Abstract
A 70-year-old man presented with symmetrical arthritis and arthralgias, Raynaud's phenomenon, pleurisy, fever, maculopapular erythema, leuko- and thrombocytopenia, anemia, antinuclear antibodies and hypocomplementemia. His bone marrow morphology was normal. During therapy with corticosteroids he developed pulmonary tuberculosis which responded well to tuberculostatic treatment. Approximately one year after onset of his initial symptoms, myeloblasts were seen in the blood and a few weeks later the bone marrow showed a myeloblastic leukemia. The patient did not respond to cytostatic treatment and died six weeks later. Although this patient presented symptoms suggesting the diagnosis of SLE, in retrospect his condition probably represented an unusual type of preleukemic syndrome.

Abstract
The five Scandinavian countries Denmark, Finland, Iceland, Norway, and Sweden have all contributed essential and unique knowledge to the science of rheumatology. The origins have varied between the countries. Bridges from basic science and international contacts have been essential for the quality and vitality of a small specialty in small countries. Inter-Scandinavian links as manifested in congresses and in the Journal are the visible superstructure of a far deeper and fertile common culture.

Abstract
Systemic sclerosis, scleroderma (SSc) is a disabling condition that shortens life expectancy. Disease heterogeneity and difficulties separating SSc from SSc-like conditions make classification an important issue. Limited cutaneous and diffuse cutaneous SSc, with different severity and survival, have been recognized for several years as distinct subsets. Some authors have suggested an intermediate cutaneous form with intermediate survival. This issue remains unsettled, however. The technique of capillaroscopy is helpful as an adjunct diagnostic tool to separate idiopathic Raynaud's phenomenon from SSc. Digitized video-capillaroscopy is developing as a powerful new method to assess individual capillaries over time. Using the simpler techniques of video-capillaroscopy, different patterns have been described and named 'early', 'active', 'late' and 'slow'. The value of nailfold video-capillaroscopy to distinguish different subsets or provide prognostic information for use in daily practice remains to be assessed. The features of CREST (calcinosis, Raynaud's, oesophagus dysmotility, sclerodactyly, telangiectasias) are not confined to single subsets of SSc. There is no convincing evidence of any advantage for distinguishing the limited, intermediate and diffuse forms of SSc rather than only the limited and diffuse forms.

Abstract
OBJECTIVE To compare the three year safety and efficacy of cyclosporin and parenteral gold in the treatment of early, active, severe rheumatoid arthritis (RA), and to study the reversibility of cyclosporin associated renal dysfunction in patients who discontinued cyclosporin treatment. METHODS The patients continued to receive cyclosporin or parenteral gold in an 18 month open extension to an 18 month randomised, parallel group study. The main efficacy variable was blinded evaluation of radiographic progression of joint damage. Safety variables included serum creatinine, calculated creatinine clearance, and blood pressure. RESULTS Radiographic progression during follow up was similar in both groups. About 60% of the patients in the intention to treat groups (n=272) and about half of the patients in the completer groups (n=114) had definite radiographic progression in joint damage (increases >6 in the Larsen-Dale score), and about one in three also had substantial progression (>18 increase in Larsen-Dale score). Both systolic and diastolic blood pressure were significantly increased in the cyclosporin group compared with the gold group, and 12/139 (9%) versus 3/139 (2%) (p=0.03) had notably raised blood pressure. The mean serum creatinine increased by 28% at the treatment end point in the cyclosporin group as compared with 7% in the gold group. The mean calculated creatinine clearance was reduced by 16% and increased by 1% in the cyclosporin and gold groups, respectively, at the end of the study. At the final follow up visit after discontinuation of cyclosporin (at least three months after treatment was stopped) the mean serum creatinine was increased by 15% and creatinine clearance reduced by 16%. Sustained increases in serum creatinine at this post-treatment end point were mostly seen in patients with a raised serum creatinine during treatment of at least 50%. CONCLUSION Three year changes in radiographic damage during cyclosporin and parenteral gold were similar in patients with early, active RA. Abnormal renal function and raised blood pressure were often seen in the cyclosporin treated patients.

