Phosphate in Acute Pancreatitis (PPP)

24. August 2026 aktualisiert von: Duke University

Phosphate in Acute Pancreatitis (PPP)

The goal of this study is to learn if phosphate administration works to treat acute pancreatitis in adults presenting to the emergency department at Duke University Hospital. The main questions it aims to answer are:

Does having low phosphate levels increase the risk of acute pancreatitis and can giving phosphate through an IV make the illness less severe?
Is phosphate therapy practical to use, and what is the appropriate dose?
Is this study achievable, and how can the results help design a future randomized controlled trial to assess safety and effectiveness?

Participants will:

Receive standard of care or intravenous (IV) phosphate during their hospital stay
Have blood samples collected during admission to monitor phosphorus levels
Complete follow-up assessments after hospital admission to evaluate how severe the illness is and the effects of phosphate supplementation

Detaillierte Beschreibung

This prospective, two-phase pilot clinical trial will enroll 100 adult emergency department patients with acute pancreatitis (50 per phase) at Duke University Hospital.

Phase one will consist of an observational control group receiving usual care, with serum phosphorus collected throughout the emergency department visit and hospitalization to examine how phosphorus levels change over time and relate to disease severity and clinical outcomes.

Phase two will include a treatment group receiving continuous intravenous sodium phosphate or potassium phosphate infusions to maintain high-normal serum phosphorus levels (4.0-4.5 mg/dL) during the first 72 hours of hospitalization. Phosphate dosing requirements will be determined and compared across varying levels of disease severity to assess whether more severe illness is associated with greater supplementation needs.

Overall, the study will characterize phosphorus dynamics in acute pancreatitis, evaluate the feasibility and dosing of phosphate repletion, and generate preliminary data to inform the design of a future randomized controlled trial assessing the safety and efficacy of phosphate therapy.

Teilnehmergruppe / Arm	Intervention / Behandlung
Kein Eingriff: Standard of Care Observational Phase During the first year of enrollment, 50 control group participants will be enrolled in an observational phase and receive usual care only with fluid resuscitation at the discretion of the clinical team. Serum phosphorus levels will be checked every 6 hours and additional blood samples will be collected daily to monitor patients' lab values during their hospital stay.
Experimental: Phosphate Treatment Phase During the second year of enrollment, 50 treatment group participants will be enrolled and receive usual care plus continuous sodium phosphate or potassium phosphate (in the case of hypernatremia) which will be delivered by continuous peripheral intravenous infusion at a rate of 30 mmol every 6 hours, as long as serum phosphorus levels are ≤ 4.0 mg/dL. Phosphate infusion will be initiated as soon as possible after patient enrollment and continued for a maximum duration of 72 hours or until patient discharge from the hospital, whichever occurs sooner. Serum phosphorus levels will be checked every 6 hours, and the infusion will be paused until the next recheck if the level rises >4.0 mg/dL. Additional blood samples will be collected daily to monitor patients' lab values during their hospital stay.	Arzneimittel: Sodium Phosphate The treatment is administered via continuous peripheral intravenous infusion at a rate of 30 mmol every 6 hours, provided serum phosphorus levels remain at or below 4.0 mg/dL; it begins upon patient enrollment and continues for up to 72 hours. Andere Namen: Sodium Phosphate Injection, USP, 3mM P/mL Arzneimittel: Potassium Phosphate This treatment will be used in case of hypernatremia. The treatment is administered via continuous peripheral intravenous infusion at a rate of 30 mmol every 6 hours, provided serum phosphorus levels remain at or below 4.0 mg/dL; it begins upon patient enrollment and continues for up to 72 hours.
