16922108 Bifid mandibular condyles: report of four cases. 2006 Jul Anatomic variations in the condylar morphology, like bifid mandibular condyles, are a relatively uncommon anomaly. We report four cases (two in patients and two in archived specimens) of bifid mandibular condyles with emphasis on their aetiopathogenesis and radiographic features. A case of bifid mandibular condyles in a patient with rheumatoid arthritis is reported which, to the best of our knowledge, is the first reported case in the literature. CLINICAL RELEVANCE: Anatomical variations, like bifid mandibular condyles, may mimic a fracture/tumour. Therefore, knowledge and awareness about this entity is important for a general dental practitioner.
16320334 Antiferritin antibodies discovered by phage display expression cloning are associated with 2005 Dec OBJECTIVE: Several autoantibodies have been described in individuals with rheumatoid arthritis (RA), leading to interest in the use of such antibodies as diagnostic or prognostic markers in RA as well as in their relevance to disease pathology. The objective of this study was to use a phage display expression cloning system to identify novel autoantibody targets in RA. METHODS: We used immunoscreening of a phage-displayed complementary DNA (cDNA) library to isolate a cDNA clone encoding the ferritin heavy chain polypeptide. Antiferritin antibody levels in patients with early and established RA, healthy controls, and disease controls were measured by enzyme-linked immunosorbent assay. Antibody-positive and antibody-negative individuals were compared with respect to disease severity as measured by the modified Larsen score, demographic variables, rheumatoid factor status, and carriage of HLA-DRB1 shared epitope alleles. RESULTS: Antiferritin antibodies were present in 60 (16%) of 366 patients with established RA, 23 (19%) of 118 patients with early RA, 2 (2.7%) of 73 healthy blood donors, 2 (2.1%) of 94 individuals with osteoarthritis, and 2 (2.1%) of 97 patients with systemic lupus erythematosus (P < 0.01, RA patients versus healthy and disease controls). Antiferritin antibodies were more common in men than in women (28.4% versus 12.2%; P < 0.001), and antiferritin levels were associated with the severity of joint damage (P = 0.01). CONCLUSION: Antiferritin antibodies are observed in a subset of patients with RA, are present early in the disease course, and are associated with the severity of radiographic damage. Further studies are required to explore their potential as diagnostic and prognostic markers in RA.
16011212 Beyond methotrexate: biologic therapy in rheumatoid arthritis. 2005 May Biologics have revolutionised the treatment of RA due to their efficacy, speed of onset and tolerability. Increasing evidence suggests that early intervention is the key to combating RA. The future challenge is to find the best time to introduce biologics into the treatment paradigm in the hope of inducing disease remission--something unthinkable even a decade ago.
15588972 How to assess early rheumatoid arthritis in daily clinical practice. 2005 Feb Rheumatoid arthritis (RA) is a heterogeneous disorder in terms of both clinical presentation and outcome. Our goals in RA are directed towards suppression of signs and symptoms of synovitis, prevention of structural damage, maintenance of functionability and reduction of mortality. IgM rheumatoid factor and anticitrulline antibodies should be recorded in clinical practice since they are prognostic values of outcome. As control of disease activity is pivotal to preventing or at least retarding long-term damage, it is important to define stringent therapeutic aims as well as to follow-up patients in daily practice. The disease activity score 28 is a valuable instrument for this purpose. The assessment of radiographic damage and disability should be assessed regularly. Since increased cardiovascular mortality has been documented even in early RA, other cardiovascular risk factors should be looked for and eventually treated.
16443552 Reversible Epstein-Barr virus-negative lymphadenopathy and bone marrow involved by Hodgkin 2006 Jan We report a case of spontaneous regression of Epstein-Barr virus (EBV)-negative methotrexate-associated lymphadenopathy occurring with Hodgkin's lymphoma in the bone marrow of a 48-year-old woman with rheumatoid arthritis. Following 10 years of treatment with low-dose methotrexate, the patient developed pancytopenia, hypercalcemia, and elevated levels of liver enzymes over the course of 2 months. A computed tomography scan of the abdomen revealed splenomegaly and enlarged abdominal lymph nodes. A bone marrow biopsy demonstrated cellular marrow with 2 paratrabecular granuloma-like lesions composed of histiocytes, fibroblasts, small lymphocytes, a few plasma cells, and scattered CD30(+)CD15(+) Hodgkin's cells, including a classic Reed-Sternberg cell. The results of EBV studies of the bone marrow were negative. Within a month from withdrawal of methotrexate treatment, the patient's symptoms and the abnormalities in the laboratory results had regressed completely. A positron emission tomography scan failed to detect lymphadenopathy. Twelve months later, the patient remains free of symptoms.
