Healthy Clinical Trial - Effects of Sodium Chloride or Its Substitute Salt

Status Not yet recruiting

Clinical Trial Summary

This is a prospective, monocentric, randomized trial to investigate how sodium chloride or its substitute potassium chloride acutely affects vascular function by ingestion via a salted soup. Furthermore we want to get insights on the pathophysiology by analyzing metabolism and cell function in relation to vascular reaction.

Clinical Trial Description

Some of the leading death causes in western countries are attributed to artheriosclerosis with its consequences especially cardiovascular events. Beside lifestyle risk factors such as physical inactivity, adipositas and stress, high dietary sodium intake is one of the easiest modifiable factors to reduce development and progession of artheriosclerosis. Unfortunately high sodium diet is one of the hallmarks of western diet. Epidemiologic and experimental data have provided compelling evidence that high salt and its induced elevation in bloodpressure is an important factor in the development and progression of cardiovascular disease, artheriosclerosis with its endorgan failure. To analyze the reasons for the hazardous effects of high oral sodium chloride exposure on vascular damage and a possible protective mechanism by the salt substitute potassium chloride, we intend to conduct a single-center randomized trial (ESCAPE-SALT). We aim to measure vascular function by flow mediated dilation (FMD) and dynamic vessel analysis (DVA) of retinal mircocirculation. Participants will be divided into 3 groups. Each group will be served a soup with different salt content. The salt composition is as follows: soup A (9 g sodium chloride), soup B (6 g sodium chloride plus 3 g potassium chloride), and soup C (6 g sodium chloride). The effects on blood pressure, body composition markers, electrolytes, inflammatory and metabolic response, and vascular function are measured before, 4 and 24 h after ingestion of the soup. Furthermore we will investigate the underlying mechanism by performing metabolomic, transcriptomic and proteomic anyalysis. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
