OBJECTIVE
To investigate the possible involvement of hepatocyte growth factor in arteriosclerotic lesions, by studying the relationship between serum concentrations of hepatocyte growth factor and grades of retinal arteriosclerosis.
METHODS
We measured the blood pressure, body mass index, serum concentrations of total cholesterol, high-density lipoprotein cholesterol, triglycerides, creatinine, uric acid, total protein, aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, gamma-glutamyltranspeptidase, alkaline phosphatase, and hepatocyte growth factor, erythrocyte counts, hemoglobin concentration, and hematocrit levels of 112 adults. Serum concentrations of hepatocyte growth factor were measured by a specific enzyme-linked immunosorbent assay. For each subject, photographs of both optic fundi were taken, and the grade of arteriosclerotic changes in the retinal arteries was evaluated according to Scheie's classification.
RESULTS
Individuals with more advanced grades of arteriosclerotic changes had higher serum hepatocyte growth factor values (grade 0, 0.056 +/- 0.004 ng/ml, n = 86; grade 1, 0.132 +/- 0.026 ng/ml, n = 17, P < 0.01, versus grade 0; grade 2-3, 0.271 +/- 0.023 ng/ml, n = 9, P < 0.01, versus grades 0 and 1). The serum hepatocyte growth factor concentrations were also correlated significantly to the serum uric acid concentrations (r = 0.230, P = 0.015) and erythrocyte counts (r = 0.299, P = 0.001), but not to the systolic and diastolic blood pressures, and other physical and humoral parameters.
CONCLUSIONS
Serum hepatocyte growth factor levels are thought to indicate the presence or development of arteriosclerotic lesions and may be a useful biochemical parameter for estimating the development of systemic arteriosclerosis irrespective of blood pressure levels.
