BACKGROUND: Allergic reactions to food
occurring on commercial airlines have not been
systematically characterized. OBJECTIVE:
We sought to describe the clinical characteristics of allergic reactions
to peanuts on airplanes. METHODS: Participants in the National Registry
of Peanut and Tree Nut Allergy who indicated an allergic reaction while
on a commercial airliner were interviewed by telephone. RESULTS: Sixty-two
of 3704 National Registry of Peanut and Tree Nut Allergy participants indicated
a reaction on an airplane; 42 of 48 patients or parental surrogates contacted
confirmed the reaction began on the airplane (median age of affected subject,
2 years;range, 6 months to 50 years). Of these, 35 reacted to peanuts (4
were uncertain of exposure) and 7 to tree nuts, although 3 of these 7 reacted
to substances that may have also contained peanut. Exposures occurred by
ingestion (20 subjects), skin contact (8 subjects), and inhalation (14
subjects). Reactions
generally occurred within 10 minutes of
exposure (32 of 42 subjects), and reaction severity correlated with exposure
route (ingestion > inhalation > skin). The causal food was generally served
by the airline (37 of 42 subjects). Medications were given in flight to
19 patients (epinephrine to 5) and to an additional 14 at landing/gate
return (including epinephrine to 1 and intravenous medication to 2), totaling
79% treated. Flight crews were notified in 33% of reactions. During inhalation
reactions as a result of peanut allergy, greater than 25 passengers were
estimated to be eating peanuts at the time ofthe reaction. Initial symptoms
generally involved the upper airway, with progression to the skin or further
lower respiratory reactions (no gastrointestinal symptoms). CONCLUSIONS:
Allergic reactions to peanuts and tree nuts caused by accidental ingestion,
skin contact, or inhalation occur during commercial flights, but airline
personnel are usually not notified. Reactions can be severe, requiring
medications, including epinephrine.

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.

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.

BACKGROUND: Allergy to peanuts and tree
nuts (TNs) is one of the leading causes of fatal and near-fatal food-induced
allergic reactions. These allergies can be lifelong and appear to be increasing
in prevalence. Despite the seriousness of these allergies, the prevalence
of peanut and TN allergy in the general population is unknown. OBJECTIVE:
We sought to determine the prevalence of peanut and TN allergy among the
general population of the United States. METHODS: We used a nationwide,
cross-sectional, random digit dial telephone survey with a standardized
questionnaire. RESULTS: A total of 4374 households contacted by telephone
participated (participation rate, 67%), representing 12,032 individuals.
Peanut or TN allergy was self-reported in 164 individuals (1.4%; 95% confidence
interval [CI], 1.2%-1.6%) in 151 households
(3.5%; 95% CI, 2.9%-4.0%). The prevalence of reported allergy in adults
(1.6%) was higher than that found in children under 18 years of age (0.6%).
In 131 individuals, details of the reactions were obtained. When applying
criteria requiring reactions to be typical of IgE-mediated reactions (hives,
angioedema, wheezing, throat tightness, vomiting, and diarrhea) within
an hour of ingestion, 10% of these subjects were excluded. Among the remaining
118 subjects, allergic reactions involved 1 organ system (skin, respiratory,
or gastrointestinal systems) in 50subjects, 2 in 45 subjects, and all 3
in 23 subjects. Forty-five percent of these 118 respondents reported more
than 5 lifetime reactions. Only 53% of these 118 subjects ever saw a physician
for the allergic reaction, and only 7% had self-injectable epinephrine
available at the time of the interview. The prevalence of peanut and TN
allergy was adjusted by assuming that 10% of the remaining 33 subjects
without a description of their reactions would also be excluded and correcting
for a 7% false-positive rate for the survey instrument. A final "corrected"
prevalence estimate of 1.1% (95% CI, 1.0%-1.4%) was obtained. CONCLUSIONS:
Peanut and/or TN allergy affects approximately 1.1% of the general population,
or about 3 million Americans, representing a significant health concern.
Despite the severity of reactions, about half of the subjects never sought
an evaluation by a physician, and only a few had epinephrine available
for emergency use.
-Safe administration of

