Exploring Water-free Sodium Storage


Sponsor

Yale University

Enrollment

10 participants

Start Date

Oct 3, 2025

Study Type

INTERVENTIONAL

Conditions

Summary

The overarching goal of this proposal is to definitively establish if acute water free Na storage and release occurs, if the amount stored/released is of a quantity that is physiologically relevant, and if the location is intracellular vs. extracellular.


Eligibility

Min Age: 18 Years

Inclusion Criteria7

  • ESRD Patients actively undergoing PD with a reliably functioning PD catheter
  • Systolic blood pressure \> 130 mmHg
  • Serum sodium \>135 mmol/L
  • daily urine output \< 400ml
  • stable PD prescription for at least 2 months without requirement of 4.25% glucose PD solution
  • PD vintage of at least 6 months
  • Euvolemic as defined by the patient at their dry weight and free of any signs or symptoms of volume overload, per referring nephrologist

Exclusion Criteria8

  • Poorly controlled diabetes with hemoglobin A1C\>9%
  • or more episodes of peritonitis in the previous 6 months or active infection of the peritoneal dialysis catheter
  • Anemia with hemoglobin \<8g/dL
  • Inability to give written informed consent or follow study protocol.
  • Urinary incontinence
  • Body weight \< 60kg
  • gastrointestinal disease that causes diarrhea or expectation of sodium losses in stool.
  • use of amiodarone in the last 6 months (which will interfere with tissue iodine ascertainment).
