Allergyare a common allergic symptomSymptoms, itchy rash, swelling,Types,Causesand environmental factorsBased on symptoms,PreventionEarly exposure to potential allergensTreatmentAvoiding known allergens, medications,Medication,FrequencyCommonAllergies, also known as allergic diseases, are a number of conditions caused by of the to typically harmless substances in the environment. These diseases include,. Symptoms may include, an itchy rash, a, or swelling. And are separate conditions.Common include and certain food. Metals and other substances may also cause problems. Food, and medications are common causes of severe reactions.

Their development is due to both genetic and environmental factors. The underlying mechanism involves (IgE), part of the body's immune system, binding to an allergen and then to on or where it triggers the release of inflammatory chemicals such as. Diagnosis is typically based on a person's.

Further testing of the or blood may be useful in certain cases. Positive tests, however, may not mean there is a significant allergy to the substance in question.Early exposure to potential allergens may be protective. Treatments for allergies include avoiding known allergens and the use of medications such as. In severe reactions injectable (epinephrine) is recommended., which gradually exposes people to larger and larger amounts of allergen, is useful for some types of allergies such as hay fever and reactions to insect bites.

Its use in food allergies is unclear.Allergies are common. In the developed world, about 20% of people are affected by, about 6% of people have at least one food allergy, and about 20% have at some point in time.

Depending on the country about 1–18% of people have asthma. Anaphylaxis occurs in between 0.05–2% of people. Rates of many allergic diseases appear to be increasing. The word 'allergy' was first used by in 1906. Contents.Signs and symptoms Affected organCommon signs and symptomsSwelling of the nasal runny nose,AllergicRedness and of the (allergic conjunctivitis, watery)Sneezing, coughing, and, sometimes outright attacks of, in severe cases the airway constricts due to swelling known asFeeling of fullness, possibly pain, and impaired hearing due to the lack of drainage., such as and,Many allergens such as dust or pollen are airborne particles.

In these cases, symptoms arise in areas in contact with air, such as eyes, nose, and lungs. For instance, also known as hay fever, causes irritation of the nose, sneezing, itching, and redness of the eyes. Inhaled allergens can also lead to increased production of in the, coughing, and wheezing.Aside from these ambient allergens, allergic reactions can result from, and reactions to like and such as. Symptoms of food allergy include, vomiting, skin,. Food allergies rarely cause (asthmatic) reactions,. Insect stings, food, and certain medicines may produce a systemic allergic response that is also called; multiple organ systems can be affected, including the, the, and the.

Depending on the rate of severity, anaphylaxis can include skin reactions, bronchoconstriction,. This type of reaction can be triggered suddenly, or the onset can be delayed. The nature of is such that the reaction can seem to be subsiding, but may recur throughout a period of time.

Skin Substances that come into contact with the skin, such as, are also common causes of allergic reactions, known as or eczema. Skin allergies frequently cause rashes, or swelling and inflammation within the skin, in what is known as a ' and flare' reaction characteristic of hives and angioedema.With insect stings a large local reaction may occur (an area of skin redness greater than 10 cm in size). It can last one to two days. This reaction may also occur after.

Cause Risk factors for allergy can be placed in two general categories, namely and factors. Host factors include, and age, with heredity being by far the most significant. 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 during early childhood, environmental, allergen levels, and changes. Main article:A wide variety of foods can cause allergic reactions, but 90% of allergic responses to foods are caused by cow's,. Other, affecting less than 1 person per 10,000 population, may be considered 'rare'.

The use of hydrolysed milk versus standard milk baby formula does not appear to change the risk.The most common food allergy in the US population is a sensitivity to. Although peanut allergies are notorious for their severity, peanut allergies are not the most common food allergy in adults or children. Severe or life-threatening reactions may be triggered by other allergens, and are more common when combined with asthma.Rates of allergies differ between adults and children. Allergies can sometimes be outgrown by children. Egg allergies affect one to two percent of children but are outgrown by about two-thirds of children by the age of 5. The sensitivity is usually to proteins in the white, rather than the.Milk-protein allergies are most common in children.

Approximately 60% of milk-protein reactions are -mediated, with the remaining usually attributable to. Some people are unable to tolerate milk from goats or sheep as well as from cows, and many are also unable to tolerate products such as cheese.

