    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...

    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.

    Full Text Available Introduction, Autoimmune diseases are chronic conditions initiated by the loss of immunological tolerance to self-antigens. They constitute heterogeneous group of disorders, in which multiple alterations in the immune system result in a spectrum of syndromes that either target specific organs or affect the body systematically. Recent epidemiological studies have shown a possible shift of one autoimmune disease to another or the fact that more than one autoimmune disease may coexist in a single patient or in the same family. Numerous autoimmune diseases have been shown to coexist frequently with thyroid autoimmune diseases. Autoimmune thyroid disease and other organ specific non-endocrine autoimmune diseases. This part of the study reviews the prevalence of autoimmune thyroid disease coexisting with: pernicious anaemia, vitiligo, celiac disease, autoimmune liver disease, miastenia gravis, alopecia areata and sclerosis multiplex, and several recommendations for screening have been given. Autoimmune thyroid disease and other organ non-specific non-endocrine autoimmune diseases. Special attention is given to the correlation between autoimmune thyroid disease and rheumatoid arthritis, systemic lupus erythematosus, syndrome Sjögren, systemic sclerosis and mixed connective tissue disease. Conclusions. Screening for autoimmune thyroid diseases should be recommended in everyday clinical practice, in patients with primary organ-specific or organ non-specific autoimmune disease. Other­wise, in patients with primary thyroid autoimmune disease, there is no good reason of seeking for all other autoimmune diseases, although these patients have a greater risk of developing other autoimmune disease. Economic aspects of medicine require further analyzing of these data, from cost/benefit point of view to justified either mandatory screening or medical practitioner judgment.

    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

    Neuromyelitis optica (NMO or Devic's syndrome) is a rare relapsing demyelinating disease of the central nervous system (CNS) that mainly affects the spinal cord and optic nerves and shares many clinical and radiological features with multiple sclerosis. The association of NMO with other autoimmune diseases was reported, but very few reports described association with autoimmune thyroid disease. Early differentiation between NMO and multiple sclerosis is very important as the natural course and treatment regimens differ significantly. We report a case of a 50-year-old woman who was admitted initially with vomiting, hiccups and paraesthesias but was not diagnosed with NMO and presented with a severe progression of the disease. The patient was also diagnosed to have autoimmune thyroiditis with lymphocytic infiltration of the thyroid which progressed from hyperthyroidism to hypothyroidism. NMO diagnosis was established with seropositivity for NMO-IgG and MRI showing longitudinally extensive spinal cord lesions (3 or more spinal segments). In spite of treatment, the response was poor due to lack of early diagnosis and aggressive immunosuppressant therapy.

    We report six cases of autoimmune thyroid disease associated with chronic urticaria and briefly review the literature, including the histopathological nature of such lesions, and their aetiology and pathogenesis. In view of the prevalence of thyroid disease in patients with chronic urticaria, screening measurements of thyrotropin and anti-thyroperoxidase antibodies are recommended, although negative antibodies do not exclude a relationship between urticaria and thyroid autoimmunity. After failure of conventional therapy for urticaria, patients who are apparently clinically euthyroid may be considered for a trial with levothyroxine. Improvement of urticaria was seen with levothyroxine treatment in three of four patients with only marginal abnormalities in thyroid function.

    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

    Full Text Available AbstractBackground and Purpose: chronic urticaria is a tormenter and does not have a known etiology. Association between chronic urticaria and thyroid auto-immunity has shown different results. The aim of this study is to evaluate the effect of Levo-thyroxine on the chronic urticaria and association between chronic urticaria with thyroid auto-immunity.Materials and Methods: In a prospective case-control study, we compared the frequency of thyroid auto antibodies in 60 patients (all females, with exception of six males, ages 15 to 60 years with chronic urticaria and compared with 60 mached age healthy volunteers. All cases with chronic urticaria and control group were normal CBC, antinuclear antibodies, rheumatoid factors, complement, stool exam, liver function test (LFT, kidney function and skin prick test, prior to being referred to us. We performed thyroid auto antibodies, thyroid hormones and IgE antibodies before treating all subjects. Half of them with positive anti-thyroid antibody (n=11, received Levo-thyroxine (100 μg daily for 1 month and the remaining half (n=11 were control group.Results: The frequency of thyroid auto antibodies was significantly higher in patients with chronic urticaria than in healthy control (36.6% vs. 9%; p<0.01.( All patients were euthyroid, however, one was found to have increased anti-thyroid antibody levels with sub clinical hypothyroidism (TSH increased, low T4. Total serum IgE increased in ten cases of patients group (16.6% compared with six control groups (10%. Nine patients (40% had complete response, five patients (30% had partial response and five patients (30% did not show any response to treatment compared with control group, in which complete and partial resolution was 30% and others with no resolution.Conclusion: chronic urticaria may be associated with thyroid disorders (positive anti- thyroid antibodies despite normal thyroid function test.

    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.

  1. Encephalopathy Associated with Autoimmune Thyroid Disease: A Potentially Reversible Condition

    2016-01-01

    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.

T1D and AITD were found to have a 20% and 30% frequency of overlap respectively at diagnosis. In conclusion, TGA positivity was high in the Chinese population having existing T1D and/or AITD, and even higher when both diseases 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.

    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.

    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.

    Evidence suggests that in most industrialized countries autoimmune disorders, including chronic lymphocytic thyroiditis, are increasing. This increase parallels the one regarding differentiated thyroid cancer, the increment of which is mainly due to the papillary histotype. A number of studies have pointed to an association between chronic lymphocytic thyroiditis and differentiated thyroid cancer. The upward trend of these two thyroid diseases is sustained by certain environmental factors, such as polluting substances acting as endocrine disrupting chemicals. Herein we will review the experimental and clinical literature that highlights the effects of environmental and occupational exposure to polluting chemicals in the development of autoimmune thyroid disease or differentiated thyroid cancer. Stakeholders, starting from policymarkers, should become more sensitive to the consequences for the thyroid resulting from exposure to EDC. Indeed, the economic burden resulting from such consequences has not been quantified thus far.

    Introduction, Autoimmune diseases are chronic conditions initiated by the loss of immunological tolerance to self-antigens. They constitute heterogeneous group of disorders, in which multiple alterations in the immune system result in a spectrum of syndromes that either target specific organs or affect the body systematically. Recent epidemiological studies have shown a possible shift of one autoimmune disease to another or the fact that more than one autoimmune disease may coexist in a...

  12. 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)

  13. 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.

    The association between a familial history of autoimmune disease and childhood acute leukemia was investigated in a French case-control study that, overall, was designed to assess the role of perinatal, infectious, environmental, and genetic factors in the etiology of childhood acute leukemia. Familial histories of autoimmune disease in first- and second-degree relatives were compared in 279 incident cases, 240 cases of acute lymphocytic leukemia (ALL) and 39 cases of acute non-lymphoblastic leukemia (ANLL), and 285 controls. Recruitment was frequency matched by age, gender, hospital, and ethnic origin. Odds ratios (OR) were estimated using an unconditional regression model taking into account the stratification variables, socioeconomic status, and familial structure. A statistically significant association between a history of autoimmune disease in first- or second-degree relatives and ALL (OR, 1.7; 95% confidence interval (CI), 1.0-2.8) was found. A relationship between thyroid diseases overall and ALL (OR, 2.0; 95% CI, 1.0-3.9) was observed. This association was more pronounced for potentially autoimmune thyroid diseases (Grave's disease and/or hyperthyroidism and Hashimoto's disease and/or hypothyroidism) (OR, 3.5; 95% CI, 1.1-10.7 and OR, 5.6; 95% CI, 1.0-31.1, respectively for ALL and ANLL), whereas it was not statistically significant for the other thyroid diseases (thyroid goiter, thyroid nodule, and unspecified thyroid disorders) (OR, 1.6; 95% CI, 0.7-3.5 and OR, 1.3; 95% CI, 0.2-7.0, respectively, for ALL and ANLL). The results suggest that a familial history of autoimmune thyroid disease may be associated with childhood acute leukemia.

  17. The role of stress in the clinical expression of thyroid autoimmunity.

    During stress, activation of the hypothalamic-pituitary-adrenal axis and the sympathoadrenal system leads to increased secretion of glucocorticoids and catecholamines, respectively, in order to maintain homeostasis. Recent evidence suggests that stress hormones, acting on antigen-presenting immune cells, may influence the differentiation of bipotential T helper (Th) cells away from Th1 and toward a Th2 phenotype. This results in suppression of cellular immunity and potentiation of humoral immunity. Thyroid autoimmunity is clinically expressed as Hashimoto's thyroiditis (HT) and its variants (sporadic or postpartum thyroiditis) or as Grave's disease (GD). The different phenotypic expression of thyroid autoimmunity is largely dependent on the balance of Th1 versus Th2 immune response. A predominantly Th1-mediated immune activity may promote apoptotic pathways on thyroid follicular cells leading to thyroid cell destruction and HT. Conversely, predominance of Th2-mediated immune response may induce antigen-specific B lymphocytes to produce anti-TSH receptor (TSHr) antibodies causing GD. The weight of evidence from epidemiological and case-control studies supports an association between stress and GD. On the other hand, there is little information available on the effect of stress on HT, but there is evidence for an increase in postpartum thyroiditis, following the cellular immune suppressive effect of pregnancy. Whether stress has a causative effect on GD remains elusive. Circumstantial evidence supports the hypothesis that stress may influence the clinical expression of thyroid autoimmunity in susceptible individuals favoring the development of GD by shifting the Th1-Th2 balance away for Th1 and toward Th2. Conversely, recovery from stress or the immune suppressive effect of pregnancy may induce a Th2 to Th1 "return shift" leading to autoimmune (sporadic) or postpartum thyroiditis, respectively.

    Encephalopathy associated with autoimmune thyroid disease is a rare condition presenting in the setting of autoimmune thyroid disease and characterized by unspecific neurological and\\/or psychiatric symptoms. 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

    Abstract 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.

    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

    Full Text Available 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 < 10 times the upper limit of normal underwent upper gastrointestinal endoscopy and 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.

    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

    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.

    Full Text Available The aims of this study were to evaluate the utility of shear wave elastography (SWE using acoustic radiation force impulse (ARFI for diagnosing chronic autoimmune thyroiditis (CAT and to verify the effect of fibrotic thyroid tissue on shear wave velocity (SWV. The subjects were 229 patients with 253 normal thyroid lobes (controls and 150 CAT lobes. The SWV for CAT (2.47 ± 0.57 m/s was significantly higher than that for controls (1.59 ± 0.41 m/s (P<0.001. The area under the receiver operating characteristics (ROC curve for CAT was 0.899, and the SWV cut-off value was 1.96 m/s. The sensitivity, specificity, and diagnostic accuracy were 87.4%, 78.7%, and 85.1%, respectively. Levels of anti-thyroperoxidase antibodies and thyroid isthmus thickness were correlated with tissue stiffness in CAT. However, there was no correlation between levels of anti-thyroglobulin antibodies and tissue stiffness. Quantitative SWE is useful for diagnosing CAT, and it is possible that SWE can be used to evaluate the degree of fibrosis in patients with CAT.

    Full Text Available Autoimmune polyendocrine syndrome Type II (APS II, also known as polyglandular autoimmune syndrome Type II or Schmidt syndrome, is constellations of multiple endocrine gland insufficiencies. It is a rare, but most common of the immunoendocrinopathy syndrome. It is characterized by the obligatory occurrence of autoimmune Addison′s disease in combination with thyroid autoimmune diseases and/or Type I diabetes, hypogonadism, hypophysitis, myasthenia gravis, vitiligo, alopecia, pernicious anemia, and celiac disease. Here, we report a case of 38-year-old female patient presented with shock, further diagnosed to have APS II.

    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.

  20. 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)

    Forty-one single-chain variable region fragments (scFvs) directed against thyroid peroxidase (TPO) were obtained by phage display libraries constructed from thyroid-infiltrating B cells of Graves' disease patients. Among these scFvs, 24.4% used a Vkappa light chain whereas 75.6% shows a light chain of Vlamda origin. Study of light chain gene usage in the TPO antibody repertoire demonstrated a dominance of the Vkappa 1-39 and Vlambda 1-51 genes. Thyroid peroxidase probing of overlapping peptides covering the amino acid sequences of anti-TPO T2/kappa and T13/lambda variable regions demonstrated a more restricted antigen recognition on T13/lambda than on T2/kappa. These two recombinant antibodies, expressed as whole IgG1 in the baculovirus/insect cell system, inhibited the binding to TPO of serum TPO autoantibodies whatever the light chain. Our study indicates that lambda as well as kappa light chain usage are found in the TPO antibody repertoire of thyroid-infiltrating B cells and are pertinent in the pathogenesis of autoimmune thyroid disease.

    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

  3. 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.

    Full Text Available 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.

    Summary: To explore immune intervention effects of the combined use of cycloporin A (CsA) and1, 25-dihydroxyvitamin D3[1,25 (OH)2D3] at low doses on experimental autoimmune thyroiditis(EAT), porcine thyroglobulin (pTG) was injected into a CBA mouse at the dose of 100 μg on day0 and day 14 to establish the model of EAT. The immune prevention group from day 0 to day 28,and treatment group from day 10 to day 38 were daily administered CsA (10 mg/kg) intragastri-cally and/or 1,25(OH)2D3(0. 2 μg/kg) ip. After immunized by pTG, the mice were sacrificed onday 28 and day 38 to examine their thyroid gland pathologically, and to check the levels of serumporcine thyroglobulin antibodies (pTGAb), porcine thyromicrosomal antibodies (pTMAb). Theincidences of EAT in the immune prevention group and treatment group, with administration oflow dose of CsA and 1,25(OH)2Ds, were decreased respectively by 44.44 % and 37. 50 %. Thoseof severe disease in the two groups were decreased respectively by 71.43 % and 60. 32 %. Thelevels of serum pTGAb and pTMAb in the immune prevention group were lower than those of thepositive control group. It was concluded that combined use of CsA and 1,25 (OH)2D3 at low dosescould effectively prevent EAT with a synergic effect.

    AIM To verify the prevalence of thyroid autoimmunity (TA) and the possible association between atopy and TA in children affected by skin disease. METHODS Three hundred and twenty-four children consecutively referred due to skin disease symptoms to our Pediatric Department were enrolled. One hundred and eighty-seven were diagnosed with atopic dermatitis (AD), 95 with acute urticaria, 40 with chronic urticaria (CU), and 2 with alopecia areata (AA). According to the work-up for atopy, the children were divided into two groups: Atopics and non-atopics. TA was diagnosed by serum thyroid peroxidase autoantibodies and/or thyroglobulin autoantibodies levels more than twice normal values over a period of two months by immunoassay. RESULTS In all children with skin disease, a significant prevalence of TA in atopics compared with non-atopics (13.67% vs 2.67%, P = 0.0016) and a significant association between TA and atopy (OR = 5.76, 95%CI: 1.71-19.35) were observed. These findings were confirmed as significant in children with AD: TA in atopics was 11.5%, while TA in non-atopics was 2.7% (P = 0.03, OR = 4.68, 95%CI: 1.02-21.38). In addition, atopics with CU showed a significantly higher prevalence of TA (26.9%), but none of the non-atopics showed CU (P = 0.0326). On the other hand, atopics with AA showed a 100% (2 out of 2) prevalence of TA, compared with none of the non-atopics. CONCLUSION In children with skin disease, atopy seems to be associated with an increased risk of TA. PMID:27610344

    A case of a type 1 diabetic woman with auto-immune thyroiditis is reported, in whom repeated exposure to insulin containing Genapol(R) (polyethylen-polypropylenglycol) over 3 years reproducibly parallels with an increase of serum TSH (thyroid-stimulating hormone) above the normal limit. Previously, adverse effects of Genapol(R) insulin have been related to its intraperitoneal application, and thought to be restricted to anti-insulin-immunity; activating effects on thyroid auto-immunity have been repeatedly disputed. We suggest that Genapol(R) insulin should be replaced by other insulin preparations with a better safety record.

    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.

    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

    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.

APS type 2 occurs most often in middle aged females and is rare in children. Here an 11 year old boy is reported with Addison's disease who developed symptom's of diabetes mellitus, goiter, malabsorption, macrocytic anemia and keratitis. APS type 2 occurs most often in middle aged females and is quite rare in children but one should think to autoimmune poly glandular syndrome type II in patient at any age especially in patients with Addison's disease.

