Diagnosis And Treatment Of Diabetic Ketoacidosis And The Hyperglycemic Hyperosmolar State

Diagnosis And Treatment Of Diabetic Ketoacidosis And The Hyperglycemic Hyperosmolar State

Go to: Pathogenesis In both DKA and HHS, the underlying metabolic abnormality results from the combination of absolute or relative insulin deficiency and increased amounts of counterregulatory hormones. Glucose and lipid metabolism When insulin is deficient, the elevated levels of glucagon, catecholamines and cortisol will stimulate hepatic glucose production through increased glycogenolysis and enhanced gluconeogenesis4 (Fig. 1). Hypercortisolemia will result in increased proteolysis, thus providing amino acid precursors for gluconeogenesis. Low insulin and high catecholamine concentrations will reduce glucose uptake by peripheral tissues. The combination of elevated hepatic glucose production and decreased peripheral glucose use is the main pathogenic disturbance responsible for hyperglycemia in DKA and HHS. The hyperglycemia will lead to glycosuria, osmotic diuresis and dehydration. This will be associated with decreased kidney perfusion, particularly in HHS, that will result in decreased glucose clearance by the kidney and thus further exacerbation of the hyperglycemia. In DKA, the low insulin levels combined with increased levels of catecholamines, cortisol and growth hormone will activate hormone-sensitive lipase, which will cause the breakdown of triglycerides and release of free fatty acids. The free fatty acids are taken up by the liver and converted to ketone bodies that are released into the circulation. The process of ketogenesis is stimulated by the increase in glucagon levels.5 This hormone will activate carnitine palmitoyltransferase I, an enzyme that allows free fatty acids in the form of coenzyme A to cross mitochondrial membranes after their esterification into carnitine. On the other side, esterification is reversed by carnitine palmitoyltransferase I Continue reading >>

> Hyperglycemia And Diabetic Ketoacidosis

When blood glucose levels (also called blood sugar levels) are too high, it's called hyperglycemia. Glucose is a sugar that comes from foods, and is formed and stored inside the body. It's the main source of energy for the body's cells and is carried to each through the bloodstream. But even though we need glucose for energy, too much glucose in the blood can be unhealthy. Hyperglycemia is the hallmark of diabetes — it happens when the body either can't make insulin (type 1 diabetes) or can't respond to insulin properly (type 2 diabetes). The body needs insulin so glucose in the blood can enter the cells to be used for energy. In people who have developed diabetes, glucose builds up in the blood, resulting in hyperglycemia. If it's not treated, hyperglycemia can cause serious health problems. Too much sugar in the bloodstream for long periods of time can damage the vessels that supply blood to vital organs. And, too much sugar in the bloodstream can cause other types of damage to body tissues, which can increase the risk of heart disease and stroke, kidney disease, vision problems, and nerve problems in people with diabetes. These problems don't usually show up in kids or teens with diabetes who have had the disease for only a few years. However, they can happen in adulthood in some people, particularly if they haven't managed or controlled their diabetes properly. Blood sugar levels are considered high when they're above someone's target range. The diabetes health care team will let you know what your child's target blood sugar levels are, which will vary based on factors like your child's age. A major goal in controlling diabetes is to keep blood sugar levels as close to the desired range as possible. It's a three-way balancing act of: diabetes medicines (such as in Continue reading >>

Diabetic Ketoacidosis (dka) - Topic Overview

Diabetic Ketoacidosis (dka) - Topic Overview

Diabetic ketoacidosis (DKA) is a life-threatening condition that develops when cells in the body are unable to get the sugar (glucose) they need for energy because there is not enough insulin. When the sugar cannot get into the cells, it stays in the blood. The kidneys filter some of the sugar from the blood and remove it from the body through urine. Because the cells cannot receive sugar for energy, the body begins to break down fat and muscle for energy. When this happens, ketones, or fatty acids, are produced and enter the bloodstream, causing the chemical imbalance (metabolic acidosis) called diabetic ketoacidosis. Ketoacidosis can be caused by not getting enough insulin, having a severe infection or other illness, becoming severely dehydrated, or some combination of these things. It can occur in people who have little or no insulin in their bodies (mostly people with type 1 diabetes but it can happen with type 2 diabetes, especially children) when their blood sugar levels are high. Your blood sugar may be quite high before you notice symptoms, which include: Flushed, hot, dry skin. Feeling thirsty and urinating a lot. Drowsiness or difficulty waking up. Young children may lack interest in their normal activities. Rapid, deep breathing. A strong, fruity breath odor. Loss of appetite, belly pain, and vomiting. Confusion. Laboratory tests, including blood and urine tests, are used to confirm a diagnosis of diabetic ketoacidosis. Tests for ketones are available for home use. Keep some test strips nearby in case your blood sugar level becomes high. When ketoacidosis is severe, it must be treated in the hospital, often in an intensive care unit. Treatment involves giving insulin and fluids through your vein and closely watching certain chemicals in your blood (electrolyt Continue reading >>

