Metformin-related Lactic Acidosis: Case Report - Sciencedirect

Metformin-related Lactic Acidosis: Case Report - Sciencedirect

Open Access funded by Sociedad Colombiana de Anestesiologa y Reanimacin Lactic acidosis is defined as the presence of pH <7.35, blood lactate >2.0mmol/L and PaCO2 <42mmHg. However, the definition of severe lactic acidosis is controversial. The primary cause of severe lactic acidosis is shock. Although rare, metformin-related lactic acidosis is associated with a mortality as high as 50%. The treatment for metabolic acidosis, including lactic acidosis, may be specific or general, using sodium bicarbonate, trihydroxyaminomethane, carbicarb or continuous haemodiafiltration. The successful treatment of lactic acidosis depends on the control of the aetiological source. Intermittent or continuous renal replacement therapy is perfectly justified, shock being the argument for deciding which modality to use. We report a case of a male patient presenting with metformin poisoning as a result of attempted suicide, who developed lactic acidosis and multiple organ failure. The critical success factor was treatment with continuous haemodiafiltration. Definimos acidosis lctica en presencia de pH <7.35, lactato en sangre >2.0mmol/L y PaCO2 <42mmHg. Por otro lado, la definicin de acidosis lctica grave es controvertida. La causa principal de acidosis lctica grave es el estado de choque. La acidosis lctica por metformina es rara pero alcanza mortalidad del 50%. La acidosis metablica incluyendo a la acidosis lctica puede recibir tratamiento especfico o tratamiento general con bicarbonato de sodio, trihidroxiaminometano, carbicarb o hemodiafiltracin continua. El xito del tratamiento de la acidosis lctica yace en el control de la fuente etiolgica; la terapia de reemplazo renal intermitente o continua est perfectamente justificada, donde el argumento para decidir cul utilizar ser el estado de Continue reading >>

Grain Overload In Ruminants

Grain Overload In Ruminants

(Lactic acidosis, Carbohydrate engorgement, Rumenitis) By Peter D. Constable, BVSc (Hons), MS, PhD, DACVIM, Dean, College of Veterinary Medicine, University of Illinois Grain overload is an acute disease of ruminants that is characterized by rumen hypomotility to atony, dehydration, acidemia, diarrhea, depression, incoordination, collapse, and in severe cases, death. The disease is most common in cattle that accidentally gain access to large quantities of readily digestible carbohydrates, particularly grain. Grain overload also is common in feedlot cattle when they are introduced to heavy grain diets too quickly. Wheat, barley, and corn are the most readily digestible grains; oats are less digestible. Less common causes include engorgement with apples, grapes, bread, batters dough, sugar beets, potatoes, mangels, or sour wet brewers grain that was incompletely fermented in the brewery. The amount of feed required to produce acute illness depends on the kind of grain, previous experience of the animal with that grain, the nutritional status and condition of the animal, and the nature of the ruminal microflora. Adult cattle accustomed to heavy grain diets may consume 3045 lb (1520 kg) of grain and develop only moderate illness, whereas others may become acutely ill and die after eating 20 lb (10 kg) of grain. Ingestion of toxic amounts of highly fermentable carbohydrates is followed within 26 hr by a change in the microbial population in the rumen. The number of gram-positive bacteria (such as Streptococcus bovis) increases markedly, which results in the production of large quantities of lactic acid. The rumen pH falls to 5, which destroys protozoa, cellulolytic organisms, and lactate-utilizing organisms, and impairs rumen motility. The low pH allows the lactobacilli to Continue reading >>

Metabolic Acidosis Treatment & Management: Approach Considerations, Type 1 Renal Tubular Acidosis, Type 2 Renal Tubular Acidosis

