[Eosinophilic gastroenteropathy: a pediatric series]. / Gastroenteropatía eosinofílica: una serie pediátrica.

Eosinophilic gastroenteropathy (EoG) is an uncommon disease characterized by eosinophilic infiltration of the gastrointestinal (GI) mucosa. A chart review was performed searching for patients diagnosed between 2000 and 2010. EoG was diagnosed based on mucosal infiltration of 20 or more eosinophils/HPF in upper GI tract and more than 60 eosinophils/HPF in lower GI tract. Ten patients [median age: 10 mo. (r 2 mo.- 10 yr.)], 9 males, were diagnosed. Four presented with severe protracted diarrhea and weight loss, 2/10 abdominal distention and weight loss and 4/10 protein-losing enteropathy. Exclusive elemental or hypoallergenic diets were administered depending on the age of presentation with remission achieved in 4/10. Six required methylprednisolone to induce remission, 5 are still on budesonide. Due to the emergence of many cases of EoG in the last decade, we should increase our level of suspicion. Multicenter studies could contribute to define the best therapeutic approach for these patients.

Hepatitis autouinmune en niños. Presentación inicial como falla hepática fulminante / Autoimmune hepatitis in children. Initial presentation of fulminant hepatic failure

There are few cases reported of autoinmune hepatitis (AIH) tipe 2 presenting as fulminant hepatic failure (FHF) in children. The purpose of this study was to report three girls with AIH type 2 that presented as FHF. METHODS: Over a period of 12 years, 123 patients with AIH diagnosed based on international criteria, 9 (7 per cent were type 2.3 of them presented as FHF. Other etiologies (viral, metabolic and toxic) were ruled out. The treatment was started with prednisone (2 mg-kg-day) and azathioprine (2 mg-kg-day). EVOLUTION: Patients 1 and 3 died while waiting for liver transplant (LT) at 72 and 48 hours after initiating medical treatment. Patient 2 underwent LT3 days after starting treatment, with excellent evolution at 3 years and 7 months of follow up. CONCLUSIONS: 1--AIH type 2 was very infrequent in our group. 2--33 per cent of cases had initial presentation as FHF. 3--The course of the disease was aggressive, not responding to immunosupreessive therapy. The evolution was unfavorable in all patients. 4--LT is an alternative treatment for this severe disease.
