What is PASI in dermatology?
Hear this out loudPauseThe Psoriasis Area and Severity Index (PASI) is a quantitative rating score for measuring the severity of psoriatic lesions based on area coverage and plaque appearance. Add together each of the 3 scores for each body region to give 4 separate sums (A).
How is PASI psoriasis calculated?
Hear this out loudPauseCalculation. The body is divided into four sections (head (H) (10% of a person’s skin); arms (A) (20%); trunk (T) (30%); legs (L) (40%)). Each of these areas is scored by itself, and then the four scores are combined into the final PASI.
What is absolute PASI score?
Hear this out loudPauseWhen an absolute PASI score exceeds 5, it usually indicates that an alteration of treatment is needed regardless of the baseline value. For example, in patients with a higher baseline PASI score (PASI > 20), those who achieve a PASI 75 response may still have significant levels of persisting psoriasis.
Who developed PASI score?
Hear this out loudPauseThe PASI was developed by Fredriksson and Pettersson in 1978 as an objective means to measure the effectiveness of a retinoid during the course of the study. 3 In several subsequent studies it became apparent that the BSA measurement is one of the major limitations of the PASI.
What is a bad PASI score?
Hear this out loudPauseThe PASI is a widely used instrument in psoriasis trials that assesses and grades the severity of psoriatic lesions and the patient’s response to treatment. It produces a numeric score ranging from 0 to 72. In general, a PASI score of 5 to 10 is considered moderate disease, and a score over 10 is considered severe.
What does PASI 75 mean?
Hear this out loudPauseA 75% reduction in the Psoriasis Area and Severity Index (PASI) score (PASI 75) is the current benchmark of primary endpoints for most clinical trials of psoriasis. Many consider this endpoint to be too stringent as it places potentially useful therapies at risk of failing to demonstrate efficacy.

PASI combines the assessment of the severity of lesions and the area affected into a single score in the range 0 (no disease) to 72 (maximal disease).
How does PASI 75 work in clinical trials?
A psoriasis treatment is deemed effective during clinical trials if a large number of patients are judged to be “PASI 75 responder” as a result of the medication or therapy. PASI 75 means that the person’s PASI score dropped by 75 percent as a result of the psoriasis treatment.
What’s the difference between PASI 75 and PASI 90?
Rates of PASI 75 responses have not differed much between newer and older drugs, but new agents, such as the anti-IL-17 and anti-IL-23 drugs have led to dramatically higher rates of PASI 90 response, he said. “Isn’t it our obligation to set the expectations correctly for patients?” Pariser asked.
