The biologically active chloride concentration is the concentration of free chloride in the plasma water. Hyperchloremia is defined as an increase in the chloride concentration in the plasma water.

The tight coupling between sodium and chloride transport in the TALH is underscored by one of the varieties of Bartter syndrome in which defects in basolateral chloride channels disrupt sodium chloride reabsorption and mimics the renal defect observed with abnormal NKCC2 proteins. Intercellular junctions in the later proximal tubule become more permeable to chloride facilitating paracellular transport. Chloride concentration and hyperchloremia The serum chloride level is generally measured as a concentration of chloride in a volume of serum.

This article reviews the handling of chloride by the kidney and clinical situations in which hyperchloremia can occur. Hyperchloremia also occurs when hydrochloric acid HCl is added to the blood. Changes in electrolyte and acid-base balance.

Thus, the segments of distal convoluted tubule display direct coupling of sodium and chloride transport via the NCC and indirect coupling of transport via passive movement down an electrochemical gradient.

Meaning of “hipocloremia” in the Portuguese dictionary

The organic acid formic or oxalic acid is recycled into cells. In many segments of the gastrointestinal tract and associated exocrine organs such as the pancreas, bicarbonate is secreted into the gut in exchange for chloride so that loss of bicarbonate, especially in secretory forms of diarrhea, can be associated with bicarbonate losses which are associated with chloride retention.


NaCl restriction upregulates renal Slc26a4 through subcellular redistribution: The net result would be the transport of 1 sodium and 1 chloride into the cell. Thick ascending limb of the loop of Henle. Regulation of renal bicarbonate reabsorption by extracellular volume. Resuscitation-induced intestinal edema and related dysfunction: By contrast, bicarbonate and other non-chloride anions are rapidly absorbed with sodium and removed from the filtrate 7 Fig.

Acidose metabólica de intervalo aniônico elevado

The collecting duct plays an important role in determining the chloride content of the final urine. Causaz and a relative excess of chloride in the body have been linked to the development of reduced renal blood flow, 12 increased interstitial edema including in the kidney and gastrointestinal system, 3 excess morbidity and mortality in critically ill patients, 45 and reduced survival and recovery in patients with acute kidney injury.

Electrolytes and blood gases.

Further regulation of NCC and NKCC may occur through WNK kinases, which may serve as chloride sensors 12 and can regulate these transporters by modifying trafficking or their phosphorylation state.

Severe hypernatremia from sea water ingestion during near-drowning in a hurricane. As long as renal function is preserved, non-chloride acid anions do not accumulate in the systemic circulation maintaining a relatively hipocloremiia anion gap. When the kidneys repair the metabolic acidosis, ammonium chloride hpocloremia excreted in the urine while bicarbonate that is made in the proximal tubule as a byproduct of the glutamine metabolism is returned to the blood.

Desequilibrio Hidro – Electrolítico by Jesus benavides on Prezi

Mice deficient in this protein develop hypertension when exposed to a high sodium chloride load. Hyperchloremia can result from a variety of conditions including water depletion, excessive chloride exposure and metabolic acidosis. In the early portion of the proximal tubule, chloride absorption also occurs via apical chloride-anion formate, oxalate, base exchangers and it exits the cell via basolateral membrane transporters 8 Fig.


Chloride reabsorption in this portion of the nephron helps to conserve chloride in response to low chloride intake and can contribute to the hypertensive effects of a high sodium chloride diet. The organ that is responsible for the maintenance of chloride balance in the body is the kidney. Renal handling of phosphate and sulfate. The pathogenic cause of hyperchloremia will provide guidance on how the disturbance should be treated: Renal handling of chloride The level of the chloride in the plasma is regulated by the kidney.

Iodide and negative anion gap. Nevertheless, certain clinical situations may favor the use of normal saline including in patients with hypochloremic metabolic alkalosis or those with cerebral edema.

The level of the chloride in the plasma is regulated by the kidney. If NDCBE transport is coupled with pendrin-mediated chloride-bicarbonate exchange, the two transporters working together could result in net sodium chloride reabsorption from the lumen, as the bicarbonate recycles into and out of the cell while sodium and chloride enter the cell 17 Fig. List of key points The kidney plays a key role in maintaining chloride balance in the body.

The kidney freely filters chloride across the basement membranes of the glomeruli. The sudden large input of seawater average salinity is 3.
