Abstract
OBJECTIVE Rheumatoid arthritis (RA) is characterized by erosive joint damage, deterioration of bone mass, and biomechanics. Preclinical evidence suggests a beneficial effect of Janus kinase inhibition (JAKi) on bone properties, but clinical data are scarce to date. In this study, we evaluated the effect of JAKi through baricitinib (BARI) on 1) volumetric bone mineral density (vBMD), bone microstructure, biomechanics, and erosion repair and 2) synovial inflammation in RA patients. METHODS Prospective, single-arm, interventional, open-label, single-center phase 4 study in RA patients with pathological bone status and clinical indication of JAKi (BARE BONE trial). Participants received BARI (4 mg/day) over 52 weeks. To assess bone properties and synovial inflammation, high-resolution computed tomography scans and magnetic resonance imaging were performed at baseline (BL), week 24, and week 52. Clinical response and safety were monitored. RESULTS Thirty RA patients were included. BARI significantly improved disease activity (Disease Activity Score in 28 joints using the erythrocyte sedimentation rate: 4.82 ± 0.90 to 2.71 ± 0.83) and synovial inflammation (RAMRIS synovitis score: 5.3 [4.2] to 2.7 [3.5]). We observed a significant improvement in trabecular vBMD with a mean change of 6.11 mgHA/mm3 (95% confidence interval [95% CI] 0.01-12.26). Biomechanical properties also improved with mean change from baseline in estimated stiffness of 2.28 kN/mm (95% CI 0.30-4.25) and estimated failure load of 98.8 N (95% CI 15.9-181.7). The number and size of erosions in the metacarpal joints remained stable. No new safety signals with BARI treatment were observed. CONCLUSION Bones of RA patients improve with BARI therapy, as shown by an increase in trabecular bone mass and an improvement of biomechanical properties.

Repair of joint damage in patients with rheumatoid arthritis does not relate to previous suppression of inflammation: a subanalysis after 8 years treat-to-target in the BeSt-trial. RMD Open 2023; 9:rmdopen-2023-002995.

Abstract
OBJECTIVES To investigate whether repair of erosions and joint space narrowing (JSN) in rheumatoid arthritis (RA) occurs and whether clinical variables predict this. METHODS Eight-year follow-up data of the BeSt-study were used. Patients with recent onset RA (1987 criteria) were randomised to four treatment strategies and treated-to-target (Disease Activity Score (DAS)≤2.4). Yearly radiographs of hands and feet were scored in non-chronological order by four independent readers, using the Sharp/van der Heijde score (SHS). Damage repair was defined as a negative ΔSHS in an individual joint, seen by ≥3 out of 4 readers and persisting ≥2 consecutive years. Associations between repair and DAS, prednisone use, infliximab use, anticitrullinated protein antibody, gender, age, body mass index, symptom duration and randomisation arm were investigated with logistic regression analyses, corrected for mean SHS. RESULTS Repair was seen in 17 patients (5.3%); 10 had regression of JSN, 7 of erosions, none had both. There were no significant associations in any of the regression analyses. CONCLUSION After 8 years of treatment to target DAS≤2.4 in 508 patients with recent onset RA, repair of JSN and erosions was seen in 17/320 patients (5.3%). Probably due to the rarity of repair, we found no associations with suppression of disease activity or other predictors and repair.

Abstract
Methotrexate (MTX) administration is the gold standard treatment for rheumatoid arthritis (RA), but its effects are limited to preventing the progression of the disease. Therefore, effective regenerative therapies for damaged tissues are still to be developed. In this regard, MTX complexes of general molecular formula M(MTX)·xH2O, where M = Sr, Zn, or Mg, were synthesized and physicochemically characterized by TGA, XRD, NMR, ATR-FTIR, and EDAX spectroscopies. Characterization results demonstrated the coordination between the different cations and MTX via two monodentate bonds with the carboxylate groups of MTX. Cation complexation provided MTX with new bioactive properties such as increasing the deposition of glycosaminoglycans (GAGs) and alternative anti-inflammatory capacities, without compromising the immunosuppressant properties of MTX on macrophages. Lastly, these new complexes were loaded into spray-dried chitosan microparticles as a proof of concept that they can be encapsulated and further delivered in situ in RA-affected joints, envisioning them as a suitable alternative to oral MTX therapy.