Abstract
OBJECTIVE To assess organ involvement according to a modified Medsger severity scale and its relation to outcome and prognosis in patients with systemic sclerosis. METHODS One hundred consecutive patients observed in Lund with systemic sclerosis were followed up for a period of 14 years. The mean follow up time was 7.7 years. Initial assessment and an annual evaluation was performed for each patient, with a mean visit frequency of 5.6 per patient. RESULTS Age at referral, high total skin score, truncal skin involvement, low vital capacity, low static lung compliance, low Cr-EDTA clearance, and ECG abnormalities at the initial assessment predict poor outcome. A severity scoring system for five organ systems indicates a slow progression of organ dysfunction after recruitment into the study. The female: male ratio was 2:1, the mean age at onset of symptoms was 42.3 (range 3-82), and the mean age at recruitment was 47.2 years (range 17-82). Thirty patients died during the follow up period at the mean age of 61.3 years (range 33-85). The causes of death were directly related to systemic sclerosis in at least 10 patients, infections in six, cancers in nine, and other causes in four patients. The standardised mortality ratio was 3.5 and 3.7 for men and women, respectively. CONCLUSION A high severity score for function of vital organs was shown to predict shortened survival. In this study a severity score based on simple clinical assessment variables was able to predict poor outcome from extensive skin changes, ECG changes, and compromised lung and renal function. Organ dysfunction mainly became manifest during the first five years of the disease, whereafter organ function remained largely stable.

Abstract
The Cochrane collaboration has recently published a systematic review of placebo controlled randomized trials of herbal therapies for rheumatoid arthritis. An extensive search including all languages screened 2500 hits, identified 47 trials and accepted 11 as meeting set quality criteria. Modest efficacy of gamma linolenic acid containing products was supported by 7 trials, 4 trials dealt with 4 different products, and no conclusions could be derived from these. Although it was stated in the review that safety was probably good, this is not apparent from the presented material.

Abstract
OBJECTIVE To study the association between rheumatoid arthritis (RA) and HLA and tumour necrosis factor (TNF) polymorphism in Peruvian mestizo patients in comparison with ethnically similar controls. METHODS Seventy nine patients with RA and 65 ethnically matched healthy controls were genotyped for HLA-DRB1, HLA-DQA1, HLA-DQB1, and TNFalpha and TNFbeta alleles using PCR amplification. Clinical severity was assessed as mild, moderate, or severe in 35 of the patients. RESULTS TNFalpha6 showed the strongest association with disease susceptibility. The TNFalpha6 allele was more common in patients than in controls (p<0.0076) and the proportion of patients with at least one copy of this allele was greater (p<0.015, relative risk 2.35). Among the HLA-DRB1* alleles with the shared epitope sequence, only the DRB1*1402 allele was significantly increased in patients compared with controls (p<0.0311), as was the proportion of patients with at least one copy of this allele (p<0.0232, relative risk 2.74). In contrast, the overall frequency of alleles with the shared epitope was not different in patients and controls. The haplotype HLA-DRB1*1402-DQB1*0301-DQA1*0401 was significantly more common in patients. TNFalpha6 was more common in patients whether or not they had this haplotype. None of the 11 patients lacking the TNFalpha6 allele had severe disease. CONCLUSIONS This study shows for the first time that TNF gene polymorphism is associated with susceptibility to RA in a non-white population. TNFalpha6 and HLA-DRB1*1402 independently conferred significantly increased risk in Peruvian mestizo patients.

Abstract
Enteropathic arthritis is a label for conditions in which gut pathology is believed to be of pathogenic importance for the developing joint disease. Impaired barrier function, as well as immunogenetic mechanism, are implicated. Recent publications have highlighted strong new support for the homing of lymphocytes from the gut mucosa to joint tissue, persistence of antigen- and cytokine-based immune deficiency. A convincing argument was made for the interesting observation that two distinct types of joint involvement with different class II HLA backgrounds occur in patients with inflammatory bowel disease. A new mechanism implicating dimeric HLA-B27 heavy chains in the pathogenesis of enteropathic arthritis is also presented. Despite evidence for persisting antigen presence, antimicrobial therapy seems ineffective in reactive arthritis.

