Glucose Control in Severely Burned Patients

Overview[ - collapse ][ - ]

Purpose 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.

Current Primary Outcome Measures
  • Perform oral glucose tolerance test [Time Frame: at 1-2 months post-admission, up to 6 months] [Designated as safety issue: No]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.
  • Perform oral glucose tolerance test [Time Frame: assessed at discharge (1-4 months post admission depending on the severity of injury)] [Designated as safety issue: No]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.
Current Secondary Outcome Measures
  • Measure concentrations of serum cytokines [Time Frame: weekly until discharge (1-4 months post admission depending on severity of injury)] [Designated as safety issue: No]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.
  • Record the episodes of sepsis [Time Frame: daily until discharge (1-4 months post admission depending on severity of injury)] [Designated as safety issue: No]Patients will be assessed daily for episodes of sepsis. The total number of episodes over the course of hospital stay will be recorded.
  • Record the episodes of Pneumonia [Time Frame: daily until discharge (1-4 months post admission depending on severity of injury)] [Designated as safety issue: No]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.
