Methods for causality assessment of idiosyncratic drug‐induced liver injury

Abstract

AbstractThe diagnosis of idiosyncratic drug‐induced liver injury (DILI) is a challenging task due to the lack of specific features or definitive diagnostic tools. A minimum of clinical and pharmacological information is required, together with laboratory and imaging tests to exclude other causes of liver injury. Several standardized methods have been developed to support clinical judgement and establish causality assessment, the most widely used being the Roussel Uclaf Causality Assessment Method—RUCAM—and structured Expert Opinion. More recently, an evidence‐based, revised RUCAM, Electronic Causality Assessment Method—RECAM—has been developed and, although still a work in progress, may replace RUCAM scoring in the future. International collaborative networks and ongoing research efforts are key to advancing biomarker qualification and validation and developing new in vitro patient‐based methods that will help improve DILI diagnosis and move towards a personalized medicine approach.
