Abstract
OBJECTIVE Leukocyte Ig-like receptor A3 (LILRA3) is a soluble receptor belongs to the immunoglobulin superfamily. Our previous studies demonstrated that LILRA3 is a common genetic risk for multiple autoimmune diseases, including RA. Functional LILRA3 conferred increased risk of joint destruction in patients with early RA. We undertook this study to further investigate the pathological role of LILRA3 in joint inflammation of RA. METHODS Soluble LILRA3 was measured by ELISA. LILRA3 plasmids were transfected into human fibroblast-like synoviocytes (FLSs) using electroporation. Activation of extracellular signal-regulated kinase (ERK) and c-Jun N-terminal kinase (JNK) was determined by western blots. Cytokine transcripts were quantified by real-time PCR. Migratory and invasive capacities of FLSs were evaluated using transwell migration and Matrigel invasion assays. FLS apoptosis was analysed using flow cytometry. Colocalization of LILRA3, LILRB1 and HLA-G in RA-FLSs was visualized by immunofluorescence staining. RESULTS Soluble LILRA3 was specifically expressed in synovial fluid and serum LILRA3 was significantly increased and positively correlated with disease activity/severity in RA patients. LILRA3 induced an increased expression of IL-6, IL-8 and MMP3 in RA-FLSs. In vitro LILRA3 stimulation or overexpression promoted RA-FLS migration and invasion, and enhanced phosphorylation of ERK/JNK. Inhibition of ERK/JNK resulted in suppression of IL-6/IL-8 expression in LILRA3-stimulated RA-FLSs. LILRA3 was co-localized with its homologue LILRB1 and shared ligand HLA-G in RA-FLSs. CONCLUSION The present study provides the first evidence that soluble LILRA3 is a novel proinflammatory mediator involved in synovial inflammation by promoting RA-FLS activation, migration and invasion, probably through the ERK/JNK signalling pathways.

Abstract
Spondyloarthritis (SpA) constitute a group of chronic inflammatory immune-mediated rheumatic diseases characterized by genetic, clinical, and radiological features. Recent efforts have concentrated on identifying biomarkers linked to axial SpA associated with inflammatory bowel disease (IBD), offering predictive insights into disease onset, activity, and progression. Genetically, the significance of the HLA-B27 antigen is notably diminished in ankylosing spondylitis (AS) associated with IBD, but is heightened in concurrent sacroiliitis. Similarly, certain polymorphisms of endoplasmic reticulum aminopeptidase (ERAP-1) appear to be involved. Carriage of variant NOD2/CARD15 polymorphisms has been demonstrated to correlate with the risk of subclinical intestinal inflammation in AS. Biomarkers indicative of pro-inflammatory activity, including C-reactive protein (CRP) along with erythrocyte sedimentation rate (ESR), are among the consistent predictive biomarkers of disease progression. Nevertheless, these markers are not without limitations and exhibit relatively low sensitivity. Other promising markers encompass IL-6, serum calprotectin (s-CLP), serum amyloid (SAA), as well as biomarkers regulating bone formation such as metalloproteinase-3 (MMP-3) and Dickkopf-related protein 1 (DKK-1). Additional candidate indicators of structural changes in SpA patients include matrix metalloproteinase-3 (MMP-3), vascular endothelial growth factor (VEGF), tenascin C (TNC), and CD74 IgG. Fecal caprotein (f-CLP) levels over long-term follow-up of AS patients have demonstrated predictive value in anticipating the development of IBD. Serologic antibodies characteristic of IBD (ASCA, ANCA) have also been compared; however, results exhibit variability. In this review, we will focus on biomarkers associated with both axial SpA and idiopathic intestinal inflammation, notably enteropathic spondyloarthritis.

Abstract
Rheumatoid arthritis (RA) is an autoimmune disease characterized by systemic inflammation, joint tissue damage, pain, and synovitis. It leads to deformity of joints, disability, and even premature death. Markers of inflammation are highly expressed in synovium fluid and serum of arthritic patients and play an important role in the pathophysiology of RA. These transcription factors promote the fabrication of type I interferons and inflammatory cytokines. In RA, degradation of synovial cartilage and bone results from stimulation of proinflammatory cytokines. Citronellol (Ct), a monoterpene alcohol, is found in citrus fruits and essential oils of many aromatic plants. It possesses numerous pharmacological properties such as antioxidant activity and potential antinociceptive and anti-inflammatory effects. Keeping in view the significant anti-inflammatory role of Ct, a trial of 28 days was conducted. Ct was administered orally at three different doses (25, 50, and 100) mg/kg in Freund's adjuvant-induced arthritic rats, and the results were compared with piroxicam, chosen as the standard drug. The antiarthritic activity of the compound was evaluated through measurements of arthritic scoring and plethysmometry before and after treatment. The blood biochemical and hematological parameters and histopathological analyses were performed. Additionally, qPCR was conducted to analyze the mRNA expression levels of TNF-α, IL-1β, NF-κB, MMP3, IL-6, and IL-4 in the blood. ELISA was performed to evaluate the levels of PGE2. The results demonstrated that Ct showed significant results at all doses, but the highest dose proved to be most significant in terms of decreasing arthritic scoring and paw edema, indicating the antiarthritic potential of Ct. Furthermore, the compound was found to downregulate all the proinflammatory cytokines (TNF-α, IL-1β, NF-κB, MMP3, and IL-6) and upregulate the anti-inflammatory cytokine (IL-4). The levels of PGE2 were also reduced which further supported the antiarthritic effects of Ct and validated it as a potential antiarthritic candidate.

Abstract
Rheumatoid arthritis (RA) is a self-immune inflammatory disease characterized by joint damage. A series of cytokines are involved in the development of RA. Oncostatin M (OSM) is a pleiotropic cytokine that primarily activates the Janus kinase (JAK)/signal transducer and activator of transcription (STAT) signaling pathway, the mitogen-activated protein kinase (MAPK) signaling pathway, and other physiological processes such as cell proliferation, inflammatory response, immune response, and hematopoiesis through its receptor complex. In this review, we first describe the characteristics of OSM and its receptor, and the biological functions of OSM signaling. Subsequently, we discuss the possible roles of OSM in the development of RA from clinical and basic research perspectives. Finally, we summarize the progress of clinical studies targeting OSM for the treatment of RA. This review provides researchers with a systematic understanding of the role of OSM signaling in RA, which can guide the development of drugs targeting OSM for the treatment of RA.

