16766091 | [Pseudo-Sjogren's syndrome and bulimia]. | 2006 Sep | INTRODUCTION: Bilateral parotid enlargement are presenting features of some metabolic and systemic disease but also of chronic emesis. CASE RECORD: A 24-year old woman consulted during three years many physicians asking for the treatment of a painless parotid swelling confusing with a Sjogren's syndrome. After an initial denial, the weight history, alteration of tooth wear and hypokaliemia conducted to admit a self inducing vomiting with bulimia nervosa. CONCLUSION: Gender, young age, weight history, tooth alteration and electrolytic disorders are the main diagnostic tool of this dissimulated etiology of parotid swelling. | |
16871352 | Pulmonary hypertension in a patient with adult-onset Stills disease. | 2007 Aug | Pulmonary manifestations of adult-onset Still's disease (AOSD) include aseptic pneumonitis, pleural effusions, rarely acute respiratory distress syndrome, and restrictive lung disease. Pulmonary arterial hypertension (PAH) occurs with several rheumatologic diseases, however, has only been reported once in AOSD. We describe a 29-year-old woman with a 9-year history of AOSD, who developed PAH without any other obvious cause. Therefore, we conclude that this is likely a result of pulmonary vascular changes related to AOSD. | |
16255053 | Cat-scratch disease-associated arthropathy. | 2005 Nov | OBJECTIVE: To characterize the articular manifestations of cat-scratch disease (CSD) and to evaluate the long-term clinical outcome of those manifestations. METHODS: A community- and hospital-based surveillance study of CSD was conducted in Israel between 1991 and 2002. CSD was defined as present in a patient when a compatible clinical syndrome and a positive confirmatory finding of Bartonella henselae (by serology and/or polymerase chain reaction) were identified. CSD patients with arthropathy (arthritis/arthralgia) that limited or precluded usual activities of daily living constituted the study group. Patients were followed up until > or =6 weeks after resolution of symptoms, or if symptoms persisted, for >/=12 months. CSD patients without arthropathy served as controls. RESULTS: Among 841 CSD patients, 24 (2.9%) had rheumatoid factor-negative arthropathy that was often severe and disabling. Both univariate and multivariate analyses identified female sex (67% of arthropathy patients versus 40% of controls; relative risk [RR] 2.5, P = 0.047), age older than 20 years (100% of arthropathy patients versus 43% of controls; RR 4.9, P = 0.001), and erythema nodosum (21% of arthropathy patients versus 2% of controls; RR 7.9, P = 0.001) as variables significantly associated with arthropathy. Knee, wrist, ankle, and elbow joints were most frequently affected. Ten patients (42%) had severe arthropathy in the weight-bearing joints, which substantially limited their ability to walk, and 4 of these patients were hospitalized. All of the patients had regional lymphadenopathy, 37.5% had nocturnal joint pain, and 25% had morning stiffness. Nineteen patients (79.2%) recovered after a median duration of 6 weeks (range 1-24 weeks), whereas 5 patients (20.8%) developed chronic disease persisting 16-53 months (median 30 months) after the onset of arthropathy. CONCLUSION: This is the first comprehensive study of arthropathy in CSD. CSD-associated arthropathy is an uncommon syndrome affecting mostly young and middle-age women. It is often severe and disabling, and may take a chronic course. | |
17611457 | Radiosynovectomy in the treatment of chronic exsudative arthritis. | 2005 Aug 30 | Background. Radiosynovectomy (radiosynoviorthesis) is an important instrument for the effective local treatment of chronic inflammatory joint disease, and provides an alternative to surgical synovectomy. Radiosynovectomy leads to the restoration of synovium in the treated joint, with improved joint function due to reduction of pain, swelling and stiffness. The radiopharmaceutical agent used in the treatment of the knee joint is yttrium90-citrate colloid. Material and methods. We studied 32 patients treated with 90Y -synovectomy of the knee between June and October 2004. 28 of these patients were suffering from rheumatoid arthritis, while 4 had chronic post-traumatic joint synovitis. All patients underwent 2-phase scintigraphy and ultrasound examination of the knee before and 6 months after the administration of 5 mCi 90Y-citrate. Results and Conclusions. Symptomatic relief and functional improvement of the treated knees were observed in 83% of the patients. | |
