BACKGROUND: Vitamin D preparations reduce titers of thyroid antibodies in women with autoimmune thyroiditis. The same effect was induced by high-dose, but not moderate-dose-, statin therapy. No previous study has investigated the impact of concomitant treatment with a statin and vitamin D on thyroid autoimmunity. METHODS: The study included three matched groups of women with Hashimoto's thyroiditis and low vitamin D status. Groups B (n = 19) and C (n = 20) were treated with vitamin D (2000 IU daily)...

In Autoimmune disease a combination of infection, genetic and environmental factors causes an autoimmune response to the thyroid gland (characterized by lymphocytic infiltrations), thyroid stimulating hormone receptor (TSHR) and different thyroid antigens. Graves' and Hashimoto disease are autoimmune disorders with genetic predisposition. CD40 that stimulates the proliferation and differentiation of lymphocytes is an essential immunomodulatory component for follicular cells in the thyroid and the cell that present the antigen...

BACKGROUND: Hashimoto's thyroiditis (HT) is an organ-specific autoimmune disease in which both genetic predisposition and environmental factors serve as disease triggers. Many studies have indicated that alterations in the gut microbiota are important environmental factors in the development of inflammatory and autoimmune diseases. We systematically performed a comparative analysis of the gut microbiota in HT patients and healthy controls. METHODS: We first conducted a cross-sectional study of 28 HT patients and 16 matched healthy controls...

PURPOSE: Studies of cytotoxic T cells and their respective lineage master regulators have been limited in Hashimoto's thyroiditis (HT). It is unclear whether their transcriptomes are changed in HT patients and how these changes are associated with the thyroid damage, major clinical manifestations, and disease progression. METHODS: We explored the gene expression patterns of selected transcription factors [eomesodermin (EOMES), BACH2, BCL6, TCF1] and cytolytic molecules [granzyme B (GZMB)] in peripheral blood (PB) T cells of 10 healthy controls and 30 HT patients of various subtypes (hypothyroid, untreated HT; L-thyroxine (T4)-treated HT, and spontaneously euthyroid HT) using real-time quantitative PCR...

Asthma therapy with monoclonal antibodies is a promising and effective approach for those with a severe and refractory type of disease. Although such a targeted therapy is considered to be safe, unusual complications may occur. We present a case of a 45 year-old female patient with severe allergic asthma and chronic spontaneous urticaria, who developed autoimmune polyendocrine syndrome type 2 (APS-2) after 26 months of omalizumab administration. The patient was diagnosed with primary adrenal insufficiency (Addison's disease) and Hashimoto's thyroiditis accompanied by autoimmune atrophic gastritis...

AIM: Thyroid dysfunction and autoimmunity are associated with an adverse effect on fertility. An aberrant high thyroid stimulating hormone level is associated with diminished ovarian reserve in women of reproductive age; however, the utility of levothyroxine (LT4) replacement for infertile patients with subclinical hypothyroidism is still under discussion. The aim of this study was to investigate whether LT4 supplementation for infertile patients with subclinical hypothyroidism improves impaired ovarian function...

PURPOSE: Hyperhomocysteinemia is a known cardiovascular risk factor and a key player in the inflammatory activation of autoimmune diseases. Hashimoto's thyroiditis (HT) is the leading cause of hypothyroidism which, in itself, has been associated with a significant raise of homocysteine (Hcy) levels and increased cardiovascular risk. Our aim was to assess the impact of HT on Hcy levels in patients with acute hypothyroidism. METHODS: We prospectively enrolled 121 patients (mean age: 46 years, F/M = 102/19) with acute post-surgical hypothyroidism...

A 51-year-old woman with a history of asthma and Hashimoto's thyroiditis presented to the dermatology service with a chief complaint of "itchy bumpy rashes" that persisted beyond 24 hours. She noted that, 3 days prior to the onset of urticaria, a pyrroloquinoline quinone supplement had been started. The urticaria was accompanied by variable episodes of transient facial swelling and difficulty breathing. The patient noted that exposure to fish, nuts, and nonsteroidal anti-inflammatory drugs triggered facial swelling...

