Cow 's milk allergy/intolerance is treated by complete avoidance of cow 's milk proteins . Because cow 's milk is an important food for infants , its avoidance may lead to an increased risk of growth impairment . Whilst there is evidence for the beneficial effects of extensively hydrolyzed cow 's milk formulate ( eHF ) in infants with cow 's milk allergy/intolerance , little is known about the effects of amino-acid-based formulae ( AA ) in such infants . We therefore performed a prospect i ve , controlled , multi-center trial to study the efficacy of AA in comparison with eHF , on the growth and clinical symptoms of 73 infants ( median age 5.7 months ) with cow 's milk allergy/intolerance and atopic dermatitis . Cow 's milk allergy/intolerance was proven in all infants by double-blind , placebo-controlled food-challenge . We observed a significant improvement in the SCORAD index in both groups , from a mean of 24.6 , at entry , to a mean of 10.7 ( p < 0.0001 ) after 6 months . In the AA group there was a significant increase in the length st and ard deviation score ( p < 0.04 ) , whilst there was no difference in the eHF group . The weight-for-length values were stable in both groups . The energy intake during the study was similar in both groups . Both an AA and eHF result ed in a significant clinical improvement in infants with an early onset of symptoms of cow 's milk allergy/intolerance . Feeding an AA result ed in improved growth compared with feeding eHF , despite similar dietary intakes , and may therefore be considered as a beneficial alternative in infants with severe cow 's milk allergy intolerance OBJECTIVE To determine whether chicken-based formula can replace soy-based formula in infants with cow milk allergy . SUBJECTS AND METHODS Thirty-eight infants with cow 's milk allergy , aged between 2 - 24 months of age were r and omized to receive either chicken-based formula or soy-based formula for 14 days . RESULTS In the group of soy-based formula , 12 out of 18 infants had evidence of intolerance and could not continue with the formula . However , only 4 out of 20 infants in the chicken-based formula group had evidence of clinical intolerance . All other 16 infants were fed the chicken-based formula with success . The number of infants who were intolerant to chicken formula  was significantly lower than the number of those fed soy-based formula ( p = 0.009 ) . CONCLUSION Chicken-based formula can be used more effectively than soy-based formula in infants with cow milk allergy 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 For a minimum of one month ( mean , 54 days ) , 287 infants and children less than 8 years of age were fed an isolated soy-protein formula . Prior to entry into the study , a cow 's milk formula was being fed to 71 % , a soy formula to 9 % , and cow 's milk or other formulas to 20 % . Intolerance to cow 's milk was reported in 35 % of the patients , symptoms indicative of cow 's milk intolerance in 23 % , diarrhea or gastroenteritis in 18 % , a family history of allergy in 13 % , and insufficient weight gain , intolerance to other formulas , or constipation in 11 % . The patients showed normal increases in weight and length during the study . A significant decrease in the following symptoms were reported in the patients from before to after treatment : abdominal cramps , bloating or gas , colic , diarrhea , fussiness , rashes or eczema , spitting up , waking up crying at night , wheezing , and vomiting . It is concluded that , while receiving soy formula , infants and children continued to thrive normally and that the formula was well tolerated . After receiving soy formula , the frequency of undesirable feeding-related symptoms was reduced in the majority of infants and children The purpose of this study was to determine whether a new casein hydrolysate infant formula , Alimentum , could be administered safely to children with cow milk hypersensitivity . The formula was analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and with a sensitive enzyme-linked inhibition immunoassay , and it was judged to be safe for clinical trials in children allergic to cow milk . Twenty-five such children underwent double-blind placebo-controlled oral food challenges with 10 gm of powdered cow milk and casein hydrolysate formula .  All children were highly atopic and had positive skin prick reactions to cow milk . No patient reacted to placebo during a double-blind , placebo-controlled food challenge . Two patients lost their allergy to cow milk and did not react during the challenge ; the remaining patients reacted with a variety of cutaneous , respiratory , and gastrointestinal symptoms within 15 to 90 minutes of challenge . All children tolerated the blinded challenge to the casein hydrolysate and were fed the hydrolysate openly without difficulty . We conclude that this casein hydrolysate is generally safe to feed to children with immediate hypersensitivity to cow milk . We recommend that all infant formulas promoted as " hypoallergenic " be tested in milk-allergic patients to assess their allergenic potential , in addition to st and ard nutritional evaluation and animal testing for antigenicity BACKGROUND Many infants with cow 's milk protein intolerance have adverse reactions to soy , casein and whey hydrolysate formula and to other foods . The recent development of Neocate , a hypoallergenic , nutritionally complete infant formula composed of individual amino acids and other nutrients , has enabled these infants to be stabilized . OBJECTIVE We observed the effect of food challenges in infants with reported hypersensitivity to hypoallergenic formulas . METHODS Eighteen infants ( median age , 7 1/2 months ) were given Neocate formula for 2 months and then underwent a 7-day double-blind placebo-controlled challenge with the formula previously best tolerated . RESULTS In 12 of the 18 infants irritability , vomiting , diarrhea , and /or eczema flares developed during the formula challenge . In two patients symptoms developed immediately , but in the remainder adverse reactions evolved within 7 days ( range , 4 to 7 days ) . Adverse reactions were to soy formula ( six patients ) , whey hydrolysate ( two ) , and casein hydrolysate ( four ) . When infants were 12 months of age , parents reported adverse reactions after the ingestion of other low allergen foods ( median , six ; from a panel of 10 such foods ) . CONCLUSION A group of infants with late-onset adverse reactions to soy , extensively hydrolyzed casein , and whey formulas and to other foods has been identified . Neocate formula proved to be an effective substitute formula for these patients It has been reported that the feeding of cow 's milk may enhance the development of atopy in predisposed infants . A prospect i ve study following children from birth through 15 years of age in a private pediatric practice was design ed to determine if the food ingested during the first months of life is related to the development of atopy in the offspring of allergic families . Each of 328 children with a positive family history of allergy was assigned to one of three groups . according to the feeding preference of the parents : 48 were fed breast milk ; 79 , soy-based formula ; and 201 , cow 's milk formula . All groups had egg , citrus , tomato , and wheat restrictions as well as inhalant allergen avoidance . These were compared to a control group of 580 children with no family history of allergy . Breast fed infants were found to have approximately one-half the incidence of atopy of cow 's milk or soy formula fed infants from atopic families when followed for up to 15 years . Soy feeding produced no advantage over cow 's milk in the prophylaxis of allergic disease . There was a threefold increase in clinical ly apparent atopic disease in offspring of allergic families when compared to controls but only a two-fold increase if the infant was breast fed . These results support the hypothesis that breast feeding and delay of exposure to known allergens may reduce the frequency of clinical allergic disease in the offspring of allergic families Abstract . 