Central precocious puberty (CPP) is a common and well-recognised condition characterised by premature activation of the hypothalamic-pituitary-gonadal axis, with consequent potential adverse health and psychosocial outcomes. Standard management of CPP is with periodic injections of gonadotropin-releasing hormone analogue therapy. Decapeptyl SR (Triptorelin pamoate) has for several years been available as a long-acting (12-weekly, 11.25 mg) preparation, but more recently is ava...

Hyperthyroidism has been linked to long-term cardiovascular and metabolic morbidity and increased mortality. We aimed to assess differences in mortality and cardiometabolic outcomes depending on treatment modality to better inform patient-clinician decision-making.Methods: We identified 62,474 patients with newly diagnosed hyperthyroidism, treated with antithyroid drugs (ATD), radioiodine or thyroidectomy from a UK population-based GP database (>16M ...

Introduction: Corticotropin-releasing factor type 1 (CRF1) receptor antagonists, such as crinecerfont, have recently been investigated for the treatment of classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD), a rare autosomal disease characterized by cortisol deficiency, elevated adrenocorticotropic hormone (ACTH), and excess androgen production. In a study of adults with 21OHD, treatment with crinecerfont for 14 days led to median ...

Introduction: 24-hydroxylase, encoded by a CYP24A1 gene, is a crucial enzyme entailed in catabolism of vitamin D. Loss-of-function mutations of CYP24A1 result in hypercalcemia, not adequately concomitant high levels of 1,25(OH)2D and low PTH levels. The variety of clinical manifestations depends on age – mutations can lead to fatal infantile hypercalcemia among neonates (typically precipitated by supplementation of vitamin D), whereas adults’ symptoms are usually mil...

Background: Combinatory treatments with analogues of incretins might mimic the beneficial effects of bariatric surgery. We could show in the past that a combinatory treatment with PYY 3-36 and liraglutide leads to a similar body weight loss as Roux-en-Y gastric bypass (RYGB). We hypothesize that a combination of semaglutide and a modified PYY 3-36 analogue with increased selectivity for the neuropeptide Y receptor type 2 (NNC0165-1273) exceeds the weight-reducing effects of ba...

Background: Adamantinomatous craniopharyngiomas (CP) are rare malformational tumors. The association between age at diagnosis and the outcome, clinical presentation and treatment of pediatric CP patients is not clear. The aim of this cohort study was to determine clinical presentation, outcome and quality of life in CP patients diagnosed at different AaD. Methods: Seven hundred and twenty-two patients diagnosed with CP were recruited 1999-2021 in HIT-End...

Introduction: The differential diagnosis between arginine vasopressin deficiency (AVP-D), formally known as central diabetes insipidus, and primary polydipsia (PP) is challenging. In clinical routine, psychopathologic findings are often used as a hallmark for diagnosing PP; thus, it is often referred to as psychogenic polydipsia. Yet, psychopathologic characteristics are barely assessed in patients with AVP-D, and to date, no data exist comparing AVP-D and PP with regard to th...

Background: Cushing’s disease is the most common cause of endogenous Cushing’s syndrome in adults, affecting females>males (ratio 3:1). In suspected cases, careful clinical assessment is required to ascertain a pre-test probability. This is followed by robust biochemical testing, which guides further management.One-week test protocol: Congruent biochemical tests are conducted over a one-week period in an outpatient setting. Patients attend on d...

Background: Primary hypothyroidism affects about 3% of the general population (5.1% women and 0.9% men). The majority of people are treated adequately with levothyroxine. However about 5–10% of hypothyroid patients (representing between 75 000 and 150 000 adults in the UK) continue to experience profound and sometimes disabling symptoms, such as fatigue/depression/impaired cognition, in spite of being adequately replaced biochemically. Before any trial of alternatives to ...

The effect of subclinical hypothyroidism (SH) and thyroid autoimmunity on adverse pregnancy and neonatal outcome, are still subject of interest and controversy. Nowadays, guidelines recommend establishing reference values of local thyroid hormones that allow definition of the SH in a specific population. The objective of this study was to assess the effect of SH and autoimmunity in early pregnancy on adverse pregnancy and neonatal outcome in our population. The reference range...
