Brief Summary:
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.

Condition or disease
Renal Failure

Detailed Description:

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.

Primary Outcome Measures :
  1. Amount of wanting for protein-rich foods [ Time Frame: 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.

Secondary Outcome Measures :
  1. Concentrations of the plasma amino-acids [ Time Frame: 8:30 am and 11:30 am ]
    Variation in concentrations of amino-acids during the morning a day with hemodialysis and a day without hemodialysis, and comparison with plasma AAs from healthy subjects