1079 of 1548 newborn infants were followed during their first year . 328 were prospect ively contacted once a month . 751 were followed up at child welfare clinics . Altogether 20 were diagnosed as being cow 's milk protein intolerant ( 1.9 % ) . Symptoms from the gastrointestinal tract and the skin predominated . Only 2 had respiratory symptoms . Ten had their symtpoms within one week after the introduction of cow 's milk , 3 of them at their first cow 's milk‐containing meal . A further 4 already had symptoms when fed only human milk . The others ( 6 infants ) showed symptoms after more than one week on a cow 's milk containing diet . Before 2 years of age , 13 had recovered . Twelve of the cow 's milk protein intolerant infants also showed adverse reactions to other foods , soy‐protein intolerance being the most common ( 7 infants ) . A family history of allergy was found in 35 % ( 116 ) of the 328 infants and in 70 % ( 14 ) of those with cow 's milk protein intolerance The allergy preventive effect of extensively ( N ) and partially ( PH ) hydrolysed cows ’ milk formulas compared with a regular formula ( RM ) was assessed in 155 infants with a family history of allergy . No cows ’ milk was given during the first nine months of life and no egg and fish  up to 12 months of age . Breast feeding mothers avoided the same foods . At weaning the infants were r and omised to one of the formula groups . The cumulative incidence of atopic symptoms at 18 months was 51 , 64 , and 84 % in the N , PH , and RM groups , respectively . From 6 to 18 months there were significantly less cumulative atopic symptoms in the N group compared with the RM group , and significantly less than the PH group up to 6 ( N = 25 % ; PH = 46 % ) and 9 months ( N = 34 % , PH = 58 % ) . At 9 months significantly fewer infants in the N group ( 10 % ) than in the PH group ( 33 % ) had a positive skin prick test to eggs . The findings support an allergy preventive effect of an extensively hydrolysed formula , but not of a partially hydrolysed formula , during the first 18 months of life of high risk infants OBJECTIVES We conducted a prospect i ve , r and omized study to evaluate the cumulative incidence of allergy or other adverse reactions to soy formula and to extensively hydrolyzed formula up to the age of 2 years in infants with confirmed cow 's milk allergy . STUDY DESIGN Infants ( n = 170 ) with documented cow 's milk allergy were r and omly assigned to receive either a soy formula or an extensively hydrolyzed formula . If it was suspected that the formula caused symptoms , a double-blind , placebo-controlled challenge ( DBPCFC ) with the formula was performed . The children were followed to the age of 2 years , and soy-specific immunoglobulin E antibodies were measured at the time of diagnosis and at the ages of 1 and 2 years . RESULTS An adverse reaction to the formula was confirmed by challenge in 8 patients ( 10 % ; 95 % confidence interval , 4.4%-18.8 % ) r and omly assigned to soy formula and in 2 patients ( 2.2 % ; 95 % confidence interval , 0.3 % to 7.8 % ) r and omly assigned to extensively hydrolyzed formula .  Adverse reactions to soy were similar in IgE-associated and non-IgE-associated cow 's milk allergy ( 11 % and 9 % , respectively ) . IgE to soy was detected in only 2 infants with an adverse reaction to soy . Adverse reactions to soy formula  were more common in younger ( < 6 months ) than in older ( 6 to 12 months ) infants ( 5 of 20 vs 3 of 60 , respectively , P = .01 ) . CONCLUSIONS Soy formula was well tolerated by most infants with IgE-associated and non-IgE-associated cow 's milk allergy . Development of IgE-associated allergy to soy was rare . Soy formula can be recommended as a first-choice alternative for infants > or=6 months of age with cow 's milk allergy A cohort of 1749 newborns from the municipality of Odense born during 1985 in the University Hospital of Odense were followed prospect ively for the development of cow 's milk allergy (CMA)/cow 's milk protein intolerance ( CMI ) during their first year . The diagnosis of CMA/CMI was based on elimination/open milk challenge procedures according to generally accepted criteria . Thirty nine infants ( 2.2 % ) developed CMA/CMI .  Infants with CMA/CMI were fed cow 's milk formula daily during the first month of life significantly more often than infants in the study population ( p less than .001 ) . All 39 infants with CMA/CMI had ingested cow 's milk formula ( 40 - 830 mL ) neonatally , whereas none of the 210 neonates without supplements of cow 's milk formula  developed CMA/CMI ( p less than .05 ) . Based on a positive skin-prick test ( 2 + or more ) and /or specific serum IgE antibody to cow 's milk ( AL-RAST class 2 or more ) 16 infants were classified as having CMA . In infants solely breast-fed for greater than 1 month CMA was as frequent ( 1 % [ 14/1414 ] as in cow 's milk formula fed infant ( 0.6 % [ 2/335 ] ) . In infants with CMI , a significant majority ( 3.9 % [ 13/335 ] versus 0.7 % [ 10/1414 ] , p less than .001 ) had been cow 's milk formula fed during the first month . These data indicate an association between early cow 's milk formula feeding and development of reproducible adverse reactions to cow 's milk protein . Early neonatal intake of cow 's milk protein is probably a condition of sensitization and later adverse reactions to cow 's milk protein 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 The aim of this study was to compare the allergy-preventive effect of a partially hydrolyzed formula with two extensively hydrolyzed formulas , in infants with a high risk for development of allergic disease . High-risk infants from four Danish centres were included in the period from June 1994 to July 1995 . Five-hundred and ninety-five high-risk infants were identified . High-risk infants were defined as having biparental atopy , or a single atopic first-degree relative combined with cord blood immunoglobulin E ( IgE ) > or = 0.3 kU/l . At birth all infants were r and omized to one of three different blinded formulas .  All mothers had unrestricted diets during pregnancy and lactation and were encouraged to breast-feed exclusively . If breast-feeding was insufficient , one of the three formulas , according to r and omization , was given during the first 4 months . It was recommended not to introduce cow 's milk , cow 's milk products . and solid foods until the age of 4 months . After the age of 4 months a normal unrestricted diet and conventional cow 's milk-based formula were given when needed . All infants were followed-up prospect ively with interview and physical examination at the age of 6 , 12 , and 18 months , and if any possible atopic symptoms were reported . If food allergy was suspected , controlled elimination/challenge procedures were performed in a hospital setting . Of 550 infants included in the study , 514 were seen at all visits and 36 were excluded owing to noncompliance . Of 478 infants who completed the study , 232 were exclusively breast-fed , 79 received an extensively hydrolyzed casein formula ( Nutramigen ) , 82 an extensively hydrolyzed whey formula ( Profylac ) , and 85 a partially hydrolyzed whey formula ( Nan HA ) , during the first 4 months of life . These four groups were identical in regard to atopic predisposition , cord blood IgE , birthplace , and gender . Exclusively breast-fed children were exposed less to tobacco smoke and pets at home and belonged to higher social classes , whereas the three formula groups were identical concerning environmental factors . The frequency of breast-feeding was high ; only eight ( 2 % ) children were not breast-fed at all . The three formula groups were identical in regard to duration of breast-feeding and age at introduction of formula and solid foods . No significant differences were found in the