    In Cushing's disease, ACTH responses to CRH were similar before octreotide (9.9 +/- 1.7 to 19.4 +/- 6.1 pmol/L) and after it (8.8 +/- 2.4 to 19.1 +/- 8.2 pmol/L).

    Summary
    In 5 patients with Cushing's disease the plasma ACTH and cortisol responses to CRH were similar both before (ACTH from 9.9 +/- 1.7 pmol/L to 19.4 +/- 6.1 pmol/L; cortisol from 496 +/- 43.9 nmol/L to 923 +/- 355 nmol/L) and after octreotide injection (ACTH from 8.8 +/- 2.4 pmol/L to 19.1 +/- 8.2 pmol…

    Summary · context
    In this study we investigated the effects of somatostatin or octreotide on ACTH levels of patients with corticotropin hypersecretion: 7 patients with Addison's disease, 2 patients previously adrenalectomized for Cushing's disease, 4 patients with Cushing's disease and 3 patients with ectopic ACTH syndrome.
    Summary · context
    Plasma ACTH and cortisol levels were determined after somatostatin (500 micrograms over 60 min) infusion or octreotide (100 micrograms sc) injection.
