smokers. The results revealed a significant difference in all periodontal parameters among the three groups. The chronic periodontitis group showed a significantly higher value in all clinical periodontal parameters in comparison to both the RA and healthy groups. No significant difference was found between salivary TNF-α level among the three study groups. Patients with chronic periodontitis had the highest periodontal indices. However there was no significant difference regarding the level of salivary TNF-α. Hence, suppression of proinflammatory cytokines might prove beneficial in suppressing periodontal diseases among RA patients.

Although both rheumatoid factor (RF) and anticyclic citrullinated peptide antibodies (anti-CCP) are useful for diagnosing rheumatoid arthritis (RA), the impact of these autoantibodies on the efficacy of tumor necrosis factor (TNF) inhibitors has been controversial. The aim of this post hoc analysis of a randomized double-blind study (the RISING study) was to investigate the influences of RF and anti-CCP on the clinical response to infliximab in patients with RA. Methotrexate-refractory patients with RA received 3 mg/kg of infliximab from weeks 0 to 6 and then 3, 6, or 10 mg/kg every 8 weeks from weeks 14 to 46. In this post hoc analysis, patients were stratified into three classes on the basis of baseline RF/anti-CCP titers: "low/low-C" (RF < 55 IU/ml, anti-CCP < 42 U/ml), "high/high-C" (RF ≥ 160 IU/ml, anti-CCP ≥ 100 U/ml), and "middle-C" (neither low/low-C nor high/high-C). Baseline plasma TNF level, serum infliximab level, and disease activity were compared between the three classes. Baseline RF and anti-CCP titers showed significant correlations with baseline TNF and infliximab levels in weeks 2-14. Comparison of the three classes showed that baseline TNF level was lowest in the low/low-C group and highest in the high/high-C group (median 0.73 versus 1.15 pg/ml), that infliximab levels at week 14 were highest in the low/low-C group and lowest in the high/high-C group (median 1.0 versus 0.1 μg/ml), and that Disease Activity Score in 28 joints based on C-reactive protein at week 14 was lowest in the low/low-C group and highest in the high/high-C group (median 3.17 versus 3.82). A similar correlation was observed at week 54 in the 3 mg/kg dosing group, but not in the 6 or 10 mg/kg group. Significant decreases in both RF and anti-CCP were observed during infliximab treatment. RF/anti-CCP titers correlated with TNF level. This might explain the association of RF/anti-CCP with infliximab level and clinical response in patients with RA

Suggested predictors of rheumatoid arthritis (RA) include environmental exposure, such as smoking. Our purpose was to investigate potential predictors of RA in a nested case-control study based on a prospective cohort. Between 1991 and 1996, 30,447 persons were included in the Malmö Diet and Cancer Study (MDCS). Individuals who developed RA after inclusion up to 31 December 2004 were identified by linking the database to different registers. Four controls were selected for every case. Data on lifestyle factors were collected in the MDCS. We identified 172 incident cases of RA [36 men/136 women, mean age at diagnosis 63 years, 69% rheumatoid factor (RF) positive, median time from inclusion to diagnosis 5 (range 1-13) years]. In bivariate analyses, baseline smoking [odds ratio (OR) 2.02, 95% confidence interval (CI) 1.31-3.12] and a low level of formal education (i.e. ≤ 8 years; OR 2.42, 95% CI 1.18-4.93 vs. University degree) predicted subsequent development of RA. Infrequent baseline alcohol consumption was a predictor of RA (OR 3.47, 95% CI 1.91-6.30) compared to recent use (within the past month), and individuals with moderate baseline alcohol consumption (3.5-15.2 g/day vs. education. Smoking and a low level of formal education were found to be independent predictors of RA. Moderate alcohol consumption may also be associated with a reduced risk.

Michal Ziarko

2014-01-01

Full Text Available Aim. Rheumatoid arthritis is one of the most severe chronic diseases. In many cases it leads to disability and results in a decreased quality of life and increased levels of anxiety and depression. The problem that needs to be addressed is the following: which mental processes lead to increased levels of depression in patients with rheumatoid arthritis? Methods. 210 patients with rheumatoid arthritis hospitalized in rheumatology wards took part in the research. They filled in illness perception questionnaires (IPQ-R and questionnaires for testing strategies of handling stress (Mini-COPE and the level of depression (CES-D. Results. The observed correlation coefficients indicate that several elements of the perception of one’s disease moderately contribute to a high level of depression. Moreover, frequent use of dysfunctional coping strategies contributed to high levels of depression. Dysfunctional coping was moderately linked to depression. Conclusion. The conducted analyses confirmed the links between the beliefs about the disease and levels of depression and showed that the use of dysfunctional coping strategies mediates the relationship between the following elements of the representation of the disease: illness coherence, emotional representation, psychological attribution, risk factors, and the level of depression.

Rheumatoid arthritis (RA) is a chronic disease with many somatic, psychological and social consequences. Somatic consequences are connected mainly with increasing levels of negative emotions such as depression, anxiety and a tendency to react with anger to many daily life situations. Additionally, loss of hope has been reported as another effect of rheumatoid arthritis. The goal of the study was to describe anxiety levels and its determinants in RA patients. The study was carried out on 31 RA patients, 22 (71%) of whom were females and 9 (29%) of whom were males. The respondents were assessed with a set of questionnaires such as Spielberger's State-Trait Anxiety Inventory (STAI), Multidimensional Health Locus of Control Scale (MHLC), The Coping Inventory for Stressful Situations (CISS) and Eysenck's Personality Questionnaire - Revised (EPQ-R). We have found the relationship between anxiety as (1) a state and external locus of control - powerful others (tau-b = 0.23, p = 0.09), task - oriented style of coping (tau-b = -0.34, p = 0.01), emotion-oriented style of coping (tau-b = 0.33, p = 0.02) and neuroticism levels (tau-b = 0.29, p = 0.03) and (2) anxiety as a trait and external locus of control - powerful others (tau-b = 0.40, p = 0.01), task - oriented style of coping (tau-b = 0.36, p = 0.01), emotion-oriented style of coping (tau-b = 0.33, p = 0.02) and neuroticism levels (tau-b = 0.47, p = 0,01).

Rheumatoid cachexia revisited: a metabolic co-morbidity in rheumatoid arthritis

Full Text Available Rheumatoid arthritis (RA is a chronic inflammatory disease in which pro-inflammatory cytokines, including tumor necrosis factor (TNF-alpha, play a crucial role. The chronic inflammation, combined with reduced physical activity, leads to muscle wasting whereas fat mass would be maintained; the resulting abnormal metabolic state is described as rheumatoid cachexia. Since the loss of muscle volume would be compensated by the increased fat mass, body mass index (BMI is reported not to reflect the nutritional status in RA patients. The implication of rheumatoid cachexia for cardiovascular risk and clinical prognosis is not clearly understood, however, adequate control of disease activity in combination with appropriate physical exercise could be the most important strategy to control rheumatoid cachexia and related metabolic problems.

Keane, A; Woods, R; Dowding, V; Roden, D; Barry, C

1987-10-01

Anticardiolipin antibody (ACA) was present in the sera of 49% of 90 consecutive patients with rheumatoid arthritis (RA). The ACA was absent in 30 control patients with osteoarthritis. C-reactive protein levels equal to or exceeding 7 mg/dl were found in 10 patients all of whom were ACA positive. ACA was present in a larger proportion of rheumatoid factor (RF) positive than of RF negative patients. Male sex and extra-articular manifestations of RA were both more common in ACA positive than ACA negative patients. In the ACA positive group the lupus anticoagulant and VDRL tests were negative. However, a small number of patients had evidence of vascular events.

Objective Alterations in the microbiome, including the periodontal microbiome, may be a risk factor for rheumatoid arthritis (RA). Most studies that have analyzed this association are relatively small, focus primarily on a single periodontal pathogen (Porphyromonas gingivalis), and are not population-based. We investigated the association between elevated serum IgG antibodies to 19 periodontal species and the prevalence of rheumatoid factor (RF) in a large nationally representative sample of adults. Methods The Third National Health and Nutrition Examination Survey is a cross-sectional sample of the non-institutionalized US population (n=33,994). Our study population included all dentate participants ≥60 years, who did not have RA as defined by a modified version of the American College of Rheumatology 1987 criteria, and had complete data for both serum IgG antibodies against periodontal bacteria and serum RF antibody titer (n=2461). Results Adjusted odds ratios (ORs) (95% CI) summarizing the relationship between the 19 periodontal serum IgGs and RF seropositivity ranged from 0.53 (0.29, 0.97) to 1.27 (0.79, 2.06), and 17 of the 19 observed ORs were periodontal IgGs to be mostly unassociated with RF seropositivity in the nationally representative NHANES III. Elevated antibody levels to P. intermedia and C. ochracea were associated with lower odds of RF seropositivity. PMID:27110949

Rheumatoid factors (RFs) are endogenous human antibodies that bind to human gamma globulins. RFs demonstrate preferential binding to aggregated gamma globulins and are involved in the clearing mechanism of immune complexes. Immunoassays designed to measure human anti-human antibodies (HAHA) after administration of monoclonal antibody therapeutics are thus vulnerable to interference from RFs. When using a sensitive electrochemiluminescent (ECL) bridging immunoassay, samples from subjects with rheumatoid arthritis demonstrated much higher baseline reactivity than healthy subjects. Interference was found to be dependent on the aggregation state of the therapeutic antibody that had been conjugated with the detection reagent (ruthenium). Size exclusion high performance liquid chromatography (SE-HPLC) demonstrated that of the total integrated peaks, as little as 0.55% high molecular weight aggregates (>600kDa) were sufficient to cause increased reactivity. Stability studies of the ruthenium and biotin conjugated therapeutic antibody indicated that storage time, temperature and buffer formulation were critical in maintaining the integrity of the reagents. Through careful SE-HPLC monitoring we were able to choose appropriate storage and buffer conditions which led to a reduction in the false reactivity rate in therapeutic-naïve serum from a rheumatoid arthritis population.

Studies have suggested that abnormal expression of complement regulatory proteins and cytokines contribute significantly to the path-physiology of rheumatoid arthritis. In this context, Decay accelerating factor (DAF) a complement regulatory protein is gaining increased attention. With the notion that immune effecter mechanisms are all interlinked and circulating peripheral blood mononuclear cells (PBMCs) should have a role in a systemic disease like rheumatoid arthritis, we studied the modulation and significance of PBMC-DAF and cytokines in RA. Seventy-five RA patients and 75 healthy controls were recruited. Expression of DAF and cytokines (IFN-γ, IL-17A and IL-10) in the PBMCs of patients and controls was determined. Correlations among DAF, cytokines, and disease activity were evaluated by standard statistical methods. The effect of IFN-γ, IL-17A, and IL-10 on the expression of DAF in patients and controls was studied in vitro. Expression of PBMC-DAF declined in patients both at mRNA and surface level and correlated negatively with the disease activity. Expression of IFN-γ also declined in patients but correlated positively with DAF and negatively with disease activity. Expression of IL-17A and IL-10 was higher in patients. The levels correlated positively with disease activity and negatively with DAF both in patients and controls. In vitro studies indicated that IFN-γ up-regulated DAF expression in PBMCs, whereas IL-17A and IL-10 had negative effect on the same. The decline in the PBMC-DAF is a contributing factor in manifestations of RA. Cytokine environment contributes to this decline. These findings brought novel insights into the complement-cytokine axis in the path-physiology of RA.

The aim of the present study was to investigate in vivo in a mouse model the stimulation of neoangiogenesis by synovial fluids of patients with rheumatoid arthritis (RA) and to determine the role of tumor necrosis factor (TNF)-alpha and platelet-activating factor (PAF) in the formation of new vessels. Angiogenesis was studied in a mouse model in which Matrigel, injected subcutaneously, was used as a vehicle for the delivery of potential angiogenic stimuli. Synovial fluids of patients with RA but not with osteoarthritis (OA) were shown to induce neoangiogenesis. Since synovial fluid of patients with RA contained significantly higher levels of TNF-alpha-like bioactivity and of PAF than that of patients with OA, the role of these mediators was evaluated by using an anti-TNF-alpha neutralizing monoclonal antibody (mAb) and a PAF receptor antagonist, WEB 2170. When added to Matrigel, anti-TNF-alpha mAb and particularly WEB 2170 significantly reduced neoangiogenesis induced by synovial fluids of RA patients. Moreover, PAF extracted and purified from synovial fluid induced angiogenesis. These results suggest that the neoangiogenesis observed in rheumatoid synovitis may be due, at least in part, to the angiogenic effect of locally produced TNF-alpha and PAF.

Objective; To investigate the clinical usefulness of combined determination of serum rheumatic factor (RF), anti-keratin antibody (AKA) and anti-cyclic citrullinated peptide antibody (anti-CCP antibody) levels for early diagnosis in patients with rheumatoid arthritis (RA). Methods: Serum RF ( with rate-nephelometry), AKA (with indirect immuno-fluorescence) and anti-CCP antibody (with ELISA) levels were determined in 40 patients with RA, 30 patients with SLE and 30 controls. Results: For diagnosis of RA; the sensitivity and specificity of RF was 70.0% and 90.0% respectively, the sensitivity and specificity of AKA was 35.0% and 96.7%, the sensitivity and specificity of anti-CCP-antibody was 85% and 93.3% respectively. With combined determination of RF, AKA and anti-CCP antibody, the sensitivity and specificity would be the highest, being 97.07 and 99.8% respectively. Conclusion: RF, AKA and anti-CCP antibody were useful diagnostic serum markers for rheumatoid arthritis and combined determination of these markers would be very useful for early diagnosis.

In the past decade significant advantages have been made in the treatment of rheumatoid arthritis (RA) and therapeutic strategies have changed a lot. These days, highly effective disease modifying anti-rheumatic drugs enable intervention early in the disease process, in order to prevent major joint damage. For years, serological support in the diagnosis of RA has been limited to the presence of rheumatoid factors, although not very specific for RA. During the last years a variety of circulating non-RF antibodies have been discovered and reported to be of potential diagnostic value. CCP2 proved to be a very disease-specific and even sensitive marker for RA. In addition to the diagnostic properties, CCP showed to be a good prognostic marker, CCP helps to predict the erosive or nonerosive progression of the disease, and CCP is already present early in the disease. This diagnostic tool enables the clinician to choose the optimal therapeutic management for each single RA patient.

The presence of anticitrullinated protein antibodies (ACPA) in rheumatoid arthritis (RA) indicates a breach in immune tolerance. Recent studies indicate that this breach extends to homocitrullination of lysines with the formation of anti-carbamylated protein (anti-CarP) antibodies. We analyzed the clinical and serologic relationships of anti-CarP in 2 RA cohorts. Circulating levels of immunoglobulin G anti-CarP antibodies were determined by ELISA in established (Dartmouth-Hitchcock Medical Center) and early (Sherbrooke University Hospital Center) cohorts and evaluated for anticyclic citrullinated peptide antibodies (anti-CCP), specific ACPA, and rheumatoid factor (RF) levels using the Student t test and correlation analysis. We identified elevated anti-CarP antibodies titers in 47.0% of seropositive patients (Dartmouth, n = 164), with relationships to anti-CCP (p < 0.0001) and IgM-RF (p = 0.001). Similarly, 38.2% of seropositive patients from the Sherbrooke cohort (n = 171) had elevated anti-CarP antibodies; titers correlated to anti-CCP (p = 0.01) but not IgM-RF (p = 0.09). A strong correlation with anti-Sa was observed: 47.9% anti-Sa+ patients were anti-CarP antibodies+ versus only 25.4% anti-Sa- in the Sherbrooke cohort (p = 0.0002), and 62.6% anti-Sa+ patients versus 26.9% anti-Sa- were anti-CarP antibodies+ in Dartmouth (p < 0.0001). We found a more variable response for reactivity to citrullinated fibrinogen or to citrullinated peptides from fibrinogen and α enolase. In 2 North American RA cohorts, we observed a high prevalence of anti-CarP antibody positivity. We also describe a surprising and unexpected association of anti-CarP with anti-Sa antibodies that could not be explained by cross-reactivity. Further, considerable heterogeneity exists between anti-CarP reactivity and other citrullinated peptide reactivity, raising the question of how the pathogenesis of antibody responses for carbamylated proteins and citrullinated proteins may be linked in vivo.

To assess the 5-year progression of erosions and joint space narrowing (JSN) and their associations with rheumatoid factor (RF) status in 2 large, multicenter, early rheumatoid arthritis cohorts, spanning 25 years. Radiographic joint damage was recorded using the Sharp/van der Heijde (SHS) method in the Early Rheumatoid Arthritis Study (ERAS), 1986-2001, and the Early Rheumatoid Arthritis Network (ERAN), 2002-2013. Mixed-effects negative binomial regression estimated changes in radiographic damage over 5 years, including erosions and JSN, separately. RF, along with age, sex, and baseline markers of disease activity were controlled for. A total of 1,216 patients from ERAS and 446 from ERAN had radiographic data. Compared to ERAS, ERAN patients had a lower mean total SHS score at baseline (ERAN 6.2 versus ERAS 10.5; P < 0.001) and mean annual rate of change (ERAN 2.5 per year versus ERAS 6.9 per year; P < 0.001). Seventy-four percent of ERAS and 27% of ERAN patients progressed ≥5 units. Lower scores at baseline in ERAN were largely driven by reductions in JSN (ERAS 3.9 versus ERAN 1.2; P < 0.001), along with erosions (ERAS 1.9 versus ERAN 0.8; P < 0.001). RF was associated with greater progression in each cohort, but the absolute difference in mean annual rate of change for RF-positive patients was substantially higher for ERAS (RF positive 8.6 versus RF negative 5.1; P < 0.001), relative to ERAN (RF positive 2.0 versus RF negative 1.9; P = 0.855). Radiographic progression was shown to be significantly reduced between the 2 cohorts, and was associated with lower baseline damage and other factors, including changes in early disease-modifying antirheumatic drug use. The impact of RF status as a prognostic marker of clinically meaningful change in radiographic progression has markedly diminished in the context of more modern treatment. © 2017, American College of Rheumatology.

Rafael Kmiliauskis Santos Gomes

Full Text Available Abstract Objective: To estimate the prevalence of ischemic heart disease and associated factors in patients with rheumatoid arthritis. Methods: A cross-sectional study using the American College of Rheumatology diagnostic criteria in order to select patients seen at primary or secondary health care units in Blumenau, Santa Catarina, Southern Brazil, in 2014. The presence of ischemic heart disease was defined as an acute myocardial infarction with percutaneous coronary intervention or coronary artery bypass graft surgery that has occurred after diagnosis. Fischer's exact test, Wald's linear trend test, and multivariate logistic regression analysis were used to test the associations. Results: Among 296 patients (83.1% female with a mean age of 56.6 years and a mean rheumatoid arthritis duration of 11.3 years, 13 reported having acute myocardial infarction requiring a percutaneous or surgical reperfusion procedure, a prevalence of 4.4% (95% CI 2.0-6.7. Diabetes Mellitus (odds ratio [OR] 4.9 [95% CI 1.6-13.8] and disease duration >10 years (OR 8.2 [95% CI 1.8-39.7] were the only factors associated with an ischemic disease that remained in the final model, after the multivariate analysis. Conclusion: The prevalence of acute myocardial infarction was similar to that observed in other studies. Among the traditional risk factors, Diabetes Mellitus, and among the factors related to rheumatoid arthritis, disease duration, were the variables associated with comorbidity.

Infrared (IR)-A irradiation can be useful in back and musculoskeletal pain therapy. In this study joint and vertebral column pain and mobility were measured during two weeks of IR-A irradiation treatment of patients suffering from degenerative osteoarthritis of hip and knee, low back pain, or rheumatoid arthritis. Additionally, before and after IR-A treatment MDA serum levels were measured to check if MDA variations accompany changes in pain intensity and mobility. Two-hundred and seven patients were divided into verum groups getting IR-irradiation, placebo groups getting visible, but not IR irradiation, and groups getting no irradiation. In osteoarthritis significant pain reduction according to Visual Analogue Scale and mobility improvements occurred in the verum group. Even though beneficial mean value changes occurred in the placebo group, the improvements in the placebo and No Irradiation groups were without statistical significance. In low back pain, pain and mobility improvements (by 35 - 40 %) in the verum group were found, too. A delayed (2 nd week) mobility improvement in rheumatoid arthritis was seen. However, pain relief was seen immediately. In patients suffering from low back pain or rheumatoid arthritis, the pain and mobility improvements were accompanied by significant changes of MDA serum levels. However, MDA appears not a sensitive bio factor for changes of the pain intensity in degenerative osteoarthritis. Nevertheless, unaffected or lowered MDA levels during intensive IR-A therapy argue against previous reports on free radical formation upon infrared. In conclusion, rapid beneficial effects of IR-A towards musculoskeletal pain and joint mobility loss were demonstrated. (authors)

Porphyromonas gingivalis has been implicated as an etiologic agent of rheumatoid arthritis (RA) because of the expression of peptidylarginine deiminase. The present study evaluates whether periodontal treatment may affect serum antibodies to P. gingivalis and citrulline levels in relation to disease activity of RA. Fifty-five patients with RA were randomly assigned to receive oral hygiene instruction and supragingival scaling (treatment group, n = 26) or no periodontal treatment (control group, n = 29). Periodontal and rheumatologic parameters and serum levels of cytokine and inflammatory markers citrulline and immunoglobulin (Ig)G to P. gingivalis were examined at baseline and 8 weeks later. Both groups did not differ statistically in any parameters except percentage of sites with probing depth and clinical attachment level ≥ 4 mm at baseline. The treatment group exhibited a significantly greater decrease in disease activity score including 28 joints using C-reactive protein (DAS28-CRP) (P = 0.02), serum levels of IgG to P. gingivalis hemin binding protein (HBP)35 (P = 0.04), and citrulline (P = 0.02) than the control group. Serum levels of IgG to P. gingivalis HBP35 were significantly correlated positively with those of anti-cyclic citrullinated peptide antibodies (P = 0.0002). The same correlation was obtained between serum levels of IgG to P. gingivalis-sonicated extracts and those of rheumatoid factor (P = 0.02). These results suggest that supragingival scaling decreases DAS28-CRP and serum levels of IgG to P. gingivalis HBP35 and citrulline in patients with RA. These observations may reflect a role of P. gingivalis in the protein citrullination, which is related to the pathogenesis of RA.

Aims This study aimed to compare the clinical outcomes of rotator cuff repair in patients with rheumatoid arthritis with those of patients who have no known history of the disease. We hypothesised that the functional outcomes are comparable between patients and without rheumatoid arthritis and may be affected by the level of disease activity, as assessed from C-reactive protein (CRP) level and history of systemic steroid intake. Patients and methods We conducted a retrospective review of the institutional surgical database from May 1995 to April 2012. Twenty-nine patients with rheumatoid arthritis who had rotator cuff repair were enrolled as the study group. Age, sex, and tear size matched patients with no disease who were selected as the control group. The mean duration of follow-up was 46 months (range 24-92 months). Clinical outcomes were assessed with the American Shoulder and Elbow Surgeons (ASES) questionnaire, Constant score and visual analogue scale (VAS). All data were recorded preoperatively and at regular postoperative follow-up visits. CRP was measured preoperatively as the disease activity marker for rheumatoid arthritis. Medication history was thoroughly reviewed in the study group. Results In patients with rheumatoid arthritis, all shoulder functional scores improved after surgery (ASES 56.1-78.1, Constant 50.8-70.5 and VAS 5.2-2.5; P rheumatoid arthritis was comparable to that of the control group (difference with control: ASES 78.1 vs. 85.5, P = 0.093; Constant 70.5 vs. 75.9, P = 0.366; VAS 2.5 vs. 1.8, P = 0.108). Patients with rheumatoid arthritis who had an elevated CRP level (> 1 mg/dl) showed inferior clinical outcomes than those with normal CRP levels. Patients with a history of systemic steroid intake showed inferior functional outcomes than those who had not taken steroids. Conclusions Surgical intervention for rotator cuff tear in patients with rheumatoid arthritis improved the shoulder functional outcome comparable to that in

Objective was to describe the radiographic cervical spine changes in rheumatoid arthritis patients.Forty-nine patients (37 females and 12 males ) diagnosed with rheumatoid arthritis at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia between June 1998 and December 2000, were studied for their radiographic cervical spine changes . Their mean age at disease onset was 41.4 + 13.4 years (range of 18-73)and mean duration of disease was 9.1+-6.28 years (range of 2-34). Their demographic data including rheumatoid factor status was obtained. Standard conventional radiographs cervical spine were obtained to study the cervical spine changes. Cervical radiographic changes were found in 34 patients (27 females and 7 males) 10 had subluxation (7 with atlanto-axial subluxation,2 with sub-axial subluxation,and one with lateral subluxation ). No vertical impaction was seen. Erosion of odontoid process was seen in one patient .All were rheumatoid seropositive Cervical spine changes in patients with rheumatoid arthritis are common, in particular subluxation in the upper cervical spine. Our study showed somewhat lesser prevalence of these changes. These were clinically correlated with disease duration, female sex, and rheumatoid factor, but were not clinically significant. (author)

The aim of the present study was to evaluate the possible association between the Q223R Leptin receptor (LEPR) polymorphism (A>G; rs1137101) and leptin levels in patients with rheumatoid arthritis (RA) from Western Mexico. A cross-sectional study was performed with 70 RA patients and 74 controls subject (CS). Disease activity was evaluated using DAS28 score, the Q223R LEPR polymorphism was determined by the Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) and serum leptin levels, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and rheumatoid factor (RF) were quantified. RA patients had significant high serum leptin levels compared with CS; leptin levels correlated strongly with body composition measures, but not with inflammatory markers, disease evolution, and activity. The genotype and allele frequencies of the Q223R LEPR polymorphism were not associated with RA. Similarly, leptin levels did not differ between Q223R LEPR genotypes. The LEPR Q223R polymorphism was not associated with RA risk in patients from Mexican population, even though high levels of serum leptin were present and these could explain the low weight observed in RA patients when they were compared to control subjects. However, the serum leptin levels did not correlate with inflammatory markers, severity and disease evolution.

A 30-year-old female patient with coexisting ankylosing spondylitis and rheumatoid arthritis was diagnosed and treated. The human leukocyte antigen (HLA)-B27 is a predisposing factor of ankylosing spondylitis and HLA-DR4 is a predisposing factor of rheumatoid arthritis. This patient was HLA-B27 and HLA-DR4 positive, and ankylosing spondylitis manifested before rheumatoid arthritis. After disease modifying anti-rheumatic drugs successfully arrested ankylosing spondylitis activity the patient conceived and delivered a healthy baby. One year later, she developed peripheral polyarthritis and was diagnosed with rheumatoid arthritis. We hypothesized that pregnancy may be one of the environmental factors that can activate rheumatoid arthritis, and that disease modifying anti-rheumatic drugs play an important role in keeping the disease under control.

Serum hyaluronan levels are increased in dialysis patients. We evaluated several factors that influence serum hyaluronan levels in 184 patients on chronic hemodialysis (duration 2.3 +/- 2.3 [SD] years). The levels were higher than normal in the whole group and in a subgroup of 133 patients without chronic infection, liver disease, or rheumatoid arthritis (215 +/- 19 and 205 +/- 22 microg/L, respectively). There was a tendency for the levels to be higher in a subgroup of patients with hepatitis c virus (HCV) infection. There was no correlation between hyaluronan levels, alanine aminotransferase (ALT), and duration or dose of dialysis. A weak but highly significant negative correlation between serum albumin levels and serum hyaluronan and ferritin levels was seen. The data suggest that chronic inflammation may explain, at least in part, the increased hyaluronan levels found in chronic dialysis patients.

CD8+ T Cells Specific to Apoptosis-Associated Antigens Predict the Response to Tumor Necrosis Factor Inhibitor Therapy in Rheumatoid Arthritis.

Full Text Available CD8+ T cells specific to caspase-cleaved antigens derived from apoptotic T cells (apoptotic epitopes represent a principal player in chronic immune activation, which is known to amplify immunopathology in various inflammatory diseases. The purpose of the present study was to investigate the relationship involving these autoreactive T cells, the rheumatoid arthritis immunopathology, and the response to tumor necrosis factor-α inhibitor therapy. The frequency of autoreactive CD8+ T cells specific to various apoptotic epitopes, as detected by both enzyme-linked immunospot assay and dextramers of major histocompatibility complex class I molecules complexed with relevant apoptotic epitopes, was longitudinally analyzed in the peripheral blood of rheumatoid arthritis patients who were submitted to etanercept treatment (or other tumor necrosis factor inhibitors as a control. The percentage of apoptotic epitope-specific CD8+ T cells was significantly higher in rheumatoid arthritis patients than in healthy donors, and correlated with the disease activity. More important, it was significantly more elevated in responders to tumor necrosis factor-α inhibitor therapy than in non-responders before the start of therapy; it significantly dropped only in the former following therapy. These data indicate that apoptotic epitope-specific CD8+ T cells may be involved in rheumatoid arthritis immunopathology through the production of inflammatory cytokines and that they may potentially represent a predictive biomarker of response to tumor necrosis factor-α inhibitor therapy to validate in a larger cohort of patients.

Alterations in the microbiome, including the periodontal microbiome, may be a risk factor for rheumatoid arthritis (RA). Most studies that have analyzed this association are relatively small, focus primarily on a single periodontal pathogen (Porphyromonas gingivalis), and are not population based. This study was undertaken to investigate the association between elevated serum levels of IgG antibodies to 19 periodontal species and the prevalence of rheumatoid factor (RF) in a large nationally representative sample of adults. The Third National Health and Nutrition Examination Survey (NHANES-III) is a cross-sectional sample of the noninstitutionalized US population (n = 33,994). Our study population included all dentate participants who were 60 years and older, did not have RA as defined by a modified version of the American College of Rheumatology 1987 criteria, and had complete data for both serum IgG antibodies against periodontal bacteria and serum RF antibody titer (n = 2,461). Adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) summarizing the relationship between the 19 periodontal serum IgG antibodies and RF seropositivity ranged from 0.53 (95% CI 0.29-0.97) to 1.27 (95% CI 0.79-2.06), and 17 of the 19 observed ORs were periodontal bacteria are mostly unassociated with RF seropositivity in the nationally representative NHANES-III. Elevated levels of antibodies to P intermedia and C ochracea are associated with lower odds of RF seropositivity. © 2016, American College of Rheumatology.

We investigated SIRT-1 genetic variant and its association with vitamin D level in Egyptian patients with rheumatoid arthritis (RA). Seventy Egyptian subjects were enrolled in our study and divided into two groups: RA group (n = 50 patients) and healthy control group (n = 20 subjects). Five milliliter blood sample was withdrawn from each subject followed by laboratory investigation and DNA extraction for SIRT-1 gene polymorphism assessment (rs7895833 A>G, rs7069102 C>G and rs2273773 C>T) and vitamin D level expression. There was statistically significant difference between rheumatoid cases and controls with regard to vitamin D level with 88% of cases showing insufficient vitamin D versus all controls showing sufficient level. SIRT-1 different SNPs rs2273773, rs7895833and rs7069102 genotype frequencies were statistically significant in RA compared to control group (P = 0.001). There was no statistically significant difference between different genotypes of rs2273773, rs7895833 and rs7069102 with regard to vitamin D level. We concluded that there is a strong association between SIRT-1 polymorphism genotyping and RA. Vitamin D level was insufficient in Egyptian patients with RA.

Full Text Available In order to investigate the predictive factors related to clinical efficacy and radiographic progression at 24 weeks by looking at the serum levels of tumor necrosis factor (TNF-α and interleukin (IL-6 including baseline characteristics in patients with rheumatoid arthritis (RA treated with golimumab, serum concentrations of TNF-α and IL-6 were analyzed every 4 weeks up to 24 weeks in 47 patients treated with golimumab. Baseline levels of the Disease Activity Score 28 C-reactive protein (DAS28-CRP and Simplified Disease Activity Index (SDAI scores were also assessed. Radiographic progression using the van der Heijde-modified Sharp (vdH-S score was assessed in 29 patients. Multiple regression analyses related to the DAS28-CRP score and delta total sharp score at 24 weeks was undertaken using the baseline characteristics of patients and serum concentrations of matrix metalloproteinase (MMP-3, TNF-α, and IL–6. The DAS28-CRP score and SDAI decreased significantly at 4 weeks up to 24 weeks compared with baseline. Serum levels of TNF-α were not changed significantly up to 24 weeks compared with baseline, but those of IL-6 decreased significantly at 4 weeks up to 8 weeks. Multiple regression analyses showed that disease duration and serum levels of MMP-3 were related significantly to the DAS28-CRP score at 24 weeks. Radiographic progression was related significantly to disease duration with regard to joint space narrowing and bone erosion. However, serum levels of TNF-α and IL-6 were not correlated significantly with the DAS28-CRP score and radiographic progression. These data suggest that decreasing serum levels of IL-6 significantly, MMP-3, and disease duration are predictive factors for RA activity in patients taking golimumab.

Fears and beliefs in rheumatoid arthritis and spondyloarthritis: a qualitative study.

Directory of Open Access Journals (Sweden)

Francis Berenbaum

Full Text Available To explore beliefs and apprehensions about disease and its treatment in patients with rheumatoid arthritis and spondyloarthritis.25 patients with rheumatoid arthritis and 25 with spondyloarthritis participated in semi-structured interviews about their disease and its treatment. The interviews were performed by trained interviewers in participants' homes. The interviews were recorded and the main themes identified by content analysis.Patients differentiated between the underlying cause of the disease, which was most frequently identified as a hereditary or individual predisposition. In patients with rheumatoid arthritis, the most frequently cited triggering factor for disease onset was a psychological factor or life-event, whereas patients with spondyloarthritis tended to focus more on an intrinsic vulnerability to disease. Stress and overexertion were considered important triggering factors for exacerbations, and relaxation techniques were frequently cited strategies to manage exacerbations. The unpredictability of the disease course was a common source of anxiety. Beliefs about the disease and apprehensions about the future tended to evolve over the course of the disease, as did treatment expectations.Patients with rheumatoid arthritis and spondyloarthritis hold a core set of beliefs and apprehensions that reflect their level of information about their disease and are not necessarily appropriate. The physician can initiate discussion of these beliefs in order to dispel misconceptions, align treatment expectations, provide reassurance to the patient and readjust disease management. Such a dialogue would help improve standards of care in these chronic and incapacitating diseases.

Rheumatoid arthritis is thought to induce conductive hearing loss and/or sensorineural hearing loss. This study evaluated the function of the middle ear and cochlea, and the related factors. Pure tone audiometry, speech reception thresholds, speech discrimination scores, tympanometry, acoustic reflexes, and distortion product otoacoustic emissions were assessed in rheumatoid arthritis patients and healthy volunteers. Pure tone audiometry results revealed a higher bone conduction threshold in the rheumatoid arthritis group, but there was no significant difference when evaluated according to the sensorineural hearing loss definition. Distortion product otoacoustic emissions related prevalence of conductive or mixed hearing loss, tympanometry values, acoustic reflexes, and speech discrimination scores were not significantly different between the two groups. Sensorineural hearing loss was significantly more prevalent in patients who used azathioprine, cyclosporine and etanercept. Higher bone conduction thresholds in some frequencies were detected in rheumatoid arthritis patients that were not clinically significant. Sensorineural hearing loss is significantly more prevalent in refractory rheumatoid arthritis patients.

Link between rheumatoid arthritis and chronic periodontitis

Directory of Open Access Journals (Sweden)

Tomasz Kaczyński

2018-03-01

Full Text Available Chronic periodontitis is an infectious disease associated with the progressive destruction of periodontal tissues. In recent years, more and more data indicate an existing relationship between periodontal disease and rheumatoid arthritis. The link between both diseases has been confirmed in multiple studies. Despite the fact that this association might be based on shared environmental and genetic risk factors, a possible causal relation was advocated by experimental, epidemiological and interventional studies, with the leading role of Porphyromonas gingivalis. Individuals with chronic periodontitis are at an increased risk of developing rheumatoid arthritis, as well as rheumatoid arthritis patients are at an increased risk of chronic periodontitis and more severe forms of periodontitis. Furthermore, there is a correlation between the activity in both diseases – patients with more severe periodontitis suffer from more active rheumatoid arthritis. Intervention attempts were also performed, which demonstrated that eliminating periodontal infection and inflammation can affect the severity of rheumatoid arthritis. In this paper, we review the current knowledge about the link between both diseases, focusing on its clinical implications. Will periodontal treatment become a part of standard therapy for rheumatoid arthritis?

