What Is Anion Gap Metabolic Acidosis?

Metabolic Acidosis; Gap Positive

Metabolic Acidosis; Gap Positive

Metabolic acidosis is defined by low serum pH (less than 7.35-7.45) and low serum bicarbonate. It occurs by one of three major mechanisms: 1. Increased endogenous acid (i.e., lactic acidosis, diabetic ketoacidosis). 2. Decreased renal acid excretion (i.e., renal failure). In determining the underlying etiology for a metabolic acidosis, the serum anion gap must be calculated by subtracting the major measured anions (chloride and bicarbonate) from the major measured cation (sodium). If the result is greater than 12 meq/L (which is the normal value for most laboratories), the acidosis is said to be an anion gap acidosis. The expected anion gap should is lower in hypoalbuminemia and should be corrected - for each decrease of 1gm/dl in albumin, the normal anion gap should be decreased by approximately 2.5 meq/L. A. What is the differential diagnosis for this problem? Anion gap acidosis can be the result from: 1. A fall in unmeasured cations (as seen in hypomagnesemia or hypocalcemia). The most common reasons for a rise in anions are ingestions, lactic acidosis, ketoacidosis and renal failure. Ingestions of multiple different toxins can result in unmeasured anions causing a metabolic gap acidosis. Most commonly salicylate and the alcohols (methanol and ethylene glycol) can lead to severe acidosis. The inhalant toluene may also be a culprit. Lactic acidosis is the most common cause of an elevated anion gap acidosis in hospitalized patients, occurring with decreased perfusion causing relative tissue ischemia. This leads to increased lactic acid production and impaired renal excretion with resultant acid accumulation (Type A lactic acidosis). Type B lactic acidosis occurs in patients without overt tissue and can be seen in diabetics on metformin, patients with hematologic and s Continue reading >>

For additional information: Background: Normal anion gap metabolic acidosis is a common but often misdiagnosed clinical condition associated with diarrhea and renal tubular acidosis (RTA). Early identification of RTA remains challenging for inexperienced physicians, and diagnosis and treatment are often delayed. Summary: The presence of RTA should be considered in any patient with a high chloride level when the CL-/Na+ ratio is above 0.79, if the patient does not have diarrhea. In patients with significant hyperkalemia one should evaluate for RTA type 4, especially in diabetic patients, with a relatively conserved renal function. A still growing list of medications can produce RTA. Key Messages: This review highlights practical aspects concerning normal anion gap metabolic acidosis.

Anion Gap

Anion Gap

OVERVIEW Anion Gap = Na+ – (Cl- + HCO3-) The Anion Gap (AG) is a derived variable primarily used for the evaluation of metabolic acidosis to determine the presence of unmeasured anions The normal anion gap depends on serum phosphate and serum albumin concentrations An elevated anion gap strongly suggests the presence of a metabolic acidosis The normal anion gap varies with different assays, but is typically 4 to 12mmol/L (if measured by ion selective electrode; 8 to 16 if measured by older technique of flame photometry) If AG > 30 mmol/L then metabolic acidosis invariably present If AG 20-29mmol/L then 1/3 will not have a metabolic acidosis K can be added to Na+, but in practice offers little advantage ALBUMIN AND PHOSPHATE the normal anion gap depends on serum phosphate and serum albumin the normal AG = 0.2 x [albumin] (g/L) + 1.5 x [phosphate] (mmol/L) albumin is the major unmeasured anion and contributes almost the whole of the value of the anion gap. every 1g/L decrease in albumin will decrease anion gap by 0.25 mmoles a normally high anion gap acidosis in a patient with hypoalbuminaemia may appear as a normal anion gap acidosis. this is particularly relevant in ICU patients where lower albumin levels are common HIGH ANION GAP METABOLIC ACIDOSIS (HAGMA) HAGMA results from accumulation of organic acids or impaired H+ excretion Causes (LTKR) Lactate Toxins Ketones Renal Causes (CATMUDPILES) CO, CN Alcoholic ketoacidosis and starvation ketoacidosis Toluene Metformin, Methanol Uremia DKA Pyroglutamic acidosis, paracetamol, phenformin, propylene glycol, paraladehyde Iron, Isoniazid Lactic acidosis Ethylene glycol Salicylates Effects of albumin Anion gap may be underesitmated in hypoalbuminaemia, because if albumin decreased by 1g/L then the anion gap decreases by 0.25 Continue reading >>