Abstract
BACKGROUND Matrix metalloproteinases, as components of the proteolytic system, are deemed to be implicated in the pathogenesis and progression of several rheumatic diseases. Their role in spondyloarthritis has been investigated by several studies. OBJECTIVE This article aims to review and summarize the current knowledge related to metalloproteinases in patients with spondyloarthritis. METHODS To examine the association between matrix metalloproteinases and spondyloarthritis, we conducted a narrative review using a literature search in SCOPUS for English-language sources. The search included studies published from the database inception to December 2020. RESULTS A total number of 74 articles were included. It was found that levels of matrix metalloproteinases 3 were higher in radiographic axial spondyloarthritis patients and seemed to play a role in the progression of joint damage. The levels of matrix metalloproteinases 1, 2, and 9 were upregulated in psoriatic arthritis patients compared to psoriasis and could identify psoriasis patients who would develop rheumatic manifestations. The levels of matrix metalloproteinases correlated significantly with disease activity in ankylosing spondylitis and decreased upon treatment with Tumor Necrosis Factor inhibitors (TNFi). CONCLUSION Excessive matrix metalloproteinases activity is associated with articular destruction. Their levels can reflect disease activity, structural damage, and response to TNFi in patients with spondyloarthritis. Nevertheless, further studies are needed to confirm these results.

Abstract
Anti-citrullinated protein antibodies (ACPAs) are highly specific for the diagnosis of rheumatoid arthritis (RA). However, about one-third of RA patients are negative for ACPAs, which presents a challenge to the early diagnosis of RA. The purpose of this study was to analyze differences in lymphocyte subsets and CD4+ T cell subsets between ACPA+ and ACPA- RA patients, and to evaluate the value of matrix metalloproteinase-3 (MMP-3) as a diagnostic and monitoring marker in ACA- RA patients. A total of 145 ACPA+ RA patients, 145 ACPA- RA patients, and 38 healthy controls (HCs) were included in this study. Peripheral lymphocyte subsets were detected using flow cytometry, and serum MMP-3 was detected using chemiluminescence. Information about joint symptoms, other organ involvement, and related inflammatory markers was also collected. The results showed that, compared to ACPA- RA patients, ACPA+ cases had greater imbalances between peripheral CD4+ T cell subsets, mainly manifested as an increase in T-helper 1 (Th1) cells (p < 0.001) and decrease in regulatory T (Treg) cells (p = 0.029). This makes these patients more prone to inflammatory reactions and joint erosion. MMP-3 levels in ACPA+ and ACPA- RA patients were significantly higher than in HCs (p < 0.001), and MMP-3 could effectively distinguish between ACPA- RA patients and HCs (area under the curve [AUC] = 0.930, sensitivity 84.14%, specificity 92.11%). MMP-3 was also a serum marker for distinguishing between RA patients with low and high disease activities. Further analysis showed that MMP-3 was positively correlated with the levels of inflammatory markers and disease activity, and negatively correlated with the levels of lymphocyte subsets. In addition, with improvements in the disease, MMP-3 levels decreased, and further increased as the patients started to deteriorate. In summary, our research showed that there was a mild imbalance between peripheral CD4+ T cell subsets in ACPA- RA patients. MMP-3 may be used as a potential marker for early diagnosis of ACPA- RA. MMP-3 was an important index for RA disease evaluation, disease activity stratification, and prognosis.

Abstract
Circadian rhythm is a natural, endogenous process whose physiological functions are controlled by a set of clock genes. Disturbance of the clock genes have detrimental effects on both innate and adaptive immunity, which significantly enhance pro-inflammatory responses and susceptibility to autoimmune diseases via strictly controlling the individual cellular components of the immune system that initiate and perpetuate the inflammation pathways. Autoimmune diseases, especially rheumatoid arthritis (RA), often exhibit substantial circadian oscillations, and circadian rhythm is involved in the onset and progression of autoimmune diseases. Mounting evidence indicate that the synthetic ligands of circadian clock genes have the property of reducing the susceptibility and clinical severity of subjects. This review supplies an overview of the roles of circadian clock genes in the pathology of autoimmune diseases, including BMAL1, CLOCK, PER, CRY, REV-ERBα, and ROR. Furthermore, summarized some circadian clock genes as candidate genes for autoimmune diseases and current advancement on therapy of autoimmune diseases with synthetic ligands of circadian clock genes. The existing body of knowledge demonstrates that circadian clock genes are inextricably linked to autoimmune diseases. Future research should pay attention to improve the quality of life of patients with autoimmune diseases and reduce the effects of drug preparation on the normal circadian rhythms.

Abstract
Traditional biochemical methods for enzyme detection are mainly based on antibody-based immunoassays, which lack the ability to monitor the spatiotemporal distribution and, in particular, the in situ activity of enzymes in live cells and in vivo. In this review, we comprehensively summarize recent progress that has been made in the development of small-molecule as well as material-based fluorogenic probes for sensitive detection of the activities of enzymes that are related to a number of human diseases. The principles utilized to design these probes as well as their applications are reviewed. Specific attention is given to fluorogenic probes that have been developed for analysis of the activities of enzymes including oxidases and reductases, those that act on biomacromolecules including DNAs, proteins/peptides/amino acids, carbohydrates and lipids, and those that are responsible for translational modifications. We envision that this review will serve as an ideal reference for practitioners as well as beginners in relevant research fields.

Matrix metalloproteinase-3 or MMP3 also known as stromelysin-1 is an enzyme that is actively involved in joint destruction in rheumatoid arthritis (RA) patients. Screening the last three decades, it appears that serum levels of MMP3 reflect positively RA disease activity, joint and bone injury, and radiological erosion and predict disease outcome and drug responsiveness as summarized in several publications reporting outcomes on more than 8000 patients with RA. MMP-3 monitoring should be embedded in the routine assessment and accompany therapeutic modalities, in personalized medical RA management.