Abstract
ObjectiveTo compare the effects of interleukin-6 (IL-6) receptor and tumour necrosis factor inhibition on inducing repair of existing bone erosions in patients with very early rheumatoid arthritis (RA).MethodsProspective non-randomised observational study in patients with active erosive RA with inadequate response to methotrexate (MTX) receiving either tocilizumab (TOC) monotherapy or adalimumab (ADA) with MTX for 52 weeks. Erosion volumes were assessed in metacarpal heads (MCH) and the radius by high-resolution peripheral quantitative CT at baseline and after 52 weeks. Clinical response was monitored using Clinical Disease Activity Index, Simple Disease Activity Index and Disease Activity Score 28-erythrocyte sedimentation rate (DAS28-ESR) scores every 12 weeks.ResultsTOC (N=33) and ADA/MTX (N=33) treatment groups were balanced for age, sex, body mass index, comorbidities, disease and activity, functional state, autoantibody status, baseline bone damage and baseline bone biomarkers. Both TOC (DAS28-ESR: baseline: 6.2±0.5; 52 weeks: 2.3±1.0) and ADA/MTX (6.3±0.6; 2.8±1.2) significantly reduced disease activity. Erosion volumes significantly decreased in the MCH and radius of patients with RA treated with TOC (p<0.001) but not in patients treated with ADA/MTX (p=0.77), where they remained stable in size. Mean decrease in erosion volume in TOC-treated patients was −1.0±1.1 mm3 and −3.3±5.9 mm3 in the MCH and radius of TOC-treated patients, respectively, and −0.05±0.9 mm3 and −0.08±4.1 mm3 in patients treated with ADA/MTX.ConclusionsThe REBONE study shows that TOC monotherapy achieves more pronounced repair of existing bone erosions than ADA/MTX. Hence, IL-6 is a central factor for the disturbed bone homeostasis in the joints of patients with RA.

Abstract
Background Rheumatoid arthritis is an autoimmune inflammatory disease, the specific feature of which is progressive joint destruction induced by synovitis. The universal consensus is that alleviation of the synovitis is essential to prevent joint destruction and achieve clinical remission. Main text We have shown that not only achieving but also maintaining remission is crucial to prevent the progression of joint destruction. Although regeneration of the damaged joints is considered very rare, accumulating evidence shows that it actually occurs in routine clinical practice as a result of strong inhibition of synovitis using highly potent medications. Oral and intravenous medications affect the whole body, but to promote joint regeneration in a particular joint, two potent options are intra-articular steroid injection and synovectomy. Conclusion In situations where strong inhibition of synovitis combined with self-regeneration cannot repair severe joint destruction, regenerative medicine may in the future play a crucial role in the regeneration of damaged joints.

Abstract
BACKGROUND While disease-modifying antirheumatic drugs (DMARDs) are a mainstay of therapy for rheumatoid arthritis (RA), some patients with early RA refuse DMARDs. In anthroposophic medicine (AM), a treatment strategy for early RA without DMARDs has been developed. Preliminary data suggest that RA symptoms and inflammatory markers can be reduced under AM, without DMARDs. PATIENTS AND METHODS Two hundred and fifty-one self-selected patients aged 16-70 years, starting treatment for RA of <3 years duration, without prior DMARD therapy, participated in a prospective, non-randomized, comparative Phase IV study. C-patients were treated in clinics offering conventional therapy including DMARDs, while A-patients had chosen treatment in anthroposophic clinics, without DMARDs. Both groups received corticosteroids and nonsteroidal anti-inflammatory drugs (NSAIDs). Primary outcomes were intensity of RA symptoms measured by self-rating on visual analog scales, C-reactive protein, radiological progression, study withdrawals, serious adverse events (SAE), and adverse drug reactions in months 0-48. RESULTS The groups were similar in most baseline characteristics, while A-patients had longer disease duration (mean 15.1 vs 10.8 months, p<0.0001), slightly more bone destruction, and a much higher proportion of women (94.6% vs 69.7%, p<0.0001). In months 0-12, corticosteroids were used by 45.7% and 81.6% (p<0.0001) and NSAIDs by 52.8% and 68.5% (p=0.0191) of A- and C-patients, respectively. During follow-up, both groups not only had marked reduction of RA symptoms and C-reactive protein, but also some radiological disease progression. Also, 6.2% of A-patients needed DMARDs. Apart from adverse drug reactions (50.4% and 69.7% of A- and C-patients, respectively, p=0.0020), none of the primary outcomes showed any significant between-group difference. CONCLUSION Study results suggest that for most patients preferring anthroposophic treatment, satisfactory results can be achieved without use of DMARDs and with less use of corticosteroids and NSAIDs than in conventional care. LIMITATION Because of the non-randomized study design, with A-patients choosing anthroposophic treatment, one cannot infer how this treatment would have worked for C-patients.

