Background and objective: Familial amyloid polyneuropathy (FAP) is the most prevalent type of hereditary systemic amyloidosis. It is an autosomal dominant disease characterized by the deposition of an abnormal variant transthyretin. It has a worldwide distribution, with localized endemic areas in Portugal, Sweden and Japan. In Spain there is an endemic focus, located in Mallorca. Liver transplantation is the only curative option for patients with FAP. The aim of this study was to describe the clinical and demographic characteristics of patients transplanted with a diagnosis of PAF. Material and method: Six patients with PAF underwent liver transplantation between April 1986 and December 2012. Results: The mean age was 57.7+16 years, patients of Spanish origin were older than 60 years. All patients had progressive symptoms as mixed polyneuropathy. In 2 patients, combined heart-liver transplants sequentially were performed. Patient survival and graft was 80% at one, 3 and 5 years. Conclusions: The only effective treatment for etiologic PAF is liver transplantation. Early detection is the key to the treatment and control, avoiding the irreversible organ damage.
