Serum response elements activate and cAMP responsive elements inhibit expression of transcription factor Egr-1 in synovial fibroblasts of rheumatoid arthritis patients. (2/1952)

Analyzing the induction kinetics and promoter elements regulating the expression of the transcription factor Egr-1, we found elevated levels of Egr-1-encoding mRNA in synovial fibroblasts of rheumatoid arthritis (RA) patients when compared to controls. By contrast, synovial lymphocytes and macrophages do not show an elevated Egr-1 transcription. Therefore, the overexpression of Egr-1 may serve as a diagnostic marker to characterize synovial fibroblasts of RA patients. To study the regulatory mechanisms controlling Egr-1 expression we analyzed the function of transcription factor binding sites located in the Egr-1 promoter. Individual transcription factor binding sites within the Egr-1 promoter were specifically mutated and Egr-1 promoter activity was tested using reporter gene constructs. Our experiments demonstrate that serum response elements are the main positive regulators and binding to a cAMP responsive element represents the major negative regulator for Egr-1 expression in synovial fibroblasts. In addition, we functionally defined a new element, which was not yet described in the human Egr-1 promoter and which serves as a second negative regulatory element for Egr-1 expression. Therefore increased serum response factor activity or failure of Egr-1 repressing signals may account for Egr-1 overexpression in RA synovial fibroblasts.  (+info)

Modulation of acute and chronic inflammatory processes by cacospongionolide B, a novel inhibitor of human synovial phospholipase A2. (3/1952)

1. Cacospongionolide B is a novel marine metabolite isolated from the sponge Fasciospongia cavernosa. In in vitro studies, this compound inhibited phospholipase A2 (PLA2), showing selectivity for secretory PLA2 (sPLA2) versus cytosolic PLA2 (cPLA2), and its potency on the human synovial enzyme (group II) was similar to that of manoalide. 2. This activity was confirmed in vivo in the 8 h zymosan-injected rat air pouch, on the secretory enzyme accumulating in the pouch exudate. Cacospongionolide B, that is bioavailable when is given orally, reduced the elevated levels of sPLA2 present in paw homogenates of rats with adjuvant arthritis. 3. This marine metabolite showed topical anti-inflammatory activity on the mouse ear oedema induced by 12-O-tetradecanoylphorbol acetate (TPA) and decreased carrageenin paw oedema in mice after oral administration of 5, 10 or 20 mg kg(-1). 4. In the mouse air pouch injected with zymosan, cacospongionolide B administered into the pouch, induced a dose-dependent reduction in the levels of eicosanoids and tumour necrosis factor alpha (TNFalpha) in the exudates 4 h after the stimulus. It also had a weak effect on cell migration. 5. The inflammatory response of adjuvant arthritis was reduced by cacospongionolide B, which did not significantly affect eicosanoid levels in serum, paw or stomach homogenates and did not induce toxic effects. 6 Cacospongionolide B is a new inhibitor of sPLA2 in vitro and in vivo, with anti-inflammatory properties in acute and chronic inflammation. This marine metabolite was active after oral administration and able to modify TNFalpha levels, and may offer an interesting approach in the search for new anti-inflammatory agents.  (+info)

Cytokine levels in synovial fluid from hips with well-functioning or loose prostheses. (4/1952)

We analysed synovial fluid from 88 hips, 38 with osteoarthritis and 12 with well-functioning and 38 with loose hip prostheses. The levels of TNF-alpha, IL-1beta (71 hips) and IL-6 (45 hips) were measured using the ELISA technique. Joints with well-functioning or loose prostheses had significantly increased levels of TNF-alpha compared with those with osteoarthritis. Hips with aseptic loosening also had higher levels of IL-1beta but not of IL-6 compared with those without an implant. The levels of TNF-alpha and IL-1beta did not differ between hips with stable and loose prostheses. Higher levels of TNF-alpha were found in hips with bone resorption of type II and type III (Gustilo-Pasternak) compared with those with type-I loosening. The level of cytokines in joint fluid was not influenced by the time in situ of the implants or the age, gender or area of the osteolysis as measured on conventional radiographs. Our findings support the theory that macrophages in the joint capsule increase the production of TNF-alpha at an early phase probably because of particle load and in the absence of clinical loosening. Since TNF-alpha has an important role in the osteolytic process, the interfaces should be protected from penetration of joint fluid.  (+info)

Synovial fluid transforming growth factor beta inhibits dendritic cell-T lymphocyte interactions in patients with chronic arthritis. (5/1952)

