21050739 Severe chronic bronchiolitis as the presenting feature of primary Sjögren's syndrome. 2011 Jan Sjögren's syndrome is a frequent auto-immune disorder with a pulmonary location in almost 10% of the patients. Although bronchial involvement is very common, most patients only complain of cough and this involvement rarely results in severe symptoms or chronic respiratory failure are rarely observed. We describe here 5 patients with severe chronic bronchiolitis revealing primary Sjögren's syndrome. The lung involvement resulted in chronic bronchorrhea, recurrent sinusitis, diffuse bronchiolar nodules with bronchiectasis on the CT scan, and a severe obstructive airway pattern on lung function tests. Improvement was obtained in 4 patients with combination of inhaled corticosteroids, inhaled long acting beta-agonists, and a low dose of erythromycin.
20340022 Good clinical response to methotrexate treatment in a patient with fibroblastic rheumatism 2012 Jun Fibroblastic rheumatism (FR) is a rare disease first described by Chaouat (in Rev Rhum Mal Osteoartic 47:345-351, 1980) and is characterized by a combination of rheumatologic and dermatological manifestations. Rheumatologic features are symmetrical polyarthralgias with joint stiffness, associated with cutaneous nodules and sclerodactyly. Histology shows an increased number of fibroblasts and a marked dermal fibrosis. A large number of treatments have been tried, but all of them have shown an unpredictable effect on FR. We report a Brazilian case of FR showing a good clinical response to methotrexate treatment. This drug may be considered an effective treatment in FR.
22812260 [Characteristics of the patients with primary Sjögren's syndrome complicated with lymphom 2012 May OBJECTIVE: To improve the understanding of diagnosis and treatment of patients with primary The data of clinical features, laboratory Sjögren's syndrome (pSS) complicated with lymphoma. METHODS: findings, therapeutic response and follow-up of patients with primary Sjögren's syndrome complicated with lymphoma from January 2006 to January 2011 in our single center were retrospectively analyzed. RESULTS: Totally twelve inpatients with pSS complicated with lymphoma were diagnosed, which accounted for 1.29% of newly-diagnosed lymphoma inpatients during the same period. The characteristic immunologic changes were hyperimmunoglobulinemia, hypocomplementemia and decrease of CD4 T cell number. In our study, non-Hodgkin's lymphoma (NHL) was the most common type, and the main pathological subtype was diffuse large B cell lymphoma (DLBCL). Most of the patients were in advanced stages, Ann Arbor stage IIl-IV, at diagnosis. Extranodal involvement was common, most frequently in the livers and the lungs. All of the patients received combination chemotherapy. Most of the NHL patients received CHOP/R-CHOP-like regimens, and the Hodgkin's lymphoma (HL) patient received AVD regimen. The median follow-up time was 27 months (range 1-56 months). In terms of median survival time and overall survival there were no statistical significant differences between both low C3 and low C4 group and control group (P > 0.05). In terms of median survival time and overall survival there were no statistical significant differences between rituximab treatment group and control group (P > 0.05). CONCLUSION: The patients with pSS complicated with lymphoma were not uncommon clinically. Hypocomplementemia could not be identified as a risk factor for the prognosis of pSS complicated with lymphoma in our study. Although expected prognosis of these patients was unfavorable, we found that treatment with rituximab combination chemotherapy could not improve the therapeutic effects and survival of patients with pSS complicated with lymphoma.
