10 Professor Jerome W. Conn, M.D., Sc.D. University of Michigen
11 Primary hyperaldosteronism (first documented case) apr.: 34 years old female. mild hypertension, hypokalaemia, hypernatraemic alkalosis, sustained renal function 1954 dec.: exploratory laparotomy: rigth adrenalectomy 1955: case report (J Lab Clin Med 45:661, 1955)
12
13 Prevalence suggested by Conn JAMA 190:220 (1964) I suggest....that as many as 20% of patients with so-called essential hypertension might be suffering from primary aldosteronism while still maintaining normal levels of serum electrolytes.
14 Prevalence suggested by Kaplan Clinical Hypertension textbook 5. ed. (1990) Primary aldosteronism [] has generated as many publications as the number of patients found to have it.
15 Prevalence of hyperaldosteronism Reality: 5-10% Fardella CE, et al. J. Clin Endocrinol Metab Lim PO, et al. J Hum Hypertens : Mosso L, et al. Hypertension : Rossi GP, & PAPY Study Investigators.

17 Primary hyperaldosteronism
18 Symptoms In 100% of the patients Hypertension Suppressed plasma renin activity Elevated plasma aldosteron levels in less than 50% Paraesthesia Seeing disorder Intermitting muscle paralysis Tetany In 50 90% Headaches Hypokalaemia/hypernatraemia Muscle weakness/tiredness Arrthymias, Polyuria/polydipsia Impaired glucose tolerancy Alkalosis
19 Suspect for primary hyperaldosteronism Hypertension and hypokalaemia Therapy resistant hypertension (3 or more antihypertensive drug combination with maximal dose) Adrenal incidentaloma and hypertension Anamnesis Young age (under 20 y), stroke under 40 years Severe hypertension (>160/100 mm Hg)
20 Screening Aldosteron-renin ratio (ARR) Standardized sample collection (morning, 15 min rest, normokalaemia) Drug interactions ACE-I, duretics, hypokalaemia: decrease beta-blockers, central alpha2 agonists: increase Funder J, et. al. J Clin Endocrinol Metab 2008, 93(9):
21 Evaluation of ARR Can not be assessed spironolacton eplerenon amilorid False positive results Beta blockers Alpha-methyldopa Clonidin NSAIDs False negative results ACE-inhibitors ARBs Other diuretics Dihidropiridin calciumchannel blockers Estrogenes
22 Correct evaluation For 6 weeks spironolactone eplerenone amilorid Estrogenes Do not need to Doxazosin Prazosin Verapamil Hidralazin For 2 weeks ACE-inhibitors ARBs Diuretics Dihidropiridin calcium-channel inhibitors Beta blockers Alpha-methyldopa Clonidin NSAIDs
