24854756 | [Clinico-electrophysiological and pathological characteristics of neuropathy in Sjögren's | 2014 Mar 25 | OBJECTIVE: To summarize the clinical features, electrophysiological and neuropathological characteristics of peripheral nerves in patients with primary Sjögren's syndrome (SS). METHODS: We retrospectively analyzed the clinical, electrophysiological and neuropathological characteristics of 5 female SS patients with neuropathy complications undergoing electrophysiology and sural nerve biopsy at our department from January 2011 to June 2013. RESULTS: They had an age range of 20-75 years. The course of peripheral neuropathy ranged 0.5-60 months and the whole course 12-240 months. pSS-associated neuropathy included multiple mononeuropathy (n = 1), symmetrical axonal sensorimotor polyneuropathy (n = 1) and sensory ganglioneuronopathy (n = 3). All biopsies showed varying degrees of myelinated fiber loss. Three biopsies had axonal degeneration associated with demyelination. However, there was no formation of onion bulb regeneration or plexus. Necrotizing vasculitis was diagnosed in 2 cases. CONCLUSION: The manifestations of peripheral nerve n pSS include multiple mononeuropathy, axonal symmetric sensorimotor polyneuropathy and sensory gangioneuronopathy. Sural biopsy shows typical necrotizing vasculitis in some cases and myelinated fiber loss and axonal degeneration in others. The pathogenic mechanisms of neurological involvement in pSS remain unknown. However, vasculitis, ischemic and immunological insults resulting in sensory gangioneuronopathy have been described. | |
24252039 | Primary and secondary surveys on epidemiology of Sjögren's syndrome in Japan. | 2014 May | OBJECTIVE: To characterize the epidemiology of Sjögren's syndrome (SS), including prevalence, disease type, extra-glandular involvement, satisfaction of diagnostic criteria sets, and treatment used in Japan. METHODS: The Research Team for Autoimmune Diseases, the Research Program for Intractable Disease by the Ministry of Health, Labor and Welfare conducted primary and secondary surveys on epidemiology of SS in 2011. The primary survey covered 4,729 out of 14,095 Japan-wide Hospital Departments to investigate the prevalence of SS. The secondary survey encompassed 214 Hospital Departments that agreed to the survey, to characterize disease type, extra-glandular involvement, satisfaction of diagnostic criteria sets, and treatments. RESULTS: The number of patients with SS in Japan estimated by the primary survey was 68,483. The secondary survey involving data collected from 2,195 SS patients from 98 Hospital Departments showed that the mean age of patients was 60.8 ± 15.2 years, male/female ratio was 1/17.4, primary/secondary SS was about 60%/40% and glandular/extra-glandular form in primary SS was about 70%/25%. The satisfaction rate was 53.8% for the 1999 revised Japanese Ministry of Health criteria for the diagnosis of SS, 47.7% for the 2002 American-European Consensus Group classification criteria for SS and 49.6% for 2012 American College of Rheumatology classification criteria for SS. Corticosteroids were used by 752 of 2,195 patients (34%), immunosuppressants by 358 patients (16%), biologics by 68 patients (3%) and secretagogues by 695 patients (32%). CONCLUSION: The surveys provided valuable information on the epidemiology of SS including prevalence, disease type, extra-glandular involvement, satisfaction of diagnostic criteria sets and treatments used today in Japan. | |
25413736 | Severe hyperferritinemia--a clue for severe hepatitis in a patient with adult-onset Still' | 2016 Mar | A 19-year old previously healthy man developed the adult-onset Still's disease (AOSD) with high ferritin levels. Corticosteroids induced clinical remission with resolution of fever, arthritis, and rash. While tapering corticosteroids, the patient developed severe liver enzymes elevation, very high ferritin levels and, subsequently, acute liver failure. After other causes of liver disease (infections, metabolic, autoimmune hepatitis, lymphoma, and hemophagocytosis) were excluded, severe hepatitis was attributed to AOSD itself. Cyclosporine induced rapid normalization of liver enzymes and reduction in ferritin levels. Severe hepatitis and very high ferritin levels could be the only manifestation of disease activity in AOSD; therefore, monitoring of liver enzymes and ferritin levels is recommended even after resolution of the clinical symptoms of AOSD. Prompt initiation of cyclosporine can improve liver function and prevent progression to liver failure. | |
