Effects of critical illness on plasma PYY and CCK concentrations. Effects of critical illness on plasma (a) PYY and (b) CCK concentrations during fasting and duodenal nutrient infusions of 1 kcal/minute (ICU patients, n = 9; healthy subjects, n = 13) and 2 kcal/minute (ICU patients, n = 10; healthy subjects, n = 11) compared with healthy age- and gender-matched control group. ICU patients: closed diamond, solid line; healthy subjects: open circle, solid line. Fasting and nutrient-stimulated PYY and CCK concentrations were higher in patients compared with the healthy control group. *P < 0.05, **P < 0.001 versus healthy subjects. CCK, cholecystokinin; ICU, intensive care unit; PYY, peptide YY.
