Abstract
OBJECTIVE To define variations in the cellular infiltrate and in the expression of monokines in synovial tissue (ST) from rheumatoid arthritis (RA) patients with different durations of disease and different levels of disease activity. METHODS The immunohistologic features of synovial biopsy specimens from 31 patients with early RA (< 1 year) and 35 patients with longstanding RA (> 5 years) were compared. The possible associations between these features and local disease activity, as measured by the score for pain in the biopsied knee joint were also evaluated. RESULTS The immunohistologic features were not dependent on disease duration. We found a positive correlation between the scores for knee pain and the semiquantitative scores for the number of macrophages, as well as the expression of interleukin-6 and tumor necrosis factor alpha, whereas the correlation with the scores for CD4+ T cells was negative. Multivariate analysis showed that these correlations were highly statistically significant (P < 0.003). CONCLUSION The results do not support the view that inflammatory mechanisms in the synovial tissues of RA patients differ between early and late stages of the disease. The findings presented here are consistent with the concept that early RA is the result of a synovitis process of longer duration and that macrophage-derived cytokines play an important role in maintaining the clinical signs of inflammation.

Abstract
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. Collectively, these data impute an important role to an altered redox state in the hyporesponsiveness of joint T cells in patients with RA.

Abstract
To gain insight into the nature of the immune response with respect to accumulation and composition of the T-cell receptor (TCR) repertoire in synovial tissue in rheumatoid arthritis (RA), we have determined the nucleotide sequence of TCRBV regions transcribed by T lymphocytes derived from synovial tissue. Synovial tissue was obtained by needle biopsies from three different sites of the same joint in two early RA patients. We found that the TCRBV region repertoire among synovial tissue-infiltrating mononuclear cells was heterogeneous when the different biopsies taken from each patient were compared. However, DNA sequence analysis of TCRBV rearrangements of synovial T lymphocytes showed conserved amino acid usage profiles in the CDR3 domains of different TCRBV regions, which exhibited an individual specific character. These CDR3 motifs were not present in paired samples of peripheral blood. The existence of homologous CDR3 amino acid profiles within the TCRBV regions derived from synovial tissue is indicative of an antigen-driven immune response.

Abstract
Differentiation of CD4+ T-cells is reflected by the change from the CD45RA+CD27+ phenotype via CD45RO+CD27+ to the CD45RO+CD27- phenotype. To provide insight into the migration and activation of T-cells at the site of inflammation in rheumatoid arthritis (RA), CD27 expression by T-cells in peripheral blood (PB), synovial fluid (SF), and synovial tissue (ST) as well as the levels of the soluble form of CD27 (sCD27) in plasma and SF were studied in patients with RA. Since CD4+CD27+ T-cells are involved in providing helper activity for B-cells, we also investigated the levels of rheumatoid factors in serum and SF in relation to CD27 expression. The mean level of sCD27, which is produced by CD27+ cells, and the mean percentage of CD27 T-cells within the CD4+CD45RA- subset were higher in SF than in PB. SF sCD27 levels were higher in the patients with RA than in the patients with osteoarthritis, who served as controls. In ST infiltration by CD4+CD45RO+CD27+ T-cells, could be demonstrated in the rheumatoid perivascular lymphocytic aggregates with a relative increase in the percentage of CD27- T-cells in the diffuse lymphocytic infiltrate. The sCD27 levels and the percentages of CD4+CD27+ cells in SF correlated positively with the levels of rheumatoid factors in serum and SF. The findings presented in this study suggest a continuous influx of preactivated CD4+CD45RO+CD27+ cells from the PB into the rheumatoid ST and further activation and differentiation to CD4+CD45RO+CD27- cells in situ, followed by migration to the SF. These activated T-cells are likely to play a role in synovial inflammation.

Abstract
Matrix metalloproteinases (MMPs) are involved in physiological tissue remodeling and pathological conditions like tumour metastasis and joint destruction. Until now, no convenient and sensitive MMP-activity assay in crude media like synovial fluid has been available. Therefore, the highly soluble fluorogenic substrate TNO211 (Dabcyl-Gaba-Pro-Gln-Gly-Leu-Glu(EDANS)-Ala-Lys-NH2), containing the MMP cleavable Gly-Leu bond and EDANS/Dabcyl as fluorophore/quencer combination, was synthesized and characterized as an MMP specific substrate. We show that the fluorogenic assay using TNO211 is sensitive and can detect MMP activity in culture medium from endothelial cells and untreated synovial fluid (SF) from RA and OA patients, and control subjects. MMP activity in SF significantly increased in the order C < OA < RA, thus the frequent use of OA samples as control in studies on RA is debatable.

