Abstract/OtherAbstract:
PURPOSE: To observe which symptoms of transthyretinrelated familial amyloidotic polyneuropathy (FAP) progressed in the long term after liver transplantation (LT), focusing on cardiac, kidney, and ocular symptoms.
METHODS: We reviewed the medical records of 34 Japanese patients with FAP, who underwent LT between 1994 and 2006. The mean follow-up period (±SD) after LT was 9.6 ± 3.4 years. Of the 34 patients, 30 had FAP amyloidogenic transthyretin (ATTR) Val30Met, 1 had FAP ATTR Ser50Ile, and 3 had FAP ATTR Tyr114Cys.
RESULTS: The 10-year survival rates from the onset of FAP and from the time of LT were 100% and 91.4%, respectively. Progression of ocular amyloidosis was seen in 17 (50%) patients, 13 of whom had de novo amyloid deposits in the vitreous body; progression of cardiac amyloidosis was seen in 10 (29%) patients, 4 of whom had newly granular sparkling echo on echocardiography, and 9 of whom had newly implanted pacemakers or implantable cardioverter-defibrillators. Although the mean serum creatinine levels did not increase significantly after LT in any of the patients, the estimated glomerular filtration rate had decreased significantly by 7 years after LT.
CONCLUSION: Although LT is life-saving for patients with FAP, we observed progression of the ocular and cardiac symptoms of FAP in a significant number of these patients over the long term after LT.