16218464 Idiopathic recurrent acute pericarditis: familial Mediterranean fever mutations and diseas 2005 Idiopathic recurrent acute pericarditis (IRAP) is suspected to be an autoimmune phenomenon. We studied 46 consecutive patients. We looked for: 1) the occurrence of new diagnoses of autoimmune diseases during our follow up; 2) HLA typing; and 3) the presence of the most frequent mutations linked to familial Mediterranean fever (FMF gene or MEFV). HLA typing was done in 21 patients at loci B, DRB1, DQA1 and DQB1. MEFV gene was looked in 23 patients using specific primers. During the follow-up we made a new diagnosis of primary Sjögren's syndrome in four patients (8.7%) and of rheumatoid arthritis in one patient (2.2%). HLA B14, DRB1*01 and DQB1*0202 were significantly more prevalent, but we did not find a typical HLA typing. MEFV gene was searched: exon 10 was checked by sequence and the E148Q mutation by restriction site analysis. No mutations were found. In conclusion, the prevalence of definite immunorheumatological diseases and the absence of the mutations linked to FMF reinforce the notion that idiopathic acute recurrent pericarditis is an autoimmune condition.
16207349 Myocardial dysfunction in rheumatoid arthritis: epidemiology and pathogenesis. 2005 Data from population- and clinic-based epidemiologic studies of rheumatoid arthritis patients suggest that individuals with rheumatoid arthritis are at risk for developing clinically evident congestive heart failure. Many established risk factors for congestive heart failure are over-represented in rheumatoid arthritis and likely account for some of the increased risk observed. In particular, data from animal models of cytokine-induced congestive heart failure have implicated the same inflammatory cytokines produced in abundance by rheumatoid synovium as the driving force behind maladaptive processes in the myocardium leading to congestive heart failure. At present, however, the direct effects of inflammatory cytokines (and rheumatoid arthritis therapies) on the myocardia of rheumatoid arthritis patients are incompletely understood.
17315483 [Genetic epidemiology of rheumatoid arthritis: what to expect from Latin America?]. 2006 Dec Rheumatoid arthritis is a chronic and systemic autoimmune disease characterized by inflammation and destruction of the synovial joints. It affects approximately 0.5% of the Latin-American population and is three times more common in women than in men. Evidence of familial aggregation (lambdas=2-17) was the first indication of a genetic susceptibility to disease. As in other autoimmune diseases, it has a complex genetic basis. Results from whole-genome scans indicate that the HLA region contains a significant and consistent set of linked loci. However, HLA accounts for only one-third of the genetic susceptibility of disease, indicating that non-HLA genes are also involved in the disease susceptibility. In Latin-America, association with HLA-DRB1*0404 and TNF -308A alleles has been uniformly established; however, many other candidate genes remain to be studied. The identification of genetic factors conferring susceptibility to rheumatoid arthritis will contribute to the knowledge of the pathogenic mechanisms, ability to predict its occurrence, the development of diagnostic tools, prognosis, and treatment. The genetic epidemiology of rheumatoid arthritis is herein reviewed; a set of recommendations is provided for the design, analysis and interpretation of genetic association studies in the context of Latin-American populations.
16988840 Analysis of p53 and Bak gene mutations in lymphoproliferative disorders developing in rheu 2007 Feb PURPOSE: Individuals affected by rheumatoid arthritis (RA) occasionally develop lymphoproliferative disorders (RA-LPD). To study the molecular changes underscoring the RA-LPD, mutations of p53 and Bak gene were analyzed in RA-LPD with (MTX-LPD) or without methotrexate treatment for RA (non-MTX-LPD). METHODS: Histology and immunophenotype were immunohistochemically examined in 32 cases of MTX-LPD and 21 of non-MTX-LPD. Polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) followed by direct sequencing was employed to detect the mutations of p53 and Bak gene. RESULTS: Frequency of p53 mutations in non-MTX-LPD (47.6%) was significantly higher than that in MTX-LPD (15.6%) (P < 0.05). Among the cases with non-Hodgkin's lymphoma (NHL), the largest category of RA-LPD, the frequency of p53 mutations in the non-MTX-NHL (47.6%) was significantly higher than that in the MTX-NHL (14.8%) (P < 0.05). Interval between the onset of RA and LPD development was significantly longer in LPD with p53 gene mutations (median 228 months) than that without mutations (133 months). LPD with p53 gene mutations had more advanced diseases and an unfavorable prognosis than those without mutations. CONCLUSIONS: MTX-LPD and non-MTX-LPD show similar findings in clinical characteristics, histology, EBV positive rate, and frequency of Bak gene mutations. Whereas the non-MTX-LPD is distinct from the MTX-LPD in its significantly higher p53 mutation frequency.