OBJECTIVES: Specific recommendations
for administering the influenza vaccine to patients with egg allergy are
based on limited scientific data. The objectives of this investigation
were to determine the safety of a 2-dose administration of an influenza
vaccine to patients with egg allergy and to evaluate the usefulness of
skin testing with the influenza vaccine before administration.
STUDY DESIGN: In this multicenter
clinical trial, clinical histories of egg allergy were confirmed by skin
testing with egg and, if possible, by oral challenges with egg. Subjects
with egg allergy received the vaccine in 2 doses, 30 minutes apart; the
first dose was one tenth and the second dose nine tenths of the recommended
dose as determined by age. Subjects without egg allergy were recruited
as control subjects and received 1 age-determined dose of the vaccine.
Skin prick tests with the influenza vaccine were performed on all subjects.
RESULTS: From 1994 to 1997, 83 subjects with egg allergy and 124 control
subjects were evaluated. The content of ovalbumin/ovomucoid was 0.1, 1.2,
and 0.02 micrograms/mL, respectively in the 1994-95, 1995-96, and 1996-97
influenza vaccines. Results of vaccine skin prick tests were positive in
4 subjects with egg allergy and in 1 control subject. All patients with
egg allergy tolerated the vaccination protocol without any significant
allergic reactions.
CONCLUSIONS: These results
demonstrate that patients with egg allergy, even those with significant
allergic reactions after egg ingestion, can safely receive an influenza
vaccine in a 2-dose protocol when the vaccine preparation contains no more
than 1.2 micrograms/mL egg protein.
-Prevalence of self-reported food hypersensitivity among school children in The Netherlands.
Eur J Clin Nutr 1998 Aug;52(8):577-81
Brugman E, Meulmeester JF, Spee-van der Wekke A, Beuker RJ, Radder JJ, Verloove-Vanhorick SP
OBJECTIVES: To provide national
figures on the prevalence of self-reported food hypersensitivity (S-FH),
and the association with socio-demographic variables and some health indicators
in schoolchildren in The Netherlands.
DESIGN: As part of the Child
Health Monitoring System, data were collected from 4450 children, who were
invited for a routine health assessment (response 97%). A questionnaire
on food hypersensitivity was completed by the parents of the children in
primary school and by the children in secondary school themselves. The
measurements on health status were taken by the school physician or nurse
during the school health assessment.
SUBJECTS: Children aged 4-15
y in The Netherlands in three groups in primary school, and in the second
year of secondary school. RESULTS: The prevalence of S-FH was 7.2%. Food
additives and chocolate were most frequently avoided. Of the children with
S-FH, 40% avoided food exclusively either on their own accord or on advice
of relatives. School absence due to illness, use of medication, and medical
treatment were more prevalent in children with S-FH, and their health status
was more often considered moderate or poor by the school physician or nurse.
CONCLUSION: Seven percent
of school-aged children avoid certain types of food or ingredients because
of S-FH. The prevalence of food allergy or food intolerance is probably
lower, since many children with S-FH had not undergone any diagnostic tests.
To prevent unnecessary food restriction, more information for parents is
needed about the possible effects of food restriction on the health of
their children, and they should be encouraged to seek further diagnosis.
-Prevalence of IgE-mediated food allergy among children with atopic dermatitis.
Pediatrics 1998 Mar;101(3 Pt 1):E8
Eigenmann PA, Sicherer SH, Borkowski TA, Cohen BA, Sampson HA
Objective. There is a growing
body of clinical and laboratory evidence to support the notion that food
allergy plays a role in the pathogenesis of atopic dermatitis (AD). However,
the incidence of IgE-mediated food allergy in children with AD is not well
established. Design. A prospective study to determine the prevalence of
IgE-mediated food hypersensitivity among patients referred to a university-based
dermatologist for evaluation of AD. Setting. University hospital pediatric
dermatology clinic. Patients. A total of 63 patients with AD were recruited
(35 male; 32 white, 24 African-American, 7 Asian). Methods. Patients were
assigned an AD symptom score (SCORAD) and were screened for food-specific
serum IgE antibodies to six foods (milk, egg, wheat, soy, peanut, fish)
known to be the most allergenic in children. The levels of food-specific
serum IgE were determined by the CAP System fluoroscein-enzyme immunoassay
(CAP); patients with a value >/=0.7 kIUa/L were invited for an additional
allergy evaluation. Those with CAP values below the cutoff were considered
not food allergic. Patients were considered to be allergic if they met
one of the following criteria for at least one food: 1) reaction on food
challenge; 2) CAP value more than the 95% confidence interval predictive
for a reaction; 3) convincing history of an acute significant (hives, respiratory
symptoms) reaction after the isolated ingestion of a food to which there
was a positive CAP or prick skin test. Results. A total of 63 patients
(median age, 2.8 years; median SCORAD, 41.1) were recruited; 22 had negative
CAP values (without a significant difference in age or SCORAD score, compared
with the 41 with positive specific IgE values). Further allergy
evaluation was offered to
the 41 remaining patients; 10 were lost to follow-up and 31 were evaluated
further. Of these, 19 underwent a total of 50 food challenges (36 double-blind,
placebo-controlled, and 14 open), with 11 patients experiencing 18 positive
challenges (94% with skin reactions). Additionally, 6 patients had a convincing
history with a predictive level of IgE; 5 had a convincing history with
positive, indeterminate levels of IgE; and 1 had predictive levels of IgE
(to egg and peanut) without a history of an acute reaction. Overall, 23/63
(37%; 95% confidence interval, 25% to 50%) had clinically significant IgE-mediated
food hypersensitivity without a significant difference in age or symptom
score between those with or without food allergy.
Conclusions. Approximately
one third of children with refractory, moderate-severe AD have IgE-mediated
clinical reactivity to food proteins. The prevalence of food allergy in
this population is significantly higher than that in the general population,
and an evaluation for food allergy should be considered in these patients.
-Relationship between food-specific IgE concentrations and the risk of positive food challenges in children and adolescents.
J Allergy Clin Immunol 1997 Oct;100(4):444-451
Sampson HA, Ho DG Johns Hopkins University School of Medicine, Baltimore, MD 21287-3923, USA.
BACKGROUND: The double-blind, placebo-controlled food challenge (DBPCFC) is the "gold standard" for diagnosis of food hypersensitivity. Skin prick tests and RASTs are sensitive indicators of food-specific IgE antibodies but poor predictors of clinical reactivity. Previous studies suggested that high concentrations of food-specific IgE antibody were predictive of food-induced clinical symptoms. Because the CAP System FEIA (Pharmacia Diagnostics, Uppsala, Sweden) provides a quantitative assessment of allergen-specific IgE antibody, this study was undertaken to determine the potential utility of the CAP System FEIA in diagnosis of IgE-mediated food hypersensitivity. METHODS: Sera from 196 patients with food allergy were analyzed for specific IgE antibodies to egg, milk, peanut, soy, wheat, and fish by CAP System FEIA. Sera were randomly selected from 300 stored samples of children and adolescents who had been evaluated by history, skin prick tests, and DBPCFCs. The study population was highly atopic; all patients had atopic dermatitis, and approximately 50% had asthma and allergic rhinitis at the time of initial evaluation. The performance characteristics of the CAP System FEIA were compared with those of skin prick tests and the outcome of DBPCFCs or "convincing" histories of anaphylactic reactions. RESULTS: The prevalence of specific food allergies in the study population varied from 22% for wheat to 73% for egg. Allergy to egg, milk, peanut, and soy accounted for 87% of confirmed reactions. The performance characteristics of skin prick tests and CAP System FEIA (egg, milk, peanut, fish) were comparable, with excellent sensitivity and negative predictive accuracy but poor specificity and positive predictive accuracy. The performance characteristics of the CAP System FEIA for soy and wheat were poor. For egg, milk, peanut, and fish allergy, diagnostic levels of IgE, which could predict clinical reactivity in this population with greater than 95% certainty, were identified: egg, 6 kilounits of allergen-specific IgE per liter (kU[A]/L); milk, 32 kU(A)/L; peanut, 15 kU(A)/L; and fish, 20 kU(A)/L. CONCLUSIONS: When compared with the outcome of DBPCFCs, results of CAP System FEIA are generally comparable to those of skin prick tests in predicting symptomatic food hypersensitivity. Furthermore, by measuring the concentrations of food-specific IgE antibodies with the CAP System FEIA, it is possible to identify a subset of patients who are highly likely (>95%) to experience clinical reactions to egg, milk, peanut, or fish. This could eliminate the need to perform DBPCFCs in a significant number of patients suspected of having IgE-mediated food allergy.
- Randomised, double blind, crossover challenge study of allergenicity of peanut oils in subjects allergic to peanuts.

