A congenital or acquired condition of insufficient production of ALDOSTERONE by the ADRENAL CORTEX leading to diminished aldosterone-mediated synthesis of Na(+)-K(+)-EXCHANGING ATPASE in renal tubular cells. Clinical symptoms include HYPERKALEMIA, sodium-wasting, HYPOTENSION, and sometimes metabolic ACIDOSIS.
Abnormally high potassium concentration in the blood, most often due to defective renal excretion. It is characterized clinically by electrocardiographic abnormalities (elevated T waves and depressed P waves, and eventually by atrial asystole). In severe cases, weakness and flaccid paralysis may occur. (Dorland, 27th ed)
A synthetic mineralocorticoid with anti-inflammatory activity.
A hormone secreted by the ADRENAL CORTEX that regulates electrolyte and water balance by increasing the renal retention of sodium and the excretion of potassium.
A highly specific (Leu-Leu) endopeptidase that generates ANGIOTENSIN I from its precursor ANGIOTENSINOGEN, leading to a cascade of reactions which elevate BLOOD PRESSURE and increase sodium retention by the kidney in the RENIN-ANGIOTENSIN SYSTEM. The enzyme was formerly listed as EC 3.4.99.19.
Conditions in which the production of adrenal CORTICOSTEROIDS falls below the requirement of the body. Adrenal insufficiency can be caused by defects in the ADRENAL GLANDS, the PITUITARY GLAND, or the HYPOTHALAMUS.
A group of inherited disorders of the ADRENAL GLANDS, caused by enzyme defects in the synthesis of cortisol (HYDROCORTISONE) and/or ALDOSTERONE leading to accumulation of precursors for ANDROGENS. Depending on the hormone imbalance, congenital adrenal hyperplasia can be classified as salt-wasting, hypertensive, virilizing, or feminizing. Defects in STEROID 21-HYDROXYLASE; STEROID 11-BETA-HYDROXYLASE; STEROID 17-ALPHA-HYDROXYLASE; 3-beta-hydroxysteroid dehydrogenase (3-HYDROXYSTEROID DEHYDROGENASES); TESTOSTERONE 5-ALPHA-REDUCTASE; or steroidogenic acute regulatory protein; among others, underlie these disorders.
An adrenal disease characterized by the progressive destruction of the ADRENAL CORTEX, resulting in insufficient production of ALDOSTERONE and HYDROCORTISONE. Clinical symptoms include ANOREXIA; NAUSEA; WEIGHT LOSS; MUSCLE WEAKNESS; and HYPERPIGMENTATION of the SKIN due to increase in circulating levels of ACTH precursor hormone which stimulates MELANOCYTES.

Disseminated Langerhans' cell histiocytosis and massive protein-losing enteropathy. (1/22)

Symptomatic involvement of the gastrointestinal (GI) tract as a prominent symptom in Langerhans' cell histiocytosis (LCH) is uncommon, occurring in less than 1 to 5% of all cases, even when the disease is in its disseminated form. Up to now, there have been reports of 18 cases of LCH with GI manifestations, including our 2 cases, with diarrhea (77.7%), protein-losing enteropathy (33.3%) and bloody stool being the most frequent findings. The authors present two patients with severe diarrhea and refractory hypoalbuminemia, and with the protein-losing enteropathy documented by Cr51-labeled albumin studies. A review of the literature indicated that the presence of GI symptoms is often associated with systemic disease as well as with poor prognosis, mainly under 2 years of age. Radioisotopes are useful for documenting protein loss in several diseases with high specificity and sensitivity, and their utilization in the cases reviewed here permitted diagnoses in 6 children, as well as improved therapeutic management.  (+info)

Functional expression of a pseudohypoaldosteronism type I mutated epithelial Na+ channel lacking the pore-forming region of its alpha subunit. (2/22)

The autosomal recessive form of type I pseudohypoaldosteronism (PHA-I) is an inherited salt-losing syndrome resulting from diminution-of-function mutations in the 3 subunits of the epithelial Na+ channel (ENaC). A PHA-I stop mutation (alpha(R508stop)) of the ENaC alpha subunit is predicted to lack the second transmembrane domain and the intracellular COOH-terminus, regions of the protein involved in pore function. Nonetheless, we observed a measurable Na+ current in Xenopus laevis oocytes that coexpress the beta and gamma subunits with the truncated alpha subunit. The mutant alpha was coassembled with beta and gamma subunits and was present at the cell surface at a lower density, consistent with the lower Na+ current seen in oocytes with the truncated alpha subunit. The single-channel Na+ conductance for the mutant channel was only slightly decreased, and the appearance of the macroscopic currents was delayed by 48 hours with respect to wild-type. Our data suggest novel roles for the alpha subunit in the assembly and targeting of an active channel to the cell surface, and suggest that channel pores consisting of only the beta and gamma subunits can provide significant residual activity. This activity may be sufficient to explain the absence of a severe pulmonary phenotype in patients with PHA-I.  (+info)