Metabolic AcidosisTreatment & Management Author: Christie P Thomas, MBBS, FRCP, FASN, FAHA; Chief Editor: Vecihi Batuman, MD, FASN more... Treatment of acute metabolic acidosis by alkali therapy is usually indicated to raise and maintain the plasma pH to greater than 7.20. In the following two circumstances this is particularly important. When the serum pH is below 7.20, a continued fall in the serum HCO3- level may result in a significant drop in pH. This is especially true when the PCO2 is close to the lower limit of compensation, which in an otherwise healthy young individual is approximately 15 mm Hg. With increasing age and other complicating illnesses, the limit of compensation is likely to be less. A further small drop in HCO3- at this point thus is not matched by a corresponding fall in PaCO2, and rapid decompensation can occur. For example, in a patient with metabolic acidosis with a serum HCO3- level of 9 mEq/L and a maximally compensated PCO2 of 20 mm Hg, a drop in the serum HCO3- level to 7 mEq/L results in a change in pH from 7.28 to 7.16. A second situation in which HCO3- correction should be considered is in well-compensated metabolic acidosis with impending respiratory failure. As metabolic acidosis continues in some patients, the increased ventilatory drive to lower the PaCO2 may not be sustainable because of respiratory muscle fatigue. In this situation, a PaCO2 that starts to rise may change the plasma pH dramatically even without a significant further fall in HCO3-. For example, in a patient with metabolic acidosis with a serum HCO3- level of 15 and a compensated PaCO2 of 27 mm Hg, a rise in PaCO2 to 37 mm Hg results in a change in pH from 7.33 to 7.20. A further rise of the PaCO2 to 43 mm Hg drops the pH to 7.14. All of this would have occurred whi Continue reading >>

Urine Ammonium, Metabolic Acidosis And Progression Of Chronic Kidney Disease

Urine Ammonium, Metabolic Acidosis And Progression Of Chronic Kidney Disease

Urine Ammonium, Metabolic Acidosis and Progression of Chronic Kidney Disease Pourafshar N.a · Pourafshar S.a · Soleimani M.b,c aDepartment of Medicine at University of Virginia, Charlottesville, VA, USA bDepartment of Medicine, University of Cincinnati, Cincinnati, OH, USA cDepartment of Medicine Services, Veterans Medical Center, Cincinnati, OH, USA The metabolism of a typical Western diet generates 50–100 mEq of acid (H+) per day, which must be excreted in the urine for the systemic acid-base to remain in balance. The 2 major mechanisms that are responsible for the renal elimination of daily acid under normal conditions are ammonium (NH4+) excretion and titratable acidity. In the presence of systemic acidosis, ammonium excretion is intensified and becomes the crucial mechanism for the elimination of acid. The impairment in NH4+ excretion is therefore associated with reduced acid excretion, which causes excess accumulation of acid in the body and consequently results in metabolic acidosis. Chronic kidney disease (CKD) is associated with the impairment in acid excretion and precipitation of metabolic acidosis, which has an adverse effect on the progression of CKD. Recent studies suggest that the progressive decline in renal ammonium excretion in CKD is an important determinant of the ensuing systemic metabolic acidosis and is an independent factor for predicting the worsening of kidney function. While these studies have been primarily performed in hypertensive individuals with CKD, a closer look at renal NH4+ excretion in non-hypertensive individuals with CKD is warranted to ascertain its role in the progression of kidney disease. The elimination of acid (H+) by kidney is the most crucial step in the maintenance of systemic acid-base homeostasis [ 1 , 2 ]. The rena Continue reading >>

Diabetic Ketoacidosis

Diabetic Ketoacidosis

Professor of Pediatric Endocrinology University of Khartoum, Sudan Introduction DKA is a serious acute complications of Diabetes Mellitus. It carries significant risk of death and/or morbidity especially with delayed treatment. The prognosis of DKA is worse in the extremes of age, with a mortality rates of 5-10%. With the new advances of therapy, DKA mortality decreases to > 2%. Before discovery and use of Insulin (1922) the mortality was 100%. Epidemiology DKA is reported in 2-5% of known type 1 diabetic patients in industrialized countries, while it occurs in 35-40% of such patients in Africa. DKA at the time of first diagnosis of diabetes mellitus is reported in only 2-3% in western Europe, but is seen in 95% of diabetic children in Sudan. Similar results were reported from other African countries . Consequences The latter observation is annoying because it implies the following: The late diagnosis of type 1 diabetes in many developing countries particularly in Africa. The late presentation of DKA, which is associated with risk of morbidity & mortality Death of young children with DKA undiagnosed or wrongly diagnosed as malaria or meningitis. Pathophysiology Secondary to insulin deficiency, and the action of counter-regulatory hormones, blood glucose increases leading to hyperglycemia and glucosuria. Glucosuria causes an osmotic diuresis, leading to water & Na loss. In the absence of insulin activity the body fails to utilize glucose as fuel and uses fats instead. This leads to ketosis. Pathophysiology/2 The excess of ketone bodies will cause metabolic acidosis, the later is also aggravated by Lactic acidosis caused by dehydration & poor tissue perfusion. Vomiting due to an ileus, plus increased insensible water losses due to tachypnea will worsen the state of dehydr Continue reading >>

