Study Notes
- Gluten-free diet has a favorable effect on thyroid autoimmunity.
- Improvement in vitamin D status is one of the mechanisms responsible for this effect.
- Patients on a gluten-free diet had low levels of 25-hydroxyvitamin D.
- Gluten-free diet increased levels of 25-hydroxyvitamin D and correlated with changes in TPOAb titers.
- Exogenous vitamin D reduced thyroid antibody titers in women with thyroid autoimmunity.
- TPOAb are more sensitive than TgAb in the diagnosis of autoimmune thyroid disease.
- Correlations between TPOAb titers and 25-hydroxyvitamin D levels were moderate.
- Other mechanisms may contribute to the favorable effect of the gluten-free diet.
- Improvement in selenium status may be one of these mechanisms.
- Preparations of selenium were found to reduce thyroid autoimmunity by inhibiting a secretory function of human T cells.
