Induction therapy is recommended before autologous stem cell transplantation (ASCT) for AL amyloidosis patients with high disease burden [bone marrow plasma cells (BMPCs) > 10%], but the role of induction therapy before ASCT in patients with low disease burden (BMPCs ≤ 10%) is still unknown. ⋯ Our study demonstrated that low disease burden AL patients who are eligible for ASCT may benefit from bortezomib-based induction therapy.

Arterial thrombo-embolic events in cardiac amyloidosis: a look beyond atrial fibrillation.
Intracardiac thrombosis is reported to occur frequently in cardiac amyloidosis (CA). However, data regarding arterial thrombo-embolic events (AEs) in CA are limited. We aimed at assessing prevalence, clinical characteristics and predictors of AEs in a large multicentric CA cohort. ⋯ In our large, multicentric, real-world cohort, prevalence and incidence rate of AEs was high. A consistent proportion of events occurred despite anticoagulation therapy or in patients in sinus rhythm. A higher CHA2DS2-VASc score might identify patients at risk of AEs also among those in sinus rhythm.

Retinal angiopathy is a known ocular manifestation of hereditary transthyretin amyloidosis (ATTRv). Optical coherence tomography angiography (OCT-A) is a recent noninvasive imaging technique, used in other retinal vascular diseases. Our purpose was to analyse subclinical changes in retinal vessels, with OCT-A, in patients with ATTRv amyloidosis. ⋯ Scalloped iris in ATTRv eyes are associated with a more advanced subclinical retinal angiopathy, than eyes without scalloped iris. Our results identify for the first time and in vivo, early changes in retinal vessels in ATTRv amyloidosis. Henceforward, OCT-A may play a role in the evaluation of ATTRv patients oculopathy and the effectiveness of future eye targeting treatments.
