    ABSTRACT: Primary Sjögren's syndrome is a systemic autoimmune disease, characterized by a lymphocytic exocrinopathy. Oral and ocular dryness, asthenia and pain represent hallmarks of the disease. Systemic manifestations concern a third of patients, including lymphoma in 5% of the patients. The American European Consensus Group classification criteria have been used in current practice and clinical trials since 2002. New classification criteria were recently proposed by the American Congress of Rheumatology. A group of international experts are currently working to reach a new consensus between the American European Consensus Group classification criteria and the American Congress of Rheumatology proposal for disease classification. In addition, international consensus disease activity scores were recently established. Regarding treatment modalities, symptomatic treatments remain the cornerstone of therapy in pSS, but new biologic treatments are currently evaluated.

    ABSTRACT: A large body of evidence supports the role of microRNAs (miRNAs) in inflammatory diseases. Concerning rheumatoid arthritis (RA), several miRNAs exhibiting deregulated expression pattern were identified in various fluids (serum or synovial) or different cell types (macrophages, synoviocytes). The potential interest of these molecules as biomarkers is increasingly considered, but their precise mode of action still remains largely hypothetical because the identification of their physiological mRNA targets is challenging. To evaluate the overall importance of miRNAS in the pathogenesis of RA, we investigated the expression of genes involved in miRNA biogenesis in FLS isolated from healthy donors and RA patients. We also used a mouse mutant line carrying a hypomorphic mutation in the Dicer gene to monitor the impact of reduced miRNA maturation on experimental arthritis triggered by K/BxN serum transfer. Human FLS were isolated from synovial tissues from RA and OA patients and healthy controls after informed consent. Mice FLS were isolated from Dicer d/d and littermates controls. IL-6 release was measured in culture supernatants and following RNA extraction using TRIzol and reverse transcription, real-time quantitative RT-qPCR was performed. Handling of mice and procedures were in accordance with the French Law for the Protection of Laboratory Animals and reviewed by the Regional Ethical Committee for Animal Experimentation (CREMEAS) of the Strasbourg University (authorisation number A-67-345). Serum collected from 9-week old arthritic K/BxN mice was used to trigger arthritis in adult Dicer (d/d) and + / + mice by two successive i.p. injection (150 μL). The articular arthritis index was visually determined on a 0-4 scale (0 = no swelling or erythema, 4 = excessive edema with joint rigidity). Dicer is the only gene involved in the miRNA biogenesis pathway showing significantly reduced expression in FLS isolated from RA patients compared to controls or OA. Similarly, mutant mice (Dicer (d/d)) with reduced Dicer expression exhibit more severe arthritis symptoms upon K/BxN serum transfer. miRNAs are important players to keep pro inflammatory molecules under tight control. Mutations globally affecting mature miRNAs production represent a previously unidentified risk factor for RA.

    ABSTRACT: Primary Sjögren syndrome (pSS) is an autoimmune disorder characterized by ocular and oral dryness or systemic manifestations. To evaluate efficacy and harms of rituximab in adults with recent-onset or systemic pSS. Randomized, placebo-controlled, parallel-group trial conducted between March 2008 and January 2011. Study personnel (except pharmacists), investigators, and patients were blinded to treatment group. (ClinicalTrials.gov: NCT00740948) SETTING: 14 university hospitals in France. 120 patients with scores of 50 mm or greater on at least 2 of 4 visual analogue scales (VASs) (global disease, pain, fatigue, and dryness) and recent-onset (<10 years) biologically active or systemic pSS. Randomization (1:1 ratio) to rituximab (1 g at weeks 0 and 2) or placebo. Primary end point was improvement of at least 30 mm in 2 of 4 VASs by week 24. No significant difference between groups in the primary end point was found (difference, 1.0% [95% CI, -16.7% to 18.7%]). The proportion of patients with at least 30-mm decreases in at least two of the four VAS scores was higher in the rituximab group at week 6 (22.4% vs. 9.1%; P = 0.036). An improvement of at least 30 mm in VAS fatigue score was more common with rituximab at weeks 6 (P < 0.001) and 16 (P = 0.012), and improvement in fatigue from baseline to week 24 was greater with rituximab. Adverse events were similar between groups except for a higher rate of infusion reactions with rituximab. Low disease activity at baseline and a primary outcome that may have been insensitive to detect clinically important changes. Rituximab did not alleviate symptoms or disease activity in patients with pSS at week 24, although it alleviated some symptoms at earlier time points.