Abstract
OBJECTIVE The effect of chimeric anti-tumor necrosis factor alpha (TNF alpha) monoclonal antibody (MAb) therapy on synovial inflammation was studied in order to address the hypothesis that anti-TNF alpha therapy leads to down-regulation of adhesion molecules and a decrease in inflammatory cell influx in synovial tissue (ST). METHODS The immunohistologic features of synovial biopsy specimens, both before and 4 weeks after anti-TNF alpha MAb (cA2) therapy, were studied in 14 patients with rheumatoid arthritis (RA). The patients either received a placebo (n = 2), or were given intravenous doses of cA2 at 10 mg/kg (n = 5) or 20 mg/kg (n = 7). RESULTS A significant (P < 0.03) reduction in the mean scores for T cells and for the adhesion molecules, vascular cell adhesion molecule 1 and E-selectin, was observed after therapy with 10 mg/kg or 20 mg/kg of cA2 in RA patients. CONCLUSION The reduced expression of adhesion molecules, and the decrease in cellularity of rheumatoid ST after cA2 administration support the hypothesis that the antiinflammatory effect of anti-TNF alpha therapy might be partly explained by down-regulation of cytokine-inducible vascular adhesion molecules in ST, with a consequent reduction of cell traffic into joints.

Abstract
Our objective was to investigate the mechanism of accumulation of 99Tcm-labelled non-specific polyclonal human immunoglobulin (99Tcm-HIG) in inflamed synovial tissue (ST) in an experimental animal model of arthritis. Following 99Tcm-HIG scintigraphy, the in vivo localization of 99Tcm-HIG in the ST of knee joints of rats with adjuvant arthritis was studied using immunohistochemical techniques. In addition, the in vitro binding of 99Tcm-HIG to extracellular matrix proteins was analysed by means of immunohistochemistry and enzyme-linked immunosorbent assay (ELISA). After 99Tcm-HIG scintigraphy, 99Tcm-HI was detected in the ST of rats with adjuvant arthritis. 99Tcm-HIG was diffusely distributed and not bound to cells. In vitro incubation of 99Tcm-HIG on the ST of rats with adjuvant arthritis revealed binding of 99Tcm-HIG to inflamed, but not to non-inflamed, ST. In addition, specific binding of 99Tcm-HIG to fibronectin, fibrin, collagen type I and III was demonstrated by ELISA. We conclude that the accumulation of 99Tcm-HIG in inflamed ST can be explained by the binding of 99Tcm-HIG to extracellular matrix proteins.

Abstract
Data concerning the presence of T-cell-derived cytokines in the rheumatic joint are conflicting, challenging the hypothesis that rheumatoid arthritis (RA) is a T-cell-mediated disease. In this study synovial tissue specimens of 11 patients with RA and eight patients with osteoarthritis (OA) were stained for interferon-gamma (IFN-gamma) and its receptor. The level of expression of IFN-gamma was compared with that in tissue specimens of delayed-type hypersensitivity (DTH) reactions of the skin and of chronic tonsillitis. Furthermore, the percentage of T-lymphocytes which stained positive for IFN-gamma was determined using double staining techniques. IFN-gamma and its receptor were detected in all patients with RA and in 7/8 and 3/8, respectively, of patients with OA. Expression of IFN-gamma (P<0.02) and IFN-gamma receptor (P<0.01) in synovial tissue of patients with RA was more abundant compared with that in patients with OA. Although IFN-gamma could be detected in RA synovial tissue, the level of expression was less when compared with DTH reactions of the skin and tonsillitis. The percentage of CD3+ cells being positive for IFN-gamma was approximately 1% in RA, whereas in DTH reactions of the skin it was >90% and in tonsillitis approximately 30%. We conclude that the presence of IFN-gamma and its receptor in RA synovial tissue suggests a role for this cytokine in the ongoing immunological reaction of the inflamed joint.

Abstract
The objective of this paper is to define the expression of adhesion molecules in synovial tissue (ST) from patients with rheumatoid arthritis (RA) with respect to disease duration. Antibodies against adhesion molecules were used for immunohistochemistry to examine ST sections from 11 patients with early RA ( < 1 year), 14 patients with long-standing RA ( > 5 years), and 15 patients with osteoarthritis (OA). Increased cellular infiltration and increased expression of E-selectin, ICAM-1, VCAM-1, PECAM-1, VLA-4, and Mac-1 were found in ST from patients with RA compared to ST from patients with OA. The immunohistological findings were similar for the different stages of RA. The upregulation of adhesion molecules in ST of patients with RA of < 1 year's duration suggests the activation of chronic inflammatory processes in these patients. Therefore, the mechanisms by which therapies directed toward these adhesion molecules exert their effects are likely to be similar for patients with so-called early RA and patients with long-standing RA.

