Background: Amyloidosis is a rare disease that results from accumulation of inappropriately folded proteins causing organ failure and poor prognosis. In the last decade several options for therapy have emerged. We hypothesized that the trends and outcomes of solid organ transplantation (Tx) have increased and improved.
Methods: We analyzed the UNOS database and included patients with diagnosis of amyloidosis who received a primary single organ (Kidney, Liver and Heart) or combined organs (Heart-Kidney, Heart-Liver) between January 1987 and September 2014, for either light chain, transthyretin or other amyloidosis. We compared post-transplant outcomes in two separate eras: January 1987 to December 2004 (Era 1) and January 2005 to September 2014 (Era 2).
Results: From 1987 to 2014 a total of 1227 patients with amyloidosis were transplanted: kidney 591(48%), liver 249 (20%), heart 214(17%), heart-liver 50(4%) and heart-kidney 23(2%) (Figure). The five year survival for kidney tx improved from Era1 to Era2 from 66% to 82%, for liver tx from 54% to 70% and for heart tx from 54% to 69% (Figure). In a multivariate analysis, prominent risk factors for 1-year mortality after transplant for amyloidosis included recipient age for kidney (HR 1.06, p 0.01) and mechanical circulatory support (HR 5.42, p = 0.001) and body mass index (HR 0.9, p = 0.05) for heart transplant.
Conclusions: More patients with amyloidosis are considered for solid organ transplantation. Outcomes continue to improve and are now approaching survival rates comparable to non-amyloid patients.
