A pathologic condition of acid accumulation or depletion of base in the body. The two main types are RESPIRATORY ACIDOSIS and metabolic acidosis, due to metabolic acid build up.
Acidosis caused by accumulation of lactic acid more rapidly than it can be metabolized. It may occur spontaneously or in association with diseases such as DIABETES MELLITUS; LEUKEMIA; or LIVER FAILURE.
Respiratory retention of carbon dioxide. It may be chronic or acute.
A group of genetic disorders of the KIDNEY TUBULES characterized by the accumulation of metabolically produced acids with elevated plasma chloride, hyperchloremic metabolic ACIDOSIS. Defective renal acidification of URINE (proximal tubules) or low renal acid excretion (distal tubules) can lead to complications such as HYPOKALEMIA, hypercalcinuria with NEPHROLITHIASIS and NEPHROCALCINOSIS, and RICKETS.
The balance between acids and bases in the BODY FLUIDS. The pH (HYDROGEN-ION CONCENTRATION) of the arterial BLOOD provides an index for the total body acid-base balance.
Inorganic salts that contain the -HCO3 radical. They are an important factor in determining the pH of the blood and the concentration of bicarbonate ions is regulated by the kidney. Levels in the blood are an index of the alkali reserve or buffering capacity.
The normality of a solution with respect to HYDROGEN ions; H+. It is related to acidity measurements in most cases by pH = log 1/2[1/(H+)], where (H+) is the hydrogen ion concentration in gram equivalents per liter of solution. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)
A white, crystalline powder that is commonly used as a pH buffering agent, an electrolyte replenisher, systemic alkalizer and in topical cleansing solutions.
A pathological condition that removes acid or adds base to the body fluids.
An acidifying agent that has expectorant and diuretic effects. Also used in etching and batteries and as a flux in electroplating.
A mitochondrial disorder characterized by focal or generalized seizures, episodes of transient or persistent neurologic dysfunction resembling strokes, and ragged-red fibers on muscle biopsy. Affected individuals tend to be normal at birth through early childhood, then experience growth failure, episodic vomiting, and recurrent cerebral insults resulting in visual loss and hemiparesis. The cortical lesions tend to occur in the parietal and occipital lobes and are not associated with vascular occlusion. VASCULAR HEADACHE is frequently associated and the disorder tends to be familial. (From Joynt, Clinical Neurology, 1992, Ch56, p117)

Proteins that cotransport sodium ions and bicarbonate ions across cellular membranes.
Chemical compounds which yield hydrogen ions or protons when dissolved in water, whose hydrogen can be replaced by metals or basic radicals, or which react with bases to form salts and water (neutralization). An extension of the term includes substances dissolved in media other than water. (Grant & Hackh's Chemical Dictionary, 5th ed)
A strong corrosive acid that is commonly used as a laboratory reagent. It is formed by dissolving hydrogen chloride in water. GASTRIC ACID is the hydrochloric acid component of GASTRIC JUICE.
Abnormally low potassium concentration in the blood. It may result from potassium loss by renal secretion or by the gastrointestinal route, as by vomiting or diarrhea. It may be manifested clinically by neuromuscular disorders ranging from weakness to paralysis, by electrocardiographic abnormalities (depression of the T wave and elevation of the U wave), by renal disease, and by gastrointestinal disorders. (Dorland, 27th ed)

It is characterized clinically by electrocardiographic abnormalities (elevated T waves and depressed P waves, and eventually by atrial asystole). In severe cases, weakness and flaccid paralysis may occur. (Dorland, 27th ed)
A hereditary or acquired form of generalized dysfunction of the PROXIMAL KIDNEY TUBULE without primary involvement of the KIDNEY GLOMERULUS. It is usually characterized by the tubular wasting of nutrients and salts (GLUCOSE; AMINO ACIDS; PHOSPHATES; and BICARBONATES) resulting in HYPOKALEMIA; ACIDOSIS; HYPERCALCIURIA; and PROTEINURIA.

A condition characterized by calcification of the renal tissue itself. It is usually seen in distal RENAL TUBULAR ACIDOSIS with calcium deposition in the DISTAL KIDNEY TUBULES and the surrounding interstitium. Nephrocalcinosis causes RENAL INSUFFICIENCY.
The first stomach of ruminants. It lies on the left side of the body, occupying the whole of the left side of the abdomen and even stretching across the median plane of the body to the right side. It is capacious, divided into an upper and a lower sac, each of which has a blind sac at its posterior extremity. The rumen is lined by mucous membrane containing no digestive glands, but mucus-secreting glands are present in large numbers. Coarse, partially chewed food is stored and churned in the rumen until the animal finds circumstances convenient for rumination. When this occurs, little balls of food are regurgitated through the esophagus into the mouth, and are subjected to a second more thorough mastication, swallowed, and passed on into other parts of the compound stomach.

Decreased lactic acidosis and anemia after transfusion of o-raffinose cross-linked and polymerized hemoglobin in severe murine malaria. (1/290)

Severe anemia is a major cause of death in falciparum malaria. Blood transfusion increases survival in humans and in animal models of this disease. Because of logistic constraints and viral contamination of the blood supply, transfusions are frequently not practical in endemic regions. Modified hemoglobin is an effective O2 carrier in hemorrhagic shock. It is free of infectious contamination, may not require refrigeration, and because of its nitric oxide scavenging and small size, may have pharmacologic benefits in malaria. The effects of transfusions of modified hemoglobin in rats with high-grade parasitemia were evaluated. Modified hemoglobin decreased lactic acidosis and corrected anemia as well as transfusions with red blood cells; these findings may correlate with improved survival and suggest a possible proerythropoietic effect. Further study of this novel therapy is warranted.  (+info)

Incidence of lactic acidosis in metformin users. (2/290)

OBJECTIVE: The purpose of this study was to determine the incidence of lactic acidosis in a geographically defined population of metformin users. RESEARCH DESIGN AND METHODS: The study was based on a historical cohort from the Saskatchewan Health administrative databases. Individuals with a metformin prescription dispensed between 1980 and 1995 inclusive were eligible for the cohort. Person-years of exposure were calculated. Cases were defined by hospital discharge with a diagnosis of acidosis (International Classification of Diseases, Ninth Revision code: 276.2) and confirmation by chart review of a blood lactate level > or = 5 mmol/l. Death registrations of individuals dying within 120 days of a metformin prescription were also reviewed. RESULTS: During the study period, 11,797 residents received one or more metformin prescriptions, resulting in 22,296 person-years of exposure. There were 10 subjects who had hospital discharges with a diagnosis of acidosis. However, primary record review revealed only two cases with laboratory findings of elevated blood lactate levels, for an incidence rate of 9 cases per 100,000 person-years of metformin exposure. In both cases, other factors besides metformin could have contributed to the lactic acidosis. No additional cases were found on review of death registrations. CONCLUSIONS: From 1980 through 1995, the incidence rate of lactic acidosis was 9 per 100,000 person-years (95% CI 0-21) in patients dispensed metformin in Saskatchewan, Canada. This incidence rate was derived from a population with complete ascertainment of hospitalizations and deaths associated with lactic acidosis in metformin users. It is similar to previously published rates based on passive reporting of cases, and it is well below the lactic acidosis rate of 40-64 per 100,000 patient-years in patients prescribed phenformin.  (+info)

