What microbe causes Peanut Allergy?

Allergies are not a disease. They are not caused by bacteria, what happens during an allergy is that your body over-reacts to a small amount of protein from something, also known as an allergen. This then makes the body ill, often putting the body through 'shock' also known as anaphylaxis.


Also known as hypersensitivity?

Allergen


What is the treatment for anaphylaxis?

anaphylaxis is treated with injection of adrenaline, also known as epinephrine. People who are prone to anaphylaxis because of food or insect allergies often carry an "Epi-pen" containing adrenaline in a hypodermic needle.


How does an allergic reaction feel?

Allergic reactions can be mild, like sneezing or coughing. They can also be severe, such as anaphylaxis. Anaphylaxis is characterized by difficulty breathing or swallowing, swelling of the lips, tongue, or other parts of the body, dizziness or loss of consciousness. This usually occurs within minutes after contact with the allergen but can take up to 4 hours. These kind of allergic reactions are rare and can be treated successfully if treated correctly.If the allergen is breathed in, such as flower pollen the reaction usually occurs in the nose, and eyes. If the allergen is eaten, such as peanuts, then the reaction is usually in the mouth, tongue, throat and/or the intestinal tract. If the allergen touches the skin, such as poison ivy, the allergic reaction is usually swelling or itching.Histamines, along with other similar chemicals, are known as mediators and are generally responsible for many of those physiological reactions we associate with an allergic reaction such as itching and itchy eyes, rashes, hives, sneezing, nausea, and a runny nose. They can also induce much more serious reactions including difficulty breathing (constriction of the airway), a dilation of blood vessels, and of course, anaphylactic shock.

What are the basic uses of epinephrine?

The epi-pen was created to delay anaphylactic shock among people with severe allergies. Symptoms of anaphylactic shock, also known as anaphylaxis, include the severe constriction of blood vessels and bronchial tubes due to an extreme allergic reaction. Most cases of anaphylaxis are fatal if not treated before total constriction of bronchial tubes (usually within 10-20min). Immediate hospitalization is required to bring histamine levels back to normal. The epi-pen is designed to create immediate production of the hormone adrenaline which prevents the blood vessels and bronchial tubes from completely constricting. Allowing the victim time to get to the hospital. As soon as the person with the allergies start complaining of throat closure or they come in contact with a known life-threatening allergen, The epi-pen should be injected into the person's thigh! It is essential to inject the epi-pen as quickly as possible, before anaphylaxis can set in. Quick recognition and injection can save lives. Note: Anaphylaxis results in vasodilatation (the opposite of constriction) which leads to a drop in blood pressure since there is not enough blood volume in the body to fill all the blood vessels to capacity if they are all dilated and still maintain a blood pressure. This is why people in anaphylactic shock often have pink, well-perfused skin rather then the usual pallor associated with shock of other causes. An Epi-pen contains adrenaline (which is another name for epinephrine) which can reverse bronchconstriction and vasodilatation directly and not through the facilitation of epinephrine production. As noted above, the epi pen should be administered as soon as the condition is suspected because the combination of shock and inadequate ventilation of the lungs can be rapidly fatal and becomes more difficult to reverse as time goes on. The design of the epi-pen is such that it can be administered by the victim themselves if they are conscious enough and no help is available, and should be in conjunction with a call for EMS in case further intervention becomes necessary.
