Specific IgE to gliadin was proposed as a marker for wheat dependent exercise induced anaphylaxis, while Tri a 14 was found to induce IgE response in baker's asthma. We evaluated whether these components could be used for discriminating phenotypes of wheat allergy. Twenty-nine patients who were wheat-induced anaphylaxis and/or urticaria (n=21, group I) and baker's asthma (n=8, group II) were enrolled. The prevalence of serum specific IgE to Tri a 14 was higher in group II (25%) than in group I (4.8%), while the serum specific IgE to gliadin was significantly higher in group I (70%) than in group II (12.5%). The cutoff value for predicting the baker's asthma using the ratio of serum specific IgE to Tri a 14 to gliadin was 742.8 optical densityx1,000/(kU/L) with high sensitivity and specificity. These findings suggest that Tri a 14/gliadin may be a potential marker for predicting baker's asthma.

This is the first reported detection of serum IgE antibody to piperacillin-human serum albumin (HSA) conjugate in a patient presenting with anaphylaxis that developed after occupational exposure. A 24-yr-old nurse, who had worked at a University Hospital for 2 yr, experienced chest tightness, dizziness, generalized urticaria, abdominal pain, and diarrhea 10 min after administering a piperacillin injection. She had previously suffered from atopic dermatitis. A skin prick test for common inhalant allergens was entirely negative; in contrast, her serum total IgE was elevated (283 IU/mL). A high level of piperacillin-specific serum IgE was detected by ELISA using piperacillin-HSA conjugate. Significant inhibition upon addition of both free piperacillin and piperacillin-HSA conjugate was detected by inhibition ELISA. These data suggest that piperacillin exposure in the workplace can induce occupational anaphylaxis and urticaria mediated by an interaction of IgE with the hapten of piperacillin.

OBJECTIVETo determine the relation between the change of immunology indexes of serum and the occurrence of anaphylaxis in patients induced by Qingkailing injection, and to establish the method of detection of the type of anaphylaxis in patients induced by traditional Chinese medicine (TCM) injection.

METHODIn a prospective nested case-control study, we compared the concentration of IgE, IgG, IL-2, IL-4 of 20 cases in anaphylaxis induced by Qingkailing injection with those from 60 matched controls who remained normal after the using Qingkailing injection. The correlation between the change of IgE, IgG, IL-2, IL-4 of serum and the occurrence of anaphylaxis in patients induced by Qingkailing injection was determined, and we also evaluate the clinical values of IgE, IgG, IL-2, IL-4 of serum in diagnosis of anaphylaxis in patients induced by Qingkailing injection by Binary-Logistic regression analysis.

RESULTThe concentrations of IgE, IgG, IL-2, IL-4 of serum of 20 cases were significantly higher than those in controls (P < or = 0. 05). The concentrations of IgE, IgG, IL-2, IL4 of serum of 20 cases after the treatment with Qingkailing injection were significantly higher than those before the treatment with Qingkailing injection (P < or = 0.05). The Exp(B) of IgE, IgG, IL-2, IL-4 were 22. 018 (95.0% CI for EXP was 3.268-310.831), 11.271 (95.0% CI for EXP was 1.91-3.024), 23.612 (95.0% CI for EXP was 3.012-421.187), 16.486 (95.0% CI for EXP was 1.233-205.413), respectively.

CONCLUSIONThe allergic reaction caused by Qingkailing injection may be due to type I allergic reactions; The presence of IgE, IgG, IL-2, IL-4 can serve as clinical evaluation indicators in evaluation the damage degree of immune system caused by anaphylaxis in patients induced by Qingkailing injection. Cytokines are more likely to become the effective evaluation index in diagnosis of anaphylaxis in patients induced by TCM injection.

OBJECTIVETo investigate allergic reactions of traditional Chinese medicine (TCM) injections, and to determine the contents of serum IgE and histamine in sensitized animal. The correlation between the preceding contents in serum and allergic reactions may be found, thus offering experimental evidences for advancing the accuracy of anticipation by type I allergy.

METHODWe carried out passive cutaneous anaphylaxis (PCA) tests,active systemic anaphylaxis (ASA) tests and anaphylactoid reactions using three TCM injections, and determined the contents of serum OVA-sIgE, total serum IgE and histamine in sensitized animals by ELISA method.

