Microvillous inclusion disease (MVID) typically appears with severe chronic diarrhea in the few days after birth and rapidly causes dehydration and metabolic acidosis. In this context, presenting two novel cases, we underline the crucial importance of mutation analysis for the diagnosis of this disease that may be easily misdiagnosed.

Microvillous Inclusion Disease: An Exceedingly Rare Condition With a New Treatment.

Article Synopsis
- Syndromes with congenital diarrhea, hearing loss, and intrahepatic cholestasis are rare and often misdiagnosed as PFIC, but recent genetic studies have identified new genes related to these disorders.
- A 20-year-old woman, diagnosed with PFIC type 1 during childhood, experienced a resurgence of symptoms after a long period of being symptom-free, leading to the use of odevixibat for treatment.
- Whole genome sequencing revealed novel mutations indicating microvillous inclusion disease (MVID), and odevixibat showed effectiveness in alleviating cholestatic pruritus associated with this condition.
Aims: To report the results and successes of intestinal transplantation (ITx) in the most active European centres, to emphasize that, although it is a difficult procedure, it should remain a therapeutic option for children with total, definitive and complicated intestinal failure when intestinal rehabilitation fails.
Methods: We retrospectively collected data about all patients less than 18 receiving an ITx from 2010 to 2022 in 8 centres, and outcomes in July 2022.
Results: ITx was performed in 155 patients, median age 6.
Myosin Vb as a tumor suppressor gene in intestinal cancer.

Colorectal cancer causes >900,000 deaths every year and a deeper understanding of the molecular mechanisms underlying this disease will contribute to improve its clinical management and survival. Myosin Vb (MYO5B) regulates intracellular vesicle trafficking, and inactivation of this myosin disrupts the polarization and differentiation of intestinal epithelial cells causing microvillous inclusion disease (MVID), a rare congenital disorder characterized by intractable life-threatening diarrhea. Here, we show that the loss Myosin Vb interfered with the differentiation/polarization of colorectal cancer cells.

Infants with intestinal failure associated liver disease (IFALD) requiring liver and bowel transplant have a high mortality on the transplant waiting list due to the scarcity of the size-matched donor organs. Bridging liver transplantation has been used to allow the children to grow to a reasonable size so that a combined liver and small bowel transplant could be performed in the future. We report on two children with irreversible intestinal failure (ultra-short bowel syndrome secondary to gastroschisis and microvillous inclusion disease) with IFALD who underwent bridging liver transplantation at our institution.

Congenital enteropathies (CE) are a group of rare inherited diseases with a typical onset early in life. They involve defects in enterocyte structure or differentiation. They can cause a severe condition of intestinal failure (IF).