Abstract
OBJECTIVE To study the effect of chimeric anti-CD4 monoclonal antibody (MAb) therapy on synovial inflammation, in order to interpret the clinical experience with anti-CD4 treatment. METHODS The immunohistologic features of synovial biopsy specimens before and 4 weeks after anti-CD4 MAb (cM-T412) therapy were studied in patients with rheumatoid arthritis. The patients received intravenous doses of either placebo (n = 1) or 10 mg (n = 4), 25 mg (n = 2), or 50 mg (n = 1) of cM-T412 daily for 5 consecutive days. RESULTS Although the patients did not experience clinical improvement, significant decreases in the number of circulating CD4+ cells, the degree of synovial inflammatory infiltration, and the mean scores for expression of adhesion molecules were found in the 7 patients 4 weeks after receiving cM-T412. The scores for infiltration with CD4+ and other inflammatory cells were particularly reduced following treatment with either 25 mg or 50 mg cM-T412. Cytokines, such as interleukin-1 beta and tumor necrosis factor alpha, could still be detected in the synovial tissue after treatment. CONCLUSION The decline in the numbers of inflammatory cells and adhesion molecules in synovial tissue after CD4+ cell depletion supports the view that CD4+ T cells orchestrate local cellular infiltration. The lack of clinical effect of anti-CD4 therapy might be explained by an insufficient decrease in the number of synovial CD4+ cells and by the persistence of cytokines. Determination of whether more adequate dosing would lead to a clinical improvement must await further study.

Abstract
OBJECTIVE This study addressed the following questions: How does 99mTc-IgG scintigraphy compare to physical examination in the detection of synovitis as determined histologically, and is 99mTc-IgG scintigraphy a sensitive detector of histologically documented synovitis activity in the absence of clinically detectable knee joint swelling? METHODS The results of measuring synovitis activity by physical examination and by scintigraphy with technetium-99m labelled polyclonal human immunoglobulin G (99mTc-IgG) were compared with the results of histological examination of synovial biopsies taken from the knee joints of patients with rheumatoid arthritis (n = 21), osteoarthritis (n = 9) and various other rheumatic diseases (n = 10). RESULTS The sensitivity of 99mTc-IgG scintigraphy in detecting synovitis activity, as determined histologically (85%), was higher than the sensitivity of joint swelling (65%). In the absence of clinically detectable knee joint swelling the sensitivity of 99mTc-IgG scintigraphy was 83%. CONCLUSION This study shows that 99mTc-IgG scintigraphy is a more sensitive method than physical examination in detecting histologically documented synovitis activity.

Abstract
OBJECTIVE To define the expression and the phenotype of granzyme (Gran) A and B positive cytotoxic cells in synovial tissue (ST) from patients with rheumatoid arthritis (RA) with respect to disease duration and activity. METHODS Using antibodies against GranA and GranB, which serve as markers of activated natural killer (NK) cells and cytotoxic T lymphocytes, ST sections from 10 patients with early RA, 10 patients with longstanding RA, and 10 patients with osteoarthritis were examined. The phenotype of Gran+ cells was determined with double-labeling techniques. RESULTS Gran+ cells, the majority of which were NK cells, were found in ST from patients in all groups. Several of these cells did not express the surface markers CD16, CD56, and CD57. The highest ST expression of GranB was found in patients with early RA. In RA patients, there was a positive correlation of GranB expression with serum levels of acute-phase reactants, but not with histologic scores for inflammation. CONCLUSION Gran+ cells are mainly NK cells, a substantial proportion of which do not express conventional NK cell surface markers. GranB expression is specifically increased in the synovial tissues of patients with RA of short duration.

Abstract
Granzymes A and B are serine proteinases which are stored in the granules of activated cytotoxic T cells and NK cells. Expression of these granzymes by cytotoxic cells in tissues can be used as an activation marker for these cells. To investigate a possible role of cytotoxic lymphocytes in rheumatoid arthritis (RA) and osteoarthritis (OA), we assessed the expression of granzymes A and B by cytotoxic lymphocytes in synovial biopsies from five RA and five OA patients using mAb specific for these serine proteinases. In three of the five RA patients but also in two of the five OA patients granzyme A- and B-expressing lymphocytes were observed in the synovium. Double-labeling immunohistochemical techniques revealed that up to 75% of the granzyme-positive synovial lymphocytes had the CD16+ or CD56+ natural killer cell phenotype. Less than 5% were CD3+, CD8+ cytotoxic T cells, whereas in some patients the phenotype of up to 50% of these cells could not be identified. The presence of granzymes A and B in the synovium of both RA as well as OA patients was confirmed on the molecular level in a second group of 11 RA and 5 OA patients using the polymerase chain reaction. Thus, expression of granzymes A and B occurs in the synovium in patients with RA as well as those with OA. These proteins are mainly expressed by NK cells that may therefore play a role in the pathogenesis of these diseases.

