Very early exposure to certain components of air pollution can increase the risk of developing a cockroach allergy by age 7 and children with a common mutation in a gene called GSTM may be especially vulnerable. http://medicalxpress.com/news/2013-02-air-pollution-primes-children-asthma-related.html Immunology Wed, 06 Feb 2013 00:20:02 EST news279307574 Egg allergic children, including those with a history of anaphylaxis to egg, can safely receive a single dose of the seasonal influenza vaccine, according to a new study from the University of Michigan. http://medicalxpress.com/news/2013-01-children-egg-allergies-safely-flu.html Immunology Tue, 22 Jan 2013 10:11:42 EST news278071893 (Medical Xpress)—Many illnesses, including psoriasis, include inflammatory responses that occur without an apparent infection and worsen with stress. In a study using cultured human mast cells in vitro and in rats, researchers from Tufts University School of Medicine and the Sackler School of Graduate Biomedical Sciences at Tufts University identified mitochondrial particles—secreted from live, activated mast cells—as a possible trigger of the inflammation that is common in such illnesses. http://medicalxpress.com/news/2013-01-mitochondrial-components-trigger-auto-inflammatory-illnesses.html Inflammatory disorders Wed, 02 Jan 2013 09:01:05 EST news276339657 Chestnuts roasting on an open fire, candles filling the air with the smell of cinnamon and beloved decorations making their yearly appearance really do help make the season bright.

Sufferers are plagued by swelling and reddening or itching in the mouth and throat area, for example when they eat certain foods, especially apples, but also nuts, peaches or kiwis. A group of researchers at the Institute of Pathophysiology and Allergy Research at the MedUni Vienna, led by Barbara Bohle, has now discovered that the "apple allergy" can be treated effectively with an apple allergen (Mal d 1) and this helps to significantly reduce the symptoms of the condition.  http://medicalxpress.com/news/2012-10-apple-allergy-symptoms-significantly-apple-allergen.html Immunology Fri, 19 Oct 2012 09:00:03 EST news269854188 Researchers are developing a new vaccine for hayfever which could be more effective, less invasive for patients and less expensive than vaccines already available to patients within the NHS. http://medicalxpress.com/news/2012-09-hayfever-vaccine-allergy-treatment-clinical.html Diseases, Conditions, Syndromes Mon, 10 Sep 2012 19:00:04 EST news266515889 (Medical Xpress)—Researchers at King's have established a significant link between asthma and an immune response called 'Th17', previously only attributed to inflammatory conditions such as multiple sclerosis. http://medicalxpress.com/news/2012-08-reveals-link-asthma.html Immunology Thu, 23 Aug 2012 08:49:34 EST news264930563 Young children with allergies to milk and egg experience an unexpectedly high number of reactions to these and other foods, according to researchers at National Jewish Health. More than 70 percent of preschool children with documented or suspected food allergies suffered a significant reaction during the three-year period. Researchers also found that caregivers failed to administer the medication epinephrine in 70 percent of the severe and potentially life-threatening reactions. The study, conducted by the NIH-funded Consortium of Food Allergy Research, is published in the June 25, 2012, issue of the journal Pediatrics. http://medicalxpress.com/news/2012-06-severe-reactions-food-common-thought.html Pediatrics Mon, 25 Jun 2012 03:00:01 EST news259811457 Declining biodiversity may be contributing to the rise of asthma, allergies, and other chronic inflammatory diseases among people living in cities worldwide, a Finnish study suggests. Emerging evidence indicates that commensal microbes inhabiting the skin, airway, and gut protect against inflammatory disorders. However, little is known about the environmental determinants of the microbiome. http://medicalxpress.com/news/2012-05-biodiversity-loss-allergies-asthma.html Inflammatory disorders Mon, 07 May 2012 15:00:20 EST news255608336 Asthma is a chronic inflammatory and respiratory disease caused by an abnormal reactivity to allergens in the environment. Of the several avenues of exploration that are currently being developed, vaccination appears to be the most promising approach. In a publication soon to appear in the review Human Gene Therapy, the research scientists at Inserm and CNRS ( Institut du thorax, CNRS, France) reveal an innovatory vaccine against one of the allergens most frequently encountered in asthma patients. After vaccine was directly injected into the muscle of an asthmatic mouse, a nanovector significantly reduced both the hypersensitivity to the allergen and the associated inflammatory response. http://medicalxpress.com/news/2012-04-asthma-vaccination-intramuscular.html Inflammatory disorders Wed, 04 Apr 2012 10:22:50 EST news252753756 (HealthDay) -- An immunologically-enhanced subcutaneous immunotherapy (SCIT) formulation, with an optimized ratio of allergen to adjuvant, induces a significant immunologic response with acceptable safety when injected every three to four days compared with standard weekly injections, according to a study published online March 3 in Allergy. http://medicalxpress.com/news/2012-03-fast-updosed-subcutaneous-immunotherapy-effective.html Immunology Fri, 16 Mar 2012 05:50:02 EST news251093438 Scientists at the University of Gothenburg, Sweden, have used advanced light microscopy to show that a substance can be differently absorbed by the skin, depending on what it is mixed with.

This finding in mice could have future implications for the treatment of atopic dermatitis, a chronic inflammatory skin disease that affects an estimated 10 to 20 percent of infants and young children. The research is by investigators at the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), part of the National Institutes of Health. http://medicalxpress.com/news/2011-10-immune-cell-dual-role-allergic.html Medical research Tue, 18 Oct 2011 10:10:25 EST news238151413 Some fundamental questions in allergy remain unanswered.
