NCT ID: NCT06007157 Recruiting - Blood Pressure Clinical Trials

Sodium Glucose Cotransporter-2 Inhibitors and Salt-sensitivity in Type 2 Diabetes

SALT
Start date: March 1, 2023
Phase: N/A
Study type: Interventional

The goal of this interventional study is to test whether sodium-glucose cotransporter 2 inhibitors (SGLT2i) reduce the effects of high dietary sodium intake in patients with type 2 diabetes. Participants will undergo a dietary intervention consisting of a week of high-sodium diet, followed by a week of low-sodium diet. At the end of each week the patients will undergo: - 24-h ambulatory blood pressure measurement; - 24-h urine collection; - bioimpedance analysis for body composition determination; - blood and urine tests. The study will compare patients treated with SGLT2i and patients not treated with SGLT2i to test whether the treatment reduces the effects of high sodium intake on blood pressure, body composition and biochemical variables.

Ketone Ester and Acute Salt (KEAS) in Young Adults

KEAS
Start date: March 24, 2023
Phase: N/A
Study type: Interventional

Most Americans consume excess dietary salt based on the recommendations set by the American Heart Association and Dietary Guidelines for Americans. High dietary salt impairs the ability of systemic blood vessels and the kidneys to control blood pressure, which contributes to excess salt consumption being associated with increased risk for chronic kidney disease and cardiovascular disease, the leading cause of death in America. There is a critical need for strategies to counteract the effects of high dietary salt as consumption is likely not going to decrease. One promising option is ketones, metabolites that are produced in the liver during prolonged exercise and very low-calorie diets. While exercise and low-calorie diets are beneficial, not many people engage in these activities. However, limited evidence indicates that ketone supplements improve cardiovascular health in humans. Additionally published rodent data indicates that ketone supplements prevent high salt-induced increases in blood pressure, blood vessel dysfunction, and kidney injury. Our human pilot data also indicates that high dietary salt reduces intrinsic ketone production, but it is unclear whether ketone supplementation confers humans protection against high salt similar to rodents. Therefore, the investigators seek to conduct a short-term high dietary salt study to determine whether ketone supplementation prevents high dietary salt from eliciting increased blood pressure, blood vessel dysfunction, and kidney injury/impaired blood flow. The investigators will also measure inflammatory markers in blood samples and isolate immune cells that control inflammation. Lastly, the investigators will also measure blood ketone concentration and other circulating metabolites that may be altered by high salt, which could allow us to determine novel therapeutic targets to combat high salt.

NCT ID: NCT05397054 Recruiting - Hypertension Clinical Trials

Intervention for Monitoring of Salt Intake in Hypertensive Patients

Start date: January 10, 2022
Phase: N/A
Study type: Interventional

Sodium is an essential nutrient for humans, but excessive sodium consumption is causally associated with high blood pressure and increase risk of cardiovascular diseases. Dietary sodium consumption of greater than the recommended daily amount of 5 grams of salt or 2,000 mg of sodium is a major risk factor for CVD-related mortality. From recent national survey, Thai people had consumed more than 9.1 g of salt per day, which was nearly two times above WHO reference level. Dietary salt reduction was unsuccessful because of lacking awareness, and the higher threshold to detect salt taste in chronic high salt ingestion. To create awareness in the community, we should be educated, managed the environmental for salt reduction, and used salt meter to detect sodium content in daily food. This study aimed to compare the efficacy of intervention; education, reformulation, environmental change and used salt meter compared with standard treatment alone in terms of salt intake reduction and blood pressure.

NCT ID: NCT05048225 Recruiting - Pregnancy Related Clinical Trials

Dietary Salt During Pregnancy and Maternal Vascular Function

Investigating Salt Taste Threshold in Patients Being Investigated for Primary Hyperaldosteronism Before and After Treatment.

AldoSalt
Start date: January 2021
Phase:
Study type: Observational

This study looks at how hypertensive patients, with high levels of aldosterone (hyperaldosteronism) differ from hypertensive patients without hyperaldosteronism with regards to markers of salt appetite. It also looks at how salt appetite changes after treatment of hyperaldosteronism. Salt makes food taste good and when our bodies need salt our brains make us like salty food even more. A high salt diet contributes to hypertension and a low salt diet is an important aspect of the treatment of hypertension. Unfortunately patients find it difficult to adhere to a low salt diet. Aldosterone is produced by the adrenal glands, its release is stimulated by a salt need and it has been shown, in rodent models, to activate pathways in the brain which drive a salt appetite. Mice with enhanced activity of the aldosterone pathway in the brain become hypertensive due to increased salt intake. Hyperaldosteronism, in humans, results in hypertension. The contribution of salt appetite, as opposed to the effect of aldosterone on the kidney's retention of salt and other systems, is unknown. Human studies have shown that when a human has a salt appetite, the concentration at which they can detect the taste of salt reduces, they increase their preference for salty food, and they consume more salt. When hyperaldosteronism is suspected in a hypertensive patient, they attend hospital for a day of investigations. Patient who are shown to have hyperaldosteronism have subsequent visits for imaging of their adrenals and sampling of blood from the adrenal vein to diagnose aldosterone producing adenomas (small tumours) which may be removed surgically, if not suitable for surgery, the hyperaldosteronism is treated with medication. This study will recruit hyperaldosteronism patients to investigate the effect of aldosterone on salt appetite by testing salt taste threshold, salt taste preference and intake before and after treatment.

