Brief Summary

Mitochondrial neurogastrointestinal encephalopathy (MNGIE) is an ultra-rare mitochondrial disease caused by mutations of the gen that codifies the enzyme thymidine phosphorylase The genetic defect results in systemic accumulation of the nucleosides thymidine and deoxyuridine. Clinically MNGIE is characterized by a combination of gastrointestinal and neurological manifestations, including severe gastrointestinal dysmotility, cachexia, ptosis, external ophthalmoplegia and sensorimotor neuropathy. Gastrointestinal symptoms are the most frequent first manifestation of the disease, and include early satiety, nausea, dysphagia, postprandial emesis, abdominal pain, abdominal distention, and diarrhea. The disease is relentlessly progressive and the cause of death is primarily related to digestive dysmotility. However, the specific motor dysfunctions that produce the symptoms, i.e., the underlying mechanisms, remain uncertain.

Outcome Measures

Primary Outcomes (2)

  • intestinal motility at diagnosis

    to assess the number of intestinal contractions (contractions per minute) during fasting and after the infusion of nutrients measured by high-resolution intestinal manometry

    In patients included, in the first 30 days from diagnosis

  • intestinal motility at diagnosis

    to assess the amplitude (mmHg) of contractions during fasting and after nutrients measured by high-resolution intestinal manometry

    In patients included, in the first 30 days from diagnosis

Secondary Outcomes (2)

  • intestinal motility response to hepatic transplant

    one and two years after hepatic transplant treatment

  • intestinal motility response to hepatic transplant

    one and two years after hepatic transplant treatment
