Weekly epistaxis duration as an indicator of epistaxis severity in hereditary hemorrhagic telangiectasia—Preliminary results from a randomized controlled trial

Abstract

There is great interest in developing and studying novel therapies for epistaxis in hereditary hemorrhagic telangiectasia (HHT) given its associated morbidity and impact on patients quality of life. Several recent randomized controlled trials (RCTs) have been negative, likely attributed to poorly characterized outcome measures. This study reported on and evaluated an epistaxis outcome measure, weekly epistaxis duration (WED) in an ongoing RCT, with the aim of better characterizing the measurement of epistaxis for clinical trials.