  15. 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)

In total 1733 adolescent subjects were enrolled into the study (993 from an iodine-sufficient area--the Eastern Black Sea Region (group 1) and 740 from an iodine-deficient area--Middle Anatolia (group 2)). We measured free thyroxine (FT(4)), thyrotropin (TSH), antithyroid peroxidase antibodies (Anti-TPO), antithyroglobulin antibodies (Anti-Tg), and urinary iodine (UI), and examined the thyroid gland by ultrasound. Median urinary iodine excretion was found to be significantly different in group 1 and group 2 (139 micro/l vs 61micro/l, p 0.05). The percentage of anti-Tg positive subjects was found to be 17.6% in group 1 and 6.4% in group 2; that of anti-TPO positive subjects was 4.3% in group 1 and 1.5% in group 2. The prevalence of antithyroid antibody (anti-Tg and/or anti-TPO) positivity was significantly higher in group 1 than in group 2 (18.52% vs 6.62%; p iodine supplementation in Turkey has resulted in the elimination of iodine deficiency in the Eastern Black Sea Region, and this has been accompanied by an increase in the prevalence of autoimmune thyroiditis and thyroid dysfunction.

    The case is reported of a 27 year old woman who had mixed connective tissue disease (MCTD) associated with chronic active hepatitis and thyroiditis. Although hepatomegaly is sometimes observed in MCTD, only four cases of MCTD and chronic active hepatitis have been described. It is thought that this is the first report of an association between MCTD, chronic active hepatitis and thyroiditis.

    Background Thyroid-associated orbitopathy is commonly associated with Graves' disease with lid retraction, exophthalmos, and periorbital swelling, but rarely with autoimmune thyroiditis or euthyroid state. We reviewed 3 cases from our hospital whose antibodies to anti-receptor of TSH were normal. Methods Case 1: 60 year-old non-diabetic woman with bilateral glaucoma in treatment, recurrent media otitis and euthyroidism, acute onset of painless diplopia, and lid ptosis in the left eye. MRI of orbit showed increased size of the III right cranial pair and high levels of thyroid autoantibodies (Tab) anti-tiroglobulin (ATG) 115.1, anti-thyroid peroxidase (ATPO) 1751 U/mL. She started oral deflazacort 30 mg each 3 days. Sixty days later, complete remission of eye symptoms correlated with lower auto-antibodies level (ATG 19 ATPO 117). Case 2: 10 year-old girl. At age 8, she had diplopia, lid ptosis and limitations of upper gaze in the left eye. The neurological study discarded ocular myasthenia; with thyroid goitier, and hypothyrodism, she started oral levothyroxin. At age 10 with normal IRM Botulinic toxin was injected, without change. High levels of Tab were found, ATG 2723, ATPO 10.7. She started oral deflazacort 30 mg each 3 days, azathioprin 100 mg, daily. Actually, Tab levels are almost normal, but she remains with ocular alterations. Case 3: 56 year-old woman, Grave´s disease with exophtalmos in 1990, treated with I131 and immunosupression, with good outcome; obesity, hypertension and bilateral glaucoma in treatment. She suddenly presented diplopia and IV pair paresia of the right eye. A year later, ATb were found slightly elevated, ATG 100 years ATPO 227; despite prednisone 50 mg, each 3 days and azathioprin 150 mg/daily treatment, a surgical procedure was required for relieve the ocular symptoms. Results We found only 3 cases previously reported with this type of eye thyroid disease. Is important to note that awareness of this atypical form of orbitopathy

  4. 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)

    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.

    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

  8. 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)

    Autoimmune polyglandular syndrome is a constellation of signs and symptoms of simultaneous insufficiencies of several endocrine glands. Autoimmune polyglandular syndrome type 2 (APS 2) may be diagnosed when the adrenocortical insufficiency is associated with an autoimmune thyroid disease (Hashimoto's thyroiditis or Graves' disease), and/or insulin-dependent diabetes mellitus. Turner syndrome is the most common chromosomal disorder in females, caused by complete or partial X chromosome monosomy. We present the case of a 20-year-old woman with Turner syndrome, in whom APS 2 (Hashimoto's thyroiditis and adrenocortical insufficiency) has been diagnosed after introduction of recombinant human growth hormone (rhGH) therapy. In Turner syndrome, examination of the patient must regularly be conducted in order to diagnose a possible onset of autoimmune diseases; respective treatment must be applied as soon as the diagnosis is established. In particular, therapy of rhGH, used for short stature treatment, may be a trigger factor of adrenal insufficiency. The cortisol level in blood should be assessed before rhGH administration and carefully monitored during the therapy, especially in case of autoimmune thyroid disease coexistence. PMID:26071578

    A 49-yr-old woman presented with a solid, painless, nontender nodule in the left thyroid lobe. Thyroid scintigraphy revealed a solitary cold area in the left lobe and a slightly decreased 24-hr radioactive iodine thyroid uptake (9%). Although there were no specific clinical or biochemical signs suggesting thyroiditis needle aspiration cytology showed the presence of a subacute thyroiditis. Approximately 1 mo later the entire thyroid gland was affected leading to a completely suppressed thyroid radioiodine uptake and elevated serum thyroid hormone concentrations. This case illustrates that in the early phase of the disease, subacute thyroiditis may present as a solitary, painless, cold nodule and should be considered in the differential diagnosis of such lesions.

  12. 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.

    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.

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

    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.

    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.

    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.

    2006-01-01

    CONTEXT: Low birth weight has been proposed as a risk factor for the development of antibodies toward thyroid peroxidase (TPOAb) and thyroglobulin (TgAb) in adult life. However, the association could also be due to genetic or environmental factors affecting both birth weight and the development o...

  2. 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.)

Its function is to determine the amount of calories that the body has to burn to maintain normal weight. Thyroiditides are inflammatory processes that mainly result in autoimmune diseases. We have conducted the present study in order to have a clear picture of both autoimmune status and the control of body weight. We have evaluated the amount of either thyroid hormones, or antithyroid, or anti-microsomal, or anti-peroxidase antibodies (Abs in patients with high amounts of Abs. In a diet devoid of carbohydrates (bread, pasta, fruit, and rice, free from goitrogenic food, and based on body mass index, the distribution of body mass and intracellular and extracellular water conducted for 3 weeks gives the following results: patients treated as above showed a significant reduction of antithyroid (-40%, P<0.013, anti-microsomal (-57%, P<0.003, and anti-peroxidase (-44%, P<0,029 Abs. Untreated patients had a significant increase in antithyroid (+9%, P<0.017 and anti-microsomal (+30%, P<0.028 Abs. Even the level of anti-peroxidase Abs increased without reaching statistical significance (+16%, P>0064

  5. 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 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.

    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 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 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.

    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.

    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.

    Objective: To investigate the clinical significance of changes of serum thyroid peroxidase antibody (TPO-Ab) in patients with hyperthyroidism, hypothyroidism and simple goiter. Methods: Serum TPO-Ab, TMA,TGA and FT3, FT4, TSH levels were measured with radioimmunoassay(RIA) in 69 patients with hyperthyroidism, 53 patients with hypothyroidism, 45 patients with simple goiter and 20 controls. Results: The positive rate of thyroid peroxidase antibody (TPO-Ab) (82%-92.5%) was higher than that of thyroidglobulim antibody(TGA) (44.2%) and thyroid microsome antibody(TMA) (60.4-69.8%) in all patients with AICD. Conclusion: TPO-Ab could be taken as an important indicator in assessment of treatment and prognosis in patients with auto- immune thyroid diseases. (authors)

  14. Quantitative thyroid scintigraphy for the differentiation of Graves' disease and hyperthyroid autoimmune thyroiditis

    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.)

    Full Text Available Problem. Clinical features of Graves’ hyperthyroidism (GH generally improve during pregnancy and rebound in the postpartum period. It is unclear whether the ophthalmopathy that is associated with GH and, less often, Hashimoto’s thyroiditis (HT changes in parallel with the thyroid associated antibody reactions and clinical features or runs a different course. Method of Study. We retrospectively studied 19 patients with autoimmune thyroid disease over 22 pregnancies: 9 pregnancies with GH and 13 with HT. Ophthalmopathy was defined by NOSPECS class. Results. Thyroid peroxidase (TPO and thyroglobulin (Tg antibody titres decreased during pregnancy and rose in the postpartum period. During pregnancy, 5 patients with GH and 4 patients with HT developed mild ophthalmopathy and two patients with GH and HT developed new upper eyelid retraction (UER. In the postpartum period, eye scores improved in 3 patients with GH and 3 with HT, remained stable in two and 5 patients, respectively, and worsened in 2 patients with GH and one with HT. Conclusions. In patients with mild to moderate eye signs associated with GH and HT, the orbital and thyroid reactions ran different courses during pregnancy. Since no patient had severe ophthalmopathy, we cannot draw definitive conclusions from this preliminary study.

    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.

Such an autoimmune hepatopathy has been termed as hepatic overlap syndrome. Due to the autoimmune nature of the disease, associated diseases of other orga...

  20. 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

    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.

    Autoimmune diseases are considered the 3rd leading cause of morbidity and mortality in the industrialized countries. Autoimmune thyroid diseases (ATDs) are associated with high prevalence of nonorgan-specific autoantibodies, such as antinuclear antibodies (ANA), antidouble-stranded deoxyribonucleic acid (anti-dsDNA), antiextractable-nuclear antigens (anti-ENAs), rheumatoid factor (RF), and anticyclic-citrullinated peptides (anti-CCP) whose clinical significance is unknown.We aimed to assess the prevalence of various nonorgan-specific autoantibodies in patients with ATD, and to investigate the possible association between these autoantibodies and occurrence of rheumatic diseases and, if these autoantibodies could be considered as predictor markers for autoimmune rheumatic diseases in the future.This study had 2 phases: phase 1; in which 61 ATD patients free from rheumatic manifestations were assessed for the presence of these nonorgan-specific autoantibodies against healthy 61 control group, followed by 2nd phase longitudinal clinical follow-up in which cases are monitored systematically to establish occurrence and progression of any rheumatic disease in association to these autoantibodies with its influences and prognosis.Regarding ATD patients, ANA, anti-dsDNA, Anti-ENA, and RF were present in a percentage of (50.8%), (18%), (21.3%), and (34.4%), respectively, with statistically significance difference (P controls. Nearly one third of the studied group (32.8%) developed the rheumatic diseases, over 2 years follow-up. It was obvious that those with positive anti-dsDNA had higher risk (2.45 times) to develop rheumatic diseases than those without. There was a statistically significant positive linear relationship between occurrence of disease in months and (age, anti-dsDNA, anti-CCP, RF, and duration of thyroiditis). Anti-dsDNA and RF are the most significant predictors (P management of the disease, as early disease control will allow better quality of life. PMID

    B cells are centrally involved as antigen-presenting cells in certain autoimmune diseases. To establish whether autoantibodies form immune complexes (IC) with self-antigens in autoimmune thyroid disease (AITD) and promote B cell uptake of self-antigen, sera from patients with Hashimoto......'s thyroiditis (HT), Graves' disease (GD) and healthy controls were incubated with human thyroglobulin (Tg) before adding normal peripheral blood mononuclear cells. The deposition of immunoglobulins and C3 fragments on B cells was then assessed. Inclusion of Tg in serum from HT patients promoted B cell capture...... of IgG and C3 fragments. Furthermore, the binding of Tg to B cells in preparations of normal blood cells was higher in HT serum than in serum from controls and correlated positively with the serum anti-Tg activity, as did the B and CD4+ T cell proliferation.

    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

    @@ 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.

    Full Text Available The STAT4 gene encodes a transcriptional factor that transmits signals induced by several key cytokines which play important roles in the development of autoimmune diseases. The aim of this study was to explore the association of STAT4 polymorphism with Graves’ disease (GD and Hashimoto’s thyroiditis (HT. A total of 1048 autoimmune thyroid diseases (AITDs patients (693 with GD and 355 with HT and 909 age- and gender-matched controls were examined. STAT4 polymorphisms (rs7574865/rs10181656/ rs7572482 were genotyped by multiplex polymerase chain reaction (PCR and ligase detection reaction (LDR. The results indicated that the frequencies of rs7574865 genotypes in patients with GD differed significantly from the controls (p = 0.028, the T allele frequency of GD patients was also significantly higher than the controls (p = 0.020. The genotypes of rs10181656 differed significantly in GD patients from controls (p = 0.012; G allele frequencies were significantly higher in AITD patients than the controls (p = 0.014 and 0.031, respectively. The frequencies of haplotype GC with GD and HT patients were significantly lower than their controls (p = 0.015 and 0.030, respectively. In contrast, the frequencies of haplotype TG with GD and HT patients were significantly higher than their controls (p = 0.016 and 0.048, respectively. These findings strongly suggest that STAT4 rs7574865/rs10181656 polymorphisms increase the risk of AITD in a Chinese population.

  9. 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

    Full Text Available Background: Low 25(OH vitamin D levels have been associated with several autoimmune diseases and recently with autoimmune thyroiditis (AT. The aim of the study was to investigate the association of AT with low 25(OH vitamin D levels in the elderly. Methods: One hundred sixty-eight elderly subjects (mean age: 81.6 ± 9.4 years were enrolled. Serum levels of 25(OH vitamin D, anti-thyroid peroxidase (TPO-Ab, anti-thyroglobulin (TG-Ab antibodies, free triiodothyronine (FT3, free thyroxine (FT4 and thyroid stimulating hormone (TSH were measured. Results: The prevalence of AT was significantly higher in subjects with vitamin D deficiency (25(OH vitamin D < 20 ng/mL when compared with subjects with normal 25(OH vitamin D (25(OH vitamin D ≥ 20 ng/mL levels (28% vs. 8%, respectively, p = 0.002. Patients with AT and vitamin D deficiency had a comparable hormonal profile compared to patients with AT and vitamin D sufficiency in terms of TSH (p = 0.39, FT3 (p = 0.30, FT4 (p = 0.31, TG-Ab (0.44 and TPO-Ab (0.35. Interestingly, a significant correlation between 25(OH vitamin D and TPO-Ab (r = −0.27, p = 0.03 and FT3 (r = 0.35, p = 0.006 has been found in subjects with AT while no correlation was found between 25(OH vitamin D levels and TG-Ab (r = −0.15, p = 0.25, TSH (r = −0.014, p = 0.09 and FT4 (r = 0.13, p = 0.32. Conclusions: These findings suggest that vitamin D deficiency was significantly associated with AT in the elderly. Therefore, the screening for AT should be suggested in subjects with vitamin D deficiency.

  11. Activation of Helicobacter pylori causes either autoimmune thyroid diseases or carcinogenesis in the digestive tract.

    Astl, J; Šterzl, I

    2015-01-01

    Helicobacter pylori has been implicated in stimulation of immune system, development of autoimmune endocrinopathies as autoimmune thyroiditis (AT) and on other hand induction of immunosupresion activates gastric and extra-gastric diseases such as gastric ulcer or cancer. It causes persistent lifelong infection despite local and systemic immune response. Our results indicate that Helicobacter pylori might cause inhibition of the specific cellular immune response in Helicobacter pylori-infected patients with or without autoimmune diseases such as AT. We cannot also declare the carcinogenic effect in oropharynx. However the association of any infection agents and cancerogenesis exists. The adherence of Helicobacter pylori expression and enlargement of benign lymphatic tissue and the high incidence of the DNA of Helicobacter pylori in laryngopharyngeal and oropharyngeal cancer is reality. LTT appears to be a good tool for detection of immune memory cellular response in patients with Helicobacter pylori infection and AT. All these complications of Helicobacter pylori infection can be abrogated by successful eradication of Helicobacter pylori.

    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.

    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.

    Background: Thyroid autoimmunity is more common in females than in males. One possible explanation for this female preponderance may be the effect of oestrogens on the immune system. It has also been suggested that foetal microchimerism involving transfer of foetal cells into maternal tissue during...... pregnancy may play an important role. Objective: We investigated the association between the presence of circulating thyroid autoantibodies and previous pregnancy. parity and the use of oral contraceptives (OCs) and hormone replacement therapy (HRT) in a population cohort.