Roughly 10% of children with a milk allergy will have a reaction to. Beef contains a small amount of protein that is present in cow's milk., a common reaction to milk, is not a form of allergy at all, but rather due to the absence of an in the.Those with allergies may be allergic to one or to many tree nuts, including pecans, pistachios, pine nuts, and walnuts. Also, including and, contain oils in which protein is present, which may elicit an allergic reaction.Allergens can be transferred from one food to another through; 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 800 surgical patients (0.125 percent) reported latex sensitivity, although the sensitivity among healthcare workers is higher, between seven and ten percent. Researchers attribute this higher level to the exposure of healthcare workers to areas with significant airborne latex allergens, such as operating rooms, intensive-care units, and dental suites. These latex-rich environments may sensitize healthcare workers who regularly inhale allergenic proteins.The most prevalent response to latex is an allergic contact dermatitis, a delayed hypersensitive reaction appearing as dry, crusted lesions. This reaction usually lasts 48–96 hours. Sweating or rubbing the area under the glove aggravates the lesions, possibly leading to ulcerations.

Reactions occur most often in sensitive patients who have been exposed to a surgeon's latex gloves during abdominal surgery, but other exposures, such as dental procedures, can also produce systemic reactions.Latex and banana sensitivity may cross-react. Furthermore, those with latex allergy may also have sensitivities to avocado, kiwifruit, and chestnut. These people often have itching and local. 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 with some other plant proteins. Medications. Main article:Typically, which generate allergic responses are either stinging insects (, and ) or biting insects (, ).

Stinging insects inject venom into their victims, whilst biting insects normally introduce.Toxins interacting with proteins Another non-food protein reaction, originates after contact with, or., which is not itself a protein, acts as a and chemically reacts with, binds to, and changes the shape of on exposed skin cells. The immune system does not recognize the affected cells as normal parts of the body, causing a -mediated.

Of these poisonous plants, sumac is the most virulent. The resulting dermatological response to the reaction between urushiol and membrane proteins includes redness, swelling, and streaking.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.0050 milligrams (7.7 ×10 −5 gr) of purified urushiol, but some people are so sensitive that it takes only a molecular trace on the skin to initiate an allergic reaction. Genetics Allergic diseases are strongly: are likely to have the same allergic diseases about 70% of the time; the same allergy occurs about 40% of the time in. Allergic parents are more likely to have allergic children, and those children's allergies are likely to be more severe than those in children of non-allergic parents. Some allergies, however, are not consistent along; parents who are allergic to may have children who are allergic to. It seems that the likelihood of developing allergies is and related to an irregularity in the immune system, but the specific is not.The risk of allergic and the development of allergies varies with age, with young children most at risk. Several studies have shown that IgE levels are highest in childhood and fall rapidly between the ages of 10 and 30 years.

The peak prevalence of hay fever is highest in children and young adults and the incidence of asthma is highest in children under 10.Overall, boys have a higher risk of developing allergies than girls, although for some diseases, namely asthma in young adults, females are more likely to be affected. These differences between the sexes tend to decrease in adulthood.may play a role in some allergies; however, racial factors have been difficult to separate from environmental influences and changes due to. It has been suggested that different are responsible for asthma, to be specific, in people of, and African origins. Hygiene hypothesis. Main article:Allergic diseases are caused by inappropriate immunological responses to harmless driven by a -mediated immune response. Many and elicit a -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. In other words, individuals living in too sterile an environment are not exposed to enough pathogens to keep the immune system busy. Since our bodies evolved to deal with a certain level of such pathogens, when they are not exposed to 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 and, both 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 and 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, and 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 world 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. Longitudinal studies in the third world demonstrate an increase in immunological disorders as a country grows more affluent and, it is presumed, cleaner.

The use of antibiotics in the first year of life has been linked to asthma and other allergic diseases. The use of antibacterial cleaning products has also been associated with higher incidence of, as has birth by rather than vaginal birth. Stress Chronic can aggravate allergic conditions.

This has been attributed to a T helper 2 (TH2)-predominant response driven by suppression of by both the and the. Bow wow relationship goals mp3 download. Stress management in highly susceptible individuals may improve symptoms. Other environmental factors There are differences between countries in the number of individuals within a population having allergies. Allergic diseases are more common in countries than in countries that are more traditional or, and there is a higher rate of allergic disease in populations versus populations, although these differences are becoming less defined.Alterations in exposure to is another plausible explanation, at present, for the increase in.

