10663761 | Can we see enough? A comparative study of film-screen vs digital radiographs in small lesi | 2000 | The aim of this study was to evaluate the performance of digital radiography in the detection of early very small erosions and joint space narrowing in the hands and feet in rheumatoid arthritis. Fifty-three sets of film-screen and digital radiographs of the same hands and feet with very small and sometimes questionable lesions (possible erosions and cysts) were scored independently two times by four investigators. The percentage of lesions found in exactly the same position for each investigator was calculated. Intra-observer agreement between first and second reading in film-screen radiography was 64-76 % (mean 67 %), and in digital radiographs 60-71 % (mean 64 %). Agreement between film-screen and digital radiographs ranged from 54 to 64 % (mean 58 %) in the first reading and from 56 to 66 % (mean 62 %) in the second reading. Overall agreement between both techniques between first and second reading ranged between 62 and 73 % (mean 65 %). Digital radiography of the hands and feet can be used in patients suspected of rheumatoid arthritis and in follow-up of those patients, because small and early erosions can be seen equally well with the digital technique as compared with the conventional film-screen technique. | |
10606386 | Bone non-union after osteotomy in patients treated with methotrexate. | 1999 Dec | We describe 2 men with seronegative rheumatoid arthritis who presented non-union of bone after osteotomy of the tibia in one case and of a metatarsal bone in the second. Both patients were still being treated with oral low doses of methotrexate (MTX). After MTX was stopped, a prompt healing of the bone occurred. These observations suggest that MTX should be stopped temporarily in cases with delayed bone healing after surgery. | |
9295452 | Illness behavior in rheumatoid arthritis. | 1997 Aug | OBJECTIVE: To explore prediagnostic illness behavior in rheumatoid arthritis (RA). METHOD: In this descriptive study, interview and medical records data from 50 female patients were analyzed using quantitative and qualitative techniques. RESULTS: Findings revealed a high incidence of symptom normalization, self-treatment, symptom comparison, and prolonged time to diagnosis with multiple misdiagnoses and physicians consulted. Most subjects reported invalidation of initial symptoms, multifaceted emotional distress, and relief upon accurate diagnosis. Significant associations were found between (a) illness-related symptom attributions and fewer physicians consulted (P < 0.05) and less invalidation (P < 0.05); (b) life stress events and fewer physicians consulted (P < 0.05) and shorter time to diagnosis (P < 0.05); (c) remissions and time to diagnosis (P < 0.05), number of physicians consulted (P < 0.001), and number of misdiagnoses (P < 0.001). CONCLUSION: Illness behavior in RA is prolonged, convoluted, and accompanied by personal and social stress. Invalidation of reported symptoms and relief upon definitive diagnosis are prominent features of the process. | |
9785392 | Cross-sectional epidemiological survey of rheumatoid arthritis patients seen in private pr | 1998 Jul | OBJECTIVE: To conduct an epidemiological study of rheumatoid arthritis patients seen by office-based rheumatologists in France (first semester of 1996). METHODS: Cross-sectional study of 1629 rheumatoid arthritis patients conducted by 373 office-based rheumatologists who volunteered for the study (one visit per patient). Each rheumatologist was to complete a 200-variable questionnaire for the first four rheumatoid arthritis patients who came to their office. RESULTS: Women contributed 81% of the sample (mean age, 57 years); 19% of patients were seen in the Paris area, 20% in the North East, 20% in the North West, 22% in the South East and 19% in the South West. Twenty-nine per cent of patients had a paid job and 21.1% (all women) were homemakers. Among the patients with a paid job, 44% were on sick leave, with the reason for the sick leave being the rheumatoid arthritis in 36% of cases. Nineteen per cent of patients had stopped working permanently because of their rheumatoid arthritis, after a mean disease duration of six years. Mean disease duration in the overall sample was eight years. The diagnosis was established within six months of symptom onset in 75% of cases. A family history of rheumatoid arthritis was found in 11% of patients and a family history of other autoimmune diseases in 2%. The disease was precipitated by a stressful life event in 17% of cases. Follow-up was being provided only by the study rheumatologist in 59% of cases and also by a general practitioner in 39%. The disease was quiescent in 9% of cases, minimally active in 32%, moderately active in 46% and severely active in 13%. Eighty-four per cent of patients were on one (78%) or more (6%) second-line drugs including methotrexate (45%), an antimalarial (17%), intramuscular gold (14%), tiopronin (9%), D-penicillamine (6%) and sulfasalazine (12%). Fifty-two per cent of patients were on steroid therapy (mean dose, 7.5 +/- 5.7 mg/d). Other drugs included nonsteroidal antiinflammatory agents (61%), analgesics (61%), gastroduodenal protective agents (45%) and anxiety-relieving agents (10%). Twenty-four per cent of patients had had one or more surgical procedures (mean, 3/patient) for their joint disease. CONCLUSION: This nation-wide epidemiological survey conducted in France provides a database on the socioeconomic and demographic characteristics of rheumatoid arthritis patients followed in private practice. | |
