Blockade of ATP-sensitive potassium channels in cerebral arterioles inhibits vasoconstriction from hypocapnic alkalosis in cats. (1/239)

BACKGROUND AND PURPOSE: Recent studies have shown that the cerebral arteriolar dilation from hypercapnic acidosis is blocked by agents which inhibit KATP channels. These findings suggested that this response is due to opening of KATP channels. Because the repose to CO2 is a continuum, with hypercapnic acidosis causing vasodilation and hypocapnic alkalosis causing vasoconstriction, it would be expected that the response to hypocapnic alkalosis would be due to closing of KATP channels. There are no studies of the effect of inhibition of KATP channels on the response to hypocapnic alkalosis. METHODS: We investigated the effect of 3 agents that in earlier studies were found to inhibit KATP channels--NG-nitro-L-arginine, hydroxylysine, and glyburide--on the cerebral arteriolar constriction caused by graded hypocapnia induced by hyperventilation in anesthetized cats equipped with cranial windows. RESULTS: Hypocapnic alkalosis caused dose-dependent vasoconstriction that was inhibited completely by each of the 3 inhibitors of KATP channels. The blockade induced by these agents was eliminated in the presence of topical L-lysine (5 micromol/L). CONCLUSIONS: The findings show that agents which inhibit ATP-sensitive potassium channels in cerebral arterioles inhibit the vasoconstriction from hypocapnic alkalosis. These and earlier results showing that inhibition of KATP channels inhibited dilation from hypercapnic acidosis demonstrate that the response to CO2 in cerebral arterioles is mediated by the opening and closing of KATP channels.  (+info)

Intracellular pH regulation by HCO3-/Cl- exchange is activated during early mouse zygote development. (2/239)

We report here that at least one major pHi-regulatory mechanism, the HCO3-/Cl- exchanger, is quiescent in unfertilized mouse eggs but becomes fully activated during early development following fertilization. Zygotes (8-12 h postfertilization) exhibited a marked intracellular alkalinization upon external Cl- removal, which is indicative of active HCO3-/Cl- exchangers, in contrast to the very small response observed in eggs. In addition, efflux of Cl- from eggs upon external Cl- removal was much slower than that from zygotes, indicating additional pathways for Cl- to cross the plasma membrane in zygotes. Furthermore, while zygotes quickly recovered from an induced alkalosis, eggs exhibited only a slow, incomplete recovery. Following in vitro fertilization (IVF), increased HCO3-/Cl- exchanger activity was first detectable about 4 h postfertilization and reached the maximal level after about 8 h. The upregulation of HCO3-/Cl- exchanger activity after fertilization appeared to occur by activation of existing, inactive exchangers rather than by synthesis or transport of new exchangers, as the increase in activity following IVF was unaffected by inhibition of protein synthesis or by disruption of the Golgi apparatus or the cytoskeleton. This activation may depend on the Ca2+ transients which follow fertilization, as suppression of these transients, using the Ca2+ chelator BAPTA, reduced subsequent upregulation of HCO3-/Cl- exchanger activity by about 50%. Activation of pHi-regulatory systems may be a widespread feature of the earliest period of embryonic development, not restricted to species such as marine invertebrates as previously believed.  (+info)

H+-K+-ATPases: regulation and role in pathophysiological states. (3/239)

Molecular cloning experiments have identified the existence of two H+-K+-ATPases (HKAs), colonic and gastric. Recent functional and molecular studies indicate the presence of both transporters in the kidney, which are presumed to mediate the exchange of intracellular H+ for extracellular K+. On the basis of these studies, a picture is evolving that indicates differential regulation of HKAs at the molecular level in acid-base and electrolyte disorders. Of the two transporters, gastric HKA is expressed constitutively along the length of the collecting duct and is responsible for H+ secretion and K+ reabsorption under normal conditions and may be stimulated with acid-base perturbations and/or K+ depletion. This regulation may be species specific. To date there are no data to indicate that the colonic HKA (HKAc) plays a role in H+ secretion or K+ reabsorption under normal conditions. However, HKAc shows adaptive regulation in pathophysiological conditions such as K+ depletion, NaCl deficiency, and proximal renal tubular acidosis, suggesting an important role for this exchanger in potassium, HCO-3, and sodium (or chloride) reabsorption in disease states. The purpose of this review is to summarize recent functional and molecular studies on the regulation of HKAs in physiological and pathophysiological states. Possible signals responsible for regulation of HKAs in these conditions will be discussed. Furthermore, the role of these transporters in acid-base and electrolyte homeostasis will be evaluated in the context of genetically altered animals deficient in HKAc.  (+info)

pH regulation of K(+) efflux from myocytes in isolated rat hearts: (87)Rb, (7)Li, and (31)P NMR studies. (4/239)