Nuclear DNA origin of mitochondrial complex I deficiency in fatal infantile lactic acidosis evidenced by transnuclear complementation of cultured fibroblasts. (3/290)

We have studied complex I (NADH-ubiquinone reductase) defects of the mitochondrial respiratory chain in 2 infants who died in the neonatal period from 2 different neurological forms of severe neonatal lactic acidosis. Specific and marked decrease in complex I activity was documented in muscle, liver, and cultured skin fibroblasts. Biochemical characterization and study of the genetic origin of this defect were performed using cultured fibroblasts. Immunodetection of 6 nuclear DNA-encoded (20, 23, 24, 30, 49, and 51 kDa) and 1 mitochondrial DNA-encoded (ND1) complex I subunits in fibroblast mitochondria revealed 2 distinct patterns. In 1 patient, complex I contained reduced amounts of the 24- and 51-kDa subunits and normal amounts of all the other investigated subunits. In the second patient, amounts of all the investigated subunits were severely decreased. The data suggest partial or extensive impairment of complex I assembly in both patients. Cell fusion experiments between 143B206 rho degrees cells, fully depleted of mitochondrial DNA, and fibroblasts from both patients led to phenotypic complementation of the complex I defects in mitochondria of the resulting cybrid cells. These results indicate that the complex I defects in the 2 reported cases are due to nuclear gene mutations.  (+info)

Blood lactate accumulation and muscle deoxygenation during incremental exercise. (4/290)

Near-infrared spectroscopy (NIRS) could allow insights into controversial issues related to blood lactate concentration ([La](b)) increases at submaximal workloads (). We combined, on five well-trained subjects [mountain climbers; peak O(2) consumption (VO(2peak)), 51.0 +/- 4.2 (SD) ml. kg(-1). min(-1)] performing incremental exercise on a cycle ergometer (30 W added every 4 min up to voluntary exhaustion), measurements of pulmonary gas exchange and earlobe [La](b) with determinations of concentration changes of oxygenated Hb (Delta[O(2)Hb]) and deoxygenated Hb (Delta[HHb]) in the vastus lateralis muscle, by continuous-wave NIRS. A "point of inflection" of [La](b) vs. was arbitrarily identified at the lowest [La](b) value which was >0.5 mM lower than that obtained at the following. Total Hb volume (Delta[O(2)Hb + HHb]) in the muscle region of interest increased as a function of up to 60-65% of VO(2 peak), after which it remained unchanged. The oxygenation index (Delta[O(2)Hb - HHb]) showed an accelerated decrease from 60- 65% of VO(2 peak). In the presence of a constant total Hb volume, the observed Delta[O(2)Hb - HHb] decrease indicates muscle deoxygenation (i.e., mainly capillary-venular Hb desaturation). The onset of muscle deoxygenation was significantly correlated (r(2) = 0.95; P < 0.01) with the point of inflection of [La](b) vs., i.e., with the onset of blood lactate accumulation. Previous studies showed relatively constant femoral venous PO(2) levels at higher than approximately 60% of maximal O(2) consumption. Thus muscle deoxygenation observed in the present study from 60-65% of VO(2 peak) could be attributed to capillary-venular Hb desaturation in the presence of relatively constant capillary-venular PO(2) levels, as a consequence of a rightward shift of the O(2)Hb dissociation curve determined by the onset of lactic acidosis.  (+info)

Hypoxia-activated apoptosis of cardiac myocytes requires reoxygenation or a pH shift and is independent of p53. (5/290)

Ischemia and reperfusion activate cardiac myocyte apoptosis, which may be an important feature in the progression of ischemic heart disease. The relative contributions of ischemia and reperfusion to apoptotic signal transduction have not been established. We report here that severe chronic hypoxia alone does not cause apoptosis of cardiac myocytes in culture. When rapidly contracting cardiac myocytes were exposed to chronic hypoxia, apoptosis occurred only when there was a decrease in extracellular pH ([pH](o)). Apoptosis did not occur when [pH](o) was neutralized. Addition of acidic medium from hypoxic cultures or exogenous lactic acid stimulated apoptosis in aerobic myocytes. Hypoxia-acidosis-mediated cell death was independent of p53: equivalent apoptosis occurred in cardiac myocytes isolated from wild-type and p53 knockout mice, and hypoxia caused no detectable change in p53 abundance or p53-dependent transcription. Reoxygenation of hypoxic cardiac myocytes induced apoptosis in 25-30% of the cells and was also independent of p53 by the same criteria. Finally, equivalent levels of apoptosis, as demonstrated by DNA fragmentation, were induced by ischemia-reperfusion, but not by ischemia alone, of Langendorff-perfused hearts from wild-type and p53 knockout mice. We conclude that acidosis, reoxygenation, and reperfusion, but not hypoxia (or ischemia) alone, are strong stimuli for programmed cell death that is substantially independent of p53.  (+info)

Actively phosphorylating mitochondria are more resistant to lactic acidosis than inactive mitochondria. (6/290)

Oxidative phosphorylation of isolated rat skeletal muscle mitochondria after exposure to lactic acidosis in either phosphorylating or nonphosphorylating states has been evaluated. Mitochondrial respiration and transmembrane potential (DeltaPsi(m)) were measured with pyruvate and malate as the substrates. The addition of lactic acid decreased the pH of the reaction medium from 7.5 to 6.4. When lactic acid was added to nonphosphorylating mitochondria, the subsequent maximal ADP-stimulated respiration decreased by 27% compared with that under control conditions (P < 0.05), and the apparent Michaelis-Menten constant (K(m)) for ADP decreased to 10 microM vs. 20 microM (P < 0.05) in controls. In contrast, maximal respiration and ADP sensitivity were not affected when mitochondria were exposed to acidosis during active phosphorylation in state 3. Acidosis significantly increased mitochondrial oxygen consumption in state 4 (post-state 3), irrespective of when acidosis was induced. This effect of acidosis was attenuated in the presence of oligomycin. The addition of lactic acid during state 4 respiration decreased DeltaPsi(m) by 19%. The ratio between added ADP and consumed oxygen (P/O) was close to the theoretical value of 3 in all conditions. The addition of potassium lactate during state 3 (i.e., medium pH unchanged) had no effect on the parameters measured. It is concluded that lactic acidosis has different effects when induced on nonphosphorylating vs. actively phosphorylating mitochondria. On the basis of these results, we suggest that the influence of lactic acidosis on muscle aerobic energy production depends on the physiological conditions at the onset of acidity.  (+info)

