Megjegyzések:To determine the prevalence of and independent factors associated with joint involvement in a large population of patients with systemic sclerosis (SSc). METHODS: This study was cross-sectional, based on data collected on patients included in the European League Against Rheumatism (EULAR) Scleroderma Trials and Research (EUSTAR) registry. We queried this database to extract data regarding global evaluation of patients with SSc and the presence of any clinical articular involvement: synovitis (tender and swollen joints), tendon friction rubs (rubbing sensation detected as the tendon was moved), and joint contracture (stiffness of the joints that decreased their range of motion). Overall joint involvement was defined by the occurrence of synovitis and/or joint contracture and/or tendon friction rubs. RESULTS: We recruited 7286 patients with SSc; their mean age was 56 +/- 14 years, disease duration 10 +/- 9 years, and 4210 (58%) had a limited cutaneous disease subset. Frequencies of synovitis, tendon friction rubs, and joint contractures were 16%, 11%, and 31%, respectively. Synovitis, tendon friction rubs, and joint contracture were more prevalent in patients with the diffuse cutaneous subset and were associated together and with severe vascular, muscular, renal, and interstitial lung involvement. Moreover, synovitis had the highest strength of association with elevated acute-phase reactants taken as the dependent variable. CONCLUSION: Our results highlight the striking level of articular involvement in SSc, as evaluated by systematic examination in a large cohort of patients with SSc. Our data also show that synovitis, joint contracture, and tendon friction rubs are associated with a more severe disease and with systemic inflammation.

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:Serum cytokine levels and type 1 and type 2 intracellular T cell cytokine profiles in mixed connective tissue disease / Bodolay, E., Aleksza, M., Antal-Szalmás, P., Végh, J., Szodoray, P., Soltész, P., Szegedi, A., Szekanecz, Z.
Dátum:2002
Megjegyzések:To determine serum cytokine concentrations and intracellular cytokine production of CD4+ and CD8+ T cells in 20 patients with mixed connective tissue disease (MCTD). METHODS: Detailed analysis of cytokine production; 8 patients were in the active stage, 12 in the inactive stage of the disease. Serum concentrations of interferon-gamma (IFN-gamma), interleukin 4 (IL-4), and IL-10 were assessed by ELISA. Intracellular content of IFN-gamma, IL-4, and IL-10 in CD4+ and CD8+ peripheral blood T cell and lymphocyte subsets was determined by flow cytometry. RESULTS: Serum concentrations of both type 1 and type 2 cytokines were significantly higher in patients with MCTD than in healthy controls. IFN-gamma expression of CD4+ and CD8+ T cells did not differ comparing all patients to controls. In patients with active MCTD, the percentage of CD8+/IFN-gamma+ Tc1 cells was significantly increased compared to inactive disease or to controls (p < 0.05). IL-4 expression of CD4+ T cells was scarcely detectable in MCTD, while a subpopulation of CD8+ Tc2 cells produced IL-4. A higher percentage of these CD8+/IL-4+ Tc2 cells were detected in patients with MCTD, especially in active disease, compared to controls (p < 0.05). The percentage of IL-10-expressing CD4+ and CD8+ T cells was higher in patients than in controls (p < 0.05). Again, CD4+ and CD8+ T cells from patients with active MCTD produced significantly more IL-10 than cells in patients with inactive disease or in controls (p < 0.05). CONCLUSION: Our results suggest that MCTD is associated with increased production of both type 1 (IFN-gamma) and type 2 cytokines (IL-4, IL-10). Cytokine production is usually higher in active MCTD than in inactive disease. CD8+ T cells may produce more IFN-gamma and IL-10 in comparison to CD4+ T cells. Patients with active disease have more IL-4-expressing Tc2 cells and IL-10-expressing Th2 and Tc2 cells than patients with inactive MCTD or controls. In MCTD, increased IL-10 production by Th2 and Tc2 cells may be an attempt by the immune system to downregulate the inflammatory reaction, although this effect may not be sufficient to restore the physiological Th1/Th2 balance in MCTD.