10434573 | [Effects of a low calorie vegan diet on disease activity and general conditions in patient | 1999 Jun | There is little objective information about diet therapy for rheumatoid arthritis (RA) in Japan. We studied 14 patients with RA who stayed in the Koda hospital for 55 days. They basically took a 1200 kcal vegan diet consisting of unpolished rice gruel, juice of raw vegetables, soya bean curd and sesame seeds, and undertook a 3-5-day fast three times. During the 55-day stay, average body weight decreased by 5.1kg. Lansbury index and ESR decreased whereas CRP did not change. WBC decreased and the differential cell counts showed a decrease of neutrophils, eosinophils and monocytes without a change in lymphocytes or basophils. RBC, hemoglobin and MCV increased. LDL-C decreased, while HDL-C increased. There was no change in total protein or albumin. These data suggest that this combination of a low calorie vegan diet and fasting may contribute to improve RA with little undesirable effects on the patient's general conditions. | |
11478050 | Surgical treatment of the rheumatoid thumb. | 2001 May | Rheumatoid arthritis commonly affects the thumb. Deformity does not require surgical intervention unless pain is present or a functional deficit exists, but if bony erosion develops and surgical treatment may be compromised in the future, earlier intervention may be indicated. When the pathogenesis and pathoanatomy of the impaired rheumatoid thumb are appreciated, and appropriate treatment is selected, surgical intervention is likely to provide a favorable outcome for the patient. | |
10941803 | The predictive value of attributes of pain to classify rheumatoid arthritis. | 2000 | Out of 2300 patients with rheumatic diseases 1627 were analysed to develop a classification of rheumatoid arthritis based on clinical attributes of pain. Of these, 641 patients had the disease and 986 were controls with other rheumatic conditions. For traditional format classification, six of eight variables were selected: pain at a fixed joint; symmetrical pain; continuous pain; pain mainly present at night or in the morning; pain following joint pressure; and pain decreased by load/movement. The occurrence of four or more of these features was associated with a 72.1% sensitivity and a 79.1% specificity. A classification tree constructed on four features that showed the greatest diagnostic power (symmetrical pain, pain mainly present at night or in the morning, pain at joint pressure, continuous pain), was associated with a 75.8% sensitivity and a 77.0% specificity. | |
11196668 | Association of the TNF +489 polymorphism with susceptibility and radiographic damage in rh | 1999 Nov | Multiple genetic factors contribute to susceptibility to rheumatoid arthritis (RA). The extent of variability in disease presentation in RA may be related to genetic heterogeneity. In this study we investigated the association of the TNF gene polymorphism at position +489 with susceptibility to and severity of RA. Analysis of the frequency of the +489 A and G alleles in a group of 293 consecutive RA patients and 138 healthy controls revealed a significant decrease of the A allele. The +489 GA patients had a 3.9 times decreased chance of having erosive disease than +489 GG patients. These results were confirmed in a prospective study using a cohort of 112 patients who were followed for 12 years. The progression rate of the erosion score over 12 years expressed as Sharp score for X-rays of hands and feet was 3.4 per year for the GA-genotyped patients and 12.1 for the GG-genotyped patients. These associations were independent of rheumatoid factor and HLA-shared epitope positivity. In conclusion, these data suggest that the intron TNF +489 polymorphism is associated with susceptibility to and disease severity of RA independently of HLA-shared epitope-positive alleles. | |
11028847 | MRI of cervical spine with flexion and extension used in patients with rheumatoid arthriti | 2000 | Patients with rheumatoid arthritis (RA) often have involvement of the cervical spine. The most common abnormality is atlanto-axial subluxation (AAS). The more serious vertical subluxation (VS) is thought to develop at a later stage. Direct cord compression may occur, but the symptoms may be vague and difficult to interpret. In addition to clinical follow up, RA patients undergo several conventional radiographs of the cervical spine, with addition of flexion and extension images. This, in spite of the fact that the cervical cord and soft tissue do not show. Magnetic resonance imaging (MRI), is the modality of choice to visualize soft tissue and the cervical medulla, but is rarely performed in the follow up of RA patients. Five patients with long-standing RA, episodes of neck pain, and known AAS were asked to volunteer for a MRI study of the cervical spine, consisting of sagittal T2 weighted images of the cervical spine during flexion and extension of the neck. Compared to clinical examinations and cervical radiographs, MRI gave valuable information not otherwise obtained. The importance of MRI with the neck in a flexed and extended position is stressed. This is possible to obtain within a conventional quadrature neck coil in many RA patients. | |