Abstract
OBJECTIVE To monitor size and shape changes of bone erosions and changes in BMD in the vicinity of the erosion and in the periarticular trabecular compartment of patients with RA using high-resolution peripheral quantitative CT (HR-pQCT) imaging and to compare an automated three-dimensional (3D) image processing technique with manual measurements of erosion width and depth. METHODS The shape of 40 bone erosions and composition of bone around the erosions were analysed in the MCP joints of 22 RA patients both manually and by semi-automated 3D image processing at two different time points. Periosteal segmentation was performed using volume growing and morphological operations. Image registration was applied for transfer of baseline segmentations to follow-up datasets. RESULTS Eight erosions decreased in size, 6 increased and 28 remained stable. Increasing erosions were more spherical and smaller at baseline compared with decreasing or stable erosions. BMD in the vicinity of shrinking erosions increased, while it decreased next to expanding erosions. There was moderate agreement in the determination of erosion volume between semi-automated and manual measurements, but agreement was poor when assessing changes in volume over time. CONCLUSION Longitudinal changes in erosion size and shape and of BMD in the vicinity of an erosion can be measured. BMD changes are associated with progression and regression of erosions. However, the semi-automated and manual approaches did not classify longitudinal changes of erosion volume in the same way. Further research is necessary to define the nature of these differences.

Abstract
We report an extremely rare case of massive methotrexate-associated lymphoproliferative disorder (MTX-LPD) arising in the retromolar triangle and lung of a patient with rheumatoid arthritis. The patient was a 75-year-old woman who was referred to our department because of severe pain associated with a unilateral ulcer on the left retromolar triangle. The tumor had an extranodal location in the retromolar triangle and in the right lung. A clinicopathologic examination found a lymphocytic infiltrate with increasingly atypical histopathologic features. Atypical large cells were strongly positive in Epstein-Barr virus-encoded small RNA in situ hybridization and in staining with CD20 antibodies. MTX-LPD was diagnosed based on the medical history and histopathologic results. The lesion responded well to withdrawal of MTX followed by R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) chemotherapy. There have been no signs of recurrence for 4 years since withdrawal of MTX.

Abstract
Rheumatoid arthritis (RA) is a systemic inflammatory disease that can lead to local joint deformations (bone erosions and joint space narrowing) and to extra-articular phenomena, including generalized osteoporosis. In addition, in patients with RA, the risk of vertebral and nonvertebral fractures is doubled. High disease activity (inflammation), immobility, and glucocorticoid use are common factors that substantially increase fracture risk in these patients, on top of the background fracture risk based on classical risk factors such as high age, low body mass, and female gender. New insights on the links between the immune system and the bone system, the field of osteoimmunology, have shown that local and generalized bone loss share common pathways. The receptor activator of nuclear factor κB ligand/osteoprotegerin pathway (RANKl/OPG) is one of the most important pathways, as it is (strongly) upregulated by inflammation. In modern treatment of RA with biologics, for example, TNFα-blocking agents and combination therapy of conventional disease-modifying antirheumatic drugs (DMARDs), clinical remission is a realistic treatment goal. As a consequence, in recent studies, it has been documented that both local and generalized bone loss is absent or minimal in those patients who are in clinical remission.

Abstract
OBJECTIVES To monitor repair of bone erosions using magnetic resonance imaging (MRI) in patients with rheumatoid arthritis (RA) during etanercept combination therapy. METHOD The study population comprised 29 RA patients [biologic-naïve, 28-joint Disease Activity Score (DAS28) ≥ 3.2] starting etanercept combination therapy with disease-modifying anti-rheumatic drugs (DMARDs) and completing the 1-year study period with the same treatment. Clinical and laboratory assessments and MRI of the hand were performed at baseline and at 1 year. MRI findings were scored by two readers using the Rheumatoid Arthritis MRI Scoring System (RAMRIS). Both readers were blind to the chronological order of the MRI scans, the identity of the patients, and clinical and other imaging data. Tenosynovitis was also scored. The intra- and inter-reader intraclass correlation coefficients (ICCs) were calculated, along with the sensitivity to change with the smallest detectable difference (SDD). Repair of erosions was defined as a RAMRIS score of at least 1 point lower than baseline. RESULTS The mean RAMRIS score for erosions did not change but all other inflammatory MRI parameters decreased significantly. In 19 patients, the RAMRIS score for erosions remained unchanged after 1 year. In five patients the score decreased after 1 year, although the decrease exceeded the SDD in only one patient (3.4%). CONCLUSIONS Etanercept combined with DMARDs stopped the progression of erosions, as measured by the RAMRIS, in 82.8% of our RA patients and occasional repair of bone erosions occurred after 1 year of treatment.

