Meteorin-Like Protein Levels Decrease in Patients With Acute Ischaemic Stroke.

INTRODUCTION

Ongoing research aims to investigate blood-based biomarkers and use them in acute ischaemic stroke (AIS) diagnosis and management of patients with AIS.

PURPOSE

The purpose of the present study was to investigate the meteorin-like protein (Metrnl) levels secreted by adipose tissue in patients with AIS.

METHODS

The study groups included healthy controls (n=30) and patients diagnosed with AIS via magnetic resonance imaging (MRI) in the emergency department (n=35) during the one-year period. The basic laboratory values and Metrnl, total antioxidant capacity (TAC), total oxidant status (TOS), and oxidative stress index (OSI) levels of the patients were compared. The Metrnl levels were measured using enzyme-linked immunosorbent assays.

RESULTS

In the present study, the Metrnl (p=0.001) and TAC (p=0.009) levels decreased significantly, whereas the TOS (p<0.001) and OSI (p<0.001) levels increased significantly in the patients with AIS compared to the healthy controls. Furthermore, a cut-off value of ≤1.63% meteorin-like protein rendered the sensitivity and specificity rates of 91.43% and 71.43%, respectively, in the patients with AIS. In addition, there was a significant negative correlation between the decreased meteorin-like protein levels and the infarct diameter in patients with AIS.

CONCLUSION

In patients with AIS, the meteorin-like protein levels decreased inversely with the infarct diameter, and at the same time, there was an increase in TOS and OSI levels and a decrease in TAC levels.
