| Abstract |
| Angiogenesis plays an important role in the progression of rheumatic disease. We measured the levels of vascular endothelial growth factor (VEGF) and hepatocyte growth factor (HGF) in sera from patients with rheumatic diseases and investigated whether these angiogenic factors would be useful in the evaluation of rheumatic diseases. Serum VEGF and HGF levels were determined using ELISA in 128 patients with rheumatic diseases and in 11 healthy controls. Serum VEGF and HGF levels were significantly higher in patients with rheumatic diseases compared to healthy controls [VEGF, 312 ± 20?pg/ml versus 61 ± 8?pg/ml (mean ± SE), P < 0.001; HGF, 935 ± 36?pg/ml versus 413 ± 49?pg/ml, P < 0.01]. Serum VEGF and HGF levels were significantly elevated in patients with adult Still's disease (VEGF, 1021 ± 258?pg/ml; HGF, 1500 ± 295?pg/ml) and were relatively increased in patients with active rheumatoid arthritis (RA) (VEGF, 359 ± 94?pg/ml) and systemic sclerosis (SSc) (VEGF, 356 ± 43?pg/ml; HGF, 1294 ± 224?pg/ml). HGF levels correlated with the clinical course and disease severity in rheumatic disease patients. VEGF levels correlated with the presence of Raynaud's phenomenon (P < 0.05), interstitial lung disease (ILD) (P < 0.05), and serum KL-6 levels (P < 0.01), whereas HGF levels correlated with cryoglobulinemia (P < 0.05), ILD (P < 0.05), serum C-reactive protein (CRP) (P < 0.05), thrombomodulin (P < 0.05), and KL-6 levels (P < 0.05) in rheumatic disease patients. VEGF levels correlated with the skin scores and KL-6 levels in SSc patients and also correlated with the disease activity of RA patients. These data suggest that serum VEGF and HGF levels are related to rheumatic disease activity and the presence of complications. Analysis of VEGF and HGF may be useful in the clinical evaluation of rheumatic disease patients. |
