Hashimoto's thyroiditis is a common auto-immune disorder. The most common presenting symptoms may include anxiety, negative mood, depression, dry skin, cold intolerance, puffy eyes, muscle cramps and fatigue, deep voice, constipation, slow thinking and poor memory. Clinical manifestations of the disease are defined primarily by low levels of thyroid hormones; therefore it is treated by hormone replacement therapy, which usually consists of levothyroxine (LT4). Selenium might reduce antibody levels and result in a decreased dosage of LT4 and may provide other beneficial effects (e.g. on mood and health-related quality of life). To assess the effects of selenium supplementation on Hashimoto's thyroiditis. We searched the following databases up to 2 October 2012: CENTRAL in The Cochrane Library (2012, Issue 10), MEDLINE, EMBASE, and Web of Science; we also screened reference lists of included studies and searched several online trial registries for ongoing trials (5 November 2012). Randomised controlled clinical trials that assessed the effects of selenium supplementation for adults diagnosed with Hashimoto's thyroiditis. Study selection, data extraction, assessment of risk of bias, and analyses were carried out by two independent review authors. We assessed the quality of the evidence of included studies using GRADE. We were unable to conduct a meta-analysis because clinical heterogeneity between interventions that were investigated is substantial. Four studies at unclear to high risk of bias comprising 463 participants were included. The mean study duration was 7.5 months (range 3 to 18 months). One of our primary outcomes－'change from baseline in health related quality of life'－and two of our secondary outcomes－'change from baseline in LT4 replacement dosage at end of the study' and 'economic costs'－were not assessed in any of the studies. One study at high risk of bias showed statistically significant improvement in subjective well-being with sodium

This review of literature attempts to identify the factors that are involved in the pathogenesis of Hashimoto thyroiditis, an immune defect in an individual with genetic susceptibility accompanied with environmental factors. The frequency of Hashimoto's disease is a growing trend and among Caucasians it is estimated at approximately 5%. The dysfunction of the gland may be clinically evident (0.1–2% of the population) or subclinical (10–15%). The pathology is diagnosed five to ten times more often in women than men and its incidence increases with the age (the peak of the number of cases is between 45 and 65); however, it can also be diagnosed in children. The pathogenesis of Hashimoto's thyroiditis is still not fully comprehended. In the etiology of Hashimoto thyroiditis excessively stimulated T CD4+ cells are known to play the most important role. Recent research has demonstrated an increasing role of newly discovered cells such as Th17 (CD4+IL-17+) or T regulatory cells (CD4+CD25+highFoxP3+) in the induction of autoimmune disorders. The process of programmed cell death also plays an equally important role in the pathogenesis and the development of hypothyroidism. PMID:26000316

The objective of this study was to investigate and evaluate the prevalence of incidental thyroid diffuse and diffuse-plus-focal fluorine-18 fluorodeoxyglucose (FDG) uptake in healthy subjects who underwent cancer screening on positron emission tomography (PET) scan, and also to evaluate the prevalence of thyroid cancer and Hashimoto's thyroiditis. We carried out a retrospective review of 1626 subjects who underwent PET scanning at our institution. Diffuse uptake was defined as FDG uptake in the whole thyroid gland, whereas diffuse-plus-focal uptake was defined as a thyroid lesion with both diffuse uptake and focal FDG uptake. The maximum standardized uptake value of the thyroid lesions was recorded and reviewed. In each selected subject with positive thyroid FDG uptake, serum thyroid-stimulating hormone, thyroid hormone, and thyroid antibodies were measured. Fine needle aspiration cytology was performed on patients with a definite nodule using ultrasonography. Twenty-nine subjects (1.78%) were identified as having either diffuse FDG uptake (n=25, 1.53%) or diffuse-plus-focal FDG uptake (n=4, 0.24%). All subjects with diffuse FDG uptake were diagnosed as having Hashimoto's thyroiditis. In 1 of the 25 subjects with diffuse FDG uptake and two of the four with diffuse-plus-focal FDG uptake, histopathologic diagnosis showed papillary thyroid carcinoma associated with Hashimoto's thyroiditis. However, PET scan did not detect papillary carcinoma associated with Hashimoto's thyroiditis in one of the three subjects. Our results suggest that although diffuse FDG uptake usually indicates Hashimoto's thyroiditis, the risk of thyroid cancer must be recognized in both diffuse FDG uptake and diffuse-plus-focal FDG uptake on PET scan.

The purpose of this article is to compare sonographic features of benign and malignant nodules in patients with diffuse Hashimoto thyroiditis. As part of an ongoing multiinstitutional study, patients who underwent ultrasound and fine-needle aspiration of one or more thyroid nodules were analyzed for a variety of predetermined sonographic features. Patients with a sonographic appearance consistent with diffuse Hashimoto thyroiditis and with coexisting nodules that could be confirmed to be benign or malignant by fine-needle aspiration or surgical pathologic analysis were included in the study. Among nodules within diffuse Hashimoto thyroiditis, 84% (69/82) were benign (35 nodular Hashimoto thyroiditis, 32 nodular hyperplasia, and two follicular adenoma), and 16% (13/82) were malignant (12 papillary carcinoma and one lymphoma). Malignant nodules were more likely to be solid and hypoechoic (62% vs 19%). All types of calcifications were more prevalent among malignant nodules, including microcalcifications (39% vs 0%), nonspecific tiny bright reflectors (39% vs 6%), macrocalcifications (15% vs 3%), and eggshell (15% vs 2%). Benign nodules were more likely to be hyperechoic (46% vs 9%), to have a halo (39% vs 15%), and to lack calcifications (88% vs 23%). Benign nodules more often had ill-defined margins (36% vs 8%). Sonographic features of benign and malignant nodules within diffuse Hashimoto thyroiditis are generally similar to the features typical of benign and malignant nodules in the general population. If calcifications of any type are added to the list of malignant sonographic features, the decision to biopsy a nodule in patients with diffuse Hashimoto thyroiditis can be based on recommendations that have been published previously.

Polymorphisms of the receptor for advanced glycation end products (RAGE) gene have been studied in various autoimmune disorders, but not in Hashimoto's thyroiditis. Also, increased oxidative stress has been described in patients with Hashimoto's thyroiditis. The aim of this study was to investigate the possible role of two common RAGE polymorphisms (-429T>C, -374T>A) in Hashimoto's thyroiditis; in parallel, we studied oxidative stress levels. A total of 300 consecutive euthyroid women were examined and classified into three groups: Hashimoto's thyroiditis with treatment (n = 96), Hashimoto's thyroiditis without treatment (n = 109) and controls (n = 95). For a rough evaluation of oxidative stress, total lipid peroxide levels in serum were measured. The -429T>C AluI and -374T>A MfeI polymorphisms of RAGE were studied in genomic DNA. Significant association of the RAGE system with Hashimoto's thyroiditis was found only with regard to the prevalence of the -429T>C, but not with -374T>A polymorphism. The levels of oxidative stress were significantly elevated in Hashimoto's thyroiditis patients under treatment. Further analysis demonstrated that an oxidative stress cut-off value of 590 μmol/L is associated with an increased risk of progression of Hashimoto's thyroiditis from euthyroidism to hypothyroidism; this risk is further increased in carriers of the RAGE -429T>C polymorphism. Our findings indicate that both examined risk factors may be implicated in the occurrence of Hashimoto's thyroiditis, but this covers only a fraction of the pathophysiology of the disease. © 2017 Stichting European Society for Clinical Investigation Journal Foundation.

Graves' disease and Hashimoto's thyroiditis are the most common causes of hyper and hypothyroidism, respectively. Differentiation of these 2 diseases, if the patient is euthyroid, may sometimes be extremely difficult on the basis of clinical and laboratory findings. The purpose of this study was to determine the sensitivity and specificity of gray scale sonography in differentiation of Graves' disease from Hashimoto's thyroiditis. This study included 149 patients divided into three groups, patients with Graves' disease (34 patients, mean age = 36.8 ± 10.17 years), Patients with Hashimoto's thyroiditis (62 patients, mean age = 33.4 ± 12.16 years) and control group (53 healthy people, mean age = 34.74 ± 16.87 years). Members of all groups were referred to a single radiologist for thyroid sonography for evaluation of thyroid echogenicity pattern. A total of 117 women and 32 men were examined by sonography. The most common sonographic pattern in Hashimoto and Graves' was homogenous hypo-echogenicity which was observed in 45.2% and 47.1% of cases, respectively. Peripheral hypo-echogenicity pattern was seen in 40.3% of Hashimoto's group with 100% specificity and 40.3% sensitivity. Central-hypoechogenic pattern was observed in 17.6% of Graves' group with 100% and 17.6% specificity and sensitivity, respectively. Our findings indicate that sonography has high specificity but low sensitivity in the diagnosis of either Graves' disease or Hashimoto's thyroiditis. It is therefore not possible to differentiate between these two diseases using sonography alone. Confirmation by laboratory data is also needed.

The aim of this study was to evaluate the usefulness of diffusion-weighted magnetic resonance imaging (DWMRI) for differentation between Graves' disease and Hashimoto's thyroiditis. Fifty patients (27 Graves diseases and 23 Hashimoto thyroiditis) and twenty healthy volunteers were examined using T1, T2 and DWMRI. The patients were diagnosed on the basis of physical findings and the results of thyroid function tests and serological tests. Circular ROIs were positioned on the bilateral thyroid lobes and isthmus. All measurements were repeated three different b values including 100, 600 and 1000 s/mm2 in all cases. ADC (Apparent diffusion coefficient) maps were calculated automatically with the MR system. Mean ADC values were 2.93 × 10-3, 1.97 × 10-3 and 1.62 × 10-3 mm2/s in the healthy volunteers; 3.47 × 10-3, 2.25 × 10-3 and 1.64 × 10-3 mm2/s in Graves' disease; 2.53 × 10-3, 1.76 × 10-3, 1.28 × 10-3 mm2/s in Hashimoto thyroiditis for b100, b600 and b1000, respectively. The ADC values of the Graves diseases were higher than healty volunteers and Hashimoto thyroiditis. ADC values were statistically significant for differentation between Hashimoto thyroiditis and Graves' disease all b values (p Hashimoto thyroiditis and Graves' disease.

Experience with 260 thyroidectomies at the North Carolina Memorial Hospital performed between 1875 and 1980 for a dominant thyroid mass was reviewed to determine the reliability of criteria for diagnosis and the indications for surgical treatment. Using the criteria of clinical findings, complemented by laboratory studies. Four patients had Hashimoto's thyroiditis coincidental to another disease for which thyroidectomy was performed. In seven patients Hashimoto's thyroiditis alone constituted the indications for operation. The indications for operation in these patients were: autonomous function with mild hyperthyroidism (2 patients); associated cold nodule (2 patients); thyromegaly unresponsive to suppressive therapy (2 patients); and rapidly enlarging mass simulating a neoplasm (1 patient). Only one of 71 patients with well differentiated carcinoma had Hashimoto's thyroiditis. One patient with Hashimoto's thyroiditis had associated lymphoma. In most patients, Hashimoto's thyroiditis can be identified using appropriate clinical and laboratory criteria without resorting to thyroidectomy to differentiate between thyroiditis and a neoplasm. Operations are indicated in patients with suspected or established chronic thyroiditis for: 1) the presence of a dominant mass with incomplete regression on suppressive therapy. 2) Progression of thyromegaly despite suppressive therapy. 3) Historic or physical findings suggest a malignancy. 4) Indeterminant findings on cutting needle biopsy.

The purpose of this study was to evaluate the potential relationship between Hashimoto's thyroiditis and BRAF(V600E) mutation status in patients with papillary thyroid carcinoma (PTC). A total of 619 patients with PTC who underwent total thyroidectomy with lymph node dissection were enrolled in this study. Univariable and multivariate analyses were used. Hashimoto's thyroiditis was present in 35.9% (222 of 619) of PTCs. Multivariate logistic regressions showed that BRAF(V600E) mutation, sex, extrathyroidal extension, and lymph node metastasis were independent factors for Hashimoto's thyroiditis. Female sex, more frequent extrathyroidal extension, and a higher incidence of lymph node metastasis were significantly associated with PTCs accompanied by BRAF(V600E) mutation without Hashimoto's thyroiditis compared with PTCs accompanied by BRAF(V600E) mutation with Hashimoto's thyroiditis. Hashimoto's thyroiditis was negatively associated with BRAF(V600E) mutation, extrathyroidal extension, and lymph node metastasis. In addition, Hashimoto's thyroiditis was related to less lymph node metastasis and extrathyroidal extension in PTCs with BRAF(V600E) mutation. Therefore, Hashimoto's thyroiditis is a potentially protective factor in PTC. © 2015 Wiley Periodicals, Inc. Head Neck 38: E1019-E1025, 2016. © 2015 Wiley Periodicals, Inc.

To determine whether the sonographic appearance of thyroid cancer differs in patients with and without Hashimoto thyroiditis. Patients with histologically proven thyroid cancer who had thyroid peroxidase (TPO) antibodies measured and sonography performed preoperatively were included. We evaluated each nodule for size, echogenicity, composition, margins, halo, and vascularity and evaluated the background heterogeneity of the gland. There were 162 thyroid cancers in 145 patients. Forty-two patients (29.0%) had Hashimoto thyroiditis with positive TPO antibodies, and 103 patients (71.0%) had negative TPO antibodies. The background echogenicity was more often heterogeneous in TPO antibody-positive patients compared to those who had negative TPO antibodies (57.1% versus 26.2%; P= .0005). Comparing cancers in TPO antibody-positive to TPO antibody-negative patients, there was no significant difference in the size, echogenicity, composition, margins, halo presence, calcification presence and type, or vascularity of the cancerous nodule (P > .05). Among TPO antibody-positive patients, comparing thyroid cancerous nodules in patients with heterogeneous glands to those with homogeneous glands, there was no significant difference in any sonographic characteristic except the margin of the nodule, which was more often irregular or poorly defined in heterogeneous glands and more often smooth in homogeneous glands (Pthyroid cancer are similar in patients with and without Hashimoto thyroiditis. Among patients with Hashimoto thyroiditis and thyroid cancer, the sonographic appearance of the cancerous nodule is similar, except that cancerous nodule margins are more likely to be irregular or poorly defined when the gland is heterogeneous. © 2015 by the American Institute of Ultrasound in Medicine.

Ataxia telangiectasia is a rare genetic disease characterized by neurological manifestations, infections, and cancers. In addition to these cardinal features, different autoimmune diseases can be seen in patients with ataxia telangiectasia. Although there were reports of positive autoimmune thyroid antibodies associated with ataxia telangiectasia, to our knowledge, we report the first cases of nodular Hashimoto thyroiditis in two patients with ataxia telangiectasia in the English medical literature. These cases illustrate that despite the rarity of nodular Hashimoto thyroiditis associated with ataxia telangiectasia, physicians should be aware of this possibility. Furthermore, thyroid examination of patient with ataxia telangiectasia is recommended for early diagnosis.

This report documents 3 pediatric papillary thyroid carcinoma cases with associated Hashimoto thyroiditis. In all 3 cases, hypoechoic nodules accompanied by multiple echogenic spots were noted on sonography of the thyroid. Hashimoto thyroiditis was suspected on the basis of positive thyroid autoantibody test results and pathologic examinations of thyroidectomy specimens, which revealed chronic thyroiditis with lymphocytic infiltration as the background of papillary thyroid carcinoma development. The potential for papillary carcinoma development warrants close follow-up, and meticulous sonographic examinations must be performed in children with Hashimoto thyroiditis. © 2014 by the American Institute of Ultrasound in Medicine.

Purpose: To evaluate color-Doppler features predictive of focal Hashimoto's thyroiditis. Materials and methods: A total of 521 patients with 561 thyroid nodules that underwent surgeries or gun biopsies were included in this study. These nodules were divided into three groups: focal Hashimoto's thyroiditis (104 nodules in 101 patients), benignity other than focal Hashimoto's thyroiditis (73 nodules in 70 patients), and malignancy (358 nodules in 350 patients). On color Doppler sonography, four vascularity types were determined as: hypovascularity, marked internal flow, marked peripheral flow and focal thyroid inferno. The χ 2 test was performed to seek the potential vascularity type with the predictive ability of certain thyroid pathology. Furthermore, the gray-scale features of each nodule were also studied. Results: The vascularity type I (hypovascularity) was more often seen in focal Hashimoto's thyroiditis than other benignity and malignancy (46% vs. 20.5% and 19%). While the type II (marked internal flow) showed the opposite tendency (26.9% [focal Hashimoto's thyroiditis] vs. 45.2% [other benignity] and 52.8% [malignancy]). However, type III (marked peripheral flow) was unable to predict any thyroid pathology. Importantly, type IV (focal thyroid inferno) was exclusive to focal Hashimoto's thyroiditis. All 8 type IV nodules appeared to be solid, hypoechoic, and well-defined. Using “focal thyroid inferno” as an indicator of FHT, the diagnostic sensitivity and specificity were 7.7% and 100% respectively. Conclusions: The vascularity type of “focal thyroid inferno” is specific for focal Hashimoto thyroiditis. Recognition of this particular feature may avoid unnecessary interventional procedures for some solid hypoechoic thyroid nodules suspicious of malignancy.

Color Doppler ultrasonographic(US) features of 28 patients with Hashimato's thyroiditis were evaluated with regard to echo and color-flow patterns. Correlation of color-flow pattern with thyroid function was performed. All 28 patients showed varying degrees of diffuse enlargement of the thyroid gland and a heterogeneous echo pattern.Color-flow pattern of increased blood flow. Low to moderate, focally increased blood flow was seen in 26 patients(92.8%). Of these 26 patients, 24 patients showed subclinical hypothyroidism or euthyroidism. Two patients who showed hyperthyroidism showed several pieces of focally increased color flow, Which was noted during both systole and diastole. Diffuse, multifocal color-flow throughout thyroid gland was seen in two patients with Hashimato's thyroiditis: one with clinical hypothyroidism and the other with subclinical hypothyroidism. Even though Hashimoto's thyroiditis showed variable color-flow patterns, we believe that heterogenous parenchymal echopattern with low or moderately increased flow is a rather characteristic feature of Hashimoto's thyroiditis, and we suggest that color Doppler US provides additional information for evaluation of Hashimoto's thyroiditis

Noonan syndrome is an autosomal dominant, multisystem disorder. Autoimmune thyroiditis with hypothyroidism is an infrequent feature in patients with Noonan syndrome. A 16-year-old boy was admitted because of chest discomfort and dyspnea; an echocardiogram revealed pericardial effusion. Additional investigations led to a diagnosis of severe hypothyroidism due to Hashimoto thyroiditis. The patient was treated with L-thyroxine at 0.15 mg daily. However, during admission, he developed symptoms of cardiac tamponade. Closed pericardiostomy was performed, after which the patient's chest discomfort improved, and his vital signs stabilized. Herein, we report a case of an adolescent with Noonan syndrome, who was diagnosed with Hashimoto thyroiditis with an unusual presentation of cardiac tamponade.

To demonstrate sonographic features of Hashimoto's thyroiditis according to the thyroid function. We reviewed 54 thyroid ultrasonographic examinations of untreated Hashimoto's thyroiditis. We reviewed thyroid ultrasonographic examinations and focused on the presence of ill-defined low echoic lesions and glandular enlargement. We performed another thyroid ultrasonographic examination of 14 healthy volunteers, in order to obtain normal size of thyroid gland. Comparison was made between these morphologic characteristics and functional stage of the disease. The mean diameter of thyroid gland was 2.16 ± 0.43 cm in patients with Hashimoto's thyroiditis, and 1.41 ± 0.42 cm in normal control group of the thyroid gland. There was no statistically significant relationship between thyroid function and size. There was morphologic abnormalities in 46 patients (85%). Among them, 7 patients revealed diffuse low echogenicity in the entire thyroid gland, 32 patients showed peripherally located, ill-defined focal hypoechoic lesion, and 7 patients showed solitary or multiple. well-defined nodular lesions. Decreased echogenicity of the thyroid gland was related to hypothyroid status. Hashimoto's thyroiditis has specific morphologue characteristics in ultrasonographic features, which are well correlated with thyroid function.

To compare the diagnostic accuracy of ultrasonography (US), F18-fluorodeoxyglucose positron emission tomography/CT (PET/CT), contrast enhanced CT (CECT), serum anti-thyroid antibody for detecting Hashimoto's thyroiditis in thyroid cancer patients who underwent neck surgery. A total of 150 patients with suspicious for thyroid cancer, who had previously undergone US guided needle aspiration of thyroid, were evaluated with the use of US, PET/CT, CECT and serum anti-thyroid antibody. The four studies were performed within two months before neck surgery. Hashimoto's thyroiditis was confirmed by histopathological results. The diagnostic accuracy of US, PET/CT, CECT and serum anti-thyroid antibody were calculated statistically. Hashimoto's thyroiditis was diagnosed in 51 out of the 150 patients, following neck surgery. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of US were 76.5%, 92.9%, 84.8%, 88.5%, and 87.3%, respectively. The corresponding values of PET/CT were 37.3%, 96.0%, 82.6%, 74.8%, and 76.0%, and CECT were 62.7%, 89.9%, 76.2%, 82.4%, and 80.7%, and serum anti-thyroid antibody level were 90.2%, 93.9%, 88.5%, 94.9%, and 92.7%, respectively. McNemar test revealed significant difference among PET/CT and others, but no significant differences among US, CECT and serum anti-thyroid antibody. Overall, serum anti-thyroid antibody showed most accurate diagnostic performance. In detecting Hashimoto's thyroiditis, serum anti-thyroid antibody showed higher diagnostic accuracy than others. US also showed relatively high diagnostic accuracy.

Hypoparathyroidism is an uncommon disease and its coexistence with chronic renal failure is quite rare. Hypocalcemia and hyperphosphatemia are seen in both diseases. Diagnosis of hypoparathyroidism may be overlooked when parathormone response is not evaluated in patients with chronic renal failure. A 19-year-old female patient who had been receiving hemodialysis for 3 years because of chronic renal failure was diagnosed as idiopathic hypoparathyroidism and hashimoto thyroiditis. When her medical records on the first admission and medical history were evaluated, hypoparathyroidism and hashimoto thyroiditis were seen to be present also when she was started hemodialysis. Idiopathic hypoparathyroidism should be suspected in case as absence of parathormone response to hypocalcemia in patients with chronic renal failure. It should be taken into consideration that hashimoto thyroiditis may accompany and required analysis should be done.

Low triiodothyronine syndrome is a physiological adaptation encountered in anorexia nervosa (AN) and generally improves with sufficient weight gain. However, when a primary thyroid pathology accompanies AN, both the evaluation of thyroid hormone levels and the management of the co-morbid disease become more challenging. Hashimoto thyroiditis could complicate the management of AN by causing hyper- or hypothyroidism. AN could also negatively affect the treatment of Hashimoto thyroiditis by altering body weight and metabolic rate, as well as by causing drug non-compliance. We present the case of a 15-year-old boy with comorbid AN restrictive sub-type and Hashimoto thyroiditis. In this case report, we aimed to draw attention to the challenges that could be encountered in the diagnosis, treatment, and follow-up of patients with AN when accompanied by Hashimoto thyroiditis.

A case of parasitic thyroid nodule is presented. The patient was a non symptomatic 53-year-old white woman, on irregular course of L-thyroxine to treat hypothyroidism due to Hashimoto's thyroiditis. Without a history of thyroid trauma or surgery, she presented a 1.6 x 0.7 x 0.5 cm right pre-laryngeal lymph node-like mass which, on ultrasonography, appeared distinct from the gland. TSH, thyroid peroxidase antibody and thyroglobulin antibody serum levels were elevated and T4-free level was normal. Thyroid and total body 99m Tc isonitrile scintiscan showed a topic thyroid without radionuclide uptake in the nodule. Fine-needle aspiration of the nodule showed epithelial cells with nuclear atypia and oncocitic changes plus intense lymphoid infiltration and germinative center formation, simulating lymph node metastasis of papillary thyroid carcinoma. Conventional biopsy revealed a parasitic thyroid nodule with Hashimoto's chronic thyroiditis. Parasitic thyroid nodule must always be remembered so that unnecessary surgical assessment and undesirable sequels may be avoided. (author)

To compare the diagnostic accuracy of ultrasonography (US), F18-fluorodeoxyglucose positron emission tomography/CT (PET/CT), contrast enhanced CT (CECT), serum anti-thyroid antibody for detecting Hashimoto's thyroiditis in thyroid cancer patients who underwent neck surgery. A total of 150 patients with suspicious for thyroid cancer, who had previously undergone US guided needle aspiration of thyroid, were evaluated with the use of US, PET/CT, CECT and serum anti-thyroid antibody. The four studies were performed within two months before neck surgery. Hashimoto's thyroiditis was confirmed by histopathological results. The diagnostic accuracy of US, PET/CT, CECT and serum anti-thyroid antibody were calculated statistically. Hashimoto's thyroiditis was diagnosed in 51 out of the 150 patients, following neck surgery. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of US were 76.5%, 92.9%, 84.8%, 88.5%, and 87.3%, respectively. The corresponding values of PET/CT were 37.3%, 96.0%, 82.6%, 74.8%, and 76.0%, and CECT were 62.7%, 89.9%, 76.2%, 82.4%, and 80.7%, and serum anti-thyroid antibody level were 90.2%, 93.9%, 88.5%, 94.9%, and 92.7%, respectively. McNemar test revealed significant difference among PET/CT and others, but no significant differences among US, CECT and serum anti-thyroid antibody. Overall, serum anti-thyroid antibody showed most accurate diagnostic performance. In detecting Hashimoto's thyroiditis, serum anti-thyroid antibody showed higher diagnostic accuracy than others. US also showed relatively high diagnostic accuracy.

During the course of the autoimmune thyroid diseases, ultrasonography change parallel to histopathology. Vitamin D is associated with autoimmune diseases and thus can affect thyroid blood flow. Our aim was to investigate the relationship between vitamin D insufficiency/deficiency and thyroid hemodynamic indices in patients with Hashimoto thyroiditis. A total of 93 patients who presented to Sakarya University Endocrinology outpatient clinic from April to September 2016 and diagnosed with Hashimoto thyroiditis were included in this study. Clinical and serologic data, thyroid antibodies and 25(OH)D3 were evaluated. Mean peak systolic velocity(mPSV), mean end-diastolic velocity (EDV), mean resistive index (RI) flows of superior and inferior thyroid arteries were measured with B-mode Doppler ultrasonography. Vitamin D insufficiency/deficiency was detected in 59 (63.4%). TPO Ab and TgAb levels were found higher in patients with vitamin D insufficiency/deficiency. In the normal vitamin D group, superior thyroid artery mPSV (32.21±6.73cm/s) and EDV(13.27±2.80 cm/s) were higher than in the low vitamin D group [mPSV (28.32±8.99cm/s) and EDV(10.67±3.68 cm/s)] (P=0.034, P=0.001, respectively). Inferior thyroid artery EDV value was higher in the normal compared to the low vitamin D group (0.032). RI measured in all arteries were higher in the vitamin D insufficient/deficient group compared to the Vitamin D normal group (p=0.001). Vitamin-D insufficiency/deficiency has led to reduced parenchymal blood supply and increased micro-vascular resistance in Hashimoto thyroiditis patients.

Intrathyroid lymphoid tissue is accrued in Hashimoto thyroiditis (HT). Histologically, this acquired lymphoid tissue bears a close resemblance to mucosa-associated lymphoid tissue (MALT) and can evolve to lymphoma. To demonstrate the morphological, and immunohistochemical profiles of Hashimoto thyroiditis and to ascertain the importance of light chain restriction in distinguishing HT with extensive lymphoplasmacytoid infiltrate from MALT lymphoma. We studied histopathologically and immunohistochemically (CD20, CD3, Igk, Igl and cytokeratin) 30 cases of HT for evaluation of the lymphoid infiltrate and the presence of lymphoepithelial lesions (LELs). Distinguishing between early thyroid lymphoma and HT was evaluated by light chain restriction. These findings were compared with two cases of primary thyroid lymphoma. The histopathological findings were characteristic of HT. Immunohistochemistry confirmed inconspicuous, rare B-cell LELs as well as a prominent T-lymphocyte population. Testing for light chain restriction showed polyclonal population of plasma cells. The cases of MALT lymphoma had distinct destructive lymphoepithelial lesions, B-cell immunophenotyping and showed kappa light chain restriction in the plasmacytoid population. Hashimoto thyroiditis differs both histopathologically and immunohistochemically from thyroid lymphoma. In suspicious cases, immunohistochemistry could be helpful in reaching a definitive diagnosis.

Full Text Available One of the minimally invasive thyroidectomy challenges is the application of this technique in the surgical treatment of thyroid cancer. The use of minimally invasive open approach in co-existence of thyroid cancer with Hashimoto thyroiditis is well known provocation to the skills of the surgeon working in the field of thyroid surgery.Aim: To report our results and to present the possibilities of minimally invasive open approach in the surgical treatment of thyroid carcinoma and coexistent Hashimoto thyroiditis. Patients and methods: For the period from 2008 to 2011, 641 patients were operated on in our clinic using minimally invasive open approach. In 32 of these patients presence of Hashimoto thyroiditis was found in combination with thyroid cancer. All patients were females, 26 to 46 years age. Patients were selected according to designed and accepted for our institution criteria. The procedures were performed using ultrasound (harmonic shears (Harmonic Focus® and Harmonic Ace®, Ethicon Endo-Surgery. The operative time, incidence, type and severity of complications, length of hospital stay, safety and reliability of the surgical procedure were analyzed. Results: The operative incision length in all cases was between 2.0-2.5 cm. In 27 patients papillary thyroid carcinoma and in 5 patients – follicular variant of the neoplasm were found. The tumor size ranged between 0.5 and 1.5 cm. In all patients total thyroidectomy using harmonic scalpel was performed. Lymph node metastases in the central neck compartment were not found in any of the cases. The rate, type and severity of complications did not exceed those for patients who underwent conventional thyroidectomy. All patients leaved the hospital in the first 24 postoperative hours. The follow-up did not reveal remnant thyroid tissue in thyroid gland bed or recurrence of the disease.Conclusions: Our results demonstrate the feasibility and reliability of minimally invasive open approach with

To demonstrate sonographic features of Hashimoto's thyroiditis according to the thyroid function. We reviewed 54 thyroid ultrasonographic examinations of untreated Hashimoto's thyroiditis. We reviewed thyroid ultrasonographic examinations and focused on the presence of ill-defined low echoic lesions and glandular enlargement. We performed another thyroid ultrasonographic examination of 14 healthy volunteers, in order to obtain normal size of thyroid gland. Comparison was made between these morphologic characteristics and functional stage of the disease. The mean diameter of thyroid gland was 2.16 {+-} 0.43 cm in patients with Hashimoto's thyroiditis, and 1.41 {+-} 0.42 cm in normal control group of the thyroid gland. There was no statistically significant relationship between thyroid function and size. There was morphologic abnormalities in 46 patients (85%). Among them, 7 patients revealed diffuse low echogenicity in the entire thyroid gland, 32 patients showed peripherally located, ill-defined focal hypoechoic lesion, and 7 patients showed solitary or multiple. well-defined nodular lesions. Decreased echogenicity of the thyroid gland was related to hypothyroid status. Hashimoto's thyroiditis has specific morphologue characteristics in ultrasonographic features, which are well correlated with thyroid function.

The aim of report is to present a case of a rare diffuse sclerosing variant of a papillary thyroid carcinoma. A 15-year old girl referred for ultrasound examination because of painless thyroid swelling lasting 10 days before. An ultrasound of the neck showed diffusely changed thyroid parenchyma, without nodes, looking as lymphocytic thyroiditis Hashimoto at first, but with snow-storm appearance, predominantly in the right lobe. Positive thyroid peroxidase antibodies (TPO-AT) also suggested Hashimoto thyroiditis. Repeated US-FNAB (fine needle-aspiration biopsy) of the right lobe revealed diffuse sclerosing variant of papillary thyroid carcinoma and patient underwent total thyreoidectomy. Patohistologic finding confirmed diffuse sclerosing variant of a papillary thyroid carcinoma in the both thyroid lobes and several metastatic lymph nodes. Two months later patient recived radioablative therapy with 3700 MBq (100 mCi) of 1-131 followed by levothyroxine replacement. At the moment, patient is without evidence of local or distant metastases and next regular control is scheduled in 6 months. In conclusion, a diffuse sclerosing variant is rare form of papillary thyroid carcinoma that echographically looks similar to Hashimoto thyroiditis and sometimes could be easily overlooked.

Hashimoto's thyroiditis is the most common autoimmune thyroid disorder in the pediatric age range. Measurement of thyroid gland size is an essential component in evaluation and follow-up of thyroid pathologies. Along with size, tissue elasticity is becoming a more commonly used parameter in evaluation of parenchyma in inflammatory diseases. The aim of the current study was to assess thyroid parenchyma elasticity by shear-wave elastography in pediatric patients with Hashimoto's thyroiditis; and compare the elasticity values to a normal control group. In this study; thyroid glands of 59 patients with a diagnosis of Hashimoto's thyroiditis based on ultrasonographic and biochemical features, and 26 healthy volunteers without autoimmune thyroid disease and thyroid function disorders, were evaluated with shear-wave elastography. Patients with Hashimoto thyroiditis were further subdivided into three categories based on gray-scale ultrasonography findings as focal thyroiditis (grade 1), diffuse thyroiditis (grade 2), and fibrotic thyroid gland (grade 3). Patients with Hashimoto's thyroiditis (n = 59) had significantly higher elasticity values (14. 9 kPa; IQR 12.9-17.8 kPa) than control subjects (10.6 kPa; IQR 9.0-11.3 kPa) (p thyroiditis, 23 patients had focal thyroiditis involving less than 50% of the gland categorized as grade 1, 24 patients had diffuse involvement of the thyroid gland categorized as grade 2, and 12 patients had marked hyperechoic septations and pseudonodular appearance categorized as grade 3 on gray-scale ultrasound. Based on elastography, grade 3 patients had significantly higher elasticity values (19.7 kPa; IQR 17.8-21.5 kPa) than patients with grade 2 (15.5 kPa; IQR 14.5-17.8 kPa) and grade 1 thyroiditis (12.8 kPa; IQR 11.9-13.1 kPa) (p thyroiditis had significantly higher elasticity values than those with grade 1 thyroiditis (p thyroiditis. Our results indicate that shear-wave elastography could be used to evaluate the degree of

The purpose of this study was to evaluate the association between Hashimoto's thyroiditis and BRAF(V600E) mutation status in patients with papillary thyroid cancer (PTC) and to determine their combined association with tumor aggressiveness in PTC. A total of 1780 patients with PTC who underwent surgery were enrolled in this study. Simple and multiple analyses were performed to determine the association between Hashimoto's thyroiditis and the BRAF(V600E) mutation in PTC. Hashimoto's thyroiditis was present in 11.5% of patients (204/1780) with PTC. Multiple logistic regressions showed that BRAF(V600E) (odds ratio [OR] = 0.493; 95% confidence interval [CI] = 0.360-0.678) and the female sex (OR = 7.146; 95% CI = 3.408-18.347) were independent factors associated with Hashimoto's thyroiditis in PTC. BRAF(V600E) mutation and the Hashimoto's thyroiditis-negative PTC group were associated with aggressive disease (OR = 3.069; 95% CI = 1.654-5.916). Hashimoto's thyroiditis was associated less frequently with BRAF(V600E) , and frequently with the female sex in patients with PTC. Hashimoto's thyroiditis and BRAF(V600E) status may help to predict clinical outcome of PTC. © 2015 Wiley Periodicals, Inc.

Purpose: To evaluate color-Doppler features predictive of focal Hashimoto's thyroiditis. Materials and methods: A total of 521 patients with 561 thyroid nodules that underwent surgeries or gun biopsies were included in this study. These nodules were divided into three groups: focal Hashimoto's thyroiditis (104 nodules in 101 patients), benignity other than focal Hashimoto's thyroiditis (73 nodules in 70 patients), and malignancy (358 nodules in 350 patients). On color Doppler sonography, four vascularity types were determined as: hypovascularity, marked internal flow, marked peripheral flow and focal thyroid inferno. The {chi}{sup 2} test was performed to seek the potential vascularity type with the predictive ability of certain thyroid pathology. Furthermore, the gray-scale features of each nodule were also studied. Results: The vascularity type I (hypovascularity) was more often seen in focal Hashimoto's thyroiditis than other benignity and malignancy (46% vs. 20.5% and 19%). While the type II (marked internal flow) showed the opposite tendency (26.9% [focal Hashimoto's thyroiditis] vs. 45.2% [other benignity] and 52.8% [malignancy]). However, type III (marked peripheral flow) was unable to predict any thyroid pathology. Importantly, type IV (focal thyroid inferno) was exclusive to focal Hashimoto's thyroiditis. All 8 type IV nodules appeared to be solid, hypoechoic, and well-defined. Using 'focal thyroid inferno' as an indicator of FHT, the diagnostic sensitivity and specificity were 7.7% and 100% respectively. Conclusions: The vascularity type of 'focal thyroid inferno' is specific for focal Hashimoto thyroiditis. Recognition of this particular feature may avoid unnecessary interventional procedures for some solid hypoechoic thyroid nodules suspicious of malignancy.

Color Doppler ultrasonographic(US) features of 28 patients with Hashimato's thyroiditis were evaluated with regard to echo and color-flow patterns. Correlation of color-flow pattern with thyroid function was performed. All 28 patients showed varying degrees of diffuse enlargement of the thyroid gland and a heterogeneous echo pattern.Color-flow pattern of increased blood flow. Low to moderate, focally increased blood flow was seen in 26 patients(92.8%). Of these 26 patients, 24 patients showed subclinical hypothyroidism or euthyroidism. Two patients who showed hyperthyroidism showed several pieces of focally increased color flow, Which was noted during both systole and diastole. Diffuse, multifocal color-flow throughout thyroid gland was seen in two patients with Hashimato's thyroiditis: one with clinical hypothyroidism and the other with subclinical hypothyroidism. Even though Hashimoto's thyroiditis showed variable color-flow patterns, we believe that heterogenous parenchymal echopattern with low or moderately increased flow is a rather characteristic feature of Hashimoto's thyroiditis, and we suggest that color Doppler US provides additional information for evaluation of Hashimoto's thyroiditis

Vitamin D deficiency is associated with several autoimmune diseases. This study assessed whether vitamin D deficiency is associated with Hashimoto thyroiditis (HT). Two groups of patients were selected for which serum 25-hydroxyvitamin D (25(OH)D) levels had been measured: (1) a study group of patients diagnosed with HT as indicated by thyroid antibodies, and (2) a healthy control group. Each group was separated by sex and then controlled for age and body mass index (BMI). Groups' mean 25(OH)D levels were compared by analysis of variance (ANOVA), and percent frequencies of vitamin D sufficiency, insufficiency, and deficiency were compared with a Z-test. The correlations between 25(OH)D levels and thyroid antibodies and thyroid-stimulating hormone (TSH) levels were also tested. The mean 25(OH)D levels for the HT and control groups were significantly different in females (30.75 vs. 27.56 ng/mL, respectively) but not in males (14.24 vs. 13.26 ng/mL). HT females had a higher rate of vitamin D sufficiency (51.7% vs. 31.1%) and a lower rate of insufficiency (48.3% vs. 68.9%) relative to control females. No such differences were found in the male groups. None of the females were vitamin D deficient, but almost all males were. A significant (P = .016) positive correlation (rs = 0.436) between 25(OH)D and TPOAb was observed in males. HT is not associated with higher rates of vitamin D deficiency relative to a control group. BMI = body mass index HT = Hashimoto thyroiditis 25(OH)D = 25-hydroxyvitamin D TgAb = thyroglobulin antibody TSH = thyroid-stimulating hormone TPOAb = thyroid-peroxidase antibody VDR = Vitamin D receptor.

Currently there is a growing interest in studying systemic conditions with impact on the periodontium. The aim of this article is to determinate if there is a relation between Hashimoto's thyroiditis and periodontal disease. Founded on periodontology based on evidence and in the combination of the keywords: 'Hashimoto disease'; 'Hypothyroidism'; 'Periodontal disease'; 'Systemic Diseases'; a search and evaluation of articles was conducted in Medline, Scopus and Thomson Reuters databases, selecting 30 articles for integral analysis. There have been developed several studies, searching for a better comprehension about the complexity and pathogenesis of periodontal diseases, associated them to multiple systemic conditions. Actually, the relationship that is best described in the literature is the one with rheumatoid arthritis; however, other relations have been pointed, such as Hashimoto's thyroiditis. The identification of multiple etiopathogenic mechanisms common to Hashimoto's thyroiditis and periodontal disease allow to suspect of a relation between them. Some of these mechanisms include the proliferation of lymphocytes T helper 1 and T helper 17 and their impact on the periodontium, the dysfunction of vascular endothelium in gingival microcirculation and the influence of hypothyroidism on bone metabolism, namely on the alveolar bone. There is biological plausibility to support the establishment of an association between Hashimoto's thyroiditis and periodontal disease. However, there are not enough studies to support the existence of a causal nexus between these two pathologies, so, in the future, more studies should be conducted to determinate there relation and interaction.

