OBJECTIVE: To determine clinical variables useful in predicting the prognosis of patients with early rheumatoid arthritis (RA) by investigating the relationship between clinical variables and radiological progression. METHODS: One hundred eighteen patients with early RA whose symptoms developed within the previous year were enrolled in a prospective study. Data from the 98 patients who completed the 2 year study were analyzed, using the number of erosive joints and Larsen's score as the outcome of RA. RESULTS: Increases in the number of erosive joints at 12 months after entry into the study were significantly correlated with the number of swollen joints (r = 0.510), erythrocyte sedimentation rate (ESR) (r = 0.404), and C-reactive protein (CRP) (r = 0.487) at 6 months. The same results were seen using Larsen's score as the measure of outcome. The average number of erosive joints or mean Larsen's score at 12 months was higher in patients whose levels of CRP were high at 6 months and suppressed by 12 months, but increased much less in patients whose levels of CRP were successfully suppressed by 6 months. More joint erosions were noted in patients with positive rheumatoid factor (RF) than in RF negative patients. CONCLUSION: Joint erosions appeared with a certain time lag after active synovitis. Earlier introduction of effective treatment is recommended for the prevention of RA joint damage. The presence of RF, number of swollen joints, ESR, and levels of CRP at 6 months after starting therapy are the most useful variables to predict radiological progression in patients with early RA. 相似文献

OBJECTIVE: Retroviruses can cause immunoregulatory disturbances and may play a role in the pathogenesis of autoimmune disorders. Little is known about the frequency of behavioral risk factors for exogenous retroviral infections in patients with autoimmune diseases. We compare the frequency of recognized risk factors for retroviral infections among patients with systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and controls. METHODS: Patients with SLE and RA from a university rheumatology clinic and control patients were enrolled in this study. The presence of retroviral risk factors (intravenous drug use, prostitution, increased number of sex partners, sexually transmitted diseases, high risk sex partners, blood transfusion) was determined by a self-administered questionnaire. RESULTS: We surveyed 81 patients with SLE and 117 with RA and 100 healthy controls. Patients in all groups reported similar exposure to all risk factors surveyed for retroviral infection except sexually transmitted disease, which was reported more often in patients with SLE (25% of SLE versus 11% of RA and 11% of controls, p = 0.013). CONCLUSION: Self-reported retroviral risk factors were generally not increased in patients with autoimmune disease compared to healthy controls; the role of exogenous retroviruses in the pathogenesis of SLE and RA remains unclear. 相似文献

OBJECTIVE: To describe the longitudinal radiographic course of rheumatoid arthritis (RA), and to identify and quantitate predictors of radiographic progression. METHODS: This prospective, longitudinal study of radiographic progression and clinical predictors of RA involved 256 patients with RA who were seen within the first 2 years of disease (mean 0.77 years) and were followed up for up to 19 years. Participants underwent a total of 6,278 clinical assessments (mean 24.5) and 934 paired radiographs (mean 3.1, range 2-6). Clinical assessments at every visit included determination of the erythrocyte sedimentation rate (ESR), grip strength, pain scores, tender joint counts, and anxiety and depression measurements. Regression analyses utilized time-integrated predictors. RESULTS: Overall, radiographic progression rates, as measured by the summary Sharp scores, appeared constant over the course of RA. The strongest correlate of progression was the time-integrated ESR (rho=0.53). This association grew stronger with time. At 0-5 years, 5-10 years, 10-15 years, and 15-20 years, correlations were 0.40, 0.50, 0.65, and 0.74, respectively, and for the period 10-20 years, the correlation was 0.67. In multivariate models, the mean ESR, mean grip strength, rheumatoid factor positivity, and tender joint count were independent predictors of radiographic progression. CONCLUSION: Radiographic damage occurs at a constant rate in RA, and is not greater early in RA or reduced later in the course of the illness. Acute-phase reactants are, by far, the strongest determinants of progression. 相似文献

