[Vascular endothelium-related factors and atherosclerosis/arteriosclerosis: serum hepatocyte growth factor as a possible indicator of vascular lesions].
To investigate the possible involvement of hepatocyte growth factor (HGF) with vascular lesions, we studied the relationship between serum HGF concentrations and the grades of retinal arteriosclerosis, coronary atherosclerosis proliferative changes in the retina of diabetic subjects, and activities of systemic vasculitis. Individuals with more advanced grades of retinal arteriosclerotic change showed higher serum HGF values (grade 0, 0.053 +/- 0.005 ng/ml ; grade 1, 0.144 +/- 0.022 ng/ml ; grade 2, 0.338 +/- 0.36 ng/ml ; grade 3, 0.526 +/- 0.051 ng/ml). The serum HGF concentration was increased in subjects with single- (0.200 +/- 0.012 ng/ml, double- (0.334 +/- 0.018 ng/ml) or triple- (0.379 +/- 0.022 ng/ml) vessel coronary heart diseases, compared with that in subjects with intact coronary arteries (0.112 +/- 0.008 ng/ml). Serum HGF in diabetes without retinopathy was lower than that in nondiabetic subjects (0.041 +/- 0.003 ng/ml vs 0.080 +/- 0.010 ng/ml, p < 0.05), but did not differ from that in other diabetic subjects with background retinopathy (0.058 +/- 0.007 ng/ml) or preproliferative retinopathy (0.048 +/- 0.010 ng/ml). Serum HGF was increased in patients with proliferative retinopathy without photocoagulation (0.213 +/- 0.025 ng/ml, p < 0.01), but not in those with photocoagulation (0.040 +/- 0.008 ng/ml). Serum HGF concentration was increased (p < 0.01) during the acute phase of Schönlein-Henoch purpura (0.31 +/- 0.15 ng/ml), a systemic vasculitis, but it returned to control levels during the remission phase (0.11 +/- 0.10 ng/ml). Increased serum HGF may be involved in the pathogenesis of arteriosclerosis/atherosclerosis, retinal neovascularization, or vasculitis, and measurement of serum HGF may be a useful test for predicting these vascular lesions.
