Effect of ivermectin on allergy-type manifestations in occult strongyloidiasis.
CONCLUSION: Serologic testing for strongyloides may be indicated for patients with allergy-type symptoms and a suggestive exposure history. Patients with strongyloidiasis and primarily cutaneous symptoms experienced significant symptomatic improvement after ivermectin therapy.

Migrants and allergy: a new view of the atopic march.
Authors: Biagioni B, Vitiello G, Bormioli S, Tarrini D, Lombardi C, Rossi O, Parronchi P
Abstract
Summary: Atopy is the result of the influence of environmental factors on genetically predisposed individuals. Migration flows represent an interesting model to study the possible reciprocal roles of genes and environment. In this review the following issues influencing the development of allergic sensitization and/or atopic disorders in migrants will be rooted out: 1) ethnicity, genetic polymorphisms and risk of atopy; 2) double faceted effects of parasitic infestations; 3) biodiversity loss and industrial progress. M...

Clinical Management of Seafood Allergy
Publication date: January 2020Source: The Journal of Allergy and Clinical Immunology: In Practice, Volume 8, Issue 1Author(s): Carla M. Davis, Ruchi S. Gupta, Ozge N. Aktas, Veronica Diaz, Sandip D. Kamath, Andreas L. LopataSeafood plays an important role in human nutrition and health. A good patient workup and sensitive diagnostic analysis of IgE antibody reactivity can distinguish between a true seafood allergy and other adverse reactions generated by toxins or parasites contaminating ingested seafood. The 2 most important seafood groupings include the fish and shellfish. Shellfish, in the context of seafood consumption,...

Influence of Parasitic Worm Infections on Allergy Diagnosis in Sub-Saharan Africa
AbstractEpidemiological studies from Sub-Saharan Africa indicate that allergies are on the rise in this region especially in urban compared to rural areas. This increase has been linked to improved hygiene, lifestyle changes, and lower exposure to pathogens in childhood. Reduced exposure to parasitic worm (helminth) infections and allergy outcomes has been the focus of a number of population studies over the years. Paradoxically, there are parallels in the immune responses to helminths and to allergies. Both conditions are associated with elevated levels of immunoglobulin E, high numbers of T helper 2 cells, eosinophils, a...

Effect of polymorphisms on TGFB1 on allergic asthma and helminth infection in an African admixed population.
CONCLUSION: Individuals with TGF-β1 polymorphisms have an increased susceptibility to helminth infections and a lower risk of developing allergy. These studies suggest that immune modulation of allergic disease results not only from environmental factors but also from genetic susceptibility and IL-10 production.

Global issues in allergy and immunology: Parasitic infections and allergy
Allergic diseases are on the increase globally in parallel with a decrease in parasitic infection. The inverse association between parasitic infections and allergy at an ecological level suggests a causal association. Studies in human subjects have generated a large knowledge base on the complexity of the interrelationship between parasitic infection and allergy. There is evidence for causal links, but the data from animal models are the most compelling: despite the strong type 2 immune responses they induce, helminth infections can suppress allergy through regulatory pathways.

Peanut-specific IgE antibodies in asymptomatic Ghanaian children possibly caused by carbohydrate determinant cross-reactivity
Background: The prevalence of peanut allergy has increased in developed countries, but little is known about developing countries with high peanut consumption and widespread parasitic infections.Objective: We sought to investigate peanut allergy in Ghana.Methods: In a cross-sectional survey among Ghanaian schoolchildren (n = 1604), data were collected on reported adverse reactions to peanut, peanut sensitization (serum specific IgE and skin reactivity), consumption patterns, and parasitic infections. In a subset (n = 43) IgE against Ara h 1, 2, 3, and 9 as well as cross-reactive carbohydrate determinants (CCDs) was measu...

Hyperimmunoglobulinemia E and efficacy of elimination diet in two patients with Schnitzler syndrome.
CONCLUSION: The high serum levels of total IgE may be associated with chronic urticaria activity, severe disease course and a poor response to treatment with antihistamines, and may be considered a possible marker of a subset of patients with SS showing a good response to the restriction diet. In general, we can assume that elimination diet can have an influence on the skin lesions and other symptoms of SS as well as on total IgE and IgM levels, but such association, the underlying mechanisms and the reasons for excessive IgE synthesis should be investigated in further studies.

Ani s 11-Like Protein Is a Pepsin- and Heat-Resistant Major Allergen of Anisakis spp. and a Valuable Tool for Anisakis Allergy Component-Resolved Diagnosis
Conclusions: These data indicate that the Ani s 11-like protein is a pepsin- and heat-resistant major allergen (Ani s 11.0201) of Anisakis spp. and a valuable tool for Anisakis allergy component-resolved diagnosis.Int Arch Allergy Immunol 2016;169:108-112

IgE, IgG1 and IgG4 response to specific allergens in sensitized subjects showing different clinical reactivity to Anisakis simplex.
Conclusion. The clinical expression of Anisakis simplex sensitization does not seem to depend on IgE reactivity to a specific allergen of the parasite, nor on the presence of IgG antibodies possibly related with blocking activity.

Progress in Anisakis Allergy Research: Milestones and Reversals
AbstractPurpose of the reviewAnisakis has gained cosmopolitan celebrity mainly through its potential to induce allergic disease. In the last two decades, several regions in the world, including the Mediterranean region, Japan, or Korea have reported high numbers of Anisakiasis-accompanied allergic symptoms: Gastro-allergic Anisakiasis.Recent findingsRecent wide-scale epidemiological studies highlight the global scenario ofAnisakis for human health, and awareness is the main contributing factor. After two decades of research in the field ofAnisakis allergy, in the last years, molecular studies ofAnisakis allergens including...

In vitro Immunobiological Studies of Novel 5-(5-nitrofuran-2-yl)-1, 3, 4-Thiadiazoles with Piperazinyl-Linked Benzamidine Substituents Against Leishmania Major.
Abstract
It was recently demonstrated that 5-(5-nitrofuran-2-yl)-1, 3, 4-thiadiazoles with piperazinyl-linked benzamidine substituents are effective in vitro against Leishmania major.Following on this evidence, we used colorimetric assay of acid phosphatase activity in the promastigotes as an indicator for cell viability. Also we studied the effect of these compounds on induction of nitric oxide (NO) in macrophage and production of reactive oxygen species (ROS) in lymphocyte that have important role in activation of immune response against Leishmania and elimination of parasite.Results showed that these compounds ...

A case of eosinophilic fasciitis presenting as pitting edema of the lower extremities.
We report a 19-year-old female who presented with pitting edema in both lower extremities. She had a history of excessive physical activity before her symptoms developed. Physical examination revealed 2+ pitting edema in both lower legs. She complained of mild pain in both knee joints and feet, with no tenderness or heating sensations. Laboratory results were unremarkable except for severe eosinophilia. Parasite infection, venous thrombosis, and cardiac and renal problems were excluded. A magnetic resonance imaging study of both lower extremities revealed increased signal intensity in the subcutaneous lesions, consistent w...