Prerenal azotemia in a diabetic patient with hyporeninemic hypoaldosteronism and autonomic neuropathy. (3/22)

Patients with hyporeninemic hypoaldosteronism show mild to moderate renal insufficiency, with a creatinine clearance of 20-75 ml/min, and asymptomatic hyperkalemia. A low degree of sodium wasting and mild hyperchloremic metabolic acidosis are also usually present. However, severe sodium wasting and volume depletion are not typically seen unless the patient is placed on severe sodium restriction or has some other cause of extrarenal sodium loss. In fact, acute renal failure has not been reported in such patients. We describe a diabetic patient with hyporeninemic hypoaldosteronism and autonomic neuropathy who developed recurrent episodes of acute renal failure due to prerenal azotemia during acute exacerbations of diarrhoea. In our case, despite significant hypovolemia, the renin-aldosterone axis was markedly suppressed, implying that sympathetic tone played a decisive role in renin regulation.  (+info)

Isolated adrenocorticotropin deficiency presenting with impaired renin-angiotensin-aldosterone system and suppressed parathyroid hormone-vitamin D axis. (4/22)

We report here a 47-year-old woman with isolated adrenocorticotropin (ACTH) deficiency (IAD). She presented impaired renin-angiotensin-aldosterone (R-A-A) system and suppressed parathyroid hormone (PTH)-vitamin D system. She showed severe hyponatremia due to secondary adrenocortical insufficiency, which was deteriorated by hypoaldosteronism. She also showed hyperphosphatemia and relative hypercalcemia with suppressed PTH-vitamin D axis. Moreover, she showed hypothyroidism, which was thought to be important to maintain normal Ca levels under secondary hypoadrenalism via decrease in bone resorption by T3. Replacement with glucocorticoid completely normalized PTH-vitamin D axis and R-A-A system. Thus, the present case implicates that severe adrenocortical deficiency due to IAD might affect both R-A-A system and PTH-vitamin D axis. These findings suggest that the ACTH-cortisol axis has an important role in mineral metabolism in vivo.  (+info)

Pseudo-hypo aldosteronism Type II. (5/22)

A 50-day-old infant diagnosed as meningitis had persistently elevated serum potassium, low serum bicarbonate and normal serum sodium. She had metabolic acidosis with low TTKG, low serum renin and low normal serum aldosterone with no renal failure or extra renal causes of hyperkalemia. Hence a diagnosis of Type II pseudo-hypoaldosteronism was made. She was started on oral thiazide following which her serum electrolytes normalized.  (+info)

Treating proteinuria in a diabetic patient despite hyperkalaemia due to hyporeninaemic hypoaldosteronism. (6/22)

Diabetes mellitus is a common cause of hyporeninaemic hypoaldosteronism that might result in significant hyperkalaemia. We describe a patient with diabetic nephropathy and proteinuria who developed a remarkable hyperkalaemia on treatment with an angiotensin-receptor blocker. The management of hyperkalaemia and the pathophysiological background of hyporeninaemic hypoaldosteronism are discussed.  (+info)

Successful treatment of chyluria, glomerular and tubular abnormalities in a young lady with silver nitrate instillation. (7/22)

A 21- year-old lady presented with chyluria, severe malnutrition, secondary amenorrhea, profound hypoalbuminemia, heavy proteinuria and renal tubular abnormalities suggestive of Type IV renal tubular acidosis. No particular cause for chyluria could be ascertained. She was successfully treated with an injection of 2% silver nitrate into the left ureter and urinary bladder. She continues to be well after 15 years of follow-up.  (+info)

Pseudohypoaldosteronism: case report and discussion of the syndrome. (8/22)

A 41-year-old man, complaining of leg cramps, was found to have persistent hyperkalemia. Except for mild hypertension, his physical examination and laboratory values to exclude connective tissue diseases and diabetes mellitus were normal. Renal function testing revealed a normal glomerular filtration rate and tubular capacity to acidify and dilute, as well as near-normal ability to concentrate his urine. Hormonal evaluation revealed a normal cortisol, as well as normal resting and stimulated renin and aldosterone levels. A selective defect in tubular potassium secretion was demonstrated. In the absence of aldosterone deficiency or renal dysfunction, it was assumed that the patient had primary renal resistance to aldosterone, known as pseudohypoaldosteronism. Treatment with hydrochlorothiazide controlled his hyperkalemia and hypertension. His case emphasizes the diagnostic and therapeutic factors that should be considered in evaluating and treating a non-hospitalized patient with sustained hyperkalemia.  (+info)

Hypoaldosteronism is a medical condition characterized by decreased levels or impaired function of the hormone aldosterone, which is produced by the adrenal gland. Aldosterone plays a crucial role in regulating electrolyte and fluid balance in the body by increasing the reabsorption of sodium and excretion of potassium in the kidneys.