Livin belongs to the family of apoptosis inhibitors. High livin expression is observed in malignancies of the gastrointestinal tract, lungs, breast, and kidneys, but it is not present in differentiated adult tissues. In some malignant processes, anti‑livin antibodies are present. The aim of the study was to evaluate the prevalence of anti‑livin antibodies in Hashimoto thyroiditis, a disease characterized by rapid and widespread thyrocyte apoptosis. The study comprised 65 women with Hashimoto thyroiditis and the control group of 40 healthy women. In the majority of the patients, clinical manifestations of hypothyroidism were observed; all patients had high levels of serum antithyroid peroxidase antibodies. A solid‑phase radioimmunoassay in livin‑coated polyethylene tubes using 125I-labeled protein A was used to determine anti-livin antibodies. Significant amounts of anti-livin antibodies were reported in 18 patients (26.8%); 3 patients (4.6%) had borderline antibody levels; while in controls only 1 patient was positive (2.5%, P Hashimoto thyroiditis, an autoimmune process is more general and involves numerous autoantibodies including an antibody against apoptosis inhibitor - livin. Anti‑livin antibodies cannot serve only as a marker of malignancy because they are also present in autoimmune processes.

Full Text Available Autoimmune thyroid diseases (ATD are multifactorial conditions that result from genetic predisposition in combination with environmental risk factors. Helicobacter pylori infection as an environmental risk factor has been proposed to imitate the antigenic components of the thyroid cell membrane and may play a leading role in the onset of the autoimmune diseases, such as Hashimoto thyroiditis. The aim of this study was to investigate the association between Helicobacter pylori (HP infection and Hashimoto's thyroiditis (HT. The participants in this case-control study included 43 patients affected by Hashimoto's thyroiditis, and 40 healthy individuals without history of autoimmune disease as the control group. Anti HP IgG and anti-TPO antibodies were determined using ELISA method. Results were considered positive when the IgG anti-HP value was higher than 30 IU/ml and the anti-TPO autoantibody value was higher than 75 IU/ml. The mean TSH level was 18.3±16.8 IU/ml for patients and 2.8±1.2 IU/ml for the control group (P<0.001. 46.5% of the patient group and 10.8% of the control group were infected with HP. The association between HP and Hashimoto's thyroiditis was statistically significant (Odds Ratio=7.2, 95%, Confidence Interval: 2.0- 28.8, P<0.001. The findings show that, there is an association between HP and Hashimoto's thyroiditis. To establish a definite correlation between them, more detailed studies with a more specialized examination and precise consideration regarding species of HP, genetic polymorphism of the host and investigation of environmental factors are needed.

The reported incidence of thyroid carcinoma in Hashimoto's thyroiditis varies widely. For this reason the specific subpopulation of patients with Hashimoto's thyroiditis and a solitary cold nodule was analyzed. Between 1972 and 1984 we operated on 146 consecutive patients with solitary cold nodules and Hashimoto's thyroiditis. There were 47 carcinomas, for an incidence of 32%. The mean age of the 146 patients was 43 1/2 years (median 44 years), with 126 females and 20 males. There was a history of prior head and neck radiation exposure in 54 patients, with a 33% incidence of thyroid carcinoma. The 92 patients without a history of radiation exposure had a 31.5% incidence of carcinoma. The frequency of multicentricity (bilateralism) was 33% in the group that underwent radiation and 24% in the group that did not. To date, with a mean follow-up of 4.7 years, there have been no deaths and no evidence of recurrence. In conclusion, we report a 32% incidence of thyroid carcinoma in patients with Hashimoto's thyroiditis and a solitary cold nodule, with no apparent difference between the patients with or without a history of radiation exposure, although there was a higher incidence of bilateralism (33% versus 24%) in the carcinomas of the patients with a history of head and neck irradiation. We suggest that the operative management of these patients is total thyroidectomy for those with a history of head and neck radiation and thyroid lobectomy for patients with no history of radiation, followed by contralateral lobectomy if a carcinoma is demonstrated

To evaluate the parenchymal elasticity of the thyroid gland with acoustic radiation force impulse imaging in pediatric patients with Hashimoto thyroiditis and to compare it with healthy volunteers. Twenty-six patients with Hashimoto thyroiditis and 26 healthy volunteers between 6 and 17 years were included. The shear wave velocity (SWV) values of both thyroid lobes in both groups were evaluated. The age and sex characteristics of the controls and patients with Hashimoto thyroiditis were similar. The SWV of the thyroid gland in patients with Hashimoto thyroiditis (mean ± SD, 1.67 ± 0.63 m/s) was significantly higher than that in the control group (1.30 ± 0.13 m/s; P thyroid lobes in both groups. A receiver operating characteristic curve analyses showed an optimal cutoff value of 1.41 m/s, with 73.1% sensitivity, 80.8% specificity, a 79.2 % positive predictive value, and a 75.0% negative predictive value (area under the curve, 0.806; P Hashimoto thyroiditis, there was a positive correlation between the SWV values versus anti-thyroperoxidase (Pearson r = 0.46; P = .038). There were no correlations between age, body mass index, thyroid function test results, and anti-thyroglobulin values and versus SWV values. Also, no significant differences were seen between the groups for gland size, gland vascularity, and l-thyroxine treatment. Acoustic radiation force impulse elastography showed a significant difference in the stiffness of the thyroid gland between children with Hashimoto thyroiditis and the healthy group. Using acoustic radiation force impulse elastography immediately after a standard ultrasound evaluation may predict chronic autoimmune thyroiditis. © 2017 by the American Institute of Ultrasound in Medicine.

We used electronic databases (PubMed, EMBASE, Cochrane Library) to search and collect all published articles about the association between HT and vestibular disorders. Several observational and retrospective studies have postulated a relationship between thyroid autoimmunity and vestibular disorders. In most cases, an appropriate control group was lacking, and the impact of thyroid functional status could not precisely be established. In recent years, two well-designed prospective studies have provided convincing evidence that the association is not random. One article reported that patients with Ménière disease (MD) had a significantly higher prevalence of positive anti-thyroid autoantibody as compared to healthy controls. Moreover, more than half of MD patients had either positive anti-thyroid or non-organ-specific autoantibody titers, compared to less than 30% of both patients with unilateral vestibular paresis without cochlear involvement and healthy controls. Another study found that patients with benign paroxysmal positional vertigo (BPPV) had significantly higher serum thyroid-stimulating hormone and antithyroid autoantibody levels than healthy controls. Additionally, almost one-fifth of euthyroid patients with HT had signs of BPPV. The published results indicate that patients with MD or BPPV are potential candidates to also develop HT. Thus, in HT patients, the presence of even slight symptoms or signs potentially related to vestibular lesions should be carefully investigated. AITD = autoimmune thyroid disease; BPPV = benign paroxysmal positional vertigo; EH = endolymphatic hydrops; HT = Hashimoto thyroiditis; L-T 4 = L-thyroxine; MD = Ménière disease; PS = Pendred syndrome; Tg = thyroglobulin; TPO = thyroid peroxidase; TSH = thyroid-stimulating hormone.

Fetuin-A levels are reported to be low as a negative acute phase reactant in systemical inflammatory situations. Hashimoto thyroiditis is characterized with inflammation. In this study, we hypothesised that the serum fetuin A levels could be found to be low due to inflammation in patients with Hashimoto thyroiditis. For this purpose, serum fetuin A levels in patients with Hashimoto thyroiditis were compared with those in healthy subjects. A total of 85 participants (11 male, 74 female, mean age: 38.60±10.14 years) were included. The patient group consisted of 44 Hashimoto thyroiditis patients with subclinical hypothyroidism (7 male, 37 female) and the control group consisted of 41 healthy subjects (4 male, 37 female). Groups were compared according to their demographic, anthropometric and biochemical data and serum fetuin-A levels. Correlation analysis was used for determining the relation between fetuin A levels and clinical parameters. Fetuin-A levels of the patient group were found lower than those of the control group (0.58±0.50 g/L versus 1.53±1.60 g/L, P=0.001). Fetuin-A levels were not correlated with clinical parameters such as TSH, C-reactive protein, body mass index, waist circumference, blood pressure, glucose, and lipids. These findings supported the hypothesis that serum fetuin A levels could be found to be low as a negative acute phase reactant in patients with Hashimoto thyroiditis. Fetuin A can be considered as an indicator of inflammation in Hashimoto thyroiditis.

Objective. The risk of atherosclerotic heart disease is increased in autoimmune thyroiditis, although the reason is not clear. Lipoprotein(a) (Lp(a)) excess has been identified as a powerful predictor of premature atherosclerotic vascular diseases. The aim of this study is to investigate the relationship between Lp(a) levels and thyroid hormones in Hashimoto patients. Method. 154 premenopausal female Hashimoto patients (48 patients with overthypothyroid (OH), 50 patients with subclinical hypothyroid (SH), and 56 patients with euthyroid Hashimoto to (EH)) were enrolled in this study. The control group consists of 50 age matched volunteers. In every group, thyroid function tests and lipid parameters with Lp(a) were measured. Lp(a) excess was defined as Lp(a) > 30 mg/dL. Results. Total-C, LDL-C, TG, and Lp(a) levels were increased in Hashimoto group. Total-C, LDL-C, and TG levels were higher in SH group than in the control group. Total-C and LDL-C levels were also higher in EH group compared to controls. Lp(a) levels were similar in SH and EH groups with controls. However, excess Lp(a) was more common in subclinical hypothyroid and euthyroid Hashimoto group than in the control group. Conclusion. The Total-C and LDL-C levels and excess Lp(a) were higher even in euthyroid Hashimoto patients. Thyroid autoimmunity may have some effect on Lp(a) and lipid metabolism.

In the presence of normal human lymphocytes, decomplemented sera from twentynine out of thirty-nine patients with Hashimoto thyroiditis caused significant lysis of thyroglobulin-coated chicken red blood cells, as estimated by the release of 51Cr; the mean% specific 51Cr release being 14·1 ± 1·9 (SEM). Serum from twenty-one control subjects studied concurrently caused no significant lysis of thyroglobulin-coated chicken red blood cells; the mean% specific 51Cr release being −1·6±0·7 (SEM). The degree of cytotoxicity correlated with the titre of thyroglobulin antibodies in the serum, determined by tanned red cell haemagglutination. The active component in the Hashimoto serum was localized in the 19S fraction, was unaffected by pre-absorption with anti-human IgM serum, but was neutralized by pre-absorption with anti-human IgG serum. These findings suggest that the cytotoxic activity of serum from patients with Hashimoto thyroiditis is due to the presence of thyroglobulin antibody of the IgG class in the form of complexes, either alone or with antigen. It is postulated that non-specific lymphocytes may play an important role in the pathogenesis of Hashimoto thyroiditis, being activated by the presence in the gland of thyroglobulin antibody, either alone or in the form of complexes attached to thyroid cells.

A case of parasitic thyroid nodule is presented. The patient was a non symptomatic 53-year-old white woman, on irregular course of L-thyroxine to treat hypothyroidism due to Hashimoto's thyroiditis. Without a history of thyroid trauma or surgery, she presented a 1.6 x 0.7 x 0.5 cm right pre-laryngeal lymph node-like mass which, on ultrasonography, appeared distinct from the gland. TSH, thyroid peroxidase antibody and thyroglobulin antibody serum levels were elevated and T4-free level was normal. Thyroid and total body {sup 99m} Tc isonitrile scintiscan showed a topic thyroid without radionuclide uptake in the nodule. Fine-needle aspiration of the nodule showed epithelial cells with nuclear atypia and oncocitic changes plus intense lymphoid infiltration and germinative center formation, simulating lymph node metastasis of papillary thyroid carcinoma. Conventional biopsy revealed a parasitic thyroid nodule with Hashimoto's chronic thyroiditis. Parasitic thyroid nodule must always be remembered so that unnecessary surgical assessment and undesirable sequels may be avoided. (author)

The incidence of cricoarytenoid joint fixation in case of rheumatoid arthritis is 17 to 33%. In later stages of rheumatoid arthritis, a gradual fixation of cricoarytenoid joint develops and both halves of the larynx become less movable which calls for endotracheal intubation; while total fixation of this joint demands surgical tracheotomy. Hashimoto thyroiditis can display symptoms which are difficult to distinguish from the ones present in total fixation of cricoarytenoid joint caused by rheumatoid arthritis. A 60-year-old woman in terminal stage of rheumatoid arthritis and Hashimoto thyroiditis, diagnosed after clinical and other examinations. She was treated for strident breathing with surgical tracheotomy. The microscopic examination of the larynx with the use of laryngoscopic pincers suggested the immovability of the right and very limited movability of the left arytenoid cartilage. A computerized endovideostroboscopy showed only passive vertical vibrating movements of the right vocal cord and irregular vibrations of the left vocal cord. Total fixation of the cricoarytenoid joint can be caused by many pathological processes, but so far references have shown no case of rheumatoid arthritis and Hashimoto thyroiditis. In differential diagnostics, one of many examinations is the microscopic examination of the larynx, but it is very important to determine the movability of the arytenoid cartilage with the use of appropriate instruments in total endotracheal anaesthesia while the patient is fully relaxed. Movements in cricoarytenoid joints in patients with Hashimoto thyroiditis and the same conditions are preserved.

Elastography is a method which assesses the risk of the malignancy and provides information about the degree of hardness in tissue. Hashimoto's thyroiditis, autoimmune lymphocytic infiltration and fibrosis, is considered to be a very common disease that is able to change the hardness of the tissue. The diagnostic value of elastography of this group of patients has not previously been reported. In our study, we aimed to determine the diagnostic value of elastography in 283 patients (255 female, 28 male) with Hashimoto's thyroiditis. Elastography score and index were measured with real-time ultrasound elastography (Hitachi(®) EUB 7000 HV machine with using 13 MHz linear transducer). The outcome of this measure shows that malignant nodules were with higher elastography scores (ES) and strain indexes (SI) values. ES ≥3 were observed in 16/20 malignant and 130/263 benign nodules, respectively. The area under the curve (AUC) for the elasto score (AUC) was 0.72 (p = 0.001), and AUC for the strain index was 0.77 (p Hashimoto patients although sensitivity and specificity decreases in Hashimoto in this population.

Currently, there is an inadequate number of studies on nodule and malignancy development in children and adolescents with Hashimoto thyroiditis (HT). Patients who were diagnosed with HT between 2004 and 2013 were included in the study. The HT diagnosis was made with a heterogeneous appearance on thyroid ultrasonography and the elevation of antithyroid peroxidase and/or anti-thyroglobulin antibodies. Fine-needle aspiration biopsy (FNAB) was performed in cases with a nodule size >1 cm or who had ultrasonography findings indicating malignancy. A total of 39 (13%) thyroid nodules were detected in 300 patients with a diagnosis of HT. Papillary thyroid carcinoma (PTC) was diagnosed in 2 of the 12 cases in whom FNAB was performed. The thyroid nodule was detected at the same time as HT in the 2 cases with malignancy. The PTC diagnosis was made 2 years after the HT diagnosis in the first case and 3 years later in the second case. The largest diameter of the thyroid nodule was 5 mm in both cases. The thyroid nodule rate on an HT background was found to be 13%, and the thyroid malignancy rate was 0.67% in our study. © 2016 S. Karger AG, Basel.

IgG4-related disease is a newly identified syndrome characterized by high serum IgG4 levels and increased IgG4-positive plasma cells in involved organs. The incidence of IgG4-related thyroiditis in the Caucasian population of Europe is unknown. We investigated formalin-fixed thyroid gland samples of 216 patients (191 Hashimoto's thyroiditis, 5 Riedel's thyroiditis, and 20 goiters, as controls), morphologically, and immunohistochemically. Cases were divided into two groups: IgG4-related Hashimoto's thyroiditis (24 cases) together with Riedel thyroiditis (1 case) and 171 non-IgG4-related thyroiditis. Compared to the non-IgG4-related cases, IgG4-related thyroiditis showed a higher IgG4/IgG ratio (0.6 vs. 0.1, p thyroiditis was diagnosed in 23 of the 24 IgG4-related cases (96 %) and in 13 of 167 (18 %, p > 0.001) non-IgG4-related cases. The single case of IgG4-related Riedel's thyroiditis also showed a higher median IgG4 plasma cell count (56.3 vs. 14.3) and a higher IgG4/IgG ratio (0.5 vs. 0.2) than the four cases of non-IgG4-related Riedel's thyroiditis. Our data suggests the incidence of IgG4-related disease (IgG4-RD) of the thyroid gland in Europe is considerably lower than that observed in other studies. A significant elevation of IgG4-positive plasma cells was only found in a small group of Hashimoto's thyroiditis and then accompanied by intense fibrosis, indicating an association with IgG4-RD. Morphologically, IgG4-RD of the thyroid gland differs from that in other organ systems, exhibiting a dense fibrosis without intense eosinophilia or obliterative phlebitis.

Full Text Available Background. Simultaneous presence of Hashimoto's thyroiditis and papillary thyroidal carcinoma in thyroidal gland with papillary carcinoma association in thyroglossal duct is quite rare. The questions like where the original site of primary process, is where metastasis is, what the cause of coexisting of these diseasesis present a diagnostic dilemma. Case report. We presented a case of a 53-year old female patient, with the diagnosis of Hashimoto's thyroiditis and symptoms of subclinical hypothyreosis and nodal changes in the right lobe of thyroidal gland, according to clinical investigation. Morphological examination of thyroidal gland, ultrasound examination and scintigraphy with technetium (Tc confirmed the existence of nonhomogenic tissue with parenchyma nodular changes in the right lobe of thyroidal gland that weakly bonded Tc. Fine needle biopsy in nodal changes, with cytological analyses showed no evidence of atypical thyreocites. Hashimoto's thyroiditis was confirmed on the basis of the increased values of anti-microsomal antibodies, the high levels of thyreogobulin 117 ng/ml and TSH 6.29 μIU/ml. The operation near by the nodular change in the right lobe of thyroidal gland revealed pyramidal lobe spread in the thyroglossal duct. Total thyroidectomia was done with the elimination of thyroglossal duct. Final patohystological findings showed papillary carcinoma in the nodal changes pT2, N0 and in the thyroglossal duct with the presence of Hashimoto's thyroiditis in the residual parenchyme of the thyroid gland. After the surgery the whole body scintigraphy with iodine 131 (131I did not reveal accumulation of 131I in the body, while the fixation in the neck was 1%. After that, the patient was treated with thyroxin with suppressionsubstitution doses. Conclusion. Abnormality in embrional development of thyroidal tissue might be the source of thyroidal carcinoma or the way of spreading of metastasis of primary thyroidal carcinoma from thyroid

The authors examined 155 autopsy cases of Hashimoto's thyroiditis in the Life Span Study sample including both A-bomb survivors and controls in Hiroshima and Nagasaki (1954 to 1974). Hashimoto's thyroiditis was classified into lymphoid, diffuse and fibrous types and the following results were obtained. No difference existed in the effects of A-bomb radiation in the incidence and ATB (At the time of the A-bomb). The ration of males to females did not reveal statistical significance, even though reversed ratio was noted in the high dose group. The variation of thyroid gland weight in T65 dose or by variant showed no significant pattern, even though the smallest average weight was found in the highest radiation exposure group. The complication in the patients with Hashimoto's thyroiditis were noted to have high prevalance of ovarian cancer and low prevalence of stomach cancer and total cancer. Only two patients with Hashimoto's thyroiditis were found to be complicated with thyroid carcinoma. Among collagen diseases, the prevalence of rheumatic fever and rheumatoid arthritis was high as complication. And the prevance of combined diseases suggested that no late effect of A-bomb radiation existed. (author)

We report the case of a 68-year-old patient with a known paravertebral malignant schwannoma, sent to us for postoperative staging. A combined whole-body PET/CT scan showed only poor 18 F-fluorodeoxyglucose uptake in the region of the primary tumor but distinct increased fluorodeoxyglucose uptake in the left and right thyroid gland. Thyroid sonography showed two hypoechogenic nodules. Ultrasound-guided fine-needle aspiration biopsy of one nodule showed oxyphil transformed cells, compatible with malignancy. Based on these findings, the patient underwent a subtotal thyroidectomy. Histopathology of the specimen revealed a chronic follicular Hashimoto's thyroiditis. This case demonstrates that Hashimoto's thyroiditis can mimic thyroid cancer in PET but also in sonography and fine-needle aspiration biopsy. (orig.)

CEREBRAL CAVERNOUS MALFORMATION COEXISTING WITH PITUITARY ADENOMA, HASHIMOTO THYROIDITIS AND MENTAL ILLNESS: FIRST CASE REPORT.

Full Text Available Cerebral Cavernous Malformations (CCMs are vascular lesions involving brain capillaries. They may occur sporadically or be inherited as autosomal dominant character. Due to incomplete penetrance, CCMs incidence is underestimated and, overall sporadic cases, are often accidentally diagnosed. Rarely CCMs are linked to other pathological conditions. Here we present the first case in literature of a young woman affected by sporadic CCM, pituitary adenoma, Hashimoto thyroiditis and mental illness of unknown etiology. Symptoms’ analysis suggests that she may suffer of Hashimoto encephalopathy (HE, a condition that in very few cases develops together with Hashimoto thyroiditis. Genetic bases of HE are still unknown and symptomatology is very heterogeneous. This paper is a preliminary report of the case and is focused on complexity of clinical manifestations that makes the diagnosis uncertain. If our hypothesis will be confirmed by further analysis, our aim will be to clarify genetic causes of HE.

A minute focus of extranodal marginal zone B-cell lymphoma arising in Hashimoto thyroiditis diagnosed with PCR after laser capture microdissection: a case report

Full Text Available Abstract Background Primary thyroid gland lymphomas are uncommon tumours that occur in the setting of lymphocytic thyroiditis or Hashimoto's disease in almost all cases. In this condition a distinction between an inflammatory lymphoid infiltrate and a low grade lymphoma may be extremely difficult and precise criteria are necessary for a correct diagnosis. Patient and methods We report a case of a minute focus of primary extranodal marginal zone B-cell lymphoma (EMZBCL, incidentally discovered in a 63-year-old man with Hashimoto thyroiditis (HT and diagnosed by means of polymerase chain reaction (PCR after laser capture microdissection. The histological examination of surgical specimen confirmed the diagnosis of HT and showed a minute focus of dense lymphoid infiltrate (less than 4 mm in diameter, composed by centrocyte-like cells forming MALT balls. Immunoistochemistry was not useful. A microscopic focus of EMZBCL was suspected on the basis of morphological features. PCR assays revealed the rearrangement of the heavy chain of immunoglobulins only in the microdissected suspicious area, confirming the diagnosis of EMZBCL. Conclusion Our finding suggests that in cases of autoimmune thyroiditis a careful examination of the thyroid specimen is warranted, in order to disclose areas or small foci of lymphomatous transformation. Furthermore, in difficult cases with doubtful immunohistological findings, ancillary techniques, such as molecular studies, are necessary for a conclusive diagnosis.

In 1912 Japanese physician Hashimoto Hakaru described 4 patients with chronic thyroid disease. The histopathology findings exactly 100 years ago described lymphocyte infiltration, fibrosis, parenchymal atrophy and eosinophilic changes of some acinar cells. Those findings are typical for the autoimmune thyroid disease named by the author Hashimoto thyroiditis or lymphocytic thyroiditis. Hashimoto thyroiditis: The pathophysiology of thyroid autoimmunity during the past decades was described in details. Many thyroid antigens were identified (thyroid - stimulating hormone or TSH, thyroglobulin, thyreoperoxidase) and antibodies are directed towards them. Thyreocyte is also able to function as antigen presenting cell. It presents antigen on its surface and expresses MHC class II and class I molecules. Etiology of autoimmune thyroiditis combines genetic and environmental factors. Genetic factors dominate, and influence with about 80% on the occurrence of immunity. Some HLA genes (HLA-DR3, HLA-DR4, HLA-DR5 and HLA-DQA) and some non-HLA genes (cytotoxic T-lymphocyte antigen 4 -CTLA-4, CD40 gene, gene for protein tyrosine phosphatase 22 -PTPN22, thyroglobulin and TSH gene) are involved. 20% of etiology is attributed to environmental factors (smoking, iodine intake, selenium deficiency, pollution, infectious conditions, physical and emotional stress) and physiological states (puberty, rapid growth, pregnancy, menopause, aging, female gender). Although Hashimoto thyroiditis is known for many years, it is still sometimes presented with surprisingly diverse clinical entities and frequently astonishes many physicians. A case of a female patient with long-standing hypothesis (fine needle aspiration showed lymphocytic infiltration, thyreoperoxidase antibodies were positive) is presented. During the postpartum period, complicated with septic endometritis a new onset of hyperthyreosis appeared. The etiology of hyperthyroidism was unclear, with three possible explanations. The first

Abstract The purpose of this study was to investigate the risk factors for central and lateral neck lymph node metastases in papillary thyroid carcinoma (PTC) and multifocal papillary thyroid carcinoma (MPTC), particularly when associated with Hashimoto thyroiditis (HT). A retrospective analysis of 763 consecutive patients who underwent total thyroidectomy with bilateral central neck dissection in the First Affiliated Hospital, College of Medicine, Zhejiang University between October 2011 and October 2014 was conducted. All patients had formal histological diagnoses of HT. Multivariable logistic regression analysis was performed to identify risk factors of neck lymph node metastases. Our study identified 277 PTC patients with HT and showed comparatively low rates of central lymph node metastases (CLNM) compared with the PTC patients without HT (37.2% versus 54.7%, P thyroid peroxidase antibody >140 IU/mL was established as the most sensitive and specific level for the prediction of MPTC based on receiver operating characteristic curve analyses. Thyroid peroxidase antibody, age, tumor size, and multifocality exhibited the ability to predict CLNM in PTC with HT patients with an area under the curve of 81.1% based on a multivariate model. Hashimoto thyroiditis was associated with increased prevalences of multifocality and capsular invasion. In contrast, HT was associated with a reduced risk of CLNM in PTC and MPTC patients, which indicated a potential protective effect. We found that the prognostic prediction model was applicable for predicting multifocality and CLNM in PTC patients with HT. PMID:26871795

Melkersson-Rosenthal syndrome (MRS) is a rare disorder of unknown cause. The classical triad of MRS is orofacial edema, recurrent facial paralysis, and a fissured tongue. We present a 9-year-old girl with a recurrent peripheral facial paralysis. She experienced the first episode of a peripheral facial paralysis on the same side without orofacial swelling and lingua plicata 1 year ago. She was diagnosed with Hashimoto thyroiditis 9 months earlier, as confirmed by an endocrinologic investigation. While the patient was hospitalized with recurrent facial paralysis, we found that serum levels of free thyroxine (1.3 ng/dL) and thyrotropin (0.4 uIU/mL) were within normal range, but the level of antithyroperoxidase antibodies (772.0 IU/mL) was very increased. She had been taking an oral prednisolone orally for 2 weeks. At the 1-month follow-up, the patient's symptoms had completely disappeared. The possible correlation between MRS and autoimmune disorders has been documented in only one report, which described an adult with autoimmune thyroiditis (Hashimoto thyroiditis) and MRS. We suggest that the co-occurrence of MRS and Hashimoto thyroiditis is not coincidental but linked to autoimmunity. Copyright © 2014 Elsevier Inc. All rights reserved.

A total of fifty-two patients with Hashimoto thyroiditis were tested for delayed hypersensitivity to thyroid antigens using the leucocyte migration test. The percentage of patients showing abnormal migration in the presence of crude thyroid extract, thyroglobulin, thyroid mitochondria and thyroid microsomes was 75, 44, 54 and 34% respectively. Fifty-three control patients were studied concurrently with the same antigens and the percentage showing abnormal migration was 4, 6, 6 and 6% respectively. The antigenic activity of the mitochondrial fraction was not organ specific; both liver and kidney mitochondria interfered with the migration of leucocytes from patients with Hashimoto thyroiditis.

The reported incidence of thyroid carcinoma in Hashimoto's thyroiditis varies widely. For this reason the specific subpopulation of patients with Hashimoto's thyroiditis and a solitary cold nodule was analyzed. Between 1972 and 1984 we operated on 146 consecutive patients with solitary cold nodules and Hashimoto's thyroiditis. There were 47 carcinomas, for an incidence of 32%. The mean age of the 146 patients was 43 1/2 years (median 44 years), with 126 females and 20 males. There was a history of prior head and neck radiation exposure in 54 patients, with a 33% incidence of thyroid carcinoma. The 92 patients without a history of radiation exposure had a 31.5% incidence of carcinoma. The frequency of multicentricity (bilateralism) was 33% in the group that underwent radiation and 24% in the group that did not. To date, with a mean follow-up of 4.7 years, there have been no deaths and no evidence of recurrence. In conclusion, we report a 32% incidence of thyroid carcinoma in patients with Hashimoto's thyroiditis and a solitary cold nodule, with no apparent difference between the patients with or without a history of radiation exposure, although there was a higher incidence of bilateralism (33% versus 24%) in the carcinomas of the patients with a history of head and neck irradiation. We suggest that the operative management of these patients is total thyroidectomy for those with a history of head and neck radiation and thyroid lobectomy for patients with no history of radiation, followed by contralateral lobectomy if a carcinoma is demonstrated.

By analysing nuclide image characteristics and radioimmunoassay data of 61 cases with Hashimoto's thyroiditis (HT), HT can be classified five types as below: uneven distribution, diffusion, with hyperfunction, with nodules, nearly normal. The results of radionuclide imaging and the radioimmunoassay of all the types indicate that HT can be preliminarily diagnosed by conscientiously analysing nuclide image characteristics and radioimmunoassay data and linking clinical symptoms and signs

Background Long standing Hashimoto Thyroiditis (HT) causes shrinking and atrophy of the thyroid, but may also lead to diffuse enlargement of the gland and/or formation of nodules. These nodules should be differentiated from papillary thyroid carcinoma (PTC) and primary thyroidal non-Hodgkin lymphoma (PTL), which are possible complications of HT, and require pre-surgical diagnoses and different treatments. This study focuses on the role of fine-needle cytology (FNC) in the clinical surveillance and pre-surgical diagnosis of HT with diffuse and nodular enlargement of the gland in elderly patients. Methods Thirty-four elderly patients (≥ 65 yrs) with HT and diffuse or nodular enlargement of the thyroid underwent ultrasound (US)-guided FNC. Smears were routinely stained and evaluated; additional passes were used for flow cytometry (FC) assessment of lymphoid infiltrate in 6 cases. Results The cytological diagnosis was HT in 12 cases with prevalence of Hurtle cells in 2 cases, PTC in 1 case and PTL in 2 cases. FC assessed the reactive, non-lymphomatous nature of the lymphoid infiltrate in 5 cases and demonstrated light chain restriction, hence the lymphomatous nature of the lymphoid infiltrate in 2 cases of PTL. Conclusions FNC plays a key role in the clinical surveillance and pre-surgical diagnosis of diffuse enlargement and nodular presentation of HT in elderly patients. FNC can correctly diagnose HT, PTC and PTL indicating the need for surgery and its extension in suspicious or neoplastic cases, leaving other cases to the medical treatment and clinical surveillance.

Papillary thyroid carcinoma (PTC) is a common affliction of the thyroid gland, accounting for 70% to 80% of all thyroid cancers, whereas mucosa-associated lymphoid tissue (MALT) lymphoma of the thyroid gland is uncommon. The simultaneous occurrence of both malignancies is extremely rare. We report the case of a patient with both PTC and MALT lymphoma in the setting of Hashimoto thyroiditis. An 81-year-old female patient was first admitted with goiter and hoarseness, which was attributed to an ultrasonographic thyroid nodule. Subsequent fine-needle aspirate, interpreted as suspicious of papillary thyroid cancer, prompted total thyroidectomy. MALT lymphoma was an incidental postsurgical finding, coexisting with PTC in the setting of Hashimoto thyroiditis. Although the development of MALT lymphoma is very rare, patients with longstanding Hashimoto thyroiditis should undergo careful surveillance for both malignancies.

The present study was designed to evaluate the participation and utility of Hǘrtle cells morphological requirment and transformation under Hashimoto autoimmune thyroiditis versus Riedel´s struma. Several markers have been evaluated to detect induced activities of Hǘrtle cells. Study subject - specimens (tissue fragments) collected from TG surgery (thyroidectomy) for mollecular (receptor) diagnosis of Hǘrtle cells activities using routine histological and immunohistochemical samples. 89 cases were selected in Hashimoto thyroiditis diagnosis with Hǘrtle cells history (adenoma and adenomatous grouth of oncocytes). Markers as: TSH receptors, TTF-1, S-100 protein, also anti-TPO and anti-TG levels in blood plasm were detected. It was shown that solid cell claster-nests like agregation of oncocytes and adenomatous growth foci in parafollicular areas with anti-TPO and anti-TG antibodies levels arising while Riedel´s struma shown only large intra- and extra glandular inflammatory proliferative fibrosing process. Large positive expression of TTF-1 and S-100 protein and the negative reaction of TSH receptor factor suggest that Thyroid parenchyma disorganization and mollecular biological atypia with Hǘrtle cells are proceses due to hypothyreoidismus, as well as neuroectodermal cells prominent activities in 70% of Hashimoto cases.

We report on the case of a 86-year-old male patient with a rapidly growing nodule within the right lobe of the thyroid gland, which after hemithyroidectomy, turned out to be a mucosa-associated lymphoid tissue (MALT) lymphoma of the thyroid gland. In addition, Hashimoto's thyroiditis was reported in the thyroid tissue adjacent to the MALT lymphoma. During follow-up a second nodule emerged within the left lobe and, because of evidence of MALT lymphoma recurrence, F-18-FDG-PET was performed. F-18-FDG-PET imaged a clearly in-creased accumulation within the whole left lobe and isthmus. Thus, no differences in the degree of hypermetabolism could be imaged between the nodule and the adjacent thyroid tissue. To our knowledge, this is the first report about F-18-FDG-PET in a patient with MALT lymphoma of the thyroid. Literature search revealed only a few cases of MALT lymphomas in locations other than the thyroid gland that were studied with F-18-FDG-PET. In no case was F-18 FDG accumulation seen in the MALT lesions. However, clear F-18 FDG accumulation was reported in some patients with Hashimoto's thyroiditis. It is concluded that the intensive F-18-FDG accumulation within the whole left lobe and isthmus of the presented case was due to the coexisting Hashimoto's thyroiditis. Consequently, F-18-FDG-PET imaging does not seem to be indicated in a patient with MALT lymphoma and known Hashimoto's thyroiditis in order to evaluate the status of the MALT lymphoma. (author)

To study the prevalence of Hashimoto thyroiditis (HT), anti-thyroid autoantibodies (anti-thyroglobulin or TgAb and thyroperoxidase or TPOAb) in systemic lupus erythematosus (SLE) patients. To analyze if associated HT, TgAb and/or TPOAb influence clinical or serological profiles, disease activity and/or its cumulative damage. Three hundred and one SLE patients and 141 controls were studied for thyroid stimulating hormone, thyroxin, TgAb and TPOAb by chemiluminescence and immunometric assays. Patients' charts were reviewed for serological and clinical profiles. Activity was measured by SLE Disease Activity Index and cumulative damage by Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index for SLE. SLE patients were divided into: (i) with HT; (ii) with anti-thyroid antibodies but without HT; and (iii) without HT and without anti-thyroid antibodies, and were then compared. Furthermore, SLE patients were compared according to the number of positive anti-thyroid antibodies. Hashimoto thyroiditis prevalence in SLE was 12.6% and 5.6% in controls (P = 0.02; odds ratio = 2.4; 95% CI = 1.09-5.2). Lupus patients with HT had less malar rash (P = 0.02) and more anti-Sm (P = 0.04). Anti-Sm was more common in those with two anti-thyroid antibodies than in those with one or negative. The presence of HT or the number of positive autoantibodies did not associate either with disease activity (P = 0.95) or with cumulative damage (P = 0.98). There is a two-fold increased risk of HT in SLE patients. Anti-Sm antibodies favor this association and also double antibody positivity. Disease activity and cumulative damage are not related to HT or with autoantibodies. © 2017 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.

Full Text Available INTRODUCTION: The forkhead box P3 (FOXP3 plays a role in cell development and control. In the presence of abnormal FOXP3 expression, tumor cells may evade the immunosurveillance of lymphoid cells, the first step for the maintenance of cancer cells in the thyroid tissue. OBJECTIVE: To identify the presence of FOXP3 in papillary thyroid carcinoma (PTC with and without Hashimoto's Thyroiditis (HT. METHODS: We conducted a series study of cases collected from 2000 to 2008, when 1,438 thyroidectomies were performed. We selected those diagnosed with PTC, comprising 466 cases. 30 patients were randomly selected for purposes of immunohistochemistry with antibodies against FOXP3. RESULT: FOXP3 revealed high positivity for PTC and positive immunostaining was present in 21 (72.4% from all analyzed cases. There was no difference regarding coexistent HT or not. DISCUSSION AND CONCLUSION: In the present study, it was evidenced that the focal or diffuse FOXP3 expression was commonly observed in neoplastic cells from PTC, hence indicating that the assessment of this molecule expression in suspected cases of thyroid cancer may contribute to its diagnosis.

To evaluate the prevalence of dyslipidemia in the population of Hashimoto thyroiditis, we reviewed medical records on the consecutive 1181 cases with adult Hashimoto thyroiditis and 830 cases were adopted for the study. First, the serum TSH level increased and serum free T4 level decreased, slightly but significantly, with increasing age. There were significant positive correlations between serum TSH levels and lipid parameters such as total cholesterol (TC), triglyceride (TG), HDL-cholesterol (HDL-C), LDL-cholesterol (LDL-C), non-HDL-C and LDL-C/HDL-C ratio (L/H). In contrast, there were significant negative correlations between serum free T4 levels and all of these lipid parameters. According to the thyroid function, the cases were classified into 4 groups such as thyrotoxicosis (TT), euthyroidism (EU), subclinical hypothyroidism (SH) and overt hypothyroidism (OH). TC, HDL-C, non-HDL-C and LDL-C of TT were significantly lower than those in EU. In contrast, TC, TG, non-HDL-C, LDL-C, L/H and age of OH were significantly higher than those in EU. Interestingly, LDL-C and L/H of SH were significantly higher compared with EU. Thirty-two of SH patients were treated with small doses of levothyroxine and the effects on the lipid profile were examined. The TC, non-HDL-C, LDL-C and L/H were significantly decreased after treatment. In conclusion, the prevalence of dyslipidemia increases along with hypofunction of the thyroid and T4 replacement therapy may improve lipid profile in the cases of SH with Hashimoto thyroiditis.

To compare the frequency, size, and sonographic features of thyroid nodules in overt hypothyroid and euthyroid patients with Hashimoto thyroiditis. The study included 135 overt hypothyroid (group 1) and 74 euthyroid patients (group 2) with Hashimoto thyroiditis. The two groups were compared for presence of nodule(s), nodule numbers, and nodule sizes obtained by ultrasonography. Nodules were found in 48 (35.5%) patients in group 1 and in 24 (36.9%) in group 2 (p more than 0.05). The numbers of nodules in the group 1 and group 2, respectively, were as follows: single nodule in 12 (25%) and in 9 (33.3%) patients; 2-4 nodules in 20 (41.6%) and in 13 (48.1%) patients; and > 4 nodules in 16 (33.3%) and in 5 (18.5%) patients (p more than 0.05 for all of the results). Nodule sizes of the solitary or dominant nodule in group 1 and group 2, respectively, were as follows: less than 1 cm nodules in 27 (56.2%) and in 14 (51.8%) patients; 1-2 cm nodules in 18 (37.5%) and in 7 (25.9) patients; 2-4 cm nodules in 2 (4.1%) and in 5 (18.5%) patients and > 4 cm nodules in 1 (2%) and in 1 (3.7%) patient (p more than 0.05 for all of the results). Thyroid ultrasound examination of overt hypothyroid and euthyroid patients with Hashimoto thyroiditis reveals similarities in terms of frequency, number, size, and ultrasound features of the thyroid nodules.

BRAS, RAS, P53 (mutations. Whereas Hashimoto's thyroiditis is an autoimmune disease characterized by auto-immune destruction followed by thyroid failure and it presents RET/PTC, RAS and FAS alterations. This study aims to describe the association of Hashimoto's thyroiditis with papillary carcinoma thyroid, correlating them with demographic data and histological variants. METHODS: It was conducted a case series study of 466 patients diagnosed with thyroid papillary carcinoma from January 2000 to December 2008. Case forms were filled up with the aim to collect demographic data and histological variants. RESULTS: The present study showed a coexistence of 30% of Hashimoto's thyroiditis in patients with papillary thyroid carcinoma. Among female patients there was a higher number of Hashimoto's thyroiditis cases, p = 0.046. CONCLUSION: The case series study showed a frequency of 30% of Hashimoto's thyroiditis in cases with papillary thyroid carcinoma suggesting a noncoincidental association, which raises the possibility of a cause and effect relation between thyroiditis and carcinoma development.

