Study Details

Study Description

Brief Summary

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.

Condition or Disease Intervention/Treatment Phase

    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.

    Arms and Interventions

    Arm Intervention/Treatment
    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.

    Outcome Measures

    Primary Outcome Measures

    1. PAI-1 expression level in scalp skin biopsy samples [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.