Diabetic Ketoacidosis - Symptoms

Diabetic Ketoacidosis - Symptoms

A A A Diabetic Ketoacidosis 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 occurs when a person with diabetes becomes dehydrated. As the body produces a stress response, hormones (unopposed by insulin due to the insulin deficiency) begin to break down muscle, fat, and liver cells into glucose (sugar) and fatty acids for use as fuel. These hormones include glucagon, growth hormone, and adrenaline. These fatty acids are converted to ketones by a process called oxidation. The body consumes its own muscle, fat, and liver cells for fuel. In diabetic ketoacidosis, the body shifts from its normal fed metabolism (using carbohydrates for fuel) to a fasting state (using fat for fuel). The resulting increase in blood sugar occurs, because insulin is unavailable to transport sugar into cells for future use. As blood sugar levels rise, the kidneys cannot retain the extra sugar, which is dumped into the urine, thereby increasing urination and causing dehydration. Commonly, about 10% of total body fluids are lost as the patient slips into diabetic ketoacidosis. Significant loss of potassium and other salts in the excessive urination is also common. The most common Continue reading >>

Diabetic Ketoacidosis

Diabetic Ketoacidosis

Diabetic ketoacidosis (DKA) is a serious problem that can occur in people with diabetes if their body starts to run out of insulin. This causes harmful substances called ketones to build up in the body, which can be life-threatening if not spotted and treated quickly. DKA mainly affects people with type 1 diabetes, but can sometimes occur in people with type 2 diabetes. If you have diabetes, it's important to be aware of the risk and know what to do if DKA occurs. Symptoms of diabetic ketoacidosis Signs of DKA include: needing to pee more than usual being sick breath that smells fruity (like pear drop sweets or nail varnish) deep or fast breathing feeling very tired or sleepy passing out DKA can also cause high blood sugar (hyperglycaemia) and a high level of ketones in your blood or urine, which you can check for using home-testing kits. Symptoms usually develop over 24 hours, but can come on faster. Check your blood sugar and ketone levels Check your blood sugar level if you have symptoms of DKA. If your blood sugar is 11mmol/L or over and you have a blood or urine ketone testing kit, check your ketone level. If you do a blood ketone test: lower than 0.6mmol/L is a normal reading 0.6 to 1.5mmol/L means you're at a slightly increased risk of DKA and should test again in a couple of hours 1.6 to 2.9mmol/L means you're at an increased risk of DKA and should contact your diabetes team or GP as soon as possible 3mmol/L or over means you have a very high risk of DKA and should get medical help immediately If you do a urine ketone test, a result of more than 2+ means there's a high chance you have DKA. When to get medical help Go to your nearest accident and emergency (A&E) department straight away if you think you have DKA, especially if you have a high level of ketones in Continue reading >>

Diagnosis And Treatment Of Diabetic Ketoacidosis (dka) In Dogs And Cats

What is DKA in Dogs and Cats? Diabetic Ketoacidosis (DKA) is a serious and life-threatening complication of diabetes mellitus that can occur in dogs and cats. DKA is characterized by hyperglycemia, ketonemia, +/- ketonuria, and metabolic acidosis. Ketone bodies are formed by lipolysis (breakdown) of fat and beta-oxidation when the metabolic demands of the cells are not met by the limited intracellular glucose concentrations. This provides alternative energy sources for cells, which are most important for the brain. The three ketones that are formed include beta-hydroxybutyrate, acetoacetate and acetone. Beta-hydroxybutyrate (BHB) and acetoacetate are anions of moderately strong acids contributing most to the academia (low blood pH). Acetone is the ketone body that can be detected on breath. In a normal animal, glucose enters the cell (with help of insulin) – undergoes glycolysis to pyruvate within cytosol – pyruvate moves into mitochondria (energy generating organelle in the cell) to enter the TCA cycle and ATP is formed. ATP is the main energy source of the body. When glucose cannot enter the cell, free fatty acids are broken down (lipolysis) and move into the cell to undergo beta-oxidation (creation of pyruvate). The pyruvate then moves into the mitochondria to enter the TCA cycle (by conversion to Acetyl-CoA first). However, when the TCA cycle is overwhelmed, the Acetyl-CoA is used in ketogenesis to form ketone bodies. Summary Diabetic Ketoacidosis (DKA) in Dogs and Cats When there is no insulin the body cannot utilize glucose and there is no intracellular glucose. The body then uses ketone bodes as an alternate source. When there is decreased insulin and increased counterregulatory hormones fatty acids are converted to AcCoA and then ketones. In the non-diabetic Continue reading >>