Metabolic Acidosis

Metabolic Acidosis

Metabolic acidosis is a condition that occurs when the body produces excessive quantities of acid or when the kidneys are not removing enough acid from the body. If unchecked, metabolic acidosis leads to acidemia, i.e., blood pH is low (less than 7.35) due to increased production of hydrogen ions by the body or the inability of the body to form bicarbonate (HCO3−) in the kidney. Its causes are diverse, and its consequences can be serious, including coma and death. Together with respiratory acidosis, it is one of the two general causes of acidemia. Terminology : Acidosis refers to a process that causes a low pH in blood and tissues. Acidemia refers specifically to a low pH in the blood. In most cases, acidosis occurs first for reasons explained below. Free hydrogen ions then diffuse into the blood, lowering the pH. Arterial blood gas analysis detects acidemia (pH lower than 7.35). When acidemia is present, acidosis is presumed. Signs and symptoms[edit] Symptoms are not specific, and diagnosis can be difficult unless the patient presents with clear indications for arterial blood gas sampling. Symptoms may include chest pain, palpitations, headache, altered mental status such as severe anxiety due to hypoxia, decreased visual acuity, nausea, vomiting, abdominal pain, altered appetite and weight gain, muscle weakness, bone pain, and joint pain. Those in metabolic acidosis may exhibit deep, rapid breathing called Kussmaul respirations which is classically associated with diabetic ketoacidosis. Rapid deep breaths increase the amount of carbon dioxide exhaled, thus lowering the serum carbon dioxide levels, resulting in some degree of compensation. Overcompensation via respiratory alkalosis to form an alkalemia does not occur. Extreme acidemia leads to neurological and cardia Continue reading >>

New York, NY: McGraw-Hill, 2012, Systemic arterial pH is maintained between 7.35 and 7.45 by extracellular and intracellular chemical buffering together with respiratory and renal regulatory mechanisms. The control of arterial CO2 tension (Paco2) by the central nervous system (CNS) and respiratory systems and the control of the plasma bicarbonate by the kidneys stabilize the arterial pH by excretion or retention of acid or alkali. The metabolic and respiratory components that regulate systemic pH are described by the Henderson-Hasselbalch equation: Under most circumstances, CO2 production and excretion are matched, and the usual steady-state Paco2 is maintained at 40 mmHg. Underexcretion of CO2 produces hypercapnia, and overexcretion causes hypocapnia. Nevertheless, production and excretion are again matched at a new steady-state Paco2. Therefore, the Paco2 is regulated primarily by neural respiratory factors and is not subject to regulation by the rate of CO2 production. Hypercapnia is usually the result of hypoventilation rather than of increased CO2 production. Increases or decreases in Paco2 represent de Continue reading >>

Subacute Ruminal Acidosis

Subacute Ruminal Acidosis

(Chronic ruminal acidosis, Subclinical ruminal acidosis) By Ingrid Lorenz, DMV, DMVH, DECBHM, Lecturer in Bovine Medicine, School of Agriculture, Food Science and Veterinary Medicine, University College Dublin Ruminant animals are adapted to digest and metabolize predominantly forage diets; however, growth rates and milk production are increased substantially when ruminants consume high-grain diets. One consequence of feeding excessive amounts of rapidly fermentable carbohydrates in conjunction with inadequate fiber to ruminants is subacute ruminal acidosis, which is characterized by periods of low ruminal pH that resolve without treatment and is rarely diagnosed. Dairy cows, feedlot cattle, and feedlot sheep are at risk of developing this condition. Ruminal pH fluctuates considerably during a 24hr period (typically between 0.51 pH units) and is determined by the dynamic balance between the intake of fermentable carbohydrates, buffering capacity of the rumen, and rate of acid absorption from the rumen. In general, subacute ruminal acidosis is caused by ingestion of diets high in rapidly fermentable carbohydrates and/or deficient in physically active fiber. Subacute ruminal acidosis is most commonly defined as repeatedly occurring prolonged periods of depression of the ruminal pH to values between 5.6 and 5.2. The low ruminal pH is caused by excessive accumulation of volatile fatty acids (VFAs) without persistent lactic acid accumulation and is restored to normal by the animals own physiologic responses. The ability of the rumen to rapidly absorb organic acids contributes greatly to the stability of ruminal pH. It is rarely difficult for peripheral tissues to utilize VFAs already absorbed from the rumen; however, absorption of these VFAs from the rumen can be an importa Continue reading >>