Abstract
OBJECTIVE To assess how serum concentrations of some cytokines, proteases and their inhibitors and cartilage oligomeric matrix protein (COMP) relate to the evolution of clinical disease and joint damage in early rheumatoid arthritis (RA). METHODS Annual assessment was performed in 24 RA patients subdivided into three groups according to disease severity as determined by the radiological progression rate. All patients were followed for 5 yr after inclusion. Functional status, Larsen's radiographic index in hands and feet (joint damage score, JDS) and C-reactive protein (CRP) were assessed annually and compared with interleukin (IL)-6, IL-10, the IL-1 receptor antagonist (IL-1Ra), promatrix metalloproteinase 3 (proMMP-3), tissue inhibitor of metalloproteinases 1 (TIMP-1) and COMP, which were determined by specific immunological tests. RESULTS The median JDS was initially between 4.5 and 7. During the study time the progression of JDS was 1 (median) for patients with slow progression, 33 for patients with intermediate progression and 62 for patients with rapid progression. Changes in CRP and proMMP-3 concentrations over time differed significantly between the groups, but no significant difference was observed for IL-1Ra, TIMP-1 or COMP. ProMMP-3 was closely related to CRP at each time point. IL-6 correlated significantly with CRP at the last four annual follow-up examinations. CRP and proMMP-3 correlated with JDS at the last two or three examinations and the combined levels of these markers over 5 yr correlated significantly with joint damage progression (Spearman rank correlation 0.73 and 0.74 respectively). IL-1Ra showed a weak negative correlation with JDS, and COMP tended to correlate with JDS only at the start. The initial proMMP-3 concentration was the only significant variable predicting rapidly developing joint damage, but the predictive value was low. CONCLUSIONS ProMMP-3 correlated closely at all time points with CRP, but gave little or no additional clinical information regarding inflammation or radiographic progression. IL-1Ra and TIMP-1 showed weaker, acute-phase-like variation, which may reflect pathogenic agonist/inhibitor imbalance in the evolution of RA. COMP, in contrast, did not reflect the inflammatory CRP-related component of the disease or the destructive aspect in this study.

Abstract
The year 2000 was characterized by euphoria among clinicians based on the continued and consolidated success of tumor necrosis factor (TNF) inhibition but also by problems caused by the high cost of this therapy. Looking at the risks and adverse effects has only begun, and there is so far a remarkable lack of publications dealing with this topic. Leflunomide also emerges as an established disease-modifying antirheumatic drug (DMARD). Other therapies include the cyclooxygenase-2 (Cox-2) inhibitors, which are tolerated better by the gastrointestinal system but raise concerns regarding thromboembolism in patients at risk. The enthusiasm regarding Cox-2 inhibitors is somewhat tempered by recent reports of thromboembolic complications, although those have been rare. The advances in research regarding mechanisms of inflammation and pathogenesis continue to generate new therapeutic approaches, which, however, remain mostly experimental. The complexity of genetics has been emphasized by reports on susceptibility and severity relation to TNF, mannose-binding lectin, and gamma-interferon polymorphism. Epidemiologic studies focusing on prevalence, incidence and outcome continue to deliver conflicting messages. One major worry relates to chronic inflammation in RA and other rheumatic diseases as putative cause of accelerated atherosclerosis.

Abstract
In 44 consecutive patients with systemic sclerosis (SSc), plasma concentrations of von Willebrand factor (vWf) were higher than those of the vWf propeptide, but the propeptide showed less variability within patient subgroups. Higher values of the propeptide were observed in patients with early pulmonary involvement. A closer correlation of the propeptide than of vWf to biochemical markers of activity was also evident. Our results suggest that the propeptide, despite a shorter circulating half-time and lower plasma concentrations than vWf, is more useful in the assessment of disease activity in SSc.

Abstract
IL-18, originally identified as interferon-gamma inducing factor (IGIF), is related to the IL-1 family in terms of its structure as well as its processing, receptor, signal transduction pathway and pro-inflammatory properties. IL-18 is also functionally related to IL-12, as it induces the production of Th1 cytokines and participates in cell-mediated immune cytotoxicity. A summary is made of recent advances in the understanding of IL-18 structure, processing, receptor expression and immunoregulatory functions. It focuses on the role of IL-18 modulation in tumours, infections and autoimmune and inflammatory diseases.

METHODS Forty-eight SSc patients, 13 with a diffuse form (dcSSc), 23 with a limited form (lcSSc) and 12 with suspected SSc not fulfilling the ACR criteria, and 31 healthy controls were examined. Serum concentrations of aminoterminal type III procollagen peptide (PIIINP), aminoterminal and carboxyterminal type I procollagen peptides (PINP and PICP) and cross-linked carboxyterminal telopeptide of collagen I (ICTP) were determined by radioimmunoassay. RESULTS Increased serum concentrations of ICTP were found in SSc patients compared with controls. Distinctly higher levels of ICTP were observed in dcSSc than in lcSSc. High serum ICTP was correlated with skin score and acute phase reactants, and with reduced pulmonary function. Serum PIIINP concentration was elevated in both lcSSc and dcSSc. CONCLUSION Augmented collagen catabolism accompanies the increased collagen synthesis in SSc. Serum ICTP concentration is a marker of this feature and also reflects clinical severity.

