Cím:Impaired endothelial function and increased carotid intima-media thickness in association with elevated von Willebrand antigen level in primary antiphospholipid syndrome / Der H., Kerekes G., Veres K., Szodoray P., Toth J., Lakos G., Szegedi G., Soltesz P.
Dátum:2007
Megjegyzések:Primary antiphospholipid syndrome (APS) is characterized by venous or arterial thrombotic events and/or recurrent abortions, fetal death, preeclasmpsia, eclampsia in the presence of anticardiolipin antibodies or lupus anticoagulant, in the absence of accompanying diseases. Antiphospholipid antibodies can activate endothelial cells, and were recently implicated in atherosclerosis. To assess potential endothelial impairment and early signs of atherosclerosis, flow-mediated (endotheliumdependent) and nitrate-mediated (endothelium independent) vasodilation, as well as von Willebrand factor antigen level and carotid artery intima-media thickness (IMT) were measured in patients with primary antiphospholipid syndrome and in healthy controls. Flow-mediated vasodilation in patients with primary APS was significantly lower than that of controls (3.43 +/- 2.86% versus 7.96 +/- 3.57%; P < 0.0001). We also found significantly higher von Willebrand antigen levels in patients with primary APS than in the control group (157.91 +/- 52.45% versus 125.87 +/- 32.8%; P = 0.012). Moreover, carotid artery IMT was significantly larger in the primary APS group compared to controls (0.714 +/- 0.2 mm versus 0.58 +/- 0.085 mm; P = 0.0037). Our results reflect ongoing endothelial damage and accelerated atherosclerosis in patients with primary APS, and suggest that vasoprotective therapy may be beneficial in the treatment of these patients.

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

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.
