BACKGROUND The purpose of this study was to examine the incidence of sialadenitis and xerostomia within a year after radioactive iodine administration for thyroid remnant ablation after preparation with recombinant human thyroid-stimulating hormone (rhTSH) or levothyroxine (LT4 ) withdrawal. METHODS The study has included 121 patients, divided into 4 groups: group A (rhTSH = 100 mCi), group B...

OBJECTIVE The objective of this study was to determine whether the use of recombinant human TSH (rhTSH) to stimulate radioiodine uptake after thyroidectomy is as efficacious as a period of withholding thyroid hormones, while at the same time avoiding hypothyroidism, reducing sick leave time and shortening the hospital stay. DESIGN Our aim was to compare the standard procedure of differentiate...

OBJECTIVE Thyroid function abnormalities are common during treatment with tyrosine kinase inhibitors such as sorafenib. Suggested causes are direct effects on thyroid tissue and increased extrathyroidal metabolism of serum thyroxine and 3,5,3-triiodothyronine. We postulated that tyrosine kinase inhibitors may affect the peripheral metabolism of TSH as well. The effect of sorafenib on TSH cleara...

The pathogenesis of Graves' orbitopathy (GO) remains unknown. The hypothesis of a causal relationship between autoimmunity against the TSH receptor (TSHR) and GO is supported by clinical studies. Radioiodine treatment is associated with worsening or new onset of GO, possibly via antigen shedding or by inducing hypothyroidism. The coexistence of thyroid cancer with Graves' disease (GD) and GO is...

introduction: recombinant human thyroid-stimulating hormone(rhtsh) increases radioactive iodine uptake(raiu) in selected populations, while lithium is used as an adjunct to radioactive iodine (rai) therapy in graves’ disease with low raiu. in this report, both drugs used in combination, overcame low iodine-131 uptake in a graves’ patient. clinical case: a 39-year old female with graves’ disease...

Objective To compare the short- and long-term outcomes of adjuvant therapy with radioactive iodine (RAI) preceded by the administration of recombinant human TSH (rhTSH) versus thyroid hormone withdrawal (THW) in patients with papillary thyroid carcinoma and clinically apparent lymph node metastases not limited to the central neck compartment (cN1b). Subjects and methods The sample consisted o...

We report on a high-dose radioiodine therapy after injection of recombinant human thyrotropin (rhTSH) in a 61-y-old woman with compression of the spinal cord caused by metastasis of a follicular thyroid carcinoma. Fourteen years ago, the patient underwent subtotal thyroidectomy because of multinodular goiter without any histologic evidence for malignant disease, and the patient was put on thyro...

The purpose of this study was to identify the factors that predict incomplete low-dose radioiodine remnant ablation (RRA) with recombinant human thyroid-stimulating hormone (rhTSH) and to report the adverse events associated with this treatment. Between 2012 and 2014, 43 consecutive patients with thyroid cancer received low-dose RRA with rhTSH after total thyroidectomy. We retrospectively inves...

Recombinant human thyroid-stimulating hormone (rhTSH) enhances 131I uptake, permitting a decrease in radiation for the treatment of multinodular goiter (MNG). Our objective was to evaluate the safety and efficacy of a single 0.1-mg dose of rhTSH, followed by 30 mCi 131I, in patients with MNG. Seventeen patients (15 females, 59.0 +/- 13.1 years), who had never been submitted to 131I therapy, rec...
