Clinical significance of circulating hepatocyte growth factor, a new risk marker of carotid atherosclerosis in patients with Type 2 diabetes.
ABSTRACT Recent studies have provided increasing evidence that hepatocyte growth factor (HGF) has a pathophysiological role in the development of diabetic complications. We set out to determine the relationship between serum HGF and risk factors for macroangiopathy including carotid atherosclerosis. Carotid atherosclerosis is an established and important risk factor for both cerebral and coronary artery diseases.
We studied 89 patients (48 males, 41 females, mean age 62.5 +/- 10.3 years) with Type 2 diabetes (DM).
Serum levels of HGF correlated positively with both intimal-media thickness (IMT) (r = 0.24, P = 0.0248) and plaque score (r = 0.27, P = 0.0126). In multiple regression analysis, serum HGF was associated independently with IMT (standardized beta = 0.28, P = 0.0499). We also found that both IMT and plaque score were higher in patients with ischaemic heart disease (IHD) than in patients without IHD, and that plaque score in patients with lacunar infarcts was higher than in patients without lacunar infarcts.
Serum HGF concentration may be a new marker of atherosclerotic complications in patients with Type 2 DM.