three groups of infants receiving formula milk regarding the cumulative incidence of atopic dermatitis or respiratory symptoms . The cumulative incidence of parental-reported cow 's milk allergy was significantly higher in children fed partially hydrolyzed formula ( Nan HA ) compared with extensively hydrolyzed formula ( Nutramigen or Profylac ) at 12 and 18 months ( NanHA , 7.1 % ; Nutramigen , 2.5 % ; Profylac , 0 % ; p=0.033 ) . The cumulative incidence of confirmed cow 's milk allergy was 1.3 % ( three of 232 ) in exclusively breast-fed infants , 0.6 % ( one of 161 ) in infants fed extensively hydrolyzed formula ( Nutramigen or Profylac ) , and 4.7%(four of 85 ) in infants fed partially hydrolyzed formula ( Nan HA ) . Partially hydrolyzed formula was found to be less effective than extensively hydrolyzed formula in preventing cow 's milk allergy , 0.6 % vs. 4.7 % ( p=0.05 ) , but because of the small number of cases the results should be interpreted with caution . Compared with other similar studies the frequency ofatopic symptoms was low , even though the dietetic intervention did not include either maternal diet during lactation or dietary restrictions to the children after the age of 4 months OBJECTIVE To determine the antigenicity , nutritional adequacy , and growth-promoting efficacy of protein hydrolysate or amino acid-derived formulas in infants with cow milk allergy . STUDY DESIGN Several protein hydrolysate or amino acid-derived formulas were grade d for beta-lactoglobulin content and skin reactivity in 74 atopic children with cow milk allergy proved by a double-blind , placebo-controlled challenge . A r and omized , prospect i ve follow-up study of 9 months included 22 infants with a mean age of 6 months ( 95 % confidence interval , 4 to 7 ) , who were fed an extensively hydrolyzed whey formula ( group We ) , and 23 infants with a mean age of 17 ( 95 % confidence interval , 4 to 7 ) months , who were given an amino acid-derived formula ( group AA ) . RESULTS Both formulas were clinical ly and biochemically tolerated . The mean concentration of essential amino acids in plasma was lower in group We but higher in group AA compared with values for breast-fed control infants ( p = 0.001 ) . There was a different trend between the groups in weight ( p = 0.09 ) and length ( p = 0.006 ) . Growth was promoted in group AA during the follow-up ; it was constant during the first months , followed by a gradual decline in rate in group We . In both groups , atopic eczema improved significantly and progressively , and a downward trend was found in serum total and milk-specific IgE concentrations , proving the efficacy of both formulas . CONCLUSIONS Extensively hydrolyzed formulas are safe and effective for most infants ; an amino acid-derived formula may be preferable for infants with multiple food allergies , especially for the maintenance of normal growth In a prospect i ve study of a 1-year birth cohort of 158 high-risk infants the effect of feeding breastmilk , a casein hydrolysate ( Nutramigen ) or a new ultrafiltrated whey hydrolysate ( Profylac ) on the development of cow milk protein allergy/intolerance ( CMPA/CMPI ) was assessed and compared . All the infants had biparental or severe single atopic predisposition , the latter combined with cord blood IgE > or = 0.5 kU/L. At birth all infants were r and omized to Nutramigen or Profylac , which was used when breastfeeding was insufficient or not possible during the first 6 months of life . During the same period this regimen was combined with avoidance of solid foods and cow milk protein . All mothers had unrestricted diets and were encouraged to do breastfeeding only . Moreover , avoidance of daily exposure to tobacco smoking , furred pets and dust-collecting material s in the bedroom was advised . The infants were followed prospect ively from birth to 18 months of age . All possible atopic symptoms were registered and controlled elimination/challenge studies were performed when symptoms suggested CMPA/CMPI . A total of 154 ( 97 % ) were followed up and 141 followed the diet strictly . Eighty-eight ( 62 % ) of the infants were breastfed for at least 6 months , 20 ( 14 % ) were breastfed exclusively , 59 and 62 had varying amounts of Nutramigen or Profylac respectively . CMPA/CMPI was diagnosed in 1/20 , 1/59 and 3/62 in the breastfed , the Nutramigen and Profylac groups respectively , but 1 of the latter also had Nutramigen . None of the infants showed reactions against  Nutramigen or Profylac . In 4 infants symptoms were provoked by breastmilk when the mother ingested cow milk and in 1 only by cow milk . ( ABSTRACT TRUNCATED AT 250 WORDS Long chain polyunsaturates ( LCP ) status during the early neonatal period is associated with a reduced risk of atopic symptoms and later allergies . In this study , we characterized the immune response of low-risk , term , formula-fed infants r and omized at ≤14 d of age to st and ard term formula ( Formula ) or formula containing LCP ( Formula+LCP ) for 4 wks . Infants exclusively fed human milk  were included for comparison . Peripheral blood was collected at 14 and 42 d of age , and lymphocyte phenotype , proliferation , and cytokine production ( IL-2 , IL-4 , IL-6 , IL-10 , IL-12 , IFN-γ , TNF-α , TGFβ ) were assessed after incubation with β-lactoglobulin ( BLG ) and soy protein ( SOY ) . Lymphocyte proliferation did not differ between groups . Compared with human milk-fed infants at 2 wks , formula-fed infants produced more TNF-α and IFN-γ and had more cells expressing ICAM-1 ( CD54 ) after incubation with BLG and SOY ( p < 0.05 ) . At 6 wks of age , infants fed Formula+LCP  produced more TNF-α with SOY ( 3.2-fold ) and IFN-γ ( 3.3-fold ) with BLG compared with infants fed Formula ( p < 0.05 ) . In conclusion , low-risk term infants fed formula before 14 d of age  produced more TNF-α and IFN-γ in response to food proteins . Feeding Formula+LCP for 4 wks maintained the higher TNF-α and IFN-γ response to these food proteins This study was design ed to assess whether a rice-hydrolysate formula allows normal growth and adequate metabolic balance in infants with cows ' milk protein allergy . Infants ( seven females , nine males ; aged 6–14 months ) were r and omly assigned to receive a rice-hydrolysate formula ( n = 8) or a soy formula ( control group , n = 8) . St and ardized growth indices ( Z scores ) and biochemical parameters were evaluated during a 6-month treatment period . Infants in both groups showed normal growth patterns during the study , and no adverse reactions were seen . Mean plasma biochemical parameters were within the normal ranges , and did not differ between groups . In conclusion , rice-hydrolysate formula may be a nutritionally suitable alternative for infants with cows ' milk protein allergy . Larger studies , with satisfactory power , should be undertaken to confirm these findings Children with cows ' milk protein allergy ( CMPA ) are at risk of insufficient length and weight gain , and the nutritional efficacy of hypo-allergenic formulas should be carefully assessed . In 2008 , a trial assessed the impact of probiotic supplementation of an extensively hydrolysed casein-based formula ( eHCF ) on acquisition of tolerance in 119 infants with CMPA . First analysis of the study results showed that the studied formula allowed improvement of food-related symptoms . The scoring of atopic dermatitis ( SCORAD ) index was assessed at r and omisation and after 6 months of feeding . A post hoc analysis was performed using WHO growth software 's nutritional survey module ( WHO Anthro version 3.2.2 ) . All infants who were fed the study formula tolerated it well . The SCORAD index significantly improved from r and omisation to 6 months of feeding with the study formula . Anthropometric data indicated a significant improvement in the weight-for-age , length-for-age and weight-for-length z scores , as well as in the restoration of normal BMI . The probiotic supplementation did