Safety of new DAAs for chronic HCV infection in a real life experience: role of a surveillance network based on clinician and hospital pharmacist.

BACKGROUND: Direct Antiviral Agents (DAAs) for HCV therapy represents a step ahead in the cure of chronic hepatitis C. Notwithstanding the promising results in several clinical trials, few data are available on adverse effects in real life settings.

METHODS: We have evaluated 170 patients with persistent infection and on those eligible to treatment we have followed up them through a network managed by clinician and hospital pharmacist.

RESULTS: According to our data we have found that 41% (32 out of 78) of enrolled patients experienced adverse reactions, of these 40% were in those under 65 years while 60% was in patients older than 65 years, SVR was achieved in 88% of the patients (including drop-out). We had 4 drop-out treatment due to major adverse reaction (heart and lung related).

CONCLUSION: Even if new antiviral drugs seem to be promising, according to SVR, they require careful follow-up, possibly managed by clinician and hospital pharmacist, to avoid unrecognized side effects which may affect adherence and the real impact of these drugs on chronically infected subjects.