Abstract
Substantial progress can be noted in the efforts to demonstrate the usefulness of tissue-related markers of disease in rheumatoid arthritis and other joint diseases. The most informative studies use longitudinal analyses of well-characterized patient groups. Emphasis should be on searching for markers which can be of prognostic significance. New markers need to be assessed in relation to existing ones, such as C-polysaccharide reacting protein and erythrocyte sedimentation rate, which, although not specific, are hard to beat as measures of inflammation. A newly identified matrix component, cartilage intermediate layer protein, has features which make it attractive as a potential cartilage specific marker. Many markers may not in the end prove clinically useful. They will, however, give important insight into pathogenic processes, and may help in evaluating new therapy. Finally, markers originally identified in humans have now proven their value in experimental arthritis.

Abstract
Diseases and injuries affecting the locomotor system take a large toll among old and young, and due to changing life style and demographics, the impact will increase in years to come. The Decade of bone and joint 2000-2010 is an umbrella initiative to professionals from different specialities, patient organisations, health industry and not least, governments, to mobilise an offensive against the problems. We need to increase awareness among the public, assess the magnitude of problems, identify effective preventive measures and stimulate research. The decade will be launched in the spring of 2000. We should all help to fill it with meaningful activities.

Abstract
OBJECTIVE To develop and test a severity scale for individual organ involvements in systemic sclerosis (SSc, scleroderma). METHODS An international study group completed the following tasks: (1) developed a glossary of terms including all pertinent variables for 9 potentially affected organ systems; (2) collected prospective data to determine the feasibility and practicality of each proposed variable; (3) revised the initial list of variables; (4) determined the association of each variable with mortality (a proxy for morbidity) using 579 patients in an existing comprehensive longitudinal scleroderma databank; (5) developed a severity grading scale for each organ system by discussion and consensus; and (6) externally validated the scale using an independent group of 680 patients from the same databank. RESULTS Nine organ-specific severity scales were developed from 0 (no documented involvement) to 4 (endstage disease). The data required for scale completion are relatively easy and practical for all physicians to obtain. CONCLUSION This preliminary severity scale will be useful for assessing disease severity status in individual patients both at one point in time and longitudinally. The severity scale will assist in the design and conduct of clinical trials and the comparison of study populations with one another. The scale will serve as a framework for developing a scleroderma disease activity index.

Abstract
Joint cartilage is a dynamic tissue that reacts to trauma, inflammation, and other insults by attempting to repair its matrix. This reaction results in the release of cartilage macromolecules into the body fluids. Analysis of these fluids has identified a limited number of at least somewhat tissue-specific markers of altered cartilage metabolism. Analyses of serum are less specific and less sensitive than analyses of synovial fluid, but their use as research tools in clinical studies, drug development, and experimental work in animal models is increasing.

Abstract
OBJECTIVE To assess the role of T lymphocyte-fibroblast contact in type I collagen production by cultured dermal fibroblasts from normal individuals and from patients with diffuse systemic sclerosis (SSc). METHODS Cell membranes were prepared from activated CD4+ and CD8+ T cells, or type 1 T helper (Th1) clones, and added to confluent fibroblast monolayers. Type I collagen production was measured in culture supernatants, and messenger RNA (mRNA) levels of type I procollagen alpha1 (pro alpha1[I]) and matrix metalloproteinase 1 (MMP-1) were evaluated by Northern hybridization analysis. RESULTS Dose-dependent inhibition of type I collagen production was observed with CD4+ and CD8+ T cells from both SSc patients and controls. Inhibition of type I collagen was significantly less pronounced in fibroblasts from SSc patients than in fibroblasts from controls (P < 0.02). Inhibition was not reversed by the addition of exogenous transforming growth factor beta, interleukin-4, interleukin-1 receptor antagonist, anti-tumor necrosis factor, anti-CD40, or indomethacin, whereas anti-interferon-gamma (IFNgamma) reversed Th1-mediated inhibition. This inhibitory activity was specific for type I collagen, since mRNA levels of pro alpha1(I) were decreased, whereas mRNA levels of MMP-1 were strongly increased. CONCLUSION The production of type I collagen by skin fibroblasts is specifically down-regulated by membranes from activated T cells. The contact-dependent regulatory activity exerted by T cells on fibroblasts depends, at least in part, on the presence of membrane-associated IFNgamma. However, SSc fibroblasts are more resistant to inhibition than are fibroblasts from normal individuals.