Abstract
OBJECTIVE To evaluate the usefulness of magnetic resonance imaging (MRI) in predicting destructive rheumatoid arthritis (RA) in the knee joint, and to compare this method with clinical examination and conventional radiography (CR). METHODS Clinical evaluations of the knee joint, followed by MRI and CR examinations were performed in 30 patients with early RA. The MRI examination included evaluation of inflammation using a synovitis score and evaluation of destruction with an erosion score. The first examinations were performed within 14 months from disease onset. Twenty-eight patients were re-examined after 1 year, and 23 patients after 3 years. 'Disease activity score' (DAS), using a 28 joints score (DAS28); health assessment questionnaire (HAQ); rheumatoid factor (RF); and C-reactive protein (CRP) were also analysed. RESULTS At baseline, MRI found synovitis in 29 patients, of whom 18 also had clinical synovitis. At baseline five patients had 17 MRI erosions, whereas on CR two patients had one erosion each. After 1 year 17 of 35 and after 3 years 28 of 55 MRI erosions were detected also on CR. In only one case CR showed an erosion that was not visible on MRI. The MRI synovitis score (reflecting the extent of the synovitis) at baseline correlated significantly with the number of erosions on MRI both at year 1 and 3, and with the number of erosions on CR at 3 years. In logistic multiple regression analyses the MRI-synovitis score proved to be the best independent predictor of erosiveness. CONCLUSION MRI was superior to clinical examination and CR in detecting erosions. MRI synovitis score was the best independent predictor of erosiveness in the knee joint in patients with early RA.

Abstract
Background: Radiographic progression in clinical trials is assessed by interpreting changes in total radiographic joint score, and the reliability of those scores depends on an evaluation of sum scores. It is not known how consistently changes in individual joints are identified by independent readers and in independent readings. Patients and Methods: 7255 single joints from 178 patients who participated in the Trial of Etanercept and Methothrexate with Radiographic Patient Outcomes (TEMPO) trial were evaluated. Every image was independently scored twice according to the Sharp–van der Heijde method by two independent readers, so that four scores per joint were available. Absolute agreement and consistency of negative and positive erosion change scores across readers and readings were compared on a per-joint level, as well as on a per-patient level. Results: The number of joints showing a change for erosion was very low in this trial: 691/7255 analysed joints had at least one non-zero change score out of four readings. Absolute agreement between readings was remarkably poor: only 12 joints showed a consistently positive or negative change in all four readings. Change scores in opposite directions in the same joint across independent readings were rare (25 joints). Frequency of opposite joint scores in the same patient (mixed change patterns) was reader dependent. Conclusion: Substantial intra and interreader disagreement in scoring change in individual joints is common. Opposite joint scores in the same patient, however, are rare and reader dependent. Notwithstanding these subtle inconsistencies on the individual joint level, the total Sharp score is a useful and discriminatory outcome measure.

Abstract
The Z39Ig protein (complement receptor for C3b and iC3b) is expressed on resident tissue macrophages in various tissues. This study was undertaken to examine the distribution of Z39Ig+cells and their phenotypic features in rheumatoid arthritis (RA) synovium, in comparison with those of osteoarthritis (OA) and psoriatic arthritis (PsA) synovium. Monoclonal anti-Z39Ig antibody was produced by immunizing Z39Ig transfected murine pre B cells and used for the identification of Z39Ig+cells. Z39Ig+cells were further stained with antibodies to macrophages, fibroblast-like synoviocytes, complement receptors and dendritic cells by using the double immunostaining method in normal, RA, OA and PsA synovium. RA synovial mononuclear cells were double-stained using anti-Z39Ig and anti-CD11c antibodies and sorted into Z39Ig+CD11c+cells and Z39Ig+CD11c-cells. These cell populations were then analysed by electron microscopy. The expression of the Z39Ig protein was limited to intimal macrophages in normal, RA, OA and PsA synovium. The numbers of Z39Ig+CD11c+cells and the ratios of Z39Ig+CD11c+cells to Z39Ig+cells were increased in the synovial lining layer of RA as compared with those of OA and PsA. The ultrastructural analysis of Z39Ig+CD11c+cells showed the character of macrophages with many secondary lysosomes and swelling of mitochondria. Z39Ig+ cells appeared to be useful for identification of resident tissue macrophages in normal synovium and the corresponding macrophages in the synovial lining layer of inflammatory arthritis. Expansion of Z39Ig+CD11c+cells was characteristic of RA synovial lining layer.

Expert agreement confirms that negative changes in hand and foot radiographs are a surrogate for repair in patients with rheumatoid arthritis. Arthritis Res Ther 2008; 9:R62. [PMID: 17605816 PMCID: PMC2206368 DOI: 10.1186/ar2220] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2006] [Revised: 04/25/2007] [Accepted: 07/02/2007] [Indexed: 11/28/2022] Open
Abstract
The objective of the present study was to test the hypothesis that experts recognize repair of erosions and, if so, to determine which, if any, morphologic features permitted them to recognize the repair. We also tested whether scoring by a standard method detected repair. Seven experienced readers of radiographs in rheumatoid arthritis were presented with 64 sets of single joints-of-interest at two time points, randomized and blinded for the correct sequence. The readers assessed which joint was better, and recorded whether any of six specific features were seen. Two independent readers, experienced in scoring by the van der Heijde-modified Sharp method who were not on the expert panel, then scored the complete films that included the joint-of-interest. The panel agreed very well on which of two joints was better, and, even though they did not know the true sequence, the panel accurately assigned a sequence slightly better than chance alone (58%) but worse than their agreement on which image was 'better or worse' (78%). The readers therefore indirectly assigned repair by choosing the second film as the best. Putative repair features were seen in cases of both repair and progression, and were not discriminatory. Similar results were obtained when the experts were presented with the entire hand or foot containing the joint-of-interest. In the third repair exercise, two independent readers who scored whole hands and feet using a standard method found a mean negative score in 22/60 joints-of-interest. All 22 joints were also scored as repair by the panel. Repair was detected reliably by a majority of the panel on viewing paired images based on a better/worse decision and assigning sequence in a set of images that were blinded for sequence by an independent project manager. In this test set of images, repair was manifested by a reduction in the size of erosion in many cases. Size was one feature that aided the experts to detect repair but cannot be the only one; the experts had to find other features to determine whether a smaller erosion was the first in a sequence of radiographs in a patient with progressive damage or was the second film in a patient exhibiting repair. The change in size of erosion was also picked up by independent readers applying the van der Heijde-modified Sharp scoring method and was reflected in their scores.