The structural features of the Fab fragments of monoclonal (Waldenstroem's disease) immunoglobulin M (IgM) and rheumatoid immunoglobulin M (IgM-RF) were studied by a complex of methods, including small-angle X-ray scattering (SAXS), electron spin resonance (ESR), and mass spectrometry (MS). The Fab-RF fragment was demonstrated to be much more flexible in the region of interdomain contacts, the molecular weights and the shapes of the Fab and Fab-RF macromolecules in solution being only slightly different. According to the ESR data, the rotational correlation time for a spin label introduced into the peptide sequence for Fab is twice as large as that for Fab-RF (21±2 and 11±1 ns, respectively), whereas the molecular weights of these fragments differ by only 0.5% (mass-spectrometric data), which correlates with the results of molecular-shape modeling by small-angle X-ray scattering. The conclusion about the higher flexibility of the Fab-RF fragment contributes to an understanding of the specificity of interactions between the rheumatoid factor and the antigens of the own organism.

Periodontal medicine defines a rapidly emerging branch of Periodontology focusing on establishing a strong relationship between periodontal health and systemic health. It is speculated that the major common dysregulation which links Periodontitis with Rheumatoid arthritis (RA) is being played by the mediators of immune inflammatory response. To determine whether there is any relationship between periodontal disease and Rheumatoid arthritis. A total of 100 patients were included for the present study which was divided into two groups: one group (cases) included 50 patients attending the Department of Orthopedics, Kasturba Medical College, Manipal who were diagnosed of Rheumatoid arthritis. Another subject population included 50 patients as controls attending the Department of Oral Medicine, Manipal College of Dental Sciences, Manipal with age and gender matched with those of rheumatoid arthritis group. Specific measures for periodontitis included plaque index, gingival index, number of missing teeth, and radiographic alveolar bone loss scores. Measures of rheumatoid arthritis included health assessment questionaires, levels of C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). Various periodontal parameters were compared between the cases and controls. The average alveolar bone loss was statistically more severe in Rheumatoid arthritis (RA) group than in the controls although there were similar plaque index in both the groups. The gingival index was statistically higher in the RA group. The Erythrocyte Sedimentation Rate (ESR) and C- Reactive Protein (CRP) levels of RA patients were also significantly associated with the severity of periodontal disease. There was a significant association between Rheumatoid arthritis and Periodontitis which may be due to a common underlying deregulation of the inflammatory response in these individuals.

Full Text Available Angiotensin II, aldosterone, and fibroblast growth factor (FGF stimulate neoangiogenesis, fibroblast proliferation, and elaboration of proinflammatory cytokines, which in turn contributes to increased pannus mass and the development of joint tissue destruction in rheumatoid arthritis (RA.Objective: to establish the specific features of changes in the blood levels of angiotensin II, aldosterone, and FGF in patients with RA in relation to the duration and severity of the disease.Subjects and methods. Examinations were made in 194 patients diagnosed with RA without comorbidity; the patients’ mean age was 47.7±10.2 years; the disease duration was 3.82±3.43 years. DAS28 scores for RA were calculated based on C-reactive protein levels. An enzyme immunoassay was used to determine the serum levels of anti-cyclic citrullinated peptide antibodies (ACCPA, angiotensin II, aldosterone, and FGF.Results and discussion. All the examinees were ascertained to have increases in the concentration of angiotensin II and aldosterone in blood by twice and in that of FGF by 2.5 times compared to the controls (p < 0.05. In patients with a RA duration of < 2 years, the blood level of angiotensin II was 25% higher than in those with a RA duration of > 5 years and the concentrations of aldosterone and FGF in patients with long-term RA were twice as high as in those with early RA. In patients with high RA activity, the blood level of angiotensin II was 1.5-fold higher than in those with low and moderate disease activity (p < 0.05. In patients with a high blood ACCPA level, the concentrations of angiotensin II, aldosterone, and FGF were 20, 30, and 25%, respectively, higher than in those with low ACCPA levels. The correlation of DAS28 with blood angiotensin II levels increased with enhanced RA activity. The high aldosterone and FGF values in RA patients are associated with the progression of joint radiographic changes.

Rheumatoid arthritis (RA) is a chronic inflammatory disease causing joint pain, loss of function and decreased health-related quality of life (HRQoL). HRQoL in RA patients is associated with several risk factors; in this paper the evidence relating to the most important risk factors is reviewed....... Modern medical therapy has improved HRQoL in RA patients, while demographic factors (female sex and older age), low socioeconomic status (in terms of education and position in the work force) and the presence of comorbid conditions appear to be associated with poorer HRQoL Udgivelsesdato: 2008/3/3...

Full Text Available In patients with rheumatoid arthritis (RA, bone fractures occur 1.5-2 times more frequently than in the population. They often lead to reduced quality of life, to disability and death in the patients. It should be noted that risk factors (RFs for fractures have not been studied on a sufficient sample in Russia; there are no recommendations on the prevention of fractures in this category of patients. Objective: to compare groups of RA patients with and without a history of fractures to further identify possible RFs for fractures. Subjects and methods. The trial included 254 patients aged 18 to 85 years, diagnosed with RA, from the database of the multicenter program «Osteoporosis in rheumatoid arthritis: Diagnosis, risk factors, fractures, treatment», who had been followed up in 2010 to 2011. The patients were divided into two groups: 1 101 (39.8% patients with a history of low-trauma fractures and 2 153 (60.2% patients without a history of fractures. In Group 1, the patients were older than in Group 2 (mean age 59.8 and 56.1 years, respectively. Menopause was recorded in 88.1 and 77.8% of cases, respectively. The groups differed in the duration of RA an average of 15.5 and 11.5 years, respectively Results. The fractures in the history were associated with the use of glucocorticoids (GC, their higher cumulative dose and use duration. In Group 1 patients, the bone mineral density (BMD was lower in all study skeleton portions and more frequently corresponded to osteoporosis. RA complications, such as amyloidosis and osteonecrosis, were more common in the patients with a history of fractures. Conclusion. In RA patients, the most likely RFs of fractures are age, the long-term intake of large-dose GC, low BMD, the severe course of RA, and the presence of its complications.

Full Text Available Objective. To study the effect of infliximab (INF on serum levels of RANKL and osteoprotegerin (OPG, as well as on structural and functional properties of the vascular wall in patients with rheumatoid arthritis (RA.Material and Methods. A total of 79 RA patients who corresponded to the classification criteria ACR (1987 or ACR/EULAR (2010 and were seronegative for IgM rheumatoid factor (RF were examined. The mean age of patients was 43.6±8.5 years. The serum levels of OPG and RANKL were determined by ELISA (Biomedica, Austria; the common carotid arteries (CCAs were visualized using an Acuson X/10 ultrasonic complex equipped with a 7 MHz linear sensor in the β-mode prior to therapy and after 12-month therapy with INF.Results and Discussion. An increased OPG level was observed mostly in patients with RA duration up to 1 year; an increase in RANKL level was pronounced stronger in patients with PA duration over 2 years. The disturbance of structural and functional properties of the arterial bloodstream was revealed, manifesting itself as an increase in the intimamedia complex thickness, diameter and rigidity index of CCA that were stronger pronounced in patients with late onset RA. A correlation analysis showed the presence of reliable relationship between the RANKL and OPG levels and CCA remodeling parameters. INF therapy showed high clinical effectiveness and correction effect on the RANKL/OPG system. In addition, it was accompanied by a reduction of signs of CCA remodeling, which was stronger pronounced in patients with early RA.Conclusion. The results prove the reasonability of using INF at early stages of RA in order to optimize the therapy and achieve more efficient control of cardiovascular complications.

Factors influencing the patient with rheumatoid arthritis in their decision to seek podiatry.

Despite the level of foot involvement in rheumatoid arthritis (RA), and the literature to support early assessment of foot care needs, local referral of patients to podiatry has been occurring too late to instigate certain preventative interventions. Preliminary fieldwork has highlighted that the primary responsibility for the instigation of this lies with the patient. The present study describes the factors that influence the patient with RA in their decision to self-report foot problems. A case study research strategy was employed. Nine patients attending the outpatient rheumatology department participated in the study and data were gathered through semi-structured interviews. This information was analysed using a framework approach. The key themes derived from the data suggested that there are a variety of factors influencing the patient's decision to self-report foot concerns. Some will act to encourage the action and others will act to oppose it. Other factors can influence the decision either way, depending on the individual patient (psychological state, previous experience, body image changes). In addition, age, gender, and cultural and social aspects are also significant. Due to the multitude of factors influencing the individual's decision to seek help, the patient cannot be given sole responsibility for their foot health if we wish to achieve timely and appropriate podiatry, as recommended in the literature. Responsibility should be three-way; the patient, the members of the rheumatology team and, once in the podiatry service, the podiatrist should maintain this. Copyright © 2013 John Wiley & Sons, Ltd.

Long since it have been suggested that a subpopulation of patients with rheumatoid arthritis, diagnosed with negative rheumatoid factor tests, represents a clinical entity quite distinct from that of seropositive rheumatoid arthritis (RA). Our aim was to establish a scientific comparative analysis between seronegative and seropositive rheumatoid arthritis, regarding some radiological and clinical parameters, applied for the first time on patients from Kosovo. Two hundred fifty patients with rheumatoid arthritis according to the American College of Rheumatology criteria were retrospectively studied by analysis the radiographic damage and clinical parameters of the disease, using a data base. All examinees were between 25-60 years of age (Xb=49.96, SD=10.37) with disease duration between 1-27 years (Xb = 6.41, SD=6.47). All patients underwent a standardised evaluation radiographs. Baseline standardised poster anterior radiographs of hands and feet and radiographs of other joints, depending on indications, were assessed. Erythrocyte sedimentation rate values correlated with the radiological damages and statistical difference was found for seronegative subset (r=0.24, p<0.01). Longer duration of the disease resulted in the increase of radiological changes in both subsets (r=0.66, p<0.01) seronegative, (r=0.49, p<0.01) seropositive. Anatomic changes of IInd and IIIrd level were nearly equally distributed in both subsets, 76 (60.8%) seronegative, 75 (60%) seropositive. Radiological damages are nearly equal in both subsets, elevate in relation to the duration of the disease and correlate with ESR values. Regarding the sero-status, differences within sex, with some exceptions, are not relevant. Although there are some definite quantitative and qualitative differences regarding sero-status, obviously there is a great deal of overlap between the two groups.

Full Text Available Juvenile rheumatoid arthritis (JRA is the most common rheumatic condition in children. JRA is defined as persistent arthritis in 1 or more joints for at least 6 weeks, with the onset before age 16 years. The etiology of JRA is unknown. Antigen activated CD4+ T cell stimulate monocytes, macrophages, and synovial fibroblasts to produce the cytokines Interleukin-1 (IL-1, IL-6, and tumor necrosis factor ? (TNF-? and to secrete matrix metalloproteinases, which lead to chronic inflammation due to infiltration of inflammatory cell, angiogenesis, destruction of cartilage and bone with pannus formation. The 3 major subtypes of JRA are based on the symptoms at disease onset and are designated systemic onset, pauciarticular onset, and polyarticular onset. For all patients, the goals of therapy are to decrease chronic joint pain and suppress the inflammatory process. Poor prognostic have been observed in patients with polyarticular onset, rheumatoid factor, persistent morning stiffness, tenosynovitis, involvement of the small joints, rapid appearance of erosions, active late onset childhood, subcutaneous nodules, or antinuclear antibody.

Full Text Available Rheumatoid arthritis (RA is a chronic systemic inflammatory disease, characterised by polyarthritis and extra-articular organ disease, including rheumatoid nodules, ophthalmologic manifestations, cardiopulmonary disease, vasculitis, neuropathy, glomerulonephritis, Felty’s syndrome, and amyloidosis. Extra-articular manifestations of RA (ExRA occur in 17.8–40.9% of RA patients, 1.5–21.5% of them presenting as severe forms and usually associated with increased morbidity and mortality. They can develop at any time during the course of the disease, even in the early stages, and are associated with certain predisposing factors, such as the presence of rheumatoid factor, smoking, and long-standing severe disease. Rheumatoid nodules, the most common ExRA, have been found to be associated with the development of severe features, such as vasculitis, rheumatoid lung disease, pericarditis, and pleuritis, especially in those patients who develop them within 2 years from RA diagnosis. There is no uniformity in the definition of the term ExRA, which limits comparability between different studies. Several recent surveys suggest a lower frequency, probably due to a better control of disease activity. Diagnosis of ExRA is a challenge for clinicians, given its variable and complex presentation, and the lack of specific diagnostic tests; it must be based on clinical recognition and exclusion of other causes of the signs and symptoms. Furthermore, management continues to be difficult with a bad prognosis in many conditions. This article reviews the clinical aspects of major ExRA, focusing on incidence, clinical features, and therapeutic approaches, and how modern immunosuppressive therapy can change the outcome.

1980-01-01

In 188 patients with rheumatoid arthritis 564 radiologic examinations of the sacroiliac joints were performed. Severe blurring of the joint space or ankylosis were uncommon. The involvement was related to an age > 40 years at the onset, high values of the ESR and involvement of most joint groups in the limbs and cervical spine. Sex, presence or high titres of the rheumatoid factor and antinuclear antibodies were unrelated to lesions of the sacroiliac joints. A relation to the severity of rheumatoid arthritis rather than to the immunologic condition is suggested. (Auth.)

Rheumatoid arthritis is a systemic disorder where clinically significant renal involvement is relatively common. However, crescentic glomerular nephritis is a rarely described entity among the rheumatoid nephropathies. We report a case of a patient with rheumatoid arthritis presenting with antineutrophil cytoplasmic antibody-negative crescentic glomerular nephritis. A 54-year-old Sri Lankan woman who had recently been diagnosed with rheumatoid arthritis was being treated with methotrexate 10 mg weekly and infrequent nonsteroidal anti-inflammatory drugs. She presented to our hospital with worsening generalized body swelling and oliguria of 1 month's duration. Her physical examination revealed that she had bilateral pitting leg edema and periorbital edema. She was not pale or icteric. She had evidence of mild synovitis of the small joints of the hand bilaterally with no deformities. No evidence of systemic vasculitis was seen. Her blood pressure was 170/100 mmHg, and her jugular venous pressure was elevated to 7 cm with an undisplaced cardiac apex. Her urine full report revealed 2+ proteinuria with active sediment (dysmorphic red blood cells [17%] and granular casts). Her 24-hour urinary protein excretion was 2 g. Her serum creatinine level was 388 μmol/L. Abdominal ultrasound revealed normal-sized kidneys with acute parenchymal changes and mild ascites. Her renal biopsy showed renal parenchyma containing 20 glomeruli showing diffuse proliferative glomerular nephritis, with 14 of 20 glomeruli showing cellular crescents, and the result of Congo red staining was negative. Her rheumatoid factor was positive with a high titer (120 IU/ml), but results for antinuclear antibody, double-stranded deoxyribonucleic acid, and antineutrophil cytoplasmic antibody (perinuclear and cytoplasmic) were negative. Antistreptolysin O titer rheumatoid arthritis, awareness of which would facilitate early appropriate investigations and treatment.

Association of MASP-2 levels and MASP2 gene polymorphisms with rheumatoid arthritis in patients and their relatives.

Directory of Open Access Journals (Sweden)

Isabela Goeldner

Full Text Available BACKGROUND: Mannan-binding lectin-associated serine protease 2 (MASP-2 is a key protein of the lectin pathway of complement. MASP-2 levels have been associated with different polymorphisms within MASP2 gene as well as with the risk for inflammatory disorders and infections. Despite its clinical importance, MASP-2 remains poorly investigated in rheumatoid arthritis (RA. METHODS: In this case-control study, we measured MASP-2 serum levels in 156 RA patients, 44 patient relatives, and 100 controls from Southern Brazil, associating the results with nine MASP2 polymorphisms in all patients, 111 relatives, and 230 controls genotyped with multiplex SSP-PCR. RESULTS: MASP-2 levels were lower in patients than in controls and relatives (medians 181 vs. 340 or 285 ng/ml, respectively, P<0.0001. Conversely, high MASP-2 levels were associated with lower susceptibility to RA and to articular symptoms independently of age, gender, ethnicity, smoking habit, anti-CCP and rheumatoid factor positivity (OR = 0.05 [95%CI = 0.019-0.13], P<0.0001 between patients and controls; OR = 0.12, [95%CI = 0.03-0.45], P = 0.002 between patients and relatives; OR = 0.06, [95%CI = 0.004-0.73], P = 0.03 between relatives with and without articular symptoms. MASP2 haplotypes *2A1 and *2B1-i were associated with increased susceptibility to RA (OR = 3.32 [95%CI = 1.48-7.45], P = 0.004. Deficiency-causing p.120G and p.439H substitutions were associated with five times increased susceptibility to articular symptoms in relatives (OR = 5.13 [95%CI = 1.36-20.84], P = 0.02. There was no association of MASP-2 levels or MASP2 polymorphisms with autoantibodies, Sjögren's syndrome, nodules and functional class. CONCLUSIONS: In this study, we found the first evidence that MASP-2 deficiency might play an important role in the development of RA and articular symptoms among relatives of RA patients.

Liver enlargement demonstrated by scintigraphy in rheumatoid arthritis

1976-03-01

Scintigraphic scanning employing technetium-99m sulfur colloid was used to assess the size of the liver and spleen in 32 consecutive patients with rheumatoid arthritis. The data were correlated with clinical and laboratory assessment. Seven patients had enlarged livers, three enlarged spleens. An expected correlation of liver enlargement with Sjogren's syndrome did not materialize. Splenic enlargement and liver enlargement were discordant. Liver enlargement correlation best with elevations of rheumatoid factor as measured by latex fixation. As liver enlargement is not an appreciated feature of rheumatoid arthritis, these findings suggest that hepatomegaly need not necessarily imply adverse treatment results or the development of lymphoproliferative disorders.

Minimizing disability and enhancing physical function to its optimal levels is still a challenge in management of rheumatoid arthritis (RA). The aim is to identify factors leading to disability in RA. This is a cross-sectional Egyptian multicenter study carried out on 215 RA patients attending to our inpatient and outpatient rheumatology clinics during 4 months starting from April to July 2017 who agreed to participate in the study; 170 patients were from Cairo University hospitals and 45 from Zagazig University hospitals. We recorded a number of possible risk factors including demographic, clinical, serological and therapeutic factors. The assessment of patients' disability was done using Modified HAQ (MHAQ). A significant positive correlation was found between MHAQ and different markers of activity in addition to age and depression score (P<0.001). Illiteracy accounted for higher MHAQ scores (P=0.001). A higher MHAQ was found in patients with ischemic heart disease (P<0.05). Patients with erosions on X-rays had significantly higher MHAQ scores. Subluxations also accounted for higher MHAQ scores (P=0.000). Aging, illiteracy, disease activity, erosions, subluxations, depression and ischemic heart disease were all related to higher disability. Good control of disease activity which in turn reduces erosions and subluxations is mandatory. Screening for depression and proper use of anti-depressants is of great value. Proper screening and prophylaxis is recommended against ischemic heart disease by controlling modifiable risk factors like obesity, dyslipidaemia, hypertension, smoking and sedentary lifestyle.

Jambale Triveni A, Halyal SS, Jayaprakash Murthy DS

2014-04-01

Full Text Available Background: Rheumatoid arthritis (RA is a chronic progressive autoimmune disorder characterized by symmetric erosive synovitis and sometimes shows multisystem involvement. The long-term outcome of the disease is characterized by significant morbidity and increased mortality. Elevated free radical generations in inflamed joints and impaired antioxidant system have been implicated in RA. Nitric oxide (NO can also induce tissue damage, especially after conversion into peroxynitrite radical (ONOO·. Aims: To estimate the serum levels of MDA, Nitric Oxide (NO and Vitamin E in patients with Rheumatoid Arthritis. Materials and Methods: The study includes 50 RA patients who were fulfilling the American Rheumatism Association 1987 revised criteria for classification of RA and 50 age and sex matched healthy subjects without any major illness were considered as controls. MDA, NO and Vitamin E were estimated in serum. Results: The estimated mean levels (mean ± SD of serum MDA, NO, Vitamin E, in control group were 3.55 ± 0.30, 36.23 ± 7.03, 14.61 ± 1.74, respectively and in patients with RA they were 5.39 ± 0.79, 78.81 ± 8.56, 10.56 ± 1.72, respectively. The statistical analysis by unpaired t-test shows that the levels of serum MDA and NO significantly increased (p< 0.001 and the vitamin E levels were significantly decreased (p < 0.001 in RA patients when compared to healthy controls. Conclusion: The serum values of MDA, NO and Vitamin E all together provided fairly useful index of oxidative stress in RA patients. The results of current study support the concept of oxidative stress leading to tissue damage.

Objective: To determine the clinical value of measurement of serum cytidine deaminase (CD) levels in patients with active rheumatoid arthritis (RA). Methods: Serum levels of CD were detected with spectrophotometry, in 33 patients with active RA and 60 controls. The erythrocyte sedimentation rate (ESR) and CRP content were also determined in both groups. Results: The ser- um CD contents in patients with active RA(14.80 ± 2.11U/ml) were significantly higher than those in controls(4.86±1.86 U/ml,P<0.01). The CRP contents (51.46 ± 20.43mg/L) and ESR readings(85.03 ± 27.6mm/h) in the patients were also significantly higher than those in the controls(3.40 ± 2.21mg/L and 13.04 ± 4.89mm/h respectively, all P<0.01). In the patients, the serum CD contents were linearly positively correlated with the ESR contents and CRP readings (r=0.6324 and 0.8013 respectively, P <0.01). Conclusion: Serum CD is an early biochemical marker for diagnosis of active rheumatoid arthritis and is also of prognostic value. (authors)

Fatigue and sleep quality in rheumatoid arthritis patients during hospital admission.

Science.gov (United States)

Szady, Paulina; Bączyk, Grażyna; Kozłowska, Katarzyna

2017-01-01

Rheumatoid arthritis (RA) is a systemic disease of connective tissue characterised by chronic course with periods of exacerbation and remission. Even in the early stages of the disease patients report the occurrence of fatigue and sleep disorders. Reduced sleep quality and chronic fatigue are common among patients with rheumatoid arthritis. The aim of the research was to evaluate the severity of fatigue and sleep quality assessment among patients hospitalised with rheumatoid arthritis and to determine the relation between the level of symptoms of fatigue and sleep quality and variables such as: age, gender, disease duration, marital status, applied pharmacological treatment, and pain intensity. The study involved 38 patients (12 men and 26 women) hospitalised in the Rheumatologic Ward of the Orthopaedics and Rehabilitation Hospital of the University of Medical Sciences. The average age of the entire group was 56.26 years. Fatigue was evaluated with use of Polish version of Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), while in order to evaluate sleep quality within the examined group of patients the Pittsburgh Sleep Quality Index (PSQI) was used. Patients with rheumatoid arthritis in the analysed group have lower sleep quality, and within subjects with such a diagnosis the fatigue is present. The relation was found between fatigue and such variables as: age, illness duration, marital status, applied pharmacological treatment, and severity of pain. Sleep quality within patients with RA is correlated by such variables as: age, gender, applied pharmaceutical treatment, and severity of pain. It was identified that patients with lower sleep quality experience increased levels of fatigue. There is a need to clarify which factors determine the level of fatigue and sleep quality in patients suffering from RA in future population-based research and to indicate to doctors, nurses, psychologists, and physiotherapists the significance and importance of

Background Interleukin-17 (IL-17), a cytokine mainly secreted by Th17 cells, seems to play a significant role in the pathogenesis of rheumatoid arthritis (RA). Functional genetic polymorphisms in IL-17 and its receptor genes can influence either qualitatively or quantitatively their functions. Therefore, we aimed to study the impact of IL17-A and IL17RC polymorphisms on plasma level of IL-17 and RA susceptibility and severity. Methods In this context, IL-17A*rs2275913 and IL-17RC*rs708567 polymorphisms were investigated together with the quantification of IL17 plasma level in 115 RA patients and 91 healthy control subjects matched in age, sex and ethnic origin. Results There were no statistically significant associations between IL-17A and IL-17RC studied polymorphisms and RA susceptibility. In contrast, IL-17A plasma levels were significantly higher in patients (55.07 pg/ml) comparatively to controls (4.75 pg/ml), p<10E-12. A ROC curve was used to evaluate the performance of plasma IL-17 in detecting RA. Given 100% specificity, the highest sensitivity of plasma IL-17A was 61.7% at a cut-off value of 18.25 pg/ml; p < 10E-21, CI = [0.849–0.939]. Analytic results showed that the IgM-rheumatoid factor and anti-CCP antibodies were significantly less frequent in patients with the IL-17RC*A/A genotype than those carrying *G/G and *G/A genotypes; p = 0.013 and p = 0.015, respectively. Otherwise, IL-17 plasma levels’ analysis showed a significant association with the activity of RA (DAS28≥5.1 = 74.71 pg/ml vs. DAS28<5.1 = 11.96 pg/ml), p<10E-6. Conclusion IL-17A*rs2275913 (G/A) and IL-17RC*rs708567 (G/A) polymorphisms did not seem to influence RA susceptibility in Tunisian population. This result agrees with those reported previously. Plasma IL-17A level seems to be predictive of severe RA occurrence. PMID:29584788

Background: Osteoporosis is an early and common feature in rheumatoid arthritis. Apart from other manifestations, Osteoporosis is an extra-articular manifestation of rheumatoid arthritis which may result in increased risk of fractures, morbidity, mortality, and associated healthcare costs. This study evaluates bone mineral density changes in patients with rheumatoid arthritis of recent-onset. Methods: This descriptive case series was conducted in the Rheumatology Department of a tertiary care hospital in Karachi. Data was prospectively collected from 76 patients presenting with seropositive or seronegative rheumatoid arthritis. Bone mineral density of these patients measured at lumbar spine and hip by using dual energy x-ray absorptiometry scan. Variables like age, gender, BMI, menstrual status, disease duration, erythrocyte sedimentation rate, vitamin D level, clinical disease activity index and seropositivity for rheumatoid arthritis were measured along with outcome variables. Results: A total of 104 patients fulfilling inclusion criteria were registered with 28 excluded from study. Among the remaining 76 patients, 68 (89.50 percentage) were female, with mean age of patients (with low bone mineral density) as 50.95±7.87 years. Nineteen (25 percentage) patients had low bone mineral density, 68.52 percentage had low BMD at spine while 10.52 percentage at hip and 21.05 percentage at spine and hip both. Low bone mineral density was found higher in patients with seronegative 7 (50 percentage) as compared to seropositive patients 12 (19.4 percentage) (p-value 0.017), whereas low bone mineral density was found higher 12 (70.6 percentage) among post-menopausal women. Conclusion: Low BMD was found in 25 percentage of patients at earlier stage of the rheumatoid arthritis with seropositivity, age and menopausal status as significant risk factors. (author)

The efficacy of B cell-depleting therapies for rheumatoid arthritis underscores antibody-independent functions of effector B cells such as cognate T-B interactions and production of pro-inflammatory cytokines. Receptor activator of nuclear factor κB ligand (RANKL) is a key cytokine involved in bone destruction and is highly expressed in synovial fluid B cells in patients with rheumatoid arthritis. In this study we sought to clarify the generation mechanism of RANKL(+) effector B cells and their impacts on osteoclast differentiation. Peripheral blood and synovial fluid B cells from healthy controls and patients with rheumatoid arthritis were isolated using cell sorter. mRNA expression of RANKL, osteoprotegerin, tumor necrosis factor (TNF)-α, and Blimp-1 was analyzed by quantitative real-time polymerase chain reaction. Levels of RANKL, CD80, CD86, and CXCR3 were analyzed using flow cytometry. Functional analysis of osteoclastogenesis was carried out in the co-culture system using macrophage RAW264 reporter cells. RANKL expression was accentuated in CD80(+)CD86(+) B cells, a highly activated B-cell subset more abundantly observed in patients with rheumatoid arthritis. Upon activation via B-cell receptor and CD40, switched-memory B cells predominantly expressed RANKL, which was further augmented by interferon-γ (IFN-γ) but suppressed by interleukin-21. Strikingly, IFN-γ also enhanced TNF-α expression, while it strongly suppressed osteoprotegerin expression in B cells. IFN-γ increased the generation of CXCR3(+)RANKL(+) effector B cells, mimicking the synovial B cell phenotype in patients with rheumatoid arthritis. Finally, RANKL(+) effector B cells in concert with TNF-α facilitated osteoclast differentiation in vitro. Our current findings have shed light on the generation mechanism of pathogenic RANKL(+) effector B cells that would be an ideal therapeutic target for rheumatoid arthritis in the future.

2015-10-15

Rheumatoid arthritis (RA) is a challenging autoimmune disorder, whose treatments usually cause severe gastrointestinal, renal and other complications. We aimed to evaluate the beneficial anti-arthritic effects of an angiotensin converting enzyme (ACE) inhibitor, ramipril and a dopamine receptor blocker, haloperidol, on Complete Freund's Adjuvant-induced RA in adult female albino rats. Rats were allocated into a normal control group, an arthritis control group, two reference treatment groups receiving dexamethasone (1.5 mg/kg/day) and methotrexate (1 mg/kg/day), and two treatment groups receiving ramipril (0.9 mg/kg/day) and haloperidol (1 mg/kg/day). Serum rheumatoid factor, matrix metalloprotinease-3 (MMP-3) and cartilage oligomeric matrix protein as specific rheumatoid biomarkers, serum immunoglobulin G and antinuclear antibody as immunological biomarkers, serum tumor necrosis factor alpha (TNF-α) and interleukin-10 (IL-10) as immunomodulatory cytokines, serum myeloperoxidase and C-reactive protein as inflammatory biomarkers, as well as malondialdehyde and glutathione reduced (GSH) as oxidative stress biomarkers were assessed. A histopathological study on joints and spleens was performed to support the results of biochemical estimations. Ramipril administration significantly corrected all the measured biomarkers, being restored back to normal levels except for MMP-3, TNF-α and IL-10. Haloperidol administration restored all the measured biomarkers back to normal levels except for TNF-α, IL-10 and GSH. In conclusion, ACE inhibitors represented by ramipril and dopamine receptor blockers represented by haloperidol may represent new promising protective strategies against RA, at least owing to their immunomodulatory, anti-inflammatory and antioxidant potentials.

2014-07-01

Full Text Available Objective: to assess the rate of silent myocardial ischemia (SMI and the pattern of cardiac rhythm disturbances in women with rheumatoidarthritis (RA, their association with traditional risk factors (TRF for cardiovascular diseases (CVD, with subclinical structural and functionalchanges in the heart and vessels, with the activity and severity of rheumatoid inflammation.Subjects and methods. Two hundred and ninety-one female patients aged less than 60 years with a valid diagnosis of RA and no clinicalsigns were examined. A control group consisted of 125 women without rheumatic diseases. In addition to the clinical manifestations, activity,and severity of RA, the authors assessed major TRFs for CVD, performed Holter ECG monitoring, common carotid artery duplex scanning, transthoracic echocardiographic study, and determined the levels of serum inflammatory markers.Results. The women with RA differ from the control group in the higher incidence of SMI, supraventricular arrhythmias (SVA and highgradepremature ventricular contractions (PVC. The patients with RA and SMI are characterized in terms of age-adjustment by higher disease activity (DAS28, systemic manifestations, cumulative larger-dose glucocorticoids (GC and a higher percentage of patients receiving disease-modifying anti-rheumatic drugs as compared with those with RA and no SMI with adjustment for age. High disease activity(DAS28, level of inflammatory markers, IgM rheumatoid arthritis seropositivity, and GC therapy are SVA-associated factors in women with RA; larger left ventricular end-diastolic dimension and serositis are factors associated with high-grade PVC.Conclusion. The RA women without clinical manifestations of CVD are recorded to have high rates of SMI, SVA, and high-grade PVC, which is primarily due to the activity and severity of rheumatoid inflammation.

2006-02-28

The goal of the present study is to evaluate the usefulness of synovectomy of the knee joint in patients with rheumatoid arthritis. Synovectomy of the knee is the most common lower limb operation performed in patients with rheumatoid arthritis. Depending on the stage of the disease, the symptoms, and the degree of intra-articular changes in the radiological image, there are indications for performing both early and late synovectomy. The progress of the disease is not dependent on its duration, but on the aggressiveness and dynamics of the rheumatoid process. The authors present the advantages of early synovectomy, which halts the progress of the disease and protects the joint from destruction. After early synovectomy one obtains an average of 75% good outcomes, while after late synovectomy the percentage of positive outcomes is about 70%. The authors point out the effectiveness and low level of invasiveness of arthroscopic synovectomy, thanks to which the progress of the disease can be checked and monitored. Another possible therapy is chemical synovectomy, with the specific action of radioisotopes: synoviorthosis with laser irradiation. The authors emphasize that an important factor in obtaining good outcome after every synovectomy is rehabilitation, during which the range, frequency of exercise, and physicotherapeutic procedures are established, depending on the stage of advancement of the rheumatoid process.

Cachexia and adiposity in rheumatoid arthritis. Relevance for disease management and clinical outcomes.

Science.gov (United States)

2016-03-01

Altered body composition is a frequent finding in rheumatoid arthritis and is associated with the two major outcomes of the disease: disability and cardiovascular mortality. It is estimated that up to two thirds of patients may be affected by loss of lean mass, the so-called rheumatoid cachexia. Hence, body weight being equal, the relative amount of lean mass is lower and that of body fat is higher in rheumatoid arthritis patients vs. healthy controls. Both disease-related factors and other factors, like drug treatments, physical activity and nutrition contribute to modify body composition in rheumatoid arthritis. The effect of pharmacological treatments, and notably of anti-TNF drugs, on body composition is controversial. Conversely, training programs to stimulate muscle growth can restore lean mass and reduce adiposity. There is good evidence that amelioration of body composition ameliorates function and reduces disability. Currently, there is no evidence that interventions that modify body composition can reduce cardiovascular morbidity and mortality in rheumatoid arthritis. Copyright © 2015.

[Dyslipidemia and atherogenic risk in patients with rheumatoid arthritis].

Science.gov (United States)

Batún Garrido, José Antonio de Jesús; Olán, Francisco; Hernández Núñez, Éufrates

2016-01-01

Dyslipidaemia is one of the main risk factors for atherosclerotic cardiovascular disease. Patients with rheumatoid arthritis have 2-3 times more cardiovascular risk, which is partly due to the pattern of lipids which increase the atherogenic index. A descriptive, cross-sectional, observational and prospective study was conducted on 82 patients, selected for their lipid profile. Variables associated with the disease and the drugs used were recorded. Atherogenic risk was calculated, with Chi square being used for categorical variables, and the Mann-Whitney test for the continuous ones. The dyslipidaemia frequency was 54.9%. The most frequent age range of dyslipidaemia was between 51 and 60 years. Patients with type i obesity had a higher frequency of dyslipidaemia. Less dyslipidaemia was found with a lower rate of disease activity. Patients with cyclic citrullinated anti-peptide antibodies and positive rheumatoid factor, erythrocyte sedimentation rate>13mm or CRP>2mg/L had a higher frequency of dyslipidaemia. The mean Castelli atherogenic index was 4.36, the index of Kannel was 2.59, and triglycerides/HDL-c ratio was 3.83.Patients with dyslipidaemia showed a higher frequency of positive rheumatoid factor (P=.0008), and those patients who were taking hydroxychloroquine had a lower frequency of dyslipidaemia P=.03. Patients with rheumatoid arthritis have a pro-atherogenic lipid profile. It is important to know this and treat it to reduce cardiovascular risk.

2015-01-01

Full Text Available Objective: to study the actual intake of vitamins and calcium and their provision in rheumatoid arthritis (RA in the Middle Urals. Subjects and methods. The case-control method was used to form 150 pairs of RA patients aged 55.31±11.3 years. Their actual nutrition was studied from the frequency of food intake for a month, by applying a questionnaire. Based on the obtained food consumption data, the authors calculated the daily intake of vitamins A, B2, C, E, β-carotene, and calcium. The plasma levels of these factors were measured in 40% of the random patient sample and in 68 (45% control persons. A complete clinical examination included the evaluation of patients' general health and articular status, inflammatory activity assessment with DAS28, laboratory tests (general blood and urine analyses, estimation of the levels of transaminases, creatinine, electrolytes, C-reactive protein, and rheumatoid factor, and instrumental examination, involving electrocardiography and joint X-ray. Results and discussion. The study demonstrated that actual nutrition was depleted of vitamins A, C, and B2 in the patients with RA as compared to the controls. Inadequate provision of vitamin C, β-carotene, riboflavin, and calcium was found in RA. The inconsistency between the consumption of vitamins C, B2, and β-carotene and their plasma levels could suggest increased demands for these nutrients in RA. The findings should undergo detailed studies; first of all, this concerns the comparison of intake of the nutrients and their provision with the most important clinical characteristics of RA, such as duration, progression, activity, X-ray stage, and the presence of rheumatoid factor. The knowledge of these matters could, in our opinion, improve the results of therapy and prognosis in RA.