PKCε is implicated in T cell activation and proliferation and is overexpressed in CD4+ -T cells from patients with autoimmune Hashimoto's Thyroiditis. Although this might induce the suspicion that PKCε takes part in autoimmunity, its role in the molecular pathophysiology of immune-mediated disorders is still largely unknown. We studied PKCε expression in circulating CD4+ -T cells from patients with Psoriasis, a skin disorder characterized by an increased amount of Th17 cells, a CD4+ subset that is critical in the development of autoimmunity...

Background: Hashimoto thyroiditis (HT) is the most frequent cause of acquired hypothyroidism in paediatrics. HT is usually diagnosed in older children and adolescents, mainly in females and is rare in infants and toddlers with cardiac involvement, including pericardial effusion, that can be found in 10% to 30% of adult HT cases. In this paper, a child with HT and pericardial effusion as the most important sign of HT is described. Case presentation: A four-year-old male child suffering for a few months from recurrent abdominal pain sometimes associated with vomiting underwent an abdominal ultrasound scan outside the hospital...

Acinic cell carcinoma of the parotid gland is a rare low-grade malignant neoplasm. Data on children are sparse. For the present study, the database of a tertiary pediatric medical center was reviewed for all patients with parotid gland acinic cell carcinoma diagnosed and treated between 2004 and 2013. Clinical, histologic, treatment, and outcome parameters were collected from the medical files. Four patients were identified, 3 female and 1 male, aged 13.5 to 18 years (median 15.7) at diagnosis. One patient had a family history of parotid tumor and 1 of hypothyroidism/hyperthyroidism...

Here, we report a case of hemophilia A with myocarditis, encephalopathy, and spontaneous intramedullary hemorrhage. A 14-month-old male infant presented with loss of consciousness, generalized tonic-clonic convulsions, and cardiac failure. The neurological examination was normal. Myocarditis was diagnosed. After administration of fresh frozen plasma, the aPTT did not return to normal. The factor VIII (FVIII) level was 10.2% the normal level, and the patient was diagnosed with hemophilia A. The cerebrospinal fluid (CSF) evaluation was unremarkable, with the exception of elevated CSF protein levels...

Autoimmune thyroid disease (AITD), including Hashimoto's thyroiditis (HT) and Graves' disease (GD), is the most common autoimmune disorder in the United States, affecting over 20 million people. At the time of diagnosis, both HD and GD are characterized by the accumulation of B and T lymphocytes in the thyroid gland and production of autoantibodies targeting the thyroid, indicating that a breach in tolerance of autoreactive lymphocytes has occurred. However, few studies have sought to understand the underlying pathogenesis of AITD that ultimately leads to production of autoantibodies and loss of thyroid function...

Oncogene-induced senescence (OIS) explains the phenomenon of cellular senescence triggered by the action of oncogenes. It is a mechanism adopted by a cell to inhibit progression of benign tumors into malignancy, occurs in premalignant lesions, and is almost never present in malignant lesions. BRAF mutations occur in about 40-45% of all papillary thyroid carcinomas (PTCs) and of which 99.7% is the BRAFV600E mutation. A unique phenotype of the BRAFV600E mutation is the upregulation of the thyroid-stimulating hormone receptor (TSHR) on thyrocyte membranes...

The immune mechanism underlying Hashimoto's thyroiditis (HT) remains unclear. CD26, also known as dipeptidyl peptidase 4 (DPP-4), is a multifunctional molecule involved in the pathophysiology of autoimmune diseases. This study aimed to investigate the role of CD26 in the pathogenesis of HT. Peripheral blood was drawn from 20 healthy controls and 31 HT patients (19 mild HT patients and 12 severe HT patients). Plasma sCD26 concentrations were measured by ELISA, and sCD26 enzymatic activity was assessed using a luciferase-based assay...

Autoimmune Thyroid Diseases (AITDs), including Hashimoto's thyroiditis (HT) and Graves' disease (GD), arise by the complex interaction of genes and environmental factors. The aim of present study was to study the susceptible associations of HLA-DRB1* alleles and CTLA4 +49 AG polymorphism in AITD in south India. AITD patients (n=235; HT=180; GD=55) and age/sex matched healthy controls (n, 235) were enrolled to type HLA-DRB1* alleles and 'CTLA4 +49 AG' by PCR-SSP and PCR-RFLP methods respectively. Analysis revealed CTLA4 +49 'GG' genotype was increased significantly in patients (PL: p=8...