Abstract
Synovial fibroblasts (SF) contribute to the pathogenesis of osteoarthritis (OA), but the effects of intra-articular cytokines on SF are not completely understood. The aim of this study was to characterize the interplay between tumor necrosis factor (TNF)α and the anti-inflammatory interleukin (IL)-10. Non-immortalized human SF and SF of the human cell line K4IM were stimulated with recombinant TNFα, IL-10, or TNFα + IL-10 (10 ng/ml each) for 24 h or transduced with an adenoviral vector overexpressing human IL-10 (hIL-10) and subsequently treated with 10 ng/ml TNFα for 24 h. Effects on the gene expression and protein synthesis of IL-6, IL-10, matrix metalloproteinases (MMP)-1, -3, type I collagen, β1-integrin, and CD44 were investigated via real-time detection polymerase chain reaction, immunofluorescence labeling, flow cytometry, and Western blotting. IL-10 release by transduced SF was confirmed with enzyme-linked immunosorbent assay. Both cell populations were activated by TNFα and by TNFα + IL-10, increasing their gene expression and protein synthesis of IL-6, IL-10, MMP-1, and MMP-3 and altering the synthesis of type I collagen, β1-integrin, and CD44. hIL-10 overexpression greatly elevated the gene expression and protein synthesis of IL-10. However, transduction did not significantly affect the gene expression of IL-6, MMP-1, and MMP-3 in SF. The increased expression of pro-inflammatory and catabolic mediators in TNFα-activated SF indicates their role in OA pathogenesis, suggesting they are a potential therapeutic target. Although the vigorousness of the responses of non-immortalized SF and K4IM clearly differ, the K4IM cell line seems to be a suitable model for non-immortalized human SF.

Abstract
Osteoarthritis (OA) is the most prevalent disease of articular joints characterized by joint space narrowing on X-ray, joint pain, and a loss of joint function through progressive cartilage degradation and intermittent synovial inflammation. Current in vitro models of OA are often monolayer cultured primary cells exposed to high concentrations of cytokines or chemokines, usually IL-1β or TNF-α. IL-1β could play a role in the early progression or even initiation of OA as evidenced by many of the in vitro studies. However, the inconsistent or outright lack of detectable IL-1β combined with high concentrations of the natural inhibitor IL-1Ra in the OA synovial fluid makes the idea of OA being IL-1β-driven questionable. Further, other stimulants, including IL-6 and matrix fragments, have been shown in vitro to cause many of the effects seen in OA at relevant concentrations found in the OA synovial fluid. More work with these stimulants and IL-1β-independent models needs to be done. Concurrently, research should be conducted with patients with OA as early as possible in the progression of their disease to be able to potentially identify, target, and treat the initiation of the disease.

Abstract
Osteoarthritis (OA) of the knee is often characterized by joint space narrowing on X-ray, knee pain, and a loss of joint function through progressive cartilage degradation and intermittent synovial inflammation. The objective of this work was to develop an in vitro model in a clinically relevant system. Normal human synovial fibroblasts were cultured with U937 cells for 3 days then combined with a chondrogenic stem cell pellet for another 4 days. This culture system mimicked many of the aspects of early stage OA including production of cytokines and degradative enzymes, MMP-1 and MMP-3, resulting in a conditioned medium profile similar to OA synovial fluid. This catabolic environment resulted in the release of glycosaminoglycan (GAG) from the pellet. In a similar manner to early stage OA, the pellet had increased aggrecan and collagen II expression. All of these effects are hallmarks of early stage OA. This relatively simple tissue model containing a 3D cartilage component interacting with synoviocytes and macrophages could be useful to understand early causes and progression of OA. It can be scaled easily thus useful for high throughput screening of disease modifying drugs in a clinically relevant system.

Abstract
The activity of rheumatoid arthritis (RA) correlates with the expression of proteases. Among several proteases, matrix metalloproteinase-3 (MMP-3) is one of the biological markers used to diagnose RA. The active form of MMP-3 is a key enzyme involved in RA-associated destruction of cartilage and bone. Thus, detection of active MMP-3 in serum or in vivo is very important for early diagnosis of RA. In this study, a soluble MMP-3 probe was prepared to monitor RA progression by detecting expression of active MMP-3 in collagen-induced arthritis (CIA) mice in vivo in both serum and fibroblast-like synoviocytes (FLSs). The MMP-3 probe exhibited strong sensitivity to MMP-3 and moderate sensitivity to MMP-7 at nanomolecular concentrations, but was not sensitive to other MMPs such as MMP-2, MMP-9, and MMP-13. In an optical imaging study, the MMP-3 probe produced early and strong NIR fluorescence signals prior to observation of erythema and swelling in CIA mice. The MMP-3 probe was able to rapidly and selectively detect and monitor active MMP-3 in diluted serum from CIA mice. Furthermore, histological data demonstrated that activated FLSs in arthritic knee joints expressed active MMP-3. Together, our results demonstrated that the MMP-3 probe may be useful for detecting active MMP-3 for diagnosis of RA. More importantly, the MMP-3 probe was able to detect active MMP-3 in diluted serum with high sensitivity. Therefore, the MMP-3 probe developed in this study may be a very promising probe, useful as a biomarker for early detection and diagnosis of RA.

Abstract
This report describes 3 year old girl with the unusual presentation of polyarticular juvenile idiopathic arthritis (JIA) with anti-cyclic citrullinated peptide (anti-CCP) antibodies and a positive rheumatoid factor (RF). She was initially treated with a nonsteroidal anti-inflammatory drug (NSAID; ibuprofen) followed by methotrexate (MTX, 10 mg/m2/week) and prednisolone (0.25 mg/kg/day), but these treatments were ineffective. Administration of tocilizumab, a humanized antihuman interleukin-6 receptor monoclonal antibody, promptly improved her clinical manifestations, and she has been in complete remission (DAS28 <2.6) without bone erosion and/or destruction. Positivity for both antibodies (anti-CCP and RF) can forecast the severity of JIA (radiographic bone destruction). In such cases the administration of biologic remissive therapy may be prudent early in the disease course.