25288784 | Psychological profiles in patients with Sjögren's syndrome related to fatigue: a cluster | 2015 May | OBJECTIVE: Fatigue is a highly prevalent and debilitating symptom in the autoimmune disease SS. Although the disease process plays a role in fatigue, psychological factors may influence fatigue and the ability to deal with its consequences. Profiles of co-occurring psychological factors may suggest potential targets for the treatment of fatigue. The aim of this study was to identify psychological profiles in patients with SS and the accompanying levels of fatigue. METHODS: Three hundred patients with primary SS (mean age 57 years, 93% female) completed questionnaires on fatigue (multidimensional fatigue inventory), physical activity cognitions (TAMPA-SK), illness cognitions, cognitive regulation, emotion processing and regulation [Toronto Alexithymia Scale 20, Emotion Regulation Questionnaire (ERQ), Berkeley Expressivity Questionnaire], coping strategies (Brief COPE) and social support. RESULTS: Principal axis factor analysis (oblimin rotation) yielded six psychological factors: social support, negative thinking, positive thinking, emotional expressivity, avoidance and alexithymia (i.e. the inability to differentiate emotions). Using cluster analyses, these factors were grouped in four psychological profiles: functional (39%), alexithymic (27%), self-reliant (23%) and dysfunctional (11%). Irrespective of the psychological profile, the level of fatigue was substantially higher in patients than in the general population. Patients with a dysfunctional or an alexithymic profile reported more fatigue than those with a self-reliant profile. CONCLUSION: Our study in SS yielded four psychological profiles that were differentially associated with fatigue. These profiles can be used to examine determinants and prognosis of fatigue as well as the possibility of customizing cognitive behavioural interventions for chronic fatigue. | |
25076705 | Atypical presentation of systemic lupus erythematosus: parotitis and secondary Sjogren's s | 2014 Apr | Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by auto antibodies directed against self-antigens, immune complex formation and immune deregulations and may affect joints, skin, kidneys, heart, lungs, nervous system, and immune system. The onset can be variable and the symptoms can occur for many years. Parotitis as the initial manifestation of systemic lupus erythematosus (SLE) is a rare condition and can be associated with Sjogren's syndrome. In this article we present the case of a young patient who was diagnosed with Sjogren's syndrome retrospectively, after she met the criteria for SLE. | |
24882855 | Bone formation in psoriatic arthritis: a report from the GRAPPA 2013 Annual Meeting. | 2014 Jun | The simultaneous presence of bone erosions and bony spurs (osteophytes, enthesophytes) in the joints of patients with psoriatic arthritis (PsA) suggests that the disease leads to enhanced bone resorption as well as increased bone formation, the latter of which has not been observed in patients with rheumatoid arthritis. At the 2013 Annual Meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA), members heard an update on the current research into the cytokine signature in PsA and its effects on new bone formation. | |
25025869 | Antibodies specific for carbamylated proteins precede the onset of clinical symptoms in mi | 2014 | OBJECTIVE: The immune response to post-translationally modified antigens is a key characteristic of rheumatoid arthritis. Carbamylation is such a posttranslational modification. Recently, we demonstrated that autoantibodies recognizing carbamylated proteins are present in sera of rheumatoid arthritis. The molecular mechanisms underlying the break of tolerance and hence the induction of anti-CarP antibody responses are unknown as well as their appearance in mouse models for systemic arthritis. Therefore we analyzed their appearance in the mouse collagen-induced arthritis model. METHODS: collagen induced arthritis was induced by immunization with type II collagen in complete Freund's adjuvant. Arthritis severity was monitored by clinical scoring and anti-CarP antibody levels were determined by ELISA. RESULTS: Anti-CarP antibodies were detectable in mice with collagen induced arthritis. We did not detect ACPA in mice with collagen induced arthritis. The specificity of the antibodies for