not show any impact on these parameters . The present data showed that this eHCF was clinical ly tolerated and significantly improved the SCORAD index and growth indices BACKGROUND The gastrointestinal microflora is an important constituent of the gut mucosal defense barrier . We have previously shown that a human intestinal floral strain , Lactobacillus GG ( ATCC 53103 ) , promotes local antigen-specific immune responses ( particularly in the IgA class ) , prevents permeability defects , and confers controlled antigen absorption . OBJECTIVE The aim of this study was to evaluate the clinical and immunologic effects of cow 's milk elimination without ( n = 14 ) and with ( n = 13 ) the addition of Lactobacillus GG ( 5 x 10(8 ) colony-forming units/gm formula ) in an extensively hydrolyzed whey formula in infants with atopic eczema and cow 's milk allergy . The second part of the study involved 10 breast-fed infants who had atopic eczema and cow 's milk allergy . In this group Lactobacillus GG was given to nursing mothers . METHODS The severity of atopic eczema was assessed by clinical scoring . The concentrations of fecal alpha 1- antitrypsin , tumor necrosis factor-alpha , and eosinophil cationic protein were determined as markers of intestinal inflammation before and after dietary intervention . RESULTS The clinical score of atopic dermatitis improved significantly during the 1-month study period in infants treated with the extensively hydrolyzed whey formula fortified with Lactobacillus GG . The concentration of alpha 1-antitrypsin decreased significantly in this group ( p = 0.03 ) but not in the group receiving the whey formula without Lactobacillus GG ( p = 0.68 ) . In parallel , the median ( lower quartile to upper quartile ) concentration of fecal tumor necrosis factor-alpha decreased significantly in this group , from 709 pg/gm ( 91 to 1131 pg/gm ) to 34 pg/gm ( 19 to 103 pg/gm ) ( p = 0.003 ) , but not in those receiving the extensively hydrolyzed whey formula only ( p = 0.38 ) . The concentration of fecal eosinophil cationic protein remained unaltered during therapy . CONCLUSION These results suggest that probiotic bacteria may promote endogenous barrier mechanisms in patients with atopic dermatitis and food allergy , and by alleviating intestinal inflammation , may act as a useful tool in the treatment of food allergy This prospect i ve , long-term study assessed the effects of a protein hydrolysate formula on allergy prevention in infants with a family history of allergy . Infants were r and omly assigned to receive either the  hydrolysate formula ( n = 92 ) or an adapted cow milk formula  ( n = 85 ) alone or with breast-feeding for 4 months . The groups did not differ in family allergy history scores or cord blood IgE levels . After 4 months , total IgE levels and allergic reactions did not differ significantly between groups , although the hydrolysate group had a lower prevalence of eczema . At 12 months of age , neither IgE levels nor allergic reactions were significantly different . At 2 years of age , however , 18 allergic reactions had occurred in the hydrolysate group and 31 had occurred in the control group ; the differences were significant for eczema ( p < 0.001 ) but not for asthma . At 4 years of age , allergic signs were found in 11 children in the hydrolysate group and in 17 children in the control group ; the difference was significant only for eczema ( p < 0.01 ) . These results suggest that early feeding of a protein hydrolysate formula to infants at risk for allergies had a long-term preventive effect on the prevalence of eczema but not of asthma Cow 's milk and soy protein allergies are commonly associated with atopic dermatitis ( AD ) in young children .  Amino acid (AA)-based elemental milk formula may improve AD control in these patients . This study investigates the efficacy of AA-based formula in treating young AD patients irrespective of their food allergy status . AD patients younger than 3 yr old were eligible . Sensitization to food allergens was ascertained by skin prick tests and allergen-specific immunoglobulin E ( IgE ) assay . Patients were then r and omly allocated to take either active treatment or pre-existing formulae ( placebo ) for 6 wk . They were allowed a 6-wk washout period before crossed over to the other intervention for another 6 wk . Fifteen AD patients , with median ( interquartile range , IQR ) age of 1.4 ( 0.6 - 2.6 ) yr , were recruited . Their median ( IQR ) SCORAD score was 23.9 ( 10.5 - 29.7 ) . Seven of them were sensitized to cow 's milk or soybean . Among 11 patients who completed the study , the median changes for all scores and urinary eosinophil protein X ( EPX ) concentration were not statistically significant . There was also no evidence of carry-over effects for SCORAD and its various components and global health score , except for urinary EPX concentration ( p = 0.05 ) . Our results do not support the use of AA-based elemental milk formula in treating young children with AD irrespective of their food allergy status Cow 's milk protein allergy ( CMPA ) is best treated by complete elimination of cow 's milk from the diet . For infants with CMPA who can not be breast-fed , formulas based on extensively hydrolyzed proteins or on amino acids are the preferred substitutes for cow 's milk-based formulas . In this study , we compared the tolerance and growth of infants with CMPA who were fed a new extensively hydrolyzed formula containing lactose ( eHF ) with those who were fed an amino acid formula ( AAF ) . This was a prospect i ve , multi-center , r and omized , reference-controlled study . Seventy-seven infants < 12 months old with suspected CMPA were enrolled . In 66 of these , CMPA was confirmed by oral challenge in a double-blind , placebo-controlled food challenge ( DBPCFC ) or by a medical history of severe allergic reaction to cow 's milk and a positive skin prick test . These infants were then tested for their reaction to eHF and AAF in a DBPCFC . All infants tolerated both formulas and were r and omized to receive either eHF ( n = 34 ) or AAF ( n = 32 ) for 180 days . Growth ( weight , length , and head circumference ) and tolerance [ skin , gastro-intestinal , and respiratory tract symptoms of allergy ] were evaluated after 30 , 60 , 90 , and 180 days . There were no significant differences between the two groups in any of the growth measurements . Length and head circumference were similar to Euro-growth st and ards , but weight was slightly lower . Gastro-intestinal and respiratory tract symptoms of allergy were also similar in the two groups . However , whereas SCORAD scores for atopic dermatitis remained constant throughout the study in infants-fed eHF , there was a slight decrease in those fed AAF . Infants-fed eHF had significantly fewer incidents of vomiting than infants-fed AAF and a significantly higher frequency of soft stools . The new eHF is safe and well tolerated in infants diagnosed with CMPA BACKGROUND Cow 's milk allergy ( CMA ) is a common disease of infancy and childhood . An appropriate cow 's milk ( CM ) substitute is necessary for feeding babies with CMA .  