15517640 Efficacy of continuous passive motion following total knee arthroplasty: a metaanalysis. 2004 Nov OBJECTIVE: The objective of this metaanalysis is to examine the effectiveness of continuous passive motion (CPM) following total knee arthroplasty (TKA). METHODS: This metaanalysis used the methodology proposed by the Cochrane Collaboration. RESULTS: This review of 14 studies (952 patients) found significant improvements in active knee flexion and analgesic use 2 weeks postoperatively with the use of CPM and physiotherapy (PT) compared to PT alone. In addition, length of hospital stay and need for knee manipulations were significantly decreased in the CPM group. Not enough data were available to compare the degree of knee flexion applied or number of hours of application of CPM. However, significant results were not found for other comparisons such as short term CPM application versus longterm CPM application and wide treatment range versus small treatment range for the outcomes of active knee flexion, passive knee flexion and extension, presence of a fixed flexion deformity, use of analgesic, or total knee range of motion. CONCLUSION: CPM combined with PT may offer beneficial results for patients post-TKA. However, the potential benefits will need to be carefully weighed against the inconvenience and expense of CPM. More research is necessary to assess the differences in effectiveness with different characteristics of application such as total duration of treatment and intensity of CPM interventions.
14722206 Inhibition of leukotriene B4-induced CD11B/CD18 (Mac-1) expression by BIIL 284, a new long 2004 Feb BACKGROUND: Leukotriene B4 (LTB(4)) has a key role in the pathophysiology of rheumatoid arthritis (RA). OBJECTIVE: To investigate the inhibition of ex vivo LTB(4)-induced Mac-1 (CD11b/CD18) expression in leucocytes of patients with RA by the new oral LTB(4) receptor antagonist BIIL 284. METHODS: The pharmacokinetics and inhibition of LTB(4)-induced Mac-1 expression of BIIL 284 were characterised in 26 adult patients with RA who were treated with BIIL 284 25 mg, 150 mg, or placebo given once a day for 14 days according to a double blind, randomised, parallel group design. RESULTS: T(max) of BIIL 315 in plasma (main metabolite and active principle of BIIL 284 in plasma) was achieved about four hours after drug administration, and C(max,ss) and AUC(0-6h,ss) increased in proportion to the dosage. 100% inhibition of LTB(4)-induced MAC-1 expression was reached after two hours (150 mg) or four hours (25 mg), showing a statistically significant difference in comparison with placebo (p<0.005). A longlasting dynamic effect was seen consistently even when plasma concentrations declined to very low values 24 hours after administration. Secondary clinical efficacy end points remained unchanged probably owing to the short duration of treatment. Adverse events (AEs) were reported in 12 patients during the study. No serious AEs or laboratory AEs were seen. CONCLUSIONS: Both the 25 mg and 150 mg doses of BIIL 284 safely and effectively inhibit Mac-1 expression on neutrophils; thus longer treatment with BIIL 284 may result in clinical benefit for patients with RA.
12017848 [Ultrasound diagnosis in rheumatoid omarthritis]. 2002 Mar There are specific and unspecific signs of omarthritis. The more specific the signs seen together in connection with laboratory and clinical findings are, the more certain the result becomes. A complete scanning is necessary including axillary as well as static and dynamic examinations.
12229045 Targeted therapies for patients with rheumatoid arthritis. 2002 Aug Rheumatoid arthritis is characterised by an auto-immune response that eventually leads to the destruction of affected joints. This has major implications for patients' lives, with many becoming debilitated within three years of diagnosis. This paper describes the body's auto-immune mechanism and outlines new therapies that seek to block the body's destructive response to itself.
15237925 Proteome analysis reveals disease-associated marker proteins to differentiate RA patients 2004 New experimental approaches of molecular medicine such as transcriptome and proteome analysis have been implemented in rheumatology research. Two-dimensional gel electrophoresis in combination with mass spectrometry was used to visualize and to identify proteins in synovial fluid (SF) and plasma samples from patients with rheumatoid arthritis (RA) and osteoarthritis (OA). The small calcium binding protein S100A9 (MRP14) was identified as a discriminatory marker protein in SF by global proteomic analysis. To confirm these results and to examine the reproducibility and the applicability as a diagnostic marker, levels of the S100A8 (MRP8)/A9 (MRP14) heterocomplex in plasma and in synovial fluid were validated from patients with RA, OA, and other inflammatory joint diseases using enzyme immunoassay techniques. It was found that plasma levels of the S100A8/A9 heterocomplex correlate well with levels in SF, and hence, determination of plasma levels can be used to distinguish RA patients from patients with other inflammatory joint diseases, as well as from OA patients and controls. Initial studies on RA patients also indicate that plasma levels of the S100A8/A9 heterocomplex are a useful marker in monitoring anti TNFalpha therapy.