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

Abstract
The objective was to study the relationship between the levels of interleukin-1 receptor antagonist (IL-1Ra) and disease activity and the acute-phase response in SLE patients with and without renal involvement. Twenty SLE patients who had distinct active clinical manifestations (eight glomerulonephritis, four systemic vasculitis without kidney involvement, nine skin rash, 12 arthritis, five serositis, four neuropsychiatric manifestations, three thrombocytopenia, one myositis and one haemolytic anaemia) were studied during a period of 8-12 months. Serum and plasma samples were taken at intervals of 6 weeks-4 months and tested for IL-1Ra, IL-1 beta, IL-6, IgG and anti-dsDNA, Clq, C3, C4 and C-reactive protein (CRP). IL-1Ra serum concentrations were increased in most SLE patients with active disease when compared to normal blood donors. However, at the time of flare, significantly higher levels of IL-1Ra were observed in patients with extra-renal disease as compared to other patients (median [range]: 363 [202-3041] and 4847 [268-27180] pg/ml for patients with and without renal involvement, respectively). This difference was not due to proteinuria. IL-1Ra levels did not correlate with SLEDAI score during flares, but they were elevated during flares in patients with extra-renal manifestations. When disease activity was at its highest, IL-1Ra concentrations correlated with IL-1 beta (r = 0.76; P < 0.001), IL-6 (r = 0.60; P < 0.01) and CRP (r = 0.61; P < 0.01), but not with C1q, C3, C4 and anti-dsDNA levels. The study showed that the pattern of inflammatory cytokines in active SLE varies in a manner that is dependent on which organs are involved. A relative absence of IL-1Ra response appears to be a feature characteristic of kidney involvement. IL-1Ra elevation clearly correlates with flares involving other organs.

Abstract
OBJECTIVE To develop and evaluate the effect of a new arthritis education program based on a previous study. METHODS One hundred individuals with established rheumatoid arthritis randomized to an intervention group or a control group completed self-report questionnaires. RESULTS Three months after the education program the patients in the intervention group had increased their knowledge about their disease. They reported increased practice of exercise and joint protection and reduction of disability and pain. After 12 months, increased knowledge and practice of joint protection was maintained. However, there was no longer any difference between the intervention group and the control group regarding reported pain, disability, and practice of exercise. At both intervals the individuals in the intervention group reported an increased ability to handle their pain and a reduction of problems with their disease. The control group remained stable except for a slight increase in pain. CONCLUSION A structured patient education program had positive impact for 3 months, and some improvements were maintained for 12 months. We suggest that patient education should become an integrated part of the total management of rheumatoid arthritis.

Abstract
The carriage of a characteristic sequence of amino acids at position 67-72 in the third hypervariable region of the HLA DRB1 chain has been linked to susceptibility to rheumatoid arthritis (RA). Whether this epitope is also a predictor of more severe disease remains controversial. Cartilage oligomeric matrix protein (COMP) is a protein, the serum levels of which have been found to correlate with large joint destructive disease in previous work. In this paper, we compare DRB1* typing and serum COMP levels in a prospectively observed group of RA patients with or without early hip joint destruction. The COMP levels at study inclusion, median 11 months from onset of symptoms, were significantly higher in the patients with early hip joint destruction compared to the patients in the more benign group. There was no difference in the number of disease susceptibility-related epitopes between the groups. DRB1*04, in contrast, was found among 8/8 patients with hip destruction, but also in 5/8 more benign cases. We conclude that in this type of RA patient, COMP serum levels are more informative predictors of aggressive disease than HLA DRB1* typing.

