Cím:Regulatory T cells in peripheral blood of patients with mixed connective tissue disease / Baráth Sándor, Sipka Sándor, Szodoray Péter, Szegedi Andrea, Aleksza Magdolna, Végh Judit, Szegedi Gyula, Bodolay Edit
Dátum:2006
Megjegyzések:To determine the percentage and absolute number of CD4+ regulatory T-cells (Treg) in 48 patients with mixed connective tissue disease (MCTD). METHODS: Data were classified on the basis of the stage of the disease: 17 patients were in the active stage and 31 in the inactive stage. The absolute number of CD4+/intracellular interleukin-10+ (IL-10+) and CD4+CD25+high Treg cells was determined by flow cytometry. The percentage of CD4+CD25+high suppressor T-cells was determined on the basis of Foxp3 expression. RESULTS: The percentage and the absolute number of CD4+CD25+high Treg cells were lower in patients than in healthy controls (p<0.04), and were further decreased in patients with active MCTD and were lower than in the inactive stage (p<0.01). There was an increase in the percentage and absolute number of CD4+IL-10+ Treg cells in patients with MCTD compared to the healthy controls (p<0.02). The percentage of CD4+IL-10+ Treg cells was higher in the active stage of MCTD than in the inactive stage of the disease (p<0.005). However, we did not find any significant difference in the absolute number of CD4+IL-10+ Treg cells between the patients in the active and inactive stages of MCTD. CONCLUSION: Our results suggest that the decrease in the number of CD4+CD25+high Treg cells in an important factor in the immunoregulatory disturbance in patients with MCTD. We suggest that the increase in the number of CD4+IL-10+ Treg cells is a compensatory mechanism aiming to restore the balance between type 1 and type 2 cytokines in MCTD.

Megjegyzések:Studies indicate that ankylosing spondylitis (AS), as well as rheumatoid arthritis, may be associated with accelerated atherosclerosis and vascular disease. We assessed endothelial dysfunction, carotid atherosclerosis, and aortic stiffness in AS in context with clinical and laboratory measurements. METHODS: Forty-three patients with AS and 40 matched healthy controls were studied. We assessed common carotid intima-media thickness (ccIMT), flow-mediated vasodilation (FMD), and pulse-wave velocity (PWV) in association with age, disease duration, smoking habits, body mass index, patient's assessment of pain and disease activity, Bath AS Disease Activity Index, Bath AS Functional Index (BASFI), metric measurements, erythrocyte sedimentation rate, C-reactive protein, and HLA-B27 status. RESULTS: We found impaired FMD (6.85 +/- 2.98% vs 8.30 +/- 3.96%; p = 0.005), increased ccIMT (0.65 +/- 0.15 vs 0.54 +/- 0.15 mm; p = 0.01), and higher PWV (8.64 +/- 2.44 vs 8.00 +/- 1.46 m/s; p = 0.03) in patients with AS compared to controls, respectively. We also found that ccIMT negatively correlated with FMD (r = -0.563; p = 0.0001) and positively correlated with PWV (r = 0.374; p = 0.018). Both ccIMT and PWV correlated with disease duration (r = 0.559; p = 0.013 and r = 0.520; p = 0.022, respectively), BASFI (r = 0.691; p = 0.003 and r = 0.654; p = 0.006), decreased lumbar spine mobility (r = -0.656; p = 0.006 and r = -0.604; p = 0.013), chest expansion (r = -0.502; p = 0.047 and r = -0.613; p = 0.012), and increased wall-occiput distance (r = 0.509; p = 0.044 and r = 0.614; p = 0.011). CONCLUSION: In this well characterized AS population, impaired FMD and increased ccIMT and PWV indicate abnormal endothelial function and increased atherosclerosis and aortic stiffness, respectively. The value of noninvasive diagnostic tools needs to be further characterized.