    ABSTRACT: Follicular helper T cells (Tfh), which play a pivotal role in B cell activation and differentiation in lymphoid structures, secrete IL-21 whose augmented secretion is a hallmark of several autoimmune diseases. To decipher the cellular and molecular interactions occurring in salivary glands of patients suffering from primary Sjögren's syndrome (pSS), we investigated whether salivary gland epithelial cells (SGECs) were capable to induce Tfh differentiation. Co-cultures of naïve CD4(+) T cells and SGECs from both patients with pSS and controls were performed. Here, we report that IL-6 and ICOSL expression by SGECs contributes to naïve CD4(+) T differentiation into Tfh cells, as evidenced by their acquisition of a specific phenotype, characterized by Bcl-6, ICOS and CXCR5 expression and IL-21 secretion, but also but by their main functional feature: the capacity to enhance B lymphocytes survival. We demonstrated an increase of serum IL-21 with systemic activity. Finally, we analyzed the potential occurrence of a genetic association between IL-21 or IL-21R gene polymorphisms and pSS or elevated IL-21 secretion. This study, which demonstrates a direct induction of Tfh differentiation by SGECs, emphasizes a yet unknown pathogenic role of SGECs and suggests that Tfh and IL-21 might be relevant biomarkers and/or therapeutic targets in primary Sjögren's syndrome.

    ABSTRACT: Lymphocytic infiltration of different exocrine and non-exocrine epithelia is the pathological hallmark of primary Sjögren's syndrome, whereas involvement of salivary and lachrymal glands with the clinical counterpart of dry eye and dry mouth are the predominant features of the disease, together with fatigue and musculoskeletal pain. In addition, systemic manifestations, like arthritis, skin vasculitis, peripheral neuropathy, glomerulonephritis, may also be present in a consistent number of patients. As result, clinical features in SS can be divided into two facets: the benign subjective but disabling manifestations such as dryness, pain and fatigue, and the systemic manifestations. In the past decades, great efforts have been made to develop valid tools for the assessment of these both facets. Disease specific questionnaires such as Profile of Fatigue and Discomfort (PROFAD) and Sicca Symptom Inventory (SSI) have been proposed for evaluation of patients' symptoms, whereas different composite indexes have been suggested for the assessment of systemic disease activity. After that, an international project supported by EULAR, emerged to develop consensus disease activity indexes: the EULAR Sjögren's Syndrome Patients Reported Index (ESSPRI), and the EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI), a systemic activity index to assess systemic manifestations. Both EULAR indexes have been developed in an international collaboration to be consensual. Both indices have now been validated in a large independent international cohort. They both have been shown to be feasible, valid and reliable instruments. Also, we have found that these two scores did not correlate, suggesting that these two indexes assess two different disease components that poorly overlap, but were complementary. The sensitivity to change of both scores has been assessed, they are both able to detect change, however, ESSDAI score, like other systemic score, is more sensitive to change than ESSPRI and other patient scores. Current work is ongoing to define disease activity levels and clinically important changes for defining significant clinical improvement with the systemic score ESSDAI, and ESSPRI. We hope that this increased knowledge on the way to assess patients with primary SS, along with the emergence of new targeted therapy, will put a great input in the improvement of conduction of clinical trials in pSS.

    ABSTRACT: MicroRNAs (miRNAs) have emerged as key players in the degradation of target mRNAs. They have been associated with diverse biological processes, and recent studies have demonstrated that miRNAs play a role in inflammatory responses. The identification of miRNA and their corresponding messenger RNA (mRNA) targets can therefore be very helpful. In this chapter, we first overview the field of miRNAs and then show the fundamental techniques for the identification of miRNAs and confirmation of their role on target mRNAs.