Abstract
OBJECTIVE To evaluate the usefulness of early treatment with D-Penicillamine (DPA) in rheumatoid arthritis. METHODS The patients were recruited from a Swedish early RA cohort comprising 180 patients. All patients experiencing active and/or erosive disease 2 years from onset were asked to participate in a 2-year placebo-controlled DPA trial. Previous treatment with slow-acting anti-rheumatic drugs (SAARDs) or oral corticosteroids was not allowed. The main outcome variable was radiographic progression in the hands and feet evaluated according to Larsen. Clinical assessment including the Ritchie index, active joint count, and the HAQ-disability index was performed every 6th month. Patients were included in the analyses of efficacy until the endpoint of therapy. RESULTS 111/180 patients were eligible for treatment, and 74 agreed to participate in the trial. 21/33 patients on DPA and 22/41 on placebo completed the study. More patients taking placebo stopped due to lack of response (p < 0.01). 27% of the patients on DPA were withdrawn due to side effects. Radiographic deterioration increased but most clinical variables improved in both trial arms. A large inter-individual variation was observed. The only significant difference in trend over 2 years between DPA and placebo was found for joint tenderness. However, the median trends for most clinical variables showed a more positive effect for DPA. The 37 patients who refused to participate in the trial in general fared somewhat worse than patients taking DPA and somewhat better than patients taking placebo. The remission rate was about the same in all 3 groups (12-13.5%). CONCLUSIONS About two-thirds of all early definite RA patients were eligible for treatment using current criteria. Psychological readiness for early therapy was fairly modest with a high refusal rate. The difference in efficacy between DPA and placebo was small, but was in favour of DPA for most clinical variables. However, only joint tenderness showed a significantly better trend. No significant slowing of radiographic progression by DPA was found.

Abstract
OBJECTIVE To study whether changes in the properties of skin from patients with systemic sclerosis (SSc) are the result of altered metabolism of dermatan sulfate proteoglycans. METHODS Fibroblast cultures were established from skin of healthy controls, and from affected and unaffected skin of patients with SSc. Synthesized proteoglycans were labeled with 3H glucosamine and 35S sulfate. The amount of mRNA of the different dermatan sulfate proteoglycans was determined by hybridization with the corresponding cDNA probes. RESULTS A 2-fold increase in secretion of total proteoglycans was found in cell cultures from affected and normal appearing skin from patients with SSc. The production of 2 different dermatan sulfate proteoglycans was increased. Aggrecan/versican increased 4-fold and decorin 2-fold in cultures of affected skin from patients with SSc. The mRNA for decorin increased 3-fold, while the mRNA level for versican increased only slightly. Similar but less marked changes were noted in cultures from normal appearing skin. In contrast, the biglycan mRNA level decreased and the product could only be found in very small amounts in SSc cultures. CONCLUSION This marked alteration of dermatan sulfate proteoglycan metabolism distinguishes not only affected skin but also normal appearing SSc skin from that of controls. The altered proteoglycan production may affect organization of matrix fibers and thereby the fibrotic process observed in patients with SSc.

Abstract
Rheumatoid arthritis is clinically heterogeneous, and early aggressive therapy is probably not always warranted. A large number of biochemical and biologic markers are under investigation for possible usefulness in diagnostic and prognostic work. These markers can be divided into three main categories: disease specific, inflammatory, and tissue specific. Markers may be useful in the study of prognosis and response to therapy, whereas the diagnostic information they provide is limited. Marker metabolism is largely unexplored, and validation of most marker analyses is lacking. However, they are interesting research tools and may in the end not only teach lessons on the pathogenesis of the disease but also help in selecting patients early for aggressive disease or detecting response or lack of response to therapy.

Abstract
Rheumatoid arthritis (RA) is the dominant form of destructive chronic arthritis with the potential to cause substantial disability and permanent functional impairment. The final extent and progression rate with time, however, varies markedly. In order to study effects of intervention and to support early aggressive and atoxic therapy in selected cases, predictive disease markers are needed. Recent advances regarding joint tissue composition and pathophysiology have defined a number of biological marker candidates which need to be explored for possible prognostic information. Some markers are characteristic for RA, such as rheumatoid factors and certain autoantibodies, which although they are more prevalent among patients with aggressive disease are not sensitive as predictors in early disease. Genetic susceptibility markers have been claimed to be good predictors of persisting arthritis in early synovitis clinics, but their role as severity markers in established disease is limited. Unspecific markers of inflammation, notably ESR or CRP when persistently elevated, are useful to monitor disease course and newer markers need to document their superiority over these. Another group of markers are attractive because of enriched or exclusive occurrence in joint tissue, and altered metabolism in joint disease. Thus, collagen type III propeptides, hyaluronates, and neopterin originating in the synovium could be useful, and, in particular, hyaluronate levels indeed do provide some predictive information. Highly tissue-specific cartilage metabolites include aggrecan fragments, collagen II fragments, cartilage oligomeric matrix protein (COMP) and the extraarticular cartilage matrix protein (CMP). When used alone or in combination in early disease some information can be obtained which may in the future facilitate prognostication. Bone metabolism can be monitored and there are different markers for synthesis and resorption. Meanwhile, whilst the new markers are essential research tools, their routine clinical usefulness remains to be proven.
