| 22310967 | Etanercept is safely used for treating psoriatic arthritis in a patient complicated with t | 2012 Nov | Hereditary angioedema (HAE) is a life-threatening disorder caused by deficiency or dysfunction of the C1 inhibitor protein. Patients with HAE are restricted in various medical treatments, which can induce an HAE attack. We herein report the first case of psoriatic arthritis (PSA) with type 1 HAE successfully treated with 25 mg of etanercept without HAE attack. Etanercept may represent a useful choice for treating patients with HAE accompanied by intractable PSA and rheumatoid arthritis (RA). | |
| 22472935 | Adult-onset Still's disease misdiagnosed as pneumonia: two case reports. | 2011 Oct | Adult-onset Still disease (AOSD) is an uncommon inflammatory condition of unknown origin and pathogenesis. Pulmonary involvement is rare and includes pleuritis and transient radiological infiltrations. We report two cases of AOSD characterized by lung involvement at presentation. Both were misdiagnosed as pneumonia with para-pneumoÂnic effusion. We also discuss the difficulties in diagÂnosis of AOSD with pulmonary infiltration. | |
| 22447330 | Rheumatic disease presenting as septic arthritis: a report of 10 cases. | 2013 Aug | To determine the forms and characteristics of rheumatic diseases whose initial presentation mimics septic arthritis. Retrospective study of 398 patients hospitalized between 1979 and 2005 for arthritis diagnosed and treated as septic. In 10 cases, initial presentation of a rheumatic disease was highly suggestive of septic arthritis, and the patient was treated as such. Three had rheumatoid arthritis, 3 spondyloarthropathies, 2 unclassified rheumatic diseases, 1 Wegener granulomatosis and 1 cytosteatonecrosis. Mean time to diagnosis of rheumatic arthritis was 6 months. There were 7 males and 3 females aged from 15 to 77 years. Six had fever, and 3 had leucocytosis. Average ESR was 68 mm/1 h, and C-reactive protein was above 100 mg/l in 6 patients. Five patients had radiological signs suggestive of septic arthritis. Joint fluid count was above 100,000 WBCs/mm(3) in 2/5. Synovial biopsy suggested septic arthritis in 5 out of 6. These cases of pseudoseptic arthritis were indistinguishable from true septic arthritis. Follow-up is required in septic arthritis with negative culture findings to exclude rheumatic disease. | |
| 24179722 | Total wrist replacement: a retrospective comparative study. | 2012 Nov | Purpose Total wrist arthroplasty (TWA) is an evolving procedure for the treatment of arthritis of the wrist joint. The purpose of this study is to compare outcomes of three different total wrist implants. Methods A retrospective review of the Biaxial, Universal 2, and Re-Motion total wrist arthroplasties was performed. Patients were evaluated for clinical outcome, radiographic analysis, review of complications (incidence and type), and conversion to wrist fusion. Patient function measures included: the Mayo wrist score, the Patient Related Wrist Evaluation, and Disabilities of Arm, Shoulder, and Hand (DASH) score. Results Forty-six wrist implants were performed in 39 patients. There were 36 rheumatoid and 10 posttraumatic cases. The average follow-up was 6 years (3.5 to 15). The total wrist inserted included 16 resectional arthroplasties (Biaxial) and 30 resurfacing designs (Universal 2 and Re-Motion). Nine implant failures were noted. Causes for arthroplasty failure included distal component implant loosening and wrist instability. Salvage procedures included revision TWA or wrist fusion. In successful cases, flexion and extension motion averaged 30 and 38 degrees, respectively, and grip strength improved by 3 kg. Mayo wrist scores, in successful cases, increased from 40 (preoperative) to 76 (postoperative). The Mayo wrist scores for posttraumatic conditions averaged 87 points versus 71 points for rheumatoid arthritis. The average DASH score for the two resurfacing designs were 20 and 37, and 48 for the resectional arthroplasty design. Discussion Total wrist replacement maintains itself and provides good pain relief and functional motion in over 80% of all cases and in 97% of resurfacing implants. Better results were correlated with improved distal component fixation and minimal resection of the distal radius. Level of Evidence Level 3 Case Control. | |
| 22886618 | Elevated serum resistin in juvenile idiopathic arthritis: relation to categories and disea | 2013 Jan | BACKGROUND: Juvenile Idiopathic Arthritis (JIA) is one of the more common chronic diseases of childhood that often persists into adulthood and can result in significant long-term morbidity, including physical disability. The aim of the present study was to assess the serum level of resistin in JIA patients and compare its levels according to the categories, clinical manifestations and disease activity. METHODS: Sixty-eight JIA patients and 33 age and sex matched control children were included in the present study. All patients included in this study were subjected to full history taking, clinical examination. Juvenile arthritis disease activity score in 27 joints (JADAS-27) was calculated and Childhood Health Assessment Questionnaire (CHAQ) was used to measure