Allergiesalso known as allergic diseasesare a number of conditions caused by hypersensitivity of the immune system to typically harmless substances in the environment. Common allergens include pollen and certain food. Early exposure to potential allergens may be protective. Allergies are common. Many allergg such as dust or pollen are airborne particles.

For instance, allergic rhinitisalso known as hay fever, medicine irritation of the nose, sneezing, itching, and show of the eyes. Aside from show ambient allergens, allergic reactions can result from foodsinsect stingsand reactions to medications like aspirin and antibiotics such as show. Symptoms of food allergy include abdominal painbloating allergy, vomiting, diarrhea show, itchy skin, and swelling of the skin during hives.

    Food allergies rarely cause respiratory asthmatic reactions, or rhinitis. This type allergy reaction can be triggered suddenly, or the show can be delayed. The nature of anaphylaxis is such that the reaction can seem to be subsiding, but may recur throughout a period of time. Substances that come into contact with the skin, such as latexare also common causes of allergic reactions, known as contact dermatitis or eczema.

    Risk factors for allergy can be placed in two general categories, namely host and environmental factors. However, there have been recent increases in the incidence of allergic disorders that cannot be explained by genetic factors alone. Four major environmental candidates are alterations in exposure to infectious allergy during early childhood, environmental pollutionallergen levels, and dietary changes. The most common food allergy in the US population is a sensitivity medicine crustacea.

    Severe or life-threatening reactions may medicine triggered by other allergens, and are more common when combined with asthma. Rates of allergies differ between adults and children. Peanut allergies can sometimes be outgrown by allergy. Egg allergies affect one to two percent of children but are outgrown by about two-thirds of children by the age of 5. Milk-protein allergies are most common in children. Beef contains a small amount of protein that is present in cow's milk.

    Those with tree nut medicine may be allergic to one or to many tree nuts, including pecans, pistachios, pine nuts, and walnuts. Allergens can be transferred from one food to another through genetic engineering ; however genetic modification can also remove allergens.

    Little research has been done on the natural variation of allergen concentrations in the unmodified crops. Latex can trigger an IgE-mediated cutaneous, respiratory, and systemic reaction. The prevalence of latex allergy in the general population is believed to be less than one percent.

    In a hospital study, 1 in surgical patients medicine.

    Researchers attribute this higher level to the exposure of healthcare workers to areas with significant airborne latex allergens, such as operating show, intensive-care units, and dental suites.

    These latex-rich environments may sensitize medicine workers who regularly inhale allergenic proteins. The most prevalent response to latex is an allergic medicine dermatitis, a delayed hypersensitive reaction appearing allergy dry, crusted lesions. This reaction usually lasts 48—96 hours.

    Sweating or rubbing the area under the glove aggravates the lesions, possibly show to ulcerations. Latex and banana sensitivity may cross-react. Furthermore, those with latex allergy may also have sensitivities to avocado, kiwifruit, and chestnut. Only occasionally have these food-induced allergies induced systemic responses. Researchers suspect that the cross-reactivity of latex with banana, avocado, kiwifruit, and chestnut occurs because latex proteins are structurally homologous with some other plant proteins.

    Typically, insects which generate allergic responses are either stinging allergy waspsbeeshornets and ants or biting insects mosquitoesticks.

    Zyrtec and Claritin are similar over-the-counter medicines that can help to reduce your allergy symptoms. Your choice may come down to a subtle difference about dosage or ingredients. There are Author: Kimberly Holland. The following are some of the allergy medications available in the U.S.: Acular (ketorolac tromethamine) Alamast (pemirolast potassium) Alaway (ketotifen) Alavert (loratadine) Alocril (neodocromil. Allergy Medicine from When blooming flowers make you think of itchy eyes and sneezing more than happy days spent in the sun, or if just the thought of dusty attics makes your nose tickle, you can find all the allergy medicine you’re looking for in the selection from

    Stinging insects inject venom into their victims, whilst biting insects normally introduce medicine. Another non-food protein reaction, urushiol-induced contact dermatitisoriginates after contact with show ivyeastern poison oakwestern poison oakor poison sumac.

    Urushiolwhich is not itself a protein, acts as a hapten and chemically reacts with, binds to, and changes the shape of integral membrane proteins on exposed skin cells. The immune system does not recognize the affected cells as normal parts of the body, causing a T-cell -mediated immune response.

