Familial amyloidotic polyneuropathy (FAP-type I) was first described in Portugal by Andrade in 1952, a time when 54 among 64 patients (belonging to 25 families) originated from Póvoa do Varzim or its surrounding districts. Since then, a total of 1,233 patients, belonging to 489 pedigrees (so far unrelated), have been diagnosed at Centro de Estudos de(More)
Transthyretin amyloidosis is a progressive and eventually fatal disease primarily characterized by sensory, motor, and autonomic neuropathy and/or cardiomyopathy. Given its phenotypic unpredictability and variability, transthyretin amyloidosis can be difficult to recognize and manage. Misdiagnosis is common, and patients may wait several years before(More)
Two hundred thirty-one cases of neurocysticercosis are reviewed. Diagnosis was established by cerebral computed tomography during a seven-year period (1983-1989). One hundred and fourty-four (62%) presented with symptom-related disease (symptomatic neurocysticercosis and in 87 the diagnosis was incidental (asymptomatic neurocysticercosis). In symptomatic(More)
BACKGROUND Transthyretin amyloidosis is caused by the deposition of hepatocyte-derived transthyretin amyloid in peripheral nerves and the heart. A therapeutic approach mediated by RNA interference (RNAi) could reduce the production of transthyretin. METHODS We identified a potent antitransthyretin small interfering RNA, which was encapsulated in two(More)
BACKGROUND Transthyretin (TTR) amyloidosis is a rare, life-threatening, systemic, autosomal dominant condition occurring in adults, with two main forms: hereditary (associated with TTR gene mutations) and wild-type. Studies indicate considerable heterogeneity in disease presentation, with predominantly polyneuropathic, predominantly cardiac, or mixed(More)
We reviewed 1233 cases of familial amyloidotic polyneuropathy (FAP) from 489 Portuguese families registered at the Centro de Estudos de Paramiloidose, Porto, Portugal. It was found that in 159 cases, neither parent had shown symptoms of this hereditary dominant form of peripheral neuropathy. These cases appear to form a distinct group, with a later age at(More)
PURPOSE OF REVIEW Transthyretin familial amyloid polyneuropathy (TTR-FAP) is a highly disabling, life-threatening disease characterized by progressive sensorimotor and autonomic neuropathy. The profile of the disease across Europe is inadequately understood at present. RECENT FINDINGS The incidence and clinical presentation of TTR-FAP varies widely within(More)
Familial amyloid polyneuropathy (FAP) is a lethal autosomal dominant disorder in which fibrils derived from mutant forms of transthyretin (TTR), the normal plasma carrier of thyroxine (T(4)) and retinol-binding protein, are deposited in tissues. Over 80 TTR sequence variants are associated with FAP, but the amino-acid substitutions alone do not completely(More)
We report the 5-year results of our simultaneous pancreas-kidney transplantation (SPKT) program, started on May 2, 2000. Forty-two SPKT were performed on 42 type I diabetic patients with chronic renal failure. The procedure was performed with enteric diversion and vascular anastomosis to the iliac vessels. Immunosuppressive protocol included antithymocyte(More)
BACKGROUND The diagnosis of amyloidosis of all types is definitively made by demonstration of Congo red binding material in the affected tissues. Nerve biopsy was classically used to diagnose amyloid polyneuropathy but less invasive alternative types of biopsies have been proposed including labial salivary gland (LSG) biopsy, a minimally invasive procedure.(More)