OBJECTIVE: To examine whether rheumatoid synovial fluid (SF) inhibits dendritic cell (DC) expression of the CD80 and CD86 costimulator molecules and contributes to SF T lymphocyte hyporesponsiveness. METHODS: Cell-free rheumatoid SF was tested for its effect on DC-stimulated autologous/allogeneic mixed lymphocyte reactions and for its effect on DC surface antigen expression, as assessed by flow cytometry. Blocking monoclonal antibodies were used to identify the SF cytokines that inhibited DC-T lymphocyte interactions. RESULTS: Low concentrations of SF (2.5%) could inhibit DC-mediated autologous and allogeneic T lymphocyte proliferation. This inhibitory effect could be reversed by neutralizing transforming growth factor beta (TGFbeta) and interleukin-2 (IL-2), but not by IL-12, in the SF. Hyaluronic acid, IL-6, IL-10, and tumor necrosis factor alpha were not associated with SF inhibition. In vitro culture alone and crosslinking with the CD40 ligand up-regulated DC CD80/CD86 expression and costimulator function, and this was not affected by inclusion of SF. In the presence of SF, DC clustered with autologous T lymphocytes showed decreased CD80 and CD86 expression, and variable CD80/CD86 decreases were observed on DC clustered with allogeneic T lymphocytes. CONCLUSIONS: TGFbeta in SF appears to suppress T lymphocyte function, which may affect both signaling to DC and the induction of DC costimulator function.  (+info)

Changes in joint cartilage aggrecan after knee injury and in osteoarthritis. (6/1952)

OBJECTIVE: To determine the concentrations of aggrecan fragments in synovial fluid from patients with knee joint injury, osteoarthritis (OA), or acute pyrophosphate arthritis (PPA; pseudogout), and to test their relative reactivity with the 846 epitope, a putative marker of cartilage aggrecan synthesis. METHODS: Samples of knee joint fluid from 385 patients and 9 healthy-knee volunteers were obtained in a cross-sectional study. Study groups were acute PPA/ pseudogout (n = 60), anterior cruciate ligament (ACL) rupture (n = 159), meniscus lesion (n = 129), and primary knee OA (n = 37). The 846 epitope on aggrecan was assayed by competitive solution-phase radioimmunoassay. Aggrecan fragments were assayed by enzyme-linked immunosorbent assay using a monoclonal antibody (1-F21). Cartilage oligomeric matrix protein (COMP), C-propeptide of type II collagen (CPII), bone sialoprotein, matrix metalloproteinases 1 and 3, and tissue inhibitor of metalloproteinases 1 were previously quantified by immunoassays. RESULTS: Reactivity of the 846 epitope was increased in all study groups compared with the reference group, and was highest in patients with primary OA. The median levels (in microg fetal aggrecan equivalents/ml) of the epitope were 0.28 (range 0.24-0.47) in the reference group, 0.48 (range 0.26-1.32) in PPA/pseudogout, 0.61 (range 0.12-2.87) in ACL rupture, 0.53 (range 0.22-3.02) in meniscus lesion, and 0.68 (range 0.31-4.31) in primary OA. The 846 epitope reactivity per microg aggrecan fragments in the joint fluid was higher in late-stage OA than in early-stage OA. Epitope 846 reactivity correlated positively with several markers of matrix turnover, particularly with COMP (r(s) = 0.421) and CPII (r(s) = 0.307). CONCLUSION: The observed differences in 846 epitope reactivity in synovial fluid, and its concentration in relation to aggrecan and other markers of matrix turnover, were consistent with marked ongoing changes in aggrecan turnover after joint injury and in the development of OA. OA is thus a disease characterized by dynamic changes in tissue macromolecule turnover, which is reflected by measurable changes in aggrecan epitopes in the synovial fluid.  (+info)

Diacerhein treatment reduces the severity of osteoarthritis in the canine cruciate-deficiency model of osteoarthritis. (7/1952)

