5 mesi, 2 episodi di vomito profuso, pallore e disidratazione comparsi dopo alcune h assunzione crema di riso.

14 RISULTATI – Test Diagnostici 1
DIAGNOSI FPIES : Prick Test e/o sIgE devono essere negativi? Among 160 subjects with FPIES, 24% had positive specific IgE to the FPIES food, which is referred to as ‘‘atypical’’ FPIES 70 – 60 – 50 – 40 – 30 – 20 – 10 – 00 56% 44% SI NO Caubet JC, JACI 2014; 134: 382-9 Clinica Pediatrica Università di Verona

15 RISULTATI – Test Diagnostici 2 DIAGNOSI FPIES: sempre
FPIES: Diagnosis DIAGNOSI FPIES: sempre necessario il TPO? There are no in vivo or in vitro tests with demonstrated specificity and sensitivity to diagnose FPIES OFC may not be necessary to make the diagnosis if the history of FPIES is very compelling (2 or more reactions with typical symptoms to the same food in a 6-month period and elimination of symptoms when the causative food is removed from the diet) 70 – 60 – 50 – 40 – 30 – 20 – 10 – 00 57% 43% SI NO Boyce J, J Allergy Clin Immunol 2010;126:S1-S58 Clinica Pediatrica Università di Verona

16 FPIES: Acute Managment TERAPIA FPIES «ACUTA» : Adrenalina cardine?
RISULTATI – Terapia 1 FPIES: Acute Managment TERAPIA FPIES «ACUTA» : Adrenalina cardine? Oral rehydration fluids (if mild) Intravenous fluids, 20 ml/kg boluses of isotonic saline (if moderate to severe) Metilprednisolone ev, 1mg/kg (max 60-80mg) (if moderate to severe) Epinephrin for hypotension for severe or unresponsive to fluids 70 – 60 – 50 – 40 – 30 – 20 – 10 – 00 26% 74% SI NO Järvinen KM, JACI in Pract; 2013; 1:317-22 Clinica Pediatrica Università di Verona

17 Cumulative probability of recovery from CMP-induced FPIES
Natural history of food protein-induced enterocolitis syndrome (FPIES) Katz Y, Curr Opin All Clin Immunol 2014; 14:229 Cumulative probability of recovery from CMP-induced FPIES Around 90% of FPIES patients recover by the age 3–5 years. Recovery from FPIES to solid foods occurs later than FPIES to Cow’s Milk or Soy.

18 FPIES: Long term Managment
RISULTATI – Terapia 2 FPIES: Long term Managment A quanti mesi dall’ultima FPIES «acuta» consiglieresti la Reintroduzione dell’alimento? 6-11 mesi 12-18 18-24 Allergologo 60% 70 – 60 – 50 – 40 – 30 – 20 – 10 – 00 17% 15% 8% Around 90% of FPIES patients recover by the age 3–5 years. Oral Food Challenge is warranted to determine when FPIES has resolved 1st Tolerance-OFC with cow’s milk at months of age. For other foods reports are insufficient, and should be considered for reintroduction to the diet 12–18 months after the last reaction, in a physician-supervised setting Clinica Pediatrica Università di Verona Järvinen KM, JACI in Pract; 2013; 1:317-22

19 CONCLUSIONE È necessaria una maggiore informazione riguardo all’FPIES, in merito alle diverse forme cliniche ed alla gestione terapeutica acuta ed a lungo termine. Clinica Pediatrica Università di Verona
