OBJECTIVE The prognostic values of serum thyroglobulin (Tg) and antithyroglobulin antibody (TgAb) levels, measured immediately before I-131remnant ablation in patients with differentiated thyroid cancer (DTC), have been advocated by some researchers; however, it had controversial outcomes. This study was carried out to examine this dilemma and to check the clinical significance of basal serum T...

AIMS To investigate the natural history and incidence of autoimmune thyroiditis (AIT) in paediatric patients with type 1 diabetes (T1D). METHODS Since 1990, annual screening for thyroid disease has been performed in children and adolescents with T1D. Antibodies against thyroperoxidase (anti-TPO) and thyroglobulin (anti-TG) as well as TSH were measured in 659 patients (54.3% boys). In 126 pati...

AIM In our study, we investigated the levels of glutamic acid decarboxylase antibody (anti-GAD), islet cell antibody (ICA), thyroperoxidase antibody (anti-TPO), thyroglobulin antibody (anti-TG), antinuclear antibodies (FANA), antibodies to double-stranded DNA (anti-ds DNA), antibody to Sjögren syndrome A antigen (anti-SSA), antibody to Sjögren syndrome B antigen (anti-SSB), Smith antibody (anti...

OBJECTIVE To investigate thyroid autoimmunity in a very large nationwide cohort of children and adolescents with type 1 diabetes. RESEARCH DESIGN AND METHODS Data were analyzed from 17,749 patients with type 1 diabetes aged 0.1-20 years who were treated in 118 pediatric diabetes centers in Germany and Austria. Antibodies to thyroglobulin (anti-TG) and thyroperoxidase (anti-TPO) were measured ...

OBJECTIVE To evaluate the postoperative complications and to evaluate and stratify thyroglobulin (Tg) response associated with revision surgery for thyroid malignancy. STUDY DESIGN Case series with chart review. SETTINGS Academic, tertiary care center. SUBJECTS AND METHODS All patients with regionally recurrent thyroid carcinoma and who underwent revision thyroid surgery by the senior aut...

In patients with papillary thyroid carcinoma (PTC), detectable serum thyroglobulin (Tg) after total thyroidectomy implies biochemically persistent disease (BPD). We reported that the thyroglobulin-doubling time (Tg-DT) was a potent prognostic indicator in patients with BPD. To identify factors that are related to BPD and Tg-DT, we performed new analyses on the data gathered in our previous stud...

CONTEXT Thyroglobulin (TG) gene mutations cause congenital hypothyroidism (CH) with goiter. A founder effect has been proposed for some frequent mutations. Mutated proteins have a defect in intracellular transport causing intracellular retention with ultrastructural changes that resemble an endoplasmic reticulum storage disease. OBJECTIVE To reveal new aspects of thyroglobulin pathophysiology...

Serum thyroglobulin measurement by immunoassay is used to detect residual or recurrent thyroid cancer after thyroid ablation. However, the usefulness of immunoassay is limited by both the requirement for thyroid hormone withdrawal to attain optimal test sensitivity and interference by antithyroglobulin antibodies. To circumvent these problems, we amplified thyroglobulin messenger ribonucleic ac...

BACKGROUND During the detection of neck recurrence in patients with Papillary Thyroid Carcinoma (PTC), sometimes it is difficult to distinguish metastatic from inflammatory neck lymph nodes. The measurement of serum thyroglobulin (sTg) under thyroid hormone suppression therapy the presence of serum thyroglobulin antibodies (sAbTg), the diagnostic whole body scan and cytology can give false nega...
