    Background.  Common variants in the interleukin 12B (IL12B) gene are associated with predominantly inflammatory (Th1) or antibody-mediated (Th2) immune responses. Since Hashimoto's disease and Graves' disease are thought to arise from mainly Th1 and Th2 immune responses respectively, we...... hypothesized that IL12B genotype may influence the clinical presentation of autoimmune thyroid disease. Objective.  We tested for differences in IL12B genotype between Graves' disease and Hashimoto's disease. Patients.  We studied a discovery cohort of 203 Australian women and 37 men with autoimmune thyroid...... cohort, rs41292470 and rs3212227 genotypes did not differ significantly between Hashimoto's disease and Graves' disease. In Australian males (but not females), rs6887695 genotype differed between Hashimoto's disease and Graves' disease, with a minor allele frequency (MAF) of 14% and 41% respectively (P=0...

    The two major autoimmune thyroid diseases (ATDs) include Graves' disease (GD) and autoimmune thyroiditis (AT); both of which are characterized by infiltration of the thyroid by T and B cells reactive to thyroid antigens, by the production of thyroid autoantibodies and by abnormal thyroid function (hyperthyroidism in GD and hypothyroidism in AT). While the exact etiology of thyroid autoimmunity is not known, it is believed to develop when a combination of genetic susceptibility and environment...

    Association between autoimmune thyroiditis (CLT) and thyroid cancer remains not clear. Although both diseases often occur simultaneously in histological samples, it is not yet clear whether CLT can be regarded as a risk factor for thyroid malignancy. This review focus on the known epidemiological and molecular genetics links between both diseases. Most studies have shown a significant association between thyroid cancer and positive antibodies to thyroglobulin and histological evidence of CLT, as well. Both disorders share some risk factors (greater incidence in women, in areas with adequate supply of iodine and in patients after radiotherapy of the neck) and molecular genetics linkage. For example: RET/PTC rearrangements could be more often found in carcinomas associated with CLT, but this mutation could be found in benign lesions such as CLT, as well. CLT seems to be a positive prognostic factor in patients with differentiated thyroid cancer. It is associated with less invasive forms of tumor, lower occurrence of infiltrated lymphatic nodes and a lower risk of recurrence. PMID:26486481

    The association between chronic idiopathic urticaria (CIU) and thyroid autoimmunity has most often been suggested in studies investigating thyroid microsomal antibodies, which are less sensitive and specific than anti-thyroperoxidase antibodies, moreover these studies were not case-control studies in large series. By comparing a large patient series presenting with CIU with a large numbered control group we aimed to learn the extent of autoimmune thyroid disease. We compared the frequency of thyroid autoantibodies in 140 patients with CIU with 181 age-and sex-matched volunteers. Thyroid function tests and thyroid autoantibodies were measured by chemiluminescent immunometric assay in study groups. The frequency of thyroid autoantibodies was significantly higher in patients with CIU than that in healthy controls (29.28 %/5.52%; p CIU and thyroid autoimmunity. PMID:16935798

    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.

    Full Text Available Noonan syndrome is a genetic dominant disease that presents a wide variety of clinical characteristics. Frequently, the syndrome is associated with some autoimmune diseases, especially with chronic autoimmune thyroiditis. We report the case of a 21 years old girl diagnosed with Noonan syndrome and autoimmune thyroiditis relatively late, at the age of 20. The diagnosis was suggested by a cluster of significant clinical elements: facial dysmorphism, short stature, moderate mental retardation. The hormonal profile and karyotype contributed to the final certainty diagnosis. At this moment she is under thyroid substitution treatment.

    Full Text Available Context: Thyroid autoimmunity is a recognized disorder in pregnancy and is associated with a number of adverse pregnancy outcomes. Aim: This study set out to determine the relationship between pregnancy and thyroid autoimmunity in Nigerian women. Settings and Design: This was an analytical cross-sectional study carried out in a tertiary hospital in South Western Nigeria with a total study population of 108 pregnant and 52 nonpregnant women. Subjects and Methods: Serum thyroid stimulating hormone, free thyroxine and thyroid peroxidase antibodies (TPO-Ab were quantitatively determined using enzyme linked immuno-assays. Pregnant women were grouped into three categories ( 28 weeks. The relationship between pregnancy and thyroid autoimmunity was determined using Spearman correlation. Analysis of variance was used in comparison of means, Chi-square test used in analyzing proportions while P ≤ 0.05 was considered as significant. Results: The mean age of the pregnant women was 30.4 ± 6.0 years while the mean gestational age of all pregnant women was 20.6 ± 9.6 weeks. The mean TPO-Ab of 11.58 IU/ml in the pregnant was significantly higher than that of the controls of 7.23 IU/ml (P < 0.001. Out of 108 pregnant women, 27 (25% had elevated TPO-Ab as against about 2% of the nonpregnant women levels P < 0.001. The number of pregnant women with elevated TPO-Ab levels decreased from 33.3% in the first group to 25.6% and 15.2% in the second and third groups. Conclusion: Thyroid autoimmunity expressed by the presence of TPO-Ab is high among pregnant Nigerian women and the frequency of autoimmunity appears to decline with advancing gestational age.

    Full Text Available A 54-year-old female presented with recurrent, widespread, erythematous, painful plaques, over a 3-month period. Skin biopsy was compatible with interstitial granulomatous dermatitis. Additional investigation revealed hypothyroidism and positive anti-thyroid antibodies. Normalization of thyroid function and high-potency topical corticosteroids provided only transitory improvement of the dermatosis. Interstitial granulomatous dermatitis is a histologic inflammatory reaction, with variable cutaneous expression. It has been reported in association with several drugs, lymphoproliferative diseases and autoimmune disorders, such as rheumatoid arthritis, systemic lupus erythematosus and vasculitis, but association with autoimmune thyroiditis is rare. Optimal therapy for this condition is yet to be established, but topical corticosteroids have been a mainstay of treatment. In most cases, this disease is characterized by flares and remissions.Uma doente de 54 anos foi avaliada por placas eritematosas, dolorosas, disseminadas, recorrentes, com 3 meses de evolução. A biopsia cutânea foi compatível com dermatite intersticial granulomatosa. Os restantes exames laboratoriais revelaram hipotiroidismo e anticorpos anti-tiroideus positivos. Apesar da normalização da função tiroideia e de tratamento com corticóide tópico de alta potência, a dermatose melhorou apenas parcialmente. Dermatite intersticial inflamatória é um diagnóstico histopatológico, com expressão clínica variável. Tem sido associada a vários fármacos, doenças linfoproliferativas e autoimunes, nomeadamente artrite reumatóide, lupus eritematoso sistémico e vasculites, mas a associação com tireoidite autoimune é rara. Até ao momento, não foi definido nenhum tratamento específico, mas os corticóides tópicos são dos fármacos mais utilizados. A doença caracteriza-se por períodos de agravamento e remissão.

    2007-10-01

    Celiac disease (CD) or gluten sensitive enteropathy is relatively common in western populations with prevalence around 1%. With the recent availability of sensitive and specific serological testing, many patients who are either asymptomatic or have subtle symptoms can be shown to have CD. Patients with CD have modest increases in risks of malignancy and mortality compared to controls. The mortality among CD patients who comply poorly with a gluten-free diet is greater than in compliant patients. The pattern of presentation of CD has altered over the past three decades. Many cases are now detected in adulthood during investigation of problems as diverse as anemia, osteoporosis, autoimmune disorders, unexplained neurological syndromes, infertility and chronic hypertransaminasemia of uncertain cause. Among autoimmune disorders, increased prevalence of CD has been found in patients with autoimmune thyroid disease, type 1 diabetes mellitus, autoimmune liver diseases and inflammatory bowel disease. Prevalence of CD was noted to be 1% to 19% in patients with type 1 diabetes mellitus, 2% to 5% in autoimmune thyroid disorders and 3% to 7% in primary biliary cirrhosis in prospective studies. Conversely, there is also an increased prevalence of immune based disorders among patients with CD. The pathogenesis of co-existent autoimmune thyroid disease and CD is not known, but these conditions share similar HLA haplotypes and are associated with the gene encoding cytotoxic T-lymphocyte-associated antigen-4. Screening high risk patients for CD, such as those with autoimmune diseases, is a reasonable strategy given the increased prevalence. Treatment of CD with a gluten-free diet should reduce the recognized complications of this disease and provide benefits in both general health and perhaps life expectancy. It also improves glycemic control in patients with type 1 diabetes mellitus and enhances the absorption of medications for associated hypothyroidism and osteoporosis. It

    Full Text Available Autoimmune thyroid diseases (ATDs are immune-endocrine disorders affecting the thyroid gland and, eventually, also a number of other systemic targets, including the brain and the nervous system. Encephalopathy associated with autoimmune thyroid disease (EAATD is a rare, heterogeneous condition arising from the background of an ATD. It is characterised by neurological and/or psychiatric symptoms with acute or sub-acute onset, and virtually any neurological or psychiatric symptom can appear. However, EAATD often presents with confusion, altered consciousness, seizures, or myoclonus. The majority of cases are associated with Hashimoto’s thyroiditis, but a number of patients with Graves’ disease have also been described. EAATD is likely an immune-mediated disorder. Its exact prevalence has not been precisely elucidated, with an increasing number of cases reported in the last few years. Most EAATD patients respond in a dramatic manner to corticosteroids. However, the immunosuppressive treatment may require a long course (up to 12 months. The increasing number of EAATD cases reported in the literature demonstrates a growing interest of the scientific community about this condition, which still requires a better definition of its pathophysiology, the diagnostic criteria, and the most appropriate management, including the long-term follow-up of patients. The current clinical evidence about EAATD is mostly based on the report of single cases or small cohort studies. In this review, we present the current knowledge about EAATD, with a dedicated focus to the clinical management of the patients from a diagnostic and therapeutic perspective.

    The prevalence of celiac disease autoimmunity or tissue transglutaminase autoantibodies (TGA) amongst patients with type 1 diabetes (T1D) and autoimmune thyroid disease (AITD) in the Chinese population remains unknown. This study examined the rate of celiac disease autoimmunity amongst patients with T1D and AITD in the Chinese population. The study included 178 patients with type 1 diabetes and 119 with AITD where 36 had both T1D and AITD, classified as autoimmune polyglandular syndrome type 3 variant (APS3v). The study also included 145 patients with type 2 diabetes (T2D), 97 patients with non-autoimmune thyroid disease (NAITD), and 102 healthy controls. Serum islet autoantibodies, thyroid autoantibodies and TGA were measured by radioimmunoassay. TGA positivity was found in 22% of patients with either type 1 diabetes or AITD, much higher than that in patients with T2D (3.4%; pdiseases were present. Routine TGA screening in patients with T1D or AITD will be important to early identify celiac disease autoimmunity for better clinical care of patients. PMID:27427767

    Several studies found a higher prevalence of Autoimmune Thyroid Disease (ATD) in patients with Chronic Urticaria (CU). This relationship may be due to the possible autoimmune etiology in up to one third of the cases of Chronic Idiopathic Urticaria (CIU). However, the frequency of ATD ranged from 1.14% to 28.6%. The study began by determining whether there is an association between ATD and CU, in a population seen at the same clinic. We compared the frequency of anti-thyroid antibodies and thyroid dysfunction in 49 patients with CIU (group 1) and 112 controls (group 2). In order to support the result found, we studied the prevalence of CIU in 60 patients with ATD (group 3) and compared with 29 patients who had non-immune thyroid disease (NITD) (group 4). We did not find a statistical difference for the presence of anti-thyroid antibodies or thyroid dysfunction between groups 1 and 2 (12.24% x 9.82% and 12.24% x 7.14%, respectively). The same occurred for the presence of CIU among groups 3 and 4 (3.33% x 3.44%). In our study it was not possible to demonstrate a relationship between ATD and CIU, which means that different populations may present a higher or lower degree of association between these illnesses.

    Thyroid autoimmune disease, a widespread phenomenon in female population, impairs thyroid function during pregnancy. Identifying cases, which will develop hypothyroidism during pregnancy, is crucial in the follow-up process. The study group comprised 108 females, with ages between 20-40 years; with known inactive autoimmune thyroid disease, before pregnancy that became pregnant in the study follow-up period. They were monitored by means of clinical, hormonal and immunological assays. Supplemental therapy with thyroid hormones was used, where needed. Maternal age and level of anti-thyroid antibodies were used to predict thyroid functional impairment.

    Full Text Available Autoimmune thyroid disease may occasionally associate with unspecific neurological symptoms, which are more commonly insidious, include cognitive or behavioural symptoms, and may associate with tremor, myoclonus, or ataxia. We report a 61-year-old female patient who presented with chronic headache, insidious mood, and cognitive disturbance which evolved in a few months to dementia associated with exuberant limb myoclonus. Diagnostic workup revealed high anti-thyroid peroxidase antibody titers and an inflammatory CSF profile, and it was negative for other possible etiologies. Treatment with steroids induced significant improvement. The diagnosis of encephalopathy associated with autoimmune thyroid disease is still controversial given the fact that the clinical presentation and diagnostic workup are unspecific, the pathophysiology is still undetermined, and the diagnosis is mostly of exclusion. No direct correlation is found between anti-thyroid antibody titers and clinical presentation, and it is currently speculated that other still unrecognized antibodies may be responsible for this clinical entity. It is extremely important to recognize this entity because it is potentially treatable with immunotherapies. It is also increasingly recognized that clinical improvement with first-line treatment with steroids may be absent or incomplete, and other immunotherapies as immunosuppressants, intravenous immunoglobulin, or plasma exchange must be attempted in the clinical suspicion of EEAT.

    Autoimmune thyroid disease may occasionally associate with unspecific neurological symptoms, which are more commonly insidious, include cognitive or behavioural symptoms, and may associate with tremor, myoclonus, or ataxia. We report a 61-year-old female patient who presented with chronic headache, insidious mood, and cognitive disturbance which evolved in a few months to dementia associated with exuberant limb myoclonus. Diagnostic workup revealed high anti-thyroid peroxidase antibody titers and an inflammatory CSF profile, and it was negative for other possible etiologies. Treatment with steroids induced significant improvement. The diagnosis of encephalopathy associated with autoimmune thyroid disease is still controversial given the fact that the clinical presentation and diagnostic workup are unspecific, the pathophysiology is still undetermined, and the diagnosis is mostly of exclusion. No direct correlation is found between anti-thyroid antibody titers and clinical presentation, and it is currently speculated that other still unrecognized antibodies may be responsible for this clinical entity. It is extremely important to recognize this entity because it is potentially treatable with immunotherapies. It is also increasingly recognized that clinical improvement with first-line treatment with steroids may be absent or incomplete, and other immunotherapies as immunosuppressants, intravenous immunoglobulin, or plasma exchange must be attempted in the clinical suspicion of EEAT.

    Physiological changes during gestation are important to be aware of in measurement and interpretation of thyroid function tests in women with autoimmune thyroid diseases. Thyroid autoimmune activity is decreasing in pregnancy. Measurement of serum TSH is the first-line screening variable for...... thyroid dysfunction also in pregnancy. However, using serum TSH for control of treatment of maternal thyroid autoimmunity infers a risk for compromised foetal development. Peripheral thyroid hormone values are highly different among laboratories, and there is a need for laboratory-specific gestational age......-related reference ranges. Equally important, the intraindividual variability of the thyroid hormone measurements is much narrower than the interindividual variation (reflecting the reference interval). The best laboratory assessment of thyroid function is a free thyroid hormone estimate combined with TSH...

    Full Text Available Hormones may play a role in the pathophysiology of vernal keratoconjunctivitis (VKC. An increased incidence of thyroid autoantibodies was recently observed in VKC, although there were no data on thyroid function. Two hundred and eighty-eight patients (202 males, 86 females; range 5.5 to 16.9 years with VKC were evaluated and compared with 188 normal age- and sex-matched subjects. In all subjects, serum concentrations of free T4, TSH, thyroperoxidase, thyroglobulin, and TSHr autoantibodies were evaluated. In VKC, the family history of thyroid diseases showed no significant differences compared to the controls (9.4 versus 8.6%, whereas the family history of autoimmune diseases was significantly higher (13.2% versus 6.3%; P<0.05. Subclinical hypothyroidism was diagnosed in 6.6% (versus 1.6% of the controls; P<0.05 and overt hypothyroidism in 0.7% (versus 0.0% of the controls; P=NS. Finally, 5.2% of patients were positive for thyroid autoantibodies, which were significantly higher with respect to the controls (0.5%, P<0.05. In the patients positive for thyroid autoantibodies, 80% showed a sonography pattern that suggested autoimmune thyroiditis. Thyroid function and autoimmunity abnormalities are frequently present in children with VKC. Children with VKC should be screened for thyroid function and evaluated for thyroid autoimmunity.

    Full Text Available Malignant tumors of the thyroid gland account for about 1% of thenewly diagnosed malignant tumors each year, and their incidence inwomen is twice the incidence in men. According to the WHO classification (2004 thyroid tumors are divided into: carcinoma of the thyroid, adenoma and similar tumors, and other thyroid tumors which include: teratomas, angiosarcomas, paragangliomas and others, as well as primary lymphomas and plasmacytomas. Primary thyroid lymphomasare defined as lymphomas which originate in the thyroid gland. This study presents the case of a 68-year-old patient with a thyroid lymphoma, which caused compression of the airways. In the patientpresented there was reduced activity of the thyroid gland. The dominant symptoms were: breathing difficulties, hoarse voice and the enlargement of the thyroid. An ultrasound examination was performedbefore surgery on the neck, which showed a multinodular thyroid,with compromised and compressed trachea to the right and rear. Anemergency surgical procedure was performed to reduce the tumor.Pathohistological diagnosis confirmed diffuse large B cell lymphoma.The aim of the study was to present a patient with a thyroid lymphoma, who had previously not had any immunological changes to the gland,that is, she had not had any chronic lymphocyte thyroiditis, but due to the compressive syndrome it was necessary to perform an emergencysurgical procedure to reduce the tumor.

  17. Frequency of autoimmune thyroid disease in chronic urticaria

    International Nuclear Information System (INIS)

    To determine the frequency of autoimmune thyroid disease in diagnosed cases of chronic urticaria (CU) and the association between hypothyroidism and chronic urticaria if any. Study Design: Non-interventional, descriptive study. Place and Duration of Study: Department of Physiology, Dow University of Health Sciences, Karachi, from December 2004 to January 2006. Methodology: The patients were selected from Department of Dermatology and Medical Units of Civil Hospital, Jinnah Postgraduate Medical Centre, the Aga Khan Hospital and community clinics. A total number of 60 patients were enrolled in this study. In all patients, serum antithyroid autoantibodies (anti thyroglobulin and anti microsomal/thyroperoxidase), thyroid profile (serum TSH, T3 and FT4), complete blood count, erythrocyte sedimentation rate and IgE levels were carried out. The proportions were compared using chi-square test with significance at p < 0.05. Results: Forty seven (78%) patients were found to have chronic urticaria (history and laboratory reports). Out of 47 patients with diagnosis of CU, elevated titres of anti thyroglobulin (TGA) and anti microsomal antibodies (TMA) were found to be present in 20 (42.6%) and 27 (57.4%) patients respectively. Serum TSH level (thyroid stimulating hormone) was increased and T3, FT4 were decreased in 20 (42.6%) patients (p < 0.001). A total number of 20 (42.5%) patients were found to be hypothyroid with chronic urticaria of greater than 6 weeks duration. Conclusion: This study shows a statistically significant association between hypothyroidism and chronic urticaria. Full thyroid profile (serum thyroid autoantibodies, serum TSH, T3 and FT4) is highly recommended in patients with diagnosis of chronic urticaria. (author)

  18. Interferin with thyroid scintigraphy: the effects of interferon alpha induced thyroid gland autoimmunity and dysfunction upon thyroid scintigraphy in patients with the hepatitis C virus

    International Nuclear Information System (INIS)

    Full text: The incidence of hepatitis C virus (HCV) infection is increasing. Interferon alpha therapy is often used to treat patients who are HCV positive. Thyroid gland autoimmunity and dysfunction has been reported to occur with variable frequency during INF-alpha therapy in patients with the HCV. This study reviews the scintigraphic findings of thyroid scans in such patients in order to assess for the effects on thyroid scintigraphy. To our knowledge, there has been no comprehensive study of this important occurrence to date. There were a number of patients with the HCV being treated at our institution between 23/09/1996 and 09/08/2000. Some of them received INF-alpha therapy, certain were subsequently diagnosed with thyroid gland autoimmunity and/or dysfunction. Eight were imaged with thyroid scintigraphy and reviewed. The scintigraphic findings in the 8 patients fell into two broad categories; 4 demonstrated changes of Graves' disease, and 3 changes of thyroiditis (1 of these was sub-acute). One hypothyroid patient with anti-thyroglobulin antibodies had normal thyroid scintigraphy. Six patients were found to have antithyroid antibodies. One patient with thyroiditis tested negative to antithyroid antibodies. One patient was not tested for antithyroid antibodies. Interferon alpha induced thyroid gland autoimmunity and/or dysfunction can markedly affect the thyroid scintigraphic findings of patients with the hepatitis C virus. This hitherto undescribed occurrence on thyroid scintigraphy has important practical implications of which Nuclear Medicine Specialists need to be aware in order to correctly interpret thyroid scintigraphy studies in such patients. The clinical presentation and effects on imaging appearances are varied. The Nuclear Medicine Specialist can play a central role in establishing the causal link. Awareness of this occurrence enables the Nuclear Medicine Specialist to add value to the referral. This occurrence will become an increasingly common

    Full Text Available Introduction: There are many adverse effects that have been described for isotretinoin. To the best of our knowledge, this is the first report of a possible association of oral isotretinoin intake with autoimmune thyroiditis and ocular myasthenia gravis (OMG. Case Presentation: A 19-year-old Caucasian male, who had used oral isotretinoin for severe acne disease for the previous six months, was referred to our clinic. He had a three-week history of diplopia and variable bilateral ptosis. Physical examination showed moderate periorbital edema and limitations of up- and down-gaze in the left eye. Laboratory findings and thyroid ultrasound were consistent with autoimmune thyroiditis. Antithyroid therapy did not relieve the clinical symptoms. Concomitant OMG was suspected. Variable ptosis and a positive response to oral prednisolone of 40 mg/day and pyridostigmine of 360 mg/day supported the diagnosis of concomitant autoimmune thyroiditis and OMG. Conclusion: Autoimmune disorders may be triggered by oral isotretinoin treatment. Clinicians prescribing isotretinoin should be aware of the possible association between isotretinoin intake and concomitant autoimmune thyroiditis and OMG.

    To characterize the nature of thyroid peroxidase (TPO) autoantibodies present in the sera of patients with autoimmune thyroid disease, we cloned three IgG1/kappa Fab fragments which bind 125I-TPO. This was accomplished by the molecular cloning and expression in bacteria of IgG gene fragments from B cells infiltrating the thyroid of a patient with Graves' disease. The three Fab fragments (SP2, SP4, and SP5) are coded for by a common heavy chain (VH1, D, JH3) and three related, but different, l...

Bearing in mind the currently prevailing lack of consensus on the most appropriate nomenclature and diagnostic criteria for this condition and the implications that this lack undeniably has on clinical practice, it is obvious that an international and multidisciplinary agreement among clinicians should arrive at the most appropriate definition and terminology of encephalopathy occurring in patients with autoimmune thyroid disease. Concomitantly, efforts must be made to uncover the pathogenetic link between thyroid autoimmunity and the occurrence of encephalopathy.

    Full Text Available Peroxisome proliferator-activated receptor- (PPAR- γ expression has been shown in thyroid tissue from patients with thyroiditis or Graves’ disease and furthermore in the orbital tissue of patients with Graves’ ophthalmopathy (GO, such as in extraocular muscle cells. An increasing body of evidence shows the importance of the (C-X-C motif receptor 3 (CXCR3 and cognate chemokines (C-X-C motif ligand (CXCL9, CXCL10, and CXCL11, in the T helper 1 immune response and in inflammatory diseases such as thyroid autoimmune disorders. PPAR-γ agonists show a strong inhibitory effect on the expression and release of CXCR3 chemokines, in vitro, in various kinds of cells, such as thyrocytes, and in orbital fibroblasts, preadipocytes, and myoblasts from patients with GO. Recently, it has been demonstrated that rosiglitazone is involved in a higher risk of heart failure, stroke, and all-cause mortality in old patients. On the contrary, pioglitazone has not shown these effects until now; this favors pioglitazone for a possible use in patients with thyroid autoimmunity. However, further studies are ongoing to explore the use of new PPAR-γ agonists in the treatment of thyroid autoimmune disorders.

Overall, it is likely that the ophthalmopathy associated with Graves' hyperthyroidism is the same disease as that observed in patients – such as those reported here – in whom thyroid dysfunction and thyroid autoimmunity are not present during the period of follow-up. The role of autoimmunity against the TSH-r in euthyroid patients with ophthalmopathy has not been proven and the significance of the orbital antibodies is unclear.Keywords: ophthalmopathy, thyroid eye disease, collagen XIII, calsequestrin, euthyroid Graves' disease

    BACKGROUND: The encephalopathy associated with autoimmune thyroid disease (EAATD) is characterized by neurological\\/psychiatric symptoms, high levels of anti-thyroid antibodies, increased cerebrospinal fluid protein concentration, non-specific electroencephalogram abnormalities, and responsiveness to the corticosteroid treatment in patients with an autoimmune thyroid disease. Almost all EAATD patients are affected by Hashimoto\\'s thyroiditis (HT), although fourteen EAATD patients with Graves\\' disease (GD) have been also reported. METHODS: We have recorded and analyzed the clinical, biological, radiological, and electrophysiological findings and the data on the therapeutic management of all GD patients with EAATD reported so far as well as the clinical outcomes in those followed-up in the long term. RESULTS: Twelve of the fourteen patients with EAATD and GD were women. The majority of GD patients with EAATD presented with mild hyperthyroidism at EAATD onset or shortly before it. Active anti-thyroid autoimmunity was detected in all cases. Most of the patients dramatically responded to corticosteroids. The long term clinical outcome was benign but EAATD can relapse, especially at the time of corticosteroid dose tapering or withdrawal. GD and HT patients with EAATD present with a similar clinical, biological, radiological, and electrophysiological picture and require an unaffected EAATD management. CONCLUSIONS: GD and HT equally represent the possible background condition for the development of EAATD, which should be considered in the differential diagnosis of all patients with encephalopathy of unknown origin and an autoimmune thyroid disease, regardless of the nature of the underlying autoimmune thyroid disease.

    Environmental factors can play an important role in the development of autoimmune thyroiditis (AT) and other autoimmune diseases. This article reviews the role of heavy metals and infectious agents in AT. Currently, the genes responsible for a metal-induced pathology are known in experimental animals but similar knowledge is lacking in man. Metals such as nickel or mercury induce delayed type T cell hypersensitivity (allergy) which is relatively common, especially in women. T-cell allergy can be studied with the lymphocyte transformation test, LTT-MELISA. It has been found that patients with AT and other autoimmune diseases, such as multiple sclerosis, psoriasis, systemic lupus erythematosus and atopic eczema, show increased lymphocyte reactivity in vitro to inorganic mercury, nickel and other metals compared to healthy controls. The important source of mercury is dental amalgam. Replacement of amalgam in mercury-allergic subjects resulted in improvement of health in about 70% of patients. Several laboratory parameters such as mercury-specific lymphocyte responses in vitro and anti-thyroid autoantibodies were normalized as well. In contrast, no changes in health and laboratory results were observed in mercury-allergic patients who did not have their amalgams replaced. The same was true for non-allergic patients who underwent amalgam replacement. Infectious agents such as Helicobacter pylori (Hp) may cause chronic inflammation and autoimmune reactivity in susceptible subjects. The results of in vitro experiments performed with lymphocytes from Hp infected patients indicate that Hp can cause immunosuppression which might be eliminated by successful eradication therapy. In conclusion, heavy metals and Hp infection may play an important role in AT. Laboratory tests, such as LTT-MELISA, can help to determine the specific etiological agents causing inflammation in individual patients. The treatment of AT and other autoimmune diseases might be improved if such agents are

    Autoimmune thyroiditis (AIT) is one of the most common autoimmune diseases; genetic as well as environmental factors contribute to its pathogenesis. The thyroid is the organ with the highest selenium content per unit weight. Selenium status appears to have an impact on the development of thyroid pathologies. We investigated a possible difference of selenium serum levels as a marker of nutritional selenium supply between patients with AIT in central Lower Austria and a matched group of healthy persons living in the same region. Selenium serum levels in the patients with AIT were 98.0 ± 15.6 μg/l. A significant difference to the matched group of normal persons, whose selenium serum levels were 103.2 ± 12.4 μg/l, could not be detected by the t-test (p>0.05). We considered the serum selenium levels to be indicators of selenium supply (by alimentation). A serum level of 120-160 μg/l of selenium represents the normal range. According to this, most patients and control persons showed mild to moderate selenium deficiency (80-120 μg/l selenium). Although our data present slightly higher selenium levels in normal persons than in patients with AIT, this weak and statistically insignificant trend is not sufficient to support the conclusion of a link between inadequate selenium supply and autoimmune thyroid disease.

    Introduction: The prevalence of autoimmune thyroid disease (AITD) is 10–12% in the general population worldwide. Among various disorders co-existing with AITD, the concomitance of celiac disease (CD) with AITD results in poor absorption of thyroid medications and results in higher doses of the same. Institution of gluten-free diet (GFD) in this cohort helps reduce medication doses. Aim: To screen patients with AITD for the presence of celiac autoimmunity (CA). Materials and Methods: A total of 280 consecutive patients with AITD attending the thyroid Out-patient Department of a tertiary care hospital were screened for the presence of tissue transglutaminase antibodies (immunoglobulin A tissue transglutaminase). Those with a positive titer (but duodenal mucosal biopsy for the diagnosis of CD, followed by institution of GFD in confirmed cases. Results: Of a total of 280 (182 females and 98 males) patients with AITD screened, 24 (8.6%) turned out to be positive for CA. Of 24 (8.6%), 15 (8.24%) females and 9 (9.18%) males were positive for CA. There was no statistically significant difference in the thyroxine doses required for normalization of thyroid function and the weight of the patients in CA positive and CA negative patients. Conclusions: The prevalence of CD in patients with AITD is much greater than in the general population. This forms the basis for screening patients with AITD for presence of CD. PMID:26904476

    Vitamin D deficiency (levels lower than 20 ng/ml) is becoming a global health problem, since it is increasingly represented even among healthy subjects. Vitamin D, as an environmental factor, is involved in many biological processes, like perception of chronic pain and response to infections. In recent years, evidence has emerged pointing to an involvement of vitamin D in the development of many autoimmune diseases, and a severe vitamin D deficiency has been especially demonstrated in patients affected with autoimmune thyroid disease (AITD). Low levels of vitamin D were found associated with antithyroid antibody presence, abnormal thyroid function, increased thyroid volume, increased TSH levels, and adverse pregnancy outcome in women with AITD. Vitamin D mediates its effect through binding to vitamin D receptor (VDR), which is harbored on many human immune cells, and in this way is able to modulate immune cells activity, triggering both innate and adaptive immune responses. As VDR gene polymorphisms were found to associate with AITD, the evidence links vitamin D deficiency to AITD either through gene polymorphism or by environmental factors (lack of dietary uptake and sun exposure). Vitamin D supplementation may be offered to AITD patients, but further research is needed to define whether it should be introduced in clinical practice. PMID:25407646

    Thyroid associated ophthalmopathy, or thyroid eye disease (TED), is a complex inflammatory disorder of the eye that, as its name implies, is usually associated with thyroid disease. Clinical observation supports the existence of three main TED subtypes, namely ocular myopathy, congestive myopathy, and mixed congestive and myopathic ophthalmopathy. Although the precise pathophysiology of TED remains unclear, it is likely to reflect an autoimmune reaction involving sensitised T lymphocytes and autoantibodies directed against a specific orbital or thyroid-and-orbital shared antigen(s). One well-studied candidate in this immune reaction is the thyroid-stimulating hormone receptor (TSHR), which is also expressed in the orbital fibroblast and preadipocyte. Most patients with ophthalmopathy have associated Graves' disease, 10% have Hashimoto's thyroiditis in which the eye changes are often mild and expressed mainly as upper eyelid retraction (UER), and 10% have no apparent associated thyroid disease - so-called "euthyroid Graves' disease". Ophthalmopathy can also occur in some patients with transient thyroiditis, thyroid cancer, and Graves' disease many years after treatment of the hyperthyroidism - situations where TSHR antibodies are not expected to be present, suggesting that the relationship between TSHR antibodies and the eye disorder has not been established for all cases. In our studies of TED we have investigated the nature and significance of antibodies targeting other eye muscle and orbital connective tissue (OCT) antigens, in particular the calcium binding protein calsequestrin (CASQ1) and the orbital fibroblast membrane antigen collagen XIII. Our working hypotheses for the pathogenesis of TED are: i) the initial reaction in the orbit is antibody and T lymphocyte targeting of the TSHR in the OCT compartment, and ii) the associated extra ocular and upper eyelid muscle inflammation reflects either autoimmunity against primary skeletal muscle antigens such as CASQ

    The thyroid glands of patients with autoimmune diseases such as Graves' disease and certain forms of goiter contain infiltrating activated T lymphocytes and, unlike cells of normal glands, the epithelial follicular cells strongly express histocompatability antigens of the HLA-DR type. In a study of such autoimmune disorders, the infiltrating T cells from the thyroid glands of two patients with Graves' disease were cloned in mitogen-free interleukin-2 (T-cell growth factor). The clones were expanded and their specificity was tested. Three types of clones were found. One group, of T4 phenotype, specifically recognized autologous thyroid cells. Another, also of T4 phenotype, recognized autologous thyroid or blood cells and thus responded positively in the autologous mixed lymphocyte reaction. Other clones derived from cells that were activated in vivo were of no known specificity. These clones provide a model of a human autoimmune disease and their analysis should clarify mechanisms of pathogenesis and provide clues to abrogating these undesirable immune responses.

    Background Thyroid autoimmunity has been increasingly reported to be associated with chronic urticaria (CU), and the possible clinical benefit of thyroid hormone or anti-thyroid drugs in some CU patients with autoimmune thyroid disease has been studied. However, the effect of thyroid hormone or anti-thyroid drugs on clinical symptoms of CU remains unclear. Objective We investigated the clinical response of urticaria to the treatment of thyroid dysfunction. Methods Medical records of patients with CU evaluated for thyroid autoimmunity and thyroid function were collected and reviewed. Results Of 184 patients with CU, 43 patients (23.4%) had thyroid autoantibodies and 26 patients (14.1%) had thyroid dysfunction. While none of the five patients with Graves' disease showed any improvement of urticaria after treatment with anti-thyroid drugs, two of the 10 patients with Hashimoto's thyroiditis showed improved urticaria after being treated with levothyroxine. Conclusion Although levothyroxine treatment was effective in a minority of patients with CU, there may be a causal relationship between CU and thyroid autoimmunity. PMID:27081267

    Full Text Available Abstract Background The autoimmune thyroid diseases (AITDs, comprising Graves' disease (GD and Hashimoto's thyroiditis (HT, appear to develop as a result of complex interactions between predisposing genes and environmental triggers. Susceptibility to AITDs is conferred by genes in the human leukocyte antigen (HLA and genes unlinked to HLA, including the CTLA-4 gene. Recently, an association to some estrogen receptor (ERα genotypes with breast cancer, hypertension, osteoporosis, generalized osteoarthritis, and some autoimmune diseases such as rheumatoid arthritis has been reported. We have analyzed a dinucleotide (TAn repeat polymorphism lying upstream of the human ERα gene in patients with AITDs and in normal subjects. Results Seventeen different alleles were found in 130 patients with GD, 93 patients with HT, and 190 control subjects. There was no significant difference in the distributions of ERα alleles between patients and controls. Conclusions The present results do not support an association between the ERα gene and AITD in the Japanese population.

    Full Text Available Abstract Background Children are commonly referred to a pediatric rheumatology center for the laboratory finding of an Anti-nuclear antibody (ANA of undetermined significance. Previous studies regarding adult rheumatology patients have supported an association between ANA and anti-thyroid antibodies, with the prevalence of thyroid antibodies being significantly higher in patients referred to a rheumatology center for an ANA without evidence of connective tissue disease compared to the general population. The purpose of the present study was to determine the frequency of thyroid antibodies in children referred to a pediatric rheumatology center for a positive ANA without evidence of a connective tissue disease. Methods A retrospective chart review was performed on children who were referred to our pediatric rheumatology center between August 2003 and March 2007 for positive ANA with concurrent thyroid antibody and thyroid function tests performed who did not fulfill criteria for a specific connective tissue disease. Laboratory and clinical features were recorded and analyzed. Mean and standard deviation were used to describe continuous data. Chi-square or Fisher's exact tests were used to compare proportions between variables. Results One-hundred and four ANA-positive patients with concurrent thyroid studies were evaluated (88% female, 93% Caucasian, mean age 11.9 ± 4.0 years. Half of patients had an ANA titer ≥ 1:320. The ANA pattern was speckled in 60% of the patients. Thyroid antibodies were detected in 30% of the patients. Anti-Thyroglobulin (ATG was detected in 29% and Anti-thyroid peroxidase (ATPO in 21% of the patients; of these children, 14% had hypothyroidism. ANA pattern and titer were not associated with anti-thyroid antibody positivity. Conclusion Thyroid antibodies associated with chronic lymphocytic thyroiditis, ATG and ATPO, were detected significantly higher in ANA-positive children without a rheumatologic condition (30% as

    To evaluate the association of gallium-67 ({sup 67}Ga)-citrate thyroid uptake with the presence of thyroid disorders in patients with sarcoidosis (S patients). Eighty-four S patients were evaluated by a complete thyroid work-up (neck ultrasound, circulating thyroid hormones and anti-thyroid antibodies, fine-needle aspiration). In S patients with {sup 67}Ga thyroid uptake (respect those without): serum thyroid-stimulating hormone, the titre of anti-thyroid peroxidase (AbTPO) and/or anti-thyroglobulin antibodies (AbTg), and the prevalence of S patients with hypothyroidism or with positive AbTg or AbTPO was significantly higher; a thyroid hypoechoic pattern was more frequent. The prevalence of thyroid nodules was not significantly different between the two groups. Two cases of papillary thyroid cancer were observed in S patients without {sup 67}Ga thyroid uptake, whilst no case in those with {sup 67}Ga thyroid uptake. {sup 67}Ga thyroid uptake is associated with the presence of aggressive autoimmune thyroiditis and hypothyroidism in S patients; thyroid function and ultrasonography should be performed in the presence of {sup 67}Ga thyroid uptake.

    CXC chemokine ligand 12 (CXCL12) and its receptor, CXC chemokine receptor 4 (CXCR4), are upregulated in mice with autoimmune thyroid diseases. However, whether this interaction is involved in the pathophysiology of autoimmune thyroiditis (AIT) remains to be elucidated. In the present study, the effects of the CXCR4 antagonist, AMD3100, in an iodine‑induced autoimmune thyroiditis model were investigated. NOD.H‑2h4 mice were randomly separated into a control, AIT and AIT+AMD3100 groups. The mice were fed with 0.05% sodium iodide water for 8 weeks to induce AIT. The AMD3100‑treated mice were administered with the CXCR4 antagonist at a dose of 10 mg/kg intraperitoneally three times a week during the experimental period. The percentages of CD19+interleukin (IL)10+ B cells and CD4+IL10+ T cells, and the mRNA expression levels of IL10 in the splenocytes were reduced in the AIT group, compared with the control group, however, they increased following AMD3100 treatment, compared with the untreated AIT group. The percentages of CD4+ T cells, CD8+ T cells, CD19+ B cells and CD8+ interferon (IFN)γ+ T cells, and the mRNA expression levels of IFNγ increased in the AIT group, compared with the control group, however, these were reduced in the AMD3100 group, compared with the AIT group. The AMD3100‑treated mice also had lower serum thyroglobulin antibody titers and reduced lymphocytic infiltration in the thyroid, compared with the untreated AIT mice. These results suggested that inhibition of this chemokine axis may offer potential as a therapeutic target for the treatment of AIT. PMID:26935473

  6. Study of the immune response to thyroglobulin through a model of experimental autoimmune thyroiditis

    International Nuclear Information System (INIS)

    The cellular and humoral immune response to thyroglobulin of different species was studied in guinea pigs. The experiments described suggested that the immune system can be activated against self-determinants. Human and pork thyroglobulin were able to induce the experimental thyroiditis as well as some immune responses, such as in vitro proliferative response, delayed hypersensitivity and antibodies. Although guinea pig thyroglobulin was unable to induce specific T-lymphocyte proliferation in vitro, delayed hypersensitivity response and antibodies, it was very efficient in inducing the autoimmune thyroiditis. On the contrary, bovine thyroglobulin did not induce experimental autoimmune thyroiditis despite producing good responses as determined by similar in vitro proliferative response, delayed hypersensitivity and on the humoral level. These results suggest that the assays utilised were not able to evaluate the relevant immune response to genesis of the thyroiditis. The determinant selection mechanisms operating in these immune responses are probably selecting determinants not responsible for self-recognition in vivo. It was suggested that the macrophage could be the cell responsible for the presentation of these determinants to the lymphocyte in an immunogenic form. (Author)

    Autoimmune lymphoproliferative syndrome (ALPS) is characterized clinically by chronic non-malignant lymphoproliferation and autoimmunity and is caused by a genetic defect in programmed cell death (apoptosis). Most patients with ALPS have heterozygous mutations in the Fas gene. We describe an 11-year-old Brazilian boy with hepatosplenomegaly, lymphadenopathy, hemolytic anemia, and hypergammaglobulinemia since early infancy. T cell lines from the patient were defective in Fas-mediated apoptosis. He was diagnosed as having ALPS and found to have a novel Fas gene mutation (IVS4+1G>A). In addition, he presented with glomerulonephritis in infancy. An aunt and uncle who had the same Fas mutations also had histories of glomerulonephritis. Although glomerulonephritis is common in Fas-deficient mice, it is infrequent in human ALPS. Corticosteroid therapy ameliorated the glomerulonephritis in our patient, as well as his lymphoproliferation, anemia, and hypergammaglobulinemia. This study suggests that glomerulonephritis is one of the characteristic features of ALPS. PMID:12736807

    Objective. To determine the prevalence and impact of autoimmune thyroid disease (AITD) in patients with rheumatoid arthritis (RA). Methods. Eight-hundred patients were included. The association between AITD and RA was analyzed was analyzed by bivariate and multivariate analysis. In addition, a literature review was done focusing on geographical variations. Results. In our cohort the prevalence of AITD was 9.8% while the presence of antibodies was 37.8% for antithyroperoxidase enzyme (TPOAb) and 20.8% for antithyroglobulin protein (TgAb). The presence of type 2 diabetes, thrombosis, abnormal body mass index, and a high educational level was positively associated with AITD. The literature review disclosed a geographical variation of AITD in RA ranging from 0.5% to 27%. Autoantibody prevalence ranges from 6% to 31% for TgAb, 5% to 37% for TPOAb, and from 11.4% to 32% for the presence of either of the two. Conclusion. AITD is not uncommon in RA and should be systematically assessed since it is a risk factor for developing diabetes and cardiovascular disease. These results may help to further study the common mechanisms of autoimmune diseases, to improve patients' outcome, and to define public health policies. An international consensus to accurately diagnose AITD is warranted. PMID:23209899

  9. Autoimmune thyroiditis goitrogenic. Aspects of clinical and laboratorial diagnostic

    International Nuclear Information System (INIS)

    To asses the accuracy achieved by the A.C.A.T. and other clinical and laboratorial criterion in the diagnoses of T.A.I.B. we investigated twenty patients with goiter and antimicrossomal antibodies titres of 1/1.600 or more. Analysing the parameters useful in the diagnosis, we found a significant correlation between the antimicrossomal antibodies titres and the basal TSH concentration, an elevated basal TSH and an exaggerated response to TRH independent of the patient clinical status reflecting in the majority of the cases a state of subclinical hypotyroidism; an irregular appearance of the radioisotope thyroid scan and a positive response to a perchlorate discharge test. We conclude that from the parameters useful in the T.A.I.B. diagnosis, the A.C.A.T. detection mainly the antimicrossomal antibodies, is an excellent tool to detect patients with a clinical suspect of thyroid auto-immune disease and when we found high tires in a patient with goiter and an elevated basal TSH concentration we can suggest T.A.I.B. diagnosis.

