Summary Aim of this study is to evaluate new and controversially discussed indications for determining the thyroglobulin (Tg) level in different thyroid diseases to support routine diagnostics. Methods: The following groups were included: 250 healthy subjects without goiter, 50 persons with diffuse goiter, 161 patients with multinodular goiter devoid of functional disorder (108 of them underwent surgery, in 17 cases carcinomas were detected), 60 hyperthyroid patients with autonomously functioning nodular goiter, 150 patients with Hashimoto’s thyroiditis and 30 hyperthyroid patients with Graves’ disease. Results: The upper limit of the normal range of the Tg level was calculated as 30 ng Tg/ml. The evaluation of the collective with diffuse goiter showed that the figure of the Tg level can be expected in a similar magnitude as the thyroid volume in milliliters. Nodular tissue led to far higher Tg values then presumed when considering the respective thyroid volume, with a rather high variance. A formula for a rough prediction of the Tg levels in nodular goiters is described. In ten out of 17 cases with thyroid carcinoma, the Tg was lower than estimated with thyroid and nodular volumes, but two patients showed a Tg exceeding 1000 ng/ml. The collective with functional autonomy had a significantly higher average Tg level than a matched euthyroid group being under suppressive levothyroxine substitution. However, due to the high variance of the Tg values, the autonomy could not consistently be predicted with the Tg level in individual cases. The patients with Hashimoto’s thyroiditis showed slightly decreased Tg levels. In Graves’ disease, a significantly higher average Tg level was observed compared with a matched group with diffuse goiter, but 47% of all Tg values were still in the normal range (< 30 ng/ml). Conclusion: Elevated Tg levels indicate a high probability of thyroid diseases, such as malignancy, autonomy or Graves’ disease. However, as low Tg concentrations cannot exclude the respective disorder, a routine Tg determination seems not to be justified in benign thyroid diseases.

Se Status

Selenium (Se) deficiency has been implicated in the pathogenesis of Hashimoto’s thyroiditis (HT), although the available evidence is limited. The present study aimed to explore the interrelationships between serum Se status with measures of thyroid function and antioxidant defense in new cases of HT patients with hypoechogenic thyroid. HT patients (n = 49) and matched controls (n = 50) were recruited. Selenium, thyroid hormone panel, thyroid volume (TVol), glutathione (GSH), glutathione peroxidase3 (GPx3) activity, urinary iodine concentration (UIC), and urinary creatinine (Cr) were assessed. HT patients exhibited lower Se levels compared to controls (p < 0.001) with the rates of Se-deficient (<0.85 µmol/L) participants being 58.8% and 34%, respectively. Se-deficient patients exhibited higher thyroid stimulating hormone (TSH), Thyroid volume (TVol), thyroglobulin, antibody-titers, GPx3 activity and UIC/Cr compared to Se-sufficient patients (all p < 0.001). In the Se-deficient patients, inverse correlations were seen between Se-levels with TSH, TVol, and Thyroid peroxidase antibody (TPO-Ab) (all p < 0.001). This study is the first to uncover that coexisting Se-deficiency and elevated iodine in HT may enhance autoimmune reactions and accelerate the deterioration of thyroid function through oxidative stress. Our study also highlights the importance of optimal Se status in this disease, thus providing a rationale for the execution of intervention trials for the evaluation of the clinical benefits of antioxidant-status improvement in HT.

Aim. The aim of the study was to compare the expression of sodium iodide symporter (NIS), thyroglobulin (Tg), tumor necrosis factor-α(TNFα), and interleukin-1βgenes in patients with Hashimoto’s thyroiditis (HT) and healthy individuals.Subjects and Methods.Thyroid cells were obtained from 39 patients with HT and 15 controls by an ultrasound guided fine needle aspiration biopsy.Results. The patients with HT had lower Tg and NIS mRNA (P=0.002andP=0.001, resp.), as well as higher TNFαmRNA expression (P=0.049) than the controls. In the HT group Tg mRNA expression correlated positively with NIS mRNA expression (R=0.739,P=0.0001) and thyroid volume (R=0.465,P=0.0005), as well as negatively with TNFαmRNA expression (R=-0.490,P=0.001) and anti-peroxidase antibodies (TPOAb) level (R=-0.482,P=0.0002), whereas NIS mRNA expression correlated positively with thyroid volume (R=0.319,P=0.02), as well as negatively with TNFαmRNA expression (R=-0.529,P=0.0006) and TPOAb level (R=-0.422,P=0.001).Conclusions.Our results suggest that decreased Tg and NIS expression in thyroid cells may result in reduced active iodide transport and reduced thyroid volume in patients with HT.

