Nutritional support is an integral part of the supportive care of hematopoietic stem cell transplantation (HSCT) patients. Omega-3 fatty acids (n-3 FA) emulsions in parenteral nutrition (PN) may modify the inflammatory response. The purpose of this study is to compare plasma cytokine levels in children after HSCT using an n-3 FA-containing lipid emulsion (LE) and a soybean oil-based formulation in PN. A randomized double-blind controlled trial was conducted on 14 children following HSCT. Children were randomized to receive either a fish oil or a soybean oil LE. Blood samples were drawn at baseline, on Day 10 and after completion of PN to analyze plasma interleukin 1 beta (IL-1β), 2 (IL-2), 6 (IL-6), 8 (IL-8), 10 (IL-10), and tumor necrosis factor alpha (TNF-α). After 10 days of PN, there were no significant changes in interleukins levels when comparing the two groups or time points (baseline vs. Day 10 of PN). In children requiring PN >21 days, IL-10 and TNF-α levels (P ≤ 0.05) were lower in the fish-oil-containing LE group. Fish oil- and soybean oil-supplemented PN administered for at least 10 days does not cause inflammatory changes. Prolonged PN based on fish oil LE may modulate the inflammatory response.

Intra-uterine growth restriction (IUGR) may induce significant metabolic and inflammatory anomalies, increasing the risk of obesity and CVD later in life. Similarly, alterations in the adipose tissue may lead to metabolic changes in children with a history of extra-uterine growth restriction (EUGR). These mechanisms may induce alterations in immune response during early life. The aim of the present study was to compare pro-inflammatory markers in prepubertal EUGR children with those in a reference population. A total of thirtyeight prepubertal children with a history of EUGR and a reference group including 123 healthy age-and sex-matched children were selected. Perinatal data were examined. In the prepubertal stage, the concentrations of inflammatory biomarkers were measured in both groups. The serum concentrations of C-reactive protein (CRP) and plasma concentrations of hepatocyte growth factor (HGF), IL-6, IL-8, monocyte chemotactic protein type 1 (MCP-1), neural growth factor, TNF-a and plasminogen activator inhibitor type 1 were determined. The plasma concentrations of inflammatory biomarkers CRP, HGF, IL-8, MCP-1 and TNF-a were higher in the EUGR group than in the reference group (P, 0·001). After adjustment for gestational age, birth weight and length, blood pressure values and TNF-a concentrations remained higher in the EUGR group than in the reference group. Therefore, further investigations should be conducted in EUGR children to evaluate the potential negative impact of metabolic, nutritional and pro-inflammatory changes induced by the EUGR condition.