OBJECTIVE: Pain in the joints and other areas has been a frequent complaint among veterans of Operation Desert Storm who are experiencing unexplained illness. We characterized the rheumatic manifestations of a group of veterans of the Persian Gulf War who were referred to a rheumatology clinic. METHODS: Consecutive South Texas veterans of the Persian Gulf War who were referred for evaluation of rheumatic manifestations underwent a comprehensive evaluation of their musculoskeletal symptoms, pain, and health related quality of life. RESULTS: Of 928 veterans evaluated in a screening clinic for unexplained symptoms, 145 had rheumatic manifestations (15.6%) and were referred to a rheumatology clinic. The most common diagnosis was fibromyalgia, present in 49 patients (33.8%), followed by various soft tissue problems in 25 (17.2%), nonspecific arthralgias in 14 (9.6%), and clinical or radiographic osteoarthritis in 16 (11.0%). In 39 patients (26.9%), no symptoms were present at the time of the evaluation, a careful musculoskeletal examination and laboratory tests were normal, and no diagnosis was possible. Two patients had Reiter's syndrome. Four had a positive rheumatoid factor and 3 had antinuclear antibodies, but none of these had clinical evidence of rheumatoid arthritis or systemic lupus erythematosus. Pain was present in nearly all patients and was widely distributed, with no body area spared in this group of patients. The most frequent painful areas were the knees in > 65%, the lower back in > 60%, the shoulders in 50%, and the hands and wrists in 35%. Widespread body pain was present in 65.1% of the veterans. Average values of all 8 scales measured by the SF-36 health survey were below the 25th percentile of published national norms, with pain and the number of nonarticular rheumatic symptoms explaining most of the decreased health related quality of life in the veterans we evaluated. CONCLUSION: No specific rheumatic diagnosis is characteristic of Gulf War veterans with unexplained illness referred to a rheumatology clinic. However, pain is common and widespread in these patients, and their health related quality of life is poor. Further research is necessary to determine the cause of the symptoms of veterans of the Gulf War. 相似文献

OBJECTIVE: To investigate the clinical course in early rheumatoid arthritis (RA) patients followed prospectively, to relate course to outcome after 5 yr, and to try to identify prognostic features. METHODS: A total of 183 patients with definite RA and a mean disease duration of 11 months were included. Of these, 75% were rheumatoid factor (RF) positive; 85% carried the shared epitope, 32% on both alleles. Most patients were assessed every 6 months. Disability was evaluated with the Health Assessment Questionnaire (HAQ) and radiographic findings according to Larsen. Remission was defined in two ways: with the American Rheumatism Association (ARA) criteria and as 'no arthritis at least at one follow-up visit'. RESULTS: Twenty per cent achieved ARA-defined remission periods of at least 6 months duration; 21 were spontaneous and 18 drug induced. Average length of remission was 20.5 months. The remission periods constituted 7% of follow-up for all patients. Another 36% achieved remission according to the second definition. All 56% were considered to have a relapsing-remitting disease pattern, in contrast to the remaining 44% with a persistent disease pattern. More patients with persistent disease were treated with disease-modifying anti-rheumatic drugs (DMARDs) and had also received a larger number of different drugs. Outcome after 5 yr regarding disability, joint inflammation and joint damage was worse for patients with persistent disease. Neither ARA-defined remission nor disease pattern could be accurately predicted. CONCLUSIONS: Long-term ARA-defined remission was rare, constituting 7% of follow-up for the entire cohort. For those 20% achieving remission, this period represented 34% of their follow-up. A total of 56% had a relapsing-remitting disease pattern and 44% had a persistent disease pattern. This classification had prognostic implications with persistency being a bad prognostic sign. 相似文献

It has been well known that DMARDs are very effective for rheumatoid arthritis but lose their effect after long term administration. The authors would expect that Lobenzarit disodium (CCA) could slow the reduction of effectiveness of the DMARDs. The aim of this paper is to clarify the effects of Lobenzarit disodium (CCA) for the rheumatoid patients maintained by sodium aurothiomalate and D-penicillamine. The classical and definite rheumatoid patients were divided into two groups. One (group-A) was the rheumatoid patients who were treated in combination with CCA (79 patients). Another (group-B) was rheumatoid patients who were treated by sodium aurothiomalate or D-penicillamine (78 patients). All of them were followed for four years. In group-A, Lansbury index didn't improve in comparison with group-B. However, in the parameters of Lansbury index, improvement of the swelling joints was clearly higher in group-A than in group-B. Furthermore, this effect started in three months after administration of CCA and continued until the end of this study. On the other hand, according to roentogenographic examination utilizing MD's method, density of the metacarpal bones decreased more in group-B than in group-A. The sid-effects were few. They were five cases of gastrointestinal disorders and three cases of renal dysfunction. However, the renal dysfunction seems unlikely to be causally related to CCA. The authors could confirm the certain and expected results of combination therapy with CCA and sodium aurothiomalate and D-penicillamine for the rheumatoid patients. 相似文献

