Abstract: Interest in B-cells has been revived due to the description of new functions. Supporting a role for B-cells in the genesis of autoimmune diseases is the fact that the B-cell activating factor of the TNF ligand family (BAFF) is essential in their physiology. However, in each disease, this is restricted to a subgroup of patients. Based on experiments in mice, and validated in humans, this new cytokine has been highlighted. Excessive production of BAFF alters immune tolerance by rescuing self-binding B-cells. Overexpression in mice leads to autoimmune manifestation, and BAFF levels are elevated in the serum of autoimmune patients. Similar abnormalities occur in chronic lymphocytic leukemia. Recent works suggest that antagonizing the protein (or competing for its receptors) is relevant to the treatment. Advances in our understanding of the BAFF system offers the opportunity to improve our therapeutic approach.

Abstract: T cells exert a fundamental role in different autoimmune chronic inflammatory diseases. The low-affinity autoreactive T cell clones provide the first amplification loop after the antigen (AgX) presentation, and if not counterregulated by the T regulatory cells (Treg), they maintain the inflammation and predispose to organ damage. Interrupting the T cell amplification loop through calcineurin antagonists leads to maintenance of the whole process under the autoimmune threshold.

Abstract: Combination therapy has emerged as a crucial therapeutic tool to control aggressive rheumatoid arthritis (RA). Cyclosporine (CsA) when combined with methotrexate (MTX) has shown substantial benefit in clinical practice. The primary benefit is its positive effect in the control of joint-bone erosions. The most feared adverse effect is the development of nephrotoxicity, which may be in part hemodynamic and in part structural, i.e. fibrotic. Careful monitoring of concomitant drugs, hypertension and through blood levels should allow the patient to maintain normal renal function. The successful employment of CsA in lupus nephritis clearly supports this statement.

Abstract: TNF-alpha is thought to play a pivotal role in the initiation and perpetuation of the chronic inflammatory process in rheumatoid arthritis. TNF-alpha blockers such as infliximab and etanercept are currently used in the treatment of active rheumatoid arthritis (RA) when traditional DMARDs have failed and are effective in a significant proportion of patients. However, about one third are non-responders to anti-TNF-alpha.The aim of this study was to verify whether rheumatoid patients, after failing infliximab, can benefit from etanercept.We analysed 18 patients with active RA with no response to at least 3 DMARDs and where infliximab therapy had failed. The patients had received infliximab associated with methotrexate: eleven of them did not show any significant response, while seven patients, after a good response, relapsed. Etanercept was then started. EULAR criteria of response were used with calculation of activity index DAS28 at baseline, after 2 weeks, 3 months and every third month until last follow-up. A moderate or good response was achieved with etanercept in 13 out of 18 patients. From our experience, etanercept can be considered as a good alternative choice when infliximab has failed.

Abstract: OBJECTIVE: To assess the possible clinical and biological rescue of rheumatoid arthritis (RA) in 16 patients who were still active despite intensive combination therapy after receiving infliximab following the Anti-Tumour necrosis factor Trial in Rheumatoid Arthritis with Concomitant Therapy (ATTRACT) schedule. METHODS: Sixteen patients who were still active despite combination therapy with optimal doses of methotrexate (MTX 15-17.5 mg/week) and cyclosporin A (CsA 2.5-3.5 mg/day) received infliximab. Ten received their combination plus infliximab (Combi), and six received infliximab plus MTX alone (Mono). The follow-up was carried out for 30 weeks in all patients and for 46 weeks in eight. Efficacy and safety were examined. RESULTS: At entry, the mean disease activity score (DAS) was 5.6 (all patients had a DAS >3.7). After therapy, eight of 10 patients in Combi and four out of six in Mono showed an improvement of >50% in the initial swollen joint count, yet only one patient reached 50% improvement in the initial DAS after 30 weeks, and one patient had a DAS <2.4 (low disease activity). Of the eight patients who reached 46 weeks of follow-up, three showed an improvement in DAS of 50% and two had a DAS <2.4. When considering the change over time, the difference between DAS at entry and at week 30 was statistically significant only in patients receiving MTX plus CsA, while it was not significant in those receiving MTX only. Two patients developed recurrent febrile upper respiratory infections in the Combi therapy group, while two had a single febrile infection in the MTX alone group. Two patients became strongly anti-cardiolipin positive (IgM >40 MPL) and one developed a coronary syndrome. CONCLUSION: Infliximab can be added incrementally to MTX plus CsA, with favourable results in terms of efficacy and safety over time in severe rapidly aggressive and progressive RA. Finally, minor evidence emerged for a stronger efficacy of the Combi treatment compared with Mono.