22322207 Correlation of serum CX3CL1 level with disease activity in adult-onset Still's disease and 2012 May To investigate the characteristics of patients with adult-onset Still's disease (AOSD), serum cytokines and chemokines were measured to examine their associations with systemic manifestations of AOSD, especially hemophagocytic syndrome (HPS). Nineteen patients diagnosed with AOSD were enrolled. Serial serum samples were obtained from patients with AOSD in both active and inactive stages and controls. The concentrations of cytokines and chemokines, including IL-18, soluble IL-2 receptor (sIL-2R), CX3CL1, CXCL8, CXCL10, CCL2, and CCL3, were determined using enzyme-linked immunosorbent assay. Multivariate analysis was used to evaluate the correlations among serum chemokine levels, disease activity, and the clinical features of AOSD. Significantly higher serum levels of all cytokines and chemokines were observed in patients with active, untreated AOSD than in controls. The level of CX3CL1, but not other chemokines, was elevated in AOSD patients and was positively correlated with clinical activity and the levels of CRP, ferritin, IL-18, and sIL-2R. Among the 19 patients with AOSD, four patients also had HPS. Serum CX3CL1 and ferritin were significantly higher in AOSD patients with HPS than in those without HPS. The serum CX3CL1 level may be used as a clinical marker to assess the disease activity of AOSD, and high serum CX3CL1 and ferritin in patients with AOSD reflected the presence of HPS. The association between the chemokine profile and distinct clinical manifestations or various patterns of disease progression indicates that the pathogenesis of AOSD is heterogeneous.
21903371 Small airway disease associated with Sjögren's syndrome: clinico-pathological correlation 2011 Dec BACKGROUND: Relationships among clinical, physiological, imaging and pathological findings of small airway disease associated with Sjögren's syndrome have remained unclear. SUBJECTS AND METHODS: We retrospectively studied 14 patients who underwent surgical lung biopsy and who were diagnosed with small airway disease associated with primary or secondary Sjögren's syndrome. We compared clinical, bronchoalveolar lavage, physiological, imaging and pathological findings between primary and secondary Sjögren's syndrome. We scored HRCT and pathological abnormalities and investigated correlations among physiological, HRCT and pathological data, changes in physiological parameters and in HRCT scores after two years of treatment, as well as correlations between these values and pathological scores. RESULTS: Bronchoalveolar lavage fluid, physiological, imaging and pathological findings of the airways did not significantly differ between primary and secondary Sjögren's syndrome. Air trapping on HRCT negatively correlated with MEF50 and MEF25. Although lymphoid cell infiltration and peribronchiolar fibrosis were the most common pathologies, constrictive change scores correlated negatively with MEF50 and MEF25, positively with air trapping scores and negatively with improvements after therapy in MEF(50), MEF(25) and air trapping. CONCLUSIONS: Constrictive change was the most significant determinant of physiological and imaging presentations and of changes in these factors after therapy for small airway disease associated with Sjögren's syndrome.
21860576 A case of necrotizing keratoscleritis in primary Sjogren's syndrome. 2011 Aug We report on a case of necrotizing keratoscleritis in primary Sjogren's syndrome. A 66-year-old female patient who was complaining of ocular pain, tearing and decreased vision in her right eye for the previous two days was admitted to our hospital. Visual acuity in the right eye was hand movement, and initial examination showed a 3.0 × 1.8 mm uveal mass bulging through a corneoscleral melting site in the nasal region of the right eye. Positive anti-nuclear antibody was identified at a titer of 1:320 with a speckled pattern, and both Sjogren's syndrome A and Sjogren's syndrome B antibody tests were positive, with titers >200 U/mL. A technetium 99m pertechnetate salivary scan revealed chronic sialoadenitis in the submandibular glands. We diagnosed the lesion as necrotizing keratoscleritis due to primary Sjogren's syndrome. A corneoscleral patch graft was performed, followed by immunosuppression including oral cyclosporin and topical prednisolone. During a follow-up period of 12 months, the corneoscleral graft was well maintained with no recurrence.
21369848 Anti-Ma2/Ta antibodies in a woman with primary lateral sclerosis-like phenotype and Sjögr 2011 Oct Anti-Ma2/Ta antibodies are rare paraneoplastic antibodies, which are mostly associated with limbic encephalitis in male patients with testicular cancer. We report on a 50-year-old woman with a pure progressive spastic paraparesis. Next, she was diagnosed as having a Sjögren syndrome, with serological positivity for anti-SS-Ro antibodies. The patient's serum and cerebrospinal fluid samples were positive for anti-Ma2/Ta antibodies, which were also proved to be intrathecally produced. These findings, and the coexistence of systemic autoimmunity, led us to treat the patient with corticosteroids first, and then with plasma exchange. Neurological symptoms scarcely responded to both the therapies. The search for cancer was negative up to 4 years after the disease onset. Our case expands the spectrum of clinical syndromes associated with anti-Ma2/Ta antibodies.
