Aldosterone and Hormone Replacement Therapy and Renal Dialysis
Aldosterone and Hormone Replacement Therapy

Aldosterone falls in the class of hormone called mineralocorticoids, produces by the adrenal glands and is found near the kidneys. It sustains blood pressure, water and salt balance within the body. This procedure is assisting the kidneys to preserve sodium and excrete potassium in order to maintain a balance. If Aldosterone production falls, there isn’t enough regulation of salt and water balance (as aldosterone is being lost through urination) triggering blood pressure and blood volume to decline as a result of the kidneys not functioning properly. If body is in need of salt, water is not retained and adrenals release more Aldosterone and salt is reabsorbed from the tubule.

Addison’s disease is a hormonal disorder that affects all age groups, both male and female. The disease is categorised depending on the individual, this may include; weight, low blood pressure darkening of skin etc. When an insufficient amount of the hormone, cortisol and some cases the hormone aldosterone is being produced from the adrenal glands, it causes the Addison’s disease to occur. Cortisol helps maintain blood pressure and cardiovascular function, slows immune systems inflammatory response, breaks down sugar for energy (balancing insulin levels) and helps regulate metabolism of proteins, carbohydrates and fats. The brains hypothalamus glands control and accurately balance the amounts of cortisol needed.

Symptoms of Addison’s disease are slow and progressive but if left untreated may become fatal. Worsening fatigue and muscle weakness, loss of appetite and weight loss are characteristic for this illness. In 50% of cases nausea, vomiting and diarrhoea are present. Skin changes are common – this is when certain areas of the skin (exposed or non-exposed) darken, most common on pressure points. Irritability and depression, salty food cravings, low blood sugar (usually in children) and irregular or no periods, for women, may occur.

    The elevated pressure in the arteries, reduces oxygen and blood flow to the brain, causing the heart to increase its workload and oxygen utilization. Also the elevated pressure decreases the blood flow and oxygenation of the kidneys. The nervous system comes into play when blood pressure drops. Blood pressure is then increased by activation of the sympathetic nervous system (SNS). Increased activity in the SNS causes elevated heart rate and cardiac contractility. However, causing the arteries to constrict and stimulate the kidneys to circulate renin. Therefore, by increasing CO and SVR blood pressure increases in return. The SNS activation is usually stimulate in the response to stress factors. The renal system is also a regulator for blood pressure. The blood pressure is regulated by the control of sodium excretion and extracellular fluid (ECF) volume. When sodium (Na+) is retained water (H2O) retained as well. As a result of Na+ and H2O, ECF volume increases which causes an increase in CO and blood pressure by the venous return to the heart and stroke…

    Stimulus for their release = if blood pressure drops dramatically this will trigger renin secretion from the JG cells, renin acts on angiotensinogen to form angiotensin I, angiotensin I is converted to angiotensin II therefore angiotensin II causes mean arterial pressure to rise and stimulates the adrenal cortex to release aldosterone. As a result, both systemic and glomerular hydrostatic pressure rises.…

    Corticotropin-releasing hormone (CRH) is released through a nerve impulse from the hypothalamus. It’s released in response to stress; the hormone is carried by neurons to the anterior lobe of the pituitary. Upon arrival in the pituitary gland it stimulates corticotrophs that in turn stimulate adrenocorticotropic hormone (ACTH). It is thought Cortisol is controlled by the quantity of calcium moving into the Cortisol secreting target cells. This circuit is part of a negative feedback loop, so as to ensure that Cortisol is not continually excreted. It is important that the negative feedback inhibits the hormones that trigger the production of more Cortisol. The reason being; one side effect of Cortisol is that it suppresses…

    The retention of water in the body will increase the level of sodium and potassium ions in the blood that causes the body to absorb more water is called Aldosterone. Aldosterone has secretion from the adrenal cortex that will regulate sodium and potassium in the body, causing the water retained in the body to increase. Mineralocorticoid, is any group of steroid hormones that has the similar characteristics of Aldosterone; and it has an influence on salt and water metabolism. Antidiuretic hormone (ADH), a secretion from the posterior pituitary gland that is responsible for the amount of water excreted from the kidneys. Kidneys have the ability to take on more water before any excretion happens; and it takes place in special channels called…

    High salt diet increases the amount of sodium in the blood stream. The high amount of sodium affects the kidneys’ ability to remove excess water from the blood, and this results in a high blood pressure due additional fluid. The kidneys use osmosis to extract excess water out of the blood. Sodium and potassium are the key factors that keep the balance of fluid across the cell walls in the bloodstream.…

    In pregnancy, the renin–angiotensin–aldosterone system (RAAS) plays an important role for the equilibrium of salt and water in mother and child. All components of the RAAS are altered during pregnancy (1, 2). Renin concentrations are elevated due to extra-renal secretion in decidua and ovaries through estrogen stimulation (2). An increase in angiotensinogen production in the liver is observed in pregnant women. By contrast, the angiotensin-converting enzyme is reduced. These changes result in an elevation in aldosterone and angiotensin II (ANGII) levels (3). Increased aldosterone secretion is also a physiological response to sodium loss in response to high progesterone concentrations, a competitive inhibitor of aldosterone at the renal tubulus…

    The hydroxylation of PROG to 11-deoxycorticosterone (11-deoxy COS) and OH PROG to 11-deoxycortisol (11-deoxy COR) is catalyzed by the enzyme 21β-hydroxylase known as CYP21A2 . 11-deoxy COS and 11-deoxy COR move back to the mitochondria and form COS and COR by the action of 11β-hydroxylase known as CYP11β1. Further on in the mitochondria the mineralocorticosteroid ALDO is formed from COS by the enzyme aldosterone synthase, which is also known as CYP11β2. COR moves back to the smooth endoplasmic reticulum where it is converted to the metabolic inactive cortisone (CORNE) by 11β-hydroxysteroid dehydrogenase (11β-HSD…

    For cortisol to be released from the adrenal gland, a cascade of signaling occurs. Corticotropin-releasing hormone released from the hypothalamus stimulates corticotrophs in the anterior pituitary to release ACTH, which relays the signal to the adrenal cortex. Here, the zona fasciculata and zona reticularis, in response to ACTH, secrete glucocorticoids, in particular cortisol. In the peripheral tissues, cortisol is converted to cortisone by the enzyme 11-beta-steroid dehydrogenase. Cortisol has much greater glucocorticoid activity than cortisone, and, thus, cortisone can be considered an inactive metabolite of cortisol. However, 11-beta-steroid dehydrogenase can catalyze the reverse reaction as well, and, thus, cortisone is also the inactive precursor molecule of the active hormone cortisol. Cortisone is activated through hydrogenation of the 11-keto-group, and cortisol is, thus, sometimes referred to as hydrocortisone.[citation needed]Cortisone is one of several end-products of a process called steroidogenesis. This process starts with the synthesis of cholesterol, which then proceeds through a series of modifications in the adrenal gland (suprarenal) to become any one of many steroid hormones. One…

    In humans the kidney plays a huge part in the osmoregulation of the body’s internal environment. Regulation of water in the human body is carried out through the excretion of waste urine from the body. Hormones which include: the antidiuretic hormone, aldosterone and angiotensin II are used in the body to help to increase the permeability of the collecting ducts found in the kidney. This further allows diffusing to occur easily, it also allows the kidney to be able to reabsorb water and prevent it from being excreted. Humans are also able to regulate by controlling the total amount of water that is passed out of the body through urine waste or sweat, this is carried out with the help of the excretory system.…