    OBJECTIVE: In euthyroid individuals, autoantibodies to thyroid peroxidase (TPOab) and thyroglobulin (Tgab) are regarded as early markers of thyroid autoimmunity. Family and twin studies suggest that development of thyroid autoantibodies in first-degree relatives of patients with autoimmune thyroid...... disease is under genetic influence. We aimed to estimate the relative importance of genetic and environmental effects for the presence of thyroid autoantibodies in euthyroid subjects. METHODS: A representative sample of healthy twin pairs was identified through the Danish Twin Registry; 1372 individuals...... concordance and intraclass correlations were consistently higher for MZ than for DZ twin pairs indicating genetic influence. Genetic components (with 95% confidence intervals) accounted for 73% (46-89%) of the liability of being thyroid antibody positive. Adjusting for covariates (age, TSH and others), the...

    Thyroid hemiagenesis (THA) is a rare abnormality characterized by the absence of one thyroid lobe. Elevated thyroid stimulating hormone (TSH) level and higher incidence of thyroid diseases were reported in THA. The aim of the study is to evaluate the thyroid autoimmunity incidence in patients with THA and influence of higher than average TSH level on thyroid volume (TV) and its change with age. The study included a group of naive patients with THA and a control group of subjects with bilobate thyroid. All patients underwent clinical examination, thyroid ultrasound, scintiscan and laboratory tests. In the studied and control group the presence of thyroid autoantibodies (TAb) was evaluated. The THA group consisted of 65 patients. In THA group 53.85 % of patients were positive for TAb. Patients with positive TAb were older (46.0 ± 18.3 years) than those with negative (35.0 ± 19.8 years); p = 0.02. The incidence of TAb was lower in controls (13.85 %, p volume and median TSH level were higher in patients with THA when compared to controls (13.60 vs 8.20 ml, p < 0.0001; 3.23 vs 1.48 µU/ml, p < 0.0001, respectively). Patients with THA constitute an in vivo model of long-term thyroid TSH overstimulation. Further studies are needed to reveal, whether TSH overstimulation may be the trigger for thyroid autoimmunity.

    Full Text Available It was revealed, that, in blood samples of the patients with autoimmune thyroid diseases, serum antibodies against cell-free fraction of Bifidobacterium bifidum 791 and Lactobacillus plantarum B-01 were detected, respectively, in 71 and 63% of cases, that being two-fold higher than appropriate frequencies in healthy blood donors. An evidence was obtained that presence of some components specifically reacting with autoantibodies against thyroid peroxidase and thyroglobulin on the surface of the microorganisms cells and competing for binding of these immunoglobulins with thyroid antigens. One may also suggest a presence of bacterial components, interacting with thyroid peroxidase. The data obtained let us suggest that probiotic microorganisms of Bifidobacterium and Lactobacillus genus could take part in pathogenesis of autoimmune thyroid diseases, by means of molecular mimicry mechanisms.

  15. Iodine Excess as an Environmental Risk Factor for Autoimmune Thyroid Disease

    2014-07-01

    Full Text Available The global effort to prevent iodine deficiency disorders through iodine supplementation, such as universal salt iodization, has achieved impressive progress during the last few decades. However, iodine excess, due to extensive environmental iodine exposure in addition to poor monitoring, is currently a more frequent occurrence than iodine deficiency. Iodine excess is a precipitating environmental factor in the development of autoimmune thyroid disease. Excessive amounts of iodide have been linked to the development of autoimmune thyroiditis in humans and animals, while intrathyroidal depletion of iodine prevents disease in animal strains susceptible to severe thyroiditis. Although the mechanisms by which iodide induces thyroiditis are still unclear, several mechanisms have been proposed: (1 excess iodine induces the production of cytokines and chemokines that can recruit immunocompetent cells to the thyroid; (2 processing excess iodine in thyroid epithelial cells may result in elevated levels of oxidative stress, leading to harmful lipid oxidation and thyroid tissue injuries; and (3 iodine incorporation in the protein chain of thyroglobulin may augment the antigenicity of this molecule. This review will summarize the current knowledge regarding excess iodide as an environmental toxicant and relate it to the development of autoimmune thyroid disease.

    Full Text Available Abstract Background The so called “big-big” prolactin (Prl, also known as macroprolactin is formed by Prl-immunoglobulin (Prl-IgG complexes and may cause elevation of serum Prl concentrations measured by standard assays, potentially leading to unnecessary investigations and/or treatment. In our study, we have endeavoured to assess the prevalence of macroprolactinaemia in euthyroid, regularly menstruating women with thyroid disease, as well as to assess whether autoimmune thyroid disease may result in an increased prevalence of macroprolactinaemia. Material and methods We measured serum Prl in 182 regularly menstruating women aged 32.7 ± 7.5 years (mean ± SD, range 17–46 years who attended endocrine clinic either for investigation of non-toxic goitre (n = 86, age 33.2 ± 7.8 years or with autoimmune thyroid disease (n = 96, age 32.3 ± 7.2 years. Autoimmune thyroid disease was defined as raised titre of at least one anti-thyroid antibody [anti-thyroid peroxidase (anti-TPO, anti-thyroglobulin (anti-Tg and/or anti-TSH-receptor (anti-TSH-R antibodies]. All women were clinically and biochemically euthyroid, either without or on treatment with L-thyroxine. In those with raised Prl (i.e., above 530 mIU/l we ruled out the presence of macroprolactinaemia by polyethylene glycol (PEG precipitation method. Results There was no significant age difference between women with and without autoimmune thyroid disease (p = 0.84. Raised Prl concentrations were found in 10 women with thyroid disease (5.5%, and of those a significant macroprolactinaemia (i.e., reduction of Prl concentrations of more than 60% after PEG precipitation was found in 9 subjects (4.94%. There were no differences in the prevalence of macroprolactinaemia between women with autoimmune thyroid disease (4 out of 96, and without autoimmune thyroid disease (5 out of 86, p = 0.75. Conclusions Approximately one out of twenty women with regular menses is likely

  18. Is vitamin D a player or not in the pathophysiology of autoimmune thyroid diseases?

    2015-05-01

    1,25-Dihydroxyvitamin D is a steroid hormone derived from vitamin D, playing an important role in maintaining an adequate serum level of calcium and phosphorus. It is now clear that vitamin D exerts an endocrine action on the cells of the immune system, generating anti-inflammatory and immunoregulatory effects. The mechanisms underlying the role of vitamin D in autoimmunity are not completely understood. Lower vitamin D levels have been found in several autoimmune diseases, such as rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, type 1 diabetes mellitus, multiple sclerosis, inflammatory bowel diseases, autoimmune thyroid diseases (i.e. Hashimoto's thyroiditis and Graves' disease) and autoimmune gastritis. Several genetic studies have demonstrated an association between thyroid autoimmunity susceptibility and gene polymorphisms of vitamin D receptor, vitamin D binding protein, 1-alpha-hydroxylase and 25-hydroxylase. Of note, some papers do not confirm this connection. With regard to the role of vitamin D in autoimmune thyroid diseases, available data remain controversial. Only few reports have analyzed the supposed association between autoimmune thyroid diseases and vitamin D concentration with inconclusive results. In our experience, low serum levels of vitamin D do not correlate either with Hashimoto's thyroiditis or with Graves' disease. The inability to achieve an unambiguous conclusion is in part due to the limitations in study design. In fact, most of the studies are cross-sectional surveys with a small number of subjects. In addition, the heterogeneity of the study population, seasonal variation of blood sampling, inter-method analytical variability of vitamin D assays and different definitions of vitamin D deficiency/insufficiency contribute to contradicting results. Therefore, further randomized, controlled, prospective trials are needed in order to demonstrate the causality of vitD in AITD and consequently the role of vitamin D

    Background: Autoimmune thyroid diseases (ATDs) are the most common endocrine diseases which result in rheumatologic manifestations. Some studies have shown association between rheumatologic disorders and ATDs. Thus, the aim of this study was to assess the frequency of rheumatologic manifestations in patients with ATDs. Materials and Methods: In this cross-sectional descriptive study during 2010 to 2011, 65 patients with ATDs referred to the Rheumatology clinic of 5 Azar Hospital in Gorgan (North of Iran) were studied via systematic random sampling and patients with positive antithyroid peroxides (anti-TPO) were included in the study. These patients were examined by a rheumatologist for diagnosis of rheumatologic manifestations and tested for serum levels of TSH, Free T3 and T4, Anti-Nuclear Antibodies (ANAs) and Rheumatoid Factor (RF). SPSS software (version 16) and descriptive statistics were used for data analysis. Results: Nine males (14.8%) and 56 females (86.2%) with mean age of 38.81±1.44 years were studied. Overall, Rheumatologic manifestations were seen in 86.2 % (n=56). In this study, the most frequent rheumatologic manifestations were Carpal Tunnel Syndrome (36.1%) and Osteoarthritis (23%). Reynaud’s phenomenon (RP) (10.7%), Discopathy (8.9%), Fibromyalgia (5.3%), Myopathy (3.6%), Rheumatoid arthritis (3.6%) and trigger finger (3.6%) were other manifestations, respectively. Conclusion: In this region, there is a high frequency of rheumatologic manifestations in patients with ATDs. Thus, initial evaluation and regular checkings are recommended. PMID:25478383

    Full Text Available Background: There is a clear association between autoimmune thyroiditis (AT and chronic urticaria/angioedema (CUA. However, not all patients with AT demonstrate urticaria. Aims: The aim of the study was to investigate in which patients with AT did CUA become a problem. A sensitive inflammation marker, neopterine (NP was used to confirm whether the severity of inflammation in the thyroid gland was responsible for urticaria or not. Methods: Neopterine levels were assessed in patients with AT with urticaria and without urticaria. Furthermore, levels were compared in relation to pre and post levothyroxine treatment. Twenty-seven patients with urticaria (Group 1 and 28 patients without urticaria (Group 2 were enrolled in the study. A course of levothyroxine treatment was given to all patients, and urine neopterine levels before and after the trial were obtained. Results: All patients completed the trial. Mean age in Group 1 and Group 2 was similar (35.70 ± 10.86 years and 38.36 ± 10.38 years, respectively (P=0.358. Pre-treatment urine neopterine levels were significantly higher in Group 1 (P=0.012. Post-treatment levels decreased in each group, as expected. However, the decrease in the neopterine level was insignificant in the patients of Group 2 (P=0.282. In Group 1, a significant decrease in post-treatment neopterine levels (P=0.015 was associated with the remission of urticaria. Conclusion: In patients with CUA and AT, pre-treatment elevated levels of NP, and its decrease with levothyroxine treatment along with symptomatic relief in urticaria, may be evidence of the relationship between the degree of inflammation in thyroid and presence of urticaria.

    Autoimmune disorders are known to be more frequent in women and often associated each others, but it is rare to see multiple autoimmune diseases in a single patient. Recently, the concept of multiple autoimmune syndrome has been introduced to describe patients with at least three autoimmune diseases. We describe a case of a young man with a clinical history of psychiatric symptoms and celiac disease (CD) who was diagnosed to have other two autoimmune disorders: systemic lupus erythematosus (SLE) and Hashimoto's thyroiditis. This case is unusual upon different patterns: the rare combination of the three autoimmune diseases, their appearance in a man and the atypical onset of the diseases with psychiatric symptoms likely to be related either to CD or to SLE.

  2. The clinical value of detection of serum TGAb and TPOAb level in autoimmune thyroid diseases

    International Nuclear Information System (INIS)

    To study the clinical value of serum TGAb and TPOAb levels in the diagnosis of patients with autoimmune thyroid diseases (AITD), the serum levels of TGAb and TPOAb in 175 patients with AITD and 64 non-AITD patients and 57 health controls were measured by RIA. The results showed that the serum levels of TGAb and TPOAb in AITD patients with GD and HT were significantly higher than that of control group (P0.05). The detection of serum TGAb and TPOAb levels may have clinical value in the diagnosis, treatment and prognosis of autoimmune thyroid diseases. (authors)

    Full Text Available Hooshang Lahooti, Kishan R Parmar, Jack R WallThe Department of Medicine, University of Sydney, Nepean Clinical School, Penrith, NSW, AustraliaAbstract: Thyroid-associated ophthalmopathy (TAO, or thyroid eye disease, is a complex inflammatory disorder of the eye that, as its name implies, is associated with thyroid disease. TAO can be divided into three subtypes: ocular myopathy, congestive myopathy and mixed congestive and myopathic ophthalmopathy. Although the precise pathophysiology of TAO remains unclear it is likely to reflect an autoimmune reaction involving sensitized T-cells and autoantibodies directed against a thyroid and orbital tissue shared antigen. One well studied candidate in this immune reaction is the thyroid-stimulating hormone receptor (TSH-r, expressed in the orbital fibroblast and pre adipocyte. In our studies of TAO, we have investigated the nature and significance of antibodies targeting other eye muscle and orbital connective tissue (OCT antigens. Our findings suggest that autoimmunity against the eye muscle antigen calsequestrin and the OCT antigen collagen XIII plays a role in the pathogenesis of TAO. We propose that ocular myopathy and chronic eyelid retraction are due to autoimmunity against skeletal muscle calsequestrin in the extraocular and eyelid muscles, respectively. This may be initiated in the thyroid where calsequestrin expression is upregulated, possibly due to a stimulatory effect of TSH-r antibodies. We also propose that congestive ophthalmopathy results from a reaction against the TSH-r or collagen XIII in orbital fibroblast cell membranes. Further insight into the role of eye muscle and OCT antigens in the pathogenesis of TAO may allow for the development of new therapies to treat the eye disorder and reduce patient morbidity.Keywords: thyroid-associated ophthalmopathy, autoimmunity, t calsequestrin, collagen XIII

    Background Chronic autoimmune thyroiditis, manifested by positive test for antithyroid antibodies, is common in the general population, occurring in 10 to 20 percent of women. The aim of the study was to determine whether Anti-TPO is more prevalent in women with ACTD, compared to the general population. Methods Anti-TPO was determined in 290 women diagnosed with ACTD based on ACR (American College of Rheumatology) criteria and in 50 healthy women (control group). Among ACTD patients, 121 were diagnosed with Rheumatoid Arthritis (RA), 44 Systemic Lupus Erythematosus (SLE), 43 Sjοgren's Syndrome (SS), 42 Systemic Scleroderma (SScl) and 40 Psoriatic Arthritis (PsA). Anti-TPO was measured by Chemiluminescent Microparticle Immunoassay (CMIA) on Architect i2000SR (ABBOT Laboratories). Results The prevalence of Anti-TPO in separate groups of patients had as follow: RA 28.93%, SLE 29.55%, SS 27.91%, SScl 23.81%, PsA 30% and control group 12%. Conclusions ACTD and thyroid autoimmune diseases often overlap with each other. Increased Anti-TPO may be most common among women patients with ACTD. On the other hand, these systemic diseases are often present in Hasimoto's thyroiditis subjects. Therefore it is clinically important to screen women patients with ACTD for the co-existence of thyroid disorders.

  15. The diagnostic value of Th1/Th2 cell cytokine and thyroid autoantibody on autoimmune thyroid diseases

    International Nuclear Information System (INIS)

    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)

    For a better understanding of the pathogenesis of thyroid autoimmune diseases, we have studied morphological and functional properties of T clones from peripheral blood lymphocytes (PBL) and from intrathyroidal lymphocytes (ITL) obtained from 3 patients with Graves' disease or 1 Hashimoto's thyroiditis. Investigations were carried out on clones cultured alone or cocultured with autologous thyrocytes. Clonage efficiency ranged from 30% to 33% for PBL and 10% to 36% for ITL. A predominance of CD4-positive clones was observed whatever the origin of the lymphocytes or the autoimmune pathology. Gamma interferon (IFN-gamma) was detected in the majority (17/19) of the clones tested. Intracytoplasmic interleukin (IL-4) was secreted in 7/19 clones and both cytokines were produced in 5/19 clones. In coculture a proliferative response and tumour necrosis factor (TNF-alpha) production were observed with 6 clones (4 from Graves thyrocytes and 2 from thyroiditis). No cytotoxic clone was derived from Graves or thyroiditis tissues. These data demonstrate that the large majority of T clones are principally CD4-T cells; all the clones secreted TNF-alpha and a large majority produced IFN-gamma. Only a few clones produced IL-4 alone or associated with IFN-gamma. Six T clones induced proliferative response and of TNF-alpha secretion in coculture. Further investigations must be performed on these antigen-reactive T clones to analyse their role in the pathogenesis of the human thyroid autoimmune diseases. PMID:10739333

    Full Text Available The aim of the investigation is to study the state of arteries of elastic and muscular type in patients with autoimmune thyroiditis and subclinical hypothyroidism to reveal potential factors of cardiovascular risk. Materials and Methods. There have been studied three groups of patients, each group consisting of 29 females: 1st — control group, with no abnormalities, 2nd — with autoimmune thyroiditis and euthyroid status, 3rd — with autoimmune thyroiditis and subclinical hypothyroidism. There have been estimated hormonal status (ТТГ, Т4, Т3, antibody level to thyroglobulin and thyroid peroxydase, endothelial function and arterial stiffness. Results. In subclinical hypothyroidism there is significant decrease of endothelial function of brachial artery, with normal indices of non-endothelium dependent vasodilation; arterial wall stiffness and endothelial dysfunction increase, that is determined by a number of factors including the levels of T3, T4, thyrotropic hormone, lipid profile, and arterial pressure. The level of systemic arterial pressure can be of great concern in the increase of arterial stiffness if there are no marked changes of lipid spectrum. The obtained data indicate the negative effect of even minimal thyroid function on vessel condition that can contribute to the increase of cardiovascular risk along with lipid spectrum disorders in this group of patients.

  18. Signs of autoimmune thyroiditis in children and juveniles affected by the Chernobyl accident

    International Nuclear Information System (INIS)

    The content of antibodies to human thyroid microsomal antigen was investigated to evaluate the possible appearance of autoimmune thyroiditis in children and juveniles living in the areas of Kaluga region affected by the Chernobyl accident. The percentage of positive sera varied from 4.8% to 1.2% over seven years. There is a significant difference in the frequency of antibody appearance between persons affected by radioactive iodine and those not affected. A greater quantity of the positive sera was recorded in the area with highest level of radioactive contamination. It is suggested that the elevated rate of autoimmune thyroiditis signs in children and juveniles is one of the consequences of the Chernobyl accident. (Author)

  19. Color Doppler measurement of blood flow in the inferior thyroid artery in patients with autoimmune thyroid diseases

    International Nuclear Information System (INIS)

    Purpose: The aim of the study is to find out whether the measurement of peak systolic velocity in the inferior thyroid artery (ITA) is a valuable parameter to differentiate autoimmune thyroid diseases (hyper-, normo- or hypofunctional) and to evaluate the efficacy of medical treatment. Material and methods: The ITA of 31 patients (eight with Graves' disease, 23 with subclinical hypothyroidism) was examined with color Doppler and pulsed Doppler. The final diagnosis was obtained by citology and by hormonal and antibodies assays. The patients were monitorized by ultrasound for a period of 8 months. Results: In all the patients with Graves' disease the peak systolic velocity was always over 150 cm/s, while in other autoimmune thyroiditis the peak systolic velocity was within the normal range, and never exceeding 65 cm/s. In the first group, the measurement taken in the ITA showed also the efficacy of the pharmacological treatment earlier and more reliably than the color Doppler pattern obtained in the parenchyma. Conclusions: The color Doppler measurement of the ITA seems to be a promising technique with low-cost and easy approach. In our experience, the color Doppler of the ITA could have a clinical role in the differential diagnosis of diffuse thyroid diseases and in the follow-up of the Graves' disease during medical treatment

    To investigate the relationships between lymphocyte subsets and thyroid function, peripheral blood lymphocytes were analysed with cell surface antigens of activated (HLA-DR+) T, helper T (CD4+ 2H4-, CD4+ 4B4+) and suppressor-inducer T (CD4+ 2H4+, CD4+ 4B4-) cells subsets in 56 patients with Graves' disease, 16 patients with Hashimoto's thyroiditis, 7 patients with typical subacute thyroiditis and 2 patients with the thyrotoxic phase of autoimmune thyroiditis. Both patients with Graves' disease and Hashimoto's thyroiditis had increased percentages of HLA-DR+ T (Ia+ CD3+) cells as well as HLA-DR+ helper-inducer T (Ia+ CD4+) cells, which seemed to be independent of treatments. The percentage of HLA-DR+ suppressor-cytotoxic T (Ia+ CD8+) cells was increased in euthyroid or hypothyroid patients with Graves' disease following treatment, but was normal in hyperthyroid patients. The percentages of Ia+ CD4+ cells and Ia+ CD8+ were also increased in patients with thyroiditis, whereas these abnormal values normalized in the remission phase. These findings suggest that an increase in Ia+ CD4+ cells characteristically occurs during immune system activation in patients with hyperthyroid Graves' disease, Hashimoto's thyroiditis and the thyrotoxic phase of subacute thyroiditis, whereas the activated CD8+ cells in Graves' disease are induced by antithyroidal therapy.

    Autoimmune diseases have been little studied in gay men and lesbians. We followed 4.4 million Danes, including 9,615 same-sex married (SSM) persons, for 47 autoimmune diseases in the National Patient Registry between 1989 and 2008. Poisson regression analyses provided first hospitalization rate ratios (RRs) comparing rates between SSM individuals and persons in other marital status categories. SSM individuals experienced no unusual overall risk of autoimmune diseases. However, the risk of autoimmune thyroid dysfunction was increased, notably Hashimoto's thyroiditis (women(SSM), RR = 2.92; 95% confidence interval (CI) 1.74-4.55) and Graves' disease (men(SSM), RR = 1.88; 95% CI 1.08-3.01). There was also an excess of primary biliary cirrhosis (women(SSM), RR = 4.09; 95% CI 1.01-10.7), and of psoriasis (men(SSM), RR = 2.48; 95% CI 1.77-3.36), rheumatic fever (men(SSM), RR = 7.55; 95% CI 1.87-19.8), myasthenia gravis (men(SSM), RR = 5.51; 95% CI 1.36-14.4), localized scleroderma (men(SSM), RR = 7.16; 95% CI 1.18-22.6) and pemphigoid (men(SSM), RR = 6.56; 95% CI 1.08-20.6), while Dupuytren's contracture was reduced (men(SSM), RR = 0.64; 95% CI 0.39-0.99). The excess of psoriasis was restricted to same-sex married men with HIV/AIDS (men(SSM), RR = 10.5; 95% CI 6.44-15.9), whereas Graves' disease occurred in excess only among same-sex married men without HIV/AIDS (men(SSM), RR = 1.99; 95% CI 1.12-3.22). Lesbians and immunologically competent gay men in same-sex marriage face no unusual overall risk of autoimmune diseases. However, the observed increased risk of thyroid dysfunction in these lesbians and gay men deserves further study. PMID:24306355

    Full Text Available Objectives: Assessment of autoimmune cause hypothyroidism and dyslipidemia involvement in the apparition of major vascular complications. Methods: A total of 152 patients were investigated appreciating in comparison to a healthy control lot the hormone serum level, the presence of antimicrosomal thyroid antibodies and the serum levels of lipids. Atherogenic index and coronarian risk were calculated and correlated with the incidence of coronarian and cerebral vascular accidents. Results: Among the patients with goiter it was noted a high incidence of a subclinical hypothyroidism (31,58%. Thyroid autoimmunity was involved in 94,4% of the patients with clinical hypothyroidism, in 93,7 % with subclinical hypothyroidism and 100% in the patients with thyrotoxicosis. Low serum level of HDL-cholesterol was identified in 66,6% of patients with clinical hypothyroidism and 64,5% patients with subclinical hypothyroidism. The assessment of atherogenic index and coronarian risk was significantly higher (p<0,01 in patients with hypothyroidism in comparison to healthy control subjects. The incidence of vascular accidents was significantly higher (p<0,01 among the hypothyroid patients ( 19,7%/ 10,8%, of masculine gender (12,7% where the main cause of hypothyroidism was autoimmunity. Conclusions: The atherogenic index and coronarian risk were higher in patients with hypothyroidism associated to thyroid autoimmunity resulting in an increased probability in producing vascular accidents

    AIM: To investigate the prevalence of coeliac disease in a series of Turkish patients with autoimmune thyroiditis.METHODS: Sera from 136 consecutive patients with newly diagnosed autoimmune thyroiditis and 119 healthy blood donors were tested for IgA tissue transglutaminase antibody with enzyme-linked immunosorbent assay. Endoscopic mucosal biopsy from the second part of duodenum was performed in patients with positive antibody test.RESULTS: Eight patients (5.9%) and one control subject (0.8%) were positive for IgA tissue transglutaminase antibody (OR: 7.38, 95% CI: 0.91-59.85, P = 0.04). Six patients and one control agreed to take biopsies. Histopathological examination revealed changes classified as Marsh ma in one, Marsh n in one, Marsh I in two, and Marsh 0 in two patients with autoimmune throiditis, and Marsh I in one blood donor.CONCLUSION: Turkish patients with autoimmune thyroiditis have an increased risk of coeliac disease and serological screening may be useful for early detection of coeliac disease in these patients. Our findings need to be confirmed in a larger series of patients.

    Full Text Available Background: Steroid replacement without thyroxine supplementation normalizes thyroid function test (TFT in some but not all Addison's disease patients with primary hypothyroidism. Both autoimmune and nonautoimmune mechanisms contribute to this improvement in TFT. However, the documentation of the change in thyroid autoimmunity after cortisol replacement is very limited in the literature. The aim of this study was to determine the effect of steroid replacement on TFT and anti-thyroid peroxidase antibody (anti-TPO-Ab titer in Addison's disease with primary hypothyroidism. Materials and Methods: This observational study was conducted in a tertiary care center in South India. Six Addison's disease patients with primary hypothyroidism, who were only on steroid replacement, were included in the study. Low serum cortisol (22 pmol/L and/or hyperpigmentation of skin/mucous membranes was considered as the diagnostic criteria for Addison's disease. Primary hypothyroidism (both overt and subclinical was defined as high thyroid stimulating hormone (TSH with/without low free thyroxine (fT4. TFT and anti-TPO-Ab were performed before and after steroid replacement in all of them. Results: Poststeroid replacement, there was a normalization of TSH in all but one subjects. In overt hypothyroidism patients, fT4 also normalized. The improvement in TFT was not associated with decreasing titer of the anti-TPO-Ab in all six patients. However, there was a significant difference in TSH after steroid replacement compared to the baseline status. Conclusions: The concept of normalization of primary hypothyroidism with cortisol replacement in patients with Addison's disease should be recognized to avoid iatrogenic thyrotoxicosis caused by thyroxine replacement. Both autoimmune and nonautoimmune mechanisms contribute to these alterations.

    Background Previous studies showed that the role of Fas ligand (FasL) is not consistent in the pathogenesis of autoimmune thyroiditis. This study was designed to investigate the effects of FasL on the pathogenesis of experimental autoimmune thyroiditis (EAT) using CMV-human FasL (hFasL) transgenic mice. Methods Transgenic mice ubiquitously expressing hFasL were used as an animal model of EAT by injection of porcine thyroglobulin (pTg). Expression of hFasL was detected by RT-PCR and Western blot. The activity of hFasL transgenic thyrocytes killing Jurket cells was determined. CMV-hFasL transgenic mice and wild type (WT) mice were immunized with pTg and killed 28 days later to evaluate the lymphocytic infiltration of their thyroids. The number of CD4+ and CD8+ lymphocytes from the spleen was detected using FACS. The serum interferon-γ (IFN-γ) concentration was measured by ELISA. Results hFasL expression in the thyroid of CMV-hFasL transgenic mice was confirmed. After co-incubation of Jurket thymocytes with thyroid tissues of CMV-hFasL transgenic mice, the percentage of apoptotic cells in the CMV-hFasL transgenic thyroid group was significantly higher than that of the control WT thyroid group [(23.4±4.3)% vs (6.6±2.5)%, P<0.01]. On day 28 after immunization with pTg, the infiltration index of lymphocytes in thyroids of the CMV-hFasL transgenic mice was significantly lower than that of the WT mice [(1.0±0.5) vs (2.1±0.7), P<0.001]. Moreover, the number of CD4+ and CD8+ lymphocytes of the spleen and serum IFN-γ concentration were significantly decreased in the CMV-hFasL transgenic mice. Conclusions FasL plays an important role in the pathogenesis of autoimmune thyroiditis. Transgenic mice ubiquitously expressing hFasL may strongly inhibit lymphocytic infiltration of the thyroid of EAT and ameliorate the course of this disease.

  6. A study of autoimmune thyroid disorder in atomic bomb survivors in Hiroshima, (2)

    International Nuclear Information System (INIS)

    To elucidate sequential changes of thyroid function in persons seropositive for anti-thyroid antibodies, thyrotropin releasing hormone (TRH) test was performed in 31 patients with asymptomatic autoimmune thyroiditis (AAT), 13 patients with struma (S), and 28 normal subjects. On the basis of basal TSH values, 26 of the AAT patients were classified as grade I, 4 as grade II, and 2 as grade III; and 8 of the S patients as grade I, 4 as grade II, and one as grade III. One patient with grade I AAT developed subclinical hypothyroidism (SHT). All grade III AAT and S patients were considered to have SHT. S patients were more likely than AAT patients to develop SHT. Regarding serum levels of total T4, total T3, total cholesterol, triglyceride, and lactic dehydrogenase, there was no significant correlation between grade I group and grade II + III group. Although the basal TSH value may be a somewhat important indicator for predicting thyroid function, abnormal basal TSH value returned to normal several years later even in the case of patients with increased value. There was no evidence that autoimmune thyroid disorder is frequent in A-bomb survivors exposed within 2,000 m from ground zero. (Namekawa, K.)

    Full Text Available In celiac disease (CD, for its multifactorial nature, the target organs are not limited to the gut, but include thyroid, liver, skin and reproductive and nervous systems. Between the extraintestinal symptoms associated with CD, autoimmune thyroid diseases (AITDs are more evident, underlining as CD-related autoimmune alterations can be modulated not only by gluten but also by various concurrent endogenous (genetic affinity, over-expression of cytokines and exogenous (environment, nutritional deficiency factors. In their pathogenesis a central role for over-expression of interleukin-15 (IL-15 is shown, by inhibiting apoptosis, leading to the perpetuation of inflammation and tissue destruction. Thyroid is particularly sensitive to selenium deficiency because selenoproteins are significant in biosynthesis and activity of thyroid hormones; besides, some selenoproteins as glutathione peroxidase are involved in inhibiting apoptosis. Thus, selenium malabsorption in CD can be thought as a key factor directly leading to thyroid and intestinal damage. Considering the complexity of this interaction and on the basis of available evidence, the aim of this review is to assess as preventive and therapeutic target the role of IL-15 and selenium in the pathogeneses of both CD and AITD.

  8. 99mTc-sestamibi thyroid uptake in euthyroid individuals and in patients with autoimmune thyroid disease

    International Nuclear Information System (INIS)

    We investigated the biokinetics of 99mTc-sestamibi in the thyroid of euthyroid volunteers (EVs) and in patients with autoimmune thyroid diseases and determined the best time interval between 99mTc-sestamibi injection and calculation of uptake. Forty EVs, 30 patients with Graves' disease (GD), 15 patients with atrophic Hashimoto's thyroiditis (AHT) and 15 patients with hypertrophic Hashimoto's thyroiditis (HHT) underwent 99mTc-sestamibi thyroid scintigraphy. Dynamic images were acquired for 20 min, and static images were obtained 20 min, 60 min and 120 min post injection. Five-, 20-, 60- and 120-min uptake, time to maximal uptake (Tmax) and T1/2 of tracer clearance were calculated. Thyroid hormones and antibodies were measured. 99mTc-pertechnetate uptake was investigated in GD patients. Tmax was approximately 5 min in all four groups. The mean T1/2 value for EVs was similar to the GD value and lower than the HHT and AHT values. The mean (±SD) 5-min uptake was 0.13% (±0.05%) for EVs. The 5-min uptake in GD was higher than that in EVs(P99mTc-pertechnetate uptake (r=0.68). Uptake in HHT was higher than that in AHT (P=0.0003) and EVs (P=0.002). Uptake in AHT was lower than uptake in EVs (P=0.0001). Five minutes is the optimal time interval between 99mTc-sestamibi injection and calculation of thyroid uptake. Five-minute uptake differentiates euthyroid individuals from GD patients. There is a high correlation between 99mTc-sestamibi and 99mTc-pertechnetate uptake in GD. The reduced 99mTc-sestamibi uptake in AHT patients is probably due to glandular destruction and fibrosis. Inflammatory infiltrate and high mitochondrial density in thyrocytes possibly explain the increased uptake in GD and HHT. (orig.)

  9. Thyrotropin - Binding Inhibiting Immunoglobulin (TBII) in Patients with Autoimmune Thyroid Diseases

    International Nuclear Information System (INIS)

    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.

    Full Text Available Abstract We report on a case of autoimmune thyroiditis in a 6-month-old patient with cortico-resistant nephrotic syndrome. Normal serum levels of thyroid hormons and thyroid-stimulating hormone were detected with high titers of circulant antithyroid antibodies and a dysomogeneous ultrasound appearance of the gland, typical of autoimmune thyroiditis. The research of maternal thyroid antibodies was negative. This is the first case of autoimmune thyroiditis found in such a young patient with pre-existing nephrotic syndrome ever described in literature. This association is random because nephrotic syndrome does not have an autoimmune pathogenesis and the genes involved in autoimmune thyroiditis are not related to those of nephrotic syndrome.

    Full Text Available Patients with Turner’s syndrome (TS are at an increased risk of developing autoimmune thyroid disease (ATD. The aim of this study was to determine the frequency of anti-thyroid peroxidase (anti-Tpo antibodies and ATD in children and adolescent girls with TS. It also assessed the influence of karyotype on the development of thyroid disease. Sixty eight patients with TS were compared with 68 age matched healthy unrelated girls in this study. They were screened for anti-Tpo antibodies, free T4 and TSH levels. Sign and symptoms of hypothyroidism and hyperthyroidism and the presence of goiter were also investigated. Anti-Tpo antibodies were found in 18 (26.4% TS patients and 1 (1.4% patient in the control group (P < 0.001, evenly distributed between the karyotypes 45X, 46X, isoXq and mosaicism. Out of 68 TS patients, 8 (11.7% had visible goiter. Subclinical hypothyroidism and hypothyroidism both occurred in 2 patients (5.9%. These patients were characterized by higher levels of anti-Tpo antibodies. Visible goiter was found in 3 (4.4% subjects of the control group, but all of them were euthyroid. We found that younger patients were more likely to be anti-Tpo negative (P < 0.001. Our data demonstrated a high frequency of ATD in a representative sample of Iranian girls with TS which is in accordance with previous observations. Regular follow up assessment of thyroid autoantibodies and thyroid function in patients with TS is recommended for timely diagnosis of thyroid dysfunction and treatment.

    Full Text Available Thyroid autoimmunity (TAI, which is defined as the presence of autoantibodies against thyroid peroxidase (TPO and/or thyroglobulin (TG, is related to repeated implantation failure (RIF. It is reported that TAI was involved in reproductive failure not only through leading thyroid function abnormality, but it can also be accompanied with immune imbalance. Therefore, this study was designed to investigate the association of thyroid function, immune status and TAI in women with RIF. Blood samples were drawn from 72 women with RIF to evaluate the prevalence of TAI, the thyroid function, the absolute numbers and percentages of lymphocytes. The prevalence of thyroid function abnormality in RIF women with TAI was not significantly different from that in RIF women without TAI (c2 = 0.484, p > 0.05. The absolute number and percentage of T cells, T helper (Th cells, B cells and natural killer (NK cells were not significantly different in RIF women with TAI compared to those without TAI (all p > 0.05. The percentage of T cytotoxicity (Tc cells was significantly decreased in RIF women with TAI compared to those without TAI (p < 0.05. Meanwhile, Th/Tc ratio was significantly increased (p < 0.05. These results indicated that the decreased Tc percentage and increased Th/Tc ratio may be another influential factor of adverse pregnancy outcomes in RIF women with TAI.

    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.

    Full Text Available Purpose: Many reports have indicated an association between thyroid dieases and primary Sjögren’s syndrome (pSS. The aim of our study was to evaluate the outcomes of the tests used for dry eye diagnosis and salivary gland involvement in patients with autoimmune thyroiditis. Methods: Forty-two patients (group 1 with autoimmune thyroid disease and 30 controls (group 2 were selected. Tear film break up time, Schirmer I test, Schirmer II test, ocular staining with 1% rose Bengal and salivary gland cintilography were performed in both groups. Results: Regarding the ocular surface damage observed by Rose Bengal test there was no difference between groups (p=0.77. For tear film break up time the groups did not differ statistically (p=0.46. There was no statistical difference between groups 1 and control in scintigraphy of the salivary gland (p=0.99. A statistical difference between the patients with thyroid disease and the control group was seem only in the Schirmer II test (p=0.0009. Conclusions: No patients fulfilled all criteria for Sjögren’s syndrome. It is possible that it could be underestimated.

    AIM: To investigate the effect of interleukin-10 (IL-10) gene on experimental autoimmune thyroiditis mice.METHODS: Mice were immunized to induce autoimmune thyroiditis with porcine thyroglobulin (pTg), and thyroids of mice were injected with IL-10 DNA. On d 28 after immunization with pTg, mRNA expression of IL-10 inthyroid glands was detected and thyroid specimens were histopathological studied. RESULTS: The mRNA expression of IL-10 was detected in thyroid glands on d 7 and 14 after injection of IL-10 plasmid DNA or on COS-7 cells48 h after IL-10 plasmid DNA transfection. In addition, hlL-10 levels in culture media significantly increased 48 hand 72 h after IL-10 plasmid DNA transfection. Infiltration index of lymphocytes (1.1±0.4) in thyroids ofIL-10-treated mice was significantly lower than that of pcDNA3-null-treated mice (2.2±0.5) (P<0.01). Comparedwith pcDNA3-null control mice, IL-10-treated mice had lower levels of serum IFN-γ(P<0.01). CONCLUSION:The direct injection of DNA expression vectors encoding IL-10 into thyroid significantly inhibited development oflymphocytic infiltration of thyroid of autoimmune th,yroiditis mice, and alleviated the progression of this disease.

    Full Text Available Thyroid carcinoma is rare comprising 1% of all malignancies and commonly presents as a neck lump. Papillary thyroid carcinoma unlike follicular thyroid carcinoma tends not to metastasise to distant sites.We present a case of papillary thyroid carcinoma presenting as a solitary asymptomatic pelvic bone metastases and highlight current management of bone metastases. A 59-year old female was found on abdominal computerised tomography to have an incidental finding of a 4.5 cm soft tissue mass in the right iliac bone. Biopsy of the lesion confirmed metastatic thyroid carcinoma. There was no history of a neck lump, head and neck examination was normal. Further imaging confirmed focal activity in the right lobe of the thyroid. A total thyroidectomy and level VI neck dissection was performed and histology confirmed follicular variant of papillary carcinoma.Early detection of bone metastases have been shown to improve prognosis and thyroid carcinoma should be considered as a potential primary malignancy.

    Hashimoto's thyroiditis has been shown to be associated with the HLA-specificities DR4 and DR5. Since former association studies yielded variable results, we used novel molecular typing methods to assess predisposing immunogenetic factors. Gene analysis of the HLA-DR-DQ and tumor necrosis factor region was performed in a group of Hashimoto's thyroiditis patients and randomly chosen controls using standards and nomenclature of the 10th International Histocompatibility Workshop. Genomic DNA of patients and controls was analyzed using a cDNA probe of the DQB1 gene. The resulting restriction fragment patterns allowed the determination of newly defined DQw-types 1-9. We find the strongest relative risk conferred by DQw7 (RR = 4.7), that is observed in 36 of 64 patients (56%) and only 21 of 98 controls (21%) (P corr less than 0.002). Comparison of DNA sequence variation in the DQB1 gene, that is found predominantly in Hashimoto's thyroiditis patients, indicates that codons 45 and 57 are critical features in DQw7 which distinguish it from other DQw specificities. The adjacent DQA1 genes also display a significant association with Hashimoto's thyroiditis (DQA1*0201/*0301 heterozygotes were found in 37% of patients and 15% controls, P less than 0.03). No significant association could be found with polymorphisms of the tumor necrosis factor gene. These results provide a new basis for the concept of genetic susceptibility in Hashimoto's thyroiditis and will help to elucidate the underlying autoimmune mechanisms that lead to disease at the functional level.

    International Nuclear Information System (INIS)

    The purpose of this study is the evaluation of the TCTUs in the differentiation between AIT and GD in patients with hyperthyroidism. Methods: We determined the TCTUs in 59 patients with untreated hyperthyroid GD and in 51 patients with AIT who had subclinical or manifest hyperthyroidism without medication. Patients with GD were characterized by the presence of hyperthyroidism, decreased echogenicity of the thyroid, elevation of TSH-receptor autoantibodies (TRAb). AIT was defined by a decreased echogenicity of the thyroid, absence of elevated TSH-receptor autoantibodies (TRAb), autoantibodies against the thyroid peroxidase (anti-TPO) and spontaneous remission or development of subclinical hypothyroidism within 3 months. Results: Thyroid volumes of patients with AIT were significantly lower than those of patients with GD (p99mTcO4- offered rapid and reliable differentiation between hyperthyroid GD and AIT. (orig.)

