Black Women With the TTR V122I Variant Have Increased Risks of CVD and Mortality

A new study has revealed that Black women who carry the transthyretin (TTR) V122I variant, a common variant in patients with hereditary transthyretin amyloidosis (hATTR), are at greater risk of cardiovascular disease (CVD) and all-cause mortality than noncarriers. The study, published in the Journal of the American College of Cardiology: Heart Failure, found the times…


Study Explores Phenotypes Associated With hATTR Variants

Neurologic and cardiac characteristics associated with hereditary transthyretin amyloidosis (hATTR) variants that are common in the US, including V122I, L58H, and late-onset V30M, have been explored in a study published in Neurology. The researchers conducted a retrospective case series of patients diagnosed with hATTR between January 2008 and January 2020. Of 56 patients with treatment-naive…

Link Found Between TTR Microenvironment and S100 Expression in hATTR

The presence of the TTR V30M variant affects the expression of members of the S100 family of calcium-binding proteins, thus likely contributing to the impaired immune response in patients with hereditary transthyretin amyloidosis (hATTR), according to a study published in Amyloid. The study was conducted by a research team from Portugal who found decreased levels…

New Clinical Trial to Evaluate 18F-Fluoride PET Imaging in Cardiac hATTR

A new prospective, case-control study will investigate the use of 18F-fluoride positron emission tomography (PET) for monitoring tafamidis treatment response in patients with cardiomyopathy associated with hereditary transthyretin amyloidosis (hATTR). The study is currently recruiting. The researchers plan to enroll 140 participants with cardiac hATTR, cardiac light chain amyloidosis, or hypertrophic cardiomyopathy. All patients must…

Inotersen Effective in Slowing Neuropathic Progression in hATTR

A new study has evaluated inotersen’s ability to slow neuropathic progression, as assessed by the Neuropathy Impairment Score (NIS), in patients with hereditary transthyretin amyloidosis (hATTR). The study, published in BMC Neurology, also estimated responder definition thresholds for the NIS and NIS lower limb subscale (NIS-LL) to reflect the clinically meaningful benefit of inotersen therapy…

Trial Will Evaluate Iodine-124 Evuzumitide in Patients With Systemic Amyloidosis

Recruiting is underway for a single-center prospective clinical trial evaluating iodine-124 evuzumitide (124I-evuzumitide) in patients with systemic amyloidosis, of which hereditary transthyretin amyloidosis (hATTR) is a form. The trial aims to “identify and characterize the distribution and uptake of 124I-evuzumitide in patients with transthyretin amyloid cardiomyopathy (ATTR-CM)” and correlate 124I-evuzumitide uptake with the structure and…

An Unusual Presentation of Periorbital Purpura in a Patient With hATTR

Periorbital purpura has been described as a presenting sign in a patient with hereditary transthyretin amyloidosis (hATTR). The case report is published in Annals of Internal Medicine: Clinical Cases. Amyloidosis is associated with deposits of misfolded precursor protein into extracellular tissues in the body, leading to organ dysfunction. Among more than 30 different amyloidogenic proteins,…