    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

  18. 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.

    Abstract Autoimmune diseases are considered the 3rd leading cause of morbidity and mortality in the industrialized countries. Autoimmune thyroid diseases (ATDs) are associated with high prevalence of nonorgan-specific autoantibodies, such as antinuclear antibodies (ANA), antidouble-stranded deoxyribonucleic acid (anti-dsDNA), antiextractable-nuclear antigens (anti-ENAs), rheumatoid factor (RF), and anticyclic-citrullinated peptides (anti-CCP) whose clinical significance is unknown. We aimed to assess the prevalence of various nonorgan-specific autoantibodies in patients with ATD, and to investigate the possible association between these autoantibodies and occurrence of rheumatic diseases and, if these autoantibodies could be considered as predictor markers for autoimmune rheumatic diseases in the future. This study had 2 phases: phase 1; in which 61 ATD patients free from rheumatic manifestations were assessed for the presence of these nonorgan-specific autoantibodies against healthy 61 control group, followed by 2nd phase longitudinal clinical follow-up in which cases are monitored systematically to establish occurrence and progression of any rheumatic disease in association to these autoantibodies with its influences and prognosis. Regarding ATD patients, ANA, anti-dsDNA, Anti-ENA, and RF were present in a percentage of (50.8%), (18%), (21.3%), and (34.4%), respectively, with statistically significance difference (P < 0.5) rather than controls. Nearly one third of the studied group (32.8%) developed the rheumatic diseases, over 2 years follow-up. It was obvious that those with positive anti-dsDNA had higher risk (2.45 times) to develop rheumatic diseases than those without. There was a statistically significant positive linear relationship between occurrence of disease in months and (age, anti-dsDNA, anti-CCP, RF, and duration of thyroiditis). Anti-dsDNA and RF are the most significant predictors (P < 0.0001). ATD is more associated with rheumatic

    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.

  3. 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.)

    Associations of autoimmune diseases with neurofibromatosis type 1 have been rarely described. In the present report, we describe two patients of neurofibromatosis type 1 having an association with vitiligo in one, and alopecia areata and autoimmune thyroiditis in another. The associations of neurofibromatosis type 1 with vitiligo, alopecia areata, and autoimmune thyroiditis have not been reported earlier. Whether these associations reflect a causal relationship with neurofibromatosis type 1 or are coincidental needs to be settled.

    HPS has been described in 9-20% of children with end-stage liver disease. We present a case of a previously, asymptomatic nine-yr-old incidentally found to have low oxygen saturation. Physical exam was remarkable for digital clubbing, splenomegaly and orthodeoxia. Laboratory evaluation revealed a low platelet count, hyperammonemia, and prolonged coagulation studies. Sonography showed evidence of splenomegaly and portal venous hypertension. High resolution CT thorax and CTA were normal. HPS was confirmed by agitated saline contrast enhanced echocardiography and Tc-99m MAA scan with evidence of intrapulmonary vascular dilatations. Liver biopsy was performed and consistent with autoimmune hepatitis. A high clinical index of suspicion should be maintained for HPS in pediatric patients who have unexplained hypoxemia as typical signs and symptoms of severe liver disease are often absent. In this report, we discuss a case of HPS complicated AIH in a pediatric patient and review the relevant literature. PMID:26992455

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

    2012-02-03

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

    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

    It has been twenty years since the first paper reporting the association between thyroid antibodies (TAIs) and spontaneous miscarriage was published. Following this observation, several studies have clearly demonstrated an increased prevalence of TAI in patients with recurrent miscarriage (RM). However, the exact mechanism underlying this association remains a matter of debate. The aim of the present study was to evaluate the thyroid function, throughout a specific test, in patient with RM and TAI focusing on the hypothesis that TAI should be an indirect sign of a mild thyroid dysfunction. 46 patients with RM and TAI were included in the study. All patients underwent short TRH stimulation test showing an abnormal response in the vast majority of cases (65%). Normal FT4 and FT3 mean values were found whereas TSH values were in the upper normal range (2.64 ± 1.3 mUI/L). Our data support the hypothesis that in patients with RM the presence of TAI is an indirect sign of a subtle thyroid dysfunction detectable by a specific test. This test give the possibility to identify women with RM in which specific therapeutic approaches could effectively improve the possibility for a successful pregnancy. PMID:22319528

  10. 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

    The coexistence of autoimmune hepatitis and juvenile idiopathic arthritis is very rare. This is the case of an 18 month old female patient whose first sign of disease was torticollis due to an underlying atlanto-axial subluxation. Three months later, bilateral knee arthritis developed and she was diagnosed with Juvenile Idiopathic Arthritis. Throughout the disease a persistent elevation of liver enzymes was noted, combined with positive antinuclear antibodies and hypergammaglobulinemia, reaching the diagnosis of concomitant autoimmune hepatitis.

    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.

    Studies documenting increased risk of developing autoimmune diseases (ADs) have shown that these conditions share several immunogenetic mechanisms (i.e., the autoimmune tautology). This report explored familial aggregation and segregation of AD, polyautoimmunity, and multiple autoimmune syndrome (MAS) in 210 families. Familial aggregation was examined for first-degree relatives. Segregation analysis was implemented as in S.A.G.E. release 6.3. Data showed differences between late- and early-onset families regarding their age, age of onset, and sex. Familial aggregation of AD in late- and early-onset families was observed. For polyautoimmunity as a trait, only aggregation was observed between sibling pairs in late-onset families. No aggregation was observed for MAS. Segregation analyses for AD suggested major gene(s) with no clear discernible classical known Mendelian transmission in late-onset families, while for polyautoimmunity and MAS no model was implied. Data suggest that polyautoimmunity and MAS are not independent traits and that gender, age, and age of onset are interrelated factors influencing autoimmunity. PMID:26697508

    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.

    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 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.

    The key to uncovering the etiology of hyperthyroidism lies in a careful history and physical examination. Autoimmune markers provide additive information, but should not solely be used to make a diagnosis. Concern has been raised that the overzealous use of thyroid ultrasound, following abnormal thyroid function tests, diverts attention from the workup of the biochemical abnormality to the workup of an incidentally found thyroid nodule. If further imaging is needed, the use ofathyroidscanhas been suggestedbythe Endocrine Society and the American Association of Clinical Endocrinologists. However, in certain scenarios, this may be contraindicated. We present the case of a 28-year-old female with hyperthyroidism, as aplatform to discuss an important clinical sign present on Doppler ultrasound of the thyroid. By recognizing the clinical information gained from a Doppler ultrasound, physicians can avoid additional invasive workup and apply the use of ultrasound where most appropriate.

    Introduction While extremely uncommon, diabetic ketoacidosis (DKA) and thyroid storm (TS) are endocrine emergencies that can coexist. We describe a case with a confounding clinical presentation that identifies these two emergencies within the setting of sepsis and influenza. Case A 69-year-old diabetic female was found by the paramedic staff to be disoriented. She demonstrated tachycardia and had a foul-smelling abdominal wound. Laboratory evaluation revealed DKA, leukocytosis, influenza B, and urinary tract infection. After appropriate management in the intensive care unit, the DKA resolved the following morning. However, the patient developed a fever, and her psychosis became more pronounced. Extensive analysis was performed but did not explain her mental status. The patient was found to have thyroid stimulating hormone of 0.06 mIU/mL, free T4 (thyroxine) of 2.38 ng/dL, and total T3 (triiodothyronine) of 72 ng/dL. Based on the Burch and Wartofsky criteria (score of 65), TS was diagnosed. Based on more recent diagnostic criteria suggested by Akamizu et al., the patient met criteria for TS grade 1. Within several hours of initiating treatment, the patient's mental state and tachycardia improved, and her psychosis resolved by the third day. Conclusion This case highlights the importance of recognizing the clinical diagnosis of TS, as the magnitude of thyroid hormone derangements may not correlate with clinical severity. While rare, DKA and TS can simultaneously occur and are associated with increased morbidity and mortality if not promptly recognized and treated. PMID:27609719

    Full Text Available Abstract Background In recent few years is underlined that altered balance of pro- and anti-inflammatory cytokines play an important role in the pathogenesis of AITD. The aim of this study was to estimate intracellular INF-γ and IL-4 levels in thyroid-infiltrating lymphocytes and thyrocytes isolated from thyroid tissues in 54 adolescent patients aged 8-21 years, with Graves' disease (GD; n = 18, Hashimoto's thyroiditis (HT; n = 18 and non-toxic multinodular goiter (NTMG; n = 18. Methods Fresh thyroid tissues were taken on culture medium RPMI -1640, it was mechanically prepared. In next step were added cell activators -12- myristate 13- the acetate (PMA and Ionomycin as well as the inhibitor of transportation of proteins - Breferdin A. 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.

    Thyroid carcinoma is usually indolent with good prognosis, as compared to other malignancy. Distant metastases from thyroid cancer are rare and usually manifest as multiple lesions especially in lungs, bones and lymph nodes, in advanced stages of the disease. Metastasis to the breast from thyroid carcinoma is extremely rare, with about 16 cases reported in the English literature. Herein, we reported a case of metastatic poorly differentiated thyroid carcinoma, which presented as 2 breast masses in a 72-year-old woman, 6 years after total thyroidectomy for papillary thyroid carcinoma. Although the computed tomography (CT) and ultrasonography (USG) image findings are nonspecific oval mass with circumscribed or partially indistinct margin, metastases from thyroid cancer should be included in the differential diagnosis when recurrence of thyroid carcinoma is suspected. Also, fusion images of CT and USG are helpful to the radiologists in localizing the targeted lesion and conducting accurate USG-guided biopsy.

    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.

    Full Text Available Aim. This study aimed to compare thyroid functions, thyroid autoantibodies, and the existence of nonthyroidal illness syndrome (NTIS according to vitamin D level. Materials and Methods. The study included age- and BMI-matched healthy volunteers with and without vitamin D deficiency. In addition, the nonthyroidal illness syndrome status was evaluated. Results. Anti-TPO positivity was significantly more common in those with severe and moderate vitamin D deficiency, as compared to those with a normal 25(OHD level. Furthermore, TSH levels were significantly lower in those with severe and moderate vitamin D deficiency than in those with a normal 25(OHD level. In addition, there was a significant weak inverse correlation between anti-TPO positivity and the 25(OHD level and a positive correlation between the TSH level and 25(OHD level. Only 1 thyroid function test result was compatible with NTIS among the participants with moderate vitamin D deficiency; therefore the difference was not significant. Conclusions. The prevalence of thyroid autoantibody positivity was higher in those with severe and moderate vitamin D deficiency than in those with a normal 25(OHD level. Additional large-scale studies must be conducted to determine if vitamin D deficiency plays a causal role in the pathogenesis of Hashimoto’s thyroiditis and NTIS.

    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.

    Full Text Available Type 1 diabetes (T1D in children and adolescents is relatively often accompanied by other immunopathological diseases, autoimmune thyroid disease (AITD or celiac disease (CD. 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.

    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 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.

  20. CASE OF SUBACUTE THYROIDITIS PRESENTING AS THE CAUSE OF PYREXIA OF UNKNOWN ORIGIN

    Full Text Available : Pyrexia of unknown origin (PUO is not infrequently a diagnostic dilemma for clinicians. Endocrine causes of PUO are rare. The endocrine disorder likely to present as PUO is subacute thyroiditis. Subacute thyroiditis usually occurs in middle-aged women as viral prodrome, classic symptoms of thyrotoxicosis, and an elevated erythrocyte sedimentation rate. The patient may have abrupt onset of fever and chills with complaints of thyroid pain, or only low-grade fever with poorly characterized anterior neck pain. We present a case of PUO in a 40-year-old male who had fever for more than two month. Despite an extensive evaluation, the patient had persistent fever and no cause was found, with the exception of subacute thyroiditis. The fever resolved from the fifth day of treatment with low-dose steroid (Prednisolone, 10mg per day. This case illustrates that subacute thyroiditis should be considered in cases of FUO.

    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

    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.

    Autoimmune thyroid diseases (AITD) and Type 1 diabetes (T1D) frequently occur in the same individual pointing to a strong shared genetic susceptibility. Indeed, the cooccurrence of T1D and AITD in the same individual is classified as a variant of the autoimmune polyglandular syndrome type 3 (designated APS3v). Our aim was to identify new genes and mechanisms causing the co-occurrence of T1D+AITD (APS3v) in the same individual using a genome-wide approach. For our discovery set we analyzed 346 Caucasian APS3v patients and 727 gender and ethnicity matched healthy controls. Genotyping was performed using the Illumina Human660W-Quad.v1. The replication set included 185 APS3v patients and 340 controls. Association analyses were performed using the PLINK program, and pathway analyses were performed using the MAGENTA software. We identified multiple signals within the HLA region and conditioning studies suggested that a few of them contributed independently to the strong association of the HLA locus with APS3v. Outside the HLA region, variants in GPR103, a gene not suggested by previous studies of APS3v, T1D, or AITD, showed genome-wide significance (p<5×10−8). In addition, a locus on 1p13 containing the PTPN22 gene showed genome-wide significant associations. Pathway analysis demonstrated that cell cycle, B-cell development, CD40, and CTLA-4 signaling were the major pathways contributing to the pathogenesis of APS3v. These findings suggest that complex mechanisms involving T-cell and B-cell pathways are involved in the strong genetic association between AITD and T1D. PMID:25936594

    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.

  12. 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)

    Abstract Hashimoto's thyroiditis is the most common diffuse thyroid disease and is characterized by diffuse lymphocytic infiltration. However, the ultrasonographic findings of papillary thyroid carcinomas that arise from Hashimoto's thyroiditis in the pediatric and adolescent population are not well known. We report a rare ultrasonographic finding in a 22-year-old woman diagnosed with the diffuse sclerosing variant of papillary thyroid carcinoma that arose from underlying Hashimoto's thyroiditis: innumerable diffuse microcalcifications instead of a typical malignant-appearing nodule.

    Cervical cord compression secondary to extension of a long standing papillary thyroid carcinoma as well as multiple cases of distal cord compression from occult follicular thyroid carcinoma have been reported. But cervical cord compression from Papillary Thyroid Carcinoma has not been reported so far. Forty eight year old lady presented with progressive quadriparesis of 2 months duration. MRI of the cervical spine showed destructive lesion with soft tissue component in vertebral bodies and posterior elements of C4-C6 vertebrae with cord compression along with a large thyroid mass extending to retrosternal region likely malignant. USG guided FNAC & Biopsy of thyroid lesion was inconclusive. She underwent Preoperative Selective angioembolisation for vertebral metastasis followed by total thyroidectomy with cervical cord decompression, bone grafting and plating. HPE reported follicular variant of Papillary Thyroid carcinoma. Four weeks postoperatively she underwent radioiodine ablation by 263 mci of I 131. She then received palliative EBRT to cervical and dorsal spine 30 Gy/10 fractions. She is alive and neurologically stable at 6 months follow up. Papillary thyroid carcinoma has an excellent prognosis. Hence a prompt management of primary disease and aggressive approach to metastatic lesion may prolong survival and allow favorable prognosis.

    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.

    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.

    We present a 25-year-old woman with amyloid goiter due to hypersensitivity vasculitis, who developed transient thyrotoxicosis resembling subacute thyroiditis. She received prednisolone (20 mg/ day) for three years for hypersensitivity vasculitis, and was diagnosed as having secondary amyloidosis by biopsies of the stomach, rectum and kidneys. She noticed neck swelling with severe right neck tenderness, palpitation, hyperhidrosis and weight loss. An elastic firm diffuse goiter was palpable, and the upper pole of the right lobe was extremely tender. Her serum free T4 and T3 levels were high, and the serum TSH was suppressed to subnormal. She was positive for serum C-reactive protein. Anti-thyroidal autoantibodies were all negative. Her thyrotoxicosis subsided spontaneously within one week. Serum titers of antibodies to various viruses were unchanged during the clinical course for two weeks, but she was positive for HLA B35. Examination of a needle-biopsy specimen of the thyroid gland showed extensive amyloid deposition and no evidence of subacute thyroiditis. We considered her transient thyrotoxicosis to be associated with amyloid goiter. The clinical course of this case was similar to the subacute thyroiditis-like syndrome, first described by Ikenoue et al. When patients with primary or secondary amyloidosis have symptoms and signs of subacute thyroiditis, but develop an unusual course, amyloid goiter should be considered. PMID:9790279

    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.