16287927 Costs and course of disease and function in early rheumatoid arthritis: a 3-year follow-up 2006 Mar OBJECTIVE: To calculate direct and indirect costs and to study disease activity and functional ability over 3 yr in early rheumatoid arthritis (RA). METHODS: Three hundred and three patients with early (< or = 1 yr) RA were recruited during a period of 27 months (1996-1998). Data were recorded during 3 yr to assess disease activity, functional ability, medication, health-care utilization and days lost from work. RESULTS: Within 3 months, improvements were seen regarding all recorded variables assessing disease activity and functional ability, but 15% had sustained high or moderate disease activity throughout the study period. Indirect costs exceeded direct costs in all 3 yr. The average direct costs were 3704 Euros (3297 US Dollars) in year 1 and 2652 Euros ( 2360 US Dollars ) in year 3. All costs decreased, except those for medication and surgery. Compared with men, women had more ambulatory care visits and used more complementary medicine. The indirect costs were 8871 Euros ( 7895 US Dollars) in year 1 and remained essentially unchanged; this was similar for both sexes. Almost 50% were on sick leave or early retirement at inclusion. Sick leave decreased but was offset by an increase in early retirement. The 14 patients who eventually received TNF inhibitors incurred higher costs even before prescription of anti-TNF therapy. CONCLUSION: Disease activity and functional ability improved within 3 months after diagnosis of early RA. Direct costs decreased, except for medication and surgery. Indirect costs remained unchanged. Fifteen per cent of the patients had high or moderate disease activity in all 3 yr, indicating a need for more aggressive early anti-rheumatic therapy.
15789882 Histological features of rheumatoid arthritis patients having antibodies to enterobacteria 2005 Jan OBJECTIVE: To ascertain whether clinically diagnosed rheumatoid arthritis (RA) patients having antibodies to enterobacterial common antigens (ECA) in synovial fluid (SF) have a histological appearance characteristic of RA synovitis. METHODS: Twenty-five RA patients for which synovial biopsy specimens were preserved, were selected from 58 patients with RA tested for antibodies to ECA in SF The synovial tissue specimens were examined histologically using a semiquantitative scoring system with quantitative counts. The correlation of anti-ECA antibody levels with total scores for synovitis and laboratory markers in three RA patient groups (markedly positive, moderately to slightly positive, and negative according to anti-ECA antibody levels) was analyzed statistically. RESULTS: Histologic examination in the markedly positive RA group (total score for synovitis, range 18-20 points) revealed typical histological features of rheumatoid synovitis. Total scores for synovitis were significantly higher in both the markedly positive and moderately to slightly positive RA groups than in the negative RA group. A comparison of anti-ECA antibody levels with total scores for synovitis revealed a strong and significant correlation. Furthermore, levels of anti-ECA antibodies were also correlated with rheumatoid factor and C-reactive protein. CONCLUSION: Clinically diagnosed RA patients having anti-ECA antibodies in SF showed typical or characteristic histological features of RA synovitis. Our data suggest that a group of RA patients with an entrobacterial etiology exists in larger groups of patients with RA which is thought to be a heterogeneous disease.
16331760 In the era of nephelometry, latex agglutination is still good enough to detect rheumatoid 2005 Dec OBJECTIVE: To compare quantitative nephelometry to the traditional semiquantitative latex agglutination (LAT) test for rheumatoid factor (RF). METHODS: We evaluated 564 patients with rheumatoid arthritis (RA) and 155 controls using both techniques. The cutoff value of 40 IU/ml was established for a positive RF result. RESULTS: Sensitivity of LAT and nephelometry was 85.5% and 88.3%, respectively. Both techniques had a similar specificity and a positive predictive value exceeding 95%. Agreement (kappa = 0.86) and correlation (0.87) between the 2 methods were significant. CONCLUSION: In routine practice, and particularly in developing countries such as India, LAT can still be the preferred method for RF determination.