Endotoxin exposure reduces release of inflammatory such as, and from white blood cells that circulate in the. Certain microbe-sensing, known as, found on the surface of cells in the body are also thought to be involved in these processes.Gutworms and similar parasites are present in untreated drinking water in developing countries, and were present in the water of developed countries until the routine and purification of drinking water supplies. Recent research has shown that some common, such as (e.g., ), secrete chemicals into the gut wall (and, hence, the bloodstream) that the immune system and prevent the body from attacking the parasite. This gives rise to a new slant on the hygiene hypothesis theory—that of humans and parasites has led to an immune system that functions correctly only in the presence of the parasites.

Without them, the immune system becomes unbalanced and oversensitive. In particular, research suggests that allergies may coincide with the delayed establishment of in.

However, the research to support this theory is conflicting, with some studies performed in China and showing an increase in allergy in people infected with intestinal worms. Clinical trials have been initiated to test the effectiveness of certain worms in treating some allergies. It may be that the term 'parasite' could turn out to be inappropriate, and in fact a hitherto unsuspected is at work. For more information on this topic, see.Pathophysiology. Degranulation process in allergy.

Second exposure to allergen. 1 – antigen; 2 – IgE antibody; 3 – FcεRI receptor; 4 – preformed mediators (histamine, proteases, chemokines, heparin); 5 –; 6 –; 7 – newly formed mediators (prostaglandins, leukotrienes, thromboxanes, )In the early stages of allergy, a type I hypersensitivity reaction against an allergen encountered for the first time and presented by a professional causes a response in a type of immune cell called a; a subset of that produce a called (IL-4). These T H2 cells interact with other called, whose 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.

Secreted IgE circulates in the blood and binds to an IgE-specific receptor (a kind of called ) on the surface of other kinds of immune cells called and, which are both involved in the acute inflammatory response. 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 the sensitized cell. Activated mast cells and basophils undergo a process called, during which they release and other inflammatory chemical mediators (, and ) from their into the surrounding tissue causing several systemic effects, such as, secretion, stimulation, and contraction.

This results in, itchiness, dyspnea,. Depending on the individual, allergen, and mode of introduction, the symptoms can be system-wide (classical anaphylaxis), or localized to particular body systems; asthma is localized to the respiratory system and eczema is localized to the. Late-phase response After the chemical mediators of the acute response subside, late-phase responses can often occur. This is due to the migration of other such as, and to the initial site. The reaction is usually seen 2–24 hours after the original reaction. Cytokines from mast cells may play a role in the persistence of long-term effects. Late-phase responses seen in are slightly different from those seen in other allergic responses, although they are still caused by release of mediators from eosinophils and are still dependent on activity of T H2 cells.

Allergic contact dermatitis Although is termed an 'allergic' reaction (which usually refers to type I hypersensitivity), its pathophysiology actually involves a reaction that more correctly corresponds to a reaction. In type IV hypersensitivity, there is activation of certain types of (CD8+) that destroy target cells on contact, as well as activated that produce.Diagnosis. An allergy testing machine being operated in the diagnostic immunology labEffective management of allergic diseases relies on the ability to make an accurate diagnosis. Allergy testing can help confirm or rule out allergies. Correct diagnosis, counseling, and avoidance advice based on valid allergy test results reduces the incidence of symptoms and need for medications, and improves quality of life.

To assess the presence of allergen-specific IgE antibodies, two different methods can be used: a skin prick test, or an allergy. 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. Also, early and more accurate diagnoses save cost due to reduced consultations, referrals to secondary care, misdiagnosis, and emergency admissions.Allergy undergoes dynamic 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.

Results of follow-up testing can guide decision-making regarding whether and when it is safe to introduce or re-introduce allergenic food into the diet. Skin prick testing. Skin testing on backSkin 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. Small amounts of suspected allergens and/or their ( e.g., pollen, grass, mite proteins, peanut extract) are introduced to sites on the skin marked with pen or dye (the ink/dye should be carefully selected, lest it cause an allergic response itself). A small plastic or metal device is used to puncture or prick the skin. Sometimes, the allergens are injected 'intradermally' into the patient's skin, with a needle and syringe.

Common areas for testing include the inside forearm and the back.If the patient is allergic to the substance, then a visible inflammatory reaction will usually occur within 30 minutes. This response will range from slight reddening of the skin to a full-blown (called 'wheal and flare') in more sensitive patients similar to a. Interpretation of the results of the skin prick test is normally done by allergists on a scale of severity, with +/− meaning borderline reactivity, and 4+ being a large reaction. Increasingly, allergists are measuring and recording the diameter of the wheal and flare reaction.