This study investigates the effects of intracellular (pH(i)) and extracellular pH (pH(e)) on the efflux of Rb(+) and Li(+) in isolated rat hearts. (87)Rb and (7)Li NMR were used to measure Rb(+) and Li(+) content, respectively, of hearts, and (31)P NMR was used to monitor pH(i), pH(e), and phosphate levels. After 30-min equilibration with Rb(+) or Li(+), effluxes were initiated by switching perfusion to a Rb(+)- or Li(+)-free, high-K(+) (20.7 mM) Krebs-Henseleit buffer with 15 microM bumetanide. Monensin (2 microM) increased pH(i) from 7.10 +/- 0.05 to 7.32 +/- 0.07 and resulted in activation of Rb(+) efflux; the first-order rate constant (k x 10(3), in min(-1)) increased from 42 +/- 2 to 116 +/- 16. Glibenclamide (4 microM) did not inhibit monensin-activated Rb(+) efflux (k = 110 +/- 17), whereas quinine (0.2 mM) slightly inhibited it by 19 +/- 9%. Infusion of 15 mM NH(4)Cl during Rb(+) washout increased k for Rb(+) efflux by 93% (81 +/- 8), which was glibenclamide and quinine insensitive, and caused a transient increase in pH(i) to 7.25 +/- 0.08. Intracellular Li(+) inhibited NH(4)Cl-stimulated Rb(+) efflux by 55%. Monensin and NH(4)Cl stimulated Li(+) efflux by 40%, increasing k from 29 +/- 3 to 43 +/- 7 and 41 +/- 3, respectively. The stimulation was not sensitive to 10 microM dimethylamiloride. Intracellular acidosis that resulted from the washout of NH(4)Cl (pH 6.86 +/- 0.2) slightly inhibited Rb(+) efflux (k = 36 +/- 5), whereas NH(4)Cl itself in the absence of pH(i) changes did not markedly affect Rb(+) efflux. A moderate increase in pH(i) (7.17 +/- 0.06) produced by washout of 15 mM 2, 2-dimethylpropionate (DMP)-Tris from hearts preequilibrated with DMP did not markedly affect Rb(+) efflux. Neither global alkalosis (pH(i) 7.4, pH(e) 7.55) nor acidosis (pH(i) approximately pH(e) 6.8) produced by 3 mM Tris base or 5 mM MES, respectively, affected Rb(+) efflux. We suggest that intracellular alkalosis stimulates Rb(+) (K(+)) and Li(+) effluxes by activating a nonselective sarcolemmal K(+) (Li(+))/cation exchanger or a K(+) (Li(+))-anion symporter.  (+info)

Renal responses of trout to chronic respiratory and metabolic acidoses and metabolic alkalosis. (5/239)

Exposure to hyperoxia (500-600 torr) or low pH (4.5) for 72 h or NaHCO(3) infusion for 48 h were used to create chronic respiratory (RA) or metabolic acidosis (MA) or metabolic alkalosis in freshwater rainbow trout. During alkalosis, urine pH increased, and [titratable acidity (TA) - HCO(-)(3)] and net H(+) excretion became negative (net base excretion) with unchanged NH(+)(4) efflux. During RA, urine pH did not change, but net H(+) excretion increased as a result of a modest rise in NH(+)(4) and substantial elevation in [TA - HCO(-)(3)] efflux accompanied by a large increase in inorganic phosphate excretion. However, during MA, urine pH fell, and net H(+) excretion was 3.3-fold greater than during RA, reflecting a similar increase in [TA - HCO(-)(3)] and a smaller elevation in phosphate but a sevenfold greater increase in NH(+)(4) efflux. In urine samples of the same pH, [TA - HCO(-)(3)] was greater during RA (reflecting phosphate secretion), and [NH(+)(4)] was greater during MA (reflecting renal ammoniagenesis). Renal activities of potential ammoniagenic enzymes (phosphate-dependent glutaminase, glutamate dehydrogenase, alpha-ketoglutarate dehydrogenase, alanine aminotransferase, phosphoenolpyruvate carboxykinase) and plasma levels of cortisol, phosphate, ammonia, and most amino acids (including glutamine and alanine) increased during MA but not during RA, when only alanine aminotransferase increased. The differential responses to RA vs. MA parallel those in mammals; in fish they may be keyed to activation of phosphate secretion by RA and cortisol mobilization by MA.  (+info)

The pathophysiological and molecular basis of Bartter's and Gitelman's syndromes. (6/239)

Molecular defects affecting the transport of sodium, potassium and chloride in the nephron through the ROMK K+ channel, Na+/K+/2Cl- cotransporter, the Na+/Cl- cotransporter and chloride channel have been identified in patients with Bartter's and Gitelman's syndromes. Defects of the angiotensin II type I receptor and CFTR have also being described. These defects are simple (i.e., most are single amino acid substitutions) but affect key elements in tubular transport. The simplicity of the genetic defects may explain why the inheritance of these conditions remains unclear in most kindreds (i.e., not just recessive or dominant) and emphasises the crucial importance of the conformational structure of these channels. Application of this molecular information will allow the early genetic identification of patients with these syndromes and enable us to differentiate between the various disorders at a functional level. It may also identify a subgroup in which the heterozygous form may make patients potentially exquisitely sensitive to diuretics.  (+info)

Defective processing and expression of thiazide-sensitive Na-Cl cotransporter as a cause of Gitelman's syndrome. (7/239)

