Diagnosis and Treatment of Allergies: An Overview

Diagnosis of Allergies: Methods and Practices

Diagnosis of Nasal and Ocular Allergies

Nasal and ocular allergies, commonly referred to as allergic rhinoconjunctivitis (ARC), are often diagnosed by general practitioners such as family physicians and pediatricians. According to a survey, 46% of adult patients reported being diagnosed by family practitioners, while 41% of children were diagnosed by pediatricians. In contrast, allergists and otolaryngologists were less frequently involved in initial diagnoses but were more likely to conduct allergy tests, with 94.9% of allergist-diagnosed patients and 62.7% of otolaryngologist-diagnosed patients receiving such tests.

Diagnosis of Food Allergies

Food allergies are diagnosed using a combination of methods, including skin prick tests, allergen-specific serum IgE tests, and oral food challenges. These tests help differentiate between IgE-mediated allergies and other non-immune-mediated adverse food reactions. Accurate diagnosis is crucial as it informs the management and treatment strategies for the patient .

Allergy Testing in Children

Children with persistent, recurrent, or severe symptoms suggestive of allergies should undergo appropriate diagnostic work-ups. Allergy testing in children typically involves a detailed case history and the determination of IgE sensitization through skin prick tests or serum-specific IgE measurements. These tests are essential for identifying allergic triggers and guiding treatment options .

Treatment of Allergies: Approaches and Strategies

Over-the-Counter and Prescription Medications

The majority of patients manage their allergy symptoms with over-the-counter medications, with 75.8% of surveyed patients using such treatments. Prescription medications are also commonly used, with 53.5% of patients reporting their use. These medications help alleviate symptoms but do not address the underlying cause of the allergies.

Allergen Immunotherapy

Allergen immunotherapy is a treatment option primarily provided by allergy specialists. It involves the gradual introduction of allergens to build tolerance and reduce symptoms. This therapy is effective for conditions such as allergic rhinitis, asthma, and stinging insect allergies. The use of immunotherapy varies, with 33% of adult patients and 28% of child patients of allergists receiving this treatment, compared to lower percentages among patients of family practitioners and pediatricians .

Management of Food Allergies

The primary strategy for managing food allergies is strict allergen avoidance. In cases of accidental ingestion, appropriate treatment of allergic reactions, including the use of epinephrine for anaphylaxis, is critical. Emerging treatments under investigation include immunotherapy, biologics, and novel vaccines, which offer hope for more effective management in the future .

Preventive Measures

Preventive strategies for allergic diseases include breastfeeding and smoking cessation, which have been shown to reduce the risk of developing allergies in children. Additionally, early introduction of certain foods, such as peanuts, has been recommended to prevent the development of food allergies .

Conclusion

The diagnosis and treatment of allergies involve a combination of methods and strategies tailored to the type and severity of the allergy. Accurate diagnosis through appropriate testing is essential for effective management, while treatment options range from over-the-counter medications to specialized immunotherapy. Preventive measures and emerging treatments hold promise for reducing the prevalence and impact of allergic diseases in the future.