Abstract
OBJECTIVES To determine whether aquaporins (AQPs) are expressed in the synovial tissues of patients with OA and RA, and to examine the patterns of expression in patients with and without hydrarthrosis. METHODS AQPs were detected in synovial tissue samples from patients with OA and RA using RT-PCR and immunohistochemistry. Fibroblast-like synoviocytes (FLSs) from patients with OA and RA were cultured and stimulated with TNF-alpha. The expression of AQPs in FLSs was examined using RT-PCR and western blot analyses and the function of aquaglyceroporins was examined by a glycerol uptake assay. RESULTS AQP1, -3 and -9 mRNAs were expressed in synovial tissues from patients with OA and RA. AQP1, -3 and -9 proteins were also detected by immunohistochemistry. AQP9 mRNA was expressed more strongly in the synovial tissues of OA patients with hydrarthrosis than those without. AQP9 mRNA and protein expression were strongly induced with TNF-alpha treatment in FLSs, whereas the expression of AQP1 and -3 mRNAs was not induced with TNF-alpha treatment. AQP9 as an aquaglyceroporin was induced by TNF-alpha. CONCLUSIONS AQP9 mRNA was detected in synovial tissues from OA and RA patients with hydrarthrosis. AQP9 expression was strongly induced in FLSs with TNF-alpha. Although the functions of AQP1, -3 and -9 in synovial tissues remain to be elucidated, it suggested that AQP9 might be related to the pathogenesis of hydrarthrosis and inflammatory synovitis.

Abstract
Tocilizumab, a biological agent developed in Japan, is a human anti-interleukin-6 (anti-IL-6) receptor antibody. Rheumatoid arthritis improves with its use. A remission rate of 59% is attainable, as measured by disease activity score 28 (DAS28) in the SAMURAI study. However, in tocilizumab treatment, C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) levels drop to negative values; therefore we sought to utilize a different index for measuring its efficacy. In order to evaluate the effects of tocilizumab we carried out this study using clinical disease activity index (CDAI), as it is not reliant on blood data and would also allow us to determine which markers are present in remission. Twenty-two patients under treatment with tocilizumab participated in this study. Effects of treatment as well as the remission rate were measured by CDAI and DAS28 3 months after initiation of treatment. IL-6 and matrix metalloproteinase-3 (MMP-3) levels were measured at the same time. We studied the clinical efficacy of tocilizumab using DAS28 after treatment; remission as measured by DAS28 was 57.1% at 1 year. However, the remission rate as measured by CDAI was only 19.1% at 1 year. CDAI was not only correlated with DAS28, but also other clinical variables, MMP-3, and IL-6. We conclude that CDAI is effective in measuring clinical response to tocilizumab treatment, and that MMP-3 level is as useful as IL-6 level as an indicator.

Abstract
The susceptibility of meniscus allografts to enzymatic degradation may be reduced through tissue stabilization. We have previously reported on an epoxide-based crosslinker, triglycidyl amine (TGA), which can be used alone or with a bisphosphonate (MABP) to stabilize heterograft heart valves and reduce their pathologic calcification. Our objective was to evaluate the effects of TGA and TGA-MABP pretreatment on an orthopedic allograft involving meniscus crosslinking, degradation, calcification, and compressive properties. Ovine menisci treated with TGA or TGA-MABP for up to seven days and glutaraldehyde crosslinked controls were examined in vitro for degree of crosslinking, resistance to degradation by collagenase, and material property changes. Likewise treated menisci were implanted in rats for eight weeks and examined for calcium content and biomechanical changes. TGA treatment for three days significantly reduced collagen loss by 88% and increased thermal denaturation temperatures (Ts) above 80 degrees C versus Ts of 70 degrees C or less for non-crosslinked meniscus. In vitro, TGA and TGA-MABP significantly increased aggregate modulus by 19% and 32% compared to native controls, respectively. TGA decreased permeability by 53% while TGA-MABP increased it by 303%. In vivo, TGA significantly reduced explant calcification by 42% compared to glutaraldehyde, and including MABP reduced it by 90%. Analyses revealed that TGA and TGA-MABP stabilized menisci had significantly lower modulus and permeability values than glutaraldehyde controls by at least 28% and 86%, respectively. It is concluded that TGA crosslinking of meniscus increases resistance to both collagenase degradation and pathologic calcification, while demonstrating comparable or improved biomechanical properties versus glutaraldehyde controls.

Abstract
OBJECTIVE Decoy receptor 3 (DcR3), a newly identified member of the tumor necrosis factor receptor (TNFR) superfamily, is a soluble receptor that binds to members of the TNF family, including FasL, LIGHT, and TNF-like molecule 1A. DcR3 is mostly expressed in tumor cells, and it competitively inhibits binding of TNF to TNFRs. The present study was undertaken to investigate DcR3 expression in fibroblast-like synoviocytes (FLS) from patients with rheumatoid arthritis (RA) and osteoarthritis (OA), and to analyze the effects of DcR3 on Fas-induced apoptosis in RA FLS. METHODS Expression of DcR3 in FLS was measured by reverse transcriptase-polymerase chain reaction (RT-PCR) and Western blotting. FLS were incubated with DcR3-Fc chimera protein or transfected with DcR3 small interfering RNA (siRNA) using the lipofection method, before induction of apoptosis. Apoptosis induced by Fas in FLS was detected with TUNEL staining and Western blotting of caspase 8 and poly(ADP-ribose) polymerase. Finally, FLS were incubated with TNFalpha prior to Fas-induced apoptosis, expression of DcR3 was analyzed by quantitative RT-PCR, and apoptosis was measured. RESULTS DcR3 was expressed in both RA FLS and OA FLS. DcR3-Fc protein inhibited Fas-induced apoptosis in FLS. Down-regulation of DcR3 in FLS by siRNA increased Fas-induced apoptosis. TNFalpha increased DcR3 expression and inhibited Fas-induced apoptosis in RA FLS, but not in OA FLS. CONCLUSION DcR3 expressed in RA FLS is increased by TNFalpha and protects the cells against Fas-induced apoptosis. These findings indicate that DcR3 may be a possible therapeutic target in RA.