Gitelman's syndrome is an autosomal recessive disorder of salt wasting and hypokalemia caused by mutations in the thiazide-sensitive Na-Cl cotransporter. To investigate the pathogenesis of Gitelman's syndrome, eight disease mutations were introduced into the mouse thiazide-sensitive Na-Cl cotransporter and studied by functional expression in Xenopus oocytes. Sodium uptake into oocytes that expressed the wild-type clone was more than sevenfold greater than uptake into control oocytes. Uptake into oocytes that expressed the mutated transporters was not different from control. Hydrochlorothiazide reduced Na uptake by oocytes expressing the wild-type gene to control values but had no effect on oocytes expressing the mutant clones. Western blots of oocytes injected with the wild-type clone showed bands representing glycosylated (125 kDa) and unglycosylated (110 kDa) forms of the transport protein. Immunoblot of oocytes expressing the mutated clones showed only the unglycosylated protein, indicating that protein processing was disrupted. Immunocytochemistry with an antibody against the transport protein showed intense membrane staining of oocytes expressing the wild-type protein. Membrane staining was completely absent from oocytes expressing mNCC(R948X); instead, diffuse cytoplasmic staining was evident. In summary, the results show that several mutations that cause Gitelman's syndrome are nonfunctional because the mutant thiazide-sensitive Na-Cl cotransporter is not processed normally, probably activating the "quality control" mechanism of the endoplasmic reticulum.  (+info)

Expression of rat kidney anion exchanger 1 in type A intercalated cells in metabolic acidosis and alkalosis. (8/239)

By enzyme-linked in situ hybridization (ISH), direct evidence is provided that acid-secreting intercalated cells (type A IC) of both the cortical and medullary collecting ducts of the rat kidney selectively express the mRNA of the kidney splice variant of anion exchanger 1 (kAE1) and no detectable levels of the erythrocyte AE1 (eAE1) mRNA. Using single-cell quantification by microphotometry of ISH enzyme reaction, medullary type A IC were found to contain twofold higher kAE1 mRNA levels compared with cortical type A IC. These differences correspond to the higher intensity of immunostaining in medullary versus cortical type A IC. Chronic changes of acid-base status induced by addition of NH(4)Cl (acidosis) or NaHCO3 (alkalosis) to the drinking water resulted in up to 35% changes of kAE1 mRNA levels in both cortical and medullary type A IC. These experiments provide direct evidence at the cellular level of kAE1 expression in type A IC and show moderate capacity of type A IC to respond to changes of acid-base status by modulation of kAE1 mRNA levels.  (+info)

Volume depletion and potassium depletion may coexist in some disorders (eg vomiting). Severe potassium depletion alone can cause a metabolic alkalosis but this is typically only of mild to moderate degree. The mechanism seems to be related to an intracellular shift of H+ (intracellular acidosis) in exchange for K+. The alkalosis is generated predominantly due to non-renal mechanisms. Renal mechanisms are frequently involved in causing the potassium depletion (eg in syndromes of mineralocorticoid excess).. Volume depletion has long been implicated in maintenance of an alkalosis. The idea is that hypovolaemia is associated with increased fluid and sodium reabsorption in the proximal tubule and bicarbonate is reabsorbed in preference to chloride; the alkalosis thus being maintained. The role of volume depletion has probably been over-emphasised: the co-existing chloride depletion is the most important factor responsible for persistence of the alkalosis. Correction of the volume deficit without ...
Our study indicates that synaptic transmission and spike encoding related to the active function of cortical GABAergic neurons are more vulnerable to alkalosis than acidosis (Figures 1, 2, 3, 4), which explains well-known facts that patients suffered from alkalosis show severer brain dysfunction and that alkalosis-induced neuropsychological deficits are difficultly corrected, compared with those suffered from acidosis [11, 12]. Vulnerable changes in our analyses include the amplitudes and frequencies of synaptic analogue signals and the capability of neuronal encodings in the digital spikes. The final molecular targets for alkalosis versus acidosis actions will be the voltage-gated sodium channels, glutamate receptors, GABA receptors and transmitter release machineries in cortical GABAergic neurons.. We first showed the differential vulnerability of GABAergic neurons to alkalosis and acidosis by analyzing the influence of alkalosis or acidosis on their responsiveness to excitatory synaptic ...
Metabolic Alkaloses can be compensated by the actions of the lungs which serve to realign the bicarbonate buffer Henderson-Hasselbalch Equation over a period of hours. As described in Respiratory Acid-Base Control, the lungs respond to alkalosis by decreasing alveolar ventilation, essentially a physiological hypoventilation, which in turn increases the partial pressure of arterial carbon dioxide (PaCO2). The increased PaCO2 realigns the Henderson-Hasselbalch Equation for the bicarbonate buffer and thus largely corrects the ECF pH. Consequently, a respiratory-compensated metabolic alkalosis is characterized by increased levels of ECF bicarbonate (caused by the primary metabolic disturbance) as well as increased levels of PaCO2 (caused by the respiratory compensation). More colloquially, the lungs compensate for the metabolic alkalosis by slowing "Breathing Off" of acid in the form of CO2, thus helping reduce ECF pH. However, it is important to point out that respiratory compensation cannot ...