Abstract
We conducted the present study to determine whether repair of erosions occurs in patients with rheumatoid arthritis (RA) treated with conventional disease-modifying anti-rheumatic drugs (DMARDs) and to compare clinical characteristics between patients exhibiting and not exhibiting erosion repair. We included in the study a total of 122 RA patients who fulfilled the 1987 American College of Rheumatology criteria for RA; all patients had paired sequential radiographs of both hands and wrists showing erosive changes at baseline. Patients were classified into two groups according to the presence of repair of erosions at follow up, namely the 'repair observed' and 'repair not observed' groups. Clinical characteristics, disease activity, radiographic scores and treatment in the two groups were compared. Forty-four repairs were observed in 13 patients (10.7%). Compared with the repair not observed group, the functional class of the patients in the repair observed group was lower at baseline (P < 0.01) and the mean disease activity was lower at follow up (P < 0.005). The changes in radiographic scores per year (total radiographic score and erosion score) were lower (P < 0.05 and P < 0.01, respectively) in the repair observed group. No difference in treatment was observed. Repair of erosions was detected in 10.7% of RA patients treated with conventional DMARDs. Repairs were associated with low functional class at baseline and low disease activity at follow up. These observations support the importance of reduction in disease activity in RA patients. Because repair of erosions was detected in a substantial number of patients, assessment of erosion repair should be incorporated into the radiographic evaluation and scoring of RA.

Abstract
Conventional radiography is still regarded the gold standard for imaging techniques in rheumatoid arthritis (RA). It is a very important tool for the diagnosis, the differential diagnosis, and the evaluation of the course and prognosis of the disease. Special advantages of conventional radiography are the worldwide availability and experience with the method over decades and the relatively low costs. Moreover, x-rays can be stored and re-evaluated over long periods of time. Joint damage caused by RA can be quantified by means of scoring methods. The amount of destruction correlates well with functional disability over time. The inhibition of damage progression seen on radiographs is the most important characteristic of a DMARD. Typical radiographic changes are part of the ACR classification criteria of RA. Technically, bone structure can be demonstrated with a high local resolution better than with all other imaging techniques, whereas only indirect conclusions can be drawn concerning soft tissue and cartilage lesions. This review includes recommendations given by the "Commission on Imaging Techniques" of the German Society of Rheumatology regarding technical and personal preconditions, costs, indication as well as practical performance of radiography in RA. In addition, radiographic changes that can be expected in RA including destruction and repair are discussed briefly.

Abstract
OBJECTIVE To describe the changes seen in the wrist in rheumatoid arthritis (RA) on magnetic resonance (MR) imaging obtained at 1 year and 6 years. DESIGN A cohort of patients with RA has been studied prospectively from symptom onset. PATIENTS MR scans of the dominant wrist in 31 patients obtained at 1 year and 6 years were compared for bone erosions, marrow signal change (oedema), synovial thickness and tenosynovitis. RESULTS Twenty-two patients had an increase in erosion score in the interval and three patients showed a decrease in erosion score suggesting erosion healing. Fourteen patients had an increase in oedema score in the interval and eight patients had a decrease in oedema score. Synovial thickness increased in 13 patients and decreased in eight. Tenosynovitis increased in 15 patients and decreased in five. Bone erosions developed immediately adjacent to the tenosynovitis in two patients. CONCLUSIONS MR imaging is useful in following the progress of bone erosions, marrow oedema, synovitis and tenosynovitis in RA.

