Case: A 32 year old with known classical 21 hydroxylase deficiency was planning her first pregnancy. She had a history of clitoral reduction and vaginal reconstructive surgery as a baby. Pre-conception control on prednisone and fludrocortisone was good: 17(OH) progesterone 8.3 nmol/l, androstenedione 9.8 nmol/l (0.7–10.8), testosterone 3.0 nmol/l (0.2–3).

Background: The UK Acromegaly Register contains data for 2700 patients. IGF-1 and random growth hormone (GH) measurements are used for disease monitoring. The registry reference laboratory (RRL) uses the Immunodiagnostic systems (IDS)-iSYS immunoassay platform for GH and IGF-1. The RRL uses age- and sex-specific reference ranges for IGF-1. We compared IGF-1 and GH results fromlocal laboratories to those of the RRL (pre-defined as the Gold standard) to determine the extent of d...

Introduction: Although acromegaly and pituitary gigantism have the same pathological cause, they have different disease characteristics.Aim: To study tumour size, treatment course and the most common comorbidities in a population with young-onset acromegaly.Materials and Methods: UK Acromegaly Register (UKAR, 22 centres, 1997-2017) retrospective analysis, enriched with patients from the FIPA-consortium. We defined gigantism as diag...

It is unclear whether this is associated with increased mortality and morbidity compared to patients with concordant normal results.Methodology: A retrospective study was conducted on the United Kingdom Acromegaly Registry (UKAR). A comparison of mortality and morbidity was performed among four groups categoris...