The Study Group for Risk Factors for Rheumatoid Arthritis was established by the EULAR Standing Committee on Investigative Rheumatology to facilitate research into the preclinical and earliest clinically apparent phases of rheumatoid arthritis (RA). This report describes the recommendation for terminology to be used to define specific subgroups during different phases of disease, and defines the priorities for research in this area. Terminology was discussed by way of a three-stage structured process: A provisional list of descriptors for each of the possible phases preceding the diagnosis of RA were circulated to members of the study group for review and feedback. Anonymised comments from the members on this list were fed back to participants before a 2-day meeting. 18 participants met to discuss these data, agree terminologies and prioritise important research questions. The study group recommended that, in prospective studies, individuals without RA are described as having: genetic risk factors for RA; environmental risk factors for RA; systemic autoimmunity associated with RA; symptoms without clinical arthritis; unclassified arthritis; which may be used in a combinatorial manner. It was recommended that the prefix ‘pre-RA with:’ could be used before any/any combination of the five points above but only to describe retrospectively a phase that an individual had progressed through once it was known that they have developed RA. An approach to dating disease onset was recommended. In addition, important areas for research were proposed, including research of other tissues in which an adaptive immune response may be initiated, and the identification of additional risk factors and biomarkers for the development of RA, its progression and the development of extra-articular features. These recommendations provide guidance on approaches to describe phases before the development of RA that will facilitate communication between researchers and comparisons between

Characterization of rheumatoid arthritis subtypes using symptom profiles, clinical chemistry and metabolomics measurements.

Directory of Open Access Journals (Sweden)

Herman A van Wietmarschen

Full Text Available OBJECTIVE: The aim is to characterize subgroups or phenotypes of rheumatoid arthritis (RA patients using a systems biology approach. The discovery of subtypes of rheumatoid arthritis patients is an essential research area for the improvement of response to therapy and the development of personalized medicine strategies. METHODS: In this study, 39 RA patients are phenotyped using clinical chemistry measurements, urine and plasma metabolomics analysis and symptom profiles. In addition, a Chinese medicine expert classified each RA patient as a Cold or Heat type according to Chinese medicine theory. Multivariate data analysis techniques are employed to detect and validate biochemical and symptom relationships with the classification. RESULTS: The questionnaire items 'Red joints', 'Swollen joints', 'Warm joints' suggest differences in the level of inflammation between the groups although c-reactive protein (CRP and rheumatoid factor (RHF levels were equal. Multivariate analysis of the urine metabolomics data revealed that the levels of 11 acylcarnitines were lower in the Cold RA than in the Heat RA patients, suggesting differences in muscle breakdown. Additionally, higher dehydroepiandrosterone sulfate (DHEAS levels in Heat patients compared to Cold patients were found suggesting that the Cold RA group has a more suppressed hypothalamic-pituitary-adrenal (HPA axis function. CONCLUSION: Significant and relevant biochemical differences are found between Cold and Heat RA patients. Differences in immune function, HPA axis involvement and muscle breakdown point towards opportunities to tailor disease management strategies to each of the subgroups RA patient.

Characteristics of Rheumatoid Arthritis relative to HLA-DR in Saudi Arabia

The objective was to determine the clinical characteristics of rheumatoid arthritis in Saudi Arabia in relation to human leukocyte antigen type. A group of 91 rheumatoid arthritis patients, 72 females and 19 males were studied for the various clinical, laboratory and radiological parameters along with human leukocyte antigen-DR phenotypes. Since human leukocyte antigen-DR10 was most commonly associated with rheumatoid arthritis in our population, we compared those patients with human leukocyte antigen-DR10 to those without. The comparison yielded differences in the presence of rheumatoid nodules, erosions, corticosteroid treatment, and joint involvement at presentation, hemoglobin levels, and white cell count. Only the last 3 parameters showed a statistical significance. Human leukocyte antigen type of Saudi patients with rheumatoid arthritis influenced the course of the disease but only to a limited extent. (author)

1996-01-01

Purpose: It has been the aim of the following study to evaluate pulmonary changes in rheumatoid arthritis with high-resolution CT and to assess their correlation with joint manifestation and laboratory paramters. Material and methods: The authors prospectively performed computed tomography (CT) in 83 patients with rheumatoid arthritis and graded pulmonary changes for frequency and severity. Included were patients with 6-7/7 ARA, BSR>25/1 min and mean disease duration of 12 years (range, 1-44). Data of medical and drug histories, smoking habits, blood levels of rheumatoid factor (RF), antinuclear antibodies (ANA) and C-reactive protein as well as the degree of joint involvement were taken into account. Results: 58 patients (70%) had pathological CT scans showing the following abnormalities: Interlobular thickening (44.5%), intralobular thickening (34%), nonseptal linear attenuation (35%), nodular or linear pleural thickening (32.5%), ground-glass pattern (19%), centrilobular nodules (13%), honeycombing (13%) and bronchiolectasis (9%). Intralobular thickening, honeycombing and pleural thickening were associated with a higher degree of joint manifestation; pleural thickening, honeycombing and ground-glass pattern were associated with a higher level of rheumatoid factor. There was no relationship between pulmonary changes and either the duration of the disease, antinuclear antibodies (ANA) or C-reactive protein. Conclusion: CT may be a useful noninvasive tool for recognition of RA-associated lung disease. Interstitial lung changes are frequent and they are independent of the duration of the disease. Pulmonary interstitial changes are more frequent and more severe in RF-positive patients and in case of more severe joint involvement. (orig.) [de

2009-01-01

Patients with end-stage renal disease (ESRD) and on hemodialysis (HD) are at increased risk for developing rheumatoid arthritis (RA), as a result of defective immunity. Our aim was to examine if ESRD and the length of HD treatment impact the clinical utility of antibodies to cyclic citrullinated peptides (anti-CCP) and rheumatoid factor (RF) as diagnostic tools for RA. We included 94 subjects in our study: 37 healthy volunteers and 57 patients with ESRD who had been undergoing HD for 1-12 years, and without confirmed RA. In order to test our hypothesis, we measured and correlated anti-CCP and RF as laboratory markers of RA. Our study showed that there is no significant difference between values for anti-CCP (p=0.11) and RF (p=0.98) in control subjects as well as in patients undergoing HD, regardless of the length of time that patients had been undergoing HD treatment. Our study indicates that HD does not impair the specificity of anti-CCP and RF for RA in patients where the disease has not yet developed. Future prospective studies may show whether there is any use in determinating RF, and especially anti-CCP, as early predictors of RA in patients with ESRD who are at greater risk of developing this condition.

Introduction There is increasing evidence that autoantibodies and immune complexes (ICs) contribute to synovitis in rheumatoid arthritis (RA), yet the autoantigens incorporated in ICs in RA remain incompletely characterised. Methods We used the C1q protein to capture ICs from plasma derived from human RA and control patients. Antibodies specific for immunoglobulin were used to detect ICs, and fibrinogen antibodies were used to detect fibrinogen-containing ICs. RA and control plasma were separated by liquid chromatography, and fractions then characterised by ELISA, immunoblotting and mass spectrometry. Immunohistochemical staining was performed on rheumatoid synovial tissue. Results C1q-immunoassays demonstrated increased levels of IgG (p = 0.01) and IgM (p = 0.0002) ICs in plasma derived from RA patients possessing anti-cyclic citrullinated peptide (CCP+) autoantibodies as compared with healthy controls. About one-half of the anti-CCP+ RA possessed circulating ICs containing fibrinogen (p = 0.0004). Fractionation of whole RA plasma revealed citrullinated fibrinogen in the high molecular weight fractions that contained ICs. Positive correlations were observed between fibrinogen-containing ICs and anti-citrullinated fibrinogen autoantibodies, anti-CCP antibody, rheumatoid factor and certain clinical characteristics. Immunohistochemical staining demonstrated co-localisation of fibrinogen, immunoglobulin and complement component C3 in RA pannus tissue. Mass spectrometry analysis of immune complexes immunoprecipitated from RA pannus tissue lysates demonstrated the presence of citrullinated fibrinogen. Conclusion Circulating ICs containing citrullinated fibrinogen are present in one-half of anti-CCP+ RA patients, and these ICs co-localise with C3 in the rheumatoid synovium suggesting that they contribute to synovitis in a subset of RA patients.

Thoracic complications of rheumatoid disease

International Nuclear Information System (INIS)

Massey, H.; Darby, M.; Edey, A.

2013-01-01

Rheumatoid arthritis is a relatively common multisystem disease associated with significant mortality and morbidity. Thoracic disease, both pleural and pulmonary, is a frequent extra-articular manifestation of rheumatoid arthritis and responsible for approximately 20% of rheumatoid-associated mortality. Rheumatoid disease and its associated therapies can affect all compartments of the lung inciting a range of stereotyped pathological responses and it is not infrequent for multiple disease entities to co-exist. In some instances, development of pulmonary complications may precede typical rheumatological presentation of the disease and be the first indication of an underlying connective tissue disease. The spectrum of thoracic disease related to rheumatoid arthritis is reviewed

2000-01-01

We report a case of rheumatoid nodule of the right knee in a 55-year-old woman which on the basis of MR images was misdiagnosed as soft tissue sarcoma. Reumatoid nodules occur in up to 20% of adult patients with rheumatoid arthritis and most patients with rheumatoid nodules are rheumatoid factor positive. The nodules are most commonly located between the skin and an underlying bony prominence. In this case, the patient had a history of rheumatoid arthritis and a soft tissue mass was present in the lateral aspect of the right knee. T1-weighted images revealed a mass of similar signal intensity to that of muscle, and on T2-weighted images, a central portion of high signal intensity was noted. Enhanced T1-weighted images demonstrated peripheral rim enhancement. The mass extended to subcutaneous tissue, with penetration of lateral patellar retinaculum. Excisional biopsy was performed, and the pathologic diagnosis was rheumatoid nodule. Although its radiologic findings are non-specific, rheumatoid nodule should -in appropriate clinical setting- be included in the differential diagnosis of a predominantly solid or centrally necrotic periarticular soft tissue.

Objective: To study the changes of serum IL-2, SIL-2R and TNF-α levels after treatment in 39 patients with rheumatoid arthritis. Methods: Serum IL-2, TNF-α (with RIA) and SIL-2R (with ELISA) levels were measured in 39 patients with rheumatoid arthritis. Both before and one year after treatment as well as in 35 controls. Results: Before treatment in the patients the serum IL-2 levels were significantly lower and serum SIL-2R and TNF-α levels, were significantly higher than those in the controls (P<0.01), one year after treatment, the patients without recurrence (n=31) had their serum IL-2, SIL-2R and TNF-α levels returned to normal, but in patients with recurrences (n=8) the levels were about the same as those before treatment. Conclusion: Serum IL-2, SIL-2R and TNF-α lends were closely related to the diseases process and could be of prognostic value. (authors)

Paulina Szady

2017-04-01

Full Text Available Objectives : Rheumatoid arthritis (RA is a systemic disease of connective tissue characterised by chronic course with periods of exacerbation and remission. Even in the early stages of the disease patients report the occurrence of fatigue and sleep disorders. Reduced sleep quality and chronic fatigue are common among patients with rheumatoid arthritis. The aim of the research was to evaluate the severity of fatigue and sleep quality assessment among patients hospitalised with rheumatoid arthritis and to determine the relation between the level of symptoms of fatigue and sleep quality and variables such as: age, gender, disease duration, marital status, applied pharmacological treatment, and pain intensity. Materials and methods : The study involved 38 patients (12 men and 26 women hospitalised in the Rheumatologic Ward of the Orthopaedics and Rehabilitation Hospital of the University of Medical Sciences. The average age of the entire group was 56.26 years. Fatigue was evaluated with use of Polish version of Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F, while in order to evaluate sleep quality within the examined group of patients the Pittsburgh Sleep Quality Index (PSQI was used. Results : Patients with rheumatoid arthritis in the analysed group have lower sleep quality, and within subjects with such a diagnosis the fatigue is present. The relation was found between fatigue and such variables as: age, illness duration, marital status, applied pharmacological treatment, and severity of pain. Sleep quality within patients with RA is correlated by such variables as: age, gender, applied pharmaceutical treatment, and severity of pain. It was identified that patients with lower sleep quality experience increased levels of fatigue. Conclusions : There is a need to clarify which factors determine the level of fatigue and sleep quality in patients suffering from RA in future population-based research and to indicate to doctors

There are few studies that have demonstrated the usefulness of prognostic factors in patients with RA using only variables commonly recorded in the clinical records at the beginning of the disease. The aim of our study was to elaborate a simple questionnaire (PPS: Poor Prognosis Score) to evaluate risk factors at the beginning of the illness classifying it in a mild, moderate or severe. We want to know if this simple questionnaire correlates with known variables of worst outcome such as incapacity, mortality, utilization of health services and surgery. Prognostic factors that have shown an association with the worse outcome of RA in different studies were revised. According to literature and published relative risks (RR) of associations, these can be classified as mild (RR 2.0 and 3.0). In accordance with the levels of association, scores were given to the risk factors being 1 for those prognostic factors with mild association, 2 for those with moderate association, and 3 for those strongly associated with a poor prognosis. The PPS was created with the scores assigned. We excluded from the questionnaire variables not use ID a routine practice in our country such as HLA or although available of high cost for our country as the anti-citrulline antibodies. The chosen variables for the questionnaire were: Mild association: (1 point) age, sex, menopause, smoking, incomplete high school, low socioeconomic status, and depression. Moderate association: (2 points) ESR more than 40, C- Reactive protein 6 mg/dl, knee, elbows and, hands inflammation, and duration of RA more than 6 months without a DMARd treatment. Strong association: (3 points) Rheumatoid factor, presence of hand X- ray hand joints more than 20 joints affected at the beginning of disease, HAQ more than 1, and presence of extraarticular manifestations. Patients were classified in mild RA if the score were less than 10 points, moderate RA between 11 and 20 points and severe RA if the score was more than 20

Ghrelin is a gastric hormone that posses multiple functions, including induction of growth hormone release, regulation of proinflammatory cytokines and control of food intake and energy homeostasis. A few reports on serum ghrelin level in chronic inflammatory states revealed contradictory results. The study was undertaken to determine ghrelin in patients with rheumatoid arthritis receiving infliximab, a TNF-α blocking agent. Serum ghrelin was determined in 18 female rheumatoid patients before the treatment with infliximab, 1 week after the first infusion and after 53 weeks of medication and compared with 15 age-matched healthy women. Serum ghrelin level was shown to be increased in the patients. A decrease in serum ghrelin level was found after the first infusion of infliximab and similarly decreased ghrelin level but still higher than in the control was shown in the 53rd week of medication. The obtained results suggest that ghrelin level is related to inflammation, and its serum level in patients with severe rheumatoid arthritis behaves similarly to acute-phase reactants.

The relevance of the problem of rheumatoid arthritis arises from the influence of such factors as its prevalence rate, unpredictability, tendency towards the transition to the chronic form, severe pain syndrome, high levels of disability, and long-term loss of working ability, as well as the accompanying psycho-emotional disorders. The present reviews article was designed to analyze the premorbid personality characteristics, the specifics features of mental health, and the response to the disease in the patients presenting with rheumatoid arthritis. Special emphasis is placed on the discusses of the relationship between the intensity of the pain syndrome and psycho-emotional disorders. The factors responsible for the development of the depressive states associated with rheumatoid arthritis are distinguished; they are shown to be related to both pathogenesis and the clinical symptoms of the underlying pathology as well as the general course of the disease and the specific features of the patients' psychological condition. The most extensively applied psychodiagnostics techniques are described, and the commonest psychotherapeutic approaches to the combined therapy and rehabilitation of the patients presenting with rheumatoid arthritis are overviewed.

2013-09-01

The study was conducted in order to investigate the effect of disease-related variables such as socio-demographic characteristics, disease complaints and use of necrosis factor (anti-TNF) on the body image and self-esteem in patients with rheumatoid arthritis. The data was collected by an Introductory Information Form, Body Image Scale (PfP) BIS and the Coopersmith Self-Esteem Inventory (SEI) in 120 patients with rheumatoid arthritis and in 120 healthy controls. One-way analysis of variance, Tukey HDS analysis, t-test, Kruskal-Wallis test, the Mann-Whitney U test, and Pearson's and Spearman's correlation coefficients were used to compare the data. 60% of the control group were in the 20-44 year-age group, 75% were women and 30.8% had a bachelor's degree or above, while 60% of patient group were in the 20-44 year-age group, 71.7% were women and 36.7% had a bachelor's degree or higher education level. We observed that the body satisfaction and self-esteem levels were higher in the 20-44 age group, in those with a bachelor's degree or higher education and in the patients who had no additional disease and who did not use anti-TNF. The body satisfaction and self-esteem levels were lower in those who had been receiving treatment for longer than 5 years, who had changes in hands and body, who had gait disturbance and who had changes in family and working life. The assessment of the psychosocial needs with a holistic approach and training programs for body image and self-esteem would be advisable for patients with rheumatoid arthritis who are aged 45-59 years, who have low self-esteem, who have additional diseases, who use anti-TNF, who have changes in hands and body and who have primary-school education.

Tyrosine kinases in rheumatoid arthritis

Directory of Open Access Journals (Sweden)

Kobayashi Akiko

2011-08-01

Full Text Available Abstract Rheumatoid arthritis (RA is an inflammatory, polyarticular joint disease. A number of cellular responses are involved in the pathogenesis of rheumatoid arthritis, including activation of inflammatory cells and cytokine expression. The cellular responses involved in each of these processes depends on the specific signaling pathways that are activated; many of which include protein tyrosine kinases. These pathways include the mitogen-activated protein kinase pathway, Janus kinases/signal transducers and activators transcription pathway, spleen tyrosine kinase signaling, and the nuclear factor κ-light-chain-enhancer of activated B cells pathway. Many drugs are in development to target tyrosine kinases for the treatment of RA. Based on the number of recently published studies, this manuscript reviews the role of tyrosine kinases in the pathogenesis of RA and the potential role of kinase inhibitors as new therapeutic strategies of RA.

Periodontitis increases rheumatic factor serum levels and citrullinated proteins in gingival tissues and alter cytokine balance in arthritic rats.

Directory of Open Access Journals (Sweden)

Mônica G Corrêa

Full Text Available This study investigated some immunological features by experimental periodontitis (EP and rheumatoid arthritis (RA disease interact in destructive processes in arthritic rats. Rats were assigned to the following groups: EP +RA; RA; EP; and Negative Control. RA was induced by immunizations with type-II collagen and a local immunization with Complete Freund's adjuvant in the paw. Periodontitis was induced by ligating the right first molars. The serum level of rheumatoid factor (RF and anti-citrullinated protein antibody (ACCPA were measured before the induction of EP (T1 and at 28 days after (T2 by ELISA assay. ACCPA levels were also measured in the gingival tissue at T2. The specimens were processed for morphometric analysis of bone loss, and the gingival tissue surrounding the first molar was collected for the quantification of interleukin IL-1β, IL-4, IL-6, IL-17 and TNF-α using a Luminex/MAGpix assay. Paw edema was analyzed using a plethysmometer. Periodontitis increased the RF and ACCPA levels in the serum and in the gingival tissue, respectively. Besides, the level of paw swelling was increased by EP and remained in progress until the end of the experiment, when EP was associated with RA. Greater values of IL-17 were observed only when RA was present, in spite of PE. It can be concluded that periodontitis increases rheumatic factor serum levels and citrullinated proteins level in gingival tissues and alter cytokine balance in arthritic rats; at the same time, arthritis increases periodontal destruction, confirming the bidirectional interaction between diseases.

To evaluate the Bristol Rheumatoid Arthritis Fatigue Multidimensional Questionnaire (BRAF-MDQ), the revised Bristol Rheumatoid Arthritis Numerical Rating Scales (BRAF-NRS V2) and the Rheumatoid Arthritis Impact of Disease (RAID) scale in six countries. We surveyed RA patients in France, Germany, The Netherlands, Spain, Sweden and the UK, including the HAQ, 36-item Short Form Health Survey (SF-36) and potential revisions of the BRAF-NRS coping and Spanish RAID coping items. Factor structure and internal consistency were examined by factor analysis and Cronbach's α and construct validity by Spearman's correlation. A total of 1276 patients participated (76% female, 25% with a disease duration <5 years, median HAQ 1.0). The original BRAF-MDQ four-factor structure and RAID single-factor structure were confirmed in every country with ⩾66% of variation in items explained by each factor and all item factor loadings of 0.71-0.98. Internal consistency for the BRAF-MDQ total and subscales was a Cronbach's α of 0.75-0.96 and for RAID, 0.93-0.96. Fatigue construct validity was shown for the BRAF-MDQ and BRAF-NRS severity and effect scales, correlated internally with SF-36 vitality and with RAID fatigue (r = 0.63-0.93). Broader construct validity for the BRAFs and RAID was shown by correlation with each other, HAQ and SF-36 domains (r = 0.46-0.82), with similar patterns in individual countries. The revised BRAF-NRS V2 Coping item had stronger validity than the original in all analyses. The revised Spanish RAID coping item performed as well as the original. Across six European countries, the BRAF-MDQ identifies the same four aspects of fatigue, and along with the RAID, shows strong factor structure and internal consistency and moderate-good construct validity. The revised BRAF-NRS V2 shows improved construct validity and replaces the original. © The Author 2017. Published by Oxford University Press on behalf of the British Society for Rheumatology.

The main cause of death in rheumatoid arthritis (RA) is cardiovascular events. We evaluated the relationship of anticyclic citrullinated peptide (anti-CCP) antibody levels with increased carotid intima-media thickness (cIMT) in RA patients. Methods. Forty-five anti-CCP positive and 37 anti-CCP negative RA patients, and 62 healthy controls (HC) were studied. All groups were assessed for atherogenic index of plasma (AIP) and cIMT. Anti-CCP, C-reactive protein (CRP), and levels of tumor necrosis factor alpha (TNFα) and interleukin-6 (IL-6) were measured by enzyme-linked immunosorbent assay (ELISA). Results. The anti-CCP positive RA patients showed increased cIMT compared to HC and anti-CCP negative (P < 0.001). Anti-CCP positive versus anti-CCP negative RA patients, had increased AIP, TNFα and IL-6 (P < 0.01), and lower levels of high density lipoprotein cholesterol (HDL-c) (P = 0.02). The cIMT correlated with levels of anti-CCP (r = 0.513, P = 0.001), CRP (r = 0.799, P < 0.001), TNFα (r = 0.642, P = 0.001), and IL-6 (r = 0.751, P < 0.001). In multiple regression analysis, cIMT was associated with CRP (P < 0.001) and anti-CCP levels (P = 0.03). Conclusions. Levels of anti-CCP and CRP are associated with increased cIMT and cardiovascular risk supporting a clinical role of the measurement of cIMT in RA in predicting and preventing cardiovascular events.

A Personalized Approach to Biological Therapy Using Prediction of Clinical Response Based on MRP8/14 Serum Complex Levels in Rheumatoid Arthritis Patients.

Directory of Open Access Journals (Sweden)

S C Nair

Full Text Available Measurement of MRP8/14 serum levels has shown potential in predicting clinical response to different biological agents in rheumatoid arthritis (RA. We aimed to develop a treatment algorithm based on a prediction score using MRP8/14 measurements and clinical parameters predictive for response to different biological agents.Baseline serum levels of MRP8/14 were measured in 170 patients starting treatment with infliximab, adalimumab or rituximab. We used logistic regression analysis to develop a predictive score for clinical response at 16 weeks. MRP8/14 levels along with clinical variables at baseline were investigated. We also investigated how the predictive effect of MRP8/14 was modified by drug type. A treatment algorithm was developed based on categorizing the expected response per drug type as high, intermediate or low for each patient and optimal treatment was defined. Finally, we present the utility of using this treatment algorithm in clinical practice.The probability of response increased with higher baseline MRP8/14 complex levels (OR = 1.39, differentially between the TNF-blockers and rituximab (OR of interaction term = 0.78, and also increased with higher DAS28 at baseline (OR = 1.28. Rheumatoid factor positivity, functional disability (a higher HAQ, and previous use of a TNF-inhibitor decreased the probability of response. Based on the treatment algorithm 80 patients would have been recommended for anti-TNF treatment, 8 for rituximab, 13 for another biological treatment (other than TNFi or rituximab and for 69 no recommendation was made. The predicted response rates matched the observed response in the cohort well. On group level the predicted response based on the algorithm resulted in a modest 10% higher response rate in our cohort with much higher differences in response probability in individual patients treated contrary to treatment recommendation.Prediction of response using MRP8/14 levels along with clinical predictors has

The expression of the proinflammatory cytokine leukemia inhibitory factor (LIF) has been reported in the cartilage and synovium of rheumatoid arthritis (RA) patients. Here, we show that high levels of LIF were constitutively produced by cultures of synovium pieces. Low levels of LIF were produced spontaneously by isolated synoviocytes, but interleukin (IL)-1 beta caused a fourfold enhancement of this secretion. The anti-inflammatory cytokine IL-4 reduced the production of LIF by synovium pieces by 75%, as observed earlier with IL-6, IL-1 beta and tumor necrosis factor (TNF)-alpha. IL-4 had a direct effect since it inhibited LIF production by unstimulated and IL-1 beta- or TNF-alpha-stimulated synoviocytes. Conversely, IL-4 enhanced the production of IL-6, which shares with LIF biological activities and receptor components. The inhibitory effect of IL-4 was dose dependent and was reversed using a blocking anti-IL-4 receptor antibody. Similar inhibitory action of IL-4 on LIF production was observed on synovium pieces from patients with osteoarthritis and on normal synoviocytes. IL-10, another anti-inflammatory cytokine acting on monocytes, had no effect on LIF production by either synovium pieces or isolated synoviocytes. Thus, the production of LIF by synovium tissue was inhibited by IL-4 through both a direct effect on synoviocytes and an indirect effect by inhibition of the production of LIF-inducing cytokines.

To determine the presentation patterns, biologically vulnerable patient groups and treatment strategies of rheumatoid arthritis. The retrospective study was conducted at the Rheumatology Clinic of Liaquat National Hospital and Medical College, Karachi, and comprised data of rheumatology patients who presented between September 2006 and September 2012. After screening all the files, rheumatoid arthritis cases were identified. Data collection was done using a questionnaire that included patient demographics, co-morbidities, clinical manifestations and drug therapy. SPSS 13 was used for statistical analysis. Of the 2300 files screened, 500(21.7%) related to patients of rheumatoid arthritis. The mean age at presentation of these 500 patients was 41±15 years. There were 367(73.4%) women and they presented at an earlier age compared to men (p<0.024). Erosions were present in 198(40%) patients on X-rays and 22(4.4%) had joint deformities. Seropositive rheumatoid arthritis was associated with higher erythrocyte sedimentation rate levels (p<0.014), but did not differ from seronegative rheumatoid arthritis in terms of Disease Activity Score-28 levels (p<0.21). The skewed gender distribution was likely an effect of rheumatoid arthritis biology rather than due to issues of healthcare accessibility. Seronegative RA is likely to present late though it is as destructive as the seropositive disease.

A 59-year-old patient, with a history of rheumatoid arthritis, on methotrexate 10 mg PO qwk and IV abatacept 750 mg/month, presented with photosensitivity, foreign body sensation, pain, redness, and blurry vision of her right eye (RE. Visual acuity of the RE was 20/200 and 20/20 of the left eye (LE. The slit lamp examination of the RE revealed dryness, 2+ injection of the conjunctiva, and pericentral ulceration of the cornea with 20–30% stromal thinning, pannus, and diffuse punctate epithelial erosions. The anterior chamber appeared normal. Laboratory values revealed elevated levels of rheumatoid factor, anticyclic citrullinated peptide antibodies, and C-reactive protein. The patient was switched to tofacitinib citrate 5 mg PO b.i.d, underwent corneal gluing, and was given prednisone acetate 1% gt TID, polytrim gt TID, neomycin-polymyxin-dexameth gt QD, FreshKote lubricant 1.8% gt QID, moxifloxacin 0.5% gt QID, and preservative free artificial tears Q1H. Within one week, laboratory values normalized, symptoms diminished, and the cornea reepithelialized. Conclusion. RA can present with ulcerative keratitis. Tofacitinib citrate, steroids, and corneal gluing were found to halt the progression of keratolysis and promote reepithelialization.

Iatrogenic T-Cell Lymphoma with Associated Hemophagocytic Lymphohistiocyotsis in a Patient with Long-Standing Rheumatoid Arthritis

Directory of Open Access Journals (Sweden)

2018-01-01

Full Text Available Patients with rheumatoid arthritis are at increased risk of hematological malignancies, especially when exposed to immunosuppressive therapy. The mechanisms of lymphomagenesis remain poorly understood but factors implicated include high disease activity, exposure to antitumoral necrosis factor medications, and Epstein–Barr virus infection. Lymphoid malignancies of T-cell origin are uncommon in patients with rheumatoid arthirits. Clinical presentation with associated hemophagocytic lymphohistiocyotsis is rare and confers a poor prognosis. This case report illustrates a case of a patient with long-standing rheumatoid arthritis and an iatrogenic peripheral T-cell lymphoma with secondary hemophagocytic lymphohistiocytosis who achieved a complete response after intensive chemotherapy.

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). 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. 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. 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.

Tumor necrosis factor (TNF)-α inhibitor has been shown to affect the periodontal condition of patients with rheumatoid arthritis (RA). The aim of the present study is to assess the effect of a fully humanized anti-TNF-α monoclonal antibody, adalimumab (ADA), on the periodontal condition of patients with RA and to compare serum protein profiles before and after ADA therapy. The study participants consisted of 20 patients with RA treated with ADA. Clinical periodontal and rheumatologic parameters and serum cytokine levels were evaluated at baseline and 3 months later. Serum protein spot volume was examined with two-dimensional sodium dodecyl sulfate polyacrylamide gel electrophoresis. Proteins with significant difference in abundance before and after ADA therapy were found and identified using mass spectrometry and protein databases. The patients showed a significant decrease in gingival index (P = 0.002), bleeding on probing (P = 0.003), probing depth (P = 0.002), disease activity score including 28 joints using C-reactive protein (P protein spots obtained, nine spots were significantly decreased in abundance at reassessment, corresponding to complement factor H, phospholipase D, serum amyloid A, complement component 4, and α-1-acid glycoprotein (P periodontal condition of patients with RA, which might be related to differences in serum protein profiles before and after ADA therapy.

To identify risk factors for large joint (LJS) versus small joint surgery (SJS) in rheumatoid arthritis (RA) and evaluate trends in surgery rates over time. A retrospective medical record review was performed of all orthopedic surgeries following first fulfillment of 1987 ACR criteria for adult-onset RA among residents of Olmsted County, Minnesota, USA in 1980-2013. Risk factors were examined using Cox models adjusted for age, sex and calendar year of RA incidence. Trends in incidence of joint surgeries were examined using Poisson regression models. A total of 1077 patients with RA (mean age 56 years, 69% female, 66% seropositive) were followed for a median of 10.7 years during which 112 (90 women) underwent at least one SJS and 204 (141 women) underwent at least one LJS. Risk factors included advanced age, rheumatoid factor and anti-CCP antibody positivity for both SJS and LJS, and BMI≥30 kg/m 2 for LJS. Risk factors for SJS and LJS at any time during follow-up included the presence of radiographic erosions, large joint swelling, and methotrexate use. SJS rates decreased by calendar year of incidence (hazard ratio 0.53; p=0.001), with significant decline in SJS after 1995. The cumulative incidence of SJS was higher in women than men (p=0.008). In recent years, there has been a significant decline in rates of SJS but not LJS in patients with RA. The incidence of SJS is higher among women. Traditional RA risk factors are strong predictors for SJS and LJS. Increasing age and obesity are predictive of LJS. This article is protected by copyright. All rights reserved.

Rheumatoid arthritis is the most common systematic autoimmune disease and its etiology is believed to have both strong genetic and environmental components. We demonstrate the utility of including genetic and clinical phenotypes as covariates within a linkage analysis framework to search for rheumatoid arthritis susceptibility loci. The raw genotypes of 1302 affected relative pairs were combined from four large family-based samples (North American Rheumatoid Arthritis Consortium, United Kingdom, European Consortium on Rheumatoid Arthritis Families, and Canada). The familiality of the clinical phenotypes was assessed. The affected relative pairs were subjected to autosomal multipoint affected relative-pair linkage analysis. Covariates were included in the linkage analysis to take account of heterogeneity within the sample. Evidence of familiality was observed with age at onset (p << 0.001) and rheumatoid factor (RF) IgM (p << 0.001), but not definite erosions (p = 0.21). Genome-wide significant evidence for linkage was observed on chromosome 6. Genome-wide suggestive evidence for linkage was observed on chromosomes 13 and 20 when conditioning on age at onset, chromosome 15 conditional on gender, and chromosome 19 conditional on RF IgM after allowing for multiple testing of covariates.

Long since it have been suggested that a subpopulation of patients with rheumatoid arthritis (RA), diagnosed with negative rheumatoid factor (RF) tests, represents a clinical entity quite distinct from that of seropositive rheumatoid arthritis. The aim of the study was to establish a scientific comparative analysis between RA seronegative and seropositive, regarding course and prognoses of the disease. Two hundred fifty patients with rheumatoid arthritis according to the (American College of Rheumatology) criteria were retrospectively studied by analysis the course and prognoses of disease. All examinees were between 25-60 years of age (Xb=49.9, SD=10.3) with disease duration between 1-27 years (Xbox=6.41, SD=6.47). Course of the disease with "remissions and exacerbations", progressive continual course and bad prognoses, were more presented in seropositive group ofpatients. Partial remission was more common in seronegative patients but according to serostatus and gender has not shown statistically significant difference. Duration of the disease was a specific prognostic sign for both subsets [(r=0.32, p0.05) seronegative, (r=0.18, p<0.05) seropositive]. Seropositive and seronegative RA distinguish in course and prognostic feature, but not enough to differentiate them in two different forms of the disease. Regarding the sero-status, differences within sex, with some exceptions, are not relevant.

A solid-phase radioimmunoassay capable of detecting nanogram quantities of human IgM rheumatoid factor using a monoclonal anti-..mu..-chain antibody is described. Human IgG did not interfere with the detection of IgM RF by this method. The small nonspecific binding of nonRF IgM to the human IgG coated tubes utilized in the assay must be corrected for by assaying samples in parallel bovine serum albumin coated control tubes only in cases of deviation of IgM from normal range. 69 coded and randomly arranged sera from patients with rheumatoid arthritis (RA), nonrheumatic joint diseases and healthy adult control subjects were investigated by this method, agglutination techniques as well as RIPEGA. A good correlation between solid-phase radioimmunoassay and agglutination techniques was found. Patients with seropositive RA had significantly higher concentrations of IgM RF than seronegative RA patients or control subjects.

Indirect costs of rheumatoid arthritis

Directory of Open Access Journals (Sweden)

Filip Raciborski

Full Text Available It is estimated that in Poland about 400,000 persons in general suffer from inflammatory joint diseases, including rheumatoid arthritis (RA. Epidemiological surveys documenting the frequency and disturbance of musculoskeletal disorders in the Polish population are few in number. Most of the estimations are based on epidemiological data from other countries (prevalence of 0.5–1%. According to the data of the National Health Fund in Poland 135,000–157,000 persons in total are treated because of rheumatoid arthritis per year [ICD10 (International Statistical Classification of Diseases and Related Health Problems: M05, M06]. In the case of this group of diseases indirect costs significantly outweigh the direct costs. Indirect costs increase together with activity level of the disease. The cost analysis of productivity loss of RA patients indicates that sickness absenteeism and informal care are the most burdensome. At the national level it amounts in total from 1.2 billion to 2.8 billion PLN per year, depending on the method of analysis. These costs could be significantly reduced through early diagnosis and introduction of effective treatment.

The aim of the present study was to perform a screening for rheumatoid factor (RF) and anti-nuclear antibody in Kaingang, Guarani and Mestizos individuals from Mangueirinha Reservation, State of Paraná, Brazil, and associate it with demographic and clinical data. Serum samples from 321 aborigines (125 male and 196 female; 4-86 years old) and 180 non-Indians healthy individuals were analysed (62 male and 118 female; 2-81 years old). Antinuclear antibody (ANA) was tested by indirect immunofluorescence, and RF by agglutination in latex and turbidimetry. RF was higher in Kaingang when compared to Guarani (P = 0.009), Mestizos (P = 0.061) and non-Indians (P = 0.010). A significant increase of RF was observed in Kaingang women versus Kaingang men (P = 0.002) and, among the women, in Kaingang when compared to Mestizos and Guarani (P rheumatoid arthritis in two Kaingang Indians. Other two individuals (RF positive) will be under medical observation, as well as two Mestizos. The differences observed among the investigated groups, suggest the influence of genetic and hormonal factors in the development of auto antibodies in these populations.

