Allergies - Peanut allergy kids


Peanut allergy among children is an abnormal response of the body, mediated by the immune system. In case of an allergy to peanuts, the immune system identifies certain foods as harmful and cause an allergic reaction when their ingestion.
The immune response to the interaction with substances reacting interpreted by the body as NOT - SEL, resulting in humoral and cellular immunity, also called immune reaction.

The immune response depends on: the thymus and functioning and transformation of stem cells and B lymphocytes T.

These lymphocytes contribute to the production of antibodies, cellular immunity and immunological memory. The most severe reaction is anaphylaxis (ANA). ANA affects many body systems and can lead to exitus (death). ANA (severe allergic reaction) usually occurs within minutes or an hour after ingestion and can reappear an hour or two later. Common causes of ANA are: peanuts, nuts and seafood. Peanuts trigger a reaction ANA to children more often than other foods.

Food allergies are more common in children than in adults, in special peanut allergy. A percentage between 6% and 8% in the case of children, but only 2% of adults have such allergies. 
Food allergies are more common in children than in adults. A percentage between 6% and 8% in the case of children, but only 2% of adults have such allergies. Food allergies occur mainly in people with atopic response of the body. They have an inherited tendency to develop allergic reactions. People with atopic response are predisposed to make asthma, allergies and a skin affection, called atopic dermatitis.
Allergies occur when the immune system reacts abnormally to substances contained in food intake, causing an allergic response.  Allergies are more common in young children than in adults. This may be due, immune and digestive system of children who are not are not fully developed.
Peanuts, it causes the majority of reactions allergy in children. Some babies are so sensitive that if these foods, is consumed by the mother, breastfeeding baby produces a reaction. Most children heal from allergies to milk, wheat, eggs and soy between the ages of 3 and 5 years. Children rarely heal from peanuts allergy.
Peanuts produce the most allergic reactions in adolescents and adults.
If a person is extremely sensitive to certain foods, she may develop an allergic reaction, the mere presence of food around the person.
If travelling by plane and there are passengers who eat peanuts, be sure children can trigger the peanut allergy symptoms.
Because peanuts are present in so many dishes, peanut allergy has increased in the US in the last two decades and is now a major cause of severe reactions of food allergy. Peanut allergy lasts a lifetime and tends to worsen over time and children are most affected because a wide range of chocolates, candies and cereals for children that contain at least traces of peanuts.
The risk that children develop an allergy to peanuts or any other food allergy is bigger in the case in which there is a family history of allergy. Food allergies are most commonly found in people who are atopic, that have an inherited tendency to make asthma, eczema and various allergic reactions. If both parents are allergic, probability and baby, make allergies is 75%.
 The risk of developing a life-threatening allergic reaction is higher if:
  • The patient suffers from asthma;
  • Symptoms due to allergy trigger minutes after ingesting the food.
If a person or child has a severe food allergy, should always carry a first aid kit, in case of allergy and know how to use it. The person or child should wear a bracelet permanent record of the disease. Be trained and prepare for handling, prompt and appropriate a severe allergic reaction to be able to decrease the risk of exitus.


Symptoms of food allergies can affect many body parts, including:
  • The digestive system: cramps, nausea, vomiting, diarrhea, pruritus (itching) in the mouth and throat and rectal (rectal bleeding, rare in adults). Symptoms occur more frequently in children than in adults.
  • Skin: hives, swelling, itching, redness and atopic dermatitis. Skin reactions are more common in children.
  • Respiratory system:  cough; wheezing (whistling is heard on expiration and which have the cause airway obstruction, especially the bronchi); itchy nose, runny nose abundant and consistent; sneezing and breathing difficulties.
Children usually have the same symptoms as adults. However, sometimes the only symptoms are: crying loud (due to colic), vomiting and blood in stool, diarrhea and constipation, and growth retardation.
The severity of symptoms varies from moderate to life-threatening and can occur in a range from minutes to days after ingestion of a food. The most severe reaction is anaphylaxis usually occurs within minutes or an hour after ingestion and can reappear an hour or two later. Common causes of ANA are: peanuts, nuts and seafood;
Peanuts trigger a reaction to children more often than other foods.
Severe symptoms can appear if children, have other allergies, such as allergies to pollen or mold. Smoking, stress and cold can worsen symptoms.
Emergency medical services should be contacted immediately if the child or person has suffered a severe allergic reaction in the past, caused by the same food with similar symptoms. If first aid kit recommended by the doctor, in case of severe allergic reactions it is available, should make an injection of epinephrine before calling for help. If it be possible, it would be preferable for someone to call for help, while the affected person, it makes the injection of epinephrine.
Because symptoms may recur even if the injection was made, the person should go to the emergency room every time she has an allergic reaction, even if it feels better. The observation period is 4 to 8 hours, from suspected reaction.


Emergency services should be called immediately if it appears one of the following allergy signs:
  • Edema (swelling) throat or tongue, appeared quickly;
  • Shortness of breath, wheezing or coughing deep;
  • Facial pallor or cyanosis (blue coloration of the skin, is a lack of oxygen to tissues) lips or earlobes;
  • Signs of shock;
  • Dizziness or fainting;
  • Restlessness, sensation of imminent death;
  • Cold and clammy skin, or even profuse sweating;
  • Weakness, thirst, nausea, vomiting;
  • Fainting.
If symptoms worsen, the doctor should be contacted.


Optimal treatment for allergies to peanuts, as in the case of others about food allergies is to avoid foods that underlie those producing allergies. When this is not possible, it may try medications such as antihistamines for mild allergies, and medicines for allergies first aid kit in case of severe reactions.
It is important to give special attention to children who are food allergies. A child that makes severe allergies may develop a life-threatening anaphylactic reaction, even trace amounts of peanuts. The child should wear a bracelet at all times for monitoring the disease and a first aid kit in case of severe allergies.
Children can have mild symptoms in the first few minutes after ingesting peanuts (allergen), but may develop severe symptoms in 10 to 60 minutes. They should be kept under observation in hospital for at least 4 hours after the occurrence of allergic reactions.
If the allergic reaction is severe, initial treatment may be given in the emergency room or by medical emergency epinephrine injection to prevent the release of histamine and additional respiratory muscles to relax. Children who are at high risk of doing severe allergic reactions should have first aid kits at school, kindergarten, but at home. Parents must ensure that the school principal, teachers and friends are informed about child allergy which he has.


Among the new options for the treatment of food allergies include:
  • Injection of anti-immunoglobulin E with these antibodies are able to reduce allergic reactions;
  • Immunotherapy SCIT (allergy injections or desensitization therapy) which help the body become less sensitive to a substance that is allergic;
  • Vaccination with a specific genetic substance of a particular food allergen.


Mothers, breastfeeding should eliminate from the diet, peanuts because the fetus can develop an allergy to peanuts before birth, creating complications or pregnancy while the child may develop allergy to peanuts or other derivatives. Solid foods should not be placed in the infant's diet for 6 months before. Peanuts and peanut products containing or has derived there what should not be placed in the diets of children before age 3 years. These measures may help reduce the risk of food allergies. Pregnant women should not exclude those foods from the diet, except peanuts.
