Patients with autosomal dominant vibratory urticaria have localized hives and systemic manifestations in response to dermal vibration, with coincident degranulation of mast cells and increased histamine levels in serum. We identified a previously unknown missense substitution in ADGRE2 (also known as EMR2), which was predicted to result in the replacement of cysteine with tyrosine at amino acid position 492 (p.C492Y), as the only nonsynonymous variant cosegregating with vibratory urticaria in two large kindreds. The ADGRE2 receptor undergoes autocatalytic cleavage, producing an extracellular subunit that noncovalently binds a transmembrane subunit. We showed that the variant probably destabilizes an autoinhibitory subunit interaction, sensitizing mast cells to IgE-independent vibration-induced degranulation.

Papain Induced Occupational Asthma with Kiwi and Fig Allergy

Allergy, Asthma & Immunology Research 2016, 8 (2): 170-3

Nannan Jiang, Jia Yin and Liping Wen

Abstract

Papain is a proteolytic enzyme which is widely used in food industry, pharmaceuticals, and cosmetics. Occupational and non-occupational papain allergies have previously been documented; however, there are limited publications about papain allergy with its relative fruit allergy. Here, we present a case of occupational, IgE-mediated papain allergy with kiwi fruit and fig fruit allergy.

One-year survey of paediatric anaphylaxis in an allergy department

Volume 47 n. 6/2015  November 2015

Â. Gaspar, N. Santos, S. Piedade, C. Santa-Marta, G. Pires, G. Sampaio, C. Arêde, L.M. Borrego, M. Morais-Almeida

Aim. To determine the frequency of anaphylaxis in an allergy outpatient department, allowing
a better understanding regarding aetiology, clinical manifestations and management, in children and adolescents. Methods. From among 3646 patients up to 18 years old observed during one-year period, we included those with history of anaphylaxis reported by allergists.

Abstract

Background

Skin tests for neuromuscular blocking agents (NMBAs) are not currently recommended for the general population undergoing general anaesthesia. In a previous study we have reported a high incidence of positive allergy tests for NMBAs in patients with a positive history of non-anaesthetic drug allergy, a larger prospective study being needed to confirm those preliminary results. The objective of this study was to compare the skin tests results for patients with a positive history of antibiotic-induced immediate type hypersensitivity reactions to those of controls without drug allergies.

Abstract

Medications can cause many adverse reactions, both non-immunologic and immunologic ones. Allergies can take many forms, allergic reactions include all types of reactions according to Gell and Coombs. Typically, allergic reactions to drugs are manifested by skin lesions such as maculopapular rash or urticaria and life-threatening systemic reactions such as anaphylaxis.

          Farm environment has been shown to protect from childhood asthma. Underlying immunological mechanisms are not clear yet, including the role of dendritic cells (DCs). The aim was to explore whether asthma and farm exposures are associated with the proportions and functional properties of DCs from 4.5-year-old children in a subgroup of the Finnish PASTURE birth cohort study.
          

Parent-determined oral montelukast therapy for preschool wheeze with stratification for arachidonate 5-lipoxygenase (ALOX5) promoter genotype: a multicentre, randomised, placebo-controlled trial

Headline

The study found no clear benefit of intermittent montelukast in young children with wheeze. Further research is need to determine if a variant allele of ALOX5 identifies individuals who are more responsive to montelukast.

Abstract

Background:

The clinical effectiveness of intermittent montelukast for wheeze in young children is unclear. Previous work has been equivocal. Variation in copy numbers of the specificity protein 1-binding motif in the arachidonate 5-lipoxygenase (ALOX5) gene promoter