Assistant Professor of Medicine, Division of Endocrinology, Diabetes & Metabolism, The University of Tennessee Health Science Center, 920 Madison Avenue, Suite 300A, Memphis, TN 38163 Clinical Recognition Omission of insulin and infection are the two most common precipitants of DKA. Non-compliance may account for up to 44% of DKA presentations; while infection is less frequently observed in DKA patients. Acute medical illnesses involving the cardiovascular system (myocardial infarction, stroke, acute thrombosis) and gastrointestinal tract (bleeding, pancreatitis), diseases of endocrine axis (acromegaly, Cushing`s syndrome, hyperthyroidism) and impaired thermo-regulation or recent surgical procedures can contribute to the development of DKA by causing dehydration, increase in insulin counter-regulatory hormones, and worsening of peripheral insulin resistance. Medications such as diuretics, beta-blockers, corticosteroids, second-generation anti-psychotics, and/or anti-convulsants may affect carbohydrate metabolism and volume status and, therefore, could precipitateDKA. Other factors: psychological problems, eating disorders, insulin pump malfunction, and drug abuse. It is now recognized that new onset T2DM can manifest with DKA. These patients are obese, mostly African Americans or Hispanics and have undiagnosed hyperglycemia, impaired insulin secretion, and insulin action. A recent report suggests that cocaine abuse is an independent risk factor associated with DKA recurrence. Pathophysiology In Continue reading >>

Delayed Diagnosis Of Diabetic Ketoacidosis In Children—a Cause For Concern

Delayed Diagnosis Of Diabetic Ketoacidosis In Children—a Cause For Concern

Abstract Diabetic ketoacidosis (DKA) is the major cause for mortality in children with diabetes mellitus (DM). Delayed diagnosis or missed diagnosis is common among children with DKA. This study was undertaken to identify the impact of delayed diagnosis on clinical presentation, complications, and mortality of DKA in children from a tertiary care center at Chennai. Among the 118 episodes of DKA in 100 children less than 12 years of age, delayed diagnosis was more common in new onset diabetes mellitus (DM). Forty-four out of 68 children with new onset DM with DKA (64.7 %) had delayed diagnosis. Thirty-two children with established diabetes presented with 50 episodes of DKA. Among these, eight episodes (16 %) had a delay in diagnosis; 85.7 % of infants, 76.9 % of toddlers, and 58 % of the preschool and school children had delayed diagnosis. Urinary tract infections, respiratory illness, vomiting, febrile illness, acute abdomen, and encephalopathy were the common diagnosis in children where DKA was missed. The causes for delay in diagnosis and management of DKA were lack of parental and physician awareness, improper referral, and delayed transport. Presence of shock, altered sensorium, severe DKA, lower PaCO2 at admission, and complications like renal failure and cerebral edema were higher in children with delayed diagnosis of DKA. This was found to be statistically significant. Delayed diagnosis was a significant risk factor for mortality in children with DKA (p = 0.00) in this study population. Continue reading >>