A novel deficiency of mitochondrial ATPase of nuclear origin. (7/290)

We report a new type of fatal mitochondrial disorder caused by selective deficiency of mitochondrial ATP synthase (ATPase). A hypotrophic newborn from a consanguineous marriage presented severe lactic acidosis, cardiomegaly and hepatomegaly and died from heart failure after 2 days. The activity of oligomycin-sensitive ATPase was only 31-34% of the control, both in muscle and heart, but the activities of cytochrome c oxidase, citrate synthase and pyruvate dehydrogenase were normal. Electrophoretic and western blot analysis revealed selective reduction of ATPase complex but normal levels of the respiratory chain complexes I, III and IV. The same selective deficiency of ATPase was found in cultured skin fibroblasts which showed similar decreases in ATPase content, ATPase hydrolytic activity and level of substrate-dependent ATP synthesis (20-25, 18 and 29-33% of the control, respectively). Pulse-chase labelling of patient fibroblasts revealed low incorporation of [(35)S]methionine into assembled ATPase complexes, but increased incorporation into immunoprecipitated ATPase subunit beta, which had a very short half-life. In contrast, no difference was found in the size and subunit composition of the assembled and newly produced ATPase complex. Transmitochondrial cybrids prepared from enucleated fibroblasts of the patient and rho degrees cells derived from 143B. TK(-)human osteosarcoma cells fully restored the ATPase activity, ATP synthesis and ATPase content, when compared with control cybrids. Likewise, the pattern of [(35)S]methionine labelling of ATPase was found to be normal in patient cybrids. We conclude that the generalized deficiency of mitochondrial ATPase described is of nuclear origin and is caused by altered biosynthesis of the enzyme.  (+info)

A missense mutation of cytochrome oxidase subunit II causes defective assembly and myopathy. (8/290)

We report the first missense mutation in the mtDNA gene for subunit II of cytochrome c oxidase (COX). The mutation was identified in a 14-year-old boy with a proximal myopathy and lactic acidosis. Muscle histochemistry and mitochondrial respiratory-chain enzymology demonstrated a marked reduction in COX activity. Immunohistochemistry and immunoblot analyses with COX subunit-specific monoclonal antibodies showed a pattern suggestive of a primary mtDNA defect, most likely involving CO II, for COX subunit II (COX II). mtDNA-sequence analysis demonstrated a novel heteroplasmic T-->A transversion at nucleotide position 7,671 in CO II. This mutation changes a methionine to a lysine residue in the middle of the first N-terminal membrane-spanning region of COX II. The immunoblot studies demonstrated a severe reduction in cross-reactivity, not only for COX II but also for the mtDNA-encoded subunit COX III and for nuclear-encoded subunits Vb, VIa, VIb, and VIc. Steady-state levels of the mtDNA-encoded subunit COX I showed a mild reduction, but spectrophotometric analysis revealed a dramatic decrease in COX I-associated heme a3 levels. These observations suggest that, in the COX protein, a structural association of COX II with COX I is necessary to stabilize the binding of heme a3 to COX I.  (+info)

Metformin has been widely used as a first-line agent to treat type 2 diabetes mellitus. Lactic acidosis is a rare but serious adverse effect in patients treated with metformin. Recent studies noted a correlation between metformin accumulation and lactic acidosis. Continuous renal replacement therapy for the treatment of metformin-associated lactic acidosis has been documented in some case reports; however, there is currently no specific treatment for metformin-associated lactic acidosis. A 70-year-old Japanese woman with type 2 diabetes mellitus presented to an emergency room with metformin-associated lactic acidosis. She was found to be hypotensive and laboratory examinations revealed severe lactic acidosis: pH 6.618, partial pressure of carbon dioxide in arterial blood 17.3 mmHg, bicarbonate 1.7 mmol/L, and lactate 18 mmol/L. Severe acidemia persisted despite supportive care including intravenously administered fluids, sodium bicarbonate, antibiotics, and vasopressors. Continuous renal replacement
Metformin is recommended as the treatment of choice in patients with type 2 diabetes mellitus because of its efficacy, general tolerability and low cost.. Recent guidelines have extended the use of metformin to patients with Chronic Kidney Disease (CKD) up to stage III. However, in the recent literature, cases of MALA (metformin-associated lactic acidosis) are increasingly reported. MALA is the most dangerous side effect of the drug, with an incidence rate of 2-9 cases per 100000 person-years of exposure.. We report on two patients with accidental metformin overdose, severe lactic acidosis and acute kidney injury. In both cases, the usual dose of metformin was inappropriate with respect to the level of kidney dysfunction (CKD stage III). As both patients met the criteria for renal replacement therapy in metformin poisoning, they were treated effectively with sustained low-efficiency dialysis until normalization of serum lactate and bicarbonate values. Clinical status and kidney function improved ...
Lactic acidosis is a rare but potentially serious adverse effect of metformin therapy. Might continuous renal replacement therapy be advantageous in metformin-associated lactic acidosis?
Metformin is the most commonly used oral antihyperglycemic drug in type 2 diabetes. Metformin-associated lactic acidosis (MALA) is a rare but severe
Metformin associated lactic acidosis (MALA) may complicate metformin therapy, particularly if metformin accumulates due to renal dysfunction. Profound lactic acidosis (LA) generally predicts poor outcome. We aimed to determine if MALA differs in outcome from LA of other origin (LAOO). We conducted a retrospective analysis of all patients admitted with LA to our medical ICU of a tertiary referral center during a 5-year period. MALA patients and LAOO patients were compared with respect to parameters of acid-base balance, serum creatinine, hospital outcome, Simplified Acute Physiology Score II (SAPS II) and Sequential Organ Failure Assessment (SOFA) score, using Pearsons Chi-square or the Mann-Whitney U-test. Of 197 patients admitted with LA, 10 had been diagnosed with MALA. With MALA, median arterial blood pH was significantly lower (6.78 [range 6.5 to 6.94]) and serum lactate significantly higher (18.7 ± 5.3 mmol/L) than with LAOO (pH 7.20 [range 6.46 to 7.35], mean serum lactate 11.2 ± 6.1 mmol/L).
WARNING: LACTIC ACIDOSIS. Postmarketing cases of metformin-associated lactic acidosis have resulted in death, hypothermia, hypotension, and resistant bradyarrhythmias. The onset of metformin- associated lactic acidosis is often subtle, accompanied only by nonspecific symptoms such as malaise, myalgias, respiratory distress, somnolence, and abdominal pain. Metformin-associated lactic acidosis was characterized by elevated blood lactate levels (,5 mmol/Liter), anion gap acidosis (without evidence of ketonuria or ketonemia), an increased lactate/pyruvate ratio; and metformin plasma levels generally ,5 mcg/mL (see PRECAUTIONS).. Risk factors for metformin-associated lactic acidosis include renal impairment, concomitant use of certain drugs (e.g. carbonic anhydrase inhibitors such as topiramate), age 65 years old or greater, having a radiological study with contrast, surgery and other procedures, hypoxic states (e.g., acute congestive heart failure), excessive alcohol intake, and hepatic ...
Type B lactic acidosis may be due to metabolic causes (eg, diabetes, ketoacidosis, liver disease, kidney disease, infection, leukemia, or lymphoma) or toxins (eg, ethanol, methanol, salicylates, isoniazid, or metformin). Propylene glycol can cause lactic acidosis from decreased liver metabolism; it is used as a vehicle for intravenous drugs, such as nitroglycerin, etomidate, and diazepam. Parenteral nutrition without thiamine causes severe refractory lactic acidosis from deranged pyruvate metabolism. Patients with short bowel syndrome may develop d-lactic acidosis with encephalopathy due to carbohydrate malabsorption and subsequent fermentation by colonic bacteria. Nucleoside analog reverse transcriptase inhibitors can cause type B lactic acidosis due to mitochondrial toxicity. ...

