16724370 | Therapies for psoriatic enthesopathy. A systematic review. | 2006 Jul | Enthesitis is defined as inflammation at sites of tendon, ligament, joint capsule, or fascia insertion sites to bone, and is a hallmark feature of psoriatic arthritis. Several outcome measures have been developed to assess enthesitis, but none have been validated in psoriatic arthritis. In this evidence-based review, we assess the limited data on treatments for enthesitis and make recommendations for further studies in psoriatic enthesitis. | |
16234990 | Volume of a wash and the other conditions for maximum therapeutic effect of arthroscopic l | 2006 Feb | The objective of this study was to determine the appropriate volume of saline to obtain a beneficial effect of arthroscopic lavage and the prognostic factors related to the clinical effect in a refractory rheumatoid knee. Arthroscopic lavage or arthrocentesis was performed in a random manner in 142 patients with relapsing rheumatoid arthritis. All patients were followed up for 24 months. Intra-articular lavage with 5 l (p < 0.01) or 3 l (p < 0.05) of saline gave better clinical results than did arthrocentesis. There was no significant difference between the cumulative incidence of recurrence of knee synovitis in patients who underwent arthrocentesis and that in patients who underwent lavage with 1 l of saline. Cox regression analysis showed that patients with knee arthritis of more than 6 months in duration and with Larsen grade II or less were more responsive to lavage with 5 or 3 l of saline. The duration of the effect of lavage with 3 l of saline was increased 2.9-fold (p = 0.04) by injection of both steroids and high molecular weight hyaluronan. No bleeding or infectious complications occurred after those procedures. Arthroscopic lavage with 5 l of saline is safe and has good therapeutic effects for rheumatoid knees with mild destruction in which arthritis has persisted for more than 6 months. Lavage with 3 l of saline is recommended when intra-articular injection of corticosteroid and high molecular weight hyaluronan is performed after lavage. | |
17405310 | Patterns of peripheral cellular immune disorders in severe rheumatoid arthritis. | 2005 Jan | The study is focused on the correlated peripheral cellular immune disorders registered in a group of 23 patients with severe, progressive rheumatoid arthritis, on methotrexate therapy. We investigated a panel of peripheral immune parameters: leukocyte counts, the proportions of lymphocyte populations (T, Thelper, Tcytotoxic/suppressor, B lymphocytes and NK cells) and the polyclonal activation of lymphocytes. Results show that leukocytosis is due to simultaneously elevated values of monocytes, granulocytes and, to a lesser extent, lymphocytes. The registered high values of the Th to Tc/s ratio are mainly attributed to the abnormal low proportions of the Tc/s subpopulation. Inverse correlations were emphasized between B, Tc/s lymphocytes and NK cells or granulocytes. The unbalance of the lymphocyte to monocyte ratio or of the Th to Tc/s ratio does not impair the polyclonal activation of lymphocytes. In conclusion, we have characterized different patterns of correlated cellular peripheral immune disorders in rheumatoid arthritis, associated to pathological processes in conjunction with the immunsuppressive and anti-inflammatory action of methotrexate that might be relevant for further investigation of disease and further therapy outcome. We emphasize the special relation between the adaptive and innate immune system at the level of cell counts and proportions. The correlations between the peripheral abnormalities in the rheumatoid arthritis group are better highlighted by analyzing subgroups of patients characterized by particular values of the investigated parameters. | |
15588969 | The different stages of synovitis: acute vs chronic, early vs late and non-erosive vs eros | 2005 Feb | Rheumatoid arthritis is a systemic inflammatory disease that, by definition, can affect all parts of the human body, including severe complications such as uveitis/episcleritis and vasculitis of the heart, lungs, kidneys and the central and peripheral nervous systems. Its primary and by far the most common manifestations, however, affect the joints and are characterised by inflammatory reactions and activation of the synovial lining tissue and associated structures, the latter resulting in tenovaginitis and rheumatoid nodules. As all pathophysiological mechanisms are based on pathways that are inherent in the different components of a joint, it is necessary to examine the unique features of normal synovium prior to analysing disease-specific pathways. This chapter will therefore describe the physiological structure of the synovium and the inflammatory pathology of rheumatoid synovitis in early and chronic stages of the disease. | |
