Introduction

Although potatoes are a staple food consumed worldwide, allergy to potato remains uncommon. However, potato sensitisation can present with a wide range of clinical manifestations, especially in children with atopic conditions.

Aim

This study aimed to assess the demographic and clinical features of children sensitised to potato.

Material and methods

Twenty-five individuals with potato sensitisation participated in the study, with skin prick tests confirming sensitisation to raw or commercial potato allergens. Demographic data, IgE and eosinophil levels, and family history of allergic diseases were recorded. Allergic rhinitis and atopic dermatitis were diagnosed based on established guidelines, and anaphylaxis was assessed using standardised criteria

Results

Results revealed a predominance of males (52%) with a mean age of 18.5 months. Atopic dermatitis was the most common clinical presentation, affecting 48% of patients, followed by urticaria (44%) and anaphylaxis (4%). Sensitisation to other allergens, particularly egg white and grass pollen, was prevalent among the study population. Recurrent reactions after potato consumption were observed in some patients, necessitating elimination from the diet. Notably, potato sensitisation often coexisted with other allergic conditions such as allergic rhinitis and asthma.

Conclusions

This study sheds light on the diverse clinical manifestations of potato sensitisation, ranging from skin-related symptoms to potentially life-threatening anaphylaxis. While potato allergy remains uncommon, its recognition is crucial for accurate diagnosis and management, particularly in children with atopic dermatitis who may not respond to conventional treatments. Further research is needed to elucidate the underlying mechanisms of potato sensitisation and develop optimal diagnostic and therapeutic strategies.