16552589 | A critical appraisal of radiographic scoring systems for assessment of juvenile idiopathic | 2006 Aug | Assessing structural damage to joints over time is essential for evaluating the effectiveness of therapeutic interventions for patients with inflammatory arthritis. Although radiography is able to quantify joint damage, the changes found with conventional radiography early in the disease course are nonspecific, and late radiographic changes are often irreversible. Although many clinical trials on drug development for children still use radiographic scales as endpoints for the study, more specific therapies have been developed for juvenile idiopathic arthritis (JIA) that would enable imaging to "fine-tune" patients to placement into specific treatment algorithms. As a result, new imaging scales to identify early abnormalities are clearly needed. Many pediatric rheumatology centers around the world persistently apply adult-designed radiographic scoring systems to evaluate the progression of JIA. Few pediatric-targeted radiographic scales are available for assessment of progression of JIA in growing joints, and the clinimetric and psychometric properties of such scales have been poorly investigated. We present a critique to the evaluative, discriminative, and predictive roles of the van der Heijde modification of Sharp's radiographic method, a scale originally designed to assess damage to joints of adults with rheumatoid arthritis, when it is applied to a pediatric population. We discuss the advantages and drawbacks of this radiographic scoring system for assessing growing joints and the ability of MRI to overcome inadequacies of conventional radiography. | |
15691065 | Chronobiological and chronopharmacological studies of ketoprofen and its solid dispersion | 2005 Jan | Chronobiology of rheumatoid arthritis (RA) was studied using a standard adjuvant arthritis animal model. Chronopharmacology of ketoprofen, and its solid dispersion forms was also studied. Temporal variations in the degree of articular inflammation (paw volume) and progression of articular destruction were studied by injecting Freund's Complete Adjuvant (FCA) at 0800 and 2000 hrs. Temporal variations in anti-inflammatory effects and ulcerogenic effect were also studied by administration of plain ketoprofen (20 mg/kg) and its solid dispersion with hydroxypropyl beta-cyclodextrin (equivalent to 20 mg/kg of ketoprofen) at the same time points (0800 and 2000 hrs) twice weekly for 22 days. Solid dispersion of ketoprofen was found to be more effective in inhibiting progression of RA. The incidence and severity of ulcers was found to be less with the solid dispersion. The protective effect of ketoprofen and its solid dispersion was significantly higher when these were administered at 0800 hrs. The incidence of ulceration was more in 2000 hrs group. Thus, it was observed that in the adjuvant induced arthritis model, inflammation and articular damage was significantly greater in the rest period of diurnally active rats than in the activity phase. KPF and its solid dispersion showed better protection from inflammation in the morning than in the evening. | |
17029103 | Serum levels and pharmacodynamics of methotrexate and its metabolite 7-hydroxy methotrexat | 2005 | Methotrexate (MTX) is the first-choice drug for rheumatoid arthritis (RA); however, the pharmacodynamics of MTX in Japanese patients with RA treated legitimately according to the government recommended dosage, 6 mg per week, are unknown. Methotrexate and its metabolite, 7-hydroxy MTX (7-OH MTX), were measured in sera of 16 outpatients with active RA in the first week of MTX treatment and 4-12 weeks after the introduction at 0, 1, 2, 4, and 8 h after administration of the first and the third 2-mg capsule, followed by sampling at 48, 96, and 168 h. The mean maximal serum drug concentration (mean C(max)) of MTX attained at 1-2 h after ingestion of the first capsule was 0.215 and 0.252 microM, respectively, in the first and the follow-up week. The mean C(max) after ingestion of the third capsule was 0.223 microM and 0.357 microM. The mean C(max) of 7-OH MTX was 0.0334 and 0.0289 microM for the first capsule, and 0.0495 and 0.0672 microM for the third capsule. The results indicate that MTX does not accumulate or deposit in the body of Japanese patients with RA when treated with 6 mg per week, and pharmacodynamics of MTX are comparable to those in overseas patients treated with 7.5 mg per week. | |
