This study investigates if pancreatic enzymes in combination with oral nutritional supplement can improve nutrient bioavailability in older people with malnutrition or at risk of malnutrition.
This study investigates whether adding digestive pancreatic enzymes to oral nutritional supplements (ONS) can improve nutrient absorption in older adults at risk of malnutrition. While ONS are commonly recommended, their effectiveness is often limited due to age-related declines in exocrine pancreatic function, leading to reduced enzyme secretion. Studies indicate that pancreatic lipase levels decline with age, potentially impairing nutrient digestion and absorption. The study proposes using pancrelipase (Zenpep®), an FDA-approved pancreatic enzyme replacement therapy, to enhance nutrient bioavailability. The randomized, placebo-controlled trial will assess whether pancrelipase improves postprandial levels of amino acids, fatty acids, and glucose in hospitalized patients at nutritional risk. The study aims to determine if pancreatic enzyme supplementation can enhance nutrient absorption and provide a novel strategy for managing malnutrition in older adults without diagnosed exocrine pancreatic insufficiency (EPI). If successful, this approach could improve clinical outcomes, reduce healthcare costs, and enhance quality of life.

RECRUITINGIncremental area under the curve of total branched-chained amino acid concentration
Evaluation of the incremental area under the curve (iAUC) of total branched-chain amino acid (BCAA) concentration in blood, including leucine (μmol/L), isoleucine (μmol/L), and valine (μmol/L). The iAUC represents the time-dependent changes in BCAA levels and is used to assess metabolic responses.
Time frame: From oral nutritional supplements (ONS) consumption over 3 hours postprandial, specifically in 5 time points (T0 ONS consumption and after 30, 60, 120 and 180 minutes)
Incremental area under the curve of essential amino acids (EAAs)
Evaluation of the incremental area under the curve (iAUC) of essential amino acids (EAAs) in plasma, expressed in micromoles per liter (μmol/L). The iAUC reflects the time-dependent changes in EAAs concentrations and is used to assess metabolic responses.
Time frame: From ONS consumption over 3 hours postprandial, specifically in 5 time points (T0 ONS consumption and after 30, 60, 120 and 180 minutes)
Incremental area under the curve of total amino acids
Evaluation of the incremental area under the curve (iAUC) of total amino acids in plasma, expressed in micromoles per liter (μmol/L). The iAUC reflects the time-dependent changes in total amino acid concentrations and is used to assess metabolic responses.
Time frame: From ONS consumption over 3 hours postprandial, specifically in 5 time points (T0 ONS consumption and after 30, 60, 120 and 180 minutes)
Incremental area under the curve of free fatty acids
Evaluation of the incremental area under the curve (iAUC) of free fatty acids in plasma, expressed in micromoles per liter (μmol/L). The iAUC reflects the time-dependent changes in free fatty acid concentrations and is used to assess metabolic responses.
Time frame: From ONS consumption over 3 hours postprandial, specifically in 5 time points (T0 ONS consumption and after 30, 60, 120 and 180 minutes)

Incremental area under the curve of triglycerides
Evaluation of the incremental area under the curve (iAUC) of triglycerides in plasma, expressed in millimoles per liter (mmol/L). The iAUC reflects the time-dependent changes in triglycerides concentrations and is used to assess metabolic responses.
Time frame: From ONS consumption over 3 hours postprandial, specifically in 5 time points (T0 ONS consumption and after 30, 60, 120 and 180 minutes)
Water load satiety test (WLST)
Values of a modified water load satiety test (WLST), a questionnaire of 5 sub-scores on a scale of 1-100. We will report both the sum of the scores and the 5 individual sub scales will be reported. Participant rate pre-and postprandial intensity of symptoms for fullness, hunger, abdominal discomfort, bloating, and nausea on a 0-100 mm visual analogue scale where 0 is none, and 100 is severe
Time frame: From ONS consumption over 3 hours postprandial, specifically in 5 time points (T0 ONS consumption and after 30, 60, 120 and 180 minutes)
Exploratory subgroup analysis
Exploratory subgroup analyses to test their effect on the primary outcome (incremental area under the curve (AUC) of total branched-chained amino acid concentration in the blood) will be performed. These will be assessed using a t-test on the differences between pancrelipase and placebo for each patient. Groups are based on the subgroup including median age \[years\], malnutrition risk \[Nutritional Risk Screening 2002 total score\], median weight \[kg\], sex \[male/female\], prior history of gastrointestinal side effects \[yes/no\], median fecal elastase \[μg/g\]
Time frame: After study completion, within 1 year
Incremental area under the curve of glucose
Evaluation of the incremental area under the curve (iAUC) of glucose in plasma, expressed in millimoles per liter (mmol/L). The iAUC reflects the time-dependent changes in glucose concentrations and is used to assess metabolic responses.
Time frame: From ONS consumption over 3 hours postprandial, specifically in 5 time points (T0 ONS consumption and after 30, 60, 120 and 180 minutes)
