Late-onset of immunodysregulation, polyendocrinopathy, enteropathy, x-linked syndrome (IPEX) with intractable diarrhea

none8noThe syndrome of immune dysregulation, polyendocrinopathy, enteropathy, X linked (IPEX) is a rare disorder caused by mutations in the FOXP3 gene. Diarrhea, diabetes and dermatitis are the hallmark of the disease, with a typical onset within the first months of life. We describe the case of a twelve-year old male affected by a very late-onset IPEX with intractable enteropathy, which markedly improved after starting Sirolimus as second-line treatment. This case suggests that IPEX should always be considered in the differential diagnosis of watery intractable diarrhea, despite its unusual onset.noneDaniele Zama; Ilaria Cocchi; Riccardo Masetti; Fernando Specchia; Patrizia Alvisi; Eleonora Gambineri Gambineri; Mario Lima; Andrea PessionDaniele Zama; Ilaria Cocchi; Riccardo Masetti; Fernando Specchia; Patrizia Alvisi; Eleonora Gambineri Gambineri; Mario Lima; Andrea Pessio
