简要总结
A study conducted in the laboratory revealed the existence of a "window" during which patients with renal failure appreciate the protein-rich foods. This period, located immediately after the dialysis, is likely related to the purification of plasma products resulting from protein catabolism. It therefore appears necessary to understand the mechanisms that may explain these changes by measurements of ghrelin (orexigenic hormone), leptin (anorectic hormone) and plasma amino acids.
详细描述
In 24 patients with renal failure treated by hemodialysis, it is evaluated (at 8:00 am and at 11:00 am), a day without hemodialysis and another day after the hemodialysis:
- Hunger sensation,
- Olfactory liking assessed separately for 6 foods (2 carbohydrate-, 2 fat- and 2 protein-rich foods) and 2 non-alimentary products,
- Food wanting evaluated by the sequential presentation of 18 images of food (6 fat-, 6 carbohydrate- and 6 protein-rich foods),
- Two blood samples for the assays of leptin, ghrelin, creatinine, albumin and pre-albumin as well as plasma amino acids.
24 healthy subjects are also evaluated in order to compare the results from patients to those of control subjects.

结局指标
主要结局
Amount of wanting for protein-rich foods
时间窗: 20 min (from 8:00 to 8:20 am) and 20 min (from 11:00 to 11:20 am)
The wanting is determined after the successive presentation (for ten seconds) of 18 pictures of food. For each food the question is "at the present time, do you want to eat this food? ". For each photo, subjects place a vertical line on a 10 cm horizontal line bounded at its ends by "no desire" and "extremely envy" (visual analog scale).The wanting for proteins is the mean score for the desire to eat protein-rich foods.
次要结局
- Concentrations of the plasma amino-acids(8:30 am and 11:30 am)