    Fish consumption or supplementation with omega-3 fatty acids was reported to cure and/or prevent autoimmune and nonautoimmune disorders. Serum positivity for thyroid autoantibodies is a predictive marker of postpartum thyroiditis and postpartum depression. We hypothesized that stable consumption of the omega-3-rich oily fish was associated with a more favorable profile of serum thyroid antibodies throughout pregnancy and early postpartum compared with stable consumption of swordfish, a predator that concentrates pollutants. We prospectively measured serum thyroglobulin antibodies and thyroperoxidase antibodies in pregnancy (first, second trimesters) and postpartum (day 4), in 236 thyroid disease-free, nonsmoker Caucasian women with stable dietary habits. We did not measure thyroid autoantibodies prior to pregnancy. Women were divided into groups A (n = 48; swordfish), B (n = 52; oily fish), C (n = 68; swordfish + other fish, not necessarily oily fish), and D (n = 68; fish other than swordfish and oily fish). Major endpoints were positivity rates and serum concentrations of the two autoantibodies. We resorted to previous studies for the estimated content of fatty acids and microelements in the consumed fish. Positivity rates and serum concentrations of both antibodies were the greatest in group A and the lowest in group B (P postpartum problems, our data suggest a dietary prophylaxis of such problems.

  4. Spontaneous autoimmune thyroiditis in obese strain chickens: a genetic analysis of target organ abnormalities

    International Nuclear Information System (INIS)

    In this study the authors investigated the genetic background of primary abnormalities found in the thyroid gland of Obese strain (OS) chickens with spontaneous autoimmune thyroiditis (SAT), i.e., susceptibility to passively transferred antibodies to thyroglobulin (TgAb) and incomplete suppression of iodine uptake by thyroxine (T4). Several crosses between the B15/B15 subline of OS chickens and the inbred CB line (B12/B12) were done and the progeny was analyzed for thyroiditis after injection of OS serum containing high titers of TgAb. It was found that passive transfer of TgAb increased the lymphoid infiltration in the thyroids of OS chickens, but had no effect on CB birds. A genetic analysis of backcrosses revealed that this trait is, in the case of simple Mendelian inheritance, encoded by at least three recessive genes. The thyroidal 131I uptake of these crosses under T4 was also determined and they found that this trait is most probably encoded by only one recessive gene

    The authors investigated whether the associations between HLA alleles of patients with autoimmune hypothyroidism varied according to the presence or absence of TSH receptor-blocking antibody (TRBab). They analyzed the HLA-A, -B, -C, and -DR antigens by serotyping and the DQA1 and DQB1 genes using both enzymatic DNA amplification and sequence-specific oligonucleotide hybridizations. The patient population consisted of 47 Korean patients with atrophic autoimmune thyroiditis and 62 patients with goitrous autoimmune thyroiditis. The antigen frequency of HLA-DR8 was significantly increased in 23 atrophic autoimmune thyroiditis patients that were positive for TSH binding inhibitor immunoglobulin (TBII) compared to 136 controls [52% vs. 16%; x[sup 2] = 13.1; Pc (corrected P value) = 0.003]. This relative risk was 5.7; the etiological fraction was 0.43. HLA-DQB1*0302 was also increased in patients with TBII-positive atrophic autoimmune thyroiditis (24% vs. 7%; x[sup 2] = 11.2; Pc = 0.012; relative risk = 4.4; etiological fraction = 0.19). No specific DR antigens or DQB1 alleles were increased in either TBII-negative atrophic autoimmune thyroidities or goitrous autoimmune thyroiditis. A significant decrease in the frequency of HLA-DR6 antigen was observed in both TBII-positive atrophic antoimmune thyroiditis (0% vs. 32%; x[sup 2] = 8.4; Pc = 0.03) and goitrous autoimmune thyroiditis (0% vs. 32%; x[sup 2] = 23.2; Pc < 0.001) patients. The frequency of the HLC-Cwl antigen was significantly increased in all patient groups. The authors conclude that TRBab-positive atrophic autoimmune thyroiditis is immunogenetically different from both goitrous autoimmune thyroiditis and TRBab-negative atrophic autoimmune thyroiditis. It is possible that HLA-DR8 and/or DQB1*0302 may be related to the susceptibility genes involved in the production of TRBab in Koreans. 32 refs., 5 tabs.

    Full Text Available Objective: To study pregnancy outcomes in relation to thyroid peroxidase antibody (TPOAb status with optimum thyroxine replacement for subclinical hypothyroidism. Materials and Methods: Ninety-eight women with subclinical hypothyroidism were followed up until the end of their pregnancy. TPO antibody status was performed for 59 women (positive 20, negative 39. Levothyroxine was supplemented to maintain TSH between 0.3-3 mIU/l in all patients, irrespective of TPOAb status. Pregnancy outcomes were noted as pregnancy-induced hypertension (PIH, antepartum or postpartum hemorrhage, preterm delivery, and spontaneous abortion. Outcomes were compared between 3 groups as per TPO antibody status (positive, negative, and undetermined, which were matched for age and gestational period. Results: Thyroid autoimmunity was noted in 34% of women screened for TPO antibody. A total of 11 adverse pregnancy outcomes were recorded (4 spontaneous abortions, 4 preterm deliveries, 3 PIH with no significant difference between the groups. Conclusion: Adverse pregnancy outcomes were not different in the 3 groups with adequate thyroxine replacement for pregnant women with subclinical hypothyroidism targeting TSH in euthyroid range, irrespective of thyroid autoimmunity status.

    Full Text Available Abstract Background Higher serological prevalence rates of helicobacter pylori (H. pylori infection have been reported in patients with type 1 diabetes (T1DM and autoimmune thyroiditis (AT. Patients with T1DM are at increased risk for developing other autoimmune diseases, most commonly AT. It is unknown whether H. pylori infection could explain the high prevalence of thyroid autoantibodies and AT in T1DM. The aim of the current study was to evaluate anti-thyroid peroxidase (anti-TPO and anti-thyroglobulin (anti-Tg autoantibodies in correlation with anti-H. pylori IgG and IgA in young patients with T1DM. Methods Anti-H. Pylori IgG, IgA, anti-TPO and anti-Tg antibodies titers were measured in 162 euthyroid patients with T1DM and 80 healthy controls matched for age, sex and socioeconomic status. Results Seroprevalence of H. pylori was significantly higher in patients with T1DM than in healthy controls; 79% vs. 51.2%, p Conclusion our results support the idea of a connection between H. pylori infection and the occurrence of anti-TPO, anti-Tg autoantibodies and AT in young patients with T1DM. So, H. pylori infection could be considered as an environmental trigger for development of AT in T1DM. Young patients with T1DM should be screened for H. pylori infection.

    Full Text Available We herewith describe a patient with acute confusion, expressive aphasia and generalized seizures. A through workup excluded most causes of encephalopathy. 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.

  10. The influence of cyclosporin A on experimental autoimmune thyroid disease in the rat

    International Nuclear Information System (INIS)

    Female PVG/c rats, thymectomised on weaning and given 4 courses of whole body irradiation to a total dose of 1000 rads, developed experimental autoimmune thyroid disease (EAITD) as assessed by histological evidence of thyroiditis and circulating levels of antithyroglobulin antibodies. Hypothyroidism resulted. Induction of the disease was associated with a highly significant fall in T lymphocyte numbers. Eight weeks after their last dose of irradiation the animals commenced treatment with cyclosporin A (10 mg/kg rat/day, intragastrically) and were treated for varying time intervals thereafter. The reversal of the T lymphocyte helper: suppressor ratio on cyclosporin A therapy was associated with a significant improvement in the disease process. The alterations in the T cell subsets and in the disease lasted only as long as the drug was administered and thereafter reverted towards that seen in the control groups of animals receiving no treatment

    To elucidate the hormonal change and alteration in cytokine expression in peripheral blood mononuclear cells (PBMC) during the early stage of autoimmune thyroiditis, we have developed a canine model of this disease, in which normal dogs were immunized with bovine thyroglobulin (Tg) and/or canine thyroid extract. Serum samples were collected weekly, anti-canine Tg antibody was measured by enzyme-linked immunosorbent assay (ELISA) and thyroid stimulating hormone (TSH) and total T4 levels by radioimmunoassay. We also assayed T lymphocyte proliferation in response to Tg, as well as measuring cytokine mRNA by semiquantitative reverse transcription-polymerase chain reaction (RT-PCR). All six dogs immunized with bovine Tg had both canine Tg autoantibody and anti-T4 antibody. When the sample from the highest TgAA titre time-point was compared with baseline the expression of mRNA encoding the Th1-type cytokine such as interferon (IFN)-gamma, interleukin (IL)-18 and IL-15 was increased during the development of autoimmune thyroiditis. Expression of the Th2-type cytokine, IL-6 showed minimal change and IL-4 expression was not detected in any of the samples. Expression of the T suppressive cytokine, IL-10 and transforming growth factor (TGF)-beta was increased in the presence of antigen stimulation. These findings suggest that, although autoimmune thyroiditis is an organ-specific autoimmune disease, systemic cytokine mRNA expression is also changed. PMID:16968404

    Full Text Available Autoimmune polyglandular syndromes are characterized by the association of two or more autoimmune diseases. They are classified into two major subtypes, each having its own characteristics. The autoimmune polyglandular syndrome type 2 is defined by the presence of at least two of the following diseases: Addison’s disease, type 1 diabetes mellitus and thyroid autoimmune disease. Other autoimmune diseases belonging to the autoimmune polyglandular syndrome type 2 are: primary hypogonadism, myasthenia gravis, celiac disease, pernicious anemia, alopecia, vitiligo. We are going to present the case of a patient, aged 40, with diabetes mellitus (probably latent autoimmune diabetes of the adult, chronic autoimmune thyroiditis and celiac disease.

  13. Virtual touch tissue quantification (VTQ) in the diagnosis of thyroid nodules with coexistent chronic autoimmune Hashimoto's thyroiditis: A preliminary study

    International Nuclear Information System (INIS)

    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

  15. Studies on thyroglobulin-specific suppressor T cell function in autoimmune thyroid disease

    International Nuclear Information System (INIS)

    T cell regulation of the generation of thyroglobulin plaque-forming cells (Tg PFC) and protein A plaque-forming cells (Prot A PFC) was investigated using lymphocytes from patients with autoimmune thyroid disease. T and B cell mixed cultures (T-B MC) were carried out without mitogenic or antigenic stimulation to identify physiological T cell effects in the system. Tg PFC were found in 8 (44%) of 18 patients who had high titers of thyroglobulin antibody in their sera. Tg-specific and nonspecific immunoregulation by T cells from patients and normal subjects was studied using B cells from these eight patients in the T-B MC system. Remarkably lower values of Tg PFC induction compared to Prot A PFC induction were found after T cell addition. Normal T cells inhibited Tg PFC induction, but patient T cells did not, while the same extent of helper effects were found on Prot A PFC induction by the addition of patient and normal T cells. Irradiation (1500 rads) of T cells from patients and normal subjects significantly enhanced both Tg PFC and Prot A PFC induction. Thus, Tg-specific suppressor T cells are present in all normal subjects as part of the radiosensitive suppressor T cell subset. The increase in Tg-PFC caused by irradiation-induced inhibition of Tg-specific suppressor T cell function was significantly greater in normal subjects than in patients. Histamine type 2 receptor-bearing T cells inhibited Prot A PFC induction, but not Tg PFC induction, in the autologous T-B MC system. No Tg PFC were induced from normal B cells in any combination with untreated T cells, irradiated T cells, or histamine type 2 receptor-negative T cells from patients or normal subjects

    @@ Papillary thyroid carcinoma (PTC) is the most common type of well-differentiated thyroid cancer and is considered to be a relatively indolent tumor in which distant metastasis and death are rare.1 The metastasis of PTC is usually to regional lymph nodes, especially the cervical and mediastinal nodes. Metastases to the brain are rare, and constitute 0.1%-5.0% of distant metastases of papillary carcinoma.2 Skull metastasis is uncommon,and is found in 2.5%-5.8% of cases of thyroid cancer.3 Skull base metastasis of PTC is extremely rare, with only eight reported cases in the literature involving the clivus,cavernous sinus, sella turcica, and the petrous apex and ridge.4 A metastatic lesion can arise from histologically benign and silent thyroid neoplasms,5 and differential diagnosis between ectopic and metastatic thyroid cancer can be difficult,6 therefore, the management of thyroid cancer is controversial after removal of metastatic disease.Here we reported a case of papillary thyroid microcarcinoma (PTMC) that was manifested as a solitary clivus metastasis and discussed the diagnostic and therapeutic management strategies. The 73-year-old patient presented with visual impairment in the right eye,and epistaxis. The patient subsequently underwent complete total thyroidectomy after a diagnosis of papillary microcarcinoma. This finding emphasizes that clinically significant metastases can arise from thyroid papillary microcarcinoma. Total thyroidectomy and careful review of the histology are necessary to prevent delay in proper diagnosis.

  17. A study of autoimmune thyroid disorder in atomic bomb survivors in Hiroshima, (3)

    International Nuclear Information System (INIS)

    To determine sequential changes in thyroid function after developing asymptomatic autoimmune thyroiditis (AAT) in A-bomb survivors, initial findings of thyrotropin-releasing hormone (TRH) test were compared with those 2 years after developing AAT (n=22) and struma (S) (n=12). According to Bastenie's classification, AAT or S patients were clinically staged into three grades. Among 17 patients who had initially had AAT I, one each developed Grade II and III two years later. Initial Grade II turned to Grade I at 2 years in 2 of 4 AAT patients and in 2 of 3 S patients. In both the AAT and S groups, Grade III remained unchanged two years later. There was no significant change in basal or peak thyroid stimulating hormone level between patients with Grade I and those with Grade II or III in both the AAT and S groups. There were no sequential changes in total and free T4, total and free T3, total cholesterol, triglyceride, and lactic dehydrogenase. The TRH test is unlikely to reflect the development of hypothyroidism. (N.K.)

    Background. Studies in several ethnic groups reported high incidence of elevated levels of immunoglobulin E (IgE) in patients with autoimmune thyroid diseases (ATD), especially in patients with Graves' disease. Objective. To study association between serum levels of IgE and thyroid stimulating hormone receptor antibodies (TRAb) in Albanian patients with ATD. Material and Methods. Study was performed in 40 patients with Graves' disease, 15 patients with Hashimoto's thyroiditis, and 14 subjects in the control group. The IgE levels were measured by immunoradiometric assay, whereas the TRAb levels were measured by radioreceptor assay. Results. In all groups of subjects the IgE levels were within reference values (<200 kIU/L). Significant difference in mean concentration of IgE was found between two groups of Graves' disease patients, and those with normal and elevated TRAb levels (22.57 versus 45.03, P < 0.05). Positive correlation was found between TRAb and IgE only in Graves' disease patients (r = 0.43, P = 0.006). Conclusion. In Albanian patients with ATD there is no elevation of IgE levels. This could be the result of low prevalence of allergic diseases in Albanian population determined by genetic and environmental factors. PMID:24959371

    Full Text Available Alpha interferon (αIFN therapy is known to induce thyroid autoimmunity in up to 40% of patients. The mechanism is unknown, but Th1 switching has been hypothesized. The aim of our study was to examine whether αIFN accelerated the development of thyroiditis in genetically susceptible mice. We took advantage of NOD-H2h4, a genetically susceptible animal model, which develops thyroiditis when fed a high iodine diet. Six to eight week old male NOD H2h4 mice were injected with mouse αIFN (200 units or with saline three times a week for 8 weeks. All mice drank iodinated water (0.15%. Mice were sacrificed after 8 weeks of injection. Their thyroids were examined for histology and blood was tested for antithyroglobulin antibody levels. T4 and glucose levels were also assessed. In the IFN-injected group, 6/13 (46.2% developed thyroiditis and/or thyroid antibodies while in the saline-injected group, only 4/13 (30.8% developed thyroiditis and/or thyroid antibodies (p=0.4. The grade of thyroiditis was not different amongst the two groups. None of the mice developed clinical thyroiditis or diabetes mellitus. Our results showed that αIFN treatment did not accelerate thyroiditis in this mouse model. This may imply that αIFN induces thyroiditis in a non-genetically dependent manner, and this would not be detected in a genetically susceptible mouse model if the effect were small. Alternatively, it is possible that αIFN did not induce thyroiditis in mice because, unlike in humans, in mice αIFN does not induce Th1 switching.

  20. Present trends in laboratory diagnosis of thyroid glands

    International Nuclear Information System (INIS)

    A brief survey is presented of the main in vitro methods presently used in the diagnosis of disorders of the thyroid gland. Next to the determination of total thyroxine, the determination of TSH (thyroid stimulating hormone) has come to the fore as a test used for verifying hypothyrosis and hyperthyrosis. Modern methods for the so-called direct determination of free thyroid hormones, primarily free thyroxine which in recent years aroused great hopes as a means of rapid and accurate assessment of the function of the gland also have their limitations and do not resolve controversial problems related to the accurate determination of total free thyroxine. The direct determination of concentrations of TBG (thyroxine-binding globulin) is a complement of thyroid function tests only in case of suspect abnormality of TBG concentration. The determination of thyroglobulin is considered to be useful in differentiated carcinoma of the thyroid gland as an indicator of relapse and the new early incidence of metastases in patients following surgery and isotope destruction of the thyroid gland and metastases. Next to radioisotope methods (radioimmunoassay and the radioimmunometric method) enzyme immunoassay methods are being used in in vitro diagnostics of the thyroid gland. (author). 1 tab., 20 refs

    Low 25(OH) vitamin D levels have been associated with several autoimmune diseases and recently with autoimmune thyroid disease (AITD). The aim of the study was to investigate the association of AITD with 25(OH) vitamin D levels in women with polycystic ovary syndrome (PCOS). Fifty women with PCOS were consecutively enrolled and underwent routine health checkups, which included measurements of 25(OH) vitamin D, anti-thyroid peroxidase (TPO-Ab), anti-thyreoglobulin (TG-Ab) antibodies, FT3, FT4, and TSH. Selecting 50 nmol/L as cut-off point, low 25(OH) vitamin D levels were detected in 23 of 50 patients (46 %). AITD was diagnosed when TPO-Ab levels exceeding 80 U/ml and/or TG-Ab levels exceeding 70 U/ml. AITD was detected in 12 of 50 patients (24 %). The levels of 25(OH) vitamin D were significantly lower in women with PCOS and AITD when compared with women with PCOS and without AITD (p = 0.02). In women with AITD no correlation was found between 25(OH) vitamin D and TG-Ab (r = 0.48; p = 0.16), TPO-Ab (r = 0.43; p = 0.21), TSH (r = 0.38; p = 0.27), FT3 (r = -0.40; p = 0.25) and FT4 levels (r = -0.54; p = 0.10). These findings suggest that low levels of 25(OH) vitamin D were significantly associated with AITD in women with PCOS. PMID:26433740

    2012-02-01

    Full Text Available Abstract Introduction Autopsy series have shown that metastasis to the thyroid gland has occurred in up to 24% of patients who have died of cancer. Neuroendocrine tumors may metastasize to thyroid gland. Case presentations Case 1 was a 17-year-old Turkish woman who was referred from our Endocrinology Department for a thyroidectomy for treatment of neuroendocrine tumor metastasis. She was treated with a bilateral total thyroidectomy. Histopathological examination results were consistent with a neuroendocrine tumor; neoplastic cells showed strong immunoreactivity to chromogranin A and synaptophysin, but the immunohistochemical profile was inconsistent with medullary thyroid carcinoma in that the tumor was negative for calcitonin, carcinoembryonic antigen, and thyroid transcription factor-1. Case 2 was a 54-year-old Turkish woman who presented with a 3-cm nodule on her right thyroid lobe. She had undergone surgery for a right lung mass four years previously. After a right pneumonectomy, thymectomy and lymph node dissection, a typical carcinoid tumor was diagnosed. Under ultrasonographic guidance, fine needle aspiration biopsy of her right thyroid pole nodule was performed and the biopsy was compatible with a neuroendocrine tumor metastasis. She was treated with a bilateral total thyroidectomy. Histopathological examination indicated three nodular lesions, 5 cm and 0.4 cm in diameter in her right lobe and 0.1 cm in diameter in her left lobe. The tumors were consistent with a neuroendocrine phenotype, showing strong immunoreactivity to chromogranin A and synaptophysin. Conclusion Thyroid nodules detected during follow-up of neuroendocrine tumor patients should be thoroughly investigated. A fine needle aspiration biopsy of the thyroid confirms the diagnosis in most cases and leads to appropriate management of those patients and may prevent unnecessary treatment approaches.

  4. The effects of female sex steroids on the development of autoimmune thyroiditis in thymectomized and irradiated rats

    International Nuclear Information System (INIS)

    Female PVG/c strain rats are more susceptible to induction of autoimmune thyroiditis initiated by thymectomy and irradiation (Tx-X) than similarly treated males. Pre-pubertal ovariectomy further augmented susceptibility. Administration of oestrogen or progesterone to groups of 4 weeks old ovariectomized Tx-X animals over a period of 15 weeks significantly altered induction of this condition. Oestrogen administered repeatedly at dose levels of 1 μg and 10 μg/100 g body weight resulted in partial suppression of thyroiditis with a corresponding change in the incidence of antibodies to thyroglobulin. Oestrogen administered by a single implantation had a suppressive effect on the development of autoimmunity in ovariectomized Tx-X females. Oestrogen given by either of these procedures also reduced the incidence of thyroiditis and autoantibody induction in orchidectomized male Tx-X rats. In contrast, repeated administration of progesterone at a dose of 250 mg and 1,500 μg/100 g body weight appeared to augment levels of autoimmunity. It is concluded that the differential susceptibility to the induction of autoimmunity by thymectomy and irradiation is the direct consequence of sex hormonal influences. The higher incidence of the disease in the female would appear to be determined by the balance between the activity of oestrogen and progesterone which would further appear to have antagonistic influences in this particular situation.

    Autoimmune hypophysitis (AH) - often referred to as lymphocytic hypophysitis - is a rare disease that affects the pituitary gland and causes inflammation. The disease enlarges the pituitary gland and the clinical presentations are lack of pituitary function and headaches. AH is mostly seen in women...... during pregnancy or postpartum, but also occurs in males and children. AH is often associated with other autoimmune diseases, most frequently with Hashimoto's thyroiditis. The symptoms are caused by enlargement of the pituitary gland and disturbances of the hormone function. Treatment is either...

  6. Clinical implications of a new TSH-receptor-antibody-assay (DYNOtest trademark TRAKhuman) in autoimmune thyroid diseases

    International Nuclear Information System (INIS)

    Aim: Conventional radioreceptor-antibody-assays (RAAs) fail in the detection of TSH-receptor antibodies (TRAKs) in 10-30% of patients with Graves' disease (GD). The aim of this study was the evaluation of the diagnostic and clinical impact of a new RRA (DYNOtest trademark TRAKhuman) which uses the human recombinant TSH-Receptor in the diagnosis of autoimmune thyroid disease. Methods: Sera from 142 consecutive patients (GD: n=50, autoimmune thyroiditis/AIT: n=92) and from 55 controls (31 patients without any thyroid disease and 14 with euthyroid goiter) were evaluated both with the DYNOtest trademark TRAKhuman-assay and a conventional RRA (TRAK-Assay trademark). Thyroid in vitro parameters and thyroid sonography were performed in all patients. Results: The DYNOtest trademark TRAK-assay was significantly superior to the conventional RRA in the diagnosis of GD (ptrademark as well as in the DYNOtest trademark TRAKhuman-Assay. Therefore the specifity of the DYNOtest trademark TRAKhuman was not inferior compared with the conventional assay. Conclusion: The DYNOtest trademark TRAK-assay is superior in the diagnostic work up of Graves' disease compared with a conventional TRAK-assay and offers an equal specifity. (orig.)

    2012-01-01

    All cases of familial thyrotoxicosis with absence of evidence of autoimmunity and all children with persistent isolated neonatal hyperthyroidism should be evaluated for familial non-autoimmune autosomal dominant hyperthyroidism (FNAH) or persistent sporadic non-autoimmune hyperthyroidism (PSNAH). First, all index patients should be analysed for the presence/absence of a thyroid-stimulating hormone (TSH) receptor (TSHR) germline mutation, and if they display a TSHR germline mutation, all other family members including asymptomatic and euthyroid family members should also be analysed. A functional characterization of all new TSHR mutations is necessary. Appropriate ablative therapy is recommended to avoid relapses of hyperthyroidism and its consequences, especially in children. Therefore, in children the diagnosis of FNAH or PSNAH needs to be established as early as possible in the presence of the clinical hallmarks of the disease. PMID:24783013

    The majority of dengue viral infections are asymptomatic, though symptoms may range from self-limiting febrile illness to life threatening hemorrhagic manifestations. As the burden of disease is dramatically rising in recent years, more patients with atypical presentations and rare complications are increasingly reported. Dengue virus may rarely involve different organ systems including CNS, liver, and heart. However, involvement of eye and thyroid is extremely rare. We present a case of 32-year old patient who presented with conjunctivitis and subacute thyroiditis and was found to have dengue viral infection as the cause of these conditions. PMID:27376214

    Full Text Available Few studies have been reported from the Kingdom of Saudi Arabia (SA to describe the clinical presentation and long term outcomes of subacute thyroiditis (SAT. Our aim was to review the demographic, anthropometric, clinical presentation, laboratory results, treatment, and disease outcome in Riyadh region and to compare those with results from different regions of the Kingdom and different parts of the world. We reviewed the medical files of patients who underwent thyroid uptake scan during an 8-year period in King Khalid University Hospital. Only 25 patients had confirmed diagnosis of thyroiditis. Age and gender distribution were similar to other studies. Most patients presented with palpitation, goiter, and weight change. Elevated thyroid hormones, suppressed thyroid-stimulating hormone, and elevated ESR were reported. Among those, 7 cases of SAT were recorded. β-Blockers were prescribed to 57% and nonsteroidal anti-inflammatory drugs to 29% of SAT. Long follow-up demonstrated that 85.7% of SAT cases recovered, while 14.3% developed permanent hypothyroidism. In conclusion, SAT is uncommon in the central region of SA. Compared to the western region, corticosteroid is not commonly prescribed, and permanent hypothyroidism is not uncommon. A nation-wide epidemiological study to explain these interprovincial differences is warranted.

    Autoimmune diseases occur due to faulty self-tolerance. Graves' disease (GD) and Hashimoto's thyroiditis (HT) are classic examples of organ-specific autoimmune diseases. GD is an auto-antibody-mediated disease where autoantibodies are produced against the thyroid stimulating hormone receptor (TSHR). HT is primarily a T-cell mediated disease, and whether B cells play a pathogenic role in the pathogenesis is still unclear. Both GD and HT are characterized by infiltration of the thyroid gland by self-reactive T cells and B cells. In the first paper of this thesis, the role of regulatory B cells (Bregs) and regulatory T cells (Tregs) were investigated in the context of GD and HT. First, we studied the role of the thyroid self-antigen, thyroglobulin (TG) in healthy donors. The self-antigen TG, but not the foreign recall antigen tetanus toxoid (TT), was able to induce interleukin 10 (IL-10) secretion by B cells and CD4+ T cells. These IL-10 producing B cells (B10 cells) from healthy donors were enriched with the CD5+ and CD24hi phenotype. In addition, TG was able to induce IL-6 production by B cells. In contrast, TT induced production of Th1-type pro-inflammatory cytokines including interferon-gamma (IFN-γ) and IL-2. In the second paper, the frequency and phenotype of B10 was investigated in healthy donors and patients with GD or HT.  The frequencies of B10 cells were similar in the three groups, irrespective of whether IL-10 was induced by a combination of phorbol 12-myristate 13-acetate (PMA) and ionomycin, by CpG oligodeoxynucletodies (ODN) 2006, or by TG. Several phenotypes have been associated with B10 cells such as CD5+, CD25+, TIM-1+, CD24hiCD38hi and CD27+CD43+. We found that larger proportions of B10 cells in patients with GD or HT were CD25+ and TIM-1+ than B10 cells in healthy donors. In healthy donors, B10 cells were CD24hiCD38-, whereas for HT patients these cells were primarily CD24intCD38int. For GD patients, we found lower proportions of B10 cells

  15. The Roles of the TSH Receptor Antibodies in Autoimmune Thyroid Diseases

    International Nuclear Information System (INIS)

    To evaluate the clinical and pathogenetic roles of TSH receptor antibodies in autoimmune thyroid diseases, TBII were measured by TSH-radioreceptor assay methods in 352 patients with Graves disease, 108 patients with other thyroid diseases and 69 normal persons. The normal range of TBII activity was less than 15%. The frequencies of detectable TBIl in 169 patients with untreated Graves disease, 31 patients with hyperthyroidism under treatment and 70 patients with euthyroidism under treatment were 92.4%, 87.1% and 54.3% respectively. However 12 (21.8%) out of 55 patients who have been in remission more than one year after discontinuation of antithyroid drugs treatment had detectable TBII activities in their sera. In 196 patients with untreated Graves disease, the frequency of TBII increased by increasing size of goiter and the frequency of proptosis was significantly high in patients whose TBII activities were more than 60%. TBll activities were roughly correlated with total T3,T4 and free T4, index but low γ2 value(less than 0.1). In 67 patients with Graves' disease who were positive TB1I before antithyroid drugs treatment, TBII activities began to decrease from the third months and it was converted to negative in 35.8% of patients at 12 months after treatment. There were no significant differences of the declining and disappearing rates of TBII activities between high dose and conventional dose groups. TBII activities were significantly increased initially (2-4 months) and then began to decrease from 5-9 months after 131I treatment. There were two groups, one whose TBII activities decreased gradually and the other did not change until 12 months after subtotal thyroidectomy. Although preoperative clinical and laboratory findings of both groups were not different, TBII activities of non-decreasing group were significantly higher than those of decreasing group(74.6+18.6% vs 39.2+15.2%; P(0.01). Thirty three(55.9%) out of 59 patients with Graves disease relapsed

    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.

    Thyroglobulin (Tg) represents one of the largest known self-antigens involved in autoimmunity. Numerous studies have implicated it in triggering and perpetuating the autoimmune response in autoimmune thyroid diseases (AITD). Indeed, traditional models of autoimmune thyroid disease, experimental autoimmune thyroiditis (EAT), are generated by immunizing mice with thyroglobulin protein in conjunction with an adjuvant, or by high repeated doses of Tg alone, without adjuvant. These extant models are limited in their experimental flexibility, i.e. the ability to make modifications to the Tg used in immunizations. In this study, we have immunized mice with a plasmid cDNA encoding the full-length human Tg (hTG) protein, in order to generate a model of Hashimoto's thyroiditis which is closer to the human disease and does not require adjuvants to breakdown tolerance. Human thyroglobulin cDNA was injected and subsequently electroporated into skeletal muscle using a square wave generator. Following hTg cDNA immunizations, the mice developed both B and T cell responses to Tg, albeit with no evidence of lymphocytic infiltration of the thyroid. This novel model will afford investigators the means to test various hypotheses which were unavailable with the previous EAT models, specifically the effects of hTg sequence variations on the induction of thyroiditis.

    Full Text Available The aim of the present study was to evaluate myocardial diastolic function in patients with autoimmune thyroiditis (AT against the TSH level within the reference range and subclinical interval as well as to determine whether it is related to the thyroid function or other metabolic and functional indices. METHODS. We studied diastolic function of left and right ventricles by the ratio of mitral and tricuspid annular early and late diastolic velocities (em/am and et/at respectively using tissue Doppler imaging; structural heart characteristics by echocardiography; lipid profile and peroxidation parameters; serum ferritin and iron concentrations in 132 middle-aged women. 36 of them were euthyroid controls, 96 had AT and were ranged according to their TSH value into 4 groups: women with “low- normal” (0.4–2.5 mU/L and “upper-normal” (2.5–4.0 mU/L TSH range; patients with subclinical hypothyroidism and TSH below and above 6 mU/L. RESULTS. The increase of TSH value within reference range and subclinical interval was associated with the parallel tendency to the em/am and et/at ratio decrease suggesting detrimental effect of the mildest thyroid failure on the left and right ventricles diastolic function. Thus, patients with TSH values >6 mU/L had significantly lower em/am and et/at ratio compared to the “low-normal” TSH group ( p < 0.05 and controls ( p < 0.01. Among them, the highest LDL cholesterol, myocardial mass index and oxidative stress rate were detected as well as lower iron and ferritin serum concentrations ( p < 0.05 compared to controls with regard to all the parameters listed above. Abnormalities in heart structure, lipid and iron metabolism correlated with alterations in ventricular relaxation suggesting that they can contribute, at least partly, to the diastolic dysfunction devel- opment CONCLUSION. The increase of TSH value within reference range and subclinical interval can affect diastolic function of the heart. Its

    Female patient (42 yr) suffered from autoimmune thyroiditis resulting in severe hypothyroidism. She was treated for several years by district physician with the dose of 150 microg L-thyroxine daily. Since the level of TSH was repeatedly very high and no improvement of clinical signs has been observed, she was referred to the Medical Faculty Hospital. Thyroid ultrasound showed remarkable diffuse hypoechogenicity, thyroid scintigraphy showed enlarged thyroid with low 99mTc uptake, TRH test was normal, thin needle biopsy supported autoimmune thyroiditis. X-ray examination showed normal sella turcica and no changes in the pituitary were observed with computer tomography. In spite of increasing the dose of peroral L-thyroxine to 300 microg/d and later to 500 microg/d the clinical status and TSH level did not improve. The patient was originally suspected from malabsorption of thyroxine. However, the test with a large single peroral dose (1000 microg) of L-thyroxine showed a rapid decrease of TSH level (from 126 to 75 mU/l) and increase of total T4 level (from 18 to 64 nmol/l) within 4 hr. Later the patient has been treated with intravenous L-thyroxine (500 microg every 3-4 days for 4 weeks) which resulted in the decrease of TSH level to 10 mU/l and increase of T4 level to 80-100 nmol/l. After that it was concluded that the problem is a poor compliance of the patient who apparently does not actually take the medication, although she always claimed that she is doing so. Referring to some similar cases described in the literature the case was classified as thyroxine pseudomalabsorption. In spite that this problem has been explained to her and her relatives, she refused to take any medication and is consistently neglecting all invitations to further examinations. PMID:11137979

    To investigate the expression of apoptosis-related protein (Fas, FasL, and Bcl-2) in the pathogenesis of autoimmune thyroid disorders (ATDs), immunohistochemical staining was performed on 20 Hashimoto's thyroiditis (HT), 20 Graves' disease (GD), and 20 thyroid follicular adenoma (TFA, as control). All the cases expressed Fas, mainly on the cell surface and cytoplasm. FasL was found in 17 cases of the TFA. Bcl-2 was detected in 15 cases of HT, 19 of GD and 17 of TFA. In TFA, a moderate Fas expression and a minimal or no FasL expression was detected on follicular cells. In HT, the follicles adjacent to infiltrating lymphocytes showed increased levels of Fas and FasL expression. A weaker staining of Fas and FasL was exhibited on infiltrating lymphocytes than on thyrocytes. In a comparison of GD with HT, thyrocytes and lymphocytes showed similar Fas staining, but for FasL the staining was rather weaker in HT. The expression of Bcl-2 was nearly identical in GD and TFA, but much weaker on the follicular cells in vicinity of lymphocytes and on the lymphocytes located in germinal centers of HT tissues. The expression of Fas, FasL, Bcl-2 in Hashimoto's thyroiditis and Graves' disease were almost same. FasL strong expression and Bcl-2 weak expression on the follicles in HT may induce apoptosis. These results provided evidence for expression of Fas, FasL and Bcl-2 in the pathogenesis of autoimmune thyroid disease. The lymphocytes seem not to be directly engaged in the process via their own FasL, but they may provide some cytokines that, in turn, upregulate Fas and/or FasL expression to induce apoptosis.

    Full Text Available Background: Follicular thyroid cancer (FTC metastasizes most commonly to the lungs and non-cranial bones. Skull and skin are uncommon sites and usually manifest well after the diagnosis of primary malignancy. Metastasis to skull and skin as the presenting feature of FTC is infrequently reported in the literature. Case presentation: A 65-year-old Caucasian woman with a history of thyroid nodule presented with the complaint of rapidly growing skull nodules which had been present for 3 years but were stable previously. She denied any fevers, chills, history of trauma, or weight loss. She denied any history of smoking or head and neck irradiation. On physical examination, she had two non-tender gray cystic lesions – one on her left temporal region and the other on the right parietal region. Biopsy was consistent with metastatic FTC. Magnetic resonance imaging of the brain demonstrated 7.1×3.8 cm and 3.7×4.5 cm fairly homogeneous, enhancing, relatively well-defined masses centered in the posterior and left anterior lateral calvarium with intracranial and extracranial extensions but without any vasogenic edema or mass effect on the brain. Thyroid ultrasound showed numerous nodules in both lobes. The patient underwent a total thyroidectomy. Histopathological studies of the thyroid gland revealed a well-differentiated FTC in the left lobe. Then she underwent resection of the tumor in multiple stages. She did not have any recurrence of the FTC or metastases during the follow-up period and will be receiving radioactive iodine treatment. Conclusion: Bone and lung are the common sites of metastasis from FTC, but involvement of skull or skin is unusual, particularly as the presenting feature. Metastases from FTC should be in the differential of patients with new osteolytic hypervascular skull lesions or cutaneous lesions in head and neck area.

    Full Text Available A tireoidite crônica auto-imune é, atualmente, a principal causa de hipotireoidismo e seu diagnóstico baseia-se nas manifestações clínico-laboratoriais. O marcador laboratorial mais importante é a presença de anticorpos antitireoglobulina e antiperoxidase, sendo este último o teste mais sensível. A biópsia aspirativa apresenta alta sensibilidade e especificidade, porém, é um método invasivo e, por isso, reservado para quando há presença de nódulo ou bócio de crescimento rápido. A cintilografia é desnecessária para o diagnóstico, já que apresenta baixa sensibilidade e especificidade. A ultra-sonografia, tanto ao modo B como ao dúplex-Doppler colorido, evoluiu de forma muito rápida e tornou-se um método simples, não-invasivo, reprodutível e com alta sensibilidade para o diagnóstico da tireoidite crônica auto-imune. Ao modo B, a ecogenicidade é um parâmetro de extrema importância, já que, além de apresentar alta correlação com o quadro citopatológico, também apresenta alta sensibilidade para o diagnóstico da tireoidite crônica auto-imune. Embora este parâmetro não seja específico da tireoidite crônica auto-imune, pois também pode estar presente na doença de Graves, na tireoidite pós-parto e na tireoidite subaguda, tais desordens podem ser facilmente diferenciadas tanto pelo quadro clínico-laboratorial quanto pelo dúplex-Doppler colorido. Assim, este artigo tem o objetivo de revisar a importância do estudo da ecogenicidade no diagnóstico da tireoidite crônica auto-imune.Chronic autoimmune thyroiditis is currently considered as the main cause for hypothyroidism and its diagnosis is based on clinical manifestations and laboratory tests results.

    Autoimmune thyroiditis (AT) is more prevalent in patients with chronic idiopathic urticaria CIU) than in the general population. Previous small studies without any controlled comparison reported that CIU remits in patients with CIU and AT treated with L-thyroxine. To determine whether l-thyroxine treatment can improve the clinical course of CIU in patients with the co-occurrence of AT and CIU. A total of 749 patients with CIU were retrospectively studied. Clinical and laboratory evaluation and classification of chronic urticaria were performed according to the EAACI/GA(2)LEN/EDF/WAO guidelines. After L-thyroxine treatment for 53 ± 19 days, euthyroidism was restored in all subjects. Urticaria activity score (UAS) was evaluated at baseline and after three and six months. The control group consisted of matched 44 euthyroid subjects with CIU. A total of 44 (5.9%) patients were diagnosed to have hypothyroidism related to AT. Autologous serum skin test (ASST) was found to be positive in 17 (38.6%) of them. There was no statistically significant difference in baseline UAS, between the ASST+ (3.94 ± 1.52) and the ASST- (3.63 ± 1.42; P = 0.27) hypothyroid subjects and the euthyroid CIU controls (3.73 ± 1.74). During the L-thyroxine treatment, a significant reduction of UAS was observed in both hypothyroid ASST+ and ASST- subjects. However, the mean UAS after three and six months of L-thyroxine treatment remained not significantly different from that in control euthyroid subjects with CIU. L-Thyroxine treatment has no effect on the course of CIU in patients with CIU and AT. PMID:22182385

    The objective of this study was to evaluate the association between maternal subclinical thyroid dysfunction and autoimmunity with the risk for intrauterine growth restriction (IUGR).Design is a systematic review and meta-analysis.A literature search was conducted using PubMed, Embase, and Cochrane database. A combination of 2 key words was used to search for the eligible studies: one indexed thyroid dysfunction or antithyroid antibodies; and the other one indexed the adverse neonatal outcomes of pregnancy, such as IUGR, small for gestational age, fetal growth restriction, or low birth weight.Two reviewers selected the studies, and eligible studies met the following criteria: prospective cohort studies or case control studies, studies of maternal thyroid dysfunction and positive antithyroid antibodies as the exposure of interest, and studies of IUGR or small for gestational age as the outcome of interest.Data were recorded, including data from maternal thyroid disorders and IUGR, and compared with a reference group.There were 22 individual data from the 13 cohort articles. Among these, 7 were focused on subclinical hypothyroidism (SCH), 4 on subclinical hyperthyroidism, 7 on positivity for thyroid peroxidase antibody (TPOAb), and 4 on isolated hypothyroxinemia. Meta-analysis showed that there was no effect of subclinical hyperthyroidism (odds ratio (OR) = 0.98; 95% confidence interval (CI), 0.40-2.41), TPOAb positivity (OR = 1.57; 95% CI, 0.77-3.18), or isolated hypothyroxinemia (OR = 1.05, 95% CI: 0.37-2.92) on IUGR. However, SCH is associated with IUGR (OR = 1.54; 95% CI, 1.06-2.25).SCH is associated with IUGR; however, subclinical hyperthyroidism, TPOAb positivity, or isolated hypothyroxinemia do not affect the risk of IUGR.

They were cultured 24 hours in 50 ml flasks at 37°C in a 5-95% CO2-air water-saturated atmosphere. After that, thyrocytes were identified by mouse mAb directed against human TPO epitope 64 conjugated with rabbit anti-mouse antibodies IgG (Fab'2 labeled by FITC. After incubation at room temperature to each of samples added reagent A fixative the cellular membrane. In next step into the cell suspensions were added reagent B to permeabilization of cellular membrane and specific anti-IL-4-PE or anti-IFN-γ-PE mAbs. Identification of intracellular cytokines in T lymphocytes was performed in the same procedure with application of anti-CD4-PerCP and anti-CD8-PerCP mAbs specific for T lymphocytes. The cells were analyzed in a flow cytometry (Coulter EPICS XL. Results In examined group of patients with GD we observed statistically significant higher mean percentage of cells with phenotype CD4+IL-4 (p Conclusions We conclude that human thyrocytes in autoimmune thyroid disorders could be a source of cytokine production and that their activation influences local interaction with T lymphocytes inflowing to the thyroid gland.