To the editor: We read with interest the recent article by Swartz and colleagues that described hemodialysis with a high-chloride, low-acetate dialysate as a successful treatment for metabolic alkalosis in the postoperative patient with renal failure (1).. We recently treated a 37-year-old man who had suffered a gunshot wound to the abdomen that required extensive abdominal surgery. The patient subsequently developed acute renal failure and a severe metabolic alkalosis that was secondary to nasogastric suctioning. Hemodialysis with a high-chloride, low-acetate dialysate was very effective in correcting the metabolic alkalosis.. Before dialysis the blood pH was 7.57 and plasma bicarbonate 42 ...
Liddle syndrome (LS) is a familial disease characterized by early onset hypertension (HT). Although regarded as rare, its incidence may be greater than expected because the classical findings of hypokalemic metabolic alkalosis with suppressed renin and aldosterone levels are not consistently present. Herein, we present the case of an adolescent boy and maternal relatives who were followed up with misdiagnosis of essential HT for a long duration. Clinical diagnosis of LS was confirmed on genetic analysis. Despite carrying the same mutation, the index patient and the family members manifested heterogeneous phenotypes of the disease including age at presentation, degree of HT, presence of hypokalemia and renal/cardiac complications ...
We measured cerebral intracellular pH using in vivo phosphorus-31 nuclear magnetic resonance spectroscopy during 1 week after forebrain ischemia or sham operation in eight and seven rats, respectively. Mean maximum pH was significantly higher (p less than 0.003) in the ischemic group than in the sham-operated group (7.34 +/- 0.03 and 7.19 +/- 0.02, respectively). The difference between mean maximum pH and baseline pH (7.08 +/- 0.01 in each group) was significantly greater (p less than 0.02) in the ischemic group than in the sham-operated group. In the ischemic group, alkalosis occurred primarily after 48-72 hours of recirculation. We speculate that brain tissue alkalosis occurring chronically after ischemia is associated with delayed ischemic neuronal death. ...
Metabolic alkalosis is common-half of all acid-base disorders as described in one study [1] . This observation should not be surprising since vomiting, the use of chloruretic diuretics, and nasogastric suction are common among hospitalized patients. The mortality associated with severe metabolic alkalosis is substantial; a mortality rate of 45% in patients with an arterial blood pH of 7.55 and 80% when the pH was greater than 7.65 has been reported [2] . Although this relationship is not necessarily causal, severe alkalosis should be viewed with concern, and correction by the appropriate intervention should be undertaken with dispatch when the arterial blood pH exceeds 7.55..

Introduction. Gitelmans Syndrome (GS) is the most common primary renal tubular disorder, affecting approximately 1/40,000 Caucasians. GS is inherited as an autosomal recessive disease mainly linked to mutations in the SLC12A3 gene (solute carrier family 12 sodium/chloride transporters, member 3), that encodes a thiazide-sensitive sodium-chloride co-transporter (NCC) protein that locates at the luminal membrane of the distal convoluted tubule in the kidney.1 GS is characterized by hypokalemic metabolic alkalosis with hypomagnesemia and hypocalciuria.2,3 The loss of function of the NCC channel leads to decreased sodium re-absorption and subsequently secondary volume depletion. The hypovolemia stimulates sodium re-absorption at the expense of increased potassium and hydrogen secretion, which results in hypokalemia and metabolic alkalosis.4 Hypocalciuria and hypomagnesaemia are also characteristic of GS, the latter being a likely consequence of the elevation of the excretion of magnesium in ...
Used in intravenous administration as an acidifier in severe metabolic alkalosis. It is also used orally to acidify urine and as a diuretic and as an expectorant because of its irritant properties on the respiratory mucosa. Oral and general use of this drug has fallen into disuse because of its poor efficacy and irritant properties on the gastric mucosa. Since the last update we have not found published data on its excretion in breast milk. After being absorbed in the intestine, it is rapidly metabolized in the liver as urea. The small amounts of ammonium in cough mixtures will hardly affect breastfeeding or the infant. It is advisable to avoid it due to its inefficacy or to use it moderately during breastfeeding. It has multiple industrial uses: fertilizers, explosives, metallurgy (soldered, galvanized and welded), batteries, detergents, etc. Exposure limits in these TLV industries (such as TWA) should be maintained: 10 mg / m³ and TLV (as STEL): 20 mg / m³. Ammonium chloride has no R

Cerebral blood flow was measured with the 133Xenon clearance method during short-lasting (20 minutes) and more prolonged (90 minutes) infusions of Na2CO3 solutions in anesthetized cats under controlled ventilation. The infusion protocol was regulated so as to produce a given increase in the plasma [HCO3-] in the first 15 minutes, followed by a constant high plasma level for the rest of the infusion period. A high Paco3 level was induced before and at the end of the infusion, when prolonged infusions were made. The results indicate that, in acute experiments (20 minutes), an increase in plasma [HCO3-] of 14 mEq/l does not influence CBF. During more prolonged infusions (90 minutes), an increase of 12 mEq/l produces a reduction of CBF and an increase in the CSF [HCO3-]. These changes are more pronounced when the increase in plasma [HCO3-] is more marked (18 mEq/l).. ...

