How does liver disease cause hyponatremia?

How does liver disease cause hyponatremia?

Patients with cirrhosis may develop hyponatremia due to either hypovolemia (example: loss of extracellular fluid due to diuretics) or hypervolemia (expanded extracellular fluid volume due to the inability of the kidneys to excrete solute-free water proportionate to the amount of free water ingested).

What causes Legionella hyponatremia?

While pneumonias caused by numerous pathogens share similar laboratory findings, hyponatremia (sodium < 130 mEq/L) secondary to the syndrome of inappropriate antidiuretic hormone (SIADH) is more common in Legionnaires disease (LD) than in pneumonias secondary to other pathogens; however, this is not specific for LD.

Can liver disease cause an electrolyte imbalance?

The common disorders of fluid, electrolyte and acid-base metabolism observed in patients with liver cirrhosis are hyponatremia, hypokalemia, respiratory alkalosis, and metabolic acidosis, in addition to an excess accumulation of body fluids with edema and ascites formation.

Can liver affect sodium levels?

Hyponatremia is also associated with numerous complications in liver disease patients, including severe ascites, hepatic encephalopathy, infectious complications, renal impairment, increased severity of liver disease in cirrhosis, and increased hospital stay and neurologic/infectious complications posttransplant.

Can Legionella cause elevated liver enzymes?

As demonstrated in Table 1, Legionella CAP patients had higher concentrations of CRP, lactate dehydrogenase (LDH) and creatinine kinase (CK), more frequently elevated liver enzymes, proteinuria and hemoglobinuria and lower concentrations of sodium, platelets and pH as compared to non-Legionella CAP patients.

How is Hypoosmolar hyponatremia treated?

In cases of chronic hyponatremia or mild symptoms water restriction is the main cornerstone of treatment. Diurectics and vaptans are the other drugs used. In some severe, symptomatic or acute cases 3% NaCl is needed.

How long does it take to correct hyponatremia?

In patients with severe symptomatic hyponatremia, the rate of sodium correction should be 6 to 12 mEq per L in the first 24 hours and 18 mEq per L or less in 48 hours. A bolus of 100 to 150 mL of hypertonic 3% saline can be given to correct severe hyponatremia.

Is hyponatremia a symptom of cirrhosis?

Hyponatremia in cirrhosis: pathophysiology and management Hyponatremia is frequently seen in patients with ascites secondary to advanced cirrhosis and portal hypertension. The development of ascites in patients with cirrhosis is multi-factorial.

How is hyponatremia treated in patients with liver disease?

The management of this patient includes free water restriction, holding diuretics, and consideration of albumin infusion (Fig. 1 ). Tolvaptan is not recommended in patients with liver disease. Furthermore, hyponatremia and renal dysfunction are associated with poor prognosis.

What is the prevalence of hyponatremia in the United States?

United States. The incidence of hyponatremia depends largely on the patient population and the criteria used to establish the diagnosis. Among hospitalized patients, 15-20% have a serum sodium level of < 135 mEq/L, while only 1-4% have a serum sodium level of less than 130 mEq/L. The prevalence of hyponatremia is lower in the ambulatory setting.

Is dilutional hyponatremia in cirrhosis associated with vasopressin receptors?

Keywords: Hyponatremia in cirrhosis, Dilutional hyponatremia, Hypervolemic hyponatremia, Vasopressin receptor antagonists, Vaptans Core tip:Hyponatremia is the most common electrolyte abnormality observed in hospitalized patients and is a common finding in patients with advanced cirrhosis.
