Background: Hyperthyroidism is a common systemic disorder where Graves’ disease is known as the leading cause of the disease. Thyroid stimulating hormone, T4 and T3 antibody assay are usually performed for the diagnosis of the pathology. However, with uncertainty in the results and in order to estimate the magnitude and the exact cause of the disease, radioactive iodine uptake (RAIU) test is recommended. The aim of this study is to evaluate underlying pathology in the patients presenting hyperthyroidism using RAIU test results. Methods: This is a cross-sectional retrospective study conducted on the patients with hyperthyroidism referred to Shahid Madani Hospital in Khorramabad. Data regarding the biochemical analysis and RAIU test was collected from the records and a questionnaire based on demographic and clinical information was completed for each patient. Results: Of 137 patients presenting hyperthyroidism, 62.04% were presented with Graves’ disease, 24.08% with toxic multinodular goiter and 13.86% with toxic adenoma. 24-hour RAIU test showed that the percent of radioiodine uptake was most in toxic adenoma 67.7%, Graves’ disease 53.5% and multinodular goiter 39%, respectively. From the age-based analysis, we found that Graves’ was most common in 20-30 years old individuals 34%, multinodular goiter in 50+ aged individuals 36.3% and toxic adenoma was most prevalent in 30-40 and 50+ aged patients, 26.3% each. In our population of interest, 81.8% toxic multinodular goiter patients were females. Conclusions: Our study presents the outcome of RAIU tests in hyperthyroidism based on the underlying pathologies. We also conclude, in light of other findings, Graves’ disease is the most common cause of hyperthyroidism in our population.

Abstract INTRODUCTION The diagnosis of Graves′disease (GD) is likely when patient presents hyperthyroidism, symmetrical goiter and orbitopathy and further evaluation is unnecessary. Nevertheless patient with nodular thyroid or in the absence of clinical orbitopathy, measurement of TSH receptor antibodies (TRAb) is recommended to distinguish GD from toxic multinodular goiter, toxic adenoma and other etiologies. Radioiodine uptake (RAIU) also helps to diagnosis when TRAb is unavailable. Third generation TRAb assays measure all types of TSH receptor antibodies: stimulating, blocking and neutral with an excellent sensitivity and specificity for GD diagnosis. Recently, an automated bioassay for the thyroid stimulating immunoglobulin (TSI) was introduced to improve GD diagnosis. OBJECTIVE To analyze clinical performance of TSI and compare with TRAb assay for GD diagnosis. MATERIAL AND METHODS Serum samples of 117 patients with thyrotoxicosis due to GD, toxic multinodular goiter and toxic adenoma were runned simultaneously in two analytical system commercially available. TRAb was analyzed by Elecsys Anti-TSHR assay (Roche Diagnostics, Germany) in a Cobase411 analyzer (Roche Diagnostics, Germany) and results, according to the manufacturer interval reference, were negative if < 1.75 IU/L (analytical range: 0.3 to 40 IU/L). TSI was measured by Immulite TSI assay (Siemens Healthcare, UK) in Immulite XPi 2000 and results, according to the manufacturer interval reference, were negative if < 0.55 IU/L (analytical range: 0.1 to 40 IU/L). Clinical diagnoses of thyrotoxicosis were determined according to ATA guideline (2016). Statistical analyses were performed using SPSS and MedCalc softwares. Comparison were evaluated by regression equations and were considered significant when p values were < .05. RESULTS From 2017 to 2019 a total of 312 serum samples from 117 patients (96 females) were evaluated with mean age 49.5 ±15.8 years-old (18 to 90 yrs). We excluded 26 results above the analytical measurement range of both assays. A high degree correlation was observed with a slope of 0.647 and an intercept -.094 IU/L. Spearman correlation coefficient was 0.858 (p < 0.0001, 95% CI 0.825 to 0.886). TSI assay had higher sensibility and negative predictive value compared to TRAb (95.6% vs 88.5% and 83.6% vs 54.8%, respectively) but lower specificity and positive predictive value (90.3% vs 100% and 97.5% vs 100%, respectively). The results of TSI assay showed good agreement with those of the TRAb assay (k=0.74). A total of 31 samples were discordant, favoring to TSI assay in all but one case of GD according to clinical diagnosis (TRAb positive and TSI negative). CONCLUSION TSI assay showed an excellent performance for GD diagnosis with a better sensibility than TRAb assay.

