  • Summary

    » New EASL HBV guidelines

    » For HBV therapy TAF offers a new treatment option with

    significant less potential for bone and renal toxicity.

    » Of note 20% of all HCV infections globally are estimated to be

    diagnosed in 2017. Under consideration of the 2030 goal of 90%

    HCV infections diagnosed globally there still is a long way to

    go.

    » HCV treatment coverage worldwide is still below 10%

    emphasizing the need of considerable HCV treatment scale-up

    to reach the WHO 80% HCV treatment target in 2030.

    » New pangenotypic regimens can be expected which will allow at

    least for some combinations shorter treatment durations as well

    as offer treatment options who have failed prior DAA therapy

    and have 2-drug class resistance