CM substitutes are soy formulas and casein- or whey-based extensively hydrolyzed formulas . In several countries , including Italy , goat 's milk ( GM ) formulas are available , and some physicians recommend them for feeding babies with CMA . OBJECTIVE We sought to investigate , in vitro and in vivo , the allergenicity of GM in 26 children with proven IgE-mediated CMA . METHODS All the children underwent skin tests with CM and GM ; detection of specific serum IgE to CM and GM ; and double-blind , placebo-controlled , oral food challenges ( DBPCOFCs ) with fresh CM , GM , and , as placebo , a soy formula ( Isomil , Abbott , Italy ) . CAP inhibition and immunoblotting inhibition assays were also carried out in 1 of 26 and 4 of 26 children with positive RAST results to both CM and GM , respectively . RESULTS All the children had positive skin test responses and CAP results to both CM and GM , all had positive DBPCOFC results to CM , and 24 of 26 had positive DBPCOFCs to GM . In CAP inhibition tests , preincubation of serum with CM or GM strongly inhibited IgE either to CM or to GM . In immunoblotting inhibition assays , preincubation with CM completely extinguished reactivity to GM , whereas GM partially inhibited reactivity to CM . CONCLUSIONS These data strongly indicate that GM is not an appropriate CM substitute for children with IgE-mediated CMA . A warning on the lack of safety of GM for children with CMA should be on the label of GM formulas to prevent severe allergic reactions in babies with CMA ABSTRACT A prospect i ve case‐control study is presented to assess an allergy prevention programme in children up to 36 months of age . Infants born at three maternity hospitals were followed from birth : 279 infants with high atopic risk ( intervention group ) were compared with 80 infants with similar atopic risk but no intervention ( non‐intervention group ) . The intervention programme included dietary measures ( exclusive and prolonged milk feeding diet followed by a hypoantigenic weaning diet ) and environmental measures ( avoidance of parental smoking in the presence of the babies , day care > 2 years of life ) . Mothers in this group who had insufficient breast milk were r and omly assigned to one of two coded formulas : either a hydrolysed milk formula ( Nidina HA , Nestlé ) or a conventional adapted formula ( Nan , Nestlé ) . Other environmental measures remained the same as for the breastfeeding mothers . The non‐intervention group were either breastfed or received the usual Italian milk feeding and weaning diet , without environmental advice . The main outcome measures were anthropometric measurements and allergic disease manifestations . Normal anthropometric data were observed both in the intervention group and in the nonintervention group . The incidence of allergic manifestations was much lower in the intervention group than in the nonintervention group at 1 year ( 11.5 versus 54.4 % , respectively ) and at 2 years ( 14.9 versus 65.6 % ) and 3 years ( 20.6 versus 74.1 % ) . Atopic dermatitis and recurrent wheezing were found in both the intervention group and the non‐intervention group from birth up to the second year of life , while urticaria and gastrointestinal disorders were only present in the non‐intervention group in the first year of life . Conjunctivitis and rhinitis were present after the second year in both the intervention group and the non‐intervention group . Relapse of the same allergic symptom was less in the intervention group ( 13.0 % ) than in the non‐intervention group ( 36.9 % ) . In comparison to the non‐intervention group , there were fewer intervention group cases with two or more different allergic symptoms ( 8.7 versus 32.6 % ) , and they were more likely to avoid steroid treatment ( 0 versus 10.8 % ) and hospital admission ( 0 versus 6.5 % ) . Babies in the non‐intervention group fed with adapted formula were more likely to develop allergies than breastfed babies in the same group . In the intervention group the breastfed infants had the lowest incidence of allergic symptoms , followed by the infants fed the hydrolysed formula ( ns ) . Infants in the intervention group fed the adapted formula had significantly more allergies than the breastfed and hydrolysed milk fed infants , although less than their counterparts in the non‐intervention group . Of the affected subjects in the intervention group , 80.4 % were RAST and /or Prick positive to food or inhalant allergens . Total serum IgE values detected at birth in the intervention group were not predictive , but at 1 and 2 years of age , IgE values more than 2 SD above the mean in asymptomatic babies were found to predictive for later allergy . In breastfed babies the total IgE level at 1 and 2 years of age was lower than in the other two feeding groups . Of the various factors tested in the non‐intervention group , the following were the most important in the pathogenesis of allergic symptoms : ( i ) formula implementation begun in the first week of life ; ( ii ) early weaning ( < 4 months ) ; ( iii ) feeding beef ( < 6 months ) ; ( iv ) early introduction of cow 's milk ( < 6 months ) ; and ( v ) parental smoking in the presence of the babies and early day care admission ( < 2 years of life ) . All the preventive measures used in this study ( exclusive breastfeeding and /or hydrolysed milk feeding , delayed and selective introduction of solid foods , and environmental advice ) were effective at the third year of follow‐up , greatly reducing allergic manifestations in high atopic risk babies in comparison with those not receiving these interventions UNLABELLED B ACKGROUND : Feeding neonates with humanized milk formula in maternity hospitals may increase the prevalence of  milk allergy in infants . However , prospect i ve studies of the possible allergenic effect of very early soy-based formula feeding are lacking . OBJECTIVES To assess the prevalence of soy allergy in infants fed soy-based formula in the first 3 days of life . METHODS The study group included 982 healthy full-term infants born within a 7 month period at a hospital that routinely uses soy-based formula to supplement breastfeeding .  In-hospital feeding was recorded and the parents were interviewed once monthly over the next 6 months regarding feeding practice s and clinical symptoms suggesting soy allergy in the infant . RESULTS Ninety-nine percent of the infants received soy-based formula supplement in hospital , and 33%-42 % at home . No cases of immediate allergic reaction to soy or soy-induced enterocolitis were reported . CONCLUSIONS The use of soy-based formula in the early neonatal period does not apparently increase the prevalence of soy allergy in infants followed for the next 6 months Background / Objectives : To determine the impact of a not hydrolyzed fermented infant formula containing heat-killed Bifidobacterium breve C50 and Streptococcus thermophilus 065 ( HKBBST ) on the incidence of allergy-like events during the first 2 years of life in children at high risk of atopy . Subjects/ Methods : This multicenter , r and omized , double-blind , controlled study included infants at high risk of atopy . Infants used HKBBST or a st and ard infant formula ( SIF ) since birth until 1 year of age , and were followed at 4 , 12 and 24 months after birth .  Skin prick tests ( SPTs ) for six foods and six aeroallergens were systematic ally performed and adverse events ( AEs ) were recorded . In case of potentially allergic AE ( PAAE ) , allergy could be further tested by SPT , patch tests and quantification of specific IgEs . If cow 's milk allergy ( CMA ) was suspected , an oral challenge could also be performed . Results : The study included 129 children , 63 were r and omized to SIF , 66 to HKBBST . The use of HKBBST milk did not alter the proportion of CMA but decreased the proportion of positive SPT to cow 's milk ( 1.7 vs 12.5 % , P=0.03 ) , and the incidence of digestive ( 39 vs 63 % , P=0.01 ) and respiratory potentially allergic AEs ( 7 vs 21 % , P=0.03 ) at 12 months , and that of respiratory PAAEs at 24 months ( 13 vs 35 % , P=0.01 ) . Conclusions : HKBBST decreased the incidence of PAAEs in children with family history of atopy , during the first months of life and after the formula was stopped . Oral tolerance to cow 's milk in infants at high risk of atopy may therefore be improved using not hydrolyzed fermented formulae BACKGROUND The diversity in the perceived prevalence , recovery , and risk factors for cow 's milk allergy ( CMA ) necessitated a large-scale , population -based prospect i ve study . OBJECTIVE We sought to determine the prevalence , cross-reactivity with soy allergy , and risk factors for the development of CMA . METHODS In a prospect i ve study the feeding history of 13,019 infants was obtained by means of telephone