AIH is a complex diagnosis partly because there is no anatomic criterion (i.e. ’gold’) standard. The revised (1999), conventional AIH score solves this problem by defining the diagnosis, though some would say the recently developed, more specific, simplified version offers a preferred alternative.
We are unaware of validated management algorithms using the AIH score.
Overlap with multiple conditions is always a concern to consider, despite score findings, and ‘definite’ scores are considerably more predictive than ‘probable’ scores.