the functional status. Serum resistin levels were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS: The mean serum resistin was significantly higher in the JIA patients (4.01 ± 2.46 ng/ml) compared to the control (2.08 ± 1.23 ng/ml) (p<0.001) especially those with systemic-onset. Its level was significantly higher in those receiving steroids and those with a positive antinuclear antibody. Resistin significantly correlated with the JADAS27 (r 0.26, p 0.035) and CHAQ (r 0.4, p 0.001). The JIA patients were 50 females and 18 males; however, the level of resistin was insignificantly different according to the gender although there was a tendency to be higher in females. CONCLUSION: Our results reinforce the proposition of an important role for resistin in JIA and may be considered an interesting biomarker for disease activity especially those with systemic onset. | |
| 23326962 | Systemic osteoporosis--major complication of psoriatic arthritis. | 2012 Apr | OBJECTIVES: Determination of bone mineral density in patients with psoriatic arthritis and its correlation with the development of the disease. METHODS: Three groups of patients were recruited: group 1--patients with psoriasis arthritis; group 2--patients with rheumatoid arthritis, group 3--control group. Group 1 was divided into: group 1A--patients with disease duration < 5 years and group 1B--patients with disease duration > 5 years. Bone mineral density was determined for total hip by dual X-ray absorptiometry (DXA). RESULTS: In the group 1A BMD values of total femur were between -1.32 and -1.68 DS; in the group 1B BMD values of total femur were between 1B -1.58 and - 1.77DS; in the group 2 BMD values of total femur were between -2.51 and -3.41 DS and in the control group BMD values of total femur were between 0.29 and 1.3 DS. In patients with psoriatic arthritis, the duration of arthritis was negatively correlated with BMD values of total femur. In conclusion, psoriatic patients with longer duration of disease may be at a risk for osteoporosis, which can require preventative treatment efforts. | |

| 23237458 | Anti-inflammatory activity of lycopene isolated from Chlorella marina on type II collagen | 2013 Apr | The role of commercially available lycopene (all-trans) from tomato in controlling arthritis has been reported. Even though many reports are available that the cis form of lycopene is more biologically active, no report seems to be available on lycopene (cis and trans) isolated from an easily available and culturable sources. In the present study, the anti-arthritic effect of lycopene (cis and trans) from the algae Chlorella marina (AL) has been compared with lycopene (all-trans) from tomato (TL) and indomethacin (Indo). Arthritis (CIA) was developed in male Sprague dawley rats by collagen and the following parameters were studied. The activities of inflammatory marker enzymes like cyclooxygenase (COX), lipoxygenase (LOX) and myeloperoxidase (MPO) were found to be decreased on treatment with AL when compared to TL and Indo. Changes in Erythrocyte sedimentation rate (ESR), white blood cell (WBC) count, red blood cells (RBC) count, hemoglobin (Hb), C-reactive protein (CRP), rheumatoid factor (RF), and ceruloplasmin levels observed in the blood of arthritic animals were brought back to normal by AL when compared to TL and Indo. Histopathology of paw and joint tissues showed marked reduction in edema on supplementation of AL. Thus these results indicate the potential beneficiary effect of algal lycopene on collagen induced arthritis in rats when compared to TL and even to the commonly used anti-inflammatory drug indomethacin. Therefore lycopene from C. marina would be recommended as a better natural source with increased activity and without side effects in the treatment of anti-inflammatory diseases. | |
| 22221757 | Anti-arthritis activity of roots of Hemidesmus indicus R.Br. (Anantmul) in rats. | 2012 Feb | OBJECTIVE: To investigate the protective effects of hydroalcoholic and its fractions from roots of Hemidesmus indicus on arthritis in in vitro models of rodents. METHODS: Preliminary phytochemical analysis and thin-layer chromoatography were performed to analyze constituents of hydroalcoholic extract and its three fraction namely ethyl acetate fraction, chloroform fraction and residual fraction of root of Hemidesmus indicus. Arthritis rats models were established by Complete Freund's Adjuvant. The parameters including paw edema, body weight, arthritic index, erythrocyte sedimentation rate, serum rheumatoid factor, serum C-reactive protein, serum nitrite level, and histopathology of synovial joints were observed. Methotrexate was taken as positive control. RESULTS: Rats treated with hydroalcoholic extract (450 mg/kg, p.o.), ethyl acetate (75 mg/kg, p.o.), chloroform (60 mg/kg, p.o) and residual fractions (270 mg/kg, p.o.), showed significant decrease in physical and biochemical parameters compared with arthritic model rats. Hydroalcoholic extract and its ethyl acetate fraction of Hemidesmus indicus showed significantly higher anti-arthritic activity than chloroform and residual fraction. Histopathological analysis demonstrated that both of hydroalcoholic extract and its ethyl acetate fraction had comparable anti-arthritic activity with methotrexates. CONCLUSIONS: The present study suggests that Hemidesmus indicus has protective activity against arthritis and the activity might be attributed to presence of terpenoid in hydroalcoholic extract, as well as in ethyl acetate fraction. | |