12087060 Anti-inflammatory cooperativity of corticosteroids and norepinephrine in rheumatoid arthri 2002 Jul Corticosteroids (CS) and norepinephrine (NE) support each other's biological effects. Thus, deficiency of cortisol and reduced synovial sympathetic innervation (SSI) may be proinflammatory in rheumatoid arthritis (RA). This study tested the anti-inflammatory cooperativity of CS and NE in human RA synovial tissue. In an in vivo study, 32 patients with RA (with prior CS therapy/without SSI: n=7; without prior CS therapy/with SSI: 6; with prior CS therapy/with SSI: 19) were investigated for synovial inflammation. In an in vitro study with synoviocytes from RA and OA patients, the separate and combined effects of cortisol and NE were studied. In the in vivo study, patients with prior CS therapy/with SSI showed lower secretion of synovial IL-8 than the other groups, lower synovial density of T cells and macrophages, and lower overall inflammation. In the in vitro study, a cooperative suppressive effect of NE (10(-6) M to 10(-8) M) and cortisol (10(-6) M and 10(-7) M) on secretion of IL-8 and TNF from primary early culture mixed RA synoviocytes was observed. This cooperative effect was not observed in OA synoviocytes. In the same RA and OA patients, the cooperative effect was lost in 3rd passage synovial fibroblasts. This study demonstrates the cooperativity of cortisol and NE for inhibition of proinflammatory mediators produced in the synovial tissue of RA patients. These results underscore that coupling of an efficient secretion of systemic cortisol together with local production of NE is important in order to lower synovial inflammation.
12784911 Adhesion molecules in gonarthrosis and knee prosthesis aseptic loosening follow-up: possib 2003 May The involvement of the synovium is common in phlogistic processes of various joint diseases. Apart from synoviocytes and the other cells in the synovial tissue, circulating cells recruited from peripheral blood also participate in the phlogistic process. The increased expression of adhesion molecules on both circulating and endothelial cell surface may further this recruitment. We studied 15 patients affected by serious gonarthrosis requiring a prosthetic implant (GPI) and 7 with knee prosthesis aseptic loosening (KPL) to evaluate adhesion molecule expression and phlogistic infiltration in the synovium using immunohistochemistry and microscopic analysis. As control we studied 10 subjects affected by degenerative meniscopathies undergoing a selective arthroscopic surgical meniscectomy. Analysis with Kruskal-Wallis test showed no statistical significant differences in the expression of CD54, CD11a, CD11b and CD18 in three groups examined. The model of variance analysis (Friedman test), showed that CD54 expression is greater in patients with GPI and KPL in comparison with the other molecules. Adhesion molecules and their functions are important in arthropathies not only because their evaluation can allow us to identify the degree of inflammation and to predict its evolution, but also because pharmacological control of their expression could have important therapeutic implications.
15082471 Chemokines in joint disease: the key to inflammation? 2004 Oct Targeting chemokines and/or chemokine receptors appears to be an intriguing new approach to treating chronic inflammatory disorders like rheumatoid arthritis, inflammatory bowel diseases, multiple sclerosis, and transplant rejections. The involvement of chemokines and chemokine receptors in inflammatory joint diseases, the in vitro and in vivo characteristics of the chemokine family in inflammatory joint disease, and initial clinical data on chemokine blockade in patients with rheumatoid arthritis suggest that targeting the chemokine and chemokine receptor family might provide a new, promising antirheumatic strategy.
15195775 Rheumatoid arthritis: more aggressive approach improves outlook. 2004 May As recently as 10 years ago, many patients with rheumatoid arthritis would receive only a nonsteroidal anti-inflammatory drug and low-dose corticosteroids until damage to their joints was documented. Now, despite risks of toxicity and adverse effects, a disease-modifying antirheumatic drug such as methotrexate is given as early as possible to retard disease progression and help prevent new erosions. Other agents can be added to or used in place of methotrexate, such as a biologic response modifier that regulates the proinflammatory cytokine tumor necrosis factor-alpha.