    Full Text Available Osseous metastasis in patients of thyroid carcinoma is not very common, and appendicular skeleton is very rare. Bone metastasis represents a complication, especially of follicular thyroid carcinoma and severely reduces the quality of life causing pain, and fractures. Diagnosis is typically done by correlating clinical suspicion with imaging. Occult clinical presentations usually delay the detection and management of patients with bone metastasis from thyroid carcinoma. There is limited information about the clinical presentations and prognosis of patients with follicular thyroid carcinoma with bone metastasis. We hereby present a case report of right arm swelling diagnosed as metastatic carcinoma having metastasis from thyroid primary.

    Background. Chronic autoimmune thyroiditis (CAT) frequently alters thyroid vascularization, likely as a result of the autoimmune process. Objective. To evaluate the effects of low-level laser therapy (LLLT) on the thyroid vascularization of patients with hypothyroidism induced by CAT using color Doppler ultrasound parameters. Methods. In this randomized clinical trial, 43 patients who underwent levothyroxine replacement for CAT-induced hypothyroidism were randomly assigned to receive either 10 sessions of LLLT (L group, n = 23) or 10 sessions of a placebo treatment (P group, n = 20). Color Doppler ultrasounds were performed before and 30 days after interventions. To verify the vascularity of the thyroid parenchyma, power Doppler was performed. The systolic peak velocity (SPV) and resistance index (RI) in the superior (STA) and inferior thyroid arteries (ITAs) were measured by pulsed Doppler. Results. The frequency of normal vascularization of the thyroid lobes observed in the postintervention power Doppler examination was significantly higher in the L than in the P group (P = 0.023). The pulsed Doppler examination revealed an increase in the SPV of the ITA in the L group compared with the P group (P = 0.016). No significant differences in the SPV of the STA and in the RI were found between the groups. Conclusion. These results suggest that LLLT can ameliorate thyroid parenchyma vascularization and increase the SPV of the ITA of patients with hypothyroidism caused by CAT. PMID:23316383

    This study was designed to understand the impact of self-antigen load on manifestation of organ specific autoimmunity. Using a transgenic mouse model characterized by CNS hypermyelination, we show that larger myelin content results in greater severity of experimental autoimmune encephalomyelitis attributable to an increased number of microglia within the hypermyelinated brain. We conclude that a larger self-antigen load affects an increase in number of tissue resident antigen presenting cells...

    Conclusion: The possibility of finding of an incidental metastatic tumor in the thyroid gland from a previous unknown and non-diganosed primary (as CCRC in our case was is rare and account only for less than 1% of malignancies. Nonetheless, the thyroid gland is a frequent site of metastasis and the presence of “de novo” thyroid nodules in oncologic patients must be always considered and studied.

    Full Text Available A total of 305 ambulatory patients recruited at the Division of Endocrinology, Hospital de Clínicas, University of Buenos Aires, with autoimmune thyroid disease (AITD were studied to search for associations between autoimmune thyroid disease and presence of serum markers of autoimmune diabetes mellitus. Screening for markers of pancreatic beta-cell autoimmunity was performed by radioligand binding assays (RBA as follows: autoantibodies to glutamic acid decarboxylase (GADA and proinsulin (PAA were determined in all sera, whereas autoantibodies to protein tyrosine phosphatase (IA-2A and insulin (IAA were additionally measured in 200 sera randomly selected from the total collection. In addition, every GADA positive serum among the remaining 105 sera was systematically tested for the presence of IA-2A and IAA. In the cohort of 305 AITD patients 22 (7.2% were previously diagnosed as type 1, type 2 or insulin-requiring type 2 diabetics. Ten of these patients presented serum marker positivity specific for β-cell autoantigens and 12 were marker negative. On the other hand, considering the majority of non-diabetic AITD patients (n=283, β-cell marker positivity was detected in 17 individuals (6.0%. The prevalence of autoimmune diabetes markers was much higher in the studied population than in the general population utilized as a control group, and GADA was the most frequent marker.Se investigó la asociación entre enfermedad tiroidea autoinmune y la presencia de marcadores séricos de diabetes mellitus en 305 pacientes ambulatorios con enfermedad tiroidea autoinmune reclutados en la División Endocrinología.

    AIM: To investigate the possible relationships between gastric autoimmune phenomena and clinical presentations of this disorder, in consecutive atrophic body gastritis patients.METHODS: A total of 140 atrophic body gastritis patients,diagnosed as consecutive outpatients presenting with macrocytic or iron deficiency anemia, or longstanding dyspepsia underwent gastroscopy with antral and body biopsies, assay of intrinsic factor, parietal cells and Helicobacter pylori(H pylori) antibodies. Gastritis was assessed according to Sydney System.RESULTS: Parietal cell antibodies were equally distributed in all clinical presentations, whereas the positivity of intrinsic factor antibodies (49/140, 35%) was significantly higher in pernicious anemia patients (49.2%) than in iron deficiency (21.1%) and dyspeptic patients (27.8%). No specific pattern of autoantibodies was related to the clinical presentations of atrophic body gastritis. A positive correlation was obtained between the body atrophy score and the intrinsic factor antibody levels (r = 0.2216,P = 0.0085). Associated autoimmune diseases were present in 25/140 (17.9%) patients, but the prevalence of autoimmune diseases was comparable, irrespective of the clinical presentations.CONCLUSION: The so-called hallmarks of gastric autoimmunity, particularly in intrinsic factor antibody cannot be usefully employed in defining an autoimmune pattern in the clinical presentations of ABG.

    The purpose of the investigation was to comparatively study the possible clinicodiagnostic and clinicoprognostic value of thyroglobulin (TG) autoantibodies (anti-TG autoAB) and thyroid peroxidase (TPO) (anti-TPO autoAB) with proteolytic activity (protease-AB) and to develop additional clinicoimmunological criteria for working out a protease-AB-based laboratory serodiagnosis protocol. Sera from 240 patients with autoimmune thyroiditis (AIT), 124 with diffuse toxic goiter (DTG), and 172 with other thyroid diseases were studied. Serum from 40 clinically healthy donors served as a control. Sera were screened for anti-TG and anti-TPO autoAB by enzyme immunoassay and/or radioimmunoassay. Nonspecific proteolytic activity was determined, by incubating a highly purified AB IgG-isotype solution with nonspecific substrate (such as BSA-FITS or thyoredoxine/Trx), followed by the measurement of relative fluorescence shifts at a wavelength of 470 nm. The blood samples taken from patients with AIT or DTG and the highly purified anti-TG or anti-TRO autoAB of IgG isotype were incubated with appropriate human substrates to determine AG-specific proteolytic activity. Proteolysis products were detected by PAAG electrophoresis. An association was found between the rise in the frequency of protease AB, their catalytic activity, a tendency toward autoAB between themselves, and the degree of thyroid tissue degradation in AIT and DTG; some specific features of a serological pattern were noted in diferent dorms of AIT and DTG. For example, the prevailing autoABs have been shown to be TG-specific in AIT and TPO-specific proteases in DTG; also, the detectable catalytic activity of both autoAB in AIT is an order of magnitude higher than that in DTG. No protease ABs have been recorded in other forms of thyroid diseases in which antithyroid autoABs are also frequently detected. The screening procedure for protease AB may be considered as a highly sensitive and specific indicator test in the

    Background. Mandatory iodine fortification of salt was introduced in Italy in 2005. The purpose of our study is to estimate the trend of thyroid diseases in Italy before and after mandatory iodization in Italy. Methods. 7976 patients (6802 females; 1174 males) were examined between 2003 and 2010. We divided the patients into categories according to their clinical diagnosis. Later, we evaluated for each patient if there was the positivity for antibodies anti TPO. Finally, we collected data about TSH values of all patients who did not use therapy for thyroid disease at the time of the examination. To evaluate the differences percentages for categorical variables, χ2-Pearson test was used; to evaluate the percentage differences of TSH values we used the Kruskal-Wallis test. Values were considered statistically significant at p < 0.05. Results. We considered diagnosis of "toxic adenoma / goiter", diagnosis of "Graves' disease" and diagnosis of "hyperthyroidism / thyrotoxicosis" before and after the introduction of mandatory iodization in Italy, to demonstrate the possible presence of iodine-induced hyperthyroidism. Diagnosis of toxic adenoma / goiter before 2005 were 3.7%, while after 2005 they were reduced to 3.1%. Diagnosis of Graves' disease before 2005 were 2.4%, and they remained unchanged after 2005. Finally, diagnosis of hyperthyroidism / thyrotoxicosis decreased from 2.5% to 2.1%. Comparing these results, there were no significant differences (P = 0.261) between the percentages of diagnosis of hyperthyroidism before and after the introduction of mandatory iodization. We considered diagnosis of Hashimoto's thyroiditis before and after 2005 to demonstrate a link between the administration of iodine and thyroid autoimmunity. Prevalence of Hashimoto's thyroiditis between 2003 and 2005 was 37%; prevalence between 2006 and 2010 dropped to 34.7%. This small difference has a borderline statistical significance (P = 0.049). Stratifying TSH values from year to year, we

    Full Text Available Context Autoimmune pancreatitis is a rare variant of chronic pancreatitis characterized by pancreatic ductal narrowing and pancreatic parenchymal edema on computed tomography and rarely with intermittent attacks of abdominal pain. Recently, it has been found to be a systemic disease with lymphoplasmacytic infiltration that has been associated with several autoimmune diseases and described in multiple organs including the extrahepatic bile duct, liver and gallbladder. Case report We describe the clinical, radiographic and histopathologic aspects of a patient who presented with synchronous masses in the pancreatic head and gallbladder. Postoperatively, the patient's jaundice subsided and IgG4 levels, which were drawn one week postoperatively, were all within normal limits. Nonetheless, immunohistochemical staining for IgG4 was positive. Conclusion Autoimmune pancreatitis is the most common benign entity identified in patients that underwent pancreaticoduodenectomy for presumed pancreatic adenocarcinoma. Our patient with autoimmune pancreatitis presented with simultaneous inflamematory masses in the gallbladder and pancreatic head, an association not previously reported. Preoperative evaluation of IgG4 or autoantibody levels may have obviated the need for an operation. Therefore, we have begun screening for elevated serum IgG4 concentrations to identify patients with possible autoimmune pancreatitis who present without definitive pathological or radiographic evidence for malignancy. If preoperative diagnosis is not made, immunohistochemical staining of pathology specimens can confirm the diagnosis.

    Full Text Available Abstract Women are more susceptible to a variety of autoimmune diseases including systemic lupus erythematosus (SLE, multiple sclerosis (MS, primary biliary cirrhosis, rheumatoid arthritis and Hashimoto's thyroiditis. This increased susceptibility in females compared to males is also present in animal models of autoimmune diseases such as spontaneous SLE in (NZBxNZWF1 and NZM.2328 mice, experimental autoimmune encephalomyelitis (EAE in SJL mice, thyroiditis, Sjogren's syndrome in MRL/Mp-lpr/lpr mice and diabetes in non-obese diabetic mice. Indeed, being female confers a greater risk of developing these diseases than any single genetic or environmental risk factor discovered to date. Understanding how the state of being female so profoundly affects autoimmune disease susceptibility would accomplish two major goals. First, it would lead to an insight into the major pathways of disease pathogenesis and, secondly, it would likely lead to novel treatments which would disrupt such pathways.

  6. Thyroid and menopause.

    Thyroid dysfunction is common in the general population especially in women. All thyroid diseases are in fact more common in women than in men and may interfere with the reproductive system. Thyroid function and the gonadal axes are related throughout the woman's fertile period. The relationship between the two glands is mutual. In particular, thyroid hormones affect the reproductive function both directly and indirectly through several actions. Studies on the relationship between menopause and thyroid function are few and do not allow to clarify whether menopause has an effect on the thyroid regardless of aging. With aging, the main changes regarding thyroid physiology and function are: a reduction of thyroid iodine uptake, free thyroxine and free triiodothyronine synthesis and catabolism of free thyroxine while reverse triiodothyronine increases; the level of thyroid stimulating hormone remains normal with sometimes a tendency to higher limits. These changes are present in both sexes without distinction between males and females. The complexity of the relationships can be summarized in three aspects: thyroid status does not influence significantly the climacteric syndrome; menopause may modify the clinical expression of some thyroid diseases, particularly the autoimmune ones; thyroid function is not directly involved in the pathogenesis of the complications of menopause. However, coronary atherosclerosis and osteoporosis may be aggravated in the presence of hyperthyroidism or hypothyroidism. The effects of postmenopausal estrogen replacement on thyroxine requirements in women with hypothyroidism should be considered. PMID:23998691

Our aim was to assess whether these conditions are associated with changes in the health-related quality of life (HRQOL in pediatric patients with T1D. In a cross-sectional study we identified eligible 332 patients with T1D aged 8–18 years, of whom 248 (75% together with their parents responded to the PedsQL Generic and Diabetes Modules. Compared to 143 patients without thyroid autoantibodies, 40 patients with a thyroxine-treated AITD scored lower in the overall generic HRQOL (P=0.014, as well as in the overall diabetes-specific HRQOL (P=0.013. After adjustment for age, gender, duration of diabetes, type of diabetes treatment, and diabetes control, this association remained statistically significant for the generic HRQOL (P=0.023. Celiac disease was not associated with a change in the generic or diabetes-specific HRQOL (P=0.07  and   P=0.63, resp.. Parental scores showed no association with AITD or celiac disease, except a marginally significant decrease in the overall generic HRQOL (P=0.039 in the T1D + AITD compared to T1D group. Our study indicates that, in pediatric patients with T1D, concomitant thyroxine-treated AITD is associated with lower quality of life.

    Graves' disease (GD) is an autoimmune disease of the thyroid gland caused by autoantibodies against thyroid-stimulating hormone receptor (TSHR). Currently, the diagnostic test for TSHR autoantibodies is based on an indirect competitive binding assay that measures the ability of TSHR autoantibodies to inhibit the binding of thyroid-stimulating hormone (TSH) to TSHR. Here, we have developed a specific and direct diagnostic method for autoantibodies in GD that incorporates immobilized TSHR-containing recombinant proteoliposomes into an enzyme-linked immunosorbent assay (ELISA). To reduce non-specific binding of autoantibodies to recombinant proteoliposomes, we investigated the effect of polyethylene glycol (PEG)-lipid on the binding of commercially available anti-TSHR antibodies (aTSHRAb). The incorporation of PEG-lipids into liposomes decreased non-specific binding, as compared to liposomes that did not contain PEG-lipids, and the addition of blocking reagents further decreased non-specific reactivity. aTSHRAb exhibited higher reactivity towards PEG-modified TSHR recombinant proteoliposomes than PEG-modified liposomes without TSHR (bare liposomes). Importantly, serum autoantibodies from patients with GD, which is associated with hyperthyroidism, exhibited remarkably specific binding to TSHR recombinant proteoliposomes. Serum autoantibodies from patients with Hashimoto's disease (HD), which is associated with hypothyroidism, also reacted specifically with proteoliposomal TSHR. These results suggest that immobilized TSHR recombinant proteoliposomes can serve as a direct diagnostic test for GD and HD. Furthermore, given that there is no competition test currently available for detecting autoantibodies in HD, the combination of TSHR recombinant proteoliposome ELISA and indirect competitive TSHR binding assay might be an effective way to discriminate between GD and HD.

    Objective Robot-assisted endoscopic surgery has been increasingly accepted because of its unique three-dimensional vision and precise simulation-based technology.However,the utilization of robotic systems in thyroid surgery is limited.We conducted a systematic review to assess the application and development of robot-assisted endoscopic surgical technique in thyroid surgery.Data sources Articles published in PubMed before June,2011 about robot-assisted endoscopic surgery were selected.Study selection Original articles and critical reviews selected were related to robot-assisted (thyroid) surgery or endoscopic thyroid surgery,and a total of 3540 relevant articles were retrieved and 34 were finally cited.Results Robot-assisted operation of benign thyroid diseases were successfully performed,although the operation time is too long to exhibit its advantages.Nevertheless,the superiority of robot-assisted endoscopic surgical technique compared to conventional endoscopic surgery in the treatment of thyroid carcinoma were obvious,since robotic radical thyroidectomy with central and lateral neck lymph node dissection could be achieved while maintaining operative results and cosmetic outcomes equivalent to or better than conventional endoscopic surgery.Furthermore,the learning curve duration of robot-assisted endoscopic thyroid surgery was shorter than that of conventional endoscopy,especially for the novices without any endoscopic surgical basis.Conclusion Robot-assisted endoscopic thyroid surgery,with its safety,feasibility,thoroughness,cosmetic benefits,and ability to overcome the limitations of conventional endoscopic surgery,will be further improved and applied,and is worthy of attention.

    2013-01-01

    Full Text Available Thyroid surgeons are becoming increasingly more aware of a histologically distinct subset of thyroid carcinoma whose classification falls between well-differentiated and anaplastic carcinomas with respect to both cell differentiation and clinical behavior. This subtype of tumors has been categorized as poorly differentiated or insular carcinoma, based on its characteristic cell groupings. Although the differentiation of insular carcinoma from other thyroid carcinomas has important prognostic and therapeutic significance, relatively little about insular carcinoma has been published in the otolaryngology literature. In this article, we discuss a case of insular carcinoma of thyroid presenting with concurrent distant metastasis to skull, lung, ribs, and inguinal region with review of the literature. We conclude that insular thyroid carcinoma warrants aggressive management with total thyroidectomy and excision of accessible giant lesion followed by radioactive iodine ablation of any remaining thyroid tissue.

    Full Text Available Abstract Background Ophthalmopathy is a common manifestation of Graves’ disease (GD occurring in up to 50% of patients. Mild eye signs are also common in patients with Hashimoto’s thyroiditis. Whilst a genetic predisposition to GD has been demonstrated this is not the case for the ophthalmopathy which often runs a separate course. Objective We determined the prevalences of eye and eyelid signs and positive thyroid and orbital antibody tests in first and second degree relatives from a single family with multiple cases of Graves’ disease, ophthalmopathy and Hashimoto’s thyroiditis. Design The study cohort comprised 16 subjects from the same family, 4 probands namely, 3 with GD and one with Hashimoto’s thyroiditis and hypothyroidism and 12 of their euthyroid first or second degree relatives. We measured antibodies against calsequestrin (CASQ1 and collagen XIII in an enzyme-linked-immunosorbent assays and TSH-Receptor (TSH-R antibodies as i TSH-R binding inhibiting immunoglobulin (TBII and ii thyroid stimulating immunoglobulin (TSI. Eye signs were classified and quantified using the clinical activity score (CAS, NOSPECS classes, Nunery types 1 and 2 and the margin-reflex-distance (MRD as a measure of upper eyelid retraction (UER. Main outcomes Whilst significant ophthalmopathy was uncommon in the relatives, mild eye signs, in particular UER, were demonstrated in about a third of them. The presence of eye signs was moderately, but not significantly, associated with the detection of CASQ1 and collagen XIII antibodies, but not TSH-R antibodies. Conclusion Our study demonstrates a significant prevalence of positive orbital antibody tests and ophthalmopathy in probands with thyroid autoimmunity and their euthyroid relatives, favouring a role of genetic factors in the development of ophthalmopathy in patients with thyroid autoimmunity.

    Autoimmune myelofibrosis is a distinct clinicopathologic entity that occasionally occurs with autoimmune disorders such as systemic lupus erythematosus (SLE) and rheumatoid arthritis. Most cases of autoimmune myelofibrosis have been reported in female patients with a known history of SLE. We report a case of a middle-aged male patient with an unusual presentation of SLE and autoimmune myelofibrosis who presented only with severe anemia initially and was later diagnosed with SLE and autoimmune myelofibrosis. The patient's condition improved dramatically after treatment with corticosteroids.SLE and autoimmune myelofibrosis is a rare but potentially devastating condition. Anemia maybe the only presenting symptom in addition to bone marrow fibrosis and careful clinical and laboratory assessment is imperative. Corticosteroids maybe useful and spare patients from bone marrow transplantation. PMID:25984660

    Full Text Available Background: Autoimmune hepatitis (AIH is a form of chronic hepatitis with unclear causative factors and is characterized by immunological and auto-immunological manifestations. Several extrahepatic manifestations, such as other autoimmune disorders, are associated with AIH. AIH with dermatological conditions as the initial manifestation is rare. We report the case of AIH in which erythema nodosum (EN was the first manifestation.Case Presentation: An 8-year-old girl with several persistent dermatological lesions was referred to our hospital several months ago. Her skin had nodular, painful, dry, and erythematous lesions, predominantly on the extensor areas of both the legs, with some erythematous patches on her face. Physical examination revealed that she had hepatosplenomegaly as well. Skin biopsy indicated EN. The results of the laboratory tests showed increased levels of several liver enzymes. The patient's International Autoimmune Hepatitis Group (IAIHG score was a definite indicator of AIH. The results of liver biopsy indicated AIH. Other causes of EN and abnormal liver function were ruled out. The only obvious cause of skin lesions was chronic inflammation due to an autoimmune response. The patient was treated for AIH, and her skin lesions along with other signs and symptoms resolved.Conclusions: AIH can present with protean clinical manifestations, and is thus associated with the risk of delayed diagnosis. Dermatological manifestations, including EN, could indicate a serious disease, and further investigation might be required. AIH should be considered as the possible diagnosis in such cases.

    Full Text Available Silent thyroiditis is a rare cause of thyrotoxic periodic paralysis. The objective was to present a case of silent thyroiditis presenting as periodic paralysis. A 23-year-old man presented with recurrent acute flaccid predominantly proximal weakness of all four limbs. He had a similar episode 3 weeks back. On examination he was found to have hypokalemia secondary to thyrotoxicosis. Clinically there were no features of thyrotoxicosis or thyroiditis. He was initially treated with intravenous and later oral potassium supplementation and propranolol. At 8 weeks of follow-up his thyroid profile became normal and his propranolol was stopped. He had no further recurrence of paralysis. He was diagnosed as a case silent thyroiditis presenting as thyrotoxic periodic paralysis. In cases of recurrent or acute flaccid muscle paralysis, it is important to suspect thyrotoxicosis, even if asymptomatic. Definitive treatment of thyrotoxicosis prevents recurrence.

    Full Text Available Subjects at risk for major mood disorders have a higher risk to develop autoimmune thyroid disease (AITD and vice-versa, implying a shared pathogenesis. In mood disorder patients, an abnormal profile of hematopoietic/neuronal growth factors is observed, suggesting that growth/differentiation abnormalities of these cell lineages may predispose to mood disorders. The first objective of our study was to investigate whether an aberrant profile of these hematopoietic/neuronal growth factors is also detectable in subjects at risk for AITD. A second objective was to study the inter relationship of these factors with previously determined and published growth factors/cytokines in the same subjects.We studied 64 TPO-Ab-negative females with at least 1 first- or second-degree relative with AITD, 32 of whom did and 32 who did not seroconvert to TPO-Ab positivity in 5-year follow-up. Subjects were compared with 32 healthy controls (HCs. We measured serum levels of brain-derived neurotrophic factor (BDNF, Stem Cell Factor (SCF, Insulin-like Growth Factor-Binding Protein 2 (IGFBP-2, Epidermal Growth Factor (EGF and IL-7 at baseline.BDNF was significantly lower (8.2 vs 18.9 ng/ml, P<0.001, while EGF (506.9 vs 307.6 pg/ml, P = 0.003 and IGFBP-2 (388.3 vs 188.5 ng/ml, P = 0.028 were significantly higher in relatives than in HCs. Relatives who seroconverted in the next 5 years had significantly higher levels of SCF than non-seroconverters (26.5 vs 16.7 pg/ml, P = 0.017. In a cluster analysis with the previously published growth factors/cytokines SCF clustered together with IL-1β, IL-6 and CCL-3, of which high levels also preceded seroconversion.Relatives of AITD patients show aberrant serum levels of 4 hematopoietic/neuronal growth factors similar to the aberrancies found in mood disorder patients, suggesting that shared growth and differentiation defects in both the hematopoietic and neuronal system may underlie thyroid autoimmunity and mood disorders.

    We report a case of 36-year-old woman, admitted for hypotonic tetraparesis. Laboratory tests revealed severe hypokalaemia, acidosis, hyperchloremia and alkaline urinary pH allowing the diagnosis of distal tubular acidosis. Additional investigations led to the diagnosis of primary Sjögren's syndrome associated with Hashimoto's thyroïditis. The evolution was favorable under potassium citrate alkalinisation, the corticosteroid therapy and hormonal substitution. Based on this observation, the pathogenesis of distal tubular acidosis during auto-immune diseases (Sjögren's syndrome, monoclonal hypergammaglobulinemia, hypothyroidism) was discussed as well as its consequences and management.

    AIM: To evaluate the prevalence of autoantibodies in chronic hepatitis C virus (HCV)-infected children focusing on thyroid autoimmunity.METHODS: We investigated the prevalence of autoantibodies in 123 chronic HCV-infected children before,during and after monotherapy with interferon-alpha (TFN-α) or combined treatment with interferon-α or peginterferon-α and ribavirin. Besides antibodies against smooth muscle (SMA), nuclei (ANA), and liver/kidney microsomes (LKM), the incidence of antithyroid peroxidase antibodies as well as thyroid function parameters (TSH, FT3 and FT4) were determined.RESULTS: We found that 8% of children had autoantibodies before treatment. During treatment,18% of children were found positive for at least one autoantibody; 15.5% of children developed pathologic thyroid values during IFN-α treatment compared to only one child before therapy. Six children had to be substituted while developing laboratory signs of hypothyroidism.CONCLUSION: Our data indicate a strong correlation between interferon-α treatment and autoimmune phenomena, notably the emergence of thyroid antibodies. The fact that some children required hormone replacement underlines the need of close monitoring in particularly those who respond to therapy and have to be treated for more than 6 mo.

    2011-01-01

    The authors describe an unusual case of metastatic thyroid follicular adenocarcinoma presenting with sciatica in a 79-year-old woman. The primary thyroid tumour was undiagnosed until this clinical presentation. The patient gave a short history of back pain and right-sided sciatica, which was progressive and nocturnal in nature. Neuroimaging revealed an enhancing intradural mass lesion, which was completely excised through a right L1-L3 hemilaminectomy. Histopathological examination of the excised tissue revealed a follicular thyroid carcinoma. Subsequent metastatic investigation revealed a heterogeneously attenuating mixed solid cystic mass in a retrosternal thyroid gland, with multiple solid pulmonary nodules suggestive of metastatic disease. She opted for palliative radiotherapy for the primary thyroid cancer and made remarkable postoperative improvement. The authors conclude that surgical treatment of solitary metastatic lesion may produce good symptomatic relief irrespective of patient\\'s age and primary pathology, while emphasising the need for detailed clinical evaluation of patients with \\'red flag\\' symptoms.

    It is well recognized that the use of external irradiation of the head and neck to treat patients with various non-thyroid disorders increases their risk of developing papillary thyroid carcinoma years after radiation exposure. An increased risk of thyroid cancer has also been reported in survivors of the atomic bombs in Japan, as well as in Marshall Island residents exposed to radiation during the testing of hydrogen bombs. More recently, exposure to radioactive fallout as a result of the Chernobyl nuclear reactor accident has clearly caused an enormous increase in the incidence of childhood thyroid carcinoma in Belarus, Ukraine, and, to a lesser extent, in the Russian Federation, starting in 1990. When clinical and epidemiological features of thyroid carcinomas diagnosed in Belarus after the Chernobyl accident are compared with those of naturally occurring thyroid carcinomas in patients of the same age group in Italy and France, it becomes apparent that the post-Chernobyl thyroid carcinomas were much less influenced by gender, virtually always papillary (solid and follicular variants), more aggressive at presentation and more frequently associated with thyroid autoimmunity. Gene mutations involving the RET proto-oncogene, and less frequently TRK, have been shown to be causative events specific for papillary cancer. RET activation was found in nearly 70% of the patients who developed papillary thyroid carcinomas following the Chernobyl accident. In addition to thyroid cancer, radiation-induced thyroid diseases include benign thyroid nodules, hypothyroidism and autoimmune thyroiditis, with or without thyroid insufficiency, as observed in populations after environmental exposure to radioisotopes of iodine and in the survivors of atomic bomb explosions. On this basis, the authors evaluated thyroid autoimmune phenomena in normal children exposed to radiation after the Chernobyl accident. The results demonstrated an increased prevalence of circulating thyroid

  6. Allosuppressor T lymphocytes abolish migration inhibition factor production in autoimmune thyroid disease: evidence from radiosensitivity experiments

    International Nuclear Information System (INIS)

    The ability of normal T lymphocytes to abolish the production of migration inhibition factor by antigen-sensitized T lymphocytes of Graves' disease (GD) and Hashimoto's thyroiditis (HT) in response to thyroid antigen has been studied by a modified migration inhibition factor test using isolated T lymphocytes alone. The production of migration inhibition factor was consistently abolished when normal T lymphocytes were mixed with GD or HT T lymphocytes in various ratios (1:9, 2:8, 5:5) as reported previously (Okita et al., 1980b). However, prior in-vitro irradiation (1000 rad) of the normal T lymphocytes resulted in loss of their ability to abolish migration inhibition factor production by the antigen-sensitized T lymphocytes of GD and HT. The effect is consistent with the radiosensitivity of suppressor T lymphocytes and indicates that the effect of normal T lymphocytes on GD and HT T lymphocytes is one of allosuppression. The results support the view that there is a defect in suppressor T cell function in GD and HT. (author)

    Full Text Available Introduction. We hereby describe the case of a young female patient who presented with pseudothrombotic microangiopathy, as well as pancytopenia accompanied by autoimmune atrophic gastritis. Case Presentation. A 36-year-old Caucasian woman presented to the emergency department with fatigue and dyspnea on minimal exertion. Physical examination was unremarkable except for pallor and noninjected conjunctiva. Laboratory tests revealed high LDH and low hemoglobin, white blood cells, platelets, and haptoglobin. The peripheral blood smear showed schistocytes suggestive of pseudothrombotic microangiopathy. Low cobalamin level and hyperhomocysteinemia were also detected. Autoimmune atrophic gastritis was confirmed by gastric biopsy and positive anti-intrinsic factor antibodies. Vitamin B12 supplements were given which led to rapid recovery and normalization of blood parameters. Conclusion. This case highlights the importance and serves as a reminder to clinicians to rule out cobalamin deficiency and autoimmune atrophic gastritis in patients presenting with a picture suggestive of thrombotic thrombocytopenic purpura and pancytopenia, which was completely reversible after appropriate replacement therapy without recurring to unnecessary and invasive procedures such as plasma exchange.

    The induction and maintenance of T cell tolerance is essential to prevent autoimmunity. A combination of central and peripheral mechanisms acts to control autoreactive T cells. In secondary lymphoid organs, dendritic cells (DCs) presenting self-antigen were thought to play a major role in the induction of peripheral T cell tolerance. Multiple recent studies have demonstrated that DCs are not absolutely essential to induce and maintain tolerance. Furthermore, it has also been recently shown th...

    Full Text Available Introduction. The aim of this study was to estimate the significance of TSH, thyroid peroxidase antibody (TPOAb, and mild (subclinical hypothyroidism in women from The Danish General Suburban Population Study (GESUS on the number of children born, the number of pregnancies, and the number of spontaneous abortions. Methods. Retrospective cross sectional study of 11254 women participating in GESUS. Data included biochemical measurements and a self-administrated questionnaire. Results. 6.7% had mild (subclinical hypothyroidism and 9.4% prevalent hypothyroidism. In women with mild hypothyroidism TPOAb was significantly elevated and age at first child was older compared to controls. TSH and TPOAb were negatively linearly associated with the number of children born and the number of pregnancies in the full cohort in age-adjusted and multiadjusted models. TSH or TPOAb was not associated with spontaneous abortions. Mild (subclinical hypothyroidism was associated with a risk of not having children and a risk of not getting pregnant in age-adjusted and multiadjusted models. Prevalent hypothyroidism was not associated with the number of children born, the number of pregnancies, or spontaneous abortions. Conclusion. Impaired fertility is associated with TSH, TPOAb, and mild (subclinical hypothyroidism in a Danish population of women.

    Autoimmune thyroid diseases (AITD) including Graves' disease (GD) and Hashimoto's thyroiditis (HT) are complex genetic diseases. Cytokines IL-1B and IL-4 play a role in the pathogenesis of AITD. This study was conducted on Tunisian patients with GD or HT to investigate the association of IL-1B and IL-4 gene polymorphisms with the risk and the prognosis of AITD. A total of 358 healthy controls and 341 patients with AITDs (249 HT and 92 GD) were genotyped for IL-1B+3953C/T and IL-4 intron 3 VNTR polymorphisms. A significant association was found between IL-1B+3953C/T polymorphism and GD or HT, both in the dominant and additive models. The IL-1B+3953T allele was associated with GD (p = 0.0003, OR = 1.93, CI = 1.34-2.78) and HT (p = 0.009, OR = 1.43, CI = 1.09-1.88). The IL-4 VNTR polymorphism was associated only with HT risk both in additive (p = 0.03, OR = 0.31, CI = 0.11-0.86) and recessive (p = 0.03, OR = 3.04, CI = 1.13-8.17) models. No significant association was found between IL-1B+3953C/T polymorphism and change in the serum concentrations of TSH and FT4 in GD and HT patients. In HT patients, the IL-1B+3953T allele (p = 0.009, OR = 0.42, CI = 0.22-0.83) and the IL-1B+3953T/T genotype (p = 0.03, OR = 0.21, CI = 0.04-1.07) were more frequent in the absence than in the presence of an anti-TPO antibody. The proportion of HT patients with the P1P2 genotype of the IL-4 gene was significantly higher in the absence than in the presence of the anti-TPO antibody (p = 0.04, OR = 0.39, CI = 0.17-0.89). These preliminary results suggest that IL-1B and IL-4 gene polymorphisms may be associated with GD and HT susceptibility and may represent prognostic factors for predicting the severity of HT.

    Full Text Available The aspects of autoimmune thyroiditis (AIT remain quite actual, since many issues of etiology, pathogenesis, morphology, classification, diagnostics, therapy and prediction of this disorder are far from final solution. Since disturbances of fine molecular immune mechanisms underlie pathogenesis of either immune disorder, the genes coding its main components, are regarded as potential candidate genes predisposing for AIT, e.g., genes of surface antigen (CTLA-4 and protein tyrosine phosphatase non-receptor 22 (PTPN-22. We have performed genotyping of 298 Tatar women in Tatar Republic (Russia with respect to age and biochemical parameters (control group, 137 persons; AIT group, 161 patients. The following gene polymorphisms were tested: +49 А/G, -318 С/Т, -1661 А/G of СТLA-4 gene, and 1858 С/Т polymorphism of PTPN-22 gene. Genotyрing was performed by PCR-RFLP method as described earlier. The data were analyzed using Chi-square test and 95% confidential interval (CI. The frequencies of CTLA-4 -1661 G allele and genotype A/G and +49 G/A G allele and genotype GG carriers were significantly higher in AIT patients than in controls (P = 0.04, OR 1.84, 95% CI 2.31-1.4; P = 0.001, OR 2,0 95% CI 1.62-2.31 respectively, with increased contents of serum antibodies to thyroglobulin (OR, 1.56, 95% CI 2.25-3.6; OR 1.12, 95% CI 1.9-2.75, respectively and to thyroperoxidase (OR 1.3, 95% CI 1.5-4.1 for G/G genotype of +49 A/G polymorphism, independently of age (р < 0,05. We showed that the combinations of A/G, T/C and G/G genotypes of -1661 A/G, -318 T/C and +49 G/A polymorphisms is associated with increased risk of genetic predisposition to ITD in Tatar women (OR 7.87, 95% CI 2.03-3.25. A strong association was also observed between the increased level of antibodies to TPO (> 1000 ME/l and GG genotype of +49 G/A polymorphism (OR 1.3, 95% CI 1.5-4.1 and antibodies to TG (> 100 ME/l and genotypes A/G and G/G of CTLA-4 -1661 A/G and +49 G/A polymorphisms

    Full Text Available A 31-year-old male patient presented with a rapidly growing neck mass with normal thyroid function tests. Ultrasonography showed thyroidal expansion, a hypoechoic nodule that completely filled the right lobe, and 2 hypoechoic lymphadenopathies in the right jugulodigastric chain. The patient underwent right total and left subtotal thyroidectomy, following the diagnosis of nodular goiter; however, postoperative histopathological evaluation demonstrated primary Burkitt’s lymphoma of the thyroid gland. The tumor was staged as stage 1, and R-hyper-CVAD protocol (rituximab, hyperfractionated cyclophosphamide, vincristine, doxorubicin and dexamethasone was administered. The protocol was changed to R-CHOP after 4 cycles due to recurrent grade III/IV cytopenias and febrile neutropenia. The PET-CT scans performed after chemotherapy and at the 6-month follow-up were normal. In summary, we reported a case with a diagnosis of Burkitt’s lymphoma, which is a rare type of primary thyroid lymphoma.

    Full Text Available Among bullous diseases, pemphigus vulgaris (PV is a classical variety of this type of skin disorders. To establish the real prevalence of thyroid abnormalities in such a disease, a prospective study was developed. For this reason, thyroid evaluation was performed in 15 consecutive patients who attended the Dermatology Clinic for PV and in a group of 15 healthy volunteers (Control Group matched by age and gender. Thyroid function was evaluated by measuring T3, T4 and TSH. The presence or absence of goiter was searched by palpation, while thyroid autoimmunity was investigated through the assay of thyroperoxidase antibodies (TPO-Ab. In each group there were 9 women and 6 men, aging 25-65 years (mean = 48.3 y in the PV Group, and 25-69 years (mean = 45.4 y in the Control Group.

    Autoimmune thyroid disease is the predominant form of thyroid dysfunction in the developed world. Although its precise cause is currently unclear, principles of management have been established. There is a vigorous debate about the management of the increasingly commonly recognised subclinical forms of thyroid dysfunction despite recent recommendations. Nodular thyroid disease and thyroid carcinoma have received wide attention. The effects of drugs and pregnancy on thyroid function have also ...

    AIM: To investigate some possible etiologies of achalasia by screening patients with achalasia for some autoimmune diseases such as thyroid disease.METHODS: We examined 30 known cases of achalasia (20 females, 10 males). Their age ranged 15-70 years.All of them were referred to our institute for treatment.Their sera were evaluated to detect some possible associations with rheumatoid disease, thyroid disease,inflammatory process, anemia, etc.RESULTS: Seven out of 30 patients (23%) had thyroid disease including four patients with hypothyroidism (13.3%), two patients with hyperthyroidism (6.6%),and one had only thyroid nodule but was in euthyroid state (3.3%). Two of these hypothyroid patients had no related clinical symptoms (subclinical) and two had clinical manifestations of hypothyroidism. There were no correlations between the intensity of thyroid diseases and the severity of achalasia symptoms.CONCLUSION: The etiology of achalasia is unknown although autoimmunity has been implicated and is supported by several studies. Thyroid disease presents concomitantly with achalasia in about one fourth of our patients who may have a common etiology.

    It has long been known that the thyroid depends upon the environment for regular iodine supply, avoiding iodine deficiency or excess. Thyroid function may be altered by natural compounds present in water or foodstuff (such as iodine or phyto-goitrogens), or by synthetic compounds, either administered knowingly (in case of medicine), or as an untoward event in case of exposure to industrial products and pesticides, massively produced and polluting the environment. Compounds with an impact on thyroid homeostasis are called thyroid disruptors (TD). TD may disrupt the thyroid economy at any level of regulation: thyroid hormone synthesis, metabolism, or transport; cellular level including thyroid hormone signaling; tumorigenesis or more indirectly via the triggering of an autoimmune process. Compounds such as polychlorinated biphenyls (PCBs) may act at multiple levels. PT effects on human health depend on parameters linked to the individual person (age at exposure, iodine status, diet, professional exposure, place of living, family history of thyroid disease, detoxification enzyme genetic variants) and on parameters linked to the compounds themselves (chemical structure, lipo- or hydro-solubility, modes of exposure, metabolites activity, "cocktail effect"). The toxic effects of TD do not necessarily follow the rules of classical toxicology (low-dose effects, non-monotonic curves). The main clinical risks are the deleterious impact on neurocognition and behavior for the fetus and the young child, and possibly the elderly, while in adults the main concerns are tumori/goitrogenesis and autoimmune thyroid disease. The potential socioeconomic impact for society warrants an active and major involvement in research to find solutions in a multidisciplinary approach. PMID:26603908

  7. Thyroid

    International Nuclear Information System (INIS)

    In vivo thyroid function testing is conducted with isotopes of iodine, the rate-limiting substrate for thyroid hormonogenesis, or with pertechnetate, an anion which the thyroidal follicular cells will concentrate or trap similarly to iodide, but will not organify. The physical characteristics of these isotopes, their advantages or indications, their disadvantages, and the average radiation dose to the thyroid in the infant, child, and adult are reviewed. The latter is expressed as estimated dose in rads per microcurie administered assuming an uptake of 27 percent and a biological half-life of 68 days. For many years the standard isotope for thyroid studies has been 131I. This isotope, however, has the disadvantage of a high radiation dose to the gland, especially in infants and children. Furthermore the high-energy gamma ray (364 keV) requires low-efficiency, thick septal collimators for scanning. More recently 125I, 123I, and 99/sup m/Tc-pertechnetate have been used. (auth)

  8. Elevation of corticosteroid-binding globulin in Obese strain (OS) chickens: possible implications for the disturbed immunoregulation and the development of spontaneous autoimmune thyroiditis

    International Nuclear Information System (INIS)

    Basal plasma levels of corticosterone and corticosteroid-binding globulin (CBG) have been investigated in Obese strain (OS) chickens afflicted with spontaneous autoimmune thyroiditis (SAT). Corticosterone was determined radioimmunologically, and CBG by using a highly sensitive radioligand saturation assay. OS chickens displayed total corticosterone levels not different from healthy normal White Leghorn (NWL) chickens. CBG, however, was found to be twice as high in OS chickens as compared with their healthy counterparts, irrespective of sex or age. This quantitative difference in the CBG level is not compensated for by either altered affinity or specificity of the molecule. Furthermore, no differences were found in the response of OS and NWL lymphocytes to the suppressive effect of glucocorticoids in vitro. It was therefore assumed that OS animals are deficient in free, hormonally active corticosterone. An additional indication for such a diminished glucocorticoid tonus was that in vivo treatment of OS chickens with glucocorticoid hormones, thus increasing the free and active hormone fraction, normalizes the T cell hyperreactivity and significantly reduces thyroid infiltration. Possible pathophysiological implications of a diminished glucocorticoid tonus for spontaneous autoimmunity, as well as possible explanations for the beneficial effects of glucocorticoid treatment on the development of SAT, are discussed

  9. In vivo evidence for CD4+ and CD8+ suppressor T cells in vaccination-induced suppression of murine experimental autoimmune thyroiditis

    International Nuclear Information System (INIS)

    In several experimental autoimmune diseases, including experimental autoimmune thyroiditis (EAT), vaccination with attenuated autoantigen-specific T cells has provided protection against subsequent induction of disease. However, the mechanism(s) of vaccination-induced suppression remains to be clarified. Since the authors have previously shown that suppression generated by pretreatment with mouse thyroglobulin (MTg) or thyroid-stimulating hormone in EAT is mediated by CD4+, not CD8+, suppressor T cells, they examined the role of T cell subsets in vaccination-induced suppression of EAT. Mice were vaccinated with irradiated, MTg-primed, and MTg-activated spleen cells and then challenged. Pretreatment with these cells suppressed EAT induced by immunization with MTg and adjuvant, but not by adoptive transfer of thyroiditogenic cells, suggesting a mechanism of afferent suppression. The activation of suppressor mechanisms did not require CD8+ cells, since mice depleted of CD8+ cells before vaccination showed reduced EAT comparable to control vaccinated mice. Furthermore, depletion of either the CD4+ or the CD8+ subset after vaccination did not significantly abrogate suppression. However, suppression was eliminated by the depletion of both CD4+ and CD8+ cells in vaccinated mice. These results provide evidence for the cooperative effects of CD4+ and CD8+ T cells in vaccination-induced suppression of EAT

    Full Text Available Context: Follicular thyroid cancer rarely manifests itself as a distant metastatic lesion. Case Report: We report a case of a 41-year old man presented with a solid mass located in the left temporo-occipital region. The 3D computed tomography showed a large solid mass with high vascularity, skull erosion and supra-infratentorial epidural mass effect. After magnetic resonance imaging (MRI a suspect diagnosis of meningioma was made. The patient underwent surgery where a soft mass with transverse sinus invasion was encountered; the tumour was successfully resected employing microsurgical techniques. Histological examination revealed a thyroid follicular neoplasm with positive staining for follicular carcinoma in immunohistochemical analysis. Postoperatively levels of thyroid hormones were normal. Treatment was planned for the thyroid gland, patient receiving 6 courses of chemotherapy including paclitaxel. Conclusions: The present case emphasizes that although they are uncommon, dural metastasis can be mistaken for meningiomas. The definitive diagnosis of a meningioma should be established only after the histopathological analysis. Thyroid follicular carcinoma should be included in the differential diagnosis in cases of extrinsic tumoral lesions.