OBJECTIVE: To evaluate the effect of early 'aggressive' drug treatment on radiographic progression in patients with recent-onset rheumatoid arthritis (RA), compared to conventional stepwise increasing intensity of treatment. DESIGN: Prospective follow-up study with an experimental group and a historical control group both divided into a high-risk subgroup and a low-risk subgroup, based on prognostic factors. The effect of the 'aggressive' and the conventional treatment strategy was compared between both high-risk groups; the low-risk groups, both treated according to the conventional treatment strategy, were used to ensure internal consistency between the experimental and the historical groups. PATIENTS: A total of 228 consecutive patients with recent-onset RA (complaints < 1 yr at study entry). METHODS: The 'aggressive' drug treatment consisted of institution of relatively fast-acting disease-modifying anti-rheumatic drugs (DMARDs) (sulphasalazine, methotrexate) immediately after diagnosis, and rapid adjustment of dosage and/or drug in the case of insufficient response as measured by a change in C-reactive protein (CRP) level. Radiographic damage was assessed according to a modified version of Sharp's method and cumulative disease activity expressed as CRP-area under the curve (CRP-AUC). The occurrence of side-effects was also evaluated. RESULTS: After 2 yr of follow-up, comparison of the two high-risk subgroups showed the radiographic progression in the 'aggressively' treated subgroup to be significantly lower than that in the control group [Sharp score: median (range) 26 (0-100) vs 35 (1-188); P = 0.03]. Cumulative CRP values were also significantly lower than in the control high-risk subgroup [CRP-AUC: median (range) 1963 (212-8515) vs 3025 (46-15 632) mg.week/1; P = 0.002). This was achieved without an increase in the occurrence of side-effects. There was no difference between the two low-risk subgroups with regard to entry characteristics, CRP-AUC values or radiological progression, indicating comparability between the two groups. CONCLUSION: Early 'aggressive' drug treatment, using sulphasalazine and/or methotrexate, aimed at reduction of the CRP level, significantly reduces the (rate of) radiographic progression in RA. 相似文献

PURPOSE: To examine rheumatology subspecialty practice patterns, determinants of referral to rheumatologists, and utilization of aspiration and injection procedures in a population-based sample of elderly individuals. SUBJECTS AND METHODS: We obtained Medicare physician claims for all visits to rheumatologists among beneficiaries aged 65 years and older in Colorado, Massachusetts, and Virginia in 1993, and for visits to all providers by patients with coded diagnoses of rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). We examined variations in visit frequency and aspiration/injection procedures, and we analyzed determinants of referral to a rheumatologist for RA or SLE. RESULTS: In 1 year, 144,797 visits were made to rheumatologists by 38,443 patients in the three states. An inflammatory disorder was coded in 45% of visits and a noninflammatory disorder in 50%. Half of patients with RA were seen three or fewer times in the year. For RA and SLE, African Americans were about 60% as likely to be seen by a rheumatologist as whites. Utilization of rheumatologist services for rheumatoid arthritis and systemic lupus erythematosus was highest in the state (Virginia) with the lowest per capita supply of rheumatologists. Among patients with bursitis, tendinitis, and osteoarthritis, African-American women were more likely to receive an injection or aspiration procedure than whites or African-American men. CONCLUSION: Elderly patients with rheumatologic disorders were seen by specialists less frequently than recommended by a recent rheumatology manpower survey. African-Americans with RA and SLE had fewer rheumatology visits than whites. 相似文献

OBJECTIVE: To ascertain the prevalence of rheumatoid arthritis (RA) in an Italian general population. METHODS: The study was performed in the years 1991-92 in Chiavari, a small town located on the Ligurian coast, and involved 4456 subjects aged 16 years or more from four general practices. The subjects received a postal questionnaire developed to detect patients with current or past inflammatory joint diseases. The age and sex distribution of the sample were similar to those of the Italian population from the 1992 census. Patients reporting a history of joint swelling in at least a pair of symmetrical joints were reviewed by a rheumatologist. The clinical records of non-responders and responders who failed to attend the clinic were also reviewed. RESULTS: 3294 of 4456 (73.9%) subjects answered to the questionnaire. The mean (SD) age of the 3294 responders was 48.3 (19.3) years; 53.7% of them were female. Swelling in at least two symmetrical joints was reported by 230 subjects (7%). Among them, 11 patients fulfilling the 1987 ARA criteria for RA were identified. The prevalence of RA was 0.33% (95% CI 0.13, 0.53) in the general population, 0.13% (95% CI 0, 0.31) in men, and 0.51% (95% CI 0.18, 0.84) in women. CONCLUSIONS: These data are consistent with the results of three earlier studies published in the fifties in the Italian literature and confirm that the prevalence of RA is low in Italy and has remained unchanged in the last 40 years. 相似文献

