Database will collect data on COVID-19 in patients with MS
The COViMS (COVID-19 Infections in Multiple Sclerosis and Related Diseases) database is gathering information from patients throughout the United States and will soon gain access to Canadian data. Data from patients with CNS demyelinating diseases such as neuromyelitis optica and myelin oligodendrocyte glycoprotein antibody diseases also will be included in COViMS. Amber Salter, PhD, MPH, the director of the North American Research Committee on MS (NARCOMS) is supervising the data collection and analyses.
“COViMS will provide valuable insight on how COVID-19 affects people with MS, including if certain disease-modifying treatments incur special risks,” said June Halper, CEO of CMSC, in a press release.
The project began when CMSC and NMSS established independent registries of epidemiologic data related to MS and COVID-19. The two groups soon began communicating and included other researchers, who also were considering establishing registries, in their discussions. In addition, representatives of the Cleveland Clinic verbally agreed to share data that they have been collecting with the COViMS registry. “The fast-moving, almost parallel, efforts led to this collaboration,” said Gary Cutter, PhD, professor of biostatistics at the University of Alabama at Birmingham. “This in itself is noteworthy because all of this took place within an incredibly short time from inception to the initiation of data collection.”
The effects of SARS-CoV-2 infection on the health of patients with MS is little understood. In North America, no reporting system had been organized to gather information on these patients and track outcomes. Such a system could influence the treatment of people with MS who become infected with the novel coronavirus or other similar future viruses. The COViMS registry is intended to define the impact of COVID-19 on patients with MS and ascertain how factors such as age, comorbidities, and MS treatments affect outcomes of COVID-19. “The estimated median age of MS patients in the U.S. is about 52 years, thus putting many at increased risk just due to age,” said Dr. Cutter.
“People with MS and their health care providers need evidence-based guidance to provide optimal MS care during the COVID-19 pandemic, and the COViMS database will help answer the many pressing questions,” said Bruce Bebo, executive vice president of research for the NMSS, in a press release.
The two organizations encourage neurologists and other health care providers who treat patients with MS and documented COVID-19 infection to complete a Case Report Form on the COViMS website, which includes answers to frequently asked questions, a sample CRF, and other resources. The website will provide real-time data once registry participation is underway.

FDA removes pregnancy category C warning from certain MS medications
The FDA based the decision on data from more than 1,000 real-world pregnancies, including pregnancies from a large epidemiologic study and published studies over several decades, which found no connection between use of interferon-beta products during early pregnancy and an increased risk of major birth defects, according to the FDA.
As a result, the labels for both medications will no longer have the pregnancy category C designation; however, patients should continue to notify their health care provider if they are pregnant or plan to become pregnant.
The FDA decision to remove the warning follows a similar decision by the European Medicines Agency last year.
“Many women with MS are diagnosed during their childbearing years. With this important update for Plegridy and Avonex, healthcare providers have more data to inform appropriate treatment paths for patients who may be pregnant or planning for pregnancy,” said Bernd Kieseier, MD, MHBA, executive director and head of global MS at Worldwide Medical, Biogen, in a press release.

Cognitive reserve may play protective role in MS-related cognitive dysfunction
Key clinical point: Cognitive reserve (CR) is strongly associated with cognitive function in patients with multiple sclerosis (MS); CR along with disability and depressive symptoms explained up to roughly 23.7% of the cognitive performance.
Major finding: Cognitive impairment (CI) was detected in 202 (38.4%) patients. The CR Index questionnaire (CRIq) score was lower in patients with CI vs. those without (94.8±11.6 vs. 102.2±14.1; P less than .001). CRIq score significantly correlated with information-processing speed, verbal memory, and visuospatial memory (P less than .001 for all). Higher CRIq was associated with lower disability and depressive symptoms (P less than .001 for both).
Study details: Cross-sectional study of 526 MS outpatients (70.9% female patients; mean age, 41.7±11.1 years); CR was assessed by the CRIq.
Disclosures: No study sponsor was identified. Dr. Bakirtzis and Prof. Grigoriadis reported receiving research funding and/or honoraria from multiple pharmaceutical companies. The remaining authors reported no conflict of interest.

Higher incidence of trigeminal neuralgia in patients with MS
Key clinical point: The incidence of trigeminal neuralgia (TN) is 15-fold higher in patients with multiple sclerosis (MS) compared with the general neurological outpatient population.
Major finding: Concomitant diagnoses of MS and TN were verified in 55 patients, giving a prevalence of 2.1% for TN in patients with MS. Patients with MS had a significantly higher incidence of TN vs. general neurological outpatient population (149 vs. 9.9 per 100,000 person-years). A demyelinating lesion in the proximity of the trigeminal ganglia was observed in 26 (63%) of the 41 patients with a concomitant MS diagnosis and with magnetic resonance imaging scans available.
Study details: Single-center retrospective study included 2,575 patients with MS and 2,008 patients with a diagnosis of TN using data from the Finnish MS register.
Disclosures: The presenting author received fee for lecture from Merck; congress expenses from Roche, Merck. Funding for building the Finnish MS registry was received from Biogen Idec, Merck, Novartis, Sanofi-Genzyme, Roche, Teva, and Business Finland.