Cím:Anti-endothelial cell antibodies in mixed connective tissue disease : frequency and association with clinical symptoms / E. Bodolay, I. Csipő, I. Gál, S. Sipka, E. Gyimesi, Z. Szekanecz, G. Szegedi
Dátum:2004
Megjegyzések:AbstractOBJECTIVE: Anti-endothelial cell antibodies (AECA) have been described in a number of systemic autoimmune-inflammatory diseases. However, little is known about the relationship of AECA with mixed connective tissue disease (MCTD).METHODS: Using an ELISA, the presence of AECA was evaluated in the sera of 33 patients with MCTD and of 30 healthy subjects as controls. Serum levels of AECA were correlated with clinical activity, as well as the existence of various organ manifestations.RESULTS: Significantly increased AECA production was observed in MCTD patients (OD = 0.337+/-0.193) compared to controls (OD = 0.136+/-0.065). In addition, patients with active MCTD exerted significantly elevated serum AECA levels (OD = 0.487+/-0.090) than did patients with inactive MCTD (OD = 0.135+/-0.040) or controls. MCTD patients with pulmonary hypertension had a tendency of increased serum AECA levels (OD = 0.452+/-0.080) compared to patients without this manifestation (OD = 0.307+/-0.039). Sera of MCTD patients with AECA concentrations higher or lower than the mean serum AECA level in controls+2SD (OD = 0.266) were considered as AECAhigh (n = 19/33) and AECAlow (n = 14/33), respectively. Interestingly, all patients with active disease had AECAhigh, while all inactive MCTD patients had AECAlow sera. IgG purified from ten MCTD sera (OD = 0.415+/-0.290) showed a tendency to up-regulate E-selectin expression on cultured human umbilical vein endothelial cells (HUVEC) compared to IgG from control sera. In addition, AECAhigh MCTD sera exerted significantly increased stimulatory effect on endothelial E-selectin expression (OD = 0.651+/-0.190) compared to AECAlow (OD = 0.178+/-0.110) or control sera (OD = 0. 131+/-0.080).CONCLUSION: AECA may activate endothelial cells by the up-regulation of E-selectin expression and thus may be implicated in the pathogenesis of MCTD. Furthermore, serum AECA may be a useful marker of endothelial activation and clinical activity in this disease.

Cím:The in vitro treatment with vitamin D3 is ineffective on the expression of PKC isoenzymes, but decreases further the impaired production of IL-2 in the T lymphocytes of SLE patients / Gabriella Czifra, Balázs Tóth, Ildikó Kovács, Tamás Bíró, Zoltán Griger, Sándor Baráth, Tünde Tarr, Margit Zeher, Sándor Sipka
Dátum:2014
Megjegyzések:The objective of the study was to investigate the possibility whether the in vitro treatment with vitamin D3 can restore the impaired expression of protein kinase C (PKC) isoenzymes and IL-2 production in the lymphocytes of patients with systemic lupus erythematosus (SLE). Purified T lymphocytes from 14 patients with SLE and 13 healthy controls were cultured for 48 h in the presence and absence of 1 and 100 nM doses of vitamin D3. The expressions of various PKC isoenzymes were tested by Western blot analysis, and the amounts of various cytokines were detected by ELISA in the culture supernatants. Neither the low (1 nM) nor the high (100 nM) doses of vitamin D3 (1α,-25-dihydroxyvitamin) applied in vitro for 48 h were able to restore the decreased expression of PKC isoenzymes in the T cells of SLE patients. However, 100 nM of vitamin D3 significantly increased the release of IL-10, but suppressed the production of IL-2, IL-6, interferon γ and TNF α in the culture supernatants of both groups. As the low production of IL-2 is one of the main pathologic features of SLE, we recommend to avoid the use of high doses of vitamin D3 for treatment of lupus patients with vitamin D3 deficiency.

