Ketoacidosis

Ketoacidosis

Ketoacidosis is a metabolic state associated with high concentrations of ketone bodies, formed by the breakdown of fatty acids and the deamination of amino acids. The two common ketones produced in humans are acetoacetic acid and β-hydroxybutyrate. Ketoacidosis is a pathological metabolic state marked by extreme and uncontrolled ketosis. In ketoacidosis, the body fails to adequately regulate ketone production causing such a severe accumulation of keto acids that the pH of the blood is substantially decreased. In extreme cases ketoacidosis can be fatal.[1] Ketoacidosis is most common in untreated type 1 diabetes mellitus, when the liver breaks down fat and proteins in response to a perceived need for respiratory substrate. Prolonged alcoholism may lead to alcoholic ketoacidosis. Ketoacidosis can be smelled on a person's breath. This is due to acetone, a direct by-product of the spontaneous decomposition of acetoacetic acid. It is often described as smelling like fruit or nail polish remover.[2] Ketosis may also give off an odor, but the odor is usually more subtle due to lower concentrations of acetone. Treatment consists most simply of correcting blood sugar and insulin levels, which will halt ketone production. If the severity of the case warrants more aggressive measures, intravenous sodium bicarbonate infusion can be given to raise blood pH back to an acceptable range. However, serious caution must be exercised with IV sodium bicarbonate to avoid the risk of equally life-threatening hypernatremia. Cause[edit] Three common causes of ketoacidosis are alcohol, starvation, and diabetes, resulting in alcoholic ketoacidosis, starvation ketoacidosis, and diabetic ketoacidosis respectively.[3] In diabetic ketoacidosis, a high concentration of ketone bodies is usually accomp Continue reading >>

DKA occurs as a consequence of absolute or relative insulin deficiency - K+ is loss due to shift of K+ from the intracellular to extracellular with exchange of hydrogen ions - acidosis -increase in catecholamines, cortisol, glucagon, and GH - leads to increase glucose production and decrease glucose use of tissue - insulin deficiency leads to reduced glucose uptake, increased fat mobilization with release of fatty acids, accelerated gluconeogenesis and ketogenesis. - increased ketone concentrations - ketones are used to regenerate bicarb - hyperketones may be a result of impairment in the use of ketones, which permits strong organic acid to circulate freely - bicarb buffering does not occur leading to metabolic acidosis Diabetic ketoacidosis (DKA) results from dehydration during a state of relative insulin deficiency, associated with high blood levels of sugar level and organic acids called ketones. Diabetic ketoacidosis is associated with significant disturbances of the body's chemistry, which resolve with proper therapy. Diabetic ketoacidosis usually occurs in people with type 1 (juvenile) diabetes mellitus (T1DM), but diabetic ketoacidosis can develop in any person with diabetes. Since type 1 diabetes typically starts before age 25 years, diabetic ketoacidosis is most common in this age group, but it may occur at any age. Males and females are equally affected.

Diabetic Ketoacidosis

Diabetic Ketoacidosis

Diabetic ketoacidosis (DKA) is a potentially life-threatening complication of diabetes mellitus.[1] Signs and symptoms may include vomiting, abdominal pain, deep gasping breathing, increased urination, weakness, confusion, and occasionally loss of consciousness.[1] A person's breath may develop a specific smell.[1] Onset of symptoms is usually rapid.[1] In some cases people may not realize they previously had diabetes.[1] DKA happens most often in those with type 1 diabetes, but can also occur in those with other types of diabetes under certain circumstances.[1] Triggers may include infection, not taking insulin correctly, stroke, and certain medications such as steroids.[1] DKA results from a shortage of insulin; in response the body switches to burning fatty acids which produces acidic ketone bodies.[3] DKA is typically diagnosed when testing finds high blood sugar, low blood pH, and ketoacids in either the blood or urine.[1] The primary treatment of DKA is with intravenous fluids and insulin.[1] Depending on the severity, insulin may be given intravenously or by injection under the skin.[3] Usually potassium is also needed to prevent the development of low blood potassium.[1] Throughout treatment blood sugar and potassium levels should be regularly checked.[1] Antibiotics may be required in those with an underlying infection.[6] In those with severely low blood pH, sodium bicarbonate may be given; however, its use is of unclear benefit and typically not recommended.[1][6] Rates of DKA vary around the world.[5] In the United Kingdom, about 4% of people with type 1 diabetes develop DKA each year, while in Malaysia the condition affects about 25% a year.[1][5] DKA was first described in 1886 and, until the introduction of insulin therapy in the 1920s, it was almost univ Continue reading >>