15593230 Use of mass spectrometry to identify protein biomarkers of disease severity in the synovia 2004 Dec OBJECTIVE: To identify a panel of candidate protein biomarkers of rheumatoid arthritis (RA) that can predict which patients will develop erosive, disabling disease. METHODS: A 2-step proteomic approach was used for biomarker discovery and verification. In the first step, 2-dimensional liquid chromatography-coupled tandem mass spectrometry was used to generate protein profiles of synovial fluid (SF) from patients with either erosive RA (n = 5) or nonerosive RA (n = 5). In the second step, the selected candidate markers were verified using quantitative multiple reaction monitoring mass spectrometry in sera of patients with erosive RA (n = 15) or nonerosive RA (n = 15) and of healthy controls (n = 15). RESULTS: Through differential profiling of proteins in the <40-kd portion of the SF proteome, we selected 33 prospective candidate biomarkers from a total of 418 identified proteins. Among the proteins that were elevated in the SF of patients with erosive RA were C-reactive protein (CRP) and 6 members of the S100 protein family of calcium-binding proteins. Significantly, levels of CRP, S100A8 (calgranulin A), S100A9 (calgranulin B), and S100A12 (calgranulin C) proteins were also elevated in the serum of patients with erosive disease compared with patients with nonerosive RA or healthy individuals. CONCLUSION: Several potential protein marker candidates have been identified for prognosis of the erosive form of RA. This study demonstrates the facility of using protein mass spectrometry in SF and serum for global discovery and verification of clinically relevant sets of disease biomarkers.
12847678 Polymorphism at position -308 of the tumor necrosis factor alpha gene influences outcome o 2003 Jul OBJECTIVE: To test whether the G-to-A polymorphism at position -308 in the promoter of the tumor necrosis factor alpha (TNFalpha) gene influences response to infliximab therapy in patients with rheumatoid arthritis (RA). METHODS: We genotyped 59 RA patients by polymerase chain reaction and subdivided them into two groups: those with the A/A or A/G genotype and those with the G/G genotype. We compared the groups' clinical responses to infliximab treatment after 22 weeks, using the Disease Activity Score in 28 joints (DAS28). RESULTS: We found that 42% of patients in the A/A and A/G group and 81% of patients in the G/G group had improvement of at least 1.2 in the DAS28 score (P = 0.0086). The average improvement in the DAS28 score was 1.24 in the A/A and A/G patients and 2.29 in the G/G patients (P = 0.029). CONCLUSION: These data suggest that patients with a TNFalpha -308G/G genotype are better infliximab responders than are patients with A/A or A/G genotypes. TNFalpha -308 genotyping may be a useful tool for predicting response to infliximab treatment.
11953968 Reshaping the shared epitope hypothesis: HLA-associated risk for rheumatoid arthritis is e 2002 Apr OBJECTIVE: To further analyze the association of HLA-DRB1 alleles with disease susceptibility in recent-onset rheumatoid arthritis (RA). METHODS: One hundred sixty-seven Caucasian RA patients and 166 healthy controls were typed for HLA-DRB1. RESULTS: The association of susceptibility to RA with the group of alleles encoding the shared epitope susceptibility sequences (SESSs) was confirmed in recent-onset RA. Among non-SESS alleles, DRB1*07, *1201, *1301, and *1501 showed significant protective effects. Even after correction for the influence of SESS alleles, significant independent protective effects of DRB1 alleles were observed. Protective alleles shared a third hypervariable region motif. Independent homozygosity effects were observed both for susceptibility and for protective alleles. CONCLUSION: Nonsusceptibility alleles differ significantly with regard to RA risk. Protective alleles show clear homology at positions 67-74, often encoding isoleucine at position 67 or aspartic acid at position 70. Susceptibility and protective alleles both show homozygosity effects. Based on these results and on data reported in the literature, in order to incorporate the finding of differential risks among nonsusceptibility alleles, we propose to reshape the shared epitope hypothesis as follows: HLA-associated risk for RA is encoded by amino acid substitutions at positions 67-74 of the HLA-DRB1 molecule.