Serum Anion Gap: Its Uses And Limitations In Clinical Medicine

Serum Anion Gap: Its Uses And Limitations In Clinical Medicine

Abstract The serum anion gap, calculated from the electrolytes measured in the chemical laboratory, is defined as the sum of serum chloride and bicarbonate concentrations subtracted from the serum sodium concentration. This entity is used in the detection and analysis of acid-base disorders, assessment of quality control in the chemical laboratory, and detection of such disorders as multiple myeloma, bromide intoxication, and lithium intoxication. The normal value can vary widely, reflecting both differences in the methods that are used to measure its constituents and substantial interindividual variability. Low values most commonly indicate laboratory error or hypoalbuminemia but can denote the presence of a paraproteinemia or intoxication with lithium, bromide, or iodide. Elevated values most commonly indicate metabolic acidosis but can reflect laboratory error, metabolic alkalosis, hyperphosphatemia, or paraproteinemia. Metabolic acidosis can be divided into high anion and normal anion gap varieties, which can be present alone or concurrently. A presumed 1:1 stoichiometry between change in the serum anion gap (ΔAG) and change in the serum bicarbonate concentration (ΔHCO3−) has been used to uncover the concurrence of mixed metabolic acid-base disorders in patients with high anion gap acidosis. However, recent studies indicate variability in the ΔAG/ΔHCO3− in this disorder. This observation undercuts the ability to use this ratio alone to detect complex acid-base disorders, thus emphasizing the need to consider additional information to obtain the appropriate diagnosis. Despite these caveats, calculation of the serum anion gap remains an inexpensive and effective tool that aids detection of various acid-base disorders, hematologic malignancies, and intoxication Continue reading >>

(Video) Overview of Acid-Base Maps and Compensatory Mechanisms By James L. Lewis, III, MD, Attending Physician, Brookwood Baptist Health and Saint Vincent’s Ascension Health, Birmingham Metabolic acidosis is primary reduction in bicarbonate (HCO3−), typically with compensatory reduction in carbon dioxide partial pressure (Pco2); pH may be markedly low or slightly subnormal. Metabolic acidoses are categorized as high or normal anion gap based on the presence or absence of unmeasured anions in serum. Causes include accumulation of ketones and lactic acid, renal failure, and drug or toxin ingestion (high anion gap) and GI or renal HCO3− loss (normal anion gap). Symptoms and signs in severe cases include nausea and vomiting, lethargy, and hyperpnea. Diagnosis is clinical and with ABG and serum electrolyte measurement. The cause is treated; IV sodium bicarbonate may be indicated when pH is very low. Metabolic acidosis is acid accumulation due to Increased acid production or acid ingestion Acidemia (arterial pH < 7.35) results when acid load overwhelms respiratory compensation. Causes are classified by their effect on the anion gap (see The Anion Gap and see Table: Causes of Metabolic Acidosis ). Lactic acidosis (due to physiologic processes) Lactic acidosis (due to exogenous toxins) Toluene (initially high gap; subsequent excretion of metabolites normalizes gap) HIV nucleoside reverse transcriptase inhibitors Biguanides (rare except with acute kidney injury) Normal anion gap (hyperchloremic acidosis) Renal tubular acidosis, types 1, 2, and 4 The most common causes of a high anion gap metabolic acidosis are Ketoacidosis is a common complication of type 1 diabetes mellitus (see diabetic ketoacidosis ), but it also occurs with chronic alcoholism (see alcoholic ketoacidos Continue reading >>