Abstract
OBJECTIVE The purposes of the present study were: 1) to investigate how the long-term course of outcome and inflammatory variables could be described in individual patients and suitably summarized in groups of patients; 2) to investigate the associations between outcome and inflammatory variables on the basis of the defined summary measures; and 3) to investigate new prognostic aspects of RA by means of frozen sera and DNA specimens. PATIENTS AND METHODS During the period 1966-78, 685 Danish Caucasian patients with RA, classified according to the 1958 American Rheumatism Association (ARA) criteria, were admitted to the Department of Rheumatology of Aarhus University Hospital. For scientific purposes all patients went through the same examination programme, including biochemical variables, clinical evaluation of 68 diarthrodial joints, and radiographic evaluation of 46 diarthrodial joints. Since 1987, data from these patients have been organized in a database. The data are arranged according to onset of disease. This thesis is based on about 600,000 data-points from 257 patients. RESULTS The thesis is based on six studies. The first study shows that early symptomatic improvement of RA during gold treatment was stable over several years, but when evaluated radiographically, the condition continued to deteriorate. In the second study, six main types of radiographic progression were identified: (a) a rare type with no radiographic progression at all (<1%); (b) a type with a slow or moderate onset, but an increasing progression rate (exponential growth type) (9%); (c) a linear type (30%); (d) a type with a moderate to fast onset, and a stable progression rate (the square root type) (11%); (e) a type with a fast onset, but a later decreasing progression rate (the first order kinetics type) (30%) and (f) a type characterized by slow onset, then acceleration and later deceleration (the sigmoid type) (20%). The fact that there was a systematic progression was used to define a system of radiographic events, which could be used as outcome measures in prediction models of the long-term course of RA. The third study shows that low serum levels of the complement-activating serum lectin, mannan (mannose) binding protein (lectin) (MBP = MBL), are associated with a higher erythrocyte sedimentation rate (ESR) (p=0.006), joint swelling score (JS score) (p=0.019), limitation of joint motion score (LM score) (p=0.027), and annual increase in radiographic destruction score (R score) (p=0.053). The fourth study demonstrated a highly significant association between summary measures of inflammatory variables and radiographic outcome, as defined in the second study, indicating that the degree of inflammation is important for the development of destructive joint damage in RA. The fifth study showed that MBL-insufficient patients (two defective structural MBL alleles, or one defective allele combined with a low-expression variant of the normal allele) had a relative risk of a severe radiographic event of 3.1 compared with the MBL competent group (p<0.0001). The sixth study showed that the relative risk (RR) of early interleukin (IL)-1alpha auto-antibodies (aAb) positive patients developing serious radiographic joint destruction was significantly lower than for IL-1alpha aAb-negative patients, RR=0.29 (p=0.04). In rheumatoid factor (RF) positive patients RR was only 0.18 (p=0.02). Patients who seroconverted >2 years after the onset of RA showed the most aggressive development of joint erosion, with RR of serious radiographic joint destruction of 2.56 (p=0.048). Other factors investigated in subgroups of the patients were HLA-DR4, chemokine receptor 5 (CCR 5) genotypes. IL-6 aAb, vascular endothelial growth factor (VEGF) aAb, and interferon (IFN)-gamma aAb. About 80% of the patients were HLA-DR4 positive, indicating the importance of HLA-DR4 as a predisposing factor for RA. There was no association between IL-6 aAb and radiographic outcome, or CCR5 genotypes and radiographic outcome. VEGF aAb and IFN-gamma aAb were quantitatively unimportant. CONCLUSION In spite of a general improvement in single measures of inflammatory variables, and a general deterioration in radiographic outcome of RA, there is a highly significant association between summary measures of inflammatory variables and radiographic outcome. The progression of radiographic damage in RA follows mathematical patterns. A new method of evaluating the long-term radiographic outcome by means of Kaplan-Meier plots is demonstrated. It is shown that MBL and IL-1alpha aAb are predictors of the prognosis of RA and may play important roles in the pathogenesis of RA.

Abstract
We analyzed the CT appearances of degenerative change in the atlanto-odontoid joint (AOJ) in patients with rheumatoid arthritis (RA) and evaluated the effect of these changes on atlanto-axial joint (AAJ) rotation by dynamic CT. This revealed that 9 patients (24%) treated with methotrexate had degenerative features in the AOJ. The ratio of AAJ rotation to the total rotation of the cervical spine was significantly higher in normal subjects (54 +/- 3%) than in patients (38 +/- 12%). The degree of AAJ rotation was significantly lower in the patient group with degenerative features in the AOJ (20.9 +/- 8.4 degrees ) than in patients without degenerative features (28.5 +/- 7.4 degrees ). RA patients with a history of longstanding disease and treatment with antirheumatic drugs may develop AO OA. Although secondary OA was described as healing phenomena in the joints of RA patients, it can limit rotation in the AAJ and cause suboccipital neck pain. A regular check-up of the AAJ and AOJ by means of dynamic CT in all RA patients is proposed to avoid possible antirheumatic drug complications.

