Abstract: OBJECTIVE: To formulate EULAR recommendations for the management of early arthritis. METHODS: In accordance with EULAR's "standardised operating procedures", the task force pursued an evidence based approach and an approach based on expert opinion. A steering group comprised of 14 rheumatologists representing 10 European countries. The group defined the focus of the process, the target population, and formulated an operational definition of "management". Each participant was invited to propose issues of interest regarding the management of early arthritis or early rheumatoid arthritis. Fifteen issues for further research were selected by use of a modified Delphi technique. A systematic literature search was carried out. Evidence was categorised according to usual guidelines. A set of draft recommendations was proposed on the basis of the research questions and the results of the literature search.. The strength of the recommendations was based on the category of evidence and expert opinion. RESULTS: 15 research questions, covering the entire spectrum of "management of early arthritis", were formulated for further research; and 284 studies were identified and evaluated. Twelve recommendations for the management of early arthritis were selected and presented with short sentences. The selected statements included recognition of arthritis, referral, diagnosis, prognosis, classification, and treatment of early arthritis (information, education, non-pharmacological interventions, pharmacological treatments, and monitoring of the disease process). On the basis of expert opinion, 11 items were identified as being important for future research. CONCLUSIONS: 12 key recommendations for the management of early arthritis or early rheumatoid arthritis were developed, based on evidence in the literature and expert consensus.

Abstract: Rheumatoid arthritis is a chronic inflammatory disease characterized by synovial inflammation and pannus formation leading to destruction of cartilage and bone. Several self proteins have been suggested to be disease-driving autoantigens. Proteins are encoded by a limited number of genes in our genome. Post-translational modifications such as citrullination of the arginine residues, can increase the morphological and the functional diversity of the proteome. The positivity of anti-citrullinated peptides autoantibodies occurs then at an early stage of the disease development. Several factors, among which the synovial tissue inflammatory and the nitric oxide reaction, are involved in the regulation of the citrullination reaction. All of them have to be analysed and considered to understand the loss of tolerance and the development of autoimmunity leading to the disease.

Abstract: B cells as autoantibody producing cells are major players in several autoimmune chronic inflammatory diseases (ACIDs). In some particular settings (i.e. Sjogren's syndrome, rheumatoid arthritis), the activated B cells could undergo malignant clonal expansion. Chronic infections by lymphotropic viruses (hepatitis C virus, Epstein Barr Virus, Herpes 6 and 8 viruses) could amplify the activation process by inducing antiapoptotic signals that lead to a longer survival of B cell subsets. This might then lead, through multiple oncogenic events, to benign first and malignant thereafter clonal B cell expansion. Understanding how the B cell are activated, how the B cell receptor activation can be maintained under control, which check-points could be deregulated and lead to a persistent activation is of crucial importance in benign and malignant diseases. The evidence suggests that the B cells faulty check-points are different in chronic lymphocytic leukaemia, in cryoglobulinemia, rheumatoid arthritis, systemic lupus erythematosus and systemic sclerosis.

Abstract: Cardiovascular disease (CVD) is responsible for 35-50% of rheumatoid arthritis (RA) deaths, whereas, in the general UK adult population, coronary heart disease is responsible for 1/4 deaths in males and 1/5 deaths in female. This increased risk may be attributable to RA-specific risk factors such as hyperhomocysteinemia, disease-related dyslipidemia or vascular inflammation, or to morbidity related to medications and high levels of tumor necrosis factor-alpha (TNF-alpha). The possible roles of TNF-alpha in the development of atherosclerosis include the recruitment of inflammatory cells to the site of injury or the promotion of adverse vascular smooth muscle cell remodelling. TNF-alpha may also act as a proinflammatory factor in plaque rupture. Anticytokine therapy could prove beneficial in the treatment of patients with heart failure. While early studies supported this hypothesis, anti-TNF strategies have not demonstrated salutary benefits in large multicenter randomized and placebo-controlled clinical trials in patients with symptomatic heart failure. There is a variety of possible explanations for the failure of anti-TNF therapy: (1) TNF antagonism has untoward effects in the setting of heart failure; (2) the biological agents used in the trials were intrinsically toxic; (3) sex and race may have important implications in the outcome after anticytokine therapy; (4) the TNF-alpha protein contains a polymorphism, and, in fact, genoma plays a role in modifying the pharmacologic response to anticytokines; (5) anti-TNF-alpha approaches could have had pharmacodynamic interactions with other heart failure medications; and (6) the patients in these trials may have been inappropriately selected. These disappointing results may determine controversial attitude in the long-term treatment with anti-TNF agents in RA or Crohn's disease. The effects of TNF-alpha blockers on incident cases of congestive heart failure (CHF) in RA are controversial. The available published data suggest the following: (a) RA patients with history of CHF and a concomitant indication for the use of TNF-alpha blockers do not need a baseline cardiac evaluation to screen for heart failure; (b) patients with well-compensated mild CHF New York Heart Association (NYHA) classes I and II and a concomitant indication for the use of TNF-alpha blockers should be evaluated at baseline and then be closely monitored for any clinical signs of worsening heart failure; and (c) patients with (NYHA) class III or IV heart failure should not be treated with TNF-alpha blockers in any case.

