Megjegyzések:The role of platelets in the development of atherosclerosis and obesity-related prothrombotic state is still under investigation. In this cross-sectional cohort study, we measured the levels of different platelet activation markers and evaluated their relationship with carotid intima-media thickness (IMT) along with other atherosclerotic risk factors in obese patients with or without atherosclerotic co-morbidities. We enrolled 154 obese patients, including 98 with either hypertension, type 2 diabetes mellitus or dyslipidaemia, 56 without these co-morbidities and 62 age- and sex-matched healthy controls. Platelet P-selectin expression and the number of platelet-derived microparticles (PMPs) were measured by flow cytometry; soluble P-selectin levels were analysed by ELISA and Thr715Pro P-selectin polymorphism was determined by PCR-RFLP. Carotid IMT was examined by ultrasonography. The levels of platelet activation parameters were significantly elevated in all obese subjects with increased carotid IMT compared to healthy controls. There was no effect of Thr715Pro genotype on soluble P-selectin levels in obese individuals contrary to normal subjects. Significant and positive association was revealed between carotid IMT and platelet P-selectin (p<0.0001), soluble P-selectin (p=0.039) and PMP (p=0.0001) levels. After adjusting for multiple variables, independent association was found between soluble P-selectin and fibrinogen (p=0.007), PMP levels and body mass index (p<0.0001) as well as platelet P-selectin and carotid IMT (p=0.012) plus plasminogen activator inhibitor-1 (p=0.009). In conclusion, P-selectin and PMP levels showed positive associations with abnormal carotid IMT and other risk factors in obesity suggesting a critical role of enhanced platelet reactivity in atherosclerotic wall alteration.

Cím:Major changes of von Willebrand factor multimer distribution in cirrhotic patients with stable disease or acute decompensation / Eszter Palyu, Jolan Harsfalvi, Tamas Tornai, Maria Papp, Miklos Udvardy, Katalin Szekeres-Csiki, Lajos Pataki, Karen Vanhoorelbeke, Hendrik B.

Megjegyzések:Background and aims: There is an unstable balance between pro- and anti-haemostatic processes in patients with cirrhosis. We hypothesized, that in patients with acute decompensation (AD) the major alterations of von Willebrand factor (VWF) could contribute to the prothrombotic situation as compared to patients with stable (ST) cirrhosis. Methods: We analyzed different parameters of VWF, including detailed multimer distribution by densitometry and platelet adhesion together with ADAMTS13 activity and antigen and C-reactive protein (CRP) levels in patients with ST (n=99), with AD (n=54) and controls (n=92). Results: VWF antigen, ristocetin cofactor as well as collagen binding activities were elevated in both cirrhotic groups in a stepwise manner. There was a decrease in high and an increase in low molecular weight multimer ratios in the majority of ST cirrhosis. However, in 24 out of 54 AD patients ultra-large VWF multimers (ULMWM) were found. ADAMTS13 activity in ST and AD patients without ULMWM was similar to controls [median, (IQR)%: 98 (67-132) and 91 (60-110) vs. 106 (88-117), respectively]. The presence of ULMWM in AD patients was associated with low ADAMTS13 activity [33 (24-49)%] and high CRP level [23 (7.1-83.6)mg/l]. Adhesion of normal platelets showed a stepwise increase in the presence of cirrhotic plasmas, reaching the highest level in AD patients with ULMWM. Conclusion: Characteristic changes of VWF parameters are seen in ST cirrhosis. In AD patients highly increased VWF and reduced ADAMTS13 activity could be found, along with the presence of ULMWM, which are possible markers and contributors of the disease progression.