Megjegyzések:To study the survival rate and prognostic indicators of mixed connective tissue disease (MCTD) in a Hungarian population. METHODS: Two hundred eighty patients with MCTD diagnosed between 1979 and 2011 were followed prospectively. Clinical features, autoantibodies, and mortality data were assessed. Prognostic factors for survival were investigated and survival was calculated from the time of the diagnosis by Kaplan-Meier method. RESULTS: A total of 22 of 280 patients died: the causes of death were pulmonary arterial hypertension (PAH) in 9 patients, thrombotic thrombocytopenic purpura in 3, infections in 3, and cardiovascular events in 7. The 5, 10, and 15-year survival rates after the diagnosis was established were 98%, 96%, and 88%, respectively. The deceased patients were younger at the diagnosis of MCTD compared to patients who survived (35.5 ± 10.4 vs 41.8 ± 10.7 yrs; p < 0.03), while there was no difference in the duration of the disease (p = 0.835). Our cohort study showed that the presence of cardiovascular events (p < 0.0001), esophageal hypomotility (p = 0.04), serositis (p < 0.001), secondary antiphospholipid syndrome (p = 0.039), and malignancy (p < 0.001) was significantly higher in the deceased patients with MCTD. The presence of anticardiolipin (p = 0.019), anti-β2-glycoprotein I (p = 0.002), and antiendothelial cell antibodies (p = 0.002) increased the risk of mortality. CONCLUSION: Overall, PAH remained the leading cause of death in patients with MCTD. The prevalence of cardiovascular morbidity and mortality, malignancy, and thrombotic events increased during the disease course of MCTD. The presence of antiphospholipid antibodies raised the risk of mortality.

Cím:Relationship between rheumatoid factor isotypes and IgG anti-cyclic citrullinated peptide antibodies / Jaskowski, T. D., Hill, H. R., Russo, K. L., Lakos, G., Szekanecz, Z., Teodorescu, M.

Megjegyzések:To validate in a general patient population (GPP) the clinical value of measuring rheumatoid factor (RF) isotypes in relationship to IgG anti-cyclic citrullinated peptide (CCP) antibodies (CCP2 and CCP3). METHODS: Serum samples were obtained as follows: 1021 GPP, for whom RF was ordered for diagnosis, 137 with rheumatoid arthritis (RA), 100 healthy blood donors (HBD), and 50 with systemic lupus erythematosus. Turbidimetry and ELISA were utilized for RF screening, and individual RF isotypes and IgG anti-CCP antibodies were measured by ELISA; RF IgG was measured after pepsin digestion. RESULTS: We validated the generally accepted 90%-98% positive predictive value (PPV) and about 68% sensitivity of the anti-CCP2 test on our diagnosed cohorts as 96% (95% CI 89-99) and 65% (95% CI 56-73), respectively. The 282 RF IgM+ specimens identified in the GPP were subdivided into 3 subsets: (1) 83 as RF IgM+ IgG+ IgA+ with 63% (95% CI 51-73) anti-CCP2+ (i.e., sensitivity similar to the RA cohort); (2) 50 as RF IgM+ IgG- IgA+ with significantly fewer anti-CCP2+ (22%; 95% CI 12-36); and (3) about half as IgM+ IgG- IgA- with just 3% (95% CI 1-8) anti-CCP2+, i.e., not significantly different from the 1% (95% CI 0-5) in HBD. Thus, the chance for a specimen in the GPP to be anti-CCP2+ (i.e., to come from an RA patient) was increased by 7- and 21-fold, respectively, by identifying RF IgA and IgG in addition to IgM. About one-third of anti-CCP- RA patients in our cohort were RF IgM+ IgG+ IgA+, reflected as 3.4% in the anti-CCP2- GPP. The agreement between anti-CCP2 and anti-CCP3 was significantly higher for RF+ RA and GPP patients, 86% (95% CI 78-93) and 83% (95% CI 73-91), respectively, than for the RF- RA (27%; 95% CI 6-61), RF- GPP (4%; 95% CI 0-19), and non-RA controls. Anti-CCP2 but not anti-CCP3 significantly distinguished the HBD from the GPP (95% CI). CONCLUSION: Measurement of the 3 isotypes of RF may increase by 7- to 21-fold the chance of making the serologic diagnosis of RA; a testing algorithm is proposed. The anti-CCP antibody response appears significantly less peptide-specific in the presence of IgM RF than in its absence.

