Generative AI Impact on Rheumatoid Arthritis Complications Diagnosis

Generative AI (GenAI) based on large language models (LLMs) is expected to improve the diagnosis and treatment of autoimmune diseases. We are studying how GenAI may affect the diagnosis of various complications of rheumatoid arthritis (RA). In a retrospective study using RA patients' EHR records, we will quantify physician adoption of GenAI predictions for RA complications and co-existing diseases. In a prospective observational study, we will assess the feasibility of using GenAI predictions as additional clinical information to help physicians make more complete diagnoses of RA complications and co-existing diseases, including complex, uncommon, or rare conditions.

Study of Captisol Enabled Melphalan and Pharmacokinetics for Patients With Multiple Myeloma or Light Chain Amyloidosis That Are Receiving an Autologous Transplant.

Captisol Enabled Melphalan, is a new formulation of the standard of care melphalan chemotherapy that in packaged in an inactive substance that is believed to help the chemotherapy be more stable (meaning that it doesn't lose its effect or need to be administered quickly after being mixed). It may also have fewer side effects such as problems with important levels of body electrolytes such as potassium, phosphorous and magnesium; and cause less kidney and heart damage\] than standard formulation melphalan. The purpose of this study is to determine if the investigators can achieve a certain level of Captisol Enabled Melphalan that would be best to use in treating Multiple Myeloma and AL Amyloidosis.

Prevalence and Post-surgical Outcomes of CARdiac Wild-type TransthyrEtin amyloidoSIs in Elderly Patients With Aortic steNosis Referred for Valvular Replacement.

Background: The prevalence of both senile cardiac amyloidosis (CA) and aortic stenosis (AS) markedly increases with age. Aortic stenosis increases left ventricular pressure overload. Cardiac deposits have been observed in AS and the amount of these deposits has been correlated to post-surgical outcome. As they are strong echocardiographic and cardiac MRI imaging similarities between CA and AS, the investigators hypothesized that the deposit observed in AS is transthyretin amyloid deposit. The investigators objective is to demonstrate that amyloid deposit is associated with poor outcomes following aortic stenosis surgical valve replacement. Materiel and methods: 180 patients with indication for surgical aortic valve replacement will be recruited prospectively and consecutively in 5 French centers. A replicative study will be performed in one Austrian center. Echocardiography, cardiac MRI and bone scintigraphy will be performed prior to surgery. During surgery, a basal LV septum biopsy will be collected for determination and quantification of interstitial deposits using specific staining which will be performed in a blind fashion. Clinical outcomes will be recorded during the hospitalization period following the surgery and at 1 year. Alive and re-hospitalization status will be determined. Patients will be classified according to the presence or not of amyloid deposits. Expected results and impact: This study will emphasize how pressure overload stress accelerates and magnifies amyloid deposition usually known to be related to cardiac aging process. It will develop reliable imaging tools and markers to detect cardiac amyloid deposition. Correlation between anatomopathologic analyses and the three different imaging technics will identify accurate imaging markers of CA. A risk stratification model based on amyloid deposits level for the clinical management of these patients will be created combining imaging and biological markers.

Impact of a Cardiac Rehabilitation Program on Patients With Cardiac Amyloidosis

The goal of this clinical trial is to learn if a structured cardiac rehabilitation program can help people with cardiac amyloidosis improve their ability to exercise and their quality of life. The main questions it aims to answer are: Does cardiac rehabilitation raise peak oxygen uptake (VO₂ peak), which shows how well the heart and lungs work during exercise? Is cardiac rehabilitation safe and practical for people with cardiac amyloidosis? How does cardiac rehabilitation affect other exercise measures, heart function, symptoms linked to autonomic dysfunction, and quality of life? This study has no comparison group. Researchers will measure each participant's results before and after the rehabilitation program. Participants will: Complete a cardiac rehabilitation program for 5 weeks. Have tests before the program starts and again about 3 months later. These tests include: A cardiopulmonary exercise test A heart function test using electrical impedance A questionnaire about quality of life A blood sample A blood pressure test to check for orthostatic hypotension The study will include adults aged 18 or older with transthyretin cardiac amyloidosis who are able to perform an exercise test.

The Cancer Connected Access and Remote Expertise Beyond Walls Program to Provide In-Home Cancer Treatment and Improve Treatment Satisfaction in Cancer Patients Living in the Florida Panhandle and Surrounding Areas

This phase II trial studies whether providing cancer treatment in the home is preferred over the traditional clinic setting and if it improves treatment satisfaction in cancer patients living in the Florida Panhandle and surrounding areas. Typically, drug-related cancer care is provided at a medical center which causes patients to have to spend considerable time away from their family, friends, and familiar surroundings. This may add to the physical, emotional, social, and financial burden for patients and their families during this difficult time in their lives. The Cancer Connected Access and Remote Expertise (CARE) Beyond Walls (CCBW) program uses a specialized care team trained to provide cancer treatment in the patient's home setting. It is designed to support remote connection between the home health team and providers and Mayo clinic. This may be preferred over the traditional clinic setting which may improve treatment satisfaction in cancer patients living in the Florida Panhandle and surrounding areas.

