    Input: AIMS Different protein sources could determine differences in the maturation of the exocrine pancreas in humans during the first months after birth ; however , no studies have been carried out in man to evaluate the effect of a hydrolyzed protein diet on exopancreatic function . Our aim was therefore to determine the effect of two different milk formulas on pancreatic secretion in patients with cow 's milk protein allergy ( CMPA ) . METHODS We selected 12 infants ( median age , 3.0 months ) , fed for 6 weeks with a hydrolyzed casein-based formula , and 14 infants ( median age , 3.0 months ) who received a soy-protein based formula over the same period . As controls , two groups of age-matched infants with no gastrointestinal disease and receiving a free diet  were studied . In the patients with CMPA a secretin-cerulein test was performed at the commencement of the diet and after 6 weeks ; in the controls the same test was performed only once . Enzyme concentrations and outputs of trypsin , chymotrypsin , lipase , and phospholipase were assayed . RESULTS No significant difference was observed between the two groups of patients with CMPA for any of the enzymes studied , either at base line or after 6 weeks of diet . No difference was recorded between CMPA patients and age-matched controls on a free diet either . In both CMPA groups there was a significant increase over basal values in trypsin , chymotrypsin , and lipase concentrations after 6 weeks . Furthermore , there was a significant positive correlation between the age of the patients and enzyme concentrations . Mean daily weight gain was 27.4 + /- 3.9 g with hydrolyzed casein and 27.2 + /- 3.5 g in soyfed patients . CONCLUSIONS It is suggested that the diets with different protein content used in subjects with CMPA did not determine any difference in the stimulation of proteolytic and lipolytic pancreatic enzymes Background Immunologic development of soy-fed infants has not been extensively studied . Early studies of soy flour – based formulas showed decreased immunoglobulin production when soy protein intake was limited . However , there were no significant differences in rotavirus vaccine responses between breast-fed and soy protein isolate – based formula-fed infants .  Nucleotides added to milk-based formula benefit infant immune status , but reports of the immunologic effects of adding nucleotides to soy-based formula are not available . This study evaluated immune status and morbidity of infants fed soy protein isolate formulas with and without added nucleotides for 1 year . Methods Newborn , term infants enrolled in a masked 12-month feeding trial were assigned r and omly to groups fed soy formula with or without added nucleotides ( n = 94 , n = 92 ) . A nonr and omized human milk/formula cohort ( n = 81 ) was concurrently enrolled . Recommended immunizations were administered at 2 , 4 , and 6 months . Immune status was determined from antibody responses to Haemophilus influenzae type b , tetanus , diphtheria , and poliovirus vaccines at 6 , 7 , and 12 months . Parents and physicians reported morbidity data . Results All vaccine responses were within normal ranges . No response differences were observed between infants fed soy formula and those fed nucleotide-supplemented soy . However , antibody to H. influenzae type b at 7 and 12 months was higher in infants fed nucleotide-supplemented soy than in infants fed human milk/formula ( P = 0.007 , P = 0.008 , respectively ) . Human milk/formula-fed infants had higher poliovirus neutralizing antibody at 12 months than did soy-fed infants ( P = 0.016 ) . Morbidity analyses showed that only physician-reported diarrhea was different among groups ( groups fed human milk/formula had less diarrhea than did soy groups , P = 0.011 ) . Conclusions Term infants fed soy protein isolate – based formulas  have normal immune development as measured by antibody responses to childhood immunizations Abstract Objectives : To investigate the association between the duration of exclusive breast feeding and the development of  asthma related outcomes in children at age 6 years . Design : Prospect i ve cohort study . Setting : Western Australia . Subjects : 2187 children ascertained through antenatal clinics at the major tertiary obstetric hospital in Perth and followed to age 6 years . Main outcome measures : Unconditional logistic regression to model the association between duration of exclusive breast feeding and outcomes related to asthma or atopy at 6 years of age , allowing for several important confounders : sex , gestational age , smoking in the household , and early childcare . Results : After adjustment for confounders , the introduction of milk other than breast milk before 4 months of age was a significant risk factor for all asthma and atopy related outcomes in children aged 6 years : asthma diagnosed by a doctor ( odds ratio 1.25 , 95 % confidence interval 1.02 to 1.52 ) ; wheeze three or more times since 1 year of age ( 1.41 , 1.14 to 1.76 ) ; wheeze in the past year ( 1.31 , 1.05 to 1.64 ) ; sleep disturbance due to wheeze within the past year ( 1.42 , 1.07 to 1.89 ) ; age when doctor diagnosed asthma ( hazard ratio 1.22 , 1.03 to 1.43 ) ; age at first wheeze ( 1.36 , 1.17 to 1.59 ) ; and positive skin prick test reaction to at least one common aeroallergen ( 1.30 , 1.04 to 1.61 ) . Conclusion : A significant reduction in the risk of childhood asthma at age 6 years occurs if exclusive breast feeding is continued for at least the 4 months after birth . These findings are important for our underst and ing of the cause of childhood asthma and suggest that public health interventions to optimise breast feeding may help to reduce the community burden of childhood asthma and its associated traits . Key messages Asthma is the leading cause of admission to hospital in Australian children and its prevalence is increasing Whether breast feeding protects against asthma or atopy , or both , is controversial Asthma is a complex disease , and the relative risks between breast feeding and asthma or atopy are unlikely to be large ; this suggests the need for investigation in a large prospect i ve birth cohort with timely assessment of atopic outcomes and all relevant exposures Exclusive breast feeding for at least 4 months is associated with a significant reduction in the risk of asthma and atopy at age 6 years and with a significant delay in the age at onset of wheezing and asthma being diagnosed by a doctor Public health interventions to promote an increased duration of exclusive breast feeding may help to reduce the morbidity and prevalence of childhood asthma  and OBJECTIVES To determine the prevalence of soy allergy in IgE-associated cow 's milk allergy ( CMA ) . STUDY DESIGN Children < 3.5 years with documented IgE-associated CMA ( n = 93 ) were evaluated for soy allergy by double-blind , placebo-controlled food challenge , open challenge , or convincing previous history of an anaphylactic reaction to soy .  