21794317 | [Development and validation of a satisfaction questionnaire in patients with rheumatoid ar | 2006 May | OBJECTIVE: The aim of this study was to develop and validate a specific tool to assess satisfaction with treatment in patients with rheumatoid arthritis (RA). MATERIAL AND METHODS: The questionnaire was developed in three stages: firstly, a literature review was performed by experts in developing patient-centered measures; secondly, items selected by 4 experts in RA were assessed for comprehensibility, format and applicability, and thirdly, administration of the questionnaire was evaluated through a personal interview of a group of 14 patients with RA under treatment with infliximab. Validation of the questionnaire was performed in patients with RA who met the ACR criteria, were older than 18 years, and had started treatment with infliximab due to inadequate disease control. Questionnaires were administered at the baseline visit (beginning of treatment) and at 2, 6 and 14 weeks, coinciding with infliximab infusions. The questionnaire validity was evaluated in terms of construct validity (factorial analysis) and content validity. Content validity was assessed by analysing the relationship between satisfaction and different measures used for treatment effectiveness as well as fulfillment of treatment expectations. RESULTS: Validation of the questionnaire was performed in a sample of 180 patients with a mean (SD) age of 52 (13) years. A total of 80.7% were women. In 72.4% disease duration was longer than 3 years. The scores obtained on the satisfaction questionnaire were related to the aspects defined as ACR criteria (except ESR and CRP), fulfillment of ACR20, ACR50 and ACR70 response criteria, and fulfillment of treatment expectations (p<0,01). DISCUSSION: The results confirm the questionnaire's validity in assessing patient satisfaction with RA treatment, both in routine clinical practice and in research conditions. | |
15829243 | Recent findings on genes associated with inflammatory disease. | 2005 Jun 3 | Inflammatory diseases encompass a variety of medical conditions. In this chapter, autoimmune diseases and allergic disorders will be our focus. The autoimmune diseases include organ-specific autoimmunities, such as type I diabetes mellitus and autoimmune thyroiditis (AITD), and organ non-specific disorders such as systemic lupus erythematosus (SLE). All of them seem to share aspects of aberrant immunologic tolerance toward self-antigens. Asthma and atopic diathesis are among the allergies. Crohn disease and SLE are relatively rare with a prevalence of 10-50 per 100,000, and rheumatoid arthritis (RA), psoriasis, AITD and asthma are commoner with a prevalence of 500 per 100,000 or much higher. The difference among ethnic groups is not prominent for rheumatoid arthritis, psoriasis, AITD or asthma, but Crohn disease and SLE affect some ethnic populations more than others. Although all of these disorders have some environmental component, asthma and atopy seem most affected by environmental factors, as is suggested by the significant increase in their incidence over the last several decades with changes in various environmental factors, especially in developed countries. Over the last 10 years, multiple linkage studies revealed many disease-linked loci throughout the genome with various consistencies. As implicated by some pathophysiological studies of inflammatory immune system related disorders, certain loci are involved in multiple disorders. In the following sections, reports on the identification of disease-associated genes or markers will be summarized for individual diseases (cytotoxic T lymphocyte-associated 4 (CTLA4), CARD15, DLG5, SLC22A4/A5, programmed cell death 1 (PDCD1), RUNX1, SLC9A3R1/NAT9, PADI4, ADAM33, DPP10, PHF11 and GPRA), followed by a discussion of the genes that have been implicated in multiple disorders. | |
15830789 | [Use of infliximab in patients of a rheumatologic center]. | 2005 | The objective of this study was to obtain post-marketing information about the use of infliximab in an ambulatory setting. We studied--retrospectively and prospectively--the case records of patients with rheumatoid arthritis (n=37), psoriatic arthritis (n=5), mixed connective tissue disease (n=1), and ankylosing spondylitis (n=2) who received infliximab (3 mg/kg) from August 2000 to January 2003. Descriptive values were given as percentage, mean or median, and standard deviation or interquartile range. Wilcoxon test was used for paired analysis of pre/post doses of corticosteroids, non-steroidal anti-inflammatory drugs, and methotrexate therapy. A p value < or = 0.05 was considered significant. Forty-five patients were included. A total of 207 infusions were administered. In 4 patients the treatment was permanently discontinued due to severe back pain during the infusion (2 cases) and serious anaphylactic reactions (2 cases). Other adverse reactions occurring during infusions were mild and successfully managed with standard treatment. A case of staphylococcal septic arthritis resolved with standard antibiotic treatment. No patient had evidence of active tuberculosis. One patient with rheumatoid arthritis and chronic renal insufficiency, received treatment with infliximab 1.9 mg/kg, every 30 days, with no changes in renal function. Due to improvement of symptoms, 14/39 (35.9%) patients could decrease the doses of corticosteroids, 15/43 (34.8%) decreased the doses of antiinflammatory drugs and 12/34 (35.3%) decreased methotrexate dosage. Although some questions remain to be elucidated, this case series shows the drug safety profile, the possibility to reduce concomitant drug doses, as well as individual approaches for situations where there are not yet guidelines available, so that rheumatologists have to make decisions based on clinical needs. | |