Rheumatoid arthritis (RA) is an autoimmune disease characterized by synovial hyperplasia and chronic inflammation, which lead to the progressive destruction of cartilage and bone in the joints. Numerous studies have reported that administrations of various types of MSCs improve arthritis symptoms in animal models, by paracrine mechanisms. However, the therapeutic effects of the secreted factors alone, without the cell graft, have been uncertain. Here, we show that a single intravenous administration of serum-free conditioned medium (CM) from human deciduous dental pulp stem cells (SHED-CM) into anti-collagen type II antibody-induced arthritis (CAIA), a mouse model of rheumatoid arthritis (RA), markedly improved the arthritis symptoms and joint destruction. The therapeutic efficacy of SHED-CM was associated with an induction of anti-inflammatory M2 macrophages in the CAIA joints and the abrogation of RANKL expression. SHED-CM specifically depleted of an M2 macrophage inducer, the secreted ectodomain of sialic acid-binding Ig-like lectin-9 (ED-Siglec-9), exhibited a reduced ability to induce M2-related gene expression and attenuate CAIA. SHED-CM also inhibited the RANKL-induced osteoclastogenesis in vitro. Collectively, our findings suggest that SHED-CM provides multifaceted therapeutic effects for treating CAIA, including the ED-Siglec-9-dependent induction of M2 macrophage polarization and inhibition of osteoclastogenesis. Thus, SHED-CM may represent a novel anti-inflammatory and reparative therapy for RA. Copyright © 2015 Elsevier Inc. All rights reserved.

2000-05-01

Conflict and conflict resolution in intimate relationships are not only among the most important factors influencing relationship satisfaction but are also seen in association with clinical symptoms. Styles of conflict will be assessed in patients suffering from panic disorder with and without agoraphobia, in alcoholics and in patients suffering from rheumatoid arthritis. 176 patients and healthy controls filled out the Styles of Conflict Inventory and questionnaires concerning severity of clinical symptoms. A cluster analysis revealed 5 types of conflict management. Healthy controls showed predominantely assertive and constructive styles, patients with panic disorder showed high levels of cognitive and/or behavioral aggression. Alcoholics showed high levels of repressed aggression, and patients with rheumatoid arthritis often did not exhibit any aggression during conflict. 5 Clusters of conflict pattern have been identified by cluster analysis. Each patient group showed considerable different patterns of conflict management.

Reinbold, W.D.; Hehne, H.J.; Rau, W.S.; Freiburg Univ.

1983-01-01

Shoulder arthrography in a patient with rheumatoid arthritis is performed to differentiate between a rheumatoid flare and limitation of motion secondary to tear in the rotator cuff. Accurate diagnosis is important because of the therapeutic implications. The arthrographic findings characteristic of rheumatoid involvement of the shoulder joint are nodular filling defects of the joint, the subacromial and subdeltoideal bursa in case of rotator cuff tear, irregular capsular attachment, contracted joint space and visualized lymphatic drainage. A dilatation of the biceps tendon sheath has not been shown. (orig.) [de

Role of transforming growth factor-beta (TGF) beta in the physiopathology of rheumatoid arthritis.

Science.gov (United States)

Gonzalo-Gil, Elena; Galindo-Izquierdo, María

2014-01-01

Transforming growth factor-beta (TGF-β) is a cytokine with pleiotropic functions in hematopoiesis, angiogenesis, cell proliferation, differentiation, migration and apoptosis. Although its role in rheumatoid arthritis is not well defined, TGF-β activation leads to functional immunomodulatory effects according to environmental conditions. The function of TGF-β in the development of arthritis in murine models has been extensively studied with controversial results. Recent findings point to a non-relevant role for TGF-β in a mice model of collagen-induced arthritis. The study of TGF-β on T-cell responses has shown controversial results as an inhibitor or promoter of the inflammatory response. This paper presents a review of the role of TGF-β in animal models of arthritis. Copyright © 2013 Elsevier España, S.L. All rights reserved.

Ana Luiza Naves Pereira

2016-11-01

Full Text Available Objective: To investigate ankle tenosynovitis in rheumatoid arthritis patients, regarding its presence, the kind of tendon involved and the concordance between clinical and ultrasound findings. Methods: Twenty patients with rheumatoid arthritis and pain or swollen ankle joint were evaluated. Tendon involvement was evaluated with ultrasound imaging. The Health Assessment Questionnaire (HAQ was performed for disability evaluation. Age, sex, disease duration, and vocational activity levels were also obtained. The statistical analysis included Fisher’s exact test. The significance level was 0.05. Results: Tenosynovitis was found in 13 of 20 (65.0% patients in 19 joints, in which 6 were bilaterally (46.1% and unilateral in 7 (53.8%. Tibialis posterior tenosynovitis was seen in nine (45.0% patients, Achilles tenosynovitis in seven (35.0%, tibialis anterior tenosynovitis in three (15.0%, and peroneal tenosynovitis in three (15.0% patients. We found concordance between symptomatic ankle and ultrasonographic findings in 92.3% of the patients with tenosynovitis. Association between severe HAQ with tendon involvement was not found (p>0.05. Disease duration was not associated with tenosynovitis. Patients were predominantly older, female, with mean age around 50.8 years. The long disease duration of patients presented a mean of 11.4 years and, most of them, with no vocational activity (65.0%. Conclusions: The results indicate that ankle tenosynovitis is very common in rheumatoid arthritis patients, both unilateral and bilateral. Tibialis posterior was the most common tendon involvement found. Finally, we found concordance between the clinical and ultrasound findings in almost all rheumatoid arthritis patients with ankle tenosynovitis.

Rheumatoid arthritis (RA) is a chronic systemic inflammatory disease affecting educational levels and limited health literacy are contributory factors. Psychological models may assist in explaining medication nonadherence. Increasing patient knowledge of their disease seems sensible. Existing educational interventions appear ineffective at improving medication adherence, probably due to an overemphasis on provision of biomedical information. A novel approach to patient education using musculoskeletal ultrasound is proposed.

In 188 patients followed for 3 to 12 years, the radiologic course of rheumatoid arthritis was assessed in 20 joint groups. A severe course in most joints was related to the presence of rheumatoid factor and to high values of the ESR. Granulocyte-specific antinuclear antibodies were related to a severe course in most joints. The presence of nodules, the Rose-Waaler titre and the presence of organ non-specific antinuclear antibodies were generally unrelated to the course of the disease. (Auth.)

Full Text Available Rheumatoid nodules can be seen in about 30% of patiens with rheumatoid arthritis. They are occasionally localized subcutaneous, but they can rarely seen in visceral organs. Their appearance can be confused with many clinical conditions when they have atypical localizations. To exclude the presence of a malignancy, these lesions should always be investigated. We aimed to discuss a patient with rheumatoid nodule localized in close neighborhood of hyoid bone, presumed as malignancy.

Full Text Available Involvement of the cervical spine is common in rheumatoid arthritis. Clinical presentation can be variable, and symptoms may be due to neck pain or compressive myeloradiculopathy. We discuss the pathology, grading systems, clinical presentation, indications for surgery and surgical management of cervical myelopathy related to rheumatoid arthritis in this paper. We describe our surgical technique and results. We recommend early consultation for surgical management when involvement of the cervical spine is suspected in rheumatoid arthritis. Even patients with advanced cervical myelopathy should be discussed for surgical treatment, since in our experience improvement in function after surgery is common.

Because cytokines such as tumor necrosis factor (TNF-α and interleukin (IL-6 play a major role in the development of RA, their targeting could constitute a reasonable novel therapeutic strategy for treating RA. Indeed, worldwide clinical trials of TNF inhibiting biologic disease modifying antirheumatic drugs (bDMARDs including infliximab, adalimumab, golimumab, certolizumab pegol, and etanercept as well as the humanized anti-human IL-6 receptor antibody, tocilizumab, have demonstrated outstanding clinical efficacy and tolerable safety profiles, resulting in worldwide approval for using these bDMARDs to treat moderate to severe active RA in patients with an inadequate response to synthetic disease modifying antirheumatic drugs (sDMARDs. Although bDMARDs have elicited to a paradigm shift in the treatment of RA due to the prominent efficacy that had not been previously achieved by sDMARDs, a substantial percentage of patients failed primary or secondary responses to bDMARD therapy. Because RA is a heterogeneous disease in which TNF-α and IL-6 play overlapping but distinct pathological roles, further studies are required to determine the best use of TNF inhibitors and tocilizumab in individual RA patients.

Full Text Available The systemic manifestations of rheumatoid arthritis (RA are fairly diverse. They are associated with high disease activity and an increased risk for deaths, primarily from cardiovascular events. Objective: to study the frequency and spectrum of extra-articular manifestations of RA. Subjects and methods. The trial enrolled 119 patients, including 110 women and 19 men (mean age 47.4+4.3 years, with the reliable and valid diagnosis of RA (mean duration 9.4+3.3 years. The patients were divided into 2 groups: 1 78 patients with the extra-articular manifestations of RA (a study group; 2 44 patients without these signs (a comparison group. Clinical, laboratory, instrumental, and morphological studies were made using current diagnostic methods. Results. By and large, the extra-articular manifestations of RA are closely associated with its activity and joint lesion severity. The study group most commonly had anemia (71.4%, rheumatoid nodules (29.4%, generalized amyotrophy (26.9%, lymphadenopathy (26.1%, prolonged fever (24.4%, and rheumatoid vasculitis (18.5%. The development of extra-articular manifestations was associated with the activity and late diagnosis of RA and rheumatoid factor seropositivity.

Ghrelin, an endogenous orexigenic peptide, has anti-inflammatory effects, down-regulates pro-inflammatory cytokines, and its altered levels are reported in various inflammatory diseases. The human preproghrelin (ghrelin/obestatin) gene shows several single nucleotide polymorphisms (SNPs) including Arg51Gln, Leu72Met, Gln90Leu, and A-501C. The aim of this study was to investigate the frequency, and clinical significance, of these four SNPs in a small cohort of Turkish patients with rheumatoid arthritis (RA). The study included 103 patients with RA and 103 healthy controls. In the RA group, disease activity and disease-related damage were assessed using the Disease Activity Score-28 (DAS-28), and the modified Larsen scoring (MLS) methods. In all the participants, genomic DNA was isolated and genotyped by polymerase chain reaction and restriction fragment length polymorphism analysis. The frequencies of ghrelin gene SNPs were 82.5 and 79.6% in the RA and control groups, respectively, and there were no significant differences in terms of genotype distributions and allele frequencies for these four SNPs between the groups. However, the A-501C SNP was found to be associated with early disease onset, and Gln90Leu SNP with less frequent rheumatoid factor positivity, in the RA group. A-501C SNP is associated with earlier onset of RA suggesting that genetic variations in the ghrelin gene may have an impact on RA. Copyright © 2010 Société française de rhumatologie.

Ono, Kumiko; Ohashi, Satoru; Tanaka, Sakae; Matsumoto, Takuya

2013-07-01

In rheumatoid arthritis (RA) , the osteoclast pathway is activated by abnormal immune conditions accompanied by chronic inflammation, resulting in periarticular osteoporosis and local bone destruction around joints. In addition, multiple factors, including reduced physical activity and pharmacotherapies such as steroids, lead to systemic osteoporosis. These conditions cause decreasing bone mineral density and deterioration of bone quality, and expose patients to increased risk of fracture. Understanding the bone structures of RA and evaluating fracture risk are central to the treatment of RA.

The objective of this study was to determine whether radiographic damage is different in British black African patients with rheumatoid arthritis compared to Caucasian patients. Data on demographics, disease- and disability-related variables were obtained from all black African patients and their age-, gender- and disease-duration-matched Caucasian controls. After all features identifying the patients were concealed, X-rays of hands and feet were scored by using the Sharp/van der Heijde method. Data were analysed using Mann-Whitney U test, t test and chi (2) test. Sixty-four patients (32 in each ethnic group) were studied. The median age was 52 years and median disease duration 6 years. Seventy-two percent of patients were female. Black Africans and Caucasians did not differ significantly in rheumatoid factor positivity, disease-modifying anti-rheumatic drugs and biological treatment use. British black African patients had significantly more tender joints and disability. Joint space narrowing was significantly greater in Caucasian patients [48 (27-85) vs 56 (34-107), p = 0.01]. Caucasian patients had more number of erosions (172 vs 220) and higher erosion score; however, the difference in the erosion scores was not statistically significant [2 (0-48) vs 4.5 (0-46), p = 0.17]. Radiographic damage was less severe in black African patients with rheumatoid arthritis compared to their age-, gender- and disease-duration-matched Caucasian controls. A large prospective study is required to confirm the findings of this study and to establish the factors which might be accountable for any differences in the expression of rheumatoid arthritis in this ethnic group.

Full Text Available BACKGROUND Rheumatoid Arthritis (RA is a chronic inflammatory disease of unknown aetiology marked by a symmetric peripheral polyarthritis. It is the most common form of chronic inflammatory arthritis and often results in joint damage and physical disability. The name is based on the term "rheumatic fever", an illness, which includes joint pain and is derived from the Greekword ῥεύμα-rheuma (nom., ῥεύματος-rheumatos (gen. ("flow, current". The suffix oid ("resembling" gives the translation as joint inflammation that resembles rheumatic fever. The first recognised description of rheumatoid arthritis was made in 1800 by Dr. Augustin Jacob Landré-Beauvais (1772-1840 of Paris. Because, it is a systemic disease, RA may result in a variety of extra-articular manifestations including fatigue, subcutaneous nodules, lung involvement, pericarditis, peripheral neuropathy, vasculitis and haematologic abnormalities. MATERIALS AND METHODS Patients who were diagnosed cases of rheumatoid arthritis attending the rheumatology clinic were referred to the Ophthalmology OPD in Government Medical College, Thrissur, for detailed eye examination. RESULTS The study was conducted in 100 patients (88 females and 12 males. Rheumatoid Factor (RF was found to be positive in 60 patients (60%, presence of dry eye did not correlate with rheumatoid positivity (Fishers exact test- the two-tailed P value = 0.4256. Through various tests, we concluded that there was aqueous deficiency in 61% and mucin deficiency in 46% of the patients. Other ocular manifestations present were- scleritis (2%, episcleritis (2% and keratomalacia (2%. CONCLUSION From the present study, we found out that extra-articular involvement of organs in rheumatoid arthritis is significant. The main ocular manifestations in rheumatoid arthritis found in our study were keratoconjunctivitis sicca, episcleritis, scleritis and keratomalacia. Though keratoconjunctivitis sicca was the most common, it did

Rheumatoid arthritis as psychic problem

Full Text Available The article deals with the issue of psychic problems of rheumatoid arthritis patients. Rheumatoid arthritis is a chronic, inflammatory motor system disease with comprehensive impact on the patient's life. The disease is often considered an exclusively physical disease. But such approach is insufficient because the disease is accompanied by motor limitations of different intensities, by pain and by fatigue that cause considerable exhaustion to the patient. The patients often must give up their hobbies and in some cases even their jobs. In most serious cases, even common daily activities including self–servicing actions become an obstacle to the patient. It is therefore logical that the psyche of a patient with such disease is considerably strained. One of the partial goals of the study consisted in mapping the subjectively perceived quality of life of rheumatoid arthritis patients in facet 8, "negative feelings", and in ascertaining whether there is statistically significant relation to facets 1, "pain and discomfort", and 2, "energy and fatigue". Another goal consisted in comparing the subjectively perceived quality of life between men and women with rheumatoid arthritis, as well as between population of rheumatoid arthritis patients and control healthy population.

Autoantibodies have been associated with human pathologies for a long time, particularly with autoimmune diseases (AIDs). Rheumatoid factor (RF) is known since the late 1930s to be associated with rheumatoid arthritis (RA). The discovery of anticitrullinated protein antibodies in the last century has changed this and other posttranslational modifications (PTM) relevant to RA have since been described. Such PTM introduce neoepitopes in proteins that can generate novel autoantibody specificities. The recent recognition of these novel specificities in RA provides a unique opportunity to understand human B-cell development in vivo. In this paper, we will review the three of the main classes of PTMs already associated with RA: citrullination, carbamylation, and oxidation. With the advancement of research methodologies it should be expected that other autoantibodies against PTM proteins could be discovered in patients with autoimmune diseases. Many of such autoantibodies may provide significant biomarker potential. PMID:24782594

16 patients suffering from rheumatoid arthritis and suspected compressive cervical myelopathy were studied with a 0.5 T superconducting magnetic resonance imaging (MRI) scanner. MRI findings were compared with those of plain radiography and myelography. Subluxation was detected equally well by MRI and radiography. MRI was able to detect the presence, level and origin of cord compression. MRI was superior in diagnosing the extent of cord compression. Cord distortion detected by MRI correlated better with clinical evidence of myelopathy than did the radiographically established extent of the subluxation. MRI correctly diagnosed the level and cause of cord compression in six patients who were subsequently operated upon because of progressive neurological signs. These findings suggest that MRI has potential in the diagnosis and management of patients with rheumatoid arthritis suspected of compressive cervical myelopathy. 20 refs.; 4 figs.; 1 table

Limitations of a hemolytic plaque assay for IgG-anti-IgG rheumatoid factor-producing cells.

Science.gov (United States)

Venn, A J; Dresser, D W

1987-09-24

An attempt has been made to develop a hemolytic plaque assay capable of detecting homophile IgG rheumatoid factor (RF)-producing cells. Anti-immunoglobulin allotype-developing reagents were used to distinguish between target and effector IgG. The hemolytic assay has been used to demonstrate an apparently high level of homophile IgM and IgG RF-producing cells in the spleens and lymph nodes of mice stimulated by LPS. However, it appears that a large proportion of the plaques obtained in these assays are due to an artefact resulting from cross-linking of target and effector molecules by the developing reagents. In the case of IgM RF the artefact depends on the presence of a small contamination of the target IgG by IgM, allowing cross-linking of target and effector IgM by the anti-mu-specific developing reagent. With the IgG RF, cross-reactivity of the rabbit anti-Ighb allotype-developing serum for the 'wrong' (Igha) allotype, normally undetectable, becomes sufficient to be biologically relevant when the developing antibody is complexed by being bound to its target (Ighb) allotype. Nevertheless anti-allotype reagents may afford an accurate means of detecting homophile IgG RF producing cells using other assay systems.

Decreasing the daily dose of glucocorticoids improved bone metabolic marker levels in patients with rheumatoid arthritis. However, changes in disease activity did not influence bone metabolism. Bone metabolism might thus remain uncontrolled even if disease activity is under good control. Decreasing glucocorticoid dosage appears important for improving bone metabolism. Patients with rheumatoid arthritis (RA) develop osteoporosis more frequently than healthy individuals. Bone resorption is increased and bone formation is inhibited in patients with RA, and glucocorticoid negatively affects bone metabolism. We aimed to investigate factors influencing bone metabolic markers in patients with RA. We started the 10-year prospective cohort Total Management of Risk Factors in Rheumatoid Arthritis Patients to Lower Morbidity and Mortality (TOMORROW) study in 2010. We compared changes in urinary cross-linked N-telopeptide of type I collagen (uNTx) and serum osteocalcin (OC), as markers of bone resorption and formation, respectively, in 202 RA patients and age- and sex-matched volunteers between 2010 and 2011. We also investigated factors influencing ΔuNTx and ΔOC in the RA group using multivariate analysis. Values of ΔuNTx were significantly lower in patients with RA than in healthy controls (-0.51 vs. 7.41 nmol bone collagen equivalents (BCE)/mmol creatinine (Cr); p = 0.0013), whereas ΔOC values were significantly higher in RA patients (0.94 vs. 0.37 ng/ml; p = 0.0065). Changes in prednisolone dosage correlated negatively with ΔOC (β = -0.229, p = 0.001), whereas changes in disease activity score, bisphosphonate therapy, and period of biologics therapy did not correlate significantly with ΔOC. No significant correlation was seen between ΔuNTx and change in prednisolone dosage. Decreased glucocorticoid dosage improved bone metabolic markers in RA, but disease activity, bisphosphonate therapy, and period of biologics therapy did not influence

Smoking and Rheumatoid Arthritis

Directory of Open Access Journals (Sweden)

Kathleen Chang

2014-12-01

Full Text Available Rheumatoid arthritis (RA is a chronic inflammatory disease caused by both genetic and environmental factors. Smoking has been implicated as one of the most important extrinsic risk factors for its development and severity. Recent developments have shed light on the pathophysiology of RA in smokers, including oxidative stress, inflammation, autoantibody formation and epigenetic changes. The association of smoking and the development of RA have been demonstrated through epidemiologic studies, as well as through in vivo and animal models of RA. With increased use of biological agents in addition to standard disease-modifying antirheumatic drugs (DMARDs, there has been interest in how smoking affects drug response in RA treatment. Recent evidence suggests the response and drug survival in people treated with anti-tumour necrosis factor (anti-TNF therapy is poorer in heavy smokers, and possible immunological mechanisms for this effect are presented in the current paper.

TNFα blockers and infectious risk in rheumatoid arthritis

Directory of Open Access Journals (Sweden)

S. Todesco

2011-06-01

Full Text Available Patients suffering from rheumatoid arthritis have increased risk of infections when compared with general population. The risk depends directly from disease activity and severity. Furthermore, risk increases with aging, immunosuppressive agents and comorbidities such as diabetes, pulmonary and cardiac diseases. In particular corticosteroids, even at low doses, are a major risk factor. Due to disease related risk it is difficult to separate the risk deriving from the use of TNF alpha blockers. Data from clinical trials, meta-analysis and national registers are somewhat contradictory. In patients with rheumatoid arthritis on routine follow-up, treatment with TNF alpha blockers seems to carry an increased risk of infections compared to traditional DMARDs but not associated with increased risk of overall serious infection. Physicians should carefully monitor for signs of infection when using TNF alpha blockers, particularly shortly after treatment initiation.

Rheumatoid arthritis (RA) is a systemic autoimmune disease in whose etiology genetic factors are known to play an important role. Among the genes associated with RA, STAT4 could be an important factor in conducting helper T cells toward the pro-inflammatory Th1 and Th17 lineages. The aim of this study is to determine the association of the STAT4 polymorphism rs7574865 with RA, disease activity, and anti-cyclic citrullinated peptide (CCP) antibody levels in a Mexican population. Genotyping was carried out using the Taqman® system from Applied Biosystems in 140 patients with RA and 150 healthy subjects. Disease activity was evaluated by a rheumatologist using the DAS28 and Spanish-HAQ-DI instruments. Anti-CCP levels were determined by ELISA. Associations of the genotypes of rs7574865 with DAS28, HAQ, and anti-CCP antibody levels with RA were determined. Findings showed that the GT and TT genotypes and the T allele from rs7574865 were all associated as risk factors for RA, independently of their anti-CCP status. An association with moderate-to-high disease activity (DAS28 ≥ 3.2) was also found. Additionally, patients with the GT or TT genotypes showed lower HAQ values than those who carried the GG genotype. No differences in anti-CCP antibody levels or DAS28 and genotypes were found. This work supports the association of the STAT4 rs7574865 polymorphism with RA and disease activity, but not with anti-CCP antibody levels in a Mexican population.

National University of Water and Environmental Engineering   Abstract Background: Rheumatoid arthritis is one of the most common forms of inflammatory diseases of the joints. The disease leads to deformation, then to destruction of the diseased joint and to disability. Physiotherapy is used for the treatment and rehabilitation of rheumatoid arthritis. It is assumed that physiotherapy treatments that promote remission of the disease, improve the quality of patients’ life, create the necessary conditions for comprehensive rehabilitation programs. Objective: Systematic’s review conducting of studies that assess the effect of physiotherapy in the rehabilitation of patients with rheumatoid arthritis. Methods: Theoretical analysis of scientific and methodical literature, methods of analysis, synthesis, generalization. Results: To reduce inflammation in the joints is performed UV of affected joints weak or medium erythermal or middle erythermal doses used UHF therapy. UHF-therapy prescribed to the area of joint in I or II dose, duration 10 min., the course – 5-8 treatments. For patients with minimal activity is added electrophoresis NSAIDs. Electrophoresis aspirin is applied on the affected joints (every day, the course – 10-12 procedures, which favorably affect the course of rheumatoid arthritis. Conclusions: Physical therapy can reduce pain and stiffness in the joints, prevent deformity and restore function, improve independence and quality of life. State of the art is a major incentive to develop new activities in the treatment and rehabilitation of patients with rheumatoid arthritis to improve joint functional activity and their physical health.   Keywords: rheumatoid arthritis, physiotherapy, rehabilitation, hydrotherapy.

Rheumatoid factor (RF) consists of autoantibodies and because of its heterogeneity its determination is not easy. Currently, nephelometry and Elisa method are considered as reference methods. Due to consolidation, many laboratories have fully automated turbidimetric apparatus, and specific nephelemetric systems are not always available. In addition, nephelemetry is more accurate, but time consuming, expensive, and requires a specific device, resulting in a lower efficiency. Turbidimetry could be an attractive alternative. The turbidimetric RF test from Diagam meets the requirements of accuracy and precision for optimal clinical use, with an acceptable measuring range, and could be an alternative in the determination of RF, without the associated cost of a dedicated instrument, making consolidation and saving blood possible.

Full Text Available This cross-sectional study is conducted to determine the prevalence of asymptomatic cervical spine subluxation in rheumatoid arthritis patients by plain radiographs and its relation to demographic and clinical characteristics, disease activity measures and medications. 100 rheumatoid arthritis patients (18 male and 82 female were selected randomly, according to the American college of Rheumatology Criteria, who were under follow up in the rheumatology clinic. A complete history was taken, and physical examination has been done with focus on the cervical spine to determine their demographic data, disease duration, age of disease onset, drug history, swollen and tender joint counts, and ESR, Hb, CRP, RF levels. The disease activity of patients with rheumatoid arthritis was measured using the disease activity score 28. Radiographs of the cervical spine included lateral views taken in flexion, extension, neutral position of the neck and anterioposterior and odontoid projection view. Asymptomatic cervical spine subluxation was found in 17 of the 100 patients (17%. The prevalence of, anterior atlantoaxial subluxation, atlantoaxial impaction and subaxial subluxation was 10(10%, 5(5% and 6(6%, respectively. Posterior subluxation was not detected. The only characteristic that showed meaningful relationship with cervical spine subluxation was CRP (P=0.036. Our results showed that patients with RA, who have cervical spine subluxation cannot be distinguished on the basis of symptoms. Cervical spine involvement is common and may be asymptomatic, indicating routine cervical spine imaging is needed in patients with RA.

Patients with rheumatoid arthritis (RA) have been recognized to experience falls frequently due to functional disabilities. The aim of this study was to prospectively investigate factors influencing falls in patients with RA compared to controls. We compared the frequency of falls in 208 RA patients and 205 age- and sex-matched volunteers for four years and analyzed risk factors for falls in RA patients using multivariate regression analysis. No significant difference in the incidence rate of falls (/person-year) between patients with RA (median [interquartile range]: 0 [0, 0.5]) and controls (0 [0, 0.5]) was evident during four years. Logistic regression analysis identified age, sex, body mass index, history of falls, and lower limb implant at baseline as significant risk factors for falls. The highest quartile of anti-CCP antibody level (>300.6 U/ml) was the strongest predictor for multiple falls (odds ratio, 2.97; 95% confidence interval, 1.12-7.91, p = 0.029) among RA patients. During four years we could not observe the higher incidence rate of falls in RA patients compared to controls in our cohort. Subjects with a higher titer of anti-CCP antibody might be at higher risk of frequent falls among RA patients.

Full Text Available OBJECTIVES: This meta-analysis was conducted to investigate whether the status of rheumatoid factor (RF and anti-cyclic citrullinated peptide (anti-CCP antibody are associated with the clinical response to anti-tumor necrosis factor (TNF alpha treatment in rheumatoid arthritis (RA. METHODS: A systemic literature review was performed using the MEDLINE, SCOPUS, Cochrane Library, ISI Web of Knowledge, and Clinical Trials Register databases, and Hayden's criteria of quality assessment for prognostic studies were used to evaluate all of the studies. The correlation between the RF and anti-CCP antibody status with the treatment effect of anti-TNFα agents was analyzed separately using the Mantel Haenszel method. A fixed-effects model was used when there was no significant heterogeneity; otherwise, a random-effects model was applied. Publication bias was assessed using Egger's linear regression and a funnel plot. RESULTS: A total of 14 studies involving 5561 RA patients meeting the inclusion criteria were included. The overall analysis showed that the pooled relative risk for the predictive effects of the RF and anti-CCP antibody status on patient response to anti-TNFα agents was 0.98 (95% CI: 0.91-1.05, p=0.54 and 0.88 (95% CI: 0.76-1.03, p=0.11, respectively, with I(2 values of 43% (p=0.05 and 67% (p<0.01, respectively. Subgroup analyses of different anti-TNFα treatments (infliximab vs. etanercept vs. adalimumab vs. golimumab, response criteria (DAS28 vs. ACR20 vs. EULAR response, follow-up period (≥ 6 vs. <6 months, and ethnic group did not reveal a significant association for the status of RF and anti-CCP. CONCLUSIONS: Neither the RF nor anti-CCP antibody status in RA patients is associated with a clinical response to anti-TNFα treatment.

Full Text Available We evaluated changes in gene expression of mTOR, p21, caspase-3, ULK1, TNFα, matrix metalloproteinase (MMP-9, and cathepsin K in the whole blood of rheumatoid arthritic (RA patients treated with methotrexate (MTX in relation to their rheumatoid factor status, clinical, immunological, and radiological parameters, and therapeutic response after a 24-month follow-up. The study group consisted of 35 control subjects and 33 RA patients without previous history of MTX treatment. Gene expression was measured using real-time RT-PCR. Decreased disease activity in patients at the end of the study was associated with significant downregulation of TNFα expression. Downregulation of mTOR was observed in seronegative patients, while no significant changes in the expression of p21, ULK1, or caspase-3 were noted in any RA patients at the end of the study. The increase in erosion numbers observed in the seropositive patients at the end of the follow-up was accompanied by upregulation of MMP-9 and cathepsin K, while seronegative patients demonstrated an absence of significant changes in MMP-9 and cathepsin K expression and no increase in the erosion score. Our results suggest that increased expression of MMP-9 and cathepsin K genes in the peripheral blood might indicate higher bone tissue destruction activity in RA patients treated with methotrexate. The clinical study registration number is 0120.0810610.

The clinical significance of previously described immunoglobulin and complement deposition in the superficial dermal vessel walls of patients with rheumatoid arthritis is unknown. In the present study, skin biopsies were obtained from the normal forearm and buttock of 48 unselected patients with rheumatoid arthritis and were examined by direct immunofluorescence (IF) for the presence of immunoglobulin (IgG,A,M) and complement (C3) in the vessel walls. Deposits of C3, IgM or IgG were detected in 10 patients. Five patients had deposits at the forearm sample alone, four patients had deposits at both biopsy sites, while one patient was positive at the buttock alone. Clinical features were similar in patients with and without vessel IF. However, patients with IF were significantly more seropositive with lower levels of complement and raised levels of serum IgA and IgM. There was also an increased level of circulating IgG immune complexes in these patients. Further analysis following exclusion of seronegative patients revealed similar results. This study suggests that the presence of vessel IF identifies a subgroup of patients who have evidence of more severe immunological disturbance.

Methods: The MarketScan Medicaid Multistate Database was used to identify adult RA patients who used etanercept, adalimumab, or infliximab (index agents from 2007 to 2011. The index date was the first claim preceded by 180 days and followed by 360 days of continuous enrollment. Patients with other conditions for which these agents are approved by the US Food and Drug Administration were excluded. “Continuing” patients had one or more pre-index claim for their index biologic, and "new" patients did not. Cost per treated patient was calculated in the 360 day post-index period for each index agent as the total index drug and administration cost to the payer and the costs of switched-to agents divided by the number of patients who received the index agent. Results: A total of 1,085 patients met the study criteria. Forty-eight percent received etanercept (n=521; 37% received adalimumab (n=405; and 15% received infliximab (n=159. Patient characteristics were similar across groups (mean age 47.4 years, 83% female. The annual cost per treated patient was lowest for etanercept ($18,466, followed by adalimumab ($20,983 and infliximab ($26,516. For all agents, annual costs were lower for new patients ($17,996 for etanercept, $18,992 for adalimumab, and $24,756 for infliximab than for continuing patients ($19,004 for etanercept, $24,438 for adalimumab, and $28,127 for infliximab. Conclusion: Etanercept had lower costs per treated patient than adalimumab or infliximab in both new and continuing Medicaid enrollees with RA. Keywords: cost, tumor necrosis factor

Full Text Available INTRODUCTION: Epstein-Barr virus exposure appears to be an environmental trigger for rheumatoid arthritis that interacts with other risk factors. Relationships among anti-cyclic citrullinated peptide antibodies, the shared epitope, and smoking status have been observed in patients with rheumatoid arthritis from different populations. OBJECTIVE: To perform an association analysis of anti-Epstein-Barr nuclear antigen-1 antibodies, anti-cyclic citrullinated peptide antibodies, the shared epitope, and smoking status in Brazilian patients with rheumatoid arthritis. METHODS: In a case-control study, 140 rheumatoid arthritis patients and 143 healthy volunteers who were matched for age, sex, and ethnicity were recruited. Anti-Epstein-Barr nuclear antigen-1 antibodies and anti-cyclic citrullinated peptide antibodies were examined using an enzyme-linked immunosorbent assay, and shared epitope alleles were identified by genotyping. Smoking information was collected from all subjects. A comparative analysis of anti-Epstein-Barr nuclear antigen-1 antibodies, anti-cyclic citrullinated peptide antibodies, the shared epitope, and smoking status was performed in the patient group. Logistic regression analysis models were used to analyze the risk of rheumatoid arthritis. RESULTS: Anti-Epstein-Barr nuclear antigen-1 antibodies were not associated with anti-cyclic citrullinated peptide antibodies, shared epitope alleles, or smoking status. Anti-cyclic citrullinated peptide antibody positivity was significantly higher in smoking patients with shared epitope alleles (OR = 3.82. In a multivariate logistic regression analysis using stepwise selection, only anti-cyclic citrullinated peptide antibodies were found to be independently associated with rheumatoid arthritis (OR = 247.9. CONCLUSION: Anti-Epstein-Barr nuclear antigen-1 antibodies did not increase the risk of rheumatoid arthritis and were not associated with the rheumatoid arthritis risk factors studied. Smoking

Objective: To determine the spectrum of clinical presentation, laboratory parameters and drug therapy in patients with Juvenile Rheumatoid Arthritis (JRA). Study Design: Case series. Place and Duration of Study: The Children's Hospital and The Institute of Child Health, Lahore, from October 2008 to October 2011. Methodology: All patients who fulfilled the American College of Rheumatology criteria for JRA were enrolled. Their clinical features, investigations done and treatment received for JRA were noted. Statistical analysis of data was done on SPSS version 16.0 for obtaining descriptive statistics. Results: Out of 185 patients, 50.3% (n = 93) were females; 54% (n = 100) were between 10 - 15 years of age. Polyarthritis was found in 71.9% (n = 133) followed by oligoarthritis (22.7%, n = 42) and systemic onset disease (5.4%, n = 10). Morning stiffness (78%) and fever (68%) were the most common clinical presentations. All patients with systemic onset disease had fever (n = 10) followed by skin rash, hepatosplenomegaly and lymphadenopathy. Uveitis was found in 2 patients, and both belonged to the oligoarticular group. Rheumatoid factor was found in 10.27% (n = 19) of all patients. All patients were given non-steroidal anti-inflammatory drugs (NSAIDs). Disease modifying agents (methotrexate) were given to 43.8% (n = 81). Steroids were used in 61% (n = 113) of patients either with NSAIDs alone or NSAIDs plus methotrexate. Conclusion: Disease profile of JRA at the study centre showed that polyarthritis is the commonest type. Recognition of subtypes will help in planning the management of these patients. (author)

To describe and understand the meaning of living with persistent rheumatoid arthritis. A considerable number of patients with rheumatoid arthritis live with an ongoing active and symptomatic illness despite access to potent antirheumatic treatment. There is, however, a lack of knowledge about the meaning of living with this severe long-term illness, defined as persistent rheumatoid arthritis. A descriptive design based on a hermeneutic phenomenological method was used. Ten adults with persistent rheumatoid arthritis and at least five years disease duration were interviewed. The interviews were analysed according to van Manen's method. Living with persistent rheumatoid arthritis revealed four overall themes: an existence dominated by painful symptoms and treatment, radical changes and limitations in one's life, a continual struggle to cope with one's life and to master the illness, and a dependency on those who are close by and the world around. The lifeworld was affected to a varying extent and in various ways by the illness but also by the dependence on its treatment and care that was not experienced as sufficiently meeting needs in terms of security, access to and coordination of care as well as team and rehabilitation services. Persistent rheumatoid arthritis and its treatment entail a radical effect on the person's life and quality of life. Current ordinary rheumatology care does not seem to meet the individual needs of the person with persistent rheumatoid arthritis in an optimal way. A greater knowledge about and understanding of the person who lives with persistent rheumatoid arthritis is important for facilitating the development of care and the relief of suffering. A holistic alternative to conventional clinical practice, such as person-centred care, could be tested as an innovative model of care. Our findings might serve as material for educational and counselling purposes for healthcare professionals. © 2016 John Wiley & Sons Ltd.