Diagnosis Of Diabetic Ketoacidosis

Diagnosis Of Diabetic Ketoacidosis

If you have symptoms suggestive of diabetic ketoacidosis (DKA), your doctor will take a medical history, do physical exam and various blood tests to confirm the same. Medical history and physical examination: Your doctor may ask question such as: Do you have diabetes? What medication do you take? Have you missed your insulin dose/s? How long have you had the symptoms (such as vomiting, pain abdomen and increased urination)? Have you been treated for DKA before? Tests that are done to diagnose diabetic ketoacidosis include: Blood sugar level: Insulin deficiency does not allow sugar to enter the cells and therefore, the blood sugar level will rise (hyperglycemia) and the body may start using fat and protein for energy. Blood sugar levels in diabetic ketoacidosis are higher than 250 mg per dL (13.9 mmol per L) and if it is not treated, the sugar level will continue to rise. Ketone level: Use of fat leads to the formation of a fat breakdown product called ketones. Ketones can be detected by urine or blood tests. Urine and blood tests for ketones are positive in people with diabetic ketoacidosis. Blood acidity: Increase in ketone levels in blood will make your blood acidic (acidosis). In people with moderate DKA, the pH is 7.00 to 7.24 and in severe DKA, the pH is less than 7.00.Decrease in pH (acidosis) can damage organs throughout your body. Arterial blood is tested to determine blood pH. Blood bicarbonate level: Bicarbonate in blood is usually low in DKA. In mild DKA, it is 15 to 18mEq per L, in moderate DKA, the level is about 10 to 15mEq per L and in severe DKA, it is less than 10 mEq per L. It may be normal or high in patients with vomiting, diuretic use or alkali ingestion. Other tests: Other tests that may be done to identify any underlying health problems that may h Continue reading >>

Diagnosis And Treatment Of Diabetic Ketoacidosis

Diagnosis And Treatment Of Diabetic Ketoacidosis

85 Abstract Diabetic ketoacidosis (DKA) is the most frequent hyperglycaemic acute diabetic complication. Furthermore it carries a significant risk of death, which can be prevented by early and effective management. All physicians, irrespective of the discipline they are working in and whether in primary, secondary or tertiary care institutions, should be able to recognise DKA early and initiate management immediately. 86 Introduction Diabetic ketoacidosis (DKA) is a common complication of diabetes with an annual occurrence rate of 46 to 50 per 10 000 diabetic patients. The severity of this acute diabetic complication can be appreciated from the high death-to-case ratio of 5 to 10%.1 In Africa the mortality of DKA is unacceptably high with a reported death rate of 26 to 29% in studies from Kenya, Tanzania and Ghana.2 It is a complication of both type 1 and type 2 diabetes mellitus, although more commonly seen in type 1 diabetic patients. Of known diabetic patients presenting with DKA about one-quarter will be patients with type 2 diabetes. In patients presenting with a DKA as first manifestation of diabetes about 15% will be type 2.3 This correlates well with data from South Africa suggesting that one- quarter of patients with DKA will be type 2 with adequate C-peptide levels and the absence of anti-GAD antibodies.4 This review will focus on the principles of diagnosis, monitoring and treatment of DKA, with special mention of new developments and controversial issues. Clinical features DKA evolves over hours to days in both type 1 and type 2 diabetic patients, but the symptoms of poor control of blood glucose are usually present for several days before the onset or presentation of ketoacidosis.5 The clinical features of DKA are non-specific and patients may present with Continue reading >>

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 >>

Alcoholic Ketoacidosis

Alcoholic Ketoacidosis

Alcoholic ketoacidosis is a metabolic complication of alcohol use and starvation characterized by hyperketonemia and anion gap metabolic acidosis without significant hyperglycemia. Alcoholic ketoacidosis causes nausea, vomiting, and abdominal pain. Diagnosis is by history and findings of ketoacidosis without hyperglycemia. Treatment is IV saline solution and dextrose infusion. Alcoholic ketoacidosis is attributed to the combined effects of alcohol and starvation on glucose metabolism. Alcohol diminishes hepatic gluconeogenesis and leads to decreased insulin secretion, increased lipolysis, impaired fatty acid oxidation, and subsequent ketogenesis, causing an elevated anion gap metabolic acidosis. Counter-regulatory hormones are increased and may further inhibit insulin secretion. Plasma glucose levels are usually low or normal, but mild hyperglycemia sometimes occurs. Diagnosis requires a high index of suspicion; similar symptoms in an alcoholic patient may result from acute pancreatitis, methanol or ethylene glycol poisoning, or diabetic ketoacidosis (DKA). In patients suspected of having alcoholic ketoacidosis, serum electrolytes (including magnesium), BUN and creatinine, glucose, ketones, amylase, lipase, and plasma osmolality should be measured. Urine should be tested for ketones. Patients who appear significantly ill and those with positive ketones should have arterial blood gas and serum lactate measurement. The absence of hyperglycemia makes DKA improbable. Those with mild hyperglycemia may have underlying diabetes mellitus, which may be recognized by elevated levels of glycosylated Hb (HbA1c). Typical laboratory findings include a high anion gap metabolic acidosis, ketonemia, and low levels of potassium, magnesium, and phosphorus. Detection of acidosis may be com Continue reading >>
