An attempt has been made to modify the Sayers method for the assay of corticotrophin by substituting for hypophysectomy an injection of sufficient hydrocortisone acetate to suppress the release of endogenous pituitary corticotrophin in intact rats over the period of the assay. The results of forty such assays of subcutaneous corticotrophin seem to indicate that this procedure is about 1(1/2) to 2 times as efficient as the original method using hypophysectomized rats. For a 2 + 2 point assay it was necessary to use a minimum of twenty-four to thirty-two rats.

Purpose: To evaluate the effect of osilodrostat and hypercortisolism control on blood pressure (BP) and glycemic control in patients with Cushing's disease.
Methods: Pooled analysis of two Phase III osilodrostat studies (LINC 3 and LINC 4), both comprising a 48-week core phase and an optional open-label extension. Changes from baseline in systolic and diastolic BP (SBP and DBP), fasting plasma glucose (FPG), and glycated hemoglobin (HbA) were evaluated during osilodrostat treatment in patients with/without hypertension or diabetes at baseline.

Introduction: Infantile Epileptic Spasms Syndrome (IESS) typically has a profound impact on the neurodevelopment of patients. The study on IESS indicates possible geographical variation in etiology and a lack of data from China. Our study intends to summarize the etiology of IESS and analyze its characteristics.

Cushing syndrome (CS) is a constellation of signs and symptoms caused by excessive exposure to exogenous or endogenous glucocorticoid hormones. Endogenous CS is caused by increased cortisol production by one or both adrenal glands (adrenal CS) or by elevated adrenocorticotropic hormone (ACTH) secretion from a pituitary tumour (Cushing disease (CD)) or non-pituitary tumour (ectopic ACTH secretion), which stimulates excessive cortisol production. CS is associated with severe multisystem morbidity, including impaired cardiovascular and metabolic function, infections and neuropsychiatric disorders, which notably reduce quality of life.

Introduction Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder primarily caused by 21-hydroxylase enzyme deficiency, impairing cortisol synthesis and resulting in elevated androgen levels. CAH presents in two classical forms: salt-wasting (SW) and simple virilizing (SV). Although CAH is rare in India, regional variations and the absence of a national newborn screening (NBS) program pose significant challenges to accurate diagnosis.