  4. 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)

    2016-01-01

    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

    Objective To describe clinical characteristics and immunotherapy responses in patients with autoimmune epilepsy. Design Observational, retrospective case series. Setting Mayo Clinic Health System. Patients Thirty-two patients with an exclusive (n=11) or predominant (n = 21) seizure presentation in whom an autoimmune etiology was suspected (on the basis of neural autoantibody [91%], inflammatory cerebrospinal fluid [31%], or magnetic resonance imaging suggesting inflammation [63%]) were studied. All had partial seizures: 81% had failed treatment with 2 or more anti-epileptic drugs and had daily seizures and 38% had seizure semiologies that were multifocal or changed with time. Head magnetic resonance imaging was normal in 15 (47%) at onset. Electroencephalogram abnormalities included interictal epileptiform discharges in 20; electrographic seizures in 15; and focal slowing in 13. Neural autoantibodies included voltage-gated potassium channel complex in 56% (leucine-rich, glioma-inactivated 1 specific, 14; contactin-associated proteinlike 2 specific, 1); glutamic acid decarboxylase 65 in 22%; collapsin response-mediator protein 5 in 6%; and Ma2, N-methyl-D-aspartate receptor, and ganglionic acetylcholine receptor in 1 patient each. Intervention Immunotherapy with intravenous methylprednisolone; intravenous immune globulin; and combinations of intravenous methylprednisolone, intravenous immune globulin, plasmapheresis, or cyclo-phosphamide. Main Outcome Measure Seizure frequency. Results After a median interval of 17 months (range, 3–72 months), 22 of 27 (81%) reported improvement postimmunotherapy; 18 were seizure free. The median time from seizure onset to initiating immunotherapy was 4 months for responders and 22 months for nonresponders (P<.05). All voltage-gated potassium channel complex antibody–positive patients reported initial or lasting benefit (P<.05). One voltage-gated potassium channel complex antibody–positive patient was seizure free after

  8. The Study on the Thyroid Disease

    International Nuclear Information System (INIS)

    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, T3, 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.

    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.

    2016-01-01

    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.

    2015-01-01

    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.

  13. 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

    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

    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 pancreatitis(AIP) is part of a systemic fibrosclerotic process characterized by lymphoplasmacytic infiltrate with immunoglobulin G subtype-4(Ig G4) positive cells. It characteristically presents with biliary obstruction due to mass-like swelling of the pancreas. Frequently AIP is accompanied by extra-pancreaticmanifestations including retroperitoneal fibrosis, thyroid disease, and salivary gland involvement. Auto-antibodies, hypergammaglobulemia, and prompt resolution of pancreatic and extrapancreatic findings with steroids signify its autoimmune nature. Refractory cases are responsive to immunomodulators and rituximab. Involvement of the biliary tree, termed IgG 4 associated cholangiopathy, mimics primary sclerosing cholangitis and is challenging to manage. High IgG 4 levels and swelling of the pancreas with a diminutive pancreatic duct are suggestive of autoimmune pancreatitis. Given similarities in presentation but radical differences in management and outcome, differentiation from pancreatic malignancy is of paramount importance. There is controversy regarding the optimal diagnostic criterion and steroid trials to make the diagnosis. Additionally, the retroperitoneal location of the pancreas and requirement for histologic sampling, makes tissue acquisition challenging. Recently, a second type of autoimmune pancreatitis has been recognized with similar clinical presentation and steroid response though different histology, serologic, and extrapancreatic findings.

    2016-01-01

    Etiologies of a thickened stalk include inflammatory, neoplastic, and idiopathic origins, and the underlying diagnosis may remain occult. We report a patient with a thickened pituitary stalk (TPS) and papillary thyroid carcinoma (PTC) whose diagnosis remained obscure until a skin lesion appeared. The patient presented with PTC, status postthyroidectomy, and I131 therapy. PTC molecular testing revealed BRAF mutant (V600E, GTC>GAG). She had a 5-year history of polyuria/polydipsia. Overnight dehydration study confirmed diabetes insipidus (DI). MRI revealed TPS with loss of the posterior pituitary bright spot. Evaluation showed hypogonadotropic hypogonadism and low IGF-1. Chest X-ray and ACE levels were normal. Radiographs to evaluate for extrapituitary sites of Langerhans Cell Histiocytosis (LCH) were unremarkable. Germinoma studies were negative: normal serum and CSF beta-hCG, alpha-fetoprotein, and CEA. Three years later, the patient developed vulvar labial lesions followed by inguinal region skin lesions, biopsy of which revealed LCH. Reanalysis of thyroid pathology was consistent with concurrent LCH, PTC, and Hashimoto's thyroiditis within the thyroid. This case illustrates that one must be vigilant for extrapituitary manifestations of systemic diseases to diagnose the etiology of TPS. An activating mutation of the protooncogene BRAF is a potential unifying etiology of both PTC and LCH. PMID:27656301

    2013-01-01

    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

    2011-01-01

    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.

    1999-11-01

    This review summarizes the current status of intravenous immunoglobulin (IVIg) in the treatment of autoimmune neuromuscular disorders and the possible mechanisms of action of the drug based on work in vivo, in vitro, and in animal models. Supply of idiotypic antibodies, suppression of antibody production, or acceleration of catabolism of immunoglobulin G (IgG) are relevant in explaining the efficacy of IVIg in myasthenia gravis (MG), Lambert-Eaton myasthenic syndrome (LEMS), and antibody-mediated neuropathies. Suppression of pathogenic cytokines has putative relevance in inflammatory myopathies and demyelinating neuropathies. Inhibition of complement binding and prevention of membranolytic attack complex (MAC) formation are relevant in dermatomyositis (DM), Guillain-Barré syndrome (GBS), and MG. Modulation of Fc receptors or T-cell function is relevant in chronic inflammatory demyelinating polyneuropathy (CIDP), GBS, and inflammatory myopathies. The clinical efficacy of IVIg, based on controlled clinical trials conducted in patients with GBS, CIDP, multifocal motor neuropathy (MMN), DM, MG, LEMS, paraproteinemic IgM anti-myelin-associated glycoprotein (anti-MAG) demyelinating polyneuropathies, and inclusion body myositis is summarized and practical issues related to each disorder are addressed. The present role of IVIg therapy in other disorders based on small controlled or uncontrolled trials is also summarized. Finally, safety issues, risk factors, adverse reactions, spurious results or serological tests, and practical guidelines associated with the administration of IVIg in the treatment of neuromuscular disorders are presented.

    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

    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

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.

    T-cell tolerance to self-antigens is established in the thymus through the recognition by developing thymocytes of self-peptide-MHC complexes and induced and maintained in the periphery. Efficient negative selection of auto-reactive T cells in the thymus is dependent on the in situ expression of both ubiquitous and tissue-restricted self-antigens and on the presentation of derived peptides. Weak or inadequate intrathymic expression of self-antigens increases the risk to generate an autoimmune-prone T-cell repertoire. Indeed, even small changes of self-antigen expression in the thymus affect negative selection and increase the predisposition to autoimmunity. Together with other mechanisms, tolerance is maintained in the peripheral lymphoid organs via the recognition by mature T cells of a similar set of self-peptides in homeostatic conditions. However, non-lymphoid peripheral tissue, where organ-specific autoimmunity takes place, often have differential functional processes that may lead to the generation of epitopes that are absent or non-presented in the thymus. These putative differences between peptides presented by MHC molecules in the thymus and in peripheral tissues might be a major key to the initiation and maintenance of autoimmune conditions.

    Full Text Available Background. Pemphigus vulgaris is an autoimmune vesiculobullous disease, affecting the skin and mucous membranes. It is reported to be associated with other autoimmune diseases including autoimmune thyroid diseases. However we report herein a case of pemphigus vulgaris associated with autonomous toxic nodule. Case Presentation. A 51-year-old woman was evaluated for blisters and erosions that develop on her trunk, face, and extremities, with a five-year history of progressively enlarging neck mass, and a past medical history of pemphigus vulgaris seven years ago. The condition was associated with palpitation, dyspnea, and heat intolerance. Thyroid function tests and thyroid scan were compatible with the diagnosis of thyrotoxicosis due to autonomous toxic nodule. Exacerbation of pemphigus vulgaris was proved by skin biopsy from the patient which revealed histologic picture of pemphigus vulgaris. Conclusion. Autoimmune thyroid diseases are reported to associate pemphigus vulgaris. To our knowledge, this case is the first in the English literature to report association between pemphigus vulgaris and autonomous toxic nodule and highlights the possibility of occurrence of pemphigus vulgaris with a nonautoimmune thyroid disease raising the question: is it just a coincidence or is there an explanation for the occurrence of both conditions together?

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.

    Autoimmune thyroid disease (AITD) is associated with breast cancer closely. It is shown that patients with AITD, especially those with lower free T4, are prone to having breast cancer. The positive rate of thyroid antibody is a distinguishing marker between benign with malignant nodules, and also a marker of the breast cancer prognosis. Thyroid uhrasonography can help to diagnose AITD in patients with breast cancer, also to predict the prognosis of breast cancer. The mechanisms of breast cancer accompanying with AITD are unclear, maybe include some common physiological bases in thyroid and breast, such as iodic trans-fer (sodium iodide symporter, NIS), the effect of TRH and part anterior pituitary hormones;deficiency of io-dide;immune abnormalities representing by chemokine CXCL10. It is suggests that radioiodine(targeting NIS in breast) and some immune drugs( targeting Ras and CXCL10/CXCR3 )hold promise for the new treatment of breast cancer.%自身免疫性甲状腺疾病(AITD)与乳腺癌密切相关,AITD尤其是低游离T4(FT4)患者易发生乳腺癌.甲状腺抗体阳性率是鉴别良、恶性乳腺结节、预测乳腺癌转归的标志.甲状腺B超可诊断乳腺癌患者是否合并AITD,也可预测乳腺癌的转归.其确切机制还不清楚,可能涉及甲状腺和乳腺存在某些相同的生理基础,如碘转运(钠/碘转运体,NIS)、促甲状腺激素释放激素(TRH)及部分垂体前叶激素的作用;碘缺乏;以趋化因子CXCL10为代表的免疫异常.靶点为乳腺细胞中NIS的放射性碘治疗、作用于Ras和CXCL10/CXCR3的免疫调节药物在未来都可能成为治疗乳腺癌的新手段.

    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

    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.

    2013-01-01

    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.

    近年来较多的研究表明,维生素D具有调节免疫的特性,在一些自身免疫性疾病动物模型中表现出一定的防治作用.自身免疫性甲状腺疾病(AITD)是一种器官特异性自身免疫性疾病.研究证实,维生素D相关基因多态性与AITD相关,如维生素D受体基因、1α-羟化酶(CYP2781)基因、维生素D结合蛋白基因等.AITD患者存在维生素D缺乏,一些研究表明应用维生素D对AITD具有一定的防治作用.维生素D及其类似物防治AITD的可能机制在于它们能够调节AITD患者的细胞因子表达,并对其甲状腺细胞凋亡具有调节作用.因此认为,维生素D及其类似物在AITD的临床应用前景广阔.%In recent years,the role of vitamin D in the immune system has been investigated. The immunomodulatory properties of vitamin D compounds were illustrated by their ability to either prevent or suppress animal models of autoimmune disease. Autoimmune thyroid diseases (AITD) are organ-specific an-toimmune diseases. It was testified that AITD were associated with the polymorphisms of vitamin D related genes, such as vitamin D receptor gene,25-hydroxyvitamin D3-1α-hydroxylase (CYP27B1) gene, vitamin D-binding protein gene, etc. Patients with AITD were coexisted with vitamin D deficiency and vitamin D supple-mentation benefited for the prevention and treatment of AITD. The probable mechanisms of vitamin D and its analogs in AITD maybe include modulating the expression of many cytokines in AITD and regulating apopto-sis of thyroid cells. Thus we postulate that vitamin D and its analogs have a broad prospect in the clinical ap-plication for AITD.

    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

    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.

    Warthin-like Papillary thyroid carcinoma (WPTC) is a rare variant of papillary carcinoma of thyroid, PTC which derives its name by closely resembling Warthin's tumor of salivary gland. Hallmark histological feature of this variant is papillary folding lined by oncocytic neoplastic cells with clear nuclei and nuclear pseudoinclusions, accompanied by prominent lymphocytic infiltrate in the papillary stalks. It is thought to be one of those differentiated thyroid cancers with favorable prognosis. We report a case of Graves' disease with a cold nodule harboring WPTC with initial presentation of lymph nodal metastases. It is important to identify this peculiar variant of PTC as 5 to 10% of them undergo dedifferentiation and 30% have the lymph nodal metastases and extra thyroidal extension.

    Thyroid dysfunction may impair fertility, course of pregnancy and fetal development. Physiological alterations of thyroid function parameters, that occur during pregnancy need to be distinguished from pathophysiological states of hypo- and hyperthyroidism. We performed a literature search (PubMed 1990-2013) and review relevant publications as well as consensus and practice guidelines of international thyroid/endocrine societies. Interpretation of thyroid function values in pregnancy must be based on trimester-specific TSH and T4 ranges. Alterations in thyroid function are present in up to 15% of pregnancies (0.4% overt hypothyroidism, 0.1-0.4% hyperthyroidism) and may lead to preventable complications in the pregnant woman and the fetus. Hypothyroidism is associated with an increased risk for abortion, premature delivery and stillbirth, besides impairment of neurocognitive development. The latter has also been shown in situations of grave iodine deficiency. In addition to new-born screening directed at early recognition of congenital hypothyroidism (incidence 0.03%), universal screening of all pregnant women should be implemented in health care guidelines. Newly diagnosed overt hypothyroidism in a pregnant woman requires immediate levothyroxine substitution at adequate doses. In subclinical hypothyroidism thyroid hormone replacement should be considered. Iodine supplementation is strongly recommended in all pregnant and breast-feeding women. Pregnancy causes a number of, that need to be of thyroid dysfunction. Both hypothyroidism and thyrotoxicosis may impair the course of pregnancy and may negatively affect the fetus. In particular, maternal hypothyroidism may lead to irreparable and detrimental deficits in the neurocognitive development of the fetus. Autoimmune thyroid disease is the most common cause of thyroid dysfunction in pregnancy. Hashimoto's thyroiditis is associated with impaired fertility and miscarriage, and may first manifest in pregnancy due to the

    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.

    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

    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

    2013-06-01

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

    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

    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

  18. 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

    The prevalence of post-partum thyroiditis (PPT) has been reported in several countries (1.9 to 16.7%) but is not known in Brazil. Several factors have been associated to its development, such as a female sex of the newborn, PPT in a previous pregnancy, a family history of thyroid disease and cigarette smoking. To investigate the prevalence of PPT and its risk factors in a southern Brazilian city, a three-cross-sectional observation study was performed. PPT was diagnosed in 14/284 subjects (5.3%) and all cases had thyrotoxicosis (13 sub-clinical and one clinical). Serum total T4 and free T4 were higher and serum TSH was lower in PPT subjects. Anti-thyroid antibodies were positive in 16.7% of PPT subjects and in 4.5% of those with no thyroid dysfunction. Goiter was identified in 14.3% of PPT subjects and in 15% of no PPT subjects. Thyroid was hardened more frequently in PPT subjects (21.4%) than in others (5.2%). Male sex of the newborn was associated to PPT, increasing 11 times the risk of PPT. Cigarette smoking was associated to PPT in group II subjects. There was no clinical sign or symptom able to contribute to this diagnosis, except the presence of hardened thyroid. Based on these findings, PPT, manifesting itself as mild thyrotoxicosis, is a common problem in southern Brazil and is associated to male sex of the newborn. PMID:11021764

He denied ocular pain, diplopia or change in the prominence of one or both eyes. Examination revealed 2 mm of relative proptosis on the right, bilateral temporal flare and lower lid retraction. There was minimal upper lid retraction and no evidence of lid lag. Ocular motility was full. Dilated fundoscopic examination revealed bilateral optic nerve edema, right more than left. CT of the orbit demonstrated enlargement of the extraocular muscles bilaterally with marked enlargement of the right medial rectus and left inferior rectus muscles resulting in crowding at the orbital apex bilaterally. Laboratory testing revealed the patient to be hyperthyroid. The patient was treated with high dose oral steroids followed by orbital radiation. Hyperthyroidism was managed by the patient's primary care physician. Visual symptoms rapidly improved with oral steroids and orbital radiation. Optic nerve edema completely resolved. Repeat CT imaging demonstrated a reduction in the enlargement of the extraocular muscles with relief of bilateral optic nerve compression.