15909175 | [The enthesis. Physiological morphology, molecular composition and pathoanatomical alterat | 2005 Jun | The composition of the extracellular matrix in tendons and ligaments is directly related to the mechanical environment. Local compression triggers functional adaptation that leads to cartilage-specific transformation of the tissue. The molecular composition of the extracellular matrix at the enthesis is related to the amount of stress and to the geometry of the insertion. Comparison of physiologically and non-physiologically loaded entheses shows that only certain molecules occur under relatively high amounts of local compressive stress. The occurrence of certain cartilage specific molecules is clinically relevant, because some of these molecules have been identified as autoantigens during the autoimmune response in patients with rheumatoid arthritis. These molecules constitute potential targets for the manifestation of rheumatoid arthritis at fibrocartilaginous entheses. | |
16697258 | B cell depletion therapy in systemic rheumatic diseases: different strokes for different f | 2006 Oct | Autoantibodies have, until recently, been the overriding focus of investigators of autoantibody-associated diseases. Increasing attention is now being paid to B cells, which not only are the producers of autoantibodies but also contribute to autoimmune disease via autoantibody-independent mechanisms. Therapeutic measures that target B cells for depletion are gaining in popularity. In this review, we will focus on two distinct approaches of depleting B cells; one employing a direct-kill approach by engagement of B cell surface CD20 with an anti-CD20 monoclonal antibody (rituximab), and the other employing an indirect starvation approach by neutralization of B lymphocyte stimulator (BLyS), a potent B cell survival factor. Among the systemic immune-based rheumatic disorders, we will focus on rheumatoid arthritis and systemic lupus erythematosus, two disorders for which therapeutic B cell targeting is being intensely investigated. | |
16583483 | Twenty-year remission of rheumatoid arthritis in 2 patients after allogeneic bone marrow t | 2006 Apr | We describe 21 and 19 year followup of 2 patients with severe rheumatoid arthritis (RA) who in 1984 and 1986 underwent allogeneic bone marrow transplantation (BMT) after full myeloablative conditioning, for therapy-induced aplastic anemia. Regarding the arthritis, both patients are well, taking no medications, and free of signs or symptoms of active RA. One patient is in excellent health overall, while the other has coronary artery disease and chronic obstructive pulmonary disease attributable to smoking. We suggest that allogeneic BMT may be a curative treatment for severe RA. | |
17043771 | [Differential diagnosis of rheumatoid granuloma]. | 2006 Nov | Rheumatoid granuloma (RG) is histomorphologically defined as a subcutaneous palisading granuloma with central fibrinoid necrosis. Clinically, it presents as a nodule typically localized at pressure points near the joints. From the rheumatic pathological point of view, the main diagnostic challenge is the differentiation of RG from granuloma anulare, especially if clinical information on the site of removal, known diseases, duration of illness, medication and existing American College of Rheumatology (ACR) criteria are missing. Other granulomatous lesions, such as mycobacterial infections, foreign body granulomas, necrobiosis lipoidica or sarcoidosis, can be differentiated from RG by histopathological criteria or by additional examinations such as pathogen specification or PCR. An immunohistochemical marker for the differential diagnosis of granulomas is not yet available. Diagnosis is based on conventional H-E staining, alcian blue-PAS staining, polarizing analysis or PCR. In the following article, the most important granulomatous entities in the differential diagnosis of RG are introduced and the main diagnostic characteristics are discussed. | |