    ABSTRACT: Objective Patients with primary Sjögren's syndrome (SS) are at greater risk of developing lymphoma. This study was undertaken to evaluate whether the Fms-like tyrosine kinase 3 ligand (Flt-3L) might be associated with lymphoma in primary SS. Methods Serum levels of Flt-3L were measured in 369 patients with primary SS from the French Assessment of Systemic Signs and Evolution of Sjögren's Syndrome study cohort and in 10 patients with primary SS at the time of lymphoma diagnosis in an Italian cohort. Associations between increased levels of Flt-3L and a history of lymphoma, history of previously diagnosed criteria related to a high risk of lymphoma, and greater extent of disease activity were evaluated. ResultsAmong patients with primary SS, higher levels of Flt-3L were significantly associated with a history of lymphoma (P = 0.0001). Previous markers for risk of lymphoma development, such as presence of purpura, low levels of C4, presence of lymphocytopenia, low levels of IgM, high levels of β2-microglobulin, and a higher primary SS disease activity score, were all associated with higher levels of Flt-3L. The levels of Flt-3L were also increased in serum obtained from patients with primary SS at the time of lymphoma diagnosis. Furthermore, the Flt-3L levels were elevated in the serum of 6 patients up to 94 months (mean 46 months) prior to the diagnosis of lymphoma. Receiver operating characteristic curve analysis showed that an Flt-3L level of 175 pg/ml was the ideal cutoff value for demonstrating an association with lymphoma (specificity 97.5%, sensitivity 44%, negative predictive value 97%). Conclusion Flt-3L is associated with lymphoma in primary SS, and constitutes a good biologic marker. Higher levels of this cytokine are present several years before the diagnosis of lymphoma, and may be useful as a predictive marker of lymphoproliferative disorders in primary SS.

    ABSTRACT: Whipple disease is a rare infection caused by Tropheryma whipplei. Although patients commonly complain of osteoarticular involvement, musculoskeletal manifestations have been poorly described. We report cases of Whipple disease with rheumatic symptoms and describe their clinical presentation, modes of diagnosis, and outcomes. This retrospective multicenter study included patients with Whipple disease diagnosed and referenced between 1977 and 2011 in 10 rheumatology centers in France and Italy. Twenty-nine patients were included. The median age was 55 years. The median time to diagnosis from first symptoms was 5 years. Polyarthritis was the most frequent presentation (20/29), and was most often chronic, intermittent (19/29), seronegative (22/23), and nonerosive (22/29). In all cases, the symptoms had led to incorrect diagnosis of inflammatory rheumatic disease and immunosuppressants, including biotherapy, were prescribed in most cases (24/29) without success. The diagnosis of Whipple disease was made by histological analysis, molecular biology tests, or both in 21%, 36%, and 43% of the cases, respectively. Duodenal biopsies were performed in most cases (86%). Synovial biopsies were performed in 18% of cases, but all contributed to diagnosis. The clinical outcomes after antibiotic therapy were good for all patients. Polyarthritis is the main feature observed in cases of Whipple disease; it is seronegative and associated with general and gastrointestinal symptoms. The molecular analysis of duodenal tissue and/or other tissues remains the method of choice to confirm the diagnosis. Reducing the time to diagnosis is important because severe late systemic and fatal forms of the disease may occur.

    ABSTRACT: Primary Sjögren's syndrome (pSS) is a chronic autoimmune disease characterized by a lymphocytic exocrinopathy. However, patients often have evidence of systemic autoimmunity, and they are at markedly increased risk for the development of non- Hodgkin's lymphoma. Similar to other autoimmune disorders, a strong interferon (IFN) signature is present among subsets of pSS patients, although the precise etiology remains uncertain. NCR3/NKp30 is a natural killer (NK)-specific activating receptor regulating the cross talk between NK and dendritic cells and type II IFN secretion. We performed a case-control study of genetic polymorphisms of the NCR3/NKp30 gene and found that rs11575837 (G>A) residing in the promoter was associated with reduced gene transcription and function as well as protection to pSS. We also demonstrated that circulating levels of NCR3/NKp30 were significantly increased among pSS patients compared with controls and correlated with higher NCR3/NKp30 but not CD16-dependent IFN-γ secretion by NK cells. Excess accumulation of NK cells in minor salivary glands correlated with the severity of the exocrinopathy. B7H6, the ligand of NKp30, was expressed by salivary epithelial cells. These findings suggest that NK cells may promote an NKp30-dependent inflammatory state in salivary glands and that blockade of the B7H6/NKp30 axis could be clinically relevant in pSS.

