Generalised pustular psoriasis Area and Severity Index (GPPASI)

The GPPASI combines the scores for each body region (head, trunk, upper and lower limbs) for erythema, pustules, and scaling (desquamation) with the percent involvement of these areas

Severity Scale

Generalized Pustular Psoriasis Area and Severity Index (GPPASI)

  • The GPPASI was developed based on the Psoriasis Area and Severity Index (PASI), a measure used to assess the area and severity of psoriatic lesions in patients with psoriasis1
  • The induration component was replaced with the pustules2
  • GPPASI provides a numeric scoring for a patient's overall GPP disease state, ranging from 0 to 72

Calculation of total GPPASI score3

[(E+P+D)x Area] x0.1 (head)]+ [(E+P+D)x Area] x0.1 (upper limb)] +[(E+P+D)x Area] x0.1 (trunk)] [(E+P+D)x Area] x0.1 (lower limb)]

Severity Scale

Generalized pustular psoriasis physician global assessment (GPPGA)

  • The GPPGA total score is determined based on the mean composite score1
  • Each component is graded separately and the average is calculated

Calculation of total GPPGA score

[(E+P+D)/3] (head)]+ [(E+P+D)/3] (upper limb)] +[(E+P+D)/3] (trunk)] [(E+P+D)/3 (lower limb)]
