Summary

This pilot, genotype-stratified clinical trial aims to evaluate the safety and preliminary efficacy of combined selenomethionine and myo-inositol supplementation in patients with autoimmune thyroiditis (AIT), including Hashimoto's thyroiditis, who carry the Thr92Ala (rs225014) variant in the DIO2 gene. The study will compare changes in thyroid function tests, autoantibody titers, and clinical symptoms between two cohorts: (1) carriers (homozygous or heterozygous) of the Thr92Ala variant and (2) individuals without this variant ("wild-type"). The hypothesis is that patients with the "unfavorable" DIO2 genotype will experience greater improvements in TSH levels, the free T3/ free T4 ratio, and autoimmunity markers when receiving selenomethionine plus myo-inositol, potentially due to enhanced support of thyroid hormone conversion and reduced autoimmune activity.