17071051 The use of low dose methotrexate in rheumatoid arthritis - are we entering a new era of th 2006 Dec Methotrexate (MTX) is one of the most commonly used medications in the treatment of rheumatoid arthritis (RA). It has proven efficacy as a sole agent as well as in combination with other disease modifying anti-rheumatic agents (DMARDs) including the newer biological agents. MTX is generally well tolerated although there are a number of potentially serious adverse effects. Of these, haematopoietic suppression, hepatotoxicity and pulmonary toxicity are the more severe and patients are therefore required to have appropriate monitoring while they remain on MTX. In the past, attempts at therapeutic drug monitoring using serum MTX concentrations have been unsuccessful. However, MTX is taken into red blood cells (RBC) where up to four glutamates are added to form MTX polyglutamates (MTXPG(n)). More recently it has been suggested that higher RBC MTXPG(3-5) concentrations may be associated with improved disease control. Genetic variations in enzymes involved in the uptake of MTX into cells and its metabolism are also being examined for their ability to predict drug response and potential for adverse events. While it is unlikely that a single genetic variant will predict efficacy or toxicity there is preliminary evidence that a "pharmacogenetic index" that takes into account the effects of multiple genetic variants maybe useful. Although in their infancy at present, both therapeutic drug monitoring using MTXPG concentrations and pharmacogenomics of MTX may prove useful in the future and are worthy of further investigation.
16043165 The phosphatidylcholine/lysophosphatidylcholine ratio in human plasma is an indicator of t 2005 Oct OBJECTIVES: Lipid second messengers, e.g. lysophosphatidylcholines (LPC) are involved in the pathogenesis of inflammatory diseases, for instance, rheumatoid arthritis (RA). Unfortunately, the analysis of LPC in complex mixtures as present in body fluids is still challenging. DESIGN AND METHODS: Matrix-assisted laser desorption and ionization time-of-flight mass spectrometry (MALDI-TOF MS) was applied for phospholipid (PL) analysis of organic extracts of synovial fluids from patients with RA as well as the corresponding plasma. These data were compared with results obtained by high resolution 31P NMR spectroscopy. RESULTS: Synovial fluids may be replaced by plasma since the analysis of both body fluids gives very similar results. Patients undergoing treatment with TNF-alpha inhibitors (ADALIMUMAB (HUMIRA)) were examined in order to investigate whether the clinically-significant attenuation of disease activity is accompanied by changes of the PL composition of plasma. It will be shown that especially the PC/LPC ratios of plasma represent a reliable measure of inflammation and increase upon therapy. CONCLUSIONS: Since plasma samples are readily available, our approach might be useful to draw conclusions before puncture of the affected joints is necessary and the PC/LPC ratio detected in plasma may serve as an indicator of RA in early stages.
16043681 Paradoxical effect of body mass index on survival in rheumatoid arthritis: role of comorbi 2005 Jul 25 BACKGROUND: Despite high cardiovascular mortality in rheumatoid arthritis (RA), few studies of body mass index (BMI) and obesity as risk factors for death in RA have been published. METHODS: We estimated the effect of BMI on survival in a cohort of 779 patients with RA adjusting for comorbidity, RA disease severity, erythrocyte sedimentation rate (ESR), and other potential confounders. RESULTS: The cohort accrued 123 deaths in 3460 person-years (3.6 deaths per 100 person-years; 95% confidence interval [CI], 3.0-4.2). The BMI was inversely associated with mortality. Patients with BMIs of 30 or higher had the lowest mortality, 1.7 deaths per 100 person-years (95% CI, 1.1-2.5). Mortality was higher in each lower BMI category, reaching its highest rate among patients with BMIs lower than 20 with 15.0 deaths per 100 person-years (95% CI, 9.9-23.0). The survival advantage of high BMI was independent of RA onset age, RA duration, sex, ethnic group, socioeconomic status, smoking status, and use of methotrexate but was lost on adjusting for comorbidity and RA severity. We observed an interaction between BMI and ESR, where the BMI protective influence occurred only if the ESR was low. The BMI x ESR interaction was independent of all covariates, including comorbidity and RA severity. CONCLUSIONS: Body mass has a paradoxical effect on mortality in RA. Patients with high BMI have lower mortality than thinner patients. This effect is mediated in part by comorbidity. The effect of body mass on survival seems to be modified by the level of systemic inflammation.