N2 - The incidence of nucleoside analogue-related lactic acidosis has been estimated in 0.57 - 8.5 cases/1000 person years of antiretroviral therapy. The onset of lactic acidosis is usually insidious and patients complain of nausea, vomiting, abdominal pain, fatigue and weight loss. When lactate levels are high enough, a catastropic clinical situation develops, resulting in multiorgan failure. The mortality rate of patients with lactic acidosis related to nucleoside therapy is very high, 33 - 60%. Although all nucleoside analogues have been implicated in lactic acidosis, most cases are associated with stavudine. At present, there are no controlled trials to evaluate the treatment of nucleoside-induced lactic acidosis. Therapy is based on supportive measures and discontinuation of all antiretroviral drugs. ...
Lactic acidosis in the ICU is most often seen in relation to systemic hypoperfusion or hypoxia. This case illustrates severe metabolic acidosis with markedly elevated lactate levels following cardiac arrest on another, and far more uncommon, basis.

However, there is a lot of doubt about the clearance of lactate. One paper studied 10 patients that were in AKI and lactic acidosis and checked stable lactate levels pre and post CRRT. They concluded that the mean lactate concentration actually increased despite renal replacement therapy. He medial total plasma lactate clearance was 1379ml/min(range 754-1881) and the median filter lactate clearance was 24ml/min suggesting that the filter lactate clearance accounted for only ,3% of total lactate clearance. Hence CRRT doesnt compete with lactate overproduction. If the cause is Type B lactic acidosis and a drug induced nature or ethanol induced, removing the offending agents via dialysis might be beneficial. There are case reports of metformin induced lactic acidosis being treated with dialysis, all met with some form of skepticism ...

In 1925, Clausen identified the accumulation of lactic acid in blood as a cause of acid-base disorder. Several decades later, Huckabees seminal work firmly established that lactic acidosis frequently accompanies severe illnesses and that tissue hypoperfusion underlies the pathogenesis. In their classic 1976 monograph, Cohen and Woods classified the causes of lactic acidosis according to the presence or absence of adequate tissue oxygenation.The normal blood lactate concentration in unstressed patients is 0.5-1 mmol/L. Patients with critical illness can be considered to have normal lactate concentrations of less than 2 mmol/L. Hyperlactatemia is defined as a mild-to-moderate persistent increase in blood lactate concentration (2-5 mmol/L) without metabolic acidosis, whereas lactic acidosis is characterized by persistently increased blood lactate levels (usually >5 mmol/L) in association with metabolic acidosis (pH < 7.35).1,2 Lactic acidosis is associated with major metabolic dysregulation, tissue
Metformin improves glycemic control in type 2 diabetes without causing weight gain or hypoglycemia and is the only oral hypoglycemic drug that has reduced cardiovascular morbidity and mortality in a randomized trial (1). However, metformin might increase the risk for lactic acidosis. For this reason, many prescribing guidelines suggest that metformin be contraindicated in patients at higher-than-average risk for lactic acidosis. Salpeter and colleagues hoped to compare the incidence of lactic acidosis in metformin users with those taking other medications or placebo, but this proved impossible because not a single case of lactic acidosis was found in any of these studies. Although many of the included studies did not specifically exclude persons with renal, hepatic, cardiac, or pulmonary disease, it is possible that not enough persons with these comorbid conditions were enrolled in the studies to allow accurate risk estimates. In Saskatchewan, where comprehensive, linkable databases of ...
Title: Lactic Acidosis, Hypotension, and Sensorineural Hearing Loss Following Intentional Metformin Overdose. VOLUME: 6 ISSUE: 5. Author(s):Dale K. Miller, Amanda J.

Abstract: Metformin and glyburide are antihyperglycemic agents that are widely used in the United States. There have been several cases of overdose of these medications reported in the world literature. Glyburide overdose is associated with hypoglycemia that can be severe, while metformin overdoses have been associated with lactic acidosis. In many cases of metformin overdose, lactic acidosis has led to profound hypotension and respiratory failure.

SUMMARY. The first reported case of lactic acidosis secondary to severe anemia with complete and immediate reversal of the acidosis after transfusion with packed red blood cells is described in a patient with pernicious anemia. Experimental evidence that severe anemia can cause widespread tissue hypoxia is cited. The pathophysiology, causal classification, and diagnosis of lactic acidosis are reviewed. ...
There have been post-marketing cases of metformin-associated lactic acidosis, including fatal cases. These cases had a subtle onset and were accompanied by nonspecific symptoms such as malaise, myalgias, abdominal pain, respiratory distress, or increased somnolence; however, hypothermia, hypotension and resistant bradyarrhythmias have occurred with severe acidosis. Metformin-associated lactic acidosis was characterized by elevated blood lactate … Read More Xigduo. ...

