ABSTRACT To investigate oxidative stress in chronic hepatitis B (CHB) patients with elevated serum total bilirubin (TBIL).
75 CHB patients with elevated serum TBIL were enrolled in the present study. A, B, C, D and E group were defined. Serum Malondialdehyde (MDA), Xanthine Oxidase (XOD), Vitamin C (V(C)) and Vitamin E (V(E)) were determined. The control group contained 11 healthy donors and the carrier group contained 16 Hepatitis B surface antigen (HBsAg) carriers.
The concentrations of MDA and XOD were significantly higher in each group of patients than in the control (P < 0.05), while V(C) and V(E) were significantly lower (P < 0.05). The concentration of XOD was significantly higher in the carrier group than in the control (P < 0.05), while MDA, V(C) and V(E) were not significantly different (P > 0.05). The concentrations of MDA and XOD were significantly positively correlated with TBIL (r = 0.670, P < 0.01; r = 0.737, P < 0.01, respectively) in the patients, while V(C) and V(E) were significantly negatively correlated with TBIL (r = -0.463, P < 0.01; r = -0.247, P < 0.05, respectively). The concentration of MDA was significantly different among all the groups in the patients except the comparison between group A and group B. The concentration of XOD was significantly different between group A, B, C and group D, E (P < 0.05). The concentration of V(C) was significantly different between group A and group D, E and between group B, C, D and group E (P < 0.05). The concentration of V(E) was significantly different between group A, B and group E (P < 0.05).
There was a disturbance between oxidative stress and anti-oxidative ability in CHB patients with elevated serum TBIL. Oxidative stress became more serious along with the increasing of serum TBIL. In HBsAg carriers, oxidative stress level was low. The results suggest antioxidant treatment for CHB patients with elevated serum TBIL may help to improve the effect of therapy.
