The fourth patient was sensitised to birch pollen but not to latex reacted with recombinant banana profilin Grob et al. OAS, urticaria and tachycardia Grob et al. The presence of cross-reacting allergens in natural rubber latex and banana has been confirmed by immunoblot inhibition Alenius et al.
Cross-reacting IgE antibodies recognizing latex and fruit allergens papaya, avocado, banana, chestnut, passion fruit, fig, melon, mango, kiwi, pineapple, peach, and tomato were demonstrated by RAST-inhibition tests on latex-allergic patients and a 30 control without clinical syntoms of latex allergy Brehler et al. Moller et al. Chitin recognition protein Pfam PF AF; AAB Banana furits were peeled, freeze-dried, ground and defatted with cold acetone.
The residue was extracted with PBS buffer, centrifuged and dialysed against water. The protein preparation was fractionated by affinity-chromatography on a regenerated chitin column equilibrated with 20 mM Tris-HCl. Elution was performed with 20 mM sodium acetate pH 5. AF; AAK There are only few studies on the stability of profilins most of them on celery profilin.
Compared to other allergens, profilin is a moderately stable protein, more resistant than Bet v 1 homologues but less stable than lipid transfer proteins or corss-reactive carbohydrate deteminants of glycoporein allergens. High IgE cross-reactivity of banana profilin with birch pollen profilin, Bet v 2, and latex profilin, Hev b 8, was demonstrated by immunoblot inhibition as well as EAST inhibition experiments Reindl et al.

Allergy Information: Banana allergy can take two different forms: one associated with allergy to tree pollen, such as birch, and another type associated with latex allergy. People with birch-pollen allergy can develop symptoms either immediately or up to 1 hour after eating fresh banana or a banana-containing food.
Symptoms comprise local reactions in the mouth and throat with itching and inflammation called oral allergy syndrome, OAS. Supplementary information on Banana Allergy Banana is the crescent-shaped edible fruit of any of several species of the musaceous genus Musa, which are tropical and subtropical herbaceous tree-like plants. Symptoms Patients with allergy to banana report adverse reactions immediately after banana consumption, i.
How much is too much? Related foods cross reactivity Banana allergy rarely presents as an isolated disorder, due to cross-reactivity with allergens from other sources. Who, when, how long, and how often? Diagnosis With no doubt, clinical history is the best way to detect banana allergy. Avoidance Patients suspected of being allergic to banana, should completely avoid the ingestion of both fresh bananas and of any banana-containing food, until evaluated.
Mikkola [ ] Prick by prick. Lavaud et al [ ] 22 latex-allergic patients and 22 control subjects with no evidence of allergy to latex or to banana. Delbourg et al [ 42 ] 47 latex allergic patients Beezhold et al [ ] 4 patients allergic to natural rubber latex Mikkola et al. This is not a true allergy but a skin irritation from the acidic fruit.
Wiping the mouth and face immediately after eating can reduce or eliminate symptoms of irritation. A person should always be cautious when introducing new foods to an infant, particularly to common allergens such as peanuts. If a child has eczema or another allergy, the risk of a severe allergic reaction to a food or other substance is greater. Delaying the introduction of these foods increases the risk of food allergies. Parents and guardians should monitor infants and young children for signs of an allergic syndrome called food protein-induced enterocolitis syndrome FPIES.
Children with FPIES develop severe gastrointestinal symptoms, including vomiting and diarrhea 2—3 hours after eating an allergen. Blood allergy tests are unlikely to diagnose the condition. FPIES then usually causes allergies to many foods when these start to be eaten, though dairy and soy are among the most common triggers.
Children with this disorder often need to eat a limited diet, and untreated FPIES can cause severe malnourishment and dehydration. Banana proteins are very similar to proteins found in many other fruits and vegetables. So, if someone has a banana allergy, it is important for them to consider allergy testing to know what foods they can and cannot eat safely.