High Anion Gap Metabolic Acidosis

High Anion Gap Metabolic Acidosis

When acidosis is present on blood tests, the first step in determining the cause is determining the anion gap. If the anion gap is high (>12 mEq/L), there are several potential causes. High anion gap metabolic acidosis is a form of metabolic acidosis characterized by a high anion gap (a medical value based on the concentrations of ions in a patient's serum). An anion gap is usually considered to be high if it is over 12 mEq/L. High anion gap metabolic acidosis is caused generally by acid produced by the body,. More rarely, high anion gap metabolic acidosis may be caused by ingesting methanol or overdosing on aspirin.[1][2] The Delta Ratio is a formula that can be used to assess elevated anion gap metabolic acidosis and to evaluate whether mixed acid base disorder (metabolic acidosis) is present. The list of agents that cause high anion gap metabolic acidosis is similar to but broader than the list of agents that cause a serum osmolal gap. Causes[edit] Causes include: The newest mnemonic was proposed in The Lancet reflecting current causes of anion gap metabolic acidosis:[3] G — glycols (ethylene glycol & propylene glycol) O — oxoproline, a metabolite of paracetamol L — L-lactate, the chemical responsible for lactic acidosis D — D-lactate M — methanol A — aspirin R — renal failure K — ketoacidosis, ketones generated from starvation, alcohol, and diabetic ketoacidosis The mnemonic MUDPILES is commonly used to remember the causes of increased anion gap metabolic acidosis.[4][5] M — Methanol U — Uremia (chronic kidney failure) D — Diabetic ketoacidosis P — Paracetamol, Propylene glycol (used as an inactive stabilizer in many medications; historically, the "P" also stood for Paraldehyde, though this substance is not commonly used today) I — Infectio Continue reading >>

If you may have swallowed a poison, such as wood alcohol, salicylate (in aspirin), and ethylene glycol (in antifreeze), your provider may test your blood for it. If your provider thinks you have ketoacidosis, you might need a urine dipstick test for ketone compounds. Ketoacidosis is a health emergency. Many things may affect your lab test results. These include the method each lab uses to do the test. Even if your test results are different from the normal value, you may not have a problem. To learn what the results mean for you, talk with your healthcare provider. Results are given in milliequivalents per liter (mEq/L). Normal results are 3 to 10mEq/L, although the normal level may vary from lab to lab. If your results are higher, it may mean that you have metabolic acidosis. Hypoalbuminemia means you haveless albumin protein than normal. If you have this condition, your expected normal result must be lower. The test requires a blood sample, which is drawn through a needle from a vein in your arm. Taking a blood sample with a needle carries risks that include bleeding, infection, bruising, or feeling dizzy. When the needle pricks your arm, you may feel a slight stinging sensation or pain. Afterward, the site may be slightly sore. Being dehydrated or retaining water in your body can affect your results. Antibiotics such as penicillin can also affect your results. You don't need to prepare for this test. But be sure your healthcare provider knows about all medicines, herbs, vitamins, and supplements you are taking. This includes medicines that don't need a prescription and any illicit drugs you may use. Continue reading >>

High Anion Gap Metabolic Acidosis

High Anion Gap Metabolic Acidosis

Go to: Introduction High anion gap metabolic acidosis (HAGMA) is a subcategory of acidosis of metabolic (i.e., non-respiratory) etiology. Differentiation of acidosis into a particular subtype, whether high anion gap metabolic acidosis or non-anion gap metabolic acidosis (NAGMA), aids in the determination of the etiology and hence appropriate treatment. Go to: Etiology Although there have been many broadly inclusive mnemonic devices for high anion gap metabolic acidosis, the use of "GOLD MARK" has gained popularity for its focus on causes common to the 21st century. Glycols (ethylene glycol, propylene glycol) Oxoproline (pyroglutamic acid, the toxic metabolite of excessive acetaminophen or paracetamol) L-Lactate (standard lactic acid seen in lactic acidosis) D-Lactate (exogenous lactic acid produced by gut bacteria) Methanol (this is inclusive of alcohols in general) Aspirin (salicylic acid) Ketones (diabetic, alcoholic and starvation ketosis) Of note, metformin has been omitted from this list due to a lack of evidence for metformin-induced lactic acidosis. In fact, a Cochrane review found substantial evidence that metformin was not a cause of lactic acidosis. The same could not be said of the older biguanide, phenformin, which does increase the incidence of lactic acidosis by approximately tenfold. Furthermore, the addition of massive rhabdomyolysis would be appropriate given the potentially large amounts of hydrogen ions released by muscle breakdown.

