Non-alcoholic fatty liver disease (NAFLD) is increasingly recognized as the most common cause of chronic liver disease worldwide. It has been shown that NAFLD has a strong association with metabolic syndrome and its component like insulin resistance (IR). Cardiovascular disease has a relation with NAFLD. Platelet volume is an indicator of platelet function and activation. Mean platelet volume (MPV) has been reported as a risk factor for atherothrombosis. In our study, we aimed to investigate the relation of MPV with NAFLD and IR in the NAFLD patients. A total of 54 patients with histologically proven NAFLD and 41 healthy age-matched control subject were enrolled in this study. The NAFLD subjects were divided into two subgroups: 42 patients in the insulin resistant group (median age 39.5, females 22 [52%]) and 12 patients in the insulin sensitive group (median age 38, females 5 [41.7%]). MPV were significantly higher in the NAFLD group in univariate analysis (p< 0.05). In the NAFLD patients, we did not find any relation between steatosis grade, lobular inflammation, hepatocellular ballooning, NAFLD activity score and fibrosis with MPV value. Among the insulin resistant and sensitive groups in the NAFLD patients MPV values were similar. The results of this study showed that MPV, an indicator of platelet activation, increased in biopsy proven NAFLD patients but MPV is not correlated with the increase of IR in NAFLD patients. MPV is not related with inflammation and steatosis degree, hepatocellular ballooning and fibrosis in NAFLD patients.
