    Abstract:
    The nutritional development with three types of enteral diets during 28 days, was compared in 45 patients with malnutrition presenting an active Crohn's disease. Enteral feeding consisted of a polymeric mixture (Realmentyl) administered in addition to a normal oral diet in 11 patients; the same mixture was administered alone exclusively to 9 patients, and an elemental diet (Vivonex HN) administered exclusively to 25 patients. The total caloric intake reached, in the three groups, the mean values of 60.2, 36.9 and 33.8 kcal/kg of ideal weight/day, respectively. 33 patients also received steroids. At the end of 28 days of enteral diet, the improvement in the weight and the anthropometric measurements (muscle circumference, triceps skinfold) was significantly more marked (gain of 6.5 kg) with the supplemental polymeric mixture than with exclusive enteral diet, polymeric diet (+/- 2.0 kg) or basic (+1.2 kg). Transferrin and albumin plasma levels increased in all 3 groups, but much faster with the exclusive elemental feeding, in spite of a higher urinary urea excretion in these patients. The overall nutritional development was significantly better with supplemental polymeric feeding, and was identical in the two other groups. These results confirm that the supplemental polymeric enteral feeding is more effective, from the nutrition standpoint. With an exclusive enteral feeding, the nutritional result is appreciably the same, whether the mixture consists of polymers or basic elements.
