MS DMTs and the coronavirus
The National Multiple Sclerosis (MS) Society has provided guidance on the use of disease-modifying therapies (DMTs) during the COVID-19 pandemic. “There are numerous recommendations circulating that attempt to provide clarity and guidance, however, differences among the recommendations have created confusion,” the society says. “DMT decision making varies significantly from country to country, ranging from highly provider-directed to a collaborative decision-making model. ... DMT decisions should be individualized and made collaboratively between the person with MS and his/her healthcare provider.”
Patients with MS and their physicians should weigh risks and benefits before starting cell-depleting DMTs such as alemtuzumab, cladribine, ocrelizumab, or rituximab, according the National MS Society. They also should consider the risks and benefits of DMTs that carry warnings of a potentially severe increase in disability after stopping therapy, such as fingolimod and natalizumab. “We endorse the global advice provided by the MS International Federation (MSIF) – but emphasize that DMT decision making must be individualized and based upon multiple factors,” the National MS Society said.
Neurologists currently lack evidence about how COVID-19 affects patients with MS, according to the MSIF, which based its DMT guidance on advice from MS neurologists and research experts from member organizations. Many DMTs suppress or modify the immune system, and “some MS medications might increase the likelihood of developing complications from a COVID-19 infection but this risk needs to be balanced with the risks of stopping treatment,” according to the federation.
Patients currently taking DMTs should continue treatment, and those who develop symptoms of COVID-19 or test positive for the infection should discuss their DMT with a health care professional familiar with their care, the MSIF recommends. Decisions about starting a DMT should take into account a patient’s disease course, disease activity, and regional COVID-19 risks, according to the federation. For patients due to start DMT, treatments that do not reduce lymphocytes, such as interferons, glatiramer acetate, or natalizumab, should be considered.
Fingolimod, dimethyl fumarate, teriflunomide, and siponimod “may reduce the ability of the immune system to respond to an infection,” and “people should carefully consider the risks and benefits of initiating these treatments during the COVID-19 pandemic,” according to the federation. “People with MS who are currently taking alemtuzumab, cladribine, ocrelizumab, rituximab, fingolimod, dimethyl fumarate, teriflunomide or siponimod and are living in a community with a COVID-19 outbreak should isolate as much as possible to reduce their risk of infection.”
Extended isolation during the COVID-19 outbreak may be warranted for patients with MS who have recently undergone autologous hematopoietic stem cell treatment, which entails intensive chemotherapy, the guidance says. In addition, postponement of this procedure should be considered.
Child neurology, migraine, movement disorders, and stroke
The Child Neurology Foundation (CNF) and Child Neurology Society (CNS) published a joint statement about COVID-19. “Most children who contract COVID-19 appear to exhibit only mild symptoms,” said Scott Pomeroy, MD, president of CNF’s board of directors and chair of the department of neurology at Boston Children’s Hospital, in the statement. “However, if your child is taking a medication such as steroids that can lower their immune system response, there could be an increased risk for more significant symptoms. In addition, children with lung disease, such as asthma, may also be at higher risk. Therefore, it is important to practice preventative precautions. We hope that this information will help to reduce some of the fears that families in our community may be experiencing.”
The American Migraine Foundation shared COVID-19 considerations for patients with migraine from Mia Minen, MD, associate professor of neurology and population health at NYU Langone in New York. Patients with migraine who are otherwise in good health are not expected to be at increased risk of severe COVID-19, according to Dr. Minen. Best practices include having an adequate supply of medicine, considering alternatives to in-person doctor visits, and being “mindful of routine and diet to reduce migraine triggers,” the foundation suggests. In addition, patients should try to limit stress and seek out “alternative methods of social interaction.”
“The relationship between COVID-19 and Parkinson’s disease or other movement disorders remains unknown,” the International Parkinson and Movement Disorder Society said. “In general, we recommend that our movement disorder patients do not assume they are at extreme risks, which for the time being are uncertain. Nevertheless, we strongly recommend following the standard measures strictly to avoid exposures to the virus.”
The American Heart Association (AHA) cautions that older patients with coronary heart disease or hypertension “may be more likely than others to be infected by the coronavirus that causes COVID-19 and to develop more severe symptoms.” In addition, people with a history of stroke “may face a higher risk of complications,” according to the AHA. “As a result, people who have heart disease or another underlying condition should stay home to limit their risk of contracting the virus.”
Several groups emphasized the importance of telemedicine as an option for patients with neurologic conditions during the pandemic. The American Headache Society has hosted discussions on conducting neurologic exams via telemedicine. The American Academy of Neurology also conducted a webinar on telemedicine and COVID-19 and created a page with COVID-19 resources. The journal Neurology is publishing invited commentaries about neurologic aspects of the COVID-19 pandemic.
