Economic and healthcare resource utilization for hereditary transthyretin amyloidosis with polyneuropathy in Spain: real-world insights from early-stage patients and mutation carriers

OBJECTIVE: Variant transthyretin (ATTRv) amyloidosis is a rare genetic multisystem disease inducing progressive morbidity. Evidence about its economic burden is scarce. This study estimated annual use and costs of healthcare-resource-utilization (HRU) and indirect costs for ATTRv mutation carriers and patients with polyneuropathy from a societal perspective in Spain. METHODS: A cross-sectional, retrospective non-interventional multicenter study was conducted in 2018-2020 to characterize asymptomatic carriers of mutations in the TTR gen (AC) and Coutinho stage 1 transthyretin amyloidosis polyneuropathy patients (PA). HRU, associated costs, and indirect wages were assessed during 12 months prior to enrollment. CONCLUSIONS: Both AC and early-stage ATTRv-PN patients showed a meaningful economic burden to the National Health System and society. We observed an annual incremental economic burden of €1,771.5 in PA versus AC.