Children tolerant to soy at entry received soy formula and were followed up for 1 year . RESULTS Of this IgE-associated CMA cohort ( ages 3 to 41 months ) , 14 % ( 95 % CI = 7 . 7%-22.7 % ) were determined to have soy allergy , 12 definitely at entry and 1 possibly after 1 year of soy ingestion . The latter child experienced severe failure to thrive at enrollment and exhibited improved growth while receiving soy during follow-up but was diagnosed with eosinophilic esophagitis at study completion . Improved growth ( P < .05 ) occurred in the non-soy-allergic cohort ingesting soy formula ( 579 31 mL/d ) during the year of follow-up . CONCLUSIONS Soy allergy occurs in only a small minority of young children with IgE-associated CMA . As such , soy formula may provide a safe and growth-promoting alternative for the majority of children with IgE-associated CMA shown to be soy tolerant at the time of introduction of soy formula A recent increase in the prevalence of atopic disorders and the enormous costs of management of atopic patients have prompted attempts at prevention . We have examined the effect of exclusive breast feeding and of feeding different infant formulas on incidence of atopic disease in a prospect i ve r and omized controlled study . Seventy-two infants were recruited into each of the following groups : cow milk whey hydrolysate formula ( NAN/HA ) conventional cow milk formula ( Similac ) , soy-based formula ( Isomil ) , and exclusive breast feeding for greater than 4 months .  The cumulative incidence of atopic eczema , recurrent wheezing , rhinitis , gastrointestinal symptoms , and colic were noted . Skin prick tests and radioallergosorbent tests for IgE antibodies to milk and soy were performed . At 12 and 18 months of age , the incidence of atopic eczema as also that of all atopic symptoms was significantly lower and similar in the breast-fed and whey hydrolysate groups , compared with the cow milk and soy formula groups . IgE antibodies were detected more often in the cow milk and soy formula groups , especially the former . Among symptomatic infants , fewer skin positive prick tests were seen in the soy group compared with the cow milk group . Our observations show that among infants at high risk of developing atopic disease because of positive family history , exclusive breast feeding or whey hydrolysate formula is associated with a lower incidence and thus a delay in the occurrence of allergic disorders compared with groups fed conventional cow milk or soy formulas BACKGROUND Allergy is a common cause of illness . The effect of feeding different infant formulas on the incidence of atopic disease and food allergy was assessed in a prospect i ve r and omized double-blind study of high-risk infants with a family history of atopy . METHODS 216 high-risk infants whose mothers had elected not to breast-feed were r and omized to receive exclusively a partial whey hydrolysate formula or a conventional cow 's milk formula or a soy formula until 6 months of age . Seventy-two high risk infants breast-fed for > or = 4 months were also studied . RESULTS Follow-up until 5 years of age showed a significant lowering in the cumulative incidence of atopic disease in the breast-fed ( odds ratio 0.422 [ 0.200 - 0.891 ] ) and the whey hydrolysate ( odds ratio 0.322 [ 0.159 - 0.653 ) groups , compared with the conventional cow 's milk group . Soy formula was not effective ( odds ratio 0.759 [ 0.384 - 1.501 ] ) . The occurrence of both eczema and asthma was lowest in the breast-fed and whey hydrolysate groups and was comparable in the cow 's milk and soy groups . Similar significant differences were noted in the 18 - 60 month period prevalence of eczema and asthma . Eczema was less severe in the whey hydrolysate group compared with the other groups . Double-blind placebo-controlled food challenges showed a lower prevalence of food allergy in the whey hydrolysate group compared with the other formula groups . CONCLUSIONS Exclusive breast-feeding or feeding with a partial whey hydrolysate formula is associated with lower incidence of atopic disease and food allergy . This is a cost-effective approach to the prevention of allergic disease in children The determinants of wheezing and allergy were investigated in 453 children with a family history of allergic disease . A r and omised controlled trial examined the effects of withholding cows ' milk protein during the first three months of life and replacing cows ' milk with soya milk . The children were followed up to the age of 7 years . Withholding cows ' milk did not reduce the incidence of allergy or wheezing . Children who had ever been breast fed had a lower incidence of wheeze than those who had not ( 59 % and 74 % respectively ) . The effect persisted to age 7 years in the non-atopics only , the risk of wheeze being halved in the breast fed children after allowing for employment status , sex passive smoking , and overcrowding . Allergic disease was not associated with exposure to tobacco smoke , house dust mite antigen , or cats . Breast feeding may confer long term protection against respiratory infection Forty‐eight children with a biparental history of atopic disease were followed from birth to 4 years of age . One group was fed soy and the other cow 's milk from weaning to 9 months of age . Two‐thirds of the children developed symptoms of atopic disease with no significant difference between the groups . No difference was found in the serum immunoglobulins ( IgE antibodies , IgA , IgG and IgM ) during the observation period . The soy fed children showed transiently lower levels of IgG antibodies to cow 's milk but higher levels of IgG antibodies to soy protein . Six children showed cow 's milk intolerance and a further five had symptoms possibly related to the use of cow 's milk . Withholding cow 's milk during the first 9 months did not reduce the incidence of symptoms of cow 's milk intolerance from birth to 4 years of age . Thus , no benefit was found from replacing cows ' milk with soy . A prolonged breast feeding seems most rational for infants at risk of developing atopic disease , even if the present study did not show evidence of a prophylactic effect of breast milk