Intestinal Dysbiosis and Rheumatoid Arthritis: A Link between Gut Microbiota and the Pathogenesis of Rheumatoid Arthritis

2017-01-01

Full Text Available Characterization and understanding of gut microbiota has recently increased representing a wide research field, especially in autoimmune diseases. Gut microbiota is the major source of microbes which might exert beneficial as well as pathogenic effects on human health. Intestinal microbiome’s role as mediator of inflammation has only recently emerged. Microbiota has been observed to differ in subjects with early rheumatoid arthritis compared to controls, and this finding has commanded this study as a possible autoimmune process. Studies with intestinal microbiota have shown that rheumatoid arthritis is characterized by an expansion and/or decrease of bacterial groups as compared to controls. In this review, we present evidence linking intestinal dysbiosis with the autoimmune mechanisms involved in the development of rheumatoid arthritis.

Biologic agents are effective treatments for rheumatoid arthritis but are associated with important risks, including severe infections. Tumor Necrosis Factor (TNF) α inhibitors are known to increase the risk of systemic fungal infections such as disseminated histoplasmosis. Abatacept is a biologic agent with a mechanism different from that of TNFα inhibitors: It suppresses cellular immunity by competing for the costimulatory signal on antigen-presenting cells. The risk of disseminated histoplasmosis for patients on abatacept is not known. We report a case of abatacept-associated disseminated histoplasmosis and review the known infectious complications of abatacept. While the safety of resuming biologic agents following treatment for disseminated histoplasmosis is also not known, abatacept is recommended over TNFα inhibitors for rheumatoid arthritis patients with a prior serious infection. We discuss the evidence supporting this recommendation and discuss alternative treatments for rheumatoid arthritis patients with a history of a serious infection.

Full Text Available Treatment of patients with severe clinical course of juvenile rheumatoid arthritis (JRA is difficult problem. During the last years genetically engineered biological drugs are used equally with traditional immunosuppressive agents in treatment of severe forms of juvenile arthritis. High effectiveness of these drugs can be accompanied with development of unfavorable effects, for example, febrile neutropenia. The article presents results of a study of effectiveness and safety of recombinant human granulocytic colony-stimulating factor — filgrastim (Leucostim — in treatment of granulocytopenia developed during immunosuppressive therapy in 16 patients with JRA. It was shown that administration of filgrastim arrests leucopenia in 100% of patients and granulocytopenia — in 93% of patients in 24 hours after first injection. High effectiveness of drug was combined with good tolerability and safety.Key words: children, treatment, granulocytopenia, filgrastim, juvenile rheumatoid arthritis.(Voprosy sovremennoi pediatrii — Current Pediatrics. – 2010;9(4:94-100

Pertechnetate (sup(99m)TcO 4 - ) joint scintigraphy was performed on 45 patients with rheumatoid arthritis, 3 with nonspecific arthritis and 6 normal subjects. 1) The sites of radioisotopic accumulation were generally in agreement with those of clinical involvement in rheumatoid arthritis. 2) By analysis of build-up curves in the wrist joint, tracer was found to be concentrated more rapidly in rheumatoid arthritis (T 1/2 = 0.67 min.) than in nonspecific arthritis (T 1/2 = 2.66 min.) 3) The degree of radioisotopic accumulation correlated well with the value of CRP and erythrocyte sedimentation rate. It could be cosidered that pertechnetate joint scintigraphy is useful for clinical evaluation of rheumatoid arthritis. (author)

Full Text Available We evaluated the association between anti-cyclic citrullinated peptide antibodies (anti-CCP and anti-mutated citrullinated vimentin antibodies (anti-MCV with the presence of extra-articular (ExRA manifestations in 225 patients with rheumatoid arthritis (RA. Ninety-five patients had ExRA and 130 had no ExRA. There was no association of anti-CCP and anti-MCV levels with the presence of ExRA as total group (P=0.40 and P=0.91, resp.. Making an analysis of individual manifestations, rheumatoid nodules were associated with positivity for rheumatoid factor (RF; (P=0.01, anti-CCP (P=0.048, and anti-MCV (P=0.02. Instead, RF, anti-CCP, or anti-MCV were not associated with SS, chronic anemia, or peripheral neuropathy. Levels of anti-CCP correlated with the score of the Health Assessment Questionnaire-Disability Index (HAQ-Di (r=0.154, P=0.03, erythrocyte sedimentation rate (ESR; (r=0.155, P=0.03, and RF (P=0.254, P<0.001, whereas anti-MCV titres only correlated with RF (r=0.169, P=0.02. On adjusted analysis, ExRA was associated with longer age (P=0.015, longer disease duration (P=0.007, higher DAS-28 score (P=0.002, and higher HAQ-DI score (P=0.007, but serum levels of anti-CCP and anti-MCV were not associated. These findings show the need to strengthen the evaluation of the pathogenic mechanisms implied in each specific ExRA manifestation.

The purpose of this study was to explore the relationship between disability status and duration of morning stiffness in hands with regard to age, level of education, and gender in patients with rheumatoid arthritis (RA). Also, the authors wanted to investigate this relationship with regard to the presence of rheumatoid factor, i.e., the serological status. A retrospective study was conducted in 250 patients with the classic form of RA (186 females, s64 males, mean age Xb = 49.96 y ears, range 25-60 years, disease duration 1-27 years, Xb = 6.41) previously diagnosed with RA according to the ACR (American College of Rheumatology 1987 criteria). All patients were in Steinbrocker functional classes II and III. The probability level was expressed by p 0.05) seronegative, (r = 0.12, y = 0.00x + 2.30, p > 0.05) seropositive]. High positive values were obtained for the linear correlation coefficient between duration of the disease and functional class (p < 0.01). Also, high values were obtained regarding the coefficient of correlation between age and functional class [(r = 0.29, p < 0.01) seronegative, (r = 0.47, p < 0.01) seropositive]. Uneducated patients were significantly more represented in functional class III [ 23 (50%) seronegative, 19 (42.2%) seropositive] than in functional class II [16 (20.3%) seronegative, 22 (27.5%) seropositive]. In conclusion, in this study of patients with rheumatoid arthritis, increased duration of morning stiffness was associated with functional disability. Functional disability increased with the duration of the disease, depended on age and educational level, and was more pronounced in older age, regardless of RA serological status. With regard to serological status and sex, the differences were non-significant.

The Th17, Th1 and dual Th17/Th1 cells are important players in rheumatoid arthritis (RA) disease. To assess their roles, the frequency and impact of these cells were investigated in patients with different disease activity. In 14 new cases and 41 established RA patients in comparison with 22 healthy controls, the percentages of Th17, Th1 and dual Th17/Th1 cells were determined by flow-cytometry and their correlations were investigated with disease activity score (DAS28). Moreover, serum levels of IL-6 and IL-17 as inducer and functional cytokines for Th17 were investigated. Finally, serum levels of anti citrullinated protein antibody (ACPA) and rheumatoid factor (RF) were assessed. Percentage of Th17 cells in RA patients were increased in comparison with healthy controls (pTh1 cells in RA patients were less than healthy group (pTh17/Th1 cell only in new cases of RA were more than healthy control groups (pTh1/Th17 ratio in RA patients is statistically different with healthy control group (pTh1/Th17 ratio in RA patient suggested a new paradigm in the field of autoimmune disease and indicated that imbalance or plasticity between these subsets can be important in progress, diagnosis and therapy of RA disease.

Generalized bone loss can be considered an extra-articular manifestation of rheumatoid arthritis (RA) that may lead to the occurrence of fractures, resulting in decreased quality of life and increased healthcare costs. The peptide ghrelin has demonstrated to positively affect osteoblasts in vitro and has anti-inflammatory actions, but the studies that correlate ghrelin plasma levels and RA have contradictory results. We aimed to evaluate the correlation between total ghrelin plasma levels, density of ghrelin-immunoreactive cells in the gastric mucosa, and bone mineral density (BMD) in twenty adult women with established RA with 6 months or more of symptoms (mean age of 52.70±11.40 years). Patients with RA presented higher ghrelin-immunoreactive cells density in gastric mucosa (P=0.008) compared with healthy females. There was a positive relationship between femoral neck BMD and gastric ghrelin cell density (P=0.007). However, these same patients presented a negative correlation between plasma ghrelin levels and total femoral BMD (P=0.03). The present results indicate that ghrelin may be involved in bone metabolism of patients with RA. However, the higher density of ghrelin-producing cells in the gastric mucosa of these patients does not seem to induce a corresponding elevation in the plasma levels of this peptide.

Patients with rheumatoid arthritis (RA) from different ethnic groups present elevated levels of antibodies against Proteus mirabilis. This finding implicates P. mirabilis in the development of RA. The aim of this study was to investigate the importance of P. mirabilis in the etiopathogenesis of RA in Greek RA patients. In this study, 63 patients with RA and 38 healthy controls were included. Class-specific antibodies IgM, IgG, and IgA against three human cross-reactive and non-cross-reactive synthetic peptides from P. mirabilis-hemolysin (HpmB), urease C (UreC), and urease F (UreF)-were performed in all subjects, using the ELISA method. RA patients had elevated levels of IgM, IgG, and IgA antibodies against HpmB and UreC Proteus peptide which are significantly different compared to healthy controls: p = 0.005, p Proteus peptide-which are non-cross-reactive with human tissue antigens-were observed and their significant difference compared to healthy controls (p = 0.007, p mirabilis antigenic epitopes, such as in North European populations, albeit Greek RA patients presenting the cross-reaction antigen in a low percentage. These results indicate that P. mirabilis through the molecular mimicry mechanism leads to inflammation and damage of the joints in RA.

Full Text Available The binding of the tumor necrosis factor α (TNFα to its cognate receptor initiates many immune and inflammatory processes. The drugs, etanercept (Enbrel®, infliximab (Remicade®, adalimumab (Humira®, certolizumab-pegol (Cimzia®, and golimumab (Simponi®, are anti-TNFα agents. These drugs block TNFα from interacting with its receptors and have enabled the development of breakthrough therapies for the treatment of several autoimmune inflammatory diseases, including rheumatoid arthritis, Crohn’s disease, and psoriatic arthritis. In this review, we describe the latest works on the structural characterization of TNFα–TNFα antagonist interactions related to their therapeutic efficacy at the atomic level. A comprehensive comparison of the interactions of the TNFα blockers would provide a better understanding of the molecular mechanisms by which they neutralize TNFα. In addition, an enhanced understanding of the higher order complex structures and quinary structures of the TNFα antagonists can support the development of better biologics with the improved pharmacokinetic properties. Accumulation of these structural studies can provide a basis for the improvement of therapeutic agents against TNFα for the treatment of rheumatoid arthritis and other autoimmune inflammatory diseases in which TNFα plays an important role in pathogenesis.

The purpose of this study was to evaluate the prevalence and clinical significance of anti-cyclic citrullinated peptide antibodies (anti-CCP-Abs), IgM and IgA rheumatoid factors (RFs) in primary Sjögren's Syndrome (pSS). We compared clinical and serological characteristics of 31 pSS and 31 Rheumatoid Arthritis (RA) patients. Both, anti-CCP-Abs and RFs (IgM, IgA) directed against Fc determinants of IgG from humans and rabbit were detected by enzyme-linked immunosorbent assay (ELISA). We included 31 blood donors as control group for the evaluation of RFs and anti-CCP-Abs. Nine (29%) pSS patients presented arthritis, and 10 (32,3%) RA patients also had secondary Sjögren's syndrome (sSS) RESULTS: IgM and IgA RFs prevalence was similar in pSS and RA, whichever the antigene (Human or Rabbit IgG) used. However, RA patients with sSS showed a tendency to present more often RF positivity, longer disease duration and higher ESR and CRP when compared with pSS patients with arthritis. Anti-CCP-Abs were detected in 64,5% of RA patients and in only 6,9% of pSS patients (p<0,0005). Anti-CCP-Abs were more often positive in RA patients with sSS (RA/sSS) (8 patients, 80%) than in RA patients without sSS (18 patients, 58,1%), and were absent in pSS patients with arthritis. RF-positive pSS patients presented more often pulmonary involvement and higher inflammatory parameters, and less often neuropathy compared to RF-negative patients. In controls, anti-CCP-Abs were absent and RFs were negligible. Anti-CCP-Abs were detected in only a few pSS patients, none of whom presented arthritis, which contrasts with the high frequency of these antibodies in RA/sSS. These results suggest that anti-CCP-Abs could be useful in the distinction between pSS and RA with sSS. Although not useful for the differential diagnosis between RA and pSS, RFs may have a prognostic role in pSS.

Full Text Available Abstract. To study the value of antibodies to cirtullinated antigens in diagnosis and their significance in prediction of erosion formation of rheumatoid arthritis (RA, we examined serological status in 129 patients with early RA (ERA and 55 cases of undifferentiated arthritis, lasting less than 12 months. Another group consisted of 39 patients with long-standing rheumatoid arthritis, in whom the disease persisted for > 2 years. Control group included 39 patients with osteoarthrosis and 29 patients with reactive arthritis. The titers of rheumatoid factor (RF, antikeratin antibodies (AKA, antiperinuclear factor (APF and antibodies to cyclic citrullinated peptide (anti-CCP were studied during initial examination and 12 months later. Serial cryosections of rat esophagus and normal human buccal epithelial cells served as substrates for AKA and APF detection. AntiCCPs were revealed by means of DIASTAT technique (Axis Shield, UK.Upon initial observation of the patients with ERA, sensitivity and specificity of anti-CCP was, resp., 63.5% and 97,8%, thus exceeding both parameters for RF (48,8% и 86,7%. Sensitivity of AKA and APF for the same group was 17% and 24 %, with specificity of 97.7%. In RF-seronegative cases of early RA, anti-CCP were detected in 37% with ERA and 42% long-standing RA. In patients with non-differentiated arthritis who developed RA within one year, RF and anti-CCP were found in 12,2% and 45,5%. Following a one-year observation, a statistically significant increase was found in incidence of RF and anti-CCP in ERA patients.Positivity for anti-citrulline antibodies (AKA, APF and anti-CCP in ERA patients were associated with higher levels of CRP, increased HAQ, DAS4, Sharp scores, as compared to the patients who were seronegative. In ERA patients positive for anti-citrulline antibodies, higher frequencies of synovitis and erosive arthritis were detected by means of ultrasound and magnetic resonance imaging. In the patients with ERA

To identify the laboratory markers of disease activity, by finding relationship of biochemical markers with clinical disease activity measurement in patients suffering from rheumatoid arthritis (RA). Study Design: Cross sectional analytical study. Place and duration of study: Department of Immunology, Armed Forces Institute of Pathology (AFIP), Rawalpindi from January 2009 to January 2010 in collaboration with Fauji Foundation Hospital and Military Hospital Rawalpindi. Patients and Methods: One hundred patients diagnosed as having rheumatoid arthritis (RA) as per American college of Rheumatology (ACR) revised criteria 1987 and fulfilling the study's inclusion criteria were studied. These patients were assessed clinically according to Simplified Disease Activity Index (SDAI) and divided into three groups which were mild, moderate and severe based on disease activity. These three groups were then assessed for disease activity by Rheumatoid factor (RA factor), Anti Cyclic Citrullinated Peptide antibodies (anti CCP antibodies), Erythrocyte Sedimentation Rate (ESR) and C- Reactive Proteins (CRP). The association of these laboratory markers with three groups of disease activity was analyzed to detect most sensitive disease activity markers for RA. Results: All the assessed laboratory markers that are RA factor, anti CCP antibodies, ESR and CRP are directly related with RA disease activity and any of them can be used to assess disease activity in RA. However a combination of the tests, analyzed in this study markers maybe used for better prediction of disease activity Conclusion: The identification of the laboratory markers of disease activity may help physician to diagnose aggressive disease early and evaluate prognosis in RA patients.

To evaluate the effectiveness of an intervention on cardiovascular risk factors (CVRF) in patients with rheumatoid arthritis. After determining their CVRF and cardiovascular risk (CVR) by modified SCORE, we gave the patients a letter for their general practitioners in which they were requested for their cooperation in controlling CVRF and where the therapeutic goal for LDL cholesterol was specified. Three months later, any therapeutic intervention was recorded as well as the results. We included 211 patients, 29% with a high CVR. There were new diagnoses of CVRF in 100 patients (47%). The general practitioner changed the treatment in 2/12 diabetes, 30/84 HBP, 74/167 with elevation of LDL cholesterol and 21/51 with hypertriglyceridemia. The percentage of patients with good control over CVRF was: a) in HBP, 25 to 73%; b) elevation of LDL cholesterol from 10 to 17%; and c) in hypertriglyceridemia, 25 to 38%. Through this intervention, a new CVRF was diagnosed in nearly half of the patients. The effectiveness of the intervention on CVRF was low. Copyright © 2016 Elsevier España, S.L.U.

Filipe Araújo

2015-01-01

Full Text Available Rheumatoid arthritis’ synovitis affects mostly small hand and feet joints, although it may compromise any joint with a synovial lining. Cervical involvement occurs usually in longstanding disease in over half of these patients. We report the case of a 35-year old male patient who was referred to our outpatient clinic for a 2-year severe and disabling inflammatory neck pain, with incomplete response to intramuscular non-steroidal anti-inflammatory drugs and unremarkable cervical imaging studies. He also mentioned self-limited episodes of symmetric polyarthralgia involving hands, wrists, elbows, knees and feet, which started after his cervical complaints. On laboratorial workup, positive rheumatoid factor and anti-citrullinated peptide antibody and negative HLA-B27 were found. Cervical spine magnetic resonance imaging revealed atlantoaxial subluxation and odontoid process inflammatory pannus and erosions. Rheumatoid arthritis with cervical spine involvement as initial manifestation of disease was the definite diagnosis. The patient was started on methotrexate and prednisone and he was referred to neurosurgery outpatient clinic for cervical spine fixation.

Full Text Available Rheumatoid arthritis in women differs by more clinical course of pathologic process, and injury of certain joints depends on patient’s gender (changes of sacroiliac joints, development of tendovaginitis, intraarticular Hoffa bodies are more often being detected in men, whereas in women — proximal interphalangeal joints of fingers and toes, supramaxillary and knee joints. There is sexual dimorphism of the integral extraarticular (systemic manifestations of rheumatoid arthritis, is this case more frequent damage of lungs and peripheral nervous system is attributable to men, and Sjogren syndrome and changes in central nervous system are observed only in women’s group. Indicators of bone metabolism change in blood serum of patients with rheumatoid arthritis, besides patients with osteoporosis have the commonality and gender differences in concentrations of osteoassociated hormones and chemical elements.

LEVELS OF ANGIOGENESIS-REGULATORY CHEMOKINES IN THE SYNOVIAL FLUID OF PATIENTS WITH RHEUMATOID ARTHRITIS

Directory of Open Access Journals (Sweden)

D. A. Zhebrun

2015-01-01

Full Text Available The role of chemokines in the immunopathogenesis of rheumatoid arthritis (RA has been actively investigated in recent years. Angiogenic and angiostatic chemokines are important mediators of angiogenesis in the development and extent of pannus. Peripheral blood and synovial fluid (SF is a major biomaterial in clinical and immunological studies. At the same time, it is the SF test that may yield the most informative results since that gives an idea of the processes that occur locally within a joint. Objective: to perform a comparative analysis of the levels of a number of CXC, CC, and CX3C chemokines in the SF of patients with RA, osteoarthritis (OA, and joint injuries. Subjects and methods. The multiplex analysis using xMAP technology (Luminex, USA was used to analyze levels of CXC, CC, and CX3C chemokines in SF and serum of patients with RA (n = 20, OA (n = 9 and controls (n = 9. Results and discussion. The SF levels of CCL24/eotaxin-2, as well as those of the angiostatic chemokines CXCL9/MIG, CXCL10/IP10, CXCL11/ITAC, and CXCL13/BCA-1 were higher in the RA group than in the control and OA groups. There was a direct correlation between SF levels of CCL5/RANTES and DAS28, as well as patient global disease activity assessment on visual analogue scale, and that between the level of CCL2/MCP-1 in the SF and that of anticyclic citrullinated peptide (anti-CCP antibodies in the serum. The SF concentrations of CXCL5/ENA78 and CXCL7/NAP-2 were shown to depend on the presence of serum anti-CCP. Serum CXCL13/BCA-1 levels were higher in RA than those in OA, as that of CXCL7/NAP-2 than in the control group.

Rheumatoid arthritis: identifying and characterising polymorphisms using rat models

Science.gov (United States)

2016-01-01

ABSTRACT Rheumatoid arthritis is a chronic inflammatory joint disorder characterised by erosive inflammation of the articular cartilage and by destruction of the synovial joints. It is regulated by both genetic and environmental factors, and, currently, there is no preventative treatment or cure for this disease. Genome-wide association studies have identified ∼100 new loci associated with rheumatoid arthritis, in addition to the already known locus within the major histocompatibility complex II region. However, together, these loci account for only a modest fraction of the genetic variance associated with this disease and very little is known about the pathogenic roles of most of the risk loci identified. Here, we discuss how rat models of rheumatoid arthritis are being used to detect quantitative trait loci that regulate different arthritic traits by genetic linkage analysis and to positionally clone the underlying causative genes using congenic strains. By isolating specific loci on a fixed genetic background, congenic strains overcome the challenges of genetic heterogeneity and environmental interactions associated with human studies. Most importantly, congenic strains allow functional experimental studies be performed to investigate the pathological consequences of natural genetic polymorphisms, as illustrated by the discovery of several major disease genes that contribute to arthritis in rats. We discuss how these advances have provided new biological insights into arthritis in humans. PMID:27736747

An unusual cause of pain post ankle arthrodesis in patients with rheumatoid arthritis.

LENUS (Irish Health Repository)

Burke, Neil G

2012-02-01

Rheumatoid arthritis is an autoimmune disease which frequently affects the ankle and foot. End stage ankle arthritis from rheumatic disease is commonly managed by the established practice of ankle arthrodesis. Among the adverse sequelae causing pain following this surgery is infection, pseudo-arthrosis and non-union. Stress fracture of the distal third is a recognised but unusual cause of pain of tibia following ankle arthrodesis. The authors\\' present three patients with rheumatoid arthritis who sustained a stress fracture of the distal tibia following arthrodesis, and discuss the contributing factors and highlight the need for orthopaedic surgeons to be suspicious of this complication post surgery.

Full Text Available OBJECTIVES: Hydroxychloroquine is an antimalarial agent that has been used in systemic lupus erythematosus and rheumatoid arthritis treatment for many years. Recently, novel mechanisms of action have been proposed, thereby broadening the therapeutic perspective of this medication. The purpose of this study was to evaluate the immunomodulatory activity of hydroxychloroquine in T helper 17 (Th17 cytokines in healthy individuals and patients. METHODS: Eighteen female patients with systemic lupus erythematosus (mean age 39.0±12.9 years and 13 female patients with rheumatoid arthritis (mean age 51.5±7.7 years were recruited from Universidade Federal de Pernambuco-Brazil. The patients were included after fulfilling four classification criteria for systemic lupus erythematosus or rheumatoid arthritis from the American College of Rheumatology. After being stimulated with phorbol 12-myristate 13-acetate and ionomycin in the absence or presence of different concentrations of hydroxychloroquine, the interleukin 6, 17 and 22 levels were quantified with an enzyme-linked immunosorbent assay in culture supernatants of peripheral blood mononuclear cells from healthy individuals and patients. RESULTS: We demonstrated that in peripheral blood mononuclear cells from healthy volunteers and in systemic lupus erythematosus and rheumatoid arthritis patients, there was a significant reduction in the IL-6, IL-17 and IL-22 supernatant levels after adding hydroxychloroquine. CONCLUSIONS Our in vitro results demonstrated that hydroxychloroquine inhibits IL-6, IL-17 and IL-22 production and contributes to a better understanding of the mechanism of action of this medication.

Full Text Available Rheumatoid arthritis (RA is a classic autoimmune disease associated with the production of wide range of autoantibodies, and their detection has diagnostic and prognostic implication. The objective of this study was to estimate the diagnostic value of antibodies against modified citrullinated vimentin (AMCV and nuclear antigen RA33 of the IgA rheumatoid factor (RF versus the value of routinely used profile of autoantibodies in diagnostic work-up of RA. Material and methods. 253 patients with RA prehistory of varying duration were included into the study group. The control group was comprised of 92 patients, including patients with seronegative spondyloarthropathies and diffuse connective tissue diseases, as well as sex and age matched healthy controls. Serum levels of IgM and IgA RF, antibodies against cyclic citrullinated peptide (ACCP, ACMV, anti-keratin antibodies (AKA, antibodies against RA33 antigen (ARA33 and antinuclear factor (ANF were measured in all patients and controls. Results and discussion. Diagnostic sensitivity of AMCV equaled 78%, ACCP — 77%, IgM RF — 71%, IgA RF — 43%, AKA — 43%, ARA33 — 31% and ANF — 31%. All anti-citrullinic antibodies (AKA, ACCP, ACMV were significantly more commonly associated with IgM RF. Among RF and ACCP seronegative patients ACMV were found in 24% cases with 20 IU/Ml detection threshold, and in 21% — with 30 IU/Ml, allowing to increase diagnostic specificity of the test up to 91% with the increment of diagnostic threshold. Incidence of ARA33 was not significantly different among the RF and ACCP positive or negative subgroups, thus making ARA33 an independent RA marker. Specificity of this marker was 87,9%, thus making it inferior to RF and ACCP by a composite of diagnostic characteristics. Conclusions. Integrated measurement of ACMV and ARA33 is a rational approach at the second stage of serologic testing work-up in suspected cases of RA onset, when initial RF and ACCP tests were negative.

To evaluate the radiographic findings of epitrochlear lymphadenopathy with regard to the distribution and severity of the disease and clinal parameters in patients with rheumatoid arthritis. Forty six patients with rheumatoid arthritis in whom epitrochlear oval-shaped densities were seen on radiographs were involved in this study. There were 14 cases of unilateral epitrochlear lymphadenopathy in which bilateral arthritic evidence was revealed by radiographs (mixed group), and 32 of bilateral lymphadenopathy in which there was arthritic evidence (positive group). Twenty-three patients in whom lymphadenopathy was not seen on radiographs of the elbow and who were diagnosed as suffering from rheumatoid arthritis functioned as controls (negative group).For scoring the degree of arthritis using the simplified scoring method proposed by Kaye et al., joints were divided into six groups, as follows: Joint 1, elbow; Joint 2, wrist; Joint 3, radial (1st and 2nd) PIP and MCP; Joint 4, ulnar (3rd, 4th, 5th) PIP and MCP; Joint 5, Joints 1 + 2+ 3 + 4; Joint 6, Joints 1 + 4. For each joint, scores were compared with those on the contralateral side in the mixed group. Differences in clinical parameters ( disease duration, rheumatoid factor, ESR, and CRP), and scores for each joint in each arm were statistically compared between be positive and negative group. The number, mean diameter, and maximal diameter of epitrochlear lymph nodes were calculated and correlated with clinical parameters and scores for each joint. To evaluate the incidence of epitrochlear lymphadenopathy without radiographic evidence of arthritis in 46 patients (78 arms) with lymphadenopathy, the frequency of cases in which the score for the joint was zero was assessed. In the mixed group, the mean score for Joint 6 of the arm with epitrochlear lymphadenopathy was significantly higher than that for the contralateral side in the mixed group (p=3D0.022). Only CRP was significantly higher in the positive group than

Radiographs were reviewed in a group of nine patients with classical seropositive rheumatoid arthritis who on tissue typing were found to express the class I HLA-B27 allele. Radiographs were analyzed with regard to whether or not they demonstrated radiographic features of (1) classical rheumatoid arthritis, (2) seronegative arthritis, or (3) mixed features of rheumatoid and seronegative arthritis. Five patients (55%) displayed radiographic features consistent with a diagnosis of rheumatoid arthritis, two patients (22%) showed radiographic features of seronegative disorder (periostitis and sacroiliitis), and two patients (22%) showed a mixed picture with evidence of both rheumatoid arthritis and a seronegative disorder. Thus, the HLA-B27 allele contributed to the radiographic features in 44% of patients with rheumatoid arthritis and associated HLA-B27. Thus, the wide range of findings in our population indicates that the radiographic attributes are not specific enough to constitute a unique subpopulation of patients with rheumatoid arthritis.

Proton induced X-ray emission (PIXE) analysis is used to measure trace element concentrations in blood serum from patients with rheumatoid arthritis. Initially trace element contaminations in blood-collecting and storing devices are determined. Then mean values and nyctemeral cycles are measured both in normal subjects and patients with rheumatoid arthritis and other similar pathologies. Abnormal concentrations of Cu and Zn and anomalies in the nyctemeral cycle are found in the patients. In the second phase of the project, the special case of chrysotherapeutically treated (gold salt treatment) rheumatoid arthritis patients is studied for extended periods of time (up to 53 weeks).

For the study of the temporomandibular joint in rheumatoid arthritis 30 patients were selected who were diagnosis as rheumatoid arthritis through the clinical, radiographic examination and laboratory finding. Temporoman dibular joint involvement was evaluated through the clinical, radiographic examination. The results were as follows; 1. TMJ was involved in 15 patients of 30 patients with rheumatoid arthritis. (50% involvement). 2. Duration of rheumatoid arthritis was more longer in patients with TMJ involvement than in patients without TMJ involvement. 3. Osseous changes in TMJ were in order of frequency erosion, flattening, osteophyte, sclerosis, deformity, and most common involved site was mandibular condyle. 4. Most common positional change of condyle was forward position in centric occlusion, and restricted movement of condyle in 1 inch mouth opening. 5. TMJ involvement of rheumatoid arthritis was almost bilateral. 6. Main symptoms of TMJ were pain, stiffness, tenderness, limitation of mouth opening, crepitation. 7. There was not the case of ankylosis. 8. There was statistically insignificant correlation between mandibular deviation and TMJ involvement, but some cases showed severe deviation on mouth opening.

Ten patients with refractory rheumatoid arthritis were given 3000 rad of fractionated total lymphoid irradiation in an uncontrolled therapeutic trial. Total lymphoid irradiation was associated with objective evidence of considerable clinical improvement in eight patients and with reduced blood lymphocyte counts in all 10. On completion of irradiation, there was an abrogation of lymphocyte reactivity in vitro in the patients with clinical responses, but abnormal antibody activities characteristic of rheumatoid arthritis and normal components of humoral immunity were not suppressed. Partial recrudescence of arthritis occurred shortly after a year after the completion of irradiation and was paralleled by a restitution of lymphocyte concentrations and responsiveness to mitogens to levels similar to those observed before irradiation. These data provide further evidence of T-cell involvement in the pathogenesis of rheumatoid arthritis and demonstrate that total lymphoid irradiation can induce temporary relief, but they do not ascertain whether the natural history of this disease was altered

The TAM receptor tyrosine kinases (TAM RTK) are a subfamily of receptor tyrosine kinases, the role of which in autoimmune diseases such as systemic lupus erythematosus has been well explored, while their functions in rheumatoid arthritis (RA) remain largely unknown. In this study, we investigated the role of soluble TAM receptor tyrosine kinases (sAxl/sMer/sTyro3) in patients with RA. A total of 306 RA patients, 100 osteoarthritis (OA) patients and 120 healthy controls (HCs) were enrolled into this study. The serum concentrations of sAxl/sMer/sTyro3 were measured by enzyme-linked immunosorbent assay (ELISA), then the associations between sAxl/sMer/sTyro3 levels and clinical features of RA patients were analysed. We also investigated whether sTyro3 could promote osteoclast differentiation in vitro in RA patients. The results showed that compared with healthy controls (HCs), sTyro3 levels in the serum of RA patients were elevated remarkably and sMer levels were decreased significantly, whereas there was no difference between HCs and RA patients on sAxl levels. The sTyro3 levels were correlated weakly but positively with white blood cells (WBC), immunoglobulin (Ig)M, rheumatoid factor (RF), swollen joint counts, tender joint counts, total sharp scores and joint erosion scores. Conversely, there were no significant correlations between sMer levels and the above indices. Moreover, RA patients with high disease activity also showed higher sTyro3 levels. In-vitro osteoclast differentiation assay showed further that tartrate-resistant acid phosphatase (TRAP) + osteoclasts were increased significantly in the presence of sTyro3. Collectively, our study indicated that serum sTyro3 levels were elevated in RA patients and correlated positively with disease activity and bone destruction, which may serve as an important participant in RA pathogenesis. © 2017 British Society for Immunology.

Motivated by the results of a hospital study on rheumatoid arthritis (RA) in Lesotho (southern Africa) a survey of inflammatory polyarthritis (IP) and RA was undertaken in a sample of the rural population of that country. Contrary to expectations the prevalence of IP grades 2-4 (definite disease) was low (0.4%) and equal in both sexes, while probable and definite RA combined (American Rheumatism Association (ARA) criteria) occurred in 1.8% of both males and females. RA was slightly more severe than in other rural African Negro studies but less so when compared with the disease condition of the patients observed in the hospital study. Rheumatoid factor and particularly that directed against heterologous antigen occurred in 41% of the RA patients and in 16% of the controls. Two thirds of the definite cases and 29% of the combined probable and definite group showed radiological abnormalities. PMID:3740998

Objective: To detect the anti cyclic citrullinated peptide (Anti-CCP) antibody in rheumatoid arthritis (RA) patients to determine its diagnostic value in Pakistani patients. Study Design: Cross sectional study. Place and Duration of Study: Military Hospital (MH) Rawalpindi, from January 2013 to June 2015. Material and Methods: A total of 58 patients with complications of rheumatoid arthritis were recruited in the study using convenient sampling technique after their informed consent. Age and gender of the patients were recorded. Blood was collected from the patients subjected to ELISA based detection of anti-CCP and latex agglutination test for detection of Rheumatoid Factor (RF). Data obtained were analyzed using Microsoft excel 2010. Results: Among the fifty eight RA patients, 40 percent were males and 60 percent were females. Age ranged between 12 to 80 years (mean age 49.74 +- 16.81 years) of the males RA patients and was higher as compared to females (mean age 43.2 +-16.70 years). ELISA based detection of anti-CCP antibody showed that about 91 percent of RA patients were positive for anti CCP antibody. About 72 percent were positive for anti CCP antibody alone, 19 percent were positive for both anti-CCP and RF and 9 percent were positive for RF. Conclusion: The results concluded that a higher percentage of the RA patients are positive for anti-CCP antibody marking its importance as a diagnostic marker. Anti-CCP has more sensitivity as compared to RF in RA patients. (author)

HETEROGENEITY OF POLYCLONAL IMMUNOGLOBULINS NUCLEASE ACTIVITY IN RHEUMATOID AND REACTIVE ARTHRITIS

2017-01-01

Full Text Available Catalytic properties of immunoglobulins are widely studied within recent years. It was found that nuclease activity of immunoglobulins is increased in systemic autoimmune diseases. Given some pathogenetic features of rheumatoid arthritis and reactive arthritis, it is appropriate to clarify the nature of nuclease activity in these diseases. Determination of DNAse activity of immunoglobulins with different DNA substrates, and search for specific substrates for distinct clinical entities could serve these purposes. The aim of present work is to determine DNase activity of the polyclonal class G immunoglobulins in rheumatoid and reactive arthritis using various methods.Different methods are used to evaluate nuclease activity. In this paper we present newly developed and modified techniques for determination of DNAse activity of polyclonal IgGs. Particular attention was paid to the electrophoretic method of DNase activity assessment. Polyclonal IgG isolated from blood serum of patients with rheumatoid arthritis and reactive arthritis were used for assays. In this study, we demonstrated the presence of an inhomogeneous DNase activity of immunoglobulins in relation to different substrates.Along with calf thymus DNA, we used bacterial plasmid DNA and PCR products based on bacterial gene sequences. Levels of DNase activity by rivanol clot method with calf thymus DNA as substrate proved to be higher in patients with rheumatoid arthritis than the control values (p < 0.01. DNase abzyme activity in patients with rheumatoid arthritis was elevated, as compared to the patients with reactive arthritis (p < 0.01.When examining ability of the IgG to hydrolyze procaryotic DNA (bacterial plasmid DNA and PCR products, based on bacterial genes, we obtained heterogeneous results. Different Ig samples showed varying degrees of DNA hydrolysis. Abzyme hydrolysis of DNA substrates longer than 700 bp was more pronounced, as compared to short DNA substrates (100 base pairs

To compare the performance of an extended model and a simplified prognostic model for joint damage in rheumatoid arthritis (RA) based on 3 baseline risk factors: anticyclic citrullinated peptide antibodies (anti-CCP), erosions, and acute-phase reaction. Data were used from the Nijmegen early RA cohort. An extended model and a simplified baseline prediction model were developed to predict joint damage progression between 0 and 3 years. Joint damage progression was assessed using the Ratingen score. In the extended model, prediction factors were positivity for anti-CCP and/or rheumatoid factor, the level of erythrocyte sedimentation rate, and the quantity of erosions. The prediction score was calculated as the sum of the regression coefficients. In the simplified model, the prediction factors were dichotomized and the number of risk factors was counted. Performances of both models were compared using discrimination and calibration. The models were internally validated using bootstrapping. The extended model resulted in a prediction score between 0 and 5.6 with an area under the receiver-operation characteristic (ROC) curve of 0.77 (95% CI 0.72-0.81). The simplified model resulted in a prediction score between 0 and 3. This model had an area under the ROC curve of 0.75 (95% CI 0.70-0.80). In internal validation, the 2 models showed reasonably well the agreement between observed and predicted probabilities for joint damage progression (Hosmer-Lemeshow test p > 0.05 and calibration slope near 1.0). A simple prediction model for joint damage progression in early RA, by only counting the number of risk factors, has adequate performance. This facilitates the translation of the theoretical prognostic models to daily clinical practice.