We report the case of a 68-year-old patient with a known paravertebral malignant schwannoma, sent to us for postoperative staging. A combined whole-body PET/CT scan showed only poor {sup 18}F-fluorodeoxyglucose uptake in the region of the primary tumor but distinct increased fluorodeoxyglucose uptake in the left and right thyroid gland. Thyroid sonography showed two hypoechogenic nodules. Ultrasound-guided fine-needle aspiration biopsy of one nodule showed oxyphil transformed cells, compatible with malignancy. Based on these findings, the patient underwent a subtotal thyroidectomy. Histopathology of the specimen revealed a chronic follicular Hashimoto's thyroiditis. This case demonstrates that Hashimoto's thyroiditis can mimic thyroid cancer in PET but also in sonography and fine-needle aspiration biopsy. (orig.)

Hashimoto's thyroiditis is now considered the most prevalent autoimmune disease, as well as the most common endocrine disorder. It was initially described in 1912, but only rarely reported until the early 1950s. To celebrate this centennial, we reviewed the surgical pathology archives of the Johns Hopkins hospital for cases of Hashimoto's thyroiditis, spanning the period from May 1889 to October 2012. Approximately 15,000 thyroidectomies were performed at this hospital over 124 years. The first surgical case was reported in 1942, 30 years after the original description. Then, 867 cases of Hashimoto's thyroiditis were seen from 1942 to 2012, representing 6% of all thyroidectomies. Hashimoto's thyroiditis was the sole pathological finding in 462 cases; it accompanied other thyroid pathologies in the remaining 405 cases. The most commonly associated pathology was papillary thyroid cancer, an association that increased significantly during the last two decades. The most common indication for thyroidectomy was a thyroid nodule that was cytologically suspicious for malignancy. Hashimoto's thyroiditis remains a widespread, intriguing, and multifaceted disease of unknown etiology one century after its description. Advances in the understanding of its pathogenesis and preoperative diagnosis will improve recognition and treatment of this disorder, and may one day lead to its prevention. PMID:23151083

The Immunopathogenesis of Chronic Autoimmune Thyroiditis One Century after Hashimoto

Science.gov (United States)

Weetman, Anthony P

Hakaru Hashimoto described 4 patients with a hitherto unknown cause for goitre, struma lymphomatosa, a century ago. He was careful to distinguish this from Riedel thyroiditis but it has become clear that fibrosis and atrophy of the thyroid are indeed components of Hashimoto thyroiditis, and in rare cases IgG4-related sclerosing disease may be an outcome. Although the cause of the lymphocytic infiltration was unknown to Hashimoto, we now know through the pioneering studies of N.R. Rose and E. Witebsky [J Immunol 1956;76:417–427] that this condition is the archetype for autoimmune destruction as a disease mechanism. In the last two decades in particular, there has been huge interest in unravelling the genetic basis for this and related autoimmune disorders. The list of polymorphisms associated with autoimmune thyroid disease grows each year, and in the case of vitiligo, which is frequently found in association with thyroid autoimmunity, we know that 27 separate susceptibility loci account for less than 20% of the heritability of this condition. Environmental and existential factors may turn out to be just as complex in number and in interactions. We can thus imagine a ‘Swiss cheese’ model for the causation of autoimmune thyroid disease, in which the effects of cumulative weaknesses line up – like the holes in slices of cheese – to allow the catastrophic event of autoimmune destruction to occur.

Immunological Mechanisms Implicated in the Pathogenesis of Chronic Urticaria and Hashimoto Thyroiditis.

Science.gov (United States)

Berghi, Nicolae Ovidiu

2017-08-01

Autoimmunity represents the attack of the immune system of an organism against its own cells and tissues. Autoimmune diseases may affect one organ (Hashimoto thyroiditis) or can be systemic (chronic urticaria). Many factors are implicated in the pathogenesis of autoimmunity (white cells, cytokines, chemokines). Hashimoto thyroiditis has been associated with chronic urticaria in the last 3 decades in a number of clinical studies. Anti-thyroid antibodies have been documented in a proportion ranging from 10% to 30% in chronic urticaria patients in different countries from 3 continents. Two of the factors involved in the mechanism of autoimmunity are present both in the pathophysiology of Hashimoto thyroiditis and chronic urticaria. According to recent studies, IL6 is implicated in the pathogenesis of both diseases. TregsCD4+CD25+Foxp3+ cells have also been implicated in the pathological mechanisms of these 2 entities. This review offers an explanation of the clinical and statistical association between these two diseases from the pathophysiological point of view.

Hashimoto thyroiditis: a century later.

More than a century has passed since the first description of Hashimoto thyroiditis (HT) as a clinicopathologic entity. HT is an autoimmune disease in which a breakdown of immune tolerance is caused by interplay of a variety of immunologic, genetic, and environmental factors. Thyrocyte injury resulting from environmental factors results in expression of new or hidden epitopes that leads to proliferation of autoreactive T and B cells. Infiltration of thyroid by these cells results in HT. In addition to the usual type of HT, several variants such as the fibrous type and Riedal thyroiditis are also recognized. The most recently recognized variant is immunoglobulin G4(+) HT, which may occur as isolated thyroid limited disease or as part of a generalized Ig4-related sclerosing disease. The relationship between HT and Riedel thyroiditis remains unclear; however, recent evidence seems to suggest that it may also be part of the spectrum of Ig4-related sclerosing disease. HT is frequently associated with papillary thyroid carcinoma and may indeed be a risk factor for developing this type of cancer. The relationship between thyroid lymphoma and HT on the other hand appears well established.

Concomitant Graves' disease and Hashimoto's thyroiditis, presenting as primary hypothyroidism.

LENUS (Irish Health Repository)

Cronin, C C

2012-02-03

Hypothyroidism in patients with Graves\\' disease is usually the result of ablative treatment. We describe a 58 year old man with Graves\\' ophthalmopathy and pre-tibial myxoedema, who presented with spontaneous primary hypothyroidism. Circulating TSH receptor antibody activity was increased, while thyroid microsomal antibody was detectable in titres greater than one in one hundred thousand. It is likely that the TSH receptor antibody of Graves\\' disease was ineffective in stimulating hyperthyroidism because of concomitant thyroid destruction due to Hashimoto\\'s disease. Alternatively, primary hypothyroidism could have resulted from the effects of a circulating TSH receptor blocking antibody.

Resistance to thyroid hormone (RTH) is a rare autosomal hereditary disorder characterized by increased serum thyroid hormone (TH) levels with unsuppressed or increased thyrotropin concentration. It remains unknown whether the coexistence of RTH with papillary thyroid carcinoma (PTC) and Hashimoto thyroiditis (HT) is incidental or whether it possesses a genetic or pathophysiological association. In the present study, a case of RTH with PTC and HT in an 11-year-old Chinese patient was examined and the clinical presentation of RTH with PTC was discussed. In addition, the possible associations between RTH, PTC and HT were determined. HT was confirmed in the patient using an autoimmune assay and thyroid ultrasound. RTH was diagnosed on the basis of clinical manifestations, laboratory information and gene analysis, and PTC was diagnosed according to histological results. Results of BRAF V600E mutation analysis were positive. A literature review of 14 cases of RTH with PTC was included for comparison. The present case report indicates an association of RTH with PTC and HT coexistence in the patient. Close follow-up, histological evaluation and BRAF V600E mutation detection should be performed in each RTH case with HT, since a persistent increase in TSH may be a risk factor for the development of thyroid neoplasm.

Neck pain is a common complain, being in most cases due to non-thyroidal causes. However, a minority of patients suffer from painful thyroid diseases. Among them, sub-acute thyroiditis (SAT) is the most frequent one. Rare thyroid-related causes of neck pain include hemorrhage within a thyroid nodule as well as Riedel's thyroiditis and suppurative thyroiditis. In the last 30 years, a few cases of a painful variant of Hashimoto's thyroiditis (HT) have been described. Biochemical, ultrasound, and histologic features were clearly suggestive for HT in all of the published cases and definitely ruled out the diagnosis of SAT. While sound descriptions of painful HT are present in the literature, it is important to emphasize that only 20 cases were reported from the year 2000 until now. The condition, however, is clinically relevant because neck pain was reported to be refractory both to steroids and to other analgesic drugs, being thyroidectomy the only effective treatment for pain relief in these patients. This short review analyzes currently available data supporting a role for HT as a rare cause of neck pain.

To analyze three-dimensional (3D) volume and histogram of thyroid gland on neck computed tomography (CT) for patients with Hashimoto's thyroiditis. A total of 121 subjects who underwent neck CT between March 2013 and February 2014 were included in this study. These subjects were divided into the following two groups: 1) control group (n = 76); 2) Hashimoto's thyroiditis group (n = 45). Non-enhanced and contrast-enhanced CT images were obtained. On contrast-enhanced images, the 3D volume of thyroid gland was semi-automatically calculated. On CT histogram, attenuation number, mean, median, standard deviation (SD), and coefficient of variation (CV) of thyroid gland were calculated. These values were compared between the two groups. Total 3D volume of thyroid gland was 14.9 ± 4.8 cm 3 in the control group, which was significantly (p = 0.002) lower than that (19.2 ± 8 cm 3 ) in the Hashimoto's thyroiditis group. On CT histogram, the mean, median, SD, and CV of thyroid gland on non-enhanced images were 95.8, 99.3, 21.7, and 0.226, respectively, in the control group and 72.2, 72.6, 19.6, and 0.28 in the Hashimoto's thyroiditis group (p < 0.05). Histogram parameters on contrast-enhanced images were not significantly (p > 0.05) different. Median at cut-off value of 83 revealed the largest Az value (Az: 0.905; 95% confidence interval: 0.837-0.951; sensitivity: 84.4%; specificity: 85.5%). The Hashimoto's thyroiditis group had larger volume but lower CT attenuation number with more prominent parenchymal heterogeneity of thyroid gland than the control group

On CT histogram, the mean, median, SD, and CV of thyroid gland on non-enhanced images were 95.8, 99.3, 21.7, and 0.226, respectively, in the control group and 72.2, 72.6, 19.6, and 0.28 in the Hashimoto's thyroiditis group (p < 0.05). Histogram parameters on contrast-enhanced images were not significantly (p > 0.05) different. Median at cut-off value of 83 revealed the largest Az value (Az: 0.905; 95% confidence interval: 0.837-0.951; sensitivity: 84.4%; specificity: 85.5%). The Hashimoto's thyroiditis group had larger volume but lower CT attenuation number with more prominent parenchymal heterogeneity of thyroid gland than the control group.

Background: Hashimoto's thyroiditis (HT) has been found to coexist with differentiated thyroid cancer (DTC) in surgical specimens, but an association between the two conditions has been discounted by the medical literature. Therefore, we performed this study to determine any potential relationship between HT and the risk of developing DTC. Methods: We collected data for thyrotropin (TSH), thyroxine (T4), thyroid peroxidase antibody (TPO-Ab) titers, surgical pathology, and weight-based levothyroxine (LT4) replacement dose for patients who were referred for thyroid surgery. Patients with HT at final pathology were studied further. To estimate thyroid function, patients with preoperative hypothyroid HT (Hypo-HT) were divided into three equal groups based on their LT4 replacement: LT4-Low (1.43 μg/kg). A group of preoperatively euthyroid (Euth-HT) patients but with HT by pathology was also studied. All subjects were also grouped based on their TPO-Ab titer in TPO-high (titer >1:1000) or TPO-low/negative (titer thyroid glands (LT4-Low) but not in fully hypothyroid HT (LT4-Mid and LT4-High). High TPO-Ab titers appear to protect against DTC in patients with HT. PMID:24708347

We report a longstanding selective memory deficit in a euthyroid 45-year-old woman who was being treated with levothyroxine for Hashimoto thyroiditis. The patient had complained of memory problems and deterioration of her concentration skills for about 2 years. Her endocrinologist thought that she was depressed. The patient's physical examination was normal. She scored a full 30 points on the Mini-Mental State Examination, but neuropsychological evaluation showed a significant deficit in her verbal memory. Routine blood tests and cerebrospinal fluid analysis showed only antithyroid peroxidase antibodies. Brain magnetic resonance imaging was normal. Electroencephalogram showed scarce intermittent bilateral multifocal theta waves. We increased the patient's daily dose of levothyroxine and started her on dexamethasone therapy. Five months later, we repeated the entire evaluation and found both her cognitive function and her electroencephalogram to be normal. Autoimmune encephalopathy associated with Hashimoto thyroiditis is already known to present with either stroke-like episodes or diffuse progressive deterioration. Our patient shows that the encephalopathy can present as a chronic selective memory deficit that can spare executive functions and short-term memory. This presentation can be missed or mistaken for depression, but can be diagnosed with a detailed neuropsychological evaluation.

98 patients with Graves' disease have been compared to 95 patients with Hashimoto's thyroiditis and to 97 patients with benign thyroid nodules (control group) in order to evaluate the triggering role of major stressors and pregnancy in the occurrence of autoimmune thyroid diseases. A stress factor has been encountered in 11% cases of Graves' disease and in 6% of Hashimoto's and thyroid nodes (chi 2 test, not different). Graves' disease occurred after a pregnancy in 25% of the women in child bearing age versus 10% of the cases of Hashimoto's (p thyroid nodes. The role of stressors, if any, in triggering Graves' disease seems to be weak and dubious compared to the role of pregnancy and post-partum. It is assumed that the decrease of immunosuppressive hormones occurring after stress or delivery could induce a rebound autoimmune reaction responsible for the thyroid disease. In Hashimoto's thyroiditis, stress and pregnancies do not seem to have any triggering role.

The purpose of this study was to investigate the risk factors for central and lateral neck lymph node metastases in papillary thyroid carcinoma (PTC) and multifocal papillary thyroid carcinoma (MPTC), particularly when associated with Hashimoto thyroiditis (HT).A retrospective analysis of 763 consecutive patients who underwent total thyroidectomy with bilateral central neck dissection in the First Affiliated Hospital, College of Medicine, Zhejiang University between October 2011 and October 2014 was conducted. All patients had formal histological diagnoses of HT. Multivariable logistic regression analysis was performed to identify risk factors of neck lymph node metastases.Our study identified 277 PTC patients with HT and showed comparatively low rates of central lymph node metastases (CLNM) compared with the PTC patients without HT (37.2% versus 54.7%, P thyroid peroxidase antibody >140 IU/mL was established as the most sensitive and specific level for the prediction of MPTC based on receiver operating characteristic curve analyses. Thyroid peroxidase antibody, age, tumor size, and multifocality exhibited the ability to predict CLNM in PTC with HT patients with an area under the curve of 81.1% based on a multivariate model.Hashimoto thyroiditis was associated with increased prevalences of multifocality and capsular invasion. In contrast, HT was associated with a reduced risk of CLNM in PTC and MPTC patients, which indicated a potential protective effect. We found that the prognostic prediction model was applicable for predicting multifocality and CLNM in PTC patients with HT.

Radioactive-iodine remnant ablation is an integral part of the papillary thyroid carcinoma (PTC) treatment. Although a minimum dose is usually recommended, there is controversy as to whether the low-dose (1100 MBq) radioactive-iodine remnant ablation is adequate for selected patients. A retrospective cohort study was conducted on 691 patients. Patients with no remnant thyroid on the follow-up whole body scan and low stimulated thyroglobulin (sTg) level (Hashimoto thyroiditis based on histopathology diagnosis (odds ratio [OR] = 3.23; p Hashimoto thyroiditis and elevated sTg are negative predictive factors for successful low-dose radioactive-iodine remnant ablation treatment. An appropriate risk-adjusted approach may improve the efficacy of radioactive-iodine remnant ablation treatment. © 2015 Wiley Periodicals, Inc.

BACKGROUND: The incidence of thyroid cancer (TC) is increasing although explanatory causes are lacking. A link between cancer and inflammation is well documented but unclear for autoimmune thyroid diseases and TC. We aimed to systematically review the association between Hashimoto's thyroiditis (HT......) and papillary, follicular, medullary, anaplastic thyroid carcinoma, and thyroid lymphoma (TL). METHODS: PubMed, OVID Medline, Google Scholar, and the Cochrane Library were searched from 1955 to 2016. The inclusion criteria were age >18 years, ≥20 cases of HT or TC. We collectively examined the incidence of HT...... in TC and of TC in HT. RESULTS: We identified 36 studies (64,628 subjects) published between 1955 and 2016 from 13 countries. We found a relative risk (RR) of HT among papillary thyroid cancer (PTC) of 2.36 [95% confidence intervals (CIs) 1.55-3.29, p

Hashimoto thyroiditis (HT) is an autoimmune thyroid disorder that usually presents as a diffuse, nontender goiter, whereas subacute thyroiditis (SAT) is an uncommon disease that is characterized by tender thyroid enlargement, transient thyrotoxicosis, and an elevated erythrocyte sedimentation rate (ESR). Very rarely, patients with HT can present with painful, tender goiter or fever, a mimic of SAT. We report a case of painful HT in a 68-year-old woman who presented with pain and tenderness in a chronic goiter. Her ESR was definitely elevated and her thyroid laboratory tests suggested subclinical hypothyroidism of autoimmune origin. 99mTc pertechnetate uptake was markedly decreased. Fine needle aspiration biopsy revealed reactive and polymorphous lymphoid cells and occasional epithelial cells with Hürthle cell changes. Her clinical symptoms showed a dramatic response to glucocorticoid treatment. She became hypothyroid finally and is now on levothyroxine therapy. PMID:22570820

The biology of thyroid cancer represents a spectrum of behavior ranging from well-differentiated lesions with an excellent prognosis to anaplastic carcinoma, which is almost fatal. For this reason, it is important that clinicians have methods at their disposal to asses the characteristics of patient's thyroid malignancy. In this work we discuss the behavior of differentiated thyroid cancer in associated diseases of thyroid as: Graves' disease, chronic lymphocytic thyroiditis--Hashimoto and nodular goiter. This is retrospectively reviewing of 50 patients treated for differentiated thyroid carcinoma at Department of surgery, Clinical Centre of Montenegro in Podgorica from 1998 until 2003. We evaluated occurrence, as well as the role of this diseases in patients with thyroid cancer. We found a more favorable course of thyroid cancer in the presence of chronic lymphocytic thyroiditis and nodular goiter, a contrary Graves' disease. In associated diseases of thyroid, a significantly greater proportion of patients with thyroid cancer, have modular goiter.

To report the case of an individual with PHP, Turner syndrome and Hashimoto's thyroiditis. A 16-year-old girl was referred to our hospital with chief complaint of short stature. She presented with round chubby facies, short neck, obesity and short stature. Radiography indicated short metatarsals and metacarpals, which mainly affected the second, third and fourth digits. Biochemistry revealed hyperphosphatemia, increased serum concentrations of parathyroid hormone and thyroid stimulating hormone, elevated levels of follicular-stimulating hormone and prolactin, and increased thyroid peroxidase antibody and thyroglobulin antibody. Radiographic examination revealed delayed bone age and pelvic ultrasonography demonstrated an immature uterus. Karyotype analysis showed 46,X,i(Xq10), while molecular analysis revealed a same sense mutation in exon 5 of GNAS (ATC → ATT, Ile).The specific diagnosis was made of Turner syndrome in the presence of Hashimoto's thyroiditis and PHP. She was treated with calcium supplementation, calcitriol and thyroxine. This is the first case report to describe a combination of Turner syndrome with these other clinical entities, and their co-existence should be considered and further investigated.

In a case of Hashimoto's disease complicated by thyroid gland cancer, the primary site of the cancer was visualized as a cold nodule on Tc-99m pertechnetate scintigraphy, as a warm nodule on Tl-201 early imaging, and as a hot nodule on Tl-201 delayed imaging. Generally, Tl-201 shows markedly diffuse accumulation in the lesions of Hashimoto's disease. The warm nodules observed on early scans suggested similar accumulation at the sites of Hashimoto's disease and thyroid cancer. The hot nodules on delayed imaging may be due to the difference in Tl-201 washout time between the sites of Hashimoto's disease and thyroid cancer. There was markedly increased Tl-201 accumulation in bilateral cervical metastatic lymph nodes on both early and delayed images

An association between Hashimoto thyroiditis and papillary thyroid carcinoma has been postulated for decades. We undertook this study to identify potential precursors of papillary thyroid carcinoma in Hashimoto thyroiditis using a combination of morphologic, immunohistochemical, and molecular techniques. For the study, samples from 59 cases of Hashimoto thyroiditis were stained with antibodies to HBME1 and cytokeratin (CK)19. Tiny HBME1+ and CK19+ atypical cell clusters were identified and analyzed for the BRAF mutation by the colorimetric Mutector assay and allele-specific polymerase chain reaction. HBME1+ and CK19+ atypical cell clusters were identified in 12 (20%) of 59 cases. The minute size (Hashimoto thyroiditis.

Background Pituitary antibodies have been reported with greater frequency in patients with Hashimoto's thyroiditis than in healthy controls, although there is significant variability in the strength of the association and the methodologies used. Methods We designed a nested case–control study to characterize the prevalence of pituitary antibodies at the time of the clinical diagnosis of Hashimoto's thyroiditis, as well as at 2, 5, and 7 years before diagnosis. Active component female service member cases (n=87) and matched female controls (n=107) were selected using the Defense Medical Surveillance System database (DMSSD) between January 1998 and December 2007. Pituitary antibodies were measured by immunofluorescence using human pituitary glands collected at autopsy as the substrate. Results At diagnosis, pituitary antibodies were present in 9% of cases with Hashimoto's (8 of 87) and 3% of controls (3 of 107). When the data were analyzed using a conditional logistic regression model, which takes into account the matching on age and work status, pituitary antibodies increased the odds of having Hashimoto's thyroiditis by sevenfold (95% confidence interval from 1.3 to 40.1, p=0.028), after adjusting for components of the DMSSD-category-termed race and for thyroperoxidase antibodies. Before diagnosis, pituitary antibodies were positive in 3 of the 11 subjects (2 cases and 1 control) at the −2-year time point, and negative in all 11 subjects at the −5- and −7-year time points. Conclusions In summary, using a nested case–control design, we confirm that pituitary antibodies are more common in Hashimoto's thyroiditis and suggest that they appear late during its natural history.

We have previously hypothesized that early miscarriage in women with Hashimoto thyroiditis might be the result of a cross-reactivity process, in which blocking autoantibodies against thyrotropin receptor (TSHr-Ab) antagonize hCG action on its receptor on the corpus luteum. To test this hypothesis from the clinical perspective, we investigated the presence of TSHr-Ab in Hashimoto thyroiditis patients with apparently unexplained, first-trimester recurrent miscarriages compared to that in Hashimoto thyroiditis patients with documented normal fertility. A total of 86 subjects (43 cases and 43 age-matched controls) were finally included in a case-control study. No difference in the prevalence of TSHr-Ab positivity was detected between cases and controls (Fisher's exact test, p value = 1.00). In patients with recurrent miscarriages, TSHr-Ab concentrations did not predict the number of miscarriages (univariate linear regression, p value = 0.08). These results were robust in sensitivity analyses, including only cases with full investigation or those with three or more miscarriages. We conclude that no role could be advocated for TSHr-Ab in the aetiology of recurrent miscarriages in women with Hashimoto thyroiditis.

We aimed to investigate the ovarian function and reserve in euthyroid adolescents (TSH Hashimoto thyroiditis (HT). This case-control study included 30 adolescent girls (mean age 15.1 ± 1.4 years) newly diagnosed as HT with presence of high thyroid antibodies with gland heterogeneity in ultrasound and age-matched 30 healthy female subjects. Anti-ovarian antibody (AOAb), LH/FSH ratio, estradiol, anti-mullerian hormone (AMH), inhibin-B, total testosterone, antral follicle count, ovarian volumes and uterine length were measured. The clinical, laboratory, and ultrasound data of the HT and control groups were compared. There were no significant differences between the girls with HT and healthy controls in relation to LH/FSH ratio, estradiol and inhibin-B levels. AOAb (p = 0.02), AMH (p = 0.007) and total testosterone levels were higher in HT group than the control group (p = 0.03). AOAb level was found to be positively correlated with LH/FSH ratio (p = 0.03), AMH (p = 0.01) and inhibin-B (p thyroiditis had normal ovarian reserve based on measurements of AMH, inhibin B, FSH, LH/FSH ratio, estradiol and antral follicle counts.

Full Text Available Hypothyroidism is a common disorder that confers an increased cardiovascular risk. The most common cause is Hashimoto thyroiditis (HT but it can also be caused by thyroidectomy and radioiodine therapy. The aim of the study is to examine whether there is a relation between the cause of hypothyroidism and cardiovascular risk. Subjects and methods: The study included 20 patients with Hashimoto thyroiditis and hypothyroidism, 20 patients with post-thyroidectomy hypothyroidism, 20 patients with post-radioiodine hypothyroidism, and 20 age and sex matched controls. In all the studied subjects we determined thyroid function tests; TSH and F.T4, thyroid auto-antibodies; anti-TPO and anti-TG antibodies, carotid intima media thickness (CIMT, flow mediated dilation (FMD and serum nitric oxide. Results: CIMT showed a trend to be higher in HT group (0.93 ± 0.08 mm compared to other causes of hypothyroidism (P = 0.090. Multivariate analysis showed that HT is an independent predictor of CIMT (P = 0.015. FMD was significantly lower in HT group (5.74 ± 1.33% compared to post-thyroidectomy (7.16 ± 1.05% (P = 0.001, and post-radioiodine therapy (7.34 ± 1.34% (P = 0.000. Multivariate analysis showed that HT is an independent predictor of FMD (P = 0.000. NO was significantly higher in hypothyroid patients (125.98 ± 5.03 μM/ml compared to controls (39.44 ± 3.63 μM/ml (P = 0.001, both univariate and multivariate analyses showed that NO is an independent predictor of both CIMT and FMD (P = 0.000. Conclusion: To our knowledge, this is the first study to show that Hashimoto thyroiditis is an independent cardiovascular risk factor in clinically hypothyroid patients.

The authors examined 155 autopsy cases of Hashimoto's thyroiditis in the Life Span Study sample including both A-bomb survivors and controls in Hiroshima and Nagasaki (1954 to 1974). Hashimoto's thyroiditis was classified into lymphoid, diffuse and fibrous types and the following results were obtained. No difference existed in the effects of A-bomb radiation in the incidence and ATB. The ratio of males to females did not reveal statistical significance, even though reversed ratio was noted in the high dose group. The variation of thyroid gland weight in T65 dose or by variant showed no significant pattern, even though the smallest average weight was found in the highest radiation exposure group. The complications in the patients with Hashimoto's thyroiditis were noted to have high prevalance of ovarian cancer and low prevalence of stomach cancer and total cancer. Only two patients with Hashimoto's thyroiditis were found to be complicated with thyroid carcinoma. Among collagen diseases, the prevalence of rheumatic fever and rheumatoid arthritis was high as complication. And the prevalence of combined diseases suggested that no late effect of A-bomb radiation existed.

The aim of this study was to evaluate clinical and laboratory findings and determine the prevalence of celiac disease (CD) in children with Hashimoto thyroiditis (HT). The data of a total of 80 patients with positive anti-thyroid antibodies who were aged between 6 and 17.9 years were retrospectively studied. Age, gender, complaints at the time of presentation, family history of thyroid disorders, clinical and laboratory findings were recorded. The levels of thyrotropin, free thyroxin, thyroid autoantibodies (thyroid peroxidase and thyroglobulin antibodies), immunoglobulin A (IgA), anti-tissue transglutaminase antibodies (IgA-tTG), and thyroid ultrasonography findings were enrolled. Eighty patients (65 females (81.2%) and 15 males (18,8%)) were included in the study. Family history of thyroid disease was present in 38 (47.5%) patients. The most common complaints at the time of presentation were goiter (%30) and weight gain (%25). Forty three (53.8%), 23 (28.7%), and 14 (17.5%) patients presented with euthyroidism, subclinical hypothyroidism and obvious hypothyroidism. Thirty seven (46.2%) patients had goiter. IgA-tTG was found to be positive after a diagnosis of HT was made in only one patient (1.25%) and the diagnosis of CD was confirmed when intestinal biopsy of this patient revealed villus atrophy, crypt hyperplasia and increase in the intraepithelial lymphocyte count. In our study, it was found that the most common complaints at presentation in patients with a diagnosis of hashimoto thyroiditis included goiter, weakness and weight gain and the prevalence of celiac diseases was found to be 1.25% (1/80). This study shows that the prevalence of CD in patients with a diagnosis of HT is higher compared to the prevalence in the healthy pediatric population.

Aim—To evaluate the expression of ribosomal cistrons in human thyroid epithelial cells (TECs) of patients with Grave's disease, Hashimoto's thyroiditis and benign and malignant tumours of the thyroid gland. Methods—TEC nucleoli were investigated in fine needle biopsy specimens from 10 controls, 39 patients with Grave's disease, 15 with Hashimoto's thyroiditis, 56 with benign, and 15 with malignant tumours of the thyroid. A one step silver staining method was applied. In most cases serum concentrations of thyroxine and triiodothyronine as well as goitre size were determined. In every case 100 TECs were evaluated for the mean numbers of nucleoli and for the average number of argyrophilic nucleolar organiser regions (AgNORs) per nucleus. Results—NORs were activated in all patients, but not in controls. The numbers of AgNORs in patients with Grave's disease were closely correlated with thyroxine or triiodothyronine, or both, concentrations and with the size of the thyroid. In patients with Hashimoto's thyroiditis about 30% of TECs nucleoli did not contain AgNORs, whereas others were heavily impregnated with silver. Compared with controls and benign tumours, the nucleoli of carcinomatous TECs were larger and irregular in shape. The mean number of AgNORs per nucleus in malignant cells was higher than that in their benign counterparts. Conclusions—The mechanism by which NORs are activated in TECs varies depending on the type of lesion. The higher AgNOR score in TECs from malignant tumours can be used to distinguish them from their benign counterparts. Images PMID:16696083

Computer-aided diagnostic (CAD) techniques aid physicians in better diagnosis of diseases by extracting objective and accurate diagnostic information from medical data. Hashimoto thyroiditis is the most common type of inflammation of the thyroid gland. The inflammation changes the structure of the thyroid tissue, and these changes are reflected as echogenic changes on ultrasound images. In this work, we propose a novel CAD system (a class of systems called ThyroScan) that extracts textural features from a thyroid sonogram and uses them to aid in the detection of Hashimoto thyroiditis. In this paradigm, we extracted grayscale features based on stationary wavelet transform from 232 normal and 294 Hashimoto thyroiditis-affected thyroid ultrasound images obtained from a Polish population. Significant features were selected using a Student t test. The resulting feature vectors were used to build and evaluate the following 4 classifiers using a 10-fold stratified cross-validation technique: support vector machine, decision tree, fuzzy classifier, and K-nearest neighbor. Using 7 significant features that characterized the textural changes in the images, the fuzzy classifier had the highest classification accuracy of 84.6%, sensitivity of 82.8%, specificity of 87.0%, and a positive predictive value of 88.9%. The proposed ThyroScan CAD system uses novel features to noninvasively detect the presence of Hashimoto thyroiditis on ultrasound images. Compared to manual interpretations of ultrasound images, the CAD system offers a more objective interpretation of the nature of the thyroid. The preliminary results presented in this work indicate the possibility of using such a CAD system in a clinical setting after evaluating it with larger databases in multicenter clinical trials.

The aim of this study is to investigate the serum levels of procalcitonin and its association with autoantibodies in patients with euthyroid Hashimoto's thyroiditis. A total of 80 participants were included in the study; 40 of which were newly diagnosed with Hashimoto's thyroiditis, aged over 18, and 40 of which were healthy volunteers. The serum levels of procalcitonin were measured by enzyme-linked immunosorbent assay kit. Thyroid function tests were analyzed in hormone laboratory with Electro-chemiluminescence immunoassay. Hashimoto's thyroiditis patients had higher median procalcitonin levels than those of the control group (34.3 pg/mL vs 27.8 pg/mL respectively; P=.037). Also, male patients had higher median procalcitonin levels as compared to female patients (37 pg/mL vs 27 pg/mL respectively; P=.013). In the Hashimoto's thyroiditis group, procalcitonin level was positively correlated with anti-thyroglobulin and anti-thyroid peroxidase levels (r=.559, Pthyroid peroxidase levels were identified to be an independent predictor in diagnosis of Hashimoto's thyroiditis. The fact that procalcitonin was found to be correlated with thyroid autoantibodies and found to be an independent risk factor for Hashimoto's thyroiditis in the regression analysis in the framework of this study urges us to think that procalcitonin may be associated with the autoimmunity. © 2017 Wiley Periodicals, Inc.

The aim of the study was to analyze the sonographic features of nodular Hashimoto thyroiditis (HT) in patients with diffuse background thyroiditis and normal background thyroid parenchyma. Eighty-six patients who had fine-needle aspiration biopsy of 100 thyroid nodules confirmed to be HT and a thyroid ultrasound within 1 year of the biopsy were included in the study. Retrospective analysis of several sonographic features of each nodule was then performed. The mean age of patients with nodular HT was 53 years, 84% of which were female. Nodular HT occurred in a background of diffuse thyroiditis in 85% and in a homogeneous normal background in 15%. Ninety-three percent of nodules were completely solid and 7% of nodules were cystic and solid. Although the sonographic appearance of nodular HT was variable, the most common appearance was a solid (93/100) and hypoechoic nodule (44/100) with a thin hypoechoic halo (42/100) without calcifications (96/100). On color Doppler, 17% of nodules showed peripheral hypervascularity, 14% of nodules were diffusely hypervascular, 34% were iso vascular, 32% were hypovascular, and 3% were avascular. The sonographic appearance of nodular HT was not significantly different in patients with diffuse background thyroiditis compared with those without background thyroiditis. The sonographic appearance of nodular HT is variable, but the most common appearance is a solid sharply circumscribed hypoechoic nodule with thin hypoechoic halo without calcification. There was no significant difference in the appearance of nodular HT in patients with diffuse background thyroiditis compared with patients with normal background thyroid parenchyma.

Hashimoto thyroiditis (HT), now considered the most common autoimmune disease, was described over a century ago as a pronounced lymphoid goiter affecting predominantly women. In addition to this classic form, several other clinico-pathologic entities are now included under the term HT: fibrous variant, IgG4-related variant, juvenile form, Hashitoxicosis, and painless thyroiditis (sporadic or post-partum). All forms are characterized pathologically by the infiltration of hematopoietic mononuclear cells, mainly lymphocytes, in the interstitium among the thyroid follicles, although specific features can be recognized in each variant. Thyroid cells undergo atrophy or transform into a bolder type of follicular cell rich in mitochondria called Hürthle cell. Most HT forms ultimately evolve into hypothyroidism, although at presentation patients can be euthyroid or even hyperthyroid. The diagnosis of HT relies on the demonstration of circulating antibodies to thyroid antigens (mainly thyroperoxidase and thyroglobulin) and reduced echogenicity on thyroid sonogram in a patient with proper clinical features. The treatment remains symptomatic and based on the administration of synthetic thyroid hormones to correct the hypothyroidism as needed. Surgery is performed when the goiter is large enough to cause significant compression of the surrounding cervical structures, or when some areas of the thyroid gland mimic the features of a nodule whose cytology cannot be ascertained as benign. HT remains a complex and ever expanding disease of unknown pathogenesis that awaits prevention or novel forms of treatment. Copyright © 2014 Elsevier B.V. All rights reserved.

Introduction Different types of thyroiditis may share some parallel clinical and biochemical features. Timely intervention can significantly reduce morbidity and mortality. Aim Aim of this study is to find the frequency of various thyroiditis, study the cytomorphological features and correlate with clinical findings including radiological findings, thyroid function test, and anti-thyroid peroxidase antibodies (Anti-TPO antibodies). Materials and Methods The study included consecutive 110 cases of thyroiditis. Detailed cytomorphological features were studied and correlated with ultrasonography findings, thyroid function test, anti-thyroid peroxidase antibodies (anti-TPO) and histopathological features where thyroidectomy specimens were received for histopathological examination. Results The majority were Hashimoto's thyroiditis (n = 100) and females (n = 103). Other forms of thyroiditis were Hashimoto's thyroiditis with colloid goiter (n = 5), De Quervain's thyroiditis (n = 3), and one case each of postpartum thyroiditis and Hashimoto's thyroiditis with associated malignancy. The majority of patients were in the age group of 21–40 (n = 70) and the majority (n = 73) had diffuse enlargement of thyroid. The majority of patients were hypothyroid (n = 52). The serum anti-TPO antibodies were elevated in 47 patients out of 71 patients. In the 48 patients who underwent ultrasonography, 38 were diagnosed as having thyroiditis. The most consistent cytomorphological features seen in fine-needle aspiration smears of Hashimoto's thyroiditis were increased background lymphocytes, lymphocytic infiltration of thyroid follicular cell clusters, and Hurthle cells. Conclusion The diagnostic cytological features in Hashimoto's thyroiditis are increased background lymphocytes, lymphocytic infiltration of thyroid follicular cell clusters, and Hurthle cells. FNAC remains the “Gold Standard” for diagnosing Hashimoto's thyroiditis. Clinical history, thyroid function, and biochemical

Hashimoto thyroiditis (HT) is the most common pediatric autoimmune endocrine disorder. It results in autoimmune-mediated thyroid gland destruction and is an organ-specific, typical autoimmune disease. The presence of antithyroid antibodies and the typical pattern on ultrasonography indicate the diagnosis. It is also frequently seen together with other autoimmune disorders including type 1 insulin-dependent diabetes, celiac disease, alopecia and vitiligo. Autoimmune hepatitis (AIH) is a chronic type of liver injury with an immune etiology that can frequently cause end-stage liver disease if left untreated. Autoimmune hepatitis patients may present with hepatitis, and the laboratory tests in the absence of other etiology usually reveal a positive immune serology together with elevated immunoglobulins and abnormal liver histology. It is interesting that HT and AIH are rarely seen together although both have an autoimmune etiology. 14-year-old male who was being followed-up for vitiligo presented with symptoms of a swelling at the neck and fatigue. He was diagnosed with HT after the tests and the liver enzymes were found to be high. The patient was also diagnosed with AIH after tests revealed that the liver enzyme elevation had continued for longer than six months. The thyroid functions and liver enzymes returned to normal and the symptoms decreased after sodium L-thyroxine replacement together with steroid and azathioprine treatment. We present this case as we believe it is the first pediatric patient diagnosed with HT, AIH and vitiligo.

The aim of this study was to analyze the presence of malignancy in patients with Hashimoto's thyroiditis and to investigate the reliability of preoperative fine-needle aspiration biopsy (FNAB). The retrospective study included 44 patients who were operated on for nodular goiter between December 2010 and October 2011. The patients underwent thyroidectomy following a cytologic analysis plus FNAB. Hashimoto's thyroiditis was confirmed on histopathology in all patients. FNAB results were defined as benign in 14 (31.8%), suspicion for malignancy in 17 (38.6%), malignant in 9 (20.5%), and inadequate in 4 (9.1%). Following the thyroidectomy, presence of papillary thyroid carcinoma and follicular variant of papillary thyroid carcinoma were detected in 10 patients (22.7%) and 1 (2.3%) patient, respectively. The FNAB results were interpreted in terms of malignancy, which revealed the sensitivity as 80%; specificity, 40%; false positives, 69.2%; false negatives, 14.3%; positive predictive value, 31.8%; negative predictive value, 85.7%; and diagnostic accuracy, 50%. The coexistence of Hashimoto's thyroiditis with papillary thyroid carcinoma is quite common. The FNAB results for such cases are hard to evaluate, and they are likely to increase the number of false positives.

2008-09-01

Presence of autoantibodies to alfa-fodrin was investigated in patients with Sjögren's syndrome (n = 61), Hashimoto thyroiditis (n = 27), Sjögren's syndrome associated with Hashimoto thyroiditis (n = 31) and in healthy persons (n = 77). In each group, level of alfa-fodrin antibodies was higher than in the controls. There was no significant difference in their presence either between patients with Hashimoto thyroiditis with or without Sjögren's syndrome, or-in IgA isotype-between Sjögren's and Hashimoto thyroiditis patients. Correlation was found between the level of IgG alfa-fodrin and anti-thyroglobulin antibodies. Based on these findings, fodrin can be associated with both endocrine and exocrine glandular secretion. Antibodies to alfa-fodrin might have a role in the pathogenesis of Hashimoto thyroiditis concerning the "final common effectory pathway", secretion. Alfa-fodrin antibodies can be good markers of secretory disorders. Assessment of these autoantibodies might help the diagnosis and follow-up of patients with impaired secretory capability of not only autoimmune origin.

