3D printed, personalized cortisol for cortisol deficiencies

Ayyoubi Sejad , Feelders Richard , Ruijgrok Liesbeth

Introduction: The current standard of care (SOC) for adrenal insufficiency (AI) is suboptimal due to fluctuating cortisol plasma concentrations. The sub- and supraphysiological cortisol levels, combined with the multi day tablet intake, are associated with negative health outcomes and a poor quality of life. Furthermore, there is a high interindividual difference in the cortisol need, demanding a personalized approach. 3D printing (3DP) has gained momentum within the pharmaceu...

An unusual case of acromegaly

Sheridan Mia , Turtle Emma , Van Look Liesbeth

A 57-year-old woman presented with a 4-week history of lethargy, weight loss, polyuria, and polydipsia. Her only past medical history of note was hypertension for which she was taking lisinopril. On admission her initial investigations showed: glucose 22.6 mmol/l, capillary blood ketones Hi and a metabolic acidosis (H+57.5 nmol/l and HCO3− 13.7 mmol/l). She was commenced on the DKA protocol and her acidosis resolved without complication. She was maintained on ...

A family with euthyroid hyperthyroxinaemia

Penswick Stephanie , Squires Maria , Look Liesbeth Van , Wright Rohana

Background: Euthyroid hyperthyroxinaemia can present a diagnostic challenge. Abnormalities in the binding proteins of thyroid hormones can cause this discordant picture of thyroid function tests, with thyroxine binding globulin being the protein most commonly affected. Familial dysalbuminaemic hyperthyroxinaemia is a rarer cause, and is an autosomal dominant condition which can present with euthyroid hyperthyroxinaemia. This condition is associated with a mutation in albumin w...

Iodine deficiency causing goitre and deranged thyroid function

Penswick Stephanie , Squires Maria , Wright Rohana , Van Look Liesbeth

Background: Iodine deficiency is a well known cause of goitre and abnormal thyroid function but is rare in patients born in the UK. Iodine is primarily found in fish and dairy products and patients who avoid these foods may be at risk of iodine deficiency.Case: A 22 year old gentleman was referred to endocrine clinic with an unusual pattern of thyroid function tests (TFTs). He had a goitre on examination. He had a background of irritable bowel syndrome a...

Patient-Derived medullary thyroid cancer organoids; a model for patient-tailored drug and tracer screening

Jager Eline , Sondorp Luc , Antunes Ines , Jansen Liesbeth , Brouwers Adrienne , Links Thera , Coppes Robert , Kruijff Schelto

Background: Medullary thyroid carcinoma (MTC) is a neuroendocrine tumor derived from the parafollicular C-cells of the thyroid gland. Mutations in the gene encoding the Rearranged during Transfection (RET) tyrosine kinase, play a vital role in the development of MTCs. In patients with distant metastases, only targeted therapy can prolong survival. Tyrosine kinase inhibitors (TKIs) block tyrosine kinases such as RET and thereby inhibit tumor proliferation. However, it is diffic...

Prescription of levothyroxine and concurrent use of anti-arrhythmic and bone-anti-resorptive drugs in belgium: retrospective study in a large population sample

Boets Liesbeth , Van Den Bruel Annick , Van Haecht Chris , Debbaut Bernard , Ntahonganyira Rose-Marie , Cornelis Koen , Stokx Jocelijn , Decallonne Brigitte

Background and objective: Increased prescription of levothyroxine (LT4) has been observed in the USA and countries in Europe and has been related to increased thyroid function screening and a lower treatment threshold, increasing risk for overdiagnosis and overtreatment. We wanted to study the evolution of LT4 prescriptions in Belgium, and compare the use of anti-arrhythmic drugs (AAD) and bone-anti-resorptive drugs (BAD) between LT4-users and non-LT4-users.<p class="abste...

Long-term glucocorticoids are associated with increased odds of metabolic syndrome after an intensive combined lifestyle intervention

Mohseni Mostafa , Van der Valk Eline S. , Lengton Robin , Savas Mesut , Rijke Yolanda De , Van den Berg Sjoerd A.A. , Van der Voorn Bibian , Van Rossum Liesbeth F.C

BackgroundLong-term glucocorticoids, as measured in scalp hair (HairGC), are associated with obesity and the metabolic syndrome (MetS). It is not known whether this represents a state of obesity or whether chronic hypercortisolism may influence the course or reversibility of obesity. In this study we longitudinally examine the relation between HairGC concentrations and metabolic syndrome parameters in patients with obesity who participate in a 1.5 year i...

High local and systemic expression of pentraxin-3 in anaplastic thyroid cancer

Bojoga Andreea , van Houten Pepijn , Jaeger Martin , Rabold Katrin , Ioachim Dumitru , Walgreen Birgitte , van Emst Liesbeth , Badiu Corin , Teodora Netea-Maier Romana

Introduction: Long pentraxin 3 (PTX3), a protein cells produce in response to several inflammatory stimuli, is essential in innate immunity, controlling inflammation, tissue remodeling, and cancer dynamics. PTX3 promotes the migration and invasion of cells in different tumor models. This study aims to (I) immunohistochemically assess the presence and distribution of PTX3 in tissue samples from non-medullary thyroid cancer (NMTC) and (II) (TC) to determine the differences of ci...

The role of progesterone in male physiology is mainly unknown. We recently observed that progesterone was the most abundant sex hormone in orchiectomized (ORX) mice with most of it stored in white adipose tissue (WAT) (1). The aim of the present study was to use a sensitive and validated gas chromatography/tandem mass spectroscopy method to determine the origins of progesterone in male mice. Tissue levels of progesterone were high in adrenals of male mice, indicating that male...
