چکیده

Results The mean age of disease onset was 30 years (range: 27 to 43). All patients presented with paresthesias, temperature loss and progressive weakness at the lower extremities, urinary difficulties, diarrhea, postural dizziness and weight loss. The upper extremities were involved later during the disease progression. Neurological examination revealed loss of pain and temperature sensation in a glove and stocking distribution and distal weakness. All but two exhibited orthostatic hypotension. Four patients presented with carpal tunnel syndrome. Although cardiac arrhythmia was a common symptom to most patients, heart failure developed in 3 patients during the late phase of the disease. One patient presented with chronic kidney disease for which she was treated with hemodialysis. Electromyographic examination revealed evidence of denervation in the muscles of the lower limbs. Conduction velocities were slightly below the normal range. Rectal and/or sural nerve biopsy revealed the presence of amyloid deposit. Molecular analysis showed that all patients were heterozygotes for the TTR Met30 mutation. Eleven patients underwent orthotopic liver transplantation (OLTx) from 1993 to 2013. Eight of them showed remarkable improvement especially of their autonomic symptoms and muscle strength. They gained weight and their paresthesias also subsided. Of the operated patients, two died of post-operative complications, one of intracerebral hemorrhage and one of unrelated cause.

Peritransplant gastrointestinal symptoms in familial amyloidotic polyneuropathy.

OBJECTIVES Gastrointestinal dysfunction is a common complication in familial amyloidotic polyneuropathy, and gastrointestinal symptoms are associated with a patient's nutritional status. The object of this study was to evaluate changes in peritransplant gastrointestinal symptoms and the nutritional status of familial amyloidotic polyneuropathy patients using the modified body mass index followi...

Glial cells in familial amyloidotic polyneuropathy

INTRODUCTION Transthyretin V30M mutation is the most common variant leading to Familial Amyloidotic Polyneuropathy. In this genetic disorder, Transthyretin accumulates preferentially in the extracellular matrix of peripheral and autonomic nervous systems leading to cell death and dysfunction. Thus, knowledge regarding important biological systems for Transthyretin clearance might unravel novel ...

Familial amyloidotic polyneuropathy without familial occurrence: carrier detection by the radioimmunoassay of variant transthyretin.

A 47 year old woman with familial amyloidotic polyneuropathy (FAP) is reported, without familial occurrence of the disease. Her 81 year old mother and 53 year old sister were proved to be asymptomatic carriers for variant transthyretin (TTR) by means of the radioimmunoassay. It is suggested that unknown factor(s) may play a role in preventing or delaying the onset of the disease, producing vari...

Accelerating restrictive cardiomyopathy after liver transplantation in a patient with familial amyloidotic polyneuropathy: a case report

INTRODUCTION Hereditary amyloidodis is a rare disease process with a propensity to cause polyneuropathies, autonomic dysfunction, and restrictive cardiomyopathy. It is transmitted in an autosomal dominant manner, with disease onset usually in the 20s-40s. The most common hereditary amyloidogenic protein, transthyretin, is synthesized in the liver and lies on Chromosome 18. Over 80 amyloidogenic...
