Patients with early virologic response (HCV RNA <25 IU/mL [detectable/undetectable in IL28BCC patients or undetectable in IL28B CT/TT patients] at Week 2 and undetectable at Weeks 4 and 8) were eligible to stop all treatment at the end of Week 12, otherwise PR therapy was continued to Week 24.
Levels of ISGs and IFNL2/3 mRNAs were lower in IFNL3rs12979860CC patients compared with non-CC patients, and in treatment responders, compared with nonresponders.
IL28BCC phenotype was associated with increased probability of achieving eRVR and SVR, whereas previous non-response was associated with low eRVR and SVR rates.
The correlation between IL28B.rs12979860 genotypes and CMI is suggestive of a possible important role of CMI in favoring hepatitis C virus clearance in CC patients.
Among IL28B-CC patients (n = 196), the rs429358 (defines ε4 isoform) and TOMM40 '523' S polymorphisms were associated with 12 % of variance in ApoB levels.