    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 ...

    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.

    T cells specific for nucleosomal autoepitopes are selectively expanded in lupus mice and these Th cells drive autoimmune B cells to produce pathogenic antinuclear antibodies. We transfected the TCR-alpha and -beta chain genes of a representative, pathogenic autoantibody-inducing Th clone specific for the nucleosomal core histone peptide H471-94 into TCR-negative recipient cells. Although the autoimmune TCRs were originally derived from SNF1 (I-Ad/q) mice, the transfectants could recognize the nucleosomal autoepitope presented by APC-bearing I-A molecules of all haplotypes tested, as well as human DR molecules. Competition assays indicated that the autoepitopes bound to the MHC class II groove. Most remarkably, MHC-unrestricted recognition of the nucleosomal peptide epitope was conferred by the lupus TCR-alpha chain even when it paired with a TCR-beta chain of irrelevant specificity. Several other disease-relevant Th clones and splenic T cells of lupus mice had similar properties. The TCR-alpha chains of these murine lupus Th clones shared related motifs and charged residues in their CDRs, and similar motifs were apparent even in TCR-alpha chains of human lupus Th clones. The lupus TCR-alpha chains probably contact the nucleosomal peptide complexed with MHC with relatively high affinity/avidity to sustain TCR signaling, because CD4 coreceptor was not required for promiscuous recognition. Indeed, pathogenic autoantibody-inducing, CD4-negative, TCR-alphabeta+ Th cells are expanded in systemic lupus erythematosus. These results have implications regarding thymic selection and peripheral expansion of nucleosome-specific T cells in lupus. They also suggest that universally tolerogenic epitopes could be designed for therapy of lupus patients with diverse HLA alleles. We propose to designate nucleosomes and other antigens bearing universal epitopes "Pantigens" (for promiscuous antigens).

    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.

    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.

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.

    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.

  19. 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

    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.

  2. Recurrent pregnancy loss in patients with thyroid dysfunction

    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.

AITD is a common disorder affecting primarily women, and both genetic and environmental factors are included in its pathogenesis. DM is considered an autoimmune disease of the muscles and skin. Although AITD is the most common cause of hypothyroidism, to the best of our knowledge, only three cases of DM and AITD in the same patient have been reported in the last 40 years. We consider that both are developed from the same autoimmune background. Herein, we present a case of a 30-year-old man with a 4-year history of AITD who was diagnosed as suffering as well from DM.

    Sclerosing lymphocytic lobulitis (SLL) is a rare inflammatory disorder, which is also known as fibrous mastopathy and lymphocytic mastitis. It is commonly associated with autoimmune disorders, particularly type 1 diabetes and thyroiditis. We report the case of a 28-year-old woman diagnosed as SLL with Hashimoto's thyroiditis, but without diabetes. She presented suspicious microcalcifications without palpable mass in routine mammograms in both breasts. She had been diagnosed as Hashimoto's thyroiditis several years before and had been followed up in endo-clinics. PMID:23834442

    Objective To investigate the salivary gland function changes in patients with autoimmune thyroid disease. Methods Thirty five patients with Graves' disease (7 males and 28 females,aged 49.62 ± 11.10y), 15 patients with Hashimoto thyroiditis (5 males and 10 females,aged 45.67 ± 9.85 y )and 35 age- and sex-matched healthy subjects were included in the study. All subjects underwent routine thyroid scintigraphy imaging and salivery gland dynamic imaging. Time - activity curve of bilateral parotids and bilateral submandibulars were obtained by outlining regions of interest (ROI) of these glands,excreting technetium rate (ex%) and excreting technetium time (Tex) of each gland were calculated. Results The excreting technetium function of major salivary glands decreased significantly in Graves' disease patients(P<0.05). The excreting technetium function in major salivary glands of Hashimoto thyroiditis decreased significantly(P<0.05). The time of excreting technetium of major salivary gland was not longer than that of normal controls. The major salivary gland function was not correlated with thyroid technetium uptake rate at 30min in Graves' disease patients (r= -0.1768,-0.2753,-0.2596,-0.1747; P= 0.3331,0.1299,0.1514,0.3388). Conclusion With salivary gland dynamic imaging during routine thyroid scintigraphy, thyroid function parameters and salivary gland function indicators can be obtained simultaneously.%目的 通过在自身免疫性甲状腺疾病患者甲状腺显像过程中加入唾液腺显像,旨在探讨自身免疫性甲状腺疾病患者唾液腺功能的改变,以便指导临床在治疗此类疾病过程中同时关注患者唾液腺功能.方法 选取35 例Graves 病患者,15 例桥本甲状腺炎和同期同年龄唾液腺功能正常者35例.Graves 病及桥本甲状腺炎患者在甲状腺显像同时进行唾液腺显像.在甲状腺显像注射显像剂后常规等待的30min 行唾液腺动态显像,通过勾画ROI,获得

    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

    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).

    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.

    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.

    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. Autoimmune disease classification by inverse association with SNP alleles.

    2009-12-01

    Full Text Available With multiple genome-wide association studies (GWAS performed across autoimmune diseases, there is a great opportunity to study the homogeneity of genetic architectures across autoimmune disease. Previous approaches have been limited in the scope of their analysis and have failed to properly incorporate the direction of allele-specific disease associations for SNPs. In this work, we refine the notion of a genetic variation profile for a given disease to capture strength of association with multiple SNPs in an allele-specific fashion. We apply this method to compare genetic variation profiles of six autoimmune diseases: multiple sclerosis (MS, ankylosing spondylitis (AS, autoimmune thyroid disease (ATD, rheumatoid arthritis (RA, Crohn's disease (CD, and type 1 diabetes (T1D, as well as five non-autoimmune diseases. We quantify pair-wise relationships between these diseases and find two broad clusters of autoimmune disease where SNPs that make an individual susceptible to one class of autoimmune disease also protect from diseases in the other autoimmune class. We find that RA and AS form one such class, and MS and ATD another. We identify specific SNPs and genes with opposite risk profiles for these two classes. We furthermore explore individual SNPs that play an important role in defining similarities and differences between disease pairs. We present a novel, systematic, cross-platform approach to identify allele-specific relationships between disease pairs based on genetic variation as well as the individual SNPs which drive the relationships. While recognizing similarities between diseases might lead to identifying novel treatment options, detecting differences between diseases previously thought to be similar may point to key novel disease-specific genes and pathways.

    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.

    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

    2005-01-01

    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

    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

    Physiological changes during gestation and after delivery are associated with postpartum thyroid dysfunction, which is due to thyroid autoimmunity in some cases. Postpartum thyroid dysfunction, in turn, has been associated with postpartum depression (PPD). The aim of the present study was to evaluate whether thyroid function immediately after delivery can predict postpartum depression at 8 weeks and 32 weeks after delivery. This study examined 1053 postpartum Spanish women without a previous history of depression. We evaluated depressive symptoms at 48h, 8 weeks and 32 weeks postpartum and used a diagnostic interview to confirm major depression for all probable cases. Free thyroxin (fT4), thyroid-stimulating hormone (TSH), thyroid peroxidase antibodies (TPOAb) and C-reactive protein (CRP) were assayed at 48h postpartum. Binary and multivariate logistic regression analyses were performed to determine independent risk factors for PPD. Although 152 women (14.4%) had high TPOAb (>27IU/mL) and slightly elevated TSH concentrations with normal fT4, we did not find any association between thyroid function and PPD. This thyroid dysfunction was not associated with CRP concentrations that were outside of the normal range (>3mg/L). We conclude that thyroid function at 48h after delivery does not predict PPD susceptibility. PMID:19939574

    Despite the fact that epilepsy is the third most common chronic brain disorder, relatively little is known about the processes leading to the generation of seizures. Accumulating data support an autoimmune basis in patients with antiepileptic drug-resistant seizures. Besides, recent studies show that epilepsy and autoimmune disease frequently co-occur. Autoimmune epilepsy is increasingly recognized in the spectrum of neurological disorders characterized by detection of neural autoantibodies in serum or spinal fluid and responsiveness to immunotherapy. An autoimmune cause is suspected based on frequent or medically intractable seizures and the presence of at least one neural antibody, inflammatory changes indicated in serum or spinal fluid or on MRI, or a personal or family history of autoimmunity. It is essential that an autoimmune etiology be considered in the initial differential diagnosis of new onset epilepsy, because early immunotherapy assures an optimal outcome for the patient.

    Autoimmune hepatitis is an unresolving, hepatocellular inflammation of unknown cause that is characterized by the presence of periportal hepatitis on histologic examination, tissue autoantibodies in serum, and hypergammaglobulinemia. By international consensus, the designation autoimmune hepatitis has replaced alternative terms for the condition. Three types of autoimmune hepatitis have been proposed based on immunoserologic findings. Type 1 autoimmune hepatitis is characterized by the presence of antinuclear antibodies (ANA) or smooth muscle antibodies (SMA) (or both) in serum. Seventy percent of patients with type 1 of autoimmune hepatitis are women. This type is the most common form and accounts for at least 80% of cases. Type 2 is characterized by the presence of antibodies to liver-kidney microsome type 1 (anti-LKM1) in serum. Patients with this type of autoimmune hepatitis are predominantly children. Type 3 autoimmune hepatitis is characterized by the presence of antibodies to soluble liver antigen (anti-SLA) in serum. There are no individual features that are pathognomonic of autoimmune hepatitis, and its diagnosis requires the confident exclusion of other conditions. The large majority of patients show satisfactory response to corticosteroid (usually prednisone or prednisolone) therapy. For the past 30 years it has been customary to add azathioprine as a "steroid sparing" agent to allow lower doses of steroids to be used and remission, once achieved, can be sustained in many patients with azathioprine alone after steroid withdrawal. Patients with autoimmune hepatitis who have decompensated during or after corticosteroid therapy are candidates for liver transplantation.

    In this article, we review the incidence and significance of seizures in well-established autoimmune disorders, including multiple sclerosis (MS), diabetes mellitus, celiac disease, thyroid disease, and systemic lupus erythematosus (SLE). The five following presentations discuss the incidence and possible pathogenesis of epilepsies that are found in these well-known autoimmune conditions. There is a large body of evidence describing the clinical presentation of seizures with MS and SLE, and showing that refractory epilepsy can complicate these already challenging disorders. However, the mechanisms involved are complex and generally not well understood. Neurologic syndromes, including seizure disorders, can also be a feature of celiac disease (CD) or subclinical CD, sometimes associated with cerebral calcification. The association between type-1 diabetes mellitus (T1DM) and epilepsy is unclear and requires more definitive epidemiologic analysis, despite the fact that antibodies to glutamic acid decarboxylase may provide a link between the two conditions. The association between thyroid disorders and encephalopathies, often termed Hashimoto's encephalopathy, is well known but the pathogenic significance of antithyroid antibodies in this condition is still debated. In general, the relationships between autoimmune mechanisms and seizures in these conditions are unclear; the seizures are likely to be caused by a variety of mechanisms, including ischemia, neuronal damage, and specific and nonspecific immunity.

    Burkitt lymphoma presenting in the thyroid gland is rare, and only a few cases have been reported. We retrospectively reviewed 7 patients diagnosed with Burkitt lymphoma of the thyroid gland between 2000 and 2015. There were 4 men and 3 women with a median age of 41 years (range, 19-49 years). All patients presented with a rapidly growing neck mass associated with upper airway compression in 5 (71%) patients. Two patients presented with localized (stage I/II) and 5 patients with disseminated (stage III/IV) disease. All cases showed morphologic and immunophenotypic features of Burkitt lymphoma with MYC rearrangement in all 5 cases tested. One case showed evidence of concurrent Hashimoto thyroiditis. Six of 7 patients were treated primarily with rituximab, hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone. One patient was treated primarily with dose-adjusted rituximab, etoposide, prednisolone, vincristine, and cyclophosphamide. At the end of the study period, 5 patients were alive: 4 in complete remission and 1 with persistent disease. Two patients died with persistent disease (median follow-up, 25 months; range, 12-361 months). We conclude that Burkitt lymphoma of the thyroid gland shows clinicopathologic features similar to sporadic Burkitt lymphoma at other anatomic sites, but patients present at an older median age. The clinical course is aggressive with a high frequency of disseminated disease at diagnosis; however, a subset of patients responds well to aggressive chemotherapy.

    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

    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.

    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.

  1. Report of a case of papillary thyroid carcinoma in association with Hashimoto's thyroiditis

    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.

    Thyroid associated ophthalmopathy is an autoimmune disorder affecting the orbital and periorbital tissues. Hyperthyroidism is commonly associated with thyroid associated ophthalmopathy, however in 5% to 10% of cases it is euthyroid. Genetic, environmental and endogenous factors play a role in the initiation of the thyroid ophthalmopathy. Smoking has been identified as the strongest risk factor for the development of the disorder. The pathogenesis involves activation of both humoral and cell m...

    The focus of this article is on clinical ethics issues in the thyroid disease context. Clinical ethics is a subspecialty of bioethics that deals with bedside ethical dilemmas that specifically involve the provider-patient relationship. Such issues include consent and capacity; weighing therapeutic benefits against risks and side-effects; innovative therapies; end of life care; unintended versus intentional harms to patients or patient populations; and healthcare access. This article will review core ethical principles for practice, as well as the moral and legal requirements of informed consent. It will then discuss the range of unique and universal ethical issues and considerations that present in the management of autoimmune thyroid disease and thyroid cancer.

    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

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

    Directory of Open Access Journals (Sweden)

    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.

    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

  11. Deep vein thrombosis, an unreported first manifestation of polyglandular autoimmune syndrome type III

    Science.gov (United States)

    Hogan, P; Oliver, T

    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.

    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

    The multiple autoimmune syndromes (MAS) consist on the presence of three or more well-defined autoimmune diseases (ADs) in a single patient. The aim of this study was to analyze the clinical and genetic characteristics of a large series of patients with MAS. A cluster analysis and familial aggregation analysis of ADs was performed in 84 patients. A genome-wide microsatellite screen was performed in MAS families, and associated loci were investigated through the pedigree disequilibrium test. Systemic lupus erythematosus (SLE), autoimmune thyroid disease (AITD), and Sjögren's syndrome together were the most frequent ADs encountered. Three main clusters were established. Aggregation for type 1 diabetes, AITD, SLE, and all ADs as a trait was found. Eight loci associated with MAS were observed harboring autoimmunity genes. The MAS represent the best example of polyautoimmunity as well as the effect of a single genotype on diverse phenotypes. Its study provides important clues to elucidate the common mechanisms of ADs (i.e., autoimmune tautology).

    Balucan, Francis S.; Morshed, Syed A.; Davies, Terry F.

    2013-01-01

    Autoantibodies to thyroglobulin and thyroid peroxidase are common in the euthyroid population and are considered secondary responses and indicative of thyroid inflammation. By contrast, autoantibodies to the TSH receptor are unique to patients with Graves' disease and to some patients with Hashimoto's thyroiditis. Both types of thyroid antibodies are useful clinical markers of autoimmune thyroid disease and are profoundly influenced by the immune suppression of pregnancy and the resulting loss of such suppression in the postpartum period. Here, we review these three types of thyroid antibodies and their antigens and how they relate to pregnancy itself, obstetric and neonatal outcomes, and the postpartum. PMID:23691429

  1. Non-autoimmune subclinical hypothyroidism due to a mutation in TSH receptor: report on two brothers

    Directory of Open Access Journals (Sweden)

    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.

    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

  4. 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

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.

