Corrected anion gap hyperglycemia

Transcription

1 Corrected anion gap hyperglycemia Acute or chronic metabolic acidosis, including diabetic ketoacidosis. Initial fluid therapy is directed toward expansion of the intravascular, interstitial, and intracellular volume, all of which are reduced in hyperglycemic crises ( 53 ) and restoration of renal perfusion. In the absence of cardiac compromise, isotonic saline (0.9% NaCl) is infused at a rate of ml kg body wt 1 h 1 or l during the first hour. Subsequent choice for fluid replacement depends on hemodynamics, the state of hydration, serum electrolyte levels, and urinary output. In general, 0.45% NaCl infused at ml/h is appropriate if the corrected serum sodium is normal or elevated; 0.9% NaCl at a similar rate is appropriate if corrected serum sodium is low ( Fig. 2 ). Successful progress with fluid replacement is judged by hemodynamic monitoring (improvement in blood pressure), measurement of fluid input/output, laboratory values, and clinical examination. Fluid replacement should correct estimated deficits within the first 24 h. In patients with renal or cardiac compromise, monitoring of serum osmolality and frequent assessment of cardiac, renal, and mental status must be performed during fluid resuscitation to avoid iatrogenic fluid overload ( 4, 10, 15, 53 ). Aggressive rehydration with subsequent correction of the hyperosmolar state has been shown to result in a more robust response to low-dose insulin therapy ( 54 ). Consider the overall safety profile demonstrated for up to 6.5 years, including egfr over time 2,4. Doctors Encouraged to Assess Driving Risks for T1DM Patients. Monitor patients receiving INVOKANA / INVOKAMET /INVOKAMET XR for infection, new pain or tenderness, sores, or ulcers involving the lower limbs, and discontinue if these complications occur. The use of bicarbonate in DKA is controversial ( 62 ) because most experts believe that during the treatment, as ketone bodies decrease there will be adequate bicarbonate except in severely acidotic patients. Severe metabolic acidosis can lead to impaired myocardial contractility, cerebral vasodilatation and coma, and several gastrointestinal complications ( 63 ). A prospective randomized study in 21 patients failed to show either beneficial or deleterious changes in morbidity or mortality with bicarbonate therapy in DKA patients with an admission arterial ph between 6.9 and 7.1 ( 64 ). Nine small studies in a total of 434 patients with diabetic ketoacidosis (217 treated with bicarbonate and 178 patients without alkali therapy [( 62 )]) support the notion that bicarbonate therapy for DKA offers no advantage in improving cardiac or neurologic functions or in the rate of recovery of hyperglycemia and ketoacidosis. Moreover, several deleterious effects of bicarbonate therapy have been reported, such as increased risk of hypokalemia, decreased tissue oxygen uptake ( 65 ), cerebral edema ( 65 ), and development of paradoxical central nervous system acidosis. A-Fib Risk Up for Antidepressant Users, but Higher Before Tx. Priorities * to be addressed in the management of adults presenting with hyperglycemic emergencies. INVOKAMET and INVOKAMET XR are a combination of canagliflozin and metformin hydrochloride (HCl) indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus when treatment with both canagliflozin and metformin HCl is appropriate. Diabetic ketoacidosis

2 requires intravenous insulin administration (0.1 units/kg/h) for resolution. Bicarbonate therapy may be considered only for extreme acidosis (ph 7.0). Moderate to severe renal impairment (egfr below 45 ml/min/1.73 m 2 ), end stage renal disease (ESRD), or patients on dialysis. If you have type 1 diabetes with blood glucose levels remaining over 14 mmol/l before meals, or if you have symptoms of diabetic ketoacidosis (see Table 1 ), check for ketones by performing a urine ketone test or blood ketone test. Blood ketone testing is preferred over urine testing. Hepatic Impairment: Avoid use of INVOKAMET /INVOKAMET XR in patients with evidence of hepatic disease. Recent epidemiological studies indicate that hospitalizations for DKA in the U.S. are increasing. In the decade from 1996 to 2006, there was a 35% increase in the number of cases, with a total of 136,510 cases with a primary diagnosis of DKA in 2006 a rate of increase perhaps more rapid than the overall increase in the diagnosis of diabetes ( 1 ). Most patients with DKA were between the ages of 18 and 44 years (56%) and 45 and 65 years (24%), with only 18% of patients 1.0 ng/dl (0.33 nmol/l) and stimulated C-peptide levels >1.5 ng/dl (0.5 nmol/l) are predictive of long-term normoglycemic remission in patients with a history of DKA ( 28, 32 ). Insulin normally blocks ketogenesis by inhibiting the transport of FFA derivatives into the mitochondrial matrix, but ketogenesis proceeds in the absence of. Insulin deficiency causes the body to metabolize triglycerides and amino acids instead of glucose for energy. Serum levels of glycerol and free fatty acids (FFAs) rise because of unrestrained lipolysis, as does alanine because of muscle catabolism. Glycerol and alanine provide substrate for hepatic gluconeogenesis, which is stimulated by the excess of. Develop a sick-day plan with your diabetes health-care team. This should include information on: Amputations of the toe and midfoot (99 out of 140 patients with amputations receiving INVOKANA in the two trials) were the most frequent; however, amputations involving the leg, below and above the knee, were also observed (41 out of 140 patients with amputations receiving INVOKANA in the two trials). Some patients had multiple amputations, some involving both lower limbs. The key diagnostic feature in DKA is the elevation in circulating total blood ketone concentration. Assessment of augmented ketonemia is usually performed by the nitroprusside reaction, which provides a semiquantitative estimation of acetoacetate and acetone levels. Although the nitroprusside test (both in urine and in serum) is highly sensitive, it can underestimate the severity of ketoacidosis because this assay does not recognize the presence of β- hydroxybutyrate, the main metabolic product in ketoacidosis ( 4, 12 ). If available, measurement of serum β-hydroxybutyrate may be useful for diagnosis ( 37 ). Accumulation of ketoacids results in an increased anion gap metabolic acidosis. The anion gap is calculated by subtracting the sum of chloride and bicarbonate concentration from the sodium concentration: [Na (Cl + HCO 3 )]. A normal anion gap is between 7 and 9 meq/l and an anion gap >10 12 meq/l indicate the presence of increased anion gap metabolic acidosis ( 4 ). Steps to reduce the risk of and manage metformin-associated lactic acidosis in these high-risk groups are provided in the full prescribing information. Beta-OHB, beta-hydroxybutyric acid; DKA, diabetic ketoacidosis; ECFV, extracelluar fluid volume; IV, intravenous. *Plasma glucose may be lower than expected in some settings. **Anion gap = plasma [Na+] plasma [Cl ] plasma [HCO 3 ]. Corrected plasma [Na+] = measured [Na+] + 3/10 ([plasma glucose (mmol/l)] 5). Effective plasma osmolality = [Na+] 2 + [plasma glucose (mmol/l)], reported as mmol/kg. Glucagon also stimulates mitochondrial conversion of FFAs into ketones. INVOKANA is indicated to reduce the risk of major adverse cardiovascular events (cardiovascular death, nonfatal myocardial infarction, and nonfatal stroke) in adults with type 2 diabetes mellitus and established