OBJECTIVE: To determine the
in vivo allergenicity of two grades of peanut oil for a large group of
subjects with proved allergy to peanuts. DESIGN: Double blind, crossover
food challenge with crude peanut oil and refined peanut oil. SETTING: Dedicated
clinical investigation unit in a university hospital. SUBJECTS: 60 subjects
allergic to peanuts; allergy was confirmed by challenge tests. OUTCOME
MEASURES: Allergic reaction to the tested peanut oils. RESULTS: None of
the 60 subjects reacted to the refined oil; six (10%) reacted to the crude
oil. Supervised peanut challenge caused considerably less severe reactions
than subjects had reported previously. CONCLUSIONS: Crude peanut oil caused
allergic reactions in 10% of allergic subjects studied and should continue
to be avoided. Refined peanut oil did not pose a risk to any of the subjects.
It would be reasonable to recommend a change in labelling to distinguish
refined from crude peanut oil.

ABSTRACT - The nutritional quality of soybeans (Glycine max) is compromised by a relative deficiency of methionine in the protein fraction of the seeds. To improve the nutritional quality, methionine-rich 2S albumin from the Brazil nut (Betholletia excelsa) has been introduced into transgenic soybeans. Since the Brazil nut is a known allergenic food, we assessed the allergenicity of the 2S albumin. METHODS. The ability of proteins in transgenic and non-transgenic soybeans, Brazil nuts, and purified 2S albumin to bind to IgE in serum from subjects allergic to Brazil nuts was determined by radioallergosorbent tests (4 subjects) and sodium dodecyl sulfate-polyacrylamide-gel electrophoresis (9 subjects) with immunoblotting and autoradiography. Three subjects also underwent skin-prick testing with extracts of soybean, transgenic soybean, and Brazil nut. RESULTS. On radioallergosorbent testing of pooled serum from four subjects allergic to Brazil nuts, protein extracts of transgenic soybean inhibited binding of IgE to Brazil-nut proteins. On immunoblotting, serum IgE from eight of nine subjects bound to purified 2S albumin from the Brazil nut and the transgenic soybean. On skin-prick testing, three subjects had positive reactions to extracts of Brazil nut and transgenic soybean and negative reactions to soybean extract. CONCLUSIONS. The 2S albumin is probably a major Brazil-nut allergen, and the transgenic soybeans analyzed in this study contain this protein. Our study show that an allergen from a food known to be allergenic can be transferred into another food by genetic engineering.