  7. 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

     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

    Vaccines have been used for over 200 years and are the most effective way of preventing the morbidity and mortality associated with infections. Like other drugs, vaccines can cause adverse events, but unlike conventional medicines, which are prescribed to people who are ill, vaccines are administered to healthy individuals, thus increasing the concern over adverse reactions. Most side effects attributed to vaccines are mild, acute and transient; however, rare reactions such as hypersensitivity, induction of infection, and autoimmunity do occur and can be severe and even fatal. The rarity and subacute presentation of post-vaccination autoimmune phenomena means that ascertaining causality between these events can be difficult. Moreover, the latency period between vaccination and autoimmunity ranges from days to years. In this article, on the basis of published evidence and our own experience, we discuss the various aspects of the causal and temporal interactions between vaccines and autoimmune phenomena, as well as the possible mechanisms by which different components of vaccines might induce autoimmunity.

    The complement system is a component of the innate immune system. Its main function was initially believed to be limited to the recognition and elimination of pathogens through direct killing or stimulation of phagocytosis. However, in recent years, the immunoregulatory functions of the complement system were demonstrated and it was determined that the complement proteins play an important role in modulating adaptive immunity and in bridging innate and adaptive responses. When the delicate mechanisms that regulate this sophisticated enzymatic system are unbalanced, the complement system may cause damage, mediating tissue inflammation. Dysregulation of the complement system has been involved in the pathogenesis and clinical manifestations of several autoimmune diseases, such as systemic lupus erythematosus, vasculitides, Sjögren's syndrome, antiphospholipid syndrome, systemic sclerosis, dermatomyositis, and rheumatoid arthritis. Complement deficiencies have been associated with an increased risk to develop autoimmune disorders. Because of its functions, the complement system is an attractive therapeutic target for a wide range of diseases. Up to date, several compounds interfering with the complement cascade have been studied in experimental models for autoimmune diseases. The main therapeutic strategies are inhibition of complement activation components, inhibition of complement receptors, and inhibition of membrane attack complex. At present, none of the available agents was proven to be both safe and effective for treatment of autoimmune diseases in humans. Nonetheless, data from preclinical studies and initial clinical trials suggest that the modulation of the complement system could constitute a viable strategy for the treatment of autoimmune conditions in the decades to come.

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.

    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.

  17. 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

    1989-07-01

    We studied ovarian function retrospectively in 66 women who had regular menstrual cycles before undergoing complete thyroidectomy for differentiated thyroid cancer and subsequent thyroid remnant ablation with /sup 131/I. Eighteen women developed temporary amenorrhea accompanied by increased serum gonadotropin concentrations during the first year after /sup 131/I therapy. No correlation was found between the radioactive iodine dose absorbed, thyroid uptake before treatment, oral contraceptive use, or thyroid autoimmunity. Only age was a determining factor, with the older women being the most affected. We conclude that radioiodine ablation therapy is followed by transient ovarian failure, especially in older women.

MATERIALS AND METHODS This is a prospective study, which consists of 150 patients aged more than 60 years and were admitted to Government General Hospital, Nizamabad. They were under suspicion that they were suffering from thyroid disorders and were subjected to detailed clinical examination as per proforma. Thyroid antibody test was done for those who were found to have altered thyroid functions. From these patients, demographic details, anthropometric measurements, and clinical information was collected. Serum T3, T4, and TSH levels were evaluated in the laboratory by chemiluminescence assay method. Other tests like USG/FNAC neck, CBC, RBS, Lipid profile, PS, ESR, ECG, Echo were done. INCLUSION CRITERIA 150 patients with age of above 60 years were selected who were suspected to have thyroid disorders. EXCLUSION CRITERIA Patients who were sick, who were with established thyroid disorders, who were using drugs, which alter thyroid functions, who were using thyroid supplements, who have undergone thyroid surgery, who have been on radioactive iodine therapy, who were using iodine-containing vitamins and minerals, who have undergone radiological tests. RESULTS In the present study, out of 150 patients, 82 males and 68 were females. It was found that the thyroid dysfunction is more among females (21% than in males (14%. This was seen in both hypothyroidism and hyperthyroidism as females have increased autoimmune diseases. Out of 150 patients, only 35% had total thyroid abnormalities.

    Glycogen storage disease type 1b (GSD1b) is an inherited metabolic defect of glycogenolysis and gluconeogenesis due to mutations of the SLC37A4 gene and to defective transport of glucose-6-phosphate. The clinical presentation of GSD1b is characterized by hepatomegaly, failure to thrive, fasting hypoglycemia, and dyslipidemia. Patients affected by GSD1b also show neutropenia and/or neutrophil dysfunction that cause increased susceptibility to recurrent bacterial infections. GSD1b patients are also at risk for inflammatory bowel disease. Occasional reports suggesting an increased risk of autoimmune disorders in GSD1b patients, have been published. These complications affect the clinical outcome of the patients. Here we describe the occurrence of autoimmune endocrine disorders including thyroiditis and growth hormone deficiency, in a patient affected by GSD1b. This case further supports the association between GSD1b and autoimmune diseases.

    Full Text Available Autoimmunity and viral infections are closely associated fields, and viruses have been proposed as a likely aetiological, contributory or triggering factors of systemic autoimmune diseases. Hepatitis C virus seems to be the virus usually associated with the appearance of autoimmune diseases, and the relationship between chronic hepatitis C virus infection and some autoimmune disease has been studied. For some of these disorders their association with hepatitis C virus infection is well recognized while for others it remains probable or weak. Examples of autoimmune phenomena observed in chronic hepatitis C virus infection include rheumatoid arthritis, thyroid disease, cryoglobulinaemia, immune thrombocytopenic purpura, systemic lupus erythematosus and sjogren syndrome. To date, the etiological role and the pathogenetic involvement of the hepatitis C infection remains unknown.The aim of this study is to assess the presence of different autoimmune manifestations of hepatitis C virus infection reported in literature.

    There is increasing recognition of an autoimmune origin of pharmacoresistant epileptic disorders. Besides the paraneoplastic limbic encephalopathies (LE), reports of syndromes of non-paraneoplastic LE are increasingly reported in the last 5-10 years. Three antibodies are now relatively well described: Voltage-gated potassium channels (VGKC), glutamic acid decarboxylase (GAD) and N-methyl-D-aspartate receptor-(NMDA) antibodies. We review clinical syndromes, associated imaging and laboratory findings. While most reports arise from adult populations, children and adolescents are also concerned as evidenced by increasing observations. Early recognition is mandatory, since early immunomodulatory treatment appears to be related to significantly better outcome. PMID:20499581

    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

    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 this condition is a distinct entity or a form of

    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 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 Introduction: Previous research on autoimmune skin blistering diseases (ABD has primarily focused on the humoral immune response; moreover, little attention has been given to the potential role of the antigen presenting cells (APCs in lesional skin. 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

    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

    Full Text Available Background: Approximately 2-4% of all women have recurrent spontaneous abortion (RSA; however, the cause is determined in only 50% of cases. Recent studies have shown an association between thyroid autoantibodies as a sign of thyroid autoimmunity and abortion. The aim of the present study was to determine whether circulating anti-thyroid peroxidase (anti-TPO was associated with RSA.Materials and Methods: In this observational analytic study, Sera from 58 non-pregnant women with a history of RSA and also 58 healthy, fertile subjects with at least one live birth as control (Aging from 18 to 45 years were tested for thyroid peroxidase antibodies by means of a standard Anti-TPO ELISA kit. We used data collection forms and SPSS software for data analysis.Results: Of 116 women, 8 (13.8% of the control subjects and 12 (20.7% of the women with a history of RSA had positive results for anti-TPO. There was not any significant association between presence of anti-TPO and RSA.Conclusions: We did not find any correlation between the presence of TPO antibodies and abortion in women with a history of RSA. On the basis of this study, testing for anti-TPO doesn’t seem to be useful in the evaluation of patients with a history of RSA.

    The last few years have witnessed numerous publications addressing the management of thyroid nodules and differentiated thyroid cancers. The purpose of this review is to provide a simplified summary of the newly released guidelines by the American Thyroid Association. A systematic approach has been recommended to evaluate a thyroid nodule through clinical assessment, measurement of serum Thyroid Stimulating Hormone, neck ultrasonography and Fine Needle Aspiration where appropriate. This is followed by cytology analysis using the Bethesda scoring system to detect malignancy. Once diagnosed, thyroid cancers need to be staged and risk stratification needs to be applied to develop further treatment plans. Lastly, several recommendations have been presented to assure proper follow-up and support for thyroid cancer patients regardless of the treatment received. PMID:27607088

    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.

    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.

  13. 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

    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.

    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.

    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)

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 Bardet-Biedel syndrome (BBS is a rare autosomal recessive, genetically heterogeneous ciliopathy. Although the disease has been described in a patient with psoriasis, individuals with BBS are not known to be at risk of developing autoimmune disorders. Our objective was to describe a 14-year-old patient with BBS who presented with Crohn disease (CD, primary sclerosing cholangitis (PSC, and thyroiditis in the context of a cohort review at Sainte-Justine Hospital and to alert clinicians to the increased risk of autoimmune disorders in these patients. The cohort contained fifteen patients (9 boys, followed from 1968 to 2009 during a median period of 12 years (range 9 months–26 years. Three of the 15 patients (20% developed a chronic autoimmune disease: one had juvenile rheumatoid arthritis; a second one had type 1 diabetes mellitus in association with Hashimoto thyroiditis and psoriasis; a third one developed CD, PSC, and Hashimoto thyroiditis. As chronic autoimmune diseases occurred in 20% of our cohort of children with BBS, it is appropriate to keep this association in mind during the followup.

  20. 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

    Dual ectopic lingual and sublingual thyroid gland is an extraordinarily rare condition. We present 1 patient with subclinical hypothyroidism. The clinical examination revealed that the thyroid gland was not palpable in its usual cervical location, whereas ultrasonography confirmed an empty thyroid bed without any ectopic thyroid tissue in the rest of the neck. The final diagnosis of dual ectopic lingual and sublingual thyroid was established by ultrasound examination through the mouth floor and confirmed by scintigraphy and CT thereafter.

    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.

    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.

    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.

    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.

    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.

    Hashimoto's thyroiditis (HT) is part of a spectrum of thyroid autoimmune conditions and this review provides an update on the latest developments in the field. HT has a genetic predisposition with a number of immune-related and thyroid-specific genes conferring disease susceptibility. However, disentangling genes with protective and predisposing effect is a complex process that requires further work. The recent increase in the incidence of HT implicates environmental factors in disease pathogenesis including improved hygiene, increased dietary iodine intake, new treatment modalities and chemical agents. Additional unmodifiable predisposing factors include stress, climate, age and gender. Both cellular and humoral immunity play a role in HT pathogenesis. Defects in T regulatory cells and increased activation of follicular helper T cells may have a role in disease initiation/perpetuation. Infiltrating lymphocytes can be directly cytotoxic to thyroid follicular cells (TFC) or may affect cell viability/function indirectly through cytokine production, which alters TFC integrity and modulates their metabolic and immune function. Thyroid peroxidase and thyroglobulin antibodies are present in the majority of HT patients and help with management decisions. Antibodies against the sodium iodide symporter and pendrin are present in a minority with little known about their clinical relevance. In addition to immune cells, recent work has identified DNA fragments, generated following cell death, and micro RNA as potential factors in HT pathogenesis. Despite the large number of studies, the mechanistic pathways in HT are still not fully understood and further work is required to enhance our knowledge and identify novel preventative and therapeutic clinical targets.

    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.

Especially the one-year postpartum period was associated with an increased risk of Hashimoto thyroiditis, Graves' disease and sarcoidosis. Overall, parity was...... associated with an 11% increased risk of female predominant autoimmune diseases. Pregnancies resulting in liveborn children therefore seem to contribute only little to the general female predominance in autoimmune diseases. However, for a number of autoimmune diseases; especially autoimmune thyroid diseases...

    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 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.

  14. Possible Role of Human Herpesvirus 6 as a Trigger of Autoimmune Disease

    2013-01-01

    Full Text Available Human herpesvirus 6 (HHV-6 infection is common and has a worldwide distribution. Recently, HHV-6A and HHV-6B have been reclassified into two distinct species based on different biological features (genetic, antigenic, and cell tropism and disease associations. A role for HHV-6A/B has been proposed in several autoimmune disorders (AD, including multiple sclerosis (MS, autoimmune connective tissue diseases, and Hashimoto's thyroiditis. The focus of this review is to discuss the above-mentioned AD associated with HHV-6 and the mechanisms proposed for HHV-6A/B-induced autoimmunity. HHV-6A/B could trigger autoimmunity by exposing high amounts of normally sequestered cell antigens, through lysis of infected cells. Another potential trigger is represented by molecular mimicry, with the synthesis of viral proteins that resemble cellular molecules, as a mechanism of immune escape. The virus could also induce aberrant expression of histocompatibility molecules thereby promoting the presentation of autoantigens. CD46-HHV-6A/B interaction is a new attractive mechanism proposed: HHV-6A/B (especially HHV-6A could participate in neuroinflammation in the context of MS by promoting inflammatory processes through CD46 binding. Although HHV-6A/B has the ability to trigger all the above-mentioned mechanisms, more studies are required to fully elucidate the possible role of HHV-6A/B as a trigger of AD.

    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.

    Thyroid pathology including thyroid nodules and diffuse thyroid diseases represents often a diagnosing challenge for clinicians. 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.

    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.

    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 that the pathologic mechanisms may be similar among autoimmune diseases. Lastly, genetic evidence shows that autoimmune phenotypes might represent pleiotropic outcomes of the interaction of non-specific disease genes.

    Full Text Available Autoimmunity is characterized by the reaction of cells (auto reactive T-lymphocytes or products (autoantibodies of the immune system against the organism’s own antigens (autoantigen. 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.

    Full Text Available 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.

    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

    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

    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.

    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

  15. 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

    Full Text Available Alcohol is one of the commonest illicit psychoactive substances consumed globally and is the world′s third largest risk factor for disease and disability. It has been reported to have multiple effects on the hypothalamo-pituitary-thyroid axis and the functioning of the thyroid gland. It has been reported to cause direct suppression of thyroid function by cellular toxicity, and indirect suppression by blunting thyrotropin-releasing hormone response. It causes a decrease of peripheral thyroid hormones during chronic use and in withdrawal. Alcohol use may also confer some protective effect against thyroid nodularity, goiter, and thyroid cancer. This article presents a review of the clinically relevant effects of alcohol on the functioning of the thyroid gland and also discusses the effect of medication used in treatment of alcohol dependence on thyroid function.

    Full Text Available BACKGROUND A healthy and well-functioning thyroid gland is important to everyone, but it is especially important to a woman in their child bearing age. Postpartum thyroiditis is a syndrome of transient or permanent thyroid dysfunction occurring in the first year after delivery and based on autoimmune inflammation of thyroid gland. (1,2 AIMS AND OBJECTIVES 1. To determine the prevalence of thyroid dysfunction in postpartum period. 2. To see the prevalence of TPOab in the postpartum thyroiditis. 3. Percentage of recovery normal thyroid function after postpartum period. MATERIAL AND METHOD This study was carried out in the Department of Medicine and Obstetrics and Gynaecology Department of L.L.R.M Medical College, Meerut, from May 2013 to May 2014; 100 women of postpartum period was selected from OPD and Wards and subjected to a protocol which include history specially palpitation, depression, fatigue, sweating, constipation and examination with a special reference to general body built, height, weight, pulse, BP, respiratory rate, pallor, cyanosis, icterus, oedema, lymphadenopathy, body temperature, eyes signs, hairs and skin changes and BMR were noted. All the system were examined thoroughly. Thyroid gland was examined thoroughly. All the women are subjected to following investigation.

    Seventy-nine patients with chronic lymphocytic leukaemia were evaluated for the presence of autoimmune diseases and autoantibodies. One patient has polymyositis and two additional patients presented with features suggestive of pernicious anaemia and chronic active hepatitis. The Coombs' direct test was positive in 7% and immune thrombocytopenia was present in 8.1% of patients. Five (7%) patients had M-protein in the serum. No increased frequency of other autoantibodies was noted in our study group. We conclude that the propensity to develop antibodies is restricted only to the haematopoietic system and that there is no increased frequency of non-haematological autoimmune diseases in chronic lymphatic leukaemia.

    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.