16622906 | Which variables best predict change in rheumatoid arthritis therapy in daily clinical prac | 2006 Jul | OBJECTIVE: To determine in clinical practice which clinical status variables for rheumatoid arthritis (RA) are most closely associated with a change in disease modifying antirheumatic drug (DMARD) therapy. METHODS: A prospective monocenter study was conducted in 204 consecutive patients with RA. Rheumatologists recorded patient characteristics, treatments, and disease activity data [tender and swollen joint count (28), morning stiffness, visual analog scale (VAS) for pain (0-100 mm), patient global assessment and physician global assessment, Westergren erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP)]. The rheumatologists decided whether or not to initiate or change treatment but were not informed that their decisions were part of the investigation. Logistic regression analysis was performed to evaluate which study variables best predict change in therapy. ROC analysis was used to obtain the cutoff value of the different composite indices (DAS28(ESR), DAS28(CRP), SDAI) for treatment change, as well as sensitivity and specificity. RESULTS: The variables that were predictive for a change in treatment were (in descending order): swollen joint count, morning stiffness, CRP, tender joint count, and patient global assessment. Composite index values associated with a decision to modify DMARD therapy were: DAS28(ESR) 4.2 (sensitivity 87%, specificity 70%); DAS28(CRP) 3.6 (sensitivity 86%, specificity 78%); and SDAI 15 (sensitivity 90%, specificity 86%). The discriminative ability of SDAI was better than that of DAS28(CRP) or DAS28(ESR). CONCLUSION: In our study, swollen joint count was the variable with the greatest weight, which explains the observed better performance of SDAI. | |
16425069 | [Successful therapy of a rheumatoid leg ulcer with intravenous immunoglobulins]. | 2006 Dec | Rheumatoid arthritis (RA) is a chronic, systemic inflammatory disease. Leg ulcers in rheumatoid arthritis may be caused by vasculitis and are an interdisciplinary therapeutic challenge. A 69 year old women with rheumatoid arthritis and many other medical problems presented with widespread vasculitis-induced therapy-resistant ulceration on her right lower leg. Since previous therapeutic efforts had a negative effect on wound healing, we administered intravenous immunoglobulins which led to complete healing of the ulcer was achieved. Both the serological and rheumatologic features of her rheumatoid arthritis also improved. Intravenous immunoglobulins represented an effective therapeutic option with fewer side effects in the therapy of vasculitis-induced leg ulceration in this patient with rheumatoid arthritis. | |
17149054 | Polyarthritis flare complicating rheumatoid arthritis infliximab therapy: a paradoxic adve | 2006 Dec | BACKGROUND: The treatment of rheumatoid arthritis (RA) has changed dramatically over the past decade with the introduction of antitumor necrosis factor (anti-TNF) agents. Although subsets of patients may have only partial or no response, there is no report yet on possible worsening of RA with this therapy. OBJECTIVE: The objective of this study was to determine whether infliximab may paradoxically exacerbate RA. METHODS: One hundred seven patients with RA refractory to 3 disease-modifying antirheumatic drugs were treated with 3 mg/kg infliximab and methotrexate for at least 6 months. RESULTS: In 3 patients, there was an exacerbation of RA associated with the use of infliximab. The flare occurred during the first 6 to 12 months of treatment with polyarthritis, fever, and elevated acute phase reactants. Increase of infliximab dose resulted in further deterioration. CONCLUSION: We describe a paradoxic reaction, an exacerbation of RA, with infliximab. The mechanism of this side effect is unclear but may be related to altered immunity induced by the inhibition of TNF activity in predisposed patients. | |
15885453 | Scintigraphic imaging of radiolabelled drug delivery systems in rabbits with arthritis. | 2005 May 30 | This paper describes a novel approach for designing drug delivery systems for intra-articular (i.a.) treatment of rheumatoid arthritis. Retention of these systems was evaluated by radiolabeling with Tc-99m and gamma scintigraphy in arthritic rabbits. Liposome, niosome, lipogelosome and niogelosome formulations of Diclofenac Sodium (DFNa) have been prepared and drug release properties and in vitro characterisation studies have been carried out. According to characterisation results L1 (DMPC: CHOL: DCP (7:1:2)), L1J1 (DMPC: CHOL: DCP (7:1:2) in C-940 1:1 (w/w)), N (SUR I: CHOL: DCP (7:1:2)) and NJ1 (SUR I: CHOL: DCP (7:1:2) in C-940 1:1 (w/w)) formulations were chosen for the