19252249 [Prevention of joint destruction by osteoclast-targeting therapy in search of new tools, s 2009 Mar We should consider not only controlling disease activity using DMARDs and biologics as a matter of course, but also preventing against joint destruction, in the treatment for rheumatoid arthritis. Although we can indirectly regulate bone erosion via controlling disease activity, the osteoclast-targeting therapy might be more effective to stop joint destruction. We are waiting for new drugs directly targeting osteoclasts, such as OPG which is the natural inhibitor of RANKL, or cathepsin K inhibitor which reduces degeneration of bone matrix.
20051167 [The Dutch College of General Practitioners' practice guideline on arthritis]. 2009 The Dutch College of General Practitioners' new practice guideline on arthritis combines arthritis and gout. One of the important improvements in this guideline is that it recommends that patients be referred to the rheumatologist as soon as 4 weeks after being seen, or earlier, if rheumatoid arthritis is likely or suspected. Obviously, these early referrals are related to the large increase in effective treatment options in rheumatoid arthritis, particularly after early treatment (window of opportunity). The new guideline relating to gout advocates the use of oral prednisone as the second choice in patients without an adequate treatment response or who do not tolerate NSAIDs: colchicine and intra-articular injections may be attractive alternatives.
21120560 Decreased need of large joint replacement in patients with rheumatoid arthritis in a speci 2011 Apr Disease-modifying antirheumatic biological and non-biological therapies are associated with reduced disease progression and joint destruction. Suggestions have been made that total knee and hip joint arthroplasty indications are decreasing as a beneficial effect of the new forms of therapy for rheumatoid arthritis. We present findings of our institution on the incidence of joint arthroplasty in the past few years in patients with rheumatoid arthritis and the increase in the numbers of procedures not associated with inflammatory arthritis.
20427826 Discrepancy between anatomical axis and stem position of various femoral components in Jap 2010 Apr PURPOSE: To evaluate the discrepancy between the anatomical axis of the distal femur of Japanese patients and the stem position of 5 types of femoral components. METHODS: Lateral radiographs of 12 men and 88 women aged 31 to 83 (mean, 59) years with rheumatoid arthritis were evaluated. The discrepancy between the anatomical axis of the distal femur and the stem position of 5 types of femoral components (Nexgen LCCK, Press-Fit Condylar, Scorpio, Total Stabilizer, and Rotating Hinge) was determined by superimposing the template of each model over each lateral radiograph. RESULTS: The anatomical axis varied widely among our patients, as did the stem position of the 5 femoral components. Stems of all 5 femoral components tended to be more posterior than the anatomical axis. The discrepancy was smallest in the Nexgen LCCK, followed by the Press-Fit Condylar components. It was >3 mm in the other 3 models. In 35% of the patients, none of the prosthesis could be placed in an appropriate position. Smaller-size prostheses appear necessary for the Japanese. CONCLUSION: The stem position should be an important factor guiding selection of the appropriate model. The currently available femoral components may not be appropriate for the Japanese. Prostheses with appropriately positioned stems for Japanese patients with rheumatoid arthritis should be developed.
20972869 Isolated intra-articular pseudorheumatoid nodule of the knee. 2011 Apr The authors describe a case of an isolated intra-articular pseudorheumatoid nodule of the knee in an 18-year-old male patient without a diagnosis of rheumatoid arthritis. The patient initially presented with a 3 year history of anterior knee pain and was found to have a 2.8 × 2.1 cm lobulated soft-tissue mass. Histologic findings showed fibrinoid necrosis and chronic inflammatory changes that were consistent with those of a pseudorheumatoid or rheumatoid nodule, and surgical excision of the nodule was curative. A review of the literature revealed no prior cases of an intra-articular pseudorheumatoid nodule or rheumatoid nodule in a patient without clinical or serologic evidence of rheumatoid arthritis.

20617752 [Biological therapy in rheumatoid arthritis based on ten years of registry surveillance in 2010 Biological drugs are used in the treatment of active inflammatory athritides refractory to conventional treatment. Data from the Finnish registry of biological treatment (ROB-FIN) indicates that the effectiveness of the biologicals in clinical practice corresponds to or even excels that of randomized controlled clinical trials, and seems to endure in patients continuing treatment. About one-fifth of rheumatoid arthritis patients discontinue treatment due to lack of effectiveness, and one-tenth due to adverse events. Serious adverse events were seen in 2.5% of all patients. In the future electronic follow-up, pharmacogenetics, and biomarker research may help to better optimize treatment individually.

