Impact of Dietary Phosphate Excess on Exercise Capacity and Visceral Adiposity
No phase
University of Texas Southwestern Medical Center
About 124 people
Started Sep 14, 2022
In plain words A study of phosphorus in people 18 to 80, run by University of Texas Southwestern Medical Center. It plans to enroll about 124 people at 1 US site.
Who it lists and where
Who the trial lists, as registered
Lists people 18 to 80; healthy volunteers accepted. Conditions: Physical Inactivity; Phosphate Overload; Visceral Obesity.
What it tests, as registered
Sodium Phosphate; Sodium Chloride
Registered summary
Studies in mice demonstrated that dietary phosphate (Pi) loading that mimic the level of US adult consumption leads to reduced spontaneous locomotor activity, exercise capacity, and reduced resting metabolic rate when in normal mice by impairing skeletal muscle mitochondrial function and fat oxidation. However, relevance of this findings in humans remains unknown.

Who the trial lists, as registered
Lists people 18 and older. Conditions: Pancreatitis.
Age 18 years or older
Presenting to the emergency department (ED) with acute pancreatitis meeting 2 or more characteristics of: (1) typical, persistent, severe upper abdominal pain, (2) lipase or amylase levels at least three times greater than the upper limit…
Trial treatment can be initiated within 24 hours of hospital admission
Consent can be obtained from the patient or their legal representative
The exclusion criteria are on the listing.
What it tests, as registered
Sodium Phosphate; Potassium Phosphate
Registered summary
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: *… The full summary is on the listing.

Dietary Phosphorus Intake
Registered summary
The proposed pilot feeding study aims to explore novel pathways in phosphate metabolism and identify new biomarkers, as well as to develop a compound index for assessing phosphate overload with high validity and reliability. Investigators will address the following specific aims: 1). To explore novel pathways of phosphate metabolism and assess the influence of CKD status on these metabolic pathways. 2). To identify novel biomarkers for phosphate overload that reflect changes in dietary phosphorus intake. 3). The full summary is on the listing.
