Insect Migration and Changes in Venom Allergy due to Climate Change.

Insects are highly successful animals. They have limited ability to regulate their temperature and therefore will expand range in response to warming temperatures. Climate change and associated rising global temperature is impacting the range and distribution of stinging insects.

Hymenoptera allergy and anaphylaxis: are warmer temperatures changing the impact?

Purpose Of Review: Climate change has brought about many changes in our ecosystem. Prolongation of pollen seasons has been reported, related to earlier frost off in the spring and later onset of frost on in the fall. This review considers recent global evidence that stinging insects are redistributing toward the poles, thereby potentially increasing human exposure and risk of sting events.

Impact of weather and climate change with indoor and outdoor air quality in asthma: A Work Group Report of the AAAAI Environmental Exposure and Respiratory Health Committee.

Weather and climate change are constant and ever-changing processes that affect allergy and asthma. The purpose of this report is to provide information since the last climate change review with a focus on asthmatic disease. PubMed and Internet searches for topics included climate and weather change, air pollution, particulates, greenhouse gasses, traffic, insect habitat, and mitigation in addition to references contributed by the individual authors.

Climate Change and the Impact on Respiratory and Allergic Disease: 2018.

Purpose Of Review: The purpose of this paper is to review allergic respiratory disease related to indoor and outdoor exposures and to examine the impact of known and projected changes in climate. The global burden of disease directly attributed to climate change is very difficult to measure and becomes more challenging when the capacity of humans to adapt to these changes is taken into consideration. Allergic respiratory disease, such as asthma, is quite heterogenous, though closely associated with environmental and consequently immunologic interaction.

Successful desensitization of a patient with aplastic anemia to antithymocyte globulin.

Antithymocyte globulin (ATG) is a polyclonal gamma immunoglobulin derived from either rabbit or equine serum that serves as therapy for aplastic anemia; however, ATG causes serum sickness in up to 70% and anaphylaxis in up to 5% of recipients. Intradermal (ID) skin testing has been the primary technique used to evaluate for a preexisting Gell and Coombs type I hypersensitivity reaction to ATG. There are no data reporting the predictive value of delayed reactions to ID testing on the risk of serum sickness.

Allergic bronchopulmonary aspergillosis.

There remains a lack of agreement on diagnostic criteria and approaches to treatment of patients with allergic bronchopulmonary aspergillosis (ABPA). The results of a survey of American Academy of Allergy, Asthma, & Immunology members regarding these 2 issues are presented and compared for concordance with published recommendations. The literature was reviewed for pertinent reports, and an electronic survey was conducted of American Academy of Allergy, Asthma, & Immunology members and fellows regarding diagnostic criteria, numbers of patients evaluated for ABPA, and treatment approaches.

Twin and family studies reveal strong environmental and weaker genetic cues explaining heritability of eosinophilic esophagitis.

Background: Eosinophilic esophagitis (EoE) is a chronic antigen-driven allergic inflammatory disease, likely involving the interplay of genetic and environmental factors, yet their respective contributions to heritability are unknown.

Objective: To quantify the risk associated with genes and environment on familial clustering of EoE.

Methods: Family history was obtained from a hospital-based cohort of 914 EoE probands (n = 2192 first-degree "Nuclear-Family" relatives) and an international registry of monozygotic and dizygotic twins/triplets (n = 63 EoE "Twins" probands).

Climate change and our environment: the effect on respiratory and allergic disease.

Climate change is a constant and ongoing process. It is postulated that human activities have reached a point at which we are producing global climate change. It provides suggestions to help the allergist/environmental physician integrate recommendations about improvements in outdoor and indoor air quality and the likely response to predicted alterations in the earth's environment into his or her patient's treatment plan.

Insect anaphylaxis: where are we? The stinging facts 2012.

Purpose Of Review: Insect allergy remains an important cause of morbidity and mortality in the United States. In 2011, the third iteration of the stinging insect hypersensitivity practice parameter was published, the first being published in 1999 and the second in 2004. Since the 2004 edition, our understanding of insect hypersensitivity has continued to expand and has been incorporated into the 2011 edition.

Fungi and allergic lower respiratory tract diseases.

Asthma is a common disorder that in 2009 afflicted 8.2% of adults and children, 24.6 million persons, in the United States.

Insect anaphylaxis: addressing clinical challenges.

Purpose Of Review: Few allergic reactions are as potentially life-threatening, or frightening to the patient, as anaphylaxis. Food, medications, and insect stings are the three most common triggers of anaphylaxis, but insect allergy provides the best opportunity to understand the biology of anaphylaxis. If the physician can establish a diagnosis of insect allergy, treatment with nearly 98% effectiveness can be initiated.

Increasing insect reactions in Alaska: is this related to changing climate?

In 2006, Fairbanks, AK, reported its first cases of fatal anaphylaxis as a result of Hymenoptera stings concurrent with an increase in insect reactions observed throughout the state. This study was designed to determine whether Alaska medical visits for insect reactions have increased. We conducted a retrospective review of three independent patient databases in Alaska to identify trends of patients seeking medical care for adverse reactions after insect-related events.

Seal and whale meat: two newly recognized food allergies.

Background: Alaska's marine mammals compose a large portion of the diet of indigenous coastal Alaskan people. Bowhead whales (Balaena mysticetus) and bearded seals (Erignathus barbatus), inhabitants of the Bering and Beaufort seas along Alaska's western and northern coasts, are 2 of the most important subsistence species, serving as major food sources to the native population.

Objective: To describe an Inupiaq boy with symptoms consistent with an IgE-mediated food allergy after ingestion of bowhead whale and bearded seal meat.

Cross-reactivity between allergens in the venom of the common striped scorpion and the imported fire ant.

Background: The common striped scorpion, Centruroides vittatus, and the imported fire ant (IFA) are endemic to the south-central United States. There is evidence of venom-specific IgE in patients experiencing hypersensitivity reactions to scorpion stings. The infrequency of repeated scorpion stings and the presence of immediate reactions to an initial sting suggest prior sensitization.