Abstract: Recently, a new member of the TNF family, BLyS, was identified. This protein, synthesized by myeloid cell lines, specifically interacts with B lymphocytes and increases their life-span. BLyS was studied in the murine models of some autoimmune diseases and it was demonstrated that it has a key role in the B lymphocyte system homeostasis and in the relation between chronic inflammation and autoimmunity. Analysis of BLyS plasma levels in Systemic Lupus Erythematosus, Sjogren's Syndrome and Rheumatoid Arthritis (RA) has shown that BLyS is higher in a group of patients than in the controls. In RA, BLyS correlates with the disease activity, in particular, with the swollen joints count; so, at least part of the chronic rheumatoid synovitis could be the epiphenomenon of the B cells activation driven by monocyte-macrophage population. More studies are necessary to understand the role of BLyS in the interaction between the monocyte and the B lymphocyte in some autoimmune disease and the possible usefulness of this cytokine as a diagnostic or prognostic marker and/or therapeutic target.

Abstract: Rheumatoid arthritis is a disease at high cardiovascular risk. It has recently been shown that RA patients with more than 10 years disease duration present a risk of myocardial infarction more than three times higher than osteoarthritis controls. The major determinant is thought to be the chronic inflammatory process, driven by some key cytokines among which TNF alpha is thought to play the leading role in the majority of the patients. TNFalpha, therefore, once blocked by specific inhibitors like TNF alpha blockers (Infliximab, Etanercept) should profoundly decrease the cardiovascular risk. However, TNF blockers induce the appearance of autoimmunity though in a small minority of the patients. This autoimmunity is thought to be due to the poor clearance of apoptotic bodies once the systemic inflammation (CRP, SAP) is controlled by the specific blockers, and to the lack of control of some B cell populations producing autoantibodies to specific autoantigens. Among the autoantibodies arising during TNF blockade, anticardiolipin appear to be the most crucial with respect to the cardiovascular risk. The appearance of anticardiolipins at clinically significant levels appears to be driven by two possible mechanisms, one due to common infections of the urinary or upper airways tract during blockade of soluble TNF alpha, the other due to the escape of some autoreactive B cells during blockade of soluble and membranous TNF alpha. Since both autoantibodies related to infections as well as the high levels unrelated to infections, can be well controlled by appropriate therapies, clinicians should pay attention to the biological phenomenon before it becomes a clinical problem.

Abstract: Several recent clinical studies have clearly established that rheumatoid arthritis (RA) is a disease identifiable since its early phases, a disease that can be adequately and efficaciously treated provided the therapeutic program can be started early on. To reach the aim of controlling effectively the disease and of leading the patients to live a normal life, several points must be fulfilled. The first is an early diagnosis obtained through a careful clinical examination along with an appropriate laboratory immunological work-up, followed by an adequate monotherapy within the first 4 months from symptoms onset. The second is the therapeutic re-assessment that needs to be done every three months, to start a possible combination therapy (COMBO), in order to rescue monotherapy failures. The third is the initiation of biological response modifiers (BRMs) within 6 months from monotherapy onset, within 3 months from COMBO in the most resistant cases. Having at hand several molecules with BRMs characteristics, we believe that the future appears much more favourable in most cases even in those with the severe disease.

Abstract: Earlier reports, including a comprehensive 1983 review, had indicated that slowing of radiographic progression was relatively unusual in treatment of rheumatoid arthritis (RA) using traditional disease modifying anti-rheumatic drugs. However, in recent years, slowing of radiographic progression has been documented in a number of clinical trials, as well as long-term observational studies, with use of (in alphabetical order) adalimumab, anakinra, corticosteroids, cyclophosphamide, cyclosporin, etanercept, gold salts, infliximab, leflunomide, methotrexate and sulphasalazine. At this time, disease modification is a realistic goal in the clinical care of patients with RA. Documentation of improved long-term outcomes requires long-term observational data over 5-20 yr to supplement data from randomized controlled clinical trials over 6-24 months.

