IgE Test in Secretions of Patients with Respiratory Allergy

AbstractPurpose of ReviewIgE is a key player in multiple inflammatory airway diseases. Ample literature demonstrates its presence in mucosa of patients with allergic rhinitis (AR), local allergic rhinitis (LAR), asthma, or chronic rhinosinusitis with nasal polyposis (CRSwNP).Recent FindingsCurrent evidence shows that high-affinity IgE in blood stream of allergic individuals derives mainly from the mucosae. Also, mucosal synthesis of IgE can occur in the absence of systemic atopy, and may be relevant in atopic and non-atopic phenotypes of rhinitis as demonstrated in LAR. Specific IgE (sIgE) detection varies depending on technique used for sample collection and its measurement. sIgE detection is highly specific for diagnosis of LAR. Moreover, measurement of sIgE in secretions could be useful in monitoring response to allergen-specific immunotherapy in both AR and LAR phenotypes.SummaryThis review will focus on recent developments in the role of IgE in respiratory diseases, and the clinical implications of its measurement in secretions.

When I worked at Greenpeace for five years before I attended medical school, a popular slogan was, “think globally, act locally.” As I write this blog about climate change and hay fever, I wonder if wiping off my computer that I’ve just sneezed all over due to my seasonal allergies counts as abiding by this aphorism? (Can you clean a computer screen with a tissue?) Come to think of it, my allergies do seem to be worse in recent years. So do those of my patients. It seems as if I’m prescribing nasal steroids and antihistamines, recommending over-the-counter eye drops, and discussing ways to avoid all...

AbstractPurpose of reviewThe aim of this paper is to review and summarise the current knowledge of prevention of house dust mite (HDM)-induced allergic rhinitis (AR).Recent findingsAR can be either classified as seasonal/intermittent (for example hay fever occurring summer and autumn) or perennial/persistent (occurring throughout the year). The commonest trigger for seasonal AR is pollen whereas HDMs are the key allergic trigger for perennial AR. HDMs are a recognised indoor allergen that is crucial in the development of AR, asthma, and atopic dermatitis.SummaryPreventive strategies have gained acceptance for the managemen...

Abstract Allergic rhinitis is a common disorder that regularly occurs in children and adolescents. The disease is associated with other allergic diseases, such as asthma, and it carries a heavy burden, with effects on sleep, school performance, and quality of life. Classic symptoms include sneezing, rhinorrhea, nasal obstruction, and nasal itching. When the eyes are involved, the term allergic rhinoconjunctivitis is used. Triggers may include airborne pollens, molds, dust mites, and animals. Skin or blood allergy testing can be a useful diagnostic modality that may guide therapy. Immunotherapy can prevent the deve...

CONCLUSIONS: Standardized house dust mite extract was more effective than non-standardized house dust extract for subcutaneous immunotherapy; however, the establishment of safer methods is warranted. PMID: 31308334 [PubMed - in process]

Subcutaneous allergen immunotherapy (SCIT) is effective for allergic rhinitis, allergic conjunctivitis, and allergic asthma1. Local reactions are the most common adverse effect associated with SCIT1, though systemic reactions to SCIT (SCITSR) are the most serious adverse effect1. The rate of systemic reactions to SCIT with a conventional dosing schedule is reported to be 0.1-0.2% per injection.1,2 It is generally accepted that the potential benefits of SCIT for select atopic conditions outweigh this risk of SCITSR.

AbstractAllergen immunotherapy (AIT) for allergic rhinitis (AR), asthma, and other allergic diseases has developed quickly. House dust mite (HDM),Artemisia (wormwood),Humulus japonicus (Japanese hop),Alternaria alternata, andCladosporium herbarum are the five most common inhalant allergens in China. AIT has been performed in China for over 60  years. With the support of the Chinese Medical Association (CMA) and the Chinese Medical Doctors Association (CMDA), the Chinese College of Allergy and Asthma (CCAA) was established in 2016 as a specialized branch of CDMA and is the main certification authority for AIT. Chinese ...

AbstractPQ Grass represents an allergen ‐specific immunotherapy for pre‐seasonal treatment of patients with seasonal allergic rhinitis (or rhinoconjunctivitis) with or without mild‐to‐moderate bronchial asthma. It consists of a native pollen extract for 13 grass species, chemically modified with glutaraldehyde, and adsorbed tol‐tyrosine in a microcrystalline form with addition of the adjuvant Monophosphoryl Lipid A (MPL®). Previous non ‐clinical safety testing, including rat repeat dose toxicity in adult and juvenile animals, rat reproductive toxicity and rabbit local tolerance studies showed no safety find...

Abstract IgE is the less abundant immunoglobulin isotype in serum and displays higher affinity for its cognate Fc receptor (FcεRI) than the rest of antibody isotypes. Moreover, the class switch recombination and the generation of memory responses remarkably differ between IgE and other isotypes. Importantly, class switch recombination to IgE can occur in the mucosae, preferentially through the sequential switching from IgG. Therefore, resident effector cells get rapidly sensitized, and free IgE can be found in mucosal secretions. All these aspects explain the involvement of IgE in respiratory diseases. In ...

ConclusionsCompared to placebo, AIT with DPAEs is effective in patients with pollen- or HDM-induced rhinoconjunctivitis with or without allergic asthma and improves health-related quality of life. It does not differ significantly in safety and tolerability.
