Hyponatremia Clinical Trial
Official title:
Changes in Serum Creatinine Levels Can Help Distinguish Hypovolemic From Euvolemic Hyponatremia
Retrospective study that analyzes the changes in serum creatinine as a tool to correctly classify the volemic status volemic status (euvolemia vs hypovolemia) of the patients with hyponatremia.
This study evaluates the usefulness of the changes in serum creatinine in differentiating between euvolemia and hypovolemia in hyponatremic patients. Changes in serum creatinine were retrospectively analyzed . The latter was calculated subtracting the serum creatinine value of eunatremia from that of hyponatremia, and was categorized as an increase when it was "positive", or "decrease/no change" when it was negative or equal to zero. The percentual change in serum creatinine was also calculated. Two groups of patients were selected for the current study. First group was conformed by patients with hypovolemic hyponatremia, and second group by patients with euvolemic hyponatremia. Data from eunatremia as well as the hyponatremic episode were collected. Both groups were matched in Receiver operating characteristic curve analyzes where both arithmetical and percentual changes in serum creatinine were assessed and cut-off points were selected for an additional Odd Ratio analysis. ;