Cím:Endothelial dysfunction and atherosclerosis in rheumatoid arthritis : a multiparametric analysis using imaging techniques and laboratory markers of inflammation and autoimmunity / Kerekes György, Szekanecz Zoltán, Dér Henrietta, Sándor Zsuzsa, Lakos Gabriella, Muszbek László, Csípő István, Sipka Sándor, Seres Ildikó, Paragh György, Kappelmayer János, Szomják Edit, Veres Katalin, Szegedi Gyula, Shoenfeld Yehuda, Soltész Pál
Dátum:2008
Megjegyzések:Cardiovascular disease is a leading cause of mortality in rheumatoid arthritis (RA). Endothelial dysfunction often precedes manifest atherosclerosis. We assessed endothelial dysfunction and atherosclerosis in RA in context with laboratory markers. METHODS: Fifty-two patients with RA and 40 matched healthy controls were studied. We assessed common carotid intima-media thickness (ccIMT) and flow- (FMD) and nitroglycerine-mediated vasodilation (NMD). We also assayed numerous immunological and metabolic laboratory markers. RESULTS: FMD was significantly lower in RA (5.32% +/- 4.66%) compared to controls (8.30% +/- 3.96%) (p = 0.001). NMD was preserved in RA. ccIMT was significantly greater in patients with RA (0.63 +/- 0.14 mm) versus controls (0.54 +/- 0.15 mm) (p = 0.012). In patients with RA, ccIMT correlated with FMD% (R = -0.318, p = 0.022), age (R = 0.831, p < 0.001), and anti-dsDNA levels (R = 0.463, p = 0.006). FMD% correlated with serum interferon-gamma (IFN-gamma) levels (R = 0.516, p = 0.014). NMD% correlated inversely with the percentage of Th0 lymphocytes (R = -0.636, p = 0.006), serum immune complex (R = -0.692, p < 0.001), and IgM levels (R = -0.606, p = 0.003). Patients with RA were divided as "low" (< 0.65 mm) versus "high" (> 0.65 mm) ccIMT groups, and into "normal" (> 5%) versus "impaired" (< 5%) FMD% subsets. Low and high ccIMT groups differed significantly in age and serum interleukin 1 (IL-1) and anti-dsDNA levels. RA patients with normal versus impaired FMD% differed significantly in age, disease duration, and serum IFN-gamma levels. Lipoprotein(a) [Lp(a)] also correlated with rheumatoid factor (RF) and C-reactive protein (CRP); homocysteine (HCy) correlated with CRP and correlated inversely with folate and vitamin B12 production. Paraoxonase-1 (PON-1) activity correlated with serum tumor necrosis factor-alpha(TNF-alpha) and IL-6 levels. CONCLUSION: This was a well characterized RA population, where FMD and ccIMT were impaired, indicating early endothelial dysfunction and accelerated atherosclerosis, respectively. RA-related autoimmune-inflammatory mechanisms and metabolic factors including anti-CCP, RF, CRP, circulating immune complexes, IgM, TNF-alpha, IL-6, Th0/Th1 ratio, HCy, folate, vitamin B12, and PON-1 may all be involved in the development of vascular disease in RA. Although ccIMT and FMD, as well as some laboratory factors, have been assessed by other investigators in RA-associated atherosclerosis, our results regarding the possible involvement of anti-CCP, anti-dsDNA, Lp(a), some cytokines, and PON-1 activity are novel. Early determination of FMD% and ccIMT may be useful to assess RA patients with high cardiovascular risk.

Cím:Antiprothrombin and antiannexin V antibodies imply risk of thrombosis in patients with systemic autoimmune diseases / Gabriella Lakos, Emese Kiss, Nora Regeczy, Peter Tarjan, Pal Soltesz, Margit Zeher, Edit Bodolay, Gabriella Szucs, Szilvia Szakony, Sandor Sipka, Gyula Szegedi
Dátum:2000
Megjegyzések:To investigate the relationship between antiprothrombin (aPT) and antiannexin V (aANX) autoantibodies of IgG isotype and thrombosis in patients with systemic autoimmune diseases. To compare the clinical relevance of these antibodies to that of anticardiolipin (aCL), anti-beta2-glycoprotein I antibodies (anti-beta2-GPI), and lupus anticoagulant (LAC). METHODS: Serum IgG aPT, aANX, aCL, and anti-beta2-GPI levels were measured by solid phase enzyme immunoassay in the sera of 70 patients with systemic autoimmune diseases, 35 with antiphospholipid syndrome (APS) and 35 without APS. Medical records were analyzed, and associations of the antibodies with clinical features of APS were assessed. RESULTS: Patients with APS had higher frequency of aPT (p = 0.001) and aANX (p = 0.002) compared to patients without APS. Thrombotic events occurred more frequently in those with aPT or aANX than those without (p = 0.005, p = 0.006, respectively). The presence of aPT and aANX was found to be highly specific for APS. CONCLUSION: Measurement of aPT and aANX antibodies may be of value in confirming the diagnosis of APS, and in evaluating risk of venous and arterial thrombosis in patients with systemic autoimmune diseases.