OBJECTIVE: To determine if diacerhein protects against the early stages of joint damage in a canine model of osteoarthritis (OA). METHODS: OA was induced in 20 adult mongrel dogs by transection of the anterior cruciate ligament of the left knee. Beginning the day after surgery, dogs in the active treatment group were dosed twice a day with capsules of diacerhein, providing a total daily dose of 40 mg/kg, for 32 weeks. Dogs in the control group received placebo capsules on the same schedule. Pathology in the unstable knee was assessed arthroscopically 16 weeks after surgery and by direct observation when the dogs were killed 32 weeks after surgery. The severity of gross joint pathology was recorded, and samples of the medial femoral condyle cartilage and the synovial tissue adjacent to the central portion of the medial meniscus were collected for histologic evaluation. Water content and uronic acid concentration of the articular cartilage from the femoral condyle were determined, and collagenolytic activity in extracts of cartilage pooled from the medial and lateral tibial plateaus was assayed against 14C-labeled collagen fibers. RESULTS: Diacerhein treatment slowed the progression of OA, as measured by grading of gross changes in the unstable knee at arthroscopy 16 weeks after cruciate ligament transection (P = 0.04) and at the time the animals were killed, 32 weeks after surgery (P = 0.05). However, 32 weeks after ACL transection, the mean proteoglycan concentration and water content of the OA cartilage and the level of collagenolytic activity in extracts of the cartilage were not significantly different in the diacerhein treatment group than in the placebo treatment group. CONCLUSION: Diacerhein treatment significantly reduced the severity of morphologic changes of OA compared with placebo. These findings support the view that diacerhein may be a disease-modifying drug for OA.  (+info)

Results Our data show that in T cells isolated from healthy controls, Rap1 activation was sensitive to redox balance alterations. Upregulation of intracellular GSH by incubation with 10 mM NAC for 48 h resulted in diminished Rap1 activation, while depletion of GSH by pre-incubation with 200mM BSO resulted in increased Rap1 activation. We also observed that treatment of T cells with H2O2 led to the rapid activation of Rap1.. Despite an environment of oxidative stress in the inflamed joints of RA patients, we found that in SF T cells Rap1 was present in its inactive GDP-bound state. Furthermore, while the PB T cells of RA patients could be normally activated, Rap1 remained inactive in SF T cells upon stimulation. The defective Rap1 activation was not due to increased levels of the Rap1 GTPase activating proteins RapGAP or spa1. While restoration of the intracellular redox balance seems to reverse the hypo responsiveness of the SF T cells, this had no effect on the defective rap1 activation. ...
OBJECTIVE: To use gene expression profiles of spondyloarthropathy (SpA) synovial fluid mononuclear cells (SFMC) to determine if there are transcripts that support the unfolded protein response (UPR) hypothesis, and to identify which cytokines/chemokines are being expressed and which cell fractions are involved. METHODS: Gene expression profiles were generated by microarray screening of SFMC of 5 patients with SpA, 5 patients with rheumatoid arthritis (RA), and peripheral blood mononuclear cells (PBMC) of 6 controls. Results were validated by reverse transcription polymerase chain reaction using samples from a larger panel of subjects. RESULTS: The repertoires of proinflammatory cytokines/chemokines expressed by SpA and RA SFMC were very similar: monocyte chemotractant protein 1 (MCP-1), interleukin 8 (IL-8), IL-1beta, endothelial-monocyte activating polypeptide II, interferon-gamma, and tumor necrosis factor-alpha. MCP-1 was highly expressed in SpA SFMC. There was enhanced expression of ...

As we have previously shown, SF macrophages express increased levels of CD40 [28]. Synovial T cells express CD154 [32, 33], indicating that synovial T cells can activate antigen-presenting cells via CD40. In the present study, we show that SF macrophages produce IL-12p40 but not the IL-12p70 heterodimer after CD40 ligation. Our data support the idea that the production of IL-12p40 and p70 are independently regulated and indicate that despite the augmented CD40 expression, triggering of CD40 does not induce IL-12p70 production in SF macrophages. We also provide evidence that CD40 ligation upregulates the transcription of p40 more consistently and to a higher level than p35 transcription, suggesting that the lack of p35 transcription limits p70 protein production. We also show that DCs derived from SF macrophages produce high levels of IL-12p70. These data suggest that SF macrophages contain the progenitors of myeloid DCs that are the main producers of IL-12p70 in the synovium. This is in line ...
IL-17 is a major proinflammatory cytokine secreted by activated T-lymphocytes that accumulates in the inflamed joints of rheumatoid arthritis (RA) patients. Additional IL-17-related molecules and their receptors have been discovered and may also contribute to RA pathogenesis. We examined the expression of the prototypic IL-17 (IL-17A) and its homologs, IL-17B-F, by RT-PCR analyses of synovial fluid mononuclear cells (SFMCs) and peripheral blood mononuclear cells (PBMCs) from RA patients. We also tested for induction of the IL-17 receptor homologs upon stimulation of the fibroblast-like synoviocytes (FLSs) of RA patients with IL-17. The patients SFMCs expressed IL-17C, E and F in addition to IL-17A. As in the case of IL-17, IL-15 appears to be the major inducer of these homologs in RA SFMCs. We detected transcripts of IL-17R, as well as those of IL-17RB, C and D, in the FLSs of RA patients. Whereas IL-17R expression increased upon in vitro stimulation with IL-17, expression of IL-17RB, C and D ...

