Endocrine Abstracts

In the West of Scotland there is a monthly joint Genetic / Endocrine clinic aiming to centralise management and ensure appropriate screening of individuals with, or at risk of, hereditary endocrine disorders including MEN. This clinic has a designated Genetic Counsellor as well as Consultant Geneticist, Endocrine Nurses and Endocrine Clinicians. The successful collaboration between the departments has led to an increase in expertise on both sides and awareness of the other spe...

Introduction: The NPDA presents data on management, treatment, and complications for all diabetes units in the country. This acts as a driver for quality improvement and aims to improve standards of diabetes care. The 2019 report identified a relatively high proportion of children with hypertension locally. An audit aimed to identify the proportion of local diabetes patients with ‘hypertension’ or ‘pre-hypertension’, and their clinical identification. The s...

Cytochrome P450arom (aromatase), a marker of granulosa cell differentiation, and CTGF mRNA expression are inversely related in the developing rat follicle, but the cause/effect nature of the relationship is not known. Here, we used semi-quantitative in situ hybridization to analyze the expression of these genes during follicular development in the rat. The effect of CTGF on aromatase enzyme activity in isolated granulosa cells was determined by conversion of ...

Phaeochromocytomas (PHAEOs) and extra-adrenal paragangliomas (PGLs) are rare neuroendocrine tumours. As many as 35% may have an identifiable germline mutation, most commonly in the genes encoding RET, VHL or subunits of succinate dehydrogenase (SDHx).[123I]-labelled metaiodobenzylguanidine (123I-MIBG) scintigraphy is used to localise PHAEOs/PGLs, while 131I-MIBG is used as therapy in malignant disease. Uptake of radioisot...

Introduction: Patients with mutations in the Succinate Dehydrogenase Complex Subunit B (SDHB) gene are predisposed to neuroendocrine tumours such as parangangliomas, phaeochromocytomas and gastrointestinal stromal tumours. Individuals who are carriers but have no manifestation of disease require regular surveillance. Our tertiary endocrine service provides follow up/surveillance for these patients and we cover a wide geographical area throughout the West of Scotland.<p cla...

Introduction: Loss of function mutations in SGPL1, a key component of sphingolipid metabolism, are associated with accumulation of sphingolipid intermediates giving rise to a multisystemic disease incorporating primary adrenal insufficiency (PAI) and progressive renal and neurological disease. Sphingolipid accumulation is implicated in mitochondrial pathology.Objective: To investigate the impact of SGPL1 deficiency on mitochondrial morphology/ f...

Vandetenib has been used as novel treatment of locally invasive medullary carcinoma of thyroid. We report the use of Vandetenib in a paediatric patient with inoperable medullary carcinoma of thyroid gland. Our patient presented to the dental surgeons at age 12 years with tongue and lip swellings. Biopsy demonstrated mucosal neuromas suggestive of MEN2B. He was clinically euthyroid but had a firm goitre. Ultrasound showed a large heterogenous thyroid mass encasing the common ca...

Background: Early glycaemic control improves long-term outcomes in children with Type I diabetes. The NICE target for children with T1DM is HbA1c ≤ 48 mmol/mol. 2018 data from our newly diagnosed patients (pre-QI) demonstrated mean HbA1c 50 mmol/mol at 3 months and 62 mmol/mol at 12 months.Aims and methods: Our aim is to improve average blood glucose levels at day 28 post diagnosis and achieve a median HbA1c of <48 mmol/mol at 3 and 12 months p...

Triple A syndrome (AAAS) is a rare, incurable, homozygous disorder, characterised by tissue-specific degeneration resulting in adrenal failure and neurodisability. The AAAS gene encodes ALADIN, a nuclear pore complex (NPC) protein necessary for nuclear import of DNA protective molecules, important for redox homeostasis. ALADIN’s role is not fully characterised: its discovery at the centrosome and the endoplasmic reticulum suggests a role outside the NPC. The inte...

Phaeochromocytomas (PHAEO)/paragangliomas (PGL) are neuro-endocrine tumours. They may present sporadically or as the primary abnormality in a number of familial syndromes. Advances in molecular genetics have led to the identification of several PHAEO/PGL predisposing genes including VHL, NF1 and RET. Mutations in the genes encoding the subunits of Succinate Dehydrogenase (SDH) have also been reported. We describe the phenotype of a cohort of patients with a Succinate Dehydroge...