[18F]FT8 PET Imaging in Immunoglobulin Light Chain Amyloidosis

\[18F\]FT8, a derivative of 1-(4-pyridyl)-4-piperazinyl arene (\[18F\]TPZA), exhibits high affinity for AL amyloid in myocardial tissue sections and shows no significant binding to transthyretin amyloid. By comparing its diagnostic performance against established clinical methods, including echocardiography, contrast-enhanced MRI, and relevant laboratory tests, this study aims to establish \[18F\]FT8 as the basis for a robust PET protocol for the direct visualization and differential diagnosis of AL amyloidosis . The study preimarily evaluates the safety and diagnostic efficacy of \[18F\]FT8 PET imaging in human subjects.

Prevalence and Prediction of ATTR in Ambulatory Patients With HFpEF

Recent studies have shown that transthyretin amyloidosis (ATTR) can sometimes cause a type of heart failure where the pumping function of the heart is normal, also known as Heart Failure with Preserved Ejection Fraction (HFpEF) or diastolic heart failure. In this single center diagnostic study, we will evaluate for ATTR in patients with HFpEF in order to to determine how frequently this occurs and how we can predict which heart failure patients may have TTR amyloidosis. Our goal is to identify amyloidosis in heart failure patients earlier so that they can start treatment.

The study will have 2 phases (parts). The first phase of the study will test different doses of Belantamab Mafodotin. The second phase will test Belantamab Mafodotin at the dose level found to be safe and effective in phase 1

Carpal Tunnel Release With Risk Factors for Amyloidosis

Bilateral carpal tunnel syndrome has been demonstrated in previous literature to be a warning sign for potential amyloidosis. One study has been performed in which patients with bilateral carpal tunnel syndrome underwent tissue biopsy (either tendon sheath or transverse carpal ligament) at the time of carpal tunnel release to determine the strength of association as well as most common subtypes. However, no study has been done demonstrating whether or not patients with amyloid-positive carpal tunnel biopsy would benefit from an early referral to cardiology for a work-up of potential cardiac amyloidosis. In our study, patients with bilateral carpal tunnel symptoms who are indicated for carpal tunnel release would be identified in clinic and undergo biopsy for congo red staining at the time of surgery. All patients with positive biopsy results would be referred to cardiology. Outcomes would include the rate of amyloid positivity, common subtypes, and echocardiographic findings after cardiac referral.

To Evaluate the Long-term Safety and Tolerability of Acoramidis in Participants With Newly Diagnosed ATTR-CM (ACT-EARLY OLE)

Acoramidis Transthyretin Amyloidosis Prevention Trial in the Young (ACT-EARLY) Study in Asymptomatic Carriers of a Pathogenic TTR Variant

Transthyretin amyloidosis (ATTR) is a disease where the normally occurring transthyretin (TTR) protein falls apart and forms amyloid, a sticky plaque-like substance that accumulates in different organs in the body and can cause damage to the organ. There are two ways that the TTR protein can fall apart. One way occurs as a person ages, where the normal TTR protein can fall apart and form amyloid that may no longer be sufficiently cleared by the body. This type of ATTR is known as wild-type ATTR (ATTRwt). The other way occurs when a person inherits a defective TTR gene that causes the TTR protein to spontaneously fall apart. This form of the disease is known as variant ATTR (ATTRv) and can be detected in adults by a genetic test of their TTR gene before they age. Amyloid build-up in the heart causes the heart wall to become thick and stiff and can result in heart failure and even death. Accumulation of TTR amyloid in the heart is known as transthyretin amyloid cardiomyopathy or ATTR-CM. Amyloid can also deposit in the nerve tissues leading to nerve problems. Accumulation of TTR in the nerves is known as transthyretin amyloid polyneuropathy or ATTR-PN. Acoramidis is an experimental drug designed to bind tightly to TTR in the blood and stabilize its structure, so it does not form the harmful amyloid plaques that can cause damage to organs. This study is intended to determine if treatment with acoramidis in participants with ATTRv who have not yet developed any symptoms of disease can prevent or delay the development of ATTR-CM or ATTR-PN disease. If adults with an inherited defective TTR gene are treated early before any of the symptoms of disease have developed, it may be possible to delay the onset or prevent the disease entirely.

Prevalence and Significance of ATTR Aortic Valve Amyloidosis in Degenerative Aortic Stenosis

Cardiac amyloidosis is a restrictive cardiomyopathy with a potentially severe prognosis that can be life-threatening. It is linked in the vast majority of cases to a light chain deposition of immunoglobulin or transthyretin. Although myocardial involvement is predominant, other locations are possible: the atrioventricular conduction system, coronary arteries and valve leaflets. In systematic histological analyzes, deposits of amyloidosis infiltrating the aortic valve have been reported with a frequency of up to 74% for degenerative RA. The nature of these deposits has never been established because the immunostaining carried out all remained negative, probably due to decalcification prior to cutting. Currently, these deposits are considered to be local degenerative phenomena without clinical repercussions. However, the use of bone scintigraphy has shown a high prevalence, between 14 and 16%, of ATTR cardiac amyloidosis in patients with severe RA. The diagnosis of ATTR amyloidosis has been proven histologically in a few patients. Sequencing of the TTR gene has shown that they are mainly wild forms. In fact, the prevalence of transthyretin mutations in our local cohort is 20%. The objective of this study is to determine by proteomic analysis based on mass spectrometry, the prevalence of ATTR aortic valve amyloidosis in patients undergoing surgical valve replacement for degenerative aortic stenosis.