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.

Megjegyzések:Objective. Tocilizumab, a humanized anti-interleukin-6 receptor monoclonal antibody, has recentlybeen approved as a biological therapy for rheumatoid arthritis (RA) and other diseases. It is not knownif there are characteristic changes in gene expression and immunoglobulin G glycosylation during therapyor in response to treatment.Methods. Global gene expression profiles from peripheral blood mononuclear cells of 13 patients withRA and active disease at Week 0 (baseline) and Week 4 following treatment were obtained together withclinical measures, serum cytokine levels using ELISA, and the degree of galactosylation of the IgG Nglycanchains. Gene sets separating responders and nonresponders were tested using canonical variatesanalysis. This approach also revealed important gene groups and pathways that differentiate respondersfrom nonresponders.Results. Fifty-nine genes showed significant differences between baseline and Week 4 and thus correlatedwith treatment. Significantly, 4 genes determined responders after correction for multiple testing. Tenof the 12 genes with the most significant changes were validated using real-time quantitative polymerasechain reaction. An increase in the terminal galactose content of N-linked glycans of IgG was observed inresponders versus nonresponders, as well as in treated samples versus samples obtained at baseline.Conclusion. As a preliminary report, gene expression changes as a result of tocilizumab therapy in RAwere examined, and gene sets discriminating between responders and nonresponders were found andvalidated. A significant increase in the degree of galactosylation of IgG N-glycans in patients with RAtreated with tocilizumab was documented.

Cím:Association of ARTS1 gene polymorphisms with ankylosing spondylitis in the Hungarian population : the rs27044 variant is associated with HLA-B*2705 subtype in Hungarian patients with ankylosing spondylitis / Borbála Pazár, Enikő Sáfrány, P. Gergely, Sándor Szántó, Zoltán Szekanecz, Gyula Poór

Megjegyzések:OBJECTIVE: Associations have been found between ankylosing spondylitis (AS) and polymorphisms in the aminopeptidase regulator of TNFR1 shedding (ARTS1) gene. We studied the association of 5 polymorphisms within the ARTS1 gene with AS in Hungarian patients. We also investigated the prevalence of HLA-B27 subtypes in the Hungarian population. METHODS: A case-control study including 297 patients with AS and 200 sex and ethnically matched healthy controls was performed. Patients and controls were genotyped for rs27044, rs17482078, rs10050860, rs30187, and rs2287987 single-nucleotide polymorphisms using real-time polymerase chain reaction (PCR) allelic discrimination. HLA-B27 subtypes were determined with PCR sequence-specific primer (PCR-SSP) technique. RESULTS: We observed a significant increase in the minor allele frequency of rs27044 (p = 0.001) in the AS group compared to controls. The minor allele frequencies of rs10050860 (p = 0.006) and rs2287987 (p = 0.002) showed a significant decrease in AS patients compared to controls. Haplotype analysis revealed association of 2 ARTS1 haplotypes with AS in the Hungarian population. We found that HLA-B*2705 was the predominant subtype in Hungarians with AS. Carriage of the G allele of rs27044 was significantly associated with the HLA-B*2705 subtype (p = 0.009) in AS patients. CONCLUSION: We confirmed reported associations of ARTS1 gene polymorphisms with AS in a Hungarian cohort study. We found HLA-B*2705 as the predominant subtype in Hungarian AS patients in accord with other studies on Caucasian populations. Our results suggest that the ARTS1 gene variants together with HLA-B27 strongly contribute to disease susceptibility in patients with AS.