20387530 [A case of miliary tuberculosis showing acute respiratory distress syndrome in rheumatoid 2010 Mar A 62-year-old man, treated with corticosteroids and immunosuppressants for rheumatoid arthritis, visited hospital with high fever and dyspnea on exertion. A CT scan of the chest demonstrated bilateral diffuse ground glass opacities. On the basis of the findings of the CT scan, he was initially given a diagnosis of interstitial pneumonia. He was then referred to our hospital and admitted to the intensive care unit (ICU), where because of progressive respiratory failure, he was put on mechanical ventilation. A bronchoscopy specimen after intubation turned out to be positive for acid-fast bacilli, which were confirmed to be mycobacterium tuberculosis by a polymerase chain reaction test. He was given a diagnosis of miliary tuberculosis complicated with acute respiratory distress syndrome (ARDS). He died of respiratory failure despite treatment with antituberculosis drugs. The autopsy revealed necrotizing epithelioid granulomas in both lungs, mediastinal lymph nodes, the liver, both kidneys, vertebrae and other organs. Diffuse alveolar damage was also found in both lungs. It is often difficult to detect disseminated nodules in the miliary tuberculosis with ARDS. Miliary tuberculosis should be suspected in patients in an immunosuppressant state with rheumatoid arthritis, and who have respiratory symptoms or fever of unknown origin.
19770836 [Indicators of the spontaneous B-lymphocytes proliferation in diagnostics of neurological 2009 An aim of the paper was to study indicators of the spontaneous B-lymphocytes proliferation activity (SBLPA) in patients with rheumatoid arthritis (RA) and lesions of the nervous system. Fifty-eight patients with neurological symptoms of RA were studied. A comparison group included 42 patients with RA without lesions of the nervous system. A control group consisted of 30 healthy people. The investigation of SBLP was conducted using a method of R. Rigler in the modification of E.V. Benenson et al. Significant between-group differences allow to conclude that indicators of SBLP can be used for diagnostics of nervous system lesions in RA.
19250230 MRI for assessing erosion and joint space narrowing in inflammatory arthropathies. 2009 Feb The superior soft tissue contrast and multiplanar capability of magnetic resonance imaging has contributed to earlier diagnosis and implementation of effective treatment for a variety of arthropathies. Owing to overlapping clinical signs and symptoms, MRI plays a role in delineating the features and stages of these conditions. With the advent of disease-modifying therapies, it is important to diagnose inflammatory arthropathy as early as possible. In this chapter, we discuss the pathophysiology of bone erosion and joint space narrowing, as well as the role of MRI in the imaging of the seropositive and seronegative inflammatory arthropathies.
19182757 Proliferative glomerulonephritis with acute renal failure-a rare manifestation in seronega 2009 Jan A 55 years old lady with advanced rheumatoid arthritis (RA) presented with severe acute renal failure with significant proteinuria preceded by fever for 14 days. She had no history of taking drugs usually responsible for glomerulonephritis, neither had she any clinico-biochemical evidence of peri-infectious glomerulonephritis. Acute interstitial nephritis (AIN) was excluded by absence of eosinophilia and eosinophils in urine. Renal biopsy reveled absence of amyloidosis and showed Focal segmental proliferative glomerulonephritis (FSGN). Patient was successfully managed with methyl-prednisolone followed by steroid and immunosuppressive and patient came over renal failure. So FSGN should be considered as one of the causes of acute renal failure in a patient with seronegative RA which may respond to immune-therapy like rapidly progressive glomerulonephritis.
20225458 Computational assessment of press-fit acetabular implant fixation: the effect of implant d 2010 Patients suffering from rheumatoid arthritis typically have a poor subchondral bone quality, endangering implant fixation. Using finite element analysis (FEA) an investigation was made to find whether a press-fit acetabular implant with a polar clearance would reduce interfacial micromotions and improve fixation compared with a standard hemispherical design. In addition, the effects of interference fit, friction, and implant material were analysed. Cups were introduced into an FEA model of a human pelvis with simulated subchondral bone plasticity. The models were loaded with a loading configuration simulating two cycles of normal walking, during which contact stresses and interfacial micromotions were monitored. Subsequently, a lever-out simulation was performed to assess the fixation strength of the various cases. A flattened cup with good bone quality produced the lowest interfacial micromotions. Poor bone decreased the fixation strength regardless of the geometry of the cup. Increasing the interference fit of the flattened cup compensated for the loss of fixation strength caused by poor bone quality. In conclusion, a flattened cup did not significantly improve implant fixation over a hemispherical cup in the case of poor bone quality. However, implant fixation can be optimized by increasing interference fit and avoiding inferior frictional properties and low-stiffness implants.
