The transthyretin amyloidoses (ATTR) are invariably fatal diseases characterized by progressive neuropathy and/or cardiomyopathy. ATTR are caused by aggregation of transthyretin (TTR), a natively tetrameric protein involved in the transport of thyroxine and the vitamin A-retinol-binding protein complex. Mutations within TTR that cause autosomal dominant(More)
This phase II, open-label, single-treatment arm study evaluated the pharmacodynamics, efficacy, and safety of tafamidis in patients with non-Val30Met transthyretin (TTR) amyloidosis. Twenty-one patients with eight different non-Val30Met mutations received 20 mg QD of tafamidis meglumine for 12 months. The primary outcome, TTR stabilization at Week 6, was(More)
Resident ovarian macrophages have long been recognized as potential in situ regulators of ovarian function, presumably through local paracrine secretion of regulatory molecules (i.e. cytokines). One such macrophage product, interleukin-1 (IL-1) has recently been shown to exert profound regulatory effects at the level of the ovarian granulosa cell. In this(More)
Resident ovarian macrophages have been implicated in the regulation of ovarian function, presumably through local paracrine secretion of regulatory molecules (i.e. cytokines). One such macrophage product, tumor necrosis factor (TNF) alpha, has been shown to attenuate the gonadotropin-dependent differentiation of the somatic ovarian (estrogen-producing)(More)
Current views favor the notion that resident ovarian macrophages play an in situ role in the regulation of ovarian function through the local secretion of regulatory molecule(s) (i.e., cytokines). Herein we report on the potential ovarian relevance of one such macrophage product, tumor necrosis factor (TNF) alpha, a polypeptide capable of oncolytic as well(More)
Tafamidis, a transthyretin (TTR) kinetic stabilizer, delayed neuropathic progression in patients with Val30Met TTR familial amyloid polyneuropathy (TTR-FAP) in an 18-month randomized controlled trial (study Fx-005). This 12-month, open-label extension study evaluated the long-term safety, tolerability, and efficacy of tafamidis 20 mg once daily in 86(More)
BACKGROUND Transthyretin (TTR) amyloidosis is a progressive systemic disorder caused by misfolded TTR monomers that cumulatively deposit in the heart and systemically as amyloid. METHODS AND RESULTS This phase 2 open-label trial evaluated the stabilization of TTR tetramers using 20 mg of tafamidis daily at week 6 (primary end point), month 6, and month(More)
The Norfolk Quality of Life-Diabetic Neuropathy (QOL-DN) questionnaire is an instrument to assess QOL in diabetic polyneuropathy. The objective of this observational, cross-sectional study in 61 patients with V30M transthyretin familial amyloid polyneuropathy (TTR-FAP) and 16 healthy volunteers was to validate the Norfolk QOL-DN for assessment of QOL in(More)
BACKGROUND ATTR cardiac amyloidosis can result from a mutated variant of transthyretin (eg, V122I) or wild-type variant (ATTRwt). We evaluated pressure-volume (PV) indices at baseline and over time to further characterize abnormal pump function in these subjects. METHODS AND RESULTS Twenty-nine subjects (18 with ATTRwt and 11 with ATTRm (V122I) had(More)
Current evidence favors the hypothesis that granulosa cell-derived basic fibroblast growth factor (bFGF) may be the centerpiece of an intraovarian autocrine loop. In this report we examine the possibility that bFGF may also be involved in paracrine interactions at the level of the ovarian theca-interstitial cell. To this end, whole ovarian dispersates(More)
