Abstract

Parenteral nutrition (PN) must be initiated as soon as possible after delivery in very low birth weight (VLBW) preterm infants in order to prevent postnatal growth failure and improve neurodevelopmental outcome. When administered early, high levels of parenteral amino acids (AA) are well tolerated and prevent negative nitrogen balance. Although proteins are the driving force for growth, protein synthesis is energy demanding. Intravenous lipid emulsions (ILE) constitute a good energy source because of their high energy density and provide essential fatty acids (FA) along with their long-chain polyunsaturated fatty acid (LC-PUFA) derivatives necessary for central nervous system and retinal development. Early supply of ILE is not associated with increased morbidity. No significant differences were found between ILE based on soybean oil only and mixed ILE containing soybean oil in combination with other fat sources, except for a reduction in the incidence of sepsis with non-pure soybean ILE, and possibly less PN-associated liver disease with mixed ILE containing some fish oil. In preterm infants glucose homeostasis is still immature in the first days of life and abnormalities of glucose homeostasis are common. VLBW infants may not tolerate high levels of glucose infusion without hyperglycemia. Administering lower levels of glucose infusion as part of full early PN seems more successful than insulin at this stage. Postpartum there is a transition period when the water and electrolyte balance may be severely disturbed and should be closely monitored. Avoiding fluid overload is critical for preventing respiratory and other morbidities

Background: A polymeric diet rich in transforming growth factor-beta 2 used as a single nutrient has been shown to induce remission in 79% of children with Crohn's disease.

Objectives: To summarize the experience of several pediatric gastroenterology units in Israel using a TGFβ2[1]-enriched polymeric diet (Modulen IBD) supplementation in children and adolescents with Crohn's disease.

Methods: In a retrospective study we reviewed the charts of 28 children with Crohn's disease (10 girls, 18 boys) who received, in addition to conventional treatment, Modulen IBD™ as a supplement to their regular nutrition. These children were compared with 18 children supplemented with standard polymeric formula (Ensure Plus®) and 18 children without formula supplementation. We recorded clinical manifestations, growth, and the Pediatric Crohn's Disease Activity Index before and after initiation of the polymeric diet.

Results: The Modulen-treated children showed a significant decrease in PCDAI[2] from 34.3 to 15.7 (P < 0.0001). A significant decrease in PCDAI was recorded also in the Ensure Plus group, from 35 to 22 (P = 0.02) but not in the non-supplemented group. Significant improvements in body mass index (P = 0.01) and erythrocyte sedimentation rate (P = 0.03) were recorded at follow-up (median 3.4 months) only in the Modulen IBD group.

Conclusions: In this cohort of children with Crohn's disease, supplementation of the diet with Modulen IBD as well as supplementation with Ensure Plus was associated with a decrease in PCDAI. The children supplemented with Modulen IBD also showed improvement in BMI[3], suggesting an additional advantage of nutritional therapy in children with this disease.
