We found that the activity of circulating PAF-AH in patients diagnosed with hepatitis B was positively correlated with TBIL, TBA, ALT, AST, TG, and apoB, negatively correlated with ChE, HDL-c, and apoAI, and not correlated with Glu, BMI, Tch, and LDL-c. This evidence concerns the gene APOA1 and hepatitis B virus infection.