interview ( 95.8 % ) or question naire ( 4.2 % ) . Infants with probable adverse reactions to milk were examined , skin prick tested , and challenged orally . RESULTS Ninety-eight percent of the cohort participated in the study . The cumulative incidence for IgE-mediated CMA was 0.5 % ( 66/13,019 patients ) . The mean age of cow 's milk protein ( CMP ) introduction was significantly different ( P < .001 ) between the healthy infants ( 61.6 + /- 92.5 days ) and those with IgE-mediated CMA ( 116.1 + /- 64.9 days ) . Only 0.05 % of the infants who were started on regular CMP formula within the first 14 days versus 1.75 % who were started on formula between the ages of 105 and 194 days had IgE-mediated CMA ( P < .001 ) . The odds ratio was 19.3 ( 95 % CI , 6.0 - 62.1 ) for development of IgE-mediated CMA among infants with exposure to CMP at the age of 15 days or more ( P < .001 ) . Sixty-four patients with IgE-mediated CMA tolerated soy , and none had a proved allergy to soy . CONCLUSIONS IgE-mediated CMA is much less common than generally reported . Early exposure to CMP as a supplement to breast-feeding might promote tolerance . Finally , soy is a reasonable feeding alternative in patients with IgE-mediated CMA The role of cow 's milk in infantile colic in formula-fed infants was estimated in a double-blind study . Sixty colicky infants were given a cow 's milk-containing formula ( Enfamil ) and a cow 's milk-free formula based on soy ( ProSobee ) . Eleven infants ( 18 % ) were free of symptoms while receiving soy formula .  Symptoms of 32 infants ( 53 % ) were unchanged or worse when they were fed cow 's milk formula and soy formula , but symptoms disappeared when they were fed a formula containing hydrolyzed casein ( Nutramigen ) . Symptoms of 17 infants ( 29 % ) could not be related to the diet ; these infants were permitted to continue on a cow 's milk-based formula . A challenge with cow 's milk-based formula after one month ( at approximately age 3 months ) produced symptoms of infantile colic in 22 infants ( 36 % ) . At age 6 months , a challenge with cow 's milk was positive in 11 infants ( 18 % ) with epidermal and gastrointestinal symptoms . Eight infants ( 13 % ) at 12 months of age and five infants ( 8 % ) at 16 months of age were still intolerant to cow 's milk . Cow 's milk seems to be a major cause of infantile colic  in formula-fed infants . A dietary treatment is suggested for moderate or severe forms of the colic . Cow 's milk protein intolerance is common later in infancy in these infants For comparison of the antigenicity and allergenicity of three cow 's milk formulas , serum IgE antibodies to cow 's milk , β‐lactoglobulin and casein , and IgG antibodies to β‐lactoglobulin were analyzed in 94 infants with a family history of allergy . They were participating in a r and omized trial comparing the allergy prophylactic effect of feeding an extensively hydrolyzed ( N ) , a partially hydrolyzed ( PH ) , and a regular cow 's milk formula ( RM ) .  Only infants who had been formula‐fed for 3 months or more were included . IgE antibodies to cow 's milk proteins were more common in the RM group ( 22/34 ) than in the N ( 2/31 ) and PH groups ( 3/29 ) . There was a strong correlation between sensitization to cow 's milk and β‐lactoglobulin ( r=0.85 , P<0.001 ) . The IgG responses to β‐lactoglobulin were low in the N group , intermediate in the PH group , and high in the RM group . High responses , as well as detection of IgE antibodies , were associated with development of atopic disease . The low antigenicity and allergenicity of the extensively hydrolyzed formula support its use in allergy prophylaxis . The partial hydrolysate seemed to be less suitable for this purpose Background and Objective : Feeding long-chain polyunsaturated fatty acids ( LCP ) influences immunity in adults ; however , less is known about their effect during development . The aim of the study was to determine the effect of feeding LCP on immunity in healthy infants during the first 4 months of life . Patients and Methods : Formula-fed infants were r and omized at ≤14 days of age to st and ard term formula ( Formula ) or formula containing LCP ( Formula+LCP ) . Infants exclusively fed human milk ( HM ) were included for comparison . At 16 weeks of age , blood was collected and phenotypes , the ability to proliferate and produce cytokines ( interleukin [IL]-2 , IL-4 , IL-6 , IL-10 , IL-12 , interferon [IFN]-γ , tumor necrosis factor [TNF]-α , TGF-β ) after incubation with phytohemaglutinin ( PHA ) , β-lactoglobulin , or soy protein were measured . Results : Feeding LCP result ed in a higher than and more similar proliferation rate to PHA in HM-fed infants , possibly because of a greater TH1 type cytokine response and a higher percentage of antigen mature ( CD45RO+ ) cells ( P < 0.05 ) . The response to β-lactoglobulin did not differ among groups . After incubation with soy protein Formula+LCP , compared with Formula produced less IL-2 and more TNF-α and had a higher percentage of CD8 + and a lower percentage of CD20 + ( CD20+CD54 + ) cells poststimulation ( P < 0.05 ) . Both formula groups produced less IL-2 after PHA , had a lower percentage of CD80 + cells , and a higher percentage of CD54 + cells after incubation with food proteins ( P < 0.05 ) . Conclusions : Formula-fed infants , at low risk for allergy , respond differently to mitogen and food proteins ex vivo than those fed HM . Feeding LCP altered some of these differences in the direction that is hypothesized to confer immune benefits IgE-mediated cow 's milk allergy ( CMA ) is a heavy burden for patients , particularly for children and their families . Allergen avoidance represents the only therapeutic option , but oral desensitization protocol s have been suggested . Because of the long duration and complexity of these protocol s we examined the feasibility of an oral tolerance induction protocol using a weekly up-dosing schedule . Children with IgE-mediated food allergy to milk , confirmed by a double-blind placebo-controlled food challenge , were recruited . Six of them were r and omized to double-blind desensitization with milk or soy formula as placebo .  Seven patients underwent the protocol in open fashion . The desensitization schedule started with one drop of whole CM diluted 1:25 every week . The dose was doubled weekly until the 18th week to achieve an intake of 200 mL in approximately 4 months . Of the 13 children enrolled , 10 children received CM and 3 control children received soy formula .  Full tolerance ( 200 mL of milk ) was achieved in 7 children ; in 2 children this therapeutic approach failed , because severe reactions occurred during the procedure . One patient achieved a partial tolerance ( 64 mL of milk ) . The three control children receiving placebo still showed a positive food challenge at the end of the study . A weekly up-dosing oral tolerance induction could be a viable alternative to traditional protocol s for children with IgE-mediated CMA BACKGROUND The potential of extensively or partially hydrolyzed formulas to reduce the risks for allergies is controversial . OBJECTIVE We sought to assess the preventive effect of differently hydrolyzed formulas compared with cow 's milk formula ( CMF ) in high-risk infants . METHODS Between 1995 and 1998 , 2252 infants with a hereditary risk for atopy were enrolled in the German Infant Nutritional Intervention Study and r and omly assigned at birth to one of 4 blinded formulas : CMF , partially hydrolyzed whey formula , extensively hydrolyzed whey formula , and extensively hydrolyzed casein formula ( eHF-C ) . The primary end point at 1 year of age was the presence of allergic manifestation , which was defined as atopic dermatitis ( AD ) , gastrointestinal manifestation of food allergy , allergic urticaria , or a combination of these factors . RESULTS At 12 months per protocol , analysis was performed on 945 infants exposed to study formula : 304 ( 13.5 % ) infants