Tracking microRNA fingerprints in children with sepsis

Modulation of Molecular Fingerprinting in Pediatric Sepsis

Observational Phoenix Children's Hospital · NCT02055105

This project will test whether small circulating microRNA markers can be detected in children with sepsis and whether their levels change with treatment.

What this trial studies

This observational study will collect blood, urine, and buccal swab samples from pediatric patients with suspected sepsis at five time points to measure circulating microRNA levels and compare them to current biomarkers. Enrolled patients will receive standard clinical care, including antimicrobials and organ support as needed, while clinical data are recorded to calculate severity scores such as PRISM III and TISS-28. Samples will be stored at -80°C and analyzed to determine sensitivity, specificity, and correlations between microRNA expression, treatment response, and outcomes. All patient data will be de-identified and entered into a secure database for analysis to generate pilot data for future studies.

Who should consider this trial

Good fit: Children aged 1 through 18 years admitted to the pediatric intensive care unit with suspected sepsis or who develop sepsis during admission and enrolled within 24 hours of starting antibiotics are eligible.

Not a fit: Infants under 1 year, adults over 18, patients not admitted to the PICU, or those enrolled more than 24 hours after antibiotic initiation are not eligible and would not benefit from this protocol.

Why it matters

Potential benefit: If successful, the work could lead to better biomarkers that help detect sepsis earlier or monitor treatment response in children.

How similar studies have performed: Previous adult and some pediatric studies have reported promising correlations between specific microRNAs and sepsis severity, but clinical utility as diagnostic or treatment-monitoring tools remains unproven.
