Ultrasound Stimulation for Inflammation and Healthy Subjects
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to explore whether ultrasound waves can trigger an anti-inflammatory response by targeting specific nerves, namely the splenic and cervical vagus nerves. Researchers are testing different ultrasound levels to determine which best reduces inflammation without medication. The study seeks healthy volunteers who have no chronic conditions and are not taking any medications that affect inflammation. As an unphased trial, it offers participants a unique opportunity to contribute to groundbreaking research on reducing inflammation without medication.
Will I have to stop taking my current medications?
Yes, you will need to stop taking anti-inflammatory or immunomodulatory medications, as well as anticoagulant or antiplatelet drugs, at least one week before the ultrasound procedure.
What prior data suggests that this ultrasound stimulation is safe for healthy subjects?
Research shows that ultrasound therapy is generally safe and easy to handle. Studies have found that low-intensity pulsed ultrasound (LIPUS) can help reduce swelling in various conditions. Clinical trials have successfully used it to decrease inflammation. This method is considered affordable, safe, and easy to use.
Other studies tested ultrasound on animals, where it reduced swelling without causing serious side effects. While these results are encouraging, it's important to remember that what works in animals doesn't always work the same way in humans.
Overall, current evidence suggests that using ultrasound to reduce inflammation is a safe option. The treatment has been used in different situations without major problems. However, like any treatment, rare reactions might occur, so discussing any concerns with the trial team is always a good idea.12345Why are researchers excited about this trial?
Researchers are excited about using ultrasound stimulation for inflammation because it offers a non-invasive way to potentially reduce inflammation by targeting the body's internal systems. Unlike standard anti-inflammatory treatments that often rely on medications like NSAIDs or corticosteroids, this method uses pulsed ultrasound to stimulate specific areas such as the splenic hilum and cervical vagus nerve. This innovative approach could lead to fewer side effects and more precise control over inflammation, making it a promising alternative to traditional drug therapies.
What evidence suggests that ultrasound-induced anti-inflammation could be effective for reducing inflammation?
Research has shown that low-intensity ultrasound can reduce swelling and aid healing for various conditions. This trial will explore different ultrasound treatments, including those with varying mechanical indices, to assess their effects on inflammation. Studies have found that ultrasound can boost the body's immune system, helping manage swelling. For instance, research on animals demonstrated that ultrasound improved recovery in rats with spinal cord injuries by reducing swelling. Another study discovered that ultrasound can trigger the release of substances that help control swelling. Overall, these findings suggest that ultrasound might be a promising way to manage swelling in humans.36789

Are You a Good Fit for This Trial?
This trial is for healthy adults aged 25-50 who speak English, can follow the study's rules, and will be available throughout. They must have normal blood counts and organ function. People with bleeding disorders, heart issues like arrhythmias or high blood pressure needing multiple drugs, recent drug use (anti-inflammatories, anticoagulants), infections, allergies to ultrasound gel, implants like pacemakers or a history of certain surgeries cannot join.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Treatment
Participants receive pulsed ultrasound stimulation targeting the splenic nerve or the cervical vagus nerve at different intensities
Follow-up
Participants are monitored for changes in immune cell concentrations and cytokine levels post-ultrasound treatment
What Are the Treatments Tested in This Trial?
Interventions
- Ultrasound-induced Anti-inflammation
Trial Overview
The study tests if pulsed ultrasound aimed at nerves in the neck or near the spleen can reduce inflammation in healthy people. It checks two things: how intense the ultrasound should be and exactly where it should target.
How Is the Trial Designed?
2
Treatment groups
Active Control
Individuals will receive pulsed ultrasound with a mechanical index of 1.4 delivered to the splenic hilum and the cervical vagus nerve. The two doses will be administered in separate visits with min. 14 days between each stimulation.
In Subgroup 1, individuals will receive pulsed ultrasound with a mechanical index of 0.6 and 1.4 delivered to the splenic hilum. In Subgroup 2, individuals will receive pulsed ultrasound with a mechanical index of 1.0 and 1.8 delivered to the splenic hilum. In Subgroup 3, individuals will receive sham treatment and pulsed ultrasound with a mechanical index of 1.4 delivered to the splenic hilum. In all Subgroups, the two doses will be administered in separate visits with min. 14 days between each stimulation.
