Active clinical trials for "Amyloidosis"

In this clinical study, a single-center retrospective cohort study was used to explore the clinical characteristics and risk factors of patients with multiple myeloma myocardial amyloidosis. An exploratory study was conducted to compare the effects of various sublayer factors (M protein, electrocardiogram, echocardiography, CD138, chromosome abnormalities, etc.) on patients' survival. On this basis, a hierarchical diagnostic model (1-2-3-4) for patients with multiple myeloma complicated with myocardial amyloidosis was established based on the phenoomics of NMR and mass spectrometry, and the prognosis was evaluated simultaneously, in order to create an early, non-invasive, sensitive and quantitative diagnostic model for multiple myeloma complicated with myocardial amyloidosis, and lay a foundation for the early application of effective treatment.

Cardiac amyloidosis is a condition where the heart muscle, amongst other tissues, is infiltrated by the abnormal build-up of proteins called amyloid. This stiffens and thickens the heart muscle over time which makes it less efficient and puts further stress and strain on the other chambers of the heart, leading to heart failure. The commonest form, that affects predominantly the elderly, is called 'wild-type' ATTR amyloid (TTR is the protein that accumulates). In this condition a patient has a 60% chance of admission to hospital each year after diagnosis. There is no current treatment for ATTR amyloid other than using water tablets to reduce excess fluid and prevent more serious fluid build up in lungs and other tissues. Increasing body weight is the most reliable clinical sign of this fluid build up. Tele-monitoring is the practice of monitoring patients from a distance and has been shown to reduce heart failure admissions and death in patients with heart failure from any cause. Due to reduced access to primary and secondary care during COVID-19 the investigators instigated tele-monitoring of heart failure in ATTR amyloid patients. This appeared to be an effective intervention in the pilot study. The investigators propose to monitor the weight of patients with cardiac amyloidosis at home and intervene where a build up of fluid is observed by telephone discussion with a doctor. The investigators propose to evidence this in a prospective clinical trial. The investigators will evaluate the effect fairly by comparing tele-monitoring with usual care.

This is a joint project by Sahlgrenska University Hospital: Sahlgrenska, Östra and Mölndal. Our objective is to diagnose and map patients with well phenotyped cardiomyopathies (CMP) including in depth clinical and molecular phenotyping to enable earlier and specific treatment. The project will serve as: resource for diagnostic and therapeutic trials common biomaterial bank resource for detailed molecular analyses on patients' biomaterials and patient specific symptoms and examination results

The purpose of this research study is to assess safety and tolerability of a single intravenous (given through a vein) dose of the investigational retinal tracer AMDX-2011P in patients with cerebral amyloid angiopathy (CAA).

This study mainly evaluated the efficacy and safety of autologous stem cell transplantation for the treatment of AL amyloidosis, the role of induction and maintenance therapy in autologous stem cell transplantation, and the long-term efficacy and prognosis risk factors of autologous stem cell transplantation for the treatment of AL amyloidosis.

White matter hyperintensities (WMH) are one of the small vessel disease-related MRI characteristics of both cerebral amyloid angiopathy (CAA) and hypertensive arteriopathy (HA). WMH tend to show a peri-basal ganglia pattern in HA, whereas a multiple subcortical spots pattern can be observed in CAA. Periventricular WMH (PVWMH) have been reported to be posterior predominant using a semiautomated segmentation method and logarithmic transformation, not used in daily clinical practice. In these studies including CAA patients, patients initially presented with haemorrhage-related symptoms. In another study analysing PVWMH and cerebral amyloid evidence in patients with mild cognitive impairment, frontal PVWMH burden was associated with high uptake on florbetapir-PET whereas parietal and occipital PVWMH burden was associated with low CSF-amyloid-beta. The aim of this study is the descriptive comparative analysis of the distribution of PVWMH between CAA and HA patients with radiological tools available in daily practice.

The primary purpose of this protocol is to create a registry of older (≥50 years old) patients with Hematologic Malignancies. Our main objectives include: To understand the prevalence of frailty and geriatric impairments among patients aged ≥50y and above diagnosed with a hematologic malignancy at UAB and to gather information that would lend support for future research in this vulnerable population.

The primary objective of this study is to define the intracardiac flow imaging biomarkers in cardiac amyloidosis.

This is a mono-center observational ambispective study in which patients with cardiac amyloidosis evaluated at our institution will be enrolled. The primary aim is to investigate echocardiographic findings, particularly using advanced echocardiographic techniques, such as two- and three-dimensional speckle-tracking analysis, that may be helpful in the differential diagnosis between cardiac amyloidosis and other cardiomyopathies with hypertrophic phenotype. Secondary aims are: 1) to evaluate the reversibility of myocardial damage, assessed by echocardiography, in response to a newly available specific treatment for patients with transthyretin-related cardiac amyloidosis (tafamidis ) and its correlation with the clinical response 2) to investigate potential novel echocardiographic predictors of adverse cardiovascular outcomes.

This study will determine the prevalence of transthyretin amyloidosis in pathology of the transverse carpal ligament and cardiac involvement using natriuretic peptides, electrocardiography and echocardiography in patients referred for carpal tunnel release surgery of idiopathic carpal tunnel syndrome. This study will describe the relationship between amyloid deposition observed on the transverse carpal ligament and the presence of cardiac involvement.
