BACKGROUND AND AIMS: Domino liver transplantation (DLT) has been used to address the shortage of donor organs. However, recipients of liver grafts from patients with hereditary transthyretin amyloidosis (ATTRv) develop de novo transthyretin (TTR) amyloidosis. Our aim is to describe the clinical presentation of patients with acquired TTR amyloidosis and compare the rate of neuropathy progression (NP) with untreated ATTRv amyloidosis with neuropathy (ATTRv-NP) patients.
METHODS: Patients with acquired TTR amyloidosis after DLT followed at a reference centre were evaluated. Medical records were reviewed for clinical characterization and systematic assessment of neuropathy. NP was defined as an increase in neuropathy impairment score of the lower limbs (NIS-LL) at 12 months and compared to a historical control group of untreated ATTRv amyloidosis patients.
RESULTS: Twenty-four patients with acquired ATTR amyloidosis were included. Time from DLT to neuropathy onset was 9 ± $$ \pm $$ 2.0 years and the majority of patients reported feet sensory changes as first symptom. Thirteen patients with ≥ 2 evaluations with 12-months interval were analysed. Almost all patients developed a neuropathic phenotype with small nerve fibre involvement. Neuropathy progression was similar to untreated ATTRv-NP patients.
INTERPRETATION: Recipients from liver grafts of ATTRv patients develop de novo amyloidosis with clinical presentation and NP similar to untreated ATTRv amyloidosis patients. Study of these patients might help elucidate the pathways for ATTR fibril formation.
