Food allergy: two common types as seen in breast and formula fed babies.

Cow's milk allergy can develop in both breast and formula fed babies. The allergy developing in breast fed babies is triggered by trace amounts of antigen, tends to cause severe reactions and may persist for several years. The allergy developing in formula fed babies is triggered by large amounts of antigen, is not associated with either positive prick tests or with anaphylactic reactions and often subsides spontaneously.

[Milk feeding of infants in the Turin district. An epidemiological survey].

A cross section study was performed on 1342 children living in the Turin district to examine the modalities followed for milk-feeding during the first year of life. Children examined had been admitted to the infants' ward of the Pediatric University Clinic of Turin suffering from common illness of early infancy. Mothers were asked to fill in a questionnaire concerning breast-feeding, formula feeding and cow's milk feeding. Data collected show that 75% of infants were exclusively breast-fed at birth, that a large number of infants are already fed cow's milk after the 3rd month of life, that hypoallergenic formulas are overused (18.5% among adapted formulas), and that follow-up formulas are underused. Most of the mothers (74%) say that their dietary choices were made by their physician. These data indicate that infant dietary trends in our district are often not in accordance with scientific recommendations.

Cow milk protein allergy during the first year of life: a 12 year experience at the children's hospital, Bangkok.

CMA should be suspected for patients aged less than one year who had persistent diarrhea and/or hematemesis with no enteric pathogen found. Confirmed diagnosis could be made by Goldman challenge test. Patients with confirmed CMA should be treated by changing the cow milk feeding to soy milk feeding. However, in our study, 17% of CMA patients were also allergic to soy protein. Thus the soy milk was replaced by the elemental formula for successful treatment of this group of patients. Beside persistent diarrhea, hematemesis, anemia and hypoalbuminemia were other possible findings among patients with CMA with or without soy protein allergy.

Liquid chromatographic measurement of L-ascorbic acid and D-ascorbic acid in biological samples.

D- and L-Ascorbic acids have been separated using liquid chromatography (LC) on a polymer-coated silica-based NH2 column and the L-isomer has been quantified in human serum, rat serum, rat lung, rat lung perfusate, infant formula (SRM 1846) and mixed food sample (SRM 2383). The D-isomer was observed only in trace amounts in the mixed food sample. The results demonstrate that ascorbic acid was stable on the column and completely recovered from supplemented samples of human serum and that this method of analysis is accurate, precise and has broad application exhibiting no dependence on the nature of the matrices evaluated herein.

Exposure of cadmium from infant formulas and weaning foods.

Cadmium levels were determined in 59 baby food samples, including milk-based, cereal and milk-based and soy-based formulas, recommended from 0 to 18 months of age. Determinations were performed by Zeeman graphite furnace atomic absorption spectrophotometry, after dry ashing, with parallel determinations of certified reference samples. Mean cadmium levels were found to range from 1.10 to 23.5 micrograms/kg fresh weight concentrated formulas. Levels were related to the composition of the diets. Formulas based on cow's milk had the lowest concentrations. Soy formulas contained approximately six times more cadmium than cow's milk formulas, and diets with a cereal content had 4-21 times higher mean levels. The mean weekly intakes of dietary cadmium were estimated to vary between 0.10 and 3.05 micrograms/kg body weight of the child, if the recommended amount of formula were to be consumed at the recommended age, and if the child were of average weight. This estimation however does not include the contribution of cadmium from drinking water. The highest intake on a body weight basis was found in 6-month-old children, consuming the recommended amount of wheat-, oat- and milk-based formulas. This intake is below the provisional tolerable weekly intake (PTWI) of 7 micrograms/kg body weight, established by a WHO/FAO expert group. However, the risk assessment is based on renal effects in adults. Furthermore, preparations of a formula by adding water with cadmium concentrations at the WHO guideline level could lead to intakes at the PTWI level. Compared to breast-fed children, the exposure of dietary cadmium from weaning diets can be up to 12 times higher in children fed infant formula.

