The investigators propose a prospective randomized clinical trail to evaluate the impact of intensive medical nutrition therapy (IMNT) in patients with acute respiratory distress syndrome (ARDS) or acute lung injury (ALI) on short and long-term outcomes. Participant's (N = 200) will be randomized to receive either standard care (SC e.g. ad lib feeding of standard food) or IMNT provided early as enteral nutrition (EN) and continued as intensive diet therapy tailored to maximize oral intake until hospital discharge. Primary outcomes evaluated include infections while hospitalized, immune parameters (CD4 and CD8 cells, serum IL-10 and leptin levels, numbers of T regulatory cells and markers for T cell anergy), days on mechanical ventilation, in the ICU and hospital , and changes in fat free mass(measured by dual energy x-ray absorptiometry), weight, muscular weakness (measured as hand grip strength), fatigue (measured as distanced traveled in 6-minute walk) and pulmonary function.

Further study details as provided by University of Illinois at Chicago:

Primary Outcome Measures:
  • Infection [ Time Frame: Assessed daily from study enrollment through hospital discharge, an average of 3 weeks ]
    All new infections that occurred (including blood, wound, sputum, urinary tract and pulmonary) from enrollment through hospital discharge recorded in the medical record were counted

Secondary Outcome Measures:
  • Length of Hospital Stay [ Time Frame: days in hospital ]
    The total number of days the patient is in the hospital

  • Days on Mechanical Ventilation [ Time Frame: days ]
    the total number of days requiring mechanical ventilation while hospitalized

  • Death [ Time Frame: date of occurence ]
    The date of death for all participants that die between enrollment and their final data collection, 24 weeks following hospital discharge

Other Outcome Measures:
  • Immune Parameters [ Time Frame: baseline and weekly while hospitalized ]
    Markers of immune response (including IL-6, IL-10, adiponectin, leptin, CRP, TNF, CD4/CD8 and HLA/CD14

Enrollment: 78
Study Start Date: July 2009
Study Completion Date: June 2013
Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
intensive medical nutrition
participants will receive intensive medical nutrition from hospital admission to discharge
Behavioral: intensive medical nutrition
provision of participants energy and protein needs via enteral, parenteral nutrition from hospital admission to discharge
participants will not receive intensive nutritional support from hospital admission to discharge
Other: control
participants will receive standard care for nutrition received from hospital admission to discharge

Detailed Description:
This study was terminated early due to greater deaths occurring in the intervention group vs the control group. There were a total of 22 deaths, 16 in the intervention and 6 in the control.

Ages Eligible for Study:   18 Years to 90 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria: Adult patients (> 18 years) with a diagnosis of acute lung injury, with viable GI function for enteral feeding
