Background: Hereditary transthyretin amyloidosis (ATTRv) is a treatable multisystem disorder with prevalent peripheral nervous system impairment. Besides neurophysiological measures, there are few markers to monitor disease progression. Neurofilament light chain (NfL) has recently been considered a sensitive biomarker for neuroaxonal damage in this setting. Objective: To evaluate NfL levels in a cohort of ATTRv patients and pre-symptomatic carriers and correlate the serum concentrations with other markers of disease severity. Methods: We analysed NfL serum from 17 ATTRv patients or carriers and 26 controls. An exhaustive clinical and instrumental evaluation was performed in all patients. Results: NfL levels were significantly higher in ATTRv cases when compared with controls. A significant correlation was found between NfL values and NIS scale, Sudoscan values from feet, interventricular septum thickness, and Quality of Life-Diabetic Neuropathy (Norfolk QoL-DN) questionnaire. Conclusion: We confirm that NfL is a reliable and promising biomarker to evaluate the ATTRv severity and monitor its progression.

Abstract

Background: Hereditary transthyretin amyloidosis (ATTRv) is a treatable multisystem disorder with prevalent peripheral nervous system impairment. Besides neurophysiological measures, there are few markers to monitor disease progression. Neurofilament light chain (NfL) has recently been considered a sensitive biomarker for neuroaxonal damage in this setting. Objective: To evaluate NfL levels in a cohort of ATTRv patients and pre-symptomatic carriers and correlate the serum concentrations with other markers of disease severity. Methods: We analysed NfL serum from 17 ATTRv patients or carriers and 26 controls. An exhaustive clinical and instrumental evaluation was performed in all patients. Results: NfL levels were significantly higher in ATTRv cases when compared with controls. A significant correlation was found between NfL values and NIS scale, Sudoscan values from feet, interventricular septum thickness, and Quality of Life-Diabetic Neuropathy (Norfolk QoL-DN) questionnaire. Conclusion: We confirm that NfL is a reliable and promising biomarker to evaluate the ATTRv severity and monitor its progression.
