Lower proportion of CD45R0+ cells and deficient interleukin-10 production by formula-fed infants, compared with human-fed, is corrected with supplementation of long-chain polyunsaturated fatty acids.

BACKGROUND: The immune consequences of adding 20:4n-6 and 22:6n-3 fatty acids to preterm infant formula are not known. METHODS: The effect of feeding preterm infants (14-42 days of age) human milk (Human Milk group), infant formula (Formula group), or formula with added long-chain polyunsaturated fatty acids 20:4n-6 and 22:6n-3 (Formula + LCP group) on isolated peripheral blood lymphocytes (by flow cytometry) and lipid composition (by gas-liquid chromatography) was determined. Lymphocytes were stimulated in vitro with phytohemagglutinin to measure soluble interleukin (sIL)-2R and IL-10 production (by enzyme-linked immunosorbent assay). RESULTS: With age, the percentage of CD3+ CD4+ T cells and the percentage of CD20+ cells increased in the Human Milk and Formula + LCP groups (P < 0.05), but not in the unsupplemented Formula group. Compared with the Formula group, CD4+ cells from the Formula + LCP and Human Milk groups expressed more CD45R0 (antigen mature) and less CD45RA (antigen naive) at 42 days of age (P < 0.05). At 42 days, IL-10 production was lower (P < 0.05) in cells of the Formula group than in cells of the Human Milk group. Production of IL-10 by the cells of the Formula + LCP group was not different from that produced by the Human Milk group cells. An age-related decrease (P < 0.05) in sIL-2R production by Formula + LCP lymphocytes was observed, but sIL-2R production at 42 days in the Formula + LCP group did not differ significantly from that in the Human Milk group. Compared with Formula alone, adding LCP to formula resulted in a lower C18:2n-6 and higher C20:4n-6 content in lymphocyte phospholipids (P < 0.05). CONCLUSIONS: Adding LCP to a preterm infant formula resulted in lymphocyte populations, phospholipid composition, cytokine production, and antigen maturity that are more consistent with that in human milk-fed infants. This may affect the ability of the infant to respond to immune challenges.

Severe burns resulting from an exploding teat on a bottle of infant formula milk heated in a microwave oven.

Accidental injury to infants can result from the use of home microwave ovens. The spectrum of injury includes scald burns of the trachea, palate oropharynx and oesophagus due to aspiration and ingestion of foods that have been overheated. There is one previous case report of a child with second-degree burns of 6 per cent of his body area due to explosion of the plastic liner and nipple on a feeding bottle top. We present a case report of an infant who suffered 7 per cent full-thickness burns following explosion of the bottle teat and subsequent splattering with hot milk. He required mid-palmar amputation of his left hand including thumb, index and middle fingers. The full-thickness burns of left cheek and left shoulder were grafted but will result in significant scarring. It is common practice in many homes to heat infant feeds in the microwaves. We suggest that health professionals dealing with children need to be aware of the potential hazards so that appropriate education of parents can take place.

Is drinking water in Abidjan, Côte d'Ivoire, safe for infant formula?

OBJECTIVE: To survey knowledge, attitudes, and practices regarding water use and infant feeding in the Koumassi District of Abidjan, Côte d'Ivoire, and to evaluate the microbiologic quality of source and stored drinking water. DESIGN: Random-cluster household survey. METHODS: We randomly selected 20 clusters, each comprising six households with at least 1 child aged < or =3 years. In each household, we administered a questionnaire and collected source and stored drinking water samples and tested these for chlorine levels and for total coliform and fecal bacteria count ( Escherichia coli ). RESULTS: Municipal water was used for drinking in 112 (93%) of 120 households, and in 99 (83%), it was stored for later use. By 1 month of age, 97 (90%) of 108 infants given drinking water were given stored water for drinking. In 8 (66%) of 12 households where children were receiving artificial feeding, formula was prepared from municipal water without additional treatment. Stored water had lower levels of free chlorine than source water (median of 0.05 versus 0.2 mg/dl; p <.001), and E. coli was detected in 36 (41%) of 87 stored water samples and 1 (1%) of 108 source water samples ( p <.001). CONCLUSIONS: In the Koumassi District of Abidjan, where municipal water is widely available and of good quality, drinking water is stored in most households, is often contaminated with E. coli, and is given to children at a young age. If replacement feeding is to be more widely used to prevent postnatal transmission of HIV-1, communities using stored water need interventions to make stored water safer.

Medium-chain triglycerides in infant formulas and their relation to plasma ketone body concentrations.

A mild ketosis is known to prevail in the mother, fetus, and newborn infant during the 3rd trimester and in the early neonatal period. It has been shown that during an equivalent period in the rat ketone bodies are readily oxidized and serve as key substrates for lipogenesis in brain. Since medium-chain triglycerides are known to be ketogenic, preterm infants may benefit from dietary medium-chain triglycerides beyond the point of enhanced fat absorption. Our objective was to determine the ketogenic response in preterm infants (gestational age: 33 +/- 0.8 wk) fed three different isocaloric formulas by measuring the concentrations of 3-hydroxybutyrate and acetoacetate in the plasma of these infants. At the time of entrance to the study the infants were receiving 110 kcal/kg/24 h. Study I (11 infants): the infants were fed sequentially in the order; PM 60/40 (PM), Special Care Formula (SCF), and Similac 20 (SIM). In SCF greater than 50% of the fat consists of medium-chain length fatty acids while PM and SIM contain about 25%. The concentration of 3-hydroxybutyrate in plasma was significantly higher when infants were fed SCF than PM and SIM [0.14 +/- 0.03, 0.06 +/- 0.01, and 0.05 +/- 0.01 mM, respectively (p less than 0.01)]. Study II (12 infants); the infants were fed SCF, then SIM, or the reverse. The concentration of acetoacetate in plasma was 0.05 +/- 0.01 and 0.03 +/- 0.01 mM when infants were fed SCF and SIM, respectively (0.1 greater than p greater than 0.05). The concentrations of 3-hydroxybutyrate in plasma were similar to those measured in study I for the respective formulas.(ABSTRACT TRUNCATED AT 250 WORDS)