21338929 The isolated talonavicular arthrodesis. 2011 Mar Based on a high percentage of good results, retrospective studies strongly suggest that isolated talonavicular arthrodesis provides efficient pain relief and functional improvement in case of talonavicular arthritis in rheumatoid arthritis, primary or posttraumatic arthritis, flexible acquired flatfoot deformity, residual dorsolateral subluxation of the talonavicular joint after surgical treatment of clubfoot, and some neurologic disorders. However, prospective trials with rigorous methodology are required to establish evidence of efficacy for this procedure. Well-designed biomechanical studies have demonstrated the key role of the talonavicular joint in the complex hindfoot motion and may serve as baseline for further prospective studies.
22537486 Anti-proliferative effects of Salacia reticulata leaves hot-water extract on interleukin-1 2012 Apr 26 BACKGROUND: Salacia reticulata (SR) is a plant native to Sri Lanka. In ayurvedic medicine, SR bark preparations, taken orally, are considered effective in the treatment of rheumatism and diabetes. We investigated the ability of SR leaves (SRL) to inhibit in vitro the interleukin-1β (IL-1β)-activated proliferation of synoviocyte-like cells derived from rheumatoid arthritis model mice. FINDINGS: Inflammatory synovial tissues were harvested from type II collagen antibody-induced arthritic mice. From these tissues, a synoviocyte-like cell line was established and named MTS-C H7. To determine whether SRL can suppress cell proliferation and gene expression in MTS-C H7 cells, fractionation of the SRL hot-water extract was performed by high-performance liquid chromatography (HPLC), liquid-liquid extraction, sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE), and protease digestion.The 50% inhibitory concentration of the SRL hot-water extract against MTS-C H7 cells proliferation was ~850 μg/mL. Treatment with a low dose (25 μg dry matter per millilitre) of the extract inhibited IL-1β-induced cell proliferation and suppressed the expression of the matrix metalloproteinase (MMP) genes in MTS-C H7 cells. Various polyphenolic fractions obtained from HPLC and the fractions from liquid-liquid extraction did not affect cell proliferation. Only the residual water sample from liquid-liquid extraction significantly affected cell proliferation and the expression of MMP genes. The results of SDS-PAGE and protease digestion experiment showed that low molecular weight proteins present in SRL inhibited the IL-1β-activated cell proliferation. CONCLUSIONS: We surmised that the residual water fraction of the SRL extract was involved in the inhibition of IL-1β-activated cell proliferation and regulation of mRNA expression in MTS-C H7 cells. In addition, we believe that the active ingredients in the extract are low molecular weight proteins.
21862108 New onset of uveitis during anti-tumor necrosis factor treatment for rheumatic diseases. 2011 Dec Uveitis may be associated with various inflammatory diseases. Previous reports suggested that tumor necrosis factor (TNF) blockers, especially anti-TNF monoclonal antibodies, may reduce the incidence of uveitis flares in some inflammatory diseases. Under these circumstances, de novo occurrence, ie, new onset of the first episode of uveitis under anti-TNF therapy, is uncommon. OBJECTIVES: The aim of this study was to collect cases of new onset of uveitis under anti-TNF therapy, using a nationwide network, to describe these cases, and to gather with cases reported in the literature. METHODS: All French rheumatologists, pediatric rheumatologists, and internal medicine practitioners registered on the Club Rhumatismes et Inflammation web site were contacted in an attempt to declare the cases of new onset of uveitis, diagnosed by an ophthalmologist, in patients treated with TNF blockers. The analysis of the literature was performed through PubMed database and manual research. RESULTS: Thirty-one cases were recorded, 19 men, mean age 43 (5-70) years, occurring in ankylosing spondylitis (19 cases), psoriatic arthritis (4 cases), rheumatoid arthritis (6 cases), juvenile idiopathic arthritis (2 cases). The TNF blocker at the time of uveitis was etanercept 23 times, adalimumab 3 times, infliximab 5 times, with a mean total duration of exposure to anti-TNF agents of 27 (4-96) months at uveitis occurrence. Most of the patients were good responders to TNF blockers at the time of uveitis onset. Analysis of the literature revealed 121 similar cases published in English. CONCLUSION: Uveitis occurs de novo under anti-TNF therapy mainly in spondyloarthropathies, but also in rheumatoid arthritis and juvenile idiopathic arthritis patients and more frequently under etanercept.