Interpretation by well-trained allergists is often guided by relevant literature. Some patients may believe they have determined their own allergic sensitivity from observation, but a skin test has been shown to be much better than patient observation to detect allergy.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 tests may not be an option if the patient has widespread skin disease, or has taken in the last several days.Patch testing. Patch testing is a method used to determine if a specific substance causes allergic inflammation of the skin. It tests for delayed reactions. It is used to help ascertain the cause of skin contact allergy,.

Adhesive patches, usually treated with a number of common allergic 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 the patch, and again two or three days later.Blood testing An allergy is quick and simple, and can be ordered by a licensed health care provider ( e.g., an allergy specialist) or general practitioner. Unlike skin-prick testing, a blood test can be performed irrespective of age, skin condition, medication, symptom, disease activity, and pregnancy. Adults and children of any age can get an allergy blood test. For babies and very 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. A sample of the patient's blood is sent to a laboratory for analysis, and 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, since the person is not exposed to any allergens during the testing procedure.The test measures the concentration of specific in the blood. 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 of symptoms. Allergens found at low levels that today do not result in symptoms can not help predict future symptom development. 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.A low total IgE level is not adequate to rule out to commonly inhaled allergens., such as, predictive value calculations, and likelihood ratios have been used to examine the relationship of various testing methods to each other. 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.Laboratory methods to measure specific IgE antibodies for allergy testing include (ELISA, or EIA), (RAST) and fluorescent enzyme (FEIA). Other testing 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 allergies, challenges are rarely performed. When this type of testing is chosen, it must be closely supervised by an.Elimination/challenge tests: This testing method is used most often with foods or medicines. A patient with a suspected 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 other types of allergy testing methods that are unreliable, including (allergy testing through muscle relaxation), testing, urine autoinjection, skin (Rinkel method), and provocative and neutralization (subcutaneous) testing or sublingual provocation. Differential diagnosis Before a diagnosis of allergic disease can be confirmed, other possible causes of the presenting symptoms should be considered., for example, is one of many illnesses that share symptoms with allergic rhinitis, underscoring the need for professional differential diagnosis. Once a diagnosis of, rhinitis, or other allergic disease has been made, there are several methods for discovering the causative agent of that allergy.Prevention. Further information:Giving peanut products early may decrease the risk allergies while only during at least the first few months of life may decrease the risk of.

There is no good evidence that a mother's diet during or breastfeeding affects the risk. Nor is there evidence that delayed introduction of certain foods is useful. Early exposure to potential allergens may actually be protective.Fish oil supplementation during pregnancy is associated with a lower risk. Probiotic supplements during pregnancy or infancy may help to prevent.

Management Management of allergies typically involves avoiding what triggers the allergy and medications to improve the symptoms. May be useful for some types of allergies. Medication Several medications may be used to block the action of allergic mediators, or to prevent activation of cells and processes. These include, (adrenaline), and are common treatments of allergic diseases., and other compounds thought to impair, are also commonly used. Although rare, the severity of often requires injection, and where medical care is unavailable, a device known as an may be used.

Immunotherapy. Anti-allergy immunotherapyAllergen is useful for environmental allergies, allergies to insect bites, and asthma. Its benefit for food allergies is unclear and thus not recommended. Immunotherapy involves exposing people to larger and larger amounts of allergen in an effort to change the immune system's response.Meta-analyses have found that injections of allergens under the skin is effective in the treatment in allergic rhinitis in children and in asthma. The benefits may last for years after treatment is stopped. It is generally safe and effective for allergic rhinitis and, allergic forms of asthma, and stinging insects.The evidence also supports the use of for rhinitis and asthma but it is less strong.

For seasonal allergies the benefit is small. In this form the allergen is given under the tongue and people often prefer it to injections.

Immunotherapy is not recommended as a stand-alone treatment for asthma. Alternative medicine An experimental treatment, (EPD), has been tried for decades but is not generally accepted as effective.

EPD uses dilutions of allergen and an enzyme, to which are supposed to respond by favoring desensitization, or down-regulation, rather than sensitization. EPD has also been tried for the treatment of but evidence does not show effectiveness.A review found no effectiveness of and no difference compared with.
