The aggressive radiotherapy and chemotherapy used in conditioning regimens for children with leukaemia undergoing bone marrow transplantation (BMT) cause a severe catabolic state. Total parenteral nutrition (TPN) is indispensable in the management of these patients. 25 children with leukaemia undergoing BMT were studied to evaluate the efficacy of TPN and the value of anthropometric parameters and biochemical variables (albumin, retinol-binding protein and prealbumin) in monitoring nutritional status in the critical post-BMT phase. The complications of TPN were mainly metabolic, generally mild and easily controlled. The hyperalimentation solution and infusion line were not responsible for infection in any patient. The marked variations in anthropometric parameters and albumin expected in such patients were not observed in our children due to the nutritional support given. Prealbumin and retinol-binding protein showed statistically significant, positive variations (P less than 0.01), thus proving sensitive indices of the response to nutritional repletion.

Epidemiological studies demonstrated that adverse environmental factors leading to intrauterine growth retardation (IUGR) and low birth weight may predispose individuals to increased risk of metabolic syndrome. In rats, we previously demonstrated that adult male IUGR offspring from prenatal 70% food-restricted dams throughout gestation (FR30) were predisposed to energy balance dysfunctions such as impaired glucose intolerance, hyperleptinemia, hyperphagia and adiposity. We investigated whether postweaning moderate high-fat (HF) diet would amplify the phenotype focusing on the hypothalamus gene expression profile. Prenatally undernourished rat offspring were HF-fed from weaning until adulthood while body weight and food intake were measured. Tissue weights, glucose tolerance and plasma endocrine parameters levels were determined in 4-month-old rats. Hypothalamic gene expression profiling of adult FR30 rat was performed using Illumina microarray analysis and the RatRef-12 Expression BeadChip that contains 21,792 rat genes. Under HF diet, contrary to C animals, FR30 rats displayed increased body weight. However, most of the endocrine disorders observed in chow diet-fed adult FR30 were alleviated. We also observed very few gene expression changes in hypothalamus of FR30 rat. Amongst factors involved in hypothalamic energy homeostasis programming system, only the POMC and transthyretin mRNA expression levels were preferentially increased under HF diet. Both elevated gene expression levels may be seen as adaptive mechanisms counteracting against deleterious effects of HF feeding in FR30 animals. This study shows that the POMC gene expression is a key target of long-term developmental programming in prenatally undernourished male rat offspring, specifically within an obesogenic environment.