    Full Text Available Thyroid associated orbitopathy, also known as Graves′ orbitopathy, is typically a self-limiting autoimmune process associated with dysthyroid states. The clinical presentation may vary from very mild disease to severe irreversible sight-threatening complications. Despite ongoing basic science and clinical research, the pathogenesis and highly effective therapeutic strategies remain elusive. The present article reviews the pathophysiology, clinical presentation, and management of this common, yet poorly understood disease, which remains a challenge to the ophthalmologist.

    Several recent advances in our knowledge of thyroid physiology have broad application to the diagnosis and management of thyroid disorders. For in the thyroid, more than other end-ocrine organs, pathophysiology can be translated directly into the diagnosis and management of thyroid disease. Graves' disease is a syndrome including goiter with hyperthyroidism, exophthalmos and dermatopathy. The pathogenesis of Graves' disease is not yet clearly identified, but various autoantibodies to the thyroid gland and immunapathalogic studied indicate that autoimmune processes are involved in the pathogenesis of the disease. The diagnosis and management of Graves' disease are largely dependent on radionuclide technique as radioimmunoassay, radioactive iodine therapy and so on. Several laboratory tests are also developed to determine the remission of this disease including TRH stimulation test, T{sub 3}, suppression test and detection of thyroid stimulating immunoglobulins. Autoimmune thyroiditis is almost certainly a primary immunologic disease and the incidence tends to increase recently, mainly due to the application of biopsy technique is thyroid diseases. Thyroid nodules have been a great challenge to physicians because of the possibility of malignancy. But recently, cytologic examination of thyroid aspirate provides a very simple and also reliable diagnostic method in patients with thyroid nodules. In 163 patients with thyroid nodules, only 19.3% was revealed to be malignant. Therefore cytologic examination of thyroid aspirate and thyroid biopsy should be included in the diagnosis of nodular patients prior to surgical intervention. In this paper, a comprehensive review is presented on the pathogenesis, clinical features, laboratory findings and therapeutic modalities of various thyroid diseases on the basis of over 80 researches performed during the past 20 years at radioisotope clinic, Seoul National University Hospital.

    We present a patient with a complex clinical picture of primary hyperparathyroidism with multiple destructive skeletal lesions suspicious of bone metastases and concomitant multifocal papillary thyroid carcinoma with a metastatic central lymph node. He presented with progressively worsening right hip pain and restricted motion. Magnetic resonance imaging revealed multiple lytic lesions involving predominantly the right trochanter minor and the left inferior and posterior pubic rami. Biochemical tests were consistent with primary hyperparathyroidism. Neck ultrasound and parathyroid scintigraphy revealed a single parathyroid adenoma and a thyroid nodule, preoperative cytology of which confirmed papillary thyroid carcinoma, as did the final surgical specimen. Biochemical results, regarding hyperparathyroidism, declined to normal levels and his complaints gradually decreased after surgery. Postoperative whole body bone scintigraphy showed increased tracer uptakes at multiple sites, but they were proved to be metabolically inactive by fluorodeoxyglucose positron emission tomography/computed tomography.

    Full Text Available A 44-year-old female presented with a two-month history of a neck mass, sore throat, hoarseness, and intermittent dysphagia. Examination revealed a “woody” hard swelling arising from the right lobe of the thyroid. Clinically this was felt to be classical Riedel’s thyroiditis (RT. Thyroid ultrasound showed a diffusely enlarged, low echogenicity thyroid with a multinodular goitre. An abnormal nodule extending across the isthmus was noted. Following a nondiagnostic fine needle aspiration, an open core biopsy was performed. This showed dense sclerotic fibrosis punctuated by nodular mononuclear inflammatory cells, which obscured follicular epithelial cells consistent with a fibrosing thyroiditis (Riedel’s thyroiditis. A biopsy of pretracheal lymph nodes showed a sclerotic process throughout the lymph nodes and nests of epithelium bands with squamous differentiation obscured by a fibrous process. These findings raised the differential diagnosis of diffuse sclerosing variant of papillary thyroid carcinoma (DSV-PTC with metastasis to lymph nodes. A total thyroidectomy and pretracheal lymph node dissection were performed. The final histological diagnosis was DSV-PTC. When managing a patient with presumed RT it is important to consider malignancy in the differential. DSV-PTC is one of the more aggressive forms of thyroid cancer but with early diagnosis and appropriate treatment patients may have excellent outcomes.

    Full Text Available This paper looks at the environmental role of vitamin D and solar radiation as risk reduction factors in autoimmune disease. Five diseases are considered: multiple sclerosis, type 1 diabetes, rheumatoid arthritis, autoimmune disease of the thyroid, and inflammatory bowel disease. Clinical relevant studies and factors that may indicate evidence that autoimmune disease is a vitamin D-sensitive disease are presented. Studies that have resulted in prevention or amelioration of some autoimmune disease are discussed. An example of the utility of supplementing vitamin D in an unusual autoimmune disease, idiopathic thrombocytic purpura, is presented.

    Autoimmune hepatitis (AIH) is a disease of unknown etiology, its hallmark being ongoing hepatic inflamma-tion. By its very nature, it is a chronic condition, al-though increasingly, we are becoming aware of patients with acute presentations, some of whom may have liver failure. There are very limited published data on patients with AIH with liver failure at initial diagnosis, which consist mostly of small retrospective studies. As a consequence, the clinical features and optimal management of this cohort remain poorly defined. A subset of patients with AIH who present with liver failure do respond to corticosteroids, but for the vast majority, an urgent liver transplantation may offer the only hope of long-term survival. At present, there is uncertainty on how best to stratify such a cohort into responders and non-responders to corticosteroids as soon as possible after hospitalization, thus optimizing their management. This editorial attempts to answer some of the unre-solved issues relating to management of patients with AIH with liver failure at initial presentation. However, it must be emphasized that, at present, this editorial is based mostly on small retrospective studies, and it is an understatement that multicenter prospective studies are urgently needed to address this important clinical issue.

    Autoimmune thyroid diseases (AITD), which include Hashimoto thyroiditis (HT), Graves' disease (GD) and primary idiopathic myxoedema (PIM), are recognized by their clinical and genetic heterogeneity. In this study, we have carried on a global approach gathering 20 year genetic and clinical data on a Tunisian multigenerational family (Akr). Our purpose was search for a combined genotype involved in AITD susceptibility using 33 gene polymorphisms. The Akr pedigree is composed of more than 400 members distributed on 10 generations. Clinical follow-up was performed by appreciation of the thyroid gland and measurement of both thyroid hormone and auto antibody levels. We used FBAT software to test for association between gene polymorphisms and AITDs. Clinical follow-up has showed that the number of AITD patients has increased from 25 to 78 subjects subdivided on 51 cases of GD, 22 PIM and 5 HT. Concerning genetic analysis, our study has revealed new gene association when compared with our previous analysis (considering single genes). Thus, PTPN22, TG and VDR gene polymorphisms have became associated with p-values ranging from 4.6  10− 2 to 4  10− 3 when considered with other genes on the same chromosome; giving evidence for gene interaction. The most significant association was found with the MHC region (p = 7.15 10− 4). Moreover, and among gene polymorphisms explored, our analysis has identified some of them as AITD biomarkers. Indeed, PDS gene polymorphisms were associated with either exophthalmia or goiter (p-values from 10− 2 to 10− 3). In conclusion, our study gives evidence for gene interaction in AITD development confirming genetic complexity of these diseases. PMID:25606390

    Objective. Marine-Lenhart Syndrome (MLS) is defined as concomitant occurrence of autonomously functioning thyroid nodule (AFTN) with Graves' disease (GD). Malignancy in a functional nodule is rare. We aimed to present an extremely rare case of papillary thyroid cancer in a MLS nodule with lateral lymph node metastases. Case. A 43-year-old male presented with hyperthyroidism and Graves' ophthalmopathy. On Tc99m pertechnetate scintigraphy, a hyperactive nodule in the left upper thyroid pole was detected and the remaining tissue showed a mildly increased uptake. The ultrasonography demonstrated 15.5 × 13.5 × 12 mm sized hypoechoic nodule in the left upper pole of the thyroid and round lymph nodes on the left side of the neck. Fine needle aspiration biopsy (FNAB) of the nodule and lymph node revealed cytological findings consistent with papillary cancer. Total thyroidectomy with central and left modified radical neck dissection was performed. On pathologic examination, two foci of micropapillary cancer were detected. The skip metastases were present in three lymph nodes on the neck. Conclusion. AFTN can be seen rarely in association with GD. It is not possible to exclude malignancy due to the clinical and imaging findings. In the presence of suspicious clinical and sonographic features, FNAB should be performed. PMID:27110424

    Background Turner syndrome is caused by numeric and structural abnormalities of the X chromosome. An increased frequency of autoimmunity as well as an elevated incidence of autoantibodies was observed in Turner patients. The aim of this study was to conduct a retrospective analysis of the incidence of autoimmunity in 66 Italian patients affected by Turner syndrome. Methods Sixty-six unselected and consecutive Italian Turner patients were recruited. The association between age, karyotype and the presence of clinical/pre-clinical autoimmune disorders and of autoantibodies was examined. Results Out of the 66 Turner patients, 26 had thyroid autoimmune disorders (39.4%), 14 patients had Hashimoto’s thyroiditis with clinical or subclinical hypothyroidism (21.2%) and 12 patients had circulating anti-thyroid antibodies, echographic pattern of diffuse hypoechogenicity and normal thyroid hormone levels (18.2%). None were affected by Graves’ disease. We analyzed the overall incidence of thyroid autoimmunity within the 3 different age groups 0–9.9, 10–19.9 and 20–29.9 years. No statistically significant difference was observed in the incidence of thyroid autoimmunity within the age-groups (χ2-test p > 0.05). Out of the 66 patients, 31 patients had the 45,X karyotype; within this first group 14 out of 31 patients were affected by autoimmune thyroid disease. A second group of 29 patients included 19 patients with mosaicism, 5 patients with deletions and 5 patients with ring chromosome; out of these 29 patients 7 were affected by autoimmune thyroid disease. A third group included 6 patients with X isochromosome; 5 out of 6 were affected by autoimmune thyroid disease. A statistically significant difference in the frequency of thyroid autoimmunity within the different karyotype groups was observed (χ2-test p = 0.0173). When comparing the X isochromosome group with the pooled group of other karyotypes, of note, the frequency of thyroid autoimmunity was

In some cases, it is presented as hyperthyroidism because of Graves’ disease. Thyroid function and thyroid antibodies should be evaluated before and during treatment with interferon.

  4. Thyroid hormone antibodies and Hashimoto's thyroiditis in mongrel dogs

    International Nuclear Information System (INIS)

    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 125I-labeled thyroid hormones demonstrated binding of [125I]T4 to transthyretin, thyroid hormone-binding globulin, and albumin and of [125I]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

    Autoimmune manifestations (AIM) are reported in up to 10-30% of myelodysplastic syndromes (MDS) patients; this association is not well defined. We present herein a retrospective chart review of single center MDS patients for AIM, a case discussion and a literature review. Of 252 MDS patients examined, 11 (4.4%) had AIM around MDS diagnosis. International Prognostic Scoring System scores were: low or intermediate (int)-1 (n=7); int-2 or high (n=4). AIM were: culture negative sepsis (n=7); inflammatory arthritis (n=3); vasculitis (n=4); sweats; pericarditis; polymyalgia rheumatica (n=2 each); mouth ulcers; pulmonary infiltrates; suspicion for Behcet's; polychondritis and undifferentiated (n=1 each). AIM treatment and outcome were: prednisone +/- steroid sparing agents, n=8, ongoing symptoms in 5; azacitidine (n=3), 2 resolved; and observation, n=1, ongoing symptoms. At a median follow up of 13 months, seven patients are alive. In summary, 4.4% of MDS patients presented with concomitant AIM. MDS should remain on the differential diagnosis of patients with inflammatory symptoms. PMID:27499837

    Autoimmune autonomic ganglionopathy (AAG) is an acquired immune-mediated disorder that leads to systemic autonomic failure. Autoantibodies to the ganglionic nicotinic acetylcholine receptor (gAChR) are detected in 50% of AAG patients. We report the first pediatric case of AAG presenting with acute encephalitis. The patient was a 13-year-old boy who presented with orthostatic hypotension, followed by rapidly progressing disturbance of consciousness. Cerebrospinal fluid analysis revealed significant pleocytosis and increased neopterin concentration. Head MRI showed hyperintensities in bilateral caudate nuclei, putamen, hippocampus, and insula cortex. Severe autonomic dysfunctions such as severe orthostatic hypotension, bradycardia, dysuria, prolonged constipation and vomiting appeared. These symptoms were successfully controlled by repeated immunomodulating therapy with intravenous methylprednisolone pulse therapy and intravenous immunoglobulin. Autoantibodies to the α3 subunit of gAChR were detected at neurological onset, but were undetectable five months later. This observation indicates that AAG should be suspected in patients manifesting acute encephalitis characterized by preceding and prolonged autonomic symptoms, and immunomodulating therapy from an early stage can be effective.

    Brucellosis is a zoonotic infectious disease that can be transmitted to humans through infected milk and dairy products. There are limited cases with Brucella infection acquired via breastfeeding in infants in the literature. Also, Coombs-positive autoimmune hemolytic anemia as a result of the disease is comparatively rare when considering the other frequent hematologic complications. We report a mother who acquired the infection as a result of consuming infected milk and dairy products after delivery and of her 5-month-old baby, who had acquired the disease via breastfeeding and presented with Coombs-positive autoimmune hemolytic anemia.

    In early onset autoimmune thyroid disease (AITD) showing a strong genetic tendency, cytokines have been suggested to play a critical role in the development of AITD. To directly compare the influences of several cytokine gene polymorphisms, 25 single nucleotide polymorphisms (SNPs) in 17 cytokine genes were analyzed on 104 Korean children with AITD [Hashimoto's disease (HD) = 44, Graves' disease (GD) = 60 (thyroid-associated ophthalmopathy (TAO) = 29, non-TAO = 31)] and 192 controls. Compared with healthy controls, any significant association with polymorphisms of cytokine genes was not found in HD and GD. Among GD patients, non-TAO group only showed significant associations with IL-12 C allele (rs3212227: A > C) (76.6% vs. 51.6%, OR = 0.3 [0.15-0.71], Pc = 0.007). Particularly, the frequency of IL-12C allele was significantly lower in the non-TAO group than in the TAO group (82.8% vs. 51.6%, Pc = 0.018). Our comprehensive analysis of cytokine gene polymorphisms suggests that IL-12 gene may play impact on specific pathogenesis of ophthalmopathy in Korean children with AITD. PMID:26850223

    We describe a case of a 31-year-old man who presented with a 3-day history of crampy abdominal pain, anorexia, malaise and diarrhoea of increasing frequency, with the passage of both mucus and haematochezia. The patient's biochemical investigations revealed hyponatraemia, hypothyroidism and elevated inflammatory markers. The patient underwent an ultrasound and fine-needle aspiration of the thyroid and was diagnosed as having Hashimoto's thyroiditis. He was started on thyroxine and fluid was restricted. He was also investigated for alternative causes of hyponatraemia. With improvement in his hyponatraemia, the patient underwent a colonoscopy with biopsies confirming a concurrent diagnosis of ulcerative colitis. He was started on mesalazine and prednisolone and discharged from hospital. He suffered a flare shortly after discharge and was readmitted to hospital. He was again discharged, on a higher dose of prednisolone, with outpatient follow-up at our hospital's gastroenterology clinic. PMID:27107058

Incluyen varias formas clínicas como Tiroiditis de Hashimoto (TH y Enfermedad de Graves (EG. La relación entre TH y EG ha sido objeto de debate por décadas. Si bien, muy diferentes en su clínica, algunos las consideran los lados opuestos de una misma moneda. En su patogénesis tienen aspectos en común, como la predisposición genética demostrado por la ocurrencia en una misma familia y en un mismo individuo. Sin embargo, diferencias en el microambiente local determinan la diferente expresión fenotípica o el viraje de una a otra patología. El objetivo de esta monografía es investigar similitudes y diferencias entre TH y EG en las distintas etapas que llevan al desarrollo de autoinmunidad. Los autores declaran no poseer conflictos de interés.Autoimmune thyroid disease (ATD is the most common disorder that leads to thyroid gland dysfunction. ATD manifests in various clinical forms, such as Hashimoto's Thyroiditis (HT and Graves' Disease (GD. The relation between HT and GD has been discussed for decades. Even if they greatly differ in their clinical features and treatment, some people believe they are the opposite sides of the same coin. In their pathogenesis, they share some mechanisms, such as genetic susceptibility, shown by the fact that they tend to occur both in the same person and within the same family. However, differences in the local micro-environment can determine the distinct phenotypic expression or the switch from one disease to the other. The aim of this monograph was to investigate similarities and differences between HT and GD at the diverse stages leading to the development of autoimmunity. No financial conflicts of interest exist.

These findings would suggest that 6% of the ME/CFS patients seen, or 6,000 cases per 100,000, had a confirmed thyroid malignancy. Unfortunately, these figures may be conservative since we are in the process of obtaining needle biopsies on six further cases of these first 100 patients. In addition, we have not yet performed thyroid ultrasound on all 100 cases. We are in the process of further investigation of those patients who had not yet been investigated by thyroid ultrasound. Previously, it has been noted that the increased incidence of thyroid malignancy in the general population is only associated with increased radiation exposure. Patients presenting with symptoms of ME/CFS or Fibromyalgia may have significant higher thyroid malignancy incidence.

    Thyroid peroxidase (TPO) is a key enzyme in the synthesis of thyroid hormone. TPO is involved in thyroid hormone synthesis (organification and coupling reactions). TPO is a major antigen corresponding to thyroid-microsomal autoantibodies. Anti-TPO auto antibodies are very important to diagnose autoimmune thyroid diseases and also in estimating its clinical course. Autoimmune thyroid disease is detected mostly by measuring circulating antibodies to thyroglobulin which is uncommon measurement o...

    Abstract Background: The first cases of pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) were described>15 years ago. Since that time, the literature has been divided between studies that successfully demonstrate an etiologic relationship between Group A streptococcal (GAS) infections and childhood-onset obsessive-compulsive disorder (OCD), and those that fail to find an association. One possible explanation for the conflicting reports is that the diagnostic criteria proposed for PANDAS are not specific enough to describe a unique and homogeneous cohort of patients. To evaluate the validity of the PANDAS criteria, we compared clinical characteristics of PANDAS patients identified in two community practices with a sample of children meeting full research criteria for PANDAS. Methods: A systematic review of clinical records was used to identify the presence or absence of selected symptoms in children evaluated for PANDAS by physicians in Hinsdale, Illinois (n=52) and Bethesda, Maryland (n=40). Results were compared against data from participants in National Institute of Mental Health (NIMH) research investigations of PANDAS (n=48). Results: As described in the original PANDAS cohort, males outnumbered females (95:45) by ∼ 2:1, and symptoms began in early childhood (7.3±2.7 years). Clinical presentations were remarkably similar across sites, with all children reporting acute onset of OCD symptoms and multiple comorbidities, including separation anxiety (86–92%), school issues (75–81%), sleep disruptions (71%), tics (60–65%), urinary symptoms (42–81%), and others. Twenty of the community cases (22%) failed to meet PANDAS criteria because of an absence of documentation of GAS infections. Conclusions: The diagnostic criteria for PANDAS can be used by clinicians to accurately identify patients with common clinical features and shared etiology of symptoms. Although difficulties in documenting an association

    A 38-year-old woman presented with erythematous, violaceous plaques with a serpiginous and unusual appearance located on the left shoulder, left thigh, and right buttock, evolving for 5 days, which eventually became generalized. A skin biopsy revealed leukocytoclastic vasculitis and a diagnosis of urticarial vasculitis was made. The complete blood count, biochemistry, complement levels, and other immunological test results were unremarkable. However, antithyroid antibody titers were increased. Despite having normal thyroid function tests and an absence of specific symptoms, the patient underwent a thyroid ultrasound, which revealed features of thyroiditis, and was subsequently referred to an endocrinologist. Several diseases can be associated with urticarial vasculitis, namely infections and autoimmune connective-tissue disorders such as systemic lupus erythematosus and Sjögren syndrome. Thyroiditis is an uncommon association. PMID:23000939

    Full Text Available Introduction. Hashimoto's thyroiditis is a common form of chronic autoimmune thyroid disease (AITD and often coexists with other autoimmune diseases, but Hashimoto’s thyroiditis associated with an autosomal dominant neurofibromatosis type 1 is exceedingly rare. Case Presentation. A 30-year-old Bengali woman presented to the OPD with complaints of aching pain and tingling sensation in her hands and feet. Physical examination revealed dysmorphic facies, nodular swelling in the neck, cafe-au-lait spots, and neurofibromas covering the entire surface of her body. Her thyroid hormones were within normal limits. Thyroid ultrasound revealed a cystic area in the left lobe of the gland, and ultrasound-guided fine needle aspiration cytology revealed lymphocytic infiltration of the gland, suggesting Hashimoto’s thyroiditis. High levels of autoimmune antibodies such as antithyroglobulin and antimicrosomal antibodies confirmed the diagnosis. Conclusion. When encountered with a patient of Neurofibromatosis type 1, a physician should be careful about the possibility of a concomitant autoimmune disease. Clinical presentation of neurofibromatosis and Noonan syndrome often overlaps and recent studies have implicated a mutation in NF1 gene in the etiology of NFNS. More extensive reports and further investigations of such patients having combination of neurofibromatosis type 1 and autoimmune thyroiditis will certainly provide better understanding of this link in the near future.

    Autoimmune thyroid disease (AITD), including Graves disease (GD) and Hashimoto disease (HD), is an organ-specific autoimmune disease with a strong genetic component. Although the cytotoxic T-lymphocyte-associated protein 4 (CTLA4) polymorphism has been reported to be associated with AITD in adults, few studies have focused on children. The aim of our study was to investigate whether the CTLA4 polymorphisms, including -318C/T (rs5742909), +49A/G (rs231775), and CT60 (rs3087243), were associated with GD and HD in Han Chinese adults and children. We studied 289 adult GD, 265 pediatric GD, 229 pediatric HD patients, and 1058 healthy controls and then compared genotype, allele, carrier, and haplotype frequencies between patients and controls. We found that CTLA4 SNPs +49A/G and CT60 were associated with GD in adults and children. Allele G of +49A/G was significantly associated with GD in adults (odds ratio [OR], 1.50; 95% confidence interval [CI], 1.21–1.84; corrected P value [Pc] < 0.001) and children (OR, 1.42; 95% CI, 1.15–1.77; Pc = 0.002). Allele G of CT60 also significantly increased risk of GD in adults (OR, 1.63; 95% CI, 1.27–2.09; Pc < 0.001) and GD in children (OR, 1.58; 95% CI, 1.22–2.04; Pc < 0.001). Significant linkage disequilibrium was found between +49A/G and CT60 in GD and control subjects (D’ = 0.92). Our results showed that CTLA4 was associated with both GD and HD and played an equivalent role in both adult and pediatric GD in Han Chinese population. PMID:27111218

  4. Bone metastases from initially unknown origin as unusual presentation of thyroid cancer

    International Nuclear Information System (INIS)

    The insular carcinoma of thyroid gland is a poorly frequent neoplasm, slightly differentiated and of clinical aggressive course. The bone metastasis unique as a form of presentation in absence of regional ganglions compromise or another metastasis localization is very unusual. The local invasion, regional ganglions and metastases at a distance (lung and bone) are the usual conduct. It is of interesting to highlight the importance of the immunoreactivity for Tg (thyroglobulin) to tackle the diagnosis, like also the considerable absorption with Tc99m-MDP, I131 and Tc99m-MIBI by the tissue of the metastasis

    2014-10-01

    Full Text Available Hashimoto’s thyroiditis, the most common autoimmune thyroid disease, is due to destruction of the thyroid gland by autoantibodies. Various types of thyroid malignancies may arise in Hashimoto’s thyroiditis. Follicular carcinomas, papillary carcinomas, lymphomas, medullary carcinomas and hurthle cell neoplasms may develop in Hashimoto’s thyroiditis. We present a rare case report of a 35-year-old female who presented with hypothyroidism of a two-year duration. A diagnosis of Hashimoto’s thyroiditis was made for which she was under treatment. Due to the recent increase in size of the thyroid, a fine needle aspiration cytology was done. A preoperative diagnosis of Hurthle cell neoplasm was made based on fine needle aspiration cytology findings. The total thyroidectomy specimen revealed Hashimoto’s thyroiditis with synchronous papillary carcinoma and Hurthle cell carcinoma, which is a very rare occurrence.

    Vitiligo is a chronic disease characterized by the dysfunction or destruction of melanocytes with secondary depigmentation. The aim of the present study was to determine the prevalence of vitiligo associated with autoimmune rheumatic diseases. The clinical records from a 10-year database of patients with rheumatic diseases and associated vitiligo was analysed, with one group of patients having autoimmune rheumatic disease and another non-autoimmune rheumatic disease. Available serum samples were used to assess the anti-melanocyte antibodies. A total of 5,251 individual clinical files were archived in the last 10 years, and these patients underwent multiple rheumatology consultations, with 0.3% of the group presenting with vitiligo. The prevalence of vitiligo in the autoimmune rheumatic disease group was 0.672%, which was mainly associated with lupus and arthritis. However, patients with more than one autoimmune disease had an increased relative risk to develop vitiligo, and anti-melanocyte antibodies were positive in 92% of these patients. By contrast, the prevalence was 0.082% in the group that lacked autoimmune rheumatic disease and had negative autoantibodies. In conclusion, the association between vitiligo and autoimmune rheumatic diseases was relatively low. However, the relative risk increased when there were other autoimmune comorbidities, such as thyroiditis or celiac disease. Therefore, the presence of multiple autoimmune syndromes should be suspected. PMID:27446537

Case report We report an 81-yearold man with AIP associated with IPMN. Although the initial pancreatogram was normal, a short narrowing of the main pancreatic duct (MPD appeared during a follow-up for IPMN after 6 months, which was highly suggestive of pancreatic cancer. A narrowing of the MPD extended after 15 months, and this progressed to diffuse narrowing of the MPD with an elevation in the serum IgG4 levels after 24 months. Finally, the patient was diagnosed with diffuse-type AIP, according to the Japanese diagnostic criteria 2011 and the International Consensus Diagnostic Criteria. Considering the natural history of AIP, this marked change of the MPD is indicative of this condition. Conclusion Wereport a case of AIP presenting with a short narrowing of the MPD with subsequent progression to diffuse pancreatic enlargement during a follow-up for IPMN.

    Full Text Available Hashimoto′s thyroiditis (HT, an autoimmune disorder, is the most prevalent cause of subclinical or overt hypothyroidism in areas with sufficient iodine intake. The gland is often diffusely enlarged, and the parenchyma is coarsened, hypoechoic, and often hypervascular on ultrasonograpy. Histopathologic appearance of HT includes lymphocyte aggregates with germinal centers, small thyroid follicles, presence of Hurthle cells, and variable fibrosis. We present a case of a 40-year-old female with suspected follicular neoplasm on fine-needle aspiration cytology of neck swelling. Intraoperatively, thyroid gland was found having four lobes separated from each other. Total thyroidectomy was done and histopathology from all four lobes revealed HT. At present, there is no literature to support the fact that such distorted thyroid anatomy may be due to the underlying disease. If we consider it as thyroid gland anomaly, no such anomaly has been mentioned in the literature till date.

    Thyroid surgeons are becoming increasingly more aware of a histologically distinct subset of thyroid carcinoma whose classification falls between well-differentiated and anaplastic carcinomas with respect to both cell differentiation and clinical behavior. This subtype of tumors has been categorized as poorly differentiated or insular carcinoma, based on its characteristic cell groupings. Although the differentiation of insular carcinoma from other thyroid carcinomas has important prognostic ...

    Most medullary thyroid carcinomas show suspicious malignant features such as hypoechogenicity, a spiculated margin and/or intranodular calcifications, which are well known features of papillary carcinoma. We report here on a case of medullary carcinoma that was seen as a predominantly cystic thyroid mass on ultrasonography. This type of case is not common in the literature and we discuss the way to diagnose a medullary thyroid carcinoma

  12. Screening for thyroid cancer in children

    International Nuclear Information System (INIS)

    In the screening of the thyroid diseases in the radiation exposed cohort, it is essential to make correct diagnosis and to measure radiation dose in every subjects in the cohort and to analyze the dose response relationship by the most appropriate statistical method. Thus, thyroid cancer, thyroid adenoma and autoimmune hypothyroidism were confirmed to be radiation-induced thyroid diseases among atomic bomb survivors. A group of investigators from Nagasaki university have been working in the thyroid part of Chernobyl Sasakawa Health and Medical Cooperation Project, and more than 80000 children were screened in 5 diagnostic centers (Mogilev, Gomel, Kiev, Korosten and Klincy). In order to make correct diagnosis, thyroid echo-tomography, measurements of serum levels of free thyroxine, TSH, titers of anti-thyroid antibodies were performed in every children in the cohort and aspiration biopsy was performed when necessary. Whole body Cs137 radioactivity was also determined in every subjects. Children with thyroid cancer confirmed by histology (biopsy or operation) were 2 in Mogilev, 19 in Gomel, 6 in Kiev, 5 in Korosten and 4 in Klincy (until 1994). Since children screened in each center were less than 20000, prevalence of thyroid cancer was remarkably high (lowest 100 and highest 1000/million children) when compared to the other parts of the world (0.2 to 5/million/year). However, there was no dose response relationship between the prevalence of cancer or nodule and whole body Cs137 radioactivity. Although a significant correlation between thyroid cancer and reconstructed thyroid I131 dose was presented, there are no previous reports to prove that I131 produces thyroid cancer in human. Investigation on external radiation and short lived isotopes along with I131 may be important to elucidate the cause of thyroid cancer

    International Nuclear Information System (INIS)

    The role of ionizing radiation in the introduction of thyroid carcinoma is discussed. In the treatment of thyroid cancer, radioiodine administration is of value as an ablation procedure, completing the thyroidectomy and as a method to irradiate selectively functioning thyroid carcinoma tissue that cannnot be removed surgically. Results of the clinical management of 155 patients with malignant thyroid tumours are presented. The ablation dose of iodine-131 can be decreased to 40 millicuries thus effectively reducing the patients whole body radiation dose

    Full Text Available Autoimmune hemolytic anemia is uncommon. The estimated overall (not age-adjusted annual incidence is about 1 case per 100,000 populations; after age 60 years, the annual incidence reaches 10 per 100,000. The disorder can occur at any age, but most patients are older than 40 years. About 65% of patients with primary autoimmune hemolytic anemia are women, and almost all cases that complicate systemic lupus erythematosus occur in women. A 65 years old male presented with generalized weakness, breathlessness on exertion, swelling of lower limbs and pain abdomen of 6 months duration. He was previously admitted elsewhere on several occasions (within past 3-4 months with similar complaints, and had received multiple blood transfusions. On clinical examination, patient had pallor and bilateral pitting pedal edema. Abdominal examination revealed massive Splenomegaly (12 cm below left costal margin, moderate Hepatomegaly. Investigations revealed Hb% of 8.6 g/dl, Platelet count = 1 lakh/cmm, ESR = 120 mm, retic count -2.2 %. Peripheral smear showed evidence of hemolysis. Serum LDH was high, Serum bilirubin predominantly indirect hemoglobin= 2, S. Haptoglobin below 6.63. These findings suggested hemolysis as a cause of his anemia and splenomegaly. Further evaluation was done to find out the cause of hemolysis in this elderly male. Hb Quantification using HPLC was normal. Serum G6PD activity was normal. ANA was negative. Hams test was negative. Direct & Indirect Coomb’s tests were positive. Bone marrow examination showed erythroid hyperplasia. CT Abdomen showed hepatosplenomegaly. Upper GI endoscopy and colonoscopy were normal. Based on these findings a diagnosis of warm antibody type auto immune haemolytic anaemia (AIHA, probably of idiopathic type, was made and patient was started on steroid therapy. After 2 weeks, repeat haemoglobin was 12.8 gm%, WBC count was 7020/cumm reflecting response to steroid therapy. Severe AIHA can be a medical emergency. Red

    Full Text Available Abstract Background Although the interactions between lithium treatment and thyroid function have long been recognised, their clinical relevance is still controversial. This paper sets out a review of the literature to date, considering that lithium still represents the gold standard among prophylactic treatments of manic-depression several decades after its introduction. Method PubMed database was used to search for English-language articles relating to lithium treatment and thyroid function. As the amount of relevant papers totalled several hundreds, this review refers to previous reviews, especially with regard to older literature. Moreover, the authors particularly refer to a series of studies of thyroid function performed in a cohort of patients at different stages of lithium treatment, who were followed up by their group from 1989 onwards. Results The main findings from this review included: a lithium definitely affects thyroid function as repeatedly shown by studies on cell cultures, experimental animals, volunteers, and patients; b inhibition of thyroid hormone release is the critical mechanism in the development of hypothyroidism, goitre, and, perhaps, changes in the texture of the gland which are detected by ultrasonic scanning; c compensatory mechanisms operate and prevent the development of hypothyroidism in the majority of patients; d when additional risk factors are present, either environmental (such as iodine deficiency or intrinsic (immunogenetic background, compensatory potential may be reduced and clinically relevant consequences may derive; e hypothyroidism may develop in particular during the first years of lithium treatment, in middle-aged women, and in the presence of thyroid autoimmunity; f thyroid autoimmunity is found in excess among patients suffering from affective disorders, irrespective of lithium exposure; g in patients who have been on lithium for several years, the outcome of hypothyroidism, goitre, and thyroid

The autoimmune polyglandular syndrome type 2 is defined by the presence of at least two of the following diseases: Addison’s disease, type 1 diabetes mellitus and thyroid autoimmune disease. Other autoimmune diseases belonging to the autoimmune polyglandular syndrome type 2 are: primary hypogonadism, myast...

  1. Evaluation of the 2. generation radio-receptional assay for anti-TSH receptor antibodies (TRAb) in autoimmune thyroid diseases. Comparison with 1. generation and anti-thyroperoxidae antibodies (AbTPO)

    International Nuclear Information System (INIS)

    The detection of autoantibodies to the TSH-receptor (TRAb) by radio-receptor assays (RRA) is widely requested in clinical practice for the diagnostic work-up of Graves' disease and its differentiation from diffuse thyroid autonomy. Additionally, TRAb measurement can be useful during antithyroid drug treatment of Graves' disease to evaluate the risk of relapse after therapy discontinuation. Nevertheless, some patients affected by Graves' disease are TRAb-negative when 1. generation assay is used. In this study the diagnostic performance of a newly developed 2. generation TRAb assay (TRAK human DYNOtest(R), BRAHMS Diagnostica GmbH, Berlin, Germany) was evaluated in 74 untreated patients affected by Graves' disease, in 53 untreated patients affected by Hashimoto's thyroiditis and in 88 patients affected by euthyroid nodular goiter. It was also compared the new TRAb assay with the 1. generation test (TRAK(R) Assay, BRAHMS Diagnostica GmbH, Berlin, Germany) and anti-thyroperoxidase assay (AbTPO DYNOtest(R), BRAHMS GmbH, Berlin). The 2. generation TRAb assay showed the better diagnostic sensitivity in Graves' disease (97%) with respect to the 1. generation assay (85%) and AbTPO assay (64%). The AbTPO assay was positive in 50 of 53 (94%) patients affected by autoimmune thyroiditis. The 1. and 2. generation TRAb assays were positive in 4 (7%) and 7 (13%) of 53 patients affected by autoimmune thyroiditis, respectively. No patients affected by nodular goiter showed positive 1. and 2. generation TRAb assay while AbTPO levels were positive in 8 of 88 patients (specificity 91%). In conclusion, the 2. generation TRAb assay is clearly more sensitive than the 1. generation test and should be used in clinical practice to minimize the incidence of TRAb-negative Graves' disease. Long term prospective studies are needed to evaluate the prognostic role of 2. generation TRAb assay in Graves' disease. The assay of AbTPO is the best marker for autoimmune thyroiditis but is clearly less

    Most systemic autoimmune diseases occur more frequently in females than in males. This is particularly evident in Sjögren’s Syndrome, Systemic Lupus Erythromatosis (SLE) and thyroid autoimmunity, where the ratio of females to males ranges from 20:1 to 8:1. Our understanding of the etiology of SLE implies important roles for genetics, environmental factors and sex hormones, but the relative significance of each remains unknown. Using the New Zealand hybrid mouse model system of SLE we present ...

    We aimed to evaluate the clinical and pathologic features of two common medical illnesses and their appropriate workup and pathognomonic findings. A 57-year-old white male presented with a new onset expressive aphasia while traveling abroad. He was evaluated at an outside facility and underwent workup for a stroke. The evaluation included a CT and MRI of the brain demonstrating three new enhancing lesions, the largest of which was a 2.5 cm ring-enhancing cystic lesion. A CT of the chest noted a 4-cm cystic thyroid lesion that was diagnosed as a thyroid cancer with brain metastases. The patient was told that he had cancer and needed therapy. The patient elected to be treated closer to home and presented to our institution with a referral for brain irradiation. The patient was evaluated and his case was reviewed in a neuro/oncology tumor board, where several other possible diagnoses were considered. A complete workup was performed, including two separate FNAs of the thyroid mass along with a PET scan, CEA test, CBC test, CMP, CRP, sed rate, and SLE testing, along with a spinal tap (cytology, protein, and serology). The MRI on further review showed that one of the lesions was a periventricular enhancing area and the largest lesion was an open ring with T2 and DWI enhancement. The fine needle aspiration (FNA) samples of the thyroid both showed benign histology. The laboratory evaluation was negative except for a mildly elevated CRP with no tumor markers identified and the spinal tap was positive for elevated protein and particularly oligoclonal bands. The PET scan showed no sites of fluorodeoxyglucose (FDG) avid masses including the thyroid. Multiple sclerosis (MS) represents 400,000 cases in the US and benign thyroid nodules noted on imaging range from 19-35% of the population. One pathognomonic finding of MS that is less common is the open rings called tumefactive lesions versus the closed rings seen with metastases. A cystic thyroid lesion can range from a

    Diabetes mellitus is increasing in prevalence worldwide. The economic costs are considerable given the cardiovascular complications and co-morbidities that it may entail. Type 1 diabetes (T1D) is a chronic autoimmune disease characterized by the loss of insulin-producing pancreatic β-cells. The pathogenesis of T1D is complex and multifactorial and involves a genetic susceptibility that predisposes to abnormal immune responses in the presence of ill-defined environmental insults to the pancreatic islets. Genetic background may affect the risk for autoimmune disease and patients with T1D exhibit an increased risk of other autoimmune disorders such as autoimmune thyroid disease, Addison's disease, autoimmune gastritis, coeliac disease and vitiligo. Approximately 20%-25% of patients with T1D have thyroid antibodies, and up to 50% of such patients progress to clinical autoimmune thyroid disease. Approximately 0.5% of diabetic patients have concomitant Addison's disease and 4% have coeliac disease. The prevalence of autoimmune gastritis and pernicious anemia is 5% to 10% and 2.6% to 4%, respectively. Early detection of antibodies and latent organ-specific dysfunction is advocated to alert physicians to take appropriate action in order to prevent full-blown disease. Patients and family members should be educated to be able to recognize signs and symptoms of underlying disease. PMID:26903475

    Full Text Available Abstract Background It has recently become evident that circulating thyroid antibodies are found in excess among patients suffering from mood disorders. Moreover, a manic episode associated with Hashimoto's thyroiditis has recently been reported as the first case of bipolar disorder due to Hashimoto's encephalopathy. We report a case in which Hashimoto's thyroiditis was suspected to be involved in the deteriorating course of mood disorder and discuss potential pathogenic mechanisms linking thyroid autoimmunity with psychopathology. Case presentation A 43-year-old woman, with a history of recurrent depression since the age of 31, developed manic, psychotic, and soft neurological symptoms across the last three years in concomitance with her first diagnosis of Hashimoto's thyroiditis. The patient underwent a thorough medical and neurological workup. Circulating thyroperoxidase antibodies were highly elevated but thyroid function was adequately maintained with L-thyroxine substitution. EEG was normal and no other signs of current CNS inflammation were evidenced. However, brain magnetic resonance imaging evidenced several non-active lesions in the white matter from both hemispheres, suggestive of a non-specific past vasculitis. Brain single-photon emission computed tomography showed cortical perfusion asymmetry particularly between frontal lobes. Conclusion We hypothesize that abnormalities in cortical perfusion might represent a pathogenic link between thyroid autoimmunity and mood disorders, and that the rare cases of severe Hashimoto's encephalopathy presenting with mood disorder might be only the tip of an iceberg.

