Leptin: a Therapeutic Option for Treating Catabolic States and Malnutrition in Critically Ill Patients
Recruitment status was: Recruiting
Systemic Inflammatory Response Syndrome
|Study Design:||Observational Model: Cohort
Time Perspective: Prospective
- To assess in the intensive care setting leptin levels and their relationship to inflammatory cytokines during the course of catabolic illnesses and following recovery. [ Time Frame: 14 days, discharge from ICU or death ] [ Designated as safety issue: No ]
- To measure indices of metabolism, catabolism and ICU outcome and their associations with leptin response. [ Time Frame: 14 days, ICU discharge or death ] [ Designated as safety issue: No ]
Biospecimen Retention: Samples Without DNA
|Study Start Date:||August 2008|
|Estimated Study Completion Date:||December 2009|
|Estimated Primary Completion Date:||August 2009 (Final data collection date for primary outcome measure)|
Patients admitted to the Medical Intensive Care Unit who comply with criteria for SIRS (Systemic inflammatory response syndrome) will be enrolled into the study.
SIRS can be diagnosed when two or more of the following are present:
- Heart rate > 90 beats per minute
- Body temperature < 36 or > 38°C
- Hyperventilation (high respiratory rate) > 20 breaths per minute or, on blood gas, a PaCO2 < 32 mm Hg or mechanically ventilated
- White blood cell count < 4000 cells/mm3 or > 12000 cells/mm3 (< 4 x 109 or > 12 x 109 cells/L), or the presence of greater than 10% immature neutrophils.
Clinical parameters will be collected including: demographics, diagnosis, past medical history, past and present medications, fluids and nutrition administered, oxygenation and ventilation parameters, hemodynamic status and renal function and/or replacement therapy. Severity of illness using APACHE II score, major events during unit stay such as procedures, length of inotropic support, complications. Length of unit and hospital stay, length of ventilation, unit and hospital outcome.
Baseline leptin levels (within 8 hours of admission) will be obtained. Subsequent levels of leptin will be measured every 2 days or until discharge from the unit or death.
Serial blood count, chemistry, total protein, albumin, renal and liver function, glucose and insulin levels, lactate, total cholesterol, TSH, T3, IL-6, TNF-a, adiponectin, CRP, ESR, urine output, creatinine clearance and Nitrogen balance will be obtained.
