Table 2.

Effect of Steroid Exposure and Elevated Thyroid Antibodies on Levothyroxine Dose

Antibody and steroid exposure versus dose <1 μg/kg (n/10) 1–1.6 μg/kg (n/17) >1.6 μg/kg (n/9)
Ab+/steroid+, (n) 1 4 0
Ab+/steroid−, (n) 1 4 4
Ab−/steroid+, (n) 6 3 2
Ab−/steroid−, (n) 2 3 1

Any steroid exposure either intravenous or oral physiological or supraphysiological, anytime during the course of thyroiditis was documented as positive. Antibodies (Ab) detected were antithyroid peroxidase antibodies and/or antithyroglobulin antibodies.
