We report for the first time the case of allergy to egusi seeds in an atopic child of Nigerian origin with allergy to other seeds and nuts. This case highlights the need to know and explore less common foods as potential allergens, the importance of modified skin prick testing and the basophil activation test to support the diagnosis of rare food allergies and of awareness about world cuisine and exotic foods as potential allergens.

This work aimed to determine if it was possible to eliminate or reduce the content of the Api g1 allergen in celery juice by oxidation, utilising its natural polyphenol oxidase (PPO) content. We attempted to determine a possible relationship between the enzymatic browning of celery juice and the reactivity of the Api g1 allergen. Pressed celery juice was stirred, and samples for the colour measurement and allergenicity, determined using the Western Blot (WB) method, were collected at pre-defined times. Oxidation failed to eliminate the allergenicity of pure celery juice. Further trials were focused on celery allergen elimination in apple-celery juices mixtures in ratios of 3:1, 5:1, and 7:1. We selected the 5:1 ratio as the most acceptable from the sensory perspective, and monitored its allergenicity using the WB method, basophil activation test, and skin prick testing. The WB test showed that oxidation, caused by stirring for 120 min, reduced the allergenicity of the mixture. However, the basophil activation test showed no reduction in the allergic response to the oxidised juice mixture. Skin testing showed that the oxidised juice mixture stirred for 120 min exhibited a significantly lower reaction than the juice mixture stirred for 60 min or celery and apple juice stabilised with ascorbic acid. Due to the contradictory results in different tests, the method cannot be declared successful or safe, even for mixtures of apple-celery juices.

The prevalence of allergic diseases in Poland and in the world continues to rise in recent years. The most commonly used methods for diagnosing IgE – dependent allergies are skin prick testing (SPT) and assessment of specific IgE (sIgE) directed against specific allergens. However, both methods have some disadvantages and the obtained results may be inconsistent. In particular, routine diagnostic tests are not always effective for some drugs and foods. Consequently, additional laboratory tools should be used. Basophil activation test (BAT) based on flow cytometry is a promising diagnostic method. The present paper demonstrates the usefulness and effectiveness of BAT protocols in allergy diagnosis in scientific research. In comparison to routinely used diagnostic methods, BAT is an expensive and complicated laboratory tool. However, it offers the possibility to efficiently and effectively recognize allergies. Introducing BAT into routine diagnostics in allergology is problematic because this method has not yet been standardized and validated. Therefore, there is a justified need to continue research in this field. If standardized and validated, BAT may offer a reasonable improvement in allergy diagnostics in the future.
