15292531 The impact of low family income on self-reported health outcomes in patients with rheumato 2004 Nov OBJECTIVE: Self-rated health (SRH) is an independent, strong predictor of morbidity and mortality. Socio-economic status (SES) is strongly associated with SRH. This study investigated the relationship between SES and SRH outcomes in a sample of patients with rheumatoid arthritis (RA) in Canada. METHODS: Both generic preference-based [Health Utilities Index Mark 3 (HUI3) and Short Form 6D (SF-6D)] and non-preference-based [disease-specific (Rheumatoid Arthritis Quality of Life, RAQoL) and a functional status (Health Assessment Questionnaire, HAQ)] SRH questionnaires were administered to 313 RA patients. Both proximate (education and annual household income) and contextual (neighbourhood income, education and unemployment) measures of SES were captured. Ordinary least squares (OLS) regression was used to adjust for RA severity while assessing the relationship between SRH and SES measures. Two-stage least-squares (TSLS) regression was used to determine if there was an inter-relationship between SES and SRH measures. RESULTS: The sample was well distributed across RA severity and SES measures. Contextual and proximate measures of SES were poorly correlated. Lower levels of proximate SES measures (but not contextual) were associated with poorer SRH outcomes. The OLS regressions showed significant associations between the HUI3 and the SF-6D overall scores and the HAQ for self-reported income. The RAQoL did not differ significantly across SES. TSLS regression confirmed the finding that self-reported income was similarly associated with the SRH measures. CONCLUSIONS: Even in a country with universal access to health-care, the impact of a chronic disease such as RA on SRH is associated with self-reported income. The finding that preference-based measures vary with income independently of RA severity could bias economic evaluation.
12090374 Recent advances and future directions in the biopsychosocial assessment and treatment of a 2002 Jun This article provides an overview of the emerging literature on biopsychosocial assessment and treatment for two of the most common forms of arthritis: osteoarthritis and rheumatoid arthritis. The article is divided into 3 parts. In the 1st part, the basic elements of the biopsychosocial approach to assessing and treating persons having arthritis is described. In the 2nd part, the authors evaluate studies of biopsychosocial approaches to the assessment of arthritis pain and disability. Six research areas are reviewed: learned helplessness, depression, stress, pain coping, self-efficacy, and the social context of arthritis. The 3rd part of the article reviews studies that testing the efficacy of biopsychosocial treatment approaches for persons having osteoarthritis and rheumatoid arthritis.
12833157 Functional haplotypes of PADI4, encoding citrullinating enzyme peptidylarginine deiminase 2003 Aug Individuals with rheumatoid arthritis frequently have autoantibodies to citrullinated peptides, suggesting the involvement of the peptidylarginine deiminases citrullinating enzymes (encoded by PADI genes) in rheumatoid arthritis. Previous linkage studies have shown that a susceptibility locus for rheumatoid arthritis includes four PADI genes but did not establish which PADI gene confers susceptibility to rheumatoid arthritis. We used a case-control linkage disequilibrium study to show that PADI type 4 is a susceptibility locus for rheumatoid arthritis (P = 0.000008). PADI4 was expressed in hematological and rheumatoid arthritis synovial tissues. We also identified a haplotype of PADI4 associated with susceptibility to rheumatoid arthritis that affected stability of transcripts and was associated with levels of antibody to citrullinated peptide in sera from individuals with rheumatoid arthritis. Our results imply that the PADI4 haplotype associated with susceptibility to rheumatoid arthritis increases production of citrullinated peptides acting as autoantigens, resulting in heightened risk of developing the disease.