carbamylated proteins was confirmed by inhibition assays and immunoblotting. Injection with complete Freund's adjuvant without type II collagen could also induce anti-CarP antibodies, however, in mice with arthritis, the anti-CarP antibody response was stronger and developed more rapidly. The onset of collagen induced arthritis was preceded by an increase of anti-CarP IgG2a levels in the serum. CONCLUSION: In mice with collagen induced arthritis we did not observe an immune response against citrullinated antigens, but we did observe an immune response against carbamylated antigens. This anti-CarP response already appeared before disease onset, indicating that collagen induced arthritis can be used as an in vivo model to study anti-CarP antibodies. Our data also indicate that the tolerance to carbamylated proteins, in contrast to the response to citrullinated proteins, is easily broken and that arthritis boosts the immune response against these proteins. The anti-CarP response in mice with CIA can be used as a model for immune responses to post-translationally modified proteins. | |
23872253 | Wen Luo Yin inhibits angiogenesis in collagen-induced arthritis rat model and in vitro. | 2013 Sep 16 | ETHNOPHARMACOLOGICAL RELEVANCE AND AIM OF THE STUDY: Wen Luo Yin (WLY) is a traditional Chinese formula, which has the traditional use of scattering cold pathogen, draining dampness, freeing the flow of network vessels and relieving pains. It is extensively used in the treatment of rheumatoid arthritis (RA) patients for more than 2000 years, but its actions on angiogenesis of RA have not been clarified. The present study aims to determine the anti-angiogenic activity of WLY on collagen-induced arthritis (CIA) rat model and in human fibroblast-like synoviocytes of RA (HFLS-RA) and human umbilical vein endothelial cells (HUVEC). MATERIALS AND METHODS: For in vivo experiment, arthritis was induced by immunization with bovine II collagen in DA rats. Treatment with WLY (3.45, 6.9, 13.8 g/kg, p.o., daily), or vehicle began from day 1 to day 28 of first immunization. The arthritis score, arthritis incidence, microfocal computed tomography analysis and histopathology evaluation of inflamed joints were assessed. Angiogenesis was measured by synovial vessel density with immunohistochemistry and histomorphometric analysis in synovial membrane tissues of joints. For in vitro experiments, HFLS-RA and HUVEC were used. Assays to determine HFLS-RA migration and adhesion were performed in the presence of vascular endothelial growth factor (VEGF)165 or interleukin (IL)-1β and/or the WLY (8, 16, 32 mg/ml). Angiogenesis was assessed by measuring the migration, adhesion, and tube formation of HUVEC. Further the effect of treatment with WLY on expression levels of angiogenic activators in sera of CIA rats and in IL-1β-induced HFLS-RA were evaluated by enzyme linked immunosorbent assay. RESULTS: WLY significantly decreased the arthritis score and arthritis incidence, and inhibited inflammation, pannus formation, cartilage and bone destruction of inflamed joints in CIA rats. More interestingly, doses of 3.45-13.8 g/kg WLY could markedly reduce the capillaries, small, medium and large vessel density in synovial membrane tissues of inflamed joints. Moreover, WLY suppressed the VEGF-induced chemotactic migration of HFLS-RA and HUVEC, and inhibited matrigel-induced cell adhesion of them. It also disrupted tube formation of HUVEC on matrigel. Furthermore, WLY significantly reduced the expression of angiogenic activators including tumor necrosis factor-α, IL-1β, IL-17, VEGF, VEGFR, angiopoietin (Ang)-1, Ang-2 and Ang-2 receptor in sera of CIA rats and/or in IL-1β-induced HFLS-RA/HUVEC. CONCLUSIONS: Our data suggest for the first time that WLY posses the anti-angiogenic effect in RA both in vivo and in vitro by downregulating angiogenic activators. | |