11355217 | Rheumatological symptoms. Will investigation make a difference? | 2001 Apr | BACKGROUND: Many tests are available for investigation and monitoring of rheumatological symptoms, but their usefulness depends on appropriate choice and correct interpretation of the result. OBJECTIVE: To discuss which investigations are appropriate in assessing a variety of rheumatological symptoms and how to interpret results. DISCUSSION: Few of the tests used in the investigation of musculoskeletal symptoms are 'diagnostic'. False positives and false negatives often occur. It is important to interpret the test in the context of the individual patient. Monitoring of diseases is usually based on clinical findings, with investigations only used if they reliably parallel disease activity, monitor drug toxicity, or where changes in the test are likely to lead to modification of management. | |
9224234 | Rheumatologic view of the rheumatoid foot. | 1997 Jul | Rheumatoid arthritis is a common systemic disease that affects between 0.3% and 1.5% of the general population worldwide. In 1988, it was estimated by the National Arthritis Foundation that there were 4 to 6 million cases of rheumatoid arthritis in the United States. There is general agreement that the feet are a major source of pain and disability at some point in the course of the illness. The frequency of involvement of the feet among 1000 patients with rheumatoid arthritis studied by Vainio was 91% in females and 85% in males. The clinical features and pathogenesis of the rheumatoid foot and an approach to initial nonsurgical treatment will be discussed. | |
10609072 | Possible association of CYP17 gene polymorphisms with the onset of rheumatoid arthritis. | 1999 Nov | OBJECTIVE: The etiologic role of sex hormones in rheumatoid arthritis (RA) has been discussed. Cytochrome P450c 17 alpha (CYP17) regulates steroidogenesis and the restriction fragment length polymorphisms (RFLPs) of the CYP17 gene are related to serum sex hormone production. In this study, the relationship between CYP17 gene RFLPs and RA was investigated. METHODS: Genomic DNA was extracted from the peripheral blood of 91 male and 285 female patients with RA, as well as from 380 male and 579 female controls, and the RFLPs of the CYP17 gene (denoted as the A1 and A2 alleles) were determined. Clinical variables were recorded for the RA patients. RESULTS: There were no significant differences in CYP17 genotype distribution between the male RA patients and male controls, nor between the female RA patients and female controls. RA patients with the A2 allele tended to develop the disease at a younger age than those without (in men 50.1 vs 54.7 yrs, p = 0.15; in women 43.9 vs 47.4 yrs, p = 0.038). In women, having the A2 allele was a weak protective factor against developing RA at an older age (odds ratio: 0.63, 95% confidence interval: 0.41-0.95, p = 0.026). CONCLUSION: The RFLPs of the CYP17 gene may constitute a disease modifying factor through sex hormone production. | |
9101512 | Recovery of erosive rheumatoid arthritis after human immunodeficiency virus-1 infection an | 1997 Apr | The effects of human immunodeficiency virus type-1 (HIV-1) infection on rheumatoid arthritis (RA) are a matter of debate as there is no agreement on the influence of HIV-1 related immunodeficiency on this disease. We describe a patient with RA with symmetric joint erosions and positive rheumatoid factor (RF) who developed classic acquired immunodeficiency syndrome (AIDS) followed by left hemiplegia. RA improved with resolution of bony erosions and disappearance of RF, and reached complete clinical remission only in the paralytic limbs. Our observation suggests that, although essential, cell mediated immune response is not the sole mechanism involved in RA pathogenesis. Other factors such as the nervous system may play an important role. | |
