“…Pork serum albumin is heat-labile, so well-cooked pork seems more likely to be tolerated, whereas fresh, dried, or smoked preparations of meat are more likely to elicit reactions. Cat-pork syndrome is more common in adults, but some pediatric cases were reported [ 61 , 62 ], even after consuming beef intestines [ 63 ]. Additionally, a case of FDEIA (Food-Dependent Exercise-Induced Anaphylaxis) was described in a 13-year-old boy that developed urticaria and dyspnoea during intense exercise after ingestion of pork [ 64 ].…”

Hidden and Rare Food Allergens in Pediatric Age

In food allergy management, the avoidance of the allergen that caused the reaction plays a fundamental role. Nevertheless, that can be thwarted in case of accidental exposure to a rare or hidden allergen, causing the adoption of a monotonous diet and a consequent reduction in the quality of life of the patient and their family. The identification of a rare and hidden allergen is an important diagnostic challenge, taking into account that a significant proportion of all food reactions is in reality due to them. The aim of the present review is to provide the pediatric allergist an overview of the possible sources of rare and hidden food allergens, taking into consideration the routes of exposure to these potential allergens with the main examples published in the scientific literature and the distinction between types of direct or cross-contamination. The identification of the allergen responsible for the reaction and the provision of a dietary advice customized for the specific individual’s dietary habits is essential to improve quality of life of the familiar nucleus and to reduce the risk of further allergic reactions.

“…Among these cross-reactivities, Pork Cat Syndrome is a less commonly encountered, yet intriguing, topic. This condition involves an immunoglobulin E (IgE)-mediated immune reaction to porcine albumin, initiated by sensitization through cat epithelium, generally manifesting post-adolescence [ 4 ]. Drouet et al first described this interesting interaction in 1994 [ 5 ], and few cases are reported sporadically.…”

Cross-reactivity between mammalian proteins, such as that in Pork Cat Syndrome, remains a topic of great interest. This syndrome, characterized by an immunoglobulin E (IgE)-mediated response to porcine albumin triggered by sensitization through cat epithelium, has been sparsely documented. We discuss a 41-year-old female who developed a pruritic rash within 30 minutes of consuming pork. Notably, she exhibited elevated serum IgE levels with specific reactions to cat dander, dog dander, and pork. A skin prick test for pork was positive. The patient was treated conservatively with allergen avoidance, vitamin D supplementation, fexofenadine, and doxycycline for systemic reactions, and topical corticosteroids for localized skin reactions, yielding a resolution of symptoms. This case underscores the significance of recognizing rare cross-reactivities in allergy and immunology and the manifestations of Pork Cat Syndrome, necessitating a comprehensive patient history and awareness for improved diagnosis and management.

“…Including our present patient, 4 cases were in children younger than 10 years ( Table I ). 7 , 8 , 9 All 4 patients were highly sensitized to cat dander, with extremely high Fel d 2 levels despite their young age. The 4 cases were characterized by daily contact with multiple cats and/or dogs since infancy and by poorly controlled atopic dermatitis that developed from infancy to early childhood.…”