A cross-reaction to banana is also seen in those who are allergic to ragweed, especially during ragweed pollen season in the late summer and fall. People with a banana allergy are also likely to develop an allergy to latex, which is used in many common products, including hygiene gloves, balloons, and some condoms. Anyone who has concerns should tell a doctor about any history of banana allergies before using latex products and consider testing for a latex allergy.
Many people are still able to eat cooked bananas if they have a banana allergy. This is because the allergen protein disintegrates when the banana is cooked. It may not be necessary to avoid cooked foods containing bananas, but only an allergist can provide someone with accurate, individualized information about the risks.
Banana allergies are often treatable, but not all rashes and signs of irritation are due to allergies. This means that allergy testing can help determine what the right treatment is, as well as rule out other potential health conditions. If you have multiple food sensitivities, your doctor will refer you to an allergy specialist.
This doctor will run a comprehensive test to identify your allergies. People with a banana-latex allergy should avoid bananas and forgo any latex-containing objects. Read labels or ask about an ingredients list before you eat anything, including flavored medication.
People with a banana allergy often have other sensitivities. See your doctor for a comprehensive allergic profile so you know what to avoid, and then stock up on plenty of safe, yummy alternatives. Blue java bananas are a type of banana with a taste and texture reminiscent of vanilla ice cream.

Food sensitivity tests check how your immune system responds to different types of food. Read more to figure out which test is best for you. However, the absorption of latex through broken skin can increase the risk of latex allergy in susceptible people immediate-type latex allergy — in genetically susceptible people, initial exposure to latex prompts the immune system to create antibodies.
On subsequent exposure to latex, the body mounts an immune system response, which includes the release of histamine. This can cause a wide range of sudden reactions including hives, swollen lips and, in severe cases, anaphylaxis. Anaphylaxis, or anaphylactic shock, is an emergency and can be fatal.
People at increased risk of latex allergy Certain people are at increased risk of developing latex allergy including: health care workers such as doctors, nurses and dentists who are frequently exposed to latex through medical equipment like gloves people who have had many operations, particularly from a young age, such as those with spina bifida people who work in latex manufacture people with pre-existing allergies, such as hay fever, asthma and eczema people with allergies to particular foods, including avocado and banana.
Latex allergy and food Around half of all people with latex allergy have allergic reactions when eating particular foods, including avocado, banana, chestnut, kiwifruit, passionfruit, plum, strawberry and tomato.
Diagnosis of latex allergy Latex allergy is diagnosed using a number of tests including: medical history physical examination allergy testing, including skin prick tests and blood tests.
Treatment of latex allergy There is no cure for latex allergy. Suggestions include: Choose synthetic rubber products. You may have to change career if your profession involves unavoidable exposure to latex. Consider alternative forms of contraception to condoms or diaphragms. However, remember that condoms are essential as barriers against sexually transmitted infections. Latex-free condoms are available from pharmacists and other retailers.
Always tell your health care professionals such as doctors and dentists that you are allergic to latex before undergoing any procedure, so they can make sure to have non-latex equipment on hand. Be on the lookout for situations that may expose you to latex — for example, your hairdresser or take-away food handler may wear latex gloves. Avoid foods such as banana or avocado that trigger symptoms. Wear a specially designed medical alert bracelet or pendant to provide information about your allergy in case of emergencies.
If prescribed, always carry an adrenaline epinephrine autoinjector in case you experience anaphylaxis. Make sure that family, friends and co-workers know how to use the adrenaline autoinjector in case you need help.
Irritant dermatitis and potential latex allergy If you have irritant dermatitis, you can reduce your risk of developing latex allergy in a number of ways including: Choose synthetic rubber products if possible.
If you have to wear latex gloves, ask for the non-powdered variety the corn starch in powdered gloves may become airborne and be inhaled, along with particles of latex.
Request that your co-workers also wear non-powdered gloves.
