The Claim
In patients with Graves' disease, elevated plasma levels of free triiodothyronine (FT3) and free thyroxine (FT4) are positively correlated with elevated plasma levels of the Th17-associated cytokines IL-17a, IL-23, and IL-10, independent of autoantibody levels.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In people with Graves' disease, higher levels of two thyroid hormones, FT3 and FT4, are associated with higher levels of certain inflammatory signaling molecules called IL-17a, IL-23, and IL-10, regardless of the levels of autoantibodies present.
See the scientific wording
In patients with Graves’ disease, higher levels of free triiodothyronine (FT3) and free thyroxine (FT4) are positively correlated with plasma levels of Th17-associated cytokines IL-17a, IL-23, and IL-10, suggesting that the severity of hyperthyroidism may be linked to the activity of this inflammatory pathway independently of autoantibody levels.
What the research says
1 studyStudy: Plasma levels of Th17‐associated cytokines and selenium status in autoimmune thyroid diseases
This study found that when Graves' disease patients have higher levels of thyroid hormones, they also tend to have higher levels of certain inflammation-related proteins, suggesting that how sick they feel may be tied to body-wide inflammation, not just their immune system attacking the thyroid.