Abstract: OBJECTIVE: To evaluate two monotherapies followed by step-up combination therapy with two or three complementary drugs in active rheumatoid arthritis (RA) in comparison with sulphasalazine (SSZ) alone. METHODS: One hundred and twenty-six consecutive patients with early active RA were enrolled in this open controlled clinical trial. The primary end-point was 50% improvement according to the ACR criteria (ACR50) at 6, 12 or 18 months. The secondary end-points were a full response (Magnusson criteria) and/or remission (ACR criteria) at 3 yr. Methotrexate (MTX) (group 1), cyclosporin A (CsA) (group 2) or SSZ (group 3) was used first. After 6 months, a combination of two drugs (CsA and MTX) was employed in groups 1 and 2. SSZ was added after 12 months if improvement was less than ACR50 with the combination. Group 3 continued with SSZ alone. RESULTS: After 6 months, 57% of patients in group 1, 31% of group 2 (MTX vs CsA, P=0.002) and 33% of group 3 (MTX vs SSZ, P=0.01) had reached ACR50 improvement according to intention-to-treat analysis. At month 12 after starting a drug combination, 67% of group 1 and 76% of group 2 had reached ACR50 compared with 24% of group 3. At the 18-month follow-up, 90% of group 1 and 88% of group 2 but only 24% of group 3 had reached ACR50. After 18 months, 62% of group 1, 60% of group 2 and 48% of group 3 showed side-effects and three, five and eight patients in the three groups respectively had dropped out of the study. At the 3-yr follow-up, 9% of the patients in groups 1 and 2 and 7% of group 3 were in remission according to the ACR criteria; according to the Magnusson criteria, 40% showed a full response in groups 1 and 2 but only 21% did so in group 3. CONCLUSION: MTX appears to be the fastest-acting agent. A step-up approach with MTX plus CsA plus SSZ led to a 50% improvement according to the ACR criteria in most patients. After 3 yr, 40% of patients receiving combination therapy and 21% of patients receiving monotherapy showed a full response, while 9 and 7% respectively attained remission.

Abstract: INTRODUCTION: Type II collagen is a DR4/DR1 restricted target of self-reactive T cells that sustain rheumatoid arthritis. The aim of the present study was to analyze the T-cell receptor repertoire at the onset of and at different phases in rheumatoid arthritis. METHODS: We used the CDR3 BV-BJ spectratyping to study the response to human collagen peptide 261-273 in 12 patients with DR4+ rheumatoid arthritis (six at the onset of disease and six during the course of disease) and in five healthy DR4+ relatives. RESULTS: The collagen-specific T-cell repertoire is quite restricted at the onset of disease, involving approximately 10 rearrangements. Within the studied collagen-specific rearrangements, nearly 75% is shared among patients. Although the size of the repertoire used by control individuals is comparable to that of patients, it is characterized by different T-cell receptors. Part of the antigen-specific T-cell repertoire is spontaneously enriched in synovial fluid. The specific T-cell repertoire in the periphery was modulated by therapy and decreased with the remission of the disease. Failure of immunoscopy to detect this repertoire was not due to suppression of collagen-driven proliferation in vitro by CD4+ CD25+ T cells. Clinical relapse of the disease was associated with the appearance of the original collagen-specific T cells. CONCLUSIONS: The collagen-specific T-cell receptor repertoire in peripheral blood and synovial fluid is restricted to a limited number of rearrangements in rheumatoid arthritis. The majority of the repertoire is shared between patients with early rheumatoid arthritis and it is modulated by therapy.

Abstract: OBJECTIVE: To investigate the role of the HS1,2 enhancer polymorphisms as a new candidate marker for rheumatoid arthritis (RA) and to define the possible association with autoantibody positivity and clinical outcome. METHODS: Genomic DNA was obtained from two cohorts of patients with RA (100 with early RA (ERA) and 114 with longstanding RA (LSRA)) and from 248 gender-matched controls from the same geographical area. Clinical and immunological characteristics were recorded for all the patients. RESULTS: The percentage of the 2/2 genotype was higher in patients with ERA (27.0%), and in patients with LSRA (34.2%), than in controls (14.9%) (ERA: OR = 2.11 (95% CI 1.20 to 3.70) vs controls; LSRA: OR = 2.96 (95% CI 1.76 to 5.00) vs controls). A lower representation of allele *3 was present in patients with ERA (2.0%) than in controls (6.0%; OR = 0.32 (95% CI 0.11 to 0.91)). No significant associations were found between polymorphisms and autoantibodies positivity. CONCLUSION: The HS1,2A allele *2 associates with early and longstanding RA.