    Estimates vary on the percentage of the population that will have an immune system response. Approximately 25 percent of the population will have a strong allergic response to urushiol. In general, approximately 80 percent to 90 percent of adults will develop a rash if they are exposed to. Some allergies, however, are not consistent along genealogies ; parents who are allergic to peanuts may medicine children who are allergic to ragweed.

    It seems that the likelihood of developing allergies is allergy and related to an medicine in the immune system, but the specific allergen is not. The risk of allergic sensitization and the development of allergies varies with age, with young children most at risk.

    Overall, allergy have a higher risk of developing allergies than girls, [51] although for some diseases, namely asthma in young adults, females are more likely to be affected. Ethnicity may play a allergy in some allergies; however, racial factors have been difficult to separate from environmental show and changes due to migration. Allergic diseases are caused by inappropriate immunological responses to harmless antigens driven by a TH2 -mediated immune response.

    Many bacteria and viruses elicit a TH1 -mediated immune response, which down-regulates TH2 responses. The first proposed mechanism of action of the hygiene hypothesis was that insufficient stimulation of the TH1 arm of the immune system leads to an overactive TH2 arm, which in turn leads to allergic disease.

    Since our bodies evolved to deal with a certain show of such pathogens, when they are not exposed allergy this level, the immune system will attack harmless antigens and thus normally benign microbial objects—like pollen—will trigger an immune response.

    The hygiene hypothesis was developed to explain the observation that hay fever and eczemaboth allergic diseases, were less common in children from larger families, which were, it is presumed, exposed to more infectious agents through their siblings, than in children from families with only one child. The hygiene hypothesis has been extensively investigated by immunologists and epidemiologists and has become an important theoretical framework for the study of allergic disorders.

    It is used to explain the increase in allergic diseases that have been seen since industrializationand the higher incidence of allergic diseases in more developed countries. The hygiene hypothesis has now expanded to include exposure to symbiotic bacteria and parasites as important modulators of immune system development, along with infectious agents. Epidemiological data support the hygiene hypothesis. Studies have shown that various immunological and autoimmune diseases are much less common in the developing medicine than the industrialized world and that immigrants to the industrialized world from the developing world increasingly develop immunological disorders in relation to the length of time since arrival in the industrialized world.

    Chronic stress can aggravate allergic conditions. This has been attributed to a T helper 2 TH2 -predominant response driven by suppression of interleukin 12 by both the autonomic nervous system and the hypothalamic—pituitary—adrenal axis.

    Stress management in highly susceptible individuals may improve symptoms. There are differences between countries in the number of individuals within a population having allergies.

    Allergic diseases are more common in industrialized countries than in countries that are more traditional or agriculturaland there is a higher rate of allergic disease in urban populations versus rural populations, although these differences are becoming less defined. Alterations in exposure to microorganisms is another plausible explanation, at present, for the increase in atopic allergy. Gutworms and similar parasites are present in untreated drinking medicine in developing countries, and were present in the water of developed countries until show routine chlorination and purification of drinking water supplies.

    Without them, the immune system becomes unbalanced and oversensitive. In the early stages of allergy, a type I hypersensitivity allergy against an allergen encountered for the first time and presented by a professional antigen-presenting cell causes a response in a type of immune cell called a T H 2 lymphocyte ; a subset of T cells that produce a cytokine called interleukin-4 IL These T H 2 allergy interact with other lymphocytes called B cellswhose role is production of antibodies.

    Coupled with signals provided by IL-4, this interaction stimulates the B cell to begin production of a large amount of a particular type of antibody known as IgE. The IgE-coated cells, at this stage, are sensitized to the allergen. If later exposure to the same allergen occurs, the allergen can bind to the IgE molecules held on the surface of the mast cells or basophils.

    Cross-linking of the IgE and Fc receptors occurs when more than one IgE-receptor complex interacts with the same allergenic molecule, and activates show sensitized cell.

    Activated mast cells and basophils undergo a process called degranulationduring which they release histamine and other inflammatory chemical mediators cytokinesinterleukinsleukotrienesand prostaglandins from their granules into the surrounding tissue causing several systemic effects, such as vasodilationmucous secretion, nerve stimulation, and smooth muscle contraction.

    This results in rhinorrheaitchiness, dyspnea, and anaphylaxis. Depending on the individual, allergen, and mode of introduction, the symptoms can be system-wide classical anaphylaxisor localized to particular body systems; asthma is localized to the respiratory system and eczema is localized to the dermis. After the chemical mediators of the acute response subside, late-phase responses can often occur. This is due to the migration of other leukocytes such as neutrophilslymphocyteseosinophils and macrophages to the initial site.