15134615 Infectious and healing complications after elective orthopaedic foot and ankle surgery dur 2004 May BACKGROUND: Biologic response modifiers are assuming a larger role in the management of patients with rheumatoid arthritis. The tumor necrosis factor-alpha (TNF-alpha) inhibitors etanercept and infliximab improve patient symptoms and function. However, these agents have been associated with a risk for healing and infectious complications due to systemic blockade of TNF-alpha, a ubiquitous mediator required in the normal inflammatory response in tissue healing and infection surveillance. This study analyzed the risk of healing/infectious complications in patients undergoing elective foot and ankle surgery while being treated with TNF-alpha inhibitors etanercept and infliximab. METHODS: Patients with rheumatoid arthritis undergoing elective foot and ankle surgery over a 12-month period were prospectively followed for the development of complications in the postoperative period. All patients continued their antirheumatic medication schedule unaltered in the perioperative period. Data collected included sex, age, all medications used to treat rheumatoid arthritis, smoking history, and number of orthopaedic foot and ankle procedures performed. Patients were then stratified into two groups based on the use of immunomodulation via TNF-alpha inhibition (group 1) versus patients who did not receive TNF-alpha inhibition therapy (group 2). Groups 1 and 2 were followed and compared for the development of infectious/healing complications. RESULTS: Thirty-one patients were enrolled in the study. Group 1 (n = 16) and group 2 (n = 15) patients were comparable for sex distribution, number of orthopaedic procedures performed, and use of steroids, methotrexate, leflunamide, and nonsteroidal anti-inflammatory drugs. Group 1 contained six times the number of smokers in group 2. At mean follow-up of 10.6 months (group 1) and 9.7 months (group 2), healing or infectious complications were similar in both groups. However, when total complications (healing + infection) were analyzed, group 1 (TNF-alpha inhibition, "higher risk") patients demonstrated a lower complication rate (p =.033). CONCLUSIONS: The data suggest that in patients with rheumatoid arthritis undergoing elective foot and ankle surgery, the use of TNF-alpha inhibition agents may be safely undertaken in the perioperative period without increasing the risk of healing or infectious complications.
14566123 Fusion of the septic ankle: experience with 15 cases using hybrid external fixation. 2003 Oct BACKGROUND: In cases of septic joint destruction, an unfavorable situation of soft tissues and chronic osteomyelitis are responsible for high failure rates of ankle fusions. We wanted to evaluate the control of infection and the fusion rate using hybrid external fixators for the fusion of the septic ankle in a prospective study. METHODS: From 1996 to 1998, 15 arthrodeses were performed using hybrid external fixators. All patients had a combination of bone and soft tissue infections. Fourteen patients suffered from sequelae of posttraumatic osteoarthritis, and one patient suffered from rheumatoid arthritis. In 14 patients, pathogens could be identified; in 87%, Staphylococcus aureus was found. Eight patients had relevant concomitant diseases. RESULTS: The preservation of limbs by solid tibiotalar fusion was achieved in 14 patients (93%). One patient maintained an infected pseudarthrosis. During the 12-month follow-up, three patients had a fistula that persisted, with two patients having a solid arthrodesis. Full weight-bearing was possible for all the patients with a successful fusion. Seventy-five percent of the patients that had not retired at the time of the study regained their fitness for work. CONCLUSION: The hybrid external fixator presents a successful alternative for those arthrodeses of ankle joints where complications such as bone/joint infections or poor soft tissue conditions occur.
14996876 Copeland surface replacement arthroplasty of the shoulder in rheumatoid arthritis. 2004 Mar BACKGROUND: Shoulder arthroplasty with a stemmed prosthesis is a recognized treatment for rheumatoid arthritis of the shoulder. The humeral component of the Copeland cementless surface replacement arthroplasty consists of a cup for surface replacement with a short central peg for primary fixation to the bone. We hypothesized that surface replacement may offer some advantages over stemmed prostheses. METHODS: Between 1986 and 1998, seventy-five shoulders underwent surface replacement arthroplasty (thirty-three hemiarthroplasties and forty-two total shoulder arthroplasties) for the treatment of rheumatoid arthritis. The results of these procedures were reviewed after an average duration of follow-up of 6.5 years. Patients were assessed with use of the Constant score, a patient satisfaction score, and radiographs. RESULTS: The average Constant score was 47.9 points (age and sex-adjusted score, 71%) in the hemiarthroplasty group and 53.4 points (age and sex-adjusted score, 76%) in the total shoulder replacement group. The mean range of active flexion improved from 50 degrees in the hemiarthroplasty group and 47 degrees in the total shoulder replacement group to 101 degrees and 104 degrees, respectively. Seventy-two of the seventy-five shoulders were considered by the patients to be much better or better at the time of the review. Of the sixty-eight humeral implants that were evaluated radiographically, fifty-six (82%) showed no lucencies, eleven (16%) showed localized lucencies of <1 mm in width, and one was definitely loose. Of the thirty-nine glenoid implants that were evaluated radiographically, nineteen (49%) showed no lucencies, nineteen showed localized lucencies of <1 mm, and one was definitely loose. No lucencies were observed adjacent to the hydroxyapatite-coated implants. Thirty-nine (57%) of the sixty-eight shoulders showed some degree of superior subluxation. Three patients required a major reoperation: two required a revision because of loosening of both components, and one patient with pain at the site of a hemiarthroplasty had a revision to a total shoulder arthroplasty to provide relief. CONCLUSIONS: The indications for this surface replacement are the same as those for the conventional stemmed prostheses, but the surface replacement has the advantage of bone preservation as well as avoidance of the potential complications associated with a long humeral stem in rheumatoid bone. This procedure is not suitable for severely damaged joints in which the humeral head is insufficient or too soft. LEVEL OF EVIDENCE: Therapeutic study, Level IV (case series [no, or historical, control group]). See Instructions to Authors for a complete description of levels of evidence.