To investigate the thyrocyte apoptosis, the expression of Bcl-2, Bax and the relationship between apoptosis and the pathogenesis in Hashimoto's thyroiditis (HT), 41 HT thyroid and 10 normal thyroid specimens were selected. The level of apoptosis was detected by TUNEL methods. The expression and distribution of Bcl-2 and Bax were detected using immunohistochemical methods and analyzed by Mias99 pathological image system. Immunohistochemical staining was carried out using S-P kit. The Result showed that an increased level of apoptosis was observed in Hashimoto's glands. The apoptosis mainly distributed in thyroid follicles destruction area. This was associated with increased Bax expression. The strongly positive Bcl-2 staining was observed in the thyrocyte of intact thyroid follicles. The ratios of positive granule area and total light density of Bcl-2 to those of Bax in HT thyroid follicle area were lower than those in normal thyroid. The apoptosis of thyrocyte induced by dysregulation of Bcl-2 and Bax may be involved in the pathogeneses of HT

Autoimmune thyroid disease (AITD), also known as Hashimoto thyroiditis (HT), is a degenerative inflammatory disease with high prevalence among women and has been associated with fibromyalgia and widespread chronic pain. The goal was to determine the frequency of temporomandibular disorders (TMD) in patients with HT. In all, 119 women (age 19-60 years) were divided into a study (52 women diagnosed with HT) and a control (67 healthy individuals, of which 15 were excluded) group. Serum concentrations of thyroid-stimulating hormone (TSH), free triiodothyronine (fT3), free thyroxine (fT4), anti-thyroglobulin (Tg) and anti-thyroid peroxidase (TPO) antibody levels were measured. The temporomandibular jaw and muscles were examined using the German Society of Functional Diagnostics and Therapy guidelines. The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) was used to assess TMD. Standardized questionnaires, incorporating epidemiological criteria, state and treatment of the thyroid disease, Helkimo Index (HI), and Fonseca Anamnestic Index (FAI), were filled out by all patients. The two groups did not differ in terms of demographic parameters or mandibular jaw mobility. Significantly higher levels of anti-TPO and anti-Tg were attested in all subjects of the HT group. Markedly elevated prevalence of TMD was found in the HT group. Muscle pain and stiffness were found in 45 (86.5%) subjects of the HT group (p < 0.001), of whom 33 (63.4%) also had disc displacement with reposition (p < 0.001). Whereas 50% of the control group showed no TMD symptoms, all subjects in the HT group had symptoms. A significantly elevated prevalence of TMD was found in patients with HT. Thus, patients with TMD who do not respond to therapy should be referred for thyroid diagnostic workup.

Full Text Available Retroperitoneal fibrosis (RPF is a rare disease characterized by the presence of fibroinflammatory tissue around the abdominal aorta and ureteral entrapment in most cases. Idiopathic RPF is frequently reported in association with autoimmune diseases; however, there have been few reports of idiopathic RPF associated with Hashimoto's thyroiditis. Here, we report a case of idiopathic RPF with Hashimoto's thyroiditis in a patient with a single functioning kidney, which was successfully treated by corticosteroid therapy and transient intraureteral stent insertion with a double-J catheter.

Periodontitis is a multifactorial disease with microbial dental plaque as the initiator of periodontal disease. However, the manifestation and progression of the disease is influenced by a wide variety of determinants and factors. The strongest type of causal relationship is the association of systemic and periodontal disease. Hashimoto's thyroiditis has also been considered as one of the causes of periodontal disease. This clinical case report highlights the impact of Hashimoto's thyroiditis on the outcome of periodontal therapy.

Oncocytic cells (OCs) are characterized by an accumulation of mitochondria and their occurrence in the thyroid gland of patients with Hashimoto thyroiditis (HT) is well known. However, their properties and functional relevance are poorly understood. We investigated OC lesions (n=212) in the thyroid of 12 HT patients. Loss of complex I protein was observed in oncocytic lesions of each of the patients. In addition to isolated complex I deficiency, 25% of oncocytic lesions showed combined deficiency of complex I and IV. Thus, we demonstrate for the first time a defect of respiratory chain complex I in OCs of HT patients. Copyright © 2015 Elsevier B.V. and Mitochondria Research Society. All rights reserved.

Adult-onset metachromatic leukodystrophy (MLD) often shows schizophrenia- or encephalopathy-like symptoms at an early stage, such as behavioural abnormalities, cognitive impairment, mood disorders and hallucinations. The authors report the case of an adult woman with MLD who had been given antipsychotic medication for schizophrenia. In the differential diagnosis, screening of auto-antibodies was important for ruling out other encephalopathies as she had a euthyroid Hashimoto thyroiditis. Diagnosis was based the results of MRI, nerve conduction velocity, sensory evoked potential, motor evoked potential, lysosomal enzyme activity and gene analysis studies. Brain MRI showed diffuse demyelination spreading from the deep white matter to subcortical area as high signals at the edges of these lesions in diffusion and apparent diffusion coefficient-map images with the U-fibres conserved. The authors diagnosed adult-onset MLD coexisting with euthyroid autoimmune Hashimoto thyroiditis. PMID:22798296

One of the most common causes of hypothyroidism is Hashimoto's Thyroiditis (HT). Early detection of dry mouth is critical in preserving and promoting systemic and oral health. In this study we have assessed, for the first time, salivary function and xerostomia in HT patients who have not been involved with Sjögren's syndrome. HT was diagnosed in 40 patients based on clinical findings and positive anti-thyroid peroxidase antibodies (anti-TPO). Controls, matched by sex, age and body mass index (BMI), and with no history of thyroid disease, were selected. A questionnaire was used for diagnosis of xerostomia. Saliva samples were taken between 8 a.m. and 9 a.m., and at least 2 hours after the last intake of food or drink. The flow rate was calculated in milliliters per minute. Xerostomia was significantly higher in patients with HT. Unstimulated salivary flow rate was significantly lower in the HT group. Stimulated salivary flow rate was lower in HT group, but the difference was not significant. The patients with HT experienced xerostomia, and their salivary flow rate was diminished. Spitting the saliva then assessing salivary flow rate based on milliliter per minute is non-invasive, fast, and simple for chair-side diagnosis of dry mouth. Autoimmune diseases can be accompanied by salivary gland dysfunction. This may be due to the effect of cytokines in the autoimmune process or because of thyroid hormone dysfunctions.

Hashimoto's thyroiditis is an autoimmune disorder and the most common cause of hypothyroidism. The use of Nigella sativa, a potent herbal medicine, continues to increase worldwide as an alternative treatment of several chronic diseases including hyperlipidemia, hypertension and type 2 diabetes mellitus (T2DM). The aim of the current study was to evaluate the effects of Nigella sativa on thyroid function, serum Vascular Endothelial Growth Factor (VEGF) - 1, Nesfatin-1 and anthropometric features in patients with Hashimoto's thyroiditis. Forty patients with Hashimoto's thyroiditis, aged between 22 and 50 years old, participated in the trial and were randomly allocated into two groups of intervention and control receiving powdered Nigella sativa or placebo daily for 8 weeks. Changes in anthropometric variables, dietary intakes, thyroid status, serum VEGF and Nesfatin-1 concentrations after 8 weeks were measured. Treatment with Nigella sativa significantly reduced body weight and body mass index (BMI). Serum concentrations of thyroid stimulating hormone (TSH) and anti-thyroid peroxidase (anti-TPO) antibodies decreased while serum T3 concentrations increased in Nigella sativa-treated group after 8 weeks. There was a significant reduction in serum VEGF concentrations in intervention group. None of these changes had been observed in placebo treated group. In stepwise multiple regression model, changes in waist to hip ratio (WHR) and thyroid hormones were significant predictors of changes in serum VEGF and Nesgfatin-1 values in Nigella sativa treated group (P thyroid status and anthropometric variables in patients with Hashimoto's thyroiditis. Moreover, Nigella sativa significantly reduced serum VEGF concentrations in these patients. Considering observed health- promoting effect of this medicinal plant in ameliorating the disease severity, it can be regarded as a useful therapeutic approach in management of Hashimoto's thyroiditis.

Aim: The effect of an iodine prophylaxis on the induction of Hashimoto's thyroiditis as well as the influence of various therapeutic approaches on the course of antithyroglobulin (TgAb) and antiperoxidase (TPOAb) antibodies in manifest diseases are evaluated. Method: A collective of 375 euthyroid subjects without relevant goiter received daily doses of 200 micrograms iodide, weekly doses of 1.53 milligrams iodide, or no medication. A second group of 377 patients suffering from Hashimoto's thyroiditis was treated with a non-suppressive hormone medication, a suppressive hormone administration, a combination of a non-suppressive hormone therapy with low dose iodide (50-150 micrograms/day), mere iodide in doses of 200 micrograms/day, or received no therapy. The mean observation period in these two groups was 860 and 848 days, respectively. Results: There was no significant increase of the antibody levels in the subgroup with 200 micrograms iodide/day and in the non-treated subjects of the first collective. However, the group that received 1.53 milligrams iodide/week presented a distinct increase of the TgAb as well as the TPOAb, and the incidence of Hashimoto's thyroiditis was 4-fold higher than in the two other subgroups. The patients of the second collective revealed a sinificant decrease of the TgAb in the subgroups treated with up to 200 micrograms iodide/day, while the reduction of the TPOAb depended on the thyrotropin level and was most significant in the suppressed group (p<0.0001). Conclusion: To lower the incidence of autoimmune thyroid diseases in predisposed subjects, a daily iodine supplementation seems to be superior to high-dose weekly administrations. A hormone therapy combined with a daily, low-dose iodine medication is able to reduce the TgAb and the TPOAb levels even in patients with Hashimoto's thyroidits. (orig.)

Hashimoto's thyroiditis was recently divided into IgG4-plasma cell-rich and IgG4-plasma cell-poor subtypes. The former, also known as IgG4 thyroiditis, is associated with clinical, serological, sonographic and morphological features that are distinctive from those of the non-IgG4 subgroup. We describe an interesting case of IgG4-positive mucosa-associated lymphoid tissue (MALT) lymphoma arising in a background of IgG4 thyroiditis. The thyroid gland showed typical features of IgG4 thyroiditis, including characteristic patterns of fibrosis. A dense lymphoplasmacytic infiltrate diffusely involved the entire gland without formation of a destructive tumour mass. Lymphoepithelial lesions were prominent. There were abundant IgG4-positive plasma cells, with the IgG4/IgG ratio exceeding 40%. The IgG4-positive plasma cells were monotypic for kappa light chain, and there was monoclonal IGH rearrangement. Fluorescence in-situ hybridization revealed IGH translocation without translocation of MALT1, bcl-10, or FOXP1. This represents the first case of IgG4-producing MALT lymphoma associated with IgG4 thyroiditis. IGH translocation with an unknown partner gene was identified. We suggest the performance of serum and immunohistochemical investigations for IgG and IgG4 in all cases of Hashimoto's thyroiditis to diagnose IgG4 thyroiditis. In addition, clonality assays and light chain studies are useful to exclude a low-grade lymphoma arising in this context. © 2015 John Wiley & Sons Ltd.

Hashimoto's encephalopathy : epidemiology, pathogenesis and management.

Hashimoto's encephalopathy is a term used to describe an encephalopathy of presumed autoimmune origin characterised by high titres of antithyroid peroxidase antibodies. In a similar fashion to autoimmune thyroid disease, Hashimoto's encephalopathy is more common in women than in men. It has been reported in paediatric, adult and elderly populations throughout the world. The clinical presentation may involve a relapsing and remitting course and include seizures, stroke-like episodes, cognitive decline, neuropsychiatric symptoms and myoclonus. Thyroid function is usually clinically and biochemically normal.Hashimoto's encephalopathy appears to be a rare disorder, but, as it is responsive to treatment with corticosteroids, it must be considered in cases of 'investigation negative encephalopathies'. Diagnosis is made in the first instance by excluding other toxic, metabolic and infectious causes of encephalopathy with neuroimaging and CSF examination. Neuroimaging findings are often not helpful in clarifying the diagnosis. Common differential diagnoses when these conditions are excluded are Creutzfeldt-Jakob disease, rapidly progressive dementias, and paraneoplastic and nonparaneoplastic limbic encephalitis. In the context of the typical clinical picture, high titres of antithyroid antibodies, in particular antithyroid peroxidase antibodies, are diagnostic. These antibodies, however, can be detected in elevated titres in the healthy general population. Treatment with corticosteroids is almost always successful, although relapse may occur if this treatment is ceased abruptly. Other forms of immunomodulation, such as intravenous immune-globulin and plasma exchange, may also be effective. Despite the link to autoimmune thyroid disease, the aetiology of Hashimoto's encephalopathy is unknown. It is likely that antithyroid antibodies are not pathogenic, but titres can be a marker of treatment response. Pathological findings can suggest an inflammatory process, but features

Abnormally elevated serum T3 concentrations measured by RIA were observed in 19 clinically euthyroid or hypothyroid mongrel dogs. The serum T4 concentrations in these sera were low, normal, or high. Measurement of the intensity of thyroid hormone binding to serum proteins was determined by equilibrium dialysis. A marked decrease in the percent free T3 was observed in these abnormal sera. Polyacrylamide gel electrophoresis, pH 7.4, of normal dog serum enriched with tracer /sup 125/I-labeled thyroid hormones demonstrated binding of (/sup 125/I)T4 to transthyretin, thyroid hormone-binding globulin, and albumin and of (/sup 125/I)T3 primarily to thyroid hormone-binding globulin. In all abnormal sera, polyacrylamide gel electrophoresis demonstrated strikingly higher binding of T3 to immunoglobulin (Ig). Eleven of 16 abnormal sera had minimal to moderate binding of T4 to Ig. The percent free T4 was lower only in dogs whose sera demonstrated markedly increased binding of T4 to Ig. All abnormal sera tested had positive antithyroglobulin antibodies, consistent with the diagnosis of autoimmune lymphocytic thyroiditis. As in humans, antibodies to thyroid hormones in dogs are more common in the presence of Hashimoto's thyroiditis and should be considered when elevated serum thyroid hormone concentrations are observed in the absence of clinical thyrotoxicosis. When an antibody to only one thyroid hormone is present, a marked discrepancy in the serum concentrations of T3 and T4 will be observed.

function at the moment of diagnosing Hashimoto's thyroiditis. METHODS: a descriptive cross-sectional study was conducted in 41 patients with initial diagnosis of Hashimoto's thyroiditis during 2007. They were surveyed and they underwent a thyroid medical examination. The thyroid stimulating hormone dosage and the total thyroxin were determined. The data were analyzed by using the percentage methods, and they were exposed in tables. RESULTS: a predominance of the female sex (78 % was observed. According to age and sex, the most frequent group was the group of females aged 50-59 with 29.26 %. 60.97 % of the patients had family pathological history of thyroid disease. All the patients presented goiter and the grade II was the most common, with 60.97 %. 58.53 % of the patients were functionally euthyroideal. CONCLUSIONS: Hashimoto's thyroiditis was more frequent among females and in the fifth decade of life. The presence of personal pathological history was very usual and all the patients had goiter on the diagnosis. The grade II goiter was the most observed. Most of the patients had a normal thyroid function.

Abstract An association between Helicobacter pylori (H pylori) infection as environmental risk factors for Hashimoto thyroiditis (HT) has been reported. We investigated this hypothesis in women in which HT is more common. Serum immunoglobulin G antibodies against H pylori (enzyme-linked immunosorbent assay), CagA protein (Western blot assay), circulating antibodies to thyroid antigens, mainly thyroperoxidase (TPOAbs) and thyroglobulin (TgAbs), were tested in 101 females with HT and 111 non-HT control women without a history of autoimmune disease. Thyroid function, socioeconomic status at childhood, and family history of thyroid malfunction were also studied. Forty-seven HT women (46.5%) tested seropositive for H pylori versus 48 controls (43.2%; P = 0.63). The prevalence of anti-CagA antibodies was 21.3% in HT-infected patients and 31.2% in infected controls (P = 0.352). Women with HT were older than the controls at a significance level of 0.03, and higher prevalence of hypothyroidism (69% vs 13.5%, respectively) and family history of thyroid malfunction (59% vs 34%, respectively) (P thyroid malfunction was independently associated with an increased risk of HT (odds ratio 3.39, 95% confidence interval 1.86–6.18, P thyroid malfunction is a risk factor for HT.

Objective: To determine the serum autoantibodies contents during different clinical stages in patients with Hashimoto thyroiditis. Methods: Serum TGA and TPOAb were detected with chemiluminescence enzyme immunoassay (ECLEIA) and RIA simultaneously in 125 patients with Hashimoto thyroiditis. Results: HT with hyperthyroidism (12 cases) TGA: ECLEIA, (621 + 245 ) IU/ml, positive rate: 83.3%, RIA:66.7%, TPOAb: ECLEIA (452 ± 203) IU/ml, positive rates: 100%, RIA:75.0%, HT with hypothyroidism (50 cases): TGA: ECLEIA ( 1152 + 420) IU/ml. Positive Rates: 94.0%, RIA: 88.0%, TPOAb: (482 + 302) IU/ml. Positive Rates: 96.0%, RIA:90.9%; HT with normal thyroid function (63 cases): TGA: ECLEIA (230 ± 186) IU/ml. Positive Rates: 58.7%, RIA:38.1%, TPOAb:(302 ± 201)IU/ml. Positive Rates: 92.1%, RIA: 63.5%. Conclusion: Measurement of TGA and TPOAb with ECLEIA is much more sensitive than that with the conventional RIA. (authors)

Immunoglobulin G4-related disease (IgG4-RD) is an emerging clinicopathologic entity characterized by both IgG4+ plasma cell infiltration and fibrosis in one or more organs, prototypically pancreas or salivary/lacrimal glands. IgG4-RD in the thyroid (IgG4-RTD) is an area of active study, and the relationship between IgG4-RTD and Hashimoto thyroiditis is not fully delineated due to their overlapping histologic features. Retrospective review was performed of all thyroidectomy cases demonstrating lymphocytic inflammation at a single institution over a 4-year period. Approximately half (23/38) of patients had a clinical diagnosis of Hashimoto thyroiditis (HT). Nine of the 38 patients had increased absolute and relative numbers of IgG4+ plasma cells. Patients with a clinical diagnosis of HT had increased lymphoplasmacytic inflammation, but the relative proportion of IgG4+ plasma cells was not increased compared to patients without HT. There was no correlation between IgG4 levels and the amount of fibrosis in patients with or without HT. Patients identified as having the fibrosing variant of HT were not more likely to have increased levels of IgG4+ plasma cells than those without. There is significant morphologic and immunohistochemical overlap between HT and IgG4-RTD. Future studies to identify specific characteristics of IgG4-RTD involving the thyroid are necessary to accurately define this entity.

Ultrastructural findings in two cases of Hashimoto's disease and two cases of focal lymphocytic thyroiditis are reported. Stimulated thyrocytes, oncocytes and degenerating thyrocytes were observed in all cases. Multinucleated thyrocytes and epithelial pseudogiant cells were identified in Hashimoto's disease only. Infiltrating lymphocytes, plasma cells, monocytes and macrophages were present in all cases. The ultrastructure of germinal centres was similar to that seen in lymphatic organs. Giant cells of both intra- and extrafollicular localization were seen in Hashimoto's disease. Most of the giant cells were macrophage-derived. Two different ways of giant cell formation were identified: besides the familiar dissolution of plasma membranes of adjacent macrophages, another mechanism of fusion was observed. At sites of contact, peculiar membrane structures were developed and disintegration of plasma membranes occurred in parts adjacent to these structures. These are not identical to desmosomes and are different from Langerhans' granules. They probably represent special organelles for the initiation of cellular fusion.

Full Text Available Diffuse sclerosing papillary thyroid carcinoma (DSPTC is a relatively rare variant of papillary thyroid carcinoma with distinct histological features, radiological characteristics, and biological aggressiveness. Compared with conventional papillary thyroid carcinoma, DSPTC is characterized by scattered microscopic tumor islands, diffuse fibrosis, calcification, and abundant lymphocytic aggregation. A preoperative diagnosis is challenging in the absence of nodules and scanty fine needle aspiration cytology samples. We describe a unique DSPTC patient, an 18-year-old woman who presented with a neck mass that grew slowly for 2 years. The palpable neck mass was nontender, well defined, firm, and unmovable. Laboratory studies showed normal thyroid function and positive autoimmune markers: antithyroglobulin antibody = 1:1600 and antimicrosomal antibody = 1:1600. A neck ultrasound showed diffusely prominent microcalcifications with one small vague nodule. Hashimoto's thyroiditis with an accompanying malignancy was suspected. Based on the result of intraoperative pathology reports, the patient was given a total thyroidectomy. Lymph node dissection and histological analysis revealed bilateral DSPTC in addition to lymphocytic thyroiditis in nonmalignant areas of the thyroid. Clinical and histological diagnostic challenges usually occur when DSPTC presents with a diffuse thyroid enlargement, dispersed microscopic tumor islands (frequently without mass formation, extensive fibrosis, and abundant lymphocytic infiltration mimicking thyroiditis.

The relationship between thyroid-stimulating immunoglobulins, measured by both radioreceptor assay and adenylate cyclase stimulation, and the HLA alleles was studied in 41 patients with Hashimoto's thyroiditis. TSH binding-inhibiting immunoglobulins (TBII) were detected in 9 (22%) patients, and human thyroid adenylate cyclase-stimulating immunoglobulins (HTACS) were found in 21 (51%) patients. Only 2 patients were positive in both assays, and an inverse relationship was observed between TBII and HTACS. In the 21 HTACS-positive patients, HLA-Dw5 was found in 1 subject, compared to 8 of the 20 HTACS-negative patients (P < 0.01), while 4 of the 9 TBII-positive patients had HLA-Dw5 compared to 5 of the 32 TBII-negative subjects (P = 0.09).No significant relations were observed between the presence of HTACS or TBII and HLA-Dw3 or HLA-B8. It is concluded that TBII and HTACS are produced independently in Hashimoto's thyroiditis, and that the production of these autoantibodies seems to be related to the HLA-D region in this disease

Full Text Available Both severe thyrotoxicosis and hypothyroidism may affect brain function and cause a change in consciousness, as seen with a thyroid storm or myxedema coma. However, encephalopathy may also develop in patients with autoimmune thyroid diseases independent of actual thyroid function level, and this is known as Hashimoto's encephalopathy. Although most patients are found to have Hashimoto's thyroiditis, less frequently they have Graves' disease. Clinical manifestations include epilepsy, disturbance of consciousness, cognitive impairment, memory loss, myoclonus, hallucinations, stroke-like episodes, tremor, involuntary movements, language impairment, and gait impairment. Hashimoto's encephalopathy is a relatively rare disease. As a good response can be obtained with corticosteroid therapy, early diagnosis and treatment is very beneficial for patients. Here we report three patients with Hashimoto's encephalopathy with typical manifestations of hallucinations that were associated with hypothyroidism, hyperthyroidism, and euthyroid status, respectively. They all showed a dramatic response to methylprednisolone pulse therapy.

Hashimoto thyroiditis (chronic autoimmune thyroiditis) is the most common form of thyroiditis in childhood. Previous studies have found autonomic dysfunction of varying magnitude in patients with autoimmune diseases, which is considered a cardiovascular risk factor. We aimed to evaluate the heart rate variability (HRV), a measure of cardiac autonomic modulation, in children with euthyroid Hashimoto thyroiditis (eHT). The study included 32 patients with eHT (27 girls and 5 boys; mean age 11 ± 4.1 years, range 8-16; body mass index 0.47 ± 0.69 kg/m(2)), as judged by normal or minimally elevated serum TSH levels (normal range: 0.34-5.6 mIU/l) and normal levels of free thyroid hormones (FT4 and FT3) and 38 euthyroid age-matched controls. Patients with eHT and control subjects underwent physical examination and 24-hour ambulatory ECG monitoring. Time-domain parameters of HRV were evaluated for cardiac autonomic functions. Children with eHT displayed significantly lower values of time-domain parameters of SDANN (standard deviation of the averages of NN intervals), RMSSD (square root of the mean of the sum of the squares of differences between adjacent NN intervals), NN50 counts (number of pairs of adjacent NN intervals differing by more than 50 ms) and PNN50 (NN50 count divided by the total number of all NN intervals) for each 5-min interval, compared to healthy controls (p < 0.05 for each), indicating the decreased beat-to-beat variation of heart rate. In conclusion, eHT is associated with disturbed autonomic regulation of heart rate. Hence, the children with eHT are at higher risk for developing cardiovascular diseases.

Thyrotropin-secreting adenoma (TSHoma) is rare, diagnosis and treatment are often delayed if the condition coexists with Hashimoto thyroiditis. The enlarged pituitary adenoma may eventually induce panhypopituitarism, infertility, or the compression of optic nerves and optic chiasma. This patient was a 36-year-old man who had been referred to the pituitary disease multidisciplinary team (MDT) of the West China Hospital, due to infertility. Examinations revealed pituitary thyrotropin-secreting macroadenoma. We conducted trans-sphenoidal surgery. Human chorionic gonadotropin (HCG) and human menopausal gonadotropin (HMG) were used for reproductive reconstruction after surgery. This patient successfully fathered a child. To date, the multidisciplinary team treatment of TSHoma was rare, TSHomas are often misdiagnosed as macroadenomas, because the clinical features are varied and it often takes a long time to be diagnosed. So the purpose of this case report is to attract attention to the manifestation of increased thyroid stimulating hormone (TSH) concentration and discuss MDT treatment for TSH-secreting adenoma.

The objective of the study was to evaluate whether texture analysis using histogram and gray level co-occurrence matrix (GLCM) parameters can help clinicians diagnose lymphocytic thyroiditis (LT) and differentiate LT according to pathologic grade. The background thyroid pathology of 441 patients was classified into no evidence of LT, chronic LT (CLT), and Hashimoto's thyroiditis (HT). Histogram and GLCM parameters were extracted from the regions of interest on ultrasound. The diagnostic performances of the parameters for diagnosing and differentiating LT were calculated. Of the histogram and GLCM parameters, the mean on histogram had the highest Az (0.63) and VUS (0.303). As the degrees of LT increased, the mean decreased and the standard deviation and entropy increased. The mean on histogram from gray-scale ultrasound showed the best diagnostic performance as a single parameter in differentiating LT according to pathologic grade as well as in diagnosing LT.

Calder, Elizabeth A.; McLeman, Dena; Irvine, W. J.

1973-01-01

Lymphocytes from healthy donors were incubated with serum samples from nine patients with Hashimoto thyroiditis and subsequently shown to be cytotoxic to chicken red blood cells (Ch. RBC) coated with thyroglobulin. Target cell death was estimated using a standard 51Cr release assay system. Lymphocytes pre-incubated with Hashimoto serum caused a mean% 51Cr release of 13·11±2·83 (SEM) from thyroglobulin-coated Ch. RBC and a mean% 51Cr release of 1·22±0·65 from uncoated Ch. RBC. Untreated lymphocytes caused no significant isotope release from either uncoated or thyroglobulin coated target cells. PMID:4800956

Hashimoto's thyroiditis (HT) and Graves' disease (GD) are two opposite poles in the spectrum of autoimmune thyroid disease. On one extreme, HT or Chronic Lymphocytic thyroiditis (CLT) courses, as its name implies, with lymphocytic infiltrates replacing thyroid follicles, resulting in a loss of hormone-producing cells and, thus, primary hypothyroidism. On the other extreme, GD is characterized by primary hyperthyroidism due to stimulating autoantibodies against thyroid-stimulating hormone receptors (TSHRs) localized on thyrocytes' membranes of intact thyroid follicles. The presence of HT after GD or the concomitant combination of these two autoimmune entities ending in HT-depending hypothyroid state is well known. However, occurrence of GD after primary hypothyroidism due to CLT is very rare since thyrocytes with their TSHRs are promptly lost. We report a case in which hyperthyroidism occurred seven months after presentation of primary hypothyroidism and discuss potential mechanisms involved.

Hypothyroidism is associated with changes in bone metabolism. The impact of hypothyroidism and the associated autoimmunity on the mediators of bone turnover in Hashimoto's thyroiditis (HT) is not known. In this study, we assessed the levels of OPG, RANKL, and IL-6 along with markers of bone formation as osteocalcin (OC) and markers of bone resorption as type 1 collagen C telopeptide (CTX) and tartrate-resistant acid phosphatase isoform 5b (TRAcP 5b) in 30 hypothyroid and 30 euthyroid premenopausal HT patients and 20 healthy premenopausal controls. We found that TRAcP 5b (p = 0.006), CTX (p = 0.01), OC (p = 0.017), and IL-6 (p Thyroid autoimmunity might have a unique impact on OPG/RANKL levels apart from the resultant hypothyroidism.

A case of presumed Hashimoto's encephalopathy (HE) is presented. The presentation included memory loss, delusions, functional decline and culminated in a generalized seizure. Anti-thyroid antibodies were detected and symptoms resolved with prednisolone. Patients with HE may present with prominent neuropsychiatric symptoms, attract psychiatric diagnoses and present to psychiatric services. Primarily a diagnosis of exclusion, HE should be considered in cases of encephalopathy in which standard investigations are negative.

Pericardial Effusion as a Presenting Symptom of Hashimoto Thyroiditis: A Case Report

Alberto Leonardi

2017-12-01

Full Text Available Background: Hashimoto thyroiditis (HT is the most frequent cause of acquired hypothyroidism in paediatrics. HT is usually diagnosed in older children and adolescents, mainly in females and is rare in infants and toddlers with cardiac involvement, including pericardial effusion, that can be found in 10% to 30% of adult HT cases. In this paper, a child with HT and pericardial effusion as the most important sign of HT is described. Case presentation: A four-year-old male child suffering for a few months from recurrent abdominal pain sometimes associated with vomiting underwent an abdominal ultrasound scan outside the hospital. This led to the identification of a significant pericardial effusion. At admission, his family history revealed that both his mother and maternal grandmother suffered from HT and that both were treated with l-thyroxine (LT4. The clinical examination did not reveal any pathological signs other than a palpable thyroid. His weight was 21 kg (78th percentile, his height was 101.8 cm (12th percentile and his body max index (BMI was 20.26 (96th percentile. On a chest radiograph, his heart had a globular appearance and the lung fields were normal. An echocardiography confirmed and determined the effusion amount (max, 23 mm; 600 mL with light impairment of the heart kinetics. The ECG showed sinus bradycardia with a normal ST tract. Based on the blood test results, an infectious cause of the pericardial fluid excess was considered unlikely. Thyroid function testing revealed very high thyrotropin (TSH, 487 μIU/mL; normal range, 0.340–5.600 μIU/mL and low serum-free thyroxine (fT4, 0.04 ng/dL; normal range, 0.54–1.24 ng/dL levels. High thyroid peroxidase antibody titres in the blood were evidenced (>1500 UI/L; normal values, 0.0–9.0 UI/L. The thyroid ultrasound was consistent with thyroiditis.

The relationship between thyroid-stimulating immunoglobulins, measured by both radioreceptor assay and adenylate cyclase stimulation, and the HLA alleles was studied in 41 patients with Hashimoto's thyroiditis. TSH binding-inhibiting immunoglobulins (TBII) were detected in 9 (22%) patients, and human thyroid adenylate cyclase-stimulating immunoglobulins (HTACS) were found in 21 (51%) patients. Only 2 patients were positive in both assays, and an inverse relationship was observed between TBII and HTACS. In the 21 HTACS-positive patients, HLA-Dw5 was found in 1 subject, compared to 8 of the 20 HTACS-negative patients (P < 0.01), while 4 of the 9 TBII-positive patients had HLA-Dw5 compared to 5 of the 32 TBII-negative subjects (P = 0.09).No significant relations were observed between the presence of HTACS or TBII and HLA-Dw3 or HLA-B8. It is concluded that TBII and HTACS are produced independently in Hashimoto's thyroiditis, and that the production of these autoantibodies seems to be related to the HLA-D region in this disease.

There is no family history of AA or any autoimmune disorders. The onset of AA, in the both sisters was in early childhood (3 and 7 years of age. The clinical and laboratory examinations showed engagement of the scalp with round or oval large patches of alopecia, without involvement of the body hairs and nails. There were also alterations of thyroid gland function, positive TMA (Thyroid Microsomal Antibodies and Rö-data of Pituitary adenoma as well as episodes of allergic rhinitis (in one of the sisters, and bronchial asthma (in the other. According to Ikeda’s classification, they have an "Atopic type" AA. We suppose that the observed case is not an occasional coincidence of AA and TH. HLA Aw32B18 determination could be support our suggesting about the familial pattern of these autoimmune diseases.

Thyroid inflammation has been commonly seen in recent decades, due to a series of factors and is considered as the most frequent thyroid illness. It is characterized by some distinctive traits, which include morphological and hormonal modifications, often in association with an elevated anti-thyroid autoantibody title. The aim of the therapy is to improve symptoms as fast as possible, treating inflammation and subsequent hypothyroidism, when present. Therefore, we evaluated the efficacy of a Food Supplement (FS) containing enzymes which is commonly used in various inflammatory processes and is able to modulate immune reactions during inflammation in a very rapid and efficacious way. An open, controlled study was then designed and 45 patients with Hashimoto thyroiditis were enrolled and divided into 3 groups (FS alone; thyroid hormones alone; FS plus thyroid hormones). Blood, morphological and subjective parameters were considered. The results obtained indicate that the FS used in our study is efficacious and safe when used alone and/or in combination with thyroid hormones in the treatment of autoimmune thyroiditis, as documented by the improvement of the majority of the parameters considered. The efficacy was considered faster than thyroid hormones alone as far as subjective symptomatology is considered. In conclusion, the use of the food supplement evaluated herein during inflammation may be considered an additional tool in clinicians’ hands, when facing patients with autoimmune thyroiditis, especially in presence of subjective symptomatology, in order to rapidly alleviate it.

Subclinical hypothyroidism, commonly caused by Hashimoto thyroiditis (HT), is a risk factor for cardiovascular diseases. This disorder is defined as merely having elevated serum thyroid stimulating hormone (TSH) levels. However, the upper limit of reference range for TSH is debated recently. This study was to determine the cutoff value for the upper normal limit of TSH in a cohort using the prevalence of Hashimoto thyroiditis as "gold" calibration standard. The research population was medical staff of 2856 individuals who took part in health examination annually. Serum free triiodothyronine (FT3), free thyroxine (FT4), TSH, thyroid peroxidase antibody (TPAb), thyroglobulin antibody (TGAb) and other biochemistry parameters were tested. Meanwhile, thyroid ultrasound examination was performed. The diagnosis of HT was based on presence of thyroid antibodies (TPAb and TGAb) and abnormalities of thyroid ultrasound examination. We used two different methods to estimate the cutoff point of TSH based on the prevalence of HT. Joinpoint regression showed the prevalence of HT increased significantly at the ninth decile of TSH value corresponding to 2.9 mU/L. ROC curve showed a TSH cutoff value of 2.6 mU/L with the maximized sensitivity and specificity in identifying HT. Using the newly defined cutoff value of TSH can detect patients with hyperlipidemia more efficiently, which may indicate our approach to define the upper limit of TSH can make more sense from the clinical point of view. A significant increase in the prevalence of HT occurred among individuals with a TSH of 2.6-2.9 mU/L made it possible to determine the cutoff value of normal upper limit of TSH.

Full Text Available OBJETIVO: Relatar o caso clínico de uma criança portadora de doença celíaca, tireoidite de Hashimoto e síndrome de Noonan. DESCRIÇÃO DE CASO: Menina de dez anos e seis meses, branca, apresentando história de diarreia líquida há cinco meses e "aumento da barriga". Ao exame, mostrava peso de 20.580g (pOBJECTIVE: To describe the clinical case of a child with celiac disease, Hashimoto's thyroiditis and Noonan syndrome. CASE DESCRIPTION: A Caucasian girl aged ten years and six months had liquid diarrhea for five months, and a "distended belly". At the physical exam: weight of 20,580g (p<3, length of 114cm (p<3, hydrated, anemic 2+/4+ and conscious. The patient presented triangular facies, apparent ocular hypertelorism, antimongoloid position of the palpebral fissures, ears with low implantation, micrognathia, short neck and pectus excavatum. The abdomen was globular, flaccid and painless; the liver was 2cm below the right costal margin. Lymphedema in right upper limb and lower limb edema was also noted. Laboratory exams showed microcytic and hypochromic anemia, deficit of total proteins, Hashimoto's thyroiditis and a 5-year delay in bone age. Abdominal ultrasonography showed the bowel slightly dilated. Due to lymphedema and chronic diarrhea, the initial hypothesis was intestinal lymphangiectasis, which was confirmed by a jejunal biopsy, which also showed celiac disease. The genetic evaluation revealed a 46XX karyotype and a clinical diagnosis of Noonan syndrome. COMMENTS: Different autoimmune diseases can be associated. In this case, the celiac disease and the Hashimoto's thyroiditis are possibly related to the presence of HLA system antigens. However, the association of the celiac disease with the Noonan syndrome is very rare, and this is the third report in the literature.

Hashimoto's thyroiditis (HT) is considered to be a risk factor for the formation of papillary carcinoma. The association of IgG4-related sclerosing disease with tumor is reported to be as sporadic cases in many organs. In this study, it was intended to re-classify the HT diagnosed cases on the basis of the existence of IgG4 (+) plasma cells; to investigate the clinicopathologic and histopathologic features of the both groups; and in addition, to evaluate the papillary carcinoma prevalence in IgG4 (+) and IgG4 (-) HT cases as well as the prognostic parameters between these groups. Totally 59 cases between the years 2008-2013, 29 of which contain Hashimoto thyroiditis diagnosis in total thyroidectomy materials, and 30 of which contain the diagnosis of HT+papillary carcinoma, were included in the study. The materials were immunohistochemically applied IgG and IgG4; and the cases were classified in two groups as IgG4-positive HT and IgG4-negative HT containing cases, on the basis of IgG4/IgG rate. All histopathologic and clinicopathologic parameters between these two groups, as well as their association with papillary carcinoma were investigated. Thirty eight (64.4%) of total 59 cases were NonIgG4 thyroiditis, and 21 (35.5%) were IgG4 thyroiditis. Tumors were detected in 14 (36.8%) of the NonIgG4 thyroiditis cases, and in 16 (76.1%) of the IgG4 thyroiditis cases. The association of IgG4 thyroiditis with tumor is statistically significant (p thyroiditis cases. Perithyroidal extension was detected in six of the cases with tumor, and five of the six cases were IgG4 thyroiditis cases. The association of IgG4 (+) HT cases with increased papillary carcinoma prevalence is suggestive of that IgG4 (+) plasma cells can play a role in carcinogenesis in papillary carcinomas developed in HTs, without a chronic sclerosing ground. In addition, although the number of cases is limited, the high-association of IgG4 (+) plasma cells with adverse prognostic parameters such as

Myxedema coma (MC) is a rare, but often fatal endocrine emergency. The majority of cases that occur in elderly women with long-standing primary hypothyroidism are caused by particular triggers. Conversely, MC of central origin is extremely rare. Here, we report a case of MC with both central and primary origins. A 56-year-old woman was transferred to our hospital due to loss of consciousness; a chest x-ray demonstrated severe cardiomegaly. Low body temperature, bradycardia, and pericardial effusion suggested the presence of hypothyroidism. Endocrinological examination revealed undetectable levels of serum free thyroxine (T(4)) and free triiodothyronine (T(3)), whereas serum thyroid-stimulating hormone (TSH) levels were not elevated. The woman's serum anti-thyroid peroxidase antibody and anti-thyroglobulin antibody tests were positive, indicating that she had Hashimoto's thyroiditis. Provocative tests to the anterior pituitary revealed that she had TSH and growth hormone (GH) deficiency; however, GH levels were restored after supplementation with levothyroxine for 5 months. This was not only a rare case of MC with TSH deficiency and Hashimoto's thyroiditis; the patient also developed severe osteoporosis and possessed transient elevated levels of serum carcinoembryonic antigen (CEA). This atypical case may suggest the role of anterior pituitary hormone deficiencies, as well as hypothyroidism, in the regulation of bone metabolism.

Hashimoto thyroiditis (HT) and the fibrosing variant of Hashimoto thyroiditis (FVHT) are immune-mediated tumefactive lesions of the thyroid. Immunoglobulin G4-related disease (IgG4-RD) is now a widely recognised multi-organ system disease characterised by elevated serum and tissue concentrations of IgG4. In this study, the authors address several unresolved questions pertaining to the relationship between HT and FVHT, and the association of each of these diseases with IgG4-RD. The authors evaluated 28 consecutive cases of HT and nine cases of FVHT. The clinical, demographic and serological data were recorded. The slides were stained immunohistochemically using antibodies to IgG4 and IgG and the quantitative analysis was recorded. Data on thyroid function tests were available on seven cases of FVHT and 14 cases of HT. Based on the availability of data, hypothyroidism was noted in 62% (9/14) of HT and 86% of FVHT (6/7). FVHT demonstrated an exaggerated lobular pattern with lobules separated by cellular storiform-type fibrosis, resembling fibrosis seen in other forms of IgG-RD. The median IgG4 counts per high power field (×40) in HT and FVHT were 2.3 and 22, respectively. The median IgG4:IgG ratios in HT and FVHT were 0.11 and 0.58, respectively. The authors propose that FVHT belongs to the spectrum of IgG4-RD. Although a proportion of cases of HT show elevated numbers of IgG4 positive plasma cells, these cases lack the histological features typically associated with IgG4-RD, and thus the relationship between HT and IgG4-RD remains unproven.