ABSTRACT Background and objective Malignant tumors of the thyroid gland are the most common of the endocrine malignancies. Although, patients with thyroid cancer have high 5 years survival rate, thyroid cancer is the most seen cause of mortality among cancers of the endocrine organs. The incidence of thyroid cancer in hyperthyroid patients varies from 0.1 to 21% in the literature. We aimed in this study to analyze the frequency of coexisting thyroid cancer and hyperthyroidism in our experience. Results Total 230 patients, who were operated for hyperthyroidism without the suspicion of thyroid malignancy between January 2005 and September 2010 were included in our study. Toxic multinodular goiter, toxic adenoma and Graves’ disease were diagnosed preoperatively in 187, 16 and 27 patients respectively. Histopathological thyroid malignancy was detected in 13 patients (5.7%). Conclusion Thyroid cancer with variable incidence up to 21% should be remembered in differential diagnosis of hyperthyroid patients. How to cite this article Tastan B, Dogu A, Sevim Y.

Graves’ Disease (GD) is the most common etiology of thyrotoxicosis, followed by toxic multinodular goiter and toxic adenoma. GD can be managed with anti-thyroid drugs (ATDs), surgery, or radioactive iodine (RAI). Thyroid-associated orbitopathy (TAO) or Graves’ Ophthalmopathy (GO) affects 25%-50% patients with GD, and its presence usually dissuade clinicians to use RAI in treating hyperthyroidism. The presence of GO is a relative contraindication use of RAI in patients with GD, as RAI can worsen existing GO. Corticosteroid prophylaxis can be given to such patients to reduce likelihood of worsening of GO. However, patient with moderate to severe active GO is currently advised against undergoing RAI. Established guidelines recommend the use of corticosteroid prophylaxis in these patients. We reported a patients with GD and orbitopathy who was treated with RAI and was given steroid prophylaxis to prevent worsening of GO.

Radioiodine therapy for benign and malignant thyroid diseases was introduced about 70 years ago, however, there is still a lack of consensus regarding indications, doses and procedure. This review covers treatment results in immunogenic hyperthyroidism including the problem of orbitopathy. Radioiodine therapy for toxic and non-toxic multinodular goiter is also discussed with striking possibility of enhanching the radioiodine uptake. In this respect the recombinant human thyrotropin should be mentioned. Thyroid cancer treatment protocol has changed, too, due to ineffectivity in low-risk patients. More attention is needed to the carcinogenecity of radioiodine. The numerous problems mentioned above require large and well-designed prospective trials to resolve the fundamental questions. The author emphasizes that radioiodine dose should be administered in doses as low as reasonably achievable. Orv. Hetil., 2016, 157(3), 83–88.

Abstract Background: Most thyroid nodules are benign and do not need intervention. Toxic adenoma and toxic multinodular goiter (MNG) are common causes of hyperthyroidism, second in prevalence only to Graves’ disease. Toxic adenoma and MNG are the result of focal or diffuse hyperplasia of thyroid follicular cells whose functional capacity is independent from regulation by the thyroid stimulating hormone (TSH). When conservative treatment modalities fail to ensure an euthyroid state, surgical intervention is required, typically surgical left or right thyroid lobectomy. Radiofrequency ablation (RFA) is a new percutaneous treatment option that results in thermal tissue necrosis and fibrosis. As a result of this process, the thyroid nodules shrink. Case presentation: We describe a case of a young woman with a large toxic thyroid adenoma who refused surgery. She was admitted to a one-day surgery unit and underwent radiofrequency ablation under total intravenous anesthesia. Using “moving shot technique” the procedure went uneventfully and the toxic adenoma displayed a significant volume reduction with resolution of the hyperthyroid symptoms. The patient also reported a significant improvement of her neck symptoms (from 7/10 to 1/10 on a Visual Analogue Scale). Conclusions: Radiofrequency ablation is a new, well tolerated, safe and effective treatment option in selected patients with benign thyroid nodules, toxic adenomas of the thyroid gland and multinodular goiter. To the best of our knowledge, this is the first time such treatment modality is used in Bulgaria.

Hyperthyroidism is a clinical state that results from abnormally elevated thyroid hormones. Thyroid gland affects many organ systems; therefore, patients usually present with multiple clinical manifestations that involve many organ systems such as the nervous, cardiovascular, muscular, and endocrine system as well as skin manifestations. Hyperthyroidism is most commonly caused by Graves disease, which is caused by autoantibodies to the thyrotropin receptor (TRAb). Other causes of hyperthyroidism include toxic multinodular goiter, toxic single adenoma, and thyroiditis. Diagnosis of hyperthyroidism can be established by measurement of thyroid-stimulating hormone (TSH), which will be suppressed with either elevated free T4 and/or T3 (overt hyperthyroidism) or normal free T3 and T4 (subclinical hyperthyroidism). Hyperthyroidism can be treated with antithyroid drugs (ATDs), radioactive iodine (RAI), or thyroidectomy. ATDs have a higher replacement rate when compared with RAI or thyroidectomy. Recent evidence has shown that thyroidectomy is a very effective, safe treatment modality for hyperthyroidism and can be performed as an outpatient procedure. This review article provides some of the most recent evidence on diagnosing and treating patients with hyperthyroidism.
