1/92. headache and bilateral visual loss in a young hypothyroid Indian man.We describe the exceptional association of Vogt-Koyanagi-Harada syndrome (VKHS) and hypothyroidism in a 29-year-old man of Indian heritage. VKHS is a rare uveomeningoencephalitic syndrome with probably autoimmune pathogenesis. Nontraumatic uveitis, aseptic meningoencephalitis, vitiligo, alopecia and poliosis are the leading clinical features of VKHS. The reported patient presented with bilateral visual loss and progressive frontal headache. VKHS was diagnosed due to characteristic ophthalmological findings and the diagnosis of aseptic meningitis. Due to the autoimmune pathogenesis, VKHS may be rarely associated with other autoimmune disorders. association of VKHS with autoimmune thyroid disease has been described in the literature in three patients. In the reported case hypothyroidism due to chronic autommune thyroiditis was diagnosed in association with VKHS. Routinely determination of thyroid function in patients with VKHS is recommended.- - - - - - - - - - ranking = 1keywords = thyroiditis (Clic here for more details about this article) |
2/92. autoimmunity and extranodal lymphocytic infiltrates in lymphoproliferative disorders.OBJECTIVE: To examine the relationship between autoimmunity and extranodal lymphocytic infiltrates in different lymphoproliferative disorders with immunoglobulin alterations. SUBJECTS AND DESIGN: A clinical review combined with a retrospective cohort study of 380 patients, 28 with monoclonal gammopathy of undetermined significance, three with common variable immunodeficiency, 147 with chronic lymphocytic leukaemia, 57 with Waldenstrom's macroglobulinaemia and 145 with non-Hodgkin's malignant lymphoma. SETTING: A university hospital and The State serum Institute in Copenhagen. INTERVENTION: Clinical examination of each patient with special attention to chronic inflammatory and autoimmune manifestations. Biopsies were taken from non-infectious infiltrates, some of which were additionally tested with PCR analysis for gene rearrangements. Serological screening with a test battery for various autoantibodies was used in combination with techniques for the detection of M-components and monoclonal B-cell proliferation. MAIN OUTCOME MEASURES: Clinical and/or serological autoimmune manifestations, M-component and other immunoglobulin alterations, and inflammatory tissue changes were studied in patients with chronic inflammatory, polyclonal or oligoclonal pseudolymphomas and in monoclonal, malignant extranodal lymphomas. RESULTS: In 380 consecutive patients, 49 (12.9%) had extranodal manifestations, of whom 47 also had autoimmune manifestations. Nearly half of the 47 patients had more than one autoimmune manifestation. There was a strong correlation between clinical signs and corresponding autoantibodies such as anti-SSA and -SSB antibodies in sjogren's syndrome (10 cases), antithyroid peroxidase antibodies in thyroiditis and Graves' disease (10 cases), and parietal cell antibodies in gastric ulcers with maltoma (12 cases). Clinical and serological signs of autoimmunity correlated strongly with female sex (34, 72% women; and 13, 28% men) and with immunoglobulin alterations. CONCLUSIONS: To our knowledge this is the first systematic review of B-lymphoproliferative and autoimmune disorders indicating that pseudolymphoma and malignant lymphomas, including maltomas, may develop in the context of a permanent autoantigenic drive.- - - - - - - - - - ranking = 1keywords = thyroiditis (Clic here for more details about this article) |
3/92. Autoimmune thyroiditis and myelosuppression following treatment with interferon-alpha for hepatitis c.CASE: We describe the case of a 48-year-old woman from thailand diagnosed with chronic hepatitis c, who experienced a suppression of all blood cell counts accompanied by a newly developed clinically manifested autoimmune thyroid disorder after treatment with interferon alpha-2b (INF-alpha) 46 days after beginning of therapy a decrease of platelet, red and white blood cell counts became obvious. Concomitantly we observed an increase of FT4 and FT3 with a totally depressed TSH level 80 days after starting INF-alpha administration. Antibody assessment resulted in detection of high numbers of antithyroid-microsomal antibodies and antithyroglobulin antibodies. Thyroid hormone levels normalized under treatment with methimazole/propylthiouracil within 4.5 months. However, two months after cessation of antithyroid therapy increasing TSH levels and decreasing FT4 levels indicated a new tendency towards a hypothyroid state. CONCLUSION: We classify this case as an interferon-alpha-induced disorder of thyroid function accompanied by myelosuppression. A close monitoring for thyroid dysfunction, e.g. evaluation of TSH-levels before and after administration of INF-alpha is mandatory.- - - - - - - - - - ranking = 4keywords = thyroiditis (Clic here for more details about this article) |