16951720 | Keishibukuryogan (gui-zhi-fu-ling-wan), a Kampo formula, decreases disease activity and so | 2006 Sep | An increasing death rate due to cardiovascular disease in patients with rheumatoid arthritis (RA) has been reported. Keishibukuryogan (KBG) is a traditional Chinese/Japanese (Kampo) formula that has been administered to patients with blood stagnation, e.g. thrombotic disease and atherosclerosis. The objective of this study was to evaluate the efficacy of KBG on disease activity and endothelial dysfunction in RA patients. Sixteen RA patients were enrolled and administered KBG (12 g per day) for 12 weeks in addition to continuing other drugs. The disease activity of RA was assessed by modified disease activity scores for 28 joints (DAS(28)). Plasma levels of adhesion molecules, soluble E-selectin (sE-selectin), soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) were evaluated. C-reactive protein (CRP), inflammatory cytokines (IL-1beta, IL-6 and TNF-alpha) and lipid peroxide (LPO) were also evaluated. Fourteen patients completed the study. The disease activity of RA, tender joint count, swollen joint count and DAS(28) decreased significantly. Among adhesion molecules, only sVCAM-1 decreased significantly. LPO also decreased significantly, whereas CRP and inflammatory cytokines remained unchanged. These results suggest that KBG has insufficient anti-inflammatory or immunomodulating effect but does have a beneficial effect on articular symptoms and a protective effect against endothelial dysfunction in RA patients. | |
16543040 | Fever of unknown origin: temporal arteritis presenting with persistent cough and elevated | 2006 Mar | BACKGROUND: Fever of unknown origin (FUO) at the present time is most frequently caused by neoplasm and less commonly by infection. Currently, collagen vascular diseases (CVDs) are an uncommon cause of FUO because most are readily diagnosable by serologic methods and do not remain undiagnosed for sufficient time to present as FUOs. CVDs presenting as FUOs not readily diagnosable with specific tests include late-onset rheumatoid arthritis, adult juvenile rheumatoid arthritis, and polymyalgia rheumatica/temporal arteritis (TA). TA, or giant cell arteritis, is an uncommon arteritis of the mid- and large-sized extracranial arteries of the head and neck and is a rare cause of FUO. TA is characterized by headache, scalp tenderness, jaw pain on chewing, and sudden loss of vision. Fever, anorexia, weight loss, and night sweats may also be present. With TA, respiratory symptoms occur in 9% and are the presenting feature in 4%. Laboratory abnormalities associated with TA include a highly elevated erythrocyte sedimentation rate, anemia, and thrombocytosis, and mildly increased alkaline phosphatase/serum transaminases. PATIENT: We present a patient with FUO caused by TA whose predominant presenting symptom was persistent cough that overshadowed head and neck symptoms of TA. To the best of our knowledge, this is the first case of TA presenting as an FUO, with a highly elevated serum ferritin level. RESULTS: We conclude that highly elevated serum ferritin levels in patients with FUO should alert the clinician to consider TA in the differential diagnosis. | |
16217592 | Aortic valve insufficiency in patients with chronic rheumatic diseases. | 2006 May | Aortic valve lesions are often found in patients with rheumatic diseases, but their clinical significance has not been properly evaluated. In the present study, the echocardiographic files of the cardiology unit of the Oulu University Hospital were screened for a diagnosis of aortic insufficiency (AI). The aetiology of the valve disease and specific details of the rheumatic disease were evaluated in 160 patients. Twenty-eight patients (18%) had a history of rheumatic fever. Rheumatic disease was found in 14 patients (8.8%) with AI, which is significantly more than the prevalence of rheumatic diseases (1.8%) in the corresponding age group (35-100 years) in Finland. Rheumatoid arthritis or juvenile rheumatoid arthritis was found in seven patients (4.4%), whereas ankylosing spondylitis or seronegative spondylarthropathy were found in four patients (2.5%). Other rheumatic diseases included Takayasu's arteritis (two patients) and scleroderma (one patient). When 38 patients with pure AI without other possible aetiology were analysed, rheumatic disease was found in five patients (13%). Patients with rheumatic disease as a potential aetiology of AI often had symptomatic valve disease, which required surgical treatment, although great differences between different aetiologies were not found. | |
