Selenium supplementation in pediatric patients using parenteral nutrition: Is it time to do something?

OBJECTIVE To analyze the nutritional status of selenium and verify the effect of its supplementation in pediatric patients during 14 days of parenteral nutrition (PN). METHOD This is a series of cases with patients followed for two weeks while using PN. Data collection was performed at the beginning (T0), in the 7th (T1) and 14th days of PN (T2). The supplemented group received 2 µg/kg/day of selenous acid. Weight and height were measured for nutritional status assessment. Tests requested: plasma selenium, albumin, pre-albumin, C-reactive protein (CRP), total cholesterol and HDL-cholesterol. RESULTS Fourteen (14) patients with inflammatory process and with low or very low weight for their ages were evaluated. In both groups (with and without supplementation), all patients had low selenium levels. Median plasma selenium concentrations were 17.4 µg/L (T0), 23.0 µg/L (T1) and 20.7 µg/L (T2). Increase and reduction of selenium occurred both in patients with high CRP and in those presenting normalization of this parameter. CONCLUSION Lower plasma selenium levels have been detected since the start of the research and supplementation (2 µg/kg/day of selenous acid) was not to enough to approach the reference values.

ARTIGO ORIGINALDeve‐se individualizar a nutrição parenteral pediátrica?1Should pediatric parenteral nutrition be individualized?

INTRODUCTION: Parenteral nutrition (PN) formulations are commonly individualized, since their standardization appears inadequate for the pediatric population. This study aimed to evaluate the nutritional state and the reasons for PN individualization in pediatric patients using PN, hospitalized in a tertiary hospital in Campinas, São Paulo. METHODS: This longitudinal study comprised patients using PN followed by up to 67 days. Nutritional status was classified according to the criteria established by the World Health Organization (WHO) (2006) and WHO (2007). The levels of the following elements in blood were analyzed: sodium, potassium, ionized calcium, chloride, magnesium, inorganic phosphorus, and triglycerides (TGL). Among the criteria for individualization, the following were considered undeniable: significant reduction in blood levels of potassium (<3mEq/L), sodium (<125mEq/L), magnesium (<1mEq/L), phosphorus (<1.5mEq/L), ionic calcium (<1mmol), and chloride (<90mEq/L), or any value above the references. RESULTS: Twelve pediatric patients aged 1 month to 15 years were studied (49 individualizations). Most patients were classified as malnourished. It was observed that 74/254 (29.2%) of examinations demanded individualized PN for indubitable reasons. CONCLUSION: The nutritional state of patients was considered critical in most cases. Thus, the individualization performed in the beginning of PN for energy protein adequacy was indispensable. In addition, the individualized PN was indispensable in at least 29.2% of PN for correction of alterations found in biochemical parameters.