23403612 | Shuangtengbitong tincture treatment of collagen-induced arthritis via downregulation of th | 2013 Feb | Rheumatoid arthritis (RA) is a chronic, systemic autoimmune disease and may lead to joint damage, synovial membrane destruction and cartilage and bone damage. RA is closely associated with increased expression of interleukin (IL)-6, IL-8, tumor necrosis factor-α (TNF-α) and nuclear transcription factor-κB (NF-κB). Therefore, inhibition of the expression of IL-6, IL-8, TNF-α and NF-κB is a promising strategy for the development of novel anti-RA therapies. The aim of this study was to investigate the effect of shuangtengbitong tincture (STBT) on the expression of IL-6, IL-8, TNF-α and NF-κB in synovial tissues of rats with collagen-induced arthritis (CIA). STBT as a clinical prescription created at Fujian University of Traditional Chinese Medicines (TCM) Affiliated People's Hospital has been shown to be clinically effective in the treatment of RA. The model of Wistar rats with CIA was created using bovine type II collagen. The two treatment groups with CIA were administered STBT (1 ml per time) or Votalin (∼1 cm per time) for ∼1 month continuously. Following treatment, STBT suppressed paw swelling significantly (P<0.05) compared with the model group. STBT also improved pathological changes, STBT-treated rats showed a significant improvement in synovial hyperplasia, inflammatory infiltration, cartilage and bone destruction and other symptoms. The protein expression levels of IL-6, IL-8, TNF-α and NF-κB were markedly suppressed in synovial tissues of STBT-treated and Votalin-treated rats. Our findings demonstrate for the first time that STBT markedly reduces paw swelling, improves pathological changes and increases the expression of IL-6, IL-8, TNF-α and NF-κB in synovial tissues of CIA rats, which may partially explain the anti-RA activity of STBT. | |
24746866 | The hand in systemic diseases other than rheumatoid arthritis. | 2014 Jun | This review outlines the skin, vascular and musculoskeletal symptoms affecting the hand during systemic inflammatory diseases other than rheumatoid arthritis. Skin lesions are diagnosed clinically and their symptomatology is documented through an extensive series of photographs. These conditions may require specific care before a surgical procedure can be performed. Vascular lesions are also diagnosed clinically and their symptomatology is described in detail. It is important to recognize that acrocyanosis is always benign. The surgeon should be able to distinguish between primary, but benign Raynaud's disease and secondary Raynaud's syndrome, which has a high risk of finger necrosis. Current preventative and curative treatments for finger necrosis are described. The clinical, radiological, progressive and therapeutic features of musculoskeletal lesions are reviewed, namely those associated with psoriatic arthritis, systemic sclerosis and lupus. | |
24044939 | The impact of primary Sjogren's syndrome on pregnancy outcome: our series and review of th | 2014 Feb | OBJECTIVE: Firstly, to investigate the pregnancy outcome of women with primary Sjogren's Syndrome (pSS) in a case-control study; secondly, to perform a review of the literature in order to clarify if the pregnancy outcome is affected by pSS and influenced by the disease clinical onset. METHOD OF STUDY: Thirty-four pregnancies with pSS and 136 controls were retrospectively collected. RESULTS: Six pregnancies occurred before the pSS diagnosis and 28 after the pSS diagnosis. Two cases were complicated by intrauterine atrio-ventricular block. A statistically significant increase of the rate of spontaneous abortions, preterm deliveries and cesarean section was found in pSS pregnancies. The mean neonatal birth weight and the mean neonatal birth weight percentile were significantly lower in the offspring of women with pSS in comparison to controls. Similar pregnancy outcome was observed in women with pSS diagnosis before and after the index pregnancy. CONCLUSIONS: Women with pSS experienced complicated pregnancies more frequently than controls, regardless of the onset of the symptoms, showing that the immunological disturbance is present throughout the reproductive life. | |
25294776 | Anti-inflammatory and joint protective effects of extra-virgin olive-oil polyphenol extrac | 2014 Dec | The consumption of extra virgin olive oil (EVOO) in Mediterranean countries has shown beneficial effects. A wide range of evidence indicates that phenolic compounds present in EVOO are endowed with anti-inflammatory properties. In this work, we evaluated the effects of EVOO-polyphenol extract (PE) in a model of rheumatoid arthritis, the collagen-induced arthritis model in mice. On day 0, DBA-1/J mice were immunized with bovine type II collagen. On day 21, mice received a booster injection. PE (100 and 200 mg/kg) was orally administered once a day from days 29 to 41 to arthritic mice. We have demonstrated that PE decreases joint edema, cell migration, cartilage degradation and bone erosion. PE significantly reduced the levels of proinflammatory cytokines and prostaglandin E2 in the joint as well as the expression of cyclooxygenase-2 and microsomal prostaglandin E synthase-1. Our data indicate that PE inhibits c-Jun N-terminal kinase, p38 and signal transducer and activator of transcription-3. In addition, PE decreases nuclear factor κB translocation leading to the down-regulation of the arthritic process. These results support the interest of natural diet components in the development of therapeutic products for arthritic conditions. | |