To evaluate the usefulness of magnetic resonance imaging (MRI) enhanced with gadolinium-DTPA (Gd-DTPA) for the detection of the inflamed synovium and for the evaluation of the response to therapy in rheumatoid arthritis, we studied 49 patients with rheumatoid arthritis (RA) according to the 1987 revised criteria of American Rheumatism Association (ARA), 6 patients of systemic lupus erythematosus (SLE) complicated by arthritis, 3 patients of osteoarthritis (OA), 2 patients of Sj?gren syndrome, 2 patients of progressive systemic sclerosis and 10 healthy volunteers as an age matched control. The 49 patients with RA were divided into three groups: (1) early phase of RA, (2) non progressing RA and (3) slowly progressing RA, and the stage classification of plain X-ray film and enhancement pattern of MR images were classified into three groups. Synovial enhancement showed a linear, band-like or diffuse pattern. Almost all cases in early phase of RA group and non progressing RA group showed a linear pattern, a band-like pattern or even no enhancement, while slowly progressing group of stage II or higher showed the diffuse pattern of enhancement in all except 2 cases. Moreover, the linear pattern, the band-like pattern or even no contrast enhancement were seen in all except 1 stage I patient, whereas 26 out of 29 patients with stage II or higher change showed diffuse contrast enhancement. Furthermore, a comparison of MR images before and after administration of DMARDs in 10 patients showed that the improvement of clinical symptoms correlated fairly well with reduction of contrast enhancement.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

OBJECTIVE: To determine the diagnostic and prognostic test qualities of the enzyme linked immunosorbent assays (ELISA) for rheumatoid factor isotypes in rheumatoid arthritis (RA), and to compare them with the latex fixation test. METHODS: Rheumatoid factor tests were performed in 1988 consecutive new rheumatology outpatients within two months after their first visit to the outpatient clinic of the Department of Rheumatology of Leiden University hospital. The sensitivity, specificity, accuracy, and predictive values of the tests in discriminating RA from non-rheumatoid arthritis and erosive from non-erosive disease after two years of follow up were determined and presented as receiver operating characteristic curves and post-test probability curves. RESULTS: The sensitivity of the ELISA for IgG, IgA, and IgM rheumatoid factor for RA versus all controls at optimal cut off titres was 72%, 44%, and 69%, respectively; the specificity was 52%, 84%, and 86%. For the latex fixation test the sensitivity was 66% and the specificity 91%. The post-test probability of RA, at a clinical prevalence rate of 12%, given a positive test result in the ELISAs for IgG, IgA, and IgM rheumatoid factor and the latex fixation test, was 17%, 27%, 40%, and 49%, respectively; with negative test results the probability was 7%, 8%, 5%, and 5%, respectively. The specificity of all tests in discriminating erosive from non-erosive RA at two years was low: 41%, 44%, 47%, and 58% for the ELISAs for IgG, IgA, and IgM rheumatoid factor and the latex fixation test, respectively. CONCLUSION: The ELISAs for IgG and IgA rheumatoid factor are of no significance in diagnosing RA and in the prediction of erosive disease. The ELISA for IgM rheumatoid factor is a reasonable alternative for the latex fixation test when age and gender are taken in to consideration. The specificity of all rheumatoid factor tests in discriminating erosive from non-erosive RA is low. 相似文献

OBJECTIVE: To explore whether there are different disease patterns of rheumatoid arthritis (RA) in women and men. METHODS: We studied 55 male case patients and 110 female control patients who developed RA between 1970 and 1985 and who resided and received medical care in Olmsted County, Minnesota, for at least 10 years after the diagnosis of RA. Case and control patients were matched for the date of first diagnosis. The pattern and extent of joint involvement, the frequency of joint surgeries, and the presence and type of extraarticular manifestations were determined by retrospective chart review. RESULTS: Incidence rates in women were variable and age dependent, whereas the risk in men older than 36 years was constant over their lifetime. Erosive disease was more frequent in men than in women (72% versus 55%, respectively; P < 0.05) and tended to occur earlier (47% versus 31% for erosive disease within the first 4 years of RA). Although male sex was correlated with a higher risk of bony erosions and an accelerated course of RA, structural consequences of joint destruction were more pronounced in women. Joint surgery was performed more frequently in women (50%) than in men (27%) (P = 0.01). In particular, the frequencies of arthroplasties and arthrodeses of hand and foot joints were different (34 procedures in women versus 1 procedure in men; P < 0.001). Sex influenced the risk as well as the pattern of organ involvement in RA. Nodules and rheumatoid lung disease were typical manifestations in men (P = 0.001 and P < 0.001, respectively), whereas women typically developed sicca syndrome (P = 0.05). Despite differences in disease aggressiveness and disease pattern, there was little difference in the medical therapy in the men compared with the women. CONCLUSION: RA is a heterogeneous disease with variations in phenotype. Sex-associated factors influence disease severity as well as disease pattern. Because sex-related effects influence treatment goals, treatment responses, and side effects, they should be considered in clinical study design and analysis as well as in the treatment decisions for individual patients with RA. 相似文献