N2 - Pyruvate dehydrogenase complex (PDHC) activity was measured in cultured fibroblasts from 12 patients with Friedreichs ataxia (FA), and in 1 patient with lactic acidosis and ataxia. The activities obtained after extraction of PDHC by different methods were compared. Triton-X-100 extraction yielded enzyme activities 5 to 10 times greater than those obtained with the older methods. With this sensitive technique, PDHC activity was markedly deficient in fibroblasts from the patient with lactic acidosis and ataxia but it was normal in the fibroblasts from FA patients. Mg++activation of the PDHC in FA fibroblasts was normal.. AB - Pyruvate dehydrogenase complex (PDHC) activity ...
Lactic acidosis occurs when the body produces too much lactic acid and cannot metabolize it quickly enough. The condition can be a medical emergency. The onset of lactic acidosis might be rapid and occur within minutes or hours, or gradual, happening over a period of days. The best way to treat lactic acidosis is to f
This study provides a unique opportunity to prospectively assess the relationship of lactic acidemia with liver dysfunction and to determine whether lactic acidemia and liver dysfunction are likely to be secondary to NRTI-induced mitochondrial toxicity. If lactic acidemia and hepatic fatty infiltration (steatosis) in this study population are secondary to NRTI-induced mitochondrial toxicity, withdrawal of NRTI medications can be expected to result in partial improvement or resolution of these findings. Furthermore, this study will examine the possible additive ill effects of NRTI-induced mitochondrial toxicity on liver function in individuals coinfected with hepatitis C.. This study is designed both as a stand-alone ACTG protocol providing an NRTI-sparing regimen and as a study coenrollable simultaneously with A5116.. Patients enrolling in A5133 as a stand-alone study: Patients on NRTI-containing regimens with elevated lactates and ALTs are enrolled into a single open-label NRTI-sparing ...

N2 - The mitochondrial pyruvate oxidation route is a tightly regulated process, which is essential for aerobic cellular energy production. Disruption of this pathway may lead to severe neurometabolic disorders with onset in early childhood. A frequent finding in these patients is acute and chronic lactic acidemia, which is caused by increased conversion of pyruvate via the enzyme lactate dehydrogenase. Under stable clinical conditions, this process may remain well compensated and does not require specific therapy. However, especially in situations with altered energy demands, such as febrile infections or longer periods of fasting, children ...
In four patients with mitochondrial myopathy, encephalopathy, lactic acidosis, and strokelike episodes (MELAS) in which mutated mitochondrial deoxyribonucleic acid was seen, hypertrophic cardiomyopathy and angiopathy was demonstrated by echocardiogra
A 30-yr-old man with acquired immunodeficiency syndrome treated with zidovudine developed biopsy-proven mitochondrial myopathy. Chronic lactic acidosis (lactate, 10 +/- 1 mmol/L) persisted for more than 5 wk. Liver function tests were normal, but the concentration of lactose rose to 16.1 mmol/L when 500 mmol of ethanol was infused. The concentration of lactose rose by only 1.5 mmol/L with maximally tolerated exercise. If this mitochondrial lesion compromised flux through the electron transport system, increased turnover of ATP with exercise should have exacerbated the degree of lactic acidosis because of increased need to regenerate ATP via glycolysis. Two possible explanations will be discussed: first, there was both a rapid rate of production of lactic acid in affected muscles in conjunction and an equally rapid rate of removal by uninvolved organs. Second, there was a low net rate of production of lactic acid in involved muscles despite the exercise. ...
Lactic acidosis is a form of metabolic acidosis with a high anion gap, reduced rate of arterial blood pH under 7.35 mmol/l, and lactic acid concentration over 7 mmol/l. In the literature we can find some descriptions of the cases of lactic acidosis in patients with severe systemic diseases...
As mentioned previously, lactic acidosis can arrise from several etiologies. It is generally due to clinically evident tissue hypoperfusion (Type A) or the absence of clinically evident tissue perfusion (Type B). Type B1 is from underlying disease states (e.g. asthma, liver failure, systemic inflammation, malignancy, thiamine deficiency, hypophosphatemia, d-Lactic acidosis, hypoglycemia). Type B2 is from toxins or medication (e.g. alcohols, cyanide, antiretrovirals, metformin, beta-2 receptor agonists, salicylates, nitroprusside, carbon monoxide, propofol), and B3 is inborn errors of metabolism (e.g. MELAS and others).. Lactate production. In the cytoplasm of virtually all cells, glucose metabolism starts with glycolysis, an anaerobic pathway. The product of glycolysis is pyruvate, which then diffuses into the mitochondria and becomes part of the Krebs cycle through an aerobic pathway. In the absence of adequate oxygen, pyruvate is not metabolized in the Krebs cycle, but rather converted in the ...
Several abstracts were available on the incidence and natural history of hyperlactatemia and lactic acidosis. Graeme Moyle [Abs 98] presented cross sectional data on lactic acid measurements obtained from patients in his clinic between Aug 1999 to June 2001. Of a total of 4361 lactate measurements performed on 2069 patients, 8.7% had lactates > 2.5 mmol/l while 0.8% (9 individuals) had severe hyperlactatemia defined as > 5 mmol/l. The median lactate in 1239 subjects receiving antiretroviral medications for at least 4 months was 1.4 mmol/l whereas in the population of 253 HIV-positive untreated individuals the median lactate as 1.1 mmol/l. The results of repeat measurements in individuals with high lactates indicated that a single elevated lactate had limited predictive value suggesting that many elevations of lactates were transient. In contrast, in those with normal lactate levels, there was a high predictive value for subsequent normal levels. Events were more common with ddI based regimens, ...

This eMedTV resource looks at a life-threatening potential side effect of metformin: lactic acidosis. This page describes some of the symptoms of lactic acidosis and lists some of the factors that can increase your risk of developing this condition.
A 6 year old Portuguese boy with dilated cardiomyopathy had abundant ragged red fibres in muscle (20% of total) and severe lactic acidosis. Molecular genetic analysis showed the A to G transition in the mitochondrial transfer RNALeu(UUR) gene at nt 3243 (MELAS mutation), which accounted for 88% and 68% of the total mtDNA in his muscle and blood, respectively. Molecular studies in blood from 16 maternal relatives identified lower percentages of the mutation only in the oligo-symptomatic mother and brother. This case reinforces the notion that cardiomyopathy can be the presenting and predominant clinical expression of the A3243G mutation.. ...

Metformin, a biguanide derived from guanidine, was introduced in the 1950s as a treatment for diabetes, and remains widely used today with 40 million prescriptions filled worldwide in 2008 (1). Lactic acidosis is the primary toxicity of concern, with an estimated incidence of 0.03 per 1000 patients/year (2). Metformin-associated lactic acidosis may happen with therapeutic doses or after an acute overdose. Currently the data is mixed as to which situation leads to a more severe pattern of illness. Common initial symptoms are non-specific and include nausea, vomiting, diarrhea, abdominal pain, malaise, and decreased oral intake. In severe cases, altered mental status, tachypnea, hypothermia or cardiovascular collapse may occur. ...

We present the case of a 70-year-old Caucasian man who took a deliberate metformin overdose of unknown quantity. He had a profound lactic acidosis at presentation with a pH of 6.93 and a lactate level of more than 20mmol/L. These figures would normally correspond with a mortality of more than 80%; however, with appropriate management this patients condition improved ...