| 22784433 | The importance for daily occupations of perceiving good health: Perceptions among women wi | 2013 Mar | OBJECTIVE: The purpose was to describe and characterize what women with rheumatoid arthritis (RA) and juvenile idiopathic arthritis (JIA) perceive as important in considering the performance of daily occupations to perceive good health. METHODS: By using a phenomenographic research approach with semi-structured interviews with nine women between the ages of 42 and 65 the core category "Being able to be as active as possible in daily occupations" emerged. RESULTS: The women's repertoire of daily occupations had changed as the years had passed. To perceive good health the women expressed the importance of continuing to be active and to perform occupations as independently as possible despite their chronic rheumatic diseases. CONCLUSIONS: By adapting to their level of physical function and strength and by compensation with assistive devices, selecting adjusted environment, and by getting support from others, the women perceived good health. The results also suggested that training in different ways, medical treatment, and rheumatologic team care were related to increased performance of daily occupations and the perceptions of good health. | |
| 22245957 | Suppressive effect of an orally active MEK1/2 inhibitor in two different animal models for | 2012 May | OBJECTIVE AND DESIGN: To examine the effects of a mitogen-activated protein kinase/extracellular signal-regulated kinase kinase 1/2-inhibitor, JTP-74057, on inflammatory arthritis development, and compare its anti-arthritic effect with leflunomide. MATERIALS: Human, mouse, and rat peripheral blood mononuclear cells (PBMCs) were used. Lewis rats and DBA/1J mice were used for animal models. TREATMENT: JTP-74057 was tested between 0.1-100 nM in in-vitro studies. JTP-74057 (0.01-0.3 mg/kg) and leflunomide (2-10 mg/kg) were administered orally in vivo. METHODS: PBMCs were stimulated with lipopolysaccharide. Adjuvant-induced arthritis (AIA) and type II collagen-induced arthritis (CIA) was induced in Lewis rats or DBA1/J mice, respectively. RESULTS: JTP-74057 blocked tumor necrosis factor-α and interleukin-6 production from PBMCs. AIA and CIA development were suppressed almost completely by 0.1 mg/kg of JTP-74057 or 10 mg/kg of leflunomide. In the CIA, JTP-74057, but not leflunomide, suppressed collagen-reactive T-cell proliferation ex vivo, whereas leflunomide, but not JTP-74057, suppressed anti-collagen antibody production. CONCLUSIONS: JTP-74057 exerts potent anti-arthritic effects with a different profile from leflunomide, suggesting that JTP-74057 may be useful as a new therapeutic reagent in the treatment of rheumatoid arthritis. | |
| 23885318 | The role of sphingosine 1-phosphate in immunity and sepsis. | 2012 | Sphingosine 1-phosphate (S1P) is a lipid metabolite with intra- and extracellular signalling properties. It activates five G protein-coupled cell surface receptors designated S1P-receptors type 1-5 (S1P1-5) that transmit extracellular signals into cells, and it modulates intracellular signalling as a cofactor. The analysis of sphingosine kinases (SphK) type 1 and 2, the key enzymes for S1P production, in different infection models point to an important role for the activation of different immune cells like macrophages, mast cells, and dendritic cells. S1P additionally influences local and systemic lymphocyte circulation and positioning, the vascular tone, and blood pressure. Modulation of S1P-mediated signalling pathways therefore results either in local immune cell activation or systemic immune suppression, or both. Pharmacological approaches that modulate certain S1P-mediated signalling pathways while leaving others untouched appear to be promising new avenues for next generation pharmaceuticals. This review summarizes current strategies to modulate S1P signalling for immune intervention with the clear focus on the specificity of the different principles applied. Known local and systemic effects of S1P on immunity are discussed as potential pharmaceutical targets to combat immune and autoimmune diseases and sepsis. | |