4/92. Adoptive autoimmune hyperthyroidism following allogeneic stem cell transplantation from an HLA-identical sibling with Graves' disease.autoimmune diseases which follow allogeneic BMT from a donor who is a patient or a carrier of an autoimmune condition are considered to be a paradigm of adoptive autoimmunity. Seven cases of autoimmune thyroiditis associated with clinical hyperthyroidism have been published to date. In the case reported here a 35-year-old female patient with AML of the M2 subtype received unmanipulated PBSC from her HLA-identical sister who had therapeutically controlled Graves' disease. Antithyroid antibodies, including thyrotropin receptor (TSHR) antibodies, appeared 1 year after transplant. Clinical hyperthyroidism requiring thyrostatic medication appeared after 2 years. The biological and clinical implications of adoptive, post-transplant autoimmunity are briefly discussed.- - - - - - - - - - ranking = 2.2001647391954keywords = autoimmune thyroiditis, thyroiditis (Clic here for more details about this article) |
5/92. Unusual association of thyroiditis, Addison's disease, ovarian failure and celiac disease in a young woman.The coexistence of autoimmune endocrine diseases, particularly autoimmune thyroid disease and celiac disease (CD), has recently been reported. We here present a 23-year-old woman with a diagnosis of hypothyroidism due to Hashimoto's thyroiditis, autoimmune Addison's disease, and kariotypically normal spontaneous premature ovarian failure. Considering the close association between autoimmune diseases and CD, we decided to search for IgA anti-endomysium antibodies (EmA) in the serum. The positivity of EmA and the presence of total villous atrophy at jejunal biopsy allowed the diagnosis of CD. On a gluten-free diet the patient showed a marked clinical improvement accompanied, over a 3-month period, by a progressive decrease in the need for thyroid and adrenal replacement therapies. After 6 months, serum EmA became negative and after 12 months a new jejunal biopsy showed complete mucosal recovery. After 18 months on gluten-free diet, the anti-thyroid antibodies titre decreased significantly, and we could discontinue thyroid substitutive therapy. This case emphasizes the association between autoimmune polyglandular disease and CD; the precocious identification of these cases is clinically relevant not only for the high risk of complications (e.g. lymphoma) inherent to untreated CD, but also because CD is one of the causes for the failure of substitute hormonal therapy in patients with autoimmune thyroid disease.- - - - - - - - - - ranking = 5keywords = thyroiditis (Clic here for more details about this article) |
6/92. Lymphocytic hypophysitis associated with dacryoadenitis: an autoimmunologically mediated syndrome.We report a rare case of lymphocytic hypophysitis followed by dacryoadenitis. Lymphocytic hypophysitis is a rare disease that can easily be mistaken for neoplastic proliferation. Because combination with rheumatoid arthritis, thyroiditis, or pernicious anemia is frequent, an immunological pathogenesis is likely.- - - - - - - - - - ranking = 1keywords = thyroiditis (Clic here for more details about this article) |
7/92. Interstitial granulomatous dermatitis with plaques.We report on the clinical and histopathologic findings of four patients who had asymptomatic, erythematous to violaceous plaques symmetrically distributed on the upper aspect of the thighs, lateral chest, and in two cases also on the abdomen and flexor surface of the elbows. All of the patients were women; two of them had arthritis, which in one case was associated with an autoimmune disorder, and another had autoimmune thyroiditis. Histopathologically, all cases showed similar changes consisting of an interstitial granulomatous dermatitis involving mostly the lower reticular dermis. histiocytes were the predominant cellular component, arranged interstitially and in small palisades around foci of degenerated collagen bundles in concert with large numbers of neutrophils and eosinophils. Interstitial granulomatous dermatitis can present different clinical expressions, including linear cords, papules, and, as in our cases, plaques. This peculiar histopathologic pattern falls into the spectrum of cutaneous extravascular necrotizing granuloma, a condition that is often associated with systemic autoimmune disease.- - - - - - - - - - ranking = 2.2001647391954keywords = autoimmune thyroiditis, thyroiditis (Clic here for more details about this article) |