Abstract
Matrix metalloproteinase-3 (MMP-3) production increases in rheumatoid arthritis (RA) and has been proposed as a marker of disease activity and joint damage. The aim of this cross-sectional study is to examine the usefulness of serum proMMP-3 as an indicator of disease activity and severity in comparison with erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). Serum proMMP-3 was measured by a quantitative ELISA in 85 RA patients and 70 healthy subjects. Clinical and laboratory measures of disease activity and severity were obtained. Radiological joint damage was assessed by the method of Larsen. Serum proMMP-3 was significantly higher in RA patients than that in the healthy subjects. The active RA patients had significantly higher serum proMMP-3 than the inactive patients. Serum proMMP-3 was significantly correlated with some parameters of disease activity including swollen joints count, proximal interphalangeal joint score, morning stiffness, and Health Assessment Questionnaire; however, ESR and serum CRP were better correlated with all indicators of the disease activity than proMMP-3. The analysis of receiver operating characteristic supported that ESR and CRP had higher performance for reflection of activity compared to proMMP-3. There were no significant associations among Larsen score and proMMP-3, ESR, and CRP. Our results suggest that the cross-sectional measurement of serum proMMP-3 could not give additional information about RA disease activity compared to ESR and CRP, and could not give any information about joint damage.

Abstract
Despite decades of research, only a very limited number of matrix metalloproteinase (MMP) inhibitors have been successful in clinical trials of arthritis. One of the central problems associated with this failure may be our inability to monitor the local activity of proteases in the joints since the integrity of the extracellular matrix results from an equilibrium between noncovalent, 1:1 stoichiometric binding of protease inhibitors to the catalytic site of the activated forms of the enzymes. In the present work, we have measured by flow cytometry the net proteolytic activity in synovial fluids (SF) collected from 95 patients with osteoarthritis and various forms of inflammatory arthritis, including rheumatoid arthritis, spondyloarthropathies, and chronic juvenile arthritis. We found that SF of patients with inflammatory arthritis had significantly higher levels of proteolytic activity than those of osteoarthritis patients. Moreover, the overall activity in inflammatory arthritis patients correlated positively with the number of infiltrated leukocytes and the serum level of C-reactive protein. No such correlations were found in osteoarthritis patients. Members of the MMP family contributed significantly to the proteolytic activity found in SF. Small-molecular-weight MMP inhibitors were indeed effective for inhibiting proteolytic activity in SF, but their effectiveness varied greatly among patients. Interestingly, the contribution of MMPs decreased in patients with very high proteolytic activity, and this was due both to a molar excess of tissue inhibitor of MMP-1 and to an increased contribution of other proteolytic enzymes. These results emphasize the diversity of the MMPs involved in arthritis and, from a clinical perspective, suggest an interesting alternative for testing the potential of new protease inhibitors for the treatment of arthritis.

Abstract
Osteoarthritis (OA) is among the most frequent diseases in the population and a common cause of pain and disability in adults. The principal disease hallmarks for assessment of OA are still clinical observation and radiographic aspects. However, the efficacy of therapeutic interventions is complicated by the time required to observe radiographic signs, useful for both diagnosis and assessment. Thus, laboratory markers have received growing attention in recent years, in an attempt to improve diagnosis, assessment of disease activity and severity, and evaluation of therapeutic effects. Many biomarkers have been proposed, in particular those reflecting cartilage and bone turnover and synovitis. Among these, COMP, antigenic keratan sulphate, hyaluronan, YKL-40, type III collagen N-propeptide, and urinary glucosyl-galactosyl pyridinoline appear to be the most promising. However, serum or urinary determinations of these molecules are difficult to interpret adequately due to their complex metabolism. New ultrasensitive methods for C-reactive protein have improved the usefulness of this marker, especially in the assessment of disease activity. Routine examination of synovial fluid is still essential for diagnosis and includes leukocyte count and crystal detection; specialized testing includes the evaluation of the levels of markers of local inflammation such as metalloproteinases and cytokines, which appear to be crucial to the pathogenesis of OA.

Abstract
The objective of this study has been the well established fact that proinflammatory cytokines and metalloproteinases play a crucial role in the pathogenesis of chronic arthritis as well as the development of pannus, with the eventual erosive changes. Among the proinflammatory cytokines, interleukin-18 (IL-18) has been shown to contribute to the pathogenesis of chronic synovitis by increasing the secretion of interleukin-1beta (IL-1beta) and the tumor necrosis factor-alpha (TNF-alpha) and also stimulating angiogenesis. The aim of this study is to investigate the synovial IL-18, IL-1beta, TNF-alpha and matrix metalloproteinase-3 (MMP-3) levels in patients with Behçet's disease (BD), and compare them with the levels of patients with rheumatoid arthritis (RA) and osteoarthritis (OA). 30 patients with BD, 20 with RA, and 20 with OA were included in the study. The synovial levels of IL-18, IL-1beta, TNF-alpha and MMP-3 were detected using the two-step sandwich ELISA method. The synovial IL-18, TNF-alpha and MMP-3 levels were significantly higher in RA patients than patients with BD (P=0.004, 0.019, 0.025, respectively) and with OA (P=0.004, 0.045, 0.032, respectively). There were no differences, with respect to the cytokine levels, when patients with BD were compared with those with OA. Patients with RA and BD had higher IL-1beta levels than patients with OA (P=0.017, 0.013, respectively). However, no such difference was found for IL-1beta between BD and RA patients. Among patients with RA, positive correlations were found between TNF-alpha and MMP-3 (r=0.683, P=0.001). Our results showed that MMP-3 and proinflammatory cytokines, except IL-1beta, were expressed in relatively small quantities in Behçet's synovitis. Detection of the lower levels of these cytokines and metalloproteinases might explain the non-erosive character of Behçet's arthritis. We suggest that IL-1beta may be involved in the pathogenesis of Behçet's synovitis.

