TLDR Vitiligo is not linked to coeliac disease, but a small number of alopecia areata patients may have it, suggesting they should be tested for coeliac disease.

In a 1997 study, 198 patients with vitiligo and 232 patients with alopecia areata were tested for coeliac disease markers, antigliadin (AGA) and antiendomysial antibodies (EmA). None of the vitiligo patients had positive results for IgA antibodies, indicating no correlation between vitiligo and coeliac disease. However, 2 alopecia areata patients (1%) tested positive for IgA HUC-EmA and IgA IFL-AGA, and subsequent duodenal biopsies confirmed coeliac disease. One of these patients experienced hair regrowth after starting a gluten-free diet. The study concluded that while vitiligo is not associated with coeliac disease, there is a higher prevalence of coeliac disease in patients with alopecia areata, suggesting that routine screening for gluten-sensitive enteropathy should be considered for these patients.

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.