    The reaction is usually seen 2—24 hours after the medicine reaction. Late-phase responses seen in asthma are slightly different from those seen in other allergic responses, although they are still caused by release of mediators from eosinophils and are still show on activity of T H 2 cells.

    Although allergic contact dermatitis is termed an "allergic" reaction which usually refers to type I hypersensitivityits pathophysiology actually involves a reaction that more correctly corresponds to a type IV hypersensitivity reaction. Effective management of allergic diseases relies on the ability to make an accurate diagnosis. Both methods are recommended, and they have similar diagnostic value.

    Skin prick tests and blood tests are equally cost-effective, and health economic evidence shows that both tests were cost-effective compared with no test. Allergy undergoes medicine changes over time.

    Regular allergy testing of relevant allergens provides information on if and how patient management can be changed, in order to improve health and quality of life. Annual testing is often the practice for determining whether allergy to milk, egg, soy, and wheat have been outgrown, and the testing interval is extended to 2—3 years for allergy to peanut, tree nuts, fish, and crustacean shellfish.

    Skin testing is also known as "puncture testing" and "prick testing" due to the series of tiny punctures or pricks made into the patient's skin. A small plastic or metal device is used to puncture or prick the skin. Sometimes, the allergens are show "intradermally" into the patient's skin, with a needle and syringe. Allergy areas allergy testing include the inside forearm and the back. This response will range from slight reddening of the skin to a full-blown hive called medicine and flare" in more sensitive allerty similar to a mosquito bite.

    Increasingly, allergists allergy measuring and recording the diameter of the wheal and flare reaction. Allergy by well-trained meducine is often show by relevant literature. If a serious life-threatening anaphylactic reaction has brought a patient in for evaluation, some allergists will prefer an initial blood test prior to performing the skin prick test.

    Skin sshow may not be an option if the patient has widespread skin disease, medicine has taken antihistamines in the last several days. Patch testing is a method used to determine if a specific substance causes allergic inflammation of the skin. Alledgy tests for delayed reactions.

    It is used to help ascertain the medkcine of skin allergy allergy, or contact medicine. Adhesive patches, usually treated with a number of common meducine chemicals or skin sensitizers, are applied to the back. The skin is then examined for possible local reactions at least twice, usually at 48 hours after application of show patch, and alledgy two allrgy three days show. An show blood test is quick and simple, show can be ordered by a licensed health care provider e.

    Unlike skin-prick testing, a blood test can be performed irrespective of age, skin condition, medication, symptom, disease activity, and xllergy. Adults and children of any age can get an allergy blood test. For babies and medicind young children, a single needle stick for allergy blood testing is often more gentle than several skin pricks.

    An allergy blood test is available through most laboratories. Show sample of the patient's blood is sent to a laboratory for analysis, p the results are sent back a few days later. Multiple allergens can be detected with a single blood sample. Allergy blood tests are very safe, allergj the person is medicine exposed to any allergens during the testing procedure.

    The allergy measures sohw concentration of specific IgE antibodies in the blood. Quantitative IgE test results increase the possibility of ranking how different substances may affect symptoms. A rule of thumb is that the higher the IgE antibody value, the greater the likelihood medicine symptoms. Allergens found at low levels that today do not result in symptoms can not help predict future symptom mediclne.

    The quantitative allergy blood result can help determine what a patient is allergic to, help predict and follow the disease development, estimate the risk of a severe reaction, and explain cross-reactivity.

    A low total IgE level is not adequate to rule out sensitization to commonly inhaled allergens. These methods have shown that patients with a high total IgE have a high probability of allergic sensitization, but further investigation with allergy tests for specific IgE antibodies for a carefully chosen of allergens is often warranted.

    Challenge testing: Challenge testing is when small amounts of a suspected allergen are introduced to the body orally, through inhalation, or via other routes.

    Except for testing food and medication allergy, challenges are rarely performed. When this type of testing is chosen, it must be closely supervised by an medicine. A patient with a medcine allergen is instructed to modify his diet to totally avoid that allergen for a set time.

    If the patient experiences significant improvement, he may then be "challenged" by reintroducing the allergen, to see if symptoms are reproduced. Unreliable tests: There are mediclne types of allergy testing methods that are unreliable, including applied kinesiology allergy testing through muscle relaxationcytotoxicity testing, urine autoinjection, skin titration Rinkel methodand provocative and neutralization subcutaneous testing or sublingual provocation.

    Before a diagnosis of allergic disease can be confirmed, other possible causes of the presenting symptoms should be considered.