further studies. Retention time of these formulations was evaluated by gamma scintigraphic imaging studies. Rabbits with antigen-induced arthritis were injected intra-articularly with Tc-99m labelled drug delivery systems. Serial scintigraphic images were obtained to investigate the retentions of labelled drug delivery systems in the arthritic joints and choose a suitable formulation for the treatment protocol of arthritis. At the end of the scintigraphic imaging studies it was observed that radiolabelled lipogelosome formulation containing DFNa (L1J1) retained much longer in the experimentally arthritic knee joints of the rabbits. This formulation was used for the treatment protocol of arthritis. Mono articular arthritis was induced in the knee joints of rabbits and it was monitored at regular time intervals by measuring changes in knee joint diameter. Also macroscopic and histopathologic evaluations were performed for further evaluation of arthritis. Great retention of DFNa in the arthritic joint might reduce potential adverse systemic effects of the drug because of local administration into the diseased area. It appeared to be a promising drug delivery system for intra-articular drug delivery. | |
15744657 | [Aims of hand therapy in treatment of rheumatoid hand]. | 2005 Feb | When dealing with rheumatoid arthritis, the main issues of hand therapy are the treatment of hand and finger joints. We emphasize mobilisation of joints, muscle strengthening, correcting deformities by low temperature splints and joint protection. Further tasks of occupational therapy are: Informing patients about adaptive devices and training their use as well as educational programs for patients with reduced mobility of the upper limb. The most common surgery on the rheumatoid hand, that need postoperative treatment by a hand therapist are complete and limited arthrodesis of the wrist, surgical reconstruction of tendons, arthroplasty and arthrodeses of and for finger joints, and so on. At the Nordwestdeutsches Rheumazentrum St. Josef-Stift Sendenhorst we have designed a standard postoperative management for treating arthroplasty with a "Silikonspacer" in the metacarpophalangeal joints. | |
17621799 | [Treatment of rheumatoid arthritis (RA) with anticytokines]. | 2006 Oct 19 | In the hands of an experienced rheumatologist and in adherence to the contraindications named in the article, anticytokines such asTNF-alpha blockers or interleukin-1 antagonists are regarded as relatively reliable, are well tolerated and in many cases, are very effective. Especially when used in combination with methotrexate, they demonstratively lower the disease activity score and significantly slow the radiographic progression.Thus, anticytokines are currently the most effective therapy for RA. An additional advantage compared to conventional DMARD is the rapid onset of action (usually within two to four weeks).TNF-alpha blockers are also presently employed in numerous other chronic inflammatory diseases. The efficacy of anticytokines in psoriasis and psoriatic arthritis, ankylosing spondylitis, juvenile arthritis and Crohn's disease has been proven. | |
16362449 | Syringomyelia, neuropathic arthropathy and rheumatoid arthritis as diagnostic dilemmas in | 2007 Jan | Two patients with neuropathic arthropathy (NA) of hands and wrists due to cervical syringomyelia are described. Articular deformities resembling rheumatoid arthritis (RA) were present in both cases. RA was misdiagnosed in the first case, leading to incorrect treatment with iatrogenic consequences, and there was real coexistence of RA and NA in the second one. Physicians must be aware of this rare condition in the differential diagnosis of wrist and hand deformities. | |
17021669 | Influence of intraarticular corticosteroid administration on serum cytokines in rheumatoid | 2007 May | Though the efficacy of intraarticular (IA) corticosteroid administration in the therapeutic management of rheumatoid arthritis (RA) has been well documented, its immunomodulatory effects have not been defined. Categorization of these effects is important to develop safe derivative therapeutic strategies with a more targeted mechanism of action as they relate to the pathophysiology of RA. We describe here a broad spectrum immune response to inflammation as evidenced by rapid transient systemic inhibitory effects on key inflammatory regulators induced by the effects of IA administration of triamcinolone acetonide in a case of active RA who failed to respond to methotrexate. | |