Abstract
BACKGROUND Etanercept and methotrexate are effective in the treatment of rheumatoid arthritis but no data exist on concurrent initiation or use of the combination compared with either drug alone. We aimed to assess combination treatment with etanercept and methotrexate versus the monotherapies in patients with rheumatoid arthritis. METHODS In a double-blind, randomised, clinical efficacy, safety, and radiographic study, 686 patients with active rheumatoid arthritis were randomly allocated to treatment with etanercept 25 mg (subcutaneously twice a week), oral methotrexate (up to 20 mg every week), or the combination. Clinical response was assessed by criteria of the American College of Rheumatology (ACR). The primary efficacy endpoint was the numeric index of the ACR response (ACR-N) area under the curve (AUC) over the first 24 weeks. The primary radiographic endpoint was change from baseline to week 52 in total joint damage and was assessed with the modified Sharp score. Analysis was by intention to treat. FINDINGS Four patients did not receive any drug; thus 682 were studied. ACR-N AUC at 24 weeks was greater for the combination group compared with etanercept alone and methotrexate alone (18.3%-years [95% CI 17.1-19.6] vs 14.7%-years [13.5-16.0], p<0.0001, and 12.2%-years [11.0-13.4], p<0.0001; respectively). The mean difference in ACR-N AUC between combination and methotrexate alone was 6.1 (95% CI 4.5-7.8, p<0.0001) and between etanercept and methotrexate was 2.5 (0.8-4.2, p=0.0034). The combination was more efficacious than methotrexate or etanercept alone in retardation of joint damage (mean total Sharp score -0.54 [95% CI -1.00 to -0.07] vs 2.80 [1.08 to 4.51], p<0.0001, and 0.52 [-0.10 to 1.15], p=0.0006; respectively). The mean difference in total Sharp score between combination and methotrexate alone was -3.34 (95% CI -4.86 to -1.81, p<0.0001) and between etanercept and methotrexate was -27 (-3.81 to -0.74, p=0.0469). The number of patients reporting infections or adverse events was similar in all groups. INTERPRETATION The combination of etanercept and methotrexate was significantly better in reduction of disease activity, improvement of functional disability, and retardation of radiographic progression compared with methotrexate or etanercept alone. These findings bring us closer to achievement of remission and repair of structural damage in rheumatoid arthritis.

Abstract
This article reviewed the current methods for scoring radiographic abnormalities in RA with emphasis on reliability. There is disagreement on the expected course of RA with usual treatment and there is no clear resolution of this disagreement although several factors that contribute to this disagreement have been identified. Scoring joint damage has been effective in establishing benefit from drug treatment for nine agents, five within the last 3 years. Scoring will continue to be used to examine the benefit of new agents in the immediate years to come. A panel of experienced readers agreed that some repair of erosion damage was seen with available treatment. The extent of damage that is reversible has not been established and the frequency of any degree of repair remains unknown. Several methods of true measurement of erosions and joint space width have been reported. They have not found a place in daily practice or in research studies, probably because experience is too limited to know whether they are more powerful in detecting real progression of disease than scoring methods. Several problems that are related to standardizing methods of measuring joint space width were identified.

Abstract
The long-term natural history of rheumatoid arthritis includes early radiographic damage and progression, severe functional declines, work disability and increased mortality rates. Emerging evidence suggests that this natural history may be favourably affected by disease-modifying anti-rheumatic drugs (DMARDs), which slow the radiographic progression and functional decline. It is necessary to document both the efficacy of these drugs in randomized controlled clinical trials and their long-term effectiveness in clinical observational studies. Although a 20% improvement in inflammatory measures in the American College of Rheumatology Core Data Set (ACR20) distinguishes DMARDs from placebo in clinical trials, it is not clear that a control of inflammation at this level, or even at 50%, is sufficient to prevent long-term damage. There is limited financial support for long-term observational studies, which depend on data from the clinical experience of rheumatologists. Quantitative databases from clinical care, can be developed to document long-term outcomes in patients with early rheumatoid arthritis to include additional physical, radiographic, laboratory and patient questionnaire quantitative data. Patient self-report questionnaires appear to provide the least expensive and most effective measures toward this goal.

Abstract
OBJECTIVE The characteristic joint damage and disability of rheumatoid arthritis (RA) increase slowly over 10-20 yr. Although it is generally believed that persisting inflammatory synovitis causes joint damage and subsequent disability, the strength of their relationship has not been systematically evaluated. This review describes their progression and interrelationship in treated RA. METHODS MEDLINE and Current Contents databases were searched for the combined terms of rheumatoid arthritis AND X-rays, Health Assessment Questionnaire, slow-acting anti-rheumatic drugs and all identifiable synonyms. This search identified 1303 articles and from these we evaluated in detail 23 reports on the progression of joint damage, 12 reports on the progression of disability and 25 reports dealing with their interrelationship. Additional information was obtained from four data sets comprising 725 RA patients studied cross-sectionally and 33-126 cases followed prospectively for 1-5 yr. X-ray damage was primarily assessed by Larsen and Sharp indices, and disability by the Health Assessment Questionnaire (HAQ). RESULTS Joint damage and disability both increase throughout the duration of RA. Although disability (HAQ score) is correlated with disease duration (correlation coefficients between 0.27 and 0.30), the link between X-ray damage and disability is stronger (correlation coefficients between 0.30 and 0.70). In the earliest phases of RA, X-ray damage and HAQ scores are not related. By 5-8 yr, there are significant correlations with correlation coefficients between 0.30 and 0.50. In late RA (>8 yr), most studies show highly significant correlations between 0.30 and 0.70. CONCLUSIONS Joint damage progresses constantly over the first 20 yr of RA. It accounts for approximately 25% of disability in established RA. The link between damage and disability is strongest in late (>8 yr) RA. However, avoiding or reducing joint damage in both early and established/late RA is likely to maintain function.

