Glucose Control in Severely Burned Patients

March 24, 2022 updated by: Dr. Marc Jeschke, Sunnybrook Health Sciences Centre

Glucose Control in Severely Burned Patients: Mechanisms and Therapeutic Potential

The central aim of this application is to determine whether improved outcomes with tight euglycemic control are due to insulin-specific responses. The investigators hypothesize that improving insulin resistance will lead to decreased inflammatory and hypermetabolic responses, as well as restored glucose metabolism, and so result in improved clinical outcome of severely burned patients.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
45

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

18 years to 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
No Intervention: Control
Experimental: Metformin
Drug: Metformin
Metformin 850 mg q. 8 hours will be given to decrease blood glucose to 130-140 mg/dl.
Experimental: Insulin
Drug: Humulin R
Humulin R (U-100) will be given i.v. The dose given will be adjusted in order to achieve a blood glucose level of 130-140 mg/dl.

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
Perform oral glucose tolerance test
Time Frame: at 1-2 months post-admission, up to 6 months
Standard fasting oral glucose tolerance test with an intake of 75 g of glucose. Subsequent measurements (in mg/dl) of glucose in blood, insulin and c-peptide will be conducted over 2 hours.
at 1-2 months post-admission, up to 6 months
Perform oral glucose tolerance test
Time Frame: assessed at discharge (1-4 months post admission depending on the severity of injury)
Standard fasting oral glucose tolerance test with an intake of 75 g of glucose. Subsequent measurements (in mg/dl) of glucose in blood, insulin and c-peptide will be conducted over 2 hours.
assessed at discharge (1-4 months post admission depending on the severity of injury)

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
Measure concentrations of serum cytokines
Time Frame: weekly until discharge (1-4 months post admission depending on severity of injury)
Inflammatory response will be assessed by measuring the concentrations (in pg/ml)of a panel of serum cytokines (IL-1, IFN, TNF etc.) using the Bio-Plex 17-Plex Suspension assay.
weekly until discharge (1-4 months post admission depending on severity of injury)
Record the episodes of sepsis
Time Frame: daily until discharge (1-4 months post admission depending on severity of injury)
Patients will be assessed daily for episodes of sepsis. The total number of episodes over the course of hospital stay will be recorded.
daily until discharge (1-4 months post admission depending on severity of injury)
Record the episodes of Pneumonia
Time Frame: daily until discharge (1-4 months post admission depending on severity of injury)
Pneumonia is defined by new progressive and persistent infiltrate, consolidation or cavitations, inhalation injury based on chest X-ray. We will also follow the guidelines provided by the American Burn Association on the definition of Pneumonia in burn patients. Change in sputum (purulent or increased) will also be recorded.
daily until discharge (1-4 months post admission depending on severity of injury)
