Background: Immune checkpoint inhibitors (ICIs) including programmed-death cell-1 (PD-1), programmed death-ligand 1 (PD-L1) and cytotoxic T-lymphocyte antigen-4 (CTLA-4) re-activate T lymphocytes and promote cancer cell death. Immune-related adverse events (irAEs) are common in cancer patients receiving ICIs. Endocrine irAEs include primary thyroid dysfunction, hypophysitis, type 1 diabetes mellitus (T1DM) and primary adrenal insufficiency. These endocrinopathies may require a...

Background: Correct identification of patients with HPA axis dysfunction following trans-sphenoidal pituitary surgery is important. Our centre measures post-operative day 5 0900 h serum cortisol (24 h after the last dose of glucocorticoid) to identify the need for glucocorticoid replacement. This is given if post-operative day 5 0900 h cortisol concentration is <300 nmol/l, until dynamic pituitary function assessment occurs.Methods: Data were reviewe...

Background: Phaeochromocytomas (PCC) and paragangliomas (PGL) are neuroendocrine tumours that can secrete catecholamines. PCC are found in the adrenals, whereas PGL are found at any level between the skull base to the pelvis. More than 25% of cases are associated with mutations in susceptibility genes such as the SDH subunits. Screening for PCC/PGL crucially depends on detection of biochemical markers such as catecholamines and metanephrines (catecholamine metabolites).<p ...

Nelson’s syndrome (NS) is a potentially severe complication following bilateral adrenalectomy for Cushing’s disease (CD). Series assessing outcomes of treatments for NS are limited by small sample size, often short follow-up and variability of success criteria. We performed a UK multi-centre study aiming to review outcomes of primary treatment for NS. Clinical, laboratory, imaging data were collected. Kaplan-Meier method, log-rank test, Cox regression analysis were u...