9266128 | Joint destruction in rheumatoid arthritis: biological bases. | 1997 May | The pathogenesis of rheumatoid arthritis (RA) can be explained through two main hypotheses: macrophage-fibroblast and macrophage-T cell interactions. The interplay between the various populations is influenced by a strong genetic component, which determines the severity of the disease in some cohorts of patients attending referral centers. The key question of the nature of the antigen(s) driving joint inflammation still remains unsolved. Exogenous antigens such as viruses or bacteria have long been searched for in the synovial fluids as well as in tissues, but convincing evidence of their pathogenic role are lacking. Data have been accumulated on the possible role of autoantigens, such as the spliceosomes, filaggrin, calpastatin, type II collagens, or other endogenous peptides, but no definite role regarding their potential contribution to the activation of T cells has been established. Once the process starts, a progressive recruitment of inflammatory T cells and macrophages into the joints occurs through a complex series of adhesion and migratory events. The key driving steps leading to synovial inflammation and cartilage destruction, along with the potential contribution of some key molecules, have been described, thus opening possible perspectives for a therapeutic approach. | |
9543752 | [Sore throat in rheumatoid arthritis: 2 patients with cricoarytenoid arthritis]. | 1997 Aug 9 | In two patients with chronic rheumatoid arthritis, a woman aged 65 and a man aged 56 years, cricoarytenoid arthritis was diagnosed. The symptoms were hoarseness, sore throat and stridor. In both patients a narrowed glottic fissure was found. In one patient tracheostomy was necessary to guarantee a free airway; in the other, therapy with local corticosteroid injections (triamcinolone), combined with immunosuppressive therapy (prednisone), was effective. Early detection through anamnesis and laryngoscopy allows early therapy with a good prognosis. | |
10546603 | Total knee arthroplasty with posterior cruciate retention in patients with rheumatoid arth | 1999 Oct | The objective of the present study was to evaluate posterior cruciate ligament retention in total knee arthroplasty for patients with rheumatoid arthritis to determine long term ligamentuous stability. The study concerns an average 11-year followup (range, 10-13 years) of 52 patients (81 knees) with rheumatoid arthritis who had a total knee arthroplasty using a contemporary posterior cruciate retaining prosthesis. Particular attention was given to component survivorship and clinical stability. Fourteen patients (20 knees) died; none of these patients required revision surgery. No patients were lost to followup. Sixty-one knees in 38 patients were examined. In this group, the Knee Society knee score averaged 95 points (range, 63-100 points) and function score averaged 74 points (range, 0-100 points). Postoperative flexion averaged 112 degrees and extension averaged 0 degree. Four knees had 3 degrees asymptomatic hyperextension; one knee with 5 degrees hyperextension occasionally gave way. Five well aligned knees had between 6 degrees and 9 degrees varus or valgus laxity in extension, but no patient reported subjective instability. Two patients underwent revision surgery. One patient had a worn metal backed patella component replaced and the other patient had an open synovectomy for recurrent active rheumatoid synovitis. Thirteen-year survivorship based on need for revision surgery was 97% with the 95% confidence limits between 88% and 100%. There was no radiographic loosening or subsidence of prosthetic components. At 11-year followup, patients with rheumatoid arthritis whose knees were replaced with posterior cruciate retention prostheses experienced results equivalent to or better than those reported for patients with osteoarthritis at a similar followup. Late hyperextension and subsequent instability may be a concern in the second decade of followup. | |
9733445 | Osteonecrosis in the rheumatoid femoral head. | 1998 Sep | OBJECTIVE: To define the prevalence and pathological spectrum of femoral head osteonecrosis in patients with rheumatoid arthritis (RA) and to correlate its presence with disease related clinical and therapeutic factors. METHODS: A total of 545 primary total hip arthroplasties performed in 507 patients with RA were identified. A historical review of each patient's rheumatoid disease and treatment as well as pathological review of each femoral head specimen was performed. RESULTS: Osteonecrosis was identified in 66 specimens (12.1%) in one of 2 discrete forms. Thirty-two specimens (5.9%) contained classic subchondral avascular necrosis. Thirty-four specimens (6.2%) contained osteonecrosis in association with degenerative changes (within regions of sclerotic and eburnated subchondral bone), but not classic avascular necrosis. Remaining femoral head specimens were characterized by inflammatory arthritis (431 specimens) or degenerative joint disease (48 specimens). Corticosteroid therapy was used in 81% of patients with avascular necrosis and 68% with degenerative osteonecrosis. This was significantly greater prevalence than in patients without osteonecrosis (33%). Average daily prednisone dosage was 8 mg and no association between dosage and the presence of osteonecrosis was identified. No correlation between pathological findings and clinical disease severity was identified. In 5 of 27 specimens showing classic avascular necrosis and 11 of 34 containing degenerative osteonecrosis, no steroid treatment had been administered. CONCLUSION: Femoral head osteonecrosis is present in about 12% of patients with RA at hip arthroplasty, and occurs in 2 forms -- classic avascular necrosis and degenerative necrosis. Both forms are significantly associated with corticosteroid use. "Low dose" therapy does not protect patients against the development of osteonecrosis. Additionally, baseline prevalence of osteonecrosis of about 3% occurs in the absence of steroid use and may be related to the underlying inflammatory diseases. Despite its association with osteonecrosis the net effect of corticosteroid therapy on the natural history of rheumatoid hip disease remains unclear. | |
