An allergy is a reaction by your immune system to something that does not bother most other people. People who have allergies often are sensitive to more than one thing. Substances that often cause reactions are:
Allergies can cause a variety of symptoms such as a runny nose, sneezing, itching, rashes, swelling, or asthma. Allergies can range from minor to severe. Anaphylaxis is a severe reaction that can be life-threatening. Doctors use skin and blood tests to diagnose allergies. Treatments include medicines, allergy shots, and avoiding the substances that cause the reactions.

IgE antibodies bind to mast cells (allergy cells) that live in your skin, respiratory tract (airways) and the mucus membrane in the hollow organs that connect to each other from your mouth to your anus (gastrointestinal or GI tract).
The antibodies find the allergens in your body and help remove them by taking them to the mast cell (allergy cell), where they attach to a special receptor. This causes the allergy cell to release histamine. Histamine is what causes your allergy symptoms.
Skin prick (scratch) tests can identify the allergens that cause your allergy symptoms. An allergist will use a thin needle to prick your skin with a tiny amount of different possible allergens. They then check to see if your skin reacts to the allergen.
Nasal steroid sprays are generally the most effective medication for people with allergic rhinitis symptoms. Antihistamines block some of the effects of histamine and may offer additional benefits. Immunotherapy helps create a tolerance to allergens and can improve many of the symptoms related to inhalant allergy exposure.
The Asthma and Allergy Foundation of America (AAFA), a not-for-profit organization founded in 1953, is the leading patient organization for people with asthma and allergies, and the oldest asthma and allergy patient group in the world.
Alpha-gal syndrome (AGS) (also called alpha-gal allergy, red meat allergy, or tick bite meat allergy) is a serious, potentially life-threatening allergic reaction. AGS is not caused by an infection. AGS symptoms occur after people eat red meat or are exposed to other products containing alpha-gal.

At Langford Allergy, we are passionate about offering a patient-centered approach to medical care at our locations in Macon, Warner Robins, Milledgeville, and Forsyth. Dr. Jeffrey Langford opened Langford Allergy in February 2014 with the vision of providing adults and children in Middle Georgia with the highest quality allergy, asthma, and immunology diagnostic and therapeutic services.
The official publication of the World Allergy Organization, the World Allergy Organization Journal (WAOjournal) publishes original mechanistic, translational, and clinical research on the topics of allergy, asthma, anaphylaxis, and clinical immunology, as well as reviews, guidelines, and position papers that contribute to the improvement of patient care.

The most common triggers of anaphylaxis include foods, medications, insect stings, and allergen immunotherapies. Any substance that can trigger the degranulation of mast cells or basophils can induce anaphylaxis. The definition of allergy and anaphylaxis has varied in the past; in 2005, an interprofessional group of clinical experts was formed to improve recognition and designate criteria for the diagnosis of anaphylaxis. The incidence of anaphylaxis varies between 0.5 to 2% in the general population, and the rate has been increasing. The lifetime prevalence is 1.6%.
(Skin symptoms are absent or unrecognized in up to 20 percent of episodes, thus incorporating the other symptoms of gastrointestinal or the listed symptoms improve recognition of anaphylaxis and allergy).
Anaphylaxis is a clinical diagnosis. The chemical mediator measurements are not readily available to the clinician. They can retrospectively confirm the allergic reaction and support the diagnosis. Blood cell counts for the measurement of mast cells, and basophil mediators are also helpful if obtained soon after the onset of symptoms. Some suggest that serial tryptase levels be drawn at 15 minutes, 3 hours, 6hours and 24 hours. If elevated at 24 hours, then referral to allergy/immunology specialists for evaluation of possible systemic mastocytosis or a mast cell activation syndrome is recommended. These patients with mast cell disorders can have hypotensive reactions to insect stings even in the absence of immunoglobulin E (IgE)-mediated allergy. Tryptase measurements have been assessed in patients presenting to the emergency department. A level of 12.4 ng/ml had a high specificity of 88 percent and a positive predictive value of (0.93) and low sensitivity of 28 percent and a negative predictive value (0.17). Anaphylaxis patients with hypotension were more likely to have elevated tryptase levels. Another marker is plasma histamine levels, which peak within 5 to 15 minutes of the onset of symptoms and decrease to baseline in 60 minutes; this is because histamine undergoes rapid metabolism by N-methyltransferase and diamine oxidase. The levels do correlate better with anaphylaxis than tryptase levels. As most patients arrive well beyond the 15 to 60 minutes window to emergency departments, measurement of histamine levels is not practical as they will be back to baseline. A 24-hour urine histamine collection started as soon as possible after anaphylaxis can be helpful. Future tests will focus on mature beta-tryptase over total tryptase and alpha tryptase.
Patients should receive education about anaphylaxis and the emergent treatment needed if recurrence happens. If the causative agent or allergen is known, the patient should be informed as to what it was and told to avoid future exposure. The patient should have training in the use of an epinephrine pen injector and the need to report to the emergency department as soon as possible after exposure. The patient should be made aware of early signs and symptoms of anaphylaxis itching, redness of the skin, hives, runny nose, and advance symptoms trouble breathing, wheezing, vomiting, swelling of the throat and esophagus, diarrhea, and feeling dizzy passing out. The patient may obtain a referral to an allergist/immunologist for further evaluation and treatment. Patients with high sensitivities such as the peanut or legume allergies need education on reading labels of food products. They should recommend allergy bracelets/rescue kits to patients with severe events. The rescue kit usually contains an epinephrine injector device and oral or injectable antihistamine.

Allergies and asthma are on the rise around the world, including in the United States. Allergies occur in all ages and can range from allergic conjunctivitis, allergic rhinitis, allergic asthma, and allergic gastrointestinal disease to drug allergies and food allergies. Severe food allergies are a growing epidemic, with rates having doubled in the last decade. About one in three Americans suffer from some form of allergy, and doctor-diagnosed food allergies affect one in 12 American children under the age of 21 and one in about 50 adults. Of those individuals with a food allergy, approximately 25 percent will have a near-fatal anaphylactic reaction at some point in their lives. It is estimated that $25 billion is spent annually on reactive food allergy care.
The National Academies of Sciences, Engineering, and Medicine convened an expert, ad hoc committee to examine critical issues related to food allergy. The resulting report, released on November 30, 2016, Finding a Path to Safety in Food Allergy: Assessment of the Global Burden, Causes, Prevention, Management, and Public Policy, collects and evaluates the scientific evidence on the prevalence, origins, diagnosis, prevention, and management of food allergy and makes recommendations to policy makers, industry leaders, and others to bring about a safe environment for those with food allergy. 041b061a72