Metabolic Acidosis Nursing Management And Interventions - Nurseslabs

Metabolic Acidosisis an acid-base imbalance resulting from excessive absorption or retention of acid or excessive excretion of bicarbonate produced by an underlying pathologic disorder. Symptoms result from the bodys attempts to correct the acidotic condition through compensatory mechanisms in the lungs , kidneys and cells. Metabolic acidosis is characterized by normal or high anion gap situations. If the primary problem is direct loss of bicarbonate, gain of chloride, or decreased ammonia production, the anion gap is within normal limits. If the primary problem is the accumulation of organic anions (such as ketones or lactic acid), the condition is known as high anion gap acidosis. Compensatory mechanisms to correct this imbalance include an increase in respirations to blow off excess CO2, an increase in ammonia formation, and acid excretion (H+) by the kidneys, with retention of bicarbonate and sodium . High anion gap acidosis occurs in diabetic ketoacidosis ; severe malnutrition or starvation, alcoholic lactic acidosis; renal failure; high-fat, low-carbohydrate diets/lipid administration; poisoning, e.g., salicylate intoxication (after initial stage); paraldehyde intoxication; and drug therapy, e.g., acetazolamide (Diamox), NH4Cl. Normal anion gap acidosis is associated with loss of bicarbonate form the body, as may occur in renal tubular acidosis, hyperalimentation, vomiting/ diarrhea , small-bowel/pancreatic fistulas, and ileostomy and use of IV sodium chloride in presence of preexisting kidney dysfunction, acidifying drugs (e.g., ammonium chloride). This condition does not occur in isolation but rather is a complication of a broader problem that may require inpatient care in a medical-surgical or subacute unit. Use of carbonic anhydrase inhibitors or anion-exchan Continue reading >>

Metabolic Acidosis: Causes, Symptoms, And Treatment

Metabolic Acidosis: Causes, Symptoms, And Treatment

The Terrible Effects of Acid Acid corrosion is a well-known fact. Acid rain can peel the paint off of a car. Acidifying ocean water bleaches and destroys coral reefs. Acid can burn a giant hole through metal. It can also burn holes, called cavities, into your teeth. I think I've made my point. Acid, regardless of where it's at, is going to hurt. And when your body is full of acid, then it's going to destroy your fragile, soft, internal organs even more quickly than it can destroy your bony teeth and chunks of thick metal. What Is Metabolic Acidosis? The condition that fills your body with proportionately too much acid is known as metabolic acidosis. Metabolic acidosis refers to a physiological state characterized by an increase in the amount of acid produced or ingested by the body, the decreased renal excretion of acid, or bicarbonate loss from the body. Metabolism is a word that refers to a set of biochemical processes within your body that produce energy and sustain life. If these processes go haywire, due to disease, then they can cause an excess production of hydrogen (H+) ions. These ions are acidic, and therefore the level of acidity in your body increases, leading to acidemia, an abnormally low pH of the blood, <7.35. The pH of the blood mimics the overall physiological state in the body. In short, a metabolic process is like a power plant producing energy. If a nuclear power plant goes haywire for any reason, then we know what the consequences will be: uncontrolled and excessive nuclear energetic reactions leading to the leakage of large amounts of radioactive material out into the environment. In our body, this radioactive material is acid (or hydrogen ions). Acidemia can also occur if the kidneys are sick and they do not excrete enough hydrogen ions out of th Continue reading >>
