  2. Cushing's syndrome (veterinary) - Wikipedia

    en.wikipedia.org/wiki/Cushing's_syndrome...

    A study of 66 dogs with Cushing's found 91% of dogs to have either polyuria or polydipsia, 79% to have polyphagia, and 77% to have alopecia. [4] Signs of ectopic adrenocorticotropic hormone secretion that accompany the rapidly progressing physical changes are high plasma levels of adrenocorticotropic hormones and cortisol alongside hypokalaemia ...

    Other cases are caused by various disease processes, [8] [9] [10] including failure of the pituitary gland to secrete ACTH, the hormone which stimulates the adrenal production of cortisol. [5] Hypoadrenocorticism is more frequent in dogs than in humans; in fact, it may occur one hundred times more often in the canine population.

    An ACTH stimulation test involving administration of corticotropin-releasing hormone (CRH) or another agent can differentiate this condition from ectopic ACTH secretion. In a patient with Cushing's disease, the tumor cells will be stimulated to release corticotropin and elevated plasma corticotropin levels will be detected. [8]

  5. Hypersomatotropism (veterinary) - Wikipedia

    Dogs with primary hypothyroidism also have increased levels of growth hormone and IGF-1; however, thyroxine and thyroid stimulating hormone levels are normal in dogs with hypersomatotropism. [1] Progestogens administered to dogs may result in endogenous adrenocorticotropic hormone secretion being suppressed, which lowers the cortisol ...

  6. Adrenocorticotropic hormone - Wikipedia

    en.wikipedia.org/wiki/Adrenocorticotropic_hormone

    Adrenocorticotropic hormone (ACTH; also adrenocorticotropin, corticotropin) is a polypeptide tropic hormone produced by and secreted by the anterior pituitary gland. [1] It is also used as a medication and diagnostic agent .

  7. ACTH stimulation test - Wikipedia

    en.wikipedia.org/wiki/ACTH_stimulation_test

    The ACTH test (also called the cosyntropin, tetracosactide, or Synacthen test) is a medical test usually requested and interpreted by endocrinologists to assess the functioning of the adrenal glands' stress response by measuring the adrenal response to adrenocorticotropic hormone (ACTH; corticotropin) or another corticotropic agent such as tetracosactide (cosyntropin, tetracosactrin; Synacthen ...

  8. Adrenocortical hormone - Wikipedia

    en.wikipedia.org/wiki/Adrenocortical_hormone

    Secretion is typically regulated by the hypothalamus which secretes corticotropin-releasing hormone (CRH) to the pituitary gland, stimulating the pituitary to secrete adrenocorticotropic hormone (ACTH). ACTH then travels to the adrenal glands and induces the release of cortisol into the bloodstream. [7] In Cushing's syndrome, this process ...

    That is, in the beginning, 17,20-lyase deficiency will block synthesis of sex steroid hormones, forcing the pathways to produce more cortisol. However, the initial excess of cortisol is rapidly corrected by negative feedback mechanism—high cortisol decreases secretion of adrenocorticotropic hormone (ACTH) from zona fasciculata of adrenal gland.
