MaRDI English

French national reference center for rare digestive diseases (MaRDI)

To provide children and their parents with effective and peaceful therapeutic care, the team at the MaRDI reference center has developed a holistic and multi-professional approach as well as 4 therapeutic education programs: parenteral nutrition, enteral nutrition, IBD and transplantation, with at least one coordinating nurse for each.

We work with the main associations of patients and families developed around certain diseases or certain type of care.

We constantly ensure the safety and the best quality of life for children with rare digestive diseases and their families.

The transition to care by adult centers has been organized for several years now with Parisian hospitals (Beaujon, Georges-Pompidou, Saint-Antoine). It is based on anticipation, with, in particular, early transmission of medical information and shared « pediatric-adult » consultations.

Aware of the heaviness of the care and the importance of the issues, we are convinced of the need for care in a center whose expertise is based on years of work and experience in the field.

This reference center is affiliated with the FIMATHO rare diseases healthcare network and the ERNICA European reference network (ERN)

The MaRDI reference center was established at Necker hospital in 2004. It was a natural fit, as its gastroenterology and nutrition department had been involved for several decades in the field of rare intestinal diseases, whether those that lead to intestinal insufficiency and require parenteral nutrition (PN) or chronic inflammatory bowel diseases (IBD). Our center is internationally recognised, thanks to scientific communications and publications, but also thanks to the care of children from all over Europe and beyond.

As early as the 1970s, Professor Claude Ricour, faced with serious digestive diseases causing severe malnutrition, developed parenteral nutrition (PN) in France. He initiated its pursuit at home in 1981 leading to the creation, in 1984, in Necker, of the first « expert center for home parenteral nutrition » (HPN) for children. This therapy remains the main means of caring for children with intestinal insufficiency, whether it is linked to a short bowel syndrome, congenital enteropathy or certain neuro-muscular digestive diseases (chronic intestinal pseudo-obstruction, Hirschsprung’s disease). Thanks to a close and long-standing collaboration with the paediatric surgery team (Pr D.Pellerin and Pr Y.Révillon), it was also at Necker that the first intestinal transplant in children was carried out in 1987 and the first liver transplant associated with the intestine was performed in 1994. All these years have been marked by intense research activity which has led to considerable progress in the efficacy and safety of PN. We took an active part in the European Guidelines for PN in children published in 2005 and updated in 2018 in Clinical Nutrition.

The analysis of cohorts of patients with intestinal insufficiency or IBD and clinical research have enabled us to advance therapeutics and to highlight new rare intestinal diseases related to genetic mutations. Thanks to the many skills gathered on the Necker site and to the close links with the Imagine institute, we are continuing this essential research, particularly in molecular genetics with the Immunobiota program for the diagnosis of mutations in children with neonatal onset enteropathies or complex digestive immunopathologies (severe colitis, autoimmune enteropathies, etc.)

In the field of intestinal insufficiency, we have, today in Europe, the largest cohort of children in HPN: 150 children in active line and more than 700 since its initiation at the beginning of the 80’s and the largest series of children having received an intestinal transplant (more than 120 children). For children with short bowel syndrome, we currently have a treatment protocol with a recombinant intestinal hormone, GLP-2.

In the field of IBD, for two decades we have been facing a sharp increase in the incidence and demand for diagnosis (digestive endoscopy, medical imaging by MRI, pediatric proctology) and therapeutic care. We are therefore developing, with cohorts of more than 400 patients, adapted care pathways and numerous research programs, whether it concerns nutritional treatment in Crohn’s disease and, above all, biological treatments (biotherapy by monoclonal antibodies) .
