Oral Allergy Syndrome
Pollen-related oral allergy syndrome, also called en pollen-food syndrome ur, is the most common form of food allergy in adults. It is due to the similarity between respiratory allergens and food allergens. Oral allergy syndrome is more common in birch pollen susceptible patients. Patients with latex sensitivity may experience severe systemic reactions due to consumption of bananas, avocados, chestnuts and kiwis.
Those with pollen allergy may develop itching, redness and swelling in the mouth and throat after consumption of raw vegetables and fruits.
Clinical Findings;
Oral allergy syndrome often develops after oral ingestion of various fruits, nuts, and / or vegetables in adult individuals with pollen-sensitive allergic rhinitis. Symptoms of oral allergy syndrome are IgE-mediated reactions due to cross-reactivity between inhaled and plant-derived food allergens, limited to the oral mucosa, lips, tongue and throat region, typically not leading to systemic reactions.
Symptoms usually begin within 5-15 minutes after raw food consumption. Itching, lethargy and even mild swelling are typical symptoms of the lips, tongue, palate, ears and throat. Sometimes red spots and vesicles may develop inside the mouth. Most of the time it resolves spontaneously within 30 minutes, but rarely progresses to a systemic reaction.
Oral allergy syndrome often occurs with the ingestion of apples, nuts, celery and carrots.
Diagnosis;
Based on the history, skin prick tests are performed on allergens that have the potential to cross-react with suspicious foods. It can then be diagnosed by ik prik-to-prik ile tests with fresh forms (raw / cooked-processed) of suspicious nutrients.
In case of uncertainty in the patient's history and skin test results, allergen-specific IgE can be measured. However, component-based diagnostic approach is more appropriate for a more accurate diagnosis. Food-specific IgG or IgG4 measurement is not clinically useful in food allergy.
Treatment
In oral allergy syndrome, education, food avoidance and symptoms alleviation are the mainstay of treatment.
Food avoidance should only be recommended based on the results of the food challenge test in the presence of appropriate clinical history. Individuals do not need to be included in the elimination diet because they are sensitive to pollen only.
Patients with oral allergy syndrome often consume well-cooked and preserved foods. However, food such as celery, peanuts and strawberries can cause symptoms after cooking.
If the reaction occurs unintentionally, the patient should remain calm, rinse his mouth with water and rest. Symptoms resolve with antihistamines in a short time. Rarely, patients with severe symptoms or anaphylaxis should carry adrenaline auto-injectors.
Immunotherapy (pollen) for pollen also shows that symptoms associated with oral allergy syndrome are reduced.
