Dermatology Quality of Life Index
Lasso di tempo: baseline and weeks 1, 12, 24
|
Assesses the degree of pain, the number of flares, and the impact on daily life .
Dermatology disease agnostic, not specific for HS
|
baseline and weeks 1, 12, 24
|
|
Hidradenitis Suppurativa Investigator Global Assessment (HS-IGA)
Lasso di tempo: baseline and weeks 1, 12 ,24
|
Response is defined as at least a 2-point reduction in HS-IGA score relative to baseline.
|
baseline and weeks 1, 12 ,24
|
|
Central sensitization Index (CSI)
Lasso di tempo: baseline and weeks 1, 12, 24
|
measures centrally processed pain signals.
The participant scores each answer on a scale of 0 (never) to 4 (always).
A score of more than 40 indicates the presence of central sensitization.
|
baseline and weeks 1, 12, 24
|
|
Numeric Rating Scale -30
Lasso di tempo: baseline and weeks 1, 12, 24
|
The numeric rating scale (NRS) is a pain scale that asks a patient to rate their pain on a scale of 0 to 10 where a higher score indicates a higher pain level.
It's a common tool used in healthcare to assess pain severity.
|
baseline and weeks 1, 12, 24
|
|
Hidradenitis Suppurativa Clinical Response (HiSCR)-50
Lasso di tempo: baseline and weeks 1, 12, 24

The International Hidradenitis Suppurativa Severity Score (IHS4) is a validated tool that measures the severity of hidradenitis suppurativa (HS).
The IHS4 score is calculated by adding the number of nodules, abscesses, and draining tunnels, each multiplied by a weight A score of 3 or less indicates mild HS, 4-10 indicates moderate HS, and 11 or higher indicates severe HS.
The IHS4 is used to assess the severity of HS and to measure inflammatory lesions, such as draining tunnels.

|
Hidradenitis Suppurativa Area and Severity Index Revised
Lasso di tempo: baseline and weeks 1, 12, 24
|
The HASI-R method assesses HS severity in a manner that incorporates signs of inflammation and body surface area involved.
Scores range from 0-720 where a higher score indicates worse disease.

|
PainDETECT
Lasso di tempo: baseline and weeks 1, 12, 24
|
an assessment tool for neuropathic pain.
Scores range from -1 to 38.
A score of 19 or higher indicates neuropathic pain is likely.

|
Generalized Anxiety Disorder-7 (GAD-7)
Lasso di tempo: baseline
|
The GAD-7 (General Anxiety Disorder-7) measures severity of anxiety over a 2 week period.
Answers are scored from 0 to 3 ("not at all" = 0, "several days" = 1, "more than half the days" = 2, and "nearly every day"=3).
A score of 10 or higher is considered positive for anxiety.