16099106 | Aggrecanase-1 (ADAMTS-4) interacts with alpha1-antitrypsin. | 2005 Sep 15 | In degradative articular diseases such as rheumatoid arthritis and osteoarthritis, loss of the extracellular matrix occurs, resulting in the destruction of joint cartilage. Proteolysis of aggrecan is one of the early events that leads to breakdown of the extracellular matrix. Aggrecanase-1 (ADAMTS--4) is considered to play a pivotal role in the abrasion of cartilage aggrecan in rheumatoid arthritis and osteoarthritis. To identify an endogenous inhibitor of aggrecanase-1, we performed a yeast two-hybrid screen using the catalytic domain of human aggrecanase-1 as a bait and transformed an EGY 48 yeast strain carrying the bait plasmid with a human liver cDNA library plasmid. This screen identified alpha1-antitrypsin, a member of the family of plasma serine proteinase inhibitors, as a prey. Recombinant aggrecanase-1 and alpha1-antitrypsin were expressed in mammalian cells and used in co-immunoprecipitation experiments, which showed that full-length aggrecanase-1 and alpha1-antitrypsin are also associated in vivo. However, aggrecanase-1 did not interfere with the inhibitory activity of alpha1-antitrypsin against elastase, and alpha1-antitrypsin had no effect on the proteolytic activity of aggrecanase-1. Taken together, these data suggest that aggrecanase-1 and alpha1-antitrypsin bind in vivo, although the physiological significance of the interaction between aggrecanase-1 and alpha1-antitrypsin remains unclear. | |
16038750 | Pneumococcal meningitis and etanercept--chance or association? | 2005 Aug | Rheumatoid arthritis is a severe deforming chronic disease which has major implications for mortality and quality of life. Agents with anti-tumour necrosis factor alpha (TNFalpha) activity are a new modality of therapy, which can significantly reduce the acute inflammation in this condition. However, TNFalpha is a cytokine involved in initiating the protective immune response; consequently, patients receiving this therapy are at increased risk of infection. Etanercept is a recombinant form of the p75 TNF receptor (TNF-RII) dimerised by fusion with a portion of the human IgG1 Fc tail with anti-TNFalpha activity. We report the first case of a patient with rheumatoid arthritis who developed pneumococcal meningitis whilst on etanercept, suggesting a possible association between etanercept and this severe life threatening infection. | |
15965822 | [Reducing toxicity of methotrexate with folic acid]. | 2005 Jun | BACKGROUND: Methotrexate is considered to have the best ratio of efficacy to toxicity of the disease modifying antirheumatic drugs. Recently it has been shown to enhance the life expectancy of patients with rheumatoid arthritis. Some 30-60% of RA patients discontinue MTX treatment within 1 year because of side-effects. In this review, the current data about supplementation with folate or folinic acid and their effect on the toxicity and efficacy of low-dose methotrexate therapy are analysed. METHODS: A Medline search was performed using "folate", "folic acid", "folinic acid", "homocysteine", "methotrexate", "cardiovascular", "heart infarction" and "rheumatoid arthritis" as search terms. The relevant literature was reviewed and other papers referred to as references were explored. CONCLUSION: Both folate and folinic acid reduce methotrexate toxicity and the discontinuation rate, and decrease methotrexate-induced hyperhomocysteinemia. Folate is less expensive, more secure and easier to handle than folinic acid. The efficacy of methotrexate probably decreases slightly, but the benefit outweighs the risk. Folate supplementation should, therefore, be routinely prescribed to every patient taking low-dose methotrexate. | |
