- BACKGROUND: Signs of cardiac transthyretin (TTR) amyloidosis (ATTR) in patients with echocardiographic increase in interventricular septal thickness (IVST) are lacking.OBJECTIVES: To identify clinical and ECG/echocardiographic signs associated with increased IVST in ATTR.METHODS: Analysis of patients with baseline echocardiography in the Transthyretin Amyloidosis Outcomes Survey (THAOS) registry (N=1682). Patients were categorised into IVST classes according to the American Society of Echocardiography classification adapted to gender (ie, normal, mild, moderate, severe); then into two combined IVST classes (normal-mild and moderate-severe).RESULTS: 425 patients were included: 336 with a TTR mutation (m-TTR) and 89 with wild-type TTR (WT-TTR). 72% were men. Median (25th, 75th centile) age was 62 (45, 72) years. Non-Val30Met and WT-TTR were frequent in moderate (41% and 35%) and severe (50% and 33%) IVST classes. Median IVST was 15?mm (14, 16) (moderate) and 20?mm (18, 22) (severe). In the combined moderate-severe class, 85% of patients were ?55?years of age; 81% were men; 86% had blood pressure <140?mm?Hg; and 77% had increased right ventricle thickness (?7?mm). Up to 66% of patients had cardiac sparkling. Systolic dysfunction (left ventricular ejection fraction <50%), restrictive pattern and low voltage were less frequent, and observed in 49%, 18% and 33% of patients, respectively.CONCLUSIONS: Increased IVST, especially in men ?55?years with normal systolic blood pressure, increase in right ventricle free wall and valve thicknesses, and sparkling, should alert practitioners to the possibility of ATTR. Absence of restrictive pattern and low voltage should not rule out the suspicion.TRIAL REGISTRATION NUMBER: NCT00628745 (clinicaltrials.gov).

- Available data on antipsychotic-induced metabolic risks are often constrained by potential confounding effects due to prior antipsychotic treatment. In this study, we assessed the baseline prevalence of metabolic abnormalities and changes following treatment with five commonly-used antipsychotic drugs (haloperidol, amisulpride, olanzapine, quetiapine or ziprasidone) in first-episode, partially antipsychotic-naive patients with schizophrenia in the European first-episode schizophrenia trial (EUFEST). Overall baseline prevalence of metabolic syndrome (MetS) was 6.0%, with similar rates observed in the antipsychotic-naive patients (5.7%, 9/157) and in the other patients with only a brief prior exposure to antipsychotics (6.1%, 20/326). These results are consistent with the MetS prevalence rate estimated in a general population of similar age. Examination of individual risk factors showed 58.5% of subjects had one or more elevated metabolic risks at baseline: 28.5% demonstrated suboptimal HDL; 24.2% hypertension; 17.7% hypertriglyceridemia; 8.2% abdominal obesity; 7.3% hyperglycaemia. Increase in body weight (kg/month) occurred in patients treated with haloperidol (0.62 s.e. 0.11), amisulpride (0.76 s.e. 0.08), olanzapine (0.98 s.e. 0.07) and quetiapine (0.58 s.e. 0.09), which was significantly greater than that in the ziprasidone group (0.18 s.e. 0.10). The incidence rate of new diabetes cases over a 52-wk follow-up period was 0.82% (4/488). More patients experienced worsening rather than improvement of hypertriglyceridemia or hyperglycaemia in all treatment groups. Our findings suggest that in first-episode, partially antipsychotic-naive patients, the baseline prevalence rate of MetS appears to be no higher than that in the general population, but serious underlying individual risk factors nevertheless existed.

- INTRODUCTION: Gastrointestinal symptoms are common among patients with transthyretin familial amyloid polyneuropathy (TTR-FAP). This post hoc analysis evaluated the nutritional status of TTR-FAP patients treated with tafamidis while enrolled in clinical trials.METHODS: Nutritional status was measured by the modified body mass index (mBMI = BMI × albumin level). Treatment-related changes in mBMI were reported for 71 Val30Met TTR-FAP patients who completed an 18-month, randomized, double-blind, placebo-controlled trial and who continued into its open-label, 12-month extension.RESULTS: At month 18, mBMI worsened in the placebo group (n = 33) (-33 ± 16 kg/m(2) g/l, P = 0.04 versus baseline) but improved in the tafamidis group (n = 38) (+37 ± 14 kg/m(2) g/l, P = 0.01 versus baseline) such that the effect size between the groups was statistically significant (P = 0.001). By month 30 (completion of the open-label extension), placebo patients with 12 months of tafamidis treatment and tafamidis-treated patients with 30 months of treatment both tended to increase their mBMI (28 ± 19 kg/m(2) g/l and 16 ± 18 kg/m(2) g/l, respectively). Increase in BMI was most pronounced in patients with low BMI at entry into the studies.CONCLUSIONS: mBMI is well suited to monitor disease progression in TTR-FAP patients. The delay in neurological deterioration brought about by tafamidis treatment in clinical trials is associated with improvements in, or maintenance of, mBMI.

- BACKGROUND: Transthyretin amyloidosis is a systemic disorder caused by amyloid deposits formed by misfolded transthyretin monomers. Two main forms exist: hereditary and wild-type transthyretin amyloidosis, the former associated with transthyretin gene mutations. There are several disease manifestations; however, gastrointestinal complications are common in the hereditary form. The aim of this study was to explore the prevalence and distribution of gastrointestinal manifestations in transthyretin amyloidosis and to evaluate their impact on the patients' nutritional status and health-related quality of life (HRQoL).METHODS: The Transthyretin Amyloidosis Outcomes Survey (THAOS) is the first global, multicenter, longitudinal, observational survey that collects data on patients with transthyretin amyloidosis and the registry is sponsored by Pfizer Inc. This study presents baseline data from patients enrolled in THAOS as of June 2013. The modified body mass index (mBMI), in which BMI is multiplied with serum albumin, was used to assess the nutritional status and the EQ-5D Index was used to assess HRQoL.RESULTS: Data from 1579 patients with hereditary transthyretin amyloidosis and 160 patients with wild-type transthyretin amyloidosis were analyzed. Sixty-three percent of those with the hereditary form and 15% of those with the wild-type form reported gastrointestinal symptoms at enrollment. Unintentional weight loss and early satiety were the most frequent symptoms, reported by 32% and 26% of those with transthyretin gene mutations, respectively. Early-onset patients (<50 years) reported gastrointestinal complaints more frequently than those with a late onset (p < 0.001) and gastrointestinal symptoms were more common in patients with the V30M mutation than in those with other mutations (p < 0.001). For patients with predominantly cardiac complications, the prevalence of gastrointestinal manifestations was not evidently higher than that expected in the general population. Both upper and lower gastrointestinal symptoms were significant negative predictors of mBMI and the EQ-5D Index Score (p < 0.001 for all).CONCLUSIONS: Gastrointestinal symptoms were common in patients with hereditary transthyretin amyloidosis and had a significant negative impact on their nutritional status and HRQoL. However, patients with wild-type transthyretin amyloidosis or transthyretin mutations associated with predominantly cardiac complications did not show an increased prevalence of gastrointestinal disturbances.
