Inappropriate Hyponatremia Essay

Vasopressin (Antidiuretic hormone) also is oxidized by the oxygen released from erythrocytes. Vasopressin plays a role in circulatory homeostasis and serum osmolality. Oxytocin and vasopressin are oxidized with formation of dityrosine [77]. Its oxidation and depletion cause vasodilatory shock - a syndrome with high mortality [78-81]. Low expression levels of Angiotensin II and ACE (angiotensin converting enxyme) are valuable in predicting the mortality of patients

The extreme amount of support from clinical trials and investigations has supported the use of ACE inhibitors in various forms of pathologies (Ramos-Nino et al. 2009). ACE inhibitors have proven to reduce blood pressure, and to reduce to the possibility of death in heart failure patients. In earlier trails, patients with left ventricular dysfunction showed reduced numbers in myocardial infarctions. A few further investigations had suggested that ace inhibitors could affect atherosclerosis regardless of its effect on hypertension and ventricular function. Ace inhibitor users for nephropathy in patients with type 1 diabetes showed reduced signs in death and dialysis. Patients named at a high-risk level (80% and higher chance of death) who received ACE inhibitor treatments were found to have a 22% risk reduction in cardiovascular death or stroke (Lala et al. 2008). New evidence shows that ACE inhibitors are effective in reducing myocardial injury to the coronary arteries during a bypass graft surgery (CABG), and can prevent future problems years after the surgery. Not only are ACE inhibitors good for CABG patients due to their antihypertensive effects, they have also shown to be good through their vasculoprotective and antiatherogenic properties. In an overall view of hypertension, the use of ACE inhibitors has resulted in an increase in lives

The cleaved residues will be classified as angiotensin 1 and will be converted by ACE into angiotensin 2 (Casas et al., 2005; Mechanisms and Robertson, 2010) Angiotensin is the active form that will stimulate the adrenal glands to release aldosterone. The role of ACE inhibitors in this system will be the blockage of the conversion of angiotensin 1 to angiotensin 2. All of this inhibition occurs in the kidney, blood vessels, the brain, adrenal glands as well as the heart (Casas et al., 2005; Mechanisms and Robertson, 2010). As a result it is identified that there will be an increase in the amount of sodium and urine excreted from the body as well as a decrease resistance of blood vessels in the kidney, decrease in cardiac output and volume (Mechanisms and Robertson, 2010; (Myles et al., 2009). There will also be an increase in venous capacity (Mechanisms and Robertson, 2010; (Myles et al.,

Based on their symptoms, it is likely that the relative has hypoglycaemia, a condition wherein people have abnormally low blood glucose levels. Hypoglycaemia is characterised by insulin excess, and results from increased hepatic gluconeogenesis and glycogenolysis, and when there is decreased glucose uptake and use by many tissues. The adrenal cortex secrets steroid hormones known as corticosteroids, which have three functional categories secreted in various areas. One of these includes the glucocorticoids, which controls the metabolism of glucose and various organic molecules.1 Cortisol, the predominant glucocorticoids, stimulates hepatic gluconeogenesis, which is the conversion of non-carbohydrate, into carbohydrate sources. When fasting,

The RAS is a hormone system that is responsible for maintaining homeostasis in relation to vasodilation or vasoconstriction, vascular or cardiac cell growth and mediating oxidative stress. (Vlachogiannakos et. al. 2001) The RAS is under sympathetic nervous control and can be influenced by an individuals weight, diet or amount of insulin. (White 2007) As illustrated by figure 1, The RAS involves the release of angiotensinogen from the liver, which undergoes cleavage by renin to produce Angiotensin I. This is then converted to angiotensin II by ACE. Angiotensin II is a powerful vasoconstrictor as well as being able to induce vascular and cardiac myocyte growth, and increases oxidative stress in cardiovascular and renal tissues. All the effects of angiotensin II assist in

It has been proposed that pulmonary vasoconstriction occurs as an early event of PAH, and is due to abnormal potassium channel expression and endothelial dysfunction. The endothelium is a key regulator of vascular tone and subsequently blood pressure. Endothelial dysfunction results in chronic release of vasoconstrictive agents such as endothelin-1 (ET-1) and impaired production of vasodilatory agents such as nitric oxide (NO) and prostacyclin(2). The effects of the sustained increase in ET-1 seen in PAH makes this molecule a major pharmacological

Symptoms, including hyperventilation(deep breathing), insulin deficiency, neurologic change, irregular pulse, ventricular fibrillation, confusion, weakness, headache, lethargy…

Suspicion may initially result from the characteristic ‘cushingoid’ appearance in addition to a history of taking steroids. Levels of cortisol can be tested from saliva or a 24-hour urine collection. Levels of ACTH in the blood are also measured, along with potassium. Additional tests may be done to locate the cause, such as a tumor. (Williams, L., & Hopper, P., 2015)

Examinations like blood sugar estimation, thyroid hormone tests, ultrasound of the stomach and pelvis are done. At times, serum androgens, luteinising hormone and other hormone estimates might be ordered.

This is a hormone that whose main function is to constrict blood vessels. This constriction increases the amount of energy needed to pump blood around the body and can cause high blood pressure. This can be dangerous for the heart if it had been weakened by heart attack. By blocking the production of Angiotensin II with ACE inhibitors this, in turn prevents constriction and lowers blood pressure (American Heart Association, 2015). ACE inhibitors also help to stop angiotensin I from converting into angiotensin II. By doing this there is a reduction in dilation of the blood vessels. There is also a reduction of the amount of water returned to the blood by the kidneys which ultimately leads to decreased blood pressure (Kenny,

Hypertension plays a major role in the development and progression of macrovascular and microvascular complications. Antihpertensive drugs may promote the development of type 2 diabetes mellitus. Studies indicate that the use of angiotensin converting enzyme inhibitors and angiotensin II receptor antagonists leads to less new onset diabetes compared to beta-blockers, diuretics.Recently, new guidelines for the treatment of hypertension have recommended the use of angiotensin converting enzyme inhibitors and angiotensin receptor blockers either singly or in combination with other drugs depending on blood pressure.

ACE inhibitors block the conversion of angiotensin I to angiotensin II and the effects of angiotensin II are therefore prevented. This competitive inhibition of ACE to prevent the formation of angiotensin II occurs in the kidney, blood vessels, heart, brain and adrenal gland This leads to an increase in the amount of sodium and urine excreted, reduced resistance in kidney blood vessels, an increase in venous capacity and decreases in cardiac output, stroke work and volume.

Atacand HCT (Candesartan celexetil-hydrochlorothiazide) was developed for patients who were unsuccessfully treated with single antihypertensive agents. The proposed benefit is elicited by the drugs action on angiotensin II receptor antagonists, the agent that causes vasoconstriction. Additionally the second ingredient hydrochlorothiazide a diuretic reduces blood pressure by improving the kidneys ability to eliminate salt and fluid from the body (www.centerwatch.com).

TSH, LH, Prolactin, HbA1c, T3, T4, and lipid profile. Rationale: There could be underlying factors such as diabetes, hypothyroidism or other endocrine disorders. The Thyroid hormone test the amount of TSH in the blood which can determine the functionality of the thyroid hormone. An under active or over active thyroid gland could cause irregularities in menstruation (NIH, 2017). I would also order CBC, CMP and Vitamin D level.