16950363 Therapeutic efficacy and safety of chaperonin 10 in patients with rheumatoid arthritis: a 2006 Sep 2 BACKGROUND: Chaperonin 10 (heat shock protein 10, XToll) has anti-inflammatory properties related to the inhibition of Toll-like receptor signalling pathways. Our aim was to establish whether chaperonin 10 is safe and effective in the treatment of rheumatoid arthritis. METHODS: In this randomised, double-blind, multicentre study, 23 patients with moderate to severe active rheumatoid arthritis receiving disease-modifying antirheumatic drugs were randomly allocated to three treatment groups receiving intravenous chaperonin 10 twice weekly for 12 weeks at doses of 5 mg (n=8), 7.5 mg (8), or 10 mg (7). The primary outcomes were change in disease activity score (DAS28) and improvement of core disease measures (American College of Rheumatology response score) from baseline to week 12. All analyses were done by intention to treat. This study is registered with the Australian Clinical Trials Registry, number ACTRNO12606000041550. FINDINGS: Primary endpoint measures improved from day 14 in all groups and continued to improve to day 84. By end of study, a 20% improvement of core disease measures was seen in six (86%, 95% CI 43-100), a 50% improvement in four (57%, 14-86), and a 70% improvement in two (29%, 0-57) patients given the highest dose of chaperonin 10. Clinical remission (as defined by a DAS28 <2.6) was achieved in three (13%) of 23 patients. Three individuals dropped out during the study: one in the 5 mg group (rheumatoid arthritis not controlled), one in the 7.5 mg group (adverse event), and one in the 10 mg group (lost to follow-up). The most common adverse events were exacerbation of rheumatoid arthritis (both during and after the study) and upper respiratory tract infection. Only one adverse event was judged to be of severe intensity. INTERPRETATION: Chaperonin 10 seems to be well tolerated and efficacious in treatment of the symptoms of rheumatoid arthritis, at least in the short term.
16707531 Asporin repeat polymorphism in rheumatoid arthritis. 2007 Jan BACKGROUND: Asporin belongs to a family of proteins associated with the cartilage matrix. OBJECTIVE: To investigate the role of the functional polymorphism consisting of an aspartic acid (D) repeat polymorphism located in the ASPN gene in the susceptibility to and clinical outcome of rheumatoid arthritis. METHODS: A total of 803 Spanish Caucasian patients with rheumatoid arthritis and 904 controls of the same ethnic origin and matched for age and sex were included in the study. The asporin D repeat polymorphism was genotyped using polymerase chain reaction with a fluorescent primer. RESULTS: No significant differences were detected in the distribution of the 10 alleles found in our population on comparing patients with rheumatoid arthritis with control groups. Nevertheless, individuals bearing D14 produced rheumatoid factor more often than the rest (85.7% v 72.1%, p = 0.006, odds ratio (OR) = 2.35, 95% confidence interval 1.21 to 4.50), and the mean (SD) onset age was higher in the group of individuals bearing D13 (50.09 (13.94)) compared with the rest (47.21 (14.31)), although the difference did not reach significance (p = 0.06). CONCLUSION: The results do not support a major role for asporin D repeat polymorphism in the susceptibility to rheumatoid arthritis. Nevertheless, they support the influence of this gene on the outcome of the disease.
15818655 Gaps in care for rheumatoid arthritis: a population study. 2005 Apr 15 OBJECTIVE: Treatment guidelines for rheumatoid arthritis (RA) now recommend early, aggressive, and persistent use of disease-modifying antirheumatic drugs (DMARDs) to prevent joint damage in all people with active inflammation, and evaluation by a rheumatologist, when possible. This research assesses whether care for RA, at a population level, is consistent with current treatment guidelines. METHODS: Using administrative billing data from the Ministry of Health in 1996-2000, all prevalent RA cases in British Columbia, Canada were identified. Data were obtained on all medications and all provincially-funded health care services. RESULTS: We identified 27,710 RA cases, yielding a prevalence rate of 0.76%, consistent with epidemiologic studies. DMARD use was inappropriately low. Only 43% of the entire RA cohort received a DMARD at least once over 5 years, and 35% over 2 years. When used, DMARDs were started in a timely fashion, but were not used consistently. Care by a rheumatologist increased DMARD use 31-fold. Yet, only 48% and 34% saw a rheumatologist over 5 and 2 years, respectively. DMARD use was significantly more frequent, persistent, and more often used as combination therapy with continuous rheumatologist care. DMARDs were used by 84% and 73%, 40%, and 10% of people followed by rheumatologists continuously and intermittently, internists, and family physicians, respectively (P < 0.001). NSAID use, physiotherapy, and orthopedic surgeries were similar across these 4 care groups. CONCLUSION: RA care in the British Columbia population was not consistent with current treatment guidelines. Efforts to educate family physicians and consumers about the shift in RA treatment paradigms and to improve access to rheumatologists are needed.
