Brief Summary:
This study evaluates the safety and effectiveness of focused ultrasound spleen neuromodulation in patients with septic shock, a life-threatening condition characterized by excessive inflammation and organ dysfunction. The primary objective is to determine whether non-invasive, focused ultrasound stimulation of the spleen can reduce circulating inflammatory cytokine levels in this patient population.
Eligibility Criteria:
Adults aged 18 years or older Diagnosed with septic shock and admitted to the ICU within 24 hours Expected to require intensive care for at least 72 hours
Study Protocol:
Participants will be randomly assigned to one of two groups:
Intervention Group: Will receive standard septic shock care plus twice-daily focused ultrasound stimulation over the spleen for five days, using a portable device.
Control Group: Will receive standard septic shock care alone. Blood samples will be collected at baseline, Day 3, and Day 5 to measure inflammatory cytokine levels, including TNF-α, IL-1β, IL-6, and IL-10. Additional assessments will include lymphocyte subpopulations, organ function scores, ICU length of stay, 28-day mortality, and adverse events.
Outcome Measures:
Primary: Change in levels of inflammatory cytokines on Day 3 and Day 5. Secondary: Changes in organ function (SOFA score), ICU length of stay, 28-day survival, and safety/tolerability of the intervention.
Detailed Description:
This randomized, controlled pilot study investigates the safety and efficacy of focused ultrasound neuromodulation of the spleen in adult patients diagnosed with septic shock. Participants will be randomized into two groups: one receiving standard of care and the other receiving additional targeted spleen stimulation via focused ultrasound. The intervention involves twice-daily sessions over five days, utilizing a portable device designed to deliver precise, non-invasive ultrasound energy to the splenic region. The rationale for targeting the spleen stems from its role in immunomodulation, particularly in the regulation of inflammatory cytokines involved in septic shock pathophysiology.
Blood samples will be systematically collected at baseline, Day 3, and Day 5 to quantify serum levels of key inflammatory cytokines, including tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), interleukin-6 (IL-6), and interleukin-10 (IL-10), using validated immunoassays. In addition, lymphocyte subpopulations will be analyzed via flow cytometry to assess immune cell dynamics. Organ dysfunction will be evaluated using the Sequential Organ Failure Assessment (SOFA) score at specified time points to monitor changes in organ status. Data on ICU length of stay and 28-day mortality will be collected to evaluate clinical outcomes. Adverse events related to the intervention will be documented to assess safety and tolerability.
By investigating the immunomodulatory effects of focused ultrasound spleen neuromodulation, this study aims to establish preliminary safety and efficacy data for a potentially transformative therapeutic modality in septic shock management.
