alopecia areata autoimmune thyroid disease thyroid autoantibodies HLA haplotypes class II HLA haplotypes AA thyroid antibodies

TLDR Alopecia areata is linked to thyroid autoimmunity but not type 1 diabetes.

The study investigated the association of alopecia areata (AA) with thyroid and islet autoimmunity in 126 patients. It found that autoimmune thyroid disease was the most frequent autoimmune condition associated with AA (10.0%), while type 1 diabetes was not observed. Patients with AA had significantly higher prevalence of thyroid-related autoantibodies compared to controls, but similar prevalence of islet-related autoantibodies. The study also identified specific HLA haplotypes that were either protective or susceptible to these autoimmune diseases, indicating that AA was associated with thyroid autoimmunity but not islet autoimmunity, and this association was influenced by class II HLA haplotypes.

nkrata in Research 830 upvotes 1 year 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.
