Vascular endothelial growth factor level in chronic liver diseases

ABSTRACT

Ninety individuals [76 males and 14 females] were classified into four groups. G1 [control group] included 20 healthy individuals, G2 [chronic hepatitis group] included 20 patients, G3 [liver cirrhosis group] included 30 patients and G4 included 20 patients with HCC. All groups were subjected to clinical examination, abdominal ultrasonography, complete blood picture, HCV antibodies, HRs Ag and function tests [total and direct bilirubin, total plasma proteins and albumin, prothrombin time and concentration and liver enzymes AST, ALT and ALP]. Patients of G3 and G4 were classified according to Child Pugh classification into A, B and C. Upper endoscopic examination was done for 36/50 patients with chronic hepatitis or HCC. Circulating VEGF levels were determined by ELISA. There was statistically higher significant levels of circulating VEGF in G1, G2 and G3 than in the controls. There was a statistically significant higher level of circulating VEGF in G4 than in G3 and G4 and a statistically negative significant correlation between VEGF levels and platelet count in G2. There were no significant correlation between VEGF and the grade of esophageal varices in G3 and G4 and no significant correlation between VEGF and upper GIT bleeding or spider naevi [vascular skin changes] in G2. A statistically significant correlation was found between VEGF and degree of hepatic dysfunction
