Benefits of Paediatric to Adult Transition Programme in Inflammatory Bowel Disease: The BUTTERFLY Study of GETECCU and SEGHNP.

(1) Background: Transition is a planned movement of paediatric patients to adult healthcare systems, and its implementation is not yet established in all inflammatory bowel disease (IBD) units. The aim of the study was to evaluate the impact of transition on IBD outcomes. (2) Methods: Multicentre, retrospective and observational study of IBD paediatric patients transferred to an adult IBD unit between 2017-2020. Two groups were compared: transition (≥1 joint visit involving the gastroenterologist, the paediatrician, a programme coordinator, the parents and the patient) and no-transition. Outcomes within one year after transfer were analysed. The main variable was poor clinical outcome (IBD flare, hospitalisation, surgery or any change in the treatment because of a flare). Predictive factors of poor clinical outcome were identified with multivariable analysis. (3) Results: A total of 278 patients from 34 Spanish hospitals were included. One hundred eighty-five patients (67%) from twenty-two hospitals (65%) performed a structured transition. Eighty-nine patients had poor clinical outcome at one year after transfer: 27% in the transition and 43% in the no-transition group (p = 0.005). One year after transfer, no-transition patients were more likely to have a flare (36% vs. 22%; p = 0.018) and reported more hospitalisations (10% vs. 3%; p = 0.025). The lack of transition, as well as parameters at transfer, including IBD activity, body mass index < 18.5 and corticosteroid treatment, were associated with poor clinical outcome. One patient in the transition group (0.4%) was lost to follow-up. (4) Conclusion: Transition care programmes improve patients' outcomes after the transfer from paediatric to adult IBD units. Active IBD at transfer impairs outcomes.

Should Dientamoeba fragillis be looked for in pediatric digestive pathology of an unknown cause? A proposed pilot case-control study.

INTRODUCTION: Dientamoeba (D.) fragilis is a common intestinal protozoan with an unresolved clinical significance. The association between D. fragilis and the etiology of gastrointestinal symptoms in children is unclear. Metronidazole is often used for treatment. The aims of this study are to clarify the clinical relevance of D. fragilis in children with gastrointestinal symptoms, and to determine the clinical and microbiological efficacy of metronidazole in D. fragilis-infected children with gastrointestinal complaints. METHODS: A prospective case-control study was performed from October 2017 to February 2019. A total of 106 individuals aged 1-17 were included. Out of the 106; 59 showed gastrointestinal symptoms (case group), and 47 were without gastrointestinal symptoms (control group). We excluded 2 patients from the case group. D. fragilis was diagnosed by real-time PCR in stool samples. A 10-day course of oral Metronidazole was prescribed in D. fragilis positive children with GI symptoms. Clinical data before and after the treatment as well as peripheral eosinophilia in previous blood samples, were recorded. RESULTS: Of the 104 participants, D. fragilis was found in 17 (29.8%) children from the case group, whereas in the control group the parasite was detected in 11 patients (23.4%) with an odds ratio (OR) of 1.39 (IC 95% 0.53-3.75, p=0.46). The most prevalent clinical manifestation was abdominal pain (46/57, 80.7%). Seventeen cases with a positive PCR received anti-parasitic treatment according to the established protocol, although during the collection period we received only 11 stool samples to perform the post-treatment follow-up. The PCR of the D. fragilis remained positive in 3 patients (3/11, 27.27%). Despite achieving the eradication of the parasite, 4/8 patients (50%) continued with digestive symptoms. CONCLUSIONS: According to our study there were no differences between the D. fragilis infection in children with or without gastrointestinal symptoms. No relation was found between the clinical and microbiological responses after said D. fragilis treatment. Therefore, we conclude that it is not justified to look specifically for D fragilis in pediatric patients with abdominal symptoms.

Introducción: Dientamoeba (D.)fragilis es un protozoo intestinal muy común pero con una relevancia clínica incierta. El papel etiopatogénico de la D. fragilis en sintomatología gastro-intestinal no está claramente establecido. El metronidazol es con frecuencia el fármaco de elección. El objectivo de nuestro estudio fue determinar la relación entre D. fragilis y la presencia de clínica digestiva en población pediátrica así como valorar la eficacia del metronidazol en la resolución de los síntomas. Material y métodos: Estudio prospectivo caso-control realizado entre octubre 2017 y febrero 2019. Se incluyeron un total de 106 pacientes entre 1-17 años. 59 pacientes presentaban síntomas digestivos (grupo caso) y 47 pacientes asintomáticos (grupo control). Se excluyeron 2 pacientes del grupo caso. La presencia de D. fragilis se determinó por técnica de PCR real-time(PCR-RT) en muestra de heces. En los pacientes del grupo caso con PCR-RT positiva se realizó tratamiento con metronidazol durante 10 dias. Se recogieron datos clínicos antes y después del tratamiento asi como presencia de eosinofilia periférica. Resultados: De los 104 participantes, se detectó D. fragilis en el 17/59 (29,8%) en el grupo caso y en 11/47 pacientes del grupo control (23,4%) con una odds ratio (OR) de 1.39 (IC95% 0.53-3.75, p=0.46). El síntoma más frecuente fue el dolor abdominal (46/57, 80,7%). Los 17 pacientes del grupo caso recibieron metronidazol según protocolo y se realizó PCR-TR D. fragilis post-tratamiento en 11/17 pacientes. La PCR-RT persistió positiva en 3 pacientes (3/11, 27,27%). De los 8 pacientes que negativizaron PCR-RT, 4 (50%) continuaron con dolor abdominal. Conclusión: Según nuestro estudio no se encontró relación significativa entre la presencia de infección por D.fragillis y la existencia de sintomatología digestiva. Tampoco se observó mejoría clínica significativa en aquellos pacientes infectados que recibieron tratamiento.(AU)
