serum levels of vascular endothelial growth factor in chronic obstructive pulmonary disease
Authors
abstract
background :chronic obstructive pulmonary disease (copd) is a third leading cause of death. methods : in this case control study, we prepared 5 cc bloods from the antecubital vein of 100 copd patients and 40 healthy individuals as control group. vascular endothelial growth factor (vegf) expression protein level was measured by elisa in both groups. results : we found that concentration of vegf in blood serum of patients with copd (189.9±16pg/ml) was significantly higher than the control group (16.4±3.48pg/ml) (p< 0.001). while vegf serum level in emphysematous patients wasn’t significantly different with control group (p=0.07). furthermore vegf serum level in copd patients was proportionally increased with severity of disease (p< 0.001). besides all copd patients, regardless of their smoking status, were experienced significantly higher levels of vegf than healthy ones (p=0.001 z=4.3). conclusion : our results suggest vegf serum concentration as the sensitive index for severity and activity of copd and its prognosis.

BACKGROUND Impaired vascular endothelial growth factor (VEGF) signaling causes emphysema in animal models. In chronic obstructive pulmonary disease (COPD) patients, alterations in VEGF tissue expression have been observed. We hypothesize that circulating VEGF may be a biomarker to phenotype COPD patients. OBJECTIVE The aim of this study was to investigate VEGF serum levels in stable and exace...

Chronic obstructive pulmonary disease (COPD) is a disorder which encompasses not only morphological changes in parenchyma, central and peripheral airways but also in structural and functional changes of pulmonary vessels. The role of angiogenic factors leading to abnormal pulmonary vessel remodeling remains unclear. We have investigated a cytokine vascular endothelial growth factor (VEGF) known...