TY - JOUR. T1 - Natural History of Lactic Acidosis after Grand-Mal Seizures. T2 - A Model for the Study of an Anion-Gap Acidosis Not Associated with Hyperkalemia. AU - Orringer, Carl E.. AU - Eustace, John C.. AU - Wunsch, Christian D.. AU - Gardner, Laurence B.. PY - 1977/10/13. Y1 - 1977/10/13. N2 - To define the time course of the metabolic acidosis that follows a single grand-mal seizure, we obtained serial blood samples from eight consecutive patients. Immediately after a seizure, the mean (± S.E.M.) venous lactate concentration was 12.7±1.0 meq per liter, the mean carbon dioxide content 17.1±1.1 nmol per liter, and the mean arterial pH 7.14±0.06. Sixty minutes later their values were 6.6±0.7 meq per liter (P,0.005), 23.6±1.1 mmol per liter (p,0.005) and 7.38±0.04 (P,0.005) respectively. The spontaneous resolution of the acidosis was due, in large part, to the metabolism of lactate and to the concomitant removal of hydrogen ion. There was no change in the serum potassium ...

We report three families presenting with hypertrophic cardiomyopathy, lactic acidosis, and multiple defects of mitochondrial respiratory chain (MRC) activities. By direct sequencing of the candidate gene MTO1, encoding the mitochondrial-tRNA modifier 1, or whole exome sequencing analysis, we identified novel missense mutations. All MTO1 mutations were predicted to be deleterious on MTO1 function. Their pathogenic role was experimentally validated in a recombinant yeast model, by assessing oxidative growth, respiratory activity, mitochondrial protein synthesis, and complex IV activity. In one case, we also demonstrated that expression of wt MTO1 could rescue the respiratory defect in mutant fibroblasts. The severity of the yeast respiratory phenotypes partly correlated with the different clinical presentations observed in MTO1 mutant patients, although the clinical outcome was highly variable in patients with the same mutation and seemed also to depend on timely start of pharmacological ...

The exact mechanism and role of metformin in the setting of MALA is a controversial subject. The mechanism for the reduction of hepatic gluconeogenesis is due to inhibition of mitochondrial respiratory chain complex I causing a decline in cellular ATP production. Gluconeogenesis, an energetically costly process, is reduced as the result of an impaired energy state. It is this mitochondrial impairment that leads to a buildup of lactic acid, a substrate of stalled gluconeogenesis. It is a very commonly used drug, but MALA is a rather rare clinical entity. The role of metformin in the development of lactic acidosis had not been completely elucidated and is further complicated in the literature by many reported cases of MALA without elevated metformin concentrations.. Metformin does not undergo hepatic metabolism and is primarily excreted through the renal system unchanged. Predisposing conditions leading to renal failure are typically associated with MALA. MALA should likely be categorized into ...
Objective: To determine whether an elevated osmolal gap is specific for toxic alcohol ingestion.. Design: Cross-sectional.. Setting: Emergency room and medical and surgical inpatient wards at a university-affiliated hospital.. Patients: Twenty-three patients with lactic acidosis, 19 with alcoholic ketoacidosis, and 10 randomly selected controls.. Measurements and Main Results: Calculated and measured serum osmolality was determined in all study participants. The osmolal gap was increased in patients with lactic acidosis (17.4 ± 5.4 mmol/kg) and alcoholic ketoacidosis (26.9 ±7.6 mmol/kg) when compared with controls (- 1.7 ±1.7 mmol/kg, P , 0.05 for both comparisons). When ethanol was included in the calculation, the osmolal gap remained elevated in the lactic acidosis (10.3 ±2.0 mmol/kg) and alcoholic ketoacidosis (11.1 ±3.2 mmol/kg) groups (P , 0.05 for both comparisons).. Conclusions: The osmolal gap is often used as a screen for toxic alcohol ingestion. When calculating the osmolal gap, ...
Telbivudine can cause severe side effects, including myositis, neuritis, rhabdomyolysis, and lactic acidosis. However, reported cases of telbivudine leading to multiple organ failure are rare. Here, we report a case of telbivudine-induced severe polymyositis, lactic acidosis, and multiple organ failure. A 30-year-old Chinese man with hepatitis B virus infection received antiviral treatment with 600 mg of telbivudine daily for more than 11 months. He developed progressive weakness and myalgia, and subsequently experienced palpitations, chest tightness, lethargy, hypotension, and hypoxemia. Blood tests showed markedly elevated levels of alanine aminotransferase (955 U/L), aspartate aminotransferase (1375 U/L), blood urea nitrogen (14.9 mmol/L), creatine kinase (peak at 8050 U/L), and blood lactate (|20.0 mmol/L). His symptoms improved after continuous renal replacement therapy and short-term methylprednisolone treatment. Hyperbaric oxygen therapy, physical therapy, and rehabilitation for more than 2
A 14-month-old female infant presented with recurrent episodes of acute gastroenteritis accompanied by severe metabolic acidosis and hypoglycemia. Physical examination showed hepatomegaly. Laboratory evaluation revealed elevated hepatic enzymes, prolonged prothrombin time, hyperuricemia, and extremely elevated lactate and alanine levels. Glucagon injection during hypoglycemia resulted in a further decrease of blood glucose. She was treated with glucose-containing intravenous fluids, with rapid improvement and normalization of her blood pH and glucose levels. Hormonal assessment during two episodes of hypoglycemia indicated growth hormone (GH) deficiency. However, as isolated GH deficiency could not explain all other concomitant features, such as severe lactic acidosis, hepatomegaly, impaired liver function, and hyperuricemia, the possibility of a combined defect was suggested. Further lymphocytic enzymatic investigation revealed fructose-1,6-diphosphatase deficiency and molecular genetic ...
Mutations have been described in structural subunits of complex I7 and complex II.8 Complex III and IV defects are mostly due to mutations in genes needed for the assembly of their subunits. Several mutations in SURF1, SCO1, SCO2, and COX10 are responsible for complex IV disrupted activity,9 while mutations in the BCS1L gene cause complex III failure in patients.10,11 Interestingly, Holme described in 1992 the association of methylglutaconic aciduria and ATP synthase deficiency.12 The child presented with severe lactic acidosis, hypertrophic cardiomyopathy, and severe mitochondrial ATP synthase deficiency. Methylglutaconic aciduria seems to be a marker of inner mitochondrial membrane dysfunction and can also be seen in other OXPHOS defects. Complex V deficiency is more difficult to detect using spectrophotometric methods but easier with BN-PAGE followed by catalytic staining.. F0F1-ATP synthase is comprised of at least fourteen nuclear-encoded subunits and two mitochondrial DNA encoded subunits. ...

