International Psoriasis Councils’ Psoriasis Severity Reclassification Project aims to change the classification of psoriasis severity. IPC’s network of key opinion leaders agreed on a definition for each category of disease severity.
The IPC Disease Severity Working Group concluded that the objective measures of two commonly used clinical tools to determine psoriasis severity may not fully capture the impact of the disease on the individual in a new review published in the Journal of The Academy of Dermatology and Venerology (JEADV).
In moderate to severe psoriasis, there has been a long-lasting tradition to define outcome as a relative change from baseline PASI, with the classical PASI 75 being more recently replaced by PASI 90 or 100. However, this concept is dated, mainly due to the impressive development of anti-interleukin therapies and an increasing interest in real-world evidence.