The eyes of 11 patients with rheumatoid arthritis (RA) who received extended chrysotherapy (mean cumulative dose greater than 7 grams during a mean 6-year period) were examined biomicroscopically. Minute reddish-purple particles were seen in the cornea (corneal chrysiasis) in 5 and in the lens (lens chrysiasis) in 4 patients. Particulate deposits were absent in 11 other RA patients who had not received gold treatment. Seven crystalline lenses from 5 gold-treated patients were removed surgically because of incidental cataract formation and analyzed for gold content using neutron activation analysis. Although the mean lens gold concentration was higher in these patients than in non-gold-treated controls without RA (0.0073 microgram/grams versus 0.001 microgram/grams), the absolute gold level was markedly lower than that found in 25 diverse tissue analyzed previously. This finding is compatible with the absence of clinical gold-related lens disease or visual impairment. 相似文献

OBJECTIVE: To compare the efficacy of hydroxychloroquine, penicillamine, sodium aurothiomalate and auranofin in the treatment of active rheumatoid arthritis over a period of 5 yr. METHOD: Five hundred and forty-one patients with definite or classical rheumatoid arthritis were entered into an open randomized controlled trial with a flexible dose regimen designed to reflect clinical practice. Decisions to stop treatment with any one of the disease-modifying anti-rheumatic drugs (DMARDs) were based on an agreed trial protocol which defined criteria for adverse reactions and therapeutic failure. The managing physicians' decisions were confirmed in a separate monitor clinic. RESULTS: The proportion of patients who remained on their first DMARD or who were in remission at 5 yr was 53% for penicillamine, 34% for sodium aurothiomalate, 31%, for auranofin and 30% for hydroxychloroquine (P < 0.001). In patients who stayed on their first DMARD, all groups showed a 30-50% improvement in C-reactive protein, erythrocyte sedimentation rate, Ritchie Index and joint stiffness, and a deterioration in their Larsen score. There was no evidence of physician bias to explain the larger proportion of patients remaining on penicillamine for 5 yr. CONCLUSION: Despite the increased popularity of sulphasalazine and inmmunosuppressives, the drugs in this study continue to be used worldwide. The natural history of rheumatoid arthritis requires long-term follow up to establish drug efficacy. Evidence is needed as to whether the newer regimens will prove to be more effective and safer in the longer term than the commonly prescribed DMARDs. The data from this trial will provide a reference for comparison with future studies. 相似文献

OBJECTIVE: To determine prognostic factors in rheumatoid arthritis (RA). METHODS: One hundred thirty-two women with definite RA were followed yearly from an early phase of the disease (symptoms < 5 years) for a mean duration of 6 years. The prognostic value of the first available clinical and laboratory variables and assessments of functional ability was related to several outcome measures (physician's opinion of disease severity, disease activity, radiological abnormalities, functional ability and number of prescribed 2nd-line drugs) by single predictor analysis and by logistic regression. RESULTS: The variables most predictive for one or more of the outcome measures were number of swollen joints, Ritchie score, health assessment questionnaire score, radiographical abnormalities, positive IgM rheumatoid factor (RF), positive IgG-RF, HLA-DR4, and an elevated percentage serum agalactosyl IgG. The accuracy of predicting outcome was calculated from several combinations of these variables, and varied between 70 and 80%. The accuracy based on a combination of the commonly available variables (number of swollen joints, IgM-RF and the erosion score), closely approximated the maximal accuracy that could be achieved. CONCLUSION: The outcome of RA can be predicted by a combination of variables that are commonly available in the clinical setting. 相似文献