15856950 [Early and late responses to oxidative stress in human dermal fibroblasts of healthy donor 2005 Mar A study was made of the effect of the oxidizing agent potassium chromate (K2CrO4, PC) on cultured dermal fibroblasts of a healthy donor and three patients with rheumatoid arthritis (RA). Characteristics of the rRNA gene (RG) complex-RG copy number, active RG (ARG) dosage, and 18S rRNA content--were determined for each cell line. In cells of the healthy donor, oxidative stress caused by low doses of PC (2-4 microM, 1-4 h) induced an early response, including a 50-80% increase in total RNA and rRNA. An appreciable activation of the nucleolus was observed cytochemically, by silver staining and morphometry. The early response grew considerably lower with the increasing passage number and/or PC concentration. Exposure to 6-12 microM PC for 24 h led to a progressive cell death (late response). The existence and intensity of the early response correlated positively with the cell survival during further culturing. Cells of the RA patients displayed almost no early response even at early passages: total RNA did not increase, and rRNA increased by no more than 10%. Cell disruption (apoptosis) during further culturing was more intense than in the line originating from the healthy donor. The apoptosis intensity characterized by the increase in the content of DNA fragments in the culture medium and in the caspase 3 activity, was inversely proportional to the ARG dosage in the genome. The results provide the first quantitative characterization of the early and late responses of cells to PC-induced oxidative stress and suggest a role of the ARG dosage in cell survival in stress.
16670155 Bone oedema predicts erosive progression on wrist MRI in early RA--a 2-yr observational MR 2006 Dec OBJECTIVES: To investigate if disease assessment by contrast-enhanced dynamic and static magnetic resonance imaging (MRI) and quantitative nanocolloid (NC) scintigraphy gives useful additional information in early rheumatoid arthritis (RA). METHODS: Twenty-seven patients with early RA (disease duration < or =12 months) were followed up for 1 yr and 24 of them for 2 yrs with contrast-enhanced MRI and NC scintigraphy of the wrist joint. Synovial inflammation was assessed by measuring time-dependent enhancement rates (E-rate) from dynamic MRI scans and technetium(99m)-labelled nanocolloid ((99m)Tc-NC) uptake from scintigraphy scans. Synovial membrane hypertrophy, bone oedema and erosions were semiquantitatively scored according to the Outcome Measures in Rheumatology Clinical Trials RA-MRI scoring system from static MR images. Response to the treatment was evaluated based on whether or not > or = 50% improvement was achieved in the tender and swollen joint scores and the Health Assessment Questionnaire score, with normal C-reactive protein (CRP) or erythrocyte sedimentation rate (ESR) levels. Progression of the erosion score on wrist MRI was evaluated as the outcome. RESULTS: The baseline MRI bone oedema score (rho= 0.67), MRI synovitis score (rho= 0.57), ESR (rho= 0.56), CRP (rho= 0.48), E-rate (rho= 0.47) and (99m)Tc-NC uptake (rho= 0.45) were related with the change in the MRI erosion score from baseline to 2 yrs (rho= Spearman's correlation). In the multivariate logistic regression model, the bone marrow oedema score was the only baseline variable that predicted erosive progression at 2 yrs' follow-up (OR 4.2, 95% CI 1.3-13.8). The median (interquartile range) change in the erosion score from baseline to 2 yrs was 0 (0, 0) and 4 (2, 5) in the patients with (n= 9) and without (n= 15) a persistent clinical response over the 2 yrs, respectively (P= 0.001). The non-responders who presented with erosive progression from 1 yr to 2 yrs had higher MRI synovitis scores, bone oedema scores, E-rate and (99m)Tc-NC uptake at 1-yr follow-up than the non-responders without progressive bone damage. CONCLUSION: The degree of local synovial inflammation at baseline, evaluated by dynamic and static MRI and quantitative NC scintigraphy, is closely related to the progression of wrist joint erosions during the first 2 yrs of the disease. Furthermore, at follow-up, if no persistent clinical response is achieved, these imaging methods may help to predict future erosiveness and help in clinical therapeutic decision making.