17124681 | Toxocariasis seroprevalence in patients with rheumatoid arthritis. | 2005 | Rheumatoid arthritis (RA) is a chronic inflammatory disease for which immunogenetic susceptibility factors have been defined. The aim of this study was to investigate seroprevalence of Toxocara canis (T. canis) in patients with RA. Forty-five patients with RA who were all diagnosed according to the ACR criteria and 48 health controls were included in this study. The mean age of patients with RA and of controls was 50+/-14 and 49+/-13, respectively. In both groups T. canis IgG antibodies were investigated with ELISA. Toxocara canis seroprevalence in patients with RA (35.6%) was significantly higher than that in the control group (8.3%) (p=0.001). There was no significant difference between patients with RA and control group in terms of behavioral factors (except in frequency of hand washing), demographic and socio-economic factors, while there was a difference in terms of owning dogs and cats or in the duration of ownership. When the patients with RA were divided into seropositive and seronegative, there were no significant differences between both groups in terms of demographic factors, socio-economic factors, behavioral factors, owning dogs and cats or duration of ownership and active or remission state of the illness, duration of disease and disability level in patients with RA (p > 0.05). In view of the present results, it is suggested that Toxocara infection was acquired before RA had developed and that high seroprevalence may result from exposure to pets and soil. It seems that this subject requires further investigations with larger numbers of samples in order to fully evaluate the causes of high seropositivity. | |
16132687 | Free radical scavenging activity of Cleome gynandra L. leaves on adjuvant induced arthriti | 2005 Aug | The generation of free radicals has been implicated in the causation of several diseases of known and unknown etiologies such as, rheumatoid arthritis, diabetes, cancer, etc., and compounds that can scavenge free radicals have great potential in ameliorating these disease processes. The present study was aimed to investigate the possible anti-oxidant potential of Cleome gynandra leaf extract at a dose of 150 mg/kg body weight for 30 days on adjuvant induced arthritis in experimental rats. Oral administration of C. gynandra leaf extract significantly increased the levels of lipid peroxides and activities of catalase, glutathione peroxidase and decreased the levels of reduced glutathione and superoxide dismutase activity in arthritis induced rats. The free radical scavenging activity of the plant was further evidenced by histological observations made on the limb tissue. The presence of biologically active ingredients and vital trace elements in the leaves readily account for free radical scavenging property of C. gynandra. | |
17127195 | Infection and musculoskeletal conditions: Infectious arthritis. | 2006 Dec | In contrast to the outstanding achievements made in therapy for autoimmune arthritides, not least rheumatoid arthritis, the pace of progress in therapy for infectious arthritis remains slow. This has primarily to do with the complex task of, on the one hand, killing the invading microorganisms and, on the other, to down-regulate the exaggerated immune response which participates in the microbial clearance but at the same time contributes to the tissue destruction. The use of experimental models of microbial arthritides has clarified several bacterial virulence factors as well as many haematopoietic cell types and their products that are involved in the pathogenesis of joint infection. Recent studies have documented that T-cell-mediated responses are not only prominent but also decisive with respect to disease sequelae. This chapter also reviews the primarily protective non-antigen-specific immune responsiveness to microbial agents, including the impact of neutrophils, complement system, and nitric oxide. The knowledge gained regarding microbial virulence factors and the host immune responses has prompted researchers to develop new strategies on how to interact in vivo with the infectious process. Some of these approaches are commented upon in this review: e.g. vaccination procedures to prevent septic arthritis and sepsis, as well as therapeutic procedures to minimize joint damage during an ongoing infection. | |
16277703 | The 3rd International Meeting on Gene Therapy in Rheumatology and Orthopaedics. | 2005 | The 3rd International Meeting on Gene Therapy in Rheumatology and Orthopaedics was held in Boston, Massachusetts, USA in May 2004. Keystone lectures delivered by Drs Joseph Glorioso and Inder Verma provided comprehensive, up-to-date information on all major virus vectors. Other invited speakers covered the application of gene therapy to treatment of arthritis, including the latest clinical trial in rheumatoid arthritis, as well as lupus and Sjögren's syndrome. Applications in mesenchymal stem cell biology, tissue repair, and regenerative medicine were also addressed. The field has advanced considerably since the previous meeting in this series, and further clinical trials seem likely. |