Using the lab values given, determine if the patient is in alkalosis or acidosis, if it is metabolic or respiratory and if it is being compensated for. Give specific reasons for your answers. pH = 7.5; PCO2 = 24 mm Hg; HCO3- = 18.
The degree of acidity or alkalinity is an important property of our blood. The acidity level increases with the increase in the level of acidic compounds in our body, or when the level of basic (also known as alkaline) compounds present in our body falls. The alkalinity level in our body increases when the reverse takes place, i.e., when the level of acidic compounds falls or when the basic compounds in the body increase. The acidity or alkalinity of any solution is indicated on the pH scale. Even a minor shift from the normal range can destroy our organs. Generally, the normal acidic level (pH) of our blood is close to 7.4. When the pH level falls below 7.35, then we say that acidosis has occurred. On the other hand, when the pH goes above 7.45, then we say that alkalosis has occurred. We have a severe case of the former, when the pH value of blood goes below 7.0; while a severe case of the latter can occur when the pH value goes above 7.5. Let us now see what are the various causes and ...

Chronic obstructive pulmonary disease (COPD) can lead to intensive care unit (ICU) admission with some patients requiring the need for invasive mechanical ventilation. Acetazolamide has been used as a respiratory stimulant in patients with COPD and metabolic alkalosis. Faisy and colleagues conducted the DIABLO study to determine whether acetazolamide reduces mechanical ventilation duration in critically ill patients with COPD and metabolic alkalosis. The DIABLO study was a randomized, double-blind, multicenter, parallel-group trial conducted from October 2011 to July 2014 in 15 ICUs in France. Patients were randomized to receive either 500 mg or 1000 mg (if loop diuretics were co-prescribed) of acetazolamide twice daily or placebo (10mL of saline). The primary end point of the study was duration of invasive mechanical ventilation via endotracheal intubation or tracheotomy with secondary end points including alterations in arterial blood gas and respiratory parameters, weaning duration, adverse ...

Males (N = 10) performed nine minutes of isotonic wrist flexion in a control condition and induced alkalosis condition (0.3 g/kg of Na HCO3 1.5 hours before testing). The onset of intracellular acidosis and intracellular threshold were determined for the exercise. Acidosis was similar in both conditions at the start and up to seven minutes into the exercise. During the final 1.8 minutes the induced alkalosis condition maintained less acidity and a better level of phosphocreatine. Implication.

Dr. Hussain Azhar, Assistant Professor Medical Unit ll, Civil Hospital Karachi, was invited for a lecture on ABG and Fluid Management. Dr. Hussain started with the basics of Arterial Blood Gases (ABGs), and emphasized on checking acidosis and alkalosis first. He described acidosis and alkalosis with reference to the pH values. He explained metabolic acidosis, a situation in which pH is decreased due to fall in bicarbonate ions concentration.. For the basic understandings of fluid management, he first explained different fluid compartments of the body and the percentage of total fluids. Then he enlightened about different options to balance the fluids of the body out of which the common fluids are normal saline, dextrose water and ringers lactate. Among these fluids, the normal saline is given most commonly to resuscitate the patient in emergency room.. ...
To determine the contribution of changes in extracellular osmolarity to ischemic injury, isolated guinea pig hearts were perfused with hyposmotic (220 mosM) or hyperosmotic (380 mosM) buffer. 31P NMR spectroscopy was used to follow changes in intracellular pH (pHi) and energetics. Hyposmotic buffer decreased myocardial developed pressure by 30 +/- 2% and pHi by 0.02 +/- 0.01 unit, whereas hyperosmotic buffer increased myocardial developed pressure by 34 +/- 1% and pHi by 0.14 +/- 0.01 unit. All hearts recovered to control values on restoration of isosmotic (300 mosM) buffer. The hyperosmolar-induced intracellular alkalosis and developed pressure increase were not prevented by inhibition of Na+/H+ exchange with use of 1 microM HOE-642 but were abolished with use of bicarbonate-free buffers. After 20 min of total global ischemia, hearts perfused with hyposmotic buffer showed significantly greater recoveries of developed pressure, phosphocreatine, and ATP than control hearts, but hearts perfused with

In 1 we will find the explanation of clinical results obtained by intravenous CH1 injections, even if the blood pH did not change.. In 2 we find the reason for clinical results obtained by increasing neutral salts intake. Ambard gives the following reaction:. NaCl+2CO3 NaHCO3+HCl. Whereas this reaction gives birth to infinitesimal quantities of HCl, if it takes place in the presence of albumin, the acid will impregnate the albumin and a new quantity of NaCl can be decomposed and liberates a new fraction of chlorine.. Here then we have first of all a new characteristic of proteins. It is therefore possible to perceive, that though the proteins are charged with acid, the medium many manifest a neutral reaction. Chabanier and Lobo-Onell have shown that even an increase of acid, producing an acidemia (of the medium), will allow the albumins to discharge themselves of HCl if the neutral salt content is diminished. It is possible, therefore, to have an acidemia (of the medium) and an alkalosis (of the ...

Introduction: Distal renal tubular acidosis is a rare genetic disease, characterised by deficit in renal tubular transport. Clinical features are metabolic acidosis with hypercloraemia and hypokalemia, and inability in urine acidification. Hypercalciuria may also be present, often treated with the use of a diuretic therapy with thiazides. Case Presentation: We present a severe disease onset in a neonate with consanguineous parents, both autosomal-recessive for an ATP6VOA4 gene mutation, and a nevertheless severe episode of metabolic alkalosis, occurred in the same patient after few months, during the diuretic therapy. Conclusion: Biochemical results lead us to hypothesize a susceptibility to the treatment that need further investigations. ...

