We did not find any correlation between leptin levels and pituitary-thyroid axis in this control population. The correlation between leptin and thyroid volume in females is probably a consequence that leptin and thyroid volume are regulated in parallel by variables relating to anthropometry and body composition.

The study shows that the ultrasonographic thyroid volume at 3 and 6 months after low-dose 131I treatment for GD hyperthyroidism could be a reliable prognostic factor of thyroid function outcome in the first year after treatment, and also reveals that the changes in the thyroid echogenicity and in the immunological markers of GD have no prognostic value.