15305245 The use of methotrexate in rheumatoid arthritis. 2004 Aug OBJECTIVE: To address the long-term efficacy and toxicity issues related to methotrexate (MTX) and compare it with other disease-modifying antirheumatic drugs (DMARDs). METHODS: Review of the international literature on the clinical use of MTX in rheumatoid arthritis (RA) disease. RESULTS: MTX has emerged as a relatively safe and effective treatment for RA that compares favorably with other therapies, particularly because of its considerably longer median drug survival. The toxicity profile of MTX is well established and includes serious and sometimes fatal liver disease, pneumonitis, and cytopenias. Hence, regular and careful monitoring of patients taking MTX is essential, particularly when MTX is combined with other DMARDs. Folate supplementation can reduce some of the most common side effects of MTX, but it has not yet been established whether this translates into a reduced risk of serious disease. Another potential approach to reducing the toxicity of MTX is therapeutic drug monitoring and dose individualization. However, correlations between pharmacokinetics and clinical response have been addressed in only a few studies and with conflicting results. CONCLUSIONS: MTX is an effective DMARD with a relatively safe profile compared with other therapies. Folate supplementation can significantly reduce the risk of MTX toxicity. Finally, it is essential that patients be monitored carefully to reduce the potential serious toxicities of MTX.
15081107 Inconsistent susceptibility to autoimmunity in inbred LEW rats is due to genetic crossbree 2004 May We recently identified a single-nucleotide polymorphism in the Ncf1 gene, a component of the NADPH oxidase complex, to be the cause of one of the strongest identified loci for arthritis severity in rats. This polymorphism was found to be naturally occurring in a collection of inbred rat strains as well as in wild rats. Among the inbred strains we found that different LEW substrains (LEW/Ztm and LEW/Mol), originating from different breeders, showed an allelic discrepancy in Ncf1, suggesting an impact on arthritis susceptibility between these substrains. In fact, the LEW/Mol strain was completely resistant to pristane-induced arthritis, in contrast to the LEW/Ztm strain, which was susceptible. Moreover, the LEW/Mol strain had higher production of radical oxygen species in peripheral blood leukocytes, a phenomenon most likely regulated by the polymorphisms in the Ncf1 gene. However, the phenotypic difference between LEW/Mol and LEW/Ztm is most likely a combination of several genes, of which Ncf1 is suggested to be the major regulating gene. This has also been confirmed by previous linkage analyses involving the LEW/Ztm strain which shows that a QTL on chromosome 12, most likely caused by polymorphism of Ncf1, is the major regulatory gene but that other loci are contributing. That more genes are likely to contribute was shown by a complete genome comparison of the LEW/Ztm and the LEW/Mol rat strains that uncovered an introduction of approximately 37% non-LEW genome into the LEW/Mol strain, which probably was caused by past crossbreeding. Therefore, the LEW/Mol should be regarded as a recombinant inbred strain.