23710558 | Gynaecological symptoms and sexual disability in women with primary Sjögren's syndrome an | 2013 Sep | OBJECTIVES: This paper aims to investigate women with primary Sjögren's syndrome (pSS) and sicca syndrome (SS), focusing on the prevalence of disease-related symptoms and their impact on sexual ability, relationship, communication about sexuality with partner and health professionals (HP). METHODS: Sixty-two women with pSS and 33 with SS were assessed for sexual activity, relationship with partner, communication about sex; for physical disability and body esteem, fatigue, disability, quality of life (QoL), anxiety and depression. RESULTS: Around 55% patients had a relationship; >79% and around 70% at least 1 gynaecological (especially dryness), and 1 muscle-skeletal symptom, respectively; around 60% sex disability for disease-related symptoms, mainly dryness (p=NS for all comparisons between pSS and SS). In both groups, disease changed sexual activity (around 50%), causing limitation (around 50%) and reduced frequency (>80%) in sexual intercourses; sex pleasure and satisfaction were around 30% and 25% (p=NS for pSS vs. SS). Around 55% patients discussed with partner disease-effects on relationship; despite in around 70% partner understood difficulties, in around 34% disease altered relationship (p=NS for pSS vs. SS). Around 16% patients were asked by HP if disease affected sexuality, around 30% never approached anyone to discuss about sex (p=NS for pSS vs. SS). Disability, QOL, mood, fatigue, similar in pSS versus SS (p=NS), were not affected by xerostomia and xeroftalmia, but by sex concerns and sex disability. CONCLUSIONS: Patients with pSS and SS present, often and at the same extent, gynaecological symptoms, leading to impaired sexual intercourse, affecting pleasure, satisfaction, sexual ability. | |
24651918 | Anti-CCP antibodies in Brazilian children and adults with juvenile idiopathic arthritis. | 2014 Jul | Patients with juvenile idiopathic arthritis (JIA) may need further care in the adult clinic as this disease frequently has continuous inflammatory activity during adult life. To identify which pediatric JIA patients will need continuing care into adulthood. We compared the clinical, serological, and demographic data of 45 JIA patients followed up by the pediatric clinic to those of 49 JIA patients in the adult rheumatology clinic. Patients in the adult clinic have older age at disease onset (p < 0.0001) and higher prevalence of positive anti-cyclic citrullinated peptide (CCP) (p = 0.05). No differences were observed in JIA form, presence of rheumatoid factor (RF), uveitis, and gender. Anti-CCP and older age at disease onset may identify pediatric JIA patients that will need further care in the adult clinic. | |
23812327 | The role of viruses in autoreactive B cell activation within tertiary lymphoid structures | 2013 Dec | TLS, characterized by the formation of ectopic B/T cell follicles with FDCs supporting an ectopic GC response, have been described in the target organs of several autoimmune diseases, including MS, RA, SS, and autoimmune thyroiditis. These structures represent functional niches, whereby autoreactive B cells undergo in situ affinity maturation and differentiation to autoantibody-producing cells, thus contributing to the progression and persistence of autoimmunity. Increasing evidence demonstrates that TLS can also develop in the context of cancer, as well as chronic infections. In this review, we collect recent evidences that highlights the relationship between persistent viral infection and the development of ectopic lymphoid structures in animal models and patients. Furthermore, we shall discuss the concept that whereas in physiological conditions, inducible TLS are critical for viral clearance and the establishment of protective immunity, but in the context of susceptible individuals, persistent viral infections may contribute, directly or indirectly, to the development of breach of tolerance against self-antigens and the development of autoimmunity through the formation of TLS. | |