Acetazolamide-mediated decrease in strong ion difference accounts for the correction of metabolic alkalosis in critically ill patients : Metabolic alkalosis is a commonly encountered acid-base derangement in the intensive care unit. Treatment with the carbonic anhydrase inhibitor acetazolamide is indicated in selected cases. According to the quantitative approach described by Stewart, correction of serum pH due to carbonic anhydrase inhibition in the proximal tubule cannot be explained by excretion of bicarbonate. Using the

Respiratory alkaloses can be compensated by the actions of the kidneys which serve to realign the bicarbonate buffer Henderson-Hasselbalch Equation over a period of several days. As described in Renal Response to Acid-Base Imbalance, the kidneys respond to alkalosis by excreting bicarbonate, thus reducing the ECF bicarbonate concentration. The decreased bicarbonate concentration realigns the Henderson-Hasselbalch Equation for the bicarbonate buffer and thus largely corrects the ECF pH. Consequently, a renally-compensated respiratory alkalosis is characterized by decreased levels of PaCO2 (caused by the primary ventilatory disturbance) as well as decreased levels of ECF bicarbonate (caused by the renal compensation). However, it is important to point out that renal compensation cannot completely correct the ECF pH and thus the ECF will still remain slightly alkalotic even after compensation ...

agonists appears to promote movement of K out of cells. Plasma K can also be affected significantly by plasma pH. Acute metabolic acidosis promotes the movement of K out of cells into the ECF. Acute metabolic alkalosis promotes the transfer of K in the opposite direction. However, changes in plasma HCO3 concentration may be more important than changes in pH in this regard. Thus, acidosis caused by accumulation of mineral acids (non-anion gap, hyperchloremic acidosis) is more likely to show an elevation of plasma K due to transcellular shifts. In contrast, metabolic acidosis due to accumulation of organic acids (increased anion gap acidosis) does not cause hyperkalemia. Thus, the hyperkalemia that frequently accompanies diabetic ketoacidosis results from insulin deficiency and ECF hypertonicity rather than from acidosis per se. Acute respiratory acidosis and alkalosis appear to have less of an effect on plasma K concentration than do metabolic disturbances. Nonetheless, the plasma K concentration ...
The original substitution and/or dialysates used for continuous hemofiltration and/or dialysis were either based on peritoneal dialysis fluids, or peritoneal dialysates themselves. Although these fluids have been refined over the years, by changing the anionic base from acetate or racemic d+ l-lactate, to bicarbonate or l-lactate, the fluids remain designed for low volume hourly exchanges. Even at relatively low volume exchanges, the composition of these fluids can affect systemic acidbase balance. Those fluids which contain a higher concentration of lactate with a corresponding lower chloride, predispose to a hypochloremic alkalosis, whereas those with a lower concentration of lactate with a corresponding higher chloride potentially lead to a hyperchloremic acidosis ...

Although the acid-base status can be variable -- depending on the degree of overdose, and the point in the timeline after ingestion at which the patient is seen -- the most common chemical results seen are a metabolic acidosis + respiratory alkalosis . This is seen as an acidemia with a lower than expected C02 compensation. The respiratory alkalosis occurs because of salicylates direct stimulation on the respiratory centers. One should note that the respiratory alkalosis can be masked by other medications that may have been ingested at the same time, such as benzodiazepines, and tricyclic antidepressants. The metabolic acidosis comes from acetylsalicylic acid, salicylic acid, and the production of lactic acid, free fatty acids, and amino acids ...
Abstract. In cirrhotic patients, in addition to hepatocytes and Kuppfer cells dysfunction circulatory anatomic shunt and ventilation/perfusion (VA/ Q) ratio abnormalities can induce decrease in partial pressure of oxygen in arterial blood (PaO2), in oxygen saturation of hemoglobin (SaO2) as well as various acid-base disturbances. We studied 49 cases of liver cirrhosis (LC) with ascites compared to 50 normal controls. Causes were: posthepatic 37 (75.51%), alcoholic 7 (14.24%), cardiac 2 (4.08%), and cryptogenic 3 (6.12%). Complications were: upper gastrointestinal bleeding 24 (48.97), hepatic encephalopathy 20 (40.81%), gastritis 28 (57.14%), hepatoma 5 (10.2%), renal hepatic syndrome 2 (4.01%), HbsAg (+) 24 (48.97%), and hepatic pleural effusions 7 (14.28%). Average PaO2 and SaO2 were 75.2 mmHg and 94.5 mmHg, respectively, compared to 94.2 mmHg and 97.1 mmHg of the control group, respectively (p value in both PaO2 and SaO2 was p,0.01). Respiratory alkalosis, metabolic alkalosis, metabolic ...
oxygen in the inspired gas in the lungs. This change leads in turn to less pressure driving oxygen diffusion from the alveoli and throughout the oxygen cascade. A normal initial "struggle response" to such an ascent includes increased ventilation, which is the cornerstone of acclimation. Hyperventilation may cause respiratory alkalosis and dehydration. Alkalosis may depress the ventilatory drive during sleep, with consequent periodic breathing and hypoxemia. During early acclimation, renal suppression of carbonic anhydrase and excretion of dilute alkaline urine combat alkalosis and tend to bring the pH of the blood to normal. Other physiologic changes during normal acclimation include increased sympathetic tone; increased ...
Summary A transient period of asphyxia in the newborn is an obligatory part of normal parturition. A more prolonged disturbance in cerebral blood supply is a major cause of neonatal seizures. Current therapies of birth asphyxia seizures are ineffective and the underlying mechanisms are unknown. Our recent landmark work on a rat model of birth asphyxia showed that asphyxia is followed by brain alkalosis, which triggers seizures. The brain-confined alkalosis is generated by activation of Na/H exchange in the blood-brain barrier (BBB). Both alkalosis and the consequent seizures can be suppressed by graded restoration of the high CO2 level after asphyxia and with blockers of Na/H exchange. Our pilot data indicate that arginine vasopressin (AVP) triggers the post-asphyxia seizures by activating the BBB-located luminal V1a receptor-coupled Na/H exchanger. Akin to human infants, a very high level of plasma copeptin (a part of pro-AVP) is seen following asphyxia but, notably, the copeptin levels remain ...
Fresenius manufactures GranuFlo and NaturaLyte used in dialysis. These drugs cause alkalosis, a condition associated with an increase in cardiovascular fatalities. The FDA received complaints describing alkali dosing errors that occurred during hemodialysis using dialysate concentrates containing acetic acid and acetate. When metabolized, these potential sources of alkali can contribute to elevated bicarbonate levels in patients undergoing hemodialysis. This can contribute to metabolic alkalosis, which is a significant risk factor associated with : Low blood pressure Cardiopulmonary arrest Cardiac arrhythmia Sudden heart attack Stroke Hemodialysis cardiopulmonary arrest A study which was conducted between January and December of 2010 found that patients with pre-dialysis bicarbonate levels greater than 28mEq/L were 4.7 times more likely to suffer a cardiac arrest. The study also discovered that patients with pre-dialysis potassium lower than 4 mEq/L had a 6.3 times higher risk of cardiac arrest. ...

