Bolus, bolus along with continuous infusion or continuous infusion of ACTH did not affect both indices.The absence of clinical success (i.e. unchanged or increased blood pressure) was 33% and absence of biochemical success (persistent hypokalaemia or persistently raised aldosterone-to-renin ratio, or both) was 15%.
Retrospective data confirm the efficacy of ACTH or the synthetic analogue Synacthen in the treatment of acute gout in patients with comorbidities such as cardiovascular disease, chronic kidney disease, and hypertension, including those who were hospitalised, with all patients responding after 1-3 doses.
Adrenocorticotropic hormone (ACTH)-secreting tumors account for 2% to 6% of adenomas and are associated with obesity, hypertension, diabetes, and other morbidity.
The consequent cortisol deficiency results in a compensatory increase in adrenocorticotropic hormone (ACTH) drive, which stimulates the production of deoxycorticosterone and corticosterone leading to hypertension and hypokalaemia.
These findings expand on the clinical spectrum of phenotypes associated with KCNJ5 mutations and implicate these mutations in the pathogenesis of hypertension associated with increased aldosterone response to ACTH stimulation.
Specific mutations in the leptin and the melaninocortin receptor genes in animal models of obesity without hypertension, the actions of α-melanocyte stimulating hormone, and SNS activity in obesity-related hypertension may promote recognition of protective and promoting factors for hypertension in obesity.
This group had no difference in basal ACTH/renin (REN) concentrations compared with controls and the 83 patients with hypertension (73%) without an ALD hyper-response to ACTH stimulation.
Overall, the data establish that the alpha(2)-Na(+)-K(+)-ATPase ouabain-binding site is of central importance in the development of ACTH-induced hypertension.
These novel data support the suggestion that chronic aldosterone excess, in genetically susceptible individuals, may be a consequence of increased ACTH drive to the adrenal and identify novel molecular mechanisms that may lead to the development of hypertension within the general population.
Overall, the data establish that the alpha(2)-Na(+)-K(+)-ATPase ouabain-binding site is of central importance in the development of ACTH-induced hypertension.