Abstract: A classification of nonmalignant lymphoproliferation in Sjögren's syndrome is presented, based on the results of international meetings regarding Sjögren's syndrome-associated lymphomagenesis and on our results of a clinico-pathologic and molecular study and long-term follow-up in well-characterized patients. Sjögren's syndrome pathobiology has similarities to hepatitis C virus-related B-cell lymphoproliferation. Antigen stimulation with the preferential expansion of rheumatoid factor-positive clones and specific immunoglobulin gene expression and recombination represent key biologic events in lymphoproliferation. This classification is based on the coupling of molecular and histological studies and may result in more selective treatment approaches.

Abstract: OBJECTIVE: To determine the safety and efficacy of additional courses of rituximab in patients with rheumatoid arthritis (RA). METHODS: An open-label extension analysis of RA patients previously treated with rituximab was conducted. Patients who had participated in any of 3 double-blind trials were eligible for additional courses (2 infusions of 1,000 mg given 2 weeks apart) if they exhibited a swollen joint count and tender joint count of > or =8 with > or =16 weeks elapsing after the previous course. Safety was assessed in patients receiving all or a portion of a rituximab course. Efficacy was assessed 24 weeks after each course, using the American College of Rheumatology 20% criteria for improvement (ACR20), ACR50, ACR70, European League Against Rheumatism (EULAR) response criteria, Disease Activity Score in 28 joints, the disability index of the Health Assessment Questionnaire, and Short Form 36 scores, stratified according to prior tumor necrosis factor (TNF) inhibitor exposure. RESULTS: A total of 1,039 patients received > or =1 course of rituximab. Of these, 570 received 2 courses, 191 received 3 courses, and 40 received 4 courses, for a total of 1,669 patient-years. Irrespective of prior TNF inhibitor exposure, ACR20 responses were comparable at week 24 after course 1 and at week 24 after course 2 (65% versus 72%), as were ACR50 and ACR70 responses. EULAR moderate/good responses were also comparable in course 2 relative to course 1 (88% versus 79%), with EULAR remission occurring in a 2-fold higher proportion of patients after course 2 than after course 1 (13% versus 6%). The most common adverse events, which were mild-to-moderate acute infusion-related events, decreased with each course. The serious infection rate after course 1 (5.1 per 100 patient-years) remained stable through additional courses. The proportion of patients with circulating IgM and IgG levels below the lower limit of normal (LLN) increased with subsequent courses; however, serious infection rates in these patients (5.6 per 100 patient-years in patients with low IgM levels and 4.8 per 100 patient-years in patients with low IgG levels were comparable with those in patients with immunoglobulin levels above the LLN (4.7 per 100 patient-years). Patients with human antichimeric antibody (9.2%) did not exhibit decreasing efficacy or present additional safety concerns. CONCLUSION: These findings indicate that patients treated with repeated courses of rituximab have sustained clinical responses with no new adverse events.

Abstract: BACKGROUND: Patients with rheumatoid arthritis (RA) have endothelial dysfunction, which may predispose them to the risk of premature atherosclerosis. This study investigated the involvement of tumor necrosis factor (TNF) alpha in the pathophysiologic characteristics of this abnormality by use of the TNF-alpha-neutralizing antibody infliximab. METHODS: Endothelium-dependent and -independent vasodilator responses to intra-arterial infusion of increasing doses of acetylcholine and sodium nitroprusside, respectively, were assessed by strain-gauge plethysmography in patients (n = 10) with early RA during saline solution infusion and after intra-arterial infusion of infliximab (200 microg/min). RESULTS: Circulating markers of systemic inflammation (C-reactive protein and interleukin 6) were higher in patients than in control subjects (n = 10, both P < .05), whereas plasma levels of TNF-alpha and soluble TNF receptor types 1 and 2 were similar in both groups (all P > .05). During saline solution infusion, the vasodilator response to acetylcholine was blunted in patients with RA compared with control subjects (14.2 +/- 9.2 mL . min-(1). dL-(1) versus 23.7 +/- 9.2 mL . min-(1). dL-(1) at the highest dose, P = .004) whereas vasodilation to sodium nitroprusside was not different between groups (P = .10). In patients with RA infliximab did not modify circulating C-reactive protein levels (P = .29, versus saline solution) but did potentiate the vasodilator response to acetylcholine (21.0 +/- 11.1 mL . min-(1). dL-(1); P = .004, versus saline solution). The response to sodium nitroprusside, in contrast, was not modified by infliximab (P = .28 versus saline solution). CONCLUSIONS: Intravascular administration of anti-TNF-alpha antibody ameliorates endothelial function in patients with RA but does not concurrently affect systemic inflammatory changes. Our findings suggest that enhanced TNF-alpha generation within the vessel wall, rather than systemic mechanisms, plays a role in the pathobiologic features of endothelial dysfunction in RA.