9704646 | Rheumatoid arthritis in the Pima Indians: the intersection of epidemiologic, demographic, | 1998 Aug | OBJECTIVE: To describe the clinical features and familial distribution of rheumatoid arthritis (RA) in the Pima Indians. METHODS: From 1965 through 1990, all cases of RA as defined by the American College of Rheumatology (formerly, the American Rheumatism Association) 1987 criteria or all cases of seropositive, erosive disease as defined by the Rome criteria were identified in individuals who were age 20 years and older and were of 50% or more Pima/Tohono-O'odham heritage. Radiographs were reviewed by 2 musculoskeletal radiologists who were blinded to case status. Kinship coefficients were used to evaluate familial aggregation. RESULTS: Eighty-eight RA cases were identified from this population-based sample. Over 66% of the cases had seropositive disease, over 60% had erosive disease, and over 40% had subcutaneous nodules. Of the 88 RA cases, 40 were members of families with more than 1 RA case. The remainder were simplex cases. CONCLUSION: In this population, clinical markers of severe RA were present in a majority of cases. The presence of familial aggregation for RA in the Pima Indians suggests underlying genetic factors in disease pathogenesis. | |
9840493 | Oculomotor dysfunction in rheumatoid patients with upper cervical dislocation. | 1998 Sep | Several studies of patients with chronic cervical pain and chronic whiplash syndrome report a high frequency of oculomotor function derangements pointing towards brainstem involvement and/or default sensory input from neck afferents. In light of these reports, it seems important to investigate other patient groups with similar upper cervical spine disorders. In this study, voluntary eye motor performance was evaluated in 11 rheumatoid patients (RA) with upper cervical dislocation and a clearly noticed joint affection of the cervical spine. The results were compared with 6 RA patients without cervical engagement and normal individuals. Nine of the 11 patients with atlanto-axial dislocation showed pronounced oculomotor disturbances of smooth pursuits compared with only minor changes in the control group. The pattern of oculomotor dysfunction in patients with rheumatoid cervical dislocation indicates brainstem involvement, which may be an early sign of brainstem affection/myelopathy. | |
11093435 | The effect of HLA-DRB1 genes, rheumatoid factor, and treatment on radiographic disease pro | 2000 Nov | OBJECTIVE: To investigate the relationship between radiographic disease progression in the presence or absence of rheumatoid arthritis (RA) linked HLA-DRB1 alleles after early introduction of disease modifying antirheumatic drug therapy in patients with RA over a study period of 6 years. METHODS: One hundred nine patients of a trial comparing intramuscular (im) gold sodium thiomalate (GSTM) and im methotrexate (MTX) in early erosive RA were followed for 6 years with regular assessments of clinical and laboratory data and yearly radiographs of hands and feet, and they were typed for HLA-DRB1 genes. Radiographic progression was analyzed for an influence of rheumatoid factor (RF) status and HLA-DRB1 genes. RESULTS: Twenty-seven patients (25%) were positive for two, 46 (42%) for one, and 36 (33%) for none of the disease linked alleles. A decrease of the rate of radiographic disease progression with treatment in this group of patients was reflected by the decline in the slope of the radiographic score. Seropositive patients (n = 71, 68%) had a significantly more destructive disease course than RF negative patients. In seropositive disease, patients with a "double dose" of RA linked alleles showed a tendency to greater progression during the first 12-24 mo of treatment, but no significant difference in the longterm radiographic outcome could be detected between subgroups defined by the presence or absence of HLA-DRB1 genes. There was no significant difference throughout the study period with respect to the clinical disease course as assessed by joint swelling, C-reactive protein, and erythrocyte sedimentation rate. The majority of the seronegative population (n = 38, 32%) had a benign disease course with the exception of patients (n = 6) with the double allele; they had radiographic disease progression comparable with the seropositive patients. CONCLUSION: Our data do not provide evidence for a more aggressive disease course in patients bearing double RA linked HLA-DRB1 alleles. |