    Full Text Available Abstract Background Autoimmune pancreatitis is a rare chronic inflammatory pancreatic disease that is increasingly being diagnosed worldwide. As a result of overlap in clinical and radiological features, it is often misdiagnosed as pancreatic cancer. We report the case of a patient with autoimmune pancreatitis that was initially misdiagnosed as pancreatic cancer. Case presentation A 31-year-old Caucasian man presented to our hospital with epigastric pain, jaundice and weight loss. His CA 19-9 level was elevated, and computed tomography and endoscopic ultrasound revealed a pancreatic head mass abutting the portal vein. Endoscopic retrograde cholangiopancreaticography showed narrowing of the biliary duct and poor visualization of the pancreatic duct. Fine-needle aspiration biopsy revealed atypical ductal epithelial cells, which raised clinical suspicion of adenocarcinoma. Because of the patient's unusual age for the onset of pancreatic cancer and the acuity of his symptoms, he was referred to a tertiary care center for further evaluation. His immunoglobulin G4 antibody level was 365 mg/dL, and repeat computed tomography showed features typical of autoimmune pancreatitis. The patient's symptoms resolved with corticosteroid therapy. Conclusion Autoimmune pancreatitis is a rare disease with an excellent response to corticosteroid therapy. Its unique histological appearance and response to corticosteroid therapy can reduce unnecessary surgical procedures. A thorough evaluation by a multidisciplinary team is important in rendering the diagnosis of autoimmune pancreatitis.

    2016-05-01

    Polyglandular autoimmune syndromes (PGAS), also known as autoimmune polyendocrinopathy syndromes (APS), are a heterogeneous group of rare, genetically caused diseases of the immune system which lead to inflammatory damage of various endocrine glands resulting in malfunctions. In addition, autoimmune diseases of non-endocrine organs may also be found. Early diagnosis of PGAS is often overlooked because of heterogeneous symptoms and the progressive occurrence of the individual diseases. The two most important forms of PGAS are the juvenile and adult types. The juvenile type (PGAS type 1) is caused by mutations in the autoimmune regulator (AIRE) gene on chromosome 21, exhibits geographic variations in incidence and is defined by the combination of mucocutaneous candidiasis, Addison's disease and hypoparathyroidism. In addition, autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) syndrome and other autoimmune diseases can also occur. The adult form of PGAS (PGAS type 2) is a multigenetic disorder associated with some HLA haplotypes, is more common than the juvenile type, shows female predominance and exhibits the combination of type 1 diabetes, autoimmune thyroid disease, Addison's disease and other autoimmune disorders. The histological alterations in affected organs of PGAS patients are similar to findings in sporadically occurring autoimmune diseases of these organs but there are no pathognomic fine tissue findings. If patients exhibit autoimmune changes in two different endocrine glands or if there are indications of several autoimmune disorders from the patient history, it is important to consider PGAS and inform the clinicians of this suspicion.

    2011-01-01

    Full Text Available OBJECTIVE: To characterize thyroid disturbances induced by interferon-alpha and ribavirin therapy in patients with chronic hepatitis C. INTRODUCTION: Interferon-alpha is used to treat chronic hepatitis C infections. This compound commonly induces both autoimmune and non-autoimmune thyroiditis. METHODS: We prospectively selected 26 patients with chronic hepatitis C infections. Clinical examinations, hormonal evaluations, and color-flow Doppler ultrasonography of the thyroid were performed before and during antiviral therapy. RESULTS: Of the patients in our study, 54% had no thyroid disorders associated with the interferon-alpha therapy but showed reduced levels of total T3 along with a decrease in serum alanine aminotransferase. Total T4 levels were also reduced at 3 and 12 months, but free T4 and thyroid stimulating hormone (TSH levels remained stable. A total of 19% of the subjects had autoimmune interferon-induced thyroiditis, which is characterized by an emerge of antithyroid antibodies or overt hypothyroidism. Additionally, 16% had non-autoimmune thyroiditis, which presents as destructive thyroiditis or subclinical hypothyroidism, and 11% remained in a state of euthyroidism despite the prior existence of antithyroidal antibodies. Thyrotoxicosis with destructive thyroiditis was diagnosed within three months of therapy, and ultrasonography of these patients revealed thyroid shrinkage and discordant change in the vascular patterns. DISCUSSION: Decreases in the total T3 and total T4 levels may be related to improvements in the hepatocellular lesions or inflammatory changes similar to those associated with nonthyroidal illnesses. The immune mechanisms and direct effects of interferon-alpha can be associated with thyroiditis. CONCLUSION: Interferon-alpha and ribavirin induce autoimmune and non-autoimmune thyroiditis and hormonal changes (such as decreased total T3 and total T4 levels, which occur despite stable free T4 and TSH levels.

    Full Text Available The aim of this study was to describe a young man with probably the largest pheochromocytoma associated with MEN 2A, described till date. The patient, a non-vegetarian, fifth of eight siblings, married, having five children, presented with episodes of difficult-to-control hypertension requiring over five antihypertensives. He was referred to us with an abdominal CT scan that revealed a 16 cm left-sided adrenal mass. Biochemical testing confirmed a catecholamine secreting pathology. Histopathology confirmed the mass as a pheochromocytoma weighing 1.8 kg. Further evaluation suggested a parathormone-dependent hypercalcemia and a left-sided thyroid mass. Histopathology confirmed parathyroid hyperplasia and medullary carcinoma of the thyroid mixed with papillary carcinoma of thyroid. Putting all the findings together showed that the patient was suffering from multiple endocrine neoplasia 2. Multiple endocrine neoplasia 2A is a rare syndrome. The case is unique in the way it presented, with all the three tumors at the same time. The management was bold and addressed all the three lesions in the same hospital admission. We are also reporting the largest described case of pheochromocytoma from India.

    The aim of this study was to describe a young man with probably the largest pheochromocytoma associated with MEN 2A, described till date. The patient, a non-vegetarian, fifth of eight siblings, married, having five children, presented with episodes of difficult-to-control hypertension requiring over five antihypertensives. He was referred to us with an abdominal CT scan that revealed a 16 cm left-sided adrenal mass. Biochemical testing confirmed a catecholamine secreting pathology. Histopathology confirmed the mass as a pheochromocytoma weighing 1.8 kg. Further evaluation suggested a parathormone-dependent hypercalcemia and a left-sided thyroid mass. Histopathology confirmed parathyroid hyperplasia and medullary carcinoma of the thyroid mixed with papillary carcinoma of thyroid. Putting all the findings together showed that the patient was suffering from multiple endocrine neoplasia 2. Multiple endocrine neoplasia 2A is a rare syndrome. The case is unique in the way it presented, with all the three tumors at the same time. The management was bold and addressed all the three lesions in the same hospital admission. We are also reporting the largest described case of pheochromocytoma from India. PMID:23961501

    Full Text Available Aim. To investigate obstetric features of pregnant women with thyroid disorders and thyroid function tests of their newborn infants. Methods. Women with hypothyroidism and having anti-thyroglobulin (ATG and anti-thyroid peroxidase (anti-TPO antibodies were assigned as group I, women with hypothyroidism who did not have autoantibodies were assigned as group II, and women without thyroid problems were assigned as group III. Results. Pregnant women with autoimmune hypothyroidism (group I had more preterm delivery and their babies needed more frequent neonatal intensive care unit (NICU admission. In group I, one infant was diagnosed with compensated hypothyroidism and one infant had transient hyperthyrotropinemia. Five infants (23.8% in group II had thyroid-stimulating hormone (TSH levels >20 mIU/mL. Only two of them had TSH level >7 mIU/L at the 3rd postnatal week, and all had normal free T4 (FT4. Median maternal TSH level of these five infants with TSH >20 mIU/mL was 6.6 mIU/mL. In group III, six infants (6.5% had TSH levels above >20 mIU/mL at the 1st postnatal week. Conclusion. Infants of mothers with thyroid problems are more likely to have elevated TSH and higher recall rate on neonatal thyroid screening. Women with thyroid disorders and their newborn infants should be followed closely for both obstetrical problems and for thyroid dysfunction.

    Full Text Available Kearns-Sayre syndrome is characterized by onset before 20 years, chronic progressive external opthalmoplegia, pigmentary retinal degeneration, and ataxia (and/or hearth block, and/or high protein content in the cerebrospinal fluid in the presence of mtDNA rearrangements. Multiple endocrine dysfunction associated with this syndrome was rarely reported. In this paper, the Authors report on a female patient with Kearns-Sayre syndrome with large heteroplasmic mtDNA deletion, absence of cytochrome c oxidase in many muscle fibers, partial GH deficiency, hypothyroidism and subsequently insulin dependent diabetes mellitus (IDDM. Anti-thyroid peroxidase and antithyreoglobulin antibodies were present in high titer in serum while anti-islet cell antibodies were absent. The patient developed thyroiditis with Hashimoto encephalopathy. The presence of GH deficiency, autoimmune thyroiditis with hypothyroidism and IDDM distinguishes this case from others and confirms the association of Kearns-Sayre syndrome with multiple endocrine dysfunction. Hashimoto encephalopathy and anti-thyroideal antibodies suggest that in this patient, predisposed by a genetic factor (a mitochondrial deletion anti-thyroideal antibodies may have contributed to the hypothyroidism and, by interfering with cerebral mitochondrial function, may have caused the encephalopathy. GH deficiency and IDDM can be attributed to oxidative phosphorylation deficiency but the autoimmunity may also have played a role in the production of glandular insufficiencies. It seems important to search for endocrine autoimmunity in every case of KSS.

    Objective: To investigate the possible relationship between serum thyroglobulin antibody, thyroid peroxidase antibody levels and the development of AITD. Methods: Thyroid peroxidase antibody (TPO-Ab) level was determined with electrochemilu-minescence assay, the thyroglobulin antibody (TGA) was detected by radiolmmunoassay and peripheral T-cells subsets were examined with monoclonal antibody technic in 87 patients with hyperthyroidism, 83 patients with hypothyroidism and 80 controls. Results: The thyroid peroxidase antibody and thyroglobulin antibody levels in AITD patients (including both hyper and hypothyroid patients) were significantly higher than those in the controls (P<0.01). Conclusion: It is proposed that increase of TPO-Ab and TGA is the cause of the development of AITD. (authors)

    2011-01-01

    Full Text Available Resistance to thyroid hormone (RTH is a rare disorder characterized by variable tissue hyporesponsiveness to thyroid hormone, usually caused by mutations in the thyroid hormone receptor beta (TRβ. It has been reported that the serum of patients with RTH is free of auto-antibodies against thyroglobulin (Tg and thyroid peroxidase (TPO, except in rare cases where coincidental autoimmune thyroiditis is also present. We describe a 13-year-old girl with chronic thyroiditis and RTH. This patient had increased plasma free T3, free T4 at the upper limits with unsuppressed TSH. She had peripheral manifestations of thyroid hormone excess, hypertension and growth acceleration. Anti-TPO antibodies were positive. Sequence analysis of the TRβ gene was performed and revealed a novel mutation I54V in exon 4. The same mutation was also found in the mother and two asymptomatic sisters. The clinical presentation of our patient is not habitual in RTH because growth retardation is frequently reported in this syndrome. The association between RTH and thyroiditis complicate the management of the hypothyroidism.

    Full Text Available Introduction. Autoimmune polyglandular syndrome type 2 is defined as adrenal insufficiency associated with autoimmune primary hypothyroidism and/or with autoimmune type 1 diabetes mellitus, but very rare with myasthenia gravis. Case report. We presented a case of an autoimmune polyglandular syndrome, type 2 associated with myasthenia gravis. A 49-year-old female with symptoms of muscle weakness and low serum levels of cortisol and aldosterone was already diagnosed with primary adrenal insufficiency. Primary hypothyroidism was identified with low values of free thyroxine 4 (FT4 and raised values of thyroidstumulating hormone (TSH. The immune system as a cause of hypothyroidism was confirmed by the presence of thyroid antibodies to peroxidase and TSH receptors. Myasthenia gravis was diagnosed on the basis of a typical clinical feature, positive diagnostic tests and an increased titre of antibodies against the acetylcholine receptors. It was not possible to confirm the immune nature of adrenal insufficiency by the presence of antibodies to 21- hydroxylase. The normal morphological finding of the adrenal glands was an indirect confirmation of the condition as well as the absence of other diseases that might have led to adrenal insufficiency and low levels of both serum cortisol and aldosterone. Hormone replacement therapy, anticholinergic therapy and corticosteroid therapy for myasthenia gravis improved the patient’s general state of health and muscle weakness. Conclusion. This case report indicates a need to examine each patient with an autoimmune disease carefully as this condition may be associated with another autoimmune diseases.

  13. The etiology of thyroid tumours

    International Nuclear Information System (INIS)

    The etiology of thyroid tumors is a complex subject, complicated by the fact that these tumors are not one entity, but separate neoplasms with different histology, evolution and prognosis. The recognized etiological factors of thyroid cancer include the iodine content of the diet, the inheritance, racial predispositions, the presence of an autoimmune thyroiditis and mostly, the exposure of the thyroid gland to external radiation following radiotherapy. The role played by these factors varies from one type of tumor to another. Thyroid radiation probably represents the most important factor in the development of a papillary carcinoma, with other factors (iodine-rich diet, inheritance, racial predispositions) having a minor role. The follicular carcinoma is more common in regions with low-iodine diet, therefore suggesting that TSH stimulation could be an etiological factor of these tumors. Thyroid radiation may also be carcinogenic for follicular carcinoma although less than for papillary carcinoma. Anaplastic carcinoma appears to originate from a papillary carcinoma already in the thyroid gland. In medullary carcinoma, inheritance plays a major role (autosomal dominant) and lymphomas occur in thyroids already affected by autoimmune thyroiditis. Recent experimental studies have suggested other possible cellular factors as responsible for the development of thyroid tumors. They include an alteration of the responsivity of TSH cellular receptors and the monoclonal mutation of C-cells. These new factors could provide a new insight on the etiology of thyroid tumors

    A 61-year-old woman with a history of pernicious anemia presented with progressive muscle weakness and dysarthria. Hypokalemic paralysis (serum potassium, 1.4 mEq/L) due to distal renal tubular acidosis (dRTA) was diagnosed. After excluding several possible causes, dRTA was considered autoimmune. However, the patient did not meet criteria for any of the autoimmune disorders classically associated with dRTA. She had very high antibody titers against parietal cells, intrinsic factor, and thyroid peroxidase (despite normal thyroid function). The patient consented to a kidney biopsy, and acid-base transporters, anion exchanger type 1 (AE1), and pendrin were undetectable by immunofluorescence. Indirect immunofluorescence detected diminished abundance of AE1- and pendrin-expressing intercalated cells in the kidney, as well as staining by the patient's serum of normal human intercalated cells and parietal cells expressing the adenosine triphosphatase hydrogen/potassium pump (H(+)/K(+)-ATPase) in normal human gastric mucosa. The dRTA likely is caused by circulating autoantibodies against intercalated cells, with possible cross-reactivity against structures containing gastric H(+)/K(+)-ATPase. This case demonstrates that in patients with dRTA without a classic autoimmune disorder, autoimmunity may still be the underlying cause. The mechanisms involved in autoantibody development and how dRTA can be caused by highly specific autoantibodies against intercalated cells have yet to be determined. PMID:25533600

  18. Recurrent pregnancy loss in patients with thyroid dysfunction

    Directory of Open Access Journals (Sweden)

    Debanjali Sarkar

    2012-01-01

    Full Text Available Purpose of the Review: Thyroid disturbances are common in women during their reproductive years. Thyroid dysfunction interferes with human reproductive physiology, reduces the likelihood of pregnancy and adversely affects pregnancy outcome, thus becoming relevant in the algorithm of reproductive dysfunction. This review highlights the "gap" in knowledge regarding the contribution of thyroid dysfunction in reproduction. Literature Reviewed: Following implantation, the maintenance of the pregnancy is dependent on a multitude of endocrinological events that will eventually aid in the successful growth and development of the fetus. It is estimated that approximately 8-12% of all pregnancy losses are the result of endocrine factors. Autoimmune thyroid disease is present in around 4% of young females and up to 15% are at risk because they are thyroid antibody-positive. There is a strong relationship between thyroid immunity on one hand and infertility, miscarriage, and thyroid disturbances in pregnancy and postpartum, on the other hand. Even minimal hypothyroidism can increase rates of miscarriage and fetal death and may also have adverse effects on later cognitive development of the offspring. Hyperthyroidism during pregnancy may also have adverse consequences. Summary: Pregnant women with subclinical hypothyroidism or thyroid antibodies have an increased risk of complications, especially pre-eclampsia, perinatal mortality, and miscarriage. Universal screening for thyroid hormone abnormalities is not routinely recommended at present, but thyroid function must be examined in female with fetal loss or menstrual disturbances. Practitioners providing health care for women should be alert to thyroid disorders as an underlying etiology for recurrent pregnancy loss.

    Aim: Conventional radioreceptor-antibody-assays (RAAs) fail in the detection of TSH-receptor antibodies (TRAKs) in 10-30% of patients with Graves' disease (GD). The aim of this study was the evaluation of the diagnostic and clinical impact of a new RRA (DYNOtest {sup trademark} TRAKhuman) which uses the human recombinant TSH-Receptor in the diagnosis of autoimmune thyroid disease. Methods: Sera from 142 consecutive patients (GD: n=50, autoimmune thyroiditis/AIT: n=92) and from 55 controls (31 patients without any thyroid disease and 14 with euthyroid goiter) were evaluated both with the DYNOtest {sup trademark} TRAKhuman-assay and a conventional RRA (TRAK-Assay {sup trademark}). Thyroid in vitro parameters and thyroid sonography were performed in all patients. Results: The DYNOtest {sup trademark} TRAK-assay was significantly superior to the conventional RRA in the diagnosis of GD (p<0,00012), especially in those who were treated by thionamides (p<0,003) and in the diagnosis of TRAK-positive patients with AIT (p<0,003). The majority of TRAK-positive AIT-patients suffered from hypothyroidism. One false positive result in patients with euthyroid goiter was found in the TRAK-Assay {sup trademark} as well as in the DYNOtest {sup trademark} TRAKhuman-Assay. Therefore the specifity of the DYNOtest {sup trademark} TRAKhuman was not inferior compared with the conventional assay. Conclusion: The DYNOtest {sup trademark} TRAK-assay is superior in the diagnostic work up of Graves' disease compared with a conventional TRAK-assay and offers an equal specifity. (orig.)

    The human body is colonized by a large number of microbes that are collectively referred to as the microbiota. They interact with the hosting organism and some do contribute to the physiological maintenance of the general good health thru regulation of some metabolic processes while some others are essential for the synthesis of vitamins and short-chain fatty acids. The abnormal variation, in the quality and/or quantity of individual bacterial species residing in the gastro-intestinal tract, is called “dysmicrobism”. The immune system of the host will respond to these changes at the intestinal mucosa level which could lead to Inflammatory Bowel Diseases (IBD). This inflammatory immune response could subsequently extend to other organs and systems outside the digestive tract such as the thyroid, culminating in thyroiditis. The goal of the present study is to review and analyze data reported in the literature about thyroiditis associated with inflammatory bowel diseases such as Ulcerative Colitis (UC) and Crohn’s Disease (CD). It was reported that similarities of some molecular bacterial components with molecular components of the host are considered among the factors causing IBD through an autoimmune reaction which could involve other non-immune cell types. The axis dysmicrobism-IBD-autoimmune reaction will be investigated as a possible etiopathogenic mechanism to Autoimmune Thyroiditis. If such is the case, then the employment of specific probiotic strains may represent a useful approach to moderate the immune system. PMID:26122213

    Cells have been previously used in experimental models for tolerance induction in organ transplantation and autoimmune diseases. One problem with the therapeutic use of cells is standardization of their preparation. We discuss an immunosuppressive strategy relying on cells irreversibly transformed by a chemotherapeutic drug. Dendritic cells (DCs) of transplant donors pretreated with mitomycin C (MMC) strongly prolonged rat heart allograft survival when injected into recipients before transplantation. Likewise, MMC-DCs loaded with myelin basic protein suppressed autoreactive T cells of MS patients in vitro and prevented experimental autoimmune encephalitis in mice. Comprehensive gene microarray analysis identified genes that possibly make up the suppressive phenotype, comprising glucocorticoid leucine zipper, immunoglobulin-like transcript 3, CD80, CD83, CD86, and apoptotic genes. Based on these findings, a hypothetical model of tolerance induction by MMC-treated DCs is delineated. Finally, we describe the first clinical application of MMC-treated monocyte-enriched donor cells in an attempt to control the rejection of a haploidentical stem cell transplant in a sensitized recipient and discuss the pros and cons of using MMC-treated antigen-presenting cells for tolerance induction. Although many questions remain, MMC-treated cells are a promising clinical tool for controlling allograft rejection and deleterious immune responses in autoimmune diseases. PMID:19393276

    Autoimmune hemolytic anemia is a rare condition in children which differs from the adult form. It is defined by immune-mediated destruction of red blood cells caused by autoantibodies. Characteristics of the autoantibodies are responsible for the various clinical entities. Classifications of autoimmune hemolytic anemia include warm autoimmune hemolytic anemia, cold autoimmune hemolytic anemia, and paroxysmal cold hemoglobinuria. For each classification, this review discusses the epidemiology, etiology, clinical presentation, laboratory evaluation, and treatment options. PMID:26575109

    Both Graves' disease and chronic thyroiditis (Hashimoto's thyroiditis) are autoimmune diseases of thyroid gland. Graves' disease is caused by stimulation of TSH receptor located on the thyroid gland by an antibody, which is known as TSH receptor antibody (TRAb). Furthermore, this may lead to hyperplasia and hyperfunction of the thyroid gland. On the contrary, the cause of Hashimoto's thyroiditis is thought due to a TSH stimulation-blocking antibody (TSBAb) which blocks the action of TSH hormone and subsequently brings damage and atrophy to thyroid gland. Approximately 15-20% of patients with Graves' disease had been reported to have spontaneous hypothyroidism resulting from the chronic thyroiditis (Hashimoto's disease). Pathogenesis for chronic thyroiditis following anti-thyroid drug treatment in patients with Graves' disease remains unclear. It has been estimated that chronic thyroiditis or Hashimoto's disease, which occurs following the Graves' disease episode is due to extended immune response in Graves' disease. It includes the immune response to endogenous thyroid antigens, i.e. thyroid peroxidase and thyroglobulin, which may enhance lymphocyte infiltration and finally causes Hashimoto's thyroiditis. We report four cases of chronic thyroiditis (Hashimoto's disease) in patients who have been previously diagnosed with Graves' hyperthyroidism. In three cases, Hashimoto's thyroiditis occurs in 7 to 25 years after the treatment of Grave's disease; while the other case has it only after few months of Grave's disease treatment. The diagnosis of Hashimoto's disease (chronic thyroiditis) was based on clinical manifestation, high TSHs level, positive thyroid peroxidase antibody and thyroglobulin antibody, and supported by positive results of fine needle aspiration biopsy. Moreover, the result of histopathological test has also confirmed the diagnosis in two cases. All cases have been successfully treated by levothyroxine treatment. PMID:20305330

    The high percentage of disease-discordant pairs of monozygotic twins demonstrates the central role of environmental factors in the etiology of autoimmune diseases. Efforts were first focussed on the search for triggering factors. The study of animal models has clearly shown that infections may trigger autoimmune diseases, as in the case of Coxsackie B4 virus in type I diabetes and the encephalomyocarditis virus in autoimmune myositis, two models in which viruses are thought to act by increasing immunogenicity of autoantigens secondary to local inflammation. The induction of a Guillain-Barré syndrome in rabbits after immunization with a peptide derived from Campylobacter jejuni is explained by mimicry between C. jejuni antigens and peripheral nerve axonal antigens. Other models involve chemical modification of autoantigens, as in the case of iodine-induced autoimmune thyroiditis. These mechanisms have so far only limited clinical counterparts (rheumatic fever, Guillain-Barré syndrome and drug-induced lupus or myasthenia gravis) but one may assume that unknown viruses may be at the origin of a number of chronic autoimmune diseases, such as type I diabetes and multiple sclerosis) as illustrated by the convergent data incriminating IFN-alpha in the pathophysiology of type I diabetes and systemic lupus erythematosus. Perhaps the difficulties met in identifying the etiologic viruses are due to the long lag time between the initial causal infection and onset of clinical disease. More surprisingly, infections may also protect from autoimmune diseases. Western countries are being confronted with a disturbing increase in the incidence of most immune disorders, including autoimmune and allergic diseases, inflammatory bowel diseases, and some lymphocyte malignancies. Converging epidemiological evidence indicates that this increase is linked to improvement of the socio-economic level of these countries, posing the question of the causal relationship and more precisely the

    Full Text Available Autoimmune endocrinopathies and, less commonly, thyroid autoimmune disease have been reported in patients with sarcoidosis. Similarities exist in the pathogenesis of these two conditions. Concomitant sarcoidosis in the thyroid gland in patients with Graves′ disease may contribute to the resistance to antithyroid drugs and radioiodine therapy. We present the clinical, laboratory, imaging, and pathologic findings of a patient with Graves′ disease who was unresponsive to medical management. This 37-year-old man presented with thyrotoxicosis. Thyroid hormone assays and 99m Technitium findings were consistent with Graves′ disease. He was also found to have hilar lymphadenopathy. Patient failed to achieve remission with high doses of antithyroid drugs and 2 sessions of radioiodine ablative therapy.Histopathology of lymph nodesdisclosed noncaseating granulomas, consistent with sarcoidosis. Patient′s thyrotoxicosis subsided only following steroid administration. The histopathology of the thyroid gland on aspiration and the subsidence of symptoms with steroids reiterate the possibility of thyroid sarcoidosis. This diagnosis needs biopsy for confirmation, which our patient didn′t consent for.

    Turner Syndrome (TS) is a common genetic disorder, affecting female individuals, resulting from the partial or complete absence of one sex chromosome, and occurring in approximately 50 per 100,000 liveborn girls. TS is associated with reduced adult height and with gonadal dysgenesis, leading to insufficient circulating levels of female sex steroids and to infertility. Morbidity and mortality are increased in TS but average intellectual performance is within the normal range. TS is closely associated to the presence of autoantibodies and autoimmune diseases (AID), especially autoimmune thyroiditis and inflammatory bowel disease. Despite the fact that the strong association between TS and AID is well known and has been widely studied, the underlying immunopathogenic mechanism remains partially unexplained. Recent studies have displayed how TS patients do not show an excess of immunogenic risk markers. This is evocative for a higher responsibility of X-chromosome abnormalities in the development of AID, and particularly of X-genes involved in immune response. For instance, the long arm of the X chromosome hosts a MHC-locus, so the loss of that region may lead to a deficiency in immune regulation. Currently no firm guidelines for diagnosis exist. In conclusion, TS is a condition associated with a number of autoimmune manifestations. Individuals with TS need life-long medical attention. As a consequence of these findings, early diagnosis and regular screening for potential associated autoimmune conditions are essential in the medical follow-up of TS patients. PMID:22154619

    Thyroid disease does occur in the pediatric patient, and imaging plays an important role in its evaluation. A review is presented of normal development of the thyroid gland, the technique and indications for thyroid sonography, and key imaging features of congenital thyroid disorders (ectopic or absent thyroid, infantile goiter, thyroglossal duct remnants), benign thyroid masses (follicular adenoma, degenerative nodules, colloid and thyroid cysts), malignant masses (follicular, papillary and medullary carcinoma) and diffuse thyroid disease (acute bacterial thyroiditis, Hashimoto's thyroiditis, Grave's disease).

    2014-01-01

    Full Text Available Background. A recent study has reported that high circulating 25-hydroxyvitamin D [25(OHD] is associated with low circulating thyroid-stimulating hormone (TSH levels, but only in younger individuals. The goal of the present study was to explore the relationship between vitamin D status and circulating TSH levels with thyroid autoimmunity and thyroid hormone levels taken into consideration in a population-based health survey of middle-aged and elderly individuals. Methods. A total of 1,424 Chinese adults, aged 41–78 years, were enrolled in this cross-sectional study. Serum levels of 25(OHD, TSH, thyroid hormones, and thyroid autoantibodies were measured. Results. The prevalence of vitamin D insufficiency was 94.29% in males and 97.22% in females, and the prevalence of vitamin D deficiency was 55.61% in males and 69.64% in females. Vitamin D status was not associated with positive thyroid autoantibodies after controlling for age, gender, body mass index, and smoking status. Higher 25(OHD levels were associated with lower TSH levels after controlling for age, FT4 and FT3 levels, thyroid volume, the presence of thyroid nodule(s, and smoking status in males. Conclusion. High vitamin D status in middle-aged and elderly males was associated with low circulating TSH levels independent of thyroid hormone levels.

  13. Anti-thyroid peroxidase antibodies: Its effect on thyroid gland and breast tissue

    Full Text Available Thyroid peroxidase (TPO is a key enzyme in the synthesis of thyroid hormone. TPO is involved in thyroid hormone synthesis (organification and coupling reactions. TPO is a major antigen corresponding to thyroid-microsomal autoantibodies. Anti-TPO auto antibodies are very important to diagnose autoimmune thyroid diseases and also in estimating its clinical course. Autoimmune thyroid disease is detected mostly by measuring circulating antibodies to thyroglobulin which is uncommon measurement of antibodies to TPO that gives reliable information about autoimmune thyroid disease. Eighty percent of Grave′s disease patients have high levels of antiTPO antibodies. About 4% of subclinical hypothyroid patients with positive TPO antibodies develop clinical hypothyroidism. There is always a controversy on the relationship between breast cancer and thyroid disorders. As these tissues, i.e., breast and thyroid, originate embryologically from the same type of cells, hypothyroid/hyperthyroid females are more prone to develop benign or malignant breast tumors. The studies on breast cancer patients indicate increased thyroid disorders in breast cancer patients, most commonly Hashimoto′s thyroiditis accounts to increased thyroid disorders in these patients. This is independent of hormonal receptor status of the patient. These findings suggest the usefulness of screening for thyroid disease in any patient with breast cancer.

  17. Thyroid cancer

    International Nuclear Information System (INIS)

    Special place in oncology belongs to thyroid cancer as it is a cancer originating from hormonally active tissue. 90 % of endocrine neoplasia are represented by thyroid cancer. It is a relatively rare cancer and due to its heterogeneity it encompasses spectrum of therapeutic approaches with interdisciplinary management which includes various implications for prognosis and lethality. Generally, the prognosis for patients with differentiated thyroid cancer is good, a 10 years survival rate is at 85 %. Standard treatment includes surgical therapy, TSH suppressive therapy and ablation of the thyroid remnant with radioactive iodine. Patients with recurrent disease, disseminated disease present at the time of diagnosis, patients unsuitable for surgical treatment or for treatment with radioiodine still remain a therapeutic challenge. As there is no effective systematic treatment there is a hope for new therapy with multiple kinase inhibitors such as vandetanib, sorafenib, cabozantinib a lenvatinib which is based on promising results of several studies.

    Full Text Available About 8% of the general population suffers from autoimmune diseases, from which 78% are women. One of the most important causes of thyroid diseases is autoimmunity in origin, and it seems that people with thyroid diseases present more signs of asthma. This study was therefore designed to investigate the frequency of autoimmune thyroid diseases in women suffering from bronchial asthma.In a cross-sectional study, 100 women with asthma and 100 women as control group were tested for thyroid function and anti-thyroid peroxidase antibody (anti-TPO Ab measurements.  The  asthmatic  patients  were  selected  based  on  having  chronic  cough, dyspnea, wheezing and clinical examination of the chest. The diagnosis was confirmed by pulmonary function tests. Blood tests were done by electrochemiluminescence immunoassay method.No hyperthyroid patient was found in either group. Serum TSH and Total T4 levels were not statistically different between the two groups, but serum anti-TPO Ab levels in women with asthma (74±13.6  IU/ml  was significantly higher than  control  group  (45.24±10.56 IU/ml. After adjusting the effect of age and BMI, the relationship between asthma and anti- TPO Ab (>50 IU/ml was statistically significant (OR=3.3, P<0.01.Positive anti-TPO Ab in asthmatic patients may show presence of a hidden autoimmune thyroiditis in these patients. We suggested checking asthmatic patients for thyroid diseases.

    Full Text Available Although the role of interleukin-2 (IL-2 and interferon gamma (gIFN is still poorly understood in hyperthyroid diseases, it is reasonable to assume that these cytokines may be present at higher levels in Graves' disease (GD than in other primarily non-autoimmune thyroid diseases. In order to look for an easy method to distinguish GD from primarily non-autoimmune causes of hyperthyroidism, we compared 13 healthy individuals with 21 treated and untreated hyperthyroid GD patients and with 19 patients with hyperthyroidism due to other etiologies: 7 cases of multinodular goiter, 5 cases of excessive hormone replacement and 7 cases of amiodarone-associated hyperthyroidism. All patients presented low TSH levels and a dubious clinical thyroid state. We found a good correlation between TSH and serum IL-2 levels (r = 0.56; PgIFN (P<0.01 levels were lower in the hyperthyroid group of patients than in control subjects, suggesting a depressed TH1 pattern in the T-cell subset of hyperthyroid patients. GD had normal IL-2 levels, while patients with other forms of thyrotoxicosis presented decreased IL-2 levels (P<0.05. There was no difference between treated and untreated GD patients. We suggest that the direct measurement of serum IL-2 level may help to confirm hyperthyroidism caused by GD.

    Hashimoto thyroiditis (HT) is an autoimmune disease, known to be the most common cause of hypothyroidism in nonendemic goitrous areas. It is usually characterized by symmetric, painless, and diffused but sometimes localized swelling of the thyroid gland with features of hypothyroidism. Papillary thyroid carcinoma (PTC), on the other hand, is the most common yet less aggressive form of thyroid cancer, especially in iodine-deficient areas. The coexistence of the two diseases is possible but not...

    Full Text Available Abstract Introduction Autoimmune polyendocrine syndrome type 2 is a rare disorder. Its prevalence in western populations has been reported as 1.5 to 4.5/100,000. On the other hand, its prevalence in Egypt is unknown. It is characterized by the association of autoimmune Addison’s disease with thyroid autoimmune diseases and/or type I diabetes mellitus. Hepatitis C virus infection is an important public health issue worldwide. Egypt has the highest prevalence of hepatitis C virus infection of any country in the world. It is estimated to be 8% in urban and 25% in rural areas. We present the case of an Egyptian child with autoimmune polyendocrine syndrome type 2 associated with chronic hepatitis C infection. Case presentation A 14-year-old Egyptian boy with type 1 diabetes mellitus was referred to our institution for an evaluation of recurrent attacks of hypoglycemia of two months duration. The initial clinical examination revealed hypotension as well as vitiligo of the skin. He had high potassium, low sodium, low cortisol, high adrenocorticotropic hormone, slightly high thyroid stimulating levels with strong positivity of anti-thyroglobulin and anti-thyroid peroxidase antibodies. The hepatitis C antibody and hepatitis C virus–polymerase chain reaction were positive. Based on these findings, a diagnosis of autoimmune polyendocrine syndrome type 2 with chronic hepatitis C was made. He was started on hydrocortisone (10mg twice daily, fludrocortisone (0.1mg twice daily and multiple daily doses of insulin. He showed great improvement of his symptoms on the prescribed treatment. Conclusions The importance of the early diagnosis of autoimmune polyendocrine syndrome type 2 and the possibility of its association with chronic hepatitis C infection should be considered in order to implement the proper management of such cases.

    The aim of our study is to establish the reference intervals (RIs) of thyroid hormones in a previously iodine-deficient area but presently more than iodine-adequate area of Western China, and also to investigate the factors which affect thyroid function. The cross-sectional study conducted in Xi'an, was based on 2007-2008 China National Diabetes and Metabolic Disorders Survey. Among 1286 participating adults, 717 were finally included as reference population. Thyrotropin (TSH), total triiodothyronine (T3), free triiodothyronine (FT3), total thyroxine (T4), free thyroxine (FT4), thyroperoxidase antibody (TPO-Ab) and thyroglobulin antibody (Tg-Ab) were measured. Thyroid ultrasound examination was also performed. The present study established the new RIs of serum TSH (0.43-5.51 mIU/L), FT4 (11.0-20.4 pmol/L), FT3 (3.63-5.73 pmol/L), T4 (67.8-157 mmol/L) and T3 (1.08-2.20 mmol/L), which were different from the data provided by the manufacturers. Significant differences among all the age groups were observed in FT3, but neither in TSH nor in FT4. The TSH levels in adults with pathologic ultrasonography results or positive thyroid autoantibody were significantly higher than those in reference adults. Our present results provide valuable references for the diagnosis of thyroid diseases in population of Western China. Considering that most inland areas of China have faced the challenge of the transition from iodine deficiency to adequacy or more than adequacy, we recommend physicians utilize our RIs to determine thyroid diseases in the similar areas with Xi'an in China.

    The effect of treatment on thyroid antibody production and T cell reactivity to thyroid antigens was studied in 15 patients with Graves` disease (GD) before and after thyroidectomy, 19 patients with GD before and after radioactive iodine (RAI) therapy, and 9 patients maintained euthyroid on antithyroid drugs (ATD). In GD patients, the responses of peripheral blood mononuclear cells (PBMC) and TSH receptor (TSHR)-specific T cell lines to recombinant human TSHR extracellular domain, thyroglobulin, and TSHR peptides were examined on the day of surgery or RAI therapy (day 0) and also 6-8 weeks and 3-6 months thereafter. Reactivity to TSHR peptides before surgery was heterogeneous and spanned the entire extracellular domain. Six to 8 weeks after subtotal thyroidectomy, the number of patients` PBMC responding to any peptide and the average number of recognized peptides decreased. A further decrease in the T cell reactivity to TSHR peptides was observed 3-6 months after surgery. The responses of PBMC from Graves` patients before RAI therapy were less than those in the presurgical group. Six to 8 weeks after RAI therapy, the number of patients responding to any peptide and the average number of recognized peptides increased. Three to 6 months after RAI, T cell responses to TSHR peptides were less than those 6-8 weeks after RAI therapy, but still higher than the values on day 0. Responses of PBMC from patients with GD, maintained euthyroid on ATD, were lower than those before surgery or RAI therapy. The reactivity of T cell lines in different groups reflected a pattern similar to PBMC after treatment. TSHR antibody and microsomal antibody levels decreased after surgery, but increased after RAI therapy. The difference in the number of recognized peptides by patients` PBMC before RAI and surgery may reflect the effect of long term therapy with ATD in the patients before RAI vs. the shorter period in patients before surgery. 38 refs., 2 figs., 5 tabs.

    Antibodies against the Na/I symporter (anti-NIS ab) have been found in adult patients with autoimmune thyroid diseases. As easily available for the immune system, NIS can play a role in the initial stage of autoimmune thyroid diseases. Children with Turner's syndrome (TS) being at high risk of autoimmune thyroid disease development seem a valuable group for the investigation of the early autoimmune process. The aim of the study was to investigate the presence of anti-NIS ab and its potential clinical significance in TS children. Fifty four girls with TS were examined (age 11.9 ± 2.46 years), and 23 healthy girls with normal thyroid function, free of autoimmune diseases. Anti-NIS antibodies were measured by the in-house ELISA method and the Western blotting. Sera considered positive for anti-NIS ab were used for the iodide uptake bioassay using COS7 cells stably transfected with hNIS. In all patients the thyroid function, antithyroid antibodies presence and thyroid ultrasonography were evaluated. In 20% of the patients a subclinical hypothyroidism was diagnosed and 70.4% had antithyroid antibodies (anti-TPO - 64.8% and Anti-Tg - 24%). Anti-NISab were present in 14.8% girls with TS and in none of the control group. Their presence was unrelated to other antithyroid antibodies titre or patients' age. A positive correlation between the anti-NIS ab presence and the hypothyroidism was found (p < 0.04). Anti-NIS ab-positive sera did not suppress iodine uptake. In conclusion, anti-NIS antibodies were present in 14.8% of children with TS and they were related to the presence of hypothyroidism. PMID:22836628

    Dual ectopic thyroid is a rare presentation of thyroid ectopia. Only a few cases have been reported in the world literature. Dual ectopic thyroid in the presence of a normally located thyroid is even rarer. We report a case of dual ectopic thyroid in the lingual and submandibular areas in a seventeen-year-old female with hypoplastic thyroid gland in its normal location. The patient presented with a midline swelling at the base of tongue with dysphagia. Thyroid function test revealed primary h...

    Autoimmunity against pancreatic islet beta cells is strongly associated with proinsulin, insulin, or both. The insulin autoreactivity is particularly pronounced in children with young age at onset of type 1 diabetes. Possible mechanisms for (pro)insulin autoimmunity may involve beta-cell destruction resulting in proinsulin peptide presentation on HLA-DR-DQ Class II molecules in pancreatic draining lymphnodes. Recent data on proinsulin peptide binding to type 1 diabetes-associated HLA-DQ2 and ...

    Full Text Available Hashimoto thyroiditis (HT is an autoimmune disease, known to be the most common cause of hypothyroidism in nonendemic goitrous areas. It is usually characterized by symmetric, painless, and diffused but sometimes localized swelling of the thyroid gland with features of hypothyroidism. Papillary thyroid carcinoma (PTC, on the other hand, is the most common yet less aggressive form of thyroid cancer, especially in iodine-deficient areas. The coexistence of the two diseases is possible but not common. This case study reports a 50-year-old female with a 10-year history of a huge goiter, which was essentially symptom-free until about 3 months prior to presentation when the patient started complaining of neck pain, dysphagia, productive cough, and cold intolerance. Physical examination revealed focal cystic and tender area in the multinodular swelling and associated cervical lymphadenopathy on the left side of the neck. The serum thyroid stimulating hormone was high, sub-normal T3, and the T4 was low. The fine needle aspiration cytology yielded 10 ml of aspirate of pus admixed with altered blood which on microscopy showed a few suspicious follicular epithelial cells with open nuclei admixed with mainly neutrophil polymorphs, siderophages, and foam cells in a hemorrhagic background. The patient had an incision biopsy that showed areas displaying PTC and HT.

    Full Text Available BACKGROUND Thyroid diseases and diabetes mellitus are the most common endocrine diseases during pregnancy. Internal Medicine doctors could be involved in the management of pregnant women affected by thyroid diseases, in particular if an Endocrine Unit lacks in the hospital; it is mandatory that they have the skills to cope with these diseases. METHODS In this work authors describe the most common thyroid abnormalities that can occur during pregnancy: hypothyroidism (clinical and subclinical, hyperthyroidism (clinical and sub-clinical, autoimmune thyroiditis (in particular the so called post-partum thyroiditis, nodular diseases and cancer. They discuss moreover the peculiar pathophysiologic mechanisms by which these diseases appear, the diagnostic tools and the therapies, according to their own experience and the more recent international guidelines. RESULTS AND CONCLUSIONS It is important to evaluate thyroid function tests before and during pregnancy, at 16th and 28th gestational week; it is mandatory to cure also the “sub-clinical” hypothyroidism during pregnancy, when TSH level are higher than 5 μIU/mL; the optimal dose of levo-thyroxine during pregnancy is, average, 30-50% higher than that used before pregnancy; it is not correct to treat mild or sub-clinical hyperthyroidism; propylthyouracil is the best drug to treat hyperthyroidism during pregnancy; the post-partum thyroiditis is generally transient, so that a careful monitoring of thyroid function is advisable, in particular after 9-12 months of therapy; thyroid cancer, if discovered during pregnancy, generally has no negative effects on the outcome of the pregnancy; it would be better to treat surgically thyroid cancer during the last trimester of the pregnancy.