15304675 The effect of individualized diet challenges consisting of allergenic foods on TNF-alpha a 2004 Nov OBJECTIVE: To investigate the effect of individualized diet challenges consisting of allergenic foods, defined by the skin prick test (SPT), on tumour necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta) levels in patients with rheumatoid arthritis (RA). METHODS: Twenty patients with a positive SPT response for food extracts and 20 with a negative SPT response were enrolled. None of the patients had active disease. All patients were fasted for the most common allergenic foods for 12 days and then allocated to two groups according to SPT results. Food challenges were performed with allergenic foods in the prick-positive group (PPG) and with corn and rice in the prick-negative group (PNG) for a period of 12 days. Then, allergenic foods were excluded from the PPG patients' diet and corn and rice were removed from the PNG patients' diet. Clinical examinations were performed after fasting (baseline), at the end of the challenge phase and at the end of the re-elimination phase. Stiffness, pain, tender and swollen joint counts, health assessment questionnaire (HAQ), Ritchie's articular index, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and serum TNF-alpha and IL-1beta levels were measured. RESULTS: TNF-alpha (P < 0.01), IL-1beta (P < 0.05), ESR (P < 0.05) and CRP (P = 0.001) levels and all of the clinical variables, except HAQ, were increased with food challenges in the PPG. These increases were also recorded after the re-elimination phase. In the PNG, no significant change was seen in any of the variables, except pain (P < 0.05). During the study, important differences were observed for most of the variables between the two groups. Thirteen (72%) patients in the PPG and three (18%) in the PNG experienced disease exacerbation with challenges. This aggravation continued after elimination. CONCLUSIONS: Our results suggest that individualized dietary revisions may regulate TNF-alpha and IL-1beta levels in selected patients with RA.
12687513 Declining use of orthopedic surgery in patients with rheumatoid arthritis? Results of a lo 2003 Apr 15 OBJECTIVE: To describe the use of orthopedic surgery, including joint replacement surgery, in a well-defined, population-based cohort of patients with rheumatoid arthritis (RA) and to identify characteristics that predict such use. METHODS: A retrospective medical record review was performed of cases of RA incident in Rochester, Minnesota, during the years 1955-1995. All joint surgeries were recorded. RESULTS: Of the total 609 RA incident cases, 242 patients underwent 1 or more (maximum of 20/patient) surgical procedures involving joints during their followup. Overall, this RA cohort had 7.4 surgeries per 100 person-years of followup; the cumulative incidence for joint surgery for RA-related joint disease at 30 years was 33.7% +/- SEM 3.8%. The risk of having a disease-related joint surgery for RA is increased in patients who are women, younger, positive for rheumatoid factor, and have rheumatoid nodules. When adjusted for duration of followup, patients with RA diagnosed after 1985 were significantly less likely to have undergone joint surgery for RA (P < 0.001). Survival of patients who underwent total joint arthroplasty was similar to those who did not. CONCLUSION: Reconstructive surgeries are common in RA, although patients diagnosed after 1985 are less likely to require joint surgery. These findings may reflect trends in medical disease management and have importance for health care resource utilization planning.
11927833 Polymorphisms in the methylenetetrahydrofolate reductase gene were associated with both th 2002 Apr 5,10-Methylenetetrahydrofolate reductase (MTHFR), a key enzyme involved in folate metabolism, has two common polymorphisms that affect enzyme activity. The objective of this study was to examine whether there was a correlation between the genotype or haplotype of the MTHFR gene and the efficacy or toxicity of methotrexate (MTX) in the treatment of rheumatoid arthritis. MTX-treated rheumatoid arthritis patients (n = 106) were selected from outpatient clinics and used for a retrospective study to examine the correlation between genotypes or haplotypes concerning polymorphisms of the MTHFR gene, and the efficacy or toxicity of MTX. Estimation of the haplotype frequencies was performed by maximum likelihood estimation based on expectation maximization algorithm. Single locus analysis examining each locus separately showed that patients with 1298C were receiving significantly lower doses of MTX compared to patients without [P < 0.05, relative risk (RR) = 2.18, 95% confidence interval (CI) 1.17-4.06], while a higher rate of overall MTX toxicity was observed in patients with 677T than those without (P < 0.05, RR = 1.25, 95% CI 1.05-1.49). An estimation of haplotype frequencies showed that there was no 677T-1298C haplotype in the population. Posterior distribution of the diplotype configuration for each individual was concentrated on a single configuration. Patients with the 677C-1298C haplotype were receiving lower doses of MTX than those without (P < 0.05, RR = 2.14, 95% CI 1.13-4.07), while subjects with 677T-1298A had a higher frequency of side-effects from MTX (P < 0.05, RR = 1.42, 95% CI 1.11-1.82). Both single locus and haplotype analyses suggest that polymorphisms within the MTHFR gene are associated with both the efficacy and toxicity of MTX in rheumatoid arthritis patients. Pharmacokinetic studies are necessary to prove the association.