First, look at the pH; in this case it is alkalotic. You must now distinguish if this is respiratory, mixed, or metabolic. So pay attention to the pCO2 and the HCO3 and note that the HCO3 is normal but the pCO2 is low. The characteristic of respiratory alkalosis is increase in pH with decrease in pCO2. In the acute setting, note that HCO3 typically decreases by 2 mEq/L for every 10 mm Hg drop in pCO2. In chronic respiratory alkalosis, HCO3 typically increases by 4 mEq/L of HCO3 for every 10 mm Hg drop in pCO2. ...
Date ___________. Dear Emergency Worker. My patient _________________ has a rare kidney disorder called (Bartters or Gitelmans) Syndrome. This is a renal wasting disorder that frequently causes the patient to have hypokalemia, hypomagnesemia, and metabolic alkalosis. Dehydration is a common problem. There is not one specific treatment to help these patients treatment is to replace the lost minerals, electrolytes and fluid and try to decrease the renal wasting by giving potassium sparing diuretics, ace inhibitors, prostaglandin inhibitors and Cox 2 inhibitors. Lab tests are good for an initial diagnosis of this disorder, but is not a reliable source for adequate future treatments. Many patients with this disorder will feel ok and have severe abnormalities in their labwork, whereas others are very symptomatic and have normal labs. Therefore the patient should be treated primarily based on symptoms and not labwork.. If my patient ____________________ presents to your Emergency Facility with ...
A recent report from the National Kidney Foundation 2011 Spring Clinical Meetings retrospectively evaluated 50 hemodialysis patients hospitalized in October 2010. Their outpatient dialysate prescription included a 35 mEq/L bicarbonate solution and an acid concentrate which contained 8 mEq/L of acetate (total bicarbonate of 43 mEq/L). At presentation, the patients mean serum bicarbonate level was 31.3 mEq/L and 54 percent had a serum bicarbonate ,30 mEq/L. (Pande S, Raja R, Bloom E, Chewaproug D, Dissanayake I.

4) Alkalosis (both metabolic and respiratory) causes increased activity of pH-dependent enzymes in glycolytic pathway that promotes lactate production. pH has to exceed 7.6 for this effect to show. However, in the presence of liver dysfunction, the lactate clearance will be less than normal and therefore, this effect may result in hyperlactatemia at lower pH. (Alkalosis induced hyperlactatemia is an undesirable consequence of alkali therapy for lactic acidosis ...

Inappropriate prescription of NaturaLyte and GranuFlo products can lead to a high serum bicarbonate level in patients undergoing hemodialysis. These products can help kidney failure patients during the process of dialysis by converting into bicarbonate, which helps clean the bloodstream of a patient in a way that the kidneys would otherwise be able to do. However, the FDA investigation showed that doctors were administering the drug at too high a level for healthy human consumption. Dosage errors may contribute to metabolic alkalosis, which is a significant risk factor associated with low blood pressure, hypokalemia, hypoxemia, hypercapnia and cardiac arrhythmia, which, if not appropriately treated, may culminate in cardiopulmonary arrest.

