Food protein induced enterocolitis syndrome in adults.

Food protein induced enterocolitis syndrome (FPIES) belongs to a group of IgE-independent food allergies. It is the domain of paediatric patients, but it can also occur in adults. In this disease there is a life-threatening risk resulting from the possibility of a severe course of the disease and the development of hypovolemic shock. The disease was first defined in the mid-1970s. Knowledge about this disease is extremely low, we do not know its exact frequency, and the disease itself usually appears between 2 and 7 months of age. FPIES occurs mainly in formula-fed infants, typically 1-4 weeks after formula introduction, very rarely in breastfed infants, but may also develop in adults.
