A strong association was noted between IL28B genotype and pretreatment normalized ALT (median 2.4, 2.3, and 1.6 for CC, CT, and TT respectively) and as well as APRI, a biomarker of liver fibrosis [23], (median 0.7, 0.6, and 0.5 for CC, CT, and TT respectively) among HCV genotype 3 infected patients, with homozygous TT carriers having the lowest levels (p<0.0001 and p = 0.001 respectively, Kruskal-Wallis test; Figure 1). Here, GPT is linked to Hepatic fibrosis.