The tumor necrosis factor-α inhibitor golimumab in the treatment of rheumatoid arthritis

Full Text Available The tumor necrosis factor-α (TNF-α golimumab (GLM, that is a fully human monoclonal anti-body, was registered in Russia in 2012 to treat rheumatic diseases, such as rheumatoid arthritis (RA, ankylosing spondylitis, and psoriatic arthritis. Its distinguishing characteristics are a high affinity for TNF-α and easiness-to-use: the drug as a 0.5-ml solution is injected subcutaneously once monthly. The registration of the medication was followed by the implementation of a massive program of clinical trials. The randomized placebo-controlled GO-FORWARD, GO-BEFORE, and GO-AFTER studies have indicated that GLM is effective in patients with RA from different subgroups and has a favorable safety profile as compared to that of the entire class of biological agents. According to the data of these studies, GLM had a positive effect on the functional status and quality of life in patients with RA: there was a significantly greater decrease in HAQ scores in both the early and long open treatment phases (to 5 years and in fatigability than in the control group (p=0.032, physical and mental health improvements, as shown by the SF-36 questionnaire, and a significant reduction in disability.

Use of total lymphoid irradiation (TLI) in studies of the T cell dependence of autoantibody production in rheumatoid arthritis

International Nuclear Information System (INIS)

Tanay, A.; Strober, S.; Logue, G.L.; Schiffman, G.

1984-01-01

The effect of total lymphoid irradiation (TLI) on T cell-dependent and -independent humoral immune responses was studied in patients with intractable rheumatoid arthritis (RA). The serum levels of several autoantibodies and of antibodies to diphtheria (DT) and tetanus (TT) toxoids and to pneumococcal polysaccharide (PPS; 12 antigenic types) were studied before and after TLI. In addition, the patients were given a booster injection of DT and TT and a single injection of pneumococcal vaccine after radiotherapy. Antibody levels to DT and TT decreased about twofold after TLI and did not rise significantly after a booster injection. However, there was no reduction in antibody levels to PPS after TLI, and a significant rise in titers was observed after a single vaccination. The serum levels of rheumatoid factor (RF), anti-nuclear antibody (ANA), and granulocyte associated IgG rose slightly after TLI. Thus, the autoantibodies and antibodies to polysaccharides appear to be relatively independent of helper T cell function, which is markedly reduced after TLI. On the other hand, antibodies to protein antigens such as DT and TT appear to be more closely dependent upon T helper function in man, as has been reported in rodents. The findings suggest that T cell-independent autoantibody responses alone do not maintain the joint disease activity in RA, because improvement in joint disease after TLI has been reported

Research of cardiac involvement in patients with rheumatoid arthritis can prevent complications and place in a logical secondary prevention. The objective of this study was to investigate the echocardiographic parameters in a population of Senegalese patients with rheumatoid arthritis without clinically evident cardiovascular manifestations. We conducted a descriptive cross-sectional study, which included prospectively from outpatients in the internal medicine department of university hospital center Aristide Le Dantec in Dakar, Senegal, with a diagnosis of rheumatoid arthritis without clinically evident cardiovascular disease. It focused on a sample of 73 patients of both sexes aged at least 18 years. Following clinical examination, we conducted laboratory tests (CRP, fibrinogen, ESR, rheumatoid factors: Latex and Waaler-Rose, anti-CCP, antinuclear factors and anti-ENA antibodies), ECG, echocardiography standard. Data were analyzed using a descriptive study of the different variables with the calculation of proportions for categorical variables, and the positional parameters and dispersion for quantitative variables. A total of 73 patients with rheumatoid arthritis without obvious cardiac events and meeting the criteria of definition of the ACR 1987 were included in the study. The mean age was 44.17±14.43 years with extremes of 18 and 75 years. The mean duration of RA was 5.93±4.78 years. The concept of family inflammatory arthritis was reported in 35.60% of cases and almost one in six patients had at least a factor of cardiovascular risk (16.96%). The abnormalities found in Doppler echocardiography were dominated by diastolic LV dysfunction (42.46%), increased left ventricular mass in 35.61%. Valvular leaks of variable grades were highlighted regarding all orifices but were rarely significant. The realization of echocardiography in patients with rheumatoid arthritis without clinically evident cardiovascular manifestations helps to highlight cardiovascular

Open label pragmatic randomised multicentre two arm non-inferiority trial over 12 months. 24 rheumatology clinics in England. Patients with rheumatoid arthritis who were eligible for treatment with tumour necrosis factor inhibitors according to current English guidance were randomised to either the tumour necrosis factor inhibitor strategy or the combined disease modifying drug strategy. Biologic strategy: start tumour necrosis factor inhibitor; second biologic in six month for non-responders. Alternative strategy: start combination of disease modifying drugs; start tumour necrosis factor inhibitors after six months in non-responders. reduction in disability at 12 months measured with patient recorded heath assessment questionnaire (range 0.00-3.00) with a 0.22 non-inferiority margin for combination treatment versus the biologic strategy. quality of life, joint damage, disease activity, adverse events, and costs. Intention to treat analysis used multiple imputation methods for missing data. 432 patients were screened: 107 were randomised to tumour necrosis factor inhibitors and 101 started taking; 107 were randomised to the combined drug strategy and 104 started taking the drugs. Initial assessments were similar; 16 patients were lost to follow-up (seven with the tumour necrosis factor inhibitor strategy, nine with the combined drug strategy); 42 discontinued the intervention but were followed-up (19 and 23, respectively). The primary outcome showed mean falls in scores on the health assessment questionnaire of -0.30 with the tumour necrosis factor inhibitor strategy and -0.45 with the alternative combined drug strategy.

Objective Anti–tumor necrosis factor α (anti-TNF) therapy is a mainstay of treatment in rheumatoid arthritis (RA). The aim of the present study was to test established RA genetic risk factors to determine whether the same alleles also influence the response to anti-TNF therapy. Methods A total of 1,283 RA patients receiving etanercept, infliximab, or adalimumab therapy were studied from among an international collaborative consortium of 9 different RA cohorts. The primary end point compared RA patients with a good treatment response according to the European League Against Rheumatism (EULAR) response criteria (n = 505) with RA patients considered to be nonresponders (n = 316). The secondary end point was the change from baseline in the level of disease activity according to the Disease Activity Score in 28 joints (ΔDAS28). Clinical factors such as age, sex, and concomitant medications were tested as possible correlates of treatment response. Thirty-one single-nucleotide polymorphisms (SNPs) associated with the risk of RA were genotyped and tested for any association with treatment response, using univariate and multivariate logistic regression models. Results Of the 31 RA-associated risk alleles, a SNP at the PTPRC (also known as CD45) gene locus (rs10919563) was associated with the primary end point, a EULAR good response versus no response (odds ratio [OR] 0.55, P = 0.0001 in the multivariate model). Similar results were obtained using the secondary end point, the ΔDAS28 (P = 0.0002). There was suggestive evidence of a stronger association in autoantibody-positive patients with RA (OR 0.55, 95% confidence interval [95% CI] 0.39–0.76) as compared with autoantibody-negative patients (OR 0.90, 95% CI 0.41–1.99). Conclusion Statistically significant associations were observed between the response to anti-TNF therapy and an RA risk allele at the PTPRC gene locus. Additional studies will be required to replicate this finding in additional patient collections

Parvovirus B19 (B19V) infection is associated with various autoimmune diseases. We investigated the levels of pro-inflammatory (IFNᵧ, TNFα, IL-2, IL-12) and anti-inflammatory (IL-4, IL-10) cytokines in the plasma of B19V DNA positive (B19 + ) and negative (B19 - ) rheumatoid arthritis (RA) patients in comparison with the control group (healthy persons). Blood samples were collected from 118 patients with RA and 49 healthy voluntaries. B19V sequence was determined in whole blood and cell-free plasma DNA by nested PCR. The levels of cytokines in the plasma and cell culture medium from Concanavalin A (ConA) or B19V VP1 protein stimulated PBMC were determined by ELISA. The levels of IL-4, IL-10, IL-12, IL-2 and TNFα were higher in plasma of RA patients in comparison with control persons. B19 + controls and RA patients had lower levels of IFNᵧ in comparison with B19 - controls and RA patients. Within RA patients the plasma levels of IFNᵧ were lower in patients with low RA disease activity or remission. Plasma level of IL-4 was increased and IL-10 level was decreased in B19 + RA patients in comparison with B19 - RA patients and did not differ between B19 + and B19 - controls. B19V infection did not affect plasma levels of IL-12, IL-2, and TNFα. ConA and B19 VP1 protein stimulated PBMC from RA patients produced less IFNᵧ than stimulated PBMC from the healthy controls. B19V infection could differently modulate the amount of cytokines in the plasma of healthy persons and RA patients. Decreased production of IFNᵧ and raised level of plasma IL-4 in RA patients could lower antiviral clearance. Copyright © 2017 Elsevier Ltd. All rights reserved.

Rheumatoid myositis leading to acute lower extremity compartment syndrome: a case-based review.

Muscle pain and weakness in a rheumatoid arthritis (RA) patient has a broad differential, and myositis should be considered early in the disease course as serious limb and life-threatening sequelae may occur. A 55-year-old woman with a past medical history of methotrexate-controlled RA presented with right leg pain for 4 days. The patient suffered sensory loss in the right foot and decreased strength in the toes. Lab tests revealed elevated creatine kinase, ESR, and anti-rheumatoid factor antibody titers. CT scan revealed myositis of posterior compartment muscles. Progressive edema, pain, and neuromuscular deficits persisted despite steroid and antibiotic therapy, so the patient was taken for urgent fasciotomy for acute compartment syndrome. The muscle biopsy showed diffuse mononuclear cell infiltration as well as perivascular and perineural involvement consistent with rheumatoid myositis (RM). The patient did well post-op on a prednisone taper. This case underlines the systemic nature of RA and exemplifies the severity of inflammation that may lead to grave consequences such as compartment syndrome. The histopathology is diagnostic when there is evidence of mononuclear cell infiltration; however, this is not entirely specific. Early, aggressive therapy with immunosuppressives is warranted in such patients. RM has not, to our knowledge, been recorded to cause acute compartment syndrome. Clinicians should be aware of this uncommon manifestation of RA keeping the various presentations of rheumatoid disease in mind when faced with these patients.

Critical appraisal of efficacy and safety of abatacept in the treatment of refractory rheumatoid arthritis

Full Text Available Lisa M Lundquist1, Sabrina W Cole2, Jill M Augustine11Mercer University College of Pharmacy and Health Sciences, Atlanta, GA, 2Wingate University School of Pharmacy, Wingate, NC, USAAbstract: Rheumatoid arthritis is a chronic, progressive, autoimmune disease that leads to significant disability and premature mortality. Various treatment options are available, but the foundation of treatment includes nonbiologic and biologic disease-modifying antirheumatic drugs. The incidence of patients with rheumatoid arthritis refractory to first-line agents is estimated to be at least 20%. Abatacept, a T cell costimulation modulator, is the first agent to interfere with full T cell activation by competing with CD28 for binding of CD80 and CD86, which results in decreased secretion of proinflammatory cytokines and autoantibody production. Current American College of Rheumatology treatment guidelines recommend abatacept for patients with at least moderate disease activity and a poor prognosis demonstrating an inadequate response to other agents. Several key Phase III trials have been conducted to evaluate the efficacy and safety of abatacept in patients with an inadequate response to methotrexate or anti-tumor necrosis factor alpha therapy. Response rates in all trials showed statistically significant improvements compared with placebo according to American College of Rheumatology criteria for disease improvement. The most common adverse event report in patients receiving abatacept was infection; however, the frequency of adverse events was similar to placebo. Abatacept is a safe and effective rheumatoid arthritis treatment for patients with an inadequate response to methotrexate or anti-tumor necrosis factor alpha therapy.Keywords: abatacept, rheumatoid arthritis, treatment refractory, biologic, disease-modifying antirheumatic drugs

To evaluate health-related quality of life (HRQoL) and associated clinical, demographic and socioeconomic factors in a cohort of Ecuadorian patients with rheumatoid arthritis (RA). A cross-sectional descriptive study evaluating (HRQoL) with the Spanish version of the Quality of Life Rheumatoid Arthritis (QoL-RA) instrument in patients diagnosed with RA according to the criteria of the American College of Rheumatology and the European League Against Rheumatism. In addition, the following data were obtained: age, sex, marital status, socioeconomic stratum, comorbidities, disease duration, medication, rheumatoid factor positivity, disease activity using the simplified disease activity index and physical functionality measured with the modified Health Assessment Questionnaire (MHAQ). A total of 163 patients were assessed, the mean score of the QoL-RA scale was 6.84±1.5 points. The highest measurements were obtained in the domains of interaction (8.04±1.9) and support (8.01±2). The factors that were associated with the overall quality of life assessment were: functionality measured with MHAQ (r=-0.70; P<.001); disease duration in years (r=-0.178; P<.05); and disease activity (mean difference of 1.5; 95%CI: 1.09 to 1.91). The patients evaluated had a good to moderate HRQoL. The domains related to support and social life were those with the highest scores and the lowest scores were related to pain and nervous tension. Functionality, duration, and disease activity were statistically associated with HRQoL.

2017-08-01

To assess the prevalence of gallstone disease and identify associated risk factors in rheumatoid arthritis (RA) patients compared to the general population. Eighty-four women with rheumatoid arthritis were included in the study. Each patient was assessed via a structured interview, physical examination, abdominal ultrasound and blood test including lipid profile. The prevalence of gallstone disease in rheumatoid arthritis was compared with data from a study of the Spanish population matched by age groups. Twenty-eight of the 84 women had gallstone disease (33.3%). RA women with and without gallstone disease were similar in most of the variables assessed, except for older age and menopausal status in the former. A greater prevalence of gallstone disease was seen in rheumatoid arthritis patients compared to the general population of the same age; however, the differences were significant only in women aged 60 or older (45.5% versus 23.1% respectively, P-value .008). The age-adjusted OR of developing gallstone disease in RA women compared with general population women was 2,3 (95% CI: 1.3-4.1). A significantly higher HDL3-c subfraction and higher apoA-I/HDL and HDL3-c/TC ratios were observed in patients with gallstone disease. Women with rheumatoid arthritis may have a predisposition to gallstones that can manifest in middle or older age compared with women in the general population. This situation could be related to chronic inflammation and HDL metabolism. Copyright © 2017 Elsevier España, S.L.U. and Sociedad Española de Reumatología y Colegio Mexicano de Reumatología.

Rheumatoid arthritis and the challenge of using nanoparticles for its treatment

Directory of Open Access Journals (Sweden)

Chabib Lutfi

2018-01-01

Full Text Available Rheumatoid arthritis is the most common autoimmune disease that affects the joints. The cause of the disease is unknown, many studies proposed hypothesis about the etiology of rheumatoid arthritis. The clinical manifestations of arthritis are different in each patients. In addition, the development of the medication is still continue to achieve the most effective role with less side effect. Nanoparticles may be the answer to this problem, since they have been widely used to improve the pharmacokinetic and pharmacodynamics of rheumatoid arthritis drugs. Using nanoparticles-tagged folate or PEG to deliver rheumatoid arthritis drugs may increase the specificity of the drugs to the target and consequently, may decrease the side effects of the drugs. The purpose of this review is to summarize the etiology, clinical manifestation and highlighting the use of nanoparticles in rheumatoid arthritis treatment.

Rheumatoid Arthritis and Incidence of Twelve Initial Presentations of Cardiovascular Disease: A Population Record-Linkage Cohort Study in England.

Mar Pujades-Rodriguez

Full Text Available While rheumatoid arthritis is an established risk factor for cardiovascular disease (CVD, our knowledge of how the pattern of risk varies for different cardiovascular phenotypes is incomplete. The association between rheumatoid arthritis and the initial presentation of 12 types of CVDs were examined in a contemporary population of men and women of a wide age range.CALIBER data, which links primary care, hospital and mortality data in England, was analysed. A cohort of people aged ≥18 years and without history of CVD was assembled and included all patients with prospectively recorded rheumatoid arthritis from January 1997, until March 2010, matched with up to ten people without rheumatoid arthritis by age, sex and general practice. The associations between rheumatoid arthritis and the initial presentation of 12 types of CVDs were estimated using multivariable random effects Poisson regression models.The analysis included 12,120 individuals with rheumatoid arthritis and 121,191 comparators. Of these, 2,525 patients with and 18,146 without rheumatoid arthritis developed CVDs during a median of 4.2 years of follow-up. Patients with rheumatoid arthritis had higher rates of myocardial infarction (adjusted incidence ratio [IRR] = 1.43, 95%CI 1.21-1.70, unheralded coronary death (IRR = 1.60, 95%CI 1.18-2.18, heart failure (IRR = 1.61, 95%CI 1.43-1.83, cardiac arrest (HR = 2.26, 95%CI 1.69-3.02 and peripheral arterial disease (HR = 1.36, 95%CI 1.14-1.62; and lower rates of stable angina (HR = 0.83, 95%CI 0.73-0.95. There was no evidence of association with cerebrovascular diseases, abdominal aortic aneurysm or unstable angina, or of interactions with sex or age.The observed associations with some but not all types of CVDs inform both clinical practice and the selection of cardiovascular endpoints for trials and for the development of prognostic models for patients with rheumatoid arthritis.

Oxidative stress and immune imbalance play an important role in the pathogenesis of rheumatoid arthritis (RA). Bilirubin is a powerful antioxidant and also regarded as immunomodulator. Increased evidence shows that bilirubin should be a protective factor for autoimmune disease. However, the relationship between bilirubin and RA remain unclear. We analyzed serum bilirubin levels and other laboratory and clinical data in 130 RA patients (35 patients without any complications), 81 osteoarthritis (OA) patients and 96 healthy controls. Binary logistic regression adjusted by age and gender revealed that the levels of serum total, indirect bilirubin were significantly lower in RA patients, when compared with healthy controls (P=.015, OR=0.767, 95% CI=0.619-0.951; P=.010, OR=0.664, 95% CI=0.487-0.906, respectively) or OA patients (P=.000, OR=0.763, 95% CI=0.661-0.882; P=.000, OR=0.656, 95% CI=0.532-0.808, respectively). A reduced trend of levels of bilirubin has been detected along with increased disease activity, despite with no significance (P>.05). Spearman rank test further demonstrated that IgG and ESR were negative associated with total, indirect bilirubin, and albumin, prealbumin, APOA, HDL-C were positively associated with bilirubin. In conclusion, the levels of serum bilirubins were decreased in RA, and decreased levels could be associated with IgG, albumin and inflammatory marker ESR. © 2017 Wiley Periodicals, Inc.

Rheumatoid nodule of the foot: MRI appearances mimicking an indeterminate soft tissue mass

International Nuclear Information System (INIS)

Sanders, T.G.; Linares, R.; Su, A.

1998-01-01

Subcutaneous rheumatoid nodules occur commonly in advanced cases of rheumatoid arthritis, but only rarely appear in the feet. We present a case of a subcutaneous rheumatoid nodule arising in the heel pad of a 68-year-old man with a long history of rheumatoid arthritis, along with a review of the literature. The appearance of the mass on MRI is illustrated and correlated with the histologic findings. The MRI appearance of a subcutaneous rheumatoid nodule is that of a nonspecific ill-defined mass with long T1- and long T2-relaxation times. A differential diagnosis for similar appearing masses is offered. (orig.)

To examine the psychometric properties of the Arthritis Body Experience Scale (ABES) in a US sample of people with osteoarthritis, rheumatoid arthritis, fibromyalgia and other rheumatic conditions. The ABES, with the scoring direction modified, was phone-administered to 937 individuals who self-identified as having one or more arthritis conditions based on a validated, US, national survey assessment tool. Descriptive statistics of demographic variables and factor analysis of scale items were conducted. Scale dimensionality was assessed using principal component analysis (PCA) with oblique rotation. Criteria for assessing factors were eigenvalues > 1, visual assessment of scree plot, and structure and pattern matrices. The predominantly female (74.2%) and Caucasian (79.9%) sample had a mean age of 61.0 ± 13.1 years, and a mean BMI of 30.2 ± 7.1. Major arthritis conditions reported were rheumatoid arthritis, osteoarthritis and fibromyalgia. A three-factor structure with cronbach alpha values of .84, .85 and .53 was elicited, and accounted for 72% of the variance. Compared to the two-factor structure evidenced by the original ABES scale in a sample of UK adults, the data from this sample evidenced a three-factor structure with higher variance. The third factor's cronbach alpha of .53 was low and could be improved by the addition of salient questions derived from further qualitative interviews with patients with arthritis and other rheumatic conditions and from current literature findings. The observed psychometrics indicate the scale usefully assesses body image in populations with arthritis and related conditions. However, further testing and refinement is needed to determine its utility in clinical and other settings.

Coexistence of bronchiectasis and rheumatoid arthritis: revisited.

Wilczynska, Maria M; Condliffe, Alison M; McKeon, Damian J

2013-04-01

The presence of bronchiectasis (BR) in patients with rheumatoid arthritis (RA) has been recognized for many decades; nevertheless, little research has been undertaken in this area. It is important to recognize that BR coexistent with RA differs from the other types of BR. The purpose of this descriptive review was to delineate the epidemiology, etiology, risk factors, pulmonary function testing, imaging, prognosis and management of concomitant BR and RA. To inform our study we searched the PubMed, EMBASE, CINAHL, and MEDLINE databases, using combinations of the following key words: computed tomography, lung function tests, rheumatoid arthritis, bronchiectasis, biological agents, and interstitial lung disease. The number of published papers covering this topic is limited, but several relevant conclusions can be drawn. Patients with concomitant RA and BR have worse obstructive airways disease, increased susceptibility to recurrent pulmonary infections, faster lung function decline, and higher mortality, compared with subjects with either RA or BR alone. The use of disease-modifying anti-rheumatic drugs (both biological and non-biological) for RA in RA-BR patients imparts a further challenge in managing these patients. Although there are not any published guidelines on the management of coexisting RA-BR, we have attempted to provide such recommendations, based on the literature review and our experience.

B Lymphocytes in Rheumatoid Arthritis and the Effects of Anti-TNF-α Agents on B Lymphocytes: A Review of the Literature.

Science.gov (United States)

Pala, Ozlem; Diaz, Alain; Blomberg, Bonnie B; Frasca, Daniela

2018-05-22

The aim of this article was to review published research related to B lymphocytes in rheumatoid arthritis, their role in the pathogenesis of the disease, the effects of tumor necrosis factor (TNF)-α inhibitors on B lymphocytes, the risk for infection, and responses to vaccines. A PubMed search was conducted to review recent advances related to B lymphocytes and the effects of anti-TNF-α on B lymphocytes in rheumatoid arthritis. B lymphocytes play an important role in the pathogenesis of rheumatoid arthritis. In this review, we summarize the major mechanisms by which B lymphocytes play a pathologic role in the development and propagation of the disease, as B lymphocytes are recruited to the synovial fluid, where they contribute to local inflammation through the secretion of pro-inflammatory mediators (cytokines, chemokines, micro-RNAs) and present antigens to T cells. We discuss the effects of TNF-α, either direct or indirect, on B lymphocytes expressing receptors for this cytokine. We also show that total B-cell numbers have been reported to be reduced in the blood of patients with rheumatoid arthritis versus healthy controls, but are significantly increased up to normal levels in patients undergoing anti-TNF-α therapy. As for B-cell subsets, controversial results have been reported, with studies showing decreased frequencies of total memory B cells (and memory subsets) and others showing no differences in patients versus healthy controls. Studies investigating the effects of anti-TNF-α therapy have also given controversial results, with therapy found to increase (or not) the frequency of memory B lymphocytes, in patients with rheumatoid arthritis versus healthy controls. Those highly variable results could have been due to differences in patient characteristics and limited numbers of subjects. Finally, we summarize the effects of blocking TNF-α with anti-TNF-α agents on possible infections that patients with rheumatoid arthritis may contract, as well as on

Full Text Available In the present study, we evaluated 42 wrists using the semi-quantitative scales power Doppler ultrasound (PDUS and gray scale ultrasound (GSUS with scores ranging from 0 to 3 and correlated the results with clinical, laboratory and radiographic data. Twenty-one patients (17 women and 4 men with rheumatoid arthritis according to criteria of the American College of Rheumatology were enrolled in the study from September 2008 to July 2009 at Universidade Estadual de Campinas (UNICAMP. The average disease duration was 14 months. The patients were 66.6% Caucasians and 33.3% non-Caucasians, with a mean age of 42 and 41 years, respectively. A dorsal longitudinal scan was performed by ultrasound on the radiocarpal and midcarpal joints using GE LOGIQ XP-linear ultrasound and a high frequency (8-10 MHz transducer. All patients were X-rayed, and the Larsen score was determined for the joints, with grades ranging from 0 to V. This study showed significant correlations between clinical, sonographic and laboratory data: GSUS and swollen right wrist (r = 0.546, GSUS of right wrist and swelling of left wrist (r = 0.511, PDUS of right wrist and pain in left wrist (r = 0.436, PDUS of right wrist and C-reactive protein (r = 0.466. Ultrasound can be considered a useful tool in the diagnosis of synovitis in early rheumatoid arthritis mainly when the anti-cyclic citrullinated peptide and rheumatoid factor are negative, and can lead to an early change in the therapeutic decision.

Factors that influence fatigue status in patients with severe rheumatoid arthritis (RA) and good disease outcome following 6 months of TNF inhibitor therapy: a comparative analysis.

LENUS (Irish Health Repository)

Minnock, Patricia

2015-11-01

The objective of the present study is to determine the factors associated with persistent fatigue in patients with severe rheumatoid arthritis (RA) and good disease response to 6 months of tumour necrosis factor inhibitor therapy. Eligible patients with either persistent (PF) or no fatigue (NF) were compared. Using validated questionnaires and bivariate analysis, this cross-sectional survey explored if clinical characteristics, pain, self-efficacy, sleep and mood\\/depression differed between groups. Patients with PF (PF; NF) (n = 28; 28) reported significantly more overall pain (11.3 ± 9.4 (0-33); 6.9 ± 8.9 (0-33)), more recent and current pain intensity (41.4 ± 26.6 (0-80) 24.4 ± 26.6 (0-100) and depression (11.8 ± 7.5 (1-35); 8.2 ± 6.6 (0-26)), than the NF group. There was no significant difference between groups in self-efficacy and both groups experienced poor sleep quality (Pittsburgh Sleep Quality Index >5). Despite having good disease response, the PF group had significantly higher rheumatoid factor incidence, disease activity score-28, early morning stiffness duration and lower incidence of ever-failing disease-modifying anti-rheumatic drugs than the NF group. These findings enhance the fatigue literature in patients with RA prescribed tumour necrosis factor (TNF) inhibition therapy, identifying the potentially modifiable factors of pain and depression, previously demonstrated to be strongly associated with fatigue in non-biologic populations. In addition, this study highlights the association between persistent fatigue and an on-going state of low disease activity. This infers that more judicious disease management could minimise the symptom burden of pain and depression and consequentially fatigue.

2012-02-01

To investigate the role of interleukin (IL)-33 in rheumatoid arthritis (RA) patients, we measured the serum levels of IL-33 in RA patients before and after the administration of etanercept. Twenty-four patients with RA were treated with etanercept. Clinical and laboratory examinations, including serum levels of C-reactive protein (CRP) and hemoglobin (Hb); white blood cell (WBC) and red blood cell (RBC) counts; and the Disease Activity Score of 28 joints including CRP (DAS28-CRP), were performed at the baseline and at 3 and 6 months after the initial treatment with etanercept. The mean serum IL-33 levels had decreased significantly at 3 and 6 months after the initial treatment with etanercept. Serum IL-33 levels showed a significant correlation with the number of tender joints, CRP, DAS28-CRP, and the WBC count, and an inverse correlation with the RBC count and Hb level. These findings indicated that the decrease of serum IL-33 levels was a novel function of etanercept, shown for the first time in this study. Measurement of serum levels of IL-33 may become a useful control marker for RA treatment.

Cystic form of rheumatoid arthritis

Energy Technology Data Exchange (ETDEWEB)

Dijkstra, P.F.; Gubler, F.M.; Maas, A.

1988-10-01

A nonerosive form of rheumatoid arthritis (R.A.) was found in 62 patients out of 660 patients with R.A.. These 62 patients exhibit slowly progressive cystic changes in about the same joints in which usually erosions develop in classic R.A.. The E.S.R. is often low, half of the patients remained seronegative and there are 35 males and 27 females in the group. A smaller group of 15 out of these patients could be followed from a stage wherein the radiographs were normal to a stage of extensive cystic changes, over a period of at least 6 years. An attempt is made to delineate this group within the rheumatoid arthritis disease entity.

Full Text Available Although considered a “joint disease,” rheumatoid arthritis is associated with the involvement of extra-articular manifestations. The aim of the study is the investigation and comparison of frequency and type of extra-articular manifestations in a well defined community based cohort of patients with seropositive and seronegative rheumatoid arthritis. Using the ACR (1987 criteria for rheumatoid arthritis, patients have been classified into the 2nd and 3rd functional class (ARA. The studied group consisted of 125 seronegative patients with titters lower than 1:64 as defined by Rose-Waaler test, whereas the control group consisted of 125 seropositive patients with titters of 1:64 or higher. All patients were between 25-60 years of age (Xb=49,96, with disease duration between 1-27 years (Xb=6,41. In order to present the findings of the study, the structure, prevalence, arithmetic mean (Xb, standard deviation (SB, variation quotient (QV% and variation interval (Rmax-Rmin have been used. Probability level has been expressed by p<0,01 and p<0,05. Correlation between the number of extra-articular manifestations and duration of the disease has been calculated by means of Pearson linear correlation. Higher presence of diffuse lung fibrosis, central and peripheral nervous system damages have been confirmed in the seropositive group, and osteoporosis in the seronegative; however, no statistical difference has been found. In extra-articular manifestations, “rheumatoid core” in the seropositive subset (χ2=4,80, p<0,05 presented significant statistical difference. Rheumatoid nodules were more frequent in seropositive subset (12%:16%, in both sexes; however, they were not of significant statistical difference.

Full Text Available We have previously isolated several IgG rheumatoid factors (RFs from patients with both rheumatoid arthritis and idiopathic thrombocytopenia purpura using phage display system. To study IgG RFs in patients with other autoimmune diseases, phage display antibody libraries from a hepatitis C virus infected patient with Sjögren’s syndrome were constructed. After panning, a specific clone RFL11 was isolated for characterization in advance. The binding activity and specificity of RFL11 to IgG Fc fragment were comparable to those of RFs previously isolated. The analysis with existed RF-Fc complex structures indicated the homology model of RFL11 is similar to IgM RF61 complex with high binding affinity of about 6×10-8 M. This effect resulted from longer complementarity-determining region (CDR combining key somatic mutations. In the RFL11-Fc interfaces, the CDR-H3 loop forms a finger-like structure extending into the bottom of Fc pocket and resulting in strong ion and cation-pi interactions. Moreover, a process of antigen-driven maturation was proven by somatically mutated VH residues on H2 and H3 CDR loops in the interfaces. Taken together, these results suggested that high affinity IgG RFs can be generated in patients with Sjögren’s syndrome and may play an important role in the pathogenesis of this autoimmune disease.

Neutrophil Microvesicles from Healthy Control and Rheumatoid Arthritis Patients Prevent the Inflammatory Activation of Macrophages

Directory of Open Access Journals (Sweden)

Hefin I. Rhys

2018-03-01

Full Text Available Microvesicles (MVs are emerging as a novel means to enact cell-to-cell communication in inflammation. Here, we aimed to ascertain the ability of neutrophil-derived MVs to modulate target cell behaviour, the focus being the macrophage.MVs were generated in response to tumour necrosis factor-α, from healthy control neutrophils or those from rheumatoid arthritis patients. MVs were used to stimulate human monocyte-derived macrophages in vitro, or administered intra-articularly in the K/BxN mouse model of arthritis. A macrophage/fibroblast-like synoviocyte co-culture system was used to study the effects of vesicles on the crosstalk between these cells.We demonstrate a direct role for phosphatidylserine and annexin-A1 exposed by the MVs to counteract classical activation of the macrophages, and promote the release of transforming growth factor-β, respectively. Classically-activated macrophages exposed to neutrophil MVs no longer activated fibroblast-like synoviocytes in subsequent co-culture settings. Finally, intra-articular administration of neutrophil MVs from rheumatoid arthritis patients in arthritic mice affected the phenotype of joint macrophages.Altogether these data, with the identification of specific MV determinants, open new opportunities to modulate on-going inflammation in the synovia – mainly by affecting macrophage polarization and potentially also fibroblast-like synoviocytes - through the delivery of autologous or heterologous MVs produced from neutrophils.

Rheumatoid arthritis (RA) is the most common inflammatory rheumatic disease, affecting almost 1% of the world population. Although the cause of RA remains unknown, the complex interaction between immune mediators (cytokines and effector cells) is responsible for the joint damage that begins at the synovial membrane. Activated macrophages are critical in the pathogenesis of RA and showed specifically express a receptor for the vitamin folic acid (FA), folate receptor β (FRβ). This particular receptor allows internalization of FA-coupled cargo. In this review we will address the potential of nanoparticles as an effective drug delivery system for therapies that will directly target activated macrophages. Special attention will be given to stealth degree of the nanoparticles as a strategy to avoid clearance by macrophages of the mononuclear phagocytic system (MPS). This review summarizes the application of FA-target nanoparticles as drug delivery systems for RA and proposes prospective future directions. Rheumatoid arthritis is a debilitating autoimmune disease of the joints which affects many people worldwide. Up till now, there is a lack of optimal therapy against this disease. In this review article, the authors outlined in depth the current mechanism of disease for rheumatoid arthritis and described the latest research in using folic acid-targeted nanoparticles to target synovial macrophages in the fight against rheumatoid arthritis.

Our purpose is to study the roles of microRNA-338-5p (miR-338-5p) on the proliferation, invasion, and inflammatory response of fibroblast-like synoviocytes (SFs) in rheumatoid arthritis patients by regulating SPRY1. The target relationship between miR-338-5p and SPRY1 was validated through luciferase reporter system. The expression of miR-338-5p and SPRY1 in synovial tissues and synovial cells were detected using RT-PCR and western blot. The mimics and inhibitors of miR-338-5p were transfected into SFs. MTT, Transwell, and ELISA assays were used to analyze cell proliferation, invasiveness, and the secreted extracellular pro-inflammatory cytokines (such as IL-1a, IL-6, COX2) levels of SFs. MiR-338-5p was highly expressed in rheumatoid arthritis tissues and cells, and directly down-regulated the expression of SPRY1 in the SFs of rheumatoid arthritis patients. Cell proliferation, invasiveness and the expression level of pro-inflammatory cytokines in synovial cells increased after the transfection of miR-338-5p mimics, while the proliferation, invasion and expression level of pro-inflammatory cytokines decreased after the transfection of miR-338-5p inhibitors. In conclusion,miR-338-5p promoted the proliferation, invasion and inflammatory reaction in SFs of rheumatoid arthritis by directly down-regulating SPRY1 expression. J. Cell.

Mapuche, Chilean natives, represent approximately 9.8% of Chilean population and in the IX region of the country, they account for 18.4% of population over 15 years old. They preserve some socio-cultural characteristics that make them different to the rest of the population. To describe the epidemiological characteristics rheumatoid arthritis among Mapuche natives. Retrospective review of patients of Mapuche origin with rheumatoid arthritis, seen at Temuco Hospital between 1980 and 1996. Among 308 cases gathered, only 106 (93 women, aged 55 +/- 10 years old) complied with 1987 American College of Rheumatology (ACR) criteria for rheumatoid arthritis. The disease began between 29 and 52 years old in 73% of patients and the mean delay in diagnosis was 4.4 years. At diagnosis, 99% had symmetric poliarthritis, 28.3% had either fatigue, fever or weight loss, and 46.9% were in class III or in class IV of ACR-1991. Fifty three percent of patients developed Sicca syndrome, 36% developed nodules, 23% developed Raynaud phenomenon, 11% developed pulmonary involvement, 7% developed vasculitis, 5% developed neurological manifestations and 19% developed ophthalmologic involvement. Rheumatoid factor was positive in 78% and 73% had erosions. HLA DR4 was (+) in 60% of 30 patients. Thirty percent required 3 or more disease modifying drugs and prednisone over 10 mg/day. There was no correlation between functional capacity and several other features of the disease. Mapuche rheumatoid arthritis patients are detected late and have a poor functional capacity at the time of diagnosis. They also have a higher proportion of extraarticular manifestations, more erosions and require more aggressive treatments.

