RESUMEN
Exclusive enteral nutrition (EEN) has been shown to be more effective than corticosteroids in achieving mucosal healing in children with Crohn´s disease (CD) without the adverse effects of these drugs. The aims of this study were to determine the efficacy of EEN in terms of inducing clinical remission in children newly diagnosed with CD, to describe the predictive factors of response to EEN and the need for treatment with biological agents during the first 12 months of the disease. We conducted an observational retrospective multicentre study that included paediatric patients newly diagnosed with CD between 2014-2016 who underwent EEN. Two hundred and twenty-two patients (140 males) from 35 paediatric centres were included, with a mean age at diagnosis of 11.6 ± 2.5 years. The median EEN duration was 8 weeks (IQR 6.6-8.5), and 184 of the patients (83%) achieved clinical remission (weighted paediatric Crohn's Disease activity index [wPCDAI] < 12.5). Faecal calprotectin (FC) levels (µg/g) decreased significantly after EEN (830 [IQR 500-1800] to 256 [IQR 120-585] p < 0.0001). Patients with wPCDAI ≤ 57.5, FC < 500 µg/g, CRP >15 mg/L and ileal involvement tended to respond better to EEN. EEN administered for 6-8 weeks is effective for inducing clinical remission. Due to the high response rate in our series, EEN should be used as the first-line therapy in luminal paediatric Crohn's disease regardless of the location of disease and disease activity.

OBJECTIVES: To describe the epidemiological features, clinical characteristics and outcomes of neonates diagnosed with liver failure, as well as determine prognostic factors. METHODS: Cohort study conducted at a single tertiary referral and university-affiliated pediatric center. Hospital records of all neonates diagnosed with liver failure between January 2003 and December 2015 were retrospectively reviewed, and data on clinical and laboratory findings, treatment, and outcomes were collected. Survival analysis (Kaplan-Meier) and Cox regression were performed to identify prognostic factors at diagnosis. Liver failure diagnosis was established using the pediatric acute liver failure study group's diagnostic criteria for every patient with coagulopathy and biochemical pattern of liver disease. RESULTS: Forty-five patients were included. In our series, most cases were secondary to ischemia (28.9%). Other causes were neonatal hemochromatosis (17.8%), viral infections (13.3%), and inborn errors of metabolism (13.3%). A total 55.6% (25/45) of the patients died (median age: 16 days; range 1-235 days). Alanine aminotransferase (ALT) at diagnosis was associated with higher mortality or the need for liver transplantation on day 21 after diagnosis (Pâ=â.006). For every 500 IU/L increase in ALT serum levels, the mortality/liver transplantation rate increased 1.3 times (hazard ratio 95% confidence interval: 1.1-1.6). Although ischemic neonatal acute liver failure presents with higher ALT levels, these cases appear to have better outcomes. Higher international normalized ratio tended to increase mortality/transplantation (hazard ratio 1.02; 95% confidence interval 0.91-1.2). CONCLUSIONS: Neonatal liver failure should perhaps be considered in the differential diagnoses of any coagulopathy. ALT and international normalized ratio levels at diagnosis could predict prognosis in the short term. Ischemic liver failure appears to have a better prognosis.

Ulcerative ileitis (UI) after restorative proctocolectomy (RPC) and ileoanal pullthrough procedure (IAPP) is a rare condition described as inflammation of the terminal ileum proximal to the anastomosis. It is mostly observed in ulcerative colitis (UC) and is designated as prepouch ileitis; sometimes with pouchitis, but not necessarily all the time. Its incidence in adults is less than 5%, but the information in children is limited. Pathogenesis is unknown, it has been considered as a disease by itself, independently on the underlying disease. It involves additional morbidity and impacts negatively on quality of life because there is no effective treatment so far. This study aims to review the cases of UI in our institution and to summarize their clinical features and management. A descriptive retrospective study of UI patients between 1990 and 2013 was conducted. Children with RPC and IAPP with clinical and pathological diagnosis of UI were included. Sociodemographic and clinical data, diagnostic, and therapeutic procedures were collected through medical records. UI was diagnosed in eight patients (six males) after RCP; four had UC, two had total colonic aganglionosis (TCA), and two had complex anorectal malformations (one cloacal exstrophy and one omphalopagus twin with bladder exstrophy). Different surgical techniques were used in each case: UC patients underwent IAPP, 50% with J-reservoir and 50% without it; posterior sagittal pullthrough was performed in those with anorectal malformations; one Soave and one Swenson procedure in those with TCA. In summary, three patients had reservoir and five did not. The median age at the IAPP and ostomy closure was 6 years (range 2 months-8 years) and 7 years (range 6 months-9 years), respectively. UI was found after a median of 23 months (range 1-48 months), all of them after digestive tract continuity was reestablished. The leading symptom was lower GI or gastrointestinal, both of them bleeding with abdominal pain, followed by abdominopelvic abscesses and malabsorption with weight loss. Pathology showed nonspecific inflammatory changes. Treatment included antibiotics, corticosteroids and/or immunosuppressive agents with variable response, requiring a new ileostomy in five cases. Ileitis disappeared after diversion. In our experience, UI after colectomy is not an exclusive feature of UC as has been previously described. Although it appears with pouchitis, the presence of a reservoir is not a must, suggesting that this is a different entity. No medical treatment has been really effective in our patients and diversion above this level stopped the process. Further studies on its pathogenesis and treatment strategies are necessary.
