diffuse alopecia areata inflammatory infiltration CD8+ T cells serum IgE level patchy alopecia areata eosinophils hypersensitivity pathogenesis diffuse AA patchy AA IgE T cells

TLDR Diffuse alopecia areata involves more inflammation and higher allergy-related antibodies than patchy types.

The study compared 17 patients with diffuse alopecia areata (AA) to 37 with patchy AA and 27 healthy controls, revealing that diffuse AA is characterized by more intense inflammatory infiltration, especially by CD8+ T cells, and higher serum IgE levels. The average age of diffuse AA patients was 27, and their condition often began acutely in spring or summer, frequently following scalp itching. The increased infiltration and IgE levels suggest a hypersensitivity component in diffuse AA's pathogenesis. The presence of eosinophils was also noted as a potential diagnostic marker, although their exact role is unclear. The study's small sample size indicates a need for further research to better understand diffuse AA.

community Diffuse hair loss and scalp biopsies

in Research 692 upvotes 4 months ago

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