Abstract
OBJECTIVES To measure levels of the collagenases matrix metalloproteinase (MMP)-1 and -13 in the synovial fluid (SF) and serum of patients with juvenile idiopathic arthritis (JIA), and to correlate these measurements with inflammatory activity, levels of the collagenase activator MMP-3 and the tissue inhibitor of metalloproteinases-1 (TIMP-1). METHODS Levels of MMP-1, -3, -13 and TIMP-1 were measured in paired SF and serum from 82 JIA patients using enzyme-linked immunsorbent assay and compared between subtypes and patients of different ages and disease durations. These levels were also correlated to the active joint count (AJC) and standard measures of inflammatory activity and therapeutic response, including erythrocyte sedimentation rate (ESR) and platelet count (PLT). RESULTS MMP-1 was detected in JIA SF and correlated with PLT. MMP-3 levels were high in SF and detectable in serum where they correlated with PLT, ESR and AJC. MMP-13, however, was not detected in SF or serum. No differences were observed between patients grouped by subtype, age or disease duration. MMP-3 contributed the majority of total MMP in SF samples resulting in excess MMP levels over TIMP-1. CONCLUSIONS MMP-1 is up-regulated in SF concordant with inflammatory activity in JIA. This was true for patients in all JIA subtypes and age groups, suggesting that the capability for degradation of type II collagen is present in early disease, and throughout the disease course. MMP-3 may be important in the activation of collagenases and the saturation of exogenous inhibitors. Serum MMP-3 may therefore be a useful, measurable and specific marker of active disease in JIA.

Abstract
OBJECTIVE To assess the relationship between inflammation and joint destruction in rheumatoid arthritis (RA) patients who have not responded clinically to treatment. METHODS Changes from baseline to week 54 in clinical variables and measures of radiographic progression were compared between patients who received infliximab (3 mg/kg or 10 mg/kg every 4 or 8 weeks) plus methotrexate (MTX) and those who received MTX plus placebo in the Anti-Tumor Necrosis Factor Trial in RA with Concomitant Therapy trial. RESULTS At week 54, patients who did not show 20% improvement by American College of Rheumatology criteria (ACR20 nonresponders) while receiving infliximab plus MTX exhibited mild but statistically significant improvement in clinical variables, including the 28-joint Disease Activity Score (DAS28) (P < 0.001), tender joint count (P = 0.014), swollen joint count (P < 0.001), and C-reactive protein (CRP) level (P < 0.001). Whereas the clinical and CRP changes among ACR20 nonresponders to infliximab plus MTX were small and much lower than among ACR20 responders to this treatment, radiographic progression among ACR20 nonresponders to infliximab plus MTX was significantly inhibited (P < 0.001) compared with ACR20 nonresponders to MTX plus placebo. Radiographic progression was much greater in patients receiving MTX plus placebo than in patients receiving infliximab plus MTX, irrespective of ACR response status (mean change in modified Sharp/van der Heijde score 6.0 in ACR20 responders and 7.2 in ACR20 nonresponders in the MTX plus placebo-treated group, versus 0.1 in ACR20 responders and 1.2 in ACR20 nonresponders in the infliximab plus MTX-treated group). Furthermore, among patients who were ACR20 nonresponders through week 54, patients who were DAS nonresponders at weeks 30 and 54, and patients without any improvement in individual clinical variables, those receiving infliximab plus MTX still demonstrated inhibition of structural damage that was statistically significant compared with inhibition in patients who received MTX plus placebo (P < 0.05 to P < 0.001). CONCLUSION Even in patients without clinical improvement, treatment with infliximab plus MTX provided significant benefit with regard to the destructive process, suggesting that in such patients these 2 measures of disease are dissociated.

Abstract
OBJECTIVE To assess the usefulness of measuring serum matrix metalloproteinase 3 (MMP-3) and macrophage colony-stimulating factor (M-CSF) in patients with ankylosing spondylitis (AS). METHODS Serum levels of MMP-3 and M-CSF were measured in AS patients who did and did not receive infliximab treatment. These were compared with those of 28 healthy subjects. RESULTS In the group of AS patients not treated with biologics, both M-CSF and MMP-3 correlated with the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) values, but not with each other. Logistic regression analysis showed that MMP-3 values were high in those with severely active disease. Infusions of infliximab in AS patients led to a significant decrease in the values of the BASDAI as well as the serum MMP-3, but no change in the serum M-CSF values. CONCLUSION MMP-3 and M-CSF are potentially useful markers of AS disease activity.

Abstract
Chlamydophila pneumoniae and Chlamydia trachomatis cause infections of the respiratory or urogenital tract. In addition, both species have been associated with atherosclerosis or reactive arthritis respectively. For these intracellular pathogens the interaction with their host-cells is of particular importance. To get insight into this relationship, we conducted a comparative analysis of the host-cell gene regulation of human epithelial cells during infection with Chlamydia. In a screening of HeLa cells by Affymetrix-microchips, numerous regulated host-genes were identified. A detailed expression profile was obtained for 14 genes by real-time RT-PCR - comparing C. pneumoniae, C. trachomatis and intracellular S. typhimurium. The transcriptional responses induced by C. pneumoniae were similar (but usually smaller) compared to C. trachomatis, some were absent. UV-inactivated bacteria induced no differential gene expression suggesting that pathomechanisms other than those associated with innate immunity play here an important role. The expression pattern induced by Salmonella differed substantially. These genus- or group-specific transcriptional response patterns elicited by viable intracellular pathogens may considerably contribute to the different pathologies encountered in the clinic.

Abstract
Glycoconjugates are a class of macromolecules consisting of different constituents, one of which is sugar moieties. Glycoconjugates comprise the majority of tissue constituents, both intracellular and extracellular. Extracellular glycoconjugates (glycoproteins and proteoglycans) participate in a wide variety of interactions, through which they maintain tissue integrity. Therefore, their analysis or the study of their possible interactions would give evidence for the state of tissues. Since the amounts of some of the extracellular glycoconjugates are usually low or the amounts of tissue to be examined come from biopsies, specific analytical systems are developed for their study, the most familiar being solid phase assays, which have the advantages of analysis of multiple samples on the same time, cheap instrumentation and high specificity.

