The NACHO Trial (Nut Allergy Children OIT)
Most food allergies that begin in early childhood are mild and resolve by school age, but nut allergies persist in about 80-90% of individuals into adulthood. The consumption of nuts, particularly cashew nuts, has increased dramatically in Finland in the 21st century, leading to a rise in severe allergic reactions to cashew nuts among young children. Of the food anaphylaxis cases reported in the Finnish Anaphylaxis Registry between 2015-2020, 49% were caused by nuts, with cashew nuts being the most common trigger. The standard treatment for nut allergies is strict avoidance of nuts and symptom management with emergency medications. Oral immunotherapy (OIT) is a food allergy...

The Potential Role of Compounds Derived From Ultra-processed Foods in Pathogenesis of Eosinophilic Esophagitis
Eosinophilic esophagitis (EoE) is a chronic antigen-mediated inflammatory disease of the esophagus that affects both children and adults. The incidence and prevalence of EoE is rapidly increasing in Western countries with an estimated incidence of 6.6 per 100,000 person-years (95% CI, 3-11.7) in children and 7.7 per 100,000 person-years (95% CI, 1.8-17.8) in adults. Clinically, it is characterized by various symptoms related to esophageal dysfunction, including vomiting, regurgitation, feeding difficulties, epigastric heartburn, dysphagia, or food bolus impaction, and may cause growth retardation. Diagnosis is made on the basis of clinical symptoms and histological evidence of...

The Potential Role of Compounds Derived From Ultra-processed Foods in the Pathogenesis of Atopic Dermatitis in Pediatric Age
Atopic dermatitis (AD) is a common chronic inflammatory skin condition, primarily affecting children in urban and high-income areas. Its prevalence has increased significantly over the past 30 years, with up to 20% of children affected, often within their first year of life. AD is characterized by erythematous, scaly, pruritic lesions, xerosis, and frequent atopy, with distinct clinical features in children compared to adults. The pathophysiology of AD involves skin barrier dysfunction, immune response alterations, and environmental triggers. Genetic factors, particularly mutations in the filaggrin gene, play a significant role in severe AD, leading to increased water loss and...

The UFIM (Ultraprocessed Foods In Breast Milk) Project
In last decades, a change in dietary habits has been observed in industrialized countries characterized by a drastic increase in the consumption of ultra-processed foods (UPF, Ultra-Processed Foods). As defined by the NOVA classification, UPFs are industrial formulations of food substances added with colourings, flavourings, emulsifiers, thickeners and other additives. Among the main compounds of UPFs are the advanced glycation end-products (AGEs). Increasing evidence suggests an association between dietary exposure to AGEs and the development of chronic non-communicable diseases, such as obesity and allergies, in the general population, through increased oxidative stress and...

Tolerability of Goat Milk Protein in Eosinophilic Esophagitis Patients With Cow Milk Protein Trigger
Eosinophilic esophagitis (EoE) is a chronic immune mediated disease characterized by eosinophilic infiltration in esophageal epithelium and resulting in esophageal dysfunction. While the exact pathogenesis is yet to be elucidated, EoE is considered an atopic disease. This classification is in part due to the inflammatory infiltrate of eosinophils, basophils and T-cells producing Th2 cytokines, yet it may also be triggered by environmental allergens. In addition, the rates of atopy are approximately 3 times higher in patients with EoE than in the general population. Furthermore, and most convincing, EoE is successfully managed with dietary exclusion of triggering groups in both...

Tolerance in Beekeepers
Beekeepers experience multiple bee stings each year. Many of these beekeepers (25-60%) become sensitized to bee venom through the production of specific antibodies that target the bee venom. Although these antibodies are important in the triggering of an allergic reaction only a small number of sensitised beekeepers go on to have an allergic reaction with symptoms away from the site of the sting. These reactions can be severe and are known as anaphylactic reactions. The study investigates why some beekeepers develop severe allergic symptoms after bee stings while others do not. This study will explore factors in the blood that protect sensitised individuals from having...

TRANS-FOODS: Preventing Peanut Allergy Through Improved Understanding of the Transcutaneous Sensitisation Route, Novel Food Processing and Skin Care Adaptations
This project aims to study the immune responses to peanut allergen in those with a skin barrier defect with and without skin massage, specifically it aims to: 1. Establish if peanut allergen components can pass into human skin through regular massage using the peanut protein-containing extract. 2. Clarify whether this effect is amplified in those with an impaired skin barrier (AD and dry skin vs healthy controls). 3. Assess whether peanut protein components can be detected in interstitial skin fluid (ISF) using a suction device. 4. Test whether peanut protein components present in ISF are able to induce activation of basophils in blood of...