19722009 Future perspective for diagnosis in autoimmune diseases. 2009 Sep Human beings have taken successive approaches for the understanding and management of diseases. Initially brewed in supernatural concepts and mystical procedures, a vigorous scientific approach has emerged on the grounds of fundamental disciplines such as anatomy, microbiology, biochemistry, physiology, immunology, pathology, and pharmacology. The resulting integrated knowledge contributed to the current classification of diseases and the way Medicine is carried out today. Despite considerable progress, this approach is rather insufficient when it comes to systemic inflammatory conditions, such as systemic lupus erythematosus, that covers clinical conditions ranging from mild pauci-symptomatic diseases to rapidly fatal conditions. The treatment for such conditions is often insufficient and novel approaches are needed for further progress in these areas of Medicine. A recent breakthrough has been achieved with respect to chronic auto-inflammatory syndromes, in which molecular dissection of underlying gene defects has provided directions for target-oriented therapy. Such approach may be amenable to application in systemic auto-immune diseases with the comprehension that such conditions may be the consequence of interaction of specific environmental stimuli and an array of several and interconnected gene polymorphisms. On the bulk of this transformation, the application of principles of pharmacogenetics may lead the way towards a progressively stronger personalized Medicine.
20862480 [Inflammation-related cardiovascular morbidity : Pathophysiology and therapy]. 2010 Oct Rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) are associated with increased mortality, largely as a consequence of cardiovascular (CV) disease. Studies found relative risk ratios of 2 for myocardial infarction in RA and up to 7 for myocardial infarction in SLE patients.Beyond the traditional CV risk factors, chronic systemic inflammation has been shown to be a crucial factor in atherosclerosis development and progression from endothelial dysfunction to plaque rupture and thrombosis. Numerous studies have shown that atherosclerosis is not a passive process characterized by accumulation of lipids in the vessel walls, but rather represents active inflammation of the vasculature. Inflammatory cells such as macrophages, monocytes and T cells play an important role in the development of both RA and atherosclerosis.According to the recently published EULAR recommendations for CV risk screening and management in patients with inflammatory arthritis, annual CV risk assessment is recommended for all patients with RA. Any CV risk factors identified should be optimally managed. In addition to appropriate CV risk management, aggressive suppression of the inflammatory process is recommended to further lower CV risk.

19711150 Radiographic repair in three Japanese patients with rheumatoid arthritis treated with buci 2009 Bucillamine (Bc) is a cysteine derivative with two SH groups, and a homolog of D-penicillamine, a disease-modifying antirheumatic drug (DMARD) widely used in Japan. However, it remains unclear whether Bc repairs bone erosion in patients with RA. Here, we treated three RA patients with Bc who subsequently showed radiographic repair of erosions and cysts.
19790115 Association of functional outcome with both personal- and area-level socioeconomic inequal 2009 Oct 15 OBJECTIVE: To describe the relationship between baseline area- and person-level social inequalities and functional disability at 3 years in patients with early inflammatory polyarthritis (IP). METHODS: A total of 1,393 patients with new-onset IP were recruited and allocated an Index of Multiple Deprivation (IMD) 2004 score based on their area of residence, and a social class based on baseline self-reported occupation. Differences in the Health Assessment Questionnaire (HAQ) score at baseline and 3 years by IMD or social class were tested. The mean 3-year change in HAQ score was compared by IMD and social class, and interactions between these measures examined. RESULTS: Patients from more deprived areas had poorer 3-year HAQ outcome than those from less deprived areas (P = 0.019, adjusted for baseline HAQ score, age, sex, and symptom duration). The mean difference in HAQ change was most notable between the most deprived (IMD4) and least deprived areas (IMD1) (0.22; 95% confidence interval [95% CI] 0.11, 0.34). There was also a significant difference in HAQ score change between patients of the highest (SCI and II) and lowest social class (SCIV and V) (0.11; 95% CI 0.02, 0.20). For the mean (95% CI) 3-year change in HAQ score, a significant interaction exists between IMD score and social class and their association with HAQ scores (P = 0.001) to modify outcome: IMD1/SC I and II -0.23 (95% CI -0.40, -0.06) versus IMD 4/SC IV and V 0.15 (95% CI -0.05, 0.34). CONCLUSION: Person- and area-level inequalities combine to modify outcome for rheumatoid arthritis. A person's social circumstance and residential environment have independent effects on outcome and are not just alternative measures of the same exposure.
19387648 In-office magnetic resonance imaging to monitor responses to therapy in rheumatoid arthrit 2009 Dec Low-field extremity magnetic resonance imaging (MRI) has been developed as an alternative method for detecting inflammatory changes and structural damage associated with rheumatoid arthritis (RA). Studies have shown that extremity MRI is able to predict future joint damage in patients with early RA and is more sensitive than conventional radiography at detecting joint erosions. This report uses four different cases to illustrate how extremity MRI can be used to monitor disease activity and inform treatment decisions during the management of RA in the routine clinical practice setting.
