BACKGROUND Familial amyloid polyneuropathy (FAP) type I is caused by a mutated transthyretin (TTR V30M) and characterized by a sensorimotor and autonomic neuropathy. Renal, cardiac, and ocular abnormalities can also occur. Anemia has been described in previous reports, but its prevalence in Portuguese FAP patients is not precisely known. The aim of this(More)
BACKGROUND Anemia with low serum erythropoietin (EPO) is common in Portuguese transthyretin V30M amyloid polyneuropathy (FAP). Low EPO production can be observed before clinical disease. Renal amyloidosis is observed in FAP, mainly in the medulla. Renal manifestations correlate with glomerular and vascular involvement, but not with tubulointerstitial(More)
Familial amyloid polyneuropathy type I (FAP-I) is caused by a mutant transthyretin (TTR V30M) produced by liver, and orthotopic liver transplantation (OLT) is a widely accepted treatment for stopping the major production of TTR V30M. Anemia affects 24.8% of symptomatic FAP-I patients with low erythropoietin (Epo) levels, suggesting a blockage of(More)
BACKGROUND Fibrinogen A α-chain (AFib) amyloidosis results from autosomal-dominant mutations in the gene encoding AFib (FGA). Patients with this disorder typically present with proteinuria. Isolated cases of AFib amyloidosis, carrying the FGA p.Glu545Val variant, were identified in the district of Braga, in northwest Portugal. This observation led us to(More)
F amyloidotic polyneuropathy (FAP), Portuguese type, or ATTRV30M amyloidosis is an autosomal dominant inherited disorder caused by a mutation in the transthyretin gene, with a valine/methionine substitution at position 30 (TTRV30M). FAP is characterized by a progressive sensory/ autonomic polyneuropathy and multiple organ dysfunction. Liver transplantation(More)
Familial amyloidosis TTR V30M (FAP-I) usually presents as a sensorimotor and autonomic neuropathy. Anemia was first described in this disease more than 20 years ago and classified as an anemia of chronic disease. However, so far no studies have addressed the role of inflammatory proteins in this disease. The anemia affects 24.8% of symptomatic FAP-I(More)