Anion Gap

Anion Gap

The anion gap is the difference between primary measured cations (sodium Na+ and potassium K+) and the primary measured anions (chloride Cl- and bicarbonate HCO3-) in serum. This test is most commonly performed in patients who present with altered mental status, unknown exposures, acute renal failure, and acute illnesses. [1] See the Anion Gap calculator. The reference range of the anion gap is 3-11 mEq/L The normal value for the serum anion gap is 8-16 mEq/L. However, there are always unmeasurable anions, so an anion gap of less than 11 mEq/L using any of the equations listed in Description is considered normal. For the urine anion gap, the most prominently unmeasured anion is ammonia. Healthy subjects typically have a gap of 0 to slightly normal (< 10 mEq/L). A urine anion gap of more than 20 mEq/L is seen in metabolic acidosis when the kidneys are unable to excrete ammonia (such as in renal tubular acidosis). If the urine anion gap is zero or negative but the serum AG is positive, the source is most likely gastrointestinal (diarrhea or vomiting). [2] Continue reading >>

Clinical Aspects Of The Anion Gap

Clinical Aspects Of The Anion Gap

The anion gap (AG) is a calculated parameter derived from measured serum/plasma electrolyte concentrations. The clinical value of this calculated parameter is the main focus of this article. Both increased and reduced anion gap have clinical significance, but the deviation from normal that has most clinical significance is increased anion gap associated with metabolic acidosis. This reflects the main clinical utility of the anion gap, which is to help in elucidating disturbances of acid-base balance. The article begins with a discussion of the concept of the anion gap, how it is calculated and issues surrounding the anion gap reference interval. CONCEPT OF THE ANION GAP - ITS DEFINITION AND CALCULATION Blood plasma is an aqueous (water) solution containing a plethora of chemical species including some that have a net electrical charge, the result of dissociation of salts and acids in the aqueous medium. Those that have a net positive charge are called cations and those with a net negative charge are called anions; collectively these electrically charged species are called ions. The law of electrochemical neutrality demands that, in common with all solutions, blood serum/plasma is electrochemically neutral so that the sum of the concentration of cations always equals the sum of the concentration of anions [1]. This immutable law is reflected in FIGURE 1, a graphic display of the concentration of the major ions normally present in plasma/serum. It is clear from this that quantitatively the most significant cation in plasma is sodium (Na+), and the most significant anions are chloride (Cl-) and bicarbonate HCO3-. The concentration of these three plasma constituents (sodium, chloride and bicarbonate) along with the cation potassium (K+) are routinely measured in the clinica Continue reading >>

Approach To The Adult With Metabolic Acidosis

Approach To The Adult With Metabolic Acidosis

INTRODUCTION On a typical Western diet, approximately 15,000 mmol of carbon dioxide (which can generate carbonic acid as it combines with water) and 50 to 100 mEq of nonvolatile acid (mostly sulfuric acid derived from the metabolism of sulfur-containing amino acids) are produced each day. Acid-base balance is maintained by pulmonary and renal excretion of carbon dioxide and nonvolatile acid, respectively. Renal excretion of acid involves the combination of hydrogen ions with urinary titratable acids, particularly phosphate (HPO42- + H+ —> H2PO4-), and ammonia to form ammonium (NH3 + H+ —> NH4+) [1]. The latter is the primary adaptive response since ammonia production from the metabolism of glutamine can be appropriately increased in response to an acid load [2]. Acid-base balance is usually assessed in terms of the bicarbonate-carbon dioxide buffer system: Dissolved CO2 + H2O <—> H2CO3 <—> HCO3- + H+ The ratio between these reactants can be expressed by the Henderson-Hasselbalch equation. By convention, the pKa of 6.10 is used when the dominator is the concentration of dissolved CO2, and this is proportional to the pCO2 (the actual concentration of the acid H2CO3 is very low): TI AU Garibotto G, Sofia A, Robaudo C, Saffioti S, Sala MR, Verzola D, Vettore M, Russo R, Procopio V, Deferrari G, Tessari P To evaluate the effects of chronic metabolic acidosis on protein dynamics and amino acid oxidation in the human kidney, a combination of organ isotopic ((14)C-leucine) and mass-balance techniques in 11 subjects with normal renal function undergoing venous catheterizations was used.