Hypoaldosteronism can lead to low blood pressure, muscle weakness, and an imbalance of electrolytes, particularly low serum sodium levels and high serum potassium levels. This condition can be caused by various factors, including damage to the adrenal gland, impaired production or function of aldosterone, or decreased responsiveness of the kidneys to aldosterone.

Hypoaldosteronism can be primary or secondary. Primary hypoaldosteronism is caused by a problem with the adrenal glands themselves, such as damage to the gland or a genetic disorder that affects aldosterone production. Secondary hypoaldosteronism is caused by a problem outside of the adrenal glands, such as decreased production of renin (an enzyme produced by the kidneys) or certain medications that interfere with aldosterone production or function.

Treatment for hypoaldosteronism depends on the underlying cause and may include medication to replace missing aldosterone or correct electrolyte imbalances, as well as addressing any underlying conditions contributing to the development of the condition.

Hyperkalemia is a medical condition characterized by an elevated level of potassium (K+) in the blood serum, specifically when the concentration exceeds 5.0-5.5 mEq/L (milliequivalents per liter). Potassium is a crucial intracellular ion that plays a significant role in various physiological processes, including nerve impulse transmission, muscle contraction, and heart rhythm regulation.

Mild to moderate hyperkalemia might not cause noticeable symptoms but can still have harmful effects on the body, particularly on the cardiovascular system. Severe cases of hyperkalemia (potassium levels > 6.5 mEq/L) can lead to potentially life-threatening arrhythmias and heart failure.

Hyperkalemia may result from various factors, such as kidney dysfunction, hormonal imbalances, medication side effects, trauma, or excessive potassium intake. Prompt identification and management of hyperkalemia are essential to prevent severe complications and ensure proper treatment.

Fludrocortisone is a synthetic corticosteroid hormone, specifically a mineralocorticoid. It is often used to treat conditions associated with low levels of corticosteroids, such as Addison's disease. It works by helping the body retain sodium and lose potassium, which helps to maintain fluid balance and blood pressure.

In medical terms, fludrocortisone is defined as a synthetic mineralocorticoid with glucocorticoid activity used in the treatment of adrenogenital syndrome and Addison's disease, and as an adjunct in the treatment of rheumatoid arthritis. It is also used to treat orthostatic hypotension by helping the body retain sodium and water, thereby increasing blood volume and blood pressure.

It is important to note that fludrocortisone can have significant side effects, particularly if used in high doses or for long periods of time. These can include fluid retention, high blood pressure, increased risk of infection, and slowed growth in children. As with any medication, it should be used under the close supervision of a healthcare provider.

Aldosterone is a hormone produced by the adrenal gland. It plays a key role in regulating sodium and potassium balance and maintaining blood pressure through its effects on the kidneys. Aldosterone promotes the reabsorption of sodium ions and the excretion of potassium ions in the distal tubules and collecting ducts of the nephrons in the kidneys. This increases the osmotic pressure in the blood, which in turn leads to water retention and an increase in blood volume and blood pressure.

Aldosterone is released from the adrenal gland in response to a variety of stimuli, including angiotensin II (a peptide hormone produced as part of the renin-angiotensin-aldosterone system), potassium ions, and adrenocorticotropic hormone (ACTH) from the pituitary gland. The production of aldosterone is regulated by a negative feedback mechanism involving sodium levels in the blood. High sodium levels inhibit the release of aldosterone, while low sodium levels stimulate its release.

In addition to its role in maintaining fluid and electrolyte balance and blood pressure, aldosterone has been implicated in various pathological conditions, including hypertension, heart failure, and primary hyperaldosteronism (a condition characterized by excessive production of aldosterone).

Renin is a medically recognized term and it is defined as:

"A protein (enzyme) that is produced and released by specialized cells (juxtaglomerular cells) in the kidney. Renin is a key component of the renin-angiotensin-aldosterone system (RAAS), which helps regulate blood pressure and fluid balance in the body.

