Horm Metab Res

September 2019

Department of Endocrinology, Diabetes and Metabolism, Clinical Chemistry - Division of Laboratory Research, University Hospital Essen, University Duisburg-Essen, Essen, Germany.

The aim of this study was to investigate in a longitudinal approach whether levothyroxine (LT4) substitution has a different impact on quality of life (QoL) and thyroid related QoL in younger (<40 years) and older subjects (>60 years) with elevated thyroid-stimulating hormone (TSH) concentrations. The study included male and female patients with newly diagnosed, untreated subclinical hypothyroidism defined by TSH>8 mU/l. Patients were recruited throughout Germany from 2013-2016 and evaluated by clinical assessment, blood sampling and questionnaires for health related QoL and thyroid-disease thyroid-related QoL (ThyPRO) at time of diagnosis and six months after initiation of LT4 treatment.

The number of patients surviving ≥5 years after initial cancer diagnosis has significantly increased during the last decades due to considerable improvements in the treatment of many cancer entities. A negative consequence of this is that the emergence of long-term sequelae and endocrine disorders account for a high proportion of these. These late effects can occur decades after cancer treatment and affect up to 50% of childhood cancer survivors.

2018 European Thyroid Association (ETA) Guidelines on the Diagnosis and Management of Central Hypothyroidism.

Eur Thyroid J

October 2018

Department of Pediatric Endocrinology, Emma Children's Hospital, Academic Medical Center, University of Amsterdam, Amsterdam, the Netherlands.

Objectives: Central hypothyroidism (CeH) is a rare form of hypothyroidism characterized by insufficient thyroid stimulation due to disturbed pituitary and/or hypothalamic functioning. Due to its origin and the whole clinical context, CeH represents a challenging condition in clinical practice as it is characterized by suboptimal accuracy of clinical and biochemical parameters for diagnosis and management. Since no expert consensus or guidance for this condition is currently available, a task force of experts received the commitment from the European Thyroid Association (ETA) to prepare this document based on the principles of clinical evidence.

Copeptin as a marker of an altered CRH axis in pituitary disease.

Endocrine

September 2017

Experimental and Clinical Endocrinology Med Clinic I, University of Luebeck, Ratzeburger Allee 160, 23538, Lübeck, Germany.

Background: Copeptin (pre-proAVP) secreted in equimolar amounts with vasopressin closely reflects vasopressin release. Copeptin has been shown to subtly mirror stress potentially mediated via corticotrophin-releasing hormone. To further test a potential direct interaction of corticotrophin-releasing hormone with copeptin release, which could augment vasopressin effects on pituitary function, we investigated copeptin response to corticotrophin-releasing hormone.

Differential regulation of monocarboxylate transporter 8 expression in thyroid cancer and hyperthyroidism.

Eur J Endocrinol

September 2017

Department of Endocrinology and Metabolism and Division of Laboratory Research, University of Duisburg-Essen, Essen, Germany.

Objective: Thyroid hormone (TH) transporters are expressed in thyrocytes and most play a role in TH release. We asked whether expression of the monocarboxylate transporter 8 (MCT8) and the L-type amino acid transporters LAT2 and LAT4 is changed with thyrocyte dedifferentiation and in hyperfunctioning thyroid tissues.

Design And Methods: Protein expression and localization of transporters was determined by immunohistochemistry in human thyroid specimen including normal thyroid tissue (NT,  = 19), follicular adenoma (FA,  = 44), follicular thyroid carcinoma (FTC,  = 45), papillary thyroid carcinoma (PTC,  = 40), anaplastic thyroid carcinoma (ATC,  = 40) and Graves' disease (GD,  = 50) by calculating the 'hybrid' (H) score.

Plasma proteome and metabolome characterization of an experimental human thyrotoxicosis model.

BMC Med

January 2017

Medical Clinic I, University of Lübeck, Experimental and Clinical Endocrinology, Ratzeburger Allee 160, Zentralklinikum (Haus 40), 23538, Lübeck, Germany.

Background: Determinations of thyrotropin (TSH) and free thyroxine (FT) represent the gold standard in evaluation of thyroid function. To screen for novel peripheral biomarkers of thyroid function and to characterize FT-associated physiological signatures in human plasma we used an untargeted OMICS approach in a thyrotoxicosis model.

Methods: A sample of 16 healthy young men were treated with levothyroxine for 8 weeks and plasma was sampled before the intake was started as well as at two points during treatment and after its completion, respectively.

Potential Clinical Utility of Copeptin (C-terminal provasopressin) measurements in clinical medicine.

Exp Clin Endocrinol Diabetes

March 2016

Experimental and Clinical Endocrinology Med Clinic I, University of Luebeck, Germany.

Copeptin is a 39-amino-acids containing glycosylated peptide derived from the C-terminal part of the arginine vasopressin (AVP) precursor. In the process of proteolysis the AVP precursor is processed to AVP, neurophysin II, and copeptin in equimolar amounts. In contrast to AVP, copeptin remains stable for several days at room temperature in serum or plasma.

Copeptin under glucagon stimulation.

Endocrine

May 2016

Experimental and Clinical Endocrinology Med Clinic I, University of Luebeck, Ratzeburger Allee 160, 23538, Lübeck, Germany.

Stimulation of growth hormone (GH) and adrenocorticotropic hormone (ACTH) secretion by glucagon is a standard procedure to assess pituitary dysfunction but the pathomechanism of glucagon action remains unclear. As arginine vasopressin (AVP) may act on the release of both, GH and ACTH, we tested here the role of AVP in GST by measuring a stable precursor fragment, copeptin, which is stoichiometrically secreted with AVP in a 1:1 ratio. ACTH, cortisol, GH, and copeptin were measured at 0, 60, 90, 120, 150, and 180 min during GST in 79 subjects: healthy controls (Group 1, n = 32), subjects with pituitary disease, but with adequate cortisol and GH responses during GST (Group 2, n = 29), and those with overt hypopituitarism (Group 3, n = 18).

A GH variant of placental origin, placental GH, has recently been shown to replace pituitary GH in maternal serum during pregnancy. Besides, the GH variant (GH-V) gene has been demonstrated to be expressed in the placenta. The similarities between their known properties strongly suggest that the placental GH and the GH-V protein are the same molecular species.
