Malnutrition and gastrointestinal dysfunction as prognostic factors for survival in familial amyloidotic polyneuropathy

The investigation disclosed that a short time interval between the onset of neurological and of gastrointestinal symptoms is associated with a decreased survival time. The mBMI was closely related to time before death, duration of gastrointestinal disturbances, malabsorption and functional capacity. The mBMI appears to be well suited to monitoring disease progress and gives prognostic information.
