Background: Functioning gonadotroph adenomas (FGA) are rare benign pituitary tumours. Several case reports suggest that FGA may present with features of ovarian hyperstimulation in women. However, a lack of aggregated clinical experience of FGA precludes the meaningful guidance of management in affected women.Methods: Case series of 7 women presenting at different UK sites with FGA induced ovarian hyperstimulation syndrome (OHSS).R...

Background: Cabergoline monotherapy or in combination with somatostatin analogue (SSA) has been reported in few studies with IGF-1-normalization-rates 0%-100%(monotherapy) and 42%-60%(combination therapy). However, in these studies, inclusion of irradiated patients is a potential confounder and currently proposed disease control criteria (normal IGF-1, GH<1 mg/l) have not been applied.Aim: Investigate the efficacy of cabergoline monotherapy or as add...

Introduction: Cabergoline is one of the medical treatments in acromegaly; it can be used alone or in combination with other available agents.Aim: To review the efficacy of cabergoline in patients with acromegaly treated in our centre.Patients and methods: Patients with acromegaly on cabergoline were identified from our Pituitary Registry. Clinical/laboratory/imaging data were collected and analysed.Results: F...

Introduction and aim: Pancreatic neuroendocrine tumours (PNETs) may occur sporadically (sPNETs) or as part of the multiple endocrine neoplasia type 1(MEN1) syndrome, which is characterised by occurrence of PNETs, parathyroid and anterior pituitary tumours. Our aim was to review the management of these patients in relation to the clinical practice MEN1 guidelines, and the ENETS and UKINETS guidelines for PNETs.Patients and methods: Patients attending with...

Patients with adrenal insufficiency require increased hydrocortisone (HC) replacement doses during surgery, trauma and infection to avoid life-threatening adrenal crisis. However, currently administered HC doses are chosen empirically rather than on rational grounds, with huge variability in administration modes, total dose and dosing intervals. To conclusively determine serum cortisol levels observed under stress conditions, we firstly collected blood samples from healthy con...

Patients with adrenal insufficiency (AI) require adjustment of hydrocortisone (HC) dose to avoid life-threatening adrenal crisis during illness, surgery and trauma. However, current dose recommendations are based on empirical grounds only and choice of dose and administration modes vary considerably. We designed the PACS study to compare cortisol levels achieved by currently recommended HC stress doses to those in i) healthy controls (n=85, 21–70 years), ii) mili...

Background: Central diabetes insipidus (cDI), a rare neuroendocrine condition affecting 1 in 25.000, is characterized by deficiency of arginine vasopressin. Data about treatment-related side effects, psychological co-morbidities, and incidence of wrong management due to confusion with diabetes mellitus are scarce and limited to small studies or case series. Furthermore, increasing interest has arisen on a potential need for re-naming the condition.<p class="abstex...

Introduction: Silent somatotroph Pituitary Neuroendocrine Tumours (PitNETs) are extremely rare (2−3% of surgically treated pituitary tumours) and data on their natural history and outcomes are scarce.Aim: To review systematically the cases of these tumours presenting in our Centre.Patients and methods: Patients with this diagnosis were identified from our Pituitary Registry and clinical/laboratory/imaging data were collected ...

Background: Metastatic disease in the pituitary (PM) is uncommon and the published literature mainly involves case reports and small case series. We aimed to analyze presenting manifestations and outcomes of patients diagnosed with PM in our pituitary centre.Methods: Retrospective review of our Pituitary Registry to identify patients with PM from 2006 to present. Clinical, radiological, and pathological data were collected and analysed.<p class="abst...

Introduction: Functioning gonadotroph adenomas (FGAs) are very rare tumours secreting biologically active gonadotropins. In males, typically, FSH levels are elevated, whereas LH and testosterone are variable. Herein, we present three males with elevated, normal or low testosterone at diagnosis.Cases: Case 1:42-year-old man with two-year history of visual impairment. Bitemporal hemianopia was confirmed. Imaging showed macroadenoma compressing optic chiasm...
