PURPOSE: Egg (egg white) allergies are among the most common food allergies in infants and young children. Serum egg white-specific IgE (sIgE) levels have been shown to be correlated with clinical symptoms, and the predictive decision point of sIgE levels has been proposed and used widely in the clinical setting. However, some patients whose sIgE levels to egg white are higher than the predictive decision point value show no clinical symptoms, and vice versa. This study was conducted to evaluate the clinical usefulness of sIgE antibodies to egg white and its components in the diagnosis of egg allergies. METHODS: Forty-one patients younger than 2 years of age with no experience of egg intake due to concerns regarding allergies or a non-specific clinical response to eggs were enrolled. Total IgE levels and the levels of IgE antibodies specific for egg white and its components (ovomucoid, ovalbumin, and conalbumin) were measured by ImmunoCAP testing. The clinical response of the subjects was confirmed by an open oral food challenge (OFC). RESULTS: Fifteen (71.4%) out of 21 patients in the egg white-sIgE > or =2 kU/L group showed a positive response, while 10 (50.0%) out of 20 patients in the egg white-sIgE <2 kU/L group showed a negative response to the OFC. There were no statistically significant differences in the levels of sIgE antibodies against egg white and its components between the positive and negative open OFC groups. In addition, there were no statistically significant differences in the levels of sIgE antibodies against egg white and its components based on an intra-group analysis. CONCLUSIONS: Our results show that the sensitivity and specificity of the predictive decision point values for egg white-sIgE antibodies by ImmunoCAP were relatively low in Korean children. In addition, no egg white component predicted the clinical reactivity of the subjects. We suggest that the predictive decision point value for a positive egg oral challenge test by ImmunoCAP should be re-evaluated. Moreover, we suggest that careful personal history recording and challenge tests are necessary for the correct diagnosis of an egg allergy.

BACKGROUND: The role of food allergy in children with atopic dermatitis (AD) has been emphasized. Eggs, cow's milk, soybeans are most common food allergens. We evaluated the serum specific IgE to egg whites (EW), cow's milk (CM), soybeans, and their clinical significance. METHODS: We performed a study with 1, 321 patients (male 739, female 582) who visited Samsung Medical Center during June 1998 and March 2002. We divided them into 9 groups by age. The serum total IgE and specific IgE to EW, CM, and soybeans were measured by Pharmacia AutoCAP system RAST (R) FEIA. RESULTS: The geometric mean of serum total IgE was increased with age (P< 0.05). EW (27.4%) was the most commonly sensitized food allergen in these subjects (P< 0.05), followed by CM (16.1%), and soybeans (8.1%). 37.2% of patients who are younger than 1-year-old showed positive reactions to EW. Reaction rate for this group was higher than others (P< 0.05). The positive reactions to EW were decreased with age (P< 0.05). But, the positive reactions to CM and soybeans did not show any relations to the age. The positive reactions to EW for 4-year-olds and younger were higher than those to CM and soybeans (P< 0.05). 30.7% of patients who had positive reactions to EW, especially 44.3% in age group 1-year-olds and younger (P< 0.05), showed higher specific IgE levels than diagnostic decision points of specific IgE to EW. CONCLUSION: The children with atopic dermatitis, especially young children, have high level of positive responses to egg whites, cow's milk. Sometimes they have serum specific IgE higher than diagnostic decision point. We think that young children with atopic dermatitis are more frequently related to egg and milk allergy.

PURPOSE: The aim of this study was to evaluate the details of the clinical characteristics and food exposure types at the first symptom onset in immediate-type cow's milk allergy (CMA) and egg white allergy (EWA) in Korean children. METHODS: This study included children with immediate-type CMA (n=288) or EWA (n=233) with symptom onset time of 2 hours or less, who visited Samsung Medical Center, Ajou University Hospital, and Soonchunhyang University Seoul Hospital between September 2014 and August 2015. The details of clinical features and food exposure types at the first symptom onset were evaluated by retrospective medical record review using a standardized case report form. RESULTS: The median ages of first symptom onset were 10 months in CMA and 12 months in EWA. The most common types of exposure at the first symptom in CMA were formula milk (29.5%) and milk (29.5%), followed by cheese (17.7%) and yogurt (14.2%). The most common type of exposure in EWA was boiled eggs (35.6%), followed by rice/porridge/soup containing eggs (27.5%), pan-fried eggs (17.6%), and baked goods (9.9%). Cutaneous symptoms were most common in both CMA and EWA, and anaphylaxis was noticed in 36.1% and 30.3%, respectively. Baked goods containing milk or eggs also induced anaphylaxis. The symptom onset time was less than 30 minutes in the majority of patients and the most common place of occurrence was home in both CMA and EWA. CONCLUSION: This study provides comprehensive information on CMA and EWA, and therefore helps clinicians diagnose and guide appropriate food restriction in children with CMA and EWA.

Food allergy is not uncommon among small children. Cow milk and eggs are most frequently incriminated as the major cause of food allergy. A 4-month-old female infant who did not have a previous history of contact with the egg developed anaphylactic shock when an emulsion of raw egg white was rubbed on the buttock by her mother to relieve erosive diaper dermatitis. She had been fed on breast milk. She had no past medical history of any other allergy and no family history of atopy, asthma or allergic rhinitis. Her IgE PRIST was 29.46 IU/ml and multiple antigen simultaneous testing chemiluminescent assay for food specific IgE antibody showed a level 4 positive value only to egg white.

We investigated whether maternal antibodies (mAbs) elicited by dams immunized with recombinant vaccine candidates against avian pathogenic Escherichia coli (APEC) can passively confer protective immunity to chicks. In the present study, pBP244 plasmids carrying selected antigens of APEC were transformed into Salmonella Typhimurium JOL912, which was used as a vaccine candidate against APEC. The hens were immunized with the vaccine candidates using prime or booster doses. The levels of IgG and sIgA specific to the selected antigens increased significantly following prime immunization. To evaluate the persistence of passively transferred mAbs, the levels of IgY and IgA were determined in egg yolks and whites, respectively. The eggs from the immunized group showed consistently increased levels of IgY and IgA until week 16 post-laying (PL) and week 8 PL, respectively, relative to the control group. The presence of mAbs was observed in chicks that hatched from the hens, and titers of plasma IgY were consistently raised in those from the immunized hens by day 14 post-hatching. Further, chicks from the immunized hens were protected from challenge with a virulent APEC strain, whereas those from non-immunized hens showed acute mortality.

Tetrodotoxin is a neurotoxin, so gastrointestinal symptoms are very rare ; these described in the literature are merely nausea and vomiting. Severe complications in the gastrointestinal tract caused by tetrodotoxin have not been radiologically reported. US and CT show thickening of the gastric wall and contraction of the lumen, andupper gastrointestinal series show shortening, lobulation and irregularity of the lesser and greater curevature ofthe body and antrum similar to the findings of corrosive gastritis.
