- ATTR amyloidosis during the COVID-19 pandemic: insights from a global medical roundtablePublication . Brannagan, Thomas H.; Auer-Grumbach, Michaela; Berk, John L.; Briani, Chiara; Bril, Vera; Coelho, Teresa; Damy, Thibaud; Dispenzieri, Angela; Drachman, Brian M.; Fine, Nowell; Gaggin, Hanna K.; Gertz, Morie; Gillmore, Julian D.; Gonzalez, Esther; Hanna, Mazen; Hurwitz, David R.; Khella, Sami L.; Maurer, Mathew S.; Nativi-Nicolau, Jose; Olugemo, Kemi; Quintana, Luis F.; Rosen, Andrew M.; Schmidt, Hartmut H.; Shehata, Jacqueline; Waddington-Cruz, Marcia; Whelan, Carol; Ruberg, Frederick L.Background: The global spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection causing the ongoing coronavirus disease 2019 (COVID-19) pandemic has raised serious concern for patients with chronic disease. A correlation has been identified between the severity of COVID-19 and a patient's preexisting comorbidities. Although COVID-19 primarily involves the respiratory system, dysfunction in multiple organ systems is common, particularly in the cardiovascular, gastrointestinal, immune, renal, and nervous systems. Patients with amyloid transthyretin (ATTR) amyloidosis represent a population particularly vulnerable to COVID-19 morbidity due to the multisystem nature of ATTR amyloidosis. Main body: ATTR amyloidosis is a clinically heterogeneous progressive disease, resulting from the accumulation of amyloid fibrils in various organs and tissues. Amyloid deposition causes multisystem clinical manifestations, including cardiomyopathy and polyneuropathy, along with gastrointestinal symptoms and renal dysfunction. Given the potential for exacerbation of organ dysfunction, physicians note possible unique challenges in the management of patients with ATTR amyloidosis who develop multiorgan complications from COVID-19. While the interplay between COVID-19 and ATTR amyloidosis is still being evaluated, physicians should consider that the heightened susceptibility of patients with ATTR amyloidosis to multiorgan complications might increase their risk for poor outcomes with COVID-19. Conclusion: Patients with ATTR amyloidosis are suspected to have a higher risk of morbidity and mortality due to age and underlying ATTR amyloidosis-related organ dysfunction. While further research is needed to characterize this risk and management implications, ATTR amyloidosis patients might require specialized management if they develop COVID-19. The risks of delaying diagnosis or interrupting treatment for patients with ATTR amyloidosis should be balanced with the risk of exposure in the health care setting. Both physicians and patients must adapt to a new construct for care during and possibly after the pandemic to ensure optimal health for patients with ATTR amyloidosis, minimizing treatment interruptions.
- Inotersen preserves or improves quality of life in hereditary transthyretin amyloidosisPublication . Coelho, Teresa; Yarlas, Aaron; Waddington-Cruz, Marcia; White, Michelle K.; Sikora Kessler, Asia; Lovley, Andrew; Pollock, Michael; Guthrie, Spencer; Ackermann, Elizabeth J.; Hughes, Steven G.; Karam, Chafic; Khella, Sami; Gertz, Morie; Merlini, Giampaolo; Obici, Laura; Schmidt, Hartmut H.; Polydefkis, Michael; Dyck, P. James B.; Brannagan III, Thomas H.; Conceição, Isabel; Benson, Merrill D.; Berk, John L.Objective: To examine the impact on quality of life (QOL) of patients with hATTR amyloidosis with polyneuropathy treated with inotersen (Tegsedi™) versus placebo. Methods: Data were from the NEURO-TTR trial (ClinicalTrials.gov Identifier: NCT01737398), a phase 3, multinational, randomized, double-blind, placebo-controlled study of inotersen in patients with hATTR amyloidosis with polyneuropathy. At baseline and week 66, QOL measures-the Norfolk-QOL-Diabetic Neuropathy (DN) questionnaire and SF-36v2® Health Survey (SF-36v2)-were assessed. Treatment differences in mean changes in QOL from baseline to week 66 were tested using mixed-effect models with repeated measures. Responder analyses compared the percentages of patients whose QOL meaningfully improved or worsened from baseline to week 66 in inotersen and placebo arms. Descriptive analysis of item responses examined treatment differences in specific activities and functions at week 66. Results: Statistically significant mean differences between treatment arms were observed for three of five Norfolk-QOL-DN domains and five of eight SF-36v2 domains, with better outcomes for inotersen than placebo in physical functioning, activities of daily living, neuropathic symptoms, pain, role limitations due to health problems, and social functioning. A larger percentage of patients in the inotersen arm than the placebo arm showed preservation or improvement in Norfolk-QOL-DN and SF-36v2 scores from baseline to week 66. Responses at week 66 showed more substantial problems with daily activities and functioning for patients in the placebo arm than in the inotersen arm. Conclusion: Patients with hATTR amyloidosis with polyneuropathy treated with inotersen showed preserved or improved QOL at 66 weeks compared to those who received placebo.