    Full Text Available Similar pathophysiological mechanisms within autoimmune diseases have stimulated searches for common genetic roots. Polyautoimmunity is defined as the presence of more than one autoimmune disease in a single patient. When three or more autoimmune diseases coexist, this condition is called multiple autoimmune syndrome (MAS. We analyzed the presence of polyautoimmunity in 1,083 patients belonging to four autoimmune disease cohorts. Polyautoimmunity was observed in 373 patients (34.4%. Autoimmune thyroid disease (AITD and Sjögren's syndrome (SS were the most frequent diseases encountered. Factors significantly associated with polyautoimmunity were female gender and familial autoimmunity. Through a systematic literature review, an updated search was done for all MAS cases (January 2006–September 2011. There were 142 articles retrieved corresponding to 226 cases. Next, we performed a clustering analysis in which AITD followed by systemic lupus erythematosus and SS were the most hierarchical diseases encountered. Our results indicate that coexistence of autoimmune diseases is not uncommon and follows a grouping pattern. Polyautoimmunity is the term proposed for this association of disorders, which encompasses the concept of a common origin for these diseases.

    Resistance to thyroid hormone is an uncommon problem, which has rarely been associated with thyroid dysgenesis. We report a case with both thyroid gland ectopy and resistance to thyroid hormone and, thus, a reduced capacity to produce and respond to thyroid hormone. The patient presented at 2 years of age with developmental delay, dysmorphic features, and elevation in both thyroxine and thyrotropin. We document her response to therapy with thyroxine, with particular regard to her growth and development. Persistent elevation of thyrotropin is commonly recognized during treatment of congenital hypothyroidism. Resistance to thyroid hormone may be an important additional diagnosis to consider in cases where thyrotropin remains persistently elevated.

    Full Text Available Thyroid diseases, especially hypothyroidism, are among the most frequent endocrine complications in patients with Hodgkin lymphoma whohave received neck irradiation. Thyroid function was evaluated in 34 patients (11 males and 23 females after combined chemo radiotherapyof Hodgkin lymphoma according to modified DAL-HD-90M and GPOH-HD-2002 protocols. The median age was 15.9 years (range 5–18 years, the median time from the end of therapy was 1.08 years (range 1 month–4.9 years. 33 patients received radiotherapy to the neck region: 12 children — 20 Gy, 9 — 25 Gy, 10 — 30 Gy, 2 — 35 Gy. These patients were investigated by clinical examination, thyroid ultrasound and thyroid function tests. Thyroid abnormalities were detected in 4 of 21 patients who received 20–25 Gy (1 case of autoimmune thyroiditis and 3 cases of subclinical hypothyroidism and in 3 of 12 patients who received 30–35 Gy (2 cases of autoimmune thyroiditis and 1 case of subclinical hypothyroidism. Autoimmune thyroiditis also developed in patient who received only 35 Gy mediastinum irradiation. Age, sex, follow-up time, irradiation dose were not significant factors in the thyroid dysfunction development. Thyroid examination must be obligatory part of the follow-up examination of patients with Hodgkin lymphoma.

  6. DNA Methylation in Thyroid Tumorigenesis

    International Nuclear Information System (INIS)

    Thyroid cancer is the most common endocrine cancer with 1,690 deaths each year. There are four main types of which the papillary and follicular types together account for >90% followed by medullary cancers with 3% to 5% and anaplastic carcinomas making up <3%. Epigenetic events of DNA hypermethylation are emerging as promising molecular targets for cancer detection. Our immediate and long term goal is to identify DNA methylation markers for early detection of thyroid cancer. This pilot study comprised of 21 patients to include 11 papillary thyroid cancers (PTC), 2 follicular thyroid cancers (FTC), 5 normal thyroid cases, and 3 hyperthyroid cases. Aberrant promoter methylation was examined in 24 tumor suppressor genes using the methylation specific multiplex ligation-dependent probe amplification (MS-MLPA) assay and in the NIS gene using methylation-specific PCR (MSP). The frequently methylated genes were CASP8 (17/21), RASSF1 (16/21) and NIS (9/21). In the normal samples, CASP8, RASSF1 and NIS were methylated in 5/5, 4/5 and 1/5 respectively. In the hyperthyroid samples, CASP8, RASSF1 and NIS were methylated in 3/3, 2/3 and 1/3 respectively. In the thyroid cancers, CASP8, RASSF1, and NIS were methylated in 9/13, 10/13, and 7/13 respectively. CASP8, RASSF1 and NIS were also methylated in concurrently present normal thyroid tissue in 3/11, 4/11 and 3/11 matched thyroid cancer cases (matched for presence of both normal thyroid tissue and thyroid cancer), respectively. Our data suggests that aberrant methylation of CASP8, RASSF1, and NIS maybe an early change in thyroid tumorigenesis regardless of cell type

  7. The thyroid, iodine and breast cancer

    International Nuclear Information System (INIS)

    A renewal of the search for a link between breast cancer and thyroid disease has once again demonstrated an increased prevalence of autoimmune thyroid disease in patients with breast cancer. This is the most recent of many studies showing an association between a variety of thyroid disorders and breast cancer. Such an association is not surprising as both diseases are female predominant with a similar postmenopausal peak incidence. The significance of the presence of thyroid autoantibodies, particularly thyroid peroxidase antibodies, in serum from patients with breast cancer is unknown, but it has been suggested that antibody positivity is associated with better prognosis. One area in which thyroid and breast functions overlap is in the uptake and utilization of dietary iodide. Experimental findings showing the ability of iodine or iodine-rich seaweed to inhibit breast tumour development is supported by the relatively low rate of breast cancer in Japanese women who consume a diet containing iodine-rich seaweed. However, there is as yet no direct evidence that iodine, iodinated compounds, or a combination of iodine and selenium is the antimammary carcinogenic element in the Japanese diet. It remains to be resolved whether the perceived breast cancer–thyroid disease relationship is thyroid or iodine related or, in the case of thyroid autoantibodies, is the consequence of an immune response to the carcinoma. Is this response breast specific and does it relate to iodine status? These and many other questions await resolution before a definitive role in the natural history of breast carcinoma can be assigned to the thyroid

    2016-01-01

    In recent years a large number of antibody-associated or antibody-defined encephalitides have been discovered. These conditions are often referred to as autoimmune encephalitides. The clinical features include prominent epileptic seizures, cognitive and psychiatric disturbance. These encephalitides can be divided in those with antibodies against intracellular antigens and those with antibodies against surface antigens. The discovery of new antibodies against targets on the surface of neurons is especially interesting since patients with such antibodies can be successfully treated immunologically. This chapter focuses on the pathology and the pathogenetic mechanisms involved in these encephalitides and discusses some of the questions that are raised in this exciting new field. It is important to realise, however, that because of the use of antibodies to diagnose the patients, and their improvement with treatment, there are relatively few biopsy or postmortem reports, limiting the neuropathological data and conclusions that can be drawn. For this reason we especially focus on the most frequent autoimmune encephalitides, those with antibodies to the NMDA receptor and with antibodies to the known protein components of the VGKC complex. Analysis of these encephalitides show completely different pathogenic mechanisms. In VGKC complex encephalitis, antibodies seem to bind to their target and activate complement, leading to destruction and loss of neurons. On the other hand, in NMDAR encephalitis, complement activation and neuronal degeneration seems to be largely absent. Instead, binding of antibodies leads to a decrease of NMDA receptors resulting in a hypofunction. This hypofunction offers an explanation for some of the clinical features such as psychosis and episodic memory impairment, but not for the frequent seizures. Thus, additional analysis of the few human brain specimens present and the use of specific animal models are needed to further understand the effects

    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

    Thyroid nodules are a common manifestation of thyroid diseases. It is estimated that approximately 10% of adults have palpable thyroid nodules with the frequency increasing throughout life. The major concern on nodule evaluation is the risk of malignancy (5-10%). Differentiated thyroid carcinoma accounts for 90% of all thyroid malignant neoplasias. Although most patients with cancer have a favorable outcome, some individuals present an aggressive form of the disease and poor prognostic despite recent advances in diagnosis and treatment. Here, a set of clinical guidelines for the evaluation and management of patients with thyroid nodules or differentiated thyroid cancer was developed through consensus by 8 member of the Department of Thyroid, Sociedade Brasileira de Endocrinologia e Metabologia. The participants are from different reference medical centers within Brazil, to reflect different practice patterns. Each committee participant was initially assigned to write a section of the document and to submit it to the chairperson, who revised and assembled the sections into a complete draft document, which was then circulated among all committee members for further revision. All committee members further revised and refined the document. The guidelines were developed based on the expert opinion of the committee participants, as well as on previously published information.

    There is genetic evidence of similarities and differences among autoimmune diseases (AIDs) that warrants looking at a general panorama of what has been published. Thus, our aim was to determine the main shared genes and to what extent they contribute to building clusters of AIDs. We combined a text-mining approach to build clusters of genetic concept profiles (GCPs) from the literature in MedLine with knowledge of protein-protein interactions to confirm if genes in GCP encode proteins that truly interact. We found three clusters in which the genes with the highest contribution encoded proteins that showed strong and specific interactions. After projecting the AIDs on a plane, two clusters could be discerned: Sjögren's syndrome-systemic lupus erythematosus, and autoimmune thyroid disease-type1 diabetes-rheumatoid arthritis. Our results support the common origin of AIDs and the role of genes involved in apoptosis such as CTLA4, FASLG, and IL10.

    Thyroid disease is common in younger women and may be a factor in reproductive dysfunction. This probably only applies to severe cases of hyper- or hypothyroidism. Once adequately treated, neither of these disorders significantly impacts on fertility. The key is to recognize and to treat thyroid disorders in the reproductive-age woman before conception. Thyroxine therapy and even antithyroid drug therapy should be continued during pregnancy as necessary. Pregnancy is a euthyroid state that is normally maintained by complex changes in thyroid physiology. The fetal and neonatal hypothalamic-pituitary-thyroid system develops independently, but it may be influenced by thyroid disease in the mother. Early pregnancy is characterized by an increase in maternal T4 secretion stimulated by hCG and an increase in TBG, resulting in the elevated total serum T4 in pregnancy. The debate continues as to whether maternal T4 is important in early or late fetal brain development. If so, the physiologic changes in thyroid hormone secretion and transport in early pregnancy would help to ensure that a sufficient amount of thyroid hormone was available. There is new evidence in human subjects that substantial maternal T4 can cross the placenta during pregnancy, and this may be particularly important when fetal thyroid function is compromised as a result of congenital hypothyroidism. Maternal and fetal/neonatal outcomes in pregnancy are adversely affected if severe hypothyroidism is undiagnosed or inadequately treated. Thyroid function tests should be obtained during gestation in women taking T4 and appropriate dose adjustments should be made for TSH levels outside a normal range. The TSH-receptor blocking antibodies from the mother are a recognized cause of congenital hypothyroidism in the fetus and neonate that can be permanent or transient. If neonatal hypothyroidism is detected through neonatal screening programs, and prompt and adequate T4 replacement therapy is instituted as soon as

    One hundred and ninety-one people who reside in radiation-contaminated areas of the Ukraine near the site of the Chernobyl nuclear plant accident were screened in 1999. The ages of people screened ranged from 1 to 74 years. Diffuse goiter was palpable in 67.5%, and nodular goiter in 3.1%. Thyroid cancer was detected in only one suspicious case. Among the people with diffuse goiter, however, there were positive anti-thyroglobulin hemagglutination tests (TGHA) in 6.7% and positive anti-microsome hemagglutination tests (MCHA) in 16.7% of cases. In addition, urinary iodine concentrations and daily urinary excretion were low. Thus, it is thought that the majority of diffuse goiters in this area are not due to autoimmune thyroiditis but to iodine deficiency. At present, no definite conclusion can be drawn on the relationship between the large number of diffuse goiters and radioactive contamination. Further studies are required. (author)

    Full Text Available Objective: The objectives were to evaluate fine needle aspiration cytology results of 39 pediatric patients, and the pathologies that cause childhood thyroid nodules, and to review the literature on the subject.Material and Method: Thyroid fine needle aspiration cytology results of 39 pediatric patients were retrospectively reviewed. Associated diseases, thyroid functions, anti-thyroid antibody levels, ultrasonographic findings and number of nodules were also evaluated.Results: The vast majority of patients with thyroid nodules were cytopathologically diagnosed as benign (97.3%. Of these patients, 64.8% (24 patients were diagnosed as nodular goiter and 35.2% (13 patients as lymphocytic thyroiditis. Thyroid malignancy was found in two patients; one was diagnosed as follicular neoplasm/ minimal invasive follicular carcinoma on surgical evaluation while the other was a secondary tumor (Burkitt's lymphoma. The majority of our subjects were females (66.6%: the female/male ratio was 2:1 for nodular goiter and 3.3:1 for thyroiditis. Surgical resection was performed in 5 patients (4 cases of nodular goiter, 1 suspicious for malignancy and cytological diagnoses were confirmed by histology.Conclusion: Our study confirmed the utility of fine needle aspiration cytology in childhood thyroid disorders along with a possible higher incidence of nodular thyroiditis in childhood. Nodular autoimmune thyroiditis, focal thyroiditis and thyroid cancer in children are discussed and attention is drawn to some special subtypes of thyroid cancer and some benign lesions that can cause difficulty in interpreting fine needle aspiration cytology and frozen sections at this age.

    Autoimmune thyroid diseases (AITD) are common, affecting 2-5% of the general population. Individuals with positive thyroid peroxidase antibodies (TPOAbs) have an increased risk of autoimmune hypothyroidism (Hashimoto's thyroiditis), as well as autoimmune hyperthyroidism (Graves' disease). As the possible causative genes of TPOAbs and AITD remain largely unknown, we performed GWAS meta-analyses in 18,297 individuals for TPOAb-positivity (1769 TPOAb-positives and 16,528 TPOAb-negatives) and in 12,353 individuals for TPOAb serum levels, with replication in 8,990 individuals. Significant associations (P<5×10(-8)) were detected at TPO-rs11675434, ATXN2-rs653178, and BACH2-rs10944479 for TPOAb-positivity, and at TPO-rs11675434, MAGI3-rs1230666, and KALRN-rs2010099 for TPOAb levels. Individual and combined effects (genetic risk scores) of these variants on (subclinical) hypo- and hyperthyroidism, goiter and thyroid cancer were studied. Individuals with a high genetic risk score had, besides an increased risk of TPOAb-positivity (OR: 2.18, 95% CI 1.68-2.81, P = 8.1×10(-8)), a higher risk of increased thyroid-stimulating hormone levels (OR: 1.51, 95% CI 1.26-1.82, P = 2.9×10(-6)), as well as a decreased risk of goiter (OR: 0.77, 95% CI 0.66-0.89, P = 6.5×10(-4)). The MAGI3 and BACH2 variants were associated with an increased risk of hyperthyroidism, which was replicated in an independent cohort of patients with Graves' disease (OR: 1.37, 95% CI 1.22-1.54, P = 1.2×10(-7) and OR: 1.25, 95% CI 1.12-1.39, P = 6.2×10(-5)). The MAGI3 variant was also associated with an increased risk of hypothyroidism (OR: 1.57, 95% CI 1.18-2.10, P = 1.9×10(-3)). This first GWAS meta-analysis for TPOAbs identified five newly associated loci, three of which were also associated with clinical thyroid disease. With these markers we identified a large subgroup in the general population with a substantially increased risk of TPOAbs. The results provide insight into why

    The histological hallmark of autoimmune hepatitis (AIH) is a dense portal mononuclear cell infiltrate that invades the surrounding parenchyma and comprises T and B lymphocytes,macrophages,and plasma cells.An unknown but powerful stimulus must be promoting the formation of this massive inflammatory cellular reaction that is likely to initiate and perpetuate liver damage.An autoimmune attack can follow different pathways to inflict damage on hepatocytes.Liver damage is likely to be orchestrated by CD4+T lymphocytes recognizing an autoantigenic liver peptide.To trigger an autoimmune response,the peptide must be embraced by an HLA class Ⅱ molecule and presented to naive CD4+T helper (Th0) cells by professional antigen presenting cells,with the co-stimulation of ligand-ligand fostering interaction between the two cells.Th0 cells become activated,differentiate into functional phenotypes according to the cytokines prevailing in the microenvironment and the nature of the antigen,and initiate a cascade of immune reactions determined by the cytokines produced by the activated T cells.Th1 cells,arising in the presence of the macrophage-derived interleukin (IL)-12,secrete mainly IL-2 and interferon-gamma (IFN-γ),which activate macrophages,enhance expression of HLA class Ⅰ (increasing liver cell vulnerability to a CD8+T cell cytotoxic attack),and induce expression of HLA class Ⅱ molecules on hepatocytes.Th2 cells,which differentiate from Th0 if the microenvironment is rich in IL-4,produce mainly IL-4,IL-10,and IL-13 which favour autoantibody production by B lymphocytes.Physiologically,Th1 and Th2 antagonize each other.Th17 cells,a recently described population,arise in the presence of transforming growth factor beta (TGF-β) and IL-6 and appear to have an important effector role in inflammation and autoimmunity.The process of autoantigen recognition is strictly controlled by regulatory mechanisms,such as those exerted by CD4+CD25+regulatory T cells,which derive from Th0

    Patients with thyroid nodules must be treated selectively because these nodules develop far more frequently than does thyroid cancer. A thorough clinical history, family history and history of radiation, as well as an accurate physical examination, are very important in determining whether surgical treatment is indicated. Thyroid function tests, a radioactive isotope scan, a thyroid echogram and fine-needle biopsy are also useful.