Six studies met our inclusion criteria, which involved a total of 658 circuits. In these six studies patients with liver failure or a high risk of bleeding were excluded. The circuit life span in the RCA group was significantly longer than that in the control group, with a mean difference of 23.03 h (95% CI 0.45-45.61 h). RCA was able to reduce the risk of bleeding, with a risk ratio of 0.28 (95% CI 0.15-0.50). Metabolic stability (electrolyte and acid-base stabilities) in performing RCA was comparable to that in other anticoagulation modes, and metabolic derangements (hypernatremia, metabolic alkalosis, and hypocalcemia) could be easily controlled without significant clinical consequences. Two studies compared mortality rate between RCA and control groups, with one reported similar mortality rate and the other reported superiority of RCA over the control group (hazards ratio 0.7).. ...

Do you suffer from stress, fatigue or take prescription medication? If on top of this you have an unbalanced diet you probably need support to regulate your acid-base balance. For your body to function optimally as it should, the acid-base balance must be in equilibrium…unfortunately our modern lives makes this very difficult.So what does acid-base balance actually mean? Your body maintains a very tight range of blood pH in order to keep you alive, if your blood goes out of this range it can lead to metabolic acidosis or alkalosis which can be deadly. Since survival is always the main objective of your body, it will intelligently do whatever it takes to maintain this balance, even if it means compromising other aspects of your health. Consistent external and internal stressors such as metabolic waste (think of lactic acid that is released by your body during exercise), high stress hormones, inflammation, processed foods, environmental toxins, unfiltered water and medications all contribute to ...

Sclerochoroidal calcification is an uncommon benign condition characterised by yellow-white subretinal masses that typically lie along the superotemporal vascular arcades in elderly Caucasian patients.1 Histopathologically, the lesions represent deposition of calcium pyrophosphate in the sclera and/or choroid.2 It is hypothesised that their superotemporal location may be related to the insertion of the superior oblique muscle.. Most cases of sclerochoroidal calcification are idiopathic, however occasionally there may be an underlying systemic cause such as hypercalcemia, hyperparathyroidism or hypomagnesemia. For this reason, baseline blood tests should be checked. The condition has been associated with renal tubular hypokalemic metabolic alkalosis syndromes including Bartter and Gitelman syndromes.1 Imaging features have been described by Fung et. al.3 These include fundus hyperautofluorescence and a "rocky" configuration on enhanced-depth imaging optical coherence tomography (EDI-OCT). The ...
Gitelmans syndrome: Find the most comprehensive real-world symptom and treatment data on Gitelmans syndrome at PatientsLikeMe. 52 patients with Gitelmans syndrome experience fatigue, depressed mood, pain, anxious mood, and insomnia.
Gitelman syndrome is an autosomal recessive kidney disorder characterized by low blood levels of potassium and magnesium, decreased excretion of calcium in the urine, and elevated blood pH. The disorder is caused by genetic mutations resulting in improper function of the thiazide-sensitive sodium-chloride symporter (also known as NCC, NCCT, or TSC) located in the distal convoluted tubule of the kidney. This symporter is a channel responsible for the transport of multiple electrolytes such as sodium, chloride, calcium, magnesium, and potassium. Gitelman syndrome was formerly considered a subset of Bartter syndrome until the distinct genetic and molecular bases of these disorders were identified. Bartter syndrome is also an autosomal recessive hypokalemic metabolic alkalosis, but it derives from a mutation to the NKCC2 found in the thick ascending limb of the loop of Henle. Affected individuals may not have symptoms in some cases. Symptomatic individuals present with symptoms identical to those of ...
Before induction of anesthesia, electrocardiographic leads were attached and continuous ST segment analysis of lead II and V5(60 ms after the j-point; Sirecust 1281; Siemens, Erlangen, Germany) was initiated. A 20-gauge catheter was placed in the radial artery to measure mean arterial pressure and to collect blood samples. Anesthesia was induced with 2 [micro sign]g/kg sufentanil and 0.1 mg/kg pancuronium bromide. After tracheal intubation, patients were ventilated by a volume-controlled respirator (AV 1, Drager, Lubeck, Germany) with an inspiratory fraction of oxygen of 0.3. During the measurement period, anesthesia was maintained by a continuous infusion of sufentanil (3.5 [micro sign]g [middle dot] kg-1[middle dot] h-1). Body temperature was kept constant using warm covers. Subsequently, the following catheters were inserted: a flow-directed pulmonary artery catheter (Hands-off thermodilution catheter AH-0500; ARROW, Erding, Germany) via the left subclavian vein to measure mean pulmonary ...
Delta ratio is a formula that can be used to assess elevated anion gap metabolic acidosis and to evaluate whether a mixed acid base disorder (metabolic acidosis) is present. The anion gap (AG) is calculated first and if an anion gap is present, results in either a high anion gap metabolic acidosis (HAGMA) or a normal anion gap acidosis (NAGMA). A low anion gap is usually an oddity of measurement, rather than a clinical concern. The equation for calculating the Delta Ratio is: (AG - 12) ___________ (24 - [HCO3¯]) and reflects either an increase in the anion gap or a decrease in the bicarbonate concentration ([HCO3¯]). The ratio gives one of four results: 1. < 0.4 due to a pure NAGMA 2. 0.4 - 0.8 due to a mixed NAGMA + HAGMA 3. 0.8 - 2.0 due to a pure HAGMA 4. >2.0 due to a mixed HAGMA + metabolic alkalosis (or pre-existing compensated respiratory acidosis) Results 2 and 4 are the ones which have mixed acid-base disorders. Results 1. and 4. are oddities, mathematically speaking: Result 1: if ...