Hashimoto's thyroiditis (HT) seems to have favourable prognostic impact on papillary thyroid cancer (PTC), but data were obtained analysing all disease stages. Given that HT-related microenvironment involves solely the thyroid, we aimed to assess the relationship between HT, as detected through pathological assessment, and outcome in intrathyroidal PTC. This was a multicentre, retrospective, observational study including 301 PTC with no evidence of extrathyroidal disease. Primary study endpoint was the rate of clinical remission. Auxiliary endpoint was recurrence-free survival (RFS). HT was detected in 42.5% of the cohort and was associated to female gender, smaller tumour size, lower rate of aggressive PTC variants and less frequent post-surgery radio-iodine administration. HT showed relationship with significantly higher rate of clinical remission ( P  < 0.001, OR 4, 95% CI 1.78-8.94). PTCs with concomitant HT had significantly longer RFS, as compared with non-HT tumours ( P  = 0.004). After adjustment for other parameters affecting disease outcome at univariate analysis (age at diagnosis, histology, tumour size and multifocality), prognostic effect of HT remained significant ( P  = 0.006, OR 3.28, 95% CI 1.39-7.72). To verify whether HT could optimise the identification of PTCs with unfavourable outcome, we assessed the accuracy of 'non-HT status' as negative prognostic marker, demonstrating poor capability of identifying patients not maintaining clinical remission until final follow-up (probability of no clinical remission in PTCs without HT: 21.05%, 95% CI 15.20-27.93). In conclusion, our data show that HT represents an independent prognostic parameter in intrathyroidal PTC, but cannot improve prognostic specificity. © 2017 Society for Endocrinology.

We aimed to evaluate the prevalence of lactose intolerance (LI) in patients with Hashimoto's thyroiditis(HT) and the effects of lactose restriction on thyroid function in these patients. Eighty-three HT patients taking L-thyroxine (LT4) were enrolled, and lactose tolerance tests were performed on all patients. Lactose intolerance was diagnosed in 75.9 % of the patients with HT. Thirty-eight patients with LI were started on a lactose-restricted diet for 8 weeks. Thirty-eight patients with LI (30 euthyroid and 8 with subclinical hypothyroidism), and 12 patients without LI were included in the final analysis. The level of TSH significantly decreased in the euthyroid and subclinical hypothyroid patients with LI [from 2.06 ± 1.02 to 1.51 ±1.1 IU/mL and from 5.45 ± 0.74 to 2.25 ± 1.88 IU/mL,respectively (both P0.05). Lactose intolerance occurs at a high frequency in HT patients. Lactose restriction leads to decreased levels of TSH, and LI should be considered in hypothyroid patients who require increasing LT4 doses,have irregular TSH levels and are resistant to LT4 treatment.

Recent studies have identified common genetic variants associated with TSH, free T4 and thyroid peroxidase antibodies, but it is unclear whether these differ between patients with Hashimoto's disease and Graves' disease. To examine whether 11 common genetic variants differ between Graves' disease and Hashimoto's disease. We genotyped 11 common variants in a discovery cohort of 203 Australian patients with autoimmune thyroid disease (AITD). Two variants with significant or suggestive associations were analysed in a replication cohort of 384 Danish patients. For rs753760 (PDE10A), the minor allele frequency in Graves' disease and Hashimoto's disease was 0·38 vs. 0·23, respectively, (P = 6·42 × 10 -4 ) in the discovery cohort, 0·29 vs. 0·24 (P = 0·147) in the replication cohort and 0·32 vs. 0·24 in combined analysis (P = 0·0021; all analyses adjusted for sex). In healthy controls from Busselton, the frequency was 0·29, significantly different from Hashimoto's disease but not Graves' disease. For rs4889009 (MAF gene region), the frequency of the minor G-allele in Graves' disease and Hashimoto's disease was 0·48 vs. 0·36 (P = 0·0156) in the discovery cohort, 0·48 vs. 0·34 (P = 1·83 × 10 -4 ) in the replication cohort and 0·48 vs. 0·35 in the combined analysis (P = 7·53 × 10 -6 ); in controls, the frequency was 0·38, significantly different from Graves' disease but not Hashimoto's disease. After further adjustment for smoking, associations with rs4889009 remained significant, whereas those with rs753760 were not. Common variants in PDE10A and MAF gene regions may influence whether patients with AITD develop Graves' disease or Hashimoto's disease. © 2015 John Wiley & Sons Ltd.

Highlights: • Virtual Touch Tissue Quantification could provide quantitative measurements to estimate tissue stiffness noninvasively. • Severity of Hashimoto's thyroiditis could affect stiffness of extra-nodular thyroid tissue significantly. • Shear wave velocity of malignant nodules significantly higher than that of benign nodules. • Acoustic Radiation Force Impulse imaging is useful in differential diagnosis between malignant/benign thyroid nodules with HT. - Abstract: Objectives: This study aimed at detecting whether Virtual Touch Tissue Quantification (VTQ) could be applied to differentiate between benign and malignant thyroid nodules with chronic autoimmune Hashimoto's thyroiditis (HT). Methods: Convenient ultrasound and Virtual Touch Tissue Quantification were performed in 118 patients with 140 thyroid nodules with histology results. The HT group consisted of 46 patients with 58 nodules. The non-HT group consisted of 72 patients with 82 nodules. Results: The stiffness of extra-nodular thyroid tissue could be significantly affected by the severity of chronic autoimmune thyroiditis. The shear wave velocity of thyroid benign nodules and malignant nodules did not significantly differ in the HT group as compared with the non-HT group (benign nodules: 2.13 ± 0.32 m/s vs 1.98 ± 0.48 m/s, P = 0.122; malignant nodules: 3.32 ± 0.77 m/s vs 3.30 ± 0.74 m/s, P = 0.894). In two groups, the shear wave velocity of malignant nodules is significantly higher than that of benign nodules (HT group: 3.32 ± 0.77 m/s vs 2.13 ± 0.32 m/s; non-HT group: 3.30 ± 0.74 m/s vs 1.98 ± 0.48 m/s, P < 0.001). The best cutoff point for shear wave velocity between malignant and benign thyroid nodules was 2.75 m/s. Conclusions: Virtual Touch Tissue Quantification technology could be performed in the differential diagnosis between malignant thyroid nodules and benign thyroid nodules independently from the coexistence of chronic autoimmune thyroiditis

To elucidate alteration of peripheral T cell subsets in thyroid tumors, the author enumerated T cell subsets in peripheral blood by indirect immunofluorescent method, using monoclonal antibodies (CD3, CD4 and CD8) in 17 cases of thyroid cancer, 12 cases of thyroid adenoma, and 16 cases of adult healthy subjects as controls. Diagnoses were confirmed histopathologically in thyroid cancer and adenoma, and were established on the basis of commonly accepted clinical and biochemical criteria in Hashimoto's thyroiditis. The blood was drawn from veins of (he patients and control subjects in Pusan National University Hospital during the period of January to October 1990. The results obtained were summarized as follow: 1) The percentage of CD3+ cells was significantly decreased in thyroid cancer as compared with healthy subjects. 2) The percentage of CD4+ cells was not different among thyroid cancer, thyroid adenoma, hashimoto's thyroiditis and control subjects each other. 3) The percentage of CD8+ cells was significantly decreased in thyroid cancer as compared with adult healthy subjects, and tended to be decreased as compared with thyroid adenoma and Hashimoto's thyroiditis. 4) The CD/CDH ratio was significantly increased in thyroid cancer as compared with control subjects, and tended to be increased as compared with thyroid adenoma and Hashimoto's thyroiditis. On the basis of (the results, it can be suggested that the immunodysfunction may be due to decreased suppressor/cytotoxic T cells in thyroid cancer.

An association between Helicobacter pylori (H pylori) infection as environmental risk factors for Hashimoto thyroiditis (HT) has been reported. We investigated this hypothesis in women in which HT is more common. Serum immunoglobulin G antibodies against H pylori (enzyme-linked immunosorbent assay), CagA protein (Western blot assay), circulating antibodies to thyroid antigens, mainly thyroperoxidase (TPOAbs) and thyroglobulin (TgAbs), were tested in 101 females with HT and 111 non-HT control women without a history of autoimmune disease. Thyroid function, socioeconomic status at childhood, and family history of thyroid malfunction were also studied. Forty-seven HT women (46.5%) tested seropositive for H pylori versus 48 controls (43.2%; P = 0.63). The prevalence of anti-CagA antibodies was 21.3% in HT-infected patients and 31.2% in infected controls (P = 0.352). Women with HT were older than the controls at a significance level of 0.03, and higher prevalence of hypothyroidism (69% vs 13.5%, respectively) and family history of thyroid malfunction (59% vs 34%, respectively) (P thyroid malfunction was independently associated with an increased risk of HT (odds ratio 3.39, 95% confidence interval 1.86-6.18, P thyroid malfunction is a risk factor for HT.

In the context of a study on the tolerance of rapeseed meal in B.U.T. 6 turkeys, thyroid glands were histologically and immunohistochemically examined because of potential thyreostatic effects. In all groups including the controls with no rapeseed meal in their food, there was a high incidence of lymphocytic infiltration and thyroiditis (14% of thyroids with moderate to severe lymphocytic thyroiditis). Thirty per cent of mononuclear inflammatory cells were immunohistochemically identified as T cells. There were occasional accumulations of PAX-5 labelled cells, indicating germinal centre development. These lesions resemble Hashimoto's disease in humans. The effect on thyroid function is unknown. Mild hypothyreosis might enhance productivity but also explain dispositions towards diseases seen in context with thyroid dysfunction such as skin diseases (foot pad disease?) and cardiovascular problems. Further studies on thyroid function in these turkeys are needed. Journal of Animal Physiology and Animal Nutrition © 2013 Blackwell Verlag GmbH.

Myxedema psychosis is uncommon in patients with primary hypothyroidism. Most often, this disease state can be found in patients with Hashimoto thyroiditis or after total thyroidectomy. Chronic hypothyroidism can lead to an insidious onset of psychiatric symptoms in patients, such as dementia, delirium, psychosis, hallucinations, and coma. A 31-year-old man with an unremarkable medical history was brought to the psychiatric emergency department for new-onset aggression, paranoid behavior, and hallucinations for 4 days. Initial test results showed a thyroid-stimulating hormone level of 306.0 mIU/L and a free thyroxin level of 0.24 ng/dL. No other clinical or laboratory abnormalities were found. A diagnosis of myxedema psychosis was established, and the patient was treated with tapering doses of intravenous hydrocortisone and 0.1 mg of intravenous levothyroxine daily. On hospital day 3, his mental status began to improve, and he was discharged on day 4. Myxedema psychosis is rarely the initial presenting symptom of hypothyroidism, especially in the absence of other abnormal clinical or laboratory findings.

Background: Besides genetic factors, it is known that some trace elements, as Selenium, Copper, and Zinc are essential for thyroid gland fuction and thyroid hormone metabolism. Moreover, there were some metals effect that suggested patterns associated with overt thyroid disease. Aim of study: Hashimoto thyroiditis (HT), chronic autoimune inflamation of thyroid gland with cosequtive hipothyroidism, is common disease in Serbia, and we thought it is worthwile to explore potential effects of essential and toxic metals and metalloides on thyroid function and ability to restore euthyroid status of them. Results: This cross-sectional, case-control, study investigated the status of essential elements (Selenium,Copper,and Zinc) and toxic metals and metalloides (Al, Cr, Mn, Co, As, Cd, Sb, Ba, Be, Pb and Ni) from the blood of 22 female, patients with Hashimoto thyroiditis and overt hypothyroidism, and compared it with those of 55 female healthy persons. We tried to establish the presence of any correlation between previous mentioned elements and thyroid function in hypothyroid patients and healthy participants. Conclusions: The results of our study suggested that the blood concentration of essential trace elements, especially the ratio of Copper, and Selenium may influence directly thyroid function in patients with HT and overt hypothyroidism.Thus, our findings may have implication to life-long substitution therapy in terms of l-thyroxine dose reduction. Furthermore, for the first time, our study shown potential toxic effect of Cadmium on thyroid function in HT patients, which may implicate the dose of l-thyroxine substitution. © Georg Thieme Verlag KG Stuttgart · New York.

We aimed to investigate the effects of oxidative stress in the pathogenesis and progression of Hashimoto's thyroiditis (HT). Forty euthyroid and 40 subclinical hypothyroid patients older than 18 years and not yet had received treatment were enrolled in the study. In the 9 months follow-up, 14 of the HT patients developed overt hypothyroidism. The mean total oxidant status (TOS) and oxidative stress index (OSI) were higher in patients who developed overt hypothyroidism than those who did not (p  .05). Multivariable Cox regression model showed thyroid stimulating hormone level (HR = 1.348, p OSI ratio (HR = 2.349, p OSI level, being over 2.96 with 92.9% sensitivity and 62.5% specificity, predicts the risk of hypothyroidism. Oxidative stress may be an effective risk factor in the development of overt hypothyroidism in HT.

This study aimed to evaluate the ultrasonographic pattern of cervical lymph nodes (CLNs) and whether levothyroxine with prednisone therapy is effective for lymphadenopathy in patients with Hashimoto thyroiditis (HT). This retrospective study was looking at patients with confirmed diagnosis of HT who underwent comprehensive neck ultrasound examination. We reviewed sonographic findings in 127 patients with HT, 234 euthyroid patients with goiter, and 122 healthy subjects. In addition, 30 untreated HT patients with cervical lymphadenopathy were recruited for the levothyroxine with prednisone therapy. We rescanned the patients 9 months after treatment with levothyroxine and prednisone. Patients with HT had a higher rate of CLN detection on ultrasound than euthyroid patients with goiter and healthy subjects at cervical levels III, IV, and VI (P thyroid volume, thyroid nodule volume, CLN volume, symptom score, and cosmetic grade of 30 HT patients were remarkably decreased (P Hashimoto thyroiditis seems to be associated with an increased rate of detection of CLNs with abnormal sonographic features, particularly at cervical levels III, IV, and VI. Therapy with levothyroxine with prednisone is effective for cervical lymphadenopathy in patients with HT.

Fetal/neonatal thyrotoxicosis is a rare but potentially life-threatening condition. It is most commonly observed in poorly controlled Graves disease during pregnancy. Here we describe a fetus/newborn patient with thyrotoxicosis who was born of a woman with Hashimoto thyroiditis and levothyroxine-treated hypothyroidism. Transplacental passage of stimulating thyrotropin (TSH) receptor antibodies, which were measured by a cell-based bioassay, was the underlying mechanism of fetal/neonatal thyrotoxicosis, although the mother had no history of hyperthyroidism. Diagnosis and management of fetal hyperthyroidism can be challenging. TSH receptor antibody testing should be considered in pregnant women with any history of autoimmune thyroid disease and symptoms of fetal hyperthyroidism. Copyright © 2017 by the Endocrine Society

Hashimoto thyroiditis (HT) is the most frequent thyroid autoimmune disease, while papillary thyroid cancer (PTC) is one of the most common endocrine malignancies. A few patients with HT also develop PTC. The aim of this study was to analyze cytokine profiles in patients with PTC accompanied with autoimmune HT in comparison with those in patients with PTC alone or HT alone and healthy subjects. Cytokine levels were determined in supernatants obtained from phytohemagglutinin (PHA)-stimulated whole blood cultures in vitro. The concentrations of selected cytokines: Th1-interferon gamma (IFN-γ); Th2-interleukin 4 (IL-4), interleukin 5 (IL-5), interleukin 6 (IL-6), interleukin 10 (IL-10) and interleukin 13 (IL-13); Th9-interleukin 9 (IL-9); and Th17-interleukin 17 (IL-17A) were measured using multiplex cytokine detection systems for human Th1/Th2/Th9/Th17/Th22. We found that PTC patients with HT produced significantly higher concentrations of IL-4, IL-6, IL-9, IL-13 and IFN-γ than PTC patients without HT. In conclusion, autoimmune HT affects the cytokine profile of patients with PTC by stimulating secretion of Th1/Th2/Th9 types of cytokines. Th1/Th2 cytokine ratios in PTC patients with associated autoimmune HT indicate a marked shift toward Th2 immunity.

Riedel's thyroiditis, known as invasive fibrous thyroiditis, is a very rare form of chronic thyroiditis. It is hard to make the diagnosis without surgical biopsy. We present a case of Riedel's thyroiditis in a 52-year-old female with past history of Hashimoto's thyroiditis. She suffered from bilateral neck pain, which radiated to both lower jaws. The erythrocyte sedimentation rate was 125 mm/hour. Subacute thyroiditis superimposed on Hashimoto's thyroiditis was diagnosed and treated with steroid. However the response was poor and she had a history of severe peptic ulcer. To avoid inducing the peptic ulcer by steroid, she received bilateral subtotal thyroidectomy. During surgery, the thyroid had severe adhesion to surrounding soft tissue and the pathology showed Riedel's thyroiditis. The neck pain improved after thyroidectomy. Tamoxifen has been given for 8 months and the size of remnant thyroid decreased to 8 mm. We concluded that combined thyroidectomy and tamoxifen successfully cured a patient with Riedel's thyroiditis.

The authors investigated the incidence of antithyroglobulin antibodies and antibodies and antimicrosomal antibodies measured by tanned red cell hemagglutination method in subjects suffering from various thyroid disorders. 1) In 15 normal patients, neither suffering from any thyroid diseases nor from any other autoimmune disorders, the antithyroglobulin antibodies were all negative, but the antimicrosomal antibody was positive only in one patient (6.7%). 2) The antithyroglobulin antibodies were positive in 31.5% (34 patients) of 108 patients with various thyroid diseases, and the antimicrosomal antibodies were positive in 37.0% (40 patients). 3) of the 25 patients with Graves' diseases, 7 patients (28.0%) showed positive for the antithyroglobulin antibodies, and 9 (36.0%) for the antimicrosomal antibodies. There was no definite differences in clinical and thyroid functions between the groups with positive and negative results. 4) Both antibodies were positive in 16 (88.9%) and 17 (94.4%) patients respectively among 18 patients with Hashimoto's thyroiditis, all of them were diagnosed histologically. 5) Three out of 33 patients with thyroid adenoma showed positive antibodies, and 3 of 16 patients with thyroid carcinoma revealed positive antibodies. 6) TRCH antibodies demonstrated negative results in 2 patients with subacute thyroiditis, but positive in one patient with idiopathic primary myxedema. 7) The number of patients with high titers(>l:802) was 16 for antithyroglobulin antibody, and 62.5% (10 patients) of which was Hashimoto's thyroiditis. Thirteen (65.0) of 20 patients with high titers (>l:802) for antimicrosomal antibody was Hashimoto's thyroiditis. TRCH test is a simple, sensitive method, and has high reliability and reproducibility. The incidences and titers of antithyroglobulin antibody and antimicrosomal antibody are especially high in Hashimoto's thyroiditis.

To prospectively investigate, during a 5-year follow-up, whether the prognosis of thyroid function with Hashimoto thyroiditis (HT) is different in euthyroid girls with Turner syndrome (TS) than in euthyroid girls without TS. In 66 TS girls and 132 non-TS girls with euthyroid HT and similar thyroid functional test results at HT diagnosis, we followed up the evolution of thyroid status over time. At the end of follow-up, the TS girls exhibited higher TSH levels, lower fT4 levels, and lower prevalence rates of both euthyroidism and subclinical hypothyroidism, but higher prevalence rates of both overt hypothyroidism and hyperthyroidism, irrespective of the karyotype. An association with TS is able to impair the long-term prognosis of thyroid function in girls with HT. Such an effect occurs irrespective of thyroid functional test results at HT diagnosis and is not necessarily linked with a specific karyotype. © 2016 S. Karger AG, Basel.

Full Text Available INTRODUCTION Hashimoto's thyroiditis (HT is a common cause of goitre and hypothyroidism in children and adolescents. Spontaneous remission may occur in up to 50% patients, but the development of hypothyroidism is possible. OBJECTIVE We investigated the clinical manifestations, course and long-term outcome of HT. METHOD We reviewed charts of 43 children (36 females with HT, mean age at presentation 12.3 years, and mean follow-up duration 4.6 years. RESULTS HT is five times more common in females. The common complaints leading to referral were goitre in 19 children (44.3%, diffuse in 17 children (89.5%. As to the prevalence of goitre, it accounted for significantly more referrals in females (14 girls, and 5 boys; 73.7% vs 26.3%, t-test; p<0.005. Goitre was either isolated in 15 (34.4% or associated with other complaints in 4 children: anemia in 7 (16.2%, fatigue in 5 (11.8%, increased appetite in 4 (9.7%, weight gain in 3 (7.0%, growth retardation in 2 children (4.7%, at irregular menses in 3 pubertal girls. Hypothyroidism was present in 18 patients (41.1%, 7 (38.8% on initial admission, and 11 (61.8% had the mean follow-up duration of 4.6 years. There were 25 euthyroid HT patients (59.9%. The family history of the thyroid disease was positive in 16 children (37.1% and 12 of them (71.4% had hypothyroidism. There were 6 patients (13.9% in whom the disease was associated with some other autoimmune disease. CONCLUSION HT is five times more common in females. The usual complaints leading to referral were diffuse goitre, which accounted for significantly more referrals in females. A positive family history of autoimmune thyroid disease is associated with a higher risk of hypothyroidism in children with HT. Hypothyroid patients may appear in higher percentage of children and adolescents than previously reported.

Although IgG4-related disease is characterized by extensive infiltration of IgG4-positive plasma cells and lymphocytes of various organs, the details of this systemic disease are still unclear. We screened serum total IgG levels in the patients with Hashimoto thyroiditis (HT) to illustrate the prevalence of IgG4-related thyroiditis in HT. Twenty-four of 94 patients with HT (25.5%) had elevated serum IgG levels and their serum IgG4 was measured. Five of the 24 cases had more than 135 mg/dL of IgG4, which is the serum criterion of IgG4-related disease. One was a female patient who was initially treated as Graves' disease and rapidly developed a firm goiter and hypothyroidism. The biopsy of her thyroid gland revealed that follicular cells were atrophic with squamous metaplasia, replaced with fibrosis, which was compatible with the fibrous variant of HT. Immunohistochemical examination revealed diffuse infiltration of IgG4-positive plasma cells, and the serum IgG4 level was 179 mg/dL. The levels of IgG and IgG4 were positively correlated with the titers of anti-thyroglobulin antibody or anti-thyroid peroxidase antibody. In conclusion, at least a small portion of patients with HT with high titers of anti-thyroid antibodies may overlap the IgG4-related thyroiditis.

Full Text Available Abstract Introduction This paper concerns the analysis of the features obtained from thyroid ultrasound images in left and right transverse and longitudinal sections. In the image analysis, the thyroid lobe is treated as a texture for healthy subjects and patients with Hashimoto’s disease. The applied methods of analysis and image processing were profiled to obtain 10 features of the image. Then, their significance in the classification was shown. Material In this study, the examined group consisted of 29 healthy subjects aged 18 to 60 and 65 patients with Hashimoto's disease. For each subject, four ultrasound images were taken. They were all in transverse and longitudinal sections of the right and left lobe of the thyroid, which gave 376 images in total. Method 10 different features obtained from each ultrasound image were suggested. The analyzed thyroid lobe was marked automatically or manually with a rectangular element. Results The analysis of 10 features and the creation for each one of them their own decision tree configuration resulted in distinguishing 3 most significant features. The results of the quality of classification show accuracy above 94% for a non-trimmed decision tree.

Steroid-Responsive Epilepsia Partialis Continua with Anti-Thyroid Antibodies: A Spectrum of Hashimoto's Encephalopathy

Full Text Available Background: When a neuropsychiatric symptom due to encephalopathy develops in a patient with anti-thyroid antibodies, especially when the symptom is steroid-responsive, Hashimoto's encephalopathy (HE needs to be included in the differential diagnosis of the patient. Although HE is an elusive disease, it is thought to cause various clinical presentations including seizures, myoclonus, and epilepsia partialis continua (EPC. Case Report: We present the case of a 33-year-old Japanese woman who acutely developed EPC in the right hand as an isolated manifestation. A thyroid ultrasound showed an enlarged hypoechogenic gland, and a thyroid status assessment showed euthyroid with high titers of thyroid antibodies. A brain MRI revealed a nodular lesion in the left precentral gyrus. Corticosteroid treatment resulted in a cessation of the symptom. Conclusions: A precentral nodular lesion can be responsible for steroid-responsive EPC in a patient with anti-thyroid antibodies and may be caused by HE. The serial MRI findings of our case suggest the presence of primary demyelination, with ischemia possibly due to vasculitis around the demyelinating lesion.

It has been reported that the BRAF (V600E) mutation is related to a low frequency of background Hashimoto thyroiditis (HT); however, there are not many factors known to be related to the development of HT. The aim of this study was to determine whether patients with both papillary thyroid carcinoma (PTC) and HT show aggressive features, by investigating the clinicopathological features of HT in patients with PTC. A database of patients with PTC who underwent thyroidectomy between October 2008 and August 2012 was collected and reviewed. All 2464 patients were offered a thyroidectomy, and DNA was extracted from the atypical cells in the surgical specimens for detection of the BRAF (V600E) mutation. Clinical and pathological characteristics were also investigated. Four hundred and fifty-two of 1945 (23.2%) patients were diagnosed with HT, and of these, 119 (72.1%) had a BRAF (V600E) mutation. HT was not significantly associated with the BRAF (V600E) mutation (P < 0.001) and extrathyroidal extensions (P = 0.005) but was associated with a low stage (P = 0.011) and female predominance (P < 0.001). In a subgroup analysis for gender, HT was associated with a low probability of BRAF (V600E) mutations in both genders (P < 0.001 for both females and males). Also, recurrence was significantly associated with HT (OR 0.297, CI 0.099-0.890, P = 0.030), lymph node ratio (OR 2.545, CI 1.092-5.931, P = 0.030), and BRAF (V600E) mutation (OR 2.075, CI 1.021-4.217, P = 0.044). However, there was no relationship with clinicopathological factors or with death. Our results show that HT in patients with PTC is associated with a low probability of BRAF (V600E) mutations. Moreover, HT was correlated with some factors that were associated with less aggressive clinical features and inversely related to recurrence. Therefore, these results may be useful to predict whether PTC concurrent with HT exhibits a better prognosis than PTC alone.

To clarify a relationship between A-bomb exposure and Hashimoto's disease and that between Hashimoto's disease and carcinoma of the thyroid gland, autopsy cases of Hashimoto's disease (112 cases in Hiroshima and 43 cases in Nagasaki) were examined. Incidence of Hashimoto's disease was not related to exposure doses and ages at the time of exposure. Incidence of carcinoma of the thyroid gland from Hashimoto's disease was 1.3% (2 cases), and there was no relationship between them. Incidence of ovarian cancer as cancer accompanied with Hashimoto's disease was significantly high, but that of stomach cancer was significantly low. Incidence of total cancer from Hashimoto's disease was also significantly low. Incidences of rheumatic fever and rheumatoid arthritis which were collagen diseases and diseases similar to them complicated by Hashimoto's disease was significantly high. (Tsunoda, M.)

2012-04-01

Full Text Available Background: Both hypothyroidism and Hashimoto's thyroiditis (HT can rarely be associated with cerebellar ataxia. Severe essential tremor (ET as well as bilateral thalamic deep brain stimulation (DBS may lead to subtle cerebellar signs. Case Report: We report a 74-year-old male with hypothyroidism and a 20-year history of ET who developed cerebellar ataxia after bilateral thalamic DBS. Extensive workup revealed elevated thyroid stimulating hormone and thyroperoxidase antibody titers confirming the diagnosis of HT. Discussion: Our case demonstrates multiple possible causes of cerebellar ataxia in a patient, including hypothyroidism, HT, chronic ET, and bilateral thalamic DBS. Counseling of patients may be appropriate when multiple risk factors for cerebellar ataxia coexist in one individual.

A hallmark of regulatory B cells is IL-10 production, hence their designation as IL-10+ B cells. Little is known about the ability of self-antigens to induce IL-10+ B cells in Graves' disease (GD), Hashimoto's thyroiditis (HT), or other autoimmune disease. Here we pulsed purified B cells from 12 HT...... patients, 12 GD patients, and 12 healthy donors with the thyroid self-antigen, thyroglobulin (TG) and added the B cells back to the remaining peripheral blood mononuclear cells (PBMCs). This procedure induced IL-10+ B-cell differentiation in GD. A similar tendency was observed in healthy donors...... and correlated with free T3 levels in GD patients. IL-10+ B cells from both patient groups displayed CD25 or TIM-1 more frequently than did those from healthy donors. B-cell expression of two surface marker combinations previously associated with regulatory B-cell functions, CD24hiCD38hi and CD27+CD43+, did...

Monozygotic twin pairs discordant for Hashimoto's thyroiditis share a high proportion of thyroid peroxidase autoantibodies to the immunodominant region A. Further evidence for genetic transmission of epitopic "fingerprints"

To examine this......, we compared the distribution of TPOAb epitopic fingerprints between healthy monozygotic (MZ) co-twins and siblings to patients with clinically overt HT with a control group of euthyroid subjects, matched for sex and age, but without autoimmune thyroid disease (AITD) among their first-degree relatives...

Branchial cleft-like cysts in Hashimoto's thyroiditis: A case report and literature review.

Miyazaki, Masaya; Kiuchi, Shizuka; Fujioka, Yasunori

2016-05-01

We report an extremely rare case of branchial cleft-like cysts in Hashimoto's thyroiditis. The patient was a 77-year-old man with a growing mass in the anterior neck. Ultrasonography and computed tomography revealed a cystic lesion with septum in the left thyroid and multiple small cystic lesions in the right thyroid. Lymph node swelling of the cervical region, supraclavicular fossa and submandibular region was also observed. Left thyroidectomy and lymph node dissection were performed. Histologically, cysts were lined by stratified squamous epithelium and dense lymphoid tissue having conspicuous follicle formation surrounded the epithelial lining. Solid cell nest (SCN)-like aggregations were seen in the thyroid parenchyma adjacent to the cyst walls and a small number of thyroid follicles were observed in the fibrous wall. Immunohistochemically, it is suggested that both the cyst lining and SCN-like aggregations are originally from thyroid follicles. Although, the exact histogenesis of branchial cleft-like cysts remains unclear, there are probably two different processes for its development, one is of branchial cleft origin and the other is mere squamous metaplasia, while in our case the latter is suggested. Herein, we report our new case and update information about branchial cleft-like cysts that appears in the literature. © 2016 Japanese Society of Pathology and John Wiley & Sons Australia, Ltd.

The purpose of the study was to explore the diagnostic performance of acoustic radiation force impulse (ARFI) elastography in differential diagnosis between benign and malignant thyroid nodules in patients with coexistent Hashimoto's thyroiditis (HT). A total of 141 pathological proven nodules in 141 HT patients (7 males and 134 females, mean age 50.1 years, range 23-75 years) received conventional ultrasound (US), elasticity imaging (EI) and ARFI elastography, including virtual touch tissue imaging (VTI) and virtual touch tissue quantification (VTQ), before surgery. Shear wave velocity (SWV) and SWV ratio were measured for each nodule on VTQ. The US, EI and ARFI elastography features were compared between benign and malignant nodules in HT patients. Receiver operating characteristic curve (ROC) analyses and area under curve (AUC) were performed to assess the diagnostic performance. Pathologically, 70 nodules were benign and 71 nodules were malignant. Significant differences were found between benign and malignant nodules in HT patients for EI (EI score) and ARFI (VTI grade and SWV) (all P value benign and malignant thyroid nodules in HT patients. The diagnostic performance of ARFI elastography is better than EI.

The incidence of the autoimmune thyroid disease Hashimoto thyroiditis (HT) has increased in recent years, and increasing evidence supports the contribution of excess iodine intake to thyroid disease. In this study, we examined the status of autophagy and apoptosis in thyroid tissues obtained from patients with HT, and we determined the effects of excessive iodine on the autophagy and apoptosis of thyroid follicular cells (TFCs) in an attempt to elucidate the effects of excess iodine on HT development. Our results showed decreases in the autophagy-related protein LC3B-II, and increases in caspase-3 were observed in thyroid tissues from HT patients. Interestingly, the suppression of autophagy activity in TFCs was induced by excess iodine in vitro, and this process is mediated through transforming growth factor-β1 downregulation and activation of the Akt/mTOR signaling pathway. In addition, excess iodine induced autophagy suppression and enhanced reactive oxygen species (ROS) production and apoptosis of TFCs, which could be rescued by the activation of autophagy. Taken together, our results demonstrated that excess iodine contributed to autophagy suppression and apoptosis of TFCs, which could be important factors predisposing to increased risk of HT development.

The patients with Hashimoto thyroiditis must be investigated mainly for secondary hyperparathyroidism due to vitamin D deficiency/insufficiency. Parathyroid scintigraphy has no place in the diagnosis of primary, secondary or tertiary hyperparathyroidism or in the decision for surgical treatment. Parathyroid scintigraphy is a useful preoperative technique for the localization of the pathological parathyroid glands.

Full Text Available Biogenic amines are integral part of nearly every cell. In present study, we used method of acidic extraction of histamine (His, of polyamines putrescine (Put, spermidine (Spd and catecholamines epinephrine (Epi and norepinephrine (NE from human serum; precolumn derivatization with dansyl chloride, and LC/DAD analysis of the biogenic amines, in aim to monitor differences of their levels in patients with diabetes mellitus, chronic urticaria, and Hashimoto's thyroiditis, compared to healthy subjects, and to observe them as possible markers for immune mediated diseases. Method of retention times was used for determination of serum biogenic amines. We found statistically significant differences in putrescine and histamine levels in diabetes mellitus patients; putrescine, histamine, spermidine and epinephrine levels in chronic urticaria patients compared to healthy controls, and putrescine and spermidine levels in Hashimoto's thyroiditis patients, compared to controls. Norepinephrine was found only in serum of patients with chronic urticaria. The values of recovery, evaluated in controls, varied between 85.7% and 106.7%. The statistically significant changes in putrescine, histamine, spermidine and epinephrine levels in patients compared to healthy people reflects the existence of biochemical disturbances in mentioned immune-mediated diseases.

To explore the relationship between IL-1β expression and two common autoimmune thyroid diseases: Hashimoto thyroiditis (HT) and Graves' disease (GD). qRT-PCR, Quantiglo ELISA, and flow cytometry were used to evaluate the expression levels of IL-1β in serum, peripheral blood mononuclear cells (PBMCs), and thyroid tissue samples from patients with HT or GD. Local infiltration of monocytes was assessed by immunohistochemical study of patients' thyroid tissue samples. Although no significant differences in IL-1β levels were found between samples of serum from patients with HT or GD and normal controls, we found that IL-1β mRNA and protein levels in PBMCs of HT patients were significantly higher than those of patients with GD, which were in turn higher than the level in normal controls. In addition, IL-1β mRNA was also increased in thyroid gland tissue from patients with HT compared to those with GD, and this was accompanied by increased local infiltration of monocytes into thyroid tissues. Correlation analysis of the clinical samples validated the association of high IL-1β levels with the pathogenesis of HT. Our study suggests that IL-1β may be an active etiologic factor in the pathogenesis of HT and thus present a new target for novel diagnostics and treatment.

Elevated levels of reactive oxygen species (ROS) have been proposed as a risk factor for the development of papillary thyroid carcinoma (PTC) in patients with Hashimoto thyroiditis (HT). However, it has yet to be proven that the total levels of ROS are sufficiently increased to contribute to carcinogenesis. We hypothesized that if the ROS levels were increased in HT, ROS-related genes would also be differently expressed in PTC with HT. To find differentially expressed genes (DEGs) we analyzed data from the Cancer Genomic Atlas, gene expression data from RNA sequencing: 33 from normal thyroid tissue, 232 from PTC without HT, and 60 from PTC with HT. We prepared 402 ROS-related genes from three gene sets by genomic database searching. We also analyzed a public microarray data to validate our results. Thirty-three ROS related genes were up-regulated in PTC with HT, whereas there were only nine genes in PTC without HT (Chi-square p-value < 0.001). Mean log2 fold changes of up-regulated genes was 0.562 in HT group and 0.252 in PTC without HT group (t-test p-value = 0.001). In microarray data analysis, 12 of 32 ROS-related genes showed the same differential expression pattern with statistical significance. In gene ontology analysis, up-regulated ROS-related genes were related with ROS metabolism and apoptosis. Immune function-related and carcinogenesis-related gene sets were enriched only in HT group in Gene Set Enrichment Analysis. Our results suggested that ROS levels may be increased in PTC with HT. Increased levels of ROS may contribute to PTC development in patients with HT.

Autoimmune thyroid diseases (AITDs) are often accompanied by vitiligo, and the sera of patients with vitiligo often demonstrate increased frequencies of thyroid autoantibodies. In this study, we investigated the expression of melanocyte-associated antigens in tissues from patients with Hashimoto's thyroiditis (HT) without vitiligo using immunohistochemistry. Tissues of HT without vitiligo, as well as normal thyroid tissues, were both negative for the expression of NKI/beteb, gp100, tyrosinase-related protein 1 (TRP1), HMB-45 and S100, whereas they were positive for the expression of tyrosinase-related protein 2 (TRP2), lysosome-associated membrane protein 1 (LAMP1) and CD69. Tyrosinase (TYR) was only detected in tissues of HT, and levels of LAMP1 and CD69 were higher in tissues of HT than in normal thyroid tissues (p vitiligo and HT that might represent an immunological basis for secondary HT associated with vitiligo.

Warthin-Finkeldey type giant cells were first described in autopsies performed on young children who died during the highly lethal measles epidemic in Palermo during the winter of 1908. The cells had 8-15 nuclei without identifiable cytoplasm within the germinal centers of lymphoid organs resembling megakaryocytes. We describe a case of Hashimoto thyroiditis with an enlarging substernal throid mass. The resection specimen contained many Warthin-Finkeldey-Like Cells (WFLC) in an extranodal marginal zone lymphoma (MALT type) with focal transformation to diffuse large B-cell lymphoma. The WFLC showed nuclear features similar to those of neighboring follicular dendritic cells (FDCs), favoring the hypothesis that these cells might be the product of fusion of FDCs. This is supported by immunostaining results and the occurrence of similar cells in follicular dendritic cell sarcomas and in "dysplastic" FDCs in hyaline vascular type Castleman disease, a possible precursor of follicular dendritic cell tumors.

Full Text Available Hashitoxicosis is an initial, transient, hyperthyroid phase that rarely affects patients with Hashimoto thyroiditis. We present here an unusual case of a child with Hashimoto thyroiditis and recurrent hyperthyroidism. A 4 yr 6/12 old male was diagnosed by us with autoimmune subclinical hypothyroidism (normal free T4, slightly elevated TSH, and elevated TG antibody titer. Two years and 6/12 later he experienced increased appetite and poor weight gain; a laboratory evaluation revealed suppressed TSH, elevated free T4, and normal TSI titer. In addition, an I123 thyroid uptake was borderline-low. A month later, the free T4 had normalized. After remaining asymptomatic for 3 years, the patient presented again with increased appetite, and he was found with low TSH and high free T4. Within the following 3 months, his free T4 and TSH normalized. At his most recent evaluation, his TSH was normal and the free T4 was borderline-high; the TG antibody titer was still elevated and the TSI titer was negative. To our knowledge, this is the first patient reported with Hashimoto thyroiditis and recurrent hyperthyroidism. This case exemplifies the variability of the manifestations and natural history of Hashimoto thyroiditis and supports the need for a long-term evaluation of patients with autoimmune thyroid disease.

He was, however, found to have TSH = 18.6 MIU/ml, T3reverse = 0.44nmol/L, T4 = 0.8ng/dl and Anti-Thyroid-Peroxidase AB titer >1000 IU/ml. Based on the above findings the patient was diagnosed with Hashimoto's encephalopathy and his mental status showed dramatic improvement (MMS 30/30 with high dose prednisone. Hashimoto's encephalopathy is rare disorder of presumed autoimmune origin characterized by cognitive decline, seizures, neuro-psychiatric symptoms, high titers of Anti-Thyroid-Peroxidase AB, and a positive response to steroids.

