ABSTRACT
Introduction:
The aim of the current study was to examine the difference between patients detected with nonalcoholic fatty liver disease (NAFLD) and healthy subjects in terms of serum angiopoietin-like protein (ANGPTL) 2 and ANGPTL6 levels and to evaluate the correlation between ANGPTL2 and ANGPTL6 levels and liver enzyme levels, fasting glucose, lipid levels, and steatosis degree on ultrasonography (USG).

Material and methods:
A total of 159 participants were included in the study. The participants were divided into 3 groups depending on the steatosis degree on USG and serum alanine aminotransferase (ALT) levels: the NAFLD group with increased ALT, the NAFLD group with normal ALT, and the healthy control group. The groups were compared in terms of biochemical and ultrasonographic findings, insulin resistance, metabolic syndrome (MetS), and anthropometric parameters.

Results:
There was no significant difference between NAFLD patients and healthy subjects with respect to serum ANGPTL2 and ANGPTL6 levels (p > 0.05). ANGPTL2 levels did not correlate with serum, biochemical, or ultrasonographic findings, or anthropometric parameters (p > 0.05). A positive correlation was found between serum ANGPTL6 levels and fasting blood glucose, ALT, alkaline phosphatase, -glutamyl transpeptidase, fasting insulin, and HOMA-IR levels.

Conclusions:
While our findings suggest no relationship between serum ANGPTL2 and ANGPTL6 levels and NAFLD, ANGPTL6 levels may be related to metabolic and biochemical parameters. The effects of ANGPTL2 and ANGPTL6 in the pathogenesis of NAFLD should be investigated further.
