Autoimmunity Features in Patients With Non-Celiac Wheat Sensitivity.

2021

INTRODUCTION: Nonceliac wheat sensitivity (NCWS) is characterized by intestinal and extraintestinal manifestations consequent to wheat ingestion in subjects without celiac disease and wheat allergy. Few studies investigated the relationship between NCWS and autoimmunity. The aim of this study is to evaluate the frequency of autoimmune diseases (ADs) and autoantibodies in patients with NCWS. METHODS: Ninety-one patients (13 men and 78 women; mean age of 40.9 years) with NCWS, recruited in a single center, were included. Seventy-six healthy blood donors (HBD) and 55 patients with a diagnosis of irritable bowel syndrome (IBS) unrelated to NCWS served as controls. Autoantibodies levels were mea…

Ciamexone in endocrine orbitopathy. A randomized double-blind, placebo-controlled study.

1990

Abstract The influence of ciamexone on the activity and course of endocrine orbitopathy was investigated. Fifty-one patients with active orbitopathy classes II-VI were allocated randomly to two groups: over a period of six months, 26 patients received 300 mg/day ciamexone and 25 patients received placebo tablets. In both groups, prednisolone was administered in addition in the first four weeks. Ophthalmological investigations and clinical tests as well as orbit sonography were carried out before as well as one, three and six months after the beginning of therapy. Before and after treatment, computer tomography of the orbit was performed. Symptoms and signs did not show any significant impro…

Evaluation of Xerostomia and salivary flow rate in Hashimoto’s Thyroiditis

2015

Background: One of the most common causes of hypothyroidism is Hashimoto´s Thyroiditis (HT). Early detection of dry mouth is critical in preserving and promoting systemic and oral health. In this study we have assessed, for the first time, salivary function and xerostomia in HT patients who have not been involved with Sjögren´s syndrome. Material and Methods: HT was diagnosed in 40 patients based on clinical findings and positive anti-thyroid peroxidase antibodies (anti-TPO). Controls, matched by sex, age and body mass index (BMI), and with no history of thyroid disease, were selected. A questionnaire was used for diagnosis of xerostomia. Saliva samples were taken between 8 a.m. and 9 a.m.,…

Control of target cell survival in thyroid autoimmunity by T helper cytokines via regulation of apoptotic proteins

2000

After autoimmune inflammation, interactions between CD95 and its ligand (CD95L) mediate thyrocyte destruction in Hashimoto's thyroiditis (HT). Conversely, thyroid autoimmune processes that lead to Graves' disease (GD) result in autoantibody-mediated thyrotropin receptor stimulation without thyrocyte depletion. We found that GD thyrocytes expressed CD95 and CD95L in a similar manner to HT thyrocytes, but did not undergo CD95-induced apoptosis either in vivo or in vitro. This pattern was due to the differential production of TH1 and TH2 cytokines. Interferon gamma promoted caspase up-regulation and CD95-induced apoptosis in HT thyrocytes, whereas interleukin 4 and interleukin 10 protected GD …

Fetal/Neonatal Thyrotoxicosis in a Newborn From a Hypothyroid Woman With Hashimoto Thyroiditis.

2016

Context: Fetal/neonatal thyrotoxicosis is a rare but potentially life-threatening condition. It is most commonly observed in poorly controlled Graves’ disease during pregnancy. Case Description: Here we describe the first reported case of thyrotoxicosis in a fetus/newborn from a woman with Hashimoto’s thyroiditis and levothyroxine-treated hypothyroidism. Transplacental passage of stimulating TSH-receptor antibodies, measured by a cell-based bioassay, was the underlying mechanism of fetal/neonatal thyrotoxicosis even though the mother had no history of hyperthyroidism. Conclusion: Diagnosis and management of fetal hyperthyroidism can be challenging. TSH receptor antibody testing should be co…

Subclinical hypothyroidism resulting from autoimmune thyroiditis in female patients with endogenous depression.

1994

Thyroid function and presence of thyroid autoantibodies were assessed in a group of 75 consecutive female patients with mood disturbances and in a group of 38 healthy women of similar age recruited as controls. Nine patients suffered from major (endogenous) depression and 66 from minor (neurotic) depression. The individual patients had normal values of circulating thyroid hormones. Nevertheless, endogenously depressed patients had total serum triiodothyronine (M±SE=1.49±0.09 nmol/l) and both total (83.9±4.3 nmol/l) and free serum thyroxine (13.9±1.1 pmol/l) lower than in the group of minor depressed and in the group of controls (p<0.01, in both comparison). The median value of serum thyrotr…

Possible link between Hashimoto's thyroiditis and oral lichen planus: a novel association found

2013

Objectives: Hashimoto's thyroiditis as well as lichen planus has been associated to a number of disorders, generally of auto-immune origin. A novel possible association between oral lichen planus (OLP) and Hashimoto's thyroiditis (HT) is here proposed on the basis of a cross-sectional survey. Materials and methods: One hundred and five unrelated OLP patients were considered. Diagnosis of HT was based on positive serum anti-TPO, anti-Tg, TSH levels and the typical ultrasound pattern of the thyroid gland. Results: In the present survey, the prevalence of HT in the OLP group was 14. 3 % whereas the prevalence of HT-related hypothyroidism in the general population was reported to be equal to 1 …

B7.1 Costimulatory Molecule Is Expressed on Thyroid Follicular Cells in Hashimoto’s Thyroiditis, But Not in Graves’ Disease1

1998

The molecules of the B7 family play a major role in T-lymphocyte costimulation through interaction with their counterreceptors CD28 and CTLA4. In the present study, we analyzed the possible expression of B7 molecules on surgically removed thyroid tissue of patients with autoimmune [Hashimoto's thyroiditis (HT) or Graves' disease (GD)] or nonautoimmune [nontoxic goiter (NTG) or papillary cancer (PC)] thyroid diseases. We found clear positivity of thyroid follicular cells for B7.1 in HT but not in GD, nor in nonautoimmune specimens (NTG, PC) using in situ analysis by alkaline phosphatase anti-alkaline phosphatase (APAAP) technique. Double immunostaining experiments in combination with an anti…

Das polyglanduläre Autoimmunsyndrom Typ II: Epidemiologie und Manifestationsformen

1999

Background and objective Polyglandular autoimmune syndrome (PAS), is characterized by the coexistence of several autoimmune diseases, affecting predominantly the endocrine glands. The juvenile form (PAS type I) is distinguished from the adult type II in which autoimmune thyroiditis, adrenal cortical insufficiency and diabetes mellitus type I predominate. The connections between epidemiological, clinical and immunological aspects were analysed and described in this study of patients with PAS type II. Patients and methods Among a total patient population of over 15,000 seen in our endocrinological university policlinic from 1992 through 1996, the clinical data of all 151 patients with PAS typ…