The relation between thyroid neoplasms and chronic lymphocytic thyroiditis (CLT) is controversial. While it is accepted that focal lymphocytic thyroiditis develops secondarily to malignancy, it is not clear whether diffuse lymphocytic thyroiditis has a tendency to develop into thyroid cancer. The aim of this study was to investigate the relation between CLT and malignant tumours of the thyroid and evaluate the surgical approach to CLT cases. In this study, 917 patients operated on for thyroid diseases were investigated retrospectively. Seventy-seven (8.4%) patients histopathologically diagnosed as having CLT (either non-specific or Hashimoto's thyroiditis) were investigated for any concurrent malignant neoplasm. Fifteen patients in whom CLT and thyroid malignancy were coexisting were included in the study. In the pathological evaluation of 917 cases, malignancy in the thyroid was found in 97 (10.6%) cases. Seventy-seven cases were categorised as CLT. Of these 77, 16 (20.8%) were Hashimoto's thyroiditis (specific CLT) and the other 61 (79.2%) were non-specific CLT. In 15 cases, thyroid malignancy was found to be concurrent with CLT. Of the malignities, nine (60%) were papillary carcinoma, three (20%) medullar carcinoma, one (6.6%) follicular carcinoma, one (6.6%) Hurthle cell carcinoma, and one (6.6%) lymphoma. In our series, the rate of the development of malignancy against the background of CLT was 19.48%, while the rate in the groups without CLT was 9.76%, with a statistically significant difference between the groups (p = 0.008). CLT cases should be evaluated more carefully in terms of malignancy. If a nodule is detected on thyroiditis, the minimal surgical intervention should be lobectomy. Total thyroidectomy should be considered as preferable to subtotal thyroidectomy because of its many advantages such as controlling thyroiditis, removing the probability of reoperation, and hormonal stability.

Full Text Available Primary thyroid lymphoma is a rare malignancy, representing 2-8% of all thyroid malignancies and 1-2% of all extranodal lymphomas. The majority of cases concern non-Hodgkin`s lymphoma of B cell origin, following by Hodgkin’s disease, T cell lymphomas and rarely marginal zone B-cell mucosa-associated lymphoid tissue (MALT lymphomas. MALT lymphomas have been associated with long-standing autoimmune Hashimoto`s thyroiditis. We present the case of a 44-years-old woman with thyroid MALT lymphoma in the background of multinodular goiter of autoimmune origin.

MIR141 expression differentiates Hashimoto Thyroiditis from PTC and benign thyrocytes in Irish archival thyroid tissues

Full Text Available MicroRNAs (miRNAs are small non-coding RNAs approximately 22 nucleotides in length that function as regulators of gene expression. Dysregulation of miRNAs has been associated with initiation and progression of oncogenesis in humans. Our group has previously described a unique miRNA expression signature, including the MIR200 family member MIR141, which can differentiate papillary thyroid cancer (PTC cell lines from a control thyroid cell line. An investigation into the expression of MIR141 in a series of archival thyroid malignancies (n=140; classic PTC, follicular variant PTC, follicular thyroid carcinoma (FTC, Hashimoto thyroiditis (HT, or control thyrocytes was performed. Each cohort had a minimum of 20 validated samples surgically excised within the period 1980 - 2009. A subset of the HT and cPTC cohorts (n=3 were also analysed for expression of TGFβR1, a key member of the TGFβ pathway and known target of MIR141. Laser capture microdissection was used to specifically dissect target cells from formalin-fixed paraffin-embedded archival tissue. Thyrocyte- and lymphocyte-specific markers (TSHR and LSP1 respectively confirmed the integrity of cell populations in the HT cohort. RNA was extracted and quantitative RT-PCR was performed using comparative CT (ΔΔCT analysis. Statistically significant (p<0.05 differential expression profiles of MIR141 were found between tissue types. HT samples displayed significant downregulation of MIR141 compared to both classic PTC and control thyrocytes. Furthermore, TGFβR1 expression was detected in cPTC samples but not in HT thyrocytes. It is postulated that the down-regulation of this miRNA is due, at least in part, to its involvement in regulating the TGFβ pathway. This pathway is exquisitely involved in T-cell autoimmunity and has previously been linked with HT. In conclusion, HT epithelium can be distinguished from cPTC epithelium and control epithelium based on the relative expression of MIR141.

Full Text Available CONTEXT: Medical centers worldwide report an increased frequency of Hashimoto's thyroiditis (HT and thyroid cancer (TC, two environmentally influenced diseases. In Sicily, data on HT are available for the province of Messina (1975-2005; data on TC are available for the whole island (2002-2004, with the volcanic province of Catania having the highest incidence. OBJECTIVE: To replicate in Catania, on comparable years, the HT data of Messina. DESIGN METHODS SETTING: Review of the clinical records of patients in years 1995-2005 to compare presentation and yearly changes of HT. During 1995-2005, records were computer stored in the Endocrine Divisions of the University Hospitals of Catania and Messina, two tertiary referral centers. RESULTS: Catania is outnumbered by Messina (742 vs. 3,409 HT patients. Similar were the linear increase in the yearly number of HT patients, rates of thyroid dysfunctions though with different proportions of subclinical and overt hypothyroidism, and rates of positiveness for TgAb or TPOAb. Different were age and its yearly trend; gender distribution and rates of the sonography variants, though yearly trends were similar. CONCLUSION: The HT epidemics is smaller in Catania, with changes in presentation overlapping partially those in Messina. Whatever environmental factors might be involved, they (and/or their intensity were not necessarily the same in these provinces. Intriguingly, the expected number of TC in HT patients with thyroid nodules in Catania is congruent with that of the general population of this province, but it is far less than in the Messina province. Thus, TC and HT incidences could be influenced by distinct environmental factors.

Levothyroxine (L-T4) treatment of euthyroid children with Hashimoto thyroiditis (HT) is a controversial issue. We conducted a prospective, randomized, controlled clinical trial. Out of 79 identified euthyroid patients, 59 started the study; 25 patients (21 female, 4 male; age: 11.8 ± 2.3 years) received L-T4 at a mean dose of 1.6 µg/kg (SD, 0.8) daily, and 34 (27 female, 7 male; age: 12.6 ± 1.2 years) were not treated. Patients developing subclinical hypothyroidism during follow-up (n = 13) were treated with L-T4 and removed from the observation group. As the main outcome measures, thyroid gland volume (determined by ultrasound) as well as serum levels of TSH, free T4, and antibodies against thyroid peroxidase and thyroglobulin were assessed every 6 months for 36 months. At the start, the mean thyroid volume (standard deviation score, SDS) was 2.5 in the treatment group and 1.6 in the observation group. There was a constant decline in mean thyroid volume (SDS) from 2.13 (month 12) to 1.12 (month 30) in the treated group, with a delta thyroid volume of -1.01 SDS. In the observation group, the mean delta thyroid volume increased to +0.27 SDS. The change of the delta thyroid volume was statistically significantly different between both groups during the 12- and 30-month time points (p thyroid function and serum thyroid antibodies. L-T4 treatment can decrease the thyroid volume in euthyroid children with HT, but the effect is limited to a definite time period. © 2015 S. Karger AG, Basel.

The most common reason of acquired hypothyroidism is autoimmune (Hashimoto) thyroiditis. Autoimmune thyroiditis can be atrophic or goitrogenic. Atrophic autoimmune thyroiditis (ATT) related acquired hypothyroidism causes interruption of growth, obesity, and bone age retardation in early ages while goitrogenic thyroiditis has a higher incidence rate and mostly presents with diffuse goiter. We discuss the effects of hypothyroidism on various systems through a case found to have pericardial effusion during the echocardiography performed after cardiac murmur was detected and later diagnosed with ATT related hypothyroidism.

The purpose of the study - to determine the feature of the vascular endothelial growth factor (VEGF) and thyroid-stimulating hormone (TSH) expression in the thyroid gland (TG) in various thyroid diseases. Material - thyroid tissue (operative material) with histologically confirmed diagnosis: 10 - follicular adenoma, 17 - multinodular goiter, 8 - thyroiditis Hashimoto, 8 - papillary carcinoma, 10 - intact (normal) thyroid samples (forensic autopsy). The immunohistochemical study of the material showed the following results: the increase of the Hürtle cells population 40 % or more indicates a hyperthyroidism tendency despite TSH+ receptor status. Under the thyroid pathology TSH and VEGF expression appears in thyrocytes and also in microvascular endothelial cells. VEGF expression is below the norm in the Hashimoto thyroiditis. VEGF is involved not only in angiogenesis, but in pathophysiological shifts in thyroid tissue. Microvessel density (MVD) and TSH positive receptor status under the thyroid pathology testify the absence of the endothelial cells transformation, however, this index can not serve as a biopothential prognostic marker of thyroid disease.

Encephalopathy occasionally occurs in association with thyroid disorders, but most of these are treatable. These encephalopathies include a neuropsychiatric disorder associated with hypothyroidism, called myxedema encephalopathy. Moreover, Hashimoto's encephalopathy (HE) has been recognized as a new clinical disease based on an autoimmune mechanism associated with Hashimoto's thyroiditis. Steroid treatment was successfully administered to these patients. Recently, we discovered that the serum autoantibodies against the NH2-terminal of α-enolase (NAE) are highly specific diagnostic biomarkers for HE. Further, we analyzed serum anti-NAE autoantibodies and the clinical features in many cases of HE from institutions throughout Japan and other countries. Approximately half of assessed HE patients carry anti-NAE antibodies. The age was widely distributed with 2 peaks (20-30 years and 50-70 years). Most HE patients were in euthyroid states, and all patients had anti-thyroid (TG) antibodies and anti-thyroid peroxidase (TPO) antibodies. Anti-TSH receptor (TSH-R) antibodies were observed in some cases. The common neuropsychiatry features are consciousness disturbance and psychosis, followed by cognitive dysfunction, involuntary movements, seizures, and ataxia. Abnormalities on electroencephalography (EEG) and decreased cerebral blood flow on brain SPECT were common findings, whereas abnormal findings on brain magnetic resonance imaging (MRI) were rare. HE patients have various clinical phenotypes such as the acute encephalopathy form, the chronic psychiatric form, and other particular clinical forms, including limbic encephalitis, progressive cerebellar ataxia, and Creutzfeldt-Jakob disease (CJD)-like form. The cerebellar ataxic form of HE clinically mimics spinocerebellar degeneration (SCD) and is characterized by the absence of nystagmus, absent or mild cerebellar atrophy, and lazy background activities on EEG. Taken together, these data suggest that the possibility of

Although thyroidal uptake of gallium-67 has been described in several thyroid disorders, gallium-67 scanning is not commonly used in the evaluation of thyroid disease. Thyroidal gallium-67 uptake has been reported to occur frequently with subacute thyroiditis, anaplastic thyroid carcinoma, and thyroid lymphoma, and occasionally with Hashimoto's thyroiditis and follicular thyroid carcinoma. A patient is described with progressive systemic sclerosis who, while being scanned for possible active pulmonary involvement, was found incidentally to have abnormal gallium-67 uptake only in the thyroid gland. Fine needle aspiration cytology of the thyroid revealed Hashimoto's thyroiditis. Although Hashimoto's thyroiditis occurs with increased frequency in patients with progressive systemic sclerosis, thyroidal uptake of gallium-67 associated with progressive systemic sclerosis has not, to our knowledge, been previously described. Since aggressive thyroid malignancies frequently are imaged by gallium-67 scintigraphy, fine needle aspiration cytology of the thyroid often is essential in the evaluation of thyroidal gallium-67 uptake

Recent studies show an association between autoimmune thyroiditis and systemic sclerosis (SSc) and suggest that this condition may interfere with the ES phenotype. However these studies evaluate the autoimmune thyroiditis as a whole and none of them specifically addresses Hashimoto's thyroiditis (HT) in SSc. To investigate the presence of HT in SSc patients and its possible association with disease manifestations. Clinical manifestations of hypothyroidism, TSH and anti-thyroid auto antibodies (anti-TPO. anti TBG and TRAb) were studied in 56 patients with SSc. SSc patients with HT were compared with SSc patients without thyroiditis. HT was observed in 19.64% of patients with SSc. No association was observed between HT and the different forms of disease or profile of autoantibodies. Likewise, there was no difference between the mean modified Rodnan score and presence of Raynaud's phenomenon, scars, digital necrosis, myositis, arthritis, sicca symptoms, esophageal dysmotility and scleroderma renal crisis when the groups were compared. On the other hand, patients with HT had higher frequency of pulmonary hypertension in relation to patients without HT (66.6% vs 22.5%, p=0.016). In the studied sample patients with ES and HT had higher prevalence of pulmonary hypertension. Long-term follow-up studies with a larger number of TH and SSc patients are needed to confirm these data. Copyright © 2014 Elsevier Editora Ltda. All rights reserved.

Evaluation of diffuse thyroid diseases by computed tomography and 123I thyroidal uptake

Understanding the iodine kinetics in the thyroid is useful for the diagnosis of a patient with diffuse thyroid disease. In this study, 9 controls and 50 patients with diffuse thyroid diseases, we evaluated diffuse thyroid diseases with 123 I thyroidal uptake and volume, iodine concentration, and net iodine content measured by computed tomography. There was no significant correlation between volume, iodine concentration, and net iodine content of the thyroid and 123 I thyroidal uptake. The thyroid volume in Graves' and Hashimoto's diseases was significantly larger than that in the control group. The thyroid iodine concentration in Graves' and Hashimoto's diseases was significantly smaller than that in the control group. The thyroid net iodine content in Hashimoto's disease was significantly smaller than that in the control group. Although most of the patients with Graves' disease had more increased radioiodine thyroidal uptake than the control group, there was no significant difference between them in the mean of the thyroid net iodine content. But the variance of net iodine contents in the former was significantly larger than that in the latter. The thyroid net iodine content was very low in all patients with very high thyroglobulin hemaggrugated antibody (TGHA) value although it was nearly normal in some patients with normal TGHA value. It was suggested that iodine concentration and net iodine content might be determined not only by iodine uptake but also by release and/or leakage of iodine compounds from the thyroid, which might depend on some antithyroid antibodies.

Myxedema Coma due to Hashimoto Thyroiditis: A Rare but Real Presentation of Failure to Thrive in Infancy.

Heksch, Ryan A; Henry, Rohan K

2018-05-04

Hashimoto thyroiditis (HT) is uncommon in infancy, and myxedema coma (MC) is even less common. While prior reports have documented these entities separately, to our knowledge, MC in combination with HT has not been reported before in this age group. A 10-month-old female presented with ptosis, lethargy, dysphagia, and failure to thrive (FTT). She developed hypotension, bradycardia, hypothermia, and apnea requiring intubation. Initial thyroid-stimulating hormone was 422 μIU/mL, and free thyroxine was < 0.5 ng/dL, despite the presence of a normal thyroid newborn screen (NBS). Of note, sepsis workup was unremarkable. With the diagnosis of MC, treatment with intravenous levothyroxine was initiated, although after hydrocortisone administration to avert the possibility of an adrenal crisis, despite a random cortisol of 16.4 μg/dL. Based on positive thyroid antibodies suggesting HT, autoimmune workup later revealed positive acetylcholinesterase antibodies consistent with a diagnosis of ocular myasthenia gravis. MC may be a cause of altered mental status in infancy and may simultaneously be associated with FTT on presentation. With the presence of a normal thyroid NBS, autoimmunity should be entertained as the etiology of profound hypothyroidism, as positive thyroid antibodies may prompt an exploration for coexisting diseases which may explain other presenting features. © 2018 S.

One hundred and forty one patients with diffuse goiter were studied In order to evaluate four of Fisher's criteria for the diagnosis of Hashimoto's thyroiditis and to compare them with the result of thyroid aspiration biopsy. The following criteria were Included in the analysis: a physical characteristics of the gland; b appearance of the radioisotope scan; c plasma TSH concentration; d serum tilters of antithyroid antibodies. It was found that neither criteria was satisfactory in terms of sensitivity or specificity when compared with the result of the aspiration cytology. Ac. cordingly, we favor the use of the latter provided that adequate material is obtained and that an expert reading is performed.

Inflammatory processes of the thyroid represents a main proportion of the gland's pathology but the majority of them are treated by medical methods, surgery being indicated. In 14 cases (3%) from 464 operations for different thyroid conditions we have encountered authentic inflammatory lesions in 9 cases of Hashimoto's thyroiditis (two associated with papillary thyroid carcinoma and one with malignant lymphoma), two cases of Riedel's thyroiditis and respectively de Quervain thyoiditis, tuberculous thyroiditis and actynomicosis one case each. The common lymphoplasmacytic infiltration in Basedow's disease was not considered likewise as the inflammatory nespecific lesions encountered in benign and malignant pathology of the gland. The clinical and imagistic data, biological evaluation and titer of anticorps but particularly the paraffine examination together with intraoperative estimations are decisive for the diagnosis. Firm diagnosis of thyroiditis was rarely affirmed before operation, surgical indication being formulated on clinical criterions dominated by cancer suspicion. Among these are diffuse or (multi)nodular thyromegaly with a dominant nodule with recent appearance and rapid growing in temporal and geographic proximity of Chemobyl disaster, with hard consistence, celsian or compressive features and adenopathy. More added the imagistic signs but especially suspect aspects of the FNAB (follicular or with Hürthle cells smears) and also of the frozen sections. Certainty diagnosis was established by paraffine examination not always without hesitations or reexamination (Hashimoto's thyroiditis diagnosed in one case was finally a malignant lymphoma). Large removal decided after intraoperative findings induced for the most of patients a definitive hypothyroidism. All the diagnosis resources must be exhausted for the diagnosis of the inflammatory lesions of the thyroid to avoid unnecessary surgery. On the other side the chronic overstimulation by the TSH of the

Bei 50 % dieser Hashimoto-Patientinnen war bereits im Vorfeld eine Hypothyreose bekannt, bei den restlichen 25 Patientinnen handelte es sich allerdings um eine Erstdiagnose im Rahmen des Screenings für LS. Aufgrund der hohen Prävalenz von Hashimoto-Thyreoiditis in LS-Patientinnen empfehlen wir bei allen Frauen mit LS ein Screening auf TPO- und TG-Antikörper. Bei erhöhten Titern sollte eine Abklärung mittels Schilddrüsensonogramm sowie eine Bestimmung von basalem "thyroid-stimulating hormone" (TSH, freiem T3 und freiem T4 erfolgen. In der Schilddrüsensprechstunde sollten Frauen mit Hashimoto-Thyreoiditis gezielt nach chronischen bzw. rezidivierenden anogenitalen Beschwerden, insbesondere Pruritus, Brennen oder Dyspareunie befragt werden. Bei positiver Anamnese ist eine Zuweisung an einen auf Vulvaerkrankungen spezialisierten Facharzt für Gynäkologie sinnvoll.

Understanding the iodine kinetics in the thyroid is useful for the diagnosis of a patient with diffuse thyroid disease. In this study, 9 controls and 50 patients with diffuse thyroid diseases, we evaluated diffuse thyroid diseases with {sup 123}I thyroidal uptake and volume, iodine concentration, and net iodine content measured by computed tomography. There was no significant correlation between volume, iodine concentration, and net iodine content of the thyroid and {sup 123}I thyroidal uptake. The thyroid volume in Graves' and Hashimoto's diseases was significantly larger than that in the control group. The thyroid iodine concentration in Graves' and Hashimoto's diseases was significantly smaller than that in the control group. The thyroid net iodine content in Hashimoto's disease was significantly smaller than that in the control group. Although most of the patients with Graves' disease had more increased radioiodine thyroidal uptake than the control group, there was no significant difference between them in the mean of the thyroid net iodine content. But the variance of net iodine contents in the former was significantly larger than that in the latter. The thyroid net iodine content was very low in all patients with very high thyroglobulin hemaggrugated antibody (TGHA) value although it was nearly normal in some patients with normal TGHA value. It was suggested that iodine concentration and net iodine content might be determined not only by iodine uptake but also by release and/or leakage of iodine compounds from the thyroid, which might depend on some antithyroid antibodies.

The aim of this study was to evaluate proteins oxidation in plasmas of two autoimmune thyroid diseases (AITD): Graves' disease (GD) and Hashimoto Thyroiditis (HT), and to determine whether oxidative modification of thyroid antigens (T.Ag) enhanced the reactivity of autoantibodies in plasmas of AITD patients compared with the reactivity towards native T.Ag. Carbonyl and thiol groups and MDA-protein adducts were assessed spectrophotometric methods in plasmas of 74 AITD patients and 65 healthy controls. The reactivities immunoglobulin (Ig)G autoantibodies towards malondialdéhyde (MDA)-modified T.Ag, hydrogen peroxide (H 2 O 2 )-modified T.Ag, native T.Ag and native derm were checked by enzyme-linked immunosorbent assay (ELISA). Evaluation of oxidized proteins exhibited high levels of MDA bound to proteins and carbonyl groups, as well as reduced thiol level in plasmas of AITD patients by comparison to healthy controls (p thyroid stimulating hormone level in HT patients in the other (r = 0.65, p < 0.001). The data suggest that high production of H 2 O 2 probably occurred during hormone synthesis could contribute to protein oxidation in AITD and to create neoepitopes responsible for autoantibody reactivity's to H 2 O 2 -oxidized T.Ag enhancement. These results provide support to the involvement of oxidative stress in AITD development and/or exacerbation. Copyright © 2017 Elsevier B.V. All rights reserved.

m6o-color immunophenotyping of lymphocyte subsets using a lysed whole blood method was performed in 46 children and adolescents with Hashimoto`s thyroiditis (HT) from contaminated areas and in 18 children with HT from `pure` areas of Belarus. 46 healthy children of matched age and sex distribution were used as control group. Analysis of lymphocyte subsets in children with HT living in contaminated areas showed a considerable decrease in the levels of total lymphocytes, CD8+T cells (T-suppressors), total B cells, and CD5+B cells together with an activation of NK and CD56+, CD8+CD57+T cells (T-killers not restricted by HLA antigens). The study of cellular immunity in children with different doses of incorporated radionuclids revealed that prolonged influence of very small doses of ionizing radiation resulted in significant changes in lymphocyte subsets; interestingly, B cell subsets were the most sensitive to such influence while radiosensitivity of T-killers and NK was the lowest. These changes were the greatest in children with HT with the highest dose of incorporated radionuclides. Significant correlation between the levels of main lymphocyte subsets and the doses of accumulated radionuclids observed in this study also indicated that their relation was dose-dependent.(orig.)

Th primary thyroid lymphoma is a rare neoplasm, above all in children. We present a case of a child with Burkitt's thyroid lymphoma as the only manifestation of this disease, associated to lymphocytic thyroiditis. Clinically, it initiated as a rapidly growing goiter with compressive symptomatology. The X-ray findings are described: hypoechoic and hypodense multiple nodes that affect the right thyroid lobe and isthmus, with extraglandular extension to the vascular space and to the mediastinum. The differential diagnosis is considered with other more frequent thyroid pathologies in this age group. (Author) 14 refs

As a new antibody concept, natural bispecific antibodies (nBsAbs) have been detected in long-term passive immunization and some diseases, but their potential immunomodulatory role remains unclear. Hashimoto thyroiditis (HT) appears to fulfill the condition for nBsAb production but has not yet been characterized. The objective of the study was to identify a new nBsAb against thyroid peroxidase (TPO) and thyroglobulin (Tg) in HT patients and to preliminarily explore its immunomodulatory role. Serum samples were obtained from 136 HT patients, 92 diseased controls, and 99 healthy controls for anti-TPO/Tg nBsAb detection. The relationship between anti-TPO/Tg nBsAb and other clinical parameters was also analyzed. The anti-TPO/Tg nBsAb was detected using a double-antigen sandwich ELISA. Higher nBsAb levels were found to be associated with decreased inflammation in HT patients. The prevalence of anti-TPO/Tg nBsAb in HT was 44.9% (61 of 136), significantly higher than that of diseased controls (2.2%, 2 of 92) (P thyroiditis patients. A new type of nBsAb against TPO and Tg in HT patients is identified. Our data also indicate a protective effect of anti-TPO/Tg nBsAb in the pathogenesis of HT and extend prior knowledge about nBsAb in diseases.

A 33 year old female was admitted to the hospital to study aedema and bocio, A nephrotic syndrome was diagnosed and the renal biopsy demonstrated membranous glomerulonephritis, stage II. She was also diagnosed of Hashimoto's autoinmmune thyroiditis: TSH (41.5 uUl/ml), T4 (0.07 ng/dl), antithyroglobuline (1/2560) and antimicrosome (1/6400). Four year latter she was diagnosed of autoinmmune pancreatitis, without evidence of diabetes mellitus or exocrine pancreatic insufficiency. Eight years latter she was diagnosed of primary autoimmune suprarrenal insufficiency: basal cortisol: 2.7 mcg/dl, post ACTH estimulated cortisol: 5.6 mcg/dl, antinuclear antibody (1/160) and antiparietal (1/320). We present a pluriglandular autoimmune syndrome with membranous glomerulonephritis, thyroiditis, pancreatitis and suprarrenal insufficiency. To the best of our knowledge this complex syndrome has not been previously described.

Struma ovarii is an uncommon type of ovarian tumor derived by germinal cells, characterized by the predominance of thyroid tissue (> 50%); 90-95% of these formations are benign and mainly affect the left ovary, while in 6% of the cases struma ovarii is bilateral. The malignant transformation is a rare condition that often occurs after 50 years. In most instances, diagnosis of malignant struma ovarii is made postoperatively during histological analysis. This tumor appears to derive by one germinal cell through loss of heterozygosity of the androgen receptor gene and of the X chromosome. Clinical symptoms comprise abdominopelvic mass, lower abdominal pain, abnormal vaginal bleeding, and ascites (the occurrence of this condition has been observed in one-third of the cases). The patients with struma ovarii generally do not manifest symptoms related to thyroid hyperfunction, reported only in 8% of the cases, and due to hyperstimulation of the thyroid by auto-antibodies. Thyroid tissue of the struma ovarii, often embedded in a teratoma, may be papillary, follicular or with mixed pattern and it can include elements of mucinous cystoadenomas, Brenner's tumor or carcinoid or melanomas cells. Here the authors report their experience with an unusual case of Hashimoto thyroiditis onset after laparoscopic removal of struma ovarii.

Immune Disorders in Hashimoto’s Thyroiditis: What Do We Know So Far?

Full Text Available This review of literature attempts to identify the factors that are involved in the pathogenesis of Hashimoto thyroiditis, an immune defect in an individual with genetic susceptibility accompanied with environmental factors. The frequency of Hashimoto’s disease is a growing trend and among Caucasians it is estimated at approximately 5%. The dysfunction of the gland may be clinically evident (0.1–2% of the population or subclinical (10–15%. The pathology is diagnosed five to ten times more often in women than men and its incidence increases with the age (the peak of the number of cases is between 45 and 65; however, it can also be diagnosed in children. The pathogenesis of Hashimoto’s thyroiditis is still not fully comprehended. In the etiology of Hashimoto thyroiditis excessively stimulated T CD4+ cells are known to play the most important role. Recent research has demonstrated an increasing role of newly discovered cells such as Th17 (CD4+IL-17+ or T regulatory cells (CD4+CD25+highFoxP3+ in the induction of autoimmune disorders. The process of programmed cell death also plays an equally important role in the pathogenesis and the development of hypothyroidism.

A strong association between malignant lymphoma and Hashimoto's thyroiditis has frequently been reported. However, it is difficult to detect the lymphomatous transformation of Hashimoto's thyroiditis in the early stage. The purpose of the present study was to examine the usefulness of 67 Ga scintigraphy in the diagnosis and evaluation of the therapeutic effects during follow-up, in patients with a suspected diagnosis of primary thyroid lymphoma. Twenty-five patients who were suspected of having primary thyroid lymphoma and had undergone 67 Ga scintigraphy were studied. 67 Ga planar scintigraphy was performed 72 hours after injection of 67 Ga-citrate. The degree and pattern of 67 Ga accumulation were graded visually. Histopathology on biopsy examination revealed thyroid lymphoma in 17 and Hashimoto's thyroiditis in 8 patients. Abnormal accumulation of 67 Ga in the thyroid was seen in all of the 17 thyroid lymphoma cases with additional mediastinal and abdominal involvement in one. Fifteen of 17 thyroid lymphoma patients also underwent 67 Ga scintigraphy 2-4 weeks after chemotherapy and/or radiotherapy. All 15 patients showed diminishing 67 Ga accumulation and a good clinical course. In one patient with local recurrence, abnormal accumulation could be depicted by follow-up scintigraphy. However, diffuse or enlarged accumulation in the thyroid was seen in all of the 8 Hashimoto's thyroiditis cases. The degree of abnormal accumulation in the thyroid in clinically active phase thyroiditis was more intense than that in the chronic phase thyroiditis. 67 Ga scintigraphy was helpful to confirm the diagnosis of thyroid lymphoma and to evaluate the therapeutic effects during follow-up. However, 67 Ga scintigraphy may not always distinguish thyroid lymphoma from Hashimoto's thyroiditis, especially the active phase of the disease. (author)

Objective: To study the influence of 131 I therapy on the autoimmune status in patients with hyperthyroidism from Graves' disease or Hashimoto thyroiditis. Methods: Thyroid-related hormones and antibodies levels were measured with RIA and IL -2, IL-18 levels were measured with ELISA in 48 hyperthyroid patients (including 41 Graves' disease and 7 Hashimoto thyroiditis) both before and 3-6 months after 131 I treatment as well as in 35 controls. Results: After 131 I therapy, at 3-6 months, 16 of the 48 patients were cured, 17 of the 48 were partially relieved and 15 were rendered hypothyroid. Changes of serum IL-12 and IL-18 were as the follows: (1) Before treatment the serum IL-12 and IL-18 levels were significantly higher in the patients than those in controls (P 0.05). (3) Serum IL-18 levels in all patients after treatment were not significantly different (including those cured, partially relieved or rendered hypothyroid, P>0.05). (4) TGA, TMA percentages in all the patients at anytime were significantly higher than those in controls, but there were no significantly differences among the levels in all the patients. (5) Ser- um IL-12 levels were significantly positively correlated with those of IL-18 and TGA, TMA percentages. Conclusion: 131 I therapy is an effective and safe method to control the hyperthyroid symptoms and it carl also ameliorate the immunological derangement. (authors)

Clinical measurement of thyroid autoantibodies in sera of some thyroid disorders have been widely applied since about twenty years ago. We investigated the incidence and titers of both antimicrosomal and antithyroglobulin antibodies in forty eight cases with controls and one hundred and thirty three patients with some form of thyroid disorders. The results were as follows; 1) In controls, antimicrosomal antibodies were positive in 2% but antithyroglobulin antibodies were all negative. 2) In a series of one hundred and thirty three patients with thyroid disease, antimicrosomal antibodies were positive in 44% but antithyroglobulin antibodies were positive in only 15%. 3) The rate disclosing the positive results of antimicrosomal antibodies were 71% in Hashimoto disease, 60% in Graves' disease, and 38% in primary hypothyroidism, respectively. On the other hand, the positive results of antithyroglobulin antibodies showed 21% in Graves' disease, 19% in primary hypothyroidism, and 18% in Hashimoto, disease, respectively. Though there were relatively high rate of both antimicrosomal and antithyroglobulin antibodies in patients with nodular goiter, they were only seven cases in our series. 4) The rate with the extremely high titers of antimicrosomal and antithyroglobulin antibodies (>1 : 160 2 ) was 83% and 67% in Hashimoto's disease, 50% and 67% in primary hypothyroidism, and 41% and 18% in Graves' disease. Accordingly, the thyroid autoantibodies, were commonly found higher positive rate in patients with Hashimoto disease, primary hypothyroidism, and Graves' disease. Among these disorders, the extremely high positive rate of the thyroid autoantibodies was found in patients with Hashimoto's disease.

Ectopic lymphoid follicle infiltration is a key event in Hashimoto thyroiditis (HT). Positive regulatory domain zinc finger protein 1 (PRDM1), which is induced by antigen stimulation, can regulate all lymphocyte lineages. Several groups independently demonstrated that human parvovirus B19 (PVB19) is closely associated with HT. Hence, we determined whether PRDM1 is expressed in HT thyroid tissue and whether there is any correlation between PRDM1 expression and PVB19 in the pathogenesis of HT. We detected PRDM1 expression in HT (n = 86), normal thyroid tissue (n = 30), and nontoxic nodular goiter (n = 20) samples using immunohistochemistry. We also detected PVB19 protein in HT samples in a double-blind manner and analyzed the correlation between the 2 proteins using immunofluorescence confocal detection and coimmunoprecipitation. Furthermore, we detected changes of the expression levels of PRDM1 and PVB19 in transfected primary thyroid follicular epithelial cells using real-time quantitative polymerase chain reaction. We found that PRDM1 protein is significantly highly expressed in the injured follicular epithelial cells in HT (83/86 cases) than in normal thyroid cells (0/30 cases) or in nontoxic nodular goiter cells (0/20 cases) (P thyroid epithelial cells also showed PRDM1 up-regulation after PVB19 NS1 transfection. Our findings suggest a previously unrecognized role of PRDM1 and PVB19 in the pathogenesis of HT. Copyright © 2015 Elsevier Inc. All rights reserved.

Riedel thyroiditis is a benign disease, which is often self-limited. Examinations, such as CT and histologic diagnosis can distinguish it from malignant neoplasms and hashimoto's thyroiditis. Riedel thyroiditis is an uncommon form of chronic thyroiditis in which the thyroid gland is replaced by fibrous tissue. It can be cured by surgery and medicine.

Autoimmune thyroid diseases, including Graves' and Hashimoto's thyroiditis, are the most frequent autoimmune disorders. Viral infection, including Epstein-Barr virus (EBV), is one of the most frequently considered environmental factors involved in autoimmunity. Its role in the development of AITD has not been confirmed so far. Surgical specimens of Graves' and Hashimoto's diseases and nodular goitres were included in the study. The expression of EBV latent membrane protein 1 (LMP1) was analysed by immunohistochemistry, with the parallel detection of virus-encoded small nuclear non-polyadenylated RNAs (EBER) by in situ hybridisation. In none of the Graves' disease specimens but in 34.5% of Hashimoto's thyroiditis cases the cytoplasmic expression of LMP1 was detected in follicular epithelial cells and in infiltrating lymphocytes. EBER nuclear expression was detected in 80.7% of Hashimoto's thyroiditis cases and 62.5% of Graves' disease cases, with positive correlation between LMP1 and EBER positivity in all Hashimoto's thyroiditis LMP1-positive cases. We assume that high prevalence of EBV infection in cases of Hashimoto's and Graves' diseases imply a potential aetiological role of EBV in autoimmune thyroiditis. The initiation of autoimmune thyroiditis could start with EBV latency type III infection of follicular epithelium characterised by LMP1 expression involving the production of inflammatory mediators leading to recruitment of lymphocytes. The EBV positivity of the infiltrating lymphocytes could be only the presentation of a carrier state, but in cases with EBER+/ LMP1+ lymphocytes (transforming latent infection) it could represent a negative prognostic marker pointing to a higher risk of primary thyroid lymphoma development.

To diagnosis and understand the pathophysiologic status of thyroid disease, not only hormonal measurements but also thyroid scan is believed to have a unique role. Especially in the cases of the change of the thyroid function by thyroiditis, it is emphasized that thyroid scan can be helpful in differential diagnosis, Discordant results of thyroid hormone levels and thyroid scan are found in transient hyperthyroidism, or in transient hypothyroidism. We analysed and reevaluated thyroid scan to look at the importance of thyroid scan. The results are summarised as follows: 1) 80%. of hyperthyroid patients had hyperthyroidism increased RAIU with even density, they are compatible with Graves' disease. 2) 2.1% of hyperthyroid patients had normal or decreased RAIU, which are classified as high iodine turn over genuine hyperthyroidism. 3) 8.5% of hyperthyroid patients had markedly decreased RAIU at both 2 hour and 24 hour, whose pathologic processes are suggested to be heterogenous namely subacute thyroiditis, postpartum thyroiditis, Hashimoto's thyroiditis, and pamless thyroiditis. 4) 45% of hypothyroid patients had increased 24 hr RAIU, 30% of hypothyroid patients were normal, 25%, decreased. In conclusion, thyroid scan should be reevaluated its useful role to asses the pathophysiologic status of thyroid disease. Especially in cases of transient thyrotoxicosis, thyroid scan is essential to diagnose and follow up the disease process.

Background Hashimoto's encephalopathy (HE) is a rare immune-mediated encephalopathy associated with autoimmune Hashimoto's thyroiditis. Objectives and Methods We report on a patient with HE and significant clinical improvement correlating with an increase in cerebral blood flow demonstrated by hexamethylpropyleneamine oxime (HMPAO) single-photon emission computed tomography (SPECT). HMPAO-SPECT was performed with 740 MBq of technetium-99m-HMPAO. To demonstrate the improvement in regional cerebral blood flow, individual regions of interest were drawn around visually diminished HMPAO uptake, the lesion to reference region ratio was calculated and transverse section images and semi-quantitative measurements were performed. Results We show a 5-year follow-up with significant clinical improvement, a 10-fold reduction in autoantibodies to thyroid peroxidase and an approximately 20% improvement in cerebral blood flow with HMPAO-SPECT. Conclusion Adequate levothyroxine treatment achieving and maintaining euthyroidism should be considered as therapy to lower autoantibodies and improve clinical outcome in patients with Hashimoto's thyroiditis and encephalopathy.

This study was designed to investigate the clinical value of serum thyroglobulin (Tg) and antithyroglobulin antibody (TgAb) measurements and the cutoff value after ablation in differentiated thyroid carcinoma (DTC) complicated by Hashimoto thyroiditis (HT) with metastasis. We measured serum Tg and TgAb levels and evaluated the disease status in 164 cases of DTC coexistent with HT in pathologically confirmed patients after surgery and post-remnant ablation during a 3-year follow-up. All Tg and TgAb levels were assessed by chemiluminescent immunoassay (IMA). Receiver operating characteristic (ROC) curve analysis was used to evaluate the prognostic value of Tg and TgAb for disease metastasis. The relationship between Tg and TgAb was analyzed using the scatter diagram distribution method. We found that the cutoff values of Tg and TgAb were 1.48 µg/L and 45 kIU/L, respectively. The area under the ROC curve (AUC) of Tg and TgAb was 0.907 and 0.650, respectively. In DTC coexistent with HT patients, the optimal cutoff value correlated with metastasis in Tg and TgAb was 1.48 µg/L and 45 kIU/L, respectively.

Background In recent years, some reports have suggested that papillary thyroid cancers are more frequently associated with lymphocytic thyroiditis or Hashimoto's thyroiditis. This study investigated a potential increase in the prevalence of chronic lymphocytic thyroiditis among papillary thyroid cancer patients. Materials and Methods We used national epidemiological survey data on thyroid cancer patients diagnosed in 1999, 2005, and 2008. A retrospective medical record survey was conducted by representative sampling of a national cancer incidence database. The analysis included 5,378 papillary thyroid cancer patients aged 20–79 years. We calculated the age-standardized prevalence and age-adjusted prevalence ratios using a binomial regression model with a log link for the prevalence of chronic lymphocytic thyroiditis among papillary thyroid cancer patients by sex for each year. Results The prevalence of chronic lymphocytic thyroiditis among papillary thyroid cancer patients was 4.0% and 12.8% for men and women in 1999, 6.5% and 24.6% in 2005, and 10.7% and 27.6% in 2008, respectively. Between 1999 and 2008, the age-standardized prevalence of chronic lymphocytic thyroiditis increased 4.1-fold in male patients and 2.0-fold in female patients with papillary thyroid cancer. The prevalence of other thyroid diseases, however, did not increase in either gender. Conclusions Among Korean papillary thyroid cancer patients, the prevalence of chronic lymphocytic thyroiditis increased between 1999 and 2008, whereas the prevalence of other thyroid disorders did not change.

In order to evaluate the significance of thyrotropin-binding inhibiting immunoglobulin (TBII) in the patients with autoimmune thyroid diseases, the authors investigated 402 cases of Graves' disease and 230 cases of Hashimoto's thyroiditis comparing 30 cases of normal healthy adult at Kyung Pook University Hospital from February 1993 to August 1994. The TBII was tested by radioimmunoassay and assessed on the dynamic change with the disease course, thyroid functional parameters, and other thyroid autoantibodies; antithyroglobulin antibody(ATAb) and antimicrosomal antibody(AMAb) including thyroglobulin. The serum level of TBII was 40.82 ± 21.651(mean ± SD)% in hyperthyroid Graves' disease and 8.89 ± 14.522% in Hashimoto's thyroiditis and both were significant different from normal control of which was 3.21 ± 2.571%. The frequency of abnormally increased TBII level was 92.2% in hyperthyroid Craves' disease, 46.7% in euthyroid Graves' disease or remission state of hyperthyroidism, and 23.9% in Hashimoto's thyroiditis. The serum levels of increased TBII in Graves' disease were positively correlated with RAIU, serum T3, T4, and FT4, but negatively correlated with serum TSH(each p<0.001). The TBII in Graves' disease had significant positive correlation with serum thyroglobulin and AMAb, but no significant correlation with ATAb. In the Hashimoto's thyroiditis, the serum levels of TBII were positively correlated with RAIU, serum T3, TSH and AMAb, but not significantly correlated with serum T4, FT4, thyroglobulin and ATAb. Therefore serum level of TBII seemed to be a useful mean of assessing the degree of hyperthyroidism in Graves' disease and correlated well with thyroidal stimulation. The serum level of TBII in Hashimoto's thyroiditis is meaningful for the degree of both functional abnormality reflecting either hyperfunction or hypofunction and the immunologic abnormality.

