Active clinical trials for "Amyloidosis"

The objective of this prospective observational study is to periodically monitor pre-symptomatic subjects carrying a mutation of Transthyretin (TTR), identified in the context of a family screening of affected proband, through instrumental methods and clinical scales in order to identify the first signs of clinically significant organ involvement by the disease. Healthy asymptomatic carriers will be subjected to regular monitoring through clinical evaluations and instrumental investigations defined by the consensus group (Conceicao et al.) in order to validate the criteria defined by this group to define the onset of the disease. A subgroup of carriers with scales and instrumental tests negative for damage to the peripheral nervous system or cardiac, but with subjective symptoms compatible with the disease, will be subjected to further instrumental tests not indicated by consent.

Clinical comparison of patients with transthyretin cardiac amyloidosis and patients with heart failure with reduced ejection fraction

Systemic transthyretin amyloidosis is an aging-related disorder. It is usually associated with cardiac disease but also extends to other organs. Recent studies found that idiopathic carpal tunnel syndrome patients may have amyloid deposition in tenosynovial tissue. The main aims of this project are the characterization of the association between idiopathic carpal tunnel syndrome and transthyretin amyloidosis and its evaluation as a predictive factor of cardiac amyloidosis

The study aims, by generating a large registry of patients with ATTR amyloidosis, including data at diagnosis and during follow up, to describe the natural history of ATTR amyloidosis in a real-world setting and to define and validate prognostic models, response criteria applicable at any point of the disease. The registry will also be used for data sharing and to allow the possibility of a close collaboration amongst the amyloidosis experts of the ARTC and all the physicians around the Country involved in the diagnosis and management of systemic amyloidosis. Thanks to the online registry, the diagnostic facility of the ARTC will be made available to requesting physicians.

Cardiac transthyretin (ATTR) amyloidosis is an infiltrative cardiomyopathy with an inexorably progressive clinical course and poor prognosis. The disease is caused by misfolding of the liver-derived precursor protein transthyretin as a result of an acquired wild-type variant (ATTRwt) or as a hereditary mutant variant (ATTRm). Application of single-photon emission computed tomography (SPECT) provides greater anatomic resolution, enabling the assessment of amyloid burden within individual left ventricle segments.This study aims to describe the pattern of regional myocardial distribution of 3,3-diphosphono-1,2-propanedicarboxylic acid (DPD) SPECT uptake among patients with ATTRwt and ATTRm. It will investigate the clinical, biochemical and echocardiographic, including left ventricle longitudinal strain profile in ATTRwt and ATTRm. Moreover, we will evaluate the presence and extent of DPD cardiac uptake among asymptomatic ATTRm variants carriers.This is a prospective multi-center observational study. The study, after obtaining prior written informed consent, will include consecutive patients who have Grade 1-3 cardiac DPD retention in scintigraphy. In addition, first-degree relatives of patients with ATTRm are going to be enrolled. Patients are going to undergo TTR gene sequencing to assess the presence of pathogenic variants associated with ATTRm. Both planar scintigraphy, SPECT and speckle-tracking echocardiography will be reviewed and interpreted using visual and quantitative approaches.

The purpose of this protocol is to generate a large registry of patients with AL amyloidosis.

The primary aim is to establish a prospective cohort of patients with plasma cell disorders (PCDs). All of the hospitalized PCD patients who are willing to sign the informed consent form (ICF) will be included in this study. Clinical characteristics, treatment options and responses will be collected. Peripheral blood, bone marrow aspirate and urine samples before and after the treatment will banked for future research. Our team will focus on the clinical and pathological features of PCDs, the correlation between the minimal residual disease (MRD) status and prognosis, and the role of Tumor Microenvironment (TME) in the pathogenesis and progress of PCDs.

The primary purpose of this protocol is to create a registry of patients with plasma cell disorders (PCDs), including for example the cancer multiple myeloma (MM), who complete the assessment, previously known as a "geriatric assessment," as is outlined in this protocol. Secondary objectives include measuring the response rate to participation of patients in this study, assessing patient satisfaction with the questionnaire, and gathering information that would lend support for future research into these types of assessments in patients with PCDs. Additionally the study offers an optional blood draw to look at a genetic marker of aging called p16INK4a (IRB 15-1899, IRB 15-0244).

Observational multicenter registry of cohorts with follow-up. Patients with heart failure, age ≥ 18 years, with clinical suspicion of cardiac amyloidosis and any LVEF value, treated in the field of Internal Medicine. Initially, a duration of two years was established to recruit at least 150 patients in the group with AC, and a follow-up of two years. Upon completion of the two years of follow-up, the continuity or completion of the registry will be assessed.

The purpose of this study is to collect and evaluate pregnancy outcomes, pregnancy complications, and fetal/neonatal/infant outcomes in women exposed to patisiran-LNP.
