Changes of Circulating Platelet-Derived Growth Factor and Granulocyte Colony-Stimulating Factor in Patients with Condyloma Acuminatum

摘要

Objective: To study the expression levels of platelet-derivedgrowth factor (PDGF) and granulocyte colony-stimulatingfactor (G-CSF) in peripheral blood and their role in thepathogenesis of Condyloma acuminatum (CA). Methods: Sera were taken from 70 patients with Condylomaacuminatum and compared with 35 healthy controls. PDGFand G-CSF in serum were quantitated using a dual antibodysandwich enzyme-linked immunoabsorbent assay (ELISA). Results: Serum concentrations of PDGF and G-CSF weresignificantly increased in patients with Condylomaacuminatum (CA) compared to controls (P<0.001 and P<0.005respectively). Serum levels of PDGF and G-CSF correlatedwith clinical severity of CA, but no significant difference wasobserved between different duration of disease groups. Asignificant positive correlation was noticed between neutrophilcount and G-CSF levels ( γ=0.38, P<0.001), and the neutrophilcount showed no significant correlation with PDGF. Conclusion: The results indicated that increased expressionof PDGF and G-CSF in peripheral blood might be involved inpathogenesis of CA.