Abstract
The way in which a host accommodates invasive facultative intracellular bacteria must be the key to the development of reactive arthritis. Investigators have analyzed the bacterial events at several levels: invasion into host cells, intracellular survival, translocation from the sites of infection to the joints, residence in the joints, and evasion of host defense. Because HLA-B27 is present in higher incidence in patients with reactive arthritis and is an essential gene in the related ankylosing spondylitis, the role of HLA-B27 in host defense is also assumed to be important in the development of reactive arthritis. This review summarizes the various studies in this field.

Abstract
Reactive arthritis was originally defined as a sterile joint inflammation after infection elsewhere in the body, but this view has been challenged in the past decade since different antigens and DNA and RNA of various triggering microbes have been shown to exist at the sites of inflammation in the joints. It has been suggested that microbial antigens, or intact pathogens, are important for the pathogenesis of reactive arthritis, at least in the early phase of the disease, but the exact mechanism of how the pathogens contribute to the development of this usually self-limiting polyarthritis has not been discovered. This article reviews the theories on the role of infectious agents as triggers of reactive arthritis.

Abstract
OBJECTIVE To investigate the adhesion and extravasation capacity of peripheral blood mononuclear cells (PBMC) and the transport of bacterial antigens within these cells during Salmonella infection. METHODS Thirteen patients who were part of 2 outbreaks of Salmonella enteritidis infection were included in this study. The capacity of PBMC from these patients to bind to vascular endothelium in inflamed synovium was tested using a Stamper-Woodruff-type frozen-section assay. The same cells were studied for the presence of Salmonella antigens by immunofluorescence staining. The transendothelial migration of mononuclear cells containing Salmonella or its components through unstimulated endothelial cell layer was quantified. RESULTS The capacity of PBMC to adhere to synovial vessels was significantly increased during Salmonella infection (P=0.0003). Monocytes had a transiently high adhesive state between 2 and 5 weeks after the patients had eaten the contaminated food. The cells containing Salmonella antigens were concentrated in the transmigrated population. CONCLUSION During acute Salmonella infection the increased binding of PBMC to vascular endothelium in inflamed synovium and enhanced transmigration of PBMC containing Salmonella may be the key factors leading to transport of bacterial antigens through the endothelial barrier and initiation of arthritis in susceptible individuals.

Abstract
OBJECTIVES This study was undertaken to examine the role of magnetic resonance imaging (MRI) in the management of patients with juvenile rheumatoid arthritis (JRA). METHODS A Medline search was performed to identify all publications pertaining to MRI in JRA. Further searches and identification of articles from bibliographies identified articles pertaining to plain radiograph imaging in JRA and MRI in adult rheumatoid arthritis. RESULTS Studies in both children and adults have shown superiority of MRI to plain radiography in detecting synovial hypertrophy and articular cartilage abnormalities. Several studies in adults have shown a good correlation of MR images with gross anatomic as well as histological findings at arthroscopy. Biochemical changes that occur before structural changes within the joint may even be detectable with magnetic resonance spectroscopy. CONCLUSIONS MRI holds promise for the assessment of disease progression in JRA and may be useful in serial evaluation, as in clinical trials.

Abstract
Human major histocompatibility complex class I allele HLA-B27 is associated with a group of diseases called spondyloarthropathies. In reactive arthritis (ReA), the disease is triggered by certain infections, e.g. gastroenteritis caused by Salmonella. The host/microbe interaction is abnormal in susceptible individuals leading to inefficient elimination of arthritis-triggering bacteria, fragments of them, or both, after the initial infection. Using transfected human monocytic U937 cell lines, we demonstrate that the expression of the HLA-B27 antigen does not influence the uptake of S. enteritidis into U937 cells in vitro. Interestingly, HLA-B27 remarkably impairs the elimination of S. enteritidis within the HLA-B27 transfected U937 cells. The impaired elimination of ReA-triggering microbes by HLA-B27+ monocytes may offer an explanation for the persistence of ReA-triggering microbes in susceptible HLA-B27+ individuals. This modulation of the host/microbe interaction by HLA-B27 may have an important role in the pathogenesis of ReA.