12508780 Lymphoepithelioma-like carcinoma of the parotid gland in a patient with rheumatoid arthrit 2002 Nov Lymphoepithelioma-like carcinoma (LELC) is an Epstein-Barr virus (EBV) related malignancy. It is not a common condition and is usually found in the head and neck region. We describe the development of LELC involving the parotid gland in a patient with rheumatoid arthritis (RA) who had been receiving long-term azathioprine. A brief review is also made on the clinical presentation and histological features of LELC and the association of RA with EBV related diseases. The latter may be attributed to an increase in risk of malignancy associated with RA or as a result of the long-term immunosuppressive used.
12136908 Amyloid arthropathy in the course of multiple myeloma. 2002 Jul OBJECTIVE: Primary amyloidosis is classical in the course of multiple myeloma (MM), but peripheral amyloid arthropathy is unusual. We evaluated the frequency and effect of amyloid arthropathy in a single center series of patients with MM. METHODS: Retrospective analysis of cases of peripheral joint amyloidosis in a cohort of patients with MM. RESULTS: Between 1978 and 1996, 11 patients (6 women, 5 men, mean age 59 yrs) were diagnosed with biopsy proven amyloid arthropathy in a cohort of 311 patients with MM. Arthritis was the first symptom of amyloidosis in all patients and occurred within the 6 months after MM diagnosis in most patients (7/11). Nine patients had light chain MM and X light chain was more common than kappa (6 vs 5). Shoulder hypertrophic arthropathy and rheumatoid arthritis-like polyarthritis were the 2 most common involved sites. In most cases, joint involvement was responsible for major limitations in activities of daily living. Amyloid deposits were clearly visible on magnetic resonance images (MRI), which also showed inflammatory synovitis in some cases. Control of MM was often associated with improvement of amyloid arthropathy, but additional rheumatological treatment--oral low dose prednisone or joint steroid injection--was often needed to achieve more complete relief. Amyloid arthropathy was not associated with decreased survival, except for patients with concomitant cardiac involvement. CONCLUSION: This series provides reliable information on amyloid arthropathy, especially regarding functional effects, anatomical lesions on MRI, and therapeutic options.
12709544 A comparison of ultrasonography and magnetic resonance imaging in the evaluation of tempor 2003 May OBJECTIVE: To define the diagnostic value of ultrasonographic (US) examination in comparison with magnetic resonance imaging (MRI) for the assessment of temporomandibular joint (TMJ) involvement in rheumatoid arthritis (RA) and psoriatic arthritis (PsA). METHODS: MRI and US examinations were performed in 33 patients (22 with RA and 11 with PsA). Alterations of the disc, alterations of the condyle and joint effusion were evaluated. RESULTS: Pathological changes of the TMJ were observed by MRI in 24 patients and by US in 31 patients. The sensitivity and specificity of US were calculated in comparison with MRI. The sensitivity was 72.2% and the specificity was 60% in the assessment of pathological changes of the TMJ. The sensitivity was 69.6% with specificity of 30.0% in the assessment of alterations of the disc; the sensitivity was 70.6% with specificity of 75.0% in the assessment of joint effusion. Significant concordance was not observed in the assessment of condylar alterations. CONCLUSIONS: US imaging appears able to detect different pathological changes of the TMJ and may be considered an important diagnostic tool for clinical evaluation of the TMJ in RA and PsA.