Abstract
Increasing research interest has focused on arterial calcification in the setting of atherosclerosis. Many features of atherosclerosis-related calcification provide useful clinical information. For example, calcium mineral deposits frequently form in atherosclerotic plaque, and intimal arterial calcification can be used as a surrogate marker for atherosclerosis; also, calcium deposits are readily and noninvasively quantified, which is useful because greater amounts of coronary calcification predict a higher risk of myocardial infarction and death. Several mechanisms leading to calcification associated with atherosclerosis have been proposed; however, no direct testing of proposed mechanisms has yet been reported. Studies in genetically altered animals and in humans have shed light on potential genetic determinants, which in turn could form the basis for a more comprehensive understanding of the factors affecting calcification within plaque and the associated pathobiologic implications. We review proposed molecular and cellular mechanisms of atherosclerosis-associated arterial calcification, summarize genetic influences, and suggest areas in which further investigation is needed. Understanding the molecular and genetic determinants of specific structural plaque components such as calcification can provide a solid foundation for the development of novel therapeutic approaches to favorably alter plaque structure and minimize vulnerability to arterial rupture.

Abstract
OBJECTIVE To analyse the relation between systemic levels of pro-MMP-3, -8, and -9 matrix metalloproteinase (MMP) activity in alpha(2) macroglobulin (alpha(2)M)/MMP complexes and the progression of joint destruction in patients with recent onset rheumatoid arthritis (RA). METHODS 109 patients with RA of recent onset were entered into this longitudinal study. Patients were followed up for two years; clinical data, blood samples, and radiographs were obtained at baseline and at 1 and 2 years. Serum levels of MMPs were measured by sandwich ELISA and MMP activity assays. RESULTS During the two years joint damage progressed from 0 to 10 (median Sharp score, p<0.001). Stable levels of pro-MMP-3 and a significant decrease in the levels of pro-MMP-8 and -9 and alpha(2)M/MMP complexes were seen throughout the two years. Regression analysis showed that serum pro-MMP-3 levels at disease onset were independently associated with the progression of joint damage (B=0.7, 95% CI 0.3 to 1.1, p=0.001). Based on the rate of joint destruction, patients were divided into two subgroups: patients with mild and severe joint damage progression. The pro-MMP-3 levels were significantly higher in the group with severe compared with mild disease at all times. Levels of pro-MMP-8 and -9 were decreased in both groups, whereas alpha(2)M/MMP complex levels decreased in the group with mild disease only. CONCLUSION Serum levels of the MMPs studied are associated with disease activity, but serum pro-MMP-3 levels at the onset of disease are also predictive of joint damage progression.

Abstract
Progress in the knowledge of pathogenic mechanisms and a better definition of the disease, together with the availability of new technologies, have recently improved the value of laboratory investigations in osteoarthritis (OA). The main objectives of these findings are early diagnosis, assessment of disease activity and severity, and evaluation of therapeutic effects. In this context, biochemical markers are potentially useful, as they are non-invasive and non-expansive. However, among the numerous substances increasingly proposed for these purposes, very few may be considered as true disease markers in OA; COMP, antigenic keratan sulphate, hyaluronic acid, YKL-40, type III collagen N-propeptide and urinary glucosyl-galactosyl pyridinoline seem to be the most promising. However, serum or urinary determinations of these molecules are difficult to interpret adequately, due to their complex metabolism. Careful analysis of synovial fluid, mainly directed to leukocyte count and crystal detection, is still essential for diagnosis, but also for the evaluation of the levels of important markers of local inflammation, such as metalloproteinases and cytokines, which seem to be crucial in the pathogenesis of OA.

Abstract
OBJECTIVE Since the development of posttraumatic osteoarthritis (OA) is a relatively slow process, estimation of OA risk would be of value with regard to chondroprotective measures and medication. In this study we investigated the significance of pro-matrixmetalloproteinase-3 (proMMP-3) for this purpose. DESIGN Synovial fluid (SF) and serum samples were collected from 259 patients of our trauma clinic at the time of arthroscopy. The extent of cartilage damage was assessed according to the Outerbridge-score. ProMMP-3 levels in SF and serum were determined by enzyme-linked immunosorbent assay (ELISA) using a monoclonal antibody. Additionally we determined SF and serum levels of total MMP-3 and COMP levels as well as TIMP-1 and -2 concentrations in 40 randomly selected patients by ELISA. RESULTS Serum proMMP-3 levels of the total cohort were markedly increased compared to healthy controls (P<0.007). The comparison of serum and SF lavage proMMP-3 concentrations showed a significant correlation (r(s)=0.41, P<0.0001), however, only 26% of the investigated samples were increased above normal ranges. The grade of cartilage damage did not correlate with enzyme concentration neither in patients' serum nor in SF samples. ProMMP-3 SF concentration was increased early after trauma. Furthermore, proMMP-3 correlated significantly with total MMP-3 serum and SF levels as well as COMP SF levels. CONCLUSIONS The measurement of proMMP-3 in serum or SF did not reflect the present cartilage damage and thus appears to have only minor potential for clinical use, but it should be considered for longitudinal studies, since it may reflect a risk for cartilage degradation in a subset of patients.

Abstract
The purpose of this study was to investigate whether synovial fluid levels of matrix metalloprotease-3 (MMP-3) and tissue inhibitor of metalloprotease-1 (TIMP-1) are specifically elevated in canine rheumatoid arthritis (CRA) compared to osteoarthritic joint disorders and if these markers are correlated with a specific pattern of cytokine mRNA expression. Synovial fluid samples of 17 dogs with CRA were analysed for MMP-3 and TIMP-1 by two canine sandwich ELISA (enzyme-linked immunosorbent assay) systems. The synovial mRNA content of tumor necrosis factor-alpha (TNF-alpha), interleukin-1 (IL-1), interleukin-6 (IL-6), interleukin-12 (IL-12), transforming growth factor-beta (TGF-beta), and interferon-gamma (IFN-gamma) was determined by RT-PCR (reverse transcription-polymerase chain reaction). Dogs with osteoarthritis (n = 50) caused by anterior cruciate ligament rupture (ACLR) were used as controls. A significant rise of MMP-3 was found in the synovial fluid of joints with CRA that could not be balanced by sufficient amounts of TIMP-1. The 30-fold surplus of MMP-3 over TIMP-1 was strongly correlated with the synovial mRNA content of IL-1, IL-12 and TGF-beta. Our results point to the potential use of the synovial levels of MMP-3 as a marker for RA in dogs.