    ABSTRACT: Sjögren's syndrome is a frequent autoimmune disease but its diagnostis is sometimes diffcult and delayed, because of miscellaneous symptoms. The most frequent clinical features include oral and ocular dryness, asthenia and pain. However, extraglandular manifestations concern one third of patients and severe complications, such as lymphoma, can reveal the disease. American European Consensus Group Criteria are used in current practice. They take into account subjective and objective clinical parameters and immunological and histological criteria. New criteria, recently proposed by the ACR, take into account objective ocular dryness, salivary lymphocytic infiltrates and the presence of immunological abnormalities (antinuclear and rheumatoid factors or anti-SSA/SSB). Primary Sjögren's syndrome must continue to benefit from a consensual diagnostic approach to ensure the quality of basic and clinical research and the applicability of their results to all patients. A group of international experts are currently working to reach a new consensus for the diagnosis of the disease.

    ABSTRACT: To analyze the clinical and immunological characteristics at enrollment in a large prospective cohort of patients with primary Sjögren's syndrome (pSS) and to investigate the association between serum BAFF, beta2-microglobulin and free light chains of immunoglobulins and systemic disease activity at enrollment. Three hundred and ninety five patients with pSS according to American-European Consensus Criteria were included from fifteen centers of Rheumatology and Internal Medicine in the "Assessment of Systemic Signs and Evolution of Sjögren's Syndrome" (ASSESS) 5-year prospective cohort. At enrollment, serum markers were assessed as well as activity of the disease measured with the EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI). Patient median age was 58 (25(th)-75(th): 51-67) and median disease duration was 5 (2-9) years. Median ESSDAI at enrollment was 2 (0-7) with 30.9% of patients having features of systemic involvement. Patients with elevated BAFF, beta2-microglobulin and kappa, lambda FLCS had higher ESSDAI scores at enrollment (4 [2]-[11] vs 2 [0-7], P = 0.03; 4 [1]-[11] vs 2 [0-7], P< 0.0001); 4 [2]-[10] vs 2 [0-6.6], P< 0.0001 and 4 [2-8.2] vs 2 [0-7.0], P = 0.02, respectively). In multivariate analysis, increased beta2-microglobulin, kappa and lambda FLCs were associated with a higher ESSDAI score. Median BAFF and beta2-microglobulin were higher in the 16 patients with history of lymphoma (1173.3(873.1-3665.5) vs 898.9 (715.9-1187.2) pg/ml, P = 0.01 and 2.6 (2.2-2.9) vs 2.1 (1.8-2.6) mg/l, P = 0.04, respectively). In pSS, higher levels of beta2-microglobulin and free light chains of immunoglobulins are associated with increased systemic disease activity.

    ABSTRACT: Background. Primary Sjögren's syndrome (PSS) is a frequent systemic autoimmune disease. In this study, we aimed to explore the cognitive impairment and the correlations with brain MRI. Methods. Twenty-five patients (mean age 55 ± 11.8 years, 21 females) with PSS were prospectively selected and tested with a French translation of the Brief Repeatable Battery for Neuropsychological Examination. The results were compared with the scores for 25 matched patients with multiple sclerosis (MS) and 25 controls. Brain lesions were assessed by brain MRI using the Wahlund classification. Results. Fifteen of the 25 PSS patients (60%) presented with cognitive disorders versus 19/25 MS patients (76%). Five patients had dementia in the PSS group. Speed of information processing, attention, immediate and long-term memory, and executive functions were frequently impaired. The mean duration of cognitive complaints was 5.6 ± 6.1 years, and the mean duration of PSS was 15.8 ± 14.0 years. A trend towards a correlation was found between the severity of cognitive impairment and the degree of white matter lesions (WML) (P = 0.03, rho = 0.43). Conclusion. Cognitive impairment-mild or dementia-exists in patients with PSS. Further MRI studies are needed to better understand the precise neural basis of cognitive impairment in PSS patients.