21553767 Shoulder arthroplasty for the treatment of rotator cuff insufficiency. 2011 Irreparable rotator cuff tendon tears result from chronic tears, failed cuff repairs, and fracture sequelae and occur in patients with rheumatoid arthritis. The management of patients with cuff tear arthropathy can be challenging. When pain is severe and function is poor, surgical options include hemiarthroplasty, bipolar arthroplasty, extended head arthroplasty, arthroplasty with tendon transfer, reverse shoulder arthroplasty, and fusion. A review of the literature shows good pain relief with hemiarthroplasty in carefully selected patients; however, the reverse prosthesis has been found to better restore motion in patients with pseudoparalysis, failed fracture treatment, or a failed prosthesis.
21904564 Antirheumatoid Arthritis Activities and Chemical Compositions of Phenolic Compounds-Rich F 2012 Urtica atrichocaulis, an endemic plant to China, is commonly used to treat rheumatoid arthritis even though its pharmaceutical activities and chemical constituents were not studied. Herein, we reported our investigations on the chemical compositions of the phenolic compounds-rich fraction from U. atrichocaulis (TFUA) and their antirheumatoid arthritis activities. We found that the TFUA significantly inhibited the adjuvant-induced rats arthritis, carrageenin-induced rats paw edema, cotton pellet-induced mice granuloma, and the acetic acid-induced mice writhing response. Our phytochemical investigations on the TFUA resulted in the first-time isolation and identification of 17 phenolic constituents and a bis (5-formylfurfuryl) ether. The extensive HPLC analysis also revealed the chemical compositions of TFUA. Our further biological evaluation of the main phenolic components, individually and collectively, indicated that the antirheumatoid arthritis activities of TFUA were the combined effect of multiple phenolic constituents.
22933832 Atherosclerosis in juvenile idiopathic arthritis. 2012 Atherosclerosis is a chronic inflammatory disease of the arteries. Clinical consequences of the atherosclerotic process occur in the adult population, however atherosclerotic process begins in childhood. The classic risk factors for atherosclerosis include obesity, dyslipidaemia, age, gender or family history. In recent years, attention has been drawn to the similarity between atherosclerotic inflammatory processes and inflammatory changes in the course of systemic connective tissue disease, in particular systemic lupus etythematosus (SLE) or rheumatoid arthritis (RA). There is also observed the similarity of the pathogenetic background of development of atherosclerosis and juvenile idiopathic arthritis (JIA). Elevated levels of pro-inflammatory cytokines are observed in the course of juvenile idiopathic arthritis. Also homocysteine concentrations, which may play a significant role in the development of atherosclerotic lesions, are observed higher in patients with JIA. Some studies revealed higher carotid intima-media thickness (IMT) index values in children with JIA. In view of the fact that atherosclerotic process begins as early as in childhood, the introduction of appropriate preventive measures in children is a matter of utmost importance.
21511549 Inflammatory posterior interosseous nerve palsy in a patient with psoriatic arthropathy. 2011 Aug Psoriasis is a chronic, relapsing, inflammatory skin disorder with a strong genetic basis. Five patterns of psoriatic arthritis have been identified: asymmetrical oligoarticular arthritis, symmetrical polyarthritis, distal interphalangeal arthropathy, arthritis mutilans and spondylitis with or without sacroiliitis. Extra-articular disease is uncommon. We report a rare case of an inflammatory posterior interosseus nerve palsy in a patient with known psoriatic arthropathy, where investigation warranted medical treatment over a surgical approach. The commonest cause of posterior interosseus nerve palsy is entrapment at the proximal forearm. Other possible aetiologies include extension of elbow synovitis as described in rheumatoid arthritis, trauma eg. Monteggia fractures, tumours and iatrogenic injuries. We discuss the diagnostic dilemma and the management issues for upper limb surgeons.