Abstract: OBJECTIVE: Given the role of TNF-alpha in Rheumatoid Arthritis (RA) we decided to define the characteristics of the TNF-alpha synthesis by peripheral blood mononuclear cells (PBMNCs) obtained from active-aggressive RA patients giving a particular attention to the modulation of the expression of two fundamental proteins in TNF-alpha mRNA stability regulation, Tristetraprolin (TTP) and HuR. METHODS: 11 RA patients with active disease were enrolled in the study before their entry in 2 double blind protocols: Infliximab versus MTX and Etanercept versus MTX. 9 healthy blood donors were taken as controls. PBMNCs obtained by Ficoll centrifugation and plastic adherence were stimulated with lipopolysaccharide (LPS) and TNF-alpha was measured in the supernatant during 8 hours by ELISA. At each time point the cells were harvested and analysed for TNF-alpha, TTP and HuR mRNA expression by semi-quantitative PCR. RESULTS: MNCs TNF-alpha secretion after LPS stimulation did not differ significantly between RA and control subjects, even if a tendency towards a more prompt response was observed in the patients. More importantly only the DMARDs responsive patients (DAS < 3.7 at the 6th month, with a minimal reduction of 1.2 points) disclosed precociously (at the first month) a significant change in the profile of TNF-alpha secretion and maintained it until the 6th month. The "normalization" of the synthetic behaviour was accompanied by the resetting in the regulation of the expression of the TTP, that appeared significantly different in the patients before and after therapy. CONCLUSIONS: Independently from the type of therapy, responsive patients demonstrate a rapid change in the cellular biology at the systemic level that might drive the resolution of the inflammatory process at the synovial level.

Abstract: OBJECTIVE: The pathogenetic role of B cells in rheumatoid arthritis (RA) is under debate, but it is currently believed to be marginal. The availability of selective anti-B cell treatment provides a unique opportunity to clarify this issue. This study was undertaken to investigate the effects of B cell blockade in the treatment of refractory RA, and to evaluate the implications with regard to the role of B cells in the disease. METHODS: Five female patients with active, evolving erosive RA were treated with rituximab, an anti-CD20 chimeric monoclonal antibody. All 5 patients had been nonresponders to combination therapy with methotrexate plus cyclosporin A. Two of the 5 had also failed to respond to anti-tumor necrosis factor alpha therapy. All of these treatments were discontinued 1 month before institution of anti-CD20 therapy. RESULTS: Marked clinical improvement was observed in 2 patients (American College of Rheumatology 70% response [ACR70] and ACR50, respectively), starting at the end of the second month after institution of anti-CD20 therapy (month 2) and lasting until month 10 in 1 patient (articular relapse) and month 12 in the other (last followup). ACR20 response was observed in 2 additional patients, lasting until month 5 and month 7, respectively (articular relapse in both). Decrease or normalization of serum C-reactive protein and rheumatoid factor levels were observed in these patients. In contrast, patient 3 had no response to the treatment. RA synovitis and evolving erosive damage were decreased in patients exhibiting a major response, as demonstrated by imaging studies. CONCLUSION: Our finding of the clinical efficacy of selective B cell blockade indicates that B cells play a critical role in rheumatoid synovitis, at least in a subset of patients. Qualitative or quantitative differences in B cell commitment in RA pathobiology might have a function in the different responses observed.

Abstract: BACKGROUND: Disease-modifying antirheumatic drugs (DMARDs) play a crucial role in the treatment of persistent chronic synovitis, such as active rheumatoid arthritis (RA) and spondyloarthritis, by inducing or maintaining disease remission, reducing the frequency of flares or relapses, and allowing corticosteroids to be tapered while maintaining disease control. OBJECTIVE: The aim of this retrospective study was to evaluate the safety of, and adherence to treatment with, leflunomide in elderly RA and psoriatic arthritis patients compared with younger patients. METHODS: A total of 90 Italian patients (80 with active RA and 10 with psoriatic arthritis) were retrospectively examined at entry and after 24 months' follow-up. Patients were divided into two groups according to age: those aged <or=65 years (n = 50) and those aged >65 years (n = 40). Each patient was analysed for clinical, demographic and laboratory parameters in order to evaluate liver, renal and haematological toxicity. Disease Activity Score including a 28-joint count (DAS28) and physician global assessment of disease activity (MD global) were measured to define disease activity. RESULTS: During the 24-month follow-up period, 30 patients (33.3%) discontinued leflunomide: 17 patients (34.0%) in the group of patients aged <or=65 years and 13 patients (32.5%) in those aged >65 years. There were no differences in treatment withdrawal between the two groups. Overall, 10 patients (11.1%) in the entire study population discontinued leflunomide for lack of efficacy, while 21 (23.3%) discontinued the drug because of adverse effects (one patient withdrew because of both inefficacy and adverse effects). There were no significant differences in efficacy or adverse effects between patients aged <or=65 years and patients aged >65 years. There was also no significant difference in survival rates of leflunomide treatment when patients aged <or=65 years were compared with patients aged >65 years (p = 0.94). There were no significant differences in withdrawal rates in the overall population when leflunomide monotherapy was compared with leflunomide combination therapy. There were also no significant differences in the types of adverse effects associated with monotherapy or combination therapy when the two age groups were compared. CONCLUSIONS: Leflunomide is a useful and well tolerated DMARD for the treatment of RA and psoriatic arthritis in the elderly. The safety profile of, and adherence to, leflunomide is not different in older patients with chronic inflammatory joint diseases such as RA or psoriatic arthritis to that observed in younger patients.

