Influence of high tissue-absorbed dose on anti-thyroid antibodies in radioiodine therapy of Graves' disease patients.

Background: The results of radioactive iodine (RAI) treatment for Graves' disease (GD) are related to the choice of diagnostic and dosimetry protocols, the steroid protection used, and the subsequent 131I dose. The effect of a high tissue-absorbed dose on the level of anti-thyroid antibodies (ATA) has been rarely considered.

Objectives: To estimate the effect of the first RAI therapy with a dose of 250 Gy on anti-thyreoperoxidase (anti-TPO) and anti-thyroid-stimulating hormone (TSH) receptor thyrotropin receptor antibody - TRAb levels in GD patients.

Semi-quantitative method for the assessment of focal lesions in parathyroid scintigraphy with relation to histopathology: a prospective study.

Bbackground: The aim of this paper was to analyse our own semi-quantitative method of assessing focal lesions localised in pre-operative diagnostic scintigraphy of primary hyperparathyroidism (PHPT) using 99mTc-MIBI with washout and comparing these data with the result of the histopathological examination (HP).

Material And Methods: A total of 40 (37 female, 3 male, average age 58.7 years) patients with a suspicion of PHPT were enrolled for prospective analysis.

Thyroid Peroxidase Antibodies in Non-Autoimmune Hyperthyroidism Treated with Radioactive Iodine.

Earlier studies suggest increased serum levels of thyroid peroxidase antibodies (TPOAb) in some cases with non-autoimmune hyperthyroidism. The aim of the study was to assess the incidence of hypothyroidism in patients with nodular toxic goitre and toxic adenoma at 12 months after radioactive iodine therapy in the relation to TPOAb levels. The study comprised 100 patients (83 females; 17 males) treated with radioactive iodine therapy.
