Study Summary

This is a randomized, sham-controlled pilot study that will assess the safety and feasibility of splenic focused pulsed ultrasound treatment on burn wound healing time in 24 subjects (12 active ultrasound and 12 sham controls).

Eligibility Criteria

Inclusion

Inclusion Criteria:

  • Able to provide written informed consent

Exclusion

Exclusion Criteria:

  • Wounds determined by study clinicians to be ineligible, including those that mayinhibit access to the spleen for the ultrasound procedure

  • Participating in another research study that may affect the conduct of results ofthis study

  • BMI > 30

  • Previous surgery of the spleen, esophagus, stomach, duodenum, or liver,including splenectomy

  • End stage renal disease and/or uremia

  • Implanted pacemaker or cardioverter/debribrillator

  • History of unstable angina, angioplasty or coronary arterial by-pass graftingsurgery

  • History of stroke or TIA

  • Untreated thrombosis or bleeding disorders

  • Currently implanted vagus nerve stimulator

  • Currently implanted spinal cord stimulator or other chronically implantedelectronic device

  • Receiving oral, topical, rectal, or parenteral corticosteroids in an unstable dose 4weeks prior to baseline visit

  • Any immunosuppressive or cytotoxic medications

  • Clinically relevant history of alcohol or drug abuse as determined by theinvestigator including:

  • alcohol consumption within 4 days of the baseline visit

  • tobacco or nicotine product use within the past 1 month

  • recreational drug use within the past 1 month

Study Description

The Central Hypothesis underlying this study is that splenic ultrasound stimulation activates the splenic anti-inflammatory pathway, thereby producing reduction in circulating macrophage cytokine production, reduction of neutrophil invasiveness, or induction of phenotypic transition in circulating immune cells (e.g., M1 to M2 transition in macrophages) in patients with partial thickness wounds that cover <20% body surface area.

Approximately 24 subjects will participate in this study. Male and female subjects of all races and ethnicities will be recruited for study from the ethnically diverse patient population of the LAC+USC Burn Center from the surrounding area.

Phase 0

Burn wound subjects will be screened and enrolled at the LAC+USC Burn Center located in Los Angeles, California. No other sites, neither regional nor outside of the United States are going to participate in enrollment of subjects.

A General Electric LOGIQ E10 ultrasound machine with a C1-6-XD clear probe, will be used to selectively deliver pulsed ultrasound to the spleen.

12 months.

28 days or until healed (whichever comes first)