Abstract: B cells have acquired an important role in the pathogenesis of rheumatoid arthritis (RA) since B cell depletion allowed to rescue patients poorly responders to TNFalpha blockers. This study focused on the involvement of ZAP-70 as a bio-marker of B cells immune activation in RA. ZAP-70 expression in synovial fluid (SF) B cells obtained from RA patients was increased compared to SF B cells of osteoarthritis (OA) patients. Moreover we found that ZAP-70 positive/CD38 positive and ZAP-70 positive/CD5 positive B cells were enriched in SF. The analysis of B cell apoptosis in vitro showed that the percentage of ZAP-70 negative B cells spontaneously undergoing apoptosis was significantly higher than ZAP-70 positive B cells. The ZAP-70 positive B cell ratio (SF/peripheral blood (PB)) showed a positive correlation with SF autoantibody levels and with local levels of BAFF and IL6. ZAP-70 positive B cells seem to define a subset characterized by increased survival and high relationship with local inflammation and autoimmunity.

Abstract: OBJECTIVE: To compare the performance of different definitions of remission in a large multinational cross-sectional cohort of patients with rheumatoid arthritis (RA). METHODS: The Questionnaires in Standard Monitoring of Patients with RA (QUEST-RA) database, which (as of January 2008) included 5,848 patients receiving usual care at 67 sites in 24 countries, was used for this study. Patients were clinically assessed by rheumatologists and completed a 4-page self-report questionnaire. The database was analyzed according to the following definitions of remission: American College of Rheumatology (ACR) definition, Disease Activity Score in 28 joints (DAS28), Clinical Disease Activity Index (CDAI), clinical remission assessed using 42 and 28 joints (Clin42 and Clin28), patient self-report Routine Assessment of Patient Index Data 3 (RAPID3), and physician report of no disease activity (MD remission). RESULTS: The overall remission rate was lowest using the ACR definition of remission (8.6%), followed by the Clin42 (10.6%), Clin28 (12.6%), CDAI (13.8%), MD remission (14.2%), and RAPID3 (14.3%); the rate of remission was highest when remission was defined using the DAS28 (19.6%). The difference between the highest and lowest remission rates was >/=15% in 10 countries, 5-14% in 7 countries, and <5% in 7 countries (the latter of which had generally low remission rates [<5.5%]). Regardless of the definition of remission, male sex, higher education, shorter disease duration, smaller number of comorbidities, and regular exercise were statistically significantly associated with remission. CONCLUSION: The use of different definitions of RA remission leads to different results with regard to remission rates, with considerable variation among countries and between sexes. Reported remission rates in clinical trials and clinical studies have to be interpreted in light of the definition of remission that has been used.

Abstract: OBJECTIVE: The prevalence of concurrent rheumatoid arthritis (RA) and hepatitis C virus (HCV) infection is probably underestimated because of the increasing spread of this virus worldwide, especially in developing countries. In these patients, anti-tumor necrosis factor-alpha (anti-TNF-alpha) therapy may aggravate hepatitis and increase viremia. We evaluated the safety of these treatments, which remain controversial. METHODS: Thirty-one HCV-positive patients (23 women, 8 men, mean age 59+/-13 yrs, mean disease duration 13+/-11.5 SD yrs) with active RA [Disease Activity Score 28 (DAS28)>3.2] unresponsive to conventional therapies were treated with TNF-alpha blockers (infliximab 11, etanercept 17, adalimumab 3) at standard dosages. Safety and efficacy were evaluated at the third month of treatment and at the patient's last observation. RESULTS: A significant clinical-serological improvement was recorded at the 3-month reevaluation. Mean values of patients assessment of general health on visual analog scale (range 0.100) decreased from 69+/-29 (SD) to 35+/-27 (p<0.0001), Ritchie index from 21.6+/-13.9 to 10.1+/-3.7 (p<0.0001), erythrocyte sedimentation rate from 36+/-25 to 28+/-22 mm/h (p=0.04), and DAS28 from 5.2+/-1.6 to 2.78+/-1.3 (p<0.0001); a DAS28<2.6 was recorded in 15/31 (48%) patients. At the last observation 19 patients (61%) continued TNF-alpha blockers, and the observed benefits persisted after 22+/-11 months of followup. Mean values of transaminases (ALT) and HCV viral load showed no significant variations; TNF-alpha blockers were discontinued in only one patient because of persistently elevated ALT not correlated to the variations of HCV viremia; this latter increased significantly (>or=2 log10) in 4 cases. CONCLUSION: Previous observations had suggested the safety of TNF-alpha blockers for treatment of RA in patients with concurrent HCV infection. Given the clinical-therapeutic implications, our results support the safety of TNF-alpha blockers in patients with HCV, provided there is close monitoring of clinical and virological data (mainly ALT and HCV viremia).