Impact of Self-monitoring of Salt Intake by Salt Meter in Hypertensive Patients

SMAL-SALT
Start date: July 11, 2017
Phase: N/A
Study type: Interventional

Hypertension is one of the most common chronic medical conditions. The concerned sequelae are the cardiovascular complications, especially acute myocardial infarction and stroke. In Thailand, the incidence of hypertension is increasing each year. Many clinical studies found that salt intake over the reference level (>5 g/day) would result in elevated blood pressure (BP) and long-term morbidity. Dietary salt reduction campaigns were unsuccessful, in part, due to time limitation in the clinic, lacking of awareness, and the higher threshold to detect salt taste in chronic high salt ingestion. Salt meter is a device used to detect sodium content in daily food. It will facilitate monitoring and control of salt intake. The 24-hour urinary sodium excretion is an acceptable method to reflect the quantity of sodium intake. This study aimed to compare the efficacy of salt meter plus dietary education compared with education alone in terms of salt intake reduction, blood pressure, salt taste sensitivity, and vascular consequence.

Uric Acid, Klotho and Salt Sensitivity in Young Adults Born Preterm

PEPC3
Start date: September 2, 2020
Phase: Early Phase 1
Study type: Interventional

The purpose of this research is to learn about how salt in the diet influences blood pressure in young adults who were born prematurely.

NCT ID: NCT04021355 Recruiting - Obesity Clinical Trials

Timing of Sodium Intake and Nocturnal Sodium Excretion and Blood Pressure in Obese African Americans

Start date: July 14, 2020
Phase: N/A
Study type: Interventional

Experimental data have shown that timing of sodium intake impacts diurnal patterns of sodium excretion. The purpose of this study is to test the hypothesis that the time of day for salt intake impacts (1) blood pressure rhythms and urinary sodium excretion and (2) circadian timing of factors responsible for blood pressure regulation and cardiometabolic health in obese individuals. These studies will address two aims. The first aim will test the hypothesis that limiting high salt intake prior to sleep increases day-night differences in blood pressure, improves timing of urinary sodium excretion, and improves metabolic risk factors. The second aim will test the hypothesis that limiting high salt intake prior to sleep preferentially improves rhythmicity in peripheral vs. central circadian clock factors linked to renal sodium handling. The proposed hypothesis-driven studies will determine how timing of sodium intake affects diurnal blood pressure and circadian timing of factors responsible for blood pressure control and metabolic health, with the ultimate goal of identifying novel strategies to treat nocturnal hypertension and metabolic disease in obesity.

Study With an Innovative Equipment to Monitor and Control SALT During Cooking

iMC_SALT
Start date: June 1, 2019
Phase: N/A
Study type: Interventional

In this study, the researchers will evaluate the efficacy of an intervention using the SALT CONTROL H instrument (an innovative equipment to monitor and control salt) in workers at the University of Porto to reduce dietary salt intake. This is a randomized clinical trial with intervention conducted according to good clinical practice guidelines. The researchers will randomize 260 workers who meet the eligibility criteria and are enrolled in occupational health appointments. Prior to the intervention, the informed consent of the participants will be obtained and those who agree to participate will be allocated randomly in one of the two arms of the study (control or intervention), with balance of baseline characteristics (sex and hypertension). The intervention will last for 8 weeks, an individual session of presentation of SALT CONTROL H will be carried out, with explanation of how the equipment works in the culinary preparation with an adequate salt content, will be used an illustrative video and recipes with an adequate salt content; use of SALT CONTROL H at home by the participant to control the use of salt during the cooking process; supervision and enhancement of the use of equipment; daily occurrence log; and the application of a satisfaction questionnaire on the use of SALT CONTROL H. A leaflet will also be delivered about "The new Food Wheel, a guide to the daily food choice!". Control Group: No intervention will be carried out except the provision of a leaflet on "The new Food Wheel, a guide to the daily food choice!" to the participants. Baseline, at the 4th and 8th intervention weeks, and 6 months after intervention analysis will cover the following domains: urinary sodium excretion corresponding to a 24 hour urine collection as a proxy for salt intake; 24-hour urinary potassium excretion, sodium:potassium ratio, systolic and diastolic blood pressure, and anthropometric measurements. Urine samples will be collected according to standardized procedures and analyzed by a certified laboratory. Secondary data such as satisfaction questionnaire, daily use of equipment, iodine analysis of salt used and excreted in urine 24h, hydration status, analysis of quality of life and quality of diet will also be analyzed, as well as intestinal microbiota.
