CONTEXT: Diospyros kaki L. (Ebenaceae) fruit is widely distributed in Asia and is known to exert anti-inflammatory and antithrombotic effects. OBJECTIVE: We evaluated the inhibitory effect of aqueous extract of D. kaki calyx (AEDKC) on mast cell-mediated immediate-type hypersensitivity and underlying mechanism of action. MATERIALS AND METHODS: For in vivo, ovalbumin (OVA)-induced active systemic anaphylaxis (ASA) and immunoglobulin (Ig) E-mediated passive cutaneous anaphylaxis (PCA) models were used...

Hypersensitivity to human seminal plasma is rare, but probably under-diagnosed. It should be suspected in women with unexplained anaphylaxis, vulvo-vaginitis, pelvic pain and dyspareunia. The diagnosis relies on the clinical presentation, the exclusion of other causes, a positive skin test result to seminal plasma and the detection of IgE directed to allergenic proteins (such as prostate specific antigen). Use of condoms is the best preventive measure. Premedication with antihistamines or anti-inflammatory agents is often unreliable...

Food-dependent exercise-induced anaphylaxis (FDEIA) is a potentially severe food allergy. Physical exercise, NSAID, alcohol, infectious diseases and estrogens are recognized cofactors, able to reduce the amount of allergen needed to achieve a threshold for the induction of anaphylaxis. Various kinds of causative food but only a few responsible proteins have been identified. The best known is wheat ω5-gliadine. An oral food challenge remains the gold standard to prove the diagnosis. Its clinical application remains difficult and includes an allergen challenge, a cofactor challenge and a third step which integrates both of them in a single test...

Adverse reactions (ARs) to intravenous (IV) radiographic contrast range from mild urticaria to life-threatening anaphylaxis. Intraluminal contrast dye is routinely used in the urinary tract with a minimal perceived risk of AR. We used the Healthcare Cost and Utilization Project State Inpatient Databases for California and Florida from 2007 to 2011 to identify patients who received urinary tract contrast dye for retrograde pyelography, percutaneous pyelography, retrograde/other cystogram, and ileal conduitogram...

PURPOSE OF REVIEW: This review aims to describe current concepts in managing patients with food allergy. There have been many recent advances in the management of patients with IgE-mediated reactions to food, including diagnosis, prevention, management, and ongoing research in the field. Food allergy is increasing in prevalence and may be life threatening. This review aims to highlight changes in recommended practice when diagnosing and managing patients with food allergy. RECENT FINDINGS: Early introduction of highly allergenic foods, particularly peanut, has been shown to decrease the risk for development of food allergy in patients who are at elevated risk...

Asthma is characterized by chronic inflammation, goblet cell hyperplasia, the aberrant production of the Th2 cytokines, and eosinophil infiltration into the lungs. In this study, we examined the effects of baicalein, wogonin, and Scutellaria baicalensis ethanol extract on ovalbumin (OVA)-induced asthma by evaluating Th1/Th2 cytokine levels, histopathologic analysis, and compound 48/80-induced systemic anaphylaxis and mast cell activation, focusing on the histamine release from rat peritoneal mast cells. Baicalein, wogonin, and S...

Diagnostic and therapeutic reagents are unavailable for anaphylaxis arising from stings by Apis dorsata. Venom profiles and cross-reactivity of A. dorsata and Apis mellifera were compared, to ascertain whether venom of A. mellifera can be used for diagnosis in A. dorsata allergy. Both venom profiles were similar by High Performance Liquid Chromatography and SDS-PAGE. Sera of 29 of 30 (96.7%) patients with anaphylaxis to A. dorsata stings had IgE to the phospholipase-2 (PLA2) doublet (15 and 16 kDa) of A...

Although death from food is not an uncommon finding in forensic facilities worldwide, the range of underlying lethal mechanisms and associated conditions that should be sought at the time of autopsy is quite disparate. Deaths may occur from i) infectious agents including bacteria, viruses, protozoa, cestodes, nematodes and prions; ii) natural toxins including amanita toxins, tetrodotoxin, ciguatera and scombroid; iii) anaphylaxis; iv) poisoning; v) mechanical issues around airway and gut obstruction and/or perforation; and vi) miscellaneous causes...

OBJECTIVES: Iron deficiency anemia (IDA) is a common complication of pediatric inflammatory bowel disease (IBD), yet the effectiveness of oral iron supplementation is limited. Intravenous iron sucrose is an effective and safe alternative treatment for IDA in adults with IBD, but its role in the treatment of IDA in pediatric IBD is unclear. The primary aim of this study was to evaluate the use of iron sucrose in pediatric IBD subjects with IDA and determine the clinical response as measured by improvement in hemoglobin concentration...

We report a case of jellyfish allergy diagnosed via an oral food challenge. A 14-year-old boy had no history of jellyfish stings and had been eating commercially available jellyfish products twice yearly for the past 5-6 years. Five minutes after eating a commercially available boiled jellyfish product (100g), he experienced nausea, wheezing, and erythema and had visited our hospital. We suspected an anaphylactic reaction and treated him with intramuscular adrenaline injection, corticosteroid and antihistamine infusions, volume resuscitation, and salbutamol sulfate inhalation, which resulted in an improvement of the symptoms...