Abstract: OBJECTIVE: To determine whether levels of B cell activating factor (BAFF), a member of the tumor necrosis factor family, relate to autoantibody levels, disease activity, and response to treatment in patients with early rheumatoid arthritis (ERA). METHODS: BAFF was measured by ELISA in 48 early RA patients; 21 were examined serially. These data were compared with 49 controls with longstanding RA (LSRA), 48 disease controls (DC), and 50 healthy controls (HC). RESULTS: BAFF levels were higher in ERA, compared with DC and HC [median 4.3 ng/ml (5th-95th: 0.8-38.8) vs 0.9 ng/ml (5th-95th: 0.7-4.5) and 2.0 ng/ml (5th-95th: 0.7-5.68), respectively; p <10(-4 )both comparisons], but not with LSRA controls [median 8.7 ng/ml (5th-95th: 0.8-46.1); p = nonsignificant]. BAFF correlated with the titers of IgM rheumatoid factor and anti-cyclic citrullinated peptide autoantibody (r = 0.76 and r = 0.49; p < 0.00001, p = 0.0001 for the 2 correlations), and with the number of swollen joints (r = 0.37; p = 0.01). The followup study of 21 methotrexate-treated ERA patients revealed reduced levels of BAFF, with parallel improvement in clinical activity and decrease in autoantibody titers. CONCLUSION: Elevated BAFF in a subset of ERA patients is related to autoantibody levels and synovitis. BAFF level diminished with treatment, along with autoantibody titers, suggesting a rationale to treat ERA patients with BAFF-targeted agents.

Abstract: INTRODUCTION: We analyzed the prevalence of cardiovascular (CV) disease in patients with rheumatoid arthritis (RA) and its association with traditional CV risk factors, clinical features of RA, and the use of disease-modifying antirheumatic drugs (DMARDs) in a multinational cross-sectional cohort of nonselected consecutive outpatients with RA (The Questionnaires in Standard Monitoring of Patients with Rheumatoid Arthritis Program, or QUEST-RA) who were receiving regular clinical care. METHODS: The study involved a clinical assessment by a rheumatologist and a self-report questionnaire by patients. The clinical assessment included a review of clinical features of RA and exposure to DMARDs over the course of RA. Comorbidities were recorded; CV morbidity included myocardial infarction, angina, coronary disease, coronary bypass surgery, and stroke. Traditional risk factors recorded were hypertension, hyperlipidemia, diabetes mellitus, smoking, physical inactivity, and body mass index. Unadjusted and adjusted hazard ratios (HRs) (95% confidence interval [CI]) for CV morbidity were calculated using Cox proportional hazard regression models. RESULTS: Between January 2005 and October 2006, the QUEST-RA project included 4,363 patients from 48 sites in 15 countries; 78% were female, more than 90% were Caucasian, and the mean age was 57 years. The prevalence for lifetime CV events in the entire sample was 3.2% for myocardial infarction, 1.9% for stroke, and 9.3% for any CV event. The prevalence for CV risk factors was 32% for hypertension, 14% for hyperlipidemia, 8% for diabetes, 43% for ever-smoking, 73% for physical inactivity, and 18% for obesity. Traditional risk factors except obesity and physical inactivity were significantly associated with CV morbidity. There was an association between any CV event and age and male gender and between extra-articular disease and myocardial infarction. Prolonged exposure to methotrexate (HR 0.85; 95% CI 0.81 to 0.89), leflunomide (HR 0.59; 95% CI 0.43 to 0.79), sulfasalazine (HR 0.92; 95% CI 0.87 to 0.98), glucocorticoids (HR 0.95; 95% CI 0.92 to 0.98), and biologic agents (HR 0.42; 95% CI 0.21 to 0.81; P < 0.05) was associated with a reduction of the risk of CV morbidity; analyses were adjusted for traditional risk factors and countries. CONCLUSION: In conclusion, prolonged use of treatments such as methotrexate, sulfasalazine, leflunomide, glucocorticoids, and tumor necrosis factor-alpha blockers appears to be associated with a reduced risk of CV disease. In addition to traditional risk factors, extra-articular disease was associated with the occurrence of myocardial infarction in patients with RA.