Nongonococcal infectious arthritis is an acute or subacute illness with potentially significant morbidity and mortality. It can be caused by bacteria, mycobacteria, or fungi.
In rheumatoid arthritis (RA), T cells isolated from the synovial fluid (SF) show impaired responses to mitogenic stimulation compared with T cells from the peripheral blood (PB). Here it is reported that hyporesponsiveness of SF T cells correlated with a significant decrease in the levels of the intracellular redox-regulating agent glutathione (GSH). GSH was decreased in both CD4+ (p = 0.0022) and CD8+ (p = 0.0010) SF T cell subsets compared with PB CD4+ and CD8+ T cells in RA patients. Levels of thioredoxin (TRX), another key redox mediator, previously found to be secreted under conditions of oxidative stress, were found to be significantly increased in SF compared with plasma samples of RA patients (p = 0.005). Increased levels of TRX in the SF of inflamed joints was found to be associated with RA when compared with other arthritides (p = 0.007). Restoration of GSH levels in SF T cells with N-acetyl-L-cysteine (NAC), enhanced mitogenic induced proliferative responses and IL-2 production. ...
Our study focused on elucidating the in vitro effects of HA of differing molecular weights on fibroblast-like synovial cells in the face of a LPS challenge. Notably, the higher molecular weight HA product significantly reduced the morphologic change of synovial cells in vitro following a 2-hour challenge with 20 ng/ml LPS when compared with the lower molecular weight HA product (Table 1 and Figure 1). Higher molecular weight HA may preserve normal/healthy cell morphology due to a number of factors. Our results suggested that one probable mechanism to explain this finding is related to the ability of higher molecular weight HA to maintain hysteresis, compliance, and fluid exchange by reducing or dissipating stress associated with mechanical forces [42]. This facility may have enabled the fibroblast-like synovial cells in group 4 to resist contraction from the cell culture flasks when reacting to the cellular effects induced by LPS. It is also possible that pretreatment with the higher molecular ...
Infection occurs through the blood and lymph circulation. In the pathological process involved, usually large joints of the lower extremities. As a consequence there is septic arthritis knee, hip or ankle joint. The disease at a high temperature, the baby acute pain in the joints, which increases with movement. It is for this reason the child refuses to move, then to speak of «false paralysis». At high temperature there may be nausea and vomiting, drowsiness, or, conversely, hyperactivity of the child.. At first suspected septic arthritis should immediately consult the doctor and undergo appropriate testing. May need biopsy or synovial fluid analysis, ultrasonography and other clinical tests.. Important differential diagnosis, as infectious arthritis of different etiology has similar symptoms. It is especially difficult to diagnose an infant that is not walking, and therefore to evaluate the functional state of the joints is quite difficult. The correct diagnosis - a task that only an ...
To examine the accuracy of dual-energy computed tomography (DECT) vs ultrasound or their combination for the diagnosis of gout.Using prospectively collected data from an outpatient rheumatology clinic at a tertiary-care hospital, we examined the diagnostic accuracy of either modality alone or their combination, by anatomical site (feet/ankles and/or knees), for the diagnosis of gout. We used two standards: (1) demonstration of monosodium urate crystals in synovial fluid (gold), and (2) modified (excluding DECT and ultrasound) 2015 ACR-EULAR gout classification criteria (silver).Of the 147 patients who provided data, 48 (33%) had synovial fluid analysis performed (38 were MSU-crystal positive) and mean symptom duration was 9.2 years. 100 (68%) patients met the silver standard.

The present disclosure relates to oligodeoxynucleotides that suppress an immune response. Methods are disclosed for preventing or treating inflammatory arthropathies by administering a therapeutically effective amount of a suppressive oligodeoxynucleotide.
The present results demonstrate, for the first time, that human SF express functional LXA4R and that antiinflammatory actions arise by its interaction with the cognate endogenous ligand LXA4. Namely, LXA4 was found to inhibit IL-1β-induced MMP-3 expression, IL-6 and IL-8 release while stimulating the synthesis of TIMP proteins. Synthesis of these mediators by SF has been recognized as a pivotal step in the pathophysiology of inflammatory arthritides (3, 26). The ability of LXA4 to modify these processes was tested after triggering SF cell activation by use of IL-1β, a typical proinflammatory cytokine. Results indicate that SF expression of LXA4R mRNA, and presumably protein expression, is up-regulated up to ∼5-fold upon stimulation with IL-1β when compared with control cells (Fig. 1⇑). Because several LXA4 antiinflammatory activities are mediated via signaling pathways involving LXA4R cell surface expression (17, 22), the noted IL-1β up-regulation suggests that this cytokine is ...