Full Text Available Abstract Background Foot deformities and related problems of the forefoot are very common in patients with rheumatoid arthritis. The laxity of the medial cuneometatarsal joint and its synovitis are important factors in the development of forefoot deformity. The impaired joint causes the first metatarsal bone to become unstable in the frontal and sagittal planes. In this retrospective study we evaluated data of patients with rheumatoid arthritis who underwent Lapidus procedure. We evaluated the role of the instability in a group of patients, focusing mainly on the clinical symptoms and X-ray signs of the instability. Methods The study group included 125 patients with rheumatoid arthritis. The indications of the Lapidus procedure were a hallux valgus deformity greater than 15 degrees and varus deformity of the first metatarsal bone with the intermetatarsal angle greater than 15 degrees on anterio-posterior weight-bearing X-ray. Results Data of 143 Lapidus procedures of 125 patients with rheumatoid arthritis, who underwent surgery between 2004 and 2010 was evaluated. Signs and symptoms of the first metatarsal bone instability was found in 92 feet (64.3% in our group. The AOFAS score was 48.6 before and 87.6 six months after the foot reconstruction. Nonunion of the medial cuneometatarsal joint arthrodesis on X-rays occurred in seven feet (4.9%. Conclusion The Lapidus procedure provides the possibility to correct the first metatarsal bone varus position and its instability, as well as providing the possibility to achieve a painless foot for walking. We recommend using the procedure as a preventive surgery in poorly symptomatic patients with rheumatoid arthritis in case of the first metatarsal bone hypermobility.

Rheumatoid patients may develop a retrodental lesion (atlantoaxial rheumatoid pannus) that may cause cervical instability and/or neurological compromise. The objective is to characterize clinical and radiographic outcomes after posterior instrumented fusion for atlantoaxial rheumatoid pannus. We retrospectively reviewed all patients who underwent posterior fusions for an atlantoaxial rheumatoid pannus at a single institution. Both preoperative and postoperative imaging was available for all patients. Anterior or circumferential operations, non-atlantoaxial panni, or prior C1-C2 operations were excluded. Primary outcome measures included Nurick score, Ranawat score (neurologic status in patients with rheumatoid arthritis), pannus regression, and reoperation. Pannus volume was determined with axial and sagittal views on both preoperative and postoperative radiological images. Thirty patients surgically managed for an atlantoaxial rheumatoid pannus were followed for a mean of 24.43 months. Nine patients underwent posterior instrumented fusion alone, while 21 patients underwent posterior decompression and instrumented fusion. Following a posterior instrumented fusion in all 30 patients, the pannus statistically significantly regressed by 44.44%, from a mean volume of 1.26cm(3) to 0.70cm(3) (ppannus radiographically regressed by 44.44% over a mean of 8.02 months, and patients clinically improved per the Nurick score. The Ranawat score did not improve, and 20% of patients required reoperation over a mean of 13.18 months. The annualized reoperation rate was approximately 13.62%. Copyright © 2015 Elsevier B.V.

Objective: to identify the most important and common comorbidities in patients with RA. Subjects and methods. Two hundred patients (median age 55 [46; 61] years were enrolled; there was a preponderance of women (82.5% with median disease duration 5 [1; 10] years, seropositive for IgM rheumatoid factor (83.0% and anti-cyclic citrullinated peptide antibodies (81.6% with moderate and high disease activity (median DAS28 value 3.9 [3.1; 4.9]. Varying degrees of destructive changes in hand and foot joints were radiologically detected in 71.2% of the patients; 64.5% of the patients had Functional Class II. Methotrexate was given to 69.5% of the patients; therapy with biological agents was used in 21.0% of the cases. 15.5% of the patients did not receive DMARD or biologics. 43.0% of the patients with RA received glucocorticoids. Results. Comorbidities were present in 72.0% of the patients with RA. The most common diseases were hypertension (60.0%, dyslipidemia (45.0%, fractures at various sites (29.5%, and coronary heart disease (21.0%. Myocardial infarction and stroke were observed in 1.5 and 1.0% of cases, respectively. There was diabetes mellitus (DM in 7.5% of the cases and osteoporosis in 15.5% of the patients. 81.7% of the patients with RA and hypertension and 80.0% of those with RA and DM received antihypertensive and sugar-lowering therapy, respectively. At the same time the RA patients with dyslipidemia and osteoporosis received specific drugs far less frequently (30.0 and 29.0%, respectively. Conclusion. Comorbidities are frequently encountered in RA. By taking into account the fact that cardiovascular dis- eases are a main cause of death in RA; it is necessary to adequately and timely

The aim of this study was to analyse the distribution of regulatory and inhibitory mothers against decapentaplegic homologue (Smad) proteins as markers of active transforming growth factor (TGF)-β signalling in rheumatoid arthritis (RA) synovial tissue and to investigate the effect of TGF-β blockade in the development and progression of collagen-induced arthritis. The expression of Smad proteins in synovial tissues from RA, osteoarthritic and healthy controls was analysed by immunohistochemistry. Arthritis was induced in DBA/1 mice by immunization with chicken type-II collagen (CII). TGF-β was blocked in vivo with the specific peptide p17 starting at the time of immunization or on the day of arthritis onset. T cell population frequencies and specific responses to CII were analysed. The expression of cytokines and transcription factors was quantified in spleen and joint samples. Statistical differences between groups were compared using the Mann-Whitney U-test or one-way analysis of variance (anova) using the Kruskal-Wallis test. p-Smad-2/3 and inhibitory Smad-7 expression were detected in RA and control tissues. In RA, most lymphoid infiltrating cells showed nuclear p-Smad-2/3 without Smad-7 expression. Treatment with TGF-β antagonist did not affect clinical severity, joint inflammation and cartilage damage in collagen-induced arthritis. Frequency of T cell subsets, mRNA levels of cytokines and transcription factors, specific proliferation to CII, serum interleukin (IL)-6 and anti-CII antibodies were comparable in p17 and phosphate-buffered saline (PBS)-treated groups. The pattern of Smad proteins expression demonstrates active TGF-β signalling in RA synovium. However, specific TGF-β blockade does not have a significant effect in the mice model of collagen-induced arthritis. © 2013 British Society for Immunology.

Rheumatoid arthritis (RA) and ankylosing spondylitis (AS) are common systemic autoimmune diseases with genetic and environmental predisposing factors. Signal transducer and activator of transcription 4 (STAT4) transmits signals induced by interleukin-12, interleukin-23 and interferon-γ, which are key cytokines and play important roles in the development of autoimmune diseases. Previous studies confirmed the STAT4 rs7574865 G/T locus to be associated with RA. Thus we conducted a replication study to investigate STAT4 rs7574865 G/T polymorphism and RA/AS susceptibility in a Chinese population. We studied STAT4 rs7574865 G/T gene polymorphism in 520 patients with RA, 100 AS patients and 520 controls in a Chinese population. Genotyping was done using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). When the STAT4 rs7574865 GG homozygote genotype was used as the reference group, the GT or GT/TT genotypes were associated with the risk for RA. After stratification analyses, a significantly increased risk for RA associated with the STAT4 rs7574865 GT genotype was evident among the rheumatoid factor (RF)-positive patients, patients with higher erythrocyte sedimentation rate (ESR) level and patients with higher RA disease activity score (DAS28) compared with the STAT4 rs7574865 GG genotype. A significantly increased risk for RA associated with the STAT4 rs7574865 TT genotype was evident among older patients and RF-negative patients compared with the STAT4 rs7574865 GG genotype. STAT4 rs7574865 G/T was not associated with susceptibility to AS. This replication study confirmed that STAT4 rs7574865 G/T polymorphism was associated with the risk of RA. STAT4 polymorphisms are associated with rheumatoid arthritis risk. Copyright © 2013 Elsevier B.V. All rights reserved.

Full Text Available Background: Rheumatoid Arthritis (RA is a chronic inflammatory disease presenting with inflammation, tenderness and destruction of the synovial joints, resulting in severe disability and early death due to complication of disease. Previous diagnostic criteria are not useful for identifying patients who need early treatment. Thus, new diagnostic criteria for faster diagnosis of disease are introduced in 2010. The aim of this study was to compared 1987 ACR (American College of Rheumatology criteria and 2010 ACR/EULAR (European League Against Rheumatism classification criteria for diagnosis of rheumatoid arthritis. Methods: In this Cohort prospective study, patients with early arthritis were evaluated   according to the old and new diagnostic criteria and followed-up every two monthly for one year (2012-2013 in Hazrat-e Rasool University Hospital, Tehran. Inclusion criteria of this study were age more than 18 year and indefinite diagnosis of arthritis. For all of patients physical examination by expert rheumatologist was done and lab data include erythrocyte sedimentation rate (ESR, C-reactive protein (CRP, anti-cyclic citrullinated peptide (Anti-CCP and rheumatoid factor was requested. The sensitivity, specificity, positive and negative predictive values were then determined for each diagnostic criteria. Results: In this study 104 patients including 28 males (26.9% and 76 females (73.1% with the mean age of 44.2±13.7 years were included. At the end of one year follow-up, 82 were diagnosed to have RA while other 22 patients were not categorized as RA. Sensitivity for ESR, CRP, Anti-CCP and rheumatoid factor in 2010 ACR/EULAR criteria was 52%, 19%, 48%, 28% and specificity for them was 45%, 71%, 27%, 79% respectively. Number of small and large joint arthritis were more in patients with Rheumatoid Arthritis (RA rather than other arthritis (P=0.0001. Sensitivity and specificity for small joints involvement was 87% and 54% and for large joints

Interstitial lung involvement in rheumatoid arthritis

Full Text Available Rheumatoid arthritis (RA is a systemic autoimmune rheumatic disease of unknown etiology, characterized by chronic erosive arthritis and extraarticular manifestations. Pulmonary involvement is one of the common extraarticular manifestations of RA and may show itself as bronchial tree lesions, rheumatoid nodules, Caplan's syndrome, and lesions in the pleura or pulmonary interstitium (interstitial lung involvement (ILI. High-resolution computed tomography allows the diagnosis of ILI in RA in nearly 70% of cases although the incidence of ILI may be lower (4 to 30% depending on diagnostic methods and patient selection criteria. There are several histopathological types of ILI, the differential diagnosis of which can be troublesome. Usual interstitial pneumonia (UIP and nonspecific interstitial pneumonia are major types of RA-associated ILI. UIP-pattern ILI has a more severe course than ILI with other histological patterns. The clinical presentation of ILI may be complicated by the likely toxic effect of a number of disease-modifying antirheumatic drugs (DMARDs used to treat RA, such as methotrexate and leflunomide, and biological agents (BAs, tumor necrosis factor-α (TNF-α inhibitors. The pathogenesis of pulmonary involvement in RA and the role of synthetic DMARDs and BAs in the development of ILI call for further investigations.An extraarticular manifestation, such as ILI, affects the choice of treatment policy in patients with RA.The relevance of a study of ILI is beyond question. The paper discusses the state-of-the-art of investigations in this area.

Biologic and oral disease-modifying antirheumatic drug monotherapy in rheumatoid arthritis

Emery, Paul; Sebba, Anthony; Huizinga, Tom W J

Clinical evidence demonstrates coadministration of tumour necrosis factor inhibitor (TNFi) agents and methotrexate (MTX) is more efficacious than administration of TNFi agents alone in patients with rheumatoid arthritis, leading to the perception that coadministration of MTX with all biologic agents or oral disease-modifying antirheumatic drugs is necessary for maximum efficacy. Real-life registry data reveal approximately one-third of patients taking biologic agents use them as monotherapy. Additionally, an analysis of healthcare claims data showed that when MTX was prescribed in conjunction with a biologic agent, as many as 58% of patients did not collect the MTX prescription. Given this discrepancy between perception and real life, we conducted a review of the peer-reviewed literature and rheumatology medical congress abstracts to determine whether data support biologic monotherapy as a treatment option for patients with rheumatoid arthritis. Our analysis suggests only for tocilizumab is there evidence that the efficacy of biologic monotherapy is comparable with combination therapy with MTX. PMID:23918035

Full Text Available A reduction in immunological parameters during therapy for rheumatoid arthritis (RA can yield new data on the mechanisms of anti-inflammatory action and be of great practical importance since this allows judgment of the depth of impact on the immunological process and therefore may be regarded as one of the components of improvement and remission. Objective: to study the effect of the tumor necrosis factor-a (TNF-а inhibitor adalimumab (ADA on a number of key immunological parameters in RA. Subjects and methods. The study included 100 patients (11 men and 89 women diagnosed with RA from 5 research centers. The patients were observed to have high RA activity: at baseline, DAS28 6.22+0.84 scores; C-reactive protein (CRP 37.1+34.7 mg/l. The mean number of disease-modifying antirheumatic drugs (DMARDs used by a patient in the history was 2.1. During 24-week treatment, the patients took ADA in a subcutaneous dose of 40 mg every 2 weeks both alone and in combination with DMARDs. The time course of changes in the serum levels of CRP, IGM rheumatoid factor (RF and in the concentration of anti-cyclic citrullinated peptide 2 (anti-CCP2 antibodies was determined by enzyme immunoassay (EIA using the Axis-Shield Diagnostics commercial kits (United Kingdom. The levels of TNF-a, interleukin (IL 6, 12, matrix metalloproteinase 3 (MMP3 were measured in pg/ml by EIA using the Bender MedSystems commercial kits (USA according to the manufacturer's directions. Results. During ADA therapy, there was a rapid reduction in the level of CRP from 34.3 to 11.317.2 mg/l following 2 weeks (p<0.001, which thereafter remained low (11.9 mg/l, with some fluctuations, until week 24 of the study. There was a significant reduction in blood RF levels from 169.24 to 111.97 at 24 weeks (p<0.001.

Evaluate the prevalence of sarcopenia on patients with rheumatoid arthritis (RA), the influence of sarcopenia on disease activity and factors associated with sarcopenia. One hundred and twenty-three patients aged over 18 years with RA based on the 1987 ACR/EULAR classification criteria were enrolled. We performed a whole body DXA scan using a dual-energy X-ray absorptiometry (DXA) scanner lunar prodigy to measure fat mass, lean mass, and bone mass in the whole body and body parts. According to the anthropometric equation by Baumgartner et al., sarcopenia was defined as Relative skeletal mass index (RSMI) sarcopenia with the r of Pearson and Spearman. Factors associated and related to sarcopenia were assessed using multiple regression analysis and t independent test. We included 123 patients (107 women). 49 subjects (39.8%) where suffering from sarcopenia, of which 40 women. Most of the sarcopenic patients were between 41 and 50 years old. Sarcopenia on female subjects was not related to parameters of disease activity evaluated by DAS 28, CDAI and SDAI. Most of the sarcopenic patients had normal BMI and abnormal waist circumference. In simple regression analysis sarcopenia was related to BMI, DAS 28 ESR, bone erosion, waist circumference and HAQ. In multiple regression analysis, sarcopenia was positively related to an increase cardiometabolic risk [p = 0.025, OR 0.176, CI (0.038-0.980)], normal BMI [p = 0.004, OR 12.3, CI (2.27-67.6)], over fat BMI [p = 0.004, OR 12.3, CI (2.27-67.6)] and bone erosion [p = 0.012, OR 0.057 CI (0.006-0.532)]. No statistical difference was found according to disease duration and steroids use between sarcopenic and non sarcopenic patients. Sarcopenia is prevalent and related to age, bone erosion, normal/over fat BMI and high cardiometabolic risk according to waist circumference but not with disease activity.

Full Text Available Angiopoietin-like protein 4 (ANGPTL4 is suggested to be a master regulator of plasma triglyceride metabolism. Our aim was to study whether the previously reported high levels of ANGPTL4 detected in serum from patients with rheumatoid arthritis (RA by ELISA was due to any specific molecular form of this protein (oligomers, monomers or fragments. ANGPTL4 levels were first determined in serum from 68 RA patients and 43 age and sex matched control subjects and the mean values differed by a factor of 5.0. Then, ANGPTL4 was analyzed after size exclusion chromatography (SEC of serum samples. With serum from one of the RA patients with high levels of ANGPTL4, the dominant reactivity was found in fractions corresponding to high-molecular weight proteins. In addition, a minor peak of reactivity eluting late from the column was found both in the patient and in controls. By the use of HeteroBlock®, and by careful selection of antibodies, we documented non-specific reactions for ANGPTL4 in 39% of samples from the RA patients, most likely due to cross-reactivity of the antibodies with rheumatoid factor (RF. The corresponding figure for control subjects was 6.3%. After corrections for non-specific reactions, the mean level of ANGPTL4 in serum from RA patients was still significantly higher than in control individuals (mean levels were 101±62 and 67±39 ng/ml respectively, P = 0.02. We re-analyzed samples from our previously published studies on ANGPL4 levels in patients on hemodialysis and patients with diabetes type 2. These samples did not show false positive reactions. The levels of ANGPTL4 were comparable to those detected previously.

2012-10-01

Rice body formation is a nonspecific response to chronic synovial inflammation associated with tuberculous arthritis, rheumatoid arthritis, juvenile rheumatoid arthritis, seronegative inflammatory arthritis, and even osteoarthritis. Such bodies were termed rice bodies because of their close resemblance to grains of polished white rice. We present a case report of a middle-aged woman with right shoulder subacromial/subdeltoid bursitis with giant rice body formation as her initial presentation of rheumatoid arthritis. Her right shoulder symptoms resolved after subacromial and subdeltoid bursectomy and removal of the rice bodies. She subsequently developed inflammatory arthritis of other joints, met the criteria for rheumatoid arthritis, and has been treated medically.

Brazilian epidemiological studies on rheumatoid arthritis are scarce, mainly in the northeast; thus many data currently available originate from the international literature. To describe demographic, clinical and serological characteristics of patients with rheumatoid arthritis (RA) followed-up by the same physician, in state of Piauí, Brazil. Data were collected between August 2010 and March 2013, in three health services of Piauí that provided health care in Rheumatology: a university-affiliated hospital, a public outpatient clinic and a private clinic. The numbers represent mean ± SD or percentage: 47.5±11.03 years-old non-Caucasian woman, non-smoker (59.2%), low educational level, mean disease duration of 7.7 years ± 7.6, and major extra-articular manifestations were rheumatoid nodules (19.4%) and sicca syndrome (46.9%). Features of rheumatoid arthritis obtained in this study are similar to those found in some national and international studies, but we observed higher female preponderance and illiteracy rate, in addition to a moderately severe erosive disease on average, with frequent sicca and other extra-articular manifestations.

Mruck, S.; Feistel, H.; Kat, S.; Kuwert, T.

2001-01-01

Radiosynovectomy is a therapeutic modality for local treatment of inflammatory point diseases. It is performed by intraarticular instillation of beta-emitting radionuclides. Its effectiveness is based upon the anti-inflammatory action of beta-radiation. Accordingly, the indication of radiosynovectomy is based upon the evidence of the inflammatory etiology of disease. The principle of its therapeutic action makes radiosynovectomy a valuable device for successful treatment of florid rheumatoid arthritis. It can be performed as an alternative to surgical synovectomy or in combination with it. The following article describes the therapeutic management of rheumatoid arthritis by radiosynovectomy including patient preparation, performance, and follow-up. (orig.) [de

Fibroblast-like synoviocytes derived from patients with rheumatoid arthritis play a key role by local production of cytokines and proteolytic enzymes that degrade the extracellular matrix and cartilage. These synoviocytes acquire phenotypic characteristics commonly observed in transformed cells, like anchorage-independent growth, increased proliferation and invasiveness, and insensitivity to apoptosis. Furin is a ubiquitous proprotein convertase that is capable of cleaving precursors of a wide variety of proteins. In patients with rheumatoid arthritis, furin is reported to be highly expressed in the synovial pannus compared with healthy persons. However, the mechanisms are poorly understood. This study is to explore the effect of furin overexpression in rheumatoid synoviocytes. In this study, RNA interference was used to knock down furin expression and to assess the resultant effects on biological behaviors of synoviocytes, such as cell proliferation, invasion, migration, cell cycle and cell apoptosis. In addition, the production of inflammatory cytokines was evaluated. The results showed that the inhibition of furin enhanced proliferation, invasion, and migration of synoviocytes in vitro. Cell cycle was accelerated and cell death was affected by furin knockdown. Also, the inhibition of furin increased interleukin-1β and tumor necrosis factor-α secretion of synoviocytes. Inhibition of furin enhances invasive phenotype of synoviocytes from patients with rheumatoid arthritis, implying a protective role of furin. Agents targeting upregulation of furin may have therapeutic potential for rheumatoid arthritis. Copyright © 2016 Société française de rhumatologie. Published by Elsevier SAS. All rights reserved.

BACKGROUND Rheumatoid arthritis is a chronic inflammatory disease with a substantial genetic component. Susceptibility to disease has been linked with a region on chromosome 2q. METHODS We tested single-nucleotide polymorphisms (SNPs) in and around 13 candidate genes within the previously linked chromosome 2q region for association with rheumatoid arthritis. We then performed fine mapping of the STAT1-STAT4 region in a total of 1620 case patients with established rheumatoid arthritis and 2635 controls, all from North America. Implicated SNPs were further tested in an independent case-control series of 1529 patients with early rheumatoid arthritis and 881 controls, all from Sweden, and in a total of 1039 case patients and 1248 controls from three series of patients with systemic lupus erythematosus. RESULTS A SNP haplotype in the third intron of STAT4 was associated with susceptibility to both rheumatoid arthritis and systemic lupus erythematosus. The minor alleles of the haplotype-defining SNPs were present in 27% of chromosomes of patients with established rheumatoid arthritis, as compared with 22% of those of controls (for the SNP rs7574865, P = 2.81×10-7; odds ratio for having the risk allele in chromosomes of patients vs. those of controls, 1.32). The association was replicated in Swedish patients with recent-onset rheumatoid arthritis (P = 0.02) and matched controls. The haplotype marked by rs7574865 was strongly associated with lupus, being present on 31% of chromosomes of case patients and 22% of those of controls (P = 1.87×10-9; odds ratio for having the risk allele in chromosomes of patients vs. those of controls, 1.55). Homozygosity of the risk allele, as compared with absence of the allele, was associated with a more than doubled risk for lupus and a 60% increased risk for rheumatoid arthritis. CONCLUSIONS A haplotype of STAT4 is associated with increased risk for both rheumatoid arthritis and systemic lupus erythematosus, suggesting a shared pathway

Objective: To determine frequencies of HLA DR beta 1 alleles in rheumatoid arthritis in Pakistani patients. Study Design: Cross sectional / analytical study. Place and Duration of Study: Department of Immunology, Armed Forces Institute of Pathology, Rawalpindi in collaboration with Rheumatology departments of Military Hospital, Rawalpindi and Fauji Foundation Hospital, Rawalpindi, from January 2009 to January 2010. Methodology: HLA DR beta 1 genotyping of one hundred Pakistani patients, diagnosed as having RA as per American College of Rheumatology revised criteria 1987, was done. HLA DR beta 1 genotyping was carried out at allele group level (DR beta 1*01-DR beta 1*16) by sequence specific primers in RA patients. Comparison of HLA DR beta 1 allele frequencies between patients and control groups was made using Pearson's chi-square test to find possible association of HLA DR?1 alleles with RA in Pakistani rheumatoid patients. Results: HLA DR beta 1*04 was expressed with significantly increased frequency in patients with rheumatoid arthritis (p <0.05). HLA DR?1*11 was expressed statistically significantly more in control group as compared to rheumatoid patients indicating a possible protective effect. There was no statistically significant difference observed in frequencies of HLA DR beta 1 allele *01, DR beta 1 allele *03, DR beta 1 allele *07, DR beta 1 allele *08, DR beta 1 allele *09, DR beta 1 allele *10, DR beta 1 allele *12, DR beta 1 allele *13, DR beta 1 allele *14, DR?1 allele *15 and DR beta 1 allele *16 between patients and control groups. Conclusion: The identification of susceptible HLA DR beta 1 alleles in Pakistani RA patients may help physicians to make early decisions regarding initiation of early intensive therapy with disease modifying anti rheumatic medicines and biological agents decreasing disability in RA patients.

We studied whether patients with seropositivity in early rheumatoid arthritis (RA) comprise a different clinical group than those with seronegativity. Four hundred seventeen patients with early RA according to the American College of Rheumatology criteria (disease duration less than 1 year) were retrospectively studied by analysis of demographic, clinical, laboratory, radiological, and therapeutic disease characteristics from the time of diagnosis until the end of the study period (1981 1999) using a data base. There were 248 seropositive patients and 169 seronegative patients with RA. No statistically significant differences were seen between the two groups before commencement of the study period in relation to age of disease onset, male:female ratio, and disease duration. However, seropositive patients showed longer medical follow-up. In addition, at disease onset, seropositive RA patients presented more frequently with symmetrical polyarthritis and small joint involvement than seronegative patients. The seropositive group also had more tender and swollen joints, weaker grip strength, and higher erythrocyte sedimentation and C-reactive protein rates during the follow-up period. In contrast, the seronegative group had less severe radiological findings and greater functional ability at the end of the study. In Greek patients with early RA, rheumatoid factor seems to be a predictor of more severe disease activity.

To evaluate the association of shared epitope, smoking and their interaction on the presence of autoantibodies (anti-cyclic citrullinated peptide [CCP] antibodies and rheumatoid factor) in patients with rheumatoid arthritis in our geographical area. A descriptive and cross-sectional study was carried out in a cohort of 106 patients diagnosed with RA. Odds ratios (OR) for antibody development were calculated for shared epitope, tobacco exposure and smoking dose. Statistical analysis was performed with univariate and multivariate statistics using ordinal logistic regression. Odds ratios were calculated with 95% confidence interval (95% CI) and a value of P20 packs/year) (OR=8.93; 95% CI: 1.95-40.82) were associated with the presence of anti-CCP antibodies. For rheumatoid factor, the association was only significant for tobacco exposure (OR=3.89; 95% CI: 1.06-14.28) and smoking dose (OR=8.33; 95% CI: 1.05-66.22). By ordinal logistic regression analysis, an association with high titers of anti-CCP (>200U/mL) was identified with South American mestizos, patients with homozygous shared epitope, positive FR and heavy smokers. Being a South American mestizo, having a shared epitope, rheumatoid factor positivity and a smoking dose>20 packs/year are independent risk factors for the development of rheumatoid arthritis with a high titer of anti-CCP (>200U/mL). In shared epitope-positive rheumatoid arthritis patients, the intensity of smoking is more strongly associated than tobacco exposure with an increased risk of positive anti-CCP.

Rheumatoid arthritis is an inflammatory synovial disease thought to involve T cells reacting to an antigen within the joint. Type II collagen is the major protein in articular cartilage and is a potential autoantigen in this disease. Oral tolerization to autoantigens suppresses animal models of T cell-mediated autoimmune disease, including two models of rheumatoid arthritis. In this randomized, double-blind trial involving 60 patients with severe, active rheumatoid arthritis, a decrease in the number of swollen joints and tender joints occurred in subjects fed chicken type II collagen for 3 months but not in those that received a placebo. Four patients in the collagen group had complete remission of the disease. No side effects were evident. These data demonstrate clinical efficacy of an oral tolerization approach for rheumatoid arthritis.

Fernanda Genre

Full Text Available Rheumatoid arthritis is an inflammatory disease with high incidence of cardiovascular disease due to accelerated atherosclerosis. Osteoprotegerin (OPG has been associated with increased risk of atherosclerotic disease in the general population. Several polymorphisms in the OPG gene with functional effects on cardiovascular disease in non-rheumatic individuals have been described. Therefore, we aimed to analyze the effect of three of these functional OPG polymorphisms on the risk of cardiovascular disease in a large and well-characterized cohort of Spanish patients with rheumatoid arthritis.Three OPG gene variants (rs3134063, rs2073618 and rs3134069 were genotyped by TaqMan assays in 2027 Spanish patients with rheumatoid arthritis. Anti-cyclic citrullinated peptide (anti-CCP antibody testing was positive in 997 of 1714 tested. Also, 18.3% of the whole series had experienced cardiovascular events, including 5.4% with cerebrovascular accidents. The relationship between OPG variants and cardiovascular events was assessed using Cox regression.No association between OPG gene variants and cardiovascular disease was observed in the whole group of rheumatoid arthritis patients or in anti-CCP positive patients. Nevertheless, a protective effect of CGA haplotype on the risk of cardiovascular disease in general, and specifically in the risk of cerebrovascular complications after adjusting for sex, age at disease diagnosis and traditional cardiovascular risk factors was disclosed in anti-CCP negative patients (HR = 0.54; 95%CI: 0.31-0.95; p = 0.032 and HR = 0.17; 95%CI: 0.04-0.78; p = 0.022, respectively.Our results indicate a protective effect of the OPG CGA haplotype on cardiovascular risk, mainly due to a protective effect against cerebrovascular events in anti-CCP negative rheumatoid arthritis patients.

LDL cholesterolemia as a novel risk factor for radiographic progression of rheumatoid arthritis: a single-center prospective study.

Directory of Open Access Journals (Sweden)

Yune-Jung Park

Full Text Available Dyslipidemia has been implicated in various musculoskeletal diseases, including rheumatoid arthritis (RA. Evidence is emerging that there might be a pathogenic interaction among inflammation, dyslipidemia, and adipokines. We prospectively investigated the association of cumulative lipid levels with radiographic progression of RA. RA patients (n=242 underwent plasma cholesterol assessment at four visits. Disease activity parameters and X-rays of the hands and feet were also serially monitored in these patients. The cumulative inflammatory burden and lipid levels were estimated by time-integrated values. Serum leptin and adiponectin concentrations were determined by ELISA. When patients were divided into three groups according to time-integrated lipid levels, as expected, patients with LDL cholesterol and/or triglyceride levels in the third tertile had persistently higher ESR and CRP levels. In parallel, a more rapid radiographic progression over two years was observed in patients with higher LDL cholesterol and/or triglyceride levels. In multivariate analysis, time-integrated LDL cholesterol was independently associated with radiographic progression. Particularly, the risk of radiographic progression was 5.6-fold in a subgroup with both LDL cholesterol and triglyceride levels in the third tertile. Moreover, LDL cholesterol synergistically increased the adjusted probability of radiographic progression in patients with high serum leptin levels but not in those without. These results demonstrate that LDL cholesterolemia is a novel serum marker that can be used to predict radiographic progression of RA, which seems to be related to circulatory leptin levels. We suggest that personalized and more aggressive anti-rheumatic therapy is required for dyslipidemic subgroups in RA patients.

Full Text Available Dry eye syndrome (DES is a common tear film and ocular surface disease that results in discomfort, visual disturbance, and tear film instability with potential damage to the ocular surface. Systemic diseases associated with DES include diabetes mellitus, rheumatoid arthritis, depression, anxiety, thyroid disease, allergic diseases, irritable bowel syndrome, chronic pain syndrome, and hyperlipidemia. Interestingly, it has been found that most of these are associated with low levels of serum 25-hydroxyvitamin D (25(OHD or inadequate sunlight exposure.In this cross-sectional data analysis, noninstitutionalized adults aged ≥19 years (N = 17,542 who participated in Korean National Health and Nutrition Examination Survey 2010-2012 were included. Information regarding duration of sunlight exposure was collected from the survey participants. Serum 25(OHD and zinc levels were measured. The confounding variables were age, gender, sunlight exposure time, region of residence, obesity, serum 25(OHD level, diabetes mellitus, rheumatoid arthritis, depression, thyroid disorder, atopic dermatitis, history of ocular surgery, regular exercise, and walking exercise.Mean serum 25(OHD levels of subjects with and without DES were 16.90 ± 6.0 and 17.52 ± 6.07 (p<0.001. Inadequate sunlight exposure time (odds ratio [OR], 1.554; 95% confidence interval [CI], 1.307-1.848, urban residence (OR, 1.669; 95% CI, 1.456-1.913, indoor occupation (OR, 1.578; 95% CI, 1.389-1.814, and low serum 25(OHD level (OR, 1.158; 95% CI, 1.026-1.308 were the risk factors for DES. After adjusting for age, sex, obesity, diabetes mellitus, rheumatoid arthritis, depression, thyroid disorder, atopic dermatitis, history of ocular surgery, regular exercise, and occupation, low serum 25(OHD level (OR, 1.178; 95% CI, 1.010-1.372 and deficient sunlight exposure time (OR, 1.383; 95% CI, 1.094-1.749 were the risk factors for diagnosed DES.Low serum 25(OHD levels and inadequate sunlight exposure are

Environmental and gene-environment interactions and risk of rheumatoid arthritis

Karlson, Elizabeth W.; Deane, Kevin

2012-01-01

Multiple environmental factors including hormones, dietary factors, infections and exposure to tobacco smoke as well as gene-environment interactions have been associated with increased risk for rheumatoid arthritis (RA). Importantly, the growing understanding of the prolonged period prior to the first onset of symptoms of RA suggests that these environmental and genetic factors are likely acting to drive the development of RA-related autoimmunity long before the appearance of the first joint symptoms and clinical findings that are characteristic of RA. Herein we will review these factors and interactions, especially those that have been investigated in a prospective fashion prior to the symptomatic onset of RA. We will also discuss how these factors may be explored in future study to further the understanding of the pathogenesis of RA, and ultimately perhaps develop preventive measures for this disease.

Objective was to study anti-bovine milk xanthine oxidoreductase XOPR antibody levels in synovial fluid as well as in serum of patients suffering from rheumatoid affections to assess a possible correlation between antibody titres and severity of disease. Sera and synovial fluids were collected from volunteer donors at Setif University Hospital, Setif, Algeria from 2001-2007 with the consent of patients. Human IgG and IgM levels of free and bound anti-bovine milk XOR antibodies were determined using bovine XOR as antigen, with enzyme-linked immunosorbent assay ELISA. Serum IgG anti-bovine milk XOR titres in 30 healthy normal subjects 2.74+-2.31 microgram/mL are in agreement with that reported in the literature. Immunoglobulin G and IgM anti-bovine milk XOR antibody titres were found to be significantly higher in serum from patients with rheumatoid arthritis RA and latex positives subjects. Synovial IgM antibody titres to bovine XOR were found to be significantly higher in rheumatoid arthritis patients compared to patients with other joint inflammations. In rheumatoid arthritis patients, high concentrations of antibodies against XOR were noticed. These antibodies may play a major role in RA by inhibiting both xanthine and NADH oxidase activities of XOR. They may also play a key role in eliminating XOR from serum and synovial fluid positive role but unfortunately, immune complex formation could also activate complement and participate in self maintenance of inflammation.

Full Text Available Objective. To characterize specters of common and modified lipoproteins (LP in serum of pts with rheumatoid arthritis (RA according to age and sex and compare with healthy donors (with normal lipid level. Material and methods. 103 pts with RA (88 female and 15 male aged 21 to 69 years were included. Specters of common and modified LP in serum and plasma were evaluated with small-angle x-ray scattering. Results. Low level of intermediate density lipoproteins (IDLP subfractions and very low density lipoproteins (VLDLP as well as high level of low density lipoproteins (LDLP30 was revealed in pts with RA. Mean level of LP modification was about 60%. High density lipoproteins (HDLP subfraction was least and IDLP subfraction – most susceptible to modification. LP modification level increased due to LDLP and VLDLP fractions. This level had a tendency to increase with age because of elevation of atherogenic LP part. Mean values of common LP did not differ between sex and age groups of pts with RA. Unexpectedly low (in comparison with normal lipid content level of LP modification of the whole fraction of HDLP was the feature of modified LP specter in pts with RA. Conclusion. Level of common and modified LP in blood plasma and serum of RA pts is connected with general state of lipid metabolism and immune defense factors balance. Low level of VLDLP cholesterol and high level of LDLP cholesterol as well as high degree of LP of these fractions modification may be probably considered as markers of RA activity.

