Autoimmune Bullous Skin Disorder Intensity Score (ABSIS) of Pfutze et al: Severity Subscore for Skin Involvement

Description

Pfutze et al developed the Autoimmune Bullous Skin Disorder Intensity Score (ABSIS) for evaluating a patient with pemphigus. It consists of three subscores, one of which deals with symptoms associated with eating and drinking. The authors are from Philipps-University in Marburg, Germany.

subscore for skin involvement =

= SUM(((percent of body area involved) * (percent body surface area for body area) * (weighting factor)) for all 7 body regions)

 

The sum for percent of body region involved should add up to 100%.

 

Interpretation:

• minimum score: 0

• maximum score: 150

• The higher the score the greater the skin involvement.