Polymerase chain reaction (PCR) technology was employed to examine peripheral blood and synovial T cells in patients with rheumatoid arthritis (RA) for biased utilization of T cell receptor (TCR) variable region (V) genes. Oligonucleotide primers specific for individual TCR V beta gene families were used to amplify TCR gene products in a semiquantitative assay of their relative utilization in unselected T cell populations. Mean V beta expression in 24 RA peripheral blood samples was very similar to that in a panel of 15 normal subjects, except for a slight decrease in V beta 13.2 expression. V beta utilization in 8 RA synovial tissue samples and 13 synovial fluid samples was compared to simultaneously obtained blood samples. Although heterogeneous patterns of skewed V beta utilization were observed, several significant trends emerged. By a number of approaches to data analysis, a statistically significant increase in expression of V beta 6 and V beta 15 in synovial T cells was documented. In ...
People with gout are at increased risk of developing kidney stones. The kidney stones composed of uric acid that are part of gout often contain calcium crystals as well.. The best way to diagnose gout is to examine synovial fluid from an affected joint under a microscope to look for urate crystals. The sample can be obtained from the typhus as well. Sometimes, the synovial fluid analysis is not possible to obtain. The diagnosis is made then based on the typical clinical picture and presence of the high uric acid level in the blood samples. Rarely, patients have normal levels of uric acid during gout attacks.. Management of acute gout attacks involves the use of medications to decrease the inflammation (NSAIDs, colchicine, and prednisone). When attack is resolved physicians use medications to decrease uric acid levels (allopurinol, uloric). They are continued indefinitely. Urate-lowering medications decrease uric acid levels in one of three ways: they increase uric acid elimination by the ...
Type II collagen (CII) posttranslationally modified by reactive oxygen species (ROS-CII) that are present in the inflamed joint is an autoantigen in rheumatoid arthritis (RA). The aim of this study was to investigate the potential use of anti-ROS-CII autoantibodies as a biomarker of RA.CII was exposed to oxidants that are present in the rheumatoid joint. Autoreactivity to ROS-CII was assessed by enzyme-linked immunosorbent assays in synovial fluid (SF) and serum samples obtained from patients during various phases of RA. This group included disease-modifying antirheumatic drug (DMARD)-naive patients with early RA (n = 85 serum samples) and patients with established RA (n = 80 serum and 50 SF samples), who were categorized as either DMARD responders or DMARD nonresponders. Control subjects included anti-citrullinated protein antibody (ACPA)-positive patients with arthralgia (n = 58 serum samples), patients with osteoarthritis (OA; n = 49 serum and 52 SF samples), and healthy individuals (n = 51 serum

This study focuses upon three chemokines, namely CCL5, CXCL10 and CCL3, which are potential novel therapeutic targets in arthritis. The aim of the study was to analyse the expression and production of these three chemokines within the joints of children with juvenile idiopathic arthritis (JIA) of the oligoarticular and polyarticular subtypes. All three of these chemokines are highly expressed at the level of mRNA, with the most significant increase in mRNA levels being demonstrated for CCL5 when compared with matched peripheral blood samples and controls. We show that high levels of all three chemokines are present in synovial fluid of children with JIA. We investigate the major source of CCL5 from inflammatory synovial cells, which we show to be CD8+ T cells. This CD8+ synovial T cell population has an unexpected phenotype that has not been described previously, being CCR7- yet predominantly CD28+ and CD45RA-. These cells contain high levels of stored intracellular CCL5, and rapid release of CCL5 takes

A system for injection of a fluid into a body includes: a source of a first fluid, a source of a second fluid; the first fluid being less toxic than the second fluid; at least one pressurizing system in operative connection with the source of the first fluid and with the source of the second fluid; at least one controller in operative connection with the pressurizing system; and at least a first sensor in communicative connection with the controller. The first sensor is adapted to transmit a signal of a detected change in fluid level in tissue indicative of extravasation to the controller. The controller is adapted to cause injection of the first fluid into the body to determine if extravasation of the first fluid occurs using the sensor in an administration phase before injection of the second fluid.
