Hyponatremia in Community-Acquired Pneumonia

Abstract
Background/Aim: Community-acquired pneumonia (CAP) is a frequent cause for hospitalization and may result in a number of different renal and electrolyte complications. The purpose of this study was to describe the incidence of hyponatremia in CAP and to analyze risk factors for its occurrence. Methods: Records were reviewed for all 342 subjects who participated in the Community-Acquired Pneumonia Standardized Order Set study, a 2-year trial of supplemental treatment tools in hospital pneumonia treatment. Results: Hyponatremia (serum sodium concentration Conclusion: Hyponatremia is a common complication present at the time of admission for CAP. It is associated with more severe illness, increased mortality risk and extended hospital stays. Hyponatremia develops less frequently during the hospitalization and is unrelated to severity of illness on admission, but is an iatrogenic complication and thus initial treatment with isotonic saline may reduce the risk of this complication.