    The authors consider the issues related to pathogenesis, clinical features, diagnosis and treatment of autoimmune encephalitis. It has been demonstrated that the development of autoimmune encephalitis can be associated with the oncologic process or be of idiopathic character. The pathogenesis of autoimmune encephalitis is caused by the production of antibodies that directly or indirectly (via T-cell mechanism) damage exo-and/or endocellular structures of the nerve cells. The presence of antobodies to endocellular structures of neurons in the cerebrospinal fluid of patients with autoimmune encephalitis in the vast majority of cases (> 95%) indicates the concomitant oncologic process, the presence of antibodies to membranes or neuronal synapses can be not associated with the oncologic process. Along with complex examination, including neuroimaging, EEG, cerebrospinal fluid and antibodies, the diagnostic algorithm in autoimmune encephalitis should include the search for the nidus of cancer. The treatment algorithm in autoimmune encephalitis included the combined immunosupressive therapy, plasmapheresis, immunoglobulines, cytostatics as well as treatment of the oncologic process.

    2016-01-01

    Summary A 71-year-old woman with severe right lower leg pain, edema and erythema was presented to the Emergency Department and was found to have an extensive deep vein thrombosis (DVT) confirmed by ultrasound. She underwent an extensive evaluation due to her prior history of malignancy and new hypercoagulable state, but no evidence of recurrent disease was detected. Further investigation revealed pernicious anemia (PA), confirmed by the presence of a macrocytic anemia (MCV=115.8fL/red cell, Hgb=9.0g/dL), decreased serum B12 levels (56pg/mL), with resultant increased methylmalonic acid (5303nmol/L) and hyperhomocysteinemia (131μmol/L), the presumed etiology of the DVT. The patient also suffered from autoimmune thyroid disease (AITD), and both antithyroglobulin and anti-intrinsic factor antibodies were detected. She responded briskly to anticoagulation with heparin and coumadin and treatment of PA with intramuscular vitamin B12 injections. Our case suggests that a DVT secondary to hyperhomocystenemia may represent the first sign of polyglandular autoimmune syndrome III-B (PAS III-B), defined as the coexistent autoimmune conditions AITD and PA. It is important to recognize this clinical entity, as patients may not only require acute treatment with vitamin B12 supplementation and prolonged anticoagulation, as in this patient, but may also harbor other autoimmune diseases. Learning points A DVT can be the first physical manifestation of a polyglandular autoimmune syndrome. Hyperhomocysteinemia secondary to pernicious anemia should be considered as an etiology of an unprovoked DVT in a euthyroid patient with autoimmune thyroid disease. Patients with DVT secondary to hyperhomocysteinemia should undergo screening for the presence of co-existent autoimmune diseases in addition to treatment with B12 supplementation and anticoagulation to prevent recurrent thromboembolism.

    Full Text Available Graves' disease is a common condition and is known to have a wide range of effects on a variety of organs. Hepatic dysfunction ranging from mild to severe due to direct effect of high circulating thyroid hormones as well as a deleterious effect of antithyroid medications (methimazole and propylthiouracil has been well - documented in literature. However, severe autoimmune hepatitis (AIH associated with Graves' disease is rare and limited to few case reports only. A 38-year-old woman presented with abdominal pain and yellowish discolouration of conjunctivae. On investigation, she was found to have Graves' disease and AIH. The liver histopathology showed typical features of AIH. She responded excellently to glucocorticoid therapy with normalisation of thyroid function and liver histology. The case is discussed with relevant literature review.

    The aetiology of porphyria cutanea tarda (PCT) has not been elucidated, but the possibility of an autoimmune mechanism has been proposed. We report a case of an unknown clinical combination of PCT with autoimmune hypothyroidism, alopecia universalis and vitiligo with thyroid and parietal cell circulating antibodies. This is highly suggestive of underlying autoimmune damage in this patient. PMID:1803247

    Thyroid lymphoepithelial complexes (LECos) are rare, being reported in lymphoma, Graves-Basedow disease, Hashimoto thyroiditis, pericarcinomatous thyroid or in the context of branchial cleft-like cysts. Here we report immunohistochemical expression of cytokeratin 5/6, P63 and TTF1 in 6 cases of thyroid LECos. Two cases had carbimazole treatment for hyperthyroidia and Graves disease. Anti-thyroglobulin, -thyroperoxidase or -TSH antibodies were detected in 4 cases. NSAID or poviodone iodine allergy were present in 2 cases. The treatment consisted in total thyroidectomy or lobectomy. Microscopy showed nodular goiter and focal lymphocytic thyroiditis. Basaloid LECos were seen in all thyroids while squamoid LECos in 2. Associated lesions were papillary thyroid microcarcinoma (2 cases), solid cell nest, thyroglosal duct remnant, lymphoepithelial cyst and thymus-parathyroid unit (one case each). Cytokeratin 5/6 was expressed in both squamoid and basaloid LECos along with P63. TTF1 expression was faint or absent. In conclusion LECos may occur in the context of autoimmune thyroiditis or of a specific immune susceptibility background. The expression of CK5/6 and of P63 suggests a squamous differentiation including in the basaloid LECos. The etiologic relevance of these immunostainings remains limited although rather suggestive of a metaplastic process than of migration-abnormalities. PMID:27130144

  3. The effect of lithium on thyroid function in patients with bipolar disorder

    Directory of Open Access Journals (Sweden)

    Kraszewska, Agnieszka

    2014-06-01

    Full Text Available Since 1963 lithium treatment has been the best proven long-term pharmacotherapy for bipolar disorder (BD, both in the prevention of depressive and manic episodes, along with the reduction of the suicide risk. Thyroid gland and the hypothalamic-pituitary-thyroid (HPT axis play a role in the pathophysiology, clinical course and treatment of BD. The influence of lithium on the thyroid gland is one of the key side effects in the long-term therapy with this drug. Lithium is accumulated in the thyroid gland at 3 to 4-fold higher concentrations as compared to its plasma levels. Its administration results in the reduced production with release inhibition of thyroid hormones, altering the immune processes of this gland. The most common thyroid side effects associated with long-term lithium treatment are goiter and hypothyroidism. Hyperthyroidism is a rare complication of lithium therapy. Lithium may also induce an increase in the thyroid autoimmunity, especially if such change had been present before lithium treatment producing structural changes in this gland. This paper reviews the management of complications described above as well as recommendations for monitoring of thyroid function in patients receiving long-term lithium treatment are discussed.

    Thyroid hemiagenesis is a rare congenital anomaly resulting from failure of one thyroid lobe development. We report a 23-year-old female presented with Hashimoto's thyroiditis in left lobe, associated with hemiagenesis of right lobe and isthmus which was previously diagnosed as Graves' hyperthyroidism, but developed further into Hashimoto's thyroiditis after being treated with antithyroid drugs. The symptoms of hyperthyroidism in the current case led to the diagnostic confirmation by scintiscanning of an absent lobe. The antithyroid pharmacotherapy by thiamazole was used. However, due to symptoms of hypothyroidism, it was discontinued two months later, so thyroid hormone substitution was reintroduced. Antithyroid antibody studies and ultrasonography documented the presence of Hashimoto's thyroiditis. PMID:24198979

    International Nuclear Information System (INIS)

    A short revision of thyroid physiology is done. The radioisotopes of common use in thyroid investigation and the choice of the most appropriated ones are discussed. A table showing radioisotopes frequently used in this study, with their main characteristics is presented. Among several isotopic assays in thyroid propaedeutics, those that refer to the function study, topographic studies and tests 'in vitro' are pointed out. Exploration methods 'in vivo' are treated, such as: thyroid uptake; urinary excretion; thyroid scintigraphy, with scintigraphic imagings; stimulation test by TSH; suppression test; pbi; clearance test with perchlorate; iodine deficiency test and thyroid study with technetium. 'In vitro' proofs like triiodothyronine (T3) and thyroxine (T4) assays, as well as free thyroxine index, are treated. At last, the therapeutics by Iodine 131 is commented and emphasis is given to its application on the treatment of hyperthyroidism and thyroid carcinoma

    Autoantibodies targeting proteins at the neuromuscular junction are known to cause several distinct myasthenic syndromes. Recently, autoantibodies targeting neurotransmitter receptors and associated proteins have also emerged as a cause of severe, but potentially treatable, diseases of the CNS. Here, we review the clinical evidence as well as in vitro and in vivo experimental evidence that autoantibodies account for myasthenic syndromes and autoimmune disorders of the CNS by disrupting the functional or structural integrity of synapses. Studying neurological and psychiatric diseases of autoimmune origin may provide new insights into the cellular and circuit mechanisms underlying a broad range of CNS disorders. PMID:26806629

    Full Text Available Khalid A El Baba1, Sami T Azar21Department of Internal Medicine, Division of Endocrinology, Bahrain Specialist Hospital, Manama, Bahrain; 2Department of Internal Medicine, Division of Endocrinology, American University of Beirut-Medical Center, New York, NY, USAAbstract: Timely treatment of thyroid disease during pregnancy is important in preventing adverse maternal and fetal outcomes. Thyroid abnormalities are very often subclinical in nature and not easily recognized without specific screening programs. Even mild maternal thyroid hormone deficiency may lead to neurodevelopment complications in the fetus. The main diagnostic indicator of thyroid disease is the measurement of serum thyroid-stimulating hormone and free thyroxine levels. Availability of gestation-age-specific thyroid-stimulating hormone thresholds is an important aid in the accurate diagnosis and treatment of thyroid dysfunction. Pregnancy-specific free thyroxine thresholds not presently available are also required. Large-scale intervention trials are urgently needed to assess the efficacy of preconception or early pregnancy screening for thyroid disorders. Accurate interpretation of both antepartum and postpartum levels of thyroid hormones is important in preventing pregnancy-related complication secondary to thyroid dysfunction. This article sheds light on the best ways of management of thyroid dysfunction during pregnancy in order to prevent any possible maternal or fetal complication.Keywords: TSH, HCG, TBG

    Full Text Available Vitiligo is a common skin disorder, and the pathogenesis is unknown. An increased prevalence of autoimmune thyroid diseases has been described in these patients. The aim of this study is to assess the prevalence of thyroid dysfunction and hypoparathyroidism in patients with vitiligo. Materials and Methods: One hundred and nine patients (38 males and 71 females with vitiligo were enrolled. Thyroid physical examination was carried out. Thyroid function tests, thyroid antibodies, calcium and phosphorus were assessed. The collected data were analysed by SPSS version 11. Results: Thyromegaly was found in 30.1% of patients. Hypothyroidism was found in 16 (15.7% out of 109 cases. Two of them had clinical and 14 had subclinical hypothyroidism. One patient had Grave′s disease. Antibody positivity was the most common disorder (anti-TPO and anti-tg were positive in 36.7 and 32.1%, respectively. No patient had hypoparathyroidism. Conclusion: According to our study, thyroid dysfunction, particulary hypothyroidism and thyroid antibodies increase in patients with vitiligo. We recommend thyroid antibodies assessment and thyroid function evaluation in these patients.

    Thyroid function was investigated in 100 manic-depressive patients. Goiter was more common in patients treated with lithium for 1-5 years (44%) or more than 10 years (50%) than in patients who never received lithium (16%). Smoking contributed significantly to thyroid size and goiter. In nonsmoking patients, ultrasonically determined thyroid volume was significantly related to treatment duration. The mechanism behind this increased thyroid volume is unclear, as most patients had normal serum thyrotropin levels and no thyroid autoimmunity. Subclinical or overt hypothyroidism was found in 4% and 21% of patients treated for 1-5 and more than 10 years, respectively. Since few hypothyroid patients had autoimmunity or goiter, lithium may affect the thyroid gland directly. PMID:2221166

    Autoimmune hepatitis is a rare, chronic inflammatory disorder which has been associated with a number of other auto-immune conditions. However, there are no reports in the medical literature of an association with microscopic (lymphocytic) colitis. We report the case of a 53-year-old woman with several autoimmune conditions, including lymphocytic colitis, who presented with an acute hepatitis. On the basis of the clinical features, serology, and histopathology, we diagnosed autoimmune hepatitis. To our knowledge, this is the first report of autoimmune hepatitis in association with lymphocytic colitis, and lends support to the theory of an autoimmune etiology for lymphocytic colitis.

  12. Effect of Associated Autoimmune Diseases on Type 1 Diabetes Mellitus Incidence and Metabolic Control in Children and Adolescents

    Science.gov (United States)

    2016-01-01

    Type 1 diabetes mellitus (T1DM) is one of the most common chronic diseases developing in childhood. The incidence of the disease in children increases for unknown reasons at a rate from 3 to 5% every year worldwide. The background of T1DM is associated with the autoimmune process of pancreatic beta cell destruction, which leads to absolute insulin deficiency and organ damage. Complex interactions between environmental and genetic factors contribute to the development of T1DM in genetically predisposed patients. The T1DM-inducing autoimmune process can also affect other organs, resulting in development of additional autoimmune diseases in the patient, thereby impeding diabetes control. The most common T1DM comorbidities include autoimmune thyroid diseases, celiac disease, and autoimmune gastritis; additionally, diabetes can be a component of PAS (Polyglandular Autoimmune Syndrome). The aim of this review is to assess the prevalence of T1DM-associated autoimmune diseases in children and adolescents and their impact on the course of T1DM. We also present suggestions concerning screening tests. PMID:27525273

    2013-01-01

    Full Text Available Abstract Subclinical hypothyroidism (SH is a condition characterized by a mild persistent thyroid failure. The main cause is represented by autoimmune thyroiditis, but mutations in genes encoding proteins involved in TSH pathway are thought to be responsible for SH, particularly in cases arising in familial settings. Patients with the syndrome of TSH unresponsiveness may have compensated or overt hypothyroidism with a wide spectrum of clinical and morphological alterations depending on the degree of impairment of TSH-receptor (TSH-R function. We describe the case of two brothers with non autoimmune SH carrying the same heterozygous mutation in the extracellular domain of TSH-R and presenting with different clinical, biochemical and morphological features. The first one had only a slight persistent elevation of TSH, a normal thyroid ultrasound and did never require l- thyroxine (L-T4 replacement treatment. The second one had a neonatal persistent moderate TSH levels increase associated with a thyroid gland hypoplasia and was treated with L-T4 since the first months of life. These two cases support the recent association of TSH-R mutations inheritance as an autosomal dominant pattern with variable expressivity and suggest that the decision to start replacement therapy in patients with persistent SH due to TSH resistance should be individualized.

    Depending on the availability of iodine, the thyroid gland is able to enhance or limit the use of iodine for thyroid hormone production. When compensation fails, as in severely iodine-deficient populations, hypothyroidism and developmental brain damage will be the dominating disorders. This is, out...... thyroid function by high levels of iodine is especially common in people affected by thyroid autoimmunity (Hashimoto's thyroiditis). In populations with high iodine intake, the average serum thyroid-stimulating hormone (TSH) tends to increase with age. This phenomenon is especially pronounced in Caucasian...

    Gangliosides are sialic acid-containing glycolipids which are formed by a hydrophobic portion, the ceramide, and a hydrophilic part, i.e. the oligosaccharide chain. First described in neural tissue, several studies have shown that gangliosides are almost ubiquitous molecules expressed in all vertebrate tissues. Within cells, gangliosides are usually associated with plasma membranes, where they can act as receptors for a variety of molecules and have been shown to take part in cell-to-cell interaction and in signal transduction. In addition, gangliosides are expressed in cytosol membranes like those of secretory granules of some endocrine cells (adrenal medulla, pancreatic islets). As far as the role of gangliosides in diseases is concerned, there are some cases in which an aberrant ganglioside expression plays a crucial role in the disease pathogenetic process. These diseases include two major forms of ganglioside storage, namely GM2-gangliosidosis (Tay-Sachs and its beta-hexosaminidase deficiency) and GM1-gangliosidosis (beta-galactosidase deficiency), where the most prominent pathological characteristic is the lysosomal ganglioside accumulation in neurons. Other inflammatory or degenerative diseases both within and outside the nervous system have been shown to be associated with an altered pattern of ganglioside expression in the target organ. Since monoclonal antibodies have been discovered and used in immunology, a large variety of ganglioside antigens has been described both as blood group antigens and as tumour-related antigens. Several studies have also indicated that gangliosides can act not only as antigens, but also as autoantigens. As a matter of fact, auto-antibodies to gangliosides, detected by immunostaining methods performed directly on TLC plates or by ELISA, have been described in several autoimmune disorders such as Guillain-Barré syndrome, multiple sclerosis, lupus erythematosus, Hashimoto's thyroiditis and, last but not least, insulin

The aim of this study was to investigate the prevalence of ADs in spondyloarthropathies (SpAs and vice versa. This was a two-phase cross-sectional study. First, we examined the presence of ADs in a cohort of patients with SpAs (N=148. Second, we searched for the presence of SpAs in a well-defined group of patients with ADs (N=1077 including rheumatoid arthritis (RA, systemic lupus erythematosus (SLE, and Sjögren’s syndrome (SS. Among patients with SpAs, ankylosing spondylitis was observed in the majority of them (55.6%. There were two patients presenting with SS in the SpA group (1.4% and 5 patients with autoimmune thyroiditis (3.5%. The global prevalence of ADs in SpAs was 4.86%. In the ADs group, there were 5 patients with SpAs (0.46%. Our results suggest a lack of association between SpAs and ADs. Accordingly, SpAs might correspond more to autoinflammatory diseases rather than to ADs.

     Autoimmune polyglandular syndrome (APS) is a combination of different autoimmune diseases. The close relationship between immune-mediated disorders makes it mandatory to perform serological screening periodically in order to avoid delayed diagnosis of additional autoimmune diseases. We studied a patient with type 1 diabetes (T1D) who later developed an autoimmune thyroid disease (ATD) and was referred to our hospital with a serious condition of his clinical status. The patient was suffering from an advance stage of celiac disease (CD), the delay in its diagnosis and in the establishment of a gluten-free dietled the patient to a severe proteincalorie malnutrition. Later, the patient developed an autoimmune hepatitis (AIH). We consider that clinical deterioration in patients with APS should alert physicians about the possible presence of other immune-mediated diseases. Periodic screening for autoantibodies would help to prevent delayed diagnosis and would improve patient's quality of life. PMID:27236159

    The pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) are basically characterized by obsessive-compulsive symptoms and/or tics triggered by group-A beta-hemolytic Streptococcus infections. Poor data are available about the clear definition of PANDAS's autoimmune origin. The aim of our study was to evaluate the prevalence of autoimmune phenomena, including thyroid function abnormalities, specific celiac disease antibodies, and positivity of organ- or nonorgan-specific autoantibodies in a large cohort of Caucasian children and adolescents with PANDAS. Seventy-seven consecutive patients (59 males, 18 females; mean age 6.3±2.5 years, range 2.0-14.5 years) strictly fulfilling the clinical criteria for PANDAS diagnosis were recruited. In all subjects we evaluated serum concentrations of free-T3, free-T4, thyrotropin, and the following auto-antibodies: anti-thyroperoxidase, anti-thyroglobulin, anti-thyrotropin receptor, anti-gliadin, anti-endomysium, anti-tissue transglutaminase, anti-nuclear, anti-smooth muscle, anti-extractable nuclear antigens, anti-phospholipid, plus lupus-like anticoagulant. The results were compared with those obtained from 197 age- and sex-matched healthy controls (130 males, 67 females; mean age 6.8±2.9 years, range 2.3-14.8 years). The frequencies of subclinical (3.8% vs 3.6%) and overt hypothyroidism (1.2% vs 0%), autoimmune thyroiditis (2.46% vs 1.14%), celiac disease (1.2% vs 0.05%), and positivity of organ- and nonorgan-specific autoantibodies (5.1% vs 4.8%) were not statistically significant between patients with PANDAS and controls. Evaluating the overall disease duration, we did not observe any significant difference between patients with (3.4±2.15 years) and without (3.4±2.89 years) autoimmune abnormalities. However, PANDAS patients with autoimmune diseases or positivity for any organ- and nonorgan-specific antibodies showed significantly higher anti-streptolysin O and anti-DNAse B

    Full Text Available Abstract Introduction Hyperthyroidism is a well established cause of atrial fibrillation (AF. Thyroid Stimulating Hormone-secreting pituitary tumours are rare causes of pituitary hyperthyroidism. Whilst pituitary causes of hyperthyroidism are much less common than primary thyroid pathology, establishing a clear aetiology is critical in minimising complications and providing appropriate treatment. Measuring Thyroid Stimulating Hormone (TSH alone to screen for hyperthyroidism may be insufficient to appropriately evaluate the thyroid status in such cases. Case presentation A 63-year-old Caucasian man, previously fit and well, presented with a five-day history of shortness of breath associated with wheeze and dry cough. He denied symptoms of hyperthyroidism and his family, social and past history were unremarkable. Initial investigation was in keeping with a diagnosis of atrial fibrillation (AF with fast ventricular response leading to cardiac decompensation. TSH 6.2 (Normal Range = 0.40 – 4.00 mU/L, Free T3 of 12.5 (4.00 – 6.8 pmol/L and Free T4 51(10–30 pmol/L. Heterophilic antibodies were ruled out. Testosterone was elevated at 43.10 (Normal range: 10.00 – 31.00 nmol/L with an elevated FSH, 18.1 (1.0–7.0 U/L and elevated LH, 12.4 (1.0–8.0 U/L. Growth Hormone, IGF-1 and prolactin were normal. MRI showed a 2.4 cm pituitary macroadenoma. Visual field tests showed a right inferotemporal defect. While awaiting neurosurgical removal of the tumour, the patient was commenced on antithyroid medication (carbimazole and maintained on this until successful trans-sphenoidal excision of the macroadenoma had been performed. AF persisted post-operatively, but was electrically cardioverted subsequently and he remains in sinus rhythm at twelve months follow-up off all treatment. Conclusion This case reiterates the need to evaluate thyroid function in all patients presenting with atrial fibrillation. TSH-secreting pituitary adenomas must be considered

    Full Text Available Objective. To study the rate and structure of thyroid diseases in infertile women and to asses their reproductive system depending upon the thyroid pathology. Subjects and methods. The study was based on the results of screening of T status of 496 women with infertility (main group and 80 fertile women (control group. Traditional methods of diagnosis of infertility were used along with special methods of investigation including assessment of function and structure of T (TTH, fT4, fT3, AT-TPO, AT-rTTH, ultrasound examination of T, thin-niddle aspirational biopsy, scintigraphy of T. A complex evaluation of the reproductive system status in infertile women was done depending on the type of T pathology. Results. Infertile women were found to suffer from thyroid dysfunction 3.8 times as more often as fertile ones (48% and 12.5%, p <0.05. Its structure included mainly AT-TPO carrier phenomenon in combination with ultrasound markers of thyroid autoimmunity (24%, hypothyroidism following thyroid autoimmunity (9.4% demonstrating itself as clinical (0.8%, subclinical (8.6%, and euthyroid (7.8% goiters. The portion of women with infertility and hyperthyroidism was small (0.6%. An association of thyroid autoimmunity with idiopathic infertility, endometriosis, endocrine infertility was found. Conclusion. It is necessary to perform a screening assessment of the function and structure of T in infertile women within diagnostic search for the reasons of infertility and in-time correction of the revealed thyroid dysfunction.

    Full Text Available The paper reported on a case of severe myoclonic epilepsy of infancy (SMEI associated with a probable autoimmune lymphoproliferative syndrome variant (Dianzani autoimmune lymphoproliferative disease (DALD. A male patient with typical features of SMEI and a SCN1A gene variant presented in the first year of life with multiple lymph nodes, palpable liver at 2 cm from the costal margin, neutropenia, dysgammaglobulinemia, relative and sometimes absolute lymphocytosis. Subsequently the patient presented with constantly raised IgA in serum and positive antinuclear and thyroid antimicrosomal antibodies. The diagnosis of probable autoimmune lymphoproliferative syndrome was made; arthritis, skin and throat blisters, which appeared subsequently led to the diagnosis of linear IgA disease. On the basis of these unique associations, the Authors hypothesized that autoimmunity may be partly responsible of the severe epileptic symptomatology, perhaps mediated by autoantibodies against sodium channels or by accompanying cytotoxic T-lymphocytes. Corticosteroid treatment ameliorated the epilepsy and laboratory tests. Future studies will be necessary to evaluate the relevance of autoimmunity in SMEI.

  9. Thyroid disorders in atomic-bomb survivors

    International Nuclear Information System (INIS)

    It is known from several studies, including those from RERF that radiation exposure can cause thyroid tumors (Socolow, N Engl J Med. 1963;268:406, Parker, Ann Intern Med. 1974;80:600). Effects of radiation on autoimmune thyroid disease are not well understood. We have conducted thyroid disease screening on a population of 2856 individuals from the Adult Health Study (AHS) cohort of atomic-bomb survivors for the period of 1984-1987. This study, which for logistical reasons involved survivors only from Nagasaki, revealed a statistically significant relationship between radiation dose and prevalence of solid nodules, including cancer, and that of autoimmune hypothyroidism (Nagataki, JAMA. 1994;272:364). Because the previous thyroid study was conducted only in Nagasaki, the new comprehensive thyroid disease screening study has been ongoing in Hiroshima and Nagasaki AHS participants since March 2000. For about 4,000 participants in Hiroshima and Nagasaki AHS cohort, thyroid ultrasonography, aspiration biopsy of nodules, thyroid function test, thyroid autoantibody (thyroid peroxidase antibody and thyroglobulin antibody) test by highly sensitive assay using enzyme linked immunosorbent assay were performed for the diagnosis of thyroid diseases. Analysis of data from the 1874 people examined through July 2001 (915 people from Hiroshima, 959 people from Nagasaki) provides evidence that thyroid cancer increases with radiation dose. The prevalence of positive result for thyroid autoantibody test is increased in the people exposed to relative low dose of radiation (0.01-0.99 Sv). Examination and measurements was completed in February 2003 for all patients. The analysis of these data is providing new and more complete insights into relationships between thyroid diseases and low doses of radiation

    2002-08-01

    Addison's disease has a low incidence and is most frequently the result of an autoimmune disease in developed countries. Addison's disease can present as an isolated entity or in combination with other autoimmune diseases: Addison's disease can be part of the distinct polyglandular autoimmune syndromes APS I and II. Autoantibodies in patients with isolated Addison's disease are directed against the enzymes involved in steroid synthesis, P45oc21, P45oscc and P45oc17. Addison's disease, both isolated and in the context of APS II, has been associated with the haplotype HLA-A1, -B8 and DR3. The value of the increased expression of these molecules on adrenocortical cells could point towards an infectious pathogenesis. Given the prevalence, up to 80 %, of autoantibodies in Addison's disease as well as the high predictive value for developing the disease when antibodies are present (41% in three years), we advise screening high-risk populations, such as patients with other autoimmune endocrinopathies or their relatives for the presence of these antibodies. The adrenocortical function of patients positive for antibodies should be followed yearly. PMID:12430572

    Full Text Available We report the first patient with subacute thyroiditis after influenza vaccination in Japan. A 49-year-old woman received a seasonal influenza vaccination in October 2009. She also received a seasonal influenza vaccination in 2008. After the vaccination, she experienced spontaneous pain and tenderness in the right lower neck. Together with the results of laboratory examinations and thyroid echography, we established the diagnosis of subacute thyroiditis. The patient had human leukocyte antigens (HLAs of A2/A11 and B62/B35. HLA-A2-positive is reported at a risk of interferon-alpha-induced autoimmune thyroid disorder, and HLA-B35-positive is reported at a risk of subacute thyroiditis. Since fever and cervical pain are reported as adverse effects of influenza vaccination, subacute thyroiditis after influenza vaccination might have been missed.

    2008-06-01

    Full Text Available Liver disorders with a likely autoimmune pathogenesis in childhood include autoimmune hepatitis (AIH, autoimmune sclerosing cholangitis (ASC, and de novo AIH after liver transplantation. AIH is divided into two subtypes according to seropositivity for smooth muscle and/or antinuclear antibody (SMA/ANA, type 1 or liver kidney microsomal antibody (LKM1, type 2. There is a female predominance in both. LKM1 positive patients tend to present more acutely, at a younger age, and commonly have partial IgA deficiency, while duration of symptoms before diagnosis, clinical signs, family history of autoimmunity, presence of associated autoimmune disorders, response to treatment, and long-term prognosis are similar in both groups. The most common type of paediatric sclerosing cholangitis is ASC. The clinical, biochemical, immunological, and histological presentation of ASC is often indistinguishable from that of AIH type 1. In both, there are high IgG, non-organ specific autoantibodies, and interface hepatitis. Diagnosis is made by cholangiography. Children with ASC respond to immunosuppression satisfactorily and similarly to AIH in respect to remission and relapse rates, times to normalization of biochemical parameters, and decreased inflammatory activity on follow up liver biopsies. However, the cholangiopathy can progress. There may be evolution from AIH to ASC over the years, despite treatment. De novo AIH after liver transplantation affects patients not transplanted for autoimmune disorders and is strikingly reminiscent of classical AIH, including elevated titres of serum antibodies, hypergammaglobulinaemia, and histological findings of interface hepatitis, bridging fibrosis, and collapse. Like classical AIH, it responds to treatment with prednisolone and azathioprine. De novo AIH post liver transplantation may derive from interference by calcineurin inhibitors with the intrathymic physiological mechanisms of T-cell maturation and selection. Whether

    Differentiated thyroid carcinoma was studied with regard to mode of presentation, initial findings, treatment and survival. The classic signs, symptoms, physical and scan findings were found to be present in approximately 70% of the patients. Prognosis was found to be dependent on age of presentation more than any other factor. Patients with prior exposure to radiation were found to have more extensive disease and require more extensive surgery but ultimately had the same prognosis for 15-year cure. Treatment for distant metastatic disease by surgery, radioactive iodine and external radiation all resulted in long-term survival in certain cases

  3. Dual thyroid ectopia-role of thyroid scintigraphy and neck ultrasonography

    International Nuclear Information System (INIS)

    Ectopic thyroid tissue (ETT) is a rare developmental anomaly of the thyroid tissue where the thyroid gland is not located in its usual position. Dual thyroid ectopia is far rarer. This case of a 5-year-old euthyroid girl with thyroglossal cyst was planned for surgery. Presurgical ultrasonography (USG) of the neck followed by thyroid scintigraphy was performed. There was absent normal thyroid gland with single ETT in neck swelling on USG. However, thyroid scintigraphy revealed two ectopic foci of thyroid tissue; one was corresponding to neck swelling, and other was superior to it at the base of the tongue along with absent eutopic thyroid gland. The repeat neck USG could demonstrate the same. The present case emphasizes that, if the thyroid gland is not visible by USG; ETT should be evaluated with thyroid scintigraphy in case of thyroid dysgenesis

Aim: The purpose of our study was to immunophenotype selected APC in the lesional skin of ABDs, utilizing immunohistochemistry (IHC stains. Materials and Methods: We utilized IHC to stain for dendritic cells (DC, staining with CD1a, CD68, HAM56, and S-100 in lesional skin from 30 patients with endemic pemphigus foliaceus (EPF, 15 controls from the EPF endemic area, and 15 healthy controls from the USA. We also tested archival biopsies from patients with selected ABD, including 30 patients with bullous pemphigoid (BP, 20 with pemphigus vulgaris (PV, 8 with pemphigus foliaceus (PF and 14 with dermatitis herpetiformis (DH and 2 with epidermolysis bullosa acquisita (EBA. Results: Cells stained by CD68, HAM56 and S-100 were present in the majority of the ABD skin biopsies; these cells were located primarily in perivascular infiltrates surrounding dermal vessels subjacent to the blisters. However, these cells were also noted within the blisters, in vessels supplying dermal eccrine glands and ducts, and in areas of dermal endothelial-mesenchymal cell junction-like structures, especially in BP cases. In our CD1a staining, the number and location of positive staining cells varied with each disease, being abundant in most ABD in the epidermis suprajacent to the blisters, or in the epidermis surrounding the blister site if the blister site epidermis was missing. In the control biopsies, most did not display positive IHC staining, with the exception of a few CD1a positive cells in the epidermis Conclusion: Our findings confirm positive IHC staining for APCs in areas of the skin besides the disease blisters. Our findings suggest that the antigen presentation in ABD proceeds in areas distant from the blister site

    In-vitro evidence suggests that DNA methylation may be involved in the development of forbidden immune responses that can result in autoimmune disease. In the present study we examined in-vivo effects of 5-azacytidine (5-azaC), a substance that inhibits DNA methylation, on the immune system and the occurrence of a spontaneous autoimmune disease in the chicken model. We found that (1) treatment of young normal chickens with 1.0 mg/kg 5-azaC on 7 consecutive days caused a rapid degeneration of the central lymphoid organs thymus and bursa; (2) this regimen with 5-azaC apparently inhibited B cell maturation, as the frequency of cytoplasmic Ig+ plasma cells in the bone marrow was found to be significantly reduced, whereas the total number of bone marrow cells was unchanged; and (3) a chronic low-dose (0.5 and 1.0 mg/kg) application of 5-azaC through 6 weeks was found to significantly enhance the spontaneous autoimmune thyroiditis in newly hatched chickens of the Cornell C strain, as determined by anti-thyroglobulin autoantibody titres and histological analysis of thyroid gland infiltration. The possible implications of these data for the generation of pathogenic autoimmune responses are discussed. Images Fig. 1 PMID:1726865

  10. Thyroid ophthalmopathy revisited

    International Nuclear Information System (INIS)

    Thyroid ophthalmopathy is an autoimmune orbital disorder closely associated with Graves' disease, although both conditions may also occur isolatedly. Thyroid ophthalmopathy may precede, coincide or follow the thyroid dysfunction onset and may rarely occur in euthyroid and hypothyroid patients. The extra ocular muscles are most frequently involved and become enlarged resulting in ophthalmoplegia and proptosis. Other relevant signs include palpebral retraction, conjunctival hyperemia and periorbitary edema. Visual loss may occur in association with compressive optic neuropathy at the orbital apex. Thyroid ophthalmopathy is characterized by inflammation, congestion, hypertrophy and fibrosis involving fat and the orbital muscles. The disease activity is divided into two phases: an acute or inflammatory phase and a second one corresponding to an inactive phase associated with fibrotic changes and fat infiltration of the retrobulbar tissues. The diagnosis is based on clinical findings and imaging methods are indicated in case of doubt or suspicion of optic neuropathy. Computed tomography and magnetic resonance imaging can confirm the diagnosis, allowing the evaluation of the critical region of the orbital apex. Magnetic resonance imaging is the method of choice considering the superior tissue contrast resolution, besides the capacity of evaluating the disease activity by means of long TR sequences and detecting inflammatory changes, with a relevant role in a timely therapeutic planning, which may improve the prognosis.

    associated with such adaptation leads to thyroid growth, and during follicular cell proliferation there is a tendency to mutations leading to multifocal autonomous growth and function. In populations with mild and moderate iodine deficiency, such multifocal autonomous thyroid function is a common cause of...... thyroid function by high levels of iodine is especially common in people affected by thyroid autoimmunity (Hashimoto's thyroiditis). In populations with high iodine intake, the average serum thyroid-stimulating hormone (TSH) tends to increase with age. This phenomenon is especially pronounced in Caucasian......Depending on the availability of iodine, the thyroid gland is able to enhance or limit the use of iodine for thyroid hormone production. When compensation fails, as in severely iodine-deficient populations, hypothyroidism and developmental brain damage will be the dominating disorders. This is, out...

    Full Text Available Myasthenia gravis (MG may occur in association with other organ- specific or nonspecific autoimmune diseases. In our study, we present a patient with ocular myasthenia, Hashimoto’s thyroiditis, and iron deficiency anemia who later developed reactive hypoglycemia. A 25-year-old woman with complaints of fluctuating extraocular muscle weakness, ptosis, and diplopia was examined. MG, type I (ocular MG, was confirmed by an elevated titer of anti-acetylcholine receptor antibodies in serum (7 nmol/l, normal <0.6 and positive edrophonium test. Nerve conduction studies, needle electromyography, repetitive stimulation tests, and mediasten MRI were normal. The coexistence of Hashimoto's thyroiditis was diagnosed by the presence of a diffuse thyroid enlargement, elevated titers of anti-thyroglobulin antibodies (211.8 IU/ml, normal 0-115, thyroid peroxidase antibodies (356.4 IU/ml, normal 0-34, thyroid stimulating hormone (8.21 uIU/ml, normal 0.27-4.2, and a decreased titer of free-T4 (1.03ng/dl normal 1.8-4.6. Diplopia and ptosis have regressed with 180 mg/day pyridostigmine bromide. On her follow-up period, 8 months later, reactive hypoglycemia has been diagnosed. The coexistence of myastenia gravis, Hashimoto’s thyroiditis and reactive hypoglycemia was not found in the literature. We should take into consideration the association and the importance of recognizing and treating these pathologies in myastenia gravis. Turk Jem 2009; 13: 31-3

    Although autoimmune diseases exhibit contrasting epidemiological features, pathology, and clinical manifestations, three lines of evidence demonstrate that these diseases share similar immunogenetic mechanisms (that is, autoimmune tautology). First, clinical evidence highlights the co-occurrence of distinct autoimmune diseases within an individual (that is, polyautoimmunity) and within members of a nuclear family (that is, familial autoimmunity). Second, physiopathologic evidence indicates th...

    Full Text Available The focus of the present review article is on thyroid dysfunctions which can be hypo or hyper thyroidism. Along with the ongoing allopathic treatment options, one can go for the alternative therapies or natural cures. Various nutritional supplements including iodine, botanicals like guggul and many more play an effective role in the management of thyroid dysfunction apart from the pharmaceuticals like synthetic T3 and T4 hormones and procaine thyroid. Along with these, homeopathy and yoga are equally important. The discussion suggests and emphasizes the importance of improving the lifestyle and nutritional diet; and further providing spiritual support along with natural thyroid medication.

It typically occurs in females due to anautoimmune phenomenon to endogenous progesterone production, but can also be caused byexogenous intake of a synthetic progestin. Here in, we present a case of autoimmune progesterone anaphylaxis (AIPA observed in an adolescent female.The patient is an 18-year-old Caucasian female with no significant past medical history and noprior exogenous hormone use, who presented to her primary care physician complaining of cyclic skin eruptions with dyspnea, cough and respiratory distress. She noted that her symptoms occurred monthly, just prior to her menses. An intradermal skin test using 0.1 cml of progesterone was performed. The patient developed a 15mm wheal after 15 minutes, confirming the diagnosis of AIPA.The patient was started on a continuous regimen of an oral conjugated estrogen (0.625mg. The skin eruptions and respiratory symptoms have not returned since the initiation of this therapy.Autoimmune progesterone dermatitis manifests via the occurrence of cyclic skin eruptions.Women with the disorder commonly present with dermatologic lesions in the luteal phase of themenstrual cycle, if there are any other organ involvement in addition to skin (e.g. lung, GI thereaction should be called as autoimmune progesterone anaphylaxis. Diagnosis of AIPA is confirmed by performing a skin allergen test using progesterone.

    Full Text Available Autoimmune polyglandular syndrome is a polyendocrinopathy characterized by failureof some endocrine glands as well as nonendocrine organs, caused by actions of theimmune system on endocrine tissues. It has been described two groups and at leasttwo or three variants of them. Autoimmune polyglandular autoimmune syndrome typeII is the most common autoimmune endocrinopathy that is characterized mainly bypresence of Addison’s disease in combination with autoimmune thyroid disease or typeI diabetes mellitus. We review the topic and immunogenetics and etiopathological basesand present a case series. The incidence is 1.2/100.000. The most common finding wasAddison’s disease plus autoimmune thyroiditis (80% and the second most frequentassociation was thyroiditis with pernicious anemia (60%. It is important to note thehigh frequency of vitamin B12 deficiency in patients with severe neuronal impairment. Itmay take up to twenty years between diagnosis of an endocrine disease and emergenceof another disease. It is the duty to perform diagnostic tests to evaluate hormonalfunction correlated with an endocrinopathy until senescence.RESUMEN:El Síndrome Poliglandular Autoinmune es una poliendocrinopatía caracterizada porfalla de algunas glándulas endocrinas así como también en órganos no endocrinos,originada por acciones del sistema inmune sobre tejidos endocrinos.

    Background Race, gender and socioeconomic disparities have been suggested to adversely influence stage at presentation, treatment options and outcomes in patients with cancer. Underserved minorities and those with a low socioeconomic status (SES) present with more advanced disease and have worse outcomes for differentiated thyroid cancer, but this relationship has never been evaluated for medullary thyroid cancer (MTC). Methods We used the California Cancer Registry (CCR) to evaluate disparities in the presentation, treatment and outcomes of patients diagnosed with MTC. Results We identified 634 patients with MTC diagnosed between 1988 and 2011. Almost everyone (85%) underwent thyroidectomy with 50% having a central lymph node dissection (CLND). There were no statistically significant differences by age, race or SES in mean tumor size or the proportion of patients diagnosed with localized disease, but men were diagnosed with larger tumors than women and were less likely to be diagnosed at a localized stage. Younger patients and women were more likely to be treated with a thyroidectomy. There were no statistically significant differences in surgical treatment by race or SES. Patients in the highest SES category had a better overall survival, but not disease specific survival, than those in the lowest SES (HR =0.3, CI =0.1–0.7). Patients treated with thyroidectomy had a better overall and cause specific survival, but the effect of CLND was not statistically significant after adjustment for other factors. Conclusions In MTC, we did not find that race, gender or SES influenced the presentation, treatment or outcomes of patients with MTC. Men with MTC present with larger tumors and are less likely to have localized disease. Half of the MTC patients in California do not undergo a CLND at the time of thyroidectomy, which may suggest a lack appropriate care across a range of healthcare systems. PMID:27563561

    The authors recently reported the occurrence of low fasting serum triglyceride (TG) and high free fatty acid (FFA) levels in idiopathic pulmonary fibrosis. TG estimation in diverse groups of patients with autoimmune disease or hyperactive immune response confirmed the occurrence of a similar decrease of TG. In some patients, serum FFA level was also evaluated. TG value in lean and obese patients was compared with that in lean (n = 108) and obese (n = 208) control subjects without autoimmune disease. In patients affected by autoimmune chronic thyroiditis with enhanced concentration of antithyroglobulin antibodies and without thyroidal failure (n = 24), lean and obese patients had reduced TG (-69/%, P autoimmune diseases (scleroderma, APECED [autoimmune polyendocrinopathy, candidiasis, and ectodermal dystrophy], urticaria or urticarial vasculitis, Reiter or Sjogren syndromes, ulcerative colitis or Crohn's disease, multiple sclerosis or Guillain-Barré syndrome) (n = 14), decreased TG was also observed both in the lean and obese subjects (-59%, P autoimmunity or immune system hyperreactivity.

