IL6 and thyroiditis: The thyrotoxic state can be sub-classified as type I amiodarone-induced thyrotoxicosis (AIT), usually associated with a pre-existing thyroid condition (e.g., nodular goiter in iodine-deficient areas), or type 2 AIT (drug-induced), presenting with a previously normal thyroid as thyroiditis or inflammation by interleukin-6 stimulation.
