Parasites–allergy paradox: Disease mediators or therapeutic modulators
Publication date: Available online 17 March 2015 Source:Journal of Microscopy and Ultrastructure Author(s): Mohammed A. Afifi , Asif A. Jiman-Fatani , Sherif El Saadany , Mahmoud A. Fouad The noticeable phenomenon of an increased frequency of immune-inflammatory disorders, in the industrialized world, has led to the implication of parasitic infections in the pathophysiology of these diseases. Most of the studies investigated the infection connection to allergy have centered on helminthes. Parasitic helminthes are a group of metazoans that are evolutionary diverse, yet converge to evolve common modes of immunomodulation. ...

Anisakis Infection and Allergy in Humans
Publication date: 2015 Source:Procedia Food Science, Volume 5 Author(s): Jelena Ivanovic, Milan Z. Baltic, Marija Boskovic, Natasa Kilibarda, Marija Dokmanovic, Radmila Markovic, Jelena Janjic, Branislav Baltic Compared with other well-studied parasitic diseases, fish-borne parasitic zoonoses do not get enough attention, especially because these zoonoses have been limited for the most part to populations living in low- and middle-income countries in Europe. Human fishery product-borne parasitic diseases caused by nematodes are the results of infection following ingestion of viable parasites, or as allergic reacti...

Eosinophilic Skin Diseases: A Comprehensive Review
Abstract Eosinophilic skin diseases, commonly termed as eosinophilic dermatoses, refer to a broad spectrum of skin diseases characterized by eosinophil infiltration and/or degranulation in skin lesions, with or without blood eosinophilia. The majority of eosinophilic dermatoses lie in the allergy-related group, including allergic drug eruption, urticaria, allergic contact dermatitis, atopic dermatitis, and eczema. Parasitic infestations, arthropod bites, and autoimmune blistering skin diseases such as bullous pemphigoid, are also common. Besides these, there are several rare types of eosinophilic dermatoses with ...

The Role of IgE in Autoimmunity
There is accumulating evidence to suggest that IgE plays a significant role in autoimmunity. The presence of circulating self-reactive IgE in patients with autoimmune disorders has been long known, but at the same time largely understudied. Studies have shown, however, that the increased IgE concentration is not associated with higher prevalence for atopy and allergy in autoimmune diseases like systemic lupus erythematosus. IgE-mediated mechanisms are conventionally known to facilitate degranulation of mast cells and basophils and promote Th2 immunity, mechanisms that are not only central to mounting an appropriate defense...

Effect of ivermectin on allergy-type manifestations in occult strongyloidiasis
The immunomodulatory effects of helminths have been well described. However, there is a relative lack of literature regarding the link between parasites and allergic diseases. A number of patients with allergic symptoms have positive serologic test results for Strongyloides stercoralis.

Hypereosinophilia in Children and Adults: A Retrospective Comparison
Conclusions Although children with HES often present with higher peak eosinophil counts than adults, the differential diagnosis, clinical characteristics, and prognosis of HES are similar in the 2 groups.

Allergens and molecular diagnostics of shellfish allergy
AbstractShellfish belongs to “The Big 8” food groups causing allergy, which often does not outgrow during childhood. Shellfish is one of the main food allergens in adults and constitutes a diverse group of species subdivided into crustaceans and mollusks, which seem to include similar but also different allergens. Several p an-allergens are characterized in detail, including tropomyosin and arginine kinase, responsible for clinical cross-reactivity with other invertebrate allergen sources, embracing mites, insects, and parasites. Currently, at least seven different shellfish allergens have been identified, mostly from ...

Parasitic Infections in Children with Chronic Spontaneous Urticaria
Conclusion: Parasites may cause CSU even in nontropical countries, and remission may only be possible with the treatment of the parasitic infection. The occurrence of abdominal pain points to parasitic infection in patients with CSU. Therefore, we suggest that parasites should be investigated routinely, especially if the patient has gastrointestinal symptoms of CSU in childhood.Int Arch Allergy Immunol 2016;171:130-135

Topical ivermectin improves allergic skin inflammation
ConclusionAltogether, our results show that IVM is endowed with topical anti‐inflammatory properties that could have important applications for the treatment of T‐cell mediated skin inflammatory diseases.This article is protected by copyright. All rights reserved.

Food allergy to the carbohydrate galactose-alpha-1,3-galactose (alpha-gal): four case reports and a review
AbstractUntil recently, food allergies to mammalian meats have been considered to be very rare. The observation that patients not previously exposed to the monoclonal chimeric antibody cetuximab suffered from severe anaphylaxis upon first exposure, led to the identification of galactosealpha- 1,3-galactose as a new relevant carbohydrate allergen. These patients later often suffered from anaphylactic reactions to red meat. Epidemiological data indicated that bites by the tickAmblyomma americanum in the USA, later also byIxodes species in other continents, resulted in sensitisation to alpha-gal. On the other hand, in African...

Molecular diagnosis of allergy to Anisakis simplex and Gymnorhynchus gigas fish parasites.
CONCLUSIONS: The prevalence of hypersensitivity to marine parasite allergens other than Anisakis simplex should be studied, and the most appropriate technique for this is CRD. PMID: 28341528 [PubMed - as supplied by publisher]

New Perspectives on the Diagnosis of Allergy to Anisakis spp.
AbstractPurpose of ReviewTo compare the prevalence of sensitization in different countries based on specific IgE values and to evaluate the use of isolated native or recombinant allergens for diagnosis.Recent FindingsIsolated allergens help in the diagnosis of truly sensitized patients avoiding false positives due to cross-reactions. Their use is therefore highly recommended, especially when used as a combination of several relevant allergens.SummaryThe use of purified allergens allows an accurate diagnosis and this has led to three important findings: (1) in addition to the digestive route of sensitization, occupational a...