Abstract: OBJECTIVE: To evaluate the effect of adalimumab treatment on clinical remission and/or minimal disease activity (MDA) in 6,610 patients with active rheumatoid arthritis (RA) who were enrolled in the Research in Active RA trial, a multinational, open-label, 12-week study with an optional extension period. METHODS: Clinical remission was defined as a Disease Activity Score in 28 joints (DAS28)<2.6, Simplified Disease Activity Index (SDAI) score<or=3.3, or Clinical Disease Activity Index (CDAI) score<or=2.8. MDA required absence of tender and swollen joints plus erythrocyte sedimentation rate (ESR)<or=10 mm/hour; DAS28 score<or=2.85; or achievement of 5 of 7 core criteria for pain, swollen/tender joints, physical function, physician/patient global assessment, and ESR. Time to and time in remission/MDA and response predictors were analyzed using Kaplan-Meier estimates and Cox proportional hazards regression analysis, respectively. RESULTS: A total of 38%, 24%, and 27% of patients achieved remission defined as DAS28<2.6, SDAI<or=3.3, and CDAI<or=2.8, respectively. MDA was observed in 45% of patients by DAS28<or=2.85, in 43% by the core set of criteria, and in 13% by absence of tender/swollen joints plus ESR<or=10 mm/hour. Median times in continuous remission and MDA were 3.4 and 4.4 months, respectively. Predictors for remission (DAS28<2.6) and MDA (DAS28<or=2.85) were male sex; younger age; concomitant disease-modifying antirheumatic drug use; lower baseline DAS28, CRP concentration, and Health Assessment Questionnaire disease index score; <or=1 comorbidity; and tumor necrosis factor antagonist naivety. CONCLUSION: During adalimumab treatment, 25% of patients experienced clinical remission and nearly half achieved MDA. To our knowledge, this analysis represents the largest prospective clinical trial data set to be assessed using Outcome Measures in Rheumatology Clinical Trials MDA criteria.

Abstract: Considerable evidence indicates that patients with rheumatoid arthritis (RA) are at greater risk of developing atherosclerosis and cardiovascular disease. Recent studies support the predictive ability of endothelial function measures for subsequent atherosclerotic events. We have investigated the effects of infliximab, a chimeric monoclonal anti-tumor necrosis factor (TNF) antibody, on endothelial vasodilation, measured by brachial ultrasonography and on the levels of inflammatory biomarkers and adhesion molecules in ten consecutive patients with severe long-standing RA, despite methotrexate therapy, during the loading phase of infliximab therapy. Flow-mediated dilation (FMD) in RA patients at baseline was significantly impaired compared with healthy controls (7.71 +/- 2.78% vs 14.91 +/- 6.41%; p = 0.008) and improved significantly after infliximab infusion (12.63 +/- 1.63% vs 7.71 +/- 2.78%; p = 0.005). At baseline, a statistically significant correlation between C-reactive protein levels and FMD was found (r = -0.69, p = 0.026). However, this improvement was transitory, as FMD values returned to baseline values before each infliximab infusion at weeks 2, 6 and 14. There were no significant differences in baseline brachial artery diameter between visits, although at each time, the diameter was increased. According to European League Against Rheumatism response criteria, all ten patients were good responders. No significant differences were observed in intercellular cell adhesion molecule-1, vascular cell adhesion molecule-1, vascular endothelial growth factor and E-selectin plasma levels before and after each infusions. This study demonstrates that endothelial dysfunction is a reversible phenomenon in RA. The addition of anti-TNFalpha treatment reduces inflammatory symptoms in patients with severe RA. The improvement of endothelial function during the loading phase of therapy is transitory, suggesting an enhanced and persistent TNF-alpha generation within the arterial wall.