17139664 | Patients' preferences for decision making and the feeling of being understood in the medic | 2006 Dec 15 | OBJECTIVE: To examine how patients' preferences for decision making in the medical encounter affect the association between their participation style and the feeling of being understood by the physician. METHODS: The study group comprised 115 patients with rheumatoid arthritis who were under continuous care by 8 rheumatologists at a university-affiliated rheumatology clinic in Tokyo, Japan. A questionnaire was distributed just after each encounter, in which patients' self-reported participation in communication during the visit, preference for decision making, and the feeling of being understood were measured. The feeling of being understood was regressed on the participation style and preference for decision making after controlling for demographic and functional variables. RESULTS: Patient participation in visit communication was positively associated with the feeling of being understood. This relationship was moderated by patients' preference for decision making. Patients with higher preference for decision making were more likely to feel understood when they more actively participated in visit communication, whereas this relationship was weaker among those with lower preference for decision making. CONCLUSION: Inviting patients to participate in visit communication may not always enhance the feeling of being understood by the physician when patients have less preference for autonomous decision making in the relationship with the physician. Exploring patients' preferences in the relationship would help physicians understand what the patient expects from visit communication and tailor their practice style to meet patients' needs. | |
15863419 | An unusual case of weight loss in a patient with refractory rheumatoid arthritis. | 2005 May | We describe a case of metastatic malignant melanoma with no primary cutaneous lesion presenting as weight loss in a man with refractory, seropositive rheumatoid arthritis (RA). The patient had undergone multiple investigations previously and the case highlights the importance of repeat assessment in elderly patients presenting with unexplained weight loss. | |
16483360 | Rationale and design of The Delphi Trial--I(RCT)2: international randomized clinical trial | 2006 Feb 16 | BACKGROUND: Rheumatoid arthritis is a chronic inflammatory disease, which affects 1% of the population. Hands and feet are most commonly involved followed by the cervical spine. The spinal column consists of vertebrae stabilized by an intricate network of ligaments. Especially in the upper cervical spine, rheumatoid arthritis can cause degeneration of these ligaments, causing laxity, instability and subluxation of the vertebral bodies. Subsequent compression of the spinal cord and medulla oblongata can cause severe neurological deficits and even sudden death. Once neurological deficits occur, progression is inevitable although the rapidity of progression is highly variable. The first signs and symptoms are pain at the back of the head caused by compression of the major occipital nerve, followed by loss of strength of arms and legs. The severity of the subluxation can be observed with radiological investigations (MRI, CT) with a high sensitivity. The authors have sent a Delphi Questionnaire about the current treatment strategies of craniocervical involvement by rheumatoid arthritis to an international forum of expert rheumatologists and surgeons. The timing of surgery in patients with radiographic instability without evidence of neurological deficit is an area of considerable controversy. If signs and symptoms of myelopathy are present there is little chance of recovery to normal levels after surgery. DESIGN: In this international multicenter randomized clinical trial, early surgical atlantoaxial fixation in patients with rheumatoid arthritis and radiological abnormalities without neurological deficits will be compared with prolonged conservative treatment. The main research question is whether early surgery can prevent radiological and neurological progression. A cost-effectivity analysis will be performed. 250 patients are needed to answer the research question. DISCUSSION: Early surgery could prevent serious neurological deficits, but may have peri-operative morbidity and loss of rotation of the head and neck. The objective of this study is to identify the best timing of surgery for patients at risk for the development of neurological signs and symptoms. |
