Chronic HBV-infection (HBsAg(+)) was significantly associated with elevation of aminotransferases (210 ± 180 vs 97 ± 67 for ASAT and 130 ± 110 vs 85 ± 59 for ALAT, P = 0.018 and P = 0.024 respectively, Fig. 3b) indicating that, in its terminal phases, chronic infection with HBV is more active than hepatitis C in Ivory Coast. This evidence concerns the gene ABCB7 and hepatitis C virus infection.
