The Claim

JAK inhibitors may reduce thyroid peroxidase antibody levels in patients with Hashimoto thyroiditis, suggesting a potential immunomodulatory effect on thyroid autoimmunity.

In plain English

In patients with Hashimoto thyroiditis, JAK inhibitors might lower levels of thyroid peroxidase antibodies, which could indicate an effect on the immune response targeting the thyroid.

See the scientific wording

JAK inhibitors may reduce thyroid peroxidase antibody levels in patients with Hashimoto thyroiditis, as observed in a single case following treatment for alopecia universalis, suggesting a potential immunomodulatory effect on thyroid autoimmunity.

  1. Study: Resolution of Hashimoto thyroiditis with Janus kinase inhibitor therapy in a patient with alopecia universalis

    A woman with two autoimmune conditions took a drug that helps with hair loss, and her thyroid antibodies dropped so much that she didn’t need thyroid medicine anymore. This suggests the drug might also help calm down the immune system’s attack on the thyroid.
