Neuromyelitis optica practice and prescribing changes in the setting of Covid19: A survey of neurologists.

PURPOSE: This study reports and analyzes the findings from the responses of 192 neurologists in the United States and Canada to a new survey instrument distributed in April 2020 to assess NMO practice and prescribing changes during the Covid19 pandemic. PRINCIPAL RESULTS: 92% of responding neurologists considered their NMO patients to be at an elevated risk of acquiring Covid19. They also indicated sharp declines in visits, delays in treatment and related services, and several unmet needs deterring treatment. MAJOR CONCLUSIONS: There is a need for evidence-based, comprehensive guidelines for treating NMO patients amid healthcare crises moving forward.

Impact of COVID-19 on U.S. and Canadian neurologists' therapeutic approach to multiple sclerosis: a survey of knowledge, attitudes, and practices.

OBJECTIVE: To report the understanding and decision-making of neuroimmunologists and their treatment of patients with multiple sclerosis (MS) during the early stages of the SARS-CoV-2 (COVID-19) outbreak. METHODS: A survey instrument was designed and distributed online to neurologists in April 2020. RESULTS: There were 250 respondents (response rate 21.8%). 243 saw > = 10 MS patients in the prior 6 months (average 197 patients) and were analyzed further (92% USA, 8% Canada; average practice duration 16 years; 5% rural, 17% small city, 38% large city, 40% highly urbanized). Patient volume dropped an average of 79% (53-11 per month). 23% were aware of patients self-discontinuing a DMT due to fear of COVID-19 with 43% estimated to be doing so against medical advice. 65% of respondents reported deferring > = 1 doses of a DMT (49%), changing the dosing interval (34%), changing to home infusions (20%), switching a DMT (9%), and discontinuing DMTs altogether (8%) as a result of COVID-19. Changes in DMTs were most common with the high-efficacy therapies alemtuzumab, cladribine, ocrelizumab, rituximab, and natalizumab. 35% made no changes to DMT prescribing. 98% expressed worry about their patients contracting COVID-19 and 78% expressed the same degree of worry about themselves. > 50% believed high-efficacy DMTs prolong viral shedding of SARS-CoV-2 and that B-cell therapies might prevent protective vaccine effects. Accelerated pace of telemedicine and practice model changes were identified as major shifts in practice. CONCLUSIONS: Reported prescribing changes and practice disruptions due to COVID-19 may be temporary but could have a lasting influence on MS care.

Neuromyelitis optica testing and treatment: Availability and affordability in 60 countries.

BACKGROUND: We characterize the variations in availability and affordability of NMO diagnostic testing and treatment by geographic region and country-level income group. METHODS: A structured survey was distributed in English, French, and Spanish in late 2018 to neurologists and other physicians who encounter NMO patients. RESULTS: Respondents (response rate 45%, 64/143 countries contacted) came from all WHO world regions and World Bank country income levels (49% university-based; 13 low-, 16 lower middle-, 16 upper-middle-, and 15 high-income countries). The average cost of an aquaporin-4 antibody (AQP4-Ab) test to a patient globally was 209 USD, and the average cost of NMO treatment per year was 3,819 USD. AQP4-Ab and myelin oligodendrocyte glycoprotein-antibody (MOG-Ab) testing were available in 68% and 38% of all countries. Low-income countries had poor availability of both AQP4-Ab (2/13 countries) and MOG-Ab (1/13) compared to high-income countries (15/15 AQP4-Ab, 13/15 MOG-Ab). Nearly half (48%, 13/27) of African and Eastern Mediterranean countries had access to neither test. GLOBAL TREATMENT AVAILABILITY AND USAGE: Azathioprine (88%), rituximab (50%), mycophenolate mofetil (57%), intravenous methylprednisolone (98%), oral prednisone (68%), plasma exchange (78%), intravenous immunoglobulin (72%). Whereas 70-100% of high-income countries' patients could afford treatment without incurring a catastrophic health expenditure, <10% of low-income country patients could. Most low-income countries (12/13) reported the patient pays for NMO care entirely without public assistance CONCLUSIONS: There is a gap in access to diagnostic testing for NMO in non-high-income countries, even in countries where acute and immunosuppressive treatment for NMO are available.