The reported incidence of lactic acidosis in patients receiving metformin hydrochloride is very low (approximately 0.03 cases/1000 patient-years, with approximately 0.015 fatal cases/1000 patient-years). In more than 20,000 patient-years exposure to metformin in clinical trials, there were no reports of lactic acidosis. Reported cases have occurred primarily in diabetic patients with significant renal insufficiency, including both intrinsic renal disease and renal hypoperfusion, often in the setting of multiple concomitant medical/surgical problems and multiple concomitant medications. Patients with congestive heart failure requiring pharmacologic management, in particular those with unstable or acute congestive heart failure who are at risk of hypoperfusion and hypoxemia, are at increased risk of lactic acidosis. The risk of lactic acidosis increases with the degree of renal dysfunction and the patients age. The risk of lactic acidosis may, therefore, be significantly decreased by regular ...
We used a comprehensive metabolomics approach to study the altered urinary metabolome of two mitochondrial myopathy, encephalopathy lactic acidosis and stroke like episodes (MELAS) cohorts carrying the m.3243A,G mutation. The first cohort were used in an exploratory phase, identifying 36 metabolites that were significantly perturbed by the disease. During the second phase, the 36 selected metabolites were able to separate a validation cohort of MELAS patients completely from their respective control group, suggesting usefulness of these 36 markers as a diagnostic set. Many of the 36 perturbed metabolites could be linked to an altered redox state, fatty acid catabolism and one-carbon metabolism. However, our evidence indicates that, of all the metabolic perturbations caused by MELAS, stalled fatty acid oxidation prevailed as being particularly disturbed. The strength of our study was the utilization of five different analytical platforms to generate the robust metabolomics data reported here. We ...
Because of its slower metabolism, only D-lactate accumulates and remains distributed in the human body as a low molecular weight organic acid until it is excreted unchanged in the urine. The clinical presentation of D-lactic acidosis seems to be the direct or indirect effect of the accumulation of D-lactic acid, and an intestinal origin for the disorder can be postulated. Above all, a prerequisite for this disorder is a short bowel abnormality. In patients with short bowel syndrome, carbohydrates that normally undergo sterile digestion in the small bowel reach the colon in undigested or partially digested form and are fermented to produce organic acids. This results in a progressive decrease in intraluminal pH, which alters the intestinal microenvironment favouring the overgrowth of acid resistant bacteria such as Lactobacillus acidophilus, Lactobacillus fermenti, and streptococcus. These are the main bacteria that produce D-lactate in both animals and humans.14,15 Secondly, stool flora show a ...
How the food you eat will affect the diabetes medication you take will depend on what enzyme is used by your liver to break down those medications. This is an overview of how several known diabetic drugs are processed in the liver and how they are affected by the foods you eat.. Metformin. Also known as Glucophage, metformin is one medication that does not get processed by the liver. This means the use of Metformin cannot be affected by the food you eat.. However, consumption of alcohol does affect metformin metabolism. Excessive alcohol in your system will lead to metformin breaking down too much lactate which can cause one of the metformin side effects known as lactic acidosis. Lactic Acidosis a serious condition that is characterised by an increased amount of lactate in the body and can cause multiple negative symptoms such as trouble breathing, weakness, diarrhea, vomiting, abdominal pain, muscle pain, and tiredness. In severe cases, lactic acidosis can be lethal. To avoid any negative ...
A word of caution while using Metformin to attenuate symptoms of COVID-19 is that Metformin has been found to adversely affect vitamin B12 (cobalamin) absorption in the small intestine by up to 30%. This in turn, reduces serum vitamin B12 level by 5%-10%. Vitamin B12 has been found to be extremely vital for maintaining optimal immune response. Thus, a cautious approach is mandatory while taking Metformin as lowered vitamin B12 level can weaken the immune response against SARS-CoV-2, which can cause more harm than good. Hence, individuals on Metformin are advised to take supplemental dose of the active form of vitamin B12 methyl cobalamin in order to negate this specific side effect.. Another rare yet potential side effect is the accumulation of lactic acid, also known as lactic acidosis as it can increase the risk of fatality in COVID-19 patients. The comorbidities which predispose an individual towards lactic acidosis due to Metformin usage are acute heart failure, acute pulmonary ...
Fialuridine, or 1-(2-deoxy-2-fluoro-1-D-arabinofuranosyl)-5-iodouracil (FIAU), is a nucleoside analogue that was investigated as a potential therapy for hepatitis B virus infection. In a 1993 clinical study at the NIH, unexpected toxicity led to the death of 5 out of 15 patients from liver failure associated with lactic acidosis; two further participants required liver transplantation. This toxicity was unusual in that it was not predicted by animal studies. It is suspected that the drugs toxicity was due to its damaging mitochondria. Tujios S, Fontana RJ.

These days the most exciting thing about watching Bobby Lashley fight is the spectacular way that he gasses out (and he always gasses out). Many MMA fighters have stamina problems, but Lashleys are something special to witness. His takedowns become hilariously sloppy, his eyes bulge like a strangled bullfrogs, and he starts to spit out his mouthpiece like an angry toddler. Youll see all of this and more in Lashleys fight against John Ott, which went down at Titan Fighting Championships 17 last night in Kansas City, Kansas. Even Frank Trigg cant resist calling Lashley a can in so many words during the broadcast. After the jump: the second part of Lashley vs. Ott and Phil Baroni vs. Nick Nolte (no, not that Nick Nolte).

Sikhulile Moyo, Hermann Bussmann, Phibeon Mangwendeza, Priti Dusara, Tendani Gaolathe, Madisa Mine, Rosemary Musonda, Erik van Widenfelt, Vladimir Novitsky, Joseph Makhema, Richard Marlink, Max Essex, C. William Wester. Publish Year : 2011. Background: Nucleoside reverse-transcriptase inhibitors (NRTIs) are a major component of combination antiretroviral therapy (cART) worldwide but they have been associated with mitochondrial toxicities, with one of the most significant being lactic acidosis. In southern Africa, being female and overweight (BMI > 25) as well as receiving d4T and/or ddI-based cART are risk factors for the development of this potentially life-threatening complication. It is challenging in many resource-limited settings to obtain reliable serum lactate measurements while screening for the presence of lactic acidosis. Point-of-care devices, however, are now available that provide simple, accurate measurements of serum lactate levels at relatively low cost. The objective of this ...

Mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) is a syndrome which is characterized as mitochondrial myopathy, encephalopathy, lactic acidosis and recurrent stroke-like episodes. Recurrent attacks of prolonged migrainous headache, different types of epileptic seizures and repeated cerebral lesions are the main clinical features of the disease. Cerebral lesions can cause different seizure types in this syndrome according to affected brain areas. Herein, we are reporting a case of MELAS who experienced recurrent neurologic deficits, confusional states and epileptic seizures with ictal epileptic nystagmus. Ictal electroencephalogram (EEG) recordings and magnetic resonance imaging (MRI) lesions also supported to the ictal focus of epileptic nystagmus. With this case, we would like to take attention to this rare ictal event. ...