Abstract: OBJECTIVE: To determine factors affecting the severity of cognitive impairment in systemic lupus erythematosus (SLE) and to analyze its anatomic location. METHODS: Fifteen cognitive functions grouped into 8 domains were evaluated in 52 patients with SLE and 20 with rheumatoid arthritis. Patients were classified according to severity of impairment as normal, mild, or moderate/severe. Multivariate analysis was performed to identify the main factors affecting severity of cognitive deficits. The most likely anatomic site of damage according to neuropsychological performance was compared with the lesion's location on magnetic resonance imaging (MRI). RESULTS: In SLE patients, a stepwise regression analysis showed that the number of impaired functions (dependent variable) was associated with antiphospholipid antibody positivity (aPL+; P = 0.04), the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI; P = 0.001), hypertension (P = 0.032), and was inversely related to educational level (P = 0.021). Including MRI, the number of impaired functions was associated with severity of MRI (P < 0.001), the SDI (P = 0.013), and the presence of Raynaud's phenomenon (P = 0.04). The contemporary presence of aPL+ and Raynaud's phenomenon resulted in a higher probability to develop moderate/severe cognitive deficits (P = 0.015). Two logistic multiple regression analyses identified hypertension (P < 0.05), the SDI (P < 0.01), and moderate/severe MRI findings as main predictors of moderate/severe impairment (dependent variable). The damage site hypothesized through neuropsychological testing corresponded with MRI findings in 71.7% of SLE patients K = 0.42, P = 0.005). CONCLUSION: Hypertension, aPL+, accumulated damage, and MRI lesions are the main factors affecting severity of cognitive impairment in SLE. The hypothesized sites of central nervous system involvement according to neuropsychological testing correlated with MRI findings in most patients.

Abstract: OBJECTIVE: To assess the prevalence of good clinical response and remission in rheumatoid arthritis (RA) patients with longstanding disease treated with anti-tumor necrosis factor-alpha (TNF-alpha) drugs at outpatient clinics. METHODS: Retrospective national study of 14 academic tertiary referral rheumatology medical centers. RA patients with a Disease Activity Score (DAS28) > 3.2 were defined as having active disease and could start TNF-alpha blockers. All patients received one TNF-alpha blocker plus methotrexate (10-20 mg/wk). At the third month the patients were categorized as responders or nonresponders, based on improvement of at least 0.25 of the Health Assessment Questionnaire (HAQ). Those who had improved by at least 0.25 HAQ were analyzed for possible predictors of DAS28 remission at the sixth month. RESULTS: A total of 1257 patients started TNF-alpha blockers. Of these, 591 (46.7%) reached the sixth month with an improvement of HAQ of 0.25 at the third month. In the cohort of patients reaching HAQ of 0.25, DAS28 remission was seen in 24% of rheumatoid factor (RF)-positive and 36% of RF-negative patients (p = 0.03). Logistic regression analysis for predictors of remission identified age at baseline, HAQ < 1.63, and RF negativity as positive predictors of remission at 6 months along with sex (male). CONCLUSION: We show that only a minority of patients with longstanding RA achieve a good clinical response or remission at the outpatient community level. Predictors of remission identify characteristics commonly observed in subsets with less severe RA.

Abstract: OBJECTIVE: To investigate the effect of pilocarpine on the salivary peptide and protein profile in patients with primary Sjögren's syndrome (SS) and to study the differences between patients with primary SS, patients with SS associated with other rheumatic diseases, and healthy control subjects. METHODS: Saliva specimens were obtained from 9 primary SS patients, 9 secondary SS patients, and 10 healthy controls. Samples were analyzed for levels of 62 different salivary proteins using high-performance liquid chromatography coupled with mass spectrometry using a spectrometer equipped with an electrospray ionization source. In 6 of the primary SS patients, saliva was collected at 30 minutes, 60 minutes, and 24 hours after taking 5 mg of pilocarpine. RESULTS: Before pilocarpine, approximately 60% of salivary proteins in samples from primary SS patients were not identifiable or showed lower levels than those in healthy controls. After 30-60 minutes following pilocarpine treatment, approximately one-third of the less represented proteins was found in a similar percentage of primary SS patients and controls. Almost all of the proteins that were detectable at lower levels in primary SS patients compared with controls reached levels similar to those in controls at 30-60 minutes after pilocarpine. The parotid gland proteins had the best response to pilocarpine. Primary SS patients were characterized by higher alpha-defensin 1 levels and by the presence of beta-defensin 2. Secondary SS patients showed an intermediate protein profile between that of the primary SS patients and the controls. CONCLUSION: Pilocarpine partially restored the levels and numbers of identifiable proteins in saliva from patients with primary SS. Higher levels of alpha-defensin 1 and the presence of beta-defensin 2 in the saliva of patients with primary SS could be markers of oral inflammation in this patient group.