Cím:Altered T-cell and regulatory cell repertoire in patients with diffuse cutaneous systemic sclerosis / Papp Gábor, Horvath Ildikó Fanny, Barath Sándor, Gyimesi Edit, Sipka Sándor, Szodoray Péter, Zeher Margit
Dátum:2011
Megjegyzések:The aim of this study was to evaluate a wide spectrum of peripheral immune-competent cell types, reflecting overall disturbances in immune homeostasis, characteristic of systemic sclerosis (SSc). We also assessed visceral organ involvement and evaluated the relationship between cell proportions and clinical symptoms of the disease. Methods: Twenty-one patients with diffuse cutaneous SSc (dcSSc) and 15 healthy individuals participated in the study. Peripheral blood lymphocyte subgroups were quantified by flow cytometry, soluble cytokines were assessed by enzyme-linked immunosorbent assay (ELISA), serum complement levels were measured by nephelometry, and autoantibodies were determined by indirect immunofluorescence staining and ELISA technique. Functional tests of regulatory T (Treg) cells were also carried out. Results: Patients with SSc had higher percentages of activated CD3+/HLA-DR+ T cells. Comparing naive vs. memory subsets of CD4+ and CD8+ T cells, a shift towards central memory phenotype was observed in SSc. Natural killer (NK) and T-helper (Th)17 cell percentages were increased, while NKT, Th1, Treg type 1 (Tr1), and CD4+CD25+ Treg cell percentages were decreased in patients. Moreover, the suppressor activity of CD4+CD25+ Treg cells was lower in SSc. Negative correlations occurred between modified Rodnan skin score (MRSS) and Tr1 cell percentages and between complement levels and CD4+CD25+ Treg cells. We also found decreased interleukin (IL)-10 levels in SSc. Conclusions: Our data suggest that the increased Th17/CD4+CD25+ Treg ratio and the altered regulatory function of CD4+CD25+ Treg cells play an important role in the development of SSc. Moreover, our study reveals the potential role of the decreased profile of IL-10-producing Tr1 cells in the progression of disproportionate immune responses in SSc.

Cím:Vitamin D receptor gene polymorphism in rheumatoid arthritis and associated osteoporosis / Rass, P., Pakozdi, A., Lakatos, P., Zilahi, E., Sipka, S., Szegedi, G., Szekanecz, Z.
Dátum:2006
ISSN:0172-8172
Megjegyzések:Rheumatoid arthritis (RA) is commonly associated with decreased bone mineral density (BMD) due to numerous factors. BsmI polymorphism of the vitamin D receptor (VDR) gene has been implicated in the pathogenesis of osteoporosis. Vitamin D has several immunomodulatory effects and thus may play a role in the course of arthritis. However, little data is available on the possible relationship between RA and VDR gene polymorphisms. In this study, the frequency of BsmI polymorphism genotypes were compared with that found in other countries. In this study, 64 RA patients and 40 healthy controls were tested for VDR gene BsmI polymorphism genotypes. Frequencies of B and b alleles were associated with markers of bone metabolism and RA. Among control subjects, the frequency of the BB genotype is relatively high (27.5%). In RA with secondary osteopenia/osteoporosis the BB genotype was more rare, the bb was more common than in control subjects. Markers of bone metabolism were associated with the B allele. RA patients carrying the B allele had lower BMD and increased bone loss over 1 year. The B allele was also correlated with increased osteoclast and osteoblast function, as determined by the assessment of biochemical markers of bone metabolism. Rheumatoid factor titer, which is an independent marker for disease progression in RA, was higher in bb patients. Our data suggest, that the imbalance in B and b allele expression may be involved in the pathogenesis of RA-associated osteoporosis. The possible involvement of vitamin D and VDR gene polymorphisms in the development and progression of RA needs further elucidation.

Megjegyzések:OBJECTIVE: To investigate the release of arachidonic acid (AA) in unfractionated peripheral blood mononuclear cells (PBMC), separated monocytes and T lymphocytes of patients with systemic lupus erythematosus (SLE). METHODS: AA release was measured in cells from 56 patients with SLE and from 48 controls. Of the 56 patients with SLE, 38 were receiving glucocorticosteroids and 18 were not. [3H]AA was incorporated into the membranes of PBMC and purified subsets of monocytes and T lymphocytes. The release of [3H]AA was measured both in nonstimulated cells cultured for 24 h and in cell cultures stimulated by phorbol ester (PMA) and Ca2+ ionophore for 4 h. RESULTS: In the PBMC of SLE patients not taking glucocorticosteroids, the release of AA was decreased in both stimulated and nonstimulated cells. There was a decrease of AA production in monocytes but not in T lymphocytes. This phenomenon could be observed in the active and inactive phases of the disease. CONCLUSION: A defect in AA production may exist in the peripheral monocytes of patients with SLE, resulting in decreased release of AA in patients not receiving glucocorticosteroid therapy.
