Detailed Description
Fifty patients identified as having poor nutrition by the following criteria:
- Average of Serum Albumin for the consecutive two months prior to inclusion </= 3.7 g/dl and the serum albumin for the previous month is < 3.7 mg/dl.
one of the four following criteria:
- Protein catabolic rate less than 1.0 g/kg/d on at least 2 occasions over the past 6 months
- Progressive unintentional weight loss more than 2.5% of the initial or ideal body weight and/or patients who are less than 90% of Standard Body Weight
- Subjective Global Assessment Score consistent with Moderate to Severe Malnutrition within the last month
Biochemical parameters of malnutrition defined by 1 of 2 of the following measurements (if available) over the consecutive two months prior to inclusion:
- Serum transferrin concentration less than 225 mg/dl
- Serum prealbumin concentration less than 32 mg/dl
will be randomized to receive either ProStat 64 or placebo for 3 months. At Baseline a Dexa for lean body mass and labs for BUN, creatinine, glucose, serum albumin, prealbumin and C-reactive protein will be drawn. Cholesterol and transferrin will be recorded from the regular monthly labs if available. In addition, a protein catabolic rate will be calculated and a SGA will be completed.
Patients will take the supplement/placebo twice a day. Measurements will be repeated at month 3. At the end of these measurements, all patients will be switched to open label ProStat64 for an additional 3 months. At month 6 all study procedures/labs are repeated and the study is complete.