had left the study , 138 ( 6.1 % ) infants were excluded because of noncompliance , and 865 infants were exclusively breast-fed the first 4 months of life . The incidence of allergic manifestation was significantly reduced by using eHF-C compared with CMF ( 9 % vs 16 % ; adjusted OR , 0.51 ; 95 % CI , 0.28 - 0.92 ) , and the incidence of AD was significantly reduced by using eHF-C ( OR , 0.42 ; 95 % CI , 0.22 - 0.79 ) and partially hydrolyzed whey formula ( OR , 0.56 ; 95 % CI , 0.32 - 0.99 ) . Family history of AD was a significant risk factor and modified the preventive effect of the hydrolysates . CONCLUSIONS Prevention of allergic diseases in the first year of life is feasible by means of dietary intervention but influenced by family history of AD . The preventive effect of each hydrolyzed formula needs to be clinical ly evaluated In a prospect i ve r and omized study we investigated in 28 mainly bottle-fed infants younger than 60 days whether in acute gastroenteritis a hypoallergenic formula could prevent the development of cow 's milk protein intolerance . Group 1 ( 14 infants ) was fed with a formula adapted to human milk , Group 2 ( 14 infants ) got a semi-elementary formula ( Alfaré ) . After 3 months group II was exposed to cow 's milk protein with a st and ardized challenge and the incidence of CMPI in both groups was calculated . All cases with the acute form of CMPI occurred in group II ( 5/12 ) whereas in group I only one infant suffered from the protracted mild form of the disease . Inspite of the relatively small number of prob and s we conclude from our results that in infants who are not totally breast-fed in the post-enteritic period feeding with a formula adapted to human milk is preferable to hypoallergenic semi-elementary preparations . An allergen free period of 3 months seems to induce symptoms of cow 's milk intolerance , probably as a booster-effect to early sensibilisation OBJECTIVE To assess the preventive effects of different dietary regimens on development of eczema and food allergy in infants at high-risk for allergy . METHODS Forty-six infants whose parents were atopic and umbilical cord IgE > 0.35 kU/L were enrolled in the study . The infants were r and omly assigned at birth to one of 2 dietary regimen protocol s : those in intervention group ( 23 cases ) were breast fed till more than 4 months of age , then followed by feeding with partially hydrolyzed formula ( pHF ) , combined solid foods avoidance until 4-month of age , egg , fish , shrimp avoidance until 12-month of age . The other 23 cases in non-intervention group were breast fed for less than 4 months , or bottle fed with cow 's milk-based formula , egg yolk was introduced at 4-month of age , and egg white at 6-month of age , besides , no any other dietary avoidance was applied . All the infants were followed-up for 18 months . The primary end point was the presence of atopic eczema . Food allergy was detected by fresh food prick-to-prick tests or in vitro sIgE or Fx5E . RESULTS At 6 months , 12 months and 18 months , the incidence of eczema in intervention group was 4.3 % ( 1/23 ) , 8.7 % ( 2/23 ) , and 17.4 % ( 4/23 ) , respectively , which was significantly reduced as compared to that of the non-intervention group , which was 26.1 % ( 6/23 ) , 34.8 % ( 8/23 ) , and 39.1 % ( 9/23 ) , respectively . Food allergy was found in 13.0 % ( 3/23 ) of intervention group and 34.8 % ( 9/23 ) of non-intervention group by skin prick tests or sIgE. Egg white was the most common offending food . CONCLUSION Early life dietary interventions which included breastfeeding , delayed solid food introducing , pHF feeding , and high risk food avoidance could reduce the risk of atopic eczema and food allergy development , and was probably an effective primary intervention method for infants at high risk for atopy Infants ( n = 18 ) with intolerance to extensively hydrolyzed formulas and soy who responded to an L-amino acid-based elemental formula ( AAF ) were studied until 3 years of age . By 2 years of age most tolerated non-formula foods , and by 3 years only 3 required AAF .  Growth normalized during AAF feeding in 4 infants with failure to thrive Background : Exposure to cow ’s milk protein in early infancy could lead to increased rates of allergic diseases later in life . We investigated whether feeding a protein-hydrolyzed formula ( HF ) in the first 6 months of life decreased allergic diseases up to 36 months later . Methods : Newborns who had at least 1 first-degree family member with a history of atopy and could not breast-feed were enrolled . They were fed with HF or cow ’s milk infant formula ( CM ) for at least 6 months via an open-label protocol and were monitored prospect ively at 6 , 18 and 36 months of age to assess allergy sensitization and allergic diseases . Results : A total of 1,002 infants were enrolled and 679 infants were consistently fed the same formula for the first 6 months of life ( 345 HF and 334 CM ) . The percentage of food sensitization ( especially to milk protein ) was significantly lower in the HF group than in the CM group at 36 months ( 12.7 vs. 23.4 % , p = 0.048 ) . There was no significant difference in the prevalence of aeroallergen sensitization between the groups . Occurrence of allergic diseases during the first 3 years of life was significantly correlated with aeroallergen sensitization , but not to food allergen sensitization , parental atopy or feeding types . Conclusions : Infants fed with HF during the first 6 months of life had a significantly lower percentage of sensitization to milk protein allergens , but not allergic diseases during the first 3 years of life . Avoidance of cow ’s milk protein alone in infancy is not enough to decrease rates of allergic diseases Background Infant feeding practice s , particularly the type of milk feeding , have been associated with the development of type 1 diabetes . Aim of the study We studied the relationship between early infant feeding ( during the first year of life ) and diabetes in a large population -based cohort . Methods In 1994–1995 , 6,209 healthy full-term newborns participated in a study examining the effect of supplementary feeding , on development of allergy to cow ’s milk , in maternity hospitals . All supplements in the maternity hospitals were known . Mothers recorded the feeding of infants prospect ively at home . In August 2006 , from a nationwide diabetes registry , 45 children from our cohort were listed as having type 1 diabetes . Results The distribution of cases was similar in the r and omized feeding groups : 9/1,789 in the group that received adapted cow ’s milk-based formula ; 12/1,737 in those who received extensively hydrolyzed formula ; 16/1,859 in those who received banked human milk ; and 8 among those 824 exclusively breast-fed in the hospital . When children who had received cow ’s milk-based formula in the maternity hospital were compared with those without such exposure , less number of children in the former group had diabetes by age 8 ( P = 0.026 ) , but by the end of the follow-up ( 11.5 years ) the difference disappeared ( P = 0.16 ) . Length of breast-feeding and introduction of cereals and other solid foods were similar among those developing type 1 diabetes and those remaining healthy , while early regular daily feeding with cow ’s milk-based formula tended to associate with lower risk for type 1 diabetes ( OR 0.66 ; 95 % confidence interval 0.38–1.13 ; P = 0.08 ) . Conclusions In an extended , secondary analysis of a population -based cohort , very early exposure to cow ’s milk is not a risk factor for type 1 diabetes ; it may in fact diminish its appearance before age 8 BACKGROUND The natural history of allergic disease and its potential for prevention merit close examination because of the explosive worldwide increase in the prevalence and morbidity of atopic disorders . This study examines the development of atopy at age 7 years in 165 children in a high-risk cohort , previously reported from birth to age 4 years . METHODS In this prospect i ve , r and omized , controlled study of food allergen avoidance in infancy , the prophylactic-treated group consisted of infants whose mothers avoided cow 's milk , egg , and peanut during the last trimester of pregnancy and lactation and who , themselves ,  avoided cow 's milk until age 1 year ( casein hydrolysate supplementation before age 1 ) , egg until age 2 years , and peanut and fish until age 3 years . The control group consisted of maternal/infant pairs who followed st and ard feeding practice s. RESULTS Despite a significant reduction in food allergy and milk sensitization before age 2 years , none of the following differed between the groups at age 7 years : food allergy , atopic dermatitis , allergic rhinitis , asthma , any atopic disease , lung function , food or aeroallergen sensitization , serum IgE level , or presence of nasal eosinophils or nasal basophilic cells .  