Unraveling the Relationship Between Itching, Scratch Scales, and Biomarkers in Children With Alagille Syndrome.

ABSTRACT: Pruritus is a debilitating symptom for patients with Alagille syndrome (ALGS). In a previously reported trial of maralixibat, an investigational antipruritic agent, itching was assessed using a digital diary based on twice-daily caregiver observation of itching severity (Itch Reported Outcome, ItchRO[Observer]). The goal of this study was to characterize pruritus in participants with ALGS at baseline in this trial, as assessed by the ItchRO instrument and the physician-observed clinician scratch scale (CSS), relative to biomarkers putatively associated with pruritus and health-related quality of life assessment. Thirty-seven participants with ALGS (median age of 6 years; range 1-17 years) were enrolled. No association was identified between CSS and ItchRO(Obs) (r = 0.22, P =
