Hypertension in Cushing’s Syndrome: From Pathogenesis to Treatment

Cicala, Maria Verena, Mantero, Franco·2010·Neuroendocrinology

Abstract

Hypertension is one of the most distinguishing features of endogenous Cushing’s syndrome (CS), as it is present in about 80% of adult patients whereas in children its prevalence is about 47%. Hypertension in CS is significantly correlated with the duration of hypercortisolism and results from the interplay between several pathophysiological mechanisms regulating plasma volume, peripheral vascular resistance and cardiac output, all of which are increased in this state. Glucocorticoids cause hypertension through several mechanisms: their intrinsic mineralocorticoid activity; through activation of the renin-angiotensin system; by enhancement of vasoactive substances, and by causing suppression of the vasodilatory systems. In addition, glucocorticoids may exert some hypertensive effects on cardiovascular regulation through the CNS via both glucocorticoid and mineralocorticoid receptors. Hypertension in CS usually resolves with surgical removal of the tumor, but some patients require pharmacological antihypertensive treatment both pre- and postoperatively. Thiazides and furosemide should be avoided, while adrenergic blockade and calcium channel antagonists are usually ineffective. Mineralocorticoid receptor antagonists, Ang II blockers and ACE inhibitors are good anti-hypertensive options; PPAR-γ agonists may help in many aspects of the insulin resistance syndrome. The relatively selective glucocorticoid receptor antagonist Mifepristone (RU 486) could reduce blood pressure in patients with CS. Neuromodulatory agents such as the serotonin inhibitors cyproheptadine and ritanserin, valproid acid, dopamine agonists, somatostatin analogs may occasionally be effective, as well as drugs acting directly at the adrenal levels, such as Ketoconazole and aminoglutetimide or even opDDD. Treating hypertension in CS remains a difficult task and a big challenge, in order to decrease the morbidity and mortality associated with the disease.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Although small cohort studies suggest high BP is highly prevalent (often exceeding 80%) among patients with Cushing syndrome, the overall frequency of hypertension among patients with Cushing syndrome remains to be accurately characterized.

    “Although a variety of relatively small cohort studies suggest that high BP is highly prevalent (often exceeding 80%),324,325 the overall frequency of hypertension, mild or severe, among patients with Cushing syndrome remains to be accurately characterized.”
  • Hypercortisolism can promote hypertension through additional pathways including activating the renin-angiotensin system, sensitizing the vasculature to catecholamines, and impairing endogenous nitric oxide bioavailability.

    “However, it is also recognized the hypercortisolism can promote hypertension through a variety of additional pathways (eg, activating the renin-angiotensin system, sensitizing the vasculature to catecholamines, and impairing endogenous nitric oxide bioavailability).324,325”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