    ABSTRACT: Background There have been few studies on muscle injury caused by cytotoxic agents used in cancer. In particular, only four cases of muscle manifestations have been reported in patients who received gemcitabine as single chemotherapy without adjuvant radiotherapy. In only one of these observations was gemcitabine considered to be the causative agent. Methods We report the case of a patient without comorbidity treated with gemcitabine monotherapy for 2 months for pancreatic adenocarcinoma who developed a proximal motor deficiency of the lower limbs and myolysis (creatinine kinase 1858 U/L) associated with an erythema of both thighs. Results Muscle MRI revealed the presence of edema on both quadriceps muscles. A muscle biopsy showed post necrotic regeneration and significant vascular proliferation. Only three small inflammatory infiltrates were observed while expression of the major histocompatibility complex class I in muscle fibers was normal. There was no recurrence of cancer, anti-TIF-1γ antibodies tested negative and discontinuation of gemcitabine, without further treatment, resulted in complete disappearance of symptoms. Conclusions The present observation suggests that gemcitabine monotherapy without adjuvant radiotherapy can cause myopathy through vascular lesions, a mechanism which also underlies the more common side effects of this treatment. These findings have obvious therapeutic implications.

    ABSTRACT: B lymphocytes might play a pathogenic role in dermal fibrosis in systemic sclerosis (SSc). B-cell activating factor (BAFF), a key cytokine for B-cell activation, is increased in the serum and the skin of patients with SSc. However, the ability of B cells directly to stimulate dermal fibroblasts and the role of BAFF are not fully understood. We therefore investigated the involvement of B cells and BAFF in the expression of collagen and profibrotic markers by dermal fibroblasts. Cocultures of blood B cells from healthy blood donors and normal or SSc dermal fibroblasts stimulated with anti-IgM and BAFF were performed. Alpha-SMA, TIMP1, MMP9, COL1A1, COL1A2, and COL3A1 mRNA expression were determined by quantitative RT-PCR. Soluble collagen, BAFF, IL-6, IL-1β, TGF-β1, and CCL2 protein secretion were assessed. Coculture of blood B cells and dermal fibroblasts isolated from SSc patients induced IL-6, TGF-β1, CCL2, and collagen secretion, as well as Alpha-SMA, TIMP1, and MMP9 expression in dermal fibroblasts. Transwell assays demonstrated that this induction was dependent on cell-cell contact. Addition of anti-IgM and BAFF to the coculture increased IL-6, CCL2, TGF-β1, and collagen secretion. B cell- and BAFF-induced collagen secretion was highly reduced by anti-TGF-β1 antibodies. Our results showed for the first time a direct role of B cells on the production of collagen by dermal fibroblasts, which is further enhanced by BAFF. Thus, these results demonstrate a new pathogenic role of B cells and BAFF in fibrosis and systemic sclerosis.

    ABSTRACT: A new approach for the classification of patients with Sjögren's syndrome (SS) has been recently proposed. Although these new criteria substantially differ from the American European Consensus Group criteria, which have represented the gold standard for the last decade, when compared with each other the two sets show a high statistical degree of agreement. However, the fact that two different criteria to classify patient with SS could be available may introduce some additional difficulties in the scientific communication, making cohorts of patients selected by using different methods less than completely equivalent, and the results of epidemiological studies and therapeutic trials not entirely comparable. Consequently, to reach a consensus agreement on universally accepted classification criteria for SS seems to be a very desirable objective.