8/92. Non-Hodgkin's lymphoma followed by plasmacytoma, both arising in A thyroid gland with Hashimoto's disease.We describe here a rare case of malignant lymphoma followed by plasmacytoma in Hashimoto's thyroiditis. The patient developed malignant lymphoma (small, non-cleaved cell, and non Burkitt's type by Working Formulation classification), and remained in remission for 2 years after receiving combination chemotherapy, and then developed plasmacytoma in the same lesion. Rearrangement bands for IgH from both specimens showed different bands, indicating that both were of monoclonal type but of a different clonal origin. Considering the clinical course in this case, thyroidectomy may be indicated for lymphoproliferative diseases in Hashimoto's thyroiditis treated with chemotherapy.- - - - - - - - - - ranking = 2keywords = thyroiditis (Clic here for more details about this article) |
9/92. hyponatremia with increased plasma antidiuretic hormone in a case of hypothyroidism.We report a 70-year-old woman with hypothyroidism and severe hyponatremia. Her plasma antidiuretic hormone (ADH) level was inappropriately high for her low plasma osmolality. Her low serum sodium level was gradually corrected by water restriction and sodium supplementation prior to the initiation of thyroid hormone replacement. After a diagnosis of Hashimoto's thyroiditis had been made, the patient was treated with levothyroxine. Following this treatment, the patient's serum sodium level increased drastically. It is suggested that the elevated plasma ADH level played an important role in the development of hyponatremia in this case.- - - - - - - - - - ranking = 1keywords = thyroiditis (Clic here for more details about this article) |
10/92. Autoimmune thyroid dysfunction induced by interferon-alpha treatment for chronic hepatitis c: screening and monitoring recommendations.OBJECTIVE: To analyze the proposed mechanisms of action of recombinant interferon-alpha (IFN-a) in causing autoimmune thyroid dysfunction, to identify pretreatment risk factors, and to provide recommendations for screening and monitoring of thyroid dysfunction during IFN-a therapy for chronic hepatitis c. methods: Selected publications were reviewed to analyze the proposed mechanisms of autoimmune thyroid disorders. In addition, we examined the interrelationship of the thyroid and the liver, the occurrence of thyroid dysfunction in patients with chronic hepatitis c before and after IFN-a therapy, and the presence or absence of antithyroid antibodies in association with thyroid disease. case reports were selected to demonstrate various IFN-a-induced thyroid dysfunction. RESULTS: IFN-a induces thyroid dysfunction in 3 to 14% of all treated patients with chronic hepatitis c, leading to hypothyroidism, hyperthyroidism, or thyroiditis. In a few patients, thyroid disease will develop in the absence of antithyroid antibodies, a scenario that suggests a nonimmune-mediated mechanism. More frequently, patients develop antithyroid antibodies, which may progress to overt thyroid dysfunction. Through its immunomodulatory properties, IFN-a seems to act through major histocompatibility complex class I antigens to produce antithyroid antibodies and thyroid disease. CONCLUSION: In patients receiving IFN-a therapy for chronic hepatitis c infection, identifiable risk factors for developing autoimmune thyroid dysfunction are preexisting overt thyroid or autoimmune disease, subclinical thyroid or autoimmune thyroid disease, and female gender. Pretreatment screening is recommended for all patients in whom IFN-a therapy is being considered, and periodic monitoring should be performed during such therapy. Thyroid disease need not be a contraindication to IFN-a therapy; early detection of subclinical or overt thyroid disease may allow uninterrupted continuation of IFN-a treatment.- - - - - - - - - - ranking = 1keywords = thyroiditis (Clic here for more details about this article) |
