Clinical presentation and management of foodprotein‐induced enterocolitis syndrome in 113 Swedish children
Background
Food protein‐induced enterocolitis syndrome (FPIES) is a non‐IgE‐mediated food allergy causingsevere acute gastrointestinal symptoms and lethargy, mainly affecting infants and young children. There are geographic variations in its clinical features. This study aimed to describe the clinical characteristics and management of FPIES in Swedish children.
Methods
The study included children who presented with acute FPIES during 2008–2017. All Swedish pediatric departments (n = 32) were invited to report their known patients. Data were collected through chart reviews and interviews with parents.
Results
Eighteen pediatric departments contributed and 113 patients were included. Most had a family history of atopy (74%) and 51% had an atopic disease. Common trigger foods were cow's milk (26%), fish (25%), oat (22%) and rice (8%). Most patients(85%) reacted to a single food. The median age at first reaction was 3.9 months for cow's milk and 6.0 months for other foods(P<0.001, range 1.0 month to 9 years). Repetitive vomiting (100%), lethargy (86%) and pallor (61%) were common symptoms; 40% had diarrhea. Sixty percent visited the emergency department and 27% of all patients were hospitalized. Most patients were diagnosed clinically (81%). Specific IgE for the trigger food was positive in 4/89 tested patients (4%) and skin prick test for the trigger food was positive in 1/53 tested patients (2%).
Conclusions
In our Swedish studyof 113 children, cow's milk, fish and oat were the commonest trigger foods.Most patientsreacted to a single food and IgE sensitization was rare.