Abstract: OBJECTIVE: To assess the relationship between tumor necrosis factor receptor II (TNF-RII) gene polymorphisms and sTNFRII plasma levels in healthy blood donors (HBDs) and in rheumatoid arthritis (RA) patients. 113 HBDs and 49 RA patients were genotyped for the T/G polymorphism in exon 6 of the TNF-RII gene. In the same cases, sTNF-RII plasma levels were determined by an enzyme-linked immunosorbent assay (ELISA) procedure. sTNF-RII levels were higher in RA patients than in HBDs (p < 0.0001). No difference in sTNF-RII levels arose between RA patients on low oral doses of glucocorticoids versus those not taking glucocorticoids. In healthy controls, we observed lower levels of the sTNF-RII in carriers of the TT genotype compared to TG/GG genotype (p = 0.04). In RA there was the same behaviour between TT and TG/GG carriers, even though the difference was not statistically significant. When analyzing the correlation between sTNF-RII plasma levels and disease activity parameters, significant correlations were seen with disease activity score (r = 0.40, p = 0.01), swollen joint count (r = 0.38, p = 0.01), and tender joint count (r = 0.42, p = 0.01), but not with erythrocyte sedimentation rate (r = 0.22, p = ns) nor with C-reactive protein (r = 0.14, p = NS). The correlation remained significant only in the RA subgroup carrying the TT genotype. Healthy donors carrying the TT genotype showed lower sTNF-RII plasma levels than carriers of the TG/GG genotypes, while in RA patients we observed only a trend.

Abstract: OBJECTIVE: To compare the discriminating ability of the chronic arthritis systemic index (CASI), an index that uses the Health Assessment Questionnaire (HAQ) as the main variable, with the disease activity score (DAS) and Thompson's articular index (TAI) to detect high and low disease activity in rheumatoid arthritis (RA). METHODS: Two hundred and two RA patients were examined. According to criteria proposed previously, they were divided into two subgroups: those with active disease and those with low activity. The areas under receiver operating characteristic (ROC) curves were employed to assess the diagnostic accuracy of the CASI in comparison with the DAS and TAI for the discrimination of disease activity. RESULTS: The difference between areas under the ROC curves of the CASI and TAI (0. 897+/-0.023 vs 0.780+/-0.032) and between the DAS and TAI (0.933+/-0. 018 vs 0.780+/-0.032) was highly significant (P=0.0001), thus reflecting the accuracy of the diagnostic assessment. No difference arose between areas under the ROC curves of the CASI and the DAS (difference between areas=0.036+/-0.022; P=0.103). CONCLUSION: The CASI discriminates just as well between high and low disease activity as does the DAS. Either index consisting of more than one variable performs better than TAI. We conclude that even including the HAQ, a severity parameter in the long term, it is possible to construct an index that, at any time point, evaluates disease activity as well.

Abstract: OBJECTIVE: Murine models (MRL/gld/gld mice) and recent evidence in humans suggest a possible role of Fas and Fas ligand (Fas-L) germline mutations in the pathogenesis of autoimmune-related lymphoproliferation, including adult cases. In this study, the presence of Fas and Fas-L germline mutations was investigated in a consecutive series of adult patients with lymphoproliferative disorders occurring in the context of Sjögren's syndrome (SS) and type II mixed cryoglobulinemia (MC). METHODS: 11 patients (8 primary SS and 3 type II MC; F/M: 10/1; mean age 64 yrs.) were investigated. All patients were suffering from atypical lymphoproliferative disorders or MALT lymphoproliferative lesions (mean duration 3.5 yrs.). Four patients later developed a malignant lymphoma. DNA from peripheral blood mononuclear cells from 11 patients and 10 controls was tested for germline mutations in the Fas gene (exons 4, 8 and 9) and Fas-L gene (exon 4) by the polymerase chain reaction-single strand conformation polymorphism (SSCP) method. RESULTS: All DNA samples from both patients and controls showed amplification of Fas and Fas-L specific fragments. Identical SSCP migration patterns were observed in all the cases, indicating the lack of mutations in the whole series. CONCLUSION: Although it cannot be excluded that Fas and Fas-L mutations might be present in exons different from those analyzed, our data do not support the hypothesis that germline mutations in these genes are responsible for a major subset of lymphoproliferative syndromes in adult patients with SS and type II MC. Additional studies would be worthwhile in SLE-related lymphoproliferation, which is, however, a subset of limited clinical relevance when considering all cases with autoimmune-related lymphoproliferation.