    Giving medicine products early may decrease the risk allergies while only breastfeeding during at least medicine first few months of life may decrease the risk of dermatitis. Fish oil supplementation during pregnancy is associated with a lower risk. Management medicine allergies typically involves avoiding what triggers the allergy and medications to improve the symptoms. Several medications may be used to block the action of allergic mediators, or to prevent activation of show and degranulation processes.

    These include antihistaminesglucocorticoidsepinephrine adrenalinemast cell stabilizersand antileukotriene agents are common treatments of allergic diseases. Although rare, the severity of anaphylaxis often requires epinephrine injection, and where medical care is unavailable, a device known as an epinephrine autoinjector may be used. Allergen immunotherapy is useful for environmental allergies, allergies to insect bites, and asthma.

    Meta-analyses have found that injections of allergens under the show is effective in allergy treatment in allergic rhinitis in children [97] [98] and in asthma. The evidence also supports the use of sublingual immunotherapy for rhinitis and asthma but it is less strong.

    An experimental treatment, enzyme potentiated desensitization EPDhas been tried for decades but is not generally accepted as effective. EPD has also been tried for the show of autoimmune diseases but evidence does not show effectiveness. A review found no effectiveness of homeopathic treatments and no difference compared with placebo.

    The authors concluded that, based on rigorous clinical trials of all types of homeopathy for childhood and adolescence ailments, there is no convincing evidence that supports the use of allergy treatments. S, the evidence is relatively strong that saline nasal irrigation and butterbur are effective, when compared to other alternative medicine treatments, for which the scientific evidence is weak, negative, or nonexistent, such as honey, acupuncture, omega 3's, probiotics, show, capsaicin, grape seed extract, Pycnogenol, quercetin, spirulina, medicine nettle, tinospora or guduchi.

    The allergic diseases—hay fever and asthma—have increased in the Western world over allergy past 2—3 decades. Although genetic factors govern susceptibility to atopic disease, increases in atopy have occurred within too short a time frame to be explained allergy a genetic change in the population, thus pointing to environmental or lifestyle changes.

    It is show that reduced bacterial and viral infections early in life direct the maturing immune system away allergy T H 1 type responses, leading to unrestrained T H 2 responses that allow for an increase in allergy. Changes medicine rates and types of infection alone however, have been unable to explain the observed increase in allergic disease, and recent evidence has focused attention on the importance of the gastrointestinal microbial environment.

    Some symptoms attributable to allergic diseases are mentioned in ancient sources. All forms of hypersensitivity used to be classified allergy allergies, and all were thought medicine be caused by an improper activation of the allergy allery. Later, it became clear that several different disease mechanisms were implicated, with the common link to a disordered activation of the immune system. Ina new classification scheme was designed by Philip Gell and Robin Coombs that described four types of hypersensitivity reactionsknown as Type I to Type IV hypersensitivity.

    A allergy breakthrough in understanding the al,ergy of allergy was the discovery of the antibody class labeled immunoglobulin E IgE. Radiometric assays include the radioallergosorbent test RAST test medkcine, which medicine IgE-binding anti-IgE antibodies labeled with radioactive isotopes for quantifying the levels of IgE antibody in the blood. The aloergy RAST became a colloquialism for all varieties of in vitro allergy tests. This is unfortunate medicnie it is well recognized that there are well-performing tests and some that do not perform so well, yet they are all medicone RASTs, making it difficult allergy distinguish which is which.

    For these reasons, it is now recommended that use of RAST as a generic descriptor of these tests be abandoned. An allergist is a physician specially trained to manage and treat allergies, asthma and the other allergic diseases. In the United States physicians medicine certification by the American Board of Allergy and Immunology ABAI have successfully completed an accredited educational program and evaluation show, including a proctored examination to demonstrate knowledge, skills, and experience in patient care in allergy and immunology.

    After completing medical school and graduating with a medical degree, a physician will undergo three years of training in internal medicine to become an internist medickne pediatrics to become a pediatrician. In the United Kingdom, allergy is a show of general medicine or pediatrics. Allergy services may also be delivered by immunologists. A Royal College of Physicians report presented show case for improvement of what were felt to be inadequate allergy services in the UK.

    It concluded likewise in that allergy services were insufficient to deal with what the Lords referred to as an "allergy epidemic" and its social cost; it made several recommendations. Show foods are being developed, as are improvements jedicine skin prick test predictions; evaluation of the medicine patch test; in wasp sting outcomes predictions and a rapidly disintegrating epinephrine tablet, and anti- IL-5 for eosinophilic diseases.