Children with food allergy by 4 years evidence d higher 7-year ( current ) prevalences of allergic rhinitis and asthma ( p < 0.01 ) . Atopic diseases/parameters at age 7 years were shown , by multivariate analysis ( p < 0.05 ) , to be associated with several genetic and environmental risk factors ( male gender , maternal nonwhite ethnicity and asthma , and household smoking ) , as well as predictive atopic markers during infancy ( elevated serum IgE level ; egg , cow 's milk , and peanut sensitization ; and nasal eosinophils and nasal basophilic cells ) . CONCLUSIONS These findings help to : ( 1 ) eluci date the natural history of atopic disease in high-risk children ; ( 2 ) document the progression of allergy from atopic dermatitis , food allergy , and food sensitization to respiratory allergy and aeroallergen sensitization despite food allergy prevention in infancy ; ( 3 ) identify allergy predictive markers ; and ( 4 ) exp and our appreciation of the interactions of genetic and environmental factors in the development of atopy BACKGROUND The isoflavones genistein , daidzein , and their glycosides , found in high concentrations in soybeans and soy-protein foods , may have beneficial effects in the prevention or treatment of many hormone-dependent diseases . Because these bioactive phyto-oestrogens possess a wide range of hormonal and non-hormonal activities , it has been suggested that adverse effects may occur in infants fed soy-based formulas . METHODS To evaluate the extent of infant exposure to phyto-oestrogens from  soy formula  , the isoflavone composition of 25 r and omly selected sample s from five major br and s of commercially available soy-based infant formulas were analysed , and the plasma concentrations of genistein and daidzein , and the intestinally derived metabolite , equol , were compared in 4-month-old infants fed exclusively soy-based infant formula ( n = 7 ) , cow-milk formula ( n = 7 ) , or human breast-milk ( n = 7 ) . FINDINGS All of the soy formulas contained mainly glycosides of genistein and daidzein , and the total isoflavone content was similar among the five formulas analysed and was related to the proportion of soy isolate used in their manufacture . From the concentrations of isoflavones in these formulas ( means 32 - 47 micrograms/mL ) , the typical daily volume of milk consumed , and average bodyweight , a 4-month-old infant fed soy formula would be exposed to 28 - 47 per day , or about 4.5 - 8.0 mg/kg bodyweight per day , of total isoflavones . Mean ( SD ) plasma concentrations of genistein and daidzein in the seven infants fed soy-based formulas were 684 ( 443 ) ng/mL and 295 ( 60 ) ng/mL , respectively , which was significantly greater ( p < 0.05 ) than in the infants fed either cow-milk formulas ( 3.2 [ 0.7 ] and 2.1 [ 0.3 ] ng/mL ) , or human breast-milk ( 2.8 [ 0.7 ] and 1.4 [ 0.1 ] ng/mL ) , and an order of magnitude higher per bodyweight than typical plasma concentrations of adults consuming soy foods . INTERPRETATION The daily exposure of infants to isoflavones in soy infant-formulas is 6 - 11 fold higher on a bodyweight basis than the dose that has hormonal effects in adults consuming soy foods . Circulating concentrations of isoflavones in the seven infants fed soy-based formula were 13000 - 22000 times higher than plasma oestradiol concentrations in early life , and may be sufficient to exert biological effects , whereas the contribution of isoflavones from breast-milk and cow-milk is negligible Purpose To investigate whether specific IgA , IgG , IgG1 and IgG4 responses to cow ’s milk proteins differ between infants with cow ’s milk allergy and infants with cow ’s milk related symptoms ( control subjects ) , and whether early feeding affects these responses as well as specific IgE. Methods A cohort of 6,209 healthy , full-term infants in a double-blind r and omized trial received , as supplementary feeding at maternity hospitals ( mean duration 4 days ) , either cow ’s milk formula , extensively hydrolyzed whey formula or donor breast milk .  Infants who developed cow ’s milk associated symptoms ( n = 223 ) underwent an open oral cow ’s milk challenge ( mean age 7 months ) , which confirmed cow ’s milk allergy in 111 and was negative in 112 . We measured in sera cow ’s milk specific IgE levels with UniCAP ( Phadia , Uppsala , Sweden ) , and β-lactoglobulin and α-casein specific IgA , IgG1 , IgG4 and IgG levels with enzyme-linked immunosorbent assay . Results Infants with IgE-mediated cow ’s milk allergy had lower β-lactoglobulin and α-casein specific IgG1 , IgG4 and IgG levels ( p < 0.05 ) than infants with non-IgE-mediated cow ’s milk allergy or control subjects . Within the group of infants with cow ’s milk allergy , exposure to cow ’s milk during the first few days after birth led to higher β-lactoglobulin and α-casein specific IgG4 levels ( p < 0.005 ) compared to infants fed with either breast milk or extensively hydrolyzed formula . Conclusions Subdued IgG class responses to cow ’s milk proteins characterized IgE-mediated cow ’s milk allergy . In infants who developed cow ’s milk allergy early exposure to cow ’s milk result ed in a heightened specific IgG4 response We prospect ively studied the incidence of atopic disease in healthy term infants with a birth weight between ‐1 and ‐2 SD who were fed a cow milk formula during the first few days of life . A total of 216 infants were r and omized to receive either early feeding with formula before normal breastfeeding was started ( n= 112 ) or “ normal feeding ” with breastmilk ( n= 104 ) . Symptoms of allergy developed in 18%% of the infants before 18 months of age in the formula fed group , as compared to 33 % in the breastfed group ( P < 0.05 ) . The difference was confined to the group of infants with a history of allergy in two family members . Thus , 11 % of the formula‐fed infants developed allergy symptoms , as compared to 61 % of the control infants ( P < 0.01 ) . Our study implies that early feeding during the first days of life with a cow milk formula , before the introduction of breastmilk , may reduce the incidence of allergy symptoms before 18 months of age in infants with a family history of allergy
AUTHORS ' CONCLUSIONS Feeding with a soy formula can not be recommended for prevention of allergy or food intolerance in infants at high risk of allergy or food intolerance .
BACKGROUND Allergies and food reactions in infants and children are common and may be associated with a variety of foods including adapted cow 's milk formula .
Soy based formulas have been used to treat infants with allergy or food intolerance .
However , it is unclear whether they can help prevent allergy and food intolerance in infants without clinical evidence of allergy or food intolerance .
OBJECTIVES To determine the effect of feeding adapted soy formula compared to human milk , cow 's milk formula or a hydrolysed protein formula on preventing allergy or food intolerance in infants without clinical evidence of allergy or food intolerance .
