PAI-1 Expression in Non-scarring Hair Loss
June 7, 2022 updated by: Maria Colavincenzo, Northwestern University
Evaluating PAI-1 Expression in the Hair Follicles of Patients With Non-scarring Hair Loss.
This study will investigate whether subjects who suffer from hair loss have increased levels of PAI-1 compared to age-matched control subjects.
The level of PAI-1 expression will be determined in subjects without hair loss and in subjects with non-scarring hair loss, including androgenetic alopecia, telogen effluvium and alopecia areata.

Terminated
Detailed Description
This study will compare the levels of PAI-1 expression in subjects with different forms of non-scarring hair loss and in these subjects vs normal age-matched controls.
Hair loss subjects will have their Northwestern Memorial Hospital and Northwestern Medical Faculty Foundation medical records reviewed to ensure they meet inclusion and exclusion criteria.
All subjects will have a 4 mm punch biopsy on the scalp.
Tissue PAI-1 levels from scalp skin biopsies will be determined by immunohistochemical staining.
Samples will be kept for approximately 15 years, after which time unused samples will be destroyed.

Participation Criteria
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
Eligibility Criteria
Ages Eligible for Study
16 years to 58 years (Adult)
Accepts Healthy Volunteers
No
Genders Eligible for Study
All
Sampling Method
Non-Probability Sample
Study Population
All hair loss subjects will be recruited from patients seen at Northwestern Memorial Hospital or Northwestern Medical Faculty Foundation physicians offices.
Age-matched control subjects will be recruited by either 1) the use of flyers displayed in the hospital and surrounding community, or 2) will be identified during a clinic visit at Northwestern Memorial Hospital or Northwestern Medical Faculty Foundation physician offices.
Description
Inclusion Criteria:
- Age-matched control subjects who do not have a history of hair loss
- A clinical and pathologic diagnosis of androgenetic alopecia, telogen effluvium, alopecia areata or normal scalp skin
- All subjects must have given signed, informed consent prior to registration in study
Exclusion Criteria:
- History of previous hair transplantation
- Current and past use of medications topically on the scalp
- Clinical or pathologic diagnosis of a scarring alopecia
- History of inflammatory conditions of the scalp such as psoriasis

Group / Cohort |

Non-scarring hair loss
Patients seen at Northwestern Memorial Hospital or Northwestern Medical Faculty Foundation physician offices that have undergone evaluation for hair loss and have a diagnosis of androgenetic alopecia, telogen effluvium or alopecia areata.
|
Control
Age-matched controls who do not have a history of hair loss and have normal scalp skin without evidence of hair loss.

Time Frame |
---|---|---|
PAI-1 expression level in scalp skin biopsy samples
Time Frame: Baseline
|
Tissue PAI-1 expression levels will be determined by immunohistochemistry, a three-layer biotin-strepavidin system.
Positive PAI-1 expression per total tissue area will be quantified using the color-picker function in imaging software.The PAI-1 expression found in normal scalps will be compared to those found in scalps with hair loss.