23487338 | Crystal deposition disease and psoriatic arthritis. | 2013 Feb | To the practicing clinical radiologist, knowledge of the ultrasound appearances of crystal diseases is important. Assessment of bone or soft tissue changes related to rheumatoid arthritis is a rare clinical indication for ultrasound, whereas crystal diseases have a broad spectrum of presentations requiring clinical diagnostic imaging. Psoriatic arthritis is an entheseal disease with secondary joint involvement, where imaging findings include inflammatory enthesopathy with erosions as well as flexor tendon tenosynovitis. The ultrasound features of crystal deposition diseases and psoriatic arthritis in soft tissues and joints are relatively characteristic, and an awareness of these appearances is vital to the practicing musculoskeletal sonologist. | |
23463332 | Phellinus baumii ethyl acetate extract alleviated collagen type II induced arthritis in DB | 2013 Oct | Mushrooms have a long history of dietary benefits in Asia due to their health-promoting effects. Phellinus baumii, a wild mushroom, has been reported to have anti-platelet, anti-inflammatory, anti-obesity and free radical scavenging activities. However, its anti-rheumatoid arthritis (RA) property remains poorly understood. Hence, we investigated the protective effect of Phellinus baumii ethyl acetate extract (PBEAE) against bovine collagen type II induced arthritis (CIA) in DBA/1 mice. PBEAE (50 and 150 mg/kg) reduced the CIA score and leukocyte count in draining lymph nodes (DLNs) and inflamed joints. PBEAE also attenuated the expressions of CD3⺠(T cells), CD19⺠(B cells), CD4⺠(T-helper), CD8⺠(T-cytotoxic), MHC class II/CD11c⺠(antigen-presenting cells), double positives (B220âº/CD23⺠and CD3âº/CD69âº: early lymphocyte activation markers) and CD4âº/CD25⺠(activated T-helper) leukocyte subpopulations in DLNs. Likewise, CD3⺠and Gr-1âºCD11b⺠(neutrophil) counts in inflamed joints were also decreased. Furthermore, PBEAE reduced the serum levels of anti-collagen type immunoglobulin G, tumor necrosis factor-α and interleukin (IL)-1β and IL-6. Taken together, PBEAE impaired cellular recruitment to the inflamed joint and alleviated CIA, and thus could be considered as a potential agent against rheumatoid arthritis. | |
25313341 | Pneumocystis jirovecii Pneumonia in a Patient with Rheumatoid Arthritis Treated with Abata | 2014 | Rheumatoid arthritis (RA) is an autoimmune disease characterized by synovial membrane inflammation and joint cartilage destruction. Abatacept is a biologic agent that blocks the costimulation signals, preventing antigen presentation and proliferation of T lymphocytes. It is approved for the treatment of patients with RA. Pneumocystis jirovecii pneumonia (PJP) is an infectious disease complicating several immunosuppressive drugs. PJP associated with abatacept has not been reported yet in the medical literature. Various factors, such as the mechanism of action of abatacept, may contribute to predisposing to  Pneumocystis jirovecii infection. In this paper, we report a patient with RA who developed PJP under abatacept treatment. | |
24044168 | [Usefulness of thoracoscopy under local anesthesia in the diagnosis of tuberculous pleuris | 2013 Aug | We report the case of a 71-year-old man with rheumatoid arthritis. Infliximab administration was started as treatment for rheumatoid arthritis in January 2009. As he showed a positive result for the tuberculin test, he was treated with isoniazid for 9 months. He was subsequently referred to our department in October 2011 with a right-sided pleural effusion. When thoracoscopy was performed under local anesthesia, white and red protruding lesions of various sizes were observed in the pleural cavity. A biopsy revealed fibrous granulation tissue, and tissue culture and all sensitivity tests were positive for Mycobacterium tuberculosis. Therefore, thoracoscopy is useful for not only diagnosis but also determining whether resistant tuberculosis is present. | |
25268600 | Data on the safety of psoriasis therapies. | 2014 Jun | Safety remains paramount to the clinical utility of a therapy. Evaluation of safety is an ongoing process that does not end when a therapy becomes commercially available. This article reviews recent data pertaining to the safety profile of two therapeutic classes widely used in the treatment of psoriasis: inhibitors of tumor necrosis factor-α and agents that target interleukin-12/23. |