    Medical historians identify the mid-20th century as the time when the scientific and medical communities acknowledged the existence of autoimmune disease. Several conditions including sympathetic ophthalmia and endophthalmitis phacoanaphylactica, however, were proposed as autoimmune disorders much earlier. During the first half of the century, autoimmune disease was viewed as biologically implausible. Paul Ehrlich coined the term horror autotoxicus to emphasize that autoimmunity would contradict nature's aversion to self-injury. The discoveries of allergy and anaphylaxis were the first clues that the immune system was capable of self-harm. A major obstacle to comprehending the pathogenesis of autoimmunity was how the immune system distinguishes foreign from self, a process eventually understood in the context of immune tolerance. Investigators of sympathetic ophthalmia and endophthalmitis phacoanaphylactica were positioned to invalidate horror autotoxicus but lacked sufficiently convincing experimental and clinical evidence to accomplish the task. Seminal studies of chronic thyroiditis and a series of clinical laboratory breakthroughs led to the general acceptance of autoimmune disease in the 1950s. The travails encountered by ophthalmic investigators offer insights into the how medical ideas take shape. We review the contributions of ocular immunology to the conceptual development of autoimmune disease and explore the reasons why the concept caught on slowly. PMID:27131478

    Thyrotropin, free triodothyronine and thyroxine represent the standard serological parameters for the diagnostic work-up of the thyroid but only a minority of thyroid nodules present with subclinical or overt thyroid disorders. Besides a review of the regulation and principle of function of thyroid hormones as well as the effects of subclinical or overt hyperthyroidism, the significant role of these parameters beyond the assessment of hyperthyroidism in thyroid nodules is discussed. There is evidence that the level of thyrotropin within the normal range is predictive for the relevance of autonomous functioning nodules and the risk of malignancy of non-functioning thyroid nodules. Furthermore, the ratio of triodothyronine and thyroxine indicates the etiology of hyperthyroidism. Thyrotropin represents the main parameter to determine the adequate dose of thyroid hormone therapy of thyroid nodules. (orig.)

    We encountered a patient who presented with neck swelling, difficulty in swallowing, voice change along with systemic features such as evening rise of temperature, chronic cough and weight loss. Ultrasonography of the thyroid gland revealed two cystic swellings. An ultrasound guided fine needle aspiration cytology was suggestive of tubercular abscess. The patient responded well to antigravity aspiration of the swellings and antitubercular treatment.

  10. Imaging diagnosis of thyroid gland congenital anomalies

    International Nuclear Information System (INIS)

    The clinical and radiological findings in 25 patients presenting diverse thyroid gland anomalies are described, as follows: thyroid aplasia - 2, thyroid hemiagenesis - 9, lingual thyroid gland - 3, median cervical cysts - 8, lateral cervical aberrant tissue - 2, distant aberrant thyroid tissue - 1 case. In all patients the following methods are applied: echography, computer tomography and radionuclide examination with 99mTc. Conclusions are made that: 1) To make definite diagnosis of thyroid ectopia the complex application of imaging methods is mandatory. 2) Ultrasound examination is sufficient to establish agenesis, hypo- or hemiaplasia of the thyroidea without need to resort to other imaging modalities. 3) Ectopic thyroid tissue eventually discovered should be carefully monitored by echography and cytologically because of susceptibility of malignant degeneration

    International Nuclear Information System (INIS)

    In order to determine whether acute administration of iodide leads to any undesirable effects in the general population, we studied a group of patients who received iodinated radiographic contrast medium in the course of routine x-ray diagnostic procedures. We were particularly interested in investigating the possibility that administration of iodine could damage thyroid follicular cells leading to release of intrathyroidal antigens such as thyroglobulin into the blood. An increase in serum thyroglobulin might, in turn, either initiate or exacerbate thyroid autoimmunity in susceptible individuals, leading to autoimmune thyroiditis. We looked for undesirable effects due to the administration of iodide in 3 ways: a possible acute toxic effect on thyroid follicular cells was investigated by determining serum thyroglobulin immediately prior to and 24 hours after injection of iodinated contrast medium; an effect on thyroid autoimmunity was investigated by determining thyroid autoantibodies immediately prior to and 3 to 6 months after injection of iodinated contrast medium; and acute and chronic effects on thyroid function were investigated by performing thyroid function tests immediately prior to, 24 hours after and 3 to 6 months after injection of iodinateed contrast medium

    2005-01-01

    Full Text Available Secondary neoplasm of the thyroid mimicking a primary thyroid lesion is a rare finding, especially in an individual without a past history of malignancy. A case of squamous cell carcinoma metastatic to the thyroid (presenting as a solitary thyroid nodule, who had an unsuspected primary in the esophagus is described. Usually, multiple areas of the gland are involved in the secondary involvement of the thyroid. The clinical presentation of an apparently asymptomatic mass with neck lymphadenopathy, normal thyroid functions, and a cold nodule on 99mTcO4- thyroid scan can often lead to a misdiagnosis as primary thyroid neoplasm. The present case underscores the fact that due importance to the subtle signs and symptoms and a high degree of suspicion, whenever the histology is unusual for a thyroid primary, is needed and the workup should include ruling out other primary malignancies.

    Aims/hypothesis The discordance status of (autoimmune) type 1 diabetes within monozygotic twin pairs points to the importance of environmental factors. The aim of this study was to investigate whether the environmental events causing type 1 diabetes influence thyroid autoimmunity. Methods Monozygotic and dizygotic twins discordant for type 1 diabetes from the UK and USA were tested for thyroid peroxidase autoantibodies (TPOA) by radioimmunoassay. Using quantitative genetic model fitting of a liability-threshold model we estimated the contribution of genetic (heritability) and environmental factors to TPOA. Results TPOA positivity was higher in females than in males in both cohorts and was associated with later age at diagnosis in the UK and combined cohorts (p0.2 in all groups). The best-fitting models showed heritability (95% CI) estimates for TPOA of 63% (37%, 80%) for the UK and 80% (51%, 92%) for US twins, while the best-fitting meta-analysis model of the two twin cohorts combined included additive genetic and unique environmental factors with a heritability estimate of 69% (50%, 82%). Conclusions/interpretation Risk of thyroid autoimmunity, defined by TPOA, in the context of autoimmune diabetes is, substantially, genetically determined in discordant twin pairs. Environmental factors leading to type 1 diabetes were not the same as those involved with thyroid autoimmunity. It follows that it is as important to investigate for thyroid autoimmunity in relatives of type 1 diabetes patients as it is in the patients themselves. PMID:26070305

    Full Text Available Aims: The aim was to highlight recent advances in the treatment of thyroid eye disease. Settings and Design: Review article. Materials and Methods: Existing literature and the authors′ experience was reviewed. Results: Thyroid ophthalmopathy is a disfiguring and vision-threatening complication of autoimmune thyroid disease that may develop or persist even in the setting of well-controlled systemic thyroid status. Treatment response can be difficult to predict, and optimized algorithms for disease management do not exist. Thyroid ophthalmopathy should be graded for both severity and disease activity before choosing a treatment modality for each patient. The severity of the disease may not correlate directly with the activity; medical treatment is most effective in active disease, and surgery is usually reserved for quiescent disease with persistent proptosis and/or eyelid changes. Conclusions: Intravenous pulsed corticosteroids, orbital radiotherapy, and orbital surgical techniques form the mainstay of current management of thyroid ophthalmopathy. Immunosuppressive and biologic agents may have a role in treating active disease although additional safety and efficacy studies are needed.

    Full Text Available Background. Ultrasound (US is the most accurate tool in the diagnosis of thyroid nodules if performed by expert physician. Misdiagnosis due to extrathyroidal lesions mimicking thyroid nodules is reported in literature. We describe the first case of an esophageal fibrovascular polyp misdiagnosed as a thyroid nodule on US examination. Patient Findings. A 54-year-old woman presented to emergency department for headache and underwent carotid Doppler extended to neck ultrasound with incidental finding of a nodule in the posterior side of the left thyroid lobe. A following thyroid US performed by an endocrinologist allowed the characterization of the lesion as an esophageal pathology, considering the extrathyroidal position, the typical peripheral hyperechoic spots and hypoechoic rim, the connection to the esophagus, and the swallowing connected movement. The patient was addressed to further investigations and finally to anterior pharyngotomy with histological diagnosis of esophageal fibrovascular polyp. Summary. Differential diagnosis between thyroid nodules and other neck lesions is important to prevent an unnecessary fine needle aspiration biopsy and to treat the extrathyroidal pathology. In this case, an US performed by an expert endocrinologist allowed detecting an esophageal fibrovascular polyp requiring surgical removal. In conclusion, the possibility of an esophageal pathology, and even fibrovascular polyp, should be considered during US thyroid examination.

    Full Text Available Autoimmune diseases (ADs represent a heterogeneous group of disorders that affect specific target organs or multiple organ systems. These conditions share common immunopathogenic mechanisms (i.e., the autoimmune tautology, which explain the clinical similarities they have among them as well as their familial clustering (i.e., coaggregation. As part of the autoimmune tautology, the influence of environmental exposure on the risk of developing ADs is paramount (i.e., the autoimmune ecology. In fact, environment, more than genetics, shapes immune system. Autoimmune ecology is akin to exposome, that is all the exposures - internal and external - across the lifespan, interacting with hereditary factors (both genetics and epigenetics to favor or protect against autoimmunity and its outcomes. Herein we provide an overview of the autoimmune ecology, focusing on the immune response to environmental agents in general, and microbiota, cigarette smoking, alcohol and coffee consumption, socioeconomic status, gender and sex hormones, vitamin D, organic solvents and vaccines in particular. Inclusion of the autoimmune ecology in disease etiology and health will improve the way personalized medicine is currently conceived and applied.

    Autoimmune diseases damage host tissue, which, in turn, may trigger a stronger immune response. Systems characterized by such positive feedback loops can display co-existing stable steady states. In a mathematical model of autoimmune disease, one steady state may correspond to the healthy state...

    Autoimmune diseases (ADs) represent a heterogeneous group of disorders that affect specific target organs or multiple organ systems. These conditions share common immunopathogenic mechanisms (i.e., the autoimmune tautology), which explain the clinical similarities they have among them as well as their familial clustering (i.e., coaggregation). As part of the autoimmune tautology, the influence of environmental exposure on the risk of developing ADs is paramount (i.e., the autoimmune ecology). In fact, environment, more than genetics, shapes immune system. Autoimmune ecology is akin to exposome, that is all the exposures - internal and external - across the lifespan, interacting with hereditary factors (both genetics and epigenetics) to favor or protect against autoimmunity and its outcomes. Herein, we provide an overview of the autoimmune ecology, focusing on the immune response to environmental agents in general, and microbiota, cigarette smoking, alcohol and coffee consumption, socioeconomic status (SES), gender and sex hormones, vitamin D, organic solvents, and vaccines in particular. Inclusion of the autoimmune ecology in disease etiology and health will improve the way personalized medicine is currently conceived and applied.

The inflammation may parallel or remain isolated from a related inflammatory cascade in the thyroid called Graves’ disease. The orbital manifestations can lead to severe proptosis, dry eyes, strabismus, and optic neuropathy. In this article, we will discuss this unique condition including the ophthalmic findings and management.

    Hydrogen peroxide, generated by thyroid oxidase enzymes, is a crucial substrate for the thyroid peroxidase (TPO)-catalysed biosynthesis of thyroid hormones, thyroxine (T4) and triiodothyronine (T3) in the thyroid gland. It is believed that the H2O2 generation is a limiting step in thyroid hormone synthesis. Therefore, the control of hydrogen peroxide concentration is one of the possible mechanisms for the inhibition of thyroid hormone biosynthesis. The inhibition of thyroid hormone synthesis is required for the treatment of hyperthyroidism and this can be achieved by one or more anti-thyroid drugs. The most widely used anti-thyroid drug methimazole (MMI) inhibits the production of thyroid hormones by irreversibly inactivating the enzyme TPO. Our studies show that the replacement of sulphur in MMI by selenium leads to a selone, which exists predominantly in its zwitterionic form. In contrast to the sulphur drug, the selenium analogue (MSeI) reversibly inhibits the peroxidase-catalysed oxidation and iodination reactions. Theoretical studies on MSeI reveal that the selenium atom in this compound carries a large negative charge. The carbon-selenium bond length in MSeI is found to be close to single-bond length. As the selenium atom exhibits a large nucleophilic character, the selenium analogue of MMI may scavenge the hydrogen peroxide present in the thyroid cells, which may lead to a reversible inhibition of thyroid hormone biosynthesis.

    Full Text Available Chikungunya infection has recently re-emerged as an important arthropod-borne disease in Thailand. Recently, Southern Thailand was identified as a potentially endemic area for the chikungunya virus. Here, we report a case of severe musculoskeletal complication, presenting with muscle weakness and swelling of the limbs. During the investigation to exclude autoimmune muscular inflammation, high titers of antinuclear antibody were detected. This is the report of autoimmunity detection associated with an arbovirus infection. The symptoms can mimic autoimmune polymyositis disease, and the condition requires close monitoring before deciding to embark upon prolonged specific treatment with immunomodulators.

    Human herpesvirus 6 (HHV-6) infection is common and has a worldwide distribution. Recently, HHV-6A and HHV-6B have been reclassified into two distinct species based on different biological features (genetic, antigenic, and cell tropism) and disease associations. A role for HHV-6A/B has been proposed in several autoimmune disorders (AD), including multiple sclerosis (MS), autoimmune connective tissue diseases, and Hashimoto's thyroiditis. The focus of this review is to discuss the above-mentio...

    Congenital hypothyroidism is the most common preventable cause of mental retardation. It is important to know the cause of each patient's thyroid dysfunction to foresee the course of therapy and outcomes. Imaging methods, such as ultrasound and thyroid scan, help determine the anatomy and function of the thyroid gland. Although thyroid scan is considered superior in detecting ectopic thyroid tissue, ultrasound is able to detect the presence of thyroid tissue not otherwise visualized in 15% of patients.

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

    Our study was designed to assess the effect of heavy metals on the severity of fatigue in autoimmune thyroid disease associated with autoantibodies against other endocrine organs. We compared our data with those obtained from other groups of patients. A total of five groups of patients were examined by their medical history, dental examination, and using a modified test of blast transformation of metals (Melisa): a) 10 fatigues female patients with autoimmune thyroidism and polyglandular activation of autoimmunity, b) 12 fatigued patients with autoimmune thyroidism, c) 28 fatigued patients free of endocrinopathy, d) 22 professionals without evidence of autoimmunity, e) 13 controls, a population sample, the individuals did not complain of marked fatigue and their laboratory tests did not show signs of autoimmunity and endocrinopathy. Fatigue regardless of the underlying disease is primarily associated with hypersensitivity to inorganic and organic mercury, nickel, and gold. The groups differed in their hypersensitivity to other metals. In the control group, hypersensitivity--mostly to cadmium and lead--was found in four of the examined individuals only. Statistical analysis of data obtained from professionals and controls revealed a higher incidence of positivity to organic and inorganic mercury and nickel in professionals. PMID:10951876