15194574 Lack of radiological and clinical benefit over two years of low dose prednisolone for rheu 2004 Jul BACKGROUND: Evidence for disease modifying activity of low dose corticosteroid treatment in rheumatoid arthritis is contradictory. Studies showing radiological benefit suggest that continued treatment is required to sustain the effect. OBJECTIVE: To evaluate the effect of low dose oral prednisolone in early rheumatoid arthritis on disease activity over two years. DESIGN: Double blind placebo controlled trial. METHODS: Patients with rheumatoid arthritis, duration <3 years (n = 167), were started on a disease modifying antirheumatic drug (DMARD; sulphasalazine) and allocated by stratified randomisation to prednisolone 7 mg/day or placebo. Primary outcome measure was radiological damage, assessed by the modified Sharp method. Clinical benefit was a secondary outcome. A proactive approach to identifying and treating corticosteroid adverse events was adopted. Patients who discontinued sulphasalazine were offered an alternative DMARD. RESULTS: 90 of 257 patients eligible for the study refused to participate (more women than men). Of those enrolled, 84% were seropositive for rheumatoid factor, median age 56 years, median disease duration 12 months, female to male ratio 1.8:1. Prednisolone was given to 84 patients; of these 73% continued prednisolone and 70% sulphasalazine at 2 years. Of the 83 patients on placebo, 80% continued placebo and 64% sulphasalazine at 2 years. There were no significant differences in radiological score or clinical and laboratory measures at 0 and 2 years. CONCLUSIONS: Low dose prednisolone conferred no radiological or clinical benefit on patients maintained on a DMARD over two years. Low dose corticosteroids have no role in the routine management of rheumatoid arthritis treated with conventional disease modifying drugs.
12111624 Ultrasound and clinical evaluation of quadricipital tendon enthesitis in patients with pso 2002 Jun Enthesitis is an inflammatory lesion of the tendon, ligament and capsular insertions into the bone, and it is a fundamental element in the diagnosis of spondyloarthropathies. Sonography is the method of choice for studying periarticular soft tissues because it is capable of detecting both the early (oedema, thickening) and the late alterations (erosions and enthesophytes); it is also an inexpensive, biologically harmless and easily repeatable technique. The aim of this study was to compare the prevalence of quadricipital enthesitis in psoriatic arthritis (PsA) and rheumatoid arthritis (RA) patients, and to document any clinical and echostructural differences in this lesion between the two diseases. The results show that enthesitis is more frequent in PsA patients, more than half of whom are asymptomatic. Knee inflammation was found in the PsA patients with enthesitis regardless of the concomitant presence of joint effusion; none of the RA patients suffered from enthesitis alone. Quadricipital enthesitis is more frequent in male patients. There was no significant correlation between the presence of peripatellar psoriatic lesions and enthesitis. Sonographic examinations of patients with enthesitis revealed that those with RA had dominantly inflammatory lesions, whereas PsA patients also showed major new bone deposition.
15088288 Concomitant medication use in a large, international, multicenter, placebo controlled tria 2004 Apr OBJECTIVE: To examine the safety of anakinra when added to a background of standard rheumatoid arthritis (RA) medications in patients with RA with active disease. METHODS: This analysis further evaluates data from the first 6 months of a blinded, placebo controlled safety trial that had a subsequent 30 month, open label portion (not reported here). Patients with RA with a wide range of comorbid conditions, disease activity, and background medications were randomly assigned in a 4:1 allocation ratio to treatment with anakinra 100 mg or placebo administered daily by injection. Safety was assessed by comparing adverse event profiles between anakinra and placebo patients according to concomitant medications received. RESULTS: Anakinra patients (n = 1116) showed no difference in the incidence of upper respiratory infections or overall serious adverse events compared with placebo patients (n = 283). The anakinra group had more injection site reactions (72.6% vs 32.9% in placebo) and a small increase in serious infections (2.1% vs 0.4% in placebo). Anakinra's safety profile did not differ in patients receiving antihypertensive, antidiabetic, or statin drugs. CONCLUSION: This study indicates that anakinra has a good safety profile in patients typically seen in a rheumatology practice who are considered candidates for therapy with agents that are immunomodulatory and disease modifying. Except for injection site reactions and a nonstatistically although potentially clinically significant increase in serious infections in the anakinra versus the placebo groups, the addition of anakinra to a stable background regimen of RA medications introduced no other important safety risk in patients with RA.