RESULTThe results of PCA test were negative, and there was no significant difference for total serum IgE level between experimental group and normal saline group. In the study of adjuvant effect in TCM injections + OVA (at the dose level that doesn't cause allergic reactions), the PCA results of SHL and YXC were positive and there was a increase in content of serum OVA-sIgE, while the PCA result of QKL was negative with a unobvious increase in the content of serum OVA-sIgE. The content of total serum IgE wasn't remarkably increased in each group and the results of ASA test were all positive. Three injections all caused anaphylactoid symptoms in guinea pigs in different doses or injection speed and the response intensity was found to be dosage and injection speed dependant. Furthermore, there was no significant difference for the content of total serum IgE in each group, whereas serum histamine concentration in every experimental group was markedly higher than normal saline group.

CONCLUSIONSHL and YXC increase the sensitivity of guinea pigs on OVA, and three TCM injections can cause allergic reactions in guinea pig. Allergic reactions of three TCM injections are correlated with specific IgE antibodies and histamine contents.

OBJECTIVE: To increase the death rate of fatal anaphylaxis in guinea pigs and the detectahie level of the tryptase of mast cell in hlood serum. METHODS: Seventy-four guinea pigs were randomly divided into five groups: original model group, original model control group, improved model group, improved model control group, improved model with non-anaphylaxis group. Using mixed human serum as the allergen, the way of injection, sensitization and induction were improved. ELISA was used to detect the serum mast cell tryptase and total IgE in guinea pigs of each group. RESULTS: The death rate of fatal anaphylaxis in original model group was 54.2% with the different degree of hemopericardium. The severe pericardial tamponade appeared in 9 guinea pigs in original model group and original model control group. The death rate of fatal anaphylaxis in improved model group was 75% without pericardial tamponade. The concentration of the serum total IgE showed no statistically difference hetween original model group and original model control group (P > 0.05), hut the serum mast cell tryptase level was higher in the original model group than that in the original model control group (P > 0.05). The concentration of the serum total IgE and the serum mast cell tryptase level were significantly higher in improved model group than that in the improved model control group (P < 0.05). CONCLUSION The death rate of the improved model significantly increases, which can provide effective animal model for the study of serum total IgE and mast cell tryptase.

Anisakidae larvae can cause anisakiasis when ingested by humans. Although several groups have reported a gastrointestinal Anisakis allergy among people in Spain and Japan, our report is the first to summarize the clinical features of 10 Anisakis allergy cases in Korea. We enrolled 10 Korean patients (6 men and 4 women) who complained of aggravated allergic symptoms after ingesting raw fish or seafood. Sensitization to Anisakis was confirmed by detecting serum specific IgE to Anisakis simplex. The most common manifestation of anisakiasis was urticaria (100%), followed by abdominal pain (30%) and anaphylaxis (30%). All patients presenting with these symptoms also exhibited high serum specific IgE (0.45 to 100 kU/L) to A. simplex. Nine patients (90%) exhibited atopy and increased total serum IgE levels. The fish species suspected of carrying the Anisakis parasite were flatfish (40%), congers (40%), squid (30%), whelk (10%), and tuna (10%). Anisakis simplex should be considered as a possible causative food allergen in adult patients presenting with urticaria, angioedema, and anaphylaxis following the consumption of raw fish or seafood.

Wheat dependent exercise-induced anaphylaxis (WDEIA) is a rare but potentially severe food allergy caused by the combination of wheat ingestion and physical exercise. The impact of WDEIA on quality of life (QOL) is unclear. This study characterized the clinical and laboratory features and investigated the QOL in WDEIA patients from Central China. Twenty-eight WDEIA patients were analyzed, and QOL was measured by validated Chinese version Food Allergy Quality of Life Questionnaire-Adult Form (FAQLQ-AF) and Food Allergy Independent Measure (FAIM) after obtaining the diagnosis. The results showed that half of the patients were females. The median onset age was 37 years old. The symptoms occurred within 1 h after wheat ingestion (26/28). Symptoms of anaphylaxis included cutaneous (26/28), respiratory (11/28), gastro-intestinal (5/28) and cardiovascular manifestations (27/28). Skin prick tests were positive to salt soluble (89.3%) and salt insoluble wheat allergen extracts (100%). Positive rate to wheat, gluten and omega-5 gliadin specific IgE was 64.3%, 92.9% and 92.9% respectively. Specific IgE to omega-5 gliadin with a cut-off value 0.83 KU/L offered highly efficient diagnostic criterion for WDEIA (sensitivity: 89.3%; and specificity: 88.9%). The mean scores of FAQLQ-AF and FAIM were 4.70 and 4.98 respectively and level of anti-omega-5 gliadin IgE had positive correlations with FAQLQ scores. Thereby, WDEIA is commonly found in mid-age adults. In most cases, multi-organs especially skin and cardiovascular systems are involved. Salt insoluble wheat allergen skin test and serum specific IgE to gluten and omega-5 gliadin help to diagnose WDEIA. QOL in WDEIA patients is severely impaired.