Exposure to passive smoking during adolescence tied to MS risk
Key clinical point: Exposure to passive smoking during adolescence is a strong risk factor for developing multiple sclerosis (MS) in later life.
Major finding: Among never smokers, female patients with MS more often than healthy control participants reported exposure to passive smoking between the age of 10 and 19 years (women: odds ratio [OR], 1.432; P = .037 and men: OR, 1.232; P = .390). Among active smokers aged 19 years or older, male MS patients more often than male control participants reported with passive smoking (men: OR, 1.593; P = .022 and women: OR, 1.102; P = .440).
Study details: The data come from a case-control study of 919 MS cases and 3,419 controls (never active smokers: 342/822 cases/controls; active smokers aged 19 years or older: 577/2,597 cases/controls).
Disclosures: This study was supported by grants from the Danish Multiple Sclerosis Society, the Danish Council for Strategic Research, Novartis, Biogen (Denmark), the Sofus Carl Emil Friis og Hustru Olga Doris Friis foundation, the Foundation for Research in Neurology, and the Director Einar Jonasson (Johnsen) and Wife foundation.

Fingolimod vs. natalizumab as second-line therapy for RRMS
Key clinical point: In patients with relapsing-remitting multiple sclerosis (RRMS), both fingolimod (FIN) and natalizumab (NTZ) reduce the annualized relapse rate (ARR), but ARR percent reduction is significantly higher with NTZ after 12 months of treatment.
Major finding: ARR reduction during the first year of treatment was statistically significant in both the groups, from 1.67±0.98 to 0.28±0.62 in the FIN group and from 1.71±1.37 to 0.12±0.33 in the NTZ group (P less than .0001 for both). Nevertheless, the ARR percent reduction was significantly higher in the NTZ group vs. FIN group during the first year of treatment (92.3% vs. 81.8%; P = .0064).
Study details: Retrospective, observational study compared the ARR over the first year in 314 patients with RRMS after the treatment with FIN (n = 184) or NTZ (n = 130) as a second-line therapy in routine clinical practice in Spain.
Disclosures: This study was funding by Novartis Farmaceutica, S.A. The authors declared no conflicts of interest.

Serum vitamin D inversely associated with clinical and disease activity in MS
Key clinical point: Low serum levels of vitamin D are inversely associated with clinical and disease activity in patients with multiple sclerosis (MS).
Major finding: Patients with serum 25(OH)D levels ≥30 ng/mL group had lower median T2-weighted lesion counts than those with <30 ng/mL (P = .03; adjusted for age, sex, 25(OH)D levels, and disease duration, P less than .001). Expanded disability status scale (EDSS) score had an inverse association with serum 25(OH)D levels after adjusting for age, sex, and disease duration (adjusted P less than .001).
Study details: The study analyzed baseline serum vitamin D levels of patients recruited in the randomized Efficacy of Vitamin D Supplementation in Multiple Sclerosis (EVIDIMS) study.
Disclosures: The study was funded by the German Research Organization grants awarded to FP and JD, the Einstein Foundation Berlin, and a limited research grant from Bayer Leverkusen, Germany.

MS in pregnancy: Maintenance of natalizumab during the first trimester is beneficial
Key clinical point: Continuation of natalizumab during the first trimester may lower the risk for disease reactivation during pregnancy in patients with active multiple sclerosis (MS).
Major finding: The secured first trimester (SFT) group vs secured conception (SC) group was associated with lower rates of relapse (3.6% vs 38.5%; P = .008) and disability progression (3.6% vs 30.8%; P = .03) during pregnancy.
Study details: Two strategies were compared for women with active MS planning to conceive: stopping natalizumab at the end of the first trimester (SFT, n = 29) and stopping at conception (SC, n = 14).
Disclosures: The study did not receive any funding. Audrey Rico, Adil Maarouf, Clémence Boutiere, Jean Pelletier and Bertrand Audoin reported ties with one or more pharmaceutical companies. Sarah Demortiere reported no disclosures.

High serum homocysteine levels in patients with MS
Key clinical point: Patients with multiple sclerosis (MS), particularly those with relapsing-remitting MS (RRMS) have higher serum levels of homocysteine (Hcy).
Major finding: The MS group had higher serum levels of Hcy (standardized mean difference [SMD], 0.64; P less than .0001) compared with the control group. There were no significant differences in levels of vitamin B12 (SMD, –0.08; P = .58) or folate (SMD, 0.07; P = .52) between the MS and control groups. There was a statistically significant difference for Hcy between patients with RRMS and control individuals (SMD, 0.67; P = .004) but not between patients with primary or secondary progressive MS and control individuals.
Study details: A meta-analysis of 21 studies, including 1,738 patients with MS and 1,424 control individuals.
Disclosures: The study was supported by the National Natural Science Foundation of China and the Beijing Municipal Administration of Hospitals Incubating Program. The authors declared no conflicts of interest.