12739037 Polymorphism of the beta3-adrenergic receptor and lipid profile in patients with rheumatoi 2003 May We investigated the effect of beta 3-adrenergic receptor (beta(3)AR) polymorphism on lipid profiles in patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) treated with chloroquine. One hundred sixty-eight subjects were classified into three groups: 61 RA patients, 57 SLE patients, and 50 healthy subjects. All patients fulfilled the 1987 and 1982 classification criteria for RA and SLE, respectively, of the American College of Rheumatology. Demographic data and clinical characteristics of the patients were registered. Fasting lipid profile determination and leukocyte genomic DNA isolation from peripheral blood was performed in all the participants. Screening of the beta(3)-AR gene polymorphic region (exon 1) was done by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. Quantitative and qualitative variables were analyzed using analysis of variance (ANOVA) with the LSD and chi(2) tests, respectively. An association between the arg64/arg64 beta(3)-AR genotype and high levels of triglycerides (TG) and very low-density lipoprotein cholesterol (VLDL-c) was found in three RA patients ( P=0.01), two of them taking chloroquine. Arg64/arg64 beta(3)-AR polymorphism may contribute to increased TG and VLDL-c in RA patients, independently of chloroquine treatment.
11851101 [Kashin-Beck disease in Israel?]. 2002 Jan This is a case report of a 21 year old young man who suffers from severe early bilateral hip joint osteoarthrosis. Due to this surprising finding we discuss the differential diagnosis between Kashin-Beck disease, an endemic disease of the patients prior living area (east Siberia) and severe hip joint damage secondary to juvenile rheumatoid arthritis and other diseases.
15260090 Cervical laminoplasty for subaxial lesion in rheumatoid arthritis. 2004 Apr Expansive laminoplasty of the cervical spine was performed for 15 patients with subaxial lesion (SAL) in rheumatoid arthritis (RA) with or without symptomatic occipitocervical pathology. Clinical results were satisfactory, and radiographic evaluation revealed that the range of movement of the cervical spine decreased to 56.3%, spinal alignment was well preserved, and intervertebral slipping advanced only slightly. Therefore, expansive laminoplasty is shown to be clinically effective in decompressing the subaxial spinal cord without the need for fusion of this region, yet it avoids exacerbating or creating significant instability. We found that it can serve as a useful procedure for treating spinal cord compression caused by SAL in RA. For patients with upper cervical instability, laminoplasty with upper cervical fusion appears to be an effective option. In a case in which kyphosis was observed preoperatively, its deformity became worse after laminoplasty. Thus, it may be advisable to consider subaxial fusion in such cases.
12953137 Early recurrence of rheumatoid arthritis after nonmyeloablative allogeneic blood stem cell 2003 Sep Allogeneic blood stem cell transplantation with reduced conditioning has been proposed as a new, potentially curative treatment option for patients with rheumatoid arthritis (RA). We report a 60-year-old woman with RA and coexisting multiple myeloma who was treated with high-dose melphalan and autologous blood stem cell transplantation (BSCT) followed by a nonmyeloablative allogeneic BSCT from her healthy dizygotic twin brother. She achieved a complete remission of her RA after autologous BSCT, but relapsed early despite complete donor chimerism following successful allogeneic transplantation with reduced intensity conditioning. This case illustrates that allogeneic BSCT following nonmyeloablative conditioning may be an uncertain option for curing patients with RA.
15002096 Semi-constrained total elbow arthroplasty in Chinese rheumatoid patients. 2003 Dec Seventeen Coonrad-Morrey semi-constrained total elbow replacements were performed on 14 Chinese rheumatoid patients. The elbows were reviewed retrospectively after a mean follow-up of 36 months (range 12-89 months.) After the operation, all patients were satisfied and there was no pain in 15 elbows. There was no radiological sign of loosening in the implanted prostheses and bone graft was incorporated in 93% of primary elbow replacements. The Mayo Elbow Performance Score was improved from an average of 40 (range 20-75) to an average of 93 (range 65-100). The arc of flexion was improved from an average of 89 degrees (range 0 degrees-125 degrees ) to 104 degrees (range 35 degrees-125 degrees ). The sizes of implants can be predicted accurately by the planning template in only four elbows (24%) and there were early complications in seven elbows (41%), with one prosthesis removed because of deep infection.