OBJECTIVE: This study compared the progression of joint damage in patients with early active severe rheumatoid arthritis (RA) treated with cyclosporin or parenteral gold. METHODS: In this open, randomized, multicentre study with a blinded radiological endpoint, 375 patients who had suffered from active severe RA for <3 yr were randomized to be treated for 18 months with low-dose cyclosporin or parenteral gold. The groups were stratified with regard to corticosteroid use. Primary efficacy variables were numbers of erosions, erosion score and the Larsen-Dale joint damage score. RESULTS: Joint damage progressed at similar rates in both treatment arms. In both groups, patients receiving corticosteroids had less X-ray progression. Rheumatoid factor positivity, high swollen joint count, high erythrocyte sedimentation rate and pre-existing X-ray abnormalities predicted progression of joint damage. Although numbers of serious adverse events were similar, more gold patients (n = 65) than cyclosporin patients (n = 45) withdrew from study medication because of adverse events. CONCLUSION: Cyclosporin was comparable to parenteral gold in retarding progression of joint damage and was better tolerated in terms of adherence to therapy. The open label design should be kept in mind when assessing this difference. 相似文献

OBJECTIVES: Serious upper gastrointestinal events are an important threat to patients with arthritis who are treated with non-steroidal anti-inflammatory drugs (NSAIDs). In this study risk factors for serious upper gastrointestinal events are identified in patients with possible or definite rheumatoid arthritis (RA). METHODS: A retrospective analysis of factors that might contribute to the risk of serious upper gastrointestinal events was performed in a cohort of 2315 consecutive patients with possible or definite RA. The relative influences of disease severity, drug treatment, particularly with corticosteroids, and history of peptic ulceration were analysed with a conditional logistic regression model for the 106 patients with serious upper gastrointestinal intestinal events and for an equal number of control patients who were matched for age, gender, number of criteria for RA, and disease duration. RESULTS: The incidence rate for serious upper gastrointestinal events was 4.0/1000 patients in each year. The study reconfirmed that age over 60 years, history of peptic ulceration, and use of corticosteroids are risk factors. The presence of extra-articular manifestations of RA was associated with a two to 11-fold increase in the risk for serious upper gastrointestinal events. This risk was independent of the use of corticosteroids. CONCLUSION: Disease severity, in particular the presence of extra-articular features, may be an important factor in the pathogenesis of upper gastrointestinal ulceration in patients with RA who are treated with NSAIDs. 相似文献

OBJECTIVE: Rheumatoid arthritis (RA) may be biologically reversible if treated in the first several months, yet it is unknown whether patients are diagnosed that early. We investigated the lag time between symptom onset and diagnosis of RA in a population with excellent access to rheumatology care. METHODS: Using review of medical records, we evaluated all patients newly diagnosed as having RA from 1987 through 1990, at a health maintenance organization in central Massachusetts. Total lag time from symptom onset to first definite diagnosis was divided into medical encounter lag time (from symptom onset to first medical encounter) and diagnosis lag time (from first medical encounter to diagnosis). RESULTS: The median total lag time was 36 weeks (range 4 weeks to > 10 years). The median medical encounter lag time was 4 weeks (not all patients included in the analysis). The median diagnosis lag time was 18 weeks. Diagnosis lag time was shorter for patients with progressive disease and positive rheumatoid factor on the initial test. Of 25 patients with symmetric arthritis and positive rheumatoid factor, only 5 (20%) were diagnosed within 2 months, and 10 (40%) were diagnosed more than 6 months after symptom onset. CONCLUSION: RA diagnosis is usually delayed for several months after symptoms begin, in large part because of delay in diagnosis by the physician. Thus, the goal of initiating treatment extremely early may be unrealistic for most patients. 相似文献

The effects of physical training on elderly, fragile patients with rheumatoid arthritis (RA) who are on low-dose steroids were investigated. The controlled study included 24 patients who had been treated with low-dose steroids for 2 years. Each patient was assigned either to a treatment group receiving training or to an untrained control group. The training took place over a 3-month period and was based on a protocol using progressive interval training consisting of bicycle exercises, heel lifts, and step-climbing. The exercises were performed twice weekly for 45 minutes. Comparison of the two groups showed that disease activity did not increase in the trained group and that fewer, but not significantly fewer, swollen joints were observed in this group (p = 0.06). No significant changes were noticed in erythrocyte sedimentation rate, tender joints, or morning stiffness. The work capacity of the trained patients were doubled and the numbers of repetitions increased 76%. Individually adapted exercise programs can therefore be recommended for elderly rheumatoid arthritis patients on steroid treatment. 相似文献