DKA is the first manifestation of type 1 DM in a minority of patients. I'm confused about why you think that this is a HAGMA with appropriate resp compensation: AG=Na- (Cl+HCO3) ==> 152-(124+16)=12, which is normal. Compensation for the metabolic acidosis is 1.5*HCO3 + 8, => (1.5 16) + 8 ==> 32, so there is a concurrent respiratory alkalosis.. Gennari FJ. Current concepts. Serum osmolality. Uses and limitations. The normal anion gap depends on serum phosphate and serum albumin:. Acute Respiratory Acidosis (Chronic Respiratory Acidosis = COPD/restrictive lung dz): any hypoventilation state. A frequently encountered problem in clinical practice is a patient who presents with acidosis and hyperglycemia. It has been my experience that the correct calculation of the anion gap in the face of hyperglycemia is often confusing. An example would best serve to illustrate the point. Assume a patient who is admitted with new-onset diabetes mellitus and has the following blood test results: glucose level, 700 mg/dl; sodium level, 128 meq/l; chloride level, 97 meq/l; and bicarbonate level, 21 meq/l. The anion gap in this patient is [Na]? ([Bicarbonate] + [Cl]) = 128?( ) = 10, a value within normal limits; the patient has a mild non-anion gap acidosis. However, physicians often correct the sodium level in the face of hyperglycemia by adding 1.6 meq/l to the sodium concentration for each 100- mg/dl increment in glucose levels above 100 mg/dl. This correction does not apply to the calculation of the anion gap in patients with acidosis and hyperglycemia because the water moving from the intracellular compartment to the extracellular compartment as a result of the hyperglycemia equally dilutes all electrolytes, including the chloride and bicarbonate. If in this case the sodium level is "corrected" for the hyperglycemia, it will be calculated as 138 meq/l and lead to a falsely elevated calculated anion gap of 20. Thus, the patient's condition would be erroneously diagnosed as severe anion gap acidosis, most probably diabetic ketoacidosis. South Med J Feb; 81 (2): [ PubMed ]. The potassium is very low. This is particularly noteworthy given the degree of acidaemia. Acidaemia drives the potassium up so, as the acid base disturbance is corrected, the potassium will drop even further. While total potassium deficits can be difficult to predict on the basis of serum potassium, the total loss here is likely to be in the order of 100s mmols.

Abelcet should be administered by intravenous infusion at a rate of 2.5 mg/kg/h. If the infusion time exceeds 2 hours, mix the contents by shaking the infusion bag every 2 hours. Desloratadine; Pseudoephedrine: (Moderate) Sympathomimetic agents and adrenergic agonists tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when pseudoephedrine, phenylephrine, and other sympathomimetics are administered to patients taking antidiabetic agents. Epinephrine and other sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes. Hyperamylasemia has been reported in 21 79% of patients with DKA ( 48 ); however, there is little correlation between the presence, degree, or isoenzyme type of hyperamylasemia and the presence of gastrointestinal symptoms (nausea, vomiting, and abdominal pain) or pancreatic imaging studies ( 48 ). A serum lipase determination may be beneficial in the differential diagnosis of pancreatitis; however, lipase could also be elevated in DKA in the absence of pancreatitis ( 48 ). DKA occurs primarily in patients with type 1 diabetes. The incidence is

5 roughly 2 episodes per 100 patient years of diabetes, with about 3% of patients with type 1 diabetes initially presenting with DKA. It can occur in patients with type 2 diabetes as well; this is less common, however.