Abstract: OBJECTIVE: In 1999, the Italian Society of Rheumatology started a project to determine the prevalence and clinical characteristics of aggressive rheumatoid arthritis (ARA). METHODS: For 1 year, all patients with RA for > 5 years and referred to participating centers were entered in a registry and classified as having ARA if they fulfilled the following criteria: 10 swollen joints for at least 6 weeks, positive rheumatoid factor (RF), and at least one bone erosion (if disease duration of 2 years); (a) RF-positive and having 10 swollen joints or at least one newly eroded joint, or (b) if RF-negative, having 10 swollen joints and at least one newly eroded joint (if disease duration > 2 to < 5 years). RESULTS: The 94 participating centers enrolled 1218 patients with RA, 1130 of whom had enough data to be classified as ARA (29.0%) or non-ARA (71.0%). The frequency of ARA was 15% in the 2-year group and 63% in the > 2 to < 5-year group, but 35% of the patients in the 2-year group had erosions. Bone erosions were associated with disease duration, a Health Assessment Questionnaire value > 1.5, female sex, and RF positivity. Conditions other than RA were recorded in about 50% of the patients, and only 30% 40% were taking disease modifying antirheumatic drugs. CONCLUSION: In an Italian RA population, the GIARA (Gruppo Italiano Artrite Reumatoide Aggressiva) criteria for ARA were met by 15% of the patients with disease duration of 2 years, but erosions were seen in 35%. Upon referral, most of the RA patients were inadequately treated and had other conditions.

Abstract: A large number of experts experienced in the treatment of rheumatoid arthritis were involved in formulating a consensus statement on the use of B cell-targeted treatment with rituximab in patients with rheumatoid arthritis. The statement was supported by data from randomised controlled clinical trials and the substantial literature on oncology. The statement underwent three rounds of discussions until its ultimate formulation. It should guide clinicians in the use of this newly approved biological agent in treating patients with rheumatoid arthritis.

Abstract: OBJECTIVES: To analyze the association of interleukin (IL-1) gene polymorphisms with susceptibility to, and severity of, rheumatoid arthritis (RA) patients, comparing them with the genotype distribution in healthy controls. Also, to assess the influence of IL1-B and IL1RN gene polymorphism on IL-1beta/IL-1Ra plasma levels and response to therapy. PATIENTS AND METHODS: We tested the allelic distribution of IL-1B (-511 and +3953) and IL-1RN (variable number of tandem repeats) gene polymorphism in 126 RA patients and 178 healthy blood donors (HBDs). The patients were categorized into two subgroups in relation to the response to methotrexate (MTX) therapy. Group A included 70 RA patients in stable partial remission after 6 months of MTX treatment (MTX-R). Group B included 56 RA patients with active disease despite MTX therapy. This group received antitumor necrosis factor (TNF) biological drugs and were defined MTX-nonresponders (MTX-NR). RESULTS: None of the two IL-1B (-511 and +3953) gene polymorphisms were significantly different in frequency between RA patients and healthy controls. We observed an increased frequency of the rare allele IL1RN*3 in RA patients with active disease, not responding to MTX therapy (MTX-NR) (4.5%) vs MTX-R (3.6%) and healthy controls (0.8%). Interestingly, RA patients whose genotypes included the IL1RN*long allele (haplotype long-C-T) showed the worse response to MTX. HBDs harboring the IL1RN*2/2 genotype showed significantly lower levels of plasma IL1-Ra, but comparable levels of IL-1beta with regard to subjects with the presence of the IL1RN* long allele. Furthermore, the presence of the TT IL-1B +3953 genotype was associated with lower plasma levels of IL1-Ra, both in HBDs and in RA patients. Carriers of the IL1RN*2 allele responded better to infliximab therapy. CONCLUSIONS: The results of this study provide evidence of an association between the IL1RN*long allele and RA, the strongest association being observed in RA patients with an aggressive disease resistant to MTX treatment.

Abstract: OBJECTIVE: To evaluate the efficacy of switching to etanercept treatment in patients with rheumatoid arthritis who already responded to infliximab, but presented side effects. METHODS: Charts of 553 patients with rheumatoid arthritis were retrospectively reviewed to select patients who responded to the treatment with infliximab and switched to etanercept because of occurrence of adverse effects. Clinical data were gathered during 24 weeks of etanercept treatment and for the same period of infliximab treatment before infliximab was stopped. Disease Activity Score computed on 44 joints (DAS-44), erythrocyte sedimentation rate (ESR) 1st hour, Visual Analogue Scale (VAS) of pain, Health Assessment Questionnaire (HAQ), and C reactive protein (CRP) were assessed every 8 weeks. RESULTS: 37 patients were analysed. Adverse events to infliximab were mostly infusion reactions. No statistically significant difference between infliximab, before withdrawal, and etanercept, after 24 weeks, was detected in terms of DAS-44 (2.7 and 1.9, respectively), HAQ (0.75 and 0.75, respectively), ESR (21 and 14, respectively) and CRP (0.5 and 0.3, respectively). VAS pain decreased significantly after switching to etanercept treatment (40 and 24, respectively; p<0.05). CONCLUSIONS: Our study shows that etanercept maintains the clinical benefit achieved by infliximab, and suggests that a second tumour necrosis factor (TNF) alpha inhibitor can be the favourable treatment for rheumatoid arthritis when the first TNFalpha blocker has been withdrawn because of adverse events.
