BCR-ABL tyrosine kinase inhibitors (TKIs) are highly effective molecules in the treatment of CML. Unfortunately, these novel therapeutic agents are accompanied by various side effects, and haematological, cutaneous and metabolic abnormalities are among the most prevalent.

Background/aims: Nonalcoholic fatty liver disease is related to obesity, metabolic syndrome, and insulin resistance. Nonalcoholic fatty liver disease and metabolic syndrome may also be encountered in non-obese, non-diabetic individuals, and there are no published data about the prevalence of these conditions in non-obese, non-diabetic Turkish subjects. We aimed to determine the difference between non-obese, non-diabetic nonalcoholic fatty liver disease patients and healthy controls in terms of insulin resistance and metabolic syndrome in Turkish subjects.

Background: Platelet activation and aggregation play key roles both in the pathogenesis of atherosclerosis and in the developmentof acute thrombotic events. Platelet volume is a marker of platelet activation and function, and is measured usingmean platelet volume (MPV).

Aim: To determine the relationship between MPV and angiographic Gensini and SYNTAX scores, which give information about the severity and complexity of coronary artery disease (CAD).