Natural killer (NK) cells serve as primary immune surveillance and are partially regulated by combinations of killer immunoglobulin-like receptors (KIR) and their human leukocyte antigen-C (HLA-C) ligands. Alterations in NK cell activity have been associated with Hashimoto thyroiditis (HT). The aim of this study was to determine whether certain KIR/HLA-C genotype combinations play a role in HT pathogenesis. The present study enrolled 107 unrelated HT patients and 108 random healthy individuals in a case-control study. Blood was collected for DNA extraction; typing of KIR genes and HLA-C alleles was performed by polymerase chain reaction with sequence specific primers (PCR-SSP), followed by electrophoresis on agarose gels. Among a panel of KIR2D/HLA-C genotype combinations, the frequency of KIR2DS2/HLA-C1 was significantly increased in HT patients compared to controls (33.64% vs. 12.96%, PHashimoto thyroiditis KIR = killer immunoglobulin-like receptor NK = natural killer PCR = polymerase chain reaction.

Objective: To investigate the clinical value of quantitative 99 Tc m -pertechnetate thyroid imaging for the diagnosis and therapeutic evaluation in patients with thyroid disease. Methods: With the Siemens Orbit SPECT, 99 Tc m sodium pertechnetate thyroid imaging was performed on a control group and 108 patients with Graves' disease, 58 patients with Hashimoto's disease, 41 patients with subacute thyroiditis. Three functional parameters were calculated as follows: AR=5 min thyroid count/1 min thyroid count; UI=20 min thyroid count/thigh count; T d =imaging interval between carotid and thyroid. Results: 1) Three functional parameters were basically concordant with serological parameters in patients with Graves' disease. While uptake was high in patients who had contracted Graves' disease for ≤0.5 year, for those whose disease relapsed within 2 years the 99 Tc m thyroid uptake increased when the antithyroid medication was stopped. 2) Thyroid images of hyperthyroid patients with Hashimoto's disease showed increased perfusion and 99 Tc m uptake, a pattern similar to that found in Graves' disease. Differences in T d , AR , UI were not significant among euthyroid, subclinical hypothyroid patients with Hashimoto's disease, so uptake ratios could indicate the thyroid activity. 3) Delayed thyroid image and diffuse uptake decrease were found in hyperthyroid patients with SAT, however, focal damages were observed in euthyroid patients. Conclusion: Quantitative 99 Tc m -pertechnetate thyroid imaging is a significantly helpful technique in the diagnosis and treatment for common thyroid disorders

Aerobic physical exercise in the third trimester in pregnant woman with Hashimoto`s thyroiditis: A case report

Full Text Available Introduction. Physical exercise and thyroid function affect the course and outcome of pregnancy. Pregnancy conversely has an effect on exercise and the secretion of thyroid hormones. It is recommended that pregnant women without medical or obstetric complications engage in physical exercise, as correct exercise and suitable hormonal therapy reduce the risk of a negative course and outcome of the pregnancy. Case report. A 33- year-old marathon runner with diagnosed Hashimoto’s thyroiditis continued to run until she was ready to give birth. The recorded parameters were body mass, and scope and intensity of running. In the third trimester, additional recorded parameters were blood pressure, pulse, blood glucose, prolactin, cortisol and thyroid hormones [thyroxine (T4 and thyroid-stimulating hormone (TSH]. Foetus growth and development, as well as the status of the subject’s health, were monitored at regular endocrinological and gynaecological examinations. There was an expected increase in body mass during pregnancy, which resulted in a reduction in the running distance and intensity. TSH, cortisol and prolactin blood levels were increased. Statistically, significant correlation has been obtained between TSH and the intensity of running (r = 0.864; p = 0.027. Using the method of cardiotocography (CTG, the average pulse rate in the lower reference range has been recorded (118 bpm. The delivery was induced at the scheduled date. There were no complications in the course and outcome of the pregnancy. Conclusion. Moderate to light aerobic physical exercise had no negative effect on the course and the outcome of the pregnancy in the subject with Hashimoto’s thyroiditis.

Abstract This study aims to investigate the impact of psammoma body (PB) on papillary thyroid carcinoma (PTC), and evaluate the association among PB, Hashimoto thyroiditis (HT), and other clinicopathologic characteristics in PTC patients. We conducted a retrospective case-control study involving 1052 PTC patients who underwent total thyroidectomy or lobectomy with lymph node dissection. Psammoma body was observed in 324 out of 1052 PTC (30.8%) patients. Ultrasonographic (US) calcification (P < 0.001), multifocality of the tumor (P = 0.047), lymph node metastasis (LNM) (P < 0.001), HT (P < 0.001), and Primary tumor (T), Regional lymph nodes (N), Distant metastasis (M) staging (P = 0.001) were significantly related to the presence of PB. The presence of PB was significantly associated with US microcalcification (P < 0.001). In the subgroup with HT, compared with the patients without PB, the patients with PB exhibited a higher frequency of central LNM (54.7% vs 32.1%; P < 0.001) and US microcalcification (94.7% vs 38.8%; P < 0.001), as well as smaller tumors (0.9 ± 0.6 vs 1.3 ± 0.9 cm; P < 0.001). In the subgroup without HT, the patients with PB displayed a higher incidence of lateral LNM (25.8% vs 14.6%; P < 0.001), US microcalcification (87.3% vs 52.5%; P < 0.001), and extrathyroidal extension (47.2% vs 34.8%; P = 0.001), as well as larger tumors (1.3 ± 0.9 vs 1.0 ± 0.8 cm; P < 0.001) than without PB. Moreover, in the subgroup with PB, the PTC patients with HT showed a higher LNM (77.9% vs 57.2%; P < 0.001) and a lower frequency of extrathyroidal extension (20.0% vs 47.2%; P < 0.001) than without HT. Psammoma body is a useful predictor of aggressive tumor behavior in PTC patients. HT with PB shows more aggressive behaviors than non-HT with PB in PTC patients. PMID:26554782

Although Sjös syndrome (SS) is the most common disease causing xerostomia, autoimmune thyroid diseases can also affect the salivary glands. The aim of our study was to estimate the prevalence of thyroid diseases (TD) in subjects with symptoms of xerostomia and evaluate the efficacy of salivary gland scintigraphy (SGS) in the detection of TD in patients with SS and without SS. We retrospectively reviewed the SGS findings of 173 subjects (men:women, 29:144) with symptoms of xerostomia. Ejection fractions (EF) in the parotid and submandibular glands were calculated. Thyroid disease was diagnosed on the basis of the results of the visual assessment of tracer uptake in the thyroid gland on SGS images as well as serological thyroid function tests. Based on the American-European Criteria, 94 patients were diagnosed with SS. Hashimoto's thyroiditis was diagnosed in 63 patients, subacute thyroiditis in 23, subclinical hypothyroidism in five, and Graves' disease in one. There were significant differences in the EF values of the parotid and submandibular glands between patients with TD and those with undetermined diagnoses. More than half of patients with xerostomia exhibited TD. Thyroid assessment by SGS is feasible, and SGS appears to be useful for the patients with xerostomia caused by TD. SGS may be the first imaging modality capable of evaluating both salivary gland function and thyroid gland status in patients with xerostomia. This strategy would make the requirement for additional workup for thyroid disease.

Full Text Available Abstract Background Three genes have been confirmed as major joint susceptibility genes for endocrine autoimmune disease:human leukocyte antigen class II, cytotoxic T-lymphocyte antigen 4 and protein tyrosine phosphatase non-receptor type 22. Recent studies showed that a genetic variation within the interferon induced helicase domain 1 (IFIH1 locus (rs1990760 polymorphism is an additional risk factor in type 1 diabetes and Graves' disease (GD. Methods The aim of the present study was to investigate the role of the rs1990760 polymorphism within the IFIH1 gene in German patients with GD (n = 258, Hashimoto's thyroiditis (HT, n = 106, Addison's disease (AD, n = 195 and healthy controls (HC, n = 227 as well as in 55 GD families (165 individuals, German and 100 HT families (300 individuals, Italian. Furthermore, the interaction between rs1990760 polymorphism with human leukocyte antigen (HLA risk haplotype DQ2(DQA*0501-DQB*0201, the risk haplotypes DQ2/DQ8 (DQA*0301-DQB*0302 and the status of thyroglobulin antibody (TgAb, thyroid peroxidase antibody (TPOAb and TSH receptor antibody (TRAb in patients and families were analysed. Results No significant differences were found between the allele and genotype frequencies for rs1990760 IFIH1 polymorphism in patients with GD, HT, AD and HC. Also no differences were observed when stratifying the IFIH1 rs1990760 polymorphism for gender, presence or absence of thyroid antibodies (GD:TRAb and HT:TPOAb/TgAb and HLA risk haplotypes (DQ2:for GD and HT, DQ2/DQ8:for AD. Furthermore the transmission analysis in GD and HT families revealed no differences in alleles transmission for rs1990760 IFIH1 from parents with or without HLA risk haplotype DQ2 to the affected offspring. In contrast, by dividing the HT parents according to the presence or absence of thyroid Ab titers, mothers and fathers both positive for TPOAb/TgAb overtransmitted the allele A of IFIH1 rs1990760 to their HT affected offspring (61.8% vs 38.2%;p = 0

Background: Autoimmune hypothyroidism (Hashimoto thyroiditis; HT) is the most common postnatal thyroid disease. Clinical manifestations of HT vary according to disease severity. Due to the pleiotropic effects of thyroid hormone, less common signs and symptoms of HT can occur, leading to a delay in diagnosis. Case presentation: A 9-year-old girl of Indian origin was admitted for a one-week history of widespread myalgia, fatigue, muscle weakness, difficulty walking, and a significant increase in weight (approximately 2 kg) without any changes in daily habits.

Full Text Available Background: Autoimmune hypothyroidism (Hashimoto thyroiditis; HT is the most common postnatal thyroid disease. Clinical manifestations of HT vary according to disease severity. Due to the pleiotropic effects of thyroid hormone, less common signs and symptoms of HT can occur, leading to a delay in diagnosis. Case presentation: A 9-year-old girl of Indian origin was admitted for a one-week history of widespread myalgia, fatigue, muscle weakness, difficulty walking, and a significant increase in weight (approximately 2 kg without any changes in daily habits. The only relevant medical history was several intermittent vaginal bleeding episodes since four years of age. Breast development was consistent with Tanner stage 2 without pubic or axillary hair; while height and weight were at the 10th percentile and the 38th percentile; respectively. Bone age from a left wrist X-ray was delayed 1 year. Pelvic ultrasonography revealed a uterine body/neck ratio of >1 (pubertal stage and multifollicular ovaries.

We examined fifteen cases with focal fluorodeoxyglucose (FDG) uptake in the thyroid gland detected by FDG-positron emission tomography (PET) screening for cancer. Examination of the thyroid gland was carried out by using computer tomography, ultrasound sonography, laboratory test and fine needle aspiration cytology (FNAC). Surgical operation was performed to the patient who was suspected of having thyroid cancer by FNAC or clinical findings. Thyroid cancer was histologically confirmed in 4 cases. Malignancy was not ruled out by FNAC in one patient. Seven patients were suspected of having benign thyroid tumor (adenoma, adenomatous goiter). Three patients were diagnosed with thyroiditis (Hashimoto thyroiditis, subacute thyroiditis, painless thyroiditis) by laboratory tests. It was not easy to differentiate between cancer and benign diseases only by FDG-PET. However, it was useful to detect thyroid tumor especially if the tumor is hardly palpable. FDG-PET was also valuable as a diagnostic imaging technique to evaluate metastasis and the extent of cancer. (author)

This study aimed to assess the relationship between coexisting lymphocytic thyroiditis and T-N stages of papillary thyroid carcinoma (PTC) by histopathological analysis. The study included 653 patients who underwent thyroid surgery for PTC at our hospital. Each case was classified as either Hashimoto's thyroiditis (HT), non-Hashimoto type of lymphocytic thyroiditis (NHLT), or normal according to the histopathology of thyroid parenchyma. Patient age, gender, surgical modality, location, T stage, N stage, multifocality and bilaterality were compared according to the histopathology. The prevalence of coexisting lymphocytic thyroiditis was 25.8% (169/653); HT (7.5%, 49/653) and NHLT (18.3%, 120/653). There were no significant differences in T stage, N stage, multifocality and bilaterality with regard to coexisting lymphocytic thyroiditis, regardless of whether HT and NHLT were considered collectively or discretely. Primary tumor size (p thyroiditis did not differ from those with normal parenchyma in terms of T stage, N stage, multifocality and bilaterality.

Ultrasound examination of the thyroid offers an accurate morphological picture and the possibility of comparing objectively the size of lobes and lesions over long periods. Cysts and calcifications, mostly benign, are readily recognized. Neoplastic lesions in our series were all less reflective than normal thyroid tissue. But so were the majority of benign nodules. In hyperthyroidism, subacute thyroiditis and Hashimoto's thyroiditis, the thyroid tissue is much less echogenic than in the normal gland.

We review here 3 cases of primary thyroid lymphoma that we experienced during the past 5 years (age range: 39-55, all of the patients were female). The clinical and various ultrasonographic characteristics together with the other imaging modalities of primary thyroid lymphomas are described. The clinical features at presentation for one patient were a goiter with rapid growth and this was accompanied by compressive symptoms. The tumors of the other 2 patients were incidentally found during screening thyroid ultrasound exams. The pathologic studies of 2 cases showed a diffuse B-cell lymphoma with associated Hashimoto's thyroiditis and one case was a B-cell lymphoma of the MALT type. An extra-thyroid extension was shown in one case. The treatments included surgery alone for two cases, and chemotherapy and radiation therapy for one case. A US exam of thyroid lymphoma can show various morphological features, and US-CNB is helpful for diagnosing thyroid lymphoma.

2016-08-01

The present study aimed to report the shear wave elastography (SWE) findings in a patient with the diffuse sclerosing variant of papillary thyroid carcinoma (DSVPTC). Since patients with DSVPTC may present with typical clinicopathological features and initially appear to have Hashimoto's thyroiditis, a thorough clinical evaluation and an early diagnosis are important. A 20-year-old female patient presented with a 1-month history of a neck mass and sore throat. Conventional ultrasound and SWE were performed using an AIXPLORER system with 14-5 MHz linear transducer. The patient had undergone total thyroidectomy and bilateral neck lymph node dissection, and an intraoperative pathology consultation to confirm the malignancy of lymph node metastasis. Pathological diagnosis was DSVPTC in both lobes, with lymph node metastases in the bilateral neck. The clinical presentation and serological findings were all indicative of Hashimoto's thyroiditis. Thyroid ultrasonography revealed diffuse enlargement of the both lobes, heterogenous echogenicity without mass formation, diffuse scattered microcalcifications and poor vascularization. SWE revealed stiff values of the thyroid: The mean stiffness was 99.7 kpa, the minimum stiffness was 59.1 kpa and the maximum stiffness was 180.1 kpa. The maximum stiffness of the DSVPTC (180.1 kpa) was higher compared with the diagnostic criteria of malignant thyroid nodules (65 kPa). SWE may be considered as a novel and valuable method to diagnose DSVPC.

This study aimed to evaluate 8-OHdG and hypoxia-inducible factor 1 (HIF-1α) levels in patients with hypoactive thyroid nodules (toxic multi-nodular goiter, Graves' disease, and Hashimoto's thyroiditis), as these parameters may be related to oxidative stress and the pathogenesis of cancer. The study included patients diagnosed with Graves' disease (n = 20), toxic multinodular goiter (n = 20), and Hashimoto thyroiditis (n = 20), and 20 healthy controls. HIF-1α levels were measured in blood samples and 8-OHdG levels were measured in urine - both via ELISA. HIF-1α and 8-OHdG levels were significantly higher in the patient groups than in the control group (p 0.05). There was no significant difference in 8-OHdG or HIF-1α levels between the patients with biopsy results that were benign, malignant, and non-diagnostic (p > 0.05). Serum HIF-1α and urine 8-OHdG levels were significantly higher in the patients with thyroid diseases; however, a relationship with cancer was not observed.

Hashimoto's encephalopathy (HE) is a rare not well understood, progressive and relapsing multiform disease, characterized by seizures, movement disorders, subacute cognitive dysfunction, psychiatric symptoms and responsiveness to steroid therapy. The disorder is generally associated with thyroid ...... diseases and the most common feature is the presence of anti-thyroperoxidase antibodies (TPOAb). Patients are usually euthyroid or mildly hypothyroid at presentation. All age groups can be affected. The pathophysiology is still unclear, especially the link between elevated serum TPOAb...... and the encephalopathy. Most reported cases occurred in women and girls. Unspecific symptoms, non-pathognomonic laboratory neurophysiology and neuroimaging features make its diagnosis a real challenge for clinicians.The case of a 16 year old boy, with a clinical picture of HE associated with hypothyroidism...

Full Text Available Aspects of autoimmune thyroid disease updated in this review include: immunoglobulin G4 (IgG4-related thyroid disease (Riedel's thyroiditis, fibrosing variant of Hashimoto's thyroiditis, IgG4-related Hashimoto's thyroiditis, and Graves' disease with elevated IgG4 levels; recent epidemiological studies from China and Denmark indicating that excess iodine increases the incidence of Hashimoto's thyroiditis and hypothyroidism; immunomodulatory agents (ipilimumab, pembrolizumab, nivolumab activate immune response by inhibiting T-cell surface receptors which down-regulate immune response, i.e., cytotoxic T-lymphocyte antigen 4 and programmed cell death protein 1 pathways; alemtuzumab is a humanised monoclonal antibody to CD52 which causes immune depletion and thyroid autoimmune disease especially Graves' hyperthyroidism; small molecule ligand (SML agonists which activate receptors, SML neutral antagonists, which inhibit receptor activation by agonists, and SML inverse agonists which inhibit receptor activation by agonists and inhibit constitutive agonist independent signaling have been identified. SML antagonism of thyroid-stimulating hormone-receptor stimulatory antibody could treat Graves' hyperthyroidism and Graves' ophthalmopathy; and thyroxine treatment of subclinical hypothyroidism can produce iatrogenic subclinical hyperthyroidism with the risk of atrial fibrillation and osteoporosis. The increased risk of harm from subclinical hyperthyroidism may be stronger than the potential benefit from treatment of subclinical hypothyroidism.

[Thyroid echogeneity as a useful tool for the differential diagnosis of hyperthyroidism in the course of Graves disease and Hashimoto thyroiditis].

Hashimoto's thyroiditis (HT) and Graves' disease (GD) constitute a spectrum of autoimmune thyroid diseases (AITD). They share an autoimmune pathogenesis, with a cellular and a humoral response to the thyroid gland. As a consequence, dysfunction of the gland itself may develop, characterized by hyperfunction in the case of GD and hypofunction in the case of HT, however at the onset of HT the hyperthyroidism might be observed as a result of a rapid destruction of thyrocytes. An abnormal thyroid echographic pattern characterized by a diffuse low echogeneity has been described in both AITD. This hypoechogeneity is due to three components: increase of intrathyroidal flow, functional changes in thyroid follicles with increased cellularity and decrease of the colloid content, resulting in the reduction of the cell/colloid interface, variable degree of lymphocytic infiltration. The first two components may be reversible during medical treatment and seem to be characteristic for GD, whereas lymphocytic infiltration may rather represent mostly HT. Here we present a 17-year-old girl with typical clinical signs of hyperthyroidism [firm goiter (II degrees), tachycardia, palpitations, nervousness, excessive sweating and tremor]. Laboratory tests were the following: fT3 - 6.59 pg/ml(increasing), fT4 - 1.99 ng/dl(increasing), TSH - 0.02 micro IU/ml(decreasing); anti-Tg-Ab - 840 IU/ml(increasing), anti-TPO-Ab - 190 IU/ml(increasing) (4 months later antithyroid antibodies were 2200 and 70, respectively). Ultrasound examination showed hypoechogeneity of the whole gland and enhanced vascular flow based on power Doppler analysis. Thyroid scan visualized the generally increased uptake of technetium. The girl was put on beta-blocker (propranolol) and later an antithyroid drug (thiamazole) was added. A course of disease was unstable, therefore the fine-needle aspiration biopsy was performed and showed the presence of single groups of normal thyrocytes and scanty colloid with no features

Early histological changes in the thyroid gland were examined in 30 patients with juvenile thyrotoxicosis, by means of needle biopsy. Based on the degree of lymphocytic infiltration and degenerative changes in follicular epithelium, results were classified into four groups. A: hyperplastic changes without cellular infiltration (6 patients, 20%); B: hyperplastic changes with areas of focal thyroiditis less than 30% of specimen (10 patients, 33%); C: those with 30 to 60% areas ot thyroiditis (10 patients, 33%); D: almost diffuse thyroiditis (4 patients, 13%). Moderate to severe lymphocytic thyroiditis was frequently present in the early stage of hyperplastic thyroid glands. The clinical significance of the 4 histological groups was evaluated. Neither clinical signs nor routine laboratory tests could differentiate these groups except group D, in which thyrotoxic signs were mild and transient. However, serum antithyroid antibodies tended to increase in accordance with severity of thyroiditis. The rate of remission was high in groups C and D, whereas relapse was frequent in group A. These results suggest that Grave's disease and chronic lymphocytic thyroiditis are closely related in the early stage of thyrotoxicosis in children, and that the clinical course may be considerably altered by the degree of associated thyroiditis.

The optimal utilization of the thyroid related radioimmunoassays T3, T4, and TSH-RIA is derived from analysing the clinical and laboratory data for 974 patients with functional thyroid disorders. A statistical computer analysis of the contribution of each of the three tests, and in combination, to the final diagnoses of hypothyroid, euthyroid, and hyper thyroid states was designed. The best contributing test for hypothyroidism and euthyroidism was TSH-RIA (98.5 and 93%, respectively). T4/T3+TSH-RIAs were the optimal dual combination for diagnosing euthyroidism (98.0%). For diagnosing hyperthyroidism T4-RIA was the best single test (82.5%) followed by T3 + T4 as an optimal dual combination (95%). Using all three tests was of no significant additional value over dual combinations. It is concluded that the work and cost of randomly performing three tests routinely is not justified without clinical basis. An algorithm is proposed to guide thyroid studies based on computer analyses of the above-mentioned single or dual-test combinations to establish accurate diagnosis at the lowest laboratory cost.

Th primary thyroid lymphoma is a rare neoplasm, above all in children. We present a case of a child with Burkitt's thyroid lymphoma as the only manifestation of this disease, associated to lymphocytic thyroiditis. Clinically, it initiated as a rapidly growing goiter with compressive symptomatology. The X-ray findings are described: hypoechoic and hypodense multiple nodes that affect the right thyroid lobe and isthmus, with extraglandular extension to the vascular space and to the mediastinum. The differential diagnosis is considered with other more frequent thyroid pathologies in this age group. (Author) 14 refs.

To evaluate in a cohort of 100 consecutive patients affected by primary Sjogren's syndrome (pSS) the incidence of Hashimoto thyroiditis (HT) and to compare the clinical features and the laboratory parameters of patients affected by pSS with and without concomitant HT. In 100 consecutive patients affected by pSS, the occurrence of other autoimmune diseases was recorded and a full examination of thyroid function obtained. HT was associated with pSS in 27 cases. The comparison between pSS cases with and without HT showed that only patients with isolated pSS had low C4 level [p = 0.032, OR (IC 95 %) 230 (13.13-4,046)]. In addition, only patients affected by pSS without HT had evidence of cryoglobulins, cutaneous vasculitis with palpable purpura, peripheral neuropathy, and development of lymphoma, although all these manifestations were observed in a 4.1-8.2 % of the cases, without reaching statistical significance. The association of HT in patients suffering from pSS defines a subset of patients with milder disease and normal C4 levels.

We present a case of a 30-year-old woman diagnosed with arterial hypertension in the 25th week of pregnancy. Our search for secondary causes of arterial hypertension revealed hyperthyroid Hashimoto's thyroiditis (HT), which was treated with propilthiouracil. Three weeks after delivery, she was normotensive without medication. In the next four months, she developed hypothyroidism and treatment with L-thyroxine was started. In conclusion, in the second half of pregnancy, a hyperthyroid HT can occur - in spite of the well-known amelioration of autoimmune thyroid disorders in that period, and can be the only cause of arterial hypertension.

Contactin-associated protein 2 (Caspr2) antibody is a neuronal surface antibody (NSAb) capable of causing disorders involving central and peripheral nervous systems (PNS). Thymoma can be found in patients with Caspr2 antibodies and is most frequently associated with PNS symptoms. Myasthenia gravis can be found in these patients, but Hashimoto thyroiditis (HT) has not been reported. A 76-year-old woman presented with sub-acute-onset changes in mental status. Further investigations revealed thymoma and HT. The presence of NSAb was tested by immunofluorescence on human embryonic kidney-293 cells. Treatment included corticosteroids, azathioprine, thyroxine, plasmapheresis, and thymectomy. Caspr2 antibody was positive in serum but absent in CSF. Brain magnetic resonance imaging (MRI) showed diffuse cortical atrophy, but did not change significantly after treatments. Brain positron emission tomography (PET) revealed diffuse hypometabolism over the cerebral cortex. The patient's mental status only partially improved. In Caspr2 antibody-associated syndromes, thymoma can occur in patients presenting only with LE, and HT can be an accompanying disease. Brain MRI and PET may not show specific lesions in limbic area. Patients with Caspr2 antibodies and thymoma may not have good prognosis. Copyright © 2014 Elsevier B.V. All rights reserved.

Peroxisome proliferator-activated receptor γ (PPARγ) is a transcription factor that regulates the expression of multiple target genes involved in several metabolic pathways as well as in inflammation. The expression and cell localization of caveolin-1 (Cav-1), thyroperoxidase (TPO), and dual oxidase (DUOX), involved in extracellular iodination, is modulated by Th1 cytokines in human normal thyroid cells and in Hashimoto's thyroiditis (HT). The objectives of this study were (i) to analyze the PPARγ protein and mRNA expression at the follicular level in HT versus controls in correlation with the one of Cav-1; (ii) to study the effects of Th1 cytokines on PPARγ and catalase expression in human thyrocyte primary cultures; and (iii) to study the effects of pioglitazone, a PPARγ agonist, on thyroxisome components (Cav-1, TPO, DUOX) and on catalase, involved in antioxidant defense. Although the global expression of PPARγ in the whole gland of patients with HT was not modified compared with controls, there was great heterogeneity among glands and among follicles within the same thyroid. Besides normal (type 1) follicles, there were around inflammatory zones, hyperactive (type 2) follicles with high PPARγ and Cav-1 expression, and inactive (type 3) follicles which were unable to form thyroxine and did not express PPARγ or Cav-1. In human thyrocytes in primary culture, Th1 cytokines decreased PPARγ and catalase expression; pioglitazone increased Cav-1, TPO, and catalase expression. PPARγ may play a central role in normal thyroid physiology by upregulating Cav-1, essential for the organization of the thyroxisome and extracellular iodination. By upregulating catalase, PPARγ may also contribute to cell homeostasis. The inhibitory effect of Th1 cytokines on PPARγ expression may be considered as a new pathogenetic mechanism for HT, and the use of PPARγ agonists could open a new therapeutic approach.

Clinical Relevance of Environmental Factors in the Pathogenesis of Autoimmune Thyroid Disease

Full Text Available Genetic factors contribute for about 70% to 80% and environmental factors for about 20% to 30% to the pathogenesis of autoimmune thyroid disease (AITD. Relatives of AITD patients carry a risk to contract AITD themselves. The 5-year risk can be quantified by the so-called Thyroid Events Amsterdam-score, based on serum thyroid-stimulating hormone, thyroid peroxidase (TPO-antibodies and family history. Subjects at risk may ask what they can do to prevent development of AITD. This review summarizes what is known about modulation of exposure to environmental factors in terms of AITD prevention. To stop smoking decreases the risk on Graves disease but increases the risk on Hashimoto disease. Moderate alcohol intake provides some protection against both Graves and Hashimoto disease. Low selenium intake is associated with a higher prevalence of thyroid autoimmunity, but evidence that selenium supplementation may lower TPO antibodies and prevent subclinical hypothyroidism remains inconclusive. Low serum vitamin D levels are associated with a higher prevalence of TPO antibodies, but intervention studies with extra vitamin D have not been done yet. Stress may provoke Graves hyperthyroidism but not Hashimoto thyroiditis. Estrogen use have been linked to a lower prevalence of Graves disease. The postpartum period is associated with an increased risk of AITD. Taking together, preventive interventions to diminish the risk of AITD are few, not always feasible, and probably of limited efficacy.

Traditionally, thyroid imaging has been performed primarily using radionuclide scanning. High-resolution computed tomography (CT) was performed in 18 patients to evaluate the CT appearance of various thyroid abnormalities including diffuse toxic goiter, multinodular goiter, Hashimoto thyroiditis, thyroid adenoma, and malignant thyroid tumors. CT images of the thyroid were correlated with radionuclide scanning, surgical findings, and clinical and laboratory results. CT provided a complementary method for evaluation of the thyroid by defining the morphology of the thyroid gland and more precisely defining the anatomic extent of thyroid abnormalities in relation to the normal structures of the neck and mediastinum

Interactions between cytokines and others soluble factors (hormones, antibodies...) can play an important role in the development of thyroid pathogenesis. The purpose of the present study was to examine the possible correlation between serum cytokine concentrations, thyroid hormones (FT4 and TSH) and auto-antibodies (Tg and TPO), and their usefulness in discriminating between different thyroid conditions. In this study, we investigated serum from 115 patients affected with a variety of thyroid conditions (44 Graves' disease, 17 Hashimoto's thyroiditis, 11 atrophic thyroiditis, 28 thyroid nodular goitre and 15 papillary thyroid cancer), and 30 controls. Levels of 17 cytokines in serum samples were measured simultaneously using a multiplexed human cytokine assay. Thyroid hormones and auto-antibodies were measured using ELISA. Our study showed that IL-1β serum concentrations allow the discrimination between atrophic thyroiditis and papillary thyroid cancer groups (p = 0.027).

The subjects were 229 patients with 253 normal thyroid lobes (controls and 150 CAT lobes. The SWV for CAT (2.47 ± 0.57 m/s was significantly higher than that for controls (1.59 ± 0.41 m/s (P<0.001. The area under the receiver operating characteristics (ROC curve for CAT was 0.899, and the SWV cut-off value was 1.96 m/s. The sensitivity, specificity, and diagnostic accuracy were 87.4%, 78.7%, and 85.1%, respectively. Levels of anti-thyroperoxidase antibodies and thyroid isthmus thickness were correlated with tissue stiffness in CAT. However, there was no correlation between levels of anti-thyroglobulin antibodies and tissue stiffness. Quantitative SWE is useful for diagnosing CAT, and it is possible that SWE can be used to evaluate the degree of fibrosis in patients with CAT.

Autoimmune thyroid diseases (AITD) are postulated to develop as a result of a complex interplay between several genetic and environmental influences. The pathogenesis of AITD is still not clearly defined. However, among the implicated triggers (e.g. iodine, infections, medications), more recent data confirmed strong associations of AITD with the hepatitis C virus (HCV) infection and interferon-α (IFNα) therapy. Moreover, it is likely that HCV and IFN act in synergism to trigger AITD in patients. Indeed, approximately 40% of HCV patients develop either clinical or subclinical disease while receiving IFNα. Interferon induced thyroiditis (IIT) can manifest as non-autoimmune thyroiditis (presenting as destructive thyroiditis, or non-autoimmune hypothyroidism), or autoimmune thyroiditis [presenting with clinical features of Graves' disease (GD) or Hashimoto's thyroiditis (HT)]. Although not yet clearly understood, it is thought that IFNα can induce thyroiditis via both immune stimulatory and direct toxic effects on the thyroid. In view of the high frequency of IIT, routine screening and surveillance of HCV patients receiving IFNα is recommended to avoid the complications, such as cardiac arrhythmias, associated with thyrotoxicosis. In summary, IIT is a common clinical problem that can be readily diagnosed with routine thyroid function screening of HCV patients receiving IFN. The treatment of IIT consists of the standard therapy for differing clinical manifestations of IIT such as GD, HT, or destructive thyroiditis. However, anti-thyroid medications are not recommended in this setting since they can potentially be hepatotoxic.

Full Text Available Hashimoto's Thyroiditis (HT is a common organ-specific autoimmune disorder associated with a high incidence, and insulin resistance is highly related to autoimmune. Here, we examined the insulin sensitivity in HT patients and found decreased insulin sensitivity occurred in HT patients. To explore the relationship between impaired insulin sensitivity and immune status, we established HT model mice which showed similar pathological features and immune features to HT patients. In HT model mice, reinfusion of regulatory T cells (Tregs from peripheral blood of normal mice could improve insulin sensitivity and decrease the inflammation. Anti-CD25 antibodies blocked beneficial effects from reinfusion of Tregs, but delayed administration of anti-CD25 antibodies could not abolished the effect from Tregs. Delayed administration of anti-CD25 antibodies abolished exogenous Tregs in peripheral blood, but there were increased exogenous Tregs located to visceral adipose tissues (VATs which modulated the expression of cytokines in VATs. These findings suggest that insulin resistance exists in HT patients and it associates with the decreased Tregs and increased inflammation in the VATs.

Hashimoto thyroiditis (HT) and other benign goiters (BG) might influence patients' quality of life (QoL). The objective of this study was to analyze influence of surgery on these patients' QoL. A prospective cohort study was conducted. The ThyPRO questionnaire was used in the QoL assessment. The HT patients experienced significantly worse hypothyroid symptoms and sex life than the BG patients. The improvement in QoL in the BG patients was significant after surgery in all ThyPRO domains. In the HT patients, the improvement was significant in all but two domains, eye symptoms and cognitive impairment. The best improvement in both groups was in overall QoL. None of the patients developed permanent consequences. The QoL of HT and BG patients is impaired and improves significantly after surgical treatment. Thyroidectomy should be considered as a treatment option in the HT patients more often as in the BG patients. Copyright © 2015 IJS Publishing Group Limited. Published by Elsevier Ltd.

The aim of the study was to evaluate systematic thyroid ultrasonography (US) relevance in newly diagnosed Graves' disease among patients presenting without palpable nodules. We consecutively recruited 208 cases of Graves' disease without palpable nodule. All patients were screened for thyroid antibodies and underwent a thyroid US. Ultrasonically guided biopsy was proposed for the assessment of all nodules upper or equal to 10mm in diameter. Two third of patients had an abnormal thyroid at palpation requiring an US. One third of patients had a normal thyroid at palpation and US was consequently unwarranted. Among all patients, US detected non-palpable nodules in 26% of cases. We found no smears suspected to be cancerous. In newly diagnosed Graves' disease, the US relevance is only questionable in patients without abnormal thyroid at palpation. Ultrasonography detected non-palpable nodules and none was suspected to be cancerous. These data suggest that US is not useful in patients without abnormal thyroid at palpation. Nevertheless, the recent Thyroid Imaging-Reporting And Data System classification (TI-RADS) might change our conclusions. The TI-RADS classification indeed improves the selection of nodules lower than 10mm in diameter requiring a biopsy. Nodules lower than 10mm in diameter were not biopsied in the present study. The other US data presented herein (echogenicity, vascularisation) provide no further relevance for systematic US in newly diagnosed patients. Copyright © 2014 Elsevier Masson SAS.

Thyroid cancer (TC), follicular adenoma (FA) and Hashimoto's thyroiditis (HT) are three of the most frequently reported abnormalities that affect the thyroid gland. A frequent co-occurrence along with similar histopathological features is observed between TC and FA as well as between TC and HT. The conventional diagnostic methods such as histochemical analysis present complications in differential diagnosis when these abnormalities occur simultaneously. Hence, the authors recognize novel methods based on screening genetic defects of thyroid abnormalities as viable diagnostic and prognostic methods that could complement the conventional methods. We have extensively reviewed the existing literature on TC, FA and HT and also on three genes, namely braf, nras and ret/ptc, that could be used to differentially diagnose the three abnormalities. Emphasis was also given to the screening methods available to detect the said molecular markers. It can be conferred from the analysis of the available data that the utilization of braf, nras and ret/ptc as markers for the therapeutic evaluation of FA and HT is debatable. However, molecular screening for braf, nras and ret/ptc mutations proves to be a conclusive method that could be employed to differentially diagnose TC from HT and FA in the instance of a suspected co-occurrence. Thyroid cancer patients can be highly benefited from the screening for the said genetic markers, especially the braf gene due to its diagnostic value as well as due to the availability of personalized medicine targeted specifically for braf mutants.

Thyroid hormones have been shown to be absolutely necessary for early brain development. During pregnancy, both maternal and foetal thyroid hormones contribute to foetal brain development and maternal supply explains why most of the athyreotic newborns usually do not show any signs of hypothyroidism at birth. Foetal and/or neonatal hypothyroidism is a rare disorder. Its incidence, as indicated by neonatal screening, is about 1:4000. Abnormal thyroid development (i.e. agenesia, ectopic gland, hypoplasia) or inborn errors in thyroid hormone biosynthesis are the most common causes of permanent congenital hypothyroidism. Recent studies reported that mutations involving Thyroid Transcriptor Factors (TTF) such as TTF-1, TTF-2, PAX-8 play an important role in altered foetal thyroid development. Deficiency of transcriptor factor (Pit-1, Prop-1, LHX-3) both in mother and in the foetus represents another rare cause of foetal hypothyroidism. At birth clinical picture may be not always so obvious and typical signs appear only after several weeks but a delayed diagnosis could have severe consequences consisting of delayed physical and mental development. Even if substitutive therapy is promptly started some learning difficulties might still arise suggesting that intrauterine adequate levels of thyroid hormones are absolutely necessary for a normal neurological development. Placental transfer of maternal antithyroid antibodies inhibiting fetal thyroid function can cause transient hypothyroidism at birth. If the mother with thyroid autoimmune disease is also hypothyroid during pregnancy and she doesn't receive substitutive therapy, a worse neurological outcome may be expected for her foetus. Foetal and/or neonatal hyperthyroidism is a rare condition and its incidence has been estimated around 1:4000-40000, according to various authors. The most common causes are maternal thyroid autoimmune disorders, such as Graves' disease and Hashimoto's thyroiditis. Rarer non autoimmune causes

Associations between vitiligo and thyroid diseases have been reported repeatedly. We investigated the associations between vitiligo and overt autoimmune thyroid diseases and thyroid cancer using the Korean National Health Insurance claims database. We defined patients with vitiligo as those whose records showed ≥4 physician contacts between 2009 and 2013 in which vitiligo was the principal diagnosis. We also established an age- and sex-matched control group without vitiligo (2 per 1 vitiligo patient). The outcomes of interest were concurrent Graves disease and Hashimoto thyroiditis (the patients were taking relevant thyroid medications) and thyroid cancer. The study enrolled 73,336 vitiligo patients and 146,672 controls. Patients with vitiligo were at increased risks of Graves disease (odds ratio [OR] 2.610 [95% confidence interval {CI} 2.319-02.938]), Hashimoto thyroiditis (OR 1.609 [95% CI 1.437-1.802]), and thyroid cancer (OR 1.127 [95% CI 1.022-1.242]), compared with the controls. The associations were consistently stronger in males and younger patients. Individual clinical information was not available, and the homogeneous population may limit the generalizability of the results. Vitiligo was significantly associated with overt autoimmune thyroid diseases and overt thyroid cancer. Copyright © 2016 American Academy of Dermatology, Inc. Published by Elsevier Inc.

Full Text Available Aim: The aim of this study was to determine the involvement in the salivary glands of the patients with Graves’ Disease, Hashimoto Thyroiditis and controls by detecting the changes of Tc-99m Methoxyisobutylisonitrile (Tc-99m MIBI uptake. Material and Methods: The study was conducted between January 2008 and December 2009. 19 patients with Graves’ disease (6 men, 13 women, 28 Hashimoto Thyroiditis patients (5 men, 23 women and 11 euthyroid controls (4 men, 7 women were evaluated retrospectively. Uptake values of parotid and submandibular glands were calculated by drawing elliptical ROIs (region of interest and using the formula for uptake calculation. Result: In all three groups, in parotis glands, a statistical significant difference between Tc-99m MIBI uptake was not detected. The Tc-99m MIBI upateke values in submandibular glands were statistically different among patients with Graves’Disease, Hashimoto Thyroiditis, as well as in Control group (p<0.05. Conclusion: We concluded that the different uptake values of Tc-99m-MIBI in submandibular glands in Graves disease and Hashimoto thyroiditis as compared to the control group patient would be results of the histopathological features, such as autoimmunity, high mitochondria number and inflammatory reaction.

