New Study by McGill University Health Centre: Increasing cases of anaphylaxis among children

Anaphylaxis, known to be a sudden and potentially life-threatening allergic reaction, seems to be increasing among children, according to a new study led by a team at the Research Institute of the McGill University Health Centre (RI-MUHC). The findings, published this week in theJournal of Allergy and Clinical Immunology (JACI), reveal that the percentage of emergency department (ED) visits due to anaphylaxis doubled over a four-year period based on data collected from the Montreal Children’s Hospital of the MUHC (MCH-MUHC).

An international team of scientists, led by Prof. Roger Anderson from the University of Ulster at Coleraine and the NIHR Biomedical Research Centre at Moorfields Eye Hospital NHS Foundation Trust and UCL Institute of Ophthalmology, has designed a test that can spot the first stages of sight loss in age-related macular degeneration. Read More

A recent study by the American Thoracic Society (ATS)  takes a deeper look at the connection between childhood asthma and peanut allergies.  There certainly has been some discussion, focus, and research in the recent years and months focusing on peanut allergies, why children are developing them, and how they can be prevented or avoided.  This study revealed that many children who have asthma have a sensitivity to peanuts.  Many of the respiratory symptoms of peanut allergy and asthma go hand in hand, in fact they mirror each other. Observing and testing a select cohort of children with asthma at a pulmonary clinic lead scientists and researchers to conclude that prevalence of peanut sensitivity was high. Since many of the children and their families did not suspect such an allergy, it is concluded that screening asthmatic children for peanut sensitivity may help to improve their treatment particularly in cases that have been difficult to manage.  Read More

Oxidized Low-Density Lipoprotein Contributes to Atherogenesis via Co-activation of Macrophages and Mast Cells

Study Summary:

Static and microfluidic flow experiments were performed to investigate the number of adherent monocytes on vascular endothelium that are activated by supernatants of oxLDL-treated macrophages and mast cells or directly by oxLDL. Based on results from this study, it was discovered that the degranulation of mast cells during allergy attacks could lead to increases in the histamine concentration near or inside atherosclerotic lesions.  In fact, the amount of histamine that is released can be significantly more than that produced by oxLDL-activated mast cells. Therefore, this suggests that allergy attacks can cause weakening of the endothelium already exposed to TNF-α and histamine from oxLDL-activated macrophages and mast cells.

The final conclusion from this study was that individuals with allergy or asthma who have an elevated amount of histamine in tissues are in fact at very high risk for atherosclerosis and cardiovascular disease if they also have a lipid-rich diet. Other recent studies support this data and point out that allergy and asthma contribute to the development of atherosclerosis.