22644323 Downregulation of the inflammatory response by CORM-3 results in protective effects in a m 2012 Jul CO-releasing molecules (CORMs) are a new class of drugs able to release small amounts of CO in biological systems. We have shown previously that one of these molecules, CORM-3, exerts anti-inflammatory effects in animal models. The aim of this study was to assess the effects of CORM-3 on bone metabolism in a model of postmenopausal rheumatoid arthritis osteoporosis. Ovariectomy was followed by collagen-induced arthritis in female DBA-1/J mice. Animals showing arthritis on day 22 after immunization were then randomized into control and treatment groups. CORM-3 was administered at 10 mg/kg, intraperitoneally, once a day. Alendronate was administered at 100 μg/kg, orally, once a day. On days 36 and 50 after immunization, animals were killed and tissues analyzed. The arthritic score was significantly reduced by CORM-3 but not by alendronate treatment. Histopathological analyses indicated that both compounds reduced cellular infiltration and cartilage degradation. Local bone erosion and reduction in TNFα levels were seen for CORM-3 on day 50 and for alendronate on day 36. Serum levels of COMP, IL-6, MMP-3, CTX-I, alkaline phosphatase, and osteocalcin were decreased by both treatments, whereas TNFα levels were reduced by CORM-3 and TRAP-5b by alendronate. Micro-computed tomographic analysis showed protective effects on trabecular bone, which were more prominent for CORM-3 on day 36 and for alendronate on day 50. Our results suggest that CORMs represent a novel anti-inflammatory strategy to counteract joint bone erosion with partial protective effects on systemic bone loss in postmenopausal rheumatoid arthritis.
22008816 Active immunization against IL-23p19 improves experimental arthritis. 2011 Nov 21 INTRODUCTION: IL-23 is a pro-inflammatory cytokine essential for the differentiation of Th17 lymphocytes, a subtype of T lymphocyte implied in auto-immunity. IL-23 shares a subunit with IL-12, IL-12/23p40, and comprises a specific subunit, IL-23p19. We previously demonstrated that active immunization against entire TNF-α and against peptides of IL-1β was protective in animal models of rheumatoid arthritis. The aim of this study was to evaluate the effect of peptide-based vaccines targeting the IL-23p19 subunit in collagen-induced arthritis (CIA). METHODS: Using bioinformatics, the murine IL-23p19 subunit was modeled and two peptides were defined in the receptor interacting domain. Each peptide was coupled to keyhole limpet hemocyanin (KLH) to obtain two vaccines IL23-K1 and IL23-K2. Both vaccines were used for immunizations in incomplete Freund adjuvant (IFA) in groups of DBA/1 mice. Control groups received KLH or PBS at the same dates. CIA was induced by two subcutaneous injections of bovine type II collagen (CIIb), and the development of disease assessed during the next two months. Anti-CIIb and anti-IL-23 antibody levels were assessed by ELISA. Pro- and anti-inflammatory cytokines mRNA were quantified by qRT-PCR in the spleen and the synovium. T-cell populations in the spleen were evaluated by FACS analysis. RESULTS: The clinical scores showed that mice treated with IL23-K1 developed less arthritis than negative controls (p<0.05). Mice immunized with IL23-K1 produced more anti-IL-23 antibodies than those immunized with IL23-K2 (p<0.001). mRNA quantification showed that the IL23-K1 immunization led to an increase of IL-10 in the spleen (p<0.05 vs. KLH), without any effect on IL-17 level. Histological examination showed that IL23-K1 strongly protected against joint destruction and inflammation (p<0.01 vs. KLH and p<0.001 vs. PBS). T-cell populations in the spleen were not modified by IL-23 modulation. CONCLUSION: These data show that targeting IL-23p19 through a vaccination strategy is protective in CIA. This specific targeting of IL-23 might constitute a promising therapeutic approach to explore in rheumatoid arthritis.
