Ciclosporin and thyroid-stimulating immunoglobulins in endocrine orbitopathy.
1989
The study investigated whether ciclosporin (C) affected the thyroid-stimulating immunoglobulins (TSI) in serum of patients with endocrine orbitopathy (EO). The effect of C was compared with that of prednisone (P). Fifteen patients with EO classes III-V received C (n = 7) or P (n = 8). In addition to the immunosuppressants, five patients with Graves' disease in each group received methimazole (MMI). The stimulation of the cAMP levels in the medium of thyrocyte cultures was determined as a parameter of TSI. The TSI levels were markedly lowered in both groups during and after therapy. C group: before therapy 6.2 pmol/ml +/- 1.63 (100%, mean +/- SEM), during treatment 4.6 pmol/ml +/- 2.28 (74%)…
Outcome of orbital decompression for disfiguring proptosis in patients with Graves' orbitopathy using various surgical procedures
2009
Aim: To compare the outcome of various surgical approaches of orbital decompression in patients with Graves' orbitopathy (GO) receiving surgery for disfiguring proptosis.Method: Data forms and questionnaires from consecutive, euthyroid patients with inactive GO who had undergone orbital decompression for disfiguring proptosis in 11 European centres were analysed.Results: Eighteen different (combinations of) approaches were used, the swinging eyelid approach being the most popular followed by the coronal and transconjunctival approaches. The average proptosis reduction for all decompressions was 5.0 (SD 2.1) mm. After three-wall decompression the proptosis reduction was significantly greater…
Immunohistochemical Staining of Retrobulbar Adipose Tissue in Graves' Ophthalmopathy
1994
An increase of retrobulbar adipose tissue has been shown by imaging techniques in patients with Graves' ophthalmopathy (GO). Immunohistochemical staining was applied to investigate the involvement of different retrobulbar (especially adipose) tissue components in the autoimmune process of the disease. Cryostat sections from retrobulbar tissues of 15 GO patients and 11 controls were analyzed with a battery of monoclonal antibodies against CD2, CD4, CD8, CD11a, CD19/22, CD25, CD54, CD57, CD68, C3b, HLA-A, B, C, and HLA-DR. In contrast to controls, the retrobulbar adipose tissue showed an increase of HLA-DR expression, an activation of intercellular adhesion molecule I (ICAM-1, CD54), as well …
Impaired Cardiopulmonary Exercise Capacity in Patients With Hyperthyroidism
1996
Hyperthyroidism (H) has been implicated as a primary cause of decreased exercise tolerance. To our knowledge, analysis of respiratory gas exchange, an efficient noninvasive method in evaluating cardiopulmonary capacity, has not been performed in patients with H.Using cardiopulmonary exercise testing, 12 consecutive women with Graves' H were examined and controlled in euthyroidism (E). Eighteen women with E, in whom cardiac catheterization had ruled out heart disease, served as control subjects (C).The ventilatory anaerobic threshold was determined by means of the V-slope method. Ergometry was performed with patients in a semisupine position using a continuous ramp protocol of 20 W/min. Echo…
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…
Beyond the grave: variability in Neolithic diets in Southern Germany?
2006
Abstract Carbon and nitrogen stable isotope analyses were undertaken on human and faunal remains from two Neolithic sites in Southern Germany; the LBK settlement at Herxheim and the middle Neolithic cemetery at Trebur. Stable isotope data were used to reconstruct the diets of individuals buried at these sites and to look at dietary variation between groups classified by their sex, age, grave goods and cultural affiliation. Overall there was surprisingly little variation in the diet between the groups, as described by the stable isotope analysis, despite significant differences in the composition of grave goods. Also surprising, considering the archaeological evidence for extensive grain cul…
Comparative analysis of radical scavenging and antioxidant activity of phenolic compounds present in everyday use spice plants by means of spectropho…
2010
Comparative analysis of radical scavenging and antioxidant activities of phenolic compounds present in everyday use spice plants was carried out by means of spectrophotometric and chromatographic methods. Six spice plant samples, namely onion (Allium cepa), parsley (Petroselinum crispum) roots and leaves, celery (Apium graveolens) roots and leaves and leaves of dill (Anethum graveolens) were analyzed. Total amount of phenolic compounds and radical scavenging activity (RSA) was the highest in celery leaves and dill extracts and was the lowest in celery roots. Comparing commonly used spectrophotometric analysis of 2,2-diphenyl-1-picrylhydrazyl (DPPH) RSA of extracts with the results obtained …
2018 European Thyroid Association Guideline for the Management of Graves' Hyperthyroidism.
2018
Graves' disease (GD) is a systemic autoimmune disorder characterized by the infiltration of thyroid antigen-specific T cells into thyroid-stimulating hormone receptor (TSH-R)-expressing tissues. Stimulatory autoantibodies (Ab) in GD activate the TSH-R leading to thyroid hyperplasia and unregulated thyroid hormone production and secretion. Diagnosis of GD is straightforward in a patient with biochemically confirmed thyrotoxicosis, positive TSH-R-Ab, a hypervascular and hypoechoic thyroid gland (ultrasound), and associated orbitopathy. In GD, measurement of TSH-R-Ab is recommended for an accurate diagnosis/differential diagnosis, prior to stopping antithyroid drug (ATD) treatment and during p…
The role of fire within Neolithic collective burials: Spatial analyses of cremains from the site of La Truie Pendue, France
2016
International audience; The use of collective graves is one of the main features of the western European Late Neolithic. A single gravesite received the successive deposition of dozens or sometimes hundreds of individuals. While cremations or even full-fired inhumation layers are often found within these funerary deposits, the actual role of fire is still poorly understood. Recently discovered within the important archaeological complex of Passy (Yonne, France), the burned collective grave of La Truie-Pendue provides an outstanding case study to examine the use of fire within Neolithic funerary rites. In this study, we develop a new contextual approach to bone alterations in order to recons…
