Introduction: Hypertension is common in patients with Turner Syndrome (TS), and they appear to have an increased predisposition with various proposed disease related factors; sex hormone imbalance, aortopathy, increased activation of the renin-angiotensin-aldosterone system, insulin resistance, growth hormone deficiency/resistance, adverse imprinting during fetal life and renal malformations. Despite high susceptibility and unique challenges in managing hypertension in this gr...

Introduction: Cardiovascular disease is the commonest cause of death (absolute-excess-risk:41%) in Turner Syndrome (TS). Hypertension is a major risk for circulatory-disease (up to 60%) and a key modifiable-risk factor of aortopathy, ischemic heart disease and stroke in TS. There is no current consensus for hypertension diagnosis/management in TS.Methods: Retrospective multi-centre observational study of patients aged &#...

Background: Congenital Adrenal Hyperplasia (CAH) requires exogenous steroid replacement and can be monitored with 17-OH Progesterone and Androstenedione. We reviewed real world data to evaluate these markers in relation to hydrocortisone dose in patients treated in 21 centres throughout 14 countries.Method: Retrospective cohort study using pseudonymised data from patients with 21α-Hydroxylase Deficiency recorded in the International Congenital Adren...

Introduction: Disorders of Sex Development (DSD) can be associated with an increased risk of germ cell tumours depending on the underlying diagnosis. To date however knowledge regarding the indications and timing of gonadectomy is lacking.Methods: The I-DSD Registry was interrogated for anonymised information regarding the diagnosis, karyotype, sex of rearing and timing of gonadectomy, if undertaken, of all individuals of any karyotype who were over the ...

Background: In 2019, the International CAH Registry (I-CAH) performed a benchmarking exercise of acute adrenal insufficiency related adverse events including adrenal crises (AC) and sick day episodes (SDE).Methods: In 2022, I-CAH data on children aged <18 years at first visit with 21-hydroxylase deficiency CAH from 35 centres in 19 countries were analysed to examine the current occurrence of SDE and AC and compared t...

Background: The reported occurrence and management of acute adrenal insufficiency–related adverse events in children vary widely between centres and may depend on available resources.Methods: Real world data from the I-CAH Registry from 44 centres [32 from high income (HIC) and 12 from low/middle income (LMIC) countries] and a total number of 607 children were linked to the results of a health care survey of local r...

Background: The reported occurrence and management of acute adrenal insufficiency–related adverse events in children vary widely between centres and may depend on available resources.Methods: Real world data from the I-CAH Registry that included a total of 2478 patient years follow-up on 607 children from 44 centres were studied and their association to the results of a health care survey of these centres that enqui...