    ABSTRACT: OBJECTIVES: To evaluate the efficacy and safety of rituximab in patients with primary Sjögren's syndrome (pSS). METHODS: The AutoImmune and Rituximab registry has included 86 patients with pSS treated with rituximab, prospectivey followed up every 6 months for 5 years. RESULTS: Seventy-eight patients with pSS (11 men, 67 women), who already had at least one follow-up visit, were analysed. Median age was 59.8 years (29-83), median duration of disease was 11.9 years (3-32). Indications for treatment were systemic involvement for 74 patients and only severe glandular involvement in four patients. The median European Sjögren's Syndrome disease activity index (ESSDAI) was 11 (2-31). 17 patients were concomitantly treated with another immunosuppressant agent. Median follow-up was 34.9 months (6-81.4) (226 patient-years). Overall efficacy according to the treating physician was observed in 47 patients (60%) after the first cycle of rituximab. Median ESSDAI decreased from 11 (2-31) to 7.5 (0-26) (p<0.0001). Median dosage of corticosteroid decreased from 17.6 mg/day (3-60) to 10.8 mg/day (p=0.1). Forty-one patients were retreated with rituximab. Four infusion reactions and one delayed serum sickness-like disease resulted in rituximab discontinuation. Three serious infections (1.3/100 patient-years) and two cancer-related deaths occurred. CONCLUSIONS: In common practice, the use of rituximab in pSS is mostly restricted to patients with systemic involvement. This prospective study shows good efficacy and tolerance of rituximab in patients with pSS and systemic involvement.

    ABSTRACT: OBJECTIVE: To evaluate the efficacy and safety of rituximab (RTX) in several subsets of spondyloarthritis (SpA) using the data of the AIR (Autoimmunity and Rituximab) registry. METHODS: All patients receiving RTX for SpA, and prospectively included in the AIR registry from September 2005 to September 2010, were retrospectively analyzed. The response to treatment was evaluated by the Bath Ankylosing Spondylitis Disease Activity Index for axial disease, joint count for peripheral disease, and C-reactive protein reduction. RESULTS: Among the 595 patients included in the AIR registry, 26 patients with SpA from 13 centers were reported: ankylosing spondylitis (10), undifferentiated SpA (7), and psoriatic arthritis (9). Mean disease duration was 8.8 years (range 1-40). The extraarticular features found were psoriasis, 12 cases; uveitis, 4 cases; and Crohn's disease, 3 cases. The mean number of disease-modifying antirheumatic drugs before RTX was 2.4; previous anti-tumor necrosis factor (TNF) agents were taken in 23 cases. The mean number of RTX courses was 1.5 (range 1-5), with a total of 35.6 patient-years. Efficacy was noted in 11/23 cases: 3 out of 3 anti-TNF-naive patients and 8 out of 20 anti-TNF nonresponder patients. No predictive factors of response could be identified, particularly in diagnosis subsets or clinical presentation (axial or peripheral). CONCLUSION: In this nationwide study of several subsets of SpA, RTX had only a moderate efficacy that was more marked in patients who were anti-TNF-naive.

    ABSTRACT: To identify a specific pattern of serum cytokines that correlates with the diagnosis, activity and severity of rheumatoid arthritis (RA) in patients with early RA as well as with the level of serum markers of B cell activation. Serum interleukin (IL)-1β, IL-1 receptor antagonist (IL1-Ra), IL-2, IL-4, IL-6, IL-10, IL-17, IL-21, monocyte chemotactic protein 1 (MCP-1), tumour necrosis factor α and interferon γ levels were measured in the (ESPOIR) Etude et Suivi des POlyarthrites Indifférenciées Récentes early arthritis cohort, which included patients with at least two swollen joints for >6 weeks and <6 months, and no previous corticosteroids or disease-modifying antirheumatic drugs. Serum cytokine levels were compared between patients who met the 1987 American College of Rheumatology criteria for RA (n=578) or had undifferentiated arthritis (UA, n=132) at the 1-year follow-up visit. Serum IL-6 and IL-21 were the only cytokines that discriminated RA from UA on univariate analysis. IL-6 level was associated with RA, whereas erythrocyte sedimentation rate and C-reactive protein were not. Higher proportions of rheumatoid factor and anticyclic citrullinated protein (CCP) positivity, levels of markers of B cell activation, and a higher frequency of rapid radiographic progression were observed in patients with RA with detectable IL-6 or IL-21. Multivariate analysis associated IL-6 and anti-CCP levels with radiographic erosions at enrolment with 1-year radiographic progression. Serum IL-6 concentration is greater in RA than in UA. Increase in serum IL-6 and IL-21 levels is associated with markers of B cell activation, and IL-6 is associated with radiographic progression in patients with RA.