When the kidney detects a decrease in blood pressure or a reduction in sodium levels, it releases renin into the bloodstream. Renin then acts on a protein called angiotensinogen, converting it to angiotensin I. Angiotensin-converting enzyme (ACE) subsequently converts angiotensin I to angiotensin II, which is a potent vasoconstrictor that narrows blood vessels and increases blood pressure.

Additionally, angiotensin II stimulates the adrenal glands to release aldosterone, a hormone that promotes sodium reabsorption in the kidneys and increases water retention, further raising blood pressure.

Therefore, renin plays a critical role in maintaining proper blood pressure and electrolyte balance in the body."

Adrenal insufficiency is a condition in which the adrenal glands do not produce adequate amounts of certain hormones, primarily cortisol and aldosterone. Cortisol helps regulate metabolism, respond to stress, and suppress inflammation, while aldosterone helps regulate sodium and potassium levels in the body to maintain blood pressure.

Primary adrenal insufficiency, also known as Addison's disease, occurs when there is damage to the adrenal glands themselves, often due to autoimmune disorders, infections, or certain medications. Secondary adrenal insufficiency occurs when the pituitary gland fails to produce enough adrenocorticotropic hormone (ACTH), which stimulates the adrenal glands to produce cortisol.

Symptoms of adrenal insufficiency may include fatigue, weakness, weight loss, decreased appetite, nausea, vomiting, diarrhea, abdominal pain, low blood pressure, dizziness, and darkening of the skin. Treatment typically involves replacing the missing hormones with medications taken orally or by injection.

Congenital Adrenal Hyperplasia (CAH) is a group of inherited genetic disorders that affect the adrenal glands, which are triangular-shaped glands located on top of the kidneys. The adrenal glands are responsible for producing several essential hormones, including cortisol, aldosterone, and androgens.

CAH is caused by mutations in genes that code for enzymes involved in the synthesis of these hormones. The most common form of CAH is 21-hydroxylase deficiency, which affects approximately 90% to 95% of all cases. Other less common forms of CAH include 11-beta-hydroxylase deficiency and 3-beta-hydroxysteroid dehydrogenase deficiency.

The severity of the disorder can vary widely, depending on the degree of enzyme deficiency. In severe cases, the lack of cortisol production can lead to life-threatening salt wasting and electrolyte imbalances in newborns. The excess androgens produced due to the enzyme deficiency can also cause virilization, or masculinization, of female fetuses, leading to ambiguous genitalia at birth.

In milder forms of CAH, symptoms may not appear until later in childhood or even adulthood. These may include early puberty, rapid growth followed by premature fusion of the growth plates and short stature, acne, excessive hair growth, irregular menstrual periods, and infertility.

Treatment for CAH typically involves replacing the missing hormones with medications such as hydrocortisone, fludrocortisone, and/or sex hormones. Regular monitoring of hormone levels and careful management of medication doses is essential to prevent complications such as adrenal crisis, growth suppression, and osteoporosis.

In severe cases of CAH, early diagnosis and treatment can help prevent or minimize the risk of serious health problems and improve quality of life. Genetic counseling may also be recommended for affected individuals and their families to discuss the risks of passing on the disorder to future generations.

Addison disease, also known as primary adrenal insufficiency or hypocortisolism, is a rare endocrine disorder characterized by the dysfunction and underproduction of hormones produced by the adrenal glands, specifically cortisol and aldosterone. The adrenal glands are located on top of the kidneys and play a crucial role in regulating various bodily functions such as metabolism, blood pressure, stress response, and immune system function.

The primary cause of Addison disease is the destruction of more than 90% of the adrenal cortex, which is the outer layer of the adrenal glands responsible for hormone production. This damage can be due to an autoimmune disorder where the body's immune system mistakenly attacks and destroys the adrenal gland tissue, infections such as tuberculosis or HIV, cancer, genetic disorders, or certain medications.

The symptoms of Addison disease often develop gradually and may include fatigue, weakness, weight loss, decreased appetite, low blood pressure, darkening of the skin, and mood changes. In some cases, an acute crisis known as acute adrenal insufficiency or Addisonian crisis can occur, which is a medical emergency characterized by sudden and severe symptoms such as extreme weakness, confusion, dehydration, vomiting, diarrhea, low blood sugar, and coma.

Diagnosis of Addison disease typically involves blood tests to measure hormone levels, imaging studies such as CT scans or MRIs to assess the adrenal glands' size and structure, and stimulation tests to evaluate the adrenal glands' function. Treatment usually involves replacing the missing hormones with medications such as hydrocortisone, fludrocortisone, and sometimes mineralocorticoids. With proper treatment and management, individuals with Addison disease can lead normal and productive lives.
