Mean platelet volume and its relationship with carotid atherosclerosis in subjects with non-alcoholic fatty liver disease

چکیده
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is linked to an increased risk of cardiovascular disease. Mean platelet volume (MPV), a determinant of platelet activation, is an emerging risk factor for atherothrombosis. AIMS The aim of this study was to investigate the levels of MPV in subjects with NAFLD having no confounding factors for atherosclerosis such as obesity, diabetes mellitus, and hypertension. In addition, the possible relationship between MPV and carotid artery intima media thickness (CIMT), a well known marker of subclinical atherosclerosis, was also studied. METHODS MPV and CIMT levels were measured in 60 biopsy-proven NAFLD subjects and 54 healthy controls. Age and sex were similar between two groups. RESULTS Body mass index and waist circumference levels were higher in the NAFLD group when compared to the controls. There were no differences between the two groups regarding LDL cholesterol levels, whereas HDL cholesterol levels were lower in the NAFLD group. MPV and CIMT levels were not different between the two groups. According to the correlation analyses, CIMT levels were positively correlated to age in patients with NAFLD. However, no significant correlation was found between MPV and CIMT levels. CONCLUSIONS The results of this study do not show any difference in MPV levels between subjects with NAFLD and controls. These finding suggests that in the absence of other metabolic risk factors, MPV might not be involved in the mechanism(s) of increased cardiovascular risk in NAFLD.

Background and Aim: A lot of studies is done about various components of the metabolic syndrome in association with non-alcoholic fatty liver due to increasing carotid intima media thickness as a risk factor of cardiovascular diseases. But few studies have been done on the role of non-alcoholic fatty liver as an independent risk factor for carotid intima media thickening. The present stud...

Background: Non-alcoholic fatty liver disease is one of the most important chronic liver disorders worldwide. Adipokines are polypeptide hormones that participate in the pathogenesis of non-alcoholic fatty liver disease. Adiponectin is an adipokine that stimulates fatty acid oxidation in muscle and plays a role in the development of insulin sensitivity. This study aimed to investigate the assoc...