OBJECTIVE: Several studies have suggested that iodine may influence thyroid hormone status, and perhaps antibody production, in patients with autoimmune thyroid disease. To date, studies have been carried out using large amounts of iodine. Therefore, we evaluated the effect of small doses of iodine on thyroid function and thyroid antibody levels in euthyroid patients with Hashimoto's thyroiditis who were living in an area of mild dietary iodine deficiency. METHODS: Forty patients who tested positive for anti-thyroid (TPO) antibodies or with a moderate to severe hypoechogenic pattern on ultrasound received 250 microg potassium iodide daily for 4 months (range 2-13 months). An additional 43 patients positive for TPO antibodies or with hypoechogenicity on ultrasound served as a control group. All patients were TBII negative. RESULTS: Seven patients in the iodine-treated group developed subclinical hypothyroidism and one patient became hypothyroid. Three of the seven who were subclinically hypothyroid became euthyroid again when iodine treatment was stopped. One patient developed hyperthyroidism with a concomitant increase in TBII titre to 17 U/l, but after iodine withdrawal this patient became euthyroid again. Only one patient in the control group developed subclinical hypothyroidism during the same time period. All nine patients who developed thyroid dysfunction had reduced echogenicity on ultrasound. Four of the eight patients who developed subclinical hypothyroidism had TSH concentrations greater than 3 mU/l. In 32 patients in the iodine-treated group and 42 in the control group, no significant changes in thyroid function, antibody titres or thyroid volume were observed. CONCLUSIONS: Small amounts of supplementary iodine (250 microg) cause slight but significant changes in thyroid hormone function in predisposed individuals.

Abstract Background The purpose of this study was to determine the association of sonographic parameters with the serum levels of anti-thyroid peroxidase (TPO), anti-thyroglobulin (Tg), and thyroid hormones in patients with Hashimoto's thyroiditis. Methods 149 patients (118 females, 31 males; aged 18–60 years; mean age: 38.60 ± 8.03 years) who were diagnosed with Hashimoto's thyroiditis were enrolled in the study. Blood sample was taken to measure the serum levels of free T3 and T4, thyroid stimulating hormone (TSH), anti-TPO antibody titers, and anti-Tg antibody titers. The thyroid sonography of each patient was classified into one of the five grades by real-time ultrasonography (US) based on echogenicity, thyroid size, and thyroid pattern. We evaluated whether a correlation existed between thyroid characteristics on US and serum levels of thyroid hormones, anti-TPO and anti-Tg. Results Nodular structures were detected in 54 (36.2%) patients (38 micronodular and 16 macros nodular). Echogenicity was recorded as isoechoic in 15 (10.07%) and hypoechoic in 119 (79.87%) subjects. Euthyroid ‎subjects had significantly thicker isthmus than overt and subclinical hypothyroid patients (p = 0.018). Mean serum TSH, anti-Tg and anti-TPO titers was significantly higher in patients with micronodules than those with micronodules and subjects without nodules (P < 0.05). Isthmus thickness had a significant negative correlation with FT4 and FT3 (P = 0.046; r = 0.11& P = 0.017; r = 0.15, respectively). Thyroid autoantibodies had positive significant correlations with different parameters of the thyroid volume (P < 0.05). Conclusions Thyroid’s US findings in addition to serum levels of anti-Tg and anti-TPO titers would be useful in diagnosis and evaluation of the severity and extent of Hashimoto's thyroiditis, but further evaluations are needed.

ABSTRACT Hashimoto's thyroiditis (HT) is the commonest cause of hypothyroidism, especially in iodine replete areas. The clinical presentation of HT is usually insidious with mild goiter and progressive hypothyroidism. But, HT presents with large goiter and compressive symptoms in some cases. The treatment of HT is mostly conservative with thyroxine treatment sooner or later. Occasionally, surgery is indicated for large goiters with persistent pressure symptoms or associated nodules. We report a rare case of unusually large goiter with compressive symptoms, hitherto unreported in literature. How to cite this article Bhargav PRK, Amar V, Uday SK.