22326205 Pathogenesis of Sjögren's syndrome: what we know and what we should learn. 2012 Aug Sjögren's syndrome (SS) or autoimmune epithelitis is a prototype autoimmune disorder with unique features: a broad clinical spectrum that extends from local exocrinopathy to systemic disease and lymphoma development, and an easy access to the inflamed tissues (minor salivary glands; MSG), which enables the investigators to study the autoimmune processes. The autoimmune lesion consists of lymphocytic infiltrates that develop around the ducts and vary in severity and composition. T cells (mainly CD4(+)) are the dominant lymphocytes in mild MSG lesions, whereas B cells in severe ones. Th1 cytokines predominate in SS infiltrates, albeit Th2 and Th17 responses have been also reported. Notably, increased infiltration by IL-18(+) cells has been associated with parotid gland enlargement and C4-hypocomplementemia, which are adverse prognostic factors for lymphoma development. Even though SS pathogenesis has not been fully revealed, several aspects have been delineated. Among them, the key role of MSG epithelia in the initiation and perpetuation of local autoimmune responses is well-established and involves the capacity of epithelial cells to mediate the recruitment, homing, activation, proliferation and differentiation of immunocytes. In addition, genetic features, including certain HLA phenotypes and polymorphisms in genes encoding cytokines or factors implicated in cytokine signaling, environmental (such as viruses) and hormonal factors are thought to participate in disease pathogenesis. Herein, the known aspects of SS pathogenesis, as well as unmet issues are discussed.
20809902 Clinical features of Sjogren's syndrome in patients with multiple sclerosis. 2011 Aug OBJECTIVES:   To assess the frequency of clinical features of Sjogren's syndrome (SS) in patients with multiple sclerosis (MS) receiving treatment with disease-modifying drugs (DMDs) or naïve to treatment and the possible association with clinical, cerebrospinal fluid (CSF) and magnetic resonance imaging (MRI) parameters. METHODS:   A multicentre cross-sectional observational study was designed, based on a structured neurologist-administered questionnaire to 440 patients. RESULTS:   Twenty-eight of 230 (12%) patients receiving treatment with DMDs (DMDs(+)) and 14 of 210 (6.6%) treatment-naïve patients (DMDs(-) ) showed clinical features of SS. Four primary SS were diagnosed, two of which were DMDs(+) and two were DMDs(-) . Sicca symptoms were significantly associated with higher EDSS scores (P = 0.018), a low frequency of gadolinium-enhanced MRI-positive lesions (P = 0.018) and cerebral disturbances (P = 0.001). CONCLUSIONS: Screening for the clinical features of SS should be performed in patients with MS both receiving treatment with immunomodulatory drugs and without therapy.
21627736 Marathon of eponyms: 19 Sjögren syndrome. 2011 Jul The use of eponyms has long been contentious, but many remain in common use, as discussed elsewhere (Editorial: Oral Diseases. 2009: 15; 185). The use of eponyms in diseases of the head and neck is found mainly in specialties dealing with medically compromised individuals (paediatric dentistry, special care dentistry, oral and maxillofacial medicine, oral and maxillofacial pathology, oral and maxillofacial radiology and oral and maxillofacial surgery) and particularly by hospital-centred practitioners. This series has selected some of the more recognized relevant eponymous conditions and presents them alphabetically. The information is based largely on data available from MEDLINE and a number of internet websites as noted below: the authors would welcome any corrections. This document summarizes data about Sjögren syndrome.
22682057 Attenuation of collagen-induced arthritis by orally available imidazoline-based NF-κB inh 2012 Jul 15 The pathogenesis of rheumatoid arthritis is mainly driven by NF-κB-mediated production of cytokines, such as TNF-α. We report herein that the orally available imidazoline-based NF-κB inhibitor, TCH-013, was found to significantly reduce TNF-α signaling and attenuate collagen antibody induced arthritis in BALB/c mice.
