New dolutegravir resistance pattern identified in a patient failing antiretroviral therapy.

Introduction: The most recently approved antiretroviral, the integrase inhibitor dolutegravir (DTG), is described to be a very potent drug with a unique resistance profile, but a certain degree of cross-resistance to RAL or EVG induced drug resistance, which is mediated mainly by integrase mutations at positions 140 and 148. The impact of a single N155H mutation to DTG resistance is described to be minor. However, there is only rare data available about the impact of N155H in the context of secondary site integrase mutations.

Pilot study of interferon alpha high-dose induction therapy in combination with ribavirin for chronic hepatitis C in HIV-co-infected patients.

Twenty-three HIV/hepatitis C virus (HCV)-co-infected patients received dose-escalated IFN-alpha (5 MIU/day) induction therapy for 10 weeks, followed by 36 weeks of thrice-weekly IFN-alpha treatment (5 MIU), both in combinations with ribavirin. Sustained HCV clearance was observed in three patients. Nine patients discontinued the study aas a result of adverse reactions such as anaemia, pancreatitis and depression.