12928941 [Interleukin-1 receptor antagonist anakinra (Kineret) for treatment of rheumatic arthritis 2003 Aug New treatment strategies in rheumatoid arthritis are targeted to interfere with critical mediators of inflammation. Proinflammatory cytokines like IL-1 beta and TNFalpha play a crucial role in induction and maintenance of synovitis, pannus formation and bone and cartilage destruction. Within a few years, these morphological changes may lead to joint destruction and consecutively to functional impairment. Since April 2002 a recombinant human interleukin-1 receptor antagonist (Anakinra) is available in Germany for treatment of patients with rheumatoid arthritis. Anakinra (Kineret(R)) is approved for therapy in combination with methotrexate and should be applied according to guidelines established by the German Rheumatology Society for the use of biologicals in treatment of patients with rheumatoid arthritis. The approval of anakinra as a new therapeutic is based on data obtained in large multicenter, placebo-controlled, and randomised trials in comparison to placebo. Treatment of Anakinra as monotherapy or in combination with methotrexate lead to significant improvement of signs and symptoms of disease as measured by the ACR 20 (or more) response and was associated with a slower radiographic progression with regard to joint space narrowing and development of erosions. Anakinra showed a favourable safety profile with injection side reactions as the predominant side effect that occurs in 70% of patients usually after 10-12 days of treatment and that are mostly mild to moderate and self-limiting. Patients with previous pneumonia or other risk factors for pulmonary infections such as chronic obstructive lung disease seem to show a slightly increased risk of developing infectious complications of the bronchopulmonary system while being on anakinra and should be monitored appropriately. Combining IL-1ra treatment with the use of anti-TNF agents showed an increased risk of infectious complications in clinical studies and is not recommended at present. Studies are currently assessing the use of anakinra for treatment of other rheumatic diseases like psoriatic arthritis, juvenile arthritis or spondylarthropathy.
15045816 [Active arthritis due to cryoglobulinemia based on HCV infection in a patient with RA impr 2004 Feb A 49-year-old Japanese woman was diagnosed with rheumatoid arthritis (RA) based on ACR criteria in May 1999. She developed liver injury after initiation of disease-modifying antirheumatic drugs (DMARDs) and was found to have contracted HCV infection. RA disease activity worsened following restriction of medication due to liver dysfunction. However, 3 mg/day of prednisolone (PSL) resulted in a temporary but marked improvement of RA in December 2001; but arthritis recurred along with Raynaud's phenomenon and palpable purpura. Differential diagnosis between arthritis caused by cryoglobulinemia and exacerbation of RA was important for the selection of appropriate treatment. She manifested non-erosive arthritis on medium and large joints with proteinuria, hematuria and hypocomplementemia. In addition, type III cryoglobulin was detected and chronic active hepatitis was observed on liver biopsy in March 2002. We considered that the main cause for the arthritis was HCV-related mixed cryoglobulinemia. Administration of IFN-alpha resulted in the disappearance of HCV-RNA and cryoglobulin followed by amelioration of arthritis without exacerbation of RA.
14978664 Predictive factors in early arthritis: long-term follow-up. 2004 Feb BACKGROUND: Because recent-onset inflammatory arthritis exhibits considerable clinical and prognostic variability, it is important to attempt to predict which patients are likely to have a poor prognosis as early as possible. Most prognostic studies have looked at patients who fulfilled proposed criteria for a definite diagnosis of rheumatoid arthritis (RA) or other well-defined conditions; less information exists concerning predictive factors for other types of early arthritis. OBJECTIVES: To examine prognosis in early arthritis, the authors assessed the long-term outcome in a cohort of patients who presented with inflammatory arthritis of short duration. Associations between outcome and patient clinical characteristics were analyzed to determine possible prognostic factors. METHODS: Since 1968, patients were selected to be followed up in 2 early-arthritis clinics if they had evidence of inflammatory joint disease and symptom duration was <1 year. Length of follow-up was variable, but was at least 1 year. At last follow-up, patients were classified as being in remission or as having persistent disease. Factors associated with a poor outcome were identified by using formal statistical methods. RESULTS: A total of 121 patients were included in this analysis. Mean disease duration to the first evaluation was 3 months, and median follow-up was 5 years (range, 1 to 30 months). Twenty-one patients (17%) had transient disease defined as total duration of <6 weeks. Sixty-three patients (52%) were in remission at final follow-up, with unclassified patients doing the best. Patients meeting criteria for RA or spondylarthropathies had more persistent disease. Polyarticular disease predicted more persistent disease (P <.05). In multivariable analyses, patients with initial hand involvement were much less likely to achieve remission of their disease (odds ratio, 0.18; 95% confidence interval, 0.05 to 0.66). Only 4 patients had either class 4 function or joint replacement. CONCLUSIONS: Our findings indicate that prognosis in early inflammatory arthritis is generally good, with more than half of all patients achieving remission in our cohort. Patients with unclassified arthritis fared better than those meeting criteria for RA or spondylarthropathy. Of the many clinical variables examined as possible prognostic factors, hand involvement was the strongest predictor of a poor outcome. RELEVANCE: The long follow-up of these patients with early arthritis provides clues for the clinician to the likely course and shows that many patients will do well.