Abstract
OBJECTIVE An imbalance in the matrix metalloproteinase:tissue inhibitor of metalloproteinases (MMP:TIMP) ratio in favor of MMP appears to be an important determinant of tissue damage in arthritis. We undertook this study to explore whether reversal of this imbalance in favor of TIMP would alter this process and to examine the mechanism of this alteration. METHODS We administered human TIMP-4 by electroporation-mediated intramuscular injection of naked DNA using the rat adjuvant-induced arthritis (AIA) model. RESULTS Intramuscular naked TIMP-4 gene administration resulted in high circulating TIMP-4 levels and completely abolished arthritis development in the rat AIA model. This inhibition was associated with significantly decreased MMP activity in the joint tissue as well as with significantly decreased serum and tissue tumor necrosis factor alpha levels and serum interleukin-1alpha levels compared with animals with arthritis. The mutation of cysteine at position 1 of TIMP-4 failed to block the development of AIA. CONCLUSION Our data indicate that TIMP-4 is a potent antiinflammatory agent, and that its antiarthritis function may be mediated by MMPs. Arthritis-inhibiting effects of TIMP-4 may suggest a unique application of this gene therapy method for arthritis.

Abstract
OBJECTIVE To explore the levels of matrix metalloprotease-3 (MMP-3), tissue inhibitor of metalloproteases-1 (TIMP-1), 5D4 keratan sulfate, and two 3B3 chondroitin-sulfate epitopes in several canine osteoarthritic and inflammatory arthropathies. METHODS Blood and synovial fluid were obtained from 103 dogs with rupture of the anterior cruciate ligament (ACLR), osteochondritis dissecans (OCD), fragmented coronoid process (FPC), patella luxation (PL), hip dysplasia (HD) or infectious arthritis. Dogs with non-musculosceletal disorders were used as controls. The biomarkers were measured by immunoassays. RESULTS Median levels of synovial MMP-3, TIMP-1 and molar ratios of MMP/TIMP-1 were significantly higher in the arthritis than in the control group. The release of 5D4 keratan sulfate epitope and serum 3B3 neoepitope was reduced in arthritis patients. Increases in synovial TIMP-1 in OA were less pronounced and the molar ratio of MMP-3/TIMP-1 remained far below 1.0, demonstrating a surplus of the protease inhibitor. In osteoarthritic patients median levels of synovial 5D4 keratan sulfate were up-regulated after ACLR and PL and were inversely correlated with increasing duration of lameness. Serum TIMP-1 levels were significantly reduced in the joint disorder group when compared with the control group. CONCLUSION Our observations present the TIMP-1 serum level as a potential marker for the detection of degenerative changes in cartilage and also indicate that in canine OA, the MMP-3 mediated matrix destruction is not of major importance. However MMP-3 seems to be a sensitive marker for the local inflammation in canine arthritis.

Abstract
OBJECTIVE To determine matrix metalloproteinase-3 (MMP-3) serum levels in patients with rheumatic diseases and to study the relation between MMP-3 and C reactive protein (CRP) levels. METHODS MMP-3 serum levels were determined by enzyme linked immunosorbent assay (ELISA) in (a) patients with active inflammatory rheumatic diseases: rheumatoid arthritis (RA), psoriatic arthritis, polymyalgia rheumatica, acute crystal arthritis, and ankylosing spondylitis; (b) patients with active inflammatory systemic diseases: cutaneo-articular or renal systemic lupus erythematosus (SLE), systemic sclerosis, and vasculitides; (c) patients with non-inflammatory rheumatic diseases: osteoarthritis and fibromyalgia; (d) critically ill patients without rheumatic diseases, representing an acute inflammatory control group; (e) healthy controls. RESULTS MMP-3 serum levels were significantly increased in patients with active RA, psoriatic arthritis, and polymyalgia rheumatica, whether treated or not by corticosteroids, and in female patients with acute crystal arthritis. MMP-3 serum levels were normal in steroid-free patients with active cutaneo-articular or renal SLE, systemic sclerosis, and vasculitides but were significantly increased in steroid treated patients. MMP-3 levels were normal in fibromyalgia, osteoarthritis, ankylosing spondylitis, and acute inflammatory controls. MMP-3 was significantly correlated with CRP in RA (r=0.5, p=0.0004) but not in any of the other disease groups. CONCLUSIONS MMP-3 serum levels are increased in inflammatory rheumatic diseases characterised by joint synovitis, such as RA, polymyalgia rheumatica, psoriatic arthritis, and acute crystal arthritis-that is, whether the diseases are acute or chronic, erosive or not. They are normal in SLE, systemic sclerosis, and vasculitides as well as in non-rheumatic inflammatory controls, but are significantly increased by steroids. These data strongly suggest that serum MMP-3 reflects synovial inflammation.

Abstract
Synovial fluid fills the spaces in the joint cavities. Many diseases can affect the joints and frequently only a direct examination of the tissue or synovial fluid will yield the correct diagnosis. The article presents the basis of the synovial fluid analysis and a relevant decision-making scheme. The reliability and applicability of synovial fluid tests are commented upon. The synovial fluid analysis undoubtedly plays an important role in the management of patients with joint diseases. Due to a lack of interlaboratory comparisons, and therefore expert opinions on the interpretation of results, this knowledge and the acquisition of relevant experience should be encouraged to enable evaluation of the clinical applicability of recent discoveries in synovial fluid pathology.

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.
