If there is primary hyperaldosteronism, the decreased renin (and subsequent decreased angiotensin II) will not lead to a decrease in aldosterone levels (a very helpful clinical tool in diagnosis of primary hyperaldosteronism). Diagnosis
Screening may be considered in people with high blood pressure presenting with low blood potassium, high blood pressure that is difficult to treat, other family members with the same condition, or a mass on the adrenal gland.Measuring aldosterone alone is not considered adequate to diagnose primary hyperaldosteronism. Rather, both renin and aldosterone are measured, and a resultant aldosterone-to-renin ratio (ARR) is used for case detection. A high aldosterone-to-renin ratio suggests the presence of primary hyperaldosteronism. The diagnosis is made by performing a saline suppression test, ambulatory salt loading test, or fludrocortisone suppression test.Measuring sodium and potassium concentrations simultaneously in serum and urine specimens has been suggested for screening purposes. Calculating the serum sodium over urinary sodium to serum potassium over urinary potassium (SUSPUP) and the (serum sodium to urinary sodium to (serum potassium)2 (SUSPPUP) ratios delivers calculated structure parameters of the RAAS, which may be used as a static function test. Its results have to be confirmed by calculating the ARR.If primary hyperaldosteronism is confirmed biochemically, CT scanning or other cross-sectional imaging can confirm the presence of an adrenal abnormality, possibly an adrenal cortical adenoma (aldosteronoma), adrenal carcinoma, bilateral adrenal hyperplasia, or other less common changes. Imaging findings may ultimately lead to other necessary diagnostic studies, such as adrenal venous sampling, to clarify the cause.
With its antiandrogen effect, spironolactone drug therapy may have a range of side effects in males and females, including gynecomastia and irregular menses. These symptoms occur less frequently with eplerenone drug therapy.In the absence of treatment, individuals with hyperaldosteronism often have poorly controlled high blood pressure, which may be associated with increased rates of stroke, heart disease, and kidney failure. With appropriate treatment, the prognosis is considered good.Esaxerenone, the first non-steroidal mineralocorticoid blocker, was approved in 2019 in Japan to treat essential hypertension. Finerenone, a drug belonging to the same class, reached phase 3 clinical trial in 2020, but is not yet considered for hypertension. More importantly, next-generation Aldosterone Synthase Inhibitors have entered the research pipeline with CIN-107 undergoing Phase 2 clinical trial as of 2021

Society and culture
The Primary Aldosteronism Foundation is a patient-driven initiative committed to creating the paradigm shift that will lead to optimum diagnosis and treatment of primary aldosteronism by raising awareness, fostering research, and providing support to patients and healthcare professionals worldwide. Eponym
Conns syndrome is named after Jerome W. Conn (1907–1994), the American endocrinologist who first described the condition at the University of Michigan in 1955. References
