Response-guided treatment with drug telaprevir can be shortened to 6 months for many.

University of Cincinnati research published in the Sept. 14, 2011, advance online edition of the New England Journal of Medicine shows that patients with hepatitis C who took a combination medication—a telaprevir-based regimen that is commonly used to treat the illness—for 24 weeks were cured.

In this week's PLoS Medicine, David Booth of the University of Sydney, Australia and colleagues show that genotyping hepatitis C patients for the IL28B, HLA-C and KIR genes substantially improves doctors' ability to predict whether or not patients will respond to antiviral treatment.