15248207 Ultrasonography of the metatarsophalangeal joints in rheumatoid arthritis: comparison with 2004 Jul OBJECTIVE: To compare ultrasonography (US) with magnetic resonance imaging (MRI), conventional radiography, and clinical examination in the evaluation of bone destruction and signs of inflammation in the metatarsophalangeal (MTP) joints of patients with rheumatoid arthritis (RA). METHODS: Two hundred MTP joints of 40 patients with RA and 100 MTP joints of 20 healthy control subjects were assessed with B-mode US, contrast-enhanced MRI, conventional radiography, and clinical examination for signs of bone destruction and joint inflammation. RESULTS: With MRI considered the reference method, the sensitivity, specificity, and accuracy of US for the detection of bone erosions were 0.79, 0.97, and 0.96, respectively, while the corresponding values for radiography were 0.32, 0.98, and 0.93. The sensitivity, specificity, and accuracy of US for the detection of synovitis were 0.87, 0.74, and 0.79, while for clinical examination, the corresponding values were 0.43, 0.89, and 0.71. Erosive disease was identified in 26 patients by US, compared with 20 patients by MRI and 11 patients by radiography. Evaluation by US indicated signs of inflammation in 36 patients, while MRI and clinical examination revealed signs of inflammation in 31 patients and 20 patients, respectively. US and MRI volume-based gradings of synovitis showed intraclass correlation coefficients of 0.56-0.72 (P < 0.0001). The MRI and radiographic visualizations of US-detected bone changes were closely related to their size-based gradings on US. CONCLUSION: US enables detection and grading of destructive and inflammatory changes in the MTP joints of patients with RA. By comparison with MRI, US was found to be markedly more sensitive and accurate than clinical examination and conventional radiography. Considering the early and frequent involvement of the MTP joints, evaluation of these joints by US may be of major clinical importance in RA.
12699296 Glucocorticoid-induced osteoporosis. 2003 Mar Therapeutic use of glucocorticoids can lead to many well-known adverse events. Of all potential serious side effects, glucocorticoid-induced osteoporosis (GIOP) is one of the most devastating complications of protracted glucocorticoid therapy in rheumatoid arthritis. GIOP is the most common form of drug-induced osteoporosis. Although much has been written about the association of glucocorticoids with bone disease among patients with chronic inflammatory conditions, many issues remain unsettled. This article focuses on areas of continued controversies, including the epidemiology and pathogenesis of GIOP, specification of a "safe" dose, methods for diagnosis of GIOP, and an evidence-based approach for GIOP prevention.
15157003 Drugs that block tumour necrosis factor: experience in patients with rheumatoid arthritis. 2004 Three biological response modifiers that inhibit tumour necrosis factor-alpha (TNF-alpha) are approved for treating rheumatoid arthritis (RA). Etanercept is a fusion protein comprising two soluble human TNF-alpha receptors linked to the Fc fragment of human immunoglobulin G1. Infliximab is a chimeric (human/mouse) monoclonal antibody and adalimumab is a humanised monoclonal antibody. In placebo-controlled trials in established disease-modifying antirheumatic drug (DMARD)-refractory RA, the anti-TNF-alpha agents have reduced disease activity, as monotherapy or in combination with methotrexate. In long-term, open-label studies with etanercept or adalimumab, clinical response was sustained for up to 5 years. In early RA, etanercept has similar efficacy to methotrexate. However, etanercept was more effective than methotrexate in preventing radiographic progression. Preventing or delaying disease progression and disability with etanercept therapy in early RA may reduce costs associated with long-term disease outcomes. Data also suggest a benefit of infliximab plus methotrexate or adalimumab plus methotrexate in early RA. All three agents have been shown to improve functionality as assessed by health assessment questionnaire (HAQ) disability scores. Health-related quality of life is also improved in terms of physical and mental health and vitality. Furthermore, etanercept and adalimumab are associated with a reduction in fatigue. Long-term etanercept or infliximab therapy is associated with increased job employment and etanercept also reduces healthcare utilisation. Mild, transient injection-site reactions occur in about 33% of patients treated with etanercept and 20% of patients treated with adalimumab. In patients treated with infliximab, 16-20% have infusion reactions. The incidence of serious infection associated with etanercept and infliximab was low, about 2-3% in etanercept studies of up to 5 years duration, and 5% in a survey of more than 10 infliximab trials. This paper reviews the evidence for efficacy, safety and effectiveness of anti-TNF-alpha agents in RA.