Doubling calcium and phosphate concentrations in neonatal parenteral nutrition solutions using monobasic potassium phosphate.

BACKGROUND: Premature infants require high intakes of Ca and P to mimic fetal accretion rates. With the current phosphate salt used, adequate amounts cannot be provided due to the precipitation of Ca and P in TPN solutions. OBJECTIVE: To compare monobasic potassium phosphate (monobasic regimen) and monobasic plus dibasic potassium phosphate (dibasic regimen) on calcium phosphate solubility in 5 amino acid products, and to determine whether solubility differences observed in these products can be explained by buffering capacity. METHODS: TPN solutions were prepared according to standard clinical practice. The following amino acid products were used at 3% concentrations: Primene, Vamin N, TrophAmine, Aminosyn-PF, and Travasol. Dextrose 10%, standard electrolytes, heparin, vitamins and trace elements were added. Calcium (as gluconate) and phosphate (as monobasic or dibasic regimen) were added in one-to-one molar ratios from 0-45 mmol/L. Solutions were inspected macroscopically and microscopically for precipitation under three conditions: immediately, 24 h after preparation at room temperature, and 3 h later in a 37 degrees C water bath. Buffering capacity was determined for each amino acid product by titrating with standardized 0.1 M NaOH. RESULTS: Variations in Ca:P solubility and buffer capacity exist between amino acid solutions. With Primene and Vamin no macroscopic or microscopic precipitation was detected up to 45 mmol/L using monobasic regimen, compared to 25 mmol/L using dibasic regimen with Trophamine. Buffer capacity did not account for the solubility differences observed between the five amino acid products, which were related to the pH of the final solution. CONCLUSIONS: These data will allow clinicians to double the current concentrations of calcium and phosphate in neonatal TPN solutions using monobasic regimen. Although this is particularly relevant to situations when fluid intake is restricted, the effect of the acid load needs to be investigated in extremely low birth weight infants.

Which milk for the preterm infant?

The optimal diet for the low birthweight infant is one that supports a growth rate approximating that of the third trimester of intra-uterine life without imposing stress on the developing metabolic or excretory systems. Although preterm human milk does not meet the energy and nutrient needs of developing preterm infants, the benefits such as contributions to host defence and gastrointestinal trophic aspects, and the psychological benefits of maternal-infant bonding, make it the preferred diet.

Medical foods: products for the management of chronic diseases.

Medical foods are a specific category of therapeutic agents created under the Orphan Drug Act of 1988, which separated medical foods from drugs for regulatory purposes. Products in this category share the requirements that they are intended for the nutritional management of a specific disease, are used under the guidance of a physician, and contain ingredients that are generally recognized as safe (GRAS). An example of medical foods are formulations intended to manage patients with inborn errors in amino acid metabolism. Newer medical foods are designed to manage hyperhomocysteinemia, pancreatic exocrine insufficiency, inflammatory conditions, cancer cachexia, and other diseases.

Regulation of medical foods: toward a rational policy.

Medical foods are enterally administered formulas used as complete or supplemental nutrition support in the treatment of diseases and clinical disorders of hospitalized or incapacitated adult patients. Because clinical trials have failed to demonstrate a consistent benefit of these products on morbidity and mortality rates, it has been difficult to reach consensus on their primary role. Are medical foods components of supportive care or should they be considered pharmacologic treatment? To date, the US Congress has defined medical foods, but the Food and Drug Administration has not developed regulatory statutes for them beyond those designed to ensure the sanitary manufacture of all processed foods. Before effective regulations can be developed, medical foods need to be defined further in order to distinguish them from each other and from other classes of nutritional products such as parenteral nutrients or infant formulas. Because we believe that the role of medical foods is in supportive care rather than pharmacologic therapy, we argue that these products should be subject to regulations similar to those that apply to conventional foods.
