We found that in hepatitis B–positive patients, PAF-AH activity correlated positively with TBIL, TBA, ALT, AST, TG, and apoB (Spearman correlation coefficients [r-values] = 0.633, 0.559, 0.176, 0.332, 0.276, and 0.348, respectively; all P < 0.05), correlated negatively with ChE, HDL-c, and apoAI (r = −0.273, −0.493, and −0.530, respectively; all P < 0.05), and did not correlate with Glu, body mass index (BMI), Tch, or LDL-c levels (all P > 0.05). This evidence concerns the gene APOB and hepatitis B virus infection.
