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:	Increased arterial stiffness as the marker of vascular involvement in systemic sclerosis / Tímár O., Soltész P., Szamosi S., Dér H., Szántó S., Szekanecz Z., Szücs G.
Dátum:	2008
Megjegyzések:	OBJECTIVE: Endothelial dysfunction and vasculopathy of the small and large vessels are crucial pathogenic factors in systemic sclerosis (SSc). Accelerated atherosclerosis and impaired flow-mediated vasodilation have been described in SSc. We evaluated arterial stiffness in patients with SSc compared to healthy controls. METHODS: Augmentation index (AI) and pulse wave velocity (PWV) of the brachial artery were measured in 40 patients with SSc and 35 age and sex matched healthy controls using an arteriograph system. RESULTS: AI was significantly higher in SSc patients (9.02) compared to controls (-41.15) (p < 0.0001). PWV was similarly higher in patients with SSc (9.67 m/s) than in controls (8.00 m/s) (p = 0.0017). PWV was significantly higher in patients with localized SSc (10.04 +/- 2.01 m/s) compared to those with diffuse SSc (8.39 +/- 1.87 m/s) (p = 0.034). There was a significant, positive linear correlation between AI and PWV (r = 0.32, p = 0.045). We also observed significant correlations between AI and age (r = 0.31, p = 0.048), PWV and age (r = 0.36, p = 0.021), and PWV and disease duration (r = 0.40, p = 0.011) in SSc patients. CONCLUSION: Increased AI and PWV of the aorta in comparison to age and sex matched healthy controls indicate increased large-vessel stiffness in patients with SSc. PWV and AI are reproducible indicators of the presence and degree of arterial stiffening. Because arterial stiffness may correlate with disease duration and age in patients with SSc, it may be a useful diagnostic test in the assessment of arterial function. Increased vascular stiffness may be therapeutically targeted by statins and other vasoprotective agents during the management of SSc.