Diagnostic opportunities of scintigraphy with sup(113m)In- eluate in 49 rheumatoid arthritis patients with prevalent knee joint affections at the exudative-proliferative period of the disease have been studied. Selective accumulation of radionuclide in the inflammatory tissue forms the basis of the method. It is shown that the scintigraphic study (scintiscanning) with sup(113m)In allows to differentiate between the exudative ad exudative-proliferative stages of rheumatoid arthritis and to assess the results of medicamentary treatment

The analysis of gene expression data shows that many genes display similarity in their expression profiles suggesting some co-regulation. Here, we investigated the co-expression patterns in gene expression data and proposed a correlation-based research method to stratify individuals. Using blood from rheumatoid arthritis (RA) patients, we investigated the gene expression profiles from whole blood using Affymetrix microarray technology. Co-expressed genes were analyzed by a biclustering method, followed by gene ontology analysis of the relevant biclusters. Taking the type I interferon (IFN) pathway as an example, a classification algorithm was developed from the 102 RA patients and extended to 10 systemic lupus erythematosus (SLE) patients and 100 healthy volunteers to further characterize individuals. We developed a correlation-based algorithm referred to as Classification Algorithm Based on a Biological Signature (CABS), an alternative to other approaches focused specifically on the expression levels. This algorithm applied to the expression of 35 IFN-related genes showed that the IFN signature presented a heterogeneous expression between RA, SLE and healthy controls which could reflect the level of global IFN signature activation. Moreover, the monitoring of the IFN-related genes during the anti-TNF treatment identified changes in type I IFN gene activity induced in RA patients. In conclusion, we have proposed an original method to analyze genes sharing an expression pattern and a biological function showing that the activation levels of a biological signature could be characterized by its overall state of correlation.

2009-01-01

The introduction of disease-modifying antirheumatic drugs has created new demands on imaging to early identify patients with rheumatoid arthritis and opened new prospects in therapeutic management of patients with aggressive disease. Therefore, new imaging modalities such as magnetic resonance imaging and ultrasound have developed during the past few years in this field. In some cases, both magnetic resonance imaging and ultrasound may be also useful in making the distinction between early rheumatoid arthritis and other joints abnormalities, including early psoriatic arthritis. This article will review key aspects of important advances in imaging in rheumatoid arthritis, particularly focusing on magnetic resonance imaging and ultrasound.

Power Doppler sonography and ultrasound contrast agent in assessing rheumatoid synovitis

F. Salaffi

2011-09-01

Full Text Available Pannus formation is a fundamental event in the pathogenesis of rheumatoid arthritis and its hypervascularisation seems to be crucial to the development of joint damage. High-resolution greyscale ultrasonography is a safe, quick, and inexpensive imaging tool that allows an accurate detection of even minimal morphostructural changes in patients with rheumatoid arthritis, including joint effusion, thickening of synovial membrane and bone erosions. More recently, power Doppler sonography has proved to be a reliable tool for semiquantitative assessment of the vascularity of the synovial tissue. The contrast-enhanced power Doppler sonography seems to be a helpful adjunct in assessing synovitis and the therapeutic response to the different therapies in patients with rheumatoid arthritis. The aim of this radiological vignette was to show a representative example of use of power Doppler sonography with contrast agent in assessing rheumatoid synovitis.

Full Text Available Background. Rheumatoid arthritis (RA, met in the literature also as chronic evolving polyarthritis, is a chronic inflammatory disease, which typically involves the small and medium joints, with a symmetric distribution. Clinical studies shown that a proportion of patients with RA, without measurable rheumatoid factors are a distinct entity from those patients with seropositive RA. Around one third of patients with RA are seronegative for those two serological markers, the rheumatoid factors (RF and anti-citrullinated peptide antibodies (Anti-CCP. Hands are the most frequently affected in both seropositive and seronegative RA and the first joints involved in the inflammatory process are the metacarpo-phalangeal joints, IFP joints and the radiocarpian joint. The big joints become later symptomatic, after the small joints are affected. Materials and methods: 66 patients files and the personal records of the patients consecutively admitted in the Rheumatology Department of the Clinical Emergency County Hospital Constanta. Patients from county Constanta were included in the study, with diagnosis of rheumatoid arthritis (diagnosis confirmed at least 2 years ago, including both forms (seropositive and seronegative of the disease. The complete clinical exam was done for the patients included in the study, following the identification of the active joint disease. The mechanical status of the joint was observed by a single evaluator for each of those 66 patients with RA, with special focus on the presence of the deformities / ankyloses of the hands joints. Therefore, there were evaluated: the mobility (the number of the joints with limited movements, deformities, ankyloses (the number of the joints without mobility. The joint mobility was assessed by counting the hand joints with limited movements and the worsening of the prehension function. The presence of the following hand deformities was followed: fingers in “swan neck”, “fusiform fingers�

Dijkstra, P.F.; Gubler, F.M.; Maas, A.

1988-01-01

A nonerosive form of rheumatoid arthritis (R.A.) was found in 62 patients out of 660 patients with R.A.. These 62 patients exhibit slowly progressive cystic changes in about the same joints in which usually erosions develop in classic R.A.. The E.S.R. is often low, half of the patients remained seronegative and there are 35 males and 27 females in the group. A smaller group of 15 out of these patients could be followed from a stage wherein the radiographs were normal to a stage of extensive cystic changes, over a period of at least 6 years. An attempt is made to delineate this group within the rheumatoid arthritis disease entity. (orig.) [de

Central nervous system (CNS) involvement by rheumatoid arthritis (RA) in the form of rheumatoid meningitis (RM) is rare and most commonly occurs in the setting of longstanding severe RA. Due to a wide range of clinical presentations and nonspecific laboratory findings, it presents a diagnostic challenge often requiring brain biopsy. Only a few histopathologically confirmed cases have been described in the literature. Our aim is to describe two cases of RM and review the literature. The first case is of a previously healthy 37-year-old man who presented with severe headaches and focal neurologic deficits. Magnetic resonance imaging demonstrated abnormal leptomeningeal enhancement in the left frontal and parietal sulci. The second case is of a 62-year-old woman with a history of mild chronic joint pain who presented with confusion, personality changes and seizures. Both patients ultimately underwent brain biopsy which demonstrated RM on pathologic examination. Administration of corticosteroids resulted in significant clinical improvement in both cases. To our knowledge, our unusual case of RM in the young man is the fifth reported case of rheumatoid meningitis in a patient with no prior history of RA. Such an atypical presentation makes diagnosis even more difficult and highlights the need for awareness of this entity in the diagnostic consideration of a patient presenting with unexplained neurologic symptoms. Our literature review underscores the clinical and pathologic heterogeneity of CNS involvement in RA. © 2015 Japanese Society of Neuropathology.

Rheumatoid arthritis is the most common inflammatory rheumatic disease. Due to the destruction of joints in the course of the disease it leads to significant morbidity in affected patients. The quality of life and even life expectancy can be severely impaired. Early diagnosis and early initiation of treatment is a decisive step towards a more benign course of the disease. New classification criteria have been published in order to help in early diagnosis. Methods of imaging, such as ultrasound and magnetic resonance imaging help in the detection of synovitis, which is the major pathomorphological manifestation of arthritis and should be identified without any doubt. Treatment follows the rule of treat to target with the aim of achieving remission or if this is not realistic, at least the lowest possible level of disease activity. The first and perhaps most important step in therapy is the initiation of methotrexate or if contraindications are present, another disease-modifying antirheumatic drug (DMARD) as soon as the diagnosis is made. Initial addition of glucocorticoids is recommended, which should be reduced in dose and terminated as soon as possible. Furthermore, either the combination of different DMARDs or the start of biologic DMARDs, such as tumor necrosis factor alpha (TNF-alpha) inhibitors or second generation biologic DMARDs is possible as a treatment option. The treatment follows the rule of shared decision-making and is the standard to treat comorbidities, the use an interdisciplinary approach and to treat functional deficits by rehabilitation measures, such as physiotherapy.

To determine the effect of disclosure of rheumatoid arthritis (RA) risk personalized with genetics, biomarkers, and lifestyle factors on health behavior intentions. We performed a randomized controlled trial among first-degree relatives without RA. Subjects assigned to the Personalized Risk Estimator for Rheumatoid Arthritis (PRE-RA) group received the web-based PRE-RA tool for RA risk factor education and disclosure of personalized RA risk estimates, including genotype/autoantibody results and behaviors (n = 158). Subjects assigned to the comparison arm received standard RA education (n = 80). The primary outcome was readiness for change based on the trans-theoretical model, using validated contemplation ladder scales. Increased motivation to improve RA risk-related behaviors (smoking, diet, exercise, or dental hygiene) was defined as an increase in any ladder score compared to baseline, assessed immediately, 6 weeks, and 6 months post-intervention. Subjects reported behavior change at each visit. We performed intent-to-treat analyses using generalized estimating equations for the binary outcome. Subjects randomized to PRE-RA were more likely to increase ladder scores over post-intervention assessments (relative risk 1.23, 95% confidence interval [95% CI] 1.01, 1.51) than those randomized to nonpersonalized education. At 6 months, 63.9% of PRE-RA subjects and 50.0% of comparison subjects increased motivation to improve behaviors (age-adjusted difference 15.8%; 95% CI 2.8%, 28.8%). Compared to nonpersonalized education, more PRE-RA subjects increased fish intake (45.0% versus 22.1%; P = 0.005), brushed more frequently (40.7% versus 22.9%; P = 0.01), flossed more frequently (55.7% versus 34.8%; P = 0.004), and quit smoking (62.5% versus 0.0% among 11 smokers; P = 0.18). Disclosure of RA risk personalized with genotype/biomarker results and behaviors increased motivation to improve RA risk-related behaviors. Personalized medicine approaches may motivate health

2011-01-01

To investigate the experiences and needs with respect to work participation of employees with rheumatoid arthritis (RA) treated with anti-tumour necrosis factor (TNF) therapy. Face-to-face interviews in 14 employees with RA on anti-TNF therapy focused on experiences, offered support and needs with respect to work participation. Experiences regarding work participation varied and ranged from fatigue at work, having no job control, not being understood by the work environment or difficulty dealing with emotions as a result of interaction within the work environment. Support by health care professionals for work participation was considered important, especially concerning social or psychological issues. Advice in becoming aware of one's changes in abilities was highly appreciated, as was the availability of professional advice in times of an urgent work issue due to RA. Employees mentioned an increase in social support at work and job control as important facilitating factors for work participation. Although patients with RA report improvement in their work functioning after starting anti-TNF therapy, employees continue facing challenges in working life due to RA. For support concerning work participation, it is recommended that health care professionals are more aware of work-related problems in patients with RA treated with anti-TNF therapy.

Full Text Available Objectives. To explore the correlation of serum IgG4 (sIgG4 with clinical manifestations or therapeutic response in rheumatoid arthritis (RA. Methods. Consecutive 136 RA patients were recruited and followed up at regular interval. SIgG4 was detected by immunonephelometry. Serial synovial tissue sections from 46 RA patients were stained immunohistochemically for IgG4. Results. Forty-six percent of 136 RA patients had elevated sIgG4. Patients with elevated sIgG4 had higher sIgG4/sIgG ratio, C-reactive protein, erythrocyte sedimentation rate, rheumatoid factor, and anticyclic citrullinated peptide antibodies than those with normal sIgG4 (all P<0.05. Among 45 patients who received methotrexate and leflunomide therapy, 50% (9/18 of patients with elevated sIgG4 and 85% (23/27 of patients with normal sIgG4 reached therapeutic target (disease activity score of 28 joints < 3.2 at 6-month visit (χ2=6.508, P=0.011. IgG4-positive plasma cell count correlated positively with sIgG4, total synovitis score, and CD3-, CD20-, and CD38-positive cell counts (all P<0.05. Conclusions. Our results showed that elevated sIgG4 in RA is common and disproportional to total IgG and RA with elevated sIgG4 may be a specific clinical phenotype with higher disease activity, higher level of autoantibodies, and poor response to methotrexate and leflunomide therapy.

Foot pain is common in rheumatoid arthritis and appears to persist despite modern day medical management. Several clinical practice guidelines currently recommend the use of foot orthoses for the treatment of foot pain in people with rheumatoid arthritis. However, an evidence gap currently exists concerning the comparative clinical- and cost-effectiveness of prefabricated and customised foot orthoses in people with early rheumatoid arthritis. Early intervention with orthotics may offer the best opportunity for positive therapeutic outcomes. The primary aim of this study is to evaluate the comparative clinical- and cost-effectiveness of prefabricated versus customised orthoses for reducing foot pain over 12 months. This is a multi-centre two-arm parallel randomised controlled trial comparing prefabricated versus customised orthoses in participants with early rheumatoid arthritis (rheumatoid arthritis, global functional status via the Stanford Health Assessment Questionnaire, foot disease activity via the Rheumatoid Arthritis Foot Disease Activity Index, and health-related quality of life at baseline, 6 and 12 months. Process outcomes will include recruitment/retention rates, data completion rates, intervention adherence rates, and participant intervention and trial participation satisfaction. Cost-utility and cost-effectiveness analyses will be undertaken. Outcome measures collected at baseline, 6 and 12 months will be used to evaluate the comparative clinical- and cost- effectiveness of customised versus prefabricated orthoses for this treatment of early rheumatoid arthritis foot conditions. This trial will help to guide orthotic prescription recommendations for the management of foot pain for people with early rheumatoid arthritis in future. ISRCTN13654421. Registered 09 February 2016.

Full Text Available Objective: To ascertain a relationship between Toxoplasma gondii (T. gondii infection and rheumatoid arthritis (RA disease among Egyptian patients. Methods: One hundred RA patients and 50 healthy subjects participated in this study. The patients were classified into three groups, namely GI, G2 and G3. Patients in G1 were recently diagnosed with RA with the disease duration of less than one year (prior treatment; G2 included RA patients receiving anti-tumor necrosis factor agents and RA patients in G3 received disease modifying anti-rheumatic drugs (methotrexate, antimalarial, corticosteroids. Serum samples of all participants were examined for the presence of anti-Toxoplasma immunoglobulin G (IgG antibodies and positive samples were further analyzed for antiToxoplasma IgM antibodies to detect the possibility of reactivation of latent toxoplasmosis. Also, the association between Toxoplasma seropositivity and clinical, laboratory and radiological features of these patients were determined. Results: There was a significantly higher percentage of T. gondii IgG positivity in RA patients (54% than in the controls (32%. At the same time, 20.40% of T. gondii IgG positive patients had anti-T. gondii IgM antibodies with a statistically significant difference as comparing to T. gondii IgG positive controls. Out of T. gondii seropositive patients, 20.37% had a lower IgG level with a mean titer of (65.3 ± 17.7 IU/mL, 46.29% had moderate level with a mean titer of (184.2 ± 60.0 IU/mL and 33.33% had higher level with a mean titer of (404.3 ± 50.0 IU/ mL. A positive correlation was found between disease activity and Toxoplasma seropositivity. T. gondii seropositive RA patients had longer disease duration, longer time morning stiffness, higher numbers of tender and swollen joints and also increase in disease severity markers (erythrocyte sedimentation rate, C-reactive protein, disease activity score 28, anti-cyclic citrullinated peptide anti

Background Rehabilitation approaches for people with rheumatoid arthritis include joint protection, exercises and self-management strategies. Health interventions delivered via the web have the potential to improve access to health services overcoming time constraints, physical limitations, and socioeconomic and geographic barriers. The objective of this review is to determine the effects of web-based rehabilitation interventions in adults with rheumatoid arthritis. Methods Randomised controlled trials that compared web-based rehabilitation interventions with usual care, waiting list, no treatment or another web-based intervention in adults with rheumatoid arthritis were included. The outcomes were pain, function, quality of life, self-efficacy, rheumatoid arthritis knowledge, physical activity and adverse effects. Methodological quality was assessed using the Cochrane Risk of Bias tool and quality of evidence with the Grading of Recommendations Assessment, Development and Evaluation approach. Results Six source documents from four trials ( n = 567) focusing on self-management, health information or physical activity were identified. The effects of web-based rehabilitation interventions on pain, function, quality of life, self-efficacy, rheumatoid arthritis knowledge and physical activity are uncertain because of the very low quality of evidence mostly from small single trials. Adverse effects were not reported. Conclusion Large, well-designed trials are needed to evaluate the clinical and cost-effectiveness of web-based rehabilitation interventions in rheumatoid arthritis.

Full Text Available Controversial observations have been published on the association of the cytotoxic T lymphocyte associated antigen gene's variants with rheumatoid arthritis (RA. After genotyping 428 patients and 230 matched controls, the prevalence of the CT60∗G allele was more frequent in RF- and/or anti-CCP-seropositive RApatients, compared to the healthy controls (P<.001. Regression analysis revealed that the CT60∗G allele is a possible predisposing factor for RA in these subgroups. No accumulation of the +49∗G allele was found among patients, and this variant was not found to correlate with RA. Assaying the possible genotype variations, the +49∗G-CT60∗G allelic combination was accumulated in seropositive RA-subtypes, and was associated with the risk of RA (OR=1.73, P=.001 for the whole RA-population. Although the +49∗G allele did not mean a predisposition to RA alone, in combination with CT60∗G it, also conferred risk, suggesting that the +49A/G variant is associated with the risk of RA only in certain haplotypes.

Rheumatoid arthritis is an autoimmune arthritis in which two inflammatory cytokines, tumor necrosis factor-α and interleukin-1β, play a critical role in the induction and progression of the disease. Several reports and data from registries have discussed the association between chronic inflammatory diseases and disorders in intermediary metabolism, pointing out that prevalence of peripheral insulin resistance and type 2 diabetes mellitus is increased among patients with rheumatoid arthritis. In addition, several studies have shown that type 2 diabetes mellitus may be considered an interleukin-1β inflammatory-mediated process, and both preclinical and clinical observations have reported the usefulness of interleukin-1 antagonism therapy in this disease. We describe the case of a 58-year-old Caucasian woman and a 74-year-old Caucasian man with rheumatoid arthritis associated with type 2 diabetes mellitus. In these patients, the inhibition of interleukin-1β not only induced remission for rheumatoid arthritis, but successfully controlled their metabolic status. We report the positive effects of the inhibition of interleukin-1 in two patients with rheumatoid arthritis associated with type 2 diabetes mellitus, with both reaching the therapeutic targets of their diseases by using a single biological agent and tapering or discontinuing their antidiabetic therapies. These findings suggest that targeting interleukin-1 might be considered a good therapeutic option for the treatment of rheumatoid arthritis associated with type 2 diabetes mellitus.

Rheumatoid arthritis is the commonest inflammatory joint disease, affecting nearly 1% of the adult population worldwide. Early and accurate diagnosis and prognosis of rheumatoid arthritis (RA) have become increasingly important. In the present study, we aimed to elucidate the relationships between hematological, biochemical, immunological and cytogenetic parameters in rheumatoid arthritis patients and healthy normal controls. The study group comprised of 126 RA patients and equal number of healthy normal control subjects. The blood was collected and analyzed for biochemical, immunological, enzymatic and cytogenetic parameters. Results of the present study indicated that 20% of RA patient's hematological, 31% of biochemical and 70% immunological parameters had a significant difference from the controls and reference range. The RF and anti-CCP antibody levels were also positive in 70% of RA patients. A significant increase in minor chromosomal abnormalities was also observed in patients as compared to controls. The knowledge about autoimmune diseases is very low among the South Indian population. The present study has thus helped in understanding the RA disease in a better way based on a pattern of various clinical markers of the disease condition which might help in planning therapeutic intervention strategies and create awareness about the disease management among RA patients of the population studied.

Serum levels of calprotectin, a major S100 leucocyte protein, are associated with disease activity in rheumatoid arthritis (RA) and psoriatic arthritis (PsA) patients. Higher drug trough serum levels are associated with good response in patients treated with tumour necrosis factor inhibitors (TNFi). Power Doppler ultrasound (PDUS) synovitis is predictive of flare and progression of structural damage in patients in clinical remission. The purpose of this study was to analyse the accuracy of calprotectin and TNFi trough serum levels in detecting PDUS synovitis in RA and PsA patients in clinical remission or with low disease activity who were receiving TNFi. We conducted a cross-sectional study of 92 patients (42 with RA, 50 with PsA) receiving adalimumab (ADA), etanercept (ETN) or infliximab who were in remission or had low disease activity (28-joint Disease Activity Score based on erythrocyte sedimentation rate ultrasound scores (all r coefficients >0.50 in RA). Calprotectin correlated with the PDUS synovitis score in patients treated with ADA and ETN. Using PDUS synovitis (yes or no) as the reference variable, calprotectin had an AUC of 0.826. The best cut-off was ≥1.66 μg/ml, with a likelihood ratio of 2.77. C-reactive protein (AUC 0.673) and erythrocyte sedimentation rate (AUC 0.731) had a lower discriminatory capacity. TNFi trough serum levels were significantly associated with PDUS synovitis (OR 0.67, 95 % CI 0.52-0.85, p < 0.001) but their accuracy (AUC <0.5) was less than that of calprotectin. TNFi trough serum levels were inversely correlated with calprotectin and PDUS synovitis in RA and PsA patients receiving ADA and ETN. Calprotectin and TNFi trough serum levels may help identify PDUS synovitis in RA and PsA patients in clinical remission or with low disease activity.

RITUXIMAB: NEW POTENTIALITIES OF THERAPY FOR RHEUMATOID ARTHRITIS

Full Text Available Some patients with rheumatoid arthritis (RA are unresponsive or intolerant to both synthetic first-line anti-inflammatory drugs (FLAID and tumor necrosis factor (TNF а inhibitors already included into all the treatment standards . Along with the conventional methods for overcoming drug resistance - switching to another FLAID or another TNF а blocker, the use of biologicals with another mechanism of action rather than suppression of TNF а gives a good account of itself. Prominent among these agents is the anti-B-cell drug rituximab. The new possibilities of the therapy, which open up the use of rituximab in patients with RA, are discussed.

Background Periodontitis has been regarded as a potential risk factor for rheumatoid arthritis (RA). A systematic review is made to determine whether nonsurgical periodontal treatment in patients with RA offers benefits in terms of the clinical activity and inflammatory markers of the disease. Material and Methods A search was made of the Medline-PubMed, Cochrane, Embase and Scopus databases to identify studies on the relationship between the two disease processes, and especially on the effects of nonsurgical treatment in patients of this kind. The search was based on the following keywords: rheumatoid arthritis AND periodontitis (MeSH), rheumatoid arthritis AND periodontal treatment. Results Eight articles on the nonsurgical treatment of patients with periodontitis and RA were finally included in the study. All of them evaluated clinical (DAS28) and laboratory test activity (ESR, CRP, IL-6, TNFα) before and after treatment. A clear decrease in DAS28 score and ESR was recorded, while other parameters such as CRP, IL-6 and TNFα showed a non significant tendency to decrease as a result of treatment. Conclusions Nonsurgical treatment improved the periodontal condition of patients with periodontitis and RA, with beneficial effects upon the clinical and laboratory test parameters (DAS28 and ESR), while other inflammatory markers showed a marked tendency to decrease. However, all the studies included in the review involved small samples sizes and follow-up periods of no more than 6 months. Larger and particularly longitudinal studies are therefore needed to more firmly establish possible significant relations between the two disease processes.

Ghrelin is a newly characterised growth hormone (GH) releasing peptide widely distributed that may play an important role in the regulation of metabolic balance in inflammatory diseases such as rheumatoid arthritis (RA) by decreasing the pro-inflammatory Th1 responses. In this study we investigated the possible contribution of several polymorphisms in the functional Ghrelin receptor to RA susceptibility. A screening of 3 single nucleotide polymorphisms (SNPs) was performed in a total of 950 RA patients and 990 healthy controls of Spanish Caucasian origin. Genotyping of all 3 SNPs was performed by real-time polymerase chain reaction technology, using the TaqMan 5'-allele discrimination assay. We observed no statistically significant deviation between RA patients and controls for the GHSR SNPs analysed. In addition, we performed a haplotype analysis that did not reveal an association with RA susceptibility. The stratification analysis for the presence of shared epitope (SE), rheumatoid factor (RF) or antibodies anti cyclic citrullinated peptide (anti-CCP) did not detect significant association of the GHSR polymorphisms with RA. These findings suggest that the GHSR gene polymorphisms do not appear to play a major role in RA genetic predisposition in our population.

Bhattacharya, N

2006-01-01

Rheumatoid arthritis is the commonest form of inflammatory arthritis and affects about 1-3% of the population in the West and even more in the developing world due to the compounded factors of late detection and inadequate treatment in the overall background of poverty, deprivation, and improper macro and micronutrients in the diet in a sizeable segment of the population. Nearly 90% of patients with aggressive disease will become clinically disabled within 20 years. Furthermore, in patients with severe disease or extra-articular symptoms, mortality is equal to that for patients with triple artery coronary artery disease or Stage IV Hodgkin's lymphoma. Anemia is a very common comorbidity of rheumatoid arthritis. Anemia in rheumatoid arthritis is caused by various factors, for instance, cytokine impact of the advanced arthritic process on the host, or lack of proper nutrition and essential micronutrients in the diet, or coexistent helminthiasis, and/or impact of antiarthritic drugs on the host system, i.e., high steroid induced gastritis or ulcerations in gastric mucosa or subclinical or clinical hepatitis due to methotrexate or salazopyrin effects on bone marrow, only to name a few. Other pre-existing or compounding gastrointestinal problems, which alter the available iron stores or cause bone marrow dysfunction, may also help in adding to an anemic condition. If the anemia is 8 g/dl or less, blood transfusion or erythropoietin injection with adequate hematinic reserve is effective in normal situations, but is not that effective in anemia with a chronic disease background like rheumatoid arthritis. Cord blood, because of its rich mix of fetal and adult hemoglobin, high platelet and white blood cell (WBC) counts, and a plasma filled with cytokine and growth factors, as well as its hypo antigenic nature and altered metabolic profile, has all the potential of a real and safe alternative to adult blood transfusion.

Full Text Available The detection of anti-cyclic citrullinated peptide (anti-CCP antibodies plays a diagnostic and statistical predictive role in rheumatoid arthritis (RA. The decreased concentration of anti-CCP antibodies or their seroconversion is observed for not all groups of anti-inflammatory drugs. Seropositivity for anti-CCP antibodies is a predictor of the higher efficacy of abatacept (ABC. The possibility of seroconversion of anti-CCP antibodies, like rheumatoid factor, during treatment with ABC is associated with the more pronounced suppression of clinical symptoms of RA activity and progressive joint destruction, with remission achievement in a large proportion of patients.

To test if the pannus tissue is characterized by a high receptor activator of nuclear factor kappaB ligand to osteoprotegerin (RANKL:OPG) ratio, which could explain local osteoclastogenesis and formation of bony erosions. Messenger RNA and protein expressions of RANKL and OPG in rheumatoid and osteoarthritic tissue samples were measured using quantitative real-time RT-PCR and Western blot/densitometry. Pannus and synovitis fibroblasts explanted from tissue samples were cultured in vitro without and with TNF-alpha, IL-1Beta or IL-17 and analyzed quantitatively for RANKL expression. The ability of pannus fibroblasts to induce formation of multinuclear osteoclast-like cells from human monocytes, with macrophage-colony stimulating factor (M-CSF) but without RANKL added, was tested. Histochemical staining was used to assess the eventual presence of RANKL and tartrate resistant acid phosphatase positive osteoclast-like cells at the pannus-bone interface. RANKL:OPG ratios of messenger RNA (ppannus (2.06+/-0.73 and 2.2+/-0.65) compared to rheumatoid (0.62+/-0.13 and 1.31+/-0.69) and osteoarthritis (0.62+/-0.32 and 0.52+/-0.16) synovial membranes. Resting and stimulated (p dependent on the cytokine used) pannus fibroblasts produced RANKL in excess (p=0.0005) and unstimulated pannus fibroblasts also effectively induced osteoclast-like cell formation from monocytes in vitro without any exogenous RANKL added. Compatible with these findings, multinuclear osteoclasts-like cells were frequent in the fibroblast- and macrophage-rich pannus tissue at the soft tissue-to-bone interface. The high RANKL:OPG ratio, together with close fibroblast-to-monocyte contacts in pannus tissue, probably favor local generation of bone resorbing osteoclasts at the site of erosion in rheumatoid arthritis.

Leprosy patients may present several osteoarticular complaints, which require further evaluation of inflammatory diseases, such as rheumatoid arthritis (RA). Therefore, an adequate clinical assessment in addition to testing for rheumatoid factors (RF) and anticyclic citrullinated peptide antibodies (anti-CCP), can be useful in order to establish the correct diagnosis. In this study, the relation of RF and anti-CCP with rheumatological manifestations was evaluated in 97 leprosy patients from Southern Brazil. The results were compared to RA patients and healthy controls from the same geographical area and ethnic background. Neuropathy was observed in 71.1% and arthritis in 35.1% of the leprosy patients. A high frequency of RF positivity was observed among the leprosy patients (41.2%, 40/97), with RF immunoglobulin A (IgA) significantly associated with arthritis (OR = 7.9, 95% CI = 1.5-40.6 P = 0.008). Anti-CCP was observed in 9.3% (9/97) of the patients, with anti-CCP2 being the most frequent subtype. Only 4.1% (4/97) of the patients were RF and anti-CCP concomitantly positive.

To determine whether weighting improves the correlation of ultrasound (US) score with serum matrix metalloproteinase-3 (MMP-3) level in rheumatoid arthritis (RA). As ultrasound examination was performed on 100 RA patients, and the severity of synovial effusion and synovial hypertrophy and the blood flow were semi-quantitatively graded from 0 to 3 by using the gray-scale (GS) and power Doppler (PD) modes. We then calculated the sums of the scores of the 28 joints of each patient in the 2 modes, that is, the GS28 and PD28 scores, as well as the respective scores weighted using the Lansbury articular index (LAI, shoulder and elbow, × 12; wrist, × 8; and knee, × 24)-Lans GS28 and Lans PD28 scores. The Lans PD28 score showed a higher correlation with MMP-3 (r = 0.591; 95% confidence interval, 0.446-0.705, p correlated well with the serum MMP-3 level. Weighting with the LAI can improve the correlation of US findings with serum MMP-3 level. Bidirectional approach based on both serum MMP-3 level and US scores can further improve the assessment of disease activity in RA patients.

Full Text Available Interleukin-6 (IL-6 is a pro-inflammatory cytokine that has been found to be increased in type 2 diabetic subjects. However, it still remains unclear if these elevated IL-6 levels are co-incidental or if this cytokine is causally related to the development of insulin resistance and type 2 diabetes in humans. Therefore, in the present study we examined insulin sensitivity, serum adipokine levels and lipid parameters in human subjects before and after treatment with the IL-6 receptor antibody Tocilizumab.11 non-diabetic patients with rheumatoid disease were included in the study. HOMA-IR was calculated and serum levels for leptin, adiponectin, triglycerides, LDL-cholesterol, HDL-cholesterol and lipoprotein (a (Lp (a were measured before as well as one and three months after Tocilizumab treatment. The HOMA index for insulin resistance decreased significantly. While leptin concentrations were not altered by inhibition of IL-6 signalling, adiponectin concentrations significantly increased. Thus the leptin to adiponectin ratio, a novel marker for insulin resistance, exhibited a significant decrease. Serum triglycerides, LDL-cholesterol and HDL-cholesterol tended to be increased whereas Lp (a levels significantly decreased.Inhibition of IL-6 signalling improves insulin sensitivity in humans with immunological disease suggesting that elevated IL-6 levels in type 2 diabetic subjects might be causally involved in the pathogenesis of insulin resistance. Furthermore, our data indicate that inhibition of IL-6 signalling decreases Lp (a serum levels, which might reduce the cardiovascular risk of human subjects.

We describe a 60-year-old woman with active rheumatoid arthritis (RA) and endstage renal disease secondary to hypertensive nephrosclerosis undergoing hemodialysis. She had tried multiple antirheumatic medications; however, their usefulness was limited due to toxic side effects or lack of efficacy. She was then treated with chimeric antitumor necrosis factor monoclonal antibody (infliximab), which resulted in immediate improvement in clinical and laboratory measures. After about 2 years of therapy, no side effects have been observed. This report expands the spectrum of infliximab to include RA patients with renal insufficiency.

Work was carried out on the serum of 100 healthy subjects and hundred Rheumatoid Arthritus patients by electrophoresis and atomic absorption model Hitachi-180-80. The different proteins fractions separated by electrophoresis were subjected for estimation of Cu-Concentration. It was found that only 5% copper is present in albumin which remains constant in normal and Rheumatoid Arthritus patients. The other important group of proteins were a2-globulins, in which Cu concentration was found high in Rheumatoid Arthritus patients as compared to normal subject. There was no copper detected in beta and gamma globulins. The study can be used for diagnostic purposes. Copper complexes of alpha 2-Globulins were found anti inflammatory in nature and this quality of self defense can bring revolution in the history of all infectious diseases including Rheumatoid Arthritus simply by separating the copper complexes of alpha 2-globulins (most probably ceruloplasmin) from the blood of donors and injecting into the body of patients. It is possible by this method that the disease-Rheumatoid Arthritus may be eradicated completely. These complexes have also shown antibiotic activity in gynae patients. (author)

To assess in one time window cardiovascular risks for both patients with gout and patients with rheumatoid arthritis in a Dutch primary care population. Retrospective matched cohort study with data from the electronic health records of 51 Dutch general practices. Participants were patients aged 30 years or older with an incident diagnosis of gout (n=2655) or rheumatoid arthritis (n=513), and matched non-disease controls (n=7891 and n=1850 respectively). At disease incidence date, patients and controls were compared for prevalence of hypertension, diabetes mellitus, hypercholesterolemia, and prior cardiovascular diseases. Patients without prior cardiovascular disease were followed for a first cardiovascular disease, and compared to controls using Kaplan-Meier survival curves and Cox proportional hazard analyses. Compared to controls, gout patients suffered more from hypertension (44.8%), diabetes (20.1%), hypercholesterolemia (13.7%), and prior cardiovascular disease (30%) (P0.05). After adjustment, both gout and rheumatoid arthritis patients without prior cardiovascular disease were more likely to get a cardiovascular disease: hazard ratio (95% confidence interval) 1.44 (1.18 to 1.76), and 2.06 (1.34 to 3.16) respectively. This primary care study indicates that gout and rheumatoid arthritis are both independent risk factors for cardiovascular diseases, rheumatoid arthritis to some greater extent, whereas gout patients at first diagnosis had already an increased cardiovascular risk profile. It gives strong arguments for implementation of both rheumatic diseases in primary care guidelines on cardiovascular risk management. Copyright © 2016 Société française de rhumatologie.

The radio-synoviorthesis with yttrium 90 in the knee-joint in rheumatoid arthritis was performed and controlled in 106 knees of patients with rheumatoid arthritis over a span of time between 6 and 49 months. The results are similar to those of other authors. As compared to synovectomy radio-synoviorthesis seems less successful as far as long-term results are concerned. As local treatment radio-synoviorthesis seems a good supplementory element in the therapeutic plan of rheumatoid arthritis. The indication to alternative procedures has been considered carefully for each individual case and joint. (orig.) [de

Full Text Available Rheumatoid arthritis (RA is an inflammatory multisystem disease of unknown etiology characterized by chronic destructive synovitis. It and #8217;s prevalence is about 1% all over the world. Serologic markers are also important beside some clinical situations upon RA diagnosis. Today, the most commonly used laboratory test is rheumatoid factor (RF in patients with suspected RA. RF is sensitive but not a specific biomarker for diagnosing RA. Early diagnosis of RA is essential to prevent of progressive joint damage. In recent years, anticyclic citrullinated peptide/protein antibody (anti-CCP attracts the attention as a remarkable biomarker for early diagnosis. Anti-CCP which is a family of anti-citrullinated protein antibodies (ACPA family, showed quite satisfactory specificity in the diagnosis of RA. Due to the prescence of ACPA was included to 2010 RA diagnostic criteria, in a manner of speaking, importance of anti-CCP was registered. [TAF Prev Med Bull 2014; 13(1.000: 83-88

An association between periodontal disease and rheumatoid arthritis is believed to exist. Most investigations into a possible relationship have been case-control studies with relatively low sample sizes. The advent of very large clinical repositories has created new opportunities for data-driven research. We conducted a retrospective cohort study to measure the association between periodontal disease and rheumatoid arthritis in a population of 25 million patients. We demonstrated that subjects with periodontal disease were roughly 1.4 times more likely to have rheumatoid arthritis. These results compare favorably with those of previous studies on smaller cohorts. Additional work is needed to identify the mechanisms behind this association and to determine if aggressive treatment of periodontal disease can alter the course of rheumatoid arthritis.

Carbohydrate metabolism disorders in patients with rheumatoid arthritis and ankylosing spondylitis – impact of the severity of the inflammatory process and disease activity

Full Text Available Carbohydrate metabolism disorders are much more common among rheumatoid arthritis (RA and ankylosing spondylitis (AS patients than in the general population. Chronic inflammation related to insulin resistance underlies the pathogenic mechanism of both rheumatoid disorders and diabetes. Interleukin-6 (IL-6 and tumour necrosis factor α (TNF-α as well as substances produced by adipose tissue, including free fatty acids, leptin, resistin, visfatin and adiponectin, play a crucial role in the development of insulin resistance. The data show that there is a strong relationship between high level of inflammatory markers and insulin resistance and higher risk of diabetes in patients with inflammatory rheumatic diseases. However, still other markers of disease activity are being sought, which could help to identify the patients with highest risk of impaired glucose tolerance. In the paper a literature overview has been presented concerning the assessment of risk of carbohydrate disorders among RA and AS patients and the disorders’ relationship with the intensity of non-specific inflammation and the disease activity.
