Neuroimaging and Neuromonitoring in Critically Ill Children With Sepsis

April 9, 2021 updated by: Children's Hospital of Philadelphia
In critically ill children with severe sepsis, neurophysiologic derangements often proceed undetected and can lead to irreversible brain injury causing neurocognitive and behavioral deficits. The etiology of these impairments is unclear, however, it is likely that some of this neural injury is preventable. The overarching goal for this study is to show that acute acquired structural and microstructural brain injury occurs in critically ill children with severe sepsis, and that this injury is related to neuropsychological deficits and impaired cerebral autoregulation (CAR). Subjects will complete Magnetic resonance (MR) imaging within 2-10 days of recognition of their severe sepsis. Subjects will undergo serial interrogation of CAR for up to 10 days. CAR will be determined by the correlation of arterial blood pressure with middle cerebral artery flow velocity measured by transcranial doppler ultrasonography and cerebral oximetry derived from near-infrared spectroscopy. Subjects will also participate in a neuropsychological evaluation 6 months after enrollment to evaluate multiple domains of behavior and cognition.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

3 years to 18 years (Child, Adult)

Accepts Healthy Volunteers

Sampling Method

Probability Sample

Study Population

Children admitted to the pediatric intensive care unit (PICU) at the Children's Hospital of Philadelphia (CHOP) with severe sepsis from an extracranial source and have no history of a preexisting underlying a neurologic disorder.

Description

Inclusion Criteria:

  • Admission to the Children's Hospital of Philadelphia (CHOP) pediatric intensive care unit (PICU)
  • Males or females ages ≥ 3.5 years and ≤ 18 years on day of sepsis recognition
  • Meet published consensus criteria for severe sepsis or septic shock: a) ≥ 2 systemic inflammatory response syndrome criteria, b) suspected (based on attending physician) or confirmed systemic infection, and c) ≥ 2 or more organ system dysfunctions (severe sepsis) or cardiovascular dysfunction (septic shock).
  • An indwelling arterial catheter.
  • Parental/guardian permission (informed consent).
  • The patient and parent/guardian are fluent in English.

Exclusion Criteria:

  • History of neurologic disorder including (hypoxic ischemic injury, traumatic brain injury, epileptic encephalopathy, neurodevelopmental, neurometabolic or neurogenetic conditions, and structural brain anomalies).
  • History of cancer or undergoing treatment for cancer.
  • Meningitis or encephalitis as source of sepsis.
  • Congenital heart disease.
  • History of cardiac arrest.
  • History of extracorporeal membrane oxygenation (ECMO) cannulation.
  • Patients with contraindications to MR scanning.
  • Pregnant or lactating females.
  • Parents/guardians or subjects who, in the opinion of the Investigator, may be non-compliant with study schedules or procedures.
  • Previous enrollment in this study.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Sepsis
Children with severe sepsis or septic shock
Diagnostic test: MR imaging
Conventional structural imaging will be combined with advanced neuroimaging modalities to evaluate integrity of white matter tracts, regional brain perfusion, and the 3-dimensional volume of specific brain structures.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
MRI
Time Frame: 2-10 days
Detection of signal abnormality on the patient's brain MRI scan.
2-10 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
CAR
Time Frame: Daily for 10 days
Trends in functionality of CAR over the first 10 days of severe sepsis. Identification of the optimal blood pressure range where CAR is most functional.
Daily for 10 days
