The impact of early nutrition on incidence of allergic manifestations and common respiratory illnesses in children.

OBJECTIVE To investigate the incidence of allergic and respiratory diseases through age 3 years in children fed docosahexaenoic acid (DHA)- and arachidonic acid (ARA)-supplemented formula during infancy. STUDY DESIGN Children who completed randomized, double-blind studies of DHA/ARA-supplemented (0.32%-0.36%/0.64%-0.72% of total fatty acids, respectively) versus nonsupplemented (control) formulas, fed during the first year of life, were eligible. Blinded study nurses reviewed medical charts for upper respiratory infection (URI), wheezing, asthma, bronchiolitis, bronchitis, allergic rhinitis, allergic conjunctivitis, otitis media, sinusitis, atopic dermatitis (AD), and urticaria. RESULTS From the 2 original cohorts, 89/179 children participated; 38/89 were fed DHA/ARA formula. The DHA/ARA group had significantly lower odds for developing URI (odds ratio [OR], 0.22; 95% confidence interval [CI], 0.08-0.58), wheezing/asthma (OR, 0.32; 95% CI, 0.11-0.97), wheezing/asthma/AD (OR, 0.25; 95% CI, 0.09-0.67), or any allergy (OR, 0.28; 95% CI, 0.10-0.72). The control group had significantly shorter time to first diagnosis of URI (P = .006), wheezing/asthma (P = .03), or any allergy (P = .006). CONCLUSIONS DHA/ARA supplementation was associated with delayed onset and reduced incidence of URIs and common allergic diseases up to 3 years of age.

Growth and Tolerance of Healthy Term Infants Receiving Hydrolyzed Infant Formulas Supplemented With Lactobacillus rhamnosus GG: Randomized, Double-Blind, Controlled Trial

Healthy, term infants received extensively hydrolyzed casein formula (EHF; control), the same formula supplemented with Lactobacillus rhamnosus GG (EHF-LGG), or partially hydrolyzed whey:casein (60:40) formula supplemented with LGG (PHF-LGG), in this double-blind, randomized, controlled, parallel, prospective study. Anthropometric measures and 24-hour dietary and tolerance recalls were obtained at 30, 60, 90, 120, and 150 days of age. Blood collected in a subset of infants was analyzed for fatty acid profiles in plasma and red blood cells and for markers of allergic sensitization. Adverse events were recorded throughout the study. Growth rates were not statistically different between EHF and PHF-LGG and between EHF and EHF-LGG from day 14 to day 30, 120, or 150. No relevant differences in formula tolerance, adverse events, or allergic and immune markers were demonstrated between groups. The extensively and partially hydrolyzed formulas supplemented with LGG support normal growth in healthy, term infants and are well tolerated and safe.

Clinical Response to 2 Commonly Used Switch Formulas Occurs Within 1 Day

Very fussy or extremely fussy infants were randomized to receive: soy-based formula (Soy: n = 82) or a partially hydrolyzed cows milk protein (CMP), low-lactose formula (PHF: n = 77) in a multicenter, double-blind, randomized, parallel, prospective 28-day feeding trial. Body weight and infant formula tolerance were reported. Adverse events were recorded throughout the study. A significant reduction in mean scores of fussiness, gas, spit-up, and crying compared with baseline measures was observed in infants who received either Soy or PHF within 1 day of formula intake; improvement in symptoms was sustained by study end. Stool consistency remained constant through day 28 in the PHF group, whereas stools in the Soy group became more firm by day 2 and did not return to prestudy consistency. PHF, with a protein profile patterned more closely on human breast milk, improved symptoms of formula intolerance as well as soy-based formula.
