Active clinical trials for "Amyloidosis"

The study will investigate the stabilization effects of Tafamidis utilizing cardiac imaging cardiac magnetic resonance imaging (CMR). The investigators propose to pursue the following specific aims: Utilize cardiac magnetic resonance to assess stabilization of ATTR after Tafamidis therapy based on extracellular volume mapping. Investigate left ventricular myocardial mass, native T1, T2, and extracellular volume mapping after 12 month follow-up. Utilize cardiac magnetic resonance feature tracking at baseline and at 12 month follow-up.

Increased circulating b-amyloid and decreased Mitochondrial-derived peptide (MOTS-c), a peptide improving tissue insulin sensitivity, are reported in diabetes. The investigators plan to investigate the association of both biofactors with high on-clopidogrel platelet reactivity and cardiovascular mortality in type 2 diabetic patients with Coronary artery disease

To set up a Brazilian strategy for early diagnosis of cardiac amyloidosis using new modality of echocardiography, the 3D echocardiography, and the level of myocardial deformity by measuring the Strain Longitudinal through the technology Speckle Tracking.

This study is intended to examine the impact of learning amyloid brain imaging results among asymptomatic older adults, and how to safely communicate these results and educate on the risk of developing Alzheimer's disease.

Specific, standardized, comprehensive, universally accepted Patient-Reported Outcome Measures (PROMs) are currently lacking for variant and wild-type cardiac amyloid transthyretin amyloidosis (v-ATTR/wt-ATTR). Our goal is then to create two scores able to provide a cumulative assessment of cardiac involvement, peripheral neuropathy (in v-ATTR), and comorbidities, and their impact on the quality of life. In the setting of a nationwide collaboration involving 5 main Italian referral centers for this condition (in Ferrara, Florence, Pavia, Pisa and Messina), a panel will be created, including experts of ATTR cardiomyopathy, neurologists, geriatricians, health management specialists, as well as patients with either variant or wild-type ATTR cardiomyopathy (n=50). The most clinically relevant domains for patients (such as physical limitations, symptoms, self-efficacy and knowledge, social interference, quality of life, age-related issues, social and family environment, frailty, comorbidities) will be identified. Two sets of 30 items (one for variant and another for wild-type ATTR cardiomyopathy) will be created in collaboration with patients. Questions will be formatted for gender neutrality, clarity, interpretability, and possible foreign language translations. PROMs scores will be validated through administration to around 250 consecutive outpatients. Score performance will be evaluated in terms of internal consistency, response to clinical changes, comparison with conventional clinical measures. The time needed for completion, the clarity of questions and the need for assistance from a family caregiver will be evaluated. This project will hopefully lead to the identification of disease-specific metrics that may serve as a clinically meaningful outcome in cardiovascular research, patient management, and quality assessment.

Purpose of this study is to determine whether keeping SAA on normal or near normal level will delay progression of renal failure in patients with amyloidosis secondary to FMF.

OBJECTIVES: I. Analyze prospectively the course of amyloid deposition in patients with primary, secondary, myeloma-associated, and hereditary amyloidosis. II. Determine abnormalities of humoral and delayed-type hypersensitivity in these patients. III. Identify prognostic factors in hereditary amyloidosis and develop tests for genetic defects associated with systemic amyloidosis. IV. Diagnose familial amyloidotic polyneuropathy (FAP) prior to symptom onset. V. Validate the correlation of low serum prealbumin and retinol binding protein levels with amyloidosis in patients with FAP.

TITLE: Study of Prevalence of Amyloidosis in Heart Failure: PREVAMIC. DESIGN: Multicenter, observational, cross-sectional, prospective, cohort study with a one-year follow-up. 44 hospitals from Spain will participate. OBJECTIVES. PRIMARY: To estimate the current prevalence of different types of cardiac amyloidosis (CA) in patients with heart failure, aged 65 years and older, with LVH > 12 mm and any LVEF value, managed in Internal Medicine departments. SECONDARY: To describe the clinical, laboratory and echocardiographic features of patients with CA. To compare one-year readmissions and mortality rates in patients with and without CA. INCLUSION CRITERIA: Inpatients or outpatients with heart failure, aged ≥ 65 years, both genders, under the care of internists. They should have a NYHA Class II-IV, echocardiogram performed in the previous 24 months, any value of LVEF, LVH: septum or posterior wall > 12 mm, diuretic treatment in the last 6 months and NTproBNP> 1800 pg/ml or BNP> 400 pg/ml in acute hear failure, or NT-proBNP >600 pg/ml o BNP >150 pg/ml in stable condition. POPULATION: Heart failure outpatients or inpatients of Internal Medicine Services. It is expected to include around 450 patients. ANALYSIS: To calculate the prevalence of TTR-CA and other types of CA. To compare the clinical, analytical, echocardiographic, and readmissions and mortality rates during one-year in patients with and without CA.

In this observational study, the investigators aim to evaluate whether changes in the retinal and choroidal circulation, as assessed by Optical Coherence Tomography (OCT) and the quantification of retinal amyloid deposits using auto-fluorescence and hyperspectral retinal imaging, are correlated with the degree and subtype of dementia and with the presence or absence of a positive amyloid scan. For this purpose, patients with established Alzheimer's Disease (AD) and Lewy Body Dementia (LBD), as well as amyloid positive and amyloid negative Mild Cognitive Impairment (MCI) and aged matched cognitively intact patients will be included in this cross-sectional study.

This is a pilot study to explore and identify changes in molecular processes within the oral mucosa that are associated with the development of oral mucositis (OM) in patients treated with Melphalan who undergo autologous peripheral blood stem cell transplantation.
