Definition
This section has been translated automatically.

Food protein-induced enterocolitis syndrome, also known as FPIES, is a rare, sometimes acute and severe, non-IgE-mediated gastrointestinal food hypersensitivity.

Occurrence/Epidemiology

No sex preference

Etiopathogenesis
This section has been translated automatically.

Aetiopathogenetically, an intolerance reaction to food proteins (which has not been defined in detail so far) forms the basis.

The following foods are the most common triggers: milk or dairy products, soya, cereals; more rarely: rice, oats or fish or egg products.

Manifestation
This section has been translated automatically.

The disease usually affects very young infants. Very rarely teenagers or adults are affected.

Clinical features
This section has been translated automatically.

Often after the first contact with the triggering food a profuse, repetitive vomiting occurs 1-4 hours after ingestion, often accompanied by diarrhoea with the risk of dehydration, weight loss, possibly accompanied by fever. Anaphylactic reactions up to severe shock are possible.

If left untreated, the condition leads to weight loss and growth disorders in infants.

In individual cases, tolerance can develop over the course of years (proven in cases of hypersensitivity to fish proteins).

Laboratory
This section has been translated automatically.

Frequently marked blood eosinophilia. The severity of eosinophilia is correlated with vomiting, bloody stools and diarrhoea. For example, in larger Japanese collectives, patients with diarrhoea only showed lower levels of eosinophilia than those with complete symptoms. CRP is elevated especially in febrile FPIES. No detection of specific IgE antibodies.

Diagnosis
This section has been translated automatically.

The diagnosis is made through an elimination diet with a non-allergenic special food.

Diagnosis verification: should be done by oral provocation. Always perform under stationary clinical conditions!