| 23304154 | A Systematic Literature Review of the Association of Lipoprotein(a) and Autoimmune Disease | 2012 | Objective. To investigate the association of lipoprotein(a) and atherosclerosis-related autoimmune diseases, to provide information on possible pathophysiologic mechanisms, and to give recommendations for Lp(a) determination and therapeutic options. Methods. We performed a systematic review of English language citations referring to the keywords "Lp(a)" AND "autoimmune disease" AND "atherosclerosis," "Lp(a)" AND "immune system" OR "antiphospholipid (Hughes) syndrome (APS)" OR "rheumatoid arthritis" OR "Sjögren's syndrome" OR "systemic lupus erythematosus" OR "systemic sclerosis" OR "systemic vasculitis" published between 1991 and 2011 using Medline database. Results. 22 out of 65 found articles were identified as relevant. Lp(a) association was highest in rheumatoid arthritis (RA), followed by systemic lupus erythematosus (SLE), moderate in APS and lowest in systemic sclerosis (SSc). There was no association found between Lp(a) and systemic vasculitis or Sjögren's syndrome. Conclusion. Immune reactions are highly relevant in the pathophysiology of atherosclerosis, and patients with specific autoimmune diseases are at high risk for CVD. Elevated Lp(a) is an important risk factor for premature atherosclerosis and high Lp(a) levels are also associated with autoimmune diseases. Anti-Lp(a)-antibodies might be a possible explanation. Therapeutic approaches thus far include niacin, Lp(a)-apheresis, farnesoid x-receptor-agonists, and CETP-inhibitors being currently under investigation. | |
| 23118783 | Understanding the molecular mechanism of interventions in treating rheumatoid arthritis pa | 2012 | Better effectiveness would be achieved when interventions are used in treating patients with a specific traditional Chinese medicine (TCM) pattern. In this paper, the effectiveness in treating rheumatoid arthritis (RA) patients in a randomized clinical trial as reanalyzed after the patients were classified into different TCM patterns and the underlying mechanism of how the TCM pattern influences the clinical effectiveness of interventions (TCM and biomedicine therapy) was explored. The pharmacological networks of interventions were builtup with protein and protein interaction analyses based on all the related targeted proteins obtained from PubChem. The underlying mechanism was explored by merging the pharmacological networks with the molecular networks of TCM cold and hot patterns in RA. The results show that the TCM therapy is better in treating the RA patients with TCM hot pattern, and the biomedical therapy is better in the RA patients with cold pattern. The pharmacological network of TCM intervention is merged well with the molecular network of TCM hot pattern, and the pharmacological network of biomedical therapy is merged well with the network of cold pattern. The finding indicates that molecular network analysis could give insight into the full understanding of the underlying mechanism of how TCM pattern impacts the efficacy. | |
| 22978259 | Quantification of citrullination by means of skewed isotope distribution pattern. | 2012 Nov 2 | Citrullination is a post-translational modification of arginine, resulting in a loss of positive charge and a 1 Da mass increase. Research on citrullinated proteins is crucial in rheumatoid arthritis, an autoimmune disease characterized by the presence of antibodies against citrullinated proteins. However, little is known about the location or quantity of deiminated arginine residues in these proteins. Since citrullination gives rise to a mass gain of only 1 Da, the isotope pattern of the citrullinated and the noncitrullinated version of a peptide will overlap. However, the difference between the theoretical, or noncitrullinated, and the measured isotope pattern can be used to quantify the amount of citrullination. We developed a method to quantify citrullinated peptides by means of their skewed isotopic distribution pattern. The method was first optimized with synthetic peptides, after both direct infusion and RP-HPLC separation on an ESi-QqTOF mass spectrometer. Additionally, we analyzed synovial fluid samples from rheumatoid arthritis patients and were able to quantify citrullinated peptides originating from citrullinated fibrinogen, a well-known antigen. | |
| 23209474 | Translating Policy into Practice for Community-Based Management of Rheumatoid Arthritis: T | 2012 | Introduction. Contemporary health policy promotes delivery of community-based health services to people with musculoskeletal conditions, including rheumatoid arthritis (RA). This emphasis requires a skilled workforce to deliver safe, effective care. We aimed to explore physiotherapy workforce readiness to co-manage consumers with RA by determining the RA-specific professional development (PD) needs in relation to work and educational characteristics of physiotherapists in Western Australia (WA). Methods. An e-survey was sent to physiotherapists regarding their confidence in co-managing people with RA and their PD needs. Data including years of clinical experience, current RA clinical caseload, professional qualifications, and primary clinical area of practice were collected. Results. 273 physiotherapists completed the survey. Overall confidence in managing people with RA was low (22.7-58.2%) and need for PD was high (45.1-95.2%). Physiotherapists with greater years of clinical experience, a caseload of consumers with RA, postgraduate qualifications in musculoskeletal physiotherapy, or who worked in the musculoskeletal area were more confident in managing people with RA and less likely to need PD. Online and face-to-face formats were preferred modes of PD delivery. Discussion. To enable community-based RA service delivery to be effectively established, subgroups within the current physiotherapy workforce require upskilling in the evidence-based management of consumers with RA. |