Metformin reduces glucose levels in blood by decreasing the hepatic glucose production and intestinal glucose absorption, and by improving cell sensitivity to insulin by increasing peripheral uptake of glucose and utilization. These effects are mediated by the initial activation of AMP-activated protein kinase which is a liver enzyme that plays a significant role in insulin signalization, energy balance, and the metabolism of glucose and lipids. Activation of AMP- protein kinase is needed for inhibitory effect of metformin on liver cell production. Increased peripheral utilization of glucose is caused by improved insulin binding to its receptors. Metformin administration also increases AMP- protein kinase in skeletal muscle cells. AMP- protein kinase is known to cause deployment of GLUT-4 to the cell plasma membrane, which results in insulin-independent glucose uptake. The rare side effect called lactic acidosis can be caused by decreased liver uptake of lactate, which is one of the substrates ...

Metformin belongs to the Biguanide class of medications used to treat Type 2 Diabetes. Metformin works by decreasing the amount of glucose produced by the liver, improving insulin sensitivity, and by increasing cellular uptake of glucose.. In patients who develop acute or chronic renal failure, the clearance of metformin is decreased resulting in an increased risk of lactic acidosis, which may have a mortality rate up to 50%. Patients who receive IV contrast fluid are at risk for contrast-induced nephropathy and if they are concurrently on metformin, they may experience potentially fatal lactic acidosis. To avoid this issue, most patients scheduled to receive IV contrast have their metformin medication stopped at the time of contrast administration for at least 48 hours after the procedure.. NOTE: In some patients who have preserved renal function and are receiving small amounts of contrast (, 100 mL), stopping the metformin may not be necessary because the risk of contrast-induced nephropathy ...
Results Although metformin is renally cleared, drug levels generally remain within the therapeutic range and lactate concentrations are not substantially increased when used in patients with mild to moderate chronic kidney disease (estimated glomerular filtration rates, 30-60 mL/min per 1.73 m2). The overall incidence of lactic acidosis in metformin users varies across studies from approximately 3 per 100 000 person-years to 10 per 100 000 person-years and is generally indistinguishable from the background rate in the overall population with diabetes. Data suggesting an increased risk of lactic acidosis in metformin-treated patients with chronic kidney disease are limited, and no randomized controlled trials have been conducted to test the safety of metformin in patients with significantly impaired kidney function. Population-based studies demonstrate that metformin may be prescribed counter to prevailing guidelines suggesting a renal risk in up to 1 in 4 patients with type 2 diabetes ...

Guidelines Clearance of many of the oral hypoglycaemic drugs or discourage the use of metformin in patients with CKD their metabolic products (like that of insulin) is reduced because of its alleged potential to cause lactic acidosis.14 in diabetic patients with renal insufficiency. As a result However, some studies challenge this by showing that of such effects, patients will be exposed to higher levels metformin has less risk of causing lactic acidosis than- of respective drugs or their metabolites potentiating previously thought. Metformin has been shown to have side-effects. This has been found to be serious in patients no effect on intracellular lactate production.50-52 Even in with CKD stages 3 to 5 (eGFR ,60 ml/min). patients with renal failure, the use of metformin was not associated with significant rise in lactate levels.53-54 Diabetic patients on metformin developed significant These drugs are insulin secretagogues and increase the lactic ...
TY - JOUR. T1 - Metformin in chronic kidney disease. T2 - Time for a rethink. AU - Heaf, James. PY - 2014/1/1. Y1 - 2014/1/1. N2 - Metformin has traditionally been regarded as contraindicated in chronic kidney disease (CKD), though guidelines in recent years have been relaxed to permit therapy if the glomerular filtration rate (GFR) is , 30 mL/min. The main problem is the perceived risk of lactic acidosis (LA). Epidemiological evidence suggests that this fear is disproportionate. Lactic acidosis is a rare complication to type 2 diabetes mellitus (T2DM), with an incidence of 6/100,000 patient-years. The risk is not increased in metformin-treated patients. Metformin possesses a number of clinical effects independent of glucose reduction, including weight loss, which are beneficial to patients. The risk of death and cardiovascular disease is reduced by about a third in non-CKD patients. Since metformin intoxication undoubtedly causes LA, and metformin is renally excreted, inappropriate dosage of ...
Ensure proper control of diabetes and insulin requirements. Check blood gas analysis and blood lactate level because of the potential association with chronic lactic acidosis. Mental retardation may cause the patient to be uncooperative at induction of anesthesia and the benefit of a premedication must be weighed against the severity of the clinical condition. It is essential to ensure proper perioperative control of diabetes mellitus. Chronic lactic acidosis may be present and should be treated accordingly before any elective surgical procedures. ...

Mitochondrial defects have long been suspected to play an important role in the development of cancer. Fifty years ago, Warburg pioneered the research on the involvement of mitochondrial respiratory defects in cancer, and proposed a mechanism to explain how these defects evolve during carcinogenesis. Warburg hypothesized that a key event in carcinogenesis involved the development of an injury to the mitochondrial respiratory machinery, resulting in a compensatory increase in glycolysis, leading to lactic acidosis (29). Lactic acidosis is also a typical biochemical hallmark of mitochondrial diseases and it is widely used in the diagnosis of mitochondrial encephalomyopathies (26, 30) .. Although it has been shown that a majority of cancer cell lines harbor mutant mtDNA, it has not yet been determined whether mtDNA mutations precede and lead to carcinogenesis. In light of Warburgs theory, it would be especially interesting to better understand the role of mutant mtDNA associated with dysfunction ...
Regardless of concerns that people on keto diet plans eat too much protein, this does not appear to be the case for most people. Due to the fact that it is very filling, most people find it tough to overeat protein.55.. Although amino acids from protein foods can be converted to glucose, under experimental conditions, only a small percentage in fact are.56 This may be related to specific aspects, such as degree of insulin resistance.57 Nevertheless, even individuals with type 2 diabetes typically do well with the appropriate levels of protein Diet plan Medical professional recommends, if their diet plans are also low carbohydrate.58.. At the same time, inadequate protein consumption over extended time periods is a major issue. It can result in loss of muscle and bone, especially as you age.. Prevent snacking when not starving.

TY - JOUR. T1 - Guanidinoethane sulfate. T2 - Brain pH alkaline shifter. AU - Nakada, T.. AU - Kwee, Ingrid. PY - 1993. Y1 - 1993. N2 - A new category of agents, brain pH alkaline shifters, is described. Using the prototype agent, guanidinoethane sulfate (GES), the actual alkaline shift in pH was demonstrated in adult mice brain by 31-phosphorus (31P) nuclear magnetic resonance (NMR) in vivo spectroscopy. This alkaline shift was also shown to effectively reduce the extent of brain intracellular lactic acidosis brought about by anoxic insult. These findings support the notion that a pH alkaline shift may protect the brain against the deleterious effects of lactic acidosis. Since higher pH has been shown to significantly reduce beta-amyloid deposition, alkaline shifters may also have therapeutic potential in Alzheimers disease..