    The thyroid glands are a vulnerable organ to ionizing radiation. Indeed the epidemiological studies have revealed an increase in the incidences of thyroid cancer among atomic bomb survivors in Hiroshima and Nagasaki and radiation casualties in Chernobyl. The carcinogenic risk for the thyroids is dependent on radiation dose, and higher in younger people. Recent advances in molecular biology contribute to clarify the mechanisms for thyroid carcinogenesis at genetic and molecular levels. Here radiation-induced thyroid carcinogenesis is reviewed from epidemiological data to basic research. PMID:22514922

    Full Text Available Background: Thyroid disorders are common endocrine disorders encountered in the African continent. Environmental and nutritional factors are often implicated in the occurrence of some thyroid disorders that occur in this part of the world. This is a narrative review that seeks to document the pattern, prevalence, and management of thyroid disorders in the continent. Materials and Methods: The search engine used for this review were PubMed and Google scholar. All available articles on thyroid disorders from the sub-African continent, published until May 2011, were included. Results: Iodine deficiency disorders (IDD which top the list of thyroid disorders and remain the commonest cause of thyroid disorders in the continent is often affected not only by the iodine status in the region but sometimes also by selenium deficiency and thiocyanate toxicity. The reported prevalence rates of endemic goiter range from 1% to 90% depending on the area of study with myxedematous cretinism still a prominent feature of IDD in only a few regions of the continent. The extent of autoimmune thyroid disorders remains unknown because of underdiagnosis and underreporting but the few available studies note a prevalence rate of 1.2% to 9.9% of which Graves diseases is the commonest of these groups of disorders. Rarer causes of thyroid dysfunction such as thyroid tuberculosis and amiodarone related causes are also documented in this review. The onset of new thyroid diseases following amiodarone usage was documented in 27.6% of persons treated for arrhythmia. Reports on thyroid malignancies (CA in Africa abound and differentiated thyroid malignancies are noted to occur more commonly than the other forms of thyroid CA. The documented prevalence rates of thyroid CA in the African continent are as follows (papillary: 6.7-72.1%, follicular: 4.9-68%, anaplastic: 5-21.4%, and medullary: 2.6%-13.8%. For the differentiated thyroid CA, there is a changing trend toward the more

  11. Etiopathogenesis of Insulin Autoimmunity

    Full Text Available Autoimmunity against pancreatic islet beta cells is strongly associated with proinsulin, insulin, or both. The insulin autoreactivity is particularly pronounced in children with young age at onset of type 1 diabetes. Possible mechanisms for (proinsulin autoimmunity may involve beta-cell destruction resulting in proinsulin peptide presentation on HLA-DR-DQ Class II molecules in pancreatic draining lymphnodes. Recent data on proinsulin peptide binding to type 1 diabetes-associated HLA-DQ2 and -DQ8 is reviewed and illustrated by molecular modeling. The importance of the cellular immune reaction involving cytotoxic CD8-positive T cells to kill beta cells through Class I MHC is discussed along with speculations of the possible role of B lymphocytes in presenting the proinsulin autoantigen over and over again through insulin-carrying insulin autoantibodies. In contrast to autoantibodies against other islet autoantigens such as GAD65, IA-2, and ZnT8 transporters, it has not been possible yet to standardize the insulin autoantibody test. As islet autoantibodies predict type 1 diabetes, it is imperative to clarify the mechanisms of insulin autoimmunity.

    Full Text Available Metastasis to the thyroid gland is very rare. Recently, we experienced a case of thyroid metastasis from breast cancer accompanying a papillary thyroid. A 51-year-old female patient presented with a palpated lymph node on her left lateral neck. The patient had undergone a left modified radical mastectomy followed by chemotherapy and hormonal therapy 12 years prior. Ultrasonography of the neck revealed a malignant looking nodule at the left thyroid lobe, measuring 0.9 × 0.9 cm, and several cystic nodules at the right thyroid lobe. Ultrasonography of the neck additionally revealed a malignant looking lymph node at the right level VI. Fine-needle aspiration of the left thyroid lobe resulted in a diagnosis of papillary thyroid carcinoma and that of the right level VI in Hurthle cell lesion. The patient had a total thyroidectomy with selective dissection of the left neck node. Pathologic assessment of the specimen revealed metastatic carcinoma from the breast carcinoma and papillary thyroid carcinoma. Although the thyroid gland is highly vascularized, metastasis of malignant tumors to the thyroid is relatively rare and detection of metastasis shows a low frequency. So a careful evaluation of thyroid tumor should be considered in a patient with a history of other malignancy.

    Full Text Available Abstract Q fever is a worldwide zoonotic infection that caused by Coxiella burnetii, a strict intracellular bacterium. It may be manifested by some of the autoimmune events and is classified into acute and chronic forms. The most frequent clinical manifestation of acute form is a self-limited febrile illness which is associated with severe headache, muscle ache, arthralgia and cough. Meningoencephalitis, thyroiditis, pericarditis, myocarditis, mesenteric lymphadenopathy, hemolytic anemia, and nephritis are rare manifestations. Here we present a case of acute Q fever together with Coombs’ positive autoimmune hemolytic anemia (AIHA and tubulointerstitial nephritis treated with chlarithromycin, steroids and hemodialysis. Clinicians should be aware of such rare manifestations of the disease.

    Reactive oxygen species (ROS) have been extensively studied in the induction of inflammation and tissue damage, especially as it relates to aging. In more recent years, ROS have been implicated in the pathogenesis of autoimmune diseases. Here, ROS accumulation leads to apoptosis and autoantigen structural changes that result in novel specificities. ROS have been implicated not only in the initiation of the autoimmune response but also in its amplification and spreading to novel epitopes, through the unmasking of cryptic determinants. This review will examine the contribution of ROS to the pathogenesis of four organ specific autoimmune diseases (Hashimoto thyroiditis, inflammatory bowel disease, multiple sclerosis, and vitiligo), and compare it to that of a better characterized systemic autoimmune disease (rheumatoid arthritis). It will also discuss tobacco smoking as an environmental factor endowed with both pro-oxidant and anti-oxidant properties, thus capable of differentially modulating the autoimmune response.

    Background: Thyroid peroxidase (TPO) is a dimeric membrane-bound enzyme of thyroid follicular cells, responsible for thyroid hormone biosynthesis. TPO is also a common target antigen in autoimmune thyroid disease (AITD). With two active sites, TPO is an unusual enzyme, and thus there is much interest in understanding its structure and role in AITD. Homology modeling has shown TPO to be composed of different structural modules, as well as a propeptide sequence. During the course of studies to ...

    2008-09-01

    Autoantibodies play a key role in diagnostic laboratories as markers of autoimmune diseases. In addition to their role as markers they mediate diverse effects in vivo. Autoantibodies with protective effect have been described. Natural protective IgM autoantibodies against tumour-antigens of malignant cells or their precursors may contribute to increased survival rates of carcinoma patients. In a mouse model of systemic lupus erythematosus it has been shown that anti-dsDNA IgM autoantibodies protect from glomerular damage. In contrast, a direct pathogenic role of autoantibodies has been well established e.g. in myasthenia gravis or in Goodpasture syndrome. Similarly autoantibodies against SSA Ro52 are detrimental in neonatal lupus erythematosus with congenital heart block. Moreover, putatively protective autoantibodies may become pathogenic during the course of the disease such as the onconeuronal autoantibodies whose pathogenicity depends on their compartmentalisation. In patients with paraneoplastic syndromes tumour cells express proteins that are also naturally present in the brain. Anti-tumour autoantibodies which temporarily suppress tumour growth can provoke an autoimmune attack on neurons once having crossed the blood-brain barrier and cause specific neurological symptoms. Only a restricted number of autoantibodies are useful follow-up markers for the effectiveness of treatment in autoimmune diseases. Certain autoantibodies hold prognostic value and appear years or even decades before the diagnosis of disease such as the antimitochondrial antibodies in primary biliary cirrhosis or anti-citrullinated protein (CCP)-antibodies in rheumatoid arthritis. It is crucial to know whether the autoantibodies in question recognise linear or conformational epitopes in order to choose the appropriate detection methods. Indirect immunofluorescence microscopy remains a very useful tool for confirmation of results of commercially available immunoassays and for detection of

    Full Text Available 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 0.5cm 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 99mTc 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 oncocytic 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.

    The present study was designed to analyse the scintigraphic appearance of the thyroid in hypothyroid patients with blocking-type TSH receptor antibodies (TRAbs). Eleven hypothyroid patients with autoimmune thyroiditis positive for TSH binding inhibitor immunoglobulins (TBII) [80% [+-] 12 (SD)%; normal <11%] and for thyroid stimulation-blocking antibodies (TSBAbs) (90% [+-] 9%; normal <32%) were studied. Thyroid scanning was performed using technetium-99m or iodine-123, when the patients were hypothyroid. Analysis of the scan images revealed the presence of localized functioning areas in six patients (group 1), and no visualization of the thyroid in the remaining five patients (group 2). Patients in group 1 showed significantly higher uptake of [sup 99m]Tc than those in group 2 (P<0.05). Interestingly, three patients in group 1 were positive for thyroid-stimulating antibodies (TSAbs) (249% [+-] 17%; normal <145%), which were not detected in the remaining eight patients. Antibodies against thyroglobulin and microsomal antigens were detected in nine (81.8%) and 11 (100%) patients, respectively, but neither of these titres correlated with the scan image. Three patients in group 1 underwent scintigraphy again after treatment with thyroxine, at which time the functioning lesion was not noted. Fourteen hypothyroid patients with negative TBII displayed no such scintigraphic findings. Chronic stimulation of the thyroid by TSAbs and/or TSH might be responsible for the presence of the functioning lesion, but clarification of the mechanism requires further studies. In summary (1) TSAbs were detected in three (27.3%) of 11 hypothyroid patients with blocking TRAbs; (2) thyroid scintigraphy revealed the presence of localized functioning area(s) in approximately half of these cases.

  7. Ectopic lingual thyroid

    International Nuclear Information System (INIS)

    Thyroid ectopy is characterized by the presence of thyroid tissue outside its normal position resulting from a defect of the thyroid diverticulum migration from the base of the tongue until its final pre-tracheal position. One case is presented in a 12-year-old girl patient who consults for a failure to thrive estimated at less than three standard deviations (SD). Bone age was estimated at 8 years late compared to chronological age. The hormonal assessment showed hypothyroidism with negative thyroid antibodies. Cervical ultrasound was revealed thyroid parenchyma pre-dominantly left in place while sweeping the area under chin showed a nodular formation of the base of the tongue. Thyroid scan with technetium 99 m showed a selective uptake of radiotracer in sublingual position. Cervical computed tomography revealed a posterior median sublingual mass spontaneously hyperdense and enhancing sharply after injection of contrast. Treatment with thyroxine allowed obtaining euthyroidism. This case asks us to be careful before aetiological diagnosis of hypothyroidism in children, because although this is rare, the presence of a thyroid parenchyma up to the cervical ultrasound does not eliminate the presence of ectopic tissue

    Asymptomatic chronic thyroiditis (ACT) is a variant of the autoimmune thyroiditis characterized by the presence of circulating anti-thyroid antibodies and the absence of palpable goiter. Thyroid function can be normal but a considerable percentage of ACT patients tend to develop subclinical hypothyroidism over time and thus periodical controls of thyroid hormones and TSH levels are needed. At present, useful parameters for predicting the functional out-came of ACT patients are lacking. To investigate this aspect, the authors evaluated 57 consecutive ACT patients (51 females, 6 males, aged 22-56 years) by means of thyroid {sup 99m}Tc-pertechnetate scintigraphy and echography, and by measuring the serum level of anti-peroxidase antibodies (TPOAbs), FT4, T3 and TSH. At first observation, 30 patients were euthyroid whereas 27 had subclinical hypothyroidism. No patient had been previously treated with thyroid hormones. Thyroid scan showed a normal pattern or a diffuse and mild irregular uptake, without differences between euthyroid and subclinical hypothyroid patients. TPOAb levels tend to be higher in patients with subclinical hypothyroidism in comparison to the euthyroid patients (5893{+-}1423 and 3943{+-}912 UI/mL, respectively) but the difference was not statistically significant by using Student`s {sup t-}test. Echography showed a normal pattern in 14 patients, while a diffuse hypoechoic pattern in the other cases, mild in 12, moderate in 19 and marked in 12, as found. A significantly higher prevalence of subclinical hypothyroidism was observed in the group of patients with a moderate or marked hypoechoic pattern in comparison to the group with a normo-echoic or mild hypoechoic pattern (70.4% versus 23.0%, Fisher`s exact test p=0.00003). Furthermore, the 3 patients who developed thyroid failure during a one-year follow-up also presented a moderate or marked hypoechoic pattern. (Abstract Truncated)

    Full Text Available A 71-year-old woman with severe right lower leg pain, edema and erythema was presented to the Emergency Department and was found to have an extensive deep vein thrombosis (DVT confirmed by ultrasound. She underwent an extensive evaluation due to her prior history of malignancy and new hypercoagulable state, but no evidence of recurrent disease was detected. Further investigation revealed pernicious anemia (PA, confirmed by the presence of a macrocytic anemia (MCV=115.8fL/red cell, Hgb=9.0g/dL, decreased serum B12 levels (56pg/mL, with resultant increased methylmalonic acid (5303nmol/L and hyperhomocysteinemia (131μmol/L, the presumed etiology of the DVT. The patient also suffered from autoimmune thyroid disease (AITD, and both antithyroglobulin and anti-intrinsic factor antibodies were detected. She responded briskly to anticoagulation with heparin and coumadin and treatment of PA with intramuscular vitamin B12 injections. Our case suggests that a DVT secondary to hyperhomocystenemia may represent the first sign of polyglandular autoimmune syndrome III-B (PAS III-B, defined as the coexistent autoimmune conditions AITD and PA. It is important to recognize this clinical entity, as patients may not only require acute treatment with vitamin B12 supplementation and prolonged anticoagulation, as in this patient, but may also harbor other autoimmune diseases.

    Full Text Available Background: To evaluate the involvement of immune abnormality in patients with idiopathic premature ovarian insufficiency (POI. In addition to the known etiology, autoimmune disorders may be a pathologic mechanism for POI. Materials and Methods: Our study was a prospective controlled trial. Twenty women with POI, reasons other than autoimmune excluded, were enrolled in this study. The control group consisted of 17 healthy women. In both groups, family and personal history were taken and the levels of follicle stimulating hormone, luteinizing hormone, thyroid-stimulating hormone, prolactin, anti-Müllerian hormone, inhibin B, antithyroglobulin and antithyroid peroxidase antibodies were determined. Antiovarian antibodies and subpopulations of peripheral blood T-lymhocytes were also determined. Results: Participants in the study group exhibited hypergonadotropichypogonadism, while high levels of follicle stimulating hormone and low levels of inhibin B and anti- Müllerian hormone were observed. In 16 (80% patients, POI was associated in their personal and familial history with another autoimmune disease. Fifty percent of patients presented highly elevated antithyroid antibodies. The lymphocyte subset, especially B cells, was significantly higher (p=0.014, and peripheral regulatory lymphocytes CD25+ high were significantly lower (p=0.015 in the study group than in the control group. Antiovarian antibodies were detected in 20% of patients with POI. Conclusion: We presume that the presence of anti-ovarian antibodies together with abnormalities of cellular immunity may in some cases potentially represent the involvement of an autoimmune mechanism in idiopathic POI.

It may be part of the physiological immune response (natural autoimmunity or pathologically induced, which may eventually lead to development of clinical abnormalities (autoimmune disease. Different mechanisms are involved in the induction and progression of autoimmunity. These include genetic or acquired defects in immune tolerance or immune regulatory pathways, molecular mimicry to viral or bacterial protein, an impaired clearance of apoptotic cell material. A A number of diseases have been identified in which there is autoimmunity, due to copious production of autoantibodies and autoreactive cells. The aim of the present article is to review on the pathogenesis of autoimmune diseases.

    They're useful in diagnosing Graves' disease and, to a lesser extent, autoimmune thyroid disease; they can also help predict hypothyroidism. Thyrotropin receptor antibodies (TRAb) may be mildly elevated in a variety of thyroid disorders, but a TRAb level >10 U/L increases the probability of Graves' disease by a moderate to large degree (strength of recommendation [SOR]: cross-sectional study). A positive or negative thyroid peroxidase antibody (TPOAb) test increases or decreases the probability of autoimmune thyroid disease by only a small to moderate degree (SOR: 3 cross-sectional studies). Thyroid-stimulating hormone (TSH) levels >2 mU/L, although still in the normal range, can be followed up with TPOAb testing to determine whether the patient has an increased probability of developing hypothyroidism (SOR: cohort study with a vague hypothyroidism reference standard).

    Five patients, four brothers and their paternal aunt, presented with a history of overt hyperthyroidism and goiter. Hyperthyroidism in this family was remarkable for its poor response to carbimazole (30–50 mg/d). The thyroid ultrasound showed a diffusely enlarged gland in all the affected members, and thyroid stimulating antibodies (TSAB) were negative. Screening for germline mutations in thyroid stimulating hormone (TSH) receptor (TSHR) gene was performed by direct sequencing of genomic DNA extracted from peripheral blood leukocytes of all family members. The sequence analysis of all TSHR gene exons and intron borders revealed two genomic variants. The first was a single nucleotide polymorphism (SNP) within exon seven (Asn187Asn), whereas the other was located in intron seven (IVS7+68T>G). All affected members, two asymptomatic brothers with sub-clinical hyperthyroidism, and their father were heterozygous for those two genomic variants. Anti-thyroid drug treatment for several months successfully relieved symptoms in one subject, whereas the remaining patients required total thyroidectomy to control their disease. This is the first Jordanian family with familial non-autoimmune hyperthyroidism, with mutations affecting the TSHR gene.

  14. High frequency of positive anti-thyroid peroxidase antibodies (ATPO) in adult subjects without known thyroid disease, Santiago de Chile

    International Nuclear Information System (INIS)

    Background: Anti-thyroid peroxidase antibodies have a pathogenic role in Hashimoto thyroiditis. Between 10 and 19% of individuals without thyroid disease, have positive titers of these antibodies. Aim: To study the frequency of positive titers of anti-thyroid peroxidase antibodies in healthy individuals. Material and Methods: A blood sample, to measure anti-thyroid peroxidase antibodies and thyroid stimulating hormone (TSH) by chemiluminescence assay, was obtained from 67 women and 62 men aged 45 ± 14 years, without a personal or familiar history of thyroid diseases and normal thyroid palpation. The cutoff point of the manufacturer to consider positive a titer of anti-thyroid peroxidase antibodies was set at 35 IU/ml. Results: Twenty-eight women and 28 men had positive antibody titers (43% of the sample). Subjects in the upper tercile of anti-thyroid peroxidase antibody titers had a higher TSH than those in the second tercile, although within normal limits (1.73 ± 0.74 and 1.37 ± 0.59 mlU/L, respectively p = 0.02) Conclusions: Forty three percent of the studied subjects without personal or familial history of thyroid diseases had positive titers of anti-thyroid peroxidase antibodies. Further prospective studies should evaluate whether this observation discloses an increase in thyroid autoimmune disease in a population with increased iodine intake

  15. Should neck pain in a patient with Hashimoto′s thyroiditis be underestimated? A case and review of the literature

    2012-01-01

    Full Text Available Hashimoto′s Thyroiditis (HT is an autoimmune disease and the most frequent cause of hypothyroidism. Subacute thyroiditis (SAT overlapping HT is a rare entity. A 69-year-old female patient with HT and multinodular goiter has been followed on levothyroxine replacement therapy for 7 years. She presented with neck pain radiating to the right ear persisting for 2 months. She was prescribed analgesics and antibiotics by other physicians during that period, which did not work. Her vital signs were stable with no tachycardia or fever. The right lobe of the thyroid gland was tender on palpation. Her TSH level was 3.94 mIU/ml, ESR 23 mm/h, CRP 3.2 mg/l, WBC 4900/μl at presentation. Thyroid ultrasonography revealed a hypoechoic area over the tender lobe. Power Doppler imaging revealed almost no blood flow in that area. She was started on methylprednisolone 32 mg/day. At day 10 of therapy, her symptoms had completely resolved. Ultrasonography repeated showed that the hypoechoic area had disappeared. Glucocorticoid dosage was tapered and stopped. Emergence of subacute thyroiditis in a case with preexisting Hashimoto′s thyroiditis is a quite rare condition, but should be kept in mind along with a painful attack of HT in the differential diagnosis.

    Danish women with Turner's syndrome followed up for 12,461 person-years between 1980 and 2004. Standardized incidence ratios (SIRs) of first hospitalization for autoimmune disease and 95% confidence intervals (95% CIs) were used as measures of relative risk. RESULTS: The overall risk of autoimmune...... disease among women with Turner's syndrome was twice that among Danish women in general (SIR 2.1 [95% CI 1.6-2.7]). For autoimmune diseases with a female predominance, the SIR among women with Turner's syndrome was 1.7 (95% CI 1.2-2.4), whereas the SIR for autoimmune diseases with a male predominance...... among these women was 3.9 (95% CI 2.5-5.8). Associations were strongest for Hashimoto thyroiditis (SIR 14.6 [95% CI 6.7-27.1]), a strongly female-predominant condition, and type 1 diabetes mellitus (SIR 4.1 [95% CI 2.5-6.3]).

    Lingual thyroid is a rare embryological anomaly and originates from failure of the thyroid gland to descend from the foramen caecum to its normal eutopic pre-laryngeal site. The ectopic gland located at the base of the tongue is often asymptomatic but may cause local symptoms such as dysphagia, dysphonia with stomatolalia, upper airway obstruction and haemorrhage, often with hypothyroidism. One case is presented, in a 5 year-old girl patient, who complained of sensation of a foreign body and ...

  4. Effects of iodine and thyroid hormones in inducing and treating Hashimoto's thyroiditis

    International Nuclear Information System (INIS)

    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 significant 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.)

    The active accumulation of I- in the thyroid gland is mediated by the Na(+)-I- symporter and driven by the Na+ gradient generated by the Na+/K(+)-ATPase. Thyrotropin (TSH) stimulates thyroidal I- accumulation. Rat thyroid-derived FRTL-5 cells require TSH to accumulate I-. TSH withdrawal for over 7 days results in complete loss of Na(+)-I-symport activity in these cells [Weiss, S. J., Philp, N. J. and Grollman, E. F. (1984) Endocrinology 114, 1090-1098].

    2013-01-01

    Full Text Available Thyroid hemiagenesis is a rare congenital anomaly resulting from failure of one thyroid lobe development. We report a 23-year-old female presented with Hashimoto’s thyroiditis in left lobe, associated with hemiagenesis of right lobe and isthmus which was previously diagnosed as Graves’ hyperthyroidism, but developed further into Hashimoto’s thyroiditis after being treated with antithyroid drugs. The symptoms of hyperthyroidism in the current case led to the diagnostic confirmation by scintiscanning of an absent lobe. The antithyroid pharmacotherapy by thiamazole was used. However, due to symptoms of hypothyroidism, it was discontinued two months later, so thyroid hormone substitution was reintroduced. Antithyroid antibody studies and ultrasonography documented the presence of Hashimoto’s thyroiditis.

  7. Scintigraphic findings of the thyroid in hypothyroid patients with blocking-type TSH-receptor antibodies

    International Nuclear Information System (INIS)

    The present study was designed to analyse the scintigraphic appearance of the thyroid in hypothyroid patients with blocking-type TSH receptor antibodies (TRAbs). Eleven hypothyroid patients with autoimmune thyroiditis positive for TSH binding inhibitor immunoglobulins (TBII) [80% ± 12 (SD)%; normal 99mTc than those in group 2 (P<0.05). Interestingly, three patients in group 1 were positive for thyroid-stimulating antibodies (TSAbs) (249% ± 17%; normal <145%), which were not detected in the remaining eight patients. Antibodies against thyroglobulin and microsomal antigens were detected in nine (81.8%) and 11 (100%) patients, respectively, but neither of these titres correlated with the scan image. Three patients in group 1 underwent scintigraphy again after treatment with thyroxine, at which time the functioning lesion was not noted. Fourteen hypothyroid patients with negative TBII displayed no such scintigraphic findings. Chronic stimulation of the thyroid by TSAbs and/or TSH might be responsible for the presence of the functioning lesion, but clarification of the mechanism requires further studies. In summary (1) TSAbs were detected in three (27.3%) of 11 hypothyroid patients with blocking TRAbs; (2) thyroid scintigraphy revealed the presence of localized functioning area(s) in approximately half of these cases.

    Full Text Available Hyperthyroidism is a condition characterized by excessive production of thyroid hormones. Propylthiouracil (PTU is commonly used as first line drug in the management of hyperthyroidism. This is a case report of 24-year-old female, a known case of hyperthyroidism since 4 years, who came with a history of fever and myalgia since 3 days and dyspnea with coughing out of blood since 1 day. Patient was taking PTU (100 mg per day since 4 years for hyperthyroidism. Patient was immediately intubated for type-II respiratory failure. Diagnosed to be having PTU-induced autoimmune disease. PTU was stopped and treated with methylprednisolone and cyclophosphamide. Clinical features improved over a period of 8 days and discharged home successfully. Having a high suspicion for the onset of autoimmune disease in hyperthyroidism patients who are on PTU therapy and timely treatment with immunosuppressants and supportive care along with the withdrawal of the drug can make a difference in morbidity and mortality.

  9. Thyroid diseases

    International Nuclear Information System (INIS)

    This chapter reviews the correlation between thyroid disease, other than cancer, and radiation in the literature. Radiation-induced thyroid disturbance is discussed in the context of external and internal irradiation. External irradiation of 10 to 40 Gy may lower thyroid function several months or years later. Oral administration of I-131 is widely given to patients with Basedow's disease; it may also lower thyroid function with increasing radiation doses. When giving 70 Gy or more of I-131, hypothyroidism has been reported to occur in 20-30% and at least 10%. Thyroiditis induced with internal I-131 irradiation has also been reported, but no data is available concerning external irradiation-induced thyroiditis. The incidence of nodular goiter was found to be several ten times higher with external irradiation than internal irradiation. Thyroid disturbance is correlated with A-bomb survivors. A-bomb radiation can be divided into early radiation within one minute after A-bombing and the subsequent residual radiation. Nodular goiter was significantly more frequent in the exposed group than the non-exposed group; it increased with increasing radiation doses and younger age (20 years or less) at the time of exposure. The incidence of decrease in thyroid function was higher with increasing radiation doses. However, in the case of Nagasaki, the incidence of hypothyroidism was significantly higher in the low-dose exposed group, especially A-bomb survivors aged 10-39 at the time of exposure and women.

US, although highly accurate in identifying thyroid nodules and diffuse thyroid diseases, is still not sufficiently accurate to evaluate them. US-elastography has been introduced in order to further increase US accuracy in many fields and eventually for thyroid disease. The aim of the present paper it to provide an update of the literature on different available techniques and the results reported both for thyroid nodules differentiation and for diffuse thyroid disease evaluation. Advantages and limitations of elastography are also discussed.

    The clinical and pathological presentation of thyroid nodules among younger and adult patients was compared in an iodine-deficient (ID) region. Data of 3,010 consecutive patients younger than 20 years and 3,010 patients older than 20 years were compared. The proportion of nodular goiters (22.8% versus 39.3%), the ratio of surgically treated nodules (33.2% versus 15.2%), and the proportion of malignant nodules (4.3% versus 2.1%) among diseased patients differed significantly between the two groups (younger versus adult). Nine papillary and 1 medullary carcinoma were found among children, while 15 papillary, 2 follicular, 1 insular, 1 anaplastic, and 1 medullary carcinomas occurred among adults. The ratio of follicular adenoma to hyperplastic nodules (3 : 1 to 1 : 1.67), the proportion of follicular variant (77.8% versus 26.7%), T4 tumors (77.8% versus 33.3%), and tumors with lymph node metastasis (88.9% versus 66.7%) were significantly higher among younger papillary carcinoma patients. No malignancies occurred among spongiform and central type cysts. Similarly to iodine-sufficient regions, more nodules are malignant and carcinomas have a clinically more aggressive presentation in children in comparison with adult patients in ID. Taking the significantly greater proportion of adenomas and the lack of follicular carcinoma into account, a conservative approach has to be considered in follicular tumors among children.

Data of 3,010 consecutive patients younger than 20 years and 3,010 patients older than 20 years were compared. The proportion of nodular goiters (22.8% versus 39.3%, the ratio of surgically treated nodules (33.2% versus 15.2%, and the proportion of malignant nodules (4.3% versus 2.1% among diseased patients differed significantly between the two groups (younger versus adult. Nine papillary and 1 medullary carcinoma were found among children, while 15 papillary, 2 follicular, 1 insular, 1 anaplastic, and 1 medullary carcinomas occurred among adults. The ratio of follicular adenoma to hyperplastic nodules (3 : 1 to 1 : 1.67, the proportion of follicular variant (77.8% versus 26.7%, T4 tumors (77.8% versus 33.3%, and tumors with lymph node metastasis (88.9% versus 66.7% were significantly higher among younger papillary carcinoma patients. No malignancies occurred among spongiform and central type cysts. Similarly to iodine-sufficient regions, more nodules are malignant and carcinomas have a clinically more aggressive presentation in children in comparison with adult patients in ID. Taking the significantly greater proportion of adenomas and the lack of follicular carcinoma into account, a conservative approach has to be considered in follicular tumors among children.

    Full Text Available The autoimmune thyroid disease is the most prevalent autoimmune affection and affects until 5% of the general population; its development is given by the interaction between genetic susceptibility and other factors. One particularity is the early production of thyroid autoantibodies against thyroid peroxidase (aTPO which often predicts the clinical development of the disease. The genetic susceptibility for the thyroid autoimmunity (AIT is generated by genes of the HLA and by other genes candidates of the chromosome 2q33. This region contains the genes: CTLA-4 and CD 28. Several polymorphisms of both would be associated according to previous studies. Objective: To analyze and to compare the simple nucleotide polymorphism distribution (SNP of CD28 (IVS3+17 T/C and CTLA-4 (+ 49 A/G in patients with aTPO> 10 IU/ml (AIT compared to a control group aTPO ≤ 10 IU/ml with no AIT. Subjects and Methods: We have studied 69 patients with AIT and 36 control subjects. Serum aTPO were measured by using chemiluminescence immunoassay (IMMULITE1000, Siemens. Genomic DNA was prepared from peripheral white blood cells. The amplification of the genes was carry out by polymerase chain reaction (PCR. Statistical analyses : the differences between groups were made using the chisquare test. P less than 0.05 was considered statistically significant. Results: There was a significant difference of genotype CD 28 C/T in patients with AIT compared with controls (p=0.026. The genotypes of CTLA-4 was analyzed and there was no significant difference between AIT and controls. Analysis of genotypes association CD 28 C/T and CTLA-4 A/A or A/G, revealed significant difference comparing AIT versus controls (p= 0.013. Conclusions: We found a possible association of genotype CD 28 C/T in individuals with AIT, since carriers of genotype C/T would have a risk three times higher to acquire AIT. The combination of genotypes CD 28 C/T and CTLA-4 A/A or A/G would increase the risk of

  17. Radiation damage to thyroid gland may be the reason of increase in frequency of non-Hodgkin's lymphoma and other hematological diseases

    International Nuclear Information System (INIS)

    Distribution of autoimmune thyroidities in the patients with diseases of blood system was investigated. Attribute of autoimmune thyroidities was revealed by the detection of antimicrosomal antibodies. It was established that the autoimmune thyroidities are more often in patients with various hematological diseases than in control group. It is supposed that the increase in frequency of some hematological diseases in residents suffered from the Chernobyl accident can be defined not only by the influence of the radiation on blood system, but also can be connected with damage to thyroid glands

    This study was done retrospectively to analyze the ultrasonographic (US) findings in thyroid scintigraphic hot areas (HA). Three-thousand, eight-hundred and thirty-nine consecutive patients who underwent {sup 99m}Tc-pertechnetate (n=3435) or {sup 123}I (n=457) scintigraphy were analyzed. HA were regarded as present when the tracer concentration was greater than the remaining thyroid tissue, or when hemilobar uptake was observed. High-resolution US examinations were performed with a real-time electronic linear scanner with a 7.5 or 10 MHz transducer. One hundred and four (2.7%) were found to be scintigraphic HA (n=120). US revealed a nodular lesion or well-demarcated thyroid tissue corresponding to the HA in 94 areas (78.4%, Category 1), an ill-defined region with different echogenicity in 13 areas (10.8%, Category 2), and no correlating lesion in 13 areas (10.8%, Category 3). These 104 patients included 43 with adenomatous goiter (59 areas), 33 with adenoma, 11 with Hashimoto's thyroiditis, 5 with primary thyroid cancer, 4 with euthyroid ophthalmic Graves' disease (EOG), 3 with hemilobar atrophy or hypogenesis, 2 with hemilobar agenesis, 2 with hypothyroidism with blocking-type TSH-receptor antibodies (TSHRAb), 1 with acute suppurative thyroiditis. Among the 59 adenomatous nodules and 33 adenomas, 51 (86.4%) and 32 (97.0%), respectively, belonged to Category 1. A solitary toxic nodule was significantly larger and occurs more often in older patients than in younger patients. On the other hand, all 17 patients with known autoimmune thyroid diseases including Hashimoto's thyroiditis, EOG and hypothyroidism with blocking TSHRAb belonged to Category 2 or 3. Possible underlying mechanisms are hyperfunctioning tumors or nodules, localized functioning thyroid tissue freed from autoimmune destruction, inflammation or tumor invasion, congenital abnormality, clusters of hyperactive follicular cells caused by long-term TSH and/or TSHRAb stimulation, asymmetry

    In this paper the molecular aspects of the relationships between infectious agents and autoimmune diseases, the mechanisms of immune response to infectious agents, and the more recent hypotheses regarding the cause of autoimmune diseases are discussed. The antigens are processed and selected by their immunogenicity, and presented by HLA molecules to the T cell receptor. These events initiate the immune response with the activation and proliferation of T-lymphocytes. Although there are several hypotheses regarding the cause of autoimmune diseases and too many findings against and in favor of them, there is still no conclusive data. All these hypothesis and findings are discussed in the context of the more recent advances. PMID:1615352

    Full Text Available Context: Alopecia areata (AA is a common form of localized, non-scarring hair loss. The etiopathogenesis of the disease is still unclear, but the role of autoimmunity is strongly suggested. AA is commonly associated with various autoimmune disorders; the most frequent among them is autoimmune thyroid disorders. Aim: To determine whether AA is associated with thyroid autoimmunity or thyroid function abnormalities in Egyptian patients. Materials and Methods: Fifty subjects with AA (37 males and 13 females without clinical evidence of thyroid disorders were selected from Dermatology Outpatient Clinic, Menoufiya University Hospital, Menoufiya Governorate, Egypt, during the period from June 2009 to February 2010. They were divided into 3 groups according to severity of AA. Fifty age and sex-matched healthy volunteers (35 males and 15 females were selected as a control group. Every case and control were subjected to history taking, complete general and dermatological examination. Venous blood samples were taken from cases and controls after taking their consents for measurement of thyroid stimulating hormone (TSH, free T3, freeT4 and detection of Anti-thyroglobulin Antibody (Tg-Ab and Anti-thyroid Peroxidase Antibody (TPO-Ab. Results: Subclinical hypothyroidism was detected in 16% of cases. There were statistically significant differences between cases and controls regarding levels of TSH, free T3 and free T4. There were significant differences between cases and controls regarding the presence of Tg-Ab and TPO-Ab. Conclusions: Every patient with AA should be screened for thyroid functions and presence of thyroid autoantibodies even in absence of clinical manifestations suggestive of thyroid affection.

    Full Text Available The purpose of our study was to investigate the main parameters of thyroid status in patients with rheumatoid arthritis (RA, as well as particularities of course of this disease depending on of thyroid gland function disorder. Materials and methods. 52 women with RA were examined. The first group consisted of 11 women with subclinical and manifestive hypothyroidism the second one 41 women without thyroid gland function disorder. The group comparison was conducted on main indexes of thyroid gland condition the hormon level, AT-TPO, ultrasonic data, as well as clinical and laboratory RA data. Results. In women with hypothyroidism the systemic manifestations of RA were more often truely diagnosed; DAS28 indexes, ESR, the number ot swollen joints were higher. The high level ot AT-TPO was diagnosed in 54,55% – I group and in 31,7% – II group TTG level was really less in patients receiving synthetic glycocorticoids. Small thyroid gland volume was diagnosed in 23,07% of examined patients. The thyroid gland status indexes in them did not differ from patients with normal thyroid gland volume. Reliable increasing of the peripheral resistance index was revealed in lower thyroid artery according to the ultrasonic study data under the reduced thyroid gland size. Conclusions. High incidence of hypothyroidism and AT-TPO carriage in RA was revealed. Hypothyroidism development is accompanied by high clinic-laboratory RA activity. The reduction of the thyroid gland volumes in RA is possibly stipulated not only by autoimmunal pathology, but also chronic ischemia of the organ in the conditions of immune-complex vasculitis and early atherosclerosis. The TTG level in patients with RA is defined not only by pathology of the thyroid gland, but glycocorticoid therapy as well.

    Full Text Available Over an 8-year period, a male patient presented three times to an endocrinologist with strikingly similar presentations, including palpitations, anxiety, and tremors. Each of his presentations occurred following either the birth of one of his two children or his wife’s late termination of pregnancy. This patient’s illness followed the typical time course of silent thyroiditis: hyperthyroidism, followed by euthyroidism, a late hypothyroid phase, and then a complete resolution of symptoms and normalization of thyroid function tests over a period of several months. We discuss the curious clinical presentation, diagnostic evaluation, and a literature review of alternate explanations for this patient’s condition, including a discussion of the impact of seasonal shift, spousal’s autoimmune disease, stress, and evolutionary changes in males postpartum. Although the differential diagnosis is broad in this case and the thyrotoxicosis could have coincidentally followed pregnancies of the patient’s wife, documented hormonal changes in men during postpartum period in conjunction with the timeline of the patient’s condition are suggestive of recurrent “sympathetic” postpartum thyroiditis. To our knowledge, this is the first case report of recurrent painless thyroiditis in a man following pregnancies of his wife with Hashimoto’s thyroiditis.

    Pediatric thyroid diseases cover a large spectrum of congenital and acquired forms, ranging from congenital primary or central hypothyroidism, autoimmune thyroid disease, iodine deficiency, rare genetic defects of thyroid hormone action, metabolism and cell membrane transport to benign nodules and malignant tumors. The previous 15 papers of the textbook Paediatric Thyroidology gave a systematic overview of the current knowledge and guidelines on all these diseases. In this final paper, the authors collected a series of patient histories from their clinics illustrating frequently encountered clinical problems and providing key learning points and references to each case. Although not fully comprehensive, it aims at providing relevant clinical knowledge on thyroid diseases of the neonate, the child, and the adolescent. PMID:25231455

  5. Thyroid effects

    International Nuclear Information System (INIS)

    Risk coefficients for thyroid disorders have been developed for both 131I and external x or gamma low-LET radiation. A linear, no-threshold model has been used for thyroid neoplasms. A linear, threshold model has been used for other thyroid disorders. Improvements since the Reactor Safety Study were made possible by relevant new animal and human data. Major changes are as follows. Animal data are used to supplement the human experience where necessary. A specific risk estimate model is used for thyroid neoplasms, which accounts for observed effects of gender and age at exposure on risk. For thyroid cancer, the basis of the risk coefficients is the experience of North Americans following x-irradiation for benign disease in childhood. This recognizes possible differences in susceptibility in people of different heritage. A minimum induction period for thyroid neoplasms following irradiation is used to define periods at risk. An upper bound risk coefficient for cancer induction following exposure to 131I is based on human experience at relatively low dose exposures. While the overall lifetime risks of death due to thyroid cancer are consistent with projections by the ICRP, BEIR III, and UNSCEAR Reports, the current model permits greater flexibility in determining risk for population subgroups. 88 references, 8 tables

  14. Triple ectopic thyroid: A rare entity

    International Nuclear Information System (INIS)

    Ectopic thyroid tissue is an uncommon congenital aberration. It is extremely rare to have three ectopic foci at three different sites. The thyroid scan has been used successfully to diagnose ectopic thyroid tissue. We report a case of ectopic thyroid tissue at base of tongue, another at the level of hyoid and third one as aberrant tissue at suprahyoid location in a 16 year old female who presented with swelling in front of neck. This patient was clinically diagnosed as thyroglossal cyst and was being planned for surgery. Preoperative thyroid scan helped in establishing diagnosis of ectopic thyroid which was the only functioning thyroid tissue. Thus, it prevented unnecessary surgery. Therefore it is suggested that thyroid scan and USG/CT scan must be done as routine work up in neck swellings pre operatively to avoid unnecessary surgeries

    The three common themes that underlie the induction and perpetuation of autoimmunity are genetic predisposition, environmental factors, and immune regulation. Environmental factors have gained much attention for their role in triggering autoimmunity, with increasing evidence of their influence as demonstrated by epidemiological studies, laboratory research, and animal studies. Environmental factors known to trigger and perpetuate autoimmunity include infections, gut microbiota, as well as physical and environmental agents. To address these issues, we will review major potential mechanisms that underlie autoimmunity including molecular mimicry, epitope spreading, bystander activation, polyclonal activation of B and T cells, infections, and autoinflammatory activation of innate immunity. The association of the gut microbiota on autoimmunity will be particularly highlighted by their interaction with pharmaceutical agents that may lead to organ-specific autoimmunity. Nonetheless, and we will emphasize this point, the precise mechanism of environmental influence on disease pathogenesis remains elusive. PMID:25998909

    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.

  20. Autoimmunity: from black water fever to regulatory function.

    Science.gov (United States)

    Chang, Christopher

    2014-01-01

    Autoimmunity is a field that has only been around for a little over a century. Initially, it was thought that autoimmunity could not happen, that the body would never turn on itself (i.e. "horror autotoxicus"). It was only around the First World War that autoimmunity was recognized as the pathogenesis of various diseases, including rheumatoid arthritis. The discovery of Compound E led to successful treatment of patients with autoimmune diseases, but it was not till later that the adverse effects of this class of drugs were elucidated. The "modern" age of autoimmunity began around 1945 with the description of blackwater fever, and most of the subsequent research on hemolytic anemia and the role of an autoantibody in its pathogenesis led to a description of the anti-globulin reaction. The lupus erythematous (LE) cell was recognized in the mid-1940s by Hargreaves. His research carried on into the 1960s. Rheumatoid factor was also first described in the 1940s as yet another serum factor with activity against globulin-coated sheep red blood cells. The concept of autoimmunity really gained a foothold in the 1950s, when autoimmune thyroid disease and idiopathic thrombocytopenia were first described. Much has happened since then, and our understanding of autoimmunity has evolved now to include mechanisms of apoptosis, signaling pathway derangements, and the discovery of subsets of T cells with regulatory activity. The modern day study of autoimmunity is a fascinating area of research, and full understanding of the pathogenesis of autoimmune diseases is far from being completely elucidated. PMID:24491820
