From the Research

Pneumonia and Hypernatremia

  • Pneumonia can cause various electrolyte disturbances, including hyponatremia and hypernatremia 1, 2, 3, 4, 5.
  • Hypernatremia is less common than hyponatremia in patients with pneumonia, with a prevalence of 1.9% to 5.3% in different studies 3, 4.
  • The relationship between pneumonia and hypernatremia is not as well-studied as the relationship between pneumonia and hyponatremia.
  • However, one study found that hypernatremia was associated with a worse outcome in patients with community-acquired pneumonia, including higher 30-day and 1-year mortality rates 3.

Factors Associated with Hypernatremia in Pneumonia

  • Female gender, higher leukocyte counts, and higher urea levels were associated with hypernatremia in patients with community-acquired pneumonia 3.
  • Hypernatremia was also associated with a higher risk of mortality and longer hospital stays in some studies 3, 4.

Comparison with Hyponatremia

  • Hyponatremia is more common than hypernatremia in patients with pneumonia, with a prevalence of 25.3% to 31% in different studies 1, 2, 3, 4, 5.
  • Hyponatremia is associated with a higher risk of mortality, longer hospital stays, and more severe illness in patients with pneumonia 1, 2, 3, 4, 5.
  • The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a common cause of hyponatremia in patients with pneumonia 1, 2.
