Anaphylaxis Induced by Multiple Sensitization With Hymenoptera Venom:Report of One Case.

Hymenoptera venom-sensitized patients may experience systemic reactions,and severe patients may even present life-threatening symptoms such as collapse and syncope.Here we report a case of anaphylaxis triggered by multiple sensitization with Hymenoptera venom.Clinical diagnosis and allergen testing showed that the patient developed anaphylaxis to wasp and/or fire ant venom.

A Case of Anaphylaxis Caused by Major Royal Jelly Protein 3 of Royal Jelly and Its Cross-Reactivity with Honeycomb.

Purpose: Royal jelly and honeycomb are commonly consumed in China, and anaphylaxis caused by ingestion of royal jelly is rare. To date, there is no report of anaphylaxis after ingestion of royal jelly in China. Its cross-reactivity with honeycomb is still unclear.

Serum IgE profiles in Chinese pollinosis patients with grass pollen sensitisation.

Purpose: Pollen from trees, grasses, and weeds is a common allergen source. The characteristics of pollen allergy in China are obviously different from Europe. Most studies have focused on tree and weed pollen, but there is a paucity of data on grass pollen sensitisation in China.

Hereditary angioedema caused by a premature stop codon mutation in the SERPING1 gene.

Background: Hereditary angioedema with deficient and dysfunctional C1 inhibitor (C1-INH-HAE) is a rare genetic disorder. The majority of the cases with this disease are caused by mutations in the C1-inbitor gene SERPING1 and are classified as type 1 and type 2. We aimed to detect mutations in the SERPING1 gene and evaluate its expression in nine probands with hereditary angioedema from nine different families.

Retrospective analysis of epidemic thunderstorm asthma in children in Yulin, northwest China.

Background: An epidemic of thunderstorm asthma in pediatric patients occurred in Yulin, a northwest city of China, on 11 September 2018. We described the epidemic and retrospectively analyzed the demographic and clinical aspects of the involved children.

Methods: The caseload data of patients were collected from the hospital information system in Yulin Pediatric Hospital.

Characteristics of pollen-related food allergy based on individual pollen allergy profiles in the Chinese population.

Background: Patients with pollinosis are often multi-sensitized to diverse pollen allergens. However, little is known about pollen allergy types among Chinese pollinosis patients. This study is aimed to characterize clinical manifestations of food allergy among patients with different types of pollen allergy.

Stinging Insect Allergens.

Hymenoptera venom allergy is one of the common causes of anaphylaxis. However, when physicians make the diagnosis of Hymenoptera venom allergy, the history of being stung is not always consistent with the results of venom-specific IgE. With the development of component-resolved diagnosis, it is possible to accurately localize an allergic reaction to certain sensitized proteins.

Wheat allergy in patients with recurrent urticaria.

Background: Clinical observation revealed that most of wheat-induced anaphylaxis (WIA)/wheat-dependent exercise-induced anaphylaxis (WDEIA) patients showed a history of recurrent urticaria. We aim to determine the association between recurrent urticaria and anaphylaxis in wheat allergy.

Methods: Population-based cohort study involved patients with WIA (n = 193, including WDEIA n = 104), recurrent urticaria (n = 177), non-wheat-related anaphylaxis (n = 584), atopic disease (excluding anaphylaxis, n = 221) and healthy control (n = 95) from 2009 to 2016.

Identification of a thermal stable allergen in yam () to cause anaphylaxis.

Yam () is commonly consumed in East Asia, but allergic reaction to this plant food is rare. To date, there is no report of anaphylactic reaction after ingestion of cooked yam. We described 3 cases with anaphylaxis after eating boiled yam and 1 present with oral allergy syndrome as well.

Upper airway edema in 43 patients with hereditary angioedema.

Background: Upper airway edema (UAE) occurs infrequently in hereditary angioedema (HAE), but still results in significant morbidity and mortality.

Objective: To assess patients with HAE and UAE to determine whether unique features exist that can predict the risk of UAE.

Methods: Clinical, laboratory, and genetic data were compared between 43 patients with HAE and 743 UAE attacks and those without UAE and normal controls after ethics committee approval.

Clinical features of hereditary angioedema in Chinese patients: new findings and differences from other populations.

Background: Hereditary angioedema (HAE), caused by C1 inhibitor deficiency, is characterized by recurrent subcutaneous or submucosal swelling. Because it is rare, data on clinical features, especially in Chinese patients, are not comprehensive.

Objective: Our aim was to identify the characteristics of HAE in a Chinese population and enhance clinical knowledge of this disease.

Recent advances in the management of hereditary angioedema.

Hereditary angioedema (HAE) is a rare genetic condition that manifests as painful and potentially life-threatening episodic attacks of cutaneous and submucosal swelling. It results from functional deficiency of C1 inhibitor (C1 INH), which is a regulator of the complement, fibrinolytic, kinin (contact), and coagulation systems. In patients with HAE, the low plasma concentration of functional C1 INH leads to overactivation of the kinin cascade and local release of bradykinin.
