Hereditary transthyretin amyloidosis - from symptomatic to curative treatment? : [Ärftlig transtyretinamyloidos – från lindring till potentiell bot]

Hereditary transthyretin (ATTRv) amyloidosis is a rare but life-threatening multi-systemic disease with clustering areas in, for example, northern Sweden. Until the 1990s, only symptomatic treatments were available but liver transplantation has, in selected patients, been a good therapeutic option since. The first disease-modifying drug for ATTRv amyloidosis was approved in 2011 and since then, the development of new therapeutic drugs has been rapid and successful. Two gene silencing therapies were approved for the disease in 2018, both showing a robust reduction in serum transthyretin levels and a satisfactory safety profile. Recently, CRISPR-Cas9 gene editing has also shown promising results in patients with ATTRv amyloidosis. The recent developments have had a paramount effect on the management of these patients, and will probably also have a significant positive effect on their life expectancy. However, treatment costs have skyrocketed, which implies future challenges.