Abstract
It has previously been shown that murine tissue derived T-cells expressing the gamma delta T-cell receptor can respond to autologous (stressed) cells implying the recognition of an autoantigen. Here we report that a large proportion of human synovial tissue and peripheral blood derived V delta 1+ gamma delta T-cell clones proliferate in response to stimulation with autologous and allogeneic EBV-transformed B-lymphoblastoid cell lines (LCL). In contrast, V delta 1- gamma/delta and alpha/beta TCR+ T-cell clones isolated from the same tissue samples did not display proliferation towards the LCL. The proliferative response of these V delta 1+ clones was dependent on contact between responder and stimulator cells and could be blocked by a MoAb to LFA-1 and by antibodies to the gamma delta TCR/CD3 complex. Because the responses of these clones to LCL cells appear to be independent of the gamma-chain co-expressed with the V delta 1-chain these resemble a superantigen response. The capacity of this subset of V delta 1+ T-cell clones to proliferate after stimulation with LCL may imply the recognition of an endogenous epitope. Moreover, since so far we have been able to isolate only LCL reactive gamma delta T-cell clones from synovial tissue and peripheral blood of reactive arthritis patients and not from peripheral blood of healthy individuals, the frequency of such 'autoreactive' gamma delta cells may be higher in these patients.

Abstract
The ability of 99Tcm-labelled polyclonal human immunoglobulin G (99Tcm-IgG) scintigraphy to monitor intra-individual variation in arthritis activity was studied in seven patients with rheumatoid arthritis (RA). These patients were treated with an intra-articular injection of 20 mg triamcinolone hexacetonide. The results of semiquantitative 99Tcm-IgG scintigraphy were compared with the degree of joint swelling and the histological changes observed in synovial biopsies before and 14 days after the injection. In all seven patients the local treatment resulted in a decreased arthritis activity of the treated knee as measured clinically or histologically. This decrease was parallelled, in all patients except one, by a lower uptake of 99Tcm-IgG after the injection when compared to uptake prior to treatment. This study shows that 99Tcm-IgG scintigraphy is able to reflect intra-individual variations in arthritis activity in patients with RA.

A 60-year-old obese woman with type II diabetes mellitus and hepatomegaly exhibited progression of steatosis to hepatitis and cirrhosis. The patient was treated with large amounts of insulin combined with sulfonylurea, resulting in correction of the hyperglycemia. In the subsequent 9 months, weight loss did not occur, whereas insulin therapy could be discontinued. The liver decreased in size, and liver tests normalized. We suggest that intensive treatment of hyperglycemia may result in reversal of insulin resistance in patients with diabetic liver disease, while correction of hyperglycemia can lead to resolution of the hepatic abnormalities associated with diabetes mellitus.

Abstract
In order to relate the clinical expression of Graves' disease and Plummer's disease to age and thyroid hormone level, we prospectively studied 39 patients with Graves' disease and 26 patients with Plummer's disease using a standardized clinical score. Multiple regression analyses were performed with the clinical score as dependent variable and FT4I, age and diagnosis as independent variables. Our results show that patients with Graves' disease tend to have more signs and symptoms than patients with Plummer's disease. In addition, we found a positive correlation between the clinical score and FT4I. We did not find an age dependence of the clinical score, after controlling for diagnosis and FT4I. The age dependence reported by other authors is mainly due to the higher prevalence of Graves' disease among younger age groups in contrast to Plummer's disease.

Abstract
In all types of urinary diversion interchange of electrolytes between blood and the urine in the lumen of the conduit may occur, resulting in electrolyte abnormalities. We describe a 67-year-old woman who developed hyponatremia, hyperkalemia and hypercalcemia following ureteroileocutaneostomy. The hyperkalemia and hypercalcemia were successfully treated with sodium polystyrene sulfonate.

Abstract
We report the cases of two patients who had infections due to Yersinia enterocolitica. The first patient exhibited chronic recurrent fever, hepatic and splenic granulomas, and bone marrow abnormalities, and the second patient presented with enterocolitis with leukocytoclastic vasculitis of the skin. Cultures and agglutination titers were negative. Indirect immunofluorescence techniques with use of serotype-specific antisera and antisera to Yersinia outer-membrane proteins (Yops) were applied to biopsy specimens, and immunoblotting techniques for determining class-specific circulating antibodies to Yops were used for demonstrating these unusual manifestations of Y. enterocolitica infections.

Abstract
A 66-year-old man with chronic idiopathic intestinal pseudoobstruction was admitted for pneumatosis cystoides intestinalis, complicated by pneumoperitoneum. The latter conditions resolved after treatment with metronidazole. There was no favorable effect of the prokinetic agents cisapride and erythromycin. To the authors' knowledge, this is the first reported case of successful treatment of pneumatosis cystoides intestinalis with metronidazole in primary chronic intestinal pseudoobstruction.