Introduction: To evaluate the computed tomographic (CT) findings of primary thyroid lymphoma. Methods and material: The clinicopathological data and CT images of nine patients with primary thyroid lymphoma were retrospectively reviewed. The CT appearances were classified into three types: type 1, a solitary nodule surrounded by normal thyroid tissue; type 2, multiple nodules in the thyroid, and type 3, a homogeneously enlarged both thyroid glands with a reduced attenuation with or without peripheral thin hyperattenuating thyroid tissue. Results: All patients had a rapidly enlarging thyroid mass and coexistent Hashimoto's thyroiditis. One patient showed type 1 pattern, three type 2, and five type 3. Six patients had homogeneous tumor isoattenuating to surrounding muscles. The tumors had a strong tendency to compress normal remnant thyroid and the surrounding structure without invasion. Conclusion: Primary thyroid lymphoma should be included in the differential diagnosis when old female had a homogeneous thyroidal mass isoattenuating to muscles, which does not invade surrounding structures.

To evaluate the values of the thyroid autoantibody measured by radioimmunoassay (RIA) and compare it with hemagglutination method (HA) in the normal and the thyroid disease, data were obtained from total 618 persons; 236 healthy persons, 217 patients with Graves disease (including 113 patients with undertreated Graves' disease), 100 Hashimoto's disease, 31 thyroid nodule, and 34 simple goiter. RSR kit made in England was used and could be detected at least 3 U/ml. The positive rates of normal group were antirnicrosomal antibody (AMA) 31.8%, antithyroglobulin antibody (ATA) 44.5% by RIA and there was no considerable change in sex and age distribution. In Graves disease, the positive rates of AMA and ATA were 90.4, 76.9% by RIA, 85, 39% by HA. In Hashimoto's disease, 94,91% by RIA, and 87,48% by HA, respectively. The autoantibody titer by RIA in thyroid autoimmune disease as welt as in normal group was more sensitive than that by HA, especially in ATA. There were linear relationships between the titer of RIA and that of HA in AMA of Graves disease and AMA and ATA of Hashimotos disease. There was no relationship among thyroid autoantibody, free T, index, TBII, and TSH. The titers of AMA and ATA were found to decrease in patients with Graves disease during the course of antithyroid drug therapy. Of the 236 normal subjects, thirty-seven (15.7%) had concentrations of above 7.5 U/ml in AMA, forty-four (18. 6%) above 9 U/ml in ATA. These values were considered as the upper limit for the normal range. In Graves disease, 82,7, 53.8% were above 7.5, 9 U/ml, respectively; In Hashimoto's disease, HZ, 79% were positive. We conclude that RIA was more sensitive than HA in measuring the thyroid autoantibody, but we will study further more for determining the normal range and its interpretation.

Recent data suggest that increased somatostatin receptor (SSTR) expression is detectable in several thyroid diseases. This raises the question as to the specificity and pathophysiologic relevance of these findings. Therefore, we systematically evaluated Indium-111 (In-111) pentetreotide scintigraphies and Gallium-68 (Ga-68) DOTA-Phe(1)-Tyr(3)-Octreotide (DOTATOC) positron emission tomography (PET) scans for thyroid radiotracer uptake. Relative binding of In-111 pentetreotide in the thyroid was measured by region of interest (ROI) technique in 4-hour and 24-hour post-injection (p.i.) planar images of 73 patients undergoing In-111 pentetreotide scintigraphy. Ga-68 DOTATOC PET scans of 77 patients were analyzed by ROI technique applied to coronal slices of 1 cm (0.39 inch) thickness with highest uptake in the thyroid region. A basal indium In-111 and Ga-68 DOTATOC uptake was found in normal thyroid glands. Hot nodules, disseminated thyroid autonomy, and most cases of active Hashimoto's disease as well as goiters and nodular thyroids showed increased In-111 pentetreotide and/or Ga-68 DOTATOC uptake. Higher relative In-111 pentetreotide uptake in the 24-hour p.i. images as compared to the 4-hour p.i. images except for patients after thyroidectomy indicates specific receptor binding in the thyroid. The increased In-111 pentetreotide and Ga-68 DOTATOC uptake in active Hashimoto's disease is most likely related to the lymphocytic infiltration of the thyroid. However, the physiologic or pathophysiologic relevance of the increased In-111 pentetreotide and Ga-68 DOTATOC uptake in normal thyroid glands, hot and cold nodules, and goiters and nodular thyroids remain to be determined.

Objective: The only method of laboratory diagnosis for autoimmune thyroid diseases used to be serum TGA and TMA detections. Morerecently, quantitative analysis of TPOAb has been introduced. To assess the relative sensitivity of these tests , positive rates detected with the respective tests were compared. Methods: Serum TGA, TMA (with RIA) and TPOAb (with chemiluminescence enzyme immunoassay) were simultaneously detected in 998 cases of thyroid diseases (hyperthyroidism 307, Hashimoto's disease 193, simple goiter 498). For complementary sake, fine needle aspiration cytology was obtained in a number of cases including all the patients with Hashimoto's disease. Results: Positive detection rate of TPOAb in three groups of patients (hyperthyroidism, Hashimoto's, simple goiter) was 81.76%, 96.89 % and 42.97% respectively. With TMA, the positive rate was only 54.72%, 65.80%, 22.09% respectively. About one third more cases would be detected with the newer method. Conclusion: For the laboratory detection of auto immune thyroid diseases, quantitative analysis of TPOAb is much wore sensitive than the conventional TMA detection. (authors)

A pattern of cerebral perfusion anomalies between Major Depressive Disorder and Hashimoto Thyroiditis

Science.gov (United States)

2011-01-01

Background This study aims to evaluate relationship between three different clinical conditions: Major Depressive Disorders (MDD), Hashimoto Thyroiditis (HT) and reduction in regional Cerebral Blood Flow (rCBF) in order to explore the possibility that patients with HT and MDD have specific pattern(s) of cerebral perfusion. Methods Design: Analysis of data derived from two separate data banks. Sample: 54 subjects, 32 with HT (29 women, mean age 38.8 ± 13.9); 22 without HT (19 women, mean age 36.5 ± 12.25). Assessment: Psychiatric diagnosis was carried out by Simplified Composite International Diagnostic Interview (CIDIS) using DSM-IV categories; cerebral perfusion was measured by 99 mTc-ECD SPECT. Statistical analysis was done through logistic regression. Results MDD appears to be associated with left frontal hypoperfusion, left temporal hypoperfusion, diffuse hypoperfusion and parietal perfusion asymmetry. A statistically significant association between parietal perfusion asymmetry and MDD was found only in the HT group. Conclusion In HT, MDD is characterized by a parietal flow asymmetry. However, the specificity of rCBF in MDD with HT should be confirmed in a control sample with consideration for other health conditions. Moreover, this should be investigated with a longitudinally designed study in order to determine a possible pathogenic cause. Future studies with a much larger sample size should clarify whether a particular perfusion pattern is associated with a specific course or symptom cluster of MDD. PMID:21910915

The Role of Vitamin D in Thyroid Diseases.

2017-09-12

The main role of vitamin D is regulating bone metabolism and calcium and phosphorus homeostasis. Over the past few decades, the importance of vitamin D in non-skeletal actions has been studied, including the role of vitamin D in autoimmune diseases, metabolic syndromes, cardiovascular disease, cancers, and all-cause mortality. Recent evidence has demonstrated an association between low vitamin D status and autoimmune thyroid diseases such as Hashimoto's thyroiditis and Graves' disease, and impaired vitamin D signaling has been reported in thyroid cancers. This review will focus on recent data on the possible role of vitamin D in thyroid diseases, including autoimmune thyroid diseases and thyroid cancers.

This study aims to investigate the impact of psammoma body (PB) on papillary thyroid carcinoma (PTC), and evaluate the association among PB, Hashimoto thyroiditis (HT), and other clinicopathologic characteristics in PTC patients.We conducted a retrospective case-control study involving 1052 PTC patients who underwent total thyroidectomy or lobectomy with lymph node dissection.Psammoma body was observed in 324 out of 1052 PTC (30.8%) patients. Ultrasonographic (US) calcification (P < 0.001), multifocality of the tumor (P = 0.047), lymph node metastasis (LNM) (P < 0.001), HT (P < 0.001), and Primary tumor (T), Regional lymph nodes (N), Distant metastasis (M) staging (P = 0.001) were significantly related to the presence of PB. The presence of PB was significantly associated with US microcalcification (P < 0.001). In the subgroup with HT, compared with the patients without PB, the patients with PB exhibited a higher frequency of central LNM (54.7% vs 32.1%; P < 0.001) and US microcalcification (94.7% vs 38.8%; P < 0.001), as well as smaller tumors (0.9 ± 0.6 vs 1.3 ± 0.9 cm; P < 0.001). In the subgroup without HT, the patients with PB displayed a higher incidence of lateral LNM (25.8% vs 14.6%; P < 0.001), US microcalcification (87.3% vs 52.5%; P < 0.001), and extrathyroidal extension (47.2% vs 34.8%; P = 0.001), as well as larger tumors (1.3 ± 0.9 vs 1.0 ± 0.8 cm; P < 0.001) than without PB. Moreover, in the subgroup with PB, the PTC patients with HT showed a higher LNM (77.9% vs 57.2%; P < 0.001) and a lower frequency of extrathyroidal extension (20.0% vs 47.2%; P < 0.001) than without HT.Psammoma body is a useful predictor of aggressive tumor behavior in PTC patients. HT with PB shows more aggressive behaviors than non-HT with PB in PTC patients.

Abstract The aim of this study was to evaluate the risk of depression in and effect of l-thyroxine therapy on patients with Hashimoto thyroiditis (HT) in Taiwan. In this retrospective, nationwide cohort study, we retrieved data from the Longitudinal Health Insurance Database 2000. We collected data of 1220 patients with HT and 4880 patients without HT for the period 2000 to 2011. The mean follow-up period for the HT cohort was 5.77 years. Univariate and multivariate Cox proportional hazards regression models were used to estimate the risk of depression in the HT cohort. In the HT cohort, 89.6% of the patients were women. Compared with the non-HT cohort, the HT cohort exhibited a higher prevalence of diabetes mellitus, hyperlipidemia, and coronary artery disease. Furthermore, the HT cohort showed a higher overall incidence of depression compared with the non-HT cohort (8.67 and 5.49 per 1000 person-year; crude hazard ratio [HR] = 1.58, 95% confidence interval [CI] = 1.18–2.13). The risk of depression decreased after administration of l-thyroxine treatment for more than 1 year (adjusted HR = 1.02; 95% CI = 0.66–1.59). In Taiwan, the overall incidence of depression was greater in the young HT cohort. l-thyroxine treatment reduced the risk of depression. PMID:26871858

This prospective study was designed to evaluate the potential contributions of high resolution ultrasonography (US) and Tc-99m scintigraphy in the routine diagnosis of thyroid disease. The diagnostic impacts of US and Tc-99m scintigraphy results in 177 patients visiting our thyroid clinic were assessed and scored according to the following criteria: when the information provided by either test supported, confirmed or changed the initial clinical diagnosis, they received scores of 2, 3 and 4 respectively, while score 1 was given when the test itself was useless for the differential diagnosis. US identified focal lesions that both palpation and scintigraphy had failed to detect in 14 (12.1%) of 116 patients with diffuse thyroid diseases, suggesting the necessity of Hashimoto's thyroiditis, adenoma, adenocarcinoma and adenomatous goiter, and vice versa in the diagnosis of hyperthyroid and euthyroid Graves's diseases. Thus, the advantages of US over scintigraphy for morphological evaluation were confirmed. US was particularly useful for the differential diagnosis of adenomatous goiter from Hashimoto's thyroiditis or a single nodular disease. In contrast, scintigraphy gave functional images, being especially helpful for the differential diagnosis of thyrotoxicosis. (author).

Thyroid imaging is indicated to evaluate congenital hypothyroidism during newborn screening or in cases of a palpable thyroid mass in children and adolescents. This pictorial essay reviews the ultrasonography (US) of thyroid diseases in children and adolescents, including normal thyroid gland development, imaging features of congenital thyroid disorders (dysgenesis, [aplasia, ectopy, hypoplasia], dyshormonogenesis, transient hypothyroidism, thyroglossal duct cyst), diffuse thyroid disease (Grave's disease, Hashimoto's thyroiditis, and suppurative thyroiditis), and thyroid nodules. The primary imaging modalities for evaluating thyroid diseases are US and radionuclide scintigraphy. Additionally, US can be used to guide aspiration of detected nodules.

Hashimoto's thyroiditis (HT) is a chronic autoimmune thyroid disease caused by an interaction between genetic factors and environmental conditions, both of which are yet to be fully understood. The management of HT depends on its clinical manifestations, commonly including diffuse or nodular goiter with euthyroidism, subclinical hypothyroidism and permanent hypothyroidism. However, in most cases of patients with HT, lifelong levothyroxine substitution is required. The additional role of diet for the management of HT is usually overlooked. A literature search regarding the importance and the influence of iodine, selenium, vitamin D and gluten on HT was conducted. In HT careful supplementation of possible deficiencies is recommended for the dietary management of these patients. The use of a diet low in gluten among HT patients with or without celiac disease (CD) is discussed.

To study the diagnostic value of Th1/Th2 cell cytokine and thyroid autoantibody in autoimmune thyroid diseases (AITD), 28 patients with Graves' disease (GD), 15 patients with hyperthyroidism and thyroiditis (GDIII), 13 patients with Hashimoto's hyperthyroidism (HTL), 21 patients with Hashimoto's thyroiditis(HT)and 20 healthy subjects were enrolled in this study. The serum concentrations of Th1 cytokine (IFN-γ) and Th2 cytokine (IL-4) were determined by ELISA. The serum levels of thyrotropin receptor antibodies (TRAb), thyroglobulin antibodies (TGAb) and thyroid peroxidase antibodies (TPOAb) were measured by RIA. The relationship between the serum levels of IFN-γ, IL-4 and TRAb, TGAb and TPOAb were analyzed. The results showed that IFN-γ levels from higher to lower in different groups were in the order of HT, HTL, GDIII, GD and the IL-4 were GD, GDIII, HTL, HT, respectively. There was significant difference in the IFN-γ (P<0.05) and IL-4 levels (P<0.01) between GDIII and HTL groups. There was no significant difference in TGAb and TPOAb between GDIII and HTL groups. In HT group, IFN-γ levels was positively correlated with TGAb and TPOAb (r=0.67,0.54,P<0.01). In GD group, IL-4 was positively correlated with TRAb (r =0.71,P<0.01). The imbalance of Th1/Th2 cell cytokine reflects pathologic change and abnormality of immune function in AITD patients. The detection of Th1/Th2 cell cytokine combined with thyroid autoantibody may be regarded as an indicator in the diagnosis of autoimmune thyroid diseases. (authors)

Auto immune thyroid disease (AITD) is the common organ specific autoimmune disorder, Hashimoto thyroiditis (HT) and Grave's disease (GD) are its well-known sequelae. It occurs due to loss of tolerance to autoantigens thyroid peroxidase (TPO), thyroglobulin (Tg), thyroid stimulating hormone receptor (TSH-R) which leads to the infiltration of the gland. T cells in chronic autoimmune thyroiditis (cAIT) induce apoptosis in thyroid follicular cells and cause destruction of the gland. Presences of TPO antibodies are common in HT and GD, while Tg has been reported as an independent predictor of thyroid malignancy. Cytokines are small proteins play an important role in autoimmunity, by stimulating B and T cells. Various cytokines IL-1α, IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12, IL-13, IL-14, TNF-α and IFN-γ are found in thyroid follicular cells which enhance inflammatory response with nitric oxide (NO) and prostaglandins.

The purpose of this study was to analyse the various patterns of calcification demonstrated in the anterior and lateral neck roentgenograms of 213 unselected patients with thyroid enlargement. The patterns of thyroid calcifications were correlated with clinical, surgical and histological findings. The results were as follows: 1. Of 213 cases of thyroid enlargement, 180 cases were benign and 168 cases were female. 2. The calcification rate was high in the chronic thyroid enlargement. 3. The incidence of calcification was 30.2% in the malignancy and 17.2% in the benign disease. There was no calcification in the Hashimoto's disease. 4. The nodular calcification was demonstrated in the both benign and malignant disease but curvilinear calcification was predominantly seen in benign disease.

The human leukocyte antigen (HLA) genomic region spanning about 4 Mb is the most gene dense and the polymorphic stretches in the human genome. A total of the 269 loci were identified, including 145 protein coding genes mostly important for immunity and 50 noncoding RNAs (ncRNAs). Biological function of these ncRNAs remains unknown, becoming hot spot in the studies of HLA-associated diseases. The genomic diversity analysis in the HLA region facilitated by next-generation sequencing will pave the way to molecular understanding of linkage disequilibrium structure, population diversity, histocompatibility in transplantation, and associations with autoimmune diseases. The 4-digit DNA genotyping of HLA for six HLA loci, HLA-A through DP, in the patients with Graves' disease (GD) and Hashimoto thyroiditis (HT) identified six susceptible and three resistant HLA alleles. Their epistatic interactions in controlling the development of these diseases are shown. Four susceptible and one resistant HLA alleles are shared by GD and HT. Two HLA alleles associated with GD or HT control the titers of autoantibodies to thyroid antigens. All these observations led us to propose a new model for the development of GD and HT. Hematopoietic stem cell transplantation from unrelated donor (UR-HSCT) provides a natural experiment to elucidate the role of allogenic HLA molecules in immune response. Large cohort studies using HLA allele and clinical outcome data have elucidated that (1) HLA locus, allele, and haplotype mismatches between donor and patient, (2) specific amino acid substitution at specific positions of HLA molecules, and (3) ethnic background are all responsible for the immunological events related to UR-HSCT including acute graft-versus-host disease (GVHD), chronic GVHD, graft-versus-leukemia (GvL) effect, and graft failure. © 2016 Elsevier Inc.

Lymphocytic thyroiditis associated with progressive thyroid atrophy is described in CRHL beagles. Depressed thyroid function was present in many of these dogs, as evidenced by clinical signs of hypothyroidism, elevation of serum cholesterol levels, depressed serum triiodothyronine levels, and alteration of basophils of the antero-medial region and/or unilateral or bilateral obliteration of the thyroid glands by neoplasia. Microscopic changes in the thyroid glands included lymphocytic thyroiditis, thyroid follicular atrophy, adenomatous hyperplasia of follicula cells and C-cells, and follicular cells neoplasia. This disease occurred with no sex predisposition in dogs 2 through 11 years of age. The disease does not appear to be influenced by previous radiation exposure but may be familial. In contrast to thyroid disease in some other beagle colonies, the disease in CRHL beagles more closely resembles atrophic thyroiditis of man rather than human Hashimoto's thyroiditis

The thyroid is the purest endocrine gland in the body and is likely to produce clinically significant abnormalities after external radiotherapy. Functional clinical modifications after direct irradiation exceeding 30 Gy are essentially related to hypothyroidism which may be clinically overt or subclinical with normal serum free thyroxine levels and high thyrotropin concentrations; the risk of hyperthyroidism, silent thyroiditis and Hashimoto`s disease is also increased. secondary hypothyroidism related to irradiation of the hypothalamus and the pituitary gland may arise with doses over 40-50 Gy following treatment for brain and nasopharyngeal tumors - Morphological glandular modifications induced by radiotherapy are responsible for the appearance of benign adenomas, more rarely cystic degenerations and specially well differentiated papillary or follicular carcinomas among children and adults. After irradiation during childhood for benign or malignant tumors, thyroid cancers are more frequent, higher for younger children, and the relative excess risk is increased from 15.6-to 53-fold; tumors can belatedly occur, more than 35 years after initial therapy. Thereby, in order to limit excess morbidity, it is evident that long term supervision with careful clinical and biological evaluations is necessary for patients who previously received neck, upper mediastinum and pituitary radiation therapy.

Hashimoto's thyroiditis (HT) is a T cell-mediated autoimmune disease. However, little is known about the role of different subsets of natural killer (NK) and natural killer T (NKT) cells at the early stage of the HT process. A total of 45 euthyroid patients with new onset HT and 40 age/gender-matched healthy controls (HC) were examined for the frequency of different subsets of NK and NKT cells and their function by flow cytometry. In comparison with that in HC, significantly higher percentages of peripheral blood CD3-CD56+ NK, NKG2D+, NKp30+ NK and NKT cells, but significantly lower percentages of NKG2A+, KIR2DL3+ inhibitory NK and NKT cells were detected in the HT patients. Furthermore, the percentages of NKG2D+ NK cells were correlated positively with the concentrations of serum anti-thyroid peroxidase antibody (TPOAb) in the HT patients. Moreover, the percentages of inducible IFN-γ and CD107a+ NK cells in the HT patients were significantly higher than those in HC. Our data suggest that activated NK cells may participate in the early pathogenic process of HT.

Objective: To establish a fluorescent-enzyme immunoassay (FEIA) with recombinant human thyroid peroxidase (hTPO) as the antigen. Methods: Sera of 326 healthy people, 119 cases of Hashimoto's thyroiditis (HT), 116 cases of Graves disease (untreated), 28 cases of nodular goiter, 10 ca-ses of subacute thyroiditis and 6 cases of simple goiter were measured by the FEIA with recombinant hTPO as the antigen. Rrank sum test and χ 2 -test were used in inter-groups. Results: (1) Concentration above 4000 U/L was considered to be positive. (2) The intra-assay coefficient of variation (CV) and the inter-as-say CV were 4.59% ∼ 6.52% and 17.37% ∼ 17.45%. (3) The values measured by the FEIA were positively correlated with the values measured by hTPO antibody (hTPOAb) commercial kit (r=0.80, P 2 = 53.45, 39.30, 15.41 and 21.74, all P < 0.01). Conclusions: The method can be applied in the serum measurement of thyroid disease. HT presented the highest positive rate, therefore, the FEIA was an effective method in diagnosing HT. (authors)

In recent years, the authors of epidemiological studies have documented that autoimmune diseases are a major problem of modern society and are classified as diseases of civilization. Autoimmune thyroid diseases (ATDs) are caused by an abnormal immune response to autoantigens present in the thyroid gland - they often coexist with other autoimmune diseases. The most common dysfunctions of the thyroid gland are hypothyroidism, Graves-Basedow disease and Hashimoto's disease. Hashimoto's thyroiditis can be the main cause of primary hypothyroidism of the thyroid gland. Anthropometric, biochemical and physicochemical parameters are used to assess the nutritional status during the diagnosis and treatment of thyroid diseases. Patients with hypothyroidism are often obese, whereas patients with hyperthyroidism are often afflicted with rapid weight loss. The consequence of obesity is a change of the thyroid hormones' activity; however, weight reduction leads to their normalization. The activity and metabolic rate of thyroid hormones are modifiable. ATDs are associated with abnormalities of glucose metabolism and thus increased risk of developing diabetes mellitus type 1 and type 2. Celiac disease (CD) also increases the risk of developing other autoimmune diseases. Malnutrition or the presence of numerous nutritional deficiencies in a patient's body can be the cause of thyroid disorders. Coexisting deficiencies of such elements as iodine, iron, selenium and zinc may impair the function of the thyroid gland. Other nutrient deficiencies usually observed in patients suffering from ATD are: protein deficiencies, vitamin deficiencies (A, C, B6, B5, B1) and mineral deficiencies (phosphorus, magnesium, potassium, sodium, chromium). Proper diet helps to reduce the symptoms of the disease, maintains a healthy weight and prevents the occurrence of malnutrition. This article presents an overview of selected documented studies and scientific reports on the relationship of metabolic

Full Text Available Objective. This study aimed to evaluate the CT features of incidentally detected DTD in the patients who underwent thyroidectomy and to assess the diagnostic accuracy of CT diagnosis. Methods. We enrolled 209 consecutive patients who received preoperative neck CT and subsequent thyroid surgery. Neck CT in each case was retrospectively investigated by a single radiologist. We evaluated the diagnostic accuracy of individual CT features and the cut-off CT criteria for detecting DTD by comparing the CT features with histopathological results. Results. Histopathological examination of the 209 cases revealed normal thyroid (n=157, Hashimoto thyroiditis (n=17, non-Hashimoto lymphocytic thyroiditis (n=34, and diffuse hyperplasia (n=1. The CT features suggestive of DTD included low attenuation, inhomogeneous attenuation, increased glandular size, lobulated margin, and inhomogeneous enhancement. ROC curve analysis revealed that CT diagnosis of DTD based on the CT classification of “3 or more” abnormal CT features was superior. When the “3 or more” CT classification was selected, the sensitivity, specificity, positive and negative predictive values, and accuracy of CT diagnosis for DTD were 55.8%, 95.5%, 80.6%, 86.7%, and 85.6%, respectively. Conclusion. Neck CT may be helpful for the detection of incidental DTD.

Fukuchi, M.; Kido, A.; Hyodo, K.; Tachibana, K.; Onoue, K.; Morita, T.; Nagai, K.

1979-01-01

We have investigated the thyroid uptake of Tl-201 in 37 patients with various types of goiter, and in six with normal thyroids. Significant thallium uptake was found in all cases in which there was thyroid enlargement, including Graves' disease, toxic thyroid nodule, primary hypothyroidism, simple goiter, Hashimoto's disease, thyroid carcinoma, and thyroid adenoma. If goiter was absent, however, there was no demonstrable uptake - e.g., in secondary hypothyroidism, subacute thyroiditis, and the normal controls. Thallium uptake did not correlate with thyroid function tests such as BMR, T 3 -RU, T 3 , T 4 , TSH, antithyroid antibodies, or the 24-hr I-131 uptake. In 23 patients with diffuse goiter, on the other hand, maximum Tl-201 uptake correlated well with thyroid weight: r = 0.836 (p < 0.001); y = 0.02 x + 0.06

72 human thyroid were analysed from which 27 corresponded to normal tissue, 30 to nodular goiters(21 'cold' nodules and 9 'hot' nodules), 10 to adenocarcinomas, 3 to ganglionar metastasis of thyroidal adenocarcinoma and 2 to Hashimoto's thyroiditis. The concentration of total albumin and serumalbumin were determined in these tissues thus permitting the estimation of thyralbumin concentration. The results obtained showed a significantly higher concentration of thyralbumin as compared to serumalbumin in all tissue samples. A significant correlation between the content of blood in the thyroid extracts and its concentration of thyralbumin was also found. The hypothesis that thyralbumin was produced in the gland was therefore accepted. Furthermore, the thyralbumin content of abnormal tissues was always higher than that found in normal thyroids [pt

2015-08-01

Full Text Available Obiectives: To assess the prevalence of thyroid dysfunction in a group of pregnant women, originating from Dobrogea region of southeastern Romania, considered to be an area without iodine deficiency, including the Black Sea area. Materials and methods: We enrolled 324 pregnant women in different trimesters of pregnancy. Each case was reviewed by a detailed madical history, clinical examination and by serum dosage of thyroid hormones: TSH, FT4, and the antithyroidperoxidase. They were evaluated by comparison with trimester -specific reference range for TSH recommended by American Thyroid Association, then the results were compared with those obtained using the manufacturers reference range. Abortion rate was also analysed. Results: The prevalence of thyroid dysfunction was different in all the 3 trimesters: subclinical hypothyroidism being the most frequently approx. 24% of all cases; 7% of pregnant women had overt hypothyroidism. Incidence of thyrotoxicosis in entire study cases was approx. 5.5%. The most frecvent thyroid autoimune disorders were Hashimoto thyroiditis: 42 % - I trimester, 26,6% in II trimester and about 12,5 % in III-trimester; Graves disease have an incidence of only 0,9 % (n=3.The difference between reference methods eluded a lower number of cases using manufactures reference range for TSH (P< 0,001, but higher for recommended trimester - specific TSH value, confirming the undervalueted hypothesis. The risk of misclassifying the hypothyroidism is between 3 %-8 %. Conclusion: Necessity for thyroid hormone dosage periodic/trimesterly/ in pregnancy is a preventive measure. The reference values for hormonal dosage requires trimester-specific assessment. The possibility of hormonal disorders during pregnancy is common. The need for specific therapy at diagnosis depends on the nature of hormonal disorder. Further precautions are needed in pregnant women with known autoimmune thyroid disorder or newly diagnosed

Thyroid hormones exert critical roles throughout the body and play an important and permissive role in neuroendocrine, neurological, and neuromuscular function. We performed a PubMed search through June 2014 with search terms including "hypothyroidism," "hyperthyroidism," "neurological complications," "neuropathy," "myopathy," "congenital hypothyroidism," and "encephalopathy." Relevant publications reviewed included case series, individual case reports, systematic reviews, retrospective analyses, and randomized controlled trials. The neurological outcomes of congenital hypothyroidism were reviewed, along with the clinical features of associated neuromuscular syndromes of both hypothyroidism and hyperthyroidism, including other autoimmune conditions. Evidence for, and pathophysiological controversies surrounding, Hashimoto encephalopathy was also reviewed. The establishment of widespread newborn screening programs has been highly successful in attenuating or preventing early and irreversible neurological harm resulting from congenital thyroid hormone deficiency, but some children continue to display neuromuscular, sensory, and cognitive defects in later life. Acquired disorders of thyroid function such as Hashimoto thyroiditis and Graves' disease are associated with a spectrum of central nervous system and/or neuromuscular dysfunction. However, considerable variation in clinical phenotype is described, and much of our knowledge of the role of thyroid disease in childhood neurological disorders is derived from adult case series. Early and aggressive normalization of thyroxine levels in newborn infants with congenital hypothyroidism is important in minimizing neurological sequelae, but maternal thyroid hormone sources are also critically important to the early developing brain. A spectrum of neurological disorders has been reported in older children with acquired thyroid disease, but the frequency with which these occur remains poorly defined in the literature, and

Creutzfeldt-Jakob disease and Hashimoto's encephalopathy often show similar clinical presentation. Among Creutzfeldt-Jakob disease mimics, Hashimoto's encephalopathy is particularly important as it is treatable with corticosteroids. Thus, in cases of middle-aged woman diagnosed with probable Creutzfeldt-Jakob disease and who exhibit high titers of antithyroid antibodies, corticosteroid pulse therapy is typically performed with expectations of near complete recovery from Hashimoto's encephalopathy. Herein, we provide the first case report that exhibited a negative effect of corticosteroid pulse therapy for a patient with Creutzfeldt-Jakob disease with features of Hashimoto's encephalopathy. We report a case of 59-year-old Asian woman with blurred vision, dysarthria, myoclonus, and rapidly progressive dementia. Cerebrospinal fluid showed 14-3-3 protein positive. Electroencephalogram showed periodic sharp waves (1.5 Hz) at the bilateral frontal or occipital areas. Magnetic resonance imaging showed high signal intensities at the bilateral cerebral cortex, caudate nucleus, and putamen. The patient was diagnosed with probable Creutzfeldt-Jakob disease. However, serum analysis showed a high titer of antithyroid antibodies. We started corticosteroid pulse therapy with subsequent aggravation of seizure activity including generalized myoclonus, epilepsia parialis continua, and ballistic dyskinesia, which was effectively treated with clonazepam. We provide evidence of a case of Creutzfeldt-Jakob disease that exhibited clinical deterioration after corticosteroid therapy. Although histopathological confirmation with brain biopsy is not easily available in Creutzfeldt-Jakob disease patients, selective initiation of corticosteroid pulse therapy should be considered in cases of uncertain diagnosis for differentiation with Hashimoto's encephalopathy.

Full Text Available Background: The prevalence of both islet cell and adrenal autoimmunity among Asian Indian hypothyroidism patients with Hashimoto's thyroiditis (HT is lacking in literature. Objectives: The objective of this study was to assess the proportion of Addison's disease (AD and type 1 diabetes mellitus (T1DM in patients with HT. Materials and Methods: The patients with hypothyroidism due to HT were included in this study over 2 years. Primary hypothyroidism was defined as high serum thyroid-stimulating hormone (>5.5 mIU/L with or without low thyroxine level. HT was defined by the presence of high thyroid peroxidase antibody (Ab titer (>35 IU/ml. Autoimmune markers of AD and T1DM, i.e., adrenal (21-hydroxylase Ab, glutamic acid decarboxylase (GAD Ab, and insulinoma-associated antigen-2 (IA-2 Ab were measured among them. In addition, 250 μg adrenocorticotropic hormone (ACTH stimulation test was done in patients with adrenal Ab. Similarly, beta cell function was assessed in patients with GAD and/or IA-2 Ab. Results: Out of 150 patients screened, 136 patients were included in this study. Seven patients had adrenal Ab while 15 had IA-2 Ab. The GAD Ab was not present in any of the patients in the study. ACTH stimulation test was done in four of seven patients with adrenal Ab and beta cell function was assessed in 8 of 15 patients with islet cell Ab. All patients with adrenal Ab had normal adrenal function and 1 out of 15 with IA-2 Ab developed diabetes mellitus during follow-up. Conclusions: Either adrenal or islet cell Ab was found in 16% Asian Indian hypothyroidism patients with HT.

Full Text Available Abstract Viral infections are frequently cited as a major environmental factor involved in subacute thyroiditis and autoimmune thyroid diseases This review examines the data related to the role of viruses in the development of thyroiditis. Our research has been focused on human data. We have reviewed virological data for each type of thyroiditis at different levels of evidence; epidemiological data, serological data or research on circulating viruses, direct evidence of thyroid tissue infection. Interpretation of epidemiological and serological data must be cautious as they don't prove that this pathogen is responsible for the disease. However, direct evidence of the presence of viruses or their components in the organ are available for retroviruses (HFV and mumps in subacute thyroiditis, for retroviruses (HTLV-1, HFV, HIV and SV40 in Graves's disease and for HTLV-1, enterovirus, rubella, mumps virus, HSV, EBV and parvovirus in Hashimoto's thyroiditis. However, it remains to determine whether they are responsible for thyroid diseases or whether they are just innocent bystanders. Further studies are needed to clarify the relationship between viruses and thyroid diseases, in order to develop new strategies for prevention and/or treatment.

Introduction: Chronic lymphocytic thyroiditis [Hashimoto thyroiditis (HT)] is a common thyroid lesion diagnosed on fine-needle aspiration cytology (FNAC). Apart from FNAC, various other parameters, such as clinical features, ultrasonographic findings, antithyroid antibody levels, hormone profiles, and radionuclide thyroid scan, are also taken into consideration in making a diagnosis of HT. Aims: To grade lymphocytic thyroiditis based on the cytomorphology and to correlate the cytological grades with the levels of antithyroid peroxidase antibody (ATPO), antithyroglobulin antibody (ATG), and thyroid stimulating hormone (TSH). Materials and Methods: During a period of one and half years, 1,667 cases underwent FNAC of thyroid at our tertiary care center. Of these, 128 cases had cytological evidence of lymphocytic thyroiditis. Out of these, in 60 cases the levels of ATPO, ATG, and TSH were known. The cytological grades of lymphocytic thyroiditis in these cases were correlated with these parameters. Results: Out of the 60 cases, 55 were females. Age ranged from 5 years to 70 years, with majority of patients in third decade. Diffuse enlargement of thyroid was the commonest presentation. However, 14 cases presented with nodular disease. Majority of the patients had grade 1 thyroiditis (27 cases), followed by grade 2 thyroiditis (22 cases). Cytomorphology was diagnostic of thyroiditis in all 60 cases. ATPO was elevated in 57 cases and ATG was elevated in 40 cases. Elevated level of TSH was seen in only 18 cases. In 39 cases, TSH value was normal. There was no correlation between the cytological grades of thyroiditis and the levels of antithyroid antibodies and TSH. Conclusion: Lymphocytic infiltration of thyroid follicles is pathognomonic of lymphocytic thyroiditis. Positivity for antithyroid antibodies is strongly associated with HT but no correlation was observed between the grades of thyroiditis and the levels of ATPO, ATG, and TSH. PMID:27756987

Full Text Available Objective. Black thyroid is a rare pigmented change seen almost exclusively in patients upon minocycline ingestion, and the process has previously been thought to be generally benign. There have been 61 reported cases of black thyroid. We are aware of 13 cases previously reported in association with thyroid carcinoma. This paper reports six patients with black thyroid pigmentation in association with thyroid carcinoma. Design. The medical records of six patients who were diagnosed with black thyroid syndrome, all of whom underwent thyroid surgery, were reviewed. Data on age, gender, race, preoperative fine needle aspiration biopsy (FNA, thyroid function levels, and pathology reports were collected. Main Outcome. The mean age was 60 years. There were 5 females, 4 of whom were African American. All patients were clinically and biochemically euthyroid. Black pigmentation was not diagnosed in preoperative FNA, and only one patient had a preoperative diagnosis of papillary thyroid carcinoma. The other patients underwent surgery and were found to have black pigmentation of the thyroid associated with carcinoma. Conclusions. FNA does not diagnose black thyroid, which is associated with thyroid carcinoma. Thyroid glands with black pigmentation deserve thorough pathologic examination, including several sections of each specimen.

Kinetics of the thyroid pertechnetate trap were assessed in 39 normal subjects, five untreated patients with Graves' disease (two before and after treatment), two hypothyroid patients, and in one patient each with Hashimoto's thyroiditis of recent onset, subacute thyroiditis, and massive anaplastic carcinoma. In normal subjects, the effects of sex, time of day, and order of experimental sessions were studied. A three-compartment model was assumed for all studies. Data on thyroidal and neck-background pertechnetate were collected with a multicrystal camera during 40 min after iv injection. The two thyroidal compartments in the model - the follicular cell, v/sub 2/, and the colloidal plasma-equivalent space, V/sub 3/ - is a multi-exponential function of plasma radioactivity, V/sub 1/. None of the model parameters was systematically affected by sex and order of session did not consistently alter any parameter, except for V/sub 3/, which was greater in session 2 than in session 1. That increase was not consistent and is believed to be spurious. Time of day affected only the exit rate constant from the colloid ..lambda../sub 23/, which was increased later in the day (P < 0.02). Distribution of the normal parameters was more log-normal than normal. After 5% were excluded at the high end and at the low end, the range for a parameter, p, was found empirically to be: antiln (mean ln p - 1.7 s.d. ln p), and antiln (mean ln p + 1.5 s.d. ln p). In Graves' disease, V/sub 2/ is increased (P < 0.02), but the increases in V/sub 3/ and in ..lambda../sub 21/ (the clearance into the thyroid from serum) are more dramatic (P < 10/sup -8/). After treatment, V/sub 3/ and ..lambda../sub 21/ fell toward normal. The hypothyroid patients showed no trap activity, and the trap was normal in the patient with early Hashimoto's thyroiditis. The patients with subacute thyroiditis and anaplastic carcinoma had increases in V/sub 2/, V/sub 3/, and ..lambda../sub 21/, but the

Thyroiditis is a general term that encompasses several clinical disorders characterized by inflammation of the thyroid gland. The most common is Hashimoto thyroiditis; patients typically present with a nontender goiter, hypothyroidism, and an elevated thyroid peroxidase antibody level. Treatment with levothyroxine ameliorates the hypothyroidism and may reduce goiter size. Postpartum thyroiditis is transient or persistent thyroid dysfunction that occurs within one year of childbirth, miscarriage, or medical abortion. Release of preformed thyroid hormone into the bloodstream may result in hyperthyroidism. This may be followed by transient or permanent hypothyroidism as a result of depletion of thyroid hormone stores and destruction of thyroid hormone-producing cells. Patients should be monitored for changes in thyroid function. Beta blockers can treat symptoms in the initial hyperthyroid phase; in the subsequent hypothyroid phase, levothyroxine should be considered in women with a serum thyroid-stimulating hormone level greater than 10 mIU per L, or in women with a thyroid-stimulating hormone level of 4 to 10 mIU per L who are symptomatic or desire fertility. Subacute thyroiditis is a transient thyrotoxic state characterized by anterior neck pain, suppressed thyroid-stimulating hormone, and low radioactive iodine uptake on thyroid scanning. Many cases of subacute thyroiditis follow an upper respiratory viral illness, which is thought to trigger an inflammatory destruction of thyroid follicles. In most cases, the thyroid gland spontaneously resumes normal thyroid hormone production after several months. Treatment with high-dose acetylsalicylic acid or nonsteroidal anti-inflammatory drugs is directed toward relief of thyroid pain.

We have investigated the thyroid uptake of Tl-201 in 37 patients with various types of goiter, and in six with normal thyroids. Significant thallium uptake was found in all cases in which there was thyroid enlargement, including Graves' disease, toxic thyroid nodule, primary hypothyroidism, simple goiter, Hashimoto's disease, thyroid carcinoma, and thyroid adenoma. If goiter was absent, however, there was no demonstrable uptake - e.g., in secondary hypothyroidism, subacute thyroiditis, and the normal controls. Thallium uptake did not correlate with thyroid function tests such as BMR, T/sub 3/-RU, T/sub 3/, T/sub 4/, TSH, antithyroid antibodies, or the 24-hr I-131 uptake. In 23 patients with diffuse goiter, on the other hand, maximum Tl-201 uptake correlated well with thyroid weight: r = 0.836 (p < 0.001); y = 0.02 x + 0.06.
