Hepatitis C Research and News.
The identification of the genetic variation in the IL28B gene region as a predictor of genotype 1 chronic HCV treatment outcome is an exciting discovery. It sheds new light on virus–host interaction, and appears to have immediate clinical use as a diagnostic tool, providing potentially helpful information to both patients and clinicians considering therapy with PEG-IFN plus RBV. It is therefore a step towards a personalized approach to anti-HCV therapy.
However, the treatment paradigm for genotype 1 HCV is about to change with the introduction of direct antivirals. The role of the IL28B variation in this setting as well as determining the duration of therapy required in these favourably genetically determined individuals with both current two-drug and future three-drug regimens requires semi-urgent investigation."
