Apparent Mineralocorticoid Excess

  • For example, congestive heart failure or cirrhosis of the liver can cause an effective decrease in blood pressure, and narrowing of a renal artery can cause a reduction in the flow of blood to a kidney.[britannica.com]
Episodic Weakness
  • Symptoms and Signs Symptoms are similar to those of primary aldosteronism and include hypokalemic alkalosis that causes episodic weakness, paresthesias, transient paralysis, and tetany. In many cases, the only manifestation is hypertension.[msdmanuals.com]

  • Weight gain, glucose intolerance, striae, skin thinning, increase in cervical, supraclavicular fat pad, facial plethora, muscle weakness, or osteoporosis in an obese patient.[thecurbsiders.com]
Medication Noncompliance
  • Pseudo-resistant HTN: BP uncontrolled due to medication noncompliance, inadequate dosing, poor choice of agents, etc.[thecurbsiders.com]
Blurred Vision
  • The common signs and symptoms associated with Secondary Hyperaldosteronism include : Numbness Fatigue Hypokalemia - abnormally low levels of potassium in blood Blurred vision High blood pressure (that does not decrease in response to medication) Paralysis[dovemed.com]
Papilledema
  • BACKGROUND: Idiopathic intracranial hypertension (IIH) is a syndrome consisting of headache, visual field defects and papilledema of uncertain etiology.[ncbi.nlm.nih.gov]

Workup

  • Workup may continue here with dexamethasone suppression test. Final Note The physiologic opposite of hypermineralocorticoidism is type IV (distal) renal tubular acidosis.[medicalmediareview.com]

Treatment

  • Treatment Treament of cause Sometimes aldosterone antagonists Treatment involves correcting the cause.[merckmanuals.com]
  • Make the best clinical decisions with an enhanced emphasis on evidence-based practice and expert opinions on treatment strategies. Zero in on the most relevant and useful references with the aid of a more focused, concise bibliography.[books.google.com]
  • Treament of cause Sometimes aldosterone antagonists Treatment involves correcting the cause.[msdmanuals.com]
  • Rapidly consult with trusted authorities thanks to new expert-opinion treatment strategies and recommendations. Zero in on the most relevant and useful references with the aid of a more focused, concise bibliography.[books.google.com]
  • Outlook (Prognosis) The outlook for primary hyperaldosteronism is good with early diagnosis and treatment. The outlook for secondary hyperaldosteronism depends on the cause of the condition.[account.allinahealth.org]

Prognosis

  • Outlook (Prognosis) The outlook for primary hyperaldosteronism is good with early diagnosis and treatment. The outlook for secondary hyperaldosteronism depends on the cause of the condition.[account.allinahealth.org]
  • HYPERALDOSTERONISM PROGNOSIS The prognosis of patients drastically improves once the tumor is removed.[medicalook.com]
  • When primary aldosteronism is caused by a solitary adenoma, the prognosis is good. Once this tumor is removed, blood pressure will drop, and 70% of these patients have full remission.[encyclopedia.com]

Etiology

  • BACKGROUND: Idiopathic intracranial hypertension (IIH) is a syndrome consisting of headache, visual field defects and papilledema of uncertain etiology.[ncbi.nlm.nih.gov]
  • […] without renin secretion. leads to sodium and water retention and potassium excretion (HTN and alkalosis) is one of the leading cause of secondary HTN more common in women. the volume leads to renin secretion (and angiotensin II) helpful in diagnosis etiology[quizlet.com]
  • The most common etiologic factors are adrenal adenoma, idiopathic hyperplasia of the adrenal cortex, and occasionally carcinoma of the adrenal gland.[medical-dictionary.thefreedictionary.com]
  • Etiology. The diseases which are followed by sharp renal ischemia (an idiopathic hypertensia, a renal hypertension) can be the cause of a secondary aldosteronism.[infomeds.net]
  • (Etiology) Secondary Hyperaldosteronism is typically caused by a reduced blood flow to the kidneys leading to excess aldosterone production.[dovemed.com]

Epidemiology

  • Epidemiology References: [1] [2] [3] Epidemiological data refers to the US, unless otherwise specified.[amboss.com]
  • Epidemiology: The age of onset of hypertension is an important piece of information to help decipher between the different ideologies of primary hyperaldosteronism (Funder et al., 2008).[wikilectures.eu]
  • Epidemiology Many decades ago the prevalence of primary aldosteronism as a cause of hypertension was thought to be very low - figures like 0.5%-2% had been quoted. [ 1 , 2 ] However, it has subsequently emerged that these low prevalence rates were simply[patient.info]

Pathophysiology

  • To explain the pathophysiology, we have hypothesized an abnormal function of ang II receptor signal transduction which excessively stimulates PLA2, resulting in overproduction of PG synthesis in tissues.[ncbi.nlm.nih.gov]
  • This implies that in these complex conditions, successful therapy should address the disorder in aldosterone and also the other underlying pathophysiologic mechanisms.[ncbi.nlm.nih.gov]

  • Secondary hyperaldosteronism Secondary aldosteronism is defined as any pathophysiology that results in an up regulation of the renin angiotensin aldosterone feedback system (McCance, Huether, Brashers, & Rote, 2010).[wikilectures.eu]
